Description

Technical Field

[0001] This invention relates to the field of processing equipment for engineering machinery parts, and specifically discloses a conveying device for processing excavator track plates. Background Technology

[0002] During the production and processing of excavator track shoes, a conveyor system is needed to transport the track shoes sequentially to processing stations such as punching, milling, or heat treatment. Currently, the most commonly used conveyor system is a chain conveyor, which moves the track shoes via a chain belt.

[0003] However, existing conveying devices have the following technical problems in practical applications: First, when the track plates are transported to the processing station, they usually rely on inertial impact to stop the positioning baffle. Due to the lack of a buffer structure, the impact force is large, which not only easily causes damage to the surface of the track plates, but also causes inaccurate positioning due to rebound, affecting the subsequent processing accuracy.

[0004] Secondly, during the conveying process, the track plates are prone to lateral displacement due to the vibration of the chain belt or the irregular shape of the track plates themselves, which causes deviation in their relative position with the processing equipment. This requires frequent manual adjustments, reducing production efficiency and processing consistency. Summary of the Invention

[0005] This invention proposes a conveying device for processing excavator track plates. It achieves flexible buffering and positioning through a floating buffer mechanism and automatic lateral correction through a correction and adjustment mechanism. This effectively solves the problems of impact damage and positional deviation during the conveying process of track plates, and improves processing accuracy and production efficiency.

[0006] This invention is implemented as follows: a conveying device for processing excavator track plates includes a chain conveyor and a chain belt rotatably mounted on the chain conveyor. The chain belt consists of a chain and a plurality of chain plates fixed at intervals on the chain. The device also includes: A floating buffer mechanism is provided on each of the chain plate components, comprising a mounting base, at least two guide telescopic rods, a buffer baffle, and an elastic buffer member; the mounting base is fixedly connected to the upper surface of the chain plate component; at least two guide telescopic rods are symmetrically arranged between the mounting base and the buffer baffle, one end of each guide telescopic rod is connected to the mounting base, and the other end is connected to the buffer baffle; the elastic buffer member is sleeved on the outside of the guide telescopic rod, with its two ends abutting against the mounting base and the buffer baffle respectively, for absorbing the impact energy when the track plate impacts; The correction and adjustment mechanism includes fixed frames symmetrically installed on the frames on both sides of the chain conveyor. Each fixed frame is provided with a telescopic drive component. The output end of the telescopic drive component is fixedly connected to a correction push plate. The two correction push plates are arranged opposite to each other and are used to correct the lateral position of the track plates during conveying.

[0007] In a preferred embodiment of the conveying device for processing excavator track plates according to the present invention, the guide telescopic rod includes a fixed sleeve and a sliding rod. One end of the fixed sleeve is fixedly mounted on the mounting base, one end of the sliding rod is slidably embedded in the other end of the fixed sleeve, and the other end of the sliding rod is fixedly connected to the buffer baffle.

[0008] As a preferred embodiment of the conveying device for processing excavator track plates according to the present invention, the floating buffer mechanism further includes a damper, which is disposed between the mounting base and the buffer baffle to reduce the rebound speed of the buffer baffle.

[0009] In a preferred embodiment of the conveying device for processing excavator track plates according to the present invention, the straightening push plate has an installation groove on its side facing the track plate, and a distance sensor is embedded in the installation groove, with the detection end of the distance sensor facing the track plate on the chain belt.

[0010] In a preferred embodiment of the conveying device for processing excavator track plates according to the present invention, the telescopic drive component is an electric telescopic rod or a cylinder.

[0011] In a preferred embodiment of the conveying device for processing excavator track plates according to the present invention, the buffer baffle is covered with a polyurethane elastic layer on the side away from the guide telescopic rod, and the straightening push plate is covered with a rubber pad on the side facing the track plate.

[0012] The beneficial effects of this invention are: 1. By setting a floating buffer mechanism on each track plate component, the elastic buffer absorbs the impact energy when the track plate hits, and the damper slows down the rebound speed, which effectively avoids damage to the track plate surface, while ensuring the accuracy of the track plate's stopping position and significantly improving the subsequent processing accuracy.

[0013] 2. By symmetrically setting correction and adjustment mechanisms on both sides of the chain conveyor, the telescopic drive component drives the correction push plate to automatically correct the lateral position of the conveyor track plates. No manual intervention is required, which effectively solves the problem of offset caused by vibration or irregular shape, and improves production efficiency and processing consistency.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0020] Please see Figure 1-3 A conveying device for processing excavator track plates includes a chain conveyor 1 and a chain belt 2 rotatably mounted on the chain conveyor 1. The chain belt 2 consists of a chain 3 and a plurality of chain plate components 4 fixed at intervals on the chain 3. The device also includes: A floating buffer mechanism is provided on each chain plate component 4, which includes a mounting base 5, at least two guide telescopic rods 6, a buffer baffle 7, and an elastic buffer element 8. The mounting base 5 is fixedly connected to the upper surface of the chain plate component 4. At least two guide telescopic rods 6 are symmetrically arranged between the mounting base 5 and the buffer baffle 7. One end of the guide telescopic rod 6 is connected to the mounting base 5, and the other end is connected to the buffer baffle 7. The elastic buffer element 8 is sleeved on the outside of the guide telescopic rod 6, and its two ends abut against the mounting base 5 and the buffer baffle 7 respectively, for absorbing the impact energy when the track plate hits. The correction and adjustment mechanism includes fixed frames 9 symmetrically installed on the frames on both sides of the chain conveyor 1. Each fixed frame 9 is provided with a telescopic drive component 10. The output end of the telescopic drive component 10 is fixedly connected to a correction push plate 11. The two correction push plates 11 are arranged opposite to each other and are used to correct the lateral position of the track plates during conveying.

