Description

Technical Field

[0001] This utility model relates to the field of surface grinders, specifically a surface grinder dressing tool. Background Technology

[0002] Surface grinders are a type of grinding machine used to grind flat or shaped surfaces of workpieces. They are widely used for grinding the end faces of parts. The main types include horizontal-spindle rectangular tables, horizontal-spindle rotary tables, vertical-spindle rectangular tables, and vertical-spindle rotary tables. In existing technology, surface grinders mainly consist of a grinding wheel, a worktable, and a fixture mounted on the worktable for holding the workpiece. After the workpiece is clamped and fixed by the fixture, it can be driven to move linearly back and forth relative to the grinding wheel on the worktable, thereby grinding the end face of the workpiece. Grinding wheels are prone to damage after a period of use, and damaged grinding wheels need to be repaired. Current grinding wheel repair methods involve grinding with diamond grinding heads.

[0003] For example, patent CN220279333U discloses a grinding wheel dresser for a surface grinder, including a base and a slide connected to the base. Support leg one and support leg two are respectively provided on both sides of the upper end of the slide. Support leg one and support leg two are fixedly connected to the upper end of support leg one and support leg two. Fixing block two is fixedly connected to the inner end of the support. Fixing block two is rotatably connected to the mounting plate. A through hole is provided in the middle of the mounting plate. A diamond pen is slidably placed in the through hole. A push rod is fixedly connected to the tail end of the diamond pen.

[0004] The mounting plate of the aforementioned patent can rotate relative to the fixed block two to adjust the dressing angle of the diamond dressing tool, enabling dressing of the grinding wheel from multiple angles. It has a wider range of applications and scenarios, is more convenient to operate and adjust, saves installation and debugging time, and can bring better dressing results. However, the disadvantage of the aforementioned patent is that during the dressing operation, the grinding wheel dresser needs to be attached to the magnetic table of the machine tool to dress the grinding wheel. After dressing, the magnetic table switch needs to be turned off before it can be removed. The up and down adjustment of the dresser is laborious.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0028] The ball screw 5 includes a screw 501 and a screw nut 502 that are configured to cooperate, and the screw 501 is rotatably disposed inside the screw mounting hole 4.

[0029] Specifically, the front and rear ends of the lead screw 501 are rotatably mounted inside the screw mounting hole 4 via the second bearing 404 and the first bearing 401, respectively.

[0030] A first bearing 401 is fixedly installed at the rear end of the screw mounting hole 4. A first step portion 402 and a first internal thread portion 403 are provided on the inner wall of the front end of the screw mounting hole 4. The first step portion 402 is located behind the first internal thread portion 403. A second bearing 404 is installed at the first step portion 402. A plug 405 is threadedly connected at the first internal thread portion 403.

[0031] In this design, the rear end of the outer ring of the second bearing 404 abuts against the first stepped portion 402, and the front end of the outer ring of the second bearing 404 abuts against the plug 405.

[0032] The front end of the lead screw 501 passes through the plug 405 and is fixedly connected to the crank handle 503;

[0033] Specifically, the plug 405 has a through hole 406 in the middle for the front end of the lead screw 501 to pass through; at the same time, in order to facilitate screwing the plug 405 into the first internal thread 403, the front end of the plug 405 is also provided with a hexagonal head 407 to facilitate turning the plug 405.

[0034] The movable block 6 has a nut mounting hole 601 on its left side, and the lead screw nut 502 is fixedly installed in the nut mounting hole 601. At the same time, in order to restrict the movement path of the movable block 6 and enable the movable block 6 to move back and forth along the movable groove 3, a guide groove 602 is also provided on the right side of the movable groove 3. The guide groove 602 is set along the front and back direction, and a guide block 603 is provided on the right side of the movable block 6, which is slidably set in the guide groove 602.

[0035] When using this utility model, such as Figure 9 As shown (it should be known, Figure 9 This is not a complete schematic diagram of a surface grinder, but only a partial structural schematic diagram, showing only the column, slide, and grinding wheel box of the surface grinder; it should not be construed as representing the complete structure of the surface grinder in this solution. Figure 9The illustration is for illustrative purposes only and is not intended to indicate or imply that the device or component referred to must have a specific construction and operation, and therefore should not be construed as a limitation or misinterpretation of the present invention. The surface grinder is mounted on the slide 9 of the surface grinder via a mounting base. At this time, the mounting housing 2 is located on the top of the grinding wheel box 8 of the surface grinder. The top of the grinding wheel box 8 is slotted, and the diamond pen 7 passes through the slot to contact the grinding wheel inside the grinding wheel box 8. When in use, the crank handle 503 is turned (forward and reverse), which drives the movable block 6 through the ball screw 5, thereby driving the diamond pen 7 to move back and forth, and thus dressing the arc side wall of the grinding wheel of the surface grinder.
