Abstract
Description
Technical Field
[0001] This application relates to the field of boring machines, and in particular to a tooling for installing and verifying the boring bar of a boring machine. Background Technology
[0002] In the field of machining, boring is an important process widely used in various hole machining operations, playing a crucial role in ensuring the dimensional accuracy, shape accuracy, and surface quality of workpiece holes. During boring, the W-axis boring bar, as the core component performing the machining actions, has a decisive impact on machining accuracy and efficiency due to the stability and accuracy of its motion. If the movement of the W-axis boring bar deviates due to large errors in the generatrix of the lead screw drive module or guide rod, it will directly lead to out-of-tolerance dimensions and irregular shapes in the machined holes, severely affecting the overall quality of the workpiece. Simultaneously, unstable motion will reduce machining efficiency, increase tool wear, and raise production costs.
[0003] Currently, during the assembly and debugging of the boring bar and spindle box, the accuracy verification between the W-axis boring bar and the lead screw or guide rod mainly relies on dial indicators. While dial indicators, as a traditional measuring tool, can meet basic measurement needs to a certain extent, the circular structure of the boring bar itself presents several limitations during measurement. Specifically, when using a dial indicator to measure the W-axis drive lead screw and guide rod, it is difficult to mount the dial indicator on the W-axis boring bar. Factors such as the selection of the measurement point, the control of the measuring force, and the slight vibrations of the boring bar itself can easily introduce measurement deviations.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] (II) Technical Solution
[0008] To solve the above-mentioned technical problems, this application provides the following technical solution:
[0009] A fixture for installing and verifying a boring bar on a boring machine is provided, used to install a testing device. The testing device is used to test the generatrix of the lead screw or guide rod of the boring bar. The fixture for installing and verifying the boring bar on a boring machine includes:
[0010] The tooling body has a through hole inside and a positioning key inside the through hole. The tooling body has a mounting surface on the outside, which can be a horizontal or vertical surface.
[0011] The boring bar has a positioning groove on its outer side that matches the positioning key, and the positioning groove extends parallel to the axis of the boring bar. When the detection device detects the generatrix of the lead screw or guide rod of the boring bar, the tooling body is movably sleeved on the outer side of the boring bar through a through hole, the positioning key is movably disposed in the positioning groove, and the mounting surface is used to install the detection device so that the detection device is oriented towards the lead screw or guide rod.
[0012] In some embodiments, the tooling body includes an upper body and a lower body that are detachably connected to each other. The upper body and the lower body are each provided with an arc-shaped hole, and the arc-shaped holes of the upper body and the lower body surround each other to form the through hole. An installation groove is provided on the inner side of the arc-shaped hole, and the positioning key is fixedly installed on the inner side of the installation groove by bolts.
[0013] In some embodiments, the upper body and the lower body are magnetically attached and magnetically connected to each other; or the upper body and the lower body are connected by bolts.
[0014] In some embodiments, the tooling body has a cubic structure in its outer contour, and the top, side, or bottom surface of the tooling body is configured as the mounting surface.
[0015] In some embodiments, the boring machine includes a spindle box, a tailstock, a drive spindle, a boring bar, a push-pull seat, a guide rod, and a lead screw drive module; the drive spindle is disposed inside the spindle box and is drively connected to the boring bar; the tailstock is fixedly disposed in the spindle box; the push-pull seat is axially movable and sleeved on the outside of the boring bar, and is fixedly disposed with a nut and a guide sleeve; the guide rod is fixedly disposed in the tailstock and is slidably connected to the guide sleeve; the lead screw drive module includes a lead screw rotatably disposed in the tailstock, and the lead screw is threadedly connected to the nut; the tooling body is detachably disposed on the boring bar.
[0016] In some embodiments, the rear trunk is provided with two spaced-apart support seats, each support seat having a horizontally extending mounting hole and a locking hole communicating with the mounting hole; each end of the guide rod is provided with one of the mounting holes, and a locking bolt is provided in the locking hole for fixing the guide rod in the mounting hole.
[0017] In some embodiments, the push-pull seat is fixedly provided with a cutting tool cylinder, which is coaxially arranged with the boring bar.
