Description

Technical Field

[0001] The invention relates to the technical field of insulator blank processing equipment, in particular to a suspension insulator blank automatic forming equipment. Background Art

[0002] The sanding equipment for the inner hole wall of the suspension insulator blank is an important tool for evenly coating the inner hole wall of the insulator blank with sand glaze glue and filling with glaze sand. Its main function is to ensure that a uniform insulation layer is formed on the inner hole wall of the blank, thereby improving the electrical performance and mechanical strength of the insulator and meeting the strict requirements of the power system for insulating materials. The equipment usually consists of several main parts, such as a bracket, a rotating mechanism, a coating system, a glaze sand delivery system and a control system. The rotating mechanism drives the sponge roller to rotate through a motor, so that it can move evenly along the inner hole wall of the blank, and then coat the sand glaze glue on the wall surface. The coating system is responsible for conveying the sand glaze glue to the sponge roller to ensure a continuous supply of glue, thereby achieving uniform coating. Subsequently, the glaze sand delivery system accurately delivers the sand material into the inner hole of the blank, and uses gravity and the adhesion of the glue to achieve uniform filling; For example, a cylindrical head disc-shaped suspended porcelain insulator sanding equipment disclosed in application publication number CN114261010A includes a workstation operating table, on which are arranged a plurality of workstations, each of which is provided with a blank tooling that can rotate around, and a through hole is provided in the center of the blank tooling, and the workstation operating table has at least one automatic gluing station and at least one automatic sanding station. The blank is placed horizontally with the opening of the inner hole of the blank facing downward, a sponge roller is inserted from bottom to top, and the blank rotates in a circle, so that the sand glaze glue adhered to the sponge roller can be evenly smeared on the inner wall of the inner hole of the blank. After that, the glaze sand is sprayed upwards through the sandblasting tube. Since there is no sticky sand glaze glue adhering to the end of the inner hole of the blank, the porcelain sand is only sintered to the side wall of the inner hole after firing, which ensures the uniformity of the electric field distribution on the head of the cylindrical disc-shaped suspension porcelain insulator. The existing sanding technology and equipment operation methods for the inner hole wall of the suspension insulator blank are basically the same, that is, after the coating is completed, the glaze sand delivery system delivers the sand material into the inner hole of the blank. The glaze sand is evenly filled into the inner hole through gravity and the adhesion of the glue. However, during the sandblasting process, the second lifting platform needs to drive the sand blasting tube to move downward at a uniform speed for a distance, and the moving During the process, the sand blasting tube keeps blowing. During this period, the rotation of the blank and the lifting and lowering of the sand blasting tube require a rotating drive device and a lifting device to drive them respectively. During the operation, these two driving systems need to be precisely coordinated. Since it involves the coordinated and coordinated effects of multiple moving parts of the equipment, a slight error in any component will affect the final sand material distribution effect, especially in the coordination of the lifting speed of the sand blasting tube and the rotation of the blank. If the control is not appropriate, uneven sand material distribution will easily occur, thereby affecting the sanding quality of the inner hole of the insulator blank. Summary of the invention

An axle frame 2 is fixed to the top wall of the upper sand table 1, and a multi-station reciprocating sandblasting module 3 for reciprocatingly moving in the axial direction of the inner hole of the suspension insulator blank and spraying glaze-coated sand onto the inner hole wall is installed on the outer wall of one side of the axle frame 2. A plurality of upper sand structures 4 for supplying glaze-coated sand to the multi-station reciprocating sandblasting module 3 are arranged on one side of the upper sand table 1. Check the nozzle part of the multi-station reciprocating sandblasting module 3 and connect it to an external sand supply source through a pipeline to ensure that the spraying direction, spraying amount, and spraying speed of each nozzle meet the standards; A rotary drive source 9 is installed on one side of the top end of the T-shaped frame 7 and is used to provide rotary power to the multi-station rotary clamping module 8. A telescopic transmission shaft 10 for driving the multi-station reciprocating sandblasting module 3 to work is also installed at the output end of the rotary drive source 9. A PLC control panel 11 electrically connected to the input ends of the Z-axis pneumatic lifting module 6 and the rotary drive source 9 is installed on the outer wall of one side of the upper sand table 1.

