Surface wiping machine for disc-shaped parts

Abstract

The invention discloses a surface wiping machine for disc-shaped parts. The surface wiping machine comprises a part storage tank, a part supply machine, a part recovery machine, a feeding and discharging robot and a wiping device, wherein the part storage tank is provided with a limiting groove used for storing parts; a plurality of to-be-wiped parts can be stacked on the part supply machine, andthe uppermost part is located at the to-be-clamped altitude; the part recovery machine is used for stacking multiple wiped parts; the feeding and discharging robot is provided with clamping jaws whichcan make contact with the outer circumferential surfaces of the parts and are matched with one another to clamp the parts, and can move between the part supply machine, the part storage tank and thepart recovery machine; and the wiping device is used for wiping a part placed on the part storage tank. According to the scheme, the independent stations can be organically combined through the feeding and discharging robot to form an automatic system, so that the automation degree is high, and the machining efficiency is improved; and meanwhile, the clamping jaws of the feeding and discharging robot make contact with the circumferential surfaces of the disc-shaped parts, so that damage to the upper and lower surfaces of the parts is avoided; and meanwhile, the problem that the parts are contaminated and scratched again after being wiped can be solved, and the wiping effect and quality of the parts can be guaranteed.

Description

technical field [0001] The invention relates to the field of wiping machines, in particular to a surface wiping machine for disc-shaped parts. Background technique [0002] For disc-shaped or ring-shaped parts, when processing or testing or surface cleaning or grinding or polishing, it is necessary to make the upper and lower surfaces of the parts face up to facilitate the corresponding operations. The existing operation is mainly to manually place the parts in a After the position is wiped by a wiping machine, the efficiency of manual loading and unloading is low, and the labor intensity is high. It is impossible to automate the entire process of loading, wiping, and unloading, and the integration of the equipment is poor.

Problems solved by technology

[0002] For disc-shaped or ring-shaped parts, when processing or testing or surface cleaning or grinding or polishing, it is necessary to make the upper and lower surfaces of the parts face up to facilitate the corresponding operations. The existing operation is mainly to manually place the parts in a Wipe with a wiping machine after positioning, the efficiency of manual loading and unloading is low, the labor intensity is high, the automation of the whole process of loading, wiping, and unloading cannot be realized, and the integration of the equipment is poor

[0003] There are also some structures that use manipulators to load and unload parts. However, conventional two-jaw manipulators often move by clamping the upper and lower surfaces or the outer peripheral surface of the parts. Contacting and applying force can easily cause damage to the surface of the part, resulting in defective products and reducing the yield rate. Moreover, when the surface is cleaned or ground or polished, the jaws are also likely to cause re-contamination and damage to the surface of the part. Affect cleaning, grinding, polishing quality

[0004] For the clamping scheme using the circumferential surface, such as the two-jaw clamp with the patent number 201521127869.9, there must be sufficient clamping force to ensure the stability of the clamping when the two jaws are clamped, otherwise the parts may turn over during the movement process. In the case of tilting and falling, this is not conducive to stable and accurate feeding, and the clamping force is too large, and it is easy to deform parts, especially thin parts, which affects product quality

[0005] There is also a plan to use multiple jaws to clamp from the outer peripheral surface of a disc-shaped part, such as a three-jaw clamp with application number 201610280777.7, which realizes clamping by rotating the three jaws along a horizontal axis respectively. expansion and contraction, the problem is that each jaw needs a large length or a large rotation angle to ensure that the final contracted state can surround the parts, which is not conducive to the miniaturization of the equipment
