[0015] Please see Figure 1-4 The present invention provides a technical solution: a 3D printing measuring tool for inspecting the dimensions of automotive parts, including a worktable 1, on which a width measuring mechanism 2 and an inner diameter measuring mechanism 3 are provided; The width measuring mechanism 2 includes a moving component 201, a support column 202, a fixed plate 203, a first sliding groove 204, a first lead screw 205, a first sliding block 206, a measuring plate 207, a rubber pad 208, and a displacement sensor 209. The moving component 201 is mounted on the worktable 1. The support column 202 is fixedly mounted on the moving component 201. There are two support columns 202, which are symmetrically arranged. The fixed plate 203 is fixedly mounted on the support column 202. The first sliding groove 204 is formed on the fixed plate 203. One end of the lead screw 205 is rotatably connected to the first sliding groove 204, and the other end of the lead screw 205 extends to the outside of the first sliding groove 204. The first sliding block 206 is disposed in the first sliding groove 204 and is threadedly rotatably connected to the first lead screw 205. There are two first sliding blocks 206 arranged symmetrically. The measuring plate 207 is fixedly disposed on the first sliding block 206. The rubber pad 208 is fixedly disposed on the measuring plate 207. The displacement sensor 209 is disposed on the measuring plate 207.

[0016] The above scheme is adopted: by setting up a workbench 1, a width measuring mechanism 2, and an inner diameter measuring mechanism 3, in use, the workbench 1 can first install and fix the width measuring mechanism 2 and the inner diameter measuring mechanism 3, then the width measuring mechanism 2 can measure the width of automotive parts, and can also measure the outer diameter of shaft-type parts, and then the inner diameter measuring mechanism 3 can measure shaft-type parts. The width measuring mechanism 2 includes a moving component 201, a support column 202, a fixing plate 203, a first sliding groove 204, a first lead screw 205, a first sliding block 206, a measuring plate 207, a rubber pad 208, and a displacement sensor 209. In use, the moving component 201 can drive... The support column 202 is moved to adjust the distance between the two support columns 202, which facilitates the measurement of shaft-like components of different lengths. The shaft-like component is then placed between the two support columns 202 and supported by the fixing plate 203 on the support column 202. Then, the first lead screw 205 is rotated to make the first sliding block 206 slide in the first sliding groove 204, so that the measuring plate 207 on the first sliding block 206 contacts the shaft-like component. Then, the rubber pad 208 can protect the shaft-like component. Then, the outer diameter of the shaft-like component is detected by two displacement sensors 209, and the width of the automotive component can also be detected, reducing the error of manual measurement.

[0017] refer to Figure 3 The inner diameter measuring mechanism 3 includes a mounting base 301, a three-jaw chuck 302, and a connecting plate 303. The mounting base 301 is fixedly mounted on the worktable 1, the three-jaw chuck 302 is fixedly mounted on the mounting base 301, and the connecting plate 303 is fixedly mounted on the three-jaw chuck 302. A displacement sensor 209 is provided on the connecting plate 303.

[0018] The above solution involves setting up a mounting base 301, a three-jaw chuck 302, and a connecting plate 303. During use, the mounting base 301 fixes the three-jaw chuck 302 onto the worktable 1. When it is necessary to detect the inner diameter of a shaft-type component, the shaft-type component is placed outside the connecting plate 303 of the three-jaw chuck 302, allowing the three connecting plates 303 to enter the shaft-type component. Then, the three-jaw chuck 302 drives the connecting plate 303 to rotate, causing the displacement sensor 209 on the connecting plate 303 to contact the inner wall of the shaft-type component, thereby detecting the inner diameter of the shaft-type component.

