Description

Technical Field

[0001] This invention relates to the field of milling equipment technology, specifically to an automated milling processing device for manufacturing automotive parts. Background Technology

[0002] High-pressure water jet milling equipment is used in the manufacturing of automotive parts to perform milling-based workpiece processing. This equipment uses ultra-high-pressure water jets to impact automotive parts, shaping their surface grooves or performing milling operations such as cutting. During this process, water splashes, causing waste liquid and milling debris to fly out over a wide area, polluting the environment and making subsequent cleaning difficult, thus reducing the cleanliness of the equipment. Some milling units have mechanisms outside the milling area for collecting splashed water, increasing the equipment's size, space requirements, and cost. Summary of the Invention

[0003] The purpose of this invention is to provide an automated milling processing device for automotive parts manufacturing, in order to solve the problems of inconvenient cleaning, large size and space occupation of existing milling devices.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automated milling processing device for manufacturing automotive parts, comprising:

[0005] The lifting platform is connected to the lifting drive equipment and is equipped with high-pressure water jet milling equipment and milling fluid spraying equipment.

[0006] The positioning mechanism includes a movable seat and a fixed seat arranged opposite each other. Each movable seat and fixed seat includes a base and a cover. An opening and closing drive device is connected to the movable seat to drive the movable seat to move relative to the fixed seat. The base is provided with a positioning groove for positioning automotive parts. The cover is located on the base. After the covers of the movable seat and the fixed seat are sealed and assembled, an isolation cavity is formed by surrounding the outside of the positioning groove. The cover is provided with a first pair of interfaces and a second pair of interfaces that are respectively connected to the high-pressure water jet milling equipment and the milling fluid injection equipment. The cover is provided with a suction port. The outer end of the suction port is connected to an external negative pressure generating device through a connector.

[0012] A waterproof sleeve is provided on the inner side of the first pair of interfaces, and the ends of the waterproof sleeves on the covers of the movable seat and the fixed seat are joined together and fitted onto the high-pressure water jet milling equipment.

[0013] As a further description of the above technical solution:

[0014] The second pair of interfaces is provided with a waterproof connecting sleeve, which is an elastic structure, and the nozzle of the milling fluid spraying device is inserted into the socket of the waterproof connecting sleeve.

[0015] As a further description of the above technical solution:

This satisfies the simultaneous milling fluid spraying and milling of automotive parts, while simultaneously blocking and uniformly extracting the waste generated during milling from the positioning mechanism for collection and processing. This avoids waste splashing everywhere, which would increase the difficulty of subsequent cleaning and affect the cleanliness of the device. Furthermore, it integrates the automotive part positioning mechanism with the waste recycling mechanism, reducing the size and space occupied by the device.

[0035] Example 1:

[0036] Please see Figure 1-4 This invention provides a technical solution: an automated milling processing device for automotive parts manufacturing, comprising:

[0037] The lifting platform 1 is connected to the lifting drive device 2, and a high-pressure water jet milling device 3 and a milling fluid spraying device 4 are installed on it;

[0038] The positioning mechanism includes a movable seat 5 and a fixed seat 6 arranged opposite to each other. Both the movable seat 5 and the fixed seat 6 include a base 7 and a cover 8. An opening and closing drive device 9 is connected to the movable seat 5 to drive the movable seat 5 to move relative to the fixed seat 6. The base 7 is provided with a positioning groove 10 for positioning automotive parts. The cover 8 is located on the base 7. After the cover 8 of the movable seat 5 and the fixed seat 6 are sealed and assembled, an isolation cavity is formed by surrounding the outside of the positioning groove 10. The cover 8 is provided with a first pair of interfaces 11 and a second pair of interfaces 12 that are respectively connected to the high-pressure water jet milling device 3 and the milling fluid injection device 4. The cover 8 is provided with a suction port 13. The outer end of the suction port 13 is connected to an external negative pressure generating device through a connector 14.

[0039] Among them, the lifting drive device 2 and the opening and closing drive device 9 can adopt linear drive devices and mechanisms such as linear motors to realize the stable lifting control of the high-pressure water jet milling device 3 and the milling fluid spraying device 4, as well as the switching of the opening and closing state of the positioning mechanism.

[0040] The positioning groove 10 can adopt a stepped structure with a larger lower cross-sectional dimension and a smaller upper dimension, so that the automotive parts can be laterally inserted into the positioning groove 10 of the fixed seat 6 for initial assembly, and laterally inserted into the positioning groove 10 of the movable seat 5 after the positioning mechanism is closed to complete the horizontal limiting. The positioning groove 10 can restrict the automotive parts in the vertical direction and improve the positioning stability of the workpiece.

[0041] The jet structure housing of the high-pressure water jet milling equipment 3 is connected to the first pair of interfaces 11. The nozzle is installed inside the jet structure housing by linear drive devices such as cylinders, hydraulic cylinders, and electric cylinders. The aforementioned linear drive devices can enable the nozzle to move along at least one of the X-axis, Y-axis, and Z-axis to meet the milling requirements of automotive parts.

