The utility model discloses a milling and drilling dual-purpose modular fixture of a connection rod part. The fixture comprises a fixture body, a dual-positioning cylinder, a double-eccentric wheel, a screw and a force application rod. The dual-positioning cylinder and the double-eccentric wheel are arranged on the fixture body and clamped at the two ends of the connection rod part respectively, one end of the screw is in transmission connection with the force application rod, and the double-eccentric wheel is arranged at the other end of the screw in a sleeved mode. By means of the dual-positioning cylinder and the double-eccentric wheel, a workpiece is positioned and clamped, and clamping of connection rod parts with similar shapes and different sizes can be effectively achieved.

Description

Dual-purpose modular fixture is bored in the milling of connecting rod part
Technical field
The utility model relates to a kind of milling of connecting rod part and bores dual-purpose modular fixture.
Background technology
In the time of the machining of connecting rod workpiece, the location completely that workpiece adopts the setting elements such as support plate, fixing V-block and movable V-block to realize workpiece conventionally, employing activity V-block clamps workpiece as clamping element.V-block has good centering and the advantage such as shape is comparatively simple, but its manufacturing process more complicated, and the production cycle is long, and precision is also not easy to ensure, and in clamp body, install adjust also inconvenient.
Summary of the invention
The purpose of this utility model is the defect existing in prior art in order to solve, provide a kind of to processing without interfere, be easy to adjust bore dual-purpose fixture for connecting rod part milling.
In order to achieve the above object, the utility model provides a kind of milling of connecting rod part to bore dual-purpose modular fixture, comprises clamp body and is located at the support plate on clamp body, also comprises two positioning cylinders, double eccentric wheel, screw rod and force application rod; Two positioning cylinders, double eccentric wheel are located on clamp body, and are held on respectively connecting rod part two ends; Screw rod one end is connected with force application rod transmission; Double eccentric wheel is placed on respectively the other end of screw rod.
Further improvement of the utility model is: above-mentioned fixture also comprises screw bracket; Screw bracket is fixed on clamp body; Screw rod is connected with force application rod through screw bracket.
Clamp body is provided with three groups of pin-and-holes; Double eccentric wheel is by bearing pin one group of pin-and-hole located therein.
Wherein, on clamp body, be also provided with feeler block, facilitate tool setting.
The utility model has the following advantages compared to existing technology: the utility model adopts two positioning cylinders to substitute V-block location, double eccentric wheel replacement activity V-block positioning and clamping, simplified clamp structure, improved fixture anufacturability, realized Workpiece clamping and processing arrange also comparatively flexible without interference capability, dimensional orientation; Positioning cylinder and eccentric wheel all adopt Group Design simultaneously, have adapted to the change in size of connecting rod part, have avoided the design iterations of fixture, have reduced production cost, have improved production efficiency.And for the part of different length size, only double eccentric wheel 5 need be arranged in corresponding pin-and-hole 7 and can be realized the clamping to workpiece by bearing pin 6, thereby effectively reduce the design and manufacture cost of fixture and produce the preparatory period.The utility model adopts two positioning cylinders and double eccentric wheel locating clip clamping of workpieces, can effectively realize the clamping of the connecting rod part that shape is similar, size is different.
Brief description of the drawings
Fig. 1 is the structural representation that dual-purpose modular fixture is bored in the milling of the utility model connecting rod part.
In figure, the two positioning cylinders of 1-, 2-clamp body, 3-workpiece, 4-feeler block, 5-double eccentric wheel, 6-bearing pin, 7-pin-and-hole, 8-screw rod, 9-screw bracket, 10-screw, 11-force application rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, the milling of the utility model connecting rod part is bored dual-purpose modular fixture and is comprised two positioning cylinders 1, clamp body 2, screw bracket 9, screw 10, screw rod 8, force application rod 11, double eccentric wheel 5, bearing pin 6 and feeler block 4.Two positioning cylinders 1 of modular fixture adopt and are threaded with clamp body 2.Screw bracket 9 adopts screw 10 to be connected with clamp body 2.The right-hand member of screw rod 8 is connected with force application rod 11 through screw bracket 9.Double eccentric wheel 5 is set in the left end of screw rod 8, and is arranged on by bearing pin 6 in the pin-and-hole 7 of clamp body 2.Clamp body 1 is provided with three pairs of pin-and-holes 7, and the installation site of being convenient to double eccentric wheel 5 adapts to different length set of dimensions connecting rod part.Feeler block 4 adopts and is threaded on clamp body 2, can facilitate tool setting.
The utility model operation principle is: first according to the connecting rod part of required processing (workpiece 3) positioning datum (small end cylindrical) size, and the two positioning cylinders 1 of design processing; According to the large end excircle dimension of connecting rod part, the installation site of design processing double eccentric wheel 6(double eccentric wheel is depending on connecting rod part length dimension group).Then on support plate (not shown) and two positioning cylinder 1, complete pre-determined bit with end face and the small end cylindrical of connecting rod workpiece 3.The force application rod 11 that turns clockwise, is moved to the left screw rod 8, drives double eccentric wheel 5 to rotate around bearing pin 6, makes double eccentric wheel 5 workpiece pressings 3, completes location and the clamping of workpiece simultaneously.
If this modular fixture is in order to milling connecting rod part end face, need two directional bond (not shown)s be installed in clamp body 2 bottom surfaces and determine the position of jig on milling machine table, put at the ear seat of clamp body 2 by bolted on milling machine table, and feeler block 4 is installed; If in order to the hole of drilling connecting rod part, need be on clamp body 2 installing drill mould holder, bushing plate and drill bushing (all not shown in figure).When workpiece completes after the processing in end face or hole, unscrew counterclockwise force application rod 11, screw rod 8 is moved right, drive double eccentric wheel 5 to rotate around bearing pin 6, workpiece is unclamped, can realize freely loading and unloading of workpiece.In the time that the length dimension group of workpiece changes, only double eccentric wheel 5 need be arranged in corresponding pin-and-hole 7 by bearing pin 6.This modular fixture is as fraise jig, fraise jig is determined the position of jig on milling machine table to adopt screw (not shown) to be connected to two following directional bond (not shown)s of clamp body 2 bottom surfaces, and puts at the ear seat of clamp body 2 by bolted on milling machine table; This modular fixture, as drill jig, only need install drill jig support, bushing plate and drill bushing (all not shown in figure) additional on clamp body 2.
The utility model adopts two positioning cylinders and double eccentric wheel to replace respectively fixing V-block and movable V-block as setting element and clamping element, simplify clamp structure, improve fixture anufacturability, realized Workpiece clamping and processing without interference capability, avoid the design iterations of fixture, reduce production cost, improved production efficiency, ensured the crudy of part.
