Description

Technical Field

[0001] This utility model relates to a jig, specifically a jig for processing loudspeaker parts, and belongs to the field of loudspeaker part processing technology. Background Technology

[0002] In the loudspeaker manufacturing process, the processing precision of core components such as tweeter diaphragms, voice coil frames, terminal blocks, and frame edges directly determines the final acoustic performance and long-term service life of the loudspeaker. These components generally have thin-walled, irregularly shaped, and easily damaged structural characteristics. Among them, the tweeter diaphragm, as the core component for transmitting high-frequency sound waves, requires stamping to achieve precise structural forming and dimensions. This process must rely on specialized jigs. Only by utilizing the precise positioning, flexible clamping, and multi-specification adaptability of jigs can the problems of insufficient precision, component damage, low production efficiency, and difficulty in specification adaptation that easily occur when processing without jigs be solved, ultimately meeting the stringent requirements for processing core loudspeaker components.

[0003] For example, a diaphragm automatic stamping device is disclosed in patent CN211128192U, which uses a gripping component to unload the diaphragm. However, existing fixtures mostly use rigid metal blocks to directly clamp the diaphragm. For easily damaged parts such as ultra-thin diaphragms, rigid blocks can easily cause local stress concentration, leading to diaphragm wrinkles and edge cracks. Moreover, when processing tweeter diaphragms of different sizes, the entire set of clamping fixtures needs to be disassembled and replaced. The diaphragm guiding component and the limiting component need to be adjusted separately. This not only makes the production change operation cumbersome, but also easily leads to a decrease in the installation accuracy of the components due to repeated disassembly, which can easily cause the diaphragm to deviate during subsequent feeding. Utility Model Content

[0004] The purpose of this utility model is to provide a jig for processing speaker accessories in order to solve the above-mentioned problems. The limiting mechanism composed of electric push rod, slider, slide rod and connecting rod can flexibly adjust the distance of rubber pressure block, which can be adapted to speaker accessories of various specifications without frequent jig replacement. The hydraulic rod and rubber pressure block can output controllable pressure to ensure that the accessories are clamped firmly and do not shift and avoid overpressure damage. The through groove and slide groove of the base plate and the fixed plate provide precise guidance and anti-dislodgement limit for each component, reduce structural failures and ensure stable operation of the jig, thereby improving the processing accuracy and efficiency of speaker accessories.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a jig for processing speaker accessories, comprising a hydraulic cylinder, a support mechanism fixedly installed at the telescopic end of the hydraulic cylinder, a base plate and a fixed plate fixedly installed on the support mechanism, a through groove and a sliding groove provided in the base plate and the fixed plate, a limiting mechanism slidably installed between the base plate and the fixed plate, the limiting mechanism comprising an electric push rod and a slider, two electric push rods symmetrically fixedly installed on the top of the fixed plate, a slider fixedly connected to the telescopic end of the electric push rod, a sliding rod fixedly installed on the slider, both ends of the sliding rod located in the sliding groove, a connecting rod fixedly installed on the sliding rod, a hydraulic rod fixedly connected to the connecting rod, a rubber pressure block fixedly installed at the telescopic end of the hydraulic rod, and the top of the hydraulic rod located in the through groove.

[0006] Preferably, the slider and the hydraulic rod are slidably connected to the fixed plate, and the two ends of the slider are slidably connected to the base plate and the fixed plate, respectively.

[0007] Preferably, the rubber pressure block is arranged with an inclined structure, and the rubber pressure block is located on the bottom plate away from the slide rod.

[0008] Preferably, a plurality of rotating rods are equidistantly rotatably connected to the base plate, and the rotating rods are located between two sliding rods and two rubber pressure blocks.

[0009] Preferably, the width of the top of the hydraulic rod is greater than the width of the through groove, and the width of the slider is greater than the width of the slide groove.

[0010] Preferably, the support mechanism includes a push plate and a base, the extension end of the hydraulic cylinder is fixedly connected to the push plate, the base is fixedly installed on the push plate, and two columns are symmetrically fixedly connected to the top of the base.

[0011] Preferably, a base plate and a fixing plate are fixedly installed between the two columns, with the fixing plate located on top of the base plate.

[0012] Preferably, a guide mechanism is fixedly installed on the base plate. The guide mechanism includes a support plate and guide rods. The support plate abuts against the base plate. The support plate is inclined. A plurality of guide rods are rotatably installed at equal intervals inside the support plate.

[0013] Preferably, the guiding mechanism further includes a fixing frame, and two fixing frames are symmetrically fixedly installed at the bottom end of the base plate, and a support plate is fixedly installed on the fixing frame by bolts.

