Description

Technical Field

[0001] This invention relates to the field of stamping manufacturing equipment, and more specifically to a device for removing stamping burrs from marine instrument housings. Background Technology

[0002] As a key component of ship navigation and monitoring systems, the forming precision of ship instrument housings directly affects the installation stability and operational reliability of the instruments. Currently, the industry commonly uses stamping processes to achieve mass production of instrument housings, and corresponding stamping equipment is widely used. Among the existing technologies, a Chinese utility model patent with publication number CN222113205U discloses a stamping device for processing industrial instrument housings, including a stamping base. A connecting rod is fixedly connected to the upper surface of the stamping base, a top plate is fixedly connected to the upper end of the connecting rod, an electric actuator is fixedly connected to the lower surface of the top plate, a connecting plate is fixedly connected to the lower end of the electric actuator, and a stamping block is fixedly connected to the lower surface of the connecting plate.

[0003] However, during the stamping process of marine instrument case, burrs are easily generated on the edges and holes of the case due to factors such as material plastic deformation and die clearance. These burrs not only affect the smoothness of the case's appearance but may also cause abnormal clearances between components during subsequent assembly, or even scratch seals, affecting the sealing performance and service life of the instrument. Therefore, burr removal is necessary. However, existing stamping devices can only perform the stamping function of the case and lack corresponding burr removal mechanisms. After the case is stamped, manual deburring using tools such as files and sandpaper is usually required. This manual deburring method is not only labor-intensive and inefficient, making it difficult to meet the needs of mass production, but the removal effect is also greatly affected by the operator's skill level. Incomplete burr removal can easily lead to scratches on the case surface, damage to dimensional accuracy, and other problems, making it impossible to guarantee consistent processing quality. Summary of the Invention

The output end of the ring motor is provided with a drive pulley, and a driven pulley is provided at the bottom of the circular ring. The drive pulley and the driven pulley are connected by a belt.

[0011] In the aforementioned device for removing stamping burrs from marine instrument housings, a pair of tensioning pulleys for tensioning belts are provided at the bottom of the motor support plate.

[0012] In the aforementioned device for removing stamping burrs from marine instrument housings, the angle adjustment assembly includes a main frame located at the movable end of the lifting assembly. One end of the main frame has a deflection motor, and the other end has a kit. The output end of the deflection motor is connected to a shaft, which is located within the kit.

[0013] Compared with the prior art, the present invention has the following advantages: 1. In this invention, after the blank is stamped, the ejector mechanism lifts the watch case, the clamping mechanism is activated to hold the watch case, the advance cylinder drives the support frame to move toward the watch case, the positioning ring is mounted above the watch case, the lifting component drives the angle adjustment component and the blade to descend to the edge of the watch case, the position of the blade corresponds to the burr edge at the opening of the watch case, and then the angle adjustment component adjusts the angle of the blade, the rotating frame is activated, and the blade rotates around the watch case to remove the burrs on the edge of the watch case. The burr removal is completed automatically throughout the process, which effectively solves the problems of high labor intensity and low efficiency of traditional manual deburring. It can adapt to the needs of mass production, significantly improve the overall processing cycle, and ensure that the burr removal is accurate and thorough, ensuring the consistency of processing quality and the integrity of the watch case.

[0014] 2. In the clamping structure, the rotation of the driving gear drives the rotation of the driven gear, thereby realizing the opening and closing of the branch claws on both sides. The clamping of the watch case is achieved through the gear structure, which can ensure good clamping stability.

