Description

Technical Field

[0001] This invention relates to the field of locomotive leader rod processing technology, specifically a grooving device for processing locomotive leader rod locking grooves. Background Technology

[0002] The locomotive head lever is an important mechanical component used to connect the locomotive head and wheels, enabling the locomotive to steer and control; its locking slot is mainly to prevent the locomotive from detaching from the lever during operation.

[0003] In existing technologies, clamping assemblies are typically used to fix the locomotive's leading edge rod before slotting it. Because the locomotive's leading edge rod is cylindrical, existing clamping mechanisms usually use point-to-point contact for positioning, which can easily lead to slight misalignment of the leading edge rod after processing stress. This affects the slotting accuracy of the locking groove and reduces the product yield. Therefore, we propose a slotting device for processing the locking groove of a locomotive leading edge rod. Summary of the Invention

[0004] The purpose of this invention is to provide a grooving device for machining the locking groove of a locomotive leader rod, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grooving device for machining a locking groove on a locomotive leader rod, comprising a support and a grooving tool fixedly connected to one side thereof, and a locomotive leader rod body. One end of the locomotive leader rod body is fixedly connected to a rudder, and both ends of the rudder are respectively provided with connecting holes. A worktable is fixedly connected to the top of the support, and a second straight plate is fixedly connected to the top of the support, with a positioning hole for the locomotive leader rod body to pass through inside. Two positioning rods symmetrical to the connecting holes are evenly fixedly connected to one side of the second straight plate. A first support plate is fixedly connected to the side of the worktable away from the second straight plate, and the top of the first support plate is constructed with an extrusion groove for placing the locomotive leader rod body. A pressure plate is provided above the first support plate. A transmission assembly for driving the pressure plate to move is constructed on the top of the worktable. Multiple abutment blocks that can abut against the inside of the connecting holes are respectively provided inside the two positioning rods. A driving assembly for driving the multiple abutment blocks to move away from each other is provided inside the second straight plate. A linkage mechanism for opening the driving assembly is provided at the bottom of the pressure plate.

[0006] By adopting the above scheme, a linkage mechanism is set up to enable the drive component and the transmission component to cooperate with each other, thereby achieving synchronous clamping and fixing of both ends of the locomotive head rod body and improving the accuracy of the slotting of the locomotive head rod body.

[0007] Preferably, the transmission assembly includes a drive motor fixedly connected to the top of the worktable, and a screw fixedly connected to the output end of the drive motor, the screw being threadedly connected to the pressure plate.

[0008] By adopting the above scheme, the transmission assembly can cause the pressure plate to move downwards and contact the top surface of the locomotive's front rod body, thus fixing it in place.

[0009] Preferably, the drive assembly includes rotating rods rotatably connected to the interiors of two positioning rods, with turntables uniformly fixedly connected to the outer surfaces of the two rotating rods, and multiple first cranks hinged to one side of each of the two turntables. The ends of the multiple first cranks that are far apart from each other are respectively hinged to multiple abutment blocks, and through holes are provided inside the interiors of the two positioning rods for the multiple abutment blocks to slide.

[0010] By adopting the above scheme, a driving component is provided to facilitate the transmission of multiple contact blocks, causing them to diverge and then contact the connecting hole to fix them.

[0011] Preferably, the outer surfaces of the two rotating rods are respectively fixedly connected with a driven wheel and a driving wheel, and the driving wheel is connected to the driven wheel by a belt.

[0012] By adopting the above scheme, the drive wheel and the driven wheel are connected by a belt so that multiple abutment blocks in the two positioning rods run synchronously, thereby strengthening the limiting force on the connection hole.

[0013] Preferably, the rotating rod with the driving wheel fixedly connected to its outer surface has a driven gear fixedly connected to its outer surface, the second straight plate has a rack slidably connected to the inside of the second straight plate that meshes with the driven gear, the second straight plate has a second air cylinder fixedly connected to the inside of the second air cylinder, the second air cylinder has a second piston rod slidably connected to the inside of the second piston rod and the top of the second piston rod is fixedly connected to the rack.

[0014] By adopting the above scheme, the pneumatic energy converted by the linkage mechanism can be easily absorbed and utilized to drive the drive component to start by setting up the interaction between the driven gear and the rack.

[0015] Preferably, the linkage mechanism includes three first piston rods fixedly connected to the bottom of the pressure plate, and three first air cylinders adapted to them are fixedly connected to the top of the worktable and directly below the three first piston rods, an air pipe is fixedly connected inside the worktable, and a connecting pipe communicating with the air pipe is connected to the bottom of the three first air cylinders respectively.

[0016] By adopting the above scheme, the potential energy generated by the movement of the pressure plate can be converted through the linkage mechanism and then used by the drive components.

