Description

Technical Field

[0001] This utility model relates to the field of wheel hub processing equipment technology, and more specifically to a clamping and rotating tooling for wheel hub grinding and polishing. Background Technology

[0002] In existing wheel hub manufacturing processes, the wheel hub blank is first made by casting, and then cooled and machined.

[0003] However, polishing is required, which is generally done first through automated mechanical polishing. For example, when polishing the outer wall of the rim at the outer end, due to the curvature requirements of the rim, the robotic arm needs to continuously tilt and return the hub to achieve the arc-shaped polishing. However, the existing hub clamping mechanism only needs the function of horizontal rotation and does not have a structure to tilt the hub. Since the existing polishing robotic arm cannot achieve tilting operation, this part can only be polished manually, with limited effect. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a clamping and rotating tool for wheel hub grinding and polishing. It can tilt and rotate the wheel hub so that the outer edge of the wheel can be used for existing grinding processes, thus ensuring the processing effect.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A clamping and rotating fixture for wheel hub grinding and polishing includes a base, a rotary servo motor is fixed in the middle of the bottom surface of the top plate of the base, and the top end of the output shaft of the rotary servo motor extends out of the top surface of the top plate of the base and is fixed with a horizontal rotating plate.

[0007] The top surface of the horizontal rotating plate is fixed with support plates on the left and right sides. The flipping frame is located between the two support plates and is movably connected to the two support plates through two hinge shafts. The bottom inner walls of the left and right side plates of the flipping frame are fixed with inner transmission plates. The bottom surface of the inner transmission plate is an arc-shaped wall with teeth formed on it. The top surface of the horizontal rotating plate below it is equipped with racks that extend back and forth. The teeth and racks cooperate and correspond.

Connecting blocks are fixed on the rear of the opposite walls of the two racks. The transverse beam is fixed on the two connecting blocks. A connecting plate is fixed on the top surface of the middle of the rear of the horizontal rotating plate. The rear of the electric cylinder is fixed on the connecting plate. The front end of the push rod of the electric cylinder is fixed in the middle of the transverse beam.

[0010] The top surface of the top plate of the flipping frame is fixed with an upper horizontal guide plate. Multiple outer end fixing plates are fixed with the top surface of the edge of the upper horizontal guide plate. The screw part of the adjusting bolt is screwed into the middle screwing through hole of the corresponding outer end fixing plate. The inner end of the screw part of the adjusting bolt extends out of the inner side wall of the corresponding outer end fixing plate and is movably connected to an end limiting plate. The inner end face of the end limiting plate is close to the outer side wall of the bottom of the hub placed in the middle of the top surface of the upper horizontal guide plate.

A clamping cylinder is fixed in the middle of the bottom surface of the top plate of the flipping frame. The top of the push rod of the clamping cylinder extends out of the top surface of the top plate of the flipping frame and the top surface of the middle through hole of the upper horizontal guide plate and is fixed with a conical push block. The outer side wall of the conical push block is a conical wall with a small outer diameter at the top and a large outer diameter at the bottom, which is in close contact with the inner side wall of all sector-shaped blocks.

[0012] A wear-resistant layer is fixed to the upper part of the outer side wall of the fan-shaped block, which presses against the corresponding wall surface of the inner side wall of the hub.

[0026] Furthermore, the top surface of the top plate of the flipping frame 20 is fixed with an upper horizontal guide plate 22, and the top surface of the edge of the upper horizontal guide plate 22 is fixed with multiple outer end fixing plates 23. The screw part of the adjusting bolt 24 is screwed into the middle screwing through hole of the corresponding outer end fixing plate 23. The inner end of the screw part of the adjusting bolt 24 extends out of the inner side wall of the corresponding outer end fixing plate 23 and is movably connected to an end limiting plate 25. The inner end face of the end limiting plate 25 is close to the outer side wall of the bottom of the hub 100 placed in the middle of the top surface of the upper horizontal guide plate 22.

