Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, specifically to an inverted gear turning machine with automatic workpiece spindle loading and unloading. Background Technology

[0002] Gear turning machines are mainly used for machining internal / external gears. One type of gear turning machine has the following configuration: the workpiece turntable rotates horizontally, and the gear cutting cutter moves laterally and longitudinally on the horizontal plane to machine the workpiece on the turntable. Traditional gear machining methods mostly involve gear shaping, hobbing, and milling, which involve multiple transmission links, resulting in low positioning accuracy and machining efficiency. Furthermore, existing gear turning machines have an inefficient layout, occupy space, have low automation, and struggle to achieve precise multi-angle feed.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a gear turning machine [CN202010216638.4], which includes a six-axis, four-linkage machining method. The X-axis, composed of parts such as the machine bed, is responsible for radial depth of cut; the Z-axis, composed of parts such as the machine column, is responsible for axial cutting feed; the C-axis is responsible for workpiece rotation; and the B-axis is responsible for tool rotation. Workpiece clamping and cooling are provided with hydraulic pressure by a hydraulic station connected by oil pipes; the A-axis, composed of parts such as the A-axis slide and the column slide, is responsible for adjusting the tool angle; and the Y-axis, composed of parts such as the A-axis slide, is responsible for adjusting the tool center.

[0004] The above solution has solved the problem of low positioning accuracy and processing efficiency caused by multiple transmission links in the gear turning machine in the existing technology to a certain extent. However, the solution still has many shortcomings, such as: the layout is not compact enough, it occupies space, and the degree of automation is low, making it difficult to achieve precise multi-angle feeding.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-6 As shown, an inverted gear turning machine with automatic workpiece spindle loading and unloading includes a frame base 1, a transverse propulsion seat 2 slidably disposed on the frame base 1, an automated material hopper assembly 3 disposed at one end of the transverse propulsion seat 2, a lifting feed gear shaft assembly 4 disposed on the side of the transverse propulsion seat 2 near the automated material hopper assembly 3, and a rotating gear cutting mechanism 6 connected to the inner circumference of the automated material hopper assembly 3 through a longitudinal sliding structure 5. The output ends of the lifting feed gear shaft assembly 4 and the rotating gear cutting mechanism 6 process the workpiece located on the automated material hopper assembly 3.

[0024] The transverse propulsion seat 2 includes slide rails 21 arranged symmetrically on the upper surface of the frame base 1. A positioning plate 22 is provided at the bottom of the slide rail 21, and a positioning protrusion 23 is provided on one side of the positioning plate 22 facing each other. The slide rail 21 is positioned on the positioning plate 22 and is limited on one side by the positioning protrusion 23. A plurality of sliders 24 are slidably arranged on the slide rail 21, and the upper surface of the sliders 24 is connected to the connecting pad 25 provided at the bottom of the transverse propulsion seat 2.

[0025] An external propulsion motor is provided to drive the transverse propulsion seat 2 to move on the slide rail 21. The movement of the transverse propulsion seat 2 controls the machining position of the machining spindle 46 and realizes the feed in the X-axis direction.

[0026] As can be seen, the lifting feed gear assembly 4 includes a slide rail positioning surface 41 disposed at one end of the transverse propulsion seat 2 near the automated hopper assembly 3. A lifting slide rail 43 is connected to the slide rail positioning surface 41 via a slide rail mounting seat 42. A spindle seat 45 is slidably connected to the lifting slide rail 43 via several connecting sliders 44. A machining spindle 46 is disposed on the spindle seat 45.

[0027] Obviously, the upper end of the transverse propulsion seat 2 is connected to the lifting control cylinder 48 via the cylinder positioning seat 47. The output end of the lifting control cylinder 48 extends toward the interior of the transverse propulsion seat 2 and its end is connected to the main shaft seat 45 via the linkage plate 49. One end of the transverse propulsion seat 2 has a clearance channel 26 through which the linkage plate 49 can pass.

[0028] The lifting control cylinder 48 drives the spindle seat 45 to move up and down, thereby controlling the feed of the machining spindle 46 in the Z-axis direction.

