Description

Technical Field

[0001] The utility model relates to the field of spring detection, in particular to a tower spring feeding component and a tower spring detection system. Background Art

[0002] The tower spring is a shock-absorbing spring, whose main features are small size, large load and variable stiffness. These features make it widely used in small space, large load occasions and shock-absorbing devices. The design and production of the tower spring are relatively complex, and multiple parameters need to be considered, such as free height, deformation, outer diameter, inner diameter, load, wire diameter, working circle, total circle, etc. The shape of this tower spring is mainly conical, with some gaps between the circles. When subjected to external loads, it will shrink and deform to store deformation energy.

[0003] Tower springs have various functions, including controlling mechanical movement, absorbing vibration and impact energy, storing and outputting energy as power, and being used as force measuring elements. The ratio of the load to the deformation of a spring is called the spring stiffness. The greater the stiffness, the harder the spring. Springs are elastic elements widely used in the mechanical and electronic industries. They can produce large elastic deformations when loaded, converting mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the spring disappears and returns to its original state, converting deformation energy into mechanical work or kinetic energy.

[0004] When tower springs are produced and shipped out of the factory, they need to be inspected and load sorted. During this process, batches of tower springs need to be sent to testing equipment such as circulating presses in sequence. During the loading stage, due to the structural characteristics of the tower spring with one end thick and the other end thin, the loading device usually adopts a vibrating loader, and its last section of the conveying track adopts a flat plate design. The thick end coil of the tower spring is hung on the flat plate. It can be seen that the tower spring has the thick end on top and the thin end on the bottom during the loading stage, which is opposite to the usual use condition of the tower spring with the thick end on the bottom and the thin end on the top. Summary of the invention

[0005] The utility model provides a tower spring feeding component to solve the problem that the position of the tower spring in the feeding stage is opposite to the actual use condition when the tower spring is tested.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is a tower spring feeding assembly, including a containing assembly and a switch assembly, wherein the containing assembly is connected to a rotating mechanism, the rotating end of the rotating mechanism is fixedly connected to the containing assembly, and a containing cavity with at least one end open is provided in the containing assembly, and the depth direction of the containing cavity is perpendicular to the rotating axis of the rotating mechanism; the switch assembly can block the open end of the containing assembly, and open at a first circumferential position and a second circumferential position centered on the rotating axis of the rotating mechanism. The feeding assembly is installed on the conveying line of the tower spring. After the tower spring falls into the containing cavity, the containing assembly flips the tower spring up and down by rotating itself, falls out from the opening of the second circumferential position and enters the subsequent testing process, so that the tower spring test is closer to the actual use and installation state, and the detection rationality is improved.

[0007] Preferably, the switch assembly includes a ring plate, a first through slot is provided at a first circumferential position on the ring plate, a second through slot is provided at a second circumferential position on the ring plate, the rotation axis of the rotating mechanism is located at the center of the ring plate, the accommodating assembly is located in the ring of the ring plate, and the rotation path of the open end of the accommodating cavity passes through the first through slot and the second through slot. By setting the ring plate, the opening of the accommodating cavity is blocked during the rotation of the accommodating assembly, and the tower spring falls out when the opening of the accommodating cavity rotates to the second through slot, and the tower spring's own gravity is used to cleverly achieve material loading.

[0008] Preferably, a sealing plate is further provided in the first through slot and / or the second through slot, the sealing plate is connected to a telescopic mechanism, and the telescopic axis of the telescopic mechanism is parallel to the rotation axis of the rotating mechanism. An openable sealing plate is provided to close the through slot to avoid mechanical jamming caused by the tower spring being stuck in the through slot when the rotation is not in place.

[0009] Preferably, the rotating mechanism adopts a rotating cylinder.

[0010] Preferably, the telescopic mechanism adopts a telescopic cylinder.

[0011] Preferably, the first circumferential position is spaced 180 degrees from the second circumferential position.

[0012] Preferably, in the accommodating assembly, a plurality of accommodating cavities are provided, and the angular intervals between the plurality of accommodating cavities are adapted to the angular intervals between the first circumferential positions and the second circumferential positions.

[0013] On the other hand, the utility model also provides a tower spring detection system, including a feeding device and a detection device, the above-mentioned tower spring feeding assembly is arranged between the feeding device and the detection device, the discharge end of the feeding device is located above the first circumferential position of the switch assembly, and the feeding end of the detection device is located below the second circumferential position of the switch assembly.

[0014] Preferably, the feeding device adopts a vibrating feeding tray.

[0015] Preferably, a guide tube is provided between the discharge end of the feeding device and the first circumferential position of the switch assembly.

[0016] It can be seen from the above technical scheme that the advantages of the utility model are that the scheme designs a tower spring feeding assembly, which can flip the tower spring up and down during the tower spring feeding process, so that the thick end of the tower spring is at the bottom and the thin end is at the top to enter the testing machine, so that subsequent tests are closer to the actual use state of the tower spring, and the accuracy of the test is improved; the structural design of the scheme is reasonable and ingenious, the action is fast and the efficiency is high; furthermore, the tower spring detection system provided by the utility model has higher rationality of results.
