Abstract
The utility model relates to a chuck safe wrench, in particular to a chuck safe wrench suitable for a lathe. The chuck safe wrench comprises a wrench rod, a wrench body and a spring, wherein the wrench body is a ladder-shaped shaft, the wrench body is sleeved in a sleeve pipe, a step which is arranged in an inner hole of the sleeve pipe correspondingly is matched with the wrench body, and head portions of four directions of the wrench body penetrate through from one end of the sleeve pipe. The wrench rod is arranged in a radial through hole, far away from one end of the four-direction head portions, of the wrench body, the spring is arranged between the wrench body and the step of the sleeve pipe, a guide pin is arranged in the radial through hole, and the radial through hole is formed in the adaptive position where the wrench body is arranged in the sleeve pipe. A guide groove is formed in the sleeve pipe correspondingly. The chuck safe wrench avoids the phenomenon that the chuck wrench is put on an operation platform due to forgetting so as to cause safe accidents and achieves the aim of being safe, high-efficiency and practical. The chuck safe wrench is simple and reasonable in structure, easy to machine and produce, low in cost, and long in service life, and brings great convenience for a user.
Description
Technical field
The utility model relates to a kind of chuck handle, relates in particular to a kind of chuck safe wrench that is applicable to lathe.
Background technology
At present, each enterprise, factories and miness, school are when using engine lathe processing operation, and mechanical accident is very frequent, so intensified safety education in lathe processing operation Strengthens Safety Management, advanced technology being provided, improving mechanization degree, is a long-range mission of prevention and forecast.
Because the automaticity in when operation is not high, still by hand operation namely with the hands operates various handles continually, time length, energy high concentration, easy fatigue, have accumulate over a long period, the process that skill comes from practice.
In this case, if do not have safe precaution measure and safety device, the person, equipment breakdown just occur very easily.Engine lathe is to finish the work by higher rotating speed, and the cause that damages does not have disengaging to cause by chuck handle mostly.Particularly just study uses the workman of lathe and the student of skills practice training especially to show outstanding.Because the equipment operating performance is unfamiliar with or negligence and the error starting lathe is easy to occur the accident that chuck handle is hurted sb.'s feelings or damaged machine tool.Therefore, the design of chuck safe wrench is necessary on engine lathe.
Summary of the invention
The utility model proposes for the problems referred to above, purpose just provides and a kind ofly is suitable for that engine lathe directly uses, simple in structure, efficient, practical, processing and manufacturing is easy, and reaches and avoid causing the chuck safe wrench that security incident occurs by chuck handle being forgotten at operating desk.
The purpose of this utility model realizes by the following technical solutions:
The chuck safe wrench, it comprises: tommy bar, wrench body and spring, its wrench body is the ladder oblique crank Z, this wrench body is set in the sleeve pipe, and described casing tube internal hole is corresponding to be provided with step and wrench body matches, the cubic head of wrench body passes from an end of sleeve pipe, and wrench body is away from being provided with tommy bar in the cubic head one end radial direction through hole; Be provided with spring between the step of wrench body and sleeve pipe; The adapting position radial direction through hole that wrench body is positioned at sleeve pipe is provided with guide finger; And be provided with gathering sill at sleeve pipe accordingly.
Described spring is Compress Spring.
The utility model compared with prior art has following advantageous effect: the utility model is owing to adopted the corresponding step that is provided with casing tube internal hole of wrench body of ladder profile shaft to match, and between the step of wrench body and sleeve pipe, be provided with spring, reached and avoided causing that by chuck handle being forgotten at operating desk security incident occurs, thereby reached safer, efficient, practical.The utility model is simple and reasonable for structure, is easy to processing and manufacturing, and with low cost, and long service life brings great convenience to the user.
Description of drawings
Fig. 1 is sectional structure schematic diagram of the present utility model;
Fig. 2 is the sectional structure schematic diagram of the utility model duty;
Fig. 3 is the sectional structure schematic diagram of the utility model off working state.
Among the figure: tommy bar 1, wrench body 2, sleeve pipe 3, spring 4, guide finger 5, gathering sill 6.
The specific embodiment
Below in conjunction with specific embodiment the utility model is further described in detail; but protection domain of the present utility model is not limited by specific embodiment; be as the criterion with claims; in addition; with under the prerequisite of technical solutions of the utility model, any change or change that those of ordinary skills that the utility model is made realize easily can both fall within the claim scope of the present utility model.
Such as Fig. 1, Fig. 2, the utility model chuck safe wrench shown in Figure 3, it comprises tommy bar 1, wrench body 2 and Compress Spring 4, wrench body 2 is the ladder oblique crank Z, this wrench body 2 is set in the sleeve pipe 3, and described sleeve pipe 3 endoporus are corresponding to be provided with step and wrench body 2 matches, and the cubic head of wrench body 2 leans out from an end of sleeve pipe 3, and wrench body 2 is away from cubic head one end, and lean out the adapting position of sleeve pipe 3, be provided with tommy bar 1 in the radial direction through hole; Be provided with Compress Spring 4 between the step of wrench body 2 and sleeve pipe 3; Wrench body 2 is positioned at the adapting position of sleeve pipe 3, is provided with guide finger 5 in the radial direction through hole; And be provided with gathering sill 6 at sleeve pipe 3 accordingly.
During concrete the use: only need wrench body 2 is pressed downwards, guide finger 5 down slidings of wrench body 2 interior placements, spring 4 compresses, and complete when work, spring 4 automatically springs open, wrench body 2 is under the drive of spring 4, gathering sill 6 on sleeve pipe 3 moves upward, and makes the cubic head of wrench body 2 break away from the lathe operation platform, effectively prevents, has stopped because of human negligence and carelessness, forget from chuck and take off danger and the accident that spanner causes, make this type of security incident of engine lathe reduce to zero.
