Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lathe technology for parts processing, and particularly relates to a vertical lathe. Background Technology
[0002] A vertical lathe is a type of lathe with its spindle axis perpendicular to the horizontal plane and the workpiece mounted on a horizontal rotary worktable. It is mainly used for machining workpieces with large diameters and heavy weights, such as gearbox shaft parts. The main motion is completed by rotating the worktable, and the tool post or drill rod is fed along the guide rail. It can complete drilling, boring, reaming and other processes on the complex contours of the workpiece end face, outer circle and inner hole.
[0003] Chinese patent publication number 202223050766.X discloses a vertical lathe, including a base, a lathe body, and a worktable. Roller grooves are formed at both ends of the upper surface of the base, and an adjustment groove is formed between the two roller grooves on the upper surface of the base. A movable column slidably connected to the adjustment groove is set inside the adjustment groove. The upper end of the movable column is fixedly connected to a movable table fixedly connected to the lower end of the lathe body. A bidirectional motor is fixedly connected to one side of the base. An adjustment screw, passing through the base and rotatably connected to the through-hole, is fixedly connected to the output end of the bidirectional motor. The adjustment screw passes through the movable column and is threadedly connected to the through-hole. This allows the vertical tool post to separate from the upper part of the worktable, thus removing any obstructions from the upper part of the worktable. This facilitates the direct hoisting of workpieces to the center of the worktable for processing, eliminating the need for manual workpiece relocation by the operator, which is quite convenient.
[0004] However, existing technologies have the following problems when used: 1. When the drive motor of the vertical lathe provides rotational power to the drill rod, it will continuously generate heat. This heat can be easily transferred directly to the working parts such as the moving frame and the drill rod, making the working parts susceptible to heat and causing problems such as decreased hardness and deformation, thereby reducing machining accuracy.
[0005] 2. During the drilling process, the drill rod generates a lot of heat due to friction with the workpiece. The existing cooling methods are mostly external spraying, and the coolant cannot directly act on the drill rod processing area. The heat exchange is insufficient and cannot quickly remove the heat from the drill rod, which can easily lead to local overheating of the drill rod, further aggravating the wear of the drill rod and affecting the processing quality. Utility Model Content
[0006] The purpose of this utility model is to address the aforementioned technical problems by providing a vertical lathe, comprising: A processing table and a movable frame, wherein the movable frame is slidably disposed above the top of the processing table, a drill rod for drilling is rotatably disposed at the bottom of the movable frame, and a drive motor for driving the drill rod to rotate is disposed at the top of the movable frame; An isolation plate is fixedly connected between the movable frame and the drive motor to isolate the heat generated by the drive motor. The inner cavity of the isolation plate is provided with a first cooling channel for cooling and heat dissipation of the isolation plate. The top of the drill rod is provided with a second cooling channel, and the side wall of the drill rod is provided with a diversion channel that communicates with the second cooling channel. The first cooling channel and the second cooling channel are connected to each other, so as to allow coolant to flow from the first cooling channel into the second cooling channel and allow coolant to be discharged directly from the diversion channel, thereby cooling the drill rod.
[0007] Furthermore, the first cooling channel has a continuous S-shaped distribution.
[0008] Furthermore, a through hole is provided at one bottom end of the isolation plate, the through hole being connected to the flow channel and adapted to the second cooling channel.
[0009] Furthermore, a water tank is fixedly connected to the top of the movable frame, and a pump body is fixedly connected to the side wall of the water tank. The input end of the pump body is connected to the inner cavity of the water tank, and a diversion pipe is fixedly connected to the output end of the pump body. The diversion pipe is connected to the first cooling channel.
[0010] Furthermore, a rotating seat is rotatably connected to the bottom of the movable frame, and the drill rod is fixedly connected to the inner cavity of the rotating seat.
