Description

Technical Field

[0001] This utility model belongs to the field of processing equipment technology and relates to a device for trimming burrs on castings. Background Technology

[0002] Castings, as an important basic manufacturing process product, are widely used in many industrial fields and have extremely diverse application scenarios. When castings are first made, the excess metal on the surface or edges of the castings due to the casting process, also known as "burrs," not only affect the appearance quality of the parts but may also have adverse effects on subsequent processing, assembly, and performance. As the manufacturing industry continues to increase its requirements for product precision and quality, effective deburring technology has become particularly important.

[0003] For example, a utility model patent with application number CN214135289U provides a deburring device for castings. This solution "includes a workbench, a support frame fixedly welded to the upper end of the workbench, a support plate fixedly welded to the upper end of the support frame, a groove provided inside the support plate, a bolt slidably sleeved inside the groove, a nut connected to the lower end of the bolt by a thread, a connecting block slidably sleeved on the outer side of the bolt, a baffle fixedly welded to one end of the connecting block, and a motor fixedly installed at the upper end of the workbench. This deburring device for castings can adjust the tilt angle of the baffle by rotating and loosening the bolt and nut, and rotating the baffle to drive the connecting block to rotate. The design of the baffle and support plate can provide a support platform for the casting and prevent shaking when manually holding the casting to grind burrs."

[0004] In summary, although some existing technical solutions have solved the problem of fixing castings during deburring, traditional devices cannot adjust the clamping according to castings of different sizes, leaving considerable room for improvement. Summary of the Invention

[0005] The purpose of this utility model is to address the aforementioned problems existing in the prior art by proposing a casting burr trimming device, comprising:

[0006] The base includes a base and an upper shell, the upper shell being connected to the base, and the upper shell having a processing space;

[0007] A clamping assembly is housed in the processing space. The clamping assembly includes a sliding block, a clamping block, and a telescopic connector. The sliding block is slidably connected to the upper shell. One end of the telescopic connector is connected to the sliding block, and the other end of the telescopic connector is connected to the clamping block. The clamping block can be driven to move away from or closer to the sliding block.

[0008] In the above-mentioned casting burr trimming device, the clamping assembly further includes a positioning plate, one end of which is rotatably connected to the sliding block. The positioning plate is provided with a first magnet, and the upper shell is provided with a second magnet. The first magnet can be attracted to the second magnet during the rotation of the positioning plate.

[0009] In the above-mentioned casting burr trimming device, the clamping block is provided with a first threaded portion, and the telescopic connector is provided with a second threaded portion, wherein the first threaded portion and the second threaded portion engage.

[0010] In the above-mentioned casting burr trimming device, the upper shell is further provided with a sliding groove, and the sliding block is partially accommodated in the sliding groove, so that the sliding block is slidably connected to the upper shell.

[0011] In the above-mentioned casting burr trimming device, the clamping block is further provided with a clamping contact surface on the side away from the sliding block, and the clamping contact surface is provided with an included angle.

[0012] In the above-mentioned casting burr trimming device, the number of clamping components is at least two.

[0013] In the above-mentioned casting burr trimming device, the upper shell is provided with a rotating column, the base is provided with a rotating groove, and the upper shell is rotatably connected to the base by being accommodated in the rotating groove through the rotating column.

[0014] In the above-mentioned casting burr trimming device, the upper shell is further provided with a material feeding channel, which is located at the bottom of the processing space.

[0015] In the above-mentioned casting burr trimming device, the upper shell is also provided with a feeding cylinder, the feeding channel is inclined, and the end of the feeding channel is connected to the feeding cylinder.

[0016] The aforementioned casting burr trimming device further includes a friction-enhancing ring, and the rotating column is rotatably connected to the rotating groove via the friction-enhancing ring.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The clamping block can firmly clamp the casting located in the machining space from the side. This feature makes it adaptable to the fixing needs of castings of various sizes. Whether it is a small precision part or a large complex structure, it can be firmly positioned in the required position. The sliding block drives the casting to rotate, which makes it easier for the operator to access every corner of the casting to ensure the removal of all burrs and sharp edges, thereby ensuring the quality of the final product.

