Description

Technical Field

[0001] The utility model relates to the technical field of dressing machine tools, in particular to a dressing machine tool for grinding wheel processing. Background Art

[0002] The dressing machine for diamond grinding wheel processing is a kind of precision mechanical equipment specially used for dressing diamond grinding wheels. Its main function is to accurately dress the diamond grinding wheel through the precision-controlled dressing tool to maintain the shape, dimensional accuracy and surface roughness of the working surface of the grinding wheel, and ensure the efficient and stable operation of the diamond grinding wheel in the subsequent grinding operation.

[0003] The existing dressing machine for grinding wheel processing is provided with a moving unit that can move horizontally, and a replacement mechanism is provided on the moving unit, so that in the process of using different dressers to dress the grinding wheel, when the dresser needs to be replaced, the pressing units on both sides can be squeezed, and the pressing units push the clamping units out of the fixed block, and the clamping units are inserted into the plug plate to compress the spring, and then the dresser is pulled, so that the dresser drives the plug plate to pull out the fixed block, and then the replaced dresser drives the plug plate to be inserted into the fixed block, and after the plug plate is inserted, the clamping unit pops out and is inserted into the fixed block for fixing. When the grinding wheel is dressed, the dresser can be quickly replaced according to needs, which effectively improves the dressing efficiency;

[0004] However, in the above operation, the operator needs to continuously apply pressing force to overcome the friction and limiting resistance between the trimmer and the equipment. This process not only consumes a lot of physical strength, but also takes a long time to operate, resulting in low efficiency in trimmer replacement, which is not conducive to improving production efficiency. In addition, since the removal path of the trimmer directly depends on the stability of the pressing force and direction applied by the operator, once the operator's force or direction control is inaccurate, it may cause the trimmer to deviate from the ideal trajectory.

[0005] Therefore, it is necessary to provide a new grinding wheel processing dressing machine to solve the above-mentioned technical problems. Utility Model Content

Telescopic grooves are respectively opened on both sides of the insert plate. Telescopic members and sliding blocks are sequentially arranged in the telescopic grooves from the inside to the outside.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] In the specific implementation process, Figures 1 to 5 As shown, the dressing machine for grinding wheel processing includes a base 1, a mobile unit 2 is arranged on the base 1, and a connecting plate 3 and a dresser 7 are arranged on the top of the mobile unit 2 in sequence from bottom to top, the connecting plate 3 is fixedly connected to the mobile unit 2, sliding grooves 12 are respectively provided on both sides of the connecting plate 3, and an extrusion column 4 is slidably connected in the sliding groove 12, and a fixed block 5 is fixedly connected to the extrusion column 4, and the connecting plate 3 is also provided with a placement groove 13 and a limiting groove 14 for limiting the fixed block 5, the bottom of the dresser 7 is embedded in the rectangular through groove opened on the connecting plate 3, and limiting members that can extend into the sliding groove 12 of the connecting plate 3 are respectively arranged on both sides of the dresser 7, and auxiliary handrails 6 are respectively fixedly connected at both ends of the outer side of the extrusion column 4 away from the fixed block 5, and the outer side of the auxiliary handrail 6 is bent toward the direction of the connecting plate 3, thereby expanding the contact area and facilitating subsequent use by the operator.

[0023] It should be understood from the above scheme that, first, an appropriate squeezing force pointing in the direction of the limiter is applied to the squeezing column 4, so as to cause relative movement between the squeezing column 4 and the limiter, so that the limiter gradually withdraws from the sliding groove 12. As the squeezing column 4 is advanced, the placement groove 13 originally embedded in the fixed block 5 for limiting the axial rotation of the squeezing column 4 gradually loses its restraining effect and begins to slide smoothly along the sliding groove 12 until it is completely separated from the placement groove 13. When the fixed block 5 is completely separated from the placement groove 13 and enters the sliding groove 12, the squeezing column 4 obtains the condition for free rotation along the axis. As the squeezing column 4 continues to advance forward, the limiter is subjected to greater pressure, further shrinks and stores elastic potential energy. When the pressure reaches a certain threshold, the limiter completely separates from the sliding groove 12, eliminating the obstruction to the removal path of the trimmer 7. At the same time, the fixed block 5 moves along The sliding groove 12 slides smoothly and finally reaches the bottom position of the limiting groove 14. The operator applies a rotational force along the axial direction of the extrusion column 4 to rotate the extrusion column 4 together with the fixed block 5. The fixed block 5 moves accurately along the internal track of the limiting groove 14 during the rotation process and finally reaches the position of the limiting groove 14. The elastic potential energy accumulated by the limiting member due to the previous contraction begins to be released, and a reverse extrusion force is generated on the extrusion column 4. This extrusion force causes the fixed block 5 to fit tightly with the inner wall of the limiting groove 14, thereby firmly limiting the extrusion column 4 in the horizontal direction. In order to ensure that the trimmer 7 can be taken out smoothly and without hindrance, the above-mentioned operations need to be performed synchronously on the limiting members on both sides of the trimmer 7. After the limiting members on both sides are successfully contracted and separated from the sliding groove 12, the trimmer 7 will completely release all horizontal limits, and the operator can easily take it out.

