Description

Technical Field

[0001] This invention relates to the field of tooling and fixture technology, specifically a terminal-fixed stator energizing tooling and fixture. Background Technology

[0002] The stator is one of the core components of rotating machinery such as motors and generators. The stator is the stationary part of a motor or rotating machinery, which works in conjunction with the rotating rotor to achieve energy conversion through electromagnetic induction or magnetic field interaction. In motors (such as AC motors and DC motors), the stator windings generate a rotating magnetic field (AC motor) or a fixed magnetic field (DC motor) after being energized. This magnetic field interacts with the rotor magnetic field, causing the rotor to rotate and thus output mechanical energy.

[0003] Tooling fixtures are auxiliary devices used in manufacturing to fix, position, clamp workpieces or guide cutting tools to ensure the accuracy, efficiency and safety of machining, assembly, inspection and other processes.

[0004] Currently, existing stator tooling fixtures have high operating costs and are difficult to implement self-locking and automatic locking functions, which prevents the copper plates from making sufficient contact and causes arcing on the end face. Furthermore, the stator needs to be fed with external guide components before clamping, which requires additional energy for the clamping operation. Therefore, an improved device is needed to address these issues. Summary of the Invention

[0016] The beneficial effects of this invention are:

[0017] First, the present invention utilizes an electric fixture consisting of a pair of electric female and electric male connectors, three sets of first flexible copper electrodes, three sets of adjusting copper electrodes, and a high-temperature resistant spring. In operation, the electric female connector engages with the electric male connector under the action of a cylinder, forming a primary electrical conduction structure that can attract and restrict the stator. Simultaneously, the electric male connector connects to the three sets of second flexible copper electrodes, and the adjusting copper electrodes pass through the high-temperature resistant springs and are connected to the second flexible copper electrodes via shaft screws, forming a secondary electrical conduction structure that enhances the positioning and restriction strength of the stator, thus completing the dual positioning of the stator.

[0018] Second, this invention employs a separate design for the support base plate and the crossbar, facilitating the subsequent removal of the support base plate. Simultaneously, when the support base plate moves downward to its limit position, a photoelectric sensor activates a fan, which blows air onto the stator on the support base plate to cool it. Furthermore, when the extension arm moves downward to its limit position, the U-shaped support rod is pressed upward by the contact plate, allowing it to be removed from the inside of the crossbar for easy removal of the support base plate. Additionally, during displacement, the gripper arm can move the support vertical plate on the surface of the transmission gear via the movable connecting arm, thereby causing the extension arm to move upward. This allows the support base plate to move the stator upward, achieving synchronized stator conveying and upward movement. Attached Figure Description

Detailed Implementation

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] The invention will be further described below with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1 , Figure 2 and Figure 3As shown, the terminal-fixed stator energizing fixture of the present invention includes a clamping cylinder 14. Clamping arms 10 are installed inside both ends of the clamping cylinder 14. A clamping block 9 is fixedly installed at one opposite end of each clamping arm 10. A lower lifting cylinder 18 is fixedly installed at the top of the clamping cylinder 14. A floating insulating plate 15 is fixedly installed at the front end of the lower lifting cylinder 18. An energizing female connector 1 is fixedly installed equidistantly inside the floating insulating plate 15. Four lower cylinder positioning shafts 20 are installed at the top of the lower lifting cylinder 18. A second linear bearing 19 is slidably sleeved on the outer ring of each lower cylinder positioning shaft 20. An upper energizing cylinder 12 is fixedly installed at the bottom end of the lower lifting cylinder 18. The front end of the upper energizing cylinder 12 is fixedly installed... An insulating block 8 is provided. A second flexible copper electrode 6 is fixedly installed at equal intervals on the top of the insulating block 8. A first flexible copper electrode 3 is installed on the top of the second flexible copper electrode 6. An adjusting copper electrode 4 is installed inside the first flexible copper electrode 3. A shaft screw 5 is provided on the surface of the adjusting copper electrode 4. A high-temperature resistant spring 7 is provided on the top of the shaft screw 5. A power-conducting male connector 2 is fixedly installed on the top of the rear end of the insulating block 8. An upper cylinder positioning shaft 16 and a first linear bearing 17 are symmetrically fixedly installed on the bottom end of the lower lifting cylinder 18. The first linear bearing 17 is located on the outer ring of the upper cylinder positioning shaft 16. A push plate 11 is fixedly installed on the bottom side of the lower lifting cylinder 18. A propulsion cylinder 13 is fixedly installed on the top side of the clamping cylinder 14.

