[0011] As a preferred embodiment of the present invention, the slider is slidably connected to the inner wall of the installation groove, and a positioning plate is installed at one end of the slider extending to the outer wall of the installation groove.

[0012] As a preferred embodiment of the present invention, the displacement assembly includes an installation base plate, which is arranged on the base surface of the installation plate.

The sealing assembly is located on one side of the displacement assembly. The first slide rail is located on one side of the servo module. The sealing gasket is made of rubber material.

[0014] As a preferred embodiment of the present invention, both the adjustment assembly and the displacement assembly are located in the inner cavity of the machine tool housing. The fixed disk is located directly below the mounting bracket, and there is a gap between the fixed disk and the mounting bracket. Multiple groups of electromagnets are arranged on the bottom outer wall of the fixed disk and are in an annular structure. Multiple groups of fixing plates are arranged on the inner walls of the installation grooves respectively. Multiple groups of sliders are arranged on the inner walls of the installation grooves respectively.

[0015] Compared with the prior art, the specific beneficial effects of the present invention are as follows: By arranging an adjusting component in the arc curve gear production machine tool, the rotating motor is operated to drive the fixed disk and the cutting blade to rotate, and the processed gear is rotationally cut. When vertical cutting is required, the servo motor drives the reel to contract the limit rope, the slider moves horizontally and is magnetically fixed by the electromagnetic magnet. At the same time, the control panel controls one group of electromagnetic magnets to stop operating. At this time, the compressed limit spring exerts an elastic thrust on the slider to reset the slider. The movement of the slider drives the fixed seat and the cutting blade to a suitable position. The electric control telescopic cylinder drives the fixed frame to move vertically, and drives the rotating motor and the cutting blade to move vertically and reciprocally through the limit block, realizing the vertical cutting tooth groove processing of the processed gear, thus solving the problem that the processing blade cannot be accurately adjusted to adapt to the complex processing angle of the longitudinally bent gear, resulting in the need for multiple different devices to cooperate for pin insertion or milling, increasing the production complexity.

[0016] In the present invention, by arranging an adjusting component in the arc curve gear production machine tool, the limit rope is wound and contracted by the reel. When the limit rope contracts to a suitable length, the slider is forced to move horizontally on the inner wall of the installation groove to a suitable position. Subsequently, the control panel controls the electromagnetic magnet to magnetically fix the positioning plate to a suitable position. Then, the control panel controls the electromagnetic magnet on one side to lose power and magnetism, so that the positioning plate on one side loses fixation. At this time, the compressed limit spring exerts an elastic thrust on the slider to reset. At this time, one group of positioning plates is magnetically fixed by the electromagnetic magnet, and the other group of positioning plates is elastically reset by the limit spring. There is a certain gap between the two, so that there is a gap between the two groups of cutting blades. When the fixed disk drives the two groups of cutting blades to rotate and cut at the same time, due to the inconsistent center of the tooth groove arc angle, first, the two groups of cutting blades at different positions rotate, so that they simultaneously perform rough machining and grooving of two groups of tooth grooves on the processed gear. Subsequently, when the rough machining of the tooth grooves is completed, the fixed disk drives the reset cutting blade to perform finish machining on the tooth grooves of the processed gear, so that the tooth grooves of the processed gear meet the requirements. Compared with the sequential tooth groove processing, the processing efficiency of two tooth grooves is higher, thus solving the problem that when the current machine tool processes longitudinally bent gears, the method of processing one tooth groove sequentially one by one seriously affects the production efficiency and makes the overall production cycle long when facing a large number of processing.

[0017] The present invention arranges a closed component in an arc curve gear production machine tool, and applies a pulling force to a door panel so that the door panel is forced to move in the inner cavity of a machine tool shell. When the door panel moves, the door panel simultaneously drives the first fixed block and the second fixed block to move, thereby making the door panel fit and be fixed at the port of the machine tool shell. Since the door panel is respectively supported by a plurality of groups of first connecting plates and the second connecting plates, the overall stability of the door panel is better. The sealing gasket arranged on the side wall of the door panel improves the sealing performance of the door panel and the machine tool shell, thereby solving the problem that the guide rail support structure of the machine tool safety door is prone to wear due to frequent use, external force impact or long-term wear, which not only reduces the operational safety but also affects the continuity and stability of production.

