Description

Technical Field

[0001] This utility model relates to a splitter suitable for a horizontal winding machine for motor stators, belonging to the field of motor manufacturing technology. Background Technology

[0002] A winding machine is a mechanical production equipment for embedding coils into the iron core of an electric motor. Most existing motor stator winding machines are vertical or horizontal.

[0003] For example, patent application No. 202411387725.0 discloses a horizontal winding machine for a motor stator, including a winding machine body, two clamping arms on the right side of the winding machine body, a winding module located between the two clamping arms on the right side of the winding machine body, two support frames on the right side of the winding machine body, a slide rail on the top of each of the two support frames, a support base on the bottom of both the winding machine body and the support frames, and a support mechanism that is slidably connected to the slide rail between the tops of the two support frames.

[0004] Although the aforementioned patent can achieve the function of motor processing, the current technology is not comprehensive and has the following drawbacks: When the inner push support cylinder is inserted into the wire mold of the horizontal winding machine for motor stator, the inner push support cylinder can support the wire mold guide bar of the horizontal winding machine for motor stator. After the inner push support cylinder is pushed into place, the lack of protective function causes high-frequency hard collisions between the wire mold guide bar and the connecting plate, which accelerates the wear of the contact surface material and shortens the service life of key components such as the wire mold guide bar of the horizontal winding machine for motor stator.

[0005] To solve one of the above problems, there is an urgent need for a splitting mechanism suitable for horizontal winding machines for motor stators. Utility Model Content

[0006] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to avoid direct contact and wear between the wire mold guide strip and the connecting plate by adding a protective rubber ring, thereby extending the service life of the wire mold guide strip. To this end, a splitting head suitable for a horizontal winding machine for motor stator is provided.

[0007] The present invention relates to a splitting head for a horizontal winding machine for motor stators, comprising a hollow inner push support cylinder. The outer surface of the inner push support cylinder is provided with multiple sets of sliding grooves that cooperate with the wire mold guide strips. The sliding grooves are aligned with the length direction of the inner push support cylinder. The multiple sets of sliding grooves are arranged around the center line of the inner push support cylinder, and the included angle between adjacent grooves is equal. A convex ridge is formed between adjacent sliding grooves. The inner push support cylinder is characterized by having a transition connecting shaft connected to one end, and the other end of the transition connecting shaft being detachably connected to a connecting plate. A handle is coaxially provided on the back of the connecting plate, and a protective rubber ring is detachably installed on the transition connecting shaft.

[0008] In use, the operator holds the handle and pushes the inner support cylinder into the wire mold of the horizontal winding machine for the motor stator. After the inner support cylinder is inserted into the wire mold, it supports the wire mold guide bar. After the inner support cylinder is pushed in, the wire mold guide bar will abut against the side of the protective rubber ring. The transition connecting shaft ensures the insertion depth of the inner support cylinder. At the same time, the protective rubber ring prevents direct contact and wear between the wire mold guide bar and the connecting plate, extending the service life of the wire mold guide bar.

[0009] The inner support cylinder has a hollow structure, which reduces the weight of the split head and makes it easier for the operator to use.

[0010] Preferably, a connecting ring is provided inside the tail end of the inward-pushing support cylinder, dividing the interior of the inward-pushing support cylinder into a front cavity and a rear cavity. An internally inserted support column is embedded in the front cavity. The front end of the transition connecting shaft is inserted into the rear cavity. The other end of the transition connecting shaft is provided with a rear end that mates with a protective rubber ring. The protective rubber ring is fitted onto the rear end end, and the length of the rear end end is equal to the thickness of the protective rubber ring. The connecting plate is a disc, and the outer diameter of the protective rubber ring is equal to the outer diameter of the connecting plate. The diameter of the circle containing the bottom of the slide groove is greater than the inner diameter of the protective rubber ring but smaller than the outer diameter of the protective rubber ring. This ensures that the tail end of the wire mold guide can abut against the protective rubber ring, preventing the wire mold guide from colliding and wearing with the connecting plate. The internally inserted support column and the transition connecting shaft are non-metallic, which ensures the support effect while minimizing product weight.

