Description

Technical Field

[0001] This utility model relates to the field of metal core processing technology, specifically a metal core edge chamfering and deburring fixture. Background Technology

[0002] In some precision manufacturing fields, metal cores are usually formed by processes such as stamping, cutting, and forging. Due to the characteristics of the processing technology, burrs and sharp edges are easily generated on the edges after forming. If these defects are not dealt with, they will cause abnormal gaps in the fit of parts in the subsequent assembly process, and may also scratch operators or damage related components. Therefore, edge chamfering and deburring are key processes in metal core processing.

[0003] Currently, deburring of metal cores mostly employs a fixed-station processing method, where the fixture and metal core are in a fixed relative position. If different edges of the metal core need to be treated, repeated disassembly and adjustment of the clamping state are required. This is not only cumbersome and prone to causing positioning deviations in the metal core, but also prolongs processing time. Furthermore, the burrs and debris generated during processing easily adhere to the edges of the metal core and the surface of the grinding components, requiring manual cleaning afterward, increasing the complexity of the process. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a metal core edge chamfering and deburring fixture to solve the technical problems that the current metal core chamfering and deburring mostly adopts a fixed station processing method. If different edge parts of the metal core need to be processed, the clamping state needs to be repeatedly disassembled and adjusted, which is cumbersome. At the same time, the burrs and debris generated during the processing are easy to adhere to the edge of the metal core and the surface of the grinding components, which requires manual cleaning afterward, increasing the complexity of the process.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a metal core edge chamfering and deburring fixture is designed, including a base and a processing cylinder. A screw is threaded through the side wall of the left opening of the processing cylinder. The screw is threadedly connected to the processing cylinder, and one end of the screw located inside the processing cylinder is rotatably connected to a mounting plate. The side of the mounting plate facing the center of the processing cylinder is provided with flexible bristles. Two limiting rods are fixedly connected to the side of the mounting plate facing the inner wall of the processing cylinder. The limiting rods pass through the processing cylinder and are slidably connected to the processing cylinder. A collection frame is threadedly connected to the right end of the processing cylinder. A fixing block is fixedly connected to the side of the collection frame facing the inner side of the processing cylinder. An electromagnet is embedded and fixedly connected to the surface of the fixing block.

[0006] In this solution, the laterally moving processing cylinder drives the internal processing components to move, chamfering and deburring different edges of the metal core without disassembling and adjusting the clamping state of the metal core, greatly simplifying the operation process and avoiding secondary positioning deviations; at the same time, by rotating the screw, the mounting plate is moved, so that the flexible bristles fit against the edge of the metal core and the grinding area, brushing away the attached burrs and debris in real time, eliminating the need for subsequent manual cleaning, improving processing efficiency and the cleanliness of the metal core surface.

[0007] Preferably, a positioning frame is fixedly connected to the surface of the base, a turntable is provided on the inner side of the positioning frame, the turntable is rotatably connected to the positioning frame, and an adjustment groove is provided on the base surface on one side of the positioning frame.

[0008] In practical applications, the turntable can drive the metal core to rotate, and together with the processing components, the chamfering of the circumference edge can be completed in one go. The adjustment groove provides a path for the movement of the processing cylinder, which can be adapted to the processing of different parts of the metal core. There is no need to repeatedly disassemble and clamp, thus improving processing efficiency.

[0009] Preferably, a first unidirectional lead screw is rotatably connected to the inner side of the adjusting groove, a first moving block passes through the surface of the first unidirectional lead screw, and the first moving block is rotatably connected to the first unidirectional lead screw. The protrusion at the bottom of the processing cylinder is inserted into the inner side of the first moving block and is detachably connected to the first moving block by bolts.

[0010] In practical applications, rotating the No. 1 one-way lead screw can precisely adjust the lateral position of the processing cylinder, adapting to the processing of metal cores of different lengths; the processing cylinder and the No. 1 moving block are detachable, making it easy to replace or maintain the processing cylinder separately, reducing equipment maintenance costs.

[0011] Preferably, the surface of the turntable is provided with a rectangular groove, and a bidirectional lead screw is rotatably connected to the inner side of the rectangular groove. Two support blocks pass through the surface of the bidirectional lead screw. The support blocks are threadedly connected to the bidirectional lead screw, and a crossbar is fixedly connected to the side of the support block facing the processing cylinder. Several equidistant clamping blocks are fixedly connected to the opposite sides of the upper and lower crossbars, and the upper and lower clamping blocks are alternately distributed.

