Description

Technical Field

[0001] The utility model relates to the technical field of automobile panel stamping processing, and specifically relates to an automatic positioning device for automobile panel stamping processing. Background Technique

[0002] In the process of automobile manufacturing, the stamping processing of automobile panels is a very crucial link. Automobile panels not only have strict requirements for appearance quality, but also their dimensional accuracy and shape accuracy directly affect the overall performance and safety of the automobile. The prerequisite for realizing high-precision stamping processing is to have a precise and reliable automatic positioning device, which can ensure the accuracy of the position of the sheet during the panel stamping process, reduce the rejection rate, and improve production efficiency.

[0003] Currently, when using a stamping device to stamp automobile parts, it is usually manually placed the material to be processed on the stamping equipment by workers, and this operation has potential safety hazards; to solve the above problems, reference can be made to a stamping positioning device for automobile parts disclosed in the prior art (Chinese Patent with application number CN202322941885.2 and application date October 31, 2023). By setting limit sleeves, T-shaped pressing rods and first return springs on both sides of the hydraulic telescopic cylinder, when the hydraulic telescopic cylinder stamps the sheet through the stamping head, the elastic downward pressure of the T-shaped pressing rod can be used to pre-fix the sheet, avoiding the problem that the sheet will be displaced due to lack of fixation during the stamping process and resulting in defective products. Secondly, by setting a blanking structure between the hydraulic telescopic cylinder and the stamping table, the hydraulic telescopic cylinder can also automatically blank the stamped sheet synchronously during the stamping process, simplifying the blanking process.

[0004] The above device can achieve the preliminary limit of the sheet, however, there are still obvious drawbacks in the subsequent feeding process. Due to the combined action of factors such as vibration during the feeding process, inertia of mechanical operation, and inertia of the sheet itself, it is very easy to cause the displacement of the limited object; once this displacement occurs, in the subsequent further processing links, such as precise stamping operations, the object cannot be accurately in the predetermined processing position, thus greatly increasing the risk of workpiece damage.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 - 6 , the present utility model provides the following technical solutions: an automatic positioning device for stamping and processing automotive panels.

[0026] Embodiment 1: To solve the problem that although the positioning devices on the current market can achieve the preliminary limit of the plate, there are still obvious drawbacks in the subsequent feeding process. Due to the combined effects of factors such as vibration during feeding, inertia of mechanical operation, and inertia of the plate itself, it is extremely easy for the limited objects to be displaced; once such displacement occurs, in subsequent further processing steps, such as precise stamping operations, the objects cannot be accurately in the predetermined processing position, thus greatly increasing the problem of workpiece damage. For reference, please refer to Appendix Figure 1 , Appendix Figure 2 , Appendix Figure 4 and Appendix Figure 5, including a fixed seat 1, a stamping die 2 is fixed at the top position of the fixed seat 1, a fixing plate 3 is fixed on the left side of the fixed seat 1, a hydraulic push rod 4 is fixed at the bottom position of the fixing plate 3, and the output end of the hydraulic push rod 4 is correspondingly directly below the stamping die 2; a placing table 10 is slidably arranged at the upper right end position of the fixed seat 1, an air conveying assembly 5 is fixed at the lower right end of the fixed seat 1, and the output end of the air conveying assembly 5 is connected to an air conveying assembly 5. Three groups are connected in the middle position of the air conveying assembly 5 through a three-way valve. Feeding mechanisms are arranged at the outer ends of the front and rear two groups of first conveying pipes 6. The arrangement of the feeding mechanisms realizes the feeding of the car panel on the placing table 10; the feeding mechanism includes an extension cylinder 8 slidably arranged at the outer end of the first conveying pipe 6. The inner wall position of the extension cylinder 8 is connected to the head end position of a return spring 7, and the tail end position of the return spring 7 is fixed at one end position of the first conveying pipe 6; the outer end position of the extension cylinder 8 is fixed at the outer end of a slider 9, and the top of the slider 9 is fixed at the bottom of the placing table 10. The outer side of the slider 9 is slidably arranged inside a chute 21. The placing table 10 and the inside of the chute 21 form a sliding structure through the slider 9.

[0027] When feeding the car panel shell, by continuously conveying gas to the positioned car panel shell, at this time the gas will continue to be conveyed through the first conveying pipe 6. The first conveying pipe 6 conveys gas to the inside of the first conveying pipe 6 and the extension cylinder 8, so that the extension cylinder 8 can move inside through the return spring 7, and the outer end of the extension cylinder 8 drives the placing table 10 to slide inside the chute 21 opened inside the fixed seat 1 through a positioning block 20. At this time, the second conveying pipe 12 extends through the telescopic pipe 11, so that the car panel shell placed on the top of the placing table 10 is conveyed to one side of the stamping die 2 at the horizontal position, which is convenient for the hydraulic push rod 4 to perform stamping processing on the stamping die 2 with the car panel shell placed on it.

[0028] Embodiment 2: In order to facilitate the limiting work of the car panel shell, reference can be made to Appendix Figure 1 - Appendix Figure 4 and Appendix Figure 6, the outer end of the first conveying pipe 6 in the middle is connected to one end of the telescopic pipe 11, the other end of the telescopic pipe 11 is connected to one end of the second conveying pipe 12, and the other end of the second conveying pipe 12 is arranged on one side of the positioning mechanism. The setting of the positioning mechanism enables the two groups of positioning blocks 20 to move relatively. The positioning mechanism includes a piston block 13 connected to the top position of the second conveying pipe 12. The top of the square piston block 13 is connected to the inner wall of the lifting screw block 15 through a connecting spring 14. The outer side of the lifting screw block 15 is screwed inside the spiral groove 16. The spiral groove 16 is opened inside the turntable 17. Oblique grooves 18 are opened on both sides of the top of the turntable 17. A matching block 19 is fitted inside the oblique groove 18. A positioning block 20 is fixed at the top position of the matching block 19; a guiding groove 1001 is penetrated and opened at the top of the placing table 10. The outer side of the matching block 19 is slidably arranged inside the guiding groove 1001. The matching block 19 forms a sliding structure between the inner parts of the oblique groove 18 and the guiding groove 1001; the pitch between the spiral groove 16 and the lifting screw block 15 is relatively large, and the turntable 17 is rotationally structured with the lifting screw block 15 through the spiral groove 16. The bottom of the turntable 17 is rotatably arranged at the inner position of the placing table 10; the elastic force of the connecting spring 14 is less than the elastic force of the return spring 7, and the outer wall of the piston block 13 is attached to the inner wall of the lifting screw block 15.

[0029] Place the automobile panel shell on the top position of the placing table 10. Subsequently, by starting the air conveying component 5, the output end of the air conveying component 5 conveys gas into the interior of the first conveying pipe 6. The first conveying pipe 6 will convey the gas into the interior of the telescopic pipe 11 and the second conveying pipe 12. The outer end of the second conveying pipe 12 is connected to the outer side of the piston block 13. Thus, the lifting screw block 15 arranged on the outer side of the piston block 13 will move in position. Since the lifting screw block 15 is screwed to the spiral groove 16, the lifting screw block 15 drives the turntable 17 to rotate at the bottom position of the placing table 10 through the spiral groove 16. Thus, the turntable 17 can drive the oblique groove 18 to rotate during the rotation process. At this time, the oblique groove 18 will provide a thrust force to one side of the matching block 19 during rotation. Thus, the matching block 19 and the positioning block 20 slide inside the sliding groove 21. The automobile panel shell is limited by the two groups of relatively moving positioning blocks 20, which facilitates the subsequent limiting process.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
