TECHNICAL FIELD

[0001] The utility model relates to the field of workpiece sand blasting, especially to a sand blasting workpiece clamping device. BACKGROUND

[0002] Sand blasting is a process of cleaning and roughening the surface of the substrate by using the impact of high-speed sand flow. Sand blasting can be roughly divided into dry sand blasting treatment and wet sand blasting treatment. Sand blasting uses compressed air as power to form a high-speed jet beam to spray the workpiece surface with materials (copper sand, quartz sand, silicon carbide, iron sand, Hainan sand) at high speed, so that the appearance or shape of the workpiece surface changes. Due to the impact and cutting action of the abrasive on the workpiece surface, the surface of the workpiece obtains a certain cleanliness and different roughness, and the mechanical properties of the workpiece surface are improved, thus improving the fatigue resistance of the workpiece, increasing the adhesion between the workpiece and the coating, prolonging the durability of the coating, and being beneficial to the leveling and decoration of the coating.

[0003] During the sand blasting process, the clamping of the workpiece is crucial. The traditional clamping method often has problems such as insecure clamping, easy falling off, and difficult adjustment, which not only affects the quality of sand blasting, but also increases the labor intensity and safety risk of the operator.

[0023] In order to better understand the purpose, structure and function of the utility model, the specific embodiments of the utility model "a sandblasting workpiece clamping device" are described in further detail below in conjunction with the drawings.

[0024] Referring to Figures 1-3 In the embodiment, the clamping device comprises a support base 100 and a clamping seat 200, the clamping seat 200 is arranged above the support base 100 through a support arm 101; a driver 201 and a clamping assembly 202 are arranged on the clamping seat 200, the driver 201 is preferably a pneumatic cylinder or a servo motor; the movable end of the driver 201 is connected with the clamping assembly 202 to drive the clamping assembly 202 to clamp and fix the workpiece on the support base 100. In use, the operator places the workpiece on the support base 100, then the driver 201 controls the clamping assembly 202 to clamp the workpiece, and after the clamping and positioning of the workpiece are completed, the sandblasting operation is carried out. Since the support base 100 supports the workpiece, the workpiece is not easy to fall off after being clamped by the clamping assembly 202, the driver 201 drives the clamping assembly 202 to move, so that the clamping of the workpiece can be conveniently and quickly adjusted, and the opening and closing size of the clamping assembly 202 is controllable, so that the clamping assembly 202 can be suitable for clamping workpieces of different sizes.

[0025] Further referring to Figure 2 and Figure 3In the embodiment, the clamping assembly 202 comprises a driving clamping arm 2021 and a driven clamping arm 2022, the driving clamping arm 2021 is fixedly connected with a driving rack 2023, the driving rack 2023 is slidably arranged through the driven clamping arm 2022 and supports the driven clamping arm 2022, the driven clamping arm 2022 is fixedly connected with a driven rack 2024, the driven rack 2024 is slidably arranged through the driving clamping arm 2021 and supports the driving clamping arm 2021, the driving rack 2023 is parallel to the driven rack 2024, the driving clamping arm 2021, the driven clamping arm 2022, the driving rack 2023 and the driven rack 2024 form a “mouth” shape surrounding structure and support each other. The clamping seat 200 is provided with a rotating gear 203, the rotating gear 203 is connected with the driving rack 2023 and the driven rack 2024, and the driving clamping arm 2021 is fixedly connected with the driving end of the driver 201. The driving end of the driver 201 moves left and right to drive the driving clamping arm 2021 to move left and right, and through the linkage of the driving rack 2023, the rotating gear 203 and the driven rack 2024, the driven clamping arm 2022 is driven to move left and right to complete the opening and closing action of the driving clamping arm 2021 and the driven clamping arm 2022. Due to the linkage of the driving rack 2023, the driven rack 2024 and the rotating gear 203, when the driving clamping arm 2021 moves left, the driven clamping arm 2022 will move right at the same time, and the two move towards each other to complete the clamping action faster. The driver 201 only needs to drive the driving clamping arm 2021 to move half the stroke to complete the clamping action, which is fast and energy-saving.

[0026] More specifically, in the embodiment, the driver 201 is arranged at the upper end of the clamping seat 200, the clamping assembly 202 is arranged at the lower end of the clamping seat 200, the clamping seat 200 is provided with a sliding groove 204 penetrating the upper and lower ends of the clamping seat 200, and the upper end of the driving clamping arm 2021 is fixedly connected with the driving end of the driver 201 through the sliding groove 204. Therefore, the driver 201 can drive the driving clamping arm 2021 to move left and right along the sliding groove 204 to ensure the stability of the clamping process and the firmness of the clamped workpiece.

[0027] Further, in the embodiment, the driving clamping arm 2021 and the driven clamping arm 2022 each comprise a chuck 2025, and the inner side of the chuck 2025 is provided with a rubber pad. When the chuck 2025 clamps the workpiece, it can not only prevent scratching the surface of the workpiece, but also increase the friction to clamp the workpiece more firmly.

[0028] Further, in some embodiments, in order to increase the use range of the clamping device, the supporting arm 101 is arranged to be telescopic to adjust the height of the clamping seat 200, thereby being suitable for clamping workpieces of different heights.

[0029] FurtherFigure 3 In the embodiment, the supporting base 100 is fixedly connected to the two sides of the clamping seat 200 through two supporting arms 101; the supporting base 100 comprises a hollow bottom shell 102, a supporting plate 103 is detachably fixed on the bottom shell 102, and a leakage groove 104 is arranged on the supporting plate 103, so that when the surface of the workpiece is subjected to sand blasting treatment, the sand that slides off can enter the hollow space in the bottom shell 102 through the leakage groove 104 and cannot deposit on the surface of the supporting plate 103 to affect the subsequent sand blasting operation; when the sand in the hollow space accumulates to a certain degree, the supporting plate 103 can be detached from the bottom shell 102, and the sand in the interior is cleaned and recycled.

[0030] Further referring to Figure 4 It is another embodiment of the supporting base 100, in the embodiment, the supporting base 200 is fixedly connected with the clamping seat 200 through four reinforced supporting arms 101, and a baffle 105 is arranged on the periphery of the supporting plate 103, so that the workpiece is prevented from sliding out of the supporting plate 103 and being damaged during clamping, and a foot pad 106 is arranged at the bottom of the supporting base 100, so that the stability of the whole device is improved, and the device will not shake during clamping.
