Description

Technical Field

[0001] The utility model belongs to the technical field of transformer-related accessory processing, in particular to a transformer chamfering and compacting machine. Background Art

[0002] A transformer is an electrical device used to change AC voltage, and it uses the principle of electromagnetic induction to achieve conversion between input and output voltages. A transformer usually consists of an iron core and windings, where the iron core is made of laminated silicon steel sheets to reduce hysteresis loss and eddy current loss, and the windings include input windings and output windings. Transformers are widely used in various fields, such as power systems, industrial production, and household electricity. In power systems, transformers play the role of converting electrical energy on high-voltage transmission lines into low-voltage electrical energy suitable for users. In industrial production, transformers are used to adjust the voltage and current required by equipment to meet the electrical requirements of different equipment. In terms of household electricity, transformers are also often used to provide suitable voltages for household appliances.

[0003] The clearance pad inside the transformer is an important part of the transformer. The pad needs to be compacted and chamfered during the processing. Most of the existing processing equipment carries out this process in a distributed manner. The overall processing takes a long time, and it takes a long time to adjust the milling cutter position when the width of the processing pad changes. Moreover, the processing accuracy is prone to errors after adjustment. Utility Model Content

[0004] The utility model aims to provide a transformer chamfering and compacting machine to solve the problems existing in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A transformer chamfering and compacting machine comprises a base device, a feeding device is arranged on the top of the base device, and a limiting device is arranged in the middle of the feeding device; the feeding device comprises a plurality of parallel brackets, two transmission shafts are arranged on the top of the brackets for parallel rotation up and down, a pressure roller is arranged in the middle of the transmission shaft, a gear is arranged at one end of the transmission shaft, and a first motor is installed at the end of the transmission shaft away from the gear; the limiting device comprises an adjusting frame, a lead screw is rotatably arranged at the bottom of the adjusting frame, the lead screw thread is a forward and reverse thread, a second motor is installed at one end of the lead screw, two moving blocks are symmetrically arranged on the lead screw, a milling cutter is rotatably arranged on the top of the moving block, a third motor is installed on the top of the milling cutter, a limiting frame is fixedly arranged on the outer side of the moving block, and a plurality of limiting wheels are rotatably arranged at the bottom of the limit frame.

[0007] Furthermore: the base device includes a load-bearing frame, and a processing table is fixedly arranged on the top of the load-bearing frame.

[0008] Furthermore: the adjustment frame and the load-bearing frame are welded together.

[0009] Furthermore: the transmission shaft is connected to the bracket bearing, and the gear is connected to the transmission shaft with a flat key.

[0010] Furthermore: the second motor is connected to the adjusting frame by bolts, and the second motor is connected to the lead screw by a key.

[0011] Furthermore: the limiting frame and the moving block are integrally formed.

[0012] Furthermore: the limiting wheels are arranged in groups of two, and the limiting wheels are connected to the limiting frame bearings.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The bracket supports the first motor to drive the coaxial transmission shaft to rotate. The transmission shaft drives the gear at one end to rotate and mesh with another gear on the top to rotate synchronously. As a result, the transmission shaft at the top rotates in the opposite direction. The two transmission shafts respectively drive the pressure rollers to rotate, squeeze and drive the cushion block in the middle to move backward. In this process, the cushion block is squeezed and compacted, realizing the compaction function of the device. The design of the pressure roller driving the cushion block to move enables compaction and chamfering to be carried out synchronously, shortening the processing time, facilitating continuous processing, and improving the processing effect.

[0015] 2. When the pad moves along the processing table, the limit frame supports the limit wheels to roll along the two sides of the pad respectively. The limit wheels limit the moving direction of the pad in groups of two to prevent its tilting from affecting the subsequent chamfering accuracy, thereby realizing the centering positioning of the pad, making the processing size more in line with the specifications and reducing errors. The moving block supports the third motor to drive the milling cutter to rotate, and the tilted milling cutter cuts the edge of the pad passing through the bottom to realize the chamfering process. When the width of the pad to be processed changes, the adjustment frame supports the second motor to drive the lead screw to rotate, driving the two moving blocks to open and close synchronously. During this process, the milling cutter and the limit wheel both follow the movement to realize synchronous adjustment. By installing the milling cutter and the limit wheel on the moving block at the same time, the device can ensure centering when processing pads of different widths, reducing the difficulty of adjustment.
