Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detection tooling fixtures, in particular to a clamping structure of a shaft straightness detection tooling. Background Art
[0002] Shaft workpieces, such as transmission shafts and half shafts, are often bent and deformed during the production process due to processes such as heat treatment and surface quenching. Therefore, it is necessary to detect the straightness of these workpieces and, if necessary, straighten them.
[0003] Traditional inspection methods typically rely on measuring tools like dial indicators, but these methods suffer from inefficiency and difficulty with lateral movement when working with long shafts. Furthermore, a single dial indicator can only detect the straightness of a specific location on the workpiece, requiring frequent movement to obtain comprehensive results, further reducing inspection efficiency. Therefore, a clamping structure for a shaft straightness inspection tool was proposed. Utility Model Content

[0029] See also Figure 1-3 A clamping structure for a shaft straightness detection tool comprises two main body side plates 2 and a follower sliding component, wherein the follower sliding component is arranged on the inner side of the two main body side plates 2.
[0030] A common storage bottom shell 1 is fixedly installed at the bottom of the two main body side panels 2. A detection measuring scale 6 is set on the front of the storage bottom shell 1. A spring telescopic shaft 8 is set on the left side of the right main body side panel 2, and a clamping plate 9 is set on the left side of the spring telescopic shaft 8.
[0031] In this embodiment, fixing bolts 11 are provided at both ends of the detection scale 6. The two fixing bolts 11 are respectively fixedly installed on the front of the main body side panel 2. A zero plate 3 is fixedly installed on the inner side of the main body side panel 2 on the left. The zero plate 3 is collinear with the left end of the detection scale 6.
[0032] It should be noted that the zero plate 3 on the left is collinear with the left end of the detection scale 6, providing a clear zero reference for detection. This design simplifies the calibration process before detection, so that each detection can start from the same reference, avoiding errors caused by inaccurate calibration.
[0033] In this embodiment, the spring telescopic shaft 8 is fixedly installed on the left side of the right main body side plate 2, and the left end of the spring telescopic shaft 8 is fixedly installed with a clamping plate 9, which can be fitted with the zero plate 3.
[0034] It should be noted that the design of the spring telescopic shaft 8 allows the clamping plate 9 to be adaptively adjusted according to the diameter of the shaft rod. This adaptive feature not only ensures that the shaft rod can be firmly clamped, but also reduces the errors caused by clamping too tightly or too loosely, thereby improving the accuracy of detection.
[0035] The follower sliding component includes two positioning rods 5, which are respectively arranged on the front and rear sides of the main body side plate 2. Connecting sliders 12 are provided on the opposite sides of the two positioning rods 5. The two connecting sliders 12 are movably installed on the front and rear sides of the clamping plate 9.
[0036] In this embodiment, height slide grooves 4 are provided on the front and rear sides of the two main body side panels 2, and positioning bolts 7 are fixedly installed on the left and right ends of the two positioning rods 5. Both sets of positioning bolts 7 are slidably installed on the inner side of the height slide grooves 4.
[0037] It should be noted that the height position of the clamping plate 9 can be easily adjusted by sliding the positioning bolts 7 at both ends of the positioning rod 5 in the height slide groove 4. This design enables the tooling to adapt to shafts of different lengths, thereby improving the flexibility and applicability of the tooling.
[0038] In this embodiment, positioning grooves 10 are provided on the front and rear sides of the clamping plate 9. Connecting sliders 12 are clamped on the inner sides of the two positioning grooves 10. The connecting sliders 12 are connected to the positioning rods 5 and can slide up and down.
[0039] It should be noted that the connecting slider 12 slides up and down in the positioning slot 10, so that the clamping plate 9 can be easily adjusted in height. This design allows the operator to quickly adapt to shafts of different lengths without replacing or adjusting other complex components, thereby improving the flexibility and ease of use of the tooling.
[0040] In this embodiment, limiting slots 13 are provided on opposite sides of the two positioning rods 5 , and connecting sliders 12 connected to the clamping plate 9 are clamped on the inner sides of the two limiting slots 13 , and the connecting sliders 12 can slide back and forth.
[0041] It should be noted that the connecting slider 12 slides back and forth in the limiting slide groove 13, so that the clamping plate 9 can be easily adjusted to the left and right (or front and back, depending on the tooling layout). This design allows the operator to quickly adjust the clamping position of the clamping plate 9 according to the specific size and position of the shaft, thereby improving the flexibility and ease of use of the tooling.
[0042] The close fit between the limiting slide groove 13 and the connecting slider 12, as well as the firm connection between the connecting slider 12 and the clamping plate 9, together form a stable clamping system. This design ensures that the clamping plate 9 will not shake or deflect when clamping the shaft, thereby improving the stability and reliability of the clamping.
[0043] The beneficial effects of the above embodiment are:
[0044] By adopting the sliding cooperation design of the height slide 4 and the positioning bolt 7, and the up and down sliding of the connecting slider 12 and the positioning slide 10, and the front and back sliding design with the limit slide 13, these designs allow the operator to quickly adjust the height, front and back position and clamping range of the clamping plate 9 to adapt to shafts of different sizes and shapes, greatly improving the flexibility and efficiency of detection. At the same time, the design of the spring telescopic shaft 8 provides an adaptive clamping force for the clamping plate 9, which can automatically adjust the clamping tightness according to shafts of different diameters to ensure that the shaft remains stable and does not shake during the detection process. In addition, the stable connection between the positioning rod 5 and the connecting slider 12 also enhances the overall stability of the clamping structure.
