Description

Technical Field

[0001] This application relates to the field of machining, and in particular to a device for deburring the sides of accessories. Background Technology

[0002] In the field of machining, industries such as automobiles have experienced rapid growth in recent years. The continuous progress of the automotive industry has not only driven the upgrading of the entire manufacturing sector but also prompted more stringent requirements for the machining precision and efficiency of various components. This is especially true for components used in automotive sensors such as LiDAR, which have extremely complex structures. The quality of their machining directly affects not only the sensor's performance but also the overall safety of the vehicle. Precise machining ensures stable sensor operation, providing reliable support for advanced functions such as autonomous driving, thus powerfully propelling the automotive industry towards intelligence and high-end development. Simultaneously, with the continuous increase in automobile production, the demand for components is also growing. Against this backdrop, improving machining precision and efficiency is particularly important; it is not only key to meeting market demands but also an inevitable trend in industry development. The specific structure of this component is as follows: from bottom to top, it consists of three sections: the first section, the second section, and the third section. The second section can be divided into the main body and extensions. Both sides of the main body extend outwards to form extensions. Due to the considerable length of the second section, the extensions on both sides require deburring. Because the component is relatively small, and the extensions are located between the first and second sections, deburring is particularly difficult. Current methods for deburring involve fixing the component in a simple fixture and then relying on experienced workers to perform precision machining. This method can, to some extent, meet the processing needs of small businesses or those with low processing requirements.

[0003] However, the existing processing method that relies on manual experience for cutting and deburring has significant drawbacks. These drawbacks are mainly reflected in the limited speed of manual operation, making it difficult to improve processing efficiency, failing to meet the demands of large-scale precision processing, and the differences in experience and skill levels among different workers leading to inconsistent product quality. Utility Model Content

[0004] In order to improve the processing efficiency of deburring the accessory and improve the uniformity of product quality, this application provides a deburring device for the side of the accessory.

[0005] This application provides a device for deburring the side of accessories, including a positioning table, a positioning structure, and a deburring assembly. The deburring assembly includes a cutting head and a cutting head drive. The positioning table is provided with a positioning groove for placing the accessory, and the groove wall has a receiving groove for accommodating the extension of the accessory. The positioning structure abuts against the accessory, and the cutting head drive drives the cutting head downward until the cutting head extends into the receiving groove to cut off the extension of the accessory. By adopting the above technical solution, the positioning table with a positioning groove for placing the accessory can initially position the accessory and prevent it from moving randomly during processing. The receiving groove in the positioning groove wall can accommodate the extension of the accessory, providing operating space for the cutting head to cut off the extension. The positioning structure abuts against the accessory to further fix the accessory and prevent it from shaking or shifting when the cutting head cuts off the extension, ensuring the accuracy of the cutting. The cutter head drive unit drives the cutter head downwards, allowing it to extend into the receiving groove to cut off the extension of the part. This achieves automated deburring, avoiding the problems of limited speed and inconsistent product quality associated with manual operation, improving processing efficiency, ensuring product quality stability, and meeting the needs of large-scale precision processing. Preferably, the bottom of the receiving groove extends outwards from the bottom of the positioning platform to form an opening. By adopting the above technical solution, the bottom of the receiving groove extends outwards from the bottom of the positioning platform to form an opening. This allows the cut-off extension to fall directly from the opening when the cutter head extends into the receiving groove to cut off the part's extension, preventing the extension from accumulating in the receiving groove and affecting subsequent deburring operations. This improves the continuity and stability of processing, thereby increasing processing efficiency and ensuring the quality of deburring, resulting in more stable and reliable product quality. Preferably, the bottom of the cutter head is provided with opposite cutting tips for cutting off the part's extension, and a clearance groove is recessed between the two cutting tips to form a clearance fit with the part's body. By adopting the above technical solution, the cutting tips are arranged opposite each other at the bottom of the cutter head. When the cutter head driver moves the cutter head downwards to extend into the receiving groove, the cutting tips can directly act on the extension of the accessory, achieving precise removal of the extension. Simultaneously, a recessed avoidance groove is provided between the two cutting tips. This groove forms a avoidance fit with the accessory body, preventing interference between the cutter head and the accessory body during the removal of the extension, ensuring smooth removal, improving processing accuracy and efficiency, reducing the risk of damage to the accessory body due to misoperation, and thus improving product processing quality. Preferably, the tips of both cutting tips extend towards the other cutting tip. By adopting the above technical solution, since the tips of both cutting tips extend towards the other cutting tip, this arrangement allows the cutting tips to be more accurately aligned with the extension when the cutter head moves downwards to remove the accessory extension, reducing the risk of miscutting the accessory body during the cutting process.Preferably, the tops of the two cutting tips are provided with limiting rods, the tops of which are connected to the cutter head drive. When the cutting tips cut off the extension of the accessory, the bottoms of the limiting rods abut against the top of the positioning table. By adopting the above technical solution, since the tops of the limiting rods are connected to the cutter head drive, when the cutter head drive drives the cutter head to move downwards to cut off the extension of the accessory, the limiting rods will move downwards along with the cutter head. When the cutting tips cut off the extension of the accessory, the bottoms of the limiting rods abut against the top of the positioning table, which provides a limiting effect for the downward movement of the cutter head, avoiding excessive downward movement of the cutter head and damage to the accessory body, ensuring the quality of accessory processing, and improving the stability and reliability of deburring, thereby improving the overall processing efficiency. Preferably, the positioning groove is a T-shaped groove. By adopting the above technical solution, since the accessory is divided into three sections from bottom to top, the second section can be divided into the accessory body and an extension. Both sides of the accessory body extend outwards to form the extension. The positioning groove is set as a T-shaped groove, which can adapt to the shape of the accessory, allowing the accessory to be stably placed in the positioning groove. This avoids shaking or displacement during the deburring process, thereby improving processing accuracy and stability, ensuring product processing quality, and also improving processing efficiency to meet the needs of large-scale precision processing. Preferably, the T-shaped groove extends out of the side wall of the positioning table to form three slots. By adopting the above technical solution, the positioning groove adopts a T-shaped groove and extends outward from the side wall of the positioning platform to form three slots. Since the parts are divided into three sections from bottom to top, the second section can be divided into the main body of the parts and the extension. Both sides of the main body of the parts extend outward to form the extension. The shape of the T-shaped groove is adapted to the structure of the parts. The three slots facilitate the positioning structure to enter the positioning groove through the slots and perform multi-directional abutment positioning of the parts, so that the parts can be stably placed in the positioning groove, avoiding shaking or displacement during the deburring process. This effectively improves the accuracy and stability of the parts positioning, thereby ensuring the precision and quality of the deburring process, improving the processing efficiency, and overcoming the problems of inconsistent product quality and low processing efficiency in the existing deburring process that relies on manual experience. Preferably, the positioning structure includes a positioning rod and a positioning rod drive component. The positioning rod extends from the slot into the positioning groove and abuts against the parts. By adopting the above technical solution, the positioning structure includes a positioning rod and a positioning rod drive component. The positioning rod extends from the T-slot out of the slot formed by the side wall of the positioning table and enters the positioning slot to abut against the accessory. Since the accessory needs to maintain a stable position during the deburring process, if the positioning is unstable, the cutter head may cause the accessory to shift when cutting off the extension, affecting the machining accuracy and quality.By using a positioning rod drive component to drive the positioning rod to extend from the slot into the positioning groove and abut against the part, the part can be stably positioned in the positioning groove, preventing the part from moving during the cutting of the extension by the cutter head. This ensures the accuracy and quality of the machining, improves the product qualification rate, and is more conducive to meeting the needs of large-scale precision machining.

