Description

Technical Field

[0001] The present invention relates to the field of grinding equipment, in particular to a motor spindle grinder. Background Art

[0002] In many industries such as mechanical processing and furniture manufacturing, grinding operations are an indispensable and important link, and motor spindle grinders are widely used as commonly used grinding tools. However, existing motor spindle grinders have some problems. On the one hand, the installation and disassembly of the grinding disc is relatively cumbersome. When it is necessary to replace a grinding disc of a different type or a worn one, it often takes a lot of time and energy, affecting work efficiency; on the other hand, the existing grinding discs have poor heat dissipation during the grinding process, which can easily lead to excessive temperature of the grinding disc, which will not only reduce the service life of the grinding disc, but may also affect the grinding quality and even pose a safety hazard. In addition, the grinding angle of some grinding discs is fixed, which makes it difficult to meet the grinding needs of workpieces of different shapes and positions, and has poor flexibility in use. Summary of the Invention

[0003] In response to the above problems, the present invention provides a motor spindle grinder, which achieves quick installation and disassembly by optimizing the installation structure of the grinding disc; sets up an efficient heat dissipation structure to improve the heat dissipation performance of the grinding disc; and designs a device with adjustable grinding angle to improve the flexibility of the grinding disc to meet diverse grinding needs.

[0004] The technical solutions of the present invention are as follows:

[0005] A motor spindle grinder comprises a frame, a clamping device, a grinding mechanism and an intelligent control system, wherein the frame comprises a rigid frame and a workbench provided with a T-slot, the clamping device comprises a pneumatic three-jaw chuck and a servo-driven tailstock, the tailstock being connected to the servo motor via a linear guide rail, and the intelligent control system integrating a PLC, a pressure sensor and a process parameter database; the grinding mechanism comprises a grinding disc main body, which is detachably connected to a mounting seat; a plurality of heat dissipation holes are provided on the grinding disc main body, and the heat dissipation holes penetrate the upper and lower surfaces of the grinding disc main body; a protective edge is provided at the edge of the grinding disc main body, and the protective edge is inclined toward the outside of the grinding disc main body.

[0006] The working principle of the above technical solution is as follows:

[0007] The motor spindle grinder of the present invention arranges the grinding disc body and the mounting seat to be detachably connected, so that the grinding disc body can be quickly disassembled and installed when it needs to be replaced, thereby greatly improving work efficiency; the heat dissipation holes on the grinding disc body can accelerate air circulation, effectively take away the heat generated during the grinding process, reduce the temperature of the grinding disc body, and extend its service life; the angle adjustment unit can flexibly adjust the angle of the grinding disc body according to actual grinding needs, so that the grinding work can better adapt to workpieces of different shapes and positions; the protective edge arranged obliquely at the edge can prevent debris generated during the grinding process from splashing, thereby ensuring the safety of the operator.

[0009] In a further technical solution, the pneumatic three-jaw chuck of the clamping device has a built-in infrared radiation sensor for detecting the eccentricity of the spindle clamping, and triggering an audible and visual alarm when the eccentricity exceeds the tolerance.

[0010] In a further technical solution, an active shock-absorbing pad is provided at the bottom of the frame, and the shock-absorbing pad includes a rubber damping layer and a hydraulic adjustment mechanism, which can reduce the vibration amplitude of the equipment by ≥60%.

[0011] In a further technical solution, the heat dissipation holes are evenly distributed on the grinding disc body in a honeycomb shape. Compared with the traditional heat dissipation hole layout, the honeycomb distribution can increase the heat dissipation area to a greater extent and improve the heat dissipation efficiency.

[0012] In a further technical solution, the inclination angle of the protective edge is 30°-60°. Within this angle range, it can effectively prevent debris from flying without causing too much obstruction to the grinding work.

[0013] The beneficial effects of the present invention are:

[0014] 1. The card slot and card block are matched with the installation structure of the locking component to achieve rapid installation and disassembly of the grinding disc body, improve work efficiency, and ensure installation stability.

[0015] 2. The honeycomb-shaped heat dissipation holes on the main body of the grinding disc can effectively accelerate air circulation, reduce the temperature of the grinding disc, and improve the service life and grinding quality of the grinding disc.

[0016] 3. The angle adjustment unit can flexibly adjust the grinding angle of the grinding disc body. Combined with the angle scale mark, the grinding work can accurately adapt to the grinding needs of different workpieces; the protective edge can effectively prevent debris from flying and ensure the safety of the operator.

