Description

Technical Field

[0001] This utility model relates to the field of clamping mechanisms, and more particularly to a jaw-type clamping mechanism. Background Technology

[0002] The grippers on existing mechanical clamping devices are often driven by electric or pneumatic drives to clamp the product. While the clamping stability is good, electric or pneumatic drives can easily damage the product. Furthermore, current mechanical clamping devices use rotating pins for assembly, which is inconvenient.

[0003] In existing technologies, such as the "link-type clamping mechanism" with Chinese authorization announcement number CN218462231U, there is a circular fixed plate. The piston rod of the cylinder at the top of the circular fixed plate is fixedly connected to the drive shaft. Three U-shaped fixed plates arranged at equal intervals at the bottom of the circular fixed plate are respectively provided with clamping components hinged to the drive shaft. Each clamping component includes a first connecting rod that is hinged to the drive shaft via a first hinge pin, to the U-shaped fixed plate via a second hinge pin, and to the gripper seat via a fifth hinge pin; a second connecting rod that is hinged to the U-shaped fixed plate via a third hinge pin and to the gripper seat via a fourth hinge pin; and a gripper fixedly located inside the gripper seat. The cylinder on this link-type clamping mechanism moves up and down, driven by the first and second connecting rods to perform radial clamping / releasing actions, which facilitates product clamping without damaging the product. Moreover, the link-type clamping components are connected by hinge pins, making assembly convenient.

[0004] When using clamping mechanisms in existing technologies, the large number of clamping linkage components and the complex clamping structure make the clamping mechanism prone to wear and deformation when clamping continuously shaking components, resulting in low stability of the clamping mechanism.

[0005] Therefore, it is necessary to provide a gripper-type clamping mechanism to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a claw-type clamping mechanism, which solves the problem that the clamping mechanism is prone to wear and deformation when clamping continuously shaking parts due to the large number of clamping linkage components and the complex clamping structure, thus resulting in low stability of the clamping mechanism.

[0007] To solve the above-mentioned technical problems, the present invention provides a gripper-type clamping mechanism, including a limiting box, a protective box fixedly connected to the side of the limiting box, a hydraulic column fixedly installed inside the protective box, a flange fixedly connected to one end of the hydraulic column, a hinge plate movably sleeved on the outside of the flange, a clamping body movably sleeved on one end of the hinge plate, a positioning shaft movably sleeved inside the clamping body, a slot formed at one end of the clamping body, a locking block movably sleeved inside the limiting box, a sliding ball movably sleeved at the bottom of the inner cavity of the limiting box, and a limiting plate fixedly connected to the bottom of the inner cavity of the limiting box.

[0008] Preferably, the card block is adapted to the card slot, and the front shape of the card block is I-shaped.

[0009] Preferably, the hydraulic column is located at the center of the side of the limiting box, and the hydraulic column and the limiting box are parallel to each other.

[0010] Preferably, the limiting box is made of manganese steel and is compatible with the clamp body.

[0011] Preferably, there are two positioning axes, which are symmetrically distributed about the hydraulic column as the axis of symmetry.

[0012] Preferably, the number of sliding balls is several, and the several sliding balls are evenly distributed directly below the slot.

[0013] Preferably, the limiting plate is in close contact with the bottom of the hinge plate, and the limiting plate and the flange are parallel to each other.

[0014] Compared with related technologies, the gripper-type clamping mechanism provided by this utility model has the following advantages:

[0015] This utility model provides a claw-type clamping mechanism. By setting a locking block, when the locking block is clamped, it is sleeved inside the limiting box. At this time, the hydraulic column is activated, which drives the two clamping bodies to rotate. This causes one end of the clamping body to retract the slot, so that the locking block is locked and limited inside the slot. That is, the locking block is clamped and fixed inside the limiting box. This allows the slot and the limiting box to limit and lock the wobbling locking block, thus avoiding the problem of frequent impacts on the clamping body when the locking block shakes, which would cause damage to the clamping body. This improves the impact resistance of the clamping mechanism during use.

