Specific embodiment
The present invention will be further explained in the following with reference to the drawings and specific embodiments.
As shown in figures 1 to 6, a kind of double cam prepressing device, including pedestal 1, pressing plate 2, probe assembly 3 and cam pressing machine
Structure, pedestal 1 include 11, two blocks of side plates 12 of bottom plate, top plate 13 and backboard 14, and the intermediate hollow out of bottom plate 11 can mitigate the whole of pedestal 1
Body weight, bottom plate 11 are equipped with two pieces of support plates for being used to support pressing plate 2, and two sides side plate 12 is separately positioned on the two of bottom plate 11
The top of two blocks of side plates 12 is arranged in side, top plate 13, and 11, two blocks of side plates 12 of bottom plate, top plate 13 and backboard 14 enclose a box
The structure of shape；Pressing plate 2 is parallel to bottom plate 11, is arranged in pedestal 1, and pressing plate 2 passes through backboard 14 and is fixedly connected on probe assembly 3
Together, probe assembly 3 is arranged on the lateral surface of backboard 14, and the lateral surface of backboard 14 is equipped with guide rail 81, consolidates on probe assembly 3
It is fixed to be equipped with the sliding block 82 cooperated with guide rail 81；The top of pressing plate 2 is arranged in cam pressing mechanism, is fixed on side plate 12, cam
The shaft 41 of hold-down mechanism rotates, and the first cam 42 and the second cam 43 of cam pressing mechanism are successively contacted with pressing plate 2, into one
Step drives probe assembly 3 to move downward, to realize precompressed and crimping movement.It is set between 2 bottom of pressing plate and the bottom plate 11 of pedestal 1
There is spring 21,21 upper end of spring acts against 2 bottom of pressing plate, and lower end is arranged in the support plate of bottom plate 11, during crimping, spring
21 are compressed step by step, after the completion of crimping, realize return by spring 21.
As shown in fig. 7, cam pressing mechanism includes shaft 41, the first cam 42, the second cam 43 and hand in the present embodiment
Handle 5,41 both ends of shaft are each passed through the side plate 12 of two sides, and wherein the side plate 12 of one end stretching side is outer connect with handle 5, and first
Cam 42 and the second cam 43 are arranged between the side plate 12 of two sides, and the radius of turn of the first cam 42 is less than the second cam 43
Radius of turn.Shaft 41 is driven to rotate by handle 5, the first cam 42 is contacted with pressing plate 2 first, drives probe assembly 3 downward
Movement forms precompressed；Shaft 41 continues to rotate, and the first cam 42 is separated with pressing plate 2, while the second cam 43 is contacted with pressing plate 2,
Since the radius of turn of the second cam 43 is greater than the radius of turn of the first cam 42, probe assembly 3 is further moved downward, probe
Component 3 crimps movement with product to be measured completion.
In the present embodiment, the face that the first cam 42 and the second cam 43 are contacted with pressing plate 2 is plane, 42 He of the first cam
When second cam 43 is completely attached to pressing plate 2, it is face contact, can effectively realizes the self-locking of cam pressing mechanism.
41 both ends of shaft are fixed with limited block 44, and the limited block 44 at both ends bears against the side plate in 1 two sides of pedestal
12 insides, limit the axial float of shaft 41, and limited block 44 is rotated together with shaft 41, and limited block 44 is the U-shaped structure of opening,
It is equipped with lock-screw at U-shaped opening, unclamps lock-screw, position of the adjustable limited block 44 in shaft 41.
Handle 5 is vertically arranged with shaft 41, and 41 one end of shaft is inserted into handle 5, and handle 5 connect one end with shaft 41
End face is equipped with adjustment hole 51, and locking screw is screwed into adjustment hole 51, shaft 41 and handle 5 are fixed together；By handle 5
The side plate 12 of side is equipped with gag lever post 6, and when the plane and pressing plate 2 of the second cam 43 completely attach to, handle 5 is against gag lever post 6
On, prevent over-voltage.Locking screw is unclamped, rotational handle 5, shaft 41 will not be rotated together and then at this time, and handle 5 turns to properly
Behind position, locking screw is locked, the rotational angle of adjustable handle 5 adjusts the over-stressed position of the second cam 43.
It is fixed with PCB signal rotating plate 7 on the top plate 13 of pedestal 1, realizes the conversion and transmission of signal.
Product Manual centering is placed on carrier first, rotational handle 5, the first cam 42 contacts pressing plate 2, due to first
The face that cam 42 is contacted with pressing plate 2 is plane, therefore can be very good to contact with pressing plate 2, and unclamp hand and will not be bounced (i.e.
It is self-locking), probe assembly 3 has some distances apart from product test point at this time, and but not is far, observes product orientation by camera
Whether it coincide, can looses one's grip with probe assembly positioning, alignment adjusting is carried out to product and (left and right or more is carried out to product, rotation is adjusted
Section), until product orientation and probe assembly positioning fit like a glove；Handle 5 is continued to rotate, the second cam 43 starts to contact pressing plate 2,
Probe assembly 3 just crimps product test point, signal conduction test at this time, and the plane and pressing plate 2 of the second cam 43 completely attach to
Afterwards, handle 5 is resisted against just on gag lever post 6, and second of formation at this time self-locking, can be loosed one's grip and be carried out other operations；It completes at this time
Afterwards, handle 5 is rotated backward, the return under the action of the spring 21 of pressing plate 2.
Basic principle and key structural feature of the invention has been shown and described above.The present invention is not by the limit of examples detailed above
System, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes and improvements
It both falls in the range of claimed invention.The claimed scope of the invention is by appended claims and its equivalent
It defines.
