Abstract
The universal type auxiliary tool for installing the axle dust guard relates to the technical field of installation of axles of rail vehicles, and comprises a sleeve, a plurality of red copper partition plates, a plurality of connecting plates and a plurality of bolts, wherein a plurality of through holes are formed in the side wall of the sleeve, the red copper partition plates and the connecting plates are in one-to-one correspondence and are arranged in parallel along the axial direction of the sleeve, two ends of each red copper partition plate are respectively provided with a bulge, each bulge is provided with an internal thread hole along the radial direction of the sleeve, and each bulge is correspondingly inserted into one through hole; both ends of every connecting plate all are equipped with a screw hole, and a plurality of bolts one-to-one passes a plurality of screw holes and a plurality of internal thread hole back in order, links firmly a plurality of red copper baffles and a plurality of connecting plate together. The utility model is suitable for a dust guard assembly process of the not unidimensional axle journal of different motorcycle types, this frock dismouting is nimble, and repair cycle is short, and the commonality is high, shortens dust guard assembly cycle and frock repair cycle from essence by a wide margin, accords with the commonality and the integration requirement of frock.
Description
Technical Field
The utility model relates to a rail vehicle axletree installation technical field, concretely relates to auxiliary fixtures is used in installation of general type axletree dust guard.
Background
At present, the end parts of axles of high-speed motor train units, city railway vehicles and the like need to be provided with dust shields, namely, the dust shields are arranged on dust shield seats at the end parts of the axles in an interference fit manner. The existing installation mode is that a nylon sleeve for preventing the surface of an axle from being damaged is sleeved on the outer surface of the end part of the axle, and then the nylon sleeve is hammered by a hammer so as to sleeve the dust guard on a dust guard seat in an interference fit manner through the nylon sleeve, and then the installation of the dust guard is completed. Due to the fact that the axle journals of the axles are different in size, each axle with different sizes needs to be matched with a single nylon sleeve to install the dust guard, universality is avoided, and production cost is increased; on the other hand, after a certain service cycle, the nylon sleeve is large in abrasion, difficult to repair, long in repair cycle and easy to delay the production cycle.
SUMMERY OF THE UTILITY MODEL
The nylon sleeve that exists in order to solve does not have the commonality and leads to manufacturing cost high to and repair difficulty, restoration cycle length after the nylon sleeve wearing and tearing, cause production cycle to drag the technical problem who prolongs, the utility model provides a general type axletree dust guard installs and uses auxiliary fixtures.
The utility model provides a technical scheme as follows that technical problem took:
the universal type auxiliary tool for installing the axle dust guard comprises a sleeve, a plurality of red copper partition plates, a plurality of connecting plates and a plurality of bolts, wherein a plurality of through holes are formed in the side wall of the sleeve; both ends of every connecting plate all are equipped with a screw hole, and a plurality of bolts one-to-one passes a plurality of screw holes and a plurality of internal thread hole back in order, links firmly a plurality of red copper baffles and a plurality of connecting plate together.
The utility model discloses an auxiliary fixtures still includes two at least handles, and the handle is radially fixed on telescopic outer wall along the sleeve.
The utility model has the advantages that: this frock utilizes detachable red copper baffle both can prevent to gouge the axle journal, can make the frock cover on not unidimensional axle journal again, simultaneously in red copper baffle wearing and tearing back, only need maintain and change new red copper baffle, can accomplish the restoration of frock. Therefore, the tool is suitable for the assembly process of the dust guard plates of the shaft necks of different sizes of different vehicle types, is flexible to disassemble and assemble, short in repair period and high in universality, substantially shortens the assembly period of the dust guard plates and the repair period of the tool, and meets the requirements of the universality and the integration of the tool.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 to 4, the universal auxiliary tool for mounting the axle dust guard of the present invention comprises a sleeve 1, four red copper partition plates 2, four connecting plates 3, eight bolts 4 and two handles 5, wherein the handles 5 are radially fixed on the outer wall of the sleeve 1 along the sleeve 1; four pairs of through holes 1-1 which are vertically arranged are arranged on the side wall of the sleeve 1, four red copper partition plates 2 and four connecting plates 3 are arranged in parallel along the axial direction of the sleeve 1 in a one-to-one correspondence manner, two ends of each red copper partition plate 2 are provided with a bulge 2-1, each bulge 2-1 is provided with an internal thread hole along the radial direction of the sleeve 1, and each bulge 2-1 is correspondingly inserted into one through hole 1-1; both ends of every connecting plate 3 all are equipped with a screw hole, and eight bolts 4 one-to-one pass eight screw holes and eight internal thread holes in order after, link firmly four red copper baffles 2 and four connecting plates 3 together.
The hardness of the red copper partition plate 2 is lower than that of a carbon steel axle, so that the axle neck of the axle can be effectively prevented from being damaged; the red copper partition plates 2 with different thicknesses which can be suitable are selected according to the shaft necks with different sizes, so that the universality is enhanced; after the frock passes through certain life cycle, the red copper baffle 2 wearing and tearing are great back, only need to restore or the restoration that the frock can be accomplished to red copper baffle 2 of renewing after dismantling red copper baffle 2, has shortened the repair cycle greatly, has reduced manufacturing cost simultaneously.
When the universal axle dust guard mounting auxiliary tool is used, the red copper partition plate 2 is selected according to the size of an axle journal, and the tool is completely mounted; the dust guard is firstly sleeved on the shaft neck beside the axle dust guard seat, then the tool is sleeved at the end part of the axle shaft neck, two handles 5 are held by two hands, the dust guard is hammered forcibly until the dust guard is installed on the axle dust guard seat in an interference fit manner, and the installation of the dust guard is completed.
