Description

Technical Field

[0001] This utility model relates to the field of steel leaf spring processing technology, specifically to a steel leaf spring stacking device. Background Technology

[0002] A leaf spring stacking device is used to stack and combine multiple leaf springs together. It can achieve rapid, accurate and stable stacking and combination of leaf springs, thereby improving the production efficiency and quality of leaf springs.

[0003] Chinese patent CN222494192U discloses a stacking device for leaf springs, comprising a worktable with a sliding plate at its top. Symmetrically distributed pressure plates are fixedly mounted on the surface of the sliding plate. A hydraulic rod is fixedly mounted above the worktable, with its output end fixedly connected to the sliding plate. Symmetrically distributed slots are formed on the top of the worktable away from the hydraulic rod. A threaded rod rotatably passes through the inside of each slot, and a locking block is movably engaged within each slot. Both the locking block and the slot are T-shaped. The threaded rod passes through the locking block, and a rotating rod is located at the top of the locking block. This application allows adjustment of the distance between the support block and the pressure plate, as well as the distance of the rotating rod, enabling adjustment of the curvature of the leaf spring's center and sides, facilitating pressing by operators as needed.

[0004] The above-mentioned device has the effect of adjusting the distance between the support block, the pressure plate and the rotating rod. However, when stacking steel plates, the steel plates need to be moved. The steel plates themselves are heavy, resulting in low stacking efficiency and the possibility of the steel plates pinching the hands. At the same time, when using bolts to reinforce different steel plates, there is also the problem of insufficient operating space. Therefore, it is necessary to provide a stacking device for steel plate springs. Utility Model Content

[0005] The purpose of this utility model is to provide a stacking device for leaf springs, so as to solve the problems of existing devices, which are time-consuming and laborious in stacking leaf springs, have the risk of being pinched by the steel plates, and have limited operating space, thus affecting the stacking efficiency of leaf springs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stacking device for steel leaf springs, comprising a workbench, a hydraulic cylinder fixedly mounted on one side of the workbench, and a feeding mechanism provided on the workbench; the feeding mechanism includes a connecting frame, the connecting frame being fixedly mounted on the output end of the hydraulic cylinder, and a first slide block being fixedly mounted on the upper part of the connecting frame, a first slide rod being slidably mounted inside the first slide block, a first spring being fixedly mounted between the first slide rod and the first slide block, a second slide block being fixedly mounted on the upper part of the workbench, a second slide rod being slidably mounted inside the second slide block, a second spring being fixedly mounted between the second slide rod and the second slide block, and several rollers being rotatably mounted side-by-side on the upper part of the workbench.

[0007] Preferably, the first slide bar and the second slide bar are located on the same horizontal line, and the length of the second slide bar is greater than the length of the first slide bar.

[0008] Preferably, two long, strip-shaped slots are arranged side by side in the middle of the workbench, and the connecting frame is embedded and slidably installed in the long, strip-shaped slots.

[0009] Preferably, a clamping mechanism is provided on one side of the workbench. The clamping mechanism includes a second hydraulic cylinder and two limit seats. The second hydraulic cylinder is fixedly installed on the other side of the workbench. The two limit seats are fixedly installed side by side inside the workbench. A main board is fixedly installed on the output end of the second hydraulic cylinder. A first rotating rod is fixedly installed on both ends of the main board. A secondary plate is slidably installed on one end of the first rotating rod. A limit groove is opened on the secondary plate, and a second rotating rod is rotatably installed on the secondary plate. A limit rod is fixedly installed on one side of the second rotating rod and through the limit seat. A buffer spring is fixedly installed between the second rotating rod and the limit seat.

[0010] Preferably, the motherboard is embedded and slidably mounted in the long strip groove, and two short strip grooves are arranged side by side on the upper part of the worktable, and the sub-board is adapted to the short strip grooves.

[0011] Preferably, one end of the second slide is flush with the motherboard, and the first rotating rod is embedded and slidably mounted inside the limiting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This stacking device for leaf springs uses rollers to transport the steel plate to the center of the worktable, where the first slide rod is embedded in a pre-drilled hole in the center of the steel plate. By controlling the first hydraulic cylinder, the steel plate is moved forward so that the first slide rod contacts the second slide rod and the steel plate is continuously pushed forward. When the first hydraulic cylinder is controlled to reset the first slide rod, the steel plate will be nested on the second slide rod. Different steel plates are nested on the second slide rod in sequence, which can reduce the input of manpower and ensure that fingers are not pinched by the steel plates.

[0014] 2) In this stacking device for steel leaf springs, after different steel plates are stacked on the second slide bar, the second hydraulic cylinder is further controlled to move the main plate forward. During the movement of the main plate, the auxiliary plate will rotate and cooperate with the main plate to clamp the steel plate, so that the steel plate moves forward and gets away from the second slide bar, thereby increasing the operating space for bolt fixing of the steel plate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Combination Figures 1-4 A stacking device for leaf springs includes a workbench 1, a hydraulic cylinder 2 fixedly mounted on one side of the workbench 1, and a feeding mechanism 3 provided on the workbench 1. The feeding mechanism 3 includes a connecting frame 301, which is fixedly mounted on the output end of the hydraulic cylinder 2. A first slide block 302 is fixedly mounted on the upper part of the connecting frame 301. A first slide rod 303 is slidably mounted inside the first slide block 302. A first spring 304 is fixedly mounted between the first slide rod 303 and the first slide block 302. A second slide block 305 is fixedly mounted on the upper part of the workbench 1. A second slide rod 306 is slidably mounted inside the second slide block 305. A second spring 307 is fixedly mounted between the second slide rod 306 and the second slide block 305. Several rollers 308 are rotatably mounted side by side on the upper part of the workbench 1.

