Description
Technical Field
The utility model relates to a power actuator field, concretely relates to cylinder top cap device.
Background
In the automobile manufacturing process, in particular to a sheet metal welding tool clamp, compressed air is widely used as power to execute a mechanism for clamping and fixing. This device is a special cylinder, commonly called a gripper. In order to obtain stable clamping effect, a set of self-locking mechanism is arranged in the clamping device. Frequent opening and closing actions in the using process easily cause abrasion of the self-locking part, so that abraded accessories need to be replaced frequently, and the reliability and effectiveness of the device are ensured. In the existing cylinder, the part is installed in an internal groove and completely wrapped by a shell, a tool arranged outside the cylinder needs to be removed during replacement, the cylinder is detached, the shell is opened, a damaged accessory is taken out, a new accessory is installed, and then the cylinder is installed again. The process is complicated, the time is long, the tool clamp may need to be corrected again, and the continuous production of the automatic equipment is not facilitated.
In order to solve the above problems, we have made a series of improvements.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a cylinder top cover device to overcome the above-mentioned shortcoming and not enough that prior art exists.
A cylinder head assembly comprising: the top cover structure is connected with the top of the shell through the screw, the channel is arranged in the shell, accessories are arranged in the channel, the top cover structure is connected with the channel in a sealing mode, and the protruding portion of the lower portion of the top cover structure is connected with the accessories;
wherein, the roof structure includes: the top cover comprises a top cover body, a top cover convex block and a through hole, wherein the upper end of the top cover convex block is connected with the lower part of the top cover body, the lower end of the top cover convex block is connected with an accessory in a contact manner, the through hole is formed in the top cover body and is correspondingly connected with a screw, the through hole is a plurality of through holes, and the outside of the through hole is of a countersunk structure.
Furthermore, a threaded hole is formed in the shell.
The utility model has the advantages that:
the utility model discloses compare with the conventional art, replace current shell structure through addding top cap structure, realize only needing light demolising the top cap, just can change the accessory of damage, need not to demolish other parts, greatly reduce the installation, shorten down time, improve work efficiency, the top cap setting is outside at the casing simultaneously, isolated foreign matter, is applicable to the adverse circumstances operating mode that the welding slag splashes to the top cap outside is smooth and level, and visual effect is good, and the appearance is pleasing to the eye.
