[0024] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, but cannot be construed as limiting the technical solution of the present invention.

[0025] The quick test fixture provided in this application is used to test whether the rotating rod in the forklift shift system is qualified. The applicant has not verified whether this quick test is applicable to other structural products.

[0026] like Figures 5 to 7As shown, it is a structural schematic diagram, a front view and a top view of the rotating rod in the forklift shifting system used for testing by the quick inspection fixture of the utility model. As introduced in the background technology, the rotating rod is currently prepared by casting and then machining.

[0027] like Figures 1 to 4 As shown, the present application provides a quick inspection tool for determining whether the size of a rotating rod casting is qualified or not, comprising a contour inspection tool template 2, a handle 3 and a bolt 4. The contour inspection tool template 2 is fixedly connected to the handle 3 by the bolt 4. In the technical solution of the present application, the contour inspection tool template is rectangular or square.

[0028] An L-shaped contour detection groove 21 and a V-shaped contour detection groove 22 are provided on the contour gauge template 2, wherein the L-shaped contour detection groove is used to detect whether the L-shaped contour 11 of the rotating rod 1 is within the limit error range, and the V-shaped contour detection groove is used to detect whether the V-shaped contour 12 of the rotating rod 1 is within the limit error range. As for the layout of the L-shaped contour detection groove and the V-shaped contour detection groove on the contour gauge template, this application does not make any requirements.

[0029] The working principle of the quick test fixture of this product is:

[0030] The rotating rod blank to be tested is first placed in the L-shaped contour detection groove 21, and those that can be placed are then placed in the V-shaped contour detection groove 22. If both can be placed, the rotating rod blank is determined to be qualified. If any one cannot be placed, it is determined to be unqualified. Of course, during the test, it can also be placed in the V-shaped contour detection groove 22 first, and then placed in the L-shaped contour detection groove 21, which will not affect the test results.

[0031] In the technical solution of the present application, by using the above-mentioned quick inspection fixture, it is possible to detect whether the rotating rod is qualified. However, the disposal of unqualified rotating rods is still impossible to achieve, because through the detection, there must be a certain rotating rod blank whose contour is smaller than the standard value, and there must be a certain rotating rod blank whose contour is larger than the standard value. Moreover, these rotating rod blanks cannot all be treated as waste, which will lead to increased costs and waste. In this case, the development of the above-mentioned quick inspection fixture becomes an inevitable need.

[0032] Another embodiment of the present application is an improved technology based on the above-mentioned quick inspection fixture. Specifically, lateral pressure sensors are provided in the L-shaped contour detection groove and the V-shaped contour detection groove. The lateral pressure sensors are electrically connected to the controller. The lateral pressure sensors and controllers of the present application are products that can be obtained through commercial channels.

[0033] The lateral pressure sensor is arranged on the side wall of the L-shaped contour detection groove and the V-shaped contour detection groove, wherein three lateral pressure sensors are arranged in the L-shaped contour detection groove, namely the first lateral pressure sensor, the second lateral pressure sensor and the third lateral pressure sensor, respectively, and a lateral pressure sensor is arranged in the V-shaped contour detection groove, namely the fourth lateral pressure sensor, and the above four pressure sensors are all connected to the controller by electrical signals. This is because, when the rotating rod blank is inspected, in the process of being placed in the above-mentioned L-shaped contour detection groove or V-shaped contour detection groove, if the size of the rotating rod meets the standard size, the rotating rod will have a standard range of lateral pressure on the side wall of the L-shaped contour detection groove or the V-shaped contour detection groove, if the size of the rotating rod is smaller than the standard size, the force of the rotating rod on the side wall of the L-shaped contour detection groove or the V-shaped contour detection groove will definitely be smaller than the standard range of lateral pressure, similarly, when the size of the rotating rod is larger than the standard size, the force of the rotating rod on the side wall of the L-shaped contour detection groove or the V-shaped contour detection groove will definitely be greater than the standard range of lateral pressure.

[0034] With regard to the layout of lateral pressure sensors in the L-shaped contour detection groove and the V-shaped contour detection groove, the first lateral pressure sensor and the second lateral pressure sensor are arranged at the side walls of the two straight sides of the L-shaped contour detection groove, the third lateral pressure sensor is arranged at the side wall of the corner of the L-shaped contour detection groove, and the fourth lateral pressure sensor is arranged at the side wall near the middle position of the V-shaped contour detection groove. In order to ensure the accuracy of the detection data, all lateral pressure sensors are arranged in the upper third of the contour detection groove in the depth direction, otherwise it will cause large errors in the detection data and affect the detection results.

[0035] The controller of the present application can be installed on a handle or a contour detection template, and also includes a display screen or an alarm device, both of which are electrically connected to the controller. The alarm device is used to send an alarm signal or an alarm sound when the rotating rod is detected to be unqualified. It also includes a printing device electrically connected to the controller for printing data codes.

[0036] The working principle is:

[0037] When the standard rotating rod is placed in the L-shaped contour detection groove and the V-shaped contour detection groove, the value range detected by each lateral pressure sensor is determined as the standard threshold value for subsequent rotating rod detection.

[0038] The rotating rod to be tested is first placed in an L-shaped contour detection groove or a V-shaped contour detection groove. The lateral pressure sensor in the corresponding contour detection groove transmits the detected pressure value to the controller. The controller compares the detected pressure value with the standard threshold value. If it is within the standard threshold value range, the rotating rod blank is determined to be qualified, otherwise it is unqualified.

[0039] It also includes that, when the detected pressure value is greater than the maximum value of the standard threshold, the controller generates a corresponding data code for the detected pressure value.

[0040] The controller sends the data code to the printing device, which prints out the data code and sticks it on the rotating rod. When machining these rotating rod blanks that exceed the standard range, the corresponding data of the rotating rod blank can be obtained by scanning the code through the scanning device installed on the machine, thereby adjusting the machining parameters of the machining equipment to finally obtain a qualified rotating rod.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
