Description

Technical Field

[0001] The utility model relates to the technical field of wheel cover processing, in particular to a wheel cover multi-station milling inner support turning device. Background Art

[0002] The wheel cover is also called the wheel cover or hub cover. The drive shaft is connected to the wheel hub and is fastened by a large screw. Some cars will have a clip on the screw to prevent the screw from moving, and a cover will be put on the outside. This cover is the hub cover, which can prevent the large screw from rust and waterproof, because water will not easily corrode the screw. During the processing of the wheel cover, a flipping device is needed to fix it so that the milling machine can mill the wheel cover. However, the existing clamping and fixing devices are mostly clamped and fixed from the outside to the inside, which occupies a large space. Therefore, we have introduced a multi-station milling inner support flipping device for wheel covers.

[0003] The existing patent (publication number: CN213438496U) discloses a multi-angle flipping mechanism for a mold frame of a car hub cover that can be clamped at multiple angles, comprising a body and a return spring, a base is provided at the bottom end of the body, and a first flipping circle is distributed on the upper end of one side of the base, a connecting shaft is provided at the connection between the first flipping circle and the base, and a second flipping circle is distributed on the other side of the first flipping circle, a clamping mechanism is provided on the inner walls of the upper and lower sides of the first flipping circle, a transmission mechanism is provided at one end of the inner side of the base, and a first driven shaft is provided at the other end of the inner side of the base, the multi-angle flipping mechanism for the mold frame of the car hub cover that can be clamped at multiple angles is provided with a connecting shaft, four connecting shafts are provided, and the connecting shaft is fixedly connected with the rotating shaft. Since the first flipping circle forms a rotating structure with the body through the connecting shaft, when the rotating shaft rotates, the connecting shaft and the first flipping circle are driven to rotate synchronously, so as to process the car hub cover. In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. Most of the existing clamping and fixing devices clamp and fix from the outside to the inside, which occupies a large space; 2. When clamping the wheel cover, the existing equipment needs to manually rotate the handle to drive the bolts and the clamping block to fix the wheel cover, and the fixing speed is slow and inefficient.

[0007] Further preferably, the internal support assembly includes a top plate fixedly connected to the bottom of the flip arm, the bottom of the top plate is fixedly connected to the top ends of the three connecting columns, and a bottom plate is fixedly connected between the bottom ends of the three connecting columns, three sliding grooves are opened in the middle of the bottom plate, and sliders are slidably connected in the middle of the three sliding grooves, the side of the slider close to the bottom plate is fixedly connected to one end of the connecting rod, and the other end of the connecting rod is fixedly connected to the inner support bar, the top of the slider is fixedly connected to a vertical rod, the vertical rod is slidably connected to the inside of the arc groove, the arc groove is opened in the middle of the worm wheel, a worm is meshed on one side of the worm wheel, and one end of the worm is fixedly connected to the output end of the motor.

[0008] Further preferably, the number of the inner support bars is three, and the three inner support bars are equiangularly distributed on the outer side of the bottom plate, and the three inner support bars are all arc-shaped structures.

[0012] In the utility model, the worm is driven to rotate by a motor, and the rotation of the worm will drive the worm wheel to rotate. At this time, the arc groove on the worm wheel will also rotate synchronously, so that the vertical rod in the arc groove moves. However, since the slider at the bottom end of the vertical rod is limited by the slide groove, the vertical rod can only drive the slider to move in a straight line along the slide groove, thereby driving the three inner support bars on the outside to support and clamp the wheel cover. The inner support assembly adopts a motor, a worm wheel and a worm, which can drive the three inner support bars at the same time to quickly support the inner wall of the wheel cover. Compared with traditional manual clamping, it is faster and the efficiency is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In this embodiment, Figure 1 and Figure 2As shown, the flip assembly 3 includes a cylinder 301 fixedly connected to the top right side of the workbench 1, the top of the cylinder 301 is fixedly connected to a lifting block 302, the middle of the lifting block 302 is rotatably connected to a first connecting shaft 303, one end of the first connecting shaft 303 is fixedly connected to a gear 304, one side of the gear 304 is meshed with a rack 305, the end of the first connecting shaft 303 away from the gear 304 is fixedly connected to a flip arm 306, and two guide rods 307 are passed through the lifting block 302 in the vertical direction.

[0022] In this embodiment, Figure 1 As shown, the two guide rods 307 are parallel to each other, and the lifting block 302 forms a sliding limit structure through the two guide rods 307. The stroke of the cylinder 301 at the bottom of the lifting block 302 is consistent with the stroke of the rack 305, and the stroke of the rack 305 is half of the circumference of the gear 304; the guide rod 307 can limit the lifting block 302 to ensure the stability of the lifting block 302 when it is lifted and lowered, and when the output end of the cylinder 301 is fully extended, the gear 304 is engaged and rotated 180° along the rack 305, and the flip arm 306 is flipped 180°, which is convenient for processing the bottom of the wheel cover 5.

