Description

Technical Field

[0001] This utility model belongs to the field of fixture structure technology, specifically relating to a fixture for coolant flow protection during tool processing. Background Technology

[0002] In CNC milling, turning, and other cutting processes, coolant is widely used in the contact area between the tool and the workpiece to reduce machining heat, minimize tool wear, and improve machining accuracy. Typically, coolant is sprayed from a nozzle onto the tool surface and flows under gravity to the fixture or machining platform. To ensure machining quality and operational safety, effective coolant flow and residual coolant recovery must be controlled.

[0003] In existing technologies, V-groove clamping blocks are often used to position and clamp tools, with screws driving the blocks downwards to press the tool. However, during use, if the clamping structure is unstable or the pressing mechanism cannot provide pure axial force, the tool may loosen or shift during clamping, affecting machining accuracy. Furthermore, some fixtures lack coolant recovery mechanisms, causing coolant to spill directly onto the machining platform surface during processing, potentially causing contamination or affecting subsequent machining operations.

[0004] Especially in high-precision machining scenarios, not only are higher requirements placed on the clamping accuracy of the cutting tools, but also on the directional flow and effective collection of coolant to avoid liquid accumulation in the machining area, splashing coolant that could injure people or corrode equipment. However, existing fixtures generally suffer from problems such as a disconnect between the clamping system and the flow guiding system, inconvenient structural assembly, and easy deflection or loosening of clamping components, making it difficult to meet the comprehensive usage needs of complex machining scenarios. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a tooling fixture for coolant flow protection during tool processing. It can realize a tool processing fixture with good coolant recovery function and easy installation and maintenance, which is a specific technical problem that urgently needs to be solved in the current technical field.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A clamp for coolant flow protection during tool processing includes a base, which is connected to the processing table by screws, and a positioning member is fixedly connected to the upper end face of the base. A clamping support member is connected to the positioning member, and a clamping pressure member is provided on the top of the clamping support member.

[0008] When machining, the tool is clamped between the clamping support and the clamping pressure member;

[0009] The top of the clamping support is provided with a first V-shaped groove;

[0010] The clamping and pressing component includes a top plate located at the top of the clamping support component. A screw is threaded through the top plate, and a pressing block is rotatably connected to the bottom of the screw. A second V-shaped groove is provided at the bottom of the pressing block.

[0011] A protective cover is connected to the clamping support.

[0012] Furthermore, the base is configured as a cavity with an opening at the bottom, and a through groove is provided at the edge of the bottom opening of the base, and a return pipe is inserted into one end of the base.

[0013] Furthermore, the bottom of the base is symmetrically and fixedly connected with a support base, and the support base has a through hole.

[0014] Furthermore, a limiting groove is formed on the top of the positioning member, and the bottom of the clamping support member is inserted into the limiting groove;

[0015] The inner wall of the limiting groove is symmetrically fixed with locking blocks, and both ends of the clamping support are provided with locking grooves that engage with the locking blocks.

[0016] The positioning member has symmetrical through holes on both sides, and the clamping support has first threaded grooves at both ends corresponding to the first connecting holes.

[0017] Furthermore, the top of the clamping support is symmetrically provided with a second threaded groove, and the top of the top plate is symmetrically provided with a second connecting hole corresponding to the second threaded groove.

[0018] Furthermore, a guide groove is provided in the first V-shaped groove, and the pressing block is located in the guide groove.

[0019] Furthermore, a base is provided on the top plate, and the screw passes through the base;

[0020] The top of the pressing block is provided with a rotating seat, and the bottom of the screw is rotatably connected to the rotating seat.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This fixture clamps the cutting tool by using a clamping support and a clamping pressure member to cooperate in clamping the tool. A first V-groove and a second V-groove are respectively set on their contact surfaces, which effectively realizes the axial limit and bidirectional clamping of the tool. It solves the problems of poor stability of the clamping structure and easy tool displacement in the prior art, and improves the fixation reliability and machining accuracy of the tool.

