Description
Technical field
The utility model relates to chuck handle, is a kind of modified scroll chuck spanner.
Background technology
The scroll chuck spanner is that a kind of utilization is distributed on moving radially of three movable jaws on the chuck body; The machine tool accessories of workpiece clamping and location; Be made up of movable jaw, the claw driving mechanism of chuck body and chuck head as the one of which, the operating side of chuck body is provided with spanner.When this type of scroll chuck spanner in use, usually owing to after operation is accomplished, forget taking-up, and injure the operator with flying out after the lathe rotation.For this reason; Patent No. ZL200620101634.7 like Chinese patent document publication; On March 28 2007 Granted publication day, the utility model name is called " a kind of scroll chuck spanner ", and this chuck handle comprises a wrench body and a spanner handle; It is characterized in that also comprising a spring, this spring housing is contained on the wrench body; The user is after using the scroll chuck spanner, and under the effect of spring force, wrench body can automatically eject the square hole from the scroll chuck excircle.But above-mentioned spring is arranged at the chuck head end of chuck body, influences the normal use of chuck head easily, and when spring comes off, the situation of unfavorable lathe work takes place easily.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of the utility model is to this area a kind of modified scroll chuck spanner to be provided, and it is not good enough to make it solve on existing market the like product structural design, awkward technical problem.Its objective is and realize through following technical scheme.
A kind of modified scroll chuck spanner, this chuck handle comprises chuck body, spanner, chuck head, and the external diameter and the spanner of chuck body one end are connected as a single entity, and the end face of the other end is provided with chuck head, and chuck head is provided with bevel gear, claw and flat thread; Said claw or be top, after the chuck body of this chuck handle inserted the startup hole of lathe, the activation member engagement of chuck head and lathe started lathe through rotating spanner, extracts this chuck handle after the lathe startup.Its structural design main points are to be provided with central through hole in the said chuck body, and push rod is set in the central through hole, and an end of push rod is positioned at the draught animals of chuck head, and the other end stretches out the central through hole of chuck and is provided with button.Push button after lathe starts, push rod stretches out chuck body, and chuck body and the startup hole of chuck head from lathe are ejected, and prevents that lathe from driving to fly out after this chuck handle rotates to injure the operator.
Push rod between said button and the chuck body is with spring, and spring is connected with button, chuck body respectively.Spring is used for push rod and resets, and when unclamping spanner, chuck body and chuck head eject the startup hole of lathe automatically, thereby further is convenient to the use of this chuck handle.
The utility model reasonable in design, easy to use, stability, security is good; The chuck handle that is suitable as lathe uses, ex hoc genus anne the architecture advances of product.
Description of drawings
Fig. 1 is the structural representation of the utility model, and dotted line is a push rod in the chuck body among the figure.
Fig. 2 is the user mode structural representation of the utility model.
Figure number and title: 1, chuck body, 2, spanner, 3, chuck head, 4, push rod, 5, spring, 6, button.
The specific embodiment
Combine accompanying drawing at present, the utility model structure is further described with making to be used as.Like Fig. 1, shown in Figure 2, the chuck body 1 one end external diameters and the spanner 2 of this chuck handle are connected as a single entity, and the end face of the other end is provided with chuck head 3, and chuck head is provided with bevel gear, claw and flat thread, and the structure of chuck head is identical with existing like product; Be provided with central through hole in the chuck body; Push rod 4 is set in the central through hole, and an end of push rod is positioned at the draught animals of chuck head, and the other end stretches out the central through hole of chuck and is provided with button 6; Push rod between button and the chuck body is with spring 5, and spring is connected with button, chuck body respectively.
When this chuck handle uses, offset, in the push rod income chuck body by chuck head and lathe starting drive; After this chuck handle operation lathe starts completion, unclamp spanner, this chuck handle is through spring action, and push rod ejects chuck head in the startup hole of lathe.Thereby when preventing to start lathe, the engagement of the activation member of chuck head and lathe causes this chuck handle to fly out and injures the operator.
