Description

Technical Field

[0001] This utility model relates to the field of plug gauge processing technology, and in particular to a high-precision plug gauge grinding processing device. Background Technology

[0002] A plug gauge is a precision measuring tool mainly used to measure the dimensions of holes, hole spacing, and internal threads, and is particularly suitable for mechanical and electronic machining fields. Its basic structure is cylindrical, with a go end and a no-go end at each end, used to check the minimum and maximum limit dimensions of the hole diameter, respectively. When the go end passes through the hole diameter, it indicates that the hole diameter meets the minimum limit dimension; when the no-go end cannot pass through the hole diameter, it indicates that the hole diameter meets the maximum limit dimension, thus determining whether the hole diameter is qualified.

[0003] A search revealed Chinese patent application number 202121436991.X, which discloses a grinding machine for processing plug gauges, relating to the field of plug gauge processing equipment. The machine includes a frame, with a main control box at the upper end. Drive boxes and limiting plates are respectively located at both ends of the frame along its length.

The drive box contains a drive device for rotating the disc along its own axial direction. The frame has a clamping mechanism for moving the limiting plate along the length of the frame. This application has the effect of improving processing accuracy.

[0004] Although the aforementioned patent allows for the spraying of coolant onto the workpiece processing location via a spray pipe to continuously cool the workpiece, preventing deformation during processing and thus improving processing accuracy, the sprayed coolant can cool the workpiece and flush away most of the debris generated during grinding. However, residual debris can also affect grinding accuracy. Furthermore, debris adhering to other parts can affect the quality and accuracy of grinding, leading to a decrease in the precision of the processed workpiece.

[0005] Therefore, a high-precision plug gauge grinding machine is urgently needed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art that the sprayed grinding fluid can only wash away most of the debris at the machining location, and the residual debris and debris in the area to be machined can easily affect the machining accuracy of the workpiece. Therefore, a high-precision plug gauge grinding device is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] As a preferred technical solution of this application, a sliding door is slidably installed on the front of the cover, and foot pads are installed at the four corners of the bottom of the support platform.

[0012] As a preferred technical solution of this application, a material collection box is slidably installed on the top of the support platform between the drive box and the mounting base.

[0015] Compared with the prior art, this utility model provides a high-precision plug gauge grinding device, which has the following advantages:

[0016] 1. This high-precision plug gauge grinding device, through a chip removal brush parallel to the workpiece, after being adjusted according to the workpiece size, can brush off residual chips and other impurities on the workpiece surface into the collection box, effectively reducing the impact of workpiece surface chips on the grinding process, improving the workpiece's processing quality and accuracy, and solving the problem in the existing technology that the sprayed grinding fluid can only wash away most of the chips at the processing position, while residual chips and chips in the area to be processed can easily affect the processing accuracy of the workpiece.

[0017] 2. This high-precision plug gauge grinding device uses multiple compensating springs to connect the brush body and the inner surface of the chip removal brush. During use, it can automatically approach the workpiece during cleaning, making chip removal more convenient and improving the cleaning effect. This solves the problem in the prior art where the brush body wears down after a period of use, resulting in less contact area with the workpiece and a decrease in chip removal effect.
