Detailed Description
Referring to fig. 1-3, the clamping mechanism for cutting plastic pipes provided by the present invention includes a supporting seat 1, a positioning tube 2, a clamping block 3, a control rod 4 and an outer circle positioning fixture 5. Wherein: the positioning tube 2 is preferably horizontally fixedly mounted on the support base 1. One end of the positioning tube 2 is connected with at least two clamping blocks 3 which can move along the radial direction of the positioning tube 2. The clamping blocks 3 are distributed in a circumferential array mode around the axis of the positioning pipe 2, the outer side faces of the clamping blocks 3 are arc-shaped faces, anti-skidding convex lines are arranged on the outer side faces of the clamping blocks 3, and the clamping blocks 3 are used for supporting the inner wall of a clamping pipe.
The operating rod 4 is installed in the positioning tube 2 in a matching mode, one end of the operating rod 4 is provided with a conical rod head 41, the conical surface of the conical rod head 41 is located on the circumferential direction of the operating rod 4, the inner side surface of the clamping block 3 is matched with the conical surface of the conical rod head 41, and the outer side surface of the clamping block 3 matched with the conical surface of the conical rod head 41 is axially parallel to the positioning tube 2. When the tapered rod head 41 is moved axially along the positioning tube 2, each clamping block 3 is selectively driven to radially expand along the positioning tube 2 to clamp the inner wall of the tube or to converge to cancel clamping of the tube.
The outer circle positioning clamp 5 is arranged around the clamping block 3 and used for clamping the outer wall of the pipe, and the clamping center of the outer circle positioning clamp 5 is concentric with the clamping center of the clamping block 3. The outer circle positioning jig 5 may be a jig known to those skilled in the art, such as a chuck jig or a circular arc jig.
As shown in fig. 1, when clamping a plastic pipe, the clamping mechanism of this embodiment may first sleeve the plastic pipe on the positioning tube 2, then move the control rod 4 to make the tapered rod head 41 drive the clamping block 3 to open and support and clamp on the inner wall of the plastic pipe, then clamp on the outer wall of the plastic pipe through the outer circle positioning clamp 5, and finally position and lock the inner and outer clamps to complete the clamping operation of the plastic pipe, so as to ensure that the pipe will not deform and move during the subsequent cutting process. In the process of clamping the pipe by the clamping mechanism, the plastic pipe wall is clamped by the radial acting force with the same bidirectional force, so that the clamping is easier, and the bending deformation of the pipe wall can be prevented.
In this embodiment, as for the connection manner of the clamping blocks 3 and the positioning tube 2, the short rods 6 may be hinged between the tube end of the positioning tube 2 and each clamping block 3, and the clamping blocks 3 may be slidably mounted on radial sliding grooves provided on the tube wall of the positioning tube 2, as long as the direct or indirect connection manner known to those skilled in the art can be used to allow the clamping blocks 3 to move a certain distance along the radial direction of the positioning tube 2.
In a further embodiment, the positioning tube 2 comprises an internally threaded tube 21 and an arm tube 22, the clamping block 3 is arranged at one end of the arm tube 22, and the other end of the arm tube 22 is detachably connected with one end of the internally threaded tube 21. Because the pipe to be clamped is only sleeved from one end of the positioning pipe 2, and the other end of the positioning pipe 2 needs to be provided with a support, the arm pipe 22 is detachably arranged, and the arm pipe 22 with different diameters and the matched clamping block 3 can be replaced conveniently to be suitable for pipes with different inner diameters.
For the control rod 4 driving the clamping block 3 by moving, the control rod 4 and the clamping block 3 after clamping the pipe need to be locked, and preferably, the control rod 4 is in threaded fit with the inner wall of the internal threaded pipe 21.
Accordingly, in order to fit the arm tubes 22 of different diameters, the control lever 4 includes a screw rod 42 and a link rod 43, and the tapered rod head 41 is provided at one end of the link rod 43, and the other end of the link rod 43 and the screw rod 42 are detachably connected by a screw connection. The control rod 4 is in threaded fit with the internally threaded tube 21 through the screw rod 42, and the connecting rod 43 is in fit with the inner wall of the arm tube 22. A hand wheel 44 is fixedly arranged at one end of the screw rod 42, so that the control rod 4 is more conveniently controlled.
As shown in fig. 2, the outer wall of the arm tube 22 is provided with scale marks 23 along the axial direction, and the scale marks 23 are used for measuring the length of the allowance which can be reserved when the tube is cut. Because the pipe needs the suit on registration arm 2 when the centre gripping, the pipe length of cutting the removal is for being located the front end portion of grip block 3, consequently can be based on the part that registration arm 2 eats into the pipe and does the surplus length of reference calculation pipe, consequently, scale mark 23 is more convenient for calculate the pipe and cuts the size.
Because the clamping block 3 is inconvenient to observe in the position of the inside of the pipe, in order to determine the cutting position, the outer end of the clamping block 3 is further provided with a cutting station window 7, the outer end of the clamping block 3 does not exceed the outer side surface of the cutting station window 7, the cutting station window 7 can be used as a cutting position mark to limit the maximum cutting length of the clamped pipe, and the clamping block 3 is prevented from being cut when the pipe is cut. And a waste collecting groove 8 is also fixed outside the cutting station window 7.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
