DETAILED DESCRIPTION

[0016] The following will be described in detail in combination with the accompanying drawings Figs. 1-3 The application will be further described in detail.

[0017] The application embodiment discloses a sandblasting clamping fixture for a sandblasting room. Figs. 1-3 A sandblasting clamping fixture for a sandblasting room, comprising a ground level car 1, a rotating platform 2, a rotating clamping assembly 3 and a power equipment 4;

[0018] The ground level car 1 is the bearing basis of the whole clamp, and provides a stable platform for the installation and operation of other components. A plurality of lifting cylinders 201 are arranged on the ground level car 1 and connected with the support plate 202 of the rotating platform 2. The lifting cylinders 201 adopt the principle of hydraulic drive and can accurately control the movement of the support plate 202 along the Z-axis direction. This connection mode can drive the support plate 202 to rise and fall through the lifting cylinders 201 before use, accurately adjust the height of the rotating table 203 according to the height requirement of the workpiece to be processed, and ensure that the workpiece to be processed is aligned with the central axis of the clamping unit 304, thereby laying a good foundation for subsequent clamping and sandblasting operations and effectively improving the accuracy and efficiency of the operation. The power equipment 4 is also installed on the ground level car 1. The power equipment 4 is in transmission connection with the input shaft of the rotating table 203, such as through belt transmission, chain transmission or gear transmission, so as to stably transmit power to the rotating table 203. During the sandblasting process, the rotating table 203 can be driven to rotate, the workpiece can be horizontally rotated and changed, the surfaces of the workpiece in the horizontal direction can be uniformly covered by the sandblasting gun, the sandblasting dead angle can be avoided, and the quality and integrity of the sandblasting treatment can be improved.

[0019] With reference to Fig. 2 The support plate 202 in the rotating platform 2 not only supports the rotating table 203, but also realizes the height adjustment function through the fixed connection with the lifting cylinder 201. A plurality of ball bearings 5 are arranged on the support plate 202 and in rolling connection with the rotating table 203. The ball bearings 5 can effectively reduce the friction when the rotating table 203 rotates, so that the rotating table 203 rotates more smoothly and flexibly, reduces energy loss and component wear, prolongs the service life of the equipment, and also helps to improve the accuracy of the rotating table 203 rotation, ensures the stability and accuracy of the workpiece during horizontal rotation, and provides protection for accurate sandblasting.

[0020] With reference to Fig. 3The rotating clamping assembly 3 is used for accurately clamping the workpiece and realizing vertical rotation conversion. The translation unit 301 at the lower end of the support 302 is composed of a guide rail 3011 mounted on the ground vehicle 1 and an electric sliding table 3012. The guide rail 3011 provides accurate movement guidance for the electric sliding table 3012, and the electric sliding table 3012 realizes stable movement of the support 302 along the rotating table 203 by motor driving. Through this connection and driving mode, after adjusting the height of the rotating table 203, the electric sliding table 3012 in the translation unit 301 can be moved on the guide rail 3011 to accurately drive the support 302 to move radially along the rotating table 203, so that the clamping units 304 on both sides can accurately approach and clamp the workpiece, ensuring the stability and reliability of clamping. The transmission shaft 3041 in the clamping unit 304 is rotatably arranged on the ground vehicle 1, one end of which is connected to the driving motor 303, and the driving motor 303 provides rotary power for the transmission shaft 3041. The clamping plate 3042 on the transmission shaft 3041 is directly in contact with the workpiece. After clamping the workpiece, the driving motor 303 drives the transmission shaft 3041 to rotate, which can realize the vertical rotation conversion of the workpiece, so that each surface of the workpiece in the vertical direction can also be fully exposed under the sandblasting gun. Combined with the horizontal rotation conversion function of the rotating table 203, the workpiece can be fully and evenly subjected to sandblasting treatment, greatly improving the comprehensiveness and uniformity of the sandblasting operation.

[0021] The implementation principle of the sandblasting clamping fixture for the sandblasting house is as follows: before the sandblasting operation, the workpiece is first carried to the vicinity of the ground vehicle 1. The lifting cylinder 201 is started, and the height position of the support plate 202 is adjusted according to the height and shape of the workpiece, so that the rotating table 203 is at an appropriate height for subsequent clamping and processing of the workpiece. The hydraulic power system of the lifting cylinder 201 provides stable lifting force to ensure that the support plate 202 is stable during lifting without shaking. The stroke can be designed and adjusted according to actual needs to adapt to workpieces of different sizes.

[0022] When the height of the rotating table 203 is adjusted, the electric sliding table 3012 of the translation unit 301 is started. The electric sliding table 3012 moves on the guide rail 3011 according to the preset speed and direction, and drives the support 302 to approach or move away from the workpiece along the rotating table 203. The movement accuracy of the support 302 is jointly ensured by the control system of the electric sliding table 3012 and the accuracy of the guide rail 3011, which can accurately position the clamping unit 304 to the two sides of the workpiece.

[0023] When the support 302 moves to the appropriate position, the driving motor 303 starts to drive the transmission shaft 3041 to rotate, so that the clamping plate 3042 clamps the workpiece. The shape and material of the clamping plate 3042 can be selected according to the shape and surface characteristics of the workpiece. For example, for a circular workpiece, an arc-shaped clamping plate can be used. For a workpiece with a surface prone to damage, soft protective material can be added to the surface of the clamping plate to ensure that the workpiece can be firmly fixed during clamping without damaging the surface of the workpiece.

[0024] After the workpiece is clamped and fixed, the sandblasting operation begins. The power equipment 4 drives the rotating table 203 to rotate, so that the workpiece rotates in the horizontal direction. At the same time, the driving motor 303 can drive the transmission shaft 3041 to rotate as needed to realize the rotation of the workpiece in the vertical direction. Through the coordinated rotation in the horizontal and vertical directions, the sandblasting gun can perform sandblasting treatment on the workpiece from different angles to ensure that each surface and corner of the workpiece can be uniformly sandblasted, effectively avoiding the occurrence of sandblasting dead angles and improving the surface treatment quality of the workpiece and the efficiency of the sandblasting process.

[0025] During the entire sandblasting process, the ground level car 1 can move in the sandblasting room as needed to adjust the relative position of the workpiece and the sandblasting gun, further expand the coverage of sandblasting, and improve the flexibility and comprehensiveness of the sandblasting operation.
