Description

Technical Field

[0001] The utility model relates to the technical field of drilling devices, in particular to a drilling device for machining a motor stator and rotor. Background Art

[0002] A motor refers to an electromagnetic device that realizes electrical energy conversion or transmission based on the law of electromagnetic induction. Its main function is to generate driving torque. A common and important part of the motor is the stator and rotor punchings. The stator and rotor punchings need to be drilled during processing. At the same time, in order to improve the drilling efficiency, multiple stator and rotor punchings are usually stacked vertically together, and then the drilling operation of the multiple stator and rotor punchings is carried out together. China has authorized a utility model patent (Announcement No.: CN220838046U) to disclose a stator and rotor processing device for a flat wire motor for new energy vehicles. It overcomes the problem that one end of the drilling hole of the existing multiple stator and rotor punchings is affected by the pressure of the hole-opening drill bit, and the other side of the multiple stator and rotor punchings is bent, thereby causing the multiple stator and rotor punchings to be skewed due to the bending force, resulting in changes in the upper and lower drilling positions of the multiple stator and rotor punchings, so that the drilling points of the multiple stator and rotor punchings are not on the same vertical line, affecting the drilling accuracy of the multiple stator and rotor punchings.

[0003] However, the above device still has some shortcomings when used: specifically, since metal debris is generated during the drilling operation, these debris fall directly on the drilling device due to gravity and are scattered, making it difficult to clean them quickly and effectively, which brings inconvenience to the cleaning work of the staff. Therefore, in response to the above situation, a drilling device for motor stator and rotor processing is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a drilling device for processing motor stators and rotors. Through the structural design of the waste collection box, support rods, guide plates, reserved holes and frame, the debris generated during the drilling process can be guided to a preset collection area, solving the problem that metal debris is difficult to clean in the prior art.

[0005] The utility model is realized through the following technical solutions:

[0006] The utility model relates to a drilling device for processing motor stators and rotors, which comprises a fixing frame. A supporting plate is arranged on the fixing frame. A supporting plate is installed on the supporting plate in a liftable manner. An assembly groove is formed in the supporting plate. A waste collecting box is slidably fitted on the assembly groove. A limiting member is arranged on the supporting plate. The limiting member comprises a column and a limiting block. The column is fixed on the supporting plate. The limiting block has a round hole, and the round hole is in clearance fit with the column. The limiting block contacts the surface of the waste collecting box. A guiding component is arranged on the top of the supporting plate. The number of the guiding components is two. The guiding component comprises a supporting rod. There are four supporting rods in total. A guiding plate is obliquely arranged on the four supporting rods. The guiding plate has reserved holes. The number of the reserved holes is two. A frame is arranged on the top of the guiding plate. The shape of the frame is "U" shaped.

[0007] Furthermore, a cylinder is arranged on the top of the supporting plate. There is a pair of cylinders. The moving ends of the pair of cylinders are fixedly connected with the supporting plate.

[0008] Furthermore, a motor is arranged on the top of the supporting plate. The output shaft of the motor is fixedly connected with a drill rod. The drill rod is in clearance fit with the reserved hole. The motor and the drill rod cooperate to form a drilling component. The number of the drilling components is four.

[0009] Furthermore, the four supporting rods respectively comprise two first cylinders and two second cylinders. The height of the first cylinder is greater than that of the second cylinder.

[0010] Furthermore, the two guiding plates are distributed in a "V" shape.

[0011] Furthermore, a supporting frame is arranged on the top of the fixing frame. The shape of the supporting frame is "field" shaped. A positioning component is arranged at the middle position of the top of the supporting frame.

[0012] The utility model has the following beneficial effects:

[0013] Through the structural design of the waste collecting box, the supporting rod, the guiding plate, the reserved hole and the frame, the utility model can guide the chips generated in the drilling process to a preset collection area, avoid the scattered chips everywhere, enable the staff to quickly and centrally clean the chips in the collection area after the drilling operation is completed, greatly shorten the cleaning time and improve the overall production efficiency.

[0014] Through the structural design of the assembly groove and the limiting member, the utility model can play a role in guiding the installation and limiting of the waste collecting box, provide convenience for the staff to place the waste collecting box, ensure the stability of the waste collecting box during the working process of the device, and ensure the effective collection of the chips.

