Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a deburring device for machining. Background Technology

[0002] In the field of machining, deburring the end face of a workpiece is a key process for improving product precision and surface quality.

[0003] Traditional deburring equipment often employs a fixed grinding structure, such as using a single rotating grinding wheel or brush head to grind the workpiece end face in one direction. This type of equipment typically relies on manual adjustment of the workpiece angle or multi-stage processing and is suitable for workpieces with simple geometries. In recent years, some improved equipment has introduced rotatable grinding heads or multi-axis robotic arms, controlling the grinding path through preset programs. However, these solutions often require a precision CNC system, resulting in higher costs and more complex operation. Furthermore, existing clamping mechanisms often use rigid fixtures to completely fix the workpiece. While this ensures processing stability, it restricts the workpiece's horizontal movement freedom during processing, leading to frequent workpiece disassembly or tooling adjustments after processing, making continuous production difficult.

[0004] The existing technology has the following significant drawbacks: traditional grinding heads can only rotate around their own axis and cannot achieve multi-angle composite motion, making it difficult to completely remove burrs on complex contours or inner hole edges; rigid clamping mechanisms completely lock the workpiece position, making it impossible to move the workpiece horizontally during processing, requiring repeated clamping or reliance on external conveying equipment, resulting in low efficiency; multi-degree-of-freedom grinding mechanisms lack linkage design with workpiece feed motion, relying on complex control programs, resulting in poor equipment stability and high maintenance costs; for irregularly shaped workpieces or long shaft parts, existing equipment cannot simultaneously handle simultaneous processing at both ends and continuous feeding, restricting its application in mass production scenarios.

[0005] In view of this, there is an urgent need for a method that can cover the entire angle of the workpiece end face through compound motion, while allowing the workpiece to move horizontally in the clamping state to adapt to continuous processing; and adopts a dynamic collaborative control mechanism to simplify the structure, reduce costs, and improve the process adaptability to irregular workpieces.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a deburring device for machining, comprising:

[0008] The processing box has a T-shaped partition fixedly connected vertically to its inner side.

[0009] The drive motor is installed in the first cavity;

[0010] A first bearing housing is installed in the first chamber and the third chamber, and the motor shaft of the drive motor passes through the first bearing housing and extends into the third chamber;

[0011] A C-shaped frame is disposed in the third chamber. The C-shaped frame is fixedly connected to the motor shaft of the drive motor. A deburring motor is installed at one end of the C-shaped frame, and a second bearing seat is installed at the other end of the C-shaped frame. A deburring component is provided on the inner side of the C-shaped frame. One end of the deburring component is fixedly connected to the motor shaft of the deburring motor, and the other end of the deburring component is fixed in the inner ring of the bearing in the second bearing seat.

[0012] The feed inlet is located on the side of the processing box near the third chamber. A support platform and an upper frame are fixedly connected to the outside of the feed inlet. A material-carrying base plate is fixedly connected to the support platform by bolts. Several sets of pressing mechanisms are provided on the upper frame.

[0013] Preferably, the front and rear sides of the first chamber and the third chamber are connected to movable door panels by hinges, and handles are fixedly connected to the movable door panels. The front and rear sides of the second chamber are provided with several sets of strip holes that penetrate the movable door panels.

[0014] Preferably, the deburring component corresponds to the position of the feed inlet, and the deburring component includes:

[0015] Central axis;

[0016] A fixing sleeve is fixed to the outside of the central shaft;

[0017] Several sets of polishing discs are fixedly connected to the outer surface of the fixed sleeve in a regular circular array.

[0018] Preferably, the pressing mechanism includes:

[0019] A threaded hole is formed through the upper frame;

[0021] A handle is fixedly connected to the top of the adjusting rod;

[0022] A slot is formed inside the bottom of the adjusting rod;

[0023] The pressure ball is movably connected within the rotating groove.

[0024] Preferably, the inner diameter of the opening of the rotating groove is smaller than the diameter of the pressure bead.

