Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tooling for engineering machinery, in particular to a novel tooling cylinder limiting device for engineering machinery. Background Art
[0002] The cylinder limit refers to the process of limiting the stroke range of the cylinder by setting certain mechanisms or components during the cylinder stroke, thereby ensuring the accurate, stable and reliable operation of the cylinder. In industrial production, the cylinder limit plays an important role. It can ensure that the cylinder operates within the normal working range and avoid equipment failure, production deformation and mechanical failure caused by overstroke. At the same time, it can also increase the safety and stability of the cylinder, improve the working efficiency and production quality of the equipment. Therefore, it is imperative to develop a cylinder limit structure that is both universal and flexible and has low cost. Although the cylinder limit under the existing technology can limit the stroke of the cylinder, it only limits the stroke distance and has poor versatility. The present application makes structural innovations on the basis of the original cylinder, which can make the cylinder limit more flexible and applicable to different cylinders.

[0005] A new type of engineering machinery tooling cylinder limit device includes a cylinder, a positioning long shaft, a threaded limit block, a mounting plate 1 and a mounting plate 2. One end of the cylinder is fixed on the mounting plate 2, and the cylinder shaft of the cylinder extends out of the mounting plate 2 and is fixedly connected to the mounting plate 1. The middle part of the positioning long shaft is provided with a threaded limit block, and its tail extends out of the mounting plate 2 and is fixedly connected to the mounting plate 1.
[0006] Preferably, the positioning long axis is fixed on the second mounting plate through a flange.
[0007] Preferably, the tail of the positioning long shaft is provided with a thread for fixed connection with a mounting plate.
[0008] Preferably, the flange is a long-neck flange, and the threaded limit block is connected to the long-neck flange.
[0009] Preferably, a push plate is provided at the top end of the cylinder shaft of the cylinder, and the push plate is fixedly connected to the mounting plate.
[0010] Preferably, guide rods are provided on both sides of the cylinder shaft of the cylinder, one end of the guide rod is fixedly connected to the push plate, and the other end extends out of the second mounting plate.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. The limit device of the utility model is adjustable, which can flexibly adjust the cylinder stroke, thereby significantly enhancing the adaptability of the cylinder during use; this design enables the same model of cylinder to meet the needs of more different application scenarios, greatly improving its practicality and economy;
[0013] 2. The utility model can solve the problem that fixed-stroke cylinders often cannot meet the tooling design requirements of different products, resulting in the company needing to purchase cylinders of various specifications to meet the needs of the production line. It can greatly reduce the types and quantities of cylinders that need to be purchased, thereby effectively reducing production costs and simplifying inventory management.
