Abstract
The utility model relates to the technical filed of diesel locomotives, in particular to a diesel locomotive draw gear machining clamp. The diesel locomotive draw gear machining clamp comprises a tool bottom plate, a pressing plate, a press fitting bolt and a supporting table. The press fitting bolt is connected with the tool bottom plate, the supporting table is located on the tool bottom plate, and the supporting table is composed of two primary locating tables, two secondary locating tables and two adjusting tables. The combined structure of the locating tables and the adjusting tables is adopted, in the process of operation, an operator firstly enables two locating reference planes on the front portion of a workpiece to be attached to reference planes of the primary locating tables, and then adjusts the two adjusting tables on the back portion manually until the top plane to be attached to two reference planes on the back portion of the workpiece. Therefore, excessive locating is avoided, clamping times are reduced, labor intensity and economic cost are reduced, great economic benefit is brought to enterprises, and quality guarantee is provided for meeting demands for high accuracy of hole positions.
Description
Technical field
The utility model relates to the diesel locomotive technical field, especially a kind of diesel locomotive hitch clamp for machining.
Background technology
Hitch is the connection that realizes between locomotive and railway carriage or railway carriage and the railway carriage, transmitting tractive power and impulsive force, and make between the vehicle diesel locomotive vitals that keeps certain distance, hitch material speciality on some locomotive (E level steel) hardness is big, product precision height, benchmark each other between each benchmark, and four small stair faces have requirement for height is at machine tool with not have good frock be to guarantee that the product that processes can satisfy drawing and require.What adopt at present is the positioning principle of plane and two pits, two small stair planes were datum plane in the past, utilize screw and briquetting workpiece pressing, carry out machined, but in practical operation, can occur milling out the step surface difference in height of coming at every turn and deviation can occur, and to mill out the difference in height of coming different at every turn, this gives that done tool locating datum level has brought trouble, both four step surfaces can not be simultaneously and the datum level of frock identical simultaneously, if brute force press-fits fitted simultaneously in four planes, can make workpiece be in positioning states, deviation appears in the positional precision that can cause like this processing, thereby makes the product that processes defective, influences result of use.
The utility model content
Low in order to overcome existing hitch processing unit (plant) precision, deviation is big, and efficient is low, influences the deficiency of hitch quality, and the utility model provides a kind of diesel locomotive hitch clamp for machining.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of diesel locomotive hitch clamp for machining, comprise frock base plate, pressing plate, press-fit bolt and brace table, press-fiting bolt is connected with the frock base plate, brace table is positioned on the base plate, and brace table is made up of two main positioning tables, two secondary positioning tables and two adjusting platforms.
According to another embodiment of the present utility model, comprise that further main positioning table is positioned at the front portion of frock base plate, secondary positioning table and adjusting platform are positioned at the rear portion of frock base plate.
According to another embodiment of the present utility model, comprise that further regulating platform is "T"-shaped double-screw bolt shape, is vertically connected on secondary positioning table top.
According to another embodiment of the present utility model, comprise that further regulating the platform top-side is provided with adjustment hole.
The beneficial effects of the utility model are, the structure that adopts positioning table and regulate the platform combination, during operation, earlier anterior two the location datum levels of workpiece and main locating table are fitted, platform is regulated at two at manual adjustments rear portion again, its top planes is sticked till latter two datum plane of workpiece, thereby avoided crossing the location.Utilize this anchor clamps, not only can be worked into the size in product front, can also be worked into the size of side, be to process a plurality of sizes under the same benchmark, satisfy technological datum requirement and product quality requirement, reduce clamping times, reduce labour intensity and financial cost, for enterprise brings bigger economic benefit, for high-precision hole site requires to provide quality assurance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is right view of the present utility model;
Fig. 3 is vertical view of the present utility model.
1. frock base plates among the figure, 2. pressing plate 3. press-fits bolt, 4. brace table, 5. main positioning table, 6. secondary positioning table, 7. adjusting platform, 8. adjustment hole.
The specific embodiment
Be structural representation of the present utility model as Fig. 1, Fig. 2 is right view of the present utility model, Fig. 3 is vertical view of the present utility model, a kind of diesel locomotive hitch clamp for machining, comprise frock base plate 1, pressing plate 2, press-fit bolt 3 and brace table 4, press-fit bolt 3 and be connected with frock base plate 1, brace table 4 is positioned on the base plate 1, and brace table 4 is made up of two main positioning tables 5, two secondary positioning tables 6 and two adjusting platforms 7.
According to another embodiment of the present utility model, comprise that further main positioning table 5 is positioned at the front portion of frock base plate 1, secondary positioning table 6 and adjusting platform 7 are positioned at the rear portion of frock base plate 1.Regulating platform 7 is "T"-shaped double-screw bolt shape, is vertically connected on secondary positioning table 6 tops.Regulate platform 7 top-side and be provided with adjustment hole 8.
The structure that adopts main positioning table 5, secondary positioning table 6 and regulate platform 7 combinations, during operation, earlier with two main positioning tables 5 and two secondary positioning table 6 applying frock faces, reverse side is fixed on the frock base plate 1 main positioning table 5 and secondary location 6 with bolt, squeeze into alignment pin at reverse side again, prevent that it from occurring rotating in process, make product processing error occur, main positioning table 5 is provided with two alignment pins, both plane and two pits positioning principle.Preceding two datum levels of workpiece and main positioning table 5 are fitted, platform 7 is regulated at two at manual adjustments rear portion again, utilize thin rod to insert adjustment hole 8, by rotation, regulate the height of platform 7, its top planes is sticked till latter two datum plane of workpiece, at last hitch is clamped, thereby avoided crossing the location.Utilize this anchor clamps, not only can be worked into the size in product front, can also be worked into the size of side, be to process a plurality of sizes under the same benchmark, satisfy technological datum requirement and product quality requirement, reduce clamping times, reduce labour intensity and financial cost, for enterprise brings bigger economic benefit, for high-precision hole site requires to provide quality assurance.
