Description

Technical Field

[0001] The invention relates to the technical field of casting molding equipment, and in particular to a blank repairing device for insulator production. Background Art

[0002] As a component used for support and insulation in the power system, the surface quality and dimensional accuracy of insulators directly affect the stability and safety of power transmission. Traditional blanking methods mostly rely on manual operations, which are inefficient and difficult to ensure consistency in quality. Modern insulator production is gradually developing in the direction of automation and high precision, and various blanking devices have emerged. These devices are designed to trim the insulator blank through mechanized operations, remove excess parts, and make the insulator meet the specified size and surface quality requirements. Automated blanking devices can not only improve production efficiency, but also reduce errors caused by manual operations, improve product yield, and meet large-scale, high-quality production needs.

[0003] Existing insulator blank repairing devices have obvious defects in power drive and action coordination. Most existing equipment uses multiple independent power sources to drive blank clamping, blank rotation and blank repair tool movement respectively. This not only increases the manufacturing cost and energy consumption of the equipment, but also makes the equipment structure complicated and occupies a larger space. The coordinated control of multiple power sources is difficult, and it is easy to have uncoordinated coordination between the various actions. For example, when the blank clamping and the blank repairing tool feeding are carried out at the same time, the blank may be repaired without stable clamping due to the difference in response speed of different power sources, which seriously affects the blank repair accuracy and even causes damage to the blank. Since each power source works independently, it is difficult to achieve accurate linkage of all actions, resulting in a high rate of defective products. Summary of the invention

[0008] Furthermore, the tooth plate is plugged into the horizontal platform, and the arc clamping plate is plugged into the blank repairing platform, so that different applicable accessories can be replaced according to insulators of different sizes.

[0009] Furthermore, the inner wall of the arc-clamping auxiliary plate is rollingly connected with a ball to reduce the friction force of the arc-clamping plate when it rotates with the blank repairing turntable.

[0014] The beneficial effects of the present invention are as follows: 1. This solution is driven by a single servo motor to achieve the coordinated operation of the insulator blank clamping, rotation and blank repair tool movement. The transmission structure is used to achieve mutual linkage and each performs its own duties. During the blank clamping process, the servo motor rotates to control the movement of the clamping arc plate through multi-stage transmission to ensure that the blank is stably clamped, and drives the blank repair turntable to rotate and the blank repair tool to translate through transmission, so as to achieve clamping first and then blank repair. The coordination degree and processing consistency between the various actions are high, which reduces the coordination problems between power sources, reduces the probability of equipment failure and defective products, and reduces the manufacturing cost of the equipment and energy consumption compared to the traditional blank repair device with multiple power sources.

[0015] 2. The two clamping arc plates can slide by rotating the drive shaft, and the clamping arc plates can be replaced, so as to clamp insulator blanks of different sizes. The ball bearings can reduce the friction force, and the clamping arc plates and the clamping arc plates can work closely together to ensure that the blank is firmly fixed during the blank repair process, effectively improving the blank repair accuracy and reducing the defective rate caused by loose blanks.

[0016] 3. The turntable linkage assembly realizes the control of the speed of the blank repair turntable through multi-stage transmission. The power of the servo motor is transmitted to the central shaft through the drive shaft, long spur gear, turntable linkage spur gear, turntable linkage shaft, first bevel gear and second bevel gear to drive the blank repair turntable to rotate. This transmission method can flexibly adjust the speed of the blank repair turntable according to the requirements of the blank repair process. When repairing insulators of different materials and shapes, the appropriate speed can be selected to avoid damage to the blank due to improper speed.

[0017] 4. The second external thread on the drive shaft is connected to the thread of the tool holder translation frame to achieve accurate control of the moving distance of the tool holder translation frame each time, and the blanking tool is connected to the tool mounting seat through a screw, which is convenient for replacing different types of blanking tools according to insulators of different sizes and shapes. In actual production, when it is necessary to perform blanking on different parts of the insulator, the tool position can be quickly adjusted and the tool can be replaced, which greatly improves the flexibility and adaptability of blanking and meets the diverse blanking needs.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The present invention will be further described below in conjunction with the accompanying drawings: Example 1 A blank repairing device for insulator production, such as Figure 1 and Figure 6 As shown, a trimming platform 2 is installed on the trimming base 1 to make it stand firmly. A central shaft 3 is installed in the middle of the trimming base 1, and it is ensured that the central shaft 3 is smoothly connected to the trimming base 1. A trimming turntable 4 is fixed on the top of the central shaft 3, and the upper end of the trimming turntable 4 passes through the trimming platform 2 and is rotatably connected to the trimming platform 2, providing a basis for subsequent rotation trimming of the blank.

