The control device is used for controlling the reverse gear lamp of the engineering machine to be switched on or switched off, the pressing cover is riveted on the inner flanging of the shell, the pressing cover dislocation caused by overlarge working pressure of a product is effectively prevented, the pressure resistance of the product is improved, the service life of the product is stabilized, and the problems in the prior art are solved.
Description
Technical Field
The utility model relates to a high-voltage switch gland riveting set belongs to mechanical device technical field.
Background
The high-voltage switch gland is riveted through the interference fit of the gland and the size of the shell, the gland is tightly pressed into the inner cavity of the shell, and after riveting, when the working pressure of the high-voltage switch exceeds the set working pressure, the gland is easily separated from the inner cavity of the shell, so that the function failure of a product is caused.
At present, a high-voltage switch gland is riveted as shown in fig. 1, the outer diameter of the pressure switch gland 3 is in interference fit with the size of an inner cavity of a shell 5, and the gland 3 is crimped in the inner cavity of the shell 5. When the high-voltage switch assembly is assembled, the push rod 2 is placed in a hole of the gland 3, the diaphragm 4 is placed in a sealing groove of the gland 3, the assembled gland sub-assembly is placed on the positioning die, then the inner cavity of the shell 5 is sleeved downwards into the positioning die, and the gland 3 is pressed into the shell 5 through the press machine. The gland 3 of the high-voltage switch is in interference fit with the inner cavity of the shell 5 and is pressed in the shell 5, so that the phenomenon that the gland 3 is loosened is easily caused, and the faults that the high-voltage switch has poor pressure resistance and the switch performance fails are caused.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model aims to provide a high-voltage switch gland riveting set has solved the problem that appears among the prior art.
High-voltage switch gland riveting set, including the high-voltage switch casing, the inside boss that is equipped with of high-voltage switch casing is equipped with gland, push rod and diaphragm in the inner chamber of high-voltage switch casing, on gland and push rod placed the diaphragm for overall structure, the boss of high-voltage switch casing inner chamber was equipped with the turn-ups with the position that the gland is fixed, the inside turn-ups riveting of high-voltage switch casing fixes the gland.
Furthermore, the integral structure of the diaphragm, the gland and the push rod is riveted and fixed through the turned edge inside the high-voltage switch shell.
Further, the diaphragm is placed in a sealing groove of the high-voltage switch shell.
Further, the push rod is installed in the gland hole.
Compared with the prior art, the utility model, following beneficial effect has:
high-voltage switch gland riveting set for the control of engineering machine speed in reverse lamp switch-on or disconnection, the inside turn-ups riveting gland of casing effectively prevents because of the gland dislocation that product operating pressure too big leads to, promotes product pressure resistance, the life of stabilizing switch product has solved the problem that exists among the prior art.

Detailed Description
The invention will be further described with reference to the following drawings and examples:
example 1:
as shown in fig. 1-3, high-voltage switch gland riveting set, including high-voltage switch casing 5, the inside boss 1 that is equipped with of high-voltage switch casing 5 is equipped with gland 3, push rod 2 and diaphragm 4 in the inner chamber of high-voltage switch casing 5, on gland 3 and push rod 2 placed diaphragm 4 for overall structure, boss 1 and the fixed position of gland 3 of 5 inner chambers of high-voltage switch casing were equipped with the turn-ups, the inside turn-ups riveting of high-voltage switch casing 5 fixed gland 3.
The integral structure of the diaphragm 4, the gland 3 and the push rod 2 is riveted and fixed through the turned edge inside the high-voltage switch shell 5.
The membrane 4 is placed in a sealing groove of the high-voltage switch housing 5.
The push rod 2 is arranged in the hole of the gland 3.
The working principle of the embodiment is as follows: the gland 3 is riveted and fixed by an internal flanging of the pressure switch shell 5, as shown in part B of figure 2.
When the high-voltage switch assembly is assembled, the diaphragm 4 is placed in a sealing groove of the high-voltage shell 5, the push rod 2 is installed in a hole of the gland 3, and then the gland 3 is placed on the diaphragm 4; and (3) placing the high-voltage switch shell 5 assembly provided with the diaphragm 4, the gland 3 and the push rod 2 on a riveting lower die, and flanging and fixing the gland 3 fixing part of the inner cavity of the high-voltage switch shell 5 by using a special die. The inside turn-ups of high-voltage switch casing 5 are riveted and fixed gland 3. Under the condition of not influencing the assembly of other parts, the working life of the high-voltage switch can be prolonged, and the pressure resistance of the gland 3 can reach 30 MPa.
Adopt above to combine the drawing description the utility model discloses a high pressure switch gland riveting set, internal turn-ups riveting gland effectively prevents because of the too big gland dislocation that leads to of product operating pressure, promotes product pressure resistance, and the life of stabilizing switch product has solved the problem that exists among the prior art. The present invention is not limited to the embodiments described, but rather, variations, modifications, substitutions and alterations from the embodiments described herein are possible without departing from the spirit and scope of the invention.
