Abstract
The invention discloses an upper surface positioning drill jig to solve the technical problems. The upper surface positioning drill jig consists of a jig body, a lower movable center, a center stand, a clamping cam and a handle, wherein the jig body has a [ shape, an upper beam of the jig body is provided with a vertical drill hole, and the lower surface of the upper beam is provided with a positioning reference plane; the lower beam of the jig body is provided with the handle and the clamping cam; the upper part of the clamping cam is provided with the center stand and the lower movable center; and the upper positioning surface of a workpiece is put into the positioning reference plane of the jig body, the handle below is pulled to rotate the clamping cam 5, and the center stand and the lower movable center are pushed to move upwards so as to clamp the workpiece for drilling. Because the upper surface of the workpiece is positioned by the upper surface positioning drill jig, the machining reference and the measurement reference are completely overlapped, and the workpiece machining precision can meet the requirement of a process.
Description
Technical field
The present invention relates to the machining anchor clamps, be specifically related to a kind of upper surface location drilling anchor clamps.
Background technology
At M6 engine balance device trunnion shaft end face dowel hole is arranged, the pin-and-hole depth tolerances is 6 ± 0.05mm, be with trunnion shaft lower surface location drilling, because the influence of trunnion shaft length overall tolerance can't guarantee that the pin-and-hole size is qualified.Therefore, locate mode when changing Workpiece boring with trunnion shaft upper surface location, clamps, holes from the upper end workpiece from lower axial end, guarantee the depth tolerances of pin-and-hole, and the difficult anchor clamps of existing lower surface location drilling are to reach the requirement of upper surface location drilling.
Summary of the invention
The present invention discloses a kind of upper surface location drilling anchor clamps, to solve the problems of the technologies described above.Upper surface location drilling anchor clamps of the present invention are made up of clamp body, following rolling center, top bearing, clamping cam and handle; Clamp body be [shape, its entablature lower surface is provided with the location datum level; Sill assembling handle and clamping cam clamp top bearing of cam upper unit and following rolling center.
Described clamp body entablature has vertical drill bit bore.
The present invention is helpful to be: with the workpiece surface location drilling, accurate to dimension reaches process stipulation.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is a upper surface boring grab schematic diagram.
Among the figure: clamp body 1, workpiece 2, following rolling center 3, top bearing 4, clamping cam 5, handle 6, location datum level 7.
The specific embodiment
As shown in Figure 1, last plane positioning boring grab is made of clamp body 1, workpiece 2, following rolling center 3, top bearing 4, clamping cam 5 and handle 6; Clamp body 1 be [shape, its entablature has vertical drill bit bore, the entablature lower surface be provided with the location datum level 7; Sill assembling handle 6 and clamping cam 5 clamp top bearing 4 of cam 5 upper units and following rolling center 3.
During operation, at first boring grab is placed on the numerical control drilling machine workbench, adjust the tram of anchor clamps pin-and-hole and bit central, with bolt clamp body 1 is fixed, clean locating surface and following center hole on the workpiece 2, then locating surface on the workpiece 2 is put in the location datum level 7 of clamp body 1, located, the cutting scale on bit location and workpiece 2 surfaces above determining with workpiece 2 upper surfaces; The shaft end center holes are placed on down in the rolling center 3 below the workpiece 2, pull following handle 6 and make and clamp cam 5 and rotate, and clamp cam 5 and promote top bearing 4 and following rolling center 3 clamping work pieces 2 that moves up.After workpiece 2 installs, start lathe boring, the pin-and-hole degree of depth is measured in the boring back, when size reaches 6 ± 0.05mm fixedly drilling machine cut scale.Because last plane positioning boring grab adopts workpiece 2 upper surfaces location, and machining benchmark is overlapped fully with measuring basis, guarantees the workpiece machining accuracy, boring can be satisfied technological requirement.
Claims (2)
1. upper surface location drilling anchor clamps is characterized in that: described anchor clamps by clamp body, down rolling center, top bearing, clamp cam and handle is formed; Clamp body be [shape, its entablature lower surface is provided with the location datum level; Sill assembling handle and clamping cam clamp top bearing of cam upper unit and following rolling center.
2. according to the described upper surface location drilling of claim 1 anchor clamps, it is characterized in that: described clamp body entablature has vertical drill bit bore.
