Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically to a workpiece turning device for a mesh belt through shot blasting machine. Background Technology

[0002] In modern manufacturing, surface treatment of metal workpieces is a crucial step in ensuring product quality and performance. Shot blasting machines, as a commonly used surface treatment equipment, remove oxide scale, rust, dirt, and other impurities from the workpiece surface by blasting high-speed shot onto it. Simultaneously, they strengthen the workpiece surface, improving its fatigue strength and corrosion resistance. Mesh belt through-type shot blasting machines, due to their ability to achieve continuous production, are suitable for batch processing of small to medium-sized workpieces and are widely used in industries such as machinery manufacturing, automotive parts processing, hardware products, and casting.

[0003] In the prior art, such as in publication number CN213828575U, a mesh belt shot blasting machine is disclosed. It includes a base, an isolation mechanism, a shot blaster, a roller, and a filtering mechanism. Supports are fixed to both the front and rear sides of the upper surface of the base. The conveyor belt device has a through-opening. The isolation mechanism includes a limiting block, a baffle, and a shaft, with the limiting block fixed to the top of the opening. The shot blaster is fixed to the inner top of the support frame, and a shot blasting gun is fixed through-fixed to the bottom of the shot blaster. In this mesh belt shot blasting machine, after material is placed on the conveyor belt device, the conveyor belt device rotates, thereby moving the material to the right. Simultaneously, the roller rotates, facilitating the operation of the conveyor belt device and providing support. The shot blaster itself stores shot, which is ejected from the shot blasting gun to clean the surface of the material, facilitating the removal of oxide scale. The oxide scale then falls into the guide channel along with the shot through the porous conveyor belt device.

[0004] Based on the above-mentioned existing technology, in the actual shot blasting operation of the existing mesh belt shot blasting machine, because the workpiece is placed on the mesh belt and the bottom surface is blocked by the mesh belt support, it cannot come into contact with the high-speed shot. This makes it difficult to remove impurities such as oxide scale and rust on the bottom surface of the workpiece, thereby reducing the processing effect of the workpiece. To this end, the present invention provides a workpiece turning device for a mesh belt through shot blasting machine. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a workpiece turning device for a mesh belt shot blasting machine. This device solves the problem that in the actual shot blasting operation of existing mesh belt shot blasting machines, the bottom surface of the workpiece is blocked by the mesh belt and cannot come into contact with high-speed shot. This makes it difficult to remove impurities such as oxide scale and rust from the bottom surface of the workpiece, thus reducing the processing effect of the workpiece.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a workpiece turning device for a mesh belt through-type shot blasting machine, comprising a housing, wherein the housing is equipped with a turning mechanism for turning the workpiece, the turning mechanism comprising:

[0012] Preferably, both telescopic components include cylinders mounted on a fixed base. The two cylinders are symmetrically distributed from left to right. The cylinders are arranged along the length of the fixed base. The telescopic end of the cylinder slides through the inner wall of the bracket and extends outward. A connecting block is fixedly installed on the telescopic end of the cylinder. A long strip is fixedly installed on the opposite side surface of the two connecting blocks. The long strip is located between two slide rails and has multiple adjustment holes arranged on it.

[0016] Beneficial effects

[0017] This utility model provides a workpiece turning device for a mesh belt through-type shot blasting machine. Compared with the prior art, it has the following advantages:

[0018] 1. The workpiece flipping device of this conveyor belt shot blasting machine can drive the rotating shaft to rotate by starting the motor. When the rotating shaft rotates, it can change the angle of the fixed seat, thereby causing the telescopic component and the clamping component to flip. Furthermore, the two telescopic components can drive the two clamping components to move closer or further apart, thereby realizing the clamping or releasing operation of the workpiece. When the clamping component clamps the workpiece, the rotation of the rotating shaft realizes the workpiece flipping operation, effectively solving the problem of difficult removal of impurities on the bottom surface of the workpiece and improving the workpiece processing effect.

[0019] 2. The workpiece turning device of this conveyor belt shot blasting machine can change the maximum or minimum distance between the two clamping components by unscrewing the first stud and installing it in the adjustment hole at a suitable position on the long strip, so as to adapt to the clamping operation of workpieces of different widths.

[0026] 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.

[0027] This utility model provides two technical solutions:

[0028] Figures 1-5 The first embodiment is shown: a workpiece turning device for a mesh belt shot blasting machine, including a housing 1, and a turning mechanism 2 for turning the workpiece inside the housing 1. The turning mechanism 2 includes:

[0029] A rotating assembly 21 is mounted on a chassis 1. The rotating assembly 21 includes a rotating shaft 212 that passes through and rotatably mounts on the chassis 1. The rotating shaft 212 is mounted along the width direction of the chassis 1. A fixed seat 213 is fixedly mounted on the outer wall of the rotating shaft 212 near the middle position. The fixed seat 213 is located inside the chassis 1. A bracket 214 is mounted on the outer surface of the fixed seat 213. Slide rails 215 are symmetrically mounted on the outer surface of the bracket 214.