[0017] Preferably, the end of the trachea away from the connecting pipe is connected to a gas delivery pipe that is connected to the second gas cylinder.

[0018] By adopting the above scheme, a gas delivery pipe is connected to the second gas cylinder to facilitate the delivery of gas.

[0019] Preferably, the top of the workbench has an empty slot for storing waste chips, the empty slot is fixedly connected to a support member, the top of the support member is fixedly connected to a fixing ring, and the fixing ring and the support member are rotatably connected together by twelve blades.

[0020] Using the above scheme, when the twelve blades are arranged horizontally, the empty slots of the workbench can be sealed, thereby preventing the external airflow from entering and causing the internal waste to be blown away by the wind.

[0021] Preferably, the outer surface of the fixed ring is uniformly rotatably connected to twelve connectors, and the two closest to each other of the twelve connectors are rotatably connected to a second crank.

[0022] By adopting the above scheme, in order to further control the opening and closing of the twelve blades,

[0023] Preferably, the top of the air pipe is connected to a third air cylinder, the interior of the third air cylinder is fitted with a third piston rod, and the top of the third piston rod is fixedly connected to a straight groove plate. One side of one of the connectors is fixedly connected to a connecting plate, and one side of the connecting plate is rotatably connected to a limiting rod that is slidably connected to the straight groove plate.

[0024] By adopting the above scheme, the gas in the air pipe can be divided by the cooperation of the third piston rod and the third air cylinder, so that the airflow generated by the movement of the first piston rod can be reused, thereby realizing multiple uses of one drive and improving its multifunctionality.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] This invention features a positioning hole through which the locomotive leader rod body passes and is positioned at the top of the extrusion groove. Simultaneously, the downward movement of the pressure plate abuts against the locomotive leader rod body, causing force to be applied to the top of the locomotive leader rod body, thus suppressing any misalignment in the left-right direction. A positioning rod is also provided, allowing the connecting hole to fit onto its outer surface, thereby limiting the rolling of the locomotive leader rod body and stably fixing it between the extrusion groove and the second straight plate. A linkage mechanism allows the drive and transmission components to cooperate, achieving synchronous clamping and fixing of both ends of the locomotive leader rod body, improving the accuracy of the grooving. Twelve blades can be used to seal or open / close the empty groove, allowing for flexible use. When grooving the locomotive leader rod body, the blades can be opened / closed to allow processing waste to enter the empty groove of the worktable; when processing stops, they can be closed to prevent waste from being blown away by the wind. Furthermore, the cooperation of a third piston rod and a third air cylinder can divide the gas in the air pipe, allowing the airflow generated by the movement of the first piston rod to be reused, thus achieving multiple uses with a single drive and improving its multi-functionality.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1

[0040] Please see Figure 1-3 This invention provides a technical solution: a grooving device for machining a locomotive steering rod locking groove, comprising a support 100 and a grooving tool 101 fixedly connected to one side thereof, and a locomotive steering rod body 103. A rudder 104 is fixedly connected to one end of the locomotive steering rod body 103, and connecting holes 105 are respectively provided at both ends of the rudder 104. A worktable 102 is fixedly connected to the top of the support 100, and a second straight plate 300 is fixedly connected to the top of the support 100, with positioning holes 303 inside for the locomotive steering rod body 103 to pass through. Two positioning holes symmetrical to the connecting holes 105 are evenly fixedly connected to one side of the second straight plate 300. A first support plate 201 is fixedly connected to the side of the worktable 102 away from the second straight plate 300. The top of the first support plate 201 is constructed with an extrusion groove 202 for placing the locomotive head rod body 103. A pressure plate 200 is provided above the first support plate 201. The top of the worktable 102 is constructed with a transmission assembly that drives the pressure plate 200 to move. By providing a positioning rod 301, the connecting holes 105 at both ends of the rudder 104 can be limited and fixed, thereby preventing the locomotive head rod body 103 from rotating during processing. The transmission assembly can cause the pressure plate 200 to move down and abut against the top surface of the locomotive head rod body 103 to fix it.

[0041] To facilitate the fixing of the locomotive head rod body 103, the transmission assembly includes a drive motor 204 fixedly connected to the top of the workbench 102, and a screw 203 fixedly connected to the output end of the drive motor 204, which is threadedly connected to the pressure plate 200.

[0042] In summary, by providing a positioning hole 303 for the locomotive leader rod body 103 to pass through and be placed at the top of the extrusion groove 202, and by the downward movement of the pressure plate 200 against the locomotive leader rod body 103, the top of the locomotive leader rod body 103 is subjected to force, thereby suppressing its misalignment in the left and right directions. At the same time, by providing a positioning rod 301 so that the connecting hole 105 is fitted onto its outer surface, the rolling of the locomotive leader rod body 103 can be restricted, thereby stably fixing it between the extrusion groove 202 and the second straight plate 300.

