[0041] Referring to Figure 1 、 Figure 6 、 Figure 7 And Figure 8As shown, a ball hinge 22 capable of connecting the base 8 is fixed in the middle of the bottom surface of the cutting chamber 1, and the base 8 can rotate along the ball hinge 22, and a telescopic cylinder 13 capable of rotating along the center of the bottom surface of the cutting chamber 1 is arranged inside and below the cutting chamber 1. When the telescopic cylinder 13 is extended or shortened, it can push the base 8 upward or pull the base 8 downward, so as to change the angle of the base 8.

When cutting is inclined, the cutting contour can be in an inclined state, which meets the requirements.

[0042] As shown in Figure 1 , Figure 6 and Figure 13 , in order to realize the rotation of the telescopic cylinder 13, a lower sliding groove 11 is arranged at the bottom of the cutting chamber 1, a large gear ring 30 is inserted into the lower sliding groove 11, the lower end surface of the telescopic cylinder 13 is fixed on the large gear ring 30, one side of the large gear ring 30 is engaged with a main gear 31, and a motor 32 capable of driving the main gear 31 to rotate is arranged inside the cutting chamber 1. The rotation of the motor 32 can drive the main gear 31 to rotate, so as to form the rotation of the large gear ring 30, so as to realize the rotation of the telescopic cylinder 13. An upper sliding groove 14 for guiding the upper end of the telescopic cylinder 13 is arranged at the position corresponding to the telescopic cylinder 13 on the lower surface of the base 8. Preferably, the upper end of the piston rod of the telescopic cylinder 13 is inserted into the inside of the upper sliding groove 14, and a thrust bearing ring capable of reducing the abrasion of the upper end of the telescopic cylinder 13 is arranged inside the upper sliding groove 14.

[0043] As shown in Figure 1 , Figure 7 and Figure 8 , four springs 10 are uniformly arranged between the lower surface of the base 8 and the bottom surface of the cutting chamber 1. The springs 10 can keep the base 8 flat, a ball hinge locking mechanism 9 capable of clamping the shaft of the ball hinge 22 is arranged inside the cutting chamber 1. The ball hinge locking mechanism 9 can clamp the shaft of the ball hinge 22, so that it is in a vertical state, so as to ensure the levelness of the base 8, and ensure the accuracy during horizontal cutting. Then, the ball hinge locking mechanism 9 is further clamped and stabilized.

[0044] Preferably, in this embodiment, the ball hinge locking mechanism 9 includes clamping plates 91 located on both sides of the shaft of the ball hinge 22, rocker arms 92 fixed on the outer sides of both ends of the clamping plates 91, gear heads 93 fixed below the gear heads 93, tooth plates 94 engaged below the gear heads 93, and opposite driving assemblies 95 for driving the two tooth plates 94 to move close to or away from each other. When the opposite driving assemblies 95 drive the two tooth plates 94 to move close to or away from each other, the opposite rotation of the two gear heads 93 can be realized, and the opening and closing of the clamping plates 91 driven by the rocker arms 92 can be realized. When the two clamping plates 91 are closed, the shaft of the ball hinge 22 can be clamped and vertical.

[0045] Continuing to refer to Figure 1 , Figure 7 and Figure 8 , the counter driving assembly 95 includes two bidirectional screw rods 953 rotatably installed on the front and back sides of the bottom surface of the cutting chamber 1, and nuts 952 symmetrically screwed on the bidirectional screw rods 953, the toothed plate 94 is installed on the upper surface of the corresponding nut 952, and the two bidirectional screw rods 953 are drivingly connected by a belt, the third motor 951 for driving one of the nuts 952 to rotate is installed inside the cutting chamber 1, and the two bidirectional screw rods 954 can be simultaneously rotated by the third motor 951 and the belt, so as to realize the relative or opposite movement of the two opposite nuts 952.

[0046] As shown in Figure 1 and Figure 3 , the diaphragm 12 is installed between the outer circumference of the base 8 and the inner wall of the cutting chamber 1, which can isolate the cooling liquid above from entering the mechanical structure below the base 8.

[0047] As shown in Figure 1 and Figure 2 , the liquid inlet pipe 3 for entering the cooling liquid is arranged on the upper side of the cutting chamber 1, and the liquid outlet pipe 2 for discharging the cooling liquid is arranged on the lower side of the cutting chamber 1, and the liquid outlet pipe 2 is located above the diaphragm 12.