[0006] In summary, this application includes at least one of the following beneficial technical effects: 1. The positioning table is equipped with a positioning groove for placing parts. The groove wall of the positioning groove is provided with a receiving groove for accommodating the extension of the parts. The positioning structure abuts against the parts. The cutter head drive unit drives the cutter head to move downward until the cutter head extends into the receiving groove to cut off the extension of the parts. Through this combination of positioning and driving, automated deburring is achieved, avoiding the problem of limited speed of manual operation, thereby improving processing efficiency. 2. The three slots of the T-shaped positioning groove facilitate multi-directional positioning of the positioning rod, avoiding the problem of reduced machining accuracy due to displacement during the processing of the parts; 3. The bottom of the cutter head is provided with cutting tips for cutting off the extension of the part. A clearance groove is recessed between the two cutting tips to form a clearance fit with the main body of the part. When the cutter head moves downward to cut off the extension, the cutting tips can act precisely on the extension. The clearance groove can prevent the cutter head from contacting the main body of the part, thereby improving the machining accuracy. Attached Figure Description

Detailed Implementation

[0009] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0010] This application provides an embodiment of a device for deburring the sides of accessories, referring to... Figure 1 and Figure 2The machining process includes a positioning table 1, a positioning structure 2, and a deburring assembly 3. The positioning table 1 has a positioning groove 11 for placing the part 4. The positioning structure 2 abuts against the part 4. The deburring assembly 3 is positioned directly above the positioning table 1 and moves vertically. The deburring assembly 3 can move downwards to cut off the extensions 41 on both sides of the part 4. The positioning groove 11 accurately places the part 4, ensuring it is in the predetermined machining position. The positioning structure 2 abuts against and fixes the part 4, preventing it from moving during the cutting process and ensuring the stability and accuracy of the machining.

