Description

Technical Field

[0001] The invention belongs to the technical field of magnetic protection structures, and in particular relates to a coreless magnetic spring vertical lifting structure. Background Art

[0002] The lifting structure is divided into: electric slide, pneumatic slide; according to the transmission method, it is divided into: ball screw slide, synchronous belt slide, rack slide, which are commonly used in the processing and manufacturing field.

[0003] Existing lifting structures are mostly used for clamping and moving products for secondary processing, and are used to help workers do some repetitive and multiple tasks. However, the mechanism is driven by electricity. Once there is a problem with the circuit or a sudden power outage, the mechanism equipment will lose stress, without protective components, and fall instantly, which can easily cause the mechanism to damage the product and cause certain damage to the mechanism itself. Moreover, it is difficult for the clamping assembly of the lifting structure to protect the product while clamping. The clamping assembly is usually driven by a cylinder to move the clamping block. Once the clamping force is large, it will cause damage to the product itself. Once the clamping force is small, it is difficult to stably clamp the product, making it easy for the product to fall from the clamping assembly. The strength needs to be debugged by the staff many times, which is very cumbersome and energy-consuming. At the same time, the clamping assembly at the bottom of the lifting structure has no protective structure. Once a problem occurs in the circuit, the clamping assembly loses power control, and the clamping force of the clamping assembly on the product will lose and expand to both sides. At this time, the product loses its clamping force and will separate from the clamping assembly and fall, causing damage to the product and is likely to injure the staff, posing certain safety hazards. For this reason, we propose a coreless magnetic spring vertical lifting structure. Summary of the invention

[0014] Preferably, the tension between the magnetic spring body and the magnetic material column is greater than or equal to the load of the product clamped by the clamping protection mechanism.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The magnetic spring body of the present invention can play a protective role, preventing the lifting structure from falling instantly and damaging the product or even the equipment in the event of a power outage or other sudden situation. For example, the pulling force of the magnetic spring body is 25 Newtons. In the no-load state, the structure connected to the magnetic spring body will automatically rebound to the upper limit position and block the magnetic material column. After a load of 25 Newtons is installed on the magnetic spring body, the mover can stay arbitrarily within the height of the magnetic material column, that is, it is in a suspended state. No matter where the load object on the magnetic spring body is pushed, it will be suspended and stopped steadily regardless of gravity without falling. When the linear motor is running, if the power is suddenly cut off, the magnetic spring body and the structure on the first magnetic spring seat will suddenly stop, and will not suddenly fall and damage the product and equipment. Therefore, the magnetic spring body provides very safe protection for the linear motor.

[0016] By setting up the clamping protection mechanism, a protective effect is achieved. The inner sides of the first clamping outer column and the second clamping outer column are provided with clamping inner columns, and the clamping inner columns can play a role in redundant clamping of the product. When the first clamping outer column and the second clamping outer column clamp the product, the clamping inner columns and the clamping triangle blocks are in contact with both sides of the product. At this time, when force continues to be applied to clamp the product, the clamping inner column will move toward the direction of the first clamping outer column and the second clamping outer column, and the push spring will contract under the force, providing redundant space for the product and reducing the situation where the product is directly damaged by a large force.

[0017] The protection mechanism further improves the safety of the clamping protection mechanism. Since the clamping of the first clamping outer column and the second clamping outer column is achieved through the meshing connection of the first clamping gear and the second clamping gear, the clamping effect is generated. After the first clamping outer column and the second clamping outer column clamp the product, the protection mechanism will be operated to move the first protection plate and the second protection plate to the tooth grooves of the first clamping gear and the second clamping gear, so that the first clamping gear and the second clamping gear cannot continue to rotate, thereby achieving a protection effect. Even if a short circuit problem occurs at this time, the first clamping outer column and the second clamping outer column will only clamp the product in the middle, which is very stable and reduces the risk of the product falling.

