Description

Technical Field

[0001] The present invention belongs to the technical field of groove milling equipment, and specifically refers to a groove milling device for machining mechanical parts. Background Technique

[0002] Milling refers to using a rotating multi-edge tool to cut the workpiece, which is a high-efficiency machining method. Milling is generally carried out on a milling machine or a boring machine, and is suitable for machining planes, grooves, various formed surfaces (such as splines, gears, and threads), and special-shaped surfaces of molds, etc. Therefore, a milling device can be used to mill the grooves of mechanical parts.

[0003] Traditional milling is mostly used for milling simple external shape features such as contours and grooves. CNC milling machines can perform machining of complex external shapes and features, and milling and boring machining centers can perform three-axis or multi-axis milling and boring machining. However, for the machining of complex curved surfaces, there are still certain limitations in the use of fixtures for milling operations. It is difficult to mill the inclined surfaces with an included angle arrangement on the workbench surface, and it is difficult to flexibly change the use. Special fixtures need to be installed, resulting in high production costs, and a large amount of time will also be wasted during the process of changing models. Summary of the Invention

[0035] During specific use, place the part to be processed on the fixture top plate 173, rotate the regulating threaded shaft 181, and then drive the fixture slide plate 18 to move, so that the fixture slide plate 18 clamps the part. Plan the milling route of the grooves to be processed on the part through the control screen on the milling cutter component 33, and start the whole device.

[0036] During the operation of the device, the motor 123 of the rod group control device 12 can control the transmission chain 125 to move on the pulley 124. The transmission chain 125 drives the guide rail slider 122 through the chain connection seat 1223. Then the guide rail slider 122 moves on the double-rod slide rail 121. When the guide rail slider 122 at the bottom of the right side plate 112 drives the first rod group 13 to move back and forth, the guide rail slider 122 at the bottom of the left side plate 111 drives the second rod group 14 to move synchronously with it, and jointly controls the bottom plate 171 of the lifting fixture rod 17 to move back and forth, thereby achieving the technical effect of controlling the fixture top plate 173 at the top of the lifting fixture rod 17 to drive the part to move back and forth. If the guide rail slider 122 at the bottom of the right side plate 112 drives the first rod group 13 to move forward, the guide rail slider 122 at the bottom of the left side plate 111 drives the second rod group 14 to move backward.

At the same time, the link - group control device 12 on the support plate 1131 is controlled by the motor 123 to move the guide - rail slider 122 on the double - rod slide rail 121. Furthermore, the guide - rail slider 122 drives link group three 15 to move left and right, and link group three 15 drives the lifting jig rod 17 to move left and right, thereby achieving the technical effect that the jig top plate 173 drives the part to move left and right; the motor 123 of the link - group control device 12 on the side of the left side plate 111 controls the guide - rail slider 122 to move on the double - rod slide rail 121, and the guide - rail slider 122 drives link group four 16 to move up and down, thereby controlling the lifting jig rod 17 to rise or fall, and achieving the technical effect that the jig top plate 173 drives the part to move up and down.

[0038] During the process that the lifting jig rod 17 moves back - and - forth and left - and - right, it drives the rotating plate 23 to move, and the rotating plate 23 drives the dust - proof slide plate 22 to slide on the surface of the processing - table body 21. The dust - proof slide plate 22 always covers the support - rod moving hole 212, preventing the metal chips generated during processing from entering the fixed frame 11 and affecting the operation of the link - group control device 12. At the same time, during the rotation of the lifting jig rod 17, the lifting jig rod 17 drives the rotating plate 23 to rotate in the rotating - plate groove 221. During the up - and - down movement of the lifting jig rod 17, the inclined - groove support rod 172 of the lifting jig rod 17 slides in the square hole 231 of the rotating plate 23.

[0039] When starting the carriage motor 32, the carriage motor 32 drives the motor screw 321 to rotate, the motor screw 321 drives the screw connection seat 311 to move, and the screw connection seat 311 drives the milling carriage 31 to slide on the carriage track 211. Furthermore, the milling carriage 31 drives the milling - cutter assembly 33 to the milling area of the part, achieving the technical effect of controlling the initial working position of the milling - cutter assembly 33 according to the size of the part to be processed.
