Description

Technical Field

[0001] The utility model belongs to the technical field of grinding wheel fixing and installation, and particularly relates to a fixing and installation structure of a grinding wheel. Background Technique

[0002] A special grinding wheel for pneumatic tools to grind cemented carbide is a grinding tool specially designed for pneumatic grinding tools. It adopts an optimized design aiming at the characteristics of cemented carbide materials, has high strength, high wear resistance and good heat dissipation performance, and is suitable for precision grinding of high-hardness materials such as cemented carbide, such as grinding the edges of metal cutting tools such as drills and milling cutters. Such grinding wheels usually have a fine abrasive grain distribution and an appropriate binder hardness, which can reduce the damage to the workpiece surface while ensuring the grinding efficiency, ensure the smoothness and accuracy of the processed surface, and are widely used in industries such as mechanical manufacturing and mold processing. Especially suitable for occasions that require handheld operation and high flexibility, such as on-site maintenance, mold repair and other application scenarios. The combination of pneumatic tools and special grinding wheels not only improves the efficiency of grinding operations, but also reduces the labor intensity of operators. It is one of the indispensable important tools in modern industrial production.

[0003] When the existing pneumatic tools install the grinding wheel, it may not be firmly fixed. The problems existing in the above technology are: when the existing pneumatic tools install the grinding wheel, if the fixing is not firm, a series of problems may occur. First of all, during the high-speed rotation of the grinding wheel, if the fixing structure is not stable enough, it is easy to loosen or even fall off. This will not only seriously affect the normal progress of the grinding operation, but also may cause the grinding wheel to fly out, resulting in serious safety accidents. Secondly, poor fixing will cause unnecessary vibration of the grinding wheel during use, which will not only affect the surface quality and accuracy of the processed parts, but also may accelerate the wear of the grinding wheel itself and shorten its service life. In addition, unstable fixing will also lead to a reduction in the working efficiency of the pneumatic tool and an increase in the fatigue degree of the operator, especially in the case of long-term continuous operation, these problems are particularly prominent. Content of the Utility Model

[0004] Aiming at the problems existing in the prior art, the utility model provides a fixing and installation structure of a grinding wheel that can overcome or at least partially solve the above problems.

[0005] The utility model is realized as follows: A fixing and installation structure of a grinding wheel includes a grinding machine, a grinding wheel and a connection end. The lower side of the front end of the grinding machine is in contact with the grinding wheel, the rear end of the grinding machine is fixedly connected to the connection end, a fixing device is arranged on the lower side of the front end of the grinding machine, and an auxiliary component is arranged on the surface of the fixing device;

[0006] The fixing device is used to fix the grinding wheel;

[0007] The auxiliary component is used to enhance the fixing effect.

[0008] To improve the installation efficiency, preferably, the fixing device includes a top rod, a fixing block, an activity groove, a limiting rod, an elastic block, a supporting block, and a limiting groove. Four of the activity grooves are opened on the surface of the fixing block. The inner wall of the activity groove is slidably connected to the surfaces of the four limiting rods. The front ends of the four limiting rods are fixedly connected to the surfaces of the two supporting blocks. The rear surfaces of the four limiting rods are slidably connected to the front surface of the top rod. The lower ends of the four limiting rods are fixedly connected to the four elastic blocks. The limiting groove is opened on the inner wall of the grinding wheel. The activity groove is opened on the surface of the fixing block and is slidably connected to the surfaces of the four limiting rods. This design allows the limiting rod to slide along the direction of the activity groove when subjected to an external force, thereby realizing the extension or retraction of the limiting rod. The front ends of the four limiting rods are fixedly connected to the two supporting blocks. Such a design enables the supporting block to move along with the movement of the limiting rod, and then insert into or withdraw from the limiting groove on the grinding wheel. The presence of the supporting block enhances the stability of the grinding wheel after installation and prevents it from displacing or vibrating during high-speed rotation. The surface of the top rod and the inner wall of the fixing block are meshed with each other through threads. This mechanical connection method not only ensures the accuracy and smoothness of the top rod during operation but also increases the reliability of the entire device. By rotating the top rod, the extension and retraction of the limiting rod can be conveniently controlled, realizing the rapid installation and disassembly of the grinding wheel.

[0009] To improve the safety during use, preferably, the auxiliary component includes an auxiliary block, a mating rod, a clamping block, a spring, and a positioning rod. One end of the two mating rods is fixedly connected to the inner wall of the auxiliary block. The inner wall of the front ends of the two mating rods is slidably connected to the surface of the clamping block. One end of the spring is fixedly connected to the surface of the clamping block. One end of the two positioning rods is fixedly connected to the two side surfaces of the fixing block. The inner wall of the front end of the mating rod is slidably connected to the surface of the clamping block, and one end of the spring is fixedly connected to the surface of the clamping block. This design enables the clamping block to automatically pop out and latch onto the positioning rod under the action of the spring, thereby realizing the quick locking function. The elastic restoring force provided by the spring can ensure that the clamping block is always in the locked state when not subjected to external forces, effectively preventing the grinding wheel from displacing due to insufficient fixation during use. One end of the two positioning rods is fixedly connected to the two side surfaces of the fixing block, and the positioning rod provides an accurate guiding path for the mating rod.

