Abstract
A positioning and compressing device for an automobile crane jib body comprises a bottom plate, a rear vertical plate, positioning sleeves, a vertical plate, compressing threaded rods, locking nuts, trapezoid-groove bolts and a trapezoid-groove working table. The bottom plate, the rear vertical plate and the vertical plate are welded to be an overall structure and form a left support and a right support which are symmetric, the positioning sleeves are welded to the rear vertical plate, and the four compressing threaded rods provided with the locking nuts are screwed in the positioning sleeve of the left support and the positioning sleeve of the right support respectively; a plurality of trapezoid-groove bolt fixing holes are formed in the trapezoid-groove working table, the left support and the right support are fixed in the corresponding trapezoid-groove bolt fixing holes in the trapezoid-groove working table through the trapezoid-groove bolts according to the width of the crane jib body, and threads corresponding to the compressing threaded rods are arranged in the positioning sleeves. The positioning and compressing device has the advantages of being simple in structure, low in cost, high in strength, convenient to disassemble and good in machining accuracy, and the width requirements of different crane jib bodies can be met by freely changing the interval of the positioning and compressing device.
Description
technical field:
The utility model belongs to autocrane and manufactures field, relates in particular to a kind of positioning compression device of automobile crane horn body.
background technology:
Along with the fast development of economic construction, the capital construction dynamics of China is also strengthening gradually, and the construction scale of the infrastructure such as traffic route, airport, water conservancy and hydropower, urban construction is also increasing, and market also increases the demand of autocrane thereupon.The competition in autocrane market is also more and more fierce, the requirement of manufacturing process is also improving constantly, the machining accuracy of automobile crane horn body is a very important key during autocrane is manufactured, in order to improve the machining accuracy of gib arm of crane body, we have designed a kind of positioning compression device of automobile crane horn body, process various crane arm.
summary of the invention:
The purpose of this utility model is in order to guarantee the precision of the processing of automobile crane horn body, and a kind of positioning compression device of automobile crane horn body is provided.
The technical solution of the utility model is to implement like this: a kind of positioning compression device of automobile crane horn body, comprise that base plate, back vertical plate, positioning sleeve, riser, clamping screw, locking nut, dovetail groove bolt and dovetail groove workbench form, the structure that base plate, back vertical plate, riser are welded as a whole, form symmetrical left socle and right support, on back vertical plate, be welded with positioning sleeve, be provided with in the clamping screw difference precession left socle of locking locknut and the positioning sleeve of right support; Dovetail groove workbench is provided with a plurality of dovetail groove bolt fixing holes, and according to the width of gib arm of crane body, left socle and right support are bolted in the corresponding dovetail groove bolt of dovetail groove workbench fixing hole by dovetail groove.
In described positioning sleeve, be provided with the screw thread corresponding with clamping screw.
The utility model positioning compression device has simple in structure, can freely change the width that its spacing meets dissimilar arm body, and cost is low, and intensity is high, convenient disassembly, the good advantage of processing accuracy.
accompanying drawing explanation:
Fig. 1 is the front view of the utility model structure;
Fig. 2 is the left view of the utility model structure;
In figure: 1. base plate, 2. back vertical plate, 3. positioning sleeve, 4. riser, 5. clamping screw, 6. locking nut, 7. dovetail groove bolt, 8. dovetail groove workbench.
the specific embodiment:
As Fig. 1, as shown in Figure 2, a kind of positioning compression device of automobile crane horn body, comprise base plate 1, back vertical plate 2, positioning sleeve 3, riser 4, clamping screw 5, locking nut 6, dovetail groove bolt 7, dovetail groove workbench 8, it is characterized in that: the structure that base plate 1, back vertical plate 2, riser 4 are welded as a whole, form symmetrical left socle and right support, on back vertical plate 2, being welded with 3, four of positioning sleeves is provided with in the clamping screw 7 difference precession left socles of locking locknut 6 and the fixed cover 3 of right support; Dovetail groove workbench 8 is provided with a plurality of dovetail groove bolt 7 fixing holes, and according to the width of gib arm of crane body, left socle and right support are fixed on corresponding dovetail groove bolt 7 fixing holes on dovetail groove workbench 8 by dovetail groove bolt 7.
The screw thread corresponding with clamping screw 5 in being provided with in described positioning sleeve 3.
Embodiment: two of left and right riser 4 is welded on respectively the both sides of left and right back vertical plate 2, and whole and base plate 1 is welded as a whole, form left socle and right support, the centre of back vertical plate 2 is welded with six positioning sleeves 3 from top to bottom successively, according to the height of gib arm of crane body, four are provided with in the clamping screw 5 precession positioning sleeves 3 of locking locknut 6.In gib arm of crane body process, thereby the vibrations that occur may make, clamping screw 5 is loosening causes the location of arm body inaccurate, in order to prevent this from occurring, this positioning compression device is furnished with locking nut 6, locking nut 6 by fine setting on clamping screw 5, locking gib arm of crane body, has guaranteed the accuracy that gib arm of crane body is located
In whole installation process by regulating the length of clamping screw 5 and the upper-lower position of positioning sleeve 3 and left socle, the different spacing of right support on base plate 1 to meet gib arm of crane body fixing of different tonnages.
