Description

Technical Field

[0001] The invention relates to the technical field of ceramics, and in particular to a batch clamping fixture and a processing method for cylindrical ceramic green bodies. Background Art

[0002] Ceramic green body processing refers to the processing of various shapes and sizes of ceramic materials before the sintering process. In the traditional ceramic product processing process, the ceramic material needs to be sintered first, and then the workpiece is processed by mechanical processing methods such as grinding, milling, and drilling. This process is not only time-consuming, but also has high requirements on equipment. Ceramic green body processing can be directly processed on unsintered ceramic materials, greatly shortening the processing cycle and production costs. In addition, due to the low hardness of ceramic green body materials, the machine tool can use larger feed parameters during processing, so the processing efficiency and flexibility are higher.

[0003] During the processing of cylindrical ceramic green bodies on machining center machines, fixtures are required to clamp and fix them. However, the ceramic green body material itself is very brittle, and improper clamping of the material can easily cause cracks and breakage.

[0004] At present, tools such as flat-nose pliers and C-type clamps are commonly used for clamping and fixing. Such tools and ceramic green bodies are in rigid contact, and improper operation can easily cause cracks and gaps in the material. In addition, tools such as flat-nose pliers can only clamp one ceramic product at a time, and batch clamping and processing cannot be achieved, resulting in low processing efficiency. Summary of the invention

[0036] The linear guide rail assemblies 3 are arranged in three groups in parallel, and are respectively arranged on the plate surface at both ends and the middle position of the bottom plate 12 along a direction perpendicular to the length of the bottom plate 12 .

[0037] Each linear guide assembly 3 includes a guide rail 31 and a slider assembly 32 slidably disposed on the guide rail 31. The slider assembly 32 includes two sliders, and the slider assembly in the three linear guide assemblies 3 is divided into a positioning support assembly moving slider 33 and a movable pressure block assembly locking moving slider 34 along the length direction of the bottom plate 12.

[0039] The limit blocks 8 are arranged on both sides of the adjusting fixing member 7 to limit the travel of the movable pressing block assembly 4 .

[0040] like Figure 4 As shown, the positioning support assembly 2 includes a positioning reference plate 21 and a replaceable V-shaped support plate 22 , and the clamping spacing adjustment assembly 6 is fixedly connected to the V-shaped support plate 22 .

[0041] The V-shaped support plate 22 is connected to one of the slider groups 32 on the linear guide assembly, and is driven by the slider group to slide along the guide rail 31. Thus, the positioning support assembly can be moved and adjusted. The V-shaped support plate 22 can be replaced according to the outer diameter length specifications of the cylindrical ceramic green body.

[0042] The V-shaped support plate 22 is configured as a rectangular plate structure, and the universal positioning structure is a plurality of V-shaped positioning grooves 23 provided on the V-shaped support plate 22. Of course, in other embodiments, the universal positioning structure may also be configured in other shapes such as an arc shape.

[0043] The V-shaped positioning groove 23 runs through the width direction of the V-shaped support plate 22, and a plurality of V-shaped positioning grooves 23 are evenly distributed on the V-shaped support plate 22, which are used to support and place cylindrical ceramic green bodies with different outer diameters, and the outer diameter of the cylindrical ceramic green bodies that can be supported is 10 to 40 mm. The material of the V-shaped support plate 22 is preferably carbon steel. An avoidance hole 24 is provided at the bottom or side of the V-shaped positioning groove 23, which is used to avoid the processing tool during the processing, and can facilitate the downward discharge of processing chips without affecting the processing.

[0044] The material of the positioning reference plate 21 is preferably carbon steel. The positioning reference plate 21 is vertically arranged on the outside of the V-shaped support plate 22 to achieve the edge positioning of one end of the cylindrical ceramic green body and to perform table straightening and measurement based on the workpiece.

[0045] The clamping distance adjustment components 6 are provided in two groups, and the two groups of the clamping distance adjustment components are respectively fixed at two ends of the V-shaped support plate 22 .

[0046] The clamping spacing adjustment assembly 6 includes an adjustment slider 61 and a rotating screw 62. The material of the adjustment slider 61 is preferably carbon steel. The adjustment slider 61 can be selectively connected to the threaded connection hole 71 on the adjustment fixing member 7 in an adjustable manner. Thus, the mobile positioning of the positioning support assembly 2 is realized to meet the clamping and positioning needs of cylindrical ceramic green bodies of different specifications and models.

[0047] The adjusting slider 61 is locked on different threaded connection holes 71 of the adjusting fixture 7 by rotating the screw 62, so as to adjust the distance between the positioning reference plate 21 and the movable pressing block assembly 4, so as to clamp products of different lengths.

[0048] like Figure 5 As shown, the movable pressure block assembly 4 includes a pressure block mounting plate 41 for connecting to the slider group 32 on the linear guide rail assembly 3 and sliding along the guide rail 31, a pressure block fixing plate 42 is arranged on the pressure block mounting plate 41 in parallel with the pressure block mounting plate 41, and a plurality of flexible adjustable clamping members 43 are arranged on the pressure block fixing plate 42 corresponding to the number of V-shaped positioning grooves 24.

