[0002] In the shipbuilding industry, steel tape measures are the most widely used and largest number of geometric measurement tools. As a commonly used measuring tool, steel tape measures are mainly used to measure the length, width and thickness of various plates and pipes during shipbuilding. Whether it is steel plate cutting, assembly forming or mounting splicing, the dimensional measurement data provided by steel tape measures are indispensable. Therefore, the accuracy of steel tape measures is very important in the shipbuilding process and is directly related to the quality and safety of ships. In order to ensure the stability of the measurement performance of steel tape measures, accurate and reliable values, it is necessary to conduct regular metrological verification.

[0034] According to the present invention, an auxiliary positioning tool for a laser marking machine is provided, which includes a support member 10 and a clamping assembly.

[0035] Hereinafter, the specific structures of the above-mentioned components of the auxiliary positioning tool for the laser marking machine according to the present embodiment will be described.

[0036] In this embodiment, if Figure 1As shown, the support member 10 includes a first support portion 101 and a second support portion 102 that are opposite to each other and spaced apart. Preferably, the first support portion 101 and the second support portion 102 are parallel to each other. An adjustment hole 1021 is provided on the second support portion 102. The adjustment hole 1021 is formed as a through hole structure that passes through the second support portion 102. The adjustment hole 1021 can be a through hole in a circular or rectangular shape. Preferably, the axial extension direction of the adjustment hole 1021 is the same as the spacing arrangement direction of the first support portion 101 and the second support portion 102.

[0037] In this implementation, if Figure 1 As shown, the clamping assembly includes a clamping member 20 and an elastic member 30. The clamping member 20 can be formed into a block structure. The clamping member 20 is arranged between the first support portion 101 and the second support portion 102 and encloses a clamping space 13 with the first support portion 101. The steel tape measure is arranged in the clamping space 13 and is clamped and fixed by the clamping member 20 and the first support portion 101. Specifically, a protruding sliding portion 21 is formed on one side of the clamping member 20 away from the first support portion 101. The sliding portion 21 is formed into a rod-shaped structure. The moving part 21 is inserted into the adjustment hole 1021, so that the clamping member 20 can slide relative to the supporting member 10, and the elastic member 30 is sleeved on the outer wall of the sliding part 21, so that the elastic member 30 is squeezed in the process of driving the sliding part 21 to slide toward the second supporting part 102, and when the force driving the sliding part 21 to slide is released, the elastic member 30 is relatively extended to push the clamping member 20 to move in the direction close to the first supporting part 101, so as to achieve a firm clamping of the steel tape measure, thereby improving the marking quality.

[0038] In the present application, the volume of the clamping space 13 is adjusted by adjusting the relative position of the sliding part 21 and the second supporting part 102, so as to realize fast and accurate positioning of large quantities of steel tapes of different sizes, meet the marking requirements of the laser marking machine, and make the numbers on the steel tapes be marked at the specified positions, thereby improving the marking quality, thereby ensuring that the management number information is marked complete and unambiguous, facilitating subsequent management, and the clamping and positioning operation is convenient and practical, ensuring the stable measurement performance of the steel tape and accurate and reliable values, while improving the efficiency of measurement and calibration of the steel tape during shipbuilding.

[0039] In this embodiment, one end of the steel tape measure is formed into an arc surface, and the end opposite to the arc surface is formed into a plane, which abuts against the side of the first support part 101 facing the second support part 102, and the clamping part abuts against the arc surface, thereby ensuring that the clamping and positioning of the steel tape measure are accurate and reliable, and ensuring the marking quality.

[0040] Furthermore, in this embodiment, if Figure 1As shown, along the extension and retraction direction of the elastic member 30, both ends of the elastic member 30 are in contact with the clamping member 20 and the second support portion 102 respectively, to ensure that the sliding portion 21 can compress the elastic member 30 when sliding in the direction close to the second support portion 102, thereby achieving effective clamping of the steel tape measure.

[0041] In this embodiment, the elastic member 30 is a compression spring. In a preferred implementation, the elastic member 30 can be compressed to a length of 8 cm relative to an initial state without force, thereby meeting the use requirements of steel tape measures of different specifications.

[0042] In this embodiment, if Figure 1 The sliding portion 21 passes through the adjustment hole 1021 to form an operating portion 23 on the side of the second support portion 102 away from the clamping member 20. The operating portion 23 can be a handle in a rod-shaped or ring-shaped shape. The operating portion 23 is pulled to drive the clamping member 20 to slide in a direction close to the second support portion 102, thereby squeezing the elastic member 30 to increase the clamping space 13, and then the steel tape measure is placed in the clamping space 13, and the operating portion 23 is released. The elastic member 30 pushes the clamping member 20 to move in a direction close to the first support portion 101 to achieve the clamping and positioning of the steel tape measure.

