Description

Technical Field

[0001] This invention belongs to the field of motor end mounting, specifically relating to an installation process for a motor end cone ring and a connecting copper tube. Background Technology

[0002] The parallel ring assembly at the end of a large motor (multiple connecting copper tubes installed on the outer circumference of a conical ring to form a parallel ring assembly) can suppress rotor oscillation, especially in the event of sudden load changes or grid disturbances, helping the motor to quickly restore synchronous speed. As a structural support, the parallel ring enhances the mechanical strength of the rotor end and prevents deformation of the conductor bars or windings. Moreover, in large motors, the two ends of the rotor conductor bars are short-circuited through the parallel ring to form a closed loop. During startup, the rotor conductor bars cut the rotating magnetic field to generate induced current. The parallel ring ensures that the current is evenly distributed, thereby generating a larger starting torque. By optimizing the magnetic field distribution, the current surge during startup is indirectly reduced.

[0003] The outer circumference of the conical ring of the parallel ring assembly requires the installation of multiple arc-shaped connecting copper tubes. These connecting copper tubes have excellent conductivity, efficiently transmit current, and reduce energy loss at the connection points. The tubular structure of the connecting copper tubes can enhance heat dissipation through natural convection or forced air cooling. The multiple connecting copper tubes are non-closed arc structures and need to be arranged in a circular shape and installed on the outer circumference of the parallel ring.

[0004] In large motors, multiple parallel copper tubes are installed on the outer circumference of a conical ring, which can have a diameter of up to 3.5m. When installing the parallel copper tubes and conical tubes, the pre-installation positions are typically determined manually on the outer circumference of the conical ring and marked. A bakelite bracket is then manually installed, and the multiple connecting copper tubes are positioned within the limiting grooves of the bakelite bracket and secured to the conical ring by binding. This structure provides some mechanical support and insulation, but it has the following mechanical defects: 1. Manually measuring and marking the position of the bakelite bracket introduces a certain degree of positional deviation, making it impossible to guarantee the concentricity of the connecting copper tubes and the conical ring. If the concentricity is off, the length, bending radius, and impedance of each connecting copper tube will be inconsistent, leading to uneven current distribution and increased stress on the connecting copper tubes. 1. Uneven force distribution causes some connecting copper tubes to bear greater mechanical stress. After the motor starts running, the electromagnetic force or mechanical vibration at high speed can cause cracks in the connecting copper tubes, posing a risk of breakage. Therefore, manual measurement and positioning are extremely important, requiring repeated measurements and positioning, resulting in high labor intensity. 2. Although bakelite brackets have good insulation, their mechanical strength is low. Under long-term vibration or thermal stress, they are prone to cracking or vibration, causing the connection between the bakelite bracket and the cone ring to loosen. This leads to displacement of the connecting copper tubes, affecting the motor's conductivity. At the same time, the loose connection causes a sharp increase in resistance, leading to motor overheating and accelerating motor aging. 3. Traditional binding methods mainly rely on fiberglass tape to bind the connecting copper tubes and then impregnate and cure them to enhance the connection rigidity. The binding structure relies on impregnation and curing to achieve the connection. This connection method can lead to loosening due to mechanical impact or thermal expansion and contraction.

[0005] Therefore, the current installation process of the motor end cone ring and connecting copper pipe has defects such as difficulty in ensuring installation concentricity, and loosening at the connection between the bakelite bracket and the cone ring, as well as at the binding connection between the bakelite bracket and the connecting copper pipe. Summary of the Invention

[0006] The purpose of this invention is to overcome the above shortcomings and provide an installation process for the motor end cone ring and the connecting copper tube, which can quickly achieve installation concentricity, avoid loosening of the connection due to mechanical impact or thermal expansion and contraction, reduce contact resistance, and prevent the motor from overheating and aging.

[0007] The objective of this invention is achieved through the following technical solution: an installation process for the motor end cone ring and the connecting copper tube, the specific steps of which include,

[0008] S1. Concentric Positioning Installation Device: The concentric installation device includes multiple equally spaced conical ring guide positioning structures distributed circumferentially, and a copper tube concentric limiting support structure is set between two adjacent conical ring guide positioning structures. The multiple conical ring guide positioning structures and the multiple copper tube concentric limiting support structures are concentrically set.

