Abstract
The invention relates to an automatic positioning device for a machine tool, belonging to the field of machine tools. The automatic positioning device is provided with a pin roll and is characterized in that a spring is sleeved on the pin roll, the upper end of the pin roll is fixed with a sleeve, the pin roll at the lower end of the spring is provided with a gasket, the spring is compressed between the gasket and the sleeve, a gland is sleeved on the sleeve, one end of a guide key is fixed at the lower side of the pin roll, a positioning pin vertical to the pin roll is arranged below the pin roll, a guide groove forming a certain oblique angle with the axial direction of the positioning pin is processed on the positioning pin, and the other end of the guide key is positioned in the guide groove of the positioning pin. The invention has the advantages of simple structure, safety, reliability, no need of manual operation and accuracy of positioning.
Description
Technical field
The present invention relates to machine tool field, especially a kind of gantry, the lathe automatic positioning equipment when the boring ram that lands grasps the annex head automatically.
Background technology
As everyone knows: gantry mill and floor-type milling ﹠ boring machine when grasping the annex head, because manually-operated is wasted time and energy, now adopt automatically mostly and grasp, need not manually-operated, but when grasping automatically, on the keyway often very difficult and in the annex head of the straight end-face key on the main shaft is corresponding, adopt tool locating usually, can not break away from fully manually, waste time and energy.
Summary of the invention
Purpose of the present invention just is to provide a kind of lathe automatic positioning equipment in order to overcome the difficult correspondence problem of keyway in main shaft straight end-face key and the annex head, and is simple in structure, safe and reliable, need not manually-operated, accurate positioning.
The present invention adopts following technical solution: a kind of lathe automatic positioning equipment, be provided with bearing pin, it is characterized in that being set with on the bearing pin spring, the bearing pin upper end is fixed with cover, on the bearing pin of spring lower end pad is installed, spring is compressed between pad and the cover, put and be set with gland, feather key one end is fixed on the bearing pin downside, the bearing pin below is provided with the alignment pin vertical with bearing pin, be processed with the gathering sill that axially is the oblique angle with alignment pin on the alignment pin, the feather key other end is positioned at the gathering sill of alignment pin.
The invention has the beneficial effects as follows, simple in structure, safe and reliable, need not manually-operated, accurate positioning.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 structural representation of the present invention.
Fig. 2 is the state diagram after the gripper components of the present invention.
1. tie-plates among the figure, 2. gland, 3. cover, 4. spring, 5. pad, 6. bearing pin, 7. alignment pin, 8. feather key.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments, to help understanding content of the present invention.
As shown in Figure 1 and Figure 2, the present invention is provided with bearing pin 6, be set with spring 4 on the bearing pin 6, bearing pin 6 upper ends are fixed with cover 3, on the bearing pin 6 of spring 4 lower ends pad 5 are installed, spring 4 is compressed between pad 5 and the cover 3, cover is set with gland 2 on 3, and feather key 8 one ends are fixed on bearing pin 6 downsides, and bearing pin 6 belows are provided with the alignment pin 7 vertical with bearing pin 6, be processed with the axial gathering sill that becomes a fixed inclination with alignment pin 7 on the alignment pin 7, feather key 8 other ends are positioned at the gathering sill of alignment pin 7.
The present invention is before lathe grasps the annex head, annex head automatic positioning equipment state as shown in Figure 1, one end of alignment pin 7 is inserted in the locating hole of tie-plate 1, when lathe when grasping the annex head, the machine ram end face moves down, when grasping, ram end face elder generation contact sleeve 3, cover 3 is pressed into, and drives bearing pin 6 simultaneously and moves down, bearing pin 6 drives alignment pin 7 by feather key 8 and leaves tie-plate 1, tie-plate 1 is broken away from the location, state as shown in Figure 2, in the process that unloads the annex head, the ram end face moves up and unloads the annex head, overlap 3 simultaneously and be ejected under the effect of spring 4, cover 3 drives bearing pin 6 and moves up, and bearing pin 6 drives alignment pin 7 by feather key 8 and enters in the locating hole of tie-plate 1, tie-plate 1 is set, and state is got back to shown in Figure 1.
