Embodiment

[0044] Refer to Figures 1-3, A steel straightedge positioning tooling. The positioning tooling is used to adjust the relative positions of a standard ruler (i.e., a third-class metal line scale) and a ruler to be inspected (i.e., the steel straightedge to be detected) during the calibration of the steel straightedge. It includes a workbench 1, a bottom plate 2, and an adjustment mechanism 3. Specifically, the workbench 1 is a plate-like structure, and the top of the workbench 1 is a smooth plane, which is beneficial to improving the smooth placement and movement of the ruler to be inspected and the standard ruler on the workbench 1, and reducing the operation obstacles caused by the uneven surface or burrs of the workbench 1. The bottom plate 2 is arranged at one end of the workbench 1, and the bottom plate 2 is fixedly connected to the workbench 1, that is, the contact surface and the installation surface of the bottom plate 2 and the workbench 1 are both flat surfaces, so that the positioning tooling maintains a horizontal state on the workbench 1. The adjustment mechanism 3 is arranged on the bottom plate 2, and the adjustment mechanism 3 is used to finely adjust the positions of the ruler to be inspected and the standard ruler. The adjustment mechanism 3 is fixedly connected to the bottom plate 2 by means of bolts and nuts, so that the adjustment mechanism 3 can be quickly disassembled and assembled with the bottom plate 2.

[0045] Among them, the adjustment mechanism 3 includes a first adjustment module 31 and a second adjustment module 32. The first adjustment module 31 is fixedly arranged on the bottom plate 2 and is used to adjust the position of the standard ruler or the ruler to be inspected. The second adjustment module 32 is arranged on the bottom plate 2 and is located on one side of the first adjustment module 31 and is used to adjust the position of the ruler to be inspected or the standard ruler. The second adjustment module abuts against the first adjustment module 31, making the structure more compact and convenient for operation. Preferably, the first adjustment module 31 and the second adjustment module 32 are arranged alternately on the bottom plate 2, so as to facilitate the staff to distinguish the two adjustment modules and avoid confusion, thereby improving the work efficiency and detection accuracy.

[0046] In this embodiment, during the calibration of the steel straightedge, the standard ruler and the ruler to be inspected are placed on the workbench 1, so that the end edge of the standard ruler and the end edge of the ruler to be inspected respectively abut against the first adjustment module 31 and the second adjustment module 32 in the adjustment mechanism 3, and the side edge of the ruler to be inspected is attached to the side edge of the standard ruler. At this time, observe the relative positions of the ruler to be inspected and the standard ruler through the software interface of the calibrator, and at the same time, by adjusting the first adjustment module 31 and the second adjustment module 32 in the adjustment mechanism 3, continuously finely adjust the positions of the standard ruler and the ruler to be inspected on the workbench 1 until the end edge of the ruler to be inspected is aligned with the "0" scale line of the standard ruler, and complete the positioning of the standard ruler and the ruler to be inspected. By setting the adjustment mechanism 3, continuously finely adjust the relative positions of the standard ruler and the ruler to be inspected, solve the shortcoming that the alignment position of the standard ruler and the ruler to be inspected is not accurate enough, and achieve the technical effect of quickly aligning and positioning the standard ruler and the ruler to be inspected.

[0047] In this embodiment, the first adjustment module 31 includes a first support base 311, a first lead screw 312, and a first push frame 313. Specifically, the first support base 311 is disposed on the base plate 2 and is used for supporting the installation of components. The first lead screw 312 is disposed within the first support base 311, and both ends of the first lead screw 312 are rotatably connected to the first support base 311, such that the first lead screw 312 can be rotated within the first support base 311. The first push frame 313 is movably disposed within the first support base 311, and the first push frame 313 is threadedly connected to the first lead screw 312. Rotating the first lead screw 312 can drive the first push frame 313 to move. Among them, the first push frame 313 is a block structure bent towards the base plate 2 to reduce the gap with the base plate 2. For example, one end of the first push frame 313 abuts against the edge of the standard ruler. When moving the first push frame 313, the standard ruler can be moved for position fine-tuning.

