Abstract

The utility model provides a shaft-disc type part end face rolling and extrusion tool with simple structure and easy processing, comprising a body, a rolling wheel having rolling end and shaft neck and an adjusting block, wherein one side of the body is provided with a clamping part, the rolling wheel is supported at the front end of the body by inner hole, support shaft and rolling shaft support arm, the head of the support shaft is lower than the end face of the rolling end; the adjusting is slidably matched with the other side of the body, the adjusting block is clamped on the body by a press part, two rolling bodies are arranged at the front end of the adjusting block by the connection shaft, two rolling bodies are symmetrically supported on the shaft neck of the rolling wheel; the rear end of the body is provided with an adjusting bolt, the head of the adjusting bolt contacts with the rear end of the adjusting block. When used, the rolling and extrusion tool is clamped on the lathe cutter carriage, the rolling end is utilized to roll and extrude the end face of workpiece so as to realize the rolling in place of grinding, thereby reducing investment and lowering processing cost of workpiece.

Description

Shaft-disc type component end face edging press tool

Technical field

The utility model relates to the machining tool of shaft-disc type component end face, the requirement of step surface low roughness, particularly at the edging press tool of processing low roughness (below the Ra0.8) end face, step surface in enormous quantities on the lathe.

Background technology

Outer thrust plate part on 10 tonnes of equalizing type of suspensions of Dongfeng Automobile is a shaft-disc type component, and step surface requires Ra0.8, produces in enormous quantities, can't guarantee the requirement of Ra0.8 on lathe with conventional turning; Though adopt grinding to guarantee, need to drop into face grinding machine, increase the parts fixation number of times, thereby increase product cost.

Summary of the invention

In order to reduce the processing cost of shaft-disc type component end face, the requirement of step surface low roughness, reduce investment, the utility model proposes the shaft-disc type component end face edging press tool that on lathe, uses.

The technical solution of the utility model: this edging press tool comprises body, has the rolling wheel of roll extrusion end and axle journal, adjusts piece, body one side is a clamping portion, at the body front end, the head of back shaft is lower than the end face of described roll extrusion end by its endoporus, back shaft, rolling bearing cantilever support for rolling wheel; Adjust piece and body opposite side and be slidingly matched, adjust piece and be clamped on the body by compressing member, its leading section is equipped with two rolling elements by connecting axle, and two rolling element symmetric support are on the axle journal of rolling wheel; The rear end of body is provided with the adjustment screw, adjusts the head and the back end in contact of adjusting piece of screw.

The beneficial effects of the utility model: described edging press tool is simple in structure, processing and manufacturing is easy.In use, be clamped on the lathe saddle by clamping portion, move and adjust piece, make the suitable precompression of generation between rolling element and the rolling wheel, and piece is adjusted in clamping, start lathe then, the roll extrusion end that moving carriage makes rolling wheel is pressed into appropriate depth being extruded the workpiece end face root, rolling wheel makes rolling wheel feed from inside to outside because friction is rotated with workpiece, finishes the edging of end face and presses, make the workpiece end face roughness reach Ra0.8-Ra0.4, thereby realize reducing investment, reduce the part end face processing cost to roll the generation mill.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 be among Fig. 1 along K to view.

The specific embodiment

Shaft-disc type component end face edging press tool as shown in Figure 1, 2, body 2 left sides are the A of clamping portion, rolling wheel 9 is made of roll extrusion end B and axle journal C, back shaft 4 passes the endoporus D of rolling wheel, two rolling bearings 7 in the body 2 front end installing holes, clamp rolling wheel by plain washer 5, spring washer 6, nut 3, make the rolling wheel cantilever support at body 2 front ends, wherein be provided with inner ring dottle pin 8 between two rolling bearings 7, the head of back shaft 4 is lower than the end face of roll extrusion end 9; Adjustment piece 14 passes on left guideway D with body and is slidingly matched, and the leading section of adjusting piece 14 is equipped with 15, two rolling bearing 15 symmetric support of two rolling bearings on the axle journal C of rolling wheel by connecting axle 11, and connecting axle 11 is fixing by jump ring 10; The rear end of body 2 is provided with adjusts screw 1, adjusts the head and the back end in contact of adjusting piece 14 of screw 1; Adjustment piece 14 passes the elongate slots E that is provided with on the adjustment piece by screw 13 and is clamped on the body 2,, the direction of extension of elongate slots E is consistent with the extension of guideway D, and is promptly consistent with the glide direction of adjusting piece 14; Be furnished with spring washer 12 on the elasticity screw 13 in addition, make clamping more reliable.

Obviously, above-mentioned rolling bearing 15 also can be replaced with needle bearing; Above-mentioned adjustment piece 14 also can be clamped on the body 2 by platen member, and just needn't be provided with elongate slots E this moment on the adjustment piece.The concrete structure combination is according to circumstances determined.

As follows in the course of work of using shaft-disc type component end face edging press tool on the lathe: (1), shaft-disc type component is clamped on the main shaft; (2) the edging press tool is clamped on the lathe saddle by the A of its clamping portion, unclamp screw 13, screw 1 is adjusted in turn moves adjustment piece 14, make the suitable precompression of generation between rolling bearing 15 and the rolling wheel, screw screw 13 and clamp adjustment piece 14, start lathe then, the roll extrusion end B that moving carriage makes rolling wheel is pressed into appropriate depth being extruded the workpiece end face root, rolling wheel makes rolling wheel feed from inside to outside because friction is rotated with workpiece, finishes the edging of end face and presses.

After the roll extrusion end wearing and tearing of rolling wheel, take off the conical surface, the chisel edge of rolling wheel reconditioning roll extrusion end, reusable rolling wheel, cost saving, the processing cost of reduction product.