[0024] Thus, by adopting the above arrangement, it is only necessary to apply an appropriate squeezing force once to start the contraction and separation process of the limiter, and then it is only necessary to rotate the squeezing column 4 to complete the positioning of the fixing block 5, thereby ensuring the accurate movement and positioning of the fixing block 5 during the removal process, avoiding the stagnation or damage of the trimmer 7 caused by human operation errors, and ensuring that the trimmer 7 is smoothly and accurately separated from the equipment. The whole process is labor-saving and efficient, which significantly reduces the burden on the operator and shortens the replacement time of the trimmer 7.

[0025] In the scenario of mass production or frequent replacement of the trimmer 7, the fixing device of the equipment significantly speeds up the replacement of the trimmer 7, reduces non-production time, thereby improving the overall production efficiency, helping enterprises to reduce costs and improve competitiveness.

[0026] like Figures 2 to 4As shown, the limiter includes a plug plate 8, which is fixedly connected to the bottom of the trimmer 7, and the plug plate 8 is placed in a rectangular through groove provided on the connecting plate 3, and telescopic grooves are respectively provided on both sides of the plug plate 8, and the telescopic grooves are sequentially provided with telescopic members and sliding blocks 9 from the inside to the outside, and the telescopic members can drive the sliding block 9 to extend to the sliding groove 12 of the connecting plate 3, and the plug plate 8 is also provided with connecting grooves located on the upper and lower sides of the telescopic groove, and the upper and lower ends of the sliding block 9 are respectively fixedly connected to the limiter blocks 10, and the outer side wall of the limiter block 10 is fitted with the connecting groove of the plug plate 8, and the telescopic member is a telescopic spring 11, and one side of the telescopic spring 11 is fixedly connected to the telescopic groove of the plug plate 8, and the end of the telescopic spring 11 away from the telescopic groove is fixedly connected to the sliding block 9, and the bottom cross section of the sliding block 9 near the end of the extrusion column 4 is arranged in an arc shape;

[0027] It should be understood from the above scheme that the bottom cross-section of the sliding block 9 is arranged in an arc shape. When the plug plate 8 is docked with the rectangular through groove of the connecting plate 3, the top wall of the through groove of the connecting plate 3 exerts a downward squeezing force on the arc-shaped part of the sliding block 9. Due to the arc-shaped design, this squeezing force guides the sliding block 9 to move into the telescopic groove. In the process of the sliding block 9 moving into the telescopic groove, the limit block 10 moves synchronously with the sliding block 9 in the connecting groove, and always keeps in contact with the sliding block 9 and slides along the trajectory of the connecting groove. This movement trajectory of the limit block 10 ensures that the sliding block 9 can only move in the horizontal direction, effectively preventing it from deflecting during the docking process, and realizing horizontal limitation. As the sliding block 9 moves into the telescopic groove, the telescopic spring 11 is squeezed by the sliding block 9 and gradually compressed, storing elastic potential energy. This part of energy will In the subsequent steps, it is used to drive the sliding block 9 to return to its original position to ensure its precise positioning. When the fixed block 5 of the extrusion column 4 is in the placement groove 13 position, a space for the sliding block 9 to enter is formed inside the sliding groove 12. At this time, the extrusion force of the connecting plate 3 on the sliding block 9 gradually disappears, and the sliding block 9 quickly rebounds under the action of the elastic potential energy of the telescopic spring 11, enters the sliding groove 12 along the telescopic groove, and fits with one side of the extrusion column 4. The sliding block 9 entering the sliding groove 12, its side surface is tightly fitted with the inner wall of the sliding groove 12 to form a stable contact surface, thereby effectively limiting the sliding block 9 in the vertical direction. At the same time, the elastic potential energy of the telescopic spring 11 continues to act on the sliding block 9, so that it maintains a fit state with one side of the extrusion column 4, doubly ensuring the vertical stability of the sliding block 9 inside the sliding groove 12.
