Abstract

The utility model relates to a contact-type electric-control-guide thread cleaning machine, which comprises a base. An electric control motor device which consists of a motor, a transformer, an alternating-current contactor, a diode and a contact travel switch which are electrically connected through conducting wires is installed on the base. A locking head is sheathed on the main shaft of the motor. A screw tap is installed on the locking head. A pushing plate is arranged at the front end of the motor and is slideably connected with a guide pin which is arranged on the base. A restoring spring is sheathed on the guide pin. A screw tap hole is arranged on the pushing plate. The pushing plate axially slides along the screw tap through the guide pin. A contact corresponding to the contact travel switch is arranged on the pushing plate. During use, an operator holds a part by two hands and the part pushes the pushing plate to move forwards under the drive of the screw tap. Since the part is placed stably and the thread cleaning power is stable, the situations that a nut is damaged and the screw tap is ruptured do not occur; and since the screw tap is horizontally installed and faces right to the operator and the operation is not limited by an operating space, threads of all parts with thread characteristics in any shape can be cleaned on the machine.

Description

The clear silk of the automatically controlled guiding of contact machine

Technical field

The utility model relates to a kind of clear silk machine, the clear silk of the automatically controlled guiding of especially a kind of contact machine.

Background technology

In the actual production operation, screwed parts have two kinds of processing modes: a kind of is to do tapping processing after boring on metallic element; Another kind is nut or bolt and body member to be welded together to realize product function on the parts that metal stamping is shaped, and cause screw thread that slight burns and distortion are arranged in welding process under the heavy current effect, and at remaining a little welding slag of thread surface and splash.In addition, all make face coat in most of parts use procedures and process, and after Parts Surface Coating, with the coating deposit, use the thread size precision to change in thread surface, if do not carry out again clear silk, will affect follow-up installation exercise.On screw thread and removing screw thread, welding slag splashes and the coating deposit in order to revise, portable clear machine, tapping machine or the manual clear silks of using during reality is produced more.With portable clear silk machine or manual clear silk, the clear silk of hand operated instrument in the time of a hand retaining element of operator, working strength is large, and generation efficiency is low; And the singlehanded clear inequality, firmly inharmonious of having an effect, fragile screw thread and screw tap, product rejection rate is high, production cost is high; Make fixture if aim at the part that needs clear silk, will increase production cost, extend manufacture cycle.With the clear silk of tapping machine, because of its screw tap vertical operation, and part to be fixed on the clear silk of ability on workbench, but various External Shapes are different, clear silk position, orientation be different, fixing, take out part and man-hour of wasting is disregarded, and can not satisfy the requirement of the multi-faceted clear silk of Same Part.

Summary of the invention

The purpose of the utility model just is to provide the clear silk of the automatically controlled guiding of a kind of contact machine, can effectively solve the problem that product rejection rate is high, production cost is high and production efficiency is low of existing clear silk equipment.

in order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: the clear silk of the automatically controlled guiding of contact machine, comprise support, be equipped with on support by motor, transformer, A.C. contactor, diode group and contact travel switch connect the electronically controlled motors device of composition by the wire electricity, be set with tapered end on the main shaft of motor, screw tap is housed on tapered end, it is characterized in that: the front end of motor is provided with push pedal, push pedal is slidably connected with the guide finger that is arranged on support, be set with back-moving spring on guide finger, push pedal is provided with the screw tap hole, push pedal endwisely slips along screw tap by guide finger, push pedal is provided with and the corresponding contact of contact travel switch.

beneficial effect: the utility model in use, operator's both hands are held part, part promotes push pedal and moves ahead under the drive of screw tap, because part is placed steadily, clear silk dynamical stability, can not cause damaging nut and screw tap fractures, and diode rectification protection is housed in circuit, can not cause motor to be damaged because load is excessive, screw tap is the horizontal level installation in addition, just in time in the face of the operator, without operating platform, be not subjected to the restriction of operating space, therefore no matter the part that is threaded characteristic of which kind of shape, after welding and coating, need not frock, the aids such as conveying, can easily complete silk work clearly on this equipment, thereby product percent of pass and production efficiency have effectively been improved, reduced production cost.The utility model is simple in structure, and is easy to operate, and production efficiency is high, and product percent of pass is high.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is circuit connection diagram of the present utility model.

The specific embodiment

as illustrated in fig. 1 and 2, the clear silk of the automatically controlled guiding of contact machine, comprise support 1, support 1 is provided with by motor 2, transformer 3, A.C. contactor 4, diode group 5 and contact travel switch 6 connect the electronically controlled motors device of composition by the wire electricity, be set with tapered end 7 on the main shaft of motor 5, screw tap 8 is housed on tapered end 7, the front end of motor 2 is provided with push pedal 9, push pedal 9 is slidably connected with the guide finger 10 that is arranged on support 1, be set with back-moving spring 11 on guide finger 10, push pedal 9 is provided with the screw tap hole, push pedal 9 endwisely slips along screw tap 8 by guide finger 10, push pedal 9 is provided with and the corresponding contact of contact travel switch.

Operation principle of the present utility model: use closure, the separation of two contact travel switches, control the rotating of motor.when clear silk machine start operation, the travel switch of controlling the motor forward is in closure state, operator's both hands are held part and are begun silk clearly, part moves ahead simultaneously with the screw thread drive push pedal of screw tap, the distance that the silk step is completed is walked to clearly in the push pedal of current line, will hit the stroke contact switch that closes the control motor reversal and make it closed, make motor reversal begin to move back silk by A.C. contactor, be arranged on the tension force of the stage clip on guide finger, push pedal and part retreat to complete move back the silk apart from the time, will hit the stroke contact switch that closes control motor forward and make it closed, motor is got back to the initial launch forward and is turned to.

Claims (1)

1. the clear silk of the automatically controlled guiding of contact machine, comprise support, be equipped with on support and connect the electronically controlled motors device that forms by motor, transformer, A.C. contactor, diode group and contact travel switch by the wire electricity, be set with tapered end on the main shaft of motor, screw tap is housed on tapered end, it is characterized in that: the front end of motor is provided with push pedal, push pedal is slidably connected with the guide finger that is arranged on support, be set with back-moving spring on guide finger, push pedal is provided with the screw tap hole, push pedal endwisely slips along screw tap by guide finger, and push pedal is provided with and the corresponding contact of contact travel switch.
