Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a ball bearing slider. Background Technology

[0002] The application of sliders in the field of mechanical equipment is indispensable. Due to the linear motion they achieve when combined with guide rails, they play a decisive role in the machining process.

[0003] In existing technology, a slider generally includes a slider body, an end cap, and a gasket. The end cap has an integral structure, sandwiched between the end face of the gasket and the slider body. Screws pass through the gasket and end cap, and are screwed onto the slider body, pressing the gasket and end cap against one end of the slider body. A circulation channel is formed between the slider body and the end cap, and ball bearings are installed in the circulation channel. The interaction between the circulation channel and the ball bearings ensures that the slider can only move along the guide rail. However, using an integral structure for the end cap increases the manufacturing difficulty because a circulation channel needs to be created within the end cap. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art by providing a ball bearing slider, which separates the end caps and processes the channels for ball circulation on the two end caps, effectively reducing the processing difficulty and increasing production efficiency.

[0005] The technical solution of this utility model is as follows: A ball bearing slider includes a slider body and end caps and gaskets disposed at both ends of the slider body. The end caps are located between the slider body and the gaskets. The slider body has a groove that mates with a slide rail. The end caps and gaskets have slots that communicate with the groove. C-shaped grooves are formed on the two inner sidewalls of the groove. Straight holes are formed on both sides of the groove on the slider body. The straight holes are parallel to the C-shaped grooves. The end caps include a first cover plate and a second cover plate that are separately disposed. The first cover plate is disposed between the second cover plate and the slider body. The first cover plate is located on the groove. Two extension plates are provided on both sides of the opening. The two extension plates have arc-shaped grooves on their end faces facing the second cover plate. The extension plates have grooves on both sides that communicate with the arc-shaped grooves. The second cover plate has a rotary channel on its end face facing the first cover plate. The arc-shaped grooves and grooves cooperate with the rotary channel, and the grooves and rotary channel form a first opening and a second opening at their ends. The first opening corresponds to the C-shaped groove, and the second opening corresponds to the straight hole. The C-shaped groove, straight hole, and rotary channel constitute a circulation channel for the rolling ball. The groove sidewall of the second cover plate has a limiting strip extending towards the first cover plate.

[0006] The above technical solution involves splitting the end cap into two parts. The first cover plate has an arc-shaped groove and a recess, while the second cover plate has a rotary channel. After sliding in the C-shaped groove, the ball enters the rotary channel through the first opening and then enters the straight hole through the second opening. It moves in the straight hole and then moves towards the end cap located at the other end of the slider body. It then enters the rotary channel through the second opening and then enters the C-shaped groove through the first opening, thus achieving ball circulation. After the two cover plates are installed, the extension plate corresponds to the position of the rotary channel, which can prevent the ball from falling out and allow the arc-shaped groove on the extension plate to cooperate with the rotary channel to guide the ball to roll in the rotary channel. The setting of the limiting strip can limit the ball in the rotary track to prevent it from falling out when entering and exiting from the first opening, thus affecting the slider. The split design facilitates processing and effectively reduces production difficulty. During installation, the first and second cover plates can be installed first to form the end cap, and then the end cap and gasket can be installed on the slider body with screws. Both ends of the slider body are equipped with end caps and gaskets.

[0007] A further feature of this invention is that the first cover plate has a connecting hole, and the second cover plate has a connecting post, which is inserted into the connecting hole to achieve the connection between the first cover plate and the second cover plate.

[0008] With the above-mentioned further design, the structure is simple and easy to assemble and disassemble, enabling quick assembly and disassembly of the first cover plate and the second cover plate.

[0009] A further feature of this invention is that a positioning groove is provided on the extension plate below the groove, and a positioning strip is provided on the second cover plate below the rotary channel, with the positioning strip being engaged in the positioning groove.

[0010] By adopting the above-mentioned further settings, the firmness between the two cover plates is further improved, so that after the two cover plates are installed, the structure is firm and not easy to separate automatically. It is necessary for the installer to use a certain force to separate them.

[0011] A further feature of this invention is that the first cover plate has a positioning post at one end facing the slider body, and the slider body has a corresponding positioning hole. The positioning post is inserted into the positioning hole to achieve the connection between the end cover and the slider body.

[0012] The above-mentioned further design facilitates the installation and positioning of the end cap and the slider body, so that the first opening corresponds to the C-shaped groove and the second opening corresponds to the straight hole, without affecting the circulation of the ball.

[0013] A further feature of this invention is that the slider body is provided with a limiting rod that can prevent the ball from disengaging from the C-shaped groove. The limiting rod includes a rod body and L-shaped hooks at both ends of the rod body. The L-shaped hooks are perpendicular to the rod body. The second cover plate has a receiving groove on the end face away from the first cover plate for the L-shaped hooks to hook onto.

[0014] With the above-mentioned further configuration, the two L-shaped hooks can be hooked onto the receiving grooves on the end caps at both ends of the slider body, and the rod is close to the C-shaped groove. When the ball is located in the C-shaped groove, the rod can play a blocking and limiting role. The structure is simple and easy to install.

[0015] A further feature of this invention is that the gasket, the second cover plate, and the first cover plate are all provided with through holes for screws to pass through, and the slider body is provided with corresponding threaded holes. The end of the screw passes through each through hole and extends into the threaded hole, and is screwed into the threaded hole to realize the connection between the end cap, the gasket, and the slider body.

