Description

Technical Field

[0001] This utility model relates to the field of machining tool technology, and in particular to a magnetic quick clamping structure for blade positioning. Background Technology

[0002] In the field of machining tools, magnetic adsorption quick clamping structures for insert positioning can quickly fix the insert in a designated position and ensure stable positioning accuracy during machining. They are widely used in various cutting equipment such as lathes and milling machines, effectively improving the efficiency and quality of machining.

[0003] Currently, some mechanically clamped tool holders typically consist of a tool holder body, clamping bolts, positioning blocks, and other components. Their working principle is to tighten the clamping bolts, using the cooperation between the bolts and the positioning blocks to firmly clamp the cutting tool onto the tool holder, thus fixing the cutting tool. Some vacuum adsorption clamping devices include a vacuum generator, an adsorption plate, and seals. During operation, the vacuum generator creates a negative pressure inside the adsorption plate, and atmospheric pressure is used to adsorb and fix the cutting tool onto the adsorption plate, completing the clamping of the cutting tool. All these devices can achieve the clamping and fixing of cutting tools, ensuring the normal operation of cutting processes.

[0004] In existing technologies, some fully automatic tool grinding machines have significant shortcomings in tool clamping. Most rely on magnetic force to fix the tool in a clamping structure, lacking a dedicated tool clamping mechanism. When performing high-intensity cutting, the tool is prone to loosening or displacement due to the large cutting force, resulting in decreased tool positioning accuracy and affecting the dimensional accuracy and surface quality of the machined parts. Similarly, there are deficiencies in cleaning and filtration. Existing clamping structures lack corresponding cleaning and filtration mechanisms, allowing metal shavings and cutting fluid impurities generated during processing to easily accumulate at the bottom, severely shortening the tool's service life. Therefore, a magnetic quick-clamping structure for tool positioning is proposed to solve these problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 3 , Figure 4 This utility model provides an embodiment of a magnetic quick-clamping structure for blade positioning, comprising a housing 1. Fixing plates 2 are fixedly connected to the front and rear sides of the housing 1. The fixing plates 2 are parallel and symmetrically distributed, providing a stable support foundation for the installation of various components. A fixing ring 3 is threadedly connected to the top of the fixing plate 2. The fixing ring 3 provides a stable mounting point for the fixing tube 4, ensuring that the fixing tube 4 will not shift during operation. The fixing tube 4 is threadedly connected to the inside of the fixing ring 3. The fixing tube 4 organically connects the fixing plate 2 to the subsequent connecting tube 5, playing a role in force transmission and structural extension. The rear side of the fixing tube 4 is fixed... A connecting pipe 5 is fixedly connected to the magnetic suction plate 6, which is crucial for activating the magnetic suction plate 6. The magnetic suction plate 6 is fixedly connected to the top of the connecting pipe 5 to attract the blade. Multiple springs 8 are installed at the top of the connecting pipe 5, acting as buffers and shock absorbers to prevent damage to other components due to severe vibration. A clamp 7 is fixedly connected to the top of the springs 8, clamping and securing the blade to prevent loosening or detachment during equipment operation, ensuring stable operation. A pressing mechanism 9 is fixedly connected to the top of the clamp 7, providing continuous and stable pressure to further enhance the clamping force and ensure more reliable clamping performance.

[0035] A self-cleaning filter mechanism 10 is fixedly connected inside the outer casing 1. This mechanism filters and purifies the medium flowing inside the equipment, removing impurities and contaminants. It also automatically cleans and maintains itself, preventing filter clogging from affecting normal operation, extending the equipment's lifespan, and ensuring high efficiency. The clamping mechanism 9 includes a clamping column 91, the bottom of which is fixedly connected to the top of the clamp 7. This column is the force-bearing component of the clamping mechanism 9, transmitting pressure from subsequent components to the clamp 7. A rotating block 92 is rotatably connected to the bottom of the clamping column 91, allowing it to rotate around the connection point with the clamping column 91. The rotating block 92, also known as the pressure block 91, is used to adjust the direction of force transmission. A rotating column 93 is rotatably connected to the bottom of the pressure column 91. The rotating column 93 and the rotating block 92 work together to transmit and adjust the direction of force, enhancing the flexibility and adaptability of the pressure mechanism 9. A rotating port 94 is rotatably connected to the bottom of the rotating block 92. The rotating port 94 can rotate at multiple angles according to the force applied, further optimizing the force transmission path and ensuring that the pressure is accurately and effectively applied to the support plate 95. The support plate 95 is fixedly connected to the bottom of the rotating port 94. As a load-bearing component, the support plate 95 concentrates the force transmitted from above and evenly transmits it to the cylinder assembly 96 below. It also provides a stable mounting platform for components such as the rotating port 94.

