DETAILED DESCRIPTION

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0032] like Figure 1-Figure 7 As shown, the present application provides a force-controlled grinding tool, including a grinding assembly 10 and a support assembly 20 disposed on one side of the grinding assembly 10, wherein the support assembly 20 is used to place the workpiece material to be ground. At the same time, the support assembly 20 needs to have sufficient bearing capacity to ensure that it can stably support workpieces of various weights, sizes and shapes, and the grinding assembly 10 is used to grind the workpiece placed by the support assembly 20, so that the workpiece can be processed into a suitable requirement.

[0033] The grinding assembly 10 includes a bottom frame 11, on which a base 12 is fixedly mounted, on which a joint cantilever 13 is movably mounted, the joint cantilever 13 is composed of multiple sections, and multiple joint sections of the joint cantilever 13 are fixedly mounted with a motor a14, which is used to drive the joint cantilever 13, so that the joint cantilever 13 can achieve flexibility and operability, and can accurately grind workpieces of various shapes and positions.

[0034] A grinding wheel 16 is fixedly installed at the end of the articulated cantilever 13, and the grinding wheel 16 can contact the workpiece. At the same time, the grinding wheel 16 is driven by one of the motors a14, so that when the grinding wheel 16 is close to the workpiece, the workpiece can be ground. The grinding wheel 16 can select suitable materials or models according to different grinding requirements, such as grinding wheels, sandpaper, oilstones, grinding discs, etc.

[0035] A hanger 15 is fixedly installed on the grinding wheel 16, and the hanger 15 can ensure the stability of the grinding wheel 16. Usually, a certain vibration will be generated when the grinding wheel 16 is in use. These vibrations will not only affect the grinding accuracy and quality, but also have an adverse effect on the service life of the equipment. Therefore, the vibration energy can be absorbed by the hanger 15, thereby reducing the transmission and amplification of the vibration, allowing the equipment to operate in a relatively stable state, improving the grinding accuracy and quality, and extending the service life of the equipment.

[0036] The support assembly 20 includes a support frame 21 , and the support frame 21 is located on the grinding wheel 16 . A workbench 22 is fixedly mounted on the support frame 21 , and the workbench 22 is used to place a workpiece to be processed.

The pressure plate 225 can contact the workpiece on the workbench 22, and the nut is rotated on the threaded rod 226, so that the pressure plate 225 can be adjusted, and then the pressure plate 225 can be close to the workpiece and fixedly clamped, so that the stability of the workpiece on the workbench 22 can be guaranteed, thereby preventing the workpiece from shaking when being processed by the grinding wheel 16, and preventing the shaking or displacement of the workpiece during the grinding process from affecting the grinding quality and even causing safety accidents.

[0038] The pressing plate 225 is provided with a rectangular groove 227, so that the pressing plate 225 can move left and right, so that the pressing plate 225 can clamp workpieces in different situations. At the same time, the pressing plate 225 can change its position by adjusting the nut, so that the pressing plate 225 can fix workpieces of different thicknesses.

[0039] At the same time, a roller 224 is provided at the bottom of the slider 223, and the roller 224 contacts the inner bottom of the slide groove 221, so that when the slider 223 slides in the slide groove 221, the roller 224 will roll in the slide groove 221, so that the slider 223 can be quickly adjusted in the slide groove 221, thereby improving the smoothness of use of the slider 223 and also improving the use efficiency of the slider 223.

[0040] The workbench 22 is provided with a ventilation slot 222 near the slide slot 221, and a baffle 214 is fixedly installed inside the support frame 21. The baffle 214 is located at the bottom of the workbench 22, so that the debris generated by the grinding wheel 16 when processing the workpiece can pass through the ventilation slot 222 and then be partially collected by the baffle 214, thereby ensuring the cleaning effect of the equipment.

[0041] A dust collector 27 is provided at the bottom of the workbench 22. The dust collector 27 can be aligned with the workpiece and can be connected to an external power supply. When the dust collector 27 is turned on, the debris generated by the grinding wheel 16 can be sucked into the dust collector 27, thereby effectively preventing the debris and dust from diffusing in the air, thereby significantly improving the air quality in the working area.

[0042] An adjustment mechanism is provided at the bottom of the support frame 21, which can move the position of the dust collector 27 so that the dust collector 27 can be at different positions at the bottom of the workbench 22, so that the materials on the workbench 22 can be aligned when placed at different positions, so that the dust collector 27 can efficiently absorb the material debris at these different positions.

[0043] The adjustment mechanism includes a slide rail a23, which is located at the bottom of the workbench 22. A motor b25 is fixedly installed on the support frame 21. A screw rod a24 is fixedly installed on the output end of the motor b25. The screw rod a24 is rotatably connected to the slide rail a23. A slide seat 26 is threadedly connected to the screw rod a24. The slide seat 26 is fixedly connected to the bottom of the dust collector 27. The slide seat 26 is slidably installed on the slide rail a23, so that the screw rod a24 can be opened, so that the screw rod a24 will rotate inside the slide rail a23, and the slide seat 26 can be adjusted on the slide rail a23. At this time, the dust collector 27 can achieve the effect of adjusting the direction to the left and right.

[0044] A slide rail b28 is fixedly installed on the support frame 21, and a motor c29 is fixedly installed on the slide rail b28. A screw rod b210 is fixedly installed on the output end of the motor c29. A fixed block 211 is threaded on the screw rod b210. The fixed block 211 is slidably installed on the slide rail b28, and the fixed block 211 is fixedly connected to the motor b25. The fixed block 211 is used to support the motor b25, so that the motor c29 can be turned on to drive the screw rod b210 to rotate inside the slide rail b28, so that the fixed block 211 can be adjusted on the slide rail b28. At this time, the motor b25 together with the slide rail a23 can adjust the direction forward and backward. The dust collector 27 can be adjusted forward, backward, left and right by the adjustment mechanism, so that the dust collector 27 can be in different positions at the bottom of the workbench 22 as needed.

[0045] A limit rod 212 is fixedly installed on the other end of the support frame 21, and a limit ring 213 is slidably installed on the limit rod 212. The limit ring 213 is fixedly connected to the end of the slide rail a23. Therefore, when the slide rail a23 is adjusted by the slide rail b28, the limit ring 213 will slide on the limit rod 212, so that the slide rail a23 can be supported, and the stability of the slide rail a23 can be guaranteed during adjustment.
