DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The utility model provides Figure 1-5 The impeller processing and assembly equipment shown includes a workbench 1, the top of which is fixedly connected to a fixing frame 2, on which a pressing mechanism 3 is provided. The pressing mechanism 3 is an existing device that can press the impeller and the shaft together through a transmission member such as a hydraulic cylinder.

[0034] Furthermore, a loading mechanism 4 is rotatably provided at the top of the workbench 1, and the loading mechanism 4 includes: a turntable 41, a bearing base 42, a clamping assembly 43 and a positioning assembly 44. The turntable 41 is rotatably provided at the top of the workbench 1; multiple bearing bases 42 are equidistantly fixedly connected to the top of the turntable 41; the clamping assembly 43 is provided on the bearing base 42 for fixing the impeller; the positioning assembly 44 is provided inside the workbench 1 for multi-point positioning of the turntable 41. By providing multiple bearing bases 42 on the turntable 41, the multiple bearing bases 42 can be rotated to the bottom of the pressing mechanism 3 in turn through the positioning assembly 44, so that when the pressing mechanism 3 presses and assembles the impeller fixed on the bearing base 42, the impellers pressed on the remaining bearing bases 42 can be disassembled, and new impellers to be pressed can be replaced and fixed through the clamping assembly 43, which reduces the operational risk of the work and speeds up the assembly efficiency of large quantities of impellers, making it easy to use.

[0035] Specifically, the clamping assembly 43 includes: a bidirectional screw 431, a slider 432 and a clamping plate 433. An adjustment groove is provided at the top of the supporting base 42, and both ends of the bidirectional screw 431 are rotatably connected to the inner wall of the adjustment groove; the slider 432 and the bidirectional screw 431 form a screw transmission; the clamping plate 433 is fixedly connected to the top of the slider 432, and multiple clamping plates 433 are symmetrically arranged on the supporting base 42. The cross-section of the clamping plate 433 is arc-shaped. The rotation of the bidirectional screw 431 can make the multiple sliders 432 approach or move away from each other, so that impellers of different specifications can be clamped and fixed, which increases the practicality of the device.

[0036] Furthermore, the inner wall of the clamping plate 433 is fixedly connected to a rubber pad 5, and the outer wall of the rubber pad 5 is provided with an anti-slip texture. The rubber pad 5 increases the friction between the clamping plate 433 and the impeller, so that the impeller can be clamped more stably. At the same time, it also protects the impeller so that the impeller will not be clamped by the clamping plate 433.

[0037] Specifically, the positioning assembly 44 includes: a positioning rod 441, a sliding rod 442, a compression spring 443, a connecting rope 444 and a pedal 445. An extrusion groove is provided inside the workbench 1. Both ends of the positioning rod 441 are slidably and interlacedly connected with the inner wall of the extrusion groove. A plurality of positioning holes are equidistantly provided at the bottom end of the turntable 41. The two ends of the positioning rod 441 are slidably and interlacedly connected with the inner cavities of the plurality of positioning holes; the two ends of the sliding rod 442 are fixedly connected with the top and bottom ends of the inner wall of the extrusion groove, and the positioning rod 441 is slidably and interlacedly connected with the plurality of sliding rods 442; the compression spring 443 is sleeved on the outside of the sliding rod 442, one end of the compression spring 443 is fixedly connected to the positioning rod 441, and the other end of the compression spring 443 is fixedly connected to the bottom of the inner wall of the extrusion groove. The two ends are fixedly connected, and the compression spring 443 is always in a compressed state, thereby providing a stable elastic force to the positioning rod 441, so that the positioning rod 441 always extends out of the workbench 1 and is inserted into the positioning hole, so that the turntable 41 can be positioned at multiple points; one end of the connecting rope 444 is fixedly connected to the positioning rod 441; the pedal 445 is arranged inside the workbench 1, and the pedal 445 is fixedly connected to the other end of the connecting rope 444. The staff can extend their feet into the inside of the pedal 445, so that the connecting rope 444 can pull the positioning rod 441 by applying force with their feet, thereby releasing the positioning of the turntable 41, making it convenient to rotate out the processed impeller, and rotate the impeller to be processed to the bottom of the pressing mechanism 3.

[0038] Furthermore, a reversing groove is opened inside the workbench 1, and a plurality of reversing wheels 6 are fixedly installed inside the reversing groove. The connecting rope 444 cooperates with the plurality of reversing wheels 6. The setting of the reversing wheel 6 changes the landing point of the connecting rope 444, so that the pedal 445 can be close to the edge of the workbench 1, which is convenient for the staff to sit on the edge of the workbench 1 for use.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
