The special clamp has the advantages that the structure is simple, the processing is convenient, in addition, the design is ingenious, safety and reliability are realized, the installation, the clamping and the positioning are fast, the processing precision of the rotating arm frames can be ensured, and the like.
Description
Technical field
The utility model relates to a kind of vertical lathe special fixture, particularly a kind of special fixture that adopts vertical lathe processing excavator pivoted arm frame main transmission hole.
Background technology
At present, the pivoted arm frame is the excavator key components and parts, the pivoted arm frame is divided into left-hand rotation jib and right-hand rotation jib, because its shape misconduct, be difficult to clamping, again in the process of its main transmission hole processing (this main transmission hole is and pivoted arm connecting rod assembly mating holes), because location difficulty, working (machining) efficiency is extremely low, and quality is difficult to again guarantee, be easy to produce waste product, economy to company has caused loss, at present with a left side, the right-hand rotation jib is placed on processes to guarantee machining accuracy on the Digit Control Machine Tool, but in a lot of small business, because the limited amount of Digit Control Machine Tool, in order to guarantee manufacturing schedule, still need to utilize common vertical lathe to process, process location difficulty at vertical lathe, difficult processing is to guarantee, so prior art is still perfect not.
Summary of the invention
Utility model purpose of the present utility model is: provide a kind of simple in structure, practical, clamping location quick, and can when adopting vertical lathe to process the driving hole of left and right pivoted arm frame, guarantee a kind of vertical lathe special fixture of its machining accuracy, to overcome the deficiencies in the prior art.
The utility model is achieved in that a kind of vertical lathe special fixture, comprise disc-shaped base, be provided with the positioning boss hole for locating element at the middle part of pedestal, be provided with the location backing pin of the left and right pivoted arm frame of two studs and convenient location at pedestal, be provided with pressing plate on the studs, the other end of pressing plate is arranged on the screw rod.
Be provided with the backing pin hole that to insert the location backing pin at pedestal.
Be provided with two at pedestal and can insert the backing pin hole that the location backing pin is located left and right pivoted arm frame.
Be provided with compression spring at studs.
Owing to adopted technique scheme, during the utility model work, at first with a left side, the circular positioning boss circle that the right-hand rotation jib has been processed is put into the positioning boss hole of pedestal, and so that the end face of the end face of part and pedestal fits positions, then with a left side, the right-hand rotation jib is close to backing pin, fasten part with pressing plate, just can be by common vertical lathe to a left side, the right-hand rotation jib carries out the processing of car owner's driving hole, the utility model compared with prior art, the utility model not only has simple in structure, advantage easy to process, and design ingenious, safe and reliable, the clamping location is quick, can guarantee left, right-hand rotation jib machining accuracy, the advantage such as increase work efficiency.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as to restriction of the present utility model.
Embodiment of the present utility model: the utility model is constructed according to following a kind of method in vertical lathe processing excavator pivoted arm frame main transmission hole that adopts, the method is to pass through first the mode of artificial line on the bottom face of the blank part of excavator pivoted arm frame, need the position in processing main transmission hole to draw a diameter greater than the basic circle of main transmission bore dia, then the blank part is clamped on the rotating disk of universal turing machine, and regulate according to basic circle, the center of circle of basic circle is adjusted on the center of turntable line of universal turing machine, then process a positioning boss circle at the blank part, then the blank part is taken off from vertical lathe, to be fixed on vertical lathe for the anchor clamps in processing excavator pivoted arm frame main transmission hole, because the pedestal at anchor clamps is provided with positioning boss hole and location backing pin, be inserted into the positioning boss circle on the blank part in the positioning boss hole of pedestal this moment, and the end face of the bottom face of part and pedestal fitted position, one side of part is abutted against on the backing pin of location, utilize pressing plate that part is fastened, guarantee that part can not move in process, utilize at last the vertical vehicle wheeled litter to go out the main transmission hole of pivoted arm frame, by such method, guarantee the machining accuracy in excavator pivoted arm frame main transmission hole, prevent from adding and man-hour occurs error.
The of the present utility model a kind of vertical lathe special fixture that makes up according to said method is, these anchor clamps comprise disc-shaped base 1, shown in Fig. 1～2, be provided with the positioning boss hole 2 for locating element at the middle part of pedestal 1, be provided with two studs 3 and convenient location backing pin 6 of locating left and right pivoted arm frame at pedestal 1, be provided with pressing plate 4 on the studs 3.
Be provided with the backing pin hole 7 that to insert location backing pin 6 at pedestal 1.
Be provided with two the backing pin holes 7 that can insert the left and right pivoted arm frame in location backing pin 6 location at pedestal 1.
Be provided with compression spring 5 at studs 3.
When processing left-hand rotation jib or right-hand rotation jib, will locate in the corresponding backing pin of the backing pin 6 insertions hole 7 and position.
During the utility model work, at first use the line processing method on the bottom face of blank part with vertical lathe, need the position in processing main transmission hole to draw a diameter greater than the basic circle of main transmission bore dia, then the blank part is clamped on the rotating disk of universal turing machine, and regulate according to basic circle, the center of circle of basic circle is adjusted on the center of turntable line of universal turing machine, then process a positioning boss circle 10 at the blank part, the positioning boss circle 10 that pivoted arm frame 9 has been processed is put into the positioning boss hole 2 of pedestal 1, and so that the end face of the bottom face of part and pedestal 1 fits positions, then pivoted arm frame 9 is close to location backing pin 6, fasten pivoted arm frame 7 with pressing plate 4 this moment, tighten the nut on the studs 3, after fixing part, guarantee that part can not move in process, utilize at last the vertical vehicle wheeled litter to go out the main transmission hole 11 of pivoted arm frame, by such method, guarantee the machining accuracy in excavator pivoted arm frame main transmission hole, prevent from adding and man-hour occurs error, after processing, unclamp the nut on the studs 3, utilize compression spring 5 that pressing plate 4 is upwards flicked, make things convenient for pivoted arm frame 9 to take out and get final product.
Utilize the main transmission hole 11 of the pivoted arm frame that this method processes with common vertical lathe, dimensional accuracy is high, has improved operating efficiency, is worthy to be popularized.
