Detailed description of the invention
In order to make those skilled in the art better understand technical scheme of the present invention, below in conjunction with specific embodiment, this programme is further detailed.
With reference to figure 1, the snap ring neglected loading that the embodiment of the present invention provides detects frock, comprise base 1, the both sides that described base 1 is relative are fixed with frock main body 2 and locating piece 3 respectively, described locating piece 3 coordinates with the centre bore of workpiece to be detected, is also provided with the detection block 4 moved upward after abutting with snap ring between described locating piece 3 with described base 1; Described frock main body 2 is provided with central through hole 21, is fixed with sensor 5 in described central through hole 21, and described sensor 5 is electrically connected with outside display instrument (not shown); The carriage release lever 6 that can move in described central through hole 21 is also provided with in described central through hole 21, the bottom of described carriage release lever 6 is fixedly connected with described detection block 4, the termination that described carriage release lever 6 is connected with described detection block 4 can be set to threaded rod, fixes by nut and described detection block 4.Described carriage release lever 6 has motion top dead centre, and its top just contacts with described sensor 5 when described top dead centre.
During detection, first described locating piece 3 is inserted in the centre bore of workpiece A, if described workpiece A is equipped with snap ring B, detect block 4 to abut with described snap ring B, stressed rear described detection block 4 moves upward thus drives connected carriage release lever 6 to move upward together, when described carriage release lever 6 moves to top dead centre, just contact with sensor 5, trigger described sensor 5 and produce signal, and pass to outside display instrument, outside display instrument can show and assembles snap ring; If the described snap ring B of neglected loading on described workpiece A, then described locating piece 3 can not drive described carriage release lever 6 to move upward, described sensor 5 can't detect signal, and snap ring is not installed in outside display instrument display.
In order to strengthen the warning function in neglected loading snap ring situation, also can be provided with the alarm lamp be connected with sensor electrical and/or buzzer, when sensor can't detect signal, alarm lamp and/or buzzer warning, remind operating personnel to note.
In the present embodiment, described detection block 4 comprises top board 41 and the many groups circumferentially fixing claws 42 along described top board 41, the lateral surface often organizing described claw 42 is respectively equipped with the projection 43 for abutting with snap ring.Described claw 42 is preferably three groups, and the circumference along described top board 41 is evenly arranged.Described locating piece 3 is provided with organize with described claw 42 one_to_one corresponding and the chute 31 of slip clamping more.The setting of described projection 43, makes to detect when block 4 contacts with snap ring and can not interfere with described locating piece 3; And described detection block 4 selects slip snap-fit engagement with described locating piece 3, facilitates being connected and fixed of described detection block 4.
Further, described base 1 is preferably the framework of semi-surrounding structure, and it has an accommodation space, and described locating piece 3 and described detection block 4 are all positioned in described accommodation space, thus can save space, make the structure of whole frock compacter.
On this basis, described locating piece 3 can be connected with the side sidewall bolt of described base 1; The top of described base 1 also can be connected with described frock body 2 bolt.
Selectively, described base 1 also can be block structure, fixes a connecting rod bottom it, and described connecting rod is fixedly connected with the top of described locating piece 3, and described detection block 4 is sleeved on described connecting rod slidably.
On the basis of this enforcement technique scheme, described central through hole 21 is preferably stepped hole, comprises the first through hole and the second through hole, and described first through hole is near described base 1, and the diameter of described first through hole is less than the diameter of described second through hole; And described carriage release lever 6 is provided with to coordinate with the step surface of described stepped hole and move downward described carriage release lever 6 and carries out spacing positive stop lug boss 61, described carriage release lever 6 is made to possess a motion lower dead center, prevent under non-detection status, it is long that described carriage release lever 6 stretches out described frock body 2, and drive described locating piece 3 and described detection block 4 excessive apart from the distance of described base 1, tool structure is not compact.
Preferably, described carriage release lever 6 is also set with return spring 7, described return spring 7 is between described positive stop lug boss 61 and the upper limit structure 8 of described carriage release lever 6.When detecting, described carriage release lever 6 moves upward, and described return spring 7 is compressed, and after detection, relies on the deformation power of described return spring 7, and described carriage release lever 6 is returning quickly automatically.
In order to avoid carriage release lever 6 moves repeatedly wearing and tearing are caused to described frock body 2, at the position that described central through hole 21 aperture is less, namely in described first through hole, be also provided with described carriage release lever 6 matched in clearance without oily lining 9.
In the part that described central through hole 21 aperture is larger, namely in described second through hole, be also fixed with back-up block 10, described support fixture block can be the rectangle frame structure of hollow, described carriage release lever 6 is arranged through described back-up block 10, and described upper limit structure 7 is for being arranged on the boss of described back-up block 10.Described back-up block 10 facilitates the setting of described upper limit structure 7, avoids on the hole wall of described central through hole 21, directly process position limiting structure and causes processing inconvenience.
The bottom of described back-up block 10 preferably contacts with the step surface of described central through hole 21, and is provided with lower gasket 13 between described back-up block 10 and described central through hole 21, to improve fixing fixing.
Further, the top of described back-up block 10 is fixed with sensor stand 11, and described sensor stand 11 is preferably L-type support, to alleviate the weight of support as far as possible.The side sidewall of described l type support and the hole wall of described second through hole are adjacent to fixing, described sensor 5 is fastened on this sidewall by screw, the opposite side sidewall of described L-type support is arranged near the top of described frock body 2, it offers through hole, and the wire harness for described sensor 5 passes.
In addition, the top of described frock main body 2 is also provided with end cap 12, and described end cap 12 can be threaded with described frock main body 2.Described end cap 12 is also provided with the limiting through hole 121 supplying the wire harness of described sensor 5 to pass through, the wire harness of described sensor 5 is had to the effect of spacing guiding.
The bottom of described end cap 12 and the tip contact of described sensor stand 11, and be provided with upper gasket 14 between the two, firm to ensure overall structure installation.
