The utility model relates to an adjustable clamping tool which comprises a base seat, fixing blocks, a pressing block and an adjusting rod, wherein a plurality of mounting holes are arranged at both ends of the base seat, and a support which is perpendicular to the direction of the base seat is arranged in the middle of the base seat. A plurality of fixing holes are arranged inside the support rack of the base seat. The fixing blocks are arranged inside the support rack and fixed in the fixing holes of the base seat through screws. The number of the fixing blocks is two, and a V-shaped groove is formed between the two fixing blocks. The adjusting rod which is perpendicular to the base seat is arranged in the middle of the support rack. The bottom end of the adjusting rod is connected with the pressing block, and the top end of the adjusting rod stretches out of the support rack. The pressing block is arranged between the two fixing blocks, two side surfaces of the pressing blocks are inclined surfaces, and the inclination of the pressing block is the same with that of the two fixing blocks. The adjustable clamping tool is adopted so as to not only expand machining scope of workpieces but also improve machining precision and efficiency of the workpieces.

Description

A kind of alignment jig

Technical field

The utility model relates to a kind of machining servicing unit, during especially a kind of processing slim axle, avoids the diameter of axle to beating, and guarantees the alignment jig of machining accuracy.

Background technology

During machining, in order to guarantee the machining accuracy of each processing parts, often all can adopt various stationary fixtures.Especially when some elongated axial workpieces of processing, if do not adopt some anchor clamps to avoid adding man-hour, axle generation circular runout will produce a large amount of workpiece of scrapping, and has seriously reduced manufacturing schedule and working (machining) efficiency.

For this reason, the insider is to adopt two or more circular geometrical clamps to fix workpiece, as shown in Figure 1 when this class thin and long shafts part of processing usually.This circle geometrical clamp is comprised of an annular fixed block 101 and a depression bar 102 that passes fixed block 101 usually, and the bottom center of described fixed block 101 is extended with a fixture block 103 downwards, and by this fixture block 103 fixed block 101 is fixed on workbench.During use, workpiece 104 is placed in the fixed block 101, and by depression bar 102 workpiece pressings 104, again with whole device together with workpiece 104, be stuck on the workbench by fixture block 103 in the lump, workpiece 104 is processed.But, when adopting this anchor clamps processing thin and long shafts part, can not firmly part be fixed on the workbench, add deviation very easily occurs man-hour; And, only push down workpiece by depression bar, at the workpiece of taking, perhaps workpiece is turned around to add man-hour, also can be offset between anchor clamps and the workpiece, machining accuracy is very low; In addition, for some axial workpieces greater than the fixed block internal diameter, just can not process.

The utility model content

The utility model purpose is that a kind of raising Workpiece Machining Accuracy is provided in order to overcome the deficiencies in the prior art, enlarges the alignment jig of the workpiece range of work.

For achieving the above object, the technical solution adopted in the utility model is: a kind of alignment jig comprises base, fixed block, briquetting, adjusting rod; The two ends of described base have a plurality of installing holes, and the middle part of base is provided with a bracing frame in the direction perpendicular to base; On the described base, be positioned at the inside of bracing frame, be provided with a plurality of fixing holes; Described fixed block is positioned at the inside of bracing frame, and is fixed by screws in the fixing hole of base; Described fixed block is two, and forms a v-depression between two fixed blocks; In the heart, be provided with one perpendicular to the adjusting rod of base in the support frame as described above; The bottom of described adjusting rod connects briquetting, and bracing frame is stretched out on its top; Described briquetting is between two fixed blocks, and the two sides of briquetting are the inclined-plane, the gradient phase order of its gradient and fixed block with.

Preferably, support frame as described above is by two gripper shoes, is positioned at the gripper shoe top with one and forms with two vertical fixing crossbeams of gripper shoe; Described adjusting rod is vertically fixed on the center of crossbeam.

Preferably, the described adjusting rod end that stretches out crossbeam is provided with an annular handle.

Because the utilization of technique scheme, the utility model compared with prior art has following advantages:

A kind of alignment jig of the utility model scheme, it is by can be at two fixed blocks and the briquetting of bracing frame internal regulation size, be fixed on firmly workpiece on the base, and by the installing hole on the base base is stabilized on the workbench together with workpiece, not only enlarged the range of work of workpiece, and Effective Raise the machining accuracy of workpiece, especially for the processing of thin and long shafts part, adopt two or more alignment jigs of the present utility model, just can avoid workpiece generation circular runout in the process, guarantee the machining accuracy of such part, Effective Raise production efficiency greatly reduces the scrappage that workpiece is processed.

Description of drawings

Below in conjunction with accompanying drawing technical solutions of the utility model are described further:

Accompanying drawing 1 is the structural representation of the circular geometrical clamp of prior art;

Accompanying drawing 2 is the structural representation of alignment jig of the present utility model;

Wherein: 1, base; 2, gripper shoe; 3, crossbeam; 4, fixed block; 5, briquetting; 6, screw; 7, adjusting rod; 8, handle; 9, fixing hole; 10, installing hole; 11, workpiece.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Accompanying drawing 2 is a kind of alignment jig described in the utility model, comprises base 1, fixed block 4, briquetting 5, adjusting rod 7; The two ends of described base 1 have a plurality of installing holes 10; The middle part of described base 1 is provided with one by two gripper shoes 2 on the direction perpendicular to base 1, with the bracing frame that is positioned at gripper shoe 2 tops and forms with two gripper shoes, the 2 vertical crossbeams of fixing 3; On the described base 1, be positioned at the inside of bracing frame, be provided with a plurality of fixing holes 9; Described fixed block 4 is positioned at the inside of bracing frame, and is fixed on by screw 6 in the fixing hole 9 of base 1; Described fixed block 4 is two, and forms a v-depression between two fixed blocks 4; In the heart, be provided with one perpendicular to the adjusting rod 7 of base 1 in the described crossbeam 3; The bottom of described adjusting rod 7 connects briquetting 5, and crossbeam 3 is stretched out on its top; The end that described adjusting rod 7 stretches out crossbeam 3 is provided with an annular handle 8, has made things convenient for carrying and the movement of anchor clamps; Described briquetting 5 is between two fixed blocks 4, and the two sides of briquetting 5 are the inclined-plane, and its gradient is identical with the gradient of fixed block 4.

During use, workpiece 11 is placed between two fixed blocks 4, regulate the position of fixed block 4 by screw 6 and fixing hole 9, and tighten screw 6, again by adjusting rod 7 control briquettings 5 workpiece pressings 11 on the crossbeam 3, at last whole device is placed on the workbench, and be fixedly connected with workbench by installing hole 10, skew or slip had both been guaranteed not occur between workpiece and the anchor clamps, also guaranteed the steadiness between anchor clamps and the workbench, Effective Raise machining accuracy and the working (machining) efficiency of workpiece, reduced the scrappage of workpiece.
