Description

Technical Field

[0001] The present invention relates to the technical field of transformer terminal machining, in particular to transformer component machining equipment. Background Art

[0002] Transformer is a key equipment for realizing voltage conversion in power system and is widely used in power transmission and distribution system. It is mainly composed of multiple components such as iron core, winding, oil tank, terminal, protective device, etc. These components work together to ensure that the transformer can convert and transmit electric energy safely and stably. Among them, the terminal is an important component of the transformer. It is the electrical contact point connecting the transformer with the external circuit. Its main function is to undertake the current transmission between the power line and the transformer winding to ensure that the current can flow losslessly and stably. The terminal is usually made of metal material with good conductivity, corrosion resistance and mechanical strength; the transformer terminal is mainly composed of a rectangular metal plate and a terminal ear plate fixedly connected to the metal plate. The metal plate provides support and fixing functions, connects other parts of the transformer, and ensures the stability of the terminal during transformer operation. The ear plate part is usually used to connect cables or terminal blocks, and is fixed by bolts and other methods to ensure the reliability of the electrical connection.

[0003] In the processing of transformer terminals, multiple machining operations are involved, such as drilling, cutting, and drilling at different positions during the processing of terminal plates and terminal ear plates (the shape of the transformer terminal blank before processing is as follows: Figure 8 The terminal lugs also need to be slit so that the cables or connectors can be inserted and firmly fixed. During the terminal processing, due to the different hole positions of the opening and the slit, frequent direction changes are required during processing. Specifically: Drilling direction: Drilling usually needs to be done on the terminal plate and the lug, and the position and direction of the holes are different; Slit cutting direction: The slit on the lug needs to be cut in a direction perpendicular to the hole direction on the terminal metal plate.

[0004] Due to the different directions of these holes and slits, the terminals need to be removed from the fixture during processing and re-clamped for processing in different directions. Each time the fixture direction is adjusted, it takes time to operate, which increases the number of manual changes and clamping in the production process, and also increases errors and instability during operation. Summary of the Invention

DETAILED DESCRIPTION

[0030] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] See also Figure 1 and Figure 3The present invention provides a technical solution: a transformer component machining equipment, comprising a plurality of laterally equidistantly distributed support platforms 1, the upper end surfaces of the support platforms 1 are fixedly connected to a rectangular frame seat 2, two rail grooves 3 are symmetrically provided on the upper end surface of the rectangular frame seat 2, a strip-type electric slide 4 is slidably connected in the rail groove 3, a plurality of discharge holes 10 are equidistantly provided at the bottom of the rail groove 3, and an inclined shovel plate 11 is fixedly connected to the left and right sides of the strip-type electric slide 4. When the strip-type electric slide 4 moves laterally during the processing of the transformer terminal, the inclined shovel plate 11 moves synchronously. The inclined shovel plate 11 moves and pushes the metal chips that fall into the rail groove 3 during the processing into the discharge holes 10 passed through for discharge, so as to prevent the metal chips in the rail groove 3 from affecting the movement of the strip-type electric slide 4. A drilling mechanism 5 is provided on the right part of the upper end surface of the rectangular frame seat 2, and a cutting part 6 is provided on the left part of the upper end surface of the rectangular frame seat 2. Several strip-type electric slides are equidistantly provided between the two strip-type electric slides. The adjusting mechanism 7 is provided with a self-clamping mechanism 8 for clamping and limiting the transformer terminals. The inner cavity of the rectangular frame seat 2 is provided with a matching mechanism 9. When the strip-type electric slide 4 drives the self-clamping mechanism 8 for clamping the transformer terminals to move intermittently horizontally, the matching mechanism 9 is triggered to cooperate with the adjusting mechanism 7 to automatically adjust the position of the transformer terminals, so that the transformer terminals can be automatically punched and opened by the drilling mechanism 5 and the cutting part 6 in turn. The drilling mechanism 5 includes a door frame 51 fixedly connected to the upper end face of the rectangular frame seat 2, and the lower end face of the transverse section of the door frame 51 is fixedly connected to an electric telescopic rod 52. The lower end of the electric telescopic rod 52 is fixedly connected to a mounting plate 53. A No. 1 electric drill group 54 is provided on the right part of the lower end face of the mounting plate 53, and a No. 2 electric drill group 55 is provided on the left part of the lower end face of the mounting plate 53. The cutting part 6 includes a door frame 61 fixedly connected to the upper end face of the rectangular frame seat 2, and a cutting machine 62 is fixedly connected to the transverse section of the door frame 61.

