Description

Technical Field

[0001] This utility model belongs to the field of automotive repair gauge technology, and more specifically, it relates to a quick zeroing auxiliary device for a gauge. Background Technology

[0002] A cylinder gauge, also known as an inside micrometer, is a comparative measuring tool used to measure bore diameter. In automotive repair, it is mainly used to measure the roundness and cylindricity errors of engine cylinders and bearing housing bores, as well as cylinder wear. When using a cylinder gauge to measure the internal dimensions of cylinders and bores, zeroing with a dial indicator is a crucial step to ensure measurement accuracy. Essentially, this "datum calibration" eliminates measurement system errors, standardizes the measurement benchmark, and ultimately achieves precise measurement of "dimensional deviations."

[0003] Currently, in the cylinder diameter measurement training, students are not proficient in the operation. When using a micrometer for secondary zeroing, the measuring rod of the cylinder gauge cannot be correctly inserted into the micrometer or easily slips out of the micrometer, resulting in inaccurate zeroing and excessively long zeroing time, leading to low efficiency in the training operation.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a quick zeroing auxiliary device for the gauge cylinder, in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a quick zeroing auxiliary device for a caliper gauge, which is achieved by the following specific technical means: A quick zeroing auxiliary device for a measuring cylinder gauge includes a measuring cylinder gauge and a micrometer. The measuring cylinder gauge includes a measuring rod, a dial indicator, and a measuring head. The dial indicator and the measuring head are respectively installed at the upper and lower ends of the measuring rod. The micrometer includes a frame, a measuring anvil, and a micrometer screw. An auxiliary fixing mechanism is installed on one side of the frame. The auxiliary fixing mechanism includes a mounting base one and a mounting base two. The mounting base one and the mounting base two are symmetrically installed on one side of the frame. The mounting base one has a mounting groove on the side near the mounting base two. Both sides of the mounting groove have sliding grooves. The mounting groove is slidably connected to a movable seat through the sliding grooves. A clamping plate one is fixedly connected to the movable seat on the side near the opening of the mounting groove. A clamping plate two is fixedly connected to the side of the mounting base two near the mounting base one. The clamping plates one and two are respectively located on both sides of the measuring rod.

[0006] Furthermore, both clamp plate one and clamp plate two are arc-shaped and adapted to the measuring rod, and both clamp plate one and clamp plate two have anti-slip texture on the side near the measuring rod.

[0007] Furthermore, both sides of the movable seat are provided with sliders, which are slidably connected to the slide groove, and the movable seat is fixedly connected to a handle at one end near the outer side of the mounting groove.

[0008] Furthermore, a compression spring is fixedly connected to one side of the mounting groove, and one end of the compression spring is fixedly connected to the movable seat.

[0009] Furthermore, a pair of threaded holes are symmetrically provided on one side of the ruler frame, and mounting screws are provided on one side of both mounting base one and mounting base two, and the mounting screws engage with the threaded holes.

[0010] Furthermore, the anvil and the micrometer screw are respectively installed on both sides of the bottom end of the ruler frame, and the probe is installed between the anvil and the micrometer screw.

[0011] Furthermore, the top of the measuring rod is provided with a clamp, and the measuring rod is fixedly installed to the dial indicator by the clamp.

[0012] Furthermore, the ruler frame is equipped with a stop knob on one side of the micrometer screw, the micrometer screw is equipped with a differential cylinder at the end away from the ruler frame, and a fine-tuning knob is installed at one end of the differential cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This utility model discloses a quick zeroing auxiliary device for a micrometer gauge. Through the cooperation of a mounting base, mounting groove, movable base, and clamping plate, the measuring rod of the micrometer gauge is aligned and pressed between clamping plate one and clamping plate two. The force of the compression spring in the mounting groove causes clamping plate one to move and cooperate with clamping plate two to clamp and fix the measuring rod. This effectively maintains the relative position of the micrometer gauge and the micrometer, and solves the problem of the micrometer gauge slipping out of the micrometer. It is of great help to those who are not familiar with the operation or are first-time users. Attached Figure Description

