Abstract
The utility model discloses a self-positioning device for machining of a screw rod. The self-positioning device consists of a base and a machine head, wherein a left positioning piece and a right positioning piece for clamping the screw rod to machined are arranged on the base on the two sides of the machine head; and a power device is connected with the left positioning piece and the right positioning piece and is used for supplying power. The self-positioning device has the characteristics of simple structure, clamping easiness, high precision and low cost.
Description
Technical field
The utility model belongs to the Machining Technology field, especially relates to a kind ofly need to carrying out the self-align device of feeding processing to long lead screw.
Background technology
In mechanical processing process, particularly to long lead screw, during such as several meters even longer lead screw machining, because the Rigidity of stressed and workpiece self, be easy to cause the distortion of leading screw, thereby affect the machining accuracy of leading screw, according to traditional clamp method, processing parts is generally all shorter, method commonly used for be by fairlead position, guide, but add man-hour for the part of different-diameter, need the fairlead of replacing different size, these class methods are cumbersome, and stricter for the diameter control of part; By back-moving spring part is clamped, but this type of situation is not suitable for for high-precision requirement; Utilize pinch roller that part is carried out clamping by transfer case, but this type of situation, higher for the required precision of transfer case, adapter is more, and cost is higher.
Summary of the invention
The purpose of this utility model is to improve the deficiency of prior art and a kind of simple in structure, clamping is easy, precision is high, cost is low lead screw machining self locating device is provided.
The purpose of this utility model is to realize like this, a kind of lead screw machining self locating device, formed by pedestal and head, be characterized in that pedestal in the head both sides is provided with left keeper and the right keeper for the processed leading screw of clamping, power set connect left keeper and right keeper and power are provided.
In order further to realize the purpose of this utility model, can be that described left keeper and right keeper are that upper clamping limb and transmission arm are fixed together and form holder, the side of transmission arm and lower clamping limb is provided with tooth bar, the tooth bar engagement of travelling gear and transmission arm, lower clamping limb.
In order further to realize the purpose of this utility model, can be that upper clamping limb and the transmission arm upper holder that forms that is fixed together is slidingly mounted on the slide.
The utility model is distinguishing feature and good effect compared with the prior art: the utility model is that the pedestal in the head both sides is provided with left keeper and the right keeper for the processed leading screw of clamping, power set connect left keeper and right keeper and power are provided, guarantee the precision of positioning element clamping leading screw by corresponding power set control, only need before processing, once to adjust, just can carry out lots processed to leading screw, about twice location, reduced head part has been added man-hour, because of distortion stressed and that part self rigidity factor problem causes, thereby guarantee machining accuracy; Left keeper and right keeper are that upper clamping limb and transmission arm are fixed together and form holder, the side of transmission arm and lower clamping limb is provided with tooth bar, the tooth bar engagement of travelling gear and transmission arm, lower clamping limb, simple in structure, lower hold assembly and upper hold assembly can keep being synchronized with the movement in opposite directions, thereby leading screw is carried out clamping and positioning; The upper clamping limb and the transmission arm that are fixed together are slidingly mounted on the slide, go up like this clamping limb and transmission arm and move steadily, have improved operating accuracy; Thereby the utility model can carry out the control of linearity to workpiece by the center of adjusting left and right sides keeper and head working position, and is high to reach corresponding required precision precision.
