Description

Technical Field

[0002] Electric meter is the abbreviation of electric energy meter, which is an instrument used to measure electric energy. It is also called watt-hour meter, fire meter, and kilowatt-hour meter. It is widely used in our daily life. The electric meter shell includes a lower shell and an upper shell. Screw sleeves are installed at the four corners of the lower shell, and holes are opened at the four corners of the upper shell. Later, the lower shell and the upper shell are connected together by passing the screws through the holes and twisting them into the screw sleeves.

The soldering mechanism in the existing processing device is not convenient for adjusting the positions of the four sets of screw sleeves according to the size of the lower shell, and soldering cannot be performed synchronously. On the one hand, the processing efficiency is low, and on the other hand, the practicability of the device is reduced. Usually, the upper shell and the lower shell are processed separately, resulting in a deviation between the position of the screw sleeves inside the lower shell and the position of the holes opened in the upper shell, which makes it impossible to assemble later.

Therefore, when the drill head 709 and the drilling head 713 are rotating and moving downward, drilling and punching of the workpiece can be achieved.

[0058] Working principle and use process of the device: In real life, the meter housing is usually composed of three parts: the lower housing 102, the screw sleeve 104 and the upper housing 106. The upper housing 106 is provided with a perspective screen to facilitate the user to see the meter display installed inside the meter housing. In real life, in order to facilitate the threaded connection between the lower housing 102 and the upper housing 106, the length of the screw sleeve 104 is greater than the internal height of the lower housing 102. The present invention first transfers the lower housing 102 on the first conveyor 101 to the top of the workbench 108 through the first mechanical arm 109, and under the action of the output end of the first servo motor 304, the two groups of clamping plates 305 are close to each other to fix the lower housing 102, and the screw sleeve 104 on the second conveyor 103 is transferred to the inside of the four groups of mounting plates 519 in turn through the second mechanical arm 110, and the fixing mechanism 6 clamps the top of the screw sleeve 104, and then under the action of the output end of the second stepper motor 508, the lifting plate 509 moves upward, the purpose is to In order not to block the subsequent rotation of the rotating member 501, the rotating member 501 is driven to rotate under the action of the output end of the first driving motor 502, so that the movable member 518 faces the workbench 108, and the output end of the third servo motor 513 and the output end of the fourth servo motor 517 cooperate to change the spacing between the front and rear movable members 518 and the spacing between the left and right movable members 518, thereby changing the spacing between the front and rear screw sleeves 104 and the spacing between the left and right screw sleeves 104. After that, the output end of the second stepping motor 508 rotates in the opposite direction to drive the lifting plate 509 to move downward, which is well suitable for inserting four groups of fixed screw sleeves 104 at the four corners of the lower shell 102 of different sizes. Then, the output end of the electric push rod 520 drives the soldering head 526 to move downward, aligning the contact position between the screw sleeve 104 and the inner bottom wall of the lower shell 102, and the output end of the second driving motor 522 drives the soldering head 526 to rotate, thereby fixing the screw sleeve 104 inside the lower shell 102;

[0059] After soldering is completed, under the action of the output end of the first stepper motor 204, the workbench 108 moves to the drilling and punching mechanism 7, and the output end of the third stepper motor 704 drives the third screw rod 702 to rotate, so that the moving part 705 moves left and right, changing the horizontal position of the drilling head 709, and under the cooperation of the first cylinder 706 and the drilling motor 708, the top of the screw sleeve 104 welded inside the lower shell 102 is drilled. After the four groups of screw sleeves 104 are drilled, since the length of the screw sleeve 104 is greater than the internal height of the lower shell 102, the third mechanical arm 111 can only be used to move the first screw sleeve 104 to the lower shell 102. The upper shell 106 on the three conveyors 105 is transferred to the top of the screw sleeve 104, and the lifting block 406 is driven up and down by the output end of the electric lifting rod 405, so that the height of the lifting block 406 is adapted to the height of the upper shell 106. Then, the four corners of the upper shell 106 are clamped by four groups of pressing grooves 407 to fix the upper shell 106. The positions of the four screw sleeves 104 below can well locate the positions of the holes required at the four corners of the upper shell 106. Finally, the upper shell 106 is drilled by the drilling and punching mechanism 7. It is convenient and fast, and the whole process is automated to meet the needs of the staff. (The processed lower shell 102, screw sleeve 104 and upper shell 106 are as shown in the figure) Fig.15 shown)
