Abstract
The utility model relates to a nut fastening device for a long connecting shaft and provides a single-nut tightening mechanism with higher specificity. The nut fastening device for the long connecting shaft comprises an electrical cabinet, a clamping and machining table, and a rack which is used for connecting the electrical cabinet with the clamping and machining table and providing support. A motor, a torque limiter and a drive gear in a dual-gear mechanism are installed in the electrical cabinet. A driven gear in the dual-gear mechanism is arranged at the upper part of the clamping and machining table. At the same time, a workpiece positioning device and a workpiece fixing device are additionally arranged on the clamping and machining table. The nut fastening device for the long connecting shaft has the advantages that not only can the demand of rapidly screwing a nut on the long connecting shaft be met and can the torque limitation be automatically completed, but also the labor intensity of workers can be greatly reduced because the automation level is higher.
Description
Technical field
The utility model relates to mechanical fastener, is specially being used on long connecting axle in a kind of mechanical connecting structure nut to be carried out fastening long connecting axle nut clamping device.
Background technology
At present, fastening nut comparatively efficiently mode need at least three steps just can finish:
(1) workpiece is simply fixing, manually nut is screwed in the screw rod button and guides;
(2) gas (electricity) trigger and sleeve cooperate, and fast nut are screwed in screw rod bottom (leaving surplus);
(3) with imitating good torque wrench, nut is pulled the setting moment of torsion.
The advantage of this mode is: highly versatile, and easy to operate, can satisfy the use needs of most of occasion; Yet also exist more weak point: as using for the short situation of screw rod, when before the screw rod longer connecting axle being arranged, between the requirement of stability, it is oversize that sleeve can't be done, and therefore, this assembling mode can only be used for the short workpiece of screw rod; In addition, because manually-operated is frequent, labour intensity is large, and efficient is low, and processing safety is poor, thereby is not suitable for the production in enormous quantities pattern of pipeline system.
The utility model content
In order to overcome nut under longer connecting axle impact, the problem that can't surely turn round fast, the utility model provides a kind of long connecting axle nut clamping device, this nut clamping device not only can effectively address this problem, can become simultaneously manual nut fastening be operating as semi-automatic, greatly reduce labor strength, improved simultaneously operational security.
The technical problem that the utility model solves realizes by the following technical solutions:
Long connecting axle nut clamping device, comprise regulator cubicle, clamping machine table and be used for connecting regulator cubicle and clamping machine table and the frame that provides support, wherein, the regulator cubicle bottom is provided with motor, be contained in a torque force limiting device on the output shaft of motor, and connected a pair of gear mechanism on top by torque force limiting device; In the described Double-gear mechanism, driving gear links to each other with torque force limiting device by connecting rod, driven gear then is positioned at clamping machine table top as the processing actuator of clamping machine table, simultaneously, for guaranteeing the location of processing work, also be respectively arranged with Working piece positioning device and Work fixing device in the upper and lower of clamping machine table.
In the utility model, described motor adopts the stepless time adjustment motor.
In the utility model, built-in torque sensor in the described torque force limiting device.
In the utility model, the mid portion of described clamping machine table also is provided with an auxiliary positioning bar, and the auxiliary positioning bar is fixed on the frame by bolt and support.
In the utility model, described Working piece positioning device is embedded in the driven gear, is used on the one hand positioning and clamping workpiece nut, also comes the fastening moment of torsion that provides for the workpiece nut by driven gear on the other hand.
In the utility model, electric control cabinet is by the rotating speed of control motor, and the output torque of regulating electric machine allows motor move under stable output torque, in this process, must notice that output torque should be greater than the required moment of torsion of clamp nut.
The utility model in use, output torque obtains required torque range through the effect of torque force limiting device.This moment of torsion is by the screw rod under the long connecting axle of Working piece positioning device drive nut screw-in, and when reaching required torque, torque force limiting device skids, and after sensor collects signal, stops by electric control cabinet control motor.Manually take off workpiece, finish this time assembling.
Beneficial effect: the utility model becomes manually as semi-automatic, has realized that the quick screw-in of nut under longer connecting axle turn round problem surely; Simultaneously can effectively reduce manually-operated, reduce labour intensity, improve efficiency of assembling.
Description of drawings
Fig. 1 is the laden schematic diagram of preferred embodiment of the present utility model.
Fig. 2 is the regulator cubicle part schematic diagram of preferred embodiment of the present utility model.
Fig. 3 is the clamping processing part side view of preferred embodiment of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to the long connecting axle of Fig. 1, Fig. 2, Fig. 3 embodiment with nut clamping device, in the present embodiment, to use this device and one long connecting axle is carried out nut be set with, its detailed process is as follows:
At first before use torque force limiting device 2 is needed check and correction, the torsion limits value is set in the required torque range of nut screwing clamping.After check and correction is finished, manually placing nut 9 and long connecting axle workpiece 10 are in the Working piece positioning device 5 on frame 7 tops, simultaneously, long connecting axle workpiece 10 is connected in the Work fixing device 6 of the tip of the axis insertion frame 7 bottoms, and utilize the auxiliary positioning bars 11 in the middle of the frame 7 to assist the correction location.
After guaranteeing long connecting axle workpiece 10 and nut 9 contrapositions, plugged, 8 pairs of motors of electric control cabinet 1 carry out speed governing, the output stable output moment of torsion of motor 1 (this moment of torsion is greater than required nut screwing clamping moment of torsion), output torque is through torque force limiting device 2 effects, pass to driving gear 3, driving gear 3 drives driven gear 4 and rotates, driven gear drives Working piece positioning device 5 and rotates, Working piece positioning device 5 drive nuts 9 screw in long connecting axle workpiece 10 screw portions, reach moment of torsion after, torque force limiting device 2 begins to skid, after sensor detects, stopped by electric control cabinet 8 control motors 1.After motor stops fully, manually take off workpiece, finish this assembling process.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
