Currently, pipe fitting is used widely in every field, in the process of pipe fitting, the fixation of pipe fitting is to compare Important program, however plumbing dimensions are varied, fixture fails to well adapt to plumbing dimensions, causes clamping unstable, pipe fitting It is loosened when processing；The prior art mostly uses greatly multi-direction adjustment simultaneously, it is easy to the feelings of pipe fitting eccentric axis occurs Condition occurs.
Invention content
(1) the technical issues of solving
Present invention aims to overcome that the shortcomings of the prior art, and a kind of fixture work convenient for equidistantly adjusting is provided Dress.
(2) technical solution
A kind of clamp fixture convenient for equidistantly adjusting, including chassis, shaft and clamping plate；Branch is symmetrically arranged on the chassis Plate, two support plate lines correspond to one string of chassis, which is separated into a major arc area, a minor arc area by chassis, which, which corresponds to, hangs down Directly with one diameter A of chassis；The shaft passes through and is rotatablely connected support plate, and shaft one end is additionally provided with handwheel；The shaft is located at Support plate medial segment is symmetrily processed with the same specification screw thread of both ends counterturn, and is bolted with travelling nut respectively；The mobile spiral shell Generatrix is connected with clamping plate to major arc area, and clamping plate stage casing is provided with bending；The clamping plate itself is symmetrical with bending end line, bending end Line, which corresponds to, to be overlapped and another diameter B in chassis；The diameter B is vertical with diameter A；One end bottom of the clamping plate far from travelling nut Face is provided with No.1 sliding block, and chassis is correspondingly arranged on No.1 sliding slot, and No.1 sliding slot is parallel with shaft.
Preferably, the bending end angle is 120~140 °.
Preferably, the bending end angle is 135 °.
Preferably, the corresponding central angle in the major arc area is 70~85 °.
Preferably, the corresponding central angle in the major arc area is 70~85 °.
Preferably, the chassis corresponds to bending end mobile route and is provided with No. two sliding slots, and bending end bottom surface is provided with No. two Sliding block, No. two sliding blocks are slidably connected with No. two sliding slots.
Preferably, the shaft is rotatablely connected support plate by bearing.
(3) advantageous effect
The present invention provides a kind of clamp fixture convenient for equidistantly adjusting, and clamping plate bending end line corresponds to and chassis diameter, leads to When crossing handwheel and rotating shaft, travelling nut is mutually equidistant close to each other or separate, at the same drive clamping plate equidistant close to each other or It is separate, to realize that the size adjustment of clamping zone is held in position center not in the case where completing to adapt to tube outer diameter Just, easy to operate.
Description of the drawings
In order to illustrate the technical solution of the embodiments of the present invention more clearly, will be described below to embodiment required Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only some embodiments that the present invention protects, for For those of ordinary skill in the art, without creative efforts, other are can also be obtained according to these attached drawings Attached drawing.

Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained all other without creative efforts Embodiment shall fall within the protection scope of the present invention.
Referring to attached drawing, a kind of clamp fixture convenient for equidistantly adjusting, including chassis 1, shaft 2 and clamping plate 3；It is right on chassis 1 Title is connected with support plate 101, and two support plate lines correspond to 1 one string of chassis, which is separated into a major arc area, a minor arc by chassis 1 Area, the string correspond to vertically with one diameter A of chassis；Shaft 2 passes through and is rotatablely connected support plate 101, and 2 one end of shaft is also equipped with hand Wheel 201；Shaft 2 is located at 101 medial segment of support plate and is symmetrily processed with the same specification screw thread 202 of both ends counterturn, and is spirally connected respectively There is travelling nut 203；Travelling nut 203 is connected with clamping plate 3 towards major arc area, and 3 stage casing of clamping plate is machined with bending；Clamping plate 3 itself Symmetrical with bending end line, bending end line, which corresponds to, to be overlapped and another diameter B in chassis；Diameter B is vertical with diameter A；Clamping plate 3 is separate One end bottom surface of travelling nut 203 is machined with No.1 sliding block 301, and chassis 1 corresponds to and is machined with No.1 sliding slot 102, No.1 sliding slot 102 It is parallel with shaft 2.
Wherein, bending end angle is 120~140 °.
Wherein, the corresponding central angle in major arc area is 70~85 °.
Wherein, shaft 2 is rotatablely connected support plate 101 by bearing.
In one embodiment, bending end angle is 135 °, and the corresponding central angle in major arc area is 83 °.
In another embodiment, chassis 1 corresponds to bending end mobile route and is machined with No. two sliding slots 103, bending end bottom surface No. two sliding blocks 302 are machined with, No. two sliding blocks 302 are slidably connected with No. two sliding slots 103.
Due to present apparatus structure special designing, when shaft 2 being rotated by handwheel 201, the mutually equidistant phase of travelling nut 203 Mutually closer or far from while driving clamping plate 3 equidistant close to each other or separate, to realize the size adjustment of clamping zone, complete In the case that pairs of tube outer diameter adapts to, it is held in position center inconvenience, it is easy to operate.
Present invention disclosed above preferred embodiment is only intended to help to illustrate the present invention.There is no detailed for preferred embodiment All details are described, also do not limit the specific implementation mode that the invention is only.Obviously, according to the content of this specification, can make Many modifications and variations.These embodiments are chosen and specifically described to this specification, is in order to preferably explain the original of the present invention Reason and practical application, to enable skilled artisan to be best understood by and utilize the present invention.The present invention is only authorized The limitation of sharp claim and its full scope and equivalent.
