Description

Technical Field

[0002] The coreless motor rotor comprises a coil and commutator assembly assembled as a single unit. The assembly process for the coreless motor rotor includes: spot welding, resistance testing, potting, and polishing.

[0003] When designing an automated assembly line for coreless motor rotors, corresponding spot welding stations, resistance testing stations, glue-filling stations, and polishing stations need to be set up along the production line direction. These stations are connected sequentially by a transfer track. The design of the specific transfer track and station structure must meet the following two conditions: Condition 1: The workpieces (coil and commutator assemblies) located at the spot welding, resistance testing, glue-filling, and polishing stations can rotate without displacement in other directions during rotation, to meet the process implementation requirements. Condition 2: After each process is completed, the workpieces (coil and commutator assemblies) can freely flow along the transfer track to the next process (This description only provides background information related to this utility model and does not constitute prior art).

[0024] Please refer to this carefully. Figure 1-4This utility model discloses an online lifting and rotating assembly station 100, including: a rotating lifting carrier 1, a rotating centering assembly 2, a lifting power assembly 3, and a rotating assembly 4; the upper part of the rotating lifting carrier 1 is used to support and fix the workpiece, and the rotating lifting carrier 1 has an abutment step 113; the rotating centering assembly 2 includes a rotating centering block 21, the upper part of the rotating centering block 21 is provided with a carrier receiving groove 211 that runs horizontally (i.e., the production line direction described later) through it, the carrier receiving groove 211 is used to receive the lower part of the rotating lifting carrier 1, the rotating centering assembly 2 also includes a top limiting plate 22 fixed to the top of the rotating centering block 21 and partially extending into the carrier receiving groove 211; the lifting power assembly 3 includes a lifting rotating shaft 31 and a lifting linear drive 32, wherein the lower part of the lifting rotating shaft 31 is connected to the lifting linear drive 32 and is driven to lift by the lifting linear drive 32, the lifting rotating shaft 31 The upper part passes through the rotating centering block 21 and can extend into the carrier receiving slot 211 and act on the rotating lifting carrier 1; the rotating assembly 4 includes a rotating bushing 41 fixed to the lower part of the rotating centering block 21, and a lifting rotating shaft 31 passes through the rotating bushing 41 in the middle and is slidably connected to the rotating bushing 41; the lifting rotating shaft 31 is also keyed to the rotating bushing 41 to achieve synchronous rotation of the two; the rotating assembly 4 also includes a rotating power unit 42 connected to the rotating bushing 41 and used to drive the rotating bushing 41 to rotate; the rotating lifting carrier 1 has a first state and a second state controlled and switched by the lifting linear drive 32; when the rotating lifting carrier 1 is in the first state, the abutting step 113 and the lower part of the top limiting plate 22 are spaced apart, and the rotating lifting carrier 1 is slidably connected to the carrier receiving slot 211; when the rotating lifting carrier 1 is in the second state, the abutting step 113 and the lower part of the top limiting plate 22 are abutted and fixed.

[0025] The online lifting and rotating assembly station 100 of this utility model can be used as a spot welding station, resistance testing station, glue potting station or polishing station. The structure and function of each component in this embodiment will be further explained below.

[0026] The workpiece includes coils and commutator assemblies.

[0027] The rotary lifting carrier 1 is used to load and fix the workpiece. The upper part of the rotary lifting carrier 1 is provided with a support or housing structure that cooperates with the workpiece to ensure the precise relative position of the coil and commutator assembly. The shaft hole fit dimensions of the rotary lifting carrier 1 and the workpiece (coil and commutator assembly) are reasonably designed so that the workpiece can be fitted and fixed on the upper part of the carrier, and the workpiece can move synchronously with the rotary lifting carrier 1.

[0028] The lifting linear drive 32 is used to provide lifting driving power to drive the lifting rotating shaft 31 to slide upward along the rotating bushing 41 and push the rotating lifting vehicle 1 upward until it abuts against the step 113 and the lower part of the top limiting plate 22 and is fixed, and the rotating lifting vehicle 1 is in the second state.

[0029] The rotary power unit 42 provides rotary drive power to drive the rotary bushing 41 and the rotary centering block 21 to rotate as a whole. When the rotary lifting carrier 1 is in the second state, the rotary lifting carrier 1 carries the workpiece and rotates with the rotary centering block 21, ensuring that the workpiece rotates along a predetermined trajectory, thereby ensuring the accuracy of spot welding, resistance testing, glue application, and polishing processes. For example, during spot welding, if the rotation trajectory of the workpiece is accurate, the spot welding gun can accurately land at the predetermined position, ensuring the accuracy of spot welding.

[0030] After the corresponding process is completed, the lifting linear drive 32 drives the lifting rotary shaft 31 to slide downward along the rotary bushing 41, and the rotary lifting carrier 1 descends, abutting the lower part of the step 113 and the top limiting plate 22 at intervals. The rotary lifting carrier 1 is in the first state. In this state, the rotary lifting carrier 1 has the freedom to slide along the carrier receiving groove 211. Using external power (such as a material feeding plate), the rotary lifting carrier 1 and the workpiece can be moved along the extension direction of the carrier receiving groove 211. When the extension direction of the carrier receiving groove 211 is consistent with the production line direction, and a transfer track 06 is set between adjacent workstations, the workpiece can be transferred between each workstation.

