Description

The linear slide rail of tool outer hanging type inductor

Technical field

The present invention relates to a kind of linear slide rail, refer to a kind of linear slide rail of tool outer hanging type inductor especially.

Background technique

" a kind of linear slide rail of the tool magnetic induction chi function " patent of invention (hereinafter to be referred as known case) that sees also the U.S. 6333628B1 number, but this known case is a kind of feedback slide block position or the creation that calculates the slider displacement distance, it is to borrow magnetic induction part to be arranged at end cap and tape is arranged at directly over the rail bar, can reach the processing cost that does not increase slide block, and make the effect of no variable in distance between tape and magnetic induction part.Yet this known case but must be fixed in the slide block both sides with two kinds of heteroid end caps, makes the end covers at two sides can't be shared, on making, must offer two secondary moulds or through the problem of the expensive expenditure of twice procedure, and remain to be improved again.

Summary of the invention

At the deficiency of case before the above-mentioned patent, main purpose of the present invention is to provide a kind of linear slide rail of tool outer hanging type inductor, and its slide block end covers at two sides structure is identical and can be shared, offers the cost of mould and dual processing end cap with reduction.

Secondary objective of the present invention is to provide a kind of linear slide rail of tool outer hanging type inductor, and its inductor can make the applicability of inductor more extensive in response to the slide rail and the slide block of different size.

For reaching the foregoing invention purpose, technical solution of the present invention is:

A kind of linear slide rail of tool outer hanging type inductor, the slide block both sides of this slide rail respectively are provided with an end cap, and the slide rail upper-end surface is provided with a magnetic scale, and this slide block can be in the slide rail top offset; One inductor is locked on the wherein corresponding with the magnetic scale of being located at the slide rail upper-end surface above the end cap of above-mentioned two end cap, to read the position of magnetic scale; This inductor is made up of first pedestal, second pedestal and sense cell, and wherein, this second pedestal is locked on the above-mentioned end cap, and this first pedestal is limited to sense cell wherein with this second pedestal hasp.

Folder is established an oil-scrapping sheet between the end cap that described inductor and quilt lock are established, so that the dustproof effect of this slide block tool.

The end cap that described lock is established inductor is provided with the oil nozzle hole of a tool internal thread, and the lock mode of establishing of this second pedestal and this end cap is to be locked in the oil nozzle hole of end cap with screw.

Described inductor forms a protrusion embedding seat with respect to the side of oil-scrapping sheet, and the side of the relative embedding seat of oil-scrapping sheet then forms a groove and is embedded at wherein for this embedding seat.

Described oil-scrapping sheet has a perforation, this end cap is provided with the oil nozzle hole of a tool internal thread with respect to perforation place of oil-scrapping sheet, the L-shaped lamellar body of this first pedestal, and tool one stringer board and a transverse slat, transverse slat is provided with a groove, sense cell is inserted in this groove, and this sense cell comprises an induction piece and a RCA; This second pedestal has a putting chamber, the putting chamber dorsal part is provided with a pertusate embedding seat, and this second pedestal by putting chamber, passes the perforation of embedding seat and the perforation of oil-scrapping sheet for a screw again, screw lock is in the oil nozzle hole of end cap, and this first pedestal is pulled with the corresponding folder of second pedestal.

The thickness of the described first pedestal transverse slat and the degree of depth of groove make the bottom portion of groove of this transverse slat and the distance that the slide rail upper-end surface is maintained fixed along with the oil nozzle hole of the end cap distance to the slide rail upper-end surface changes and changes.

The stringer board of described first pedestal forms a moulding that protrudes with respect to the side of second pedestal, and two pedestals are to fashionable, and the moulding of this first pedestal just closely is placed in the putting chamber of second pedestal.

After adopting such scheme, the present invention makes linear slide rail optionally select whether carry additionally inductor, and must not make the slide block and the end cap of special construction in addition, makes whole group linear slide rail or slide block, end cap can reach shared effect; It is with inductor design for by the involutory hasp of two pedestals in together the time, sense cell is limited to wherein, borrow wherein a pedestal screw lock to be fixed in wherein on the end cap, reach the effect of ease of assembly, simultaneously can be in response to different size slide block or slide rail by means of a pedestal, thereby this pedestal of replaceable different size is kept necessarily the distance between sense cell and magnetic scale, and then is guaranteed its validity.

Particularly, the following advantage of the real tool of the present invention:

1, slide block and two end cap must not offered dual mould in addition or through twice different procedure, reduce the manufacture cost of linear slide rail.

2, because inductor adopts external hanging type, make linear slide rail can optionally select whether to possess the function of detecting slider displacement distance, have stronger mobility, and the stock is reduced.

3, as easy as rolling off a log assembling of inductor and dismounting can not influence the installation of linear slide rail and facility.

4, borrowing inductor is design by first pedestal and the mutual involutory hasp of second pedestal, first pedestal can be replaced, when changing the transverse slat thickness of first pedestal, can be in response to the slide rail and the slide block of different size, distance between induction piece and magnetic scale is kept necessarily, thereby guaranteed the validity of the numerical value of detecting.