[0011] Preferably, it also includes a connecting bolt, one end of which has a nut that abuts against the connecting plate. The threaded section of the connecting bolt passes sequentially through a first through hole in the connecting plate, a second through hole in the transition connecting shaft, and a third through hole on the connecting ring before connecting to a threaded hole on the inner support column. This is a detachable structure, facilitating the installation and fixing of the protective rubber ring 8.

[0012] Preferably, the connecting bolts are provided in two sets, which are arranged around the center line of the transition connecting shaft and the included angle between adjacent sets is 180 degrees. This ensures a reliable connection.

[0013] Preferably, the inner support cylinder and the connecting ring are integrally formed and are made of copper.

[0014] Preferably, both the insert support column and the transition connecting shaft are made of polytetrafluoroethylene rods.

[0015] Preferably, the connecting plate is provided with an outer sheath, and the handle, connecting plate and outer sheath are integrally formed and are all made of aluminum alloy.

[0016] Preferably, one end of the internal support column extends out of the front cavity to form an impact head, and a buffer rubber pad is provided on the impact head. When the push rod of the horizontal winding machine for the motor stator is ejected, the push rod moves within the cavity surrounded by multiple sets of wire mold guides and will first touch the buffer rubber pad on the impact head, which can avoid direct contact and wear between the push rod and the impact head, thus extending the service life of the push rod.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention relates to a splitter for a horizontal winding machine for motor stators. When the inner push support cylinder is inserted into the wire mold of the horizontal winding machine for motor stators, the inner push support cylinder can support the wire mold guide bar of the horizontal winding machine for motor stators. After the inner push support cylinder is pushed into place, the wire mold guide bar will abut against the side of the protective rubber ring. The setting of the transition connecting shaft can ensure the pushing depth of the inner push support cylinder. At the same time, the setting of the protective rubber ring can avoid direct contact and wear between the wire mold guide bar and the connecting plate, thus extending the service life of the wire mold guide bar.

[0019] The splitter described in this utility model is suitable for horizontal winding machines for motor stators. The inner push support cylinder has a hollow structure, which reduces the weight of the splitter and makes it easier for the operator to use.

[0020] The splitter of the present invention, applicable to the horizontal winding machine for motor stator, has internal support columns and transition connecting shafts made of polytetrafluoroethylene rods, which can ensure the support effect and reduce the weight of the product as much as possible.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0029] Example 1, as Figure 1-2 As shown, the splitting head suitable for a horizontal winding machine for motor stators includes a hollow inner push support cylinder 1. The outer surface of the inner push support cylinder 1 is provided with multiple sets of sliding grooves 2 that cooperate with the wire mold guide strips. The sliding grooves 2 are aligned with the length direction of the inner push support cylinder 1. The multiple sets of sliding grooves 2 are arranged around the center line of the inner push support cylinder 1, and the included angle between adjacent sliding grooves is equal. A convex ridge is formed between adjacent sliding grooves 2. One end of the inner push support cylinder 1 is connected to a transition connecting shaft 5. The other end of the transition connecting shaft 5 is detachably connected to a connecting plate 10. A handle 9 is coaxially provided on the back of the connecting plate 10. A protective rubber ring 8 is detachably installed on the transition connecting shaft 5.

[0030] In use, the operator holds the handle 9 and pushes the inner support cylinder 1 into the wire mold of the horizontal winding machine for the motor stator. After the inner support cylinder 1 is inserted into the wire mold of the horizontal winding machine for the motor stator, the inner support cylinder 1 can support the wire mold guide bar of the horizontal winding machine for the motor stator. After the inner support cylinder 1 is pushed into place, the wire mold guide bar will abut against the side of the protective rubber ring 8. The setting of the transition connecting shaft 5 can ensure the pushing depth of the inner support cylinder 1. At the same time, the setting of the protective rubber ring 8 can avoid direct contact and wear between the wire mold guide bar and the connecting plate 10, thus extending the service life of the wire mold guide bar.

