Benefits of technology

[0012]Compared with the prior art, this utility model can lock and fix the guide rail by setting a locking component in the ball linear guide pair with locking function. The drive shaft of the servo motor drives the rotating shaft to rotate, which in turn drives the drive gear to rotate. The drive gear drives the driven gear to rotate through meshing connection. Since there are two sets of driven gears located on the inner walls of the mounting plate respectively, when one set of driven gears rotates, it will drive the other set of driven gears to rotate. The two sets of driven gears rotate in opposite directions, which causes one end of the driven gear to move through the limiting pull plate. The limiting pull plate drives the locking clamping block to move through the rotating rod, so that the locking clamping block rotates inward on the outer wall of the positioning rod. This causes the locking clamping block to drive the rubber elastic block to clamp the slide groove and lock it, so that the sliding steel part is locked and fixed on the outer wall of the guide rail. This solves the problem that the device cannot lock and fix in time when the linear guide pair is used, which will cause position deviation.

Description

Technical Field

[0001] This utility model relates to the technical field of ball linear guide pairs, specifically a ball linear guide pair with locking function. Background Technology

[0002] A linear guide is a mechanical assembly consisting of a guide rail, a slider, and rolling elements (such as balls or rollers) used to provide precise linear guidance, allowing objects to move smoothly and accurately in a predetermined direction. It is widely used in various precision machinery and automated equipment by reducing friction and improving the smoothness and precision of motion. However, existing linear guide pairs do not have a locking structure. When the device is used on the linear guide pair, it cannot be locked and fixed in time, which will lead to positional deviation. Furthermore, the linear guide pair has high positioning accuracy when unloaded, but it will shift when loaded.

[0003] Therefore, a ball linear guide pair with locking function is needed to improve the above problems. Utility Model Content

[0004] To address the problem that the device cannot lock and fix the ball linear guide pair in a timely manner during use, which can lead to positional deviations, this invention provides a ball linear guide pair with a locking function to solve the above-mentioned problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A ball linear guide pair with locking function includes a guide rail component, a sliding steel component slidably connected to the outer wall of the guide rail component, a locking assembly installed on the outer wall of the sliding steel component, a support assembly installed on one side of the locking assembly and on the side wall of the sliding steel component, a sliding groove formed on the opposite outer wall of the guide rail component, a rotary device installed on the opposite side wall of the sliding steel component, and an end sealing cap installed on the outer wall of the rotary device, wherein an oil nozzle is embedded in the outer wall of the end sealing cap.

[0006] As a preferred embodiment of this utility model, the locking assembly includes a mounting housing, which is mounted on the outer wall of the sliding steel component. A controller is embedded in the outer wall of the mounting housing. A mounting groove is formed on the inner wall of the mounting housing. A mounting plate is mounted on the inner wall opposite to the mounting groove. A rotating shaft is rotatably connected to the inner wall opposite to the mounting plate. A driven gear is mounted on the outer wall of the rotating shaft. Two sets of driven gears are provided and are located on the inner walls opposite to the mounting plates. The driven gears are connected by meshing.

[0007] As a preferred embodiment of this utility model, a rotating shaft is rotatably connected to one side of the driven gear and located on the inner wall of the mounting plate. A driving gear is installed on the outer wall of the rotating shaft, and a driven gear is meshed with the outer wall of the driving gear. One end of the rotating shaft passes through the mounting plate and extends to the outer wall of the mounting plate where a servo motor is installed. A limit pull plate is installed on the outer wall of the driven gear.

[0008] As a preferred embodiment of this utility model, one end of the limiting pull plate is rotatably connected to a locking clamping block via a rotating rod, a rotating rod is installed on the inner wall opposite to the mounting plate, a positioning plate is installed on the outer wall of the rotating rod, and a positioning rod is installed at one end of the positioning plate.

