Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of milling cutter grinding machine, in particular to a milling cutter grinding machine integrated with pneumatic debris treatment. BACKGROUND

[0002] At present, as an important equipment in the field of mechanical processing, the milling cutter grinding machine is mainly used for repairing the worn or broken milling cutter to prolong the tool life and reduce the processing cost. However, the milling cutter grinding machine in the prior art still has significant defects in structural design, operation efficiency and debris treatment. Specifically, a large amount of metal debris and hard alloy powder will be generated during the grinding process of the traditional equipment. The debris will splash due to the imperfect protective structure of the equipment (such as the exposed top of the protective box), which not only pollutes the working environment, but also may cause safety accidents due to the mistaken touch of the operator. For example, when the powder concentration reaches 40g / m³, it may explode when encountering an electric spark, and the powder carcinogen will be inhaled into the human body, and the powder will be stuck in other equipment.

[0003] At present, the above-mentioned defects are solved by stopping and blowing or actively guiding the debris to be discharged by high-pressure airflow or negative pressure device. However, there are still some problems in this solution, specifically:

[0004] 1. The metal powder will adhere to the filter structure, which may reduce the filtering effect or even cause the motor to overheat and burn out.

[0005] 2. In order to not affect the filtering effect, the metal powder adhered to the filter structure needs to be replaced regularly. If it is not replaced in time, the above-mentioned problems of reduced filtering effect and motor overload will occur. Therefore, a regular replacement alarm device needs to be installed, which further increases the structural complexity. If it is not installed, it is difficult to control the replacement time. At the same time, when the structure is complex, the metal powder may affect the precision instruments.

[0006] 3. The metal powder collected on the filter structure is adsorbed under the action of high-pressure airflow or negative pressure device. When the high-pressure airflow or negative pressure device stops, the metal powder will not always adhere to the filter structure, especially when the metal powder reaches a certain amount. The high-pressure airflow or negative pressure device is always started, which can avoid the change of the position of the metal powder, but the energy consumption is further increased. SUMMARY

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see Figures 1-9 This invention provides a technical solution: Current milling cutter grinding machines employ a method of purging after shutdown or actively guiding debris discharge via high-pressure airflow or negative pressure devices. This method has several problems, including metal powder adhering to the filter structure, which can reduce filtration efficiency or even cause motor overload and burnout. To prevent this, the metal powder adhering to the filter structure needs to be replaced periodically. Failure to replace it in time results in the aforementioned reduced filtration efficiency and motor overload problems, necessitating the installation of a timed replacement alarm device. Furthermore, when the high-pressure airflow or negative pressure device stops, the metal powder does not remain adhered to the filter structure and can easily disperse into the environment. Based on these issues, a milling cutter grinding machine integrating pneumatic debris handling is proposed. Figures 1-3 As shown, it includes a grinding base 1, a positioning shell 2, and a grinding wheel 3 inside the positioning shell 2, and includes a negative pressure generating part, a metal frame 6, a filter layer 7, and a transmission part 8.

[0051] The negative pressure generating unit is installed on the upper end of the grinding base 1. The negative pressure generating unit generates negative pressure by an external air pump.

[0052] The metal frame 6 has an integral bending rod 63, which is rotatably installed in the negative pressure generating part. The "V" opening of the bending rod 63 faces upward and is in contact with the deformation layer 71 of the filter layer 7. The shape of the deformation layer 71 remains stable.

[0053] The filter layer 7 has a deformed layer 71 fixed on the upper end of the metal frame 6 and located at the lower end of the grinding wheel 3. The metal powder generated by the grinding of the grinding wheel 3 moves downward under the action of negative pressure and adheres to the filter layer 7, preventing the metal powder from moving outward from the positioning shell 2. The filter layer 7 adsorbs the powder under the action of negative pressure, and the deformed layer 71 deforms. The deformed layer 71 recovers to clamp the powder. When the filter layer 7 is affected by negative pressure, the deformed layer 71 pushes the metal frame 6 downward, the bent rod 63 opens, and the deformed layer 71 opens while moving downward under the action of the deformed bent rod 63. At the same time, the separated filter layer 7 on both sides of the deformed layer 71 will tilt and move towards the deformed layer 71. When the deformed layer 71 moves downward and opens, the metal powder is concentrated in the deformed layer 71 under the influence of negative pressure and the inclined surface, so that the remaining part of the filter layer 7 maintains the ability to filter and avoids affecting the air pump. When the deformed layer 71 is not affected by negative pressure, the metal frame 6 will recover, and the metal powder in the deformed layer 71 is clamped by the recovery of the deformed layer 71. The clamped metal powder is pressed to the minimum extent to prevent flying.

