Description

Technical Field

[0001] This utility model belongs to the field of gasket processing technology, specifically a gasket chamfering device. Background Technology

[0002] Gaskets are sealing components widely used in machinery, equipment, and pipelines involved in fluid transmission. They can be used both internally and externally, playing a crucial sealing role. These gaskets are typically manufactured from metal or non-metal sheet materials through processes such as cutting, stamping, or shearing. Their main purpose is to achieve tight connections between pipes and various components of machinery and equipment. During the manufacturing process of metal gaskets, due to process variations, their sides and inner edges often produce numerous burrs. Therefore, these areas need to be chamfered to ensure quality.

[0003] According to patent CN221111057U, a gasket grinding device is disclosed, relating to the field of grinding device technology. It includes a processing table, on the upper surface of which a first servo motor is fixedly mounted. A turntable is mounted on the output end of the first servo motor, and a positioning component is provided on the turntable. An electric guide rail is fixedly mounted on the lower surface of the top plate, and an electric guide block is sleeved in the middle of the electric guide rail. A hydraulic cylinder is fixedly mounted on the lower surface of the electric guide block, and an electric grinding roller is mounted on the lower surface of the mounting plate. This invention drives a bidirectional lead screw to rotate via the output end of a second servo motor, thereby driving two lead screw sleeves and simultaneously driving two clamping plates to move away from each other, so that the two clamping plates are tightly fitted against the inner wall of the gasket, thus fixing the gasket. This device can position gaskets of different specifications, ensuring that the position of the gasket does not shift.

[0004] While the aforementioned device can secure the gasket, the frequent manual fixing and disassembly of the gaskets on the turntable, due to the batch processing of the gaskets, requires significant manpower and time, increasing workload and impacting processing efficiency. Therefore, we provide a gasket chamfering device to address these issues. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model, through the coordinated arrangement of a rotary table, base, placement table, mounting groove, moving frame, positioning wheel, guide rod, compression spring, third electric push rod, chamfering mechanism, and drive mechanism, allows un-chamfered sealing gaskets to be placed sequentially on each placement table. As the rotary table rotates, each sealing gasket is sequentially rotated and transported to the drive mechanism, where it is fixed to the placement table and rotated. Subsequently, the chamfering mechanism performs chamfering. After chamfering, the drive mechanism returns to its original position, and the rotary table continues to rotate. When the sealing gasket is on the left side, the operation of the third electric push rod pushes the processed sealing gasket to the left to fall and collect it.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 5 As shown, this utility model provides a gasket chamfering device, including a rotating table 1 and a base 8. The rotating table 1 is rotatably mounted on the base 8, which facilitates the placement of the gasket on the rotating table 1 for rotation and processing, thereby improving the chamfering efficiency of the gasket. A circular array of placement platforms 9 and a circular array of mounting slots 11 are rotatably connected to the rotating table 1. Each mounting slot 11 has a movable frame 12 elastically slidably mounted on its inner wall. Each movable frame 12 has two rotatably connected positioning wheels 15 at both ends, with the two positioning wheels 15 located on one side of the placement platform 9. With the positioning wheels 15, when the gasket is placed on the placement platform 9, it is positioned by the two positioning wheels 15, ensuring that the center of the gasket corresponds to the center of the placement platform 9. A support frame 2 is fixed to the side of the base 8. A blowing mechanism is set in the middle of the rotating table 1. The blowing mechanism can blow away the debris on the rotating table 1 to prevent it from accumulating on the rotating table 1 and to ensure the cleanliness of the sealing gasket during subsequent collection. A chamfering mechanism and a drive mechanism are set on the support frame 2. With the chamfering mechanism, the sealing gasket on the placement table 9 can be chamfered automatically. The drive mechanism makes the sealing gasket rotate on the placement table 9, which greatly improves the chamfering efficiency of the sealing gasket and realizes the automation of the chamfering process of the sealing gasket, reducing the labor burden of personnel. The machinery, parts and equipment in this device all adopt conventional models in the existing technology. In addition, the circuit connection adopts conventional connection methods in the existing technology, which will not be described in detail here.

