[0007] Furthermore, a first mounting rod is fixedly connected at the bottom of the first motor, a fixing flange is fixedly connected to the outer side of the first mounting rod, a connecting rod is fixedly connected to the inner side of the fixing flange, a clamping plate is fixedly connected to the inner side of the connecting rod, a connecting hole is opened on one side of the second gear, the connecting rod passes through the connecting hole, and the clamping plate is movably sleeved in the sleeve.

[0008] Furthermore, the gripping assembly includes a third mounting rod, the inner side of the third mounting rod is fixedly connected to a fixed plate, the upper side of the third mounting rod is fixedly connected to an electric push rod, the inner side of the electric push rod is fixedly connected to a movable plate, and push blocks are fixedly connected to both sides of one side of the movable plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model provides a special-shaped gear to facilitate grabbing of objects from different angles. When the first motor is started, the first motor drives the second gear to rotate through the first gear, and the second gear drives the limiting plate to rotate with the second gear as the axis through the sleeve and the second mounting rod. The limiting plate drives the special-shaped gear to rotate with the second gear as the axis through the connecting block and the connecting plate. At the same time, the special-shaped gear drives the grasping assembly to rotate with the second gear as the axis through the fixing plate. The second motor is started, and the second motor drives the special-shaped gear to rotate with the special-shaped gear as the axis through the third gear. The special-shaped gear drives the grasping assembly to rotate with the special-shaped gear as the axis through the fixing plate.

Through such a configuration, it is convenient to grasp the object from different angles, and the grasping needs for objects in various situations are met.

[0014] 2. The utility model facilitates the grasping of objects by setting up the mounting bracket. When the electric push rod is started, the electric push rod drives the push block to move outward through the movable plate, and the push block squeezes the mounting bracket. Because one side of the mounting bracket is fixedly connected with a rotating shaft, the push block squeezes the two mounting brackets and rotates around the rotating shaft. The outer sides of the two mounting brackets approach each other during rotation, and the mounting bracket drives the two pressure plates to approach each other through the second spring, the mounting plate, and the transmission rod. The two pressure plates approach each other to clamp the objects. Through such a setting, it is convenient to grasp the objects.

[0015] 3. The utility model reduces the situation where the object is damaged due to excessive force when grabbing the object by setting the second spring. When the mounting bracket drives the two pressure plates closer together through the second spring, the mounting plate and the transmission rod, and the two pressure plates approach to clamp the object, if the movement force of the mounting bracket is too large, the force is buffered by the second spring, thereby reducing the force of the mounting bracket driving the two pressure plates through the second spring, the mounting plate and the transmission rod, thereby protecting the object. Through such a setting, the situation where the object is damaged due to excessive force when grabbing the object is reduced.

[0016] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

The limiting plate 9 drives the special-shaped gear 12 to rotate with the second gear 6 as the axis through the connecting block and the connecting plate 11. At the same time, the special-shaped gear 12 drives the grasping assembly to rotate with the second gear 6 as the axis through the fixing plate. The second motor 7 is started, and the second motor 7 drives the special-shaped gear 12 to rotate with the special-shaped gear 12 as the axis through the third gear 8. The special-shaped gear 12 drives the grasping assembly to rotate with the special-shaped gear 12 as the axis through the fixing plate. At this time, the grasping assembly can be rotated to the required angle to grasp the object. Through such a configuration, it is convenient to grasp the objects from different angles, and meets the grasping needs of objects in various situations.

[0027] like Figure 1-Figure 4As shown, a first mounting rod is fixedly connected to the bottom of the first motor 2, a fixing flange 1 is fixedly connected to the outer side of the first mounting rod, a connecting rod is fixedly connected to the inner side of the fixing flange 1, a clamping plate 4 is fixedly connected to the inner side of the connecting rod, a connecting hole is opened on one side of the second gear 6, the connecting rod passes through the connecting hole, and the clamping plate 4 is movably sleeved in the sleeve 5. Through such an arrangement, the grasping device can be fixed to the industrial robot through the fixing flange 1, and the sleeve 5 is sleeved on the outer side of the clamping plate 4 and can rotate.

[0028] like Figure 1-Figure 7 As shown, the gripping assembly includes a third mounting rod, the inner side of the third mounting rod is fixedly connected to the fixed plate, the upper side of the third mounting rod is fixedly connected to an electric push rod 13, the inner side of the electric push rod 13 is fixedly connected to a movable plate, and both sides of one side of the movable plate are fixedly connected to push blocks 14. Through such an arrangement, the electric push rod 13 can drive the push block 14 to move through the movable plate.