[0032] See also Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7In this embodiment, the self-clamping mechanism 8 includes a support shaft 81 rotatably connected to the upper end surface of the base 73, the upper end surface of the support shaft 81 is fixedly connected to a support 82, the support 82 is provided with a chip receiving groove 83, the support 82 is provided with a slide group symmetrically provided on the left and right sides, and a slide frame 84 is slidably connected to the slide group. The slide frame 84 is composed of a T-shaped rod and two vertical columns symmetrically fixedly connected to the upper end surface of the long section of the T-shaped rod. The upper part of the slide frame 84 is fixedly connected to a clamping plate 85, and the lower end surface of the slide frame 84 is fixedly connected to a push rod. The column 86, the push column 86 and the support shaft 81 are fixedly connected with a return spring. The upper end surface of the base 73 is fixedly connected to two arc-shaped plates 87 for cooperating with the push column 86 through a fixed block. An auxiliary limiting mechanism 88 is provided between the two splints 85 and the support 82. The outside of the support shaft 81 is fixedly connected with a gear disk 89. The rear part of the right cavity wall and the front part of the left cavity wall of the rectangular frame seat 2 are fixedly connected with a rack 810 cooperating with the gear disk 89 through a support bar, that is, the two racks 810 are symmetrically distributed in the center.

[0033] See also Figure 5 The auxiliary limiting mechanism 88 includes a sliding groove 881 provided on the upper end surface of the support 82, a sliding plate 882 slidingly connected to the sliding groove 881, and a plug column 883 fixedly connected to the upper end surface of the sliding plate 882. The upper part of the plug column 883 is provided with an embedding groove along its own axial direction. The front end surface of the splint 85 is fixedly connected to a push rod 884, and a connecting rod 885 is hinged between the push rod 884 and the sliding plate 882.

[0034] like Figure 1 The self-clamping mechanism 8 is shown in its initial state. The strip-type electric slide 4 is located at the rightmost position of the rectangular frame seat 2. Then, the transformer terminals are placed on the support 82 (the terminal ear plate faces the front) manually or by an external mechanical claw. Then, the strip-type electric slide 4 is controlled to move intermittently to the left. The strip-type electric slide 4 then drives the support shaft 81 and the support 82 to move intermittently to the left through the adjustment mechanism 7. The support shaft 81 then drives the gear plate 89 to move synchronously. When the gear plate 89 is driven to move to the left until it engages with the rack 810, the rack 810 on the right engages with the rear part of the gear plate 89, causing the gear plate 89 to start rotating counterclockwise until it rotates ninety degrees. The gear plate 89 Separated from the rack 810, during this process, the gear disc 89 drives the support 82 to rotate through the support shaft 81, and the support 82 then drives the push column 86 to rotate ninety degrees around the support shaft 81 through the sliding frame 84. During the revolution of the push column 86, it will first hit the front and rear opposite inclined surfaces of the arc plate 87, and move toward the axis of the arc plate 87 under the pressure of the inclined surface of the arc plate 87. The push column 86 then drives the clamping plate 85 to move toward the axis of the arc plate 87 through the sliding frame 84, so that the two clamping plates 85 move close to each other and touch the left and right sides of the transformer terminal, clamping the transformer terminal. At this time, the push column 86 rotates until it hits the arc-shaped inner wall of the arc plate 87.

[0035] The two clamping plates 85 move toward each other and at the same time drive the push rod 884 to move. The push rod 884 then presses the sliding plate 882 through the connecting rod 885 to move toward the axis of the support shaft 81. The sliding plate 882 then drives the plug post 883 to move, so that the plug post 883 is inserted into the wire hole at the ear plate when the transformer terminal is in the blank state. In this way, the wire hole on the transformer terminal can be used as a fixed point to further limit the transformer terminal while clamping, thereby enhancing the stability of the transformer terminal when clamping.

