Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the utility model provides an upper cover for going up compression cylinder, include the lid 1 of being connected with cylinder 16, lid 1 center is provided with linkage segment 2, the outside of linkage segment 2 is provided with external screw thread 15, the setting of linkage segment 2 and external screw thread 15 is used for with 16 threaded connection of cylinder. An oil inlet 4 is formed in one side of the cover body 1, and the oil inlet 4 is communicated with a communicating hole 3 formed in the inner side of the connecting section 2 through an oil way in the cover body 1. Fixing threaded holes 13 are uniformly distributed on the periphery of the connecting section 2, the fixing threaded holes 13 are connected with pull rods 17 through bolts, and then the upper cover is fixedly connected with a lower cover 18 arranged at the bottom of the oil cylinder through the pull rods 17. The four corners of the cover body 1 are provided with assembling threaded holes 14, and the assembling threaded holes 14 are used for fixing the upper cover on the workbench.

The cover body 1 is provided with fixing assemblies on two sides, and the fixing assemblies are used for clamping the cylinder barrel 16 and preventing the upper cover and the cylinder barrel 16 from being loosened easily. Fixed subassembly is including setting up fixed block 5 on lid 1, through-hole 6 has been seted up on fixed block 5, sliding connection has slider 7 in the through-hole 6, the outer end of slider 7 is connected with stopper 8, stopper 8's size is greater than the size of through-hole 6, and this kind of setting can prevent that slider 7 from slipping out in the through-hole 6. Be provided with first screw hole 11 on the stopper 8, be provided with second screw hole 12 on the fixed block 5, first screw hole 11 is coaxial with second screw hole 12, the setting of first screw hole 11 and second screw hole 12 can be fixed stopper 8 and fixed block 5 through the screw rod. The inner of slider 7 is connected with arc piece 9, the setting of arc piece 9 is used for the chucking cylinder, prevents that the threaded connection between cylinder and the upper cover is not hard up. The anti-skidding mechanism is characterized in that anti-skidding teeth 10 are uniformly distributed on the inner side of the arc-shaped block 9, the anti-skidding teeth 10 are made of soft materials such as soft rubber, and the anti-skidding teeth 10 are arranged to increase the friction force between the arc-shaped block 9 and the cylinder barrel and increase the clamping force of the arc-shaped block 9. When the inner side of the limiting block 8 is tightly attached to the outer side of the fixing block 5, the anti-skid teeth 10 are tightly attached to the outer side of the cylinder barrel.
