Abstract

The utility model discloses a universal slider which comprises a sliding plate working platform, wherein steel balls are configured on four feet of the sliding plate working platform, and the steel balls are arranged in hoops and can rotate freely. The sliding plate working platform is composed of a working flat plate, upper sliding plates, lower sliding plates, the steel balls, baskets, limiting blocks and a base plate, wherein the upper sliding plates are arranged on the lower end face of the working flat plate and connected with the working flat plate through inside hexagonal bolts, the baskets are connected with the upper sliding plates through the limiting blocks, the limiting blocks are arranged in the baskets, and the limiting blocks ensure that the baskets are placed in the center height positions of the steel balls and limit and fix the positions of the steel balls. The lower sliding plates are arranged on the base plate and matched with the upper sliding plates. The steel balls which are configured on the four feet of the sliding plate working platform can rotate freely in the hoops, therefore, workpiece sliding resistance when drilling automatic alignment is conducted is eliminated, a drill bit is automatically aligned to the most central position of a hole to be drilled, and machining precision is improved.

Description

Universal slider

Technical field

The utility model relates to the rig technical field, specifically belongs to universal slider.

Background technology

In mechanical processing technique, the boring on plane is ubiquitous, is modal manufacturing procedure in the common processes, all is like this at ferrous metal or non-ferrous metal no matter.And it is investigated and under the drilling technique mass production state, all adopt template boring at present by card that it is the most general namely utilizing existing bushing plate boring method, at a small amount of or the next use machining center of single-piece production state or line bore mode.The shortcoming of bushing plate boring is that each part all needs to be equipped with a bushing plate, because bushing plate covers on the workpiece, the real-time machining state in hole is difficult to observe during boring, need wait until that boring finishes, remove could find that boring procedure may occur behind the bushing plate unusually.Therefore, be difficult to hold the surface quality of workpiece, hole by machining center that then efficient is low, cost is high, by line hole then that precision is difficult to guarantee and efficient low excessively be apparent shortcoming.In the existing processing technology mode, the point of employing hole and then a bore process are arranged also, but since when the boring of some hole site workpiece big at the resistance that workbench moves, the centering of drill bit and some hole site is fully with operative employee's technology and sensation.So cause the randomness of bore error big, the decentralization of error amount is big, to get over for a long time when the hole, plane, its quality is instability especially.

The utility model content

The purpose of this utility model has provided universal slider, the deficiencies in the prior art have been overcome, simplicity of design, rational in infrastructure, steel ball freely rolling in anchor ear by the configuration of slide plate workbench four pin, workpiece resistance to sliding when having eliminated the boring automatic capturing makes drill bit automatically on the position, bosom of putting the hole, has improved machining accuracy.

The technical solution adopted in the utility model is as follows:

Universal slider, comprise the slide plate workbench, described slide plate workbench four pin dispose steel ball, steel ball is arranged at freely rolling in the anchor ear, described slide plate workbench is made up of working plate, upper slide, lower skateboard, steel ball, the gaily decorated basket, limited block, base plate, upper slide is arranged at the working plate lower surface, be connected by hexagon socket head cap screw with working plate, the gaily decorated basket is connected with upper slide by limited block, limited block is arranged in the gaily decorated basket, limited block has guaranteed the centre-height position of the gaily decorated basket at steel ball, restriction and stationary balls position.Lower skateboard is arranged on the base plate and matches with upper slide.

Described limited block and upper slide are connected and fixed by interior hexagonal dormant bolt.

Compared with the prior art, the beneficial effects of the utility model are as follows:

The utility model is by steel ball freely the rolling in anchor ear of slide plate workbench four pin configuration, workpiece resistance to sliding when having eliminated the boring automatic capturing, make drill bit automatically on the position, bosom of putting the hole, improved machining accuracy, improve boring pitch-row precision 90%, the error amount decentralization also drops in 0.1 scope from 0.7.Apparently higher than bushing plate, bushing plate is processed work of every processing all will dismantle bushing plate one time with the efficient of universal slider boring, and the slide plate workbench then need not unloading process, and efficient obviously improves.The line drilling efficiency is low, precision is low, and the machining center then cost height of holing adopts then precision height and processing cost is low of universal slider.

Description of drawings

Fig. 1 is structural representation of the present utility model;

The structural representation that Fig. 2 overlooks for the utility model.

The specific embodiment

Referring to accompanying drawing, universal slider, comprise the slide plate workbench, slide plate workbench four pin dispose steel ball 5, steel ball 5 is arranged at freely rolling in the anchor ear 8, the slide plate workbench is made up of working plate 1, upper slide 3, lower skateboard 9, steel ball 5, the gaily decorated basket 4, limited block 6, base plate 10, upper slide 3 is arranged at working plate 1 lower surface, be connected by hexagon socket head cap screw 2 with working plate 1, the gaily decorated basket 4 is connected with upper slide 3 by limited block 6, limited block 6 is arranged in the gaily decorated basket 4, and limited block 6 has guaranteed the centre-height position of the gaily decorated basket 4 at steel ball 5, restriction and stationary balls 5 positions.Limited block 6 is connected and fixed by interior hexagonal dormant bolt 7 with upper slide 3, and lower skateboard 9 is arranged on the base plate 10 and matches with upper slide 3.Before the boring, the workpiece of waiting to hole is by pressing plate mould point hole or numerical control point hole.Universal slider is placed on the Drilling machines bench, workpiece is put on the working plate plane of universal slider, the workpiece taper hole is moved in the drill bit scope, the axial force that the drill bit feeding produces makes the slide plate generation along the power of in-plane, because rolling steel balls is at the rolling action between slide plate up and down, dull and stereotyped minimum along the resistance of in-plane, drill bit can be looked for to the optimum position of impression automatically and begin drilling.

Claims (2)

1. universal slider, comprise the slide plate workbench, it is characterized in that: described slide plate workbench four pin dispose steel ball, steel ball is arranged in the anchor ear, and described slide plate workbench is made up of working plate, upper slide, lower skateboard, steel ball, the gaily decorated basket, limited block, base plate, and upper slide is arranged at the working plate lower surface, be connected by hexagon socket head cap screw with working plate, the gaily decorated basket is connected with upper slide by limited block, and limited block is arranged in the gaily decorated basket, and lower skateboard is arranged on the base plate and matches with upper slide.
