Description

Technical Field

[0001] The utility model relates to the technical field of industrial fixtures, in particular to a fixture for machining aviation parts. Background Art

[0002] The aviation industry is the most advanced industry in the industry. Every part in the aviation industry needs to work reliably and permanently under high temperature, high pressure and high stress. These aviation parts often need to be fixed by fixtures. The existing fixtures will inevitably damage the surface of the aviation parts, and the parts cannot be rotated, making it difficult to process the reverse side of the parts.

[0003] Later, some fixtures that can flip parts appeared, but no matter whether it is a two-axis fixture or a four-axis fixture, each axis is independent. In this setting, different axes need to be synchronized during flipping to ensure flipping. If the drive device of one of the axes fails, the axes will be out of sync during flipping, the flipping function will fail, and the failure rate is high.

[0004] Therefore, we propose a fixture for machining aviation parts. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a fixture for machining aviation parts.

[0006] In order to achieve the above-mentioned invention object, the technical solution adopted by the utility model is:

[0007] A clamp for machining aviation parts comprises a clamping mechanism, including a left clamping arm, a right clamping arm and a clamping arm rod, the left clamping arm and the right clamping arm are slidably arranged on the clamping arm rod, and the left clamping arm and the right clamping arm are clamped and released by the clamping mechanism; a flipping mechanism is fixedly connected to the clamping arm rod, and the flipping mechanism is used to flip the clamping mechanism; and a fixed seat, on which the flipping mechanism is fixedly arranged.

[0008] By setting up a flipping mechanism to flip the clamping mechanism as a whole, the reverse side of the part can be processed, which is very convenient. Compared with a multi-axis fixture in which each axis is driven by a driving mechanism, the problem of asynchronous flipping caused by failure of any of the multiple axes can be avoided by directly flipping the clamping mechanism as a whole. The structure is simple, the number of flipping components is reduced, and the failure rate is reduced.

[0009] It is further defined that the clamping mechanism includes a clamping motor and a clamping screw, the clamping arm rod is hollow, the clamping screw is inserted into the clamping arm rod along the length direction of the clamping arm rod, the clamping motor is fixedly arranged on one end face of the clamping arm rod, one end of the clamping screw is fixedly connected to the output shaft of the clamping motor, and the inner side face of the clamping arm rod is provided with a clamping strip hole for the left clamping arm and the right clamping arm to pass through along the length direction of the clamping arm rod, the left clamping arm and the right clamping arm both pass through the clamping strip hole and are threadedly connected to the clamping screw at the tail end, and the internal threads on the left clamping arm and the right clamping arm are arranged in opposite directions to The two can move relative to or away from each other at the same time; the clamping motor drives the clamping screw to rotate, and the clamping screw rotates. The tail threads of the left clamping arm and the right clamping arm are connected to the clamping screw, and the clamping strip holes can limit the left clamping arm and the right clamping arm so that the left clamping arm and the right clamping arm will not rotate with the clamping screw. At this time, the left clamping arm and the right clamping arm will move on the clamping screw. Since the threads of the left clamping arm and the right clamping arm are in opposite directions, the left clamping arm and the right clamping arm can move relative to each other to realize the clamping function, and move away from each other to realize the loosening function.

[0010] It is further defined that the fixing seat includes a horizontal bottom plate and a column vertically arranged on the horizontal bottom plate.

[0011] It is further defined that the flipping mechanism includes a flipping motor and a motor seat, the motor seat is an L-shaped plate, the vertical plate section of the motor seat is fixedly arranged on the side wall of the column, the flipping motor is fixedly arranged on the horizontal plate section of the motor seat, and the output shaft of the flipping motor is fixedly connected to the midpoint of the outer side surface of the clamping arm rod; the clamping mechanism is flipped by the flipping motor, the structure is simple, and the operation is convenient. Setting the motor seat as an L-shaped plate can increase the connection area between the motor seat and the column and improve the stability of the connection.

[0012] It is further defined that the inner sides of the left clamp arm and the right clamp arm are provided with anti-skid pads; providing anti-skid pads on the inner sides of the left clamp arm and the right clamp arm can increase the friction between the parts and improve the stability of clamping.

