Technical Field
[0001] This utility model relates to the field of depth measuring instrument technology, and in particular to a step hole depth measuring tool. Background Technology
[0002] For precision products, hole depth is an important dimension. The depth of the hole affects the product's assembly and, consequently, its subsequent function. Currently, depth measuring instruments are mainly used to measure and inspect the hole depth of products.
[0003] Currently, when measuring the depth of holes in products, the procedure involves manually holding the measuring instrument and inserting the measuring rod into the stepped hole for measurement. However, because the stepped surface of the hole is small, the measuring rod will tilt when manually holding the instrument, resulting in a large measurement error and low measurement efficiency.
[0004] Therefore, a step hole depth measuring instrument with good stability during the measurement process is needed to solve the current problems. Utility Model Content

Through multiple sets of clamping plates, the device can measure multiple workpieces, thus improving measurement efficiency.
[0006] The technical solution adopted to solve the above technical problems is: a stepped hole depth measuring instrument, including a depth measuring instrument body, a base, a positioning plate, multiple sliding parts and multiple sets of clamping plates. A support column is vertically connected to the upper side of the base. The positioning plate is rotatably connected to the upper end of the support column. The depth measuring instrument body is clamped on the positioning plate. Multiple sliding parts are evenly connected to the support column along the circumferential direction. The sliding parts slide along the axial direction of the support column. Multiple sets of clamping plates correspond one-to-one with the sliding parts. Each sliding part is slidably connected to a set of clamping plates.

The second lead screws are rotatably connected to the sliding member. The second lead screws are bidirectional lead screws. The ends of the second lead screws are connected to second knobs. Each second lead screw has a moving block threaded onto both ends. The moving blocks are slidably connected to the sliding member.
[0009] Furthermore, it also includes: each of the clamping plates is rotatably connected to the corresponding moving block, and a plurality of anti-slip textures are evenly provided on one side of the clamping plate, and a groove is provided on the other side of the clamping plate.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0017] like Figure 1-Figure 3 As shown, this embodiment provides a stepped hole depth measuring tool, including a depth measuring instrument body 1, a base 2, a positioning plate 4, multiple sliding parts 5, and multiple sets of clamping plates 6. A support column 3 is vertically connected to the upper side of the base 2, and the positioning plate 4 is rotatably connected to the upper end of the support column 3. The depth measuring instrument body 1 is clamped on the positioning plate 4. Multiple sliding parts 5 are evenly connected to the support column 3 along the circumferential direction. The sliding parts 5 slide along the axial direction of the support column 3. Multiple sets of clamping plates 6 correspond one-to-one with the sliding parts 5, and a set of clamping plates 6 is slidably connected to each sliding part 5.
[0018] This invention uses a positioning plate 4 to fix the depth measuring instrument body 1 to the upper end of the support column 3. The depth measuring instrument is stationary and has good stability. The workpiece to be measured is clamped on each set of clamping plates 6. By moving the sliding member 5 upward, the workpiece is moved upward, allowing the probe of the depth measuring instrument to be inserted into the step hole of the workpiece. With multiple sets of clamping plates 6, multiple workpieces can be measured, resulting in high-efficiency measurement. Through the above measurement method, the depth measuring instrument is kept in a stable vertical state during the measurement process, reducing errors caused by human shaking during the measurement process and improving its measurement accuracy. The multiple sets of clamping plates 6 enable the device to measure multiple workpieces, improving measurement efficiency.
[0019] Specifically, it also includes multiple first lead screws 7, multiple positioning blocks 9, and multiple sliding grooves 10. The multiple first lead screws 7 correspond one-to-one with the sliding parts 5. The first lead screws 7 pass through the sliding parts 5 and are movably connected to the sliding parts 5. The end of the first lead screw 7 is connected to a first knob 8. The multiple positioning blocks 9 correspond one-to-one with the first lead screws 7. The first lead screws 7 pass through the corresponding positioning blocks 9 and are threadedly engaged with the positioning blocks 9. The multiple sliding grooves 10 correspond one-to-one with the positioning blocks 9. The support column 3 is evenly provided with multiple sliding grooves 10 along the circumferential direction. The sliding grooves 10 are set vertically, and the positioning blocks 9 slide vertically in the sliding grooves 10.
