Description

Technical Field

[0001] The utility model relates to the technical field of disc springs, in particular to a disc spring with positioning. Background Art

[0002] The disc spring is a special spring that is conical in the axial direction and bears load. After being deformed under the load, it stores a certain amount of potential energy. When the bolt becomes loose, the disc spring releases part of the potential energy to maintain the pressure between the flange connections to meet the sealing requirements. The stress distribution of the disc spring decreases evenly from the inside to the outside, which can achieve the effect of low stroke and high compensation force.

[0003] For example, the announcement number is: CN208010819U (named as a disc spring with positioning), which includes a multi-layer spring group stacked coaxially, each layer of the spring group includes an upper disc spring sheet and a lower disc spring sheet, the outer edge of the upper disc spring sheet is in conflict with the outer edge of the lower disc spring sheet, the inner edge of the upper disc spring sheet is directly opposite to the lower disc spring sheet and is provided with an annular upper positioning seat, and the inner edge of the lower disc spring sheet is directly opposite to the upper disc spring sheet and is provided with an annular lower positioning seat; the lower end of the upper positioning seat is provided with an annular mounting groove, and the mounting groove extends along the height direction of the upper positioning seat, the lower positioning seat is movably sleeved in the mounting groove, and a telescopic spring with a spiral structure is arranged in the mounting groove, the upper end of the telescopic spring is fixed to the top of the mounting groove by a fastener, and the lower end of the telescopic spring presses against the upper end of the lower positioning seat. The utility model provides an upper positioning seat and a lower positioning seat, and the lower positioning seat is sleeved in the installation groove of the upper positioning seat to position the upper disc spring piece and the lower disc spring piece, so that the upper disc spring piece and the lower disc spring piece are installed in a matched manner, the installation is stable, and no displacement occurs during use. Moreover, through the arrangement of the telescopic spring, the telescopic spring is compressed and deformed, and a supporting and buffering effect is played on the upper disc spring piece and the lower disc spring piece, thereby improving the elasticity.

[0004] The disc spring is composed of a plurality of disc plates into a spring structure by means of a positioning assembly structure. However, the structure of the disc plates is relatively complicated, which increases the manufacturing cost of the disc spring and causes inconvenience in the positioning and assembly operation of the disc spring. Therefore, we provide a disc spring with positioning. Utility Model Content

[0005] The purpose of the utility model is to provide a disc spring with positioning, so as to solve the problem that the existing disc spring proposed in the above background technology combines multiple disc plates into a spring structure through a positioning assembly structure, but the structure of the disc plates is relatively complicated, which makes the manufacturing cost of the disc spring high and causes inconvenience in the positioning and assembly operation of the disc spring.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a disc spring with positioning, comprising a mounting base, the upper end of the mounting base is integrally formed with a supporting base, the upper end of the supporting base is integrally formed with a supporting tray, a bearing platform is arranged above the supporting tray, and disc-shaped pieces are stacked and arranged on the upper end of the bearing platform;

[0007] Also includes:

[0008] A support pole is welded and arranged at a position between the load-bearing platform and the supporting plate, and a hollow inner cavity is arranged inside the support pole, and an upper end and a lower end of the hollow inner cavity are connected and provided with a movable perforation and a filling inner hole respectively;

[0009] A threaded bushing tube is fixedly arranged inside the filling inner hole by means of nail-free glue, and a threaded push rod is movably arranged inside the threaded bushing tube, and a supporting round seat is integrally formed on the upper end of the threaded push rod;

[0010] The positioning rod is arranged at the outer position of the disc-shaped piece. There are six positioning rods, and the outer wall of the disc-shaped piece is in contact with and connected to the six positioning rods.

[0011] Preferably, a return spring is fixedly provided at the lower end of the positioning upright pole by means of nail-free glue, the return spring is located inside the hollow inner cavity, and the bottom of the return spring abuts against the supporting round seat.

[0012] Preferably, six supporting uprights and six threaded push rods are provided, and the six supporting uprights and the six threaded push rods correspond one-to-one to the six positioning uprights, respectively.

[0013] Preferably, the movable through hole and the filling inner hole are respectively integrated with the carrying platform and the supporting tray.

[0014] Preferably, the six positioning rods pass through the movable through-holes and extend into the interior of the hollow inner cavity.

[0015] Preferably, a screw cap is integrally formed at the lower end of the threaded push rod, and the size of the screw cap is larger than the caliber of the threaded bushing tube.

[0016] Preferably, the disc-shaped pieces form a group of two, and two adjacent disc-shaped pieces are stacked up and down.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The utility model stacks and places a plurality of disc-shaped pieces in pairs on the upper end position of the bearing platform so that six positioning uprights can position the disc-shaped pieces, thereby vertically positioning and stacking the plurality of disc-shaped pieces, avoiding displacement of the disc-shaped pieces when stacking and stacking, without changing the structure of the disc-shaped pieces, and having simple stacking operation. The height of the positioning uprights can be adjusted according to the number of disc-shaped pieces to be stacked as required, and during the adjustment process, the screw cap is rotated to drive the threaded push rod to guide along the threaded bushing tube, so that the supporting round seat lifts the reset spring and drives the positioning uprights to be raised and lowered along the movable through-hole, thereby overcoming the problem that the existing disc spring combines a plurality of disc-shaped pieces into a spring structure through the positioning assembly structure provided, but the structure of the disc-shaped pieces is relatively complicated, which increases the manufacturing cost of the disc spring and causes the disc spring positioning and assembly operation to be inconvenient.

[0019] 2. The stacked disc sheets form a disc spring structure. When the disc spring contracts under pressure, the positioning rod is compressed synchronously. Under the action of the return spring, it penetrates the movable perforation and is inserted into the hollow inner cavity, so that the positioning structure can adapt to the contraction of the disc spring and contract synchronously, and the normal use of the disc spring is not affected while positioning.
