Description

Technical Field

[0001] The utility model relates to the technical field of linear modules, in particular to a linear module with high precision and anti-wear property. Background Technique

[0002] The linear module has several names, such as linear module, Cartesian robot, linear slide, etc. It is an automated upgrade unit following linear guide rails, linear motion modules, and ball screw linear drive mechanisms. It can achieve linear and curvilinear motion of the load through the combination of each unit, making the automation of light loads more flexible and positioning more accurate.

[0003] Currently, when the slider speed of the linear module is too fast, it is easy to collide with the driving device or end cover at the end of the lead screw. Such impacts may cause damage to the equipment and wear to the slider, thus shortening the service life of the linear module.

[0004] Therefore, we propose a linear module with high precision and anti-wear property. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a linear module with high precision and anti-wear property.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A linear module with high precision and anti-wear property includes a main frame. Anti-collision rubber pads are arranged on both corresponding sides of the main frame. A guide block is slidably installed at the bottom of the main frame. A slider is fixedly installed on the upper surface of the guide block. The slider is slidably connected with a guide rod, and the slider is in threaded engagement with a threaded rod.

[0008] As a further scheme of the utility model: Both ends of the guide rod are fixedly connected with the main frame. A driving device is fixedly installed at one end of the main frame, and the output end of the driving device is fixedly connected with the threaded rod.

[0009] As a further scheme of the utility model: The threaded rod is rotatably connected with the main frame. A guide rail is fixedly installed on the bottom surface of the main frame, and the guide rail is slidably connected with the guide block.

[0010] As a further scheme of the utility model: A number of bottom plates are fixedly installed on both corresponding sides of the main frame. Every four bottom plates form a group. A rotating rod is fixedly installed on the bottom plate, and a first connecting rod and a second connecting rod are rotatably installed on the rotating rod.

[0011] As a further scheme of the utility model: The first connecting rod is rotatably connected with the second connecting rod. Shock absorbers are fixedly installed on one side surface of the first connecting rod and the second connecting rod.

[0012] As a further solution of the present utility model: One end of the shock absorber away from the first connecting rod and the second connecting rod is fixedly connected to the bottom plate.

[0013] As a further solution of the present utility model: Plugging rods are rotatably installed at one ends of the first connecting rod and the second connecting rod away from the rotating rod, and the plugging rods are fixedly connected to the anti-collision rubber pads.

[0014] Compared with the prior art, the present utility model provides a linear module with high precision and anti-wear, and has the following beneficial effects:

[0015] 1. In the present utility model, when the staff turns on the driving device, the threaded rod rotates, and then drives the slider to move horizontally. At the same time, the guide rod penetrates through the slider and is slidably connected to the slider, so that the slider can slide more smoothly. Anti-collision rubber pads are provided on the corresponding two sides of the main frame, and the material of the anti-collision rubber pads is nitrile rubber, which has good damping. Therefore, the impact force of the slider hitting the anti-collision rubber pads can be converted into heat energy and consumed through its sliding to achieve the purpose of shock absorption, and then avoid the slider directly hitting the device provided on the main frame, resulting in wear of the slider and affecting the service life of the linear module.

[0016] 2. In the present utility model, when the anti-collision rubber pad is hit by the slider, the anti-collision rubber pad moves towards the bottom plate, and then drives the first connecting rod and the second connecting rod to rotate, so that the first connecting rod and the second connecting rod squeeze the shock absorber. The elastic force of the shock absorber drives the first connecting rod and the second connecting rod to rotate, and then the anti-collision rubber pad moves away from the bottom plate.

[0017] Parts not involved in the device are the same as or can be implemented by the prior art. The structure of the present utility model is simple and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0025] Embodiment: A high-precision anti-wear linear module, as Figures 1-4 shown, includes a main frame 1. Anti-collision rubber pads 8 are provided on both corresponding sides of the main frame 1. A guide block 3 is slidably installed at the bottom of the main frame 1. A slider 4 is fixedly installed on the upper surface of the guide block 3. The slider 4 is slidably connected to a guide rod 7. The slider 4 is threadedly engaged with a threaded rod 6. By slidably installing a guide block 3 at the bottom of the main frame 1 and fixedly installing a slider 4 on the upper surface of the guide block 3, when the guide block 3 slides, the slider 4 is driven to slide. And the slider 4 is slidably connected to a guide rod 7, and the slider 4 is threadedly engaged with a threaded rod 6. At the same time, the threaded rod 6 is connected to the provided driving device. Then, when the staff turns on the driving device, the threaded rod 6 rotates, and then drives the slider 4 to move horizontally. At the same time, the guide rod 7 passes through the slider 4 and is slidably connected to the slider 4. Therefore, the slider 4 can slide more smoothly. By providing anti-collision rubber pads 8 on both corresponding sides of the main frame 1, and the material of the anti-collision rubber pads 8 is nitrile rubber, which has good damping properties. Thus, the impact force of the slider 4 hitting the anti-collision rubber pad 8 can be dissipated as heat through its sliding, so as to achieve the purpose of shock absorption. Then, it is avoided that the slider 4 directly hits the device provided on the main frame 1, resulting in wear of the slider 4 and affecting the service life of the linear module.

