DETAILED DESCRIPTION

[0025] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0026] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0027] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 8The figure shows a structural diagram of a punching device for an automobile control arm provided by an embodiment of the present invention, comprising a base 1, wherein guide rods 11 are fixedly installed on all four sides of the base 1, and a top plate 12 is fixedly installed on the top of multiple groups of guide rods 11. A hydraulic cylinder 2 is fixedly installed on the surface of the top plate 12, and a pressure plate 21 is fixedly installed on the telescopic end of the hydraulic cylinder 2. A processing groove 3 is provided on the surface of the base 1, and the processing groove 3 is set as a Y-shaped structure. A control arm body 4 is placed in the processing groove 3. A punching mechanism 5 that cooperates with the control arm body 4 is provided in the base 1, and the punching mechanism 5 includes a clamping assembly 51 and a punching assembly 52. ​​The clamping assembly 51 is located on the bottom wall of the pressure plate 21. When the pressure plate 21 moves vertically downward, the clamping assembly 51 is used to fix the position of the control arm body 4 in the processing groove 3. The punching assembly 52 is located in the base 1, and the punching assembly 52 is used to punch the control arm body 4 in the processing groove 3. Two groups of second control cavities 6 are respectively located on the outside of the processing groove 3 inside the base 1. The side wall of the second control cavity 6 is provided with a second through hole 61 connected to the processing groove 3. A deburring mechanism 7 is provided in the second control cavity 6. The deburring mechanism 7 includes a grinding plate 71, a positioning assembly 72 and an adjustment assembly 73. The positioning assembly 72 is located in the second control cavity 6 and is connected to the grinding plate 71. The positioning assembly 72 is used to adjust the position of the grinding plate 71 in the second control cavity 6. The adjusting assembly 73 is connected to the positioning assembly 72. The adjusting assembly 73 is used to adjust the relative positions of multiple groups of grinding plates 71 by cooperating with the positioning assembly 72.

[0028] Initially, the positioning assembly 72 supports and positions the grinding disc 71 in the second control chamber 6, places the control arm body 4 to be processed in the processing groove 3, and the hydraulic cylinder 2 pushes the pressure plate 21 to move vertically downward. During the downward movement of the pressure plate 21, the clamping assembly 51 can stably fix the control arm body 4 in the processing groove 3, and the pressure plate 21 continues to move downward. The punching assembly 52 can synchronously punch both ends of the control arm body 4. After punching is completed, the hydraulic cylinder 2 controls the pressure plate 21 to move vertically upward a certain distance. At this time, the punching assembly 52 and the control arm body 4 are separated from each other, and the clamping assembly 51 continues to squeeze and fix the control arm body 4. The positioning assembly 72 pushes the grinding disc 71 toward the processing groove 3. The positioning assembly 72 cooperates with the adjustment assembly 73 to synchronously adjust the relative distance between the multiple groups of grinding discs 71, thereby controlling the grinding discs 71 to pass through the second through hole 61 and move into the processing groove 3. Some grinding discs 71 further pass through the holes on the surface of the control arm body 4. Multiple groups of grinding discs 71 are located on both sides of the holes on the surface of the control arm body 4. The positioning assembly 72 controls the rotation of the grinding discs 71. During rotation, the grinding discs 71 can effectively grind and deburr both sides of the hole on the surface of the control arm body 4, effectively improving the punching effect of the control arm body 4. After grinding is completed, the positioning assembly 72 cooperates with the adjustment assembly 73 to control the multiple groups of grinding discs 71 to move back into the second control chamber 6. The hydraulic cylinder 2 pulls the pressing plate 21 to move vertically upward, and the clamping assembly 51 releases the restriction on the control arm body 4 , so that the staff can easily take out the punched control arm body 4 from the processing groove 3 .

