Therefore, an automatic gauge block measurement device is urgently needed to improve the detection efficiency and release manpower. However, automatic measurement of gauge blocks requires the use of mechanical arms to clamp and accurately move the gauge blocks, so a new special support completely suitable for automatic measurement must be developed to solve the related problems.

[0018] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0019] An embodiment of the present application provides a special support for a gauge block automatic detection device. In the embodiment of the present application, the gauge block automatic detection device comprises a mechanical arm, a measuring head and a workbench, and the special support for the gauge block automatic detection device comprises three parts, namely, a gauge block support, a support base and a base tray. The gauge block support is used to simultaneously mount two gauge blocks, namely, a standard gauge block and a measured gauge block. The support base is designed to facilitate the mechanical arm to lift the gauge block support by using a fork and is used to place the gauge block support. The base tray is composed of a plurality of positioning bases for placing the gauge block support.

[0020] As shown in Figure 1 , the gauge block support is provided with: a first rectangular hole 102 for placing the measured gauge block; a second rectangular hole 104 for placing the standard gauge block; a circular groove 101 provided at the end of the first rectangular hole 102, which is used to avoid contacting the gauge block support when the measuring head of the measuring instrument (gauge block automatic detection device) is lowered to measure the corner point of the gauge block, so as to avoid measurement error; a side groove 103 provided on the side of the gauge block support, which is used to move the position of the gauge block on the workbench of the measuring instrument by inserting the fork of the mechanical arm into the side groove 103 to move the gauge block support and simultaneously drive the gauge block to move. The side groove 103 does not penetrate inward, so as to avoid the fork of the mechanical arm contacting the standard gauge block and the measured gauge block in the gauge block support during the measurement process, which causes measurement error or gauge block wear; and limiting grooves 105 provided on the upper and lower sides of the gauge block support, which are used to fix the position of the gauge block support when the gauge block support is placed on the support base.

[0021] The gauge block support is made of non-metallic material with a hardness lower than the bearing steel used to manufacture the gauge block. The gauge block support is composed of a plurality of inner sizes to adapt to the sizes of different gauge blocks. The bottom of the gauge block support can also be additionally provided with a cross strip to support a larger gauge block, and the additionally provided cross strip cannot affect the contact between the gauge block and the ribbed workbench.

[0022] As shown in Figure 2As shown, the support base is provided with: fixed screw hole 201, for inserting a fixed screw, fixing the support base on the base tray; insertion slot 202, for the fork on the mechanical arm to insert between the gauge block support and the support base; limiting column 203, for placing the gauge block support to fix its position.

[0023] The support base is made of the same non-metallic material as the gauge block support. The depth of the insertion slot 202 ensures a certain gap when the fork is inserted.

[0024] As shown, Figure 3 The base tray 301 is used to place a plurality of support bases, and the placement position of each support base is fixed. The position coordinates of each support base can be input into the gauge block automatic detection device through software. During measurement, the mechanical arm can move to the corresponding base position according to the position coordinates of each support base to pick up the corresponding gauge block. The plurality of support bases are arranged in a rectangular shape on the base tray, and are spaced apart from each other.

[0025] When the mechanical arm starts working, it will automatically locate the coordinate point of the gauge block support placed on the base. Figure 3 The fork is inserted into the insertion slot 202, and then the fork is lifted to lift the gauge block support with the gauge block. The gauge block support is placed on the workbench below the measuring instrument probe. The ribbed workbench is provided with a slot similar to the insertion slot 202. When the fork is lowered into the slot of the ribbed workbench, the gauge block support will be supported on the ribbed workbench, and the gauge block will also contact the ribbed workbench without other external forces affecting the contact between the gauge block and the workbench. When the gauge block support is placed, the fork is removed from the slot on the ribbed workbench and inserted into the side recess 103. When the gauge block position needs to be moved on the workbench, the mechanical arm can move the gauge block support by inserting the fork into the side recess 103, avoiding contact with the gauge block during measurement to cause inaccurate measurement. After completing the measurement, the fork of the mechanical arm is withdrawn from the side recess 103 and inserted into the slot on the ribbed workbench to lift the gauge block support, and then the gauge block support is placed back on the original support base. Repeat this process until all the gauge blocks on the base tray are measured.

[0026] In summary, the gauge block automatic detection device special support has the following beneficial effects: the double-row double rectangular hole structure can place and move the standard gauge block and the measured gauge block at the same time; the support base placed on the base tray can input the corresponding gauge block nominal length coordinate point in advance, and the gauge block of the corresponding nominal length can be quickly positioned and measured; the gauge block support is made of non-metallic material and has a side groove for the mechanical arm to insert, the side groove is not through, so that the mechanical arm does not contact the gauge block in the support when clamping the support, thereby avoiding the wear of the gauge block; the mechanical arm fork provides support throughout when clamping the gauge block, the bottom of the support can be additionally provided with a horizontal bar for supporting a large amount of gauge blocks, and the gauge block can be protected from falling throughout; in the measurement process, the mechanical arm fork is inserted into the side groove of the gauge block support without contacting the gauge block to avoid affecting the measurement accuracy, and the data measurement of the center length and the four corner points of the gauge block can be completed at one time by moving the gauge block support on the workbench through the mechanical arm.

[0027] The foregoing merely describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the foregoing drawings and descriptions are illustrative in nature, and should not be construed as limiting the scope of the claims of the present application.
