Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically to a sandblasting system. Background Technology

[0002] In engine manufacturing, sandblasting of the inner surfaces of the cylinder block and cylinder liners is crucial to the quality of subsequent machining. Traditional sandblasting equipment is mainly designed for external surface treatment or simple workpieces, and its tooling and positioning systems are usually fixed, making it difficult to adapt to workpieces with complex and diverse internal cavity structures. In particular, cylinder blocks often contain multiple internal cavities, or multiple cylinder liners with individual internal cavities are placed together to form multiple internal cavities. Traditional equipment cannot sandblast multiple internal cavities simultaneously. Therefore, the production line needs to frequently adjust or change tooling when changing workpieces, resulting in low production efficiency, insufficient flexibility, and problems with operational inconvenience and discontinuous production. Utility Model Content

[0003] The purpose of this invention is to at least solve the problem of how to perform sandblasting operations on multiple internal cavities simultaneously. This purpose is achieved through the following technical solution:

[0004] This utility model proposes a sandblasting system, comprising:

[0006] A movable part is disposed on the main frame and spaced apart from the working position along the height direction. The movable part includes a moving mechanism and a connecting structure. The moving mechanism can drive the connecting structure to move along the height direction and the length direction.

[0007] A sandblasting device, which is connected to the connecting structure.

[0008] According to the sandblasting system of this utility model, the working position of the main frame ensures that the arrangement direction of multiple inner cavities is consistent with the length direction of the equipment. Driven by the moving part, the sandblasting device can move in a coordinated manner along the height and length directions, achieving sandblasting operations on multiple inner cavities. This avoids the repetitive positioning and adjustment time required by traditional sandblasting heads operating one by one, thus significantly shortening the overall sandblasting time of the workpiece, increasing the processing quantity per unit time, and reducing the production cycle. Furthermore, regardless of whether the workpiece to be sandblasted is a single-cavity cylinder liner or a multi-cavity cylinder body, the sandblasting device can adjust its path according to a preset program to achieve effective sandblasting of different numbers and arrangements of inner cavities. By adjusting the movement trajectory of the moving part in the height and length directions, the sandblasting system can adapt to different workpiece sizes and inner cavity positions, completing the operation without replacing major mechanical components, thereby greatly improving the production line's adaptability to product diversity.

[0034] like Figures 1 to 6 As shown, according to an embodiment of the present invention, a sandblasting system 100 is proposed, including a main frame 10, a moving part 20, and a sandblasting device 30. The main frame 10 has a working position for placing a workpiece to be sandblasted. The main frame 10 has a height direction and a length direction, and the length direction is consistent with the arrangement direction of the multiple cavities of the workpiece 200 to be sandblasted. The moving part 20 is disposed on the main frame 10 and spaced apart from the working position along the height direction. The moving part 20 includes a moving mechanism and a connecting structure 222. The moving mechanism can drive the connecting structure 222 to move along the height direction and the length direction. The sandblasting device 30 is connected to the connecting structure 222, and the sandblasting device 30 can move together with the connecting structure 222 along the height direction and the length direction.

[0035] According to the sandblasting system 100 of this embodiment, the working position of the main frame 10 is such that the arrangement direction of multiple inner cavities is consistent with the length direction of the equipment. Driven by the moving part 20, the sandblasting device 30 can move in a coordinated manner along the height and length directions, realizing sandblasting operations on multiple inner cavities. This avoids the repetitive positioning and adjustment time required for traditional sandblasting heads to operate one by one, thus significantly shortening the overall sandblasting time of the workpiece, increasing the processing quantity per unit time, and reducing the production cycle. Furthermore, regardless of whether the workpiece 200 to be sandblasted is a single-cavity cylinder liner or a multi-cavity cylinder body, the sandblasting device 30 can adjust its path according to a preset program to achieve effective sandblasting of different numbers and arrangements of inner cavities. By adjusting the movement trajectory of the moving part 20 in the height and length directions, the sandblasting system 100 can adapt to different workpiece sizes and inner cavity positions, completing the operation without replacing major mechanical components, thereby significantly improving the production line's adaptability to product diversity.

[0036] It is understandable that the height direction is the Z-axis direction and the length direction is the X-axis direction.

[0037] In some embodiments, the number of moving parts 20 is at least two, and the at least two moving parts 20 are spaced apart along the length direction. Each moving part 20 is connected to a sandblasting device 30 via a connecting structure 222. The multiple moving parts 20 are spaced apart along the length direction, so that multiple sandblasting devices 30 can simultaneously perform sandblasting operations on the inner cavities at different positions on the workpiece, avoiding the inefficiency of traditional single sandblasting head operations, thereby greatly improving the overall work efficiency.

