Description

Technical Field

[0001] This utility model belongs to the field of water pump inspection tool technology. Specifically, this utility model relates to a comprehensive position measurement tool for a water pump assembly. Background Technology

[0002] Water pumps are mainly installed inside cars, specifically in the engine block. There are multiple water channels for cooling water circulation, which are connected to the radiator (commonly known as the water tank) located at the front of the car through water pipes, forming a large water circulation system. A water pump is installed at the upper outlet of the engine, which is driven by the fan belt to pump the hot water out of the engine block water channels and pump the cold water in.

[0003] Centrifugal water pumps are widely used in automobile engines. Their basic structure consists of parts such as the water pump housing, connecting plate or pulley, water pump shaft and bearing or shaft-connected bearing, water pump impeller and water seal device, and is a major component of automobiles.

[0004] Existing inspection tools for water pumps are mostly designed for a single positional parameter, requiring multiple clamping and tool switching, which is inefficient and results in large cumulative errors. Utility Model Content

[0017] Preferably, the first detection mechanism includes a first mounting block fixedly installed on the base and a spring detection pin J that passes through the first mounting block.

[0018] Preferably, the second detection mechanism includes mounting blocks A, B, and C, which are fixedly mounted on the base and arranged in a triangular pattern. Spring detection pins J and J' are provided through the mounting blocks A, B, and C.

In the past, the inspection work required high professional skills from the operators, and it was necessary to undergo a long period of training to master the inspection techniques. However, this inspection tool effectively reduces the difficulty of manual operation, thereby reducing labor costs. According to calculations, after adopting the new inspection tool, labor costs can be reduced by about 30%, bringing significant economic benefits to enterprises. Attached Figure Description

[0032] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of this utility model, and to facilitate its implementation.

[0033] Specifically, such as Figures 1 to 5 As shown, a comprehensive position gauge for a water pump assembly includes a base 1, and further includes:

[0034] The detection support plate 2 is installed at the center of the top of the base 1;

[0035] A flipping mechanism 3 is installed on the top of the base 1 and located on the left side of the detection support plate 2;

[0036] The first detection mechanism 4 is installed on the top of the base 1 and is fitted to the flipping mechanism 3.

[0037] The second detection mechanism 5 is installed on the top of the base 1 and located on the rear side of the detection support plate 2;

[0038] The first reference detection structure 6 is installed on the top of the base 1 and located on the front side of the detection support plate 2.

[0039] The second reference detection structure 7 is installed on the top of the base 1 and is located to the right of the first reference detection structure 6;

[0040] Clamp A8 is mounted on the top of the base 1 and located on the right side of the detection support plate 2;

[0041] Clamp B9, the clamp A9 is mounted on the top of the base 1 and located behind the flipping mechanism 3.

[0042] It should be noted that the detection method of this solution only requires placing the water pump assembly on the detection support plate 2 at the corresponding position, and then it can be detected by the first reference detection structure 6 and the second reference detection structure 7, and then detected by the flipping mechanism 3, the first detection mechanism 4 and the second detection mechanism 5 in sequence.

[0043] In addition, this solution can simultaneously detect the orifice size, orifice position, and surface clearance of the water pump assembly, significantly reducing the time for a complete test to less than 10 minutes and improving the testing efficiency by at least 66%. At the same time, thanks to the synergistic effect of modularization and multi-dimensional testing, the testing accuracy has been improved from ±0.1mm in the traditional method to ±0.05mm, greatly enhancing the product quality control capability.

[0044] The detection support plate 2 is respectively equipped with positioning pin B, positioning pin C, detection pin J1 and detection pin J2.

[0045] It should be noted that in actual operation, when using this water pump assembly comprehensive position gauge, the product to be tested must be carefully aligned with the locating pins B and C specifically set on the gauge. The product is then placed on the testing support plate 2, and clamps A8 and B9 are clamped in sequence according to the pre-set order. Clamps A8 and B9 cooperate with the testing support plate 2, locating pins B and C, and base 1 to apply force to the product from multiple directions, firmly fixing the product on the gauge. This ensures that the product maintains a stable position during subsequent testing, avoiding the impact of displacement or other factors on the accuracy of the test results. This lays a solid foundation for accurately testing key position parameters such as the water pump flange end face, shaft hole, and bolt hole.

