Description

Technical Field

[0001] The present invention relates to the technical field of CNC machine tool module slides, in particular to a high-speed linear ball screw module slide for CNC machine tools. Background Art

[0002] A high-speed linear ball screw module slide is an automated device consisting of a ball screw, linear guides, and servo motors. It is primarily used to convert rotary motion into linear motion. The operating principle is that a servo motor drives a coupling to rotate the ball screw. This, combined with the ball bearing at the bottom of the linear module, allows the screw to complete the rotation process while remaining stationary, thereby converting rotary motion into linear reciprocating motion. High-speed linear ball screw module slides are widely used on CNC machine tools.

[0003] Patent number CN215257667U discloses a single-line rail ball screw guide linear slide module, comprising a base, a support plate symmetrically fixedly connected to the upper end of the base, a ball screw connected to the support plate via two bearings for joint rotation, a T-shaped sliding seat mounted on the ball screw, a motor mounted on one of the side walls of the support plate, the output end of the motor connected to one end of the ball screw via a coupling, two sliding holes defined in the sliding seat on either side of the ball screw, two sliding rods fixedly connected to the opposing side walls of the two support plates, and the sliding seat slidably connected to the corresponding sliding rods via the sliding holes. This utility model can automatically lubricate the ball screw when the sliding seat moves, reducing friction between the ball screw and the sliding seat and increasing the service life of the sliding seat and the ball screw.

[0004] However, the above-mentioned single-line ball screw guide linear slide module still has the following shortcomings:

[0005] Although the above device can automatically lubricate the ball screw, excessive lubricating oil on the surface of the ball screw is easy to overflow onto the surface of the sliding seat during the pushing process of the sliding seat, increasing the difficulty of subsequent cleaning. At the same time, excess lubricating oil drips into the open collection tank. When the lubricating oil is not excessive and cannot flow into the oil collection tank, the lubricating oil in the open collection tank is easily affected by the external environment and fouling is easily accumulated, affecting the quality and making it difficult to reuse. For this reason, we propose a high-speed linear ball screw module slide for CNC machine tools. Summary of the Invention

[0006] The purpose of the present invention is to provide a high-speed linear ball screw module slide for CNC machine tools, so as to solve the problem that although the above-mentioned device proposed in the above-mentioned background technology can automatically apply lubricating oil to the ball screw, excessive lubricating oil on the surface of the ball screw is easy to overflow to the surface of the sliding seat during the pushing process of the sliding seat, increasing the difficulty of subsequent cleaning. At the same time, excess lubricating oil drips into the open collection tank. When the lubricating oil is not excessive and cannot flow into the oil collection tank, the lubricating oil in the open collection tank is easily affected by the external environment and is easily fouled, affecting the quality and difficult to reuse.

[0008] The auxiliary component includes a bracket, which is arranged below the oiling mechanism. A group of arc-shaped baffles are symmetrically fixed to the front and rear ends of the bracket, and a group of extension plates are symmetrically fixed to both sides of the bracket. A guide groove is provided on the inner side of the top of the extension plate, and a card slot is provided on the surface of the extension plate away from the bracket. A threaded pipe is screwed to the inner side of the bottom of the bracket, and the bottom end of the threaded pipe is fixed to the oil collecting tank.

[0009] Preferably, the arc-shaped baffle and the extension plate are respectively formed integrally with the bracket, and the oil collecting tank forms a detachable structure with the bracket via a threaded tube, and the threaded tube is communicated with the oil collecting tank.

[0010] Preferably, the driving assembly includes a motor seat, which is arranged on the surface of the base, a ball screw body is engaged on the inner side of the motor seat, one end of the ball screw body is connected to a servo motor, a nut seat is provided on the surface of the ball screw body, a connecting frame is provided on the outside of the nut seat, a slide body is provided on the top of the connecting frame, auxiliary slides are provided at the four corners of the bottom of the slide body, the slide body and the auxiliary slide are connected by a number of bolts, and a linear guide rail is engaged on the inner side of the bottom of the auxiliary slide.

[0011] Preferably, the nut seat and the connecting frame are threadedly connected, and the connecting frame and the slide body are fixedly connected.

[0012] Preferably, the slide body forms a sliding structure through an auxiliary slide and a linear guide rail, and the linear guide rail is threadedly connected to the base.

