Description

Novel multi-aperture sleeve of laser pipe cutting machine Technical Field The utility model mainly relates to a sleeve for stabilizing a pipe on a laser pipe cutting machine. Background In the production process of the laser pipe cutting machine, a device for stabilizing the pipe, namely a sleeve, is arranged, and the precision and the stability of the sleeve influence the precision and the stability of the produced product. In a traditional laser pipe cutting machine, most of sleeves are of a metal or nonmetal cylinder structure with outer diameters adaptive to a base and inner diameters adaptive to cutting pipes. The design has very high requirements on the precision, the roughness and the coaxiality of the outer cylindrical surface and the inner hole of the sleeve, meanwhile, due to unavoidable coaxiality difference, the same sleeve can not reach the repeated position consistent with the position before disassembly due to rotation and the like after being disassembled, so that the production equipment is stopped and debugged again, the efficiency is seriously affected, in addition, each sleeve corresponds to only one pipe diameter, when the multi-specification large-scale production is carried out, a plurality of sleeves with different inner diameters are needed to meet the production requirements of pipes with various specifications, and the management cost and the storage cost during the production are greatly improved. Disclosure of utility model In order to overcome the defects, the patent provides a novel multi-aperture sleeve of a laser pipe cutting machine, solves the defects of high manufacturing precision requirement, poor position repeatability and low applicability of the conventional sleeve, and is a multi-aperture sleeve capable of self-positioning and low in manufacturing precision requirement and a matched locking device. The purpose of the utility model is realized in the following way: The utility model provides a novel multi-aperture sleeve of laser pipe cutting machine, it includes the sleeve base, the through-hole is seted up to the front and back direction of sleeve base, and the bottom of sleeve base's through-hole is the back taper, and the sleeve is placed in the centre of through-hole, the sleeve is the regular prism, and a telescopic edges card is in the bottom of through-hole, a hole has been seted up on the terminal surface of every edge to the sleeve, and the aperture in every hole is different, inserts tubular product in the hole, the top level setting of through-hole is provided with a locking fixture block between through-hole top and the telescopic top, the top level of locking fixture block, the bottom is a toper breach, and the sleeve is blocked from top to bottom simultaneously to toper breach and the bottom of through-hole, and a locking screw hole has been seted up at sleeve base top, and locking screw is downthehole to be inserted from the locking screw, pushes down locking fixture block, supports the sleeve. And the aperture corresponding to the working position is etched outside each prismatic surface of the sleeve. A rectangular observation hole is formed in the side face of the sleeve base. The beneficial effects of the utility model are as follows: 1. The traditional sleeve is changed into a regular prism from the shape of a cylinder, the bottom of a through hole of a sleeve base is consistent with the shape of the outer cylinder of the sleeve, so that the self-positioning can be realized under the pressure of a tightening mechanism, and the same sleeve can still keep the consistency of positions before and after the sleeve is converted into different pipe diameters or disassembled. 2. The locking mode of the traditional sleeve is changed into that a locking screw pushes a locking clamping block, and the sleeve is locked by a sleeve base clamping groove consistent with the outer cylindrical surface of the sleeve, so that the scattered stress is realized, and the deformation of the sleeves made of different materials due to the locking device is reduced. 3. A hole is formed in the end face of each edge of the sleeve, the aperture of each hole is different, and therefore the same sleeve is applicable to different pipes. Taking regular hexagonal prism as an example, six kinds of pipes with different apertures can exist on one sleeve at the same time, the apertures corresponding to the working positions are etched on each surface of the regular hexagonal prism sleeve, and meanwhile, rectangular through holes are formed in the side edge of the sleeve base, so that the aperture of the sleeve currently in use can be conveniently confirmed. 4. The diameter adduction of sleeve head end keeps the pore wall of partial length simultaneously, and when cutting in suitable position, this partial pore wall can hold up tubular product and can restrict its rocking, and tubular product sagging problem when avoiding cutting long product simultaneously.
