Abstract
Description
Technical Field
[0001] This utility model belongs to the field of workpiece measurement technology, and in particular relates to an online outer diameter measuring device. Background Technology
[0002] Workpiece measurement is the process of measuring the data performance of a workpiece using machine tool hardware and corresponding measuring tools. It is widely used in the field of machining and is a key link in ensuring the dimensional accuracy and machining quality of workpieces. By measuring the outer diameter of the workpiece, a preliminary judgment can be made as to whether the workpiece machining operation has met the required standards. Workpiece measurement is an indispensable part of machining. By selecting appropriate measurement methods, developing detailed measurement plans, preparing sufficient measuring tools, and strictly following the measurement procedures, accurate measurement of workpiece dimensional accuracy can be achieved, thereby improving the quality and efficiency of machining.
[0003] Currently, when measuring the outer diameter of finished workpieces in factories, it is mostly done manually using measuring tools such as vernier calipers. This requires manually adjusting the vernier caliper scale and placing the vernier caliper at different points on the outside of the workpiece for measurement. The adjustment process of the vernier caliper is a very tedious procedure, which makes the manual measurement of the outer diameter of workpieces inefficient and difficult to measure the outer diameter of a large number of workpieces in a short time, thus affecting production efficiency. Therefore, it is necessary to provide an online outer diameter measuring device to solve the above problems. Utility Model Content
[0004] The technical content of this utility model is to provide an online outer diameter measuring device.
[0005] To address the aforementioned problems, this utility model provides an online outer diameter measuring device, including an operating table. A mounting rail is installed on the top of the operating table, and limit blocks are installed on the side of the mounting rail. Two sets of first measuring brackets are symmetrically installed on the top of the mounting rail. A second measuring bracket is installed on the left side of the right set of first measuring brackets. A guide rail is installed at the bottom of the second measuring bracket, and the guide rail is mounted on the top of the mounting rail. A measuring pen is installed on the left side of the second measuring bracket. Two sets of springs are symmetrically installed on the bottom right side of the left set of first measuring brackets, with the other end of each spring connected to the bottom left side of the second measuring bracket. Two sets of material support racks are installed on the top of the operating table, and the workpiece to be measured is placed on the top of each material support rack.
[0006] As a further solution of this utility model, the operating table is provided with three sets of mounting holes, the mounting rail is located on the top left side of the operating table, and the bottom of the left set of first measuring brackets installed on the mounting rail is fixedly connected to the top of the mounting rail, and the bottom of the right set of first measuring brackets is fixedly connected to the limiting block. The limiting block is fixedly connected to the mounting rail, thereby fixing the two sets of first measuring brackets on the top of the mounting rail.
[0007] As a further solution of this utility model, the guide rail is fixedly installed at the top center of the mounting rail, the length of the guide rail is less than the length of the mounting rail, the guide rail is configured as an I-shaped structure, and the bottom of the second measuring bracket is provided with a sliding groove that matches the guide rail, so that the second measuring bracket can slide on the top of the guide rail.
[0008] As a further solution of this utility model, the two sets of material support frames are installed on both sides of the mounting rail. The set of material support frames on the left side is closer to the mounting rail than the set of material support frames on the right side. The material support frames are provided with grooves that are adapted to the shape of the workpiece to be measured. When the outer diameter of the workpiece to be measured is detected, it is placed in the grooves at the top of the two sets of material support frames. The workpiece to be measured is located between the first measuring bracket and the second measuring bracket on the right side.
[0009] As a further solution of this utility model, a through hole is provided at the upper end of the first measuring bracket on the left side, through which the measuring pen passes. The right end of the measuring pen contacts the upper left end of the second measuring bracket. Two sets of springs connect the first measuring bracket on the left side and the second measuring bracket. Under the action of the two sets of springs, a fixed distance is maintained between the second measuring bracket and the first measuring bracket on the right side. After the workpiece to be measured is removed, the spring drives the second measuring bracket to move to the right along the guide rail to reset, so as to continuously detect multiple workpieces to be measured.
[0010] Compared with related technologies, the online outer diameter measuring device provided by this utility model has the following beneficial effects:
[0011] 1. This utility model involves installing two sets of first measuring brackets on an installation rail. A second measuring bracket is installed on the left side of the first measuring bracket on the right side. The second measuring bracket is located on the top of the guide rail at the top of the installation rail. The second measuring bracket can move along the guide rail, thereby driving the measuring pen installed on the left side of the second measuring bracket to move along the through hole opened between the first measuring bracket on the left side. During measurement, the workpiece to be measured only needs to be placed between the first measuring bracket on the right side and the second measuring bracket. At this time, relative movement occurs between the measuring pen and the first measuring bracket on the left side. By observing the scale on the measuring pen, it can be determined whether the outer diameter of the workpiece meets the standard. This method is much more convenient than the measurement method of manual vernier calipers.
