Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing equipment technology, and in particular to a punching protection mechanism for automotive parts. Background Technology

[0002] In the automotive manufacturing industry, punching is an indispensable and crucial process in the forming and processing of metal and non-metal parts. Punching is typically accomplished using stamping equipment, which applies strong pressure to the parts through a die, causing them to separate and form holes.

[0003] In actual production, automotive parts, especially body panels and structural components, often exhibit complex three-dimensional curved surfaces and irregular contours. Existing general-purpose stamping equipment is equipped with simple clamping plates or vises designed for flat workpieces. When used to clamp these irregularly shaped automotive parts, the mismatch in contact surfaces often fails to provide stable and uniform clamping force, leading to workpiece displacement or vibration during stamping, severely impacting punching accuracy and product yield.

[0004] Meanwhile, the stamping process generates a large amount of metal scrap. In many existing work scenarios, this scrap typically falls directly to the bottom of the equipment or is blown onto the surrounding ground. This method not only creates a messy work environment and increases the difficulty of cleaning, but the flying, sharp scrap also poses a potential safety threat to on-site operators and precision equipment. Existing protective measures are often limited to simple barriers, which cannot effectively collect and manage the scrap in a closed manner.

[0005] Therefore, this utility model proposes a punching protection mechanism for automotive parts to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of unstable clamping of irregular automotive parts leading to low punching accuracy and random scattering of stamping waste causing environmental pollution and safety hazards in the existing automotive parts punching mechanism, this utility model aims to provide an automotive parts punching protection mechanism with improved structure that can effectively solve the above problems.

[0007] This utility model provides a punching protection mechanism for automotive parts, including a base, a punching head disposed above the base, and a drawer that can be pulled out and disposed inside the base; the mechanism also includes a clamping mechanism and a fixing mechanism disposed on the base.

[0008] The clamping mechanism includes a clamping assembly driven by a pneumatic cylinder, and the clamping assembly is provided with a clamping arm for clamping automotive parts.

[0009] Furthermore, the fixing mechanism includes an operating lever and a fixing head that is linked to the operating lever. The fixing head is used to selectively engage or disengage from the drawer to lock or unlock the drawer.

[0010] Preferably, the clamping mechanism further includes a fixed plate, a connecting pin, a rotating ring, and a linkage rod; the driving end of the pneumatic cylinder passes through the fixed plate and is connected to the connecting pin, the two ends of the connecting pin are rotatably connected to the rotating ring, one end of the linkage rod is rotatably connected to the rotating ring, and the other end is rotatably connected to the clamping assembly.

[0011] Preferably, the clamping mechanism includes two clamping components symmetrically arranged on the base to cooperate in clamping the automotive parts.

[0012] Preferably, the clamping assembly further includes a fixed base fixed to the base and a rotating shaft rotatably mounted on the fixed base; the clamping arm is fixedly connected to the rotating shaft, and the linkage rod is rotatably connected to the clamping arm to drive it to rotate around the rotating shaft.

[0013] Preferably, the stamping path of the stamping head is directly above the opening of the drawer.

[0014] Preferably, the fixing mechanism further includes a support fixed to the base and a spring disposed on the fixing head; the operating lever is rotatably connected around the support, and the spring is used to elastically push the fixing head toward the drawer to achieve locking.

[0015] Furthermore, the fixing mechanism also includes a housing and a limiting ring disposed inside the housing; the fixing head and the spring are both disposed inside the housing, and the limiting ring is located between the spring and the operating rod. When the operating rod rotates, it squeezes the spring through the limiting ring, causing the fixing head to overcome the elastic force of the spring and separate from the drawer.

[0016] Preferably, the clamping mechanism drives the clamping arm to perform closing clamping or opening release actions by retracting or extending the pneumatic cylinder.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem of fast, stable and multi-point positioning and clamping of irregularly shaped automotive parts by setting up a linkage clamping mechanism driven by a pneumatic cylinder. The mechanism drives multiple clamping arms to open and close synchronously through a linkage rod. It achieves the technical effects of automated clamping, accurate positioning and stable clamping force, and significantly improves the preparation efficiency and processing accuracy before punching.

[0018] 2. This utility model solves the problem of punching waste easily splashing and causing pollution and safety hazards in the prior art by setting a pull-out drawer inside the base and making the punch head face the drawer opening. It achieves the technical effect of collecting waste in a centralized manner and protecting the cleanliness of the environment, realizing the integration of punching and waste treatment.

