Automotive parts, as the foundation of the automotive industry, are a necessary factor supporting its continued healthy development. There are many types of automotive parts, with shaft parts accounting for a large proportion.

[0003] The cutting tools used in common shaft machining lathes are fixed or single-axis feed, and the tools cannot be freely adjusted in multiple directions. This makes it difficult to accurately control the cutting depth and angle during machining, thus affecting the machining accuracy of the parts. When machining parts with complex shapes, it may not be well adapted. In order to address the above problems, a lathe for machining automotive parts is proposed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a lathe for machining automotive parts. It solves the problem that the cutting tools used in the current common shaft machining lathes are fixed or single-axis feed, and the tools cannot be freely adjusted in multiple directions. This makes it difficult to accurately control the cutting depth and angle during the machining process, thereby affecting the machining accuracy of the parts. It may not be able to adapt well when machining parts with complex shapes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a lathe for processing automotive parts, including a machine housing, a gearbox fixedly connected to the upper right side of the machine housing, a three-jaw chuck fixedly connected to the right output end of the gearbox via a coupling, a drive source fixedly installed on the left side of the gearbox on the upper side of the machine housing, the output end of the drive source being fixedly connected to the input end of the gearbox via a coupling, support rods fixedly connected to the four corners of the gearbox on the upper side of the machine housing, and processing components arranged on the four support rods.

[0006] Preferably, the processing component includes a fixed plate, which is fixedly connected above the four support rods. The left and right sides above the fixed plate are fixedly connected to first sliding guide rails via pads, and a movable plate is slidably connected above the two sets of first sliding guide rails via sliding blocks.

[0007] Preferably, two sets of first connecting seats are fixedly connected between two sets of first sliding guide rails on the fixed plate, and a first lead screw is rotatably connected between the two sets of first connecting seats. A first threaded seat is threadedly connected to the outer surface of the first lead screw, and the top of the first threaded seat is fixedly connected to the middle of the bottom surface of the moving plate. A first servo motor for driving the first lead screw to rotate is fixedly installed on the front side above the fixed plate.

[0008] Preferably, the movable plate is fixedly connected to the front and rear sides with second sliding guide rails, and cantilever is slidably connected above the two sets of second sliding guide rails by sliding blocks. The upper surface of the movable plate is provided with two sets of sliding grooves between the two sets of second sliding guide rails.

[0009] Preferably, the upper surface of the movable plate is fixedly connected to two second connecting seats between two sets of sliding grooves, and a second lead screw is rotatably connected between the two second connecting seats.

[0012] Compared with existing technologies, the advantages of this utility model are as follows: This utility model addresses the shortcomings of traditional lathes with "fixed tool or single-axis feed" by designing an independent dual-axis drive structure. The dual-axis collaboration allows the tool to cover the entire machined surface of the part, making it particularly suitable for the complex "multi-step, multi-groove" structures of automotive axle parts. Through X / Y axis feed, the tool can move freely in multiple directions, enabling more precise cutting according to the specific shape of the workpiece. This significantly improves machining accuracy, especially when machining complex parts or workpieces with multiple different machined surfaces, reducing errors and achieving higher precision. It greatly expands machining capabilities. For complex curved surfaces or irregularly shaped parts, it enables flexible toolpath planning, ensuring precise machining of all surfaces. Tool rotation and multi-axis control allow multiple machining tasks to be completed in one operation, avoiding the hassle of multiple clamping operations, shortening machining time, and improving production efficiency.

[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0017] Reference Figure 1 - Figure 5As shown, a lathe for machining automotive parts includes a housing 1. A gearbox 3 is fixedly connected to the upper right side of the housing 1. The gearbox 3 can adjust the speed through internal gear transmission. A three-jaw chuck 4 is fixedly connected to the output end of the gearbox 3 via a coupling. A drive source 5 is fixedly installed on the left side of the gearbox 3 on the upper part of the housing 1. The drive source 5 can be a worm gear reducer. The output end of the drive source 5 is fixedly connected to the input end of the gearbox 3 via a coupling. The drive source 5, in conjunction with the speed change function of the gearbox 3, can output different speeds to meet the machining requirements of different parts. Support rods 2 are fixedly connected to the four corners of the gearbox 3 on the upper part of the housing 1. A machining component 6 is set on the four support rods 2. The four support rods 2 provide symmetrical support for the machining component 6, with uniform support strength, effectively preventing deformation of the machining component 6 due to its own weight or cutting force, and ensuring machining accuracy.

[0018] Specifically, the processing component 6 includes a fixed plate 601, which is fixedly connected to the top of four support rods 2. The left and right sides of the fixed plate 601 are fixedly connected to first sliding guide rails 602 by pads. The two sets of first sliding guide rails 602 are slidably connected to a moving plate 607 by sliding blocks. The first sliding guide rails 602 cooperate with the moving plate 607 connected to the upper sliding blocks to provide precise lateral sliding guidance for the moving plate 607. The precise cooperation between the guide rails and the sliding blocks ensures that the moving plate 607 slides without jamming or offset, ensuring the smoothness of the tool's lateral movement during processing and providing a stable motion trajectory for the lateral cutting of the parts.

