Description

Technical Field

[0001] The utility model relates to the technical field of tapping machines, in particular to a tapping machine for nut processing. Background Art

[0002] Tapping machine is a kind of mechanical processing equipment that processes internal threads, screws or thread buckles on the inner side of the holes of various parts with different specifications of through holes or blind holes, such as machine housings, equipment end faces, nuts, flanges, etc. Tapping machines are also called tapping machines, thread tapping machines, thread tapping machines, automatic tapping machines, etc. Tapping machines are divided into drilling tapping machines, hole expansion tapping machines, etc. The fully automatic tapping machine has the highest degree of automation. When working, as long as the part blank is placed in the hopper, it can automatically feed, automatically position, automatically clamp, automatically tap, and automatically unload. A worker can operate multiple devices at the same time, with high production efficiency, which can significantly save labor costs! High-quality tapping machines have the characteristics of novel design, reasonable structure, simple and easy to use, high degree of automation, easy to use, high efficiency, maintenance-free, and extremely high cost performance. The various nuts processed by high-quality nut tapping machines have high finish and high qualified rate of finished products.

[0003] Chinese patent CN211516316U discloses a nut tapping machine.

During use, when the tapping drill bit descends to tap the nut, the nut pressing sleeve at the bottom end of the casing will first press and fix the nut to be tapped. As the tapping drill bit continues to descend, the spring contracts. When the tapping is completed, the tapping drill bit is controlled to rise, first the spring rebounds to the initial state, and then the tapping drill bit drives the nut pressing sleeve to rise and automatically separates from the nut, thereby realizing automatic pressing and fixing of the nut during tapping, and automatically separating from the nut after the tapping is completed, thereby greatly improving the efficiency of the tapping operation.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of a tapping machine for nut processing provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the structure of the front cross-section shown; Figure 3 for Figure 1 The tapping machine for nut processing comprises a bottom plate 1, a receiving box 2 is fixedly connected to the upper surface of the bottom plate 1, and baffles 15 are fixedly connected to the front and rear sides of the top of the receiving box 2 in a transverse direction.

[0023] An electric slide rail 16 is laterally fixedly connected to the inner side surface of a baffle 15 , and a push plate 17 in contact with the top of the storage box 2 is fixedly connected to the surface of the sliding part driven by the electric slide rail 16 .

[0024] A support rod 3 is vertically fixedly connected to one side of the top of the storage box 2, a cross plate 4 is fixedly connected to the top of the support rod 3, a first electric telescopic rod 5 is vertically fixedly connected to the lower surface of the cross plate 4, a lifting plate 6 is fixedly connected to the bottom end of the first electric telescopic rod 5, and a tapping mechanism is provided on the lower surface of the lifting plate 6;

[0025] The inner cavity of the storage box 2 is vertically fixedly connected with a second electric telescopic rod 18, and the top of the second electric telescopic rod 18 is vertically fixedly connected with a positioning column 19. The top of the positioning column 19 can be pulled to the outside of the bottom plate 1 and is below the tapping mechanism.

[0026] After the second electric telescopic rod 18 is extended, it drives the positioning column 19 to move to the top of the receiving box 2. The staff can then put the nut to be processed on the surface of the positioning column 19, and then position the nut during the placement process to ensure that the nut is located below the tapping mechanism, thereby improving the tapping processing efficiency of the nut and improving the quality of the finished nut after tapping.

[0027] During the tapping process, the second electric telescopic rod 18 contracts, driving the positioning column 19 to disengage from the nut, thereby improving the stability of the nut tapping process. After the processing is completed, the top of the positioning column 19 remains level with the top of the receiving box 2. After the electric slide rail 16 drives the push plate 17 to move, the waste on the surface of the receiving box 2 can be pushed off, and the top of the receiving box 2 can be automatically cleaned, which is beneficial to the subsequent placement of the nut, and then beneficial to the continuous nut tapping production and processing.

[0028] A collecting box 20 is placed on the upper surface of the base plate 1, and the collecting box 20 is located on the other side of the receiving box 2. An observation window 23 is provided on the surface of the collecting box 20. One end surface of the lifting plate 6 can be slidably mounted on the surface of the supporting rod 3.

The bottom end of the vertical cylinder 11 is fixedly connected with a nut pressing sleeve 12, and the lower surface of the connecting disk 10 and the top of the vertical cylinder 11 are vertically fixedly connected with a plurality of springs 13.

[0033] The nut pressing sleeve 12 is adapted to the nut. After the first electric telescopic rod 5 is lowered, the nut pressing sleeve 12 is sleeved on the outside of the nut. When the tapping tap 14 taps the nut, the stability of the nut is improved and the spring 13 is squeezed to generate elastic force. After the tapping is completed, the elastic force of the spring 13 pushes the nut pressing sleeve 12, so that the nut can be separated from the surface of the tapping tap 14.

[0034] The working principle of the tapping machine for nut processing provided by the utility model is as follows:

[0035] After the second electric telescopic rod 18 is extended, it drives the positioning column 19 to move to the top of the receiving box 2. The staff can put the nut to be processed on the surface of the positioning column 19, and then position the nut during the placement process to ensure that the nut is located below the tapping mechanism, thereby improving the tapping efficiency of the nut and the quality of the finished nut after tapping. During the tapping process, the second electric telescopic rod 18 contracts to drive the positioning column 19 to separate from the nut, thereby improving the stability of the nut during tapping. After the processing is completed, the top of the positioning column 19 remains level with the top of the receiving box 2. After the electric slide rail 16 drives the push plate 17 to move, the waste on the surface of the receiving box 2 can be pushed off, and the top of the receiving box 2 can be automatically cleaned.
