Description

Technical Field

[0001] This application relates to the technical field of automotive parts manufacturing, and in particular to a processing mold for automotive seat components with feeding detection. Background Technology

[0002] In the production of car seats, progressive dies are typically used to process the workpiece. A progressive die is a multi-station stamping die that can complete multiple different stamping operations in one stroke of a press.

[0003] Currently, robotic arms are typically used to transfer automotive parts to be processed. The robotic arm clamps the workpiece from the previous progressive die stamping station to the next progressive die stamping station. At this time, the upper and lower dies of the progressive die at the next station close to perform stamping processing on the workpiece.

[0004] Regarding the aforementioned technologies, the inventors believe that during the transportation process of the continuous mold, sometimes the upper and lower molds close before the robotic arm has finished loading the workpiece, which affects the processing efficiency of automotive parts. Utility Model Content

[0005] In order to enable the inspection of workpiece loading and improve the processing efficiency of automotive seat parts, this application provides an automotive seat component processing mold with loading inspection.

[0006] The technical solution provided in this application for a processing mold for automotive seat components with feeding detection is as follows:

[0007] A processing mold for automotive seat components with feeding detection includes a lower mounting block, a lower mold, and a detection assembly. The lower mold is connected to the top surface of the lower mounting block, and the detection assembly is disposed on the top surface of the lower mounting block. The detection assembly includes a detection vertical rod, a detection rotating rod, a rotating shaft, and a proximity switch. A set of detection assemblies is disposed on each diagonal side of the lower mold. The detection vertical rod is vertically disposed at the edge of the lower mold. A rotating groove is formed vertically on the side of the detection plate closest to the lower mold. The rotating shaft is disposed at the bottom of the rotating groove, and the detection rotating rod is disposed in the rotating groove. A rotating block is disposed on the bottom side of the detection rotating rod away from the lower mold. The rotating block is rotatably connected to the rotating shaft. In its natural state, the top end of the detection rotating rod extends into the rotating groove towards the lower mold. The proximity switch is disposed on the vertical sidewall of the detection vertical rod away from the lower mold. When the detection rotating rod rotates into the rotating groove, the proximity switch approaches the detection rotating rod and receives an electrical signal.

[0008] By adopting the above technical solution, the robotic arm places the workpiece on the lower mold, and the workpiece presses against two detection rotating rods. The top of the detection rotating rods rotates to a position close to the proximity switch. At this time, the proximity switch receives an electrical signal, indicating that the workpiece loading operation has been completed. Through the cooperation of the lower mounting block, lower mold, and detection components, the system can effectively detect the loading of workpieces and improve the processing efficiency of automotive seat parts.

[0009] Optionally, a connecting block is provided on the side of the detection vertical rod away from the lower mold. When the detection rotating rod rotates to contact the connecting block, the proximity switch receives an electrical signal.

[0010] By adopting the above technical solution, the connecting block achieves the limitation of the rotation angle of the detection rod, thus avoiding excessive rotation of the detection rod.

[0011] Optionally, the detection rotating rod is provided with a first receiving hole on the side near the connecting block, and the connecting block is provided with a second receiving hole on the side near the detection rotating rod, corresponding to the position of the first receiving hole. A return spring is provided between the detection rotating rod and the connecting block, and the two ends of the return spring are respectively connected to the inner bottom wall of the first receiving hole and the inner bottom wall of the second receiving hole. In the natural state, the detection rotating rod extends out of the rotating groove under the action of the return spring.

[0012] By adopting the above technical solution, the reset spring realizes the automatic reset of the detection rod, so that the detection rod rotates to the side closer to the lower mold when there is no material, and the proximity switch moves away from the detection rod.

[0013] Optionally, the detection assembly further includes a fixed limiting rod, wherein one fixed limiting rod is vertically arranged on each of the two diagonally opposite sides of the lower mold, and the fixed limiting rod is disposed at the edge of the lower mold.

[0014] By adopting the above technical solution, two fixed limiting rods limit the workpiece, further improving the accuracy of workpiece loading.

