Abstract

The utility model relates to a wire hole clamp for an automobile exhaust pipe. The wire hole clamp comprises a base, a base plate mounted on the base and a supporting rod fixed on the base plate, wherein a driving device is arranged on the base plate; the top of the driving device is hinged to a pressing plate; the pressing plate is hinged to the supporting rod in a rotatable manner; the top of the pressing plate is in threaded connection with a pressing block; scale slots are formed in the base; a positioning block is mounted in a sliding chute of the base; a handle is arranged on the positioning block. The wire hole clamp is reasonable in design and simple in structure; when the exhaust pipe is put into the positioning block, the positioning block is hydraulically driven to move towards the direction of the pressing plate; the top of the driving device acts on one side of the pressing plate to drive the pressing block to move downwards to fix the exhaust pipe; after the processing is finished, the pressing block is automatically released; the wire hole clamp has automation degree and can realize automatic material loading and unloading and pressing and positioning of materials; in addition, the contact area is large enough to realize uniform stressing, and damage to the exhaust pipe during processing is reduced.

Description

A kind of automobile exhaust pipe thread hole fixture

Technical field

The utility model relates to auto parts manufacture field, relates in particular to a kind of automobile exhaust pipe thread hole fixture.

Background technology

Blast pipe is a vitals of automobile, due to its out-of-shape, in process, be difficult to clamping, at present, in the prior art, the general technical barriers such as processing difficulties, inefficiency that partially exist of fixture that blast pipe is processed, reason is, the complex contour of blast pipe, and blast pipe is being added to man-hour, and be all blank, be difficult to clamp, if want, clamp to adopt and a plurality of clamping points are set clamp, add more auxiliary workpiece, but can exist so again clamping point too many, cause blast pipe to be deformed and do not reach technique needs.When output is little, fixture is generally all made into manual, adopts hydraulic pressure or air-actuated jaw when output promotes.Manual is all generally single-piece work, and the clamping workpiece time is long, and machining center all needs tool changing adding every of man-hour, and working (machining) efficiency is lower.The general tube wall of blast pipe is thinner, when fixture positions fixedly, and the little damage that easily causes tube wall of contact area.

Utility model content

The utility model, in order to overcome deficiency of the prior art, provides a kind of automobile exhaust pipe thread hole fixture.

The utility model is to be achieved through the following technical solutions:

A kind of automobile exhaust pipe thread hole fixture, comprise base, be arranged on base plate on described base, be fixed on the support bar on described base plate, described base plate is provided with drive unit, the top of described drive unit is hinged with pressing plate, the rotation of described pressing plate and described support bar is hinged, the top of the described pressing plate briquetting that has been threaded, and described base is provided with scale groove, in the chute of described base, locating piece is installed, described locating piece is provided with handle.

As optimal technical scheme of the present utility model, described drive unit is fluid pressure drive device.

As optimal technical scheme of the present utility model, the bottom of described briquetting is circular arc.

As optimal technical scheme of the present utility model, described handle is provided with reticulate pattern.

Compared with prior art, the beneficial effects of the utility model are: the utility model is reasonable in design, simple in structure, among blast pipe is put into locating piece, hydraulic-driven locating piece moves to pressing plate direction, the top of drive unit acts on pressing plate one side drive briquetting and moves downward, blast pipe is fixed, machining rear briquetting unclamps automatically, there is automaticity, the compression location that can realize automatic loading/unloading and material, while contact area makes greatly stressed even, reduces the damage to blast pipe in processing.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

In figure: 1-base; 2-locating piece; 3-briquetting; 4-support bar; 5-pressing plate; 6-drive unit; 7-base plate; 8-scale groove; 9-handle.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.

Described a kind of automobile exhaust pipe thread hole fixture, comprise base 1, be arranged on base plate 7 on described base 1, be fixed on the support bar 4 on described base plate 7, described base plate 7 is provided with drive unit 6, the top of described drive unit 6 is hinged with pressing plate 5, described pressing plate 5 is hinged with described support bar 4 rotations, the top of described pressing plate 5 briquetting 3 that has been threaded, and described base 1 is provided with scale groove 8, locating piece 2 is installed in the chute of described base 1, and described locating piece 2 is provided with handle 9.Described drive unit 6 is fluid pressure drive device.The bottom of described briquetting 3 is circular arc.The movement position that described scale groove 8 has been realized locating piece is visual, applicable small lot batch manufacture.Described handle 9 can be realized manual slide and the rear manually locking function in location, among blast pipe is put into locating piece 2, hydraulic-driven locating piece 2 is to pressing plate 5 direction motions, the top of drive unit acts on pressing plate 5 one side drive briquettings 3 and moves downward, and blast pipe is fixed, and machines rear briquetting 3 and automatically unclamps, there is automaticity, the compression location that can realize automatic loading/unloading and material, while contact area makes greatly stressed even, reduces the damage to blast pipe in processing.

Described handle 9 is provided with reticulate pattern, convenient easy to operate during manual operation.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