[0009] As a preferred embodiment of this utility model, one end of the positioning rod is rotatably connected to the outer wall of the locking clamping block, wherein the positioning rod is located directly below the rotating rod, and a rubber elastic block is embedded in the outer wall of the locking clamping block, with one end of the rubber elastic block abutting against the inner wall of the slide groove.

[0010] As a preferred embodiment of this utility model, the support assembly includes a pressure sensor and a mounting base plate. Two sets of pressure sensors are provided and are respectively located on the outer wall of the sliding steel component. The sensing end of the pressure sensor penetrates through the sliding steel component and extends into the inner cavity of the sliding steel component. The sensing end of the pressure sensor is attached to the outer wall of the guide rail component. Two sets of mounting base plates are provided and are respectively located on the opposite outer walls of the sliding steel component. A support rod is slidably connected to the outer wall of the mounting base plate.

[0011] As a preferred embodiment of this utility model, a pad is installed at one end of the support rod, and a ball bearing is rotatably connected to the inner wall of the pad. A bolt limiting pin is threadedly connected to one side of the support rod and the side wall of the mounting base plate, wherein one end of the bolt limiting pin passes through the mounting base plate and extends into the inner cavity of the mounting base plate and fits against the outer wall of the support rod. The controller is connected to a servo motor and a pressure sensor via wires, and the connection method is electrical connection.

[0012] Compared with the prior art, this utility model can lock and fix the guide rail by setting a locking component in the ball linear guide pair with locking function. The drive shaft of the servo motor drives the rotating shaft to rotate, which in turn drives the drive gear to rotate. The drive gear drives the driven gear to rotate through meshing connection. Since there are two sets of driven gears located on the inner walls of the mounting plate respectively, when one set of driven gears rotates, it will drive the other set of driven gears to rotate. The two sets of driven gears rotate in opposite directions, which causes one end of the driven gear to move through the limiting pull plate. The limiting pull plate drives the locking clamping block to move through the rotating rod, so that the locking clamping block rotates inward on the outer wall of the positioning rod. This causes the locking clamping block to drive the rubber elastic block to clamp the slide groove and lock it, so that the sliding steel part is locked and fixed on the outer wall of the guide rail. This solves the problem that the device cannot lock and fix in time when the linear guide pair is used, which will cause position deviation.

[0013] This invention provides support components within a ball-bearing linear guide pair with a locking function, enabling support for the sliding steel component and reducing its load. The load causes the sensing end of a pressure sensor to press against the outer wall of the guide component. The pressure sensor then generates an electrical signal, which is transmitted to the controller via wires. The controller displays the data for comparison with the load data. The operator then simply loosens the bolt limit pin and adjusts the position of the support rod, allowing it to move longitudinally on the outer wall of the mounting base. This movement lifts the mounting base via pads, which in turn supports the sliding steel component, reducing the load pressure between the sliding steel component and the guide component. This solves the problem of high positioning accuracy of the linear guide pair under no-load conditions, but subsequent misalignment under load. Attached Figure Description

A mounting plate 304 is mounted on the inner wall opposite to the mounting groove 303. A rotating shaft 305 is rotatably connected to the inner wall opposite to the mounting plate 304. A driven gear 306 is mounted on the outer wall of the rotating shaft 305. There are two sets of driven gears 306, which are located on the inner walls opposite to the mounting plate 304 respectively. The driven gears 306 are connected by meshing. A rotating shaft 307 is rotatably connected to one side of the driven gear 306 and located on the inner wall of the mounting plate 304. A drive gear 308 is mounted on the outer wall of the rotating shaft 307. In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A driven gear 306 is meshed on the outer wall of the drive gear 308. One end of the rotating shaft 307 passes through the mounting plate 304 and extends to the outer wall of the mounting plate 304 where a servo motor 309 is installed. A limit plate 310 is installed on the outer wall of the driven gear 306. One end of the limit plate 310 is rotatably connected to a locking clamping block 312 via a rotating rod 311. A rotating rod 313 is installed on the opposite inner wall of the mounting plate 304. A positioning plate 314 is installed on the outer wall of the rotating rod 313. A positioning rod 315 is installed on one end of the positioning plate 314. One end of the positioning rod 315 is rotatably connected to the outer wall of the locking clamping block 312. The positioning rod 315 is located directly below the rotating rod 311. A rubber elastic block 316 is embedded in the outer wall of the locking clamping block 312. One end of the rubber elastic block 316 is attached to the inner wall of the slide groove 5.

