Description

Technical Field

[0001] This utility model relates to a testing device in the field of automotive parts processing, and in particular to a multi-parameter testing fixture for flanges. Background Technology

[0002] Currently, in the field of machining, multi-parameter testing of flanges for components such as pulleys and fan brackets, including installation height, axial runout of the end face, and radial runout of the stop, is crucial and directly affects the reliability, lifespan, and safety of the power transmission system. Current common testing methods include using standard gauges, magnetic universal joints, and indicators to measure installation height, axial runout of the end face, and radial runout of the stop separately. This method has advantages such as low cost and high versatility, but it suffers from the following technical drawbacks: it requires adjusting each measurement element individually, resulting in low testing efficiency and unsuitability for batch testing. An engine fan bracket testing device disclosed in authorization announcement number CN216482928U, while capable of detecting the starting torque of the fan bracket flange, the flange height and clearance value, and the flange side vibration value, still has the following shortcomings: the detection of flange side vibration only refers to radial vibration of the flange side, without mentioning the detection of axial vibration of the flange end face; moreover, its structure is complex and inconvenient to operate. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a multi-parameter testing fixture for flanges, so as to overcome the shortcomings of the existing technology, such as low testing efficiency, lack of detection of axial vibration of flange end face, complex structure and inconvenient operation.

[0004] The technical solution to the above-mentioned technical problems is: a multi-parameter testing fixture for flanges, comprising: a base plate, a double-column height gauge, an indicator adjustment and fixing device, an axial indicator, a radial indicator, and a part to be measured; the part to be measured is mounted on the base plate, and the indicator adjustment and fixing device includes a mounting plate, a radial indicator slider, and an axial indicator slider. The mounting plate is respectively provided with a radial slider guide groove and an axial slider guide groove. The radial indicator is mounted on the radial slider guide groove via the radial indicator slider, and the axial indicator is mounted on the axial slider guide groove via the axial indicator slider. The mounting plate is fixedly mounted on the measuring claw of the double-column height gauge, and the double-column height gauge is rotatably mounted on the base plate.

[0005] A further technical solution of this utility model is: a positioning block for positioning and supporting the double column height gauge is also installed on the base plate, and the bottom end of one column of the double column height gauge passes through the positioning block and is connected to the base of the double column height gauge.

[0006] A further technical solution of this utility model is: the positioning block includes a support plate and a top plate connected together. The support plate is installed on the bottom plate. The front end of the top plate is provided with a semi-circular protrusion, and a positioning hole for passing through the support column is provided on the semi-circular protrusion. A copper sleeve that rotates with the support column is installed in the positioning hole.

[0007] A further technical solution of this utility model is: the base plate is also provided with a pin hole, which is connected to the bottom end of the support plate by a cylindrical pin.

[0008] A further technical solution of this utility model is: a quick-change positioning plate for the part to be tested is also installed on the base plate, and a positioning pin is installed on the top surface of the quick-change positioning plate for the part to be tested, and the part to be tested is installed on the positioning pin through the through hole at its bottom end.

[0009] A further technical solution of this utility model is: a quick-change connecting block is installed on the base plate, and the base plate is connected to the quick-change positioning plate of the part under test through the quick-change connecting block.

[0010] A further technical solution of this utility model is: the main scale slider of the double-column height gauge and the axial indicator constitute a main and auxiliary scale measuring system for measuring the height and parallelism of the flange.

[0011] A further technical solution of this utility model is: the reference end face, installation height, axial runout and radial runout of the part to be tested are the objects of detection.

[0012] Due to the above structure, the multi-parameter testing fixture for flanges of this utility model has the following advantages compared with the prior art:

[0013] 1. High detection efficiency

[0014] This utility model includes a base plate, a double-column height gauge, an indicator adjustment and fixing device, an axial indicator, a radial indicator, and a part to be measured. The indicator adjustment and fixing device includes a mounting plate, a radial indicator slider, and an axial indicator slider. The mounting plate has radial and axial slider guide grooves respectively. The radial indicator is mounted on the radial slider guide groove via the radial indicator slider, and the axial indicator is mounted on the axial slider guide groove via the axial indicator slider. The mounting plate is fixedly mounted on the measuring claw of the double-column height gauge, which is rotatably mounted on the base plate. In use, the double-column height gauge is used as the main scale, and the axial indicator as the auxiliary scale to measure the installation height of the flange. The axial indicator measures the axial runout of the flange end face, and the radial indicator measures the radial runout of the flange stop. After rotating the double-column height gauge to the measuring position, the flange of the part to be measured is rotated, and the axial and radial indicators are observed. After the flange of the part to be measured rotates more than one revolution, the data of the flange end face installation height, flange end face axial runout, and flange stop radial runout can be read. Therefore, this tooling can detect multiple measurement elements at once, greatly improving detection efficiency.

[0015] 2. It can simultaneously detect radial and axial vibrations of the flange.

[0016] Since the indicator adjustment and fixing device of this utility model includes a mounting plate, a radial indicator slider, and an axial indicator slider, and the mounting plate is respectively provided with a radial slider guide groove and an axial slider guide groove, the radial indicator is mounted on the radial slider guide groove through the radial indicator slider, and the axial indicator is mounted on the axial slider guide groove through the axial indicator slider; therefore, the indicator adjustment and fixing device of this utility model can realize independent adjustment of radial and axial detection through the radial and axial slider guide grooves, thereby simultaneously realizing the detection of radial and axial vibration of the flange.

[0017] 3. Accurate and rapid test results

[0018] After rotating the double-column height gauge to the measuring position, rotate the flange of the part being measured and observe the axial and radial indicators. After the flange of the part being measured has rotated more than one revolution, the data of the flange end face installation height, flange end face axial runout, and flange stop radial runout can be read. The test results are accurate and fast.

[0019] 4. Flexible rotation and easy operation

[0020] This utility model has a positioning block installed on the base plate. The bottom end of one of the columns of the double-column height gauge passes through the positioning hole of the positioning block and can rotate around the positioning hole. In use, the double-column height gauge can be flexibly rotated to the measurement position as needed, making it very convenient to operate.

[0021] In addition, this utility model has a quick-change positioning plate for the part to be tested installed on the base plate. The part to be tested can be directly fitted onto the positioning pin of the quick-change positioning plate through the through hole at its bottom, making it very convenient to replace the part to be tested.

[0022] 5. Will not scratch the surface of the coated part being tested.

[0023] In use, this invention simply requires placing the part to be measured onto the positioning pin of the quick-change positioning plate, then rotating the double-column height gauge to the measurement position, and then rotating the part to begin comprehensive measurement of multiple parameters. It eliminates the need for complex clamping fixtures and will not scratch the surface of the coated part, thereby improving product quality.

[0024] 6. Simple structure and low cost
