Description

Technical Field

[0001] The invention relates to the technical field of steel casting processing, in particular to a device for removing impurities from the surface of a steel casting. Background Art

[0002] In modern society, steel castings are common, which are usually made of metal melted at high temperatures. Most steel castings require additional processing after casting, and their surfaces require additional processing to remove impurities and defects.

[0003] Currently, medium-sized cylindrical steel castings, in most cases, require workers to use sandblasting guns to sandblast their surfaces to remove burrs and other defects on the surface, including oxide layers, rust caused by long-term contact with water in the air, etc. Sandblasting guns can remove surface burrs and other defects.

[0004] However, during use, workers need to be at a relatively close distance from the steel castings to use the sandblasting gun. However, the high-speed gravel sprayed out tends to rebound at high speed after hitting the steel castings, and the rebounded gravel is basically broken gravel with cutting properties. Even with the support of protective clothing, workers still face considerable safety risks. In addition, the thickness and inner diameter of most central cylindrical steel castings are different. During the sandblasting process, workers need to manually fix and turn them over, which increases time consumption and difficulty of operation. Summary of the invention

DETAILED DESCRIPTION

[0026] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention. The present invention is by no means limited to any specific configuration and algorithm proposed below, but covers any modification, replacement and improvement of elements, parts and algorithms without departing from the spirit of the present invention. In the accompanying drawings and the following description, known structures and technologies are not shown to avoid unnecessary ambiguity to the present invention.

[0027] Example 1

[0028] Reference Figure 1-3 , which is the first embodiment of the present invention, a device for removing impurities from the surface of a steel casting, comprises a support plate 1, the support plate 1 has two pieces, is a rectangular straight plate, is used to be fixed on the ground and support other components, a connecting end 11 is fixedly connected to the support plate 1, the connecting end 11 is used to connect the support plate 1 and the screw rod, and a motor seat 12 is fixedly connected to the support plate 1, and the motor seat 12 is used to install the motor;

[0029] It also includes a clamping structure arranged on one side of the support plate 1;

[0030] The clamping structure includes a mounting platform 21 arranged on one side of the support plate 1. The mounting platform 21 is a cylindrical truncated cone with a circular groove that does not penetrate the mounting platform 21. An extension groove 22 is provided on the mounting platform 21. The extension groove 22 is used to accommodate a top block 23. The top block 23 is slidably connected to the mounting platform 21. The top block 23 is composed of three parts. The upper part is a plate with an arc cross-section and thickness. One end of the plate is a fixedly connected toothed plate 24 for meshing with the driving gear 25. The other end is a common straight plate for limiting the top block 23 in the extended position. In the groove 22, there is a tooth plate 24 fixedly connected to the top block 23, a driving gear 25 arranged on one side of the tooth plate 24, and a driven gear 26 fixedly connected to the driving gear 25. The driven gear 26 and the driving gear 25 are fixedly connected by a rod, and the driving gear 25 is rotatably connected to the mounting platform 21 through the rod, and a driving gear 27 rotatably connected to the mounting platform 21 is engaged with the driving gear 27 and the driven gear 26. The driving gear 27 is driven by a first motor 28, and the first motor 28 is arranged on the driving gear 27.

[0031] The upper side of the top block 23 is rotatably connected to a roller 29, which is evenly arranged on the upper side of the top block 23 to enable the steel casting to rotate when it fits with the inner wall of the steel casting. The driving gear 25 is rotatably connected to the mounting platform 21 through a rod. The upper side of the first motor 28 is fixedly connected to a fixing sleeve 210, which is used to fix the first motor 28 in the straight rod 211.

[0032] A straight rod 211 is fixedly connected to the fixed sleeve 210, a central platform 212 is fixedly connected to one side of the straight rod 211, a first threaded sleeve 213 is fixedly connected to the central platform 212, and the first threaded sleeve 213 is used in conjunction with a one-way screw rod 214 to drive the mounting platform 21 on the central platform 212 and part of the structure thereon to enter the interior of steel castings of different lengths. The threads in the two first threaded sleeves 213 are in opposite directions, and when the one-way screw rod 214 rotates, the two first threaded sleeves 213 can be driven to move in opposite directions.

[0033] A one-way screw rod 214 is threadedly connected in the first threaded sleeve 213. One end of the one-way screw rod 214 is rotatably connected to the connecting end 11, and the other end is connected through a second motor 215. The second motor 215 drives the one-way screw rod 214 to rotate. A second motor 215 is provided on one side of the one-way screw rod 214, and the second motor 215 is fixedly connected to the support plate 1 through a motor base 12.

[0034] A telescopic rod 216 is fixedly connected to one side of the central platform 212. The telescopic rod 216 is used to limit the first threaded sleeve 213 so that it can move on the one-way screw rod 214 instead of rotating. The telescopic rod 216 is fixedly connected to the support plate 1, and a sandblasting structure with the function of rotating the cast steel part is set on the mounting platform 21.

[0035] During use, the steel casting needs to be placed on the same straight line as the two mounting platforms 21 and in the middle of the device. The above positions can be as close as possible. The device has a fine-tuning effect, and the steel casting can be adjusted to the position on the same straight line of the two mounting platforms 21. Then the second motor 215 is started, and the second motor 215 drives the one-way screw 214 to rotate. The first threaded sleeve 213 threadedly connected to the one-way screw 214 will move in the opposite direction along the one-way screw 214. When the steel casting needs to be clamped, the two first threaded sleeves 213 need to be brought close to each other. After the two mounting platforms 21 are completely entered into the steel casting, the second motor 215 can be stopped to ensure that the two mounting platforms 21 can extend out of other structures in the steel casting, and the outer edge of the steel casting is as close to the central platform 212 as possible.