[0029] Furthermore, the upper end of the machining spindle 46 has a rotation drive motor 461, which is positioned in the annular positioning cylinder 463 on the spindle seat 45 via a positioning flange 462. A positioning seat 464 is provided at the bottom of the annular positioning cylinder 463, and a proximity switch 465 is provided on the positioning seat 464. A rotation limit sensor 466 is provided circumferentially on the positioning flange 462.

[0030] The distance between the workpiece and the machining spindle 46 can be sensed by the proximity switch 465, and the rotation limit sensor 466 is used to control the rotation machining range of the machining spindle.

[0031] Furthermore, a lifting limit control slide rod 7 is provided on the slide rail positioning surface 41 and on one side of any slide rail mounting base 42. An infrared distance sensor 71 is provided at the upper end of one side of the lifting limit control slide rod 7 and a sensing module 72 corresponding to the infrared distance sensor 71 is provided at the lower end. The infrared distance sensor 71 is connected to the connecting slider 44.

[0032] The feed length of the machining spindle 46 in the Z-axis direction is controlled by using an infrared distance sensor 71 in conjunction with a sensing module 72 to ensure machining accuracy.

[0033] Specifically, the automated silo assembly 3 includes an annular feeding frame 31, on which a sliding guide channel 32 is provided, and a plurality of material positioning seats 33 are equidistantly arranged in the sliding guide channel 32. A stepper drive motor 34 is provided at the bottom of the annular feeding frame 31 for driving the material positioning seats 33 in the sliding guide channel 32 to move gradually, and a connecting bracket 35 is provided at the upper end of the stepper drive motor 34 for supporting and connecting the annular feeding frame 31.

[0034] The material positioning seat 33 is used to position the workpiece to be processed, and the bottom of the material positioning seat 33 is provided with a transmission chain connected to the output end of the stepper drive motor 34.

[0035] More specifically, the longitudinal sliding structure 5 includes a longitudinally arranged guide rail 51, a plurality of connecting sliders 52 are slidably arranged on the upper end of the guide rail 51, and a rotating frame 53 is connected to the upper end of the connecting sliders 52. A sliding drive motor 54 for driving the rotating frame 53 to slide is provided at one end of the guide rail 51.

[0036] The rotating frame 53 is driven by the sliding drive motor 54 to move on the connecting slider 52, thereby controlling the movement of the gear cutting tool 65 in the Y direction.

[0037] In detail, the rotary gear cutting mechanism 6 is equipped with a rotary adjustment motor 61 on the rotary frame 53. The output end of the rotary adjustment motor 61 is provided with a rotary mounting plate 62. A rotary gear cutting motor 64 is mounted on the rotary mounting plate 62 via a motor frame 63. The output end of the rotary gear cutting motor 64 is oriented upward and connected to a gear cutting tool 65.

[0038] Rotating the mounting plate 6 drives the motor frame 63 to rotate in conjunction, thereby controlling the angle adjustment of the cutting tool 65 and realizing multi-angle machining.

[0039] Preferably, the upper surface of the frame base 1 is provided with a clearance slot 11 for the rotating gear motor 64 to rotate.

[0040] In summary, the principle of this embodiment is as follows: This scheme adopts an inverted layout, and the processed chips fall naturally, which can avoid blockage in the processing area; secondly, by moving the transverse propulsion seat 2 on the slide rail 21, the machining spindle 46 is fed in the X-axis direction, and the lifting control cylinder 48 drives the spindle seat 45 to move up and down, thereby controlling the feed of the machining spindle 46 in the Z-axis direction. At the same time, the sliding drive motor 54 drives the rotating frame 53 to move on the connecting slider 52, thereby controlling the movement of the gear cutting tool 65 in the Y-axis direction, thus realizing three-dimensional angle processing and improving processing accuracy and processing quality.

[0041] This innovative solution arranges the automated hopper component 3 circumferentially outside the longitudinal sliding structure 5 and the rotating gear cutting mechanism 6, reducing space occupation and making the spatial layout more compact. This facilitates the placement of multiple devices in a limited space or integration with other production line equipment.
