[0001] The present invention relates to the technical field of polishing devices, and particularly to a surface uniform fine polishing device for agate production. Background Art

It is translucent or opaque. The original form is trigonal system. It often forms various structures in a dense massive form, such as mammillary, grape-like, nodular, etc., and the common one is concentric structure. Chalcedony with different colors usually has multiple colors such as green, red, yellow, brown, white, etc. It is commonly used as a plaything, ornamental object, ornament or plaything. Strings of agate balls can often be seen in ancient funerary objects. During the processing of agate, it is necessary to polish its surface to improve its aesthetics, and a polishing device is required for this; After retrieval, the publication number is CN214418491U, which discloses "a surface uniform fine polishing device for agate production. Above the machine base, a portal frame is fixed. At the top center position of the portal frame, a polishing electric telescopic rod is inserted and fixed. The telescopic end of the polishing electric telescopic rod is fixed with a polishing motor. The rotating shaft end of the polishing motor is fixed with a buffer rod mechanism, and one end of the buffer rod mechanism is fixed with a polishing disc. On both sides of the portal frame, two workpiece clamping and fixing mechanisms with the same structure are symmetrically arranged. Through the workpiece clamping and fixing mechanism, this application can simply and quickly fix the agate product, improve stability, and prevent vibration during polishing".
[0003] The above patent also has the following defects: This application lacks a systematic cooling design, which will cause local overheating of the agate, and it is easy to generate high temperatures at the polishing points, which will in turn cause irreversible damages such as microcracks and phase change and devitrification, greatly reducing the production quality and production efficiency, significantly increasing the production cost, and not meeting the production requirements.
[0004] Therefore, it is urgent to improve the polishing device to solve the above problems. Summary of the Invention
[0005] The purpose of the present invention is to provide a surface uniform fine polishing device for agate production. Through a single drive source to link the rotation of the polishing head, the generation of cooling air flow and the anti-precipitation stirring of the coolant, and integrating a mechanical pressure-triggered cooling system, it realizes the efficient coordination of the whole process of polishing and cooling, significantly reduces the equipment cost and energy consumption. Moreover, when the air flow generated by the fan passes through the throat pipe, the coolant is atomized into tiny droplets by using the Venturi effect, significantly increasing the contact area between the coolant and the polishing area, accelerating heat exchange, and improving the cooling efficiency.
[0006] To achieve the above object, the main technical solution adopted by the present invention includes a polishing device for polishing agate, and the polishing device is composed of a machine shell, a transmission component, a driving structure and a polishing head; A connecting frame is arranged on the machine shell, and the connecting frame is respectively provided with an intermittent structure connected to the transmission component, a first driving component cooperating with the intermittent structure by a second driving component, and a temperature reduction structure mounted on the connecting frame; The transmission component includes a transmission sleeve and a transmission shaft connected by splines. One end of the transmission shaft is connected to the polishing head, and the other end of the transmission shaft extends into the interior of the machine shell. A first connecting shaft and a buffer spring are mounted at the end of the transmission shaft extending into the interior of the machine shell. The first connecting shaft is connected to the intermittent structure, and the other end of the first connecting shaft is mounted with a second connecting shaft connected to the second driving component; The temperature reduction structure includes a liquid storage tank, an expansion pipe and a throat pipe mounted on the connecting frame. An infusion pipe connected to the throat pipe is fixed on the liquid storage tank. A spray pipe is fixed at one end of the throat pipe, and a fan connected to the first driving component is mounted at the end of the expansion pipe.
[0007] Preferably: The interior of the machine shell is hollowly arranged. The driving structure is arranged outside the machine shell, and one of the gears in the driving structure is mounted on the outer surface of the transmission sleeve. The machine shell is connected to the output end of the telescopic device through a connecting frame.
