Abstract
Description
Technical Field
[0001] This utility model relates to the field of speaker machine ring component processing technology, and in particular to a fixture for processing speaker machine ring components. Background Technology
[0002] Speaker housing rings are typically used to form part of the frame or shell of a speaker, providing a stable support structure for other internal components such as speakers and circuit boards, ensuring that they maintain the correct position and relative relationship during operation.
[0003] When machining ring-shaped parts for speaker cabinets, external clamping fixtures are often used to fix the ring-shaped parts. However, since the contact area between the outer surface of the ring-shaped parts and the fixture is small, and the ring-shaped parts will generate vibration force during cutting, the ring-shaped parts are prone to displacement, which affects the cutting effect of the ring-shaped parts.
[0004] Therefore, a fixture for machining ring-shaped parts of speaker units is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a fixture for machining ring parts of speaker units in order to solve the above problems. It improves the problem that the contact area between the outer surface of the ring part and the fixture is small, and the ring part will generate vibration force during cutting, which can easily lead to the ring part shifting.
[0006] This utility model achieves the above-mentioned objective through the following technical solution: a fixture for machining ring-shaped parts of a speaker, comprising: a fixture base; and a clamping mechanism. The clamping mechanism includes a cylinder fixedly connected to the end of the fixture base. A conical block is fixedly connected to the top of the cylinder. An arc-shaped block is slidably connected to the upper surface of the fixture base, and the bottom of the arc-shaped block contacts the surface of the conical block. A limit frame is slidably connected to the upper end of the inner wall of the fixture base. A third spring is fixedly connected to the bottom of the limit frame, and the bottom end of the third spring is fixedly connected to the end of the fixture base. The third spring pushes the limit frame upward, thereby centering and limiting the ring-shaped part placed on the top of the fixture base. The upward movement of the top of the cylinder causes the conical block to move upward, thereby pushing the four arc-shaped blocks away from each other, so that the arc-shaped blocks press against the inner surface of the ring-shaped part, thus centering and clamping the ring-shaped part, preventing displacement of the ring-shaped part during cutting, and ensuring the cutting effect of the ring-shaped part.
[0007] Preferably, a rubber rod is slidably connected to the upper end of the inner wall of the fixture seat. The surface of the rubber rod is engaged with the inner wall of the limiting frame. A stop block is fixedly connected to one side of the fixture seat. A first spring is fixedly connected to the end of the rubber rod, and the other end of the first spring is fixedly connected to the upper end of the inner wall of the fixture seat. The rubber rod is moved and engaged into the limiting frame by the first spring, thereby limiting the limiting frame and preventing the limiting frame from being exposed at the top of the fixture seat, which would affect the cutting of the outer surface of the annular part.
[0008] Preferably, a movable block is rotatably connected to the upper surface of the clamping seat, and a fixed block is fixedly connected to the upper surface of the clamping seat. The movable block and the fixed block limit the movement of the rubber rod, ensuring that the rubber rod is stably engaged within the limiting frame.
[0009] Preferably, a second spring is fixedly connected to one side of the arc-shaped block, and the other end of the second spring is fixedly connected to the upper end of the inner wall of the clamp seat. The arc-shaped block is automatically reset by the second spring, thereby releasing the clamping of the annular part.
[0010] Preferably, elastic pads are fixedly connected to both sides of the arc-shaped block, and the other side of the elastic pad is fixedly connected to the upper end of the inner wall of the fixture seat. The elastic pads seal the open top of the fixture seat, thereby preventing debris generated during cutting from splashing onto the cylinder surface.
[0011] Preferably, both ends of the clamp seat are slidably connected to sealing blocks, and the inner wall of the clamp seat is slidably connected to an iron frame, the surface of which is engaged with the inner wall of the sealing blocks.
[0012] Preferably, a magnetic block is fixedly connected to one side of the fixture seat, and one side of the iron frame is magnetically attracted to one side of the magnetic block. Through the interaction between the magnetic block and the iron frame, the sealing block stably seals both ends of the fixture seat, thereby preventing debris generated during cutting from splashing onto the cylinder surface.
[0013] The beneficial effects of this utility model are:
[0014] 1. The third spring pushes the limit frame upward, thereby centering and limiting the ring-shaped part placed on the top of the fixture seat. The top of the cylinder moves upward, causing the conical block to move upward, which in turn pushes the four arc-shaped blocks away from each other, so that the arc-shaped blocks press against the inner surface of the ring-shaped part, thereby centering and clamping the ring-shaped part, thus increasing the contact area with the ring-shaped part, ensuring stable clamping of the ring-shaped part, and thus ensuring the cutting effect of the ring-shaped part;
[0015] 2. The rubber rod is moved and engaged in the limiting frame by the first spring, thereby limiting the limiting frame and preventing the limiting frame from being exposed on the top of the fixture seat, which would affect the cutting of the outer surface of the ring part.

[0021] 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.
[0022] In practical implementation: such as Figure 1-4 As shown, a fixture for machining ring-shaped parts of a speaker cabinet includes: a fixture base 1; and a clamping mechanism 2. The clamping mechanism 2 includes a cylinder 22 fixedly connected to the end of the fixture base 1. A conical block 23 is fixedly connected to the top of the cylinder 22. An arc-shaped block 21 is slidably connected to the upper surface of the fixture base 1, and the bottom of the arc-shaped block 21 contacts the surface of the conical block 23. A limit frame 24 is slidably connected to the upper end of the inner wall of the fixture base 1, and a third spring 26 is fixedly connected to the bottom of the limit frame 24. The bottom end of the third spring 26 is fixedly connected to the end of the fixture base 1. A rubber pad is fixedly connected to the surface of the arc-shaped block 21.
