Abstract

The utility model belongs to an aircraft assembly tool design technology, and relates to improvement of a locating mechanism used for mounting a horizontal clamping board. The locating mechanism comprises a support (1), a screw pin (3) with a handle and a nut (4) with a handle, and is characterized in that a fork lug (6) is arranged, the lower surface of the fork lug (6) and the end of a horizontal arm of the support (1) are attached and are welded to a whole, a through hole is formed in the left side wall of an inserting groove of the fork lug (6), a straight groove (6a) is formed in the right side wall of the inserting groove of the fork lug (6), and an opening of the straight groove (6a) is formed in an upper groove opening of the inserting groove. According to the locating mechanism, a product can be taken down from a frame without dismounting the clamping board, the operating step is simplified, and work efficiency is improved.

Description

It is a kind of for the detent mechanism of horizontal clamp is installed

Technical field

The utility model belongs to aircraft rigger dress designing technique, relates to the improvement to the detent mechanism for horizontal clamp is installed.

Background technology

Current a kind of for the structure of detent mechanism that horizontal clamp is installed referring to Fig. 1, it is with handle spiral pin 3 and band handle nut 4 to form by bearing 1, riser 2.Bearing 1 is a rectangular plate of bending, has two pin-and-holes and two screw holes on the upright arm of bearing 1.The termination of the lower end of riser 2 and bearing 1 horizontal arm is welded as entirety.On riser 2, have a through hole, with handle spiral pin 3 through after the locating hole of horizontal clamp 5 from above-mentioned through hole pass and with 4 combinations of band handle nut, horizontal clamp 5 is pressed on riser 2.Its shortcoming is: before positioning product, staff is raised to clamp 5 after certain altitude, clamp 5 is fixed on riser 2 with handle location spiral pin 3 and handle nut 4; Because product exists stress in riveted joint process, product undercarriage difficulty, staff need to unclamp handle nut 4, unloads clamp 5 and is placed on bracket, could, by product undercarriage, cause complex operation, inefficiency.

Summary of the invention

The purpose of this utility model is: propose a kind of without unload clamp can by product undercarriage for the detent mechanism of horizontal clamp is installed, with the step that simplifies the operation, increase work efficiency.

The technical solution of the utility model is: a kind of for the detent mechanism of horizontal clamp is installed, comprise bearing 1, band handle spiral pin 3 and band handle nut 4, bearing 1 is a rectangular plate of bending, on the upright arm of bearing 1, there are two pin-and-holes and two screw holes, for being connected with jig frame, it is characterized in that: have a fork ear 6, the slot bottom of fork ear 6 is positioned at below, fit and are welded as entirety in the fork lower surface of ear 6 and the end of bearing 1 horizontal arm, on the left side wall of fork ear 6 slots, there is a through hole, on the right side wall of fork ear 6 slots, there is a straight trough 6a who is opened on notch on slot, on fork ear 6 left side walls, the position of through hole is corresponding with the position of straight trough 6a on right side wall, the width of straight trough 6a is greater than the maximum outside diameter with handle spiral pin 3, the lower limb of horizontal clamp 5 inserts in the slot of fork ear 6, pass through the through hole from fork ear 6 left side walls after the locating hole of horizontal clamp 5 with handle spiral pin 3 and with 4 combinations of band handle nut, horizontal clamp 5 is pressed on the left side wall of fork ear 6.

The utility model has the advantages that: can, by product undercarriage, simplify operating procedure without unloading clamp, improve operating efficiency.Evidence, adopts after the utility model, by the time shorten of product undercarriage more than 80%.

Brief description of the drawings

Fig. 1 is current a kind of for the structural representation of detent mechanism of horizontal clamp is installed.

Fig. 2 is structural representation of the present utility model.

Fig. 3 is the A-A cutaway view of Fig. 2.

Detailed description of the invention

Below the utility model is described in further details.Referring to Fig. 2, 3, it is a kind of for the detent mechanism of horizontal clamp is installed, comprise bearing 1, band handle spiral pin 3 and band handle nut 4, bearing 1 is a rectangular plate of bending, on the upright arm of bearing 1, there are two pin-and-holes and two screw holes, for being connected with jig frame, it is characterized in that: have a fork ear 6, the slot bottom of fork ear 6 is positioned at below, fit and are welded as entirety in the fork lower surface of ear 6 and the end of bearing 1 horizontal arm, on the left side wall of fork ear 6 slots, there is a through hole, on the right side wall of fork ear 6 slots, there is a straight trough 6a who is opened on notch on slot, on fork ear 6 left side walls, the position of through hole is corresponding with the position of straight trough 6a on right side wall, the width of straight trough 6a is greater than the maximum outside diameter with handle spiral pin 3, the lower limb of horizontal clamp 5 inserts in the slot of fork ear 6, pass through the through hole from fork ear 6 left side walls after the locating hole of horizontal clamp 5 with handle spiral pin 3 and with 4 combinations of band handle nut, horizontal clamp 5 is pressed on the left side wall of fork ear 6.

Using method of the present utility model is: under off working state, clamp 5 is positioned in the slot of fork ear 6; When work, clamp 6 need only be lifted, plug handle location spiral pin 3 and tighten handle nut 4, time saving and energy saving, when product undercarriage, only handle nut 4 need be unclamped, pull up handle location spiral pin 3, can be by clamp 6 and separation of products, then clamp 6 is placed in the slot of fork ear 6 and gets ready time and to use.