[0018] (III) Beneficial Effects
[0019] Compared with the prior art, the beneficial effects of the technical solution provided in this application include at least the following:
[0020] The boring bar installation and calibration fixture of this application uses the boring bar as a reference to detect the generatrix of the guide rod and lead screw during operation. Specifically, when detecting the generatrix of the boring bar drive lead screw or guide rod, the fixture body is sleeved on the outside of the boring bar through an internal through hole, and engages with the positioning key on the inner side of the fixture through a pre-set axial positioning groove on the boring bar, forming a constraint relationship that only allows axial sliding. At this time, the detection device (such as a sensor or measuring instrument) is fixed on the horizontal or vertical mounting surface of the fixture body and precisely aligned with the lead screw or guide rod to be measured. When the fixture body slides along the axial direction of the boring bar, the positioning key guides synchronously within the positioning groove, ensuring that the detection device always stably points to the generatrix of the lead screw or guide rod, thereby continuously measuring its straightness or positional error. The positioning key, in cooperation with the positioning groove of the boring bar, reduces fixture offset and is more convenient to install compared to the traditional method of directly fixing measuring tools to a circular boring bar. Meanwhile, the mounting surface of the fixture body provides a horizontal or vertical rigid reference surface for the testing device, avoiding random errors caused by manually selecting measurement points and controlling measurement forces. The fixture body is a sleeve-type structure, fitted onto the outside of the boring bar, which can effectively suppress the transmission of minor vibrations of the boring bar, ensuring that the testing device maintains stable orientation during movement, directly obtaining the geometric accuracy of the lead screw / guide rod generatrix, thereby reducing measurement deviation.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0030] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.
[0031] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0032] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.
[0033] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0034] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values that would be recognized by one of ordinary skill in the art.
[0035] Existing methods for installing and verifying boring bars on boring machines have drawbacks, such as inconvenience in installing testing devices and a tendency to introduce measurement deviations.
[0036] To solve the above-mentioned technical problems, this embodiment provides a tooling for installing and verifying the boring bar of a boring machine.
[0037] Figure 1 This is a top view of the tooling for installing and verifying the boring bar of the boring machine and the boring machine in the embodiments of this application. Figure 2 yes Figure 1 sectional perspective view of section A. Figure 3 The tooling for installing and verifying the boring bar on the boring machine in the embodiments of this application and the boring bar are... Figure 1 Sectional view of section B in the middle. Figure 4 The tooling for installing and verifying the boring bar on the boring machine in the embodiments of this application and the boring bar are... Figure 1 Sectional view of section C.
[0038] See Figures 1 to 4 As shown, the tooling 1 for mounting and verifying the boring bar of the boring machine in this embodiment is mainly used to install a testing device to test the transmission lead screw or the busbar of the guide rod 26 of the boring bar 24.
[0039] like Figure 3 and 4 As shown, the tooling 1 for installing and verifying the boring bar of a boring machine includes a tooling body 11, which includes an upper body 111 and a lower body 112 that are detachably connected to each other. The upper body 111 and the lower body 112 are each provided with an arc hole 12. When the upper body 111 and the lower body 112 are connected, the arc holes 12 of the upper body 111 and the lower body 112 surround each other to form an internal through hole 13, which is used to fit on the outside of the boring bar 24.
[0040] Specifically, the upper body 111 and the lower body 112 can be connected in two ways. One way is that the upper body 111 and the lower body 112 are magnetically attached and connected to each other magnetically. This connection method is relatively convenient and quick to install and disassemble. The other way is that the upper body 111 and the lower body 112 are connected by bolts. The connection is firm and reliable and is suitable for testing scenarios with high stability requirements.
[0041] like Figure 3 and 4 As shown, an installation groove 121 is provided on the inner side of the arc hole 12, and the positioning key 14 is fixedly installed on the inner side of the installation groove 121 by bolts. The function of the positioning key 14 is to fit with the positioning groove 241 provided on the outer side of the boring bar 24. The extension direction of the positioning groove 241 is parallel to the axis of the boring bar 24 to ensure the stability of the tooling body 11 when it moves on the boring bar 24.
