Description
Technical Field
The utility model relates to mechanical equipment, concretely relates to high frequency machine contact device.
Background
The upper contact of the existing high-frequency machine contact device is connected with an output copper strip, the lower contact of the existing high-frequency machine contact device is connected with a high-frequency power supply, and when an operator works, an ejector rod jacks the lower contact and closes the upper contact, so that the high-frequency machine works.
Referring to fig. 1 and 2, a conventional high frequency machine contact device includes an upper contact 10 and a lower contact 20, the upper contact 10 is fixed in position, the upper contact 10 is connected with an output copper strip 30, the lower contact is connected with a high frequency power supply (only a wire 40 connected with the high frequency power supply is shown in the figure), the lower contact 20 is formed by connecting a thick copper sheet 22 and a soft copper sheet 21, wherein the soft copper sheet 21 is connected with the high frequency power supply and fixed on a base, and the thick copper sheet 22 is closed with the upper contact 10 when being jacked up by a jacking rod 50. During operation, under frequent actions, the soft copper sheet 21 is broken, which causes equipment failure and reduces production efficiency.
SUMMERY OF THE UTILITY MODEL
In view of the above, the inventor has conducted an in-depth analysis on the conventional high-frequency machine contact device, and found that the soft copper sheet is broken because the contact point is formed by connecting a thick copper block and a soft copper sheet, the base is fixed in position, and under frequent actions, stress is generated between the soft copper sheet and the base, and the stress can easily break the soft copper sheet under frequent actions.
In order to solve the technical problem, an object of the utility model is to provide a high frequency machine contact device, it can realize no matter how frequent use, and the contact can not break down, promotes production efficiency's technological effect.
The adopted technical scheme is as follows:
a high-frequency machine contact device comprises an upper contact and a lower contact, wherein the upper contact comprises a first upper contact and a second upper contact which are opposite at intervals, the first upper contact is connected with an output copper strip, the second upper contact is connected with a high-frequency power supply, and the lower contact is a conducting strip; and the lower contact is fixed with a mandril, and when the mandril is jacked up, the lower contact is closed with the upper contact.
Further, the conducting strip is a copper sheet.
The beneficial effects of the utility model reside in that:
the lower contact that comprises two copper sheets that differ in thickness has not been had, the utility model discloses a lower contact comprises a copper sheet to no matter realize many frequent uses, the contact can not break down, has promoted production efficiency's technological effect.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only preferred embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 3 and 4, a high frequency machine contact device includes an upper contact 100 and a lower contact 200, the upper contact 100 including a first upper contact 101 and a second upper contact 102 which are spaced apart and opposed to each other. The first upper contact 101 and the second upper contact 102 can still be fixed relative to each other, for example on a radio-frequency machine support (not shown). The first top contact 101 is connected to the output copper strip 300, and the second top contact 102 is connected to the high frequency power supply (only the wire 400 connected to the high frequency power supply is shown). The lower contact 200 is a conductive sheet, which can be an aluminum sheet, or a thick copper sheet used in the existing high-frequency machine contact device; the lower contact 200 is fixed with a push rod 500, that is, the push rod 500 is fixed under the thick copper sheet, and a power device, such as a power cylinder (not shown), is arranged under the push rod, and when the push rod 500 is pushed up by the power cylinder, the lower contact 200 is closed with the upper contact 100.
When the ejector rod is ejected, the lower contact and the upper contact are closed, namely, the work is started. When the power supply works, the high-frequency power supply is communicated with the upper contact output copper strip through the lower contact to output power.
The utility model discloses a design benefit part lies in, to the ingenious setting of upper and lower contact, has produced unexpected technological effect.
The lower contact of the existing high-frequency machine contact device is composed of two copper sheets with different thicknesses, and the two copper sheets with different thicknesses can generate stress under frequent actions, and the stress can easily cause the breakage of a soft copper sheet (namely a thin copper sheet).
The utility model discloses be divided into two with the top connection point, control the relative setting in interval, with the function redistribution, output copper strips is connected to the first top connection point, and high frequency power is connected to the second top connection point, and the bottom connection point just so can only be a thick copper sheet, just so can solve the problem of stress.
Because the stress problem is avoided, no matter how frequently the contact is used, the contact does not break down, and the technical effect of production efficiency is improved.
The above detailed description is only for the purpose of illustrating the practical embodiments of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent embodiments or modifications that do not depart from the technical spirit of the present invention are intended to be included within the scope of the present invention.
