Description

Technical Field

[0001] The present invention relates to the technical field of transformer component processing equipment, in particular to transformer insulation pressing plate processing equipment. Background Art

[0002] After the winding of the current transformer three-dimensional wound core is completed, a pressure plate needs to be set on the winding to press the edge of the winding, and at the same time, the pressure plate is used to achieve insulation between the edge of the winding and the core. The current pressure plate generally has an oil groove for oil passing on one side; the current processing method of this pressure plate is mainly through manual processing, that is, marking on the triangular pressure plate, and using a planer to open multiple oil grooves on the triangular pressure plate. Pillow blocks need to be left between the oil grooves, and the pillow blocks are used to press on the winding; the above-mentioned manual processing method results in a low processing efficiency of the triangular pressure block, which cannot meet the needs of large quantities of three-dimensional wound cores. At the same time, the work intensity of the staff is relatively high when manually opening the oil grooves on the triangular pressure plate. For this reason, Chinese patent publication number CN118197768A proposes an automated processing equipment for insulating pressure plates of closed-end wound core transformers, including a pressure plate conveying mechanism, a pressure plate clamping mechanism, an oil channel slotting mechanism and an adjustment mechanism. A pressure plate conveying mechanism is provided on the ground, a plurality of positioning components for positioning the triangular pressure plates are provided on the pressure plate conveying mechanism, a pressure plate clamping mechanism is provided on one side of the pressure plate conveying mechanism, a transfer component is provided between the pressure plate clamping mechanism and the pressure plate conveying mechanism, a rotating component is provided below the pressure plate clamping mechanism, and an oil channel slotting mechanism is provided above the pressure plate clamping mechanism; the equipment facilitates the automated processing of the triangular pressure plates, reduces labor intensity, and improves the processing efficiency of the triangular pressure plates; The more obvious disadvantage of the above-mentioned public technology is that its processing equipment cannot perform drilling processing on the triangular pressure plate, and additional equipment is required for drilling processing, resulting in secondary clamping. First, it increases labor intensity, and second, there is an error in the position accuracy between the hole and the groove. Moreover, the device is cumbersome when clamping and positioning the triangular pressure plate, and the structure is too complicated to be conducive to promotion and use.

[0003] In summary, it is necessary to optimize and improve the structure of transformer insulation plate processing equipment to improve the degree of automation during transformer insulation plate processing and reduce labor intensity. Summary of the Invention

By providing a drilling device and three sets of milling devices, in conjunction with the intermittent movement of the annular guide rail conveying device, the drilling processing of multiple sets of through holes 1101 and the milling processing of three sets of grooves 1102 are completed, and all processing can be completed in one clamping; The dust suction device forms negative pressure on the drilling or milling area through the outer dust suction pipe 5 and the inner dust suction pipe 17 to suck away the debris and powder generated during the processing; when the circular guide rail conveying device drives the substrate 7 to move from the first milling process to the second milling process, one set of reversing levers 14 is blocked by the block 602, so that the turntable 8 rotates when the substrate 7 moves backward, until the fixed sleeve 13 completely passes through the block 602, and the first cylinder 6 extends the shaft to push the reversing lever 14 in contact with the block 602, so that the axis of the reversing lever 14 is parallel to the front and rear direction of the machine 1. At this time, the turntable 8 is rotated 120 degrees and pushed in sequence by the two sets of first cylinders 6. The turntable 8 is able to rotate twice, thereby cooperating with the three sets of milling devices to complete the milling of the three sets of grooves 1102; the area formed between the three sets of positioning blocks 10 is used to locate the front, back, left and right positions of the insulating pressure plate body 11, and the material moving robot clamps the unprocessed insulating pressure plate body 11 and puts it between the three sets of positioning blocks 10 to complete the positioning; when drilling or milling, the second cylinder 15 extends the shaft to drive the top block 16 to rise until it supports the lower wall of the substrate 7. At this time, drilling or milling will not cause the substrate 7 to sink; when the insulating pressure plate body 11 moves to the bottom of the drilling device, the third cylinder 29 drives the first mounting platform 18 to move downward until the first pressing head 21 presses the insulating pressure plate body 11. The insulating pressure plate body 11 is then started, and multiple sets of drilling motors are started to drive multiple sets of drill bits 22 to rotate, and then the shaft is extended through the fourth cylinder 30 to drive the first inner box and multiple sets of rotating drill bits 22 to move downward, and the drill bits 22 are used to drill the insulating pressure plate body 11 to form a through hole 1101. Multiple sets of drill bits 22 can be synchronously driven by a common drilling motor through a gear set, or can be driven separately by multiple sets of drilling motors, both of which are existing technologies on the market. In this embodiment, each drill bit 22 is equipped with a drilling motor, and the avoidance hole 801 is to prevent the drill bit 22 from drilling into the turntable 8; after the insulating pressure plate body 11 is drilled out of the through hole 1101 by the drilling device, it moves to the bottom of the milling device On the other hand, the fifth cylinder 32 drives the second mounting platform 23 to descend until the second pressing head 26 presses the insulating pressure plate body 11, and then the slot milling motor is started to drive the slot milling cutter 28 to rotate, and the sixth cylinder 33 drives the second inner box to descend, so that the slot milling cutter 28 is inserted into a group of through holes 1101 in the center of the upper wall of the insulating pressure plate body 11, and then the slot milling cutter 28 is driven forward by translation, and the groove 1102 is milled out by the rotating slot milling cutter 28. The inner wall of the second mounting platform 23 is provided with a vertically through-going avoidance groove 27, and the slot milling cutter 28 passes through the inside of the avoidance groove 27. The length direction of the avoidance groove 27 is distributed front to back, and the avoidance groove 27 is used for avoiding the slot milling cutter 28 when it moves;When drilling, the first mounting platform 18 descends, driving the three sets of first positioning rods 20 downward. These rods are inserted into the inner sidewalls of a set of positioning holes 9, thereby positioning the turntable 8 during drilling. When milling, the second mounting platform 23 descends, driving the three sets of second positioning rods 25 downward. These rods are inserted into the inner sidewalls of a set of positioning holes 9, thereby positioning the turntable 8 during milling. Before drilling and milling, the insulating pressure plate body 11 is pressed from above by the first and second pressing heads 21 and 26, respectively, to prevent vibration during processing.
