[0002] A desktop CNC machine tool is a compact CNC machine tool that can be placed on a desktop. It is generally easier to operate and move than larger CNC machines, and is relatively affordable and easy to use. Common types of desktop CNC machines include bench grinders, milling machines, lathes, and drilling machines. Different types of grinders offer different processing methods and precision.
[0003] Among them, when using a bench grinder, the material is usually ground with a grinder first, and then a detector is used to press the stylus against the surface of the material and slowly rotate the material to complete the detection of the roughness of the material surface.
[0004] However, when testing the roughness of materials, due to the presence of some granular contaminants on the material surface, the test results may be inaccurate during the test process, and in severe cases, the stylus of the detector may be damaged. Therefore, it is necessary to provide a desktop CNC machine tool to solve the above problem.

[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this 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 present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.
[0032] like Figure 1-Figure 2 As shown, the present application provides a desktop CNC machine tool, specifically a desktop grinder, comprising a base 1, with fixed frames 13 fixedly mounted on the upper ends of both sides of the base 1, a first adjustment mechanism 14 being transversely disposed on one side of the fixed frame 13, a second adjustment mechanism 15 being longitudinally disposed on a side of the first adjustment mechanism 14 away from the fixed frame 13, a sharpening group 16 being fixedly mounted on the other side of the second adjustment mechanism 15, the sharpening group 16 comprising a reduction motor mounted on the second adjustment mechanism 15, and a sharpening member fixed on the output shaft of the reduction motor;
[0033] It should be noted that the second adjustment mechanism 15 is used to longitudinally adjust the sharpening group 16, and the first adjustment mechanism 14 is used to laterally adjust the second adjustment mechanism 15 and the sharpening group 16. In this application, the first adjustment mechanism 14 and the second adjustment mechanism 15 are existing motor ball screw structures. For details, please refer to relevant literature and will not be repeated here.
[0034] In addition, an electric three-jaw chuck 11 is fixedly installed on the upper end of the base 1, and the electric three-jaw chuck 11 is located below the grinding group 16. The electric three-jaw chuck 11 is used to fix the material to be ground. The electric three-jaw chuck 11 is a prior art and will not be described here. At the same time, a top plate 12 is provided on the opposite side of the electric three-jaw chuck 11. The top plate 12 is internally threaded with a rotating column (not shown in the figure). By rotating the rotating column, it can be pressed against the other end of the material to prevent the other end of the material from shaking during grinding.
[0035] At the same time, a detector 2 is also provided at the upper end of the base 1. In this application, the detector 2 is a roughness detector in the prior art. The detector 2 has a stylus. The stylus of the detector 2 and the sharpening group 16 are located on the same axis, and the height of the detector 2 is consistent with the height of the electric three-jaw chuck 11. In order to facilitate the adjustment of the position of the detector 2, a moving mechanism 3 is provided at the lower end of the detector 2. The moving mechanism 3 has a third adjustment mechanism 31 fixed to the upper end of the base 1. The third adjustment mechanism 31 is also an existing motor ball screw structure, which will not be described in detail here.
[0036] In the present application, a mounting plate 32 is provided at the upper end of the third adjustment mechanism 31 . It should be noted that the third adjustment mechanism 31 is used to drive the mounting plate 32 to move laterally.
[0037] like Figure 2-Figure 3 As shown, a slide groove 33 is provided at the upper end of the mounting plate 32, and a matching block is installed at the lower end of the detector 2, through which the detector 2 can be slidably connected to the slide groove 33. At the same time, a first cylinder 34 is provided at the end of the detector 2 away from the stylus, and the first cylinder 34 is fixed on the mounting plate 32, and the output shaft of the first cylinder 34 is fixed on the detector 2. Therefore, starting the first cylinder 34 can drive the detector 2 to move in the slide groove 33 toward the sharpening group 16 until it is against the material clamped by the electric three-jaw chuck 11, and then the detection is carried out.
[0038] At the same time, a cleaning mechanism 4 is also provided at the upper end of the detector 2. The cleaning mechanism 4 has an extension plate 41 fixedly mounted on the upper end of the detector 2 on the side with the stylus. A placement shell 42 is fixedly mounted on the other end of the extension plate 41. The placement shell 42 does not protrude from the stylus of the detector 2, and an opening is provided on the end of the placement shell 42 away from the detector 2.
[0039] In addition, the placement shell 42 is slidably connected to one end thereof close to the detector 2 with a push rod 43, and the push rod 43 protrudes from the placement shell 42. A scraper 44 is obliquely fixed at one end of the push rod 43 located in the placement shell 42, and the scraper 44 is higher than the opening of the placement shell 42, so it is convenient to enter and exit the placement shell 42. At the same time, a push block 45 is fixedly installed at the other end of the push rod 43, and the push block 45 is slidably connected to the extension plate 41. A second cylinder 46 is fixedly installed at the upper end of the detector 2, and the output shaft of the second cylinder 46 is fixed on the push block 45. Therefore, starting the second cylinder 46 can push the push block 45 to slide on the extension plate 41, thereby driving the push rod 43 and the scraper 44 to move outward, away from the placement shell 42.
[0040] In summary: after the part is polished and before the material roughness is tested, the second cylinder 46 is activated to push the push block 45 to slide on the extension plate 41, while the push rod 43 and the scraper 44 move outward until they are attached to the surface of the material. At this time, the polished material continues to rotate slowly along with the electric three-jaw chuck 11, and the scraper 44 cleans the particulate contaminants on the material surface.
[0041] Then the second cylinder 46 is retracted, and the rotation of the electric three-jaw chuck 11 is stopped at the same time. The first cylinder 34 is then driven to push the detector 2 outward against the material surface. Then the third adjustment mechanism 31 is started to drive the stylus of the detector 2 to slide gently across the material surface, sense the roughness of the surface being tested, amplify and output the signal, and complete the test. Therefore, during the process of testing the material surface, it will not be affected by some particulate contaminants on the material surface, thereby improving the test results and preventing damage to the stylus of the detector 2.
[0042] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