[0029] like Figure 1 、 Figure 2 As shown, as a preferred embodiment of the present invention, the clamping assembly 51 includes two groups of relatively distributed receiving grooves 511 opened upward from the bottom wall of the pressure plate 21, and an extrusion plate 512 is slidably installed in the receiving groove 511. The bottom end of the extrusion plate 512 extends to the outside of the receiving groove 511, and a clamping groove 514 is opened at the bottom end of the extrusion plate 512. An extrusion spring 513 is fixedly installed on the top wall of the receiving groove 511, and the telescopic end of the extrusion spring 513 is connected to the extrusion plate 512.

[0030] When the pressure plate 21 moves vertically downward, it drives the extrusion plate 512 to move downward synchronously. After the clamping groove 514 at the bottom end of the extrusion plate 512 is engaged with the control arm body 4, the pressure plate 21 continues to move downward. At this time, the extrusion plate 512 moves relatively upward in the storage groove 511, and the extrusion spring 513 is continuously pressurized. The extrusion plate 512 continues to apply pressure to the control arm body 4, which can conveniently fix the control arm body 4 in the processing groove 3.

[0031] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 8 、 Figure 9 As shown, as a preferred embodiment of the present invention, the punching assembly 52 includes two groups of first control cavities 522 opened inside the base 1 and located respectively on the inner side of the processing groove 3, the side wall of the first control cavity 522 is provided with a first through hole 525 connected to the processing groove 3, and the two opposite side walls of the processing groove 3 are respectively fixedly installed with a limit ring 521 that cooperates with the control arm body 4, a sliding block 523 is slidably installed in the first control cavity 522, and a stamping column 524 is fixedly installed on the side wall of the sliding block 523, a vertical hole 526 is opened in the middle of the base 1, a telescopic column 528 is slidably installed in the vertical hole 526, a positioning spring 527 is fixedly installed at the bottom of the vertical hole 526, the telescopic end of the positioning spring 527 is connected to the bottom end of the telescopic column 528, and a push rod 529 is rotatably installed on the side wall of the telescopic column 528, and the push rod 529 extends into the first control cavity 522 at one end away from the telescopic column 528 and is rotatably connected to the sliding block 523.

[0032] The positioning spring 527 supports and positions the telescopic column 528 in the vertical hole 526. The top of the telescopic column 528 extends above the base 1. The pressure plate 21 continues to move downward. The pressure plate 21 squeezes the telescopic column 528 and pushes the telescopic column 528 toward the vertical hole 526. The telescopic column 528 cooperates with the push rod 529 to push the sliding blocks 523 on both sides to move synchronously in the first control cavity 522. The sliding block 523 pushes the stamping column 524 to move toward the processing groove 3. The stamping column 524 can automatically punch the control arm body 4 in the processing groove 3. After punching is completed, the hydraulic cylinder 2 pulls the pressure plate 21 to move vertically upward. At this time, the positioning spring 527 pushes the telescopic column 528 to move vertically upward in the vertical hole 526. The telescopic column 528 cooperates with the push rod 529 to pull the sliding block 523 to move in the opposite direction in the first control chamber 522. The sliding block 523 drives the stamping column 524 to move as a whole into the first control chamber 522. At this time, the stamping column 524 and the control arm body 4 are separated from each other.

[0033] like Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7As shown, as a preferred embodiment of the present invention, the positioning assembly 72 includes an electric telescopic rod 721 fixedly installed at one end of the second control chamber 6 away from the processing groove 3, the telescopic end of the electric telescopic rod 721 is fixedly connected to a supporting plate 722, a motor 723 is fixedly installed on the surface of the supporting plate 722, the output shaft of the motor 723 is fixedly installed with a supporting column 724, two rows of positioning rods 725 are rotatably installed on the surface of the supporting column 724, each row of positioning rods 725 is provided with multiple groups and distributed in a ring around the supporting column 724, the grinding plate 71 is fixedly installed on the end of the positioning rod 725 away from the supporting column 724, a support spring 726 is fixedly installed on the surface of the supporting column 724, and the telescopic end of the support spring 726 is connected to the positioning rod 725.

