Abstract
The invention relates to a sliding gear shifter structure of a feed box. The sliding gear shifter structure comprises a sliding gear, a shaft, a shifter, a location pin, an oil cylinder rod, a box body and an oil cylinder body; and the sliding gear is installed on the shaft, the shifter is fixed on the oil cylinder rod through the location pin, the oil cylinder body is installed on the box body, and the oil cylinder body and the oil cylinder rod form a telescopic oil cylinder structure. A shifter groove is formed on the shifter; and a sliding gear groove is formed on the sliding gear, and the shifter is clamped in the sliding gear groove. The function part of the shifter groove adopts a structure that a screw fastens a copper sheet, so that the wear resistance is increased, the location precision is ensured, and the service life is also prolonged; and additionally, after the abrasion, only the copper sheet needs to be changed, so that the use economy can be greatly improved.
Description
Technical field
The present invention relates to a kind of shifting fork structure, especially a kind of feed box shifting slide gear shifting fork structure belongs to the machinery industry field.
Background technique
In the machine tool feed case, engagement driving between the gear of the different numbers of teeth can realize different feed speeds, and the stationarity of engagement driving directly affects quality of processing between gear, and simultaneously transmission steadily also can not produce noise, affects service life of gear.So guarantee that the accuracy of gear engagement position is to seem very important.In the prior art, shifting fork structure is to adopt shift fork to stir shifting slide gear, realizes the engagement between gear, in this structure, through prolonged and repeated friction of stirring, cause shift fork face and face of gear serious wear, the Positioning Gear precise decreasing, make the gear engagement not in place, transmission process is not steady, produces noise, also affect simultaneously service life of gear, the shift fork also influential to quality of processing, that the shift fork after wearing and tearing in addition must be dismantled and more be renewed is realized Location accuracy.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of feed box shifting slide gear shifting fork structure simple in structure, ingenious, rational is provided, this structure can effectively solve between gear and mesh, in the long-term inaccurate problem of wearing and tearing backgear Location accuracy of using.
According to technological scheme provided by the invention: a kind of feed box shifting slide gear shifting fork structure comprises shifting slide gear, axle, shift fork, locating stud, cylinder rod, casing and cylinder body; Described shifting slide gear is installed on the axle, and shift fork is fixed on the cylinder rod by locating stud, and cylinder body is installed on the casing, and cylinder body and cylinder rod form the telescopic oil cylinder structure.
As a further improvement on the present invention, described shift fork is provided with fork slot; Shifting slide gear is provided with the shifting slide gear groove, and described fork slot is stuck in the shifting slide gear groove.
As a further improvement on the present invention, use the screw fastening copper sheet on two of described fork slot acting surfaces; Copper sheet thickness is determined according to reality.
The present invention compared with prior art, advantage is: screw fastening copper sheet structure is adopted at the fork slot position of working, and has increased wear resistance, guaranteed Location accuracy, also prolonged working life, in addition, after the wearing and tearing, only with the copper sheet of changing wearing and tearing, greatly improved its usage economy.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1, a kind of feed box shifting slide gear shifting fork structure comprises shifting slide gear 1, axle 2, copper sheet 3, screw 4, shift fork 5, locating stud 6, cylinder rod 7, casing 8, cylinder body 9.
The present invention adopts shifting slide gear 1 to be installed on the axle 2, shift fork 5 acting surfaces screw 4 fastening copper sheets 3, and described shift fork 5 is provided with fork slot; Shifting slide gear 1 is provided with shifting slide gear 1 groove, and described fork slot is stuck in the shifting slide gear groove.Shift fork 5 is fixed on the cylinder rod 7 by locating stud 6, and cylinder body 9 is installed on the casing 8, and cylinder rod 7 consists of the telescopic oil cylinder structure with cylinder body 9.
For keeping accurate positioning, copper sheet 3 thickness can arrange flexibly among the present invention.Screw fastening copper sheet structure is adopted at the fork slot position of working, and has increased wear resistance, has guaranteed Location accuracy, has prolonged working life, and can greatly improve its usage economy.
