Description

Technical Field

[0001] The utility model relates to a wheel clamping device for vehicle detection. Background Art

[0002] When testing a vehicle, it is sometimes necessary to use a clamping device to clamp the non-driving wheel of the vehicle. Existing clamping devices include: Patent No. "CN 219007801U, a tire fixer for vehicle testing" and "CN213106441U, a motorcycle clamp", etc. The working process is as follows: Figure 4 As shown ( Figure 4 It is the patent CN 219007801U Figure 2 ) After the wheel drives onto the pressure plate, the servo motor drives the two clamping plates to clamp the wheel through the bidirectional threaded rod. Generally, the wheel cannot accurately drive to the exact center of the pressure plate. If the wheel is not in the exact center of the pressure plate, one of the two synchronously moving clamping plates will contact the wheel first and push the wheel to move horizontally to the other clamping plate. In this case, the load on the clamping plate that pushes the wheel to move will be very high, which can easily overload the lead screw and servo motor, making the fixture easily damaged and having a short service life. Utility Model Content

[0003] The utility model aims to provide a wheel clamping device for vehicle detection, which is used to solve the problems that the existing wheel clamping device is often overloaded and has a short service life.

[0004] In order to solve the above problems, the technical solution of the utility model is:

[0005] A wheel clamping device for vehicle inspection comprises a shell, an opening is provided on the shell, a support plate is fixedly connected in the opening, clamping rods are provided on both sides of the support plate, and multiple groups of driving mechanisms are provided in the shell, the driving mechanism comprises a first guide rod fixedly connected in the shell, two first guide sleeves are mounted on the first guide rod, the two first guide sleeves are fixedly connected to the two clamping rods respectively through a bent rod, two cylinders are provided under the first guide rod, the two cylinders are fixedly connected together back to back, and the two cylinder piston rods are respectively connected to the two first guide sleeves through supports.

[0006] The driving mechanism also includes a self-adjusting device, which includes a second guide rod fixedly connected to the shell, two positioning sleeves and two springs are arranged on the second guide rod, a second guide sleeve is fixedly connected to the cylinder sleeve, the second guide sleeve is arranged on the second guide rod, and two ends of the spring are respectively against the second guide sleeve and the positioning sleeve.

[0007] A top screw is threadedly connected to the positioning sleeve.

[0008] The opposite end surfaces of the two clamping rods are arc-shaped surfaces, and rubber sheets are fixedly connected to the arc-shaped surfaces of the clamping rods.

[0009] The beneficial effects of the utility model are as follows: after the vehicle tire drives onto the pallet, two cylinders drive two clamping rods to clamp the wheel. During the clamping process, the cylinder can automatically adjust its position to align with the tire position, thereby playing a self-regulating role, thereby effectively overcoming the overload problem and extending the service life of the wheel clamping device. At the same time, the structural design of the device is simple and reasonable, and is suitable for promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] A wheel clamping device for vehicle inspection comprises a shell 1, wherein the shell 1 is provided with an opening, a support plate 5 is fixedly connected in the opening, clamping rods 3 are provided on both sides of the support plate 5, the clamping rods 3 are located in the gap between the support plate 5 and the top surface of the shell 1, in order to enhance the strength of the support plate 5, a plurality of channel steels are welded in the shell 1 below the support plate 5 to support it, a plurality of driving mechanisms are provided in the shell 1, the driving mechanisms comprise a first guide rod 6 fixedly connected in the shell, two first guide sleeves 7 are mounted on the first guide rod 6, the two first guide sleeves 7 are fixedly connected to the two clamping rods 3 respectively through an L-shaped curved rod 2, two cylinders 13 are provided below the first guide rod 6, the two cylinders 13 are fixedly connected together back to back, and the piston rods of the two cylinders 13 are respectively connected to the two first guide sleeves 7 through supports.

[0018] The working process of the utility model is as follows: after the vehicle drives onto the support plate 5, the piston rods of each cylinder 13 retract at the same time, for example: the right clamping rod 3 first abuts against the vehicle tire, and as the right cylinder 13 continues to retract, the right cylinder 13 pulls the left cylinder 13 to move along the first guide rod 6 toward the center of the tire until the left clamping rod 3 also abuts against the vehicle tire, and finally the two cylinders 13 drive the two clamping rods 3 to clamp and fix the vehicle wheel at the same time; it can be seen that when the two cylinders 13 in the clamping device drive the two clamping rods 3 to clamp the wheel, the cylinder 13 can automatically adjust its position to align with the tire position, thereby playing a self-regulating role.

[0019] The driving mechanism also includes a self-adjusting device, which includes a second guide rod 8 fixedly connected to the shell, two positioning sleeves 9 and two springs 11 are provided on the second guide rod 8, a second guide sleeve 12 is fixedly connected to the cylinder sleeve of the cylinder 13, the second guide sleeve 12 is assembled on the second guide rod 8, and the two ends of the spring 11 are respectively against the second guide sleeve 12 and the positioning sleeve 9.

[0020] When the vehicle tire needs to leave the support plate 5, the piston rods of the two cylinders 13 extend to drive the two clamping rods 3 to loosen the vehicle tire. After loosening, the two clamping rods 3 are no longer in the initial positions at both ends of the clamping plate. At this time, workers need to use their feet to push them to the initial positions, which is more troublesome to operate. Therefore, a self-adjusting device is set. The working process of the self-adjusting device is that when the two clamping rods 3 are not in the initial positions of the support plate 5, the two springs 11 in the self-adjusting device automatically push the two cylinders 13 to move to push the two clamping rods 3 to the initial positions at both ends of the support plate 5.

[0021] A top screw 10 is threadedly connected to the positioning sleeve 9. This structure facilitates the adjustment of the elastic force of the spring 11 to achieve fine adjustment of the initial positions of the two pressure rods.

[0022] The opposite end faces of the two clamping rods 3 are arc-shaped surfaces, and a rubber sheet 4 is fixedly connected to the arc-shaped surfaces of the clamping rods 3. This structure can expand the contact surface and friction between the clamping rods 3 and the tire, and increase the fixing effect of the tire.

[0023] The contents described in the embodiments of this specification are merely an enumeration of the implementation forms of the utility model concept. The protection scope of the utility model should not be deemed to be limited to the specific forms described in the embodiments. The protection scope of the utility model also extends to equivalent technical means that can be thought of by those skilled in the art based on the concept of the utility model.
