Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile part detection, in particular to an automobile glass size detection fixture. BACKGROUND

[0002] With the rapid development of the automobile industry, automobile glass, as an important component of automobiles, its quality and dimensional accuracy have a crucial influence on the overall performance and safety of the automobile. Automobile glass not only needs to meet the requirements of optical performance, but also needs to achieve extremely high standards in dimensional accuracy to ensure its correct installation and sealing on the automobile body. Therefore, the dimensional detection of automobile glass is an indispensable link in the production process of automobile parts.

[0003] At present, the dimensional detection of automobile glass mainly relies on special fixtures. However, the existing automobile glass size detection fixtures have certain limitations in design and function. For example, Chinese patent application "A detection equipment for automobile glass sunroof", publication number: CN108801118A, discloses a detection equipment for automobile glass sunroof, which includes a tooling rack, a sliding block feeding mechanism, a pneumatic cylinder lifting mechanism and a detection mechanism. The feeding mechanism and the lifting mechanism are arranged on the tooling rack, and the detection mechanism is arranged on the top of the tooling rack. The sliding block feeding mechanism slides on the sliding rail through the sliding block to install the glass sunroof on the tooling rack. The pneumatic cylinder lifting mechanism lifts the glass sunroof on the tooling rack. The detection mechanism detects the glass sunroof through a Bluetooth dial gauge. Although the detection equipment of the above-mentioned patent application improves the detection efficiency to a certain extent, the whole equipment structure is complex and the cost is high.

[0004] Another Chinese patent application "High-precision fixture for automobile sunroof glass", publication number: CN208968516U, discloses a high-precision fixture for automobile sunroof glass, which includes a bottom plate, a plurality of detection blocks are fixedly arranged on the bottom plate, the detection blocks are arranged to form a detection part, a plurality of supports for placing positioning pins are arranged on the outer side of the detection blocks, the supports are fixed on the bottom plate, a plurality of through holes are arranged on the outer side edges of the detection blocks, a plurality of table seats are fixedly arranged on the bottom plate in the middle of the detection part, a through hole is arranged on each table seat, the through hole penetrates to the bottom of the bottom plate, and a full-automatic detection device is arranged in each through hole; a plurality of clamping plate seats are symmetrically arranged on the bottom plate around the outer side of the detection blocks, a clamping plate is arranged on each pair of clamping plate seats, the clamping plate is arranged above the detection part, and a connecting plate is fixedly arranged at both ends of the clamping plate.

[0005] The fixtures in the prior art mostly adopt a local detection method, which only measures the specific area or part of the glass, and cannot comprehensively and accurately reflect the overall size condition of the glass. This local detection method often fails to meet the actual production requirements when facing complex glass shapes and high precision requirements. Moreover, the operation process of the existing fixtures is relatively complicated, which needs manual adjustment and positioning multiple times, thereby increasing the labor intensity and reducing the detection efficiency. Utility model content

[0006] The technical problem to be solved by the present application is to provide an automobile glass size gauge capable of realizing rapid and stable installation of the glass.

[0007] The technical scheme adopted by the present application is as follows: an automobile glass size gauge comprises a base plate, wherein an installation seat and a plurality of positioning seats are arranged on the base plate, the installation seat is an outer frame structure, the top surface of the installation seat is in a closed graphic structure, the positioning seats are located in the installation seat, positioning shafts are arranged on the positioning seats and protrude from the top surface of the installation seat, the top surface of the installation seat is provided with an embedded surface and an outer reference surface, the outer reference surface and the embedded surface form a stepped surface, installation base points are protrudingly arranged on the outer reference surface, and positioning latches are arranged on the outer periphery of the outer reference surface.

[0008] Compared with the prior art, the present application has the following advantages: first, the present application is provided with multiple positioning structures, the protruding installation base points of the outer reference surface can be used as auxiliary calibration points to ensure the alignment consistency of the gauge and the standard part. The positioning shafts protruding from the top surface of the installation seat cooperate with the pre-positioning holes of the glass to realize rapid positioning in the X / Y axis direction. The positioning latches on the outer periphery can fix the gauge and the external platform of the glass to be detected, thereby reducing vibration interference and improving measurement stability.

[0009] Secondly, the installation seat of the present application adopts an outer frame closed graphic structure, and the top surface thereof completely covers the edge contour of the glass, so that the overall contour precision can be directly detected by the adhesion between the frame and the edge of the glass, thereby solving the limitation of the partial detection of the prior art and reflecting the overall size deviation of the glass at one time.

