[0002] In the automotive manufacturing industry, dimensional deviation measurement of automotive parts is used to identify problems in the production process, ensure that parts meet design requirements, and thus improve the performance and safety of the entire vehicle. Currently, most of the fixtures used for dimensional deviation measurement of automotive parts are specialized fixtures. This is because different automotive parts vary in shape, size, number and location of locating holes and locating surfaces. To achieve precise positioning and measurement, it is often necessary to design and manufacture specialized fixtures for each specific part.

[0003] However, this clamping method has many problems. The mold-making process involves design and processing technology, requiring investment of manpower, resources, and time. From drawing mold design drawings to selecting materials and manufacturing, and then to debugging and correction, each step requires the support of professional technicians and high-precision equipment, which increases the inspection cost of automotive parts. In addition, automotive products are updated and replaced at an accelerated pace, and new automotive parts are constantly emerging. If a new mold is made and a special fixture is manufactured for each new part, the cost is high, and the fixture manufacturing cycle may affect the development and production schedule of new products.

The embodiments of this utility model will now be described based on its overall structure.

[0025] Example 1 As shown in the figure, an automotive parts inspection and positioning device includes a support platform, support feet, a first translation device, a second translation device, a vertical movement device, and a positioning fixture. A first translation device is installed on the top surface of the support platform; a second translation device is installed on the top surface of the first translation device; a vertical moving device is installed on the top surface of the second translation device; and a positioning clamp is installed at the top of the vertical moving device.

[0026] Next, the working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model: The support platform provides support, and the positioning plate is used to install the first translation device; the first and second translation devices are used to move the positioning fixture, and the first and second translation devices respectively provide longitudinal and lateral translation movements; the vertical movement device is used to provide vertical movement; the positioning fixture is used to fix the automotive parts to be inspected.

[0027] During operation, a corresponding number of positioning fixtures are selected based on the number and position of the positioning holes and positioning surfaces of the automotive parts to be inspected. Next, a first translation device is installed on the top surface of the positioning plate, and a second translation device is installed on the top surface of the first translation device. A vertical movement device is then installed on the top surface of the second translation device. A positioning fixture is installed on the top surface of the vertical movement device. After installation, the first translation device moves the second translation device, which in turn moves the vertical movement device, which in turn moves the positioning fixture. The position of the positioning fixture is adjusted, and finally, the automotive parts to be inspected are installed onto the adjusted positioning fixture, thus completing the positioning of the automotive parts.

[0028] Example 2 The difference between this embodiment and Embodiment 1 is that the first translation device includes a first slider, a first guide rail mounting base, a first translation guide rail, and a support base plate; the support base plate is detachably mounted on the top surface of the support platform; the bottom surface of the first guide rail mounting base is detachably mounted on the top surface of the support base plate; the first guide rail is mounted on the top surface of the first guide rail mounting base; the lower end of the first slider is connected to the first guide rail, and the upper end is mounted with a second translation device.

[0029] The support base plate is detachably mounted on the top surface of the support platform, providing stable support for the entire first translation device. The first guide rail mounting seat connects the support base plate and the first guide rail, ensuring the stable installation of the first guide rail. Its detachable connection facilitates replacement or maintenance of the first guide rail. During operation, the support base plate is installed on the top surface of the support platform, followed by the sequential installation of the first guide rail mounting seat, the first guide rail, and the first slider. The first slider slides on the first guide rail, moving the second translation device mounted on its upper end to the appropriate position.

[0030] The working principle of this embodiment is the same as that of Embodiment 1.

[0031] Example 3 The difference between this embodiment and embodiment 2 is that the second translation device includes a second guide rail and a second slider; the second guide rail is horizontally arranged and its bottom surface is connected to the upper end of the first slider; the lower end of the second slider is connected to the second guide rail and a vertical moving device is installed on its upper end.

[0032] The second guide rail provides a sliding track for the second slider, enabling lateral position adjustment of the vertical moving device mounted on it. During operation, the first translation device drives the second translation device to move. Subsequently, the second slider slides on the second guide rail, further adjusting the lateral position of the vertical moving device and the positioning fixture.

[0033] The working principle of this embodiment is the same as that of Embodiment 1.

[0034] Example 4 The difference between this embodiment and embodiment 3 is that the vertical moving device includes a clamp support rod, a first mounting base, and a servo electric cylinder; the clamp support rod is vertically arranged, with its lower end connected to the top surface of the second slider, and the servo electric cylinder is mounted on its side; the lower end of the first mounting base is connected to the output end of the servo electric cylinder, and the upper end is equipped with a positioning clamp.

