In order to achieve the above purpose, the utility model adopts the following technical scheme: a rubbing and pressing device for a prefabricated cement component comprises a fixing frame and a rubbing and pressing device, wherein the rubbing and pressing device comprises a rotating shaft, a rubbing and pressing seat fixedly connected with the rotating shaft and a driving plate, the rotating shaft is longitudinally and rotatably installed on the fixing frame, the driving plate is fixedly connected with the rotating shaft, the end part of the driving plate is provided with a telescopic device, the other end of the telescopic device is rotatably installed on the fixing frame, and the driving plate drives the rotating shaft to rotate through the extension or retraction of the telescopic device, so that the rubbing and pressing seat rotates; the beneficial effects of this technical scheme lie in: the rotating shaft is directly connected with the fixing frame, and the driving plate is directly connected with the rotating shaft, so that the transmission structure of the rotating shaft is greatly reduced; the telescopic device is used for driving, the size and the structure of the driving device can be greatly reduced, the driving efficiency is greatly improved, the later maintenance cost is greatly reduced, and the failure rate is low.

Preferably, the end part of the driving plate is provided with driving plate shaft seats extending out of the top surface and the bottom surface of the driving plate, the two groups of telescopic devices are arranged, one ends of the two groups of telescopic devices are respectively rotatably arranged at the top end or the bottom end of the driving plate shaft seat, and the other ends of the two groups of telescopic devices are respectively arranged on fixing frames positioned at two sides of the driving plate; the beneficial effects of this technical scheme lie in: through connect telescoping device respectively at drive plate top surface and bottom surface, at first it increases the rotational stability and the atress homogeneity of pivot by a wide margin, increases life and stable effect, and secondly, the structure of two retractions can effectively increase driven continuous operation validity and increase drive power.

Preferably, the end part of the telescopic device is provided with a shaft sleeve which is sleeved on a shaft seat of the driving plate, the fixed frame is provided with a fixed seat, and the fixed seat is rotatably connected with the other end of the telescopic device; this technical scheme has further increased the convenience of later maintenance.

Preferably, the top end and the bottom end of the fixing frame are respectively fixedly provided with a fixing plate, a sleeve is fixedly arranged on the fixing plate, and the rotating shaft is rotatably arranged in the sleeve; this technical scheme has further optimized the connection structure of pivot with the mount, and the structure is further simplified to the steadiness has been increased.

Preferably, a cylinder is fixedly installed at the bottom end of the driving plate, and the rotating shaft is fixedly connected with the rubbing pressing seat through the cylinder; the beneficial effects of this technical scheme lie in: the structure that prior art adopted the pivot directly to be connected with rubbing and pressing the seat more, however, because rub and press in succession and (because the cement prefabricated component size is great need high strength operation) the applied holding down force great, pivot lug connection's scheme has the direct hidden danger that leads to the pivot fracture or rub and press the seat and drop, and this technical scheme is through setting up the cylinder, very big reduction the formation of pivot, has increaseed the area of being connected of pivot and cylinder through the cylinder to the pivot has increased the life who presses the seat with rubbing and pressing.

Preferably, the telescopic device is one of a hydraulic cylinder and an air cylinder.
