Description

Technical Field

[0001] The utility model relates to the technical field of inventions, in particular to a novel qualitative inspection tool for multifunctional inspection of a traction motor installation interface. Background Art

[0002] According to different applications, gauges can be divided into the following categories:

[0003] A fixed fixture is a fixture connected to a workbench or a fixed device on it. It's typically used to clamp a workpiece and position it in a fixed location. It includes a reference plate, positioning blocks, and a clamping mechanism. Fixed fixtures offer high reliability and are used in demanding work environments. For example, these fixtures require a fixed workpiece position to ensure machining accuracy, such as in precision machining of parts.

[0004] A movable fixture is one that can be adjusted and moved during workpiece processing. It can be manipulated as needed, including adjusting its position and clamping method. A movable fixture consists of a pedal, pedal base, bracket, and clamping mechanism. Movable fixtures offer high flexibility and are suitable for batch production and high-variety production. For example, when inspecting workpieces of varying shapes, a movable fixture can be adjusted and moved to suit the workpiece, achieving optimal results.

[0005] Measuring fixtures are used to verify the dimensional and shape accuracy of workpieces. They utilize various measurement methods, such as optical and mechanical measurement. They consist of measuring tools and a measuring box. Because they accurately measure workpieces, they are suitable for applications requiring high measurement accuracy, such as precision machining and 3D printing.

[0006] Traction motors also require gauges in the actual production process. Therefore, industrial manufacturers need measuring gauges to control various product dimensions (such as aperture, spatial dimensions, form and position tolerances, etc.) to significantly improve production efficiency and effectively control quality. They are suitable for mass-produced products and can replace most professional measuring gauges. They need to be simple and practical in structure, multifunctional in detection, and low in cost.

However, it is worth noting that the present invention is not limited to these embodiments. In the detailed description of the present invention below, some specific details are described in detail. However, for the parts that are not described in detail, those skilled in the art can also fully understand the present invention.

[0032] In addition, those skilled in the art should understand that the drawings are only provided to illustrate the purpose, features and advantages of the present invention, and the drawings are not actually drawn to scale.

[0033] At the same time, unless the context clearly requires otherwise, words such as "include", "comprising" and the like throughout the specification and claims should be interpreted as inclusive rather than exclusive or exhaustive; that is, as "including but not limited to".

[0034] See also Figures 1-8 The present invention provides a technical solution: the positioning detection seat 1 is composed of a detection flange 101, a reinforcement plate 102, a detection bracket 103, and a support base 104. Made of alloy steel, it undergoes a process of blanking, pre-heat treatment, beveling, full penetration welding, post-aging treatment, rough machining, stress relief heat treatment, semi-finishing, finishing, and other processing to produce a qualified finished product. Its strength, rigidity, stability, and wear resistance are all well-guaranteed, achieving comprehensive detection functions. Among them:

[0035] The detection flange 101 is designed as an inner stop 105 , and the outer side of the inner stop 105 is provided with an introduction chamfer 107 to facilitate the flange installation of the traction motor 5 .

[0036] The detection flange 101 is designed as an internal stop 105. The internal stop 105 and its installation end surface have verticality requirements. The center line of the internal stop 105 and the H1 symmetrical detection platform surface of the detection bracket 103 have parallelism technical requirements. It is designed and manufactured in accordance with the inspection fixture standards and the technical requirements of the motor vehicle installation interface.

[0037] The outer edge of the detection flange 101 is designed with a mounting hole for N1-S detection. The mounting hole for N1-S detection has technical requirements for position and angle relative to the center line of the inner stop 105 and is designed and manufactured in accordance with the inspection fixture standards and the technical requirements for motor vehicle installation interfaces.

[0038] The detection bracket 103 is designed to have an H1 symmetrical detection platform surface, which is designed and manufactured according to the acceptance accuracy level 1 of GB / T22095 "Cast Iron Platform".

[0039] The detection bracket 103 is designed to have an H1 symmetrical detection platform surface, and the N2-K and c and b mounting hole distance dimensions are designed on the H1 symmetrical detection platform surface. Its dimensional tolerance and position tolerance are designed and manufactured in accordance with the installation fixture standards and motor vehicle installation interface technical requirements.

