Description

Technical Field

[0001] The invention belongs to the technical field of disc spring assembly, and in particular relates to a disc spring combination error-proof tooling. Background Art

[0002] Disc springs, also known as disc springs, are conical annular discs that bear axial loads. Unlike traditional springs, disc springs have a larger deformation energy per unit volume and have good shock absorption capabilities. Especially when stacked, due to the surface friction resistance, the effect of absorbing shock and dissipating energy is more significant. In addition, by changing the number of discs or the combination of discs, different load-bearing capacities and characteristic curves can be obtained.

[0003] In the prior art, disc spring assemblies are mostly assembled manually, and there are few dedicated installation tools. For example, the disc spring gasket assembly error prevention device disclosed in the patent document with publication number CN112109044A solves the problem that disc springs are easily installed upside down, but cannot solve the problem of whether the disc spring assembly has missed installation. Summary of the invention

[0004] Based on the above-mentioned shortcomings and deficiencies in the prior art, the object of the present invention is to provide a disc spring combination error-proof tooling.

[0005] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions:

[0007] As a preferred solution, the push rod is provided with a sensing sheet, and a sensing switch is provided corresponding to the sensing sheet; when the push rod slides over all the corresponding positioning members, the sensing sheet triggers the sensing switch.

[0008] As a preferred solution, a reset spring is provided in the slideway of the disc spring seat for resetting the push rod that slides over the locking member.

[0009] As a preferred solution, there are multiple disc spring seats, which are distributed side by side; the push rods are arranged in one-to-one correspondence with the disc spring seats, and the push rods are parallel to each other.

[0011] As a preferred embodiment, the movable pin includes a main body limiting portion and a limit releasing portion extending therefrom. A portion of the main body limiting portion extends into the slideway of the disc spring seat to limit the sliding stroke of the push rod on the slideway; the limit releasing portion extends into the disc spring anti-error groove of the disc spring seat to realize the limit releasing through the linkage of the disc spring installed in the disc spring anti-error groove.

[0012] As a preferred solution, the main body limiting portion and the limiting release portion of the movable pin are both cylindrical structures and are coaxial, and the diameter of the main body limiting portion is greater than the diameter of the limiting release portion.

The bottom plate, the two side panels and the base are fixedly installed to each other to form a cavity structure; the connecting frame and the movable guide structure are located within the cavity structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The disc spring assembly error-proof tooling of the present invention can prevent the disc spring assembly from being reversed and prevent the disc springs from being missed, thereby improving the efficiency of the disc spring assembly installation and the accuracy of the disc spring quantity.

[0026] In order to more clearly illustrate the embodiments of the present invention, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For those of ordinary skill in the art, other accompanying drawings and other implementation methods can be obtained based on these accompanying drawings without creative work.

[0027] Embodiment 1:

[0028] like Figure 1-8 As shown, the disc spring combination anti-error tooling of this embodiment includes a bottom plate 1, two side plates 2, a base 3, four disc spring seats 4, four push rods 5, a return spring 6, a sensor sheet 7, a sensor switch 8, a connecting frame 9 and a cylinder 10.

[0029] Two side panels 2 are fixedly mounted on both sides of the bottom plate 1, and a base 3 is fixedly mounted above the two side panels 2, so that the bottom plate, the two side panels and the base form a cavity structure A to provide installation space for other components.

[0030] The four disc spring seats 4 of this embodiment are installed side by side above the base 3. Each disc spring seat has a slideway extending along its length direction. The push rod 5 is slidably matched with the slideway of the disc spring seat, and each push rod is parallel to each other. Specifically, the slideway includes a main body section a and a clamping section b distributed in sequence along the plugging direction of the push rod. The inner diameter of the main body section a is larger than the inner diameter of the clamping section b. Accordingly, the push rod 5 has a circumferentially distributed flange 50. The outer diameter of the flange 50 matches the inner diameter of the main body section a of the slideway. A reset spring 6 is arranged between the flange 50 and the diameter-changing position of the main body section and the clamping section of the slideway for resetting the push rod. The diameter of a section of the push rod located on the right side of the flange 50 matches the inner diameter of the clamping section b of the slideway, and the diameter of a section of the push rod located on the left side of the flange 50 matches the caliber of the plugging interface of the slideway.

