Description

Technical Field

[0001] This invention specifically relates to a grinding fixture for removing material through cutting. Background Technology

[0002] Existing electric toothbrushes, in addition to their brushing function, can also detect cavities by installing a cavity detector. However, the replacement of the dual-purpose brush heads in current electric toothbrushes is relatively simple, involving only pulling and inserting. This can easily lead to instability in the electrical connection structure of the cavity detector. In other words, the electrical connection structure of the cavity detector relies solely on pin contact, lacking a position-fixing structure to secure the detector's installation location. This can result in unstable telecommunication signal transmission, affecting the effectiveness of the detection. Furthermore, existing electric toothbrushes use a wireless Wi-Fi smart module to transmit data to an application software displayed on a mobile phone. Image analysis and report generation cannot be completed within the electric toothbrush itself; the computational tasks must be handled by the mobile phone and server. This lack of independent computational functionality negatively impacts the user experience. Summary of the Invention

[0019] The components include: a grinding fixture 10 for cutting and removing material, a fitting fixture 11, a long groove 111, a sliding groove 112, a support part 113, a positioning fixture 12, an outer arc-shaped grinder 13, a light sensor 14, an outer screw 15, an outer drive motor 16, an outer nut 17, an inner arc-shaped grinder 18, an inner guide rail 19, an inner screw 20, an inner drive motor 21, an inner nut 22, a clamping block 23, a fixing seat 24, a guide part 241, a slide rail 25, an end grinder 26, an end drive motor 27, an end screw 28, an end nut 29, a connecting block 30, a laser emitter 31, and a guide rail 32. Detailed Implementation

[0020] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0021] like Figures 1 to 3 The illustration reveals a grinding fixture 10 for removing material, comprising: a bonding fixture 11, a positioning fixture 12, an inner arc-shaped grinder 18, and an outer arc-shaped grinder 13. The bonding fixture 11 is used to bond to the outer surface of a curved composite material molding part. The positioning fixture 12 is used to position the curved composite material molding part to limit its length. The inner arc-shaped grinder 18 is used to grind the inner side of the curved composite material molding part, and the outer arc-shaped grinder 13 is used to grind the outer side of the curved composite material molding part. The positioning fixture 12 is fixed to the inner side of the bonding fixture 11. A guide rail 32 is provided on the upper end face of the bonding fixture 11 to guide the inner arc-shaped grinder 18 to slide along the extension direction of the bonding fixture 11. An inner drive assembly is provided at one end of the guide rail 32 to drive the inner arc-shaped grinder 18 to slide along the guide rail 32, thereby achieving grinding of the inner side of the curved composite material molding part.

[0022] During installation, the outer arc-shaped grinder 13 is slidably connected to the inner side of the fitting fixture 11. An external drive assembly is mounted on the fitting fixture 11 to drive the outer arc-shaped grinder 13 to slide along the extension direction of the fitting fixture 11, thereby achieving back-and-forth grinding of the outer periphery of the curved composite molding part. The fitting fixture 11 has a long groove 111 to accommodate the outer arc-shaped grinder 13 for movement and grinding, thus ensuring smooth grinding of the outer side while reducing the overall installation volume of the fixture. Specifically, the external drive assembly includes two sliding grooves 112, two external screws 15, and two external drive motors 16. The two sliding grooves 112 are respectively formed on both sides of the long groove 111 of the fitting fixture 11. During installation, the two external screws 15 are rotatably mounted on the outer sides of the fitting fixture 11 located on both sides of the long groove 111, and the two external screws 15 are respectively arranged parallel to the corresponding sliding grooves 112. The two ends of the outer arc-shaped grinder 13 are slidably connected to two grooves 112, and the two ends of the outer arc-shaped grinder 13 are respectively threaded onto the outer periphery of two outer screws 15 by outer nuts 17. Two external drive motors 16 are respectively installed on both sides of the end of the fitting fixture 11, and the motor shafts of the external drive motors 16 are respectively connected to the end of the corresponding outer screws 15. In this way, when the curved composite material is inserted into the fitting fixture 11, the outer nuts can be driven to move along the outer screws 15 by simultaneously driving the external drive motors 16, thereby driving the outer arc-shaped grinder 13 to move along the outer periphery of the curved composite material, and thus grinding the outer side of the curved composite material.

