Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a boring machine. Background Art

[0002] A boring machine is a machine tool used to process high-precision holes or complete the finishing of multiple holes in one positioning. Its main working principle is to use the cutting edge to cut the workpiece, and the workpiece is processed into the required size and shape through the rotation and feed motion of the boring cutter. The boring machine has high processing accuracy and can meet some high-precision processing needs. The spindle radial runout is an important indicator used to evaluate the stability and accuracy of the spindle in the field of mechanical manufacturing. It refers to the radial offset generated by the spindle during rotation, that is, the radial vibration generated by the working parts on the spindle. In a boring machine, the spindle radial runout is an important consideration. A boring machine is a machine tool used to process high-precision holes, and the spindle is the main component used for cutting and processing in a boring machine. The accuracy of the spindle radial runout directly affects the quality of the holes processed by the boring machine, including the diameter accuracy, roundness error and position accuracy of the hole. Therefore, in order to ensure the processing accuracy of the boring machine, it is necessary to regularly measure the spindle radial runout accurately.

[0003] Currently, the spindle radial runout of boring machine spindles is mostly measured using a micrometer. The operator touches the contact of the micrometer to the spindle surface, rotates the spindle one circle, observes the maximum and minimum values of the indicator pointer swing, and takes the difference between the two, which is the radial runout of the boring machine spindle. However, in actual use, a simple external bracket is usually used for the installation of the micrometer, which cannot ensure the radial distribution of the micrometer along the spindle. Errors are prone to occur during the measurement process, resulting in inaccurate measurement results. Utility Model Content

[0037] Based on the above-mentioned structural setting, the boring machine is composed of a boring machine body 100 and a detection mechanism 200, wherein the detection mechanism 200 is assembled on the workbench of the boring machine body 100 by bolts. Specifically, during operation, the operator controls the boring machine body 100 to lower its spindle to the lowest position allowed. Subsequently, the operator also assembles the mounting frame 210 on the workbench of the boring machine body 100, and installs the first adjusting rod 230 and the second adjusting rod 240 on the mounting frame 210 respectively. A measuring tool 220 and a laser ranging sensor 2540 can be assembled into a group through an assembly part 250. The operator assembles the two measuring tools 220 and the two laser ranging sensors 2540 in groups to form two components that can be respectively assembled on the first adjusting rod 230 and the second adjusting rod 240. The first adjusting rod 230 is erected in the vertical direction, and the operator can adjust the lifting and lowering of the component. Under the action of the laser ranging sensor 2540, the minimum distance is taken. The second adjusting rod 240 is arranged horizontally, and the operator can adjust the horizontal movement of another component. Under the action of the other laser ranging sensor 2540, the minimum distance value point is taken to position the laser ranging sensor 2540. At this time, the two measuring tools 220 are perpendicular to each other and are distributed along the radial direction of the main shaft, ensuring the accuracy of the spindle diameter runout measurement result of the boring machine body 100. The boring machine is provided with a detection mechanism 200, a first adjusting rod 230 distributed in the vertical direction and a second adjusting rod 240 arranged horizontally, and with the help of an assembly part 250, the two measuring tools 220 can be respectively arranged at a vertical angle on the outside of the main shaft of the boring machine body 100. At the same time, in conjunction with the laser ranging sensor 2540, the two measuring tools 220 can be adjusted to be distributed along the radial direction of the main shaft of the boring machine body 100 to ensure the accuracy of the spindle diameter runout measurement result of the boring machine body 100. It is easy to install and flexible to debug, which improves maintenance efficiency.

[0038] Furthermore, the mounting frame 210 includes a first slide 2110 and a second slide 2120. The first slide 2110 is arranged along a horizontal plane, and the second slide 2120 is vertically mounted on top of the first slide 2110. The first slide 2110 arranged along the horizontal plane provides structural support for the assembly of the first adjustment rod 230 and the second slide 2120, while the second slide 2120 provides structural support for the assembly of the second adjustment rod 240.

[0039] Furthermore, the measuring tool 220 is composed of a dial indicator 2210 and a dial indicator 2220. Since boring machines are high-precision machining equipment, the measuring tool 220 is often a dial indicator 2210. In actual use, the radial runout at the spindle root is generally less noticeable than at its front end. Preferably, the measuring tool 220 for measuring at the spindle root is generally a dial indicator 2220, which facilitates observation and reading by the operator. Furthermore, the two measuring tools 220 can be combined in various ways to meet specific usage requirements, such as two dial indicators 2210, two dial indicators 2220, or a front-mounted dial indicator 2210 and a rear-mounted dial indicator 2220, thereby enhancing flexibility.

[0040] Furthermore, a first slider 2310 is provided at the end of the first adjusting rod 230 and the second adjusting rod 240, a second slider 2121 is provided at the bottom of the second slide seat 2120, and an outward-extending exhibition panel 2320 is provided on both sides of the first slider 2310 and the second slider 2121, and a second locking screw 2330 is threaded through the exhibition panel 2320. Among them, the first adjusting rod 230 is slidably mounted in the first slide 2110 through the first slider 2310, and the adjustment of the first adjusting rod 230 along the main shaft axis position can be adjusted; the second adjusting rod 240 is slidably mounted in the second slide 2120 through the first slider 2310, and the height of the second adjusting rod 240 can be adjusted; and the second slide 2120 is slidably mounted in the first slide 2110 through the second slider 2121, and the installation position of the second slide 2120 on the first slide 2110 can be adjusted, and then the position of the measuring tool 220 installed on the second slide 2120 along the main shaft axis can be adjusted.

[0041] Furthermore, a retaining groove 2525 is formed on the side of the movable clamping block 2523 away from the fixed clamping block 2522 to accommodate the end of the screw rod 2521. The fixed clamping block 2522 is fixedly connected to the support plate 2510, while the movable clamping block 2523 is slidably mounted on the support plate 2510. Specifically, during the installation of the measuring tool 220, the operator places the measuring tool 220 between the fixed clamping block 2522 and the movable clamping block 2523 and then tightens the screw rod 2521 until the fixed clamping block 2522 and the movable clamping block 2523 securely clamp the measuring tool 220. The retaining groove 2525 provides space for the contact end of the screw rod 2521 and the movable clamping block 2523, ensuring that the screw rod 2521 is securely and firmly mounted on the support plate 2510, further enhancing the secure clamping of the measuring tool 220.

[0042] Furthermore, both sides of the first slide 2110 are provided with positioning holes 2111 and strip holes 2112 for its assembly. The first slide 2110 is distributed along a horizontal plane, and the length direction of the first slide 2110 needs to be aligned with the main axis of the boring machine body 100. Specifically, the two positioning holes 2111 can limit the direction of the first slide 2110, while the two strip holes 2112 are used to ensure that the first slide 2110 is securely and firmly assembled on the workbench of the boring machine body 100, allowing for flexible adjustment of the installation and fixing points of the first slide 2110.
