An electromagnetic coil assembly tooling

Abstract

The present invention belongs to the technical field of coil assembly, and discloses an electromagnetic coil assembly tooling, which includes a support bottom plate and a support base. On both sides of the top of the support bottom plate, there are fixedly connected limiting long blocks. The outer surface of the limiting long blocks is movably connected with a concave platform plate. At the rear end of the inner cavity of the concave platform plate, there is fixedly connected a first spring piece. Through the cooperation among structures such as a T-shaped long block, an outer sleeve rod, an inner rod, and a positive T-shaped block, the device has a good protective effect on operators. By the operator first holding the handle on the T-shaped long block and pulling the T-shaped long block outward, the T-shaped long block drives the concave platform plate to move outward. When the T-shaped long block drives the concave platform plate out from directly below the limiting plate, at this time, the positive T-shaped block is located below both sides of the limiting plate, thus preventing the situation that the limiting plate suddenly drops and causes harm to the operator's hand.

Description

Technical Field

[0001] The present invention relates to the technical field of coil assembly, and specifically to a tooling for electromagnetic coil assembly. Background Technique

[0002] Electromagnetic coils are established by utilizing the magnetic field existing around a wire. Winding it into a spiral shape strengthens the magnetic field, that is, achieving the highest magnetic field intensity with the smallest space. Using a wire with a layer of insulating paint on the surface instead of an ordinary wire is also for saving space. Currently, common electromagnetic coils are divided into toroidal coils and square iron-core coils. The role of adding an iron core to the coil is to increase the magnetic field intensity. The iron core concentrates all the magnetic field lines around the coil and conducts them through the iron core. Removing the iron core will reduce the magnetic induction between the coils.

[0003] Currently, when people assemble a square iron-core coil, they often align the square frame wound with the coil with the E-shaped iron core, making the opening of the E-shaped iron core face upwards. At the same time, the middle hollow part of the square is sleeved on the middle part of the E-shaped iron core. Subsequently, the iron chip punch is moved downward, so that the iron chip punch punches the iron core sleeved in the middle part of the square frame, thereby causing an iron core punching mark on the iron core sleeved in the middle part of the square frame. However, since the existing one moves the iron chip punch downward through an electric hydraulic rod, after the punching is completed, the operator needs to manually replace the electromagnetic coil after punching. At this time, if the operator does not timely turn off the electric hydraulic rod, the electric hydraulic rod will push the iron chip punch downward, resulting in the situation that the device punches the operator's hand. Therefore, a tooling for electromagnetic coil assembly is proposed to solve the problems raised in the background technique. Summary of the Invention

Around the top of the limiting plate, there are fixedly connected second limiting vertical rods. The outer surface of the second limiting vertical rods is sleeved with a third elastic spring and a connecting top plate. In the middle of the inner cavity of the connecting top plate, there is movably connected an iron core stamping head.

[0008] Preferably, the front end of the first spring piece is fixedly connected with the limiting long block. The middle of the concave platform plate is concave. The T-shaped long block is located in the inner cavity of the supporting bottom plate, and the outer surface of the T-shaped long block is movably connected with the inner cavity of the supporting bottom plate. The front end of the T-shaped long block is in the shape of a handle.

[0009] Preferably, the front and rear ends of the longitudinal limiting rod are respectively fixedly connected with the front and rear ends of the inner cavity of the T-shaped long block. One end of the longitudinal limiting rod close to the T-shaped slider is fixedly connected with the T-shaped slider. The end of the first elastic spring far from the T-shaped slider is fixedly connected with the inner cavity of the supporting bottom plate.

[0010] Preferably, the movable distance of the part of the inner rod in the inner cavity of the second spring piece is one-half of the length of the inner rod itself. The end of the second spring piece far from the inner rod is fixedly connected with the inner cavity of the outer sleeve rod. One end of the inner rod close to the positive T-shaped block is hinged with the positive T-shaped block. The outer surface of the positive T-shaped block is movably connected with the inner cavity of the supporting bottom plate.

[0011] Preferably, the first inclined block cooperates with the second inclined block. The bottom of the inverted T-shaped block is located inside the inner cavity of the support bottom plate. The bottom of the inverted T-shaped block is in contact with the top of the support base. The long groove cooperates with the inverted T-shaped block.

