Abstract

The utility model discloses a central ejector rod device, which aims at being simple in structure, reliable in work and convenient to unlock. The central ejector rod device comprises a fixing shaft arranged in a shaft base, a pressing shaft is inserted in the fixing shaft, a rotating shaft which is connected with a pressing jig through a bearing is arranged at the front end of the pressing shaft, and an inner hole matched with a connection shaft of the jig is arranged at the front end of the rotating shaft. The central ejector rod device is characterized in that a groove is arranged at the tail end of the fixing shaft, a swing arm is arranged in the groove, the rear end of the swing arm is fixed in the groove through a rear traverse pin, and the front end of the swing arm is connected with the rear end of a connection rod through a middle traverse pin. The front end of the connection rod is connected with the tail of the pressing shaft through a front traverse pin to form a crank sliding block mechanism, and a warping handle is connected with the front end of the swing arm. The central ejector rod device has the advantages that the jig is fast in positioning in the circumferential direction and the axial direction of a spindle, mounting and dismounting of the jig on an automatic winding machine are fast, convenient and flexible, and unlocking is especially convenient.

Description

The central term lever apparatus

Technical field

The utility model relates to a kind of frock on the automatic coil winding machine, more specifically to the clamping device of quick clamping fixture of the driving shaft of automatic coil winding machine and convenient for unlocking.

Background technology

When coil-winding, general earlier the skeleton of coil is installed on the tool (the fixedly frock of skeleton), tool is installed on the main shaft of automatic coil winding machine and by main shaft clamping back skeleton rotates the enforcement coil-winding with main shaft again.Therefore, the loading and unloading of tool on main shaft is very frequent action, and the quick loading and unloading of tool are directly connected to the efficient of coiling.And the handling speed of coil winding machine tool is slow usually, and automaticity is not high, and this will reduce the production efficiency of automatic coil winding machine greatly.

The utility model content

The purpose of the utility model provides a kind of simple in structure, reliable operation, the central term lever apparatus of convenient for unlocking.

In order to reach above-mentioned requirements, the technical scheme that the utility model adopted is: it includes fixed axis, and fixed axis is installed in the axle bed; Be inserted with compression axis in the fixed axis; The front end of compression axis is equipped with the rotating shaft that connects the tight tool of voltage supply through bearing, and the front end of rotating shaft is shaped on the endoporus that the connecting axle with tool matches, and it is characterized in that having groove at the tail end of fixed axis; In groove, be placed with swing arm; The rear end of swing arm through after lateral pin be fixed in the groove, the front end of swing arm and the rear end of connecting rod through in lateral pin link to each other, the front end of connecting rod links to each other with the afterbody of compression axis through preceding lateral pin; Form slider-crank mechanism, be connected with the handle that upwarps at the front end of swing arm.

Described central term lever apparatus is a plurality of being arranged side by side, and is fixed in the axle bed of same strip.

According to the central term lever apparatus that such scheme is made, it has the circumferential and axial location of tool on main shaft advantage soon and accurately.Make the loading and unloading of tool on the automatic coil winding machine very quick and flexible, especially release is very convenient.

Among the figure: 1, fixed axis; 2, axle bed; 3, compression axis; 4, bearing; 5, rotating shaft; 6, endoporus; 7, groove; 8, swing arm; 9, back lateral pin; 10, connecting rod; 11, middle lateral pin; 12, preceding lateral pin; 13, handle; 14, the axle bed of strip.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe.

Fig. 1, Fig. 2, Fig. 3 are the structural representation of central term lever apparatus, from figure, find out that it includes fixed axis 1; Fixed axis 1 is installed in the axle bed 2, is inserted with compression axis 3 in the fixed axis 1, and the front end of compression axis 3 is equipped with the rotating shaft 5 that connects the tight tool of voltage supply through bearing 4; The front end of rotating shaft 5 is shaped on the endoporus 6 that the connecting axle with tool matches; Tail end at fixed axis 1 has groove 7, in groove 7, is placed with swing arm 8, the rear end of swing arm 8 through after lateral pin 9 be fixed in the groove 7; The rear end of the front end of swing arm 8 and connecting rod 10 through in lateral pin 11 link to each other; The front end of connecting rod 10 links to each other with the afterbody of compression axis 3 through preceding lateral pin 12, forms slider-crank mechanism, is connected with the handle 13 that upwarps at the front end of swing arm 8.

Described central term lever apparatus has a plurality of being arranged side by side, and is fixed in the axle bed 14 of same strip, and is as shown in Figure 2.

The method of using is: connecting axle that earlier will use tool supporting with it is inserted in the corresponding endoporus 6, and behind assembling fixture, as long as push handle 13, connecting rod 10 promotes compression axises 3 and moves forward like Fig. 4, shown in Figure 5, thereby rotating shaft 5 moves with tool.The method of method and installation noted earlier of taking off tool is reverse, and pull-up handle 13, compression axis 3 are retreated indentation such as Fig. 2, shown in Figure 3.

Claims
