Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a precision deep hole eccentric gauge. Background Technology

[0002] In industrial production, conduits are common components, and many conduits have precision deep holes inside. The eccentricity of these precision deep holes directly affects the performance and quality of the conduits. For example, in the aerospace field, if the deep holes in the conduits of an engine are too eccentric, it may lead to uneven flow of fuel or coolant, affecting the engine's efficiency and stability. In automobile manufacturing, eccentricity of the deep holes in conduits such as fuel lines or hydraulic lines may cause fuel leaks or hydraulic system malfunctions, posing safety hazards.

[0003] Currently, traditional methods for detecting eccentricity in precision deep holes within catheters have many shortcomings. Some detection methods are complex to operate, requiring specialized technicians, and are inefficient, making them unsuitable for large-scale production. Furthermore, some detection equipment is inconvenient to install, further contributing to low efficiency. Therefore, developing a precision deep hole eccentricity gauge that is easy to operate, accurately positioned, and highly efficient is of significant practical importance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing testing equipment, such as inconvenient installation leading to low testing efficiency, by proposing a precision deep-hole eccentric gauge.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precision deep hole eccentric inspection tool includes a base, a slide rail fixed to the top of the base, two self-locking sliders sliding on the surface of the slide rail, a mounting seat 1 fixed to the top of each of the two self-locking sliders, and a positioning cone rotating at the close ends of the two mounting seats 2. The two positioning cones are used to insert into the deep hole to position the guide tube to be inspected.

[0007] To facilitate catheter positioning, two sets of placement components are provided on the slide rail for convenient catheter placement;

[0008] And a compression assembly used in conjunction with the two sets of placement components, the compression assembly being used to lift the two sets of placement components to facilitate placement of the conduit;

[0009] The top of the base is equipped with a detection component for detecting eccentricity.

[0010] In one possible design, one of the mounting bases has a rotating shaft, one of the positioning cones is fixed to the side end of the rotating shaft, and a first handle is fixed to the side end of the rotating shaft. The first handle is used to drive the positioning cone and the guide tube held by the positioning cone to rotate for measurement.

[0011] In one possible design, each set of placement components includes a second slider that slides on the surface of a slide rail. The top of the second slider is fixed with a second mounting base. The second mounting base has a fourth groove. A V-shaped placement block slides in the fourth groove. A fifth groove is formed in the V-shaped placement block. The second mounting base has a second groove that communicates with the fourth groove. A pressing block slides in the second groove. A movable block is fixed at the top of the pressing block. The movable block is located in the fifth groove. A sliding rod is fixed in the movable block. Two sliding grooves are formed in the fifth groove. The sliding rod slides in the two sliding grooves.

[0012] The V-shaped placement block is adjusted by sliding the slider left and right in the groove, thereby driving the V-shaped placement block to move up and down relative to each other and adjusting the height of the V-shaped placement block.

[0013] In one possible design, each set of placement components further includes a third groove formed within the extrusion block, wherein a spring is provided in the third groove, and the two ends of the spring abut against the inner walls of the second groove and the third groove respectively via spring seats.

[0014] The spring's elasticity can push the squeezing block and the movable block to the far right, so that the slide rod is at the highest point of the slide groove, and the V-shaped placement block is positioned in the fourth groove.

[0015] In one possible design, the extrusion assembly includes a first groove formed in the base, two limiting rods fixed in the first groove, the surfaces of the two limiting rods slidingly with the same threaded plate, a lead screw rotating in the first groove, a slider fitted on the outer wall of the lead screw for use with the spiral groove of the lead screw, the slider being fixed in the threaded plate, an extrusion plate fixed at the top of the lead screw, the extrusion plate and two extrusion blocks making extrusion contact, and a second handle fixed at the side end of the lead screw moving outward through the base;

[0016] The second throttle is turned to drive the lead screw to rotate, which can drive the two extrusion blocks to move the movable block and the movable block to move. The position of the V-shaped placement block is adjusted upward to facilitate the placement of the tube to be inspected. After placement, the self-locking slider can be moved to drive the mounting seat on one side to clamp the tube to be inspected. Then the lead screw is flipped to release the support.

[0017] In one possible design, the detection assembly includes a universal arm fixed to the top of the base, with a dial indicator for detecting eccentricity fixed inside the universal arm, the dial indicator being in contact with the surface of the conduit to be tested.

[0018] In this application, the screw is rotated by turning the second throttle, which in turn drives the threaded plate and the extrusion plate to move. The extrusion plate moves and extrudes two extrusion blocks, which in turn drive the movable block and the movable block to move. The position of the V-shaped placement block is adjusted upward to facilitate the placement of the tube to be inspected. After placement, the self-locking slider can be moved to clamp the mounting seat on one side of the tube to be inspected. Then the screw is flipped to release the support.

[0019] The V-shaped placement block is moved up and down relative to the slide by adjusting the left and right sliding rod in the slide groove, thereby adjusting the height of the V-shaped placement block;

[0020] The elasticity of the spring can push the squeezing block and the movable block to the far right, so that the slide bar is located at the highest point of the slide groove, and the V-shaped placement block is positioned in the fourth groove.