[0036] Next, the position of the steel casting needs to be fixed, and the first motor 28 is driven to make the first motor 28 drive the driving gear 27 to rotate. The driving gear 27 is meshed with the driven gear 26, which will drive the driven gear 26 to rotate. Since the driven gear 26 is fixedly connected to the driving gear 25, the driving gear 25 will also rotate in the same direction as the driven gear 26. The driving gear 25 is meshed with the toothed plate 24, so it will drive the toothed plate 24 to move, and the direction of the first motor 28 is controlled, so that the top block 23 connected to the toothed plate 24 is rotated. The first motor 28 can be stopped only after the mounting platform 21 is extended and the roller 29 on the top block 23 contacts the inner wall of the steel casting. When the roller 29 is close to the inner wall of the steel casting, the three top blocks 23 on the mounting platform 21 are extended at the same distance at the same time, so that the steel casting can be adjusted to a position that is concentric with the mounting platform 21, thereby adjusting the position of the steel casting to a position that is on the same straight line as the mounting platform 21, and the steel casting can be rotated by the internal roller 29, so as to facilitate the subsequent rotation and replacement of the surface to be cleaned.

[0037] Example 2

[0038] Reference Figure 1-6, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the sandblasting structure includes a connecting rod 31 fixedly connected to one side of the top block 23, the connecting rod 31 is connected to the top block 23 on the uppermost side of the mounting platform 21, and a driving roller 32 rotatably connected to the connecting rod 31. The driving roller 32 is electrically driven and can rotate autonomously after power is turned on. The roller surface of the driving roller 32 and the roller 29 on the top block 23 are on the same plane, so when the driving roller 32 rotates, it will drive the steel casting to rotate, and the steel casting can rotate through the closely attached roller 29, so that the steel casting can rotate continuously during the sandblasting process. A connecting frame 33 rotatably connected to one side of the driving roller 32 is a T-shaped frame, the upper end of which is used to rotatably connect the driving roller 32, and the lower end of which is used to fixedly connect the limit block 34, and the fixed connection The limit block 34 on the connecting frame 33 and the limit groove 35 on the mounting platform 21 are used together to limit the moving direction of the active roller 32, and the active roller 32 is fixedly connected to the top block 23 through the connecting rod 31, so when the rotating roller 29 on the top block 23 is close to the inner wall of the cast steel part, the active roller 32 will also move the same distance and close to the inner wall of the cast steel part. The limit ring 36 is fixedly connected to the central platform 212, and the limit ring 36 is on the symmetrical side of the first threaded sleeve 213, and there is no thread on the inner side of the limit ring 36. The inner diameter of the limit ring 36 is larger than the reciprocating screw 37, so the limit ring 36 can move on the reciprocating screw 37 without contacting the reciprocating screw 37. In addition, the limit ring 36 is used to block the moving second threaded sleeve 39, thereby changing its movement direction.

[0039] A reciprocating screw 37 is arranged on the inner side of the limiting ring 36, and a third motor 38 is arranged on one side of the reciprocating screw 37. One end of the reciprocating screw 37 is also rotatably connected and connected to the support plate 1 through the connecting end 11, and the other end is connected through the third motor 38 and fixed to the support plate 1 on the other side through the motor seat 12. A second threaded sleeve 39 is arranged on the reciprocating screw 37, and the second threaded sleeve 39 can change its movement direction by blocking the limiting ring 36 to realize reciprocating motion.

[0040] The second threaded sleeve 39 is fixedly connected with a spray gun 310, which can be externally connected to a gravel filling device and can spray gravel. The second threaded sleeve 39 is fixedly connected with a limiting circular sleeve 311, which is fixed on the other side of the second threaded sleeve 39. A limiting rod 312 is arranged on the inner side of the limiting circular sleeve 311, which is fixed between the two support plates 1. The limiting circular sleeve 311 is slidably connected to the limiting rod 312, which can ensure that the second threaded sleeve 39 moves on the reciprocating screw 37.

[0041] During use, when the mounting platform 21 enters the steel casting and extends the top block 23, and the roller 29 on the top block 23 is in close contact with the inner wall of the steel casting, the sandblasting structure can be operated. When the roller 29 is in close contact with the inner wall of the steel casting, the active roller 32 fixedly connected to the top block 23 through the connecting rod 31 will also be in close contact with the inner wall of the steel casting. In this process, the limit block 34 on the connecting frame 33 connected to the active roller 32 always remains in the limit groove 35, so that the active roller 32 moves in the same direction as the top block 23, and then the active roller 32 is driven. The active roller 32 will rotate with the steel casting, and the steel casting can also be rotated while maintaining the supported and limited state through the roller 29 on the top block 23, so that the steel casting can be rotated when it is limited, so that the surface to be processed is fully displayed;

[0042] Because the movement of the central platform 212 sends the mounting platform 21 into the interior of the steel casting, the movement of the limit ring 36 fixed therein moves to the same position as the first threaded sleeve 213, thereby limiting the range of the reciprocating screw rod 37 and enabling the second threaded sleeve 39 to reciprocate within the range clamped by the two limit rings 36. At this time, the range clamped by the limit ring 36 is exactly equal to the length of the steel casting, so that the processing range of the spray gun 310 completely covers the surface of the steel casting, and at this time, the steel casting also has the rotation given by the active roller 32, so when the active roller 32 is driven, the third motor 38 can be driven to drive the reciprocating screw rod 37 to rotate, and the spray gun 310 can be driven to sandblast at the same time. When the reciprocating screw rod 37 drives the second threaded sleeve 39 to reciprocate, it also drives the spray gun 310 to reciprocate, and continuously sandblasts and hits the rotating steel casting, thereby completely cleaning the surface impurities of the steel casting.

[0043] The remaining structures are the same as those of Example 1.
