Description

TECHNICAL FIELD

[0001] The utility model relates to high pressure cleaning tool cup replacement technical field, specifically a new tool cup structure for CNC high pressure cleaning. BACKGROUND

[0002] In the prior art, the tool clamping device of some numerical control machining equipment (CNC) usually adopts a plastic integral tool cup. Specifically, the tool cup produced by the injection molding process is a single plastic component, and its functionality depends on the inherent elastic deformation characteristics of the plastic material: during tool replacement, the tool cup generates radial contraction or expansion through a pre-set elastic deformation area to achieve rapid clamping and release of the tool. However, this technical solution has significant technical limitations: first, the plastic material is prone to molecular chain rupture, creep and stress relaxation under the action of long-term alternating stress, resulting in a gradual attenuation of the elastic modulus, and the clamping force will irreversibly decrease as the service period extends; second, the photo-oxidative degradation and thermal aging effects of the material will accelerate the brittle transition of the plastic, causing crack propagation or permanent plastic deformation in the key deformation parts of the tool cup; more significantly, since the tool cup and the tool are an integral structure, when the local functional units (such as the clamping jaws and deformation guide grooves) fail, the clamping device must be replaced in its entirety, which not only results in a large amount of waste of functional materials, but also significantly increases the material cost and downtime of equipment maintenance. Frequent replacement of spare parts under continuous production conditions has become a key bottleneck restricting the improvement of the operating efficiency of the machining system.

[0003] Therefore, a new tool cup structure for CNC high pressure cleaning is now being designed. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims to overcome the shortcomings of the prior art and provide a new tool cup structure for CNC high pressure cleaning to increase the service life of the tool cup structure and reduce the maintenance cost of the tool cup structure.

[0005] In order to achieve the above object, a new type of cutter cup structure for CNC high pressure cleaning is designed, which comprises a rack and a CNC cutter, the CNC cutter comprises two annular bosses arranged in upper and lower positions, a key groove is arranged on the upper annular boss, and a gap is left between the two annular bosses, and the cutter cup body is made of metal material, a plurality of through holes are arranged on the rear part of the cutter cup body for connecting the rack, and a circular arc-shaped notch is arranged on the front part of the cutter cup body and is shaped according to the CNC cutter; two support pieces are made of metal material and are arranged on the left and right sides of the cutter cup body respectively, a first step structure is arranged on the front part of the support piece, and a plurality of through holes are arranged on the rear part of the support piece for connecting the rack; two spring clamps are arranged on the first step structure of the two support pieces respectively, a spring clamp chuck head is arranged on the front part of the spring clamp and is bent to the left and right sides, a Y-shaped deformation groove is arranged in the middle of the spring clamp chuck head, the rear part of the spring clamp is provided with a through hole for connecting the support piece, and the spring clamp chuck head near the cutter cup body is bent to the inside of the circular arc-shaped notch.

[0006] Preferably, the lower side of the rear part of the spring clamp is matched with the lower tread of the first step structure, and the rear surface of the rear part of the spring clamp is matched with the kick surface of the first step structure.

[0007] Preferably, the utility model also includes that the outer side surface of the front part end of the spring clamp chuck head is provided with a limiting lug.

[0008] Preferably, the utility model also includes that the circular arc-shaped notch of the cutter cup body is provided with a second step structure.

[0009] Preferably, the utility model also includes that the height of the lower tread of the second step structure is aligned with the height of the lower tread of the first step structure.

[0010] Preferably, the utility model also includes that the middle part of the circular arc-shaped notch is provided with an anti-rotation piece, the anti-rotation piece is connected on the lower tread of the second step structure through a bolt, and the anti-rotation piece and the key groove on the CNC cutter form clamping.

[0013] Compared with the prior art, the utility model has the advantages that:

[0014] This invention employs a functionally decoupled, split design for the tool cup, constructing the elastic deformation unit and rigid support unit as a detachable modular component. The elastic deformation module uses plastic as its base material and features a uniquely shaped claw structure with an elastic modulus, enhancing its elastic deformation performance and improving the stability and flexibility of tool clamping. The rigid support module is made of aluminum alloy. This split structure allows the rigid module to effectively suppress lateral deflection when the elastic deformation module is subjected to axial clamping force. Compared to traditional integrated structures, this structure improves the fatigue life of the clamping mechanism, and the individual replacement of the elastic module reduces maintenance costs. Furthermore, the multi-degree-of-freedom adjustment interface between modules allows for adjustment of the clamping force based on differences in tool diameter, achieving dynamic matching and optimization of clamping stiffness and buffering characteristics.

