[0035] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the utility model and do not constitute a limitation on the utility model.
[0036] like Figures 1 to 3 As shown, in order to achieve the above-mentioned purpose, the utility model proposes a clamping claw device, comprising:
[0037] A first rodless cylinder 11;
[0038] A slider mounting plate 20, a first end of which is connected to the sliding block of the first rodless cylinder 11, and moves up and down with the first rodless cylinder 11;
[0039] A horizontal fixing plate 30 connected to the second end of the slider mounting plate 20;
[0040] Two clamping assemblies are respectively connected to two sides of the horizontal fixing plate 30, and the two clamping assemblies can be moved closer to or farther from each other along the length direction of the horizontal fixing plate 30 to achieve clamping of the object to be clamped; and
[0041] The second rodless cylinder 12 is arranged in parallel with the first rodless cylinder 11, and the first end of the slider mounting plate 20 is connected to the second rodless cylinder 12. When the first rodless cylinder 11 descends, the second rodless cylinder 12 moves in the opposite direction to the first rodless cylinder 11 to reduce the descending speed of the first rodless cylinder 11.
[0042] Specifically, the first rodless cylinder 11 is composed of a cylinder barrel and a sliding block. The cylinder barrel is a hollow cylindrical structure, in which a piston and a seal are installed, and the lifting and lowering movement of the piston is controlled by the inflow and outflow of gas. The sliding block is a slidable component connected to the piston, and the slider mounting plate 20 is connected to the sliding block, thereby driving the slider mounting plate 20 to perform lifting and lowering movements.
[0043] The slider mounting plate 20 is a flat plate structure, and the first end of the slider mounting plate 20 is connected to the sliding block of the first rodless cylinder 11. The slider mounting plate 20 moves up and down through the lifting movement of the sliding block. The slider mounting plate 20 is used to carry the horizontal fixing plate 30.
[0044] The horizontal fixing plate 30 is another flat plate structure, and the horizontal fixing plate 30 is connected to the second end of the slider mounting plate 20. The horizontal fixing plate 30 is used to provide a fixed horizontal reference surface, wherein both clamping assemblies are mounted on the horizontal fixing plate 30, thereby facilitating the fixing of the clamping assemblies.
[0045] The clamping components are located on both sides of the horizontal fixing plate 30, and can be close to or far away from each other along the length direction of the horizontal fixing plate 30. The specific structure of the clamping components can be changed according to application requirements, and the clamping components can be clamping claws, clamps or clamps, etc. The clamping components are used to clamp the objects to be clamped to ensure that they will not fall.
[0046] The second rodless cylinder 12 is arranged in parallel with the first rodless cylinder 11, and the second rodless cylinder 12 is connected to the first end of the slider mounting plate 20. The function of the second rodless cylinder 12 is to reduce the descending speed of the first rodless cylinder 11 by moving in the opposite direction to the first rodless cylinder 11. This configuration can reduce the inertia and acceleration during the descending process, making the movement of the clamping device more stable and controllable.
[0047] By adopting the above technical solution, the entire clamping device structure is made more compact and simplified by using a rodless cylinder, reducing the space occupied by the traditional rod cylinder. The second rodless cylinder 12 moves in the opposite direction to the first rodless cylinder 11, reducing the speed of the first rodless cylinder 11 during the descent process, reducing the inertia and acceleration of the clamping device, making the movement smoother, and reducing the risk of shaking and damage to the object.
[0048] In one embodiment of the present application, a stop block 14 is provided on the sliding block of the first rodless cylinder 11 or the second rodless cylinder, and a buffer seat 13 matching with the stop block 14 is provided on one side of the first rodless cylinder 11 or the second rodless cylinder.
[0049] Specifically, the first rodless cylinder 11 is a pneumatic device, and its structure includes a cylinder barrel and a sliding block. A stop block 14 is provided on the sliding block to limit the range of motion of the sliding block. A buffer seat 13 that cooperates with the stop block 14 is provided on one side of the first rodless cylinder 11 to buffer the movement impact of the sliding block. The stop block 14 is connected to the sliding block. When the sliding block moves to a limited position, the stop block 14 contacts the buffer seat 13, and the movement of the sliding block on the first rodless cylinder 11 is reversely restricted, thereby limiting the position of the sliding block, facilitating the control of the movement position of the first rodless cylinder 11, and having a simple structure and being easy to implement.
[0050] By adopting the above technical solution, the addition of the stop block 14 and the buffer seat 13 makes the operation of the clamping device more precise and controllable.
