[0017] 1. In the present invention, the lifting column senses in real time that the transformer parts are pushed into the loading.

[0019] 3. In the present invention, the autonomous pushing component can control the loading and unloading of parts in the feed tray according to the rotation processing progress of the feed tray. When the feed tray rotates, the power component drives the rotating arm to rotate back and forth. The reciprocating rotation of the rotating arm corresponds to the feed conveyor rack and the processing groove corresponding to the discharge conveyor rack. The pushing cylinder on the running rotating arm controls the movement of parts in the feed conveyor rack and the processing groove through the pushing plate, which can realize the control of loading and unloading of parts according to the rotation processing progress of the feed tray, which is beneficial to the autonomous and continuous control of production of the automatic tapping machine.

DETAILED DESCRIPTION

[0034] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] See also Figures 1-6 As shown, an automatic tapping machine for the production of transformer parts includes a workbench 11 and a tapping machine body 12 installed on the workbench 11 by a hydraulic rod and capable of tapping transformer parts. The automatic tapping machine also includes a feeding conveyor rack 13 installed next to the workbench 11 for inputting transformer parts, a discharging conveyor rack 14 installed next to the workbench 11 for outputting transformer parts, and a feeding tray 2 rotatably installed on the workbench 11 for continuously tapping transformer parts; the feeding tray 2 is provided with processing grooves 31 for tapping transformer parts at equal intervals along its own circumferential direction, and each processing groove 31 is provided with a lifting column 32 that can contact the bottom of the transformer part. The feeding tray 2 is also provided with a clamping assembly 4 for correcting the transformer part to be centrally arranged in the processing groove 31.

[0036] The transformer components are input and output from the feed tray 2 through the feed conveyor rack 13 and the discharge conveyor rack 14, and the components are pushed into the processing groove 31 on the feed tray 2 corresponding to the position of the feed conveyor rack 13. The components squeeze the inclined surface of the lifting column 32 to move the lifting column 32 downward, and the lifting column 32 moves to drive the clamping assembly 4 to move. The clamping assembly 4 corrects and positions the components in the processing groove 31 so that the axis of the hole for tapping the component is in a collinear state with the axis of the tap of the tapping machine body 12, thereby maintaining the accuracy of the component processing position and controlling the intermittent rotation of the feed tray 2 so that the components in the different processing grooves 31 opened on the circumference rotate to correspond to the bottom of the tap of the tapping machine body 12, and the tapping process is continuously performed to improve production efficiency.

[0037] See also Figure 3-Figure 8 As shown, a guide groove 33 is provided in the lifting column 32 along its own axis, and a guide column 34 is provided in the feed tray 2. The lifting column 32 is slidably sleeved on the guide column 34 through the guide groove 33. A reset spring 35 is connected to the lifting column 32 and the bottom of the feed tray 2; the top of the lifting column 32 is formed with an inclined surface.

[0038] When the inclined surface of the lifting column 32 is pushed and squeezed by the component, the lifting column 32 is sleeved on the guide column 34 and moves downward to compress the return spring 35. When the component completely enters the processing groove 31, the upper surface of the lifting column 32 remains flush with the bottom surface of the processing groove 31, and the upper inclined surface of the lifting column 32 does not interfere with the tapping processing inside the component.

[0039] See also Figure 3-Figure 8 As shown, a limit slot 36 is provided on the guide column 34, and a blind slot is symmetrically provided at the deepest part of the guide slot 33. A horizontal positioning slide 37 is provided in the blind slot. One end of the positioning slide 37 is fixed in the blind slot, and the other end of the positioning slide is movably sleeved with a limit column 38 that can be engaged with the limit slot 36. A limit spring 39 is sleeved on the outside of the positioning slide 37, and the two ends of the limit spring 39 are respectively connected to the inside of the blind slot and one end of the positioning slide 37.

[0040] When the lifting column 32 moves down to the maximum position, the limit clamping columns 38 on both sides thereof move laterally under the elastic thrust of the limit spring 39, and the limit clamping columns 38 move and engage into the limit clamping groove 36. The lifting column 32 and the guide column 34 are engaged and limited by the engaging structure, thereby maintaining the moving position of the lifting column 32 at this time.

[0041] See also Figure 3-Figure 5 and Figure 8 As shown, an ejection cylinder 321 is fixedly installed on the workbench 11, and an ejection ring 322 is fixedly connected to the lifting end of the ejection cylinder 321. Ejection grooves 323 are arranged at equal intervals along the circumferential direction of the bottom of the feed tray 2. The ejection ring 322 and the ejection grooves 323 are distributed correspondingly up and down, and the ejection ring 322 corresponds to the position directly below the lifting column 32.

