Description

A Cam Manipulator with Adjustable Vertical Stroke

technical field

The utility model relates to the field of manipulators in industrial automation equipment, in particular to a cam manipulator with adjustable vertical stroke.

Background technique

Manipulator is an important part of industrial automation, and has a wide range of use values in automobile manufacturing and packaging industries. Compared with other complex manipulators, cam manipulators have been widely used in the non-standard automation industry due to their remarkable advantages such as precise action, long practical life, and stable action. However, in the actual application process of the cam manipulator, there is a disadvantage that the stroke is fixed and cannot be adjusted according to the actual working conditions. I have realized the adjustable horizontal stroke function of the cam manipulator in the patent of a cam manipulator with adjustable stroke (patent number: ZL201320250463).

In view of the above, it is necessary to provide a cam manipulator with strong versatility and whose vertical stroke can also be adjusted according to actual working conditions.

Utility model content

The technical problem to be solved by the utility model is to provide a cam manipulator with adjustable vertical stroke, which can realize the vertical stroke of the cam manipulator by adjusting the position of the vertical stroke adjustment device on the frame. function to make adjustments. The vertical stroke adjustable cam manipulator makes the cam manipulator more flexible and versatile while retaining many advantages of the existing manipulator's working performance and application.

In order to achieve the above-mentioned technical features, the technical features adopted by the utility model are: a cam manipulator with adjustable vertical stroke, which includes a frame, the bevel gear shaft is installed on the frame, and the bevel gear shaft is equipped with double cylinders Cam, the double cylinder cam drives the horizontal stroke adjustment device and the vertical stroke adjustment device to move at the same time. Movement in the vertical direction, the working device is installed on the mechanical arm.

The vertical stroke adjustment device includes a bracket, the bracket is fixed on the frame by screws, the lever is connected with the bracket through a slide groove, a roller is installed at one end of the lever, a pin is installed at one end, and the other end of the roller is located in the cam chute. The pin shaft is connected with the connecting seat, the connecting seat is fixed on the vertical rod, and the vertical rod is connected with the manipulator arm.

The supports are arranged symmetrically.

The vertical bars are symmetrically arranged.

The utility model has the following beneficial effects:

When it is necessary to adjust the vertical stroke of the manipulator, adjust the bracket. When the bracket moves to the right, the contact point between the bracket and the lever in the chute will move to the right, and the distance from the roller to the contact point is less than that from the pin shaft to the contact point. Since the pin shaft moves up and down around the contact point between the lever and the chute, the above adjustment increases the distance between the pin shaft and the contact point, that is, the length of one end of the lever increases, so its up and down stroke will also increase. Increase, and the up and down movement of the pin shaft will drive the up and down movement of the manipulator arm, and the vertical stroke of the manipulator will also increase at this time.

When the bracket moves to the left, the contact point between the bracket and the lever in the chute will move to the left, and the distance from the roller to the contact point is greater than the distance from the pin shaft to the contact point, because the pin shaft is around the contact between the lever and the chute If the point moves up and down, the distance between the pin shaft and the contact point is reduced through the above adjustment, that is, the length of one end of the lever is reduced, so its up and down stroke will also be reduced, and the up and down motion of the pin shaft will drive the movement of the manipulator arm. Moving up and down, the vertical stroke of the manipulator will be shortened at this time.

Loosen the screws of the fixing bracket. If you want to increase the vertical stroke of the manipulator, then move the bracket to the right to an appropriate position and fix the bracket on the frame with screws; otherwise, move the bracket to the left.

The above-mentioned brackets are symmetrically arranged, and the symmetrical structural arrangement enables the sliding and fastening of the brackets on the frame, ensuring the stability of the connection.

The above-mentioned vertical rods are arranged symmetrically, thereby ensuring that the manipulator moves more smoothly and stably along the vertical rods.

Referring to Fig. 3, preferably, the vertical rods 7-8 are arranged symmetrically.

Referring to Fig. 4, preferably, the brackets 7-2 are arranged symmetrically.

The embodiments of the utility model are described in detail in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Those skilled in the art can modify the above embodiments within the protection scope of the claims without violating the innovation points and operation steps of the present invention. The protection scope of the utility model should be covered by the claims of the utility model.

The concrete working principle of the device of the present utility model is:

1. Increase the vertical stroke: adjust the bracket 7-2, when the bracket 7-2 moves to the right, the contact point between the bracket 7-2 and the lever 7-3 in the chute 7-5 will move to the right, and the roller The distance from 7-6 to the contact point is less than the distance from the pin shaft 7-4 to the contact point. Since the pin shaft 7-4 moves up and down around the contact point of the lever 7-3 and the chute 7-5, through the above adjustment Increased the distance between pin shaft 7-4 and the contact point, that is, the length of one end of the lever increases, so its up and down travel will also increase, and the up and down motion of pin shaft 7-4 will drive the up and down motion of manipulator arm 2, thus At this time, the vertical travel of the manipulator will also increase.

2. Reduce the vertical stroke: adjust the bracket 7-2. When the bracket 7-2 moves to the left, the contact point between the bracket 7-2 and the lever 7-3 in the chute 7-5 will move to the left, and the roller will move to the left. The distance from 7-6 to the contact point is greater than the distance from the pin shaft 7-4 to the contact point. Since the pin shaft 7-4 moves up and down around the contact point of the lever 7-3 and the chute 7-5, through the above adjustment The distance between the pin shaft 7-4 and the contact point is reduced, that is, the length of one end of the lever is reduced, so its up and down stroke will also be reduced, and the up and down motion of the pin shaft 7-4 will drive the up and down motion of the manipulator arm 2 , at this time the vertical stroke of the manipulator will be shortened.

To sum up, loosen the screw 7-1 of the fixing bracket 7-2, if you want to increase the vertical stroke of the manipulator, move the bracket 7-2 to the right to a proper position and fix the bracket 7-2 with the screw 7-1 On the frame 6, otherwise, move the support 7-2 to the left.
