Abstract
Description
Technical Field
[0001] This invention relates to a ceramic blank processing equipment, and more particularly to a ceramic blank milling and turning machining center. Background Technology
[0002] In ceramic jar processing, trimming involves placing the blank onto the trimming wheel of a potter's wheel, rotating the wheel, and using a knife to trim the blank to achieve the appropriate thickness and a smooth surface. This is a highly technical process. Trimming, also known as "refining" or "turning," is the crucial step in finalizing the shape of the vessel, ensuring a smooth surface, consistent form, and uniformity. Trimming workers not only need to be familiar with the properties of the clay but also to master the curves of the shape, the shrinkage ratio of different parts during firing, and the thickness of the clay left in each area. Generally, the thickness of the blank varies in different parts of the same vessel because the shrinkage rate and stress conditions differ in different areas during high-temperature firing. Therefore, the thickness of the clay blank in different parts must be controlled during trimming to prevent deformation during firing. Controlling and identifying the thickness of the blank during trimming is key to mastering trimming techniques and ensuring the quality of trimming.
[0003] The production of ceramic blanks is primarily done manually or with the aid of simple operating platforms. During the production process, the operator can only rely on their experience to judge the force and angle of processing. The finished ceramic blanks are greatly affected by human factors, and their shape and size are entirely determined by the operator. On the one hand, improper force can damage the ceramic blanks, and the shape and size of finished ceramic blanks in the same batch are uneven, with uneven surfaces, resulting in low yield and production efficiency. On the other hand, there is currently no processing equipment that can integrate the processes of trimming, milling, sanding, and watering, which is not conducive to the mass production of ceramics. Furthermore, most existing ceramic auxiliary processing devices require long-term manual operation, have low mechatronics integration, and are affected by the mental state and emotions of the operator. Manual operation has a certain error rate, making it difficult to improve the yield, resulting in high labor costs and low processing efficiency. Summary of the Invention
[0004] The purpose of this invention is to provide a ceramic blank milling and turning machining center that integrates the processes of ceramic blank trimming, milling, sanding, and water wiping into one CNC machining center, thereby greatly improving production efficiency.
[0005] The technical solution of this invention is: a ceramic blank milling and turning machining center, comprising a machine cover and a machine frame, characterized in that: it further comprises a positioning mechanism, a blank trimming mechanism, a carving and milling mechanism, a sanding mechanism, a water wiping mechanism, a gripping mechanism, and a ceramic blank rotation mechanism.

A servo motor mounted on the crossbeam drives the crossbeam to move up and down. The vertical lifting mechanism is mounted on a transverse guide rail on the upper beam of the frame via a slider and can move left and right along the upper beam. Six grippers are mounted on the crossbeam: a first positioning gripper, a second trimming gripper, a third milling gripper, a fourth sanding gripper, a fifth wiping gripper, and a sixth unloading gripper.

[0008] Further, the described ceramic blank milling and turning machining center is characterized in that: the blank trimming mechanism includes a blank trimming frame, a lower blank trimming tool holder, an upper blank trimming tool holder, and a blank trimming base plate. The blank trimming base plate is slidably mounted on the vertical rod corresponding to the blank trimming position of the machine frame and can move up and down along the vertical rod. The blank trimming frame is mounted on the blank trimming base plate. The upper and lower blank trimming tool holders are movably mounted on the blank trimming frame. The up and down movement of the blank trimming frame drives the upper and lower blank trimming tool holders to move up and down. The upper and lower blank trimming tool holders are connected to the blank trimming frame via guide rails, realizing the forward and backward movement of the upper and lower blank trimming tool holders. The upper and lower blank trimming tool holders can independently advance and deflect the blades.