[0023] like Figures 1 to 4 As shown, in this embodiment, a servo motor 13 is installed on the top of the blank repairing base 1, and the output end of the servo motor 13 is connected to the driving shaft 14 to ensure stable power transmission. A horizontal platform 15 slidably connected to the blank repairing base 1 is set on the rear side of the driving shaft 14, and two booster plates 51 are set on both sides of the horizontal platform 15. Two sections of first external threads 52 are provided on the driving shaft 14, which are respectively threadedly connected to the two booster plates 51, so that when the driving shaft 14 rotates, the booster plates 51 can be driven to move axially. An auxiliary clamping arc plate 53 is set on the side away from the two clamping arc plates 10. The outer wall of the auxiliary clamping arc plate 53 is fixed with a long plate 54, and a clamping linkage shaft 55 is installed to pass through the two long plates 54. The clamping linkage shaft 55 has two opposite thread sections, which are respectively threadedly connected to the two long plates 54. When the clamping linkage shaft 55 rotates, the two clamping arc plates 10 can be driven to slide closer to each other through the auxiliary clamping arc plate 53. A worm gear 56 is fixed on the outer side of the driving shaft 14, and the worm gear 56 passes through the blank repairing platform 2. A worm 57 meshing with the worm gear 56 is installed below the worm gear 56. A clamping linkage spur gear 58 is fixed on the outer side of the worm gear 56, and a tooth plate 59 is arranged on the top of the horizontal platform 15. During the movement of the horizontal platform 15, the tooth plate 59 can mesh with the clamping linkage spur gear 58 to realize the linkage between the clamping action and the movement of the horizontal platform 15.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, two groups of first reset components are arranged on both sides of the horizontal platform 15, and the first reset components include a first positioning plate 81 fixed to the blank repair base 1, and the first positioning plate 81 is fixed to the side wall of the horizontal platform 15 near the first compression spring 82, and the two groups of first reset components are respectively located at the head end and the tail end of the movement of the horizontal platform 15, so that the booster plate 51 will not completely disengage from the first external thread 52, and the booster plate 51 can move in the reverse direction and reset when the driving shaft 14 reverses. The tooth plate 59 is plugged into the horizontal platform 15, and the clamping arc plate 10 is plugged into the blank repair platform 2, which is convenient for replacing different applicable accessories according to insulators of different sizes. The inner wall of the auxiliary clamping arc plate 53 is rolled and connected with the ball 16 to reduce the friction of the clamping arc plate 10 when it rotates with the blank repair turntable 4.

[0025] Example 2 On the basis of the above-mentioned embodiment 1, Figure 1 , Figure 3 and Figure 6 As shown, an extension plate 61 is fixed on the side wall of the horizontal platform 15, and a turntable linkage shaft 62 is rotatably connected to the outer wall of the extension plate 61, and a turntable linkage spur gear 63 is fixed on the outer side of the turntable linkage shaft 62. A long spur gear 64 is fixed on the outer side of one end of the driving shaft 14 close to the central axis 3 to ensure that the turntable linkage spur gear 63 can mesh with the long spur gear 64. A first bevel gear 65 is fixed at the end of the turntable linkage shaft 62, and a second bevel gear 66 that can mesh with the first bevel gear 65 is fixed on the outer side of the central axis 3. When the extension plate 61 moves with the horizontal platform 15 to the point where the first bevel gear 65 meshes with the second bevel gear 66, the turntable linkage spur gear 63 is in meshing state with the long spur gear 64, so that the driving shaft 14 can drive the blank repairing turntable 4 to rotate after the clamping is completed, thereby driving the insulator blank to rotate.

[0026] Example 3 Based on the above embodiment 2, Figure 1 , Figure 5 and Figure 6 As shown, a tool seat translation frame 71 is installed on the top of the blank repair base 1, so that it can slide on the blank repair base 1 and pass through the blank repair platform 2. The blank repair platform 2 is provided with a through slot for the tool seat translation frame 71 to slide. The driving shaft 14 passes through the tool seat translation frame 71, and a second external thread 72 is provided on the driving shaft 14. The tool seat translation frame 71 is threadedly connected to the driving shaft 14 through the second external thread 72, and the thread rotation direction of the second external thread 72 is opposite to that of the first external thread 52, so that the tool seat translation frame 71 can be translated when the driving shaft 14 rotates, and the blank repair tool 12 is close to or away from the insulator blank.

