Description

Technical Field

[0001] This application relates to the field of ceramic trimming technology, and in particular to a ceramic blank trimming machine. Background Technology

[0002] The ceramic body is the main part of the ceramic product, and its performance directly determines the performance and application of the ceramic product. After ceramic processing, the body needs to be trimmed. One of the main purposes of trimming is to smooth the uneven surface into a smooth surface.

[0003] While existing ceramic body trimming equipment on the market can perform basic trimming functions, problems still exist in practical applications. Most of the trimming components of existing trimming machines are designed with fixed angles, which cannot be flexibly adjusted according to the tilt angle of the ceramic body surface to be trimmed. For bodies with edges of different tilt angles or irregular curved surfaces, it is difficult for the trimming components to accurately fit the area to be trimmed, which can easily lead to local trimming omissions and trimming trajectory deviations. In addition, existing trimming equipment lacks an effective elastic adaptive structure, and the contact between the trimming components and the body surface is mostly rigid, making it difficult to guarantee the trimming effect. To solve the above problems, a ceramic body trimming machine is proposed. Utility Model Content

[0004] The purpose of this application is to provide a ceramic blank trimming machine that can more comprehensively adjust the position of the scraper, and at the same time adopts a flexible contact scraper, thus solving the problems in the prior art.

[0005] This application provides a ceramic blank trimming machine with the following technical solution: A ceramic blank trimming machine includes a base frame, a moving component, an electric push rod, an angle adjustment component, a trimming component, a rotating module, and a support platform. The moving component includes a slide rail fixedly connected to the upper surface of the base frame. A sleeve block is slidably fitted on the inner wall of the slide rail. A support block is fixedly connected to one side of the sleeve block. The bottom surface of the electric push rod is fixedly connected to the upper surface of the support block. The angle adjustment component includes a U-shaped frame fixedly connected to the output end of the electric push rod. An adjustable arm is installed on the inner wall of the U-shaped frame. A worm gear is fixedly connected to the rotating shaft end of the arm. A worm gear meshing with the worm gear is installed on the outer surface of the U-shaped frame. A second servo motor is fixedly connected to the outer surface of the U-shaped frame. The output shaft end of the second servo motor is fixedly connected to the rotating shaft end of the worm gear.

[0006] The trimming assembly includes an adjustment box fixedly connected to one end of the arm. A slide plate is slidably fitted on the inner wall of the adjustment box. A scraper is fixedly connected to one side of the outer surface of the slide plate, and two springs are fixedly connected to the other side of the outer surface of the slide plate. One end of each of the two springs is fixedly connected to the inner wall of the adjustment box.

[0007] By adopting the above technical solution, the second servo motor in the angle adjustment component drives the worm gear to rotate. The worm gear meshes with the worm wheel to drive the arm to rotate, which can accurately adjust the tilt angle of the trimming component, so that the scraper can be adapted to the surface of the ceramic blank with different tilt angles to be trimmed. The elastic force of the spring in the trimming component can push the slide plate to keep the scraper in contact with the surface of the blank, avoiding trimming omissions or over-trimming due to unevenness of the blank surface. The moving component drives the trimming-related parts to move as a whole, and in conjunction with the rotating module, drives the support table to rotate, so as to achieve comprehensive trimming of different positions of the blank. This solves the problems of fixed cutter head angle, difficulty in adapting to uneven surfaces, and limited trimming range of existing trimming machines.

[0008] Preferably, a first servo motor is fixedly connected to the outer surface of the slide rail, and a one-way lead screw is fixedly connected to the output shaft end of the first servo motor. The inner wall of the sleeve is threadedly connected to the outer surface of the one-way lead screw.

[0009] By adopting the above technical solution, the first servo motor drives the unidirectional lead screw to rotate. The rotation of the unidirectional lead screw causes the sleeve block to move linearly along the slide rail, which can flexibly adjust the position of the trimming component and facilitate stable trimming work.

[0010] Preferably, the inner wall of the slide rail is equipped with two symmetrical first guide posts, and the two sides of the sleeve block are slidably sleeved on the outer surfaces of the two first guide posts respectively.

[0011] By adopting the above technical solution, the sleeve block can be guided and limited on both sides, which can effectively limit the radial offset or shaking of the sleeve block during the movement along the unidirectional lead screw, ensure that the sleeve block always slides smoothly along the axis of the slide rail, and avoid the position displacement of the scraper during the trimming process caused by the shaking of the sleeve block.