[0008] The beneficial effect of adopting the above further scheme is that the hollow design of the machine shell reduces the material consumption of the machine shell, reduces the overall weight, and at the same time provides sufficient space for components such as the transmission shaft and the buffer spring to avoid movement interference. At the same time, through the displacement control of the telescopic device, the contact pressure between the polishing head and the agate surface can be adjusted in real time, avoiding the agate from cracking due to excessive pressure or affecting the polishing efficiency due to insufficient pressure. The output of the telescopic device can drive the temperature reduction structure, simplifying the operation process and achieving the advantage of automatic triggering.
[0009] Preferably: The end of the buffer spring away from the transmission shaft is connected to the inner wall of the machine shell. The connection mode of the buffer spring and the transmission shaft is a rotational connection, and the buffer spring surrounds the outside of the first connecting shaft. The connection between the second connecting shaft and the first connecting shaft is a rotational connection.
[0010] The beneficial effect of adopting the above further scheme is that the buffer spring surrounds the outside of the first connecting shaft. When the polishing head generates an instantaneous resistance due to uneven hardness on the agate surface, the spring absorbs the impact energy through axial compression, avoiding the transmission shaft from bending or breaking due to overload. At the same time, the installation of the buffer spring can cooperate with the output of the telescopic device to enable the transmission component 12 to perform better transmission work.
[0011] Preferably, the intermittent structure includes a rotating base rotatably mounted on the connecting frame. A groove is formed inside the rotating base, and a rotating block is arranged in the groove. A connecting sleeve is fixed inside the rotating block. An elastic guide shaft is arranged inside the rotating block, and an abutting block abutted against the groove is installed at the end of the elastic guide shaft. A rotating sleeve is sleeved on the outer wall of the connecting sleeve. A connecting arm is hinged between the rotating sleeve and the abutting block. A spline block spline-connected to the connecting sleeve is fixed on the outer wall of the first connecting shaft.
[0012] The beneficial effect of adopting the above further scheme is that through the output of the telescopic device, the transmission component contracts. The first connecting shaft drives the connecting sleeve and the rotating block to rotate by means of the spline connection between the spline block and the connecting sleeve. When the rotating block rotates, a centrifugal force is generated through the abutting block, so that the abutting block abuts against the inner side of the rotating base, thereby driving the rotating base to rotate, and cooperating with the transmission of the first driving component to make the fan work, realizing cooling.
[0013] Preferably, the connecting sleeve is a hollow shaft. The second connecting shaft penetrates through the inside of the connecting sleeve and is connected to the second driving component. The connecting sleeve penetrates through the inside of the rotating block and the rotating base and is rotatably connected to the outer wall of the connecting frame.
[0014] The beneficial effect of adopting the above further scheme is that the connecting sleeve is designed as a hollow shaft, allowing the second connecting shaft to directly penetrate through its inside, avoiding the radial space occupation caused by the traditional solid shaft, shortening the axial layout of the transmission component and the intermittent structure, and adapting to the narrow installation space of precision machining equipment.
[0015] Preferably, a first return spring is rotatably installed between the rotating sleeve and the rotating block. The number of the elastic guide shafts, the abutting blocks and the connecting arms is two, and the two abutting blocks are symmetrically distributed.
[0016] The beneficial effect of adopting the above further scheme is that the first return spring is installed between the rotating sleeve and the rotating block and is rotatably installed. After the external force applied to the mechanism is removed, the first return spring can effectively generate torque or torsion force, driving the rotating sleeve to automatically and accurately return to the initial preset position or the balance position, ensuring the repeated positioning accuracy and the reliability of the operation of the mechanism, and at the same time enhancing the stability and balance of the mechanism. The number of the elastic guide shafts, the abutting blocks and the connecting arms is set to two, and the two abutting blocks are symmetrically distributed, so that the forces or torques acting on the key components of the mechanism are balanced on both sides, avoiding the phenomena of uneven load, increased wear or jamming caused by excessive unilateral force.