[0021] As attached Figure 1 Appendix Figure 2 and attached Figure 3 As shown: This utility model provides a quick zeroing auxiliary device for a measuring cylinder gauge, including a measuring cylinder gauge and a micrometer. The measuring cylinder gauge includes a measuring rod 1, a dial indicator 102, and a measuring head 103. The dial indicator 102 and the measuring head 103 are respectively installed at the upper and lower ends of the measuring rod 1. The micrometer includes a frame 2, a measuring anvil 201, and a micrometer screw 202. An auxiliary fixing mechanism is installed on one side of the frame 2. The auxiliary fixing mechanism includes a mounting base 3 and a mounting base 4, which are symmetrically installed on the frame 2. On one side, the mounting base 3 is provided with a mounting groove 301 on the side near the mounting base 4. Both sides of the mounting groove 301 are provided with sliding grooves 306. The mounting groove 301 is slidably connected to the movable base 302 through the sliding grooves 306. The movable base 302 is fixedly connected to the clamping plate 303 on the side near the opening of the mounting groove 301. The mounting base 4 is fixedly connected to the clamping plate 401 on the side near the mounting base 3. The clamping plate 303 and the clamping plate 401 are located on both sides of the measuring rod 1.

[0022] Among them, clamp 1 303 and clamp 2 401 are both arc-shaped and adapted to the measuring rod 1, and clamp 1 303 and clamp 2 401 are provided with anti-slip texture 402 on the side near the measuring rod 1.

[0023] The movable seat 302 is provided with sliders 307 on both sides. The sliders 307 are slidably connected to the slide groove 306. The sliders 307 facilitate the movement of the movable seat 302 inside the mounting groove 301. A handle 304 is fixedly connected to one end of the movable seat 302 near the outside of the mounting groove 301. The handle 304 facilitates the movement of the movable seat 302 inside the mounting groove 301.

[0024] A compression spring 305 is fixedly connected to one side inside the mounting groove 301, and one end of the compression spring 305 is fixedly connected to the movable seat 302. The force of the compression spring 305 is used to realize the self-rebound of the movable seat 302 in the mounting groove 301, so that the clamping plate 303 clamps and fixes the measuring rod 1.

[0025] The ruler frame 2 has a pair of threaded holes 206 symmetrically opened on one side. Mounting seat 3 and mounting seat 4 are each provided with mounting screws 308 on one side. The mounting screws 308 and the threaded holes 206 are engaged with each other. Through the setting of the threaded holes 206 and the mounting screws 308, mounting seat 3 and mounting seat 4 can be fixedly installed on the ruler frame 2.

[0026] The anvil 201 and the micrometer screw 202 are respectively installed on both sides of the bottom end of the ruler frame 2, and the measuring head 103 is installed between the anvil 201 and the micrometer screw 202.

[0027] The measuring rod 1 has a clamp 101 at its top end, and the measuring rod 1 is fixedly installed to the dial indicator 102 through the clamp 101. The clamp 101 facilitates the installation of the measuring rod 1 and the dial indicator 102.

[0028] The ruler frame 2 has a stop knob 203 installed on one side of the micrometer screw 202. The micrometer screw 202 has a micrometer cylinder 204 installed at the end away from the ruler frame 2, and a fine adjustment knob 205 is installed at one end of the micrometer cylinder 204. The stop knob 203 facilitates the fixation of the micrometer screw 202.

[0029] The working principle of this embodiment is as follows: First, mounting base 3 and mounting base 4 are symmetrically installed on one side of the ruler frame 2 using mounting screws 308. During use, the measuring rod 1 of the gauge cylinder is first pressed between clamping plates 303 and 401. Under pressure, clamping plate 303 drives the movable seat 302 to move inwards into the mounting groove 301 using slider 307 and slide groove 306. Once the measuring rod 1 enters the inner side of clamping plates 303 and 401, the compression spring 305 within the mounting groove 301 causes the movable seat 302 to reset clamping plate 303, and in conjunction with... Clamping plate 2 401 clamps and fixes measuring rod 1, which can effectively maintain the relative position of the measuring cylinder gauge and the micrometer, and solve the problem of the measuring cylinder gauge slipping out of the micrometer. This is of great help to inexperienced operators and first-time users. Finally, when it is necessary to remove measuring rod 1, simply pull the handle 304 on one side of the movable seat 302, and use the sliding groove 306 and the slider 307 to retract the movable seat 302 in the mounting groove 301. This increases the distance between clamping plate 1 303 and clamping plate 2 401, causing clamping plate 1 303 and clamping plate 2 401 to disengage from clamping measuring rod 1, thereby realizing the disassembly of measuring rod 1.
