Description

Technical Field

[0001] This utility model relates to the field of calibration tool technology, and in particular to a quick-change calibration tool. Background Technology

[0002] During use, electronic gauges may experience data deviations due to increased testing frequency and environmental factors. Zeroing restores the gauge's measurement baseline to its initial state, allowing it to be immediately used for the next round of accurate testing without requiring a complex and lengthy calibration process. Since products typically require testing at multiple locations, one electronic gauge usually tests one testing point. This necessitates multiple zeroing gauge changes to calibrate the corresponding electronic gauge, making it difficult for testing stations to adapt to the fast-paced automated production lines. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a quick-change zeroing gauge that can quickly complete the zeroing of multiple electronic gauges and quickly replace the corresponding zeroing block when changing products for testing.

[0005] Furthermore, the aforementioned quick-change calibration fixture also includes a fixing member. The positioning base is provided with a first threaded hole, and the fixing member has a screw. The screw passes through the integrated base and is threadedly connected to the first threaded hole. The fixing member abuts against the top surface of the integrated base.

[0006] Furthermore, the integrated base is provided with a clearance hole for avoiding the screw.

[0007] Furthermore, the fastener also includes a pressure block, which is connected to the screw and abuts against the top surface of the integrated base. The side wall of the pressure block is provided with anti-slip texture.

[0008] Furthermore, the clearance hole and the screw are fitted with a clearance.

[0009] Furthermore, the positioning base is provided with a mounting hole, and a second threaded hole and a first positioning hole are provided around the mounting hole.

[0011] Furthermore, the zeroing block includes a zeroing part and a positioning part. The zeroing part is provided with a zeroing surface for zeroing, and the second assembly hole and the second pin hole are located in the positioning part.

[0012] Furthermore, the zero-calibration part is a rectangular body, and the side walls and top surface of the rectangular body are both zero-calibration surfaces. Alternatively, the zeroing unit may be composed of multiple cylinders, with the cylinders arranged in a manner where the middle is higher than the two sides, and the top surface of each cylinder is the zeroing surface.

[0017] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0018] Because the products require testing at multiple locations, typically one electronic gauge is used to test one testing point. This necessitates multiple changes of calibration gauges to zero the corresponding electronic gauges, making it difficult for the testing station to adapt to the fast-paced automated production line. In this embodiment, positioning areas 22 are set on the integrated base 2 according to the testing points of different products, and the corresponding calibration blocks 3 are positioned on the positioning areas 22 to complete the zeroing of all electronic gauges at once. Furthermore, the integrated base 2, using linear bearings 11, can not only be accurately mounted on the positioning base 1, but also allows for quick assembly and disassembly between the integrated base 2 and the positioning base 1.

[0019] Please refer to Figures 1 to 3 As shown, this utility model provides a quick-change calibration tool, which includes a positioning base 1 and an integrated base 2. The positioning base 1 is provided with a linear bearing 11, and the integrated base 2 is provided with a pin 21 that is inserted into the linear bearing 11. The top surface of the integrated base 2 is provided with multiple positioning areas 22 for positioning and placing the calibration block 3.

[0020] Working principle: Based on the detection points of different products, corresponding positioning areas 22 are set on the integrated base 2, and the corresponding zeroing blocks 3 are positioned on the positioning areas 22 to complete the zeroing of all electronic inspection tools at one time. When changing products for inspection, only the integrated base 2 needs to be replaced. The integrated base 2 is inserted into the linear bearing 11 through the pin 21, and the linear bearing 11 guides the movement direction of the integrated base 2, which not only ensures the installation position of the integrated base 2 on the positioning base 1, but also enables the quick replacement of the integrated base 2.

[0021] In some implementations, please refer to Figure 1 and Figure 3As shown, a quick-change calibration fixture also includes a fixing member 4. The positioning base 1 has a first threaded hole 12. The fixing member 4 has a screw 41, which passes through a clearance hole 23 on the integrated base 2 and is threadedly connected to the first threaded hole 12. The fixing member 4 abuts against the top surface of the integrated base 2. The fixing member 4 uses the screw 41 to be threadedly connected to the first threaded hole 12 to abut against the top surface of the integrated base 2, preventing the integrated base 2 from moving on the positioning base 1 without human intervention.

[0022] Preferably, the clearance hole 23 and the screw 41 are fitted with a clearance to allow the screw 41 to pass quickly through the integrated base 2.

[0023] In some embodiments, the fixing member 4 further includes a pressure block 42, which is connected to the screw 41. The pressure block 42 abuts against the top surface of the integrated base 2, and the side wall of the pressure block 42 is provided with anti-slip texture. The fixing member 4 abuts against the top surface of the integrated base 2 through the pressure block 42, and the side wall of the pressure block 42 is provided with anti-slip texture to facilitate the operator to rotate the screw 41.

[0024] In some implementations, please refer to Figure 3 As shown, the positioning base 1 has a mounting hole 13, and a second threaded hole 14 and a first positioning hole 15 arranged around the mounting hole 13. The linear bearing 11 has a first assembly hole 111 adapted to the second threaded hole 14, and a first pin hole 112 adapted to the first positioning hole 15. The linear bearing 11 is positioned on the positioning base 1 by a pin passing through the first pin hole 112 and the first positioning hole 15 in sequence. Then, the linear bearing 11 is threaded through the first assembly hole 111 and the second threaded hole 14 by a screw, thereby fixing the linear bearing 11 in the mounting hole 13 of the positioning base 1.

[0025] In some implementations, please refer to Figure 2 and Figure 4 As shown, the positioning area 22 is provided with a third threaded hole 221 and a second positioning hole 222. The zeroing block 3 is provided with a second assembly hole 31 that matches the third threaded hole 221, and a second pin hole 32 that matches the second positioning hole 222. The zeroing block 3 is positioned in the positioning area 22 by a pin passing through the second pin hole 32 and the second positioning hole 222 in sequence. Then, the zeroing block 3 is threadedly connected to the third threaded hole 221 by a screw passing through the second assembly hole 31, thereby fixing the zeroing block 3 in the positioning area 22.

[0026] In some implementations, please refer to Figure 5As shown, the zeroing block 3 includes a zeroing part 33 and a positioning part 34. The zeroing part 33 is provided with a zeroing surface 331 for zeroing, and the second mounting hole 31 and the second pin hole 32 are located in the positioning part 34. The zeroing block 3 is assembled with the integrated base 2 through the positioning part 34, and the electronic gauge completes the zeroing through the zeroing surface 331 on the zeroing part 33.

[0027] In some implementations, please refer to Figure 5 As shown, the zeroing part 33 is a rectangular body, and the side walls and top surface of the rectangular body are both zeroing surfaces 331. The zeroing part 33 of the rectangular body is used for the three-axis zeroing of electronic inspection tools.

[0028] In some embodiments, the zeroing section 33 is composed of multiple cylinders, with the cylinders arranged in a manner where the middle is higher than the two sides. The top surface of each cylinder is the zeroing surface 331. The zeroing surface 331 is used for zeroing the electronic gauge in the vertical direction.

[0029] It is worth noting that the top surfaces of the multiple cylinders are designed to simulate the curved shape of a glass surface.

[0030] In some implementations, the positioning area 22 is set as a groove, which can serve as a foolproof method to facilitate the assembly personnel to assemble the zeroing block 3 onto the integrated base 2.

[0031] In some embodiments, the sidewall of the positioning area 22 abuts against the sidewall of the zeroing block 3 to facilitate the positioning of the zeroing block 3 within the positioning area 22.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
