Abstract
The utility model relates to a reverse cutter that draws of processing of automobile rear axle bearing frame hole, including reverse broach pole, set up at the connector of reverse broach pole tip, have the inserted hole on the connector, install the welding sword in the inserted hole, the afterbody of welding sword passes through bolt and connector fixed connection. The tool can process the inner hole, the end face and the chamfer of the bearing seat, the service cost of the replaceable welding tool is longer than that of a common inner hole tool, the machining size is stable, the replaceable welding tool can adjust the installation length and the installation angle according to the actual abdicating stroke of a workpiece, various workpiece machining is met, and the universality is high.
Description
Technical Field
The utility model belongs to the technical field of the machining technique and specifically relates to a reverse-drawing tool of automobile rear axle bearing frame hole processing.
Background
At present, the processing of automobile bearing seat hole, terminal surface and chamfer adopts ordinary reverse-pull lathe tool to process, and ordinary reverse-pull lathe tool generally need step down the stroke fixed, need customize specially to the great product of the stroke of stepping down, and the cost is higher, and the later stage uses blade processing cost also to be with high costs than using the welding sword.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defect that prior art exists, provide a reverse cutter that draws of processing of automobile rear axle bearing frame hole.
In order to realize the purpose, the utility model discloses a technical scheme as follows:
the utility model provides a reverse-pull cutter of automobile rear axle bearing frame hole processing, includes the reverse-pull cutter arbor, sets up the connector at the reverse-pull cutter arbor tip, has the inserted hole on the connector, installs the welding sword in the inserted hole, and the afterbody of welding sword passes through bolt and connector fixed connection.
Further, the connector and the reverse-pull cutter rod are integrally formed.
Further, the number of the bolts is more than two.
Further, the cutting edge of the welding knife faces outwards.
Further, the reverse-pull cutter rod is fixed in a cutter base of the machine tool.
The utility model has the advantages that: the tool can process the inner hole, the end face and the chamfer of the bearing seat, the service cost of the replaceable welding tool is longer than that of a common inner hole tool, the machining size is stable, the replaceable welding tool can adjust the installation length and the installation angle according to the actual abdicating stroke of a workpiece, various workpiece machining is met, and the universality is high.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in figure 1, the reverse-pulling cutter for machining the inner hole of the bearing seat of the rear axle of the automobile comprises a reverse-pulling cutter rod 1 and a connector 2 arranged at the end part of the reverse-pulling cutter rod 1, wherein an insertion hole is formed in the connector 2, a welding cutter 3 is installed in the insertion hole, and the tail part of the welding cutter 3 is fixedly connected with the connector 2 through a bolt 4.
Wherein, the connector 2 and the reverse draw knife bar 1 are integrally formed. The number of the bolts 4 is two or more. The cutting edge of the welding cutter 3 faces outwards, and the reverse-pull cutter rod 1 is fixed in a tool magazine of a machine tool.
This cutter can process bearing frame hole, terminal surface and chamfer, and interchangeable welding sword use cost is than ordinary inner hole cutter long service life, and the machining dimension is stable, and interchangeable welding sword 3 can be according to the work piece actual stroke adjustment installation length and installation angle of stepping down, satisfies various work piece processing, and the universality is strong.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
