[0022] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0023] Reference Figure 1-6 As shown, a chamfer angle detection tool includes a measuring component 1; The measuring component 1 includes a bracket 11, a scale 12 mounted on the bracket 11, and a pointer 13 that cooperates with the scale 12; The shape of the contact portion between pointer 13 and the part under test 2 is adapted; The test piece 2 corresponds to the position of the pointer 13. By pushing and rotating the pointer 13, one end of the pointer 13 extends into the interior of the test piece 2 and fits against the inner chamfer of the test piece 2, while the other end points to the corresponding scale of the scale 12.

[0024] like Figure 1 As shown, during use, the test piece 2 is installed at the position corresponding to the pointer 13, and the bracket 11 can be moved or installed on the worktable by means of a sliding connection or support structure. For example, an installation connection structure can be set on the operating platform to connect with the bracket 11 for temporary or permanent fixation of the bracket 11. A sliding structure can also be set to move the bracket 11 to the position corresponding to the test piece 2. Alternatively, the bracket 11 can be fixed and the test piece 2 can be placed in the slot for operation. like Figure 1 As shown, pointer 13 is rotatably mounted on moving block 5 (or on bracket 11). After bracket 11 is aligned with the position of the workpiece 2 to be tested, pointer 13 is rotated so that one end (tip or detection end) of pointer 13 extends into the interior of workpiece 2 to be tested and fits against the inner arc surface of the inner chamfer of workpiece 2 to be tested. Its other end (i.e., the indicator end) will rotate synchronously and point to the corresponding mark on scale 12; The scale 12 is pre-calibrated with angle values. By reading the scale indicated by the pointer 13, the angle value of the chamfered part of the workpiece 2 to be tested can be obtained directly. Compared with the existing technology, this solution, after installing the part to be tested 2, rotates the pointer 13 so that one end is in contact with the part to be tested, and the other end naturally points to the angle value on the scale 12, converting the geometric angle of the chamfer to be tested into a visible reading on the scale 12, thereby realizing the rapid and direct detection of the chamfer angle of the part to be tested 2, and thus accurately screening out qualified parts to be tested 2 that meet the requirements. Meanwhile, the tool is relatively lightweight, allowing for testing on the production line at any time, saving inspection time and improving production inspection efficiency.

[0025] Preferably, it includes a base 3 and sliding grooves 31 disposed on both sides of the base 3; The bracket 11 is equipped with a slider 111; The slider 111 is installed in the slide groove 31 and connected to the bracket 11; The bracket 11 moves along the fixed trajectory of the slide groove 31 via the slider 111.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the bracket 11 is slidably connected to the groove 31 on the base 3 via the slider 111 thereon; The slide 31 provides a stable movement trajectory for the slider 111, ensuring that the bracket 11 and the measuring component 1 mounted thereon can move along the predetermined trajectory; The connection between the slider 111 and the bracket 11 can be a fixed connection (e.g., welding, screw connection) or an integral molding, thereby ensuring that the movement of the slider 111 can be accurately transmitted to the bracket 11; The measurement operation process can be optimized as follows: the test piece 2 is installed in a fixed position, the operator pushes the bracket 11 through the slider 111 to make it slide along the specified trajectory of the slide groove 31, thereby driving the entire measurement assembly 1 to move closer to the test piece 2 along the fixed trajectory of the slide groove 31 to find the best measurement position. After the measurement is completed, the bracket 11 is moved to reset it and the test piece 2 is taken out. The groove 31 and the slider 111 work together to avoid the shaking or positional deviation that may occur when the handheld support 11 is used for measurement, thereby improving the repeatability and accuracy of the test.

[0027] Preferably, a first spring 32 is provided inside the slide groove 31; The first spring 32 connects the slide groove 31 and the slider 111, and is used to drive the slider 111 to move to the initial position within the slide groove 31.