[0017] Preferably, the first driving component includes a driving shaft rotatably installed on the outer wall of the connecting frame. The other end of the driving shaft is fixed to the outer wall of the fan. Synchronous wheels are fixed between the driving shaft and the rotating base, and a synchronous belt is installed between the two synchronous wheels for transmission.
[0018] The beneficial effects of adopting the above further scheme are as follows: The drive shaft is linked with the turntable through the synchronous belt, while driving the fan to rotate to generate a cooling air flow, and driving the stirring rod to rotate through the transmission gear to prevent the coolant from precipitating. A single drive source realizes three core functions, such as the rotation of the polishing head, cooling, and homogenization of the coolant, reducing the number of motors and the equipment cost.
[0019] Preferably, the liquid storage tank is fixed to the top side of the connecting frame. A stirring rod is rotatably installed inside the liquid storage tank, and the stirring rod penetrates through the inside of the liquid storage tank and the connecting frame. The first drive assembly further includes a transmission gear fixed to the outer wall of the drive shaft, and an idle gear fixed to the bottom end of the stirring rod is externally engaged with the transmission gear.
[0020] The beneficial effects of adopting the above further scheme are as follows: The liquid storage tank is fixed to the top side of the connecting frame, making full use of the space above the equipment, making the overall structure more compact, ensuring the stability of the liquid storage tank, preventing it from shaking during operation, guaranteeing the stability and safety of liquid treatment. At the same time, a stirring rod is rotatably installed inside the liquid storage tank to directly stir the stored liquid. This design can effectively prevent the components in the liquid from stratifying or precipitating, ensure the liquid is evenly mixed, and maintain the stability and consistency of its physical and chemical properties.
[0021] Preferably, the second drive assembly includes a sliding seat. A chute is formed inside the sliding seat. The chute is inclined, and a roller is rotatably connected inside it. A shaft rod is rotatably installed inside the roller, and the other end of the shaft rod is provided with a drive frame. The end of the second connecting shaft far from the first connecting shaft is fixed to the outer wall of the sliding seat.
[0022] The beneficial effects of adopting the above further scheme are as follows: When the second connecting shaft drives the sliding seat to perform a linear motion, the inclined chute will force the internal roller to generate a lateral displacement component along the groove trajectory. Through the rigid connection of the shaft rod, the combined motion of the roller is converted into a linear motion of the drive frame in a specific direction. The linear motion of the second connecting shaft 124 in one direction is cleverly converted into an accurate linear motion of the drive frame in another direction through the inclined chute and the roller, realizing an efficient conversion of the motion direction and stroke.
[0023] Preferably, the second drive assembly further includes a valve rotatably arranged inside the infusion tube. One end of the valve is fixed with a drive rod extending outside the infusion tube. One end of the drive rod is fixed with a drive gear, and a tooth block meshing with the drive gear is fixed to the side of the drive frame close to the infusion tube.
[0024] The beneficial effect of adopting the above further scheme is: the gear block is driven by the linear motion of the drive frame, and the gear block engages to drive the gear to rotate, and then the rotation angle of the valve inside the infusion tube is controlled by the drive rod. This design can accurately convert the linear displacement of the drive frame into the rotation angle of the valve, thereby realizing accurate and reliable adjustment of the fluid on and off or the flow rate.
[0025] The present invention has at least the following beneficial effects: 1. In the present invention, when the polishing head is driven to fit the agate by the telescopic device, the transmission component automatically contracts, and the cooling structure can be linked and started without an additional sensor or control unit, thereby simplifying the operation process and achieving the advantage of automatic triggering. When the rotating block rotates, the abutment block abuts against the inner side of the rotating seat due to the centrifugal force, directly driving the rotating seat to rotate, and then driving the fan to work through the synchronous belt. This process completely relies on mechanical energy transmission, does not require an independent motor, reduces energy consumption, and achieves the advantages of energy saving and high efficiency. In addition, when the airflow generated by the fan passes through the throat, the Venturi effect is used to atomize the coolant into tiny droplets, which significantly increases the contact area between the coolant and the polishing area, accelerates heat exchange, and improves the cooling efficiency.
