Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel ball assembly technology, specifically a steel ball assembly mechanism for a linear guide rail. Background Technology
[0002] In industrial automation, linear guide systems are often used to support and guide moving parts of products and mechanisms, enabling them to perform reciprocating linear motion in a given direction.
[0003] According to the publicized steel ball assembly mechanism for a linear guide rail (publication number: CN221087896U), the steel ball assembly mechanism in the above application can achieve automated pressing. The overall structure is simple. By setting a rail clamping assembly, the steel balls are confined in the steel ball groove of the cover plate, and the guide rail is pushed into the cover plate by a pushing assembly to complete the steel ball pressing. At the same time, a pressure block is set to limit the travel of the guide rail, so as to achieve precise travel positioning. The assembly efficiency is high, the operation is simple, and the stability and reliability are stable. In addition, the corresponding limit block and pressure block can be replaced according to the cover plate width and guide rail travel of the guide rail assembly to meet the requirements, which has strong versatility.
[0004] However, in actual use, although the above-mentioned equipment can perform automated pressing, the steel balls will squeeze, rub, and collide with each other during installation, which will lead to rapid wear in subsequent use. In view of this, we propose a steel ball assembly mechanism with a linear guide rail. Utility Model Content
[0005] The purpose of this invention is to provide a steel ball assembly mechanism for a linear guide rail to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel ball assembly mechanism for a linear guide rail, comprising a base, an assembly mechanism on the outer wall of the base, a chamber connected to the outer wall of the assembly mechanism, a flow valve port on the inner wall of the chamber, an application component on the outer wall of the chamber, the application component comprising a top plate fixedly connected to the outer wall of the chamber, an inclined block fixedly connected to the inner wall of the chamber, a motor fixedly connected to the outer wall of the chamber, a reciprocating threaded rod fixedly connected to the output end of the motor through the chamber, a threaded slider threadedly connected to the outer wall of the reciprocating threaded rod, a connecting rod fixedly connected to the outer wall of the threaded slider, and a mounting bracket fixedly connected to the end of the connecting rod;
[0007] A flow channel is formed on the outer wall of the mounting frame. The outer wall of the mounting frame has an insertion port. An elastic telescopic plate is fixedly connected to the inner wall of the mounting frame. An L-shaped baffle is fixedly connected to the end of the elastic telescopic plate. A flow port is formed on the outer wall of the L-shaped baffle. An oil tank is fixedly connected to the top of the mounting frame. An outlet is formed at the bottom of the oil tank. A diverter plate is fixedly connected to the bottom of the mounting frame.
[0008] Preferably, the number of inclined blocks is several, and the several inclined blocks are arranged in a linear array on the inner wall of the silo.
[0009] Preferably, the outer wall of the inclined block is adapted to the outer wall of the diverter plate, so that the diverter plate can be squeezed and touched by the inclined block after displacement.
[0010] Preferably, the centerline of the elastic telescopic plate and the centerline of the L-shaped baffle are both in the same plane.
[0011] Preferably, the outer wall of the mounting frame is provided with a scraping assembly, the scraping assembly including a crossbar, the crossbar being fixedly connected to the outer wall of the mounting frame, and a flexible scraper being fixedly connected to the end of the crossbar.
[0012] Preferably, the number of crossbars is two sets, and the two sets of crossbars are mirror images of each other on both sides of the center plane of the mounting frame.
[0013] Preferably, the outer wall of the flexible scraper is adapted to the inner wall of the chamber, so that the flexible scraper can scrape off the lubricating oil adhering to the inner wall of the chamber when it is displaced.
[0014] Compared with the prior art, this utility model provides a steel ball assembly mechanism for a linear guide rail, which has the following advantages:
[0015] 1. The ball bearing assembly mechanism of this linear guide rail can start a motor to drive the reciprocating threaded rod to rotate when assembling the ball bearings. This causes the limited threaded slider to move the connecting rod and the mounting bracket. When the mounting bracket moves, it will cause the oil tank to move synchronously. When the top plate presses against the L-shaped baffle on the elastic telescopic plate through the socket, the elastic telescopic plate will contract, causing the outlet to coincide with the flow port. This will cause the lubricating oil to flow out periodically and be dispersed onto the ball bearings below. When the mounting bracket moves, it will also drive the flow divider plate to move synchronously. After the flow divider plate moves, it can disperse the ball bearings it touches and further disperse the lubricating oil onto the ball bearings. At the same time, after the flow divider plate moves, it can be squeezed and touched by the inclined block, which will ultimately make the flow divider plate achieve a better coating effect when it swings.
