The detection head assembly of electromagnetic valve body screw thread test machine
Technical field
The present invention relates to field of machinery automation, more particularly to the detection head assembly of solenoid valve valve deck screw thread test machine.
Background technology
In portable electronic device (such as mobile phone, personal digital assistant) production process, need through screw, screw etc.
Fastener fits together multiple workpiece.The helicitic texture of setting and the appended claims on each workpiece, before assembling
It needs to carry out screw thread specification detection to the workpiece with the helicitic texture.Common detection method is the survey that test man advises a tooth
Examination end rotates into and exits the helicitic texture to judge whether the helicitic texture is qualified, however needs that detects to be threaded knot
The piece count of structure is often more, and Detection task is heavy.Operator is due to manual operation, and the efficiency examined is very low, nothing
The precise information of method offer measurement, man's activity are larger.

Description of the drawings
Fig. 1 is the structural schematic diagram of the detection head assembly of electromagnetic valve body screw thread test machine of the present invention.
Specific implementation mode
Present pre-ferred embodiments are described in detail below in conjunction with the accompanying drawings, so as to can be more easy to feature the advantages of invention
In being readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
As shown in Figure 1, the detection head assembly includes the be fixedly connected with the first detector guide shaft support lower end
One detection is fixedly connected with ring 4118, and the lower face that the first detection is fixedly connected with ring 4118 is fixed with the first detector ladder by pin
Shaft stool 4119 is equipped with the first detector multi-diameter shaft in the positioning sleeve of the lower face of first detector ladder shaft stool 4119
41111, and position and be cased with an inclined-plane;First detector multi-diameter shaft 41111 is consolidated by bolt by the first detection locating piece 41112
Fixed, the first detection locating piece 41112 has an inclined-plane;The inclined-plane and the first detector ladder of the first detection locating piece 41112
Agree with mutually on the inclined-plane of 4119 lower face positioning sleeve of shaft stool;First detector multi-diameter shaft, 41111 lower semisection is internally provided with peace
Fill counterbore;Key is equipped with the axle center trisection of the first detector multi-diameter shaft 41111 on the outer wall of first detector multi-diameter shaft 4111
Slot, mounting hole, mounting hole is located at the top of keyway and mounting hole is communicated with installation counterbore;In first detector multi-diameter shaft 41111
It is interspersed with the first detector 41113 of shaft-like in the installation counterbore in portion, the lower part of the first detector 41113 is equipped with downwards the successively
One detection no-go gage 41114 and first detects drift 41115;Equipped with the first detection key 41116, the first detection key in the keyway
First the second connecting rod of detection 41117, the first detection 41117 other end pin joint first of the second connecting rod inspection are connected on 41116
Head rod 41118 is surveyed, the other end of the first detection head rod 41118 is connected to the first detector ladder by pin joint
Holder on 4119 lower surface of shaft stool;First the second connecting rod 41117 of detection is equipped with a sliding slot, and first is connected in sliding slot
Fixed block 41119 is detected, the other end of the first detection fixed block 41119 is inserted into the peace on 41111 surface of the first detector multi-diameter shaft
Hole is filled, the thickness of the first detection fixed block 41119 is more than the thickness of 41111 inner hole wall of the first detector multi-diameter shaft;First detection
4119 lower surface of head ladder shaft stool and 41111 surface of the first detector multi-diameter shaft are connected with the first detection spring 411111.
When in use, when detector 41113 needs replacing, the bolt first detected on locating piece 41112 unclamps, this
When, the first detection spring 411111 is elongated by the weight of the first detector multi-diameter shaft 41111, at this time first the second connection of detection
First detection fixed block 41119 of 41117 end pin joint of bar will be extracted from mounting hole, and clamped detector 41113 is released
It decontrols and, then detector to be used will be needed to insert into the installation counterbore of the first detector multi-diameter shaft 41111, it thereafter, will
First detector multi-diameter shaft 41111 is moved upwards up to the inclined-plane and the first detector multi-diameter shaft branch of the first detection locating piece 41112
The inclined-plane of 4119 lower face positioning sleeves of seat agrees with mutually, and the first detection is bolted with the first detection fixed block 41119
First detection fixed block 41119 is inserted into mounting hole and withstands detector 41113, detector 41113 is pressed from both sides by head multi-diameter shaft 41111
It fastens.
A kind of detection head assembly of electromagnetic valve body screw thread test machine provided by the invention, the test machine can be detected accurately
Thread size, high degree of automation save labour.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