[0026] In the present invention, when the airflow driven by the fan passes through the expansion tube and the throat tube, the stirring rod is synchronously driven to rotate, so as to prevent the coolant in the liquid storage tank from settling, ensure the uniformity of the coolant, and improve the stability of the cooling effect. When the mist coolant is sprayed from the nozzle, it can be directed to the contact area between the polishing head and the agate, so as to prevent the coolant from diffusing to the non-processing area and reduce the risk of secondary pollution to the agate surface. 3. In the present invention, the second driving assembly converts the rotational motion of the second connecting shaft into the reciprocating motion of the driving frame through the rolling connection between the inclined sliding groove of the sliding seat and the roller, and then adjusts the valve opening through the engagement of the tooth block and the driving gear, thereby realizing the dynamic matching of the coolant flow rate and the polishing process and avoiding the waste of resources. Among them, the initial cooling and the further cooling are automatically switched through the displacement of the telescopic device without manual intervention, which adapts to the difference in heat generation in different polishing stages such as rough polishing and fine polishing, and improves the process flexibility.
[0027] In the present invention, when the second connecting shaft drives the slide to make linear motion, the inclined slide groove forces the internal roller to generate a lateral displacement component along the groove trajectory. Through the rigid connection of the shaft rod, the compound motion of the roller is converted into the linear motion of the drive frame in a specific direction. The linear motion of the second connecting shaft 124 in one direction is cleverly converted into precise linear motion of the drive frame in another direction through the inclined slide groove and the roller, thereby realizing efficient conversion of motion direction and stroke.

Detailed implementation manners
[0030] The technical solutions of the present invention will be further described in detail below in conjunction with the specific implementation manners.
[0031] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.
[0032] As Figures 1-9As shown in the figure, the surface uniform fine polishing device for agate production provided in this embodiment includes a polishing device 1 for polishing agate. The polishing device 1 is composed of a casing 11, a transmission assembly 12, a driving structure 13, and a polishing head 14. A connecting frame 2 is arranged on the casing 11. Specifically, the transmission assembly 12 includes a transmission sleeve 121 and a transmission shaft 122 connected by splines. One end of the transmission shaft 122 is connected to the polishing head 14, and the other end of the transmission shaft 122 extends into the interior of the casing 11. A first connecting shaft 123 and a buffer spring 125 are installed at the end of the transmission shaft 122 extending into the interior of the casing 11. Among them, the interior of the casing 11 is hollowly arranged. The driving structure 13 is arranged outside the casing 11, and one of the gears in the driving structure 13 is installed on the outer surface of the transmission sleeve 121. The casing 11 is connected to the output end of the telescopic device through the connecting frame 2.
[0033] It should be noted that the hollow design of the casing 11 reduces the material consumption of the casing 11 and the overall weight. At the same time, it provides sufficient space for components such as the transmission shaft 122 and the buffer spring 125 to avoid movement interference. At the same time, through the displacement control of the telescopic device, the contact pressure between the polishing head 14 and the agate surface can be adjusted in real time, avoiding the agate from cracking due to excessive pressure or affecting the polishing efficiency due to insufficient pressure.
[0034] In this embodiment, the connecting frame 2 is respectively provided with an intermittent structure 3 connected to the transmission assembly 12, a first driving component 5 that cooperates with the intermittent structure 3, and a second driving component 6, and a cooling structure 4 installed on the connecting frame 2. The first connecting shaft 123 is connected to the intermittent structure 3, and a second connecting shaft 124 connected to the second driving component 6 is installed at the other end of the first connecting shaft 123. The output of the telescopic device can drive the cooling structure 4, simplifying the operation process and achieving the advantage of automatic triggering.