[0042] like Figure 2 and 3 As shown, the outer contour of the tooling body 11 is a cubic structure, and its top, side or bottom surface is configured as a mounting surface 15. The mounting surface 15 is a horizontal or vertical surface, used to fix and install the detection device, so that the detection device is set facing the transmission screw or guide rod 26, so as to perform busbar detection.
[0043] like Figure 1 and 2As shown, the tooling 1 is applied to a boring machine 2 system including a spindle box 21, a rear tail box 22, a drive spindle 23, a boring bar 24, a push-pull seat 25, a guide rod 26, and a lead screw drive module 27. The drive spindle 23 is housed within the spindle box 21 and is drive-connected to the boring bar 24. The rear tail box 22 is fixedly mounted on the spindle box 21. The push-pull seat 25 is axially movable and sleeved on the outside of the boring bar 24, and is fixedly fitted with a nut 251 and a guide sleeve 252. The guide rod 26 is fixedly mounted on the rear tail box 22 and is slidably connected to the guide sleeve 252. The lead screw drive module 27 includes a lead screw 271 rotatably mounted on the rear tail box 22, and the lead screw 271 is threadedly connected to the nut 251.
[0044] like Figure 2 As shown, the rear trunk 22 is provided with two spaced-apart support seats 28. Each support seat 28 has a horizontally extending mounting hole 281 and a locking hole 282 communicating with the mounting hole 281. Each end of the guide rod 26 is provided with a mounting hole 281, and a locking bolt is provided in the locking hole 282. By tightening the locking bolt, the guide rod 26 in the mounting hole 281 can be fixed, ensuring the stable installation of the guide rod 26 on the rear trunk 22.
[0045] like Figure 2 As shown, the push-pull seat 25 is fixedly equipped with a tool-removing cylinder 29. The tool-removing cylinder 29 is coaxially arranged with the boring bar. The tool-removing cylinder 29 can be used to realize operations such as tool loading and unloading. The coaxial arrangement with the boring bar can ensure accurate and stable force transmission.
[0046] In this boring machine system 2, all components work together to complete the boring machining task. The working process is as follows:
[0047] When the boring machine 2 starts working, the power source (such as a motor) starts, transmitting power to the drive spindle 23 inside the spindle box 21. The drive spindle 23, as a key component for power transmission, converts and transmits rotational power, providing the basic power for subsequent machining operations. Since the drive spindle 23 is connected to the boring bar 24, the rotation of the drive spindle 23 drives the boring bar 24 to rotate as well. The boring bar 24 is the core component that directly performs machining operations; its rotation is a prerequisite for boring. Through the rotation of the boring bar 24, the tool can cut the workpiece. When the boring bar 24 needs to perform axial feed motion (i.e., move along the axis of the boring bar 24) to complete machining at different depths, the lead screw drive module 27 starts working. The rotatable lead screw 271, located in the rear tailstock 22, begins to rotate under power drive (which can be driven by a motor or other drive device). Because the lead screw 271 is threadedly connected to the nut 251 fixed on the push-pull seat 25, according to the principle of threaded transmission, when the lead screw 271 rotates, the nut 251 will move along the axial direction of the lead screw 271. Since the nut 251 is fixed on the push-pull seat 25, the movement of the nut 251 will drive the push-pull seat 25 to move together along the axial direction of the boring bar 24. The push-pull seat 25 is axially movable and sleeved on the outside of the boring bar 24. This design ensures that the push-pull seat 25 can slide smoothly on the boring bar 24. During the movement of the push-pull seat 25, the guide rod 26 fixed on the rear tail box 22 plays an important role. The guide rod 26 is slidably connected to the guide sleeve 252 fixed on the push-pull seat 25. The guide sleeve 252 slides along the guide rod 26, providing precise guidance for the axial movement of the push-pull seat 25. The cooperation between the guide rod 26 and the guide sleeve 252 restricts the degree of freedom of the push-pull seat 25 during movement, preventing it from shifting or wobbling, thus ensuring the accuracy and stability of the axial feed motion of the boring bar 24. Through the aforementioned power transmission and axial feed stages, the boring bar 24 achieves both rotational motion and axial feed motion according to preset requirements. The synergistic effect of these two motions enables the tool mounted on the boring bar 24 to perform precise boring machining on the workpiece. During the machining process, according to the preset machining parameters (such as rotational speed, feed rate, and depth of machining), the boring bar 24 continuously performs rotational and axial feed motions, and the tool gradually cuts the workpiece until the required hole dimensional accuracy, shape accuracy, and surface quality requirements are achieved, completing the entire machining task.
