[0002] In the existing production process, manual labor is required to remove the brake shoes from the material frame, inspect the appearance of the brake shoes, and transport them. The number of brake shoes on the assembly line is large, requiring a large number of manual labor to coordinate and transport them.

[0009] a driving mechanism connected to the first clamping arm and the second clamping arm, the driving mechanism being configured to drive the first clamping arm and the second clamping arm toward or away from each other along a first direction;

[0010] The first clamping arm and the second clamping arm can approach each other along a first direction to clamp the protrusion.

[0011] In one embodiment, the driving mechanism adopts a bidirectional cylinder, one driving shaft of the bidirectional cylinder is connected to the first clamping arm, and the other driving shaft of the bidirectional cylinder is connected to the second clamping arm. The bidirectional cylinder drives the first clamping arm and the second clamping arm to move closer to or away from each other along the first direction through the extension and contraction of the two driving shafts.

[0012] In one embodiment, the first clamping arm comprises:

[0013] a first connecting block, one end of which is connected to a driving shaft of the bidirectional cylinder; and

[0014] a first clamping jaw, one end of which is connected to the other end of the first connecting block; and

[0015] a first limiting block, which is arranged at the other end of the first clamping jaw;

[0016] The other end of the first clamping jaw can contact with one side of the protrusion. When the other end of the first clamping jaw contacts with one side of the protrusion, the first limit block extends into the first through hole to prevent the brake shoe from rotating.

[0017] In one embodiment, the first through hole is adapted to the first limiting block.

[0018] In one embodiment, the first clamping jaw comprises:

[0019] A first clamping block, one end of which is provided with a first limiting block; and

[0020] A second clamping block, which is bent and connected to the other end of the first clamping block;

[0021] The first clamping block is connected to the second clamping block at a 90-degree angle. When the brake shoe clamp clamps the brake shoe, the second clamping block is placed on the fixed end of the bidirectional cylinder.

[0022] In one embodiment, the second clamping arm comprises:

[0023] a second connecting block, one end of which is connected to the other driving shaft of the bidirectional cylinder; and

[0026] The other end of the second clamping jaw can contact with one side of the protrusion. When the other end of the second clamping jaw contacts with one side of the protrusion, the second limit block extends into the second through hole to prevent the brake shoe from rotating.

[0033] A rotary cylinder, the rotary end of which is connected to the driving mechanism;

[0034] a fixed bracket on which the fixed end of the rotary cylinder is fixed;

[0035] Among them, the rotary cylinder is used to drive the driving mechanism to rotate to adjust the rotation position of the brake shoe.

[0036] In one embodiment, the driving mechanism includes two one-way driving cylinders arranged opposite to each other along a first direction, and the driving shafts of the two one-way driving cylinders are arranged in opposite directions, the driving shaft of one of the one-way driving cylinders is connected to the first clamping arm, and the driving shaft of the other one-way driving cylinder is connected to the second clamping arm.

[0037] Compared with the prior art, the advantage of the present invention is that a first clamping arm and a second clamping arm are provided, and the first clamping arm and the second clamping arm are brought close to each other to clamp and fix the brake shoe. At the same time, the first clamping arm partially extends into the first through hole, and the second clamping arm partially extends into the second through hole. This realizes the double limit function of the brake shoe. Thus, the clamping and anti-rotation function of the brake shoe clamp is realized. A driving mechanism is provided, which is used to drive the movement of the first clamping arm and the second clamping arm to achieve the clamping or loosening of the brake shoe. Thus, the mechanized clamping and fixing of the brake shoe is achieved. At the same time, the brake shoe clamp cooperates with an external manipulator to realize the mechanized handling of the brake shoe. This avoids the problem of complicated processes and low handling efficiency caused by the manual handling method used in the technology. In turn, the handling efficiency of the brake shoe is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The present invention will be further described below with reference to the accompanying drawings.

[0045] Example 1

[0046] like Figure 1 and Figure 3 As shown, the utility model provides a brake shoe clamp, the brake shoe 100 has a protrusion, and both sides of the protrusion are along the first direction ( Figure 1 A first through hole 101 and a second through hole are provided on the brake shoe clamp (in the horizontal direction). The brake shoe clamp includes a first clamping arm 10, a second clamping arm 20, and a driving mechanism 30. The first clamping arm 10 partially extends into the first through hole 101 to prevent the brake shoe 100 from rotating; the second clamping arm 20 is arranged opposite to the first clamping arm 10 in the first direction, and the second clamping arm 20 partially extends into the second through hole to prevent the brake shoe 100 from rotating; the driving mechanism 30 is connected to the first clamping arm 10 and the second clamping arm 20, and is used to drive the first clamping arm 10 and the second clamping arm 20 to move closer to or away from each other along the first direction; the first clamping arm 10 and the second clamping arm 20 can move closer to each other along the first direction to clamp the protrusion.