[0048] Referring to Figure 1 and Figure 12 , the controller 28 and the liquid inlet mechanism 29 are further included, the hydraulic pressure detection sensor 27 is installed on one side of the inside of the liquid inlet pipe 3, and the hydraulic pressure detection sensor 27 is located above the diaphragm 12, the output end of the hydraulic pressure detection sensor 27 is electrically connected with the input end of the controller 28, and the output end of the controller 28 is electrically connected with the input end of the liquid inlet mechanism 29, so that when the hydraulic pressure detection sensor 27 detects that the hydraulic pressure is too large (reaches the bearing threshold of the diaphragm 12), the controller 28 controls the liquid inlet mechanism 29 to stop liquid inlet, so as to avoid the liquid leakage phenomenon.

[0049] As shown in Figure 1 , Figure 2 , Figure 9 and Figure 11 , the support table 15 is installed above the cutting chamber 1, the upper winding wheel 17 is rotatably installed above the support table 15, the lower winding wheel 19 is rotatably installed inside the cutting chamber 1, and the lower winding wheel 19 is located between the support frame 41 and the X-axis moving table 42, the cutting wire 20 is arranged between the upper winding wheel 17 and the lower winding wheel 19, the wire cylinder 18 is installed inside the support table 15, the cutting wire 20 goes through the wire cylinder 18, and the cutting wire 20 goes up when the upper winding wheel 17 winds, and the cutting wire 20 goes down when the lower winding wheel 19 winds, so that the reciprocating cutting wire 20 can be used for electric spark cutting.

[0050] Combination Figure 1 , Figure 9 and Figure 10 As shown, both the upper winding wheel 17 and the lower winding wheel 19 have turbines 26 fixed at their rear ends on their central shafts. A rotating shaft 24 is provided on one side of each turbine 26. Symmetrical worm gears 25 are provided at both ends of the rotating shaft 24. The worm gears 25 mesh with the corresponding turbines 26. A rotary drive structure 23 capable of driving the rotating shaft 24 to rotate is installed behind the cutting chamber 1. This allows the rotating shaft 24 to rotate, thereby driving the worm gears 25 to rotate, which in turn drives the two turbines 26 to rotate. The two turbines 26 rotate in opposite directions, so that when the upper winding wheel 17 rewinds, the lower winding wheel 19 unwinds, and vice versa.

[0051] Reference Figure 9 and Figure 10 As shown, in this embodiment, the rotary drive structure 23 includes a worm motor 231 fixed behind the cutting chamber 1, a drive wheel 232 inserted into the power output end of the worm motor 231, and a driven wheel 233 fixed in the middle of the rotating shaft 24 that can mesh with the drive wheel 232. The worm motor 231 can drive the drive wheel 232 to rotate, and then drive the rotating shaft 24 to rotate via the driven wheel 233.

[0052] The working principle of this invention is as follows: When using the benzene device, the workpiece to be cut is placed on the upper surface of the support frame 41. When the second motor 61 drives the Y-axis lead screw 62 to rotate, the Y-axis nut 63 can be displaced on the Y-axis, thereby enabling the Y-axis motion table 7 to move on the Y-axis, which in turn drives the support frame 41 to move on the Y-axis. When the X-axis lead screw 52 rotates, the X-axis nut 53 can drive the support frame 41 to move in the X direction, so that the workpiece on the support frame 41 can move on both the X and Y axes, which facilitates the cutting of the workpiece.

[0053] When tilting is required, the third motor 951 is driven, and the action of the third motor 951 and the belt can make the two double-acting lead screws 954 rotate simultaneously, so that the opposing nuts 952 on both sides can move relative to each other. Then the right gear head 93 can rotate clockwise and the left gear head 93 can rotate counterclockwise. Then the rocker arm 92 can make the clamp 91 disengage from the axis of the ball joint 22, so that the axis of the ball joint 22 can have freedom in all directions. The rotation of the motor 32 drives the main gear 31 to rotate, thereby forming the rotation of the large gear ring 30, so as to realize the rotation of the telescopic cylinder 13. After rotating it to the required position below the base 8, the telescopic cylinder 13 is driven to extend and retract to achieve the required tilt angle. At this time, the spring 10 on the lower side is in a compressed state.

[0054] After the oblique cutting is completed, leveling operation is needed, in which the telescopic air cylinder 13 is restored to the original length, the spring 10 is restored to the original length, then the third motor 951 is reversely driven to make the two sides of the rocker arm 92 drive the two sides of the clamping plate 91 to lock the shaft of the ball hinge 22, so that the ball hinge 22 has no degree of freedom, at this time the base 8 is in a horizontal state, and then horizontal cutting operation can be performed.

[0055] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can make modifications to the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
