Description
Technical field
The utility model relates to the interim alignment pin of a kind of lever, for the interim alignment pin of locating between workpiece and workpiece and between workpiece and frock temporarily.
Background technology
At present a kind of interim alignment pin of extensive use in the manufacture and assembling process of aircraft.The interim alignment pin of this tradition have employed the larger spring of a coefficient of elasticity, cannot operate by direct hand, in use needs location pin pliers auxiliary operation.Because alignment pin caliper is long-pending larger, use often limited at some small spaces.
Summary of the invention
The technical problems to be solved in the utility model is to provide the interim alignment pin of a kind of lever, the interim alignment pin of this lever adopts the spring that two coefficient of elasticity are different, bear pressing respectively to block workpiece and apply these two kinds of functions of chucking power to workpiece, like this can be more laborsaving in operation, external tool need not be used to realize, without the need to large assembly space, improve accessibility, and simple to operate, use convenient.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: the interim alignment pin of a kind of lever, limit spring is provided with in the bottom of sleeve, take a seat limited post in limit spring upper end, clamp springs is provided with in the ring cavity formed between the excircle of limited post and the inner periphery of sleeve, be provided with spacing ring in clamp springs upper end, spacing ring is connected with limited post top; Stretch into two symmetrically arranged spring bows at spacing Ring current distribution, the bottom of spring bow passes from sleeve bottom; The outer surface of each spring bow lower end is provided with semicircular platform body structure, is provided with isolation tongue, is provided with base ring at the intracavity bottom of sleeve between the medial surface of two spring bows, and the upper end of isolation tongue is L-type structure, and spacing on base ring by limit spring; Be provided with thimble in the upper end of spacing ring, the upper end of thimble is stretched out from the upper end of sleeve.
The outer wall of described sleeve is provided with two symmetrical vertical strip holes, and be provided with pressure ring at the excircle of limited post, pressure ring upper surface contacts with clamp springs bottom surface; Be provided with fixed axis in the excircle lower end of sleeve, the bottom of spanner is two symmetrical claws, and the lower end of claw is flexibly connected with fixed axis, and claw upper end is flexibly connected with one end of pole, and the pressure ring piecemeal activity that the other end and the strip hole of pole expose is connected.
The coefficient of elasticity of described limit spring is less than the coefficient of elasticity of clamp springs.
The interim alignment pin of this lever adopts double-spring structure, can make to be inserted in the hole of location bottom spring bow by the limit spring of bottom, then to be held out against spring bow by the clamp springs of top and prevents alignment pin from coming off.
Preferably, promote pressure ring moves by the spanner of outside, thus clamp springs is compressed further, thus ensure that spring bow lower end and locating hole hold out against further.
Adopt the limit spring that coefficient of elasticity is less, during to ensure to press down spring bow, less power can be used to complete location; Adopt the clamp springs that coefficient of elasticity is larger, to ensure alignment pin Clamp blocks.
Spanner is set outside sleeve, pressure ring can be driven to rise by bar linkage structure, thus compression clamp springs, ensure the chucking power of spring bow.

Detailed description of the invention
As depicted in figs. 1 and 2, the interim alignment pin of a kind of lever, limit spring 13 is provided with in the bottom of sleeve 3, take a seat limited post 11 in limit spring 13 upper end, clamp springs 12 is provided with in the ring cavity formed between the excircle of limited post 11 and the inner periphery of sleeve 3, be provided with spacing ring 8 in clamp springs 12 upper end, spacing ring 8 is connected with limited post 11 top; Stretch into two symmetrically arranged spring bows 9 at the center of spacing ring 8, the bottom of spring bow 9 passes bottom sleeve 3; The outer surface of each spring bow 9 lower end is provided with semicircular platform body structure, isolation tongue 7 is provided with between the medial surface of two spring bows 9, be provided with base ring 14 at the intracavity bottom of sleeve 3, the upper end of isolation tongue 7 is L-type structure, and spacing on base ring 14 by limit spring 13; Be provided with thimble 2 in the upper end of spacing ring 8, the upper end of thimble 2 is stretched out from the upper end of sleeve 3.
The outer wall of described sleeve 3 is provided with two symmetrical vertical strip holes, and be provided with pressure ring 4 at the excircle of limited post 11, pressure ring upper surface contacts with clamp springs 12 bottom surface; Fixed axis is provided with in the excircle lower end of sleeve 3, the bottom of spanner 1 is two symmetrical claws, the lower end of claw is flexibly connected with fixed axis, and claw upper end is flexibly connected with one end of pole 5, and pressure ring 4 piecemeal activity that the other end and the strip hole of pole 5 expose is connected.
The coefficient of elasticity of described limit spring 13 is less than the coefficient of elasticity of clamp springs.
The use of the interim alignment pin of lever of the application is mainly divided into following two steps:
Step one: as shown in Figure 3, with hand pressing thimble 2, stretches out after outside isolation tongue 7 until spring bow 9, is inserted in locating hole.Its principle: when thimble 2 is to when pressing down, drive two spring bows 9 descending, now limit spring 13 is compressed, and the coefficient of elasticity of limit spring 13 is smaller, need not apply very large power and just can complete in compression travel; When two spring bows 9 be compressed to stretch out isolation tongue 7 after, spring bow 9 head inwardly contacts, and now can pass locating hole;
Step 2: as shown in Figure 4, unclamps finger, and the head of spring bow 9 is stuck on the locating hole of bottom.Its principle: after unclamping finger, because the effect of limit spring 13, drives spring bow 9 up.When the head of spring bow 9 arrives two rear flank isolating tongue 7 again, the semicircle platform body structure of spring bow lower end outer surface will be stuck in outside part, and then realize simple clamping.
Step 3: as shown in Figure 5, upwards lifts spanner 1 with finger, makes spanner be adjacent to the sleeve 3 of alignment pin, realizes clamping.Its principle: while upwards lifting spanner 1, the pressure ring 4 be connected by pole 5 is moved upward, and clamp springs 12 is compressed, clamps two workpiece.In addition, because the design feature of spanner 1, pole 5 exceedes the peak of spring clamp, and the trend making the clamping force of spring simultaneously can limit pole 5 to move to the left, makes structure latches.
The process of taking off alignment pin is contrary with installation process.
