Description

Technical Field

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

[0002] The shot blasting device is the core component of the shot blasting machine. It belongs to the category of machining equipment and is widely used in the fields of casting, forging and metal surface treatment. It is mainly used to clean the oxide scale, remove rust and strengthen the surface of workpieces by high-speed blasting of steel shot, quartz sand and other media. Its core structure includes blades, guard plates, directional sleeves and shot distribution wheels.

[0003] The existing Chinese utility model patent with publication number CN206632869U discloses an automatic shot blasting angle adjustment device, including a housing, a shot blasting device, and a shot blasting angle adjustment device. The shot blasting device is disposed inside the housing and is used to blast shot onto workpieces disposed inside the housing. The shot blasting angle adjustment device is connected to the shot blasting device and is used to adjust the trajectory of the shot blasted by the shot blasting device. By setting up the shot blasting angle adjustment device, the shot blasting angle is automatically adjusted when shot blasting workpieces of different structures and sizes is performed, thereby solving the problem of the difficulty of manual adjustment, reducing the professional technical requirements of operators, saving labor costs, and ensuring that most of the shot blasted acts on the surface of the workpiece, thus avoiding damage to the equipment caused by shot blasting on the inner wall of the equipment.

[0004] The shot blasting machine described above adjusts the shot blasting angle by using a cylinder to adjust the position of the orifice of the directional sleeve. One end of the cylinder is hinged to the outer shell, and the other end is hinged to one end of the directional sleeve. The overall tilt angle of the cylinder is small. During the extension and retraction process, the cylinder directly pushes and pulls the directional sleeve, which will cause excessive local stress on the directional sleeve and generate additional bending moment. This makes it easy for the directional sleeve to deform under stress during rotation. At the same time, the angle change that the directional sleeve can produce in this way is limited by the positional relationship between the fixed end of the cylinder and the axis of the directional sleeve. When the extended line of the cylinder axis coincides with the tangential diameter of the directional sleeve, the cylinder will not be able to drive the directional sleeve to rotate. The maximum angle that the cylinder can adjust is small, and the adjustment range is small. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sandblasting device for a through-type shot blasting machine, which solves the problems of small adjustment range and excessive local stress on the directional sleeve.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A sandblasting device for a through-type shot blasting machine includes a housing, and a shot blasting mechanism is disposed above the housing.

[0007] The adjustment assembly includes a connecting frame fixedly installed on the top of the housing, a fixed frame movably installed above the connecting frame, a connecting cylinder movably installed at one end of the fixed frame, a support block movably installed at the bottom end of the connecting cylinder, a limit frame fixedly installed on the front side of the housing, and a transmission cylinder movably installed on one side of the limit frame.

[0008] The drive assembly, located inside the housing, is used to rotate the steel shot and throw it out using centrifugal force.

[0009] Preferably, the fixed frame and the connecting frame are rotatably connected, one end of the connecting cylinder is rotatably connected to the fixed frame bracket, and the other end is rotatably connected to the support block.

[0010] Preferably, the bottom end of the support block is fixed to the top end of the outer shell, and one end of the transmission cylinder is rotatably connected to the limiting structure.

[0011] Preferably, the drive assembly includes an inner liner fixedly installed inside the outer casing, a shot distribution wheel inserted through the rear side of the inner liner, a directional sleeve inserted through the front side of the inner liner, and a support frame fixedly installed on the front side of the outer casing. A bearing is fitted inside the support frame, a shot chute is inserted inside the bearing, an impeller is fixedly installed on the outer side of the shot distribution wheel, and a drive motor is provided at the rear end of the shot distribution wheel.

[0012] Preferably, the shot-dividing wheel is inserted inside the directional sleeve and forms a rotatable connection with the directional sleeve. The length of the shot-dividing wheel is greater than that of the directional sleeve, and the rear end of the shot-dividing wheel is provided with an annular protrusion structure.

