Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of grinding processing equipment, in particular to a profile grinding tool and a grinding processing equipment. BACKGROUND

[0002] Mechanical processing is the basis of the entire industrial manufacturing. In the mechanical processing field, lathe and grinding machine and other equipment are often used to process the shape of various parts. Shape processing is essential in the manufacturing of various equipment, such as machine tools, engines, automobiles, ships, mining equipment, and aviation. Cylindrical grinding is a basic means to improve the accuracy of cylindrical processing. Cylindrical grinding is a cutting process that uses high-speed rotating grinding wheels and other grinding tools to process the surface of workpieces. It can be used to process the inner and outer cylindrical surfaces, conical surfaces, and planes of various workpieces, as well as special and complex shaped surfaces such as threads, gears, and splines. It has the characteristics of high processing accuracy and small surface roughness.

[0003] Traditional cylindrical grinding equipment mainly processes cylindrical, conical, and shoulder end surfaces. If complex shaped surfaces are to be processed, complex processing programs and expensive processing equipment are required. To reduce investment and costs, profile processing equipment is generally used. Existing profile processing requires the use of special profile processing equipment. Based on a pre-made master model, the contact head is in close contact with the working surface of the master model under a certain pressure and moves along the surface, making the cutter (or grinding wheel) perform synchronous profile processing. This allows the same type of parts to be processed on the part blank. However, profile processing equipment is also expensive and requires custom-made master models, which increases the cost of part processing and is not conducive to small-batch part processing for small and medium-sized enterprises.

[0033] The following are specific embodiments of the present application and further describe the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments.

In addition, in order to be clear and concise, the description of known functions and structures is omitted.

[0034] It should be noted that the embodiments and features in the present application can be combined with each other without conflict.

[0035] At present, when processing complex forming surfaces, the price of special profile machining equipment is high, which is not conducive to small-batch part processing. Therefore, the present application provides a profile grinding tool which can process workpieces with non-circular contour surfaces by means of existing grinding machine equipment, and can replace special profile machining equipment.

[0036] Reference Figures 1-7 The profile grinding tool 100 includes a base 20, a mounting support 30, a rotating shaft 40, a driving source 50, a master 60, and a master stopper 61, and an elastic element. Among them, the base 20 is fixed on the grinding machine; the mounting support 30 is slidably mounted on the base 20; the rotating shaft 40 is rotatably mounted on the mounting support 30, and a first position 41 capable of mounting the workpiece 10 is arranged thereon; the driving source 50 is arranged on the mounting support 30 and used to drive the rotating shaft 40 to rotate; the master 60 is fixedly installed on the second position 42 of the rotating shaft 40 and synchronously rotates with the rotating shaft 40; the master stopper 61 is fixed on the base 20 and corresponds to the position of the master 60; the elastic element acts on the mounting support 30 to keep the master 60 on the rotating shaft 40 in contact with the master stopper 61, so that when the driving source 50 drives the rotating shaft 40 to rotate, the grinding tool 200 of the grinding machine can process the workpiece 10 according to the contour of the master 60.

[0037] The workpiece 10 and the profile block 60 are installed at different positions on the rotating shaft 40, and when the driving source 50 drives the rotating shaft 40 to rotate, the workpiece 10 and the profile block 60 rotate synchronously. Further, the mounting support 30 is located above the base 20, and the mounting support 30 can slide freely relative to the base 20, and due to the elastic force applied to the mounting support 30 by the elastic element, the profile block 60 on the rotating shaft 40 and the profile block stopper 61 are kept in contact. The profile block is pre-made, and the profile is consistent with the shape of the final required part. During the process of driving the rotating shaft 40 to rotate by the driving source 50, the profile block 60 and the profile block stopper 61 are kept in contact, so that the workpiece 10, the rotating shaft 40, and the mounting support 30 can be adaptively adjusted in position according to the profile of the profile block 60, and the grinding tool 200 of the grinding machine can process the workpiece 10 according to the profile of the profile block 60, and finally process the workpiece with the same profile as the profile block.

[0038] It should be understood that the profile block is pre-made, and the profile is consistent with the shape of the final required part; when a workpiece with a non-circular profile surface needs to be processed, only the profile block needs to be designed into a corresponding shape, so that the workpiece with a non-circular profile surface is processed by means of the profile block with a non-circular profile surface.

[0039] In the embodiment of the present application, the profile grinding tool 100 is applied to a grinding machine, the base 20 can be fixed on the sliding table of the grinding machine, and the grinding tool of the grinding machine can be used to process the workpiece, and the grinding tool can be a grinding wheel.

[0040] The elastic element is used to provide elastic pressing force to drive the profile block 60 to press the profile block stopper 61, so that the profile block 60 and the profile block stopper 61 are kept in contact. In an embodiment of the present application, the elastic element is a spring 71, and the spring 71 is installed in a compressed state between the mounting support 30 and the base 20. The profile grinding tool 100 further comprises a spring mounting component 72 for mounting the spring 71, and the mounting length of the spring can be adjusted.

[0041] Specifically, the elastic element is designed as a spring 71, and when the mounting support 30 is adjusted in sliding, the length of the spring 71 will be adaptively changed, and the pressing force of the profile block 60 to press the profile block stopper 61 is continuously provided. Here, the spring mounting component 72 can adjust the mounting length of the spring, and by adjusting the mounting length of the spring, the pre-tightening force of the spring can be adjusted, so that the profile block 60 can press the profile block stopper 61 with appropriate pressing force, so as to ensure the processing precision.
