Abstract

The utility model discloses an automatic holding device, and aims to provide an automatic holding device which has the advantages of simple structure and reliable operation, and is able to realize automatic control over the operation of holding coils. The device comprises a holder and a moveable bar, wherein, the middle part of the moveable bar is fixed on the holder by using a pin shaft, a fixed finger is mounted at the front end of the holder, a moveable finger is mounted at the front end of the moveable bar, the moveable finger and the fixed finger correspond to each other, a slide block is arranged between the rear end of the moveable bar and the holder, an oblique-wedge surface is formed at one end of the slide block, the rear end of the moveable bar is placed on the oblique-wedge surface; the process of the moveable finger moving towards or away from the fixed finger is realized depending on the slide block moving to drive the hooked cutter bar to rotate around the pin shaft; and the movement of the slide block is realized by the expansion and the contraction of a piston rod connected with the slide block. The utility model can control not only the process of the moveable finger move towards or away from the fixed finger but also the position of the whole automatic holding device when in motion, thereby enabling an automatic coil winding machine to operate at a higher automation level.

Description

Automatic clamping device

Technical field

The utility model relates to clamping device, relates to the automatic clamping device to winding the line on the automatic coil winding machine in particular.

Background technology

Many automatic coil winding machines are just realized automation in the operating mode of coiling, when the coiling beginning, one end of coiling need be fixed, the other end is reeled, cut off after after coiling finishes, needing again coiling fixed, therefore the fixing and clamping to coiling is action frequent and important in the coil winding machine, but this also needs to rely on manual operations to many coil winding machines, and this will reduce the production efficiency of automatic coil winding machine greatly.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, reliable operation, can be to the automatic clamping device controlled automatically of clamping work of coiling.

In order to reach above-mentioned requirements, the technical scheme that is adopted is: it comprises holding frame, motion bar, the middle part of motion bar is fixed on the holding frame with bearing pin, the front end of holding frame is equipped with fixed finger, the front end of motion bar is equipped with movable finger, movable finger is relative with fixed finger, between the rear end of motion bar and holding frame, be provided with slide block, one end of slide block is shaped on the face of tiltedly carving, the rear end of motion bar rests tiltedly carves on the face, movable finger drives motion bar with respect to the folding of fixed finger by moving of slide block and rotates around bearing pin and realize, is connected with piston rod on the slide block, and the coupled piston rod that moves through of slide block stretches and realizes.

Be connected with fixed block on the described holding frame, fixed block is connected with other motion control devices, is used for the motion control to whole automatic clamping device.

The automatic clamping device of making according to such scheme drives the motion of slide block and motion bar by the control piston bar, makes that movable finger is relative with fixed finger to be closed up or open, and realization is to the clamping of object and loosen.Simultaneously, holding frame can be realized the control to whole automatic clamping device movement position again with after other motion control devices are connected, and makes automatic coil winding machine have higher automaticity.

Wherein: 1, holding frame; 2, motion bar; 3, bearing pin; 4, fixed finger; 5, movable finger; 6, slide block; 7, tiltedly carve face; 8, roller; 9, extension spring; 10, compression spring; 11, piston rod; 12, fixed block; 13, oil cylinder or cylinder; 14, tracheae or oil pipe.

Embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

Fig. 1, find out among Fig. 2, automatic clamping device, it comprises holding frame 1, motion bar 2, the middle part of motion bar 2 is fixed on the holding frame 1 with bearing pin 3, the front end of holding frame 1 is equipped with fixed finger 4, the front end of motion bar 2 is equipped with movable finger 5, activity finger 5 is relative with fixed finger 4, between the rear end of motion bar 2 and holding frame 1, be provided with slide block 6, one end of slide block 6 is shaped on and tiltedly carves face 7, the rear end of motion bar 2 is equipped with roller 8, the rear end of motion bar 2 by roller 8 with tiltedly carve face 7 and contact, the rear end of motion bar 2 rests by roller 8 and tiltedly carves on the face 7, and between the rear end of motion bar 2 and holding frame 1 extension spring 9 is installed, and compression spring 10 is installed in slide block 6 rear ends in addition makes and tiltedly carve face 7 and keep in touch with roller 8.Movable finger 5 drives motion bar 2 with respect to the foldings of fixed finger 4 by moving of slide block 6 and realizes that around bearing pin 3 rotations be connected with piston rod 11 on the slide block 6, piston rod 11 is driven by hydraulic pressure or air pressure.The coupled piston rod 11 that moves through of slide block 6 stretches and realizes.Be connected with fixed block 12 on holding frame 1, fixed block 12 is connected with other motion control devices, is used for the control to automatic clamping device movement position.

When the movable finger of needs 5 relative fixed finger 4 opens, pressurization in the tracheae of cylinder or oil cylinder 13 or oil pipe 14, make piston rod 11 drive slide block 6 and move down together, overcome the tension force of compression spring 10, the activity finger of ining succession in the upper end of motion bar 25 opens as shown in Figure 2 together.When cylinder or oil cylinder 13 releases, compression spring 10 drives motion bar 2 motions with slide block 6 jack-up, and the closure of realization activity finger 5 and fixed finger 4 clamps object as shown in Figure 3.