[0054] The transmission part 8 is connected between the grinding seat 1 and the grinding wheel 3, and is connected with the metal frame 6 on the outside. The transmission part 8 drives the metal frame 6 and the filter layer 7 to rotate through the planetary gear set inside the transmission part 8. When the milling cutter is grinding, the position of the milling cutter is kept unchanged, and the metal powder generated moves downward. The rotating filter layer 7 can make the metal powder distributed on its upper end in a circular manner, avoiding the blockage of the filter layer 7 at a local position due to excessive concentration of metal powder.

[0055] Specifically, the positioning shell 2 is located at the upper end of the grinding seat 1, and the grinding seat 1 has a motor inside for driving the rotation of the grinding wheel 3 in the positioning shell 2. The positioning shell 2 is a combination of a chuck and a collet, which functions to achieve accurate correction and fixation of the milling cutter by cooperating with the grinding seat 1. The driving action of the motor drives the rotation of the grinding wheel 3 and also drives the transmission part 8, which realizes the rotation of the metal frame 6 and the filter layer 7.

[0056] It should be noted that filter layer 7 uses paper, non-woven fabric, or other fibrous materials as a flexible substrate, with a surface coated with a 3-200μm micron-scale structure formed by nanomaterial clusters such as titanium dioxide (TiO2) and zinc oxide (ZnO). The nanomaterials are fixed by organic long-chain polymers, forming a flexible and foldable composite layer. The flexible fibrous substrate, such as non-woven fabric, is inherently elastic; after being superimposed with the porous structure of nanoclusters, it can undergo localized deformation under pressure or airflow, dynamically adjusting the pore distribution and enhancing the metal powder capture efficiency. It should also be noted that after filter layer 7 adsorbs metal powder, some metal powder is captured by filter layer 7, but when metal powder accumulates on filter layer 7, it becomes difficult to capture. Therefore, the uncaptured metal powder can move into the deformation layer 71. Furthermore, under negative pressure, the positioning shell 2 always faces inwards, making it difficult for even locally dispersed metal powder to move outwards from the positioning shell 2, ensuring metal powder collection and preventing environmental impact.

[0057] like Figure 3 and Figure 4 The negative pressure generating part includes a support disk 4 and an adsorption layer 5;

[0058] The support plate 4 is fixed on the upper end of the grinding base 1, and its upper end is fixed to the positioning shell 2. A processing cavity 41 is formed inside. A chamber is formed between the support plate 4 and the positioning shell 2. The lower inner wall of the processing cavity 41 has a through suction port 43.

[0059] The adsorption layer 5 is fixed to the lower end of the support plate 4, and a connecting pipe 51 connected to the air pump is connected to the outside to generate negative pressure on the adsorption port 43.

[0060] Specifically, there are several adsorption ports 43 distributed along the circumference of the support disk 4. The lower ends of all adsorption ports 43 are connected to the adsorption layer 5. When a negative pressure is generated, the fluid is dispersed into finer streams as it passes through, avoiding excessively high local flow velocities or turbulence. The adsorption ports 43 disperse the concentrated suction force over a larger area, preventing excessive local stress from causing deformation or damage to the filter layer 7. The negative pressure, through suction, forces the airflow containing metal powder through the filter layer 7, where the metal powder is trapped due to inertia or diffusion effects. The higher the negative pressure, the higher the adsorption efficiency. It is necessary to balance energy consumption and the resistance of the filter layer 7. The negative pressure generated by the air pump on the filter layer 7 is typically between -10 kPa and -60 kPa, which can be adjusted by those skilled in the art according to the specific equipment type and application scenario.

[0061] like Figures 5-7 As shown, Figure 6 To restore the bent rod 63 to its original state. Figure 7 The dashed line represents the bent rod 63 extending downwards and into the adsorption port 43. The metal frame 6 includes two inner and outer ring frames 61 and multiple crossbars 62.

[0062] The inner wall of the processing cavity 41 is fixed with a clamping ring 42, and the two clamping rings 42 are clamped on the two circle frames 61.

[0063] A plurality of cross bars 62 are fixed between the two circle frames 61 and are distributed in a circle, the middle section of the cross bar 62 is integrally formed with the bent bar 63, and the cross bar 62 and the bent bar 63 extend downward into the suction port 43 under negative pressure and move out of the suction port 43 to generate shaking when rotating.

[0064] Specifically, the clamping ring 42 on the inner wall of the processing cavity 41 supports the two circle frames 61, the two circle frames 61 are sleeved, and the plurality of cross bars 62 are connected between the two circle frames 61 to form the metal frame 6. It should be noted that the two circle frames 61 are clamped on the inner and outer clamping rings 42, the outer side of the outer circle frame 61 is constrained, the inner side of the inner circle frame 61 is constrained, and the anti-deformation ability is significantly improved. The material of the two circle frames 61 is steel.