[0025] Preferably, the third chamber is provided with a waste collection mechanism, the waste collection mechanism comprising:

[0026] A slot is formed through the lower end of the T-shaped partition;

[0027] A bayonet is provided at the lower end of the processing box body on the side near the feed inlet;

[0028] The collection box is connected to the third chamber through the bayonet;

[0029] An insert block is fixedly connected to the collection box, and the insert block is inserted into the slot.

[0030] Preferably, the collection box is located below the deburred part, and the collection box is suitable for collecting waste material after the workpiece deburring process.

[0031] Compared with the prior art, the beneficial effects of this utility model are:

[0032] 1) This application combines the self-rotation cutting of the deburred part with the revolution scanning of the C-frame through the coordinated control of the drive motor and the deburring motor, forming a multi-angle grinding trajectory around the end face of the workpiece. This design allows the grinding disc to cover all circumferential areas of the end face of the workpiece, and is especially suitable for complex structures with holes, grooves or curved surfaces. It can completely remove burrs in all directions without manual intervention, significantly improving processing quality and efficiency.

[0033] 2) The holding mechanism of this application adopts a vertical pressure and horizontal free guidance design. It can stabilize and fix the workpiece through multi-point pressure distribution to prevent displacement caused by processing vibration, and allow the workpiece to move freely along the horizontal axis. This allows it to be directly connected to the production line to achieve continuous feeding, or the workpiece extension length can be manually adjusted during processing to adapt to one-time clamping and processing of workpieces of different sizes, greatly reducing auxiliary time.

[0034] 3) This application adopts a modular cavity layout to optimize functional zoning. The first chamber, as the control room, integrates the drive motor and control unit. The strip-shaped hole design enables natural heat dissipation, avoiding overheating of the motor and affecting operational stability, while also facilitating maintenance. The second chamber, as the storage area, can be used to temporarily store workpieces to be processed or already processed, allowing for quick access and shortening the process connection time. The third chamber, as the processing area, adopts a closed structure to isolate grinding dust. It integrates a waste collection mechanism inside, which collects debris in a directional manner through the collection box to prevent pollution from spreading and ensure a clean working environment. The three chambers work together to form an integrated layout of "control-storage-processing", which not only improves space utilization but also achieves physical isolation of the processing flow, ensuring operational safety and convenient maintenance.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0057] Please see Figure 1-9 This utility model provides a technical solution: a deburring device for machining, comprising:

[0058] The processing box 1 has a T-shaped partition 2 vertically fixedly connected to the inside of the processing box 1. The left side of the processing box 1 is divided into a first chamber 3 and a second chamber 4 by the T-shaped partition 2. The right side of the processing box 1 is divided into a third chamber 5 by the T-shaped partition 2. The bottom of the processing box 1 is equipped with a self-locking universal wheel 12.

[0059] The drive motor 6 is installed inside the first chamber 3;

[0060] The first bearing housing 7 is installed in the first chamber 3 and the third chamber 5, and the motor shaft of the drive motor 6 passes through the first bearing housing 7 and extends into the third chamber 5;

[0061] C-shaped frame 8 is installed in the third chamber 5. C-shaped frame 8 is fixedly connected to the motor shaft of drive motor 6. Deburring motor 9 is installed at one end of C-shaped frame 8, and second bearing seat 11 is installed at the other end of C-shaped frame 8. Deburring part 10 is provided on the inner side of C-shaped frame 8. One end of deburring part 10 is fixedly connected to the motor shaft of deburring motor 9, and the other end of deburring part 10 is fixed in the bearing inner ring of second bearing seat 11.

[0062] The feed inlet 13 is located on the side of the processing box 1 near the third chamber 5. A support platform 14 and an upper frame 15 are fixedly connected to the outside of the feed inlet 13. A material-carrying base plate 19 is fixedly connected to the support platform 14 by bolts. Several sets of pressing mechanisms 20 are provided on the upper frame 15.