[0034] The support spring 726 supports and positions the positioning rod 725 on the surface of the bearing column 724 . The positioning rod 725 maintains an inclined state on the surface of the bearing column 724 . The positioning rod 725 supports and positions the grinding sheet 71 . When it is necessary to deburr the hole on the surface of the control arm body 4, the electric telescopic rod 721 pushes the carrying plate 722 to move in the second control chamber 6, and the carrying plate 722 drives the motor 723 and the grinding disc 71 to move synchronously. The carrying column 724 drives the grinding disc 71 to move toward the processing groove 3. At the same time, the adjusting component 73 can control the positioning rod 725 to rotate toward the surface of the supporting column 724, and multiple groups of grinding discs 71 can be easily passed through the second through hole 61, and further control a row of positioning rods 725 and the grinding disc 71 on the surface of the supporting column 724 to pass through the hole on the surface of the control arm body 4. At this time, the two groups of grinding discs 71 are respectively on both sides of the hole, and the supporting spring 726 applies thrust to the positioning rod 725, and the grinding disc 71 fits against the two sides of the hole. The motor 723 drives the carrying column 724 to rotate, and the carrying column 724 drives the grinding disc 71 to rotate synchronously, and the grinding disc 71 can efficiently grind the burrs on both sides of the hole. After grinding is completed, the electric telescopic rod 721 drives the supporting plate 722 to move in the opposite direction. At this time, the supporting column 724 drives the grinding disc 71 to move into the second control chamber 6. The adjustment component 73 adjusts the position of the positioning rod 725 and the grinding disc 71 again to facilitate multiple groups of grinding discs 71 to pass through the second through hole 61.

[0035] like Figure 2 、 Figure 5 、 Figure 6 、 Figure 7As shown, as a preferred embodiment of the present invention, the adjustment component 73 includes a wire groove 731 opened inside the supporting column 724, and the two ends of the wire groove 731 extend to the surface of the supporting column 724 respectively. A control rope 732 is fixedly installed on the surface of the positioning rod 725, and the end of the control rope 732 away from the positioning rod 725 passes through the wire groove 731 and is fixedly installed with a positioning ring 733. The positioning ring 733 is made of magnetic material and is sleeved on the surface of the supporting column 724. A plurality of groups of brackets 734 are fixedly installed on the inner wall of the second control chamber 6, and the plurality of groups of brackets 734 are jointly fixedly installed with a magnetic ring 735.

[0036] When the supporting column 724 drives the grinding sheet 71 to move toward the processing groove 3, it drives the positioning ring 733 to move synchronously. When the positioning ring 733 moves to the inner side of the magnetic ring 735, the magnetic ring 735 is connected to the positioning ring 733 as a whole through magnetic attraction, and the supporting column 724 drives the grinding sheet 71 to continue to move. The positioning ring 733 cooperates with the control rope 732 to pull the positioning rod 725 toward the surface of the supporting column 724. At this time, the grinding sheet 71 moves synchronously toward the surface of the supporting column 724. Multiple groups of grinding sheets 71 can be easily passed through the second through hole 61, and a row of positioning rods 725 on the surface of the supporting column 724 moves to the other side of the hole. At this time, the positioning ring 733 and the magnetic ring 735 are separated from each other, and the support spring 726 applies a thrust to the positioning rod 725, and the grinding sheet 71 fits against both sides of the hole.

[0037] like Figure 6 、 Figure 7 As shown, as a preferred embodiment of the present invention, a retaining ring 8 is fixedly installed on the surface of the supporting column 724 through a support rod, and the retaining ring 8 is sleeved on the outside of the positioning rod 725. A plurality of groups of baffles 9 are fixedly installed on the surface of the retaining ring 8, and the two groups of baffles 9 are respectively located on both sides of the positioning rod 725.