[0026] As Figures 1-4As shown in the figure, both ends of the guide rod 7 are fixedly connected to the main frame 1. One end of the main frame 1 is fixedly installed with a driving device 5. The output end of the driving device 5 is fixedly connected to the threaded rod 6. The threaded rod 6 is rotatably connected to the main frame 1. The bottom surface of the main frame 1 is fixedly installed with a guide rail 2. The guide rail 2 is slidably connected to the guide block 3. By setting the driving device 5, and the output end of the driving device 5 is fixedly connected to the threaded rod 6, and at the same time the threaded rod 6 is screwed with the slider 4, when the staff turns on the driving device 5, the threaded rod 6 rotates, and then drives the slider 4 to move horizontally. At the same time, the guide rod 7 passes through the slider 4 and is slidably connected to the slider 4, so that the slider 4 can slide more smoothly. At the same time, the guide block 3 is slidably connected to the guide rail 2. When the slider 4 moves horizontally, it drives the guide block 3 to slide on the guide rail 2.

[0027] As Figures 1-4 shown in the figure, a plurality of bottom plates 9 are fixedly installed on both corresponding sides of the main frame 1. Every four bottom plates 9 form a group. A rotating rod 10 is fixedly installed on the bottom plate 9. A first connecting rod 11 and a second connecting rod 12 are rotatably installed on the rotating rod 10. The first connecting rod 11 is rotatably connected to the second connecting rod 12. Shock absorbers 15 are fixedly installed on one side surface of the first connecting rod 11 and the second connecting rod 12. By setting that one end of the first connecting rod 11 and the second connecting rod 12 is rotatably connected to the rotating rod 10, and the other ends of the first connecting rod 11 and the second connecting rod 12 are connected to the anti-collision rubber pad 8 through a connecting device. When the anti-collision rubber pad 8 is hit by the slider 4, the anti-collision rubber pad 8 moves towards the bottom plate 9, and then drives the first connecting rod 11 and the second connecting rod 12 to move. And a hole groove is provided on the second connecting rod 12. The first connecting rod 11 passes through the hole groove. At the same time, a rotating rod is rotatably installed between the first connecting rod 11 and the second connecting rod 12. When the anti-collision rubber pad 8 moves towards the bottom plate 9, the first connecting rod 11 and the second connecting rod 12 rotate, so that the first connecting rod 11 and the second connecting rod 12 squeeze the shock absorber 15. The elastic force of the shock absorber 15 drives the first connecting rod 11 and the second connecting rod 12 to rotate, and then the anti-collision rubber pad 8 moves away from the bottom plate 9, so that the impact force of the slider 4 hitting the anti-collision rubber pad 8 can be dissipated as heat through its sliding to achieve the purpose of shock absorption.

[0028] As Figures 1-4As shown in the figure, one end of the shock absorber 15 away from the first connecting rod 11 and the second connecting rod 12 is fixedly connected to the bottom plate 9. One end of the first connecting rod 11 and the second connecting rod 12 away from the rotating rod 10 is rotatably installed with a plugging rod 14. The plugging rod 14 is fixedly connected to the anti-collision rubber pad 8. By setting that the first connecting rod 11 and the second connecting rod 12 are connected to the anti-collision rubber pad 8 through the plugging rod 14, when the anti-collision rubber pad 8 moves towards the bottom plate 9, it drives the first connecting rod 11 and the second connecting rod 12 to rotate and squeeze the shock absorber 15. Then the shock absorber 15 works. Thus, through the elastic force of the shock absorber 15, the first connecting rod 11 and the second connecting rod 12 rotate, and then the anti-collision rubber pad 8 moves away from the bottom plate 9, providing a shock absorption for the impact on the slider 4.

[0029] Working principle: When the staff opens the driving device, the threaded rod 6 rotates, and then drives the slider 4 to move horizontally. At the same time, the guide rod 7 passes through the slider 4 and is slidably connected to the slider 4, so that the slider 4 can slide more smoothly. When the anti-collision rubber pad 8 is impacted by the slider 4, the anti-collision rubber pad 8 moves towards the bottom plate 9, and then drives the first connecting rod 11 and the second connecting rod 12 to move. There is a hole groove on the second connecting rod 12, and the first connecting rod 11 passes through the hole groove. At the same time, a rotating rod is rotatably installed between the first connecting rod 11 and the second connecting rod 12. When the anti-collision rubber pad 8 moves towards the bottom plate 9, the first connecting rod 11 and the second connecting rod 12 rotate, so that the first connecting rod 11 and the second connecting rod 12 squeeze the shock absorber 15. Through the elastic force of the shock absorber 15, the first connecting rod 11 and the second connecting rod 12 are driven to rotate, and then the anti-collision rubber pad 8 moves away from the bottom plate 9. Thus, the impact force of the slider 4 hitting the anti-collision rubber pad 8 can be converted into heat energy and consumed through its sliding to achieve the purpose of shock absorption.

[0030] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