[0021] To make the purpose, principle and structure of this utility model clearer, the following description is provided in conjunction with the accompanying drawings and specific embodiments.

[0022] See Figures 1-5 To achieve stable clamping and rapid assembly / disassembly of tools under high-pressure cleaning conditions, this embodiment provides a novel CNC tool cup structure, which comprises:

[0023] The support 12 and the CNC tool 9 are included. The support 12 is a conventional tool holder. The CNC tool 9 includes two annular bosses 9.1 arranged vertically. The upper annular boss 9.1 has a keyway 9.2, and a gap is left between the upper and lower annular bosses 9.1. Figure 4For example, the direction closer to the stand 12 is the rearward direction, and the direction closer to the tool 9 is the forward direction. Figure 4 The structure observed from a top-down perspective is the upper side, with Figure 5 The structure observed from an upward-looking perspective is on the lower side.

[0024] The cutter cup body 1 is fixed to the support 12 at the rear and extends out of the support 12 at the front, suspended in the air. It is made of hard aluminum alloy. The front part has an arc-shaped notch that matches the contour of the shank of a standard CNC tool 9. The inner wall of the notch is machined with a second step structure 1.1. The second step structure 1.1 of the cutter cup body 1 is fitted with the two annular bosses 9.1 on the upper and lower parts of the tool 9 with a clearance fit to stably hold the tool 9.

[0025] Two support members 2 are symmetrically distributed on the left and right sides of the blade cup body 1. The rear of the support member 2 is fixed on the stand 12 and the front is suspended. The support member 2 is not fixedly connected to the blade cup body 1. Each support member 2 has a first step structure 2.1 at its front end. The height of the lower step surface of the first step structure 2.1 is flush with the height of the lower step surface of the second step structure 1.1.

[0026] The spring clip 3 is integrally molded from plastic. It has a spring clip head 4 at the front, with two forked arms formed at the front end. These forked arms are bent outwards to form symmetrical inclinations, and each forked arm has a limiting protrusion 5 on its outer front end. The lower rear side of the spring clip 3 forms a surface contact constraint with the lower tread surface of the first step structure 2.1, and the side wall of the spring clip 3 forms an axial limiting fit with the kick surface of the first step structure 2.1.

[0027] The support member 2 and the spring clip 3 are machined with coaxial through holes 6 at their rear ends. The bolts are threaded into the through holes 6 to achieve a fast connection between the support member 2 and the spring clip 3.

[0028] Preferably, the middle part of the chuck 4 is provided with a Y-shaped deformation groove 7 between adjacent forked arms 4. When the forked arms of the chuck 4 with bent structure are deformed by compression, the two adjacent forked arms of the chuck 4 with bent structure can squeeze to eliminate the deformation groove 7 to realize the accumulation and release of elastic potential energy and prevent stress concentration.

[0029] Preferably, an anti-rotation component 8 is provided at the center of the arc-shaped notch of the blade cup body 1. The anti-rotation component is fixed to the middle part of the second step structure 1.1 by screws. Its top protrusion forms an interference fit with the keyway 9.2 of the handle of the blade 9 to bear the torque load. Since the anti-rotation component 8 is installed on the second step structure 1.1, and the blade 9 only has a keyway 9.2 on the upper annular boss 9.1, the anti-rotation component 8 can not only limit the upper annular boss 9.1 horizontally, but also limit the lower annular boss 9.2 vertically, thus truly preventing the blade 9 from flipping.

[0030] In the embodiment, the spring clip 3 is made of plastic material with elastic deformation performance, and the cutter cup body 1 is made of aluminum alloy, so that the elastic deformation and the rigid support are decoupled through the differential design of material performance.

[0031] The lower side of the cutter cup body 1 is further provided with a through slot 10 for accommodating a sensor 11, and the sensor 11 is used for detecting the position and existence of the cutter 9.

[0032] The above merely describes the specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and novel concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