[0048] In this embodiment, the second adjustment module 32 includes a second support base 321, a second lead screw 322, and a second push frame 323. Specifically, the second support base 321 is disposed on the base plate 2 and is located on one side of the first support base 311, that is, the second support base 321 has the same function as the first support base 311 and is staggered with the first support base 311 on the base plate 2. The second lead screw 322 is disposed within the second support base 321, and both ends of the second lead screw 322 are rotatably connected to the second support base 321, such that the second lead screw 322 can be rotated within the second support base 321. The second push frame 323 is movably disposed within the second support base 321, and the second push frame 323 is threadedly connected to the second lead screw 322. Rotating the second lead screw 322 can drive the second push frame 323 to move. The second push frame 323 has an overall L-shaped structure. Among them, the length of the connecting member 3231 is greater than the length of the standard ruler push frame to prevent the second push frame 323 from colliding with the standard ruler push frame during movement. For example, one end of the second push frame 323 abuts against the edge of the inspected ruler. When moving the second push frame 323, the inspected steel straight ruler can be driven to move.

[0049] In some preferred embodiments, the pitch of the threads on the first lead screw 312 and the second lead screw 322 is less than 0.7 mm, that is, when the first lead screw 312 and the second lead screw 322 rotate one week, the corresponding first push frame 313 and second push frame 323 move 0.7 mm on the lead screw respectively, so as to improve the transmission accuracy.

[0050] In some preferred embodiments, keycaps 4 are provided at one end of each of the first lead screw 312 and the second lead screw 322. The keycaps 4 are fixedly connected to one end of the first lead screw 312 and the second lead screw 322, and anti-slip stripes are provided on the surface of the keycaps 4. Staff can rotate the keycaps 4 to rotate the first lead screw 312 and the second lead screw 322.

[0051] In this embodiment, the adjusting mechanism 3 further includes two auxiliary rod groups 33. The two auxiliary rod groups 33 are respectively arranged in the first adjusting module 31 and the second adjusting module 32, that is, the two auxiliary rod groups 33 respectively pass through the first pushing frame 313 and the second pushing frame 323 and are movably connected to the first pushing frame 313 and the second pushing frame 323 respectively, so as to provide more support points for the first adjusting module 31 and the second adjusting module 32, enabling the standard ruler pushing frame and the ruler to be inspected pushing frame to move smoothly.

[0052] In this embodiment, the second pushing frame 323 includes a connecting piece 3231, an abutting block 3232 and a limiting block 3233. Specifically, the connecting piece 3231 is arranged in the second support seat 321. One end of the connecting piece 3231 is threadedly connected to the second lead screw 322. By rotating the second lead screw 322, the connecting piece 3231 is driven to move in the second support seat 321. The abutting block 3232 is arranged at the end of the connecting piece 3231 far from the end threadedly connected to the second lead screw 322, and the abutting block 3232 is perpendicular to the connecting piece 3231 to increase the adjustment distance of the ruler to be inspected. The bottom end of the limiting block 3233 is in contact with the bottom plate 2 to reduce the gap with the workbench 1. The limiting block 3233 abuts against the end edge of the ruler to be inspected, so that the limiting block 3233 can push the ruler to be inspected to make fine adjustments following the movement of the abutting block 3232. Preferably, for facilitating the positioning of a steel straight ruler with a relatively long length (for example, exceeding one meter), a through groove is provided on the abutting block 3232, and the limiting block 3233 is movably arranged in the through groove. For example, when the length of the ruler to be inspected exceeds one meter, the limiting block 3233 in the through groove is pulled out of the through groove to keep the gap between the bottom end of the ruler to be inspected moving assembly and the workbench 1 open. The ruler to be inspected is placed at the lower end of the limiting block 3233, and then by adjusting the first adjusting module 31, the position of the standard ruler on the workbench 1 is finely adjusted to align the standard ruler with the ruler to be inspected without moving the ruler to be inspected, so as to facilitate the inspection of the ruler to be inspected with a length exceeding one meter.

[0053] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