[0032] The specific embodiments described herein are merely illustrative examples of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the patent of this utility model or exceeding the scope defined by the appended claims.

[0033] like Figures 1-4 As shown, a burr trimming device for castings includes: a base 1 and a clamping assembly 2.

[0034] The base 1 includes a base 11 and an upper shell 12, the upper shell 12 being connected to the base 11, and the upper shell 12 being provided with a processing space 121.

[0035] The clamping assembly 2 is housed in the processing space 121. The clamping assembly 2 includes a sliding block 21, a clamping block 22, and a telescopic connector 23. The sliding block 21 is slidably connected to the upper shell 12. One end of the telescopic connector 23 is connected to the sliding block 21, and the other end of the telescopic connector 23 is connected to the clamping block 22, which can drive the clamping block 22 away from or closer to the sliding block 21.

[0036] Specifically, the casting to be processed is placed in the processing space 121 of the upper shell 12. An electric push rod is provided in the telescopic connector 23, which can push the telescopic connector 23 to push the clamping block 22 to contact the casting in the processing space 121 and clamp and fix it. At the same time, the casting can also rotate in the processing space 121 as the sliding block 21 slides, so that deburring work can be performed at multiple angles.

[0037] In this embodiment, the clamping block 22 can firmly clamp the casting located in the processing space 121 from the side. This feature allows it to adapt to the fixing requirements of castings of various sizes. Whether it is a small precision part or a large complex structure, it can be firmly positioned in the required position. The sliding block 21 drives the casting to rotate, making it easier for the operator to access every corner of the casting, ensuring the removal of all burrs and sharp edges, thereby ensuring the quality of the final product. This design not only improves work efficiency, but also reduces the labor intensity of workers.

[0038] like Figures 1-4 As shown, based on the above embodiment, the clamping assembly 2 further includes a positioning plate 24. One end of the positioning plate 24 is rotatably connected to the sliding block 21. The positioning plate 24 is provided with a first magnet 241, and the upper shell 12 is provided with a second magnet 122. The first magnet 241 can be attracted to the second magnet 122 during the rotation of the positioning plate 24.

[0039] Specifically, the positioning plate 24 and the sliding block 21 are rotatably connected. When the positioning plate 24 is flipped away from the second magnet 122, the sliding block 21 can slide along the upper shell 12. When the positioning plate 24 is rotated to the point where the first magnet 241 and the second magnet 122 are attracted, the position of the sliding block 21 can be fixed.

[0040] In this embodiment, the design of the first magnet 241 on the positioning plate 24 and the second magnet 122 on the upper shell 12 enables the quick fixing and unlocking of the position of the clamping component 2, providing convenience during the deburring process of rotating the casting.

[0041] like Figures 1-4As shown, based on the above embodiment, the clamping block 22 is provided with a first threaded portion 221, and the telescopic connector 23 is provided with a second threaded portion 231, wherein the first threaded portion 221 engages with the second threaded portion 231.

[0042] In this embodiment, the connection between the telescopic connector 23 and the clamping block 22 is achieved by the engagement of the first threaded portion 221 and the second threaded portion 231. While ensuring its firmness and reliability, it also facilitates the disassembly of the clamping block 22. When the clamping block 22 is damaged or a different clamping block 22 is needed to clamp the casting, it can be replaced directly by rotating the clamping block 22.

[0043] like Figures 1-4 As shown, based on the above embodiment, the upper shell 12 is further provided with a sliding groove 123, and the sliding block 21 is partially accommodated in the sliding groove 123, so that the sliding block 21 is slidably connected to the upper shell 12.

