Abstract
The invention discloses an adjustable self-centering tool false shaft which comprises a connection rod and supports. The supports are symmetrically arranged at the two ends of the connection rod and are cylinders. Each support comprises supporting rods, an adjusting nut, a rotary plate and a shaft sleeve, wherein the supporting rods are evenly distributed on the side wall of the support, and the rotary plate is disposed in the support; a planar thread structure is arranged on the back side of the rotary plate, and the back side of the rotary plate is parallel to the end face of the support; the adjusting nut is engaged with the rotary plate through a conical gear, and the adjusting nut is arranged on the side wall of the support; the supporting rods are in threaded connection with the back side of the rotary plate, and the shaft sleeve is arranged on the end face of the support. Threads are disposed at the two ends of the connection rod, the threads at the two ends of the connection rod are opposite structures, and the connection rod is in threaded connection with the shaft sleeve. The adjustable self-centering tool false shaft is high in adaptability and utilization rate, large in adjustment range, high in positioning precision and convenient to operate, and the manufacturing cost of the false shaft is greatly lowered.
Description
Technical field
The present invention relates to a kind of frock dummy shaft, particularly relating to one can self-centering frock dummy shaft.
Background technology
In Automatic manual transmission, a lot of link can relate to assembling axiality.For ensureing axiality requirement, in component of machine assembling, steel construction industry otic placode assembling, weld a lot of situation under dummy shaft all can be used as frock, both ensure that assembly precision, turn improved efficiency of assembling.But existing dummy shaft dimensions is just fixed up after processing, the diameter of dummy shaft depends on axis hole size, the length of dummy shaft depends on spacing between otic placode, if axis hole specification is many, the change of otic placode spacing greatly, then needs the dummy shaft manufacturing a lot of specification.Especially for the product not being batch production, not only utilization rate is very low for the dummy shaft of a large amount of different size, meanwhile, also significantly increases production cost.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind ofly can carry out according to axis hole specification and otic placode spacing the frock dummy shaft that regulates.
In order to solve the problems of the technologies described above, adjustable self-centering frock dummy shaft of the present invention, comprise connecting rod, bearing, described bearing is symmetricly set on the two ends of connecting rod, described bearing is cylinder, described bearing comprises strut, adjusting nut, rotating disk, axle sleeve, described strut is uniformly distributed in bearing sidewall, described rotating disk is arranged at bearing inside, the back side of described rotating disk is provided with flat thread structure, the back side of described rotating disk is parallel with seat end surface, described adjusting nut and described rotating disk are that angular wheel engages, described adjusting nut is arranged at bearing sidewall, described strut is threaded with the back side of described rotating disk, described axle sleeve is arranged at seat end surface, described connecting rod two ends are provided with screw thread, the screw thread at described connecting rod two ends is reverse geometry, described connecting rod is connected with sleeve thread.
First rotate adjusting nut during use, adjusting nut drives dial rotation, and driven by rotary disc strut moves as synchronization telescope, and strut withstands on the axle hole inner circle week of the components such as otic placode, realizes bearing automatically concentric with axis hole, and can adapt to the change in axis hole aperture well; Pivot link, thus drivening rod two end bearing moves axially, and realizes the adaptation of dummy shaft length and otic placode spacing.
The further improvement project of technique scheme, also comprises rotary handle, and described rotary handle is arranged on connecting rod, is preferably arranged at the middle part of connecting rod, easily can be realized the rotation of connecting rod by rotary handle.
The further improvement project of technique scheme, described strut is in 120 degree of distributions on bearing sidewall, and namely each bearing is provided with 3 struts.Also 4 struts can be set on each pedestal, in 90 degree of distributions on bearing sidewall.Described strut the best adopts strip, and the strut face of shoring is the face of cylinder, and strut and axle hole inner circle face form linear contact lay, thus guarantees aliging of dummy shaft axis and axis hole axis.
The more existing fixed frock dummy shaft of adjustable self-centering frock dummy shaft of the present invention, can regulate with component axis hole varying aperture, can meet the axis hole location of certain size scope; Strut synchronous can be realized stretch, automatically realize aliging of dummy shaft axis and axis hole axis; Can regulate with otic placode spacing, the otic placode assembling and positioning of certain size scope can be met.In general, adjustable self-centering frock dummy shaft strong adaptability of the present invention, utilization rate is high, adjustable range is large, positioning precision is high, easy to operate, greatly reduce dummy shaft manufacturing cost.

Detailed description of the invention
Structure Figure is described in detail adjustable self-centering frock dummy shaft of the present invention below.
Composition graphs 1 to 3 is known, and a kind of adjustable self-centering frock dummy shaft, comprise connecting rod 4, rotary handle 5, cylinder bearing 1, described rotary handle 5 is arranged on the middle part of connecting rod 4, and described cylinder bearing 1 is symmetricly set on the two ends of connecting rod 4.
Described cylinder bearing 1 comprises 3 bar shaped struts 2, described bar shaped strut 2 and is uniformly distributed in 120 degree on the sidewall of cylinder bearing 1.The face of shoring 10 of described strut 2 is the face of cylinder.
It is inner that described cylinder bearing 1 also comprises adjusting nut 3, rotating disk 6, described rotating disk 6 is arranged at cylinder bearing 1, the back side of described rotating disk 6 is provided with flat thread knot 9, the back side of described rotating disk 6 is parallel with the end face of cylinder bearing 1, and described rotating disk 6 can realize in the inside of cylinder bearing 1 rotating.Described adjusting nut 3 and the side of described rotating disk 6 are that angular wheel engages, and described adjusting nut 3 is arranged on the sidewall of cylinder bearing 1.The end face of described strut 2 is threaded with the back side of described rotating disk 6.
Described cylinder bearing 1 also comprises axle sleeve 11, and described axle sleeve 11 is arranged on the end face of cylinder bearing 1, and described connecting rod 4 two ends are respectively arranged with MF, and the axle sleeve 11 on described cylinder bearing 1 mates with the screw thread at connecting rod 4 two ends respectively and is connected.Connecting rod 4 can adopt hollow-core construction, and the MF at connecting rod 4 two ends can adopt external thread structure also can adopt female thread structure.
As shown in Figure 4, adjusting nut 3 is first rotated during use, adjusting nut 3 drives rotating disk 6 to rotate, thus driving strut 2 to move as synchronization telescope, strut 2 withstood on the axle hole inner circle week of otic placode A7 and otic placode B8, and the cylinder bearing 1 realizing connecting rod two ends is automatically concentric with the axis hole of otic placode A7 and otic placode B8 respectively, rotate rotary handle 5, drivening rod 4 rotates, thus drives two terminal circle cylinder bearing 1 to move axially, and realizes the adaptation of dummy shaft length and otic placode A7 and otic placode B8 spacing.
