As shown in fig. 1 to 3, the gripper has a connecting portion 10 for connection with a drive mechanism, and includes a gripper body, a first gripping assembly, a second gripping assembly, and a third drive structure 50. Wherein the connecting portion 10 is provided on the jig body. The first clamping assembly is movably arranged on the clamp body, and comprises a first clamping part 32 and a first driving structure 31 for driving the first clamping part 32 to move. The second clamping assembly is movably arranged on the clamp body, and comprises a second clamping part 42 and a second driving structure 41 for driving the second clamping part 42 to move. The third driving structure 50 is arranged on the clamp body, and the third driving structure 50 drives the first clamping assembly and the second clamping assembly to synchronously move in the opposite direction or synchronously move in the opposite direction; the second gripping section 42 is disposed opposite to the first gripping section 32 to form a gripping space to drive the first and second gripping sections 32 and 42 to move by the first and second driving structures 31 and 41 to grip or release the gripped member 80.

With the technical solution of the present embodiment, when the gripper is used to grip the gripped object 80, the third driving structure 50 drives the first gripping assembly and the second gripping assembly to move synchronously towards each other, and then the first driving structure 31 of the first gripping assembly drives the first gripping part 32 to move towards the second gripping assembly, and the second driving structure 41 of the second gripping assembly drives the second gripping part 42 to move towards the first gripping assembly, so that the gripping space is reduced until the first gripping part 32 and the second gripping part 42 are gripped by the gripper 80. Then, the driving mechanism drives the clamp to move, so as to realize the transportation of the clamped piece 80 by the clamp, when the clamped piece is transported to the target position, the first driving structure 31 drives the first clamping part 32 to move towards the direction away from the second clamping assembly, and the second driving structure 41 of the second clamping assembly drives the second clamping part 42 to move towards the direction away from the first clamping assembly, so that the clamping space is increased until the first clamping part 32 and the second clamping part 42 are released by the clamped piece 80.

Compared with the manual hoisting mode in the prior art, the clamp in the embodiment enables the worker to clamp, transport and release the clamped piece more easily and conveniently, saves time and labor, reduces the labor intensity of the worker, and solves the problem of lower working efficiency of the clamp in the prior art.

In this embodiment, anchor clamps are in the centre gripping with release by holder 80 in-process, need not the staff and operate by holder 80, and then avoid the staff injured, have promoted the safety in utilization of anchor clamps. Meanwhile, the third driving structure 50 drives the first clamping part 32 and the second clamping part 42 to perform a preliminary movement, and then the first driving structure 31 drives the first clamping part 32 to move, and the second driving structure 41 drives the second clamping part 42 to move, so as to achieve a secondary positioning of the first clamping part 32 and the second clamping part 42 by the fixture, so that the first clamping part 32 and the second clamping part 42 precisely move to the position of the clamped piece 80, so as to achieve a precise movement of the first clamping part 32 and the second clamping part 42, and achieve unmanned automatic production.

Alternatively, when the third driving structure 50 drives the first gripping part 32 and the second gripping part 42 to move, the moving speed of the first gripping part 32 and the second gripping part 42 is V1, when the first driving structure 31 drives the first gripping part 32 to move, the moving speed of the first gripping part 32 is V2, when the second driving structure 41 drives the second gripping part 42 to move, the moving speed of the second gripping part 42 is V3, and the value of V1 is greater than the values of V2 and V3. Like this, above-mentioned setting is shortening the anchor clamps centre gripping by under the time-consuming condition of holder 80, prevents that anchor clamps from causing structural damage to by holder 80, promotes the centre gripping efficiency of anchor clamps.

In the embodiment, the clamp is mainly used for clamping and releasing the power battery of the automobile.

In the present embodiment, the distance of the relative movement of the first clamping part 32 and the second clamping part 42 driven by the third driving structure 50 is in the range of 500-900 mm.

As shown in fig. 1 and 2, the first clamping assembly further includes a first sliding member 33, a second sliding member 34, and a limiting structure 35. Wherein the first drive structure 31 is arranged on the first slide 33. The first clamping part 32 is disposed on the second sliding member 34, and the first driving structure 31 drives the second sliding member 34 to move so that the second sliding member 34 drives the first clamping part 32 to move. The limiting structure 35 is arranged on the first sliding part 33, and the limiting structure 35 is positioned on one side of the first sliding part 33 close to the clamped part 80, so that the limiting structure 35 is abutted to the clamped part 80. Thus, the clamp can clamp clamped pieces 80 with different specifications and sizes, and the applicability of the clamp is improved.

