Description

Technical Field

[0001] This utility model relates to the field of automotive parts clamping technology, and more specifically, to an automotive parts clamping device with no blind spots. Background Technology

[0002] Automotive parts require painting during production to protect them, improve their appearance, and enhance their performance. Currently, for painting automotive parts with ring-frame structures such as wheel hubs, an existing patent (publication number: CN222132319U) discloses a ring-frame-based, dead-angle-free painting device for automotive parts. This device includes a base plate, an adjustment mechanism on top of the base plate, a lifting mechanism on top of the base plate, and a control unit fixedly installed on top of the base plate. The adjustment mechanism includes a moving component and a spraying component, with the spraying component positioned on top of the moving component. This allows the paint head to perform comprehensive painting of the automotive parts located at the center of the ring frame, resulting in a wider and more uniform painting area. The position of the ring frame can be adjusted during painting, and the position of the sliding frame can be adjusted according to the length of the automotive parts, further expanding the painting area and achieving dead-angle-free painting. Adjusting the height of the part hook allows the automotive parts to be hung at the center of the ring frame, increasing the device's adaptability.

[0003] When the above-mentioned device is in use, the ring frame parts are suspended and clamped by hooks. Although multi-angle spraying can reduce the spraying dead angles, the hooks have poor stability for the ring frame and are easily shaken by the spraying force, resulting in uneven spraying and thus affecting the appearance quality and protective performance of the wheel hub surface. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a clamping device for auto parts without dead angles, so as to solve the problem that the hook has poor stability on the ring frame and is easily affected by the spray force, causing the ring frame to shake and resulting in uneven spraying.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a clamping device for auto parts without blind spots, including a hanging rod, a fixed box fixedly installed at the bottom of the hanging rod, a movable groove opened on the front side of the fixed box, two parallel clamping rollers arranged vertically on the front side of the fixed box, a clamping assembly arranged inside the fixed box, the clamping assembly being used to drive the two clamping rollers to move closer or further apart, and a rotating assembly arranged inside the fixed box, the rotating assembly being used to drive the two clamping rollers to rotate in the same direction, thereby driving the ring frame parts to rotate.

[0006] Preferably, the clamping assembly includes a counter-rotating threaded screw, which is rotatably connected to a fixed box. A guide rod and a drive motor are also fixedly installed in the fixed box. The output end of the drive motor is fixedly connected to one end of the counter-rotating threaded screw. Two slides corresponding to the clamping rollers are threadedly connected to the counter-rotating threaded screw, and the slides are slidably sleeved on the outer surface of the guide rod. A first pulley is rotatably connected to each of the two slides. A plug is provided at one end of the first pulley. An anti-detachment cap is fixedly connected to the end of the plug away from the first pulley. The plug is detachably inserted into the clamping roller and is located in a movable groove.

[0007] Preferably, the first pulley has a threaded groove at the end near the insertion rod, and the end of the insertion rod away from the anti-detachment cap is threaded into the threaded groove, wherein the anti-detachment cap is hexagonal in shape.

[0008] Preferably, the movable groove is provided with symmetrical flexible sealing strips.

[0009] Preferably, the rotating assembly includes an electric telescopic rod, which is fixedly installed on the inner wall of the fixed box. The output end of the electric telescopic rod is fixedly connected to a C-shaped bracket. The upper and lower sides of the C-shaped bracket are rotatably connected to second pulleys. The outer surfaces of the two second pulleys are fitted with transmission belts. A second drive motor is also fixedly installed on the C-shaped bracket. The output end of the second drive motor is rotatably connected to the rotating end of one of the second pulleys.

[0010] Preferably, the electric telescopic rod can drive the transmission belt to move towards the first pulley, the width of the transmission belt is smaller than the width of the first pulley, and the distance between the two second pulleys is greater than the maximum distance between the two first pulleys.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention involves bolting the top of the boom into the spraying equipment and placing the inner ring of the annular frame part onto the clamping rollers. The clamping assembly drives the two clamping rollers to separate and expand, which can stably fix the annular frame part from the inner ring before spraying it. This avoids the annular frame part from shaking during spraying, thus ensuring the uniformity of the spraying.

[0013] This invention uses a drive motor to drive a screw with opposite threads to rotate, which enables two slides to move vertically close to or away from each other along the surface of a guide rod. This allows the insert rod on the first pulley to drive the clamping rollers to clamp the parts. Furthermore, since the first pulley can rotate, it can prevent the clamping rollers from causing significant wear on the inner ring of the parts during the clamping process.

[0014] This invention allows the insert rod to be disassembled from the threaded groove by rotating the anti-detachment cap, thereby removing the clamping roller and cleaning it. The operation is simple and convenient, improving the overall practicality of the device.

