Abstract
An argon arc welding synchronous automatic control eye protector relates to a device for eye protection in argon arc welding, in particular to an eye protector capable of moving the screening glasses automatically and working with the argon arc welding synchronously. The convex part of a cam track is clamped into the grooves of concave wheels at four corners of the screening glasses connected with a rack which is meshed with a gear of a motor and provided with a magnet at the upper end. The motor is respectively connected with a magnetic-controlled switch 1TJ, 2TJ of the magnet and a relay 1SJ [2], the 1TJ and 2TJ are connected with a relay 1SJ [1], and the power is connected with an argon arc welding switch K, a relay 1SJ and a relay 2SJ. The utility model drives the rack to move upward by the gear on the motor. When the upper magnet reaches the magnetic-controlled switch 1TJ, the motor will stop working. Then the staff starts the argon arc welding switch aiming at the welding point to make the rack move downward. When the magnet reaches the magnetic-controlled switch 2TJ, the motor will stop working and the argon arc welding will start working. The utility model has simple structure, convenient operation, high working efficiency, good welding quality and effective protection of eyes from arc light injury.
Description
Technical field
This utility model relates to a kind ofly can protect the purpose utensil when being used for argon arc welding, particularly can automatic mobile screening glass and the eye guard tool that works asynchronously with argon arc welding.
Background technology
When argon arc welding, must be with protective mast, it is facial to be used for protection, particularly eyes.Existing protective mast is made up of a black shell and a protective eye lens that can stir.During welding, the staff gets and earlier protective eye lens is rolled up, and behind the aligning welding position, vacates a hands protective eye lens is turned down, and restarts welding machine, carries out welding job, after having welded, again protective eye lens is rolled up, and repeats above work.So operation brings great inconvenience to the staff, and inefficiency so the somebody does not wear protective mast work for figure is convenient, causes face and ocular damage.On existing for addressing the above problem " the automatic safety visor of argon arc welding machine " (patent No. 200420061604) face shield automatic catch arc mechanism is arranged, automatic catch arc mechanism comprises: motor M, the gear of motor shaft overcoat, tooth bar with gears engaged, the fixedly connected screening glass frame in tooth bar lower end, a slice colour light filter sheet glass is installed in the screening glass frame, the dual-side fixed block of screening glass frame, the dual-side of screening glass frame is with chute, the power supply of motor in switch connects argon arc welding machine, spring connects screening glass frame and last fixed leg.It utilizes motor rotate to drive the screening glass frame and moves down and block the welding arc light, utilizes the pulling force of spring to make on the screening glass frame and retracts the position.Its structure is complicated.
Summary of the invention
The purpose of this utility model aims to provide a kind of simple in structure, easy to operate, and the order tool is protected in working efficiency height, the synchronous automatic control of the argon arc welding that welding quality is good.
The implementation of this utility model purpose is, the order tool is protected in the synchronous automatic control of argon arc welding, the protuberance of cam rail 11 snaps in 7 four jiaos of protective eye lens recessed the wheel in 6 the groove, protective eye lens 7 links to each other with tooth bar 4, gear 3 engagements on tooth bar 4 and the motor 2, tooth bar 4 upper and lower both sides cards have recessedly takes turns 12, and the protuberance of cam rail 1 snaps in recessed the wheel in 12 the groove, there is Magnet 5 the tooth bar upper end
Normally-closed contact, the 1SJ of motor 2 one termination magnetic switch 1TJ
2Normally opened contact, the normally closed point of a termination magnetic switch 2TJ, 1SJ
2Connect the unidirectional current positive pole, 1SJ
1Connect the unidirectional current negative pole, relay 2SJ one termination unidirectional current positive pole, the normal battle of a termination magnetic switch 2TJ, relay 1SJ one termination unidirectional current negative pole, an end connects the unidirectional current positive pole by the argon arc welding K switch.
This utility model drives tooth bar 4 by the gear on the motor 23 and moves upward, when the Magnet 5 of upper end arrives spacing magnetic switch 1TJ, motor quits work, the staff aims at pad, start the argon arc welding switch, tooth bar moves downward, when Magnet arrives magnetic switch 2TJ, motor quits work, and argon arc welding is started working.
This utility model is simple in structure, easy to operate, high efficiency, welding quality are good, can effectively protect eyes not injured by arc light.

The specific embodiment
With reference to Fig. 1,2,3,4,5, this utility model by protective eye lens 7 and four jiaos recessed take turns 6, the gear 3 on the cam rail 11, tooth bar 4, motor 2, the Magnet 5 of tooth bar upper end etc., control circuit is formed.
When using this utility model, motor 2 drives tooth bar 4 by the gear on it 3, recessed 12 protuberances along cam rail 1 of taking turns that block tooth bar 4 upper and lower both sides move upward, tooth bar 4 moves upward, the Magnet 5 that moves to the upper end arrives the position of magnetic switch 1TJ8, and 7 four jiaos of protective eye lens recessed taken turns 6 and moved up to position shown in Figure 4 along the protuberance of cam rail 11 thereupon, and motor 2 quits work, staff's eyes can accurately be aimed at pad under the blocking who does not have protective eye lens.
Start the argon arc welding K switch, relay 1SJ
1, 1SJ
2The normal closure of making war, gear 3 on the motor 2 drives recessed 12 protuberances along cam rail 1 of taking turns that block tooth bar 4 upper and lower both sides and moves downward, tooth bar 4 moves downward, the Magnet 5 that moves to the lower end arrives the position of magnetic switch 2TJ9,7 four jiaos of protective eye lens recessed taken turns 6 and moved downward 10 places, position to Fig. 1 along the protuberance of cam rail 11 thereupon, and the normally closed point of 2TJ disconnects, and motor quits work, the 2TJ closure of often making war, argon arc welding is started working.