[0012] Preferably, the outer surfaces at the four corners of the bottom of the support bottom plate are movably connected to the four corners of the inner cavity at the top of the support base. The top and bottom of the fourth elastic spring are respectively fixedly connected to the bottom of the support bottom plate and the top of the support base.

[0013] Preferably, the limiting plate is located below the support connecting plate. One end of the top of the second elastic spring is fixedly connected to the bottom of the limiting plate.

[0014] Preferably, the connecting top plate is located above the support connecting plate. The top and bottom of the third elastic spring are respectively fixedly connected to the bottom of the connecting top plate and the top of the support connecting plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the cooperation among structures such as the I-shaped long block, the outer sleeve rod, the inner rod, and the regular T-shaped block, the device has a good protective effect on the operator. By the operator first holding the handle on the I-shaped long block and pulling the I-shaped long block outward, the I-shaped long block drives the concave platform plate to move outward. At the same time, when the I-shaped long block moves outward, it also drives the I-shaped slider and the end of the outer sleeve rod close to the I-shaped slider to move outward. At this time, with the cooperation of the horizontal limiting rod and the limiting effect inside the support bottom plate, the end of the inner rod close to the regular T-shaped block drives the regular T-shaped block to move inward. After the I-shaped long block drives the concave platform plate to move out from directly below the limiting plate, at this time, the regular T-shaped block is located below both sides of the limiting plate, thus preventing the situation that the limiting plate suddenly drops and causes harm to the operator's hand.

[0016] Through the cooperation among structures such as the second inclined block, the long groove, the second elastic spring and the inverted T-shaped block, the whole device descends and the iron core punching head disengages from the contact with the electric pressure rod, thereby further enhancing the safety of the device during use. After the I-shaped long block drives the concave platform plate to move outward, at the same time, the I-shaped long block also drives the first inclined block to move towards the side close to the second inclined block. When the first inclined block cooperates with the second inclined block, the fourth elastic spring will be compressed at this time, thereby causing the whole supporting bottom plate to move downward. At the same time, since the regular T-shaped block moves towards the inner side, it will also drive the inverted T-shaped block to move towards the side close to the long groove. At this time, when the whole supporting bottom plate moves downward, the inverted T-shaped block will cooperate with the long groove. Finally, due to the overall descent of the supporting bottom plate, it will also drive the iron core punching head to move downward, thereby making the top of the iron core punching head disengage from the contact with the electric hydraulic rod.

Embodiment

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0028] As Figures 1 to 8 shown, the present invention provides an electromagnetic coil assembly tooling, including a support bottom plate 1 and a support base 15. Both sides of the top of the support bottom plate 1 are fixedly connected with limit long blocks 2. The outer surface of the limit long block 2 is movably connected with a concave platform plate 3. The rear end of the inner cavity of the concave platform plate 3 is fixedly connected with a first spring piece 4. The middle of the bottom of the support bottom plate 1 is fixedly connected with an I-shaped long block 5. The inner cavity of the I-shaped long block 5 is movably connected with an I-shaped slider 6. Both ends of the I-shaped slider 6 are hinged with an outer sleeve rod 7. The inner cavity of the outer sleeve rod 7 is movably connected with an inner rod 8. One end of the inner rod 8 close to the outer sleeve rod 7 is fixedly connected with a second spring piece 9. Both ends of the inner cavity of the support bottom plate 1 are movably connected with a transverse limit rod 10. The outer surface of the transverse limit rod 10 is movably connected with a positive T-shaped block 11. The inner cavity of the I-shaped slider 6 is movably connected with a longitudinal limit rod 12. The outer surface of the longitudinal limit rod 12 is sleeved with a first elastic spring 13. By the operator first holding the handle part on the I-shaped long block 5 and pulling the I-shaped long block 5 outward, the I-shaped long block 5 drives the concave platform plate 3 to move outward. At the same time, when the I-shaped long block 5 moves outward, it will also drive the I-shaped slider 6 and one end of the outer sleeve rod 7 close to the I-shaped slider 6 to move outward. At this time, with the cooperation of the transverse limit rod 10 and the limiting effect in the inner cavity of the support bottom plate 1, one end of the inner rod 8 close to the positive T-shaped block 11 drives the positive T-shaped block 11 to move inward. When the I-shaped long block 5 drives the concave platform plate 3 out of the directly below the limit plate 21, at this time, the positive T-shaped block 11 is located below both sides of the limit plate 21, thus preventing the situation that the limit plate 21 suddenly drops and causes harm to the operator's hand.