[0016] 2. The steel ball assembly mechanism of this linear guide rail will simultaneously drive the crossbar and the flexible scraper to move when the mounting frame moves. This allows the flexible scraper to scrape off the lubricating oil adhering to the inner wall of the chamber, ensuring that the lubricating oil adhering to the inner wall of the chamber can further contact the steel balls, so that the steel balls can be better lubricated, and at the same time, the overall practicality is further improved.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a steel ball assembly mechanism for a linear guide rail, including a base 1, an assembly mechanism 2 on the outer wall of the base 1, a chamber 3 connected to the outer wall of the assembly mechanism 2, a flow valve port 4 on the inner wall of the chamber 3, and an application component 5 on the outer wall of the chamber 3. The application component 5 includes a top plate 501, which is fixedly connected to the outer wall of the chamber 3. An inclined block 502 is fixedly connected to the inner wall of the chamber 3. A motor 503 is fixedly connected to the outer wall of the chamber 3. A reciprocating threaded rod 504 is fixedly connected to the output end of the motor 503 through the chamber 3. A threaded slider 505 is threadedly connected to the outer wall of the reciprocating threaded rod 504. A connecting rod 506 is fixedly connected to the outer wall of the threaded slider 505. A mounting bracket 507 is fixedly connected to the end of the connecting rod 506.
[0024] Furthermore, a flow channel 508 is formed on the outer wall of the mounting frame 507, an insertion port 509 is formed on the outer wall of the mounting frame 507, an elastic telescopic plate 510 is fixedly connected to the inner wall of the mounting frame 507, an L-shaped baffle 511 is fixedly connected to the end of the elastic telescopic plate 510, a flow port 512 is formed on the outer wall of the L-shaped baffle 511, an oil tank 513 is fixedly connected to the top of the mounting frame 507, an outlet 514 is formed at the bottom of the oil tank 513, and a diverter plate 515 is fixedly connected to the bottom of the mounting frame 507.
[0025] In the embodiments of this utility model, the number of inclined blocks 502 is several, and the several inclined blocks 502 are arranged in a linear array on the inner wall of the chamber 3. The outer wall of the inclined block 502 is adapted to the outer wall of the diversion plate 515, so that the diversion plate 515 can be squeezed and touched by the inclined block 502 after displacement. The center line of the elastic telescopic plate 510 and the center line of the L-shaped baffle 511 are both in the same plane.
[0026] Furthermore, the outer wall of the mounting frame 507 is provided with a scraping component 6, which includes a crossbar 601. The crossbar 601 is fixedly connected to the outer wall of the mounting frame 507, and a flexible scraper 602 is fixedly connected to the end of the crossbar 601. There are two sets of crossbars 601, and the two sets of crossbars 601 are mirror images of the center plane of the mounting frame 507 on both sides. The outer wall of the flexible scraper 602 is adapted to the inner wall of the chamber 3, so that the flexible scraper 602 can scrape off the lubricating oil adhering to the inner wall of the chamber 3 when it is displaced.
[0027] In this invention, during daily use, the guide rail base can be pushed into the assembly mechanism 2. The assembly mechanism 2 then conveys and installs steel balls into the guide rail base. After installation, the guide rail seat is pushed out. When assembling the steel balls, the motor 503 can be started to rotate the reciprocating threaded rod 504, causing the limited threaded slider 505 to move the connecting rod 506 and the mounting bracket 507. When the mounting bracket 507 moves, it causes the oil tank 513 to move synchronously, so that the top plate 501 presses against the elastic telescopic plate 51 through the insertion port 509. When the L-shaped baffle 511 is in place, the elastic telescopic plate 510 will contract, causing the outlet 514 to coincide with the flow port 512, so that the lubricating oil will flow out periodically and be dispersed onto the steel balls below. When the mounting bracket 507 moves, it will simultaneously drive the flow divider 515 to move, so that the flow divider 515 can disperse the steel balls it touches and further disperse the lubricating oil onto the steel balls. At the same time, after the flow divider 515 moves, it can be squeezed and touched by the inclined block 502, so that the flow divider 515 can achieve a better coating effect when it swings.
[0028] When the mounting bracket 507 moves, it will simultaneously drive the crossbar 601 and the flexible scraper 602 to move. This allows the flexible scraper 602 to scrape off the lubricating oil adhering to the inner wall of the chamber 3, ensuring that the lubricating oil adhering to the inner wall of the chamber 3 can further contact the steel balls, so that the steel balls can be better lubricated, and at the same time, the overall practicality is further improved.
[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
