Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic welding, and specifically relates to a cylinder-type quick-opening cover structure for use in ultrasonic welding equipment. Background Technology

[0002] The acoustic system of ultrasonic welding equipment includes a transducer and an amplitude transformer, which are assembled together and mounted on an acoustic system mounting frame via an amplitude transformer mounting bracket. An outer casing is typically installed around the acoustic system to protect it; the transducer can only be inspected and replaced after the casing is opened. However, in existing ultrasonic welding equipment, the outer casing is usually bolted to the frame. Removing and installing the casing requires tightening screws, which is inconvenient and affects the efficiency of transducer inspection and replacement. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide a cylinder-type quick-opening cover structure that can quickly open the outer cover of the acoustic system of an ultrasonic welding equipment, thereby improving the efficiency of transducer maintenance and replacement.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] This utility model provides a cylinder-type quick-opening cap structure, including:

[0006] frame;

[0007] Acoustic systems;

[0008] An outer cover, which is disposed outside the acoustic system;

[0009] The lid opening mechanism includes:

[0010] First connector for connecting the rack;

[0011] A second connector for connecting the outer cover;

[0012] One or more linkage assemblies, wherein one end of the linkage assembly is rotatably connected to a first connector and the other end is rotatably connected to a second connector;

[0013] A cylinder-type elastic element, one end of which is rotatably connected to a first connecting member, and the other end of which is rotatably connected to an outer cover.

[0014] Furthermore, the connecting rod assembly includes a crank-connecting rod, with bearings and connecting shafts at both ends. Shaft holes are formed at both ends of the crank-connecting rod. Fixing holes are formed on both the first and second connecting members. The bearings are sleeved on the connecting shaft and positioned between the shaft hole and the fixing hole. The connecting shaft is damped and rotatably connected to the shaft hole and fixedly connected to the fixing hole. This structural configuration allows for damped rotatable connections between the two ends of the crank-connecting rod and the first and second connecting members, respectively. Rotation enables relative movement between the outer casing and the frame, allowing for the opening and closing of the outer casing. During opening and closing, the outer casing can be suspended at a certain angle due to damping, facilitating transducer maintenance and replacement.

[0015] Furthermore, the crank connecting rod includes a first rod body and a second rod body. One end of the first rod body and one end of the second rod body are connected to form a "zigzag" shaped structure. The shaft hole is located at the end of the first rod body away from the second rod body and at the end of the second rod body away from the first rod body. In this application, setting the crank connecting rod into a "zigzag" shaped structure makes the rotation at both ends smoother.

[0016] Furthermore, the crank connecting rod includes a first rod body, a second rod body, a third rod body, a fourth rod body, a fifth rod body, and a sixth rod body. The first rod body, the second rod body, the third rod body, the fourth rod body, the fifth rod body, and the sixth rod body are connected sequentially. The first rod body and the third rod body are perpendicular to the second rod body, and the first rod body and the third rod body are parallel. The first rod body and the second rod body are connected to form an "L"-shaped first limiting groove, which is used to limit the end where the fixing hole of the second connector is located. The third rod body and the fourth rod body are connected to form a "zigzag" shaped structure. The fourth rod body and the sixth rod body are perpendicular to the fifth rod body, and the fourth rod body and the sixth rod body are parallel. The shaft hole is opened at the end of the first rod body away from the second rod body and at the end of the sixth rod body away from the fifth rod body. The fifth rod body and the sixth rod body are connected to form an "L"-shaped second limiting groove, which is used to limit the end where the fixing hole of the first connector is located.

[0017] Furthermore, the connecting shaft includes a threaded connection portion, a rotating connection portion, and a limiting portion. The threaded connection portion is connected to the limiting portion via the rotating connection portion. The fixing hole is a threaded hole, and the threaded connection portion is connected within the threaded hole. The bearing is sleeved on the rotating connection portion, and the rotating connection portion is damped and rotatably connected to the shaft hole. One end of the limiting portion near the rotating connection portion abuts against the side of the crank connecting rod. This structure enables both the rotating connection between the connecting shaft and the crank connecting rod, and the fixed connection between the connecting shaft and the first and second connecting parts. It also allows the limiting portion to limit the crank connecting rod, thereby improving the structural stability of the connecting rod assembly.

[0018] Furthermore, the linkage assembly is provided in four sets, and the four sets of linkage assemblies are parallel to each other; the first connector includes a support plate and two vertically parallel connecting rods, the two connecting rods are integrally connected to the left and right sides of the support plate, and the upper and lower ends of the two connecting rods are provided with the fixing holes; there are two second connectors, the two second connectors are respectively arranged one-to-one with the two connecting rods, and the upper and lower ends of the two second connectors are provided with the fixing holes, so that the first connector and the second connector each include four vertically arranged fixing holes, which are respectively connected to the four sets of linkage assemblies.

[0020] Furthermore, a position sensor is provided on the support plate, and one set of the connecting rod assemblies includes a sensing plate corresponding to the position sensor, the sensing plate being rotatably connected to the rotating connection part. The position sensor can cooperate with the sensing plate to sense the rotation angle of the connecting rod assembly, preventing the connecting assembly from rotating excessively.

[0021] Furthermore, the cylinder-type elastic element includes an air spring. A first rotating seat is provided on the outer wall of the support plate, and a second rotating seat is provided on the inner wall of the outer cover. The air spring includes a spring cylinder, a telescopic shaft, and a fixed shaft. The spring cylinder has a cylinder cavity.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] To achieve the above objectives, the technical solution of this utility model is as follows:

This structure enables both the rotating connection between the connecting shaft 433 and the crank connecting rod 431, and the fixed connection between the connecting shaft 433 and the first connecting member 41 and the second connecting member 42. Furthermore, the limiting portion 4333 can limit the crank connecting rod 431, thereby improving the structural stability of the connecting rod assembly 43.