[0029] As Figure 1, Figure 5 , Figure 6 , Figure 7 As shown in Figure 5 , Figure 6 , and Figure 7 , a first inclined block 14 is fixedly connected to the rear end of the bottom of the I-shaped long block 5, a second inclined block 16 is fixedly connected to the front end of the middle of the top of the support base 15, the four corners of the outer surface of the bottom of the support base plate 1 are sleeved with fourth elastic springs 18, long grooves 17 are formed on both sides of the top of the support base plate 1, and an inverted T-shaped block 19 is fixedly connected to the bottom of the positive T-shaped block 11; after the I-shaped long block 5 drives the concave platform plate 3 to move outward, at the same time, the I-shaped long block 5 will also drive the first inclined block 14 to move toward the side close to the second inclined block 16. When the first inclined block 14 cooperates with the second inclined block 16, the fourth elastic spring 18 will be compressed at this time, so that the entire support base plate 1 moves downward. At the same time, since the positive T-shaped block 11 moves inward, it will drive the inverted T-shaped block 19 to move toward the side close to the long groove 17. At this time, when the entire support base plate 1 moves downward, the inverted T-shaped block 19 will cooperate with the long groove 17. Finally, due to the overall downward movement of the support base plate 1, the iron core punching head 26 will be driven to move downward, so that the top of the iron core punching head 26 is disengaged from the electric hydraulic rod.

[0030] As Figure 1 , Figure 5 , Figure 8 As shown in Figure 1 , Figure 5 , and Figure 8 , first limiting vertical rods 27 are fixedly connected to the front and rear ends of both sides of the top of the support base plate 1. The outer surfaces of the first limiting vertical rods 27 are movably connected with second elastic springs 20, limiting plates 21, and support connecting plates 22. Second limiting vertical rods 23 are fixedly connected to the four circumferences of the top of the limiting plates 21. The outer surfaces of the second limiting vertical rods 23 are sleeved with third elastic springs 24 and connecting top plates 25. The middle part of the inner cavity of the connecting top plate 25 is movably connected with an iron core punching head 26. The limiting plate 21 is located below the support connecting plate 22. One end of the top of the second elastic spring 20 is fixedly connected to the bottom of the limiting plate 21, and one end of the bottom of the second elastic spring 20 is fixedly connected to the first limiting vertical rod 27. A square opening is formed in the middle of the limiting plate 21, and the diameter of the square opening is larger than the diameter of the bottom of the iron core punching head 26. The connecting top plate 25 is located above the support connecting plate 22. The top and bottom of the third elastic spring 24 are respectively fixedly connected to the bottom of the connecting top plate 25 and the top of the support connecting plate 22; by pressing downward on the electric hydraulic rod, the iron core punching head 26 drives the connecting top plate 25 to move downward, and at this time, both the connecting top plate 25 and the first limiting vertical rod 27 will be compressed, so that the limiting plate 21 and the third elastic spring 24 move downward. Subsequently, the limiting plate 21 first contacts the coil and the square frame and presses and fixes them. Subsequently, the iron core punching head 26 continues to move downward and passes through the square opening, so as to realize punching the iron core located in the middle of the square frame and complete the operation;

[0031] It should be noted here that the electro-hydraulic rod is located directly above the iron core stamping head 26, and the bottom of the electro-hydraulic rod is in contact with the top of the iron core stamping head 26.