[0015] This invention uses an electric telescopic rod to extend, bringing the transmission belt close to and pressing it against the surface of the first pulley. Then, a second drive motor drives the second pulley to rotate, and the friction of the transmission belt drives the clamping rollers on the first pulley to rotate synchronously and in the same direction, thereby driving the connecting ring to rotate and continuously changing the contact position between the clamping rollers and the parts. At this time, by aiming the spray gun at the inner ring of the parts and keeping it stationary, the inner side of the parts can be sprayed evenly and without dead angles. Attached Figure Description

[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0026] As attached Figure 1 To be continued Figure 7This utility model provides a clamping device for auto parts without blind spots, including a lifting rod 1, a fixed box 2 fixedly installed at the bottom of the lifting rod 1, a movable groove 3 opened on the front side of the fixed box 2, two parallel clamping rollers 4 also arranged on the front side of the fixed box 2 along the vertical direction, a clamping assembly 5 arranged inside the fixed box 2, the clamping assembly 5 is used to drive the two clamping rollers 4 to move close or far apart, and a rotating assembly 6 is also arranged inside the fixed box 2, the rotating assembly 6 is used to drive the two clamping rollers 4 to rotate in the same direction, thereby driving the ring frame parts to rotate.

[0027] Specifically, the top of the boom 1 is bolted into the spraying equipment, and the inner ring of the ring frame part is placed on the clamping roller 4. The clamping assembly 5 drives the two clamping rollers 4 to expand outwards, which can stably fix the ring frame part from the inner ring. Then, it is sprayed, which can prevent the ring frame part from shaking during spraying.

[0028] Preferably, the clamping assembly 5 includes a counter-rotating threaded screw 51, which is rotatably connected to the fixed box 2. The fixed box 2 also has a guide rod 52 and a drive motor 53 fixedly installed inside. The output end of the drive motor 53 is fixedly connected to one end of the counter-rotating threaded screw 51. Two slides 54, which correspond one-to-one with the clamping rollers 4, are threadedly connected to the counter-rotating threaded screw 51. The slides 54 are slidably sleeved on the outer surface of the guide rod 52. A first pulley 55 is rotatably connected to each of the two slides 54. A rod 57 is provided at one end of the first pulley 55. An anti-detachment cap 58 is fixedly connected to the end of the rod 57 away from the first pulley 55. The rod 57 is detachably inserted into the clamping roller 4 and is located in the movable groove 3.

[0029] Specifically, by driving the anti-directional threaded screw 51 to rotate through the drive motor 53, the two slides 54 can move vertically close to or far apart along the surface of the guide rod 52, so that the insert rod 57 on the first pulley 55 can drive the clamping roller 4 to clamp. Furthermore, since the first pulley 55 can rotate, it can avoid the clamping roller 4 from causing large wear on the inner ring of the part during the clamping process.

[0030] Preferably, the first pulley 55 has a threaded groove 56 at the end near the insertion rod 57, and the end of the insertion rod 57 away from the anti-detachment cap 58 is threaded into the threaded groove 56. The anti-detachment cap 58 is hexagonal in shape.

[0031] Specifically, after prolonged use, the anti-detachment cap 58 can be rotated using a wrench or other tools to disassemble the insert rod 57 from the threaded groove 56, thereby removing the clamping roller 4 and cleaning it. The operation is simple and convenient, improving the overall practicality of the device.

[0032] Preferably, the movable groove 3 is provided with symmetrical flexible sealing strips 7. During the spraying process, the flexible sealing strips 7 can ensure that the movable groove 3 is sealed, thereby preventing the paint from entering the fixed box 2 and causing damage to the internal structure of the fixed box 2.

[0033] Preferably, the rotating assembly 6 includes an electric telescopic rod 61, which is fixedly installed on the inner wall of the fixed box 2. The output end of the electric telescopic rod 61 is fixedly connected to a C-shaped bracket 62. The upper and lower sides of the C-shaped bracket 62 are rotatably connected to second pulleys 63. The outer surfaces of the two second pulleys 63 are fitted with transmission belts 64. A second drive motor 65 is also fixedly installed on the C-shaped bracket 62. The output end of the second drive motor 65 is rotatably connected to the rotating end of one of the second pulleys 63.

[0034] Preferably, the electric telescopic rod 61 can drive the transmission belt 64 to move toward the first pulley 55. The width of the transmission belt 64 is smaller than the width of the first pulley 55, and the distance between the two second pulleys 63 is greater than the maximum distance between the two first pulleys 55.

[0035] Specifically, after the clamping assembly 5 clamps and fixes the part, the electric telescopic rod 61 extends, causing the transmission belt 64 to come close to the surface of the first pulley 55. Then, the second pulley 63 is driven to rotate by the drive motor 65, and the friction of the transmission belt 64 drives the clamping roller 4 on the first pulley 55 to rotate synchronously and in the same direction, so as to drive the connecting ring to rotate and continuously change the contact position between the clamping roller 4 and the part. At this time, the spray gun is aimed at the inner ring of the part and kept still, so that the inner side of the part can be sprayed evenly and without dead angles.