[0042] When the processing tank 31 rotates to correspond to the entrance of the discharge conveyor rack 14, the ejection cylinder 321 is operated to push the ejection ring 322 upward, the ejection ring 322 enters the ejection tank 323, and pushes the upper lifting column 32 upward. Under the action of the thrust, the lifting column 32 moves upward to release the engagement relationship with the guide column 34. The lifting column 32 moves upward to push the upper parts to the outside of the processing tank 31, and the processing waste chips on the inclined surface of the lifting column 32 are pushed upward. The processing waste chips in the processing tank 31 are cleaned under the action of the air pressure of the air injection pipe 25.

[0043] See also Figure 3-Figure 7As shown, the clamping assembly 4 includes a mobile frame 41 slidably mounted in the feed tray 2 , a clamping rod 42 is fixedly mounted on the mobile frame 41 , an adjusting rod 43 is rotatably connected to the mobile frame 41 , and the adjusting rod 43 is rotatably connected to the lifting column 32 .

[0044] When the lifting column 32 moves downward, the adjusting rod 43 connected between the moving frame 41 and the lifting column 32 rotates, and the rotating adjusting rod 43 drives the moving frame 41 and the clamping rod 42 to move toward the direction close to the component, so that multiple groups of clamping rods 42 synchronously approach and push the component to correct the position of the component in the processing groove 31.

[0045] See also Figure 1-Figure 3 As shown, a motor 21 is fixedly installed on the workbench 11, and a driving gear 22 is connected to the output end of the motor 21. A driven gear 23 is meshed next to the driving gear 22, and a driving column 24 is coaxially fixedly connected to the driven gear 23. The driving column 24 is fixedly connected to the feed tray 2; an air jet 25 is axially passed through the driving column 24 and the feed tray 2, and the air jet direction of the air jet 25 corresponds to the direction of the discharge conveyor rack 14, and the air jet 25 is fixedly connected to the workbench 11.

[0046] The running motor 21 controls the driving gear 22 to rotate, and drives the driven gear 23 to rotate under the action of meshing transmission. The driven gear 23 drives the driving column 24 and the feed tray 2 to rotate synchronously, so that the processing grooves 31 at different positions on the feed tray 2 rotate in sequence to correspond to the bottom of the tapping machine body 12.

[0047] See also Figure 1 、 Figure 2 and Figures 9-12 As shown, the feed conveyor rack 13 and the discharge conveyor rack 14 are provided with autonomous pushing components 5 for pushing transformer components into and out of the processing tank 31 .

[0048] The autonomous pushing assembly 5 pushes the parts on the feed conveyor rack 13 into the processing groove 31 on the feed tray 2 , and the autonomous pushing assembly 5 pushes the tapped parts in the processing groove 31 on the feed tray 2 onto the discharge conveyor rack 14 .

[0049] See also Figures 9-12 As shown, the autonomous pushing assembly 5 includes a rotating arm 51 rotatably mounted on the feed conveyor frame 13 and the discharge conveyor frame 14 , a pushing cylinder 52 is fixedly mounted on the rotating arm 51 , and a pushing plate 53 is fixed to the telescopic end of the pushing cylinder 52 .

[0050] When the feed tray 2 rotates to feed, the rotating arm 51 rotates back and forth once, keeping the feed tray 2 rotating and feeding normally and the feed conveyor rack 13 conveying parts normally. The rotating arm 51 on the feed conveyor rack 13 rotates correspondingly above the feed conveyor rack 13, and the pushing cylinder 52 is operated to push the pushing plate 53 to move, and push the parts on the feed conveyor rack 13 into the processing groove 31. The rotating arm 51 on the discharge conveyor rack 14 rotates correspondingly above the feed tray 2, and the pushing cylinder 52 is operated to push the pushing plate 53 to move, and push the parts in the processing groove 31 to the discharge conveyor rack 14, autonomously controlling the processing of parts in and out.

[0051] See also Figure 10-12 As shown, a power assembly 6 for controlling the reciprocating rotation of the rotating arm 51 is provided on the workbench 11 .

[0052] The power assembly 6 controls the rotation of the rotating arm 51 according to the rotation processing progress of the feeding tray 2.

[0053] See also Figure 10-12 As shown, the power assembly 6 includes a transmission gear 61 rotatably mounted on the workbench 11 and meshing with the driven gear 23, a turntable 62 is coaxially fixed on the transmission gear 61, a sliding column 63 is eccentrically fixed on the turntable 62, a guide support frame 64 is fixedly mounted on the workbench 11, a slide frame 65 is slidably mounted in the guide support frame 64, the sliding column 63 slides with the slide frame 65, a rack 66 is fixedly mounted on the slide frame 65, and an axial fixed sleeve of the rotating arm 51 is provided with a rotating gear 67, which is meshed with the rack 66.

