[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0028] Example 1

[0029] like Figures 1 to 7As shown, a pneumatic switching double-process four-axis head mechanism includes a connection conversion structure 1, a milling cutter cutting part 2, and a saw blade cutting part 3; the connection conversion structure 1 includes a four-axis head connection bracket 101, the four-axis head connection bracket 101 is installed on the cutting slide of the bridge cutting machine, and a horizontal rotary motor 102 is arranged on the four-axis head connection bracket 101, and the output shaft of the horizontal rotary motor 102 passes through the four-axis head connection bracket 101 downward in the vertical direction and is connected to the main shaft mounting bracket 103, the main shaft mounting bracket 103 includes two 7-shaped support plates and a top plate connecting the two support plates, the middle part of the top plate is fixedly connected to the output shaft of the horizontal rotary motor 102, and an asynchronous motor mounting plate 104 is rotatably installed at the bottom of the support plate through a rotating shaft, a hydraulic cylinder 105 is arranged on one side of the top plate, and the telescopic end of the hydraulic cylinder 105 is connected to the side of the asynchronous motor mounting plate 104 away from the output shaft; the saw blade cutting part 3 is installed at the bottom of the asynchronous motor mounting plate 104;

[0030] The spindle mounting bracket 103 can be driven by the horizontal rotary motor 102 to rotate 360 ​​degrees in the horizontal direction with the axis of the output shaft of the horizontal rotary motor 102 as the rotation axis, thereby changing the cutting direction of the saw blade cutting part 3 to complete straight cutting, bevel cutting, circular cutting, special-shaped cutting and other processing actions on the stone;

[0031] The asynchronous motor mounting plate 104 can be deflected with the axis of the rotating shaft as the rotating axis under the drive of the hydraulic cylinder 105, and its rotation angle is 0 to 90 degrees, thereby changing the cutting angle of the saw blade cutting part 3 and completing the chamfering cutting processing action on the stone; the hydraulic cylinder 105 is connected to the external hydraulic system through a pipeline;

[0032] A milling cutter mounting bracket 106 is disposed on the outer side of a support plate of the spindle mounting bracket 103. A pneumatic module 107 is disposed on the milling cutter mounting bracket 106 along the vertical direction. The milling cutter cutting part 2 is mounted on the slide of the pneumatic module 107.

[0033] The milling cutter mounting bracket 106 includes two L-shaped plates and a side plate connecting the two L-shaped plate vertical arms. The horizontal arm end of the L-shaped plate is fixedly connected to the support plate of the spindle mounting bracket 103, and the connection is located above the rotating shaft of the support plate and on the side of the horizontal rotating motor 102. The pneumatic module 107 is arranged on the side plate;

[0034] Since the milling cutter mounting bracket 106 is in an L-shaped plate shape, its installation on the spindle mounting bracket 103 does not affect the deflection of the asynchronous motor mounting plate 104 driven by the hydraulic cylinder 105 with the axis of the rotating shaft as the rotation axis.

[0035] The pneumatic module 107 includes a linear guide, a cylinder, and a slide. The linear guide is installed on the milling cutter mounting bracket 106, and the slide is slidably set on the linear guide. The cylinder is set on the milling cutter mounting bracket 106, and its telescopic end is connected to the slide; the cylinder is connected to the external drive system through a pipeline.

[0036] When the milling cutter cutting part 2 is working, the telescopic end of the cylinder extends to drive the slide to move linearly downward on the linear guide rail and reach the lowest point. At this time, the tip of the milling cutter is lower than the bottom of the cutting saw blade and follows the movement of the machine to achieve milling cutter cutting.

[0037] When the saw blade cutting part 3 is working, the telescopic end of the cylinder is retracted to drive the slide to move upward on the linear guide rail to reach the highest point. At this time, the tip of the milling cutter is higher than the bottom of the cutting saw blade, and the saw blade cuts following the movement of the machine.

[0038] A rotation positioning structure 4 is provided on the outer side of the rotating shaft of the support plate. When the hydraulic cylinder 105 drives the asynchronous motor mounting plate 104 to rotate, the rotation angle of the asynchronous motor mounting plate 104 can be accurately controlled, thereby performing precise chamfering of the plate.

[0039] The milling cutter cutting unit 2 comprises a variable frequency spindle motor and a milling cutter mounted on the output shaft of the variable frequency spindle motor.

[0040] The saw blade cutting part 3 comprises an asynchronous motor and a cutting saw blade mounted on the output shaft of the asynchronous motor.

[0041] Example 2

[0042] like Figure 4 As shown, as a specific structure of the rotation positioning structure 4 in Example 1, the rotation positioning structure 4 is a positioning scale block 401 arranged outside the rotating shaft of the support plate.

[0043] The positioning scale block 401 is set to two pieces, namely a 0 degree positioning block 4011 at the position where the asynchronous motor mounting plate 104 rotates at an angle of 0 and a 45 degree positioning block 4012 at the position where the asynchronous motor mounting plate 104 rotates at an angle of 45 degrees, corresponding to the saw blade cutting part 3 cutting angles of 0 degrees and 45 degrees respectively.

[0044] Example 3

[0045] As another specific structure of the rotation positioning structure 4 in Example 1, the rotation positioning structure 4 is a positioning dial arranged on the outside of the rotating shaft of the support plate, and a scale pointer used in conjunction with the positioning dial is provided on the outside of the rotating shaft of the asynchronous motor mounting plate.

[0046] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the utility model.
