Description

Technical Field

[0001] The utility model relates to the technical field of groove and tenon processing of spliced ​​plates, and in particular to a groove and tenon processing tool for carbon-carbon spliced ​​plates. Background Art

[0002] As an emerging material for single crystal thermal field, carbon / carbon composite materials have gradually replaced graphite materials to become the dominant material for thermal insulation of single crystal thermal field. The preparation of carbon / carbon composite materials is a highly complex process, including high-temperature conversion and multiple steps, and the power loss used in the preparation of carbon / carbon composite materials is also huge. In order to reduce costs and increase efficiency, the overall process is changed to a split splicing process, which increases the internal space utilization rate of the densification equipment. The same power consumption can produce more densified products and they are not easy to deform. The splicing process is to assemble the arc-shaped splicing pieces into a whole using a mortise and tenon structure. However, since the splicing process is a brand new runway, the processing of the most stringent grooves and tenons in the splicing process has always been a headache.

[0003] The precision of the processing technology of the groove and tenon in the splicing process is the key factor to determine whether a splicing product can pass. The existing processing methods have many disadvantages in the process of processing the groove and tenon of the splicing piece. First, the processing efficiency is low. Because the splicing piece is in the shape of an arc, the machine clamping and alignment are too slow, and the processing allowance of the groove and tenon cannot be guaranteed. Leaving too much allowance in the blank will increase the cost of raw materials and processing costs. Second, the qualified rate is low. The traditional processing method cannot meet the current accuracy of the groove and tenon. The reason for the failure of most splicing pieces is that the splicing gap is large or the size after splicing is larger than the qualified size. The fundamental reason for this problem is that the splicing piece is trapezoidal or parallelogram, and the width of the groove and tenon is unstable and the position is inconsistent, resulting in low strength after splicing and unsatisfactory insulation effect.

[0027] Embodiment 1:

[0028] like Figures 1 to 4 As shown, a tool for processing the groove and tenon of carbon-carbon spliced ​​plates includes a tooling table 1, which is vertically installed on a workbench. An arc plate 2 is arranged on the top of the tooling table 1. The curvature of the arc plate 2 is the same as the curvature of a blank 3. A limiting component and a clamping component are arranged on the surrounding side of the tooling table 1. The blank 3 is limited by the limiting component and fits tightly with the arc plate 2. The clamping component fixes the blank 3 for subsequent processing.

[0029] The tooling table 1 is fixed to the workbench, and the blank 3 is placed on the curved plate 2 on the top of the tooling table 1. The curved plate 2 has the same curvature as the blank 3 and fits tightly with the blank 3 to provide a more stable support. The blank 3 is limited in the front and rear directions and the left and right directions by the limiting component, so that the position of the blank 3 on the tooling table 1 corresponds to the processing position of the equipment, and sufficient processing allowance is left. Then, the blank 3 after limiting is fixed on the tooling table 1 by the clamping component to facilitate subsequent processing. The tooling table 1 in the present application has a simple structure and is convenient for quickly clamping the blank 3, thereby improving the processing efficiency.

[0030] Specifically, a matching carbon steel tooling table 1 is set according to the inner diameter of the insulation cylinder of different specifications, the size of the tooling table 1 is matched with the spacing of the worktable rails of the milling machine processing equipment, the tooling table 1 is adjusted to be completely parallel to the Z axis of the equipment, and the position of the tooling table 1 is fixed so that the tooling and the worktable form a whole.

[0031] In the mortise and tenon processing tooling of the carbon-carbon spliced ​​plate of the present embodiment, the tooling table 1 includes a right side plate 4, the top of the right side plate 4 is fixedly connected to the arc plate 2, and the upper edge of the right side plate 4 is flush with the arc plate 2, and the clamping assembly is detachably connected to the right side plate 4. Specifically, the clamping assembly includes a base and a clamp 10, and the clamp 10 is detachably mounted on the right side plate 4 through the base, and a base mounting hole is opened on the right side plate 4.

[0032] Through the above arrangement, the right side plate 4 is prevented from protruding from the arc plate 2, thereby ensuring that the blank 3 is closely fitted with the arc plate 2, and at the same time, it is convenient for the clamp 10 to press down and compact the blank 3. The clamp 10 uses a quick clamp in the prior art, which is installed through the base mounting hole, is easy to disassemble, simple to operate, and convenient to compact and fix the blank 3. Preferably, 1-2 quick clamps are selected and installed according to the size of the blank 3.

[0033] In the mortise and tenon processing tooling of the carbon-carbon splicing plate of the present embodiment, the tooling table 1 includes a left side plate 5, the arc plate 2 is fixedly installed between the left side plate 5 and the right side plate 4, the limiting assembly includes a first limiting assembly, the first limiting assembly is arranged on the left side plate 5, the first limiting assembly limits the left and right directions of the blank 3, specifically, the first limiting assembly includes a limiting plate 6, the limiting plate 6 is arranged perpendicular to the left side plate 5 to form a slot for accommodating the blank 3, the limiting plate 6 is arc-shaped and the curvature is consistent with the curvature of the blank 3, the height of the slot is greater than the height of the blank 3, and the blank 3 is clamped in the slot.

