Description

Technical Field

[0001] The invention relates to the technical field of polishing, and in particular to an axial continuous polishing device and a polishing method for a valve housing of unequal outer diameters. Background Art

[0002] The role of polishing is to reduce the surface roughness of the workpiece to obtain a bright and flat surface. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but is aimed at obtaining a smooth surface or mirror gloss. The existing polishing objects are mostly objects of unequal outer diameters. Traditional polishing of objects of unequal outer diameters requires manual polishing, which has slow polishing efficiency and poor polishing effect.

[0003] The existing patent (Announcement No.: CN201510569087.9) proposes a stainless steel pipe outer diameter polishing device. The working principle of the stainless steel pipe outer diameter polishing device is as follows: the sleeve is driven to rotate by the motor through the bevel gear, and the stainless steel pipe to be polished is inserted into the sleeve and is coaxial with the sleeve. The rotation of the sleeve relative to the turntable can change the radial extension length of the turntable and the sleeve upper rod, that is, the length of the polishing grinding head extending toward the center of the sleeve, until the polishing grinding head reaches the outer wall of the steel pipe, so that it can adapt to steel pipes with different outer diameters.

[0004] The above-mentioned polishing device adopts a technical solution for solving the problem of tube polishing that the sleeve rotates relative to the turntable to change the radial extension length of the turntable and the rod on the sleeve, that is, the length of the polishing grinding head extending toward the center of the sleeve, until the polishing grinding head hits the outer wall of the steel pipe, so that it can adapt to steel pipes with different outer diameters. However, there is a problem with this case. The device cannot polish steel pipes with unequal outer diameters. Specifically, since the outer diameters of pipes with unequal outer diameters gradually increase or decrease, it is necessary to control the radial extension length of the rod of the sleeve to increase or decrease during polishing. Otherwise, the grinding head will over-polish or under-polish the steel pipe, which is obviously very troublesome and difficult. Therefore, we propose an axial continuous polishing device and a polishing method for valve housings of unequal outer diameters to solve the above-mentioned problem. Summary of the invention

Specifically as follows: The bottom end of the unequal outer diameter valve housing body 18 is sleeved on the lower rotating column 152 of the clamping mechanism 1, and the first lifting cantilever plate 14 is controlled by the first driving component to lift and lower, and the upper rotating column 142 is sleeved on the top of the unequal outer diameter valve housing body 18, so that the upper rotating column 142 and the lower rotating column 152 clamp the unequal outer diameter valve housing body 18; The longitudinal lifting mechanism 3 is started, so that the cylindrical outer wall of the first polishing position of the unequal outer diameter valve housing body 18 and the polishing belt 74 are at the same horizontal position and in tangential contact; and the unequal outer diameter valve housing body 18 is rotated in the first direction, so that the polishing belt 74 is rotated in the second direction, and the two are in contact and perform polishing operation at the first polishing position; The longitudinal lifting mechanism 3 is started to gradually lower the unequal outer diameter valve housing body 18, and the angle of the clamping mechanism 1 is adjusted by starting the angle adjustment mechanism 2, so that the conical outer wall at the second polishing position is forced to be tangentially contacted with the polishing belt 74, and the unequal outer diameter valve housing body 18 and the polishing belt 74 rotate to polish the conical outer wall at the second polishing position of the unequal outer diameter valve housing body 18; During the gradual descent of the unequal outer diameter valve housing body 18, the angle adjustment mechanism 2 and the lateral movement mechanism 5 are continuously started to cooperate with each other so that the outer wall of the large diameter cylinder at the third polishing position continues to be tangent to and fits with the polishing abrasive belt 74 for polishing; When polishing to the fourth polishing position and the fifth polishing position, the regulating directions of the longitudinal lifting mechanism 3, the lateral moving mechanism 5 and the angle adjusting mechanism 2 are opposite to those of polishing at the first polishing position and the second polishing position.
