Fig. 1 is a schematic structural diagram of a clamping device according to an embodiment of the present application, as shown in fig. 1, in an embodiment, the clamping device includes a magnetic force adjusting mechanism a and a clamping jaw mechanism B. Wherein the clamping jaw mechanism B is arranged on the magnetic force adjusting mechanism A and comprises a magnetic pressing piece 5. It should be noted that the magnetic force adjusting mechanism a provides a magnetic force to attract the magnetic pressing member 5 to move and press the product, so that the clamping jaw mechanism B can clamp the product. Further, the jaw mechanism B also comprises a support seat 6. Specifically, the supporting seat 6 is fixedly arranged on the casing 1 and is used for bearing the product to be clamped. Simultaneously, the magnetic pressing piece 5 is movably arranged on the supporting seat 6, so that the magnetic pressing piece can move relative to the supporting seat 6 under the magnetic force action of the magnetic force adjusting mechanism A, and further the product can be clamped by being matched with the supporting seat 6. Optionally, the bottom of the magnetic pressing member 5 is provided with grooves and/or holes to avoid parts of the product that cannot be gripped. It should be noted that the jaw mechanism B may be replaced according to the structure of different products, so that the magnetic pressing member 5 can be matched with the products.
Fig. 2 is a schematic structural view of a magnetic force adjusting mechanism provided by the embodiment of the present application, fig. 3 is a schematic structural view of another view of the magnetic force adjusting mechanism provided by the embodiment of the present application, and in combination with fig. 2 and fig. 3, in one embodiment, the magnetic force adjusting mechanism a includes a housing 1, a magnetic attraction component 2, and a partition component 3. Wherein, the magnetism part 2 and the partition part 3 are arranged on the shell 1, and a screw hole is reserved at the bottom of the shell 1 so as to be arranged at a preset position. Further, fig. 4 is a schematic cross-sectional view of a magnetic force adjusting mechanism provided by the embodiment of the present application, and fig. 5 is a schematic structural view of a magnetic attraction component provided by the embodiment of the present application, and as shown in fig. 4 and fig. 5, the magnetic attraction component 2 includes an adjusting magnet 21, where the magnetic pole distribution of the adjusting magnet 21 is the same as that of the magnetic pressing piece 5. Illustratively, the adjusting magnet 21 has an upper end of N pole and a lower end of S pole; the upper end of the magnetic pressing piece 5 is an N pole, and the lower end is an S pole. That is, the regulating magnet 21 can provide an attractive force to the magnetic pressing piece 5, so that the magnetic pressing piece 5 can be attracted to move and press the product. It will be readily appreciated that moving the adjustment magnet 21 toward the magnetic pressing piece 5 increases the attractive force to the magnetic pressing piece 5, and moving the adjustment magnet 21 away from the magnetic pressing piece 5 decreases the attractive force to the magnetic pressing piece 5. Therefore, the magnetic force adjusting mechanism A can control the attractive force to the magnetic pressing piece 5 through the magnetic attraction component 2, so that the clamping force of the clamping jaw mechanism B to products can be controlled, and proper clamping force can be selected for different products.
Fig. 6 is a schematic structural view of a partition member according to an embodiment of the present application, and the partition member 3 includes a first partition magnet 31 and a second partition magnet 32 as shown in fig. 4 and 6. Wherein the first blocking magnet 31 is adjacent to the adjusting magnet 21 and has the same magnetic pole distribution as the adjusting magnet 21, and the second blocking magnet 32 is adjacent to the magnetic pressing piece 5 and has the opposite magnetic pole distribution as the adjusting magnet 21. Illustratively, the first blocking magnet 31 has an upper end of N pole and a lower end of S pole; the second blocking magnet 32 has an upper end of an S pole and a lower end of an N pole. That is, when the first and second blocking magnets 31 and 32 are moved between the regulating magnet 21 and the magnetic pressing piece 5, that is, to the first position, the second blocking magnet 32 is homopolar-opposed to the magnetic pressing piece 5, so that the attraction force of the regulating magnet 21 to the magnetic pressing piece 5 can be blocked by the repulsive force to open the jaw mechanism B and take and put the product. Correspondingly, when the first and second blocking magnets 31, 32 are moved away from the first position, the adjusting magnet 21 attracts the magnetic pressing member 5 to move and press the product. The attractive force between the first blocking magnet 31 and the adjusting magnet 21 helps to move the first blocking magnet 31 and the second blocking magnet 32 to the first position, so that the repulsive force between the magnets is prevented from affecting the movement. Therefore, the magnetic force adjusting mechanism A can control the existence of attractive force to the magnetic pressing piece 5 through the partition component 3, so that the clamping force of the clamping jaw mechanism B to a product can be controlled, and the product can be taken and placed.
