Abstract
The invention belongs to the technical field of valve manufacturing, and particularly relates to a pneumatic clamp for broaching of a butterfly valve. The pneumatic clamp is characterized in that the pneumatic clamp comprises a cylinder, a fixing plate, a first clamping plate and a second clamping plate, connecting rods are fixed between the fixing plate and the first clamping plate, sliding rods are fixed on the second clamping plate, the sliding rods penetrate through the first clamping plate and are in sliding fit with the first clamping plate, and the sliding rods are connected with a piston rod of the cylinder through a connecting plate. The pneumatic clamp is simple in structure, is placed on a lathe to replace a chuck, quickly clamps workpieces through the cylinder, and greatly improves work efficiency.
Description
Technical field
The invention belongs to the manufacturing technology field of valve, particularly relate to a kind of butterfly valve reaming air-actuated jaw.
Background technology
Gate valve is also slide valve, is a kind of widely used valve.Its closed principle is that ram seal face is bright and clean with sealing surface of seat height, smooth consistent, bonded to each other, medium can be stoped to flow through, and rely on the model of backform, spring or flashboard, strengthen sealing effectiveness.It is a main cutting action in pipeline.Its advantage is: fluid resistance is little, and keying saves labour, and can use, do not have directionality when medium two-way flow, sealing surface not easily erosion during standard-sized sheet, and structure length is short, is not only applicable to doing minor valve, and is applicable to doing large valve.
In prior art, being all utilize lathe to process when processing the endoporus of butterfly valve, processing after being clamped by the valve body chuck of butterfly valve again, owing to all needing manually to loosen and tighten chuck at every turn, speed is comparatively slow, and operating efficiency is low.
Summary of the invention
The object of the invention is to the deficiency overcoming above-mentioned technology, and a kind of butterfly valve reaming air-actuated jaw is provided, improve working (machining) efficiency.
The present invention for achieving the above object, by the following technical solutions: a kind of butterfly valve reaming air-actuated jaw, it is characterized in that: comprise cylinder, fixed head, the first clamping plate and the second clamping plate, connecting rod is fixed with between described fixed head and the first clamping plate, described second clamping plate are fixed with sliding bar, described sliding bar passes described first clamping plate and is slidably matched in it, and described sliding bar is connected by the piston rod of connecting plate with described cylinder.
Described first clamping plate are provided with cushion block.
The invention has the beneficial effects as follows: structure of the present invention is simple, this fixture to be placed on lathe in order to replace chuck, to be clamped fast by cylinder, substantially increase operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, fixed head; 2, the first clamping plate; 3, the second clamping plate; 4, connecting rod; 5, sliding bar; 6, connecting plate; 7, piston rod.
Detailed description of the invention
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of butterfly valve reaming air-actuated jaw, comprises cylinder, fixed head 1, first clamping plate 2 and the second clamping plate 3, connecting rod 4 is fixed with between described fixed head and the first clamping plate, connecting rod, by fixed head and the first Boards wall, leaves certain distance between the two, facilitates piston rod to move.Described second clamping plate are fixed with sliding bar 5, described sliding bar passes described first clamping plate and is slidably matched in it, described sliding bar is connected with the piston rod 7 of described cylinder by connecting plate 6, when the piston rod of cylinder moves, drive sliding bar to slide in the first clamping plate, drive the second clamping plate to move left and right simultaneously.In use, be placed on by the valve body of butterfly valve between the first clamping plate and the second clamping plate, the piston rod of cylinder drives the second clamping plate to move to the direction of the first clamping plate, just can carry out processing its reaming after the valve body of the first clamping plate and the second clamping plate clamping butterfly valve.This device can be arranged on lathe of the prior art.In order to make fixing the following firmly of the valve body of butterfly valve, described first clamping plate are provided with cushion block.
Structure of the present invention is simple, to be placed on by this fixture on lathe in order to replace chuck, to be clamped fast, substantially increase operating efficiency by cylinder.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
