Through the through hole on the middle plate 2, the elastic guide post 15 on the longitudinal extrusion device can be inserted into the through hole on the transverse extrusion device, thereby driving the transverse extrusion device to move up and down.

A socket (not shown) for inserting the inclined slide block 12 is provided in the slide block 21 of the lateral pressing device. The bottom of the inclined slider 12 is formed with an inclined surface. When the longitudinal pressing device moves downwards, the inclined slide block 12 on the longitudinal pressing device presses the slide block 21 on the transverse pressing device to move towards the center of the middle plate 2, so that the rubber body is clamped.

In addition, the transverse extrusion device further comprises a fixed block 22 fixedly arranged on two sides of the sliding block 21 respectively, the fixed block 22 is fixed with the middle plate 2 through a screw 26, and then a bolt 24 penetrates through the fixed block 22 and is movably connected with the sliding block 21.

In order to restore the lateral compression device to its original uncompressed state, a second compression spring 23 is also provided between the bolt 24 attached to the slider 21 and the fixed block 22.

The base comprises a positioning block 31 mounted on the lower plate 3 for positioning a housing (not shown) to be fitted into the rubber body. When the longitudinal pressing device is rapidly displaced downwards, the pressing block 31 on the longitudinal pressing device presses the rubber body compressed by the sliding block 21 into the shell.

Preferably, in order to make the utility model discloses a colloid anchor clamps are more accurate reliable when assembling, at upper plate 1 and 2 relevant positions of hypoplastron, still are equipped with two sets of upper guide pillars 11 respectively and two sets of and upper guide pillars 11 lower spacing block 32 with the axle center, all put a second bush 33 in the spacing block 32 under two.

Preferably, in order to ensure the extrusion concentricity when the rubber body is extruded into the metal shell, the two lower limiting blocks 32 and the two upper guide pillars 11, the pressing block 14 and the positioning block 31 are respectively fixed coaxially. The two sliding blocks 21 are symmetrically and movably arranged on the middle plate 2 by taking the centers of the pressing block 14 and the positioning block 31 as axes.

Preferably, the sliding block 21, the inclined sliding block 12, the first bushing 25 and the second bushing 33 are all made of special wear-resistant materials.

Preferably, the upper plate 1 is vertically displaceable by inserting the elastic guide post 15 fixed to the upper plate 1 into the first bush 25 fixed to the through hole of the middle plate 2.

Preferably, the upper plate 1, the middle plate 2 and the lower plate 3 are square plates with various required threaded holes or slots.

When the longitudinal extrusion device is assembled, two identical upper guide posts 11 are fixed at the through holes at the opposite corners of the upper plate 1 by using set screws 18, the ejector pin 13 is embedded into the central through hole of the upper plate 1, the ejector pin 13 is pressed into the pressing block 14, the pressing block 14 is fixed on the upper plate 1 by using screws, and finally, the ends, which are not provided with oblique openings, of the two oblique slide blocks 12 are respectively fixed in the square holes in the upper plate 1.

When the transverse extrusion device is assembled, firstly, the two sliding blocks 21 are respectively arranged in the middle plate 2 along the grooves on the middle plate 2, secondly, the two fixing blocks 22 are respectively fixed in the grooves of the middle plate 2, and finally, two sets of bolts 24 with second compression springs 23 penetrate through the fixing blocks 22 and then are fixed with the sliding blocks 21. The elastic guide post 15 sleeved with the fixed seat 16 and the spring 19 penetrates into a through hole of the transverse extrusion device, and then the fixed seat 16 and the elastic guide post 15 are fixed on the upper plate 1 by using the socket head cap screw 17 and the set screw.

Similarly, a positioning block 31 and two lower limiting blocks 32 with second bushings 33 are fixed to the lower plate 3.

Preferably, the longitudinal pressing device can be fixed on a machine (not shown) capable of driving the longitudinal pressing device to move up and down in a linkage manner, and the lower plate 3 is fixed on a stationary table (not shown) of the machine.

The following rubber body and metal casing assembly is taken as an example to illustrate the working process of the rubber sleeve clamp of the utility model as follows:

the assembled upper plate 1 is fixed on a machine capable of linking up and down, the lower plate 3 is fixed on a static workbench of the machine, and the two lower limiting blocks 32 are coaxially opposite to the two upper guide pillars 11, the pressing block 14 and the positioning block 31 respectively.

A rubber body (not shown) is placed between the two sliders 21, and a metal shell (not shown) is placed at the center of the positioning block 31. The machine drives the longitudinal extrusion device to rapidly move downwards. Because the transverse extrusion device is not limited by the limit boss on the elastic guide post 15 when the longitudinal extrusion device moves downwards, and also moves downwards under the action of gravity and the elastic force of the spring 19 on the elastic guide post, when the longitudinal extrusion device cooperates with the inclined slide block 12 to move downwards to contact with the slide block 21 on the middle plate 2, the bottom inclined plane of the inclined slide block 12 is inserted into the socket on the slide block 21 to push the slide block to move towards the center, at the moment, the pushing force moving towards the center of the slide block is far greater than the elastic force of the spring 23 on the bolt connected on the slide block 21, so that the two slide blocks 21 rapidly move towards the center of the middle plate along the groove on the middle plate to clamp the rubber body, thereby reducing the diameter of the rubber body, namely forming the rubber body after diameter reduction.

When the lateral pressing means comes into contact with the metal shell placed on the positioning block 31, it is no longer moved downward. And the ejector pin 13 and the pressing block 14 on the longitudinal extrusion device continue to move until the rubber body which is reduced in diameter by extrusion is pressed into the metal shell. Meanwhile, each stepped surface on the upper guide post 11 is gradually contacted with the upper surface of the lower stopper 32, which is coaxial with the center of the shaft, so that the whole longitudinal pressing device is stopped without moving downward.

After the whole press-fitting process is completed, the machine drives the longitudinal extrusion device to move upwards, and the inclined slide block 12 is driven by the cooperation of the upper plate 1 to move upwards and is gradually separated from the slide block 21 on the middle plate 2. Meanwhile, the two sliding blocks 21 are respectively pulled to two sides by the bolt 24 under the action of the elastic force of the second compression spring 23, and the transverse extrusion device is gradually driven to move upwards after the limiting blocks of the elastic guide columns 15 are contacted with the middle plate 2. And the whole working process is finished until the longitudinal extrusion device is restored to the designated position.

The rubber sleeve clamp can continuously produce assembled products under the driving of the machine.
