Abstract

The utility model relates to a Jig of double sided milling machine processing high wearing resistant steel S pipe constituted by a big head jig and a small head jig, which are independent from each other but are required to be cooperated with each other. The big head jig and the small head jig are disposed on the surface of the working platform of the milling machine. The big head jig is constituted by a fixed support 1, a moving clamp2, a middle hinge 3, a screw jaw 4, and an adjusting screw 5. A through hole has the same shape as a big head of an S pipe blank can be formed, when the fixed support 1 and the moving clamp 2 are closed. The small head jig, just like the big head jig, is constituted by a fixed support 1, a moving clamp2, a middle hinge 3, a screw jaw 4, and an adjusting screw 5. A through hole has the same shape as a small head of an S pipe blank can be formed, when the fixed support 1 and the moving clamp 2 are closed. The utility model is advantageous in that the end surface of the S pipe, the excircle and the spline bore can be processed only by using the double sided milling machine, thereby the equipment investment can be reduced; the processing of the end surface, the excircle, and the spline bore of the S pipe blank can be finished once on the jig and the milling machine, thereby the adjusting time can be reduced, the production efficiency can be improved, and the processing quality of parts can be guaranteed.

Description

A kind of anchor clamps of processing high Development of Wear Resistant Steel S pipe with double sides milling machine

Technical field

The utility model belongs to technical field of tooling clamps, relates in particular to a kind of anchor clamps of processing high Development of Wear Resistant Steel S pipe with double sides milling machine.

Technical background

The S pipe is a kind of vitals that concrete pump is used for distributing delivering concrete, as shown in Figure 1, generally the charging aperture with the S pipe is called big end 1, discharging opening is a small end 2, on big end, a splined shaft endoporus 3 is arranged, one splined shaft is installed in the hole, the S tubular axis connects with splined shaft with swing arm, swing arm is under the effect of oil cylinder, drive the S pipe around the axis reciprocally swinging, therefore S is managed the end face of the big end 1 of blank, cylindrical, the end face of small end 2, cylindrical and splined shaft endoporus 3 will carry out machining, general processing method is to adopt milling machine processing end face at present, adopt the lathe turning cylindrical, adopt boring machine to bore endoporus, this processing method operation is various, the process equipment investment is big, is difficult to guarantee following assembly precision requirement simultaneously: splined shaft and S pipe small end discharging opening outer circles must not be greater than 0.07mm; Splined shaft is no more than ± 0.2mm with the centre-to-centre spacing error of big endfeed mouth; The axial line of splined shaft is no more than 0.1mm with the vertical error on wear ring plane, big endfeed mouth place.Because S pipe outer shape is special, adopts high Development of Wear Resistant Steel manufacturing, accuracy of form and position requirement is also higher in addition, thereby the time of clamping and correction is long, mismachining tolerance is bigger, not only makes troubles to manufacturing procedure, also can influence processing progress and operating efficiency.

Summary of the invention:

Problem to be solved in the utility model provides a kind of simple in structure, and the convenient anchor clamps that utilize the disposable processing S pipe of double sides milling machine blank end face, cylindrical and endoporus have accurately not only guaranteed the crudy of part, and reduced processing cost.

A kind of anchor clamps of processing high Development of Wear Resistant Steel S pipe with double sides milling machine of the present invention, form by separate existence and the big fixture head that must be used and microcephaly's anchor clamps, they are installed on the work top of milling machine, wherein big fixture head (Fig. 2) is by fixed mount 1, adjustable clamp 2, middle hinge 3, spiral shell button 4 and adjust screw 5 and forms, and fixed mount 1 and adjustable clamp 2 form when closed and S manages the consistent through hole of blank major part profile.Little fixture head (Fig. 3) is the same with big fixture head, and also by fixed mount 1, adjustable clamp 2, middle hinge 3, spiral shell button 4 with adjust screw 5 and forms, fixed mount 1 and adjustable clamp 2 form when closed and S manages the consistent through hole of blank microcephaly's profile.The fixed mount 1 of two anchor clamps is fixed on the work top of milling machine, and adjustable clamp 2 can cut with scissors 3 around the centre and rotate, and by 4 lockings of spiral shell button, adjusts screw 5 and can finely tune.Add man-hour, loosen spiral shell button 4 and open adjustable clamp 2, the S pipe is put into anchor clamps, the adjustable clamp 2 that closes, locking screw button 4, carry out centering by adjusting 5 pairs of S pipes of screw blank, utilize double sides milling machine then, only need by changing cutter, disposable processing S pipe end face, cylindrical and endoporus, guarantee machining accuracy, reduced man-hour and equipment investment.

Advantage of the present utility model is that it only need utilize double sides milling machine, just can process S pipe end face, cylindrical and spline endoporus, has reduced equipment investment; S pipe blank is once finished the process of end face, cylindrical and spline endoporus on anchor clamps and milling machine simultaneously, has reduced the adjustment time, has improved production efficiency, has guaranteed the crudy of part simultaneously.

The specific embodiment

Further understand the present invention below by specific embodiment.

Big fixture head (Fig. 2) and little fixture head (Fig. 3) are installed on the work top of milling machine, and wherein big fixture head (Fig. 2) is made up of fixed mount 1, adjustable clamp 2, middle hinge 3, spiral shell button 4 and adjustment screw 5.Little fixture head (Fig. 3) is the same with big fixture head, also is made up of fixed mount 1, adjustable clamp 2, middle hinge 3, spiral shell button 4 and adjustment screw 5.The fixed mount 1 of two anchor clamps is fixed on the work top of milling machine, and adjustable clamp 2 can cut with scissors 3 around the centre and rotate, and by 4 lockings of spiral shell button, adjusts screw 5 and can finely tune.Add man-hour, loosen spiral shell button 4 and open adjustable clamp 2, the S pipe is put into anchor clamps, the adjustable clamp 2 that closes, locking screw button 4 is managed the blank centering by adjusting screw 5 with S, utilizes double sides milling machine then, by changing cutter, disposable processing S pipe end face, cylindrical and endoporus.