[0049] like Figure 6 As shown, both ends of the pressing block mounting plate 41 are respectively provided with L-shaped mounting portions 46 , and the L-shaped mounting portions are provided with flexible locking assembly mounting holes 47 . The flexible locking assembly mounting holes 47 are connected to the first connecting block 51 .

[0050] The flexible adjustable pressing member 43 includes a flexible pressing member 44 and an adjusting member 45 that drives the flexible pressing member 44 to adjust and tighten. In this embodiment, the flexible pressing member 44 is a plastic pressing block, and the plastic pressing block is a columnar structure. In other embodiments, the flexible pressing member 44 is a polyester pressing block, and the polyester pressing block is a square or conical structure. It can also be made of other materials and other shapes. In this embodiment, the adjusting member 45 is an adjusting screw.

[0051] One end of the flexible pressing member 44 is arranged opposite to the V-shaped positioning groove, and the other end of the flexible pressing member 44 is connected to the adjusting member 45, and the adjusting member 45 is connected to the pressing block fixing plate 42 in a threaded adjustment manner, and the adjusting end of the adjusting member 45 is arranged on the outside of the pressing block fixing plate 42. The distance that the flexible pressing member 44 extends out of the pressing block fixing plate 42 is adjusted by the adjusting member 45, so as to adjust the locking pressure of a single cylindrical ceramic green body.

[0052] In other embodiments, the flexible pressing member 44 in the flexible adjustable pressing member 43 may adopt an integrated pressing plate structure or an integrated pressing block structure, which can meet the clamping and positioning requirements of cylindrical ceramic green bodies of the same length.

[0053] The flexible locking components 5 are arranged at both ends of the bottom plate 12 .

[0054] like Figure 7 , Figure 8 As shown, the flexible locking assembly 5 includes a first connecting block 51, a second connecting block 52 and a buckle assembly 53. The first connecting block 51 is fixedly connected to the pressing block mounting plate 41 and can drive the movable pressing block assembly 4 to slide along the guide rail 31. The second connecting block 52 is provided with a waist-shaped groove 54, and the second connecting block 52 is adjustably connected to the end of the bottom plate 12 through the waist-shaped hole 54.

[0055] The elastic member 55 is arranged between the first connecting block and the second connecting block. Specifically, a first mounting hole is arranged on the first connecting block, and a second mounting hole is arranged on the second connecting block. One end of the elastic member is arranged in the first mounting hole, and the other end is arranged inside the second mounting hole. The first connecting block 51 and the second connecting block 52 are elastically connected by the elastic member 55. When the flexible locking assembly 5 presses the cylindrical ceramic green body, the elastic force of the elastic member 55 makes the first connecting block 51 and the second connecting block 52 move away from each other, that is, the first connecting block 51 and the second connecting block 52 are stretched apart, so as to achieve the purpose of flexibly clamping the cylindrical ceramic green body. In this embodiment, the elastic member 55 adopts a spring. In other embodiments, the elastic member 55 can adopt an elastic block. The elastic member 55 can also adopt a pneumatic structure.

[0056] By operating the locking and opening of the buckle assembly 53, the movable pressing block assembly 4 is driven to be pressed and loosened, thereby realizing the function of batch pressing of cylindrical ceramic green bodies. During the locking process of the buckle assembly, the first connecting block will move toward the second connecting block and compress the elastic member to achieve locking. After locking, the elastic member is compressed, and the elastic force of the elastic member causes the first connecting block to move away from the second connecting block, thereby causing the movable pressing block assembly to also move away from the cylindrical ceramic green body, providing a reverse offset force for the pressing force, realizing flexible pressing of the flexible locking assembly, reducing the risk of clamping cracks, and improving the processing efficiency and quality of the product.

[0057] like Fig. 9 As shown, the method for batch processing cylindrical ceramic green bodies by using the cylindrical ceramic green body batch clamping fixture comprises the following steps: Step 1: Adjust the position of the positioning support assembly according to the specifications of the cylindrical ceramic green body to be processed, specifically by adjusting the slider to select the required threaded connection hole on the adjustment fixing member 7 for connection.

[0058] Step 2: Place the cylindrical ceramic green bodies to be processed in batches in sequence into the V-shaped positioning grooves of the V-shaped support plate.

[0059] Step 3: Adjust the elastic force of the elastic member compression through the flexible locking assembly, thereby adjusting the size of the flexible locking clamping force. Specifically, this is achieved by adjusting the relative fixed position of the waist-shaped groove on the second connecting block and the end of the bottom plate. When the second connecting block moves toward the side of the positioning support assembly, the compression elastic force of the spring increases, and when the second connecting block moves toward the side of the movable pressure block assembly, the compression spring force of the spring decreases.

[0060] Step 4: Lock the buckle assembly and press all the cylindrical ceramic green bodies to be processed through the movable pressing block assembly to achieve batch pressing.