[0043] Example 2

[0044] Please see Figure 4 and Figure 8 as well as Figure 10 To further improve the clamping and fixing of the locomotive headstock body 103, so that both ends of it are clamped under force, thereby improving its processing accuracy, multiple abutment blocks 302 that can abut against the inside of the connecting hole 105 are respectively provided inside the two positioning rods 301. The second straight plate 300 is provided with a drive assembly that drives the multiple abutment blocks 302 to move away from each other. The drive assembly includes rotating rods 304 that are rotatably connected to the inside of the two positioning rods 301. Turntables 305 are uniformly fixedly connected to the outer surfaces of the two rotating rods 304. Multiple first cranks 306 are hinged to one side of each of the two turntables 305. The ends of the multiple first cranks 306 that move away from each other are respectively hinged to the multiple abutment blocks 302. Through holes are opened inside the two positioning rods 301 for the multiple abutment blocks 302 to slide. The drive assembly facilitates the transmission of the multiple abutment blocks 302, so that they diverge and abut against the connecting hole 105 to fix them.

[0045] Furthermore, the outer surfaces of the two rotating rods 304 are respectively fixedly connected to a driven wheel 312 and a driving wheel 311. The driving wheel 311 and the driven wheel 312 are connected by a belt. The belt connection between the driving wheel 311 and the driven wheel 312 enables the multiple abutment blocks 302 in the two positioning rods 301 to run synchronously, thereby strengthening the limiting force on the connecting hole 105.

[0046] like Figure 8 and Figure 9 As shown, a rotating rod 304 with a driving wheel 311 is fixedly connected to its outer surface, and a driven gear 307 is fixedly connected to its outer surface. A rack 308 that meshes with the driven gear 307 is slidably connected inside the second straight plate 300. A second air cylinder 310 is fixedly connected inside the second straight plate 300. A second piston rod 309 is slidably connected inside the second air cylinder 310, and the top of the second piston rod 309 is fixedly connected to the rack 308.

[0047] like Figure 4As shown, to improve the efficiency of simultaneous operation of the two processing effects, a linkage mechanism for starting the drive assembly is provided at the bottom of the pressure plate 200. The linkage mechanism includes three first piston rods 206 fixedly connected to the bottom of the pressure plate 200. Three first air cylinders 205 adapted to the pressure plate 206 are fixedly connected to the top of the worktable 102 and directly below the three first piston rods 206. An air pipe 208 is fixedly connected inside the worktable 102, and the bottom of the three first air cylinders 205 is connected to a connecting pipe 207 that communicates with the air pipe 208. The cooperation between the first piston rods 206 and the first air cylinders 205 can convert the potential energy generated by the movement of the pressure plate 200 into pneumatic force, thereby driving the gas in the air pipe 208 to expand and provide power for starting the drive assembly. At the same time, the cooperation between the first piston rods 206 and the first air cylinders 205 can guide the up and down movement of the pressure plate 200, so that it can rise and fall stably.

[0048] Among them, such as Figure 8 As shown, an air supply pipe 209 connected to the second air cylinder 310 is connected to the end of the air pipe 208 away from the connecting pipe 207. When the gas in the air pipe 208 expands, it will push the original gas flow in the air pipe 208 to be delivered to the interior of the second air cylinder 310, thereby pushing the rack 308 to move upward, causing it to drive the driven gear 307 to rotate, which in turn drives the drive assembly to open and move multiple abutment blocks 302 in a divergent manner to abut against the inner wall of the connecting hole 105, thereby limiting its movement.

[0049] In summary, by setting up a linkage mechanism to enable the drive component and the transmission component to cooperate with each other, the locomotive headstock body 103 can be synchronously clamped and fixed at both ends, thereby improving the accuracy of the slotting of the locomotive headstock body 103.

[0050] Example 3

[0051] Please see Figure 4 and Figure 5 as well as Figure 6 To further optimize the debris generated during the grooving process of the slotter 101 and improve the cleanliness of the workbench 102 during operation, an empty slot for storing waste debris is constructed on the top of the workbench 102. A support member 404 is fixedly connected to the empty slot, and a fixing ring 401 is fixedly connected to the top of the support member 404. Twelve blades 400 are rotatably connected between the fixing ring 401 and the support member 404. When the twelve blades 400 are set in a horizontal position, they can block the empty slot of the workbench 102, thereby preventing external airflow from entering and causing the internal waste debris to be blown away by the wind.

[0052] Furthermore, to further control the opening and closing of the twelve blades 400, twelve connectors 402 are evenly rotatably connected to the outer surface of the fixed ring 401, and a second crank 403 is rotatably connected between two of the twelve connectors 402 that are close to each other.

