[0014] The present invention will be described in detail below with reference to the attached drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0015] The following detailed descriptions are all exemplary descriptions, aiming to provide further detailed explanations for the present invention. Unless otherwise specified, all technical terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present invention.

[0016] Please refer to Figure 1 As shown, the present invention provides an integrated composite machining tool, including a machine body 1, a first workpiece shaft device 2, a second workpiece shaft device 3, a first workpiece shaft driving device 4, a second workpiece shaft driving device 5, a spindle moving guide rail 6, a first turret assembly 7, a second turret assembly 8, a first turret driving device 9, a second turret driving device 10, a first turret moving guide rail 11, a second turret moving guide rail 12, a chip removal device connection hole position 13, a first turret horizontal guide rail 14, a first turret vertical guide rail 15, a second turret horizontal guide rail 16, and a second turret vertical guide rail 17.

[0017] The machine body 1 is generally wedge-shaped and has opposite left and right side structures. The first workpiece shaft device 2 and the second workpiece shaft device 3 are respectively arranged on the left and right sides of the machine body 1 for clamping workpieces.

[0018] The first workpiece shaft device 2 and the second workpiece shaft device 3 are coaxial, and the common axis is the workpiece machining center axis.

[0019] The spindle moving guide rail 6 is arranged on the wedge-shaped surface of the machine body 1. The spindle moving guide rail 6 is located in the middle of the machine body 1, parallel to the machining center axis, and is respectively connected to the first workpiece shaft device 2 and the second workpiece shaft device 3 on the left and right, providing a moving path for workpiece clamping conversion.

[0020] The first workpiece shaft driving device 4 and the second workpiece shaft driving device 5 are respectively arranged on the left and right sides of the machine body 1. The first workpiece shaft driving device 4 and the second workpiece shaft driving device 5 are connected to each other through the spindle moving guide rail 6, and are respectively connected to the first workpiece shaft device 2 and the second workpiece shaft device 3. Under the action of the first workpiece shaft driving device 4 and the second workpiece shaft driving device 5, the first workpiece shaft device 2 and the second workpiece shaft device 3 can move relative to each other through the spindle moving guide rail 6 to transfer the clamped workpieces.

[0021] Both the first workpiece shaft device 2 and the second workpiece shaft device 3 can clamp workpieces. Generally, the workpiece is first clamped on the first workpiece shaft device 2, and the first turret assembly 7 and the second turret assembly 8 can drive the tools to process the workpiece simultaneously. Then the workpiece is clamped on the second workpiece shaft device 3. Since the clamped position of the workpiece changes, the tool held by the second turret assembly 8 can process the side of the first clamping part.

[0022] When it is necessary to change the clamping direction of the workpiece, it is driven by the first workpiece shaft driving device 4 and the second workpiece shaft driving device 5, so that the first workpiece shaft device 2 and the second workpiece shaft device 3 can move closer to each other along the main shaft moving guide rail 6. At this time, the second workpiece shaft device 3 can directly clamp the other end of the workpiece, and then the first workpiece shaft device 2 releases the workpiece, that is, the conversion docking of the workpiece is completed, and then the next processing procedure can be continued. This kind of workpiece clamping conversion can be completed within the machine tool, with high speed and efficiency, shortening the processing beat, and does not require the use of an additional handling robot to handle the workpiece. In addition, since the first workpiece shaft device 2 and the second workpiece shaft device 3 are coaxial, after the clamping position of the workpiece is switched, the initial position of the tool can be calculated by the control program of the machine tool, and there is no need to readjust the initial position of the tool, shortening the tool setting time.

[0023] The first turret moving guide rail 11 and the second turret moving guide rail 12 are arranged on the wedge-shaped surface of the bed body 1. The first turret moving guide rail 11 and the second turret moving guide rail 12 are integrally distributed on the upper and lower sides of the bed body 1, and both include a guide rail parallel to the machining center axis and a guide rail perpendicular to the machining center axis along the wedge-shaped surface of the bed body 1, so as to realize the horizontal and vertical movement of the first turret assembly 7 and the second turret assembly 8 with respect to the machining center axis.