[0051] In one embodiment of the present application, the clamping assembly comprises:
[0052] A guide rail 41 is arranged along the length direction of the horizontal fixing plate 30;
[0053] A fixed slider 42, slidably connected to the guide rail 41;
[0054] A driving member connected to the horizontal fixed plate 30 and used for driving the fixed slider 42 to reciprocate along the length direction of the guide rail 41; and
[0055] The chuck 51 is connected to the fixed slider 42 .
[0056] Specifically, the guide rail 41 is a linear structure, and the length direction of the guide rail 41 is consistent with the length direction of the horizontal fixed plate 30. The guide rail 41 and the horizontal fixed plate 30 are connected by a fixed connection method, such as welding, integral molding, etc. The guide rail 41 and the horizontal fixed plate 30 are connected by a fixed connection method, which can improve the connection strength between the guide rail 41 and the horizontal fixed plate 30 and improve the stability of the guide rail 41 during operation. Of course, according to the design requirements, the guide rail 41 and the horizontal fixed plate 30 can also be connected in a detachable manner, such as screw connection, bolt connection, etc. The guide rail 41 provides a smooth motion track, and the fixed slider 42 is clamped on the guide rail 41 and can reciprocate along the length direction of the guide rail 41.
[0057] The fixed slider 42 is a sliding member, which is slidably connected to the guide rail 41 and can reciprocate along the length direction of the guide rail. The driving member is connected to the horizontal fixed plate 30. The driving member can be a telescopic cylinder commonly used in the prior art, or a screw assembly composed of a stepping motor, a screw rod, a guide rod, and a nut. The driving assembly is used to drive the movement of the fixed slider 42.
[0058] The chuck 51 is a disc-shaped component, and the chuck 51 is connected to the fixed slider 42 .
[0059] The working process is as follows:
[0060] Before clamping the object to be clamped, the driving member drives the fixed slider 42 to approach the end of the horizontal fixed plate 30 to maintain the maximum spacing. At this time, the first rodless cylinder 11 drives the clamping plate 51 to move to both sides of the object to be clamped. At this time, the driving member drives the fixed slider 42 away from the end of the horizontal fixed plate 30 to clamp the object to be clamped. The process is simple and easy to implement.
[0061] By adopting the above technical solution, a smooth and precise motion track is provided through the setting of the guide rail 41 and the sliding connection of the fixed slider 42, so that the chuck 51 can accurately locate and clamp the object to be clamped. The use of the driving member enables the fixed slider 42 to reciprocate along the length direction of the guide rail 41, realizing efficient clamping and carrying operations. The setting of the guide rail 41 and the sliding connection of the fixed slider 42 provide a stable motion reference, ensuring the stability and accuracy of the chuck 51 during the movement.
[0062] In one embodiment of the present application, the driving member is a locked cylinder.
[0063] With the above technical solution, the locking cylinder is a combination of a cylinder and a mechanical locking mechanism, which can lock the piston of the cylinder in a specific position when necessary to prevent unintentional movement or sliding. The drive member is set as a locking cylinder, which can provide an additional safety measure. By locking the cylinder, the position of the fixed slider 42 can be fixed when necessary to prevent accidental sliding or loosening. This locking mechanism can ensure stability and safety during the movement and prevent unnecessary accidents.
[0064] In one embodiment of the present application, the clamping assembly further includes:
[0065] The pen cylinder 52 has a first end connected to the fixed slider 42 and a second end rotatably connected to the chuck 51 .
[0066] Specifically, the pen cylinder 52 is a telescopic cylinder, the first end of the pen cylinder 52 is connected to the fixed slider 42, and the second end of the pen cylinder 52 is rotatably connected to the chuck 51. The telescopic movement of the pen cylinder 52 can extend the position movement range of the chuck 51. By adjusting the air pressure and flow of the pen cylinder 52, the precise position control and adjustment of the chuck 51 can be achieved. This precise control can ensure that the chuck 51 accurately clamps and releases the object to be clamped, thereby improving the accuracy and consistency of the production process.
[0067] In one embodiment of the present application, at least two retractable limiting claws 53 are disposed on the chuck 51 , and each of the limiting claws 53 is connected to a driving rod 54 for driving the limiting claw 53 to extend or retract.
[0068] Specifically, at least two retractable limiting claws 53 are disposed on the chuck 51 , and each limiting claw 53 is connected to a driving rod 54 for driving the limiting claw 53 to move.
[0069] For ease of understanding, an example is given below:
[0070] When there are two limit claws 53, the two limit claws 53 are arranged opposite to each other, and the two limit claws 53 are connected to the chuck 51 through a snap ring, and the limit claws 53 can move on the surface of the chuck. The driving rod 54 is connected to the limit claws 53 to drive the limit claws 53 to extend or retract.
