Description

Technical Field

[0001] This invention relates to the field of automated operation technology for robots in continuous casting areas of steel plants, and in particular to a hydraulic cylinder mounting mechanism with a self-locking pin. Background Technology

[0002] In the steelmaking plant, molten steel that has passed the smelting process is transported to the ladle turret receiving position on the continuous casting machine. At the receiving position, a hydraulic cylinder is manually installed onto the sliding gate mechanism at the bottom of the ladle, and a pin is inserted to prevent the hydraulic cylinder from detaching and causing a safety accident. This step requires two steps if done manually. However, when using a robot, it is difficult to install the hydraulic cylinder and then insert the pin. Therefore, an automated mechanism needs to be developed to simultaneously perform the functions of installing the hydraulic cylinder and inserting the pin. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by proposing a hydraulic cylinder mounting mechanism with a self-locking pin.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a hydraulic cylinder mounting mechanism with self-locking pins, comprising a hydraulic cylinder, a handle welded to the side of the hydraulic cylinder, two sets of fixing seats elastically installed inside the handle, two sets of pins respectively installed on opposite sides of the two sets of fixing seats, the two sets of pins respectively fitting and penetrating the front and rear end faces inside the handle, a retaining seat provided on the outside of the hydraulic cylinder, a first connecting hole being opened through the front and rear end face edges of the retaining seat, the pins being aligned with the first connecting hole, two sets of insert plates respectively fixedly installed at the ends of the two sets of fixing seats, a gripper cylinder provided on the side of the insert plate, a connecting plate installed on the side of the gripper cylinder, two sets of claws symmetrically embedded on the claws of the gripper cylinder, the claws cooperating with the insert plate.

[0005] Preferably, two sets of No. 2 connection holes are symmetrically opened on opposite sides of the two sets of plug-in plates, the claws cooperate with the No. 2 connection holes, the plug-in plates and the fixing bases are integrally formed, and through holes are opened on opposite sides of the two sets of fixing bases, and the pins are embedded in the inside of the through holes.

[0006] Preferably, two sets of guide posts are symmetrically fitted and installed between the front and rear end faces of the handle. The two sets of guide posts are located on the same vertical line, and guide holes are opened through the opposite faces of the two sets of fixing seats. The guide posts are fitted and installed through the guide holes.

[0007] Preferably, two sets of spring bodies are wound around the outer sides of the two sets of guide columns respectively. The two sets of spring bodies are staggered. The upper end face of the fixing seat at the rear and the lower end face of the fixing seat at the front are provided with notches and slots. The spring body at the upper part is located in the notch and slot on the fixing seat at the rear, and the spring body at the lower part is located in the notch and slot on the fixing seat at the front.

[0008] Preferably, the upper spring body is located between the inner rear end face of the handle and the rear end face of the front fixing seat, and the lower spring body is located between the inner front end face of the handle and the front end face of the rear fixing seat.

[0009] Preferably, the front and rear ends of the handle are provided with grooves, and the front and rear ends of the two sets of guide posts are inlaid with bearing seats, which are inlaid inside the grooves.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The gripper cylinder connected to the robot moves to the vicinity of the handle. Under the action of the gripper cylinder, the gripper closes and clamps the two sets of plug-in plates. At this time, the gripper inserts into the second connection hole on the plug-in plate. Then, the gripper continues to close, causing the pin on the fixed seat to retract. The robot then inserts the combination of gripper cylinder, handle, and hydraulic cylinder into the mounting bracket. Subsequently, under the action of the gripper cylinder, the gripper opens and releases the two sets of plug-in plates. The pin is pushed out by the spring body to insert into the first connection hole on the mounting bracket, locking the handle and the mounting bracket. Then, the gripper on the gripper cylinder continues to open, separating the gripper, the plug-in plate, and the second connection hole. The robot then drives the gripper cylinder to detach from the plug-in plate. The installation of the hydraulic cylinder and the mounting bracket is completed, and the pin is inserted into the first connection hole, ensuring that the hydraulic cylinder will not detach from the mounting bracket, thus ensuring safety. This mechanism can simultaneously complete the functions of installing the hydraulic cylinder and inserting the pin, thereby effectively reducing the labor intensity of manual labor and improving safety.

