Description

Technical Field

[0001] This utility model belongs to the field of grinding technology, and in particular relates to a tool grinder with a quick-change grinding wheel. Background Technology

[0002] During the production and processing of parts, workers need to use different models or types of tools to process the parts according to the production and processing requirements to obtain the required parts. Grinding tools is one of the production steps. Currently, workers use tool grinders to grind tools. Compared with traditional manual grinding, tool grinder grinding has the advantages of reducing the workload of workers and improving the grinding efficiency. The main grinding steps are: using a clamp to fix the position of the tool, turning on the motor, and driving the grinding wheel to rotate to grind the tool.

[0003] A search revealed a universal tool grinder disclosed in patent publication number CN220445924U, belonging to the field of universal tool grinders. The grinder includes a main body with a dust collection mechanism on its left side. This mechanism, in conjunction with the grinder body, allows for efficient dust collection when grinding workpieces and generating dust. A suction fan draws the dust into a dust hood via a suction pipe, where a filter within the hood adsorbs and filters the dust. Tiny dust particles are discharged into a water tank via a duct, preventing dust from dispersing and floating in the air, thus avoiding health risks. It also prevents dust accumulation after prolonged use, ensuring effective dust collection during workpiece grinding.

[0004] However, tool grinders still have the following shortcomings in practical use:

[0005] 1. A rotating shaft is connected to the output end of the motor. A limit ring is fitted on the circumferential side wall of the rotating shaft. Limit rods are fixed in a ring array on the side wall of the limit ring. The grinding wheel body is fitted on the circumferential side wall of the rotating shaft and abuts against the limit ring. The limit rods pass through the grinding wheel body. The position of the grinding wheel body is fixed by rotating the threaded connecting nuts on multiple limit rods in sequence. When disassembling and replacing the grinding wheel body, it is still necessary to rotate multiple nuts in sequence to release the fixation of the position of the grinding wheel body and disassemble the grinding wheel body. The disassembly and assembly steps are cumbersome, which is not conducive to the quick disassembly and replacement of the grinding wheel body and increases the workload of the staff.

[0006] 2. A longitudinal plate is mounted on the base plate. A guide groove is formed on the longitudinal plate, and a screw is connected inside the guide groove. A sleeve threaded on the peripheral wall of the screw is slidably connected inside the guide groove. A transverse plate is formed on the upper surface of the longitudinal plate, and a sleeve is connected to the lower surface of the transverse plate. A groove is formed on the upper surface of the transverse plate, and a sliding groove is formed on the inner side wall of the groove. A movable plate is connected to the transverse plate, and a clamp is connected to a base fixed on the upper surface of the movable plate. The clamp is used to hold the tool. Rotating the screw moves the transverse plate along the axial direction of the longitudinal plate, pushing the movable plate, and the clamp moves along the axial direction of the transverse plate, adjusting the tool to contact the grinding wheel body. When the motor is powered on, the grinding wheel body rotates to grind the tool. However, it is not convenient to adjust the orientation of the clamp on the horizontal plane, which reduces the adjustment range of the tool position, reduces applicability, and reduces practicality.

[0007] To address these issues, we provide a tool grinder with a quick-change grinding wheel. Utility Model Content