[0019] 3. This utility model solves the safety problem of the waste drawer potentially sliding out unexpectedly during the stamping and vibration process by setting a manual fixing mechanism consisting of an operating lever, a spring, and a fixing head for the waste drawer. It achieves the technical effect of reliably locking the drawer during equipment operation and improving operational safety. The mechanism has a simple structure, is easy to operate, and is reliable in operation. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example:

[0023] Please refer to Figures 1 to 4This utility model provides a punching protection mechanism for automotive parts, which aims to solve the problems of unstable clamping of irregular automotive parts and easy splashing of punching waste polluting the environment in the prior art.

[0024] like Figure 1 As shown, the automotive parts punching protection mechanism includes a base 1, a punching head 2 disposed above the base 1, a clamping mechanism 3 disposed on the base 1, a fixing mechanism 4 disposed on the base 1, and a drawer 5 that can be pulled out and disposed inside the base 1. The punching path of the punching head 2 is directly above the opening of the drawer 5, and the waste generated during the punching process falls directly into the drawer 5. The clamping mechanism 3 is used to securely fix the automotive parts to the base 1 before punching. The clamping mechanism 3 includes a clamping assembly 36 driven by a pneumatic cylinder 31. The clamping assembly 36 is provided with a clamping arm 361 for directly contacting and clamping the automotive parts. The fixing mechanism 4 is used to lock the drawer 5 inside the base 1 to prevent it from sliding out when the equipment is working. The fixing mechanism 4 includes an operating lever 41 for human operation and a fixing head 43 that is linked to the operating lever 41. The movement of the fixing head 43 is controlled by the operating lever 41. The fixing head 43 is used to selectively engage and lock or unlock and separate from the drawer 5.

[0025] Reference Figure 1 , Figure 2 and Figure 3 The clamping mechanism 3 includes a fixed plate 32 fixed on the base 1. The driving end of the pneumatic cylinder 31 passes through the fixed plate 32 and is connected to the connecting pin 33. The two ends of the connecting pin 33 are respectively rotatably connected to the rotating ring 34. The first end of the linkage rod 35 is rotatably connected to the rotating ring 34, and the second end of the linkage rod 35 is rotatably connected to the clamping assembly 36. When the pneumatic cylinder 31 extends or retracts, its driving end drives the linkage rod 35 to swing around the connection point between it and the rotating ring 34 through the connecting pin 33 and the rotating ring 34, thereby converting the linear reciprocating motion of the pneumatic cylinder 31 into the swing motion of the linkage rod 35. The clamping mechanism 3 drives the clamping arm 361 to achieve the action of closing clamping or opening release by retracting or extending the pneumatic cylinder 31.

[0026] like Figure 3 As shown, the clamping assembly 36 itself includes a fixed base 363 fixed on the base 1 and a rotating shaft 362 rotatably mounted on the fixed base 363. The clamping arm 361 is fixedly connected to the rotating shaft 362. The second end of the linkage rod 35 is rotatably connected to the clamping arm 361. In this way, the swinging motion of the linkage rod 35 can directly drive the clamping arm 361 to rotate around the axis of the rotating shaft 362, thereby realizing the clamping action. In this embodiment, two sets of clamping mechanisms 3 are symmetrically arranged on the base 1, so that the clamping arms 361 can clamp the car parts from both sides in a coordinated manner, resulting in more uniform force and more stable positioning.

[0027] The implementation principle of this application embodiment is as follows: The automotive parts punching protection mechanism is installed on the base 1 with a clamping mechanism 3. The clamping mechanism 3 fixes the automotive parts on the base 1 and punches them through the punching head 2 at the top. The clamping mechanism 3 is driven by a pneumatic cylinder 31. The driving end passes through the inside of the fixed plate 32 to push the connecting pin 33. Both ends of the connecting pin 33 are connected to rotating rings 34, so that the rotating rings 34 are pressed and rotated, driving the linkage rod 35 to rotate outward and pushing the clamping assembly 36. Then, the clamping assembly 36 connected to the other end of the linkage rod 35 rotates around the fixed seat 363 through the rotating shaft 362, so that the clamping arm 361 unfolds outward, the angle is adjusted, and the pneumatic cylinder 31 retracts again to close the clamping arm 361 to clamp the object and fix it firmly on the base 1.

[0028] During the stamping process, the waste material is punched into the internal drawer 5 through the top hole. To prevent the drawer 5 from accidentally sliding out, a fixing mechanism 4 is installed on the outside. When the equipment is working, the fixing mechanism 4 fixes the drawer 5 inside the base 1. By pulling the operating lever 41 downward, the operating lever 41 rotates to the outside of the support base 42. The operating lever 41 drives the fixing head 43 to retract outward, and the limiting ring 45 inside the outer shell 46 compresses the spring 44, causing one end of the fixing head 43 to release the drawer 5, thus unlocking the drawer 5. Pulling the operating lever 41 upward again fixes the drawer 5.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
