Description

Technical Field

[0001] The invention relates to the technical field of synchronous belt linear slides, in particular to a precisely clamped high-precision synchronous belt linear slide. Background Art

[0002] Synchronous belt slide is a common industrial automation equipment. In the context of the development of industrial automation, the traditional way of moving objects by manual operation or simple mechanical transmission has low efficiency and poor precision. With the advancement of motor technology and control technology, synchronous belt slide came into being. The synchronous belt itself has belt teeth that can precisely mesh with the tooth grooves of the pulley, ensuring precise displacement synchronization during the transmission process. Compared with traditional flat belt transmission, the transmission accuracy is higher. The existing high-precision synchronous belt linear slide has the following technical problems when in use, such as: 1. The existing high-precision synchronous belt linear slide cannot ensure the stability of clamping when in use. This is because the existing clamping structure is relatively simple and can stably clamp workpieces with regular shapes, but common workpieces are not all regular in shape. For workpieces with irregular shapes, the existing clamping cannot effectively clamp them. In addition, even after the existing clamping mechanism is clamped for workpieces with regular shapes, the angle of the workpiece cannot be adjusted, which makes it impossible to adjust it to a suitable angle according to the processing conditions when processing the workpiece; 2. The existing high-precision synchronous belt linear slide is not provided with a structure to resist inertia when in use. Since the high-precision synchronous belt linear slide is in use at a high speed, when it stops suddenly, the workpiece may loosen the clamping structure due to its inertia, resulting in the workpiece clamped on it becoming loose as the high-precision synchronous belt linear slide runs, which is not conducive to stable workpiece processing; Therefore, a high-precision synchronous belt linear slide with precise clamping is needed to solve the above problems.

The main air hose can be used to transport gas to the gas distribution pipe through the air pump, and the gas entering the gas distribution pipe finally enters the closed structure of the semi-closed slideway, thereby pushing the piston rod to move. The movement of the piston rod can achieve the purpose of driving the slider to move. During the movement of the slider, the clamping block can be driven to move synchronously. The clamping block can rotate on the slider, so that the irregular workpiece can be effectively clamped and fixed by the rotation of multiple clamping blocks; 2. Through the structure of the worm gear and the worm, the purpose of rotating the support table can be achieved, and then the angle of the workpiece after clamping can be adjusted as needed, which is helpful for processing the workpiece; 3. When the synchronous belt linear slide temporarily stops moving the workpiece, the workpiece generates inertia due to the sudden stop, which will react on the clamping block. At this time, the clamped workpiece may become loose, and in this process, the gravity ball will also hit the corresponding piston rod 2 due to inertia, causing the piston rod 2 to squeeze the gas in the piston tube, allowing the gas in the piston tube to pass through the bronchial hose, thereby increasing the air pressure in the main air hose. When the workpiece suddenly stops moving, the strength of the clamping block clamping the workpiece can be increased, thereby preventing the workpiece from loosening, thereby ensuring the accuracy of clamping and avoiding defects in the processed workpiece due to loosening or even the appearance of defective products.

The structural shape of the clamping block 15 is D-shaped, which is used to clamp and fix workpieces of different shapes.

[0019] Embodiment 2: In order to solve the problem that the previous high-precision synchronous belt linear slide is not provided with a structure to resist the inertia of the workpiece, which easily causes the clamped workpiece to loosen when it stops suddenly, the following technical solution is provided, specifically, an anti-loosening mechanism is provided on the side of the upper sliding block 8.

During the use of the high-precision synchronous belt linear slide, the workpiece can stop moving at any time as needed. At this time, the workpiece will generate an outward thrust on the clamping block 15 due to inertia. At the same time, the gravity ball 22 will also impact the corresponding piston rod 23 due to inertia, so that the impacted piston rod 23 has a tendency to move in the piston tube 21, so that the gas in the piston tube 21 has a tendency to be transported to the main gas hose 28 through the bronchial hose 27, thereby increasing the air pressure in the main gas hose 28, which helps to increase the degree of clamping of the workpiece by the clamping block 15, and is beneficial to resisting the inertia of the workpiece, thereby ensuring that the workpiece is effectively, stably and accurately clamped. The diameter of the gravity ball 22 is smaller than the inner diameter of the piston tube 21, and the piston tube 21 is arranged horizontally, so that the gravity ball 22 can roll in the piston tube 21, and the bronchial hose 27 is Y-shaped, which is convenient for the bronchial hose 27 to connect the two ends of the piston tube 21 connected to it with the main gas hose 28.
