Abstract
The utility model relates to a press-mounting clamp, particularly to a hydraulic balance press-mounting clamp capable of press mounting multiple bolts to be in place once. The hydraulic balance press-mounting clamp comprises an upper die base plate and a lower die base plate, wherein an oil cylinder mounting block fastened with the lower end of the upper die base plate is arranged at the lower end of the upper die base plate; more than one group of hydraulic dynamic mechanism is arranged in the oil cylinder mounting block and comprises a high-pressure single-acting oil cylinder, a balance oil path, a sealing ring and a pressure head; the balanced oil path is arranged in the oil cylinder mounting block and communicated with the high-pressure single-acting oil cylinder; the sealing ring is arranged between the balance oil path and the upper die base plate; the pressure head is arranged at the head part of the high-pressure single-acting oil cylinder; a lower positioning disk fastened with the upper end of the lower die base plate is arranged at the upper end of the lower die base plate; and bolt holes are formed on the lower positioning disk and correspond to the hydraulic dynamic mechanisms. The hydraulic balance press-mounting clamp has a relatively-simple structure; and the mounting precision is improved, the quality of products is improved and the operation is simplified.
Description
Technical field
The utility model is a kind of pressing clamp, particularly a kind of hydro-cushion pressing clamp that many bolts once can be press-fit into place.
Background technology
When brake system of car in the prior art assembles, the workpiece that need press-fit many bolts is very general, and generally all between 4-10, the height tolerance of workpiece press mounting hole is about ± 0.2mm, the bolt tail length tolerance about ± 0.3mm, accumulated tolerance is ± 0.5mm about.For above-mentioned reasons, the also assembling and pressing anchor clamps of useful spring balancing, but because of reasons such as the magnitude of interference between the workpiece differ, the difficult definite elastic force fatigue with control, spring of balancing spring power is fast, indivedual bolts often occur and be not pressed onto shortcomings such as position and workpiece abnormal deformation, product quality and anchor clamps can not be reached a standard service life.To design once before the utility model and be press-fit into place, and guarantee the not unusual difficulty of anchor clamps of abnormal deformation of the workpiece that puts in place earlier.So many before with single technology that press-fits, existing problems are operating efficiencies, press-fit the shortcomings such as bolt position degree instability of product.
Chinese patent CN200820025258.7 discloses a kind of automobile brake disc bolt press-loading apparatus, comprises floating platen; It is in the pilot hole that described floating platen is provided with, and is provided with the two ends end face of back-moving spring, places the positioning and guiding cover end face elasticity in its hole to join with pilot hole inner face and slip respectively; Connecting screw rod runs through positioning and guiding cover mesopore and back-moving spring mesopore and floating platen and is connected; Be provided with on the floating platen end face of pilot hole, be spacing at least and be provided with 3 pressure heads.By on floating platen, being connected with positioning and guiding cover and a plurality of pressure head, on having realized on single press device automobile brake disc a plurality of tighten up to press-fit in hole and a plurality of bolt cylindrical be connected.This structure is traditional mechanical type press mounting tool, and it is low to press-fit precision, causes product quality relatively poor relatively.
Summary of the invention
Utility model mainly is to solve the deficiencies in the prior art, and the tolerance that a kind of while can also relax workpiece counterbore height and bolt tail length is provided, and reduces the hydro-cushion pressing clamp of the manufacturing cost of workpiece.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of hydro-cushion pressing clamp, comprise baffle plate and following baffle plate, described lower end of going up baffle plate is provided with the oil cylinder mounting blocks that is fastened with it, be provided with one group of above hydraulic pressure in the described oil cylinder mounting blocks and press mechanism, described hydraulic pressure presses mechanism and comprises the high pressure single-acting cylinder, the balance oil circuit, sealing ring and pressure head, be provided with the balance oil circuit in the described oil cylinder mounting blocks, described balance oil circuit is connected with the high pressure single-acting cylinder, be provided with sealing ring between described balance oil circuit and last baffle plate, the head of high pressure single-acting cylinder is provided with pressure head, the described upper end of baffle plate down is provided with the following positioning disk that is fastened with it, be provided with bolt hole in the positioning disk under described, described hydraulic pressure presses the corresponding distribution with bolt hole of mechanism.
Be assemblied on the oil cylinder mounting blocks with a plurality of high pressure single-acting cylinders, will act on oil circuit with inside and outside two " O " shape sealing rings and be enclosed in together, and in closing oil path, pour the hydraulic pressure oil mass that makes oil cylinder reach 1/2 stroke.Mainly be to utilize the balanced characteristic of transmitting pressure of hydraulic pressure energy, realize pressing the mutual pressure balanced function of ram pressures on the anchor clamps.
Operation principle, when outside press drive patrix press-fits downwards, because the accumulated tolerance between the workpiece, the height that press-fits is different, the phenomenon that successively is press-fit into place is necessarily arranged, be press-fit into place the so earlier reaction force at pressure head place is bound to greater than the pressure head that does not put in place, and the big pressure head of reaction force is by the mode of moving back that contracts; Use in-oil cylinder hydraulic oil to the reaction force small oil tank direction transmission that do not put in place; When making anchor clamps continue to press down; The pressure head that has put in place does not press down pressing down or slow down, and the pressure head that other does not put in place continues to press down, and has so just guaranteed not abnormal deformation of the workpiece that puts in place earlier, simultaneously every bolt all is pressed onto the position.
As preferably, be with the pressure head duct ring in the described pressure head, described pressure head duct ring and oil cylinder mounting blocks fix.
As preferably, the cross section of described balance oil circuit is " worker " word shape, describedly goes up baffle plate and the oil cylinder mounting blocks fixes by bolt.
Therefore, the hydro-cushion pressing clamp that the utility model provides, structure is simple relatively, improves the precision of installing, and promotes the quality of product, has simplified operation simultaneously.
