Description

A plastic push-out mechanism for machining splined shafts Technical Field

[0001] This utility model relates to the field of spline shaft processing technology, specifically a plastic removal mechanism for spline shaft processing. Background Technology

[0002] A splined shaft is a mechanical component typically used to transmit torque or motion between two rotating parts. It consists of a series of evenly distributed protrusions (teeth) along the shaft surface, which mate with corresponding grooves (spline sleeves) on the other part. Splined shafts can be external splines (teeth on the outside) or internal splines (teeth on the inside).

[0003] During the manufacturing process of splined shafts, some plastic parts remain on them. After the splined shaft is manufactured, the plastic parts on its surface need to be removed. However, if the plastic parts break during the existing process of pushing the plastic on the surface of the splined shaft, it can easily affect the normal use of the splined shaft. Therefore, we propose a plastic removal mechanism for splined shaft processing. Summary of the Invention

[0004] The purpose of this invention is to provide a plastic removal mechanism for processing splined shafts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic push-out mechanism for processing spline shafts, comprising a housing and an upper push head at the bottom and top of the spline shaft. The housing is hinged with an opening and closing door. Multiple sets of bases are fixedly installed at the bottom of the housing. A removal mold for positioning the bottom of the spline shaft is provided on the housing. A lower pressing mechanism for driving the upper push head to move up and down is provided at the top of the housing. The upper push head is fixedly installed on the lower pressing mechanism. A return mechanism for pushing the spline shaft out of the removal mold is provided on the housing and inside the removal mold.

[0006] Furthermore, the pressing mechanism includes a limiting rod, a limiting block, a mounting plate, and a driving cylinder. Multiple sets of limiting rods are fixedly installed inside the housing. Limiting blocks are slidably connected to the limiting rods. A mounting plate is fixedly installed outside the limiting blocks. A driving cylinder is fixedly installed on the top of the housing. The output end of the driving cylinder is fixedly connected to the mounting plate.

[0007] Furthermore, the removal mold includes a positioning seat, a release seat, and removal bosses. The positioning seat is fixedly installed on the housing, and the release seat is fixedly installed on the top of the inner wall of the positioning seat. The inner wall of the release seat is provided with multiple sets of removal bosses.

[0008] Furthermore, the recovery mechanism includes a recovery cylinder, a connecting rod, a limiting sleeve, and a lower positioning head. The recovery cylinder is fixedly installed inside the housing. The output end of the recovery cylinder is fixedly connected to the connecting rod. A limiting sleeve that fits against the inner wall of the positioning seat is fixedly installed on the top of the connecting rod. A lower positioning head is fixedly installed on the top of the limiting sleeve.

[0009] Furthermore, a mounting base is fixedly installed on the bottom of the mounting plate, and a detachable fixing plate is provided at the bottom of the mounting base, with the upward pushing head installed on the bottom of the fixing plate.

[0010] Furthermore, the positioning seat is fixedly installed on the housing by multiple sets of locking bolts.

[0011] Compared with the prior art, the present invention has the following advantages: The removal mold set in the present invention can initially position the bottom of the spline shaft. Then, the pressing mechanism operates, and the pressing mechanism drives the upper push head to descend. The upper push head is positioned with the top of the spline shaft. Then, the pressing mechanism continues to move, so that the spline shaft can move continuously along the inside of the removal mold. In this way, the plastic parts in the spline shaft can be quickly removed by the removal mold. After the plastic parts of the spline shaft are removed, the set return mechanism can push the spline shaft out from the inside of the removal mold. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please refer to Figures 1-5. This utility model provides a technical solution: a plastic push-out mechanism for processing spline shafts, including a housing 1 and an upper push head 5 at the bottom and top of the spline shaft. The housing 1 is hinged with an opening and closing door 2. Multiple sets of bases 3 are fixedly installed at the bottom of the housing 1. A removal mold 6 for positioning the bottom of the spline shaft is provided on the housing 1. A lower pressing mechanism 4 for driving the upper push head 5 to move up and down is provided at the top of the housing 1. The upper push head 5 is fixedly installed on the lower pressing mechanism 4. A return mechanism 7 for pushing the spline shaft out of the removal mold 6 is provided on the housing 1 and inside the removal mold 6.

[0020] The removal mold 6 is designed to initially position the bottom of the spline shaft. Then, the pressing mechanism 4 operates, driving the upper push head 5 to descend and positioning it against the top of the spline shaft. The pressing mechanism 4 continues to move, allowing the spline shaft to move continuously along the inside of the removal mold 6. This allows the removal mold 6 to quickly remove the plastic parts from the spline shaft. After the plastic parts are removed, the return mechanism 7 pushes the spline shaft out of the removal mold 6.

[0021] Please refer to Figures 1, 2 and 3. The pressing mechanism 4 includes a limiting rod 8, a limiting block 9, a mounting plate 10 and a driving cylinder 11. Multiple sets of limiting rods 8 are fixedly installed inside the housing 1. The limiting block 9 is slidably connected to the limiting rod 8. The mounting plate 10 is fixedly installed outside the limiting block 9. The driving cylinder 11 is fixedly installed on the top of the housing 1. The output end of the driving cylinder 11 is fixedly connected to the mounting plate 10.

