Description
Technical field
This utility model one welding protective cover eyeglass switching device shifter, relates to the switchable welding protective cover of a kind of eyeglass, belongs to security appliance field.Use in electrode welding process in particular to a kind of, eyeglass switching can be carried out fast, effectively can improve the device of weld job efficiency.
Background technology
At present, electric welding technology is widely used in each production field.The high light produced in electrode welding process can cause very big damage to the vision of people.Common electric welder's helmet eyeglass is filter glass, and electric welder, when welding work pieces, cannot see solder joint clearly through filter glass, by virtue of experience and can only feel, extremely easily cause welding error during striking.For avoiding welding error as far as possible, electric welder need adjust face shield continually when using current welding mask.During adjustment welding handle position, electric welder's helmet need be taken from face to see pad clearly and the position of adjustment welding handle by electric welder.During welding, electric welder needs again electric welder's helmet to be placed in face with anti glare anti static coatings.Constantly by face shield from face take from be placed in face and bring huge inconvenience to the electric welding work of electric welder.In some welding processes, Welder often causes welding error not in time because face is taken from or be placed in electric welder's helmet and causes damage to vision.Some existence on the market current have the electric welder's helmet protecting order effect and are roughly divided into two classes, that eyeglass switches class and the light-operated variable color class of eyeglass respectively, protection effect is also not obvious, can not be timely and effective and prevent high light to the damage of electric welder's vision comparatively easily in welding process.The eyeglass switching class electric welder's helmet braking effect of current existence is poor, and eyeglass is long for switching time, cause eyeglass switch not in time thus cause high light to hinder eye, and eyeglass switching mode easily causes facial injuries.The eyeglass of light-operated variable color class electric welder's helmet be easily subject to temperature, high light, electric arc factor impact thus cause induction sensitivity level significantly to reduce, produce variable color error, larger damage caused to eyes.
Summary of the invention
In order to improve above-mentioned situation, this utility model is a kind of to be welded protective cover eyeglass switching device shifter and provides and a kind ofly to use in electrode welding process, can switch the protective cover of screening glass fast.The timely switching of eyeglass can be realized in electrode welding process, can effectively improve weld job efficiency.
This utility model one welding protective cover eyeglass switching device shifter is achieved in that this utility model one welding protective cover eyeglass switching device shifter is made up of mask device, bracing or strutting arrangement and switchover apparatus.Mask device is made up of forehead lid, face shield and spiracle, and spiracle is on face shield, and forehead lid is placed in face shield top.Bracing or strutting arrangement is made up of support frame, transparent glasses lens, screening glass, auxiliary moving slide rail and main shifting sledge.Support frame is placed on face shield, and is positioned at above spiracle, and transparent glasses lens is placed on support frame, and main shifting sledge and auxiliary moving slide rail are placed in support frame both sides respectively, and screening glass is placed between main shifting sledge and auxiliary moving slide rail.Switchover apparatus is by brace, servomotor, line shaft, draught line, winding roller, spacing hole, hollow sleeve, limited block, groove, gag lever post, stopper slot, traction projection, retaining collar, movable plate, spring and gripper shoe composition, servomotor is placed in forehead and covers, line shaft is placed on servomotor, winding roller is placed on line shaft, gripper shoe is placed on face shield, hollow sleeve is vertically placed in the middle part of gripper shoe, gag lever post is vertically placed in gripper shoe, and parallel with hollow sleeve, spacing hole is placed in the middle part of hollow sleeve, hollow sleeve side has groove, limited block is placed on face shield, and be positioned at hollow sleeve both sides, retaining collar is placed on hollow sleeve, traction projection is placed on retaining collar inwall, and insert in the groove of hollow sleeve side, draught line one end curls on winding roller, the other end is connected with traction projection through spacing hole, retaining collar one is placed on movable plate, movable plate is connected with screening glass by brace.Movable plate has stopper slot, and movable plate is placed on gag lever post by stopper slot, and spring housing is placed on gag lever post, and one end is placed in gripper shoe, and the other end is connected to below movable plate.
During use, when needs eyeglass switches time, only need to control servomotor to rotate forward, servomotor drives winding roller to rotate by line shaft, winding roller is wound around draught line and up moves, draught line drives the traction projection on retaining collar to move along the groove in hollow sleeve, and then make retaining collar increase along hollow sleeve, retaining collar drives movable plate up to move along gag lever post, spring elongation now between movable plate and gripper shoe, screening glass is driven by brace by movable plate, screening glass is up moved along the main shifting sledge of both sides and auxiliary moving slide rail, transparent glasses lens below screening glass, can normal operation use.When needs weld time, only need to control servomotor reversion, due to the restoring force of spring, spring pulls movable plate to move down along gag lever post, screening glass is driven by brace by movable plate, screening glass is moved down along the main shifting sledge of both sides and auxiliary moving slide rail, can screening glass be used.Meanwhile, movable plate drives retaining collar to move down along hollow sleeve, and the traction projection on retaining collar pulls draught line constantly to move down, and winding roller is unwrapping wire slowly, and draught line is returned to original state.So repeatedly, reach the timely switching realizing eyeglass in electrode welding process, effectively can improve the object of weld job efficiency.
