[0029] The following further elaborates on the present utility model according to the attached drawings and embodiments.

[0030] In this specification, the orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc., which are mentioned or may be mentioned, are defined with respect to the structures shown in the respective drawings. The terms "inside" and "outside" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may accordingly change depending on their different positions and usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0031] This embodiment provides a vertical spindle surface grinder. Referring to Figures 1 to 4 , it includes a base 1 and a workbench 2 arranged on the base 1. The workbench 2 is used to position the workpiece to be ground. A column 6 is positioned on the side of the base 1. A grinding device 3 is provided at the top of the column 6, and its grinding end can perform vertical lifting relative to the workbench 2 to perform rotary grinding on the surface of the workpiece. The workbench 2 is slidably connected to the base 1 through a sliding mechanism 4. The sliding mechanism 4 includes a sliding seat 41 and a guide rail 42 that are slidably connected. The sliding seat 41 is fixedly connected to the bottom of the workbench 2. The guide rail 42 is arranged on the base 1 and is located below the bottom surface of the workbench 2. A driving device 8 is also provided on the base 1. The driving device 8 is used to drive the workbench 2 to slide on the guide rail 42. At the same time, blocking mechanisms 5 are respectively provided at both ends of the workbench 2 along the moving direction. The blocking mechanisms 5 are used to block the flying grinding debris at both ends of the moving direction of the workbench 2, avoiding the flying grinding debris from splashing onto the surface of the guide rail 42 and affecting the guiding accuracy of the guide rail 42, thereby maintaining the machining accuracy of the grinder.

[0032] It should be noted that referring to Figure 1 , since the guide rail 42 is located below the workbench 2, the part of the guide rail 42 that is slidably connected to the sliding seat 41 is covered by the workbench 2, that is, the grinding debris generated during the grinding process can only splash onto the guide rail 42 from both ends of the workbench 2 along the moving direction. Therefore, it is only necessary to provide the blocking mechanisms 5 at both ends of the workbench 2 along the moving direction.

[0033] Further, the blocking mechanism 5 includes a horizontally arranged receiving plate 51 and a vertically arranged blocking plate 52. One end of the receiving plate 51 is connected to the workbench 2, and the other end is connected to the blocking plate 52. The blocking plate 52 has a certain height in the vertical direction, blocking the splashing grinding debris and preventing the grinding debris from splashing onto the guide rail 42 from both ends of the moving direction of the workbench 2, and the grinding debris can be collected by the receiving plate 51.

[0034] Meanwhile, a spacing distance is provided between the workbench 2 and the blocking plate 52 by arranging the receiving plate 51, that is, the grinding debris will not fall onto the workbench 2 after being blocked by the blocking plate 52, ensuring the cleanliness of the workbench 2.

[0035] After the surface grinder performs long-term grinding processing, a large amount of debris will accumulate on the receiving plate 51. At this time, to prevent the grinding debris accumulated on the receiving plate 51 from falling, it is necessary to regularly clean the grinding debris on the receiving plate 51. Therefore, the receiving plate 51 is detachably connected to the workbench 2. When cleaning the grinding debris on the receiving plate 51, the receiving plate 51 can be detached from the workbench 2, facilitating the cleaning of the grinding debris.

[0036] In this embodiment, the grinding device 3 includes a housing 31, a grinding head 32 rotatably connected to the bottom of the housing 31, and a rotating motor �3 positioned inside the housing 31 for driving the grinding head 32 to rotate. The output shaft of the rotating motor 33 is connected to the grinding head 32. One end of the housing 31 is slidably connected to the column 6, and a lifting mechanism 7 for driving the housing 31 to vertically lift on the column 6 is provided on the column 6. The lifting mechanism 7 includes a lifting motor 71 and a lead screw 72. The lifting motor 71 is fixed near one end of the column 6 close to the base 1. The lead screw 72 is vertically arranged. One end of the lead screw 72 is drivingly connected to the lifting motor 71, and the other end is connected to the housing 31 through a nut sleeve. During operation, the lifting motor 71 drives the lead screw 72 to rotate, thereby driving the housing 31 connected to the lead screw 72 to vertically lift relative to the workbench 2. During this period, the rotating motor 33 drives the grinding head 32 to rotate to perform rotary grinding on the surface of the workpiece.

[0037] In this embodiment, at least one set of sliding surfaces are formed on the slide block 41. The slide block 41 is in abutting contact with the surface of the guide rail 42 through the sliding surfaces and constitutes a sliding connection. The driving device 8 is a telescopic hydraulic cylinder. The movable end of the telescopic hydraulic cylinder is connected to the slide block 41. During operation, the driving device 8 drives the slide block 41 to move relative to the base, so that the workpiece on the workbench 2 moves horizontally away from or close to the grinding device 3, and then the workpiece is ground on the base 1. And the driving device 8 is located below the workbench 2 and is arranged in the same direction as the guide rail 42, which can prevent the grinding debris from splashing onto the driving device 8 and helps to improve the service life of the driving device 8.

[0038] In this embodiment, a protective cover 9 is provided on the base 1. The protective cover 9 is installed on the periphery of the base 1. A space for accommodating the workbench 2 and the grinding device 3 is formed between the protective cover 9 and the surface of the base 1, so that both the workbench 2 and the grinding device 3 can be located inside the protective cover 9. The setting of the protective cover 9 can effectively isolate the splashes generated during grinding inside the protective cover 9, preventing them from splashing onto the staff and thus protecting the staff from harm. At the same time, an opening conforming to the size of the workpiece is provided on the protective cover 9 to ensure that the workpiece can smoothly enter and exit the protective cover 9 during grinding.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
