Description

Technical Field

[0001] This utility model belongs to the technical field of cutting tooling equipment, specifically relating to an ADI casting cutting tooling equipment. Background Technology

[0002] ADI casting cutting fixtures are specialized equipment used for positioning, clamping, motion guidance, and machining assistance when machining ADI material castings. Their core function is to ensure the stability, machining accuracy, and efficiency of ADI castings during the cutting process through structural design, and they are especially suitable for the characteristics of ADI materials and the complex machining requirements of castings (such as cutting curved surfaces and irregular surfaces).

[0003] Currently, most existing tooling adopts a static fixed and linear feed machining mode. A typical structure includes a base, a hydraulically driven double-sided clamping plate, and a cutting unit that moves in the horizontal or vertical direction. During machining, the ADI casting is fixed to the positioning position of the base by the clamping plate. The cutting motor drives the tool to rotate at high speed, while the cutting unit is driven to make linear motion by the cylinder or ball screw. However, this type of equipment has certain defects. It can only complete plane milling, end face flattening, or fixed angle bevel cutting. If it is necessary to machine the arc transition surface of the inner ring of the bearing housing, it is necessary to transfer it to a special lathe for secondary machining. This is not only cumbersome, but also prone to positioning errors due to repeated clamping of the workpiece. Utility Model Content

[0004] The purpose of this invention is to provide an ADI casting cutting tooling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ADI casting cutting fixture, comprising a base, an adjusting seat fixedly connected to the base, a support block fixedly connected to the middle position of the adjusting seat, a movable bolt disposed on the support block, a fixed rod movably connected to the movable bolt, two sets of fixed rods symmetrically arranged along the support block, a sliding block sleeved on the fixed rod, a connecting block hinged to the sliding block, a bearing block fixedly connected above the connecting block, a connecting rod hinged to one side of the bearing block, a driving block hinged to the other end of the connecting rod, and a screw drively connected to the driving block.

[0006] In a preferred embodiment, a positioning seat is fixedly installed on one side of the base, the screw is rotatably installed on the positioning seat, and a reciprocating motor is assembled on the side wall of the positioning seat, the output end of the reciprocating motor being connected to the screw drive.

[0007] In a preferred embodiment, an ADI-machined casting is placed on the support block, and both the support block and the ADI-machined casting have the same positioning holes.

[0008] In a preferred embodiment, an L-shaped plate is fixedly connected to one side of the base, a cutting motor is mounted on the L-shaped plate, and a cutting tool is installed at the output end of the cutting motor.

[0009] In a preferred embodiment, the cutting tool is mounted directly above the support block.

[0010] In a preferred embodiment, a vertical block is also fixedly installed on the adjusting seat. The vertical block has a fixing groove, and a fixing bolt is configured in the fixing groove. The fixing rod is fixed in the fixing groove in cooperation with the fixing bolt.

[0011] In a preferred embodiment, the fixing groove is specifically an arc-shaped groove structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This ADI casting cutting fixture uses a symmetrically arranged fixed rod, sliding block and connecting block to form a linkage support structure. When used with a drive block, screw and reciprocating motor, it can drive the bearing block to move in a circular motion. Combined with the cutting tool set at the top, it can directly complete the curved surface cutting of ADI castings. It breaks through the limitation of traditional fixtures that can only perform plane or simple inclined plane cutting. It does not require multiple machines to process in steps, and significantly improves the convenience and efficiency of processing complex ADI castings. This ADI casting cutting fixture, through the cooperation of the arc-shaped fixing groove and fixing bolt on the vertical block, can flexibly adjust the tilt angle of the fixing rod, thereby changing the motion trajectory parameters of the bearing block and adapting to the processing requirements of surfaces with different curvatures. At the same time, the bearing block and the ADI casting are positioned through the same positioning hole, and with the stable support of the fixing rod, the stability of the casting position during the cutting process is effectively guaranteed, which greatly improves the accuracy and adaptability of ADI casting surface processing.

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figures 1-4 This utility model provides an ADI casting cutting fixture, including a base 1, an adjusting seat 2 fixedly connected to the base 1, a support block 22 fixedly connected to the middle of the adjusting seat 2, a movable bolt 24 configured on the support block 22, the movable bolt 24 being movably connected to a fixed rod 3, two sets of fixed rods 3 symmetrically arranged along the support block 22, a sliding block 4 sleeved on the fixed rod 3, a connecting block 5 hinged to the sliding block 4, a bearing block 6 fixedly connected above the connecting block 5, an ADI machining casting 7 placed on the bearing block 6, both the bearing block 6 and the ADI machining casting 7 having the same positioning hole 61, a connecting rod 9 hinged to one side of the bearing block 6, a driving block 91 hinged to the other end of the connecting rod 9, a screw 92 being driven to the driving block 91, an L-shaped plate 11 fixedly connected to one side of the base 1, a cutting motor 100 mounted on the L-shaped plate 11, a cutting tool 101 mounted at the output end of the cutting motor 100, and the cutting tool 101 mounted directly above the bearing block 6.

