Description

Technical Field

[0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to an automatic induction positioning mechanism for a mold. Background Art

[0002] Traditional body parts production typically utilizes manual production lines within the stamping workshop to produce longitudinal beam stampings. However, due to the need for increased production capacity, the molds originally produced on the manual lines need to be transferred to automated production lines. This requires the existing molds to be modified to accommodate automated production. The molds must be designed and equipped with automated material inspection sensors to ensure that material loading is in place. This sensor, which primarily functions to confirm material loading is in place, allows production to begin.

[0003] Because the molds produced on the original manual production line weren't designed with this factor in mind, there was no space on the mold's lower mold surface to install a material detection sensor. To meet the stamping process requirements of automated production and prevent tooling accidents caused by improper loading, a material detection sensor needed to be installed on the existing mold surface. However, given the complex shapes and large curves of longitudinal beam stamping parts, and the relatively narrow mold surface, positioning based solely on part shape would not meet the requirements of automated production. The shape positioning accuracy was low, which easily led to improper loading of parts.

[0004] It is necessary to design an automated material inspection sensing and positioning mechanism with both positioning and sensing functions. During the production of stamping parts, the workpiece is placed on one end of the "lever" and the other end is tilted to maintain a sensing distance from the automated sensor. At the same time, the positioning block of this mechanism plays a role in positioning the stamping parts, avoiding technical problems such as inadequate loading of stamping parts and inability to install sensors. Summary of the Invention

[0009] Further, the positioning mechanism further includes a limiting frame and a slide rail. Both the limiting frame and the slide rail are installed on the fixed plate. A first transmission rod is provided inside the limiting frame, and a second transmission rod is provided on the slide rail. An upper part of one end of the positioning lever away from the mold body is provided with a chute.

[0010] Further, the first transmission rod passes through the limiting frame and is slidably engaged with the limiting frame. Gear teeth are arrayed on one side end of the first transmission rod extending out of the limiting frame. The second transmission rod is slidably engaged with the slide rail. Gear teeth are arrayed on the upper end of the second transmission rod and are arranged on one side end close to the inside of the slide rail.

Detailed Description of the Invention

[0023] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0024] The present invention improves the installation method of the existing automatic sensor, manufactures an L-shaped installation base and fixes it on the lower die body of the mold; uses the "lever" principle, and according to the shape of the surface of the longitudinal beam type stamping part, the length of the stamping part, and the feeding direction, manufactures a mold automatic sensing and positioning mechanism. When producing the stamping part, after the part is placed on one end face of the "lever", the other end face tilts up to keep an induction distance from the automatic sensor. At the same time, the positioning block of this mechanism plays a role in positioning the stamping part, avoiding the occurrence of tooling accidents caused by the problem of the stamping part being not in place during feeding.

[0025] The present invention discloses a mold automatic sensing and positioning mechanism, such asFigure 1 As shown in the figure, the automatic induction positioning mechanism includes a mold body 1. On one side of the mold body 1, there is a fixedly connected mounting base 2. On the mounting base 2, there is a detachable first mounting plate 3. The first mounting plate 3 is detachably connected to the mounting base 2 through bolts and gaskets. At the upper end of the first mounting plate 3, there is a second mounting plate 5 for mounting an inductor 7. On the mounting base 2, there is also a fixedly connected fixing plate 4. The fixing plate 4 is arranged at one end of the side close to the mounting base 2. The fixing plate 4 is used for mounting a limit frame 11 and a slide rail 15. The fixing plate 4 is located on one side of the first mounting plate 3 and is outside the sensing area of the inductor 7.

[0026] The second mounting plate 5 is provided with mounting holes for mounting the inductor 7. The inductor 7 passes through the mounting holes. The inductor 7 is arranged on the second mounting plate 5 through two nuts. On the first mounting plate 3, there is also a positioning mechanism. The positioning mechanism is located between the fixing plate 4 and the second mounting plate 5. The positioning mechanism includes a positioning plate 6. As Figure 2 shown in the figure, the positioning plate 6 is arranged on the first mounting plate 3. On the positioning plate 6, there is a positioning lever 8 rotatably connected. The positioning lever 8 is rotatably connected to the positioning plate 6 through a rotating shaft.

[0027] At one end of the positioning lever 8 close to the mold body 1, there is a lever pressing plate. In the present invention, the shape of the positioning lever 8 is not specifically limited. It is only required that under the action of its own gravity (without applying any external force), one end of the positioning lever 8 close to the mold body 1 can be lifted, and the other end away from the mold body 1 can fall. Exemplarily, the width of one end of the positioning lever 8 close to the mold body 1 is smaller than that of the other end away from the mold body 1, so that under the action of its own gravity, one end of the positioning lever 8 close to the mold body 1 is lifted, and the other end away from the mold body 1 falls.