[0028] like Figure 3 As shown, the two ends of the first spring 32 can be directly hooked, snapped, welded, or fixedly connected to the inner wall of the end of the slide groove 31 and the slider 111 respectively through spring seats; When the operator pushes the bracket 11 and slider 111 to move in one direction (closer to the test piece 2) along the slide groove 31 against the elastic force of the first spring 32, once the pushing force is released, the slider 111 will be automatically pulled back to the initial position under the restoring force of the first spring 32. This reset function allows the measuring tool to automatically return to the ready state after completing a measurement, facilitating the next measurement and improving operational efficiency.

[0029] Preferably, a damper 33 is also provided inside the slide groove 31; The damper 33 is connected to the slider 111 and is used to slow down the reset speed of the slider 111.

[0030] The damper 33 can be a hydraulic damper 33, an air damper 33, or a friction damper 33, etc. Its fixed end is connected to the slide groove 31 by means of screws, clips or welding, and its movable end is connected to the slider 111 in a similar way. When the slider 111 is reset under the action of the first spring 32, it will drive the moving end of the damper 33 to move. The throttling of the medium (such as oil or gas) inside the damper 33 or the resistance generated by the friction components will act on the slider 111, thereby slowing down its reset speed. Meanwhile, the damper 33 can also be an elastic element made of elastic material, which is set on the side of the slider 111 to fill the gap between the slider 111 and the groove 31, thereby increasing the friction to slow down the speed during reset. To prevent the slider 111 from rapidly and violently impacting the end of the slide groove 31 under the action of the first spring 32, the slide groove 31, slider 111 and related connecting structures are protected, reducing wear and noise while extending their service life. At the same time, the smooth reset process also makes the tool easier to operate.

[0031] Preferably, it includes a mounting base 4 connected to the base 3; The mounting base 4 is provided with a mounting groove 41 for mounting the test piece 2, and the shape of the mounting groove 41 is adapted to the shape of the test piece 2. The mounting base 4 is provided with a pin 42; The base 3 is provided with a fixing groove 34 that mates with the keyway of the pin 42; Mounting bracket 4 is inserted into base 3.

[0032] In actual operation, the equipment usually has several test pieces 2 that need to be chamfered. At this time, the fixed slot may not be suitable for all test pieces 2. Therefore, a mounting bracket 4 was added for mounting the component under test 2; like Figure 4 As shown, the test piece 2 can be placed or snapped into the mounting slot 41; The mounting base 4 and the base 3 are connected by a plug-in connection. like Figure 4 The mounting base 4 has a pin 42 extending from its side, while the base 3 has a fixing groove 34 that matches its shape and position. By aligning the pin 42 and inserting it into the fixing groove 34, the mounting base 4 and the base 3 can be quickly aligned and fixed. This plug-in connection method facilitates the removal and replacement of mounting base 4; This allows the testing tool to be adapted to test pieces 2 of different sizes or types by replacing the mounting base 4 with mounting slots 41 of different specifications, thus expanding the tool's versatility.

[0033] Preferably, the bracket 11 is provided with a locking element 112; The mounting base 4 is provided with a through hole 43; The locking element 112 engages with the through hole 43 to lock or unlock the bracket 11.

[0034] When the movable bracket 11 moves to the position corresponding to the test piece 2, it pushes the locking piece 112 so that it is inserted into the through hole 43, thereby restricting the reset of the bracket 11. By fixing the position of the bracket 11, when measuring the same batch of test pieces 2, the pointer 13 is rotated to fix the rotation degree of the pointer 13 that controls the chamfer angle of the test piece 2. Then, the test piece 2 to be tested is placed in. When the test piece 2 meets the standard, the pointer 13 is in close contact with the chamfer part of the test piece 2. When a non-compliant test piece 2 is placed in the mounting slot 41, the pointer 13 will have a gap with the chamfer part of the test piece 2, or the test piece 2 will abut against the pointer 13, thereby pushing the pointer 13 to rotate. This method can quickly test the same batch of test pieces 2, increasing work efficiency.