[0010] Thirdly, the stepped surface structure formed by the embedded surface and the outer reference surface not only realizes the edge embedding positioning of the glass (embedded surface), but also provides the outer reference surface as a measurement reference plane. The layered design also naturally forms a vertical direction limiting after the glass is installed, thereby avoiding displacement during the measurement process and improving the detection accuracy.

[0011] In some embodiments of the present application, the embedded surface is concavely arranged inside the outer reference surface, and the connection surface between the embedded surface and the outer reference surface constitutes a reference contour surface.

[0012] The glass installed at the embedded surface can be detected by detecting whether the gap between the outer contour of the glass and the reference contour surface meets the detection standard, thereby realizing the detection of the contour of the glass. Specifically, the gap between the edge of the glass and the reference contour surface can be directly measured by a plug gauge or an optical means, and the contour deviation is converted into a quantifiable value, thereby improving the detection accuracy.

[0013] In some embodiments of the present application, an opening is arranged in the top surface of the mounting base, and the positioning shaft is embedded in the opening or the inner surface.

[0014] The opening design allows the positioning shaft to pass out from different positions (such as the opening or the inner embedded surface), which can adapt to the positioning hole distribution requirements of different glass models and enhance the versatility of the testing tool.

[0015] In some embodiments of the present application, a through hole is arranged on the inner embedded surface, the position of the through hole is adapted to the position of the positioning shaft, the positioning shaft passing out from the through hole is coaxially arranged with the through hole, and the inner diameter of the through hole is larger than the outer diameter of the positioning shaft.

[0016] Firstly, the design that the inner diameter of the through hole is larger than the outer diameter of the positioning shaft allows the positioning shaft to have a slight radial deviation, which can avoid the jamming problem caused by the glass or the testing tool processing tolerance. Secondly, the positioning shaft can be designed to be movable, which can be automatically adjusted to the center position by gravity or slight pressure during the glass placement process, thereby simplifying the manual alignment operation.

[0017] In some embodiments of the present application, the through hole is provided with a plug cap, the plug cap includes a cap head and a plug rod, the outer diameter of the plug rod is smaller than the outer diameter of the cap head, the outer diameter of the plug rod matches the inner diameter of the through hole, and grooves are arranged on the opposite sides of the plug rod. The positioning shaft located in the plug cap can be observed through the grooves.

[0018] The cap head design of the plug cap facilitates manual plugging and unplugging, and the switching between the through hole blocking and opening states of the plug rod can be completed without tools, thereby improving the operation convenience. The cooperation state of the positioning shaft and the glass positioning hole can be directly observed through the grooves, which ensures that the positioning shaft is completely inserted into the hole and avoids the detection error caused by the virtual position.

[0019] In some embodiments of the present application, mounting base points are arranged at the corners of the outer reference surface, and the mounting base points are semi-circular convex structures.

[0020] The glass outer frame to be detected is mounted through the mounting base points, which can effectively ensure the accuracy of the mounting. The semi-circular convex contact area is small, which reduces the friction loss between the glass and the base points and maintains the positioning accuracy during long-term use.

[0021] In some embodiments of the present application, the outer reference surface extends outwardly by a plurality of extension blocks, the extension blocks are provided with positioning holes, and the positioning holes are provided with positioning pins.

[0022] The arrangement of the positioning holes and the positioning pins realizes the positioning of the glass outer frame. In the present application, the extension blocks can be independently processed and assembled to the outer reference surface, which facilitates the increase or decrease of the number of fixing points according to the detection requirements and reduces the overall structural modification cost.

[0023] In some embodiments of the present application, the outer reference surface is in a trapezoidal structure as a whole, and two adjacent sides of the outer reference surface are provided with extension blocks.

[0024] In some embodiments of the present application, one side of the outer reference surface is provided with a reference seat, and a reference block is movably mounted on the reference seat, and the distance between the reference block and the mounting seat can be adjusted by operating the reference block.

[0025] The adjustable reference block allows fine adjustment of the detection reference according to the actual size of the glass, adapts to the size fluctuation of different batches or models of glass, and improves the adaptability of the gauge. In addition, the change of environmental temperature may cause the size of the gauge or the glass to change, and the thermal expansion error can be compensated in real time by adjusting the reference block to ensure the consistency of the detection results.

[0026] In some embodiments of the present application, a threaded hole is formed in the reference seat, and the reference block is connected with the threaded hole through a screw rod, and the distance between the reference block and the mounting seat can be adjusted by rotating the screw rod.

[0027] The threaded cooperation has self-locking characteristics, and after adjustment, the position of the reference block can be fixed without additional locking device to prevent the reference from deviating during detection. The threaded transmission can provide high-precision displacement control to realize fine adjustment of the position of the reference block and meet the high-precision detection requirement.