A rotating base 611 is rotatably connected to the outer wall on the other side of the limiting block 609. A rotating motor 612 is mounted on the outer wall of the rotating base 611. One end of the rotating base 611 is connected to the driving shaft of the driving motor 610. One end of the rotating motor 612 is mounted with a fixing disk 613.

A limiting spring 617 is mounted on the outer wall of the fixing plate 616. One end of the limiting spring 617 is mounted with a slider 618. The slider 618 is slidably connected to the inner wall of the installation groove 614, and one end of the slider 618 extends to the outer wall of the installation groove 614 to be mounted with a positioning plate 619.

A servo motor 623 is arranged in the middle of the inner cavity of the fixing disk 613. A winding drum 624 is mounted on the driving shaft of the servo motor 623. The limiting rope 622 is connected to the outer wall of the winding drum 624.

[0024] Under the action of the above structural features and connection relationships, a length meter is arranged on the inner wall of the winding drum 624, so that when the winding drum 624 winds up the limiting rope 622, the length meter measures the length of the limiting rope 622; In this embodiment, specifically refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 9 and Figure 10, the displacement component 7 includes a mounting base plate 701 which is arranged on the base surface of the mounting plate 5. A servo module 702 is mounted on the outer wall of the mounting base plate 701. A processing base 703 is mounted on the moving surface of the servo module 702. A rotating base 704 is mounted on the outer wall of the processing base 703. A top rod 705 is mounted on the top outer wall of the rotating base 704. A clamp 706 is mounted at one end of the top rod 705. A processing gear 707 is mounted on the outer wall of the top rod 705. A transmission gear 708 is mounted on the outer wall of the top rod 705. A stepping motor 709 is mounted on the side wall of the processing base 703. A driving gear 710 is mounted on the driving shaft of the stepping motor 709. The connection mode between the driving gear 710 and the transmission gear 708 is meshing connection.

[0025] Under the action of the above structural features and connection relationships, the processing gear 707 is located directly below the cutting blade 621, so that when the cutting blade 621 rotates, driven by the electric control telescopic cylinder 606, the cutting blade 621 can perform cutting processing on the processing gear 707. Among them, the control panel 4 is respectively connected to the electric control spray head 602, the electric control cylinder 604, the electric control telescopic cylinder 606, the driving motor 610, the rotating motor 612, the electric control magnet 615, the servo motor 623, the servo module 702 and the stepping motor 709 through wires and is in an electrically connected state, enabling the device to be powered on. Then the control panel 4 controls the electric control spray head 602, the electric control cylinder 604, the electric control telescopic cylinder 606, the driving motor 610, the rotating motor 612, the electric control magnet 615, the servo motor 623, the servo module 702 and the stepping motor 709 to be powered on and operate. The sealing component 3 is located on one side of the displacement component 7. The first slide rail 301 is located on one side of the servo module 702. The sealing gasket 308 is made of rubber material. Both the adjustment component 6 and the displacement component 7 are located in the inner cavity of the machine tool housing 2. The fixed disk 613 is located directly below the mounting bracket 603, and there is a gap between the fixed disk 613 and the mounting bracket 603. Multiple groups of electric control magnets 615 are respectively arranged on the bottom outer wall of the fixed disk 613, and the electric control magnets 615 are in an annular structure. Multiple groups of fixing plates 616 are respectively arranged on the inner wall of the mounting groove 614. Multiple groups of sliders 618 are respectively arranged on the inner wall of the mounting groove 614. A handle is arranged on the outer wall of the door panel 307.

