Moreover, such phrases are not intended to refer to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to effect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.
Where certain terms are used in the specification and following claims to refer to particular components or features, those skilled in the art will understand that various terms or numbers may be used by a skilled user or manufacturer to refer to the same component or feature. This specification and the claims that follow do not intend to distinguish between components or features that differ in name but not function. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to. In addition, the term "coupled" is intended to include any direct or indirect coupling. Indirect electrical connection means include connection by other means.
As shown in fig. 1 and 2, the stud welding gun 10 of the present invention includes a welding gun main body 100 and a welding gun head 200, wherein the welding gun head 200 is connected to the welding gun main body 100, and the welding head 200 is a direct welding position. The welding gun head 200 comprises a clamping jaw 210, a clamping jaw support 220 and a clamping jaw air cylinder 230, wherein the clamping jaw 210 and the clamping jaw air cylinder 230 are respectively connected with the clamping jaw support 220, and the clamping jaw air cylinder 230 is used for driving the clamping jaw 210 to move.
Wherein, clamping jaw cylinder 230 includes cylinder sheetmetal 231, and cylinder sheetmetal 231 is connected with clamping jaw support 220, the utility model discloses a stud welding gun 10 still includes insulating part 300, and insulating part 300 presss from both sides and establishes between cylinder sheetmetal 231 and clamping jaw support 220 for keep cylinder sheetmetal 231 and clamping jaw support 220 mutual insulation.
When the stud gun 10 is in operation, the welding slag enters the inside of the jaw cylinder 230 and adheres to the cylinder metal piece 231 of the jaw cylinder 230. In the welding process, if there is no insulation between the cylinder plate 231 and the weld nail, welding slag having a large rate may be welded to the cylinder plate 231 during welding, resulting in a resistance to movement of the cylinder plate 231. Therefore, the welding slag is not introduced into the welding gun, which affects the service life of the welding gun, because the welding slag is inevitable, and the welding slag is welded to the cylinder metal sheet 231 due to the lack of insulation between the cylinder metal sheet 231 and the welding nail, which is the reason for the short service life of the welding gun.
By measuring the electrical resistance between the various components of torch head 10, it is also possible to find conduction between all the components, which results in current flowing through the entire assembly during welding. When the welding slag is attached to the cylinder sheet metal 231, energy is generated under the action of the current resistor, the welding slag is melted instantly, after the current disappears, the energy disappears, the welding slag is cooled and welded on the cylinder sheet metal 231, and movement clamping stagnation is caused because no gap exists between the two cylinder sheet metals 231 during movement.
The utility model discloses a set up insulating part 300, the welding of welding slag problem on cylinder sheetmetal 231 when effectively having solved the welding has increased clamping jaw cylinder 230's life.
The insulating member 300 is, for example, an insulating film with a thickness of 0.1mm, which not only ensures the insulating effect between the cylinder metal sheet 231 and the jaw holder 220, but also enables the cylinder metal sheet 231 and the jaw holder 220 to be in relatively close contact without a large gap.
As shown in fig. 2, the cylinder plate 231 and the jaw holder 220 are connected by a screw 400, and the insulating member 300 has a hole portion through which the screw 400 passes.
Wherein, the utility model discloses a stud welding gun 10 still includes insulating support bush 500, and clamping jaw support 220 includes bush hole 221, and insulating support bush 500 sets up in clamping jaw support 220's bush hole 221, and screw 400 passes insulating support bush 500 and is connected on cylinder sheetmetal 231.
Further, the insulating holder bushing 500 includes a burring 510, the bushing hole 221 includes a step 221a, the insulating holder bushing 500 is located in the bushing hole 221, and the burring 510 is carried on the step 221a of the bushing hole 221.
The cylinder metal sheet 231 includes a counter bore 231a, the counter bore 231a corresponds to the bushing hole 221, and the counter bore 231a and the bushing hole 221 together form a space for accommodating the insulating holder bushing 500. Wherein, the flanging part 510 at the top of the insulating support bush 500 is erected on the step part 221a of the bush hole 221a, and the bottom of the insulating support bush 500 extends into the counter bore 231. The screw 400 is connected to the cylinder sheet 231 through the insulating holder bushing 500 and the insulating member 300 in contact therewith, and the screw 400 does not contact the jaw holder 220, so that no current flows into the cylinder sheet 231 during welding. Use the utility model discloses can reduce by a wide margin and trade the rifle number of times, the down time reduces, has increased machining efficiency.
Wherein, insulating support bush 500 is ceramic member, and insulating effectual to the hardness is high. The screw 400 may also be provided as an insulating screw, further improving the insulating properties. Of course, the screw 400 may be a common metal screw, so as to avoid the problem that the screw is not hard enough and may be separated from the screw after being used for a period of time.
Naturally, the present invention can be embodied in many other forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be made by one skilled in the art without departing from the spirit or essential attributes thereof, and it is intended that all such changes and modifications be considered as within the scope of the appended claims.
