Description

Technical Field

[0001] This utility model relates to the field of ceramic processing technology, specifically a blank trimming machine. Background Technology

[0002] A ceramic trimming machine is a type of mechanical equipment used in the production of ceramic products. It is mainly used for trimming, polishing, and fine processing of the formed ceramic blanks. It plays an important role in the ceramic production process, especially in the stages after the blank has dried and before glazing or firing. During trimming, the blank is placed on a post, rotated, and then turned with a cutting tool to make the blank smooth inside and out. After turning, the excess part at the bottom is trimmed off and the foot is removed, completing the various trimming processes.

[0003] Most existing blank trimming machines use a turntable to rotate the blank and trim the surface of the blank with trimming cutters. However, during the trimming process, the blank is subject to centrifugal force and is prone to micro-displacement. Furthermore, the cutting reaction force applied by the trimming cutters to the blank further exacerbates the blank displacement, resulting in uneven trimming thickness and inconsistent surface finish, thus leading to low trimming efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a blank trimming machine to solve the problems mentioned in the background art. Most of the existing blank trimming machines drive the blank to rotate through a turntable, and trim the blank surface through a trimming cutter. However, during the trimming process, the blank is prone to micro-displacement due to centrifugal force during rotation. Furthermore, the cutting reaction force applied by the trimming cutter to the blank further aggravates the blank displacement, resulting in uneven trimming thickness and inconsistent surface finish, which leads to low trimming efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a trimming machine, comprising a frame and a stabilizing unit:

[0006] The top of the frame has a turntable that rotates, and the bottom of the frame has a motor whose output end is connected to the bottom of the turntable. The stabilizing part is located inside the frame and has an adjusting plate that rotates inside the frame. The top of the frame has a moving frame that slides laterally, and the bottom of the moving frame has a slide rod that is embedded in the adjusting plate and slidably connected to the adjusting plate. The adjusting plate rotates to drive the slide rod to move horizontally. The moving frame has a roller that rotates vertically inside and abuts against the surface of the billet.

[0007] By adopting the above technical solution, the turntable can be driven by a motor to rotate, so that the billet can be kept rotating stably during the trimming process. At the same time, the rotation of the adjustment plate drives the slide bar to move horizontally, thereby adjusting the position of the moving frame, so that the roller always keeps in contact with the surface of the billet, improving the trimming accuracy and stability.

[0008] Preferably, the frame has a groove formed at the top of the frame, and a slider is provided on the side of the movable frame, which is embedded in the groove and slidably connected to the frame.

[0009] By adopting the above technical solution, the sliding frame can slide smoothly on the machine frame through the cooperation of the slider and the slide groove, reducing shaking and ensuring the stability of the contact between the roller and the billet.

[0010] Preferably, the stabilizing part has a guide groove formed on the top surface of the adjustment plate, the slide rod is embedded in the guide groove and slidably connected to the adjustment plate, and the side of the adjustment plate extends outward and is provided with an adjusting rod.

[0011] By adopting the above technical solution, the adjusting plate can be manually rotated by adjusting the rod, so that the slide bar can slide along the guide groove, thereby precisely controlling the lateral position of the moving frame and adapting to the blank trimming needs of blanks of different sizes.

[0012] Preferably, there are three movable frames, and the three movable frames are arranged in a central rotational symmetry structure around the rotation center of the adjustment plate.

[0013] By adopting the above technical solution, the symmetrical distribution of the three moving frames allows the rollers to support the billet evenly from multiple directions, avoiding uneven force during billet trimming that could lead to billet deformation or eccentricity.

[0014] Preferably, the stabilizing part also has a slide cylinder disposed on the top of the frame, a limit rod is vertically slidably disposed inside the slide cylinder, and a spring is disposed on the top of the limit rod, the spring being located inside the slide cylinder.

[0015] By adopting the above technical solution, the limiting rod can be made to slide up and down inside the slide cylinder by the elastic force of the spring.

[0016] Preferably, the stabilizing part also has a limiting groove formed on the surface of the slide cylinder, the limiting rod is embedded in the limiting groove and slidably connected to the limiting groove, and the limiting groove is inverted L-shaped.

[0017] By adopting the above technical solution, the sliding range of the limiting rod can be limited by the inverted L-shaped limiting groove, preventing it from moving too far down or detaching from the slide cylinder, while facilitating quick locking or releasing of the position of the limiting rod.

[0018] Preferably, the stabilizing part also has several fixing holes on the top of the adjustment plate, and the slide rod is embedded in the fixing holes and engaged with the adjustment plate.

[0019] By adopting the above technical solution, the position of the slide rod can be fixed after the adjusting plate is rotated into place through the locking connection between the fixing hole and the slide rod, thus preventing the moving frame from accidentally shifting during the blank trimming process and ensuring the stability of the blank trimming process.

[0020] Compared with the prior art, the beneficial effects of this utility model are: by setting a stabilizing part, the turntable can be driven by a motor to rotate, so that the billet can maintain stable rotation during the trimming process. At the same time, the rotation of the adjusting plate drives the sliding rod to move horizontally, thereby adjusting the position of the moving frame, so that the roller always fits the surface of the billet, improving the trimming accuracy and stability.

[0029] 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.

[0030] Example 1

[0031] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a blank trimming machine, including a frame 1 and a stabilizing unit 2.