[0030] Two telescopic components 22 are installed symmetrically on the fixed base 213;

[0031] Two clamping components 23 are installed on the two telescopic components 22 respectively.

[0032] The limiting component 24 is disposed outside the chassis 1 and is used to limit the rotation angle of the rotating shaft 212.

[0033] The rotating assembly 21 also includes a motor 211 mounted on the outer wall of one side of the chassis 1, and the output shaft end of the motor 211 is fixedly connected to the end of the rotating shaft 212.

[0034] Specifically, starting the motor 211 can drive the rotating shaft 212 to rotate. When the rotating shaft 212 rotates, it can change the angle of the fixed seat 213, thereby causing the telescopic component 22 and the clamping component 23 to flip. Furthermore, the two telescopic components 22 can drive the two clamping components 23 to move closer or further apart, thereby realizing the clamping or releasing operation of the workpiece. When the clamping component 23 clamps the workpiece, the rotating action of the rotating shaft 212 realizes the flipping operation of the workpiece.

[0035] In this embodiment, both telescopic components 22 include cylinders 221 mounted on the fixed base 213. The two cylinders 221 are symmetrically distributed from left to right. The cylinders 221 are arranged along the length of the fixed base 213. The telescopic end of the cylinder 221 slides through the inner wall of the bracket 214 and extends outward. A connecting block 222 is fixedly installed on the telescopic end of the cylinder 221. A strip 223 is fixedly installed on the opposite side surface of the two connecting blocks 222. The strip 223 is located between the two slide rails 215. Multiple adjustment holes 224 are arranged on the strip 223.

[0036] Specifically, the extension and retraction of the cylinders 221 in the two telescopic components 22 can drive the connecting blocks 222 to move closer or further away from each other, thereby causing the strips 223 to move closer or further away from each other. When the strips 223 move closer or further away from each other, they can drive the clamping components 23 to move closer or further away from each other.

[0037] Figures 1-5 The second embodiment is shown, and the main difference from the first embodiment is that the clamping assembly 23 includes an L-shaped fixing plate 231. A slider 232 that is slidably connected to the slide rail 215 is installed on the outer surface of one side of the L-shaped fixing plate 231. Two first studs 233 are provided through the inner wall of one side of the L-shaped fixing plate 231, and the first studs 233 are threadedly connected to the adjustment hole 224. A clamping plate 234 is provided on the inner wall of the other side of the L-shaped fixing plate 231. A second stud 235 is provided through the outer wall of the other side of the L-shaped fixing plate 231, and the second stud 235 is threadedly connected to the clamping plate 234.

[0038] Specifically, when the two clamping components 23 approach or move away from each other, the workpiece can be clamped or released by the clamping plate 234.

[0039] Furthermore, by unscrewing the first stud 233 and installing it in the adjustment hole 224 at a suitable position on the strip 223, the maximum or minimum distance between the two clamping components 23 can be changed, thereby adapting to workpiece clamping operations of different widths.

[0040] Furthermore, the second stud 235 allows for the disassembly or installation of the clamping plate 234, facilitating the replacement of different clamping plates 234 according to the shape of the workpiece and improving practicality.

[0041] In this embodiment, the limiting component 24 includes a limiting block 241 and a fixing block 242. The limiting block 241 is installed on the end face of the rotating shaft 212, and the fixing block 242 is installed on the outer wall of the chassis 1. The top surface of the fixing block 242 is in contact with the limiting block 241.

[0042] Specifically, when the rotating shaft 212 rotates to a suitable angle, the limiting block 241 contacts the fixed block 242, and the rotation angle of the rotating shaft 212 is limited by the limiting component 24, thereby preventing the rotating shaft 212 from overtravel and ensuring the smooth operation of the workpiece flipping.

[0043] In this embodiment, a mesh belt conveyor 11 is provided inside the chassis 1 below the flipping mechanism 2, and a shot blasting device 12 is symmetrically provided on the top of the chassis 1, with the shot blasting port of the shot blasting device 12 extending into the interior of the chassis 1.

[0044] Specifically, the two shot blasting devices 12 can perform shot blasting operations on workpieces at different positions. After the workpiece is flipped, the shot blasting device 12 located downstream of the machine housing 1 can perform shot blasting operations on the flipped workpiece.

[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0046] Working principle: When the mesh belt conveyor shot blasting machine is working, when the workpiece enters the machine box 1 with the mesh belt conveyor 11 and arrives at the flipping mechanism 2, the cylinders 221 in the two telescopic components 22 retract, causing the two strips 223 to move closer to each other. At the same time, the two adjusting clamping components 23 also move closer to each other and clamp the workpiece with the L-shaped fixing plate 231 and clamping plate 234. Then, the motor 211 is started, driving the rotating shaft 212 to rotate 180°, flipping the workpiece so that the bottom surface that was originally covered by the mesh belt is facing up. After that, the cylinder 221 extends and puts the workpiece back on the mesh belt conveyor 11 to continue to be conveyed forward.