[0009] S2, Positioning Conical Ring: Position the conical ring from top to bottom into the conical ring guide positioning structure and clamp the conical ring;

[0010] S3. Positioning Copper Tube Concentric Limiting Support Structure: The copper tube concentric limiting support structure includes a sliding seat, a copper tube limiting assembly placed on the sliding seat, and a locking assembly that presses the copper tube limiting assembly against the outer wall of the cone ring; a conformal rope is glued to the position of the copper tube limiting assembly near the outer wall of the cone ring, and multiple copper tube limiting assemblies move toward the outer wall of the cone ring;

[0011] S4. Fix the copper tube limiting assembly and the cone ring: The locking assembly presses the copper tube limiting assembly against the outer wall of the cone ring, the screw passes through the copper tube limiting assembly into the cone ring and is locked and fixed by the nut, and polyester felt is glued and embedded around the nut. The polyester felt is filled with an insulating plate and left to stand for 12-18 hours.

[0012] S5. Install connecting copper pipes: Buffer polyester felt is glued at the contact position between the copper pipe limiting component and the connecting copper pipe. Each connecting copper pipe is horizontally embedded in the corresponding copper pipe limiting component. Select glass fiber tape impregnated with epoxy resin and bind and fix the connecting copper pipe to the corresponding copper pipe limiting component by cross binding. Multiple connecting copper pipes are distributed in a staggered manner from top to bottom on the outer circumference of the conical ring and form a ring structure to complete the installation of the connecting copper pipes of the motor end conical ring.

[0013] S6. Remove the clamping of the locking assembly on the copper tube limiting assembly and the clamping of the conical ring guide positioning structure on the conical ring, and lift the conical ring with the connecting copper tube off the concentric installation device as a whole.

[0014] A further improvement of the present invention is that the concentric installation device further includes an annular base, and multiple conical ring guide positioning structures and multiple copper tube concentric limiting support structures are arranged on the annular base at equal circumference intervals, and the multiple conical ring guide positioning structures, multiple copper tube concentric limiting support structures, and annular base are arranged concentrically.

[0015] A further improvement of the present invention is that: the copper tube limiting assembly includes two glass fiber limiting blocks disposed on a sliding seat; the glass fiber limiting blocks on the sliding seat are circumferentially distributed at equal intervals and concentrically disposed with the annular base; the end face of the glass fiber limiting block near the conical ring has multiple grooves for embedding conformal cords; the outer end face of the glass fiber limiting block away from the conical ring has multiple limiting grooves for embedding copper tubes; the multiple limiting grooves on each glass fiber limiting block are distributed sequentially from top to bottom; and the glass fiber limiting block has a thread for a screw to pass through. The fiberglass limiting block has rectangular through holes for accommodating nuts and polyester felt. These rectangular through holes are connected to threaded holes. The fiberglass limiting block also has multiple evenly distributed strapping through holes. Each limiting groove has two strapping through holes on its rear side, and the leading edge of the upper strapping through hole has a strapping perforation. The extension direction of the strapping through holes and the strapping perforation is consistent with the extension direction of the limiting groove. The fiberglass tape cross-binds the connecting copper tube embedded in the limiting groove through two corresponding strapping through holes and one corresponding strapping perforation.

[0016] A further improvement of the present invention lies in the binding method of the glass fiber tape in step S5, specifically including the following steps:

[0017] S51. After the epoxy resin-impregnated glass fiber tape is cured, it is passed through the upper binding strap through hole and binding strap perforation, wrapped 3-5 layers in the circumferential direction and then cut to form a wrapped base layer. The beginning and end ends of the glass fiber tape are embedded in the bottom of the base layer.

[0018] S52. Pull the fiberglass tape from the upper binding hole through the connecting copper tube to the opposite end of the lower binding hole, pass through the lower binding hole, and then pull it back through the connecting copper tube to the opposite end of the upper binding hole, forming an X-shaped binding track on the outer end face of the connecting copper tube. After 3-5 layers of cyclic wrapping, cut it to form a wrapping binding layer. The beginning and end sections of the fiberglass tape are embedded at the bottom of the wrapping binding layer.

