Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub processing, in particular to a positioning pin correction device for wheel hub processing. Background Art

[0002] The existing machining pallet is generally equipped with a product processing positioning tool, which is equipped with positioning pins. The distance between all positioning pins and the central axis of the machining pallet must be equal. The existing method is to manually adjust the positioning tool to adjust the position of the positioning pins, and then use a vernier caliper to measure the distance between the positioning pins and the core seat. By measuring the positions of all positioning pins, this operation method is difficult and takes a long time to calibrate.

[0003] According to a publicly disclosed wheel hub processing platform positioning pin correction device (Announcement No.: CN214923809U), in the above application, when correcting the position of the positioning pin, the bolt is continuously turned to move the position of the correction block, and then the bolt is tightened to correct the position of the positioning pin. Although this method can adjust the position of the correction block, the frequent turning of the bolt is very inconvenient, and deviations are very likely to occur during the turning process, resulting in the operator needing to readjust the position of the correction block. Moreover, if the position of the correction block is manually adjusted too quickly, it is very easy to cause a large deviation between the position of the correction block and the positioning pin, thereby affecting the operator's correction of the positioning pin. To address this problem, we have proposed a positioning pin correction device for wheel hub processing. Utility Model Content

[0004] The purpose of the utility model is to provide a positioning pin correction device for wheel hub processing to solve the problems raised in the above background technology.

[0006] Preferably, the control assembly further includes an adjusting member, which includes a circular plate, which is penetrated by the threaded rod and fixedly connected to the threaded rod. When the threaded rod rotates, the circular plate fixed to the surface of the threaded rod can rotate synchronously.

[0007] Preferably, the circular plate is penetrated by the slider and is slidably connected to the slider. The surface of the slider is fixedly connected to one end of spring one, and the other end of spring one is fixedly mounted on the surface of the circular plate. When the slider is resisted, it can slide into the circular plate under the support of spring one.

[0008] Preferably, a support ring is fixedly mounted on the surface of the correction frame, and a limit block is fixedly mounted on the inner wall of the support ring. The spacing between the limit blocks can limit the rotation of the clamping rod and the disc.

[0009] Preferably, the inner wall of the support ring is rotatably connected to the surface of the disc, and the surface of the disc is fixedly connected to the surface of the threaded rod. When the disc is subjected to force, it can drive the threaded rod to perform circular motion in the correction frame.

[0010] Preferably, a support block is fixedly mounted on the surface of the disc, and a vertical rod is fixedly mounted on the inner wall of the disc. The arrangement of the vertical rod can provide a stable supporting force for the longitudinal movement of the clamping rod.

[0011] Preferably, the vertical rod passes through the card rod and is slidably connected to the card rod, the surface of the card rod is fixedly connected to one end of spring two, the other end of spring two is fixedly installed on the surface of the vertical rod, and a pressure block is fixedly installed on the surface of the card rod, the card rod passes through the disc and is slidably connected to the disc.

[0012] Compared with the prior art, the present invention provides a positioning pin correction device for wheel hub processing, which has the following beneficial effects:

[0013] 1. The positioning pin correction device for wheel hub processing is provided with a control component. A disc is rotated on the inner wall of the support ring. The disc is subjected to force to drive the threaded rod to rotate in the correction frame. When the threaded rod rotates, the movable block can be subjected to force to drive the correction block to move laterally. At the same time, when the threaded rod rotates, the circular plate fixed on the surface of the threaded rod can rotate synchronously in the fixed ring. During the rotation of the circular plate, the slider slidingly connected in the circular plate will abut against the surface of the protrusion provided on the inner wall of the fixed ring. When the protrusion abuts the cross-section of the slider, the slider will slide into the circular plate under the support of spring 1. The protrusion buffers the rotation speed of the circular plate and the threaded rod, so that the movable block and the correction block can be adjusted slowly to avoid large deviations due to excessively fast movement speed, which affects the correction of the positioning pin by the correction block.

[0014] 2. The positioning pin correction device for wheel hub processing is provided with an adjusting part. When the disc rotates in the support ring, the threaded rod fixed on the surface of the disc can rotate synchronously in the correction frame. Therefore, when the clamping rod in the disc is not subjected to the squeezing force, the clamping rod will always be in the distance between the two sets of limit blocks. The limit blocks can limit the rotation of the clamping rod and the disc. This method can enhance the stability of the moving block and the correction block after adjustment, and avoid displacement due to accidental touch during the correction process.

