Description

Technical Field

[0001] This utility model relates to the field of mechanical grinding technology, and in particular to an automatic sand-repairing device for a grinding wheel machine. Background Technology

[0002] Grinding wheel dressing is an indispensable part of grinding operations. During grinding, the grinding wheel gradually wears and becomes dull, which affects the grinding effect. By dressing the grinding wheel, these worn and dull parts can be removed, restoring its grinding capability and allowing it to continue performing at its best. Additionally, grinding wheel dressing is also necessary when it becomes filled with metal shavings and cannot continue grinding.

[0003] In commercially available grinding machines, the grinding wheel is moved to the dressing device for dressing after the grinding is finished. Manual dressing is time-consuming and labor-intensive, and it requires alignment with the grinding surface of the grinding wheel, resulting in large precision errors and easy secondary wear of the grinding wheel. Utility Model Content

[0004] The purpose of this invention is to provide an automatic sand-repairing device for a grinding wheel machine to solve the problems encountered in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An automatic sand dressing device for a grinding wheel machine includes a housing and a sand dressing mechanism. A grinding wheel is installed on one side of the bottom of the housing and is driven to rotate by a drive device. The sand dressing mechanism is installed on the other side of the bottom of the housing, and a sand dressing component is installed at the working end of the sand dressing mechanism. The sand dressing component matches the working grinding surface of the grinding wheel. The housing has a linear conveying installation cavity inside, and a linear conveying device that is linearly connected to the sand dressing mechanism is installed in the linear conveying installation cavity.

[0007] In the above scheme, the linear conveying mounting cavity is installed on the top side near the sand-repairing mechanism, and the upper part of the outer body of the sand-repairing mechanism is provided with a slot; the working end of the linear conveying device is installed in the slot through a positioning block, and the linear conveying device is linearly connected to the outer body of the sand-repairing mechanism. As a preferred embodiment, the middle part of the outer body of the sand-repairing mechanism is provided with a sliding groove for achieving a smooth guiding effect, and the inside of the housing is provided with a clearance cavity, in which a guide slide plate that is slidably connected to the sliding groove is installed, and the guide slide plate is arranged parallel to the radial surface of the grinding wheel.

[0008] In the above scheme, the drive device is installed on the top of the chassis, and the output end of the drive device is connected to the drive shaft through a coupling. The working end of the drive shaft is fixedly connected to the grinding wheel through a clamping member.

[0009] In the above solution, the sand-cutting mechanism includes an outer body and a servo motor installed inside the outer body, the drive end of the servo motor being driven by the sand-cutting assembly. Further, the sand-cutting assembly includes a positioning element and a dressing disc, the dressing disc being driven by the positioning element and the drive end of the servo motor. As a preferred embodiment, a sleeve is installed in the inner hole of the dressing disc. As a preferred embodiment, the dressing disc has teeth on its outer surface that match the grinding wheel.

[0010] Compared with existing technologies, the advantages of this invention are as follows: By installing the sand dressing mechanism on the other side of the bottom of the machine housing, and installing a sand dressing component at the working end of the sand dressing mechanism, the sand dressing component matches the working grinding surface of the grinding wheel, allowing it to dress the worn working surface of the grinding wheel during operation. A linear conveyor mounting cavity is provided inside the machine housing, in which a linear conveyor device connected to the sand dressing mechanism via linear transmission is installed. Driven by the linear conveyor device, the sand dressing mechanism moves linearly by a certain small stroke, gradually approaching the grinding wheel according to its wear condition, performing minor grinding and dressing. This automatic sand dressing device can replace manual labor to complete the dressing of grinding wheels, with high work efficiency. Because the sand dressing component matches the working grinding surface of the grinding wheel, the dressing accuracy is also high, extending the service life of the grinding wheel and avoiding secondary wear caused by manual dressing.

[0019] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0020] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 and Figure 3 As shown, an automatic sand-repairing device for a grinding wheel machine includes a housing 1 and a sand-repairing mechanism 3. A grinding wheel 2 is mounted on one side of the bottom of the housing 1, and the grinding wheel 2 is driven to rotate by a drive device 21. Under the drive of the drive device 21, which is either a servo motor or an AC motor, the grinding wheel 2 rotates at high speed to grind the blanks of mechanical parts.