[0020] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0021] Example:

[0022] A motor spindle grinding machine, such as Figure 1 As shown, it includes a frame, a clamping device, a grinding mechanism and an intelligent control system. The frame includes a rigid frame and a workbench with T-slots. The clamping device is composed of a pneumatic three-jaw chuck and a servo-driven tailstock. The tailstock is connected to the servo motor through a linear guide. The intelligent control system integrates PLC, pressure sensor and process parameter database; the grinding mechanism includes a grinding disc main body 10, and the grinding disc main body 10 is detachably connected to a mounting seat 12; the grinding disc main body 10 is provided with a plurality of heat dissipation holes, and the heat dissipation holes pass through the upper and lower surfaces of the grinding disc main body 10; the mounting seat 12 is provided with an angle adjustment unit; a circle of protective edge 11 is provided at the edge of the grinding disc main body 10, and the protective edge 11 is inclined toward the outside of the grinding disc main body 10.

[0023] The working principle of the above technical solution is as follows:

[0024] The motor spindle grinder of the present invention is configured to have a detachable connection between the grinding disc body 10 and the mounting base 12. When the grinding disc body 10 needs to be replaced, it can be quickly disassembled and installed, thereby greatly improving work efficiency. The heat dissipation holes on the grinding disc body 10 can accelerate air circulation, effectively take away the heat generated during the grinding process, reduce the temperature of the grinding disc body 10, and extend its service life. The angle adjustment unit can flexibly adjust the angle of the grinding disc body 10 according to actual grinding needs, so that the grinding work can better adapt to workpieces of different shapes and positions. The protective edge 11 arranged obliquely at the edge can prevent debris generated during the grinding process from splashing, thereby ensuring the safety of the operator.

[0025] The motor spindle grinder of the present invention has a detachable mounting structure, which facilitates the quick replacement of the grinding disc body 10. The efficient heat dissipation design can reduce the temperature of the grinding disc and extend its service life. The adjustable grinding angle and protective edge 11 design improve the flexibility and safety of the grinding disc and meet diverse grinding needs.

[0026] In another embodiment, the angle adjustment unit includes a fixed seat 20, a rotating shaft 30 and an adjusting handle 31. The fixed seat 20 is fixedly mounted on the mounting seat 12. The rotating shaft 30 passes through the fixed seat 20 and the grinding disc body 10, and is rotatably connected to the fixed seat 20. One end of the rotating shaft 30 is fixedly connected to the grinding disc body 10; the adjusting handle 31 is fixedly connected to the other end of the rotating shaft 30. The adjusting handle 31 is provided with an angle scale mark 32. By rotating the adjusting handle 31, the rotating shaft 30 is driven to rotate, thereby realizing the adjustment of the angle of the grinding disc body 10. The fixed seat 20 is provided with an angle scale mark 32, which is convenient for the operator to accurately control the rotation angle of the grinding disc body 10.

[0027] In another embodiment, the fixing base 20 is provided with a slot 21, and the bottom of the grinding disc body 10 is provided with a block that matches the slot 21. The fixing base 20 is also provided with a locking assembly. The slot 21 and the block cooperate to achieve preliminary positioning, and then the locking assembly is used to reinforce and ensure the stability of the installation.

[0028] In another embodiment, the locking assembly includes a locking rod, a spring, and a button. The fixing base 20 is provided with a locking hole 22 that communicates with the card slot 21. The locking rod is slidably disposed in the locking hole 22. The spring is sleeved on the locking rod, with one end connected to the inner wall of the mounting base 12 and the other end connected to the locking rod. The button is fixed to one end of the locking rod and is located outside the mounting base 12. When the card block is inserted into the card slot 21, the button is pushed to insert the locking rod into the corresponding locking slot on the card block, and the spring is compressed, thereby locking the card block and the card slot 21. When disassembly is required, the button is pressed again, and under the elastic force of the spring, the locking rod is withdrawn from the locking slot, and the grinding disc body 10 can be removed.

[0029] In another embodiment, the heat dissipation holes are evenly distributed on the grinding disc body 10 in a honeycomb shape. Compared with the traditional heat dissipation hole layout, the honeycomb distribution can increase the heat dissipation area to a greater extent and improve the heat dissipation efficiency.

[0030] In another embodiment, the inclination angle of the protective edge 11 is 30° to 60°. Within this angle range, it can effectively prevent debris from flying without causing excessive obstruction to the grinding work.

[0031] The above-described embodiments merely represent specific implementations of the present invention.
