[0029] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] See also Figures 1 to 9 The worm gear virtual position measuring machine of the present invention comprises a frame 100, a fixture plate 200, a conveyor belt 300, a material transfer assembly 400 for transferring a motor gear box to be tested for virtual position to the conveyor belt 300, a worm rotation assembly 500 for rotating and loosening the worm in the motor gear box, and a virtual position detection assembly 600 for detecting the virtual position of the worm;

[0031] The conveyor belt 300 is installed on the frame 100, the fixture plate 200 is placed on the conveyor belt 300, the material transfer component 400 is arranged on one side of the conveyor belt 300, and the worm rotation component 500 and the virtual position detection component 600 are arranged in sequence along the transmission direction of the conveyor belt 300.

[0032] Among them, the frame 100 plays a role of fixing and supporting various structures of the worm gear virtual position measuring machine of the present invention, the feed seat 110 is used to accommodate the motor gear box to be tested, the conveyor belt 300 transfers the jig tray 200, and the jig tray 200 is placed on the conveyor belt 300, so that the jig tray 200 moves with the conveyor belt 300, and the motor gear box to be tested is placed in the jig tray 200, and the material transfer component 400 clamps the motor gear box placed in the feed seat 110 and rotates it 180°, and then places it in the jig tray 200. Of course, the material transfer component 400 can also directly transfer the motor gear box assembled from the outside to the jig tray 200 in the conveyor belt 300. The material transfer component 400 rotates 180° after clamping the motor gear box. °It is mainly to ensure that the motor gear box matches the fixture plate 200 and the equipment in the subsequent process. The fixture plate 200 equipped with the motor gear box moves with the conveyor belt 300. When passing through the worm rotating assembly 500, the worm rotating assembly 500 loosens the worm in the motor gear box to ensure that the worm can rotate normally. Then, the fixture plate 200 continues to move with the conveyor belt 300. The fork feeding assembly 700 is set between the conveyor belts 300.

[0033] The fork feeding assembly 700 can simultaneously feed multiple jig discs 200, thereby improving the movement efficiency of the jig disc 200 on the conveyor belt 300. When the fork feeding assembly 700 moves the jig disc 200 to pass through the virtual position detection assembly 600, the virtual position detection assembly 600 performs a virtual position detection action on the motor gear box. When the virtual position detection assembly 600 completes the virtual position detection action, the conveyor belt 300 transmits the detected motor gear box out of the device.

[0034] In this embodiment, the virtual position detection component 600 includes a motor gear box clamping component 610 for clamping the motor gear box, a worm clamping component 620 for clamping the worm in the motor gear box, and a worm detection component 630.

[0036] It is installed on the transverse fixed seat 622, and the output end of the centering drive device 624 is connected to the transverse adjustment seat 623, the vertical adjustment plate 625 is installed in the transverse adjustment seat 623, the worm tightening block 626 is slidingly connected to the vertical adjustment plate 625, the worm tightening drive cylinder 627 is installed on the vertical adjustment plate 625, and the output end of the worm tightening drive cylinder 627 is connected to the worm tightening block 626, the tightening rod driving cylinder 629 is installed on the worm tightening block 626, one end of the worm tightening rod 628 is connected to the output end of the tightening rod driving cylinder 629, and the other end of the worm tightening rod 628 extends out of the worm tightening block 626.

[0037] The worm tightening assembly 620 is used to tighten the motor gear box on the fixture plate 200, and the worm detection assembly 630 is used to perform a virtual position detection action on the worm in the motor gear box;

[0038] Specifically, the worm gear abutment bracket 621 plays a role of fixing and supporting various structures in the worm gear abutment assembly 620, and the centering drive device 624 drives the lateral adjustment seat 623 to slide on the side wall of the lateral fixed seat 622, so that the lateral adjustment seat 623 can drive the vertical adjustment plate 625 to match the position of the motor gear box, and the worm gear abutment drive cylinder 627 drives the worm gear abutment block 626 to make a vertical reciprocating motion on the vertical adjustment plate 625, so that the worm gear abutment block 626 approaches or moves away from the motor gear box, and then the worm gear abutment block 626 drives the worm gear abutment rod 628 to extend into the gap around the worm gear in the motor gear box.