[0019] A further improvement of the present invention is that: the bottom of the glass fiber limiting block has a groove, and the sliding seat has a rib that cooperates with the groove; the extending directions of the rib and the groove are consistent with the sliding direction of the sliding seat.

[0020] A further improvement of the present invention is that: the locking assembly includes two U-shaped blocks disposed on the sliding seat, the outer ends of the U-shaped blocks having horizontal fixing blocks, the horizontal fixing blocks being fixed to the sliding seat by bolts, the two U-shaped blocks respectively covering the lower front end positions of two glass fiber limiting blocks on the sliding seat, and a stop block disposed between the two U-shaped blocks and the two glass fiber limiting blocks; the locking assembly also includes clamping blocks disposed on both sides of the two glass fiber limiting blocks, the two clamping blocks being moved toward each other or backwards by a synchronous clamping member, thereby clamping or releasing the two glass fiber limiting blocks.

[0021] A further improvement of the present invention is that: the synchronous clamping member includes a driving cavity disposed in the sliding seat, the bottom of the driving cavity has an electric push rod, the lower end of the clamping block extends vertically toward the driving cavity with a connecting plate, the bottom of the driving cavity is movably connected to a swing plate, the center of the swing plate is movably connected to the bottom of the driving cavity, the driving end of the electric push rod is movably connected to the end of the swing plate, and a connecting rod is movably connected between the connecting plate and the swing plate. The two connecting rods are respectively disposed on both sides of the center of the swing plate. When the electric push rod extends or retracts, it drives the swing plate to reciprocate about the center point as the hinge point, thereby causing the two connecting rods to pull the corresponding clamping blocks to move in opposite directions or in opposite directions.

[0022] A further improvement of the present invention is that: the lower end of the clamping block has a slider, and the sliding seat has a slide rail connected to the slider, the extension direction of the slide rail being perpendicular to the moving direction of the glass fiber limiting block.

[0023] A further improvement of the present invention is that: the conical ring guide positioning assembly includes an outer clamping seat disposed on an annular base, an inner clamping seat on the inner side of the outer clamping seat, a space for longitudinal embedding of the conical ring between the inner clamping seat and the outer clamping seat, an electric push rod II between the inner clamping seat and the annular base, the driving end of the electric push rod II being connected to the inner clamping seat, the inner clamping seat being disposed on the inner side of the conical ring, and the outer clamping seat being disposed on the outer side of the conical ring, the inner clamping seat clamping or releasing the conical ring under the extension and retraction action of the electric push rod II.

[0024] A further improvement of the present invention is that: the inner wall of the outer card seat in contact with the cone ring includes a guide arc surface one and an inclined contact surface one from top to bottom; the inner wall of the inner card seat in contact with the cone ring includes a guide arc surface two and an inclined contact surface two from top to bottom; and the top of the outer card seat is higher than the top of the inner card seat.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] 1. In this invention, when installing the motor end conical ring and connecting copper pipe, the conical ring is first hoisted onto multiple conical ring guide positioning structures. Since the conical ring guide structure and multiple copper pipe concentric limiting support structures are concentrically set, the conical ring is positioned and clamped on the conical ring guide positioning structure. The copper pipe limiting component for positioning the connecting copper pipe is fixed on the sliding seat under the clamping force of the locking component and moves towards the conical ring on the sliding seat. This achieves synchronous concentric movement of multiple copper pipe concentric limiting support structures towards the conical ring, thus ensuring the concentricity of the conical ring and multiple connecting copper pipes. It eliminates the need for manual measurement and marking, quickly achieving installation concentricity and greatly improving installation efficiency. It also effectively ensures the uniformity of the subsequent current distribution of the large motor and the mechanical stability of the connecting copper pipe.

