Description

Technical Field

[0001] The utility model relates to a multi-station grinding transition tool bar and a grinding device, belonging to the technical field of mechanical processing. Background Art

[0002] Mechanical grinding is a manufacturing process that uses abrasive particles coated or pressed on the grinding tool to perform finishing processing on the machined surface through the relative movement of the grinding tool and the workpiece under a certain pressure. It is used to adjust and improve the size and surface quality of mechanical parts. Grinding is mainly used for important parts that require high precision and low surface roughness.

[0003] At present, when using the grinding tools for the radial outer circle (upper guide bearing mating surface) and axial flange mirror (upper and lower thrust bearing mating surfaces) of the thrust head in the upper bearing of the main pump motor, the supplier configures two sets of tool bars for different stations for the grinding tools, which are used for radial outer circle grinding and axial plane grinding respectively. Therefore, when switching the processing position, it is necessary to first disassemble the previous tool bar and install the tool bar matching the new station, which is cumbersome, resulting in low processing efficiency and increased production costs.

[0023] The utility model is described in detail below in conjunction with the accompanying drawings.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] A multi-station grinding transition tool bar, such as Figure 1-3 As shown, it comprises a tool bar body 1, a connection portion 13 connected to a machine tool is provided on the rear portion of the tool bar body 1, and a vertical clamping portion 11 and a horizontal clamping portion 12 are provided on the front portion of the tool bar body 1.

[0026] Specifically, by using a multi-station grinding transition tool bar, the grinding tool is directly clamped at the vertical clamping part 11 and the horizontal clamping part 12. The position of the grinding tool can be quickly changed without stopping the machine to replace the tool bar, thereby reducing manual workload, reducing non-production time, and improving production efficiency and cutting efficiency. Not only can the time and labor cost of replacing the tool bar be reduced, but also the production cost and quality problems caused by errors and inconsistencies in the clamping positions between different tool bars can be avoided. In the description of the embodiment of the utility model, it should be understood that the term "front" refers to the direction of the workpiece, and the term "rear" refers to the direction of the machine tool. The vertical clamping part 11 and the horizontal clamping part 12 at the front can facilitate the processing of the workpiece after the grinding tool is clamped, and the connection part 13 at the rear can be conveniently connected to the machine tool.

[0027] As another specific embodiment, the vertical clamping portion 11 is a vertical clamping hole arranged in the vertical direction; and / or, the horizontal clamping portion 12 is a horizontal clamping hole arranged in the front-rear direction. The vertical clamping hole and the horizontal clamping hole can be used to place the handle of the grinding tool. By arranging the handle along the horizontal clamping hole, the tool head of the grinding tool faces downward, and the axial flange surface of the workpiece is processed; and by arranging the handle along the vertical clamping hole, the tool head of the grinding tool faces forward, and the radial outer circle of the workpiece is processed.

[0028] As another specific embodiment, the vertical clamping hole and the horizontal clamping hole are both square holes with the same size. The square holes can be matched with the square handle, and the circumferential structure between the handle and the square hole can interfere with each other through the directional matching structure, so as to prevent the handle from rotating circumferentially.

[0029] As another specific embodiment, a fastening hole 14 extending to the right is provided on the left side of the tool bar body 1, the fastening hole 14 is perpendicular to the axis of the vertical clamping hole and the horizontal clamping hole, and the fastening hole 14 is connected with the vertical clamping hole or the horizontal clamping hole, and a set screw is provided in the fastening hole 14. The tool handle can be fixed by the fastening hole 14 and the set screw, so as to prevent the quality problem caused by the axial movement of the grinding tool and improve the stability of the processing.

[0030] As another specific implementation, the fastening holes 14 include five, and the five fastening holes 14 are distributed in a "cross" shape. In this way, the set screws can be evenly distributed on the side of the shank body 1.

[0031] As another specific implementation, the connecting portion 13 is a clamping connecting section, which enables the machine tool to clamp the tool bar through the clamping connecting section, thereby connecting the tool bar to the machine tool.

[0032] As another specific embodiment, there is a bending transition portion 15 between the front and rear portions of the tool bar body 1, and the tool bar body 1 is viewed from above as an inverted L-shaped block; the vertical clamping portion 11 and the horizontal clamping portion 12 are arranged at the lateral ends of the L-shape, and the connecting portion 13 is the vertical portion of the L-shape. Since the tool head of the grinding tool is arranged on one side of the tool handle, the vertical clamping portion 11 and the horizontal clamping portion 12 can be offset to one side together with the tool handle through the arrangement of the bending transition portion 15, thereby making the center of the tool clamping position of the machine tool and the workpiece clamping position as close as possible, which is convenient for program writing and control.

[0033] As another specific embodiment, the knife bar body 1 is provided with a lifting hole 16 which is arranged through the knife bar body 1 from top to bottom. The lifting hole 16 can facilitate the transportation of the knife bar body 1.

[0034] As another specific embodiment, the hoisting hole 16 is provided on the right side of the vertical clamping portion 11 and the horizontal clamping portion 12. Since the fastening hole 14 is provided on the right side of the vertical clamping portion 11 and the horizontal clamping portion 12, the connecting portion 13 needs to be connected to the machine tool, and in order to prevent interference with other structures and hoisting balance, the hoisting hole 16 is provided on the right side of the vertical clamping portion 11 and the horizontal clamping portion 12.

[0035] A grinding device comprises a machine tool, wherein the machine tool is connected with a tool bar body 1, and a grinding tool on the tool bar body 1 is detachably connected to a vertical clamping part 11 or a horizontal clamping part 12.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The present invention is extended to any new features or any new combination disclosed in this specification, and any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.

[0037] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.
