Description

Technical Field

[0001] This utility model belongs to the technical field of engine processing equipment, specifically relating to a two-hand gripper for transporting engine cylinder heads. Background Technology

[0002] With the rapid development of the automotive industry and the increasing demand for automobiles, car manufacturers need to continuously improve production efficiency to meet market demand. Currently, automobile production involves manufacturing different parts in different workshops, and then assembly workers assemble these parts together, forming a complete automobile production line. Therefore, to ensure the production efficiency of automobiles, it is essential to ensure the production efficiency of each individual component.

[0003] As the heart of a car, the engine's production is a crucial part of automobile manufacturing. However, manual handling between the various machines on the cylinder head processing line is labor-intensive, inefficient, and unsuitable for mass production. Conveying equipment, on the other hand, requires a large area and hinders efficient use of factory space.

[0004] To address the aforementioned problems, this application proposes a two-handed gripper for transporting engine cylinder heads. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a two-handed gripper for transporting engine cylinder heads, which features small space occupation and improved transport efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a two-hand gripper for conveying engine cylinder heads, wherein the two grippers are mounted on a robotic arm, and the two grippers include a connecting seat for mounting to the robotic arm. Two clamping cylinders are mounted on the connecting seat, and each clamping cylinder is provided with a pair of grippers forming a group. An opening for picking up and placing cylinder heads is formed at one end of the grippers away from the clamping cylinder and at the other end of the two groups of grippers facing away from each other. The two groups of clamping cylinders and grippers grasp the two cylinder heads back to back.

[0007] As a preferred technical solution of this utility model, a pressure holding valve is installed on one side of each clamping cylinder, and a position sensor for sensing the gripper to be in position is provided on the other side of the clamping cylinder.

[0008] As a preferred embodiment of this utility model, a bracket is fixed on one side of the connecting seat, and multiple position sensors are provided along the gripper clamping path and installed on the bracket.

[0009] As a preferred embodiment of this invention, the gripper is equipped with a plurality of sensing rods corresponding to the position sensor.

[0010] As a preferred technical solution of this utility model, the gripper includes a first abutment plate close to another set of grippers and a second abutment plate fixed inside the gripper and close to the clamping cylinder, and the cylinder cover is positioned in the gripper by the first abutment plate and the second abutment plate.

[0011] As a preferred embodiment of this utility model, a clamping plate is fixed on the inner side of the gripper to clamp the cylinder head.

[0012] Compared with the prior art, the beneficial effects of this utility model are: after the two grippers and the robotic arm are installed, they are controlled by the main control unit. The double-sided grippers can simultaneously move two cylinder heads, which is safer and more efficient than manual operation. It also avoids possible damage during cylinder head transportation and can accurately and quickly transfer workpieces between different devices, greatly improving work efficiency and meeting the needs of mass automated production.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] Please see Figures 1-6 This utility model provides the following technical solution: a two-hand gripper for conveying engine cylinder heads. The two grippers are mounted on a robotic arm 8. The two grippers include a connecting seat 1 that is mounted on the robotic arm 8. Two clamping cylinders 2 are mounted on the connecting seat 1. Each clamping cylinder 2 is provided with a pair of grippers 3. The grippers 3 are made of carbon steel and work with the ZIMMER high-strength clamping cylinders 2 to ensure structural strength and thus ensure gripping reliability. The end of the grippers 3 facing away from the clamping cylinder 2 and the other end of the two sets of grippers 3 facing away from each other have openings for picking up and putting down cylinder heads. The two sets of clamping cylinders 2 and grippers 3 grip the two cylinder heads facing away from each other.

[0024] Specifically, each clamping cylinder 2 is equipped with a pressure holding valve 4 on one side. The pressure holding valve 4 can prevent the cylinder cover from loosening or falling off during the transplanting process. The other side of the clamping cylinder 2 is equipped with a position sensor 6 for the induction gripper 3 to be in place.

[0025] Specifically, a bracket 5 is fixed on one side of the connecting seat 1, and multiple position sensors 6 are provided along the clamping path of the gripper 3 and installed on the bracket 5.

[0026] Specifically, the gripper 3 is equipped with multiple sensing rods 7 corresponding to the position sensors 6. The multiple position sensors 6 and sensing rods 7 can grip different models of cylinder heads. Each type of cylinder head corresponds to a set of position sensors 6 and sensing rods 7, which has higher adaptability and practicality.

[0027] Specifically, the gripper 3 includes a first abutment 31 close to another set of grippers 3 and a second abutment 33 fixed inside the gripper 3 and close to the clamping cylinder 2. The cylinder head is positioned in the gripper 3 by the first abutment 31 and the second abutment 33. The first abutment 31 and the second abutment 33 are both used for positioning the cylinder head when it enters, ensuring that the cylinder head is in place before gripping, thus ensuring stable transport.

[0028] Specifically, a clamping plate 32 is fixed on the inner side of the gripper 3 to clamp the cylinder head. The clamping plate 32 can be made of rubber and is installed on the inner side of the gripper 3 by bolts to increase the friction after gripping the cylinder head and reduce the wear on the cylinder head.

[0029] The working principle and usage process of this utility model are as follows: The gripper is installed on the robot arm 8 via the connecting seat 1. It is installed in the engine cylinder head production line between the loading and unloading stations of each piece of equipment. The pressure holding valve 4 and the bracket 5 are controlled by the control unit. The robot arm 8 moves the gripper to the loading and unloading station of the cylinder head. The first abutment plate 31 and the second abutment plate 33 abut against the two sides of the cylinder head. Then, the bracket 5 is activated to move the two symmetrical grippers 3 inward and clamp the cylinder head through the clamping plate 32. The cylinder head is then removed. Subsequently, the robot arm drives the gripper to rotate and clamp another cylinder head on the other side of the gripper. The cylinder head is then transported to the next loading station by the robot arm 8.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
