Technical Field
[0001] The utility model relates to the technical field of sliders, in particular to a dustproof linear guide slider. Background Art
[0002] Sliders are widely used in precision machine tools, but the internal processing is difficult and the high precision requirements make processing difficult. The sliding principle of square rail slides mainly relies on the circulation of steel balls in the grooves of the slide rails.
[0003] When the slider moves linearly on the guide rail, dust, iron filings, grinding wheel dust, dirty oil, debris, etc. will fall on the surface of the guide rail. In order to prevent various pollutants from entering the interior of the slider and affecting the accuracy, performance and life of the slider, baffles are provided on both sides of the inner wall of the slider. However, during the reciprocating motion, dust, iron filings, grinding wheel dust, dirty oil, and debris will accumulate on the surface of the baffle, and then spread to the outer edge of the baffle, and then enter the gap between the baffle and the slider, causing the baffle to bulge at a certain point, interfering with the normal movement of the slider. Therefore, the applicant has made a useful design and found a solution to the above-mentioned problem. The technical solution to be introduced below was produced in this context. Summary of the invention

[0005] To solve the above problems, the utility model adopts the following technical solutions.
[0006] A dustproof linear guide slider comprises a slider, a circulator fixed at both ends of the slider, and a ball chain slidably arranged in the circulator, the slider is provided with a slide groove for the guide rail to move, the ball chain is also slidably arranged on both sides and above and below the slide groove, baffles are provided on both sides of the entrance of the slide groove, one side of the baffle is provided with an inclined portion, the inclined portion is extended to provide an interference portion, the top of the baffle is provided with a dustproof sheet, one side of the dustproof sheet is provided with a raised baffle facing the slide groove.
[0007] Preferably, both sides of the entrance of the circulator and the slide are provided with yield grooves.
[0008] Preferably, the blocking piece is arranged in the clearance groove.
[0009] Preferably, the circulator is provided with a blocking cover which abuts against a blocking sheet.
[0010] Preferably, the inner wall of the abutment portion is provided with a fitting portion, and abuts against the balls of the ball chain.
[0011] Beneficial effects:
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model prevents dust, iron filings, grinding wheel dust, dirty oil, sundries and other dirt generated during the reciprocating motion of the slider from spreading between the baffle and the yield groove through the inclined portion, and further prevents the dirt from spreading through the raised baffle, thereby overcoming the problems raised by the background technology, avoiding the baffle from protruding somewhere and interfering with the normal movement of the slider, and making the product dust-proof and anti-accumulation.

[0020] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are 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 direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0022] In the embodiment of the present invention, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.
[0023] Reference example Figures 1 to 4 , a dustproof linear guide slider, comprising a slider 1, a circulator 2 fixed at both ends of the slider 1, and a ball chain 3 slidably arranged in the circulator 2, the slider 1 is provided with a slide groove 11 for the guide rail 8 to move, the ball chain 3 is also slidably arranged on both sides and upper and lower parts of the slide groove 11, baffles 4 are arranged on both sides of the entrance of the slide groove 11, one side of the baffle 4 is provided with an inclined portion 41, and the inclined portion 41 is extended to be provided with a resistance portion 42, a dustproof sheet 5 is arranged on the top of the baffle 4, and one side of the dustproof sheet 5 is provided with a raised baffle 51, and faces the slide groove 11, and the inclined portion 41 is used to prevent the dust, iron filings, grinding wheel dust, dirty oil, sundries and other dirt generated during the reciprocating motion of the slider 1 from spreading between the baffle 4 and the yield groove 6, and the raised baffle 51 is used to further prevent the dirt from spreading, thereby overcoming the problems raised by the background technology, and avoiding the baffle 4 from protruding somewhere and interfering with the normal movement of the slider 1;
[0024] It is worth mentioning that the circulator 2 and the chute 11 are provided with a clearance groove 6 on both sides of the entrance, and the clearance groove 6 provides a positioning function for the fixing of the baffle 4, and at the same time, provides a support point for the baffle 4;
[0025] It is worth mentioning that the baffle 4 is arranged in the yield groove 6, which not only plays a role in dust prevention, but also plays a role in preventing the chain edge of the ball chain 3 from contacting and generating friction with the guide rail 8, thereby reducing the noise of the slider 1 moving on the guide rail 8;
[0026] It is worth mentioning that the circulator 2 is provided with a blocking cover 7, which abuts against the blocking piece 4. The blocking cover 7 plays a role in fixing the blocking piece 4 to prevent the blocking piece 4 from being affected by the linear motion of the slider 1 and causing left-right displacement or direct separation.
[0027] It is worth mentioning that the inner wall of the resistance part 42 is provided with a fitting part 43, which abuts against the balls of the ball chain 3. The resistance part 42 limits the left and right displacement of the slider 1 on the guide rail 8, so that the slider 1 can move smoothly in a straight line on the guide rail 8, and the fitting part 43 provides a guiding function for the ball chain 3.
[0028] The above design scheme can enable the product to achieve the advantages of dust prevention and anti-accumulation.