[0016] By setting a positioning shaft, when the hinge plate drives the clamp body to rotate, the positioning shaft can position the rotating circle of the clamp body, so that the clamp body can form a force-saving lever structure, thereby improving the clamping strength of the clamping end of the clamp body, thus improving the clamping strength of the object, and thus improving the practicality of the clamping mechanism.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of the gripper-type clamping mechanism provided by this utility model; Figure 2 for Figure 1 A cross-sectional view of the protective box in the gripper-type clamping mechanism shown; Figure 3 for Figure 1 The front view of the jaw clamping mechanism shown; Figure 4 for Figure 1 The diagram shows a front view of the clamping body in a jaw-type clamping mechanism. The jaw-type clamping mechanism includes a limiting box 1, a protective box 2 fixedly connected to the side of the limiting box 1, a hydraulic column 3 fixedly installed inside the protective box 2, a flange 4 fixedly connected to one end of the hydraulic column 3, a hinge plate 5 movably sleeved on the outside of the flange 4, a clamping body 6 movably sleeved on one end of the hinge plate 5, a positioning shaft 7 movably sleeved inside the clamping body 6, a slot 8 at one end of the clamping body 6, a locking block 9 movably sleeved inside the limiting box 1, a sliding ball 10 movably sleeved at the bottom of the inner cavity of the limiting box 1, and a limiting plate 11 fixedly connected to the bottom of the inner cavity of the limiting box 1.

[0024] The locking block 9 is adapted to the locking slot 8, and the front shape of the locking block 9 is I-shaped. By setting the locking block 9, when the locking block 9 is clamped, it is sleeved inside the limiting box 1. At this time, the hydraulic column 3 is activated, which drives the two clamping bodies 6 to rotate, so that one end of the clamping body 6 drives the locking slot 8 to retract, so that the locking block 9 is locked and limited inside the locking slot 8. That is, the locking block 9 is clamped and fixed inside the limiting box 1, so that the locking slot 8 and the limiting box 1 can limit and lock the shaking locking block 9, thus avoiding the problem of frequent impacts of the locking block 9 on the clamping body 6 when it shakes, which would cause damage to the clamping body 6, thereby improving the impact resistance of the clamping mechanism during use.

[0025] The hydraulic column 3 is located in the center of the side of the limit box 1, and the hydraulic column 3 and the limit box 1 are parallel to each other. By setting the hydraulic column 3, when the clamping block 9 is clamped and fixed, the clamping block 9 is sleeved inside the limit box 1. At this time, the hydraulic column 3 is activated, so that the hydraulic column 3 can push the flange 4 to move, thereby causing the hydraulic column 3 to drive the two hinge plates 5 to flip, that is, to drive one end of the clamping body 6 to flip and press against the side of the clamping block 9, thereby achieving the clamping and fixing effect of the clamping block 9.

[0026] The limiting box 1 is made of manganese steel and is compatible with the clamp body 6. By setting the limiting box 1, when clamping and fixing objects, the limiting box 1 can enclose and protect the hinge plate 5 which is frequently flipped, thus preventing the clamp body 6 from rusting and getting dirty when external debris falls onto the surface of the hinge plate 5, which would reduce the service life of the clamp body 6 and improve the service life of the clamping mechanism.

[0027] There are two positioning shafts 7, which are symmetrically distributed about the hydraulic column 3. By setting the positioning shafts 7, when the hinge plate 5 drives the clamp body 6 to rotate, the positioning shafts 7 can position the rotating circle of the clamp body 6, so that the clamp body 6 can form a force-saving lever structure, thereby improving the clamping strength of the clamping end of the clamp body 6, and thus improving the clamping strength of the object, thereby improving the practicality of the clamping mechanism.