[0039] When the worm gear clamping rod 628 extends into the gap on the worm, the clamping rod driving cylinder 629 enters the working state, so that the clamping rod driving cylinder 629 drives the worm gear clamping rod 628 to make a longitudinal displacement, thereby further clamping the worm, and the centering drive device 624 can be a cylinder.

[0040] In this embodiment, the worm detection assembly 630 includes a detection bracket 631, a detection drive cylinder 632 and a position detection sensor 633.

[0041] Among them, the worm detection component 630 is used to perform virtual position detection on the worm in the motor gear box, and the detection bracket 631 mainly plays a role of fixing and supporting various structures in the worm detection component 630. After the worm clamping component 620 clamps the worm in the motor gear box, the detection drive cylinder 632 drives the position detection sensor 633 to contact the worm clamping block 626. At this time, the worm clamping component 620 drives the worm clamping block 626 to reciprocate, so that the position detection sensor 633 detects the displacement offset of the worm clamping block 626, thereby obtaining the virtual position parameters of the worm in the motor gear box, thereby enabling the present invention to complete the virtual position measurement action of the worm in the motor gear box.

[0042] In this embodiment, the motor gear box clamping assembly 610 includes a clamping slide rail 611, a clamping driving cylinder 612 and a sliding clamping column 613. The clamping slide rail 611 is installed on the detection bracket 631, the clamping driving cylinder 612 is arranged on the side wall of the detection bracket 631, the sliding clamping column 613 is slidably connected to the clamping slide rail 611, and the output end of the clamping driving cylinder 612 is connected to the sliding clamping column 613.

[0043] Among them, the tightening driving cylinder 612 drives the sliding tightening column 613 to slide on the tightening slide rail 611 to tighten and fix the motor gear box in the fixture plate 200 on the conveyor belt 300, so as to improve the accuracy of the worm detection component 630 when performing the virtual position measurement action.

[0044] In this embodiment, a limiting protrusion for limiting the displacement of the worm is provided on the worm abutting rod 628 .

[0045] Among them, the limiting protrusion just cooperates with the gap of the worm shaft end in the motor gear box, so that the limiting protrusion can improve the clamping effect of the worm clamping rod 628 on the worm.

[0046] In this embodiment, the worm rotating assembly 500 includes a worm twisting bracket 510, a worm twisting baffle 520, a worm twisting vertical driving device 530, a worm twisting connecting plate 540, a worm abutting head 550, a worm twisting driving motor 560 for driving the worm abutting head 550 to rotate, a material transfer plate 570 and a material pressing head 580. The worm twisting bracket 510 is installed on the frame 100, the worm twisting baffle 520 is installed at the end of the worm twisting bracket 510, and the worm twisting vertical driving device 530 is installed on the frame 100. 530 is installed in the worm torsion baffle 520, the output end of the worm torsion vertical drive device 530 is connected to the worm torsion connecting plate 540, the worm clamping head 550 is installed on the lower side of the worm torsion connecting plate 540, the worm torsion drive motor 560 is installed on the upper side of the worm torsion connecting plate 540, and the output end of the worm torsion drive motor 560 is connected to the worm clamping head 550, the material transfer plate 570 is connected to the worm torsion baffle 520, and the material pressing head 580 is installed on the material transfer plate 570.

[0047] The worm torsion bracket 510 plays a role of fixing and supporting various structures in the worm rotating assembly 500. When the worm rotating assembly 500 needs to twist the worm in the motor gear box, the worm torsion vertical driving device 530 first enters the working state, and the worm torsion vertical driving device 530 drives the worm torsion connecting plate 540 to move downward, so that the worm torsion connecting plate 540 drives the worm torsion head 550 to connect to the motor gear box on the conveyor belt 300. At this time, the worm torsion driving motor 560 When entering the working state, the worm torsion drive motor 560 drives the worm clamping head 550 to rotate a certain angle, so that the worm clamping head 550 loosens the worm in the motor gear box, wherein the driving mode of the worm torsion vertical drive device 530 is a cylinder drive mode. At the same time, the material clamping head 580 is used to clamp with the motor gear box, so as to avoid the motor gear box shaking when the worm clamping head 550 loosens the worm in the motor gear box, thereby improving the loosening effect of the worm clamping head 550 on the worm.

