Abstract

The invention relates to a device for positioning clamping jaws and a clamping device. The clamping device is used to clamp the nozzle end of a pipe fitting, and includes a jacket and clamping jaws. The clamping jaws are provided with several elastic clips, and each elastic clip There is a gap between them, the jacket is set on the outside of the jaws, the jacket and the jaws have an avoidance platform for assembling the frame of the pipe, and the jaws are installed on the device for positioning the jaws; the jacket Installed on a device for positioning the jacket, when the jacket and the jaws are circumferentially positioned and fixed to clamp the nozzle end of the pipe, the avoidance platform of the jacket and the jaw just avoids the assembled pipe frame. The advantages of the present invention are: 1. The avoidance platform of the chuck and the casing can be at a certain position, so that the chuck and the casing are fixed in the circumferential direction; 2. It avoids the installation of the chuck and the casing by threaded connection. The work on the tube expander is very heavy; 3. When in use, the collet and casing are easy to disassemble and assemble, which improves the service life.

Description

technical field

[0001] The invention relates to a device for positioning jaws and a tube clamping device. Background technique

[0002] When expanding tubes in the existing tube expander, many copper tubes to be expanded are equipped with heat dissipation fins and installed in the frame for concentrated tube expansion. The nozzle ends of the copper tubes pass through the frame frame to facilitate the tube expander The expander is limited by the structure of the frame. The clamping device used to lock the nozzle end of the copper tube of the tube expander needs to be provided with an avoidance platform to prevent the clamping device from colliding with the frame when locking the nozzle end.

[0003] The clamping device includes a chuck and a sleeve. There are several elastic clips at the end of the chuck. There are gaps between each elastic clip. The sleeve is sleeved outside the chuck and can move axially relative to the chuck. When the pipe completely covers the elastic cl...

Embodiment Construction

[0059] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0060] as attached figure 1 And attached figure 2 A clamping device is shown, which is used to clamp the nozzle end of the pipe fitting, and includes a jacket 11, jaws 21 and a frame 30, the jacket 11 is installed on the device 10 for positioning the jacket, and the jaws 21 is installed on the device 20 for positioning the jaws, and the device 10 for positioning the collet and the device 20 for positioning the jaws are installed on the frame 30 . Wherein, the jaw 21 is provided with several elastic clips, there are gaps between the elastic clips, the collet 11 is sleeved on the outside of the jaw 21 and can move axially relative to the jaw 21 so that the elastic clips radially elastically deform to clamp To tighten or loosen the nozzle end of the pipe, the jacket 11 and jaw 21 have an escape platform that avoids the frame used to a...