[0031] As can be seen from the above, the rotary lifting carrier 1 used for loading and fixing workpieces according to this utility model has a first state and a second state that can be freely switched. In the second state, the workpieces (coil and commutator assembly) located at the spot welding station, resistance detection station, glue filling station and polishing station can rotate, and the workpieces do not undergo displacement in other directions when rotating, ensuring the accuracy of the operation; after completing each process, the rotary lifting carrier 1 switches to the first state, and the workpieces (coil and commutator assembly) can flow freely along the flow track 06 to the next process; thus well meeting the needs of the rotor automatic assembly line.

[0032] According to a specific embodiment of this utility model, the rotating lifting carrier 1 includes: a carrier base 11, a carrier mold core 12, and a lateral locking screw 13; the carrier base 11 includes an upper base section 111 and a lower base section 112 fixed vertically, and the stepped surface between the upper base section 111 and the lower base section 112 is an abutting step 113; the carrier base 11 is provided with a mold core insertion hole 114 passing through it, and the lower part of the carrier mold core 12 is inserted into the mold core insertion hole 114; the base The upper section 111 has a locking screw hole 1111 on its outer side that connects to the mold core insertion hole 114. The lateral locking screw 13 is screwed into the locking screw hole 1111 and its end abuts against the outer wall of the fixed carrier mold core 12. The carrier mold core 12 is a hollow cylinder. The workpiece includes a coil and a commutator assembly. The commutator assembly includes a rotor shaft that is cylindrical in shape. The outer diameter of the carrier mold core 12 matches the inner diameter of the coil, and the inner diameter of the carrier mold core 12 matches the outer diameter of the rotor shaft.

[0033] In this embodiment, the rotating lifting carrier 1 is a split structure. The depth to which the carrier mold core 12 is inserted into the mold core insertion hole 114 is adjustable to match different coil heights. After the relative positions of the carrier base 11 and the carrier mold core 12 are determined, they are locked and fixed by the lateral locking screws 13. The inner diameter of the carrier mold core 12 matches the outer diameter of the rotor shaft, that is, when the rotor shaft is inserted into the inner hole of the carrier mold core 12, the distance between the rotor shaft and the inner hole of the carrier mold core 12 is small, and the rotor shaft is held and fixed after insertion. The outer diameter of the carrier mold core 12 matches the inner diameter of the coil, that is, after the coil is sleeved on the outside of the carrier mold core 12, the gap between the coil and the carrier mold core 12 is small, and the coil is held and fixed on the carrier mold core 12.

[0034] As can be seen from the above, the rotary lifting carrier 1 of this embodiment can stably load workpieces and can be adapted to coils of the same diameter but different heights.

[0035] According to a specific embodiment of the present invention, there are two top limiting plates 22, which are symmetrically arranged on the upper sides of the carrier receiving groove 211. Each top limiting plate 22 is provided with an abutting step 113 below it.

[0036] In this embodiment, two top limiting plates 22 are arranged in a one-to-one correspondence with two abutting steps 113; when the rotating lifting vehicle 1 is in the second state, the abutting steps 113 on both sides of the rotating lifting vehicle 1 abut against the two top limiting plates 22 respectively. With this structure, symmetrical force can be ensured and the stability of the abutting fixation can be improved.

[0037] According to a specific embodiment of the present invention, the rotating centering block 21 is cylindrical in shape, the top limiting plate 22 is fan-shaped in shape, and the arc-shaped outer side of the top limiting plate 22 is aligned with the outer side of the rotating centering block 21.

[0038] In this embodiment, the top limiting plate 22 is fan-shaped and its arc-shaped outer side is aligned with the outer side of the rotating centering block 21, which helps to improve compactness.

[0039] According to a specific embodiment of the present invention, the lower section 112 of the base is slidably connected to the vehicle receiving groove 211. The cross-section of the lower section 112 of the base is square. Any pair of opposite outer surfaces of the lower section 112 of the base correspond one-to-one with and fit against the two side walls of the vehicle receiving groove 211.

[0040] In this embodiment, the two side walls of the carrier receiving groove 211 serve as sliding guides for the lower section 112 of the base, ensuring that the carrier base 11 is accurately positioned within a predetermined location. This facilitates smooth switching of the rotating and lifting carrier 1 between states and allows for smooth movement within the transfer track 06. The lower section 112 has a square cross-section, allowing any pair of opposite outer surfaces of the lower section 112 to be used as sliding guides. This facilitates direct switching from one transfer track 06 to another vertical transfer track 06, making it suitable for use in rectangular return production lines.

[0041] According to a specific embodiment of the present invention, the upper inner wall of the rotating bushing 41 is provided with a flat keyway 411, and the outer wall of the lifting rotating shaft 31 is provided with a connecting key 43. The position where the lifting rotating shaft 31 is embedded in the connecting key 43 forms a protruding shoulder 311. The connecting key 43 is also slidably connected in the flat keyway 411 to realize the key connection between the lifting rotating shaft 31 and the rotating bushing 41.