[0012] 2. This utility model symmetrically installs two sets of springs at the bottom right side between a set of first measuring brackets on the left side. The right end of the springs is connected to the bottom left side of the second measuring bracket. Under the action of the springs, a fixed distance is maintained between the second measuring bracket and the set of first measuring brackets on the right side. When measuring the outer diameter of the workpiece to be measured, the second measuring bracket moves to the left. At this time, the spring is in a compressed state. After the measurement is completed, the workpiece to be measured is removed, and the spring can drive the second measuring bracket to move to the right along the guide rail to reset, so as to continuously detect multiple workpieces to be measured.

[0017] Please refer to the following: Figure 1-2 An online outer diameter measuring device includes an operating table 1, an mounting rail 2 mounted on the top of the operating table 1, limit blocks 3 mounted on the side of the mounting rail 2, two sets of first measuring brackets 4 symmetrically mounted on the top of the mounting rail 2, a second measuring bracket 5 mounted on the left side of the right set of first measuring brackets 4, a guide rail 6 mounted on the bottom of the second measuring bracket 5, the guide rail 6 being mounted on the top of the mounting rail 2, a measuring pen 7 mounted on the left side of the second measuring bracket 5, two sets of springs 8 symmetrically mounted on the bottom right side of the left set of first measuring brackets 4, the other end of the springs 8 being connected to the bottom left side of the second measuring bracket 5, and two sets of material support racks 9 mounted on the top of the operating table 1, with the workpiece 10 to be measured placed on the top of the material support racks 9.
[0018] Preferably, the operating table 1 has three sets of mounting holes to fix the entire device on the mechanical device. The mounting rail 2 is located on the top left side of the operating table 1. The bottom of the left set of first measuring brackets 4 is fixedly connected to the top of the mounting rail 2, and the bottom of the right set of first measuring brackets 4 is fixedly connected to the limiting block 3. The limiting block 3 is fixedly connected to the mounting rail 2, thereby fixing the two sets of first measuring brackets 4 on the top of the mounting rail 2.
[0019] Preferably, the guide rail 6 is fixedly installed at the top center of the mounting rail 2. The length of the guide rail 6 is less than the length of the mounting rail 2. The guide rail 6 is set as an I-shaped structure. The bottom of the second measuring bracket 5 is provided with a sliding groove that matches the guide rail 6. The second measuring bracket 5 can slide on the top of the guide rail 6, and the second measuring bracket 5 cannot move upward, thereby ensuring the stability of the second measuring bracket 5 during operation.
[0020] Preferably, the two sets of material support frames 9 are installed on both sides of the mounting rail 2. The set of material support frames 9 on the left side is closer to the mounting rail 2 than the set of material support frames 9 on the right side. The material support frames 9 are provided with grooves that are adapted to the shape of the workpiece 10 to be measured. When the outer diameter of the workpiece 10 is measured, it is placed in the grooves at the top of the two sets of material support frames 9. The workpiece 10 to be measured is located between the first measuring bracket 4 and the second measuring bracket 5 on the right side.
[0021] Preferably, the upper end of the first measuring bracket 4 on the left side has a through hole, through which the measuring pen 7 passes.

The measuring pen 7 can move along the through hole on the first measuring bracket 4 on the left side. Two sets of springs 8 connect the first measuring bracket 4 on the left side and the second measuring bracket 5. Under the action of the two sets of springs 8, a fixed distance is maintained between the second measuring bracket 5 and the first measuring bracket 4 on the right side. When it is necessary to inspect the workpiece 10, the workpiece 10 is placed... Between the first measuring bracket 4 and the second measuring bracket 5 on the right, the second measuring bracket 5 moves to the left along the guide rail 6, causing the measuring pen 7 to move to the left along the through hole at the upper end of the first measuring bracket 4 on the left. By observing the scale on the measuring pen 7, it can be determined whether the workpiece 10 to be tested is qualified. When the workpiece 10 to be tested is inspected, the spring 8 is in a compressed state. After the workpiece 10 to be tested is removed, the spring 8 drives the second measuring bracket 5 to move to the right along the guide rail 6 to reset, so as to continuously test multiple workpieces 10 to be tested.
