Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixed tooling technology, and in particular to a fixed tooling for cutting risers of aluminum alloy caliper castings. Background Technology
[0002] In the automotive parts manufacturing industry, aluminum alloy caliper castings, as a braking system component, are widely used due to their lightweight, high strength, and good heat dissipation performance. These castings are usually formed through casting processes. During production, risers are often designed and used to ensure casting quality. As an additional part attached to the top or side of the caliper casting, the riser's main function is to provide extra molten metal to the casting during the casting process to compensate for the volume reduction caused by shrinkage during the solidification stage, thereby preventing defects such as shrinkage cavities and porosity. Usually, risers are placed at the highest and thickest points of the casting to achieve natural feeding by the gravity of the molten metal, ensuring the compactness of the casting structure. The riser is a structure specially added during the casting process to avoid casting defects. After the casting is formed, it becomes a redundant part and needs to be removed in subsequent processes. After removing the riser, the surface of the caliper casting is smoothed, which not only improves the appearance quality of the casting but also creates favorable conditions for subsequent machining and surface treatment.
[0003] In the current process of removing risers from caliper-type castings, the casting needs to be fixed on a special fixture, and the riser on the casting needs to be cut off using a cutting machine. However, the existing special fixtures have problems with cumbersome operation procedures and low clamping efficiency when clamping caliper-type castings. This situation leads to limitations in the existing tooling when fixing this type of casting. There is a lack of simple fixing tooling in the current technology that can achieve quick positioning and clamping.
[0004] To address the aforementioned issues, this application proposes a fixing fixture for cutting risers in aluminum alloy caliper castings. Utility Model Content
[0005] Based on the technical problems existing in the background art, this utility model proposes a fixing tool for cutting the riser of aluminum alloy caliper castings.
[0006] This utility model proposes a fixing fixture for cutting the riser of an aluminum alloy caliper casting, which includes a fixture plate, a riser limiting member, a limiting part and a second T-shaped protrusion;
[0007] The limiting part, the riser limiting member and the second T-shaped protrusion are fixed to the side of the tooling plate in sequence, and a clamping workpiece is clamped on the limiting part, the riser limiting member and the second T-shaped protrusion.
[0008] The caliper workpiece includes a riser body, a first caliper body, and a second caliper body. The riser body is limited on a riser limiting member. The side and bottom of the riser body are integrally connected to an end shaft. The first caliper body is integrally connected to the end shaft on the side and is clamped on the limiting part. The second caliper body is integrally connected to the end shaft on the bottom and is clamped on the second T-shaped protrusion.
[0009] The tooling plate has a cutting opening in the middle, and the connection between the first caliper body and the side end shaft is located in front of the cutting opening.
[0010] Preferably, the riser limiting component includes a disc, a first U-shaped block, and a second U-shaped block. The disc, the first U-shaped block, and the second U-shaped block are all fixed to the middle of the side of the tooling plate. The first U-shaped block is located on one side of the disc, and the second U-shaped block is located at the bottom of the disc. A conical protrusion is fixed on the front side of the disc. A slot is integrally formed in the riser body. The conical protrusion is inserted into the slot, and the riser body abuts against the surface of the disc. The end shafts on the side and bottom of the riser body are respectively engaged on the first U-shaped block and the second U-shaped block.
[0011] Preferably, the tooling plate has two positioning holes arranged around the disk on its side, and two riser rods are integrally connected to the riser body, with the two riser rods respectively inserted into the two positioning holes.
[0012] Preferably, the limiting part includes a first T-shaped protrusion and a limiting block. The first T-shaped protrusion is fixed to the side of the tooling plate and is located on the side of the first U-shaped block away from the disk. The limiting block is fixed to one side of the first T-shaped protrusion. The first caliper body is clamped on the first T-shaped protrusion and abuts against the limiting block. The second T-shaped protrusion is located below the second U-shaped block.
[0013] Preferably, the tooling plate has a chip extraction cavity, and the inner walls on both sides of the cutting opening have multiple chip extraction holes communicating with the chip extraction cavity. The end of the tooling plate is detachably connected to a chip extraction pipe, which is used to connect to a chip extraction pump.
[0014] Preferably, the end of the tooling plate is connected to a connector that communicates with the chip extraction chamber, and one end of the chip extraction tube is connected to a plug that is inserted into the connector.
