Abstract
A screw holder of an automatic screw fastening machine is characterized in that the screw holder comprises a main body block (1) with a screwdriver inserting hole (14) at the center thereof; two sides of the main body block (1) are axially connected with symmetrical clamping jaws (2); a spring (3) is arranged between each jaw (2) and the main body block (1); the lower ends of the two symmetrical jaws (2) are close to a screw placing hole (10) formed with an inclined surface (11); the side edge of the main body block (1) is provided with an inclined hole (8) which is communicated with the screwdriver inserting hole (14); the main body block is provided with a movable block (6) axially connected with the main body block (1) at a position opposite to the inclined hole (8); a tension spring (5) is arranged between the movable block (6) and the main body block (1); and the movable block (6) is provided with an inclined edge (9) matched with the inclined hole (8). The screw holder has the advantages of flexible and reliable holding action, smooth screw feeding, no over-turn and no blocking, improves the working efficiency and reduces the processing cost of workpieces.
Description
Technical field
The utility model relates to the screw clamping device of the fastening machine of a kind of automatic screw.Be used for fastening screw when being used for the work of the fastening machine of the automatic screw of clamping.
Background technology
Often need connect or each part of fixed product in the industrial production by screw.Traditional fastening means is fastening one by one by the human screwdriver.Because the restriction of working method, fraction defective is higher, wastes time and energy to be unfavorable for large-scale production.
When the fastening machine of existing automatic screw is sent into the screw clamping device on the market after screw is separated; because the problem of structure has screw often and is stuck in the fault that clamping device causes work to stop; especially short screw, because may in the supply process, overturn, this type of fault of easier generation.
Summary of the invention
The purpose of this utility model provides the automatic screw fastening machine screw clamping device of a kind of screw in reliable, smooth and easy, the no stuck phenomenon of fastening front clamp flexible movements, high efficiency, overcomes the deficiencies in the prior art.
The fastening machine screw clamping device of automatic screw of the present utility model, it is characterized in that: comprise that the center has the main body block 1 of screwdriver patchhole 14, be connected with the jaw 2 of symmetry at two side shafts of main body block 1, be provided with spring 3 between each jaw 2 and the main body block 1, the nearly screw placement hole 10 that has inclined-plane 11 that forms of the low side head rest of the jaw 2 of two symmetries, being provided with inclined hole 8 at the side of main body block 1 is connected with screwdriver patchhole 14, the opposite that is positioned at inclined hole 8 on main body block 1 is provided with and 1 movable block that is connected 6 of main body block, be provided with extension spring 5 between movable block 6 and the main body block 1, movable block 6 is provided with hypotenuse 9 and matches with inclined hole 8.
The fastening machine screw clamping device of automatic screw of the present utility model compared with prior art, because the symmetrically arranged jaw of expansible, merging is arranged, and the jaw inboard is provided with the inclined-plane, is furnished with the movable block of being with hypotenuse mutually with the inclined hole that screw enters, make inclined hole and the screwdriver patchhole place of being connected form the screw entrance hole of standard, so have holding action flexibility and reliability, screw enter smooth and easy, do not overturn, not stuck advantage, improved operating efficiency, reduced the processing cost of workpiece.
Description of drawings
Fig. 1 is the contour structures schematic diagram of the utility model specific embodiment;
Fig. 2 is the main cross-sectional schematic of the utility model specific embodiment;
Fig. 3 is an A-A cross-sectional schematic shown in Figure 1;
Fig. 4 is the structural representation behind movable block 6 rotational angles shown in Figure 3.
The specific embodiment
As shown in the figure: 1 is main body block, centerline in main body block 1 is processed with screwdriver patchhole 14, both sides in main body block 1 are connected with two symmetrically arranged jaws 2 with rotating shaft 4, between the upper end of each jaw 2 and the main body block 1 spring 3 is installed, spring 3 leans two jaws 2, make the low side of jaw 2 close, the low side of jaw 2 forms the screw placement hole 10 that has inclined-plane 11 near the back.
Be positioned on the main body block 1 with perpendicular of two jaws, 2 place faces on side edge be processed with inclined hole 8, inclined hole 8 and the main body block 1 cutter patchhole 14 of tightening up a screw is connected.
The opposite that is positioned at inclined hole 8 on main body block 1 is connected with movable block 6 with rotating shaft 12, is fixed with hanging scroll 7 on the movable block 6, is mounted with extension spring 5 between hanging scroll 7 and the main body block 1, and extension spring 5 makes movable block 6 be in the inboard of main body block 1.Be processed with hypotenuse 9 on the movable block 6 and match, make inclined hole 8 and duct, spiral shell cutter patchhole 14 intersection standard, the variation of spatial form does not take place with inclined hole 8.
This clamping device and reciprocating mechanism join during installation, and the port of inclined hole 8 gas-tpe fitting 15 that has been threaded joins by gas-tpe fitting 15 and pneumatic screw feeding device.Screw is after inclined hole 8 enters, enter screw smoothly and go into to put hole 10, screw cap is held up by inclined-plane 11, screwdriver inserts from screwdriver patchhole 14 then, this clamping device moves down simultaneously, movable block 6 is stopped by pin 13 and turn an angle (as Fig. 4), avoid screwdriver patchhole 14, driver tip can contact with screw cap and rotate, screw precession workpiece is tightened, in the screw precession, owing on the jaw 2 inclined-plane 11 is arranged, two jaws 2 can simultaneously stressedly open with screw and break away from, and jaw 2 open while springs 3 are compressed.