[0023] In this embodiment of the utility model, when the outer surface of the ring-shaped part of the speaker needs to be machined, the fixture seat 1 is installed on the worktable of the cutting machine tool by means of bolt and nut. The elastic force of the third spring 26 pushes the limit frame 24 to move upward, so that the upper surface of the limit frame 24 is exposed above the top of the fixture seat 1. The ring-shaped part is placed on the fixture seat 1, and the limit frame 24 centers and limits the placed ring-shaped part. At this time, the cylinder 22 is manually opened, and the top of the cylinder 22 moves upward, pushing the conical block 23 to move upward. The conical block 23 moves upward, pushing the four arc blocks 21 to move simultaneously, so that the four arc blocks 21 move away from each other and press against the inner surface of the ring-shaped part, thereby clamping the ring-shaped part. At this time, the cylinder 22 is manually closed and the limit frame 24 is pushed downward and retracted into the fixture seat 1.
[0024] At this time, the worker operates the CNC screen on the cutting machine tool. Through the CNC system in the CNC screen, the movement trajectory of each component on the cutting machine tool is automatically controlled. After adjusting the cutting tool to the appropriate cutting position, the cutting tool is driven to rotate, thereby cutting the outer surface of the ring part. During the cutting process, it is necessary to closely observe the cutting condition of the outer surface of the ring part, including dimensional accuracy, surface quality, and changes in cutting force. If dimensional deviations or surface quality problems are found, the cutting parameters or tools should be adjusted in time.
[0025] like Figure 3 As shown, a rubber rod 27 is slidably connected to the upper end of the inner wall of the clamp seat 1. The surface of the rubber rod 27 is engaged with the inner wall of the limiting frame 24. A stop block 25 is fixedly connected to one side of the clamp seat 1. A first spring 28 is fixedly connected to the end of the rubber rod 27. The other end of the first spring 28 is fixedly connected to the upper end of the inner wall of the clamp seat 1. A movable block 210 is rotatably connected to the upper end of the surface of the clamp seat 1. A fixed block 211 is fixedly connected to the upper end of the surface of the clamp seat 1.
[0026] In this embodiment of the utility model, the limiting frame 24 is pulled down to abut against the top of the abutment block 25. At this time, the elastic force of the first spring 28 pushes the rubber rod 27 to move and engage with the limiting frame 24. The movable block 210 is rotated so that the bottom of the movable block 210 abuts against the top of the fixed block 211, and one side of the movable block 210 contacts one end of the rubber rod 27, thereby limiting the rubber rod 27.
[0027] like Figure 3 As shown, a second spring 29 is fixedly connected to one side of the arc-shaped block 21, and the other end of the second spring 29 is fixedly connected to the upper end of the inner wall of the clamp seat 1. Elastic pads 212 are fixedly connected to both sides of the arc-shaped block 21, and the other side of the elastic pads 212 is fixedly connected to the upper end of the inner wall of the clamp seat 1. All elastic pads 212 are rubber components. The first spring 28, the second spring 29, and the third spring 26 are all 17-7PH stainless steel components.
[0028] In this embodiment of the utility model, after the cutting lathe has finished cutting the ring part, the cylinder 22 is manually opened. The top of the cylinder 22 moves down, causing the conical block 23 to move down. At this time, the elastic force of the second spring 29 pushes the arc block 21 to move away from the outer surface of the ring part, thereby releasing the clamping of the ring part, and the processed ring part can be taken out.
[0029] like Figure 4 As shown, both the front and rear ends of the clamp base 1 are slidably connected to the sealing blocks 215, and the inner wall of the clamp base 1 is slidably connected to the iron frame 213. The surface of the iron frame 213 is snapped into the inner wall of the sealing block 215. A magnetic block 214 is fixedly connected to one side of the clamp base 1, and one side of the iron frame 213 is magnetically attracted to one side of the magnetic block 214.
[0030] In this embodiment of the utility model, the sealing block 215 is slid into the clamp seat 1, and the iron frame 213 is pushed so that the iron frame 213 slides into the sealing block 215, so that one side of the iron frame 213 is attracted to the side of the magnetic block 214, thereby allowing the sealing block 215 to be installed on the clamp seat 1.
[0031] When this utility model is in use, the elastic force of the third spring 26 pushes the limiting frame 24 upward, so that the upper surface of the limiting frame 24 is exposed above the top of the clamp seat 1. The ring-shaped part is placed on the clamp seat 1, and the limiting frame 24 centers and limits the placed ring-shaped part. At this time, the cylinder 22 is manually opened, and the top of the cylinder 22 moves upward, pushing the conical block 23 upward. The upward movement of the conical block 23 pushes the four arc-shaped blocks 21 to move simultaneously, so that the four arc-shaped blocks 21 move away from each other and press against the inner surface of the ring-shaped part, thereby centering and clamping the ring-shaped part.
[0032] It should be noted that the fixture base 1, cylinder 22, iron frame 213 and magnetic block 214 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the cylinder 22 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
