Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a grinding machine. Background Technology

[0002] A grinding machine is a machine tool that uses a high-speed rotating grinding wheel or other abrasive to perform precision machining on the surface of a workpiece. Its core functions include surface finishing, material removal, and shape correction. Currently, grinding machines primarily use grinding media to polish workpieces. During the grinding process, a nozzle delivers coolant to the workpiece, thus cooling it. After the workpiece cools, the coolant enters the grinding machine body within its internal chamber, where a filter screen filters the coolant, allowing for coolant storage and subsequent circulation.

[0003] While the above method can grind the workpiece, iron filings are generated during the grinding process. After the coolant cools the workpiece, some of the iron filings will enter the chamber with the coolant and be filtered by the filter screen to reduce the iron filings residue in the coolant. However, if the filter screen filters iron filings for a long time, it is easy to cause the filter screen to become clogged. Once the filter screen becomes clogged, it needs to be cleaned by personnel, which will greatly increase the labor force and reduce the filtration effect of the filter screen on the coolant. Utility Model Content

[0004] The purpose of this invention is to provide a grinding machine that can backwash the filter screen inside the grinding machine body, thereby reducing the likelihood of the filter screen becoming clogged.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A grinding machine, comprising: a grinding machine body with a built-in chamber, a clamping member disposed on the grinding machine body, a grinding workpiece disposed on the grinding machine body, a filter screen fixedly connected to a wall chamber, a liquid inlet hole disposed on the grinding machine body and communicating with the chamber, and a nozzle disposed on the grinding workpiece, wherein the grinding workpiece and the clamping member are disposed opposite to each other, and the nozzle is used to transmit coolant into the workpiece.

[0025] The grinding machine of this utility model also includes: a movable seat 8, a sliding seat 9, a nozzle 10, and an infusion component 11;

[0026] The movable seat 8 is slidably connected to the chamber 1 by the cylinder 3. The cylinder 3 is fixedly connected to the grinding machine body 2, and its output shaft is fixedly connected to the movable seat 8, thus enabling the movable seat 8 to slide. The sliding seat 9 is slidably connected to the movable seat 8 by the cylinder 4. The cylinder 4 is fixedly connected to the movable seat 8, and its output shaft is fixedly connected to the sliding seat 9, thus enabling the sliding seat 9 to slide. The nozzle 2 10 is fixedly connected to the sliding seat 9. The liquid delivery component 11 is located in the chamber 1. The liquid delivery component 11 is connected to the nozzle 2 10 and is used to transfer the coolant in the chamber 1 into the nozzle to backwash the filter screen 5. The liquid delivery component 11 is mainly a liquid pump 2. One end of the liquid pump 2 is connected to the nozzle 2 10 through a pipe, which enables the transfer of coolant.

[0027] After backwashing the filter screen 5, a lifting seat 12 is vertically slidably connected inside the chamber 1. A dust-collecting block 14 with a suction groove 13 at the bottom is fixedly connected to the bottom of the lifting seat 12.
