Description

A kind of drop test facility delivery device
The present invention is a kind of drop test facility delivery device, belongs to the technical field of structures of product.
Background technology
In the development process of aircraft, need aircraft components to carry out drop-test, the delivery device of domestic existing drop test facility is mainly electromagnetism delivery device.It mainly relies on electromagnet and tension spring to control the closure of clamp.When electromagnet no power, jaw is closed, and when electromagnet is switched on, jaw opens.These device parts are more, and electromagnet load-bearing capacity is limited, the most about 35T at present, and sometimes there is the wild effect of not opening in jaw folding; Secondly electromagnetic interference (EMI) has a certain impact to DATA REASONING.
Summary of the invention
The deficiency that the present invention exists for above-mentioned existing apparatus just and design a kind of drop test facility delivery device is provided, its objective is and increase by the input weight of drop-test part, thrown testpieces and can be reached 110T, the reliability that assurance is thrown in by testing equipment, solve electromagnetism delivery device electromagnetic interference (EMI) in the past simultaneously and, on the impact of DATA REASONING and input instability, thrown in favorable repeatability.
The object of the invention is to be achieved through the following technical solutions:
This kind of drop test facility delivery device, it is characterized in that: this device comprises two tong arms (1), by large bearing pin (3), be arranged on housing (4), be symmetrically arranged, tong arm (1) can rotate around large bearing pin (3), realize the opening and closing of tong arm (1) jaw, the top of each tong arm (1) is connected with one end of a connecting rod (7) by a small clevis pin with head (5), the installation site of the small clevis pin with head (5) on tong arm (1) is in the top of large bearing pin (3), the other end of two connecting rods (7) interconnects by a small clevis pin with head (5) again, the upper suit of this small clevis pin with head (5) guide pole (6), the upper processing of guide pole (6) vertical gathering sill (12), in gathering sill (12), pass a guide rod (2), guide rod (2) is fixedly mounted on housing (4), the length of gathering sill (12) should be greater than jaw and be closed to and open walked stroke,
The upper inner face of two tong arms (1) is an inclined-plane (13), this inclined-plane (13) is less than 5 degree with the angle θ of vertical direction, between the upper inner face of two tong arms (1), embed a voussoir (8), voussoir (8) is placed on the mounting groove (15) on housing (4) top, making the bottom of voussoir (8) over against the plane of symmetry of two tong arms (1), matches with the inclined-plane (13) of tong arm (1) upper inner face in the two sides (14) of voussoir (8).
The both sides of voussoir (8) bottom are processed with chamfering (16), are conducive to the insertion of voussoir (8) and extract, and avoid stuck phenomenon.。
Feature of the present invention is to adopt mechanical structure, and tong arm (1) rotates around large bearing pin (3), realizes the opening and closing of jaw.Tong arm (1) is connected with connecting rod (7), guide pole (6) by small clevis pin with head (5); Guide rod (7) can slide in the gathering sill (12) of guide pole (6), and the interoperation between them is symmetrical while having guaranteed tong arm (1) opening and closing, guarantees the centering of drop-test part.
The advantage of apparatus of the present invention is:
1. adopt hydraulic actuator to pull voussoir, control the opening and closing of delivery device jaw; During without testpieces, jaw is open configuration with deadweight, and convenience is connected with tested testpieces; During installation test part, testpieces jack-up guide pole, jaw is closed, then inserts voussoir.During input, draw voussoir, rely on and by the deadweight of drop-test part, jaw is opened, drop-test part, launch process is simple, reliable.
2. reduce electromagnetism delivery device electromagnetic interference (EMI) in the past, measurement data is more accurate;
3. solved electromagnetic hydraulic pressure delivery device in the past and be subject to electromagnetic lock to use the restriction of tonnage scope, tested equipment tonnage to be increased to 110T;
4. more easy to assembly with original input structure, simple, favorable repeatability.
Accompanying drawing explanation

Fig. 2 is the one-piece construction schematic diagram of apparatus of the present invention jaw open configuration
Fig. 3 is the three-dimensional view of apparatus of the present invention wedge structure
Embodiment
Below with reference to drawings and Examples, technical solution of the present invention is further described:
Shown in accompanying drawing 1~2, this kind of drop test facility delivery device, it is characterized in that: this device comprises two tong arms 1, by large bearing pin 3, be arranged on housing 4, be symmetrically arranged, tong arm 1 can rotate around large bearing pin 3, realize the opening and closing of tong arm 1 jaw, the top of each tong arm 1 is connected with one end of a connecting rod 7 by a small clevis pin with head 5, the installation site of the small clevis pin with head 5 on tong arm 1 is above large bearing pin 3, the other end of two connecting rods 7 interconnects by a small clevis pin with head 5 again, on this small clevis pin with head 5, be set with a guide pole 6, on guide pole 6, process a vertical gathering sill 12, in gathering sill 12, pass a guide rod 2, guide rod 2 is fixedly mounted on housing 4, the length of gathering sill 12 should be greater than jaw and be closed to and open walked stroke,