[0015] 3. In the angle adjustment assembly, the deflection motor starts, driving the shaft to rotate and the drive block to move. The drive block drives the base to deflect through the connecting rod. Since the burrs on the edge of the watch case extend in different directions, the blade angle can be adjusted to the optimal cutting angle that matches the burr extension direction. This allows for flexible adjustment of the tangential angle of the blade relative to the outer surface of the watch case, improving the cleanliness of burr removal. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0019] Example: A device for removing burrs from stamping marine instrument housings, comprising a clamping mechanism 1, a burr scraping mechanism 2, and an ejection mechanism 3, as shown in the attached diagram. Figure 1 As shown, the clamping mechanism 1 and the burr removal mechanism 2 are respectively disposed on the side of the stamping die, and the ejection mechanism 3 is disposed at the bottom of the stamping die; the ejection mechanism 3 includes an ejection cylinder 18 disposed at the bottom of the stamping die, as shown in the attached figure. Figure 2 As shown, the extended end of the ejector cylinder 18 is connected to a guide sleeve 20. The guide sleeve 20 can extend into the cavity of the stamping die. After the blank is stamped, it becomes a watch case. The watch case needs to be raised a certain distance to facilitate the removal of burrs on the edge of the watch case. When the ejector cylinder operates, its extended end drives the guide sleeve to rise, thereby lifting the watch case. To effectively prevent the surface of the watch case from being scratched, a rubber sleeve is provided at the end of the guide sleeve. The burr removal mechanism 2 includes an advance cylinder 4 located next to the stamping die, as shown in the attached figure. Figure 4 As shown, a support frame 5 is installed at the extended end of the advance cylinder 4. A positioning ring frame 6 is installed inside the support frame 5, and a rotating frame 7 is provided inside the positioning ring frame 6. A lifting component 8 is installed at the center of the rotating frame 7. Multiple longitudinally movable angle adjustment components 9 are evenly installed at the end of the rotating frame 7. A blade 10 is installed at the movable end of the angle adjustment component 9. The movable end of the lifting component 8 is connected to the angle adjustment component 9. The positioning ring frame 6 includes a ring body 21 disposed inside the support frame 5. The ring body 21 has fixed shafts 22 on both sides. The end of the fixed shaft 22 has a connecting plate 23. The connecting plate 23 is connected to the side of the support frame 5 by bolts. The connecting plate is connected to the support frame by bolts, which facilitates the disassembly and installation of the ring body.

[0020] The clamping mechanism 1 includes a transverse cylinder 11 disposed on one side of the stamping die, as shown in the attached figure. Figure 3 As shown, the extended end of the transverse cylinder 11 is connected to a vertical plate 12, and a clamping jaw 13 for fixing the watch case is installed on one side of the vertical plate 12. The clamping jaw 13 includes a clamping support plate 14 disposed on one side of the vertical plate 12. The clamping support plate 14 is provided with a driving gear 15 connected to a motor, and a set of symmetrically arranged driven gears 16 is also installed on the clamping support plate 14. The driving gear 15 meshes with the driven gear 16 on one side. The end of the clamping support plate 14 is provided with a pair of hinged branch jaws 17, and one end of the driven gear 16 is connected to the branch jaws 17. When the driving gear rotates, it meshes with the driven gear on one side, thereby driving the driven gears on both sides to rotate. One end of the driven gear is hinged to the branch jaw, thereby realizing the opening and closing of the branch jaw. The clamping of the watch case is achieved through the gear structure, which can ensure good clamping stability. To prevent excessive clamping force from the branch claws and deformation of the watch case, an elastic pad is installed on the inner side of the branch claws. A pressure sensor is installed on one side of the elastic pad. The pressure sensor and the motor are connected to the control circuit via wiring to effectively control the clamping force of the claws.

[0021] The rotating frame 7 includes a circular ring 24 embedded in the ring body 21, as shown in the attached figure. Figure 5 As shown, the inner wall of the ring body is machined with a ring-shaped groove that runs through the circumference of the ring body. The groove has a U-shaped cross-section, and the upper and lower ends of the groove are respectively provided with inwardly protruding annular limiting steps to limit axial displacement. The outer wall of the ring part is machined with a ring-shaped boss that fits the annular groove. The outer diameter of the boss and the inner diameter of the groove are clearance-fitted, and the height of the boss is the same as the depth of the groove. After the boss is embedded in the groove, it forms a preliminary embedded positioning. Multiple fixing blocks 25 are installed inside the ring part 24. A circular plate 27 is installed inside the ring part 24. The lifting assembly 8 is disposed on the lower surface of the circular plate 27. The lifting assembly includes a lifting cylinder disposed on the lower surface of the circular plate, as shown in the attached figure. Figure 6As shown, the extended end of the lifting cylinder is connected to a lifting frame, the end of which has a connecting rod. Multiple side supports 28 are evenly installed on the circular plate 27, with three sets of side supports. The side supports 28 are connected to the fixing block 25 via bolts. One end of the angle adjustment component 9 is slidably connected to the side support 28. A motor support plate 29 is installed on the outer side of the ring body 21, and a ring motor 30 is installed on the motor support plate 29. The output end of the ring motor 30 is provided with a driving pulley 31, and the bottom of the circular ring 24 is provided with a driven pulley 32. The driving pulley 31 and the driven pulley 32 are connected by a belt; in this embodiment, the belt is a toothed belt. There are three sets of fixing blocks and three sets of angle adjustment components, each corresponding to the other. The ring motor outputs power, rotating the driving pulley, which in turn drives the belt, causing the driven pulley to rotate. Since the driven pulley is fixed to the ring component, the ring component, the fixed block, and the side support rotate synchronously. The bottom of the motor support plate 29 is equipped with a pair of tensioning pulleys 33 for tensioning the belt, ensuring the stability of the belt drive. For larger burrs, they can be removed by pushing them downwards as the lifting assembly lowers the blades.