[0012] Furthermore, the aforementioned ceramic blank milling and turning machining center is characterized in that: the positioning mechanism, blank trimming mechanism, milling and carving mechanism, sanding mechanism, and water wiping mechanism on the machine frame are fitted with bellows covers in the gap between the machine frame and the front and rear of the equipment, reducing the amount of dust from the front processing area entering the rear machine compartment and preventing the rear equipment from being contaminated and accelerating wear.
[0013] Furthermore, the ceramic blank milling and turning machining center is characterized by: including a waste discharge mechanism, which includes a guide plate, a conveyor belt, and a slag frame. The guide plate is installed on the turntable frame at the lower part of the turntable of the ceramic blank rotating mechanism. The transverse cross section of the guide plate is set as a triangle. The guide plate is the same length as the turntable frame and covers the upper part of the turntable frame, so that the slag falling from the turntable can fall down along the guide plate onto the slag conveyor belt. The conveyor belt transports the slag to the slag frame at the end.
[0014] Furthermore, the aforementioned ceramic blank milling and turning machining center is characterized by: further including a dust discharge mechanism, which is installed on the inner side of the upper front part of the machine cover, and the dust discharge mechanism includes a dust suction pump, which sucks the processing dust out of the machine.
[0015] A machining process for a ceramic blank turning and milling machining center includes steps such as loading, blank positioning, blank trimming, milling, sanding, watering, and unloading. The key feature is that loading, blank positioning, trimming, milling, sanding, watering, and unloading are performed simultaneously on a single machining center. The ceramic blank is first lifted from the loading table by a gripping mechanism using an expansion ball inserted into the lower end of the gripping arm. The crossbeam of the gripping mechanism rises under the action of a lifting mechanism, and then moves one position to the right under the action of a lateral movement mechanism, transferring the ceramic blank to the positioning turntable. Positioning is completed under the combined action of the gripping and positioning mechanisms. Afterwards, the gripping mechanism releases the ceramic blank and lifts it, then moves one position to the left. At each workstation, the gripping mechanism descends, and the first positioning gripper lifts a ceramic blank from the loading platform. Simultaneously, the second trimming gripper lifts a pre-positioned ceramic blank from the positioning turntable. The gripping mechanism then rises, moves one workstation to the right, and descends. At this point, the positioning mechanism positions the second ceramic blank, while the trimming mechanism trims the first ceramic blank. Once trimming is complete, the second ceramic blank is also positioned. The gripping mechanism then releases the ceramic blank and rises, moving laterally to the left and descending. The first positioning gripper grabs a third ceramic blank from the loading platform, while the second trimming gripper lifts the second blank, and the third trimming gripper lifts the first. The gripping mechanism then rises laterally, moves one workstation to the right, and descends, entering the workstation to begin processing. Once the slowest ceramic blank on the workstation has finished processing, the gripping mechanism releases all the ceramic blanks and rises. The gripping mechanism then moves laterally to the left and descends. The first positioning gripper arm grips the fourth ceramic blank on the loading platform. Simultaneously, the second trimming gripper arm lifts the third ceramic blank, the third trimming gripper arm lifts the second ceramic blank, and the fourth sanding gripper arm lifts the first ceramic blank. Afterward, the gripping mechanism rises laterally, moves one workstation to the right, and descends. Once in the workstation, processing begins. Once the slowest ceramic blank on the workstation has finished processing, the gripping mechanism releases the ceramic blank and rises. The gripping mechanism then moves laterally to the left and descends. The first positioning gripper arm grips the fifth ceramic blank on the loading platform. Simultaneously, the second trimming gripper arm lifts the fourth ceramic blank, the third trimming gripper arm lifts the third ceramic blank, and the fourth sanding gripper arm... The second ceramic blank is lifted, the fifth sanding gripper lifts the first ceramic blank, then the gripping mechanism rises horizontally, moves one station to the right, and descends. Each process begins processing. Once the slowest ceramic blank at the station is finished, the gripping mechanism lowers all ceramic blanks and rises, moves one station to the left, and descends. The gripping mechanism then lifts all ceramic blanks. At this time, the first positioning gripper grabs the sixth ceramic blank on the loading platform. Simultaneously, the second trimming gripper lifts the fifth ceramic blank, the third trimming gripper lifts the fourth ceramic blank, the fourth sanding gripper lifts the third ceramic blank, the fifth sanding gripper lifts the second ceramic blank, and the sixth gripper lifts the first ceramic blank. The gripper moves one station to the right and descends, releasing all ceramic blanks. At this time, the first finished ceramic blank appears on the receiving platform.The gripping mechanism moves one station to the left and descends. At this time, the positioning arm lifts a ceramic blank on the loading table, moves one station to the right, descends, and begins processing. Afterward, each time the gripping mechanism moves left, the first positioning arm retrieves a new ceramic blank; each time the gripping mechanism moves right, the sixth arm releases a new ceramic blank. This process repeats, and the machining center enters normal, stable processing.
[0016] The "refining" here refers to the shape of the ceramic blank after demolding. Some features cannot be achieved due to the characteristics of the mold itself and the ceramic material. For example, if the ceramic blank needs rounded corners or a concave shape, and the mold is concave, the ceramic blank cannot be demolded. This mold is a single-piece mold with a narrow opening at the bottom and a wider top. If other features are made, demolding becomes impossible because it lacks the necessary taper. The refining process of this invention aims to facilitate demolding while still creating sharp bottom features, concave corners, or thin-walled openings. These features cannot be accurately achieved with a mold, or the blank itself will still be somewhat soft and easily deformed during demolding. Therefore, it needs to be turned again using a lathe. This turning process is called refining. Refining allows for more precise and detailed product design and better demolding.
[0017] Milling is a process that uses CNC multi-tools to carve patterns on the surface of ceramic blanks.
[0018] Sanding is an additional process used to repair scars and burrs left over from the finishing and milling processes. It can repair scars and remove burrs.
[0019] Wiping with water involves using a cloth or sponge dipped in water to wipe the clay blank again, making the surface of the clay blank more intact.
[0020] The beneficial effects of this invention are as follows: It overcomes the shortcomings of manual production of ceramic blanks or production using simple operating platforms, which suffer from the inability of operators to control the processing force and angle, excessive influence of human factors on the finished ceramic blanks, and the fact that the shape and size of the finished ceramic blanks are entirely determined by the operator. It also addresses the problems of high labor intensity and high cost associated with manual production. This invention improves upon these issues by addressing the problems of ceramic blank damage due to improper force, uneven shape and size of finished ceramic blanks in the same batch, uneven surfaces, and low yield and production efficiency. Furthermore, it integrates the processes of blank trimming, milling, and water wiping into the same processing machine, enabling mass production of ceramics. It reduces the need for prolonged manual operation of auxiliary processing devices, improves the degree of mechatronics integration, reduces the rate of human error, reduces the influence of human mental state and emotions on the yield, significantly improves the yield, reduces labor costs, and increases production efficiency.

