Embodiment 1

[0036] Embodiment 1 is basically as follows:

[0037] General purpose mechanical camshaft shaft milling machines such as figure 1 As shown, it includes machine 1, on which slide seat 2 is slidably connected through a translation mechanism, and the lower surface of slide seat 2 is provided with a dovetail-shaped groove; the translation mechanism includes a guide rail welded on machine table 1 and matched with the groove 11. It also includes a screw rod 12 that is rotationally connected with the machine platform 1 and arranged horizontally. The right end of the screw rod 12 is connected with a translation motor 13, and the screw rod 12 is screwed with the sliding seat 2 through a threaded through hole. When the translation motor 13 starts, it drives the screw mandrel 12 to rotate, so that the slide seat 2 moves left and right.

[0038] The main motor 20 is fixed on the slide 2 by screws, and the left end of the main motor 20 is connected with a tool assembly. The tool assembly...

Embodiment 2

[0045] The difference from Embodiment 1 is that, as Image 6 As shown, the clamping seat 51 is rotatably connected with the workpiece seat 50, and the workpiece seat 50 is internally provided with a rotating motor 58. The output shaft of the rotating motor 58 is connected to the workpiece seat 50 by bolts. When the rotating motor 58 is started, the clamping seat 51 is relatively The seat 50 is rotated. When the center of the clamping seat 51 reaches the apex position along the square motion track, the rotating motor 58 can be controlled to drive the clamping seat 51 to rotate an integer multiple of 90 degrees, so that the four camshafts 8 shaft rods 80 can be exchanged, so that the square The processing difference of the surface 82 is reduced, and at the same time, under the present embodiment, the number of the milling cutters 33 is reduced, and the four camshafts 8 shaft rods 80 can still be processed into a square shape.

Embodiment 3

[0047] The difference from Embodiment 1 and Embodiment 2 is that, if Figure 7 As shown, the rotating shaft between the auxiliary gear 32 and the shaft is equally divided into two sections, and the opposite ends of the two sections of the rotating shaft are fixed with a spline shaft, and the spline shaft is slidably connected with a spline sleeve 7, and the left end of the spline sleeve 7 is connected to the seat body 3 is provided with extension spring 71, and extension spring 71 two sections are all fixed with spline cover 7 and seat body 3. The corresponding processing part 30 position below the spline sleeve 7 is provided with a push block, the push block is slidably connected with the seat body 3, the upper end of the push block is offset by a wedge-shaped surface with a slide block 73, and the slide block 73 is offset against the left end of the spline sleeve 7 and is connected to the spline sleeve 7. The seat body 3 is slidingly connected. Such as Figure 8 As shown, ...

Abstract

The invention relates to the technical field of machining equipment, in particular to a milling machine for a shaft lever of a camshaft of general machinery. The milling machine comprises a machine table and a worktable fixed to the machine table. A slide is movably connected to the machine table through a translation mechanism, a main motor is fixed to the slide, the main motor is connected to atool assembly, the tool assembly comprises a plurality of milling cutters driven by the main motor, and the milling cutters are arranged in a polygonal shape; the worktable is connected to a workpieceseat through a copying mechanism, the copying mechanism can drive the workpiece seat to move along a polygonal path, the workpiece seat is connected to a clamping seat, a plurality of clamping holesfor clamping camshafts are formed in the clamping seat, and the clamping holes as with the milling cutters are arranged in a polygonal shape. According to the scheme, the camshafts move along the polygonal path and lean against the milling cutters in the moving process to be milled, so that the camshafts can be machined at one time, and therefore, a problem of manual misoperation and high structural wear as a result of many roundtripping numbers of times of tool feeding and tool retracting in shaft lever milling in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a universal mechanical camshaft shaft milling machine. Background technique [0002] The camshaft is a part of a piston engine and is widely used in fuel vehicle engines, such as Figure 9 As mentioned above, the camshaft includes a shaft rod, one end of the shaft rod is connected with a gear plate, and a plurality of cams are connected at the middle position. At present, the camshaft is often cast in one piece, and then polished, drilled and turned to form the tooth grooves. Such as Figure 9 As shown, a square surface 82 needs to be processed on the shaft rod 80 between the gear plate 81 and the camshaft 8 to install other components. The square surface 82 is generally processed by milling. [0003] Machining the above-mentioned square surface requires workers to fix the camshaft on the clamping seat of the milling machine, control the milling cutter to...