[0011] Furthermore, a second gear is fixedly connected to the outer wall of the rotating seat, and the power output end of the drive motor passes through the top of the movable frame and is fixedly connected to a first gear that meshes with the second gear.
[0012] Furthermore, four threaded seats are fixedly connected to the top of the isolation plate, and the drive motor is fixedly mounted to the threaded seats by bolts.
[0013] Furthermore, a placement frame is rotatably installed at the top center of the processing table, a fixed frame is fixedly connected to one side of the top of the processing table, the movable frame is slidably installed on the side wall of the fixed frame, and a telescopic cylinder is fixedly connected to the top of the fixed frame.
[0014] Furthermore, a mounting plate is fixedly connected to the side wall of the movable frame, and the power output end of the telescopic cylinder passes through the top of the fixed frame and is fixedly connected to the mounting plate.
[0015] Compared with the prior art, the vertical lathe of this utility model has the following advantages: 1. By adding an isolation plate between the movable frame and the drive motor, the heat generated by the drive motor during operation can be blocked from being transferred to key working parts such as the movable frame and drill rod. This prevents problems such as decreased hardness and deformation of working parts such as the drill rod due to heat from the source. At the same time, the first cooling channel designed in the inner cavity of the isolation plate can remove the heat absorbed by the isolation plate itself through the flow of coolant, effectively maintaining the stability of the insulation performance of the isolation plate, further reducing the risk of heat penetration, and ensuring the dimensional accuracy and structural stability of the drill rod during the processing.
[0016] 2. Through the connection design between the first cooling channel and the second cooling channel at the top of the drill rod, combined with the guiding effect of the through hole at the bottom of the isolation plate and the guide channel, the coolant can flow smoothly from the first cooling channel into the second cooling channel, and be directly discharged to the drill rod processing part through the diversion channel on the side wall of the drill rod. This can remove the heat generated by the friction between the drill rod and the workpiece, avoid local overheating of the drill rod, and extend the service life of the drill rod.

[0023] like Figures 1-6 As shown, a vertical lathe includes: The machining table 100 and the movable frame 200 are slidably disposed above the top of the machining table 100. A drill rod 250 for drilling is rotatably disposed at the bottom of the movable frame 200, and a drive motor 222 for driving the drill rod 250 to rotate is disposed at the top of the movable frame 200. An isolation plate 220 is fixedly connected between the movable frame 200 and the drive motor 222 to isolate the heat generated by the drive motor 222. The inner cavity of the isolation plate 220 is provided with a first cooling channel 223, which is used to cool and dissipate heat from the isolation plate 220. The top of the drill rod 250 is provided with a second cooling channel 251, and the side wall of the drill rod 250 is provided with a diversion channel 252 that communicates with the second cooling channel 251. The first cooling channel 223 communicates with the second cooling channel 251 and is used to allow coolant to flow from the first cooling channel 223 into the second cooling channel 251 and allow coolant to be discharged directly from the diversion channel 252 for cooling the drill rod 250.
[0024] As a preferred example of this utility model, the processing table 100 provides basic support for the overall equipment. The movable frame 200 is slidably mounted above the top of the processing table 100, and works in conjunction with the drill rod 250 rotated at its bottom to perform drilling operations. The drive motor 222 fixed to the top of the movable frame 200 provides stable rotational power to the drill rod 250. The isolation plate 220 fixed between the movable frame 200 and the drive motor 222 can prevent the heat generated by the drive motor 222 during operation from being transferred to the movable frame 200 and the drill rod 250, thus avoiding problems such as decreased hardness and deformation of the drill rod 250 due to heat, and also providing isolation. The first cooling channel 223 inside the cavity of plate 220 can remove the heat absorbed by the isolation plate 220 itself through the circulation of coolant, enhance the heat insulation effect, and maintain the stable heat insulation performance of the isolation plate 220. The second cooling channel 251 opened at the top of the drill rod 250 is connected to the diversion channel 252 on the side wall, and the first cooling channel 223 is connected to the second cooling channel 251, so that the coolant can flow smoothly from the first cooling channel 223 into the second cooling channel 251, and then directly act on the processing part of the drill rod 250 through the diversion channel 252, which can remove the heat generated by the drill rod 250 during the drilling process.
