Description

Technical Field

[0001] The invention relates to the field of workpiece slot milling, and in particular to a milling machine suitable for machining insulator hardware. Background Art

[0002] A milling machine is a machine tool that uses a rotating tool to cut workpieces. It is mainly used to process workpieces with complex shapes such as planes, grooves, formed surfaces, and gears. The connecting plate in the insulator hardware is a key metal component used to connect multiple insulators, hardware or other components in the power line. Its function is to realize the transmission and distribution of mechanical force and ensure the structural stability and electrical connection reliability of the insulator string. The holes on the surface of the connecting plate are usually used to install fasteners such as bolts and pins. The structural strength and surface treatment around the holes directly affect the reliability of the overall connection. If the connecting plate only bears load on one side (such as when a single string of insulators is suspended, the upper surface of the connecting plate is under tension), the stress concentration next to the hole mainly appears on the stress-bearing surface. At this time, only the stress-bearing surface can be milled. When the connecting plate bears bidirectional loads (such as symmetrical connection of two strings of insulators and bidirectional action of conductor tension), there is significant stress concentration on the upper and lower surfaces of the hole. Double-sided milling is required.

[0003] In the prior art, in the process of surface milling of the connecting plate in the insulator hardware, if only the surface of one side of the connecting plate is milled, only one clamping and positioning is performed, and then the surface milling is performed. If both sides of the connecting plate need to be milled, the connecting plate needs to be disassembled, the rotation of the connecting plate needs to be adjusted, and then the clamping and positioning are performed, and then the milling of the connecting plate surface can be completed, resulting in an increase in the time consumed in the entire connecting plate milling process, affecting the efficiency of the connecting plate milling.

[0013] Compared with the prior art, the present invention provides a milling machine suitable for processing insulator hardware, which has the following beneficial effects: The milling machine is suitable for processing insulator hardware. During actual use, the connecting plate is placed inside the installation frame between the clamping block and the limit block. The telescopic rod is extended to drive the connecting frame to move downward, and the milling mechanism moves together with the connecting frame. The fifth gear cooperates with the limit rack, and the second gear, the third gear and the fourth gear and the rack column are driven to drive the adjusting column to rotate. The adjusting column cooperates with the adjusting rod to adjust the clamping block to move, so that the connecting plate can be in close contact with the limit block and the limit column, and then the two clamping blocks will also be in close contact with the connecting plate to complete the clamping. When the milling mechanism is adjusted to approach the connecting plate, the clamping positioning of the connecting plate is completed, which can shorten the time required for milling the grooves on the connecting plate surface and improve the processing efficiency of milling the grooves on the connecting plate surface.

[0014] When temporarily replacing connecting plates of different specifications for surface milling, it is only necessary to place the connecting plate inside the mounting frame between the clamping block and the limit block. As the two movable columns and the clamping block are adjusted to move in the direction close to the limit block, until the surface of the connecting plate contacts the surface of the mounting frame, the two clamping blocks are also in close contact with the surface of the connecting plate, and the clamping positioning can be completed. Since the movable column and the rotating sleeve are installed by a torsion spring, the clamping block is adjusted to move at different distances for connecting plates of different specifications, the connecting frame is adjusted to a certain distance from top to bottom, the adjusting column is adjusted to a certain angle of rotation, the connecting block can cooperate with the fixed block, the closer the distance between the clamping block and the limit block, the smaller the angle of rotation of the rotating sleeve is adjusted, and vice versa, the larger the adjustment rotation angle is, and when temporarily replacing connecting plates of different specifications for surface milling, there is no need to waste time on additional adjustment of the device, thereby improving the efficiency of connecting plate surface milling.

[0015] The cam is connected to the second gear by a one-way bearing, so that the cam is in a state of rotation and the gear is moved along the cam surface, so that the cam is rotated and the gear is moved along the cam surface, so that the cam surface is rotated and the gear is moved along the cam surface, so that the cam surface is rotated and the gear is moved along the cam surface, so that the cam surface is rotated and the gear is moved along the cam surface, so that the cam surface is rotated and the gear is moved along

[0016] The milling machine is suitable for processing insulator hardware. When the adjusting column contacts the end of the adjusting rod away from the mounting frame again, the first protrusion cooperates with the first spiral groove to drive the connecting block to rotate, and the connecting block can be separated from the multiple fixed blocks. That is, after the two surfaces of the connecting plate are milled, the clamping block can be separated from the surface of the connecting plate under the elastic force of the first spring, thereby facilitating the blanking of the connecting plate.

