Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically to a device for drilling holes in a motor housing to prevent dents. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to generate driving torque. The motor is protected by a housing. The housing protects the motor from dust and water entering the motor and damaging its internal structure. It also connects to external mechanical structures. During the production of the motor housing, holes need to be drilled.

[0003] A search revealed that the Chinese patent "A Drilling Device for Motor Housing Production" (authorization announcement number CN222448355U) utilizes the operation of a first cylinder to move two transverse moving plates, causing a transverse rotating roller, a transverse driven roller, and a vertical connecting plate to move towards the motor housing body and clamp the motor housing body. The clamping assembly can clamp the motor housing body and allow it to rotate, adjusting the drilling angle of the motor housing body. Furthermore, the support block conforms to the interior of the motor housing body, providing internal support at the drilling points and effectively preventing surface dents.

[0004] Although the above application can clamp the motor housing, the lateral driven roller contacts the surface of the motor housing during clamping. Since vibration will be generated during the drilling process, the motor housing is prone to rotation during the drilling process, which will lead to drilling errors and affect the drilling effect.

[0005] Based on this, the present invention designs a motor housing drilling device to prevent the housing from denting in order to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a device for drilling holes in motor housing to prevent the housing from being dented.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A device for drilling holes in a motor housing to prevent dents includes a worktable, a movable plate slidably connected to the upper inner side of the worktable, a movable block slidably connected to the inner wall of the movable plate, a hydraulic cylinder fixedly connected to the inner wall of the movable block, and a drilling mechanism fixedly connected to the bottom end of the hydraulic cylinder.

[0009] It also includes a fixing mechanism, which includes a fixing rod and a first electric push rod fixedly connected to the top of the workbench. A circular plate is fixedly connected to the telescopic end of the first electric push rod. A circular rod is fixedly connected to one side of the fixing rod. A limit plate is fixedly connected to the end of the circular rod away from the fixing rod. A second electric push rod is fixedly connected to both the top and bottom ends of the fixing rod. A connecting plate is fixedly connected to the telescopic end of the second electric push rod. A fixing plate is fixedly connected to one end of the connecting plate.

[0010] Furthermore, the fixing mechanism also includes two support plates slidably connected inside the upper fixing plate. Limiting blocks are slidably connected to opposite sides of the two support plates, and a support block is fixedly connected between opposite sides of the two limiting blocks. A round hole is opened at the top of the support block. An mounting plate is fixedly connected to the lower end of the surface of the hydraulic cylinder. A connecting rod is slidably connected to the inner wall of the mounting plate, and one end of the connecting rod is fixedly connected to the bottom end of the support block.

[0011] Furthermore, the limiting plate and the circular plate are both fixedly connected to contact pads at their opposite ends, and the contact pads are rubber components.

[0012] Furthermore, the vertical cross-section of the limiting block is "T" shaped, and the opposite sides of the two support plates are provided with sliding grooves that match the limiting block.

[0013] Furthermore, the surface of the fixing plate is bent into an arc shape, and a rubber pad is fixedly connected to the outer surface of the fixing plate.

[0014] Furthermore, the center of the limiting plate and the center of the circular plate are on the same axis, and the diameter of the limiting plate is smaller than the diameter of the circular plate.

[0015] Furthermore, the surface of the fixed plate described above is provided with a through groove, and the support plate is disposed in the through groove.

[0016] Furthermore, the surfaces of the two support plates are curved into an arc shape, and the two support plates are symmetrical about the center of the support block.

[0017] Beneficial effects

[0018] 1. The above-mentioned fixing mechanism, when fixing the motor housing by drilling holes, uses a limiting plate to press against the motor housing from the inside, and interacts with the circular plate to fix the motor housing. During the movement and fixing of the circular plate, the limiting plate limits the movement distance of the circular plate, preventing the circular plate from continuing to move after fixing the motor housing. This avoids excessive compression of the motor housing during the fixing process, which could cause deformation of the motor housing. This ensures the fixing effect while also protecting the motor housing. Furthermore, the two fixing plates pressing against the motor housing from the inside helps to support the motor housing when drilling holes, ensuring the stability of the motor housing during drilling, avoiding drilling errors, and improving the drilling effect.

[0019] 2. During drilling, the support block provides support from inside the motor housing to the drilling position, which increases the strength of the motor housing around the drilling position and prevents dents from occurring. At the same time, the support block moves synchronously with the drilling mechanism, which drives the two support plates to move synchronously, which helps the two support plates to maintain the support effect around the drilling position at all times.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-5 A device for drilling holes in a motor housing to prevent dents includes a worktable 100, a movable plate 200 slidably connected to the upper inner side of the worktable 100, a movable block 300 slidably connected to the inner wall of the movable plate 200, a hydraulic cylinder 400 fixedly connected to the inner wall of the movable block 300, and a drilling mechanism 500 fixedly connected to the bottom end of the hydraulic cylinder 400.