[0010] To improve the stability of the device, preferably, the surface of the fixed block is fixedly connected to the output end of the grinding machine, the inner wall of the fixed block is threadedly connected to the surface of the ejector rod, the surfaces of the two support blocks are slidably connected to the inner wall of the limiting groove, the surfaces of the four elastic blocks are fixedly connected to the inner wall of the fixed block, and the surface of the fixed block is fixedly connected to the output end of the grinding machine. This design ensures that the fixed block can directly obtain power from the output end of the grinding machine, enabling the grinding wheel to rotate stably and efficiently in a fixed state. In addition, the fixed connection also guarantees that during long-term use, the connection between the grinding wheel and the grinding machine will not become loose due to vibration or other factors, thereby improving the safety and reliability of the overall equipment. The inner wall of the fixed block is threadedly connected to the surface of the ejector rod, and the ejector rod can achieve axial feeding motion. In addition, the self-locking characteristic of the thread can also prevent the ejector rod from loosening accidentally during the high-speed rotation of the grinding wheel, further ensuring the safety of the operator. The support blocks are provided to provide additional support points during the installation of the grinding wheel. By matching with the pre-set limiting grooves on the inner wall of the grinding wheel, the support blocks can enter the limiting grooves under the action of the ejector rod, thereby achieving the preliminary positioning of the grinding wheel. The surfaces of the four elastic blocks are fixedly connected to the inner wall of the fixed block, and the main function of the elastic blocks is to provide a restoring force during the process of the limiting rod withdrawing from the limiting groove, enabling it to automatically reset.

[0011] To improve the reliability of the fixation, preferably, the surface of the auxiliary block contacts the upper surface of the ejector rod, the inner wall of the positioning rod is slidably connected to the surface of the mating rod, the surface of the locking block contacts the inner wall of the positioning rod, and the surface of the spring is fixedly connected to the inner wall of the positioning rod. The contact surface of the auxiliary block can evenly distribute the pressure, preventing the ejector rod from shifting or loosening due to uneven force during the high-speed rotation of the grinding wheel, ensuring the stability of the grinding wheel during use and reducing potential safety hazards. The inner wall of the positioning rod is slidably connected to the surface of the mating rod, enabling the mating rod to move smoothly inside the positioning rod, and then driving the locking block to achieve the functions of locking and unlocking. As part of the locking mechanism, the locking block can effectively fix the mating rod in the positioning rod through contact with the inner wall of the positioning rod during the installation process. This contact method ensures that the fixed structure of the grinding wheel will not fail due to external impact or vibration during the working state, thereby enhancing the overall safety of the system.

[0012] To improve the durability of the device, preferably, the surfaces of the two positioning rods are slidably connected to the inner wall of the grinding wheel, and the inner wall of the grinding wheel is slidably connected to the surface of the fixed block. The surface of the positioning rod is slidably connected to the inner wall of the grinding wheel. This design allows the grinding wheel to move smoothly along the positioning rod during the installation process until it reaches the predetermined position. The positioning rod not only provides a guiding function for the grinding wheel but also plays a supporting role, ensuring that the grinding wheel will not be skewed during the installation process. The inner wall of the grinding wheel is slidably connected to the surface of the fixed block. This connection method enables the grinding wheel to move smoothly along the surface of the fixed block during installation until it finally fits in place.

