Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically a suspension chain through-type shot blasting machine. Background Technology

[0002] The overhead conveyor shot blasting machine is an important piece of equipment widely used in industries such as machinery manufacturing, automobiles, tractors, diesel engines, motors, and valves. The workpiece is suspended on the overhead conveyor by hooks and enters the shot blasting chamber as the conveyor moves. The high-speed rotating shot wheel throws shot at the surface of the workpiece. It is mainly used to clean the surface of the workpiece of rust, welding slag, oxide scale and other attachments. At the same time, it can also eliminate welding stress on the workpiece, improve the fatigue strength of the workpiece, and increase the adhesion of the paint film when the workpiece is painted.

[0003] Reference patent document: Patent Publication No. N212665836U, Patent Publication Date 2021-03-09, includes a overhead conveyor belt, a shot blasting machine installed below the overhead conveyor belt, a fixing block 1 fixedly connected inside the overhead conveyor belt, a hook assembly installed below the fixing block 1, a buckle fixing device provided on the circumferential side of the hook assembly, and connecting fixing devices provided on the left and right sides of the hook assembly, the hook assembly includes a fixing block 2, the upper surface of the fixing block 2 is fixedly connected to the lower surface of the fixing block 2, and rectangular blocks 1 are fixedly connected to both ends of the circumferential side of the fixing block 2, the rectangular blocks 1 have a rectangular groove 1 inside, allowing users to replace different types of hangers to fix different equipment, the upper ends of different types of hangers can be firmly fixed by fixing collars, the disassembly and fixing of hangers are more convenient, and users with different equipment can use them more flexibly.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] Currently, most overhead conveyor shot blasting machines use fixed suspension or rigid connection to transport workpieces into the shot blasting chamber. The workpieces maintain a single posture throughout the shot blasting process and cannot be fully exposed to the shot blasting area. For workpieces with complex structures (grooves, blind holes, corners), the shot cannot reach parts of the surface because some surfaces are blocked by their own structure, resulting in cleaning blind spots and making it impossible to achieve thorough surface cleaning. The fixed angle also causes the shot blasting position to be fixed, which may also cause excessive impact on the workpiece surface, resulting in surface damage and reduced workpiece strength.

[0006] Therefore, this utility model provides a suspension chain through shot blasting machine. Utility Model Content

[0007] To address the problem that most overhead conveyor shot blasting machines use fixed suspension or rigid connection to transport workpieces into the shot blasting chamber, which makes it impossible to adjust the angle and position of the workpieces, easily creating blind spots and affecting the cleaning effect, the purpose of this utility model is to provide an overhead conveyor shot blasting machine.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a overhead conveyor shot blasting machine, comprising a shot blasting chamber, wherein a deflection mechanism is provided on one side of the shot blasting chamber for adjusting the angle and position of the workpiece requiring surface cleaning. The deflection mechanism includes:

[0009] The angle adjustment assembly includes a first rotating bracket located at the bottom of the conveying equipment in the shot blasting chamber.

The middle part of the rotating rod is rotatably mounted on the middle part of the second rotating bracket. A drive assembly is provided at the top of the first rotating bracket.

[0010] The horizontal rotation component, located on the upper part of the first rotating bracket, is used to adjust the horizontal angle position of the workpiece.

[0011] Preferably, the horizontal rotating assembly includes a protective cover fixed to the lower part of the conveying equipment in the shot blasting chamber, a first rotating bracket rotatably mounted at the bottom of the protective cover, a drive disk in the middle of the protective cover, the top of a first rotating shaft fixedly mounted at the bottom middle of the drive disk, a driven disk on one side of the drive disk, a drive block fixedly mounted on one side of the bottom of the drive disk, a plurality of drive grooves that cooperate with the drive block on the upper part of the driven disk, and a transmission assembly at the bottom of the drive disk.

[0016] Beneficial effects

[0017] This utility model provides a overhead conveyor shot blasting machine. Compared with the prior art, it has the following advantages:

[0018] 1. This application uses a servo motor to drive the cam to rotate, causing the rotating rod to rotate eccentrically, thereby driving the deflection plate to adjust the angle in the up and down direction. This allows the workpiece to continuously change its posture in the shot blasting chamber, effectively eliminating the cleaning blind spots caused by a fixed posture. It can also fully cover workpieces with complex structures such as those containing grooves, blind holes, and corners with high-speed shot, effectively removing impurities from the workpiece surface.

[0019] 2. This application uses a servo motor to drive the drive disk to rotate, which in turn causes the eccentrically mounted drive block to rotate. In cooperation with the driven disk, multiple workpieces are intermittently rotated through the transmission of the first gear and the second gear, thereby adjusting the position between the workpieces and further improving the efficiency and quality of cleaning impurities from the workpiece surface.

[0027] 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.

