Description

Technical Field

[0001] This invention relates to the field of saw blade testing technology, specifically to a device for simulating and testing the impact resistance of diamond saw blades. Background Technology

[0002] Diamond saw blades, with their core advantages of high Mohs hardness and wear resistance, are widely used in stone processing, construction, road engineering, precision manufacturing and other fields. They can efficiently cut various materials such as marble, granite, concrete and high-hardness steel, and are an indispensable key tool in modern industrial production and infrastructure construction. Therefore, the process of testing the impact resistance of diamond saw blades is essential.

[0003] Existing testing equipment mostly uses traditional drop hammer impact testing machines or pendulum impact testing machines. These machines apply impact loads to the saw blade by allowing the hammer to fall freely or by swinging the pendulum. The impact resistance is then judged by observing the damage to the saw blade. The magnitude, direction, and speed of the impact load are mostly fixed, making it difficult to simulate the complex impact conditions faced by diamond saw blades during actual cutting. This makes it difficult to truly reflect the impact resistance performance of the saw blade in actual work. Moreover, the testing of the cutter head and the base body must be carried out separately and independently. Testing a single component cannot fully reflect the overall impact resistance level of the saw blade, which can easily lead to deviations in the test results. Summary of the Invention

[0004] The purpose of this invention is to provide a simulation and testing device for the impact resistance of diamond saw blades, in order to solve the problems mentioned in the background art, that existing testing devices are difficult to simulate the complex impact conditions faced by diamond saw blades in actual cutting processes, and are difficult to truly reflect the impact resistance performance of saw blades in actual work. Moreover, the testing of the cutter head and the substrate needs to be carried out separately and independently, and the testing of a single component cannot fully reflect the overall impact resistance level of the saw blade.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A diamond saw blade impact resistance simulation testing device includes a testing box, a testing platform fixed on the testing box, a protective cover fixedly installed on the testing platform, a control panel and a top plate respectively installed on the front and top of the protective cover, two electro-hydraulic rods fixed in the top plate, a support box fixedly installed at the bottom of the two electro-hydraulic rods, a blade impact-resistant component installed inside the support box, and support rods fixed at the four corners of the bottom of the support box, with a base impact-resistant component fixed at the bottom of the four support rods, the base impact-resistant component located below the blade impact-resistant component, testing components installed on the front and rear sides of the base impact-resistant component, a limiting component provided below the testing component, a diamond saw blade to be tested installed in the limiting component, a mounting frame installed inside the testing box, the limiting component sliding through the top of the mounting frame, the bottom end of the limiting component penetrating the mounting frame and fixed with a drive component, the drive component fixed to the bottom of the inner wall of the mounting frame, a transmission component meshing with the outside of the drive component, and the transmission component fixed to one side of the inner wall of the mounting frame.

[0007] As a further embodiment of the present invention, two inspection doors are installed on the front side of the mounting frame, and an annular collection box is fixedly installed on the inspection platform, the collection box being located below the diamond saw blade.

[0008] As a further embodiment of the present invention, the blade impact-resistant assembly includes two blade impact brackets. The ends of the two blade impact brackets that are far apart from each other are designed with an arc shape facing downwards. Gear seats are fixed at the ends of the two blade impact brackets that are close to each other. The middle part of the gear seats is rotatably connected to the support box through a shaft. The two gear seats mesh with each other. A transmission gear is fixed to the shaft of one of the gear seats. The transmission gear meshes with a drive gear. A rotary motor is fixed to the middle of the drive gear. The rotary motor is installed in the support box.

[0009] As a further embodiment of the present invention, the matrix impact-resistant component includes a matrix impact ring, four columns are fixed to the top of the matrix impact ring, the tops of the four columns are fixed to the bottom of the support box, and slide tracks are respectively opened on the front and rear sides of the matrix impact ring, and the detection component slides through the slide tracks.