[0017] The milling machine is suitable for processing insulator hardware. For a connecting plate with an irregular shape at the edge of the surface, when adjusting the movement of the two movable columns and the clamping block, the moving distances of the two clamping blocks are inconsistent. The adjustment column cooperates with the adjustment rod to stably drive the adjustment rod to move, and thus can stably drive the rotating sleeve and the movable rod to rotate. Although the relative movement distances between the two movable rods and the two rotating sleeves are inconsistent, the connecting block can still cooperate with multiple fixed blocks to ensure that the connecting plate with an irregular shape at the edge of the surface can be stably clamped.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 10 , a milling machine suitable for processing insulator hardware, including a milling machine base 1, an L-shaped plate 11 fixedly connected to the top upper surface of the milling machine base 1, a telescopic rod 12 symmetrically fixedly connected to the surface of the L-shaped plate 11 away from the milling machine base 1 end, a connecting frame 13 fixedly connected to the lower ends of the two telescopic rods 12 and a milling mechanism 14 cooperatively installed below the connecting frame 13, the upper surface of the milling machine base 1 is located next to the L-shaped plate 11 and is fixedly connected to a vertical plate 2, the surface of the vertical plate 2 away from the milling machine base 1 end is rotatably connected to a first rotating column 3, one end of the first rotating column 3 is fixedly connected to a first gear 4, the other end of the first rotating column 3 is fixedly connected to a mounting frame 5, the surface of the mounting frame 5 is provided with a clamping mechanism 6 for clamping connecting plates of different specifications, and a limiting mechanism 7 for limiting the rotation of the mounting frame 5 is provided below the first gear 4; The clamping mechanism 6 includes a plurality of limit blocks 61 fixedly connected to the end of the surface of the mounting frame 5 close to the vertical plate 2. The end of the surface of the mounting frame 5 away from the vertical plate 2 is symmetrically slidably connected to a movable column 62. A first spring is sleeved on the outer side of the movable column 62. One end of the first spring is fixedly connected to the movable column 62. The other ends of the two first springs are fixedly connected to the inner side of the mounting frame 5. The ends of the two movable columns 62 close to the limit blocks 61 are rotatably connected to clamping blocks 63. The limiting mechanism 7 includes a sixth gear 71 meshingly connected to the bottom of the first gear 4, the sixth gear 71 is rotatably connected to the vertical plate 2, the surface of the sixth gear 71 away from the vertical plate 2 is rotatably connected to the second rotating column 72, the surface of the second rotating column 72 is fixedly connected to the first ring 73, the surface of the first ring 73 away from the sixth gear 71 is fixedly connected to the transmission gear 75, the transmission gear 75 and the second rotating column 72 are rotatably connected through a one-way bearing, and connecting columns 74 are symmetrically fixedly connected to the bottom of the connecting frame 13, the surface of one of the connecting columns 74 is fixedly connected to the first rack, and the first rack is meshed with the transmission gear 75.

[0022] It should be noted that after the milling of one surface of the connecting plate is completed, the mounting frame 5 can be adjusted and rotated during the contraction of the telescopic rod 12, and the clamped connecting plate rotates along with the mounting frame 5. It is only necessary to control the telescopic rod 12 to be retracted and then extended at a time to limit the rotation of the mounting frame 5 again. It should be noted that since the transmission gear 75 and the second rotating column 72 are rotatably connected via a one-way bearing, when the connecting column 74 is adjusted to move in the direction of the milling machine base 1, the movement of the first rack drives the transmission gear 75 to rotate, but cannot drive the second rotating column 72 to rotate. On the contrary, it can drive the second rotating column 72 to rotate. When the connecting column 74 moves in the direction away from the milling machine base 1, the rotation of the transmission gear 75 can drive the second rotating column 72 to rotate. The first ring 73 rotates with the rotation of the second rotating column 72, and the torsion spring sleeved on the surface of the second rotating column 72 is deformed. When the telescopic rod 12 is retracted and the second protrusion 19 returns to its initial position, the arc block separates from the rectangular groove, and the mounting block can be adjusted to rotate under the action of the torsion spring. It should be noted that for the connecting plate with irregular shape at the edge of the surface, in the process of adjusting the movement of the two movable columns 62 and the clamping block 63, the movement distances of the two clamping blocks 63 are inconsistent. The adjustment column cooperates with the adjustment rod 624 to stably drive the adjustment rod 624 to move, and also to stably drive the rotating sleeve 621 and the movable rod 622 to rotate. The relative movement distances between the two movable rods 622 and the two rotating sleeves 621 are inconsistent, and the connecting block 6244 can still cooperate with multiple fixed blocks to ensure that the connecting plate with irregular shape at the edge of the surface can be stably clamped.