[0027] 2. In this invention, the bakelite support connecting the copper tube and the conical ring is replaced with a fiberglass limiting block. The fiberglass limiting block and the conical ring are fixed by a screw and a nut. The fiberglass limiting block and the connecting copper tube are then bound and fixed by a fiberglass tape impregnated with resin. The screw ensures tight contact between the connecting copper tube and the conical ring through pre-tightening force, reducing contact resistance and preventing motor overheating. The screw provides rigid fixation to prevent displacement of the connecting copper tube and the conical ring under large vibrations or impacts. The fiberglass tape evenly distributes the surface pressure of the connecting copper tube, avoiding local stress concentration on the screw that could lead to screw deformation or cracking.

[0028] 3. Compared to traditional bakelite brackets, the fiberglass limiting block in this invention has high mechanical strength and high heat resistance. It is less prone to micro-cracks under long-term alternating stress, making it suitable for the high-frequency vibration environment of high-speed motors. Fiberglass has low moisture absorption, resulting in slower insulation performance degradation in humid environments, avoiding the insulation degradation problem caused by moisture absorption in bakelite brackets. Moreover, it is suitable for environments with high current-induced temperature rise, reducing the risk of thermal deformation and mitigating uneven contact stress caused by thermal expansion and contraction. Therefore, when installing the conical ring and connecting copper tube in this invention, a concentric installation device with a specific structure is used to replace the traditional bakelite bracket. A special fixing method using screws and impregnated fiberglass tape is employed to quickly achieve installation concentricity, preventing loosening of the connection due to mechanical impact or thermal expansion and contraction, reducing contact resistance, and preventing motor overheating and aging.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can be described as a mechanical connection, a direct connection, or a connection through an intermediate medium. Those skilled in the art can understand the basic meaning of the above terms in this invention according to the specific circumstances.

[0045] An installation process for the motor end cone ring and connecting copper tube, referring to... Figure 1 , Figure 2 The specific steps include,

[0046] S1. Concentric Positioning Installation Device: The concentric installation device includes multiple equally spaced conical ring guide positioning structures 3, and a copper tube concentric limiting support structure 4 is set between two adjacent conical ring guide positioning structures 3. The multiple conical ring guide positioning structures 3 and the multiple copper tube concentric limiting support structures 4 are concentrically set.

[0047] S2, Positioning Conical Ring 1: Position the conical ring 1 from top to bottom into the conical ring guide positioning structure 3, and clamp the conical ring 1;

[0048] S3, positioning copper tube concentric limiting support structure 4: the copper tube concentric limiting support structure 4 includes a sliding seat 41, a copper tube limiting component 42 placed on the sliding seat 41, and a locking component 43 that presses the copper tube limiting component 42 against the outer wall of the cone ring 1; a conformal rope 5 is glued to the position of the copper tube limiting component 42 near the outer wall of the cone ring 1, and multiple copper tube limiting components 42 move toward the outer wall of the cone ring 1;

[0049] S4. Fixing the copper tube limiting assembly 42 and the cone ring 1: The locking assembly 43 presses the copper tube limiting assembly 42 against the outer wall of the cone ring 1. (Refer to...) Figure 6 The screw 6 is passed through the copper tube limiting assembly 42 into the cone ring 1 and locked and fixed by the nut 7. Polyester felt 8 is glued around the nut 7. The polyester felt 8 is filled with an insulating plate 9. Let it stand for 12-18 hours.

[0050] S5. Install connecting copper pipe 2: A buffer polyester felt 10 is glued at the contact position between the copper pipe limiting component 42 and the connecting copper pipe 2. Each connecting copper pipe 2 is horizontally embedded in the corresponding copper pipe limiting component 42. Fiberglass tape 11 impregnated with epoxy resin is selected and tied to the corresponding copper pipe limiting component 42 by cross binding. Multiple connecting copper pipes 2 are staggered from top to bottom on the outer circumference of the cone ring 1 and form a ring structure, thus completing the installation of the connecting copper pipe 2 of the cone ring 1 at the motor end.

[0051] S6. Remove the clamping of the locking assembly 43 on the copper tube limiting assembly 42 and the conical ring guide positioning structure 3 on the conical ring 1, and lift the conical ring with the connecting copper tube off the concentric installation device as a whole.

