Abstract
The invention relates to a spring sheet clamp which comprises a transition flange which is connected with a clamp body through a screw. Radial grooves are formed in spring sheets, and the spring sheets are sleeved on a boss of the body. When the screw is tightly screwed, a pressing plate presses on the spring sheets, an outer circle is expanded when the spring sheets are pressed, and a workpiece can be firmly pressed. For ensuring positioning reliability, a rigid positioning boss is arranged on the body, the workpiece is installed on the clamp with the end face and an inner hole as positioning references, the workpiece can be reliably clamped by slightly screwing the screw, and processing of the outer circle and the other end face can be facilitated. The spring sheet clamp is made of carburizing steel, the spring sheets are made of No.45 steel, inner circles and the outer circles of the spring sheets must be guide circles, the outer circles of the spring sheets need to be installed on the body and be slightly and firmly pressed.
Description
Technical field
The present invention relates to a kind of spring leaf anchor clamps.
Background technology
Existing anchor clamps because structural defective causes clamping force inhomogeneous, in use cause workpiece deformation easily.Secondly, the inside and outside circle concentricity is larger, causes the workpiece disqualification rate higher.
Summary of the invention
The present invention is in order to solve the above-mentioned technical problem of existing spring leaf anchor clamps, and the technical scheme of taking is: a kind of spring leaf anchor clamps, comprise excessive ring flange, and link together by screw and chuck body.Have radial slot on the spring leaf.These spring leafs are enclosed within on the boss of body.
When tightening screw, pressing plate is just pressed to spring leaf, and behind the spring leaf pressurized, cylindrical has just swollen, just can be Work-sheet pressing.
For the reliability that guarantees to locate, at body a rigidity spigot edge is arranged, workpiece is installed on the anchor clamps as positioning datum with end face and endoporus, as long as tighten gently screw, just can be reliably with Workpiece clamping, in order to carry out the processing of cylindrical and other end.
The diameter of spring leaf is at 100-300cm, and thickness is at 5 ~ 10cm, and result of use is best.The clamping force of anchor clamps is even, is difficult for making workpiece deformation, can be used for processing the thin-wall sleeve shape workpiece of 2 class precisions, and the concentricity of its inside and outside circle can reach 0.01cm.Can produce axial force when spring leaf compresses, make workpiece end face and anchor clamps locating surface close and, so just guaranteed workpiece stablizing and precision in process.
This clamp structure is simple, and is easy to manufacture, and cost is lower.Easy to operate, efficient is high.Be fit to produce by batch.
Description of drawings
Fig. 1 is partial structurtes profile of the present invention.
The specific embodiment
A kind of spring leaf anchor clamps comprise excessive ring flange 1, link together by screw 2 and chuck body 3.Have radial slot on the spring leaf.These spring leafs are enclosed within on the boss of body.
When tightening screw, pressing plate 5 is just pressed to spring leaf 4, and behind the spring leaf pressurized, cylindrical has just swollen, just can be Work-sheet pressing.
For the reliability that guarantees to locate, at body a rigidity spigot edge is arranged, workpiece is installed on the anchor clamps as positioning datum with end face and endoporus, as long as tighten gently screw, just can be reliably with Workpiece clamping, in order to carry out the processing of cylindrical and other end.
Body adopts carburizing steel to make.Spring leaf adopts No. 45 steel to make, and the inside and outside circle of spring leaf must be led circle.The cylindrical of spring leaf should be contained on the body, and fastens gently.
Claims (1)
1. spring leaf anchor clamps, comprise excessive ring flange, link together by screw and chuck body, it is characterized in that: have radial slot on the spring leaf, these spring leafs are enclosed within on the boss of body, at body a rigidity spigot edge are arranged, workpiece is installed on the anchor clamps as positioning datum with end face and endoporus, as long as tighten gently screw, just can be reliably with Workpiece clamping, in order to carry out the processing of cylindrical and other end.