[0013] To improve the installation efficiency, preferably, limiting rings are provided on the lower end surfaces of the two positioning rods. The inner wall of the limiting ring is fixedly connected to the surface of the fixing block. One side surface of the grinding wheel contacts the surface of the limiting ring. This design ensures that the grinding wheel can have a clear position reference after installation. The limiting ring acts as a stop member, which can prevent the grinding wheel from moving further in the axial direction, thus ensuring the accurate installation position of the grinding wheel.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] The present utility model is provided with a fixing device, an auxiliary component, a ejector rod, a fixing block, a limiting rod, an elastic block, a supporting block, an auxiliary block, a mating rod, a clamping block, a spring and a positioning rod. The fixing device is used to fix the grinding wheel, and the auxiliary component is used to enhance the fixing effect. An activity groove is opened on the surface of the fixing block and is slidably connected to the surfaces of the four limiting rods. This design allows the limiting rods to slide along the direction of the activity groove when subjected to external forces, thereby realizing the extension or retraction of the limiting rods. The front ends of the four limiting rods are fixedly connected to two supporting blocks. Such a design enables the supporting blocks to move along with the movement of the limiting rods, and then insert into or withdraw from the limiting grooves on the grinding wheel. The presence of the supporting blocks enhances the stability of the grinding wheel after installation and prevents it from displacing or vibrating during high-speed rotation. The surface of the ejector rod is meshed with the inner wall of the fixing block through threads. This mechanical connection method not only ensures the accuracy and stability of the ejector rod during operation but also increases the reliability of the entire device. By rotating the ejector rod, the expansion and contraction of the limiting rods can be conveniently controlled, realizing the rapid installation and disassembly of the grinding wheel. The inner wall of the front end of the mating rod is slidably connected to the surface of the clamping block, and the surface of the clamping block is fixedly connected to one end of the spring. This design enables the clamping block to automatically pop out and lock the positioning rod under the action of the spring, thereby realizing the quick locking function. The elastic restoring force provided by the spring can ensure that the clamping block is always in the locked state when not subjected to external forces, effectively preventing the grinding wheel from displacing due to insecure fixation during use. The two side surfaces of the fixing block are fixedly connected to one end of the two positioning rods. The positioning rods provide an accurate guiding path for the mating rod, solving the problems that may occur when the existing pneumatic tools install the grinding wheel. If the fixation is not firm, a series of problems may occur. First, during the high-speed rotation of the grinding wheel, if the fixing structure is not stable enough, it is easy to loosen or even fall off, which will not only seriously affect the normal progress of the grinding operation but also may cause the grinding wheel to fly out, resulting in serious safety accidents. Second, poor fixation will cause unnecessary vibration of the grinding wheel during use, which will not only affect the surface quality and accuracy of the workpiece being processed but also may accelerate the wear of the grinding wheel itself and shorten its service life. In addition, unstable fixation will also lead to a reduction in the working efficiency of the pneumatic tool and an increase in the fatigue degree of the operator, especially in the case of long-term continuous operation, these problems are particularly prominent.

The limiting groove 107 is opened on the inner wall of the grinding wheel 5, and the activity groove 103 is opened on the surface of the fixing block 102 and is slidably connected to the surfaces of the four limiting rods 104. This design allows the limiting rod 104 to slide along the direction of the activity groove 103 when subjected to an external force, so as to realize the extension or retraction of the limiting rod 104. The front ends of the four limiting rods 104 are fixedly connected to two support blocks 106. Such a design enables the support block 106 to move along with the movement of the limiting rod 104, and then insert into or withdraw from the limiting groove 107 on the grinding wheel 5. The presence of the support block 106 enhances the stability of the grinding wheel 5 after installation and prevents it from displacing or vibrating during high-speed rotation. The surface of the top rod 101 is meshed with the inner wall of the fixing block 102 through threads. This mechanical connection method not only ensures the accuracy and stability of the top rod 101 during operation, but also increases the reliability of the entire device. By rotating the top rod 101, the telescoping of the limiting rod 104 can be conveniently controlled, realizing the quick installation and disassembly of the grinding wheel 5. The auxiliary component 2 includes an auxiliary block 201, a matching rod 202, a clamping block 203, a spring 204, and a positioning rod 205.

The inner wall of the front ends of the matching rods 202 is slidably connected to the surface of the clamping block 203, and the surface of the clamping block 203 is fixedly connected to one end of the spring 204. This design enables the clamping block 203 to automatically pop out and lock the positioning rod 205 under the action of the spring 204, thus realizing the quick locking function. The elastic restoring force provided by the spring 204 can ensure that the clamping block 203 is always in the locked state when not subjected to an external force, effectively preventing the grinding wheel 5 from displacing due to loose fixation during use. One end of two positioning rods 205 is fixedly connected to the two side surfaces of the fixing block 102, and the positioning rod 205 provides an accurate guiding path for the matching rod 202.The surface of the fixed block 102 is fixedly connected to the output end of the grinding machine 4.