[0044] In this embodiment, the sliding block 21 is partially housed within the provided sliding groove 123. In this way, a slidable connection is established between the sliding block 21 and the upper shell 12, ensuring that the sliding block 21 can move smoothly within it while maintaining sufficient stability.

[0045] like Figures 1-4 As shown, based on the above embodiment, the clamping block 22 is further provided with a clamping contact surface 222 on the side away from the sliding block 21, and the clamping contact surface 222 is provided with an included angle.

[0046] Specifically, when in contact with the surface of the casting, since the clamping contact surface 222 is provided with an included angle, the clamping contact surface 222 will have at least two points in contact with the casting to be processed.

[0047] In this embodiment, it is crucial to ensure stable and accurate positioning of the casting during the machining process. At least two different points or areas can simultaneously fit tightly against the surface of the casting. This means that no matter how complex the shape of the casting is, the clamping device can provide a more stable support point, thereby effectively avoiding the slippage or displacement of the casting during the machining process.

[0048] like Figures 1-4 As shown, based on the above implementation method, the number of clamping components 2 is at least two.

[0049] In this embodiment, there are at least two clamping components 2. The clamping components 2 can clamp the casting from multiple directions. Since the geometry of the casting is often complex, clamping in a single direction may not meet the need for fixation, especially when processing workpieces with grooves, protrusions or other irregular structures. By applying clamping force from multiple directions, it can not only better fit the surface of the casting, but also optimize and adjust the force characteristics of different areas. This flexibility allows the clamping device to adapt to various complex processing scenarios and provide reliable support for both planar and three-dimensional processing.

[0050] like Figures 1-4 As shown, based on the above embodiment, the upper shell 12 is provided with a rotating column 124, the base 11 is provided with a rotating groove 111, and the upper shell 12 is rotatably connected to the base 11 by being accommodated in the rotating groove 111 through the rotating column 124.

[0051] In this embodiment, the upper shell 12 is connected to the rotating groove 111 via the rotating column 124, thereby achieving a rotatable connection relative to the base 11. Without rotating the clamping assembly 2, the entire upper shell 12 can be rotated directly to make the casting rotate relative to the operator. The operator can complete the deburring of the casting at various angles without moving the position.

[0052] like Figures 1-4 As shown, based on the above embodiment, the upper shell 12 is also provided with a feeding channel 125, which is located at the bottom of the processing space 121.

[0053] In this embodiment, the feeding channel 125 located at the bottom of the processing space 121 can effectively utilize gravity to allow metal shavings of various sizes generated during the deburring process to fall naturally and collect there. This not only reduces the amount of manual cleaning work, but also avoids the safety hazards or impacts on other parts of the equipment that may be caused by shavings flying everywhere.

[0054] like Figures 1-4 As shown, based on the above embodiment, the upper shell 12 is also provided with a feeding cylinder 126, the feeding channel 125 is designed to be inclined, and the end of the feeding channel 125 is connected to the feeding cylinder 126.

[0055] In this embodiment, the debris accumulated in the feeding channel 125 can be discharged into the processing space 121 through the feeding cylinder 126. By rotating the upper shell 12 as a whole, the operator can easily access areas that are normally difficult to reach. During the rotation, the operator can use cleaning tools such as brushes to thoroughly clean all corners, including the clamping assembly 2, the sliding block 21, and other internal components.

[0056] like Figures 1-4 As shown, based on the above embodiment, a friction-enhancing ring 3 is also included, and the rotating column 124 is rotatably connected to the rotating groove 111 through the friction-enhancing ring 3.

[0057] In this embodiment, the rotating column 124 is rotatably connected to the rotating groove 111 via the friction-enhancing ring 3. The fixed column increases the rotational friction during the rotation with the friction-enhancing ring 3, thereby ensuring that the upper shell 12 has a certain resistance to rotation. Due to the existence of appropriate resistance, even in unstable environments, the upper shell 12 can maintain its set position, which greatly improves the stability and reliability of the entire device.
