Description

Technical Field

[0001] This invention relates to the field of spring manufacturing, and more specifically to a compression spring inner and outer diameter sorting device. Background Technology

[0002] With the development of automation, many large, high-end manufacturers have adopted automated assembly for small parts such as compression springs. This places higher demands on spring dimensions, especially the inner and outer diameters involved in assembly. If these dimensions are out of tolerance, assembly may fail or disrupt the normal operation of the production line. This is particularly true in the automotive industry, where production line shutdowns can result in significant economic losses. This invention aims to solve the problem of efficiently and cost-effectively sorting the inner and outer diameters of compression springs. Summary of the Invention

[0003] The purpose of this invention is to provide a device for sorting the inner and outer diameters of compression springs.

[0004] The present invention achieves the above-mentioned objective through the following technical solution: a compression spring inner and outer diameter sorting device, including an inner and outer diameter sorting mechanism, a vibrating hopper for conveying springs to the inner and outer diameter sorting mechanism, and a spring feeder for feeding the vibrating hopper. The vibrating hopper has five material pipes at its end, through which springs are conveyed to five sorting components of the inner and outer diameter sorting mechanism. The inner and outer diameter sorting mechanism has five sorting components arranged horizontally side-by-side at equal intervals. A display and operation panel is located on the top of the inner and outer diameter sorting mechanism. The inner and outer diameter sorting mechanism has a platform, and a lower fixed plate is located below the platform. All five sorting components are installed between the platform and the lower fixed plate. Below the lower fixed plate is a discharge bin, and the lower fixed plate has five discharge holes, each located directly below each sorting component.

[0005] Furthermore, the sorting assembly includes an outer diameter sorting mounting plate, on which an outer diameter sorting sleeve is mounted, and the outer diameter sorting sleeve has an outer diameter sorting hole at its center.

[0006] Furthermore, the sorting component includes a discharge mandrel located directly below the outer diameter sorting hole. The top of the discharge mandrel is used to insert into the inner diameter of the spring. After being conveyed, the spring first enters the outer diameter sorting hole. If the outer diameter of the spring exceeds the standard value, it cannot enter. Only if the outer diameter of the spring meets the standard value can it enter. In this way, the sorting of the outer diameter of the spring is completed first.

[0007] Furthermore, a spring sensing sensor mounting plate is provided below the outer diameter sorting mounting plate, and a horizontally placed spring sensing sensor is provided on the inner diameter sensor mounting plate.

[0008] Furthermore, the spring sensing sensor is located on the side of the lower part of the top of the blanking mandrel. After the spring is sorted by outer diameter, it falls from the outer diameter sorting hole and fits on the top of the blanking mandrel. If the outer diameter of the spring is smaller than the standard value, it cannot fit on the blanking mandrel, and the spring sensing sensor located on the side of the lower part of the top of the blanking mandrel cannot sense the spring, which means that the inner diameter of the spring is unqualified. Conversely, if the outer diameter of the spring meets the standard value, the spring sensing sensor can sense the spring, the inner diameter of the spring is qualified, and then the spring enters the blanking process.

[0009] Compared with the prior art, the beneficial effects of the compression spring inner and outer diameter sorting device of the present invention are: it can be equipped with five sets of the above-mentioned workstations at the same time to sort five sets of springs simultaneously, which greatly improves the sorting efficiency. Moreover, the device has high compatibility and physical sorting. It can be used to sort different products by simply changing different blanking mandrels and outer diameter sorting sleeves. It is highly efficient, low-cost, simple in structure, easy to maintain, and less prone to errors. Attached Figure Description

[0014] Please see Figures 1 to 4 A compression spring inner and outer diameter sorting device includes an inner and outer diameter sorting mechanism 1, a vibrating hopper 3 for conveying springs to the inner and outer diameter sorting mechanism 1, and a spring feeder 5 for feeding the vibrating hopper 3. The vibrating hopper 3 is provided with five material pipes 4 at its end, and the springs are conveyed to the five sorting components 11 of the inner and outer diameter sorting mechanism 1 through five flexible hoses (not shown).

[0015] The inner and outer diameter sorting mechanism 1 has five sorting components 11, which are arranged horizontally side by side at equal intervals. The top of the inner and outer diameter sorting mechanism 1 has a display and operation panel 2. The inner and outer diameter sorting mechanism 1 has a platform 12, and a lower fixing plate 13 is provided below the platform 12. All five sorting components 11 are installed between the platform 12 and the lower fixing plate 13. Below the lower fixing plate 13 is a material discharge bin 14. The lower fixing plate 13 has five material discharge holes 13, each of which is located directly below each sorting component 11.

[0016] The sorting assembly 11 includes an outer diameter sorting mounting plate 1101, on which an outer diameter sorting sleeve 1102 is mounted. The outer diameter sorting sleeve 1102 has an outer diameter sorting hole 1103 at its center. After being conveyed, the spring first enters the outer diameter sorting hole 1103. If the outer diameter of the spring exceeds the standard value, it cannot enter. Only when the outer diameter of the spring meets the standard value can it enter. In this way, the sorting of the outer diameter of the spring is completed first.

