Description

Technical Field

[0001] This utility model relates to the field of drilling, and more specifically to a device for machining mounting holes in an oil-immersed motor end housing. Background Technology

[0002] The core of an oil-immersed motor is the enclosure of the motor windings and rotor with insulating cooling oil, primarily used in applications requiring efficient heat dissipation and sealed protection. To improve the motor's heat dissipation efficiency, its end housing is typically a perforated structure, as shown in the attached image. Figure 8 As shown, the mounting end of this type of hollow structure end shell protrudes outward, and its mounting hole needs to be machined at the protruding edge. Due to the limitations of its main structure, when machining the mounting hole, it is necessary to drill the mounting hole facing the main structure. This makes it difficult to fix the hollow structure end shell in the center, which affects the drilling process. Utility Model Content

[0003] This utility model provides a device for machining mounting holes in the end housing of an oil-immersed motor, which can fix the end housing in the center and facilitate the machining of mounting holes.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: A device for machining mounting holes in the end housing of an oil-immersed motor includes a support frame, a rotary table, a clamping mechanism, and a drilling mechanism. The rotary table rotates on the upper end of the support frame to support the end housing. The clamping mechanism slides and lifts on the support frame to cooperate with the rotary table to clamp and fix the end housing in the center. The drilling mechanism slides and lifts on the upper end of the clamping mechanism to drill mounting holes at the edge of the end housing.

[0005] The rotary table includes a rotating disk that rotates at the middle position of the upper end of the support frame. A platform plate is coaxially fixed to the upper end of the rotating disk, and a centering mechanism is installed at the center of the platform plate.

[0006] The centering mechanism includes a sliding plate that limits lifting and sliding between the rotating disk and the platform plate. A cone block is fixed in the middle of the sliding plate, and the cone block passes through the center of the platform plate. A spring is provided between the sliding plate and the rotating disk.

[0007] The rotary table also includes a drive shaft and a worm gear that rotate on a support frame. The upper end of the drive shaft is meshed with the rotary disk for transmission, and the lower end of the drive shaft is meshed with the worm gear for transmission.

[0008] The clamping mechanism includes a slide bar frame I that slides through the support frame, a clamping plate fixed at the upper end of the slide bar frame I, and an electric telescopic rod I installed between the lower end of the slide bar frame I and the support frame.

[0009] The drilling mechanism includes a slide bar frame II vertically fixed to the upper end of the pressure plate, and a mounting frame that slides and lifts on the slide bar frame II. A drill bit holder is installed inside the mounting frame, and a drill bit is installed at the lower end of the drill bit holder. An electric telescopic rod II is installed between the upper end of the slide bar frame II and the mounting frame.

[0010] An adjusting screw is rotatable within the mounting frame, and the adjusting screw is threadedly connected to the drill bit seat.

[0011] The platform plate is rotatably connected by a bidirectional screw, and clamping blocks are symmetrically threaded onto the bidirectional screw. The upper ends of the two clamping blocks both penetrate the platform plate.

[0012] The upper end of the clamping block is cylindrical.

[0013] The lower end face of the clamping plate is provided with a rubber layer.

[0014] The beneficial effects of this utility model are: During processing, the end housing is fitted onto the cone head of the cone block to ensure that the end housing is initially centered. Then, the clamping plate presses down on the mounting end face of the end housing, causing the end housing to be vertically pressed against the cone head of the cone block, thereby centered the end housing vertically until the clamping plate presses the end housing onto the platform plate, thus fixing the end housing in a centered position. The drilling mechanism then moves up and down to complete the processing of the mounting hole. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The following is combined with Figure 1-7 A detailed description is provided of a device for machining mounting holes in the end housing of an oil-immersed motor. A device for machining mounting holes in the end housing of an oil-immersed motor includes a support frame 1, a rotary table, a clamping mechanism, and a drilling mechanism. The rotary table rotates on the upper end of the support frame 1 to support the end housing. The clamping mechanism slides and lifts on the support frame 1 to cooperate with the rotary table to clamp and fix the end housing in the center. The drilling mechanism slides and lifts on the upper end of the clamping mechanism to drill mounting holes at the edge of the end housing.

[0019] The support frame 1 is used to support the entire device, the rotary table is used to place the end housing, and the clamping mechanism is used to clamp the end housing onto the rotary table. At the same time, through the cooperation of the rotary table and the clamping mechanism, the end housing can be centered and clamped and fixed. At this time, the mounting end face of the end housing is horizontally located above. Thus, the drilling mechanism is controlled to slide up and down the clamping mechanism to drill the mounting hole at the edge of the end housing.

[0020] Further: The rotary table includes a rotating disk 4 that rotates at the middle position of the upper end of the support frame 1. A platform plate 5 is coaxially fixed to the upper end of the rotating disk 4, and a centering mechanism is installed at the center of the platform plate 5.

[0021] The centering mechanism includes a sliding plate 8 that is limited, lifted, and slidable between the rotating disk 4 and the platform plate 5. A cone block 6 is fixed in the middle of the sliding plate 8, and the cone block 6 passes through the center of the platform plate 5. A spring 9 is provided between the sliding plate 8 and the rotating disk 4.

[0022] Platform plate 5 is used to support the end housing. When placing the end housing, the center hole of the main structure of the end housing is fitted onto the tip of the cone block 6. Supported by the tip of the cone block 6, the end housing is in an inclined state. The clamping mechanism is controlled to descend and press against the mounting surface of the end housing, thereby causing the end housing to automatically turn upright and be guided by the tip of the cone block 6. The end housing is automatically centered and aligned. As the clamping mechanism presses the end housing down, the end housing will press against the cone block 6 as it descends, causing the cone block 6 to squeeze the spring 9 until the end face of the main structure of the end housing presses against the platform plate 5. This forms a cooperation between the rotary table and the clamping mechanism, which clamps and fixes the end housing in the center. At this time, the mounting end face of the end housing is horizontally set at the top of the end housing, which facilitates the drilling mechanism to descend and complete the processing.

[0023] Further: The rotary table also includes a drive shaft 2 and a worm gear 3 that rotate on the support frame 1. The upper end of the drive shaft 2 is engaged with the rotating disk 4 for transmission, and the lower end of the drive shaft 2 is engaged with the worm gear 3 for transmission.

[0024] After machining one mounting hole, the clamping mechanism is raised to relax the end housing between the rotary table and the clamping mechanism. The worm 3 is rotated, and the worm gear on the transmission shaft 2 is driven to rotate through the meshing of the worm 3 and the worm wheel on the transmission shaft 2. This drives the transmission shaft 2 to rotate, which in turn drives the rotating disk 4 to rotate the platform plate 5. This, in turn, drives the end housing to rotate, thus switching to the machining position of another mounting hole.

[0025] Further: The clamping mechanism includes a slide bar frame I11 that slides through the support frame 1. A clamping plate 12 is fixed at the upper end of the slide bar frame I11, and an electric telescopic rod I14 is installed between the lower end of the slide bar frame I11 and the support frame 1.

[0026] By activating the extension of the electric telescopic rod I14, the slide rod I11 can be controlled to descend on the support frame 1, which in turn drives the pressure plate 12 to descend, thereby causing the lower end face of the pressure plate 12 to press against the mounting surface of the end housing, thus clamping and fixing the end housing.

[0027] Further: The drilling mechanism includes a slide bar frame II13 vertically fixed to the upper end of the pressure plate 12, and a mounting frame 16 that slides and lifts on the slide bar frame II13. A drill bit seat 17 is installed inside the mounting frame 16, and a drill bit 18 is installed at the lower end of the drill bit seat 17. An electric telescopic rod II15 is installed between the upper end of the slide bar frame II13 and the mounting frame 16.

[0028] The drill bit holder 17 is equipped with a drill bit motor, which drives the drill bit 18 to rotate. When the electric telescopic rod II 15 is activated to extend, it can push the mounting frame 16 down on the slide rod frame II 13, thereby allowing the drill bit 18 to descend and complete the drilling of the mounting hole.

[0029] Further: An adjusting screw 19 is rotatably mounted inside the mounting frame 16, and the adjusting screw 19 is threadedly connected to the drill bit holder 17.

[0030] Rotating the adjusting screw 19 allows the drill bit seat 17 to slide within the mounting frame 16 by engaging with the screw 19 threadedly. This changes the distance between the drill bit 18 and the central axis of the end housing, enabling the device to accommodate the machining of mounting holes for end housings of different radii.

[0031] Further: The platform plate 5 is rotatably connected by a bidirectional screw 10, and clamping blocks 7 are symmetrically threaded onto the bidirectional screw 10. The upper ends of the two clamping blocks 7 both penetrate the platform plate 5.

[0032] Rotating the bidirectional screw 10 allows the two clamping blocks 7 to move closer or further apart through the threaded engagement between the bidirectional screw 10 and the clamping block 7. This enables the end housing to be clamped again by the two clamping blocks 7 after the rotary table and the clamping mechanism have clamped it, further ensuring the fixation of the end housing.

[0033] Further: The upper end of the clamping block 7 is cylindrical, which makes it easier to clamp the end housing.

[0034] Further: By providing a rubber layer on the lower end face of the clamping plate 12, the rubber layer can contact the mounting end face of the end housing, thereby protecting the mounting end face of the end housing.

[0035] Of course, the above description is not a limitation of this instruction manual, and this utility model is not limited to the examples mentioned above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model are also within the protection scope of this utility model.
