In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
On the one hand, the invention provides a quick screw production changing tool, as shown in fig. 1-4, which comprises a base 1, wherein a rotating shaft 2 is arranged in the middle of the base 1, a screw fixing turntable 3 is arranged at the upper end of the rotating shaft 2, and a ratchet wheel 4 is arranged at the lower end of the rotating shaft 2, wherein:
The screw fixing turntable 3 is round, but not limited to, and can also be elliptical, square or any other shape, a plurality of screw placing hole sites 5 are uniformly arranged around the screw fixing turntable, the screw placing hole sites 5 are respectively used for placing screws with different specifications (namely, according to each screw with different specifications, the screw placing hole sites corresponding to the screw placing hole sites are specially designed), the screw placing hole sites 5 are designed so that after the screws with different specifications are placed in the corresponding screw placing hole sites 5, the circle centers of screw caps of the screws with different specifications are on the same circle (taking the center of the screw fixing turntable 3 as the circle center) and the top ends of the screw caps are on the same plane, thus, when the screws are identified in the same batch, the screw placing hole sites 5 can be ensured not to be askew, the product consistency is good, and even when the screws are replaced, the whole tool is not required to be moved and adjusted, the screw placing hole sites 5 are only required to be switched by rotating the screw fixing turntable, so that the screws are enabled to be positioned at the same position (the same height) after the screws are placed, the basis is not required to be adjusted again, and the laser marker is provided for realizing quick replacement batch production;
The ratchet wheel 4 is uniformly provided with a plurality of ratchets 7, the number of tooth grooves 8 (tooth grooves are formed between adjacent ratchets) of the ratchets 7 is the same as the number of screw placement hole sites 5, so that the screw fixing turntable 3 can be driven to rotate by rotating the ratchet wheel 4, the screw placement hole sites 5 can be known to rotate by the same number/angle through the number/angle of the tooth grooves 8, and the screw placement hole sites 5 can be conveniently switched and selected;
The base 1 is provided with a positioning device 9 for fixing the ratchet wheel position on the side surface of the ratchet wheel 4, and after the screw placement hole position 5 on the screw fixing turntable 3 is selected, the position of the ratchet wheel 4 can be fixed through the positioning device 9, so that the position of the screw fixing turntable 3 is indirectly fixed.
In the invention, the screw placement hole site preferably adopts the following two structural forms:
Structural form one:
As shown in fig. 1, the screw placement hole site 5 is a radial U-shaped opening 51, the width of the U-shaped opening 51 is adapted to the diameter of the shank of the screw of the corresponding specification (the shank is equal to or slightly larger than the shank to facilitate placement), the innermost side of the U-shaped opening 51 is provided with a groove 52, and the shape of the groove 52 is adapted to the shape of the nut of the screw of the corresponding specification.
The embodiment shown in fig. 1-4 uses this first embodiment. Specifically, the lengths of the U-shaped openings 51 and the positions (mainly referred to as vertical positions) of the grooves 52 can be designed, so that after screws with different specifications are placed in the grooves 52 of the corresponding U-shaped openings 51, the circle centers of the nut caps of the screws with different specifications are on the same circle and the top ends of the nut caps are on the same plane.
And the structural form II is as follows:
The screw placing hole positions are related structures that the screw bodies of screws with corresponding specifications penetrate through the reducing through holes for only accommodating the screw caps, namely, the opening parts are removed on the basis of the U-shaped opening 51 shown in fig. 1, and only the innermost grooves 52 are reserved.
At this time, after screws of different specifications are placed in the corresponding reducing through holes, the circle centers of the nut caps of the screws of different specifications are on the same circle and the top ends of the nut caps are on the same plane by designing the positions and the shapes of the reducing through holes.
It is conceivable that, based on the above structural forms, the person skilled in the art may also design the screw placement hole site into other possible structural forms, which are not described here again.
When the screw quick-change tool is used, as shown in fig. 4, an operator can search a screw placement hole position 5 corresponding to the screw placement hole position on the screw fixing turntable 3 according to the screw 10 which is required to be marked, and then manually control the ratchet wheel 4 to rotate to drive the screw fixing turntable 3 to rotate so as to switch the screw placement hole position 5, so that the screw 10 is positioned right above the marking position 11, and quick-change is realized.
The application method of the screw quick production changing tool can be specifically referred to as the following steps:
S1, fixing: placing the tool on a laser marking machine, specifically, arranging a mounting hole on a base, and fixing the base on the laser marking machine through a bolt;
S2, determining hole sites: determining which screw placement hole position on the tool corresponds to the screw to be marked according to the job ticket;
s3, placing a screw: placing the screws into corresponding screw placement hole sites and straightening;
s4, debugging program: after the placement of the screws, the X, Y, Z axial direction of the laser marking machine is respectively adjusted (after the first adjustment, the adjustment is not needed again when the batch and the production are changed, and the screw fixing turntable is rotated to the hole position corresponding to the screws);
s5, marking and confirming: calling an identification template corresponding to the screw, starting a laser marking machine to perform laser marking, confirming the marking effect, manually taking down the marked screw, replacing the same batch of other screws, and continuing marking;
S6, changing batch and production: and determining that the screw to be marked corresponds to a screw placement hole position on the tool according to the job ticket, adjusting the rotation angle of the screw fixing turntable according to the hole position, and repeating the operation of the step S5 to realize batch and product replacement.
The quick screw production changing tool is simple in structure, short in processing period, high in positioning accuracy and low in cost; when carrying out same screw sign, every time when changing the screw, the hole site is placed to the screw can both guarantee that the screw does not take place askew, and the product uniformity is good, and even when changing the batch, need not to remove and adjust whole frock, only need to drive the screw fixed carousel through the ratchet and rotate and switch the screw and place the hole site, can guarantee that the screw is in the same position (highly also the same) after placing, need not to adjust laser marker again, consequently, this frock can realize quick change, reduces and changes batch and change the time of producing, improves production efficiency, guarantees the uniformity of every batch of product, promotes product quality.
In the present invention, the number of the screw placement holes 5 on the screw fixing turntable 3 may be 2 to 30, preferably 10 to 20 (20 in the embodiment shown in the drawings). Preferably, the positions of the screw placement hole sites 5 and the tooth sockets 8 are in one-to-one correspondence, so that the selection of the screw placement hole sites 5 is more convenient.
In order to realize firm fixation of the screw fixation turntable 3 and the ratchet wheel 4, as shown in fig. 2, shaft and key fixation modes are adopted between the screw fixation turntable 3 and the rotating shaft 2 and between the ratchet wheel 4 and the rotating shaft 2.
