Description

Technical Field

[0001] This utility model relates to the technical field of diamond processing equipment, specifically to a multi-wheel superhard tool grinding machine. Background Technology

[0002] With the rapid development of aerospace, automotive, and energy industries, a large number of high-performance new materials are emerging, such as silicon-aluminum alloys and fiber-reinforced composite materials. The processing requirements of these materials have driven the development of superhard cutting tools. Superhard cutting tools are tools made from superhard materials with significantly higher hardness than traditional tool materials such as cemented carbide. Currently, the main materials for superhard cutting tools include single-crystal diamond, polycrystalline diamond (PCD), polycrystalline cubic boron nitride (PCBN), and chemical vapor deposition (CVD) diamond. These materials possess extremely high hardness and wear resistance and are widely used in high-speed cutting and advanced manufacturing technologies.

[0003] In the production and processing of superhard cutting tools, the grinding device is one of the key pieces of equipment. Traditional grinding devices can generally only perform rough grinding or fine grinding of the tool. That is, after rough grinding of the workpiece, the workpiece must either be removed and loaded onto a fine grinding device for finishing, or the grinding disc (grinding wheel) for fine grinding must be replaced before continuing the fine grinding process. Regardless of the method used, the workpiece or grinding disc needs to be reloaded during actual operation; this greatly increases the processing time of superhard cutting tools and reduces production efficiency. Therefore, this application aims to provide a multifunctional grinding machine tool that can be used to perform both rough and fine grinding of cutting tools, and the workpiece only needs to be loaded once, saving time and improving efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and provide a multi-wheel superhard tool grinding machine that can be used to simultaneously perform rough grinding and fine grinding of superhard tools, and the workpiece only needs to be loaded once, thereby improving processing efficiency.

[0005] The technical solution of this utility model is: a multi-wheel superhard tool grinding machine, including a bed, a grinding mechanism and a clamping mechanism. The clamping mechanism is located on one side of the bed and includes a workpiece table and a tool holder. The tool holder is located on the workpiece table and is used to drive the tool holder to move. The tool holder is used to clamp the tool to be processed. The grinding mechanism is located on the other side of the bed and is slidably connected to the bed. The grinding mechanism includes a base and multiple grinding heads.

[0006] Furthermore, each of the plurality of grinding heads includes a drive spindle and a grinding wheel.

[0007] Furthermore, the bed is equipped with a slide rail, and a sliding component is provided below the base of the grinding mechanism. Through the cooperation of the sliding component and the slide rail, the base of the grinding mechanism is restricted to move along the direction of the slide rail.

[0008] Furthermore, a lifting mechanism is provided on the upper surface of the base, and one of the multiple grinding heads is mounted on the lifting mechanism. The lifting mechanism can be a lifting cylinder, a lead screw mechanism, etc.

[0009] Furthermore, a water-blocking mechanism is provided between the grinding mechanism and the clamping mechanism. The water-blocking mechanism includes a fixed frame and a water-blocking plate, with the water-blocking plate slidably installed in the fixed frame.

[0010] Furthermore, the baffle plate is fixedly connected to the base, and the base drives the baffle plate to move within the fixed frame.

[0011] Furthermore, the baffle plate is provided with a vertical through groove. The end of the drive spindle of the grinding head mounted on the lifting mechanism passes through the through groove and is connected to a flange. The grinding wheel of the grinding head mounted on the lifting mechanism is mounted on the flange. The drive spindle drives the flange to rotate, thereby causing the grinding wheel to rotate.

[0012] Furthermore, the grinding head mounted on the lifting mechanism includes two grinding wheels; the two grinding wheels have different diameters and are coaxially arranged on the flange, and both the inner and outer surfaces of the two grinding wheels can be used for grinding.

[0013] Furthermore, grinding heads are also fixedly installed on the water baffle, and there can be multiple grinding heads on the water baffle.

[0014] Furthermore, the workpiece stage can be used to drive the tool holder to perform translational movements in the X and Y directions and rotational movements in the Z-axis direction. The workpiece stage can adopt an integrated structure or combined mechanism that can achieve the corresponding functions in the existing technology. For example, it can be an organic combination of a rotary table, an X-axis displacement stage, and a Y-axis displacement stage.

[0015] Furthermore, the grinding machine tool in this application also includes a vision inspection mechanism, which is used to realize online measurement during the grinding process; the vision inspection mechanism is fixed above the workpiece table by a mounting bracket. The vision inspection mechanism mainly includes an industrial camera and its acquisition system, and the vision inspection mechanism can adopt existing technology.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The multi-wheel superhard tool grinding machine of this utility model includes a grinding mechanism and a clamping mechanism. The clamping mechanism can be used to drive the tool to perform horizontal and rotary movements, while the grinding mechanism is equipped with multiple grinding wheels. The grinding mechanism as a whole can move horizontally, and its lifting mechanism can drive some of the grinding wheels to move up and down. Through the cooperation of the grinding mechanism and the clamping mechanism, the tool can be ground at multiple angles. Since multiple grinding wheels are installed, different grinding wheels can be selected to participate in the grinding as needed, thereby achieving fine grinding or rough grinding. At the same time, it is not necessary to reload the tool to be processed, that is, it only needs to be loaded once for each processing, saving clamping time and improving processing efficiency.

