Description

Compound dustproof structure of linear slider

This creation is about a linear slider, especially a composite dustproof structure with a non-contact dustproof structure and a linear slider with a contact-type dustproof structure that can be optionally added at the position of the linear slider corresponding to the linear slide rail .

The linear slider currently used on linear slides is usually composed of a body, two circulators, a majority of rollers and a dust cover. The roller slides in the track of the seat body and the two-end circulator, so that the linear slider can Move smoothly on linear slides. Among them, the dust cover is usually combined with the end of the circulator to form the dustproof structure of the end of the linear slide device. The dust cover is formed with a ㄇ-shaped convex edge matching the shape of the linear slide rail. The convex edge is used for the linear slide device on the linear slide rail When moving, scrape the processing dust or foreign matter on the surface of the linear slide to prevent it from being caught in the running area of the roller on the linear slide, which interferes with the smooth rolling of the roller under high-speed motion, which causes linear sliding The device fails and is damaged.

However, in addition to the intrusion of processing dust or foreign objects from the direction in which the linear slider travels on the linear slide, it will also invade the roller from the bottom end surface of the linear slide or the periphery of the screw hole on the upper surface of the linear slide to the linear slide Run area on the block. For this reason, the traditional linear slider has various types of lower dustproof and upper dustproof structures, which are respectively provided at the bottom of the seat body and the upper end of the rail groove of the seat body, as shown in, for example, Chinese Patent Announcements CN101612625, CN101025197, CN201241917, CN103883620. Know dustproof structure.

The technology disclosed in the above patents is to move the dustproof structure against the top surface and both sides of the linear slide rail, thereby preventing the intrusion of dust or foreign objects. However, the environmental conditions and dust-proof requirements of linear sliders and linear slides in the industry are different. Many precision machining fields require linear sliders to have a precise and comprehensive dust-proof structure. There are also other applications where there is no dust and foreign objects (such as dust-free Room) or the dustproof effect is not high, so there is no need to use precision dustproof and expensive linear sliders, so the traditional industry must manufacture two dustproof linear sliders for the industry to choose, but the manufacture of two dustproof linear specifications The slider is not an ideal industrial supply solution. Therefore, how to make the dustproof structure of the linear slider more flexible to meet the needs of the industry is the subject to be actively overcome for this creation.

The purpose of this creation is to provide a composite dust-proof structure of linear sliders, and then to meet the industrial needs that can provide two different precision dust-proof structures, reduce manufacturing assembly and procurement costs, and easily assemble dust-proof strips.

In order to achieve the above purpose, the composite dust-proof structure of the linear slider created in this invention includes a slider body, two sets of circulators combined at both ends of the slider body, and most of them are arranged on the slider body and the The roller in the circulator is characterized in that: the slider body includes a base body and a covering body; a bottom surface of the base body is concavely provided with a first rail groove for sheathing on a linear slide rail, the A load rail is formed on both sides of the first rail groove; the cladding body has two end blocks formed on the two end surfaces of the seat body, connected between the two end blocks and coupled to an inner top surface of the first rail groove An upper wall, and two side walls connected between the two end blocks and combined with the two inner sides of the first rail groove; the upper wall has an upper dust strip mounting portion, and both sides of the upper dust strip mounting portion are integrated A non-contact upper dustproof lip is formed, and an upper gap is reserved between the upper dustproof lip and the top surface of the linear slide rail; the side wall has a side dust strip mounting portion, and both sides of the side dust strip mounting portion A non-contact side dustproof lip is integrally formed separately, and a side gap is reserved between the side dustproof lip and the top surface of the linear slide rail.

In this way, the composite dustproof structure of the linear slider can be integrally molded with the upper dustproof lip and the side dustproof lip by the covering body, so that the linear slider has the basic dustproof function and meets the lower dustproof specifications The industry's demand, because of its integrally molded structure, can reduce manufacturing and industrial procurement costs. In addition, when high-precision contact-type dustproof requirements are required, the contact-type dustproof strip can be easily installed on the upper dustproof strip mounting part and the side dustproof strip mounting part integrally molded by the covering body, so that the dustproof strip can resist Relying on the linear slide rail to achieve a high dustproof effect, it can also meet the industrial requirements of high dustproof specifications.

In the above composite dustproof structure of linear slider, the upper dustproof strip mounting portion and the side dustproof strip mounting portion are respectively a buckle groove, and the buckle groove extends to the end surface of the two end blocks. With this, the effect of quickly and easily loading the dustproof strip from one end can be achieved.

In the above composite dustproof structure of the linear slider, the buckle groove is one of a semicircular groove, a T-shaped groove or a dovetail groove. In this way, the dustproof strip is assembled in the semicircular groove, T-shaped groove or dovetail groove, which can achieve the effects of preventing the dustproof strip from falling off and eliminating the need for fixing components.

In the above composite dustproof structure of the linear slider, the upper dustproof strip mounting portion and the side dustproof strip mounting portion respectively assemble a contact type dustproof strip for abutting against the linear slide rail, and the dustproof strip extends to the The end faces of the two end blocks. With this structure, the dust-proof strip extends to the end surfaces of the two end blocks to achieve a comprehensive dust-proof effect.

In the above composite dustproof structure of the linear slider, the circulator has a pair of second rail grooves corresponding to the first rail groove, the upper wall of the second rail groove is formed with the upper dust strip mounting portion and the upper dust lip The side wall of the second rail groove is formed with the side dustproof strip mounting portion and the side dustproof lip. In this way, the effect that the circulator also has a non-contact dust-proof structure and a contact dust-proof structure can be achieved.

In the above composite dustproof structure of linear sliders, both ends of the dustproof strip extend to the upper dustproof strip mounting portion and the side dustproof strip mounting portion of the circulator. Therefore, the structure of the dustproof strip is extended to achieve a comprehensive dustproof effect.

The structural features, other functions and purposes of this creation are described in detail in the following embodiments according to the attached drawings:

Referring to FIG. 1, the composite dustproof structure of the linear slider is created. The linear slider 100 is used to slide the sleeve on a linear slide 200 to repeatedly slide linearly; and as shown in FIG. 2, the linear slider A preferred embodiment of 100 includes: a slider body 10, two sets of circulators 20 combined at both ends of the slider body 10, and a plurality of rollers 30 disposed in the slider body 10 and the circulator 20.
