Description

Technical Field

[0001] This utility model relates to the field of CNC machining equipment technology, and in particular to a grinding device for mechanical CNC electromechanical processing. Background Technology

[0002] During the machining process of CNC grinding machines, the grinding rollers rotate at high speed and come into contact with the workpiece, generating a large amount of frictional heat. To ensure machining accuracy and extend the service life of the grinding rollers, cutting fluid is needed to cool and lubricate them. Generally, the cutting fluid nozzles on CNC grinding machines are of a fixed design, with the cooling point typically being the grinding area of ​​the roller. The cutting fluid cannot cover the entire roller, resulting in insufficient heat dissipation. To reduce production costs, CNC grinding machines are usually equipped with a cutting fluid circulation and recovery system. However, in actual operation, after the cutting fluid has been used, its cooling and lubrication performance will decrease, and directly applying it to the grinding area will affect the grinding effect of the rollers. Utility Model Content

[0003] This invention addresses the problem of insufficient heat dissipation caused by fixed cooling points of the cutting fluid in grinding rollers. It proposes a grinding equipment for CNC electromechanical processing that recycles the used cutting fluid for auxiliary heat dissipation of the grinding rollers.

The two chucks are located on opposite sides of the workspace, and the workpiece is positioned between them. A grinding roller is mounted on the worktable and rotatably connected to it. The side of the grinding roller is the grinding surface. Two cutting fluid pipes are mounted on the worktable, with their outlets located above the grinding roller on opposite sides. The two cutting fluid pipes are a first cutting fluid pipe and a second cutting fluid pipe. The first cutting fluid pipe rinses the grinding side of the grinding roller, and its inlet is connected to a cutting fluid tank. The second cutting fluid pipe rinses the opposite grinding side of the grinding roller, and its inlet is connected to the outlet of a filter. The inlet of the filter is connected to a collection tank for collecting the cutting fluid in the workspace.

[0006] Preferably, a liquid collection tank is provided below the working space, and a flow plate is provided inside the liquid collection tank. The flow plate is fixedly connected to the machine tool body and has flow holes for the cutting fluid to pass through.

[0007] Preferably, the bottom of the collection tank is inclined, and a collection hopper is connected to the lowest point of the bottom of the collection tank. The collection hopper is used to connect the collection tank and the inlet end of the filter.

[0008] Preferably, the inlet end of the first cutting fluid pipe is provided with a first hose, which is used to connect the first cutting fluid pipe and the cutting fluid tank, and the inlet end of the second cutting fluid pipe is provided with a second hose, which is used to connect the second cutting fluid pipe and the filter.

[0009] Preferably, the workbench is provided with a first support and a second support, the first support being used to install a first cutting fluid pipe and the second support being used to install a second cutting fluid pipe.

[0010] Preferably, the workspace is provided with one horizontal support frame and two vertical support frames. The two vertical support frames are respectively installed on both sides of the workspace, and the horizontal support frame is located between the two vertical support frames. The horizontal support frame and the vertical support frames are slidably connected in the longitudinal direction, and the worktable is slidably connected to the horizontal support frame in the transverse direction.

[0011] Preferably, the two chucks are rotatably connected to the machine tool body, and the machine tool body is equipped with an adjusting cylinder. The adjusting cylinder is used to connect one of the chucks to the machine tool body and to adjust the distance between the two chucks.

[0013] 1. This CNC machining grinding equipment is used for grinding shaft or tube workpieces. The grinding roller contacts the side of the workpiece to perform the grinding work. Cutting fluid pipes are provided on the two grinding sides of the grinding roller. The cutting fluid pipes on the grinding side are connected to the cutting fluid tank, which can guide the cutting fluid to the grinding side of the grinding roller to achieve the rinsing of the grinding side of the grinding roller. The cutting fluid pipes on the opposite grinding side are connected to the filter, which can guide the recovered and filtered cutting fluid to the opposite grinding side of the grinding roller to achieve the rinsing of the grinding side of the grinding roller, thereby achieving auxiliary cooling of the grinding roller and improving the cooling effect of the grinding roller.

The adjusting cylinder 71 is fixedly installed on the machine tool body 1, and its end is rotatably connected to the chuck 7. The adjusting cylinder 71 can adjust the distance between the two chucks 7 for clamping workpieces of different lengths.

[0025] refer to Figure 3The side of the grinding roller 4 is the grinding surface. The grinding roller 4 is rotatably connected to the worktable 3. A first motor 10 is fixedly installed on one side of the worktable 3. The output shaft of the first motor 10 is connected to the end of the grinding roller 4. The first motor 10 is used to drive the grinding roller 4 to rotate, so as to realize the grinding work of the grinding roller 4. The rotation center of the grinding roller 4 and the clamping center of the chuck 7 are located on the same plane.

[0026] Furthermore, the worktable 3 is equipped with two cutting fluid pipes, namely a first cutting fluid pipe 8 and a second cutting fluid pipe 9. A first support 31 and a second support 32 are provided on the top of the worktable 3, located on different sides of the worktable 3. The first support 31 is used to mount the first cutting fluid pipe 8, and the second support 32 is used to mount the second cutting fluid pipe 9.

[0027] The outlets of the first cutting fluid pipe 8 and the second cutting fluid pipe 9 are located above the grinding roller 4, respectively. (Reference) Figure 4 The outlet of the first cutting fluid pipe 8 is provided with a first spray nozzle 81, which is located above the grinding side of the grinding roller 4. The outlet of the second cutting fluid pipe 9 is provided with a second spray nozzle 91, which is located above the opposite grinding side of the grinding roller 4.

[0028] The machine tool body 1 is equipped with a cutting fluid tank 15, and a first hose 82 is provided at the inlet end of the first cutting fluid pipe 8. The first hose 82 is used to connect the first cutting fluid pipe 8 and the cutting fluid tank 15. The cutting fluid tank 15 is filled with cutting fluid. The cutting fluid can be guided into the first cutting fluid pipe 8 by the pump body to rinse the grinding side of the grinding roller 4, cool the grinding area of ​​the workpiece, and wash away the machining chips.
