Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and in particular relates to a groove milling device. Background Art

[0002] Shaft parts are commonly used mechanical parts in China's current industrial products, such as mechanical transmission, guides, etc. Some shaft parts generally have side grooves processed on the side to meet actual functional requirements. At present, shaft parts are generally processed by lathes, then slotted by milling machines or machining centers, or directly processed by turning and milling composite equipment.

[0003] For the machining of shaft parts by the milling-turning compound equipment, the parts are first turned by the turning part of the milling-turning compound, and then the side of the parts is milled by the cutting tool. If multiple faces need to be machined, the spindle of the lathe needs to be rotated to achieve machining at different positions. For example, the Chinese patent document with publication number CN218946910U discloses a double-station milling-turning compound lathe, including a frame, a first spindle is fixedly installed on the left end of the upper side of the frame, a first guide rail is fixedly installed on the upper side of the frame, a slide is slidably installed on the first guide rail, a second spindle is fixedly installed on the slide, the second spindle is arranged on the right side of the first spindle, and the second spindle and the first spindle are on the same axis, a second guide rail is fixedly installed on the upper side of the frame, two turrets are slidably installed on the second guide rail, and the two turrets are arranged symmetrically with each other, a tool changing motor is fixedly installed on the side of the turret, and a tool changing disc is fixedly installed at the rotor of the tool changing motor, and the tool changing disc is arranged behind the axis of the first spindle and the second spindle. It can realize double-station turning and milling compound processing.

[0004] In the technical solution of the above patent document, when the workpiece is milled, one end of the workpiece is clamped, but the other end is in a suspended state. Therefore, the workpiece will be deformed by force during the milling process, especially slender shafts, which are more susceptible to deformation by force. Even if the two ends of the part are clamped and fixed, when the cutting tool processes the middle position of the part, the part will still be deformed by force in the middle. Utility Model Content

[0030] In one embodiment of the slot milling device of the utility model, please refer to Figure 1 to Figure 4 The slot milling device is used for side slot milling of shaft parts. It includes a machine base 100, a support base 200, a lifting mechanism 300, a clamping mechanism 400, and a slot milling mechanism 500. The support base 200 is vertically arranged on the machine base 100; the lifting mechanism 300 is arranged on the support base 200, and the clamping mechanism 400 is arranged at the lifting end of the lifting mechanism 300. The clamping mechanism 400 is used to clamp the upper end of the shaft and make the lower end of the shaft face the working panel 110 of the machine base; the clamping mechanism 400 has a clamping center 410.

[0031] A plurality of groups of slot milling mechanisms 500 are distributed around the clamping center 410 on the machine base 100, and the slot milling mechanisms 500 include a translation mechanism 510, a driving device 520, and a cutting blade 530; the translation mechanism 510 is arranged on the machine base 100, the driving device 520 is connected to the translation mechanism 510, and the cutting blade 530 is arranged on the driving device 520; the translation mechanism 510 is used to drive the cutting blade 530 to approach or move away from the clamping center 410. Specifically, because the clamping mechanism 400 clamps the upper end of the shaft, and the lower end of the shaft faces the machine base working panel 110, when the lifting mechanism 300 drives the clamping center 400 to move up and down, the shaft will not be laterally offset during the movement. The clamping center 400 clamps the shaft and moves downward, gradually extending toward the cutting tool 530 of the slot milling mechanism. Each cutting tool 530 can cut the side of the shaft at the same time. During the processing, each cutting tool 530 positions and supports the other end of the shaft, and the cutting tool 530 always supports and positions the cutting position of the shaft, thereby avoiding the problem of deformation of the shaft due to cutting force during the cutting process. Since multiple sets of slot milling mechanisms 500 are provided, multiple side grooves can be cut at the same time at one time, thereby improving processing efficiency. The slot milling mechanism is provided with a translation mechanism 510, which can drive the cutting tool 530 to approach or move away from the clamping center 410, thereby adjusting the cutting depth, or adjusting the cutting position according to the different diameters of the shaft, to meet the side slot milling requirements of shafts of different diameters. In addition, the shaft being processed is vertically downward during processing, thereby avoiding the problem of bending and deformation due to the influence of its own gravity.

[0032] Furthermore, the working panel 110 of the machine base is also provided with a clearance hole 120 located at the bottom side of the clamping mechanism 400 , and the clearance hole 120 is used to avoid the shaft.

[0033] Furthermore, the working panel 110 is provided with an upwardly protruding boss 130, and the avoidance hole 120 is provided on the boss 130; the milling groove mechanism 500 is provided around the boss 130. Specifically, the avoidance position 120 is provided on the boss 130, and the milling groove mechanism 500 is provided around the boss 130, and the debris generated by the cutting tool 530 when cutting the processing shaft can directly fall into the avoidance hole 120 of the boss, which is convenient for unified cleaning.

[0034] Further, the boss 130 is in a triangular structure, and the number of the milling groove mechanism 500 is three groups, and they are respectively arranged on three sides of the boss 130. Specifically, the boss 130 is in a triangular structure, which facilitates the positioning and installation of the milling groove mechanism 500.

[0035] Further, the driving device 520 includes a mounting seat 521, a spindle seat 522, a cutting spindle 523 and a driving member 524.

Specifically, the mounting seat 521 is arranged on the translation mechanism 510, so that the spindle seat 522, the cutting spindle 523 and the driving member 524 can be kept stable on a horizontal plane.

[0036] Furthermore, the lifting mechanism 300 includes a fixed plate 310, and the clamping mechanism 400 is slidably disposed on one side of the fixed plate 310; a guide plate 320 is also disposed on the bottom side of the fixed plate 310, and the guide plate 320 is provided with a guide hole 321, and the guide hole 321 is coaxially arranged with the clamping center 410 of the clamping mechanism. Specifically, the clamping mechanism 400 is slidably disposed on one side of the fixed plate 310, and the fixed plate 310 can further improve the stability of the clamping mechanism 400 sliding up and down. Because the guide hole 321 of the guide plate is coaxially arranged with the clamping center 410 of the clamping mechanism, when the shaft moves downward, the guide hole 321 can position the shaft, further avoiding problems such as tilting or deformation of the shaft during clamping or processing of the clamping mechanism.

[0037] Furthermore, the clamping mechanism 400 includes a cartridge seat 420 and an elastic jacket 430; the cartridge seat 420 is connected to the lifting mechanism 300, a tapered hole is provided in the cartridge seat 420, the elastic jacket 430 is provided in the tapered hole, a pull rod is provided in the cartridge seat 420, and the pull rod is connected to the hydraulic cylinder. The upper end of the shaft part can be extended into the elastic jacket 430, and the pull rod is driven by the hydraulic cylinder, so that the elastic jacket 430 cooperates with the tapered hole in the cartridge seat 420, thereby clamping the upper end of the shaft part.
