Description
Technical field
The invention belongs to field of mechanical technique, are related to a kind of pipe fitting clamping rotating mechanism.
Background technique
With the development of medical instrument, the impedance-pH electrode catheter demand for esophageal pH monitoring is growing day by day, to resistance
The production capacity demand of anti-pH electrode catheter is larger.During being processed to impedance-pH electrode catheter, need to being wound around
Conducting wire on electrode catheter carries out stripping operation.The usual manner for currently carrying out depainting to enameled wire has chemical agent depainting, height
Temperature barbecue depainting, blade sand paper external force scrape depainting etc..However it is directed to the enamel-cover that flexible, non-refractory tubing is externally wrapped with
Line, the especially thin enameled wire such as hair, current mode such as blade sand paper there is scrape low efficiency, easily enameled wire scraped it is disconnected
The problem of；When electrode catheter is not heatproof material, the insulated paint for managing outer coiling cannot be removed by the methods of high temperature；Pass through people
There are inefficiency, at high cost for work depainting, and depainting dynamics and position can not be controlled, and the low and consistent property of qualification rate is poor.
For this purpose, principle is to clamp the both ends of hose applicant has invented a kind of painting stripping mechanism of enameled wire, with
It drives hose to rotate around own central axis line by rotating device afterwards, while grinding device is set in the side of hose, pass through polishing
The grinding head of device and the catheter contact of rotation can effectively remove the insulated paint of coiling outside pipe.In actual use, it finds general
Logical clamping device (such as crocodile clip) easily leads to hose deformation, it is difficult to carry out rotary operation, while clamp not strongly admittedly, hose is easily loose
It is de-.
Summary of the invention
The purpose of the present invention is there is the above problem in view of the prior art, a kind of pipe fitting folder of good clamping effect is proposed
Hold rotating mechanism.
Object of the invention can be realized by the following technical scheme:
Pipe fitting clamps rotating mechanism, including pedestal and the shaft that is arranged in pedestal, has in the shaft and shaft
The axis hole of coaxial arrangement, which is characterized in that the clamp with shaft coaxial arrangement is equipped in the axis hole, in the clamp
Equipped with the annular clamping structure just circumferentially clamped when clamp is moved axially away from pipe fitting, it is equipped between the shaft and clamp
Driving structure for driving clamp to move always to the direction far from pipe fitting.
When clamping pipe fitting, pipe fitting is extend into the annular clamping structure in clamp, makes to press from both sides under the action of driving structure
Pipe is axial to the end motion far from pipe fitting, until annular clamping structure circumferentially clamps pipe fitting.Shaft can be on the base along itself
Central axes rotation can drive pipe fitting to rotate along central axes, to reach rotation when shaft rotation by annular clamping structure
Purpose.When needing to unclamp, an opposite force is applied to clamp, the direction of the opposite force and driving structure are applied to power on clamp
Contrary, the frictional force of annular clamping structure and pipe fitting reduces, and can extract pipe fitting out of clamp.