[0025] In the example of this application, the first cooling channel 223 has a continuous S-shaped distribution.
[0026] As a preferred example of this utility model, the first cooling channel 223 is designed as a continuous S-shaped structure, which can increase the flow path of the coolant in the first cooling channel 223, increase the contact time and contact area between the coolant and the inner wall of the isolation plate 220, and improve the cooling effect on the isolation plate 220.
[0027] In the example of this application, a through hole 225 is provided at one bottom end of the isolation plate 220. The through hole 225 is connected to the first cooling channel 223 through the flow channel 224, and the through hole 225 is adapted to the second cooling channel 251.
[0028] As a preferred example of this utility model, the through hole 225 at one end of the bottom of the isolation plate 220 is connected to the guide channel 224. The guide channel 224 can guide and converge the coolant flowing out of the first cooling channel 223, so that the coolant can flow to the through hole 225. The through hole 225 is adapted to the second cooling channel 251, so that the coolant can enter the second cooling channel 251 from the through hole 225, and then cool the drill rod 250 through the second cooling channel 251 and the diversion channel 252.
[0029] In the example of this application, a water tank 230 is fixedly connected to the top of the movable frame 200, a pump body 231 is fixedly connected to the side wall of the water tank 230, the input end of the pump body 231 is connected to the inner cavity of the water tank 230, and a diversion pipe 232 is fixedly connected to the output end of the pump body 231, which is connected to the first cooling channel 223.
[0030] As a preferred example of this utility model, the water tank 230 fixed to the top of the movable frame 200 can store coolant. The input end of the pump body 231 fixed to the side wall of the water tank 230 is connected to the inner cavity of the water tank 230, and can draw coolant from the water tank 230. The diversion pipe 232 fixed to the output end of the pump body 231 is connected to the first cooling channel 223, and can deliver the drawn coolant to the first cooling channel 223 to cool the isolation plate 220.
[0031] In the example of this application, the bottom of the movable frame 200 is rotatably connected to the rotating seat 240 via a sealed bearing, the drill rod 250 is fixedly connected to the inner cavity of the rotating seat 240, and the second cooling channel 251 communicates with the through hole 225 through the rotating seat 240.
[0032] As a preferred example of this utility model, the rotating seat 240 rotatably connected to the bottom of the movable frame 200 provides a mounting for the drill rod 250, that is, the drill rod 250 is fixed in the inner cavity of the rotating seat 240. Specifically, the rotating seat 240 can be clamped by screws to fix the drill rod 250. The rotating seat 240 is existing technology and will not be described in detail.
[0033] In the example of this application, a second gear 241 is fixedly connected to the outer wall of the rotating seat 240, and the power output end of the drive motor 222 passes through the top of the movable frame 200 and is fixedly connected to a first gear 226 that meshes with the second gear 241. Specifically, a protective shell for isolation is provided on the outer side of the second gear 241 and the first gear 226.
[0034] As a preferred example of this utility model, the second gear 241 fixed to the outer wall of the rotating seat 240 meshes with the first gear 226 fixed to the power output end of the drive motor 222. When the drive motor 222 is working, its power is transmitted to the second gear 241 through the first gear 226, and then the second gear 241 drives the rotating seat 240 to rotate, thereby realizing the rotation of the drill rod 250. The gear meshing transmission has the characteristics of high transmission efficiency and stable transmission ratio, strong load-bearing capacity, and can adapt to the torque output by the drive motor 222, reducing the equipment failure rate.
[0035] In the example of this application, four threaded seats 221 are fixedly connected to the top of the isolation plate 220, and the drive motor 222 is fixedly installed to the threaded seats 221 by bolts.
