Description
Technical field
The utility model relates to a kind of rolling tools, especially cylinder bore rolling tools that the hole carried out rolling and processing.
Background technology
The hole processing of general hydraulic cylinder series, because the serviceability requirement of part, precision prescribed height not only, and require hole surface to have certain wearability, and the rolling technology means can make hole surface produce hardened layer, and rolling step is except that can guaranteeing that dimensional accuracy and surface roughness require, also can strengthen finished surface, strengthen the surface texture tight ness rating, improve the hardness and the wearability of metal surface, thereby improved the serviceability of cylinder body.
The rolling and processing method in hole is to utilize that diameter is bigger slightly than aperture to be processed, the higher rolling tools of hardness pass through preprocessing hole by force, make the metal of hole wall surface layer produce plastic deformation, thereby meet the requirements of dimensional accuracy and surface roughness, rolling and processing can also play and proofread and correct hole shape, change effects such as aperture size, strengthening surface except that having working (machining) efficiency height, machining accuracy and surface quality height, process stabilizing, characteristics such as easy and simple to handle.
The structural design of the milled head that roller, roller rolling retainer and roller axial direction positioning device are formed in the rolling tools is very important, is directly connected to the manufacturing complexity of milled head and stablizing of performance.The structure of existing rolling tools such as Fig. 1～shown in Figure 3, among the figure, 1, the M14 screw, 2, roller, 3, tapered sleeve, 5, support set, 6, dial, 7, thrust bearing, 8, back of the body cap, 9, mandrel, 11, bearing pin, 12, pin, 14, the M4 sunk screw, 15, roller rolling retainer, 16, packing ring, 19, key, 20, stop collar, 21, cover, 22, threaded, 23, pillar.Wherein, milled head comprises the pillar 23 of roller 2, roller rolling retainer 15 and supporting roller axial location, on the cross section of roller rolling retainer, the roller locating hole is horn mouth shape (seeing shown in Figure 3), promptly be two-way angle, can't process, can only process with file by the workman with machinery, angle and size are difficult to guarantee that difficulty of processing is bigger; Pillar 23 1 ends are cylinder, and the other end is spherical, and roller must be consistent at axial location, just require pillar length dimension precision very high, the sphere end difficulty of processing of pillar is very big, is difficult to guarantee the unanimity of roller on axial location, in addition, the pillar of this structure rotates also underaction.The roller of the milled head design in traditional cylinder bore rolling tools is less, causes rolling quantity little, and roll extrusion efficient is low.
The utility model content
The technical problems to be solved in the utility model provides the cylinder bore rolling tools that a kind of roller rolling retainer is easy to process.
The technical solution of the utility model is: a kind of cylinder bore rolling tools, comprise milled head, milled head comprises roller rolling retainer and support set, roller rolling retainer is the end tooth structure towards an end of support set, between the roller rolling retainer adjacent teeth, roller is housed, has the roller axial direction positioning device between roller end face and the support set, relative two parallel sided of roller rolling retainer adjacent teeth are in the symmetrical centre plane of these two sides, this symmetrical centre plane is provided with radially anti-drop device of roller by the center of roller rolling retainer on the outer surface of roller rolling retainer tooth.
Described roller axial direction positioning device is one to be inlaid in the ball between roller and the support set.
Also be provided with ball retainer between roller and support set, described ball is loaded on ball and holds in the ball locating hole in the frame, and the diameter of ball is greater than the thickness of ball retainer.
Described roller radially anti-drop device is the elastic pressuring plate that is fixedly arranged on each tooth outer surface of roller rolling retainer, the corresponding pressure on two adjacent rollers that touch in these tooth both sides, elastic pressuring plate place of pressure contravention that each elastic pressuring plate stretches out to both sides, the pressure contravention of described elastic pressuring plate has at least one to press fingertip.
The position that the outer surface of described roller rolling retainer tooth is installed elastic pressuring plate is a plane.
The utility model is changed into the axial sides that the location of roller is installed on the roller rolling retainer parallel surface of unidirectional angle by the horn mouth of two-way angle, roller is pushed down by the elastic pressuring plate that is fixed on the roller rolling retainer, make the roller locating hole be suitable for adopting machining, machining accuracy and efficient all are improved.The axial location of each roller is limited by ball, because ball can directly be selected satisfactory high accuracy standard ball for use, replaced unmanageable pillar in the former rolling tools, can carry out axial location to roller like this, raw material and man-hour have been saved again, also make simultaneously the roller location more accurate, rotate more flexible.In addition, the utility model can be selected larger-diameter roller for use after the roller locating hole is improved, and makes rolling quantity bigger, and working (machining) efficiency is higher.
The utility model only improves the milled head of original rolling tools, has not only reduced the manufacture difficulty of milled head, and has improved the performance of cylinder bore rolling tools greatly.
