Drilling fixture for plastic pipe

Abstract

The invention provides a drilling fixture for a plastic pipe. The drilling fixture comprises a base and a clamping mechanism which are in sliding connection with each other through cooperation of guide rails and sliding blocks, wherein a straight-line motion mechanism is arranged between the base and the clamping mechanism, and comprises a lead screw nut pair of which the axis is parallel to the sliding direction of the sliding blocks; the top of a nut on the lead screw nut pair is fixedly connected with the bottom of the clamping mechanism; a support is fixed on the base; a drilling die is arranged on the support; a first through hole capable of accommodating the drilling die is formed in the support; the clamping mechanism comprises a baseplate and brackets; a V-shaped groove is formed in the cross section of each bracket; and a flexible steel belt is connected with the two sides of each bracket through locking bolts. The drilling fixture provided by the invention has the advantages that through the regulation of pipe diameters and drilling positions, relatively-high-precision drilling on plastic pipes of different specifications on a common drilling machine can be achieved; the structure is simple; and the operation is easy.

Description

technical field [0001] The invention belongs to the field of fixtures, in particular to a drilling fixture for plastic pipe fittings. Background technique [0002] In applications in various fields, the proportion of plastics is increasing, and with the development of society, people's requirements for plastic parts are getting higher and higher. Traditional plastic parts are generally produced by direct molding. The parts produced by this method have low precision and cannot form relatively complex plastic parts, which is far from meeting people's use requirements. For this type of plastic parts, cutting methods are often used, and the cutting processing equipment used usually uses Cutting equipment for metal processing. Among them, turning is the most commonly used and most typical cutting processing method. Due to the large difference between plastics and metals, and in order to avoid damage to plastic parts, it cannot be used when clamping plastic parts. The original ji...

[0002] In applications in various fields, the proportion of plastics is increasing, and with the development of society, people's requirements for plastic parts are getting higher and higher. Traditional plastic parts are generally produced by direct molding. The parts produced by this method have low precision and cannot form relatively complex plastic parts, which is far from meeting people's use requirements. For this type of plastic parts, cutting methods are often used, and the cutting processing equipment used usually uses Cutting equipment for metal processing. Among them, turning is the most commonly used and most typical cutting processing method. Due to the large difference between plastics and metals, and in order to avoid damage to plastic parts, it cannot be used when clamping plastic parts. The original jig used for processing metal parts, when drilling plastic pipe fittings, in order to achieve higher precision requirements, it is necessary to design a special drilling jig for plastic pipe fittings
