DETAILED DESCRIPTION

[0036] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0037] like Figures 1 to 3 As shown, a cutting assembly for machining a multi-way reversing valve body comprises a cutting table 1 and a moving seat 2 arranged on the cutting table 1, wherein the cutting table 1 is provided with a first driving member 3 for driving the moving seat 2 to move linearly, and the cutting assembly for machining a multi-way reversing valve body further comprises:

[0038] The rocking seat 4 is hinged to the moving seat 2.

[0039] The support seat 5 is arranged on the rocking seat 4.

[0040] The second driving member 6 is used to drive the support seat 5 to linearly move axially along the rocking seat 4.

[0041] Two clamping members 7 are respectively arranged on the cutting table 1 and the support seat 5. The two clamping members 7 are used to clamp and fix two ends of the multi-way directional control valve body from different directions, and the two clamping members 7 are not parallel.

[0042] The limiting member 9 is arranged on the moving seat 2. The limiting member 9 is used to clamp and fix the rocking seat 4 after angle adjustment.

[0043] Before cutting the multi-way directional control valve body, first sleeved an oil port on the multi-way directional control valve body outside the clamping member 7 vertically installed on the top of the cutting table 1, and then control this clamping member 7 to expand inside the oil port on the multi-way directional control valve body and abut against the inner wall of the oil port to realize the preliminary fixation of the multi-way directional control valve body. Then control the first driving member 3 to drive the moving seat 2 close to the preliminarily fixed multi-way directional control valve body. Then, according to the orientation of another oil port on the multi-way directional control valve body, control the limiting member 9 to release the clamped rocking seat 4, and then adjust the inclination angle of the rocking seat 4 so that the rocking seat 4 is parallel to the end face of the oil port to be fixed on the multi-way directional control valve body. Then control the limiting member 9 to reverse and clamp and fix the adjusted rocking seat 4 again to prevent the rocking seat 4 from deflecting in the later operation and affecting the fixation effect of the multi-way directional control valve body. Then control the second driving member 6 to adjust the distance between the clamping member 7 on the support seat 5 and the moving seat 2 to be much larger than the height of the oil port to be fixed on the multi-way directional control valve body. Then control the first driving member 3 again to synchronously drive the moving seat 2 and all components arranged on the moving seat 2 near the multi-way directional control valve body until the axis of the clamping member 7 on the support seat 5 is parallel to the axis of the oil port to be fixed on the multi-way directional control valve body and the end of this clamping member 7 is within the range of the end face of the oil port to be fixed. Then control the second driving member 6 to reverse and drive the support seat 5 and the clamping member 7 arranged on the support seat 5 close to the multi-way directional control valve body until the clamping member 7 is inserted into the oil port to be fixed to a certain depth. Finally, control this clamping member 7 to expand inside the oil port to be fixed and abut against the inner wall of the oil port to realize the secondary fixation of the multi-way directional control valve body. The multi-way directional control valve body is fixed from two different directions by the two clamping members 7 to form a support and fixation surface, and the degrees of freedom of the multi-way directional control valve body in all directions are constrained through the mutual restraint between the multi-way directional control valve body and the two clamping members 7, so as to improve the fixation effect and stability of the multi-way directional control valve body.

[0044] The limiting member 9 includes:

[0045] Two fixing blocks 93 which are slidably connected with the limiting groove 91 arranged on the moving seat 2.

[0046] The second screw rod 92 disposed in the limiting groove 91 is rotated, and two fixing blocks 93 are relatively threadedly sleeved on the second screw rod 92 .

[0047] By controlling the second screw 92 to rotate clockwise, it drives the two fixed blocks 93 to approach each other until the two fixed blocks 93 clamp and fix the hinged ends of the rocking seat 4 and the movable seat 2, so that the rocking seat 4 can stably maintain the state after the tilt angle is adjusted, avoiding the rocking seat 4 from deflecting in the later operation and affecting the secondary fixing effect of the multi-way reversing valve body.

[0048] In this embodiment, the clamping member 7 includes:

[0049] The first screw rod 71 disposed on the support base 5 is rotated.

[0050] With respect to the two nut seats 72 threadably sleeved on the first screw rod 71 , the threads at the two ends of the first screw rod 71 are in opposite directions.

[0051] A connecting arm 73 is hinged to the nut seat 72 .

