Abstract

The utility model discloses a special fixture used for a rescue engineering vehicle transitional connecting plate. The special fixture comprises a circular positioning plate, wherein positioning bosses are arranged on the positioning plate, key grooves are formed in the positioning plate, key groove bolts capable of being fixed on a lathe face plate are installed in the key grooves, and fixing pressing plates are installed on the key groove bolts. Stud inserting holes are formed in the positioning bosses, studs are installed in the stud inserting holes, and the studs are provided with fixing pressing plates capable of pressing the transitional connecting plate. The special fixture has the advantages of not only being simple in structure and convenient to machine, but also being ingenious in design, safe, reliable, and rapid in clamping and positioning, saving materials, reducing manufacturing cost of the special fixture, improving working efficiency, and the like.

Description

A kind of special fixture for the emergency engineering vehicle transition connecting disc
Technical field
The utility model relates to a kind of special fixture, particularly a kind of special fixture for the emergency engineering vehicle transition connecting disc.
Background technology
at present, emergency engineering vehicle is a kind of disaster unit, this car can be used for various landform, particularly earthquake relief work and speedily carry out rescue work aspect play a positive role, transition connecting disc is a strength member on emergency engineering vehicle, but because of this accessory size larger, material is softer, be the circular thin-wall structure, owing to there is no special fixture, the operator can only process with four paws clamping part, but because this accessory size is larger, wall is thin, during with the four paws clamping, part is radial force, chucking power can not be excessive, actual processing is very difficult, after completion, not only deflection is large for part, size also is difficult for guaranteeing, quality and the assembling performance of part have been had a strong impact on, and production efficiency is low, economy to company has caused loss, so prior art is still perfect not.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, practical, draw materials conveniently, the clamping location is quick, a kind of special fixture for the emergency engineering vehicle transition connecting disc that can guarantee the transition connecting disc machining accuracy, to overcome the deficiencies in the prior art.
The utility model is constructed as follows: a kind of special fixture for processing emergency engineering vehicle transition connecting disc, comprise circular positioning disk, be provided with positioning boss on positioning disk, be provided with keyway on positioning disk, the keyway bolt that can be fixed on the lathe floral disc is installed in keyway, on the keyway bolt, fixation clip is installed; Be provided with the double-screw bolt jack on positioning boss, in the double-screw bolt jack, studs be installed, the fixation clip that can compress transition connecting disc is installed on studs.
Be provided with four keyways and four double-screw bolt jacks on positioning disk.
Owing to having adopted technique scheme, at first positioning disk is fixed on the floral disc of lathe with 4 keyway bolts and fixation clip, again part is contained on the positioning boss of positioning disk, hole in piece part and end face coordinate with positioning boss place's cylindrical and the shaft shoulder, then with 4 studs and fixation clip, part end face are compressed; Compared with prior art, the utility model not only has advantage simple in structure, easy to process, and design ingenious, safe and reliable, clamping location quick, saved material and reduced the cost of manufacture of this frock, the advantage such as increase work efficiency.

Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1;
Description of reference numerals: 1-positioning disk, 2-positioning boss, 3-keyway, 4-keyway bolt, 5-fixation clip, 6-double-screw bolt jack, 7-studs.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Enforcement of the present utility model: a kind of special fixture for the emergency engineering vehicle transition connecting disc, comprise circular positioning disk 1, be provided with positioning boss 2 on positioning disk 1, be provided with keyway 3 on positioning disk 1, the keyway bolt 4 that can be fixed on the lathe floral disc is installed in keyway 3, fixation clip 5 is installed on keyway bolt 4; Be provided with double-screw bolt jack 6 on positioning boss 2, studs 7 is installed in double-screw bolt jack 6, the fixation clip 5 that can compress transition connecting disc is installed on studs 7.
Be provided with four keyways 3 and four double-screw bolt jacks 6 on positioning disk 1.
during work, at first 4 keyway bolts 4 of positioning disk 1 use and pressing plate are fixed 5 on the floral disc of lathe, again part is contained on the positioning boss 2 of positioning disk 1, hole in piece part and end face coordinate with positioning boss 2 place's cylindricals and the shaft shoulder, with 4 studs 7 and fixation clip 5, part end face is compressed again, this special fixture changes part into present axial compression by original radially clamping, so come clamping parts with it, the machining deformation amount of part reduces greatly, not only the clamping of part is reliable, stopped situation about dropping fully, and improved the efficient of parts fixation and correction, saved the cost of manufacture of material and this frock of minimizing, be worthy to be popularized.
The utility model is applicable, and to be clamped in size larger, and material is softer, is the part of circular thin-wall structure.