[0027] like Figure 1 and Figure 3As shown, a fixed cover 18 is fixedly connected to the bottom surface of the base 8, and several support columns 13 are fixedly connected to the bottom surface of the fixed cover 18. There are guide rails on the base 8, and the bottom end of each support column 13 slides in the guide rail on the base 8 through rollers. With the above structure, the rotary table 1 is guaranteed to rotate stably on the base 8, thereby improving the chamfering efficiency of the sealing gasket.

[0028] like Figure 2 and Figure 3 As shown, a second motor 19 is installed on the base 8. A gear 20 is fixedly connected to the output end of the second motor 19. The inner wall of the fixed cover 18 is fixedly connected with teeth arranged at equal intervals, and the gear 20 meshes with the teeth. With the above structure, the second motor 19 can drive the gear 20 to rotate, so that the gear 20 can move the teeth on the fixed cover 18, and finally achieve the rotation effect of the rotating table 1 on the base 8.

[0029] like Figure 1 and Figure 3 As shown, the blowing mechanism includes a blower 21, which is installed in the middle of the base 8. The output end of the blower 21 is connected to a blowing pipe 10, and the top end of the blowing pipe 10 passes through the rotating table 1 and extends to the rear. The middle part of the rotating table 1 is rotatably connected to the surface of the blowing pipe 10. With the above structure, when the chamfered sealing gasket moves to the rear by the rotation of the rotating table 1, the blower 21 can be started to blow air to the rear of the rotating table 1, thereby blowing off the debris scattered on the rotating table 1. The rotating table 1 can also maintain stability when rotating through the blowing pipe 10.

[0030] like Figure 1 and Figure 4 As shown, a guide rod 16 is fixedly connected to the inner wall of each mounting groove 11, and the movable frame 12 is sleeved on the guide rod 16. A compression spring 17 is sleeved on the surface of each guide rod 16, and the two ends of the compression spring 17 are fixedly connected to the surface of the movable frame 12 and the inner wall of the mounting groove 11, respectively. With the above structure, the movable frame 12 has the effect of automatic reset, making the movable frame 12 slide more smoothly in the mounting groove 11.

[0031] like Figure 4 As shown, each guide rod 16 has an external thread on its surface, and a blower pipe 10 is threaded onto the surface of the guide rod 16. The blower pipe 10 is in contact with the movable frame 12. With the setting of the blower pipe 10, the position of the movable frame 12 in the mounting groove 11 can be easily adjusted, thereby adjusting the distance between the two positioning wheels 15 and the placement platform 9. This is suitable for positioning sealing gaskets of different sizes.

[0032] like Figure 4As shown, a third electric push rod 22 is mounted on the base 8 via a bracket, and the telescopic end of the third electric push rod 22 is adapted to the bottom end of the movable frame 12. With the setting of the third electric push rod 22, when the chamfered sealing gasket moves to the left side by the rotation of the rotary table 1, the operation of the third electric push rod 22 can push the corresponding movable frame 12 to the left, so that the two corresponding positioning wheels 15 push the sealing gasket on the placement table 9 to the left. After the third electric push rod 22 retracts, the movable frame 12 automatically resets under the elastic force of the compression spring 17, so as to facilitate the subsequent positioning and placement of the un-chamfered sealing gasket, thereby realizing the automatic unloading of the sealing gasket without the need for manual material handling.

[0033] like Figure 1 and Figure 2 As shown, the chamfering mechanism includes a first electric push rod 3, which is installed on the side of the stand 2. A chamfering cutter 6 is installed on the telescopic end of the first electric push rod 3. The chamfering cutter 6 is easy to disassemble at the telescopic end of the first electric push rod 3, and the disassembly and assembly structure is a mature existing technology, which will not be described in detail here. This allows for chamfering of gaskets of different thicknesses. With the first electric push rod 3 and the chamfering cutter 6 in place, when the gasket on the rotary table 1 rotates to the left side of the chamfering cutter 6, it is fixed on the placement table 9 by the drive mechanism and rotated. Then, the first electric push rod 3 can be used to control the chamfering cutter 6 to chamfer the side of the gasket.

