Abstract
The utility model discloses a fan blade height detection device. The device comprises a datum plate (1), the upper surface of the datum plate (1) is a datum plane (1.1), the upper surface of the datum plate (1) is provided with a round lengthened seat (2), the round lengthened seat (2) is fastened on the datum plate (1) by a fastener (3), the diameter of the round lengthened seat (2) is matched with the inner diameter of a shell of a rotor, the center of the round lengthened seat (2) is provided with a shaft hole (4) which is in rotary fit with a center shaft of the rotor, and the datum plate (1) is provided with an elongated hole (5) which is coaxial with the shaft hole (4) and has the same diameter as the shaft hole (4). The fan blade height detection device disclosed by the utility model can be used for detecting heights of lower low points and upper high points of all blades of a fan.
Description
Technical field
The utility model relates to a kind of checkout equipment that is specifically designed to the blade assembling height that detects fan blade for axial cooling air machine of external rotor, specifically is a kind of impeller of blower height detecting device.
Background technology
External rotor axial-flow fan mainly partly is comprised of fan blade, rotor, guard, lead wire etc., and after each blade of fan blade was welded on the rotor case, whether the height of the lower low spot of each blade and upper high point met the requirements, and this just is badly in need of a kind of checkout equipment and detects.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, and highly whether a kind of lower low spot that can be used for detecting each blade of fan blade and upper high point satisfactory impeller of blower height detecting device is provided.
Technical solution of the present utility model is, provide a kind of impeller of blower height detecting device with following structure: comprise datum plate, the upper surface of described datum plate is reference field, the upper surface of described datum plate is provided with a circle and adds swinging seat, this circle adds swinging seat and is fastened on the datum plate by securing member, described circle adds the diameter of swinging seat and the internal diameter of rotor case matches, the center that this circle adds swinging seat is provided with the axis hole that is rotatably assorted with the rotor center axle, and described datum plate is provided with the elongated pore of and equal diameters coaxial with axis hole.
Be provided with altogether a ball bearing in described axis hole and the elongated pore.
After adopting above structure, the utility model impeller of blower height detecting device compared with prior art, have the following advantages: the rotor case that will be welded with each blade of fan blade is fastened in circle and adds on the swinging seat, the rotor center axle is inserted in axis hole and the elongated pore, utilize ruler just can detect lower low spot height and the upper high some height of each blade of fan blade, compare with standard value by detected value, whether just can draw detected value meets the demands, thereby successfully realized testing goal, effective guarantee product quality.
As improvement, be provided with altogether a ball bearing in described axis hole and the elongated pore, be convenient to be welded with the rotation of the rotor of each blade of blower fan detect at same position so that testing tool is ruler, Effective Raise accuracy of detection.

The structural representation at the back side of Fig. 2 the utility model impeller of blower height detecting device.
As shown in the figure:
1, datum plate, 1.1, reference field, 2, circle adds swinging seat, 3, securing member, 4, axis hole, 5, elongated pore, 6, ball bearing.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in drawings, impeller of blower height detecting device of the present utility model comprises datum plate 1, and the upper surface of described datum plate 1 is reference field 1.1.The upper surface of described datum plate 1 is provided with a circle and adds swinging seat 2, and this circle adds swinging seat 2 and is fastened on the datum plate 1 by securing member 3.Described circle adds the diameter of swinging seat 2 and the internal diameter of rotor case matches.The center that this circle adds swinging seat 2 is provided with the axis hole 4 that is rotatably assorted with the rotor center axle.Described datum plate 1 is provided with the elongated pore 5 of and equal diameters coaxial with axis hole 4.
In the present embodiment, described axis hole 4 and the elongated pore 5 interior ball bearing 6 that are provided with altogether; Described datum plate 1 adopts No. 45 steels to form, and the thickness of described datum plate 1 can be between 10～40mm, in the present embodiment, and preferred 20mm; Described circle adds the center that swinging seat 2 is positioned at datum plate 1, and described datum plate 1 also is the circular slab body structure.
During use, impeller of blower height detecting device horizontal positioned of the present utility model, the reference field of datum plate up, after being loaded on pick-up unit, the rotor that is welded with each blade of fan blade is the level of state, at this moment, the outer peripheral minimum point of each blade of fan blade is lower low spot, and outer peripheral peak is high point.During detection, utilize ruler to measure the height that lower low spot to the distance of reference field just can be measured lower low spot, can measure equally the height of high point, by comparing with critical field value (the scope of design value of design process), just can detect and whether meet the requirements.
Claims (2)
1. impeller of blower height detecting device, it is characterized in that: comprise datum plate (1), the upper surface of described datum plate (1) is reference field (1.1), the upper surface of described datum plate (1) is provided with a circle and adds swinging seat (2), this circle adds swinging seat (2) and is fastened on the datum plate (1) by securing member (3), described circle adds the diameter of swinging seat (2) and the internal diameter of rotor case matches, the center that this circle adds swinging seat (2) is provided with the axis hole (4) that is rotatably assorted with the rotor center axle, and described datum plate (1) is provided with the elongated pore (5) of and equal diameters coaxial with axis hole (4).
