Detailed Description

As shown in FIG. 1, a connector for a disc spring is used in a work place requiring adjustment of the pitch of a disc spring group. The connector for the belleville springs comprises two groups of belleville spring groups 10 which are arranged in parallel, wherein an upper pressing plate 20 and a lower pressing plate 30 are respectively arranged at the upper end and the lower end of each belleville spring group 10. A guide rod 40 penetrates through the inner ring of the belleville spring group 10, the top end of the guide rod 40 abuts against the bottom of the upper pressure plate 20, specifically, a waist-shaped guide groove 21 with the width matched with the diameter of the guide rod 40 is arranged on the upper pressure plate 20, the top end of the guide rod 40 extends into the guide groove 21, the guide rod 40 can translate in the guide groove 21, and the guide groove 21 plays a role in guiding and limiting the movement of the guide rod 40. The bottom end of the guide rod 40 penetrates through the lower pressing plate 30 and the pressing cap, the pressing cap is in interference fit with the guide rod 40, the lower pressing plate 30 is fixed on a rack or other fixing parts, the upper pressing plate 20 is in a free state in the height direction, and the upper pressing plate 20 presses the butterfly spring group 10; the two guide rods 40 are adjusted in position and the bottom ends thereof can be fixed to a rigid structure such as a table or a housing. The lower press plate 30 is provided with a kidney-shaped hole 31 for the guide rod to pass through, and the horizontal position of the guide rod 40 in the kidney-shaped hole 31 can be adjusted, so that the distance between the two groups of belleville spring groups 10 can be adjusted through the kidney-shaped hole 31, and then the guide rod is fixedly arranged on a corresponding structural body.

The pressing cap comprises a first pressing cap 50 and a second pressing cap 60, referring to fig. 1 and fig. 2, an adjusting block 51 is welded on the side wall of the first pressing cap 50, a horizontal threaded hole 511 is formed in the adjusting block 51, a connecting rod 80 is connected with the threaded hole 511 in an internal thread mode, and the installation depth of the connecting rod 80 in the threaded hole 511 can be changed correspondingly along with the change of the distance between the two groups of belleville spring groups 10. The other end of the connecting rod 80 is screwed with the second pressing cap 60, specifically, a positioning hole 61 with internal threads is arranged on the side wall of the second pressing cap 60, and the end of the connecting rod 80 extends into the positioning hole 61 and is screwed with the positioning hole 61, so that the positioning hole 61 and the adjusting block 51 fix the end of the connecting rod 80 at the same time. A plurality of positioning holes 61 may be provided on the sidewall of the second cap 60 to facilitate the assembly of the connecting rod 80. The two gland caps are connected by a connecting rod 80, thereby connecting the two sets of belleville spring sets 10 and keeping their spacing fixed.

The outer diameter of the press cap is greater than the length of the kidney hole 31, so that the press cap can be stably pressed against the bottom surface of the lower press plate 30. The buffer gasket 90 is installed between the pressing cap and the lower pressing plate 30, and the buffer gasket 90 can reduce noise generated by frequent collision between the pressing cap and the lower pressing plate 30 when the belleville spring group 10 extends and contracts.

In order to improve the connection strength between the connecting rod 80 and the pressing cap, a connecting block 52 with a diameter larger than that of the adjusting block is welded on the side wall of the adjusting block 51, an extension spring 70 is mounted on the connecting rod 80, two ends of the extension spring 70 are respectively welded on the side walls of the connecting block 52 and the second pressing cap 60, the end part of the extension spring 70 can be fixed on the connecting block 52 and the second pressing cap 60 by adopting a clamping hook, a screwing mode and the like, the extension spring 70 can oppositely tighten the first pressing cap 50 and the second pressing cap 60, and the connecting rod 80 is prevented from being separated from the pressing cap due to insufficient meshing degree of threaded connection between the adjusting block 51 or the positioning hole 61. The diameter of the connecting block 52 is larger than that of the adjusting block 51, so that the extension spring 70 can be conveniently installed and fixed.

The installation method of the connector comprises the following steps: two ends of a connecting rod 80 are respectively arranged in the positioning holes 61 of the adjusting block 51 and the second pressing cap 60, the installation depth of the connecting rod 80 in the adjusting block 51 is adjusted according to the distance between the two groups of belleville spring groups 10 to be installed, the extension spring 70 is sleeved on the connecting rod 80, two ends of the extension spring are respectively and fixedly arranged on the connecting block 52 and the second pressing cap 60, and then the two guide rods 40 are respectively and tightly inserted into the two pressing caps, so that the distance between the two guide rods 40 is kept constant. After the two guide rods 40 pass through the two waist-shaped holes 31 on the lower pressure plate 30, the two groups of belleville spring groups 10 are respectively sleeved on the two guide rods 40, and then the upper pressure plate 20 is arranged at the tops of the guide rods 40, so that the tops of the guide rods 40 extend into the guide grooves 21. When the distance between the two groups of belleville spring groups 10 needs to be adjusted, the connecting rod 80 is screwed, and the installation depth of the connecting rod in the threaded hole of the adjusting block 51 is changed. When the belleville springs are pressed, the distance between the two groups of belleville spring groups 10 is always kept unchanged.
