Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, specifically a bidirectional sliding Star V357 guide rail. Background Technology

[0002] The Star V357 guide rail is a precision linear guide rail, commonly used in automated equipment requiring high-precision positioning and stability. It has advantages such as high positioning accuracy, low wear, suitability for high-speed motion, and ease of assembly and interchangeability. This type of guide rail is widely used in mechanical automation fields such as medical devices, 3C electronics, new energy, and national defense and military industries. It can effectively reduce the drive power required by the equipment and can withstand loads in various directions.

[0003] Chinese Patent CN209444711U discloses a bidirectional sliding guide rail mechanism, comprising a connecting seat with a hollow inner cavity; two guide rails mounted side-by-side on the upper surface of the connecting seat, extending along the length of the connecting seat; the connecting seat between the two guide rails having first and second mounting platform traction slots; a first mounting platform mounted on the two guide rails via a slider; a second mounting platform mounted on the two guide rails via a slider; a first cylinder located at the first end of the connecting seat and within the hollow inner cavity of the connecting seat; a first mounting platform connecting bracket mounted at the bottom of the first mounting platform passing through the first mounting platform traction slot and connected to the cylinder rod of the first cylinder; a second cylinder located at the second end of the connecting seat and within the hollow inner cavity of the connecting seat; a second mounting platform connecting bracket mounted at the bottom of the second mounting platform passing through the second mounting platform traction slot and connected to the cylinder rod of the second cylinder; and a positioning block located on the lower surface of the top plate of the connecting seat. This utility model can satisfy the free positioning of parts and save space.

[0004] Based on existing solutions and actual production and processing applications, the existing bidirectional sliding star V357 guide rail has unpredictable and uncompensated deviations between the actual stopping position and the theoretical command position of the slider when it slides multiple times in different directions and from different starting points. This is due to factors such as the parallelism error and elastic deformation of the guide rail itself. As a result, it cannot be used for precision machining or assembly that requires strict dimensions. Therefore, we propose a bidirectional sliding star V357 guide rail to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a bidirectional sliding Star V357 guide rail to solve the problem mentioned in the background art that when the current bidirectional sliding Star V357 guide rail moves multiple times in different directions and from different starting points, due to factors such as the parallelism error and elastic deformation of the guide rail itself, there will be an unpredictable and uncompensated deviation between the actual stopping position of the slider and the theoretical command position.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bidirectional sliding Star V357 guide rail, comprising a base:

[0007] Guide rails are fixedly installed at both the left and right ends of the top of the base, and sliders are slidably connected at both the front and rear ends of the guide rails. A connecting plate is fixedly installed on the top of the slider. A bidirectional adjustment component is provided on the frame of the base, a reinforcement component is provided on the side wall of the slider, and an installation component is provided on the frame of the base.

[0008] Preferably, the bidirectional adjustment assembly includes a guide groove, a hinge block, a ball screw, a sleeve block, and a motor. Guide grooves are provided at both the front and rear ends of the base frame, and a hinge block is slidably connected in the groove. A ball screw is rotatably connected at both the front and rear ends of the bottom of the base, and a sleeve block is threadedly connected to the body of the ball screw. A motor is fixedly installed at both the front and rear ends of the base, and the output end of the motor is connected to the body of the ball screw.

[0009] Preferably, the top of the hinge block is fixedly connected to the middle position of the bottom of the connecting plate, and the bottom of the hinge block is fixedly connected to the top of the sleeve block.

[0010] Preferably, the reinforcement component includes a support plate, a first screw, and a first fixing hole. The support plate is fixedly installed on the side wall of the slider, and the first screw is threadedly connected to the side wall at the lower end of the support plate. The first fixing holes are arrayed at both the front and rear ends of the side wall of the base, and the first fixing holes are symmetrically arranged about the vertical central axis of the base. The shank of the first screw is threadedly connected to the first fixing hole.

[0011] Preferably, the mounting assembly includes a through groove, a mounting base, a second fixing hole, a mounting plate, and a second screw. The base has through grooves at both its front and rear ends, and the through grooves are symmetrically arranged about the vertical central axis of the base. The mounting base is slidably connected to the through groove, and the second fixing holes are arranged in an array at both ends of the through groove. The mounting plate is fixedly mounted on the outer side of the upper end of the mounting base, and the second screw is threaded to both ends of the mounting plate.

[0012] Preferably, the shank of the second screw is connected to the second fixing hole by threads, and a through hole is present at the middle position of the mounting base.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: the bidirectional sliding Star V357 guide rail can actively compensate for the foundation error through the rotation of the ball screw, so as to eliminate the snake-like or jamming phenomenon during operation. At the same time, the cooperation between the first screw and the first fixing hole can prevent accidental movement caused by gravity, inertia or external load, and provide an extremely stable working platform. Then, by adjusting the mounting base, the overall parallelism, coplanarity and height equalization can be ensured to reach the best state, so as to guarantee the overall accuracy, rigidity, life and stability from the source.

[0014] 1. The motor output is connected to the ball screw body, which in turn is threaded to the sleeve block. Simultaneously, hinge blocks are fixedly connected to the bottom of the connecting plate and the top of the sleeve block. The rotation of the ball screw, through the engagement of the sleeve block, hinge block, and connecting plate, drives the slider to slide on the guide rail, allowing for precise sliding between the two sets of connecting plates. The rotation of the ball screw actively compensates for foundation errors, eliminating snake-like or jamming phenomena during operation. This results in extremely high linear motion accuracy and exceptionally smooth force during bidirectional sliding.

