Abstract

The invention discloses a device for grinding left and right bearing blocks, belonging to the field of machining. The device for grinding the left and right bearing blocks comprises a connecting seat, a clamp body, a tensioning mandrel and a pull rod, wherein the clamp body is connected with the connecting seat; the tensioning mandrel is arranged in the clamp body and is in taper fit with the clamp body; and the pull rod penetrates through the connecting seat and the clamp body and is connected with the tensioning mandrel, and can drive the tensioning mandrel to axially move for applying pressure to the clamp body and realize tensioning. According to the device disclosed by the invention, the positioning precision is high; after parts are clamped for multiple times, the coaxialities of various related sizes can be controlled within a range required by a drawing, so that the quality of a finished product is effectively guaranteed; workpieces are conveniently clamped, and the clamping and correcting time is shortened, so that the working efficiency is greatly improved; and the firmness in clamping is realized, and large cutting amount machining can be met.

Description

Device for the mill processing of Y-axis bearing
Technical field
The present invention relates to a kind of Y-axis bearing processing tool, be especially a kind of dress for the mill processing of Y-axis bearing Put, belong to field of machining.
Background technology
Y-axis bearing is the vital part in bull-dozer central control mechanism, as shown in Figure 1.This part belongs to macropore thin-walled Part, required precision is high, and particularly internal-external circle concentricity requires height, installs with universal fixturing and add on existing general-purpose grinder In man-hour, its clamping correction difficulty, working (machining) efficiency is low, and machining accuracy is poor, and percent defective is high, and quality cannot be guaranteed.
Summary of the invention
The technical problem to be solved is to overcome prior art defect, it is provided that a kind of structure clamping correction is convenient, The device for the mill processing of Y-axis bearing that machining accuracy is high.
In order to solve above-mentioned technical problem, the present invention provide for Y-axis bearing mill processing device, including connect seat, Clamp body, tension mandrel and pull bar, described clamp body connects with being connected seat, and described tension mandrel is located in clamp body, with The tapered cooperation of clamp body, described pull bar is connected with tension mandrel through connection seat, clamp body, can drive tension mandrel Move axially, clamp body pressure is realized tensioner.
As improvement, described clamp body uses short cylindrical matched in clearance with being connected between seat.
As improvement, described tension mandrel and clamp body taper fit tapering are 20 °.
As improvement, described clamp body uses spring steel material to make.
The beneficial effects of the present invention is: (1), positioning precision of the present invention are high, and part is through each relative dimensions of multiple clamping Axiality all can control in the range of drawing requirement, is effectively guaranteed end product quality;Clamping workpiece is convenient, reduces clamping Correction time, it is greatly improved work efficiency rate;Clamping firmly, can meet the processing of big cutting output;(2), clamp body be connected seat Between use short cylindrical matched in clearance, clamp body radially can be finely adjusted, in order to the adjustment to whole device;(3)、 Tension mandrel uses 20 ° of taper fit with clamp body, has enough expanding forces after making tension mandrel move axially to clamp body And positioning precision;(4), clamp body uses spring steel material to make, to ensure that it has preferable consistency and elasticity.
Accompanying drawing explanation
Fig. 1 is Y-axis holder structure schematic diagram;
Fig. 2 is the present invention apparatus structure schematic diagram for the mill processing of Y-axis bearing.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail.
As it is shown in figure 1, the present invention for Y-axis bearing mill processing device, including connect seat 1, clamp body 2, Tension mandrel 3 and pull bar 4.Connect seat 1 and use short tapering seamless connectivity with grinding machine spindle neck, to increase the steady of location Qualitative.
Clamp body 2 connects with being connected seat 1, and clamp body 1 uses short cylindrical matched in clearance with being connected between seat 2, so may be used Clamp body to be made radially fine setting, it is simple to the adjustment to whole device.Clamp body 2 uses spring steel material to make, to protect Demonstrate,prove it and have preferable consistency and elasticity, meet and clamp needs.
Tension mandrel 3 is located in clamp body 2, and tension mandrel 3 and clamp body 2 are in 20 ° of taper fit, to ensure tensioner Mandrel 3 has enough expanding forces and positioning precision to fixture 2 body after moving axially.
Pull bar 4 is connected through connection seat 1, clamp body 2 with tension mandrel 3, and tension mandrel 1 can be driven to connecting seat 1 direction moves axially, and clamp body 2 pressure is realized tensioner.
The use process of the present invention is: first, refines perforate after first clamping with universal fixturing according to Y-axis bearing mill feature 6, and in clamped one time, refine the end face of perforate 6 mouthfuls;Then, Y-axis bearing perforate 6 is enclosed within clamp body 2, Tension mandrel 3 is pulled to move axially to connecting seat 1 direction by pull bar 4, clamp body 2 pressurized outward expansion and Y-axis Bearing is formed and is in close contact, it is achieved being fixedly clamped of Y-axis bearing;Finally, according to drawing, Y-axis bearing is carried out it His ground finish.
Above the detailed description of the invention of the present invention is described, but the present invention is not limited to above description.For ability For the technical staff in territory, any equal amendment to the technical program and replacement are all within the scope of the invention.Cause This, the impartial conversion made without departing from the spirit and scope of the invention and amendment, all should contain in the scope of the present invention In.