[0022] The angle adjustment component 9 includes a main frame 34 disposed at the movable end of the lifting component 8, as shown in the attached figure. Figure 7 As shown, the end of the connecting rod is connected to the main frame via a nut. One end of the main frame 34 has a deflection motor 35, and the other end of the main frame 34 has a kit 36. The output end of the deflection motor 35 is connected to a shaft 37, which is located inside the kit 36. A drive block 40 is threaded onto the shaft 37. The bottom of the kit 36 ​​has a rotatable seat 38, and the blade 10 is located at the outer end of the seat 38. The blade is locked in the seat and connected by screws to facilitate the removal of the blade. The drive block 40 is hinged to the inner end of the seat 38 via a connecting rod. One side of the main frame 34 has a limiting shaft 39, which is embedded in the slide of the side support 28. In the angle adjustment assembly, the deflection motor starts, driving the shaft to rotate and the drive block to move. The drive block drives the base to deflect via the connecting rod. Since the burrs on the edge of the watch case extend in different directions, the blade angle can be adjusted to the optimal cutting angle that matches the burr extension direction. This allows for flexible adjustment of the tangential angle of the blade relative to the outer surface of the watch case, improving the cleanliness of burr removal.

[0023] The working principle of this invention is as follows: After the ship's instrument case is stamped in the stamping die, the ejection mechanism is activated. The ejection cylinder drives the guide sleeve to extend upwards. The guide sleeve extends into the stamping die cavity and gently lifts the case, causing it to detach from the die cavity and rise to a preset height. After the ejection mechanism is in place, the clamping mechanism is activated simultaneously. The transverse cylinder pushes the vertical plate to move horizontally towards the case until the grippers move to the corresponding positions on both sides of the case. Then, the drive motor of the grippers is activated, driving the drive gear to rotate. The drive gear meshes with the driven gears on both sides, causing the two sets of driven gears to rotate synchronously in opposite directions. The driven gears drive the hinged branch claws to close relative to each other through the connecting rod, achieving precise clamping from both sides of the case. After the case is clamped and fixed, the deburring mechanism starts to operate. The advance cylinder drives the support main frame to move horizontally towards the stamping die, causing the positioning ring frame, rotating frame, and angle adjustment assembly to move synchronously closer to the case until the ring body of the positioning ring frame is coaxially sleeved above the case. At this time, the blade position... The blade is positioned at a predetermined location on the outer side of the edge where the burr on the watch case is located. After positioning, the lifting component in the center of the rotating frame is activated until the blade descends to a cutting position that matches the height of the burr on the watch case. Subsequently, the deflection motor of the angle adjustment component is activated, driving the shaft to rotate. The shaft drives the drive block to move axially along the assembly through a threaded transmission. The drive block pulls the seat body around the hinge point through a connecting rod, thereby adjusting the cutting angle of the blade so that the blade edge and the extension direction of the burr on the watch case form the optimal cutting angle, ensuring that the burr is completely removed without damaging the watch case. After the blade angle is adjusted to the correct position, the ring motor of the rotating frame is activated. The output end of the ring motor drives the drive pulley to rotate, which drives the driven pulley to rotate synchronously through a belt. The driven pulley is fixedly connected to the ring component, thereby driving the ring component, side support, and angle adjustment component to rotate circumferentially around the axis of the watch case. Multiple evenly distributed blades rotate synchronously around the edge of the watch case, scraping away the burrs on the edge of the watch case and around the holes through the cutting action of the blade edge.

Furthermore, in these embodiments, "up," "down," "left," "right," "front," and "back" represent relative positions only, not absolute positions.