Specifically, in the process of gripping the gripped member 80 by the gripper, the third driving structure 50 drives the first gripping assembly to move toward the second gripping assembly to realize the preliminary movement of the first gripping section 32. When the first clamping part 32 moves to a position closer to the clamped part 80, the first driving structure 31 drives the first clamping part 32 to move continuously, so that the first clamping part 32 is clamped and supported by the clamped part 80, and the clamped part 80 is clamped by the clamp. When the driving mechanism drives the clamp to move to the target position, the first driving mechanism 31 drives the first clamping part 32 to move reversely, so that the first clamping part 32 is released by the clamping piece 80. Thereafter, the third driving structure 50 drives the first clamping assembly to move away from the second clamping assembly, so as to move the first clamping part 32 to the initial position. In the above process, the limiting structure 35 limits and stops the clamped piece 80 to ensure that the first clamping part 32 is fully released by the clamped piece 80.

As shown in fig. 1, the clamp body has a supporting beam 21, the first sliding member 33 is slidably disposed at the upper end of the supporting beam 21, the second sliding member 34 is sleeved on the supporting beam 21, the second sliding member 34 includes a first sleeving portion 341 and a first body portion 342, the first clamping portion 32 is connected to a side of the first body portion 342 away from the first sleeving portion 341, the first sleeving portion 341 is sleeved on the supporting beam 21, and the first body portion 342 has an avoiding hole 342a for the limiting structure 35 to pass through, so that when the first sliding member 33 and the second sliding member 34 move relatively, the limiting structure 35 avoids the second sliding member 34 through the avoiding hole 342 a; the first body 342 and the first clamping part 32 are disposed at an angle. Therefore, the arrangement not only enables the structural layout of the clamp to be more compact, but also avoids the phenomenon of structural interference of the clamp in the operation process. Simultaneously, the above-mentioned setting of second slider 34 can promote the overall structure intensity of anchor clamps, and the life of extension anchor clamps avoids anchor clamps structure to damage and leads to the condition emergence that the staff is injured. The structure is simple, and easy to process and realize.

Specifically, the driving mechanism is connected to the gripper through the connecting portion 10, and the first gripping section 32 and the second gripping section 42 are located below the connecting portion 10. When the clamp clamps the clamped piece 80, the first clamping part 32 and the second clamping part 42 are lifted by the clamped piece 80, and the first body part 342 performs limit stop on the side surface of the clamped piece 80, so that the clamping efficiency of the clamp is prevented from being influenced by the relative movement of the clamp and the clamped piece 80. Meanwhile, in the above process, the weight of the clamped member 80 is mainly concentrated on the second slider 34, and does not act on the first driving structure 31 provided on the first slider 33 to protect the first driving structure 31.

Note that the structure of the second slider 34 is not limited to this. In other embodiments not shown in the drawings, a fourth slide is mounted at the lower end of the support beam to reduce the weight of the clamp.

As shown in fig. 1 and 2, the second grasping assembly further includes a third slider 43 and a fourth slider 44. Wherein the second drive structure 41 is arranged on the third slide 43. The second clamping part 42 is disposed on the fourth sliding member 44, and the second driving structure 41 drives the fourth sliding member 44 to move so that the fourth sliding member 44 drives the second clamping part 42 to move. Thus, the clamp can clamp clamped pieces 80 with different specifications and sizes, and the applicability of the clamp is improved.

Specifically, in the process of gripping the gripped member 80 by the gripper, the third driving structure 50 drives the first gripping member and the second gripping member to move toward each other to realize the preliminary movement of the first gripping section 32 and the second gripping section 42. When the first clamping part 32 and the second clamping part 42 move to a closer distance from the clamped piece 80, the first driving structure 31 drives the first clamping part 32 to move continuously, and the second driving structure 41 drives the second clamping part 42 to move continuously, so that the first clamping part 32 and the second clamping part 42 are clamped and lifted by the clamped piece 80, and the clamped piece 80 is clamped by the clamp. When the driving mechanism drives the clamp to move to the target position, the first driving structure 31 drives the first clamping part 32 to move reversely, and the second driving structure 41 drives the second clamping part 42 to move reversely, so that the first clamping part 32 and the second clamping part 42 are released by the clamp 80. Thereafter, the third driving structure 50 drives the first and second grasping assemblies to move back and forth, so that the first and second grasping portions 32 and 42 move to the initial positions.