[0015] Optionally, the top of both the fixed limiting rod and the limiting vertical rod are provided with placement chamfers, the placement chamfers are set towards the lower mold, and the top of the detection rotating rod is provided with a contact chamfer on the side close to the lower mold.

[0016] By adopting the above technical solution, the chamfered placement guides the workpiece and reduces the possibility of damage to the workpiece edge during loading. When lowering the workpiece, the workpiece edge contacts the chamfered contact point of the detection rotating rod, and the detection rotating rod rotates as the workpiece descends, facilitating workpiece placement.

[0017] Optionally, an abutment pad is provided on the side of the detection rotating rod near the lower mold.

[0018] By adopting the above technical solution, the setting of the abutment pad reduces the possibility of damage to the workpiece edge.

[0019] Optionally, the fixed limiting rod is provided with a clamping assembly, which includes a clamping slider and a clamping spring. A receiving groove is opened on the side of the fixed limiting rod near the lower mold. The clamping slider is slidably disposed in the receiving groove. The clamping spring is connected between the bottom wall of the receiving groove and the clamping slider. One end of the clamping slider extends out of the receiving groove under the action of the clamping spring. The top end of the clamping slider extending out of the receiving groove is provided with an abutting slope.

[0020] By adopting the above technical solution, the two clamping sliders clamp the workpiece under the action of the clamping springs, reducing the possibility of the workpiece wobbling on the lower die. When lowering the workpiece, the edge of the workpiece slides relative to the abutting inclined surface, thus pushing the clamping sliders.

[0021] Optionally, an adjusting plate is slidably disposed in the receiving groove, the adjusting plate is connected to one end of the clamping spring, and an adjusting element for adjusting the position of the adjusting plate is provided on the fixed limiting rod.

[0022] By adopting the above technical solution, the position of the adjusting plate in the receiving groove can be adjusted by turning the adjusting screw according to different processing needs, thereby adjusting the clamping strength of the clamping assembly.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Through the cooperation of the lower mounting block, lower mold and detection components, it can realize the loading and detection of workpieces and improve the processing efficiency of automotive seat parts;

[0025] 2. The clamping assembly reduces the possibility of workpiece wobbling on the lower die;

[0026] 3. The reset spring enables the automatic reset of the detection rod. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be further described in detail below. Embodiments of this application provide a processing mold for automotive seat components with feeding detection, which has the effect of realizing workpiece feeding detection and improving the processing efficiency of automotive seat parts.

[0034] Reference Figure 1-3 A processing mold for automotive seat components with feeding detection includes a lower mounting block 1, a lower mold 2, a fixing limit rod 3, a clamping assembly 4, and a detection assembly 5. Combined with... Figure 4 The lower mold 2 is mounted on the top surface of the lower mounting block 1.

A rotating groove 9 is vertically formed on the side of the detection vertical rod 51 closest to the lower mold 2, and the side of the detection vertical rod 51 furthest from the lower mold 2 is connected to the connecting block 52.

[0036] Reference Figure 2 and Figure 3 The bottom end of the detection rod 54, away from the lower mold 2, is connected to the rotating block 55. The rotating shaft 56 is located on the inner wall of the bottom end of the rotating groove 9, and the rotating block 55 is rotatably connected to the rotating shaft 56. A first receiving hole 541 is provided on the side of the detection rod 54 near the connecting block 52, and a second receiving hole 521 is provided on the side of the rotating block 55 near the detection rod 54. The first receiving hole 541 and the second receiving hole 521 are positioned correspondingly. A return spring 57 is located between the detection rod 54 and the connecting block 52. One end of the return spring 57 is connected to the inner bottom wall of the first receiving hole 541, and the other end is connected to the inner bottom wall of the second receiving hole 521. In its natural state, the top end of the detection rod 54 extends out of the rotating groove 9 under the action of the return spring 57. The fixed limiting rod 3 and the top of the detection vertical rod 51 near the lower mold 2 are both provided with placement chamfers 7, the top of the detection rotating rod 54 near the lower mold 2 is provided with contact chamfers 542, and the side of the detection rotating rod 54 near the lower mold 2 is provided with abutment pads 8.