[0033] The working principle of Example 1 is as follows: In use, the power-conducting fixture consists of a pair of power-conducting female connectors 1 and male connectors 2, three sets of first flexible copper electrodes 3, three sets of adjusting copper electrodes 4, and a high-temperature resistant spring 7. In the working state, the power-conducting female connector 1 will combine with the power-conducting male connector 2 under the action of the upper power-conducting cylinder 12, forming a primary electrical conduction structure. At the same time, the power-conducting male connector 2 is connected to the three sets of second flexible copper electrodes 6. The adjusting copper electrodes 4 pass through the high-temperature resistant spring 7 and are connected to the second flexible copper electrodes 6 through the shaft screw 5, forming a secondary electrical conduction structure. After the stator automatically flows to the equipment, it is first fully connected to the stator through the secondary conductive mechanism, and then connected to the secondary electrical conduction structure through the primary electrical conduction structure. Finally, the power supply transmits DC power to the primary electrical conduction structure through the connected wires, and then flows through the first flexible copper electrode 3. Through the spring between it and the adjusting copper electrode 4, it is pre-compressed and tightly connected to the contact surface of the three-phase copper plates of the stator. Finally, it returns through the stator copper coil to form a closed loop, so that the stator is heated to the required working temperature.

[0034] Example 2

[0035] Based on Example 1, such as Figure 4 As shown, the clamping cylinder 14 includes a contact device 21, a guide device 22, and a transmission device 23. The transmission device 23 is fixedly installed at both ends of the clamping cylinder 14, and the guide device 22 is fixedly installed at the bottom front end of the clamping cylinder 14. The contact device 21 is slidably placed between the two transmission devices 23.

[0036] like Figure 5 The contact device 21 includes a crossbar 24, a locking key 25, an insulating pad 26, and a supporting base plate 27. The locking key 25 is symmetrically fixedly installed at the bottom end of the supporting base plate 27, the crossbar 24 is fixedly installed at the top of both ends of the supporting base plate 27, and the insulating pad 26 is symmetrically fixedly installed on the inner ring of the supporting base plate 27. The gap between the insulating pad 26 and the supporting base plate 27 facilitates the support of the stator for cooling.

[0037] like Figure 6 The guiding device 22 includes a fan 28, a limiting plate 29, a photoelectric sensor 30, a guide plate 31, and a docking contact plate 32. The limiting plate 29 is fixedly installed at the bottom front end of the fan 28, the guide plate 31 is fixedly installed at the front end of the limiting plate 29, the docking contact plate 32 is symmetrically fixedly installed at the rear ends of both sides of the guide plate 31, and the photoelectric sensor 30 is fixedly installed at the top rear end of the guide plate 31. Through the setting of the guide plate 31, the supporting base plate 27 can be supported to slide along a straight line.

[0038] like Figure 7 and Figure 8 The transmission device 23 includes a movable connecting arm 33, a supporting vertical plate 34, a first rack 35, a second rack 36, an extension bracket 37, a transmission gear 38, an extension arm 39, a supporting base 40, a positioning cavity 41, a return spring 42, a U-shaped support rod 43, and a crossbeam 44. The movable connecting arm 33 is slidably inserted into the interior of the supporting vertical plate 34. The first rack 35 is fixedly installed at one end of the movable connecting arm 33. The supporting base 40 is symmetrically fixedly installed at the bottom of the side end of the supporting vertical plate 34 away from the movable connecting arm 33. The transmission gear 38 is rotatably installed between the two supporting bases 40. The extension bracket 37 is fixedly installed on the supporting vertical plate 34. The vertical plate 34 is located above the side end of the supporting base 40. The second rack 36 is slidably inserted into the end of the extension bracket 37 away from the supporting vertical plate 34. The extension arm 39 is fixedly installed at the bottom end of the second rack 36. The horizontal frame 44 is fixedly installed at the end of the extension arm 39 away from the extension bracket 37. The positioning cavity 41 is symmetrically fixedly installed at the top end of the horizontal frame 44. The U-shaped support rod 43 is slidably inserted into the inside of the positioning cavity 41. The return spring 42 is fixedly installed between the positioning cavity 41 and the U-shaped support rod 43. The first rack 35 is located between the two second racks 36, so that the first rack 35 and the second rack 36 can avoid interference between each other.

[0039] A crossbar 24 is placed at the top of the cross frame 44. Supporting vertical plates 34 are fixedly installed at both ends of the clamping cylinder 14. A blower 28 is fixedly installed at the bottom front end of the clamping cylinder 14. A support rod is fixedly installed between the insulating pad 26 and the supporting base plate 27. The extension bracket 37 has symmetrically formed slots inside, away from the supporting vertical plate 34. A locking key is fixedly installed on the side end of the second rack 36 opposite to the transmission gear 38. Vertical holes are formed inside both the crossbar 24 and the cross frame 44. The U-shaped support rod 43 is located away from the positioning cavity 41. One end of the bottom is vertically aligned with the docking contact plate 32. The top of the guide plate 31 is symmetrically provided with movable slots. The photoelectric sensor 30 is vertically aligned with the bottom center of the support base plate 27. The first rack 35 and the second rack 36 are respectively meshed with the transmission gear 38, and the second rack 36 is located on both sides of the first rack 35. The end of the movable connecting arm 33 away from the second rack 36 is fixedly installed with a flange. A square plate is fixedly installed on the outer ring of one end of the U-shaped support rod 43, and the square plate is located at the top of the inside of the positioning cavity 41.