[0034] A slot is formed between the limit plate 6 and the arc plate 2, and the blank 3 is inserted into the slot. The left end face of the blank 3 fits with the left side plate 5, and the upper and lower surfaces of the blank 3 fit with the arc-shaped limit plate 6 and the arc-shaped arc plate 2 respectively, thereby achieving alignment and limiting the left and right directions of the blank 3 to avoid the blank 3 being skewed, resulting in inaccurate position of the machined groove, affecting normal use.

[0035] Preferably, a gap of 15 mm is left between the limiting plate 6 and the arc-shaped plate 2 to facilitate the blank 3 to be embedded in the slot.

[0036] In the mortise and tenon processing tooling of the carbon-carbon spliced ​​plate of the present embodiment, the tooling table 1 also includes a front side plate 7 and a rear side plate 8, and the front side plate 7 and the rear side plate 8 are arranged opposite to each other, and the bottoms of the front side plate 7 and the rear side plate 8 are respectively bent to form positioning parts, and the positioning parts are arranged in contact with the workbench, and positioning holes are respectively opened on the positioning parts, and the tooling table 1 is fixed to the workbench through the positioning holes.

[0037] Specifically, the front side plate 7 and the rear side plate 8 are connected to the right side plate 4 and the left side plate 5 from the front and rear sides respectively, and the tooling table 1 is fixed on the workbench as a whole through fasteners and positioning holes.

[0038] In the groove and tenon processing tooling of the carbon-carbon spliced ​​plate of this embodiment, the limiting assembly includes a second limiting assembly, and the second limiting assembly includes a mounting rod, and the mounting rod is installed perpendicular to the front side plate 7. The mounting rod is rotatably connected to the limiting rod 8, and the limiting rod 8 limits the front and rear directions of the blank 3.

[0039] Specifically, the length of the limiting rod 8 is greater than the distance between the mounting rod and the arc plate 2. The limiting rod 8 is rotated to make the limiting rod 8 face vertically upward. After the blank 3 is inserted into the slot, the blank 3 is pushed to slide in the slot until the front end of the blank 3 abuts against the limiting rod 8, thereby achieving the limiting and alignment of the front and rear directions of the blank 3, so that the blank 3 is convenient for subsequent processing by the milling machine. Preferably, two sets of the second limiting assembly are provided, so that the front end of the blank 3 is evenly stressed and the limiting and alignment effect is better.

[0040] Preferably, the tooling in this embodiment is used for groove processing. When the blank 3 is clamped by the above tooling, after the product is inserted into the slot on the left side plate 5, it is leveled against the two limit rods 8 on the front side plate 7, and then pressed by the clamping assembly to make the blank 3 fit tightly on the arc-shaped tooling table 1, and the limit rods 8 on the front side plate 7 are rotated to loosen the limit assembly and fall. Start the CNC milling machine to process the reference surface to ensure that the groove is milled after seeing the light.

[0041] Embodiment 2:

[0042] like Figures 5 to 8 As shown, in the mortise and tenon processing tooling of the carbon-carbon spliced ​​plate of the present embodiment, the structure of Example 1 is used, except for the following settings: the limiting component includes a second limiting component, the second limiting component is arranged at one end of the arc plate 2 close to the rear side plate 8, the second limiting component includes a positioning plate 9, the positioning plate 9 is located above the arc plate 2, and a positioning groove for accommodating the blank 3 is formed between the positioning plate 9 and the arc plate 2, the curvature of the positioning groove is the same as the curvature of the blank 3, and the distance between the positioning groove and the end face of the arc plate 2 close to the front side plate 7 is less than the length of the blank 3.

[0043] A positioning groove is formed between the positioning plate 9 and the arc plate 2, and the blank 3 is inserted into the positioning groove to achieve upper positioning of the blank 3 in the front-to-back direction. The installation position of the positioning plate 9 on the arc plate 2 is determined according to the processing allowance required for the blank 3, so that the blank 3 is effectively limited while leaving enough processing allowance for processing.

[0044] Specifically, Figure 6 As shown, the limiting plate 6 on the left side plate 5 is provided with a notch at one end close to the rear side plate 8 to prevent the limiting plate 6 from interfering with the positioning plate 9 .

[0045] Preferably, there are several positioning plates 9, and the positioning plates 9 are equidistantly arranged on the arc plate 2. A plurality of positioning plates 9 are arranged, and a notch is left between two adjacent positioning plates 9, so as to facilitate adjusting the position of the blank 3 on the arc plate 2 from the notch.

[0046] Preferably, after the groove is processed by the tooling in Example 1, the tooling in this embodiment is used to process the tenon.

[0047] This application solves the problem of low processing efficiency and low qualified rate of splicing slots and tenons by cooperating with two sets of tooling. The reference surface of this process tooling relies on the surface processed in the previous process as the reference surface and reference point, and the processed size is stable. When processing a circular insulation cylinder made of 8 carbon / carbon inserts, carbon / carbon inserts with different surpluses can be processed in different categories, and each surface splicing point has a separate size control, which effectively avoids insufficient processing surplus of important dimensions and inability to splice; it reduces the trapezoids, parallelograms and finished products that are too large or too small after multiple processing that often occur in such products.

[0048] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "rotation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, for ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0049] Although the embodiments of the present invention have been shown and described in detail, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