[0029] like Figure 1-Figure 7 As shown, the outer sides of the two push blocks 14 are both abutted with mounting brackets 15, and the middle and lower parts of the two mounting brackets 15 are fixedly connected with rotating shafts, and the outer sides of the two rotating shafts are movably sleeved with mounting blocks, and the middle parts of the two mounting blocks are fixedly connected with the third mounting rod, and one end of the two rotating shafts is fixedly connected with a sealing plate. Through such an arrangement, the electric push rod 13 is started, and the electric push rod 13 drives the push block 14 to move outward through the movable plate, and the push block 14 squeezes the mounting bracket 15. Because one side of the mounting bracket 15 is fixedly connected with the rotating shaft, the push block 14 squeezes the two mounting brackets 15 to rotate around the rotating shaft as the axis, and the outer sides of the two mounting brackets 15 approach during rotation. At the same time, the mounting bracket 15 drives the first spring 16 to stretch through the transmission plate, and the mounting bracket 15 drives the two pressing plates 19 to approach through the second spring 17, the mounting plate 18, and the transmission rod. The two pressing plates 19 approach to clamp the objects. Through such an arrangement, it is convenient to grasp the objects.

[0030] like Figure 1-Figure 7 As shown, a transmission plate is fixedly connected to the top of the two mounting brackets 15, and a first spring 16 is fixedly connected between the two transmission plates. Through such an arrangement, when the two push blocks 14 no longer push the mounting brackets 15 to move, the first spring 16 drives the two mounting brackets 15 to reset through the transmission plate.

[0031] like Figure 1-Figure 7As shown, two mounting holes are equidistantly provided on the outer sides of the two mounting brackets 15, and transmission rods are passed through and connected to the four mounting holes. The two transmission rods on the same side form a group, and the inner sides of the two groups of transmission rods are fixedly connected with pressure plates 19, and the outer sides of the two groups of transmission rods are fixedly connected with mounting plates 18. The inner sides of the two mounting plates 18 are equidistantly fixedly connected with two second springs 17, and the inner sides of the four second springs 17 are fixedly connected to the adjacent mounting brackets 15, and the four second springs 17 are movably sleeved on the outer sides of the four transmission rods. Through such an arrangement, when the mounting bracket 15 drives the two pressure plates 19 to approach through the second springs 17, the mounting plate 18, and the transmission rod, and the two pressure plates 19 approach to clamp the objects, if the movement force of the mounting bracket 15 is too large, the force is buffered by the second spring 17, thereby reducing the force of the mounting bracket 15 driving the two pressure plates 19 through the second springs 17, the mounting plate 18, and the transmission rod, thereby protecting the objects.

[0032] It should be noted that, when in use, the gripping device is fixedly connected to the industrial robot through the fixing flange 1, the first motor 2 is started, the first motor 2 drives the second gear 6 to rotate through the first gear 3, the second gear 6 drives the limiting plate 9 to rotate with the second gear 6 as the axis through the sleeve 5 and the second mounting rod, the limiting plate 9 drives the special-shaped gear 12 to rotate with the second gear 6 as the axis through the connecting block and the connecting plate 11, and at the same time, the special-shaped gear 12 drives the gripping assembly to rotate with the second gear 6 as the axis through the fixing plate, the second motor 7 is started, and the second motor 7 drives the special-shaped gear 12 to rotate with the special-shaped gear 12 as the axis through the third gear 8, and the special-shaped gear 12 drives the gripping assembly to rotate with the second gear 6 as the axis.

The electric push rod 13 drives the push block 14 to move outward through the movable plate, and the push block 14 squeezes the mounting bracket 15. Because one side of the mounting bracket 15 is fixedly connected to a rotating shaft, the push block 14 squeezes the two mounting brackets 15 to rotate around the rotating shaft as the axis, and the outer sides of the two mounting brackets 15 approach during rotation. The mounting bracket 15 drives the two pressure plates 19 to approach through the second spring 17, the mounting plate 18, and the transmission rod, and the two pressure plates 19 approach to clamp the object.

[0033] When the mounting bracket 15 drives the two pressure plates 19 to approach each other through the second spring 17, the mounting plate 18, and the transmission rod, and the two pressure plates 19 approach each other to clamp the object, if the movement force of the mounting bracket 15 is too large, the force is buffered by the second spring 17, thereby reducing the force of the mounting bracket 15 driving the two pressure plates 19 through the second spring 17, the mounting plate 18, and the transmission rod, thereby protecting the object.