[0015] The above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0016] 1. This design achieves rapid clamping of caliper workpieces through the coordinated positioning and support of a conical protrusion, a first U-shaped block, a second U-shaped block, a positioning hole, a limiting part, and a second T-shaped protrusion. During operation, the riser body is fitted onto the conical protrusion, and its side end shaft and bottom end shaft are respectively clamped onto the first U-shaped block and the second U-shaped block. The riser rod is inserted into the positioning hole, and the first caliper body and the second caliper body are respectively clamped onto the limiting part and the second T-shaped protrusion, completing the assembly quickly. During cutting, the circular cutter of the cutting machine enters the cutting opening, first cutting the connection between the side end shaft of the riser body and the first caliper body, and then changing the direction of the second caliper body to cut its connection with the end shaft, thereby removing the riser body and obtaining the complete first caliper body and the second caliper body. This design simplifies the operation process, improves clamping efficiency, solves the problem of cumbersome clamping of existing fixtures, and facilitates the cutting and removal of the riser body.
[0017] 2. When cutting the connection between the riser body and the first and second clamp bodies, the chip extraction pipe on the tooling plate can be connected to a chip extraction pump. The chip extraction pump generates negative pressure in the chip extraction chamber inside the tooling plate. The waste chips during cutting are sucked into the chip extraction chamber through the chip extraction holes opened on both sides of the cutting opening, and then extracted into the chip extraction pump through the chip extraction pipe. The above design realizes the real-time suction and removal of waste chips during the cutting process, effectively maintaining the cleanliness of the working area and improving the functionality of this fixed tooling.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0025] Example 1
[0026] like Figure 1-5 As shown, the present invention proposes a fixing fixture for cutting the riser of an aluminum alloy caliper casting, including a fixture plate 1, a riser limiting member 2, a limiting part 3 and a second T-shaped protrusion 4;
[0027] The limiting part 3, the riser limiting part 2 and the second T-shaped protrusion 4 are fixed to the side of the tooling plate 1 in sequence, and the clamp workpiece 6 is loaded on the limiting part 3, the riser limiting part 2 and the second T-shaped protrusion 4.
[0028] The caliper workpiece 6 includes a riser body 61, a first caliper body 62 and a second caliper body 63. The riser body 61 is limited on the riser limiting member 2. The side and bottom of the riser body 61 are integrally connected to the end shaft 611. The first caliper body 62 is integrally connected to the end shaft 611 on the side and is clamped on the limiting part 3. The second caliper body 63 is integrally connected to the end shaft 611 at the bottom and is clamped on the second T-shaped protrusion 4.
[0029] A cutting opening is provided in the middle of the tooling plate 1, and the connection between the first caliper body 62 and the side end shaft 611 is located in front of the cutting opening.
[0030] Before cutting the riser in the aluminum alloy caliper casting, the riser limiter 2 is used to initially limit the riser body 61 to prevent it from shifting during subsequent clamping. Then, the first caliper body 62 is engaged and supported by the limiter 3, and the second T-shaped protrusion 4 is engaged and supported by the second caliper body 63, thus completing the clamping of the caliper workpiece 6. The cutting opening in the middle of the tooling plate 1 is aligned with the connection between the first caliper body 62 and the side end shaft 611. Then, the circular cutter of the cutting machine is gradually moved into the cutting opening in the middle of the tooling plate 1 to connect the riser body 61 and the side end shaft 611. Cut the connection between the first clamp body 62 and the second clamp body 63 at the bottom of the riser body 61. After cutting, reverse the direction of the second clamp body 63 and place it on the limiting part 3. Following the above steps, make the circular blade of the cutting knife cut the connection between the second clamp body 63 and the end shaft 611 to obtain the complete first clamp body 62 and second clamp body 63, thus completing the removal of the riser body 61. The above design achieves quick clamping of the clamp workpiece 6 without complicated adjustment through modular positioning, which facilitates the quick cutting of the riser body 61 on it.
[0031] In a specific embodiment, the riser limiting member 2 includes a disc 21, a first U-shaped block 22 and a second U-shaped block 23. The disc 21, the first U-shaped block 22 and the second U-shaped block 23 are all fixed in the middle of the side of the tooling plate 1. The first U-shaped block 22 is located on one side of the disc 21 and the second U-shaped block 23 is located at the bottom of the disc 21. A conical protrusion 211 is fixed on the front side of the disc 21. A slot is integrally formed inside the riser body 61. The conical protrusion 211 is inserted into the slot and the riser body 61 abuts against the surface of the disc 21. The end shafts 611 on the side and bottom of the riser body 61 are respectively locked on the first U-shaped block 22 and the second U-shaped block 23.