Methods or functional components not specifically described in the embodiments are all prior art. Unless otherwise defined, all technical terms and scientific terms used herein have the same meaning as commonly understood by those skilled in the art. Example

[0019] like Figure 1-5As shown in the figure, this embodiment is a multi-grinding-wheel superhard tool grinding machine, which includes a machine body 1, a grinding mechanism 2 and a clamping mechanism. The machine body 1 is integrally in a "convex" shape. The clamping mechanism is arranged on one side of the head of the "convex" shape. The clamping mechanism includes a workpiece table 3 and a tool clamping seat 4. The tool clamping seat 4 is arranged on the workpiece table 3. The workpiece table 3 is used to drive the tool clamping seat 4 to move. The tool clamping seat 4 is used to clamp the tool to be processed. The grinding mechanism 2 is arranged on one side of the bottom of the "convex" shape. The grinding mechanism 2 is slidably connected to the machine body 1. The grinding mechanism 2 includes a base 21 and multiple grinding heads 23. The grinding head 23 includes a driving spindle 231 and a grinding wheel 233.

[0020] In this embodiment, a slide rail 11 is arranged on the machine body 1, and a sliding component is arranged below the base 21 of the grinding mechanism 2. Through the cooperation of the sliding component and the slide rail 11, the base 21 of the grinding mechanism 2 can move back and forth along the direction of the slide rail 11. An elevating mechanism 22 is arranged on the upper surface of the base 21, and the grinding head 23 is installed on the elevating mechanism 22. The elevating mechanism 22 adopts a cylinder or an electric cylinder.

[0021] In this embodiment, a water blocking mechanism 5 is arranged between the grinding mechanism 2 and the clamping mechanism. The water blocking mechanism 5 includes a fixed frame 51 and a water blocking plate 52. The water blocking plate 52 is slidably installed in the fixed frame 51. The water blocking plate 52 is fixedly connected to the base 21, and the base 21 can drive the water blocking plate 52 to move in the fixed frame 51. A vertical through groove is arranged on the water blocking plate 52. The end of the driving spindle 231 of the grinding head 23 installed on the elevating mechanism 22 passes through the through groove and is connected with a flange plate 232. Two annular grinding wheels 233 are arranged on the flange plate 232. The diameters of the two grinding wheels 233 are different and they are coaxially arranged. A grinding head 23 including a driving spindle 231 and a grinding wheel 233 is also fixedly installed on the water blocking plate 52. Therefore, there are three grinding wheels 233 in this embodiment. The two annular grinding wheels 233 arranged on the flange plate 232 can be used for fine grinding and rough grinding respectively. A water collecting tank 12 is arranged on one side of the head of the "convex" shape of the machine body 1. The water collecting tank 12 is used to collect the coolant flowing down due to the blockage of the water blocking plate.

[0022] In this embodiment, the workpiece table 3 successively includes a Y-axis displacement table 31, a rotary table 32 and an X-axis displacement table 33 from bottom to top, so that the workpiece table 3 can drive the tool clamping seat 4 to perform translational movements in the X\Y-axis directions and a rotational movement in the Z-axis direction.

[0023] The grinding machine in this embodiment further includes a vision detection mechanism 6. The vision detection mechanism 6 is used to realize the on-line measurement during the grinding process. The vision detection mechanism 6 is fixed above the workpiece table 3 through a mounting bracket. The vision detection mechanism 6 mainly includes an industrial camera and its acquisition system. The vision detection mechanism 6 can adopt the existing technology and will not be elaborated here.

[0024] In this embodiment, the working process of the multi-wheel 233 superhard tool grinding machine is as follows: the tool to be processed is installed on the tool holder 4, and then the corresponding grinding head 23 is started to rotate the corresponding grinding wheel 233. The position and angle of the tool to be processed are adjusted by the workpiece table 3 so that the surface of the tool to be processed comes into contact with the surface of the grinding wheel 233, thereby achieving grinding. If it is necessary to achieve rough grinding and fine grinding in steps, the workpiece table 3 can also be used in conjunction with the base 21 to adjust the horizontal position of the grinding mechanism 2, and the vertical position of the corresponding grinding head 23 can be adjusted by the lifting mechanism 22, so that the grinding wheel 233 of the grinding head 23 used for rough grinding and fine grinding respectively comes into contact with the tool at specific angle and position requirements. In summary, the grinding machine of this application only needs to load the tool once to achieve fine grinding and rough grinding, which meets various processing requirements for tools at multiple angles and positions.

[0025] The above are only some embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various combinations and modifications of the aforementioned technical features.