[0027] like Figure 1 and Figure 6As shown, in this embodiment, two sets of second reset components are arranged on both sides of the second external thread 72, and the second reset components include a second positioning plate 91 fixed to the blank repair base 1, and the second compression spring 92 is fixed to the side wall of the second positioning plate 91 close to the second external thread 72. The two sets of second reset components are respectively located at the head end and the tail end of the movement of the tool seat translation frame 71, so that the tool seat translation frame 71 will not completely disengage from the second external thread 72, and the tool seat translation frame 71 can move in the reverse direction and reset when the driving shaft 14 is reversed. The blank repair tool 12 is connected to the tool mounting seat 11 through a screw rod, which is convenient for replacing different blank repair tools 12 according to insulators of different sizes.

[0028] A protective cover frame may be installed on the top of the blank repairing base 1 to protect the components between the blank repairing platform 2 and the blank repairing base 1 to prevent material chips from splashing onto the components during the blank repairing process. An outer cover is provided on the outside of the worm gear 56 to protect the worm gear 56 to prevent material chips from falling onto the worm gear 56 and affecting its normal operation.

[0029] The working principle of the present invention is as follows: Blank clamping: Start the servo motor 13, and the servo motor 13 drives the driving shaft 14 to rotate. Since the two sections of the first external thread 52 on the driving shaft 14 are respectively threadedly connected with the two booster plates 51, when the driving shaft 14 rotates, the two booster plates 51 will move axially along the driving shaft 14. When the horizontal platform 15 moves, the toothed plate 59 on its top engages with the clamping linkage spur gear 58, driving the worm gear 56 to rotate, thereby rotating the clamping linkage shaft 55. The two opposite thread sections on the clamping linkage shaft 55 are respectively threadedly connected with the two long plates 54, so when the clamping linkage shaft 55 rotates, the two long plates 54 drive the auxiliary clamping arc plate 53 and the clamping arc plate 10 to slide in the opposite direction, thereby achieving the clamping or loosening action of the insulator blank. When the horizontal platform 15 needs to be reset, the first compression spring 82 of the first reset assembly will push the booster plate 51, so that the horizontal platform 15 can be threadedly connected with the first external thread 52, so that it can smoothly move in the opposite direction and reset when the driving shaft 14 reverses, ensuring the normal cycle of the clamping structure.

[0030] The tooth plate 59 is plugged into the horizontal platform 15, and the arc clamping plate 10 is plugged into the blank repairing platform 2, so as to facilitate the replacement of different applicable accessories according to insulators of different sizes. The inner wall of the arc clamping plate 53 is connected with the rolling ball 16 to reduce the friction of the arc clamping plate 10 when rotating with the blank repairing turntable 4.

[0031] The blank repairing turntable 4 rotates: When the horizontal platform 15 moves, the extension plate 61 moves accordingly. When the extension plate 61 moves to the point where the first bevel gear 65 meshes with the second bevel gear 66, the turntable linkage spur gear 63 and the long spur gear 64 are already in meshing state (at this time, the booster plate 51 close to the center axis 3 compresses the first compression spring 82 at this end, and the movement of the horizontal platform 15 just stops). The rotation of the drive shaft 14 drives the long spur gear 64 to rotate, and the long spur gear 64 drives the turntable linkage spur gear 63 to rotate, thereby rotating the turntable linkage shaft 62, and the first bevel gear 65 at the end of the turntable linkage shaft 62 drives the second bevel gear 66 to rotate, thereby rotating the center axis 3, realizing the rotation of the blank repairing turntable 4, and driving the clamped insulator blank to rotate.

[0032] The trimming tool 12 translates: when the drive shaft 14 rotates, since the tool holder translation frame 71 is threadedly connected to the drive shaft 14 through the second external thread 72, and the thread rotation direction of the second external thread 72 is opposite to that of the first external thread 52, the rotation of the drive shaft 14 causes the tool holder translation frame 71 to translate on the trimming base 1 in the direction opposite to the horizontal platform 15, and the trimming tool 12 gradually approaches the insulator blank. When the trimming turntable 4 drives the insulator blank to rotate, the trimming tool 12 performs the trimming operation, and the limit position of the movement of the tool holder translation frame 71 is when it moves to compress the second compression spring 92 near one end of the central axis 3. When the drive shaft 14 reverses, the second compression spring 92 of the second reset assembly will push the tool holder translation frame 71, so that the tool holder translation frame 71 can be threadedly connected to the second external thread 72, so that it can smoothly move in the opposite direction and reset when the drive shaft 14 reverses.

[0033] The trimming tool 12 is connected to the tool mounting seat 11 through a screw rod, so that different trimming tools 12 can be replaced according to insulators of different sizes, thereby meeting the adjustment requirements of tool positions for different trimming processes.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
