Abstract
The utility model provides automobile steering pump motor shaft step hole machining equipment which comprises a punching machine. A square plunger chip is arranged on a sliding block of the punching machine. A locking fixture is arranged below the square plunger chip. The clamping fixture comprises a base and a clamping piece. The clamping piece is located on the base. A motor shaft fixing hole is formed in the base and corresponds to the square plunger chip in position. When the motor shaft step hole machining equipment is used for machining a square hole in the lower half portion of a step hole, a prefabricated circular hole with the diameter slightly larger than the width of the square hole to be machined is machined at the bottom of the circular hole, then the square plunger chip is directly used for punching. Due to the fact that the diameter of the prefabricated circular hole is slightly larger than the width of the square hole, the square hole can be formed more easily in the extrusion deformation process of the plunger chip. By the adoption of the machining equipment, the square hole of the motor shaft step hole can be machined rather easily. Moreover, the machining equipment is quick in machining speed and high in machining efficiency.

Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide the steering pump of automobile motor shaft stepped hole that a kind of processing technology is simple, process velocity is fast, production efficiency is high process equipment.
For achieving the above object and other relevant objects, the utility model provides a kind of steering pump of automobile motor shaft stepped hole process equipment, it comprises a stamping machine, the slide block of described stamping machine is provided with a square drift, the below of described square drift is provided with a locking fixture, and described locking fixture comprises a base and clamping element, and described clamping element is positioned on described base, described base is provided with a motor shaft fixing hole, and described motor shaft fixing hole is corresponding with described square drift position.
Preferably, four angles of described square drift lower surface are fillet.
Preferably, in described motor shaft fixing hole, be provided with buffer spring.
As mentioned above, steering pump of automobile motor shaft stepped hole process equipment of the present utility model has following beneficial effect: adopt this steering pump of automobile motor shaft stepped hole process equipment adding man-hour to the square opening of stepped hole the latter half, first at the bottom of circular port processing diameter, should be slightly larger than the prefabricated circular port that will process square opening width, then directly adopt square drift to carry out punching press, because the slightly larger in diameter of prefabricated circular port is in the width of square opening, therefore in drift compressional deformation process, can comparatively be easy to formation direction hole.Adopt this process equipment to be comparatively easy to the square opening of motor shaft stepped hole to process, its process velocity is fast, and working (machining) efficiency is high, under the prerequisite that guarantees crudy, can effectively enhance productivity.

The specific embodiment
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this description.
Refer to Fig. 1.Notice, appended graphic the illustrated structure of this description, ratio, size etc., equal contents in order to coordinate description to disclose only, for person skilled in the art scholar, understand and read, not in order to limit the enforceable qualifications of the utility model, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this description, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under without essence change technology contents, when being also considered as the enforceable category of the utility model.
As shown in Figure 1, the utility model provides a kind of steering pump of automobile motor shaft stepped hole process equipment, this process equipment comprises a stamping machine 1, and the slide block 2 of stamping machine 1 is provided with a square drift 3, can drive square drift 3 to move up and down carry out punching press by slide block 2 stamping machines 1.Below square drift 3, be provided with a locking fixture, this locking fixture comprises a base 4 and clamping element 7 two parts, clamping element 7 is positioned on base 4, base 4 is provided with a motor shaft fixing hole 5, motor shaft fixing hole 5 is corresponding with the position of square drift 3, and the size dimension of square drift 3 should be consistent with the size that will process square opening.Motor shaft fixing hole 5 is for placing the motor shaft of wanting punching press, and clamping element 7, for clamping motor axle, is fixed on locking fixture motor shaft.The structure of clamping element 7 is prior art, therefore be not described in detail at this.
This equipment is for processing the stepped hole of motor shaft, and as shown in Figure 1, the stepped hole of motor shaft 8 comprises the circular port 81 of the first half and the square opening 82 of the latter half, and the diameter of circular port 81 is greater than the width of square opening 82.Stepped hole to this motor shaft adds man-hour, first motor shaft is fixed, and uses drill bit at the circular port 81 on the end face processing step hole top of motor shaft.And then use drill bit in the bottom of circular port 81, to process a prefabricated circular port, and the diameter of this prefabricated circular port should be slightly larger than the width that will process square opening 82, and the working depth of prefabricated circular port is greater than the degree of depth that will process square opening 82.Then make motor shaft stepped hole direction upwards motor shaft 8 is fixed on locking fixture, then start stamping machine 1 and drive square drift 3 prefabricated circular port to be carried out to punching press downwards.For the ease of square drift 3, enter in prefabricated circular port, four angles of the lower surface of square drift 3 should be set to fillet.In order to prevent motor shaft distortion, can be at the interior buffer spring 6 that arranges of motor shaft fixing hole 5, because the other end of motor shaft is provided with ring-shaped step (as shown in Figure 1), this buffer spring 6 can just in time be stuck on ring-shaped step, can play certain cushioning effect to motor shaft 8 like this in punching course.