[0061] Specifically, the buckle components at both ends are operated. During the locking process, the first connection block in the buckle component moves toward the second connection block and squeezes the elastic member, and at the same time drives the movable pressing block component to approach the cylindrical ceramic green body to be processed along the guide rail and presses it through the flexible pressing member. After locking, due to the elastic force of the elastic member, the first connection block and the second connection block are separated and stretched outward by the elastic force, so that a flexible clamp is formed between the movable pressing block component and the cylindrical ceramic green body to be processed. The cylindrical ceramic green bodies are clamped in batches on the clamping fixture.

[0062] Step 5: The locking pressure of the single cylindrical ceramic green body to be processed is adjusted by the adjusting member so that the flexible pressing member can provide the most appropriate locking pressure.

[0063] Step 6: Use the positioning reference plate on the clamping fixture in the machining center to measure the center of a single cylindrical ceramic green body.

[0064] Step 7: Set the processing program. According to the product spacing, array process the cylindrical ceramic green bodies on the clamping fixture to realize the functions of batch clamping, one-time measurement, and batch processing. The processing accuracy is high and the operation is convenient, fast and efficient.

[0065] In this embodiment, the radial center holes of cylindrical ceramic green bodies with different diameters and lengths are respectively processed as an example for description.

[0066] The cylindrical ceramic green bodies to be processed include cylindrical ceramic green bodies 100, which have an outer diameter of 20 mm and a length of 30 mm; cylindrical ceramic green bodies 200, which have an outer diameter of 40 mm and a length of 60 mm; and cylindrical ceramic green bodies 300, which have an outer diameter of 10 mm and a length of 70 mm.

[0067] The method for batch processing radial center holes 400 of cylindrical ceramic green bodies with different outer diameters and different lengths by using the cylindrical ceramic green body batch clamping fixture comprises the following steps: Step 1: Adjust the position of the positioning support assembly according to the specifications of the cylindrical ceramic green body 3 to be processed.

[0068] Step 2: Place the first cylindrical ceramic green body to be processed, the second cylindrical ceramic green body, and the third cylindrical ceramic green body in groups side by side and in sequence into the V-shaped positioning groove of the V-shaped support plate.

[0069] Step 3: Adjust the elastic force of the elastic member compression through the flexible locking assembly, thereby adjusting the size of the flexible locking clamping force. Specifically, this is achieved by adjusting the relative fixed position of the waist-shaped groove on the second connecting block and the end of the bottom plate. When the second connecting block moves toward the side of the positioning support assembly, the compression elastic force of the spring increases, and when the second connecting block moves toward the side of the movable pressure block assembly, the compression spring force of the spring decreases.

[0070] Step 4: Lock the buckle assembly, and press the cylindrical ceramic green body to be processed three through the movable pressing block assembly to achieve batch pressing.

[0071] Specifically, the buckle components at both ends are operated. During the locking process, the first connection block in the buckle component moves toward the second connection block and squeezes the elastic member, and at the same time drives the movable pressing block component to approach the cylindrical ceramic green body to be processed along the guide rail and presses it through the flexible pressing member. After locking, due to the elastic force of the elastic member, the first connection block and the second connection block are separated and stretched outward by the elastic force, so that a flexible clamp is formed between the movable pressing block component and the cylindrical ceramic green body to be processed. The cylindrical ceramic green bodies are clamped in batches on the clamping fixture.

[0072] Step 5: The locking pressure of the single cylindrical ceramic green body 1 and the cylindrical ceramic green body 2 to be processed is adjusted by the adjusting piece, so that the flexible pressing piece can provide the most appropriate locking pressure and realize the locking of all the cylindrical ceramic green bodies to be processed.

[0073] Step 6: Use the positioning reference plate on the clamping fixture to measure the center of a single cylindrical ceramic green body in the machining center. Specifically, measure the center of the outermost cylindrical ceramic green body.

[0074] Step 7: Set the processing program. According to the product spacing, array process the radial center holes on the cylindrical ceramic green body 1, cylindrical ceramic green body 2, and cylindrical ceramic green body 3 on the clamping fixture to realize the functions of batch clamping, one-time measurement, and batch processing. The processing accuracy is high and the operation is convenient, fast and efficient.

[0075] The cylindrical ceramic green body batch clamping jig includes a clamping spacing adjustment component 6 with adjustable clamping spacing and a flexible locking component for flexible clamping, which can effectively solve the problem of ceramic green bodies being prone to cracking during the clamping process, and is universal for products of various sizes and specifications. The product has strong versatility and can realize batch clamping, positioning and processing of products. It can be used for batch processing of different features such as radial holes and waist grooves of cylindrical ceramic green bodies, and has strong applicability and flexibility. Cylindrical ceramic green bodies with the same outer diameter and the same length can be placed at the same time, and cylindrical ceramic green bodies with different outer diameters and different lengths can also be placed. It can also be placed cylindrical ceramic green bodies with the same outer diameter and different lengths, and it can also be placed cylindrical ceramic green bodies with different outer diameters and the same length. It can be placed specifically according to processing needs.