[0035] One end of the buffer spring 125 away from the transmission shaft 122 is connected to the inner wall of the casing 11. The connection mode between the buffer spring 125 and the transmission shaft 122 is a rotational connection, and the buffer spring 125 is wound around the outside of the first connecting shaft 123. The connection between the second connecting shaft 124 and the first connecting shaft 123 is a rotational connection. The buffer spring 125 is wound around the outside of the first connecting shaft 123. When the polishing head 14 generates instantaneous resistance due to uneven hardness of the agate surface, the spring absorbs the impact energy through axial compression, avoiding the transmission shaft 122 from bending or breaking due to overload. At the same time, the installation of the buffer spring 125 can cooperate with the output of the telescopic device to enable the transmission assembly 12 to perform better transmission work.
[0036] To achieve the linkage between the polishing device 1 and the cooling structure 4, the intermittent structure 3 includes a turntable 31 rotatably mounted on the connecting frame 2. A groove is formed inside the turntable 31, and a rotating block 32 is arranged in the groove. A connecting sleeve 33 is fixed inside the rotating block 32. An elastic guide shaft 35 is arranged inside the rotating block 32, and an abutting block 36 abuting against the groove is mounted at the end of the elastic guide shaft 35. A rotating sleeve 34 is sleeved on the outer wall of the connecting sleeve 33. A connecting arm 37 is hinged between the rotating sleeve 34 and the abutting block 36. A spline block spline-connected to the connecting sleeve 33 is fixed on the outer wall of the first connecting shaft 123.
[0037] Output through the telescopic device, the transmission component 12 contracts. By using the fact that the first connecting shaft 123 is spline-connected to the connecting sleeve 33 through the spline block, the connecting sleeve 33 and the rotating block 32 are driven to rotate. When the rotating block 32 rotates, a centrifugal force is generated through the abutting block 36, so that the abutting block 36 abuts against the inner side of the turntable 31, thereby driving the turntable 31 to rotate. Cooperating with the transmission of the first driving component 5, the fan 47 works to achieve cooling. Specifically, the connecting sleeve 33 is a hollow shaft. The second connecting shaft 124 passes through the inside of the connecting sleeve 33 and is connected to the second driving component 6. The connecting sleeve 33 passes through the inside of the rotating block 32 and the turntable 31 and is rotatably connected to the outer wall of the connecting frame 2. Through the design that the connecting sleeve 33 is a hollow shaft, it allows the second connecting shaft 124 to directly pass through its inside, avoiding the radial space occupation caused by the traditional solid shaft, shortening the axial layout of the transmission component 12 and the intermittent structure 3, and adapting to the narrow installation space of the precision machining equipment. The elastic guide shaft 35 is composed of a guide rod and a spring.
[0038] Wherein, a first return spring is rotatably mounted between the rotating sleeve 34 and the rotating block 32. The number of the elastic guide shafts 35, the abutting blocks 36 and the connecting arms 37 is two, and the two abutting blocks 36 are symmetrically distributed. The first return spring is installed between the rotating sleeve 34 and the rotating block 32 and is rotatably mounted. After the external force applied to the mechanism is removed, the first return spring can effectively generate torque or torsion force to drive the rotating sleeve 34 to automatically and accurately return to the initial preset position or the equilibrium position, ensuring the repeated positioning accuracy and the reliability of the operation of the mechanism. At the same time, it enhances the stability and balance of the mechanism. The number of the elastic guide shafts 35, the abutting blocks 36 and the connecting arms 37 is set to two, and the two abutting blocks 36 are symmetrically distributed, so that the forces or torques acting on the key components of the mechanism are balanced on both sides, avoiding the phenomena of uneven load, increased wear or jamming caused by excessive unilateral force. In addition, the symmetric abutting points and supporting points provided by the two abutting blocks 36 and the two elastic guide shafts 35 can more effectively restrict the movement trajectory of the mechanism, prevent unnecessary shaking or deviation during the movement process, and ensure smooth movement.
