Description

Technical Field

[0001] The present invention relates to the technical field of sheet metal processing equipment, in particular to a multi-axis tapping device for sheet metal of an electrical cabinet. Background Art

[0002] In the production process of electrical cabinets, the side wall panels of the cabinet body are generally processed through sheet metal and then assembled into shape. Since there are many types of layers and components in the electrical cabinet, a large number of threaded holes need to be reserved on the wall panel sheet metal to adapt to the subsequent assembly process. Most of these threaded holes are multi-row fixed-distance array holes, which are punched and then tapped during processing. Due to the large number of holes, tapping requires each hole to be processed in turn, and the process is very cumbersome. In addition, when the electrical cabinets are mass-produced, the number of wall panel sheet metal parts that need to be tapped is also very large, making the tapping process more time-consuming and labor-intensive.

[0003] Most of the current tapping devices are still at the level of conventional tapping machines. Conventional tapping machines can only tap a single hole at a time, which is very cumbersome to operate for electrical cabinet sheet metal parts. In addition, alignment is required before tapping to prevent the tap from being misaligned with the threaded hole to be tapped. The electrical cabinet sheet metal parts themselves are heavy, and alignment is even more cumbersome and laborious. Therefore, there is an urgent need for a tapping device to improve the tapping efficiency of electrical cabinet sheet metal parts.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a new technical solution. Summary of the Invention

DETAILED DESCRIPTION

[0024] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0025] Example 1

[0026] See also Figures 1 to 3 , a multi-axis tapping device for sheet metal of an electrical cabinet, used for tapping array through holes opened on a sheet metal part 5, comprising an operating table 1, on which at least one slide rail 11 is fixedly provided, and a loading platform 2 is slidably mounted on the slide rail, and the sheet metal part 5 is limited and fixed on the loading platform; a tapping mechanism 3 is installed above the operating table 1, and the tapping mechanism includes a plurality of liftable taps 33, and each tap is evenly arranged in an array; a positioning mechanism 4 is also installed on the side of the operating table 1, and the positioning mechanism includes a pin 41 that can be retracted in the vertical direction, and the side of the loading platform has a flange 23 extending to the outside of the operating table, and a plurality of positioning holes 231 that are adapted to the size of the pins are evenly opened on the flange along the length direction of the slide rail according to the spacing of the array through holes on the sheet metal part.

[0027] The positioning mechanism 4 also includes a limit block 42 fixed to the side of the operating table, and a limit hole is provided on the limit block. The limit hole is a through hole arranged vertically in the axial direction, and the size of the limit hole is adapted to the diameter of the pin. The pin is slidably inserted in the limit hole of the limit hole and moves axially along the limit hole.

[0028] A return spring 43 is also mounted on the latch 41. The stopper blocks 42 are arranged in parallel, one above the other, with their stopper holes coaxially arranged. One end of the return spring is fixedly connected to the top surface of the lower stopper block, while the other end is fixedly mounted on the portion of the latch located between the two stopper blocks. Specifically, a baffle is integrally formed on the portion of the latch located between the two stopper blocks. One end of the return spring is fixedly connected to the baffle, while the other end is fixedly connected to the lower stopper hole. During the tapping process, it is necessary to control the loading platform to move along the slide rail. If the pin has been inserted into the positioning hole 231, pull the bottom end of the pin to disengage the pin from the positioning hole and move the loading platform. The top end of the pin is smoothly set in an arc shape until the loading platform moves to the next positioning hole and is coaxial with the pin. There is no need to manually pull the pin during this process. After the loading platform moves into place, the pin will be pushed into the next limit hole under the action of the reset spring. The spacing between the limit holes is an integer multiple of the spacing between the threaded holes to be tapped in the sheet metal part (the specific multiple is adapted to the number of taps parallel to the slide rail direction). In this way, the loading platform can achieve a single precise movement and the tap can be accurately inserted into the next untapped hole for tapping.

[0029] A plurality of limiting posts 22 are installed on the upper surface of the loading platform 2 . The limiting posts are arranged around the sheet metal parts placed on the loading platform and the limiting posts are arranged to fit the edges of the sheet metal parts.

[0030] A sliding seat 21 is fixedly provided at the bottom of the loading platform 2 , and the sliding seat is slidably installed on the slide rail 11 .

[0031] The position of the limit post 22 and the spacing between the taps 33 are adjustable. The main purpose of the adjustable limit post is to prevent interference when placing the sheet metal parts, which may cause the sheet metal parts to be placed unsteadily and affect the tapping.

[0032] The tapping mechanism 3 also includes a lifting platform 31 that can move up and down, and a plurality of motors 32 are installed in an array on the lifting platform. Each tap is installed in a motor and driven by the motor. The motor is a pneumatic or hydraulic motor. The motor is movably installed on the lifting platform by cooperating with a slide rail through a lockable slider or by adopting a screw adjustment method. Among them, the arrangement of the motor and the taps installed on the motor is set according to the number and position of the threaded holes to be tapped on the current sheet metal. The specific adjustment method of the motor is relatively common in this field and belongs to the conventional technical means, which will not be described here. In addition, multiple motors can be powered by the same energy supply system. For example, the pneumatic motor uses the same compressor shunt power supply, and the hydraulic motor uses the same hydraulic pump shunt power supply, which can improve the synchronization of each motor and thereby improve the consistency of each threaded hole.

[0033] The loading platform 2 is also fixedly provided with a movable pull ring 24, which is located on the side of the loading platform. An operator can drive the loading platform to move by pulling the movable pull ring.

[0034] In this embodiment, the loading platform is detachably connected to the slide rail. For sheet metal parts with threaded holes of different specifications, the loading platform can be replaced according to the specifications of the sheet metal parts and the positions of the motor and tap can be adjusted during operation to adapt.

[0035] Example 2

[0036] Similar to Example 1, the difference is that the thickness of the operating table is less than the distance between the two limit blocks. In this case, an extension block 12 is fixedly installed below the side of the operating table 1. One of the two limit blocks is fixed to the side of the operating table, and the other is fixed to the extension block. The extension block is fixed to the operating table by welding. Before welding, the pin is first inserted into the limit hole of the lower limit block, and then the return spring is fixed. After that, the pin is aligned with the upper limit hole before welding.

[0037] The beneficial effects of the present invention are: by carrying the sheet metal parts on the movable loading platform for movement, and cooperating with the tapping mechanism with multiple taps, the stability of movement and the efficiency of tapping during operation are greatly improved. At the same time, combined with the mutually cooperating positioning holes and the positioning mechanism with pins, the accuracy of the moving distance of the sheet metal parts after a single tapping is guaranteed, and the accuracy of the tap position in the next tapping process is guaranteed.

[0038] Although embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention, and that those skilled in the art may make changes, modifications and variations to the above embodiments within the scope of the present invention.