[0036] The strip-shaped electric slide 4 drives the clamped transformer terminal to move intermittently to the left and stops when passing under the No. 1 electric drill group 54, the No. 2 electric drill group 55 and the cutting machine 62 in turn, drilling holes in the metal plate and the ear plate in the transformer terminal and making slits on the ear plate. When the transformer terminal plate is machined and moves to the left to the position of the rack 810 on the left, the front part of the gear disc 89 engages with the rack 810 on the left, and then the gear disc 89 rotates clockwise. During the clockwise rotation of the gear disc 89, the support shaft 81 will be driven to rotate synchronously, and the support shaft 81 then drives the support 82 to rotate, and the support 82 is driven by the sliding frame 84 to push the support 82. The column 86 rotates, causing the push column 86 to move from the position where it touches the curved inner wall of the curved plate 87 to the position between the two curved plates 87. The reset spring resets and pushes the two push columns 86 to move away from each other. The push column 86 then drives the clamping plate 85 to move through the sliding frame 84, so that the clamping plate 85 and the transformer terminal are released. The two clamping plates 85 move away from each other and at the same time drive the connecting rod 885 to move through the push rod 884. The connecting rod 885 then drives the plug column 883 to move out of the transformer terminal through the sliding plate 882, thereby facilitating the removal of the processed transformer terminal. At this time, the self-clamping mechanism 8 moved to the left has returned to its initial state.

[0037] Then the next batch of transformer terminals can be placed in the self-clamping mechanism 8 which has moved to the left at this time, and then the above steps are repeated in reverse to control the strip-type electric slide 4 to move intermittently to the right. The strip-type electric slide 4 then drives the self-clamping mechanism 8 to move intermittently to the right, and repeat the above steps of automatically clamping the transformer terminals. Then, they are processed under the cutting machine 62, the No. 2 electric drill group 55 and the No. 1 electric drill group 54 in sequence, and finally moved until the gear disc 89 is engaged with the rack 810 on the right, indirectly driving the clamping plate 85 to loosen the transformer terminals.

[0038] See also Figure 2 、 Figure 3 、 Figure 4 and Figure 5In this embodiment, the direction adjustment mechanism 7 includes a rectangular mounting frame 71 fixedly connected between the two bar-type electric slides 4, a base 73 rotatably set on the rectangular mounting frame 71 through a coupling assembly 72, and a counterweight bar 74 fixedly connected to the front end surface of the base 73. The coupling assembly 72 includes a load-bearing shaft 721 rotatably connected between the left and right opposite sides of the rectangular mounting frame 71, the base 73 is fixedly connected to the outside of the load-bearing shaft 721, and a limiting member 722 for limiting the rotation stroke of the load-bearing shaft 721 is jointly provided between the load-bearing shaft 721 and the rectangular mounting frame 71. The limiting member 722 includes an arcuate groove 7221 opened on the left and right opposite sides of the rectangular mounting frame 71 and a sliding column 7222 fixedly connected to the outside of the load-bearing shaft 721 through a connecting block and slidably set in the arcuate groove 7221.

[0039] See also Figure 2 、 Figure 3 and Figure 4 The matching mechanism 9 includes a special-shaped support rod 91. The special-shaped support rods 91 located below the base 73 are fixedly connected to the left and right opposite sides of the rectangular frame seat 2. The front surface of the lower end of the base 73 abuts against the upper side of the special-shaped support rod 91. The area between the two special-shaped support rods 91 is located directly below the No. 2 electric drill group 55. The special-shaped support rod 91 is used to support the base 73 or make it suspend in the air to flip and adjust its position. The special-shaped support rod 91 consists of a transverse section and an inclined section fixedly connected to one end of the transverse section close to each other. A transverse plate is fixedly connected between the left and right opposite sides of the rectangular frame seat 2, and a number of reinforcing columns 92 are fixedly connected equidistantly between the transverse plate and the transverse section of the special-shaped support rod 91.

