Description

Technical Field

[0001] This utility model relates to the field of sandblasting technology, and in particular to a rotary positioning device for sandblasting workpieces. Background Technology

[0002] In industrial production, sandblasting is a commonly used surface treatment process, widely applied in workpiece surface cleaning, roughening, and finishing. It effectively removes impurities such as rust, oil, and scale from workpiece surfaces, improving adhesion and aesthetics. However, existing workpiece sandblasting devices have many problems in practical use, so a rotary positioning device for workpiece sandblasting is designed.

[0003] Traditional devices struggle to allow the sandblasting head to move flexibly in three-dimensional space. Most can only adjust the displacement in a single direction or within a limited range. Operators need to manually adjust the head repeatedly, which not only consumes a lot of time and energy, but also makes it difficult to avoid errors caused by manual operation. This results in the sandblasting head not being able to accurately align with different parts of the workpiece, making it difficult to meet the sandblasting requirements of complex-shaped workpieces. Consequently, the sandblasting operation has low precision and limited coverage, making it difficult to guarantee the consistency and stability of sandblasting quality. Utility Model Content

[0004] This disclosure relates to a rotary positioning device for sandblasting workpieces, in order to solve the technical problems mentioned in the background art.

[0005] In a first aspect, this disclosure provides a rotary positioning device for sandblasting workpieces, specifically comprising: a sandblasting chamber; a connecting pipe connected to the rear end of the sandblasting chamber, an axial flow fan connected to the lower end of the connecting pipe, a dust collector connected to the outlet of the axial flow fan, two supports installed inside the sandblasting chamber, a first sliding seat that can slide left and right installed on the upper end of each of the two supports, and a first toothed plate installed on the upper end of each of the two supports, a first motor installed on each of the two first sliding seats, a gear that can mesh with the first toothed plate installed on the output shaft of the first motor, a crossbeam installed between the two first sliding seats, a second sliding seat that can slide back and forth installed on the crossbeam, a lifting column that can slide up and down sliding on the second sliding seat, and a robotic arm for mounting a sandblasting head installed at the lower end of the lifting column.

[0006] In at least some embodiments, a second motor and a third motor are mounted on the second sliding seat, and a second toothed plate and a third toothed plate are mounted on the crossbeam and the lifting column, respectively.

[0007] In at least some embodiments, the output shafts of the second motor and the third motor are respectively equipped with gears that can mesh with the second gear plate and the third gear plate.

[0008] In at least some embodiments, a slide rail is installed inside the sandblasting chamber, a movable seat that can move left and right slides on the slide rail, a fourth motor is installed on the slide rail, a pulley is installed on the output shaft of the fourth motor, a waist-shaped groove is provided on the slide rail, a pulley is installed in the waist-shaped groove, and a transmission belt is connected between the two pulleys.

[0009] In at least some embodiments, the transmission belt is fixedly connected to the lower end of the movable seat, a partition is installed at the upper end of the movable seat, a rotating column is installed on the partition via a bearing, and a gear is fixed on the rotating column.

[0010] In at least some embodiments, a slider slides on the partition, and a fourth toothed plate is mounted on the slider, which meshes with a gear on the rotating column.

[0011] In at least some embodiments, the upper end of the rotating column is fixed with a placement plate for placing workpieces, a hydraulic rod is installed on the partition plate, and the piston rod of the hydraulic rod is connected to the slider.

[0012] This utility model provides a rotary positioning device for workpiece sandblasting, which has the following beneficial effects:

[0013] In this invention, the first motor drives the gear to mesh with the first toothed plate, enabling the first sliding seat to slide left and right on the bracket. The second motor and the third motor respectively drive the gear to cooperate with the second toothed plate and the third toothed plate, enabling the second sliding seat to slide back and forth on the crossbeam and the lifting column to slide up and down. This allows the sandblasting head installed on the lower end of the lifting column robotic arm to move flexibly in three-dimensional space, accurately adjust the sandblasting position, meet the sandblasting requirements of workpieces of different shapes and locations, and effectively improve the accuracy and coverage of sandblasting operations.

