The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

Please refer to Figures 1 and 2. The present invention provides an adjustable mechanism of a frame, including: a movable plate 3 movably arranged at one end of a frame body 1, and an adjusting support mechanism 5 and an adjusting mechanism 7 arranged beside the movable plate 3. The adjusting support mechanism 5 and the adjusting mechanism 7 are respectively arranged on both sides of the movable plate 3. The adjusting support mechanism 5 clamps one side of the movable plate 3 and drives the movable plate 3 to move along the frame body 1. The adjusting mechanism 7 approaches the movable plate 3 from the other side of the movable plate 3 and cooperates with the adjusting support mechanism 5 to adjust the movable plate 3 longitudinally.

The adjustable support mechanism 5 includes: a first motor 51 disposed beside the frame body 1, a first transmission mechanism 52 connected to the output end of the first motor 51, a first slide 53 connected to the output end of the first transmission mechanism 52, a plurality of first cylinders 54 disposed on the first slide 53, and a first clamping plate mechanism 55 disposed on the output end of the first cylinder 54. The adjustable support mechanism 5 can not only adjust the longitudinal position of the movable plate 3, but also take into account the force applied by the clamping mechanism to the lower frame clamp. The opening width of the first clamping plate mechanism 55 corresponds to the width of the movable plate 3, and the movable plate 3 can be clamped and limited through the opening of the first clamping plate mechanism 55. The first motor 51 drives the first slide 53 to move up and down through the first transmission mechanism 52. The first cylinder 54 drives the first clamping plate mechanism 55 to move forward and embed the movable plate 3 in the opening of the first clamping plate mechanism 55. When the clamping position of the frame body 1 needs to be adjusted according to the size of the product, the first cylinder 54 is started and clamped and connected with the movable plate 3 through the first clamping plate mechanism 55. The first motor 51 is started again, and the first slide 53 is driven to move through the first transmission mechanism 52, thereby driving the movable plate 3, so that the movable plate 3 moves up and down along the frame body 1, so as to adjust the size of the clamping position and meet the clamping requirements of fixed plates of different specifications.

The two ends of the movable plate 3 are respectively connected with sliding blocks 31, and the sliding blocks 31 are sleeved on the frame body 1, so that the movable plate 3 can slide and adjust along the frame body 1 under the drive of the adjustment support mechanism 5.

The first motor 51 adopts a servo motor. The servo motor has high control accuracy, good low-speed operation stability, and good torque-frequency characteristics. It can meet the driving requirements of the movable plate 3 and improve the accuracy of the movable plate 3 in adjusting the distance.

The first transmission mechanism 52 includes: a first screw 521 connected to the output end of the first motor 51, and a first screw slider 522 sleeved on the first screw 521. The first screw slider 522 is connected to the first slide platform 53. The screw transmission structure is simple, the installation and maintenance cost is low, the transmission axial force is large, it can be self-locking, and the positioning accuracy is high. It meets the requirements for the position adjustment of the movable plate 3 and improves the position adjustment accuracy and stability. Guide rails are arranged on both sides of the first slide platform 53. Through the cooperation between the guide rails and the slider, it is beneficial to the stability of the first slide platform 53 during the lifting process.

A fixed plate 2 is arranged at the other end of the frame body 1 relative to the movable plate, and a fixed support mechanism 4 is arranged beside the fixed plate 2. A plurality of frame clips 21 are arranged at equal distances on the fixed plate 2 and the movable plate 3. The fixed support mechanism 4 includes: a second cylinder 41 arranged beside the frame body 1, and a second top plate mechanism 42 arranged on the output end of the second cylinder 41. The second cylinder 41 drives the second top plate mechanism 42 to move forward and lean against the frame body 1. When the second cylinder 41 is started, the second top plate mechanism 42 provides support and positioning for the upper part of the frame body 1, thereby preventing the frame body 1 from tilting and being unable to be stably opened when the frame clips 21 are opened. When the frame clamp 21 on the upper part of the frame body 1 is opened and closed, the second cylinder 41 is started to push out the second top plate mechanism 42, thereby holding the frame body 1 to limit and fix its upper part. The first clamping plate mechanism 55 and the second top plate mechanism 42 are fixed on the frame, and the corresponding mechanisms are only set at the loading and unloading stations, thereby meeting the needs of fixing the fixed plate 2 and lifting and moving the movable plate 3.