[0038] Specifically, taking a six-cylinder engine block as an example, the block contains six internal cavities arranged sequentially along its length, labeled as the first to the sixth internal cavity. The system includes two moving parts 20, spaced apart along the length, with the interval corresponding to the positions of two internal cavities. Each moving part 20 is connected to a sandblasting device 30 via its respective connecting structure 222. The specific sandblasting process is as follows: During initial positioning, the first moving part 20 precisely aligns its connected sandblasting device 30 with the first internal cavity using a preset program, while the second moving part 20 aligns with the fourth internal cavity. In the first cycle of sandblasting, both sandblasting devices 30 are activated simultaneously to sandblast the first and fourth internal cavities respectively, ensuring uniform sandblasting and meeting process requirements. In the second cycle of positioning and sandblasting, after completing the first cycle, both moving parts 20 simultaneously move one internal cavity position along the length. After adjustment, the first moving part 20 aligns the sandblasting device 30 with the second internal cavity, while the second moving part 20 automatically adjusts to align with the fifth internal cavity. The sandblasting operation is initiated, and the second and fifth inner cavities are sandblasted. In the third cycle of positioning and sandblasting, after another simultaneous movement, the two moving parts 20 are aligned with the third and sixth inner cavities respectively, and the sandblasting device 30 is activated to complete the final round of sandblasting. Through the above segmented operation, the sandblasting system 100 achieves continuous and uniform sandblasting treatment of all six inner cavities. Each cycle is completed in parallel by the two moving parts 20, ensuring the continuity and efficiency of the process.

[0039] In some embodiments, the moving mechanism includes a first sliding component and a second sliding component. The first sliding component includes a first slide rail 21 and a support arm 212. The first slide rail 21 is disposed along the length direction of the main frame 10, and the support arm 212 is slidably connected to the first slide rail 21. The second sliding component includes a second slide rail 22, which is connected to the support arm 212 along the height direction. A connecting structure 222 is slidably connected to the second slide rail 22. The first slide rail 21 is arranged along the X-axis and serves as a guide element for the first sliding component, ensuring that the entire sandblasting device 30 can move linearly in the X-axis direction. The support arm 212 is slidably connected to the first slide rail 21, and by sliding along the X-axis on the first slide rail 21, the sandblasting device 30 can be positioned and adjusted in the X-axis direction. The support arm 212 adopts a cantilever design, and its rigidity and stability ensure that it maintains a precise movement trajectory even under load. The second slide rail 22 is disposed along the Z-axis direction and fixed to the side of the support arm 212. The connecting structure 222 is slidably connected to the second slide rail 22, enabling precise positioning and adjustment of the sandblasting device 30 in the vertical direction. Through the second slide rail 22, the sandblasting device 30 can be finely adjusted in the height direction to match the height requirements of different workpiece cavities. The first and second sliding components achieve precise positioning in three-dimensional space through independent movement in the X-axis and Z-axis directions.

[0040] Furthermore, the first sliding assembly also includes a first servo motor 211, which is mounted on the main frame 10 and is connected to the support arm 212 via a ball screw to control the movement of the support arm 212 along the X-axis. The second sliding assembly also includes a second servo motor 221, which is mounted on the support arm 212 and is connected to the connecting structure 222 via a linear guide rail to enable the connecting structure 222 to slide in the Z-axis direction.

[0041] In some embodiments, the sandblasting system 100 further includes a tooling 90, and the main frame 10 further includes a conveying mechanism 40 disposed along its length. The conveying mechanism 40 includes a conveyor belt, which can drive the tooling 90 to move to the working position along the X-axis. Specifically, the transmission mechanism also includes a roller assembly and a fixing mechanism. The roller assembly includes multiple rollers, one end of the transmission belt is a drive roller, the other end is a tension roller, and the middle one is a follower roller. The drive roller is connected to a servo motor or a frequency converter-driven motor, and the motor rotation drives the conveyor belt to move. The tension roller is used to adjust the tension of the conveyor belt to ensure the smoothness of the conveying process. The tooling 90 is fixed to the conveyor belt by tightly engaging with positioning claws or mounting grooves provided on the conveyor belt, thereby moving with the conveyor belt when it moves. In the conveying mechanism 40, the drive roller directly meshes with the conveyor belt. When the motor starts, the drive roller begins to rotate, and its rotational power is transmitted to the conveyor belt through friction or meshing with the conveyor belt, causing the conveyor belt to move continuously along the X-axis. The tooling 90 is fixedly connected to the conveyor belt via a pre-designed positioning device (such as a gripper, bracket, or dedicated fixing groove), ensuring that the tooling 90 will not detach from the conveyor belt due to vibration or displacement. When the conveyor belt moves, the tooling 90 is also synchronously driven, smoothly moving to the next station along the X-axis. Through a precision control system of servo motors and drive rollers, the conveyor belt can move at a constant speed or according to a set step sequence, enabling the tooling 90 to achieve accurate alignment during the coordinated operation of the sandblasting device 30 and the moving part 20, ensuring continuous automated production. The start-up, stopping, and acceleration / deceleration of the conveyor belt are all regulated by the electronic control system, ensuring the entire conveying process is stable and reliable.

