Description

Technical Field

[0001] The utility model relates to the technical field of double-sided tapping devices, in particular to a double-sided tapping device for nuts. Background Art

[0002] A double-sided tapping device for nuts is a device for manufacturing nuts. Nuts are common mechanical parts, usually used to cooperate with screws to fix or connect parts. The function of the double-sided tapping device for nuts is to perform tapping processing on both sides of the nut at the same time to improve production efficiency and processing accuracy. Publication No. CN208840642U discloses a double-sided tapping device for nuts. A nut fixing device is arranged on the upper end of a frame, and a first tapping device and a second tapping device are respectively arranged on both sides of the nut fixing device. The first tapping device and the second tapping device are used to tap the two sides of the nut through hole twice. The secondary tapping can improve the quality of the internal thread of the nut, reduce thread defects, reduce the defective rate of the nut, and reduce losses. However, the upper fixing clamp block and the lower fixing clamp block for fixing the nut in the device are fixedly installed and cannot be disassembled. After a period of use, a gap will be generated in the groove after the nut is placed due to processing wear, resulting in reduced fixing firmness of the nut and reduced nut tapping processing efficiency. Therefore, it needs to be improved. Utility Model Content

[0027] Embodiment 2

[0028] See also Figure 2 , 3 A functional groove 20 is provided on the surface of the machine 1, and a slide bar 23 is symmetrically fixedly installed on the surface of the machine 1.

[0029] Working principle: When replacing the upper fixed clamp 8, the operator uses a tool to unscrew the screw 17 to disassemble and assemble the upper fixed clamp 8. When replacing the lower fixed clamp 10, the operator presses the block 15 downward with force, and then the block 15 slides in the groove 13, and the strong spring 14 is compressed. Then another operator pulls the movable block 9 outward, and then the slider 11 slides in the slide groove until one side of the movable block 9 is located above the block 15. At this time, the operator releases the pressure on the block 15 until the movable block 9 slides completely, thereby removing the lower fixed clamp 10, and using the slider 11 to slide in the slide groove A12, the lower fixed clamp 10 is quickly installed. Similarly, when installing the movable block 9 and the lower fixed clamp block 10, push the movable block 9, and then the slider 11 slides in the slide groove, and the strong spring 14 is used to fix the stopper 15 to one side of the lower fixed clamp block 10, so that the lower fixed clamp block 10 is firmly installed, and the upper fixed clamp block 8 and the lower fixed clamp block 10 are detachable, which is convenient for replacing the upper fixed clamp block 8 and the lower fixed clamp block 10, thereby improving the nut tapping processing efficiency. After the replacement is completed, when operating the equipment, the operator starts the driver 2, and then the two sets of drivers 2 slide relatively on the upper surface of the machine table 1, and the tapping motor 3 is started. The tapping motor 3 drives the tap 4 to rotate, and the nut can be tapped.