[0042] In this embodiment, the connecting key 43 is a flat key. When the lifting and rotating shaft 31 is raised and lowered, the connecting key 43 slides along the flat keyway 411 to ensure that the lifting and rotating shaft 31 and the rotating bushing 41 are always in a stable key connection state.

[0043] According to a specific embodiment of the present invention, the rotating assembly 4 further includes a limiting flange 44 that is fixedly connected to the rotating centering block 21 and the rotating bushing 41 and located between the two. The top of the limiting flange 44 is provided with a recessed centering block positioning groove 441, and the lower part of the rotating centering block 21 is installed in the centering block positioning groove 441.

[0044] In this embodiment, the limiting flange 44 has several functions: on the one hand, the limiting flange 44 can be used to restrict the shoulder 311 from coming off upward, which is conducive to the modular assembly of this utility model; on the other hand, the centering block positioning groove 441 on the limiting flange 44 is used for the installation and positioning of the rotating centering block 21, which is conducive to quick positioning during assembly, and can also restrict the lateral movement of the rotating positioning block to ensure the accuracy of the position of the rotating centering block 21.

[0045] According to a specific embodiment of the present invention, the lifting power assembly 3 further includes a floating joint 33, and the lifting linear drive 32 is connected to the lower end of the lifting rotating shaft 31 via the floating joint 33; the rotating assembly 4 further includes a rotating bearing seat 45; the rotating bearing seat 45 is sleeved outside the rotating shaft sleeve 41, and the rotating bearing seat 45 and the rotating shaft sleeve 41 are rotatably connected by a bearing 46.

[0046] In this embodiment, the structure in which the rotating bearing seat 45 and the bearing 46 cooperate provide rotational support for the rotating bushing 41. During use, the rotating bearing seat 45 is fixedly installed. The structure that uses the floating joint 33 to connect the lifting rotating shaft 31 and the lifting linear power can compensate for deviations and avoid rigid collisions, so that the lifting force of the lifting rotating shaft 31 on the carrier base 11 is an elastic clamping force, ensuring that when the rotating lifting carrier 1 is in the second state, the abutment step 113 can press against the top limiting plate 22.

[0047] According to a specific embodiment of this utility model, the online lifting and rotating assembly station 100 also includes a base assembly 5 with an overall frame structure; the base assembly 5 includes: a small base plate 51, a lifting cylinder mounting plate 52 and a side plate 53, the small base plate 51 and the lifting cylinder mounting plate 52 are arranged vertically at intervals, the side plate 53 is fixedly connected to the small base plate 51 and the lifting cylinder mounting plate 52, the lower part of the rotating bearing seat 45 is fixed on the small base plate 51; the lifting linear drive 32 is mounted on the lifting cylinder mounting plate 52.

[0048] In this embodiment, the base assembly 5 is used to provide an installation foundation, to fix and support the rotary bearing seat 45, and to install the lifting cylinder.

[0049] According to a specific embodiment of this utility model, the online lifting and rotating assembly station 100 further includes a motor mounting plate 55. The rotating power unit 42 includes a rotating motor 421, a coupling 422, and a drive gear 423 connected sequentially from bottom to top.

The upper part of the lifting cylinder mounting plate 52 is provided with a recessed motor plate sliding receiving groove 521. The motor mounting plate 55 is slidably connected in the motor plate sliding receiving groove 521, and the rotating motor 421 is mounted on the motor mounting plate 55. On one side of the lifting cylinder mounting plate 52, a vertically arranged tensioning plate 54 is also fixed. The tensioning plate 54 is provided with a tensioning adjusting screw 56 for adjusting the distance between the driving gear 423 and the driven gear 424. One end of the tensioning adjusting screw 56 is threadedly connected to the tensioning plate 54, and the other end of the tensioning adjusting screw 56 abuts against the motor mounting plate 55. The lifting cylinder mounting plate 52 is also provided with a waist-shaped adjusting hole 522. The online lifting and rotating assembly station 100 also includes a connecting bolt 57 that passes through the waist-shaped adjusting hole 522 and extends into the motor mounting plate 55 for fixing the motor mounting plate 55 and the lifting cylinder mounting plate 52.

[0050] In this embodiment, the direction in which the center of the driving gear 423 approaches or moves away from the center of the driven gear 424 is the gear tensioning direction. The sliding direction of the motor mounting plate 55, the gear tensioning direction, and the extension / retraction adjustment direction of the tension adjusting screw 56 are the same. The rotary motor 421 is mounted on the motor mounting plate 55. By extending and retracting the tension adjusting screw 56, the position of the rotary motor 421 can be adjusted, thereby adjusting the distance between the driving gear 423 and the driven gear 424, which helps to improve the flexibility of assembly. After adjusting to a suitable distance, the connecting bolts 57 are tightened to fix the motor mounting plate 55 and the lifting cylinder mounting plate 52.