[0042] In some embodiments, the tooling 90 includes at least two positioning elements 91 and a tray 92. The tray 92 has multiple positioning structures spaced apart along the X-axis. Each pair of positioning elements 91 can selectively connect to one positioning structure, and the positioning elements 91 and the positioning structures are detachably coupled. The positioning elements 91 are used to fix the inner cavity of the workpiece 200 to be sandblasted. Specifically, a working surface is formed on the tray 92, and the workpiece 200 to be sandblasted is placed on the working surface. The tray 92 has multiple positioning structures (such as positioning holes, slots, or fixing bosses) evenly arranged along the X-axis. These positioning structures are used to provide basic fixed support for the workpiece 200 to be sandblasted at different positions. The spacing of the positioning structures can ensure that each positioning point can be accurately aligned with the inner cavity of the workpiece 200 to be sandblasted, according to the size and arrangement requirements of the inner cavity of the workpiece 200. The positioning elements 91 are fixed to part of the positioning structure of the tray 92 by a detachable connection method (such as a snap-fit, bolt fixing, or magnetic structure). The shape and size of the positioning component 91 are customized according to the specific shape of the workpiece's inner cavity, which can firmly clamp and fix the workpiece to prevent displacement during the sandblasting operation. The detachable design allows the positioning component 91 to be quickly disassembled and reinstalled when the positioning scheme needs to be changed or adjusted, which can easily adapt to the changes in the inner cavity structure and size of different workpieces 200 to be sandblasted.

[0043] Furthermore, the positioning structure includes alternating first positioning holes 921 and second positioning holes 922. The first positioning hole 921 is an X-shaped hole, and the second positioning hole 922 consists of four circular holes arranged in a diamond pattern. The positioning member 91 has protrusions that can be inserted into the first positioning hole and / or the second positioning hole 922. Utilizing the geometric advantages of the X-shaped hole and the diamond-shaped holes, the positioning method can be flexibly selected according to the actual situation of the workpiece, thereby ensuring that the workpiece 200 to be sandblasted maintains a precise and stable position during the sandblasting operation, avoiding uneven sandblasting caused by workpiece movement. Specifically, in the first embodiment, the positioning member 91 is only inserted into the first positioning hole 921. In this embodiment, the positioning member 91 is designed with protrusions that match the X-shaped hole. After the workpiece is placed on the tray 92, the protrusions are inserted into the alternating first positioning holes 921 using the positioning member 91. When positioning the inner cavity of the workpiece, the multi-directional insertion advantage of the X-shaped hole is utilized to achieve fast and flexible positioning. This design is suitable for applications requiring flexible angle adjustment or high positioning accuracy for workpiece fixation. In the second embodiment, the protrusions on the positioning element 91 are designed to match a rhomboid positioning area formed by four circular holes. After the workpiece is placed on the tray 92, the protrusions of the positioning element 91 insert into one or more of the alternately arranged second positioning holes 922 on the tray 92. The workpiece is securely fixed through the rhomboid arrangement of the circular holes, providing balanced and symmetrical support and preventing rotation or displacement of the workpiece during sandblasting. This design is suitable for sandblasting processes requiring high stability. In the third embodiment, the positioning element 91 is designed with multiple protrusions, some of which match the shape of the X-shaped holes, while others match the four rhomboid arrangement of the circular holes. After the sandblasted workpiece 200 is placed on the tray 92, some of the protrusions of the positioning element 91 insert into the first positioning hole 921, while others insert into the second positioning hole 922, thus utilizing the combined advantages of the two positioning structures to achieve a higher precision and stability fixation effect. This design is suitable for applications requiring both high workpiece positioning accuracy and stability.

[0044] In some embodiments, the sandblasting device 30 includes a spray gun 31 and a rotating mechanism 32. The rotating mechanism 32 is drive-connected to the spray gun 31 to rotate the spray gun 31 along its own axis. The rotating mechanism 32 is connected to the connecting structure 222. Specifically, the rotating mechanism 32 and the spray gun 31 are drive-connected via a transmission mechanism (such as a coupling, gear drive, or belt drive), enabling the spray gun 31 to rotate continuously along its own axis. The rotating mechanism 32 is powered by a servo motor, and by controlling and adjusting the rotation speed and angle, it ensures that the spray gun 31 rotates at a constant and adjustable rate during operation.

