Abstract

A boring clamp used for processing circular holes of a double-hole positioning plate comprises a base plate and a scale division rotating disc mounted on the base plate. The scale division rotating disc is provided with a scale division positioning mechanism. The scale division positioning mechanism comprises a positioning rod, a connection seat, a spring, and bolts. The connection seat is fixed on the scale division rotating disc through the three uniformly-distributed bolts. The middle part of the positioning rod is provided with a chuck. The connection seat is provided with a hollow convex cavity. The chuck is arranged inside the convex cavity and fitted with the convex cavity. The spring is also arranged inside the convex cavity, and one end of the spring is in contact with the lower end of the chuck while the other end of the spring is in contact with the upper surface of the scale division rotating disc. According to the clamp, by virtue of using the scale division positioning mechanism for boring the ''double long holes'' of the double-hole positioning plate at symmetrical positions, the processing procession and the hole-to-hole parallelism of the ''double long holes'' of the double-hole positioning plate are ensured. According to practical usage, the boring clamp is excellent in effect; the boring clamp solves the production problem and ensures the processing precision of the positioning plate; and at the same time, the boring clamp substantially increases the processing production efficiency of the double-hole positioning plate.

Description

A kind of for processing the boring clamp of diplopore location-plate circular hole
Technical field
The utility model relates to jig field, relates in particular to a kind of for processing the boring clamp of diplopore location-plate circular hole.
Background technology
Diplopore location-plate (as shown in Figure 1) is that I take charge of an important spare part on certain type product, two parallel holes on it are long, requirement on machining accuracy is high, beginning utilizes circular table on normal horizontal miller, pressing plate, bolt is installed workpiece and is carried out lockhole processing, but in the parallel slotted hole process of boring two, be difficult to even cannot solve the accuracy of form and position of drawing requirement, in addition the effect that circular table is subject to cutting force easily produces loosening afterwards, while causing batch Boring, quality is unstable, thereby cause production efficiency low (each class can only process 15-20 part), obviously be to complete the product parts production and processing with some in this way.Also attempted in addition workpiece to be arranged on the knife rest of engine lathe, effect is also very undesirable.The lockhole working (machining) efficiency of these two kinds of processing methods all lower, quality is unstable.Processing method with " routine " on normal horizontal miller, engine lathe is carried out Boring to " the double slotted hole " of diplopore location-plate part, is all difficult to guarantee part crudy, also cannot complete monthly production task.In order to raise the efficiency, guarantee the stability of converted products quality and complete monthly production task, must a kind of novel frock clamp of design.
Utility model content
The utility model is for the deficiency of above-mentioned technology, provide a kind of for processing the boring clamp of diplopore location-plate circular hole, this fixture has solved due to the impact of factors such as " transpositions " " the double slotted hole " of diplopore location-plate part has been carried out to the impact that Boring causes, this fixture is by dividing and positioning mechanism " double-row hole " of boring diplopore location-plate part in symmetric position, thereby guaranteed the machining accuracy of diplopore location-plate part " double-row hole " and the depth of parallelism between the system of hole.Through reality, use, effect is rather good, has both solved a production difficult problem, has guaranteed the machining accuracy of part, has increased substantially the processing efficiency of diplopore location-plate part simultaneously.
The purpose of this utility model is achieved through the following technical solutions:
For processing a boring clamp for diplopore location-plate circular hole, comprise base plate and be installed on the indexing rotary table on base plate, it is characterized in that: on described indexing rotary table, be provided with dividing and positioning mechanism.
Above-mentioned dividing and positioning mechanism comprises backstay, Connection Block, spring and bolt, described Connection Block is bolted on indexing rotary table by three of evenly arranging, and described backstay middle part is provided with chuck, described Connection Block is provided with the protruding cavity of hollow, chuck is placed in protruding inside cavity, coordinates with protruding cavity, and described spring is also settled protruding inside cavity, end in contact on its one end and chuck, one end contacts with protruding chamber is inner.
Above-mentioned base plate lower end is provided with guide pad, and the effect of guide pad setting is to facilitate base plate to install on lathe, and described indexing rotary table lower end is provided with boss, is provided with the through hole that runs through indexing rotary table on boss, and boss matches with locating hole on base plate.
Thereby this fixture adopts operation principle of centrality, on milling machine, the parallel slotted hole one-time positioning of four stations of diplopore location-plate part is completed to installation have been reduced location, has proofreaied and correct the crudy that equal error has been guaranteed diplopore location-plate two parallel slotted holes.The principle of this fixture is mainly:
The first, utilize dividing and positioning mechanism carry out accurate calibration location make indexing rotary table in " rotations " process, guarantee alignment pin can be with two " special " on base plate thus dowel hole accurately coordinate the depth of parallelism of assurance diplopore location-plate part two parallel slotted holes.
The second, by accurately " location " control of dial gauge, thereby make the longitudinal workbench of milling machine can accurately move 50 millimeters of " centre-to-centre spacing " that guarantee two holes.
Thereby three, utilize the extension elongation that cutter stretches out, the interior hexagonal of indentation fine setting is accurately adjusted cutter above thorax knife rest to guarantee that the dimensional accuracy of being cut circular hole by thorax meets the requirement that drawing is stipulated.
The beneficial effects of the utility model are:
This fixture is processed by carry out the boring of two parallel holes on normal horizontal miller, and physical dimension, the accuracy of form and position and the surface roughness of four stations of diplopore location-plate part of institute's boring have all reached Design Requirement Drawing; Working (machining) efficiency is compared (plain-milling machine) processing and has been improved 2-4 doubly with conventional method, and solved diplopore location-plate part and be difficult in perpendicularity, the depth of parallelism of boring process mesopore the phenomenon guaranteeing, diplopore location-plate part " bore hole " crudy is better, working (machining) efficiency significantly improves, and has met product instructions for use.