[0018] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] like Figures 1-5 The hydraulic cylinder mounting mechanism with self-locking pins shown includes a hydraulic cylinder 1. A handle 2 is welded to the side of the hydraulic cylinder 1. Two sets of fixed seats 10 are elastically installed inside the handle 2, and the handle 2 serves to support the two sets of fixed seats 10. Two sets of pins 12 are respectively installed on the opposite sides of the two sets of fixed seats 10. The two sets of pins 12 are respectively fitted and penetrated into the front and rear end faces of the handle 2. A retaining seat 3 is provided on the outside of the hydraulic cylinder 1. A connecting hole 4 is opened through the front and rear end edges of the retaining seat 3. The pin 12 is aligned with the first connecting hole 4. The pin 12 is used to lock the pin into the first connecting hole 4 on the card holder 3. Two sets of plug-in plates 5 are fixedly installed at the ends of the two sets of fixed seats 10 respectively. A gripper cylinder 6 is provided on the side of the plug-in plate 5. A connecting plate 7 is installed on the side of the gripper cylinder 6. The connecting plate 7 is used to connect with the robot. Two sets of claws 8 are symmetrically embedded on the gripper of the gripper cylinder 6. The gripper cylinder 6 is used to drive the claws 8 to move inward or outward. The claws 8 cooperate with the plug-in plate 5.

[0020] Two sets of No. 2 connecting holes 9 are symmetrically opened on opposite sides of the two sets of plug-in plates 5. The claws 8 cooperate with the No. 2 connecting holes 9. The cooperation between the claws 8 and the No. 2 connecting holes 9 improves the firmness of the clamping cylinder 6 when clamping the two sets of plug-in plates 5. The plug-in plates 5 and the fixing base 10 are integrally formed. The opposite sides of the two sets of fixing bases 10 are provided with through holes. The pins 12 are embedded in the through holes. The through holes serve to fix the pins 12 on the fixing base 10.

[0021] Two sets of guide posts 15 are symmetrically fitted and installed between the front and rear end faces of the handle 2. The two sets of guide posts 15 are located on the same vertical line. Guide holes are opened through the opposite faces of the two sets of fixing seats 10. The guide posts 15 fit into the guide holes. The cooperation between the guide holes and the guide posts 15 guides the fixing seats 10, so that the fixing seats 10 move in a straight line.

[0022] Two sets of spring bodies 11 are wound around the outer sides of the two sets of guide posts 15 respectively. The two sets of spring bodies 11 are staggered. The spring bodies 11 push the fixed seats 10, so that the two sets of fixed seats 10 move and reset in opposite directions. The upper end face of the fixed seat 10 at the rear and the lower end face of the fixed seat 10 at the front are both provided with notches and slots 16. The upper spring body 11 is located in the notch and slot 16 on the rear fixed seat 10, and the lower spring body 11 is located in the notch and slot 16 on the front fixed seat 10. The notches and slots 16 serve to accommodate the spring bodies 11.

[0023] The upper spring body 11 is located between the inner rear end face of the handle 2 and the rear end face of the front fixing seat 10, while the lower spring body 11 is located between the inner front end face of the handle 2 and the front end face of the rear fixing seat 10.

[0024] The front and rear ends of the handle 2 are provided with grooves 14, and the front and rear ends of the two sets of guide posts 15 are inlaid with bearing seats 13. The grooves 14 serve to inlay the bearing seats 13, which are inlaid inside the grooves 14 and serve to fix the guide posts 15.

[0025] During operation, the gripper cylinder 6 connected to the robot moves to the vicinity of the handle 2. Under the action of the gripper cylinder 6, the jaw 8 closes and clamps the two sets of plug-in plates 5. At this time, the jaw 8 is inserted into the second connection hole 9 on the plug-in plate 5. Then, the jaw 8 continues to close, causing the pin 12 on the fixed seat 10 to retract. Subsequently, the robot inserts the combination of gripper cylinder 6, handle 2, and hydraulic cylinder 1 into the card seat 3. Then, under the action of the gripper cylinder 6, the jaw 8 opens and releases the two sets of plug-in plates 5. The pin 12 is pushed out under the action of the spring body 11 to insert into the first connection hole 4 on the card seat 3, locking the handle 2 and the card seat 3. Then, the jaw 8 on the gripper cylinder 6 continues to open, separating the gripper of the gripper cylinder 6, the jaw 8, the plug-in plate 5, and the second connection hole 9. Subsequently, the robot drives the gripper cylinder 6 to disengage from the plug-in plate 5. The hydraulic cylinder 1 and the card seat 3 are installed, and the pin 12 is inserted into the first connection hole 4, which prevents the hydraulic cylinder 1 from disengaging from the card seat 3, ensuring safety.
