[0002] Mechanical automation refers to the process in which a machine or device automatically operates or controls according to a predetermined program or instruction without human intervention. Mechanical automation is the process in which a machine or device realizes automatic control through mechanical means. The realization of mechanical automation has led mechanical production to a new field. Through the automatic control system, it has truly achieved large-scale industrial production and reduced labor intensity, and improved labor efficiency. In industrial production, people often use grasping devices to mechanically and automatically grasp objects to improve work efficiency.

[0003] However, the common mechanical automated grasping devices on the market still have some obvious deficiencies in design and use. First, the grasping parts in these devices are often difficult to remove and replace, which means that when objects of different shapes or sizes need to be grasped, personnel cannot easily replace suitable grasping parts, which greatly limits the versatility of the grasping devices. Secondly, these common mechanical automated grasping devices often lack buffer structures. In the process of grasping objects, the objects are easily damaged by excessive clamping force.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model provides a mechanical automatic grasping device, such as Figure 1-3As shown, the mechanical automated grasping device comprises: a box body 1, wherein two strip holes are provided at the bottom of the box body 1; a double-axis motor 2 fixedly mounted on the inner wall of the bottom of the box body 1, wherein screws 3 are fixedly mounted on the two output shafts of the double-axis motor 2; two sliders 4 respectively threadedly mounted on the two screws 3, wherein the two sliders 4 are respectively slidably connected to the inner walls of the two strip holes; two mounting blocks 5 respectively welded on the two sliders 4, wherein mounting grooves are provided on the two mounting blocks 5; and two grasping mechanisms respectively mounted on the two mounting blocks 5 for clamping objects.

[0021] In this embodiment, when the mechanical automated grasping device is used, the dual-axis motor 2 is started, and the dual-axis motor 2 will drive the two screws 3 to rotate, and the two screws 3 will drive the two sliders 4 to approach each other, and the two sliders 4 will drive the two mounting blocks 5 to approach each other, so that the two grasping mechanisms can clamp the objects, and the grasping is more convenient. Since a buffer spring 8 is provided in the grasping mechanism, the grasping member 10 on the grasping mechanism can be well buffered, so that the grasped objects will not be damaged due to excessive clamping force. When objects of other shapes or sizes need to be grasped, in order to ensure the stability of clamping, it is only necessary to gently pull the pull rod 11 on the grasping mechanism, so that the personnel can remove and replace the grasping member 10 on the grasping mechanism conveniently, and it is convenient for personnel to replace the appropriate grasping member 10 to clamp the corresponding objects, which can improve the versatility of the device and achieve better use effect.

[0022] In a further preferred embodiment of the utility model, the grabbing mechanism includes: a plurality of sliding rods 6 slidably mounted on the mounting block 5, one end of the plurality of sliding rods 6 being fixedly mounted with the same shell 7, the shell 7 being adapted to the mounting slot, and a slot being provided on one side of the shell 7; a plurality of buffer springs 8 being fixedly mounted on the inner wall of one side of the mounting slot, one side of the plurality of buffer springs 8 being fixedly connected to the shell 7; a positioning block 9 slidably mounted on the slot, a grabbing piece 10 being fixedly mounted on one side of the positioning block 9, and a slot being provided on the bottom of the positioning block 9; a pull rod 11 slidably mounted on the shell 7; a reset spring 12 slidably sleeved on the pull rod 11; a baffle 13 welded on the pull rod 11, a clamping block 14 being welded on the baffle 13, and the clamping block 14 being adapted to the slot.

[0023] In this embodiment, the grabbing mechanism is used to clamp objects. When in use, the dual-axis motor 2 will drive the screw 3 to rotate, the screw 3 will drive the slider 4 to move, the slider 4 will drive the mounting block 5 to move, the mounting block 5 will drive the shell 7 to move through the slide bar 6 and the buffer spring 8, the shell 7 will drive the positioning block 9 and the grabbing member 10 to move, so that the grabbing member 10 can clamp or release objects. When the grabbing member 10 clamps the object, if the clamping force is too large, the shell 7 will cause a certain amount of compression on the buffer spring 8, and also cause the slide bar 6 to slide on the mounting block 5 to a certain extent, so that the grabbing member 10 will not cause damage to the object due to the excessive clamping force applied. When replacing, pull the pull rod 11 down, the pull rod 11 will drive the baffle 13 to squeeze the reset spring 12, and the baffle 13 will also drive the card block 14 to disengage from the slot of the positioning block 9. After the card block 14 is out of the slot, the positioning block 9 can be pulled out from the slot of the shell 7, so that the removal of the grasping member 10 can be completed, and then the positioning blocks 9 on other grasping members 10 can be inserted into the slot, and then the pull rod 11 is released, and then the reset spring 12 will automatically reset the baffle 13, and the baffle 13 will drive the card block 14 to reset, so that the card block 14 is inserted into the slot of the positioning block 9, so that the replacement operation of the grasping member 10 is completed, and the replacement is convenient and labor-saving.
