Abstract

The invention discloses circular tube drilling equipment with a convenient and reliable locating function, and belongs to the technical field of circular tube machining clamps. The circular tube drilling equipment comprises a machine frame. A clamp is arranged on the machine frame, and a drill bit is arranged at the position, above the clamp correspondingly, of the machine frame. The clamp comprises box iron, and fixtures are distributed in a groove of the box iron in the length direction. Each fixture comprises an upper V-shaped block and a lower V-shaped block, wherein the lower V-shaped block is fixedly arranged in the groove of the box iron, and a V-shaped groove of the upper V-shaped block and a V-shaped groove of the lower V-shaped block are opposite. Guiding pins are fixed on the lower V-shaped blocks, and through holes correspondingly matched with the guiding pins are formed in the upper V-shaped blocks. The guiding pins are sleeved with springs, and the two ends of each spring abut against the upper V-shaped blocks and the lower V-shaped blocks respectively. A locking shaft and a locking cam fixed on the locking shaft are arranged above each upper V-shaped block, and the locking shafts are rotatably arranged on the box iron. The circular tube drilling equipment with the convenient and reliable locating function is simpler and quicker to use and improves the work efficiency.

Description

A kind ofly locate convenient and reliable pipe rig

Technical field

The present invention relates to pipe clamp for machining technical field, locate convenient and reliable pipe rig in particular to a kind of.

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 rig that cost is low, location is convenient, reliability is high location is convenient and reliable, to solve the problem.

For realizing the object of the invention, the technical scheme of employing is: a kind ofly locate convenient and reliable pipe rig, and comprise frame, frame is provided with fixture, and in frame, the top of corresponding fixture is provided with drill bit; Described fixture comprises channel-section steel, is placed with jig along its length in the groove of channel-section steel; Described jig comprises V-block, lower V-block, 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, upper V-block offers adaptive through hole corresponding to guide finger, be arranged with spring outside guide finger, the two ends of spring abut with upper V-block, lower V-block respectively; 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.

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.

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 being 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, ensure 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, improve operating efficiency, reliability is high.

Accompanying drawing explanation

Fig. 1 is the top view of the fixture of the convenient and reliable pipe rig in location provided by the invention;

Fig. 2 is A-A 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 show the convenient and reliable pipe rig in location provided by the invention, and comprise frame, frame is provided with fixture, and in frame, the top of corresponding fixture is provided with drill bit; Fixture comprises channel-section steel 1, is placed with jig 2 along its length in the groove of 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, and guide finger 23 is through in through hole, upper V-block 21 is elevated along guide finger 23 slip by through hole, to loosen and to clamp, be arranged with spring 4 outside guide finger 23, the two ends of spring 4 abut with upper V-block 21, lower V-block 22 respectively; 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 and to automatically reset.

One end in channel-section steel 1 is provided with baffle plate 3, one end of pipe is located, is convenient to the processing such as boring, cutting.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.

One end of lock shaft 24 is provided with handle, and handle can relative to lock shaft 24 in obtuse angle, and handled easily exerts a force.Guide finger 23 is two, and is symmetricly set on the V-type groove both sides of lower V-block 22, makes the clamping of upper V-block 21 and unclamp smooth and easy stable by the structure of guiding.

The quantity of jig 2 can set distribution according to actual overall processing pipe length.

The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