[0054] When the feed tray 2 rotates, the driven gear 23 below drives the transmission gear 61 to rotate through meshing transmission, and the turntable 62 below the transmission gear 61 rotates synchronously. The sliding column 63 on the turntable 62 is engaged and slides in the slide frame 65. The sliding structure of the synchronous sliding column 63 and the slide frame 65 cooperates to control the slide frame 65 to move back and forth through the guide support frame 64. The rack 66 fixedly connected to the slide frame 65 moves back and forth synchronously, and the rotating gear 67 is driven to rotate back and forth through meshing transmission, thereby achieving the purpose of driving the rotating arm 51 to rotate back and forth.

[0055] Working principle: The transformer parts are placed on the feed conveyor rack 13 and transported to the feed tray 2. The parts on the feed conveyor rack 13 are pushed into the processing groove 31 opened on the feed tray 2 through the independent pushing component 5. When the parts enter the processing groove 31, they contact the upper inclined surface of the lifting column 32. The inclined surface of the lifting column 32 moves downward under the squeezing effect of the pushed parts. The lifting column 32 moves downward to compress the return spring 35. When the parts are completely moved into the processing groove 31, the plane of the upper surface of the lifting column 32 is flush with the bottom of the processing groove 31. The limit card column 38 in the lifting column 32 moves to the horizontal position of the limit card groove 36 opened on the side of the guide column 34. The limit card column 38 is engaged into the limit position under the elastic thrust of the limit spring 39. In the slot 36, the engaging direction is perpendicular to the moving direction of the lifting column 32. The engaging structure of the limit clamping column 38 and the limit clamping slot 36 can quickly limit the moving position of the lifting column 32, and when the lifting column 32 moves downward, the two ends of the adjusting rod 43 connected between the lifting column 32 and the moving frame 41 rotate accordingly, and the adjusting rod 43 pushes the moving frame 41 and the clamping rod 42 to move laterally. Multiple clamping rods 42 move synchronously in the direction close to the parts in the processing groove 31. Under the thrust of the clamping rod 42, the parts can be centered and stably set in the processing groove 31, keeping the axis of the hole processed by the parts and the axis of the tapping machine body 12 in a collinear position, improving the processing accuracy of the parts, and keeping the taps of the tapping machine body 12 evenly stressed during tapping.

[0056] After the parts are confined inside the processing groove 31 in the feed tray 2, the running motor 21 controls the driving gear 22 to rotate, and the driving gear 22 drives the driven gear 23 to rotate through meshing transmission. The driving column 24 coaxially fixed on the driven gear 23 and the feed tray 2 rotate synchronously. The feed tray 2 rotates intermittently so that the circumferentially distributed processing grooves 31 rotate in turn to correspond to the bottom of the tapping machine body 12, controlling the tapping machine body 12 to move downward, and the tap on the tapping machine body 12 rotates into the hole of the part to complete the tapping process.

[0057] The processed parts rotate along the feed tray 2 to the direction corresponding to the discharge conveyor rack 14, and the ejection cylinder 321 is operated to push the ejection ring 322 upward. The ejection ring 322 passes through the ejection groove 323 and contacts the bottom surface of the lifting column 32. The lifting column 32 is separated from the guide column 34 under the action of the thrust, and the lifting column 32 moves upward to push the parts to the outside of the processing groove 31. The lifting column 32 pushes the processing waste accumulated on the inclined surface upward, and the processing waste in the processing groove 31 is cleaned under the action of the air jet 25. The autonomous pushing component 5 pushes the parts in the processing groove 31 to the discharge conveyor rack 14.

[0058] When the feed tray 2 rotates, the driven gear 23 below controls the rotation of the transmission gear 61 in the two groups of power components 6 through meshing transmission, and the turntable 62 fixed on the transmission gear 61 rotates synchronously. The sliding column 63 on the turntable 62 rotates in a circle to push the slide frame 65 to move back and forth. The slide frame 65 runs through the guide support frame 64 and drives the rack 66 to move back and forth synchronously. The rack 66 drives the rotating gear 67 to rotate back and forth through meshing transmission, so that the rotating arm 51 is controlled to rotate back and forth when the feed tray 2 rotates to feed, so that the autonomous pushing component 5 can control the parts to and from the feed tray 2 according to the rotation feeding progress of the feed tray 2.

[0059] The above embodiments merely represent one or more embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