[0071] When there are four limiting claws 53 , the four limiting claws 53 are evenly distributed on the chuck 51 circumference, and the four driving rods 54 drive each limiting claw 53 to extend or retract.
[0072] By adopting the above technical solution, the chuck 51 can adapt to workpieces of different shapes and sizes through the retractable limit claw 53. The retractable movement of the limit claw 53 enables the chuck 51 to clamp and fix various parts of the workpiece, providing greater clamping flexibility and adaptability. At the same time, it also improves the stability of the clamped object.
[0073] In one embodiment of the present application, the clamping assembly further includes:
[0074] A rotating gear 55 is connected to a side of the chuck 51 away from the clamping surface;
[0075] The swing shaft 56 is connected to the rotating gear 55 and is used to drive the gear to rotate. The pen cylinder 52 is connected to the fisheye joint 57 on the swing shaft 56;
[0076] The driving rod 54 is provided with a long hole, and the limiting claw 53 is provided with a guide column. The guide column is arranged in the long hole and can reciprocate along the length direction of the long hole; the end of the driving rod 54 away from the limiting claw 53 is engaged with the gear and can rotate with the gear.
[0077] Specifically, the rotating gear 55 is a component connected to the side of the chuck 51 away from the clamping surface. The rotating gear 55 is a circular gear with a gear rack for transmitting a rotating force. The rotating gear 55 can rotate relative to the chuck 51.
[0078] The swing shaft 56 is a shaft connected to the rotating gear 55 and is used to drive the rotation of the gear. The swing shaft 56 is a long and thin shaft that enables the gear to rotate through the meshing of the gear.
[0079] The swing shaft 56 is provided with a fisheye joint 57, and the pen cylinder 52 is connected to the fisheye joint 57. The fisheye joint 57 is composed of a spherical head and a connecting rod, allowing rotation at different angles. The driving rod 54 is a component connected to the limit claw 53, and is provided with a long hole. The driving rod 54 is a long rod used to transmit force and control the movement of the limit claw 53.
[0080] The rotating gear 55 is connected to the side of the chuck 51 away from the clamping surface, and is connected to the chuck 51 through a bearing or other connecting parts. The swing shaft 56 is connected to the center of the rotating gear 55, and the pen cylinder 52 is connected to the fisheye joint 57 on the swing shaft 56, and is connected to the fisheye joint 57 through a connecting rod, so that the cylinder can control the rotation of the swing shaft 56, thereby driving the rotating gear 55 to rotate. The driving rod 54 is provided with a long hole, and the limiting claw 53 is provided with a guide column. The guide column is inserted into the long hole of the driving rod 54 and can reciprocate along the length direction of the long hole. The part of one end of the driving rod 54 away from the limiting claw 53 is meshed with the rotating gear 55. As the rotating gear 55 rotates, the driving rod 54 will be affected by the rotational force and produce corresponding movement. The synchronous extension or retraction of each limiting claw 53 is achieved to achieve the clamping of the object to be clamped.
[0081] By adopting the above technical solution, the rotation of the swing shaft 56 can be accurately controlled by combining the pen cylinder 52 and the fisheye joint 57. In this way, the precise position control and adjustment of the chuck 51 can be achieved to ensure the accuracy and stability of the clamped workpiece. Through the telescopic movement of the limit claw 53 and the connection between the drive rod 54 and the rotating gear 55, the chuck 51 has a flexible clamping ability. The position and telescopic degree of the limit claw 53 can be adjusted according to the shape and size of the workpiece to achieve the clamping and fixation of different workpieces.
[0082] In an embodiment of the present application, the number of the limiting claws 53 is four, and the four limiting claws 53 are evenly distributed around the chuck 51 .
[0083] With the above technical solution, since the four limiting claws 53 are evenly distributed around the chuck 51, a uniform clamping force can be provided, which helps to maintain the balance and stability of the workpiece and prevent the workpiece from deflecting or tilting.
[0084] In one embodiment of the present application, the first end of the pen cylinder 52 is hinged to the fixed slider 42 .
[0085] With the above technical solution, the first end of the pen cylinder 52 can move freely within a certain range through the hinged connection. This flexibility enables the pen cylinder 52 to adapt to work requirements at different positions and angles.
[0086] In one embodiment of the present application, a manual limiter for adjusting the initial position of the slider is further provided on one side of the guide rail 41 .
[0087] With the above technical solution, the manual limiter enables users to flexibly adjust the initial position of the slider according to specific needs and work requirements. This provides greater freedom and adaptability to meet the needs of different workpieces or operations.
[0088] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