[0023] This clamp solves the problem of uneven clamping caused by the rotation of the clamping block in traditional clamping mechanisms by setting screws, rotating seats and clamping blocks in the clamping and pressing parts, and cooperating with the first V-shaped groove with guide grooves, so that the clamping block only generates axial clamping force during the rotation of the screw and avoids displacement, thereby enhancing the stability and clamping accuracy of the clamping structure.

[0024] This fixture features a hollow base with a through groove at its bottom connected to a return pipe. This effectively collects the coolant generated during tool processing and directs it into a recycling system, solving the problem of coolant leakage and environmental pollution in existing technologies. It also improves coolant utilization efficiency and the cleanliness of the equipment's working area.

[0025] This fixture features a limiting groove, a locking block, and a threaded fastening structure, which enables multiple locking between the clamping support and the positioning component. Furthermore, multiple threaded connections are added between the top plate and the clamping support, solving the problems of unstable assembly structure and easy loosening of clamping components in traditional fixtures, thus enhancing the rigidity and durability of the overall structure.

[0026] This fixture features protective covers on both sides of the clamping support, which effectively prevent coolant or metal shavings from splashing into the operating area. This solves the safety hazards that may be caused by the lack of protective measures during processing, and improves operational safety and ease of use. Attached Figure Description

[0042] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0043] See Figure 1-6 A clamping fixture for coolant flow protection during tool machining includes a base 1, which is connected to a machining table by screws 32. A positioning member 14 is fixedly connected to the upper end face of the base 1, and a clamping support member 2 is connected to the positioning member 14. A clamping pressure member 3 is provided on the top of the clamping support member 2. A first V-groove 23 for limiting the position of the tool is opened in the middle of the top of the clamping support member 2. The clamping pressure member 3 includes a top plate 31 located on the top of the clamping support member 2. The top plate 31 is threadedly installed with a second threaded groove 25 on the top of the clamping support member 2 through a second connecting hole 311. A base 312 is provided on the upper surface of the top plate 31. The base 312 has a threaded hole, and the screw 32 is threaded through the middle of the base 312. The bottom end of the screw 32 is rotatably connected to the rotating seat 332 on the top of the lower pressure block 33, ensuring that the lower pressure block 33 generates a pure axial clamping force when subjected to force. The bottom of the lower pressure block 33 has a second V-groove 331, which is used to cooperate with the first V-groove 23 to clamp the tool. The first V-groove 23 also has a guide groove 24. The lower end of the lower pressure block 33 extends into the guide groove 24 to form a limiting constraint and prevent it from deviating. The clamping support 2 is connected to the two sides of the clamping support 2. The protective cover 4 covers the two sides of the clamp to block the splashed coolant or metal chips during the processing and improve the safety of operation.

[0044] See Figure 1-2The base 1 is designed as a hollow cavity with an opening at the bottom, and a through groove 11 is provided at the edge of the bottom opening of the base 1. The through groove 11 is used to guide the coolant flowing down from the tool surface to collect inward, so as to prevent the liquid from leaking out and contaminating the machining table. A return pipe 13 is inserted into one end of the base 1. The return pipe 13 is connected to the through groove 11 and is used to further guide the coolant to the external recycling system, so as to realize the centralized collection and recycling of coolant, improve resource utilization and keep the machining environment clean.

[0045] See Figure 1-2 The bottom of the base 1 is symmetrically fixedly connected with a support seat 12. The support seat 12 is located at both ends of the base 1 and contacts the processing table surface. A fixing hole 121 is provided through the support seat 12. The fixing hole 121 is used to firmly install the fixture on the processing table by screws or bolts, which enhances the structural stability, prevents the fixture from shifting or loosening during processing vibration, and ensures the clamping accuracy and safety of the tool processing process.

