[0035] The first oil supply assembly 11 includes a rotating cylinder 111, a limit baffle 112, a rotating shaft 113, a connecting conduit 114, a counterweight 115 and an oil outlet groove 116;

[0036] The second oil supply assembly 12 includes a rolling column 121 , a sleeve shaft 122 , a push plate 123 , a spring 124 and a through hole 125 .

[0037] Embodiment 1: When in use, place the mold to be processed on the clamping seat 7, start the electric clamping part installed on the side, clamp and fix the mold, keep the oil pump 133 in the distribution component 13 started, and when the x-axis part 10 drives the clamping seat 7 to move laterally, the No. 1 oil supply component 11 at the bottom of the clamping seat 7 rotates along the top surface of the inner surface of the movable seat 6. As the rotating cylinder 111 rotates, the oil outlet groove 116 rotates to be connected with the connecting groove 73. At this time, the distribution component 13 inputs the lubricating oil into the lubrication chamber 72 through the connecting conduit 114, the rotating cylinder 111, the oil outlet groove 116 and the connecting groove 73, so that the lubricating oil is coated on the No. 2 screw in the x-axis part, and the lubricating oil is filled on the sleeve rod of the x-axis part 10 through the guidance of the middle groove 74, completing the internal lubrication of the x-axis part 10; when the y-axis component 9 acts and drives the movable seat 6 and the clamped mold to move along the y-axis, the No. 1 seat 92 moves along the No. 1 screw part 91, and drives the movement of the hollow crank arm 93, so that the hollow crank arm 93 drives the movable seat 6 to move, thereby making the No. 2 oil supply component 12 rotatably installed at the bottom of the movable seat 6 move, with the rotation of the rolling column 121 in the No. 2 oil supply component 12, the raised part on the sleeve shaft 122 is driven to rotate, and the push plate 123 is intermittently pushed to move upward, with the compression of the spring 124, the push plate 123 moves upward and makes the through hole 125 connected with the middle hole 21, at this time, the lubricating oil pumped into the distribution sleeve 131 is quickly injected into the hollow crank arm 93, and the lubricating oil is conducted to the lubrication chamber 2 94, so that the lubricating oil in the lubrication chamber 2 94 is quickly coated on the screw of the No. 1 screw part 91 to complete the lubrication.

[0038] Firstly, by utilizing the distribution component 13 and the connection and coordination between the No. 1 oil supply component 11 and the No. 2 oil supply component 12, and utilizing the rotational movement of the No. 1 oil supply component 11 and the No. 2 oil supply component 12, in the process of position adjustment processing in the x-axis direction and the y-axis direction, the intermittent connection between the No. 1 oil supply component 11 and the No. 2 oil supply component 12 is synchronously realized, and the lubricating oil is actively injected into the x-axis portion 10 and the y-axis component 9 under dynamic adjustment, and the actual contact position is lubricated in a directional manner in conjunction with the directional input of the lubricating oil. In the actual processing process, the lubrication processing of the x-axis and y-axis systems under synchronous action is realized, and the actual lubrication efficiency is greatly improved. There is no need to assemble the corresponding lubrication systems on the x-axis and y-axis. In conjunction with the distribution component 13, synchronous and directional lubrication is realized, and the actual lubrication effect is good, the accuracy is high, the loss of lubricating oil is reduced, and the lubrication is lubricated on the action surface, the lubrication timeliness is high, and the lubricating oil utilization rate is high.

[0039] In addition, by coordinating the position configuration of the mounting seat 5 and the arc cover plate 14, when the adjustment processing in the x-axis direction and the y-axis direction is actually implemented, the tracks in the x-axis direction and the y-axis direction are always hidden and closed, the mounting seat 5 blocks the top of the y-axis motion track, and the arc cover plate 14 protects the No. 2 screw and the sleeve rod of the x-axis motion track, ensuring that the actual processing debris will not accumulate and adhere to the transport track, avoiding the impact on the track operation, maintaining continuous and stable mobile adjustment, and having a good use effect.

[0040] Example 2: During the mold processing process, the tool acts on the mold, generating a large amount of debris and scattering it, and the cutting fluid sprays and splashes. When the debris falls, it falls on the arc cover plate 14 and slides to the top of the mounting seat 5. As the y-axis assembly 9 drives the movable seat 6 to move back and forth along the top of the mounting seat 5, the push rod 22 at the bottom of the movable seat 6 is driven to move, so that the debris that falls on the top surface of the mounting seat 5 is pushed forward, and the debris at the rear is pushed backward into the discharge trough 16, and the debris is actively pushed out and cleaned along the front and rear ends of the mounting seat 5 to complete the cleaning process.

[0058] The working principle and use process of the present invention are as follows: when in use, the mold to be processed is placed on the clamping seat 7, the electric clamping part installed on the side is started, the mold is clamped and fixed, and the oil pump 133 in the distribution component 13 is kept started. When the x-axis part 10 drives the clamping seat 7 to move horizontally, the first oil supply component 11 at the bottom of the clamping seat 7 rotates along the top surface of the inner surface of the movable seat 6. As the rotating cylinder 111 rotates, the oil outlet groove 116 rotates to be connected with the connecting groove 73. At this time, the distribution component 13 passes the lubricating oil through the connecting conduit 114 and the rotating cylinder 111. 11. The oil outlet groove 116 and the connecting groove 73 are input into the lubrication chamber 1 72, so that the lubricating oil is coated on the No. 2 screw in the x-axis part, and the lubricating oil is filled on the sleeve rod of the x-axis part 10 through the guidance of the middle groove 74, so as to complete the internal lubrication of the x-axis part 10; when the y-axis assembly 9 is actuated and drives the movable seat 6 and the clamped mold to move along the y-axis, the No. 1 seat 92 moves along the No. 1 screw part 91 and drives the movement of the hollow crank arm 93, so that the hollow crank arm 93 drives the movable seat 6 to move, so that the bottom of the movable seat 6 The second oil supply assembly 12 rotatably installed in the second oil supply assembly 12 moves. With the rotation of the rolling column 121 in the second oil supply assembly 12, the raised portion on the sleeve shaft 122 is driven to rotate, and the push plate 123 is intermittently pushed to move upward. With the compression of the spring 124, the push plate 123 moves upward and makes the through hole 125 communicate with the middle hole 21. At this time, the lubricating oil pumped into the distribution sleeve 131 is quickly injected into the hollow crank arm 93, and the lubricating oil is communicated to the lubricating chamber 2 94, so that the lubricating oil in the lubricating chamber 2 94 is quickly coated on the screw of the first screw part 91, completing the lubrication. Slide; during the mold processing process, the tool acts on the mold, generating a large amount of debris and scattering it, and the cutting fluid sprays and splashes. When the debris falls, it falls on the arc cover plate 14 and slides to the top of the mounting seat 5. As the y-axis assembly 9 drives the movable seat 6 to move back and forth along the top of the mounting seat 5, the push rod 22 at the bottom of the movable seat 6 is driven to move, so that the debris falling on the top surface of the mounting seat 5 is pushed forward, and the debris at the rear is pushed backward into the discharge trough 16, and the debris is actively pushed out and cleaned along the front and rear ends of the mounting seat 5 to complete the cleaning process.
