Abstract

The utility model discloses a universal adjustable key slot aligner. The universal adjustable key slot aligner is characterized in that the universal adjustable key slot aligner comprises an adjustable part and an aligning element; the adjustable part comprises a sliding base and a slider, the sliding base is connected with a worktable through keys, a T-shaped socket is vertically machined on the sliding base, the slider is arranged in the T-shaped socket, and is fixed by set screws, and the aligning element is fixed on the slider by a screw. When the universal adjustable key slot aligner needs to be used, by means of the sliding base, the universal adjustable key slot aligner is firstly moved to be beside a workpiece to be machined, the aligning element is then utilized to align the workpiece, the slider is then locked, and finally, key slots are machined on the workpiece. The adjustable part in the universal adjustable key slot aligner is a universal part, and according to different types of workpieces, only the aligning element needs to be replaced. The adjustment of the universal adjustable key slot aligner and the replacement of the aligning element are highly convenient and efficient, and the universal adjustable key slot aligner not only meets the requirement of machining multiple varieties in different batches, but also greatly increases the precision of alignment and working efficiency.

Description

A kind of keyway centralising device of Universal adjustable

Technical field

The utility model relates to the jig field, relates in particular to a kind of keyway centralising device of Universal adjustable.

Background technology

Mechanical transmissioning piece has much endoporus and keyway is had status requirement each other, as the external tooth axle sleeve requirement keyway of gear coupling and a tooth top centering of external tooth, requires a screw centering of keyway and end face as half a coupler.If the specification of this class workpiece is wide in variety, the batch is little, it is just unrealistic to do special fixture, therefore adopts the method for line, school line to guarantee mostly.But by artificial line school line, not only operating efficiency is low, cost is high, and accuracy of alignment also is difficult to guarantee.

Summary of the invention

Problem to be solved in the utility model provides a kind of keyway centralising device of Universal adjustable, and it is very convenient quick that centring element is adjusted and changed to this device, has not only satisfied the different processing requests in batches of many kinds, and accuracy of alignment and operating efficiency also improve greatly.

The keyway centralising device of a kind of Universal adjustable of the utility model is characterized in that: it is made up of tunable component and centring element; Tunable component comprises sliding bottom, slide block, and sliding bottom links to each other with workbench by key, vertically is processed with the T-shape groove on the sliding bottom, and slide block is placed in the T-shape groove, and fixes by holding screw, and centring element is fixed on the slide block by screw.

When using this novel Universal adjustable keyway centralising device, elder generation moves to device by the workpiece that needs processing by sliding bottom, by centring element workpiece is carried out centering again, locks slide block then, at last workpiece is carried out the processing of keyway.Tunable component wherein is universal component, and dissimilar according to workpiece are as long as change centring element.

Therefore, this device is universal fixturing, can be fit to the groove processing of different workpieces, has both guaranteed accuracy of alignment, has improved operating efficiency, also can not raise the cost.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the structural representation one of the adjustable keyway centralising device of this novel universal;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the structural representation two of the groove centralising device of the adjustable key of this novel universal;

Fig. 4 is the vertical view of Fig. 3.

The specific embodiment

From Fig. 1, Fig. 2, Fig. 3, Fig. 4 as can be known, this novel a kind of Universal adjustable keyway centralising device, it is made up of tunable component and centring element.

Wherein, tunable component comprises sliding bottom 2, slide block 5, and sliding bottom 2 links to each other with workbench 1 by key, vertically be processed with the T-shape groove on the sliding bottom 2, slide block 5 is placed in the T-shape groove, and fixing by holding screw 6, and centring element is fixed on the slide block 5 by screw 4.Wherein, sliding bottom 2 can be free to slide along the keyway horizontal direction in the keyway the inside of workbench 1 by the key of bottom; Slide block 5 can move up and down in the T type groove on the sliding bottom 2 regulates height, to be fit to the workpiece of differing heights.

Fig. 1, Fig. 2 are the structural representation one of this new device, it is applicable to the centering of tooth and keyway: centring element is tooth locating piece 3, and tooth locating piece 3 is " L " type, and the one end is fixed on the slide block 5 by screw 4, other end head is tooth bar, and the tooth on it is meshed with external tooth workpiece 9.

When using the device of tooth and keyway centering, earlier external tooth workpiece 9 is placed on that (external tooth workpiece 9 is felt relieved on the workbench 1 on broaching machine, external tooth workpiece 9 can only rotate), place sliding bottom 2 on the workbench 1 again and to move to external tooth workpiece 9 other, the slide block 5 that then will be positioned in the sliding bottom 2 "T"-shaped grooves moves up and down, make a tooth of tooth locating piece 3 centering external tooth workpiece 9, then fastening holding screw 6.At this moment, compress external tooth workpiece 9, can process keyway.In this device, the teeth groove that tooth locating piece 3 is equivalent to tooth bar is stuck on the tooth two sides of external tooth, thereby realizes keyway centering.When tooth locating piece 3 is changed different moduluses, can realize the external tooth axle sleeve keyway of different size size and the centering of tooth top.

Fig. 3, Fig. 4 are the structural representation two of this new device, it is applicable to the centering of screw and keyway: centring element comprises finger setting piece 7 and alignment pin 8, finger setting piece 7 is " L " type, the one end is fixed on the slide block 5 by screw 4, other end head is " V " type piece, and " V " type piece is stuck on the alignment pin 8 that is arranged on half a coupler workpiece 10 holes.

When using the centralising device of screw and keyway, earlier half a coupler workpiece 10 is placed on that (half a coupler workpiece 10 is felt relieved on the workbench 1 on broaching machine, half a coupler workpiece 10 can only rotate), place sliding bottom 2 on the workbench 1 again and to move to half a coupler workpiece 10 other, the slide block 5 that then will be positioned in the sliding bottom 2 "T"-shaped grooves moves up and down, make " V " type piece on the finger setting piece 7 block the alignment pin 8 that is arranged on half a coupler workpiece 10 holes, then fastening holding screw 6.At this moment, compress half a coupler workpiece 10, can process keyway.In this device, the teeth groove that finger setting piece 7 is equivalent to tooth bar is stuck in realization keyway centering on the alignment pin 8.When alignment pin 8 is changed different diameters, thereby namely realize the half a coupler keyway of different size and the centering of screw.

This novel centralising device is under the prerequisite that workpiece has been felt relieved, makes workpiece turn to suitable position, and workpiece pressing is processed keyway again, and whole device is opened with regard to removable behind Work-sheet pressing, just needs fastening holding screw during first adjustment.
