Embodiment Construction

[0012] The present invention will be described in further detail below by means of specific embodiments:

[0013] The reference signs in the drawings of the description include: claw 1, lever 2, pin shaft 3, ejector pin 4, spring 5, cone 6, pull rod 7.

[0014] The embodiment is basically as figure 1 Shown: The pneumatic double-jaw chuck for tillage machine includes a base, jaw 1, positioning block, lever 2, cone 6 and pull rod 7, the base is hollow, and its right end is detachably connected to the machine tool spindle , There are two penetrating strip grooves on the outer edge of the left end of the base. The left end of the tie rod is connected to the cone. The size of the cone gradually decreases from left to right. There is a stepped hole in the cone. It is clamped at the stepped hole, the right end of the connector protrudes from the cone and is connected with a nut, which is convenient for installation and disassembly. The pull rod is clamped through the connector to fi...

Abstract

The invention discloses a pneumatic double-jaw chuck for mini-tillers. The pneumatic double-jaw chuck comprises a base, jaws, a positioning block, levers, a cone and a draw bar. The right end of the hollow base is detachably connected onto a spindle of a machine tool, two through strip-shaped grooves are formed in the outer edge of the left end of the base, the left end of the draw bar is connected with the cone, the cone is gradually diminished from the left to the right and is positioned in a middle cavity of the base, the middles of the levers are pivotally connected into the strip-shaped grooves, the jaws are connected to the left ends of the levers, the right ends of the levers extend into the middle cavity of the base and are butted onto the outer edge of the cone, the positioning block is positioned between the two levers and is arranged in the cavity of the base, and a positioning boss is arranged at the left end of the positioning block. According to the scheme, the pneumatic double-jaw chuck has the advantages that clamping effects can be conveniently and quickly realized, the pneumatic double-jaw chuck is easy to operate, castings of the mini-tillers can be quickly fixed, and accordingly the production efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a pneumatic double-jaw chuck for a tiller. Background technique [0002] Tillers are powered by small diesel engines or gasoline engines, and have the characteristics of light weight, small size, and simple structure. Tillers are widely used in dry land, paddy fields, orchards, etc. in plains, mountains, and hills. Equipped with corresponding equipment, it can be used for pumping, power generation, spraying, spraying and other operations, and can also be towed for short-distance transportation. The tiller can be used freely in the field, which is convenient for users to use and store, eliminating the need for large-scale agricultural machinery to enter The troubles of mountainous fields are the best choice for farmers and consumers to replace cattle plowing. [0003] There are many castings in the micro tillage machine that need to be end-face processed, but the clamping tools in the prior art are often not fixed firmly or th...
