Abstract

The utility model discloses a high -accuracy synchronous alternately roller guide, including screw end cover, holder, roll post, V type slide rail, gyration dabber and synchronous gear, the guide rail is put together by two V type slide rails, the holder sets up in the middle of two mating V type grooves of V type slide rail, the roll post is installed in a plurality of round holes of the 90 degrees contained angle orientations of achieving success are opened to the holder, the V type tank bottom portion of V type slide rail has seted up one row of tooth's socket, synchronous gear installs at the gyration spindle, and just the V type tank bottom portion with V type slide rail has seted up one row of toothed grooves meshing with. This high -accuracy synchronous alternately roller guide has one row of tooth's socket in the processing of the V type tank bottom portion of V type slide rail, utilizes the rotary dabber of arranging in the middle of the holder and two V type slide rails that synchronous gear will do the relative slip to mesh, drives the holder and does two V type slide rail hold ins of relative slip, and messenger's holder does not take place to skid at two V type slide rail relative slip in -processs.

Description

A kind of high-accuracy synchronous intersection roller guide

Technical field

The utility model relates to the field of machinery automation such as precision machine tool, precision coordinate measuring machine, high-accuracy sliding platform, is specially a kind of high-accuracy synchronous intersection roller guide.

Background technique

High-accuracy decussation roller guide rail, very general in field of machinery automation application such as precision machine tool, precision coordinate measuring machine, high-accuracy sliding platforms.

Existing high-accuracy decussation roller guide rail, there is the phenomenon of asynchronous (skidding) in V-type rail V-type slide rail and retainer in relative movement, has the critical defect of off-design stroke gradually; The equipment that affects slides and normally uses.

Model utility content

The purpose of this utility model is to provide a kind of high-accuracy synchronous intersection roller guide, and its structure is simple, practical, compensate for the deficiencies in the prior art.

For achieving the above object, the utility model provides following technological scheme: a kind of high-accuracy synchronous intersection roller guide, comprises screw end cap, retainer, rolling post, V-type slide rail, revolution mandrel and synchromesh gear; Guide rail is combined by two V-type slide rail set, and described retainer is arranged in the middle of the V-type groove of two V-type slide rail pairings; Described rolling post is arranged on retainer and has in multiple circular holes in 90 degree of angle directions; The V-type groove bottom of described V-type slide rail offers a toothrow groove; Described synchromesh gear is arranged on revolution mandrel, and engages with the toothrow groove that the V-type groove bottom of V-type slide rail is offered.

Further, described retainer neutral position offers a pair circular hole and is used for fixing revolution mandrel; Offer a waist type groove to be used for arranging synchromesh gear.

Compared with prior art, the beneficial effects of the utility model are: this high-accuracy synchronous intersection roller guide, a toothrow groove is processed with at the V-type groove bottom of V-type slide rail, utilize and be arranged in two V-type slide rails engagements that revolution mandrel in the middle of retainer and synchromesh gear will do relative sliding, drive retainer to keep synchronous with two the V-type slide rails doing relative sliding, retainer is not skidded in two V-type slide rail relative sliding processes.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1 ~ 4, the utility model provides a kind of technological scheme: a kind of high-accuracy synchronous intersection roller guide, comprises screw end cap 1, retainer 2, rolling post 3, V-type slide rail 4, revolution mandrel 5 and synchromesh gear 6; Guide rail is combined by two V-type slide rails 4, and described retainer 2 is arranged in the middle of the V-type groove of two V-type slide rails 4 pairings; Described rolling post 3 is arranged in retainer 2 and has in multiple circular holes in 90 degree of angle directions; The V-type groove bottom of described V-type slide rail 4 offers a toothrow groove; Described synchromesh gear 6 is arranged on revolution mandrel 5, and offers a toothrow groove with the V-type groove bottom of V-type slide rail 4 and engage.

The utility model is when designing: increase by a toothrow groove at the V-type groove bottom of V-type slide rail 4; A pair circular hole and a waist type groove is added in retainer neutral position, place revolution mandrel 5 and synchromesh gear 6, when two V-type slide rails are when doing relative motion, the synchromesh gear 6 meeting wraparound be arranged in the middle of retainer 2 turns mandrel 5 and freely rotates, gear both sides tooth engages with the teeth groove of two slide rail V groove bottoms respectively simultaneously, drive retainer to keep synchronous with two the V-type slide rails 4 doing relative sliding, do not skid.

Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
