Simultaneously, the support can support the inner arc surface of the fan-shaped product, effectively preventing product damage caused by concentrated stress points during grinding due to excessive span. Furthermore, the angle block design can adapt to the angle differences of different products, and the locking element locks and fixes the angle, further improving the applicability and clamping stability of the equipment.

Description

Technical Field

[0001] This utility model relates to the field of product inner and outer arc processing technology, specifically a fixture for processing the inner and outer arcs of fan-shaped products. Background Technology

[0002] Tile-shaped products are typically initially processed using fast wire EDM. While this method is fast, it often leaves noticeable molybdenum wire marks on the machined surface, resulting in poor surface roughness and affecting the accuracy of the product's curvature, making it unsuitable for direct use. Therefore, specific grinding wheels are needed to perform secondary processing and correction on the curved surfaces of these products to improve their precision and surface quality.

[0003] However, tile-shaped products come in various specifications, differing not only in size and angle, but even the same product may have different angle requirements. During secondary processing, each specification of product requires specially designed tooling to fix and precision-machine its curvature. This not only increases the cost of tooling materials and processing time, but also, due to the different angles of different products, the tooling that has already been made cannot be reused, resulting in a waste of resources. Therefore, a fixture for machining the inner and outer arcs of fan-shaped products is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture for machining the inner and outer arcs of fan-shaped products, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixture for machining the inner and outer arcs of a fan-shaped product, comprising:

[0006] A base on which a support is mounted;

[0007] Two symmetrically arranged mounting bases, both of which are slidably connected to the upper surface of the base; and

[0008] An angle block is rotatably connected to the mounting base. The mounting base is provided with a locking component to lock the angle block. When clamping the product, the angle block is adjusted to an angle that matches the side wall of the product, and then the locking component is rotated to fix the angle of the angle block.

[0009] As a further embodiment of this utility model: a positioning groove is provided in the middle area of ​​the upper surface of the base, and a first waist-shaped hole is provided on the side wall opposite to the positioning groove, and the first waist-shaped hole connects the positioning groove and the outside of the base.

[0010] As a further embodiment of this utility model: the bracket is set in the positioning groove, and the bracket is provided with a threaded hole. When the bracket is placed in the positioning groove, the position of its threaded hole coincides with the first waist-shaped hole.

[0011] As a further embodiment of this utility model: the mounting base includes a fixed base, and two side plates are fixed to both sides of the fixed base by bolts. The opposing sides of the two side plates are each equipped with a rotating shaft connected to the angle block.

[0012] As a further embodiment of this utility model: the locking member is installed on the side plate, and the end of the locking member passes through the side plate and maintains contact with the angle block.

[0013] As a further embodiment of this utility model: two guide grooves are formed on the upper surface of the base along its length, and both guide grooves are T-shaped. A T-shaped locking block adapted to the guide groove is installed in the guide groove, and the end of the T-shaped locking block is rotatably connected to a second threaded rod that extends from the lower surface of the fixed base to the upper surface.

[0027] 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.

[0028] Please see Figure 1-7 In this embodiment of the utility model, a fixture for machining the inner and outer arcs of a fan-shaped product includes:

[0029] Base 1, on which a support 2 is mounted;

[0030] Two symmetrically arranged mounting bases 3, both of which are slidably connected to the upper surface of the base 1; and

[0031] Angle block 4 is rotatably connected to mounting base 3. Mounting base 3 is provided with locking member 5 for locking angle block 4. When clamping the product, after adjusting angle block 4 to an angle that matches the side wall of the product, rotating locking member 5 completes the fixation of angle block 4 angle.

[0032] Specifically, the bracket 2 is mounted on the base 1, and its height is adjustable. The upper surface of the bracket 2 has a downwardly recessed groove, which effectively restricts the fan-shaped arc of the product, ensuring the product is stably placed on the bracket 2. This facilitates the clamping of the product by the angle blocks 4 on both sides. When the arc span of the product is large, the distance between the two mounting seats 3 on the base 1 is adjusted to match the product. Subsequently, the tilt angle of the angle blocks 4 is adjusted according to the angle of the two side walls of the product relative to the vertical plane. The angle blocks 4 are equipped with angle scales, and the mounting seats 3 have small windows 17 for observing the rotation angle of the angle blocks 4. This allows for precise adjustment of the angle block 4 to match the angle of the product's side walls, achieving stable clamping of the product and facilitating subsequent processing. After the angle block 4 is adjusted, the locking member 5 is rotated to apply pressure to the end face of the angle block 4, thus fixing the angle block 4 after its position adjustment.

[0033] Through the above technical solution, the sliding connection between the two mounting bases 3 and the base 1 can adapt to a large range of arc spans. The angle block 4 is used to accurately position the fan-shaped products with different arcs. After positioning, the angle block 4 at different angles is locked by the locking part 5 to ensure the stability and ease of operation of the product in the subsequent processing. With the cooperation of the above components, it can adapt to the different angle differences of various products.