[0039] To achieve the cooling of agate, the cooling structure 4 includes a liquid storage tank 41, an expansion pipe 43, and a throat pipe 44 installed on the connecting frame 2. A liquid infusion pipe 42 connected to the throat pipe 44 is fixed on the liquid storage tank 41. A spray pipe 45 is fixed at one end of the throat pipe 44. A fan 47 connected to the first driving assembly 5 is installed at the end of the expansion pipe 43. The first driving assembly 5 includes a driving shaft 51 rotatably installed on the outer wall of the connecting frame 2. The other end of the driving shaft 51 is fixed to the outer wall of the fan 47. Synchronous wheels 52 are fixed between the driving shaft 51 and the rotating seat 31, and a synchronous belt 53 is installed between the two synchronous wheels 52 for transmission. Specifically, the driving shaft 51 is linked to the rotating seat 31 through the synchronous belt 53, simultaneously driving the fan 47 to rotate to generate a cooling air flow, and driving the stirring rod 46 to rotate through the transmission gear 54 to prevent the coolant from precipitating. A single driving source realizes three core functions, such as the rotation of the polishing head 14, cooling, and homogenization of the coolant, reducing the number of motors and lowering the equipment cost. In addition, when the air flow generated by the fan 47 passes through the throat pipe 44, the coolant is atomized into tiny droplets by using the Venturi effect, significantly increasing the contact area between the coolant and the polishing area, accelerating heat exchange, and enhancing the cooling efficiency.
[0040] Among them, the liquid storage tank 41 is fixed on the top side of the connecting frame 2. A stirring rod 46 is rotatably installed inside the liquid storage tank 41, and the stirring rod 46 penetrates through the inside of the liquid storage tank 41 and the connecting frame 2. The first driving assembly 5 further includes a transmission gear 54 fixed on the outer wall of the driving shaft 51, and an idle gear 55 engaged with the outside of the transmission gear 54 and fixed to the bottom end of the stirring rod 46. The liquid storage tank 41 is fixed on the top side of the connecting frame 2, making full use of the space above the equipment, making the overall structure more compact, ensuring the stability of the liquid storage tank 41, preventing it from shaking during operation, ensuring the stability and safety of liquid processing. At the same time, a stirring rod 46 is rotatably installed inside the liquid storage tank 41 to directly stir the stored liquid. This design can effectively prevent the components in the liquid from stratifying or precipitating, ensuring the liquid is evenly mixed and maintaining the stability and consistency of its physical and chemical properties.
[0041] It should be noted that this design cleverly integrates the stirring function into the power output chain of the first driving assembly 5, which means that while the same driving source, the driving shaft 51, drives its original functional components, through the meshing of the transmission gear 54, the power is efficiently and directly transmitted to the stirring rod 46 to drive it to rotate and stir, without the need to configure an independent motor or driving device for the stirring function additionally.
[0042] To further enhance the cooling function, the second drive assembly 6 includes a sliding seat 61. A chute 65 is formed inside the sliding seat 61. The chute 65 is inclined, and a roller 64 is rotatably connected inside it. A shaft rod 63 is rotatably installed inside the roller 64. The other end of the shaft rod 63 is provided with a drive bracket 62. One end of the second connecting shaft 124 away from the first connecting shaft 123 is fixed to the outer wall of the sliding seat 61. When the second connecting shaft 124 drives the sliding seat 61 to perform a linear motion, the inclined chute 65 will force the internal roller 64 to generate a lateral displacement component along the groove track. Through the rigid connection of the shaft rod 63, the combined motion of the roller 64 is converted into a linear motion of the drive bracket 62 in a specific direction. Cleverly, the linear motion of the second connecting shaft 124 in one direction is converted into an accurate linear motion of the drive bracket 62 in another direction through the inclined chute 65 and the roller 64, realizing an efficient conversion of the motion direction and stroke. A limiting member for limiting is installed on the connecting bracket 2. The displacement of the drive bracket 62 will not affect the drive of the drive shaft 51.
