Description

Technical Field

[0001] The utility model relates to the technical field of automobile air-conditioning production, in particular to a height detection device. Background Art

[0002] The blower is a key component in the automotive air conditioner. The blower includes a motor and a fan blade. The press machine presses the fan blade and the motor together to assemble the blower. There are strict requirements for the height of the blower after press assembly. If the height of the blower is too high, it is easy to interfere with the air conditioner housing. If the height of the blower is too low, it is easy to cause interference between the fan blade and the motor.

[0003] Under the condition of ensuring the stability of the press, the height of the blower assembly needs to be checked. The current method of measuring the height of the blower is to use a height gauge.

[0004] In the prior art, the fan blade surface needs to be placed on a reference plane for measurement. The fan blade is easily deformed, and the height values ​​at multiple angles need to be measured. After measuring a dimension, the entire blower needs to be rotated by an angle, which is inefficient. In addition, the use of a height gauge requires high professional skills of the staff, and is not suitable for factory mass production. When the reference plane for measurement is an inclined plane, it is difficult to read the height gauge.

[0005] Therefore, there is an urgent need for a height detection device to solve the above problems. Utility Model Content

[0042] The blower is a key component in the automotive air conditioner. The blower includes a motor and a fan blade. The fan blade is set on the motor. The press machine presses the fan blade and the motor together to assemble the blower. There are strict requirements for the height of the blower after press assembly. If the height of the blower is too high, it is easy to interfere with the air conditioner housing. If the height of the blower is too low, it is easy to cause interference between the fan blade and the motor.

[0043] In the prior art, the fan blade surface needs to be placed on a reference plane for measurement. The fan blade is easily deformed, and the height values ​​at multiple angles need to be measured. After measuring a dimension, the entire blower needs to be rotated by an angle, which is inefficient. In addition, the use of a height gauge requires high professional skills of the staff, and is not suitable for factory mass production. When the reference plane for measurement is an inclined plane, it is difficult to read the height gauge.

[0044] In order to solve the above problems, this embodiment provides a height detection device 100 for detecting the height of the blower. Figure 1 and Figure 2 As shown, the height detection device 100 includes at least two positioning mechanisms 10 and at least one detection mechanism 20. The at least two positioning mechanisms 10 are arranged at intervals along the circumference of the motor. The positioning mechanism 10 has a reference surface 111. The reference surface 111 is used to support the side of the motor away from the fan blades. At least one detection mechanism 20 can be placed on the reference surface 111 of any positioning mechanism 10. The detection mechanism 20 is provided with an upper limit value and a lower limit value of the blower height for height detection of the blower.

[0045] During detection, the motor is placed on the reference plane 111, and the fan blades are arranged on the side of the motor away from the reference plane 111. The upper limit value and the lower limit value on the detection mechanism 20 are used to determine whether the height between the reference plane 111 and the fan blades is within the qualified range, and then it can be quickly identified whether the height of the blower is within the qualified range, thereby improving the detection efficiency. It should be noted that the detection mechanism 20 is any existing stop gauge that can achieve the above-mentioned function. At least one detection mechanism 20 can be placed on the reference plane 111 of any positioning mechanism 10, and the height of multiple points of the blower can be measured. The motor is placed on the reference plane 111, and the fan blades are arranged on the side of the motor away from the reference plane 111, which can ensure that the fan blades are not subjected to force and are not deformed, thereby ensuring the accuracy of the detection. The positioning mechanism 10 determines the position of the motor plane during the blower height detection. Even if the motor plane is an inclined surface, the measuring position on the inclined surface can be directly placed on the reference plane 111 during measurement to detect whether the height between the measuring position and the fan blade is within a qualified range. This solves the problem of difficulty in height detection when the measured surface of the blower motor is an inclined surface.

[0046] Preferably, since the heights of each position of the fan blade are different, there are three positioning mechanisms 10, which can quickly and conveniently detect whether the heights of the three positions of the blower are qualified, and can conveniently rotate the blades of the fan blade to detect the height of the entire circumference of the fan blade.

[0047] like Figure 1 and Figure 2 As shown, the heights of the two ends of the detection mechanism 20 along the length direction are different, the height of one end is the lower limit of the blower height, and the height of the other end is the upper limit of the blower height, which is convenient for the staff to intuitively detect whether the blower height is within the qualified range, reducing the difficulty of detection. Preferably, the detection mechanism 20 is made of metal material, which has the advantages of high strength and increases the service life of the detection mechanism 20.

[0048] The positioning mechanism 10 includes a positioning member 11, which is provided with a slide groove 112, and the detection mechanism 20 is slidably arranged in the slide groove 112, so that the staff can quickly place the detection mechanism 20 on the positioning member 11, thereby further improving the detection efficiency. It is understandable that the bottom of the slide groove 112 is the reference surface 111.

[0049] The positioning mechanism 10 includes a limiter 12, and the detection mechanism 20 is provided with a groove 21 adapted to the limiter 12. The limiter 12 can be inserted into the groove 21 to ensure that the detection mechanism 20 does not need to be held by a worker when measuring. In other embodiments, the positioning member 11 can also be provided on the detection mechanism 20, and the groove 21 is provided on the positioning mechanism 10, which is not limited here.

[0050] There are at least two limit members 12 , and at least two limit members 12 are respectively arranged on both sides of the slide slot 112 , to ensure that the detection mechanism 20 is placed flat, reduce the error caused by the person holding the measuring tool, and improve the test accuracy.

[0051] The height detection device 100 further includes a base 30 , on which the positioning mechanism 10 is disposed, and the base 30 achieves a stable bearing effect on the positioning mechanism 10 .

[0052] The height detection device 100 further includes a handle 40, which is disposed on the base 30. The handle 40 is convenient for the staff to hold and to facilitate the staff to transfer the height detection device 100. This solves the problem in the prior art that the blower needs to be sent to a measurement room or a specific location for measurement.

[0053] Preferably, there are two handles 40 , which are respectively disposed at both ends of the base 30 along the length direction. The two handles 40 allow workers to receive balanced force when carrying the height detection device 100 , thereby facilitating the picking up and carrying of the height detection device 100 .

[0054] The positioning member 11 is provided with a weight-reducing hole 113 , which can reduce the overall weight of the height detection device 100 and facilitate the carrying of the staff.

[0055] The height detection device 100 further includes a storage box 50 , which is disposed on the base 30 . The storage box 50 is used to store the detection mechanism 20 . The detection mechanism 20 can be placed in the storage box 50 after use to prevent the detection mechanism 20 from being lost.

[0056] Note that in the description of this specification, the description with reference to the terms "some embodiments", "other embodiments", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.
