Description

Technical Field

[0001] This utility model relates to the field of automotive parts stamping fixtures, and more specifically, it relates to a fixture for stamping automotive parts. Background Technology

[0002] In the automotive manufacturing industry, stamping is one of the key technologies for producing various automotive parts. Through stamping, raw materials such as metal sheets can be processed into parts with complex shapes and precise dimensions to meet the assembly needs of different parts of the car.

[0003] However, there are some pressing problems in the existing automotive parts stamping process. On the one hand, after the stamping operation is completed, due to the significant frictional force between the stamping press and the automotive parts being processed, the stamped parts often rise along with the press as it completes the stamping action and rises. This upward movement not only causes positional shifts in the stamped parts, affecting subsequent assembly processes, but can also damage the surface of the parts, reducing product quality, increasing the defect rate, and ultimately raising production costs.

[0004] On the other hand, with the continuous development of the automotive industry, the shapes of automotive parts are becoming increasingly diverse, and irregularly shaped automotive parts are increasingly used in automobile manufacturing. However, most existing stamping fixtures have relatively simple designs and insufficient structural flexibility, making it difficult to quickly and effectively adjust and clamp them according to the unique shape and size of irregularly shaped automotive parts. This results in the fixtures being unable to provide stable and reliable clamping force when stamping irregularly shaped automotive parts, causing the parts to easily wobble or shift during the stamping process, seriously affecting stamping accuracy and product quality, and also limiting the widespread application of stamping technology in the production of irregularly shaped automotive parts.

[0005] Therefore, developing a stamping fixture for automotive parts that can effectively solve the problem of parts rising together after stamping and facilitate the clamping of irregularly shaped automotive parts is of great practical significance. Utility Model Content

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0029] Please see Figure 1-7 The present invention provides the following technical solution:

[0030] Example 1 includes a housing 1, a stamping seat 2 disposed on the top of the housing 1 for stamping automotive parts to be processed, and a worktable 3 disposed on the top of the housing 1 and located below the stamping seat 2. The automotive parts stamping fixture also includes an adjusting abutment mechanism 4. The adjusting abutment mechanism 4 is disposed on the top of the worktable 3 and includes a displacement part 41 and a flipping abutment part 42. The displacement part 41 is slidably disposed on the top of the worktable 3, and multiple displacement parts 41 are used to clamp the outer side of the automotive parts to be processed. The flipping abutment part 42 is rotatably disposed on the top of the displacement part 41. When multiple displacement parts 41 respectively contact the automotive parts to be processed, the flipping abutment part 42 is flipped and abuts against the top of the automotive parts to be processed.

[0031] Specifically, the top of the housing 1 is equipped with a stamping machine for driving the stamping base 2 to move vertically downwards. When the stamping machine is started, it can drive the stamping base 2 to descend and rise. The top of the worktable 3 is provided with a drop groove for the waste material to fall off after stamping. First, the automotive parts to be processed are placed between the top of the worktable 3 and multiple displacement parts 41 by means of a robotic arm. Then, the multiple displacement parts 41 slide until one of the displacement parts 41 contacts and clamps the automotive parts to be processed, and then continues to move, and then stops moving. At this time, the flipping abutment part 42 is in a flipped state close to the automotive parts to be processed, until the flipping abutment part 42 completely abuts against the top of the automotive parts to be processed. At this time, the other displacement parts 41 that are not in contact with the automotive parts to be processed continue to move, thereby clamping different gears and irregularly shaped automotive parts. At the same time, when the displacement parts 41 come into contact with the automotive parts to be processed, they can drive the flipping abutment parts 42 to fix the top of the automotive parts to be processed. This can effectively prevent the automotive parts to be processed from loosening and shifting due to the friction generated by the stamping contact after the stamping seat 2 stamps the automotive parts to be processed.

[0032] See Figure 4 and Figure 5 The adjusting abutment mechanism 4 also includes a sliding part 43 and a guide part 44; the sliding part 43 has multiple sliding parts that are slidably disposed on the top of the worktable 3, and the top of the worktable 3 has multiple stroke grooves for the sliding part 43 to slide; the guide part 44 is slidably disposed on the side of the sliding part 43, and one end of the guide part 44 is fixed to the displacement part 41, and the middle part of the sliding part 43 has a stroke chamber for the guide part 44 to slide, so that when the sliding part 43 moves, it can drive the sliding part 43 and the displacement part 41 to move synchronously.

[0033] Specifically, when the automotive parts to be processed are placed on the top of the worktable 3 and located between multiple displacement parts 41, the sliding part 43 first moves along multiple stroke grooves opened on the top of the worktable 3 towards the automotive parts to be processed. When the sliding part 43 slides, it can drive the guide part 44 and the displacement part 41 to move synchronously until the displacement part 41 contacts the automotive parts to be processed, thus achieving clamping.

