Abstract
The invention discloses a taper hole barreling machine which comprises a taper mandrel (1). The middle of the taper mandrel (1) is larger than two ends of the taper mandrel (1), a bearing (7) is disposed in the middle of the taper mandrel (1), a rolling needle bush (3) is arranged on a section of the taper mandrel (1), and a rolling needle (6) is disposed on the rolling needle bush (3). The taper hole barreling machine is used for machining taper holes, machining level can be improved, roughness of the taper holes is low and can achieve 3.2 micrometers, and accordingly steering knuckles can be produced on a large scale. In addition, the taper hole barreling machine is simple in structure, parts are machined easily, and a plurality of taper barreling machines with different sizes can be manufactured, so that machining requirements of different types of steering knuckles are met.
Description
Technical field
The present invention relates to the engineering goods manufacture field, be specifically related to a kind of taper hole tumbling device that taper hole is processed.
Background technology
In the production field of knuckle and knuckle arm, it is 3.2 μ m that the taper hole roughness that knuckle matches with knuckle arm requires, and common tapering reamer processing can not reach such quality requirement, and can't realize large batch of production.
Summary of the invention
The present invention has overcome the deficiency of prior art, provides a kind of machining accuracy higher taper hole tumbling device.
For solving above-mentioned technical problem, the present invention adopts following technical scheme:
A kind of taper hole tumbling device comprises the tapering axle, and the middle part of said tapering axle is greater than two ends, and said tapering axle middle part is provided with bearing, and one section of said tapering axle is provided with needle bush, and said needle bush is provided with needle roller.
In order to realize the present invention better, further technical scheme is:
As preferably: be provided with first packing ring between above-mentioned needle bush and the bearing.
As preferably: above-mentioned tapering axle is provided with nut, and said nut is positioned at the end of tapering axle, and is connected with needle bush through second packing ring.
The present invention can also be:
As preferably: above-mentioned tapering axle is provided with boss.
Compared with prior art, one of beneficial effect of the present invention is:
Through improving level of processing with taper hole tumbling device processing taper hole of the present invention, make the taper hole roughness littler, make the taper hole roughness can reach 3.2 μ m, thereby can realize the production in enormous quantities of knuckle.And this taper hole tumbling device is simple in structure, and parts are processed easily, can make the tapering tumbling device of many cover different sizes, to satisfy the processing request of different model knuckle.
Description of drawings
Fig. 1 shows the structural representation of taper hole tumbling device according to an embodiment of the invention.
Wherein, the pairing name of the Reference numeral in the accompanying drawing is called:
1-tapering axle, 2-first packing ring, 3-needle bush, 4-nut, 5-second packing ring, 6-needle roller, 7-bearing, 8-boss.
The specific embodiment
Below in conjunction with embodiment the present invention is done to specify further, but embodiment of the present invention is not limited thereto.
Fig. 1 shows a kind of according to an embodiment of the invention schematic structure of taper hole tumbling device.Taper hole tumbling device as shown in Figure 1 comprises tapering axle 1, bearing 7, needle bush 3 and needle roller 6.With reference to the embodiment of figure 1, the middle part of said tapering axle 1 is greater than two ends, and said tapering axle 1 middle part is provided with bearing 7, and one section of said tapering axle 1 is provided with needle bush 3, and said needle bush 3 is provided with needle roller 6.Taper hole tumbling device according to embodiment illustrated in fig. 1 is used to process the taper hole that knuckle matches with knuckle arm, can improve level of processing with this taper hole tumbling device processing taper hole, makes the taper hole roughness littler.
Continue according to one embodiment of present invention, also to be provided with first packing ring 2 between above-mentioned needle bush 3 and the bearing 7 with reference to shown in Figure 1.According to another embodiment of the present invention, above-mentioned tapering axle 1 is provided with nut 4, and said nut 4 is positioned at the end of tapering axle 1, and is connected with needle bush 3 through second packing ring 5.According to another embodiment of the present invention, above-mentioned tapering axle 1 is provided with boss 8.
Particularly, the preferred Φ in the preferred M12 of nut * 1.25, the preferred 12-A140 of packing ring, needle roller 5 * 50, bearing preferred 8105.
Such scheme in use, the tapering axle of taper hole tumbling device is handled main shaft needle roller contact with taper hole with after the main shaft mohs tapered bore of vertical drill Z535 cooperates, adjusting the speed of mainshaft is 530 rev/mins, feed is 0.11 millimeter/commentaries on classics.Start lathe 1: 8 taper hole thick, that finish reamed is carried out tumbling, the tumbling of range estimation hole wall stops to roughness 3.2 μ m and after reaching the requirement of feeler gauge unevenness degree.
Can find out from above-described embodiment; The present invention adopts unique design and connected mode to improve the machining accuracy of taper hole tumbling device; Make the taper hole roughness reach 3.2 μ m, and this taper hole tumbling device is simple in structure, parts are processed easily; Can make the tapering tumbling device of many cover different sizes, to satisfy the processing request of different model knuckle.
" embodiment " who is spoken of in this manual, " another embodiment ", " embodiment ", etc., refer to the concrete characteristic, structure or the characteristics that combine this embodiment to describe and be included among at least one embodiment that the application's generality describes.A plurality of local appearance statement of the same race is not necessarily to refer to same embodiment in specification.Further, when describing a concrete characteristic, structure or characteristics in conjunction with arbitrary embodiment, what institute will advocate is that other embodiment of combination realize that this characteristic, structure or characteristics also fall within the scope of the invention.
Although invention has been described with reference to a plurality of explanatory embodiment of the present invention here; But; Should be appreciated that those skilled in the art can design a lot of other modification and embodiments, these are revised and embodiment will drop within disclosed principle scope of the application and the spirit.More particularly, in the scope of, accompanying drawing open and claim, can carry out multiple modification and improvement to the building block and/or the layout of subject combination layout in the application.Except modification that building block and/or layout are carried out with improve, to those skilled in the art, other purposes also will be tangible.
