Abstract
The invention discloses a clamp for a circular tube. The clamp for the circular tube comprises a clamp platform and clamping devices. A rotating body is arranged on the clamp platform. The section of the rotating body is in the shape of a regular triangle. A through hole is formed in the center of the rotating body. An annular fixed platform is arranged in the through hole. The center of the section of the rotating body and the center of the section of the fixed platform coincide. The fixed platform is fixed to the clamp platform. The upper surface of the fixed platform and the upper surface of the rotating body are identical in height. The number of the clamping devices is three. The clamping devices are arranged on the upper surface of the fixed platform and the upper surface of the rotating body in an annular array mode. According to the clamp for the circular tube, the rotating body is driven by a pushing device to rotate in the clockwise direction; due to the fact that the three clamping devices are arranged on the fixed platform and the rotating body in the annular array mode, equal thrust is exerted on clamping jaws under the action of a directional platform through a first stay rod and a second stay rod when the rotating body rotates, the pressures exerted on the circular tube in all the directions are identical, the circular tube can be stably fixed, and the circular tube is prevented from deforming; in this way, the clamp for the circular tube is convenient to use and reliable.

Oriented conduit, the extended line of oriented conduit points to the ring heart in fixed station section, and one end of first support bar is fixed on by rotating shaft
Rotary body upper surface, the other end is connected with one end of second support bar by rotating shaft, and second support bar is through oriented conduit from calmly
To being stretched out on the inside of platform, the other end of second support bar is provided with arc clamping jaw.
Preferably, a side of the rotary body is externally provided with pushing meanss, and the pushing meanss are fixed on clamping fixture table,
Rotary body can be promoted to prolong be rotated clockwise moving.
Preferably, the pushing meanss include guide table, the first push rod and the second push rod, and the guide table is fixed on fixture
On platform, institute's guide table is provided with guide duct, and one end of the first push rod passes through the one of rotating shaft and the second push rod through guide duct
End is connected, and the other end is provided with crank, and the other end of the second push rod is connected with one side of rotary body by rotating shaft, the first push rod
Outside with corresponding screw thread is provided with the inside of guide duct.
Preferably, the bottom of the rotary body is provided with endless glide, the ring heart of endless glide and the ring heart of annular fixed station
Overlap, the upper surface of the clamping fixture table is provided with the annular groove corresponding with endless glide.
The beneficial effect that is reached of the present invention is：By pushing meanss be rotated body prolong rotationally clockwise, due to
Permutation is set so rotary body can be by the when rotating in a ring on fixed station and rotary body for three clamping devices
One strut and the second strut, respectively to the thrust that clamping jaw is equal, make pipe suffered in all directions in the presence of orientation device
Pressure it is identical, can stabilization fix pipe and not result in its deformation, it is convenient and reliable.
Brief description of the drawings
Fig. 1 is overlooking the structure diagram of the invention；
Fig. 2 is the structural representation of rotary body bottom in the present invention；
Fig. 3 is the structural representation of clamping fixture table upper surface in the present invention.
Specific embodiment
In order to further describe technical characterstic of the invention and effect, below in conjunction with the drawings and specific embodiments to this hair
It is bright to be described further.
Referring to figs. 1 to Fig. 3, a kind of pipe fixture, including clamping fixture table 1, clamping device 2, the clamping fixture table 1 is provided with rotation
Body 3, the section of the rotary body 3 is in equilateral triangle, and centre is provided with through hole 8, through hole 8 and is provided with annular fixed station 4, rotary body 3
Section overlapped with the kernel of section of fixed station 4, fixed station 4 is fixed on clamping fixture table 1, the upper table of its upper surface and rotary body 3
Face is highly consistent, and the quantity of the clamping device 2 is three, is set in the upper surface circular array of fixed station 4 and rotary body 3
Put.
Further, the clamping device 2 includes orientation device 21, first support bar 22 and second support bar 23, described fixed
To oriented conduit is provided with platform 21, the extended line of oriented conduit points to the ring heart in fixed station section, one end of first support bar 22
The upper surface of rotary body 3 is fixed on by rotating shaft, the other end is connected with one end of second support bar 23 by rotating shaft, second support bar
23 stretch out through oriented conduit from the inner side of orientation device 21, and the other end of second support bar 23 is provided with arc clamping jaw 24.
Further, a side of the rotary body 3 is externally provided with pushing meanss 5, and the pushing meanss 5 are fixed on fixture
On platform 1, rotary body 3 can be promoted to prolong and to be rotated clockwise moving.
Further, it is characterised in that：The pushing meanss 5 include guide table 51, the first push rod 52 and the second push rod 53,
