Description

Clamp rotating shaft pressing arm mechanism

Technical Field

The utility model relates to automobile parts production is with compressing tightly anchor clamps technical field, concretely relates to anchor clamps pivot pressure arm mechanism.

Background

Traditional anchor clamps pressure arm adopts single point or a plurality of pressure points, has following defect when producing:

1. the single pressing is adopted, one air cylinder can only press one position, so that the air cylinders are used too much, the cost is increased, the clamp layout is compact, and the maintenance is difficult;

2. the multiple spot compresses tightly, usually need through debugging many times, just can guarantee that each compresses tightly the point and reaches and compress tightly the effect, and appears slightly changing the condition in the part under, just can't realize compressing tightly completely.

Disclosure of Invention

The utility model provides a not enough to prior art, the utility model aims at providing an anchor clamps pivot pressure arm mechanism to solve the part plane degree and inconsistent, compress tightly the problem of inefficacy.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a clamp rotating shaft arm pressing mechanism which the key lies in: including the mount pad, be connected with actuating mechanism in the bottom of this mount pad the upper portion of mount pad is connected with the drive block through first pivot, actuating mechanism can drive first pivot is rotated the distal end of drive block forms the installation department the upper surface of installation department is connected with the one end of first pressure arm, the lower surface of installation department passes through the middle part pin joint of second pivot and second pressure arm the other end of first pressure arm is formed with the pressure head with the both ends of second pressure arm.

Furthermore, the driving block is of a U-shaped structure, two ends of the U-shaped structure are respectively located on two sides of the mounting seat and connected with two ends of the first rotating shaft, and the bottom of the U-shaped structure extends to form the mounting portion.

Furthermore, the central axis of the driving block is perpendicular to the central axis of the mounting seat.

Furthermore, the arrangement direction of the first pressure arm is vertical to that of the second pressure arm.

Furthermore, the first pressure arm and the pressure head and the second pressure arm and the pressure head are integrally formed.

The utility model discloses a show the effect and be:

the first pressure arm and the second pressure arm form multi-point type compression, a rotating shaft is additionally arranged in the middle of the second pressure arm, so that a lever principle is formed between pressure heads at two ends of the second pressure arm, when the flatness of a part is inconsistent, one pressure point of the part is firstly contacted with the surface of the part, the pressure arm can be compressed towards the other side through the reaction force until the two sides are completely compressed, the stress balance is achieved, a good compression and fixing effect is obtained, the precision and the manufacturing difficulty of the part can be effectively reduced, and the expected welding effect is achieved.

Detailed Description

The following provides a more detailed description of the embodiments and the operation of the present invention with reference to the accompanying drawings.

As shown in fig. 1-3, a clamp rotating shaft arm pressing mechanism comprises a mounting base 1, a driving mechanism 2 is connected to the bottom of the mounting base 1, a driving block 4 is connected to the upper portion of the mounting base 1 through a first rotating shaft 3, the driving mechanism 2 can drive the first rotating shaft 3 to rotate, an installation portion 5 is formed at the far end of the driving block 4, the upper surface of the installation portion 5 is connected with one end of a first pressing arm 6, the lower surface of the installation portion 5 is pivoted with the middle portion of a second pressing arm 8 through a second rotating shaft 7, and pressing heads 9 are formed at the other end of the first pressing arm 6 and two ends of the second pressing arm 8.

In this example, the driving block 4 is a U-shaped structure, two ends of the U-shaped structure are respectively located at two sides of the mounting base 1 and connected with two ends of the first rotating shaft 3, and the bottom of the U-shaped structure extends to form the mounting portion 5, so that two sides of the driving block 4 move in parallel under the driving of the driving mechanism.

In this example, the central axis of the driving block 4 is perpendicular to the central axis of the mounting base 1, so that the driving block has a better motion effect.

In this example, the first pressure arm 6 is perpendicular to the second pressure arm 8, so that the pressure arm mechanism of this embodiment has a better pressing effect.

In this embodiment, the first pressing arm 6 and the pressing head 9, and the second pressing arm 8 and the pressing head 9 are integrally formed, so that the pressing arm mechanism has better structural strength, and the service life of the pressing arm mechanism is ensured.

When the device is specifically implemented, multi-point type compression is formed by the first pressure arm and the second pressure arm, a rotating shaft is additionally arranged in the middle of the second pressure arm, so that lever principles are formed between pressure heads at two ends of the second pressure arm, when the flatness of a part is inconsistent, one pressure point of the second pressure arm is firstly contacted with the surface of the part, the pressure arm can be compressed towards the other side by the counter-acting force until the two sides are completely compressed, and the stress balance is achieved, so that a good compression and fixing effect is obtained, the part precision and the manufacturing difficulty can be effectively reduced, and the expected welding effect is achieved.

The technical scheme provided by the utility model is introduced in detail above. The principles and embodiments of the present invention have been explained herein using specific examples, and the above descriptions of the embodiments are only used to help understand the method and its core ideas of the present invention.
