Abstract
The utility model is related to a kind of spring hanger hole machined special fixture, including power source part, intermediary agency and execution clamp system；Power source part is made up of gear shaft and rack；Intermediary agency is made up of lead；Clamp system is performed to be made up of V-type briquetting；V-block and location-plate are bolted on clamp body；Drill bushing is assemblied on brill diaphragm plate, and V-type briquetting has the bushing effect of drill bushing concurrently, and drill bushing entirely bores diaphragm plate on two leads on V-type briquetting；Rack realizes and engaged with gear shaft gear that pinion and rack drives brill diaphragm plate to move up and down by lead.The beneficial effects of the utility model are:This patent drives V-type briquetting to realize that the centering to part is clamped using rack-and-pinion, with reliable clamping, operates rapidly and conveniently, can mitigate the labor intensity of workman.Simultaneously using V-block positioning, positioning precision is higher, meets the requirement of part crudy.
Description
Technical field
The utility model is related to a kind of fixture, more specifically, is related to a kind of spring hanger hole machined special fixture.
Background technology
Jig is to clamping workpiece and a kind of device of guiding cutter on lathe.Refer to certain road for aiming at a certain workpiece
Process and the fixture specially designed.Be characterized in compact conformation, operation is rapid, conveniently, it is laborsaving, it is ensured that higher processing essence
Degree and production efficiency.Installed using fixture, the mutual alignment between workpiece and lathe, cutter can be accurately determined, workpiece
Positional precision is ensured by fixture, is not influenceed by workman's technical merit, and its machining accuracy is high and stably.
Utility model content
The purpose of this utility model is to overcome of the prior art not enough high there is provided a kind of reliability, it is ensured that processing
Precision, while mitigating the spring hanger hole machined special fixture of the labor intensity of workman.
The purpose of this utility model is achieved through the following technical solutions:Spring hanger hole machined special fixture,
Including power source part, intermediary agency and execution clamp system；Power source part is made up of gear shaft and rack；Intermediary agency by
Lead is constituted；Clamp system is performed to be made up of V-type briquetting；V-block and location-plate are bolted on clamp body；Drill bushing
It is assemblied on brill diaphragm plate, and V-type briquetting has the bushing effect of drill bushing concurrently, drill bushing entirely bores diaphragm plate and is mounted on V-type briquetting
On two leads；Rack realizes and engaged with gear shaft gear that pinion and rack is driven on brill diaphragm plate by lead
Lower movement.
The beneficial effects of the utility model are:This patent drives V-type briquetting to realize the centering to part using rack-and-pinion
Clamp, with reliable clamping, operate rapidly and conveniently, the labor intensity of workman can be mitigated.It is fixed simultaneously using V-block positioning
Position precision is higher, meets the requirement of part crudy.

Embodiment
The utility model is described further with reference to embodiment.The explanation of following embodiments is only intended to help and managed
Solve the utility model.It should be pointed out that for those skilled in the art, not departing from the utility model principle
On the premise of, some improvement and modification can also be carried out to the utility model, these are improved and modification also falls into the utility model
In scope of the claims.
As shown in Figure 1 to Figure 3, the spring hanger hole machined special fixture of the present embodiment, including power source part, in
Between mechanism and perform clamp system；Power source part is made up of gear shaft 13 and rack 17；Intermediary agency is made up of lead 5；
Clamp system is performed to be made up of V-type briquetting 6；V-block 4 and location-plate 3 are bolted on clamp body 1；Drill bushing 10 is assembled
On diaphragm plate 11 is bored, and V-type briquetting 6 has the bushing effect of drill bushing 10 concurrently, and drill bushing 10 entirely bores diaphragm plate on V-type briquetting 6
11 on two leads 5；Rack 17 realized by lead 5 and engaged with gear shaft 13 gear, pinion and rack
Brill diaphragm plate 11 is driven to move up and down.
This fixture is mainly used in the lead plug in spring hanger hole.On upright drill, workpiece is with partEnd face
With it is cylindrical be positioning datum, realize five point locations in the case where location-plate 3 and V-block 4 are acted on.Supporting plate 8 plays pre-determined bit.Rotate
Handle, drives brill diaphragm plate to move down by pinion and rack, utilizes V-type briquetting to realize that centering is clamped.First, in part processing,
Realize that part occupies correct position in fixture, it is ensured that positioning precision, just can guarantee that the machining accuracy of part.Workpiece passes through
Location-plate 3 and V-block 4 realize the installation positioning on fixture, are calculated by analysis of Positioning Error, such a positioning method completely may be used
To meet the requirement of positioning precision；Its secondary clamping realized on fixture to part, to ensure that part occupies in process
Correct position do not change, it should be noted that in clamping process, it is impossible to cause the position of part to change, otherwise just lose
The meaning of positioning is gone, actuating unit is that rack-and-pinion drives V-type briquetting 6 to realize the clamping to workpiece by lead 5.
