Abstract
The utility model discloses a controllable torque machine head. The utility model is characterized in that a machine head lower body (1) is connected with a machine head upper body (5), the outside of the machine head upper body (5) is arranged with a bearing (3), a spring (6) and a washer (7) in turn, and after the outside of the machine head lower body (1) is arranged with the bearing (3), and the machine head lower body (1) is installed in an outer casing (4) to be connected as a whole body; a nut (9) is arranged at the upper end of the outer casing (4), a sealing ring (2) is arranged at the lower end of the outer casing (4), and an axle cover (10) is positioned at the end A of the machine head upper body (5). The utility model can enable the torque value of the nut to be tightened according to the torque requirements to reach the set scope, the production efficiency is high, and the cost is low.
Description
(1). technical field
The utility model is particularly related to a kind of instrument of clamp nut.
(2). background technology
Often need be in industrial production with pneumatic wrench with nut screwing clamping.Use the method for pneumatic wrench fastening nut at present, adopt the direct fastening nut of pneumatic wrench, therefore operation by rule of thumb often has moment to require for fastening nut, is difficult to screw-down torque is controlled in the scope of setting, influences assembly quality.
(3). goal of the invention
The purpose of this utility model provides a kind of controllable torque head.It can make the nut that is tightened of moment requirement, and its screw-down torque value reaches in the setting range, and the production efficiency height, and cost is low.
For reaching above-mentioned purpose, of the present utility model being characterised in that: the head lower body is connected with the head upper body, and outside, head upper body is bearing set spring and pad successively, and behind the bearing set of head lower body outside, installation fixedly combines as a whole in the enclosure; Nut is installed in the upper end of shell, and the lower end of shell is equipped with sealing ring, and the A end of head upper body is equipped with axle sleeve.
The utility model is because the moment of torsion of pneumatic wrench passes to the head upper body by axle sleeve, and the head upper body passes to the head lower body by stepped tooth, is used for fastening nut, therefore make and be tightened nut and have moment to require, its screw-down torque value reaches in the setting range, and the production efficiency height, and cost is low.
Below in conjunction with accompanying drawing the utility model is described further.
(4). description of drawings
Fig. 1 is a structure diagram of the present utility model.
(5). the specific embodiment
Referring to Fig. 1.With head lower body 1 and the engagement of head upper body 5 usefulness stepped tooths, trapezoidal toothed side angle is 45 °.5 outsides, head upper body are bearing set 3 springs 6 and pad 7 successively, behind the head lower body 1 outside bearing set 3, is installed in the shell 4, and shell 4 tops are provided with trip bolt 8.Bearing 3 can reduce the frictional force between head upper and lower body 5,1 and spring 7 and the shell 4, makes Torque Control more accurate, and sealing ring 2 can prevent that the lubricating oil in the head from leaking outside, and combines as a whole head lower body 1 and head upper body 5 with adjusting nut 9; With the thrust that adjusting nut 9 is adjusted between head lower body 1, the head upper body 5, adjust the back and lock with screw 8.The A end of head upper body 5 is equipped with axle sleeve 10, and the square hole of axle sleeve 10 endoporus and the A of head upper body 5 end lock with screw 8.
Scale and adjusting nut 9 are set on shell 4, and to regulate the size of moment, adjusting nut 9 upper surfaces are provided with graduation mark, the moment values that indication is regulated.When the needs fastening nut, by after the set point adjustment moment values, pneumatic wrench rifle head is injected the A end of overcoat 4, the B end of head lower body 1 injects in the sleeve of fastening nut, starts the switch knob of pneumatic wrench, and pneumatic wrench drives the sleeve rotating nut and does and tighten motion.When screw-down torque reaches setting value, stepped tooth produces and separates and skid between the head upper and lower body, and nut screwing clamping moment no longer increases, and guarantees that nut screwing clamping moment reaches the setting requirement.
The utility model is used for the utensil that electric drill and generation provide moment, can reach above-mentioned same effect.
Claims (7)
