Abstract
The invention discloses a self-positioning thread rolling burring machine used on a brake bottom plate and a brake shoe of a brake. The machine comprises a body and end portions, the body is located in the middle, the end portions are located on the two sides of the body, the body and the end portions are coaxial, the outer diameter of the body is larger than the outer diameter of the end portions, and the body is inserted into a self-positioning thread rolling burring machine hole of the brake bottom plate and is in interference fit with the self-positioning thread rolling burring machine hole. The self-positioning thread rolling burring machine is in interference fit with the hole in the brake bottom plate, so that existing bushes are omitted, and the number of parts is reduced. Besides, the end portions are lengthened, so that the supporting area and the length of the brake shoe are increased, and the brake shoe is more stable and not prone to swinging.
Description
Technical field
The present invention relates to auto parts and components processing technique field, more particularly, relate to the self-align flat die thread rolling burring machine using on a kind of axle head.
Background technology
Trailer semitrailer axle belongs to driven shaft, axle head need to be on external screw thread keyseat and draw-bore, at keyway and pin-and-hole place, produce burr, if that burr removing is unclean, during axletree assembling, gently affect threaded engagement, heavy scrap whole piece axletree.The method of removing at present screw thread keyway place burr is the instrument deburrings such as coil file cutter for manpower, and manpower deburring quality is unstable first, and labour intensity is large; Second productive temp is slow, and the flash removed that completes one end spindle nose takes 25 seconds, and can not realize spindle nose two ends flash removed simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of energy quick, effective by the clean self-align flat die thread rolling burring machine of the burr removing on axle head, to overcome the deficiencies in the prior art.
The technical solution adopted for the present invention to solve the technical problems is: a kind of self-align flat die thread rolling burring machine, comprise support, axletree is placed on the pillow block of support, self-align stranding burr mechanism is set near spindle nose, described self-align stranding burr mechanism comprises two power cylinders and threading die seat, the output shaft of the first power cylinder connects briquetting, described briquetting by the second power cylinder to pressing down; The cylinder ends of described the second power cylinder is hinged on support, the output shaft of described the second power cylinder connects threading die seat, the operative end surface of described threading die seat is provided with flat die thread rolling, the flat die thread rolling of described threading die seat and spindle nose screw thread are suitable, the flat die thread rolling of described threading die seat is fitted on spindle nose screw thread, and described the second power cylinder drives threading die seat along the rubbing back and forth of spindle nose screw thread.
The operative end surface of described threading die seat is cambered surface and suitable with spindle nose screw thread cylindrical.
Described the first power cylinder is cylinder.
Described the second power cylinder is cylinder.
Described briquetting comprises the pressing working face of arc, and the outer wall of cylinder block of described pressing working face and the second power cylinder is suitable, and described briquetting is pressed on the cylinder body of the second power cylinder.
Compared with prior art, the invention has the beneficial effects as follows:
1) self-align flat die thread rolling burring machine of the present invention has self-locating function, does not destroy the original precision of screw thread.
2) self-align flat die thread rolling burring machine of the present invention only need be changed the removing that a part can be realized all size screw thread keyway place burr, practical, easy and simple to handle, is worthy of popularization.
3) self-align flat die thread rolling burring machine production efficiency of the present invention is high, and single-ended or two ends only process all simultaneously and need 15 seconds, than current productive temp fast 67%.

The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Referring to Fig. 1-6, self-align flat die thread rolling burring machine of the present invention, comprises support 1, and axletree 3 is placed on a pair of shaft supporting frame 2 of support pillow block, and self-align stranding burr mechanism is set near spindle nose.See Fig. 3-4, axle head need to mill out keyway 11 on external screw thread, after milling, at screw thread edge 12 places of keyway, can produce burr, and self-align flat die thread rolling burr function of the present invention is removed the burr at screw thread edge 12 places, specific as follows:
Self-align stranding burr mechanism comprises two power cylinders and threading die seat, and two power cylinders are all cylinders.The first power cylinder 4 is vertically rack-mount, its output shaft connects briquetting 5, and briquetting comprises the pressing working face of arc, and the outer wall of cylinder block of described pressing working face and the second power cylinder is suitable, briquetting is pressed on the cylinder body of the second power cylinder, by the second power cylinder 6 to pressing down.The cylinder ends 9 of the second power cylinder 6 is hinged on support 1, and the output shaft 7 of the second power cylinder connects threading die seat 8, and the operative end surface of threading die seat is provided with flat die thread rolling, and the flat die thread rolling of threading die seat and spindle nose screw thread are suitable.The operative end surface of threading die seat is cambered surface and suitable with spindle nose screw thread cylindrical.During work, the flat die thread rolling of threading die seat is fitted on spindle nose screw thread, by the second power cylinder 6, drives threading die seat 8 along the rubbing back and forth of spindle nose screw thread.Because briquetting is pressed on the cylinder body of the second power cylinder, therefore, threading die seat 8 is fitted on spindle nose screw thread all the time, and the cylinder ends 9 of the second power cylinder 6 is hinged on support 1, make cylinder body or swing up and down certain limit around about pin joint, thereby make the flat die thread rolling of threading die seat 8 can rubbing back and forth on fixed spindle nose screw thread.See Fig. 5-6, the duty of flat die thread rolling can be decomposed into along spindle nose axial direction move axially A and, along the B that moves radially of spindle nose circumferential direction.
More than open is only specific embodiments of the invention; do not form limiting the scope of the invention; for general technical staff of the technical field of the invention; do not departing under general idea prerequisite of the present invention; variation and the replacement without process creative work according to technical solution of the present invention, done, within all should dropping on protection scope of the present invention.