[0031] The inner support cylinder 1 has a hollow structure, which reduces the weight of the split head and makes it easier for the operator to use.

[0032] Example 2, as Figure 1-2As shown, the splitting head suitable for a horizontal winding machine for motor stators includes a hollow inner push support cylinder 1. The outer surface of the inner push support cylinder 1 is provided with multiple sets of sliding grooves 2 that cooperate with the wire mold guide strips. The sliding grooves 2 are aligned with the length direction of the inner push support cylinder 1. The multiple sets of sliding grooves 2 are arranged around the center line of the inner push support cylinder 1, and the included angle between adjacent sliding grooves is equal. A convex ridge is formed between adjacent sliding grooves 2. One end of the inner push support cylinder 1 is connected to a transition connecting shaft 5. The other end of the transition connecting shaft 5 is detachably connected to a connecting plate 10. A handle 9 is coaxially provided on the back of the connecting plate 10. A protective rubber ring 8 is detachably installed on the transition connecting shaft 5.

[0033] Furthermore, referring to Figure 3-5 The inner support cylinder 1 has a connecting ring 3 inside its tail end, which divides the inner part of the inner support cylinder 1 into a front cavity and a rear cavity. An inner support column 4 is embedded in the front cavity. The front end of the transition connecting shaft 5 has a front end head 7 inserted into the rear cavity. The other end of the transition connecting shaft 5 has a rear end head 6 that mates with a protective rubber ring 8. The protective rubber ring 8 is fitted onto the rear end head 6, and the length of the rear end head 6 is equal to the thickness of the protective rubber ring 8. The connecting plate 10 is a disc. The outer diameter of the protective rubber ring 8 is equal to the outer diameter of the connecting plate 10. The diameter of the circle containing the bottom of the groove 2 is greater than the inner diameter of the protective rubber ring 8 but less than its outer diameter. This ensures that the tail end of the wire mold guide can abut against the protective rubber ring 8, preventing the wire mold guide from colliding and wearing with the connecting plate 10. The inner support column 4 and the transition connecting shaft 5 are non-metallic, ensuring support while minimizing product weight.

[0034] Furthermore, it also includes a connecting bolt 12, one end of which has a nut that abuts against the connecting plate 10. The threaded section of the connecting bolt 12 passes sequentially through the first through hole 13 of the connecting plate 10, the second through hole 14 of the transition connecting shaft 5, and the third through hole 15 on the connecting ring 3 before connecting to the threaded hole 16 on the inner support column 4. This is a detachable structure, facilitating the installation and fixing of the protective rubber ring 8.

[0035] Furthermore, the connecting bolts 12 are provided in two sets, which are arranged around the center line of the transition connecting shaft 5 and the included angle between adjacent sets is 180 degrees. The connection is reliable.

[0036] Furthermore, the inner support cylinder 1 and the connecting ring 3 are integrally formed and are made of copper.

[0037] Furthermore, both the inserted support column 4 and the transition connecting shaft 5 are made of polytetrafluoroethylene rods.

[0038] Furthermore, the connecting plate 10 is provided with an outer sheath 11, and the handle 9, the connecting plate 10, and the outer sheath 11 are integrally formed and are all made of aluminum alloy.

[0039] Furthermore, one end of the internal support column 4 extends out of the front cavity to form an impact head 17, and a buffer rubber pad 18 is provided on the impact head 17. When the push rod of the horizontal winding machine for the motor stator is ejected, the push rod moves within the cavity surrounded by multiple sets of wire mold guide bars and will first touch the buffer rubber pad 18 on the impact head 17, which can avoid direct contact and wear between the push rod and the impact head 17, and extend the service life of the push rod.

[0040] The present invention relates to a splitter for a horizontal winding machine for motor stators. When the inner push support cylinder is inserted into the wire mold of the horizontal winding machine for motor stators, the inner push support cylinder can support the wire mold guide bar of the horizontal winding machine for motor stators.