[0018] At the same time, the measuring gear can be used to record and measure the moving height of the first magnetic spring seat and the clamping protection mechanism. When the first magnetic spring seat and the clamping protection mechanism drive the product to move up and down, the measuring gear is meshed and connected with the measuring tooth column. The number of revolutions of the measuring gear is recorded, and the moving height of the first magnetic spring seat and the clamping protection mechanism is known. In addition, the measuring gear has a small rotation resistance in the measuring column shell, and is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 12 The present invention provides a technical solution: a coreless magnetic spring vertical lifting structure, comprising a linear motor 100, a second magnetic spring seat 105 is provided at the end of the linear motor 100, and further comprising: The magnetic material column 103 is symmetrically arranged between the two second magnetic spring seats 105; The first magnetic spring seat 101 is disposed on one side of the linear motor 100 , and the first magnetic spring seat 101 is sleeved on the outside of the magnetic material column 103 ; The displacement adjustment mechanism 300 is connected to the ends of the two first magnetic spring seats 101 and moves along with the movement of the first magnetic spring seats 101; The clamping protection mechanism 200 is arranged at the bottom of the displacement adjustment mechanism 300; The protection mechanism 500 is disposed on the clamping protection mechanism 200 and is used to protect the clamping protection mechanism 200 .

[0022] The magnetic spring body 106 of the present invention can play a protective role, preventing the lifting structure from falling instantly and damaging the product or even the equipment in the event of a power outage or other sudden situation. For example, the pulling force of the magnetic spring body 106 is 25 Newtons. In the no-load state, the structure connected to the magnetic spring body 106 will automatically rebound to the upper limit position and block the magnetic material column 103. After the 25 Newton load is installed on the magnetic spring body 106, the mover can stay at any height within the height of the magnetic material column 103, that is, it is in a suspended state. No matter where the load object on the magnetic spring body 106 is pushed, it will be suspended and stopped steadily regardless of gravity and will not fall. When the linear motor 100 is running, if the power is suddenly cut off, the magnetic spring body 106 and the structure on the first magnetic spring seat 101 will suddenly stop, and will not suddenly fall and damage products and equipment. Therefore, the magnetic spring body 106 has a very safe protective effect on the linear motor 100.

[0023] In this embodiment, preferably, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The bottom of the linear motor 100 is provided with an equipment base 102, the middle of the second magnetic spring seat 105 is provided with a limiting vertical plate 104, the middle of the first magnetic spring seat 101 is provided with a limiting slider 107 near the limiting vertical plate 104, and the limiting slider 107 is used in conjunction with the limiting vertical plate 104; A magnetic spring body 106 is provided at the middle of the first magnetic spring seat 101 where the magnetic material column 103 is sleeved, and the magnetic spring body 106 and the magnetic material column 103 are used in magnetic cooperation, and the two are arranged at the same center.

[0024] The magnetic spring body 106 is located inside the first magnetic spring seat 101 to provide protection. The magnetic spring body 106 and the magnetic material column 103 form a magnetic spring structure. When the magnetic spring body 106 is pushed, the magnetic spring body 106 moves on the magnetic material column 103. Once the force is lost, the magnetic spring body 106 will move like Figure 5At this time, assuming that the pulling force of the magnetic spring body 106 is 25 Newtons, the first magnetic spring seat 101 and the clamping protection mechanism 200 on the outside of the magnetic spring body 106 can also be loaded with 25 Newtons, and the magnetic spring body 106 can achieve the effect of stopping as you go. For example, if the magnetic spring body 106 is pushed to the middle position of the magnetic material column 103, the magnetic spring body 106, the first magnetic spring seat 101, and the clamping protection mechanism 200 will stop steadily at the middle position of the magnetic material column 103. After the magnetic spring body 106 loses its force, it will not return to its original position, but will hover.

[0025] In this embodiment, preferably, Figure 1 , Figure 2 , Figure 3 , Fig. 9 , Fig.10 , Fig.11 The clamping protection mechanism 200 includes a first clamping outer column 201 and a second clamping outer column 202. The middle parts of the first clamping outer column 201 and the second clamping outer column 202 are both provided with a clamping inner column 207. The ends of the clamping inner column 207 are both provided with a clamping triangle block 206. The clamping triangle block 206 is rotatably connected to the first clamping outer column 201 through a first linkage shaft 205. The ends of the clamping inner column 207 away from the clamping triangle block 206 are both provided with a second linkage shaft 212. The end of the first clamping outer column 201 away from the clamping triangle block 206 is rotatably connected to the first clamping gear 203 via the third linkage shaft 211 , and the end of the second clamping outer column 202 away from the clamping triangle block 206 is rotatably connected to the second clamping gear 204 via the third linkage shaft 211 .