[0065] The bent bar 63 is in the shape of "V", the cross bar 62 and the bent bar 63 are both elastic, the upper end of the suction port 43 is a circular arc transition, and only the cross bar 62 and the bent bar 63 deform under the action of negative pressure. The material of the cross bar 62 and the bent bar 63 is spring steel. In addition, it should be noted that the lower end of the bent bar 63 "V" shape will move downward under the action of negative pressure and produce extrusion with the lower end of the processing cavity 41, and will also pass through the suction port 43 during rotation, so that the lower end of the bent bar 63 "V" shape extends into the suction port 43, changes the deformation state of the cross bar 62 and the bent bar 63, and changes the state of the filter layer 7 and the deformation layer 71. When the bent bar 63 passes through the suction port 43, shaking occurs. The above two conditions make the metal powder on the filter layer 7 concentrate in the deformation layer 71. It should be noted that the edge of the circular suction port 43 is a circular arc transition, and the bent bar 63 will not produce abrupt shaking when passing through, so that the movement is smoother, and the metal powder is prevented from being raised.

[0066] The number of corresponding suction ports 43 in the circumferential direction is the same as the number of bent bars 63, and the positions are opposite, so that each bent bar 63 can move into the corresponding suction port 43 during rotation, so that the filter layer 7 and the deformation layer 71 are deformed and shaken, and the concentration of metal powder is accelerated.

[0067] The filter layer 7 is in the shape of a circle, the cross section of the deformation layer 71 is in the shape of "V", and the upper end of the bent bar 63 is attached. The inner and outer edges of the filter layer 7 are fixed with the two circle frames 61 to prevent the whole filter layer 7 from moving.

[0068] The part where the deformation layer 71 and the filter layer 7 are overlapped has multiple folds, the deformation layer 71 is equidistant from the inner diameter and the outer diameter of the filter layer 7, under the action of negative pressure, the deformation layer 71 moves downward, the filter layer 7 is stretched, the folds make the filter layer 7 tilt downward, which can produce deformation and avoid the filter layer 7 being torn, the deformation layer 71 is equidistant from the inner diameter and the outer diameter of the filter layer 7, which is to keep the part of the filter layer 7 on both sides of the deformation layer 71 tilted, collect metal powder, after the filter layer 7 is deformed under negative pressure, metal powder will also exist in the folded part, but in the case of shaking, the accumulation can be reduced as much as possible, so it will not affect the recovery of the folds.

[0069] As shown in Figure 8 The transmission part 8 includes an outer shaft 81, an inner shaft 82 and a planetary gear set;

[0070] The outer shaft 81 is fixed with the grinding seat 1;

[0071] The inner shaft 82 penetrates the outer shaft 81 and is fixed with the output end in the grinding seat 1, and the outer end of the inner shaft 82 is detachably fixed with the grinding wheel 3;

[0072] The planetary gear set is installed on the outer shaft 81 and is used for transmission connection between the inner shaft 82 and the metal frame 6.

[0073] It should be noted that the inner shaft 82 is connected with the motor output end to drive the grinding wheel 3 to rotate, and the outer side of the inner shaft 82 drives the metal frame 6 to rotate through the planetary gear set, the planetary gear set achieves the effect of speed reduction, avoiding that the metal frame 6 rotates too fast to affect the adsorption of metal powder on the filter layer 7.

[0074] The planetary gear set includes a sun gear 83, a planet gear 85 and a ring gear 84;

[0075] The sun gear 83 is fixedly sleeved with the inner shaft 82;

[0076] The planet gear 85 is engaged with the sun gear 83 and is located on the upper end of the outer shaft 81, the upper end of the planet gear 85 is clamped with a planet carrier 86, the outer side of the planet carrier 86 is fixed with a connecting rod 64 which is detachably fixed with the metal frame 6, the connecting rod 64 is used to fix the inner and outer ring frames 61 and avoid the deformation of the ring frame 61, and simultaneously drive the ring frame 61 to rotate;

[0077] The ring gear 84 is integrally formed on the upper end of the outer shaft 81 and is engaged with the planet gear 85 on the inner side.

[0078] The grinding wheel speed of the milling cutter grinding machine varies with the specific model and purpose, but the grinding wheel speed of the ordinary milling cutter grinding machine is concentrated in the range of 4400-6000 rpm, so the speed of the metal frame 6 and the filter layer 7 is too high, and the planetary gear set can greatly reduce the speed of the metal frame 6 and the filter layer 7, avoiding the dispersion of the concentrated metal powder outward. It should be noted that the planetary gear set can be adjusted according to the required speed, and can be configured as a multi-stage planetary gear set to reduce the speed.