[0023] See also Figure 1 and Figure 2 , the end of the movable column 62 away from the clamping block 63 is installed with a rotating sleeve 621 through a torsion spring, the inner wall of the rotating sleeve 621 is slidably connected to the movable rod 622, and a cylinder 623 is rotatably connected between the two movable rods 622, and the middle part of the surface of the cylinder 623 is fixedly connected to the adjusting rod 624; See also Figure 1 、 Figure 3 、 Figure 7 and Figure 8 The surface of the connecting frame 13 is slidably connected to a rack column 131, and the end of the rack column 131 close to the L-shaped plate 11 is meshed with the second gear 132, and the end of the rack column 131 away from the L-shaped plate 11 is meshed with the third gear 133, the outer side of the second gear 132 is meshed with the fourth gear 134, and the outer side of the fourth gear 134 is meshed with the fifth gear 135. The fourth gear 134, the second gear 132, the third gear 133 and the fifth gear 135 are all rotatably connected to the connecting frame 13, and the outer side of the fifth gear 135 is meshed with a limited rack, and the limited rack is fixedly connected to the L-shaped plate 11. The surface of the second gear 132 is fixedly connected with an adjusting column, and the adjusting column and the connecting frame 13 are installed through a torsion spring, and the adjusting column is installed in cooperation with the end of the adjusting rod 624 away from the mounting frame 5; It should be noted that the adjusting rod 624 can cooperate with the adjusting column. The adjusting column rotates to drive the adjusting rod 624 to move, which in turn drives the two rotating sleeves 621 and the movable rod 622 to rotate. The torsion spring provided at the connection between the movable column 62 and the rotating sleeve 621 is deformed, and the movable column 62 and the clamping block 63 move toward the direction close to the limit block 61, thereby clamping and positioning the connecting plate. When the connecting frame 13 is adjusted to move downward, the fifth gear 135 can mesh with the limit rack, and the fifth rack is adjusted to rotate, which is driven by the fourth gear 134, the second gear 132, the rack column 131 and the third gear 133, driving the adjustment column to rotate, thereby completing the clamping and positioning of the coupling plate. When the milling mechanism 14 is adjusted to approach the coupling plate, the clamping and positioning of the coupling plate is completed at the same time, which can shorten the time required for milling the groove on the coupling plate surface and improve the efficiency of the milling process on the coupling plate surface. When the connecting plate of different specifications is temporarily replaced for surface milling, it is only necessary to place the connecting plate in the inner side of the mounting frame 5 between the clamping block 63 and the limit block 61. As the two movable posts 62 and the clamping block 63 are adjusted to move in the direction close to the limit block 61, until the surface of the connecting plate contacts the surface of the mounting frame 5, the two clamping blocks 63 also closely contact the surface of the connecting plate, and the clamping positioning can be completed. Because the movable post 62 and the rotating sleeve 621 are installed by the torsion spring, for connecting plates of different specifications, the clamping block 63 is adjusted to move at different distances, the connecting frame 13 is adjusted from top to bottom at a certain distance, the adjusting column is adjusted to rotate at a certain angle, and the connecting block 6244 can cooperate with the fixed block. The closer the distance between the clamping block 63 and the limit block 61 is, the smaller the angle of the rotating sleeve 621 is adjusted to, and vice versa. When temporarily replacing connecting plates of different specifications for surface milling, there is no need to waste time and extra adjustment of the device, thereby improving the efficiency of the connecting plate surface milling. When the telescopic rod 12 is retracted, the transmission gear 75 rotates to drive the second rotating column 72 to rotate, which is driven by the first ring 73, the second ring and the torsion spring sleeved on the surface of the second rotating column 72. When the second protrusion 19 moves to the upper end of the second spiral groove 17 and the arc block is separated from the rectangular groove, the sixth gear 71 can be adjusted to rotate, thereby driving the first gear 4 and the first rotating column 3 to rotate, adjusting the mounting frame 5 and the connecting plate to rotate, and then completing the rotation of the workpiece. The arc block cooperates with the rectangular groove to mill the other unprocessed surface of the connecting plate again. There is no need to disassemble the connecting plate and then clamp it. The time consumed in the entire connecting plate milling process is shortened, further improving the efficiency of the connecting plate surface milling processing.

