Description

Technical Field

[0001] The invention relates to the technical field of sand blasting tools, and more particularly to a rotary clamping device for large blade sand blasting. Background Art

[0002] At present, the overall length of large blades ranges from 1800mm to 2160mm, and the sand blowing operation needs to be carried out in a double-station sand blowing machine. Due to the large number of large blades, there is no reliable connection method with the rotating mechanism of the sand blowing equipment. During operation, the root of the blade can only be placed on the bracket of the sand blowing equipment, and the blade body is placed on the processing platform of the sand blowing equipment. After the operator sand blows on one side, two people cooperate to flip the blade and then complete the sand blowing operation on the other side.

[0003] However, during the sand blowing operation of large blades, two operators are required to cooperate in lifting and flipping the large blades, and each flip requires opening the cabin door of the sand blowing machine, moving the platform out and then performing the flipping operation, which is inefficient. At the same time, parts are prone to collision during the lifting process, affecting the processing quality of parts. In addition, due to the large number of product models and inconsistent sizes of the blade root, there is no suitable clamping device during the sand blowing operation, resulting in the blades being loosely clamped and the parts being unstable.

[0004] Therefore, providing a rotary clamping device for large blade sand blasting with simplified operation is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0005] In view of this, the present invention provides a rotary clamping device for large-scale blade sand blowing, which has stable clamping and can realize automatic flipping during the sand blowing operation, thereby improving efficiency.

The openable and closable cylindrical clamp is vertically fixed at the top center of the bottom plate; the bottom plate is provided with a plurality of evenly distributed threaded holes.

[0008] By adopting the above scheme, the beneficial effects of the present invention are:

[0009] The large blades can be firmly clamped by the openable cylindrical clamp, and the bottom plate is bolted to the rotating mechanism of the sand blasting machine through the threaded holes on it, so that the blades and the rotating mechanism are stably and effectively connected, thereby realizing the automatic flipping of the large blades during the sand blasting operation, improving the processing efficiency, and effectively avoiding the risk of collision when lifting parts, thereby improving product quality.

[0010] Furthermore, it also includes a stopper or a transition sleeve, which is installed on the top of the base plate and located inside the openable and closable cylindrical fixture.

[0011] The beneficial effect of adopting the above further technical solution is that it is easy to stably place large blades.

[0013] The beneficial effect of adopting the above further technical solution is that the opening and closing function of the openable and closable cylindrical clamp is realized, which is easy to operate.

[0014] Furthermore, the wrench locking assembly includes a rotating shaft, a wrench screw and a wrench screw sleeve; the first arc-shaped clamping plate includes a first arc-shaped clamping plate body and a first docking plate connected as an integral whole with its side wall, and two first fixed plates distributed up and down are fixed between the first arc-shaped clamping plate body and the first docking plate, and the first docking plate has a first through hole; the second arc-shaped clamping plate includes a second arc-shaped clamping plate body and a second docking plate connected as an integral whole with its side wall, and the second docking plate corresponds to the position of the first docking plate, and the second docking plate has a second through hole corresponding to the position of the first through hole; the rotating shaft is vertically installed between the two first fixed plates; one end of the wrench screw is fitted and fixed on the rotating shaft, and the position of the wrench screw corresponds to the first through hole and the second through hole, and the other end of the wrench screw extends out of the second through hole; the wrench screw sleeve is screwed on the extended end of the wrench screw, and the outer diameter of the wrench screw sleeve is greater than the height of the second through hole.

[0015] The beneficial effect of adopting the above further technical solution is to achieve locking of the openable and closable cylindrical clamp.

[0016] Furthermore, the wrench locking assembly also includes a rotating handle, and the rotating handle is fixed on the wrench sleeve.

[0017] The beneficial effect of adopting the above further technical solution is that it is easy to screw the wrench sleeve.

[0018] Furthermore, two second fixing plates distributed up and down are fixed between the second arc-shaped clamping plate body and the second docking plate.

[0019] The beneficial effect of adopting the above further technical solution is to increase the stability of the second docking plate.
