Abstract
The invention discloses a drilling clamp, and particularly relates to a clamp for drilling two holes of a diesel engine rocker arm shaft seat. The drilling clamp comprises a clamp body, a positioning plate of a positioning mechanism, a positioning rod with a clamping thread and a locking thread, a drilling template, drilling sleeves, an opening press plate and a knurled clamping nut. The drilling clamp is characterized in that the clamp body is formed by perpendicularly connecting a clamp baseplate and a supporting plate, one end of the positioning rod with a clamping stud is fixed in the supporting plate, a positioning platform for end face positioning, an edge cutting pin used for hole positioning and a stud nut for tightening the opening press plate are arranged at the other end of the positioning rod, the drilling template is mounted above the supporting plate, drilling plate holes identical with workpiece holes in number are formed above a drilling plate, and each drilling sleeve is arranged in the corresponding drill plate hole and used for guide drilling of a drill bit. The drilling clamp has the advantages of simple structure, accuracy in positioning, reliability in clamping, high adaptability and the like.
Description
Technical field
The present invention relates to a kind of processing technology equipment, particularly one rocker shaft bed bores diplopore fixture.
Background technology
Rocker shaft bed is one of diesel engine intake and exhaust structure member, its effect is mainly used in installing rocker arm shaft; rocker arm shaft Main Function supports rocking arm exactly; and the Main Function of rocking arm is the size regulating valve to open; thus the size that can conveniently regulate valve to open makes the speed of air inlet and exhaust adjusted; and rocker shaft bed role in diesel engine air distribution system is extremely important; in actual production; ensure crudy, and the adopted way that boosts productivity is that the special technological equipment of design carries out production and processing.
Summary of the invention
The present invention designs a kind of boring grab, by clamp body (1), nut (2), location-plate (10), with locking screw (4-1) and the backstay (4) clamping screw thread (4-6), bushing plate (6), drill bushing (7), opening pressing plate (8), the compositions such as binding nut (9), it installs two location-plates (10) primarily of clamp body (1) base plate (1-1), positioning workpieces bottom surface, positioning boss (4-3) end face positioning workpieces side on backstay (4), backstay chamfered edge pin (4-4) positioning workpieces hole, binding nut (9) screws in the clamping screw thread (4-6) of backstay (4), compress or unclamp opening pressing plate (8), can clamp or unclamp workpiece.
One of technical solution problem of the present invention, designed boring grab has rational setting element to eliminate freedom of workpiece, to realize the accurate location of workpiece.
Another technical problem that the present invention solves, designed boring grab has rational tool setting device, namely bushing plate, should have with workpiece hole quantity and apart from identical drill jig hole.
The technical problem again that the present invention solves, designed boring grab has the clamp system of convenient and swift economy.
Feature of the present invention: accurate positioning, is convenient to tool setting, clamps convenient and reliable, is beneficial to and enhances productivity.

Fig. 1 is the structural front view of boring grab, Fig. 2 is clamp body (1) front view, the structural representation of Fig. 3 opening pressing plate (8), Fig. 4 is the structural representation of backstay (4), and Fig. 5 is the sectional drawing of the chamfered edge pin (4--4) of backstay (4).
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the invention scheme is described, accompanying drawing is further illustrating the technology of the present invention content, not limitation of the present invention.
See accompanying drawing 1, the present invention designs a kind of boring grab, particularly rocker shaft bed bores diplopore fixture, sandwiches concrete (1), nut (2), location-plate (10), the composition such as backstay (4), bushing plate (6), drill bushing (7), opening pressing plate (8), binding nut (9) with locking screw (4-1) and clamping screw thread (4-6).
The present invention its primarily of clamp body (1) base plate (1-1), two location-plates (10) are installed, rocker shaft bed bottom surface, location, cut the three degree of freedom (degree of excursion eliminating rocker shaft bed, two swings) positioning boss (4-3) end face positioning workpieces side on backstay (4), backstay chamfered edge pin (4-4) positioning workpieces hole, binding nut (9) screws in the clamping screw thread (4-6) of backstay (4), compress or unclamp opening pressing plate (8), can clamp or unclamp workpiece.
Fig. 1, reading room, in Fig. 4, support plate (1-2) inner hole of backstay (4) cylindrical (4-2) and clamp body (1), nut (2) locking positioning bar (4) makes it be fixed on clamp body (1), the side of backstay (4) positioning boss (4-3) end face location rocker shaft bed, eliminate rocker shaft bed two frees degree (degree of excursion and a swing), backstay (4) chamfered edge pin (4-4) eliminates workpiece degree of excursion, realizes rocker shaft bed and locates completely.
Fig. 1, in Fig. 5, backstay (4) clamping screw thread (4-6) screws in nut (9); rocker shaft bed endoporus is greater than nut (9); can drill-through backstay (4); with base plate (10); positioning boss (4-3) end face; the flat position of chamfered edge pin (4-4) realizes the location completely of shaking thumb axle bed; as shown in Figure 1; pressing plate (8) directly snaps between rocker shaft bed and binding nut (9), screws in and screws out binding nut (9), can realize the clamping of rocker shaft bed and unclamp.
Above-described embodiment is only for the present invention's; and be not limitation of the present invention; under the premise without departing from the spirit and scope of the present invention, the various equivalent structure changes made are all within protection scope of the present invention, and protection scope of the present invention is defined by the claims for those skilled in the art.