[0036] A cylinder assembly 96 is fixedly connected to the bottom of the support plate 95. The cylinder assembly 96 is the power source of the clamping mechanism 9, generating driving force and transmitting it to the clamping jaws 7 through a transmission component to achieve the clamping operation of the component. The cylinder assembly 96 includes a push rod 961, which is the actuating component of the cylinder assembly 96. Under the action of the internal pressure of the cylinder, it can perform linear reciprocating motion, directly transmitting the force generated by the cylinder to the support plate 95. The top of the push rod 961 is fixedly connected to the bottom of the support plate 95, and the bottom of the push rod 961 is fixedly connected to an upper end cover 962. The upper end cover 962 and the cylinder barrel 964 cooperate to form a sealed cavity to prevent gas leakage inside the cylinder, ensuring that the cylinder can generate pressure normally, and also providing an installation position for the pull rod 963. Multiple pull rods 963 are fixedly connected to the bottom of the upper end cover 962. The two ends of the pull rods 963 are connected to the upper end cover 962 and the lower end cover 965 respectively, which plays a role in connection and fixation, ensuring the relative position between the upper end cover 962 and the lower end cover 965 is stable, and enhancing the overall structural strength of the cylinder assembly 96. The cylinder barrel 964 is fixedly connected to the bottom of the upper end cover 962. The cylinder barrel 964 is the main structure of the cylinder assembly 96, which houses the piston and other components and provides space for the movement of the push rod 961. The lower end cover 965 is fixedly connected to the bottom of the cylinder barrel 964. The lower end cover 965 and the upper end cover 962 work together to seal the two ends of the cylinder barrel 964, ensuring that effective pressure can be built up inside the cylinder, and also providing support and protection for the cylinder barrel 964.

[0037] Reference Figure 3 and Figure 5The self-cleaning filter mechanism 10 includes a support baffle 101, which is externally fixedly connected to the inside of the housing 1. The support baffle 101 is the basic support component of the self-cleaning filter mechanism 10, providing a stable mounting platform for other components such as the cleaning scraper 102 and the water tank 108. The cleaning scraper 102 is slidably connected to the top of the support baffle 101, and the cleaning scraper 102 can reciprocate on the top of the support baffle 101. Its main function is to scrape and clean the surface of the support baffle 101. A guide post 103 is fixedly connected inside the cleaning scraper 102, which provides guidance for the sliding of the cleaning scraper 102, ensuring that the cleaning scraper 102 can slide along a set path. The guide post 103 has a fixed bottom connection to a movable knob 104, which cooperates with a lead screw 105. When the lead screw 105 rotates, the movable knob 104 can move along the axial direction of the lead screw 105, thereby driving the cleaning scraper 102 to slide through the guide post 103. The bottom of the movable knob 104 is slidably connected to the lead screw 105, which can rotate under the drive of the motor 106. Through the threaded engagement with the movable knob 104, the rotational motion is converted into the linear motion of the movable knob 104, thus providing power for the sliding of the cleaning scraper 102.

[0038] A second motor 106 is fixedly connected to the rear side of the lead screw 105. The second motor 106 is the power source for the self-cleaning filter mechanism 10, and can output rotational power to drive the lead screw 105 to rotate. The drive end of the second motor 106 is fixedly connected to the rear side of the lead screw 105. A protective shell 107 is fixedly connected to the outside of the second motor 106. The protective shell 107 encloses the second motor 106, which can effectively prevent external dust, moisture, impurities, etc. from corroding the motor. At the same time, it can also reduce the noise generated by the motor during operation, protect the motor, and extend the service life of the motor. A water tank 108 is fixedly connected to the front side of the support baffle 101. The water tank 108 provides a temporary storage space for water. A filter screen 109 is detachably connected inside the water tank 108. When materials such as iron filings flow through the filter screen, they can be intercepted and filtered out. There is a hidden diamond-shaped buckle at the bottom, which is connected to the groove of the water tank 108. The top of the filter screen 109 is threaded with a connecting handle 1010. The connecting handle 1010 provides a convenient operating part for the removal and installation of the filter screen 109. When the filter screen needs to be cleaned, replaced or maintained, the operator can easily take the filter screen out of the water tank 108 or install it by holding the connecting handle 1010, which simplifies the operation process and improves maintenance efficiency.

[0039] Reference Figures 1 to 3The bottom of the fixing ring 3 is threadedly connected to the top of the fixing plate 2.

The control console 12 is the operation control center of the equipment, integrating various control and display components. A data display screen 13 is fixedly connected to the front of the control console 12. The data display screen 13 is used to display various operating parameters of the equipment and the switches of other structures in real time. A lifting disc 14 is rotatably connected to the front of the control console 12. By rotating the lifting disc 14, the lifting and lowering of the whetstone 28 can be controlled. Limit switches 15 are fixedly connected to both the left and right ends of the front of the control console 12. These two limit switches 15 correspond to the two extreme positions of the movement trajectory of the control console 12. A contact strip 16 is rotatably connected to the bottom of each limit switch 15. The contact strip 16 is the trigger component of the limit switch 15; one end is rotatably connected to the limit switch 15, and the other end can swing freely. A connecting rod 17 is fixedly connected to the front side of the housing 1. The connecting rod 17 is horizontally fixed to the housing 1, providing a carrier for the installation and sliding of the control rings 18.