Afterwards, the gripping mechanism 1 releases the ceramic blank and lifts it, then moves one position to the left. Mechanism 1 descends, the first positioning gripper 2501 lifts a ceramic blank from the loading platform 18, and simultaneously the second trimming gripper 2502 lifts the already positioned ceramic blank from the positioning rotary table 17. The gripping mechanism 1 rises and lifts, then moves one station to the right before descending. At this time, the positioning mechanism 19 positions the second ceramic blank, and the trimming mechanism 20 trims the first ceramic blank. When the trimming is complete, the positioning of the second ceramic blank is also complete. The gripping mechanism 1 then releases the ceramic blank and rises, then moves laterally to the left and descends. The first positioning gripper 2501 grips a third ceramic blank from the loading platform 18, while the second trimming gripper 2502 lifts the second ceramic blank and the third trimming gripper 2503 lifts the first ceramic blank. Afterwards, the gripping mechanism 1 rises laterally, moves one station to the right, and descends. After entering the working position, it begins... Processing begins when the slowest ceramic blank on the workstation finishes processing. The gripping mechanism 1 releases all ceramic blanks and rises. Then, the gripping mechanism 1 moves laterally to the left and descends. The first positioning gripper arm 2501 grips the fourth ceramic blank on the loading platform 18. Simultaneously, the second trimming gripper arm 2502 lifts the third ceramic blank, the third trimming gripper arm 2503 lifts the second ceramic blank, and the fourth sanding gripper arm 2504 lifts the first ceramic blank. Afterward, the gripping mechanism 1 rises laterally, moves one workstation to the right, and descends. Once in the workstation, processing begins.

Then, the gripping mechanism 1 moves laterally to the left and descends. The first positioning gripper arm 2501 grips the fifth ceramic blank on the loading platform. Simultaneously, the second trimming gripper arm 2502 lifts the fourth ceramic blank, the third trimming gripper arm 2503 lifts the fourth ceramic blank, and the fourth sanding gripper arm 2504 lifts the first ceramic blank. The third ceramic blank is lifted by the fourth sanding gripper 2504, the second ceramic blank is lifted by the fifth sanding gripper 2505, and the first ceramic blank is lifted by the sixth sanding gripper 2506. Then, the gripping mechanism 1 rises horizontally, moves one station to the right, and descends. Each process begins processing. Once the slowest ceramic blank at each station is finished, the gripping mechanism 1 lowers all ceramic blanks and rises, then moves one station to the left and descends. The gripping mechanism 1 then picks up all the ceramic blanks and rises. At this point, the first positioning gripper 2501 picks up the sixth ceramic blank on the loading platform 18.

The gripping mechanism moves one station to the left and descends. At this time, the positioning arm lifts a ceramic blank on the loading platform, moves one station to the right, and descends to begin processing. Subsequently, each time the gripping mechanism moves to the left, the first positioning gripper arm 2501 retrieves a new ceramic blank, and each time the gripping mechanism moves to the right, the sixth gripper arm 2506 releases a new ceramic blank. This process is repeated, and the machining center enters normal and stable processing.
[0043] The gripping mechanism 1 lifts the ceramic blank from the loading platform using the tension ball 21 at the lower end of the gripping arm 25 of the gripping mechanism 1. The crossbeam 24 of the gripping mechanism 1 rises under the action of the lifting mechanism, and then moves one position to the right under the action of the lateral movement mechanism, transferring the ceramic blank to the positioning rotary table 17. Positioning is completed under the combined action of the gripping mechanism 1 and the positioning mechanism 19.
