Description
Technical field
The utility model relates to stage technology fields, in particular to a kind of eccentric shaft structure workbench.
Background technique
Conventional slip workbench is provided with slide block wheel, the slide block wheel and the guide rail contact on workbench, is guaranteeing work
Make under the enough machining accuracies of platform, whether in a plane the flatness of workbench depends on slide block wheel, this is just to workbench
The precision and assembly precision in top shoe hole have proposed very high requirement, and so, high production cost wants the technology of worker
It asks also very high, mostly uses eccentric shaft component at present, so as to adjusting slider wheel during the installation process, make slide block wheel in approximately the same plane
It is interior.
Utility model content
The utility model is intended to improve stage accuracy, reduces eccentric shaft cost.
In order to solve the above-mentioned technical problem, the utility model provides a kind of eccentric shaft structure workbench, including workbench,
Slide block wheel and eccentric shaft component are provided with multiple eccentric shaft components on the workbench, are arranged on each eccentric shaft component
There is the slide block wheel, the workbench is moved by the slide block wheel along guide rail, which is characterized in that the eccentric shaft component packet
Screw rod, eccentric bushing and hexagonal eccentric washer are included, the eccentric bushing is cased on the screw rod, described eccentric bushing a part is connected to institute
It states inside hexagonal eccentric washer, another part and the workbench clearance fit rotate the hexagonal eccentric washer, the hexagonal
Eccentric washer drives the eccentric bushing to rotate in the workbench.
Further, the eccentric bushing end surface shape includes inner edge and outer rim, and the inner circle is circle, the outer cause circle
Arc and one or more strings for deviateing inner circle surround.
Further, string there are three being set in the eccentric bushing outer rim.
Further, the slide block wheel is socketed in the eccentric shaft component ends and is equipped with bushing with the eccentric inner room.
Further, V-ring slot is provided on the slide block wheel periphery, the V-ring slot is matched with the guide rail.
Further, the workbench is in rectangle, and the rectangle is equipped with the eccentric shaft component close to quadrangle.
Further, annular gasket is equipped between the eccentric bushing and the bushing.
Further, the slide block wheel is fixed on the eccentric shaft component by round nut, the round nut with it is described
Spring shim is equipped between slide block wheel.
Further, the eccentric bushing material is Q235.
The utility model has the technical effect that the eccentric shaft component arrangement works platform, sets close to workbench four corners
Slide block wheel is set, is run smoothly, the setting of slide block wheel uses eccentric shaft part structures, effectively reduces the essence to workbench slider bore
The requirement of degree and assembly precision adds eccentric bushing and hexagonal eccentric washer to replace bias more importantly using common screw
Shaft member in adjustment process, adjusts the position that hexagonal eccentric washer is adjustable eccentric bushing, and then adjusting slider wheel, adjusts letter
Reducing singly while effectively production cost.
Detailed description of the invention
Fig. 1 is a kind of eccentric shaft structure workbench overall structure diagram according to the present utility model；
Fig. 2 is eccentric shaft component structural schematic diagram according to the present utility model；
Fig. 3 is eccentric bushing front view according to the present utility model.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model can be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
As shown in Fig. 1 to Fig. 3, a kind of eccentric shaft component arrangement works platform provided by the utility model, including workbench 1,
Slide block wheel 2 and eccentric shaft component 3 are provided with multiple eccentric shaft components 3 on workbench 1, are provided with cunning on each eccentric shaft component 3
Block wheel 2, slide block wheel 2 are fixed on eccentric shaft component 3 by round nut 31, and spring shim is equipped between round nut 31 and slide block wheel 2
32, slide block wheel can be effectively prevent to loosen.Specifically, workbench 1 is in rectangle, and rectangle is equipped with eccentric shaft component 3, sliding block close to quadrangle
Wheel 2 is socketed in 3 end of eccentric shaft component and is equipped with bushing 37 with eccentric inner room, is provided with V-ring slot 21 on 2 periphery of slide block wheel,
Annular groove 21 and guide rail contact, workbench 1 are moved by slide block wheel 2 along guide rail.Eccentric shaft component 3 includes screw rod 33, eccentric bushing
34 and hexagonal eccentric washer 35, eccentric bushing 34 is cased on screw rod 33, and 34 a part of eccentric bushing is connected in hexagonal eccentric washer 35
Portion, another part and 1 clearance fit of workbench.34 material of eccentric bushing is Q235, and intensity and plasticity are preferable, 34 end face shape of eccentric bushing
Shape includes inner edge and outer rim, and inner edge is circle, and outer cause circular arc 341 and one or more strings 342 for deviateing inner circle surround, with side
Just eccentric bushing 34 is located in hexagonal eccentric washer 35.Specifically, there are three strings 342 for the setting of 34 outer rim of eccentric bushing, right in this way
The weakening degree of eccentric bushing 34 is small.It is provided with annular gasket 36 between eccentric bushing 34 and bushing 37, rotates 35 band of hexagonal eccentric washer
Dynamic eccentric bushing 34 rotates in workbench 1.
In specific installation process, first 3 structure of eccentric shaft component is connected on workbench, then slide block wheel 2 is mounted on partially
