- the present invention relates to a holder for a spot welding tip dresser, and more particularly, a spot welding tip dresser capable of adjusting the amount of cutting to adjust the protrusion of the cutter to center the spot welding tip of the spot welding robot and to adjust the cutting amount of the tip. Relates to a holder.
- spot welders used for welding automotive panels, etc. are resistance welders, in which upper and lower electrode tips press both sides of a metal plate, and then weld through electric current.
- the element that determines the amount of cut per revolution of the tip dresser is determined according to the degree of protrusion of the cutter protruding from the guide surface of the holder and the pressing force of the welding gun when dressing the tip.
- the conventional tip dresser holder is fixed to the diaphragm 113 so that the cutter 120 protrudes to a constant height. That is, when the dressing pressing force of the welding gun is higher than the set pressure, the welding gun presses the tip above the set pressure, and the tip is excessively cut, which causes a problem that the tip needs to be frequently replaced because the cutting amount of the tip is large. In addition, when the dressing pressing force of the welding gun is lower than the set pressure, the force of the welding gun pressing the tip is weak, so that the tip is not cut properly, and the nugget of the tip is unevenly formed, so that the welding quality is deteriorated or the cutting time is long. Occurs. Therefore, as the time taken for frequently changing or cutting the tip is delayed, the overall welding work time becomes long, and the maintenance cost increases due to frequent tip replacement.
- the present invention has been made in order to solve the above problems, it is possible to set the cutting amount of the tip by installing an adjust liner that can adjust the degree of protrusion of the cutter to be used for both air gun and servo gun, It is an object of the present invention to provide a holder for a spot welding tip dresser that can adjust the amount of cutting to form a constant nugget on the tip by forming the circumference of the guide surface at an angle between 185 ° and 200 ° so as not to deviate from the guide surface. .

- the holder body may be formed with an insertion groove into which the adjust liner is inserted between the guide surface and the guide surface so that the adjust liner is firmly fixed to the holder body.
- the adjust liner can be replaced by constantly forming the entire thickness of the adjust liner so as to adjust the protruding length of the cutter, or by forming one surface on which the cutter is in close contact with the cutter.
- the clamp may be formed with a guide groove on one surface such that the adjust liner is more firmly fixed to the holder body.
- the holder body easily discharges the chip in which the spot welding tip is cut, and the circumference of the guide surface at an angle of 185 ° or more and 200 ° or less with respect to the center so that the spot welding tip does not deviate from the center of the guide face. Can be formed.
- the clamp may be provided with a release preventing jaw at one end of the clamp to prevent the adjust liner and the cutter from flowing from the holder body.
- the holder for the spot welding tip dresser which can adjust the cutting amount according to the embodiment of the present invention provides a constant cutting amount by installing an adjust liner that adjusts the degree of cutter protrusion even if the pressing force is different regardless of the air gun or the servo gun. It is effective to maintain.
- an adjust liner that adjusts the degree of cutter protrusion even if the pressing force is different regardless of the air gun or the servo gun. It is effective to maintain.
- the circumference of the guide surface at an angle between 185 ° and 200 ° or less to prevent the tip from leaving the guide surface, there is an effect that the nugget of the tip can be uniformly formed. This prevents the tip from being cut excessively, thereby reducing maintenance costs, while cutting the tip quickly and consistently forming the nugget of the tip to improve welding quality and also reduce the overall welding time. have.

- the above-described angle of ⁇ is formed at an angle between 185 ° and 200 ° or less, and the angle of ⁇ is preferably formed at 190 ° so that the chip generated by cutting the tip is easily discharged. Detailed description thereof will be described later.
- the adjust liner 20 is formed to a predetermined thickness t so as to be inserted into the insertion groove 12 of the holder body 10, and is divided into a seating portion 21 and an insertion portion 22.
- the seating portion 21 is a portion on which the cutter 30 is seated
- the insertion portion 22 is formed at the right side and the rear side of the seating portion 21, and a portion thereof is stepped with the seating portion 21. Accordingly, the adjust liner 20 is inserted into the insertion groove 12 to set the degree of protrusion of the cutter 30. Detailed description thereof will be described later.
- the cutter 30 is well known and known, and is well represented in the Utility Model Registration No. 0277041 or 0439234, and a detailed description thereof will be omitted.
- the clamp 40 has a coupling portion 41 which is bent and coupled to the coupling surface 13 of the holder body 10 so that the cutter 30 is inserted between the holder body 10 and the clamp 40.
