Description

Scrap iron prevention chuck for lathe

Technical Field

The utility model relates to a prevent iron fillings chuck for lathe, especially a chuck that iron fillings got into that lathe was used can prevent.

Background

At present, the chuck ubiquitous that current lathe was used iron fillings under the rotatory state of work when the chuck is nearer from the work piece get into the chuck easily, lead to the chuck jack catch can not advance and retreat, must lift the jack catch off by force, clearance jack catch, slide and gear, the clearance wastes time and energy, and intensity of labour is big, influences work efficiency, because iron fillings get into cause mechanical contact part wearing and tearing in the chuck, have reduced the life of spare part.

Disclosure of Invention

An object of the utility model is to overcome above-mentioned shortcoming, provide a prevent iron fillings chuck for lathe, it has mainly solved the chuck ubiquitous chuck that current lathe was used and has got into the chuck from the work piece work rotation state down iron fillings easily in, lead to the chuck jack catch can not advance and retreat, must lift the jack catch off by force, clearance jack catch, slide and gear, because iron fillings get into cause mechanical contact position wearing and tearing in the chuck, have reduced spare part's life scheduling problem. The utility model aims at realizing like this, a prevent iron fillings chuck for lathe by: the device comprises a shell, a clamping jaw, a movable baffle, a slideway, a groove, a spring, a mounting hole, an inclined plane groove, a chuck hole, a cover plate, a bolt, a tension spring, a protecting sleeve, a widening groove, a bevel gear and a bracket. The clamping jaw is three, it is installed on body through the bevel gear, there are bevel grooves on the clamping jaw, the bevel gear is installed on body, it is engaged with bevel gear, one end of the clamping jaw is equipped with the lag, the lag is clung to the edge of the chuck hole, both sides of rear end of the clamping jaw have widening grooves, the tension spring is installed in widening groove, the front end of the body has slideway, it is on the edge of the chuck hole, the movable baffle is installed in slideway, it can slide horizontally, the movable baffle is equipped with the support, the lower end of the slideway has grooves, the grooves are parallel to slideway, the spring is installed in the groove, the cover plate is connected with body through the bolt, there are mounting holes on the body. The slide way, the movable baffle and the protective sleeve are additionally arranged in the chuck, so that scrap iron in a working rotation state when the chuck is close to a workpiece can be blocked and cannot enter the chuck, chuck jaws can advance and retreat flexibly, the workpiece can be conveniently detached, the operation efficiency is high, the slide way, the gears and the jaws do not need to be cleaned frequently, the abrasion of mechanical contact parts is reduced, and the service life of parts is prolonged.

Detailed Description

The best embodiment of the invention is described in detail below with reference to the accompanying drawings, and the scrap iron prevention chuck for a lathe comprises: the device comprises a shell 1, a jaw 2, a movable baffle 3, a slideway 4, a groove 5, a spring 6, a mounting hole 7, an inclined plane groove 8, a chuck hole 9, a cover plate 10, a bolt 11, a tension spring 12, a protective sleeve 13, a widening groove 14, a bevel gear 15, a bevel gear 16 and a support 17. The three clamping jaws 2 are arranged on a shell 1 through a bevel gear 16, the clamping jaws 2 are provided with bevel grooves 8, a bevel gear 15 is arranged on the shell 1 and is meshed with the bevel gear 16, one end of each clamping jaw 2 is provided with a protective sleeve 13, the protective sleeves 13 are tightly attached to the edge of a chuck hole 9, two sides of the rear end of each clamping jaw 2 are provided with widening grooves 14, a tension spring 12 is arranged in each widening groove 14, the front end of the shell 1 is provided with a slide way 4 which is arranged on the edge of the chuck hole 9, a movable baffle 3 is arranged in each slide way 4 and can slide horizontally, a support 17 is arranged on each movable baffle 3, the lower end of each slide way 4 is provided with a groove 5, each groove 5 is parallel to each slide way 4, a spring 6 is arranged in each groove 5, a cover plate 10 is connected with the shell 1 through a bolt 11, the shell 1 is provided with a mounting hole 7.

When the clamping device works, a T-shaped spanner is inserted into a square hole in the outer side of the bevel gear 15, the bevel gear 15 drives the bevel gear 16 to rotate, the clamping jaw 2 is driven to perform centripetal and centrifugal movement to clamp a workpiece, when the clamping jaw 2 performs centrifugal movement outwards, the movable baffle 3 moves towards the left side on the slide way 4 through the elastic force of the spring 6, the protective sleeve 13 moves outwards under the action of the tension spring 12 and stops moving when moving to the edge of the chuck hole 9, the scrap iron can be blocked in the chuck hole 9 by the movable baffle 3, so that the scrap iron does not enter the chuck, when the clamping jaw 2 performs centripetal movement inwards, the movable baffle 3 is forced to move rightwards through the inclined plane groove 8 by the clamping jaw 2, the spring 6 returns, when the radial movement continues to contact the protective sleeve 13, the protective sleeve 13 drives the tension spring 12 to stretch, and the meshing part of the clamping jaw 2 and the bevel gear 16 is protected.
