Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheel marking, in particular to a grinding wheel marking clamping mechanism. Background Art

[0002] Grinding wheels are the most important type of abrasive tools in grinding processing. Grinding wheels are porous bodies made by adding binders to abrasives, pressing, drying and sintering. Due to the differences in abrasives, binders and manufacturing processes, the characteristics of grinding wheels vary greatly, which has an important impact on the processing quality, productivity and economy of grinding.

[0003] When using an infrared laser marking machine to mark grinding wheel products, first turn on the red light, move the product on the marking plane to align the red light, and then mark it after finding the correct position. The red light alignment time required before each marking is too long, which seriously wastes time. In addition, during the marking process, the grinding wheel needs to be moved continuously, and the movement must be uniform and in the same direction to ensure perfect marking, resulting in low marking efficiency and affecting the efficiency of grinding wheel production.

[0004] For example, an infrared laser marking machine for grinding wheel production disclosed in Chinese patent CN212350790U is provided. The base is a cylindrical solid structure, and a circular plate is coaxially fixedly connected to the upper end of the base. A vertical positioning column is welded at the axis position of the upper end surface of the circular plate. The housing of the servo motor is welded to the lower end surface of the circular plate. A rotating device is provided on the base, and the rotating device includes an annular sleeve. An annular groove is provided on the side wall of the base. The rotating device is provided, and the grinding wheel is fixed by utilizing the structural characteristics that most grinding wheels are circular and have a through hole in the center. The infrared laser head is driven by clicking to make a circular motion to mark the grinding wheel in a fixed position, which changes the previous way of moving the grinding wheel. For grinding wheels of the same specifications and sizes, there is no need to align the position again after alignment once, which saves a lot of alignment time, thereby improving the marking efficiency.

[0005] However, in the prior art, when the center of the grinding wheel is positioned by a cylinder, it is not suitable for centering and fixing grinding wheels of various sizes, thereby affecting the marking efficiency in the production process of the grinding wheel.

[0006] For this reason, we urgently need to provide a grinding wheel marking clamping mechanism. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0028] Embodiment 1:

[0029] A grinding wheel marking clamping mechanism comprises a supporting leg 1, a clamping structure is installed on the top of the supporting leg 1, a collecting structure is installed on the bottom of the clamping structure, and a marking structure is connected to the top of the clamping structure.

[0030] The clamping structure includes a clamping unit and an adjusting unit. The clamping unit includes a workbench 201. Positioning plates 202 are installed at the left and right ends of the middle of the top surface of the workbench 201. The positioning plate 202 is internally connected to an electric push rod 203. The output end of the electric push rod 203 is connected to a connecting plate 204. The end of the connecting plate 204 away from the electric push rod 203 is connected to a spring 205. The end of the spring 205 away from the connecting plate 204 is connected to a clamping seat 206. A clamping block 209 is arranged on the left side of the clamping seat 206. The adjusting unit includes an adjusting block 207. A threaded hole is opened in the middle of the front of the adjusting block 207. A bidirectional threaded rod 208 is threadedly connected to the threaded hole.

[0031] The unthreaded parts at one end of the front and back sides of the outer surfaces of the bidirectional threaded rod 208 are rotatably connected to the circular holes provided in the middle of the front and back sides of the clamping seats 206. The outer surface of the adjustment block 207 is slidably connected to the convex groove provided in the middle of one side close to the two clamping seats 206. The clamping block 209 is fixedly connected to the adjustment block 207.

[0032] By setting the clamping structure, the electric push rod 203 is started to drive the connecting plate 204, the spring 205, and the clamping seat 206 to move, thereby driving the clamping block 209 to clamp the grinding wheel. When clamping, the mutual balance between the deformation stresses of the spring 205 is used to achieve the center positioning clamping of the grinding wheel. At the same time, the two-way threaded rod 208 can be rotated to adjust the distance between the adjustment block 207 and the clamping block 209, which is suitable for clamping grinding wheels of various sizes.

[0033] When the grinding wheel is clamped and fixed, the grinding wheel is placed on the top surface of the workbench 201, and then the electric push rod 203 is synchronously started to drive the connecting plate 204, the spring 205, and the clamping seat 206 to move, so that the clamping block 209 is close to the grinding wheel, and then the two-way threaded rod 208 is rotated, and the threaded connection between the two-way threaded rod 208 and the adjusting block 207 is used to adjust the spacing of the adjusting block 207, thereby effectively adjusting the spacing of the clamping block 209, which is suitable for clamping grinding wheels of different sizes. Afterwards, when the electric push rod 203 is started to drive the clamping block 209 to clamp the grinding wheel, the balance generated by the deformation stress between the springs 205 can be used to make the grinding wheel in a center positioning state, thereby better marking the grinding wheel.

[0036] The collection structure includes a collection box 301, an air pump 302 is connected to the back of the collection box 301, a filter plate 303 is installed near the back end of the collection box 301, a collection drawer 304 is installed at the bottom of the collection box 301 near the front end, an adsorption tube 305 is connected to the middle of the front of the collection box 301, and a dust hopper 306 is connected to the end of the adsorption tube 305 away from the collection box 301. The bottom surface of the dust hopper 306 is fixedly connected to the middle of the top surface of the workbench 201 near the front side, the outer surface of the collection drawer 304 is sealed and slidably connected to the inner wall of a rectangular hole opened at the right bottom of the collection box 301 near the front end, and the outer surface of the filter plate 303 is sealed and slidably connected to the inner wall of a rectangular through hole opened at the right end of the collection box 301 near the back.

[0037] By setting the collection structure, the air inside the collection box 301 is pumped by starting the air pump 302, and the negative pressure state inside the collection box 301 can be used to adsorb and collect the debris generated by marking through the adsorption tube 305 and the dust hopper 306, and the collection drawer 304 is used to collect and uniformly process them. By setting the marking structure, the two electric push rods 104 are adjusted separately, so that the slider 106 can drive the longitudinal rod 107 or the cross rod 109 to move, so that the mounting block 108 slides along the outer surface of the longitudinal rod 107 or the cross rod 109, so as to adjust the position of the marking component 110, thereby effectively improving the accuracy of marking.

[0038] When marking the grinding wheel, by adjusting the two sets of electric push rods 104 respectively, the slider 106 can drive the longitudinal rod 107 and the cross rod 109 to move respectively, so that the mounting block 108 can slide horizontally along the outer surface of the longitudinal rod 107 or the cross rod 109, thereby realizing the X-axis and Y-axis movement of the mounting block 108 on the horizontal plane, thereby driving the mounting block 108 and the marking component 110 to move precisely, so as to achieve more accurate marking of the grinding wheel. During the marking process, the air pump 302 is started to pump the air inside the collection box 301, so that the inside of the collection box 301 is in a negative pressure state, and the air pressure is used to make the debris enter the adsorption tube 305 and the collection box 301 through the dust hopper 306. After the debris enters the collection box 301, it falls into the collection drawer 304 after being blocked by the filter plate 303. By pulling out the collection drawer 304, it is convenient to centrally process the debris.
