Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, specifically a fixing fixture for machining metal inserts. Background Technology

[0002] Metal inserts are metal parts or components pre-embedded in polymer materials (such as plastics and rubber) during the molding process. Their function is to provide mechanical support, electrical and thermal conductivity, connection interfaces, or structural strength enhancement, enabling composite material products to possess both the functionality of metal and the processing convenience of polymer materials. In modern mechanical manufacturing, metal inserts are widely used as key components in industries such as automotive, aerospace, and electronics. From precision automotive engine components to high-strength structural parts for aerospace vehicles, the processing precision and quality of metal inserts directly determine the performance and reliability of the final product. As manufacturing moves towards higher precision, intelligence, and flexibility, higher requirements are placed on the fixtures used in the metal insert processing.

[0003] Traditional fixtures often employ manual positioning or simple mechanical positioning structures, such as relying on operator experience to adjust the position of inserts or using fixed slots for coarse positioning. This method is greatly affected by human factors, resulting in numerous positioning errors and making it difficult to meet the demands of high-precision machining.

[0004] Some traditional fixtures employ a single clamping method, such as simple bolt tightening or spring clamping. Under high-speed, high-cutting-force machining conditions, metal inserts are prone to displacement or vibration. For example, during milling, insert wobbling caused by unstable clamping can increase surface roughness, exceed dimensional and positional tolerances, reduce product yield, and increase rework rates. Furthermore, a single clamping structure is difficult to adapt to metal inserts of different shapes and sizes, requiring frequent fixture changes when changing product models, increasing equipment downtime and production costs. In addition, traditional fixtures are often designed for specific shapes and sizes of metal inserts, lacking versatility. When production tasks involve inserts of various specifications, companies need to equip themselves with multiple sets of dedicated fixtures, which not only occupy significant storage space but also involve cumbersome fixture replacement and adjustment processes, severely restricting production efficiency. Therefore, there is a need to design a fixed fixture specifically for the machining of metal inserts. Utility Model Content

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.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0020] Based on the existing problems of centering, clamping stability, and adaptability of metal inserts, this utility model provides a preferred embodiment of a fixing fixture for machining metal inserts, for example... Figure 1-4 As shown: A fixing fixture for machining metal inserts includes a mounting platform 1, a clamping seat 2 on the top of the mounting platform 1, four sets of mounting holes on the top of the clamping seat 2, located at the four corners, a fixing bolt 3 fixedly installed inside the mounting hole, and the fixing bolt 3 extending into the interior of the mounting platform 1, a control switch 4 fixedly installed on the front of the clamping seat 2; a centering clamping assembly 5, which is located inside and above the clamping seat 2; the centering clamping assembly 5 includes: a central part 51, which is located inside and above the clamping seat 2; and a clamping part 52, which is located above the clamping seat 2 and above the central part 51.

[0021] The central part 51 includes: a mounting groove 511, which is located at the top of the clamping seat 2; guide rods 512 are fixedly installed inside the mounting groove 511, and there are two sets of them arranged symmetrically; guide slide grooves 513 are provided on the inner side wall of the mounting groove 511, and there are two sets of them arranged symmetrically; slide columns 514 are slidably connected inside the guide slide grooves 513, and there are two sets of them.

[0022] Two sets of centering sliding plates 515 are fixedly installed between the sliding columns 514 and are movably sleeved on the outer wall of the guide rod 512. A limiting wear-resistant ring 516 is fixedly installed on the inner side wall of the centering sliding plate 515 and is sleeved on the outer wall of the guide rod 512.

[0023] An adjusting cylinder 517 is fixedly installed on the inner wall of the mounting groove 511, and the connecting end of the adjusting cylinder 517 is fixedly connected to the outer wall of the centering sliding plate 515 through a connecting rod. There are two sets of mounting columns 518 between the guide slides 513.

[0024] A rotating diagonal arm 519 is fixedly sleeved on the outer wall of the mounting column 518. One end of the rotating diagonal arm 519 is fixedly installed with a connecting arm 5110 by a fixing pin, and the other end of the connecting arm 5110 is sleeved on the outer wall of the sliding column 514. The other end of the rotating diagonal arm 519 is fixedly installed with a connecting arm 5111 by a fixing pin, and the other end of the connecting arm 5111 is sleeved on the outer wall of the sliding column 514. The connecting arm 5110 and the connecting arm 5111 are symmetrically arranged, and there are two sets in total. A centering connecting block 5112 is fixedly installed on the top of the centering sliding plate 515.

[0025] Furthermore, in this embodiment, an adjusting cylinder 517 drives the centering sliding plate 515 to move. With the precise guidance of the guide rod 512 and the guide groove 513, the centering sliding plate 515 moves smoothly in a straight line. At the same time, the linkage mechanism composed of connecting arm 1 5110, connecting arm 2 5111, and rotating diagonal arm 519 makes the centering sliding plates 515 on both sides move synchronously, accurately pushing the metal insert to the center position. Compared with traditional manual positioning fixtures, the positional deviation of the metal insert during the processing is reduced, effectively ensuring processing accuracy and reducing the scrap rate. Example

[0026] Please see Figures 1-4Furthermore, based on Embodiment 1, the clamping part 52 includes: a placement platform 521, which is fixedly installed on the top of the mounting groove 511; the top of the placement platform 521 is provided with sliding holes 522, and there are two sets in total, arranged symmetrically; the interior of the sliding hole 522 is slidably connected to a centering connecting block 5112; a clamping plate 523 is provided above the sliding hole 522, and the bottom of the clamping plate 523 is fixedly connected to the top of the centering connecting block 5112.

