Abstract
The utility model discloses a safety chuck wrench of a multifunctional lathe, which relates to the technical field of lathe tools. The safety chuck wrench comprises a chuck wrench body, a handle and a square head, wherein the handle is arranged at the upper end of the chuck wrench body; the square head is fixed at the lower end of the chuck wrench body; an inner sleeve is sheathed on the bottom of the chuck wrench body; a spring is connected at the upper end of the inner sleeve; the other end of the spring is fixed at the upper end of the chuck wrench body; outer sleeves are sheathed outside the inner sleeve and the spring; the inner sleeve can slide up and down in the outer sleeve; and a detachable replaceable connector is arranged on the square head. The safety chuck wrench has the advantages of not only being capable of achieving the functions of a chuck wrench and a tool post wrench, but also having the function of a hexagonal socket wrench; and with the safety chuck wrench, the labor intensity is reduced, the labor efficiency is improved, the manufacturing cost is reduced, and the safety performance is good.
Description
Technical field
The utility model relates to the lathe tools technical field, specifically is a kind of multi-purpose machine safety chuck spanner.
Background technology
For a long time, in the operation of lathe the most frequently used to spanner two pairs are arranged, a pair is a chuck handle, another pair is a knife rest square head screw spanner.So just have the following disadvantages: on the one hand, two spanners use in the operation to be changed frequently, in use often has the situation generation that the operator takes spanner by mistake, two secondary spanners respectively have used, can not replace,, influence operating efficiency so need return replacing; Two secondary spanners take more space in the process of taking care of and depositing simultaneously.On the other hand, the beginner forgets sometimes after using the chuck handle clamping work pieces it taken off, and chuck handle just might take place thrown away by chuck and hurts sb.'s feelings thereby start lathe at this moment, has serious potential safety hazard.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of multi-purpose machine safety chuck spanner, has two kinds of functions of chuck handle and tool-post wrench, stops potential safety hazard.
The utility model is realized with following technical scheme: a kind of multi-purpose machine safety chuck spanner comprises the chuck handle main body, is installed in the handle of chuck handle main body upper end and is fixed on the square head of chuck handle main body lower end; Bottom in the chuck handle main body is set with inner sleeve, and the upper end of inner sleeve is connected with spring, and the other end of spring is fixed on the upper end of chuck handle main body; Outer cover at inner sleeve and spring is equipped with outer sleeve; Inner sleeve can slide up and down in outer sleeve; Dismountable interchangeable joint is installed on the square head.
The beneficial effects of the utility model are: not only can realize two kinds of functions of chuck handle and tool-post wrench, also have the effect of hexagonal socket wrench; Reduce labor intensity, improved efficiency; Reduce manufacturing cost, the security performance height.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation;
Fig. 2 is a clamp wrench body schematic diagram;
Fig. 3 is the A-A view of Fig. 2;
Fig. 4 is the inner sleeve schematic diagram.
Among the figure: 1, square head, 2, the chuck handle main body, 3, inner sleeve, 4, outer sleeve, 31, through-hole groove, 5, handle, 6, spring, 7, pin, 8, interchangeable joint.
The specific embodiment
Shown in Fig. 1～4, multi-purpose machine safety chuck spanner has a chuck handle main body 2 and is installed in the handle 5 and the square head 1 that is fixed on chuck handle main body 2 lower ends of chuck handle main body 2 upper ends.Have the cross through hole at the top of chuck handle main body 2, handle 5 is installed in the upper end of chuck handle main body 2 by the cross through hole.Handle 5 is divided into two sections, and every section tail end plays anti-skidding effect through the annular knurl processing.Two sections handles can use separately, also can use together in case of necessity.According to producing needs, clamp wrench body 2 and square head 1 both can be processed separately, also can process for one.In the present embodiment, clamp wrench body 2 and square head 1 are one, adopt die forging processing, one-shot forming; And then brill cross through hole; Square head 1 local heat treatmet.Be set with inner sleeve 3 in the bottom of chuck handle main body 2, the upper end of inner sleeve 3 is connected with spring 6, and the other end of spring 6 is fixed on the upper end of chuck handle main body 2.By the mutual stressed effect of spring 6 with inner sleeve 3, the back instrument ejects from chuck automatically finishing using.Outer cover at inner sleeve 3 and spring 6 is equipped with outer sleeve 4, opens a through-hole groove 31 on inner sleeve 3, and pin 7 passes through-hole groove 31 outer sleeve 4 is fixed on chuck handle main body 2, and inner sleeve 3 can slide up and down in the scope of through-hole groove.Outer sleeve 4 plays the effect of whole chuck handle main body 2 of protection and spring 6.In order to realize that chuck handle has chuck handle and two kinds of functions of tool-post wrench, then need tool-post wrench is placed on the main body of chuck handle, tool-post wrench also has only the internal square hole of head to play practical function in use, so dismountable interchangeable joint 8 is installed on square head 1.Described interchangeable joint 8 is interior square joint, the internal square hole of an end of interior square joint for matching with square head 1, and another termination is an internal square hole, uses as tool-post wrench.Described interchangeable joint 8 is a hexagonal shoulder nipple, the internal square hole of an end of hexagonal shoulder nipple for matching with square head 1, and another termination is an inner hexagonal hole, uses as hexagonal socket wrench.
The course of work: under situation about not stressing, inner sleeve 3 stretches out, when using, after the operator gives its external force effect, inner sleeve 3 is stressed, withstands spring 6 simultaneously, makes spring 6 be compressed, what this moment, square head 1 was relative just is in inner sleeve 3 outsides, so just can realize the function of chuck handle.When operator's external force was cancelled, inner sleeve 3 applied reaction force to the chuck of lathe under the effect of spring force, and chuck handle just can be ejected from the square hole screw of chuck by the elastic force of himself like this.Interior square joint is installed on the square head 1, has realized the function of tool-post wrench; Hexagonal shoulder nipple is installed on the square head 1, has realized the function of hexagonal socket wrench.