[0021] Beneficial Effects: This utility model discloses a precision deep-hole eccentric gauge that, through the arrangement of two sets of placement components and a compression component, achieves flexible adjustment of the guide tube placement height. When placing the guide tube, rotating the second throttle rotates the lead screw, causing the compression plate to compress the compression block, thereby adjusting the height of the V-shaped placement block 20, facilitating accurate placement of the guide tube in the appropriate position. After the guide tube is placed, moving the self-locking slider drives the mounting base and positioning cone to clamp and position the guide tube. The operation is simple and convenient, greatly improving the preparation efficiency for inspection.

[0022] In this invention, a precision deep-hole eccentricity gauge is described, in which the positioning cone is designed to accurately insert into the precision deep hole of a guide tube, achieving precise positioning of the guide tube. One of the positioning cones is connected to a first rotating handle via a rotating shaft. Rotating the first rotating handle causes the positioning cone and the clamped guide tube to rotate. Combined with a dial indicator for multi-angle measurement, this allows for a more comprehensive and accurate detection of the eccentricity of the deep hole, improving the reliability of the detection results.

[0023] In this invention, the overall structure is compact and reasonable, and the components work together. The positioning and eccentricity detection of the conduit can be completed through simple mechanical operation. No complex electronic control system or professional skills are required, which reduces equipment cost and ease of use, making it suitable for wide application in various production environments.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] In one embodiment: Refer to Figures 1-5 A precision deep-hole eccentric gauge, applied in the field of testing equipment technology, includes a base 1, which serves as the supporting foundation for the entire gauge. A slide rail 2 is fixedly installed at the top of the base 1. Two self-locking sliders 3 are slidably disposed on the surface of the slide rail 2, and each of the two self-locking sliders 3 has a mounting seat 5 fixed at its top. Positioning cones 6 are rotatably installed at the adjacent ends of the two mounting seats 5. These two positioning cones 6 are used to insert into the deep hole to achieve positioning of the guide tube to be inspected.

[0032] To facilitate the positioning of the conduit, two sets of placement components are provided on the slide rail 2. Each set of placement components includes a second slider 4 that slides on the surface of the slide rail 2, and a mounting base 13 is fixed to the top of the second slider 4. A fourth groove 28 is formed in the mounting base 13, and a V-shaped placement block 20 is slidably installed in the fourth groove 28. A fifth groove 21 is formed in the V-shaped placement block 20. A second groove 25 is formed in the mounting base 13 that communicates with the fourth groove 28. A pressing block 14 is also slidably installed in the second groove 25. A movable block 22 is fixed to the top of the pressing block 14 and is located in the fifth groove 21. A sliding rod 23 is fixed in the movable block 22. Two sliding grooves 24 are formed in the fifth groove 21, and the sliding rod 23 slides in the two sliding grooves 24. By adjusting the sliding of the sliding rod 23 in the sliding grooves 24, the V-shaped placement block 20 can be driven to move up and down relative to the sliding rod 24, thereby adjusting the height of the V-shaped placement block 20.

[0033] Each placement assembly also includes a third groove 27 formed within the extrusion block 14. A spring 26 is disposed within the third groove 27, and the two ends of the spring 26 abut against the inner walls of the second groove 25 and the third groove 27 respectively via spring seats. Under the elastic action of the spring 26, the extrusion block 14 and the movable block 22 can be pushed to the rightmost position, so that the slide rod 23 is located at the highest point of the slide groove 24, thereby positioning the V-shaped placement block 20 within the fourth groove 28;

[0034] The compression assembly works in conjunction with the two placement components. The compression assembly includes a first groove 16 formed within the base 1, with two limiting rods 17 fixed within the first groove 16. A threaded plate 18 is slidably mounted on the surface of the two limiting rods 17. A lead screw 19 is rotatably mounted within the first groove 16, and a slider that engages with the spiral groove of the lead screw 19 is fitted onto its outer wall.

The side end of the lead screw 19 extends outward through the base 1 and is fixed with a second handle 11. Rotating the second handle 11 causes the lead screw 19 to rotate, which in turn moves the threaded plate 18 and the compression plate 12. The compression plate 12 moves and compresses the two compression blocks 14, which in turn move the movable block 22 and the sliding rod 23, thereby adjusting the position of the V-shaped placement block 20 upwards for easier placement of the guide tube to be inspected. After the conduit is placed, the self-locking slider 3 can be moved to clamp the mounting seat 5 on one side of the conduit to be inspected, and then the screw rod 19 can be flipped to release the support.

The detection component includes a universal arm 9 fixed to the top of the base 1, and a dial indicator 10 for detecting eccentricity is fixed inside the universal arm 9. The dial indicator 10 is in contact with the surface of the conduit to be tested, and the eccentricity of the conduit is detected by the change in the reading of the dial indicator 10.

[0036] A rotating shaft 8 is rotatably mounted in one of the mounting bases 5, and a positioning cone 6 is fixed to the side end of the rotating shaft 8. A first handle 7 is fixed to the side end of the rotating shaft 8. By rotating the first handle 7, the positioning cone 6 and the catheter held by the positioning cone 6 can be rotated for measurement, thereby more comprehensively detecting the eccentricity of the catheter.
