Description

Technical Field

[0001] This utility model relates to the field of automotive leaf spring processing technology, specifically to an automotive leaf spring stacking and feeding device. Background Technology

[0002] Automotive leaf springs are often used in heavy-duty trucks and are usually composed of multiple steel plates of different lengths with curvature stacked together. As the core elastic element of the suspension system, the automotive leaf spring bears the static load and dynamic impact load of the vehicle and prevents the frame from directly rigidly contacting the axle. The manufacturing process of automotive leaf springs requires the cut leaf springs to undergo rolling processing. After heating the blank, it is rolled into a conical or parabolic shape through a long conical rolling mill. This includes steps such as stamping the center hole, trimming the edges, and bending. Traditionally, the material is manually transported to a conveyor belt and then sent to the rolling mill and other subsequent processing equipment.

[0003] Analysis of existing technologies revealed that traditional leaf spring raw material supply requires manual handling, but the raw material plates are heavy and consume a lot of workers' physical strength. Moreover, only one raw material can be loaded at a time, requiring workers to frequently move the raw material plate back and forth, resulting in low work efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes an automotive leaf spring stacking and feeding device to solve the technical problems mentioned in the background art, which require manual handling of traditional leaf spring raw material plates. However, the raw material plates are heavy and consume a lot of workers' physical strength. Moreover, only one plate can be fed at a time, requiring workers to frequently move the raw material plates back and forth, resulting in low work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive leaf spring stacking feeding device, comprising: The base plate is fixedly mounted with a frame to accommodate stacked leaf spring raw material plates; The pusher plate is slidably disposed at the bottom of the frame via a feeding mechanism, and the feeding mechanism drives the pusher plate to circulate along a square trajectory. A drive assembly, disposed on the base plate, drives the feeding mechanism to move; and A conveyor belt is fixedly connected to the base plate and located on one side of the frame to receive the leaf spring raw material plate pushed out by the pusher plate.

[0006] Furthermore, the feeding mechanism includes: Guide rods are located at the bottom of the frame; A slider, one end of which is slidably mounted on the guide rod, and the other end of which is slidably connected to the pusher plate; and The swing arm is rotatably mounted on the pusher plate.

[0007] Furthermore, the driving component includes: The support is fixedly installed on the base plate; A drive rod is rotatably mounted on the support, one end of the drive rod is slidably connected to the swing arm, and the other end of the drive rod is provided with a rotating handle; and A spring is inserted through the swing arm, and its two ends abut against the swing arm and the drive rod, respectively.

[0008] Furthermore, the pusher plate is also provided with a first limiting block.

[0009] Furthermore, a second limiting block is also installed at one end of the swing arm.

[0010] Furthermore, a first clearance groove is provided at the bottom of the frame.

[0011] Furthermore, a second clearance groove is also provided on the base plate.

[0012] Furthermore, a discharge port is also provided at the bottom of the frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The frame of this device can accommodate stacked leaf spring raw material plates. The plates are stacked once and output multiple times, thereby reducing the number of times workers have to move the raw material plates. When feeding is needed, the worker only needs to use the drive component to drive the feeding mechanism to push the pusher plate to move cyclically along the square track, achieving the effect of reciprocating pushing and retracting. This can complete the feeding of leaf spring raw material plates in a long time, saving workers' physical strength and time for back-and-forth carrying, and improving work efficiency.

[0014] 2. The feeding mechanism of this device utilizes the linkage principle and operates in three stages. The first stage completes the lifting and locking of the push plate, the second stage completes the lateral movement of the push plate to push the material, and finally the push plate descends, detaches from the raw material plate, and retracts to the origin to form a cycle. The entire process only requires the worker to turn the rotating handle. This device has a compact structure, is easy to operate, avoids contact between the worker and the raw material plate, and reduces the risk of factory accidents. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0019] Example: like Figure 1 As shown, this utility model provides an automotive leaf spring stacking and feeding device, including a base plate 101, a frame 102, a drive assembly, and a conveyor belt 401 mounted on the base plate 101. A pusher plate 201 is slidably disposed at the bottom of the frame 102 and is slidably connected to the feeding mechanism. Under the control of the feeding mechanism, the pusher plate 201 can move cyclically along a square trajectory to achieve a cyclic action of pushing and retracting. The conveyor belt 401 is located on one side of the frame 102 to receive the leaf spring raw material plates pushed out by the pusher plate 201. The frame 102 of this device can accommodate stacked leaf spring raw material plates, thereby reducing the number of times the raw material plates are handled. Workers only need to use the drive assembly to drive the feeding mechanism to push the pusher plate 201 back and forth to push and retract, which can complete the feeding of leaf spring raw material plates for a long time, saving workers' physical strength and the time for back and forth handling, and improving work efficiency.