[0019] In this embodiment, specific references Figure 1 , Figure 2 and Figure 3 The support assembly 4 includes a pressure sensor 401 and a mounting base plate 402. Two sets of pressure sensors 401 are provided and are respectively located on the outer wall of the sliding steel part 2. The sensing end of the pressure sensor 401 passes through the sliding steel part 2 and extends into the inner cavity of the sliding steel part 2. The sensing end of the pressure sensor 401 is attached to the outer wall of the guide rail part 1. Two sets of mounting base plates 402 are provided and are respectively located on the opposite outer walls of the sliding steel part 2. A support rod 403 is slidably connected to the outer wall of the mounting base plate 402. A pad 404 is installed at one end of the support rod 403. A ball bearing 405 is rotatably connected to the inner wall of the pad 404. A bolt limiting pin 406 is threadedly connected to one side of the support rod 403 and the side wall of the mounting base plate 402. One end of the bolt limiting pin 406 passes through the mounting base plate 402 and extends into the inner cavity of the mounting base plate 402 and is attached to the outer wall of the support rod 403. The controller 302 is electrically connected to the servo motor 309 and the pressure sensor 401 via wires, which powers the device and causes the controller 302 to control the servo motor 309 and the pressure sensor 401 to operate.

[0020] In this solution, the ball linear guide pair with locking function operates by turning on the switch of controller 302, which in turn controls the servo motor 309 to run. When the servo motor 309 runs, its drive shaft drives the rotating shaft 307 to rotate, which in turn drives the drive gear 308 to rotate. The drive gear 308, through meshing connection, drives the driven gear 306 to rotate. Since there are two sets of driven gears 306 located on opposite inner walls of the mounting plate 304, when one set of driven gears 306 rotates, it drives the other set... The driven gear 306 rotates, and the two sets of driven gears 306 rotate in opposite directions, causing one end of the driven gear 306 to move through the limiting pull plate 310. This causes the limiting pull plate 310 to drive the locking clamping block 312 to move through the rotating rod 311, so that the locking clamping block 312 rotates inward on the outer wall of the positioning rod 315. This causes the locking clamping block 312 to drive the rubber elastic block 316 to clamp the slide groove 5 and lock it, so that the sliding steel part 2 is locked and fixed on the outer wall of the guide rail part 1. This solves the problem that the device cannot be locked and fixed in time when the linear guide rail pair is used, which will cause position deviation. When installed via the sliding steel component 2, the load applies downward pressure to the sliding steel component 2, increasing the load pressure between the sliding steel component 2 and the guide rail component 1. This causes the sensing end of the pressure sensor 401 to press against the outer wall of the guide rail component 1. Subsequently, the pressure sensor 401 generates an electrical signal, which is transmitted to the controller 302 via a wire. The controller 302 then displays the data for the operator to compare with the load data. The operator then only needs to loosen the bolt limit pin 406 and adjust the position of the support rod 403 so that the support rod 403 moves longitudinally on the outer wall of the mounting base plate 402. This causes the support rod 403 to support the mounting base plate 402 via the pad 404, which in turn supports the sliding steel component 2. This reduces the load pressure between the sliding steel component 2 and the guide rail component 1, thus solving the problem that the linear guide pair has high positioning accuracy when unloaded, but shifts under load.

Their structure, circuit, and control principle are all existing known technologies. Therefore, the structure, circuit, and control principle of the servo motor 309, pressure sensor 401, and controller 302 will not be described in detail here.
