Description

Technical Field

[0001] This utility model relates to the technical field of deburring equipment, specifically a deburring device for plastic speaker covers. Background Technology

[0002] Deburring equipment is a tool used to remove burrs from the surface of workpieces. Mechanical grinding is a process that uses high-speed rotating grinding wheels, abrasive belts, and other tools to rub the surface of workpieces to remove burrs. It is suitable for all kinds of workpieces, and the equipment is low in cost and easy to operate.

[0003] Mechanical equipment used for deburring plastic horn covers typically employs flexible abrasives, such as fine sandpaper, nylon grinding heads, or soft grinding wheels, to gently polish the workpiece surface. This type of equipment uses a motor to drive the abrasive to rotate or reciprocate at low speed, precisely contacting the burr areas and removing burrs while minimizing scratches on the plastic surface. However, because plastic horn covers are currently conical, deburring equipment cannot be well adapted to their surface, resulting in a cumbersome deburring process and low efficiency.

[0004] In view of this, we propose a deburring device for plastic horn covers. Utility Model Content

Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0031] Please see Figures 1-5 This utility model provides a technical solution:

[0032] A deburring device for plastic horn covers includes an operating table 1, an L-shaped frame 2 fixedly installed on the top of the operating table 1, two sets of L-shaped frames 2, and a sliding groove on the L-shaped frame 2, with the horn cover body 3 placed at the center of the top of the operating table 1.

[0033] In one embodiment of this utility model, a grinding assembly 4 is provided on the operating table 1. The grinding assembly 4 includes a bracket 41. The bracket 41 is fixedly installed at the bottom of the operating table 1. A dual-axis motor 42 is fixedly installed at the center of the bottom of the operating table 1. A rotating shaft 43 is rotatably installed inside the bracket 41 via bearing components. The output end of the dual-axis motor 42 is fixedly connected to one end of the rotating shaft 43, and the other end of the rotating shaft 43 is fixedly connected to a first bevel gear 44. A threaded rod 45 is rotatably installed inside the operating table 1 via bearing components. A second bevel gear 46 is fixedly installed at the bottom of the threaded rod 45 and meshes with the first bevel gear 44. Two sets of the bracket 41, dual-axis motor 42, rotating shaft 43, first bevel gear 44, threaded rod 45, and second bevel gear 46 are provided. 2. The output shaft rotates in the opposite direction. A threaded block 47 is threaded onto the threaded rod 45. One end of a connecting plate 48 is fixedly installed on the side wall of the threaded block 47. The connecting plate 48 slides against the inner wall of the L-shaped frame 2. The other end of the connecting plate 48 is fixedly connected to the base 49. A slide rail 410 is fixedly installed on the top of the base 49. An electric slider 411 is slidably installed on the outside of the slide rail 410. A vertical plate 412 is fixedly installed on the top of the electric slider 411. A second motor 413 is fixedly installed on one end of the vertical plate 412. An electric push rod 414 is fixedly installed on the other end of the vertical plate 412. The output end of the second motor 413 is fixedly connected to one end of the electric push rod 414. A grinding head 415 is fixedly installed on the other end of the electric push rod 414. The movement trajectory of the grinding head 415 conforms to the arc-shaped surface of the speaker cover body 3.

[0034] In this embodiment, two dual-axis motors 42 transmit power to the rotating shafts 43 through their output terminals, causing the two rotating shafts 43 to rotate in opposite directions. The first bevel gear 44 rotates synchronously with the rotating shafts 43. When the first bevel gear 44 rotates, it drives the second bevel gear 46, which in turn drives the two threaded rods 45 to rotate in the same direction. When the threaded rods 45 rotate, the threaded block 47 moves up and down along the axial direction of the threaded rods 45. The slide rail 410 provides a linear sliding track for the electric slider 411. The electric slider 411 slides on the slide rail 410 to achieve horizontal circumferential position adjustment. The second motor 413 outputs rotational power, which is transmitted to the electric slider 411 through its output terminal. The push rod 414 enables the electric push rod 414 to rotate. Through its internal telescopic structure, the electric push rod 414 extends and retracts to push the grinding head 415. The electric push rod 414 extends and retracts in a timely manner according to the arc curvature of the speaker cover body 3, pushing the grinding head 415 closer to the speaker cover, so that the grinding head 415 always fits against the arc surface of the speaker cover. During the grinding process, the second motor 413 drives the grinding head 415 to rotate. Through the rotation of the grinding head 415 and its movement close to the surface of the speaker cover body 3, and in conjunction with the grinding head 415 sliding circumferentially on the slide rail 410 via the electric slider 411, the burrs on the surface of the speaker cover body 3 are removed.

[0035] In one embodiment of this utility model, a support assembly 5 is provided on the operating table 1. The support assembly 5 includes a support column 51. The support column 51 is fixedly installed at the center of the top of the operating table 1. A sleeve 52 is fixedly installed on the outside of the support column 51. A telescopic rod 53 is sleeved inside the sleeve 52. A spring 54 is fixedly installed on the inner wall of the telescopic rod 53. A rubber block 55 is fixedly installed on the outside of the telescopic rod 53. Multiple sets of sleeves 52, telescopic rods 53 and springs 54 are provided. The lengths of the multiple sets of sleeves 52 and telescopic rods 53 are not the same, and the whole is trapezoidal from top to bottom (see reference). Figure 2 ).

[0036] In this embodiment, multiple sets of sleeves 52 and telescopic rods 53 are distributed along the axial direction of the support column 51, and their lengths decrease in a trapezoidal manner from top to bottom. This layout matches the geometric features of the conical outer surface of the horn cover body 3, ensuring that the ends of each telescopic rod 53 can simultaneously contact and fit against the conical surface of the horn cover body 3. When the horn cover body 3 is placed on the operating table 1, the conical surface first contacts the uppermost telescopic rod 53. As the horn cover body 3 moves downward, each layer of telescopic rods 53 is compressed in sequence, and the spring 54 undergoes elastic deformation and stores energy. The spring 54 acts evenly on the surface of the horn cover body 3 through the telescopic rods 53, forming multi-point elastic support, and the contacted rubber block 55 plays an anti-slip role, making the horn cover body 3 more firmly fixed.

[0037] All electrical components mentioned in this application are electrically connected to the PLC controller and 220V AC mains power. The PLC controller is a conventional and known device capable of controlling the dual-axis motor 42, electric slider 411, second motor 413, and electric push rod 414. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding, which are mature in the prior art. The standard parts are all conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art.