[0012] Preferably, the inner wall of the adjustment box is fixedly connected with four limiting posts, and the four corners of the slide plate are respectively slidably sleeved on the outer surface of the four limiting posts.

[0013] By adopting the above technical solution, the four limiting posts position and guide the four corners of the slide plate, which can limit the movement trajectory of the scraper in the adjustment box, prevent the slide plate from tilting or deviating due to the elastic force of the spring, and ensure that the slide plate drives the scraper to always elastically fit in a direction perpendicular to the surface of the blank, so that the trimming force of the scraper is evenly distributed and the flatness of the blank surface after trimming is improved.

[0014] Preferably, the rotating module is fixedly connected to the upper surface of the base frame, the support platform is fixedly connected to the output end of the rotating module, a detachable top cover is installed on the top of the support platform, and a positioning component is provided between the support platform and the top cover.

[0015] By adopting the above technical solution, the top cover can be disassembled and installed on the top of the support platform, which facilitates subsequent cleaning work. The positioning component can position the bottom of the billet to ensure that the center of the billet is aligned with the rotation center of the rotating module, making it more practical.

[0016] Preferably, the positioning component includes a cavity formed inside the support platform, the inner wall of the cavity is rotatably connected to a bidirectional lead screw, the outer surface of the bidirectional lead screw is threaded with two symmetrical connecting blocks, and the top of each connecting block is equipped with a detachable arc plate.

[0017] By adopting the above technical solution, when the bidirectional lead screw rotates, it can drive the two connecting blocks to move synchronously relative to or opposite to each other along the axis of the bidirectional lead screw, thereby adjusting the distance between the two arc plates. This can adapt to ceramic blanks of different sizes and specifications, improve the adaptability of the equipment, and the arc structure of the arc plate can better fit the outer surface of the blank, increase the contact area during positioning, and improve the positioning firmness. At the same time, the arc plate can be disassembled, which can facilitate the cleaning of the cavity.

[0018] Preferably, the inner wall of the top cover is provided with two sets of symmetrical sliding grooves, and the outer surface of the connecting block is slidably fitted in the inner wall of the sliding groove.

[0019] By adopting the above technical solution, the groove on the inner wall of the top cover can limit and guide the top of the connecting block. When the connecting block moves with the bidirectional screw, it ensures that the two connecting blocks always move in parallel, so that the positioning of the two arc plates on the blank remains symmetrical, thereby ensuring the stability of the center of the blank during rotation trimming and improving the consistency of trimming.

[0020] Preferably, the inner wall of the cavity is fixedly connected to two second guide posts, and the two sides of the two connecting blocks are respectively slidably sleeved on the outer surfaces of the two second guide posts. The rotating shaft end of the bidirectional lead screw passes through the support and is fixedly connected to a knob.

[0021] By adopting the above technical solution, the two second guide posts form double-sided guides to the bottom of the connecting block, and cooperate with the sliding groove of the top cover to achieve smooth movement of the connecting block throughout its entire stroke. The knob at the end of the bidirectional lead screw allows the operator to directly and manually rotate the bidirectional lead screw to adjust the arc plate spacing without the need for additional tools, thus improving the ease of operation.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This ceramic blank trimming machine uses a second servo motor in the angle adjustment component to drive a worm gear that meshes with a worm wheel, causing the arm to rotate and adjusting the tilt angle of the trimming component. This allows the scraper to adapt to different tilt surfaces of the blank. The spring in the trimming component pushes the sliding plate, which, in conjunction with the guide pin, achieves flexible contact, ensuring the scraper always adheres to uneven surfaces and preventing trimming omissions or over-trimming, thus improving trimming quality. In the moving component, a first servo motor drives a one-way lead screw to move the sleeve block, which, in conjunction with an electric push rod, allows for more comprehensive adjustment of the trimming component's position. The positioning component positions the ceramic blank to be trimmed on the upper surface of the top cover. With the start-up rotation module, the blank can rotate, and the rotating blank can be trimmed by the scraper. This overall design solves the problems of fixed angles and rigid contact in existing equipment, making it more practical. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0026] Example 1: A ceramic blank trimming machine, referring to... Figure 1 , Figure 2 and Figure 4The system includes a base frame 1, a moving component 2, an electric push rod 3, an angle adjustment component 4, an edge trimming component 5, a rotating module 6, and a support platform 7. The moving component 2 includes a slide rail 201 fixedly connected to the upper surface of the base frame 1. A sleeve block 204 is slidably fitted on the inner wall of the slide rail 201. A support block 206 is fixedly connected to one side of the sleeve block 204. The bottom surface of the electric push rod 3 is fixedly connected to the upper surface of the support block 206. The angle adjustment component 4 includes a U-shaped frame 401 fixedly connected to the output end of the electric push rod 3. An adjustable arm 402 is installed on the inner wall of the U-shaped frame 401. A worm gear 403 is fixedly connected to the rotating shaft end of the arm 402. A worm 404 that meshes with the worm gear 403 is installed on the outer surface of the U-shaped frame 401. A second servo motor 405 is fixedly connected to the outer surface of the U-shaped frame 401. The output shaft end of the second servo motor 405 is fixedly connected to the rotating shaft end of the worm 404.