[0026] When the arc curve gear production machine tool of this solution is working, a pulling force is applied to the door panel 307, causing the door panel 307 to move under force within the inner cavity of the machine tool housing 2. When the door panel 307 moves, it will drive the first fixed block 306 and the second fixed block 312 to move simultaneously. When the first fixed block 306 moves, it will apply a pulling force to the first connecting plate 304, thereby causing the first connecting plate 304 to apply a pulling force to the first rotating rod 303, making the first rotating rod 303 move to one side along the inner wall of the first slide rail 301. At the same time, when the second fixed block 312 moves, it will apply a pulling force to the second connecting plate 310, thereby causing the second connecting plate 310 to apply a pulling force to the second rotating rod 309, making the second rotating rod 309 move to one side along the inner wall of the second slide rail 302. Thus, the door panel 307 is fixed by fitting against the port of the machine tool housing 2. Since the door panel 307 is supported by multiple groups of the first connecting plate 304 and the second connecting plate 310 respectively, the overall stability of the door panel 307 is better. The sealing gasket 308 provided on the side wall of the door panel 307 makes the sealing performance between the door panel 307 and the machine tool housing 2 better, thereby solving the problem that due to frequent use, external force impact or long-term wear, the guide rail support structure of the machine tool safety door is prone to wear, which not only reduces the operation safety but also affects the continuity and stability of production.

[0027] By turning on the switch of the control panel 4, the control panel 4 controls the operation of the servo module 702, so that the moving surface of the servo module 702 drives the processing base 703 to move horizontally, causing the processing base 703 to drive the displacement component 7 to move, and further causing the displacement component 7 to drive the processing gear 707 to move to the processing position. At the same time, the control panel 4 controls the operation of the stepping motor 709, so that the drive shaft of the stepping motor 709 drives the driving gear 710 to operate, so that the driving gear 710 drives the transmission gear 708 to operate through meshing connection, and further causes the transmission gear 708 to drive the ejector rod 705 to operate, and the ejector rod 705 drives the fixture 706 to rotate, so that the fixture 706 drives the processing gear 707 to operate for processing.

[0028] The electric control cylinder 604 is controlled by the control panel 4 to operate, so that one end of the electric control cylinder 604 applies a thrust to the positioning base plate 605, thereby causing the positioning base plate 605 to move vertically on the outer wall of the mounting column 601. When the positioning base plate 605 moves vertically, it will cause the positioning base plate 605 to drive the electric telescopic cylinder 606 to move vertically. Subsequently, one end of the electric telescopic cylinder 606 applies a thrust to the fixing bracket 607, so that the fixing bracket 607 moves downward, and then the fixing bracket 607 moves to a suitable position. Subsequently, the control panel 4 controls the driving motor 610 to operate, so that the driving shaft of the driving motor 610 applies a rotational thrust to the rotating base 611, thereby causing the rotating base 611 to drive the rotating motor 612 to rotate to adjust the angle of the rotating motor 612 for the machining of different arc curve gears.

[0029] By turning on the switch of the control panel 4, the control panel 4 controls the servo motor 623 to operate. When the servo motor 623 operates, the driving shaft of the servo motor 623 drives the reel 624 to operate, thereby causing the reel 624 to wind and contract the limit rope 622. When the limit rope 622 contracts, it will cause the limit rope 622 to apply a pulling force to the slider 618, causing the slider 618 to move horizontally on the inner wall of the mounting groove 614. At the same time, the slider 618 applies a squeezing force to the limit spring 617, thereby causing the limit spring 617 to be compressed. When the slider 618 drives the fixing seat 620 to move to a suitable position through the positioning plate 619, the control panel 4 controls the electromagnet 615 to be energized to generate magnetism, so that the electromagnet 615 generates magnetic adsorption on the positioning plate 619, causing the positioning plate 619 to be fixed in a suitable position. And since there are multiple groups of electromagnets 615, each group of electromagnets 615 can individually apply magnetic adsorption to the positioning plate 619, thereby causing the positioning plate 619 to stop in a suitable position. For the other unfixed positioning plates 619, due to the rebound of the compressed limit spring 617, the limit spring 617 applies a thrust to the slider 618 to reset the slider 618.