[0018] In this embodiment, a linkage support structure is formed by two sets of symmetrically arranged fixed rods 3 (with different inclination angles), sliding block 4, and connecting block 5. This structure works in conjunction with connecting rod 9, drive block 91, and screw 92. During operation, reciprocating motor 93 drives screw 92 to rotate, and drive block 91 moves along the axial direction of screw 92. At this time, the connecting rod 9 pushes and pulls the bearing block 6, while the sliding block 4 along the fixed rod 3 provides stable guidance for the bearing block 6. Ultimately, the bearing block 6 drives the ADI machining casting 7 to achieve circular motion. At the same time, the cutting tool 101 is mounted directly above the bearing block 6 and can directly perform curved surface cutting on the ADI machining casting 7 along with the circular motion of the bearing block 6.

[0019] Compared to traditional tooling that can only cut planes or simple inclined planes, this application does not require multiple machines for step-by-step processing, nor does it require multiple machine stops to adjust the angle of the ADI-processed casting 7. It can complete the integrated cutting of complex curved surfaces such as arc end faces and arc transition surfaces in one go.

[0020] Please see Figure 1 , Figure 2 and Figure 4 A positioning seat 8 is fixedly installed on one side of the base 1, and a screw 92 is rotatably installed on the positioning seat 8. A reciprocating motor 93 is assembled on the side wall of the positioning seat 8, and the output end of the reciprocating motor 93 is connected to the screw 92 for transmission.

[0021] In this embodiment, the reciprocating motor 93 can drive the screw 92 to rotate in both directions, thereby causing the drive block 91 to move in both directions along the screw 92. The connecting rod 9 pulls or pushes the bearing block 6, allowing the bearing block 6 to achieve reciprocating circular motion under the constraint of the fixed rod 3, reducing operational errors caused by manual intervention.

[0022] Please see Figure 1 and Figure 2 A vertical block 21 is also fixedly installed on the adjusting seat 2. The vertical block 21 has a fixing groove, and a fixing bolt 23 is configured in the fixing groove. The fixing rod 3 is fixed in the fixing groove in cooperation with the fixing bolt 23. The fixing groove is specifically an arc-shaped groove structure.

[0023] In this embodiment, the vertical block 21 fixedly installed on the adjusting seat 2 has an arc-shaped fixing groove. With the fixing bolt 23, the tilt angle of the fixing rod 3 can be flexibly adjusted. Since the fixing rod 3 is movably connected to the support block 22 through the movable bolt 24, after the fixing bolt 23 is loosened, the fixing rod 3 can rotate around the movable bolt 24, and its end can move along the arc-shaped fixing groove. After adjusting to the target angle, the fixing bolt 23 can be tightened again to lock the fixing rod 3. When there are various curvatures of ADI machining castings 7, the radius of the circumferential motion trajectory of the bearing block 6 can be changed simply by adjusting the tilt angle of the fixing rod 3. There is no need to replace the fixing rod 3 or redesign the positioning structure, so that the equipment can be adapted to the surface cutting of ADI machining castings 7 of various specifications.

[0024] The working principle and usage process of this utility model are as follows: First, place the ADI machining casting 7 to be processed on the support block 6, align the positioning hole 61 of the support block 6 and the ADI machining casting 7, and use bolts to pass through the positioning hole 61 and tighten them to fix the ADI machining casting 7 on the support block 6. Next, according to the different curvatures of the surface being processed, loosen the fixing bolt 23 on the vertical block 21, push the fixing rod 3 to rotate around the movable bolt 24 of the support block 22, so that the end of the fixing rod 3 moves along the arc-shaped fixing groove to the target angle, and after adjustment, tighten the fixing bolt 23 to lock the fixing rod 3. Then, the reciprocating motor 93 on the side wall of the positioning seat 8 and the cutting motor 100 on the L-shaped plate 11 are turned on. The cutting motor 100 drives the cutting tool 101 to rotate at high speed. The reciprocating motor 93 drives the screw 92 to rotate in both directions, so that the drive block 91 moves along the axial direction of the screw 92. The bearing block 6 is pushed and pulled through the connecting rod 9. At this time, the sliding block 4 slides along the fixed rod 3 to provide guidance for the bearing block 6, which drives the ADI machining casting 7 to make a circular motion. The cutting tool 101 performs integrated curved surface cutting on the ADI machining casting 7 directly above the bearing block 6. Finally, after the surface cutting is completed, turn off the reciprocating motor 93 and the cutting motor 100, loosen the bolt at the positioning hole 61, remove the ADI machined casting 7, loosen the fixing bolt 23 and reset the fixing rod 3, and prepare for the next machining.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
