Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, and in particular relates to a pneumatic top piece structure of a welding assembly clamp inspection tool. Background Art

[0002] When welding workpieces, different chucks are needed to accommodate a wider variety of workpieces. In addition, after the workpiece is welded, it is necessary to place it in a chuck with rigid fixing capabilities to prevent the workpiece from deforming after welding. At this time, the local temperature of the workpiece is high and it is difficult to remove it. The staff can only wait for the cooling to be completed before removing it, and the removal steps are complicated.

[0003] Patent application number CN103203573 is a pneumatic ejector mechanism of a welding fixture of a pneumatic ejector structure of a welding assembly fixture, including a cylinder, a mechanical valve, an air pipe, a bracket, an ejector plate, a first ejector rod, and a second ejector rod. The bracket is fixedly mounted on the welding fixture, the cylinder is fixed on the bracket, the air inlet and the air outlet of the cylinder are respectively connected to the mechanical valve through the air pipe, the mechanical valve controls the extension and contraction of the piston rod of the cylinder, the piston rod end of the cylinder is connected to the ejector plate, the first ejector rod and the second ejector rod are mounted on the ejector plate, and the bottom plate of the welding fixture is provided with a clearance hole for the first ejector rod and the second ejector rod to pass through, and the first ejector rod and the second ejector rod can move freely in the corresponding clearance hole. The above device can only eject the workpiece, and the removal efficiency is low when encountering a large workpiece, and the ejection of the workpiece is realized only by two ejector rods, which is easy to cause the workpiece to fall due to unstable fixation during operation. Therefore, it is urgent for technicians in this field to solve the above technical problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a pneumatic ejector structure of a welding assembly fixture in view of the deficiencies of the above-mentioned prior art. The pneumatic ejector structure of the welding assembly fixture drives the first ejector plate and the second ejector plate through a driving component, so as to achieve the purpose of ejecting a large workpiece from the welding assembly fixture.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A pneumatic ejector structure of a welding assembly fixture comprises a drive assembly, an ejector assembly and a support frame, wherein the drive assembly is used to provide power for the ejector assembly, and the ejector assembly is used to eject the workpiece and the chuck from the fixture; the drive assembly comprises a first drive cylinder, a second drive cylinder and a third drive cylinder, and the ejector assembly comprises a first ejector plate and a second ejector plate; the first drive cylinder is connected to the first ejector plate, the second drive cylinder and the third drive cylinder are connected to the second ejector plate, and the drive assembly and the ejector assembly are arranged in the support frame.

[0007] Furthermore, the first driving cylinder is arranged between the first driving cylinder and the second driving cylinder; the first driving cylinder is connected to the first ejection plate through a telescopic rod, and a ejector support is also arranged on the first ejection plate, and a total of four ejector supports are arranged.

[0008] Since the first driving cylinder is centrally arranged between the second driving cylinders, the force distribution of the entire ejection system can be better balanced, making the ejection action more stable and uniform, and preventing the workpiece from being deflected or deformed during the ejection process. The first ejection plate is connected by a telescopic rod, which can more accurately transmit the thrust of the cylinder, making the ejection action more precise and controllable, which is beneficial to improving the accuracy of the workpiece removal position. Four ejector pillars are arranged on the first ejection plate to form a stable four-point support structure, which can not only effectively disperse the ejection force and avoid local overload, but also improve the stability and reliability of the workpiece fixation, and prevent the workpiece from loosening or slipping in the fixture. The four ejector pillars can contact and support different parts of the workpiece in all directions, thereby providing all-round support during ejection, reducing the stress concentration on the workpiece, and protecting the workpiece from damage.

[0009] Furthermore, the second driving cylinder and the third driving cylinder are connected to the second ejection plate via a connecting member.

[0010] The double cylinder linkage can provide greater ejection force, especially for heavier or difficult to separate workpieces, to ensure that there is enough force to eject them safely and smoothly from the fixture. The connection angle and position of the second and third drive cylinders and the second ejector plate can be adjusted through the connecting parts to meet the requirements of ejection stroke and direction under various working conditions, thereby improving the flexibility and adaptability of the equipment. Two cylinders act on one ejector plate at the same time. Even if one of the cylinders fails, the other can continue to work, ensuring the continuity and stability of the equipment operation and reducing the risk of shutdown. This design helps to optimize the internal space utilization, simplify the pipeline layout, and improve the overall compactness of the structure.

[0011] Furthermore, two connecting members are provided, and both connecting members are provided in the supporting frame.