[0042] The suction port 13 uses the negative pressure environment created by the negative pressure generator to draw out the waste liquid and solid waste generated during the milling process. An air inlet is provided on the surface of the cover 8 or at the first pair of interfaces 11 and the second pair of interfaces 12, so that the gas is replenished into the isolation chamber.

[0043] The isolation chamber is spherical, which causes the water jets from the high-pressure water jet milling equipment 3 and the milling fluid jetting equipment 4 to impact the automotive parts and form splash water jets that are blocked by the top of the spherical surface of the cover 8 and guided from the bottom of the spherical surface to the suction port 13, thereby improving the efficiency of milling waste blocking and collection.

[0044] Waterproof pads 15 are provided on the joint sides of the movable seat 5 and the fixed seat 6 to improve the waterproof performance of the joints of the positioning mechanism.

[0045] A waterproof sleeve 16 is provided on the inner side of the first pair of interfaces 11. The ends of the waterproof sleeve 16 on the cover 8 of the movable seat 5 and the fixed seat 6 are spliced ​​and sleeved on the high-pressure water jet milling equipment 3 to improve the waterproof performance of the connection between the cover 8 and the high-pressure water jet milling equipment 3.

[0046] A waterproof connecting sleeve 17 is provided inside the second pair of interfaces 12. The waterproof connecting sleeve 17 is an elastic structure. The nozzle of the milling fluid spraying device 4 is inserted into the socket 18 of the waterproof connecting sleeve 17 to prevent milling waste from flying out of the positioning mechanism through the second pair of interfaces 12 and the milling fluid spraying device 4 and causing pollution to the external environment.

[0047] The working principle of an automated milling device for automotive parts manufacturing in this embodiment includes: This milling device, through a positioning mechanism design with a cover 8, can sequentially complete the process of positioning automotive parts, moving the high-pressure water jet milling equipment 3 and the milling fluid injection equipment 4 into position, and isolating the milling area from the external environment during milling. Specifically, the automotive parts are first placed on the positioning groove 10 of the fixed seat 6. The opening and closing drive device 9 drives the moving seat 5 towards the fixed seat 6, causing the positioning mechanism to close. The automotive parts align with the positioning groove 10 of the moving seat 5, completing workpiece positioning and forming initial isolation. Then, the lifting drive device 2 drives the high-pressure water jet milling equipment 3 and the milling fluid injection equipment 4 to move downwards, respectively aligning with their corresponding interfaces to complete the isolation inside and outside the positioning mechanism. Afterwards, the equipment operates, performing milling fluid injection and milling operations. Simultaneously, a negative pressure generating device creates airflow at the suction port 13, which extracts the waste material generated during milling. Specifically, as shown... Figure 1-3 As shown. This satisfies the simultaneous spraying of milling fluid and milling of automotive parts, while blocking and uniformly extracting the waste generated during milling through a positioning mechanism for collection and processing. This avoids waste splashing everywhere, which would increase the difficulty of subsequent cleaning and affect the cleanliness of the equipment. It also integrates the automotive parts positioning mechanism with the waste recycling mechanism, reducing the size and space occupied by the equipment.

[0048] Example 2:

[0049] Please see Figure 2 , 3 The figure shows an automated milling processing device for automotive parts manufacturing provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solution: Considering that the milling fluid injection device 4 is actually installed at an angle to meet the requirements of synchronous milling fluid spraying and milling, due to the above-mentioned device lifting drive method, there is structural interference when the milling fluid injection device 4 docks with the second pair of interfaces 12. Therefore, the following structural docking design is implemented: the side of the waterproof docking sleeve 17 is elastically and rotatably docked with the second pair of interfaces 12 via an elastic torsion block 19. The contact surfaces of the second pair of interfaces 12 and the waterproof docking sleeve 17 are mutually matching spherical surfaces. When the milling fluid injection device 4 is connected to the second pair of interfaces 12, the nozzle is initially inserted into the outer end of the socket 18. As the structure continues to move, the nozzle pushes the inner wall of the socket 18, causing the waterproof connecting sleeve 17 to rotate along the second pair of interfaces 12 to achieve adaptive adjustment of the structure. During this period, the nozzle continues to penetrate deeper into the socket 18 until it is fully connected. As the waterproof connecting sleeve 17 rotates, the elastic torsion block 19 undergoes elastic torsion and deformation simultaneously. When the milling fluid injection device 4 is disengaged from the second pair of interfaces 12, the waterproof connecting sleeve 17 automatically flips and resets with the help of the elastic force of the elastic torsion block 19.

[0050] Example 3:

[0051] Please see Figure 4 The figure shows an automated milling processing device for automotive parts manufacturing provided in Embodiment 3 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solution: The base 7 is provided with guide ribs 20 between the positioning groove 10 and the suction port 13. The guide ribs 20 are V-shaped structures with outward openings, located between adjacent suction ports 13. A passage gap 21 is formed between adjacent guide ribs 20, and the flow cross-section of the passage gap 21 gradually narrows from the inside to the outside. This allows for the guidance, diversion, and flow restriction of waste material moving towards the suction port 13, preventing it from rushing towards the suction port 13 in large quantities and causing blockage and failure of the waste material recycling function.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