[0012] In practical applications, rotating the bidirectional lead screw can make the clamping blocks clamp the metal core synchronously. The alternating clamping blocks increase the contact area, prevent the metal core from deforming, and are suitable for stable clamping of metal cores of different diameters, especially for processing thin-walled metal cores.

[0013] Preferably, a servo motor is fixedly connected to the base surface on the left side of the positioning frame, and the tail end of the transmission seat of the servo motor is connected to the side frame of the turntable side wall via a coupling.

[0014] In practical applications, servo motors can precisely adjust the turntable speed, adapting to the processing of metal cores of different hardness, such as stainless steel and aluminum alloy. For hard metal cores, the speed can be reduced to ensure chamfering quality, while for soft metal cores, the speed can be increased to improve efficiency. The coupling transmission reduces power loss and ensures stable operation.

[0015] Preferably, the top of the processing cylinder is provided with a top groove, and an inclined frame is rotatably connected between the front and rear inner walls of the top groove. An electric push rod is fixedly connected to the surface of the inclined frame.

A sand block is detachably connected to the bottom of the bottom block by bolts. A sliding rod is fixedly connected to the top surface of the bottom block on one side of the electric push rod. The top of the sliding rod passes through the inclined frame above, and the sliding rod is slidably connected to the inclined frame.

[0016] In practical applications, the rotating tilting frame can adjust the chamfering angle of the sanding disc, and the electric actuator controls the lifting and lowering of the sanding disc to adjust the chamfering depth, adapting to different chamfering requirements; the sanding blocks are detachable, making it easy to replace sanding blocks of different grits, taking into account both coarse chamfering and fine finishing needs.

[0017] Preferably, a top frame is provided at the top of the processing cylinder on the right side of the top groove, and a second one-way screw is rotatably connected to the inner side of the top frame. A second moving block passes through the surface of the second one-way screw, and the second moving block is threadedly connected to the second one-way screw. A stop rod is provided between the second moving block and the tilting frame, and the two ends of the stop rod are rotatably connected to the tilting frame and the second moving block respectively through their respective hinge seats.

[0018] In practical applications, rotating the No. 2 unidirectional lead screw can finely adjust the tilting frame angle through the stop bar, with high angle adjustment accuracy, adapting to special angle chamfering requirements; the lead screw's self-locking characteristic ensures that the angle does not deviate during processing, improving chamfering stability.

[0019] Preferably, the inner side of the collection frame is provided with a filter screen, the right side surface of the collection frame is fixedly connected to a ventilation frame, and the inner side of the ventilation frame is equipped with a fan.

[0020] In practical applications, the fan generates negative pressure to accelerate debris collection, and the filter intercepts fine dust, preventing dust from spreading and polluting the environment, thus meeting the processing needs of cleanrooms. The filter can be disassembled and cleaned separately, and can be reused to reduce consumable costs and ensure long-term dust removal performance.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model features a horizontally movable processing cylinder that drives the internal processing components to move, performing chamfering and deburring on different edges of the metal core without disassembling or adjusting the metal core clamping state, greatly simplifying the operation process and avoiding secondary positioning deviations. At the same time, by rotating the screw to push the mounting plate to move, the flexible bristles fit against the edge of the metal core and the grinding area, brushing away the attached burrs and debris in real time, eliminating the need for subsequent manual cleaning, and improving processing efficiency and the cleanliness of the metal core surface.

[0022] 2. This utility model, through its enclosed processing cylinder structure, can effectively prevent dust and debris generated during processing from drifting outward, thus avoiding pollution of the processing environment and affecting the health of operators. At the same time, the electromagnet in the collection frame at the right end of the processing cylinder can attract metal debris, which, together with the filter screen, intercepts fine dust, achieving efficient separation of metal debris and dust. The separated metal debris is easy to recycle and reuse, and the dust can also be collected and cleaned in a centralized manner through the collection frame, reducing resource waste and cleaning difficulty.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: A metal core edge chamfering and deburring fixture, see [link to example]. Figures 1 to 5The device includes a base 1 and a processing cylinder 6. A screw 7 passes through the side wall of the opening on the left side of the processing cylinder 6. The screw 7 is threadedly connected to the processing cylinder 6, and one end of the screw 7 located inside the processing cylinder 6 is rotatably connected to a mounting plate 701. The side of the mounting plate 701 facing the center of the processing cylinder 6 is provided with flexible bristles 703. Two limiting rods 702 are fixedly connected to the side of the mounting plate 701 facing the inner wall of the processing cylinder 6. The limiting rods 702 pass through the processing cylinder 6 and are slidably connected to the processing cylinder 6.

