Abstract

The utility model discloses a drilling jig of an excircle surface of a cylindrical workpiece. The jig comprises a jig body. A working chamber is disposed along the axle through the jig body and in the middle part of the jig body. The left end surface of the jig body is provided with a stop block. The right end of the working chamber is provided with inner thread. The right end of the jig body is connected with a tightening nut through the inner thread. The two sides of the outer wall of the jig body are provided with symmetrical drilling holes. The lower ends of the drilling holes are inserted into the jig body. The center of the jig body is provided with a positioning hole. The jig achieves fixation of a cylindrical workpiece by using a few elements. The jig is simple in structure, low in manufacture cost, and convenient to operate, and then improves drilling efficiency. The jig is not provided with a pressing block, so that conditions that a pressing block is applied with a overlarge downward pressing force to cause partial microscale deformation to influence quality of a drilled product cannot occur, and then certified product quality is effectively improved, a plurality of substandard products and waste products are eliminated, and production cost is reduced.

Description

A kind of boring grab of excircle of cylindrical workpiece face
Technical field
The utility model relates to a kind of boring grab of excircle of cylindrical workpiece face, belongs to Machining Technology field.
Background technology
To axle class, tubings etc. have cylindrical peripheral face workpiece while carrying out machined, conventionally need on pipe or axle, process and axially perpendicular hole, boring be all generally directly by clamping workpiece on lathe, and then carry out Drilling operation with drill bit, but because cylindrical work is difficult for clamping, process easily moves axially or circumferentially rolls, make boring location inaccurate, need repeatedly adjust bore position, and then make boring consuming time longer, cause operating efficiency to decline, and also can increase artificial labour intensity, simultaneously because borehole accuracy is low, crudy is wayward, also can cause the appearance of a large amount of substandard products and waste product, processing cost is higher.
Chinese patent ZL201310101793.1 is disclosed has the drilling equipment that cylindrical peripheral face Workpiece boring is used, comprise body, in body, be provided with along left and right directions and extend and for the workpiece locating hole of corresponding to be processed plug-in mounting, in described workpiece locating hole, be provided with for the two ends block with to be processed spacing coordinate first, the second axial limiting mechanism, described first, at least one position-limit mechanism in the second axial limiting mechanism comprise have axial displacement regulated quantity for to be processed top friction tight push rod, on described body surface in described first, between two axial limiting mechanisms, offer the breach and the drilling tool hole that communicate with described workpiece locating hole, in described breach, be provided with radial positioning mechanism, described radial drive mechanism comprises the compact heap with radial displacement regulated quantity, described compact heap has near one end of described workpiece locating hole the seal face that is adjacent to stop to be processed circumferential rotation for the periphery cambered surface adaptation with corresponding to be processed.Though this scheme is holding cylindrical workpiece effectively, prevent that workpiece from rotating or moving axially, be convenient to Drilling operation, part is more, and assembling and operation need expend the long period; And compact heap is for radial compaction workpiece, and dynamics is excessive, can cause workpiece that micro-deformation occurs, and affects end product quality, and dynamics does not have not again the fixed effect of anti-rotation.
Utility model content
In order to solve the problems of the technologies described above, the utility model aims to provide a kind of simple in structure, boring grab of assembling the excircle of cylindrical workpiece face quick, simple to operate, with low cost, drilling efficiency is high.
The utility model is achieved by the following technical solution:
A kind of boring grab of excircle of cylindrical workpiece face, comprise that middle part has the body of working chamber along axis entire body, body left side is connected with limited block, working chamber right-hand member is provided with internal thread, body right-hand member is connected with fastening nut by internal thread, described body outer wall both sides are provided with the drill bushing being arranged symmetrically with, and insert in body drill bushing lower end, and drill bushing center has locating hole.
Described limited block middle part has the through hole coaxial with working chamber, by this through hole, is connected with and is moved back part pin.
Described drill bushing top is provided with steady pin, and alignment pin is perpendicular to body surface and insert in body.
Described limited block by screw fastening in body left side.
On described fastening nut, handle is installed.
Described screw has four at least.
The beneficial effects of the utility model are:
Compared with prior art, the boring grab of the excircle of cylindrical workpiece face that the utility model provides, only needs can complete the fixing, simple in structure of cylindrical work by a small amount of part, and low cost of manufacture is easy to operate, and then has promoted drilling efficiency; Cancelled the use of compact heap simultaneously, there will not be compact heap downforce to spend and cause greatly local micro-deformation, the situation of the quality of finished product after impact boring, and then effectively promoted certified products quality, and avoid the appearance of a large amount of substandard products and waste product, reduced production cost.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 1;
In figure: 1-moves back part pin, 2-screw, 3-limited block, 4-drill bushing, 5-steady pin, 6-body, 7-fastening nut, 8-handle, 9-working chamber, 10-locating hole.
The specific embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described further, but described in desired protection domain is not limited to;
As shown in Figure 1, the boring grab of the excircle of cylindrical workpiece face that the utility model provides, comprise that middle part has the body 6 of working chamber 9 along axis entire body, body 6 left sides are connected with limited block 3, working chamber 9 right-hand members are provided with internal thread, and body 6 right-hand members are connected with fastening nut 7 by internal thread, and described body 6 outer wall both sides are provided with the drill bushing 4 being arranged symmetrically with, insert in body 6 drill bushing 4 lower ends, and drill bushing 4 centers have locating hole 10.
In order to meet boring, finish rapidly and efficiently exiting of rear workpiece, described limited block 3 middle parts have the through hole coaxial with working chamber 9, by this through hole, are connected with and are moved back part pin 1.
In order to prevent that drill bushing 4 from together rotating with drill bit, affect precision, described drill bushing 4 tops are provided with steady pin 5, and alignment pin 5 is perpendicular to body 6 surface and insert in body 6.
Described limited block 3 is fastened on body 6 left sides by screw 2, has and processes simple, stable connection, advantage for convenience detach.
In order to save manpower, be convenient to screwing fast of fastening nut 7, on described fastening nut 7, handle 8 is installed.
