[0030] Example

[0031] like Figure 1 As shown, the utility model proposes a fan impeller mold manufacturing positioning device, including a bottom plate 1, a top frame 3 fixedly connected to the top of the bottom plate 1 through four groups of pillars 2, the positions of the bottom plate 1, the pillars 2 and the top frame 3 are fixed, and a processing module is installed on the top frame 3 to process and manufacture the fan impeller. It also includes a placement table 4 arranged on the top of the bottom plate 1 for placing a workpiece.

[0032] Specifically, the positioning device includes a positioning mechanism 5 installed on the placement table 4 for fixing and positioning the workpiece. The positioning mechanism 5 includes a fixed plate 51, a movable plate 52, a limiting rod 53, and a limiting seat 54. The fixed plate 51 is fixedly connected to the top of the placement table 4, and the position of the fixed plate 51 is fixed. The side of the placement table 4 away from the fan 6 is in the same plane as the side of the fixed plate 51. The movable plate 52 is arranged above the placement table 4, and the bottom of the movable plate 52 is in contact with the top of the placement table 4. Multiple groups of limiting rods 53 are fixedly connected to the side of the movable plate 52 away from the fixed plate 51, and the limiting rods 53 move synchronously with the movable plate 52. The limiting seat 54 fixedly connected to the top of the placement table 4 is slidably connected to the limiting rod 53, and is used to limit the movable plate 52 through the limiting rod 53 and the limiting seat 54 when the movable plate 52 moves, so that the movement of the movable plate 52 is smooth. The positioning mechanism 5 further includes a threaded rod 55, a threaded sleeve 56, and a hand wheel 57. The threaded rod 55 is rotatably connected to the side of the mobile plate 52 away from the fixed plate 51. The threaded sleeve 56 threadedly connected to the threaded rod 55 is fixedly connected to the top of the placement table 4. The threaded rod 55 moves along its own length direction when rotating, and drives the mobile plate 52 to move at the same time. The hand wheel 57 is installed at one end of the threaded rod 55 away from the mobile plate 52. The setting of the hand wheel 57 facilitates the rotation of the threaded rod 55.

[0033] For further information, see Figure 1 and Figure 3, the above positioning device further includes multiple groups of fans 6 for purging debris. The multiple groups of fans 6 are installed on a mounting plate 61, and the mounting plate 61 is installed on one side of two sets of struts 2. An adjusting assembly 7 for adjusting the height of the fans 6 is provided to facilitate purging the surfaces of fan impellers of different sizes. The adjusting assembly 7 includes a sliding block 71, a sliding sleeve 72, a first positioning hole 73, a positioning bolt 74, and a second positioning hole 75. The two sliding blocks 71 are respectively fixedly connected to both ends of the mounting plate 61, and the sliding block 71 moves synchronously with the mounting plate 61. The sliding block 71 is slidably connected in the sliding sleeve 72 installed on the side of the strut 2. The position of the sliding sleeve 72 is fixed, which is used to limit the movement of the sliding block 71 and make the movement of the mounting plate 61 stable. Multiple groups of first positioning holes 73 are equidistantly formed on the sliding block 71, and the positioning bolt 74 is threadedly connected to the first positioning hole 73. Multiple groups of second positioning holes 75 are equidistantly formed on the sliding sleeve 72, and the positioning bolt 74 is slidably connected to the second positioning hole 75. After the positioning bolt 74 passes through the second positioning hole 75, it is threadedly connected to the first positioning hole 73, thereby fixing the relative positions of the sliding block 71 and the sliding sleeve 72, and fixing the height of the mounting plate 61 and the fans 6.

[0034] Furthermore, as Figure 1 and Figure 4 shown, the above positioning device further includes three sets of baffles 8 for blocking debris. The three sets of baffles 8 are arranged in a "U" shape and are respectively installed between two adjacent sets of struts 2. A fixing block 81 is further installed on one side of the strut 2 close to the baffle 8, and the position of the fixing block 81 is fixed. A sliding hole 82 is formed at the top of the fixing block 81, and a plug rod 83 is slidably connected in the sliding hole 82. The plug rod 83 is fixedly connected to the side of the baffle 8, and the position of the baffle 8 is fixed through the fixing block 81 and the plug rod 83. Multiple groups of clamping plates 84 are installed at the bottom positions on both sides of the baffle 8, and the fixing block 81 is slidably connected between the two clamping plates 84, which is used to further limit the position of the bottom of the baffle 8 and make the position of the baffle 8 not easily change after installation.

[0035] In this embodiment, the impeller is first placed on the placement table 4, the hand wheel 57 is turned to drive the threaded rod 55 to rotate, and the threaded rod 55 threadedly connected to the fixed threaded sleeve 56 moves along its own length direction and drives the movable plate 52 to approach the fixed plate 51. At this time, the movable plate 52 moves smoothly under the limiting action of the limiting rod 53 and the limiting seat 54 and clamps the impeller. After the position of the fan 6 is moved up and down, and the position of the fan 6 corresponds to the top position of the impeller, the positioning bolt 74 is passed through the second positioning hole 75 and threadedly connected to the first positioning hole 73 to fix the position of the sliding block 71, so that the position of the mounting plate 61 and the fan 6 is fixed. Then, the mechanism module installed on the top frame 3 is started to cut the impeller, and at the same time, the fan 6 is started to blow the debris generated during the processing of the impeller, so that the debris moves in the direction away from the limiting rod 53 and falls on the top of the bottom plate 1 after hitting the baffle 8. Then, the baffle 8 is pulled upward and removed to facilitate the cleaning of the accumulated debris.

[0036] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
