Abstract

An oblate insulated screw turning chucking consists of an ejecting needle barrel, a cartridge and a slip bolt. An end of the ejecting needle barrel has a centre hole, the other end of the ejecting needle barrel has a workpiece back cut; the cartridge has a workpiece groove across the central axle, the slip bolt is inserted into the workpiece groove of the cartridge. The utility model chucking can be used for machining pure fiber material oblate screw, the tensile intensity is high, the insulating property is perfect, the material charge is low, and the machining cost is low.

Description

A kind of oblate insulation blanket stud turning clamp

Technical field:

The utility model relates to a kind of machined into anchor clamps, is specifically related to a kind of oblate insulation blanket stud turning clamp.

Background technology:

Insulation blanket stud is a kind of securing member commonly used on the high voltage electrical product.Insulation blanket stud adopts a kind of insulating materials through specially treated usually, and its material can satisfy the requirement of processing screw rod.But insulating board is because the material pine is thin, layering easily, can not process by the method for other insulation blanket stud, therefore, significant advantage performances such as Master Cost is low though insulating board has, tensile strength can meet the demands, insulating properties are reliable can not be applied on the high voltage electrical insulation blanket stud.

Summary of the invention:

Technical problem to be solved in the utility model is: solve prior art and can't solve the problem that insulating board carries out machined into, and a kind of turning clamp that can insulating board material is loose, layering easily be processed into tensile strength height, good insulation preformance, oblate insulation blanket stud that Master Cost is low is provided.

The technical solution adopted in the utility model is: this oblate insulation blanket stud turning clamp is made up of tailstock barrel, chuck, pin, tailstock barrel one end has centre hole, the tailstock barrel other end has the workpiece inverted draw cut, and chuck has the workpiece groove of a mistake central shaft, and pin inserts in the workpiece groove of chuck.

When using the utility model anchor clamps, the thimble of lathe withstands in the hole of tailstock barrel, and insulating board workpiece one end inserts in the inverted draw cut, and the workpiece other end passes the workpiece groove of chuck, inserts pin from the workpiece notch.Three-jaw chuck one pawl of lathe holds out against workpiece fixing in the pin position.Thereby the utility model has solved the technical barrier that material is loose, insulating board layering easily is processed into insulation blanket stud, the screw rod oblate made of paper that adopts the turning of these anchor clamps to process, tensile strength can meet the demands, insulating properties are more reliable than other insulation blanket stud, and have advantages such as Master Cost is low, processing cost is few.The utility model provides a kind of novel clamp for machined into turning high voltage electrical securing member.

The specific embodiment:

Referring to Fig. 1～Fig. 5, be that the oblate screw rod of 18 * 8 rectangular cardboard billot processing M16 is an example with blank, the specific embodiment of the present utility model is described:

The utility model is to play workpiece location is made a kind of anchor clamps of blowing with preventing a end because of lathe thimble top tight workpiece when cutted thread.

1, anchor clamps are made up of tailstock barrel 1, chuck 2, pin 3 three parts as shown in Figure 1, and 4 is workpiece to be machined among the figure.Press Fig. 1 anchor clamps with on the workpiece clamp, the three-jaw head-clamp of lathe is lived chuck 2, and wherein a pawl is clipped on the pin 3, and the thimble of lathe withstands in the hole of tailstock barrel 1, after first car becomes Φ 16 oblate, and cutting thread again.

2, Fig. 2 is tailstock barrel 1 a structure schematic diagram, and Fig. 3 is the left view of Fig. 2.Tailstock barrel 1 is to form with metal material processing, in the workpiece inverted draw cut of the end insertion 8 * 15 of workpiece 4, the thimble of lathe is not directly withstood on the workpiece, plays the effect of top tight workpiece.

3, Fig. 4 is chuck 2 structural representations, and Fig. 5 is Fig. 4 left view, and chuck available metal or nonmetallic materials process, and the other end of workpiece 4 passes the wide groove of 8mm, and workpiece is on the chuck central shaft.Size Φ D and H can decide as required, and this example is Φ D=Φ 100mm, H=30mm.

4, pin 3 sectional dimensions are 8 * H, are used to insert the notch of Fig. 4, and three-jaw chuck one pawl by lathe is clipped in the pin position and workpiece is held out against fixing.

Claims

1, a kind of oblate insulation blanket stud turning clamp, it is characterized in that being made up of tailstock barrel, chuck, pin, tailstock barrel one end has centre hole, and the tailstock barrel other end has the workpiece inverted draw cut, chuck has the workpiece groove of a mistake central shaft, and pin inserts in the workpiece groove of chuck.
