[0002] The cold forging stamping part is a metal part manufactured by cold forging stamping process.

[0003] After the production of the cold forging stamping part, the stamping part needs to be detected. In order to avoid displacement of the stamping part during detection, a clamping fixture is used. For example, in the prior art, the patent application with the publication number CN 216577486 U installs a rotary drive device at the middle position inside the fixture table. The top end of the rotary drive device is fixedly connected with a screw rod. The outer part of the screw rod is movably connected with a fixture table. The top end of the screw rod is fixedly connected with a workbench. The utility model installs a bidirectional rotary drive device at the middle position of one side inside the workbench. The bidirectional rotary drive device can drive the screw rod to rotate, and at the same time, the screw thread sleeve on the screw rod drives the upper fixed arm to move. At the same time, the movement of the fixed arms on both sides of the upper part can complete the limiting of different size accessories. At the same time, by rotating the movable bolt on one side of the fixed arm, the movable bolt can push the limiting plate below through the movable shaft, so that the limiting plate is tightly attached to the surface of the accessory, and the stable clamping of the accessory is completed.

[0004] When the stamping part is detected, the effect of different surfaces is different. Therefore, after the detection of one surface is completed, the other surface also needs to be detected. However, when the other surface is detected after the detection of one surface is completed, the stamping part needs to be taken down and clamped again, which not only increases the operation steps, but also reduces the detection efficiency.

[0005] Therefore, it is necessary to provide a clamping fixture for cold forging stamping part to solve the above technical problems. UTILITY MODEL CONTENTS

[0027] A fixed seat 2 is fixedly installed at the middle position of the top of the base plate 1, a double-headed motor 21 is fixedly installed in the inside of the fixed seat 2, rotating rods 22 are fixedly installed at the two output ends of the double-headed motor 21, limit grooves 23 are formed in the two sides of the rotating rods 22;

[0028] Two support plates 3 are respectively screw-connected to the two ends of the outer side face of the double-headed threaded rod 13, rotating shafts 31 are rotatably connected to the inside of the top of the two support plates 3, clamping frames 32 are fixedly installed at one end of the rotating shafts 31, driving telescopic pieces 34 are fixedly installed at the top of the clamping frames 32, clamping plates 33 are fixedly installed at the moving end of the driving telescopic pieces 34, driven pulleys 35 are fixedly installed at the other end of the rotating shafts 31, belts 36 are sleeved on the outer side face of the driven pulleys 35, driving pulleys 37 are sleeved on the inner side face of the belts 36, rotating tubes 38 are fixedly installed in the inside of the driving pulleys 37, limit blocks 39 are fixedly installed on the two sides of the inner side face of the rotating tubes 38.

[0029] One end of the rotating rod 22 is arranged on the inner side face of the rotating tube 38, and the limit blocks 39 are slidably connected to the inner side face of the limit grooves 23.

[0030] When in use, the limit blocks 39 slide on the inner side face of the limit grooves 23, so that the rotating tube 38 can be driven to rotate when the rotating rod 22 rotates, and the rotating tube 38 can also slide on the outer side face of the rotating rod 22.

[0031] One end of the double-headed threaded rod 13 is rotatably connected to one end of the inner side face of the sliding groove 11.

[0032] The two sides of the support plate 3 are respectively attached to the two sides of the inner side face of the sliding groove 11.

[0034] The clamping plate 33 is arranged on the inner side face of the clamping frame 32.

[0035] The working principle of the clamping fixture for cold forging stamping parts is as follows:

[0036] In use, the stamping is placed between the two clamping frames 32, and then the drive motor 12 is started to drive the two-way threaded rod 13 to screw in the two support plates 3, so that the two support plates 3 move towards the middle until the two clamping frames 32 are on the outside of the stamping, and then the drive telescopic part 34 is started to extend to drive the clamping plate 33 to move downwards, thereby clamping and limiting the stamping. At this time, one side of the stamping is detected. When the other side of another stamping needs to be detected, the double-head motor 21 is started to drive the two rotating rods 22 to rotate, thereby driving the rotating tube 38 to rotate through the driving pulley 37, the belt 36 and the driven pulley 35, and then driving the rotating shaft 31 to rotate through the rotating tube 38, thereby driving the clamping frame 32 to rotate, so that the stamping is rotated to facilitate detection of the other side.

[0038] Through the cooperation of the double-head motor 21, the rotating rod 22, the limiting groove 23, the rotating tube 38, the driving pulley 37, the belt 36 and the driven pulley 35, etc., in use, the double-head motor 21 is started to drive the rotating rod 22 to rotate, and then the rotating rod 22 drives the rotating tube 38 and the driving pulley 37 to rotate, and then the belt 36, the driven pulley 35 and the rotating shaft 31 drive the clamping frame 32 to rotate, thereby driving the stamping to rotate. In this way, the stamping does not need to be disassembled and re-clamped by the staff, which not only reduces the operation steps, but also increases the detection efficiency of the stamping.

[0042] The spring 41 is fixedly installed at both ends of the top of the limiting plate 42.

[0043] The working principle of the clamping fixture for cold forging stamping parts is as follows:

[0044] When in use, the stamping part is placed on the inner side of the clamping frame 32, then the driving telescopic part 34 is started to drive the extension of the driving telescopic part 34, the fixed frame 4 is driven to move downwards, the bottom of the rubber pad 44 abuts against the top of the stamping part, at this time, the spring 41 is contracted, thereby reducing the pressing pressure.
