As shown in fig. 1-4, the utility model provides a blade welding frock for the auxiliary working personnel welds a plurality of blades in the axis of rotation, and this frock includes bottom plate 10, rotor plate 20, drive assembly 30 and rotating assembly 40.

The base plate 10 is placed on the ground.

The rotating plate 20 is obliquely arranged above the bottom plate 10, a first side of the rotating plate 20 is rotatably connected with the bottom plate 10, and a second side of the rotating plate 20 is a free side.

The driving assembly 30 is used to control the second side of the pivotal plate 20 to move up and down.

The rotating assembly 40 includes a disc 41, a limiting cylinder 42, and a first motor 43. The disk 41 is disposed on the pivotal plate 20 and is rotatably coupled to the top of the pivotal plate 20. The limiting cylinder 42 is a hollow cylindrical structure, the limiting cylinder 42 is installed at the top of the disc 41, the axis of the limiting cylinder 42 is collinear with the axis of the disc 41, and the limiting cylinder 42 is adapted to the rotating shaft. The first motor 43 is installed on the rotating plate 20 for controlling the rotation of the disc 41, and the first motor 43 is electrically connected with an external control cabinet.

Before the use, the staff controls the driving assembly 30, and when the driving assembly 30 is started, the second side of the rotating plate 20 moves up and down until the rotating plate 20 is adjusted to a position suitable for the staff. The staff inserts tightly the first end of axis of rotation in the spacing section of thick bamboo 42, and the middle part and the second end of axis of rotation all expose outside this moment.

The specific working process is as follows: firstly, a worker takes the blades, the blades are longitudinally placed at the highest point of the peripheral surface of the rotating shaft, the contact surfaces of the blades and the rotating shaft are welded, after the welding of the blades is completed, the worker controls the first motor 43 to be started through the external control cabinet, the first motor 43 drives the rotating shaft of the disc 41 and the limiting cylinder 42 to rotate after being started until the next welding point of the rotating shaft moves to the highest point of the peripheral surface, and then the operation is repeated until all the blades are welded on the peripheral surface of the rotating shaft. Whole working process, under rotating assembly 40's effect, the welding point of axis of rotation all can remove the peak of outer peripheral face in proper order, therefore the staff need not change own position just can weld the blade of each position, and convenient operation has improved work efficiency.

Further, the driving assembly 30 includes a guide bar 31, a slider 32, a lead screw 33, a second motor 34, and a connecting bar 35. The guide rod 31 is transversely arranged, and both ends of the guide rod are fixedly connected with the top of the bottom plate 10. The slider 32 is provided on the guide bar 31 and slidably connected to the guide bar 31. The screw rod 33 transversely penetrates through the sliding block 32, two ends of the screw rod are rotatably connected with the top of the bottom plate 10, and the screw rod 33 is in threaded connection with the sliding block 32 and is parallel to the guide rod 31. The second motor 34 is installed on the bottom plate 10 and used for controlling the screw rod 33 to rotate, and the second motor 34 is electrically connected with an external control cabinet. A first end of the connecting rod 35 is rotatably connected to the slider 32, and a second end of the connecting rod 35 is rotatably connected to the rotating plate 20.

The staff just can control second motor 34 through external control cabinet and start, and second motor 34 drives lead screw 33 rotation when starting, and under the effect of guide bar 31, slider 32 will remove about, and under the effect of connecting rod 35, the second side of rotor plate 20 just can reciprocate, up to adjusting to the position that suits with the staff.

The driving assembly 30 with such a structure can facilitate the worker to quickly adjust the position of the rotating plate 20, thereby further facilitating the worker to operate.

Further, still include a plurality of locating pieces 50, a plurality of locating pieces 50 are in proper order equally spaced along the circumference of spacing section of thick bamboo 42 and are arranged, and the locating piece 50 is last to be opened has the spacing groove that runs through, and the spacing groove corresponds with spacing section of thick bamboo 42, and the spacing groove suits with the blade.

Preferably, the number of positioning blocks 50 is equal to the number of vanes. When the rotating assembly 40 is started and a certain positioning block 50 moves to the uppermost position, a worker inserts the blade into the limiting groove, knows that the bottom of the blade is in contact with the rotating shaft, and then welds the contact surface.

On one hand, due to the design of the positioning block 50 and the positioning groove 51, when a worker welds, the worker does not need to hold the blade by hand, and the operation is further convenient; on the other hand, since the plurality of positioning blocks 50 are sequentially arranged at equal intervals along the circumferential direction of the limiting cylinder 42, the blades after final welding are also equidistant, and therefore, other positioning tools are not needed during welding.

Further, a rubber ring is mounted on the inner wall of the limiting cylinder 42. The rubber ring is designed to protect the rotating shaft on one hand and prevent the rotating shaft from directly contacting the limiting cylinder 42; on the other hand, the friction between the rotating shaft and the limiting cylinder 42 is increased, and the rotating shaft is prevented from falling off.

Further, a tool box 12 is installed on the top of the bottom plate 10, and the tool box 12 is open and used for accommodating other tools.

Further, a plurality of casters 11 with self-locking function are installed at the bottom of the bottom plate 10 to facilitate the movement of the tool by the worker.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
