Description

Technical Field

[0001] This utility model relates to a surface deburring device for aluminum die castings, and more particularly to a double-sided deburring device for aluminum die castings. Background Technology

[0002] After die casting, aluminum die-cast parts have burrs in multiple dimensions and on multiple sides, so multiple deburring processes are usually required.

[0003] CN117600977B patent discloses a metal surface deburring device, including a conveyor slide for carrying workpieces, a pushing module, and a grinding module. The grinding module includes two grinding components, each including a first motor, a sanding belt driven by the first motor, and an adjustment mechanism located inside the sanding belt. The sanding belt is wound in a ring and arranged opposite each other to form a grinding channel. The pushing module is used to push the workpiece through the grinding channel. The adjustment mechanism includes a fixed base, a pin on the fixed base, a rotating bearing, a push block assembly, and an eccentric wheel. One end of the pin is fixedly connected to the push block assembly, and the other end of the pin is rotatably connected to the rotating bearing. The eccentric wheel is driven by a wheel motor and is rotatably located on the side of the rotating bearing away from the pin. The rotation of the eccentric wheel allows the pin to move axially, pushing the push block to make the sanding belt adhere to the product surface to grind burrs. While conveying the workpiece, the device simultaneously grinds the two opposite sides of the workpiece, improving processing efficiency.

[0004] The aforementioned patent describes abrasive belts that are pressed tightly against the product surface to polish opposite sides of the workpiece, suitable for fine polishing of the workpiece surface, either locally or overall. However, the applicability of abrasive belt polishing is quite limited when dealing with workpieces that are already relatively flat but have only localized sharp burrs. This is because, on the one hand, abrasive belts are not ideal for removing these small and sharp burrs, making it difficult to achieve the desired polishing effect; on the other hand, these sharp burrs cause severe wear to the abrasive belt surface during polishing, greatly shortening the equipment's lifespan. Therefore, in such cases, the abrasive belt needs to be replaced frequently, which undoubtedly increases production costs and operational complexity. Utility Model Content

[0036] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0037] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Similarly, "first" and "second" are only for the purpose of facilitating understanding and have no other directional meaning, and should not be regarded as limitations on this utility model.

[0039] like Figure 1-4 As shown, this example provides a deburring device specifically designed for both sides of aluminum die castings. The device mainly consists of two core components: a positioning module 100 and a deburring module 200. The two work together to ensure that the burrs on both sides of the aluminum die castings are completely removed.

[0040] The positioning module 100 includes a positioning block 110 for supporting the aluminum die casting and a clamping assembly 120. The positioning block 110, with its stable structure, provides a solid support platform for the aluminum die casting; while the clamping assembly 120 firmly locks the aluminum die casting onto the positioning block 110 during operation, ensuring that it remains stationary during processing, which facilitates subsequent deburring work.

[0041] The deburring module 200 includes two sets of high-efficiency brushes 210, which are respectively positioned on the left and right sides of the positioning block 110. Each set of brushes 210 is equipped with a brush head 250 made of woven metal wire bundles. Each set of brushes 210 can be driven by a powerful motor to achieve synchronous and coordinated rotation, forming a working channel between them. Of course, in this embodiment, the deburring module 200 only includes one motor 220, which drives the two brushes 210 to rotate in opposite directions simultaneously through a transmission assembly, thereby improving synchronization and reducing costs.

[0042] Two sets of brushes 210 are mounted on a stable bracket 230. The bracket 230 rests on a mounting platform 270 equipped with a slide rail 240. The slide rail 240 extends linearly back and forth. In operation, the first cylinder 260 drives the bracket 230 to move smoothly back and forth along the slide rail 240, thereby controlling the brushes 210 to shuttle back and forth, allowing the brush head 250 to accurately contact both sides of the aluminum die-casting held on the positioning block 110, ensuring efficient and precise deburring. The movement and specific details of the motor 220 and the first cylinder 260 are controlled by a controller to achieve coordination. Furthermore, the rotational speed of the motor 220 and the speed of the first cylinder 260 will differ depending on the amount and material differences of the burrs on the aluminum die-casting, to ensure optimal cleaning results.

[0043] like Figure 2 As shown, the upper surface of the positioning block 110 in this example has a contour protrusion that perfectly matches the shape of the aluminum die-casting part to be processed. This design not only ensures the precise positioning of the aluminum die-casting part on the positioning block 110, but also greatly improves the stability and accuracy of subsequent processing.

[0044] The clamping assembly 120 mainly consists of a vertically movable pressure rod 141 and a second cylinder 130 that drives the pressure rod 141. The lower end of the pressure rod 141 is equipped with a contouring pressure head 142 that corresponds to the shape of the contouring protrusion, so that it can fit tightly against the surface of the aluminum die-casting part located on the contouring protrusion, thereby achieving a stable and uniform clamping effect.

[0045] More preferably, the profile indenter 142 is designed as a detachable structure, allowing for easy replacement with indenters of different materials to meet specific aluminum die-casting requirements, thus achieving wider applicability and greater flexibility. This innovative design opens up broader prospects for the application of the clamping assembly 120.