[0024] Among them, the first turret horizontal guide rail 14 and the second turret horizontal guide rail 16 are parallel to the main shaft moving guide rail 6 and are directly connected to the bed body 1. The first turret vertical guide rail 15 and the second turret vertical guide rail 17 are respectively mounted on the first turret horizontal guide rail 14 and the second turret horizontal guide rail 16, and the guide rail direction is perpendicular to the machining center axis.

[0025] The guiding length of the second turret horizontal guide rail 16 spans the first workpiece shaft device 2 and the second workpiece shaft device 3 to provide a long enough horizontal movement stroke for the second turret assembly 8 to participate in the machining of the workpiece in the clamped state of the first workpiece shaft device 2 and the second workpiece shaft device 3. Similarly, since the first turret assembly 8 only participates in the machining of the workpiece in the clamped state of the first workpiece shaft device 2, the length of the first turret horizontal guide rail 14 only needs to meet the requirement that the first turret assembly 8 can reach the first workpiece shaft device 2.

[0026] The first turret assembly 7 and the second turret assembly 8 are respectively installed on the upper and lower sides of the bed body 1. One end of the first turret assembly 7 facing the left side of the bed body 1 is used to install the tool, and one end of the second turret assembly 8 facing the right side of the bed body 1 is used to install the tool.

[0027] The first turret assembly 7 and the second turret assembly 8 are respectively provided with a first turret driving device 9 and a second turret driving device 10. The first turret assembly 7 and the second turret assembly 8 can respectively move perpendicular and parallel to the machining center axis under the action of the first turret driving device 9 and the second turret driving device 10 through the first turret moving guide rail 11 and the second turret moving guide rail 12.

[0028] The first turret assembly 7 can be configured with turning tools, and the second turret assembly 8 can be configured with turning tools and drills at the same time. For simple hole machining implementation schemes, the drill can be replaced with a milling cutter because both the milling cutter and the drill belong to the scheme of tool self-rotation. When the first workpiece shaft device 2 clamps the workpiece and rotates around the axis, the second turret assembly 8 moves along the second turret moving guide rail 12 towards the first workpiece shaft device 2 to the machining position under the action of the second workpiece shaft device 3, and turns the workpiece clamped by the first workpiece shaft device 2 simultaneously with the first turret assembly 7. When the second workpiece shaft device 3 clamps the workpiece and rotates around the axis, the second turret assembly 8 switches to the turning tool position to machine the workpiece. When holes need to be machined, the second workpiece shaft device 3 clamps the workpiece and remains stationary. Under the action of the second turret driving device 10, the second turret assembly 8 switches to the tool position where the drill is located and rotates around the tool axis to machine the workpiece.

[0029] The first turret driving device 9 and the second turret driving device 10 have a rotational driving function. Through rotational driving, the turret assembly can achieve circumferential rotation to realize the tool changing action and drilling function during the workpiece machining process.

[0030] The first turret driving device 9 and the second turret driving device 10 can realize the switching function between the tools carried by the first turret assembly 7 and the second turret assembly 8, and can also realize the movement of both parallel and perpendicular to the machining center axis. Specifically, when the first workpiece shaft device 2 clamps the workpiece, the first turret driving device 9 drives the first turret assembly 7 to move to the first workpiece shaft device 2, and the second turret driving device 10 drives the second turret assembly 8 to move to the first workpiece shaft device 2 to machine the clamped workpiece. Then, when the workpiece is transferred to the second workpiece shaft device 3, the second turret driving device 10 can continue to drive the second turret assembly 8 to move to the second workpiece shaft device 3 to machine the workpiece clamped on the second workpiece shaft device 3 to complete the machining of the entire workpiece. This solution realizes the switching machining of the clamping side of the workpiece on one machine tool without using an additional handling robot to handle and switch the clamping side of the workpiece.

[0031] In a specific embodiment, both the left and right sides of the machine body 1 are provided with reserved chip removal device connection holes 13 for connecting with the chip removal device to discharge the machining debris generated during the machining process. The direction of the chip removal device can be selected during actual use, which is beneficial to increasing the space utilization rate.

