Problems solved by technology

In order to ensure the surface quality after processing, the existing processing method is to use a fine-grained shaped grinding wheel for grinding; however, due to the small size of the grinding wheel and the small pores of the grinding wheel, the processing efficiency is very low in order to ensure that the processed surface does not burn

Embodiment 1

[0061] like figure 1 and figure 2 As shown, a polishing device for the inner spiral raceway of a single screw nut includes: a cylindrical center rod 2, the outer diameter of the center rod 2 is the same as the inner diameter of the screw nut 1, and the axis of the center rod 2 is consistent with the inner diameter of the screw nut 1. The axial length is greater than the axial length of the screw nut 1; the center rod 2 is arranged in the inner hole of the screw nut 1, so that part of the outer surface of the center rod 2 and the inner helical raceway A grinding pipe with only two ends open is formed; the base 3, corresponding to the position of the end of the grinding pipe, is provided with a second abrasive inlet and outlet for the abrasive to enter and exit; the top cover 4, corresponding to the position of the end of the grinding pipe, set There is a first abrasive inlet and outlet for abrasives to enter and exit; the connecting mechanism connects and fixes the center rod...

Embodiment 2

[0074] like Figure 3-8 As shown, a polishing device for the inner spiral raceway of a plurality of screw nuts includes: a central rod 20 is arranged in the inner hole of the screw nut 10, the central rod 20 and the screw nut 10 are one-to-one Correspondingly, a part of the outer surface of the central rod 20 and the inner spiral raceway form a grinding pipe with only two ends open; the top cover 40 is sleeved on the tops of the plurality of central rods 20, The cover 40 is provided with a plurality of first abrasive inlets and openings that communicate with each of the grinding pipes; the base 30 is located below the central rod 20, and the base 40 is provided with a plurality of first abrasive pipes that communicate with each of the grinding pipes Import and export of the second abrasive;

[0075] The top cover 40, the center rod 20, the screw nut 10 and the top cover are used for cooperative connection to form an integral structure;

[0076] The vibrating device 8 is conn...

Abstract

The invention is a polishing device for the inner spiral raceway of a single screw nut, comprising: a central rod; the screw nut to be polished is sheathed on the central rod, and part of the outer surface of the central rod is rolled with the inner spiral of the screw nut. A grinding pipeline is formed between the channels; the top cover is sleeved on the top of the center rod. Below, the base is provided with a second abrasive inlet and outlet connected to the grinding pipeline; the connecting mechanism connects and fixes the center rod, the screw nut, the base and the top cover to form an integral structure; the vibration device is connected with the base to adjust the overall The structure vibrates at high frequency, so that when the abrasive flow flows through the grinding pipe, the abrasive flow will fully rub against the inner spiral raceway of the screw nut.

Description

technical field [0001] The invention relates to the technical field of precision polishing equipment, in particular to a polishing device for inner helical raceways of a plurality of screw nuts. Background technique [0002] Polishing is the only way to achieve ultra-precise size, ultra-accurate shape and extremely low surface roughness on the surface of various solid materials, and it is also the best method to eliminate processing defects and damages of materials below the surface. Polishing has a wide range of applications and is capable of ultra-precision machining of various complex surfaces. Especially for the processing of various difficult-to-machine materials and complex surface parts used in the fields of optics and electronic information, the polishing process plays an irreplaceable role. [0003] The traditional polishing processing technology mostly adopts the low-speed processing method of granular abrasives, which has the disadvantages of low precision retent...
