Description

Technical Field

[0001] This utility model relates to the field of structural reinforcement technology, and in particular to a support mechanism for a bridge shell raw material melting device. Background Technology

[0002] The axle housing is a key component of an automobile axle. Gray cast iron is commonly used in traditional automobile manufacturing because of its good casting performance and low cost. For vehicles with less demanding axle housing performance requirements, such as ordinary light trucks and some buses, gray cast iron axle housings can meet basic usage requirements. In mass production, it allows for effective cost control, and the casting process is mature and production efficiency is high.

[0003] For example, the patent publication number CN111278587A, "A Powder Bed Melting Device", includes a building chamber, a building platform in the building chamber for supporting a powder bed, a layer forming device for forming a powder layer to form a powder bed, a scanner for sweeping an energy beam across the powder bed to melt the powder, and a gas circuit for forming an airflow across the powder bed.

[0004] Bridge shell raw materials are fed at a uniform speed via a conveyor belt, allowing them to enter the melting equipment cavity according to volume control. This enables control over the melting progress of the bridge shell raw materials, resulting in better material properties. However, in existing technologies, different batches or types of bridge shell raw materials may vary in shape, size, and weight distribution. The resistance experienced by the raw materials during feeding varies. When the existing conveyor belt bottom support structure cannot adjust the conveyor belt slope, and when the resistance of the conveyed raw materials differs from the gravitational component provided by the slope, it becomes difficult to control the feeding speed, which can easily affect the material properties. Summary of the Invention

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a support mechanism for a bridge shell raw material melting device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a support mechanism for a bridge shell raw material melting device, comprising a first frame and a second frame, wherein the top ends of both the first and second frames are rotatably connected to hinge seats, the top ends of the hinge seats are fixedly connected to support plates, the support plates overlap the bottom surface of the raw material conveyor belt of the melting device, one end of the second frame is rotatably engaged with a threaded screw, the outer side wall of the threaded screw is threadedly connected to a threaded seat, the two ends of the threaded seat are respectively fixedly connected to the inner side wall of the first frame, and one end of the threaded screw is fixedly connected to a rotating disk.

[0007] Preferably, one end of the second support frame is fixedly connected to a limiting post, and the outer side wall of the limiting post is slidably connected to the inner side wall of the first support frame.

[0008] Preferably, both the first and second uprights are fixedly connected to the bottom end with casters.

[0009] Preferably, the inner walls of both the first and second uprights are fixedly connected to a positioning frame and a support frame, and the inner walls of both uprights are rotatably connected to a rotating shaft.

[0010] Preferably, a base is fixedly connected to the top of the positioning frame, a rocker arm is rotatably connected to the side wall of the support frame, and a spring is fixedly connected between the rocker arm and the base.

[0011] Preferably, a rotating shaft is provided above the rocker arm, a knob is fixedly connected to one end of the rotating shaft, and an involute balance wheel is fixedly connected to the outer side wall of the rotating shaft.

[0012] Preferably, a limiting plate is fixedly connected to the outer wall of the rocker arm, the involute swing wheel overlaps with the limiting plate, and a striking plate is fixedly connected between the two rocker arms.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the rotation of the screw driven by the rotary disc allows for precise control of the distance between the first and second uprights in a simple and efficient manner. This enables flexible and reasonable adjustment of the slope of the support plate, ensuring close contact with the conveyor belt surface. Furthermore, it allows for obtaining more ideal slope conditions according to actual needs, thereby meeting the specific requirements of the bridge shell material during the feeding process and enhancing the adaptability and controllability of the entire feeding process.

[0015] 2. In this utility model, by rotating the knob, a series of components work together. With the cooperation of components such as the involute swing wheel, the limiting plate, the rocking rod, the spring and the striking plate, the raw material deposited and blocked above the conveyor belt can be struck and shaken down, thereby effectively clearing the blocked raw material and ensuring that the feeding process is restored to smoothness.

[0016] 3. In this utility model, the slope difference formed by the different heights of the top of the first and second uprights allows the bridge shell material to move downward spontaneously by utilizing the gravity effect of the slope and smoothly enter the inner cavity of the melting equipment, thus achieving automatic feeding and improving feeding efficiency. The angles of the two support plates can be freely adjusted, which can better fit the surface of the conveyor belt, increase the aligned support area, and ensure effective support for the conveyor belt.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figure 1 - Figure 5 As shown, this utility model provides a support mechanism for a bridge shell raw material melting device, including a first frame 1 and a second frame 2. The top ends of both the first frame 1 and the second frame 2 are rotatably connected to hinge seats 8. The top end of the hinge seats 8 is fixedly connected to a support plate 6. The support plate 6 overlaps the bottom surface of the raw material conveyor belt of the melting device. One end of the second frame 2 is rotatably clamped with a threaded screw 4. The outer side wall of the threaded screw 4 is threadedly connected to a threaded seat 5. The two ends of the threaded seat 5 are respectively fixedly connected to the inner side wall of the first frame 1. One end of the threaded screw 4 is fixedly connected to a rotating disk 9.

