Abstract

The utility model discloses a detaching device for spring coupling pin. One end of a bow shape frame is fixed with a nut which has a center line parallel with a bow arm. A screw stem passes through the nut, and the lower end of the bow shape frame is provided with an upswept hanger. During the process of use, the hanger is hooked on the edge of the back of an elastic coupling shaft to retain the lower part of the screw stem on the tip end of the pin so that the pin can be smoothly pulled out by the spanner or the upper end of the screw stem. The device is small in volume for using in narrow room, low in work intensity, high in work efficiency, easy to operate, safe and reliable, simple in structure and low in manufacture cost, of no damage to machine and people due to elimination of impact.

Description

Elastic coupling pin stripping attachment

Technical field

The utility model belongs to the instrument class, during specifically a kind of flexible rubber ring on changing shaft coupling, dismantles the specific purpose tool of its pin.

Background technology

During flexible rubber ring on changing elastic coupling, need its pin is extracted, usually the instrument of usefulness is hand hammer and drift, method is the microcephaly who drift is placed on pin, impact with hand hammer and to launch pin, its shortcoming is, because the residing position of shaft coupling is often very narrow and small, do not use strength when impacting, but also to take hammer, a hand steered drift, damage easily because of carelessness hand or other parts on the other hand, moreover will sell a hacking easily and cause and to take out, so both wasted parts, also existed potential safety hazard, particularly as the dismounting of harbour with the pin of large-scale elastic couplings mechanically such as large-scale door machine, labour intensity is big, inefficiency.

The utility model content

Impact many shortcomings of Chu such as the above-mentioned labour intensity that pin brings is big, dangerous, efficient is low for overcoming with hand hammer, the technical solution of the utility model is: at the transverse part of a segmental support one end, be fixed with its center line nut parallel with the bow arm of segmental support, screw rod is through in the nut, and the other end of segmental support has upward bent hook.

During use, hook is colluded at the shaft coupling back, the bottom of screw rod is withstood on the thin end of pin, turn the screw rod upper end, pin steadily can be ejected.Because described stripping attachment volume is little, can use at narrow space, labour intensity is little, and the effect height is easy to operate, does not impact, and does not damage parts and people, and is safe and reliable, simple in structure, low cost of manufacture.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a front view of the present utility model.

The specific embodiment

Among Fig. 1, lateral ends on segmental support top, be fixedly welded with nut 1, the center line of nut 1 is parallel with the bow arm 4 on the segmental support, and screw rod 2 is screwed in the nut 1, the upper end of screw rod 2, having what insert to twist for spanner can be two relative parallel planes, can be that four prisms cylinder, hexagonal prism or rib number become two prisms, can also be to be drilled with cross-drilled hole on the top of screw rod 2, inserts a cross bar 5 as twisting the removing with (seeing imaginary line place, figure top) of screw rod 2 in the hole in; The lower end of segmental support has the upward bent hook 3 (seeing imaginary line place, figure bottom) that catches on workpiece planarization.

Claims

1, a kind of elastic coupling pin stripping attachment is characterized in that: at the transverse part of a segmental support one end, be fixed with its center line and the parallel nut of bow arm, screw rod is through on the nut, and the lower end of segmental support has upward bent hook.

2, as the elastic coupling pin stripping attachment under the claim 1, it is characterized in that: the top at screw rod is porose, inserts a cross bar in the hole.

3, as the elastic coupling pin stripping attachment under the claim 1, it is characterized in that: have the rib number to become two prisms on the top of screw rod.