[0013] Preferably, the oiling mechanism includes an oil tank, which is fixedly connected to the bottom of the slide body, an oil nozzle is provided at the front end of the oil tank, a conduit is provided at the bottom of the oil tank, a hollow arc frame is provided on the outer side of the bottom of the conduit, a number of brush clusters are distributed on the inner side of the hollow arc frame, a group of clamping frames are symmetrically fixed on both sides of the hollow arc frame, a group of guide rods are fixed horizontally to the bottom of the clamping frame, a group of U-shaped frames are symmetrically clamped on the sides of a group of clamping frames, a T-shaped limit rod is passed through the middle end of the U-shaped frame, and a spring is sleeved on the surface of the T-shaped limit rod.

[0014] Preferably, the conduit is communicated with the hollow arc frame, and an electronic valve is provided inside the conduit.

[0015] Preferably, a plurality of guide holes are opened on the inner wall of the hollow arc frame, and the guide holes are evenly distributed among the plurality of brush clusters.

[0016] Preferably, the bracket forms a locking structure through a guide rod and a guide groove, and the U-shaped bracket passes through the side of the bracket and is locked in the inside of the locking groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention effectively intercepts and collects excess dripping lubricating oil through the cooperation of the bracket and the arc-shaped baffle, thereby preventing the lubricating oil from dripping onto the surface of the base. Since the bracket is arc-shaped, the excess dripping lubricating oil will eventually flow to the bottom inside the bracket and flow into the oil collecting tank through the threaded pipe, which is convenient for reuse. The oil collecting tank can be subsequently screwed to separate the threaded pipe from the bracket, and the oil collecting tank can be disassembled.

[0019] 2. The servo motor in the present invention can effectively drive the ball screw body to rotate, thereby driving the nut seat on the surface of the ball screw body to perform linear motion. Since the nut seat is connected to the connecting frame, it can effectively drive the slide body to perform linear motion. The cooperation between the auxiliary slide and the linear guide rail can increase the movement stability of the slide body, and at the same time share the load-bearing surface of the slide body, avoiding the concentration of all gravity on the ball screw body.

[0020] 3. In the present invention, when it is necessary to oil the ball screw body, the electronic valve inside the conduit is opened, so that the lubricating oil in the oil tank enters the hollow arc frame through the conduit, and then the lubricating oil flows out through a number of guide holes opened on the inner wall of the hollow arc frame and adheres to the surfaces of a number of brush clusters. When the slide body performs linear motion, the number of brush clusters effectively sweeps the surface of the ball screw body, thereby realizing automatic oiling. When it is necessary to clean the bracket, the U-shaped bracket is pulled outward to disengage its end from the slot, thereby realizing rapid disassembly of the bracket. Similarly, when installing the bracket, the guide rod is clamped into the guide groove on the basis of pulling the U-shaped bracket outward, and then the U-shaped bracket is released. Under the influence of the spring rebound force, the end of the U-shaped bracket is clamped into the slot, thereby realizing rapid assembly between the oiling mechanism and the auxiliary components.

The present invention effectively intercepts and collects excess dripping lubricating oil through the cooperation of the bracket 401 and the arc-shaped baffle 402, thereby preventing the lubricating oil from dripping onto the surface of the base 1. Since the bracket 401 is arc-shaped, the excess dripping lubricating oil will eventually flow to the inner bottom of the bracket 401 and flow into the oil collecting tank 407 through the threaded tube 406, which is convenient for reuse. The oil collecting tank 407 is subsequently screwed to separate the threaded tube 406 from the bracket 401, and the oil collecting tank 407 can be disassembled.

Auxiliary slides 207 are provided at the four corners of the bottom of the slide body 206. The slide body 206 and the auxiliary slide 207 are connected by several bolts 208. A linear guide 209 is engaged with the inner side of the bottom of the auxiliary slide 207. Furthermore, the slide body 206 forms a sliding structure with the linear guide 209 through the auxiliary slide 207, and the linear guide 209 is threadedly connected to the base 1. The servo motor 203 in the present invention can effectively drive the ball screw body 202 to rotate, thereby driving the nut seat 204 on the surface of the ball screw body 202 to perform linear motion. Since the nut seat 204 is connected to the connecting frame 205, it can effectively drive the slide body 206 to perform linear motion. The cooperation between the auxiliary slide 207 and the linear guide rail 209 can increase the movement stability of the slide body 206, and at the same time share the load-bearing surface of the slide body 206, avoiding that all gravity is concentrated on the ball screw body 202.