[0035] The clamp support rod supports the servo electric cylinder, the first positioning component, and the second positioning component. The servo electric cylinder drives the first mounting base to move up and down, thereby adjusting the vertical position of the first and second positioning components to accommodate the positioning needs of automotive parts of different heights and dimensions.

[0036] When positioning automotive parts, after lateral position adjustment, the servo electric cylinder is activated, which extends and retracts to move the first mounting base up and down, thereby moving the first and second positioning components to the appropriate vertical position. Then, the positioning components engage with the positioning holes and surfaces of the automotive parts to complete the vertical positioning of the automotive parts.

[0037] The working principle of this embodiment is the same as that of Embodiment 1.

[0038] Example 5 The difference between this embodiment and embodiment 4 is that the positioning fixture includes a first positioning component, a second positioning component, a transverse connecting plate, and a longitudinal connecting plate; the longitudinal connecting plate is vertically disposed on the side of the first mounting base, extending downward at its lower end and with the first positioning component mounted on its upper end; the transverse connecting plate is horizontally disposed, with one end connected to the lower end of the second positioning component and the other end connected to the upper end of the longitudinal connecting plate. The transverse connecting plate is used to connect the first positioning component and the longitudinal connecting plate.

[0039] The working principle of this embodiment is the same as that of Embodiment 1.

[0040] Example 6 The difference between this embodiment and embodiment 5 is that the first positioning component includes a second mounting base, a connecting rod, and a pressure block; the lower end of the second mounting base is connected to the upper end of the longitudinal connecting plate; one end of the connecting rod is hinged to the upper end of the second mounting base, and the other end is fitted with a pressure block.

[0041] The second mounting base connects at its lower end to the upper end of the longitudinal connecting plate, serving to connect the longitudinal connecting plate and the connecting rod, and transmitting the vertical movement from the longitudinal connecting plate to the connecting rod. The connecting rod is hinged, allowing it to rotate and thus adjust the angle and position of the pressure block. The pressure block, mounted on the other end of the connecting rod, mates with the positioning holes or surfaces of the automotive parts. By rotating the connecting rod, the pressure block is pressed against the opposite side of the second positioning assembly, achieving positioning and clamping of the automotive parts.

[0042] The working principle of this embodiment is the same as that of Embodiment 1.

[0043] Example 7 The difference between this embodiment and embodiment 6 is that the second positioning component includes a positioning rod seat, a positioning pin, and a positioning surface; the lower end of the positioning rod seat is connected to the first mounting base, and the upper end is fitted with the positioning pin; the positioning surface is mounted on the positioning pin through a hole pin.

[0044] The positioning rod seat provides a mounting base for the positioning pin. The positioning surface is mounted on the positioning pin via a pin-hole engagement, and the positioning surface is used to mate with the positioning surface of the automotive part. During operation, the positioning pin is inserted into the positioning hole of the automotive part to complete the initial positioning. The positioning surface is mounted on the positioning pin via the pin-hole engagement, connecting with the positioning surface of the automotive part, and can be adjusted according to the shape and position of the positioning surface of the automotive part.

[0045] The working principle of this embodiment is the same as that of Embodiment 1.

[0046] Example 8 The difference between this embodiment and Embodiment 7 is that the positioning surface is a positioning block, with a cylindrical lower end, a conical middle section, and a hemispherical upper end. The cylindrical lower end of the positioning surface can be stably inserted into the positioning hole of the automotive part, providing stable support and initial positioning. The conical middle section acts as a guide, facilitating smooth insertion of the positioning block into the positioning hole. The hemispherical upper end prevents excessive pressure on the surface of the automotive part, reducing damage to the part's surface, and can also adapt to positioning surfaces of different shapes.

[0047] The working principle of this embodiment is the same as that of Embodiment 1.

[0048] In summary, this utility model, through the coordinated operation of a support platform, a positioning plate, a first translation device, a second translation device, a vertical movement device, and positioning fixtures, can flexibly select the corresponding number of fixtures according to the number and position of the positioning holes and positioning surfaces of the automotive parts to be inspected. It can position and clamp automotive parts of different shapes and sizes, adapting to the positioning needs of various automotive parts of different specifications. It eliminates the need to manufacture special fixtures for each part separately, reducing the cost of measuring the dimensional deviation of automotive parts.

[0049] The device comprises a first translation device, a second translation device, and a vertical movement device, which move and adjust the position of the positioning fixture to meet the diverse positioning requirements of different parts. The positioning pins on the positioning rod are installed using a pin-and-hole fit, allowing for the selection of different pin specifications based on the positioning hole size of different parts.