[0022] For specific implementation details, please refer to [link / reference]. Figure 2 The drive unit 21 is mounted on the top of the housing 1. The output end of the drive unit 21 is connected to the drive shaft 23 via a coupling 22. The coupling 22 provides self-aligning function for the transmission process, maintaining good transmission torque. The working end of the drive shaft 23 is fixedly connected to the grinding wheel 2 via a clamping member 24. The clamping member 24 mainly clamps the grinding wheel 2 through a grooved clamping surface, and fixes the grinding wheel 2 firmly by screws passing through the clamping surface.

[0023] The dressing mechanism 3 is installed on the other side of the bottom of the casing 1. The working end of the dressing mechanism 3 is equipped with a dressing component 33, which matches the working grinding surface of the grinding wheel 2, so that it can dress the worn working surface of the grinding wheel 2 during operation. The casing 1 is provided with a linear conveyor mounting cavity 11. A linear conveyor device (not shown in the figure) is installed in the linear conveyor mounting cavity 11 and is linearly connected to the dressing mechanism 3. The linear conveyor device can be a cylinder, hydraulic cylinder, or electric cylinder. Under the drive of the linear conveyor device, the dressing mechanism 3 moves linearly by a certain amount of stroke, especially according to the wear condition of the grinding wheel 2, so that it gradually approaches the grinding wheel 2 to perform micro-grinding and dressing of the grinding wheel 2.

[0024] In practical implementation, the linear conveying installation cavity 11 is installed on the top side near the sand-repairing mechanism 3. Please refer to [link / reference]. Figure 4 The outer body 31 of the sand-repairing mechanism 3 has a slot 36 on its upper part. The slot 36 can be a rectangular slot, a circular slot, or even a polygonal slot, all of which can facilitate connection. The working end of the linear conveyor is installed in the slot 36 via a positioning block, and the linear conveyor is linearly connected to the outer body of the sand-repairing mechanism 3. The positioning block is connected to the working end of the linear conveyor via a self-aligning device such as a coupling. The structure of the positioning block matches the slot 36 and is inserted into the slot 36 to facilitate the overall movement of the outer body 31 of the sand-repairing mechanism 3. Because the wear allowance of the outer circle of the grinding wheel 2 is small, only a small movement is required in this design, such as 0.1 mm each time.

[0025] To facilitate the linear drive of the linear conveyor, a groove is provided in the middle of the outer body 31 of the sand-repairing mechanism 3 for smooth guidance. The housing 1 has an internal clearance cavity 13, within which a guide slide plate 12, slidably connected to the groove, is installed. The guide slide plate 12 is parallel to the radial surface of the grinding wheel 2. Under the linear drive of the linear conveyor, the outer body 31 of the sand-repairing mechanism 3 moves slightly along with the sand-repairing assembly 33. The groove and guide slide plate 12 guide this slight movement of the outer body 31, bringing it closer to the outer working end of the grinding wheel 2, so that the outer surface of the grinding wheel 2 can be repaired by the sand-repairing assembly 33.

[0026] The sand-cutting mechanism 3 includes an outer body 31 and a servo motor 32 installed inside the outer body 31. The drive end of the servo motor 32 is connected to the sand-cutting assembly 33, thereby driving the sand-cutting assembly 33 to rotate, and thus grinding the grinding wheel 2. Please refer to [link to relevant documentation]. Figure 4 The dressing assembly 33 includes a positioning element 34 and a dressing disc 35. The dressing disc 35 plays a major role in dressing the grinding wheel 2. The dressing disc 35 is connected to the drive end of the servo motor 32 through the positioning element 34. After the positioning element 34 passes through the inner hole of the dressing disc 35, it fixes the dressing disc 35 to the working end of the servo motor 32. It is a detachable installation.

[0027] As a preferred option, please refer to Figure 5 A sleeve 37 is installed in the inner hole of the dressing disc 35. The inner diameter of the sleeve 37 remains constant, while the outer diameter is changed according to different specifications of the dressing disc 35 to match the inner hole of different specifications of the dressing disc 35. In addition, the dressing disc 35 has teeth 38 on its outer surface that match the grinding wheel 2. The teeth 38 are V-shaped or W-shaped grooves, used to match the shape of the grinding wheel 2 to grind and dress the worn outer cylindrical surface of the grinding wheel 2. When dealing with different models of grinding wheels 2, different models of dressing discs 35 can also be adjusted to adapt to the outer cylindrical surface that needs to be ground and repaired.
