Abstract

CAPTURE DEVICE of the manipulator, comprising a housing, in the guides of which are mounted sliders carrying clamping jaws and rigidly connected to the toothed racks interacting with the toothed wheel located between the rails and mounted on the drive shaft, kinematically connected to the control handle, distinguished by that, in order to reduce changeover time to another size of clamped parts, it is equipped with a flywheel, a ratchet mechanism and a coupling, with a flywheel mounted on one end of the drive shaft and the other is a coupling with the possibility of connecting the drive shaft to the handle, while the toothed sector of the ratchet mechanism is mounted on the housing with the possibility of interaction with the ratchet pawl mounted on the shaft of the handle.

SP 1 The invention relates to hand-operated gripping devices for manipulators. The purpose of the invention is to reduce the time of changeover to another size of the clamped parts, as well as to improve the convenience of service due to the possibility of installing the control knob in a convenient position for work. FIG. 1 shows a gripping device, a general view; in fig. 2 the same, top view. The gripping device consists of body 1, clamping jaws 2 fixed on sliders 3 and crackers x 4. On sliders 3 there are fixed gear racks 5 interacting with gear wheel 6, inside which the drive shaft is rigidly fixed 7 "At the upper threaded end of the shaft it finds a nut -lap 8. Through the coupling halves 9 and THEN the control handle (the coupling half 10 is the hub of the control handle) is kinematically connected to the imported shaft 7. The spring 11 is intended to separate the coupling half 9 and 10 with the lamb turned 8 unscrewed. The flywheel is rigidly attached to the ala 7 (settings 12. The lid 13 with the ratchet gear sector, interoperates with the dog 14 mounted on the axis 15. The pusher 16 is held in its original position by the spring 17. The button 18. troughs the pusher 16 through the balls 19 The gripping device is attached to the head of the manipulator using the bracket 20. The gripping device operates as follows. The gripping jaws 2 of the gripping device are guided under the flange or shoulder of the gripping product. By turning the control knob clockwise, the clamping jaws 2 come together and clamp the product. When the control knob is turned clockwise (on the clamp), the ratchet pawl 14 slides along the teeth of the toothed sector (pressing the button 18 is not required). The product is transported. To dilute the clamping jaws 2, it is necessary to press button 18, turn the control knob counterclockwise (to unclamp). To change the gripping device to another size of the product being transported, it is necessary to unscrew the wing nut 8 by 3-4 turns, while the spring 11 will raise the coupling half 9 and the control knob turns out to be kinematically unassociated with the drive shaft 7. When you turn the handwheel, the setting 12 rotates the drive the shaft 7, and the gear wheel 6, as a result of which the toothed racks 5 move together with the sliders 3 in the guide bodies 1, therefore, the clamping jaws 2 associated with the sliders 3 and the crackers 4 also move. of the required distance between the clamping jaws 2 must tighten the wing nut 8. The direction of the toothed sector the teeth of the ratchet mechanism such that the article is provided a quick clamp (without pressing the button 18), but is prevented from unintentional dilution of the jaws 2 and a random vshadanie article. To dilute the clamping jaws 2, it is necessary to press the button 18, only after that the handle can be turned to unclamp. ipuz. l
