Description

Technical Field

[0001] The invention relates to the technical field of drilling equipment, in particular to a drilling device for processing dry-type transformer components. Background Art

[0002] The iron core in a dry-type transformer is one of the most important components. The iron core is usually made of silicon steel sheets. During the manufacturing process of the iron core silicon steel sheets of the dry-type transformer, the silicon steel sheets usually need to be drilled. The drilled circular holes can not only be used to fix the upper and lower clamps, but also have the functions of reducing eddy current loss, ventilation and heat dissipation, and reducing iron loss. The iron core in a dry-type transformer is usually composed of multiple E-type silicon steel sheets and I-type silicon steel sheets stacked together, as shown in the attached figure. Fig.13 As shown. However, there are certain problems in the existing silicon steel sheet drilling process: during the drilling process, it is necessary to drill holes for E-type silicon steel sheets and I-type silicon steel sheets respectively. The clamping positions required for E-type silicon steel sheets and I-type silicon steel sheets during drilling are different, so different block clamps need to be designed for different types of silicon steel sheets, which increases the cost of the equipment; during continuous drilling, automatic loading is required, but in the existing equipment, the automatic loading mechanism requires an independent driving source for loading, the driving source of the equipment increases, and the existing equipment usually uses the conveyor chain for loading.

[0037] During use of the pressing mechanism 3, the driving motor 311 is first turned on, and the output end of the driving motor 311 starts to rotate, driving the active gear 312 to rotate, indirectly driving the driven gear 314 to rotate, and then driving the screw rod 317 to rotate. Since the screw rod 317 and the movable block 318 are connected by a ball nut, the movable block 318 is driven to move along the guide rail 316 to the designated crimping position on the silicon steel sheet. At this time, the output end of the No. 1 hydraulic cylinder 5 moves downward, and then drives the fixed frame 4 to move downward, and then drives the pressing mechanism 3 to move downward, and then drives the limiting angle iron 331 to move downward and squeeze onto the silicon steel sheet, and then pre-presses and positions the silicon steel sheet. When drilling is required, the output end of the No. 1 hydraulic cylinder 5 continues to extend until the pressing block 322 is tightly pressed onto the silicon steel sheet, and the E-type silicon steel sheet is crimped and fixed by the pressing block 322.

[0040] See also Figure 2 and Figure 7 The vacuum adsorption feeding mechanism 7 includes a linkage rod 71, which is installed between the two movable blocks 318.

[0041] During the use of the vacuum adsorption feeding mechanism 7, when the silicon steel sheet drilling is completed, the vacuum adsorption feeding mechanism 7 is used to feed the next silicon steel sheet. First, the output end of the No. 1 hydraulic cylinder 5 moves up, driving the fixed frame 4 to move up, and then drives the pressing mechanism 3 to move up, loosening the rigid pressing connection of the rigid pressing component 32 on the silicon steel sheet, and maintaining the pressing connection of the pre-pressing component 33 on the silicon steel sheet. At this time, the output end of the drive motor 311 is opened to drive the movable block 318 to move to the top of the next silicon steel sheet waiting for loading. At this time, the output end of the cylinder 74 extends out, driving the mounting plate 77 to move down, and then drives the vacuum suction cup 76 to move down until the vacuum suction cup 76 is adsorbed to the top of the silicon steel sheet. At this time, the vacuum pump 73 performs suction, which is beneficial to The silicon steel sheet is adsorbed by the vacuum suction cup 76. At this time, the output end of the driving motor 311 is reversed, driving the movable block 318 to move in the direction of the symmetrical drilling mechanism 6. The silicon steel sheet to be processed is used to extrude the processed silicon steel sheet, thereby realizing automatic loading and unloading of the silicon steel sheet. The movable block 318 and the screw rod 317 are connected by a ball nut, and the screw rod 317 is used for feeding to ensure the accuracy of loading. After loading to the specified position, the vacuum suction cup 76 releases the adsorption, and the vacuum adsorption feeding mechanism 7 is reset. At this time, the No. 1 hydraulic cylinder 5 continues to move downward and repeats the drilling operation. The vacuum adsorption feeding mechanism 7 is linked with the pressing mechanism 3, and there is no need to specially set a driving source to move the vacuum adsorption feeding mechanism 7.