[0013] Preferably, the rear end of the impeller is fixed to the outside of the annular protrusion structure at the rear end of the shot separator, and the opening structure at the center of the impeller is larger than the directional sleeve. One end of the directional sleeve is provided with a symmetrical protrusion structure, and one side of the protrusion structure of the directional sleeve is provided with a columnar structure.

[0014] Beneficial effects

[0015] This utility model provides a sandblasting device for a through-type shot blasting machine. Compared with the prior art, it has the following advantages:

[0016] (1) The sandblasting device for the through shot blasting machine has a directional sleeve. One end of the directional sleeve has a symmetrical protrusion structure, and one side of the protrusion structure of the directional sleeve has a columnar structure. The columnar structure of the directional sleeve is connected to the moving end of the transmission cylinder. This method distributes the pressure to the two junction points through the protrusion structures on both sides of the directional sleeve, avoiding excessive concentrated stress on one side of the directional sleeve. At the same time, the transmission cylinders on the upper and lower sides are symmetrical and mirrored on the left and right sides, which can make the directional sleeve more evenly stressed during rotation, offsetting lateral forces and off-center loads, reducing local stress concentration caused by uneven stress, and preventing deformation of the directional sleeve during angle adjustment.

[0017] (2) The sandblasting device for the through shot blasting machine is set with a fixed frame. One end of the fixed frame is connected to the outer shell through a connecting frame, and the other end is connected to the support block on the top of the outer shell through a connecting cylinder. When the connecting cylinder extends and retracts, its tilt angle changes, and at the same time, it drives the outer shell to rotate around the axis of the columnar structure at the top of the connecting frame, thereby adjusting the orientation of the drive components inside the lower outer shell. At the same time, one end of the directional sleeve is provided with a symmetrical protrusion structure, and the columnar structure on one side is rotatably connected to the movable end of the transmission cylinder. The angle can be adjusted by the drive of the transmission cylinder to expand the adjustment range. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a sandblasting device for a through-type shot blasting machine includes a housing 1, and a shot blasting mechanism 2 is arranged above the housing 1.

[0025] The adjustment assembly 21 includes a connecting frame 211 fixedly installed on the top of the outer casing 1, a fixed frame 212 movably installed above the connecting frame 211, a connecting cylinder 213 movably installed at one end of the fixed frame 212, a support block 214 movably installed at the bottom end of the connecting cylinder 213, a limit frame 215 fixedly installed on the front side of the outer casing 1, a transmission cylinder 216 movably installed on one side of the limit frame 215, a rotatable connection between the fixed frame 212 and the connecting frame 211, a rotatable connection between one end of the connecting cylinder 213 and the support frame 212, and a rotatable connection between the other end of the connecting cylinder 213 and the support block 214, the bottom end of the support block 214 being fixed to the top of the outer casing 1, and a rotatable connection between one end of the transmission cylinder 216 and the limit frame 215.

[0026] Specifically, by fixing the mounting bracket 212 to the mounting surface with bolts, the position of the lower outer shell 1 can be restricted. One end of the mounting bracket 212 is rotatably connected to the outer shell 1 through the connecting bracket 211, and the other end is connected to the support block 214 on the top of the outer shell 1 through the connecting cylinder 213. When the connecting cylinder 213 extends or retracts, its tilt angle changes, and at the same time, it drives the outer shell 1 to rotate around the axis of the cylindrical structure at the top of the connecting bracket 211, thereby adjusting the orientation of the drive component 22 inside the lower outer shell 1. The limiting bracket 215 can restrict the position of one end of the transmission cylinder 216, and the transmission cylinder 216 can drive the directional sleeve 223 to rotate to adjust the position of the steel shot being thrown.

