Abstract
The invention relates to a method for automatically displaying the size range of claw on the holdfast chuck of machine tool. The main accessory holdfast chuck of common machine tool can not display the present size range of claw. The plane of front end of inventive holdfast chuck has scale to record number; and the vertical surface of claw has a arrowhead mark; therefore its size can be recorded and displayed on the holdfast chuck at any time without reference to the size ranges of positive claw and passive claw. The invention has simple theory and easy production which can make the operation of machine tool easier.
Description
Affiliated technical field:
The present invention relates to the dog chuck of lathe main accessories, especially on dog chuck, can show a kind of method of claw magnitude range automatically.
Background technology:
At present, known lathe main accessories dog chuck can not show claw state size dimension scope at that time.The operator does not know the size dimension scope that claw was actual at that time yet, as when knowing the diameter of required holding workpiece, length and width size dimension, so just is easy to generate on chuck if need piece-holder; Operator or the clamping range of earlier estimating to transfer big claw are put into to regulate behind the workpiece again and are clamped, or directly relatively whether the magnitude range of claw is suitable with workpiece, regulate its magnitude range again and clamp.Like this, operation was both inconvenient, wasted man-hour again.
Summary of the invention:
In order to make dog chuck and cooperating of claw can show its size dimension scope of state at that time automatically, the invention provides a kind of claw method of state size dimension scope at that time that on dog chuck, can show automatically.This method is applicable to that fully the positive and negative claw of three-jaw self-centering chuck or four-jaw chuck uses.It can not only automatically demonstrate on the chuck each claw size dimension scope of state at that time, and method is simple, and is easy to manufacture, both easy during operation, saves man-hour again.
The technical solution adopted for the present invention to solve the technical problems is: at the front end of three-jaw self-centering chuck or four-jaw chuck, on every plane perpendicular to the forward and backward both sides of claw on the plane; The plane of clockwise direction claw front is the front, and having with the chuck hub is diameter, the specification size of starting point by chuck, with little calibration record number to big tactic its positive pawl minimum grip number and maximum grip stretching number; Clockwise direction claw plane behind is the back, and having equally with the chuck hub is starting point, presses diameter of chuck, specification size, and order is arranged the calibration record number of its anti-pawl minimum grip number and maximum grip number from small to large.Be carved with an arrow at the vertical plane of positive pawl claw front and the vertical plane of anti-pawl claw back near the appropriate position of chuck hub, the minimum of a value calibration record number when this symbol should the claw on chuck be tightened to the minimum dimension scope on the chuck plane, positive alignment claw front and back.Because the arrow on the claw is that the minimum dimension scope number with the calibration record number of forward and backward of claw is a starting point, so arrow records and demonstrate claw size dimension scope at that time at any time with regard to the calibration record number of aiming at back, claw front all the time when jaw adjustment moves or during inactive state.No matter be three-jaw self-centering chuck, or four-jaw chuck, the calibration record number on its every clockwise forward plane of claw is applicable to that the record of positive pawl claw is supporting; And the calibration record number on every claw clockwise direction backward plane is applicable to that the record of anti-pawl claw is supporting.
The invention has the beneficial effects as follows: this method principle is simple, easy to manufacture, easy and simple to handle, can play the raising working efficiency, the effect of saving man-hour.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 be method of the present invention on three-jaw self-centering chuck with the design sketch that is used of positive pawl claw.
Fig. 2 be method of the present invention on four-jaw chuck with the design sketch that is used of anti-pawl claw.
Among the figure 1, chuck, 2, positive pawl claw, 3, anti-pawl claw, A calibration record number, B arrow.
The specific embodiment:
In Fig. 1, be example for the 160mm three-jaw self-centering chuck with the diameter, having with the chuck hub point on the plane of clockwise every the claw front of its front end is starting point, by the minimum grip number of its positive pawl claw, maximum stretching is counted 3mm-160mm tactic calibration record number from small to large; And have with the chuck hub point on the plane of every claw clockwise direction back is the minimum grip number of starting point by its anti-pawl claw, and maximum grip is counted the tactic from small to large calibration record number of 55mm-145mm.The arrow of its positive pawl claw front is to be tightened to minimum grip start position as it when counting 3mm at claw, and just in time aims at the 160mm point of calibration record number when its arrow moves to edge backward.Because the calibration record number on the above-mentioned chuck plane and the relation of the arrow on two faces of its claw, no matter be its positive pawl, anti-pawl in moving or during inactive state, the arrow on the claw has just write down and has demonstrated the claw size dimension scope of state at that time all the time.
In the embodiment shown in Figure 2, be that the four-jaw chuck of 160mm is an example equally with the diameter, the minimum grip number of its positive pawl claw, maximum grip is counted the calibration record number of 8mm-80mm, every clockwise front of claw; The minimum grip number of its anti-pawl claw, maximum grip are counted the calibration record number of 50mm-160mm, same back at every claw.Arrow on the claw is to be the center with the chuck too; With the minimum grip number of positive and negative claw be starting point.The rule that present embodiment embodied is: just can know on the chuck the positive pawl size dimension scope of state at that time when the calibration record of reading positive pawl claw front is counted.The calibration record number of reading anti-pawl claw back just can be known on the chuck the anti-pawl size dimension scope of state at that time.
Claims (2)
- The method that 1, can show the claw magnitude range on a kind of machine chuck automatically, the calibration record number is arranged on the plane of chuck front end, with the arrow on the claw vertical plane, it is characterized in that: the calibration record number of every claw clockwise direction front, to write down what show be positive pawl claw size dimension scope at that time on the chuck: the calibration record number of every claw clockwise direction back, what institute write down demonstration is anti-pawl claw size dimension scope at that time on the chuck; Its calibration record number is to be starting point with the chuck hub, presses the minimum grip number and the maximum grip number order from small to large of the size dimension scope that claw clamps and arranges.
- 2, according to the method that can show the claw magnitude range on claims 1 described a kind of machine chuck automatically, it is characterized in that: the arrow on every claw is to be starting point with the chuck hub, from inside to outside moves forward and backward; The calibration record number of the arrow of front indication record is a positive pawl claw magnitude range at that time on the claw vertical plane, and the calibration record number of the arrow indication record of its back is an anti-pawl claw size dimension scope at that time.
