Abstract

The utility model discloses a drill hole die for drilling shaft holes of a hinge. The drill hole die comprises a baffle (1), a drill body (2), a drill plate (4), an end head drill plate (5), a bearing plate (6) and a set screw (7), wherein the drill plate (4) and the end head drill plate (5) are fastened on the drill body (2); one side of the drill plate (4) and the end head drill plate (5) is made into a group of concave-convex teeth engaged with grooves and bumps on hinge-like parts; lead holes are arranged on the group of concave-convex teeth; and a drill bit starts to drill from the lead hole of the end head drill plate (5) while drilling a shaft hole. By adopting module replaceable manner of the drill plate, the drill hole die may adopt a plurality of drill plates (4) based on the specific length of hinge-like parts to achieve combination positioning, thereby greatly improving the design of drill hole die and manufacture progress. The drill hole die is suitable for drilling holes of hinge-like parts of various lengths, one-way drilling hole or two-way drilling holes and can ensure the hole accuracy and coaxiality.

Description

A kind of boring mould that bores system hinge leaf shaft hole

Technical field

The utility model relates to a kind of boring mould that bores system hinge leaf shaft hole.

Background technology

The groove and the projection of two hinge leaf of hinge leaf class part are meshing with each other, and rotate around common rotating shaft, and hinge leaf class part is generally plate shaped, and length scale does not wait, from 200mm to 1000mm more than, its shaft hole is generally about Φ 4mm.The processing of this elongated hole adopts deep hole equipment to process at present abroad, and domestic use drilling machine or pneumatic drill are processed, the method that adopts two ends boring to connect, the hole precision that often gets out is not high, axiality can not reach requirement, the work in-process difficult quality guarantee is when shaft hole is very long even can't process.

Summary of the invention:

The technical problems to be solved in the utility model is to provide a kind of boring mould that bores system hinge leaf shaft hole, when adopting the method for two ends boring connection, the aperture can not misplace, and when the hinge leaf class part of processing different length, can use the boring mould of this kind structure.

For solving the problems of the technologies described above, the utility model provides a kind of boring mould that bores system hinge leaf shaft hole, comprise: baffle plate, the drill jig main body, bushing plate, the termination bushing plate, backing plate and holding screw, described bushing plate is fastened on the drill jig main body by two pins and a screw location, one side of bushing plate and termination bushing plate manufacture with hinge leaf class part on groove and the intermeshing one group of concavo-convex profile of tooth of projection, on the concavo-convex profile of tooth of this group, have the bullport of perforation, length according to hinge leaf class part, some bushing plates and a termination bushing plate are set, described baffle plate and backing plate are fixed tightly in the two ends of drill jig main body respectively, the width of baffle plate and backing plate is greater than the width of drill jig main body, stablize and have a screwed hole on the backing plate, holding screw can rotate advance and retreat in the screwed hole of backing plate, the one side of described drill jig main body is made step surface, have some groups of pin holes and screwed hole on the lower step surface, in order to fixedly bushing plate and termination bushing plate, also make some through holes and groove on the lower in addition step surface, during use, hinge leaf class part lies on the drill jig main body plane, clamp two ends by the holding screw on baffle plate and the backing plate, with general pressing plate or Pressing clamp hinge leaf class part is pressed on the drill jig main body, when boring shaft hole, drill bit begins the system of boring from termination bushing plate bullport.

The utility model has following good effect than prior art.Bushing plate adopts the interchangeable mode of modular, can adopt some bushing plates to carry out integrated positioning according to the length of concrete part, can improve the design and the manufacturing progress of boring mould greatly, adapt to the boring of all lengths hinge leaf class part, unidirectional boring or two ends boring are connected and all can be guaranteed hole precision and axiality.

The specific embodiment

Below in conjunction with embodiment the utility model is further described.

Fig. 1 shows a kind of hinge leaf class part, is " L " type, has the shaft hole that runs through on fluted limit.

Bushing plate 4 and termination bushing plate 5 are fastened on the drill jig main body 2 by two pins and a screw location among Fig. 2, one side of bushing plate 4 and bushing plate 5 manufacture with hinge leaf class part on groove and the intermeshing one group of concavo-convex profile of tooth of projection, on the concavo-convex profile of tooth of this group, have the bullport of perforation, length according to hinge leaf class part 3, some bushing plates 4 and a termination bushing plate 5 are set, described baffle plate 1 and backing plate 6 are fixed tightly in the two ends of drill jig main body 2 respectively, the width of baffle plate 1 and backing plate 6 is greater than the width of drill jig main body 2,6 have a screwed hole on the backing plate, holding screw 7 can rotate advance and retreat in the screwed hole of backing plate, during use, hinge leaf class part 3 lies on drill jig main body 2 planes, utilize the location, the inboard baseplane of groove on the bushing plate 4, clamp two ends by the holding screw on baffle plate 1 and the backing plate 67, by general pressing plate or Pressing clamp hinge leaf class part 3 and drill jig main body 2 are compressed together, when boring shaft hole, begin the system of boring from the bullport of termination bushing plate 5.

Among Fig. 3, the drill jig main body adopts the tool steel manufacturing, both ends of the surface have three screwed holes and two pin holes are used for fixing baffle plate and backing plate, the one side of drill jig main body is made step surface, when hinge leaf class part lies in two step surface intersections, hinge leaf class part shaft hole limit is unsettled, have some groups of pin holes and screwed hole on the lower step surface, in order to fixedly bushing plate and termination bushing plate, also make some tapped through holes and groove on the lower in addition step surface, compress the spacing of the pressing plate of product parts and pressing plate in order to installation.As clamp is installed then on main body, is made the respective threads installing hole.

Fig. 4 and Fig. 5 are the stereograms of bushing plate and front end bushing plate.