[0027] The drive assembly 22, located inside the outer casing 1, is used to drive the steel shot to rotate and eject it using centrifugal force. The drive assembly 22 includes an inner liner 221 fixedly installed inside the outer casing 1. A shot distribution wheel 222 is inserted through the rear side of the inner liner 221, and a directional sleeve 223 is inserted through the front side of the inner liner 221. The drive assembly 22 also includes a support frame 224 fixedly installed on the front side of the outer casing 1. A bearing 225 is fitted inside the support frame 224, and a shot chute 226 is inserted through the bearing 225. An impeller 227 is fixedly installed on the outer side of the shot distribution wheel 222, and a drive motor is located at the rear end of the shot distribution wheel 222. Machine 228, the shot distribution wheel 222 is inserted inside the directional sleeve 223 and is rotatably connected to the directional sleeve 223. The length of the shot distribution wheel 222 is greater than that of the directional sleeve 223. The rear end of the shot distribution wheel 222 is provided with an annular protrusion structure. The rear end of the impeller 227 is fixed to the outside of the annular protrusion structure at the rear end of the shot distribution wheel 222. The opening structure at the center of the impeller 227 is larger than that of the directional sleeve 223. One end of the directional sleeve 223 is provided with a symmetrical protrusion structure. One side of the protrusion structure of the directional sleeve 223 is provided with a columnar structure. The columnar structure of the directional sleeve 223 is rotatably connected to the movable end of the transmission cylinder 216.

[0028] Specifically, steel shot falls into the shot distribution wheel 222 through the shot chute 226. The shot distribution wheel 222 rotates at high speed driven by the drive motor 228, and the centrifugal force evenly throws the steel shot into all directions, giving it initial speed and direction of motion, and conveying it to the entrance of the directional sleeve 223. The steel shot thrown out by the shot distribution wheel 222 arrives at the directional sleeve 223. One end of the directional sleeve 223 is provided with a symmetrical protrusion structure, and a cylindrical structure on one side is rotatably connected to the movable end of the transmission cylinder 216. The angle can be adjusted by driving the transmission cylinder 216. The shot chute 226 is rotatably connected to the support frame 224 through the bearing 225, and one end of the shot distribution wheel 222 is inserted into the bottom end of the shot chute 226. This can avoid affecting the connection between the shot chute 226 and the steel shot conveying pipeline when the angle of the outer shell 1 changes. The impeller 227 can drive the steel shot to rotate and throw the steel shot out through centrifugal force. The drive motor 228 can drive the shot distribution wheel 222 to rotate.

[0029] Specifically, the drive motor 228 is model YBK3, the connecting cylinder 213 is model FYZ-36A, and the transmission cylinder 216 is model SCA2-00-50B-70. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] During operation, one end of the directional sleeve 223 has a symmetrically shaped protrusion, and one side of the protrusion has a cylindrical structure. The cylindrical structure of the directional sleeve 223 forms a rotatable connection with the movable end of the transmission cylinder 216. This method distributes pressure to two junction points through the protrusions on both sides of the directional sleeve 223, preventing excessive stress concentration on one side of the directional sleeve 223. Simultaneously, the transmission cylinders 216 on both sides are symmetrically arranged vertically and horizontally, ensuring more balanced force distribution on the directional sleeve 223 during rotation. This counteracts lateral forces and eccentric loads, reducing local stress concentration caused by uneven force distribution, and preventing the directional sleeve 223 from rotating at an angle. During the adjustment process, deformation occurs. One end of the fixed frame 212 is rotatably connected to the outer shell 1 through the connecting frame 211, and the other end is connected to the support block 214 on the top of the outer shell 1 through the connecting cylinder 213. When the connecting cylinder 213 extends or retracts, its tilt angle changes, which in turn drives the outer shell 1 to rotate around the axis of the cylindrical structure at the top of the connecting frame 211 as a reference. This adjusts the orientation of the drive component 22 inside the lower outer shell 1. At the same time, one end of the directional sleeve 223 is provided with a symmetrical protrusion structure, and the cylindrical structure on one side is rotatably connected to the movable end of the transmission cylinder 216. The angle can be adjusted by the drive of the transmission cylinder 216 to expand the adjustment range.