[0036] As a preferred example of this utility model, the four threaded seats 221 fixed on the top of the isolation plate 220 are symmetrically distributed, providing support for the drive motor 222. After the drive motor 222 is fixedly connected to the threaded seats 221 by bolts, it can be installed on the isolation plate 220.
[0037] In the example of this application, a placement rack 110 is rotatably provided at the top center of the processing table 100, a fixed frame 120 is fixedly connected to one side of the top of the processing table 100, a movable frame 200 is slidably disposed on the side wall of the fixed frame 120, and a telescopic cylinder 130 is fixedly connected to the top of the fixed frame 120.
[0038] As a preferred example of this utility model, the placement rack 110, which is rotatably mounted at the top center of the processing table 100, is used to place the workpiece to be processed. The operator can adjust the processing angle and position of the workpiece by rotating the placement rack 110. The fixed frame 120, which is fixed on one side of the top of the processing table 100, provides a stable sliding track for the movable frame 200. The movable frame 200 is not prone to deviation when sliding along the side wall of the fixed frame 120. The telescopic cylinder 130, which is fixed at the top of the fixed frame 120, can provide power for the up and down movement of the movable frame 200. Through the telescopic movement of the telescopic cylinder 130, the height of the movable frame 200 and the drill rod 250 can be adjusted, so that the equipment can be adapted to the processing of workpieces of various specifications, thereby improving the applicability of the equipment.
[0039] In the example of this application, the side wall of the movable frame 200 is fixedly connected to the mounting plate 210, and the power output end of the telescopic cylinder 130 passes through the top of the fixed frame 120 and is fixedly connected to the mounting plate 210.
[0040] As a preferred example of this utility model, after the power output end of the telescopic cylinder 130 passes through the top of the fixed frame 120 and is fixedly connected to the mounting plate 210, the telescopic cylinder 130 can directly drive the movable frame 200 to rise and fall, reducing the impact of the rotational force generated by the drive motor 222 on the telescopic cylinder 130.
[0041] In use, the vertical lathe is supported by a machining table 100. A rotating mounting bracket 110 at the top center of the machining table 100 allows adjustment of the workpiece's position and angle. A fixed bracket 120 on one side of the top of the machining table 100 provides a stable sliding track for the movable frame 200. A telescopic cylinder 130 fixed at the top of the movable frame 200, through a fixed connection with a mounting plate 210 on the side wall of the movable frame 200, drives the movable frame 200 to move up and down along the fixed bracket 120. A drive motor 222 is fixed to the top of the movable frame 200 via four symmetrically distributed threaded seats 221 and bolts. The power output of the drive motor 222 passes through the movable frame 200 and is transmitted to the rotary seat 240 via the meshing of a first gear 226 and a second gear 241 on the outer side wall of the rotary seat 240, which is rotatably connected to the bottom of the movable frame 200. This transmission drives the internal cavity of the rotary seat 240. The fixed drill rod 250 rotates, and at the same time, the isolation plate 220 between the movable frame 200 and the drive motor 222 can block the heat generated by the drive motor 222, preventing the heat from affecting the performance of the movable frame 200 and the drill rod 250. The continuous S-shaped first cooling channel 223 inside the isolation plate 220 can extend the flow path of the coolant and increase the heat exchange area. The water tank 230 at the top of the movable frame 200 stores the coolant, which is drawn by the pump body 231 and transported to the first cooling channel 223 through the diversion pipe 232. The coolant then flows into the second cooling channel 251 through the through hole 225 of the second cooling channel 251 at the top of the drill rod 250, which is connected to the guide channel 224 at the bottom of the isolation plate 220 and adapted to the second cooling channel 251 at the top of the drill rod 250. Finally, it is discharged from the diversion channel 252 on the side wall of the drill rod 250, taking away the heat generated by the isolation plate 220 and the drill rod 250, thus completing the use.
[0042] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
