A kind of adjustable axial part weld jig
Technical field
The utility model relates to a kind of frock clamp, is specifically related to a kind of adjustable axial part weld jig.
Background technology
In production practices, sometimes need two minor axises to be welded to each other into vertically an overall major axis, in order to ensure precision and the axiality of welding process, general adopt weld jig that two minor axises are fixing after weld again.Chinese patent ZL201020055204.2 discloses a kind of welding clamp apparatus for shaft components, by the guide holder of band oil groove, the axis of guide, fixed clamping device and movable clamping device composition, fixed clamping device and movable clamping device are by between installation, upper vee-block, lower vee-block, rectangular tube and turning cylinder composition, the bottom surface of lower vee-block is welded on the upper surface of rectangular tube, mounting bracket is welded on the side of lower vee-block, turning cylinder is screwed on mounting bracket, its lower end is flexibly connected with upper vee-block, vee-block is made to be positioned at directly over lower vee-block, and the V-shaped groove of the V-shaped groove of upper vee-block and lower vee-block is vertically opposite.Although the program makes two clamping devices horizontally slip the clamping of different length axial workpiece by slip rectangular tube, rectangular tube can stretch out guide holder, makes this fixture need take more axial space, if possibly cannot normally use in narrow space; And there is no retention mechanism after having slided, may there is secondary and slide in rectangular tube, if two minor axises can be caused to be separated in the slip of welding process generation secondary, welding is interrupted, could continue welding, and then reduce welding efficiency after need again adjusting; In addition, mounting bracket is inverted L-shaped, and namely this mounting bracket only has one side to weld with rectangular tube, easily occurs the situation of distortion, causes restraint location to offset, finally cause the axiality of two minor axises to decline, can produce a certain amount of substandard products.
Utility model content
The purpose of this utility model is: provide a kind of adjustable axial part weld jig, and the axial space temporary existed to solve traditional welding fixture greatly, easily occurs that secondary slides, precision reduces, yielding problem.
The utility model is achieved by the following technical solution:
A kind of adjustable axial part weld jig, comprise base, be connected with bearing in the middle part of base, bearing two ends are provided with support, are connected with nut in the middle part of cantilever tip, stud is provided with in nut, stud is passed down through support and its end is connected with the pressing plate matched with bearing, and described support is door shape, and support both sides are connected with sliding sleeve, bearing both sides are provided with axial arranged slide rail, and sliding sleeve is socketed on slide rail.
Described sliding sleeve is provided with caging bolt, and this caging bolt passes sliding sleeve and fits with slide rail upper surface.
Distance between pushing up in described rail tips and sliding sleeve is 1 ~ 3mm.
Described pressing plate and bearing opposite face are the V-arrangement of indent.
The cross section of described slide rail is trapezoidal.
The beneficial effects of the utility model are:
Compared with prior art, the adjustable axial part weld jig that the utility model provides, becomes door shape by support Design, avoids it to occur the situation of distortion, and then increases service life and ensure that the axiality of welding shaft part; And the both sides of support are provided with slide rail, support is socketed in the slide rail top on base by sliding sleeve, realize retention mechanism slide axially and can not axial occupation space, there is the feature of small and exquisite practicality; On sliding sleeve, be provided with caging bolt simultaneously, can be fixed on slide rail by support, secondary slides and causes weld failure to prevent support from occurring.

Fig. 2 is left view of the present utility model;
In figure: 1-bearing, 2-slide rail, 3-base, 4-caging bolt, 5-pressing plate, 6-support, 7-stud, 8-handle, 9-nut, 10-sliding sleeve.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but described in required protection domain is not limited to;
As shown in Figure 1, 2, the adjustable axial part weld jig that the utility model provides, comprises base 3, is connected with bearing 1 in the middle part of base 3, bearing 1 two ends are provided with support 6, support 6 top middle portion is connected with nut 9, is provided with stud 7 in nut 9, and stud 7 is passed down through support 6 and its end is connected with the pressing plate 5 matched with bearing 1, described support 6 is door shape, support 6 both sides are connected with sliding sleeve 10, and bearing 1 both sides are provided with axial arranged slide rail 2, and sliding sleeve 10 is socketed on slide rail 2.
The secondary fixing after-poppet 6 in order to avoid axial workpiece slides, and described sliding sleeve 10 is provided with caging bolt 4, and this caging bolt 4 passes sliding sleeve 10 and fits with slide rail 2 upper surface.
In order to reduce the frictional force of slip, the distance between pushing up in described slide rail 2 top and sliding sleeve 10 is 1 ~ 3mm.
In order to meet the user demand of the axial workpiece of different-diameter, described pressing plate 5 and bearing 1 opposite face are the V-arrangement of indent.
For the ease of the dismounting of support 6, the cross section of described slide rail 2 is trapezoidal.
During use, first will two sections of minor axises of welding be needed to be placed on the bearing 1 of V-arrangement, and ensure that two minor axises contact, the support 6 of the door shape respectively above sliding support 1, two supports 6 are made to be positioned at both sides, welding position, then caging bolt 4 is screwed, realize the locking of support 6, secondary slides to prevent it from occurring, then rotating handles 8 and then drive stud 7 rotate in nut 9, stud 7 backspin under the effect of nut 9, the pressing plate 5 promoting V-arrangement moves down and jointly completes fixing to clamp of axial workpiece with bearing 1, can start to weld.
