Abstract
The utility model discloses a lathe chuck lock comprising a chuck shell, wherein the shell is provided with a chuck spanner mounting hole, the lathe chuck lock further comprises a sensitive switch and a loss prevention block, the sensitive switch is arranged in a cavity of the shell, one end of the loss prevention block is in contact with the spanner mounting hole and is capable of freely sliding, the other end of the loss prevention block is in contact with a tilting lever of the sensitive switch, a limiting device is arranged in the spanner mounting hole or the limiting device is arranged on the loss prevention block, and the wiring end of the sensitive switch is connected with a lathe control loop; the wiring end of the sensitive switch comprises a public input end, a normally closed output end and a normally open output end; the lathe control loop is a spindle motor contact coil loop; the limiting device arranged in the spanner mounting hole is a retainer ring, the limiting device arranged on the loss prevention block is a lug boss on the contact end of the tilting lever of the sensitive switch; and the lathe chuck lock disclosed by the utility model prevents the chuck spanner from flying out from the chuck at a high speed so as to avoid safety misadventure.
Description
Technical field
The utility model relates to the machining equipment field, relates in particular to a kind of lathe chuck lock.
Background technology
The footpath that the lathe chuck of prior art is locked in chuck upwards is provided with the spanner installing hole, thus the purpose that the claw that utilizes rotatablely moving of lathe chuck lock spanner to make chuck radially moves and reaches clamping and unclamp workpiece.The defective that this structure exists is: some personnel, particularly neophyty operation person did not just start power supply sometimes before lathe chuck lock spanner takes out after the lathe workpiece loading and unloading is accomplished; After the machine tool chief axis rotation; Chuck handle flies out at a high speed from chuck, is easy to security incident to occur, has serious potential safety hazard.
Summary of the invention
The purpose of the utility model is exactly before lathe chuck lock spanner takes out, just to start power supply in order to solve the operator, and chuck handle flies out from chuck, the problem of security incident occurs; A kind of lathe chuck lock is provided; Stopping chuck handle flies out at a high speed from the chuck and causes the generation of security incident.
To achieve these goals, the present invention adopts following technical scheme:
A kind of lathe chuck lock comprises the chuck shell, and shell is provided with the chuck handle installing hole; Also comprise microswitch, loss prevention piece, said microswitch are located in the cavity of shell; Said loss prevention piece one end contacts and is free to slide with the spanner installing hole; The said loss prevention piece other end contacts with the bar that sticks up of microswitch, is provided with stopping means in the said spanner installing hole or described loss prevention piece is provided with stopping means, and the terminals of said microswitch are connected with the lathe control loop.
The terminals of said microswitch comprise public input and normally closed output and Chang Kai output.
Described lathe control loop is spindle motor contactor coil loop.
The stopping means that is provided with in the said spanner installing hole is a back-up ring.
Stopping means on the described loss prevention piece for microswitch stick up the contact boss of an end of bar.
The beneficial effect of the utility model: because the lathe chuck lock; Be provided with microswitch, loss prevention piece, said microswitch are located in the cavity of shell; Said loss prevention piece one end contacts and is free to slide with the spanner installing hole; The said loss prevention piece other end contacts with the bar that sticks up of microswitch, is provided with stopping means in the said spanner installing hole or described loss prevention piece is provided with stopping means, and the terminals of said microswitch are connected with the lathe control loop.In case just do not start power supply before after the lathe workpiece loading and unloading is accomplished, lathe chuck being locked the spanner taking-up; This moment is because the gravity of chuck handle is delivered to the bar that sticks up of microswitch through the loss prevention piece, thereby thereby the normally closed switch that will be connected with the control loop of spindle motor contactor coil disconnection can not be connected the power supply major loop makes machine tool chief axis not rotate.Owing to be provided with spacing back-up ring in the spanner installing hole, perhaps on the loss prevention piece, establish boss with the bar end that contacts that sticks up of microswitch, guarantee that the loss prevention piece is reliable in the spanner installing hole to move and can not therefrom deviate from.The generation of having avoided chuck handle and loss prevention piece to fly out, stopped security incident in the spanner installing hole.
Description of drawings
Fig. 1 is the structural representation of the utility model lathe chuck lock.
Among the figure, 1-spanner, 2-shell, 3-loss prevention piece, 4-microswitch, 5-output switching terminal, 6-boss, 7-back-up ring.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
A kind of lathe chuck lock as shown in Figure 1; Comprise chuck lock shell 2, shell 2 is provided with chuck handle 1 installing hole, also comprises microswitch 4; Loss prevention piece 3; Said microswitch 4 is located in the cavity of shell 2, and said loss prevention piece 3 one ends contact and are free to slide with spanner 1 installing hole, and said loss prevention piece 3 other ends contact with the bar that sticks up of microswitch 4; Be provided with stopping means in said spanner 1 installing hole or described loss prevention piece 3 is provided with stopping means, the terminals of said microswitch 4 are connected with the lathe control loop; The terminals of said microswitch 4 comprise public input and normally closed output and Chang Kai output; Described lathe control loop is spindle motor contactor coil loop; For prevent that the loss prevention piece from deviating from chuck handle 1 installing hole, can take to comprise the following structure that prevents: the one, in said spanner 1 installing hole, be provided with back-up ring 7; The 2nd, establish boss 6 at the bar end that contacts that sticks up of described loss prevention piece 3 and microswitch 4, the external diameter of boss 6 is greater than the internal diameter of said loss prevention piece 3 with spanner installing hole contact position.
Though the above-mentioned accompanying drawing that combines is described the specific embodiment of the utility model; But be not restriction to the utility model protection domain; One of ordinary skill in the art should be understood that; On the basis of the technical scheme of the utility model, those skilled in the art need not pay various modifications that creative work can make or distortion still in the protection domain of the utility model.
