Description

Technical Field

[0001] The utility model relates to the field of disc springs, in particular to a 4-fold force disc spring. Background Art

[0002] Disc springs are also known as Belleville spring washers. Disc springs are conical disc-shaped. Unlike traditional springs, they have special functions. Their main features are large load, short stroke, small space required, convenient combination and use, easy maintenance and replacement, high economy and safety. They are suitable for precision heavy machinery with small space and large load. The best use range of their compression stroke is between 10% and 75% of their maximum compression stroke.

[0003] When the disc spring combination is subjected to a large force environment, multiple disc springs need to be stacked in order to withstand a larger load. However, when a large force load needs to be provided, many disc springs need to be combined together, and the movement stroke of the disc spring assembly will become very large. If only a smaller stroke is required, too many disc springs cannot be combined, but the load provided by each disc spring is very small.

[0004] Therefore, it is necessary to propose a 4-fold force disc spring to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a 4-fold force disc spring, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A 4-fold force disc spring comprises a disc spring sleeve, wherein a screw is installed in the inner cavity of the disc spring sleeve, a disc spring group is sleeved on the outer wall of the screw, and a nut is installed on the top of the screw.

[0008] Preferably, a gasket is provided at the top of the disc spring sleeve, a nut is threadedly connected to the top of the screw rod, the nut is threadedly connected to the top of the disc spring sleeve, and the gasket is provided between the nut and the top disc spring assembly.

[0009] Preferably, there are four disc spring groups, and the disc spring group includes a second sleeve, a third sleeve and a first sleeve.

[0010] Preferably, the second sleeve is fixedly connected to the top of the third sleeve, the first sleeve is fixedly connected to the bottom of the third sleeve, and a disc spring body is installed on the outer wall of the first sleeve, and each disc spring body includes six disc springs.

[0011] Preferably, force-bearing workpieces are symmetrically sleeved on both sides of the outer wall of the third sleeve, and the force-bearing workpieces are located between the second sleeve and the first sleeve. Top screws are symmetrically installed on the opposite sides of the force-bearing workpieces, and the other ends of the top screws extend into the inner cavity of the third sleeve.

[0012] Preferably, mounting grooves are symmetrically provided on the front and back sides of the outer wall of the disc spring sleeve, the mounting grooves are adapted to the size of the force-bearing workpiece, and the force-bearing workpiece is movably connected in the inner cavity of the disc spring sleeve via the mounting grooves. Beneficial Effects

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The 4-fold disc spring has four disc spring sets set on the outer wall of the screw. When the bottom of the screw is under pressure, the force will act on one end of the disc spring body through the other side of the bottom of the screw. At this time, the force can be transmitted to the disc spring set through the interaction inside the four disc spring sets through the stressed workpiece of each set, so that it can be lifted up a short distance.

[0015] 2. The 4-fold force disc spring can withstand a force of 400 kilograms while having a stroke of only 1.5 millimeters. It is suitable for situations where a small stroke has to withstand a large force. Each disc spring group is composed of a first sleeve, a second sleeve, a third sleeve, two force-bearing workpieces and two top screws. When the screw transmits the force to the bottom disc spring body, the force can be transmitted to the first sleeve through the interaction between the disc spring bodies. Then the first sleeve will squeeze the force-bearing workpiece. Since the force-bearing workpiece is connected to the disc spring sleeve, it can be driven to move upward at this time. At the same time, the force conditions of the four disc spring groups are the same, the structure is simple, and the movement stroke is very small while the disc spring is subjected to a large force.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-Figure 3 As shown, a 4-fold force disc spring includes a disc spring sleeve 5, a screw 6 is installed in the inner cavity of the disc spring sleeve 5, a disc spring group 4 is provided on the outer wall of the screw 6, a nut 1 is installed on the top of the screw 6, a gasket 2 is provided on the top of the disc spring sleeve 5, a nut 3 is threadedly understood on the top of the screw 6, the nut 1 is threadedly connected to the top of the disc spring sleeve 5, the gasket 2 is arranged between the nut 1 and the top disc spring group 4, there are four disc spring groups 4, the disc spring group 4 includes a second shaft sleeve 9, a third shaft sleeve 10 and a first shaft sleeve 8, the second shaft sleeve 9 is fixedly connected to the top of the third shaft sleeve 10, and the first shaft sleeve 8 is fixedly connected to the third shaft sleeve 10. At the bottom, a disc spring body 7 is installed on the outer wall of the first sleeve 8, each disc spring body 7 includes six disc springs, and force-bearing workpieces 12 are symmetrically sleeved on both sides of the outer wall of the third sleeve 10. The force-bearing workpieces 12 are located between the second sleeve 9 and the first sleeve 8, and top screws 11 are symmetrically installed on the opposite sides of the force-bearing workpieces 12. The other end of the top screw 11 extends into the inner cavity of the third sleeve 10, and mounting grooves 13 are symmetrically opened on the front and back sides of the outer wall of the disc spring sleeve 5. The size of the mounting grooves 13 and the force-bearing workpieces 12 are adapted, and the force-bearing workpieces 12 are movably connected in the inner cavity of the disc spring sleeve 5 through the mounting grooves 13.

[0022] The four disc spring groups 4 are sleeved on the outer wall of the screw 6. When the bottom of the screw 6 is subjected to pressure, the force will act on one end of the disc spring body 7 through the other side of the bottom of the screw 6. At this time, the force can be transmitted to the disc spring sleeve 5 through the interaction inside the four disc spring groups 4 through the force-bearing workpiece 12 of each group, so that it can be lifted up a small displacement. This disc spring can withstand a force of 400 kilograms while having a stroke of only 1.5 mm. It is suitable for situations where a small stroke has to withstand a large force. Each disc spring group 4 is composed of a first sleeve 8, a second sleeve 9, a third sleeve 10, two force-bearing workpieces 12 and two top screws 11. When the screw 6 transmits the force to the lowest disc spring body 7, the force can be transmitted to the first sleeve 8 through the interaction between the disc spring bodies 7. Then the first sleeve 8 will squeeze the force-bearing workpiece 12. Since the force-bearing workpiece 12 is connected to the disc spring sleeve 5, it can be driven to move upward at this time. At the same time, the force conditions of the four disc spring groups 4 are the same, the structure is simple, and the movement stroke is very small while the disc spring is subjected to a large force.

[0023] It should be noted that the utility model is a 4-fold disc spring. When in use, four disc spring groups 4 are sleeved on the outer wall of the screw 6, the nut 3 is threadedly connected to the top of the screw 6, the disc spring sleeve 5 is sleeved on the outer wall of the disc spring group 4 and the screw 6, the gasket 2 is placed on the top of the disc spring sleeve 5, and the nut 1 is installed before the whole can be used;

[0024] When the bottom of the screw rod 6 is stressed, the force will be transferred to the disc spring group 4 at the bottom. At this time, the disc spring body 7 will be stressed, and the disc spring body 7 will transfer the force to the first sleeve 8, which will squeeze the stressed workpiece 12. Since the stressed workpiece 12 is installed in the inner cavity of the disc spring sleeve 5 through the mounting groove 13, the disc spring sleeve 5 can be driven to move upward at this time, thereby achieving the stress effect.
