Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of angle grinders, in particular to a self-cleaning metal cutting angle grinder based on centrifugal chip throwing. BACKGROUND

[0002] In the field of metal processing, angle grinders are widely used in the processing of metal materials such as steel and aluminum as a high-efficiency cutting and grinding tool. Through the contact between the high-speed rotating grinding disc or cutting disc and the metal surface, the angle grinder can achieve cutting and grinding of the metal. However, during the grinding operation of the angle grinder, a large amount of metal chips will be generated. These chips are hard and fly at high speed. If not effectively controlled, they will not only pose a threat to the personal safety of the operator, but also affect the cleanliness of the work environment. In addition, the accumulation of chips on the equipment will also affect the normal operation and service life of the angle grinder.

[0003] Some existing angle grinders do not have protective covers, which poses significant safety hazards and operational drawbacks during metal cutting and grinding operations. Firstly, under the action of the high-speed rotating grinding disc or cutting disc, metal chips will fly at high speed in all directions. Without the protection of a protective cover, these chips can easily hit the operator's body, especially the face, eyes and other vulnerable parts, causing scratches, burns or even more serious injuries, posing a direct threat to the operator's personal safety. Secondly, the flying chips will scatter irregularly in the work environment, not only polluting the surrounding equipment, tools and ground, increasing the subsequent cleaning workload, but also entering the gaps or interiors of other mechanical equipment, affecting their normal operation, and even causing equipment failure. Thirdly, in addition to metal chips, a large amount of metal dust will also be generated during the grinding process. Without the protection of a protective cover, these dusts will directly spread into the air and be inhaled by the operator, which will seriously damage the respiratory system over a long period of time and does not meet the requirements of occupational health and safety.

[0004] On the other hand, the angle grinder has obvious shortcomings in debris processing. Firstly, the metal debris generated by polishing will accumulate on the surface of the grinding disc, the key components of the equipment and the vicinity of the working area. The debris accumulated on the surface of the grinding disc will increase the rotational resistance of the grinding disc, causing the rotational speed of the grinding disc to decrease, reducing the efficiency of cutting and polishing, and also causing uneven stress on the grinding disc, accelerating the wear of the grinding disc, shortening its service life and increasing the frequency and cost of replacing the grinding disc. Secondly, the accumulated debris needs to be cleaned manually by the operator frequently, which not only interrupts the continuity of the work and reduces the overall work efficiency, but also increases the labor cost. In addition, due to the lack of centrifugal force, the debris cannot be orderly guided and discharged, and part of the debris will randomly scatter inside the protective structure, or even overflow from the gap of the protective structure, again polluting the working environment, and it is also difficult to collect and recycle the debris, which does not meet the concept of energy saving and environmental protection. Moreover, the random accumulation of debris will also affect the heat dissipation performance of the angle grinder, causing the internal temperature of the equipment to rise, affecting the performance and service life of the core components such as the motor.

[0005] Therefore, a self-cleaning metal cutting angle grinder based on centrifugal debris throwing is proposed to solve the above problems. SUMMARY

[0056] The plurality of semicircular grooves in the regulating groove 23 and the magnets are mainly used in cooperation with the regulating ring 41 to adjust the inclination angle of the flow guide vane 37.

[0057] The flow guide vane 37 is mainly used for guiding the debris generated when the main body 11 of the angle grinder works.

[0058] The debris throwing opening 32 is used for the flow of the debris to the collection cavity 24 for storage and collection.

[0059] ​The working principle of all the above embodiments is as follows:

[0060] Initial state: the collecting cavity 24 is not installed on the angle grinder body 11, and the angle grinder body 11 has not started working.

[0061] The working process of the first assembly is as follows:

[0062] In use, the collecting cavity 24 is clamped to the inner bottom of the baffle 21, the clamping block 25 is aligned with the bottom of the inner slot 22, and then the collecting cavity 24 is pushed up along the sliding groove of the inner slot 22, the clamping block 25 slides in the sliding groove of the inner slot 22, and slides into the magnetic attraction chamber at the top until the clamping block 25 is attracted and positioned in the magnetic attraction chamber at the top end of the inner slot 22, so as to clamp the collecting cavity 24 to the baffle 21, and prepare for the subsequent collection of debris;

[0063] The above working process is described in detail in the following Figures 1 to 5 .

[0064] The working process of the second assembly and the third assembly is as follows:

[0065] In use, the motor shaft 14 is started, the grinding disc 15 rotates to grind the material, the baffle 21 is arranged to protect the debris generated during grinding, prevent the debris from splashing, and protect the safety of the operator, and according to different specifications of the grinding disc 15 in use, the contact position and angle of the surface of the grinding disc 15 with the debris are different, and the angle of the guide vane 37 is adjusted to keep the guide vane 37 at a more suitable angle with the surface of the grinding disc 15 to better guide the debris, and the specific implementation is as follows:

[0066] The operator manually controls the control base 43 to move away from the operator, and the movement of the control base 43 makes the control ring 41 fixedly connected thereto rotate in the positive direction, and when the control ring 41 rotates in the positive direction, the synchronous column 42 fixedly connected to the outer circle of the control ring 41 synchronously deflects in the positive direction, so that the deflection of the synchronous column 42 promotes the control body 38 sleeved on the outer circle of the synchronous column 42 to deflect in the reverse direction with the synchronous column 42 as the axis, and under the fixed connection between the control body 38 and the positioning tube 36, the deflection of the control body 38 makes the positioning tube 36 rotate in the reverse direction with the positioning hole 35 as the axis, the guide vane 37 fixedly connected to the positioning tube 36 deflects in the reverse direction with the center of the positioning tube 36 as the axis, and then deflects in the oblique direction upward with the positioning tube 36 as the axis, the end of the guide vane 37 away from the positioning tube 36 rotates in the sleeve tube 39, and is stably deflected under the limiting of the sleeve tube 39, and the farther the synchronous column 42 is moved, the larger the inclination angle of the guide vane 37 is;

[0067] When deflected to the desired angle, the synchronization column 42 is clamped into the corresponding semicircular groove on the regulating groove 23. The specific implementation is as follows:

[0068] When the regulating column 45 is adjusted, the regulating column 45 is connected with the regulating base 43 through the sliding block 46. Under the clamping force, the adjustment of the regulating column 45 by the operator is transmitted to the regulating base 43, so that the regulating ring 41 rotates. When adjusted to the desired position, the operator moves the regulating column 45 transversely, so that it slides in the T-shaped groove 44 to the eccentric position of the regulating base 43, and then clamps with the semicircular groove on the regulating groove 23. The material of the regulating column 45 cooperates with the magnet in the semicircular groove of the regulating groove 23 to limit the regulating column 45 and maintain the state of angle adjustment.

[0069] Further, when the debris is generated during the operation of the grinding disc 15, the centrifugal force generated by the rotation of the grinding disc 15 gives the debris an initial moving force, and then the debris is thrown into the baffle 21. Under the setting of the guide vane 37, the debris is guided to move along the inclined direction of the guide vane 37, and through the opening of the debris throwing port 32, the debris is transferred to the collecting cavity 24 for collection.

[0070] Through the setting of the first assembly, the clamping block 25 cooperates with the structure of the inner groove 22 to realize the quick assembly of the collecting cavity 24 and the baffle 21 without complex work and simple operation. The preparatory work before collecting debris can be completed in a short time, the operation preparation efficiency is improved, and the stability of the collecting cavity 24 during high-speed operation of the angle grinder main body 11 is ensured under the clamping and magnetic attraction of the inner groove 22 and the clamping block 25, avoiding the situation of loosening and falling off, and avoiding the displacement of the collecting cavity 24 caused by equipment vibration, which affects the debris collection effect, and ensures the stability of the debris protection of the baffle 21.

[0071] Through the setting of the guide vane 37, the centrifugal force generated by high-speed rotation is guided to make the originally chaotic and splashing metal debris move along the preset trajectory, avoiding the random scattering or accumulation of the debris on the cutting blade, main shaft and other key components, reducing the equipment wear caused by the winding or jamming of the debris, and prolonging the service life of the angle grinder. Secondly, by optimizing the angle of the guide vane 37, the debris can be accurately guided to the collecting cavity 24, realizing the centralized collection of the debris, reducing the pollution of the working environment, reducing the workload of the subsequent cleaning of the operator, and improving the operation continuity. In addition, the guide vane 37 cooperates with the baffle 21 to form a relatively closed guide space, which can further block part of the debris from splashing outward, enhance the safety protection of the operator, and especially reduce the harm of fine dust and debris to the respiratory tract and eyes of the human body.

[0072] Through the setting of the second assembly, cooperating with the third assembly, the adjustment of the dialing distance of the regulating base 43 adjusts the deflection amplitude of the flow guide vane 37, so that the flow guide vane 37 uses the positioning pipe 36 as the shaft center and cooperates with the sleeve limiting pipe 39 to limit the angle adjustment. Under the angle adjustment of the flow guide vane 37, the flow guide angle is optimized for different specifications of the grinding disc 15 and different materials of the debris, so as to ensure that the flow guide vane 37 and the grinding disc 15 surface form a suitable guide path, avoid the accumulation of debris at the flow guide vane 37 or the failure of the flow guide, and improve the directivity and collection rate of the centrifugal debris throwing; the angle of the flow guide vane 37 can also be adjusted according to the speed change of the angle grinder main body 11: the speed of the angle grinder main body 11 fluctuates under different working conditions, when the speed is high, the centrifugal force of the debris is large, and the angle of the flow guide vane 37 is adjusted to guide the debris to enter the collection cavity 24 more smoothly; when the speed is low, the angle is adjusted to enhance the pushing effect of the flow guide vane 37 on the debris, so as to ensure that the debris can be effectively collected under different speeds and improve the overall self-cleaning effect.

[0073] Through the setting of the third assembly, after the adjustment is completed, the regulating column 45 is clamped into the semicircular groove of the regulating groove 23, cooperates with the magnet limiting, can stably maintain the adjustment angle of the flow guide vane 37, avoids the angle deviation caused by vibration when the angle grinder main body 11 works, ensures the continuous and reliable flow guide effect, and realizes the angle adjustment by manually dialing the regulating base 43. The regulating column 45 is transversely moved to cooperate with the regulating base 43 to complete the locking, without the need for additional work, the operation of the bare machine is simple, the flow guide angle can be quickly switched during work, the downtime adjustment time is reduced, and the continuous work efficiency is improved.