[0030] When operating through the rotation of the rotary motor 612, the rotary motor 612 drives the fixed disk 613 to operate. When the fixed disk 613 operates, the fixed disk 613 drives the cutting blade 621 to perform rotary cutting processing, so that the cutting blade 621 performs rotary cutting groove processing on the processed gear 707. At the same time, when vertical cutting processing is required, since the drive shaft of the servo motor 623 drives the reel 624 to operate, the reel 624 winds and contracts the limit rope 622. When the limit rope 622 contracts, the limit rope 622 exerts a pulling force on the slider 618, causing the slider 618 to move horizontally on the inner wall of the installation groove 614. Subsequently, the control panel 4 controls the electro-magnet 615 to magnetically fix the positioning plate 619, and at the same time, the control panel 4 controls one group of electro-magnets 615 to stop operating. At this time, the compressed limit spring 617 exerts an elastic thrust on the slider 618 to reset the slider 618. Since when a group of sliders 618 drive the fixed seat 620 to move to a suitable position through the positioning plate 619, the fixed seat 620 drives the cutting blade 621 to move to a suitable position. At this time, the electric control telescopic cylinder 606 performs reciprocating displacement up and down, so that the electric control telescopic cylinder 606 drives the fixed frame 607 to move vertically. At the same time, the fixed frame 607 drives the rotary motor 612 to move vertically through the limit block 609. When the rotary motor 612 moves vertically, the rotary motor 612 drives the cutting blade 621 on one side to perform vertical reciprocating movement through the fixed disk 613, so that the cutting blade 621 performs vertical cutting groove processing on the processed gear 707, thus solving the problem that the processing blade of the arc curve gear production machine tool cannot be accurately adjusted to adapt to the complex processing angle of the longitudinally curved gear, resulting in the need for multiple different devices to cooperate for pin insertion or milling, increasing the production complexity.

[0031] The drive shaft of the servo motor 623 drives the winding drum 624 to operate, thereby causing the winding drum 624 to wind and contract the limit rope 622. When the limit rope 622 contracts to an appropriate length, it will apply a certain pulling force to the slider 618, causing the slider 618 to move horizontally on the inner wall of the installation groove 614 to an appropriate position. Subsequently, the control panel 4 controls the electro-magnet 615 to magnetically fix the positioning plate 619, thereby fixing the slider 618 at an appropriate position in the installation groove 614. Then, the control panel 4 controls the electro-magnet 615 on one side to lose power and magnetism, so that the positioning plate 619 on one side loses its fixation. At this time, the compressed limit spring 617 applies an elastic thrust to the slider 618 to reset the slider 618. Since a set of sliders 618 drive the fixed seat 620 to move and reset through the positioning plate 619, the fixed seat 620 drives the cutting blade 621 to reset. At this time, a set of positioning plates 619 are magnetically fixed by the electro-magnet 615, and the other set of positioning plates 619 are elastically reset by the limit spring 617. There is a certain gap between them, so that there is a gap between the two sets of cutting blades 621. When the fixed disk 613 drives the two sets of cutting blades 621 to rotate for cutting processing at the same time, due to the inconsistent centers of the tooth groove arcs, first, the two sets of cutting blades 621 at different positions rotate, so that they simultaneously perform rough machining on two tooth grooves of the processed gear 707 to open grooves. Subsequently, when the rough machining of the tooth grooves is completed, the fixed disk 613 drives the reset cutting blades 621 to perform finish machining on the tooth grooves of the processed gear 707, so that the tooth grooves of the processed gear 707 meet the requirements. Compared with the sequential tooth groove machining, the machining efficiency of two tooth grooves is higher, thus solving the problem that when the current machine tool processes longitudinally bent gears, the method of processing each tooth groove sequentially, in the face of a large number of processing, seriously affects the production efficiency and makes the overall production cycle long.

The scope of the present invention is defined by the appended claims and their equivalents.
