Description

Technical Field

[0001] The utility model relates to the field of grinding wheel trimmers, and particularly to a servo motor direct-connected grinding wheel trimmer. Background Technique

[0002] With the development of technology, it is necessary to grind some special material workpieces (such as alloy steel and bearing steel materials), so CBN grinding wheels are required for grinding. Since there is grinding wheel grinding, there must be grinding wheel trimming, so diamond rollers are used for trimming. The traditional diamond roller trimmer has a large overall volume, occupies a lot of space, and is complex to install. When grinding CBN grinding wheels, it is very easy to interfere with the workpiece. Content of the Utility Model

[0003] By providing a servo motor direct-connected grinding wheel trimmer in the embodiments of the present application, the technical problems in the existing technical solutions that the diamond roller trimmer has a large overall volume, occupies a lot of space, is complex to install, and is very easy to interfere with the workpiece when grinding CBN grinding wheels are solved.

[0004] The technical solutions adopted in the embodiments of the present application are as follows:

[0005] A servo motor direct-connected grinding wheel trimmer includes a mounting base installed on the side of the feed slide of the machine tool, a diamond roller for grinding workpieces, a grinding head seat for supporting the diamond roller, an adjustment plate for driving the grinding head seat to slide, a main shaft arranged in the inner cavity of the grinding head seat, a coupling connected to the main shaft, and a driving device installed at the rear end of the grinding head seat; a chute is opened on the mounting base, and the adjustment plate is slidably connected in the chute; the diamond roller is installed on the front end face of the main shaft; the grinding head seat is arranged on the adjustment plate; and the output shaft of the driving device is connected to the coupling.

[0006] A further technical solution is that the vertical surface of the mounting base is set as an L-shaped structure.

[0007] A further technical solution is that the grinding head seat is arranged in a split clamp type.

[0008] A further technical solution is that the driving device is a servo motor.

[0009] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0010] 1. Due to the settings of the mounting base, diamond roller, grinding head seat, adjustment plate, main shaft, coupling and drive device, the main shaft is directly connected to the drive device through the coupling, enabling extremely high rotational speeds and torques, which enhance the rigidity for dressing the CBN grinding wheel. Since the diamond roller is detachably connected to the main shaft, different-shaped diamond rollers (such as bowl-shaped, dish-shaped, cup-shaped, etc.) can be replaced according to different workpieces, thus greatly improving the practicality of the grinding wheel dresser. Due to the integral connection of the drive device and the main shaft through the grinding head seat, the installation space is saved, and the installation and disassembly are convenient, without interference with the workpiece when grinding the CBN grinding wheel.

[0014] By providing a servo motor direct-connected grinding wheel dresser in an embodiment of the present application, the technical problems in the existing technical solutions, such as the large overall volume and large floor space of the diamond roller dresser, complex installation, and easy interference with the workpiece when grinding the CBN grinding wheel, are solved.

[0015] The overall idea of the technical solution in the embodiment of the present application to solve the above problems is as follows:

[0016] To better understand the above technical solution, the above technical solution will be described in detail below in combination with the drawings in the specification and specific embodiments.

[0017] A servo motor direct-connected grinding wheel dresser, as Figure 1 shown in and as shown in Figure 2, includes a mounting base 1 installed on the side of the machine tool feed slide, a diamond roller 2 for grinding workpieces, a grinding head seat 3 for supporting the diamond roller 2, an adjustment plate 4 for driving the grinding head seat 3 to slide, a main shaft 5 disposed in the inner cavity of the grinding head seat 3, a coupling 6 connected to the main shaft 5, and a drive device 7 installed at the rear end of the grinding head seat 3. A chute 11 is provided on the mounting base 1, and the adjustment plate 4 is slidably connected in the chute 11. The diamond roller 2 is installed on the front end face of the main shaft 5. The grinding head seat 3 is disposed on the adjustment plate 4. The output shaft of the drive device 7 is connected to the coupling 6.

[0018] The grinding head seat 3 is arranged in a split clamp type.

[0019] The driving device 7 is a servo motor.

[0020] The vertical surface of the mounting base 1 is set as an L-shaped structure, which can be directly mounted on the side of the feed slide of the machine tool, saving space and being firmly mounted. A chute 11 is provided at the top of the mounting base 1, and the vertical surface of the chute 11 is a T-shaped structure. Since the adjusting plate 44 is slidably connected to the chute 11, the adjusting plate 4 can be adjusted forward and backward (large-range adjustment) through the chute 11, and thus the grinding range can be indirectly adjusted. The grinding head seat 3 presses the main shaft 5 with a single-sided locking screw. The main shaft 5 can move back and forth inside the grinding head seat 3 to finely adjust the grinding distance. The coupling 6 connects the output shaft of the main shaft 5 and the output shaft of the driving device 7. The driving device 7 is directly fixed to the rear end face of the grinding head seat 3 by connecting screws. The diamond roller 2 is directly fixed to the front end face of the main shaft 5 by connecting screws.

[0021] Due to the arrangement of the mounting base 1, diamond roller 2, grinding head seat 3, adjusting plate 4, main shaft 5, coupling 6 and driving device 7, the main shaft 5 is directly connected to the driving device 7 through the coupling 6, and ultra-high speed and torque can be obtained, which has the effect of improving the rigidity for dressing the CBN grinding wheel. Since the diamond roller 2 and the main shaft 5 are detachably connected, different-shaped diamond rollers 2 (such as bowl-shaped, disc-shaped, cup-shaped, etc.) can be replaced according to different workpieces, so the practicability of the grinding wheel dresser is greatly improved. Since the driving device 7 and the main shaft 5 are integrally connected through the grinding head seat 3, the installation space is saved, and the installation and disassembly are convenient, and there is no interference with the workpiece when grinding the CBN grinding wheel.

[0022] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications once they learn the basic creative concept. Therefore, the appended claims are intended to be construed to include the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0023] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
