Abstract
The invention discloses a transmission shaft pressure square, which comprises a pressure block, a locating block for locating a transmission shaft and an ejector rod matched with the pressure block. A formed hole passing through two ends of the pressure block is arranged on the pressure block. The ejector rod is inserted in the formed hole. In the event of manufacturing the transmission shaft, the transmission shaft is only necessary to be extruded in the formed hole; therefore, the transmission shaft can be symmetrical.
Description
Technical field
The present invention relates to the method for a kind of transmission axial compression side and manufacturing power transmission shaft, particularly a kind of have the transmission axial compression side that improves structure and utilize this improved transmission axial compression side to make the method for power transmission shaft.
Background technology
See also Fig. 1 and shown in Figure 2; Be a kind of existing transmission axial compression side 100 '; This transmission axial compression side 100 ' has two cross sections and is the first pressure side 11 ' and the second pressure side 12 ' semicircle and that can cooperatively interact; And this first pressure side 11 ' and the second pressure side 12 ' all have the groove that is oppositely arranged, and the shape after this two groove fit is the shape (type of being generally is square) that power transmission shaft need be processed.One end of the said power transmission shaft 200 ' shape that formation needs under this two pressure side 11 ', 12 ' extruding.
But, when adopting above-mentioned transmission axial compression side 100 ' to make power transmission shaft, being difficult to pass through accurately the center of circle because first side of pressureing 11 ' and the second pressure side 12 ' are stressed when pushing mutually, the power transmission shaft that causes being pressed into is asymmetric.
Therefore, need a kind of new technical scheme to address the above problem.
Summary of the invention
To the problem and shortage that prior art exists, the purpose of this invention is to provide a kind of method that can process the transmission axial compression side of symmetrical power transmission shaft and make power transmission shaft.
For realizing above-mentioned purpose, transmission axial compression of the present invention can be adopted following technical scheme:
A kind of transmission axial compression side comprises briquetting, reaches the push rod that cooperates with briquetting in order to the locating piece of locating power transmission shaft, and said briquetting is provided with the moulding hole of running through these briquetting two ends, and said push rod is inserted in the moulding hole.
The present invention is compared with prior art: briquetting is provided with the moulding hole of running through these briquetting two ends, thus only need power transmission shaft is squeezed in the moulding hole promptly plastic, so can make power transmission shaft symmetrical.
For realizing above-mentioned purpose, the method that the present invention makes power transmission shaft can adopt following technical scheme:
Make the method for power transmission shaft, comprise the steps,
(1), an end of power transmission shaft is positioned on the locating piece, and an other end is positioned over porch, moulding hole;
(2), locating piece is moved to briquetting, an end that makes power transmission shaft be arranged in porch, moulding hole is pressed into moulding hole and moulding;
(3), will be inserted in push rod in the moulding hole relies on the power transmission shaft in the moulding hole and with power transmission shaft and ejects the moulding hole.
The present invention is compared with prior art: through power transmission shaft being pressed in the moulding hole and moulding, can make the power transmission shaft symmetry.After moulding is accomplished, utilize push rod that power transmission shaft is ejected the moulding hole, be convenient to power transmission shaft and in the moulding hole, take out.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment; Further illustrate the present invention; Should understand the following specific embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
See also Fig. 3 to shown in Figure 6, the invention provides the method for a kind of transmission axial compression side and manufacturing power transmission shaft.
Said transmission axial compression side comprises briquetting 11, reaches the push rod 13 that cooperates with briquetting 11 in order to the locating piece 12 of locating power transmission shaft 200.Said briquetting 11 is an integral type, and is provided with the moulding hole 111 (in this embodiment, section type of being in said moulding hole 111 is square) of running through these briquetting 11 two ends, and said push rod 13 is inserted in the moulding hole 111.The porch in said moulding hole 111 is provided with the guiding face 112 of inclination in order to guide power transmission shaft to dock with the inlet in moulding hole 111 easily.Locating piece 12 is provided with the locating slot 121 in order to location power transmission shaft 200.
Please continue to consult Fig. 3 to shown in Figure 6, use the method for above-mentioned transmission axial compression side manufacturing power transmission shaft 200 to comprise the steps,
(1), an end 21 of power transmission shaft 200 is positioned on the locating piece 12, and an other end 22 is positioned over 111 porch, moulding hole;
(2), locating piece 12 is moved to briquetting 11, an end 22 that makes power transmission shaft 200 be arranged in 111 porch, moulding hole is pressed into moulding hole 111 and moulding;
(3), will be inserted in push rod 13 in the moulding hole 111 relies on the power transmission shaft 200 in the moulding hole 111 and with power transmission shaft 200 and ejects moulding hole 111.
The present invention compared with prior art through power transmission shaft 200 being pressed in the moulding hole 111 and moulding, promptly can make power transmission shaft 200 symmetries under the situation of moulding hole 111 symmetries.After moulding is accomplished, utilize push rod 13 that power transmission shaft 200 is ejected moulding hole 111, be convenient to power transmission shaft 200 and in moulding hole 111, take out.