[0040] When the self-clamping mechanism 8 clamps the transformer terminal and moves to the left, the base 73 is in contact with the transverse section of the special-shaped support rod 91 and is in a horizontal state. At this time, the sliding column 7222 is located at the upper position of the arc-shaped groove 7221, so the base 73 is in a stuck state (unable to rotate). When the strip-shaped electric slide 4 drives the transformer terminal clamped by the self-clamping mechanism 8 to move intermittently to the left to the bottom of the No. 1 electric drill group 54, it will pause, and then control the electric telescopic rod 52 to extend and drive the mounting plate 53 to move downward. The mounting plate 53 then drives the No. 1 electric drill group 54 and the No. 2 electric drill group 55 to move downward at the same time. When the No. 1 electric drill group 54 moves down to contact the rectangular metal plate in the transformer terminal, it will drill a hole in it. After drilling, the electric telescopic rod 52 begins to contract and indirectly drives the No. 1 electric drill group 54 to move upward.

[0041] The base 73 rotates to a vertical position, and the base 73 drives the transformer terminal clamped by the self-clamping mechanism 8 to flip forward 90 degrees around the axis of the bearing shaft 721. At this time, the ear plate in the flipped transformer terminal is located directly under the No. 2 electric drill group 55.

[0042] Then the electric telescopic rod 52 extends again to drive the mounting plate 53 to move downward, and the mounting plate 53 drives the No. 2 electric drill group 55 to move downward and contact the transformer terminal ear plate, and drills the transformer terminal ear plate. After the No. 2 electric drill group 55 drills through the transformer terminal ear plate, the electric telescopic rod 52 will shrink again to drive the mounting plate 53 to move upward, and the mounting plate 53 drives the No. 2 electric drill group 55 to move upward, and then the strip-type electric slide 4 starts to move to the left again, and the strip-type electric slide 4 drives the base 73 to move left through the rectangular mounting frame 71. During the process of moving left, the base 73 will contact the inclined section of the special-shaped support rod 91 on the left, and then it will be squeezed by the inclined section of the special-shaped support rod 91 on the left and rotate forward around the axis of the load-bearing shaft 721 until the base 73 rotates to contact the horizontal section of the special-shaped support rod 91 on the left.

[0043] At this time, the base 73 becomes horizontal again, and the base 73 indirectly drives the transformer terminal to return to a horizontally lying state. Then the strip-type electric slide 4 drives the transformer terminal with the terminal ear plate drilled to move left again, passing under the cutting machine 62. The cutting machine 62 performs a slit on the transformer terminal ear plate. During the slitting process, the saw blade of the cutting machine 62 will also extend into the embedded groove of the plug column 883 to ensure that the cutting machine 62 can cut through the terminal ear plate. After the slitting is completed, the transformer terminal is driven by the self-clamping mechanism 8 to move left to the position of the rack 810 on the left, so that the toothed disc 89 engages with the rack 810 on the left, thereby indirectly driving the clamping plate 85 to loosen the transformer terminal.

[0044] When the strip-shaped electric slide 4 starts to move intermittently from left to right, the above steps are repeated. When the rectangular mounting frame 71 moves between the two special-shaped support rods 91, the base 73 will repeat the above steps and flip around the axis of the bearing shaft 721 to automatically adjust the direction of the transformer terminal.

[0045] During operation, first move the strip-type electric slide 4 to the right of the rectangular frame seat 2, then place the transformer terminal on the self-clamping mechanism 8, and then control the strip-type electric slide 4 to drive the adjustment mechanism 7 and the self-clamping mechanism 8 to move intermittently to the left. During the movement of the self-clamping mechanism 8 to the left, it is triggered to automatically clamp the transformer terminal and adjust the transformer terminal to a horizontal state. Then, when the transformer terminal moves, the drilling mechanism 5 is controlled to operate when the No. 1 electric drill group 54 in the drilling mechanism 5 is directly below to drill the transformer terminal metal plate. After drilling, the transformer terminal is caught and moved to the left for a distance, and the transformer terminal is moved to the left. During the process of moving to the bottom of the No. 2 electric drill group 55, the direction adjustment mechanism 7 cooperates with the matching mechanism 9 to automatically flip the transformer terminal, and then the drilling mechanism 5 drives the No. 2 electric drill group 55 to drill the transformer terminal ear plate. After the terminal ear plate is drilled, the strip-type electric slide 4 drives the transformer terminal to move to the left again, so that the terminal ear plate passes under the cutting machine 62, and the terminal ear plate can be slit. Then, the self-clamping mechanism 8 is triggered again to release the transformer terminal, and the transformer terminal can be removed. Finally, the strip-type electric slide 4 is controlled again to move intermittently from left to right, and the above steps are performed again.
