Abstract
The invention relates to a clamp special for machining a steel plate spring lifting lug hole. The clamp comprises a power source part, a middle mechanism and a clamping executing mechanism. The power source part is composed of a gear shaft and a rack. The middle mechanism is composed of guide pillars. The clamping executing mechanism is composed of a V-shaped pressing block. A V-shaped block and a positioning plate are fixed to a clamp body through a bolt. A drill sleeve is assembled to a drill plate, the V-shaped pressing block has the function of a lining of the drill sleeve, the drill sleeve is arranged on the V-shaped pressing block, and the whole drill plate is arranged on the two guide pillars. The rack is engaged with a gear on the gear shaft through the guide pillars, and a gear and rack mechanism drives the drill plate to move vertically. The clamp special for machining the steel plate spring lifting lug hole has the beneficial effects that the gear and the rack are used for driving the V-shaped pressing block to achieve centering clamping of a part, clamping is reliable, operation is fast and convenient, and the labor intensity of workers can be lowered; and meanwhile, the V-shaped block is adopted for positioning, the positioning precision is high, and the requirement for part machining quality is met.
Description
Technical field
The present invention relates 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.Finger aims at certain road of a certain workpiece
Operation and the fixture that specially designs.Compact conformation is characterized in, operation is rapid, convenient, 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, is not affected by workman's technical merit that its machining accuracy is high and stable by fixture.
The content of the invention
The purpose of the present invention is to overcome deficiency of the prior art, there is provided a kind of reliability is high, it is ensured that machining accuracy,
Mitigate the spring hanger hole machined special fixture of the labour intensity of workman simultaneously.
The purpose of the present invention 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 tooth bar；Intermediary agency is by being oriented to
Post is constituted；Perform clamp system to be made up of V-type briquetting；V-block and location-plate are bolted on clamp body；Drill bushing is assembled
On lamina membranacea is bored, and V-type briquetting has the bushing effect of drill bushing concurrently, and drill bushing is mounted on V-type briquetting, and is entirely bored lamina membranacea and be mounted in two
In lead column；Tooth bar is realized being engaged with gear shaft gear by lead column, and pinion and rack drives and moved down on brill lamina membranacea
It is dynamic.
The invention has the beneficial effects as follows:This patent drives V-type briquetting to realize that the centering to part is clamped using rack-and-pinion,
It is rapid and convenient with reliable clamping, operation, the labour intensity of workman can be mitigated.Positioned using V-block simultaneously, positioning precision
It is higher, meet the requirement of part crudy.

Description of reference numerals：Clamp body 1, bolt 2, location-plate 3, V-block 4, lead column 5, V-type briquetting 6, hanger 7, support
Plate 8, bolt 9, drill bushing 10, bore lamina membranacea 11, handle 12, gear shaft 13, support base 14, ring washer 15, axle 16, tooth bar 17.
Specific embodiment
The present invention is described further with reference to embodiment.The explanation of following embodiments is only intended to help and understands this
Invention.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, also
Some improvement and modification can be carried out to the present invention, these are improved and modification also falls into the protection domain of the claims in the present invention
It is interior.
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 tooth bar 17；Intermediary agency is made up of lead column 5；
Perform clamp system 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 lamina membranacea 11 is bored, and V-type briquetting 6 has the bushing effect of drill bushing 10 concurrently, and drill bushing 10 is mounted on V-type briquetting 6, and entirely bores lamina membranacea
11 are mounted in two lead columns 5；Tooth bar 17 is realized being engaged with gear shaft 13 gear by lead column 5, pinion and rack
Brill lamina membranacea 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 and cylindrical for positioning datum, in the case where location-plate 3 and V-block 4 are acted on five point locations are realized.Gripper shoe 8 plays pre-determined bit effect.Turn
Fixed handle, drives brill lamina membranacea to move down by pinion and rack, realizes that centering is clamped using V-type briquetting.First, part processing
In, to realize that part occupies correct position in fixture, it is ensured that positioning precision, just can guarantee that the machining accuracy of part.Workpiece
Installation positioning on fixture is realized by location-plate 3 and V-block 4, is calculated by analysis of Positioning Error, this kind of positioning mode is complete
The requirement of positioning precision can be met entirely；Its is secondary to realize the clamping to part on fixture, to ensure process in part
The correct position occupied does not change, it should be noted that in clamping process, it is impossible to which the position for causing part changes, otherwise
The meaning of positioning is just lost, actuating unit is that rack-and-pinion drives V-type briquetting 6 to realize the clamping to workpiece by lead column 5.