The surfaces of the two support blocks 106 are slidably connected to the inner wall of the limit groove 107. The surfaces of the four elastic blocks 105 are fixedly connected to the inner wall of the fixed block 102. The surface of the fixed block 102 is fixedly connected to the output end of the grinding machine 4. This design ensures that the fixed block 102 can directly obtain power from the output end of the grinding machine 4, so that the grinding wheel 5 can operate stably and efficiently in a fixed state. In addition, the fixed connection also ensures that during long-term use, the connection between the grinding wheel 5 and the grinding machine 4 will not become loose due to vibration or other factors, thus improving the safety and reliability of the overall equipment. The inner wall of the fixed block 102 is threadedly connected to the surface of the ejector rod 101. The ejector rod 101 can achieve axial feeding movement. In addition, the self-locking characteristic of the thread can also prevent the ejector rod 101 from accidentally loosening during the high-speed rotation of the grinding wheel 5, further ensuring the safety of the operator. The support block 106 is provided to provide an additional support point during the installation of the grinding wheel 5. By matching with the pre-set limit groove 107 on the inner wall of the grinding wheel 5, the support block 106 can enter the limit groove 107 under the action of the ejector rod 101, thus realizing the preliminary positioning of the grinding wheel 5. The surfaces of the four elastic blocks 105 are fixedly connected to the inner wall of the fixed block 102. The main function of the elastic block 105 is to provide a restoring force during the process of the limit rod 104 withdrawing from the limit groove 107, so that it can automatically reset. The surface of the auxiliary block 201 contacts the upper surface of the ejector rod 101. The inner wall of the positioning rod 205 is slidably connected to the surface of the mating rod 202. The surface of the locking block 203 contacts the inner wall of the positioning rod 205. The surface of the spring 204 is fixedly connected to the inner wall of the positioning rod 205.

As a part of the locking mechanism, the locking block 203 can effectively fix the mating rod 202 in the positioning rod 205 through contact with the inner wall of the positioning rod 205 during the installation process. This contact method ensures that the fixed structure of the grinding wheel 5 will not fail due to external impact or vibration during the working state, thus enhancing the overall safety of the system. The surfaces of the two positioning rods 205 are slidably connected to the inner wall of the grinding wheel 5. The inner wall of the grinding wheel 5 is slidably connected to the surface of the fixed block 102. The surface of the positioning rod 205 is slidably connected to the inner wall of the grinding wheel 5. This design allows the grinding wheel 5 to move smoothly along the positioning rod 205 during the installation process until it reaches the predetermined position.

The inner wall of the grinding wheel 5 is slidably connected to the surface of the fixed block 102.This connection method enables the grinding wheel 5 to move smoothly along the surface of the fixed block 102 during installation until it finally fits in place. A limiting ring 3 is provided on the lower surface of the two positioning rods 205. The inner wall of the limiting ring 3 is fixedly connected to the surface of the fixed block 102. One side surface of the grinding wheel 5 contacts the surface of the limiting ring 3. One side surface of the grinding wheel 5 contacts the surface of the limiting ring 3. This design ensures that the grinding wheel 5 can have a clear position reference after installation. The function of the limiting ring 3 is equivalent to a stop piece, which can prevent the grinding wheel 5 from moving further in the axial direction, thus ensuring the accurate installation position of the grinding wheel 5.

[0024] The working principle of the present utility model:

[0025] Before using the grinding machine 4, a series of preparatory work must be carried out first. The primary step is to install the grinding wheel 5. The specific operations are as follows: First, align the holes pre-opened on the grinding wheel 5 with the fixed block 102 and the positioning rods 205. Then, press the grinding wheel 5 to ensure that it fits against the bottom of the fixed block 102 and is in close contact with the surface of the limiting ring. When the grinding wheel 5 is pushed to the correct position, the next step is to rotate the ejector rod 101. The surface of the ejector rod 101 is meshed with the inner wall of the fixed block 102 through threads. This design enables the ejector rod 101 to move smoothly within the inner wall of the fixed block 102. The thread engagement not only ensures the smooth movement of the ejector rod 101 but also effectively prevents the grinding wheel 5 from loosening during use. As the ejector rod 101 advances continuously, the slope at the front end of the ejector rod 101 will gradually contact the surfaces of the four limiting rods 104, pushing these four limiting rods 104 to move outward along the movable groove 103. The purpose of this action is to insert the support block 106 at the front end of the limiting rod 104, which is used for fixation, into the limiting groove 107 pre-opened on the grinding wheel 5, thereby realizing the preliminary fixed installation of the grinding wheel 5. Next, the mating rod 202 on the auxiliary block 201 needs to be pushed into the positioning rod 205. Through the latch 203 at the front end of the mating rod 202, the positioning rod 205 and the mating rod 202 can be firmly fixed together. In this way, the surface of the auxiliary block 201 can be in close contact with the surface of the ejector rod 101, further preventing the possible loosening of the ejector rod 101 during the high-speed rotation of the grinding machine 4, thus avoiding the risk of the grinding wheel 5 falling off. When the sand disc needs to be replaced, just push the latch 203 into the mating block, then the auxiliary block 201 can be pulled out first. Then, rotate the ejector rod 101 in the reverse direction to disengage the front end of the ejector rod 101 from the surface of the limiting rod 104. Due to the action of the elastic block 105, the limiting rod 104 will automatically retract into the fixed block 102. At this time, the grinding wheel 5 can be easily taken out and replaced.