[0024] See also Figure 10 and Figure 12 The surface of the adjusting rod 624 near the end of the mounting frame 5 is provided with a first spiral groove 6241, and the wall of the first spiral groove 6241 is matched with a first protrusion 6242. The outer end of the adjusting rod 624 near the mounting frame 5 is sleeved with a movable ring 6243. The first protrusion 6242 is fixedly connected to the inner side of the movable ring 6243. The surface of the movable ring 6243 near the mounting frame 5 is rotatably connected to the connecting block 6244 through a one-way bearing. The surface of the mounting frame 5 near the connecting block 6244 is provided with a There is a circular groove 6245, and the wall of the circular groove 6245 is fixedly connected to the fixing blocks evenly distributed in an annular shape. The surface of the movable ring 6243 away from the connecting block 6244 is rotatably connected to the connecting ring 6246. The surface of the connecting ring 6246 away from the movable ring 6243 is fixedly connected to the connecting spring 6247. The connecting spring 6247 is sleeved on the outside of the adjusting rod 624. The end of the connecting spring 6247 away from the connecting ring 6246 is fixedly connected to the collar, and the collar is fixedly connected to the adjusting rod 624. It should be noted that, in the process of the adjusting column being adjusted and rotated to drive the adjusting rod 624 to move toward the direction close to the mounting frame 5, the connecting block 6244 can contact the wall of the circular groove 6245, and then the adjusting rod 624 and the movable ring 6243 bracket produce relative movement, and the first protrusion 6242 and the first spiral groove 6241 produce relative movement. Since the movable ring 6243 and the connecting block 6244 rotate through the one-way bearing, at this time, the movable ring 6243 is adjusted to rotate, and the connecting block 6244 is adjusted to rotate together with the movable ring 6243. The connecting block 6244 cooperates with the fixed block to limit the rotating sleeve 621, the movable rod 622 and the adjusting rod 624 after adjustment. During the contraction of the telescopic rod 12, the adjusting column and the adjusting rod 624 are separated. Afterwards, under the action of the elastic force of the connecting spring 6247, the movable ring 6243 returns to the position where no adjustment movement is performed, and the first protrusion 6242 and the first spiral groove 6241 produce relative movement again. When the other surface of the connecting plate is milled, the adjusting column is adjusted and rotated again, and the adjusting column contacts the adjusting rod 624, driving the adjusting rod 624 to move, so that the first protrusion 6242 and the first spiral groove 6241 produce relative movement again, driving the movable ring 6243 and the connecting block 6244 to rotate, so that the connecting block 6244 and the adjusting rod 624 can rotate with the rotation of the adjusting column, and the movable column 62 and the clamping block 63 can also move in the direction away from the connecting plate under the action of the elastic force of the first spring, thereby assisting the surface milling to complete the connecting plate for cutting.

[0025] See also Figure 5 、 Figure 6 、 Figure 12 and Figure 10 , a U-shaped block is installed on the surface of the movable rod 622 at one end away from the movable column 62 through a torsion spring, and both U-shaped blocks are installed in conjunction with the adjustment rod 624; It should be noted that the setting of the U-shaped block can ensure that the adjusting rod 624 can be aligned with the position of the circular groove 6245, and ensure that the connecting block 6244 can cooperate with the circular groove 6245 when being adjusted and moved together with the adjusting rod 624, and the connecting block 6244 can also cooperate with the fixed block.

The elastic force of the second spring 53 is used to place and position the coupling plate, which is convenient for subsequent clamping.

In the process of the connecting column 74 and the connecting frame 13 being adjusted to move toward the direction close to the milling machine base 1, the second protrusion 19 and the second spiral groove 17 and the strip groove 18 all produce relative movement, thereby driving the second column 16 to rotate, and the arc block cooperates with the rectangular groove to limit the rotation of the mounting frame 5.