[0052] An abutment bar 74 is disposed between two adjacent connecting arms 73 .

[0053] A servo motor 75 is disposed on the support base 5 and is used to drive the first screw rod 71 to rotate.

[0054] The slider is fixed on the abutment strip 74 , and the slider is located on the end surface of the abutment strip 74 close to the support seat 5 .

[0055] Since the two ends of a resistance bar 74 are respectively hinged to the connecting arms 73 hinged on the two nut seats 72, and together with the first screw rod 71, a variable supporting surface is formed, and the two connecting arms 73 at the two ends of the resistance bar 74 are arranged in an eight-shaped or inverted eight-shaped shape, it is convenient to control the operation state of the servo motor 75 to control the resistance bar 74 to move closer to and shrink to the first screw rod 71, or to control the resistance bar 74 to remain parallel to the first screw rod and away from the first screw rod 71.

[0056] In this embodiment, the cutting assembly for machining the multi-way reversing valve body further includes a strip-shaped groove 10 provided on the cutting table 1. Opposite guiding grooves 8 are provided on the support base 5. The guiding grooves 8 are the same as the strip-shaped groove 10. The slider is slidably arranged in the guiding groove 8. With such a design, when the servo motor 75 drives the first screw rod 71 to rotate and drives the two nut seats 72 to approach or move away from each other, the circumferential degrees of freedom of the abutting strip 74 and the nut seat 72 can be restricted by the guiding groove 8 or the strip-shaped groove 10, so that the abutting strip 74 can only linearly move along the radial direction of the oil port of the multi-way reversing valve body, and thus can completely abut against the arc-shaped inner wall of the oil port. The multi-way reversing valve body is fixed from two different directions by two non-parallel clamping members 7, jointly forming a fixed support surface, enabling the two clamping members 7 to be in an interlocking state through the multi-way reversing valve body, and restricting the degrees of freedom of the multi-way reversing valve body in all directions, improving the fixing effect and fixing stability of the multi-way reversing valve body.

[0057] In this embodiment, the outer surface of one end of the swing seat 4 is an arc-shaped tooth surface. The opposite surfaces of the two fixing blocks 93 are both arc-shaped tooth surfaces, and the arc-shaped tooth surface of the fixing block 93 matches the arc-shaped tooth surface of the swing seat 4. With such a design, the friction between the two can be increased by increasing the roughness of the contact surface between the fixing block 93 and the swing seat 4, so as to cooperate with the axial extrusion force provided by the rotation of the second screw rod 92 to improve the circumferential fixing effect of the swing seat 4 and fix the swing seat 4 after the inclination angle is adjusted, avoiding affecting the accuracy and smoothness of subsequent operations.

[0058] In this embodiment, the second screw rod 92 is located below the swing seat 4, and the thread directions at both ends of the outer part of the second screw rod 92 are opposite. With such a design, by rotating the second screw rod 92, it is possible to control the two fixing blocks 93 to approach each other and clamp the swing seat 4, or control the two fixing blocks 93 to move away from each other to release the limiting and fixing effect of the fixing block 93 on the swing seat 4, so as to facilitate the user to adjust the inclination angle of the swing seat 4.

[0059] In this embodiment, the structures of the first driving member 3 and the second driving member 6 are the same. The first driving member 3 includes:

[0060] A moving block slidably connected to the sliding groove provided on the cutting table 1.

[0061] A lead screw rotatably arranged in the sliding groove. The moving block is threadedly sleeved on the lead screw.

[0062] The support base 5 is fixed on the vertical surface of one of the moving blocks, and the moving base 2 is fixed on the top of the remaining moving block. Such a design facilitates the linear control of the linear movement of the moving base 2 on the cutting table 1 and the linear movement of the support base 5 along the axial direction of the swing base 4, so as to facilitate the adjustment of the height and inclination of the support base 5 and the clamping member 7 provided thereon, enabling it to match the orientation of the oil ports on the multi-way directional control valve body, and being able to fix the multi-way directional control valve body at two points, improving the accuracy and efficiency of the fixing operation of the multi-way directional control valve body.

[0063] The above are only the preferred embodiments of the present invention, and the parts not described in the present invention can be implemented by adopting or referring to the existing technologies. Of course, the above description is not a limitation to the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present invention should also fall within the protection scope of the present invention.
