Technical field
The utility model relates to a kind of device of electronic rigging screw, and the screw that specifically a kind of electronic rigging screw is used is decided locking apparatus.
Background technology
Traditional screw fastening method mainly is artificial method of tightening with screwdriver, and not only efficient is low, and labour intensity is big.The automatic fastening machine of the existing screw in market causes work to stop because of structure problem is stuck in screw in the clamping device easily.
The utility model content
The utility model technical problem to be solved provides the screw that a kind of electronic rigging screw uses and decides locking apparatus, and simple in structure, accurate positioning, efficient are high.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: the screw that a kind of electronic rigging screw is used is decided locking apparatus; Comprise housing, hollow shaft and overcoat; Be provided with the suitable screw placed channel of internal diameter and screw diameter in the hollow shaft; The upper end of hollow shaft is arranged in the hole clipping of housing bottom, and overcoat is enclosed within the hollow shaft outside, and is fixedly connected with housing; In housing, be provided with hollow shaft in the electric screw driver passage that is communicated with of screw placed channel; Electric screw driver passage and the coaxial setting of hollow shaft also are provided with screw operation passage in housing, screw operation passage is communicated with the screw placed channel; And has 20-30 ° angle with the electric screw driver passage; On the sidewall of hollow shaft, be provided with three manholes, on three manholes circumference that 120 ° are distributed in hollow shaft at interval, the position corresponding to manhole on the hollow shaft outer wall is provided with the excellent power glue shell fragment of a circle; In manhole, be provided with positioning ball; One side of positioning ball contacts with excellent power glue shell fragment, and the diameter of positioning ball is greater than the degree of depth of manhole, and manhole is positioned at the diameter of the inboard aperture, aperture of hollow shaft less than positioning ball.
The diameter of described positioning ball is 1.2-1.3 times of the manhole degree of depth.
When described excellent power glue shell fragment was in release position, it was 1/5-1/4 of screw placed channel diameter that positioning ball protrudes in the inboard height of hollow shaft.
The beneficial effect of the utility model is: simple structure, easy and simple to handle, advantages of small volume, clamping are reliable, can not produce screw upset and stuck phenomenon.Accurate positioning, efficiency of assembling height are realized the quick assembling of screw.

Fig. 2 is the set-up mode sketch map of positioning ball.
Mark among the figure: 1, housing, 2, hollow shaft, 3, overcoat, 4, screw, 5, the screw placed channel, 6, the electric screw driver passage, 7, screw operation passage, 8, manhole, 9, excellent power glue shell fragment, 10, positioning ball.
The specific embodiment
As shown in the figure; The screw that a kind of electronic rigging screw is used is decided locking apparatus; Comprise housing 1, hollow shaft 2 and overcoat 3, be provided with the internal diameter screw placed channel 5 suitable with screw 4 diameters in the hollow shaft 2, the size of the internal diameter of screw placed channel 5 makes screw 4 just can pass through to get final product.The upper end of hollow shaft 2 is arranged in the hole clipping of housing 1 bottom, and overcoat 3 is enclosed within hollow shaft 2 outsides, and is fixedly connected with housing 1; In housing 1, be provided with hollow shaft 2 in the electric screw driver passage 6 that is communicated with of screw placed channel 5; Electric screw driver passage 6 and hollow shaft 2 coaxial settings; In housing 1, also be provided with screw operation passage 7; Screw operation passage 7 is communicated with screw placed channel 5, and has 20-30 ° angle with electric screw driver passage 6, on the sidewall of hollow shaft 2, is provided with three manholes 8; Three manholes 8 are (be omissive representation among Fig. 1, a manhole only draws) on 120 ° of circumference that are distributed in hollow shaft 2 at interval.Position corresponding to manhole 8 on hollow shaft 2 outer walls is provided with the excellent power glue shell fragment 9 of a circle.Excellent power glue shell fragment 9 has the excellent power adhesive tape that is wrapped on hollow shaft 2 outer walls to constitute.In manhole 8, be provided with positioning ball 10, a side of positioning ball 10 contacts with excellent power glue shell fragment 9, and the diameter of positioning ball 10 is greater than the degree of depth of manhole 8, and manhole 8 is positioned at the diameter of the aperture, aperture of hollow shaft 2 inboards less than positioning ball 10.
The diameter of described positioning ball 10 is 1.2-1.3 times of manhole 8 degree of depth.When excellent power glue shell fragment 9 was in release position, it was 1/5-1/4 of screw placed channel 5 diameters that positioning ball 10 protrudes in hollow shaft 2 inboard height.Can be on the basis of the accuracy that improves the screw location through above-mentioned setting, reduce screw through the time resistance, improve the fluency and the assembling speed of assembling.
The course of work of clamp screws and rigging screw is divided 3 steps:
(1), through in the operation of the screw on the housing passage feeder, 3 positioning balls are realized the positioning clamping to screw to miniature screw by compressed air.
(2), the electric screwdriver head moves down the contact screw head through the electric screw driver passage; Under the effect of electric screwdriver head thrust; Screw promotes positioning ball, and positioning ball promotes excellent power glue shell fragment again, excellent power glue shell fragment generation strain; Positioning ball outwards moves, and falls the screw place on the part to be assembled through positioning ball until screw.
(3), the electric screwdriver head continues to move down, the contact screw head under the turning effort of electric screwdriver head, is accomplished rigging screw work.
