Description
Technical field
The utility model relates to a kind of clamping tool for machine work, is specifically related to a kind of for boring the drill jig of the outer circular hole of camshaft.
Background technology
Camshaft is important parts on logical machine, often need on cylindrical, process various holes, and these outer circular holes have angle requirement conventionally.The outer circular hole process equipment ubiquity complex structure of existing camshaft, fitting operation inconvenience, angle orientation benchmark is difficult to definite not high series of problems of machining accuracy that causes.
Utility model content
The purpose of this utility model is to provide a kind of special camshaft cylindrical drilling jig, has feature simple in structure, easy to install, machining accuracy is high.
For this reason, a kind of camshaft cylindrical drilling jig that the utility model provides, comprise base (1), and be installed in the column (2) on base (1), left support plate (3), right support plate (4) and camshaft are located flat side (6), described column (2) is between a left side, right support plate (3, 4) also forward setting between, key is: described column (2) upper end is installed with bushing plate (5), on bushing plate (5), be provided with the drill bit via hole (5a) of downward-extension on axis, the left side of described column (2) is installed with camshaft and locates flat side (6), described camshaft is located flat side (6) and is extended rearward to a left side, right support plate (3, 4) between, a described left side, right location-plate (3, 4) the rear position of leaning between is provided with camshaft pressing handle (7), described camshaft pressing handle (7) comprises compact heap (7a), slide block (7b) and return spring (7c), the lower end of described compact heap (7a) is hinged on base (1), the relative lower end, upper end of compact heap (7a) is towards top rake, the front end of the upper end of compact heap (7a) and slide block (7b) is fixed together, the rear end of slide block (7b) is connected with the upper end of return spring (7c), it is upper that the lower end of return spring (7c) is connected to base (1), and the front portion of described compact heap (7a) upper end is cut into vertical plane (A).
Be preferably, it is upper that described column (2) is fixed on base (1) by bolt (8), and described left support plate (3), right support plate (4), bushing plate (5) and camshaft are located flat side (6) and be fixed on column (2) by bolt (8).Be bolted, dismantle more convenient.
Using method, first press pressing handle, vacate behind enough spaces, again workpiece is put into drill jig, the left end of workpiece is shelved on left location-plate, and the right-hand member of workpiece is shelved on right location-plate, the rotational angle of camshaft is determined in the position of locating flat side by camshaft again, locate flat side when camshaft and just snap on camshaft after preposition, then unclamp pressing handle, by pressing handle, camshaft is compressed.
The beneficial effects of the utility model are: left and right location-plate plays the effect of auxiliary positioning to camshaft, camshaft is located the angle orientation of flat side to the outer circular hole of camshaft, in conjunction with pressing handle, camshaft is compressed simultaneously, realize the clamping of workpiece, positioning precision is high, correspondingly improves the machining accuracy of workpiece; When dismounting workpiece, only need to press pressing handle, very convenient quick; And simple in structure, low cost of manufacture; In addition, the front portion of compact heap upper end is whittled into vertical plane, to avoid the wedge angle damage camshaft of compact heap.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