[0027] The inner sidewall of the clamping plate 523 is provided with semi-circular arc-shaped holes 524 at equal intervals, and the inner sidewall of the semi-circular arc-shaped holes 524 is provided with arc-shaped sliding grooves 525. Arc-shaped sliding plates 526 are slidably connected inside the arc-shaped sliding grooves 525.

[0028] A semi-circular clamping plate 527 is fixedly installed on the inner side wall of the arc-shaped sliding plate 526. A groove is provided on the inner side wall of the semi-circular clamping plate 527, and a small semi-circular clamping block 528 is slidably connected inside the groove. A sliding small semi-circular clamping block 529 is provided on the inner side wall of the small semi-circular clamping block 528 through a slidable connection, and the two are a group.

[0029] Furthermore, this embodiment features a multi-level adjustable clamping structure consisting of a semi-circular arc hole 524, an arc-shaped slide groove 525, an arc-shaped slide plate 526, a semi-circular clamping plate 527, a small semi-circular clamping block 528, and a sliding small semi-circular clamping block 529. This allows for flexible adjustment of the position of each component based on the shape and size of the metal insert, achieving a tight fit and clamping. This enables the clamp to hold irregularly shaped metal inserts of different sizes, expanding its applicability compared to single-structure clamps and meeting diverse processing needs.

[0030] In use, the operator first places the clamping seat 2 on the mounting platform 1 and secures it firmly to the top of the mounting platform 1 using the fixing bolts 3 in the mounting holes at the four corners. Then, the operator presses the control switch 4 on the front of the clamping seat 2 to power on the fixture and prepare it for subsequent operation.

[0031] Next, when positioning of the metal insert is required, control switch 4 issues a command to activate the adjusting cylinder 517 on the inner wall of the mounting groove 511. The piston rod of the adjusting cylinder 517 extends or retracts, driving the centering sliding plate 515 to move via the connecting rod. The centering sliding plate 515 is movably sleeved on the outer wall of the guide rod 512. At the same time, the sliding columns 514 on both sides of the centering sliding plate 515 slide within the guide groove 513. The guide rod 512 and the guide groove 513 provide precise guidance, ensuring that the centering sliding plate 515 moves smoothly and linearly, avoiding deviation.

[0032] Furthermore, as the centering sliding plate 515 moves, the connecting arm 1 5110 and connecting arm 2 5111, connected to the sliding column 514, rotate around the rotating diagonal arm 519 on the outer wall of the mounting column 518. Since connecting arm 1 5110, connecting arm 2 5111, and rotating diagonal arm 519 form a linkage mechanism, and the movements of the two sets of centering sliding plates 515 are interconnected, when the adjusting cylinder 517 drives one side of the centering sliding plate 515 to move, the other side of the centering sliding plate 515 will move synchronously in the opposite direction under the action of the linkage mechanism, thereby pushing the metal insert placed on the fixture towards the center position and completing the initial centering positioning. The limiting wear-resistant ring 516 is sleeved on the outer wall of the guide rod 512, which can reduce the friction between the centering sliding plate 515 and the guide rod 512 when moving, extend the service life of the component, and further ensure the stability of movement.

[0033] Furthermore, after the initial centering and positioning of the metal insert is completed at the centering part 51, the centering connecting block 5112 at the top of the centering sliding plate 515 moves upward along the sliding hole 522 at the top of the placement platform 521 under the action of the centering sliding plate 515, thereby driving the clamping plate 523, which is fixedly connected to the top of the centering connecting block 5112, to approach the metal insert. When the clamping plate 523 approaches the metal insert, the multi-level clamping structure composed of the semi-circular arc hole 524, arc-shaped sliding groove 525, arc-shaped sliding plate 526, semi-circular clamping plate 527, small semi-circular clamping block 528, and sliding small semi-circular clamping block 529 on its inner sidewall begins to function. The position of the semi-circular clamping plate 527 is adjusted by sliding the arc-shaped sliding plate 526 within the arc-shaped sliding groove 525. The small semi-circular clamping block 528 slides within the groove on the inner side wall of the semi-circular clamping plate 527, and the small semi-circular clamping block 529 also slides, ensuring the entire clamping structure fits tightly against the surface of the metal insert. This multi-level adjustable clamping method can adapt to metal inserts of different shapes and sizes, achieving a firm and precise clamping, preventing displacement or wobbling of the metal insert during machining, and ensuring machining accuracy.

[0034] Finally, after the metal insert is processed, the control switch 4 is operated again to retract the piston rod of the adjusting cylinder 517, causing the centering sliding plate 515 to move in the opposite direction, thereby moving the clamping plate 523 away from the metal insert. At the same time, the operator resets the semi-circular clamping plate 527, the small semi-circular clamping block 528, and the sliding small semi-circular clamping block 529, and the processed metal insert can be easily removed, completing one complete cycle of fixing, clamping, and processing operations.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
