Description
Technical field
The invention belongs to the fastening apparatus technical field, particularly the device on workpiece by screw fastening.
Background technology
In the production assembling processes such as machinery, electronics, the firm situation of screw is more, generally adopt bottle opener or electric spiral shell cutter to carry out, development along with technology, the structural change of screw fastening device is many, and the function possessed is also more and more, discloses a kind of screw fastening device as Chinese patent CN200920010417.0, this device realized laterally, vertically and the mechanical action on vertical, the spiral shell cutter head can reach each position of workpiece.But in these prior aries, mostly the robust means once-through operation can only a firm screw, when for same work top, needing fastening many symmetrical screws, need operate one by one, this mode not only efficiency is low, and the firmness degree of each screw is difficult to be consistent.
Summary of the invention
The problem existed for solving prior art, the invention provides a kind of screw fastening device, realized fastening two functions with screwing of while on same work top, improved efficiency.
Technical scheme of the present invention is as described below:
A kind of screw fastening device, mainly by electric spiral shell cutter, upper buckle, axle, lower pinch plate, driving gear, control loop and fastening assembly form, upper buckle, lower pinch plate connects the formation cavity with control loop, axle passes cavity and is arranged on cavity, driving gear is set on axle, electricity spiral shell cutter connects with axle, fastening assembly is mainly by travelling gear, the upper threshold force piece, the lower threshold force piece, the spiral shell cutter head, guide rail, slide block, screw clamp, return spring forms, upper threshold force piece and lower threshold force piece link with force-limit spring respectively, and be arranged at respectively in buckle and lower pinch plate, travelling gear coordinates connection with driving gear, the spiral shell cutter head coordinates with travelling gear and connects and be fixed on upper threshold force piece and lower threshold force piece, the guide rail lower end arranges screw clamp, return spring is set in guide rail, return spring top connects slide block, the other end of slide block connects with control loop.
Advantage of the present invention and beneficial effect are:
Use this device, can realize the function of fastening many screws of while on same work top, greatly improved efficiency, and can improve the uniformity of each screw firmness degree, thereby improve the assembly quality of workpiece.
The accompanying drawing explanation
Fig. 1 is the main cut-away view of a kind of screw fastening device of the present invention;
Fig. 2 be Fig. 1 partly cut open top view
In figure: 1-electricity spiral shell cutter, the upper buckle of 2-, 3-upper threshold force piece, the 4-slide block, the 5-return spring, the 6-guide rail, the 7-screw clamp, 8-spiral shell cutter head, 9-lower threshold force piece, the 10-lower pinch plate, the 11-travelling gear, the 12-driving gear, the 13-axle, the 14-control loop, the 15-force-limit spring,
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As Fig. 1, shown in Figure 2, a kind of screw fastening device, mainly by electric spiral shell cutter 1, upper buckle 2, axle 13, lower pinch plate 10, driving gear 12, control loop 14 and fastening assembly form, upper buckle 2, lower pinch plate 10 connects the formation cavity with control loop 14, axle 13 passes cavity and is arranged on cavity, driving gear 12 is set on axle 13, electricity spiral shell cutter 1 connects with axle 13, fastening assembly is mainly by travelling gear 11, upper threshold force piece 3, lower threshold force piece 9, spiral shell cutter head 8, guide rail 6, slide block 4, screw clamp 7, return spring 5 compositions such as grade, upper threshold force piece 3 and lower threshold force piece 9 link with force-limit spring 15 respectively, and be arranged at respectively in buckle 2 and lower pinch plate 10, travelling gear 11 coordinates connection with driving gear 12, spiral shell cutter head 8 coordinates with travelling gear 11 and connects and be fixed on upper threshold force piece 3 and lower threshold force piece 9, guide rail 6 lower ends arrange screw clamp 7, the interior return spring 5 that arranges of guide rail 6, return spring 5 tops connect slide block 4, the other end of slide block 4 connects with control loop 14.
For at same processing plane fastening many screws simultaneously, this device can configure the fastening assembly more than 2 on demand, fastening to realize with screwing, carrying out the while to 2.
Operating process of the present invention is mainly: after putting into screw in screw clamp 7, refill and be seated on workpiece to be assembled, adjust the dynamics of electric spiral shell cutter 1, the general right hand is held electric spiral shell cutter, left hand is pushed down this device, the right hand firmly by electric spiral shell cutter 1 to pressing down, return spring 5 is stressed, driving gear 12 band nutating gears 11 rotate spiral shell cutter head 8 by the workpiece screw-driving, in the situation that in the downward process of screw, screw clamp 7 can separate automatically stressed, simultaneously in this process, if certain screw-driving, but in the situation that other screws are not also tightened, the power of rotating because of travelling gear 11 is less than the power that driving gear 12 rotates, and the elastic force of upper threshold force piece 3 and lower threshold force piece 9 is less than the power of travelling gear 11, at this moment under the effect of power, upper threshold force piece 3 and lower threshold force piece 9 are drawn back, travelling gear 11 is separated with driving gear 12, spiral shell cutter head 8 will open direction from screw clamp 7 and move under the effect of upper threshold force piece 3 and lower threshold force piece 9, other screw is rotated further, certain screw-driving, when other are not also tightened, repeat said process, until screw is tightened fully.This device is exerted pressure after pressure cancels, and under the effect of return spring 5, returns to home position.
This device is particularly suitable for using in the electrical equipment assembling process, and in contactor, relay etc., working (machining) efficiency is high, steady quality.