[0031] It also includes a fixing mechanism 600, which includes a fixing rod 610 fixedly connected to the top of the workbench 100 and a first electric push rod 620. A circular plate 621 is fixedly connected to the telescopic end of the first electric push rod 620. A circular rod 611 is fixedly connected to one side of the fixing rod 610. A limit plate 612 is fixedly connected to the end of the circular rod 611 away from the fixing rod 610. A second electric push rod 630 is fixedly connected to both the top and bottom ends of the fixing rod 610. A connecting plate 640 is fixedly connected to the telescopic end of the second electric push rod 630. A fixing plate 650 is fixedly connected to one end of the connecting plate 640.

[0032] It should be noted that electric slide rails are installed on one side of the top of the workbench 100 and the top of the movable plate 200. The electric slide rail includes a fixed frame, a drive motor, a lead screw, and a slider. The lead screw is rotatably connected to the inner wall of the fixed frame, and the inner wall of the slider is threadedly connected to the surface of the lead screw. The output shaft of the drive motor is fixedly connected to one end of the lead screw. When the drive motor is started by control, the output shaft of the drive motor will drive the lead screw to rotate, thereby driving the slider to move. One side of the movable plate 200 is connected to the slider in the electric slide rail installed on the workbench 100. The electric slide rail can drive the movable plate 200 to drive the hydraulic cylinder 400 and the drilling mechanism 500 to move longitudinally. The movable block 300 is connected to the slider in the electric slide rail installed on the movable plate 200. The electric slide rail at the top of the movable plate 200 can drive the hydraulic cylinder 400 and the drilling mechanism 500 to move laterally.

[0033] The drilling mechanism 500 includes a mounting frame that is fixedly connected to the telescopic end of the hydraulic cylinder 400. A motor is fixedly connected inside the mounting frame. The output shaft of the motor passes through the mounting frame and is fixedly connected to a drill bit. When drilling a hole in the motor housing, the hydraulic cylinder 400 is started by the controller to push the drilling mechanism 500 downward. At the same time, the motor is started by the controller to drive the drill bit to rotate, thus performing the drilling operation.

[0034] In this embodiment of the invention, in the initial state, the distance between the opposite ends of the limiting plate 612 and the circular plate 621, and the overall length of the circular rod 611, are both greater than the length of the motor housing to be drilled. Furthermore, the lower end of the surface of the limiting plate 612 does not contact the top of the worktable 100. When drilling the motor housing, the motor housing is placed between the opposite ends of the limiting plate 612 and the circular plate 621. After placement, the motor housing is moved horizontally to allow the limiting plate 612 to enter the interior of the motor housing, thus pressing the motor housing against the limiting plate 612. At this time, the controller activates the first electric push rod 620 to push the circular plate 621 to move. 21. When one end of the motor housing is pressed against the limit plate 612 during the movement, the circular plate 621 cannot continue to move under the action of the limit plate 612, and cooperates with the limit plate 612 to fix the motor housing. After this operation is completed, the controller starts the two second electric push rods 630. When the second electric push rods 630 are running, they will push the connecting plate 640 to move the fixing plate 650, so that the two fixing plates 650 press against the motor housing from the inside of the motor housing and fix it. After fixing, the position of the drilling mechanism 500 is adjusted and the hydraulic cylinder 400 is driven to push the drilling mechanism 500 downward to drill holes in the motor housing.

[0035] In this embodiment of the utility model, when drilling and fixing the motor housing, the limiting plate 612 limits the moving distance of the circular plate 621, preventing the circular plate 621 from continuing to move after fixing the motor housing. This avoids excessive compression of the motor housing during the fixing process, which could cause deformation of the motor housing. Furthermore, the two fixing plates 650 press against the motor housing from the inside, which helps to support the motor housing during drilling, ensuring stability during drilling, avoiding drilling errors, and improving the drilling effect.

[0036] In some embodiments, such as Figure 2-5 As shown, in a preferred embodiment of the present invention, the fixing mechanism 600 further includes two support plates 660 slidably connected inside the upper fixing plate 650. Limiting blocks 661 are slidably connected to opposite sides of the two support plates 660. A support block 662 is fixedly connected between opposite sides of the two limiting blocks 661. A round hole is opened at the top of the support block 662. An mounting plate 670 is fixedly connected to the lower end of the surface of the hydraulic cylinder 400. A connecting rod 671 is slidably connected to the inner wall of the mounting plate 670. One end of the connecting rod 671 is fixedly connected to the bottom end of the support block 662.

