Description

TECHNICAL FIELD

[0001] The utility model relates to the field of tooling fixture especially relates to automatic positioning fixture. BACKGROUND

[0002] The horn is a kind of modern electroacoustic element, and the function is to convert electrical signal into sound, also called loudspeaker. It is basically divided into two kinds of inner magnetic type and outer magnetic type, and the outer magnetic type is mostly used with ferrite;Inner magnetic type magnetic circuit uses aluminum, nickel, diamond alloy magnet, and a few also adopt ferrite.

[0003] For outer magnetic electric loudspeaker, the outer magnetic horn can be seen as a circle of black magnet between T iron and hua si, since the magnet and T iron need to be glued and fixed, the traditional gluing method is to place T iron and magnet together and glue by artificial, which makes the efficiency low and also can appear gluing defects, affect the overall product quality, some are also glued with fixture, but the fixture can only be glued for subsequent gluing of certain specification, and the applicability is low, so the automatic positioning fixture is proposed. INVENTION CONTENTS

[0004] The utility model aims at providing a technical scheme that can solve the above problems to overcome the above-mentioned shortcomings.

[0005] Automatic positioning fixture, including fixed base, the fixed base top end is vertically provided with connecting column, and the connecting column top end is elastically sleeved with lock ring, and the gap is formed between the lock ring and the connecting column, the top of the connecting column is formed with a storage groove, and the groove wall inside the storage groove is evenly distributed and formed with a plurality of through holes, and a plurality of through holes are placed with a plurality of through holes and the ball can move in the through hole, the lock ring is formed with a convex strip, and the convex strip is formed around the top of the lock ring inside, and the convex strip and the through hole are parallel to each other and the convex strip moves up and down with the lock ring on one side of the through hole, so that the lock ring moves up and down on the top of the connecting column, and the ball in the through hole is pushed by the convex strip and the ball is protruded from the through hole.

[0006] Preferably, the lock ring and the connecting column are provided with a spring, and the spring is vertically sleeved on the outside of the top of the connecting column, and the lock ring is sleeved on the outside of the spring, and the upper and lower ends of the spring are in contact with the top inside of the lock ring and the bottom of the outside of the connecting column respectively.

[0007] Preferably, the lock ring and the connecting column are further provided with a snap spring, and the snap spring is transversely inserted into the top of the connecting column outside, and the snap spring is transversely arranged on the top of the lock ring.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: When the T-iron placement rack needs to be inserted into the storage slot at the top of the connecting column, the operator pulls the locking ring downwards, causing the convex strip to move downwards from the side of several through holes, thereby resetting the protruding ball. At this time, the operator inserts the T-iron placement rack into the storage slot and releases the locking ring, causing the locking ring and the convex strip to elastically reset, thereby causing the convex strip to move back to the side of several through holes and push the ball again, so that the protruding ball closes into the storage slot and clamps and limits the T-iron placement rack placed inside the storage slot. The cooperation between the locking ring and the ball allows different types of T-iron placement racks to be limited and fixed when inserted into the connecting column, thus ensuring that different types of T-irons and magnets do not need to be frequently replaced with corresponding clamps when they are glued together.

[0009] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 In this embodiment of the utility model, the automated positioning fixture includes a fixed base 1. A connecting post 2 is vertically arranged at the top of the fixed base 1, and a locking ring 3 is elastically fitted at the top of the connecting post 2, forming a gap between the locking ring 3 and the connecting post 2. A storage groove 4 is formed at the top of the connecting post 2, and a plurality of through holes 5 are formed around the inner wall of the storage groove 4. A ball bearing 6 is placed inside each of the through holes 5, and the ball bearing 6 can move inside the through holes 5. A protrusion 8 is formed on the locking ring 3, and the protrusion 8 is formed around the top of the locking ring 3. The protrusion 8 is parallel to the through holes 5, and the protrusion 8 moves up and down with the locking ring 3 on one side of the through holes 5. Thus, when the locking ring 3 moves up and down at the top of the connecting post 2, the protrusion 8 pushes the ball bearing 6 inside the plurality of through holes 5, causing the ball bearing 6 to move out of the plurality of through holes 5. The through-hole 5 protrudes inside. When the T-iron placement rack needs to be inserted into the storage slot 4 at the top of the connecting column 2, the operator pulls the locking ring 3 downward, causing the protruding strip 8 to move downward from the side of several through-holes 5, thereby resetting the protruding ball 6. At this time, the operator inserts the T-iron placement rack into the storage slot 4 and releases the locking ring 3, causing the locking ring 3 and the protruding strip 8 to elastically reset. This causes the protruding strip 8 to move back to the side of several through-holes 5 and push the ball 6 again, so that the protruding ball 6 closes into the storage slot 4 and clamps and limits the T-iron placement rack placed in the storage slot 4. The cooperation between the locking ring 3 and the ball 6 allows different types of T-iron placement racks to be limited and fixed when inserted into the connecting column 2, thus ensuring that different types of T-irons and magnets do not need to be frequently replaced with corresponding clamps when they are glued together.

[0018] A spring 7 is provided between the locking ring 3 and the connecting post 2. The spring 7 is vertically fitted outside the top of the connecting post 2. The locking ring 3 is fitted outside the spring 7, and the upper and lower ends of the spring 7 contact the top of the inside of the locking ring 3 and the bottom of the outer side of the connecting post 2, respectively. Thus, the locking ring 3 can move elastically outside the top of the connecting post 2 through the spring 7. When the locking ring 3 moves elastically outside the connecting post 2 through the spring 7, it drives the protrusion 8 to push the ball 6, so that the ball 6 can move inside several through holes 5.

[0019] A retaining spring 9 is also provided between the locking ring 3 and the connecting post 2. The retaining spring 9 is horizontally inserted into the top of the connecting post 2 and is horizontally supported at the top of the locking ring 3. This allows the locking ring 3 to be limited by the retaining spring 9 when it elastically moves at the top of the connecting post 2, thereby preventing the locking ring 3 from flying off the connecting post 2 during elastic movement.

[0020] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