[0012] The two connectors are respectively connected to the second driving cylinder and the third driving cylinder to the second ejector plate, so that the power from the two cylinders can be evenly distributed to the second ejector plate, avoiding excessive force on a single point, thereby achieving load balance, improving the stability of the ejection action and extending the service life of the equipment. The double connector design enhances the connection strength and rigidity between the second ejector plate and the driving cylinder, ensuring that when the cylinder outputs high-pressure gas to generate a large thrust, the structure remains stable and reliable without deformation or breakage. The connector is arranged in the support frame, which can facilitate daily maintenance and overhaul. The component layout is compact, which is easy for operators to check and replace parts. It is also beneficial to keep the equipment clean and reduce the impact of the external environment on it. The internal connector is conducive to optimizing the spatial layout of the overall fixture, so that the structures of each part are closely matched and do not occupy too much external space, which is in line with the development trend of miniaturization and integration of modern industrial production equipment.

[0013] Furthermore, the driving assembly is fixed in the supporting frame by bolts.

[0014] The use of bolt fixing can form a firm mechanical connection between the drive assembly and the support frame, effectively preventing the drive assembly from shifting or loosening due to vibration, impact, etc. during use, thereby ensuring the stability of the entire pneumatic top piece structure. Bolt connection is a standard and convenient fixing method, which is convenient for quick disassembly and assembly operations during equipment assembly, commissioning, maintenance or replacement of parts, greatly improving work efficiency. According to needs, different specifications of bolts can be selected to adapt to different load requirements to ensure that the drive assembly can be fully and reliably fixed under various working conditions. The bolt connection method complies with the general standards of the machinery industry, which is not only convenient for procurement and spare parts management, but also convenient for coordination and docking with other standard interfaces, improving the overall compatibility and interchangeability of the equipment. Compared with other connection methods, bolt connection has higher advantages in load-bearing capacity and safety, and can effectively prevent safety accidents caused by connection failure and ensure the safety of the production process.

[0015] Furthermore, a fixing piece is also provided on the second ejection plate, and the fixing piece is connected to the second ejection plate by bolts.

[0016] The presence of the fixings can further enhance the structural stability of the second ejector plate, ensure that it maintains rigidity during the ejection of the workpiece, and prevent deformation or damage caused by uneven force. The fixings connected by bolts can be flexibly installed and positioned according to actual needs, and can be conveniently adjusted according to the shapes and sizes of different workpieces to achieve the best ejection effect and workpiece positioning accuracy. The fixings are independent of the second ejector plate and are connected by bolts, so that the component has good modular characteristics and is convenient for later maintenance, replacement and upgrading. The fixings are usually used to install auxiliary devices or directly contact the workpiece. They are fixed to the second ejector plate by bolts, which can effectively disperse the ejection force and improve the overall bearing capacity. When the production process or workpiece type changes, it is only necessary to adjust or replace the fixings to adapt to the new needs without significantly changing the entire ejector structure, which greatly improves the adaptability and service life of the equipment.

[0017] Furthermore, the second ejector plate is provided with a clearance opening, the fixing member is fixed above the clearance opening, and the first ejector plate is arranged in the clearance opening.

[0018] By setting a clearance port on the second ejector plate, the internal space can be reasonably utilized, so that the first ejector plate can move freely in a limited space, avoiding structural interference and improving the space utilization rate of the equipment. The design of the clearance port allows the first ejector plate to extend from the bottom when needed, and work with the fixing part to ensure the smoothness and accuracy of the ejection action and meet the ejection requirements of different workpieces. The fixing part is located above the clearance port, which can play a role of auxiliary support and positioning when the first ejector plate ejects the workpiece, which not only ensures the ejection force, but also avoids the shaking and tilting of the workpiece during the ejection process. The existence of the clearance port facilitates the inspection, cleaning and maintenance of the first ejector plate and its connecting parts, and makes the operation more convenient if replacement or repair is required.

[0019] The utility model has the following beneficial effects:

[0020] The utility model can quickly take out the cooled workpiece from the welding assembly fixture by means of the first ejector plate, and can quickly take out the overweight workpiece by the second ejector plate, and the ejector assembly is tightly combined with the drive assembly and installed together in the support frame, thereby ensuring the stability and rigidity of the overall structure, and ensuring the accuracy and safety during the ejection process. The first ejector plate and the second ejector plate cooperate with each other to realize the ejection of large workpieces, which greatly saves manpower compared to manually taking out the workpieces.

[0021] The second ejector plate can also be used to eject large workpieces, which improves the application range of the device. The first ejector plate is controlled by the first driving cylinder, and the second ejector plate is ejected by the second driving cylinder and the third driving cylinder. The first ejector plate and the second ejector plate can work simultaneously or in stages, and the control is more sophisticated.

[0022] The clearance opening on the second ejector plate can allow the first ejector plate to enter and exit, thereby avoiding affecting the operation of the second ejector plate. BRIEF DESCRIPTION OF THE DRAWINGS