[0032] In a specific embodiment, the first workpiece spindle device 2 and the second workpiece spindle device 3 adopt the spindle structure of a traditional horizontal lathe, that is, the first workpiece spindle device 2 can clamp the workpiece to be machined and rotate around the axis, and the same applies to the second workpiece spindle device 3.

[0033] In a specific embodiment, the first workpiece spindle device 2 and the second workpiece spindle device 3 are coaxial, which is convenient for the machine tool control system to control the movement of the first turret assembly 7 and the second turret assembly 8 and calculate the tool feed rate during machining.

[0034] Such as Figure 2 、 3 As shown in the figure, taking the machining of a wheel 100 as an example, the following positions of the wheel 100 can be machined using this solution: the outer rim 101, the inner rim 102, the back cavity 103, the flange surface 104, the center hole 105, the cap 106, the front surface 107, and the screw hole 110.

[0035] During the actual machining process, the wheel 100 is first clamped on the first workpiece spindle device 2. Specifically, the first workpiece spindle device 2 clamps the outer rim 108 position on the A-side of the wheel 100. Under the action of the first turret driving device 9 and the second turret driving device 10, the first turret assembly 7 and the second turret assembly 8 respectively move along the first turret movement guide rail 11 and the second turret movement guide rail 12 to the first workpiece spindle device 2. Subsequently, the tools carried by the first turret assembly 7 machine the inner rim 102, the back cavity 103, the flange surface 104, and the center hole 105 of the wheel 100, and the tools carried by the second turret assembly 8 machine the outer rim 101 of the wheel 100.

[0036] After the workpiece is machined at the first workpiece spindle device 2, under the action of the first workpiece spindle driving device 9 and the second workpiece spindle driving device 10, the first workpiece spindle device 2 and the second workpiece spindle device 3 approach each other along the spindle movement guide rail 6. The second workpiece spindle device 3 clamps the inner rim 109 position on the B-side of the wheel 100. Then the first workpiece spindle device 2 releases the wheel 100, and the second workpiece spindle device 3 clamps the wheel 100 and returns to the right side of the bed 1. While the first workpiece spindle device 2 and the second workpiece spindle device 3 exchange the workpiece clamping, the second turret assembly 8 can return to the right side of the bed 1 along the second turret movement guide rail 12 under the action of the second turret driving device 10 to prepare for machining the unprocessed part of the wheel 100.

[0037] When the wheel 100 is clamped by the second workpiece shaft device 3, the second turret assembly 8 first drives the cutting tool to perform turning on the remaining unprocessed parts of the wheel 100, including the unprocessed outer rim 101, the rim edge 106, and the front face 107. Finally, drilling is carried out. At this time, the second workpiece shaft device 3 needs to remain stationary. Under the action of the second turret drive device 10, the second turret assembly 8 adjusts the cutting tool to the drill bit (or milling cutter) position and drives the drill bit (or milling cutter) to rotate around its own central axis, that is, parallel to the machining center axis, for machining the bolt holes 110 of the wheel 100.

[0038] In the integrated composite machining machine tool of the present invention, not only can the turning function of the wheel 100 on the traditional machining units of the first and second lathes be completed, but also the drilling function can be integrated to realize the machining of the bolt holes of the wheel 100. Compared with the traditional wheel machining unit, the integrated composite machining machine tool of the present invention does not need to use a manipulator to realize the conversion of the wheel 100 clamping, and at the same time saves the door opening and closing time of the machine tool, making the production rhythm faster. Moreover, compared with setting up multiple machine tools, the floor area of the machine tool of the present invention is also smaller.

[0039] As is known by common technical knowledge, the present invention can be implemented by other embodiments without departing from its spirit or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or equivalent to the present invention are encompassed by the present invention.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: the specific implementation manners of the present invention can still be modified or equivalently replaced, and any modification or equivalent replacement without departing from the spirit and scope of the present invention should be covered by the protection scope of the claims of the present invention.