Please refer to Figures 1 and 3. A clamping mechanism 6 is provided on the sides of the fixed plate 2 and the movable plate 3. The clamping mechanism 6 includes: a plurality of clamping cylinders 62, a clamping seat 63 connected to the output end of the clamping cylinder 62, and a plurality of clamping blocks 64 provided on the clamping seat 63. The clamping cylinder 62 of the clamping mechanism 6 above the movable plate 3 is provided on a cylinder mounting plate 61, and the cylinder mounting plate 61 is suspended above the movable plate 3. The clamping cylinder 62 of the clamping mechanism 6 above the fixed plate 2 is provided on the machine platform of the equipment. The setting position of the clamping block 64 corresponds to the frame clamp 21. The clamping cylinder 62 drives the clamping seat 63 to move toward the frame clamp 21, so that the clamping block 64 presses on the frame clamp 21 to open the frame clamp 21. Start the clamping cylinder 62, and the clamping block 64 presses on the frame clamp 21, so that the frame clamp 21 is forced to open, so as to clamp the upper end of the plate to be fixed.

The clamping mechanism 6 corresponding to the movable plate 3 is connected to the adjusting mechanism 7, and the adjusting mechanism 7 includes: a second motor 71, a second transmission mechanism 72 connected to the output end of the second motor 71, and a second slide table 73 connected to the output end of the second transmission mechanism 72, and the cylinder mounting plate 61 is arranged on the second slide table 73. After the clamping mechanism 6 corresponding to the fixed plate 2 is started and one end of the plate to be fixed is clamped, the clamping mechanism 6 above the movable plate 3 is driven to move by the adjusting mechanism 7, so as to ensure that the position of the clamping mechanism 6 after movement corresponds to the frame clamp 21 of the movable plate 3, so that the frame clamp 21 is opened normally by the clamping mechanism 6 to clamp and fix the plate material. The clamping mechanism 6 arranged beside the movable plate 3 is divided into multiple parts arranged at intervals, thereby making way for the lifting and lowering of the second transmission mechanism 72.

The clamping mechanism 6 on one side of the fixed plate 2 is started, so that the frame clamp 21 on the fixed plate 2 clamps the plate material on one side. The adjusting support mechanism 5 is started, the first cylinder 54 drives the first clamping mechanism 55 to move forward and the movable plate 3 is embedded in the opening of the first clamping mechanism 55, and then the first motor 51 is started, and the first slide 53 is driven to move through the first transmission mechanism 52, thereby driving the movable plate 3 to move up and down along the frame body 1. After the position adjustment of the movable plate 3 is completed, or during the process of adjusting the position of the movable plate 3, the clamping mechanism 6 on the side of the movable plate 3 is moved by the adjusting mechanism 7 to a position adapted to the movable plate 3, so as to meet the clamping work requirements of the frame clip 21 on the movable plate 3. When the clamping mechanism 6 clamps the frame clip 21 on the movable plate 3, the other side of the movable plate 3 is supported by the first clamping mechanism 55, and the first cylinder 54 is in an extended state, thereby providing a supporting force for the clamping work of the clamping cylinder 62, and ensuring the stability of the clamping effect of the clamping cylinder 62 on the frame clip 21 on the movable plate 3. As for the disengagement mechanism 6 above the fixed plate 2, since the setting position of the fixed plate 2 is fixed, the corresponding disengagement mechanism 6 is fixedly set on the machine platform of the equipment, which can effectively ensure the disengagement effect while reducing the parts set on the equipment.

The second transmission mechanism 72 includes: a belt pulley transmission mechanism 721 connected to the output end of the second motor 71, a second screw rod 722 connected to the output end of the belt pulley transmission mechanism 721, and a second screw rod slider 723 sleeved on the second screw rod 722. The second screw rod slider 723 is connected to the second slide table 73. By adopting the belt pulley transmission mechanism 721, the second motor 71 and the second screw rod 722 are not on the same straight line, avoiding the problem of the overall mechanism being too long and resulting in limited installation space. The second slide platform 73 is provided with a guide rail. Through the cooperation between the guide rail and the slider, the stability during the lifting process is guaranteed, and the sliding mechanism 6 can be connected to realize synchronous lifting.

Please refer to Figure 4. The clamping part of the frame clamp 21 is wavy, tooth-shaped or groove-shaped, which can effectively ensure the clamping effect of the plate by increasing the friction between it and the plate.

A plurality of anti-collision blocks are arranged on both sides of the frame body 1, thereby providing protection for the sides of the frame body 1 to avoid damage caused by collision or adverse effects on the clamping effect.

In summary, the present invention drives the first clamping plate mechanism to clamp and connect with the movable plate through the first cylinder, and then starts the first motor to drive the first slide table to move through the first transmission mechanism, thereby driving the movable plate to move up and down along the frame body, so as to adjust the clamping position size, cooperate with the frame clamp, fixed setting and lifting and lowering opening and closing elements and other mechanisms to meet the clamping requirements of fixed plates of different specifications.

The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