[0032] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 shown in the figure, the front end of the first spring piece 4 is fixedly connected to the limit long block 2. The middle part of the concave platform plate 3 is concave. The I-shaped long block 5 is located inside the cavity of the support bottom plate 1, and the outer surface of the I-shaped long block 5 is movably connected to the cavity of the support bottom plate 1. The front end of the I-shaped long block 5 is in the shape of a handle. The front and rear ends of the longitudinal limit rod 12 are respectively fixedly connected to the front and rear ends of the inner cavity of the I-shaped long block 5. One end of the longitudinal limit rod 12 close to the I-shaped slider 6 is fixedly connected to the I-shaped slider 6. One end of the first elastic spring 13 far from the I-shaped slider 6 is fixedly connected to the cavity of the support bottom plate 1. Through the design of the concave middle part of the concave platform plate 3, it is convenient to place the E-shaped iron core, and at the same time, it prevents the bottom of the iron core from being damaged when the device punches the electromagnet iron core. At the same time, the handle-shaped design of the I-shaped long block 5 enables the operator to hold the I-shaped long block 5 with one hand to prevent it from resetting when replacing the electromagnet iron core, and replace the iron core with the other hand. Such an operation avoids the problem that the operator's inattention may lead to dangerous situations.

[0033] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 shown in the figure, the movable distance of the part of the inner rod 8 in the inner cavity of the second spring piece 9 is one-half of the length of the inner rod 8 itself. One end of the second spring piece 9 far from the inner rod 8 is fixedly connected to the inner cavity of the outer sleeve rod 7. One end of the inner rod 8 close to the positive T-shaped block 11 is hinged to the positive T-shaped block 11. The outer surface of the positive T-shaped block 11 is movably connected to the inner cavity of the support bottom plate 1. By restricting the moving distance of the inner rod 8 inside the second spring piece 9, it is prevented that when the concave platform plate 3 moves out, the positive T-shaped block 11 is not at the bottom of the limit plate 21, which may lead to a reduction in the protection effect of the device.

[0034] As Figure 1 , Figure 5 , Figure 6 , Figure 7As shown, the first inclined block 14 cooperates with the second inclined block 16. The bottom of the inverted T-shaped block 19 is located inside the inner cavity of the support base plate 1. The bottom of the inverted T-shaped block 19 contacts the top of the support base 15. The long groove 17 cooperates with the inverted T-shaped block 19. The outer surfaces at the four corners of the bottom of the support base plate 1 are movably connected to the four corners of the inner cavity at the top of the support base 15. The top and bottom of the fourth elastic spring 18 are fixedly connected to the bottom of the support base plate 1 and the top of the support base 15 respectively. Through the design of the inverted T-shaped block 19, when the concave platform plate 3 is in the initial state directly below the limiting plate 21, at this time, the top and bottom of the inverted T-shaped block 19 will respectively contact the bottom of the support base plate 1 and the top of the support base 15, thereby providing sufficient support to the support base plate 1 and preventing the support base plate 1 from moving downward during subsequent stamping operations.

[0035] The working principle and usage process of the present invention are as follows:

[0036] First, the operator holds the handle on the I-shaped long block 5 and pulls the I-shaped long block 5 outward, causing the I-shaped long block 5 to drive the concave platform plate 3 to move outward. At the same time, when the I-shaped long block 5 moves outward, it will also drive the I-shaped slider 6 and the end of the outer sleeve rod 7 close to the I-shaped slider 6 to move outward. At this time, with the cooperation of the horizontal limiting rod 10 and the limiting effect inside the inner cavity of the support base plate 1, the end of the inner rod 8 close to the regular T-shaped block 11 drives the regular T-shaped block 11 to move inward. After the I-shaped long block 5 drives the concave platform plate 3 out from directly below the limiting plate 21, at this time, the regular T-shaped block 11 is located below both sides of the limiting plate 21, completing the operation.

[0037] After the I-shaped long block 5 drives the concave platform plate 3 to move outward, at the same time, the I-shaped long block 5 will also drive the first inclined block 14 to move toward the second inclined block 16. When the first inclined block 14 cooperates with the second inclined block 16, the fourth elastic spring 18 will be compressed at this time, causing the entire support base plate 1 to move downward. At the same time, since the regular T-shaped block 11 moves inward, it will also drive the inverted T-shaped block 19 to move toward the long groove 17. When the entire support base plate 1 moves downward at this time, the inverted T-shaped block 19 will cooperate with the long groove 17. Finally, due to the overall descent of the support base plate 1, it will drive the iron core stamping head 26 to move downward, causing the top of the iron core stamping head 26 to disengage from the electric hydraulic rod.