[0014] The beneficial effects of this utility model are as follows: the electric push rod can drive the slider to slide along the fixed plate, synchronously driving the slide rod to move in the slide groove. The position of the hydraulic rod and the rubber pressure block can be adjusted through linkage. This structure can flexibly change the distance between the two rubber pressure blocks. The two electric push rods are symmetrically arranged, and the slider and slide rod form a synchronous linkage structure through the linkage, ensuring that the rubber pressure blocks on both sides always move symmetrically when adjusted, avoiding unilateral offset that causes the part to be clamped eccentrically, and ensuring the dimensional accuracy of subsequent processing. The hydraulic rod, together with the rubber pressure block, flexibly clamps the part. The rubber pressure block directly acts on the part clamping part, and the linear extension and contraction characteristics of the hydraulic rod can ensure that the rubber pressure block applies force evenly. The slide groove provides lateral guidance for the slide rod, ensuring that the slide rod slides along a fixed trajectory when moving. The through groove provides vertical limit for the hydraulic rod, avoiding radial shaking when the hydraulic rod is pressed. The double groove cooperation makes the movement trajectory of each component accurate, reducing structural jamming or offset failures. Attached Figure Description

[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] Please see Figures 1-5 As shown, a jig for processing speaker accessories includes a hydraulic cylinder 1. A support mechanism 2 is fixedly installed at the telescopic end of the hydraulic cylinder 1. A base plate 3 and a fixed plate 4 are fixed on the support mechanism 2. The base plate 3 and the fixed plate 4 are provided with a through groove 8 and a sliding groove 9. A limiting mechanism 5 is slidably installed between the base plate 3 and the fixed plate 4. The limiting mechanism 5 includes an electric push rod 501 and a slider 502. Two electric push rods 501 are symmetrically fixedly installed on the top of the fixed plate 4. The telescopic end of the electric push rod 501 is fixedly connected to the slider 502. A sliding rod 503 is fixedly installed on the slider 502. The two ends of the sliding rod 503 are located in the sliding groove 9. A connecting rod 504 is fixedly installed on the sliding rod 503. A hydraulic rod 505 is fixedly connected to the connecting rod 504. A rubber pressure block 506 is fixedly installed on the telescopic end of the hydraulic rod 505. The top of the hydraulic rod 505 is located in the through groove 8. The telescopic end of the electric push rod 501 drives the slider 502 fixed thereto to slide laterally along the slide groove 9 of the fixed plate 4. When the slider 502 moves, it synchronously drives the slide rod 503 fixed at its bottom to slide along the slide groove 9 between the base plate 3 and the fixed plate 4. The connecting rod 504 fixed on the slide rod 503 moves with the slide rod 503. The hydraulic rod 505 fixed at the bottom of the linkage connecting rod 504 moves along the through groove 8 between the base plate 3 and the fixed plate 4 until the rubber pressure blocks 506 below the two hydraulic rods 505 are respectively aligned with the tweeter. With the electric push rod 501 closed at both edges of the diaphragm, the width of the slider 502 is greater than the width of the groove 9, and the top width of the hydraulic rod 505 is greater than the width of the through groove 8, preventing the slider 502 and hydraulic rod 505 from coming out of the groove, thus completing the clamping position adjustment; both the slider 502 and hydraulic rod 505 are slidably connected to the fixed plate 4, and both ends of the slide rod 503 are slidably connected to the base plate 3 and the fixed plate 4 respectively. The rubber pressure block 506 is set with an inclined structure and is located on the base plate 3 away from the slide rod 503. The hydraulic rod 505 is activated, and its telescopic end is slowly extended, driving the rubber pressure block 506 closer to the surface of the tweeter diaphragm. 6 has a sloping structure that can conform to the arc contour of the diaphragm edge until the rubber pad bonded to the bottom of the rubber pressure block 506 is in complete contact with the diaphragm surface. Adjust the output pressure of the hydraulic rod 505 to ensure that the diaphragm is clamped firmly. At the same time, the rubber pad prevents the rubber pressure block 506 from making direct hard contact with the diaphragm, preventing the diaphragm from being scratched or wrinkled. The width of the top of the hydraulic rod 505 is greater than the width of the through groove 8, and the width of the slider 502 is greater than the width of the slide groove 9. The punch presses the firmly clamped tweeter diaphragm. During this process, the base plate 3 and the fixing plate 4 are stably supported by the column 203. The slide groove 9 and the through groove 8 respectively limit the displacement of the slide rod 503 and the hydraulic rod 505 to prevent vibration from causing clamping deviation.

[0023] As a technical optimization of this utility model, a number of rotating rods 7 are equidistantly rotatably connected on the base plate 3. The rotating rods 7 are located between the two sliding rods 503 and the two rubber pressure blocks 506. After the diaphragm slides to the area of ​​the base plate 3, it continues to slide along the rotating rods 7 evenly distributed on the base plate 3. The rotating rods 7 are located between the two rubber pressure blocks 506, further guiding the diaphragm to accurately enter the clamping area until the center of the diaphragm is aligned with the punch axis of the stamping equipment, thus completing the feeding and positioning.

