Abstract
The invention provides a lathe device for axially fixing a bearing. The lathe device comprises a lathe and a rolling tool, wherein the rolling tool comprises a tail handle, a connection plate and a plurality of rolling assemblies, wherein the rolling assemblies are arranged on the front end face of the connection plate, are distributed circumferentially, and comprise pressing pins, pressing sleeves and balls; the pressing pins are fixedly connected to the front end face of the connection plate, and are sleeved with the pressing sleeves; the balls are embedded into the front parts of the pressing sleeves, and are pressed against the front ends of the pressing pins; and the connection plate is fixedly and coaxially connected with the tail handle which is positioned behind the connection plate. The fixing reliability can be enhanced effectively, a simple process is adopted, and high production efficiency is realized. The rolling tool is simple in structure, is low in cost, is easy to manufacture, works stably in cooperation with an ordinary lathe, and has a low fault rate; a bearing inner ring swings or rotates flexibility after rolling and closing, and has high consistence.
Description
Technical field
The present invention relates to a kind of process equipment based on engine lathe, be mainly used in bearing (such as ball bearing, roller bearing, oscillating bearing etc.) is fixed in the metal shell, prevent the bearing axially-movable.
Background technology
Fixing of deep groove ball bearing, roller bearing and oscillating bearing in steel and the non-ferrous metal housing, its conventional method is with in the axle pressure hatch, rushes a little at bearing outer ring and metal shell junction.Adopt the method, reliability is low and unstable.
Summary of the invention
For solving between prior art bearing and steel and the non-ferrous metal housing the fixedly low and unsettled problem of reliability, the invention provides a kind of lathe apparatus for the bearing axial restraint, but the reliability that Effective Raise is fixing, and technique is simple, has higher production efficiency.
Basic solution of the present invention is as follows.
A kind of lathe apparatus for the bearing axial restraint, comprise lathe and roll extrusion frock, described roll extrusion frock comprises caudal peduncle, connecting plate and is installed on a plurality of roll extrusion assemblies that the connecting plate front end face is circle distribution, described roll extrusion assembly comprises pad, gland and ball, pad fixedly is crimped on the connecting plate front end face and is socketed with gland, and described ball is embedded in the interior front portion of gland and offsets with the pad front end; Connecting plate and coaxial being fixedly connected with of described caudal peduncle that is positioned at its rear;
Bearing to be fixed is preset in the metal shell, and this metal shell is coaxial fixing with lathe spindle on lathe by the lathe three-claw clamping chuck; The caudal peduncle of roll extrusion frock fixedly is clamped on the tailstock of lathe, and described a plurality of roll extrusion assemblies are over against the rolling beading position of bearing to be fixed.
Based on above-mentioned basic technical scheme, can also further do following optimization and limit and improve:
The center of above-mentioned connecting plate is fixedly installed alignment pin.Can locate better metal shell to be processed and bearing like this.
Front portion in the above-mentioned gland is coated with lubricating grease.Like this, ball is in gland, and lubricating grease not only can play lubricated effect, utilizes simultaneously its viscosity can also prevent that ball from dropping.
Above-mentioned roll extrusion assembly has 4, is distributed on the same circumference.
Above-mentioned connecting plate is to be fixedly connected with caudal peduncle with two soket head cap screws by two straight pins, and two straight pin place straight lines are mutually vertical with two hex screw place straight lines.
The present invention has the following advantages:
The present invention utilizes engine lathe, has realized reliable and stablely fixedly ball bearing, roller bearing and oscillating bearing.
Among the present invention, the roll extrusion tool structure is simple, and cost is lower, is easy to make, and stablizes cooperating with engine lathe, failure rate is low; Bearing inner race behind the rolling beading swings or rotation is flexible and uniformity is better.
Description of drawings
Fig. 1 is the schematic diagram that roll extrusion frock that the present invention designs cooperates with the roll extrusion for the treatment of rigid bearing.
Fig. 2 is the left view of Fig. 1.
The drawing reference numeral explanation:
The bearing that 1-is to be fixed; The 2-metal shell; The 3-alignment pin; The 4-ball; The 5-gland; The 6-pad; The 7-connecting plate; The 8-straight pin; The 9-socket cap screw; The 10-caudal peduncle.
The specific embodiment
As shown in Figure 1, the roll extrusion frock of the present invention's design mainly is made of caudal peduncle 10, connecting plate 7, pad 6, gland 5, alignment pin 3 and ball 4 etc.Four pads 6 are pressed into respectively in the hole that connecting plate 7 front end faces preset, and gland is pressed in respectively on the corresponding pad, is undertaken spacing by connecting plate.Socket cap screw 9 and straight pin 8 that employing is positioned at the pad periphery link together connecting plate 7 and caudal peduncle 10.Add lubricating grease in the gland, ball 4 is put among the gland.The lubricating grease of putting into not only can play lubricated effect, utilizes simultaneously its viscosity can also prevent that ball from dropping.
Bearing to be fixed is preset in the metal shell according to common way, and this metal shell is coaxial fixing with lathe spindle on lathe by the lathe three-claw clamping chuck; The caudal peduncle of roll extrusion frock fixedly is clamped on the tailstock of lathe, and a plurality of roll extrusion assemblies of roll extrusion frock are over against the rolling beading position of bearing to be fixed.
Bearing rolling beading process: tail stock is moved along major axes orientation, bearing rolling beading device (ball 4) is contacted (outer fix of bearing place circumference) with steel or non-ferrous metal housing, utilize simultaneously the dial gauge zeroing to determine to receive the benchmark of pressing the degree of depth.The lathe spindle rotation drives steel or non-ferrous metal housing and rotates, and tail stock, makes its surface that the plastic deformation of local trace occur, thereby reaches the rolling beading requirement of bearing by a certain amount of feeding along major axes orientation.