[0043] Further, in a preferred embodiment, as Figure 1 As shown, a convex limiting portion 22 is formed at one end of the operating portion 23 facing the second support portion 102. The limiting portion 22 can be a ring structure or a convex block structure, so as to prevent the operating portion 23 from entering the adjustment hole 1021 when the elastic member 30 pushes the clamping member 20 to move toward the direction close to the first support portion 101, causing the support member 10 and the clamping assembly to separate.

[0044] In this embodiment, if Figure 1 As shown, the sliding part 21 is formed as a rod-shaped structure, and a plurality of sliding parts 21 are provided. The plurality of sliding parts 21 are arranged at intervals along a direction perpendicular to the length thereof, and the elastic member 30 is provided one-to-one with the sliding part 21 to improve the reliability of clamping the steel tape measure.

[0045] Furthermore, in this embodiment, if Figure 1As shown, the clamping member 20 is formed into a strip structure, the extension direction of the clamping member 20 is parallel to the sliding direction of the sliding part 21, and along the length direction of the clamping member 20, the clamping member 20 includes a plurality of detachably connected clamping parts, and the sliding part 21 is arranged one by one with the clamping part, that is, the clamping member 20 is formed into a split structure, and a plurality of clamping parts are spliced ​​together, and the clamping part can be a block structure, and adjacent clamping parts can be detachably connected by means of clamping or the like. The elastic coefficient of each elastic member 30 in the plurality of elastic members 30 is different, that is, the magnitude of the force applied to drive each elastic member 30 to compress is different, so that the clamping force of the clamping part corresponding to each elastic member 30 is different. In all the elastic members 30, the elastic members 30 are arranged in sequence according to the magnitude of the elastic coefficient, so that the clamping force can be adjusted according to the size specification of the steel tape measure to ensure accurate and reliable positioning. For example, when the required clamping space 13 is large, the clamping part connected to the elastic member 30 with a larger elastic coefficient can be separated from the other clamping parts.

[0046] In addition, in this embodiment, Figure 1 As shown, the support member 10 also includes a third support portion 103 and a fourth support portion 104 which are arranged opposite to each other, the first support portion 101, the second support portion 102, the third support portion 103 and the fourth support portion 104 are all formed as a strip-shaped plate structure, the first support portion 101, the third support portion 103, the second support portion 102 and the fourth support portion 104 are connected in sequence to form a frame structure, and the clamping member 20 is arranged in the frame structure.

[0047] Furthermore, in this implementation, if Figure 1 As shown, a protruding guide portion 11 is provided on the side of the third support portion 103 and / or the fourth support portion 104 facing the clamping member 20. The guide portion 11 is formed as a strip-shaped rod-like structure extending along the sliding direction of the sliding portion 21. A guide groove for the guide portion 11 to extend into is provided on the side wall of the clamping member 20, so that the clamping member 20 can slide back and forth along the extension direction of the guide portion 11, thereby ensuring the sliding path of the sliding portion 21 and improving the clamping stability of the clamping member 20 on the steel tape measure.

[0048] In this embodiment, the support member 10 is placed on the processing platform of the laser marking machine, and a plurality of fixing holes arranged in an array are provided on the processing platform, and the plurality of fixing holes can be arranged in a rectangular array; further, the auxiliary positioning tool for the laser marking machine also includes a positioning member, the fixing hole is a threaded hole, and the positioning member is a screw threadedly connected to the fixing hole. A positioning hole 12 is opened on the support member 10, and the positioning member is a through hole structure. The positioning member passes through the positioning hole 12 and the fixing hole in sequence, so that the support member 10 is fixed on the processing platform.

[0049] In a preferred embodiment, Figure 1As shown, the positioning hole 12 is formed as a long hole, and a plurality of positioning holes 12 are provided on the support member 10. Preferably, the first support member 10, the second support member 10, the third support member 10 and the fourth support member 10 are all provided with positioning holes 12 to meet different marking requirements, wherein at least some of the length directions of the positioning holes 12 are perpendicular to each other, thereby ensuring that the support member 10 can be installed on processing platforms of different sizes.

In this way, the volume of the clamping space can be adjusted by adjusting the relative position of the sliding portion and the second supporting portion. The elastic member can firmly clamp the steel tape measure to achieve fast and accurate positioning of large quantities of steel tape measures of different sizes, meet the marking requirements of the laser marking machine, and make the number on the steel tape measure be marked at the specified position, thereby ensuring that the management number information is marked completely and without ambiguity, facilitating subsequent management, and the clamping and positioning operation is convenient, ensuring that the metrological performance of the steel tape measure is stable and the numerical value is accurate and reliable, while improving the efficiency of metrological calibration of the steel tape measure during shipbuilding.
