Problems solved by technology

[0002] When auto parts are used, they are usually installed by bolt connection. The mounting holes on auto parts are usually processed by punching. At present, auto parts are punched with mold assistance, and the punch reciprocates to achieve continuous punching. Frequent use will gradually reduce its strength and cause deformation, which will lead to a decrease in punching quality, specifically position accuracy and contour accuracy, which will affect later assembly or thread processing

Embodiment 1

[0030] see figure 1 , figure 2 and Figure 4 , a stamping drilling device for auto parts processing, including a reciprocating drive shaft 1 and a punch 2, the reciprocating drive shaft 1 is used to provide the up and down reciprocating action required for stamping, and the punch 2 is used to remove materials from parts on the stamping table It also includes a dynamic switching mechanism 3. The function of the dynamic switching mechanism 3 is to continuously switch the punches 2 in sequence during the punching process, so as to avoid the phenomenon of overheating and damage to the punches 2. The dynamic switching mechanism 3. It includes positioning plate 31, elastic telescopic beam 32 and rotating sleeve 33. Positioning plate 31 plays the role of fixing and installation. The lower moving beam 321 is under the action of the tension spring in the telescopic sleeve, the moving beam 321 is in the return state, the rotating sleeve 33 is arranged in the middle of the positioning...

Embodiment 2

[0032] see Figure 2-4, because the embodiment 1 realizes the punch 2 alternate switching function in the punching process, and the alternate switching involves a movable matching structure, and then there will be a problem that the punch is prone to misalignment, resulting in a decrease in accuracy. For this reason, this embodiment and implementation The difference of Example 1 is that the upper sleeve 33 is provided with an annular limiting disc 333 located at the lower part of the toggle arm 331, the annular limiting disc 333 is rotationally connected with the rotating sleeve 33, and the lower end surface of the annular limiting disc 333 is provided with a radial distribution. One side of the moving beam 321 is fixedly provided with a guide shaft 3213 slidingly matched with the limit chute 3331, and then the annular limit plate 333 is always in a static state, and when the guide shaft 3213 moves the limit chute The punch 2 and the reciprocating drive shaft 1 are coaxially d...

Embodiment 3

[0034] see Figure 5 The difference with Embodiment 1 is that it also includes a transmission mechanism 34. The outer wall of the reciprocating drive shaft 1 is fixedly provided with a drawbar 11 positioned on the upper part of the positioning disc 31. The transmission mechanism 34 is arranged on the upper part of the positioning disc 31 and is connected to the drawbar 11 and The rotating sleeve 33 cooperates, and when the reciprocating drive shaft 1 performs a reciprocating action, the rotating sleeve 33 rotates in one direction through the transmission mechanism 34; specifically, the transmission mechanism 34 includes a driving rod 341 and a driving turntable 342, a driving turntable 342 and a positioning disk 31 The eccentric shaft 3421 which is rotationally connected with the driving rod 341 is fixedly arranged on one of its disk surfaces, and one end of the driving rod 341 is rotationally connected with the eccentric shaft 3421. Ring 332, that is to say, when the reciproc...

Abstract

The invention discloses a punching and drilling device for automobile part machining. The punching and drilling device comprises a reciprocating driving shaft and punches and further comprises a dynamic switching mechanism. According to the punching and drilling device, the dynamic switching mechanism is arranged between the punches and the reciprocating driving shaft and comprises a positioning disc, at least three elastic telescopic beams and a rotating sleeve, the elastic telescopic beams are arranged on the lower portion of the positioning disc and distributed centripetally, the number ofthe punches corresponds to that of the elastic telescopic beams, and the punches are slidably mounted at the centripetal ends of the elastic telescopic beams; the rotating sleeve is rotatably connected with the positioning disc and provided with a shifting arm, the shifting arm can shift the elastic telescopic beams to act, the shifting arm rotates by a circle along with the elastic telescopic beams and can shift the elastic telescopic beams in turn at one time, and thus the punches at different positions can enter the working positions; and replacement type punching of the punches is achieved, the service life of the punches is greatly prolonged, and the punching precision is improved.