A slider 19 is fixedly connected to the right side of the control console 12. The slider 19 cooperates with other corresponding guide rails or grooves to assist the control console 12 in sliding.

[0040] A connecting plate 20 is threadedly connected to the rear side of the control console 12. The connecting plate 20 is firmly fixed to the control console 12 by the threaded connection. Its main function is to provide a stable mounting base for the motor 21. The motor 21 is fixedly connected to the rear side of the connecting plate 20. The motor 21 is the power source for the sharpening stone 28 in the equipment. A connecting block 22 is fixedly connected to the rear side of the control console 12. The connecting block 22 is the mounting carrier for the water spray pipe 23 and the water outlet pipe 25, and plays a role in connection and fixation. The water spray pipe 23 is fixedly connected to the left and right ends of the front side of the connecting block 22. One end of the water spray pipe 23 is connected to the water flow channel inside the connecting block 22, and the other end is provided with a water nozzle. A fixing block 24 is fixedly connected to the outside of the water spray pipe 23. The fixing block 24 further fixes the water spray pipe 23 to the control console 12, enhancing the installation firmness of the water spray pipe 23. A water outlet pipe 25 is fixedly connected to the rear side of the connecting block 22. The water outlet pipe 25 connects the water pump 26 and the connecting block 22. The water supply pipe has an internal water flow channel. A water pump 26 is fixedly connected to the bottom of the outlet pipe 25. The water pump 26 is the power unit of the water spray system. A suction pipe 27 is fixedly connected to the output end of the water pump 26. One end of the suction pipe 27 is connected to the water pump 26, and the other end extends into the water source. A whetstone 28 is fixedly connected to the drive end of the motor 21. The whetstone 28 rotates at high speed under the drive of the motor 21, and uses its surface grinding performance to grind tools or other workpieces. A connecting column 29 is fixedly connected inside the outer shell 1. The connecting column 29 is vertically fixed inside the outer shell 1, providing an installation position and support for the magnetic switch 30. The magnetic switch 30 is fixedly connected inside the connecting column 29. The magnetic switch 30 is a switch device controlled by magnetic principle. Bases 31 are fixedly connected to the front and rear sides of the bottom of the outer shell 1. The bases 31 are symmetrically distributed on the front and rear sides of the bottom of the outer shell 1 and serve as the supporting foundation for the entire equipment.

[0041] Working principle: Place the blade to be sharpened onto the magnetic plate 6, and it will be held in place by the clamp 7 without falling. Then, activate the magnetic plate 6 in the control panel 12, and the blade will be attracted by a strong magnetic force. Then, activate the clamping mechanism 9, and the push rod 961 in the cylinder assembly 96 will be pulled down, causing the support plate 95 and the rotating port 94 to move down. This causes the rotating block 92 to rotate down, and the clamping column 91 will be pulled down around the rotating column 93 due to the tension, thereby pressing the clamp 7. The clamp 7 clamps the blade because the rotating column 93 is moving down.

[0042] When motor 21 is started in console 12, it causes the whetstone 28 to rotate. The rotating lifting disc 14 causes the whetstone 28 to move downward to begin sharpening the blade. At this time, the slider 19 is activated, and the entire console 12 will slide along the slide groove 11. When the console 12 slides on the slide groove 11 to a certain extent, the contact bar 16 will touch the control ring 18 due to the sliding of the console 12. The limit switch 15 transmits a signal to the slider 19 due to the contact of the contact bar 16, and the console 12 will start to slide in the opposite direction, thereby evenly sharpening the entire blade.

[0043] During the grinding process, a large amount of heat is generated, which can damage the blade. At this time, the water pump 26 will draw water from the water tank 108 and then transmit it to the connecting block 22 through the water outlet pipe 25. The connecting block 22 will then send water to the water spray pipe 23, which will spray water onto the whetstone 28 and the blade to achieve the effects of lubrication and cooling. The sprayed water will pass through the support baffle 101 and flow back into the water tank 108 through the small hole, achieving the effect of recycling.

[0044] During the sharpening of the blades, iron filings and other materials fall onto the support baffle 101. After sharpening, the second motor 106 is started, which drives the lead screw 105 to rotate. The movable knob 104 moves back and forth in the groove of the lead screw 105 due to the rotation of the lead screw 105, thereby causing the guide post 103 and the cleaning scraper 102 connected to the movable knob 104 to slide and clean the support baffle 101. The cleaned iron filings and other materials are pushed onto the filter screen 109. Then, the filter screen 109 is lifted using the connecting handle 1010 to pour out the iron filings and other materials, and then placed on the water tank 108, thus achieving recycling.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
