[0002] CNC optical-mechanical casting fixing devices are used for castings of basic structures and support components of CNC machine tools. When machining connecting shaft castings, it is necessary to limit the movement of the castings by clamping and fixing devices to facilitate better machining. For example:

[0003] CN220481475U discloses an adjustable casting fixing device, comprising a fixed base, a casting fixing seat mounted on the upper end of the fixed base, support rods mounted on both sides of the upper end of the fixed base, and a drive assembly mounted on the upper end of the fixed base; a lifting assembly mounted on the top of the two support rods, and a top plate mounted on the top of the lifting assembly; a casting fixing seat b mounted on the lower end of the top plate, and both casting fixing seats a and b having casting fixing grooves inside; a drive cavity inside the fixed base, a rotating hole with a rotating rod installed in the middle of the top of the drive cavity; a bearing seat mounted on the bottom of the drive cavity, the lower end of the rotating rod installed in the bearing seat, and the upper end of the rotating rod connected to the casting fixing seat a; this adjustable casting fixing device can change the position of the casting as needed, avoiding the need to re-fix the casting when other surfaces of the casting need to be processed, increasing work efficiency and facilitating actual operation.

[0004] The existing technical solutions have the following drawbacks, such as:

[0005] 1. Existing casting fixing devices, when machining the connecting shaft, do not provide sufficient reinforcement, which can easily cause the connecting shaft to fall off during machining, affecting the machining effect. At the same time, the machining angle is too limited, and it is not convenient to perform automatic adjustment of multiple angles while reinforcing. Therefore, this utility model provides a CNC optical-mechanical casting fixing device with a positioning structure to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a CNC optical-mechanical casting fixing device with a positioning structure, so as to solve the problems mentioned in the background art, where the connecting shaft is not tightly reinforced when processing, which can easily cause the connecting shaft to fall off during processing and affect the processing effect. At the same time, the processing angle is too limited, and it is not convenient to perform automatic adjustment of multiple angles while reinforcing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a CNC optical-mechanical casting fixing device with a positioning structure, comprising: a machining platform, a connecting shaft machining body disposed in the middle of the machining platform, and an adjustable reinforcing component connected to the outside of the connecting shaft machining body, and further comprising:

[0008] The upper surface of the processing platform is connected to a first connector and a second connector respectively. The first connector and the second connector are fixed to the processing platform in parallel. The first connector is connected to a first connecting rod inside, and the second connector is connected to a second connecting rod inside.

[0009] An adjustable positioning component is provided inside both the first connecting rod and the second connecting rod, and a first motor connected to the first connecting rod is provided on the outside of the first connecting member.

[0010] As a preferred embodiment of this utility model, the first connecting rod and the second connecting rod are arranged in parallel.

[0011] As a preferred embodiment of the present invention, the reinforcing component includes mounting blocks that pass through the interior of the first connecting rod and the second connecting rod respectively, and a limiting plate is fixed to the inner end of the mounting block, and a positioning shaft block is connected to the inner end of the limiting plate.

[0012] As a preferred technical solution of this utility model, the limiting plate is provided in two sets between the first connecting member and the second connecting member, and the cross-section of the limiting plate is a semi-arc structure.

[0013] As a preferred technical solution of this utility model, the limiting plate is rotatably connected to the positioning shaft block, and the positioning shaft block is set at equal angles inside the limiting plate to prevent wear on the outer end of the connecting shaft processing body.

[0014] As a preferred technical solution of this utility model, the mounting block and the first connecting rod are connected in a sliding manner to stabilize the movement of the mounting block.

[0015] As a preferred embodiment of this utility model, the second connecting rod is connected to the mounting block by opposite threads at both ends.

[0016] As a preferred technical solution of this utility model, the positioning component includes a second motor disposed in the middle of the processing platform, and a placement plate is connected to the upper end of the second motor. An auxiliary connecting block is fixed at an equal angle on the upper side of the placement plate. An adjusting rod is threadedly connected to the internal part of the auxiliary connecting block, and a pressing plate is installed at the lower end of the adjusting rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the CNC optical-mechanical casting fixing device with positioning structure can adjust and clamp the outer side of the workpiece through adjustable reinforcement components, and limit the workpiece through positioning components, thereby reducing wear on the workpiece while performing multi-angle clamping processing.

[0018] The first connecting rod and the second connecting rod are arranged in parallel. The threads at both ends of the first connecting rod are reverse threads. At this time, the mounting block moves relative to the first connecting rod. The inner end of the mounting block is fixed with a limit plate, and the inner end of the limit plate is connected with a positioning shaft block. When the mounting block moves relative to the first connecting rod, the mounting block drives the limit plate and the positioning shaft block on the inner side of the mounting block to move accordingly, thereby moving the limit plate relative to the first connecting rod. The cross-section of the limit plate is a semi-arc structure, which clamps and limits the outer side of the connecting shaft machining body.

[0019] An adjusting rod is connected to the internal thread of the auxiliary connecting block. After clamping and limiting the machining body of the connecting shaft, the adjusting rod inside the auxiliary connecting block is rotated, causing the pressing plate at the lower end of the adjusting rod to move. At the same time, the placement plate is fixedly connected to the auxiliary connecting block. When the pressing plate moves, the hole groove at the inner end of the machining body of the connecting shaft is reinforced and clamped by the pressing plate, increasing the stability of clamping the machining body of the connecting shaft.