[0023] Furthermore, the internal drive assembly includes: two inner guide rails 19, two inner screws 20, and two internal drive motors 21. During installation, the two inner guide rails 19 are respectively mounted on the upper ends of both sides of the fitting fixture 11, and the two inner screws 20 are rotatably mounted on the upper ends of both sides of the fitting fixture 11, with the two inner screws 20 arranged parallel to their respective inner guide rails 19. The two ends of the inner arc-shaped grinder 18 are slidably fitted onto the outer circumference of the two inner guide rails 19, and the two ends of the inner arc-shaped grinder 18 are respectively connected to inner nuts 22 via connecting rods. The inner nuts 22 are threaded onto the outer circumference of the two inner screws 20, meaning that the two ends of the inner arc-shaped grinder 18 are threaded onto the outer circumference of the two inner screws 20. The two internal drive motors 21 are respectively mounted on both sides of the other end of the fitting fixture 11, and the motor shafts of the two internal drive motors 21 are respectively connected to the ends of the corresponding inner screws 20. When the curved composite material is inserted into the fitting fixture 11, the inner drive motor 21 can drive the inner nut 22 to move along the inner screw 20, thereby driving the inner arc-shaped grinder 18 to move along the inner circumference of the curved composite material, and then the outer side of the curved composite material is ground by the inner arc-shaped grinder 18.

[0024] The above solution limits the length of the curved composite molding part by the distance from the positioning fixture 12 to one end of the fitting fixture 11. The length of the curved composite molding part can be effectively determined by cutting along one end of the fitting fixture 11.

[0025] In the design, the inner arc-shaped grinder 18 is embedded inside the positioning fixture 12 when it is located at one end of the guide rail 32, and the outer arc-shaped grinder 13 is sleeved on the outside of the positioning fixture 12 when it is located at one end of the guide rail 32. The thickness of the portion of the positioning fixture 12 located inside the fitting fixture 11 is equal to the standard thickness of the curved composite molded part to be ground. This design allows for precise grinding of the outer and inner circumferences of the curved composite molded part without any thickness measurement, ensuring accurate thickness values ​​after grinding. The simple automatic grinding structure achieves efficient grinding without the need for manual measurement or additional thickness sensors, effectively guaranteeing the installation accuracy of the curved composite molded part while maintaining low cost.

[0026] In one specific implementation, a support portion 113 is formed at the end of the fitting fixture 11 that is away from the positioning fixture 12. The support portion 113 can support the curved composite material to be ground. The thickness of the support portion 113 is equal to the grinding diameter of the outer arc-shaped grinder 13. A clamping block 23 is installed on the upper end of the positioning fixture 12 at each of the two sides corresponding to the curved composite material to be ground. The clamping block 23 can clamp and limit the curved composite material to be ground. This ensures precise and stable grinding position of the curved composite material during grinding, thereby guaranteeing grinding accuracy. Through the combined effects of gravity and double levers, the front and rear edges of the curved composite material can be fully ground, reducing blind spots.

[0027] In one specific implementation, the fitting fixture 11 has two fixed seats 24 at the end away from the positioning fixture 12. A slide rail 25 is provided between each fixed seat 24 and its corresponding clamping block 23. An end grinder 26 is slidably connected to the slide rail 25 for grinding the upper surface of the curved composite molding part to be ground. An end drive assembly is mounted on the fixed seat 24 to drive the end grinder 26 to move along the slide rail 25. Specifically, the end drive assembly includes an end drive motor 27, an end screw 28, an end nut 29, and a connecting block 30. The connecting block 30 is slidably fitted onto the outer periphery of the slide rail 25 and fixedly connected to the end nut 29. The two ends of the end screw 28 are rotatably connected to the fixed seat 24 and the clamping block 23, respectively. The end drive motor 27 is mounted on the fixed seat 24, and its motor shaft is connected to one end of the end screw 28. In this way, when the curved composite material is inserted into the fitting fixture 11, the end drive motor 27 can drive the end nut 29 to move along the end screw 28, thereby driving the end grinder 26 to move along both ends of the curved composite material, and then the end grinder 26 grinds both ends of the curved composite material, thereby improving the overall installation accuracy of the curved composite material.

[0028] As a specific implementation, a laser emitter 31 is provided on the fixed base 24. The laser emitter 31 emits a laser to irradiate the cutting position of the curved composite molding part to mark the cutting position. Then, the cutting tool is used to cut the end of the curved composite molding part along the laser irradiation point and in contact with the end of the above-mentioned fitting fixture 11. This can effectively improve the cutting accuracy.

[0029] In one specific implementation, the fixing seat 24 is provided with a guide portion 241, which can guide the curved composite material to be ground into the fitting fixture 11. At the same time, it can also limit and press one end of the curved composite material to be ground to ensure the stability of the grinding and cutting operation.

[0030] Furthermore, a light sensor 14 is embedded in the side of the positioning fixture 12 that contacts the curved composite material to be polished. The light sensor 14 is communicatively connected to the external drive motor 16, the internal drive motor 21, and the end drive motor 27. The installation position of the curved composite material can be detected by the light sensor 14. That is, when the curved composite material is inserted into the fitting fixture 11 to the designated position, it completely blocks the light sensor 14. After the light sensor 14 can no longer detect light, it sends a signal to the external drive motor 16, the internal drive motor 21, and the end drive motor 27 to control the external drive motor 16, the internal drive motor 21, and the end drive motor 27 to perform the polishing operation. The number of polishing operations and the polishing direction can be set according to the actual situation.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