[0023] In this embodiment, Figure 3 , Figure 4 and Figure 5 As shown, the internal support assembly 4 includes a top plate 401 fixedly connected to the bottom of the flip arm 306, the bottom of the top plate 401 is fixedly connected to the top ends of the three connecting columns 402, and a bottom plate 403 is fixedly connected between the bottom ends of the three connecting columns 402, three sliding grooves 404 are opened in the middle of the bottom plate 403, and the middle parts of the three sliding grooves 404 are all slidably connected with sliders 405, the side of the slider 405 close to the bottom plate 403 is fixedly connected to one end of the connecting rod 406, and the other end of the connecting rod 406 is fixedly connected to the inner support bar 407, the top of the slider 405 is fixedly connected to a vertical rod 408, the vertical rod 408 is slidably connected to the inside of the arc groove 409, the arc groove 409 is opened in the middle of the worm gear 4010, a worm 4011 is meshed on one side of the worm gear 4010, and one end of the worm 4011 is fixedly connected to the output end of the motor 4012.

[0024] In this embodiment, Figure 3 , Figure 4 and Figure 5 As shown, there are three inner support bars 407, and the three inner support bars 407 are equiangularly distributed on the outer side of the bottom plate 403, and the three inner support bars 407 are all arc-shaped structures; the inner support bars 407 with an arc-shaped structure can better fit the inner wall of the wheel cover 5, thereby increasing the contact area with the wheel cover 5, increasing the friction force, and having a better inner support clamping effect on the wheel cover 5. Compared with the traditional external clamping mechanism, the internal support clamping mechanism saves more space.

[0025] In this embodiment, Figure 3 , Figure 4 and Figure 5 As shown, the worm wheel 4010 is connected to the base plate 403 by a second connecting shaft 4013, and the central axis of the second connecting shaft 4013 coincides with the central axis of the worm wheel 4010 and the base plate 403; so that the worm wheel 4010 can be supported and rotated at the same time, thereby driving the three arc grooves 409 to rotate, so that the vertical rod 408 in the arc groove 409 moves, but because the slider 405 at the bottom end of the vertical rod 408 is limited by the slide groove 404, the vertical rod 408 can only drive the slider 405 to move linearly along the slide groove 404, thereby driving the three outer inner support bars 407 to internally support and clamp the wheel cover 5, and the inner support assembly 4 adopts the cooperation of the motor 4012, the worm wheel 4010 and the worm 4011, which can simultaneously drive the three inner support bars 407 to quickly support the inner wall of the wheel cover 5, which is faster than the traditional manual clamping and the efficiency is greatly improved.

[0026] The use method and advantages of the utility model: When the wheel cover multi-station milling inner support flip device is used, the working process is as follows:

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, first, the inner support component 4 is placed in the middle of the inner ring of the wheel cover 5 that needs to be processed, and the motor 4012 is started to drive the worm 4011 to rotate. The rotation of the worm 4011 will drive the worm wheel 4010 to rotate. At this time, the arc groove 409 on the worm wheel 4010 will also rotate synchronously, so that the vertical rod 408 in the arc groove 409 moves, but because the slider 405 at the bottom end of the vertical rod 408 is limited by the slide groove 404, the vertical rod 408 can only drive the slider 405 to move linearly along the slide groove 404, thereby driving the three outer inner support bars 407 to internally support and clamp the wheel cover 5, and the inner support component 4 adopts the cooperation of the motor 4012, the worm wheel 4010 and the worm 4011, which can simultaneously drive the three inner support bars 407 to quickly clamp the inner wall of the wheel cover 5 The support is faster and more efficient than traditional manual clamping. When one side of the wheel cover 5 is processed, the cylinder 301 is started to push the lifting block 302 up. At this time, the gear 304 will rotate along the rack 305 in meshing. Because the stroke of the rack 305 is half the circumference of the gear 304, the gear 304 only rotates 180° when the output end of the cylinder 301 is extended to the longest. The rotation of the gear 304 will synchronously drive the flip arm 306 connected to it to rotate 180°, and finally the entire inner support assembly 4 and the wheel cover 5 will be flipped 180° to facilitate the processing of the other side of the wheel cover 5. The inner support assembly 4 is used to fix the wheel cover 5 in an internal support manner. Compared with the traditional external clamping mechanism, the internal support clamping mechanism saves more space.
