Description

Technical Field

[0001] The present invention relates to the technical field of processing equipment, and in particular to a processing device for shafts. Background Art

[0002] Scraping and grinding is a key finishing method in the field of mechanical manufacturing. Its core technology has long been limited by the singleness of tool materials. Traditional scraping and grinding tools are mostly made of a single material. This "one tool, one material" paradigm exposes serious adaptation difficulties when facing the increasing number of multi-material composite structures in modern manufacturing. Traditional processes require frequent tool changes for scraping and grinding when repairing some shaft end faces, which reduces the overall processing efficiency. For this reason, we propose a processing device for shafts. Summary of the invention

[0003] 1. Technical issues to be resolved

[0007] A processing device for shafts includes an outer frame and a supporting shaft connected to the outer frame, and also includes a scraping unit connected to the outer frame. The scraping unit includes a platform frame and an I-shaped wheel. The I-shaped wheel is installed inside the platform frame to rotatably support the I-shaped wheel, and the I-shaped wheel and the supporting shaft are synchronously driven by a synchronous belt. A plurality of trapezoidal guide blocks are arranged on the bottom side of the upper wheel of the I-shaped wheel, and I-shaped wheel teeth corresponding to the trapezoidal guide blocks are arranged on the top side of the lower wheel of the I-shaped wheel. A steering block is also connected to the platform frame, and a rotatable rotating shaft is passed through the steering block. A scraper is connected to one end of the rotating shaft, and the other end extends between the trapezoidal guide block and the I-shaped wheel teeth to control the flipping and tilting of the rotating shaft.

[0008] Preferably, the scraping unit further comprises a connecting plate connected to the platform frame, the connecting plate is connected to a steering block located at one side of the I-shaped wheel, and the steering block is rotatably arranged on the connecting plate through an axle.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See attached Figure 1-8 A shaft processing device includes an outer frame 1, which covers the end face of the shaft to be processed and is fixedly installed. The axis of the outer frame 1 is consistent with the axis of the processed shaft. A supporting shaft 12 is also arranged at the axis of the outer frame 1. One end of the supporting shaft 12 is connected to the output end of the motor, and the cone tip of the other end is supported by the end of the shaft. When the shaft is rotated, the motor controls the rotation of the supporting shaft 12.

[0030] The scraping unit connected to the outer frame 1 includes a platform frame 2 and an I-shaped wheel 21. The I-shaped wheel 21 is installed inside the platform frame 2 to support the I-shaped wheel 21 in rotation. The two end shafts of the I-shaped wheel 21 extend to the ends of the platform frame 2 so that the I-shaped wheel 21 can rotate along the axis inside the platform frame 2. A groove is arranged on the upper wheel circumference of the I-shaped wheel 21. The groove is sleeved with the abutting shaft 12 through a synchronous belt. When the abutting shaft 12 rotates, the I-shaped wheel 21 can be driven to rotate through the synchronous belt.

[0031] A plurality of trapezoidal guide blocks 22 are arranged on the bottom side of the upper wheel of the spool 21, and there are at least two trapezoidal guide blocks 22. A plurality of spool teeth 23 are arranged on the top side of the lower wheel of the spool 21, and the positions of the spool teeth 23 and the trapezoidal guide blocks 22 correspond.

[0032] The scraping unit also includes a connecting plate 24 connected to the platform frame 2, and a steering block 25 located on one side of the I-shaped wheel 21 is connected to the connecting plate 24. The steering block 25 is rotatably arranged on the connecting plate 24 through an axle body. A rotating shaft 26 is rotatably arranged on the steering block 25 through a bearing, and one end of the rotating shaft 26 is connected to a scraping knife 27, and the other end extends between the trapezoidal guide block 22 and the I-shaped wheel teeth 23. A shaft gear 28 capable of meshing with the I-shaped wheel teeth 23 is sleeved on the extended end of the rotating shaft 26, and a ball head 29 capable of abutting against the trapezoidal guide block 22 is also connected to the extended end of the rotating shaft 26; since a rotating shaft sleeve 261 is also sleeved on the extended end of the rotating shaft 26, a spring 262 is also connected between the platform frame 2 and the rotating shaft sleeve 261. In the initial state, the rotating shaft 26 is inclined, and the scraping knife 27 abuts against the end face of the shaft. On the upper part, the rotation of the supporting shaft 12 drives the I-shaped wheel 21 to rotate. When the I-shaped wheel 21 rotates, the scraper 27 contacts the end face of the shaft to perform a scraping action. When it continues to rotate, the trapezoidal guide block 22 will be supported on the ball head 29 so that the rotating shaft 26 is tilted with the steering block 25 as the axis. At this time, the shaft gear 28 will correspond to and mesh with the I-shaped wheel teeth 23. The edges on both sides of the trapezoidal guide block 22 are in a smooth curved shape, which drives the rotating shaft 26 to perform a rotational motion, so that the scraper 27 can be turned over, and the spring 262 resets it to continue scraping. One side of the scraper 27 is a soft material such as aluminum alloy and copper alloy, and the other side is a hard material such as quenched steel and ceramic coating. The soft blade surface is first used to remove impurities such as oxide layer and burrs in the rough scraping stage to avoid scratches on the hard blade surface due to the adhesion of impurities during fine processing, and then the hard blade surface is used for scraping.

[0033] The diameter of the upper wheel of the I-shaped wheel 21 is smaller than that of the lower wheel of the I-shaped wheel 21 , so as to facilitate the cooperation with the shaft gear 28 and the ball head 29 .

[0034] In order to completely scrape the end face of the shaft during scraping, a fixing frame 11 is fixedly connected to the side wall of the outer frame 1, and the scraping unit is rotatably arranged inside the fixing frame 11. The swing unit 3 drives the scraping unit to make a reciprocating motion to achieve complete scraping of the end face of the shaft. The swing unit 3 includes a driving wheel 31 sleeved on the rotating shaft of the I-shaped wheel 21, a reset gear 33 and a reduction gear 35 are connected to the platform frame 2, and an incomplete gear 32 is connected to the side of the driving wheel 31. When the incomplete gear 32 rotates, it meshes with the reset gear 33, and the reset gear 33 meshes with the reduction gear 35. A torsion spring 34 is also sleeved on the reset gear 33, and the torsion spring 34 One end is fixed on the reset gear 33 and the other end is fixed on the platform frame 2. When the I-shaped wheel 21 rotates, it drives the scraping unit to flip and also drives the driving wheel 31 to rotate. The incomplete gear 32 on the driving wheel 31 drives the reset gear 33 to rotate, so that the scraping unit deflects to one side. When the incomplete gear 32 and the reset gear 33 are not meshed, the reset gear 33 is reset under the action of the torsion spring 34, so that the scraping unit deflects to the other side, so that the end face of the shaft can be completely scraped and ground, and the reset gear 33 is always meshed with the reduction gear 35. Whether the reset gear 33 rotates clockwise or counterclockwise, it rotates slowly.
