Abstract
The invention relates to a two-point contact type flexible sliding universal joint and a processing process thereof. The invention solves the problems that the material is wasted and the processing is difficult in a processing process of a sliding universal joint. The two-point contact type flexible sliding universal joint provided by the invention comprises a sliding end case and a flange, the inner cavity of the sliding end case is a blind hole, the flange and the sliding end case are of a split type structure, and the flange is fixed at the bottom of the sliding end case. The processing process thereof comprises the following steps of: selecting steel and processing the steel into a vertical tube blank; carrying out finishing and forming in a blank mould to obtain the sliding end case by taking the bottom of the vertical tube blank as a reference; and welding the flange on the outer diameter at the bottom of the sliding end case. The flange and the sliding end case which are adopted are of the split structure, and the flange is welded at the bottom of the sliding end case, thus the processing difficulty of a product is greatly reduced; a bolt hole on the flange is directly punched and formed, thus being more convenient compared with the original drilling; and the working procedure is reduced, and no plug is used in the processing process provided by the invention, thus the material is saved and the cost is reduced.
Description
Technical field
The present invention relates to a kind of universal joint and processing technology thereof, be specifically related to a kind of 2 contacts around property slippage universal joint and processing technology thereof.
Background technology
Can axially movable tripod universal joint have plurality of advantages such as compact conformation, in light weight, low noise, reliability height, freedom from repairs.At present, the transmission system of the whole world car overwhelming majority all adopts the drive disk assembly of this universal joint as key.Because of the operating characteristic of its product, so concentricity and alley indexing accuracy between each alley of slippage end housing inner chamber are had relatively high expectations.Because of its structure uniqueness, so at present domestic and international manufacturing firm all adopts inner chamber precision forging technology.And domestic flange and shell are integral structure, because the slippage end housing process trouble because of complex structure when forging, and when operating more waste of material are arranged, and forge need process inner stopper again after finishing and adorn blanking cover, have increased manufacturing cost.
Summary of the invention
For overcoming problem in the background technology, the waste of material of avoiding the slippage universal joint in process, to cause, processing difficulties, it is simple to the invention provides a kind of processing, and 2 contacts of conservation are around property slippage universal joint and processing technology thereof.
The invention provides a kind of 2 contacts around property slippage universal joint, its technical scheme is: a kind of 2 contacts are around property slippage universal joint, comprise slippage end housing and flange, be provided with alley in the described slippage end housing, described flange is coaxial with the slippage end housing, the inner chamber of slippage end housing is a blind hole, and described flange and slippage end housing are split-type structural, and described flange is fixed on the bottom of slippage end housing.
As a kind of improvement of the present invention, the edge of the described slippage end housing bottom outer surface formation limited step that concaves, described flange is fixed on the limited step.
As another kind of improvement the of the present invention, fix by welding manner between flange and the slippage end housing.
As another kind of improvement the of the present invention, described flange is provided with positioning boss and positioning spigot.
The present invention provides the production technology of a kind of 2 contacts around property slippage universal joint simultaneously, and its technical scheme comprises the steps:
Choose steel, and process straight tubular blank;
Bottom with straight tubular blank is a benchmark, carries out the interior alley that finish forge goes out the slippage end housing in the base mould;
Welded flange on the bottom external diameter of slippage end housing.
As of a kind of improvement of 2 contacts around the processing technology of property slippage universal joint, before welded flange on the external diameter of the bottom of slippage end housing, process positioning spigot on flange, flange is and with slippage end housing bottom mutually welding spacing with the limited step on the slippage end housing by positioning spigot.
The invention has the beneficial effects as follows that the flange of employing and slippage end housing are split-type structural, flange is welded on the external diameter of slippage end housing bottom, lower the difficulty of processing of product greatly, in technical process of the present invention, also avoided the use blanking cover, save material, reduced cost.
Description of drawings
Accompanying drawing 1 is the structural representation of the embodiment of the invention.
Accompanying drawing 2 is the A-A cutaway view of Fig. 1 in the embodiment of the invention.
Among the figure, slippage end housing 1, three ball pin assembly 2, flange 3, bolt hole 31, positioning boss 4, positioning spigot 5.
The specific embodiment
Embodiments of the present invention is further illustrated below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with shown in Figure 2, a kind of 2 contacts are around property slippage universal joint and processing technology thereof, comprise slippage end housing 1, three ball pin assemblies 2 and flange 3, described slippage end housing 1 and flange 3 are split-type structural, described slippage end housing 1 inner chamber is evenly distributed on by three sections arc surfaces and forms three alleys in the endoporus, the outer wall of described slippage end housing 1 is three sections circular arc concave surfaces, described slippage end housing 1 inner chamber is a blind hole, described three ball pin assemblies 2 are located in the inner chamber of slippage end housing 1, the bottom outer surface edge of the described slippage end housing 1 formation limited step that concaves, flange 3 is provided with positioning boss 4 and positioning spigot 5, described positioning boss 4 and positioning spigot 5 are coaxial, and flange is spacing with the limited step on the slippage end housing 1 and weld mutually with slippage end housing 1 bottom by positioning spigot 5.Workpiece is processed according to the following steps: choose steel, and process straight tubular blank; Bottom with straight tubular blank is a benchmark, carries out profile and interior alley that finishing goes out the slippage end housing in the base mould; Process positioning spigot 5 on flange 3, flange 3 is spacing with the limited step on the slippage end housing 1 and weld mutually with slippage end housing 1 bottom by positioning spigot 5.The flange 3 and the slippage end housing 1 that adopt are split-type structural, make flange 3 be welded on slippage end housing 1 bottom again, lowered the difficulty of processing of product greatly, bolt hole 31 on the flange 3, positioning boss 4 and positioning spigot 5 direct drawings, more more convenient than original boring, both reduce operation, guaranteed respectively to locate the positional precision of benchmark again.In technical process of the present invention, slippage end housing bottom is a blind hole, need not refill and join blanking cover, has saved material, has reduced cost.
Every technical staff's notice: though the present invention describes according to the above-mentioned specific embodiment, invention thought of the present invention is not limited in this utility model, and the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