[0046] The flipping mechanism 3 includes a base block 31 fixedly installed on the base 1, a flip plate 32 rotatably connected to the base block 31, and spring detection pins J7 and J8 disposed through the front end of the flip plate 32.

[0047] The first detection mechanism 4 includes a first mounting block 41 fixedly installed on the base 1 and a spring detection pin J9 that passes through the first mounting block.

Spring detection pins J3 and J4 are provided through the mounting block A551, spring detection pin J5 is provided through the mounting block B52, and spring detection pin J6 is provided through the mounting block C53.

[0049] It should be noted that after completing the above work, the inspection begins. The flipping mechanism is closed, and then the spring detection pins J7 and J8 are pushed in the product direction. If they can be inserted, it is qualified; otherwise, it is unqualified. Then, the spring detection pins J3-J6 and J9 are pushed in. If they can be inserted, it is qualified; otherwise, it is unqualified.

[0050] The first reference detection structure 6 includes a first mounting base 61 fixedly installed on the base 1, and a detection pin J11 is inserted into the first mounting base 61.

[0051] The second reference detection structure 7 includes a second mounting base 71 fixedly installed on the base 1, and a detection pin J12 is inserted into the first mounting base 71.

[0052] It should be noted that the detection pins J11 and J12, along with the aforementioned detection pins J1 and J2, are preliminary detection pins. If they can be inserted simultaneously with positioning pins B and C when the product is placed, it is considered qualified and can proceed to the next step of testing. If they cannot be inserted, it is considered unqualified.

[0053] Reference key I, reference key II and reference key III are respectively installed at the corners of the base 1. Handles 10 are installed on both sides of the base 1 in a staggered manner. A no-go gauge 11 is set on the base 1 by a snap fastener.

[0054] It should be noted that the go / no-go gauge 11 with a diameter of φ4.8+φ5.2 is used to check the clearance between the pressure feet at J11 and J12. If the go gauge can pass smoothly through the no-go gauge, it is considered qualified; otherwise, it is unqualified.

[0055] In addition, the reference datum for this fixture is as follows: the upper plane and hole center of reference key I (X:258.437 Y:190.266 Z:-168.414), reference key II (X:-71.563 Y:190.266 Z:-168.414), and reference key III (X:258.437 Y:-109.713 Z:-164.822) are used as the fixture calibration (inspection) datum. The inner diameter of the datum is φ10H7, and the surface quality requirement is Ra0.8. The tolerance requirement for the datum surface is ±0.05mm, the positional tolerance of the datum hole is ±0.03mm, the relative positional tolerance of the datum hole is ±0.03mm, and the parallelism and perpendicularity of the datum surface are <0.05 / 1000.

[0056] Fixture accuracy: Position tolerance of positioning holes: ±0.03 mm; Accuracy of reference surface and support surface: ±0.05 mm; Position tolerance of detection holes: ±0.05 mm; Other surfaces: ±0.1 mm; All pin holes are required to have a H7 / g6 fit.

[0058] During the actual operation process, when using this comprehensive position gauge for the water pump assembly, the product to be detected needs to be carefully aligned with the specifically set positioning pins B and C on the fixture, and the product is placed on the detection support plate 2. The detection pins J11 and J12, along with the above-mentioned detection pins J1 and J2, are preliminary detection pins. If the product can be inserted into both the positioning pins B and C simultaneously when placed, it is considered qualified and the next step of detection can be carried out; if it cannot be inserted, it is unqualified. Then, in accordance with the pre-set order, the clamping actions are performed on the clamp A8 and the clamp B9 in sequence. The clamp A8 and the clamp B9 cooperate with the detection support plate 2, the positioning pins B and C, and the base 1 to exert forces on the product from multiple directions, firmly fixing the product on the fixture to ensure that the product always maintains a stable position during the subsequent detection process.
