Description

Improved structure of processing head of multi-axis processing machine

The invention relates to the technical field of the structure of the processing head of a multi-axis processing machine, especially an improvement of the processing head of a multi-axis processing machine with the functions of reducing loss, prolonging the service life and processing precision, and having energy saving effects. Structurer.

Generally, the structure of the processing head of the conventional multi-axis processing machine, as shown in Figures 1 to 3, is mainly combined with an adapter 11 that can rotate coaxially with a first central axis A under an input shaft head 10. One side of the adapter 11 is combined with an output shaft head 12 that can rotate and move coaxially with a second central axis B. Wherein the first central axis A is perpendicular to the second central axis B.

In Figure 2, it is pointed out that when the output shaft head 12 is to be rotated by an angle according to processing requirements, it is necessary to use the oil circuit in the adapter 11 to drive the output shaft head 12 completely by means of hydraulic pressure. Axially move outward, and then make one of the first positioning toothed plates 120 fixed on one side of the output shaft head 12 break away from the second positioning toothed plate 110 fixed on one side of the adapter 11, so that the output shaft can be formed to allow The head 12 can rotate coaxially on one side of the adapter 11, and while the output shaft head 12 is axially moving outward, the clutch ring gear 121 fixed on one side of the output shaft head 12 will be in contact with the fixed output shaft head 12. on the adapter 11, a clutch gear 113 on the second bevel gear shaft 112 of the second bevel gear 111 is engaged, so that one of the input shaft 100 in the input shaft head 10 can drive the first bevel gear 114 of the adapter 11 Rotate, then the second bevel gear 111 meshed with it rotates, and therefore the clutch gear 113 fixed on the second bevel gear shaft 112 rotates accordingly, and then drives the clutch ring gear 121 meshed with it to rotate, And therefore, the output shaft head 12 can be linked to rotate to the required processing angle.

It is pointed out in Fig. 3 that after the output shaft head 12 is rotated to the required processing angle, the oil path in the adapter 11 can be used to drive the output shaft head 12 in the entire direction by means of hydraulic drive. Inner axial movement, and then make the first positioning toothed plate 120 and the second positioning toothed plate 110 mesh, to form a positioning state that does not allow the output shaft head 12 to rotate coaxially on the side of the adapter 11, and the output While the shaft head 12 is axially moving inward, the clutch ring gear 121 will disengage from the clutch gear 113, so that the input shaft 100 can drive the first bevel gear 114 to rotate, and then drive the second bevel gear 111 to rotate, And make the second bevel gear shaft 112 drive one of the third bevel gear 122 in the output shaft head 12 to rotate, and then drive the fourth bevel gear 123 meshed with the third bevel gear 122 to rotate, and thus drive the third bevel gear 123 that is meshed with the third bevel gear 122 to rotate. An output shaft 124 fixed to the four bevel gears 123 rotates, so that a tool (not shown) mounted on the output shaft 124 can cut the workpiece.

However, before and after the output shaft head 12 rotates an angle, it is necessary to make the output shaft head 12 move outward and inward axially relative to the adapter 11 to generate the clutch state, and because the output shaft head 12 The system has considerable weight, so when the adapter 11 axially moves out a certain distance, it will form a cantilever state, and it and The connecting part of the adapter 11 needs to bear a very large pressure, so it will cause a very large loss and greatly shorten its service life. Affect its processing precision. Moreover, using oil pressure to drive the heavy output shaft head 12 to move is more energy-consuming.

In view of this, the present inventors aimed at the above-mentioned problems, conceived deeply, and actively researched and improved the trial production to develop and design the present invention.

The main purpose of the present invention is to solve many problems such as easy loss and energy consumption in the structure of the processing head of the conventional multi-axis processing machine.

The improved structure of the processing head of the multi-axis processing machine according to the present invention includes an input shaft head, an adapter and an output shaft head. Wherein, the input shaft head is provided with an input shaft that can rotate coaxially. The adapter is rotatably combined under the input shaft head, and inside is provided with a first bevel gear that can be rotated by the input shaft and a second bevel gear that meshes with the first bevel gear. One side of the adapter is provided with a first positioning toothed plate and a clutch wheel. The first positioning toothed plate can be hydraulically driven to move its axial displacement. The clutch wheel system is rotatably combined in the adapter and Has multiple locating slots. The output shaft head is rotatably combined with one side of the adapter, and there is a rotatable third bevel gear inside, and the third bevel gear has a third bevel gear shaft extending to the adapter It is keyed with the second bevel gear and the clutch wheel so that the third bevel gear, the second bevel gear and the clutch wheel can rotate synchronously. One side of the output shaft head is provided with a The toothed plate engages or separates a second positioning toothed plate and a plurality of inserts that can be elastically displaced laterally, and makes the plurality of inserts elastically abut against the first One side of the positioning toothed disc can be axially displaced along with the first positioning toothed disc. When the first positioning toothed disc is displaced to separate from the second positioning toothed disc, the plurality of inserts are inserted into the plurality of positioning slots Among them, when the first positioning toothed plate is displaced to mesh with the second positioning toothed plate, the plurality of inserts are disengaged from the plurality of positioning slots, and a rotatable output shaft is provided in the output shaft head, and the output A fourth bevel gear that can rotate synchronously is arranged on the shaft, and the fourth bevel gear train meshes with the third bevel gear.

The improved structure of the processing head of the multi-axis processing machine provided by the present invention can be designed by the above-mentioned special structure, so that the output shaft head will not move axially before and after turning an angle, so the conventional cantilever can be avoided. Therefore, it has the effect of reducing loss and greatly prolonging the service life and processing precision. Moreover, the clutch mechanism for controlling the rotation of the output shaft head only needs to use oil pressure to drive the relatively light first positioning chainring to move in the axial direction, so it can reduce energy consumption and have energy-saving effect.

The output shaft head 40 is combined with one side of the adapter 30 and can rotate around the second central axis T. As shown in FIG. Corresponding to the second central axis T, the output shaft head 40 is provided with a third bevel gear 41 that can rotate coaxially. The third bevel gear 41 has a third bevel gear shaft 410 extending into the adapter 30 and The second bevel gear 32 and the clutch wheel 34 are keyed together so that the third bevel gear 41 , the second bevel gear 32 and the clutch wheel 34 can rotate synchronously. One side of the output shaft head 40 is provided with a second positioning toothed disc 42 that can be engaged or separated from the first positioning toothed disc 33, and the second positioning toothed disc 42 is composed of an annular inner toothed disc 420 and An external toothed disc 421 is formed.