[0019] Embodiment 2, on the basis of Embodiment 1, by Figure 5 Given that, the Z-axis pneumatic lifting module 6 includes a cylinder installed at the center position of the top end of the upper sand table 1, a crossbeam 1 installed at the bottom end of the cylinder, and extension columns fixed at both ends inside the crossbeam. Crossbeam 2 is installed at the bottom ends of the two extension columns, and one end of the T-shaped frame 7 is fixedly connected to the top end of the crossbeam 2. The multi-station rotary clamping module 8 includes a plurality of end shafts 801 rotatably installed at equal intervals in a straight line at the top end of the T-shaped frame 7, chucks 803 fixed to the bottom ends of the end shafts 801, and an X-axis belt drive structure 802 for connecting the end shafts 801 in the X-axis direction. The chuck 803 is used to clamp the round head at the top end of the suspension insulator blank. The staff places the suspension insulator blank to be sandblasted inside the hole below the chuck 803 and makes the round head of the suspension insulator blank face upwards, and then uses the chuck 803 to actively clamp the round head of the suspension insulator blank to ensure firm clamping. During this process, according to the size and weight of the blank, adjust the position and clamping force of the fixture; After the chuck 803 firmly fixes the suspension insulator blank, control the Z-axis pneumatic lifting module 6 to work through the PLC control panel 11, so that the Z-axis pneumatic lifting module 6 drives the T-shaped frame 7, the multi-station rotary clamping module 8, and the rotary drive source 9 to move downward until each nozzle on the multi-station reciprocating sandblasting module 3 enters the inner hole of the suspension insulator blank; When the sand starts to come out of each nozzle of the multi-station reciprocating sandblasting module 3, one of the end shafts 801 and the chuck 803 are rotated by the rotary drive source 9, and the remaining end shafts 801, chucks 803, and suspension insulator blanks rotate together under the connection of the X-axis pulley drive structure 802, so that multiple workpieces can be processed simultaneously, and each station can perform different operations on different workpieces; The rotary drive source 9 includes a hollow machine base 901 fixed on one side of the top of the T-shaped frame 7, a stepping motor 902 installed at the top of the stepping motor 902, and a Y-axis pulley drive structure 804 installed on the output shaft of the stepping motor 902. The output shaft of the stepping motor 902 drives one of the end shafts 801 to rotate through the Y-axis pulley drive structure 804; The stepping motor 902 in the rotary drive source 9 drives one of the end shafts 801 to rotate through the Y-axis pulley drive structure 804. At the same time, the output shaft of the stepping motor 902 also drives the internal spline mother shaft 1001 and the spline sub-shaft 1002 to rotate synchronously. The spline sub-shaft 1002 provides the rotary power to the multi-station reciprocating sandblasting module 3. Through the action of the rotary drive source 9 and the telescopic transmission shaft 10, the inner hole wall of the workpiece can receive uniform sand spraying during rotation, and at the same time, the nozzle of the multi-station reciprocating sandblasting module 3 can move up and down; The telescopic transmission shaft 10 includes a spline sub-shaft 1002 rotatably installed on one side of the top of the upper sand table 1 and an internal spline mother shaft 1001 installed at the bottom end of the output shaft of the stepping motor 902 through a coupling. The top end of the spline sub-shaft 1002 extends into the interior of the internal spline mother shaft 1001. The spline sub-shaft 1002 and the internal spline mother shaft 1001 are slidably connected. The bottom end of the spline sub-shaft 1002 is connected to the input end of the multi-station reciprocating sandblasting module 3. The use of the internal spline mother shaft 1001 and the spline sub-shaft 1002 enables the rotary drive source 9 to still transmit the rotary power to the multi-station reciprocating sandblasting module 3 after the height adjustment is completed, ensuring the stability of the rotary power transmission.

[0020] Example 3, based on Example 2, by Figure 6 、 Figure 7 and Figure 8Given that, the multi-station reciprocating sandblasting module 3 includes a plurality of driven shafts 303 rotatably installed at equal intervals in a straight line inside the shaft frame 2, a worm wheel main shaft 301 rotatably installed at the other end inside the shaft frame 2, and a worm vertical shaft 302 rotatably installed at the top end of the sand loading table 1. The top end of the worm vertical shaft 302 is fixedly connected to the bottom end of the spline sub-shaft 1002. The worm vertical shaft 302 and the worm wheel main shaft 301 are meshed with each other. One end of the surface of the worm wheel main shaft 301 is equipped with a synchronous belt drive structure 304 for driving one of the driven shafts 303 to rotate. An X-axis pulley drive structure II 305 is installed between the plurality of driven shafts 303 in the X-axis direction. The other end of the driven shaft 303 is provided with an adjustable connecting rod type rotary pushing structure. The top end of the adjustable connecting rod type rotary pushing structure is installed with an end cover 308. A sandblasting nozzle 309 is installed on the outer wall of the end cover 308 close to one side of the Z-axis pneumatic lifting module 6. The sand loading structure 4 is installed at the bottom end of the sandblasting nozzle 309; The internal spline mother shaft 1001 drives the spline sub-shaft 1002, the worm vertical shaft 302, and the worm wheel main shaft 301 to rotate in turn. The worm wheel main shaft 301 drives one of the driven shafts 303 to rotate through the synchronous belt drive structure 304. In this process, the X-axis pulley drive structure II 305 plays a role in connecting the plurality of driven shafts 303 in the same X-axis direction, so that the plurality of driven shafts 303 can be driven to rotate together; The adjustable connecting rod type rotary pushing structure includes an adjustable distance plate 311 fixed to the other end of the driven shaft 303, a fish-eye connecting rod 310 hinged and installed at one end of the surface of the adjustable distance plate 311, and a guide frame 306 fixed to the top end of the sand loading table 1. A plurality of push rods 307 are slidably installed inside the guide frame 306. The bottom end of the push rod 307 is hinged to the top end of the fish-eye connecting rod 310. The top end of the push rod 307 is fixedly connected to the bottom end of the end cover 308. When the driven shaft 303 is driven to rotate, the adjustable distance plate 311 rotates around the central axis of the driven shaft 303, and the circumferential rotary motion of the adjustable distance plate 311 is converted into the Z-axis reciprocating lifting motion of the push rod 307, the end cover 308, and the sandblasting nozzle 309 through the fish-eye connecting rod 310. By precise reciprocating lifting control and nozzle action, it is ensured that the sand material can cover each area of the inner hole of the workpiece, avoiding the occurrence of missed spraying and sand accumulation phenomena, and the sand material can form a uniform coating in the axial extension direction of the inner hole of the workpiece; The sand loading structure 4 includes a flow switch valve installed at the bottom end of the sandblasting nozzle 309 and a bent pipe installed at the bottom end of the flow switch valve. The flow switch valve is installed at the bottom end of the sandblasting nozzle 309, and the inlet of the flow switch valve is connected to an external sand supply source through the bent pipe, so that the sandblasting nozzle 309 continuously sprays out sand material; A threaded rod is rotatably installed inside the distance adjusting plate 311, and a nut pair is installed at one end of the surface of the threaded rod. The nut pair is slidably connected to the distance adjusting plate 311. The bottom end of the ball eye connecting rod 310 is hinged to the outer wall of one side of the nut pair. In order to make the height lifting range of the end cover 308 and the sandblasting nozzle 309 adjustable, the staff rotates the threaded rod in the distance adjusting plate 311, drives the nut pair to move by using the threaded rod, and thus adjusts the connection point between the bottom end of the ball eye connecting rod 310 and the distance adjusting plate 311, so as to achieve the purpose of indirectly adjusting the lifting range of the end cover 308 and the sandblasting nozzle 309, and can be adjusted according to the blank parts of different sizes and shapes.

