Abstract
The utility model discloses a position changer torsion adjusting device which comprises a screw rod (1), a counter weight (2) and a nut (3). The counter weight (2) is provided with an axial through hole and is mounted on the screw rod (1) in a sleeved mode through the axial through hole. The nut (3) is mounted on the screw rod and below the counter weight (2). The nut (3) is connected with the screw rod (1) through threads. The position changer torsion adjusting device has the advantages of being simple in structure, convenient to adjust, low in manufacturing cost, easy to assembly and stable in connection. Through the adjustment of the position of the counter weight on the screw rod, the adjustment of initial torque of a position changer is realized, and therefore the position changer can be suitable for workpieces with different weights, the application range of the position changer is extended, and the utilization rate of the position changer is improved.
Description
Technical field
The utility model relates to the welding auxiliary equipment, particularly positioner torsion adjusting device.
Background technology
Positioner is the special welding auxiliary equipment, is applicable to the welding displacement of revolution work, to obtain desirable Working position and speed of welding.Can with manipulator, the supporting use of welding machine, form automatic welding center, the workpiece displacement when also can be used for handwork.Work table rotation adopts frequency converter stepless speed regulation, adjusting speed accuracy height.
Positioner generally is made up of working platform swing mechanism and switching mechanism, makes the workpiece that is fixed on the workbench reach required welding by working platform overturning and revolution, and angle of assembling, work table rotation are variable-frequency stepless speed-regulating, can obtain satisfied speed of welding.But the control for the flip-flop movement of workbench just exists the jiggly problem of transmission, workpiece for Different Weight, be difficult to realize the constant speed smooth operation, in order to make upset reach constant speed, not influenced by workpiece weight, often just need higher drive unit and the transmission device of configuration precision, and this causes the cost of positioner to raise.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of cost positioner torsion adjusting device low, that can both steadily overturn for the workpiece of Different Weight.
The purpose of this utility model is achieved through the following technical solutions: positioner torsion adjusting device, it comprises screw mandrel, counterweight and nut, counterweight is provided with axially extending bore, counterweight is set on the screw mandrel by axially extending bore, nut is installed on the leading screw of counterweight below, nut and screw mandrel are by being threaded, and nut plays the position-limiting action that supports counterweight.
The side of being provided with, the top handle of described leading screw.
The top of described leading screw is provided with projection, is positioned on the screw mandrel of projection below to be set with thrust ball bearing.
Also be provided with deep groove ball bearing on the screw mandrel of described thrust ball bearing below.
The top of described counterweight is provided with circlip.
The utlity model has following advantage: the utility model is simple in structure, the convenient adjusting, and low cost of manufacture is easy to assembling, connects stable.By regulating the position of counterweight on screw mandrel, be that counterweight is apart from the vertical range of the motor shaft of positioner upset motor, realize the adjusting of positioner initial torque, when the workpiece weight on the positioner is big, can regulate counterweight, make it apart from the close together of motor shaft, thereby reduced the initial torque of positioner, the upset motor more does work to workpiece; When workpiece weight hour, regulating counterweight makes it far away apart from the motor shaft distance, thereby increased the initial torque of positioner, the more power output of counterweight consumption upset motor, thereby make the workpiece of positioner applicable to Different Weight, increase the scope of application of positioner, improved the utilization rate of positioner.

Among the figure, 1-screw mandrel, 2-counterweight, 3-nut, 4-side's handle, 5-projection, 6-thrust ball bearing, 7-deep groove ball bearing, 8-circlip for hole, 9-circlip.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, positioner torsion adjusting device, it comprises screw mandrel 1, counterweight 2 and nut 3, counterweight 2 is provided with axially extending bore, counterweight 2 is set on the screw mandrel 1 by axially extending bore, nut 3 is installed on the leading screw of counterweight 2 belows, and nut 3 and screw mandrel 1 are by being threaded, and nut 3 plays the position-limiting action that supports counterweight 2.
The side of being provided with, the top handle 4 of described leading screw, the convenient rotating threaded shaft of regulating.
The top of described leading screw is provided with projection 5, be positioned on the screw mandrel 1 of projection 5 belows and be set with thrust ball bearing 6, when screw mandrel 1 is arranged on the positioner, thrust ball bearing 6 is arranged in the default bearing block, support the weight of whole adjusting device by projection 5, and make screw mandrel 1 after adjusting device is installed, still can free rotate convenient the adjusting around the axle center.
Also be provided with deep groove ball bearing 7 on the screw mandrel 1 of thrust ball bearing 6 belows, also be provided with circlip for hole 8 on the screw mandrel 1 of deep groove ball bearing 7 belows.Arranging of deep groove ball bearing 7 can prevent rocking of screw mandrel 1, makes apparatus structure more stable.
The top of described counterweight 2 is provided with circlip 9, and circlip 9 is connected and fixed by bolt and counterweight 2, prevents that counterweight 2 adjusting transition from causing damage to last square structure.
By regulating screw mandrel 1 and nut 3, can regulate the position of counterweight 2 on leading screw, thereby the switching mechanism that can regulate positioner is realized the adjusting to the initial torque of positioner with respect to the moment of torsion of upset motor crankshaft, make its at the workpiece of Different Weight can both be stable displacement.