[0063] Specifically, the C-shaped frame 8 is driven by the drive motor 6 to revolve, while the deburring motor 9 drives the deburring part 10 to rotate at high speed. The combined motion of the two creates a three-dimensional processing path for the grinding disc 1003, characterized by "spiral cutting + circumferential coverage," making it particularly suitable for all-around deburring of gear end faces, deep hole inner walls, or irregularly shaped curved workpieces. The support platform 14 on the outside of the feed port 13 is bolted to a replaceable loading base plate 19, adapting to the load-bearing requirements of workpieces of different sizes. The pressing mechanism 20 of the upper frame 15, through a coordinated design of vertical pressure and horizontal guidance, allows the workpiece to freely feed or retract along the horizontal axis during processing, achieving seamless integration with automated production lines. The self-locking casters 12 at the bottom of the processing box 1 allow for flexible movement on the workshop floor and, through a locking function, ensure the stability of the equipment during processing, preventing accuracy deviations caused by vibration. The overall design, through the combination of modular cavities and composite motion control, effectively improves processing efficiency while reducing energy consumption and maintenance costs.

[0064] Reference manual attached Figure 1-2The first chamber 3 and the third chamber 5 are hinged to movable door panels 16 on both the front and rear sides. Handles 17 are fixedly connected to the movable door panels 16. Several sets of slotted holes 18 are formed through the movable door panels 16 on both the front and rear sides of the second chamber 4. Specifically, the handles 17 facilitate the operation of the movable door panels 16, allowing for quick opening and closing of the movable door panels 16 on both the front and rear sides of the first chamber 3 and the third chamber 5. This facilitates rapid maintenance of the drive motor 6 or replacement of the deburring parts 10, significantly reducing equipment downtime. The second chamber 4 can serve as a multi-functional storage area, storing workpieces to be processed, spare grinding discs 1003, or tools. This allows operators to complete material preparation, processing, and cleaning at the same workstation, reducing material handling distances within the workshop and improving overall production efficiency. The slotted holes 18 allow for heat dissipation within the first chamber 3 and the second chamber 4. When the drive motor 6 is running, heat can be expelled through the slotted holes 18.

[0065] Reference manual attached Figure 3 and instruction manual attached Figure 6-7 The deburring part 10 is positioned corresponding to the feed inlet 13, and the deburring part 10 includes:

[0066] Central axis 1001;

[0067] The fixing sleeve 1002 is fixed to the outside of the central shaft 1001;

[0068] Several sets of polishing discs 1003 are fixedly connected to the outer surface of the fixing sleeve 1002 in a regular ring array.

[0069] Specifically, depending on the actual usage requirements, different materials can be selected for the 1003 grinding disc. The 1003 grinding disc can be made of ceramic-bonded corundum for coarse grinding and deburring of medium-hardness metals such as cast iron and stainless steel. The high toughness of the ceramic bond allows it to withstand intermittent impact loads on heavy workpieces (such as engineering machinery castings), and after the abrasive grains break, new cutting edges are formed, maintaining continuous sharpness. Alternatively, the 1003 grinding disc can be made of nylon fiber bristles (containing silicon carbide abrasive grains) for flexible deburring and chamfering polishing of plastic, rubber, and 3D printed resin workpieces. The nylon bristles bend and deform to conform to curved surfaces, removing burrs from injection molded parts without residue.

[0070] Specifically, the deburring part 10 adopts a detachable design. The central shaft 1001 is connected to the fixed sleeve 1002 through an interference fit. When the deburring motor 9 drives the central shaft 1001 to rotate, the grinding disc 1003, in conjunction with the revolution of the C-shaped frame 8, combines the rotational cutting of the deburring part 10 with the revolution scanning of the C-shaped frame 8 to form a multi-angle grinding trajectory around the end face of the workpiece. This design allows the grinding disc 1003 to cover all circumferential areas of the end face of the workpiece, which is especially suitable for complex structures with holes, grooves or curved surfaces. It can completely remove burrs in all directions without manual intervention, significantly improving processing quality and efficiency.

[0071] Reference manual attached Figure 1 and instruction manual attached Figure 9 The pressure holding mechanism 20 includes:

[0072] Threaded hole 2001, through-hole is opened in the upper frame 15;

[0073] The adjusting rod 2002 is connected to the threaded hole 2001 via a threaded structure;

[0074] The handle 2003 is fixedly connected to the top of the adjusting rod 2002;

[0075] The rotating groove 2004 is located inside the bottom of the adjusting rod 2002;

[0076] The pressure ball 2005 is movably connected within the rotating groove 2004.