[0013] The beneficial effects of the utility model are as follows: the entire clamping mechanism is flipped by a flip motor, thereby achieving the effect of flipping parts. Compared with a multi-axis individually driven synchronous flipping structure, it is simpler, more stable and has a lower failure rate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The specific implementation methods of the utility model are described below to facilitate technical personnel in this technical field to understand the utility model, but it should be clear that the utility model is not limited to the scope of the specific implementation methods. For ordinary technical personnel in this technical field, as long as various changes are within the spirit and scope of the utility model defined and determined by the attached claims, these changes are obvious, and all utility model creations using the concept of the utility model are protected.

[0019] Example:

[0020] like Figure 1 and Figure 2 As shown, a fixture for processing aviation parts includes a clamping mechanism 1, a flipping mechanism 2, a fixed seat 3 and a clamping mechanism 4; the clamping mechanism 1 includes a left clamping arm 11, a right clamping arm 12 and a clamping arm rod 13, and the inner sides of the left clamping arm 11 and the right clamping arm 12 are provided with anti-slip pads 14; the left clamping arm 11 and the right clamping arm 12 are slidably arranged on the clamping arm rod 13, and the left clamping arm 11 and the right clamping arm 12 are clamped and released by the clamping mechanism 4; the flipping mechanism 2 includes a flipping motor 21 and a motor seat 22, and the motor seat 22 is an L-shaped plate, and the flipping mechanism 2 is used to flip the clamping mechanism 1; the fixed seat 3 includes a horizontal bottom plate 31 and a column 32 vertically arranged on the horizontal bottom plate 31; the vertical plate section of the motor seat 22 is fixedly arranged on the side wall of the column 32, and the flipping motor 21 is fixedly arranged on the horizontal plate of the motor seat 22 The output shaft of the flip motor 21 is fixedly connected to the midpoint of the outer side surface of the clamping arm rod 13; the clamping mechanism 4 includes a clamping motor 41 and a clamping screw 42. The clamping arm rod 13 is hollow, and the clamping screw 42 is inserted into the clamping arm rod 13 along the length direction of the clamping arm rod 13. The clamping motor 41 is fixedly arranged on one end surface of the clamping arm rod 13, and one end of the clamping screw 42 is fixedly connected to the output shaft of the clamping motor 41. A clamping strip hole 131 for the left clamping arm 11 and the right clamping arm 12 to pass through is provided on the inner side surface of the clamping arm rod 13 along the length direction of the clamping arm rod 13. Both the left clamping arm 11 and the right clamping arm 12 pass through the clamping strip hole 131, and the tail ends are threadedly connected to the clamping screw 42. The internal threads on the left clamping arm 11 and the right clamping arm 12 are reversely arranged to realize simultaneous relative or opposite movement of the two.

[0021] By setting a flipping mechanism 2 to flip the clamping mechanism 1 as a whole, the reverse side of the part can be processed, which is very convenient. Compared with a multi-axis fixture in which each axis is driven by a driving mechanism, the clamping mechanism 1 is flipped as a whole, which avoids the problem of asynchronous flipping due to failure of any axis in the multi-axis. The structure is simple, the number of flipping parts is reduced, and the failure rate is reduced. The clamping motor 41 rotates to drive the clamping screw 42 to rotate. The clamping screw 42 rotates, and the tails of the left clamping arm 11 and the right clamping arm 12 are threadedly connected to the clamping screw 42, and the clamping strip hole 131 can limit the left clamping arm 11 and the right clamping arm 12 so that the left clamping arm 1 1 and the right clamp arm 12 will not rotate with the clamping screw 42. At this time, the left clamp arm 11 and the right clamp arm 12 will move on the clamping screw 42. Since the thread directions of the left clamp arm 11 and the right clamp arm 12 are opposite, the left clamp arm 11 and the right clamp arm 12 can move relative to each other to realize the clamping function and move away from each other to realize the loosening function. The clamping mechanism 1 is flipped by the flipping motor 21, which has a simple structure and is easy to operate. The motor seat 22 is set as an L-shaped plate to increase the connection area between the motor seat 22 and the column 32, thereby improving the stability of the connection. Anti-slip pads 14 are set on the inner sides of the left clamp arm 11 and the right clamp arm 12 to increase the friction between the parts and improve the stability of the clamping.

[0022] It should be noted that the inner side in this article refers to the side close to the part.
