Description

Technical Field

[0001] The invention relates to the technical field of post-processing of metallurgical parts, and in particular to a post-processing device and method for metallurgical parts. Background Art

[0002] Metallurgical parts usually refer to various metal parts or products manufactured through metallurgical processes. Metallurgical parts are widely used in many fields such as the automotive industry, aerospace, and construction industry. Metallurgical parts need to be post-processed after forming. The post-processing of metallurgical parts refers to a series of processing steps performed after the basic forming process is completed in order to improve material properties, surface quality, or meet specific application requirements. Polishing and grinding is also one of the important steps in the post-processing of metallurgical parts. Fig.14 and Fig.15 The medium and large spline rotors shown have a diameter between 200-500mm and are used in automobile manufacturing and heavy industrial equipment. They are mainly used in conjunction with clutch pins. In order to ensure that the clutch pin is smoothly inserted into the keyway and improve the matching accuracy between the two, the spline rotor needs to be polished. However, there are certain problems in the existing polishing equipment during the polishing of the spline rotor:

[0003] 1. The places where the spline rotor needs to be polished include the upper surface, the lower surface, the outer circumferential surface and the keyway mating surface. However, when the existing polishing equipment is performing polishing, it is necessary to use a polishing tool to polish several surfaces separately, and the polishing efficiency is low. In addition, the polishing of the keyway mating surface is usually performed by reciprocating polishing. The friction force of the up and down reciprocating polishing is large and directly acts on the spline rotor, which can easily cause the spline rotor to shake up and down, reducing stability. The upper and lower surfaces and the outer wall are usually polished by rotation, so different polishing heads and polishing drive mechanisms need to be replaced during the polishing process, which is time-consuming and has low polishing efficiency and is not suitable for mass production.

[0004] 2. The spline rotor needs to be clamped and positioned before grinding. The existing technology usually adopts the method of clamping and fixing with a triangular chuck. However, after clamping with the triangular chuck, the spline rotor is not axially crimped and fixed, and the position between the grinding head and the triangular chuck is not limited. The grinding stability is poor, which affects the grinding quality.

[0005] 3. When it is necessary to produce and process spline rotors in large quantities, multiple spline rotors are usually processed in one piece, which requires multiple triangular chucks for clamping, and the position between the triangular chuck and the grinding head needs to be precisely positioned. In the existing technology, the positioning of the triangular chuck and the locking and loosening of the spline rotor need to be controlled separately, which is cumbersome to operate.

[0018] A post-processing method for metallurgical parts is completed by using the above-mentioned post-processing equipment for metallurgical parts, and comprises the following steps:

[0019] S1: Loading and conveying; first, multiple spline rotors to be processed are installed on the moving seat, and the spline rotors are initially positioned using a step sleeve, and then the moving seat is conveyed along the annular linear guide rail.

[0020] S2: Positioning and locking: When the moving seat is transported to the rear side of the annular linear guide rail, the positioning and locking mechanism sequentially limits and blocks the multiple moving seats, and synchronously drives the hollow triangular chuck to lock and fix the spline rotor.

[0021] S3: Up and down staggered grinding: After the spline rotor is locked and fixed, the reciprocating switching mechanism drives the up and down staggered grinding mechanism to move downward, and the up and down staggered grinding mechanism is used to perform up and down alternating reciprocating grinding on the keyway of the spline rotor.

After grinding, the rotors are transported to the initial position, realizing batch cyclic conveying automatic grinding, with high grinding efficiency, and suitable for mass production.

[0026] 2. The present invention drives the upper and lower actuators to rise in sequence along the conveying direction of the moving seat through the driving assembly and the extrusion assembly, so that the moving seat is blocked and limited by the upper and lower actuators, thereby realizing the precise positioning of the moving seat, and the upper and lower actuators simultaneously drive the No. 1 spur gear and the square shaft to rotate while moving upward, thereby realizing the synchronous tightening of the hollow triangular chuck, which is beneficial to locking and fixing the spline rotor, and realizing the integrated precise positioning and locking and fixing of multiple spline rotors.

[0027] 3.

[0048] During the operation of the positioning and locking mechanism 7, first, multiple moving seats 2 are on the right side of the annular linear guide rail 6. At this time, the bottom of the spline rotor is inserted from top to bottom into the step sleeve 8, and the spline rotor is initially limited and fixed by using the step sleeve 8 and the boss at its bottom. Then, the moving seat 2 is transported from right to left along the annular linear guide rail 6.

As the No. 1 positioning plug pin 14 is inserted into the center hole of the step sleeve 8, the side grinding plate 343 moves toward the direction of the arc surface grinding head 345 through the guidance of the guide bevel groove at the bottom of the side grinding plate 343 and the arc surface grinding head 345, compressing the No. 4 spring 344, and the arc surface grinding head 345 moves away from the No. 1 positioning plug pin 14, compressing the No. 3 spring 342, until ...

[0064] S4: Rotational grinding: The movable seat 2 is transported to the front side of the annular linear guide rail 6, and the positioning and locking mechanism 7 on the front side locks and limits the multiple movable seats 2. Then the reciprocating switching mechanism 4 drives the rotational grinding mechanism 5 to descend, and the rotational grinding mechanism 5 is used to perform integrated rotational grinding on the upper surface, lower surface and outer wall of the spline rotor.
