Description

A kind of pipe boring grab

Technical field

The present invention relates to pipe clamp for machining technical field, in particular to a kind of pipe boring grab.

Background technology

Pipe is a kind of main section bar, and it is applied widely, such as, as device framework, mechanical equipment component, tools production component etc.For the processing clamping relative difficult of pipe, the tension of folder easily produces distortion, and catcher mark can be left on its surface, if folder is more loose, easily makes its jaw that flies out, cause security incident, so no matter do nock processing or hole or cutting processing, fixing to clamp of pipe is most important, and hand actuable clamping device most is at present difficult to meet the demands, the employing Digit Control Machine Tool processing also had, but its cost is higher, is difficult to extensive use.

Summary of the invention

The object of the present invention is to provide a kind ofly can effectively to clamp, pipe boring grab that cost is low, to solve the problem.

For realizing the object of the invention, the technical scheme of employing is: a kind of pipe boring grab, comprises channel-section steel, is provided with jig and regulates V-block in channel-section steel; Described jig comprises V-block, lower V-block, and lower V-block is fixedly installed in the groove of channel-section steel, and the V-type groove of upper V-block and lower V-block is oppositely arranged; Lower V-block is fixed with guide finger, and upper V-block offers adaptive through hole corresponding to guide finger, and be arranged with spring outside guide finger, the two ends of spring abut with upper V-block, lower V-block respectively; Guide finger stretches out V-block through through hole, and the end thread of stretching out V-block is connected with stop nut; The top of upper V-block is provided with lock shaft and is fixed on the lock cam on lock shaft, and lock shaft rotates and is arranged on channel-section steel; The V-type groove both sides of described adjustment V-block offer adjustment screwed hole, and regulate in screwed hole and be connected with adjusting bolt, the bottom of adjusting bolt is against on channel-section steel; Regulate V-block also to offer fixed via, be provided with fixed leg in fixed via, one end of fixed leg is fixed on channel-section steel, and the other end is provided with external screw thread, and external screw thread place is provided with nut.

Further, the one end in described channel-section steel is provided with baffle plate.

Further, the V-type rooved face of described upper V-block and lower V-block is covered with layer of polyurethane.

Further, one end of described lock shaft is provided with handle.

Further, described guide finger is two, and is symmetricly set on the V-type groove both sides of lower V-block.

Further, described fixed via is two, and is symmetricly set on the V-type groove both sides regulating V-block.

The invention has the beneficial effects as follows, by the cooperation of upper V-block and lower V-block and the structure of rotating gripping cams, the spacing fixing of radial direction is carried out to pipe, realizing the effective clamping to pipe, also by arranging baffle plate in channel-section steel one end to realize axial location, ensureing the perpendicularity of end face, by rotation lock mandrel during operation, lock cam is pushed against on V-block and realizes clamping, simple and fast, improves operating efficiency.

Fig. 1 is the top view of pipe boring grab provided by the invention;

Fig. 2 is A-A place sectional view in Fig. 1;

Fig. 3 is B-B place sectional view in Fig. 1.

Detailed description of the invention

Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.

Fig. 1, Fig. 2, Fig. 3 show pipe boring grab provided by the invention, comprise channel-section steel 1, be provided with jig 2 and regulate V-block 4 in channel-section steel 1; Jig 2 comprises V-block 21, lower V-block 22, lower V-block 22 is fixedly installed in the groove of channel-section steel 1, the V-type groove of upper V-block 21 and lower V-block 22 is oppositely arranged, lower V-block 22 is fixed with guide finger 23, and upper V-block 21 offers adaptive through hole corresponding to guide finger 23, is arranged with spring 5 outside guide finger 23, the two ends of spring 5 abut with upper V-block 21, lower V-block 22 respectively, guide finger 23 is through in through hole, and upper V-block 21 is elevated, to loosen and to clamp along guide finger 23 slip by through hole; Guide finger 23 stretches out V-block 21 through through hole, and the end thread of stretching out V-block 21 is connected with stop nut 6; The top of upper V-block 21 is provided with lock shaft 24 and the lock cam 25 be fixed on lock shaft 24, lock shaft 24 rotates and is arranged on channel-section steel 1, by arranging the rotating support of bearing realization to lock shaft 24 at two walls of channel-section steel 1, during clamping and release, V-block 21 can be made under spring force to move up automatically reset, meanwhile, play firmly spacing effect according to the stop nut 6 that different tube diameters regulates, prevent V-block 21 from ejecting and depart from.

Regulate the V-type groove both sides of V-block 4 to offer adjustment screwed hole, regulate in screwed hole and be connected with adjusting bolt 43, the bottom of adjusting bolt 43 is against on channel-section steel 1; Regulate V-block 4 also to offer fixed via, be provided with fixed leg 41 in fixed via, one end of fixed leg 41 is fixed on channel-section steel 1, and the other end is provided with external screw thread, and external screw thread place is provided with nut 42.Adjusting bolt 43 adopts interior fancy or inner cross, avoids adopting outer-hexagonal head and interfering with nut 42.Regulating the height of V-block 4 by rotating adjusting bolt 43 adjustment, playing the supporting role to tubing, preventing from down taking, jig 2 can better be clamped, after adjusting bearing height, being fixed by nut 42.

One end in channel-section steel 1 is provided with baffle plate 3, and one end of pipe is located, and is convenient to the processing of boring location.In order to prevent leaving clamping scar at the outer surface of pipe, being covered with layer of polyurethane at the V-type rooved face of upper V-block 21 and lower V-block 22, stable clamping can being realized, can play a protective role again.