[0026] When the first clamping gear 203 and the second clamping gear 204 rotate, they respectively drive the first clamping outer column 201 and the second clamping outer column 202 to rotate, so that the two move in opposite directions at the same time, thus achieving a clamping effect, and the two clamping inner columns 207 can achieve a redundant protection effect.

[0027] By setting the clamping protection mechanism 200, a protective effect is achieved. The inner sides of the first clamping outer column 201 and the second clamping outer column 202 are both provided with a clamping inner column 207, and the clamping inner column 207 can play a role in redundant clamping of the product. When the first clamping outer column 201 and the second clamping outer column 202 clamp the product, the clamping inner column 207 and the clamping triangle block 206 are in contact with both sides of the product. At this time, when the force continues to be applied to clamp the product, the clamping inner column 207 will move toward the direction of the first clamping outer column 201 and the second clamping outer column 202, and the push spring 209 will be forced to contract, providing redundant space for the product and reducing the situation where the product is directly damaged by a large force.

[0028] In this embodiment, preferably, Figure 1 , Figure 2 , Figure 3 , Fig. 9 , Fig.10 , Fig.11 A clamping pad 210 is provided parallel to the surface of the clamping inner column 207, and a pushing rod 208 is provided on one side surface of the clamping pad 210. The pushing rod 208 passes through the clamping inner column 207 and the first clamping outer column 201 respectively, and a pushing spring 209 is provided on the part of the pushing rod 208 located between the first clamping outer column 201 and the clamping inner column 207.

[0029] The clamping pad 210 can increase the friction force. The clamping pad 210 and the clamping inner column 207 are parallel to each other. When the clamping inner column 207 comes into contact with the product, the clamping pad 210 can increase the friction force, making the clamping of the clamping protection mechanism 200 more stable.

[0030] The clamping inner column 207 has a redundant effect because the clamping inner column 207 can be rotatably connected to the first clamping outer column 201 through the first linkage shaft 205, so that after the first clamping outer column 201 and the second clamping outer column 202 clamp the product, the clamping inner column 207 can also change its displacement. At the same time, a push spring 209 is provided between the clamping inner column 207 and the clamping inner column 207, and the push spring 209 can restore the deformation.

[0031] In this embodiment, preferably, Figure 1 , Figure 2 , Figure 3 , Fig. 9 , Fig.10 , Fig.11 The clamping protection mechanism 200 is a symmetrical structure. When the first clamping gear 203 and the second clamping gear 204 are meshed with each other, the first clamping outer column 201 and the second clamping outer column 202 located on both sides of the first clamping gear 203 and the second clamping gear 204 will move in opposite directions at the same time, and the protection mechanism 500 is located directly above the first clamping gear 203 and the second clamping gear 204.

[0032] When the first clamping gear 203 or the second clamping gear 204 rotates, it will drive the other to rotate through the meshing connection, so that the first clamping gear 203 and the second clamping gear 204 rotate at the same time, and the first clamping outer column 201 and the second clamping outer column 202 move at the same time.

[0033] In this embodiment, preferably, Fig. 9 , Fig.10 The push rod 208 is a cylindrical structure, and a rectangular groove for use with the push rod 208 is opened in the middle of the first clamping outer column 201, while the position of the clamping pad 210 is changed.

[0034] The rectangular groove has a limiting effect on the push rod 208, so that the push rod 208 can only move horizontally and will not separate from the first clamping outer column 201, and the width of the rectangular groove is greater than the diameter of the push rod 208. This is because when the push rod 208 changes its displacement with the clamping inner column 207, the moving trajectory of the push rod 208 is not a straight line. The width of the rectangular groove is wider and can adapt to the moving trajectory of the push rod 208.