[0042] See also Figure 2 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 The automatic locking mechanism 8 includes a telescopic active extrusion rod 81 and a mounting box 82. The telescopic active extrusion rod 81 is installed on the fixed connecting rod 34 on one side close to the center of the screw rod 317. The mounting box 82 is installed on the movable connecting rod 35 on one side close to the center of the screw rod 317. The interior of the mounting box 82 is hollow, and a reciprocating clamping assembly 83 is installed inside the mounting box 82. A locking assembly 84 is installed on the side of the reciprocating clamping assembly 83 close to the telescopic active extrusion rod 81. The reciprocating clamping assembly 83 includes a first hinge seat 832. The first hinge seat 832 is installed at the center of one side of the mounting box 82 away from the telescopic active extrusion rod 81. The clamping rod 833 is hinged on the first hinge seat 832 through a torsion spring. Two first return springs 831 are symmetrically installed on the side of the mounting box 82 away from the telescopic active extrusion rod 81, and a reciprocating block 834 is installed at one end of the two first return springs 831. The reciprocating block 834 is movably installed on the mounting Inside the box 82, a driven extrusion rod 85 is installed at the center of one side of the reciprocating block 834 close to the telescopic active extrusion rod 81, a clamping track groove 835 is eccentrically opened at the top of the reciprocating block 834, a clamping groove 836 is opened on the side of the clamping track groove 835 close to the driven extrusion rod 85, and the clamping rod 833 is movably installed inside the clamping track groove 835, and a limiting groove is opened at the center of the side of the driven extrusion rod 85 away from the reciprocating block 834, the reciprocating block 834 is symmetrically installed with two second hinged seats 844, and the two second hinged seats 844 are hinged with locking arms 841, the two locking arms 841 are installed with second return springs 845 at one end close to the second hinged seat 844, and the two second return springs 845 are installed with fixed blocks 843 at one end, the two fixed blocks 843 are symmetrically installed on one side of the reciprocating block 834 close to the driven extrusion rod 85, and the opposite side of the two locking arms 841 is installed with locking arc blocks 842.

[0043] When feeding, after the vacuum adsorption feeding mechanism 7 adsorbs the silicon steel sheet, the driving motor 311 in the pressing mechanism 3 is turned on, and the driving component 31 drives the movable block 318 to move in the direction of the first fixed plate 315. At this time, the telescopic active extrusion rod 81 squeezes the driven extrusion rod 85, and the limiting groove on the driven extrusion rod 85 is used to fit and limit the ball head of the telescopic active extrusion rod 81. As the extrusion drives the reciprocating block 834 to move in the direction of the first hinge seat 832, the first return spring 831 is compressed. At this time, the bottom of the clamping rod 833 moves along the clamping track groove 835 until the bottom of the clamping rod 833 is clamped into the inside of the clamping groove 836. When the reciprocating block 834 enters the interior of the installation box 82, the locking arm 841 is driven by the extrusion of the side wall of the installation box 82 to rotate around the second hinge seat 844, and then the locking arc block 842 is driven to move in the center. The active extrusion rod 81 is locked and fixed. When the telescopic active extrusion rod 81 is locked, the silicon steel sheet to be processed cannot move, ensuring that the pushing distance of the silicon steel sheet to be processed on the already processed silicon steel sheet is fixed, thereby ensuring the accuracy of drilling. When the loading is completed, the adsorption of the vacuum adsorption feeding mechanism 7 is released, and the output end of the No. 1 hydraulic cylinder 5 moves downward, driving the rigid pressing assembly 32 to press and fix the silicon steel sheet. When it is necessary to release the lock, under the drive of the driving assembly 31 in the pressing mechanism 3, the reciprocating block 834 continues to be squeezed in the direction of the first hinge seat 832. At this time, the clamping rod 833 disengages from the clamping groove 836 and continues to move along the clamping track groove 835 under the action of the torsion spring, and then the drive motor 311 is reversed to realize the separation movement of the two rigid pressing assemblies 32. The automatic locking mechanism 8 is linked with the pressing mechanism 3. There is no need to specially set up a driving source, and there is no need for manual locking and loosening, so the work efficiency is high. The telescopic active extrusion rod 81 is an existing telescopic rod, and its length can be adjusted according to actual needs to control the pushing distance of the silicon steel sheet to be processed on the silicon steel sheet that has been processed each time.
