Description

Technical Field

[0001] This utility model relates to the field of adjustable diameter gauges, specifically an adjustable diameter gauge. Background Technology

[0002] In the field of machining, rapid and accurate inspection of the diameter of workpieces such as shafts and holes is a crucial step in ensuring product quality. Currently, commonly used diameter measuring tools such as calipers and micrometers, while versatile, suffer from problems such as large subjective errors in reading, low inspection efficiency, and high skill requirements for operators. For scenarios involving specific dimensional ranges or batch inspections, a dedicated inspection tool is needed.

[0003] Currently, commonly used diameter measuring tools are generally caliper gauges or plug plates. Although fixed-specification caliper gauges or plug gauges are inexpensive, they can only inspect a single size, lack flexibility, and have a narrow range of applications. Therefore, there is an urgent need for a measuring tool that combines high precision, high efficiency, and a certain adjustable range, and can adapt to the inspection needs of different diameter sizes.

[0004] Therefore, it is necessary to provide an adjustable diameter gauge to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable diameter gauge, which solves the problem that commonly used diameter measuring tools are generally calipers or plugs, etc. Although fixed-specification calipers or plugs are inexpensive, they can only measure a single size, lack flexibility, and have a narrow range of applications.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable diameter gauge, comprising a base plate, a first positioning plate fixedly installed on the right side of the top of the base plate, a pressure plate provided on the outer side of the first positioning plate, a first positioning sleeve provided on the top of the base plate, a gauge clamp provided on the left side of the top of the base plate, a second positioning plate provided on the left side of the top of the base plate, a second positioning sleeve provided on the outer side of the second positioning plate, a slide provided on the top of the second positioning plate, an adjustable guide rail provided on the left side of the top of the base plate, a fixed guide rail provided on the right side of the second positioning plate, an outer sleeve provided on the left side of the top of the base plate, a compression spring provided inside the outer sleeve, and a screw plug provided on the left side of the outer sleeve.

[0007] Preferably, a connector is provided on the right side of the outer casing, a contact rod is provided on the right side of the outer casing, a reinforcing tube is provided on the top of the fixed guide rail, and a mechanical dial indicator is provided on the right side of the reinforcing tube.

[0008] The above technical solution, through the setting of a mechanical dial indicator, facilitates rapid workpiece inspection and achieves relatively high inspection efficiency.

[0009] Preferably, a first adjustment block is provided on the front side of the outer jacket, and a second adjustment block is provided on the right side of the first adjustment block.

[0010] The above technical solution, through the setting of the first adjustment block, facilitates stable adjustment.

[0011] Preferably, a protective cover is provided on the left side of the top of the base plate, a knurled high-head screw is provided on the right side of the protective cover, a B-type side head is provided on the top of the slide, and an adjustment handle is provided on the right side of the top of the base plate.

[0012] The above technical solution facilitates control and adjustment by adjusting the handle settings, saving time and effort.

[0013] Preferably, the number of adjustment handles is two, and the material of the adjustment handles is 45 steel.

[0014] By setting two adjustment handles made of 45# steel, on the one hand, the dual-handle design can achieve symmetrical adjustment on both sides, making it easier for users to operate with both hands, improving the balance and accuracy of the adjustment process, and avoiding uneven force caused by unilateral adjustment. On the other hand, 45# steel has high strength and wear resistance, which can effectively withstand torque and friction during long-term operation, reduce the risk of handle deformation or damage, extend the service life of the gauge, and ensure the stability and reliability of the adjustment function.

[0015] Preferably, the knurled high head screw is an M5 type, and the number of knurled high head screws is two.

[0016] The above technical solution uses two M5 knurled high-head screws. The M5 screw size is moderate, providing matching connection strength and tightening force, ensuring stable assembly between fixture components, and avoiding loosening or stripping due to improper thread specifications. The symmetrical distribution of the two screws can evenly distribute the fixing stress, enhance the overall stability of the connection structure, and prevent component displacement caused by single-point fixing. At the same time, the knurled surface treatment increases the friction for hand operation, making it easy for users to quickly tighten or loosen the screws manually without the need for tools, thus improving the efficiency of fixture disassembly, assembly, and adjustment.