[0020] The positioning plate is rotatably connected to the positioning shaft block, and the positioning shaft block is set at equal angles inside the positioning plate. When the second motor is started, it drives the placement plate to rotate. Thus, under the limitation of the pressing plate on the connecting shaft processing body, the connecting shaft processing body rotates synchronously with the placement plate. This allows for multi-angle rotation of the connecting shaft processing body, facilitating multi-angle rotation processing. The positioning shaft block is set at equal angles inside the positioning plate. When the connecting shaft processing body rotates synchronously on the surface of the placement plate, the positioning plate limits the connecting shaft processing body. At this time, the positioning shaft block, which is attached to the outer end of the connecting shaft processing body, rotates inside the positioning plate, thereby reducing wear on the outer end of the connecting shaft processing body while clamping.

[0028] 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.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a CNC optical-mechanical casting fixing device with a positioning structure, including a support leg 1, a processing platform 2, a first connecting member 3, a second connecting member 4, a first motor 5, a first connecting rod 6, a second connecting rod 7, a second motor 8, a placement plate 9, a connecting shaft processing body 10, a mounting block 11, a limiting plate 12, a positioning shaft block 13, an auxiliary connecting block 14, an adjusting rod 15, a mounting groove 16, and a pressing plate 17.

[0030] Working principle: When using this CNC optomechanical casting fixing device with a positioning structure, the specific details are as follows: Figure 1 , Figure 2 and Figure 5In this process, a support leg 1 is provided at the lower end of the processing platform 2 to place the processing platform 2. A connecting shaft processing body 10 is provided in the middle of the processing platform 2, and the connecting shaft processing body 10 is placed on the surface of the processing platform 2. A reinforcing component is provided on the outside of the connecting shaft processing body 10. A first connecting member 3 and a second connecting member 4 are respectively connected to the outer end of the upper surface of the processing platform 2, and the first connecting member 3 and the second connecting member 4 are fixed parallel to each other on the processing platform 2. A first motor 5 is provided on the outside of the first connecting member 3. The first motor 5 is started, and a first connecting rod 6 is connected inside the first connecting member 3. Since the output end of the first motor 5 is connected to the first connecting rod 6, the first motor 5, connected to the first connecting rod 6, rotates the first connecting rod 6 under the start of the first motor 5. The first connecting rod 6 is connected to the second connecting rod 6. The rods 7 are arranged in parallel. The second connecting rod 7 is internally connected to the second connecting member 4. The outer surfaces of the first connecting rod 6 and the second connecting rod 7 are provided with mounting blocks 11. When the first motor 5 drives the first connecting rod 6 to rotate, since the first connecting rod 6 and the mounting block 11 are threaded, and the second connecting rod 7 and the mounting block 11 are slidably connected, and the threads at the left and right ends of the first connecting rod 6 are reverse threads, the mounting block 11 moves relative to the first connecting rod 6. The inner end of the mounting block 11 is fixed with a limit plate 12, and the inner end of the limit plate 12 is connected with a positioning shaft block 13. When the mounting block 11 moves relative to the first connecting rod 6, the mounting block 11 drives the limit plate 12 and the positioning shaft block 13 on the inner side of the mounting block 11 to move accordingly, thereby moving the limit plate 12 relative to the first connecting rod 6. The cross-section of the limit plate 12 is a semi-arc structure, which clamps and limits the outer side of the connecting shaft machining body 10.

[0031] Specific examples Figure 3 , Figure 4 and Figure 6In this process, a positioning component is provided at the lower end of the connecting shaft processing body 10. Since the placement plate 9 is connected within the mounting groove 16, the positioning component includes an auxiliary connecting block 14 fixed at an equal angle to the upper side of the placement plate 9. An adjusting rod 15 is threadedly connected inside the auxiliary connecting block 14, and a pressing plate 17 is installed at the lower end of the adjusting rod 15. When the connecting shaft processing body 10 is clamped and limited, rotating the adjusting rod 15 inside the auxiliary connecting block 14 causes the pressing plate 17 at the lower end of the adjusting rod 15 to move accordingly. Simultaneously, the placement plate 9 is fixedly connected to the auxiliary connecting block 14. When the pressing plate 17 moves, it reinforces and clamps the inner end of the connecting shaft processing body 10 through the pressing plate 17, increasing the stability of the clamping of the connecting shaft processing body 10. The positioning component also includes a second motor 8 located in the middle of the processing platform 2, and the upper end of the second motor 8... The device is connected to a placement plate 9. The second motor 8 drives the placement plate 9 to rotate, causing the pressing plate 17 to limit the movement of the connecting shaft machining body 10, thus allowing the connecting shaft machining body 10 to rotate synchronously with the placement plate 9. This enables multi-angle rotation of the connecting shaft machining body 10, facilitating multi-angle machining. The limiting plate 12 is rotatably connected to the positioning shaft block 13, which is equidistantly positioned inside the limiting plate 12. When the connecting shaft machining body 10 rotates synchronously on the surface of the placement plate 9, the limiting plate 12 limits its movement. The positioning shaft block 13, which is attached to the outer end of the connecting shaft machining body 10, rotates inside the limiting plate 12, thus reducing wear on the outer end of the connecting shaft machining body 10 while clamping it. This is the method of using this CNC optical-mechanical casting fixing device with a positioning structure.