[0037] In this embodiment of the utility model, when the device is in the initial state, the center of the circular hole and the center of the drill bit in the drilling mechanism 500 are on the same axis, and the diameter of the circular hole is larger than the diameter of the drill bit. When the top of the upper fixing plate 650 is pressed against the inner wall of the motor housing, the tops of the support plate 660 and the support block 662 are pressed against the inner wall of the motor housing. When the drilling mechanism 500 drills, the support block 662 is located below the drilling position and presses against the motor housing.

[0038] When the position of the drilling mechanism 500 is adjusted, the support block 662 will move synchronously under the action of the mounting plate 670 and the connecting rod 671. When the hydraulic cylinder 400 drives the drilling mechanism 500 to move laterally, the support block 662 will move laterally synchronously through the mounting plate 670 and the connecting rod 671, and the limiting block 661 will slide on the inner wall of the support plate 660. When the hydraulic cylinder 400 drives the drilling mechanism 500 to move longitudinally, the support block 662 will move longitudinally synchronously through the mounting plate 670 and the connecting rod 671. At this time, the support block 662 will drive the two support plates 660 to move longitudinally synchronously through the two limiting blocks 661.

[0039] In this embodiment of the utility model, the support block 662 moves synchronously with the drilling mechanism 500, while simultaneously driving the two support plates 660 to move synchronously, which helps the two support plates 660 to always maintain the support effect on the area around the drilling position.

[0040] In some embodiments, such as Figure 2-3As shown, in a preferred embodiment of the present invention, the opposite ends of the limiting plate 612 and the circular plate 621 are fixedly connected with contact pads, which are rubber components.

[0041] In this embodiment of the utility model, when the limiting plate 612 and the circular plate 621 fix the motor housing, the surface of the contact pad contacts the surface of the motor housing, which is beneficial to protect the motor housing while fixing it, and at the same time improves the friction between the limiting plate 612 and the circular plate 621 and the motor housing.

[0042] In some embodiments, such as Figure 5 As shown, in a preferred embodiment of the present invention, the vertical cross-section of the limiting block 661 is "T" shaped, and the opposite sides of the two support plates 660 are provided with sliding grooves that match the limiting block 661.

[0043] In this embodiment of the utility model, when the support block 662 moves longitudinally, the "T"-shaped slide cannot fall out of the slide groove and drives the support plate 660 to move synchronously, thus ensuring the stability of the support plate 660 moving synchronously when the support block 662 moves longitudinally.

[0044] In some embodiments, such as Figure 3-4 As shown, in a preferred embodiment of the present invention, the surface of the fixing plate 650 is bent into an arc shape, and a rubber pad 680 is fixedly connected to the outer surface of the fixing plate 650.

[0045] In this embodiment of the utility model, the arc-shaped fixing plate 650 is conducive to better contact with the inner wall of the motor housing, and when the fixing plate 650 is pressed against the inner wall of the motor housing, the surface of the rubber pad 680 is in contact with the inner wall of the motor housing, which is beneficial to protect the motor housing while the fixing plate 650 is pressed against the inner wall of the motor housing, and at the same time improves the friction force when the fixing plate 650 is pressed against the motor housing.

[0046] In some embodiments, such as Figure 2 As shown, in a preferred embodiment of the present invention, the center of the limiting plate 612 and the center of the circular plate 621 are on the same axis, and the diameter of the limiting plate 612 is smaller than the diameter of the circular plate 621.

[0047] In this embodiment of the utility model, the fixing effect of the limiting plate 612 and the circular plate 621 is guaranteed.

[0048] In some embodiments, such as Figure 4 As shown, in a preferred embodiment of the present invention, the surface of the upper fixing plate 650 is provided with a through groove, and the support plate 660 is disposed in the through groove.

[0049] In this embodiment of the utility model, an arc-shaped groove is provided on one side of the inner wall of the support plate 660, and the surface of one end of the support plate 660 is slidably connected to the inner wall of the arc-shaped groove. When the support block 662 drives the support plate 660 to move longitudinally, the arc-shaped groove limits the movement of the support plate 660.

[0050] In some embodiments, such as Figure 5 As shown, in a preferred embodiment of the present invention, the surfaces of the two support plates 660 are curved into an arc shape, and the two support plates 660 are symmetrical about the center of the support block 662.

[0051] In this embodiment of the utility model, the arc-shaped support plate 660 makes better contact with the inner wall of the motor housing, and the two support plates 660 are symmetrical, which is beneficial to make the two support plates 660 provide the same support force to the motor housing on both sides of the support block 662.

[0052] It should be noted that the hydraulic cylinders, electric actuators, and motors mentioned above are all components with relatively mature existing technologies. Specific models can be selected according to actual needs. At the same time, the hydraulic cylinders, electric actuators, and motors can be powered by built-in power supplies or by mains power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

[0053] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