[0032] When limiting the riser body 61, the slot on the riser body 61 is aligned with the conical protrusion 211 on the front side of the disc 21 and inserted. The conical surface of the conical protrusion 211 can quickly guide and complete the docking of the riser body 61 and the disc 21. At the same time, the conical structure can form a radial limit on the riser body 61 to prevent it from rotating or shifting in the horizontal direction. After the riser body 61 abuts against the surface of the disc 21, the end shaft 611 on its side and bottom can be respectively inserted into the U-shaped groove of the first U-shaped block 22 and the second U-shaped block 23. The structure of the U-shaped groove can form a double limit on the end shaft 611 in both vertical and horizontal directions to prevent the end shaft 611 from shifting during the cutting process. This structure achieves rapid limiting of the riser body 61 through the combination of conical positioning and U-shaped groove engagement. Compared with the multi-step locking of traditional clamps, this limiting method does not require additional locking operations, shortening the clamping time.
[0033] In a specific embodiment, the tooling plate 1 has two positioning holes 102 arranged around the disk 21 on its side. Two riser rods 612 are integrally connected to the riser body 61, and the two riser rods 612 are respectively inserted into the two positioning holes 102. During the process of fitting the riser body 61 onto the conical protrusion 211, the two riser rods 612 on the riser body 61 are inserted into the positioning holes 102 on the side of the tooling plate 1. The cooperation between the positioning holes 102 and the riser rods 612 can form a positioning constraint on it, further restricting the circumferential rotation and axial displacement of the riser body 61. This structure is equivalent to adding double positioning anchor points on the basis of the original limit position. Even if it is subjected to vibration and impact from the cutting machine during the cutting process, it can maintain a stable position and avoid cutting deviation caused by the slight movement of the workpiece.
[0034] In a specific embodiment, the limiting part 3 includes a first T-shaped protrusion 31 and a limiting block 32. The first T-shaped protrusion 31 is fixed to the side of the tooling plate 1, and the first T-shaped protrusion 31 is located on the side of the first U-shaped block 22 away from the disk 21. The limiting block 32 is fixed to the side of the first T-shaped protrusion 31. The first clamp body 62 is clamped on the first T-shaped protrusion 31 and abuts against the limiting block 32. The second T-shaped protrusion 4 is located below the second U-shaped block 23. When positioning the first clamp body 62... The first clamp body 62 is placed on the first T-shaped protrusion 31. The T-shaped protrusion provides vertical support and lateral limit for the first clamp body 62, preventing it from sinking or shifting to the left or right during cutting. At the same time, the side of the first clamp body 62 abuts against the limiting block 32, which restricts the axial displacement of the first clamp body 62, ensuring that the connection between it and the side end shaft 611 is always aligned with the cutting opening of the tooling plate 1. For the second clamp body 63, vertical and lateral limits are achieved through the second T-shaped protrusion 4.
[0035] Example 2
[0036] When cutting a workpiece, a large amount of waste chips are generated. In order to keep the working area clean, this device has a chip extraction chamber in the tooling plate 1, and a chip extraction pipe 5 is connected to the tooling plate 1, as detailed below:
[0037] In a specific embodiment, a chip extraction chamber is provided inside the tooling plate 1, and multiple chip extraction holes 101 communicating with the chip extraction chamber are provided on both sides of the inner wall of the cutting opening. A chip extraction pipe 5 is detachably connected to the end of the tooling plate 1, and the chip extraction pipe 5 is used to connect to the chip extraction pump. When performing riser cutting operations, the chip extraction pipe 5 is connected to the external chip extraction pump. After the chip extraction pump is started, a negative pressure environment is formed in the chip extraction chamber inside the tooling plate 1. The waste chips generated during the cutting process are sucked into the chip extraction chamber through the chip extraction holes 101 on both sides of the cutting opening under the action of negative pressure suction, and then extracted through the chip extraction pipe 5. This structure realizes the real-time collection and cleaning of cutting waste chips. On the one hand, it can avoid the accumulation of waste chips at the cutting opening and affect the normal operation of the cutting tool, and prevent the tool from being worn more or stuck due to contact with waste chips. On the other hand, it can keep the working area clean and reduce the interference of waste chip splash to the operator.
[0038] In a specific embodiment, the end of the tooling plate 1 is connected to a connector 103 that communicates with the chip extraction chamber, and one end of the chip extraction tube 5 is connected to a plug 51 that is inserted into the connector 103. When installing the chip extraction tube 5, the plug 51 at the end of the chip extraction tube 5 is aligned with the connector 103 at the end of the tooling plate 1 and inserted, so that the chip extraction tube 5 can be quickly connected to the chip extraction chamber of the tooling plate 1. When it is necessary to disassemble the chip extraction tube 5 for cleaning or replacement, the plug 51 can be pulled out directly to complete the disassembly.
[0039] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model, and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