[0046] During operation, the second cylinder 130 acts as a power source, driving the pressure rod 141 to move downwards vertically. As the pressure rod 141 gradually descends, the contouring pressure head 142 presses firmly onto the aluminum die casting, securing it securely to the positioning block 110. This ensures the absolute stability of the aluminum die casting during processing, facilitating subsequent deburring work.

[0047] In this example, the positioning block 110 and the clamping assembly 120 work together to form a precise and efficient clamping system. This system not only achieves precise positioning and stable clamping of aluminum die castings, but also greatly improves the efficiency and accuracy of subsequent deburring operations, providing strong technical support for the production and processing of aluminum die castings.

[0048] like Figure 2As shown, in this example, the clamping assembly 120 is mounted on a structurally stable mounting bracket 150. The mounting bracket 150 consists of core components such as an upper fixing plate 161, a lower fixing plate 162, a damping plate 170, and guide posts 180, forming a precise and efficient clamping system.

[0049] The upper fixing plate 161 serves as the top support of the mounting bracket 150, firmly securing the second cylinder 130 and providing power to the clamping assembly 120. The lower fixing plate 162 serves as the bottom support, ensuring the stability of the entire system. The damping plate 170 is cleverly positioned above the lower fixing plate 162 and is precisely fixedly connected to the pressure rod 141, the lower end of which passes precisely through the lower fixing plate 162 to perform the clamping action.

[0050] As a key component connecting the upper and lower fixing plates, the guide post 180 enhances the overall stability of the mounting bracket 150 and provides precise guidance for the up-and-down movement of the damping plate 170. The damping plate 170 slides smoothly along the guide post 180, ensuring the accuracy and smoothness of the clamping action.

[0051] Furthermore, an elastic component 190 is provided between the damping plate 170 and the lower fixed plate 162, which effectively improves the stability and durability of the clamping assembly 120. The profile pressure head 142 is made of high-quality plastic, which not only has good wear resistance but also effectively reduces friction with the aluminum die-casting, extending the service life of the clamping assembly 120.

[0052] like Figure 2-4 As shown, the brush head 250 is cylindrical and contains radially radiating metal wire bundles. The material of the metal wires can be flexibly selected according to requirements. The brush head 250 adopts a detachable connection design, which facilitates the replacement of brush heads 250 with different materials. It is securely fixed to the brush component 210 by the bracket 230.

[0053] like Figure 1-4 As shown, the profile pressure head 142 is located below the pressure rod 141, and the positioning block 110 is detachably installed. Different aluminum die castings correspond to different sizes of positioning blocks 110. The size of the aluminum die casting determines the size of the positioning block 110, and also determines the pressure of the pressure head. The second cylinder 130 is controlled by a controller, and the pressure of the pressure head can be changed by the controller.

[0054] Preferably, the molding head 142 is made of high-quality plastic material. This design not only significantly improves the stability and reliability of use, but also gives the molding head excellent durability and corrosion resistance.

[0055] like Figure 1As shown, the bracket 230 includes a base A for fixing the motor 220, two opposing arms B connected to the front end of the base A, a downwardly extending support leg C, and a slider D disposed at the lower end of the support leg C and cooperating with the slide rail 240.

[0056] In operation, the first cylinder 260 precisely drives the bracket 230, and the slider D moves back and forth along the slide rail 240, so that the brush head 250 precisely contacts and adheres to both sides of the aluminum die-casting held on the positioning block 110, thereby achieving efficient deburring.

[0057] like Figure 2 As shown, at the initial position, the positioning module 100 is in the raised state, and the profiling head 142 maintains a safe distance from the surface of the aluminum die casting; the slider of the deburring module 200 is in the retracted position, and the motor 220 stops working and is in standby mode.

[0058] like Figure 3 As shown, upon entering position two, the second cylinder 130 of the positioning module 100 is activated, and the contouring pressure head 142 presses down and tightly adheres to the surface of the aluminum die-casting, achieving a firm fixation of the aluminum die-casting. At this time, the slider of the deburring module 200 remains in the retracted position, and the motor 220 remains in the stopped state, awaiting the next instruction.

[0059] like Figure 3 As shown, when the device enters position three, the first cylinder 260 of the deburring module 200 is activated, pushing the bracket 230 to move back and forth along the slide rail 240. Simultaneously, the motor 220 is activated, driving the two sets of brushes 210 to rotate. While rotating, the brush head 250 slides along both sides of the aluminum die-cast part, effectively removing burrs from the parting line. After completing the deburring operation, the brush head 250 and the bracket 230 return to the initial position one. At the same time, the second cylinder 130 of the positioning module 100 is activated, causing the pressure head to rise and releasing the processed aluminum die-cast part, preparing for the next round of processing.

[0060] The technical solution provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this invention. The description of the above embodiments is only for the purpose of helping to understand this invention and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to this invention without departing from the principle of this invention, and these improvements and modifications also fall within the protection scope of the claims of this invention.
