Description

Technical Field

[0001] This utility model belongs to the field of ball screw slide technology, specifically a linear precision slide. Background Technology

[0002] As a core component for achieving high-precision linear motion, the operational stability and accuracy of a linear precision slide directly affect the overall working efficiency of the equipment. The ball screw, as a key transmission element of the slide, has its surface finish and transmission clearance crucial to motion accuracy. If the screw surface is contaminated with dust, debris, or other impurities, it will not only exacerbate friction and wear between the balls and raceways, leading to decreased transmission efficiency and accuracy drift, but long-term accumulation may also cause screw jamming, shortening the equipment's lifespan and increasing maintenance costs.

[0003] Traditional linear slides often employ integrated protective covers or long strip dust curtains for dust protection of ball screws. While these provide some protection, for miniaturized and lightweight precision slides, such designs tend to be complex, space-consuming, and difficult to disassemble. Especially when frequent inspections or maintenance of the ball screw are required, the cumbersome process of disassembling and assembling the integrated protective cover can interfere with the slide's installation accuracy and also increases the difficulty of cleaning the cover itself. Therefore, we propose a new linear precision slide. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 A linear precision slide includes a concave frame 1, inside which a ball screw 22 is rotatably mounted. An inverted V-shaped cover 14 is placed on the outside of the ball screw 22. The inverted V-shaped cover 14 effectively reduces the probability of external dust and debris contacting the ball screw 22, thereby ensuring the working accuracy of the ball screw 22. A mounting plate 13 is fixedly mounted on the right side of the inverted V-shaped cover 14. Two sets of pins 2 are evenly inserted between the mounting plate 13 and the concave frame 1. The top of the two sets of pins 2... A handle 16 is fixedly installed on the part, a high-strength spring 17 is placed on the outer ring of the pin 2, a magnetic block 21 is embedded in the bottom of the pin 2, the magnetic block 21 is magnetically attracted to the concave frame 1, a screw nut seat 11 is slidably installed inside the concave frame 1, a screw nut 18 is fixedly installed inside the screw nut seat 11, the screw nut 18 is screwed to the outside of the ball screw 22, a first clearance groove is opened through the right side of the screw nut seat 11, and a sealing gasket 19 is fixedly installed in the first clearance groove.

[0020] A second clearance groove is provided on the left side of the inner wall of the concave frame 1, a groove is provided on the right side of the concave frame 1, and a third clearance groove is provided through the left side of the groove. Two sets of guide rods 12 are evenly fixedly arranged on the inner wall of the concave frame 1. Two sets of guide holes are evenly provided through the right side of the screw nut seat 11. The guide rods 12 are slidably arranged in the guide holes, and a sealing ring 3 is fixedly arranged in the guide holes. The guide rods 12 pass through the sealing ring 3. The inverted V cover 14 is located between the two sets of guide rods 12. The mounting plate 13 is slidably arranged in the groove, and the inverted V cover 14 is slidably arranged in the first clearance groove. The left and right sides are respectively inserted into the second and third clearance grooves. The inner wall of the sealing gasket 19 fits against the outer wall of the inverted V cover 14. When the ball screw 22 rotates, the screw nut 18 drives the screw nut seat 11 to move linearly with the assistance of the guide rod 12. At the same time, the screw nut seat 11 drives the sealing gasket 19 and the sealing ring 3 to move synchronously. The sealing gasket 19 and the sealing ring 3 can seal the connection gap between the inverted V cover 14 and the guide rod 12 and the screw nut seat 11, thereby preventing external dust and debris from entering the connection gap and affecting the screw. To ensure the stability of the rod nut seat 11, two sets of through holes are evenly distributed through the top of the groove, and two sets of slots are evenly distributed through the bottom of the inner side wall of the groove. Two sets of insertion holes are evenly distributed through the top of the mounting plate 13. The bottom of the pin 2 passes through the through holes and insertion holes and is inserted into the slot. The magnetic block 21 is magnetically attracted into the slot. The handle 16 is located on the top right side of the concave frame 1. A high-strength spring 17 is fixedly installed between the handle 16 and the concave frame 1. A fourth clearance groove is opened on the right side of the mounting plate 13. A pull rod 15 is fixedly installed in the fourth clearance groove. The high-strength spring 17 utilizes its own rebound force to... The handle 16 drives the pin 2 through the through hole of the concave frame 1 and the insertion hole of the mounting plate 13 and inserts it into the slot of the concave frame 1. Then, the magnetic attraction of the magnetic block 21 in the slot improves the insertion stability of the pin 2, thereby fixing the mounting plate 13 stably in the groove of the concave frame 1, so that the inverted V cover 14 is stably fixed in the concave frame 1. After pulling the handle 16 upward to separate the pin 2 from the mounting plate 13, the inverted V cover 14 can be pulled out from the concave frame 1 by pulling the external rod 15 through the mounting plate 13 to move to the right. This achieves the effect of quick disassembly and assembly of the inverted V cover 14.

[0021] Working principle: The high-strength spring 17 uses its own rebound force to drive the pin 2 through the through hole of the concave frame 1 and the insertion hole of the mounting plate 13 via the handle 16 and insert it into the slot of the concave frame 1. Then, the magnetic attraction of the magnetic block 21 in the slot improves the insertion stability of the pin 2, thereby stably fixing the mounting plate 13 in the groove of the concave frame 1, thus stably fixing the inverted V cover 14 in the concave frame 1. When the ball screw 22 rotates, it drives the ball screw nut seat 11 to move linearly with the assistance of the guide rod 12 through the ball screw nut 18. At the same time, the ball screw nut seat 11 drives the sealing gasket 19 and the sealing ring 3 to move synchronously. The sealing gasket 19 and sealing ring 3 can seal the connection gap between the inverted V cover 14 and the guide rod 12 and the lead screw nut seat 11, thereby preventing external dust and debris from entering the connection gap and affecting the movement stability of the lead screw nut seat 11. The inverted V cover 14 can effectively reduce the probability of external dust and debris coming into contact with the ball screw 22, thereby ensuring the working accuracy of the ball screw 22. After pulling the handle 16 upward to separate the pin 2 from the mounting plate 13, the inverted V cover 14 can be pulled to the right through the mounting plate 13 by pulling the external pull rod 15, thus pulling it out of the concave frame 1, thereby achieving the effect of quick disassembly and assembly of the inverted V cover 14.
