Description

Technical Field

[0001] This utility model relates to the technical field of drilling processing equipment, specifically a tooling for processing automotive mechanical parts. Background Technology

[0002] Drilling is a crucial and frequently performed process in the manufacturing of automotive parts. With the rapid development of the automotive industry towards high performance, lightweight design, and intelligent manufacturing, unprecedented challenges have been placed on the precision, efficiency, and stability of drilling processes for automotive parts.

[0003] Traditionally, drilling tools for automotive parts have many drawbacks.

[0004] In the clamping process, many small auto repair shops or workshops often use simple mechanical clamps, such as single-sided screw clamps. Taking drilling holes in automotive chassis connecting parts as an example, this type of clamp can only apply pressure from one side, which cannot guarantee the all-round stability of the parts during the drilling process. When the drill bit rotates at high speed and cuts in, the parts are very prone to displacement due to uneven force, which can lead to problems such as drilling position deviation and substandard hole diameter accuracy. This greatly affects the assembly quality of the parts and may even pose a hidden danger to the safety of the entire vehicle.

[0005] Traditional tooling has limited positioning accuracy. When machining small holes used to install various sensors, such as those on a car engine block, the lack of high-precision positioning aids forces workers to rely on simple measuring tools like calipers and squares for manual measurement and positioning. This is not only cumbersome and time-consuming, but also susceptible to human error, making it difficult to ensure the accuracy of each drilled hole position, resulting in a significantly reduced yield.

[0006] Furthermore, with the increasing automation of automobile production, traditional drilling tooling exhibits extremely poor compatibility with automated production lines. It cannot quickly respond to commands from automated control systems, hindering efficient production modes such as automated loading and unloading and multi-station continuous drilling. This severely impedes automobile manufacturers' efforts to further increase production capacity, reduce costs, and enhance market competitiveness. Therefore, there is an urgent need for a new, high-precision, and high-efficiency tooling specifically designed for drilling automotive parts to overcome these challenges. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figure 1-4 As shown, an embodiment of the present invention provides a machining fixture for automotive mechanical parts, including a frame 1, wherein a mounting lug 2 is fixedly connected to the side of the frame 1.

[0028] The mounting lug 2 has several mounting holes. Its function is to use bolts or other fasteners to securely mount the fixture to the worktable through these holes, ensuring the stability of the fixture throughout the machining process and preventing machining accuracy from being affected by fixture movement.

[0029] A clamping hydraulic cylinder 3 is installed on the top of the frame 1, and a clamping plate 4 is fixedly connected to the output end of the clamping hydraulic cylinder 3;

[0030] When parts need to be processed, the clamping hydraulic cylinder 3 is activated, pushing the clamping plate 4 downward. Together with the frame 1, it applies clamping force to the parts from both the top and bottom directions, keeping the parts fixed during processing. This prevents problems such as drilling position deviation and non-compliance with hole diameter accuracy caused by part displacement, ensuring processing accuracy and quality.

[0031] A displacement hydraulic cylinder 5 is fixedly installed on the top of the frame 1. A flange 6 is fixedly connected to the output end of the displacement hydraulic cylinder 5. A rotary motor 7 is installed by bolts through the flange 6. A bushing 8 is sleeved on the output end of the rotary motor 7. A drill rod 9 is sleeved on the bottom of the bushing 8.

[0032] The output end of the rotary motor 7 is sleeved with the bushing 8, and the bottom of the bushing 8 is sleeved with the drill rod 9. The rotation of the rotary motor 7 drives the drill rod 9 to rotate at high speed, realizing the drilling operation on the part; the displacement hydraulic cylinder 5 can adjust the position of the drill rod 9 according to the different drilling position requirements of the part, improving the applicability of the tooling.

[0033] A guide groove 10 is provided on the side wall of the frame 1. A guide rail 11 is fixedly installed on the side wall of the frame 1 on one side of the guide groove 10. A slider 12 is slidably connected in the guide rail 11. A positioning hole 13 is provided in the slider 12. A collection groove 14 is provided on one side of the clamping plate 4 on the frame 1. The collection groove 14 is connected to the waste trough 15 inside the frame 1. An electric push rod 16 is fixedly connected inside the waste trough 15. A push plate 17 is fixedly connected to the output end of the electric push rod 16.