[0011] Specifically, in this embodiment, the positioning table 1 includes a positioning groove 11 and a receiving groove 12. The positioning groove 11 is used to place the accessory 4, and its structure is a recess. The shape can be designed according to the shape of the accessory 4. In this embodiment, it is a T-shaped groove. The T-shaped groove extends out of the side wall of the positioning table 1 to form three slots, which facilitates the positioning rod 21 of the positioning structure 2 to extend into the positioning groove 11 from the slots and abut against the accessory 4. The groove wall of the positioning groove 11 has a receiving groove 12 for accommodating the extension part 41 of the accessory. The bottom of the receiving groove 12 extends out of the bottom of the positioning table 1 to form an opening. The function of this opening is that when the cutting head 31 extends into the receiving groove 12 to cut off the extension part 41, the generated waste can be discharged from the positioning table 1 through the opening, avoiding the accumulation of waste and affecting subsequent processing. In particular, the groove wall of the positioning groove 11 is also provided with a through hole 13, which leads to the side wall of the positioning table 1.

[0012] Specifically, this embodiment has four positioning structures 2, each including a positioning rod 21 and a positioning rod drive component 22. Three positioning rods 21 extend from the slot into the positioning groove 11 and abut against the accessory 4, and one positioning rod 21 extends from the through hole 13 into the positioning groove 11 and abuts against the accessory 4. The positioning rods 21 are designed as square columnar rods, and their ends can be adapted to the shape of the surface of the accessory 4. The positioning rod drive component 22 can be a cylinder, which achieves extension and contraction through the compression and expansion of internal gas, thereby driving the positioning rod 21 to move; or it can be an electric push rod, which has the advantage of high control precision and can more accurately control the moving distance and force of the positioning rod 21. The positioning rods 21 and the positioning rod drive component 22 are connected by a connecting structure, such as a threaded connection. The threaded connection facilitates installation and disassembly, and makes it easy to replace and repair the positioning rods 21 or the positioning rod drive component 22.

[0013] Specifically, the deburring assembly 3 in this embodiment includes a cutter head 31, a limiting rod 32, and a cutter head drive member 33. The output end of the cutter head drive member 33 is connected to the limiting rod 32, and the other end of the limiting rod 32 is connected to the cutter head 31. The bottom of the cutter head 31 is provided with cutting tips 311 for cutting off the extension portion 41 of the accessory. A recessed groove 312 is provided between the two cutting tips 311 to form a clearance fit with the main body of the accessory 4. The cutter head drive member 33 drives the cutter head 31 to move downward until the cutter head 31 extends into the receiving groove 12 to cut off the extension portion 41 of the accessory 4, achieving the effect of accurately removing the burrs from the extension portion 41 of the accessory. When the cutter head 31 is cutting, the recessed groove 312 can prevent the cutter head 31 from contacting the main body of the accessory 4, thereby preventing damage to the main body of the accessory 4 when cutting the extension portion 41. In this design, the tips of both cutting tips 311 extend towards the other cutting tip 311. This design allows the cutting tip 311 to more accurately align with the burr area when cutting into the extension 41, resulting in more precise cutting. The cutter head 31 is made of high-speed steel, which has high hardness and wear resistance, maintaining the sharpness of the tool during multiple cuts. Other embodiments may use cemented carbide, which has better cutting performance and can improve cutting efficiency and quality. The cutter head drive component 33 is a motor-driven lead screw transmission mechanism. The motor drives the lead screw to rotate, and the rotation of the lead screw is converted into the up and down movement of the cutter head 31. Other embodiments may use a hydraulic drive mechanism, which has a large driving force and can quickly push the cutter head 31 downward to perform cutting.

[0014] Specifically, the diameter of the limiting rod 32 is larger than that of the cutting head 31. When the cutting tip 311 cuts off the extension 41 of the accessory, the bottom of the limiting rod 32 abuts against the top of the positioning table 1. The function of the limiting rod 32 is to prevent the cutting head 31 from moving excessively downward, thus avoiding damage to the accessory 4.

[0015] The implementation principle of this embodiment is as follows: The burr removal processing device for the side of the accessory in this embodiment achieves the function of automatically removing the burrs from the extension portion 41 of the accessory through the cooperation of the positioning table 1, the positioning structure 2, and the burr removal assembly 3. The positioning groove 11 and the receiving groove 12 of the positioning table 1 provide accurate placement and cutting space for the accessory 4, ensuring that the accessory 4 is in a suitable processing position; the positioning rod 21 of the positioning structure 2 abuts and fixes the accessory 4 under the drive of the positioning rod drive member 22, preventing it from moving during the cutting process and ensuring the stability of the processing; the cutter head drive member 33 of the burr removal assembly 3 drives the cutter head 31 to move downward, and the cutting tip 311 of the cutter head 31 extends into the receiving groove 12 to cut off the extension portion 41 of the accessory 4. The limiting rod 32 ensures the accuracy and safety of the cutting and prevents the cutter head 31 from moving downward excessively and damaging the accessory 4. Compared with the existing processing methods that rely on manual labor, this device improves processing efficiency, and due to the precise cooperation of each component, it ensures the consistency of product quality and can meet the needs of large-scale precision processing.

[0016] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