[0034] Please see Figure 4 and Figure 8 In one embodiment, preferably, a positioning groove 6 is formed in the middle area of ​​the upper surface of the base 1, and a first oblong hole 7 is formed on the side wall opposite to the positioning groove 6, and the first oblong hole 7 connects the positioning groove 6 and the outside of the base 1. The bracket 2 is disposed in the positioning groove 6, and a threaded hole 8 is formed on the bracket 2. When the bracket 2 is placed in the positioning groove 6, the position of its threaded hole 8 coincides with the first oblong hole 7. A first threaded rod 9 is provided on the base 1, with one end passing through the first oblong hole 7 and connecting to the threaded hole 8. Furthermore, the bracket 2 is adapted to the interior of the positioning groove 6, allowing the bracket 2 to be placed inside the positioning groove 6. There are two first oblong holes 7, which are set in the vertical direction and their width is adapted to the first threaded rod 9, making it easy for the first threaded rod 9 to pass through. The design of the first oblong holes 7 not only limits the height adjustment range of the bracket 2, but also prevents the bracket 2 from falling out of the positioning groove 6 during the adjustment process. When the height of the bracket 2 is adjusted to the correct position, the first threaded rod 9 is rotated so that one end of it fits tightly against the surface of the base 1, thereby fixing the height of the bracket 2.

[0035] Please see Figure 2-3In one embodiment, preferably, the mounting base 3 includes a fixed base 301. Two side plates 302 are fixed to both sides of the fixed base 301 by bolts 303. The opposite sides of the two side plates 302 are each equipped with a rotating shaft connected to the angle block 4. The locking member 5 is installed on the side plate 302, and the end of the locking member 5 passes through the side plate 302 and keeps in contact with the angle block 4. Furthermore, the angle block 4 is connected to the side plate 302 by the rotating shaft. The rotating shaft and the side plate 302 can be rotatably connected, or the rotating shaft and the angle block 4 can be rotatably connected. This allows the angle block 4 to move in a circular motion along the rotating shaft while supporting the angle block 4. The locking member 5 is a bolt. By rotating the bolt, its end applies pressure to the end of the angle block 4, thereby fixing the angle of the angle block 4.

[0036] Please see Figure 1-3 and Figure 8 In one embodiment, preferably, two guide grooves 10 are formed on the upper surface of the base 1 along its length, and both guide grooves 10 are T-shaped. A T-shaped locking block 11 adapted to the guide groove 10 is installed in the guide groove 10. The end of the T-shaped locking block 11 is rotatably connected to a second threaded rod 12 that extends from the lower surface of the fixed seat 301 to the upper surface. Furthermore, the guide groove 10 provides a moving path for the fixed seat 301, ensuring that no positional shift occurs when adjusting the distance between the two fixed seats 301. The T-shaped structure design of the guide groove 10 can prevent the fixed seat 301 from detaching from the guide groove 10 in the vertical direction. Through the cooperation of the second threaded rod 12 and the T-shaped locking block 11, rotating the second threaded rod 12 can move the T-shaped locking block 11 upward and press it against the inner wall of the guide groove 10, thereby locking the position of the fixed seat 301 on the upper surface of the base 1 and effectively fixing the distance between the two fixed seats 301.

[0037] Please see Figure 1-2 and Figure 8In one embodiment, preferably, it further includes two baffles 13, which are disposed on the surface of the base 1. Each baffle 13 has a second oblong hole 14. Each baffle 13 has a third threaded rod 15 that passes through the second oblong hole 14 and connects to the base 1. One of the baffles 13 is equipped with a fourth threaded rod 16. Furthermore, both baffles 13 are fixed to the base 1 by the third threaded rod 15, and the two baffles 13 are arranged in parallel. The inner diameter of the second oblong hole 14 is adapted to the third threaded rod 15, facilitating the fixing of the end of the third threaded rod 15 after passing through the second oblong hole 14. The positions of plate 13 and base 1 are such that when the unthreaded end of the third threaded rod 15 is not in contact with the surface of the baffle 13, the height of the baffle 13 relative to the base 1 can be adjusted. When the unthreaded end of the third threaded rod 15 is in contact with the surface of the baffle 13, the height of the baffle 13 is fixed by continuously rotating the unthreaded end of the third threaded rod 15 to apply pressure to the baffle 13. In addition, rotating the fourth threaded rod 16 on the baffle 13 causes one end of the fourth threaded rod 16 to press against the end face of the fan-shaped product, and the fan-shaped product is clamped and fixed by the fourth threaded rod 16 and another baffle 13, which can prevent the product from flying out due to excessive cutting force.

[0038] Working principle and usage process of this utility model:

[0039] The product's angle can be determined from the product drawings. Rotate the angle blocks 4 at both ends and observe the angle values ​​through the small window 17 to obtain the corresponding angle of the product. Then, rotate the bolts to fix the position of the angle blocks 4. Move the mounting seat 3 on the base 1 until the fan-shaped product can be placed in the angle between the two angle blocks 4 without any gap. This will lock the angle of the product. When the grinding allowance of the product is too large, the side baffle 13 can be raised to a position slightly lower than the machined surface of the product and then locked. This can prevent the product from flying out due to excessive cutting force. When the span of the product is large and the suspended size is too large, the bracket 2 built into the base 1 can be raised, supporting the inner arc surface of the fan-shaped product and then locking the bracket 2. This will solve the problem of product damage caused by the concentration of stress points during grinding due to the large span of the fan-shaped product.

[0040] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
