Description

Technical Field

[0001] This utility model relates to the field of motor end cover processing technology, and more specifically to a motor end cover drilling device. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. An end cover is a back cover installed behind the casing of an electric motor or similar device. Its manufacturing process is complex, and drilling holes is one of the steps involved.

[0003] A search revealed a Chinese patent with publication number CN220592335U, which discloses a device for drilling holes in motor end caps. This device can securely clamp and fix end caps of different models of motors and has good applicability. However, when the device clamps the workpiece with clamping parts, the clamping parts only clamp the two sides of the workpiece. When drilling, the workpiece is easy to fall off the clamping parts and needs to be re-fixed, which affects the drilling efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a motor end cover punching device to solve the problems existing in the background art.

A sliding rod is fixedly connected between the two first fixing plates in each set, and the two sliding rods pass through the two ends of the two slides and are slidably connected to them.

[0008] As a further embodiment of this utility model, the upper surface of the workbench is provided with a clearance opening, and the clearance opening is located directly below the drilling assembly.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1-4This utility model provides a device for drilling holes in a motor end cap, including a workbench 1. Two symmetrical second fixing plates 10 are bolted to the upper surface of the workbench 1. A bidirectional lead screw 18 is rotatably connected between the two second fixing plates 10 via bearings. Two symmetrical fixing blocks 22 are threaded onto the bidirectional lead screw 18. A slide 11 is bolted to each of the two fixing blocks 22. Arc-shaped clamping plates 21 are bolted to the opposing sides of the two slides 11. Stepped grooves 23 are formed on the opposing sides of the two arc-shaped clamping plates 21. A second motor end cap is bolted to one side of one of the second fixing plates 10. The output shaft of the second motor 20 is fixed to one end of the bidirectional lead screw 18. The upper surface of the worktable 1 is fixedly connected with multiple symmetrical support rods 2 by bolts. The top of the multiple support rods 2 is fixedly connected to a top plate 3 by bolts. The top plate 3 is provided with a drilling assembly. Through the provided arc-shaped clamping plate 21 and the stepped groove 23 opened on it, the bottom of the end cover is lifted while clamping it. During the processing, the end cover will not fall off due to the lack of support at the bottom when the downward force is applied to the end cover during drilling, thus saving time and increasing the working efficiency of the device.

[0023] In this invention, the drilling assembly is an electric push rod 4, which is bolted to the upper surface of the top plate 3. One end of the electric push rod 4 passes through the lower surface of the top plate 3 and is bolted to a fixing frame 5. A first motor 6 is bolted to the inner bottom wall of the fixing frame 5. One end of the output shaft of the first motor 6 passes through the outer bottom wall of the fixing frame 5 and is keyed to a first gear 12. A plurality of rotating shafts 13 arranged in a circular array are rotatably connected to the lower surface of the fixing frame 5. A second gear 14 is bolted to the outer circumference of each of the multiple rotating shafts 13, and each of the multiple second gears 14 meshes with the first gear 12. Drill bits 15 are detachably connected to the bottom ends of each of the multiple rotating shafts 13. With multiple drill bits 15, multiple holes can be machined simultaneously when drilling the motor end cover, avoiding the deviation that occurs when drilling one hole at a time, and further increasing the drilling efficiency of the device for the motor end cover. The upper surface of the worktable 1 is fixedly connected with two symmetrical sets of first fixing plates 9 by bolts. Each set consists of two symmetrical plates, and the two sets are located on both sides of the arc-shaped clamping plate 21. The two first fixing plates 9 in each set are fixedly connected with slide rods 17 by bolts. The two slide rods 17 pass through the two ends of the two slides 11 and are slidably connected to them. The slide rods 17 can guide the slides 11 as they move left and right, increasing the stability of the slides 11. Qualitatively, this increases the stability of the arc-shaped clamping plate 21 in clamping the motor end cover. A clearance opening 19 is provided on the upper surface of the worktable 1, located directly below the drilling assembly. A collection box 8 is slidably connected inside the worktable 1, located directly below the clearance opening 19, and its width is greater than the diameter of the clearance opening 19. The clearance opening 19 and collection box 8 collect debris generated during drilling, preventing it from falling onto the worktable 1 and requiring manual cleaning, thus saving time and labor costs. Two symmetrical placement boxes 7 are slidably connected inside the worktable 1, located on either side of the collection box 8. These placement boxes 7 can hold some... The tools are placed in the storage box 7 for easy access. The top outer wall of the fixed frame 5 is bolted with two guide rods 16. The two guide rods 16 are located on both sides of the electric push rod 4, and both guide rods 16 pass through the top of the top plate 3 and are slidably connected to it. The top of each guide rod 16 is bolted with a limit block. The guide rods 16 can guide the drilling assembly during its up and down movement to prevent drilling deviation and increase drilling accuracy. The bottom of the worktable 1 is bolted with multiple support frames. The bottom of each support frame has multiple mounting holes. The support frames can be used to fix the device and increase its stability.

[0024] The use of this utility model involves the following steps:

[0025] S1: When the motor end cover needs to be processed, the second motor 20 is started first to drive the bidirectional lead screw 18 to rotate. When the bidirectional lead screw 18 rotates, it will drive the two fixed blocks 22 on it to move towards each other. Then, the two slides 11 move towards each other along the slide rod 17, which will bring the two arc-shaped clamps 21 closer to each other. During the movement, the motor end cover is placed on the stepped grooves 23 on the two arc-shaped clamps 21. After the movement continues, the inner walls on both sides of the arc-shaped clamps 21 are in close contact with the outer circumference of the motor end cover, and the motor end cover can be fixed.

[0026] S2: Then start the first motor 6 to drive the first gear 12 to rotate. During the rotation of the first gear 12, it drives the multiple second gears 14 meshing with it to rotate, which in turn drives the rotating shaft 13 on it. The rotating shaft 13 rotates to make the drill bit 15 rotate. Then start the electric push rod 4 to extend and drive the fixed frame 5 to move downward. When the drill bit 15 contacts the motor end cover, the drilling operation can be performed on the motor end cover.

[0027] S3: During the drilling process, the debris generated falls into the collection box 8 through the clearance opening 19. The debris is collected and processed to prevent it from falling onto the workbench 1 and requiring manual cleaning, thus saving time and labor costs.

[0028] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship.
