At the same time, if the gripping force of the fixture is too large, it may cause damage to the injection molded part.

[0004] To address the aforementioned issues, a clamping mechanism for injection molded parts is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a gripping mechanism for injection molded parts, which solves the problem that the gripping mechanism of existing robots in the background art is usually a two-piece gripper. Two-piece grippers are difficult to prevent parts from slipping or shifting during the handling process, and if the gripping force of the clamp is too large, it may cause damage to the injection molded parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping mechanism for injection molded parts, including a fixing mechanism, a driving mechanism slidably disposed on both sides of the fixing mechanism, a gripper mechanism rotatably connected to one side of the driving mechanism, the fixing mechanism including a fixing plate, the driving mechanism including a driving cylinder fixedly disposed at the lower end of the fixing plate, a sliding member connected to the output end of the driving cylinder, the sliding member slidably disposed within the fixing plate, a connecting rod slidably sleeved in the sliding member, a connecting member fixedly disposed at the lower end of the fixing plate, the gripper mechanism including a movable frame rotatably connected to one side of the connecting member, the connecting rod inserted into the movable frame, a spring member disposed at the lower end of the movable frame, a gripper member rotatably disposed on one side of the movable frame, the spring member and one side of the gripper member being in contact.

[0007] Preferably, the fixing mechanism further includes a U-shaped connecting frame fixedly disposed at the upper center of the fixing plate, and the fixing plate has sliding grooves on both sides, with the sliding member slidably disposed inside the sliding grooves.

[0008] Preferably, the sliding member has a sliding groove for slidingly connecting the connecting rod, and the sliding groove is opened obliquely along the sliding member.

[0009] Preferably, the slider has a weight-reducing hole at its center.

[0010] Preferably, two sets of limiting rings are fixedly provided on the sleeve rod, and the limiting rings are arranged on both sides of the sliding member.

[0011] Preferably, the movable frame has a rotating slot for aligning with the gripper, and the lower end of the movable frame has a spring slot for aligning with the gripper.

[0012] Preferably, springs are provided on both sides of the movable frame, and the two sets of springs are used to balance the buffering pressure of the gripper.

[0013] Preferably, one side of the gripper is configured as a rotating block, which is rotatably engaged in a rotating slot, and one side of the gripper is configured as an interleaved claw, wherein the positions of the interleaved claws in the two sets of grippers are interleaved.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

The sleeve rod 23 is inserted into the moving frame 31, a spring member 32 is arranged at the lower end of the moving frame 31, and a gripper member 33 is rotatably arranged on one side of the moving frame 31. The spring member 32 and one side of the gripper member 33 are in contact.

[0027] Specifically, the fixed plate 11 and the drive cylinder 21 are fixedly arranged together. Two sets of sliding parts 22 are connected to the output ends on both sides of the drive cylinder 21. The sleeve rod 23 is slidably sleeved in the sliding part 22. The connecting part 24 is fixedly arranged. The drive cylinder 21 drives the sleeve rod 23, so that the moving frame 31 can rotate along the contact point with the connecting part 24 to realize clamping adjustment. The spring part 32 between the moving frame 31 and the gripper 33 increases the buffer force and prevents damage to the injection molded part. In addition, when the gripper 33 on both sides is closed, the teeth are interlaced, so that when the gripper 33 is closed, there is a bottom support, which can ensure that the injection molded part does not slip during the handling process.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1:

[0030] Combination Figures 2-5 The fixing mechanism 1 also includes a U-shaped connecting frame 12 fixedly disposed at the upper center of the fixing plate 11. The fixing plate 11 has sliding grooves 111 on both sides. The sliding member 22 is slidably disposed inside the sliding groove 111. The U-shaped connecting frame 12 realizes the external fixing of the gripping mechanism. The sliding groove 111 provides sliding guidance for the sliding member 22, realizing horizontal displacement on both sides.

[0031] The sliding member 22 is provided with a sliding groove 221 for slidingly connecting the connecting rod 23. The sliding groove 221 is opened obliquely along the sliding member 22. The opening of the sliding groove 221 facilitates the sliding adjustment of the rotation angle of the moving frame 31 by the connecting rod 23.

[0032] The sliding member 22 has a weight reduction hole 222 at its center. The weight reduction hole 222 reduces the weight of the fixture and reduces the driving pressure of the driving cylinder 21.

[0033] Two sets of limiting rings 231 are fixedly installed on the sleeve rod 23. The limiting rings 231 are located on both sides of the sliding member 22, and the limiting rings 231 realize the limiting and fixing of the gripper mechanism 3.

[0035] Combination Figure 4 and Figure 6 The movable frame 31 is provided with a rotating slot 311 aligned with the gripper 33, and the lower end of the movable frame 31 is provided with a spring slot 312 aligned with the gripper 33. The rotating slot 311 is used to rotate and engage the gripper 33, and the spring slot 312 is used to connect the spring 32.

[0036] Springs 32 are provided on both sides of the movable frame 31. The two sets of springs 32 are used to balance the buffering pressure of the gripper 33 and to provide buffering elastic force.

[0037] One side of the gripper 33 is configured as a rotating block 331, which is rotatably engaged in the rotating slot 311. The other side of the gripper 33 is configured as an interleaved claw 332. The positions of the interleaved claws 332 in the two sets of grippers 33 are interleaved. The connection between the rotating block 331 and the rotating slot 311 enables the gripper 33 to be positioned and rotated. The interleaved arrangement of the interleaved claws 332 ensures the stability of the gripper and reduces the gripper's fixed range.
