Furthermore, a particular feature, structure, or characteristic may be combined in any manner in one or more embodiments.

[0036] In the following description, in order to clearly demonstrate the structure and working method of this utility model, a number of directional terms will be used. However, terms such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and not as limiting terms.

[0037] Reference Figures 1 to 3 This utility model provides a multi-angle end face chamfering machine, including a worktable 1, a grinding wheel 2, a movable plate 3, and an angle ruler 4.

[0038] The grinding wheel 2 is rotatably mounted on the rear side of the worktable 1. The movable plate 3 is located in front of the grinding wheel 2 and can slide on the worktable 1 in the back-and-forth direction. The angle gauge 4 is rotatably mounted on the movable plate 3 and can be locked onto the movable plate 3 by the locking member 41.

[0039] In use, the processing angle of product 9 can be determined by rotating the angle ruler 4. After determining the angle, the angle ruler is locked to the movable plate 3 by the locking member 41. Pushing the movable plate 3 to move backward causes the angle ruler and product 9 to move backward as well, so that the rear end of product 9 slowly approaches the grinding wheel surface of grinding wheel 2 for end face grinding, chamfering and multi-angle chamfering.

[0040] This invention achieves precise angle adjustment and improves machining accuracy through the combined use of the movable plate 3 and the angle gauge 4. (Refer to...) Figure 4 (a) to Figure 4 (e) This utility model is applicable to the grinding, chamfering and multi-angle chamfering of the end faces of various products of suitable size, including various workpieces, products of various materials and cutting tools, etc., with a wide coverage.

[0041] In one embodiment, a guide rail 11 is provided on the left or right side of the worktable 1, and the length direction of the guide rail 11 is the front-to-back direction. A slider is provided on the left or right side of the movable plate 3, and the slider is slidably connected to the guide rail 11.

[0042] In one embodiment, a positioning hole is provided on the movable plate 3 near the rear side of the grinding wheel 2, and a pin 42 passes through the angle ruler 4 and is rotatably connected to the positioning hole, thereby realizing the rotatable connection between the angle ruler 4 and the movable plate 3.

[0043] In one embodiment, the angle ruler 4 is an angle ruler 4 with a 90-degree semi-circular groove. A locking nut is provided on the angle ruler 4, and the locking member 41 is a pentagonal screw. The angle ruler 4 is locked by the pentagonal screw passing through the 90-degree semi-circular groove from top to bottom and tightening it with the locking nut.

[0044] The locking nut on the angle gauge 4 can be located at the top or bottom of the 90-degree semi-circular groove, preferably at the bottom. That is, a locking nut is located at the bottom of the angle gauge 4. A pentagonal screw passes through the 90-degree semi-circular groove from top to bottom and is threaded into the locking nut. When the pentagonal screw abuts against the movable plate 3, it locks the angle gauge 4. When it is necessary to rotate the angle gauge 4, the pentagonal screw is loosened from the locking nut.

[0045] This example demonstrates how locking or releasing the angle gauge 4 via locking element 41 ensures accuracy and repeatability during the machining process.

[0046] In one embodiment, the angle ruler 4 is a 90-degree angle ruler 4 with a vertical edge.

[0047] The vertical edge of angle gauge 4 can be used to align and abut against the side of the product perpendicular to the grinding wheel surface. For example, Figure 3 As shown, the right side of the vertical edge is aligned with and abuts against the side of the product perpendicular to the grinding wheel surface.

[0048] In one embodiment, the multi-angle end face chamfering machine also includes a water injection pipe 5 and a drain outlet 6.

[0049] One end of the water injection pipe 5 is connected to an external water supply device, and the other end of the water injection pipe 5 faces the grinding wheel 2 behind the angle ruler 4. The drain outlet 6 is located on the workbench 1 and runs through the top and bottom of the workbench 1.

[0050] Water injection pipe 5 injects water into the contact area between grinding wheel 2 and product 9. This water injection reduces heat generated by friction, extending the service life of grinding wheel 2. Drain outlet 6 promptly removes excess cooling water to prevent impact on processing results and maintain a safe and clean working environment.

[0051] Specifically, a water storage tank can be installed below the workbench 1, with a drain outlet 6 located above and connected to the water storage tank. The cooling water discharged from the drain outlet 6 can flow directly into the water storage tank. Alternatively, a drain pipe can be connected to the drain outlet 6 to discharge the cooling water into a sewer or other drainage system.

[0052] In this embodiment, a water injection switch, such as a valve, can be installed on the water injection pipe 5 or the external water supply device to open the water injection switch to inject water when water injection is required.

[0053] In one embodiment, a water-blocking steel strip 7 is provided on the movable plate 3. The water-blocking steel strip 7 runs through the top and bottom of the movable plate 3. The length direction of the water-blocking steel strip 7 is the front-to-back direction. The water-blocking steel strip 7 is located on the side away from the water injection pipe 5.

[0054] In this embodiment, the control plate 3 moves in the front-to-back direction by manually pulling the lower half of the water-blocking steel bar 7, while the upper half of the water-blocking steel bar 7 blocks water, simplifying the design and improving efficiency.

The machine platform side baffle is disposed on the side of the worktable 1 and is connected to the machine platform baffle.

[0056] The water baffle plate 8 of this utility model prevents cooling water from splashing.

[0057] In one embodiment, the multi-angle end face chamfering machine further includes a drive motor, the motor shaft of which is connected to the grinding wheel 2, and the grinding wheel 2 is driven to rotate by the drive motor.

[0058] Specifically, the drive motor can be located behind the grinding wheel 2, and can be covered by a dust cover. The motor shaft of the drive motor extends out of the dust cover and is connected to the grinding wheel 2 in front of it. The motor shaft can be supported on the worktable 1 by bearings.

[0059] In one embodiment, the multi-angle end face chamfering machine also includes a power supply voltage control box 12 and a machine switch 13.

[0060] The power supply voltage control box 12 has a built-in voltage regulator, which is connected to the power supply terminal of the drive motor. The machine switch 13 is connected between the voltage regulator and the power supply terminal of the drive motor.

[0061] The operating voltage of the drive motor can be adjusted by the voltage regulator to adapt to different processing requirements, thus improving the machine's adaptability and reliability. The start and stop of the drive motor can be controlled by the machine switch 13.

[0062] In this embodiment, the voltage regulation device can be any existing device used for regulating the voltage of a motor or for adjusting the power of a motor.

[0063] In one embodiment, when using this utility model, the side of the product 9 perpendicular to the end face to be processed is aligned with the vertical edge of the angle ruler 4 on the movable plate 3. After adjusting the angle ruler 4 to a suitable angle, the locking part 41 is tightened.