[0035] Preferably, a mating part 44 is provided in the mounting base 4 at the position corresponding to the through hole 43; Move the bracket 11 so that the position of the locking member 112 corresponds to the through hole 43. The locking member 112 passes through the through hole 43 and engages with the mating member 44 to lock the bracket 11. The mating part 44 is connected to the pushing part 45; The pusher 45 pushes the mating part 44 to move, thereby releasing the locking state of the mating part 44 and the locking part 112.

[0036] like Figure 4 and Figure 5 As shown, the bracket 11 is provided with a hole for the locking member 112 to pass through, and by adding a spring, it can automatically reset after pressing the locking member 112; The mating part 44 is disposed inside the mounting base 4, and its position corresponds to the through hole 43; When performing the locking operation, move the bracket 11 along the slide 31 until the locking piece 112 on the bracket 11 is aligned with the through hole 43 on the mounting base 4; Then, press the locking member 112 so that it passes through the through hole 43 and forms a locking engagement with the mating member 44 inside the mounting base 4; When unlocking is required, push the exposed pusher 45 to move the mating part 44, thereby releasing the locking engagement between the locking part 112 and the mating part 44. The locking part 112 returns to its original position under the action of the spring, and the pusher 45 also returns to its original position under the action of the spring. One locking and unlocking method involves setting magnets that attract each other on the locking member 112 and the mating member 44. When the locking member 112 passes through the through hole 43 and contacts the mating member 44, the locking member 112 and the mating member 44 are locked by magnetic attraction. When unlocking, push the pusher 45 to cause the mating member 44 to separate from the locking member 112. The locking member 112 loses the magnetic attraction and resets under the action of the spring. After the pusher 45 is released, the pusher 45 also causes the mating member 44 to reset under the action of the spring, thus realizing the two states of locking and unlocking. The pusher 45 is located on the outside of the mounting base 4 in a position that is easy to operate, and is connected to the mating part 44 inside the mounting base 4 by means of a connecting rod, cam or direct connection, so that the action of the pusher 45 will be transmitted to the mating part 44 inside, driving the mating part 44 to move.

[0037] Preferably, the locking member 112 is provided with a locking groove 1121; The mating part 44 is provided with mating holes 441, and some of the mating holes 441 are outside the moving path of the locking part 112; A guide surface 442 is provided on the edge of the port of the mating hole 441 near the locking member 112; A second spring is provided between the locking member 112 and the bracket 11, and the second spring is used to drive the locking member 112 to reset. A third spring is provided between the pusher 45 and the mounting base 4, which is used to drive the pusher 45 to reset. Move the locking member 112 so that it abuts against the guide surface 442, thereby driving the mating member 44 to move, so that the locking member 112 drives the locking groove 1121 to smoothly insert into the mating hole 441, and under the action of the third spring, the pushing member 45 drives the mating member 44 to reset, and the locking groove 1121 and the mating hole 441 form a keyway fit, locking the locking member 112 and the mating member 44; The pusher 45 is moved to separate the mating hole 441 from the locking groove 1121. Under the action of the second spring, the locking member 112 drives the locking groove 1121 to reset, releasing the locking member 112 and the mating member 44 from their locked state.

