DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same technical meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0025] like Figure 1 As shown, a bolt stress detection device which is easy to adjust includes a driving mechanism 200 for cooperative transmission, and also includes a detection mechanism 100. The detection mechanism 100 includes a transmission member 110. One side of the transmission member 110 is transmission-connected to the driving mechanism 200. A detection member 120 is installed on the transmission member 110. A plurality of detection members 120 are equally divided. The plurality of detection members 120 are correspondingly arranged to the bolts and nuts. An auxiliary member 130 is arranged inside the transmission member 110. The auxiliary member 130 supports the bolts and nuts. Most nuts and bolts are hexagonal. When detecting larger nuts, it is more accurate to detect multiple sides at the same time.

[0026] The driving mechanism 200 is used to drive the transmission ring 112 to rotate. The driving mechanism 200 can be a motor with a gear, or a handle is provided on the gear. By rotating the handle, the gear is driven to engage with the transmission ring 112, so that the transmission ring 112 rotates.

[0027] like Figure 2 and Figure 3 As shown, the transmission member 110 includes a mounting plate 111 and a limiting cylinder 114. The mounting plate 111 is provided with a transmission ring 112 for limiting rotation. Grooves 117 are evenly spaced on the transmission ring 112. A mounting shell 115 is provided in the groove 117 for limiting sliding. The limiting cylinder 114 is fixedly installed on one side of the transmission ring 112. The grooves 117 on the transmission ring 112 are tilted, and there are 6 grooves 117 equally spaced around. The transmission ring 112 is driven by the driving mechanism 200 to drive the mounting shell 115 to limit sliding in the groove 117 of the transmission ring 112. At the same time, the tilted setting facilitates the displacement distance of the mounting shell 115.

[0028] The bottom of the mounting shell 115 is fixedly connected with a limited connecting rod 116, and the limited connecting rod 116 slides in a corresponding limited position in the groove 117 of the transmission ring 112. The bottom of the transmission ring 112 is fixedly installed with a ring rail 113, and the surface of the mounting plate 111 is provided with a slide groove 118 matching the ring rail 113, and the outer wall of the transmission ring 112 is provided with teeth, which facilitate the rotation of the transmission ring 112.

[0029] like Figure 2 and Figure 4 As shown, the detection member 120 includes a mounting rod 121 and a detection shell 124, a magnetic memory sensor is installed inside the detection shell 124, one end of the mounting rod 121 is connected and installed on one side of the mounting shell 115, the other end of the mounting rod 121 is limitedly connected with an extension rod 122, the extension rod 122 is limitedly rotatably connected to the detection shell 124, the mounting rod 121 is limitedly slidable through the limit cylinder 114, the interior of the mounting shell 115 is used to place a battery circuit board, etc., a connecting line is arranged inside the extension rod 122 to be connected to the magnetic memory sensor, and the magnetic memory sensor is located at the end of the detection shell 124 for detecting bolts.

[0030] The interior of the extension rod 122 is hollow, and the interior of the mounting rod 121 is hollow, and the extension rod 122 is connected to the internal thread of the mounting rod 121. The end of the extension rod 122 close to the detection shell 124 is fixedly sleeved with a limit ring 123, and the end of the detection shell 124 is provided with a slide groove that matches the limit ring 123. The extension rod 122 cooperates with the limit ring 123 to be rotationally connected with the detection shell 124, and the detection shell 124 will not rotate when the length of the extension rod 122 is adjusted.

[0031] See also Figure 2 and Figure 4The auxiliary member 130 includes an upper support plate 131 and a lower mounting plate 132. The lower mounting plate 132 is fixedly mounted on the middle of the mounting plate 111. The upper support plate 131 is fixed to the lower mounting plate 132 by a spring. The middle of the upper support plate 131 and the lower mounting plate 132 is hollow. The center thread of the mounting plate 111 is connected with a limit rod 133. The limit rod 133 is used to roughly limit the position of the nut so that the nut is located in the middle of the mounting plate 111. The upper support plate 131 and the lower mounting plate 132 are used to support the nut. At the same time, when the bolt is tested, the bolt head is placed on the upper support plate 131 for testing.

[0032] Working principle: When testing the nut, the nut is sleeved on the limit rod 133, and the transmission ring 112 is driven to rotate through the driving mechanism 200. The transmission ring 112 transmits the limit connecting rod 116 through the inclined groove 117 to make the mounting shell 115 slide in the inclined groove 117, so that the mounting rod 121 drives the detection shell 124 to penetrate into the interior of the limit cylinder 114, and the six sides of the nut are squeezed and tested at the same time. If the size of the nut is small or large, the length of the extension rod 122 and the mounting rod 121 is adjusted by rotating the extension rod 122, so that the detection shell 124 is close to the nut. If the bolt is tested, the limit rod 133 is disassembled, the bottom of the bolt is threadedly connected to the mounting plate 111, and the bolt head is placed on the upper support plate 131. At the same time, the transmission ring 112 drives the detection shell 124 to approach for testing. Multi-directional simultaneous detection is more accurate when testing larger bolts.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that, for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
