Abstract
The utility model discloses an inner bore positioning clamp, which comprises a fixed plate, wherein the fixed plate is provided with a working face which is provided with a positioning ring, the positioning ring is internally provided with a clip, a clamping space is formed between the positioning ring and the clip, a pull column is arranged in the clip, the lower part of the pull column is connected with a connecting rod, and the clip is internally provided with a bevel opening part. A workpiece to be machined is placed in the clamping space, after the pull column moves downwards, the clip outwards extrudes an inner bore of the workpiece to be machined, so that the inner bore is positioned. The inner bore positioning clamp has the advantages of convenience for clamping and positioning and high efficiency, two functions of positioning and clamping can be fulfilled at the same time by the outward extrusion of the clip, so that a product can be firmly and stably positioned in the clamping space to facilitate the subsequent machining of the product, and thus the machining precision and quality are guaranteed.
Description
Technical field
The utility model belongs to the tooling device technical field, relates in particular to a kind of endoporus positioning fixture.
Background technology
On machine tool during processing end cap or cylinder body, to be processed shape and size precision etc. are extremely important, the excessive and too small assembling that all can influence with other parts of the accessory size that is processed.Lathe needs through positioning fixture with the processed product location tightly, so that cutter carries out fine finishining to it when fine finishining end cap or cylinder body; Therefore the quality of positioning fixture design is related to be processed the quality and the problem of working (machining) efficiency; The shortcoming that existing positioning fixture exists is: it is not firm to locate, and complicated operation has had a strong impact on machining accuracy and quality; The processing time consuming effort, and percent defective is high.
Summary of the invention
The utility model technical problem to be solved is the present situation to prior art, and a kind of endoporus positioning fixture is provided, and it can realize locating and clamping two kinds of functions simultaneously, and is simple in structure, clamps the location conveniently, improves machining accuracy and quality.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of endoporus positioning fixture, comprise fixed head, and on the described fixed head working face is set; On the described working face locating ring is set, cartridge clip is set in the locating ring, form between described locating ring and the cartridge clip and clamp the space; In cartridge clip, be provided with stay column; To be processed be placed on clamp in the space, after stay column moves downward, make cartridge clip outwards push the endoporus of workpiece to be machined, thereby carry out the endoporus location.
For optimizing such scheme, the measure that the utility model is taked comprises:
In above-mentioned a kind of endoporus positioning fixture, in the described cartridge clip peristome is set, described peristome is tilted mouth shape.After stay column moves downward, just make the head of stay column outwards push cartridge clip like this, clamp to be processed endoporus thereby cartridge clip is outwards pushed.
In above-mentioned a kind of endoporus positioning fixture, described stay column bottom connects connecting rod, and is more more convenient when the pulling stay column carries out the endoporus location like this.
Compared with prior art; It is convenient that the advantage of the utility model is to clamp the location, and efficient is high, outwards pushes through cartridge clip; Can realize the location simultaneously and clamp two kinds of functions; Thereby position securely clamping the place, space product is stable,, guaranteed machining accuracy and quality so that next step is processed product.
Description of drawings
Fig. 1 is the structural representation of the endoporus positioning fixture of utility model.
Fig. 2 is the perspective view of the endoporus positioning fixture of the utility model.
Reference numeral: fixed head 1, connecting rod 2, stay column 3, cartridge clip 4, locating ring 5, to be processed 6.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As depicted in figs. 1 and 2, the endoporus positioning fixture of the utility model comprises fixed head 1; On the described fixed head 1 working face is set, locating ring 5 is set on the described working face, cartridge clip 4 is set in the locating ring 5; Form between described locating ring 5 and the cartridge clip 4 and clamp the space, in cartridge clip 4, be provided with stay column 3, to be processed 6 is placed on the locating ring 5; After stay column 3 moves downward, make cartridge clip 4 outwards push to be processed 6 endoporus, thereby carry out the endoporus location.
In the described cartridge clip 4 peristome is set, described peristome is tilted mouth shape.After stay column 3 moves downward, just make the head of stay column 3 outwards push cartridge clip 4 like this, thereby make cartridge clip 4 outwards push the endoporus of clamping to be processed 6, for more more convenient when pulling stay column 3 carries out the endoporus location, described stay column connects connecting rod 23 times.
Specific embodiment described herein only is that the utility model is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the defined scope of the utility model.