[0020] In the above embodiments, the sliding member 5 is moved up and down by the positioning block 9 and the sliding groove 10. The positioning block 9 and the sliding member 5 are brought closer to each other by rotating the first lead screw 7, thereby fixing the height of the sliding member 5.
[0021] Specifically, it also includes multiple second lead screws 11 and multiple sets of moving blocks 13. The multiple second lead screws 11 correspond one-to-one with the sliding member 5. The second lead screw 11 is rotatably connected to the sliding member 5. The second lead screw 11 is a bidirectional lead screw. The end of the second lead screw 11 is connected to a second knob 12. Each second lead screw 11 has a moving block 13 threadedly sleeved at both ends. The moving block 13 is slidably connected to the sliding member 5. Each clamping plate 6 is rotatably connected to the corresponding moving block 13. Multiple anti-slip textures 14 are evenly provided on one side of the clamping plate 6, and a groove 15 is provided on the other side of the clamping plate 6.
[0022] In the above embodiments, the rotation of the second lead screw 11 drives the moving blocks 13 on both sides to move closer or further away from each other, thereby realizing the clamping operation of the clamping plates 6. The anti-slip texture 14 can clamp flat workpieces, and after rotation, the groove 15 clamps shaft workpieces.
[0023] Specifically, it also includes a connecting plate 16, multiple insert rods 17, multiple springs 18, and insertion holes 19. The connecting plate 16 is fixed to the upper end of the support column 3. Multiple insert rods 17 are evenly connected to the connecting plate 16 in the circumferential direction. The insert rods 17 are slidably connected to the connecting plate 16 in the vertical direction. The number of insert rods 17 is the same as the number of sliding parts 5. Multiple springs 18 correspond one-to-one with insert rods 17. Springs 18 are sleeved on insert rods 17. Insertion holes 19 are opened on the positioning plate 4. Insert rods 17 and insertion holes 19 are matched.
[0024] In the above embodiments, after the positioning plate 4 is rotated, the insertion rod 17 is inserted into the insertion hole 19 to realize the positioning operation of the positioning plate 4, thereby fixing the depth measuring instrument body 1 so that it can be aligned with the workpiece step hole for measurement, further improving its measurement accuracy.
[0025] The working principle of this utility model is as follows: It can perform measurement operations on multiple workpieces. Multiple workpieces are clamped between clamping plates 6. The clamping plates 6 are rotated according to the shape of the workpieces. For square shaft workpieces, the anti-slip texture 14 side is selected, and for round shaft workpieces, the groove 15 side is selected. Then, the second knob 12 is rotated to make the moving blocks 13 move closer to each other, thereby making the clamping plates 6 move closer to each other to clamp the workpieces. Then, the depth measuring instrument body 1 is used to measure the workpieces in sequence. The first knob 8 is rotated to make the first lead screw 7 rotate, and the positioning block 9 and the sliding member 5 move away from each other. The sliding member 5 can move up and down. The height of the sliding member 5 is adjusted so that the probe of the depth measuring instrument body 1 is inserted into the hole of the workpiece. After the height is adjusted, the first lead screw 7 is rotated to fix the position of the sliding member 5. The measurement data is obtained. The subsequent workpieces are measured in sequence. The insertion rod 17 is pulled, and the spring 18 is in a compressed state, so that the insertion rod 17 is separated from the insertion hole 19. The positioning plate 4 is rotated, thereby rotating the depth measuring instrument body 1, and the next insertion rod 17 is inserted into the insertion hole 19 and locked. The above operation is repeated to perform the measurement.
[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
