Description

Technical Field

[0001] This utility model relates to the field of CNC tool processing equipment technology, specifically to a clamp-type CNC tool processing fixing device. Background Technology

[0002] CNC cutting tools are tools used for cutting processes in mechanical manufacturing. They are widely used in various CNC machine tools, such as CNC lathes, milling machines, drilling machines, and boring machines. They play a core role in automated machining processes, responsible for key operations such as cutting, drilling, milling, and boring. When machining with CNC cutting tools, the tool to be machined needs to be fixed in a fixture, and then the fixed fixture, along with the CNC cutting tool, is installed in the operating area of ​​the CNC cutting tool machining equipment. The machining equipment then processes the CNC cutting tool.

[0003] The Chinese utility model patent with authorization announcement number "CN222971538U" is specifically "a clamping type CNC tool machining fixing device". It adopts a clamping design, which uses two identical clamping blocks to fix the tool body and its connecting components in an appropriate position. This method can provide uniform clamping force and make the tool body more firmly fixed.

[0004] While the CNC tool fixing device in the above-mentioned apparatus can fix multiple CNC tools at the same time, it cannot disassemble or adjust the position of a single CNC tool after fixing, resulting in poor practicality. Furthermore, the chips generated during machining will enter the fixing device, affecting the machining accuracy of the CNC tools. Therefore, we propose a clamp-type CNC tool machining fixing device. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a clamping type CNC tool machining fixing device, which can effectively solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a clamp-type CNC tool machining fixing device, including: A fixing base, wherein two symmetrically distributed mounting feet are fixedly connected to the outer side of the fixing base, and through mounting holes are provided on the outer side of the mounting feet; The clamping mechanism includes multiple tool slots opened on the top of the fixed base. Two symmetrically distributed air chambers are opened on the inner wall of the tool slots. A clamping block for tool positioning is provided inside the air chamber. Two branch pipes communicating with the corresponding air chambers are fixedly connected to the outside of the fixed base. A T-connector is installed at the other end of the two branch pipes. The cleaning mechanism includes internal and external threaded rings threaded to the inner wall of the tool groove. A slide rail is installed on the outer side of the fixed base. A sliding sleeve is slidably connected to the outer side of the slide rail. A rotatable connecting plate is provided above the sliding sleeve. A cleaning nozzle is installed on the inner wall of the connecting plate.

[0007] Preferably, a sealing ring is fixedly connected to the outside of the clamping block, and the outside of the sealing ring is in close contact with the inner wall of the air cavity.

[0008] Preferably, a solenoid valve for controlling the opening and closing of the branch pipe is provided in the middle of the branch pipe, and a main pipe for connecting to the gas supply equipment is installed on the inner wall of the other interface of the tee joint.

[0009] Preferably, the inner wall of the inner and outer threaded rings is threaded with a threaded rod, and a rotating block is fixedly connected to the bottom end of the threaded rod.

[0010] Preferably, rubber pads are fixedly connected to the opposite surfaces of the two clamping blocks, and convex strips with equal spacing are provided on the outer sides of the two rubber pads.

[0011] Preferably, a rotating rod is fixedly connected to the top of the sliding sleeve, and the connecting plate is movably connected to the top of the rotating rod via a bearing.

[0012] Preferably, the inlet of the cleaning nozzle is equipped with an inlet pipe.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model, by setting up a clamping mechanism, allows several CNC tools to be processed to be placed into the tool slot during CNC tool machining. The air supply equipment injects air into the air chamber through the main pipe and branch pipe. As the gas is injected, it pushes the clamping block inside the air chamber to move, clamping the CNC tools to be processed and ensuring the stability of the CNC tools during machining. The opening and closing of the branch pipe can be controlled by the solenoid valve, so that the clamping of a single CNC tool can be canceled as needed, and the tool can be removed or its position adjusted, making the fixing device highly practical.

[0014] 2. This utility model uses a cleaning mechanism to remove the internal and external threaded rings from the tool groove by rotating them. At this time, some of the debris remaining in the tool groove is discharged. Then, the cleaning nozzle is used to clean the debris remaining in the tool groove, so that the tool groove is clean and the accuracy of CNC tool machining is ensured. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] Example 1: Reference Figure 1-5 This is the first embodiment of the present invention, which discloses a clamp-type CNC tool machining fixing device, comprising: The fixed base 1 has two symmetrically distributed mounting feet 2 fixedly connected to its outer side, and the mounting feet 2 have through mounting holes 3 on their outer sides; In actual operation, the entire fixing device can be securely installed onto the worktable or designated position of the processing equipment by means of mounting feet 2 and mounting holes 3, for example by bolts.

[0021] The clamping mechanism 5 includes multiple tool slots 501 formed on the top of the fixed base 1. Two symmetrically distributed air chambers 505 are formed on the inner wall of the tool slots 501. A clamping block 509 for tool positioning is provided inside the air chamber 505. Two branch pipes 502 that communicate with the inside of the corresponding air chamber 505 are fixedly connected to the outside of the fixed base 1. A three-way connector 507 is installed at the other end of the two branch pipes 502.