[0028] There are several sliding balls 10, which are evenly distributed below the slot 8. By setting the sliding balls 10, when the card block 9 is clamped and fixed frequently, the sliding balls 10 can limit the card block 9 entering the limit box 1, thereby avoiding the problem of friction between the card block 9 and the bottom of the inner cavity of the limit box 1 when it moves, thus improving the smoothness of the card block 9 when it is pulled out and moved.

[0029] The limiting plate 11 is in close contact with the bottom of the hinge plate 5, and the limiting plate 11 is parallel to the flange 4. By setting the limiting plate 11, when the hinge plate 5 frequently drives the clamping body 6 to rotate, the limiting plate 11 can limit the rotating hinge plate 5, thereby avoiding the problem of the hinge plate 5 shaking up and down when rotating and clamping, and thus frequently colliding with the inner wall of the limiting box 1, thereby improving the stability of the hinge plate 5's position during operation.

[0030] The working principle of the gripper-type clamping mechanism provided by this utility model is as follows:

[0031] Step 1: First, when clamping block 9, place it inside the limiting box 1. Then, activate the hydraulic cylinder 3, causing the two clamping bodies 6 to rotate. This causes one end of the clamping body 6 to retract the slot 8, locking block 9 inside the slot 8. In other words, block 9 is clamped and fixed inside the limiting box 1. This allows the slot 8 and the limiting box 1 to restrain and lock the wobbling block 9, preventing frequent impacts from block 9 to the clamping body 6 and thus improving the impact resistance of the clamping mechanism. When fixing, the clamping block 9 is fitted inside the limiting box 1. At this time, the hydraulic column 3 is activated, which pushes the flange 4 to move. This causes the hydraulic column 3 to rotate the two hinge plates 5, which in turn rotates one end of the clamping body 6 and presses it against the side of the clamping block 9, thus achieving the clamping and fixing effect of the clamping block 9. When clamping and fixing objects, the limiting box 1 can enclose and protect the hinge plates 5 that are frequently rotated, thus preventing the clamping body 6 from rusting and getting dirty when external debris falls onto the surface of the hinge plates 5, which would reduce the service life of the clamping body 6. This improves the service life of the clamping mechanism.

[0032] Step 2: When the hinge plate 5 drives the clamp body 6 to rotate, the positioning shaft 7 positions the rotating circle of the clamp body 6, allowing the clamp body 6 to form a force-saving lever structure, thereby improving the clamping strength of the clamping end of the clamp body 6, and thus improving the clamping strength of the object, thereby improving the practicality of the clamping mechanism. When the locking block 9 is clamped and fixed frequently, the sliding ball 10 limits the locking block 9 entering the limit box 1, thus avoiding the problem of friction between the locking block 9 and the bottom of the inner cavity of the limit box 1 when the locking block 9 moves, thereby improving the smoothness of the locking block 9 when it is pulled out and moved. When the hinge plate 5 frequently drives the clamp body 6 to rotate, the limit plate 11 limits the rotating hinge plate 5, thus avoiding the problem of the hinge plate 5 shaking up and down when rotating and clamping, and thus frequently colliding with the inner wall of the limit box 1, thereby improving the stability of the hinge plate 5's position when working.

[0033] Compared with related technologies, the gripper-type clamping mechanism provided by this utility model has the following advantages:

[0034] By setting the locking block 9, when the locking block 9 is clamped, it is sleeved inside the limiting box 1. At this time, the hydraulic column 3 is activated, which drives the two clamping bodies 6 to rotate. This causes one end of the clamping body 6 to retract the slot 8, so that the locking block 9 is locked and limited inside the slot 8. That is, the locking block 9 is clamped and fixed inside the limiting box 1. This allows the slot 8 and the limiting box 1 to limit and lock the shaking locking block 9, thus avoiding the problem of frequent impacts of the locking block 9 on the clamping body 6, which would cause damage to the clamping body 6. This improves the impact resistance of the clamping mechanism during use.