[0079] In addition, it should be noted that during the high-speed rotation of the grinding wheel 3, the metal powder generated due to centrifugal force does not move inward to the planetary gear set.

[0080] As shown in Figure 9 is a partial top view of the filter layer 7, which includes a filter inner layer 701 and a filter outer layer 702, and a deformation layer 71 is integrally arranged between the filter inner layer 701 and the filter outer layer 702. The outer ends of the filter inner layer 701 and the filter outer layer 702 are fixed with the inner and outer rings 61, respectively. The filter layer 7 is divided into two layers, which are connected by the deformation layer 71, to form a complete circle. The distance between the deformation layer 71 and the edges of the filter inner layer 701 and the filter outer layer 702 is equal. When the filter layer 7 is deformed by negative pressure, the deformation layer 71 is located at the lowermost end, and the filter inner layer 701 and the filter outer layer 702 on the inner and outer sides are inclined towards the deformation layer 71. The inclination state is similar, and the metal powder accumulated on the filter inner layer 701 and the filter outer layer 702 moves along the inclined surface to the deformation layer 71;

[0081] The folds include inner folds 703, outer folds 704 and fold connecting parts 705. The inner folds 703 and the outer folds 704 are located on the filter inner layer 701 and the filter outer layer 702, respectively. The inner folds 703 and the outer folds 704 extend towards the deformation layer 71. The fold connecting parts 705 are located on the surface of the deformation layer 71, and their two ends are connected with the inner folds 703 and the outer folds 704, respectively. When the filter layer 7 is deformed by negative pressure, the inner folds 703 and the outer folds 704 are in a state of extrusion and stretching, respectively. One side of the "V" shape of the fold connecting part 705 is also extruded, and the other side is stretched. It should be noted that when the filter layer 7 is deformed, the inner folds 703 are extruded, the outer folds 704 are stretched, and the fold connecting part 705 inside the deformation layer 71 is stretched on the outside and extruded on the inside. The part of the fold that is extruded on the inside will be deformed to be concave or convex. During the rotation of the filter layer 7, the deformation position of the fold connecting part 705 will be clamped with the metal powder inside the deformation layer 71. Even if the metal powder accumulates inside the deformation layer 71, it will not produce a large displacement during the rotation of the filter layer 7, reducing the dispersion of the metal powder.

[0082] The working principle of the present application: when the milling cutter is ground by the milling cutter grinder, it needs to be in contact with the grinding wheel 3 and generate metal powder. Therefore, the metal powder needs to be treated. Under the action of the air pump on the outside, negative pressure is generated inside the adsorption layer 5, the multiple adsorption ports 43 generate adsorption airflow effect, the outside of the treatment cavity 41 is blocked by the adsorption layer 5, and the overall generated airflow enters from the positioning shell 2 and then moves out from the connecting pipe 51. The metal powder moves with the airflow and is filtered by the adsorption layer 5.

[0083] Based on the above description, the generated negative pressure stretches the filter layer 7 downward. Since the metal frame 6 has elasticity and has a bending rod 63, the filter layer 7 has wrinkles and has a deformation layer 71. The deformation layer 71 of the filter layer 7 moves downward and expands, causing the parts of the filter layer 7 on both sides of the deformation layer 71 to tilt towards the deformation layer 71. The metal powder adsorbed by the filter layer 7 and the deformation layer 71 can be concentrated as much as possible inside the deformation layer 71, reducing the impact on the filtering effect of the filter layer 7. Then, under the action of the metal frame 6 returning to its original position without negative pressure, the filter layer 7 and the deformation layer 71 return to their original positions. The deformation layer 71 clamps the metal powder to prevent it from flying during subsequent operations.

[0084] In addition, after the metal powder is relatively concentrated, the filter layer 7 can continue to maintain filtering at other positions. Even if the filtering effect is reduced, there is still a filtering effect, which will not directly affect the filtering effect, and there is no need to accurately control the replacement time.

[0085] Through the transmission part 8, the metal frame 6 and the filter layer 7 rotate while the grinding wheel 3 is rotating and grinding. Under the action of negative pressure, the bending rod 63 moves downward and deforms. The end of the bending rod 63 passes through the adsorption port 43 and can extend into the adsorption port 43. Therefore, the metal frame 6 continuously moves into and out of the adsorption port 43 during rotation, achieving intermittent shaking. The filter layer 7 also achieves intermittent shaking, and the filter layer 7 and the deformation layer 71 "V" state produce a dynamic change, which can continuously concentrate the generated metal powder into the deformation layer 71 for further concentration. It should be noted that the shaking under the action of negative pressure does not cause the metal powder to fly.

[0086] The planetary gear set stabilizes the rotation speed of the metal frame 6 and the filter layer 7, avoiding the metal powder flying outward due to excessive rotation speed.
