Abstract
The utility model discloses a kind of tractor crankshaft pocket watch, described tractor crankshaft pocket watch comprises clock-type amesdial, amesdial housing screw, tappet, spiral compression spring, bar cover and semi-circular arc road detection and location part; Described tappet is externally connected with described spiral compression spring, and described spiral compression spring overcoat has described bar cover; Described semi-circular arc road detection and location part is connected with the termination of bar cover away from clock-type amesdial one end; Described tappet is made up of tappet upper boom and tappet lower beam; Described clock-type amesdial is connected with tappet upper boom, and tappet upper boom is connected with tappet lower beam one end, and the other end of described tappet lower beam is provided with and detects termination.Compared with the existing, the tractor crankshaft pocket watch of the utility model protection can see the actual size of product work in-process very intuitively, processes accurately, and measures accurately.
Description
Technical field
The utility model relates to a kind of tractor crankshaft pocket watch.
Background technology
Automobile crane is the vital part of automobile engine, and required precision is very high, generally all within several micron.Past is all adopt micrometer to measure when refining.And the precision of micrometer is decimillimeter level, can not meet product requirement at all; In addition, during measurement, must grinding be stopped, exiting emery wheel, could measure after product stops operating, consuming time many and belong to and measure afterwards.Operator can only add cutter adding man-hour on a small quantity, repeatedly shuts down, measures.Require high to operator, work efficiency is low.
Utility model content
The purpose of this utility model is just to provide a kind of tractor crankshaft pocket watch, and this tractor crankshaft pocket watch can see the actual size of product work in-process very intuitively, processes accurately, and measures accurately.
The technical solution of the utility model is: a kind of tractor crankshaft pocket watch, and described tractor crankshaft pocket watch comprises clock-type amesdial, clock-type amesdial housing screw, tappet, spiral compression spring, bar cover and semi-circular arc road detection and location part; Described tappet is externally connected with described spiral compression spring, and described spiral compression spring overcoat has described bar cover; Described semi-circular arc road detection and location part is connected with the termination of bar cover away from clock-type amesdial one end; Described tappet is made up of tappet upper boom and tappet lower beam; Described clock-type amesdial is connected with tappet upper boom, and tappet upper boom is connected with tappet lower beam one end, and the other end of described tappet lower beam is provided with and detects termination.
As preferably, described semi-circular arc road detection and location part is provided with the first auxiliary gauge head and the second auxiliary gauge head.
As preferably, described second auxiliary gauge head is arranged on the semi-circular arc road end of detection and location part in semi-circular arc road away from one end of described tappet, and the described first auxiliary gauge head is arranged on the point midway in the semi-circular arc road of described semi-circular arc road detection and location part.
The utility model beneficial effect is:
One be the utility model become passive measurement be Active measuring.
Two is ensure that product processing quality.Operator can see the actual size of product work in-process very intuitively, processes accurately.
Three is improve work efficiency greatly.The utility model avoids shutdown repeatedly, effectively raises work efficiency.
Four are reduction of the requirement to operative skill.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of tractor crankshaft pocket watch as shown in Figure 1, comprises clock-type amesdial 1, amesdial housing screw 2, tappet, spiral compression spring 7, bar cover 6 and semi-circular arc road detection and location part.Tappet connects spiral compression spring 7 outward, and spiral compression spring 7 overcoat has bar to overlap 6.Semi-circular arc road detection and location part and bar overlap 6 and are connected away from termination, clock-type amesdial 1 one end.
Tappet is by tappet upper boom 8 and tappet lower beam 5.
Clock-type amesdial 1 is connected with tappet upper boom 8, and tappet upper boom 8 is connected with tappet lower beam 5 one end.The other end of tappet lower beam 5 is provided with and detects termination.
Detection and location part in semi-circular arc road is provided with the first auxiliary gauge head 3 and the second auxiliary gauge head 4.Second auxiliary gauge head 4 is arranged on the semi-circular arc road end of detection and location part in semi-circular arc road away from one end of tappet lower beam 5, and the first auxiliary gauge head 3 is arranged on the point midway in the semi-circular arc road of semi-circular arc road detection and location part.
The utility model adopts micron-sized clock-type amesdial 1 as survey tool, meets product requirement from certainty of measurement.Extended the measuring stick of clock-type amesdial 1 by bar cover 6, tappet upper boom 8, tappet lower beam 5, then directly act on the measuring point of part to be processed by the first auxiliary gauge head 3 and the second auxiliary gauge head 4, directly measure in product processing.The utility model is vertically suspended on emery wheel front by leverage when using, and operator can measure at any time very easily in process.