[0045] Furthermore, the sandblasting system 100 includes a sand storage chamber 50, which is connected to the spray gun 31, and a pneumatic-electric slip ring is provided at the connection between the spray gun 31 and the sand storage chamber 50. The sand storage chamber 50 is connected to the spray gun 31 to continuously supply the abrasive required for sandblasting. To solve the problem of possible kinking or interruption in the transmission of abrasive and control signals during the rotation of the spray gun 31, the sandblasting system 100 provides a pneumatic-electric slip ring at the connection between the spray gun 31 and the sand storage chamber 50. The pneumatic-electric slip ring consists of an outer ring fixed to the side of the sand storage chamber 50 and an inner ring connected to the spray gun 31 and rotating with the spray gun 31. A continuous air passage is preset inside the slip ring to transmit compressed air and abrasive, so that the spray gun 31 can still obtain a stable and continuous abrasive supply when rotating. A dedicated circuit channel is also provided inside the slip ring to transmit the electrical energy and signals required by the spray gun 31, realizing real-time monitoring and control of the spray gun 31. The function of the pneumatic-electric slip ring is to maintain the relative position of the fixed ring and the rotating ring when the spray gun 31 rotates along its own axis, ensuring the continuous connection of the air and electrical channels and avoiding connection breakage or signal interference caused by rotation. The air circuit ensures that the abrasive and compressed air in the sand storage bin 50 are not affected by rotation, and stably supplies the spray gun 31. The electrical circuit ensures that the operating parameters of the spray gun 31 (such as rotation speed, sandblasting pressure, etc.) can be monitored and adjusted in real time, improving the accuracy and stability of the sandblasting process.

[0046] In some embodiments, a sandblasting chamber is formed within the main frame 10, and both the moving part 20 and the sandblasting device 30 are located within the sandblasting chamber. The main frame 10 forms a dedicated sandblasting chamber, creating a closed or semi-closed working area. The moving part 20 and the sandblasting device 30 are both arranged within this sandblasting chamber, achieving a fully enclosed sandblasting process. Specifically, the sandblasting chamber is formed within the main frame 10 by using sealing baffles, doors, and dustproof sealing strips to isolate the sandblasting work area from the external environment.

[0047] Furthermore, the sandblasting system 100 also includes a dust collector 60 and an abrasive recovery device 80. The dust collector 60 is connected to the sandblasting chamber, and the abrasive recovery device 80 is connected to the sandblasting chamber and configured in conjunction with the working position. Specifically, the dust collector 60 is connected to the sandblasting chamber through a sealed pipe or duct to ensure that dust and suspended abrasive particles generated during the sandblasting operation can be quickly drawn into the dust collection system. The dust collector 60 is equipped with a high-efficiency filter (such as a HEPA filter or an electrostatic precipitator) to purify the air during the suction process, effectively removing fine dust and reducing the impact on the working environment and personnel health. In addition, the abrasive recovery device 80 is connected to the sandblasting chamber through a dedicated recovery channel and is usually located below the working position or at the bottom of the sandblasting chamber. The abrasive recovery device 80 has a screening and grading mechanism to separate the recovered abrasive from the dust. Since the working position is fixed and the workpiece 200 is located in the working area inside the sandblasting chamber, the abrasive will fall to the perimeter of the working position due to gravity and airflow during the sandblasting process. The abrasive recovery device 80 can quickly capture the falling abrasive through the arrangement of guide troughs or collection troughs, ensuring that it does not affect subsequent processes and realizing the recycling of abrasive.

[0048] In some embodiments, the sandblasting system 100 also includes an outer casing 101, which completely encloses the main frame 10 and all its internal devices (including tooling 90, sandblasting chamber, moving part 20, sandblasting device 30, dust collector 60, abrasive recovery device 80, etc.) within the casing 101. The casing 101 is equipped with a ventilation system, a dust removal system, and a temperature and humidity control device to ensure smooth airflow circulation, prevent abrasive and dust from escaping, and provide a constant operating environment for the equipment. The lighting and monitoring systems within the casing 101 are also rationally arranged, allowing operators to observe the sandblasting process status and equipment operation in real time through observation windows. The casing 101 not only effectively isolates dust and noise generated during sandblasting but also protects operators from high-speed abrasive splashes and high-temperature spray, improving overall workshop safety. For noise control, sound-insulating materials or structures can be added to the inside of the casing 101 to further reduce the impact of operating noise on the surrounding environment.

[0049] In some embodiments, an electrical control box 70 is also provided inside the outer cover 101. The electrical control box 70 is electrically connected to the first servo motor 211 and the second servo motor 221, etc., to control the sandblasting system 100 to perform sandblasting operations.

[0050] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
