Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, in particular to a grasping mechanism for a car part accumulation chain conveying device. Background Art

[0002] The accumulation chain conveyor is an efficient logistics conveying device. It mainly drives the chain plate to move forward through the rotation of the chain, so as to realize the conveying of items. The accumulation chain conveyor is generally used in logistics transportation. For example, when manufacturing automobiles, parts can be conveyed to each production line.

[0003] The existing accumulation chain conveying equipment generally sets up a load-carrying bracket and directly places the parts on the load-carrying bracket for transportation. However, the load-carrying bracket occupies a large area and has low practicability. If steel cables are used to lift and convey the parts, the parts are prone to swing, with poor stability and easy to cause safety accidents. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a grasping mechanism for a car part accumulation chain conveying device.

[0005] An embodiment of the utility model provides a grasping mechanism for a car part accumulation chain conveying device, including:

[0006] A support frame, on which a conveying device body is installed. A sliding plate is installed on the conveying device body. Four fixing rods are fixedly connected to the sliding plate. Lifting grooves are opened on all four fixing rods. Lifting rods slide in all four lifting grooves. A lifting assembly is installed on the sliding plate. The four lifting rods correspond one by one. A support plate is fixedly connected to each pair of the lifting rods.

[0007] A grasping assembly; the grasping assembly includes two clamping assemblies respectively installed on two support plates. A transmission assembly is installed on the two support plates. The transmission assembly is installed on the two clamping assemblies. The clamping assembly includes a rotation groove opened on the support plate. Two rotating rods are rotatably connected to the inner wall of the rotation groove. Worms are fixedly connected to both of the two rotating rods. First rotating plates are fixedly connected to both of the two rotating rods. Two second rotating plates are rotatably connected to the inner wall of the rotation groove. The two first rotating plates and the two second rotating plates correspond one by one. A clamping plate is jointly installed on each pair of the first rotating plate and the second rotating plate. The two first rotating plates and the two second rotating plates are respectively rotatably connected to the two clamping plates. A worm is rotatably connected to the support plate. The worm is matched with the two worms. The transmission assembly is installed on the two worms.

[0008] Further, the transmission assembly includes a connecting plate fixedly connected to the two support plates. A rotating machine is fixedly connected to the upper end surface of the connecting plate. Two transmission rollers are rotatably connected to the connecting plate. The two transmission rollers respectively penetrate through the two support plates rotatably. The two transmission rollers are respectively fixedly connected to two worm gears. First sprockets are fixedly connected to both of the two transmission rollers. The two first sprockets are driven by a first chain. The output end of the rotating machine penetrates through the connecting plate rotatably and is fixedly connected to one of the transmission rollers.

[0009] Further, the lifting assembly includes a rotating cavity formed in the sliding plate. Four threaded rods are rotatably connected to one inner wall of the rotating cavity. The four threaded rods penetrate through the sliding plate rotatably. The four threaded rods respectively penetrate through four fixed rods. The four threaded rods are respectively threadedly connected to four lifting rods. Second sprockets are fixedly connected to all of the four threaded rods.

[0012] Further, the conveying device body includes a conveyor track, a traction chain, and a driving device.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When grasping work needs to be carried out, the rotating machine starts to work, causing the worm gear to rotate. The worm gear drives the worm wheel to rotate, causing the two first rotating plates to rotate in the rotating slots. The first rotating plates will rotate on the clamping plates, and the clamping plates will also be subjected to the acting force of the first rotating plates, causing the clamping plates to move. When the clamping plates move, they will apply an acting force to the second rotating plates, causing the second rotating plates to rotate in the rotating slots, making the two clamping plates approach each other, realizing the clamping and fixing of the parts. The clamping is more stable, facilitating the conveying device body to transport the parts.

[0015] 2. When the servo motor starts to work, the threaded rods rotate, causing the lifting rods to slide in the fixed rods, realizing the lifting work of the clamping plates, facilitating the user to adjust the height of the clamping plates, improving the practicability of the device, and the lifting process is more stable, avoiding the parts from falling during the lifting process.