DETAILED DESCRIPTION

[0022] like Figures 1-6As shown, the utility model provides a technical solution: a positioning pin correction device for wheel hub processing, including a wheel hub processing table 1, a support seat 2 is fixedly installed on the surface of the wheel hub processing table 1, a positioning pin 3 is provided on the surface of the support seat 2, a fixing seat 4 is fixedly installed on the surface of the wheel hub processing table 1, the surface of the fixing seat 4 is rotatably connected to the rotating ring 5, a correction frame 6 is fixedly installed on the surface of the rotating ring 5, a control component 7 for adjusting the position of the positioning pin 3 is provided in the correction frame 6, and the control component 7 includes: a correction block 71, a moving block 72 is fixedly installed on the surface of the correction block 71, the moving block 72 is slidably connected to the inner wall of the correction frame 6, and the moving block 72 is penetrated by a threaded rod 73 The lock is locked and locked, and the locking cam 762 is locked, so the locking cam 763 is locked and the locking cam 764 is locked.

[0023] The control assembly 7 also includes an adjustment member 76, which includes a circular plate 761. The circular plate 761 is penetrated by the threaded rod 73 and fixedly connected to the threaded rod 73. When the threaded rod 73 rotates, the circular plate 761 fixed to the surface of the threaded rod 73 can rotate synchronously. The circular plate 761 is penetrated by the slider 763 and is slidably connected to the slider 763. The surface of the slider 763 is fixedly connected to one end of the spring 1 762, and the other end of the spring 1 762 is fixedly mounted on the surface of the circular plate 761. When the slider 763 is resisted, it can slide into the circular plate 761 under the support of the spring 1 762. A support ring 764 is fixedly mounted on the surface of the correction frame 6. The inner wall of the support ring 764 is fixedly mounted with a limit block 765. The spacing between the limit blocks 765 can limit the rotation of the clamping rod 769 and the circular plate 766. The inner wall of support ring 764 is rotatably connected to the surface of disk 766, which is fixedly connected to the surface of threaded rod 73. When force is applied to disk 766, it can drive threaded rod 73 to perform circular motion within correction frame 6. A support block 767 is fixedly mounted on the surface of disk 766, and a vertical rod 768 is fixedly mounted on the inner wall of disk 766. The arrangement of vertical rod 768 can provide stable support for the longitudinal movement of clamping rod 769. The vertical rod 768 passes through the card rod 769 and is slidably connected to the card rod 769. The surface of the card rod 769 is fixedly connected to one end of the spring 2 7610. The other end of the spring 2 7610 is fixedly installed on the surface of the vertical rod 768. A pressure block 7611 is fixedly installed on the surface of the card rod 769. The card rod 769 passes through the disc 766 and is slidably connected to the disc 766. When the pressure block 7611 is squeezed, the card rod 769 fixed on the surface of the pressure block 7611 can move longitudinally on the surface of the vertical rod 768.

[0024] In the present invention, when in use, when the position of the positioning pin 3 needs to be corrected, the pressure block 7611 is pressed downward on the surface of the disc 766, and the clamping rod 769 fixed on the surface of the pressure block 7611 can be subjected to force and move longitudinally on the surface of the vertical rod 768. When the clamping rod 769 moves, it can be moved out of the gap between the two sets of limit blocks 765. After moving out, the force of pressing the pressure block 7611 is maintained, and the disc 766 is driven to rotate on the inner wall of the support ring 764 through the support block 767. When the disc 766 rotates, the disc The threaded rod 73 fixed on the surface of 766 can rotate synchronously in the correction frame 6, and during the rotation of the threaded rod 73, the circular plate 761 fixed on the surface of the threaded rod 73 can rotate synchronously in the fixed ring 74. When the threaded rod 73 rotates, the moving block 72 can be forced to drive the correction block 71 to move laterally, and during the rotation of the circular plate 761, the slider 763 slidingly connected in the circular plate 761 will abut against the surface of the protrusion 75 provided on the inner wall of the fixed ring 74, and the protrusion 75 abuts against the slider 763. When cutting, the slider 763 will slide into the circular plate 761 under the support of the spring 1 762, and the protrusion 75 will buffer the rotation speed of the circular plate 761 and the threaded rod 73, so that the moving block 72 and the correction block 71 can be adjusted slowly to avoid large deviations due to excessive movement speed, which affects the correction of the positioning pin 3 by the correction block 71. After correction, the force of pressing the pressing block 7611 is released, and the clamping rod 769 can bounce up under the support of the spring 2 7610 and be stuck in the gap between the two sets of protrusions 75, thereby enhancing the stability of the moving block 72 and the correction block 71 after adjustment and avoiding displacement due to accidental touch during the correction process. After fixation, the rotating ring 5 is rotated on the surface of the fixing seat 4, and the correction frame 6 fixed on the surface of the rotating ring 5 performs circular motion synchronously. When the correction frame 6 rotates, it can be seen whether the cut surface at the bottom of the correction block 71 contacts the surface of the positioning pin 3. If it contacts and passes, it means that the adjustment is accurate. If it cannot pass or does not contact, the corresponding positioning pin 3 can be adjusted, which is very convenient.

[0025] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