[0052] In this invention, when installing the motor end conical ring 1 and the connecting copper tube 2, the conical ring 1 is first hoisted onto multiple conical ring guide positioning structures 3. Since the conical ring guide structure 3 and the multiple copper tube concentric limiting support structures 4 are concentrically set, the conical ring 1 is positioned and clamped on the conical ring guide positioning structure 3. The copper tube limiting component 42 that positions the connecting copper tube 2 is fixed on the sliding seat 41 under the clamping force of the locking component 43. It moves towards the conical ring 1 on the sliding seat 41, realizing the synchronous concentric movement of multiple copper tube concentric limiting support structures 4 towards the conical ring 1. This ensures the concentricity of the conical ring 1 and the multiple connecting copper tubes 2, eliminating the need for manual measurement and marking, quickly achieving installation concentricity, greatly improving installation efficiency, and effectively ensuring the uniformity of the subsequent current distribution of the large motor and the mechanical stability of the connecting copper tubes.

[0053] In this embodiment, the concentric installation device also includes an annular base 12, and multiple conical ring guide positioning structures 3 and multiple copper tube concentric limiting support structures 4 are arranged on the annular base 12 at equal circumference intervals, and the multiple conical ring guide positioning structures 3, multiple copper tube concentric limiting support structures 4, and annular base 12 are arranged concentrically.

[0054] Based on this embodiment, refer to Figure 3 , Figure 4 The copper tube limiting assembly 42 includes two fiberglass limiting blocks 421 disposed on the sliding seat 41. The fiberglass limiting blocks 421 on the sliding seat 41 are evenly spaced and circumferentially distributed and concentrically arranged with the annular base 12. The end face of the fiberglass limiting block 421 near the conical ring 1 has multiple grooves 422 for embedding conformal ropes 5. The outer end face of the fiberglass limiting block 421 away from the conical ring 1 has multiple limiting grooves 423 for embedding copper tubes 2. The multiple limiting grooves 423 on each fiberglass limiting block 421 are distributed sequentially from top to bottom. The fiberglass limiting block 421 has a threaded hole 424 for a screw 6 to pass through. The 21 has a rectangular through hole 425 for accommodating the nut 7 and polyester felt 8. The rectangular through hole 425 is connected to the threaded hole 424. The glass fiber limiting block 421 has multiple strap through holes 426 evenly distributed vertically. Each limiting groove 423 has two strap through holes 426 on its rear side, and the front edge of the strap through hole 426 on the upper side has a strap through hole 427. The extension direction of the strap through hole 426 and the strap through hole 427 is consistent with the extension direction of the limiting groove 423. The glass fiber tape 11 cross-binds the connecting copper tube 2 embedded in the limiting groove 423 through two corresponding strap through holes 426 and one corresponding strap through hole 427.

[0055] This invention replaces the original bakelite bracket connecting the copper tube 2 and the conical ring 1 with a fiberglass retaining block. The fiberglass retaining block 421 and the conical ring 1 are fixed by a screw 6 and a nut 7. The fiberglass retaining block 421 and the connecting copper tube 2 are then bound and fixed by a resin-impregnated fiberglass tape 11. The screw 6 ensures tight contact between the connecting copper tube 2 and the conical ring 1 through pre-tightening force, reducing contact resistance and preventing motor overheating. The screw 6 provides rigid fixation to prevent displacement of the connecting copper tube 2 and the conical ring 1 under large vibrations or impacts. The fiberglass tape 11 evenly distributes the surface pressure of the connecting copper tube 2, preventing local stress concentration in the screw 6 from causing deformation or cracks.

[0056] Compared to traditional bakelite supports, the glass fiber limiting block 421 in this invention has high mechanical strength and high heat resistance. It is not prone to microcracks under long-term alternating stress, making it suitable for the high-frequency vibration environment of high-speed motors. Glass fiber has a low moisture absorption rate, and its insulation performance deteriorates more slowly in humid environments, avoiding the insulation degradation problem caused by moisture absorption in bakelite supports. Moreover, it is suitable for environments with high current-induced temperature rise, reducing the risk of thermal deformation and mitigating the problem of uneven contact stress caused by thermal expansion and contraction.