[0028] At one end of the mold body 1, there is a positioning hole 9. The positioning hole 9 is located in the middle of the mold body 1. When the workpiece to be punched is placed on the mold body 1, one end edge of the workpiece to be punched will press down the positioning lever 8. One end of the positioning lever 8 close to the mold body 1 rotates downward, and the other end away from the mold body 1 rotates upward until the workpiece to be punched is in close contact with the mold. At this time, one end of the positioning lever 8 close to the mold body 1 is placed in the positioning hole 9, and the other end is lifted to block the sensing end of the inductor 7. After the inductor 7 is blocked, it transmits an electrical signal to the control system, and the control system controls the mold to perform a punching action.

[0029] The upper part of one end of the positioning lever 8 away from the mold body 1 is provided with a fixedly connected sliding groove 10. The positioning mechanism further includes a limiting frame 11 and a sliding rail 15. The limiting frame 11 and the sliding rail 15 are both installed on the fixing plate 4 through connecting rods. A first transmission rod 12 is arranged in the limiting frame 11. The first transmission rod 12 passes through the limiting frame 11 and is in sliding fit with the limiting frame 11. The end of one side of the first transmission rod 12 extending out of the limiting frame 11 is provided with gear teeth distributed in an array. The lower end of the first transmission rod 12 is placed in the sliding groove 10 and is in sliding fit with the sliding groove 10. A second transmission rod 22 is arranged on the sliding rail 15. The second transmission rod 22 can slide in the sliding rail 15. The upper end of the second transmission rod 22 is provided with gear teeth distributed in an array. The gear teeth are arranged close to one end side placed in the sliding rail 15. The other end of the second transmission rod 22 is provided with a support plate 16 for locking the positioning pressing plate 21.

[0030] The fixing plate 4 is further provided with a first gear 13 and a second gear 14. The first gear 13 and the second gear 14 are rotatably connected to the fixing plate 4 through a rotating shaft. The first gear 13 and the second gear 14 are fixedly arranged on the rotating shaft. The first gear 13 is in cooperation with the gear teeth on the first transmission rod 12, and the second gear 14 is in cooperation with the gear teeth on the second transmission rod 22. The first gear 13 and the second gear 14 rotate coaxially.

[0031] One side of the mold body 1 is provided with a fixedly connected support rod 24. The support rod 24 is arranged close to one end of the mold body 1. The support rod 24 is located on one side of the fixing plate 4. Two limiting plates 17 are arranged on the end face of the support rod 24 facing the mold body 1. A limiting rod 18 and an L-shaped connecting rod 19 are arranged between the limiting plates 17. The limiting rod 18 is fixedly connected to the limiting plates 17. The limiting rod 18 passes through the L-shaped connecting rod 19 and is in sliding fit with the L-shaped connecting rod 19. One end of the L-shaped connecting rod 19 is provided with a positioning pressing plate 21. The height of the positioning pressing plate 21 in the vertical direction is higher than that of the support plate 16.

[0032] An elastic member 20 is arranged between the L-shaped connecting rod 19 and the limiting plate 17 with a higher vertical height. The elastic member 20 is sleeved on the limiting rod 18. One end of the elastic member 20 is fixedly connected to the L-shaped connecting rod 19, and the other end is fixedly connected to the upper limiting plate 17. The L-shaped connecting rod 19 and the upper limiting plate 17 are connected through the elastic member 20.

[0033] In some embodiments of the present invention, the positioning lever 8 is further provided with a counterweight assembly 23, as Figure 3 shown. The counterweight assembly 23 is arranged at one end of the positioning lever 8 away from the mold body 1. Arranging the counterweight assembly 23 can ensure that one end of the positioning lever 8 away from the mold body 1 is heavier than the end close to the mold body 1. In the present invention, the counterweight assembly 23 is not specifically limited as long as the above function can be achieved; for example, the counterweight assembly 23 can be a counterweight screw, a bolt, a nut, etc.

[0034] The working principle of the present invention is as follows: first, the workpiece to be stamped is placed on the mold body 1, and one end of the workpiece to be stamped presses the lever pressure plate downward. The slide 10 rotates upward following the positioning lever 8, and the slide 10 pushes the first transmission rod 12 upward. The first transmission rod 12 moves upward to drive the first gear 13 and the second gear 14 to rotate. The second gear 14 drives the second transmission rod 22 to move toward the side away from the mold body 1, and the support plate 16 is pulled away from the lower part of the positioning pressure plate 21. The positioning pressure plate 21 and the L-shaped connecting rod 19 move downward under the action of the elastic member 20 and press the workpiece to be stamped on the mold body 1. At this time, one end of the positioning lever 8 Move to the sensing area of the sensor 7, and the sensor 7 senses the positioning lever 8 and transmits an electrical signal to the control system. The control system controls the mold to perform the stamping action to complete the stamping; remove the stamping part. During this process, one end of the stamping part pushes the positioning pressure plate 21 and the L-shaped connecting rod 19 upward, and the positioning lever 8 rotates in the opposite direction under the action of gravity, driving the first gear 13 and the second gear 14 to rotate in the opposite direction. The support plate 16 moves toward the mold body 1 to the bottom of the positioning pressure plate 21, and the positioning lever 8 leaves the sensing area of the sensor 7. At this time, the stamping part is completely pulled out, and the position of the positioning pressure plate 21 is locked; this cycle is repeated.