[0019] Furthermore, two sets of first connecting seats 603 are fixedly connected between two sets of first sliding guide rails 602 on the fixed plate 601. A first lead screw 604 is rotatably connected between the two sets of first connecting seats 603. A first threaded seat 605 is threadedly connected to the outer surface of the first lead screw 604. The top of the first threaded seat 605 is fixedly connected to the middle of the bottom surface of the moving plate 607. A first servo motor 606 for driving the first lead screw 604 to rotate is fixedly installed on the front side above the fixed plate 601. The first servo motor 606 drives the first lead screw 604 to rotate, which can convert the rotational motion of the motor into the lateral linear motion of the moving plate 607. The high-precision control characteristics of the servo motor enable the moving distance and speed of the moving plate 607 to be precisely controlled, meeting the high-precision processing requirements of automotive parts. It has high transmission efficiency and no slippage, ensuring accurate processing dimensions.

[0020] Furthermore, the moving plate 607 is fixedly connected to the front and rear sides with second sliding guide rails 608. The two sets of second sliding guide rails 608 are slidably connected to the upper part of the two sets of second sliding guide rails 608 by sliding blocks. The upper surface of the moving plate 607 has two sets of sliding grooves 613 between the two sets of second sliding guide rails 608. The second sliding guide rails 608 cooperate with the cantilever 614 to provide precise front and rear sliding guidance for the cantilever 614, ensuring the stability of the cantilever 614 when driving the tool to move back and forth.

[0021] Furthermore, two second connecting seats 609 are fixedly connected between the two sets of sliding grooves 613 on the upper surface of the moving plate 607. A second lead screw 610 is rotatably connected between the two second connecting seats 609. A second threaded seat 611 is threadedly connected to the outer surface of the second lead screw 610. The top of the second threaded seat 611 is fixedly connected to the middle of the bottom surface of the cantilever 614. The second servo motor 612 drives the second lead screw 610 to rotate, which can convert the rotational motion into the forward and backward linear motion of the cantilever 614. The precise control of the servo motor allows the left and right movement distance of the cantilever 614 to be precisely adjusted to meet different cutting and machining requirements.

[0022] Furthermore, a second servo motor 612 for driving the second lead screw 610 to rotate is fixedly installed on the left side of the upper surface of the movable plate 607. Two sets of support bars 615 are fixedly connected to the bottom surface of the cantilever 614. The two sets of support bars 615 are slidably connected inside the two sets of sliding grooves 613 respectively. The support bars 615 slide synchronously along the sliding grooves 613, which can limit the back and forth sway of the cantilever 614 and ensure that the tool does not deviate during cutting. Especially when machining deep grooves and steps, it can avoid groove width deviation and uneven step end face caused by vibration.

[0023] Furthermore, a mounting plate 616 is fixedly connected to the upper right side of the cantilever 614, and a mounting base 617 is fixedly connected to the right side of the mounting plate 616. A drive shaft 618 is rotatably connected to the middle of the mounting base 617 via a bearing. A tool holder 621 is fixedly connected to the bottom end of the drive shaft 618. The tool holder 621 can quickly install different types of tools to adapt to the machining of different surfaces of automotive parts. The specific structure of the tool holder 621 is existing technology and will not be elaborated on here. A motor frame 619 is fixedly connected above the mounting base 617, and a third servo motor 620 is fixedly connected above the motor frame 619. The output end of the third servo motor 620 is fixedly connected to the top of the drive shaft 618 via a coupling.

[0024] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0025] Working principle: The automotive shaft part to be processed is placed in the center of the three-jaw chuck 4. The three-jaw chuck 4 is tightened manually or by a pneumatic device. According to the processing requirements, a suitable tool is selected and installed in the tool holder 621 under the cantilever 614. The tool is locked with bolts. During processing, the drive source 5 drives the gearbox 3 to rotate through the coupling. After the gearbox 3 decelerates and increases torque, it drives the three-jaw chuck 4 and the part to rotate synchronously. At the same time, the first servo motor 606 rotates forward at a preset speed, driving the first lead screw 604 to rotate clockwise. The first threaded seat 605 on the outer surface of the first lead screw 604 is threadedly connected to the lead screw, and the moving plate 607 cooperates with the first sliding guide rail 602 through a sliding block. Therefore, the first threaded seat 605 drives the moving plate 607 to move along the X-axis towards the part. As the tool moves, the moving plate 607 gradually approaches the part. After the X-axis feed is in place and the tool begins to cut the part, the second servo motor 612 rotates clockwise at a preset speed, driving the second lead screw 610 to rotate clockwise. The second threaded seat 611 is threadedly connected to the second lead screw 610, driving the cantilever 614 to move along the second sliding guide rail 608 to the right end of the part. The tool moves synchronously with the cantilever 614 and cuts along the axial direction of the part. When the part is machined to a position that requires a special angle, the third servo motor 620 is started according to the preset program. The motor drives the transmission shaft 618 to rotate at a set speed. The transmission shaft 618 drives the tool holder 621 and the tool to rotate synchronously, adjusting the tool angle to the preset value. During the tool rotation, the X-axis and Y-axis maintain feed, and the three work together to complete the complex machining.