[0046] See Figure 3-4 The positioning member 14 has a limiting groove 141 on its top, and the bottom of the clamping support member 2 is inserted into the limiting groove 141. The limiting groove 141 constrains and positions the clamping support member 2. A locking block 1411 is symmetrically fixedly connected to the inner side wall of the limiting groove 141. The locking block 1411 is used to engage with the locking grooves 21 set on both ends of the clamping support member 2 to achieve the initial limiting and positioning of the clamping support member 2. In order to achieve precise locking of the clamping support member 2, the positioning member 14 has a first connecting hole 142 symmetrically through both sides. The clamping support member 2 has a first threaded groove 22 corresponding to the first connecting hole 142 on both ends. The first connecting hole 142 and the first threaded groove 22 are fastened by screws, which further improves the stability of the overall structure of the fixture and the reliability of repeated assembly.

[0047] See Figure 4-5 The top of the clamping support 2 is symmetrically provided with a second threaded groove 25, which is used to cooperate in installing the top plate 31 in the clamping pressing component 3; the top of the top plate 31 is symmetrically provided with a second connecting hole 311 corresponding to the second threaded groove 25. The second connecting hole 311 and the second threaded groove 25 are connected by screws to realize the assembly and fixation of the clamping support 2 and the top plate 31, ensuring that the pressing structure maintains a good connection under stress and avoiding the clamping structure from loosening and affecting the processing accuracy.

[0048] See Figure 4A guide groove 24 is provided in the first V-shaped groove 23. The guide groove 24 is located at the center axis of the bottom of the V-shaped groove and is used to accommodate the bottom structure of the lower pressure block 33. The lower pressure block 33 is located in the guide groove 24. During the clamping process, the lower pressure block 33 is limited and constrained in the guide groove 24 to prevent it from lateral displacement during the clamping process, thereby improving the clamping accuracy and extending the service life of the fixture. This ensures that the tool is always kept in the center position of the fixture and improves the consistency of processing.

[0049] See Figure 5-6 A base 312 is provided on the top plate 31. The base 312 is located in the middle of the upper surface of the top plate 31, providing a support base for the installation of the screw 32. The screw 32 passes through the central screw hole of the base 312. The lower end of the screw 32 is connected to a rotating seat 332. The rotating seat 332 is located on the top of the lower pressure block 33. The rotating seat 332 and the screw 32 are rotatably connected. When the screw 32 is rotated, the rotating seat 332 only generates axial clamping force and does not rotate, so that the lower pressure block 33 moves downward steadily to achieve the clamping function, avoiding rotational interference during the clamping process and improving clamping accuracy and processing stability.

[0050] The working principle of this utility model is as follows:

[0051] In use, the tool is placed in the first V-groove 23 at the top of the clamping support 2, while the second V-groove 331 at the bottom of the clamping pressure member 3 is aligned with the other side of the tool. By rotating the screw 32, the pressure block 33 at its bottom end is gradually pressed downwards, thereby firmly clamping the tool between the V-grooves and achieving stable fixation of the tool. The clamping support 2 engages with the locking block 1411 inside the positioning member 14 through the locking groove 21, enhancing overall stability, and is further locked by the threaded engagement.

[0052] During machining, coolant is sprayed onto the tool surface for cooling, and some coolant flows downward with the tool. The base 1 is designed as a cavity structure, and the through groove 11 at the bottom edge is used to collect the flowing coolant, which is then guided to the recovery system through the return pipe 13 at one end, thereby preventing coolant from overflowing and polluting the machining environment.

[0053] The screw 32 passes through the top plate 31 and the base 312 thereon, and its bottom is rotatably connected to the rotating seat 332 on the lower pressure block 33. Thus, when the screw is rotated, it will not drive the lower pressure block to rotate, but only generate axial clamping force to ensure clamping stability. The guide groove 24 provides lateral limit for the lower pressure block 33 to prevent it from shifting during the clamping process and improve clamping accuracy.

[0054] The components are connected by screws with a first threaded groove 22 and a first connecting hole 142, a second threaded groove 25 and a second connecting hole 311, and a slot with a limiting groove 141 and a locking block 1411. This ensures the stability of the fixture while facilitating assembly and maintenance, and improving work efficiency.

[0055] The clamping support 2 is equipped with a protective cover 4, which can effectively block splashing coolant or debris during processing, preventing it from causing injury to the operator or equipment and improving overall safety.

[0056] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
