[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] One embodiment of the present invention provides a special bracket for an automatic gauge block detection device. In the embodiment of the present invention, the automatic gauge block detection device includes a robotic arm, a probe and a workbench, and the special bracket for the automatic gauge block detection device includes three parts: a gauge block bracket, a bracket base and a base tray. The gauge block bracket is used to simultaneously install two gauge blocks, that is, a standard gauge block and a measured block. The bracket base is designed to facilitate the robotic arm to lift the gauge block bracket using a fork, and is used to place the gauge block bracket. The base tray is composed of a plurality of positioning bases for placing the gauge block brackets.

[0020] like Figure 1 As shown, the gauge block bracket is provided with: a first rectangular hole 102 for placing the block to be measured; a second rectangular hole 104 for placing the standard gauge block; a circular slot 101, which is provided at the end of the first rectangular hole 102, so that when the probe of the measuring instrument (gauge block automatic detection device) moves down to measure the corner point of the gauge block, it will not contact the gauge block bracket to avoid measurement errors; a side groove 103, which is provided on the side of the gauge block bracket, so that when it is necessary to move the gauge block position on the workbench of the measuring instrument, the robot arm can move the gauge block bracket by inserting the fork piece into the side groove 103, and drive the gauge block to move at the same time. This side groove 103 does not penetrate inward, so as to avoid the fork piece of the robot arm contacting the standard gauge block and the block to be measured in the gauge block bracket during the measurement process to cause measurement errors or gauge block wear; a limit groove 105, which is provided on the upper and lower sides of the gauge block bracket, is used to fix the position of the gauge block bracket when it is placed on the bracket base.

[0021] The gauge block bracket is made of non-metallic material, which is lower in hardness than the bearing steel used to make the gauge block. The gauge block bracket is composed of a variety of internal dimensions to accommodate gauge blocks of different sizes. A horizontal bar can also be installed at the bottom of the gauge block bracket to support a larger gauge block. The installed horizontal bar cannot affect the contact between the gauge block and the ribbed workbench.

[0022] like Figure 2As shown, the bracket base is provided with: a fixing screw hole 201 for inserting a fixing screw to fix the bracket base on the base tray; an insertion slot 202 for inserting the fork on the robot arm between the gauge block bracket and the bracket base; a limiting column 203 for fixing the position of the gauge block bracket when placing it.

[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 that a certain gap is left when the fork is inserted.

[0024] like Figure 3 As shown, the base tray 301 is used to place multiple bracket bases, each bracket base is placed in a fixed position, and the position coordinates of each bracket base can be input into the automatic gauge block detection device through software. During measurement, the robot arm can accurately and quickly move to the corresponding base position according to the position coordinates of each bracket base to fork the corresponding gauge block. Multiple bracket bases are arranged in a rectangular shape on the base tray with intervals between them.

[0025] When the robot arm starts working, it will automatically position itself Figure 3 The coordinate point of the gauge block bracket on the base. The robot arm inserts the fork piece from the insertion slot 202, and then lifts the fork piece to lift the gauge block bracket with the gauge block. It is placed on the workbench below the measuring instrument probe. The ribbed workbench is provided with a groove similar to the insertion slot 202. When it is lowered, the fork piece will drop into the groove of the ribbed workbench. At this time, the gauge block bracket will be supported on the ribbed workbench, and the gauge block will also contact the ribbed workbench, and there is no other external force affecting the contact between the gauge block and the workbench. When the gauge block bracket is placed, the fork piece will be moved out of the groove on the ribbed workbench and inserted into the side groove 103. When it is necessary to move the gauge block position on the workbench, the robot arm can move the gauge block bracket by inserting the fork piece into the side groove 103 to avoid inaccurate measurement caused by contact with the gauge block during the measurement process. After the measurement is completed, the fork piece of the robot arm withdraws from the side groove 103, inserts into the groove on the ribbed workbench to lift the gauge block bracket, and then puts the gauge block bracket back on the original bracket base. Repeat this process until all the gauge blocks in the base tray are measured.

[0026] To summarize, the special bracket for the automatic detection device of the gauge block in the embodiment of the present invention has the following beneficial effects: it adopts a row of double rectangular hole structures, and can simultaneously place and move standard gauge blocks and measured blocks; the bracket base placed on the base tray can input the corresponding gauge block nominal length coordinate points in the system in advance, and can quickly locate the gauge block of the corresponding nominal length for measurement; the gauge block bracket is made of non-metallic material and has side grooves on the side for the robot arm to insert, and the side grooves are not through, so that the robot arm does not contact the gauge block in the bracket when clamping the bracket, thereby avoiding wear of the gauge block; when clamping the gauge block, the robot arm fork provides support throughout the process, and a horizontal bar can be added to the bottom of the bracket to support a larger gauge block, which can protect the gauge block from falling throughout the process; during the measurement process, the robot arm fork is inserted into the side groove of the gauge block bracket, does not contact the gauge block to avoid affecting the measurement accuracy, and the data measurement of the center length and four corner points of the gauge block can be completed at one time by moving the gauge block bracket on the workbench by the robot arm.

[0027] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