[0047] In the above arrangement, a first clamping arm 10 and a second clamping arm 20 are provided, and the first clamping arm 10 and the second clamping arm 20 are brought close to each other to clamp and secure the brake shoe 100. At the same time, the first clamping arm 10 partially extends into the first through-hole 101, and the second clamping arm 20 partially extends into the second through-hole. This achieves a dual position limit function for the brake shoe 100. This also realizes the clamping and anti-rotation function of the brake shoe clamp. A driving mechanism 30 is provided to drive the movement of the first clamping arm 10 and the second clamping arm 20 to achieve clamping or loosening of the brake shoe 100. This achieves mechanized clamping and fixing of the brake shoe 100. At the same time, the brake shoe clamp cooperates with an external manipulator to achieve mechanized handling of the brake shoe 100. This avoids the problems of complex processes and low handling efficiency caused by the manual handling method used in the prior art, thereby improving the handling efficiency of the brake shoe 100.

[0048] It should be noted that the brake shoe 100 on the assembly line is clamped and secured by a brake shoe clamp, and a robot can reach near the brake shoe clamp to move it away. After the robot clamps and secures the brake shoe 100, the brake shoe clamp needs to be released. This purely mechanical handling method can completely replace the existing manual handling method of brake shoes 100.

[0049] Specifically, if Figure 1 As shown, in one embodiment, the drive mechanism 30 utilizes a bidirectional cylinder. One drive shaft of the bidirectional cylinder is connected to the first clamping arm 10, and the other drive shaft of the bidirectional cylinder is connected to the second clamping arm 20. The bidirectional cylinder drives the first clamping arm 10 and the second clamping arm 20 toward or away from each other in a first direction by extending and retracting the two drive shafts. In this way, the bidirectional cylinder realizes the driving function of the drive mechanism 30.

[0050] Specifically, if Figure 1 As shown, in one embodiment, the first clamping arm 10 includes a first connecting block 11, a first clamping jaw 12, and a first stopper 13. The first connecting block 11 has one end connected to a drive shaft of a bidirectional cylinder; the first clamping jaw 12 has one end connected to the other end of the first connecting block 11; and the first stopper 13 is disposed at the other end of the first clamping jaw 12. The other end of the first clamping jaw 12 is capable of contacting one side of the protrusion. When the other end of the first clamping jaw 12 contacts one side of the protrusion, the first stopper 13 extends into the first through hole 101 to prevent the brake shoe from rotating.

[0051] Specifically, if Figure 1 As shown, in one embodiment, the first through hole 101 is adapted to the first limiting block 13 .

[0052] Specifically, if Figure 1 As shown, in one embodiment, the first through hole 101 is a square hole, and the first limiting block 13 is a square block.

[0053] Of course, according to actual conditions, the first through hole 101 can be configured as a triangular hole, and the corresponding first limiting block 13 can be configured as a triangular block. The first through hole 101 can also be configured as a hexagonal hole, and the corresponding first limiting block 13 can be configured as a hexagonal block.

[0054] Specifically, if Figure 2 As shown, in one embodiment, the first clamping jaw 12 includes a first clamping block 121 and a second clamping block 122. The first clamping block 121 has a first stopper 13 disposed on one end thereof; the second clamping block 122 is bent and connected to the other end of the first clamping block 121. The first clamping block 121 and the second clamping block 122 are connected at a 90-degree angle. When the brake shoe clamp clamps the brake shoe 100, the second clamping block 122 is placed on the fixed end of the bidirectional cylinder.

[0055] In this arrangement, when the brake shoe clamp clamps the brake shoe 100, the second clamping block 122 rests on the fixed end of the bidirectional cylinder. This allows the fixed end of the bidirectional cylinder to bear the majority of the weight of the brake shoe 100 and the first clamping arm 10. This prevents the entire weight of the brake shoe 100 and the first clamping arm 10 from being borne by the drive shaft of the bidirectional cylinder, thereby extending the service life of the bidirectional cylinder.