[0025] In the above technical solution, based on the diameter of the metal core and the processing position, the screw 7 is rotated. Because the screw 7 is threadedly engaged with the processing cylinder 6, the screw 7 pushes the mounting plate 701 to move axially along the processing cylinder 6. The limiting rod 702 slides synchronously with the mounting plate 701, restricting the rotation of the mounting plate 701 and ensuring its stable translation until the flexible bristles 703 adhere to the edge of the metal core. During processing, the flexible bristles 703 rotate with the metal core or move with the processing components, brushing away the debris generated during the chamfering and deburring process, eliminating the need for subsequent manual cleaning steps and improving processing efficiency.

[0026] Specifically, such as Figure 4 and Figure 5 As shown, a collection frame 8 is threadedly connected to the right end of the processing cylinder 6. A fixing block 802 is fixedly connected to the side of the collection frame 8 facing the inside of the processing cylinder 6. An electromagnet 803 is embedded and fixedly connected to the surface of the fixing block 802. The power supply line of the electromagnet 803 can pass through the inside of the fixing block 802 and reach the outside. A filter screen 801 is provided on the inside of the collection frame 8. A ventilation frame 9 is fixedly connected to the right surface of the collection frame 8. A fan 901 is installed on the inside of the ventilation frame 9.

[0027] In the above technical solution, before processing, the fan 901 and electromagnet 803 are started. The fan 901 draws air outward from the processing cylinder 6, creating a negative pressure that causes the debris and dust generated during processing to move towards the collection frame 8. The metal debris is attracted to the surface of the fixed block 802 by the magnetic attraction of the electromagnet 803, while the fine dust passes through the area of ​​the electromagnet 803 with the airflow and is intercepted by the filter screen 801. After processing, the fan 901 and electromagnet 803 are turned off, and the metal debris falls off. The collection frame 8 can be removed to clean the debris and dust separately, thereby achieving efficient separation of metal debris and dust. The separated metal debris is easy to recycle and reuse, and the dust can also be collected and cleaned through the collection frame 8, reducing resource waste and cleaning difficulty.

[0028] Furthermore, such as Figure 1 and Figure 4As shown, the base 1 on one side of the positioning frame 2 has an adjustment groove 101. A one-way lead screw 102 is rotatably connected to the inner side of the adjustment groove 101. A moving block 103 passes through the surface of the one-way lead screw 102, and the moving block 103 is rotatably connected to the one-way lead screw 102. The protrusion at the bottom of the processing cylinder 6 is inserted into the inner side of the moving block 103 and is detachably connected to the moving block 103 by bolts. In the above technical solution, rotating the first unidirectional lead screw 102 causes the first moving block 103 to move laterally along the adjusting groove 101, which in turn drives the top processing cylinder 6 to move synchronously. According to the requirements of the chamfering and deburring part of the metal core, the processing cylinder 6 is adjusted to the corresponding position, thus eliminating the need to disassemble and adjust the clamping state of the metal core, greatly simplifying the operation process and avoiding secondary positioning deviation.

[0029] It is worth mentioning that, such as Figure 1 and Figure 4 As shown, the top of the processing cylinder 6 is provided with a top groove 10. An inclined frame 11 is rotatably connected between the front and rear inner walls of the top groove 10. An electric push rod 12 is fixedly connected to the surface of the inclined frame 11. The telescopic end of the electric push rod 12 passes through the surface of the inclined frame 11 and is fixedly connected to the bottom block 121 located inside the processing cylinder 6. A sand block 123 is detachably connected to the bottom of the bottom block 121 by bolts. A sliding rod 122 is fixedly connected to the top surface of the bottom block 121 on one side of the electric push rod 12. The top of the sliding rod 122 passes through the inclined frame 11 above, and the sliding rod 122 is slidably connected to the inclined frame 11. The sliding rod 122 improves the stability of the movement of the bottom block 121, avoids the sand block 123 from shifting and causing deviation in chamfering accuracy, and at the same time bears the lateral force to prevent damage to the electric push rod 12.