[0034] like Figure 1 , Figure 2 and Figure 5 As shown, the driving mechanism includes a second electric push rod 4, the telescopic end of which is fixedly connected to a first motor 5, and the output end of the first motor 5 is fixedly connected to a pressing plate 7. The diameter of the pressing plate 7 is smaller than the diameter of the placement table 9. With the above structure, when the sealing gasket is placed on the placement table 9, the second electric push rod 4 is used to move downward to drive the first motor 5 and the pressing plate 7 to descend, thereby pressing and fixing the sealing gasket with the pressing plate 7. Then, the operation of the first motor 5 is started to make the pressing plate 7 drive the sealing gasket to rotate on the placement table 9, which facilitates the subsequent chamfering.

[0035] like Figure 1 , Figure 2 and Figure 5As shown, four insert rods 23 are fixedly connected to the bottom surface of the extrusion plate 7, and the bottom end of the insert rods 23 is conical. A cross-shaped frame 14 is fixedly connected to the inner wall of each placement platform 9. With the cooperation of the insert rods 23 and the cross-shaped frame 14, the insert rods 23 can be blindly inserted into the placement platform 9. When the insert rods 23 rotate with the extrusion plate 7, the placement platform 9 also rotates. Since the bottom end of the insert rods 23 is conical and the surface of the cross-shaped frame 14 is cylindrical, the bottom end of the insert rods 23 will slide to one side even when it contacts the surface of the cross-shaped frame 14, so as not to cause extrusion damage to the cross-shaped frame 14. When the extrusion plate 7 extrudes and fixes the sealing gasket on the placement platform 9, the four insert rods 23 will also be inserted under the cross-shaped frame 14. When the extrusion plate 7 rotates, the insert rods 23 will be used to rotate the cross-shaped frame 14, which is beneficial to the rotational stability of the sealing gasket between the placement platform 9 and the extrusion plate 7, thereby ensuring the stability of the sealing gasket when chamfering.

[0036] The working principle and usage process of this utility model are as follows: First, the sealing gasket to be chamfered is placed on the placement platform 9 in front of the rotary table 1, and positioned by the corresponding two positioning wheels 15 to ensure the accuracy of the placement of the sealing gasket. Then, the rotary table 1 is controlled to rotate counterclockwise by the operation of the second motor 19. While rotating, the remaining sealing gaskets can be placed on the remaining placement platforms 9. When the sealing gasket reaches below the extrusion plate 7, the rotation of the rotary table 1 is stopped. Then, the second electric push rod 4 is activated to press and fix the sealing gasket on the placement platform 9 by the extrusion plate 7. At the same time, the insertion rod 23 is also inserted into the middle of the placement platform 9 and located below the cross-shaped frame 14. The first motor 5 is turned on to drive the sealing gasket and the placement platform 9 to rotate. When the sealing gasket rotates, it will push the positioning wheels 15 to rotate together. Then, the chamfering is controlled by the operation of the first electric push rod 3. The cutting tool 6 bevels the gasket. After the process is complete, the electrical components are returned to their original positions, and the rotary table 1 is rotated. When the beveled gasket reaches the rear of the rotary table 1, the blower 21 is activated to blow air towards the rear of the rotary table 1, thereby blowing off the debris scattered on the rotary table 1. Then, when the gasket is on the left side, the operation of the third electric push rod 22 pushes the corresponding moving frame 12 to the left, causing the two corresponding positioning wheels 15 to push the gasket on the placement table 9 to the left. After the third electric push rod 22 retracts, the moving frame 12 automatically resets under the elastic force of the compression spring 17, so that the unbeveled gasket can be positioned and placed later. This achieves automatic unloading of the gasket without the need for manual handling, thus making the beveling process of the gasket more automated and eliminating the need for tedious manual operation.
