Description

Technical Field

[0001] This utility model relates to the field of product testing technology, specifically a simple combined gauge for measuring flatness and position. Background Technology

[0002] Inspection fixtures are specialized tools used in industrial production to quickly inspect parameters such as dimensions and geometric tolerances of parts. They mainly serve mass production scenarios. Through customized design, inspection fixtures integrate positioning, clamping, and measuring elements, which can quickly determine whether parts meet the drawing requirements, greatly improve inspection efficiency, and reduce reliance on operator skills. They are widely used in the automotive, aerospace, and precision machinery industries.

[0003] However, existing inspection tools often only perform single inspections, such as flatness inspection or positional inspection, without combining the two. In actual operation, a product part needs to undergo two inspection processes, which takes a long time. This does not effectively reduce the time spent on inspection, does not improve inspection efficiency, and has poor practicality. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a simple combined gauge for measuring flatness and position to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a simple combined gauge for measuring flatness and position, comprising a base, a lower support plate, an upper support plate, and four connecting columns symmetrically distributed between the lower and upper support plates. A position detection column is fixedly installed at the top of the upper support plate. A product body is placed on the upper part of the upper support plate. Ear seats are provided on both sides of the product body. A reserved hole adapted to the position detection column is opened on the outer side of the ear seat. A micrometer fixing fixture assembly is provided at the lower part of the upper support plate. A micrometer sensor is fixedly installed below the upper support plate through the micrometer fixing fixture assembly. A PIN pin is provided on the upper part of the micrometer sensor. A through hole adapted to the PIN pin is opened at the top of the upper support plate.

[0006] Preferably, the micrometer fixing fixture assembly includes a fixing base, a fixing bolt is provided between the fixing base and the upper support plate, a clamping plate one and a clamping plate two are fixedly installed on the outer side of the fixing base, clamping holes are provided on the opposite surfaces of the clamping plate one and the clamping plate two, and a locking bolt is provided between the clamping plate one and the clamping plate two.

[0007] The above technical solution allows the micrometer sensor to be securely installed under the upper support plate, and the clamping tightness of clamping plate one and clamping plate two can be flexibly adjusted by locking bolts, which facilitates the disassembly, assembly, and position calibration of the micrometer sensor.

[0008] Preferably, the first clamp and the second clamp have the same specifications, the cross-section of the clamping hole is C-shaped, and the fixing seat together with the first clamp and the second clamp form a tuning fork-type structure.

[0009] The above technical solution, with its symmetrical clamping plate structure and C-shaped clamping holes, can clamp the micrometer sensor, reducing difficulty and improving assembly efficiency.

[0010] Preferably, four identical position detection columns are provided, and the four position detection columns are symmetrically distributed about the vertical axis of the upper support plate.

[0011] Through the above technical solution, the four symmetrically distributed position measurement columns can be precisely matched with the reserved holes of the product ear seat. The reserved holes can be inserted into the position measurement columns, and the reserved holes on the outside of the product body can be judged to be qualified.

[0012] Preferably, the micrometer fixing fixture assembly, the micrometer sensor, and the PIN pin are all provided with a plurality of identical ones, the PIN pin passing through the through hole and extending into the interior of the product body, and the PIN pin contacting the interior of the product body.

[0013] Through the above technical solution, several pins can contact different positions on the product body respectively, and in conjunction with the micrometer sensor, multi-point synchronous measurement can be achieved, which can detect the flatness and positional deviation of the product and improve the integrity and accuracy of the measurement results.

[0014] Preferably, the front side of the base is provided with a display, a first indicator light, and a second indicator light.

[0015] Through the above technical solution, the display can intuitively show the measurement data of the micrometer sensor, and the first and second indicator lights can quickly provide feedback on whether the product is qualified, making it easier for operators to make quick judgments and improving testing efficiency.

[0016] Compared with the prior art, this utility model provides a simple combined gauge for measuring flatness and position, which has the following advantages:

[0017] 1. This simple flatness and position measurement fixture features a micrometer fixing assembly that securely mounts the micrometer sensor. The clamping tightness can be flexibly adjusted via locking bolts, facilitating sensor disassembly, assembly, and position calibration. The symmetrical clamping plate structure with C-shaped clamping holes reduces the difficulty of clamping the micrometer sensor and improves assembly efficiency. Four symmetrically distributed position measurement pins precisely match the pre-drilled holes on the product's mounting base, allowing for quick determination of hole quality simply by inserting the pins. Operation is intuitive and simple. Multiple pins work with the micrometer sensor to achieve simultaneous multi-point measurement, detecting flatness and position deviations of the product, improving the completeness and accuracy of measurement results. The fixture is rationally designed, easy to operate, and can quickly complete the inspection process, significantly reducing inspection time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] like Figure 1-7 As shown, this utility model provides a simple combined gauge for measuring flatness and position, including a base 1, a lower support plate 2, an upper support plate 4, and four connecting columns 3 symmetrically distributed between the lower support plate 2 and the upper support plate 4. A position detection column 6 is fixedly installed at the top of the upper support plate 4. A product body 5 is placed on the upper part of the upper support plate 4. Ear seats 501 are provided on both sides of the product body 5. A reserved hole 502 adapted to the position detection column 6 is opened on the outer side of the ear seat 501. A micrometer fixing fixture assembly 7 is provided at the lower part of the upper support plate 4. A micrometer sensor 8 is fixedly installed below the upper support plate 4 through the micrometer fixing fixture assembly 7. A PIN pin 9 is provided on the upper part of the micrometer sensor 8. A through hole 10 adapted to the PIN pin 9 is opened at the top of the upper support plate 4.

[0029] Example 2:

[0030] like Figure 2-7 As shown, as an improvement to the previous embodiment, the micrometer sensor 8 is installed and fixed in a way that facilitates the installation.

[0031] Specifically, the micrometer fixing fixture assembly 7 includes a fixing base 701, a fixing bolt 702 between the fixing base 701 and the upper support plate 4, and a clamping plate 703 and a clamping plate 704 fixedly installed on the outer side of the fixing base 701. Clamping holes 706 are provided on the opposite surfaces of clamping plates 703 and 704, and a locking bolt 705 is provided between clamping plates 703 and 704. The advantage is that it can stably install the micrometer sensor 8 below the upper support plate 4, and the clamping tightness of clamping plates 703 and 704 can be flexibly adjusted by the locking bolt 705, facilitating the disassembly, assembly, and position calibration of the micrometer sensor 8.

[0032] Specifically, clamping plate 703 and clamping plate 704 have the same specifications, and the cross-section of clamping hole 706 is C-shaped. The fixing base 701, together with clamping plate 703 and clamping plate 704, forms a tuning fork-type structure. The advantage is that the symmetrical clamping plate structure, combined with the C-shaped clamping hole 706, can clamp the micrometer sensor 8, reducing the difficulty and improving assembly efficiency.

[0033] Example 3:

[0034] like Figure 2-7 As shown, as an improvement to the previous embodiment, in order to detect the qualification of the reserved hole 502 on the outer ear seat 501 of the product body 5.

[0035] Specifically, four identical position detection columns 6 are provided, and the four position detection columns 6 are symmetrically distributed about the vertical axis of the upper support plate 4. The advantage is that the four symmetrically distributed position detection columns 6 can precisely match the reserved holes 502 of the product ear seat 501. By inserting the reserved holes 502 into the position detection columns 6, it can be determined that the reserved holes 502 on the outer side of the product body 5 are qualified.

[0036] Specifically, the micrometer fixing fixture assembly 7, the micrometer sensor 8, and the PIN pins 9 are all provided with several identical ones. The PIN pins 9 pass through the through hole 10 and extend into the interior of the product body 5, making contact with the interior of the product body 5. The advantage is that several PIN pins can contact different positions on the product body 5 respectively, and in conjunction with the micrometer sensor 8, multi-point synchronous measurement can be achieved, which can detect the flatness and positional deviation of the product, and improve the completeness and accuracy of the measurement results.

[0037] Specifically, the front of the base 1 is equipped with a display 11, a first indicator light 12, and a second indicator light 13. The advantage is that the display 11 can intuitively display the measurement data of the micrometer sensor 8, and the first and second indicator lights 12 and 13 can quickly provide feedback on whether the product is qualified, facilitating quick judgment by operators and improving testing efficiency.

[0038] Working principle: During use, the operator aligns the reserved hole 502 on the outer ear seat 501 of the product body 5 with the position detection column 6 and inserts it. If the reserved hole 502 can be inserted into the position detection column 6, the reserved hole 502 can be judged. If the reserved hole 502 on the product body 5 is qualified, the PIN pin 9 located on the upper part of the micrometer sensor 8 can detect the inside of the product body 5 and detect the flatness inside the product body 5. If the test is qualified, the first indicator light 12 and the second indicator light 13 can quickly provide feedback on whether the product is qualified, which is convenient for operators to make quick judgments and improve detection efficiency. The overall design is reasonable and the operation is simple.