[0028] Please see Figure 1-6 This utility model provides a technical solution: a overhead conveyor shot blasting machine, including a shot blasting chamber 1. A deflection mechanism 2 is provided on one side of the shot blasting chamber 1 for adjusting the angle and position of the workpiece that needs surface cleaning. The overhead conveyor shot blasting machine mainly consists of a suspended conveyor, a shot blasting chamber 1, a dust removal device, an electrical control system, and other components. The deflection mechanism 2 is installed below the suspended conveyor. By installing the workpiece at the lower part of the deflection mechanism 2, the workpiece is conveyed under the drive of the suspended conveyor to the deflection mechanism 2, thus entering the shot blasting chamber 1. High-speed rotating shot wheels propel shot onto the surface of the workpiece to clean surface impurities. The deflection mechanism 2 includes:

[0029] The angle adjustment assembly 21 includes a first rotating bracket 211 located at the lower part of the conveying equipment in the shot blasting chamber 1. The first rotating bracket 211 is integrally formed from high-strength alloy steel and has excellent impact resistance. A first rotating shaft 215 is rotatably mounted on the upper part of the first rotating bracket 211. A cam 214 is fixedly mounted on the bottom end of the first rotating shaft 215. The cam 214 is treated by carburizing and quenching. One side of the cam 214 is tilted downward to ensure that the rotating rod 213 installed at the lower part has an inclined angle, ensuring a precise angle adjustment trajectory, so that the end of the deflection plate 216 can move up and down. A rotating rod 213 is fixedly mounted on one side of the bottom end of the cam 214. A deflection plate 216 is fixedly mounted on the bottom end of the rotating rod 213. A second rotating bracket 212 is rotatably mounted on the lower part of the first rotating bracket 211. The middle part of the rotating rod 213 is rotatably mounted on the middle part of the second rotating bracket 212. A drive assembly is provided at the top of the first rotating bracket 211.

[0030] The horizontal rotation component 22 is located on the upper part of the first rotating bracket 211 and is used to adjust the horizontal angle position of the workpiece.

[0031] The horizontal rotation assembly 22 includes a protective cover 229 fixed to the lower part of the conveying equipment in the shot blasting chamber 1, a first rotating bracket 211 rotatably mounted on the bottom end of the protective cover 229, a drive disk 222 in the middle of the protective cover 229, the top end of a first rotating shaft 215 fixedly mounted on the bottom middle of the drive disk 222, a driven disk 221 on one side of the drive disk 222, a drive block 225 fixedly mounted on one side of the bottom end of the drive disk 222, a plurality of drive grooves 226 that cooperate with the drive block 225 on the upper part of the driven disk 221, and a transmission assembly at the bottom end of the drive disk 222. By setting the horizontal rotation assembly 22, the workpiece can be intermittently rotated horizontally during processing, thereby adjusting the position of the tool in the shot blasting chamber.

[0032] The transmission assembly includes a second gear 2271 fixed at the bottom of the drive disk 222, a first gear 227 fixedly mounted at the bottom of the driven disk 221, the first gear 227 and the second gear 2271 meshing with each other, a second rotating shaft 228 fixedly mounted at the bottom of the second gear 2271, the top center of the first rotating bracket 211 fixedly mounted at the bottom of the second rotating shaft 228, and the first rotating shaft 215 slidingly passing through the second rotating shaft 228.

[0033] The drive assembly includes a servo motor 2291 fixedly installed in the middle of the protective cover 229. The top of the drive disk 222 is fixedly installed on the drive end of the servo motor 2291. The servo motor 2291 is a low-inertia permanent magnet synchronous motor. The driver can be connected to a host computer control system such as a PLC or industrial computer through a communication interface to control the rotation of the servo motor 2291, thereby controlling the angle and position adjustment of the workpiece and ensuring that impurities on the surface of the workpiece can be cleaned efficiently and uniformly.

[0034] A limit block 223 is fixedly installed at the bottom of the drive disk 222. Several limit grooves 224 are provided on the outer side of the driven disk 221 to cooperate with the limit block 223, so as to limit the driven disk 221 and ensure that the driven disk 221 will not rotate after the drive block 225 deviates from the drive groove 226.

[0035] The bottom of the deflection plate 216 is provided with multiple evenly distributed mounting positions. Each mounting position can be detachably mounted with a workpiece fixing hook 217. The detachable design allows for easy replacement of the workpiece fixing hook 217, thus facilitating the fixing of unused workpieces.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] During operation, the workpiece whose surface needs to be cleaned by shot blasting chamber 1 is fixed on the workpiece fixing hook 217, and transported by the suspension conveyor above shot blasting chamber 1 so that it enters shot blasting chamber 1. The high-speed rotating shot wheel throws shot at the surface of the workpiece to clean the surface impurities.

[0038] Meanwhile, driven by the servo motor 2291, the drive disk 222 rotates, which in turn drives the drive block 225 to rotate. The drive block 225 intermittently slides and locks itself in the drive groove 226, thereby intermittently driving the driven disk 221 to rotate, which in turn drives the first gear 227 to rotate, which in turn drives the meshing second gear 2271 to rotate, causing the second rotating shaft 228 to rotate, which in turn drives the first rotating bracket 211 to rotate, causing the deflection plate 216 to rotate intermittently horizontally, thus adjusting the position of the tool.

[0039] Simultaneously, the rotation of the drive disc 222 drives the first rotating shaft 215 to rotate, which in turn drives the cam 214 to rotate. Under the rotation limit of the first rotating bracket 211 and the second rotating bracket 212, the deflection plate 216 deflects at an angle, and the end height of the deflection plate 216 keeps moving up and down, thereby driving the tool to adjust its up and down angle position, so that its high-speed rotating shot wheel can evenly throw the shot onto the surface of the workpiece.