[0017] Preferably, the number of watch clips is two, and the watch clips are made of 45# steel.

[0018] Through the above technical solution, by setting two gauge clamps made of 45# steel, the double gauge clamp structure can install measuring instruments separately, realizing simultaneous measurement of diameter on both sides or multi-point detection, effectively improving the accuracy and comprehensiveness of measurement data, avoiding the error of single-sided measurement. The 45# steel material has excellent rigidity and mechanical properties, which can provide stable support for measuring instruments, reduce measurement deviations caused by gauge clamp deformation, and enhance the impact resistance and durability of the gauge clamp, ensuring that the gauge maintains high-precision measurement performance during long-term use.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a B-type side head for measurement and observes the reading of a dial indicator. This reading is the deviation between the workpiece diameter and the standard gauge block size. Based on the tolerance requirements, it is possible to quickly determine whether the workpiece is qualified, which facilitates rapid measurement. Attached Figure Description

[0027] Furthermore, the setting of the first adjustment block 18 facilitates stable adjustments.

[0028] Please see Figure 1-2 A protective cover 20 is provided on the left side of the top of the base plate 1, and a knurled high-head screw 21 is provided on the right side of the protective cover 20. A B-type side head 22 is provided on the top of the slide plate 8, and an adjustment handle 23 is provided on the right side of the top of the base plate 1.

[0029] Furthermore, by adjusting the settings of the handle 23, it is easy to make control adjustments, saving time and effort.

[0030] Please see Figure 1-2 There are two adjustment handles 23, and the material of the adjustment handles 23 is 45 steel.

[0031] Furthermore, by setting two adjustment handles 23 and using 45# steel, on the one hand, the dual-handle design can achieve symmetrical adjustment on both sides, which is convenient for users to operate with both hands together, improves the balance and accuracy of the adjustment process, and avoids uneven force caused by unilateral adjustment. On the other hand, 45# steel has high strength and wear resistance, which can effectively withstand torque and friction during long-term operation, reduce the risk of handle deformation or damage, extend the service life of the gauge, and ensure the stability and reliability of the adjustment function.

[0032] Please see Figure 1-2 The knurled high head screw 21 is an M5 type, and there are two knurled high head screws 21.

[0033] Furthermore, the use of two M5 knurled head screws (21) ensures a stable assembly of fixture components, preventing loosening or stripping due to improper thread specifications. The symmetrical distribution of the two screws evenly distributes the fixing stress, enhancing the overall stability of the connection structure and preventing component displacement caused by single-point fixing. At the same time, the knurled surface treatment increases the friction for hand operation, making it easy for users to quickly tighten or loosen the screws manually without the need for tools, thus improving the efficiency of fixture assembly, disassembly, and adjustment.

[0035] Furthermore, by setting two gauge clamps 5 made of 45# steel, the double gauge clamp 5 structure allows for the separate installation of measuring instruments, enabling simultaneous measurement of diameter from both sides or multi-point detection. This effectively improves the accuracy and comprehensiveness of the measurement data, avoids errors from single-sided measurements, and the 45# steel material possesses excellent rigidity and mechanical properties, providing stable support for the measuring instruments and reducing measurement deviations caused by deformation of the gauge clamps 5. At the same time, it enhances the impact resistance and durability of the gauge clamps 5, ensuring that the gauge maintains high-precision measurement performance during long-term use.

[0036] The specific implementation process of this utility model is as follows: Although fixed-specification caliper gauges or plug gauges are inexpensive, they can only inspect a single size, lack flexibility, and have a narrow range of applications. Therefore, there is an urgent need for a gauge that combines high precision, high efficiency, and a certain adjustable range, and can adapt to the inspection needs of different diameter sizes. The workpiece to be measured is placed on the top of the base plate 1, and then measured with a dial indicator. The measurement is performed through the B-type side head 22, and the reading of the dial indicator is observed. This reading is the deviation between the workpiece diameter and the standard gauge block size. According to the tolerance requirements, it is possible to quickly determine whether the workpiece is qualified, which facilitates rapid measurement.

[0037] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