[0031] In addition, corresponding to the position of the blocking section b of the slideway, the disc spring seat 4 has three disc spring anti-error grooves 40 distributed along the axial direction of the push rod. The disc spring anti-error grooves 40 are used for the directional placement of the disc spring, that is, the structure of the disc spring anti-error groove is adapted to the positive and negative structure of the disc spring to prevent the disc spring from being installed in reverse. Among them, a blocking piece 11 is correspondingly arranged in each disc spring anti-error groove 40, so that each blocking piece sequentially limits the sliding stroke of the push rod on the slideway; when the disc spring is placed in the disc spring anti-error groove, the disc spring links the corresponding blocking piece to move to release the limit on the push rod, so that the push rod can continue to slide in the slideway. With such a design, only when all disc spring anti-error grooves are installed with disc springs, the push rod can slide to cross all the blocking pieces to reach the target position, and the above-mentioned reset spring can reset the push rod that has reached the target position; as long as there is a disc spring anti-error groove without a disc spring installed, the push rod cannot get the target position.

[0032] Specifically, the base 3 has a mounting hole 30, and the mounting hole 30 corresponds to the locking member 11 one by one. The locking member 11 includes an elastic member 11-1 and a movable pin 11-2 connected thereto. The elastic member 11-1 is installed in the mounting hole 30 of the base; when the elastic member 11-1 is in a free state, the movable pin 11-2 extends into the disc spring anti-mistake groove 40 and the slideway of the disc spring seat. Among them, the movable pin 11-2 includes a main body limiting portion 11-a connected to the elastic member 11 and a limiting release portion 11-b extending therefrom. The main body limiting portion and the limiting release portion of the movable pin are both cylindrical structures and are coaxial. The diameter of the main body limiting portion is larger than the diameter of the limiting release portion; as shown in FIG. Figure 6 As shown, a portion of the main body limiting portion 11-a extends into the slideway of the disc spring seat to limit the sliding stroke of the push rod on the slideway; the limit release portion 11-b extends into the disc spring anti-error groove 40 of the disc spring seat to achieve limit release through the linkage of the disc spring installed in the disc spring anti-error groove.

[0033] In this embodiment, the left end of each push rod 5 is provided with a sensing piece 7, which passes through the slide groove 31 of the base and can reciprocate along the length direction of the slide groove 31. Figure 3 As shown; a sensing switch 8 is provided corresponding to the sensing sheet 7; all the sensing switches are installed on the bottom plate 1 and are located within the cavity structure A, so as to realize the built-in installation of the sensing switch. When the push rod slides to pass all the corresponding positioning parts and reaches the target position, the sensing sheet 7 triggers the corresponding sensing switch 8, and the sensing switch 8 outputs a corresponding signal to indicate that the number of the disc spring combination is accurate.

[0034] All push rods 5 of this embodiment are connected to the connecting frame 9 to form an integrated linkage structure; the connecting frame 9 is located in the cavity structure A to achieve built-in installation; the connecting frame 9 is connected to the cylinder 10 by driving, and the cylinder 10 is installed on the bottom plate 1 and the base 3 through the cylinder fixing seat to achieve synchronous sliding of the push rods, and can achieve error-proof assembly of multiple sets of disc spring combinations at one time. In addition, a movable guide structure is provided between the connecting frame 9 and the base 3 of this embodiment, and the movable guide structure is located in the cavity structure to achieve built-in installation; the movable guide structure includes a guide groove 90 opened on the connecting frame 9 and a positioning pin sleeve 12 installed on the base 3, and the width of the guide groove matches the outer diameter of the positioning pin sleeve, which ultimately improves the stability of the sliding of the push rod.

[0041] The cylinder can also replace the existing commonly used linear drive mechanism, such as the combination of a motor and a screw slide;

[0042] For other structures, please refer to Example 1.

[0043] Embodiment 4:

[0044] The disc spring combination error-proofing tool of this embodiment is different from that of embodiment 1 in that:
