Description

Technical Field

[0001] This utility model relates to the field of drilling technology for motor housings, and in particular to a device for drilling wiring holes for mounting housings of new energy vehicle motors. Background Technology

[0002] Currently, new energy vehicles refer to vehicles that use unconventional vehicle fuels as their power source. The motor is the core component of a new energy vehicle, and its performance determines the performance of the vehicle. The motor housing is one of the important components that protect the motor. Generally, in order to facilitate wiring, it is necessary to drill holes in the motor housing. The current motor housing is usually annular inside and square in shape outside with multiple sets of heat dissipation fins. When drilling holes on multiple sides of the motor housing, the drilling device needs to repeatedly disassemble and fix the motor housing, which seriously reduces the drilling efficiency.

[0003] For example, a Chinese patent document discloses a device for drilling holes in a motor housing (publication number: CN220093121U). This patent involves placing the motor housing between two clamping plates, starting a second motor, which drives a bidirectional threaded rod to rotate via a second connecting shaft. The bidirectional threaded rod then drives the two clamping plates to clamp the motor housing. After adjusting the position, the drilling mechanism is started to drill holes in it. Starting a first motor can also cause the motor housing to flip over, improving the drilling efficiency and providing convenience for workers.

[0004] However, because the two clamps block the sides of the motor housing, when flipping and drilling, holes can only be drilled on the top and bottom sides of the motor housing. When drilling holes on the left and right sides of the motor housing, repeated disassembly is still required, which is quite cumbersome. Furthermore, the entire weight of the motor housing is on the connecting rod of motor one, which has poor stability and is prone to failure or even damage to the connecting rod under drilling vibration and pressure. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as poor stability when drilling holes in motor housings and the need for repeated disassembly and assembly when drilling holes on multiple sides, which is cumbersome and reduces drilling efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for drilling wiring holes for mounting housing of motor in new energy vehicles includes a fixed base, and a flipping mechanism is provided above the fixed base;

[0008] The flipping mechanism includes a vertical plate, and a rotating sleeve is rotatably connected to the inner wall of the vertical plate via a bearing. An external gear ring is fixedly sleeved on one end of the rotating sleeve. A servo motor is fixedly installed on one side of the vertical plate. A rotating shaft is fixedly installed on the output shaft of the servo motor via a coupling. A spur gear is fixedly sleeved on one end of the rotating shaft. The tooth surface of the spur gear meshes with the tooth surface of the external gear ring.

[0009] An auxiliary reinforcement mechanism is provided on one side of the upright plate.

[0010] Preferably, a lead screw is rotatably connected to one side of the inner wall of the rotating sleeve via a bearing, and one end of the lead screw passes through to one side of the rotating sleeve and is fixedly connected to a drive handwheel.

[0011] Preferably, the lead screw is externally threaded with threaded blocks arranged in a linear array, and the front and back of the threaded blocks are fixedly connected with symmetrically distributed first supports, the inner wall of the first supports being hinged with a swing rod via a pin.

[0012] Preferably, one end of the swing rod is hinged to a second support via a pin, a sliding block is fixedly connected to the back of the second support, and a guide rod is slidably sleeved on the inner wall of the sliding block.

[0013] Preferably, one end of each of the plurality of guide slide rods is fixedly connected to the inner wall of the rotating sleeve, a drive rod is fixedly connected to the back of the sliding block, and one end of the drive rod extends through to the outside of the rotating sleeve and is fixedly connected to an arc-shaped support block.

[0014] Preferably, the auxiliary reinforcement mechanism includes fixing blocks, with two fixing blocks symmetrically distributed on one side and fixedly connected to the other side of the upright plate, and a servo electric cylinder fixedly installed on the inner wall of the fixing blocks.

[0015] Preferably, one end of the piston rod of the servo electric cylinder is fixedly connected to a clamping plate, and the upper end of the vertical plate is provided with a movable drilling mechanism.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, a servo motor drives a spur gear to mesh with an external gear ring in a flipping mechanism, causing the rotating sleeve and motor housing to flip flexibly. This allows for switching of the drilling surface without repeated disassembly and assembly. Furthermore, the lead screw, drive handwheel, and arc-shaped support block work together to adaptively tighten the motor housing from within, accommodating different specifications of motor housings and ensuring stability. The servo electric cylinder and clamping plate of the auxiliary reinforcement mechanism clamp from the outside, forming a coordinated clamping action with the internal support to disperse drilling vibration and pressure, preventing overload damage to components. This facilitates efficient and precise drilling of motor housings for new energy vehicles, ensuring the processing quality and production efficiency of motor wiring holes.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be provided below with reference to relevant embodiments, and several embodiments of this utility model will be given. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0029] like Figure 1-6 As shown, this utility model provides a technical solution: a hole drilling device for wiring holes in the mounting shell of a new energy vehicle motor, including a fixed base 1. The fixed base 1 is made of cast iron and has good stability and vibration resistance, providing rigid support for the upper flipping mechanism and auxiliary reinforcement mechanism. The bottom of the fixed base has a pre-set mounting hole, which can be fixed to the ground by anchor bolts, further eliminating the risk of displacement during operation.

[0030] The upright plate 2 of the flipping mechanism is connected to the fixed base 1 by bolts, providing an installation reference for the rotating sleeve 21. The inner wall of the rotating sleeve 21 is rotatably connected to the upright plate 2 by bearings, ensuring smooth flipping. The external gear ring 22 fixed at one end meshes with the spur gear 25 to form a reduction transmission pair, so that the power of the servo motor 23 is accurately transmitted, and the rotating sleeve 21 is flipped smoothly.

[0031] The servo motor 23 drives the rotating shaft 24 through a coupling. The spur gear 25 rotates with the rotating shaft 24, which drives the outer gear ring 22 and the rotating sleeve 21 to rotate, realizing the multi-face switching of the motor housing without repeated disassembly and assembly, and adapting to multi-face drilling requirements.

[0032] The lead screw 26 on one side of the inner wall of the rotating sleeve 21 is rotatably connected to the sleeve through a bearing. The drive handwheel 27 at one end facilitates manual adjustment. The threaded block 28 connected to the lead screw 26 moves along the axial direction of the lead screw 26 and pushes the swing rod 210 through the first support 29.

[0033] One end of the swing rod 210 is hinged to the second support 211, which drives the sliding block 212 to slide along the guide rod 213. Finally, the drive rod 214 drives the arc-shaped support block 215 to tighten the motor housing from the inside. This structure can be adapted to motor housings with different inner diameters. The support force is precisely controlled by the screw thread pair to ensure clamping stability.

[0034] The auxiliary reinforcement mechanism has a fixed block 3, a servo electric cylinder 31 installed on the inner wall, and a clamping plate 32 connected to the piston rod end. The surface is covered with a rubber pad. When the motor housing is flipped to the target drilling surface, the servo electric cylinder 31 extends and pushes the clamping plate 32 to clamp the housing from the outside, forming an internal and external coordinated clamping with the internal arc-shaped support block 215. This effectively disperses the vibration and pressure during drilling and avoids overload damage to the transmission components.

[0035] The movable drilling mechanism at the upper end of the vertical plate 2 can adopt an existing CNC drilling machine module. Since it is a fairly mature existing technology, it will not be described in detail. It works in conjunction with the flipping mechanism and the reinforcement mechanism to achieve integrated operation of "clamping-flipping-drilling".

[0036] The working process of this utility model:

[0037] Step 1: Place the motor housing to be drilled over the rotating sleeve 21, rotate the drive handwheel 27, the handwheel drives the lead screw 26 to rotate, the threaded block 28 on the lead screw 26 moves along the lead screw 26, pushes the swing rod 210 through the first support 29, so that the second support 211 drives the sliding block 212 to slide along the guide slide rod 213, and the drive rod 214 drives the arc-shaped support block 215 to open outward from the inside of the motor housing, and adaptively adjusts the support force according to the inner diameter of the housing to complete the initial internal fixation;

[0038] Step 2: Start the servo motor 23. The motor output shaft rotates, which drives the rotating shaft 24 and the spur gear 25 to rotate via the coupling. The spur gear 25 meshes with the external gear ring 22, causing the rotating sleeve 21 and the motor housing to flip, turning the position to be drilled to the top. Then, start the servo electric cylinder 31. The piston rod extends and pushes the clamping plate 32 to approach and clamp the motor housing. It cooperates with the internal arc-shaped support block 215 to form an inner and outer clamp, which enhances the fixation stability and resists the vibration and pressure during drilling.

[0039] Step 3: Start the mobile drilling mechanism. The mobile drilling mechanism is an existing mature technology such as a CNC drilling machine. It runs according to the preset program to perform drilling operations on the upper hole position. When it is necessary to switch the drilling surface, retract the clamping plate 32 of the servo electric cylinder 31, release the external fixation, start the servo motor 23 again, drive the rotating sleeve 21 to rotate, turn the new drilling surface to the top, and repeat the reinforcement and drilling steps until the drilling operation of the multi-sided wiring holes of the motor housing is completed.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