[0027] Reference Figure 2 , Figure 3 and Figure 5 The trimming assembly 5 includes an adjustment box 501 fixedly connected to one end of the arm 402. A slide plate 502 is slidably fitted onto the inner wall of the adjustment box 501. A scraper 503 is fixedly connected to one side of the outer surface of the slide plate 502, and two springs 504 are fixedly connected to the other side of the outer surface of the slide plate 502. One end of each spring 504 is fixedly connected to the inner wall of the adjustment box 501. Four limiting posts 505 are fixedly connected to the inner wall of the adjustment box 501. The four corners of the slide plate 502 are slidably fitted onto the outer surfaces of the four limiting posts 505. The four corners of the slide plate 502 are positioned and guided, which can limit the movement trajectory of the scraper 503 in the adjustment box 501, prevent the slide plate 502 from tilting or deviating due to the elastic force of the spring 504, and ensure that the slide plate 502 drives the scraper 503 to always elastically fit in a direction perpendicular to the surface of the blank, so that the trimming force of the scraper 503 is evenly distributed, and the flatness of the blank surface after trimming is improved. When the electric push rod 3 is started, the height of the U-shaped frame 401 can be adjusted. By adjusting the height of the U-shaped frame 401, the height of the scraper 503 can be changed.

[0028] Example 2: A ceramic blank trimming machine, referring to... Figure 1 , Figure 2 and Figure 3Based on the same concept as Embodiment 1 above, this embodiment proposes that a first servo motor 202 is fixedly connected to the outer surface of the slide rail 201, and a one-way lead screw 203 is fixedly connected to the output shaft end of the first servo motor 202. The inner wall of the sleeve 204 is threadedly connected to the outer surface of the one-way lead screw 203. The first servo motor 202 drives the one-way lead screw 203 to rotate. The rotation of the one-way lead screw 203 causes the sleeve 204 to move linearly along the slide rail 201, which can flexibly adjust the position of the trimming assembly 5 and facilitate stable movement. In the trimming process, two symmetrical first guide posts 205 are installed on the inner wall of the slide rail 201. The two sides of the sleeve block 204 are slidably sleeved on the outer surfaces of the two first guide posts 205, which can form a double-sided guide limit for the sleeve block 204. This can effectively limit the radial offset or shaking of the sleeve block 204 during the movement along the unidirectional lead screw 203, ensuring that the sleeve block 204 always slides smoothly along the axial direction of the slide rail 201, and avoiding the position displacement of the scraper 503 during the trimming process due to the shaking of the sleeve block 204.

