[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: the grinding wheel dressing machine moves the grinding block by means of a slide rail, which is not very stable in actual operation. When the grinding wheel is rotating at high speed during dressing, the grinding block is prone to deviation due to factors such as vibration, which affects the dressing quality. Furthermore, it cannot be flexibly adjusted according to actual dressing needs and cannot meet the diverse requirements of grinding wheel dressing processes.

[0005] Therefore, those skilled in the art have provided a grinding wheel dressing machine with a blocking structure to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grinding wheel dressing machine with a blocking structure. Through the worm and worm wheel, the position of the grinding block can be easily adjusted, and the side of the grinding wheel body can be dressed, thus improving the versatility and applicability of the equipment.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A grinding wheel dressing machine with a blocking structure includes a base, an adjustment mechanism at the upper end of the base, a rotating plate, a worm gear rotatably mounted on one side of the rotating plate, a lead screw rotatably mounted inside the rotating plate, a slider threadedly connected to the lead screw, a worm wheel fixedly mounted at the front end of the lead screw, an electric telescopic rod fixedly mounted at the upper end of the slider, a mounting block fixedly mounted at the output end of the electric telescopic rod, and a grinding block fixedly mounted at the rear end of the mounting block by multiple bolts.

[0009] A limit block is slidably provided on one side of the base, and two limit grooves are formed on the outer surface of the rotating plate near the limit block.

[0010] Furthermore, the worm gear is meshed with the worm wheel, and the lower end of the rotating plate is rotatably mounted on the upper end of the base.

[0011] Furthermore, the slider is externally slidably disposed inside the rotating plate, and the limiting block is slidably disposed inside one of the two limiting grooves on the side near the rotating plate.

[0012] Furthermore, a guide rod is fixedly provided at the upper end of the slider, and the front end of the worm gear is rotatably disposed inside the front end of the rotating plate.

[0013] Furthermore, the guide rod is fixedly provided with scale lines on its exterior, and the mounting block is slidably disposed on the exterior of the guide rod.

[0014] Furthermore, a motor is fixedly mounted on the upper end of the base, and a grinding wheel body is fixedly mounted on the output end of the motor by bolts.

[0015] Furthermore, a protective frame is slidably provided on the upper end of the base, and two transparent plates are fixedly provided on the outer surface of the protective frame.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model proposes a grinding wheel dressing machine with a blocking structure. When it is necessary to dress the side of the grinding wheel body, the limiting block is pulled to disengage it from the limiting groove. Then, the rotating plate is rotated. When the rotating plate rotates to the set position, the limiting block is pushed. The limiting block slides inside the base and inserts into another limiting groove, thereby limiting the rotating plate. Subsequently, the worm gear is rotated to drive the grinding block to approach and contact the side of the grinding wheel body, thereby achieving the dressing of the side of the grinding wheel body. Thus, the position of the grinding block relative to the grinding wheel body can be changed according to actual needs, improving the adaptability of the grinding wheel dressing machine to different dressing needs and making the operation more flexible and diverse.

[0018] 2. This utility model proposes a grinding wheel dressing machine with a blocking structure. When dressing the grinding wheel body, rotating the worm gear drives the worm wheel to rotate, which in turn causes the lead screw to rotate, causing the slider to slide. This results in the grinding block gradually approaching and contacting the grinding wheel body. Furthermore, the output end of the electric telescopic rod can adjust the position of the grinding block according to the actual dressing requirements, realizing the dressing operation of the grinding wheel body. Moreover, the self-locking characteristics of the worm wheel and worm gear can effectively prevent the lead screw from rotating accidentally during the dressing process, improving the dressing quality. The protective frame can effectively prevent the debris from the grinding wheel body flying out during the dressing process from causing injury to personnel. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-5 One embodiment provided by this utility model:

[0028] A grinding wheel dressing machine with a blocking structure includes a base 1. An adjustment mechanism 6 is provided on the upper end of the base 1. The adjustment mechanism 6 includes a rotating plate 606. A worm gear 607 is rotatably provided on one side of the rotating plate 606. A lead screw 605 is rotatably provided inside the rotating plate 606. A slider 604 is threadedly connected to the lead screw 605. A worm wheel 609 is fixedly provided at the front end of the lead screw 605. An electric telescopic rod 603 is fixedly provided at the upper end of the slider 604. An installation block 602 is fixedly provided at the output end of the electric telescopic rod 603. A grinding block 601 is fixedly provided at the rear end of the installation block 602 by multiple bolts.

[0029] A limiting block 2 is slidably installed on one side of the base 1, and two limiting grooves 608 are opened on the outer surface of the rotating plate 606 near the limiting block 2;

[0030] The worm 607 is meshed with the worm wheel 609. The lower end of the rotating plate 606 is rotatably mounted on the upper end of the base 1. The slider 604 is slidably mounted inside the rotating plate 606. The limiting block 2 is slidably mounted inside one of the two limiting grooves 608 on the side near the rotating plate 606. The upper end of the slider 604 is fixedly mounted with a guide rod 8. The front end of the worm wheel 609 is rotatably mounted inside the front end of the rotating plate 606. The guide rod 8 is fixedly mounted with a scale line 7. The mounting block 602 is slidably mounted inside the guide rod 8. The upper end of the base 1 is fixedly mounted with a motor 3. The output end of the motor 3 is fixedly mounted with a grinding wheel body 5 by bolts. The upper end of the base 1 is slidably mounted with a protective frame 4. Two transparent plates 9 are fixedly mounted on the outer surface of the protective frame 4.