[0035] In this embodiment, preferably, Fig. 9 , Fig.10 , Fig.11 , Fig.12 The protection mechanism 500 includes a protection connecting plate 501, and a first protection plate 503 and a second protection plate 504 are symmetrically arranged on both sides of the protection connecting plate 501, and the two are arranged in parallel. A protection inner groove 505 is formed in the middle of the first protection plate 503 and the second protection plate 504, and a height adjustment column 502 is arranged on the top of the protection connecting plate 501, and the first protection plate 503 and the second protection plate 504 move up and down through the height adjustment column 502; The width of the protective inner groove 505 is greater than the thickness of the teeth of the second clamping gear 204 , and the thickness of the first protective plate 503 is less than the width of the tooth groove of the second clamping gear 204 .

[0036] The protection mechanism 500 further improves the safety of the clamping protection mechanism 200. Since the clamping of the first clamping outer column 201 and the second clamping outer column 202 is achieved through the meshing connection of the first clamping gear 203 and the second clamping gear 204, the clamping effect is generated. After the first clamping outer column 201 and the second clamping outer column 202 clamp the product, the protection mechanism 500 is operated to move the first protection plate 503 and the second protection plate 504 to the tooth grooves of the first clamping gear 203 and the second clamping gear 204, so that the first clamping gear 203 and the second clamping gear 204 cannot continue to rotate, thereby achieving a protection effect. Even if a short circuit problem occurs at this time, the first clamping outer column 201 and the second clamping outer column 202 will only clamp the product in the middle, which is very stable and reduces the risk of the product falling.

[0037] When the first clamping gear 203 and the second clamping gear 204 have completed their rotation and the first clamping outer column 201 has clamped the product, the first protective plate 503 is immediately dropped through the height adjustment column 502 to engage the first clamping gear 203 and the second clamping gear 204. Only when the first clamping outer column 201 has moved to the required position will the first protective plate 503 be moved to the original position, loosening the first clamping outer column 201 so that the product falls. The entire process is automated and quick to use, which improves safety without affecting the normal operation of the work.

[0038] In this embodiment, preferably, Figure 1 , Figure 2 , Figure 3 The displacement adjustment mechanism 300 includes a T-shaped seat 301, the T-shaped seat 301 is connected to the two first magnetic spring seats 101, a displacement adjustment rod 302 is provided at the bottom of the T-shaped seat 301, a horizontal plate 303 is provided at the bottom of the displacement adjustment rod 302, the horizontal plate 303 is movably connected to a drive motor housing 305 through two angle connection side plates 304, and the drive motor housing 305 is connected to the clamping protection mechanism 200; The ends of the two angle-connected side plates 304 are rotatably connected to the drive motor housing 305 . A rotary motor 306 is provided at the end of the angle-connected side plates 304 close to the drive motor housing 305 . When the two rotary motors 306 are running at the same time, the drive motor housing 305 is driven to rotate.

[0039] The displacement adjustment mechanism 300 can be used for height adjustment and rotation adjustment of the clamping protection mechanism 200. When the clamping protection mechanism 200 needs to change the clamping angle, it only needs to operate the rotary motor 306, so that the two rotary motors 306 operate and drive the output shaft to rotate, and the drive motor housing 305 rotates between the two angle connection side plates 304, thereby changing the angle of the clamping protection mechanism 200. Figure 1 is the parallel angle between the clamping protection mechanism 200 and the device base 102, Figure 2 It is the vertical angle between the clamping protection mechanism 200 and the equipment base 102.

[0040] In this embodiment, preferably, the distance measuring structure 400 includes a measuring plate 403, which is arranged on the limiting vertical plate 104, and a plurality of measuring gear columns 402 are arranged on the surface of the measuring plate 403. A measuring column shell 401 is provided on the first magnetic spring seat 101, and a measuring gear 404 is arranged in the measuring column shell 401. A through groove is provided on one side of the measuring column shell 401 close to the measuring gear column 402, for meshing and connecting the measuring gear 404 with the measuring gear column 402.