[0014] Furthermore, in this invention, the fourth motor drives the pulley to rotate, and through the transmission belt, the moving seat moves left and right on the slide rail. In conjunction with the hydraulic rod, the slider is pushed, which drives the fourth toothed plate that meshes with the gear on the rotating column to move, thereby realizing the rotation of the rotating column and the placement plate. This allows the workpiece placed on the placement plate to rotate at multiple angles, ensuring that all surfaces of the workpiece can be uniformly sandblasted, thus improving the sandblasting quality and effect.

[0015] Furthermore, in this invention, the connecting pipe at the rear end of the sandblasting chamber, the axial flow fan, and the dust collection tank form a dust removal system. During the sandblasting process, the axial flow fan draws the dust generated in the sandblasting chamber into the dust collection tank through the connecting pipe, effectively purifying the working environment, reducing the harm of dust to the health of operators, and meeting the requirements of environmentally friendly production, thereby reducing the pollution of the surrounding environment caused by dust emissions.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Please refer to Figures 1 to 8 Example 1:

[0031] This utility model proposes a rotary positioning device for workpiece sandblasting, comprising: a sandblasting chamber 1; a connecting pipe 2 connected to the rear end of the sandblasting chamber 1, an axial flow fan 21 connected to the lower end of the connecting pipe 2, a dust collector 22 connected to the outlet of the axial flow fan 21, two supports 11 installed inside the sandblasting chamber 1, a first sliding seat 12 that can slide left and right installed on the upper end of each of the two supports 11, and a first toothed plate 111 installed on the upper end of each of the two supports 11, a first motor 121 installed on each of the two first sliding seats 12, a gear that can mesh with the first toothed plate 111 installed on the output shaft of the first motor 121, a crossbeam 13 installed between the two first sliding seats 12, a second sliding seat 14 that can slide back and forth installed on the crossbeam 13, a lifting column 15 that can slide up and down sliding on the second sliding seat 14, and a robotic arm 16 for installing a sandblasting head installed at the lower end of the lifting column 15.

[0032] In this embodiment, a second motor 141 and a third motor 142 are mounted on the second sliding seat 14. A second gear plate 131 and a third gear plate 151 are respectively mounted on the crossbeam 13 and the lifting column 15. Gears that can mesh with the second gear plate 131 and the third gear plate 151 are respectively mounted on the output shafts of the second motor 141 and the third motor 142. The function is that the gear on the output shaft of the second motor 141 meshes with the second gear plate 131 on the crossbeam 13. When the second motor 141 starts running, the gear rolls on the second gear plate 131, driving the second sliding seat 14. The seat 14 slides back and forth on the crossbeam 13, thereby adjusting the position of the robotic arm 16 and the sandblasting head installed at the lower end of the lifting column 15. This allows for sandblasting of workpieces at different positions. The gear on the output shaft of the third motor 142 meshes with the third toothed plate 151 on the lifting column 15. When the third motor 142 is working, its gear rolls on the third toothed plate 151, driving the lifting column 15 to slide up and down on the second sliding seat 14. This allows for vertical height adjustment of the sandblasting head, meeting the needs of sandblasting operations on workpieces at different heights or with different dimensions.

[0033] In Example 2, based on Example 1, a slide rail table 17 is installed inside the sandblasting chamber 1. A movable seat 18 that can move left and right slides on the slide rail table 17, and a fourth motor 171 is installed on the slide rail table 17. A pulley is installed on the output shaft of the fourth motor 171. The slide rail table 17 is provided with a waist-shaped groove, and a pulley is installed in the waist-shaped groove. A transmission belt 172 is connected between the two pulleys. The transmission belt 172 is fixedly connected to the lower end of the movable seat 18. A partition 181 is installed on the upper end of the movable seat 18. Its function is: after the fourth motor 171 is started, the output shaft drives the pulley to rotate. Since the two pulleys are connected by the transmission belt 172, and the transmission belt 172 is fixed to the lower end of the movable seat 18, the rotation of the pulley will drive the transmission belt 172 to move, thereby causing the movable seat 18 to slide left and right on the slide rail table 17, realizing the horizontal position adjustment of the workpiece placed on it, so that the sandblasting head can perform sandblasting treatment on different lateral positions of the workpiece.