[0038] like Figure 5 As shown, the mating hole 441 on the mating part 44 is misaligned with the through hole 43 (the through hole 43 is not shown to visually show the internal connection structure), and the port edge of the mating hole 441 is provided with a guide surface 442. Pushing the locking part 112 allows it to pass through the through hole 43 and then squeeze the mating part 44, causing the mating part 44 to move. This allows the locking part 112 to smoothly enter the mating hole 441 of the mating part 44. Under the action of the third spring, the mating part 44 is reset, so that the mating hole 441 and the locking groove 1121 form a keyway fit, thereby locking the locking part 112 and preventing the bracket 11 from resetting. At this time, the second spring is in a compressed state, and the third spring is in a free state. Meanwhile, as long as the mating part 44 can be reset so that the locking groove 1121 and the mating hole 441 can form a keyway fit, it can be used as an implementation of this solution. For example, adding elastic elements, magnets, etc., so that the mating part 44 can move in the opposite direction of the moving after being moved by the abutment, thereby locking the locking groove 1121. When released, push the pusher 45 to compress the third spring, causing the mating hole 441 of the mating part 44 to separate from the locking groove 1121. At this time, the second spring drives the locking part 112 to return to its initial position, thereby completely separating the mating hole 441 and the locking groove 1121. After the force applied to the pusher 45 is released, the third spring drives the pusher 45 to reset. At this time, both the second spring and the third spring are in their natural state. This design allows for a direct visual indication of whether the locking element 112 and the mating element 44 are in a locked state by checking whether the second spring is in a compressed state. Pressing the locking element 112 locks the device, while pushing the pusher element 45 unlocks it. This simple action allows for both locked and unlocked states, simplifying the measurement process.

[0039] Preferably, it includes moving block 5; Both the scale 12 and the pointer 13 are mounted on the moving block 5; The movable block 5 is slidably connected to the bracket 11, thereby driving the scale 12 and pointer 13 to move.

[0040] When it is necessary to measure the test piece 2 of different specifications, the height can be adjusted so that the pointer 13 reaches the optimal height, thereby increasing the accuracy of the measurement; Compared to a fixed scale 12 and pointer 13, when dealing with test pieces 2 of different specifications, it may be that pointer 13 is too short to contact test piece 2 or too long to fit closely to the chamfer of test piece 2. A higher scale 12 and a longer pointer 13 can also be used to measure different sizes of test pieces 2. However, such a setting may cause the pointer 13 to break when the pointer 13 is too long, during the moving bracket 11 and the measurement process. At the same time, the pointer 13 may not be able to be inserted into the test piece 2. Therefore, when the pointer 13 cannot be inserted into the part to be measured 2, the pointer 13 can be moved upward by the moving block 5. After adjusting the rotation angle of the pointer 13, the pointer 13 can be moved downward by the moving block 5 so that it can smoothly enter the interior of the part to be measured 2 and measure its inner chamfer. Therefore, a sliding block 5 is used to slide and connect with the support 11. The scale 12 and pointer 13 are moved and adjusted by the sliding block 5 to adapt to the measurement of test pieces 2 of different specifications.

[0041] Preferably, the movable block 5 includes a first flange 52, a second flange 53, and a web 54; The web 54 is connected to the first flange 52 and the second flange 53 at both ends, respectively. The bracket 11 is provided with a movable groove that is compatible with the first flange 52, so that the first flange 52 can move along the fixed trajectory of the movable groove; The scale 12 and pointer 13 are both mounted on the second flange 53; A threaded hole is provided on the first flange 52; The end of bolt 51 passes through the threaded hole and abuts against the bottom surface of the moving groove, restricting the movement of moving block 5.

[0042] The installation method of scale 12 can be as follows Figure 3 As shown, a scale 12 is installed between the two moving blocks 5, and the two moving blocks 5 are connected by bolts 51; When the height needs to be adjusted, the first flange 52 and the second flange 53 are moved by holding the web plate 54, thereby moving the scale 12 and the pointer 13. When it is necessary to fix the movable block 5, rotate the bolt 51 so that its end abuts against the bottom of the movable groove, restricting the movement of the movable block 5, thereby fixing the height of the scale 12 and the pointer 13; At the same time, the force exerted by the bolt 51 on the moving groove can be adjusted, so that the moving block 5 can be moved but will not fall off due to gravity, simplifying the operation steps during measurement; Meanwhile, this locking method has a simple structure, low cost, and intuitive operation. Loosening the bolt 51 will release the lock and facilitate position adjustment.

[0043] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