[0019] refer to Figure 4 The movable component 201 includes a second sliding groove 2011, a second lead screw 2012, a second sliding block 2013, and a mounting plate 2014. The second sliding groove 2011 is formed on the worktable 1. One end of the second lead screw 2012 is rotatably connected to the second sliding groove 2011, and the other end of the second lead screw 2012 extends to the outside of the second sliding groove 2011. The second sliding block 2013 is disposed in the second sliding groove 2011 and is threadedly rotatably connected to the second lead screw 2012. There are two second sliding blocks 2013, which are symmetrically arranged. The mounting plate 2014 is fixedly disposed on the second sliding block 2013, and the support column 202 is fixedly disposed on the mounting plate 2014.

[0020] The above solution is adopted: by setting a second sliding groove 2011, a second lead screw 2012, a second sliding block 2013 and a mounting plate 2014, when it is necessary to adjust the spacing of the mounting columns, the second lead screw 2012 drives the second sliding block 2013 to move in the second sliding groove 2011, thereby driving the mounting plate 2014 to move, which facilitates the adjustment of the spacing of the support columns 202.

[0021] refer to Figure 1 The workbench 1 is equipped with a display screen 4, which is connected to the displacement sensor 209.

[0022] The above solution is adopted: by setting up a display screen 4, when in use, the display screen 4 is electrically connected to the displacement sensor 209, which can convert the distance signal sensed by the displacement sensor 209 into an electrical signal and transmit it to the display screen 4, so that the staff can understand the test results.

[0023] refer to Figure 2 The workbench 1 has two limit grooves 5 arranged symmetrically. A limit rod 6 is fixedly installed inside the limit groove 5. A limit block 7 is slidably connected to the limit rod 6. The limit block 7 is fixedly connected to the mounting plate 2014.

[0024] The above solution is adopted: by setting the limiting groove 5, the limiting rod 6 and the limiting block 7, when the mounting plate 2014 moves, the limiting block 7 can be driven to move in the limiting groove 5. Through the cooperation of the limiting block 7 and the limiting rod 6, the movement of the mounting plate 2014 can be limited.

[0025] refer to Figure 1 A handle 8 is fixedly provided at one end of both the first lead screw 205 and the second lead screw 2012.

[0026] The above solution is adopted: by setting handle 8, when in use, handle 8 can provide a force point for the operator to rotate the first lead screw 205 and the second lead screw 2012.

[0027] The working principle of this utility model: In use, the moving component 201 can move the support column 202, adjusting the distance between the two support columns 202 to facilitate the measurement of shaft-like components of different lengths. The shaft-like component is then placed between the two support columns 202, supported by the fixing plate 203 on the support columns 202. The first lead screw 205 is then rotated, causing the first sliding block 206 to slide in the first sliding groove 204, bringing the measuring plate 207 on the first sliding block 206 into contact with the shaft-like component. The rubber pad 208 protects the shaft-like component. Two displacement sensors 209 detect the outer diameter of the shaft-like component and can also detect the width of automotive components, reducing errors from manual measurement. The three-jaw chuck 302 is fixed to the worktable 1 via the mounting base 301. When the inner diameter of the shaft-like component needs to be measured, the shaft-like component is placed into the connecting jaw of the three-jaw chuck 302. Outside the connecting plate 303, the three connecting plates 303 are inserted into the shaft-like components. Then, the three-jaw chuck 302 drives the connecting plates 303 to rotate, causing the displacement sensor 209 on the connecting plate 303 to contact the inner wall of the shaft-like components, thereby detecting the inner diameter of the shaft-like components. When it is necessary to adjust the spacing of the mounting columns, the second lead screw 2012 drives the second sliding block 2013 to move in the second sliding groove 2011, thereby driving the mounting plate 2014 to move, thus facilitating the adjustment of the spacing of the support columns 202. Then, the display screen 4 is electrically connected to the displacement sensor 209, which can convert the distance signal sensed by the displacement sensor 209 into an electrical signal and transmit it to the display screen 4, so that the staff can understand the detection results. Then, when the mounting plate 2014 moves, it can drive the limiting block 7 to move in the limiting groove 5. Through the cooperation of the limiting block 7 and the limiting rod 6, the movement of the mounting plate 2014 can be limited.
