[0015] 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.

[0016] Please see Figure 1-4 This utility model provides a technical solution: The sensor injection molding shell trimming device includes: a base plate 1, on which a support frame 2 is fixedly mounted; a fixing mechanism 3, which is disposed on the base plate 1 and the support frame 2, for fixing the injection molding shell; and a trimming mechanism 4, which is disposed on the top of the base plate 1. The trimming mechanism 4 includes a rotating component 41 and a trimming component 42. The trimming component 42 is disposed on top of the rotating component 41. The rotating component 41 drives the trimming component 42 to rotate, and trimming is performed on different positions of the injection molding shell. In this embodiment, the injection molded shell is fixed by the fixing mechanism 3, and then the injection molded shell is processed by the trimming component 42. Furthermore, by providing the rotating component 41, the trimming component 42 can be driven to rotate around the injection molded shell, which facilitates trimming processing at different positions of the injection molded shell, saving manpower and improving processing efficiency. The fixing mechanism 3 includes an electric push rod 31, a clamping block 32, a base 33, and two sets of anti-slip pads 34. The electric push rod 31 is fixedly installed on the top of the support frame 2. The bottom end of the output shaft of the electric push rod 31 passes through the support frame 2 and is fixedly connected to the clamping block 32. The base 33 is fixedly installed at the center of the top of the base plate 1. In this embodiment, a cylindrical, regular injection-molded shell is placed on the base 33, and then the output shaft of the electric push rod 31 is extended and retracted to drive the clamping block 32 to move and clamp and fix the injection-molded shell. The clamping block 32 is located directly above the base 33, and two sets of anti-slip pads 34 are respectively attached to the opposite ends of the clamping block 32 and the base 33; In this embodiment, the injection molded shell is located between two sets of anti-slip pads 34. The anti-slip pads 34 can be made of rubber to prevent damage to the injection molded shell. When the pressing block 32 squeezes the injection molded shell, the injection molded shell will squeeze the two sets of anti-slip pads 34, so that the injection molded shell is firmly pressed and prevented from moving during trimming. The rotating assembly 41 includes a gear disk 411, a drive gear 412, a first drive motor 413, several sets of support rods 414 and several sets of rollers 415. The gear disk 411 is rotatably mounted on the top of the base plate 1. The gear disk 411 meshes with the drive gear 412. One end of the output end of the first drive motor 413 is fixedly connected to the drive gear 412. In this embodiment, the output shaft of the first drive motor 413 drives the drive gear 412 connected to it to rotate, and the drive gear 412 drives the gear disk 411 meshing with it to rotate, thereby enabling the trimming assembly 42 to rotate around the injection molded shell, which facilitates trimming processing at different positions of the injection molded shell. The top of the base plate 1 is provided with a rotating groove that is compatible with several sets of support rods 414. Several sets of support rods 414 are arranged in a circular array inside the rotating groove. The top of several sets of support rods 414 is fixedly connected to the gear disk 411. Several sets of rollers 415 are respectively rolled on the bottom of several sets of support rods 414, and the rollers 415 are rolled on the inside of the rotating groove. In this embodiment, the gear disk 411 is supported by the support rod 414 and the roller 415. When the gear disk 411 rotates, it will drive the support rod 414 connected to it to rotate inside the rotating groove. At the same time, the roller 415 will roll inside the rotating groove, which helps to improve the stability of the gear disk 411 and thus improve the stability of the trimming assembly 42. The trimming assembly 42 includes a mounting frame 421, a trimming roller 422, and a second drive motor 423. The mounting frame 421 is fixedly mounted on the top of the gear disk 411, and the trimming roller 422 is rotatably mounted inside the mounting frame 421. The top end of the trimming roller 422 passes through the mounting frame 421 and is fixedly connected to the second drive motor 423. In this embodiment, the output end of the second drive motor 423 drives the trimming roller 422 connected to it to rotate inside the mounting frame 421 to trim the injection molded shell. It is worth noting that the injection molded shell to be processed should be fixed by the fixing mechanism so that it can be adapted to the trimming component 42, so as to facilitate the processing of the injection molded shell; The mounting bracket 421 is arranged in a U-shape, and a clearance groove adapted to the trimming roller 422 is provided on one side of the mounting bracket 421. In this embodiment, the clearance groove can make way for the trimming roller 422 to ensure the normal rotation of the trimming roller 422. In this application, the first drive motor 413 can be a Delta ECMA-C20604RS (servo motor), the second drive motor 423 can be a Dongling DLM-06L200 (high-speed DC motor), and the trimming roller 422 can be a customized dual-material composite roller, with an outer layer of 80-mesh silicon carbide grinding wheel (used to remove thick flash) and an inner layer of high-density nylon brush (used to clean burrs). The dual-material design can complete "rough trimming + fine trimming" in one go. The grinding wheel part quickly removes flash, and the brush part cleans residual burrs simultaneously, avoiding secondary processing. It is worth noting that this application is suitable for processing the outer cylindrical surface of shells with simple structures (without complex steps or holes). In an optional embodiment, a dust-collecting mechanism may be provided on the base plate to absorb the dust generated during trimming and prevent the dust from drifting away. The dust-collecting mechanism is prior art and therefore is not shown in this document.

[0017] Working principle: When this utility model is used, the injection molded shell is fixed by the fixing mechanism 3, and then the injection molded shell is processed by the trimming component 42. The rotating component 41 can drive the trimming component 42 to rotate around the injection molded shell, which facilitates trimming processing at different positions of the injection molded shell, saving manpower and improving processing efficiency.

[0018] 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.