[0041] At the same time, the moving height of the first magnetic spring seat 101 and the clamping protection mechanism 200 can be recorded and measured by the measuring gear 404. When the first magnetic spring seat 101 and the clamping protection mechanism 200 drive the product to move up and down, the measuring gear 404 is meshed and connected with the measuring tooth column 402. The number of revolutions of the measuring gear 404 is recorded, and the moving height of the first magnetic spring seat 101 and the clamping protection mechanism 200 is known. In addition, the measuring gear 404 has a small rotation resistance in the measuring column housing 401, and is more convenient to use.

[0042] In this embodiment, preferably, the pulling force between the magnetic spring body 106 and the magnetic material column 103 is greater than or equal to the load of the product clamped by the clamping protection mechanism 200 .

[0043] When the pulling force between the magnetic spring body 106 and the magnetic material column 103 is greater than or equal to the load of the product clamped by the clamping protection mechanism 200, the clamping protection mechanism 200 and the product clamped by the clamping protection mechanism 200 can be suspended on the magnetic material column 103, and even if the power is cut off at this time, the clamping protection mechanism 200 and the product clamped by the clamping protection mechanism 200 will not fall, and they will remain in a suspended state; once the pulling force between the magnetic spring body 106 and the magnetic material column 103 is less than the load of the product clamped by the clamping protection mechanism 200, the protection effect will not be achieved, and the magnetic spring body 106 can only play a role in buffering the descent.

[0044] Working principle and use process: The size of the magnetic spring body 106 is set according to the weight of the product, so that the tension between the magnetic spring body 106 and the magnetic material column 103 is greater than or equal to the load of the product clamped by the clamping protection mechanism 200. For example, the tension of the magnetic spring body 106 is 25 Newtons. In the no-load state, the structure connected to the magnetic spring body 106 will automatically rebound to the upper limit position and block on the magnetic material column 103. After the load of 25 Newtons is installed on the magnetic spring body 106, the mover can The magnetic material column 103 can stay anywhere within the height, that is, it is in a suspended state. No matter where the load object on the magnetic spring body 106 is pushed, it will be suspended steadily without falling down despite the gravity. When the linear motor 100 is running, if the power is suddenly cut off, the magnetic spring body 106 and the structure on the first magnetic spring seat 101 will suddenly stop, and will not suddenly fall down and damage the product and equipment. Therefore, the magnetic spring body 106 plays a very safe protective effect on the linear motor 100. When the first clamping outer column 201 and the second clamping outer column 202 are needed to clamp the product, it is only necessary to operate the first clamping gear 203 or the second clamping gear 204. Since the two are meshed and connected, the rotation of one will drive the rotation of the other. The first clamping gear 203 and the second clamping gear 204 will drive the first clamping outer column 201 and the second clamping outer column 202 to move, so that the two move in opposite directions at the same time, that is, the clamping effect is achieved, and the two clamping inner columns 207 can play a redundant protection effect. The first clamping outer column 201 and the second clamping outer column The inner side of each of the first and second clamping outer columns 201 and 202 is provided with a clamping inner column 207, and the clamping inner column 207 can play a role in the redundant clamping of the product. When the first clamping outer column 201 and the second clamping outer column 202 clamp the product, the clamping inner column 207 and the clamping triangle block 206 are in contact with both sides of the product. At this time, when the force continues to be applied to clamp the product, the clamping inner column 207 will move toward the direction of the first clamping outer column 201 and the second clamping outer column 202, and the push spring 209 will be contracted by the force, which provides redundant space for the product and reduces the situation where the product is directly damaged by a large force. When the first clamping gear 203 and the second clamping gear 204 have completed their rotation and the first clamping outer column 201 has clamped the product, the first protection plate 503 is immediately dropped through the height adjustment column 502 to engage the first clamping gear 203 and the second clamping gear 204, so that the first clamping gear 203 and the second clamping gear 204 cannot continue to rotate. For details, please refer to Fig.11 Only when the first clamping outer column 201 moves to the required position will the first protective plate 503 be moved to the original position, loosening the first clamping outer column 201, so that the product falls. The whole process is automated and quick to use, which improves safety without affecting the normal operation of the work. Even if a short circuit occurs at this time, the first clamping outer column 201 and the second clamping outer column 202 will only clamp the product in the middle, which is very stable and reduces the risk of product falling.