[0022] When the upper push head 5 needs to be moved down, the drive cylinder 11 operates, and the drive cylinder 11 pushes the mounting plate 10, the upper push head 5 and the limit block 9 down along the limit rod 8, so that the upper push head 5 contacts and positions itself with the top of the spline shaft. As the drive cylinder 11 continues to move, the spline shaft can move along the inside of the removal mold 6, and the removal mold 6 can be used to remove the plastic parts on the spline shaft.

[0023] Please refer to Figures 1, 2, 3 and 4. The removal mold 6 includes a positioning seat 12, a release seat 13 and a removal boss 14. The positioning seat 12 is fixedly installed on the housing 1. The release seat 13 is fixedly installed on the top of the inner wall of the positioning seat 12. The inner wall of the release seat 13 is provided with multiple sets of removal bosses 14.

[0024] In this process, the splined shaft from which the plastic part needs to be removed is inserted into the inside of the release seat 13. Then, the plastic part on the splined shaft corresponds to the position of the removal boss 14. Subsequently, the pressing mechanism 4 continues to operate, which can remove the boss 14 and complete the rapid removal of the splined shaft plastic part.

[0025] Please refer to Figures 1-5. The recovery mechanism 7 includes a recovery cylinder 15, a connecting rod 16, a limiting sleeve 17, and a lower positioning head 18. The recovery cylinder 15 is fixedly installed inside the housing 1. The output end of the recovery cylinder 15 is fixedly connected to the connecting rod 16. The top of the connecting rod 16 is fixedly installed with the limiting sleeve 17, which fits against the inner wall of the positioning seat 12. The top of the limiting sleeve 17 is fixedly installed with the lower positioning head 18.

[0026] As the spline shaft descends along the inside of the positioning seat 12, the lower positioning head 18 contacts and positions the bottom of the spline shaft. Subsequently, the recovery cylinder 15 and the limiting sleeve 17 descend. After the plastic parts of the spline shaft are removed, the recovery cylinder 15 drives the connecting rod 16 and the limiting sleeve 17 to move upward along the positioning seat 12, thus pushing the spline shaft out of the positioning seat 12 after the plastic parts have been removed.

[0027] Please refer to Figures 1 and 2. The bottom of the mounting plate 10 is fixedly mounted with a mounting base 19. The bottom of the mounting base 19 is provided with a detachable fixing plate 20. The upper push head 5 is mounted on the bottom of the fixing plate 20.

[0028] The upper push head 5 is fixedly mounted on the mounting plate 10 via the mounting base 19 and the fixing plate 20. This configuration allows for easy replacement of the upper push head 5 and facilitates the processing of spline shafts of different specifications.

[0029] Please refer to Figures 1 and 4. The positioning seat 12 is fixedly installed on the housing 1 by multiple sets of locking bolts. The positioning seat 12 is fixedly installed by multiple sets of locking bolts, which makes it easy to replace the positioning seat 12 and facilitates the processing of splined shafts of different specifications.

[0030] In use, the removal mold 6 first initially positions the bottom of the spline shaft. Then, the pressing mechanism 4 operates, causing the upper push head 5 to descend and position itself against the top of the spline shaft. The pressing mechanism 4 continues to move, allowing the spline shaft to move continuously within the removal mold 6, thus quickly removing the plastic parts from the spline shaft. After the plastic parts are removed, the return mechanism 7 pushes the spline shaft out of the removal mold 6. When the upper push head 5 needs to move downwards, the drive cylinder 11 operates, pushing the mounting plate 10, the upper push head 5, and the limit block 9 downwards along the limit rod 8, causing the upper push head 5 to contact and position itself against the top of the spline shaft. With the continuous movement of the drive cylinder 11, the spline shaft moves along the inside of the removal mold 6, allowing it to be quickly removed. 6. To remove the plastic parts from the splined shaft, the splined shaft with the plastic parts removed is inserted into the release seat 13. The plastic parts on the splined shaft then correspond to the removal boss 14. The pressing mechanism 4 continues to operate, which allows the removal boss 14 to quickly remove the plastic parts from the splined shaft. As the splined shaft descends along the inside of the positioning seat 12, the lower positioning head 18 contacts and positions the bottom of the splined shaft. Then, the recovery cylinder 15 and the limit sleeve 17 descend. After the plastic parts of the splined shaft are removed, the recovery cylinder 15 drives the connecting rod 16 and the limit sleeve 17 to move upward along the positioning seat 12. This allows the splined shaft with the plastic parts removed to be pushed out of the positioning seat 12. The upper push head 5 is fixedly installed on the mounting plate 10 through the mounting seat 19 and the fixing plate 20. This setting allows for easy replacement of the upper push head 5 and facilitates the processing of splined shafts of different specifications.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
