The tension device has the advantages of reasonable structure and high reliability, and the tension and loosening structure of the expansion sleeve is realized through the pull rod, so that the cost of the clamp is reduced, and the processing efficiency is improved.

Description

Novel hobbing clamp

Technical Field

The utility model relates to a derailleur assembly field of car class, specific novel a hobbing clamp that says so.

Background

The transmission is a key component in an automobile power transmission system, the first shaft is an important component for connecting the transmission and an engine, and therefore the transmission precision of the whole automobile is seriously influenced by the product quality of the first shaft. The expansion sleeve type clamp used in the existing machining process is provided with a taper on a body, and the expansion sleeve is expanded by pulling a pull rod downwards, so that a tension workpiece is machined. After the workpiece is machined, the support rod is jacked through the pull rod so as to jack the expansion sleeve upwards, the expansion sleeve is loosened, and an operator takes down the workpiece.

The disadvantages of the above structure are: when in processing, the support rod is thin and is often bent, so that the expansion sleeve cannot be completely loosened, and the workpiece cannot be taken down. The support rod needs to be replaced irregularly, so that the replacement and adjustment time is long, the production is delayed, and the cost of the clamp is increased.

Disclosure of Invention

The utility model aims at providing a novel a hobbing clamp has rational in infrastructure and the high advantage of reliability, makes the cover that rises through the pull rod rise and tightly loosen's structure, has reduced the anchor clamps cost, has improved machining efficiency.

The technical implementation scheme of the invention is as follows:

the utility model provides a novel a hobbing clamp, includes that the piece that rises 1, spring coil 2, pull rod 3, body 5, anti-rotating screw 7, connect pole 8 and base 9, body 5 and base 9 connect through hexagonal socket head cap screw 6 in the second, connect pole 8 and base 9 and connect through anti-rotating screw 7, in pull rod 3 stretched into the round hole of body 5, the through-hole that first hexagonal socket head cap screw 4 passed on the body 5 supported at the spacing inslot of pull rod 3, pull rod 3 kept away from the one end that connects pole 8 has the tapering, the conical surface supports and leans on the piece that rises 1, the piece that rises 1 twines through spring coil 2 and ties up on body 5.

As a more excellent technical solution of the utility model: the pull rod 3 has 9 degrees of taper, and the expansion block 1 is expanded to achieve the effect of tensioning the workpiece by pulling the pull rod 3 downwards.

The beneficial effects are as follows:

a. the technical problems that the expansion sleeve cannot be completely loosened and a workpiece cannot be taken down due to bending caused by thin supporting rods when the traditional clamp is used are solved;

b. the supporting rod of the traditional clamp which needs to be replaced by a quick-wear part frequently is avoided, the cost is saved, the adjusting time is shortened, and the processing efficiency is improved.

c. Other structures of the hobbing clamp are not changed, and normal assembly and performance of other mechanisms are not influenced.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the utility model relates to a novel a hobbing clamp, including the piece 1 that rises, spring coil 2, pull rod 3, body 5, prevent changeing screw 7, connect pole 8 and base 9, body 5 and base 9 connect through second hexagon socket head cap screw 6, connect pole 8 and base 9 and connect through preventing changeing screw 7, in pull rod 3 stretched into the round hole of body 5, first hexagon socket head cap screw 4 passed the through-hole on the body 5 and supported at the spacing inslot of pull rod 3, there was the tapering one end that connects pole 8 was kept away from to pull rod 3, the conical surface supported and leans on the piece 1 that rises, the piece 1 that rises twines on body 5 through the spring coil. The base 9 is provided with a bolt hole, the connecting rod 8 corresponding to the bolt hole is provided with a limiting hole, the anti-rotation screw 7 is arranged in the bolt hole and is arranged in the limiting hole, and the diameter of the pull rod 3 far away from one end face of the connecting rod 8 is larger than that of the pull rod.

As shown in fig. 2, the body 5 of the conventional clamp is tapered, and the tension rod is pulled downwards to expand the expansion sleeve 1, so as to tension the workpiece for processing. After the workpiece is machined, the support rod is jacked through the pull rod so as to jack the expansion sleeve upwards, the expansion sleeve is loosened, and an operator takes down the workpiece.

The utility model discloses a 3 tapering of pull rod of anchor clamps take, make the cover 1 that rises to rise open through 3 pulldowns of pull rod to the tight work piece that rises is processed. After the workpiece is machined, the tension rod pushes upwards to loosen the expansion sleeve, and an operator takes down the workpiece. Other structures of the hobbing clamp are unchanged, normal assembly and performance of other mechanisms are not affected, product quality is guaranteed, meanwhile, the cost of the clamp is reduced, and machining efficiency is improved.
