Description

Technical Field

[0001] This utility model relates to the field of thread gauge technology, and in particular to a thread gauge inspection tool with a chip removal groove. Background Technology

[0002] The machining of threaded holes is divided into two processes: drilling and tapping. The size of the bottom hole can be controlled during the drilling process. Therefore, the thread inspection only requires the use of a no-go gauge. After aligning the no-go gauge with the thread to be tested, rotate the thread gauge with your thumb and forefinger to allow it to rotate freely. Under normal circumstances, the length of the no-go gauge screwed into the thread is within two pitches, which is considered qualified. If it is forced through, it is judged as unqualified.

[0003] In the existing technology, when using a thread stop gauge, if the burrs and debris remaining from the machining inside the threaded hole enter the thread groove of the thread gauge, the thread gauge may damage the threads of the workpiece when it enters the threaded hole, affecting the overall pass rate of the workpiece. Furthermore, when carrying a thread stop gauge, the measuring thread head may be damaged due to misoperation or accidental contact. There is a lack of protective structure for the measuring thread head, making it inconvenient to use.

[0004] It should be noted that the information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model, and should not be regarded as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Therefore, the above content falls within the scope of the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0025] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] See Figures 1-3 A thread gauge inspection tool with a chip removal groove includes a protective tube 1, a thread gauge 2 slidably disposed inside the protective tube 1, a moving component 3 disposed inside the protective tube 1, the moving component 3 being used to drive the thread gauge 2 to extend and retract inside the protective tube 1, and a fixed rod 4 being fixedly connected to one end of the protective tube 1.

[0027] The protective tube 1 is supported and fixed by the fixing rod 4. The thread gauge 2 can be driven out of the protective tube 1 by the moving component 3 to inspect the threaded hole of the workpiece. After inspection, the thread gauge 2 is driven into the protective tube 1 by the moving component 3, thereby protecting the thread gauge 2 and preventing it from being bumped or damaged.

[0028] In the specific implementation process, such as Figure 2 As shown, the movable component 3 includes a connecting rod 31 fixedly installed at one end of the thread gauge 2. The top and bottom of the connecting rod 31 are fixedly connected to a movable block 32. A movable ring 33 is fixedly connected to the outside of the movable block 32. The top and bottom of the protective tube 1 are provided with movable grooves 34 that cooperate with the movable block 32.

[0029] The moving ring 33 drives the moving block 32 to move. The moving block 32 slides in the moving groove 34 and drives the connecting rod 31 to move, thereby causing the connecting rod 31 to drive the thread gauge 2 to move. This allows the thread gauge 2 to extend out of the protective tube 1 for inspection and retract into the protective tube 1, preventing the thread gauge 2 from being damaged by bumps.

[0030] The thread gauge 2 has a thread detection part 5 on its outer side and a tapered part 6 on one end.

[0031] Both the thread detection part 5 and the tapered part 6 are provided with multiple chip guide grooves 7, and the ends of the chip guide grooves 7 are connected to chip discharge grooves 8.

[0032] The thread gauge 2 enters the threaded hole through the thread inspection part 5 for inspection. The guide cone surface of the tapered part 6 first removes the burrs in the threaded hole. These burrs first enter the guide cone surface and the chip guide groove 7 of the thread inspection part 5. Some of the burrs that enter the tooth groove of the thread inspection part 5 will also quickly enter the chip guide groove 7. The chip guide groove 7 guides the burrs and waste to the chip removal groove 8. The chip removal groove 8 removes the burrs and waste, thereby reducing the resistance of the thread gauge 2 entering the threaded hole and avoiding damage to the workpiece thread.

[0033] Both sides of the movable ring 33 are fixedly connected to a fixing block 9, and a positioning block 10 is fixedly connected to one side of the fixing block 9.

[0034] A positioning bolt 11 is screwed onto the inner wall of the positioning block 10, and one end of the positioning bolt 11 abuts against the outer side of the protective tube 1.

[0035] When the moving ring 33 moves, it drives the fixed block 9 and the positioning block 10 to move synchronously. After the moving ring 33 has moved, the positioning bolt 11 is tightened to position the moving ring 33, thereby fixing the position of the thread gauge 2 and making it convenient to use the thread gauge 2.

[0036] In use, the moving ring 33 drives the moving block 32 to move. The moving block 32 slides in the moving groove 34 and drives the connecting rod 31 to move, thereby causing the connecting rod 31 to drive the thread gauge 2 to move. This allows the thread gauge 2 to extend out of the protective tube 1 for inspection and retract into the protective tube 1, preventing the thread gauge 2 from being damaged by impact. It enters the thread hole through the thread detection part 5 for inspection. The guide cone surface of the tapered part 6 first removes burrs in the thread hole. These burrs first enter the guide cone surface and the chip guide groove 7 of the thread detection part 5. Some of the burrs that enter the tooth groove of the thread detection part 5 will also quickly enter the chip guide groove 7. The chip guide groove 7 guides the burrs and waste to the chip removal groove 8, and the chip removal groove 8 discharges the burrs and waste, thereby reducing the resistance of the thread gauge 2 entering the thread hole and avoiding damage to the workpiece thread.