[0017] The outer diameter sorting mounting plate 1101 is equipped with a spring release mechanism 1112. The spring release mechanism 1112 includes a horizontally positioned release cylinder 1113. The release cylinder 1113 has an upper stop block 1114 and a lower stop block 1115. The upper stop block 1114 is inserted into a through hole 1116 in the side wall of the diameter sorting sleeve 1102, and the lower stop block 1115 is located on the lower side of the bottom of the diameter sorting sleeve 1102. The function of the spring release mechanism 1112 is to change the continuous spring input into a step-by-step manner, avoiding spring blockage. Through rhythmic release, springs that have passed the outer diameter sorting are placed into the next inner diameter sorting stage. Specifically, the release cylinder 1113 drives the upper stop block 1114 and the lower stop block 1115 to move laterally, thereby blocking or releasing the springs.

[0018] The sorting assembly 11 includes a discharge mandrel 1109, which is located directly below the outer diameter sorting hole 1103. The top of the discharge mandrel 1109 is used to insert the inner diameter of a spring. A spring sensing sensor mounting plate 1110 is provided below the outer diameter sorting mounting plate 1101. The inner diameter sensor mounting plate 1110 is provided with a horizontally placed spring sensing sensor 1111, which is located on the side of the lower part of the top of the discharge mandrel 1109. The spring is connected to the outer diameter sorting hole 1103. After diameter sorting, the spring falls through the outer diameter sorting hole 1103 and is fitted onto the top of the blanking mandrel 1109. If the outer diameter of the spring is smaller than the standard value, it cannot be fitted onto the blanking mandrel 1109. The spring sensing sensor 1111 located on the side of the lower part of the top of the blanking mandrel 1109 will not be able to sense the spring, indicating that the inner diameter of the spring is unqualified. Conversely, if the outer diameter of the spring meets the standard value, the spring sensing sensor 1111 can sense the spring, the inner diameter of the spring is qualified, and then the spring enters the blanking process.

[0019] The sorting assembly 11 is equipped with a cylinder gripper mounting plate 1104, which has four cylinder grippers from top to bottom: a first cylinder gripper 1105, a second cylinder gripper 1106, a third cylinder gripper 1107, and a fourth cylinder gripper 1108. These four cylinder grippers are used to hold the discharge mandrel 1109 to prevent it from falling. When the spring has passed the inner diameter sorting and needs to be discharged, it is lowered step by step through an intermittent opening mechanism, eventually falling into the discharge bin 14. The specific process is as follows: At the start of operation, the first and third cylinder grippers tighten, while the second and fourth cylinder grippers loosen. A spring with a suitable inner diameter falls onto the first cylinder gripper. Upon receiving a signal from the spring sensor indicating that the spring has fallen onto the first cylinder gripper, the program controls the second and fourth cylinder grippers to tighten again, and the first and third cylinder grippers to loosen. The spring falls onto the second cylinder gripper. Once there is no spring on the first cylinder gripper, the spring sensor receives a signal indicating that there is no spring. The program then controls the first and third cylinder grippers to tighten again, followed by the second and fourth cylinder grippers to loosen, allowing the spring to fall naturally. This reciprocating motion suspends the material core rod, and the springs pass smoothly through the third and fourth cylinder grippers one by one, finally falling into the material hopper.

[0020] The blanking mandrel and outer diameter sorting sleeve can be replaced according to different models and sizes of springs.

[0021] This invention can be equipped with five sets of the above-mentioned workstations simultaneously, performing sorting with five sets of springs at the same time, greatly improving sorting efficiency. The equipment is highly compatible, using physical sorting; simply changing the different discharge mandrels and outer diameter sorting sleeves allows for the sorting of different products. It is highly efficient, low-cost, simple in structure, easy to maintain, and less prone to errors. Furthermore, it can be equipped with a vibrating hopper for automatic feeding, allowing one person to manage multiple machines simultaneously, significantly improving the sorting efficiency of a single worker.

The lower fixed plate has five discharge holes, each located directly below each sorting component. Each sorting component includes an outer diameter sorting mounting plate with an outer diameter sorting sleeve mounted on it. The outer diameter sorting sleeve has an outer diameter sorting hole at its center. The sorting component also includes a discharge mandrel located directly below the outer diameter sorting hole. The top of the discharge mandrel is used to insert into the inner diameter of a spring. After being conveyed, the spring first enters the outer diameter sorting hole.

In this way, the outer diameter of the spring is sorted first. Below the mounting plate is a spring sensor mounting plate, and the inner diameter sensor mounting plate has a horizontally positioned spring sensor. The spring sensor is located on the side of the lower part of the top of the blanking mandrel. After the spring is sorted by outer diameter, it falls from the outer diameter sorting hole and fits onto the top of the blanking mandrel. If the outer diameter of the spring is smaller than the standard value, it cannot fit onto the blanking mandrel, and the spring sensor on the side of the lower part of the top of the blanking mandrel will not detect the spring, indicating that the inner diameter of the spring is unqualified. Conversely, if the outer diameter of the spring meets the standard value, the spring sensor will be able to detect the spring, and the inner diameter of the spring is qualified. The spring enters the unloading stage; the outer diameter sorting mounting plate is equipped with a spring release mechanism, which includes a horizontally placed release cylinder. The release cylinder has an upper stop and a lower stop. The upper stop is inserted into the through hole in the side wall of the outer diameter sorting sleeve, and the lower stop is located on the bottom side of the outer diameter sorting sleeve. The sorting component is equipped with a cylinder gripper mounting plate. The cylinder gripper mounting plate has four cylinder grippers from top to bottom. The four cylinder grippers are used to grip the unloading mandrel to prevent it from falling. When the spring needs to be unloaded after passing the inner diameter sorting, it is opened at intervals to drop the spring step by step until it finally falls into the unloading bin.