[0026] The specific setup and function of this embodiment are described below. The support mechanism is installed below the raw material conveyor belt of the melting equipment. Its two support plates 6 are in direct contact with the conveyor belt. Since the angle of the two support plates 6 can be freely adjusted, the support plates 6 can better fit the surface of the conveyor belt, increasing the aligned support area. The top heights of the first frame 1 and the second frame 2 are different, so the two support plates 6 form a slope difference between the first frame 1 and the second frame 2. The bridge shell raw material is added from one end of the conveyor belt and enters the inner cavity of the melting equipment along the conveyor belt. It utilizes the gravity effect of the slope, causing the bridge shell raw material to move downward spontaneously. A threaded screw 4 is installed between the first support frame 1 and the second support frame 2. The threaded screw 4 is not only rotatably engaged with the second support frame 2, but also threadedly connected to the threaded seat 5. By manually rotating the rotating disk 9 from the outside, the rotating disk 9 drives the threaded screw 4 to rotate, thereby adjusting the distance between the first support frame 1 and the second support frame 2. Since the slope formed by the two support plates 6 is related not only to the height difference between the first support frame 1 and the second support frame 2, but also to the distance between the first support frame 1 and the second support frame 2, the slope of the support plate 6 can be reasonably adjusted by adjusting the threaded screw 4, so that it fits the surface of the conveyor belt, allowing the conveyor belt to have a higher slope for the bridge shell material to be fed.

[0027] Example 2: Figure 3 , Figure 4 and Figure 5 As shown, one end of the second support frame 2 is fixedly connected to a limiting post 7, and the outer side wall of the limiting post 7 is slidably connected to the inner side wall of the first support frame 1. Universal wheels 3 are fixedly connected to the bottom ends of both the first support frame 1 and the second support frame 2. Positioning frames 12 and support frames 13 are fixedly connected to the inner side walls of both the first support frame 1 and the second support frame 2, and a rotating shaft 19 is rotatably connected to the inner side walls of both the first support frame 1 and the second support frame 2. A base 17 is fixedly connected to the top of the positioning frame 12, and a rocker arm 16 is rotatably connected to the side wall of the support frame 13. A spring 18 is fixedly connected between the rocker arm 16 and the base 17. A rotating shaft 19 is located above the rocker arm 16, and a knob 11 is fixedly connected to one end of the rotating shaft 19. An involute swing wheel 10 is fixedly connected to the outer side wall of the rotating shaft 19. A limiting plate 15 is fixedly connected to the outer side wall of the rocker arm 16, and the involute swing wheel 10 overlaps with the limiting plate 15. A striking plate 14 is fixedly connected between the two rocker arms 16.

[0028] The overall effect of this embodiment is that when the bridge shell material on the conveyor belt gets clogged during the feeding process, it is necessary to increase the slope to obtain a larger gravity component and control the smooth feeding of the bridge shell material. Before this, the material on the surface of the conveyor belt needs to be cleaned. A rotating shaft 19 is installed at the bottom of the support plate 6. One end of the rotating shaft 19 is fixed to the upright 1 or upright 2 via an extension arm. The knob 11 is turned by hand, which drives the rotating shaft 19 to rotate. The rotating shaft 19 drives the involute pendulum wheel 10 to rotate. When the involute pendulum wheel 10 rotates, the distance between its outer periphery and the axis of rotation increases, causing the involute pendulum wheel 10 to push open the limiting plate 15, causing the limiting plate 15 to sway. The swing arm 16 rotates downward, bringing it closer to the base 17 and compressing the spring 18. The outer periphery of the involute swing wheel 10 connects at its maximum and minimum positions. After the outer periphery of the rotating shaft reaches its maximum position, the swing arm 16 receives the elastic force of the spring 18 and moves upward at a high speed until the striking plate 14 strikes the bottom surface of the support plate 6, causing the support plate 6 to shake off the material above the conveyor belt. At the same time, the limiting plate 15 again comes into contact with the periphery of the involute swing wheel 10 at a closer distance. Each rotation causes the striking plate 14 to strike the support plate 6 once, thereby shaking off the material that has accumulated and blocked the conveyor belt. After the material in the bridge housing is cleaned, the slope of the conveyor belt is adjusted.

[0029] The method of use and working principle of this device: This support mechanism is installed below the raw material conveyor belt of the melting equipment, which includes a first support frame 1 and a second support frame 2. The two support plates 6 are in direct contact with the conveyor belt and the angle can be freely adjusted. Because the top heights of the first support frame 1 and the second support frame 2 are different, the support plates 6 form a slope difference. The bridge shell raw material is added from the high point of the conveyor belt by utilizing the slope gravity effect and then spontaneously moves downward into the inner cavity of the melting equipment.

[0030] By rotating the threaded screw 4, which is rotatably engaged with the second upright 2 and threadedly connected to the threaded seat 5, the distance between the first upright 1 and the second upright 2 can be adjusted, thereby adjusting the slope of the support plate 6 to fit against the conveyor belt and realize the feeding of the bridge shell raw material.

[0031] When the material feed into the bridge housing becomes clogged, first clean the material from the surface of the conveyor belt. Then, rotate the knob 11 to drive the rotating shaft 19 to rotate. The rotating shaft 19 drives the involute swing wheel 10 to rotate. The distance between the outer periphery of the involute swing wheel 10 and the axis of rotation increases in an involute manner, opening the limit plate 15. This causes the rocker arm 16 to rotate downwards and compress the spring 18. After passing the maximum position of the outer periphery of the involute swing wheel 10, the rocker arm 16 moves upwards at high speed due to the elastic force of the spring 18. The striking plate 14 hits the bottom surface of the support plate 6 and shakes off the material. The striking plate hits once every one rotation. After the material is cleaned up, the slope of the conveyor belt is adjusted.

[0032] In addition, the support mechanism is also equipped with omnidirectional wheels 3, limit posts 7, hinge seats 8, rotating disks 9, positioning frames 12, support frames 13, bases 17 and other components, each of which plays a corresponding role and together ensures the normal operation of the entire support mechanism and the realization of functions related to material conveying and unloading.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
