Abstract
The utility model relates to a vacuum sucker preventing a screw from being inclined. The vacuum sucker preventing the screw from being inclined comprises a screwdriver bit, a sucker body, a screwdriver and the screw. The sucker body is installed at the front end of the screwdriver bit, the screwdriver penetrates through the screwdriver bit and the sucker body to make contact with the screw, the screw is located under the action of the vacuum suction force of the sucker body, the sucker body is columnar, three semi-cylindrical vacuum airflow channels are arranged on the side wall inside the sucker body, airflow is transmitted to the front end of the sucker body through the vacuum airflow channels, a step groove is formed in the front end of the sucker body, the screw is sucked on the sucker body, a nut of the screw is located in the step groove, the sucker body is provided with a nozzle, and a vacuum suction force pump provides the vacuum suction force to the sucker body. The vacuum sucker preventing the screw from being inclined solves the problem that in the prior art, a sucker is blocked, or the edge of a screw is easily blocked at a suction mouth of a four-corner quincuncial sucker and the screw needs to be set right before being locked. According to the vacuum sucker preventing the screw from being inclined, the screw is not inclined in the suction process, the screw can be locked without being set right, the alignment accuracy is high, labor intensity is relieved and production efficiency is improved.
Description
Technical field:
The utility model relates to lock screws appts field, relates in particular a kind of vacuum cups that prevents that screw is crooked.
Background technology:
Lock always there will be that to draw in screw process screw crooked during screw, after screw need to being set right, lock screw process again, not so there will be screw to locate inaccurate problem, its contraposition precision reduces, also the labour intensity that has increased operating personnel, has reduced production efficiency simultaneously.Pull of vacuum pump provides pull of vacuum to suction nozzle, by the vacuum pneumatic passage of establishing in suction nozzle, air-flow is sent to suction nozzle front end by passage, and draw screw, what suction nozzle in the past contacted screw foremost is smooth cylinder shape inner wall, when vacuum pneumatic is drawn screw, due to screwdriver bit and suction nozzle inwall gap very little of to prevent that screwdriver bit from rocking, and cap nut is also circular, in the time of in entering suction nozzle, there is certain probability to block suction nozzle, afterwards suction nozzle front end cylindrical was made into four jiaos of quincunx inboard wall of cylinder, vacuum pneumatic can freely be come in and gone out and draw screw from vacuum pneumatic passage like this, but this defect is: four jiaos of quincuncial suction inlets are symmetrical, screw edge is easily stuck in the suction inlet place in diagonal, before lock screw, need screw to set right.For need to designing a kind of suction nozzle, head it off overcomes the deficiencies in the prior art.
Utility model content:
The purpose of this utility model is for the deficiencies in the prior art part, a kind of vacuum cups that prevents that screw is crooked is provided, by this suction nozzle, can guarantee that in suction process, screw is not crooked, without locking again screw process after setting right, it increases contraposition precision greatly, reduce operating personnel's labour intensity simultaneously, improved production efficiency.
Technology solution of the present utility model is as follows:
Prevent the vacuum cups that screw is crooked, comprise screwdriver bit, suction nozzle, screwdriver and screw, described suction nozzle is arranged on the front end of screwdriver bit, and screwdriver contacts with screw with suction nozzle through screwdriver bit, and screw is located under the pull of vacuum effect of suction nozzle; Described suction nozzle is column, and suction nozzle internal side wall is provided with three half-cylindrical vacuum pneumatic passages, air-flow is sent to suction nozzle front end by vacuum pneumatic passage, and draws screw.
The front end of described suction nozzle is provided with a step trough, and when screw is adsorbed on suction nozzle, the nut of screw is partly positioned at step trough.
Described suction nozzle is provided with suction nozzle, and pull of vacuum pump provides pull of vacuum by suction nozzle to suction nozzle.
The beneficial effects of the utility model are:
The suction nozzle of three breach of the present utility model, the suction inlet of even number symmetric figure is made into the column suction nozzle of the asymmetric shape of odd number, owing to being asymmetric suction nozzle, even if therefore screw is crooked, also can automatically be adjusted into the position of aiming at suction nozzle because stablizing, asymmetric vacuum pneumatic passage, can fine control pull of vacuum, allows suction nozzle and the fine location of screw energy, can not cause screw off normal and screw to inhale and partially cause the problem of inefficiency, and improve greatly the stability of equipment.
Accompanying drawing explanation:
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation during without screw of the present utility model;
Fig. 3 is the structural representation of suction nozzle inside;
In Fig. 1～3: 1-screwdriver bit; 2-suction nozzle; 201-half-cylindrical vacuum pneumatic passage; 202-step trough; 3-screwdriver; 4-screw.
The specific embodiment:
Embodiment, is shown in accompanying drawing 1～3, a kind of vacuum cups that prevents that screw is crooked, comprise screwdriver bit 1, suction nozzle 2, screwdriver 3 and screw 4, described suction nozzle is arranged on the front end of screwdriver bit, and screwdriver contacts with screw with suction nozzle through screwdriver bit, and screw is located under the pull of vacuum effect of suction nozzle; Described suction nozzle is column, suction nozzle internal side wall is provided with three half-cylindrical vacuum pneumatic passages 201, air-flow is sent to suction nozzle front end by vacuum pneumatic passage, and draw screw, the column suction nozzle of the asymmetric shape of this odd number, even if screw is crooked, also can automatically be adjusted into the position of aiming at suction nozzle because stablizing, this asymmetric vacuum pneumatic passage, the fine control pull of vacuum of energy, allow suction nozzle and the screw can fine location, can not cause screw off normal and screw to inhale and partially cause the problem of inefficiency, and improve greatly the stability of equipment.The front end of described suction nozzle is provided with a step trough 202, and when screw is adsorbed on suction nozzle, the nut of screw is partly positioned at step trough.Described suction nozzle is provided with suction nozzle, and pull of vacuum pump provides pull of vacuum by suction nozzle to suction nozzle.
The utility model course of work, pull of vacuum pump provides pull of vacuum to suction nozzle, and the vacuum pneumatic passage by establishing in suction nozzle, is sent to suction nozzle front end by air-flow by vacuum pneumatic passage, and draw screw, then screwdriver work is attached to needed position by screw.
Claims (3)
1. a vacuum cups that prevents that screw is crooked, comprise screwdriver bit, suction nozzle, screwdriver and screw, it is characterized in that: described suction nozzle is arranged on the front end of screwdriver bit, screwdriver contacts with screw with suction nozzle through screwdriver bit, and screw is located under the pull of vacuum effect of suction nozzle; Described suction nozzle is column, and suction nozzle internal side wall is provided with three half-cylindrical vacuum pneumatic passages, air-flow is sent to suction nozzle front end by vacuum pneumatic passage, and draws screw.