[0027] Furthermore, a locking nut 26 is screwed onto the screw portion of the adjusting bolt 24, and the end face of the locking nut 26 presses against the end face of the corresponding outer end fixing plate 23. A guide rod 231 is fixed on the outer side wall of the end limiting plate 25, and the guide rod 231 is inserted into the guide through hole of the corresponding outer end fixing plate 23.

[0028] Furthermore, multiple sector-shaped blocks 30 are placed on the top surface of the upper horizontal guide plate 22, forming a circle. The upper part of the outer side wall of each sector-shaped block 30 is a conical wall, and the inner side wall of each sector-shaped block 30 is a conical wall. A guide block 31 is fixed to the bottom surface of each sector-shaped block 30. The guide block 31 is inserted into the elongated groove 221 formed on the edge of the top surface of the upper horizontal guide plate 22 and cooperates with the elongated groove 221. A clamping cylinder 260 is fixed in the middle of the bottom surface of the top plate of the flipping frame 20. The top end of the push rod of the clamping cylinder 260 extends out of the top surface of the top plate of the flipping frame 20 and the top surface of the middle through hole of the upper horizontal guide plate 22 and is fixed with a conical push block 3. The outer side wall of the conical push block 3 is a conical wall with a small outer diameter at the top and a large outer diameter at the bottom, and it is in close contact with the inner side wall of each sector-shaped block 30. The clamping cylinder 260 is connected to the solenoid valve of the hydraulic system via a connecting pipe. Its hydraulic system is a conventional structure and will not be described in detail here.

[0029] Furthermore, a wear-resistant layer 310 is fixed to the upper part of the outer side wall of the sector block 30, which presses against the corresponding wall surface of the inner side wall of the hub 100.

[0031] Furthermore, a transverse sensing plate 4 is fixed to the right side wall of the horizontal rotating plate 12, and a fixing plate is fixed to one side of the top surface of the corresponding base 10. A slotted photoelectric sensor 5 is fixed to the fixing plate, and the transverse sensing plate 4 corresponds to the sensing slot of the slotted photoelectric sensor 5. In use, after the horizontal rotating plate 12 rotates one revolution, the transverse sensing plate 4 moves to the sensing slot of the slotted photoelectric sensor 5, indicating that it has rotated one revolution. At this time, the slotted photoelectric sensor 5 transmits the sensing signal to the control host, and the control host controls the rotation servo motor 11 to stop running. Then, it runs in the opposite direction, causing the horizontal rotating plate 12 to rotate one revolution in the opposite direction. This alternating rotation is repeated in this manner.

[0032] In this embodiment, all electrical components are electrically connected to the control host via electrical connection lines and are controlled by the control host. This is a conventional structure and will not be described in detail here.

[0033] In this embodiment, the base 10 can be fixed below the grinding robot. The grinding robot has a conventional structure that can move left and right, forward and backward, and up and down.

[0034] The position of the end limiting plates 25 can be changed by loosening the locking nut 26 and rotating the adjusting bolt 24, so that the inner end face of all the end limiting plates 25 is aligned with the outer side wall of the bottom of the wheel hub 100 to be installed. Then, the locking nut 26 is tightened. The wheel hub 100 is then placed on the top surface of the upper horizontal guide plate 22, so that the outer side wall of its bottom is close to the inner end face of the corresponding end limiting plate 25. Then, the push rod of the pressing cylinder 260 is pushed to lift the conical pushing block 3, pressing all the wear-resistant layers 310 against the inner side wall of the wheel hub 100. On the corresponding wall surface, it is pressed and fixed. Then, by running the rotary servo motor 11, the hub 100 can be rotated horizontally. By pushing or retracting the push rod of the electric cylinder 15, the hub 100 can be rotated and tilted, so that the outer rim at its outer end can be tilted and its angle changed. This allows it to perform arc-shaped grinding with the grinding component of the grinding robot (in this embodiment, a grinding rod is used, which is always rotating during operation) to meet the processing needs. It is easy to adjust, has good performance, and can also be used for manual grinding and other operations, with a wide range of applications.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
