Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tapping machine, and particularly relates to a tapping machine for flange nut. BACKGROUND

[0002] The tapping machine is a kind of mechanical processing equipment for processing internal thread, screw or splines on the inner side of the hole of various parts with different specifications of through hole or blind hole such as machine housing, equipment end face, nut and flange plate. The tapping machine is commonly used in tapping processing of nut.

[0003] In the related art, a horizontal nut tapping machine is provided, in which a tap with a lengthened and bent shank is suspended in the main shaft and rotates under the driving of a motor. The nut is pushed forward to engage with the tap under the pushing force of a cylinder. When the tap passes through the nut, the same thread specification (pitch) as the tap is generated on the nut, and the tapping process is completed.

[0004] However, since there are many types of nuts, the shape of some nuts is not standardized. When the cylinder pushes the nut to engage with the tap, the nut is offset or misaligned with the tap during the pushing process, resulting in poor tapping effect of the nut and failing to meet the use requirements, and finally the nut can only be discarded.

[0049] Referring to Figure 6 and Figure 7The limiting plate 33 has a machining groove 332 that communicates with the limiting groove 331. The machining assembly 4 consists of several third driving components, belts, and taps 41. The third driving components are also drive motors. When the machining assembly 4 is working, the drive cylinder 311 drives the moving table 32 and the limiting plate 33 to move towards the tap 41. The limiting block 34 is affected by the reset component 35 (see...). Figure 5 The function of the tap 41 is to limit the flange nut inside the limiting groove 331. After the tap 41 penetrates the flange nut, it continues to be inserted into the machining groove 332, thereby realizing the tapping of the flange nut and making the inner wall of the flange nut have internal threads.

[0050] Reference Figure 6 and Figure 7 After machining, the flange nut is left on tap 41, and the telescopic rod of the drive cylinder 311 retracts, causing the limit block 34 to overcome the torsion spring 351 (see...). Figure 5 The torque of the tap opens outward, causing the flange nut after tapping to disengage from the limiting groove 331; then the limiting plate 33 continues to clamp the next flange nut, which remains on the tap 41 after processing, and can push the previous nut to move, and so on.

[0051] Reference Figure 2 The discharge assembly 5 includes four discharge boxes 51 located on the back side of the machine body 1. Finally, the flange nuts on the tap 41 fall into the discharge boxes 51, and the workers take out the processed flange nuts from the discharge boxes 51.

[0052] Reference Figure 6 The moving table 32 has a collection slot 322 that communicates with the processing slot 332. The lower side of the moving table 32 is provided with a collection component 6 for collecting metal shavings generated after tapping the flange nut. The collection component 6 includes a collection box 61 and a blower 62. The collection box 61 is fixedly installed on the lower side of the moving table 32. When the moving table 32 moves, it drives the collection box 61 to move synchronously. The blower 62 is fixed on the side of the feeding track 23 along the length of the feeding track 23. When the blower 62 is started, it blows towards the collection box 61, so that the shavings in the processing slot 332 and the collection slot 322 fall into the collection box 61, thereby preventing the shavings generated by tapping from flying around and reducing the time required to clean up the shavings.

[0053] Reference Figure 6 and Figure 7, the end side of the limiting plate 33 is provided with a barrier net 621, which avoids debris from splashing into the fan 62, and improves the protection performance of the fan 62. The storage assembly 6 further comprises a drawer box 63, the outer side of the drawer box 63 is fixed with a handle 631, and the lower edge of the storage box 61 is provided with a drawer slot 611 for inserting and sliding the drawer box 63, so that the debris in the storage box 61 finally falls into the drawer box 63, and when the debris in the drawer box 63 is collected, the drawer box 63 is pulled out from the drawer slot 611 through the handle 631, and the debris is collected and treated.

[0054] Referring to Figure 8 and Figure 9 , the inner bottom of the drawer box 63 is fixedly provided with four magnetic attraction members 632, which are made of magnet, so that the debris in the storage box 61 can be more effectively attracted to the bottom side of the drawer box 63.

Since the tapping machine will vibrate during work, the installation stability of the drawer box 63 in the drawer slot 611 is improved by the cooperation of the compression spring 642 and the arc-shaped protrusion 641, and the possibility of loosening or displacement of the drawer box 63 in the drawer slot 611 is reduced.

[0055] The implementation principle of the embodiment of the application is:

[0056] During the machining of the tapping machine, first, the flange nut to be machined is transmitted to the accommodating groove 12 on the upper side of the machine body 1 through a conveyor belt or manually, then the first driving member 21 is controlled by the control panel 11 to drive the toggle lever 22 to reciprocate, so that the flange nut to be machined in the accommodating groove 12 falls into the feeding groove 231 and slides along the length direction of the feeding groove 231, and the flange nut to be machined falls into the limiting groove 331 on the limiting plate 33, and the limiting block 34 further limits the flange nut in the limiting groove 331;

[0057] Secondly, the moving table 32 and the limiting plate 33 are driven by the driving cylinder 311 to move towards the direction close to the tap 41, the tap 41 continues to be inserted into the machining groove 332 after penetrating the flange nut, so as to realize tapping machining of the flange nut, so that the inner wall of the flange nut has internal threads; the flange nut after machining remains on the tap 41, the driving cylinder 311 resets, and in this process, the limiting block 34 opens outward against the torsional force of the torsional spring 351, and after the flange nut is detached from the limiting groove 331, the limiting block 34 resets under the action of the torsional spring 351, and then the next flange nut is clamped, the previous nut is moved, and the cycle is repeated, and finally the nut on the tap 41 falls into the discharge box 51.

[0058] At the same time in the tapping process, start the fan 62, make the fan 62 blow to the direction close to the storage box 61, make the debris fall into the inside of the storage box 61 through the processing groove 332 and the storage groove 322, and through the setting of the magnetic attraction piece 632, the debris in the inside of the storage box 61 is adsorbed on the inside bottom side of the drawer box 63, when the debris in the inside of the drawer box 63 is collected, take out the drawer box 63 from the inside of the drawer groove 611 through the handle 631, collect the debris, so as to avoid the debris produced by tapping flying everywhere, reduce the time needed for cleaning the debris.

[0059] Through the above setting, under the premise of realizing the positioning and clamping of the flange nut in the processing process, the debris produced in the processing is also collected through the storage assembly 6, so as to improve the stability of the flange nut in the processing process, enhance the processing quality of the flange nut, avoid the debris produced by tapping flying everywhere, and make the flange nut processing more environmentally clean.