[0048] The installation process of the above-mentioned boring bar installation and verification fixture 1 is as follows: Separate the upper body 111 and the lower body 112, and fit the fixture body 11 onto the outside of the boring bar 24, so that the positioning key 14 is aligned with the positioning groove 241 on the outside of the boring bar 24. Then, fix the upper body 111 and the lower body 112 together by magnetic attraction or bolt connection. At this time, the positioning key 14 is movably set in the positioning groove 241 to ensure that the relative position of the fixture body 11 and the boring bar 24 is stable and can move along the axial direction of the boring bar 24. Subsequently, according to the testing requirements, select a suitable mounting surface 15 (top surface, side surface or bottom surface), fix the testing device on the mounting surface 15, and adjust the direction of the testing device so that it faces the transmission screw or guide rod 26 in order to accurately test the busbar. Next, the main body 11 of the tooling is moved along the axial direction of the boring bar 24. During the movement, the testing device inspects the generatrix of the lead screw or guide rod 26, records relevant data, and analyzes the data to determine whether the accuracy of the generatrix meets the requirements. Finally, after the inspection is completed, the testing device is disassembled in the reverse order of installation. Then, the upper body 111 and the lower body 112 are separated, and the main body 11 of the tooling is removed from the boring bar 24, completing the entire inspection process.
[0049] In summary, the boring bar installation and calibration fixture 1 of this embodiment addresses the problem of difficult installation of measuring tools. It features a through hole 13 inside the fixture body 11, allowing the fixture body 11 to be movably fitted onto the outside of the boring bar 24 via this through hole 13. Simultaneously, the outer side of the boring bar 24 has a positioning groove 241 adapted to the positioning key 14 inside the through hole 13 of the fixture body 11. The positioning key 14 is movably positioned within the positioning groove 241. Furthermore, the outer side of the fixture body 11 has a mounting surface 15, on which the detection device is fixedly mounted and oriented towards the transmission lead screw or guide rod 26. This design enables the fixture 1 to be stably and accurately installed on the boring bar 24, providing a reliable mounting foundation for the detection device and solving the problem of difficulty in installing a dial indicator on the boring bar 24. Regarding the issue of deviations introduced by the selection of measurement points and the control of measurement force, the fixture body 11 also features a mounting surface 15 on its outer side, with the detection device fixedly mounted on this surface and oriented towards the transmission lead screw or guide rod 26. This fixed installation method of the testing device allows for precise pre-setting of its position relative to the lead screw or guide rod 26 of the boring bar 24, avoiding arbitrary selection of measurement points. Furthermore, since the testing device is fixedly installed, it eliminates the need for manual control of the measuring force during measurement, unlike dial indicators, thus reducing deviations caused by improper force control. Finally, addressing the issue of deviations introduced by the minor vibrations of the boring bar 24 itself, the fixture body 11, through the engagement of the positioning key 14 with the positioning groove 241 on the boring bar 24 and the structure of the fixture body 11 fitted onto the boring bar 24, forms a relatively stable whole with the boring bar 24. This structure can reduce the impact of minor vibrations of the boring bar 24 on the testing device to a certain extent, because the testing device is fixed to the fixture 1. The stability of the fixture 1 ensures that the relative position of the testing device remains unchanged during the measurement process, thereby improving measurement accuracy and solving the problem of deviations introduced by the minor vibrations of the boring bar 24 itself. Furthermore, by reducing offsets and errors during the debugging process, the fixture 1 can speed up the debugging process and shorten the installation and debugging cycle; the close cooperation between the fixture 1 and the boring bar 24 ensures the accuracy of the measurement, thereby improving the overall accuracy of the machine tool; due to the shortened debugging cycle and improved efficiency, the fixture 1 can reduce the input of labor costs.