[0056] Specifically, if Figure 1 As shown, in one embodiment, the second clamping arm 20 includes a second connecting block 21, a second clamping jaw 22, and a second stopper 23. The second connecting block 21 has one end connected to the other drive shaft of the bidirectional cylinder; the second clamping jaw 22 has one end connected to the other end of the second connecting block 21; and the second stopper 23 is disposed at the other end of the second clamping jaw 22. The other end of the second clamping jaw 22 is capable of contacting one side of the protrusion. When the other end of the second clamping jaw 22 contacts one side of the protrusion, the second stopper 23 extends into the second through hole to prevent the brake shoe 100 from rotating.

[0057] Specifically, if Figure 1 As shown, in one embodiment, the second through hole is adapted to the second limiting block 23 .

[0058] Specifically, if Figure 1 As shown, in one embodiment, the second through hole is a square hole, and the second limiting block 23 is a square block.

[0059] Of course, according to actual conditions, the second through hole can be set as a triangular hole, and the corresponding second limiting block 23 can be set as a triangular block. The second through hole can also be set as a hexagonal hole, and the corresponding second limiting block 23 can be set as a hexagonal block.

[0060] Specifically, if Figure 2 As shown, in one embodiment, the second clamping jaw 22 includes a third clamping block 221 and a fourth clamping block 222. The third clamping block 221 has a second stopper 23 disposed on one end thereof, and the fourth clamping block 222 is bent and connected to the other end of the third clamping block 221. The third and fourth clamping blocks 221 and 222 are connected at a 90-degree angle. When the brake shoe clamp clamps the brake shoe 100, the fourth clamping block 222 is placed on the fixed end of the bidirectional cylinder.

[0061] In this arrangement, when the brake shoe clamp clamps the brake shoe 100, the fourth clamping block 222 rests on the fixed end of the bidirectional cylinder. This allows the fixed end of the bidirectional cylinder to bear most of the weight of the brake shoe 100 and the second clamping arm 20. This prevents the entire weight of the brake shoe 100 and the second clamping arm 20 from being borne by the drive shaft of the bidirectional cylinder, thereby extending the service life of the bidirectional cylinder.

[0062] Specifically, if Figure 1As shown, in one embodiment, the brake shoe fixture further includes a rotating cylinder 40 and a fixed bracket 50. The rotating end of the rotating cylinder 40 is connected to the driving mechanism 30; the fixed end of the rotating cylinder 40 is fixed to the fixed bracket 50. The rotating cylinder 40 is used to drive the driving mechanism 30 to rotate to adjust the rotational position of the brake shoe 100.

[0063] In the above arrangement, a rotating cylinder 40 is provided, which utilizes its rotational drive mechanism 30 and the first and second clamping arms on the drive mechanism 30 to adjust the rotational position of the brake shoe 100. This ensures that the brake shoe 100 can be rotated to the appropriate position for grasping by an external robot arm, thereby improving the handling efficiency of the brake shoe 100.

[0064] Specifically, in one embodiment, the brake shoe clamp further includes a control system, which is electrically connected to the drive mechanism 30 for controlling the movement of the first and second clamping arms, and is also electrically connected to the rotary cylinder 40 for controlling its rotation.

[0065] Example 2

[0066] The differences between the second embodiment and the first embodiment are as follows:

[0067] Specifically, in one embodiment, a portion of the first clamping arm 10 extends into the first through hole 101 to prevent the brake shoe 100 from rotating. The second clamping arm 20 does not extend into the second through hole.

[0068] Of course, according to actual conditions, a second clamping arm 20 can be provided, which is arranged opposite to the first clamping arm 10 in the first direction, and the second clamping arm 20 partially extends into the second through hole to prevent the brake shoe 100 from rotating. The first clamping arm 10 does not extend into the first through hole 101.

[0069] Specifically, in one embodiment, the driving mechanism 30 includes two unidirectional driving cylinders arranged opposite to each other along a first direction, and the driving shafts of the two unidirectional driving cylinders are arranged in opposite directions, the driving shaft of one of the unidirectional driving cylinders is connected to the first clamping arm 10, and the driving shaft of the other unidirectional driving cylinder is connected to the second clamping arm 20.

[0070] Specifically, in one embodiment, when the brake shoe clamp clamps the brake shoe, the first and second clamping jaws are not placed on the fixed end of the driving mechanism 30. The first and second clamping jaws are configured as a straight rod structure.

[0071] Specifically, in one embodiment, the first and second connecting blocks are not provided, and the first and second clamping jaws are directly connected to the driving shaft of the driving mechanism.

[0072] The other structures of the second embodiment are identical to those of the first embodiment, and will not be further described here.

[0073] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