As shown in fig. 4, in one embodiment, the magnetically attractable component 2 further includes an adjustment drive assembly 22. It should be noted that the adjustment drive assembly 22 is movably provided on the housing 1 and is configured to drive the adjustment magnet 21 to move toward or away from the magnetic pressing piece 5. Specifically, when it is necessary to increase the attractive force of the adjustment magnet 21 to the magnetic pressing piece 5, the adjustment magnet 21 can be moved toward the magnetic pressing piece 5 by the adjustment drive assembly 22. Correspondingly, when it is desired to reduce the attraction force of the adjustment magnet 21 to the magnetic pressing piece 5, the adjustment magnet 21 can be moved away from the magnetic pressing piece 5 by the adjustment drive assembly 22. Therefore, the magnetic attraction component 2 can move the adjusting magnet 21 according to the product requirement by adjusting the driving component 22, so as to control the clamping force of the clamping jaw mechanism B on the product.
As shown in fig. 5, in one embodiment, the adjustment drive assembly 22 includes a first link 221 and a first slider 222. Wherein the first connection member 221 is provided in a rod shape and one end is connected to the adjustment magnet 21. Further, a first slider 222 is slidably provided on the housing 1, and is connected to the other end of the first connection member 221. Thus, when the first slider 222 slides on the housing 1, the adjusting magnet 21 can be moved by the first connection member 221. That is, the control of the amount of clamping force of the jaw mechanism B is achieved by moving the first slider 222 so as to apply a suitable clamping force to the product.
As shown in fig. 2, in one embodiment, a first slide rail 11 is provided on the housing 1 along a first direction X. In the present embodiment, the first direction X is a vertical direction. As an alternative embodiment, the first direction X may be set to be a horizontal direction or any other direction depending on the arrangement of the jaw mechanism B. Further, the first slider 222 is slidably disposed on the housing 1 through the first sliding rail 11. Therefore, the first sliding rail 11 can guide and bear the sliding of the first sliding block 222, so that the first sliding block 222 can be ensured to drive the adjusting magnet 21 to move more accurately, and the clamping force with the required size can be adjusted.
As shown in fig. 5, in one embodiment, the first slider 222 includes a first slider body 2221 and a first abutment 2222. Wherein, the first slider body 2221 is connected to the first connection member 221. Further, as shown in fig. 5, the adjustment drive assembly 22 further includes a first movable member 223 and a first drive member 224. Specifically, the first movable member 223 passes through the first slider body 2221, and both ends are connected to the first abutment member 2222 and the first driving member 224, respectively. That is, the first driving member 224 can make the first abutting member 2222 abut against or be away from the side wall of the first sliding rail 11 by moving the first movable member 223. Therefore, when the first driving member 224 drives the first movable member 223 to move towards the side wall of the first sliding rail 11, the first abutting member 2222 can be driven to move towards the side wall of the first sliding rail 11 until the first abutting member 2222 abuts against the side wall of the first sliding rail 11 to lock the first sliding block 222, so that the adjusting magnet 21 can be fixed at the current position when the required clamping force is obtained. Correspondingly, when the first driving member 224 drives the first movable member 223 to move away from the side wall of the first sliding rail 11, the first abutting member 2222 can be driven to be separated from the side wall of the first sliding rail 11, so that the locking of the first slider 222 can be released, and the first slider 222 can be moved to drive the adjusting magnet 21 to move and adjust the clamping force of the clamping jaw mechanism B.
As shown in fig. 2, in one embodiment, the side walls of the first slide rail 11 are disposed obliquely. It should be noted that the first slide rail 11 is a convex rail formed by protruding the surface of the housing 1 along the first direction X, and two side walls of the first slide rail 11 are disposed obliquely. Further, as shown in fig. 5, the first abutting piece 2222 and the first sliding rail 11 are matched with each other, that is, a side of the first abutting piece 2222 facing the first sliding rail 11 is configured as an inclined surface structure, so that the first abutting piece 2222 abuts against a side wall of the first sliding rail 11. Further, as shown in fig. 5, the first slider body 2221 includes a first connection portion 22211, and a first sliding portion 22212 and a first receiving portion 22213 formed by extending both ends of the first connection portion 22211 toward the housing 1. Specifically, the first connection portion 22211 is connected to the first connector 221, and the first sliding portion 22212 and the first sliding rail 11 are matched with each other, that is, a side of the first sliding portion 22212 facing the first sliding rail 11 is configured as an inclined surface, so that the first sliding portion 22212 is attached to a side wall of the first sliding rail 11. On the other hand, the first movable member 223 is disposed through the first receiving portion 22213, that is, the first receiving portion 22213 performs a receiving function on the first movable member 223, so that the first movable member 223 moves and drives the first abutting member 2222.
