Abstract
Description
Technical Field
[0001] This utility model relates to the field of tooling and fixture technology, specifically to a tooling and fixture for processing magnesium alloy horns. Background Technology
[0002] Magnesium alloys are lightweight metals with high strength and rigidity. Their excellent thermal conductivity allows for rapid heat conduction and dissipation, making them advantageous in applications requiring superior heat dissipation. This allows magnesium alloy die-castings to maintain strength while reducing overall weight, making them suitable for applications requiring lightweight construction but demanding structural strength. Magnesium alloys also exhibit excellent corrosion resistance, particularly in atmospheric environments. This makes them widely applicable in outdoor and humid environments, and their good resistance to most common chemicals makes them a preferred material for applications requiring corrosion resistance.
[0003] Car audio horns, also known as vehicle loudspeakers, are a very common electroacoustic transducer that can be found in car audio systems. The brackets of existing car loudspeakers are made of metal, especially die-cast magnesium alloy, which can greatly improve the lifespan of the horn.
[0004] As is well known, after the horn bracket workpiece is die-cast, it is usually subjected to secondary processing until it meets the operational requirements. During this secondary processing, tooling fixtures are typically used to fix the workpiece, thereby improving its stability during machining. However, in existing technology, to improve workpiece stability, the entire circumference of the workpiece needs to be fixed. Fixing the workpiece requires using different fasteners individually, which is cumbersome and affects work efficiency to some extent. Utility Model Content

[0008] Furthermore, a sliding groove is provided on the worktable, the force-bearing block is slidably connected in the sliding groove, and a return spring is provided between the force-bearing block and the sliding groove.

[0023] 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.
[0024] Please see Figure 1-6 This utility model provides a technical solution: a tooling fixture for processing magnesium alloy horns, including a worktable 1, on which multiple sets of first clamping plates 2 are slidably connected, and a driving mechanism for driving the multiple sets of first clamping plates 2 to slide synchronously is provided on the worktable 1; the driving mechanism includes a driving plate 5 vertically slidably connected inside the worktable 1, and multiple sets of driving rods 7 are provided on the driving plate 5, with each driving rod 7 corresponding to a first clamping plate 2; a servo cylinder 4 for driving the driving plate 5 to slide vertically is provided inside the worktable 1; the worktable 1 is also provided with the same number of second clamping plates 3 as the first clamping plates 2, and each first clamping plate 2 and its corresponding second clamping plate 3 form a clamping space for clamping the workpiece.
[0025] Specifically, the tooling fixture for processing magnesium alloy horns includes a worktable 1, on which multiple sets of first clamping plates 2 are slidably connected. Specifically, there can be four first clamping plates 2, arranged around the perimeter of the worktable 1. The worktable 1 is equipped with a drive mechanism for synchronously sliding the multiple sets of first clamping plates 2, capable of simultaneously adjusting the state of the first clamping plates 2. The drive mechanism includes a drive plate 5 vertically slidably connected inside the worktable 1, with multiple sets of drive rods 7 on the drive plate 5, each drive rod 7 corresponding to a first clamping plate 2. A servo cylinder 4 is installed inside the worktable 1 to drive the drive plate 5 vertically. The worktable 1 also has the same number of second clamping plates 3 as the first clamping plates 2, with each first clamping plate 2 and its corresponding second clamping plate 3 forming a clamping space for holding the workpiece. Therefore, during use, the servo cylinder 4 drives the drive plate 5 to slide upward. During the upward sliding stroke of the drive plate 5, multiple sets of drive rods 7 slide upward, thereby driving the first clamping plate 2 to slide horizontally through the drive rods 7, so that the first clamping plate 2 moves closer to the second clamping plate 3 and fixes the workpiece located inside the clamping space. Therefore, there is no need to adjust the fasteners separately, which can further improve the practicality and work efficiency of the tooling fixture and is suitable for widespread use.
[0026] In the embodiments provided by this utility model, the drive rod 7 is fixedly connected to the drive plate 5 through the connecting rod 6, and the force block 8 is fixedly connected to the first clamping plate 2. The drive rod 7 and the force block 8 are adapted to each other. When the drive rod 7 slides upward, it drives the force block 8 to drive the first clamping plate 2 to slide horizontally, so that the state of the first clamping plate 2 can be adjusted according to the work needs.
[0027] In the embodiment provided by this utility model, a sliding groove is provided on the workbench 1, and the force-bearing block 8 is slidably connected in the sliding groove. A return spring 9 is provided between the force-bearing block 8 and the sliding groove. The elastic force of the return spring 9 drives the first clamping plate 2 and the second clamping plate 3 to move away from each other. Therefore, without the action of external force, the elastic force of the return spring 9 drives the first clamping plate 2 and the second clamping plate 3 to move away from each other, which facilitates the disassembly of the workpiece inside the clamping space.
[0028] In another embodiment of this utility model, an adapter groove is provided on the workbench 1, and a limiting block 11 is installed on the bottom of the second clamping plate 3. The second clamping plate 3 is slidably connected to the workbench 1 by the limiting block 11 sliding inside the adapter groove. The drive plate 5 and the limiting block 11 are connected by a linkage, which includes a positioning block 10 fixedly connected to the drive plate 5. The positioning block 10 and the limiting block 11 are rotatably connected by a hinged support rod 12. Therefore, during the stroke of driving the first clamping plate 2 to slide, the positioning block 10 will slide upward, and the limiting block 11 will slide through the hinged support rod 12, thereby driving the second clamping plate 3 to slide. This allows the first clamping plate 2 and the second clamping plate 3 to be tightly attached, fixing the workpiece and further improving the practicality of the tooling fixture.
[0029] In the embodiments provided by this utility model, a buffer element is provided between the second clamping plate 3 and the limiting block 11, which can clamp workpieces of different specifications according to work needs. The buffer element includes a buffer block 13 fixedly connected to the second clamping plate 3, a buffer groove 14 formed on the limiting block 11, the buffer block 13 slidably connected within the buffer groove 14, and a buffer spring 15 provided between the buffer block 13 and the buffer groove 14. The buffer element can buffer the operation and avoid motion interference.
[0030] In the embodiments provided by this utility model, a limiting unit is provided between the drive plate 5 and the worktable 1 to improve the stability of the drive plate 5 when it slides. The limiting unit is existing technology and can improve the stability of the drive plate 5 when it slides.
[0031] It should be noted that all electrical equipment involved in this application can be powered by batteries or external power sources.
[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