[0024] As a technical optimization of this utility model, the support mechanism 2 includes a push plate 201 and a base 202. The push plate 201 is fixedly connected to the telescopic end of the hydraulic cylinder 1. The base 202 is fixedly installed on the push plate 201. When the control switch of the hydraulic cylinder 1 is activated, the hydraulic cylinder 1 pushes the push plate 201 fixed at the telescopic end to move, and the base 202 fixed on the push plate 201 and the columns 203 symmetrically installed on the top of the base 202 move synchronously. Two columns 203 are symmetrically fixedly connected to the top of the base 202. A base plate 3 and a fixing plate 4 are fixedly installed between the two columns 203. The fixing plate 4 is located on the top of the base plate 3.

[0025] As a technical optimization of this utility model, a guide mechanism 6 is fixedly installed on the base plate 3. The guide mechanism 6 includes a support plate 601 and guide rods 602. The support plate 601 is in contact with the base plate 3. The support plate 601 is inclined. Several guide rods 602 are equidistantly rotatably installed inside the support plate 601. Take the tweeter diaphragm to be processed, put the edge of the diaphragm against the inclined support plate 601, and gently push the diaphragm. The diaphragm slides along the guide rods 602 rotatably connected to the support plate 601. The guide rods 602 rotate synchronously with the movement of the diaphragm, converting sliding friction into rolling friction and reducing scratches on the diaphragm surface. Two fixing brackets 603 are symmetrically fixedly installed at the bottom end of the base plate 3. The support plate 601 is fixedly installed on the fixing brackets 603 by bolts.

[0026] In use, the operator first symmetrically installs two hydraulic cylinders 1 at the bottom of the tweeter diaphragm stamping machine, then activates the control switch of the hydraulic cylinders 1. The hydraulic cylinders 1 push the push plate 201 fixed at the telescopic end to move, and the base 202 fixed on the push plate 201 and the column 203 symmetrically installed at the top of the base 202 move synchronously. Observe the position of the base plate 3 and the fixed plate 4 fixed on the column 203 until the base plate 3 is flush with the worktable of the stamping equipment, then close the hydraulic cylinders 1. Next, take the tweeter diaphragm to be processed, attach the edge of the diaphragm to the inclined support plate 601, and gently push the diaphragm. The diaphragm slides along the guide rod 602 rotatably connected to the support plate 601. 602 rotates synchronously with the diaphragm, converting sliding friction into rolling friction and reducing scratches on the diaphragm surface. After the diaphragm slides to the area of ​​the base plate 3, it continues to slide along the evenly distributed rotating rods 7 on the base plate 3. The rotating rods 7 are located between the two rubber pressure blocks 506, further guiding the diaphragm to accurately enter the clamping area until the center of the diaphragm is aligned with the punch axis of the stamping equipment, completing the loading and positioning. The two electric push rods 501 are activated. The telescopic ends of the electric push rods 501 drive the slider 502 fixed to them to slide laterally along the slide groove 9 of the fixed plate 4. When the slider 502 moves, it synchronously drives the slide rod 503 fixed at its bottom to slide along the slide groove 9 of the base plate 3 and the fixed plate 4. The connecting rod 504 fixed on the slide rod 503 moves with the slide rod. 503. Move the hydraulic rod 505, which is fixed at the bottom of the linkage 504, along the through groove 8 between the base plate 3 and the fixed plate 4 until the rubber pressure blocks 506 below the two hydraulic rods 505 are aligned with the two sides of the tweeter diaphragm. Close the electric push rod 501. At this time, the width of the slider 502 is greater than the width of the slide groove 9, and the top width of the hydraulic rod 505 is greater than the width of the through groove 8, to prevent the slider 502 and the hydraulic rod 505 from coming out of the groove, thus completing the clamping position adjustment. Start the hydraulic rod 505 and control its telescopic end to slowly extend, driving the rubber pressure block 506 closer to the surface of the tweeter diaphragm. The rubber pressure block 506 has a slanted structure, which can fit the arc contour of the edge of the diaphragm until the rubber pressure block 506 is bonded to the bottom of the diaphragm. The rubber pad fully contacts the diaphragm surface. The output pressure of the hydraulic rod 505 is adjusted to ensure that the diaphragm is firmly clamped. At the same time, the rubber pad prevents the rubber pressure block 506 from directly contacting the diaphragm, thus preventing scratches or wrinkles. The stamping equipment is started, and the punch presses the firmly clamped tweeter diaphragm. During this process, the base plate 3 and the fixing plate 4 are stably supported by the column 203. The slide groove 9 and the through groove 8 respectively limit the displacement of the slide rod 503 and the hydraulic rod 505 to prevent vibration from causing clamping deviation. After the stamping is completed, the hydraulic rod 505 is first controlled to retract, which drives the rubber pressure block 506 to detach from the diaphragm surface. The processed diaphragm is gently pushed, and the diaphragm slides along the rotating rod 7 of the base plate 3, and then slides out of the fixture through the guide rod 602, completing the unloading.
