The grab claw 4 consists of a fixed cylinder 41 and a sliding block 42. A plurality of grab claws 421 are distributed in an annular shape at the bottom end of the sliding block 42. The sliding block 42 is located on the inner wall of the fixed cylinder 41 and is slidably connected to the fixed cylinder 41. The top end of the sliding block 42 is fixedly connected to the bottom end of the extrusion plate 12.

At this time, the power source mechanism 21 is controlled to operate, drive the output shaft 211 to retract, and then drive the grabbing movable frame 2 and the fixed frame 1 to approach each other, further drive the sliding plate 23 and the extrusion plate 12 to move away from each other, and then drive the fixed cylinder 4 The outer wall of the sliding block 42 slides downward to close the elastic claw 421, thereby fixing the oil wax piece 3 inside. Under the protection of the rubber package, the oil wax piece 3 is prevented from being damaged when being grabbed. After being grabbed, the external power component drives the oil wax piece grabbing mechanism and the clamped multiple oil wax pieces 3 to move to the next process for placement. By controlling the power source mechanism 21 to drive the output end 211 to extend, and then open under the elasticity of the elastic claw 421 itself, the grabbing operation of the oil wax piece 3 can be repeated.

[0029] The bottom end of the fixed frame 1 is fixedly connected to the first connecting column 11, the bottom end of the first connecting column 11 is fixedly connected to the extrusion plate 12, the top end of the extrusion plate 12 is fixedly connected to the limiting slide 121, the inner wall of the limiting slide 121 is slidably connected to the outer wall of the second connecting column 22, the top end of the grabbing movable frame 2 is fixedly connected with a power source mechanism 21, the outer side of the bottom end of the grabbing movable frame 2 is fixedly connected to the second connecting column 22, the bottom end of the second connecting column 22 is fixedly connected to the sliding plate 23, the sliding plate 23 is provided with a first fixing hole 231 inside, and the inner wall of the first fixing hole 231 is fixedly connected to the outer wall of the fixed cylinder 41.

[0030] The number of grabbing claws 4 is set to be multiple, and they are equidistantly distributed in a matrix inside the sliding plate 23. An oil wax part 3 is placed at the bottom end of the grabbing claws 4. The number of oil wax parts 3 is multiple and they are equidistantly distributed in a matrix.

The grabbing claws 421 are set to be elastic parts, and the outer wall of the bottom end of the grabbing claws 421 is provided with rubber packaging to eliminate damage to the oil wax part 3 during grabbing.

[0031] In summary, the utility model has the following working principles:

[0032] Organization composition and fixation:

[0033] The mechanism is mainly composed of a sliding mechanism and a fixing mechanism, and the two are connected by sliding.

[0034] The sliding mechanism comprises a grabbing movable frame 2, a power source mechanism 21, a second connecting column 22 and a sliding plate 23, which are fixedly connected to form a whole.

[0035] The fixing mechanism comprises a fixing frame 1, a first connecting column 11 and a pressing plate 12, which are also fixedly connected to form a stable structure.

[0036] The fixed frame 1 is fixedly connected to an external moving component (such as a robot arm) to ensure that the entire grasping mechanism can move to the outside of the oil wax part 3 to be grasped.

[0037] Power source and control system:

[0038] The power source mechanism 21 (such as a pneumatic push rod, an electric push rod or a hydraulic push rod) is electrically connected to an external electrical control system, and the extension and retraction of the power source mechanism 21 is controlled by the control system.

[0039] Crawl process:

[0040] When the mechanism moves to the outside of the oil wax piece 3 to be grasped and makes the oil wax piece 3 correspond to the grasping claw 4 one by one, the control system starts the power source mechanism 21.

[0041] The power source mechanism 21 drives the output shaft 211 to retract. Since one end of the output shaft 211 is fixedly connected to the top of the fixed frame 1, this will cause the grabbing movable frame 2 and the fixed frame 1 to approach each other.

[0042] Since the second connecting column 22 and the sliding plate 23 are fixedly connected to the grabbing movable frame 2, and the pressing plate 12 is fixedly connected to the fixed frame 1 via the first connecting column 11, the sliding plate 23 and the pressing plate 12 will move away from each other.

[0043] With the relative movement of the sliding plate 23 and the pressing plate 12 , the fixed cylinder 41 slides downward on the outer wall of the sliding block 42 , forcing the sliding block 42 and the multiple elastic claws 421 at the bottom end thereof to retract inward.

[0044] The retracted elastic claws 421 fix the inner oil wax part 3 under the protection of the rubber package to avoid damage to the oil wax part 3 during the grabbing process.

[0045] Release and move:

[0046] When the wax piece 3 needs to be released, the control system starts the power source mechanism 21 again to extend its output shaft 211 , driving the grabbing movable frame 2 and the fixed frame 1 to move away from each other, thereby releasing the wax piece 3 .

[0047] Subsequently, the entire grasping mechanism can be moved to the next working position driven by the external moving parts, ready for the next round of grasping work, thus completing the overall working process of the device.