[0032] A turntable 102 is rotatably mounted on the top of the frame 1, and a motor 103 is mounted on the bottom of the frame 1. The output end of the motor 103 is connected to the bottom of the turntable 102. The motor 103 is a servo motor, a high-precision, high-performance motor capable of precisely controlling position, speed, and acceleration. Its working principle is based on a closed-loop control system, mainly composed of a motor, encoder; or sensors and controller. The above is existing technology and will not be elaborated further. When selecting a model, its power should be matched to the requirements of the device to ensure that the object to be driven is driven.

[0033] The stabilizing unit 2 is located inside the frame 1. The stabilizing unit 2 has an adjusting plate 201 that is rotatably installed inside the frame 1. A movable frame 204 is slidably installed on the top of the frame 1. A sliding rod 206 is installed at the bottom of the movable frame 204. The sliding rod 206 is embedded inside the adjusting plate 201 and slidably connected to the adjusting plate 201. The adjusting plate 201 rotates to drive the sliding rod 206 to move horizontally. A roller 207 is vertically rotatably installed inside the movable frame 204. The roller 207 abuts against the surface of the billet. The turntable 102 can be driven to rotate by the motor 103, so that the billet can maintain stable rotation during the billet trimming process. At the same time, the rotation of the adjusting plate 201 drives the sliding rod 206 to move horizontally, thereby adjusting the position of the movable frame 204 so that the roller 207 always fits against the surface of the billet, improving the trimming accuracy and stability.

[0034] Example 2

[0035] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a blank trimming machine, including a stabilizing unit 2, an adjusting plate 201, and a moving frame 204.

[0036] A slide groove 101 is provided on the top of the frame 1, and a slider 205 is provided on the side of the movable frame 204. The slider 205 is embedded in the slide groove 101 and slidably connected to the frame 1. Through the cooperation of the slider 205 and the slide groove 101, the movable frame 204 can slide smoothly on the frame 1, reduce shaking, and ensure the stability of the contact between the roller 207 and the billet.

[0037] A guide groove 202 is provided on the top surface of the adjustment plate 201. The slide rod 206 is embedded in the guide groove 202 and slidably connected to the adjustment plate 201. The side of the adjustment plate 201 extends outward and is provided with an adjustment rod. The adjustment plate 201 can be manually rotated by adjusting the rod to make the slide rod 206 slide along the guide groove 202, thereby precisely controlling the lateral position of the moving frame 204 to adapt to the blank trimming needs of blanks of different sizes.

[0038] There are three movable frames 204. The three movable frames 204 are arranged in a central rotational symmetry structure around the rotation center of the adjustment plate 201. The symmetrical distribution of the three movable frames 204 can make the roller 207 support the billet evenly from multiple directions, avoiding uneven force during billet trimming, which may cause the billet to deform or become eccentric.

[0039] Example 3

[0040] Please see Figure 5 , Figure 6 and Figure 7 This embodiment provides a technical solution: a blank trimming machine, including a stabilizing part 2, a sliding cylinder 208, and a limiting rod 210.

[0041] A slide cylinder 208 is fixedly installed on the top of the frame 1. The fixing method is an existing detachable fixing, such as bolt connection, buckle connection, etc. A limit rod 210 is vertically slidably installed inside the slide cylinder 208. A spring 211 is installed on the top of the limit rod 210. The spring 211 is located inside the slide cylinder 208. The limit rod 210 can slide up and down inside the slide cylinder 208 by the elastic force of the spring 211.

[0042] A limiting groove 209 is formed on the surface of the slide cylinder 208. The limiting rod 210 is embedded in the limiting groove 209 and slidably connected to the limiting groove 209. The limiting groove 209 is inverted L-shaped. The sliding range of the limiting rod 210 can be limited by the inverted L-shaped limiting groove 209 to prevent it from moving too far down or falling off the slide cylinder 208. At the same time, it is convenient to quickly lock or release the position of the limiting rod 210.

[0043] Several fixing holes 203 are provided on the top of the adjustment plate 201. The slide rod 206 is embedded in the fixing holes 203 and engaged with the adjustment plate 201. The engagement between the slide rod 206 and the fixing holes 203 can fix the position of the slide rod 206 after the adjustment plate 201 is rotated into place, preventing the moving frame 204 from accidentally shifting during the blank trimming process and ensuring the stability of the blank trimming process.

[0044] Working Principle: First, the billet to be repaired is placed on the turntable 102, and the motor 103 is started to drive the turntable 102 to rotate, making the billet rotate at a uniform speed. Next, by manually rotating the adjusting rod of the adjusting plate 201, the sliding rod 206 is driven to slide along the guide groove 202, causing the moving frame 204 to move laterally along the sliding groove 101 until the roller 207 is in close contact with the surface of the billet. Then, the position of the adjusting limit rod 210 is rotated, causing the limit rod 210 to rotate and slide along the limiting groove 209. Through the elastic force provided by the spring 211, the limit rod 210 is pushed into the fixing hole 203, thereby fixing the position of the adjusting plate 201. This ensures that the roller 207 always contacts the billet with a constant pressure, preventing support failure due to changes in the height of the billet. The three symmetrically distributed moving frames 204 support the billet evenly from multiple directions through the roller 207. Combined with the stable rotation of the turntable 102, this ensures uniform force during billet repair and prevents the billet from deforming or becoming eccentric. When it is necessary to change to a blank of a different size, first move the limiting rod 210 upward along the limiting groove 209 to overcome the elastic force of the spring 211, release the engagement between the limiting rod 210 and the fixing hole 203, and then readjust the position of the moving frame 204 to quickly adapt.