[0077] Specifically, the control handle 2003 allows for vertical displacement adjustment of the adjusting rod 2002, thereby precisely controlling the downward pressure of the pressure balls 2005 on the workpiece. Multiple pressure balls 2005 hold workpieces of different specifications and shapes. When the workpiece is fed horizontally, the pressure balls 2005 form rolling friction with the workpiece surface, preventing scratches on the workpiece surface and ensuring smooth feeding. For standard workpieces, multiple holding mechanisms 20 synchronously adjust the positions of the adjusting rod 2002 and the pressure balls 2005 to avoid machining deviations caused by eccentric clamping. For irregularly shaped workpieces, the multi-point independent adjustment holding design can adapt to contour changes, ensuring uniform pressure distribution.

[0078] Specifically, the holding mechanism 20 of this application adopts a design of vertical pressure application and horizontal free guidance. It can stabilize and fix the workpiece through multi-point pressure distribution to prevent displacement caused by processing vibration, and allow the workpiece to move freely along the horizontal axis. This allows it to be directly connected to the production line to achieve continuous feeding, or the workpiece extension length can be manually adjusted during processing to adapt to one-time clamping and processing of workpieces of different sizes, greatly reducing auxiliary time.

[0079] Reference manual attached Figure 9 The inner diameter of the opening of the rotating groove 2004 is smaller than the diameter of the pressure ball 2005. Specifically, this ensures that the pressure ball 2005 rolls freely while the rotating groove 2004 limits its movement, preventing it from detaching from the groove. Furthermore, the rolling contact mode of the pressure ball 2005 can dynamically compensate for workpiece thickness tolerances (±0.5mm). For example, when the workpiece has slight warping, the pressure ball 2005 can float with the shape, avoiding local overpressure or workpiece deformation caused by rigid clamping. This is particularly suitable for non-destructive machining of thin-walled shells or brittle workpieces after heat treatment.

[0080] Reference manual attached Figure 3 and instruction manual attached Figure 5The third chamber 5 is equipped with a waste collection mechanism 21, which includes:

[0081] Slot 2101 is through-cut into the lower end of T-shaped partition 2;

[0082] The bayonet 2102 is opened through the lower end of the side of the processing box 1 near the feed port 13;

[0083] The collection box 2103 is connected to the third chamber 5 through the bayonet 2102;

[0084] Insert 2104 is fixedly connected to collection box 2103 and inserted into slot 2101.

[0085] Specifically, the insert 2104 and the slot 2101 have a rectangular structure that matches each other. The height and length of one side of the collection box 2103 match the height and length of the bayonet 2102, respectively. A handle 17 is fixedly connected to the outside of the collection box 2103. After the collection box 2103 is inserted, it can be stably connected to the third chamber 5. When processing the workpiece, the waste material is automatically dropped into the collection box 2103 by gravity. The debris is collected in a directional manner by the collection box 2103 to prevent the spread of pollution and ensure a clean working environment.

[0086] The collection box 2103 is located below the deburred part 10 and is suitable for collecting waste material after the workpiece deburring process. Specifically, the collection box 2103 is made of transparent PC material and can be horizontally pulled out through the latch 2102 on the side of the processing box 1. The transparent PC material side wall of the collection box 2103 allows the operator to directly observe the waste material accumulation state.

[0087] Specifically, this application adopts a modular cavity layout to optimize functional zoning. The first chamber 3 serves as the control room, integrating the drive motor 6 and control unit. Natural heat dissipation is achieved through the design of the strip-shaped holes 18, avoiding overheating of the motor and affecting operational stability, while also facilitating maintenance and operation. The second chamber 4 serves as a storage area, which can be used to temporarily store workpieces to be processed or already processed, allowing for quick access and shortening the process connection time. The third chamber 5 serves as the processing area, adopting a closed structure to isolate grinding dust. An internal waste collection mechanism 21 is integrated, which uses a collection box 2103 to directionally collect debris, preventing pollution from spreading and ensuring a clean working environment. The three chambers work together to form an integrated layout of "control-storage-processing", which not only improves space utilization but also achieves physical isolation of the processing flow, ensuring operational safety and convenient maintenance.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