[0015] 2. A support plate is fixedly installed on the side wall of the slider, and a first screw is threadedly connected to the lower side wall of the support plate. At the same time, the front and rear ends of the base side wall are provided with first fixing holes in an array, so that the first screw can be screwed in and the shank of the first screw is connected to the diameter of the first fixing hole through the thread. This can strengthen the position of the connecting plate. The cooperation between the first screw and the first fixing hole can prevent accidental movement due to gravity, inertia or external load, and provide an extremely stable working platform, thereby protecting the safety of the workpiece or equipment.

[0016] 3. By pushing the mounting base to slide within the groove, it can be moved to a suitable position. Then, the second screws at both ends of the mounting plate can be screwed in. Second fixing holes are provided at both ends of the groove, allowing the screw shafts to connect with the holes via threads, thus fixing the mounting base to the base. A through hole is provided in the middle of the mounting base, allowing external bolts to be inserted and the base installed. Adjusting the mounting base ensures optimal parallelism, coplanarity, and height consistency, guaranteeing overall precision, rigidity, lifespan, and stability from the outset.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In order to solve the technical problem that when the existing bidirectional sliding Star V357 guide rail moves multiple times in different directions and from different starting points, and due to factors such as the parallelism error and elastic deformation of the guide rail itself, there will be an unpredictable and uncompensated deviation between the actual stopping position of the slider and the theoretical command position, this embodiment discloses the following technical content.

[0027] Please see Figures 1-6 The present invention provides the following technical solution:

[0028] A bidirectional sliding Star V357 guide rail includes a base 1, a guide rail 2, a slider 3, a connecting plate 4, a guide groove 5, a hinge block 6, a ball screw 8, a sleeve block 9, a motor 10, a support plate 11, a first screw 12, a first fixing hole 13, a through groove 14, a mounting base 15, a second fixing hole 16, a mounting plate 17, and a second screw.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the base 1 can be installed in a designated position according to the actual situation. The mounting base 14 can be adjusted according to the mounting holes at the designated position, allowing it to push the mounting base 14 within the through groove 13 and slide within the through groove 13. A through hole is provided in the middle of the mounting base 14, allowing external bolts to be inserted into it. Second fixing holes 15 are arrayed at both ends of the through groove 13. A mounting plate 16 is fixedly installed on the outer side of the upper end of the mounting base 14, and second screws 17 are threaded onto both ends of the mounting plate 16. When the mounting base 14 slides within the through groove 13, it... This ensures that the second screw 17 aligns with the second fixing hole 15, and also aligns the hole diameter of the mounting base 14 with the hole at the designated position. After the through hole of the mounting base 14 aligns with the hole at the designated position, the second screw 17 can be screwed in, so that the shank of the second screw 17 is connected to the second fixing hole 15 through the thread, thereby fixing the mounting base 14 and the base 1 together. After the position of the mounting base 14 is fixed, the external bolt is inserted into the through hole of the mounting base 14, and the external bolt in the through hole of the mounting base 14 can be screwed in, so that the base 1 is installed in the designated position through the external bolt. By adjusting the mounting base 14, the overall parallelism, coplanarity and height equality can be ensured to reach the best state.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, when the base 1 is installed in the designated position and precision machining or assembly is performed through the cooperation between the slider 3 and the connecting plate 4, the controller can control the operation of the two sets of motors 9 at the front and rear of the base 1 respectively. This is because the output end of the motor 9 is connected to the body of the ball screw 7. At the same time, the ball screw 7 is connected to the sleeve block 8 through the threaded transmission, and the bottom of the hinge block 6 is fixedly connected to the top of the sleeve block 8. The top of the hinge block 6 is fixedly connected to the middle position of the bottom of the connecting plate 4. When the motor 9 is running, the ball screw 7 drives the hinge block 6 to slide in the groove of the guide groove 5 through the sleeve block 8. Through the cooperation between the hinge block 6 and the connecting plate 4, the slider 3 can slide on the guide rail 2. Thus, through the separate rotation of the two sets of ball screws 7, the two sets of connecting plates 4 can be precisely adjusted. The rotation of the ball screw 7 can actively compensate for the foundation error, so as to eliminate the snake-like or jamming phenomenon during operation.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the two sets of connecting plates 4 slide separately, because the side wall of the slider 3 is fixedly installed with a support plate 10, and the lower end of the side wall of the support plate 10 is connected to the first screw 11 by a thread, and the front and rear ends of the side wall of the base 1 are provided with first fixing holes 12 in an array, and the first fixing holes 12 are symmetrically arranged about the vertical central axis of the base 1, when the connecting plate 4 is precisely slid by the ball screw 7 and the connecting plate 4 is slid to the designated position, the first screw 11 on the slider 3 can be screwed on separately, so that the rod of the first screw 11 is connected to the hole diameter of the first fixing hole 12 by a thread, thereby fixing the base 1 and the connecting plate 4 together. The cooperation between the first screw 11 and the first fixing hole 12 can prevent accidental movement due to gravity, inertia or external load, and provide an extremely stable working platform.