[0034] In Example 3, based on Examples 1 and 2, a rotating column 182 is mounted on the partition 181 via bearings. A gear is fixed on the rotating column 182. A slider 1811 slides on the partition 181, and a fourth toothed plate 1813 is mounted on the slider 1811. The fourth toothed plate 1813 meshes with the gear on the rotating column 182. A placement plate 183 for placing workpieces is fixed to the upper end of the rotating column 182. A hydraulic rod 1812 is mounted on the partition 181. The piston rod of the hydraulic rod 1812 is connected to the slider 1811. Its function is: the piston of the hydraulic rod 1812... The rod is connected to the slider 1811. When the hydraulic rod 1812 works, the piston rod extends and retracts, causing the slider 1811 to slide on the partition plate 181. The fourth toothed plate 1813 on the slider 1811 meshes with the gear on the rotating column 182. The sliding of the slider 1811 drives the gear to rotate through the fourth toothed plate 1813, which in turn drives the rotating column 182 and the placement plate 183 fixed on its upper end to rotate. The workpiece placed on the placement plate 183 rotates accordingly, so that different parts of the workpiece can face the sandblasting head in turn, realizing multi-angle sandblasting treatment, ensuring uniform sandblasting on the workpiece surface, and improving the sandblasting quality.

[0035] The working principle of this embodiment is as follows: When the horizontal position of the workpiece needs to be adjusted, the fourth motor 171 is started, and its output shaft drives the pulley to rotate. The two pulleys are connected by a transmission belt 172, which is fixed to the lower end of the movable seat 18. The rotation of the pulley drives the transmission belt 172 to move, thereby causing the movable seat 18 to slide left and right on the slide rail 17. The workpiece placed on the partition 181 on the movable seat 18 moves accordingly, realizing the horizontal position adjustment of the workpiece. When the workpiece needs to be rotated, the hydraulic rod 1812 is activated. Its piston rod extends and retracts, causing the slider 1811 to slide on the partition 181. The fourth toothed plate 1813 on the slider 1811 meshes with the gear on the rotating column 182. The sliding of the slider 1811 drives the gear to rotate through the fourth toothed plate 1813, thereby driving the rotating column 182 and the placement plate 183 fixed on its upper end to rotate. The workpiece placed on the placement plate 183 rotates accordingly, realizing multi-angle sandblasting. At the same time, the hydraulic rod 1812 precisely controls the extension and retraction of the piston rod, accurately controlling the position of the workpiece. The sliding distance of the slider 1811 is controlled to precisely control the rotation angle of the rotating column 182. After the workpiece is positioned, the first motor 121 is started, and the gear on its output shaft meshes with the first toothed plate 111, driving the first sliding seat 12 to slide left and right on the bracket 11, thus moving the crossbeam 13. The gear on the output shaft of the second motor 141 meshes with the second toothed plate 131 on the crossbeam 13, driving the second sliding seat 14 to slide back and forth on the crossbeam 13. The gear on the output shaft of the third motor 142 meshes with the third toothed plate 151 on the lifting column 15, driving the lifting column 15 to slide up and down on the second sliding seat 14. Through the cooperation of the three, the position of the sandblasting head on the robotic arm 16 at the lower end of the lifting column 15 is adjusted in three-dimensional space so that it is aligned with the part of the workpiece to be sandblasted. The sandblasting operation begins, and the sandblasting head performs sandblasting treatment on the workpiece. At the same time, the axial flow fan 21 is started, and the dust generated in the sandblasting chamber 1 is sucked into the dust collection tank 22 through the connecting pipe 2 to achieve the dust removal function during the sandblasting process and ensure a clean working environment.
