Error-proofing clamp for press-mounting wind wheel

Abstract

The invention relates to an error-proofing clamp for press-mounting a wind wheel. The error-proofing clamp comprises a control handle controlled by an electromagnetic valve, left and right cylinders on which ejector rods are arranged, left and right push blocks on which guide cylinders are arranged, left and right guide tracks capable of enabling the guide cylinders to slide on the guide tracks, and an intermediate bottom plate on which a positioning column for a position-limiting motor is arranged. As a plurality of error-proofing convex fins with the shape and size which are in line with the shape and size of a gap between two adjacent blades on the wind wheel in a stretched state are additionally arranged on the outer surfaces of the push blocks and guide cylinders in the axial direction, the wind wheel can only be sheathed on the guide cylinders under the condition that the shape and size of the gap between the blades are in line with the shape and size of the error-proofing convex fins in the stretched state, thus the occurrence of the wrong sheathing situation of the wind wheel can be avoided, the correctness of the directions of the blades of the wind wheel which is mounted on the motor is ensured, the error-proofing clamp is further favorable for ensuring the product quality, improving the production efficiency, lowering the production cost as well as relieving the working strength and mental pressure of operators, and the error-proofing camp further has very strong practicality.

Description

technical field [0001] The invention relates to the technical field of tooling equipment, in particular to a wind wheel press-fitting and anti-error fixture suitable for assembling the wind wheel to the periphery of the motor during the fan manufacturing process. Background technique [0002] The wind wheel is an important part of the fan that determines the air supply direction when the fan is working. In the complete machine state, the wind wheel is set on the periphery of the motor, and is set on the end shafts on both sides of the motor by aligning and pressing the shaft holes. Currently commonly used wind wheel pressing fixtures such as figure 1 As shown, it is mainly controlled by the solenoid valve 2 and the control handle 3, the left and right cylinders 4 with the ejector rod 1 on the top, the left and right push blocks 6 with the guide cylinder 5 on the top, and the left and right push blocks 6 that can slide on the top. The guide rail 7 and the middle base plate 9...