[0022] Specifically, a sealing ring 508 is fixedly connected to the outside of the clamping block 509, and the outside of the sealing ring 508 is tightly fitted to the inner wall of the air chamber 505.

[0023] The sealing ring 508 ensures that when gas is injected, the clamping block 509 can move within the gas cavity 505 under the action of gas to clamp the CNC tool.

[0024] Specifically, a solenoid valve 504 for controlling the opening and closing of the branch pipe 502 is installed in the middle, and a main pipe 503 for connecting to the gas supply equipment is installed on the inner wall of the other interface of the tee connector 507.

[0025] Solenoid valve 504 is used to control the opening and closing of branch pipe 502, and three-way valve facilitates the entry of air from the main pipe 503 into the two branch pipes 502.

[0026] Specifically, the inner wall of the internal and external threaded ring 407 is threaded with a threaded rod 506, and a rotating block 512 is fixedly connected to the bottom end of the threaded rod 506.

[0027] The threaded rod 506 can adjust the insertion depth of the CNC tool in the tool slot 501 to meet the processing requirements of different CNC tools, and the rotating block 512 facilitates the rotation of the threaded rod 506.

[0028] Specifically, rubber pads 511 are fixedly connected to the opposite surfaces of the two clamping blocks 509, and convex strips 510 with equal spacing are provided on the outer sides of the two rubber pads 511.

[0029] The rubber pad 511 and the raised strip 510 provide anti-slip properties, ensuring the stability of the CNC tool clamping.

[0030] Ensure that the clamping block 509 can firmly and non-sliply clamp the tool. After clamping, close the branch pipe 502 through the solenoid valve 504 to cut off the air source and seal the air pressure in the air chamber 505, so that the clamping block 509 remains clamped. At this time, the processing equipment can perform processing operations on the CNC tool.

[0031] When it is necessary to remove or adjust one or more cutting tools, simply open the solenoid valve 504 on the branch pipe 502 connected to the air chamber 505 of the corresponding cutting tool slot 501 to release the compressed air inside the air chamber 505. After depressurization, the clamping block 509 will release under its own weight or the rebound force of the built-in spring or the sealing ring 508, and will no longer apply pressure to the cutting tool. At this time, the cutting tool can be easily removed from the cutting tool slot 501 or its position adjusted.

[0032] Example 2: Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that: The cleaning mechanism 4 includes internal and external threaded rings 407 that are threaded to the inner wall of the tool groove 501. A slide rail 401 is installed on the outer side of the fixed base 1. A sliding sleeve 402 is slidably connected to the outer side of the slide rail 401. A rotatable connecting plate 406 is provided above the sliding sleeve 402. A cleaning nozzle 404 is installed on the inner wall of the connecting plate 406.

[0033] The position of the cleaning nozzle 404 can be adjusted by the slide rail 401 and the slide sleeve 402, so as to clean the inside of different tool grooves 501.

[0034] Specifically, a rotating rod 405 is fixedly connected to the top of the sliding sleeve 402, and a connecting plate 406 is movably connected to the top of the rotating rod 405 via a bearing.

[0035] Under the action of the rotating rod 405, the connecting plate 406 can rotate, so as to prevent the cleaning nozzle 404 from affecting the processing when the CNC tool is being processed.

[0036] Specifically, the inlet of the cleaning nozzle 404 is equipped with an inlet pipe 403.

[0037] The water inlet pipe 403 provides a stable water source for the cleaning nozzle 404.

[0038] The remaining structure is the same as that in Example 1.

[0039] The workflow of this utility model is as follows: When machining with CNC cutting tools, the fixing device is moved to the machining equipment and fixed using mounting feet 2 and mounting holes 3; When fixing the CNC tool, the CNC tool to be machined is placed into the tool slot 501. Air is injected into the main pipe 503 and enters the corresponding branch pipe 502 through the tee connector 507. Finally, the air is injected into the air chamber 505 through the branch pipe 502, which pushes the clamping block 509 to clamp the CNC tool. After the CNC tool is clamped, the branch pipe 502 is closed by the solenoid valve 504. At this time, the CNC tool can be machined by the machining equipment. When it is necessary to remove or adjust the position of one or more CNC tools, open the solenoid valve 504 at the corresponding branch pipe 502 to discharge the air inside the air chamber 505. At this time, the CNC tools in the tool slot 501 can be disassembled or their position adjusted. Rotate the internal and external threaded rings 407 periodically to remove them from the tool groove 501. At this time, the remaining machining debris inside the tool groove 501 can be discharged to the outside of the tool groove 501. Then, the sliding sleeve 402 slides on the slide rail 401, thereby driving the cleaning nozzle 404 to move. The cleaning nozzle 404 rinses the inside of the tool groove 501, achieving the purpose of cleaning the tool groove 501.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
