In order to overcome the shortcomings of the prior art, the utility model provides a combined ram droop compensation device, which adopts the integral combined design, has compact and simple structure and reliable effect.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a modular ram flagging compensation arrangement, is including setting up annex straining device and the flagging compensation arrangement of ram in the ram, annex draws near device one end and is connected with the jam, and annex straining device is equipped with the spacer sleeve outward with the jam, and the flagging compensation arrangement of ram includes pull rod, plug subassembly and gland, plug rod one end is connected with pull rod one end, and the pull rod other end is connected with the jam, and plug rod overcoat is equipped with the plug subassembly, and the plug subassembly includes plug, fender ring and cylinder liner, the plug passes through fender ring and plug rod fixed connection, and the cylinder liner cover is established outside the plug, is equipped with the oil inlet on the cylinder liner, and the gland cover is established at the tip of plug rod.
In the above technical solution, the number of the sliding plug assemblies is one or more groups.
In the technical scheme, the spacer bush is in a circular truncated cone shape, and the circular truncated cone is used for being in contact with the ram to achieve tensioning.
In the technical scheme, sealing rings are arranged between the sliding plug and the sliding plug rod and between the sliding plug and the cylinder sleeve.
In the above technical scheme, the gland is fixedly connected with the sliding plug rod through the fastening nut.
In the technical scheme, both ends of the pull rod are connected with the plug and the sliding plug rod through threads.
In the technical scheme, communicated pore channels are arranged at the center of the sliding plug rod, the pull rod and the plug.
The utility model has the advantages that: the whole combined type design is adopted, the structure is simple and compact, the adjustment and the installation are convenient, the pre-tightening is reliable, and the pre-tightening force can be adjusted through the number of the sliding plug assemblies or the pressure of hydraulic oil.

Fig. 1 is a schematic sectional view of the present invention.
Wherein: 1. accessory tensioning device, 2, spacer bush, 3, plug, 4, pull rod, 5, sliding plug rod, 6, sliding plug, 7, baffle ring, 8, cylinder sleeve, 8.1, oil inlet, 9, gland, 10, sealing ring, 11, fastening nut, 12 and ram.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
A modular ram droop compensation device as shown in fig. 1, including setting up annex straining device 1 and the ram droop compensation device in ram 12, annex draw-in device 1 one end is connected with and blocks up 3, and annex straining device 1 and 3 are equipped with spacer 2 outward, and ram droop compensation device includes pull rod 4, sliding plug pole 5, sliding plug subassembly and gland 9, sliding plug pole 5 one end is connected with pull rod 4 one end, and the pull rod 4 other end is connected with and blocks up 3, and sliding plug pole 5 overcoat is equipped with the sliding plug subassembly, and the sliding plug subassembly includes sliding plug 6, fender ring 7 and cylinder liner 8, sliding plug 6 passes through fender ring 7 and sliding plug pole 5 fixed connection, and 8 covers of cylinder liner are established outside sliding plug 6, are equipped with oil inlet 8.1 on the cylinder liner 8, and 9 covers the tip at sliding plug pole 5.
In the above technical solution, the number of the sliding plug assemblies is one or more groups; when the sliding plug assemblies are multiple groups, the sliding plug assemblies are all sleeved outside the sliding plug rod 5. The multiple sets of sliding plug assemblies can generate larger pulling force when hydraulic oil pressure is fixed.
In the technical scheme, the spacer bush 2 is in a circular truncated cone shape, and the circular truncated cone is used for being in contact with the ram to achieve tensioning.
In the technical scheme, sealing rings 10 are arranged between the sliding plug and the sliding plug rod 6 and between the sliding plug 6 and the cylinder sleeve 8.
In the above technical solution, the gland 9 is fixedly connected with the sliding plug rod through the fastening nut 11.
In the technical scheme, two ends of the pull rod 4 are connected with the plug 3 and the sliding plug rod 5 through threads.
In the technical scheme, the centers of the sliding plug rod 5, the pull rod 4 and the plug 3 are provided with communicated pore channels.
The whole compensation device is arranged on the left side and the right side of the inner upper part of the ram 12, and initial pretightening force is provided by the fastening nut 11, so that the truncated cone-shaped end surface of the spacer bush 2 is tightly attached to the ram 12.
When the ram droop needs to be compensated, hydraulic oil is pumped into the ram through the oil inlet to enable the ram 6 to drive the ram rod 5 to move backwards, then the pull rod 4, the plug 3 and the spacer bush 2 are used, finally, the tensile force is applied to the ram 3 through the end face of the round table of the spacer bush, the ram droop is overcome, the change of the droop amount of the ram during operation can be adapted through the adjustment of the pressure of the oil cylinder or the number of the oil cylinders, the adjustment is simple, and the compensation effect is reliable.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
