[0024] Specifically, a motor is fixedly installed in the fixed platform 2, and a gear 201 is fixedly connected to the output end of the motor so that the gear 201 can rotate on the upper surface of the fixed platform 2. Two racks 202 are meshed on the left and right sides of the gear 201 so that the gear 201 can drive the two racks 202 to move in opposite directions when rotating. The racks 202 are slidably connected to the fixed platform 2 so that the racks 202 will not separate from the gear 201 when moving. A clamping plate 203 is fixedly welded on the rack 202, and a placement plate 204 is fixedly welded on the side of the clamping plate 203. The bridge housing 1 is placed on the placement plate 204 so that the bridge housing 1 can be on a horizontal plane. When the two clamping plates 203 move relative to each other, the front and rear sides of the bridge housing 1 will be clamped in the middle for rotation. The fixing platform 2 is fixed with a limit plate 205 welded thereto, and the gear 201 and the rack 202 are located below the limit plate 205, so that the connection between the gear 201 and the rack 202 is protected.

A spring 7 is fixedly welded on the side of the connecting block 501, and the other end of the spring 7 is fixedly welded on the U-shaped block 401. Since the U-shaped block 401 is fixedly connected to the fixing seat 4, the connecting block 501, after the spring 7 is stretched,The spring 7 will pull the connecting block 501 back, so that the clamping column 403 will shrink inward to fix the object, and finally cooperate with the clamping plate 203 in the middle of the fixing platform 2 to fix the bridge housing 1 on the placement plate 204, so that the placement plate 204 will not move when the size is detected, thereby improving the accuracy of the detection data.

[0025] The working principle and use process of the utility model are as follows: first, the bridge housing 1 is placed on the placement plate 204. At this time, the bridge housing 1 is in a horizontal state, but it is easy to move after being disturbed. At this time, the motor in the fixed platform 2 can be started to control the gear 201 to rotate, driving the rack 202 and the clamping plate 203 to approach the direction of the bridge housing 1. Then the clamping plate 203 can fix the front and back of the bridge housing 1 on the placement plate 204, and then rotate the screw rod 301 to control the moving plate 3, the fixing seat 4 and the driving plate 5 to approach the left and right sides of the bridge housing 1, and rotate the handles 6 on the two connecting blocks 501 so that the three clamps The tightening column 403 is driven, so that the clamping column 403 expands outward. At this time, the left and right sides of the bridge shell 1 can enter the middle of the three clamping columns 403. When the left and right sides of the bridge shell 1 touch the driving plate 5, the handle 6 can be released to allow the spring 7 to pull the handle 6 back in the opposite direction, so that the three clamping columns 403 shrink inward, and then fix the left and right ends of the bridge shell 1, so that the bridge shell 1 can be completely fixed on the placement plate 204, which is convenient for the staff to perform dimensional detection of the bridge shell 1, making the dimensional detection more accurate, ensuring the reliability of the detection data, and improving product quality.
