Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, specifically a multi-section diameter measuring device. Background Technology

[0002] A workpiece refers to the object being machined during the machining process. It can be a single part or a combination of several parts fixed together. When machining a workpiece, it is usually necessary to open an inner hole in the workpiece. In order to ensure the accuracy of the inner hole when it is used, it is necessary to measure the inner hole of the machined workpiece, which requires the use of a multi-section diameter measuring device.

[0003] The existing technology has the following problems: When measuring a workpiece, the measuring rod is usually heavy, making it difficult for operators to push it horizontally for measurement. A balancer is usually used to lift the measuring rod to solve the weight problem. This makes it inconvenient to quickly measure the inner hole of the workpiece, as well as to position and fix the workpiece, and to measure multiple inner holes of the workpiece at the same time.

Figure 1-6 As shown, the device includes a base 1, a fixed seat 4 is fixedly installed on the top of the base 1, a workpiece body 5 is fixedly connected to the top of the fixed seat 4, and two floating structure devices 6 are slidably connected to the top of the base 1. The two floating structure devices 6 are located on one side of the fixed seat 4 and are arranged in a front-back position. A first measuring rod 8 and a second measuring rod 9 are fixedly connected to one side of the two floating structure devices 6 respectively. The first measuring rod 8 and the second measuring rod 9 are both corresponding to the workpiece body 5. Multiple measuring holes 10 are provided around the periphery of the first measuring rod 8 and the second measuring rod 9. Multiple support columns 2 are fixedly installed at the bottom of the base 1. The multiple support columns 2 are cylindrical in shape of the same size and are positioned in the front and back correspondingly. Two handles 3 are fixedly installed on the front and rear sides of the base 1, and handrails 7 are fixedly connected to the top of the two floating structure devices 6.

The multiple measuring holes 10 around the first measuring rod 8 and the second measuring rod 9 can be used to simultaneously measure multiple inner holes in the workpiece body 5, making the detection operation faster and more accurate. By pulling the two floating structure devices 6 to the right, the first measuring rod 8 and the second measuring rod 9 can be moved to the right synchronously, so that the first measuring rod 8 and the second measuring rod 9 are separated from the workpiece body 5, making it easy to disassemble and remove the workpiece body 5. This allows for convenient and quick positioning, fixing and disassembly of the workpiece. The guide sleeve 13 can guide the second measuring rod 9 and the workpiece body 5, making it easier for the second measuring rod 9 to be inserted into the inside of the workpiece body 5 and avoiding the second measuring rod 9 from scratching the workpiece. When the floating structure device 6 moves left and right, it can drive the sliding seat 12 to slide left and right along the sliding rod 11.