[0043] Among them, the second drive assembly 6 further includes a valve 68 rotatably arranged inside the infusion tube 42. One end of the valve 68 is fixed with a drive rod 67 extending outside the infusion tube 42. One end of the drive rod 67 is fixed with a drive gear 69. A tooth block 66 meshing with the drive gear 69 is fixed to one side of the drive bracket 62 close to the infusion tube 42. By driving the tooth block 66 through the linear motion of the drive bracket 62, the tooth block 66 meshes with the drive gear 69 to rotate, and then the rotation angle of the valve 68 inside the infusion tube 42 is controlled through the drive rod 67. This design can accurately convert the linear displacement of the drive bracket 62 into the rotation angle of the valve 68, realizing precise and reliable adjustment of the fluid on-off or flow rate.
[0044] It is worth mentioning that through the meshing of the drive gear 69 and the tooth block 66, the linear motion of the drive bracket 62 is innovatively and efficiently converted into the rotational motion of the valve 68, realizing the synchronous linkage of the opening and closing of the valve 68 and the main drive action. This not only eliminates the need for an independent valve 68 drive device, simplifies the structure and reduces the cost, but also ensures the accuracy, response speed and reliability of fluid control. At the same time, the design of internal and external isolation effectively guarantees the sealing performance and maintainability.
[0045] In addition, the inclination angle of the inclined chute 65 is the core design parameter. This angle directly determines the proportional relationship between the moving distance of the input displacement sliding seat 61 and the moving distance of the output displacement drive bracket 62. Small-angle inclination: The displacement of the drive bracket 62 can be amplified relative to the displacement of the sliding seat 61, or it may be possible to achieve reduction or a more direct conversion. This design allows precise control of the displacement amount at the output end through a simple mechanical structure, meeting the requirements for the stroke under different working conditions.
[0046] Such as Figures 1-9As shown in the figure, the principle of the surface uniform fine polishing device for agate production provided in this embodiment is as follows: The driving structure 13 drives the transmission sleeve 121 to rotate through a gear. The transmission sleeve 121 is splined to the transmission shaft 122 to transmit power to the polishing head 14 to achieve the polishing action. When preliminary cooling is required, the telescopic device drives the polishing device 1 to move. Since the polishing head 14 is in contact with the agate, at this time, the transmission component 12 contracts, and the transmission shaft 122 extends into the machine shell 11. At this time, the first connecting shaft 123 is splined to the connecting sleeve 33 through the spline block. When the first connecting shaft 123 rotates, it drives the rotating block 32 to rotate through the connecting sleeve 33. When the rotating block 32 rotates, a centrifugal force is generated through the abutting block 36, so that the abutting block 36 abuts against the inner side of the rotating seat 31, thereby driving the rotating seat 31 to rotate. The rotation of the rotating seat 31 drives the fan 47 to work through the transmission of the first driving component 5. The fan 47 is directly driven by the driving shaft 51 to generate an air flow that is compressed by the expansion pipe 43 and the throat pipe 44 and finally ejected through the nozzle 45 to achieve the cooling of the agate and the polishing head 14. In addition, when the driving shaft 51 in the first driving component 5 works, it will also drive the stirring rod 46 to rotate to prevent the coolant from precipitating, which is convenient for the subsequent use of the second driving component 6. When further improving the cooling, the telescopic device further extends and retracts. At this time, the second connecting shaft 124 moves a sufficient distance, and the driving frame 62 is driven to move through the cooperation of the sliding seat 61, the inclined chute 65 and the roller 64. The movement of the driving frame 62 adjusts the angle of the valve 68 through the engagement of the tooth block 66 and the driving gear 69. When the fan 47 works, an air flow is generated through the expansion pipe 43 and the throat pipe 44, and the coolant in the liquid storage tank 41 is inhaled into the throat pipe 44 by using the Venturi effect through the infusion pipe 42, and a mist-like coolant is ejected from the nozzle 45 to accurately cool the polishing area and achieve efficient cooling.