[0030] In the above technical solution, the tilting frame 11 can adjust the tilt angle of the sand block 123 according to the chamfering angle requirements; the electric push rod 12 is activated, and its telescopic end pushes the bottom block 121 to move in the vertical direction. The slide rod 122 slides synchronously with the bottom block 121, restricting the rotation of the bottom block 121 and ensuring that the sand block 123 rises and falls stably until the sand block 123 fits the edge of the metal core; during processing, the edge of the metal core contacts the sand block 123 during the rotation process, thereby achieving chamfering and deburring; the sand block 123 is designed to be detachable, making it easy to replace sand blocks 123 of different mesh sizes to adapt to the processing of metal cores with different roughness requirements.

[0031] Furthermore, such as Figure 4As shown, a top frame 13 is provided at the top of the processing cylinder 6 on the right side of the top groove 10. A second one-way screw 131 is rotatably connected to the inner side of the top frame 13. A second moving block 132 passes through the surface of the second one-way screw 131. The second moving block 132 is threadedly connected to the second one-way screw 131. A stop rod 14 is provided between the second moving block 132 and the tilting frame 11. The two ends of the stop rod 14 are rotatably connected to the tilting frame 11 and the second moving block 132 respectively through their respective hinge seats. When the second one-way screw 131 is rotated, the second moving block 132 moves laterally along the top frame 13. The stop rod 14 pushes or pulls the tilting frame 11 to rotate around the inner wall of the top groove 10, adjusting the tilting angle of the tilting frame 11. When the tilting angle of the tilting frame 11 is determined, the self-locking characteristic of the second one-way screw 131 fixes the position of the second moving block 132, and the stop rod 14 keeps the tilting frame 11 stable.

[0032] It is worth noting that, such as Figure 1 and Figure 2 As shown, a positioning frame 2 is fixedly connected to the surface of the base 1. A turntable 3 is provided on the inner side of the positioning frame 2. The turntable 3 is rotatably connected to the positioning frame 2. A rectangular groove 301 is provided on the surface of the turntable 3. A bidirectional lead screw 4 is rotatably connected to the inner side of the rectangular groove 301. Two support blocks 401 pass through the surface of the bidirectional lead screw 4. The support blocks 401 are threadedly connected to the bidirectional lead screw 4. A crossbar 402 is fixedly connected to the side of the support block 401 facing the processing cylinder 6. Several equidistant clamping blocks 403 are fixedly connected to the opposite side of the upper and lower crossbars 402. The clamping surface of the clamping blocks 403 is provided with anti-slip pads to increase friction. The upper and lower clamping blocks 403 are alternately distributed. A servo motor 5 is fixedly connected to the surface of the base 1 on the left side of the positioning frame 2. The tail end of the transmission seat of the servo motor 5 is connected to the side frame 302 on the side wall of the turntable 3 through a coupling. The turntable 3 can rotate under the drive of the servo motor 5, thereby driving the metal core to rotate. The circumferential edge processing can be completed in one go without multiple adjustments, thus improving processing efficiency.

[0033] In the above technical solution, the servo motor 5 is started, and its transmission shaft drives the side frame 302 to rotate through the coupling. The side frame 302 synchronously drives the turntable 3 to rotate around the positioning frame 2. By adjusting the speed and direction of the servo motor 5, the rotation speed and direction of the turntable 3 can be controlled to adapt to the chamfering and deburring requirements of different metal core materials and ensure processing quality. When installing the metal core, the metal core is placed between the upper and lower crossbars 402. The bidirectional lead screw 4 is rotated. Because the threads at both ends of the bidirectional lead screw 4 are opposite, the two support blocks 401 move towards each other along the rectangular groove 301, driving the crossbar 402 and the clamping block 403 to move closer to each other synchronously until the upper and lower clamping blocks 403 are in contact with the surface of the metal core, thus fixing the metal core. During processing, the turntable 3 can rotate around the positioning frame 2, driving the metal core to rotate, and cooperating with the abrasive block 123 to complete the chamfering and deburring of the circumferential edge.
