Description

The linear slide rail of dustproof element on tool

Technical field

The present invention is a kind of linear slide rail equipment, particularly relate to a kind of dust-proof structure of slider of linear slide rail, it can strike off the greasy dirt of slide rail upper surface with flexible lip at any time and prevent foreign matter from entering above-listed steel ball groove from slide rail upper surface, reach preferably dust reduction capability and ensure linear slide rail service life.

Background technology

Because Linear transmission component products are more and more extensive in the operation strategies of modern industry, various Linear transmission component products widely enter within human lives, processing factory and high technology equipment, for example：Linear slide rail, ball screw etc.；Big and small different linear slide rail systems are more installed among particularly general large-scale precision equipment, although the development of Linear transmission Element Technology is very rapid, but consumption user still needs technology and constantly lifted, therefore many problems still leaved for development are also produced, particularly it is many need relatively to stablize, quietly high-accuracy manufacturing industry equipment field more constantly have the improved voice of research and development, therefore some techno peasant's point poles of Linear transmission element treat that personage adds research and development to improve again at present.

Current general linear slide rail enters at the rolling element in sliding block for the laying dust or greasy dirt of anti-anti-slip track overhead surface, and the usual producer can be equiped with dustproof construction by the above-listed steel ball groove of correspondence on the upside of the sliding block inwall of linear slide rail；Common dustproof construction No. 4918846 invention cases of U.S. Patent No. as shown in Figure 5, in sliding block end with the dust-proof U-shaped metallic plate 10 of screwed lock intrinsic one, the U-shaped metallic plate 10 uses spring steel punch forming, dustproof sheet lip 11 is fixed on the both sides of the edge of metallic plate 10 again (fixed form can adopt laminating positioning), and the locking mode between metallic plate 10 and sliding block is divided to two parts, one is drilling is positioned for metallic plate 10 to screw of locking on slider body, another part is to coordinate the locking positioning of oil nozzle element in sliding block outer end, this commonly uses the laying dust or greasy dirt for stopping slide rail overhead surface with dustproof sheet lip 11；But after practicality the dustproof construction, because needing to use multiple screws to be locked, and part is also needed using oil nozzle collocation locking metallic plate 10, and linkage editor is numerous and diverse, and its manufacturing cost is at a relatively high, does not meet economic benefit, therefore real has necessity that improvement progresses greatly.

The content of the invention

In view of above mentioned problem, present invention is primarily aimed at：A kind of versatility height is researched and developed, and is not required to the upper dustproof element of screw locking.

To reach above-mentioned purpose, solution of the invention is：

The linear slide rail of dustproof element on a kind of tool, comprising：One rail bar, it extends to strip structure towards a direction, defines the bearing of trend for direction of principal axis, the rail bar is respectively equipped with multiple rolling channels and a retaining lugs in the both sides of direction of principal axis；One sliding block module is sheathed on the rail bar and can back and forth run with respect to the rail bar, and the sliding block module has top surface and the slot being extended by the direction of principal axis both sides of upper top surface on one；Dustproof element on one, with one with the body for closing top surface, the holding section extended by the body towards direction of principal axis both sides, the holding section is embedded at the slot, and there is a contact end to be contacted with the retaining lugs for the holding section, the body to should the upper surface of rail bar be provided with the dirt lips of two settings at a distance, the end of the dirt lip and the upper surface.

Further, the general U-shaped shape of the retaining lugs, the general C-shaped shape of the slot and holding section.

Further, the sliding block module has slider body, multiple rolling members, two end cap and end dustproof sheet, the slider body have it is multiple to should rolling channel set rolling groove, the rolling channel and rolling groove constitute a load path, multiple rolling members are arranged at the load path, two end caps are respectively arranged at the direction of principal axis both ends of the surface of the slider body, the end cap provides multiple rolling member circulating refluxs, the end dustproof sheet is arranged at the end cap, and the end dustproof sheet is provided with a lip contacted with the surface of the rail bar.

Further, the holding section extends towards the two end dustproof sheet directions respectively, and is contradicted with the end dustproof sheet.

Being collocated with each other by above-mentioned technical characteristic of the invention; dustproof element on this is set to be fixed in the sliding block module by the cooperation between holding section and slot; and can provide twice by the setting of the dirt lip and contact end prevents foreign matter from entering in the path that rolling member is run; to ensure the smooth operation of sliding block module energy, and lift the service life of sliding block module.

Embodiment

In order to which technical scheme is explained further, below by specific embodiment, the present invention will be described in detail.

Refer to shown in Fig. 1 to Fig. 4, the present invention is a kind of linear slide rail of dustproof element on tool, comprising：One rail bar 1, it extends to strip structure towards a direction, defines the bearing of trend for direction of principal axis X, the rail bar 1 is respectively equipped with multiple retaining lugs 12 of rolling channel 11 and one in direction of principal axis X both sides, the upper surface 13 of the rail bar is provided with multiple fixing holes 14, the general U-shaped shape of the retaining lugs 12；One sliding block module is sheathed on the rail bar 1 and can back and forth run with respect to the rail bar 1, the sliding block module has slider body 2, multiple rolling members 4, two end cap 3 and end dustproof sheet 31, the slider body 2 have it is multiple to should rolling channel 11 set rolling groove 21, the rolling channel 11 constitutes a load path with rolling groove 21, the load path provides multiple rolling members 4 and set, two end caps 3 are respectively arranged at the direction of principal axis X both ends of the surface of the slider body 2, in the present embodiment end cap 3 slider body 2 is locked in by multiple screw G, the end cap 3 provides multiple circulating refluxs of rolling member 4, the end dustproof sheet 31 is arranged at the end cap 3, and the end dustproof sheet 31 is provided with a lip 311 contacted with the surface of the rail bar 1, the slider body 2 has top surface 23 on one, and by the extended slot 22 in the direction of principal axis X both sides of upper top surface 23；Dustproof element 5 on one, with one with the body 51 for closing top surface 23, the holding section 52 extended by the body 51 towards direction of principal axis X both sides, the holding section 52 is embedded at the slot 22, the general C-shaped shape of the slot 22 and holding section 52, and there is a contact end 521 to be contacted with the retaining lugs 12 for the holding section 52, in order to allow the flexible suggestion in the holding section 52 to be manufactured using the metal material of plastic-steel material or tool elasticity, and it is proposed that carrying out the manufacture of dustproof element 5 on this using plastic cement injection molding method, 51 pairs of the body should the upper surface 13 of rail bar 1 be provided with the dirt lips 53 of two settings at a distance, the spacing distance of two dirt lips 53 is more than the diameter of the fixing hole 14, the end of the dirt lip 53 is contacted with the upper surface 13.Refer to shown in Fig. 4, in entering the load path that rolling member 4 is run between the end cap 3 and slider body 2 in order to avoid foreign matter, therefore extend respectively towards two directions of end dustproof sheet 31 in the present embodiment holding section 52, and contradicted with the end dustproof sheet 31, to form the dust-proof loop of a closing.
