[0030] like Figures 1 to 8As shown, an embodiment of the present invention provides a clamping device for forging automobile parts, which includes a processing box 110, a support plate 120, a punching assembly and an adjustment assembly.

[0031] The processing box 110 is placed on the ground. The processing box 110 is hollow inside. The hollow chamber inside the processing box 110 is the processing chamber. The side wall of the processing box 110 is provided with a material exchange port connecting the processing chamber and the external environment. The processing box 110 is provided with a blocking cover, which can block or open the material exchange port. Further, in order to facilitate the staff to observe the internal conditions of the processing box 110, the blocking cover is generally set to a transparent material, for example, the blocking cover is an acrylic plate or glass.

[0032] The support plate 120 is horizontally arranged in the processing chamber. The support plate 120 has a horizontal upper end surface. Two support blocks 130 are arranged on the support plate 120. The two support blocks 130 are arranged in parallel and spaced apart on the support plate 120. Each support block 130 can support a car yoke 150. Specifically, a storage groove is arranged at the upper end of each support block 130, and each car yoke 150 can be placed in a storage groove. Two extrusion blocks 140 are arranged in the processing box 110. Each extrusion block 140 is arranged corresponding to a support block 130, and each extrusion block 140 is arranged above a support block 130. Each extrusion block 140 can extrude a car yoke 150 on a support block 130, that is, each extrusion block 140 and a support block 130 jointly clamp a car yoke 150.

[0033] Each automobile yoke 150 has a first hole position, a second hole position and a third hole position. When the automobile yoke 150 is punched, holes are punched in the first hole position, the second hole position and the third hole position of the automobile yoke 150, wherein the first hole position and the second hole position are always in a coaxial state, the axis of the third hole position is in the same plane as the axis of the first hole position, and the axis of the third hole position is perpendicular to the axis of the first hole position. The first hole position and the second hole position of the two automobile yokes 150 have a first coaxial state, and the punching assembly is used to punch holes in the two automobile yokes 150 when the two automobile yokes 150 are in the first state. When the punching assembly punches holes in the two automobile yokes 150 at the same time, the first hole position and the second hole position on the two automobile yokes 150 are both punched. It is easy to understand that when the two automobile yokes 150 are in the first state, the punching assembly can punch four holes at one time. The third hole positions of the two automobile yokes 150 have a coaxial second state. The punching assembly is used to punch holes in the two automobile yokes 150 when the two automobile yokes 150 are in the second state. When the punching assembly punches holes in the two automobile yokes 150 at the same time, the third hole positions on the two automobile yokes 150 are all punched. It is easy to understand that when the two automobile yokes 150 are in the second state, the punching assembly can punch two holes at one time. By punching holes in the two automobile yokes 150 at the same time, the efficiency of punching holes in the automobile yokes 150 is improved.

[0034] The adjustment component is used to adjust the two automobile yokes 150 from the first state to the second state. The two automobile yokes 150 are initially set to be in the first state. After the punching component completes punching the first hole position and the second hole position of the automobile yoke 150, the adjustment component adjusts the two automobile yokes 150 from the first state to the second state. The punching component punches the third hole position of the automobile yoke 150 when the two automobile yokes 150 are in the second state.

[0035] The clamping device for forging automobile parts of the present invention, when punching an automobile yoke 150, two automobile yokes 150 are placed on two support blocks 130 at the same time, each support block 130 and an extrusion block 140 clamp one automobile yoke 150, when the support block 130 and the extrusion block 140 clamp the automobile yoke 150, the first hole position and the second hole position of the two automobile yokes 150 are coaxial, at this time, a punching assembly is used to punch the two automobile yokes 150, the punching assembly punches the first hole position and the second hole position on the automobile yoke 150 at one time, then, the adjustment assembly is used to adjust the two automobile yokes 150, so that the third hole positions of the two automobile yokes 150 are in a coaxial state, the punching assembly punches the third hole position again, and the adjustment assembly cooperates with the punching assembly to achieve one-time completion of the punching of the two automobile yokes 150, thereby improving the punching efficiency of the automobile yoke 150.

The first arc plate 160 and the second arc plate 170 are coaxially arranged, so when the first arc plate 160 rotates in the first arc groove, the first arc plate 160 can enter the second arc groove, and correspondingly, when the second arc plate 170 rotates in the second arc groove, the second arc plate 170 can enter the first arc groove. In the initial state, the first arc plate 160 and the second arc plate 170 are both in a relatively static state, the first arc plate 160 is in the first arc groove, and the second arc plate 170 is in the second arc groove, and the first arc plate 160 and the second arc plate 170 jointly clamp the automobile yoke 150. The first driving member is used to drive the first arc plate 160 and the second arc plate 170 to rotate simultaneously when the first arc plate 160 and the second arc plate 170 are coaxial. In the initial state, the first hole position and the second hole position of the two automobile yokes 150 are in a coaxial state. When the punching assembly completes punching the first hole position and the second hole position on the two automobile yokes 150, the first driving member is started. When the first driving member is started, the position of one automobile yoke 150 clamped by the first arc plate 160 and the second arc plate 170 changes. According to the position setting of the storage slot on the first arc plate 160, after the first arc plate 160 and the second arc plate 170 rotate, the two automobiles The third hole position of the yoke 150 is in a coaxial state, but at this time, there is an angle between the extension direction of the third hole position and the extension direction of the punching assembly. The second driving member can change the punching position of the automobile yoke 150 by the punching assembly. It is easy to understand that the second driving member can ensure that the extension direction of the third hole position is the same as the punching direction of the punching assembly. With the cooperation of the first driving member and the second driving member, after the punching of the first hole position and the second hole position of the automobile yoke 150 is completed, the first driving member and the second driving member are gradually started, thereby adjusting the third hole positions of the two automobile yokes 150 and the punching direction of the punching assembly to the same state.

The support block 130 connected to the first arc plate 160 is slidably connected to the support plate 120, and the direction in which the support block 130 slides on the support plate 120 is the same as the direction in which the second plate 172 slides on the first plate 171. Specifically, a slide groove is provided on the support plate 120, and the support block 130 connected to the first arc plate 160 is slidably arranged along the slide groove. In the initial state, the first hole position and the second hole position of the two automobile yokes 150 are in a coaxial state, and the axis direction of the first hole position and the second hole position is in the horizontal direction. The extension direction of the slide groove is the same as the direction in which the first hole position and the second hole position are coaxial in the initial state. In the initial state, the second arc plate 170 is a complete arc shape, and the two automobile yokes 150 are in a non-contact state. To ensure that the punching assembly can stably punch the first hole position and the second hole position of the two automobile yokes 150, firstly drive the first plate 171 and the second plate 172 to slide relative to each other, and the contours of the first plate 171 and the second plate 172 are transformed into a special shape.