[0031] Specifically, when dressing the surface of the grinding wheel body 5, the grinding wheel body 5 is first securely installed on the output end of the motor 3 using bolts to ensure a firm connection. Then, the motor 3 is started, and the output end of the motor 3 drives the grinding wheel body 5 to rotate at high speed, providing grinding power for the subsequent dressing work. At this time, the operator rotates the worm 607. Since the worm 607 is meshed with the worm wheel 609, the rotation of the worm 607 will cause the worm wheel 609 to rotate, which in turn drives the lead screw 605 fixed at the front end of the worm wheel 609 to rotate smoothly inside the rotating plate 606. Since the lead screw 605 is threadedly connected to the slider 604, the rotation of the lead screw 605 will drive the slider 604 to rotate smoothly. 04. The screw 605 slides precisely along the axis inside the rotating plate 606, eventually driving the grinding block 601 mounted on the slider 604 to gradually approach and contact the grinding wheel body 5. At the same time, the electric telescopic rod 603 can flexibly and precisely adjust the position of the mounting block 602 and the grinding block 601 connected to its output end according to the actual dressing requirements, thereby realizing the precise dressing operation on the surface of the grinding wheel body 5. In addition, the guide rod 8 is provided with a scale line 7. The mounting block 602 slides on the guide rod 8. The operator can accurately know the moving distance of the mounting block 602 and the grinding block 601 by observing the scale line 7, so as to achieve more precise control of the dressing amount.

[0032] During the dressing process, to ensure the safety of the operator, simply push the protective frame 4 so that its lower end slides smoothly along the upper end of the base 1. When the protective frame 4 slides to the appropriate position, it can effectively block the debris that splashes during the dressing process of the grinding wheel body 5, avoiding injury to the operator and providing reliable safety protection for the operator. In addition, its external transparent plate 9 makes it convenient for the operator to observe the dressing process, improving the convenience of operation.

[0033] When it is necessary to trim the side of the grinding wheel body 5, the limiting block 2 is pulled to slide inside the base 1, thereby completely disengaging it from the current limiting groove 608. Then, the rotating plate 606 can be pulled to rotate around the rotation connection point with the base 1. When the rotating plate 606 rotates to the set position that meets the side trimming requirements, the limiting block 2 is pushed again to slide inside the base 1 until the limiting block 2 is inserted into another limiting groove 608, thereby achieving a firm limit on the rotating plate 606. Subsequently, by rotating the worm gear 607, the grinding block 601 is driven to approach and contact the side of the grinding wheel body 5, thereby achieving precise trimming of the side of the grinding wheel body 5.

[0034] The position of the grinding block 601 can be easily adjusted by rotating the worm gear 607. With the fine adjustment of the electric telescopic rod 603, the grinding block 601 can be quickly and accurately moved to the ideal dressing position, which improves the operator's work efficiency, reduces the difficulty of operation, and can meet the diverse grinding wheel dressing process requirements, thus improving the versatility and applicability of the equipment. Moreover, the worm gear 609 and the worm 607 have a self-locking function, which can effectively prevent the lead screw 605 from rotating accidentally, ensuring the stability of the position of the grinding block 601 and guaranteeing the stability of the dressing quality.

[0035] Working principle: When dressing the grinding wheel body 5, the grinding wheel body 5 is fixed to the output end of the motor 3 with bolts. Then, the motor 3 is started to drive the grinding wheel body 5 to rotate. At this time, by rotating the worm 607, since the worm 607 is meshed with the worm wheel 609, the rotation of the worm 607 will drive the worm wheel 609 to rotate, causing the lead screw 605 to rotate inside the rotating plate 606, so that the slider 604 threaded to it slides inside the rotating plate 606, so that the grinding block 601 approaches and contacts the grinding wheel body 5. In addition, the output end of the electric telescopic rod 603 adjusts the position of the mounting block 602 and the grinding block 601 according to the actual dressing requirements, so as to realize the precise dressing operation of the grinding wheel body 5. By pushing the protective frame 4, its lower end slides on the upper end of the base 1. When it slides to the appropriate position, the protective frame 4 can prevent the debris flying during the dressing of the grinding wheel body 5 from injuring people.

[0036] Secondly, when it is necessary to trim the side of the grinding wheel body 5, first pull the limiting block 2 so that it slides inside the base 1. The sliding of the limiting block 2 disengages from the limiting groove 608. At this time, pull the rotating plate 606 so that it rotates on the base 1. When the rotating plate 606 rotates to the set position, push the limiting block 2 so that it slides inside the base 1. The sliding of the limiting block 2 will insert into another limiting groove 608 to limit the rotating plate 606. Then, by rotating the worm gear 607, the grinding block 601 can be moved closer to and contact the side of the grinding wheel body 5, thereby trimming the side of the grinding wheel body 5.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
