Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
A kind of worm screw detection device, including pedestal 1, on pedestal 1 setting two for placing the brackets 2 of worm screw 8, two branch
Movable first probe 42 and the second fixed probe 41, the first probe is respectively set in the two sides of the vertical direction of the line of frame 2
LVDT gauge head 7 is arranged in 42 other end, and LVDT gauge head 7 offsets with the first probe 42 under the force of a spring, the first probe 42
Side connect cam 5, cam 5 connect shaft 6,6 connection traversing mechanism 9 of shaft.
First probe 42 offsets with the worm screw 8, and the second probe 41 can be separated with worm screw 8 under the drive of cam 5 or phase
It supports.
The lower section setting setting lifting cylinder 3 of two brackets 2, bracket 2 pass through pedestal 1；
At least two supports 11 are set on pedestal 1, and when bracket 2 declines, bracket 2 and worm screw 8 are detached from, support 11 and worm screw
8 offset；
It avoids because the stroke of cylinder is different, causes different worm screws 8 to detect height and generate error, by fixed branch
Seat 11 is fixed.
The end of first probe 42 and the second probe 41 setting detection ball, the diameter for detecting ball are less than the axial tooth of worm screw 8
Away from；
That is the first probe 42 and the second probe 41 can be plugged into the tooth of worm screw 8, for detecting the central diameter of worm screw 8.
Connection height different the first strut 12 and the second strut 13, pedestal 1 are obliquely installed below pedestal 1, the second probe
41 offset with worm screw 8；
Since the first strut 12 and 13 height of the second strut are different, pedestal 1 passes through the first strut 12 and the second strut
13 are fixed on slant setting when on other devices, and worm screw 8 under gravity, directly rolls down on the second probe 41 at this time.
Embodiment 1
Rotating mechanism 9 is set as crank and rocker mechanism, including telescopic cylinder, and the output end connecting crank of telescopic cylinder is bent
Handle is connect with shaft 6.
By moving forward and backward for telescopic cylinder, crank is driven to make rotating motion.
Embodiment 2
Rotating mechanism 9 is set as rotary cylinder, and the rotation of shaft 6 is driven by rotary cylinder, and dead point is not present.
Photoelectric sensor 10 is arranged in the line direction of two brackets 2.
Detection process:
Before detection, first a master worm 8 is placed on workpiece and is detected, the result detected is as a reference value, i.e.,
LVDT gauge head 7 is calibrated；
Bracket 2 rises under the action of lifting cylinder 3, and worm screw 8 is placed on bracket 2, and photoelectric sensor 10 detects
Worm screw 8, lifting cylinder 3 are acted, worm screw 8 are put down, until worm screw 8 is jacked up by support 11, bracket 2 is separated with worm screw 8 at this time；
Since pedestal 1 is obliquely installed, worm screw 8 is under self gravity, and the tooth of worm screw 8 offsets with the second probe 41, worm screw 8
Other parts still offset with support 11, i.e., complete positioning by gravity；
Shaft 6 rotates under the drive of rotating mechanism 9, thus with moving cam 5 rotate, cam 5 drive the first probe 42 to
Preceding movement, LVDT gauge head 7 travel forward under the force of a spring, offset always with the first probe 42, since worm screw 8 is rigid
Property, when the first probe 42 and worm screw 8 offset when stop motion, LVDT gauge head 7 compares its size with a reference value, obtains this
The central diameter size of worm screw 8.
The device detects the central diameter of worm screw 8, is calibrated by first measuring a basic worm 8, then to other
The central diameter of worm screw 8 judged that the error of device measurement is small, detected by multiple points, the degree of automation of detection
Height includes the detecting state for judging workpiece, the realization of detection process, and the loading and unloading of detection, and what can be settled at one go is complete
At.
Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model
Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model
It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