[0040] The detection flange 101 is connected to the detection bracket 103 through the reinforcing plate 102 to form a whole, thereby enhancing the strength, rigidity and stability of the detection flange 11 and the detection bracket 13 as a whole.

[0041] The detection flange 101 and the detection bracket 103 are connected into one body through the detection system support base plate 104, which supports and ensures the strength, rigidity and stability of the detection flange 101 and the detection bracket 103 as a whole.

[0042] By optimizing the design of the detection system support base plate 104 and the reinforcement plate 102, the detection flange 101 and the detection bracket 13 are doubled and reinforced into one, thereby improving the overall strength, rigidity and stability of the positioning detection seat.

[0043] The open slots 106 designed on the bottom of the detection system support base plate 104 and the detection flange 101 will facilitate the installation and removal of the small bolts 3 and nuts 4 and the traction motor 5.

[0044] The two sides of the detection bracket 103 are designed to be partially transparent circular holes, which facilitates observation of the actual conditions of the large bolt 2 and the traction motor 5 during detection.

[0045] The large bolts 2 are standard bolts used and installed in actual working conditions, which can accurately detect and ensure the authenticity and reliability of the traction motor 5 during use.

[0046] The small bolts 3 and nuts 4 are standard bolts used and installed in actual working conditions, which can accurately detect and ensure the authenticity and reliability of the traction motor 5 during use.

[0047] The traction motor 5 uses the motor vehicle traction motor required by the customer's order technical conditions.

[0048] The detection workflow is as follows: the positioning detection seat is fixed into one piece by the small bolts 3 and nuts 4 through the inner stop 105 of the positioning detection seat and the traction motor 5 and the mounting hole N1-S. The inner stop 105 on the positioning detection seat and the mounting hole N1-S can solve the problem of whether the size deviation, position deviation and angle deviation of the outer stop of the mounting interface of the traction motor 5 and the mounting hole N1-S meet and reach the tolerance range required by the drawing.

[0049] The symmetrical N2-K holes on the H1 symmetrical foot surface of the positioning detection seat are connected to the symmetrical N2-K holes on the H symmetrical foot surface of the traction motor 5 through large bolts 2, which can solve the problem of whether the dimension c deviation and dimension b deviation from the vertical plane of the outer stop of the mounting interface of the traction motor 5 to the center of the foot hole N2-K mounting hole and the foot hole N2-K position deviation meet and meet the tolerance range required by the drawing.

[0050] A measurement gap H2 is reserved and designed between the H1 symmetrical foot surface of the positioning detection seat and the H symmetrical foot surface of the traction motor 5. The actual size of H1 is measured and known through the designed and manufactured positioning detection seat, and the qualified size interval and range of H is known and known through the design drawings. In this way, based on the known H and H1 sizes, a set of 0.01mm precision detection feeler gauges within the size range of 0 to (1+H2) are selected; the reserved measurement gap H2 is measured multiple times around the circumference using the feeler gauge, and the actual arithmetic average value of H2 is obtained by conversion, and the arithmetic average value H2 = ∑H2n measured size / n is calculated, and recorded in real time according to the detection sequence.

[0051] After conversion one: the measured value of H is converted through H=H1-H2, and by comparing the measured value of H with the tolerance range of the technical requirements of the H design in the product drawing, it is possible to solve the problem of whether the height H dimensional deviation from the H-symmetrical base plane of the traction motor 5 installation interface to the traction motor rotation center meets and meets the tolerance range required by the drawing.

[0052] After conversion 2: by recording the difference between the maximum and minimum values ​​of the H2 measured value in real time according to the detection sequence, it is possible to solve the problem of whether the flatness deviation of the H-symmetrical base plane of the traction motor 5 installation interface meets and reaches the tolerance range required by the drawing.

[0053] The measuring instruments used in the above tests are all known in the prior art and are purchased parts, including but not limited to 90° bend rulers, height vernier calipers, rulers, inside micrometers, outside micrometers, vernier calipers, feeler gauges and other testing measuring instruments, which can be obtained through measurement, recording, calculation and conversion. In order to facilitate the calculation, a calculator can be used for assistance, or Excel tables can be used for auxiliary statistical calculations.

[0054] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