Therefore, the arrangement not only enables the structural layout of the clamp to be more compact, but also avoids the phenomenon of structural interference of the clamp in the operation process. Meanwhile, the overall structural strength of the clamp can be improved by the aid of the fourth sliding part 44, the service life of the clamp is prolonged, and the condition that the clamp is damaged to cause injury to workers is avoided. The structure is simple, and easy to process and realize.

Specifically, when the clamp clamps the clamped element 80, the first clamping part 32 and the second clamping part 42 will be lifted by the clamped element 80, and the second body 442 of the fourth sliding part 44 will perform a limit stop on the side surface of the clamped element 80, so as to avoid the clamping efficiency of the clamp from being affected by the relative movement between the clamp and the clamped element 80. Meanwhile, in the above process, the weight of the clamped member 80 is mainly concentrated on the fourth slider 44, and does not act on the second driving structure 41 provided on the third slider 43 to protect the second driving structure 41.

Note that the structure of the fourth slider 44 is not limited to this. In other embodiments not shown in the drawings, a fourth slide is mounted at the lower end of the support beam to reduce the weight of the clamp.

Specifically, the clamp includes a third driving structure 50, the third driving structure 50 transmits power to the first transmission member 61 and the second transmission member 62, and then transmits power to the first sliding member 33 and the third sliding member 43 through the first transmission member 61 and the second transmission member 62, so as to realize the movement of the first clamping assembly and the second clamping assembly, that is, the first clamping assembly and the second clamping assembly are driven by one third driving structure, thereby reducing the number of the driving structures and the occupied space.

The number of the third driving structures 50 is not limited to this. Optionally, the clamp comprises two third drive structures 50, wherein one third drive structure 50 drives the first transmission member 61 and the other third drive structure 50 drives the second transmission member 62.

As shown in fig. 3, the first transmission member 61 and the second transmission member 62 are screw rods, the first transmission member 61 and the second transmission member 62 are connected by a coupling 90, and the thread direction of the outer surface of the first transmission member 61 is opposite to the thread direction of the outer surface of the second transmission member 62, so that the first sliding member 33 and the third sliding member 43 approach or separate from each other when the first transmission member 61 and the second transmission member 62 rotate simultaneously. Like this, realize the first slider 33 and the third slider 43 move in opposite directions or back-to-back through a third drive structure 50, and then make the structure of anchor clamps simpler, easy dismouting has reduced staff's intensity of labour.

As shown in fig. 1 to 4, the third driving structure 50 is a motor, and a motor shaft of the motor is connected to the first transmission member 61 to drive the first sliding member 33 to move. Specifically, the third driving structure 50 drives the first transmission member 61 to move, and then the first transmission member 61 drives the second transmission member 62 to move, and the first transmission member 61 and the second transmission member 62 move synchronously. Like this, drive the rotatory automatic adjustment of lead screw through the motor and press from both sides and get the space to can realize the compatibility to different specification and dimension by holder 80 (automobile power battery), further strengthen the practicality of anchor clamps.

As shown in fig. 1, the clamp further includes a first bearing block 71 and a second bearing block 72, the second sliding member 34 has a first through hole for the support beam 21 to pass through and a second through hole for the first transmission member 61 to pass through, the first bearing block 71 is disposed between a hole wall of the first through hole and the support beam 21, the fourth sliding member 44 has a third through hole for the support beam 21 to pass through and a fourth through hole for the second transmission member 62 to pass through, and the second bearing block 72 is disposed between a hole wall of the third through hole and the support beam 21. Thus, the arrangement can reduce the pressure of the second sliding part 34 and the fourth sliding part 44 on the supporting beam 21, and avoid the influence on the normal use of the clamp caused by the structural damage of the supporting beam 21.

Thereafter, the first driving structure 31 (first air cylinder) drives the second slider 34 to move so as to move the first gripping part 32; the second driving structure 41 (second air cylinder) drives the fourth slider 44 to move, so that the second gripping section 42 moves, to adjust the gripping spaces of the first gripping part 32 and the second gripping part 42 and to push the first gripping part 32 and the second gripping part 42 to the bottom of the gripped member 80 (power battery for automobile), the bottom of the clamped member 80 (the automobile power battery) is held while the clamped member 80 (the automobile power battery) is clamped, the entire weight of the clamped member 80 (the power battery of the automobile) is concentrated on the second slide member 34 and the fourth slide member 44, the first driving structure 31 (the first air cylinder) and the second driving structure 41 (the second air cylinder) perform only the pushing and pulling action, there is little force applied in the radial direction of the first drive structure 31 (first cylinder) and the second drive structure 41 (second cylinder) and therefore no damage to both.
