Abstract
The invention relates to a graduated disk with a fluorescent screen protective device. In the graduated disk, a disk surface is divided into a plurality of fan-shaped parts equally, and a fixture for clamping a workpiece is arranged on each part. The graduated disk is characterized by also comprising a driving device for driving a disk body to rotate, a safety fluorescent screen device and a circuit control system; the driving device and the safety fluorescent screen device are connected with the circuit control system respectively; the safety fluorescent screen device comprises a signal emitting device and a signal receiving device; an output circuit of the signal emitting device is connected with the circuit control system; after the safety fluorescent screen device is opened, a fluorescent screen formed between the signal emitting device and the signal receiving device is positioned on the outer side of the disk body of the graduated disk, namely a connecting line between the signal emitting device and the signal receiving device is non-intersected with the disk surface of the graduated disk; and the driving device is provided with a driving button, and the driving button and the disk body of the graduated disk are positioned on both sides of the fluorescent screen respectively. The graduated disk has the advantage of simple structure, is easy to implement and improves the safety of production greatly.
Description
Technical field
The invention belongs to field of machining, be specifically related to a kind of index dial with light curtain protective device.
Background technology
Index dial be with piece-holder on chuck or two top, and make the machine tool accessories of its rotation, calibration and location.The workman can adopt the rotation of mechanical actuation device control disk body usually when using index dial, have certain danger like this, if workman's health has been run into drive unit because of carelessness, disk body is rotated, and might cause certain injury to workman's health.In order to guarantee safety in production, be necessary on index dial, to add safety device.Mostly adopt the safety device of contact in the prior art, switch repeatedly can reduce work efficiency of workers, and is easy to generate operate miss.
Summary of the invention
Technical purpose of the present invention is to solve the drawback that exists in the prior art, and a kind of index dial with light curtain protective device is provided.
Technical scheme of the present invention is a kind of index dial with light curtain protective device, and described index dial card is divided into the part of plurality of sector, is respectively arranged with the frock of holding workpiece on each part, it is characterized in that:
Described index dial also comprises drive unit, safe light curtain device and the circuit control system that drives the disk body rotation, and described drive unit, safe light curtain device are connected with circuit control system respectively;
Described safe light curtain device comprises signaling device, signal receiving device, after the safe light curtain device is opened, the light curtain that forms between signaling device and the signal receiving device is in the outside of index dial disk body, and promptly line between signaling device and the signal receiving device and index dial card are non-intersect;
Described drive unit is provided with activation button, and activation button is by the light curtain, with the index dial disk body respectively in the both sides of light curtain.
Described safe light curtain device is provided with two columns, and signaling device, signal receiving device are installed respectively, is respectively equipped with signal sending unit device or signal receiving unit device that several rules is arranged on each column.
Between the signal sending unit device or the distance between the signal receiving unit device be less than or equal to 4cm.
Described column is provided with base, and described base is fixed on ground or the workbench by fixture.
After opening the safe light curtain device, workman's both hands reach on the index dial by the light curtain, carry out work, part light is blocked, at this moment circuit control system will receive a signal, and the drive unit of control index dial is forced to quit work, even workman's health touches activation button because of carelessness, index dial can not rotate yet, and the workman is after finishing the work, and hand withdraws from from the light curtain, the drive unit of circuit control system control index dial is in holding state, the workman rotates index dial again by the operation activation button, has improved the security that the workman produces greatly.And the present invention is simple in structure, easy to implement.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of index dial.
The specific embodiment
In order to illustrate technical scheme of the present invention and technical purpose, the present invention is done further introduction below in conjunction with the drawings and the specific embodiments.
As shown in the figure; a kind of index dial with light curtain protective device; described index dial card 1 is divided into the part of plurality of sector; be respectively arranged with the frock of holding workpiece on each part; described index dial also comprises drive unit 2, safe light curtain device 3 and the circuit control system that drives the disk body rotation, and drive unit 2, safe light curtain device 3 are connected with circuit control system respectively.
Safe light curtain device 3 comprises signaling device, signal receiving device, after safe light curtain device 3 is opened, the light curtain that forms between signaling device and the signal receiving device is in the outside of index dial disk body, and promptly line between signaling device and the signal receiving device and index dial card are non-intersect.The distance of light curtain and index dial can specifically be provided with according to production or workman's operating habit.
Described drive unit 2 is provided with activation button, and activation button is arranged on a side of workman's health, with the index dial disk body respectively on the limit of light curtain.
Further, safe light curtain device 3 can be provided with two columns, signaling device, signal receiving device are installed respectively, be respectively equipped with signal sending unit device or signal receiving unit device that several rules is arranged on each column, every group of signal send and receiving unit device between form beam signal.
Between the signal sending unit device or the distance between the signal receiving unit device be less than or equal to 4cm, the density of light beam has determined great body part just can be induced by the light curtain, so the distance between the light beam should the maximum width that can not surpass human wrist.
Described column is provided with base, and described base is by can fixture being fixed on ground or the workbench, to strengthen the stability of light curtain.
Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within protection scope of the present invention.
