[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0020] The metal stretching detection device according to the embodiment of the utility model is described below with reference to the accompanying drawings.

[0021] like Figure 1-Figure 3 As shown, the metal stretching detection device of the embodiment of the utility model may include a workbench 1, a stretcher 2, a buffer assembly 3, a clamping assembly 4 and a controller 5.

[0022] A support platform 10 is arranged on the workbench 1 , and the stretcher 2 is arranged on the support platform 10 .

[0023] It should be noted that the stretcher 2 described in this embodiment is a stretching device such as an electric telescopic rod or a hydraulic cylinder commonly found on the market, so as to achieve the stretching of metal parts.

[0024] One end of the buffer component 3 is fixedly connected to the workbench 1 , and the other end of the buffer component 3 is slidably connected to the extension shaft of the stretcher 2 .

[0025] It can be understood that, by setting the buffer component 3, the impact force generated by the device after the metal part is broken can be alleviated, thereby reducing the damage to the device caused by the impact, reducing the maintenance cost of the device, and increasing the service life of the device.

[0026] The clamping assembly 4 may include a plug-in sleeve 40 , a clamping mechanism 41 and a linkage mechanism 42 .

[0027] Wherein, a plug hole 400 and an insertion hole 401 are opened at both ends of the plug-in tube 40 , the extended shaft of the stretcher 2 is slidably connected to the insertion hole 401 , and the clamping mechanism 41 is arranged in the plug-in tube 40 .

[0028] It should be noted that the stretcher 2, buffer assembly 3 and clamping assembly 4 described in this embodiment are provided in pairs and are symmetrically arranged on the workbench 1, so that the two ends of the metal part can be stretched to improve the stretching effect of the device.

[0029] One end of the linkage mechanism 42 is rotationally connected to the clamping mechanism 41, the other end of the linkage mechanism 42 is fixedly connected to the extension shaft of the stretcher 2, and the other end of the linkage mechanism 42 abuts against the plug-in tube 40. The controller 5 is arranged on the workbench 1, and the controller 5 is connected to the stretcher 2.

[0030] It can be understood that through the setting of the joint control mechanism 42, the extended shaft of the stretcher 2 can drive the joint control mechanism 42 when it retracts, thereby controlling the clamping mechanism 41 to clamp the metal parts. The operation is simple, the labor intensity of relevant personnel is reduced, and the work efficiency of metal stretching detection is improved.

[0031] Specifically, in the actual operation process, the relevant personnel insert the two ends of the metal part into the clamping mechanism 41 in the plug-in tube 40 respectively, thereby starting the controller 5 to pre-clamp the metal part, and in the process of pre-clamping, the extended shaft of the stretcher 2 moves in the plug-in tube 40, thereby controlling the movement of the interlocking mechanism 42, and the interlocking mechanism 42 controls the clamping mechanism 41 to clamp the metal part, and the interlocking mechanism 42 abuts against the plug-in tube 40, thereby completing the pre-clamping of the metal part, and the relevant personnel then operate the controller 5 to make the stretcher 2 stretch the metal part, and the controller 5 performs detection based on the tension of the stretcher 2, and transmits the detection result to the display port (not shown in the figure) for the relevant personnel to view the stretching value, thereby completing the stretching detection of the metal part, so that the metal part can be clamped quickly, thereby improving the stretching detection efficiency of the device.

[0032] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the clamping mechanism 41 may include a fixing block 410 , a connecting plate 411 , a clamping block 412 , a control rod 413 and a support rod 414 .

[0033] Among them, the fixed block 410 is fixedly connected to the plug-in tube 40, and a plurality of tooth blocks 4100 are arranged on the fixed block 410, the connecting plate 411 is rotatably connected to the fixed block 410, the clamping block 412 is rotatably connected to the connecting plate 411, and a plurality of tooth blocks 4100 are arranged on the clamping block 412, the control rod 413 is rotatably connected to the connecting plate 411, one end of the linkage mechanism 42 is rotatably connected to the control rod 413, and the clamping block 412 and the control rod 413 are sequentially arranged up and down on the fixed block 410, one end of the support rod 414 is rotatably connected to the fixed block 410, and the other end of the support rod 414 is rotatably connected to the control rod 413.

[0034] It is understandable that, by disposing the tooth block 4100 , the friction force between the clamping block 412 and the fixing block 410 on the metal part can be increased, thereby improving the clamping effect of the device on the metal part.

[0035] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the linkage mechanism 42 may include a slider 420 and a connecting rod 421 .

[0036] The slider 420 is disposed on the extension shaft of the stretcher 2 , and the slider 420 abuts against the plug-in tube 40 , one end of the connecting rod 421 is rotationally connected to the control rod 413 , and the other end of the connecting rod 421 is rotationally connected to the slider 420 .

[0037] It should be noted that the diameter of the slider 420 described in this embodiment is larger than the diameter of the insertion hole 401 , so that the slider 420 abuts against the plug-in tube 40 , thereby achieving the stretching of the metal part by the device.

[0038] In one embodiment of the present invention, Figure 1-Figure 3 As shown, a clamping spring 43 is provided on one side of the fixing block 410 , and the clamping spring 43 abuts against the sliding block 420 .

[0039] It should be noted that the clamping spring 43 described in this embodiment can limit the slider 420 after the metal part is pulled off, thereby preventing the clamping mechanism 41 from rebounding and ejecting the metal part in the clamping mechanism 41, and also preventing the clamping mechanism 41 from moving in the opposite direction to damage the clamping mechanism 41, thereby improving the service life of the device.

[0040] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the buffer assembly 3 may include a buffer box 30 , a buffer plate 31 and a buffer spring 32 .

[0041] Among them, the buffer box 30 is slidably connected to the extending shaft of the stretcher 2, the buffer plate 31 is slidably set in the buffer box 30, and the buffer plate 31 is fixedly connected to the extending shaft of the stretcher 2, the buffer spring 32 is sleeved on the extending shaft of the stretcher 2, one end of the buffer spring 32 is connected to the buffer box 30, and the other end of the buffer spring 32 abuts against the buffer plate 31.

[0042] It can be understood that, by setting the buffer component 3, the impact force generated by the device after the metal part is broken can be alleviated, thereby reducing the damage to the device caused by the impact, reducing the maintenance cost of the device, and increasing the service life of the device.

[0043] Specifically, in the actual operation process, the relevant personnel insert the two ends of the metal part into the clamping mechanism 41 in the plug-in tube 40 respectively, thereby starting the controller 5 to pre-clamp the metal part, and in the process of pre-clamping, the extended shaft of the stretcher 2 moves in the plug-in tube 40, thereby controlling the movement of the slider 420 and the connecting rod 421, and the connecting rod 421 drives the control rod 413 to move obliquely downward, thereby driving the clamping block 412 to move obliquely downward and clamp the metal part, and after clamping, the slider 420 abuts against the plug-in tube 40, thereby completing the pre-clamping of the metal part, and the relevant personnel operate the controller 5 again to make the stretcher 2 continue to stretch the metal part, and the controller 5 detects according to the tension of the stretcher 2, and transmits the detection result to the display port for the relevant personnel to view the stretching value, thereby completing the stretching detection of the metal part, so that the metal part can be clamped quickly, thereby improving the stretching detection efficiency of the device.

[0044] In summary, the metal stretching detection device of the embodiment of the utility model can quickly clamp metal parts, thereby improving the stretching detection efficiency of the device.