[0034] See Figures 4-6 The adjusting abutment mechanism 4 also includes a return spring 45; the return spring 45 is disposed on the outside of the guide portion 44, one end of the return spring 45 is fixed to the sliding portion 43, and the other end of the return spring 45 is fixed to the displacement portion 41. When the displacement portion 41 and the guide portion 44 slide toward the sliding portion 43, the return spring 45 is in a compressed state.

[0035] Specifically, when the displacement part 41 contacts the automotive part to be processed, the sliding part 43 and the displacement part 41 continue to move. In this state, the guide part 44 and the displacement part 41 can keep the return spring 45 in a compressed state. When the displacement part 41 is not in contact with the automotive part to be processed, the return spring 45 releases and pushes the displacement part 41 and the guide part 44 to slide away from the sliding part 43, thereby resetting the displacement part 41.

[0036] See Figure 5 and Figure 6 The adjusting abutment mechanism 4 also includes a positioning shaft 46 and a hinge rod 47; the positioning shaft 46 has multiple shafts and is respectively disposed on the top of the sliding part 43; the hinge rod 47 is rotatably disposed outside the positioning shaft 46, one end of the hinge rod 47 is rotatably connected to the positioning shaft 46, and the other end of the hinge rod 47 is rotatably connected to the flipping abutment part 42. When the displacement part 41 and the guide part 44 slide away from the sliding part 43, the hinge rod 47 tilts and drives the flipping abutment part 42 to be in a flipped state close to the sliding part 43.

[0037] Specifically, when the displacement part 41 contacts the automotive part to be processed and continues to move, the hinge rod 47 can rotate the flipping abutment part 42, which is rotatably mounted on top of the displacement part 41, towards the automotive part to be processed, until the flipping abutment part 42 abuts against the top of the automotive part to be processed. After the automotive part is stamped and the sliding part 43 drives the displacement part 41 to slide away from the automotive part, the return spring 45 is released and pushes the displacement part 41 to slide. At this time, the hinge rod 47 can drive the flipping abutment part 42 back to its initial position.

[0038] See Figure 4 The adjusting abutment mechanism 4 also includes a mounting plate 48 and a multi-stage telescopic cylinder 49; there are multiple mounting plates 48 respectively disposed at the bottom of the worktable 3, and the multiple mounting plates 48 are all located on the outside of the sliding part 43, and the multiple mounting plates 48 are arranged in a circular array; there are multiple multi-stage telescopic cylinders 49 respectively disposed at the top of the mounting plate 48, and the output ends of the multiple multi-stage telescopic cylinders 49 are all fixed to the side of the sliding part 43, and when the multi-stage telescopic cylinders 49 are activated, they can drive the sliding part 43 to move.

[0039] Specifically, when multiple sliding parts 43 need to be driven to slide, multiple telescopic cylinders are first activated, which in turn drives the sliding parts 43 to slide. By controlling each multi-stage telescopic cylinder 49, the different shaped automotive parts can be clamped.

[0040] See Figure 7The adjusting abutment mechanism 4 also includes a flexible support part 491; the flexible support part 491 has multiple parts and is slidably disposed on the top of the worktable 3, and the multiple flexible support parts 491 are all located below the stamping seat 2, and the multiple flexible support parts 491 are used to support the bottom of the automotive parts to be processed.

[0041] Specifically, in its initial state, the flexible support portion 491 can lift the automotive parts to be processed upwards. The flexible support portion 491 incorporates a spring assembly to achieve elastic cushioning characteristics; and the flexible support portion 491 is preferably made of rubber, which further enhances its cushioning performance and adaptability. When the stamping seat 2 performs a stamping operation on the automotive parts to be processed, the flexible support portion 491 can play a cushioning role, effectively buffering the stamping force generated by the stamping seat 2, thereby protecting the automotive parts to be processed from excessive impact force and ensuring the stability and safety of the stamping process.

[0042] See Figure 7 The adjusting abutment mechanism 4 also includes a buffer cylinder 492; there are multiple buffer cylinders 492 respectively disposed at the bottom of the worktable 3, and the output ends of the multiple buffer cylinders 492 are connected to multiple flexible support parts 491. When the buffer cylinders 492 are activated, they can drive the multiple flexible support parts 491 to move in an upward or downward motion state.

[0043] Specifically, after the stamping contact, the buffer cylinder 492 is activated and pushes the flexible support part 491 into an upward sliding state, thereby quickly lifting the stamped automotive parts and making it easier to pick up the stamped automotive parts.

[0044] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
