The specific embodiment
Be described further with regard to the technical solution of the utility model below in conjunction with drawings and the specific embodiments.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Referring to figs. 1 through Fig. 4, Fig. 1 is the structural representation that the utility model automatic locking is paid the screw device preferred embodiment; Fig. 2 is the sectional structure schematic diagram that the utility model automatic locking is paid the screw device preferred embodiment; Fig. 3 is the structural representation of criticizing the mouth chuck shown in Figure 1; Fig. 4 is that the utility model automatic locking is paid the sectional structure schematic diagram of screw device when in running order; Fig. 5 is that the utility model uses automatic locking to pay the structural representation that screw device is used for installing the product of screw hole.
In the present embodiment, a kind of automatic locking is paid screw device, comprises batch mouth body 10, batch mouth chuck 20 and batch pin 30.Criticize mouth chuck 20 and comprise the right and left, but folding connects.Automatic locking is paid and is offered an axial centre bore 11 of paying screw device through automatic locking on screw device, and wherein, batch pin 30 moves up and down in centre bore 11.In addition, criticizing both sides on mouth body 10 also offers the groove (not shown) and can be installed on wherein for batch mouth chuck 20 of the right and left.Particularly, criticize the locating hole (not shown) that offers on mouth body 10 through groove, criticize accordingly and offer pin hole 21 on mouth chuck 20, pass locating hole and pin hole 21 by pin 40 and will criticize mouth body 10 and be flexibly connected with batch mouth chuck 20, and batch mouth chuck 20 is resetted when open on batch mouth chuck 20 both sides by spring 50.In addition, automatic locking is paid screw device and is also comprised trachea 80, and trachea 80 is communicated with centre bore 11, and trachea 80 is connected with automatic device for feeding screw.At first, after automatic device for feeding screw is good with arranging screws, by trachea 80, screw is blown in centre bore 11 one by one.Head at batch mouth chuck 20 offers for screw 60 is carried out spacing spacing hole 22.In the present embodiment, preferred spacing hole 22 is internal diameter bellmouth wide at the top and narrow at the bottom.In the present embodiment, the degree of depth of spacing hole 22 is 10mm.Criticize pin 30 and specifically comprise batch shank body 31 and screwdriver bit 32, screwdriver bit 32 is adaptive with the shape of the screw terminal of screw 60.Lock is during screw 60, screwdriver bit 32 aimed at and inserted in the locating slot of offering on the screw terminal of screw 60, and the utility model is not construed as limiting at this.
This automatic locking is paid screw device when work, and the spacing hole 22 of at first automatic locking being paid screw device is aimed at the screw hole 70 on the product that needs to install screws 60.Then the air blowing type filature is blown into screw 60 in the locating hole of batch thorax in batch mouth body 10 by trachea 80, move down by batch pin 30 screw 60 is applied the power that moves downward, thereby screw 60 moves down and backs down batch mouth chuck 20, and the guide effect by spacing hole 22, spacing so that screw 60 is carried out in the process that falls into screw hole 70, make screw 60 keep not deflection.Thereby driven by motor is criticized shank body 31 and rotated relative screw hole 70 rotations of drive screw 60 subsequently, thereby with screw 60 lockings.
The automatic locking that the utility model proposes is paid screw device, because the head of described batch of mouth chuck 20 is provided with spacing hole 22, the state of can being kept upright when making screw 60 be blown in batch thorax in batch mouth body 10 by the air blowing type filature, thereby prevent screw 60 deflections, thereby the lock of realizing the deep hole screw is paid, and also improves the positioning accuracy of screw 60 simultaneously.
Preferably, batch pin 30 is provided be used to the magnet (not shown) that holds screw 60, and in the present embodiment, screwdriver bit 32 is preferably 5cm apart from the distance of magnet.Because of the deep hole screw in locking process, screw 60 is very large apart from the distance of screw hole 70, at this moment, by being provided be used to the magnet that holds screw 60 on batch pin 30, make screw 60 batch pin 30 in the process that falls into screw hole 70 can hold screw 60, thereby make screw 60 can not fall into separately screw hole 70, but send in screw hole 70 by criticizing pin 30, avoided issuable screw 60 positions skews and caused accurately to drop in the screw hole 70 of appointment.
Particularly, spacing hole 22 is internal diameter bellmouth wide at the top and narrow at the bottom.In the present embodiment, the degree of depth of spacing hole 22 is 10mm, and the size of spacing hole 22 internal diameter minimums is than the large 0.5mm of lead screw diameter of screw.
Further, criticize the radius of shank body 31 greater than the radius of screwdriver bit 32.Existing automatic locking is paid in screw device, the radius of criticizing shank body 31 equals the radius of screwdriver bit 32, like this, when batch shank body 31 pushing screws 60 move downward, the screw terminal of screw 60 will be criticized mouth chuck 20 and back down, when screw terminal backs down batch mouth chuck 20, can make because of the reaction force that batch 20 pairs of screws 60 of mouth chuck apply screw 60 occur being offset, thus the positioning accuracy when affecting screw 60 and falling into screw hole 70.In the present embodiment, the radius of batch shank body 31 is greater than the radius of screwdriver bit 32, like this, after screwdriver bit 32 and screw terminal chucking, contacts and will criticize mouth chuck 20 and push open with criticizing mouth chuck 20 by batch shank body 31, then screw sent in the screw hole 70 on the housing of product.To criticize mouth chuck 20 by batch shank body 31 and push open, and can avoid coping screw 60 to push batch mouth chuck 20 open and the screw 60 that causes tilts, and reduce screw 60 issuable crooked, thereby further improve the positioning accuracy of screw 60.
Further, criticize the top that mouth chuck 20 is positioned at spacing hole 22 and offer the up-narrow and down-wide taper counterbore 23 of internal diameter.Screw 60 falls into when criticizing mouth body 10, the screw terminal of screw 60 and taper counterbore 23 butts, the stressed mouth chuck 20 of criticizing of the screw terminal of screw 60 is pushed open, begin rotation when batch pin 30 is stressed, and screw terminal not be also will criticize mouth chuck 20 and push open the time, be undertaken spacingly by 23 pairs of screws of taper counterbore 60, guarantee to make the screw terminal of screw 60 not crooked, thereby guarantee that screwdriver bit 32 aims at the locating slot on the screw terminal of screws 60, and then further improve the positioning accuracy of screw 60.
Further, criticize the head of mouth body 10 and be positioned at spacing hole 22 belows and offer guide cylinder 12.The internal diameter of guide cylinder 12 is than the large 0.5mm of diameter of the screw terminal of screw 60, and the height of guide cylinder 12 is 8mm.Like this, make screw 60 drop to around when outlet still limited location, thereby prevent that unsettled screw 60 from swinging, thereby the deflection of automatic calibration screw 60 guarantees alignment.
The utility model further also proposes a kind of automatic locking screw machine, and this automatic locking screw machine comprises that automatic locking pays screw device, and automatic locking is paid screw device with reference to above-described embodiment, does not repeat them here.
The automatic locking screw machine that the utility model proposes, by on the head of described batch of mouth chuck, spacing hole being set, the state of can being kept upright when making screw be blown in batch intrinsic batch of thorax of mouth by the air blowing type filature, make the screw can deflection, thereby the lock of realizing the deep hole screw is paid, and also improves the positioning accuracy of screw simultaneously.
The above is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