[0015] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. [[ID=​​​Figure 1 Schematic diagram of the overall structure of the drilling device.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model provides a technical solution: a drilling device for processing the stator and rotor of a motor, comprising a fixing frame 1, a support plate 3 is provided on the fixing frame 1, a support plate 5 is installed on the support plate 3 in a liftable manner, an assembly groove 501 is opened on the support plate 5, and a waste collection box 6 is slidably fitted on the assembly groove 501.

[0023] A limiting member 7 is provided on the support plate 5 , and the limiting member 7 includes a column 701 and a limiting block 702 . The column 701 is fixed on the support plate 5 , and the limiting block 702 has a circular hole 7020 . The circular hole 7020 is clearance-matched with the column 701 , and the limiting block 702 contacts the surface of the waste collection box 6 .

[0024] In order to increase the friction force when the limit block 702 rotates and prevent the limit block 702 from rotating accidentally, the outer wall of the column 701 is provided with a rubber gasket with anti-slip grooves, and the rubber gasket is in contact with the limit block 702.

[0025] On the top of the support plate 5, there is a guiding component. The number of guiding components is two. The guiding component includes a support rod 9. There are four support rods 9 in total. On the four support rods 9, a material guiding plate 10 is inclinedly arranged. The material guiding plate 10 has reserved holes 1001. There are two reserved holes 1001. On the top of the material guiding plate 10, there is a frame 11. The shape of the frame 11 is "U".

[0026] Among them, the frame 11 includes a bottom frame. On the top of the bottom frame, there is a "U"-shaped groove. Inside the "U"-shaped groove, there is a spring. The spring is connected to the top frame. The top frame is in sliding fit with the "U"-shaped groove. During the processing, the top frame contacts the bottom of the support frame 2 to avoid the situation of debris flying centrifugally.

[0027] Among them, on the top of the support plate 5, there is a motor 8. The output shaft of the motor 8 is fixedly connected with a drill rod 801. The drill rod 801 is in clearance fit with the reserved hole 1001. The motor 8 and the drill rod 801 cooperate to form a drilling component. The number of drilling components is four. The drilling component is used to drill the fixed workpiece.

[0028] Among them, on the top of the support plate 3, there is a cylinder 4. There is a pair of cylinders 4. The moving ends of the pair of cylinders 4 are fixedly connected with a support plate 5.

[0029] In this embodiment, when processing the motor stator and rotor, first connect the external power supply and switch to the electrical equipment in this device. After fixing the motor stator and rotor to be processed, start the motor 8. The motor 8 drives the drill rod 801 to rotate. Then start the switch of the cylinder 4. The cylinder 4 works to make the support plate 5 rise, and then the drill rod 801 rises for drilling. The debris generated by drilling falls on the material guiding plate 10 under the action of gravity. Since the material guiding plate 10 is in an inclined state, the debris will finally slide off the material guiding plate 10 into the waste collection box 6. The staff only needs to regularly rotate the limit block 702 so that the limit block 702 no longer contacts the waste collection box 6, and then the waste collection box 6 can be slid out of the support plate 5 to centrally process the collected debris.

[0030] In this embodiment, as Figure 2 and Figure 4 shown, the four support rods 9 respectively include two first cylinders and two second cylinders. The height of the first cylinder is greater than that of the second cylinder, so that the two material guiding plates 10 are distributed in a "V" shape after installation, achieving the function of facilitating material guiding.

[0031] In this embodiment, as Figure 1 shown, on the top of the fixing frame 1, there is a support frame 2. The shape of the support frame 2 is "field" shaped. At the middle position of the top of the support frame 2, there is a positioning component.

[0032] In this embodiment, the structure of the positioning assembly is the same as the related structure used for installing and positioning stator and rotor punchings in the prior art (Announcement No.: CN220838046U), and will not be described in detail here.

[0033] The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention. The preferred embodiments do not describe all details in detail, nor do they limit the present invention to the specific embodiments described. Obviously, many modifications and variations are possible based on the contents of this specification. These embodiments are selected and described in detail in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. The present invention is limited only by the claims and their full scope and equivalents.