[0057] Therefore, in this invention, when the conical ring 1 and the connecting copper pipe 2 are installed, a concentric installation device with a specific structure is used to replace the traditional bakelite bracket. A special fixing method is adopted, which uses screws 6 and glue-impregnated glass fiber tape 11 to quickly achieve installation concentricity, avoid loosening of the connection due to mechanical impact or thermal expansion and contraction, reduce contact resistance, and prevent the motor from overheating and aging.

[0058] In this embodiment, the binding method of the glass fiber tape in step S5 is as follows: Figure 5 The specific steps include,

[0059] S51. After the epoxy resin-impregnated glass fiber tape 11 is cured, it is passed through the upper binding through hole 426 and binding through hole 427, wrapped 3-5 layers in the circumferential direction and then cut to form a wrapped base layer. The beginning and end ends of the glass fiber tape 11 are embedded in the bottom of the base layer.

[0060] S52. Pull the fiberglass tape 11 from the upper binding hole 426 through the connecting copper tube 2 toward the opposite end of the lower binding hole 426, pass through the lower binding hole 426, and then through the connecting copper tube 2 toward the opposite end of the upper binding hole 426. An X-shaped binding track is formed on the outer end face of the connecting copper tube 2. After 3-5 layers of cyclic wrapping, cut it to form a wrapping binding layer. The beginning and end sections of the fiberglass tape 11 are embedded at the bottom of the wrapping binding layer.

[0061] In this invention, a base layer is first formed by the glass fiber tape 11, and then the copper tube 2 and the glass fiber limiting block 421 are connected by cross binding. This binding method has the following technical advantages:

[0062] 1. The base layer improves the binding adhesion. When the fiberglass tape 11 is directly bound to the smooth surface of the connecting copper tube or the fiberglass limiting block 421, the fiberglass tape 11 is prone to slippage. However, the base layer increases the friction coefficient, ensuring the positioning accuracy of subsequent cross binding. Secondly, the base layer acts as a buffer layer, which can evenly distribute the binding pressure of the fiberglass tape 11, avoid deformation of the connecting copper tube 2, and prevent the fiberglass tape 11 from breaking due to stress concentration at the edge under long-term vibration.

[0063] 2. The mesh structure formed by cross binding can suppress radial vibration and prevent the connecting copper tube 2 from separating from the glass fiber limiting block 421. Furthermore, the elastic distribution of cross binding can better absorb the high-frequency vibration energy during operation, reducing the risk of fatigue fracture.

[0064] Based on this embodiment, the bottom of the glass fiber limiting block 421 has a slot 428, and the sliding seat 41 has a rib 429 that cooperates with the slot 428. The extending directions of the rib 429 and the slot 428 are consistent with the sliding direction of the sliding seat 41.

[0065] In this application, the slot 428 at the bottom of the glass fiber limiting block 421 cooperates with the protrusion 429 on the sliding seat 41 to ensure the perpendicularity of the glass fiber limiting block 421 and the cone ring 1 during the sliding process of the sliding seat 41, thereby achieving the concentricity of multiple glass fiber limiting blocks 421 and multiple cone ring guiding and positioning structures.

[0066] Based on this embodiment, the locking assembly 43 includes two U-shaped blocks 431 disposed on the sliding seat 41. The outer end of the U-shaped block 431 has a horizontal fixing block 4311. The horizontal fixing block 4311 is fixed to the sliding seat 41 by bolts. The two U-shaped blocks 431 respectively cover the lower front end position of the two glass fiber limiting blocks 421 on the sliding seat 41. There is a stop block 432 disposed between the two U-shaped blocks 431 and the two glass fiber limiting blocks 421. The locking assembly 43 also includes clamping blocks 433 disposed on both sides of the two glass fiber limiting blocks 421. The two clamping blocks 433 can move towards each other or backwards through synchronous clamping members, thereby clamping or releasing the two glass fiber limiting blocks 421.

