DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0024] A hole position detection device for a suspension bracket includes a detection table 2, on which a positioning component is provided to cooperate with the suspension bracket 1. Figure 3 As shown, the positioning assembly includes two first positioning blocks 201 arranged oppositely, two second positioning blocks 202 arranged oppositely, and two third positioning blocks 203 cooperating with the drilling position of the suspension bracket 1. The test platform 2 is also provided with a fixed seat 3, and a pressure rod 4 is rotatably installed on the top of the fixed seat 3. The test platform 2 is provided with a lifting mechanism for driving the pressure rod 4 to rotate, and a reset member 6 is provided between the pressure rod 4 and the test platform 2. The lifting mechanism drives the pressure rod 4 to rotate and rise away from the end of the suspension bracket 1, so that the end close to the suspension bracket 1 is pressed down synchronously, so as to realize the compression of the suspension bracket 1 on the test platform 2, and prevent the suspension bracket 1 from moving up and down during the hole position detection. By setting the reset member 6, when the lifting mechanism is reset, the pressure rod 4 is reset, so that the test personnel can remove the suspension bracket 1 from the test platform 2 after the test is completed. On this basis, the test platform 2 is provided with a pin shaft, the diameter of which matches the hole of the suspension bracket 1. If the pin shaft can pass through the through hole on the suspension bracket, it means that the product is qualified, otherwise it is unqualified.

[0025] As one specific embodiment of the present utility model, the pressure rod 4 includes a first connecting rod 401 and a second connecting rod 402. The ends of the first connecting rod 401 and the second connecting rod 402 are integrally connected. The angle between the first connecting rod 401 and the second connecting rod 402 is an obtuse angle. A clamping piece 403 is provided at one end of the first connecting rod 401 away from the second connecting rod 402.

[0026] Combination Figure 4Specifically, the lifting mechanism includes a vertically arranged screw rod 501, a lifting block 502 that is sleeved on the screw rod 501, and a vertical rod 503 that is fixedly arranged on the top of the detection platform 2. A through hole is arranged on one side of the lifting block 502 to cooperate with the vertical rod 503. Bearings are respectively arranged at the upper and lower ends of the screw rod 501, and the bearing arranged at the bottom is embedded in the detection platform. The bearing arranged at the top is connected to the detection platform through the frame 507. The top of the detection platform 2 is embedded with a bearing to realize the rotatable installation of the screw rod 501 on the detection platform 2. At the same time, A driving component for driving the screw rod 501 to rotate is provided on the detection platform 2, and the control end of the driving component is connected to the control switch, and the control switch is set on the detection platform 2. The lifting block 502 is set at the end of the second connecting rod 402 away from the suspension bracket 1, and the outer wall of the lifting block 502 is matched with the end of the first connecting rod 401 to set an inclined surface. Here, the lifting block 502 is set into a truncated cone shape, and a mounting through hole matching the screw rod 501 is opened in the middle of the lifting block 502, and the diameter of the lifting block 502 increases from top to bottom, thereby forming an inclined surface.

[0027] In the utility model, the screw rod 501 cooperates with the lifting block 502 to form a screw rod. By setting a vertical rod 503 that penetrates the lifting block 502, the lifting block 502 is prevented from rotating synchronously when the screw rod 501 rotates. The screw rod 501 is driven to rotate by the driving assembly, and the lifting block 502 moves upward. The end of the pressure rod 4 abuts against the lifting block 502, and the side of the lifting block 502 abutting against the end of the pressure rod 4 is an inclined surface, so that the abutting end of the pressure rod 4 is rotated and lifted, and the other end of the pressure rod 4 presses down to fix the suspension bracket 1 on the detection platform 2. At the same time, the reset member 6 is configured as a compression spring and is arranged between the inclined plate 61 of the fixing seat 3 and the second connecting rod 402. When the driving assembly is reset, the compression spring is reset from the deformed state, driving the pressure rod 4 to reset.

[0028] As one specific embodiment of the utility model, the driving assembly includes a motor 506 fixedly arranged on the detection platform 2, a first gear 504 connected to the rotating shaft of the motor 506, and a second gear 505 meshing with the first gear 504, and the second gear 505 is fixedly sleeved on the screw rod 501. The motor 506 drives the first gear 504 to rotate, and drives the second gear 505 meshing with the first gear 504 to rotate, so as to realize the synchronous rotation of the screw rod 501. The control end of the motor 506 is electrically connected to the control switch, and the control switch is arranged on the front side of the detection platform 2 for the convenience of the operator.

[0029] As a preferred embodiment of the detection device of the utility model, the pressure rod 4 further includes a fixed shaft 407 and a sleeve 408. The fixed shaft 407 is fixedly arranged at one end of the second connecting rod 402 away from the suspension bracket 1, and the sleeve 408 is sleeved outside the fixed shaft 407. The fixed shaft 407 can be fixedly linked with the end of the second pressure rod 4 by a thread, and the sleeve 408 sleeved outside the fixed shaft 407 is rotatable. The second pressure rod abuts against the lifting block 502 through the sleeve 408. When the lifting block 502 moves up, the rotating sleeve 408 can reduce the friction with the lifting block 502.

[0030] For another preferred embodiment of the detection device of the utility model, refer to Figure 5 The pressing member 403 includes a screw rod 404 and a pressing block 405 fixedly arranged at the bottom end of the screw rod 404. A through hole is arranged at the end of the first connecting rod 401 to match the screw rod 404. Two upper and lower nuts 406 are arranged at the end of the first connecting rod 401 to match the screw rod 404. The distance between the pressing block 405 and the first connecting rod 401 can be adjusted by the positioning and fixing method of the screw rod 404 and the nut 406, and it is also convenient for disassembly and assembly.

[0031] In another preferred embodiment of the detection device of the utility model, the top of the detection platform 2 is equipped with a micro switch in cooperation with the suspension bracket 1, and the micro switch installation position 7 is set at a corresponding position on the front end of the suspension bracket on the detection platform, such as Figure 4 As shown, the micro switch is electrically connected to the controller, and at the same time, the control end of the motor 506 is electrically connected to the controller, and the controller is electrically connected to the control switch. When the suspension bracket 1 to be inspected is installed on the inspection platform 2, the micro switch will be triggered to send a signal to the controller that the suspension bracket 1 is installed in place. At the same time, the inspection personnel will send a signal to the controller to start the motor 506 through the control switch. When the controller receives the signals from the micro switch and the control switch, the motor 506 can rotate to drive the lifting block 502 to move upward.

[0032] The embodiments described above are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