[0035] The oiling mechanism 3 includes an oil tank 301, which is fixed to the bottom of the slide body 206. An oil nozzle 302 is provided at the front end of the oil tank 301, a conduit 303 is provided at the bottom of the oil tank 301, and a hollow arc frame 304 is provided on the outside of the bottom of the conduit 303. The conduit 303 is connected to the hollow arc frame 304, and an electronic valve is provided inside the conduit 303. A number of brush clusters 305 are distributed inside the hollow arc frame 304. Further, a number of diversion holes are opened on the inner wall of the hollow arc frame 304, and the diversion holes are evenly distributed on the brushes. Between the clusters 305, a group of brackets 306 are symmetrically fixed on both sides of the hollow arc frame 304, and a group of guide rods 307 are fixed horizontally to the bottom of the brackets 306. A group of U-shaped brackets 308 are symmetrically connected to the sides of a group of brackets 306. Furthermore, the brackets 306 form a locking structure with the guide groove 404 through the guide rods 307. The U-shaped bracket 308 passes through the side of the bracket 306 and is locked in the inside of the slot 405. A T-shaped limit rod 309 runs through the middle end of the U-shaped bracket 308, and a spring 310 is sleeved on the surface of the T-shaped limit rod 309. In the present invention, when the ball screw body 202 needs to be oiled, the electronic valve inside the conduit 303 is opened, so that the lubricating oil in the oil tank 301 enters the hollow arc frame 304 through the conduit 303, and then the lubricating oil flows out through the several guide holes opened on the inner wall of the hollow arc frame 304 and adheres to the surface of the several brush clusters 305. When the slide body 206 performs linear motion, the several brush clusters 305 effectively sweep the surface of the ball screw body 202, thereby realizing automatic When cleaning the bracket 401 after oiling, pull the U-shaped frame 308 outward to disengage its end from the slot 405, thereby enabling quick disassembly of the bracket 401. Similarly, when installing the bracket 401, insert the guide rod 307 into the guide groove 404 on the basis of pulling the U-shaped frame 308 outward, and then release the U-shaped frame 308.

[0036] Working principle: The device is installed as a whole at the required position of the CNC machine tool through the base 1, and the parts required for linear motion are fixed on the surface of the slide body 206. The servo motor 203 drives the ball screw body 202 to rotate, thereby driving the nut seat 204 on the surface of the ball screw body 202 to perform linear motion. Since the nut seat 204 is connected to the connecting frame 205, it can drive the slide body 206 to perform linear motion. The cooperation between the auxiliary slide 207 and the linear guide 209 can increase the slide body 206 can be moved stably, and the load-bearing of the surface of the slide body 206 can be shared, so as to avoid that all the gravity is concentrated on the ball screw body 202. When the ball screw body 202 needs to be oiled, the electronic valve inside the conduit 303 is opened, so that the lubricating oil in the oil tank 301 enters the hollow arc frame 304 through the conduit 303, and then the lubricating oil flows out through the several guide holes opened on the inner wall of the hollow arc frame 304 and adheres to the surface of the several brush clusters 305. When the slide body 206 performs linear motion, several The brush cluster 305 sweeps the surface of the ball screw body 202 to achieve automatic oiling. The bracket 401 and the arc baffle 402 cooperate to intercept and collect excess dripping lubricating oil to prevent the lubricating oil from dripping onto the surface of the base 1. Since the bracket 401 is arc-shaped, the excess dripping lubricating oil will eventually flow to the bottom of the inner side of the bracket 401 and flow into the oil collecting tank 407 through the threaded tube 406 for easy reuse. The oil collecting tank 407 is subsequently screwed to separate the threaded tube 406 from the bracket 401. The oil collecting tank 407 can be disassembled. When the bracket 401 needs to be cleaned, the U-shaped frame 308 is pulled outward to disengage its end from the slot 405, thereby realizing the rapid disassembly of the bracket 401. Similarly, when installing the bracket 401, the guide rod 307 is inserted into the guide groove 404 on the basis of pulling the U-shaped frame 308 outward, and then the U-shaped frame 308 is released. Under the influence of the rebound force of the spring 310, the end of the U-shaped frame 308 is inserted into the slot 405, thereby realizing the rapid assembly between the oiling mechanism 3 and the auxiliary component 4.