[0021] When the embodiment of the present application is in use, first, the staff places the suspension insulator blank on the multi-station rotary clamping module 8 to ensure the correct position of the workpiece. At this time, it is necessary to adjust the multi-station rotary clamping module 8 according to the specific specifications of the blank to ensure that the clamping module can accurately grasp and fix the suspension insulator blank. Before that, it is necessary to use a sponge roller adhered with sand-fused glaze glue to rotate around the inner wall of the blank's inner hole, so that a layer of sand-fused glaze glue is evenly coated on the inner wall of the blank's inner hole. Subsequently, check the nozzle part of the multi-station reciprocating sandblasting module 3 and connect it to an external sand supply source through a pipeline to ensure that the spraying direction, spraying amount, and spraying speed of each nozzle meet the standards to ensure the uniform spraying of sand; after each blank is firmly fixed on the multi-station rotary clamping module 8, the staff controls the Z-axis pneumatic lifting module 6 to work through the PLC control panel 11. The Z-axis pneumatic lifting module 6 drives the T-shaped frame 7, the multi-station rotary clamping module 8, and the rotary drive source 9 to move downward until the suspension insulator blank moves downward and the nozzle of the multi-station rotary clamping module 8 enters the inner hole of the suspension insulator blank. Adjust the height of the workpiece through the Z-axis pneumatic lifting module 6 to ensure that the distance between the nozzle and the inner hole of the workpiece is appropriate, avoiding uneven sand spraying or incomplete spraying caused by too high or too low a distance. At the same time, the rotary drive source 9 transmits the rotary power to the multi-station rotary clamping module 8, and the multi-station rotary clamping module 8 drives each workpiece to rotate self-rotationally. Through the circumferential rotation action of the blank, ensure that the sand can be evenly distributed on the inner wall of the workpiece's inner hole, thereby avoiding problems such as uneven sand walls, omission, or sand accumulation. During this process, the rotation speed and lifting height of the workpiece are precisely adjusted by the PLC control panel 11 to ensure the uniform distribution of sand; during the sand spraying process on the inner wall of the blank's inner hole, the rotary power of the rotary drive source 9 is synchronously transmitted to the multi-station reciprocating sandblasting module 3 through the telescopic transmission shaft 10, so that the nozzles of the multi-station reciprocating sandblasting module 3 move up and down reciprocally along the axial direction of the inner hole according to the set lifting trajectory and in cooperation with the self-rotation of the workpiece, ensuring that the sand is evenly sprayed onto every part of the inner hole; after the processing of the inner wall of the blank's inner hole is completed, the staff stops the sand spraying of each nozzle in the multi-station reciprocating sandblasting module 3 according to the program instructions, the multi-station rotary clamping module 8 stops rotating, and the Z-axis pneumatic lifting module 6 drives the T-shaped frame 7, the multi-station rotary clamping module 8, the rotary drive source 9, and the workpiece to return to the initial position. At this time, the workpiece has completed the sand wall processing, and the staff removes the blank from the clamping module for subsequent processing or inspection, checking the thickness and surface quality of the inner wall of each workpiece to ensure that each blank meets the standard requirements.