[0048] In this embodiment, the worm rotating assembly 500 also includes a jig plate lifting assembly for lifting the jig plate 200 from the conveyor belt 300, and the jig plate lifting assembly includes a jig plate lifting bracket 591, a jig plate lifting guide rod 592, a jig plate support plate 593 and a jig plate lifting cylinder 594.

[0049] When the worm rotating assembly 500 needs to loosen the worm in the motor gear box, the jig plate lifting assembly first lifts the jig plate 200 out of the conveyor belt 300, so that the motor gear box and the worm rotating assembly 500 are matched;

[0050] Specifically, the jig tray lifting bracket 591 plays a role of fixing and supporting various structures in the jig tray lifting assembly. When the jig tray lifting assembly needs to lift the jig tray 200 from the conveyor belt 300, the jig tray lifting cylinder 594 enters the working state, so that the jig tray lifting cylinder 594 drives the jig tray support plate 593 to move upward until it is matched with the position of the worm rotating assembly 500. At the same time, the jig tray lifting guide rod 592 plays a role of limiting the jig tray support plate 593, thereby ensuring that the jig tray support plate 593 moves in the vertical direction.

When the fixture disk 200 moves to the preset position, the first fork lifting cylinder 730 and the second fork lifting cylinder 740 drive the fork feeding pallet 750 to return to the initial state, so that the fork feeding pallet 750 is retracted into the conveyor belt 300, thereby completing the overall feeding action of the fork feeding assembly 700.

[0056] Among them, the material transfer bracket 410 plays a role of fixed support for the entire material transfer component 400, and the material transfer longitudinal drive device 420 drives the material transfer vertical drive device 430 to reciprocate in the longitudinal direction, so that the material transfer vertical drive device 430 drives the rotating cylinder 440 to reciprocate in the vertical direction. When the material transfer component 400 needs to clamp and transfer the motor gear box in the feed seat 110, first, the material transfer longitudinal drive device 420 and the material transfer vertical drive device 430 cooperate with each other so that the material transfer claw cylinder 450 clamps the motor gear box on the feed seat 110, and at the same time, the rotating cylinder 440 enters the working state, so that the rotating cylinder 440 drives the material transfer claw cylinder 450 to rotate 180°, so that the motor gear box in the material transfer claw cylinder 450 will also rotate 180°, and then, under the mutual cooperation of the drive of the material transfer longitudinal device and the material transfer vertical drive device 430, the motor gear box in the material transfer claw cylinder 450 is placed in the fixture plate 200 on the conveyor belt 300, thereby completing the overall material transfer action of the material transfer component 400 of the present invention, and the driving mode of the material transfer longitudinal drive device 420 and the material transfer vertical drive device 430 can both be the driving mode of the cylinder.

[0057] In this embodiment, the present invention also provides an operating method of a worm gear virtual position measuring machine, comprising the following steps: S1, loading the motor gear box seat, the material transfer component 400 clamps the motor gear box seat and transfers it to the jig disk 200 on the conveyor belt 300; S2, the worm rotates, the conveyor belt 300 drives the jig disk 200 to move, and when the jig disk 200 passes through the worm rotation component 500, the worm rotation component 500 rotates and loosens the worm in the motor gear box seat in the jig disk 200; S3, measuring the virtual position, the conveyor belt 300 continues to drive the jig disk 200 to move, and when the jig disk 200 passes through the virtual position detection component 600, the virtual position detection component 600 measures the virtual position of the worm in the motor gear box seat in the jig disk 200.