[0053] like Figure 6 and Figure 7 As shown, to improve the overall functionality of the device and reduce operational complexity, a third air cylinder 409 is connected to the top of the air pipe 208. A third piston rod 408 is fitted inside the third air cylinder 409, and a straight groove plate 407 is fixedly connected to the top of the third piston rod 408. A connecting plate 405 is fixedly connected to one side of a connector 402, and a limiting rod 406 that is rotatably connected to the straight groove plate 407 is slidably connected to one side of the connecting plate 405. By setting the cooperation between the third piston rod 408 and the third air cylinder 409, the gas in the air pipe 208 can be divided, allowing the airflow generated by the movement of the first piston rod 206 to be reused, thereby achieving multiple uses with one drive and improving its multifunctionality.

[0054] Specifically, when the gas in the air pipe 208 expands, it enters the third air cylinder 409, thereby pushing the third piston rod 408 upward, which in turn pushes the straight groove plate 407 upward, and then pushes the limiting rod 406 upward, causing a change in the angle between a connector 402 and the fixed ring 401. This causes the connector 402 to move in a circular motion along the connection with the fixed ring 401, thereby pulling the connecting plate 405 to move out of position, so that the limiting rod 406 still moves within the straight groove plate 407. At the same time, when a connector 402 rotates, it will be synchronously transmitted through the second crank 403, causing multiple connectors 402 to rotate synchronously, which in turn causes multiple blades 400 to rotate, creating gaps between the multiple blades 400. Then, by adjusting the grooving device 101, the locomotive headstock body 103 can be processed. During this grooving process, the waste generated by grooving will be stored in the empty slot of the worktable 102 through the gaps between the multiple blades 400.

[0055] In summary, the twelve blades 400 can be used to seal or open / close the slots, allowing for flexible use. When slotting the locomotive headstock body 103, the blades 400 can be opened or closed to allow processing waste to enter the slots of the worktable 102. When processing stops, the blades can be closed to prevent the waste from being blown away by the wind.

[0056] Working principle: In use, first, the end of the locomotive leader rod body 103 furthest from the rudder 104 is passed through the positioning hole 303 and placed on top of the extrusion groove 202. Simultaneously, the connecting holes 105 at both ends of the rudder 104 are aligned with the two positioning rods 301, so that the connecting holes 105 fit over the outer surfaces of the two positioning rods 301, thus achieving pre-positioning of the locomotive leader rod body 103. Then, by turning on the drive motor 204, the screw 203 is rotated. At this time, the pressure plate 200 moves downwards, and the bottom of one end of it presses against the top surface of the locomotive leader rod body 103 placed on top of the extrusion groove 202, thereby fixing it in place. Simultaneously, when… When the pressure plate 200 moves downward, it will drive the three first piston rods 206 to move downward into the first air cylinder 205, thereby driving the gas in the first air cylinder 205 to be transported to the inside of the air pipe 208 through the connecting pipe 207. At this time, the gas in the air pipe 208 expands, and a part of the gas is transported to the inside of the second air cylinder 310 through the air delivery pipe 209. Then, as the gas in the second air cylinder 310 gradually increases, it pushes the second piston rod 309 to move upward, which in turn pushes the rack 308 to move upward, thereby driving the driven gear 307 to rotate. At this time, the driven gear 307 rotates and the transmission rod 304 rotates, causing the turntable 305 to rotate, thereby driving the multiple first cranks 306 to rotate with the first piston rod 306. The angles between the multiple contact blocks 302 gradually become perpendicular, causing them to move away from each other and thus move through the through hole of the positioning rod 301 to abut against the inner wall of the connecting hole 105, increasing the frictional force and thus limiting their position. Simultaneously, as the gas in the air pipe 208 increases, another portion of the gas enters the third air cylinder 409, pushing the third piston rod 408 upwards. This pushes the straight groove plate 407 upwards, which in turn pushes the limiting rod 406 upwards, causing a change in the angle between a connecting piece 402 and the fixing ring 401. This causes the connecting piece 402 to move in a circular motion along its connection with the fixing ring 401, thereby pulling the connecting plate 405 to move and misalign. Its limiting rod 406 still moves within the straight slot plate 407. At the same time, when a connecting piece 402 rotates, it will be synchronously driven by the second crank 403 to make multiple connecting pieces 402 rotate synchronously, thereby causing multiple blades 400 to rotate and creating gaps between multiple blades 400. Then, by adjusting the grooving device 101, the locomotive head rod body 103 can be processed. At this time, the grooving is processed, and the waste generated by grooving will be stored in the empty slot of the worktable 102 through the gaps between multiple blades 400. After the processing is completed, the drive motor 204 can be turned on to reverse and release all the limiting functions. At the same time, multiple blades 400 will reset and form a closure.