[0023] See Figure 2 and Figure 3 Furthermore, it is found that the first slide bar 303 and the second slide bar 306 are located on the same horizontal line, and the length of the second slide bar 306 is greater than the length of the first slide bar 303. Two long strip slots are opened side by side in the middle of the worktable 1, and the connecting frame 301 is embedded and slidably installed in the long strip slot.

[0024] Specifically, the steel plate is conveyed to the middle of the workbench 1 by the roller 308, and the first slide rod 303 is further embedded in the reserved hole in the middle of the steel plate. The steel plate is moved forward by controlling the first hydraulic cylinder 2 so that the first slide rod 303 contacts the second slide rod 306 and the steel plate is continuously pushed forward. When the first hydraulic cylinder 2 is controlled to reset the first slide rod 303, the steel plate will be nested on the second slide rod 306. The first spring 304 and the second spring 307 play a buffering role to ensure that the first slide rod 303 and the second slide rod 306 remain in contact during the transfer of the steel plate. Benefiting from the fact that the length of the second slide rod 306 is greater than the length of the first slide rod 303, it is ensured that the steel plate finally stays on the second slide rod 306. Different steel plates are nested on the second slide rod 306 in sequence, which can reduce the input of manpower and ensure that fingers are not pinched by the steel plates.

[0025] Example 2

[0026] Combination Figure 1 and Figure 4A clamping mechanism 4 is provided on one side of the workbench 1. The clamping mechanism 4 includes a second hydraulic cylinder 401 and two limit seats 402. The second hydraulic cylinder 401 is fixedly installed on the other side of the workbench 1. The two limit seats 402 are fixedly installed side by side inside the workbench 1. A main board 403 is fixedly installed on the output end of the second hydraulic cylinder 401. A first rotating rod 404 is fixedly installed on both ends of the main board 403. A secondary plate 405 is slidably installed on one end of the first rotating rod 404. A limit groove 406 is opened on the secondary plate 405, and a second rotating rod 407 is rotatably installed on the secondary plate 405. A limit rod 408 is fixedly installed on one side of the second rotating rod 407 and through the limit seat 402. A buffer spring 409 is fixedly installed between the second rotating rod 407 and the limit seat 402.

[0027] See Figure 4 Furthermore, based on Embodiment 1, the motherboard 403 is embedded and slidably installed in the long strip groove, two short strip grooves are opened side by side on the upper part of the worktable 1, and the sub-plate 405 is adapted to the short strip groove, one end of the second slide block 305 is flush with the motherboard 403, and the first rotating rod 404 is embedded and slidably installed inside the limiting groove 406.

[0028] Specifically, after different steel plates are stacked on the second slide bar 306, the second hydraulic cylinder 401 is further controlled to move the main plate 403 forward. During the movement of the main plate 403, the first rotating rod 404 will move forward synchronously, thereby causing the secondary plate 405 to rotate around the second rotating rod 407 and move forward together with the second rotating rod 407 under the action of the limit rod 408. The main plate 403 and the secondary plate 405 will clamp the steel plate and cause the steel plate to disengage from the second slide bar 306, thereby increasing the operating space for bolt fixing of the steel plate.

[0029] In actual operation, the steel plate is conveyed to the middle of the workbench 1 by the roller 308, and the first slide rod 303 is further embedded in the reserved hole in the middle of the steel plate. The steel plate is moved forward by controlling the first hydraulic cylinder 2 so that the first slide rod 303 contacts the second slide rod 306 and the steel plate is continuously pushed forward. When the first slide rod 303 is reset by controlling the first hydraulic cylinder 2, the steel plate will be nested on the second slide rod 306. The first spring 304 and the second spring 307 play a buffering role to ensure that the first slide rod 303 and the second slide rod 306 remain in contact during the transfer of the steel plate. Benefiting from the fact that the length of the second slide rod 306 is greater than the length of the first slide rod 303, it is ensured that the steel plate finally stops on the second slide rod 306. Different steel plates are nested on the second slide rod 306 in sequence, which can reduce the input of manpower and ensure that fingers are not pinched by the steel plates.

[0030] After the different steel plates are stacked on the second slide bar 306, the second hydraulic cylinder 401 is further controlled to move the main plate 403 forward. During the movement of the main plate 403, the first rotating rod 404 will move forward synchronously, thereby causing the secondary plate 405 to rotate around the second rotating rod 407 and move forward together with the second rotating rod 407 under the action of the limit rod 408. The main plate 403 and the secondary plate 405 will clamp the steel plate and cause the steel plate to disengage from the second slide bar 306, thereby increasing the operating space for bolt fixing of the steel plate.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