[0020] like Figure 2The feeding mechanism shown includes: a guide rod 202, a slider 203, and a swing arm 204. The driving assembly includes: a support 301, a drive rod 302, a rotating handle 303, and a spring 304. A guide rod 202 is provided at the bottom of the frame 102. The guide rod 202 is slidably connected to the slider 203. One end of the slider 203 is slidably connected to the push plate 201. The swing arm 204 is rotatably connected to the push plate 201. The support 301 is fixedly installed on the base plate 101. The drive rod 302 is rotatably arranged on the support 301. One end of the drive rod 302 is slidably connected to the swing arm 204, and the other end of the drive rod 302 is provided with a rotating handle 303. The rotating handle 303 allows the operator to easily turn the drive rod 302 to drive the swing arm 204 to rotate. The rotation of the swing arm 204 causes the push plate 201 to rise and fall.

[0021] When the pusher plate 201 contacts the leaf spring, the upward movement stops (the first limit block 205 installed on the pusher plate 201 serves as a safety measure in case there is no leaf spring to push against). At this time, the swing arm 204 continues to rotate. The swing arm 204 can only compress the spring 304 to shorten the swing radius to maintain the rotational movement, while the pusher plate 201 moves laterally under the drive of the swing arm 204. When the lateral movement of the pusher plate 201 exceeds the center of rotation of the swing arm 204, the swing arm 204 no longer compresses the spring 304 but instead releases the spring 304 and gradually increases the swing radius (the second limit block 206 installed at one end of the swing arm 204 limits the maximum swing radius of the swing arm 204) until the pusher plate 201 completely pushes out the leaf spring, and the swing arm 204 continues to rotate. 4. The pusher plate 201 descends and stops descending at the upper surface of the slider 203. The subsequent retraction and extension actions of the pusher plate 201 are exactly the same and will not be described in detail here. The conveyor belt 401 installed on one side of the frame 102 will receive the leaf spring pushed out by the pusher plate 201 and transport it to the next processing equipment. The feeding mechanism of this device uses the linkage principle and operates in three stages. The first stage completes the lifting and locking of the pusher plate 201. The second stage completes the lateral movement of the pusher plate 201 to push the material. Finally, the pusher plate 201 descends, disengages from the raw material plate, and retracts to the origin to form a cycle. The entire process only requires the worker to turn the rotating handle 303. This device has a compact structure, is easy to operate, avoids contact between the worker and the raw material plate, and reduces the risk of factory accidents.

[0022] like Figure 2 As shown, a first clearance groove 103 is provided at the bottom of the frame 102 so that the pusher plate 201 can smoothly reach the bottom of the leaf spring raw material plate when it rises. A second clearance groove 104 is provided on the bottom plate 101 so that the swing arm 204 will not interfere with the bottom plate 101 during the swinging process. A discharge port 105 is provided at the bottom of the frame 102 so that the pusher plate 201 can smoothly push the leaf spring raw material plate out of the frame 102.

[0023] The specific usage and beneficial effects of this utility model are as follows: The operator loads the leaf spring raw material plates into the frame 102 in batches, and rotates the rotary handle 303 to drive the swing arm 204 to rotate. The rotation of the swing arm 204 causes the pusher plate 201 to rise and fall. When the pusher plate 201 contacts the leaf spring, the rising action stops. The swing arm 204 continues to rotate, and the swing arm 204 can only compress the spring 304 to shorten the swing radius to maintain the rotation action. Under the action of the swing arm 204, the pusher plate 201 changes to a lateral movement. When the lateral movement of the pusher plate 201 exceeds the center of rotation of the swing arm 204, the swing arm 204 no longer compresses the spring 304, but instead releases the spring 304 and gradually increases the swing radius until the pusher plate 201 completely pushes out the leaf spring. The swing arm 204 continues to rotate, and the pusher plate 201 descends and retracts to the original point to form a cycle. The whole process only requires the worker to turn the rotary handle 303. This device has a compact structure, is simple to operate, avoids contact between the worker and the raw material plates, reduces the risk of factory accidents, saves the worker's physical strength and the time for back-and-forth transportation, and improves work efficiency.