Alternatively, the first movable member 223 is provided in a rod-like structure, and one end is provided with a screw thread. Correspondingly, threaded holes are provided on the first receiving portion 22213 and the first abutting piece 2222 to mate with the first movable piece 223. On the other hand, the first driving member 224 is a rotary handle, and the first driving member 224 is provided with a receiving hole so as to be disposed at the unthreaded end of the first movable member 223 by over-fitting. Thus, the first movable member 223 may be driven to move by rotating the first driving member 224.
As shown in fig. 4, in one embodiment, there are two adjusting magnets 21, and the magnetic poles of the two adjusting magnets 21 are equally distributed, so that a larger attraction force can be provided to the magnetic pressing piece 5. Correspondingly, as shown in fig. 4, there are two adjustment drive assemblies 22, and the two adjustment drive assemblies 22 are respectively connected to one adjustment magnet 21. Therefore, the two adjusting driving assemblies 22 move the adjusting magnets 21 which are respectively connected, so that the adjusting magnets 21 have a larger adjusting range on the attractive force of the magnetic pressing piece 5, the attractive force can be adjusted more conveniently, and the clamping force with the required size can be obtained. The number of the adjustment magnets 21 and the adjustment driving units 22 may be set as needed, and is not limited thereto.
As shown in fig. 3, in one embodiment, the partition member 3 further includes a partition driving assembly 33. The blocking drive assembly 33 is movably disposed on the housing 1 and is configured to drive the first blocking magnet 31 and the second blocking magnet 32 to move to or from the first position. Specifically, when it is necessary to shut off the attractive force of the adjustment magnet 21 to the magnetic pressing piece 5, the first shut off magnet 31 and the second shut off magnet 32 can be moved to the first position by the shut off driving assembly 33. Correspondingly, when it is desired to restore the attraction of the adjustment magnet 21 to the magnetic pressing piece 5, the first and second blocking magnets 31, 32 may be driven away from the first position by the blocking drive assembly 33. Thereby, the blocking member 3 can move the first blocking magnet 31 and the second blocking magnet 32 by blocking the driving assembly 33 to control the clamping force of the clamping jaw mechanism B on the product so as to take and put the product.
As shown in connection with fig. 4 and 6, in one embodiment, the partition drive assembly 33 includes a second link 331 and a second slider 332. Wherein the second connection member 331 is provided in a rod shape, and one end is connected to the first and second blocking magnets 31 and 32. Alternatively, the first and second blocking magnets 31 and 32 are connected to the second connector 331 by welding. Specifically, the first blocking magnet 31 is homopolar opposed to the second blocking magnet 32, and the first blocking magnet 31 is disposed at the lower side of the second link 331, and the second blocking magnet 32 is disposed at the upper side of the second link 331. Further, a second slider 332 is slidably provided on the housing 1, and is connected to the other end of the second connector 331. Alternatively, the second slider 332 is connected to the second connector 331 by a fixing bolt. Thus, when the second slider 332 slides on the housing 1, the first blocking magnet 31 and the second blocking magnet 32 can be driven to move by the second connector 331.

Further, as shown in fig. 8, the top end of the stopper 412 is formed in an arc surface and is provided with a stopper groove 4121, the stopper groove 4121 being located on a side away from the notch of the guide groove 14. Thus, when the adjustment driving assembly 22 drives the adjustment magnet 21 to enter the guide groove 14 from the notch of the guide groove 14, the adjustment magnet 21 contacts with the cambered surface of the stop portion 412 and moves relatively, so that the third movable member 41 is forced to retract, so that the adjustment magnet 21 is arranged in the guide groove 14. On the other hand, the stopper groove 4121 serves to block the regulating magnet 21 from falling out of the guide groove 14. It will be readily appreciated that the housing 1 is provided with through holes which match the third movable member 41 so that the third movable member 41 moves through the housing 1. The first blocking magnet 31 and the second blocking magnet 32 are provided with avoiding grooves matching with the stopper 412, so as to avoid collision between the first blocking magnet 31 and the second blocking magnet 32 and the stopper 412.