[0067] During the sliding process, in order to further ensure the positional accuracy of the glass fiber limiting block 421 on the sliding seat 41 and to avoid the glass fiber limiting block 421 from being misaligned during the sliding process and affecting the concentricity of the installation, a locking assembly 43 is provided on the sliding seat 41. The two clamping blocks 433 of the locking assembly 43 move towards each other or away from each other under the action of the synchronous clamping member, so as to quickly clamp or release the glass fiber limiting block 421. The setting of the locking assembly 43 not only ensures the positional accuracy of the glass fiber limiting block 421 during the sliding, but also provides an effective clamping force for the subsequent binding of the glass fiber tape 11 to the connecting copper tube 2, so as to avoid the positional deviation of the glass fiber limiting block 421 during binding.

[0068] Based on this embodiment, refer to Figure 7 , Figure 8 The synchronous clamping component includes a drive cavity 434 disposed within a sliding seat 41. The bottom of the drive cavity 434 has an electric push rod 435. A connecting plate 436 extends vertically from the lower end of the clamping block 433 toward the drive cavity 434. A swing plate 437 is movably connected to the bottom of the drive cavity 434. The center of the swing plate 437 is movably connected to the bottom of the drive cavity 434. The driving end of the electric push rod 435 is movably connected to the end of the swing plate 437. A connecting rod 438 is movably connected between the connecting plate 436 and the swing plate 437. The two connecting rods 438 are respectively disposed on either side of the center of the swing plate 437. When the electric push rod 435 extends or retracts, it drives the swing plate 437 to reciprocate around its center point, thereby causing the two connecting rods 438 to pull the corresponding clamping blocks 433 to move in opposite directions or in opposite directions.

[0069] The synchronous clamping component in this application can drive two clamping blocks 433 to contract or expand synchronously. When contracting, it ensures that both sides of the two clamping blocks 433 are subjected to a uniform and stable clamping force.

[0070] Based on this embodiment, the lower end of the clamping block 433 has a slider 439, and the sliding seat 41 has a slide rail 4310 connected to the slider 439. The extension direction of the slide rail 4310 is perpendicular to the movement direction of the glass fiber limiting block 421.

[0071] The slider 439 can be manually slid and squeezed by the operator, or it can be locked on the sliding seat 41 by means of screw or lead screw transmission. The specific structure of the sliding is not limited here.

[0072] Based on this embodiment, the conical ring guide positioning assembly 3 includes an outer clamping seat 31 disposed on the annular base 12, an inner clamping seat 32 on the inner side of the outer clamping seat 31, a space 33 between the inner clamping seat 32 and the outer clamping seat 31 for longitudinally embedding the conical ring 1, an electric push rod 34 between the inner clamping seat 32 and the annular base 12, the driving end of the electric push rod 34 being connected to the inner clamping seat 32, the inner clamping seat 32 being disposed on the inner side of the conical ring 1, and the outer clamping seat 31 being disposed on the outer side of the conical ring 1, the inner clamping seat 32 clamping or releasing the conical ring 1 under the extension and retraction action of the electric push rod 34.

[0073] Based on this embodiment, refer to Figure 9 The inner wall of the outer card holder 31 that contacts the cone ring 1 includes a guide arc surface 35 and an inclined contact surface 36 from top to bottom. The inner wall of the inner card holder 32 that contacts the cone ring 1 includes a guide arc surface 37 and an inclined contact surface 38 from top to bottom. The top of the outer card holder 31 is higher than the top of the inner card holder 32.

[0074] During installation, the electric push rod 34 is in a retracted state, the inner clamp 32 is far away from the outer clamp 31, and the space 33 between the inner clamp 32 and the outer clamp 31 is relatively large. Due to the large size of the cone ring 1 of the large motor, during the installation process, the cone ring 1 is hoisted from top to bottom into the multiple cone ring guide positioning structures 3. When the cone ring 1 approaches the multiple outer clamps 31, the cone ring 1 slides down under the guidance of the guide arc surface 35 and moves into contact with the inclined contact surface 36 until the bottom of the cone ring 1 is flush with the bottom of the inclined contact surface 36. At this time, the electric push rod 34 is lifted, so that the inclined contact surface 38 of the inner clamp 32 is in contact with the inner wall of the cone ring 1, thereby quickly realizing the concentric installation of the cone ring 1 and the multiple cone ring guide positioning structures 3, providing a basic guarantee for the subsequent positioning of the copper pipe 2.
