Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.
Referring to fig. 1 to 6, the automatic shaping mechanism for the front disk of the large fan impeller includes a base 100, an impeller fixing seat 111 and a shaping cushion block 110, wherein the impeller fixing seat 111 and the shaping cushion block are arranged on the base 100. In order to facilitate the installation and position adjustment of the components, a plurality of installation grooves 115 are formed on the base 100. The base 100 must be firmly secured to ensure that the ground or platform is sufficiently strong when subjected to shaping forces.
The base 100 is further provided with a shaping pressing mechanism, and the shaping pressing mechanism is matched with the shaping cushion block 110 to extrude and shape the front disc of the impeller 114 fixed on the impeller fixing seat 111. In this embodiment, the top of the shaping pad 110 is an arc surface structure 110a adapted to the shape of the front disk of the impeller 114. The shaping pressing mechanism comprises a jacking mechanism arranged on the base 100, a force arm seat 106 and a force arm 107, wherein the middle part of the force arm seat is rotatably arranged on the top part 105 of the force arm seat through a rotating shaft 104, one end of the force arm 107 is connected with the moving end of the jacking mechanism, and the other end of the force arm is provided with a shaping pressing block 109 matched with a shaping cushion block 110. Preferably, the jacking mechanism is a jack 101, which can be an electric hydraulic jack, the bottom of the jack 101 is fixed on the base 100, and the head of the jack 101 is connected with one end of the force arm 107. The force on the front disc of the impeller is determined by the length of the arm 107 and the size of the jack 101, and the jack 101 can be selected according to the size of the impeller by changing the pressure by changing the length of the arm. The head of the jack 101 is movably connected to the force arm 107 through a second connecting block 103 which is arranged on the force arm 107 in a sliding mode, the head of the jack 101 is movably connected with the second connecting block 103, and specifically, a ball head connecting structure 102 is arranged between the head of the jack 101 and the second connecting block 103. The shaping pressing block 109 is movably connected to the force arm 107 through a first connecting block 108 which is arranged on the force arm 107 in a sliding mode, the bottom of the shaping pressing block 109 is of a spherical structure 109a, when the force arm 107 swings, the shaping pressing block 109 swings, but the spherical structure 109a can still extrude and shape the front disc of the impeller, and the purpose of adjusting the position of the front disc of the impeller to be shaped is achieved by adjusting the position of the shaping pressing block 109. When the impeller is stressed and shaped, the stress of the front disc of the impeller 114 finally acts on the impeller supporting seat 111 and the shaping cushion block 110 through the impeller.
In order to facilitate operation and ensure that the front disc of the impeller can be shaped completely, a hydraulic jacking device 112 is arranged in the middle of the impeller fixing seat 111, and a rotatable supporting seat 113 connected with the middle of the impeller 114 is arranged at the top of the hydraulic jacking device 112. When other positions need to be shaped, the impeller 114 is jacked up by the hydraulic jacking device 112, the impeller 114 can be rotated to a proper position at the moment due to the connection of the impeller 114 and the rotatable supporting seat 113, and then the impeller 114 is put down by the hydraulic jacking device 112, so that the impeller 114 is supported on the impeller fixing seat 111. The outer periphery of the top of the impeller fixing seat 111 in this embodiment is provided with a positioning step 111a, which not only can be in positioning fit with the middle of the impeller 114, so that the impeller 114 can be kept stable during shaping, but also can play a centering role with the impeller 114.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
