Abstract
The invention discloses a high-precision adjustable round guide rail cart. The high-precision adjustable round guide rail cart comprises a cart bottom plate, cart lateral plates, a bearing seat assembly, an elastic wheel assembly and guide bearings, and is characterized in that the bearing seat assembly and the elastic wheel assembly are installed at the two ends of the cart bottom plate through bolts respectively, the guide bearings are fixed to the cart lateral plates through lead screws, and the bearing seat assembly, the elastic wheel assembly, the guide bearings installed on the cart lateral plates and a round guide rail jointly form a moving body capable of reciprocating linearly along the round guide rail. The high-precision adjustable round guide rail cart is reasonable in structure, easy to manufacture and convenient to install and adjust, largely improves the scanning accuracy of automatic scanning equipment and largely increases the load bearing capacity.
Description
Technical field
The present invention relates to a kind of round guide vehicle structure for automatic scanning equipment, belong to machinery manufacturing technology field.
Background technique
Round guide dolly is for carrying the vitals of scanning device in automatic scanning equipment, and therefore, the precision of automatic scanning equipment to the movement locus of round guide dolly has very high requirement.Conventional guide rails vehicle structure often adopts one piece of slide rail to be connected with dolly, or be connected with guide rail by 2 little bearings, adopt the round guide dolly of these two kinds of structures, its topmost shortcoming is: the round guide dolly after installation can not adjust, in addition the precision of round guide itself is lower, greatly have impact on the scanning accuracy of automatic scanning equipment thus.
Summary of the invention
In view of above-mentioned Problems existing, the object of this invention is to provide a kind of rational in infrastructure, make easily, install, easy to adjust, and the adjustable round guide dolly of the highi degree of accuracy of automatic scanning equipment scanning accuracy can be guaranteed.
For achieving the above object, this invention takes following technological scheme:
A kind of highi degree of accuracy of the present invention is adjustable round guide dolly, include cart base plate, dolly side plate, bearing block assembly, elastic wheel assembly, guide bearing, it is characterized in that bearing block assembly and elastic wheel assembly are arranged on the two ends of cart base plate respectively by bolt, guide bearing is fixed on dolly side plate by screw rod, and bearing block assembly, elastic wheel assembly and the guide bearing be arranged on dolly side plate and round guide form the moving whole that can do reciprocating linear motion along round guide jointly.
As preferably, described bearing block assembly, is made up of big uncork type linear bearing and bearing cap, and the opening slot of big uncork type linear bearing and the supporting base of guide rail match, and round guide is sleeved in big uncork type linear bearing assembly.
As preferably, described elastic wheel assembly is made up of elastic wheel bearing, bearing support, straight pin, spring, bearing and elastic wheel base plate, elastic wheel bearing is fixed on bearing support by a straight pin, and spring fitting is in bearing support, and bearing support and bearing are Spielpassung; Bearing support is flexible connection by spring and elastic wheel base plate; Elastic wheel bearing keeps good contact by spring and round guide moment, thus ensure that dolly has very high kinematic accuracy.
As preferably, described is eccentric screw for the wherein screw rod installed in two guide bearings, by rotating eccentric adjustment screw rod, can ensure that two linear bearings be fixed in the bearing block assembly on cart base plate are coplanar with two guide bearings 4 be fixed on dolly side plate, greatly can improve the kinematic accuracy of dolly thus, also considerably increase the load capacity of dolly simultaneously.
The present invention after above-mentioned design, rational in infrastructure, make easily, install, easy to adjust, it not only substantially increases the scanning accuracy of automatic scanning equipment, and considerably increases the load capacity of round guide dolly.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described:
With reference to accompanying drawing, the described adjustable round guide dolly of a kind of highi degree of accuracy of the present invention, includes cart base plate 4, dolly side plate 7, bearing block assembly 3, elastic wheel assembly 5, guide bearing 6; Bearing block assembly 3 and elastic wheel assembly 5 are arranged on the two ends of cart base plate 4 respectively by bolt, guide bearing 6 is fixed on dolly side plate 7 by screw rod 8, and bearing block assembly 3, elastic wheel assembly 5 and the guide bearing 6 being arranged on dolly side plate 7 form the moving whole that can do reciprocating linear motion along round guide jointly with round guide 2.
In order to ensure the kinematic accuracy of round guide dolly, the linear bearing in described bearing block assembly 3 adopts big uncork type, and the supporting base of its opening slot and guide rail matches.During installation, the two ends bearing cap 1 of bearing support is fixed, and moves axially to prevent linear bearing.
The elastic wheel assembly 5 of highi degree of accuracy is adjustable round guide dolly is made up of elastic wheel bearing 10, bearing support 9, straight pin 11, spring 12, bearing 13 and elastic wheel base plate 14, elastic wheel bearing 10 is fixed on bearing support 9 by straight pin 11, spring 12 is arranged in bearing support 9, and bearing support 9 and bearing 13 are in Spielpassung; Bearing support 9 is flexible connection by spring 12 and elastic wheel base plate 14; Elastic wheel bearing 10 keeps good contact by spring 12 and round guide 2 moment, thus ensure that moving of car has very high kinematic accuracy.
For ease of the install and adjust of round guide not car, described is eccentric screw for the wherein screw rod 8 installed in two guide bearings 6, by rotating eccentric adjustment screw rod, can ensure that two linear bearings be fixed in the bearing block assembly 3 on cart base plate 4 are coplanar with two guide bearings 6 four be fixed on dolly side plate 7, greatly can improve the kinematic accuracy of dolly thus, also considerably increase the load capacity of dolly simultaneously.
During installation, first 2 bearing block assemblies 3 are inserted in side round guide 2, trolley base plate 4 is fixed by bolts on bearing support, elastic wheel assembly 5 is fixed on cart base plate 4, contact with round guide 2, a guide bearing 6 is separately had to be fixed on dolly side plate 7 by screw rod 8, in the screw rod 8 of two guide bearings wherein one be eccentric shaft, can ensure that two linear bearings in bearing block assembly 3 and two upper saw pulleys 6 are all in same plane like this, this Placement considerably increases the load capacity of dolly, by cart base plate, these parts composition dolly entirety can be done reciprocating linear motion on round guide again.
