Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing and measurement technology, and in particular to a rapid angle and dimension detection gauge. Background Technology

[0002] In the process of product assembly, the inspection of angular dimensions (the angle between the product end face and the component axis) is usually carried out using CMM for quantitative inspection and dedicated angle gauges for qualitative inspection. When the dedicated angle gauge determines that the product is unqualified, quantitative inspection is required, but CMM inspection has a long waiting time, which affects production efficiency. Moreover, the dedicated angle gauges have a long manufacturing cycle and high cost. This utility model can convert the angular dimension into the bolt head height dimension and design a rapid inspection device, which can make the inspection more convenient, faster and more efficient. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rapid angle dimension detection fixture, comprising: a workshop inspection plate, a fixture base, a fixture body, a dial indicator calibration column, and a dial indicator, characterized in that an opening groove is designed on one side of the fixture body, and the fixture body is used to determine whether the angle dimension of the product is qualified by its own relative movement; when the product component connector can pass smoothly through one side of the opening groove, it indicates that the angle dimension is qualified; if it cannot pass smoothly, the angle dimension exceeds the specified range.

[0005] Optionally, the opening slot of the inspection device is designed to be adjustable to accommodate connectors of different sizes.

[0006] Optionally, the inspection fixture base is placed on the workshop inspection plate, and the inspection fixture body is fixed on top of the inspection fixture base and is in close contact with the workshop inspection plate to ensure stability and accuracy during the inspection process.

[0007] Optionally, the inspection device is specifically designed with the dial indicator calibration column, and a dial indicator base is located above the dial indicator calibration column for fixing and placing the dial indicator.

[0008] Optionally, the dial indicator is provided on the upper side of the dial indicator base opposite to the opening slot, for further measuring and determining the specific deviation value of the angular dimension.

[0009] Optionally, a fixing block is provided at the position where the dial indicator is placed on the dial indicator base to fix the dial indicator. The upper and lower ends of the contact surface between the fixing block and the dial indicator are provided with indicator sleeves to protect the dial indicator.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] This utility model is applicable to the rapid detection of angular dimensions during product assembly in the mechanical field, especially suitable for the rapid detection of precision angles. The inspection fixture, based on the design dimensions and tolerance requirements of the product to be inspected, converts angle measurement into dimensional measurement. Specifically, it converts the angle between the end face of the product and the axis of the component into the elevation dimension of the connector. The angle is judged to be qualified by detecting whether the elevation dimension of the connector is within a preset range. A dial indicator, used in conjunction with a calibration column, can be zeroed during the inspection process and accurately measure and display the angle deviation value, thereby achieving precise control of the angular dimensions. The fixture has a simple structure, is easy to manufacture and operate, reduces production costs, improves inspection efficiency, and solves the problems of dedicated inspection fixtures being unable to perform quantitative inspections and long waiting times for CMM inspections.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides, for example Figures 1 to 3 The technical solution shown is a rapid angle dimension detection fixture, comprising: a workshop inspection plate 1, a fixture base 2, a fixture body 3, a dial indicator calibration column 4, and a dial indicator 8. The fixture body 3 is characterized by having an opening slot on one side. The fixture body 3 is used to determine whether the product's angle dimension is qualified by its own relative movement. When the product component connector can pass smoothly through one side of the opening slot, the angle dimension is qualified; if it cannot pass smoothly, the angle dimension exceeds the specified range.

[0018] The opening groove of the inspection device 3 is designed to be adjustable to accommodate connectors of different sizes.

[0019] The opening groove design of the inspection device 3 is customized according to the actual size and shape of the product component connector to ensure accurate matching during the inspection process.

[0020] The inspection base 2 is placed on the workshop inspection plate 1, and the inspection body 3 is fixed on top of the inspection base 2 and is in close contact with the workshop inspection plate 1 to ensure stability and accuracy during the inspection process.

[0021] The workshop inspection plate 1 is the foundation of the entire mechanism, providing a stable and level surface for placing and fixing other components; the fixture base 2 is closely attached to the workshop inspection plate 1, providing a stable support structure, fixing and supporting the entire fixture structure, and ensuring the stability of the overall structure.

[0022] The inspection unit 3 is designed with the dial indicator calibration column 4, and the dial indicator base 5 is above the dial indicator calibration column 4 for fixing and placing the dial indicator 8.

[0023] The dial indicator 8 is located on the upper side of the dial indicator base 5 opposite to the opening slot, and is used to further measure and determine the specific deviation value of the angular dimension.

[0024] The dial indicator 8, used in conjunction with the dial indicator calibration column 4, can be zeroed during the testing process and accurately measure and display the angle deviation value, thereby achieving precise control of the angle dimension.

[0025] Before testing, the dial indicator 8 needs to be calibrated to zero. If the dial indicator 8 displays a positive value during testing, it indicates that the angle dimension is too small. If it displays a negative value, it indicates that the angle dimension is too large, and the angle dimension fixture needs to be adjusted accordingly.

[0026] A fixing block 6 is provided at the position where the dial indicator 8 is placed on the dial indicator base 5 to fix the dial indicator 8. The upper and lower ends of the contact surface between the fixing block 6 and the dial indicator 8 are provided with instrument sleeves 7 to protect the dial indicator 8.

[0027] The dial indicator calibration column 4 and the dial indicator 8 are securely connected to the inspection body 3 via the fixing block 6 and the instrument sleeve 7, ensuring stability and accuracy during the measurement process.

[0028] The following description, in conjunction with a preferred embodiment, illustrates the content involved in the above embodiments.

[0029] In this embodiment, the angle between the end face of the product and the axis of the component needs to be detected, as shown in the attached figure. Figure 2As shown, the customer requires an angle dimension of 6.3°±1° (the line connecting the end face of the product to the rocker arm assembly connector and the welding hole). Based on the drawing requirements, this was changed to dimensional measurement. Since the rocker arm assembly is a precision casting, the connector diameter Ø10 tolerance is controlled within ±0.01mm, having minimal impact on the measured dimensions. Therefore, the angle measurement was converted to a dimensional measurement. The product angle dimension is 6.3°±1° (theoretical height is 76.21mm), which translates to controlling the height of the connector within the range of 65.69mm-76.73mm.

[0030] The specific operation is as follows: Place the product on the testing plate with the components in a closed state; align the angle gauge and gauge base 2 firmly with the workshop testing plate 1; move one side of the gauge with the opening slot through the product component connector. If it passes smoothly, the angle is qualified; if it fails, the angle dimension is out of tolerance; to understand the size of the angle deviation, use the other side of the gauge (the side with the dial indicator), and zero the dial indicator 8. If the dial indicator reading is positive, the angle dimension is too small; if it is negative, the angle is too large, and the angle fixture needs to be adjusted accordingly.

[0031] This utility model is applicable to the rapid detection of angular dimensions during product assembly in the mechanical field, especially suitable for the rapid detection of precision angles. The inspection fixture, based on the design dimensions and tolerance requirements of the product to be inspected, converts angle measurement into dimensional measurement. Specifically, it converts the angle between the end face of the product and the axis of the component into the elevation dimension of the connector. The angle is judged to be qualified by detecting whether the elevation dimension of the connector is within a preset range. A dial indicator, used in conjunction with a calibration column, can be zeroed during the inspection process and accurately measure and display the angle deviation value, thereby achieving precise control of the angular dimensions. The fixture has a simple structure, is easy to manufacture and operate, reduces production costs, improves inspection efficiency, and solves the problems of dedicated inspection fixtures being unable to perform quantitative inspections and long waiting times for CMM inspections.