[0034] During the drilling process, the generated waste material falls into the collection tank 14 and flows into the waste material tank 15. After the processing is completed, the electric push rod 16 is activated to push the push plate 17 to push the waste material out of the waste material tank 15, thereby realizing the automatic collection and cleaning of waste material, keeping the processing area clean, and avoiding the accumulation of waste material from affecting the processing operation and the quality of the parts.

[0035] When this automotive mechanical parts machining fixture is in operation, it is first fixed to the worktable via the mounting lugs 2 on the side of the frame 1. The part to be processed is placed on the frame 1, and the clamping hydraulic cylinder 3 is activated. Its output end pushes the clamping plate 4 downward, cooperating with the frame 1 to clamp and fix the part. Next, according to the drilling position requirements, the displacement hydraulic cylinder 5 is activated, pushing the flange 6 and the rotary motor 7 mounted on it to move along the guide groove 10 and the guide rail 11. The slider 12 slides in the guide rail 11 for auxiliary positioning. After positioning is completed, the rotary motor 7 is powered on and drives the bushing 8 and the drill rod 9 fitted at the bottom to rotate at high speed for drilling. The wire of the rotary motor 7 passes through the positioning hole 13 on the slider 12, and the reserved length ensures that the wire is not pulled when the motor moves. The waste generated during drilling falls into the collection tank 14 and flows into the waste tank 15. After processing is completed, the electric push rod 16 is activated, and its output end pushes the U-shaped push plate 17 to push the waste out of the waste tank 15, thus completing the entire processing and waste cleaning process.

[0036] like Figure 2As shown, in some embodiments, there are four hollow mounting ears 2, and each mounting ear 2 has several mounting connection holes. The four mounting ears 2 are distributed on the side of the frame 1 to form a stable support structure. The hollow structure of the mounting ears 2 effectively reduces the overall weight of the tooling while ensuring its fixing function. The several mounting connection holes on the mounting ears 2 provide multiple options for the installation of the tooling.

[0037] like Figure 1 As shown, in some embodiments, the clamping plate 4, in conjunction with the frame 1, clamps the object for machining. During part machining, especially high-precision operations such as drilling, the stability of the part is crucial. Driven by the clamping hydraulic cylinder 3, the clamping plate 4 applies pressure towards the frame 1, firmly fixing the part between them. This prevents the part from shifting due to the cutting force generated by the high-speed rotation of the drill bit.

[0038] like Figure 3 As shown, in some embodiments, the bushing 8 is installed and fastened to the output end of the rotary motor 7 and the drill rod 9 by bolts passing through them respectively, and the bolt installation positions are perpendicular to each other and do not interfere with each other; by fastening the bushing 8 by bolts passing through the output end of the rotary motor 7 and the drill rod 9 respectively, it can be ensured that the bushing 8 is tightly connected to both.

[0039] like Figure 2 As shown, in some embodiments, the positioning hole 13 is used to connect the wire of the rotary motor 7. The slider 12 and the rotary motor 7 are fitted with a plastic tube on the wire, and a certain length of the wire is reserved on one side of the positioning hole 13. When drilling different positions of automotive parts, the motor can freely adjust its position to ensure that the drill rod 9 accurately reaches the processing point, improve the flexibility and accuracy of processing, and avoid the processing effect being affected by the motor movement being restricted by the wire being too short.

[0040] like Figure 4 As shown, in some embodiments, the pusher plate 17 is U-shaped, with one end of the pusher plate 17 flush with one end of the collection trough 14. The U-shaped design of the pusher plate 17 can better conform to the shape and accumulation state of the waste material. Compared with a flat pusher plate 17, it can more effectively gather and push the waste material. In the process of processing automotive mechanical parts, the waste materials generated are of various shapes. The U-shaped pusher plate 17 can apply pushing force to the waste material from multiple directions, preventing the waste material from scattering during the pushing process, ensuring that as much waste material as possible is cleaned out of the collection trough 14 and the waste material trough 15, thereby improving the waste material cleaning efficiency.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
