In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0038] The server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0039] Embodiment 1:

[0040] like Figure 1 As shown, an embodiment of the present application provides a cross-axis detection device, including a base plate 1, a V-shaped support frame 2, a cross-axis 3, a detection component 4, and also includes: a limit plate 5, which can be adjustably mounted on the base plate 1; wherein the limit plate 5 is located at one end of the cross-axis 3, and the detection component 4 is arranged on the opposite side.

[0041] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the cross shaft 3 needs to be inspected, the cross shaft 3 is only installed on the V-shaped support frame 2, and it cannot be guaranteed that the installation position is located in the center, which will lead to inaccurate detection data. The position of the limit plate 5 is determined according to the size of the cross shaft 3. The position of the limit plate 5 from one side of the V-shaped support frame 2 is: half the distance of the V-shaped support frame 2 minus half the distance of the cross shaft 3. After the position of the limit plate 5 is determined, one end of the cross shaft 3 is fitted with the limit plate 5, and a detection component 4 is provided on the opposite side to detect the length of the cross shaft 3.

[0042] Embodiment 2:

[0043] like Figure 1 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: an adjustment groove 16, which is arranged on the base plate 1; a fixing plate 6, which is fixedly connected to the bottom end of the limiting plate 5; wherein the fixing plate 6 is installed on the adjustment groove 16 by fasteners, and the detection component 4 is also provided with a fixing plate 6.

[0044] In this embodiment of the present application, due to the use of the above-mentioned structure, the size of the cross axis 3 may be different. When it is necessary to adjust the position of the limit plate 5 and the detection component 4, the fasteners (such as screws, bolts and pins, etc.) that lock the fixing plate 6 and the adjustment groove 16 are unscrewed, and the position of the limit plate 5 and the detection component 4 can be changed according to the actual size of the cross axis 3. After the position is confirmed, the fasteners are used to lock the fixing plate 6 in the adjustment groove 16. By setting the adjustment groove 16, the position of the limit plate 5 and the detection component 4 can be changed, thereby improving the types of detection cross axis 3 of the detection device.

[0045] Embodiment 3:

[0046] like Figure 1 As shown, in this embodiment, in addition to the structural features of the above-mentioned embodiments, the detection assembly 4 also includes: the detection assembly 4 includes an electric telescopic rod 7, the bottom end of which is fixedly connected to one side of the fixing plate 6; a connecting plate 8, which is fixedly connected to the bottom end of the electric telescopic rod 7; a dial indicator 9, which is fixedly mounted on the connecting plate 8

[0047] Furthermore, a pair of V-shaped support frames 2 is provided, wherein the cross shaft 3 is rotatably installed between the pair of V-shaped support frames 2 .

[0048] In this embodiment of the present application, due to the adoption of the above structure, in order to detect the axial parallelism of the cross shaft 3, only one pair of V-shaped support frames 2 is provided, and the front and rear ends of the cross shaft 3 are installed on each V-shaped support frame 2, and the detection head of the dial indicator 9 of the detection component 4 is fitted with the outer surface of the left shaft, and the cross shaft 3 is rotated so that the right shaft surface contacts the detection head of the dial indicator 9, and the parallelism of the left and right sides of the cross shaft 3 is determined according to the value change of the dial indicator 9. After the left and right sides are detected, the cross shaft 3 is rotated 90° and installed, so that the parallelism of the front and rear ends is also detected. If the detection value is not within the specified tolerance, it is an unqualified workpiece. According to the different sizes of the cross shaft 3, when the height of the inspection component needs to be adjusted, the electric telescopic rod 7 is used to drive the connecting plate 8 to drive the dial indicator 9 to move together, so that cross shafts 3 of various sizes can be detected, and during the driving process of the electric telescopic rod 7, the value change of the dial indicator 9 can be observed to detect the flatness of the end surface.

[0049] Embodiment 4:

[0050] like Figure 1 , Figure 2 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a marking component 10, which is fixedly mounted on the base plate 1; a controller 11, which is fixedly mounted on the marking component 10; wherein the output end of the marking component 10 is located above the cross axis 3.

[0051] Furthermore, the marking assembly 10 includes a support frame 12, which is fixedly mounted on the base plate 1; an electric push rod 13, which is fixedly mounted on the support frame 12; a mounting tube 14, which is fixedly connected to the output end of the electric push rod 13; and a marking pen 15, which is fixedly mounted in the mounting tube 14.

[0052] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the data of the dial indicator 9 and the like will be uniformly recorded by the computer. When the recorded value exceeds the set range, the cross shaft 3 is unqualified, and the computer transmits a signal to the controller 11. The controller 11 drives the electric push rod 13 to start, and the electric push rod 13 drives the installation cylinder 14 to move downward, so that the marker pen 15 marks the surface of the cross shaft 3, thereby facilitating the workers to distinguish between qualified and unqualified cross shafts 3.