[0040] In implementing this embodiment, the stator can be temporarily placed on top of the insulating pad 26. Then, the flange at the end of the movable connecting arm 33 furthest from the first rack 35 is connected to the gripper arm 10. This allows the gripper arm 10 to move synchronously with the first rack 35 via the movable connecting arm 33. When the gripper arm 10 needs to hold the stator, it can move the first rack 35 towards the end closer to the supporting vertical plate 34 at the top of the transmission gear 38. The movable connecting arm 33 slides inside the supporting vertical plate 34, supporting its linear displacement. When the first rack 35 moves towards the end closer to the supporting vertical plate 34, it can drive the second rack 36 towards the end via the transmission gear 38. The upward displacement is achieved through the extension arm 39 connected to the second rack 36. When the second rack 36 moves upward, it can support the crossbeam 44 via the extension arm 39, which contacts the crossbar 24. This causes the support base plate 27 to lift upward as a whole, thereby moving the stator to contact the clamping block 9. Simultaneously, when the clamping block 9 fully clamps the stator, the support base plate 27 can move upward to its limit position, thus providing auxiliary support at the bottom of the stator. Furthermore, the insulating pad 26 prevents electric shock. Subsequently, when the stator has finished processing, the clamping cylinder 14 can be operated to move the gripper arm 10 outward. At this time, the gripper arm 10 can move the movable connecting arm 33 and the first rack 35 away from the support vertical plate 34. Thus, the first rack 35 can move again along the top of the transmission gear 38, and the transmission gear 38 drives the second rack 36 to move downward. At this time, the key on the side of the second rack 36 moves in the slot inside the side of the extension bracket 37, so that the second rack 36 can move up and down in a straight line, improving the meshing stability of the second rack 36 and the transmission gear 38. When the second rack 36 moves downward, the extension arm 39 can drive the crossbeam 44 to move downward. Thus, while the gripper arm 10 releases the stator, the support base plate 27 can drive the stator to move downward. When the gripper arm 10 is fully reset, the support base plate 27 can move downward to contact the top of the guide plate 31. The bottom of the support base plate 27 contacts the photoelectric sensor 30, and the photoelectric sensor 30... The support plate 27 is electrically connected to the fan 28, allowing the fan 28 to be started. The fan 28 is horizontally aligned with the support base plate 27, enabling it to blow air onto the stator on the support base plate 27 for rapid cooling. Simultaneously, when the support base plate 27 moves downwards to contact the top of the guide plate 31, the bottom end of the U-shaped support rod 43, away from the positioning cavity 41, is vertically aligned with the mating contact plate 32. This allows the U-shaped support rod 43 to be compressed and restricted by the mating contact plate 32. When the support base plate 27 moves downwards to its limit, the U-shaped support rod 43 can move upwards, causing its bottom end near the positioning cavity 41 to move out of the crossbeam 44 and crossbar 24, releasing the support base plate 27. After the stator has completely cooled down...The user can drag the support base plate 27 to the end away from the fan 28, which facilitates the removal of the stator. Simultaneously, as the support base plate 27 moves forward, it moves within the movable groove at the top of the guide plate 31 via the locking key 25, ensuring that the support base plate 27 moves in a straight line. When the support base plate 27 is at the top of the guide plate 31, it disengages from the photoelectric sensor 30, causing the photoelectric sensor 30 to lose its sensing signal and thus de-energizing the fan 28, preventing energy waste. After removing the processed stator, other stators requiring processing are placed on the insulating pad 26. The support base plate 27 is then slid towards the end closer to the fan 28 until it contacts the limiting plate 29. The contact allows the vertical holes inside the crossbar 24 and the crossarm 44 to align. Then, when the gripper arm 10 drives the extension arm 39 upward again, the crossarm 44, positioned below the crossbar 24, supports the crossbar 24, causing the support base plate 27 to move upward. As the extension arm 39 moves upward, the U-shaped support rod 43 gradually disengages from the contact plate 32. The elasticity of the return spring 42 causes the U-shaped support rod 43 to move downward and reset, allowing it to re-insert into the vertical holes inside the crossarm 24 and the crossarm 24. This prevents the crossbar 24 from sliding again on the crossarm 44, completing the connection and adaptation between the support base plate 27 and the extension arm 39.

[0041] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