[0016] With the above-mentioned further design, the structure is simple and easy to assemble and disassemble. When the screws are screwed on, the gasket and end cap can be pressed against the end face of the slider body. After installation, the end cap and gasket are firmly connected and not easy to detach.

[0023] like Figure 1-10As shown, a ball bearing slider includes a slider body 1 and end caps 2 and gaskets 3 disposed at both ends of the slider body 1. The end caps 2 are located between the slider body 1 and the gaskets 3. The slider body 1 has a groove 11 that mates with a slide rail. The end caps 2 and the gaskets 3 have slots 21 that communicate with the groove 11. C-shaped grooves 12 are formed on the two inner sidewalls of the groove 11. Straight holes 13 are formed on both sides of the groove 11 on the slider body 1. The straight holes 13 are parallel to the C-shaped grooves 12. The end caps 2 include a first cover plate 22 and a second cover plate 23 that are separately disposed. The first cover plate 22 is disposed between the second cover plate 23 and the slider body 1. The first cover plate 22 is positioned above the second cover plate 23. Two extension plates 221 are provided on both sides of the slot 21. The end faces of the two extension plates 221 facing the second cover plate 23 have arc-shaped grooves 222. The sides of the extension plates 221 have grooves 223 communicating with the arc-shaped grooves 222. A rotary channel 231 is provided on the end face of the second cover plate 23 facing the first cover plate 22. The arc-shaped grooves 222 and grooves 223 cooperate with the rotary channel 231, and the grooves 223 and the rotary channel 231 form a first opening 232 and a second opening 233 at both ends. The first opening 232 corresponds to the C-shaped groove 12, and the second opening 233 corresponds to the straight hole 13. The C-shaped groove 12, the straight hole 13, and the rotary channel 231 constitute a power supply... The circulation channel for the rolling ball 10 is provided. The side wall of the groove 21 of the second cover plate 23 is provided with a limiting strip 234 extending towards the first cover plate 22. The end cover 2 is set in two parts. The first cover plate 22 is provided with an arc groove 222 and a groove 223. The second cover plate 23 is provided with a rotary channel 231. After the ball 10 slides in the C-shaped groove 12, it enters the rotary channel 231 from the first opening 232 and enters the straight hole 13 from the second opening 233. It moves in the straight hole 13 and moves towards the end cover 2 located at the other end of the slider body 1. It enters the rotary channel 231 from the second opening 233 and then enters the C-shaped groove 12 from the first opening 232. This design enables ball circulation. After the two cover plates are installed, the extension plate 221 corresponds to the position of the rotary channel 231, which can prevent the balls from falling out and allow the arc groove 222 on the extension plate 221 to cooperate with the rotary channel 231 to guide the balls to roll in the rotary channel 231. The setting of the limiting strip 234 can limit the balls in the rotary track to prevent them from falling out when entering and exiting from the first opening 232, which would affect the slider. The split design is convenient for processing and effectively reduces the production difficulty. During installation, the first cover plate 22 and the second cover plate 23 can be installed first to form the end cover 2. Then, the end cover 2 and the gasket 3 are installed on the slider body 1 with screws. The slider body 1 has end covers 2 and gaskets 3 installed at both ends.

[0024] The first cover plate 22 has a connecting hole 224, and the second cover plate 23 has a connecting post 235. The connecting post 235 is inserted into the connecting hole 224 to realize the connection between the first cover plate 22 and the second cover plate 23. The structure is simple and easy to assemble and disassemble, and the first cover plate 22 and the second cover plate 23 can be quickly assembled and disassembled.

[0025] The extension plate 221 has a positioning groove 225 below the groove 223, and the second cover plate 23 has a positioning strip 236 below the rotary channel 231. The positioning strip 236 is locked in the positioning groove 225, which further improves the firmness between the two cover plates. After the two cover plates are installed, the structure is firm and not easy to separate automatically. It requires the installer to use a certain force to separate them.

[0026] The first cover plate 22 has a positioning post 226 at one end facing the slider body 1. The slider body 1 has a corresponding positioning hole 14. The positioning post 226 is inserted into the positioning hole 14 to realize the connection between the end cover 2 and the slider body 1, which facilitates the installation and positioning of the end cover 2 and the slider body 1. This ensures that the first opening 232 corresponds to the C-shaped groove 12 and the second opening 233 corresponds to the straight hole 13, without affecting the circulation of the ball.

[0027] The slider body 1 is provided with a limiting rod 4 to prevent the ball from disengaging from the C-shaped groove 12. The limiting rod 4 includes a rod body 41 and L-shaped hooks 42 at both ends of the rod body 41. The L-shaped hooks 42 are perpendicular to the rod body 41. The second cover plate 23 has a receiving groove 237 on the end face away from the first cover plate 22 for the L-shaped hooks 42 to hook onto. The two L-shaped hooks 42 can be hooked onto the receiving grooves 237 on the end caps 2 at both ends of the slider body 1, respectively. The rod is close to the C-shaped groove 12. When the ball is located in the C-shaped groove 12, the rod can play a blocking and limiting role. The structure is simple and easy to install.
