[0013] Figure 2 The utility model discloses a structural schematic diagram of device. CONCRETE EMBODIMENT
[0014] The utility model discloses a clamping mechanism, the mechanism of the utility model is more suitable for being applied to the clamping of small -size product, to avoid its falling from the fixture in the processing or moving process.
[0015] The clamping mechanism is composed of clamping assembly and pulling assembly, and the pulling assembly is placed at the rear end of the clamping assembly.
[0016] The clamping assembly includes a bottom plate 1, a sliding block 3 placed on the bottom plate 1, and a flip plate 31 pivotally connected to the front end of the sliding block 3. The bottom plate 1 is provided with a sliding rail 5, and the sliding block 3 is placed on the sliding rail 5. The sliding block 3 moves to drive the flip plate 31 to reciprocate in the setting direction of the sliding rail 5. In this embodiment, the bottom plate 1 is L-shaped, the sliding block 3 is provided with connecting rods on both sides, springs are sleeved on the connecting rods, the distal end of the connecting rod penetrates through the bottom plate 1 and is connected with a pull rod 2 placed on the thickness of the bottom plate, a pull block 21 is arranged at the upper end of the pull rod 2, and the cylinder drives the sliding block by pulling the pull block 21.
[0017] The distal end 11 of the bottom plate is provided with a profiling groove 13 for placing products, and one side of the profiling groove 13 is provided with a clamping groove 12. The front end of the flip plate 31 is provided with an opening, which can be set according to the specific needs of the product, such as the size of the opening to facilitate the position of the product processing, or a certain space of the slot according to the structure of the product.
[0018] The far end bottom of the flip cover plate 31 is provided with a pressing strip 34 matched with the clamping groove 12, that is, the locking between the far end of the flip cover plate 31 and the far end 11 of the bottom plate is realized through the cooperation of the pressing strip 34 and the clamping groove 12.
[0019] The rear end of the flip cover plate 31 is pivotally connected with the front end of the sliding block 3, the front side of the sliding rail 5 is provided with a connecting plate 6, the front end of the flip cover plate 31 is arranged on the connecting plate 6, and the middle part of the flip cover plate 31 is connected with the connecting plate through a connecting shaft 32, both ends of the connecting shaft 32 are pivotally connected with the flip cover plate 31 and the connecting plate 6 respectively. When the flip cover plate 31 moves under the pulling of the pull rod, the opening and closing action of the flip cover plate 31 will be carried out through the pivoting of the flip cover plate 31.
[0020] In combination Figure 2 The utility model also proposes a device including the above-mentioned clamping mechanism, including a rotating disc 7 and a center plate 8 placed on the rotating disc, the center plate 8 is higher than the rotating disc and is in a arranged state. The rotating disc 7 is circumferentially distributed with clamping assemblies, the center plate 8 is circumferentially distributed with pulling assemblies, and the bottom of the rotating disc 7 is provided with a driving mechanism for driving the rotating disc 7 to rotate. When the device is actually applied, it can be used as an automatic multi-station rotating disc device, that is, the clamping assemblies are arranged at different stations, and the pulling assemblies are arranged at the required stations as needed. When the rotating disc rotates, the center plate remains stationary, and the cylinder 4 in the pulling assembly is in the initial state of the cylinder shaft extending out. When pulling is needed, the cylinder shaft retracts, thereby pulling the pull rod in the clamping assembly to open the clamping assembly, so as to cooperate with other external devices to place or clamp the product. Since there is a height difference between the cylinder shaft in the extended state and the clamping assembly, and the pull rod and the far end of the cylinder shaft are staggered, the extended state of the cylinder shaft will not interfere with the clamping assembly when the rotating disc rotates.