[0037] Reference Figure 2 and Figure 3 The proximity switch 58 is located on the vertical side wall of the detection rod 51 away from the lower mold 2. When the detection rod 54 rotates under pressure to abut against the connecting block 52, the top of the detection rod 54 approaches the proximity switch 58, and the proximity switch 58 receives an electrical signal.

[0038] Reference Figure 4 and Figure 5The clamping assembly 4 is mounted on the fixed limiting rod 3. The clamping assembly 4 includes a clamping slider 45, an adjusting bolt 42, an adjusting plate 43, and a clamping spring 44. A receiving groove 31 is provided on the side of the fixed limiting rod 3 near the lower mold 2. The adjusting plate 43 is vertically slidably disposed in the receiving groove 31, with its side edge sliding against the inner wall of the receiving groove 31. The adjusting bolt 42 is threadedly connected to the side of the fixed limiting rod 3 away from the lower mold 2, and its end extends into the receiving groove 31 and is rotatably connected to the adjusting plate 43. The clamping slider 45 is slidably disposed in the receiving groove 31, located on the side of the adjusting plate 43 away from the adjusting screw. The clamping spring 44 is disposed between the adjusting plate 43 and the clamping slider 45, with one end connected to the adjusting plate 43 and the other end connected to the clamping slider 45. In its natural state, one end of the clamping slider 45 extends out of the receiving groove 31 under the action of the clamping spring 44. The top of the end of the clamping slider 45 that extends out of the receiving groove 31 is provided with a sliding slope 451.

[0039] Reference Figure 2 and Figure 3 When the workpiece is placed on the lower mold 2 under the gripper of the robotic arm, the workpiece presses against the top of the detection rod 54, causing the detection rod 54 to rotate away from the lower mold 2 until it abuts against the connecting block 52. At this point, the return spring 57 compresses and accumulates elastic potential energy. The connecting block 52 limits the rotation angle of the detection rod 54. The abutment pad 8 reduces the possibility of damage to the workpiece edge during lowering. The placement of the chamfer 7 and the contact chamfer 542 limit and guide the lower part of the workpiece, while also reducing the possibility of damage to the workpiece edge during lowering.

[0040] Reference Figure 3-5 When the workpiece is fully placed on the top surface of the lower mold 2, the detection rod 54 rotates to a position close to the proximity switch 58. The two proximity switches 58 receive electrical signals, indicating that the workpiece is in place and subsequent processing can proceed. After the workpiece is removed, the detection rod 54 resets under the action of the return spring 57. The two fixed limit rods 3 limit the workpiece, improving the positioning accuracy of the workpiece on the lower mold 2. When placing the workpiece, it contacts the sliding inclined surface 451 of the clamping slider 45 and slides relative to it. The clamping slider 45 moves towards the adjusting plate 43 under the push of the workpiece. The two clamping sliders 45 clamp the edges of the workpiece under the action of the clamping spring 44, reducing the possibility of the workpiece wobbling on the lower mold 2. To adjust the clamping strength according to different clamping strength requirements, the adjusting screw is turned, and the adjusting plate 43 slides in the receiving groove 31, thus adjusting the clamping strength.

[0041] The implementation principle of a car seat component processing mold with feeding detection in this embodiment is as follows: When the workpiece is placed on the lower mold 2 under the clamping of the robotic arm, the detection rotating rod 54 rotates away from the lower mold 2. When the workpiece is completely placed on the top surface of the lower mold 2, the detection rotating rod 54 rotates to a position close to the proximity switch 58. The proximity switch 58 receives an electrical signal, proving that the workpiece is in place. Two fixed limiting rods 3 limit the workpiece, improving the positioning accuracy of the workpiece on the lower mold 2. Two clamping sliders 45 clamp the edges of the workpiece, reducing the possibility of the workpiece shaking on the lower mold 2.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