[0029] Reference Figure 1 , Figure 3 and Figure 5 The rotating module 6 is fixedly connected to the upper surface of the base frame 1. The interior of the rotating module 6 consists of a drive motor and a rotating shaft fixedly connected to the output end of the drive motor. Since the rotating module 6 is an existing component, it is not marked in detail in the figure. The support platform 7 is fixedly connected to the output end of the rotating module 6. A detachable top cover 8 is installed on the top of the support platform 7. A positioning component 9 is provided between the support platform 7 and the top cover 8. The top cover 8 can be removed and installed from the top of the support platform 7, which facilitates subsequent cleaning. The positioning component 9 can position the bottom of the billet to ensure that the center of the billet is aligned with the rotation center of the rotating module 6, which is more practical. The positioning component 9 includes a cavity 901 opened inside the support platform 7. The inner wall of the cavity 901 A bidirectional lead screw 902 is rotatably connected, and two symmetrical connecting blocks 903 are threadedly connected to the outer surface of the bidirectional lead screw 902. Each connecting block 903 has a detachable arc-shaped plate 904 installed at its top. When the bidirectional lead screw 902 rotates, it can drive the two connecting blocks 903 to move synchronously relative to or opposite to each other along the axis of the bidirectional lead screw 902, thereby adjusting the distance between the two arc-shaped plates 904. This allows it to adapt to ceramic blanks of different sizes and specifications, improving the adaptability of the equipment. The arc-shaped structure of the arc-shaped plate 904 can better fit the outer surface of the blank, increasing the contact area during positioning and improving the stability of positioning. At the same time, the arc-shaped plate 904 can be detached, which facilitates the cleaning of the inside of the cavity 901.

[0030] Reference Figure 1 , Figure 3 and Figure 5The inner wall of the top cover 8 has two sets of symmetrical sliding grooves 905. The outer surface of the connecting block 903 is slidably fitted in the inner wall of the sliding groove 905. The sliding groove 905 on the inner wall of the top cover 8 can limit and guide the top of the connecting block 903. When the connecting block 903 moves with the bidirectional lead screw 902, it ensures that the two connecting blocks 903 always move in parallel, so that the positioning of the two arc plates 904 on the blank remains symmetrical, thereby ensuring the stability of the blank's center during rotary trimming and improving the consistency of trimming. The inner wall of the cavity 901 is fixedly connected to two second guide posts 90. 6. The two connecting blocks 903 are slidably sleeved on the outer surfaces of the two second guide posts 906 on both sides. The rotating shaft end of the bidirectional screw 902 passes through the support 7 and is fixedly connected to a knob 907. The two second guide posts 906 form a double-sided guide for the bottom of the connecting block 903, which cooperates with the sliding groove 905 of the top cover 8 to realize the smooth movement of the connecting block 903 throughout its entire stroke. The knob 907 at the end of the bidirectional screw 902 allows the operator to directly and manually rotate the bidirectional screw 902 to adjust the spacing of the arc plate 904 without the need for additional tools, thus improving the ease of operation.

[0031] The implementation principle of this application embodiment is as follows: The ceramic blank to be trimmed is placed on the top cover 8. The knob 907 is manually turned to drive the bidirectional lead screw 902 to rotate in the cavity 901. When the bidirectional lead screw 902 rotates, it drives the two connecting blocks 903 to move relative to each other along the second guide post 906, thereby driving the arc plate 904 to clamp the blank. At the same time, the sliding groove 905 on the inner wall of the top cover 8 limits and guides the top of the connecting block 903, ensuring that the two arc plates 904 symmetrically fit the surface of the blank, so that the center of the blank is precisely aligned with the rotation center of the rotating module 6, and the positioning is completed. Then, according to the trimming requirements of the blank, the height of the trimming component 5 is adjusted by pushing the support block 206 through the electric push rod 3. The second servo motor 405 is started to drive the worm gear 404 to rotate. The worm gear 404 meshes with the worm wheel 403 to drive the arm 4. 02. Rotate within the U-shaped frame 401 to adjust the tilt angle of the trimming component 5, so that the scraper 503 adapts to the tilt of the surface of the blank to be trimmed. Then, start the first servo motor 202 and the rotation module 6. The first servo motor 202 drives the one-way lead screw 203 to rotate, causing the sleeve block 204 to move smoothly along the slide rail 201 until the scraper 503 contacts the uneven surface of the blank. Then, with the help of the rotation module 6, drive the support table 7, the top cover 8 and the blank to rotate at a uniform speed. During the trimming process, the spring 504 in the adjustment box 501 continuously provides elastic force to push the slide plate 502, so that the scraper 503 always elastically fits the surface of the blank. The four limit posts 505 position and guide the four corners of the slide plate 502 to prevent the slide plate 502 from tilting or shifting, ensuring that the trimming force is uniform and adapts to the uneven surface of the blank. After the trimming is completed, turn the knob 907 in the opposite direction to release the arc plate 904, take out the trimmed blank, and with the help of the detachable arc plate 904 and top cover 8, the residual ceramic debris in the cavity 901 can be easily cleaned. The whole process is smooth and efficient, simple to operate and precise in trimming.
