Description

Technical Field

[0001] This invention relates to the field of workpiece processing technology, and in particular to a hole-type grinding processing equipment. Background Technology

[0002] Bamboo-like spots (one dark spot + one bright spot; the surface of the dark spot is uneven, with a difference of 7-8 μm between the high and low points; the surface of the bright spot is relatively smooth, without obvious unevenness) often appear on the surface of the finished wire produced by the high-speed wire rod rolling production line of the steel mill, which seriously affects the appearance quality of the product and the mechanical descaling of downstream users.

[0003] The bamboo-like spots on the surface of finished wire products are closely related to the periodic vibrations generated by the rolling groove (roller ring hole type) during grinding. In order to eliminate the generation of bamboo-like spots, it is necessary not only to improve the processing accuracy as much as possible when processing the roller ring hole type, but also to establish strict inspection standards. The processed finished products are inspected multiple times by dial indicators and cylindricity testers, and only those that pass the inspection are used.

[0004] In the existing technology, the roller ring needs to be repeatedly disassembled and re-clamped between the grinding machine, cylindricity tester and inspection table during the processing and inspection process. This is inefficient and time-consuming. Each clamping will inevitably produce a certain positioning error, which seriously affects the processing accuracy and inspection accuracy.

[0005] Therefore, there is a need for a hole grinding machine that can achieve one-time clamping and multi-sequence flow of roller rings, eliminate the need for repeated clamping, and minimize positioning errors. Summary of the Invention

[0010] Furthermore, the length of the rotating column is greater than the total length of the first rotating frame, the horizontal stop bar, and the second rotating frame.

[0011] Furthermore, a force-applying rod is inserted into the force-applying hole to apply a force that causes the foundation positioning tube and the rotating column to rotate; the force-applying rod is a straight metal rod.

[0023] like Figures 1 to 3 As shown, the hole grinding equipment of this application is used to support the roller ring 001 during the positioning and inspection process. After the inner hole of the roller ring 001 is precision machined, it is fixed on the movable clamping accessory of the hole grinding equipment of this application so as to ensure the smooth and efficient operation of subsequent processing and inspection processes. The hole-shaped grinding equipment of this application includes multiple positioning accessories 100, and also includes movable clamping accessories; The positioning accessory 100 is fixed on the rotating shaft of a component used to drive the roller ring 001 that needs to be processed (processing or inspection) to rotate on a grinding machine, cylindricity tester, inspection stand, etc., and includes a stud 110; the stud 110 is a hard straight shaft with threads on the outer wall, and after being installed and fixed, it rotates coaxially with the rotating shaft of the component used to drive the roller ring 001 that needs to be processed to rotate.

[0024] The movable clamping accessory is used to be detachably fixed to the roller ring 001 that needs to be processed by an internal expansion method; The movable clamping accessories include a basic positioning tube 200, an abutment fixing unit 300, a positioning carrier tube 400, and a rotating column 500; The basic positioning tube 200 is a threaded tube with built-in threads, and its internal threads match the external threads of the stud 110. The positioning tube 400 is a threaded tube with built-in threads and is coaxial with the basic positioning tube 200; The contact fixing unit 300 connects and positions the basic positioning tube 200 and the positioning carrier tube 400 together; The contact fixing unit 300 includes three contact components, each of which is positioned at one end of the base positioning tube 200 and at the other end of the positioning carrier tube 400; the three contact components are arranged in a ring around the axis of the base positioning tube 200 and are spaced equally apart from each other. The abutting component includes a first rotating frame 310, a horizontal abutting rod 320, and a second rotating frame 330; The first rotating frame 310 is a rod-shaped frame, with one end rotatably connected to the side wall of the base positioning tube 200 near the end, and the axis of the rotating shaft is perpendicular to the axis of the base positioning tube 200. The horizontal abutment 320 is a horizontally arranged rigid rod, one end of which is rotatably connected to the other end of the first rotating frame 310, and the axis of the rotating shaft is perpendicular to the axis of the base positioning tube 200. The second rotating frame 330 is a rod-shaped frame, which has the same structure as the first rotating frame 310 and is symmetrically arranged. One end is rotatably connected to the other end of the horizontal abutment 320, and the other end is rotatably connected to the side wall of the positioning carrier tube 400 near the end. The axial direction of the rotating shaft is perpendicular to the axial direction of the base positioning tube 200. The rotating column 500 is a threaded column, and its length is greater than the total length of the first rotating frame 310, the horizontal abutment 320 and the second rotating frame 330. The outer wall is provided with threads, and the threads match the threads of the positioning carrier tube 400. The rotating column 500 is inserted through and tightened onto the positioning carrier tube 400, and one end is rotatably connected to the base positioning tube 200. The axis of the rotating shaft coincides with the axis of the base positioning tube 200. At least one force-applying hole 510 is positioned on the side wall of the base positioning tube 200 and the side wall of the rotating column 500; the axial direction of the force-applying hole 510 is perpendicular to the axial direction of the base positioning tube 200, so as to facilitate the application of a force to the base positioning tube 200 and the rotating column 500 to make them rotate.

[0026] After the inner hole of the roller ring 001 is precision machined, the movable clamping accessory is inserted into the inner hole of the roller ring 001. Then, the rotating column 500 is rotated so that the transverse abutment 320 moves away from the rotating column 500 until it contacts and presses against the inner wall of the roller ring 001, thereby installing and fixing the movable clamping accessory on the roller ring 001. After that, the base positioning tube 200 is tightened and fixed on the positioning accessory 100 on the grinding machine. After the fine grinding is completed, the movable clamping accessory and the roller ring 001 are removed together and tightened and fixed on other positioning accessories 100 for inspection. Using the movable clamping accessory to support the roller ring 001 can reduce repeated positioning errors, save time for repeated alignment and calibration, and significantly improve production and inspection efficiency. The uniform tension force makes the roller ring 001, the contact fixing unit 300 and the base positioning tube 200 form a rigid whole. During fine grinding, it can effectively suppress the micro-vibration and deformation caused by cutting force, thereby reducing the generation of vibration marks.