[0021] In this embodiment: when the track plate is conveyed forward with the chain belt 2 under the drive of the chain conveyor 1, the front end of the track plate first contacts the buffer baffle 7 of the floating buffer mechanism. After the buffer baffle 7 is impacted, it compresses the elastic buffer member 8. At the same time, the guide telescopic rod 6 retracts axially. The elastic buffer member 8 absorbs the impact energy, so that the track plate decelerates smoothly and stops, realizing flexible buffer positioning. Meanwhile, when the track plate deviates laterally during the conveying process, the telescopic drive member 10, which is symmetrically installed on the frame on both sides of the chain conveyor 1, drives the correction push plate 11 to extend inward synchronously. The two oppositely arranged correction push plates 11 push against the side wall of the track plate from both sides, correcting the track plate to the preset conveying center line position, thereby completing the lateral position correction during the conveying process.

[0022] As a technical optimization of the present invention, the guide telescopic rod 6 includes a fixed sleeve 12 and a sliding rod 13. One end of the fixed sleeve 12 is fixedly mounted on the mounting base 5, and one end of the sliding rod 13 is slidably embedded in the other end of the fixed sleeve 12. The other end of the sliding rod 13 is fixedly connected to the buffer baffle 7.

[0023] In this embodiment, the stability and guiding accuracy of the extension and retraction movement of the buffer baffle 7 are ensured by fixing the sleeve 12 and the sliding rod 13, thus avoiding deflection.

[0024] As a technical optimization of the present invention, the floating buffer mechanism further includes a damper 14, which is disposed between the mounting base 5 and the buffer baffle 7 to slow down the rebound speed of the buffer baffle 7.

[0025] In this embodiment, by adding a damper 14, the rebound speed of the buffer baffle 7 after being compressed is slowed down, preventing the track plate from causing secondary impact or positioning deviation due to rebound, thereby improving positioning stability.

[0026] As a technical optimization of the present invention, the straightening push plate 11 has a mounting groove 15 on the side facing the track plate, and a distance sensor 16 is embedded in the mounting groove 15. The detection end of the distance sensor 16 faces the track plate on the chain belt 2.

[0027] In this embodiment: by adding a distance sensor 16 to the correction push plate 11, the lateral position of the track plate can be detected in real time, providing signal feedback for automatic correction and realizing intelligent control.

[0028] As a technical optimization of the present invention, the telescopic drive component 10 is an electric telescopic rod or a cylinder.

[0029] In this embodiment, the specific type of the telescopic drive component 10 (electric telescopic rod or cylinder) and the driving method are clearly defined to facilitate feature comparison during infringement determination.

[0030] As a technical optimization of the present invention, the side of the buffer baffle 7 away from the guide telescopic rod 6 is covered with a polyurethane elastic layer 17, and the side of the corrective push plate 11 facing the track plate is covered with a rubber pad 18.

[0031] In this embodiment, elastic material layers (polyurethane elastic layer 17 and rubber pad 18) are added to the working surfaces of the buffer baffle 7 and the straightening push plate 11 respectively to reduce hard contact with the track plate, prevent surface scratches, and increase friction to assist in positioning and correction.

[0032] Working principle and usage process of this invention: After the equipment starts, the chain conveyor 1 drives the chain belt 2 and its multiple chain plate components 4 to rotate in a cycle. The track plates are placed on the chain plate components 4 and conveyed forward with the chain belt 2. When the track plates are conveyed to the processing station, the front end of the track plate contacts the buffer baffle 7 of the floating buffer mechanism set on the chain plate component 4. After the buffer baffle 7 is impacted, the guide telescopic rod 6 retracts and compresses the elastic buffer component 8. The elastic buffer component 8 absorbs the impact energy, so that the track plate decelerates smoothly until it stops. At the same time, the damper 14 slows down the rebound speed of the buffer baffle 7, ensuring that the track plate stops stably at the preset processing position. Position; During the conveying process, when the track plate shifts laterally due to vibration or irregular shape, the distance sensors 16, symmetrically installed on both sides of the frame of the chain conveyor 1, detect the track plate position shift signal. The control system controls the telescopic drive component 10 to start, driving the straightening push plate 11 to extend inward synchronously. The two oppositely arranged straightening push plates 11 push against the side walls of the track plate from both sides, pushing the track plate to the conveying center line position. After the straightening is completed, the telescopic drive component 10 drives the straightening push plate 11 to reset. This cycle is repeated to realize the flexible buffer positioning and automatic straightening conveying of the track plate.
