Description

Tool for quickly positioning and clamping rear box body

Technical Field

The utility model belongs to the technical field of the frock, concretely relates to frock of box behind quick positioning clamping.

Background

In the process of processing the rear box body, the positioning and clamping directly influence the processing quality and efficiency of the rear box body. The rear box body needs to drill and bore inner holes and also needs to machine side faces. If a conventional vice is used for clamping, the operations of clamping → correcting point → clamping are repeated each time.

The existing scheme is that two side surfaces are machined by a milling machine, then an upper horizontal machining center clamps the two side surfaces by a vice, and then inner holes are machined, and the scheme has the following problems: 1. two devices (two procedures) are needed, wherein clamping by a small vice with clamping contact area on two side surfaces easily causes the integral inclination of parts, and the verticality of the processed inner hole cannot meet the requirement. Therefore, before each processing, a meter needs to be printed to determine whether the clamping is smooth or not, and the integral beat is invisibly influenced. 2. The side face is unqualified to be mounted on a horizontal machining center for clamping, so that the verticality of the inner hole is unqualified; 3. the contact area of the two side surfaces is small, and the horizontal machining center marks and verifies whether the whole body is inclined or not after clamping every time; 4. the continuity of part processing is not facilitated, and the overall beat is long.

The utility model provides a pair of fix a position frock of clamping back box fast, concrete scheme is as follows:

the utility model provides a frock of quick location clamping back box, includes base and locating piece, two the locating piece is symmetry respectively and installs at the base both ends, equally divide on every locating piece and do not is equipped with a plurality of location pinhole, swing joint has the locating pin on at least one location pinhole on every locating piece, and two locating piece tops symmetry respectively are equipped with the clamp plate, and two clamp plate one end is installed on the base through the support nail respectively, and every clamp plate middle part is equipped with respectively compresses tightly the hole, is equipped with respectively in every compressing tightly the hole and compresses tightly the regulating part.

Furthermore, the compression adjusting part comprises a compression screw, a first nut, a second nut and a flat washer, threaded holes are symmetrically formed in two ends of the base respectively, the two threaded holes are correspondingly formed below the compression holes respectively, one end of the compression screw penetrates through the compression hole and the first nut to be in threaded connection with the threaded holes, and the other end of the compression screw is sleeved in the flat washer to be in threaded connection with the second nut.

Furthermore, the opposite ends of the pressing plate are respectively and symmetrically provided with a groove.

Furthermore, bayonets are respectively arranged at the end heads of the two ends of the base.

Furthermore, the distance between the two positioning blocks is set according to the length of the rear box body which needs to be positioned and clamped.

The advantages of the utility model

The utility model discloses the quick location of box after quick location clamping box is passed through locating piece and locating pin realization, through the compression screw adjusting plate height, realizes the quick-witted tight of back box, location and clamping convenient and fast have improved the efficiency of clamping effectively, and simple structure, and convenient to use is fit for promoting.

Detailed Description

The present invention will be further explained with reference to the drawings and the following detailed description, wherein it should be noted that the present embodiment is not intended to limit the scope of the present invention.

As shown in fig. 1 to 4, the tool for quickly positioning and clamping the rear box body of the embodiment includes a base 1 and positioning blocks 2, the two positioning blocks 2 are symmetrically installed at two ends of the base 1 through bolts 11, respectively, and the distance between the two positioning blocks 2 is set according to the length of the rear box body 15 to be positioned and clamped. A plurality of symmetrical positioning pin holes 4 are respectively formed in each positioning block 2, and the purpose is that after the frequently-used positioning pin holes 4 are worn, the frequently-used positioning pin holes 4 can be replaced to another positioning pin hole 4 for positioning. And at least one positioning pin hole 4 on each positioning block 2 is provided with a positioning pin 5, so that the problem of quick positioning and clamping of the rear box body 15 is solved by positioning one side and two pins. The pressing plates 3 are symmetrically arranged above the two positioning blocks 2 respectively, and the pressing plates 3 are used for adjusting the height of the pressing plates 3 through pressing the adjusting parts so as to clamp and loosen the rear box body 15. The opposite sides of the pressing plate 3 are respectively symmetrically provided with a groove 12, and the grooves 12 are used for avoiding the protruding parts at the two sides of the rear box body 15, so that the clamping quality is ensured. One end of each of the two pressing plates 3 is mounted on the base 1 through a supporting nail 7, a pressing hole 13 is formed in the middle of each pressing plate 3, a pressing adjusting part is arranged in each pressing hole 13, specifically, each pressing adjusting part comprises a pressing screw 6, a first nut 10, a second nut 9 and a flat washer 8, threaded holes (not shown) are symmetrically formed in two ends of the base 1 respectively, the two threaded holes are correspondingly formed below the pressing holes 13 respectively, one end of each pressing screw 6 penetrates through the corresponding pressing hole 13 and the first nut 10 to be in threaded connection with the corresponding threaded hole, and the other end of each pressing screw is sleeved into the corresponding flat washer 8 to be in threaded connection with the second nut 9. The function of the pressing adjusting piece is to adjust the height of the pressing plate 3 so as to clamp and release the rear box body 14. Bayonets 14 are respectively arranged at the two ends of the base 1. The bayonet 14 is used for clamping a bolt to connect the tool with a machine tool.

When the positioning device is used, the rear box body 14 is placed on the two positioning blocks 2, holes at four ends of the rear box body 14 are respectively aligned to the positioning pin holes 4 on the two positioning blocks 2, and the positioning pins 5 are inserted into the two positioning pin holes 4 on the diagonal lines of the positioning blocks 2, so that the rear box body 14 is quickly positioned. And the two second nuts 9 are screwed down, so that the two pressing plates 3 respectively press the rear box body 14, and quick clamping is realized.