[0038] The retaining ring 8 limits the rotation range of the positioning rod 725. The positioning rod 725 is located between the two sets of baffles 9. When the supporting column 724 drives the positioning rod 725 to rotate, the baffles 9 and the retaining ring 8 cooperate with each other, which can effectively improve the stability of the positioning rod 725.

[0039] like Figure 2 、 Figure 4 As shown in FIG. 1 , as a preferred embodiment of the present invention, a guide groove 10 extending downward to the outside of the base 1 is formed on the bottom wall of the second control cavity 6 .

[0040] The working principle of the present invention is: the control arm body 4 to be processed is placed in the processing groove 3, the hydraulic cylinder 2 pushes the pressure plate 21 to move vertically downward, and when the pressure plate 21 moves vertically downward, it drives the extrusion plate 512 to move downward synchronously. After the clamping groove 514 at the bottom end of the extrusion plate 512 is engaged with the control arm body 4, the pressure plate 21 continues to move downward. At this time, the extrusion plate 512 moves relatively upward in the storage groove 511, and the extrusion spring 513 is continuously pressurized. The extrusion plate 512 continuously applies pressure to the control arm body 4, which can conveniently fix the control arm body 4 in the processing groove 3. The pressure plate 21 continues to move downward, squeezing the telescopic column 528 and pushing it toward the vertical hole 526. The telescopic column 528 cooperates with the push rod 529 to push the sliding blocks 523 on both sides to move synchronously within the first control chamber 522. The sliding blocks 523 push the punching column 524 toward the processing groove 3. The punching column 524 can automatically punch the control arm body 4 within the processing groove 3. After punching is completed, the hydraulic cylinder 2 pulls the pressure plate 21 to move vertically upward. At this time, the positioning spring 527 pushes the telescopic column 528 to move vertically upward within the vertical hole 526. The telescopic column 528 cooperates with the push rod 529 to pull the sliding block 523 to move in the opposite direction within the first control chamber 522. The sliding block 523 drives the punching column 524 to move as a whole into the first control chamber 522. At this time, the punching column 524 and the control arm body 4 are separated from each other.

[0041] When it is necessary to deburr the hole on the surface of the control arm body 4, the electric telescopic rod 721 pushes the carrying plate 722 to move in the second control chamber 6, and the carrying plate 722 drives the motor 723 and the grinding disc 71 to move synchronously. The carrying column 724 drives the grinding disc 71 to move toward the processing groove 3. At the same time, the carrying column 724 drives the grinding disc 71 to move toward the processing groove 3 and drives the positioning ring 733 to move synchronously. When the positioning ring 733 moves to the inside of the magnetic ring 735, the magnetic ring 735 is connected to the positioning ring 733 as a whole through the magnetic attraction force, and the bearing The support column 724 drives the grinding disc 71 to continue moving. The positioning ring 733 cooperates with the control rope 732 to pull the positioning rod 725 toward the surface of the support column 724. At this time, the grinding disc 71 moves synchronously toward the surface of the support column 724. Multiple groups of grinding discs 71 can be easily passed through the second through hole 61. The row of positioning rods 725 on the surface of the support column 724 moves to the other side of the hole. At this time, the positioning ring 733 and the magnetic ring 735 separate from each other, and the support spring 726 applies a thrust to the positioning rod 725, causing the grinding disc 71 to fit against both sides of the hole. The motor 723 drives the support column 724 to rotate, and the support column 724 drives the grinding disc 71 to rotate synchronously. The grinding disc 71 can effectively grind the burrs on both sides of the hole. After grinding is completed, the electric telescopic rod 721 drives the supporting plate 722 to move in the opposite direction. At this time, the supporting column 724 drives the grinding disc 71 to move into the second control chamber 6, and adjusts the position of the positioning rod 725 and the grinding disc 71 again to facilitate multiple groups of grinding discs 71 to pass through the second through hole 61.

[0042] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