[0010] As a further embodiment of the present invention, the detection component includes a sliding seat that slides through a slide rail. A dial indicator is installed at the end of the sliding seat away from the base impact ring. The bottom of the dial indicator is provided with a detection contact that passes through the base impact ring and extends downward. A limit screw is threadedly connected to the top of the base impact ring corresponding to the position of the sliding seat. The bottom end of the limit screw is tightly fitted with the top of the sliding seat.

[0011] As a further embodiment of the present invention, the limiting component includes a sliding column, a stud fixed to the top of the sliding column, a clamping nut externally threaded onto the stud, a retaining ring fixed to the outside of the sliding column, three limiting posts fixed on the retaining ring, the center hole of the diamond saw blade being sleeved on the outside of the sliding column and overlapping the retaining ring, and the three limiting posts being inserted through the diamond saw blade, the clamping nut being tightly fitted to the top of the diamond saw blade, and the bottom end of the sliding column penetrating the mounting frame and being fixedly connected to the top of the drive component.

[0012] As a further embodiment of the present invention, the drive assembly includes a support column, the top end of which is fixedly connected to the bottom end of a sliding column. A stop is fixed to the bottom of the support column. The stop is cylindrical in shape and has an annular groove on its outside. A sliding hole is formed at the bottom end of the support column. A sliding rod is slidably connected inside the sliding hole. Stop bars are fixed to both sides of the sliding rod. The sliding rod slides inside the sliding hole, and the two stop bars are slidably connected to guide grooves formed on both sides inside the sliding hole. A worm gear is fixed to the bottom end of the sliding rod, and the bottom end of the worm gear is fixed to the output shaft of the drive motor.

[0013] As a further embodiment of the present invention, the transmission assembly includes a fixed base, which is fixed to one side of the inner wall of the mounting frame. A support shaft rotates through the fixed base, and a worm gear is fixed outside the support shaft. The worm gear meshes with a worm. An eccentric seat is fixed to one end of the support shaft that passes through the fixed base. A sliding sleeve is rotatably fitted around the eccentric seat. A connecting rod is fixed to the top of the sliding sleeve. A rotating sleeve is fixed to the top of the connecting rod. A pin is rotatably fitted inside the rotating sleeve. Two extension rods rotatably pass through both sides of the pin. Rollers are installed at one end of the two extension rods and slide in an annular groove outside the stop seat. A rotating seat is rotatably fitted to the other end of the two extension rods via a pin. The rotating seat is installed on one side inside the mounting frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a motor to drive a worm gear, which in turn drives a stop bar via a sliding rod. The sliding rod slides within a hole at the bottom of the support column, while the stop bar slides synchronously within guide grooves on both sides of the sliding hole. This drives the stop seat to rotate, which in turn drives the diamond saw blade to rotate via the support column, stop ring, and limiting column. This simulates the working state of the diamond saw blade. Because the worm gear meshes with the worm wheel outside the support shaft, it drives the support shaft to rotate within the fixed seat. The eccentric seat rotates synchronously with the support shaft, causing the sliding sleeve to also perform a circular motion. The connecting rod fixed at the top of the sliding sleeve drives the rotating sleeve at its top to rotate around the pin. Two extension rods passing through the rotating sleeve on both sides then reciprocate around the pin in the rotating seat. Rollers installed at the other end of the extension rods are located outside the stop seat. The slide bar slides within the annular groove. While the extension rod swings, it pushes the stop and support column up and down through the rollers within the annular groove. This, in turn, drives the sliding column and the diamond saw blade at the top to rotate and complete the up and down reciprocating motion. Because the ends of the two impact frames that are far apart from each other are designed with an arc shape facing downwards, the cutting head of the diamond saw blade directly applies a periodic impact load to the impact frame. At the same time, the base in the middle of the diamond saw blade also impacts the base impact ring, applying a periodic impact load to the base impact ring. The speed of the drive motor can be adjusted through the control panel, thereby changing the frequency of the up and down reciprocating motion of the diamond saw blade. This simulates the impact intensity of the cutting head and base of the diamond saw blade under different working conditions. Simultaneously, the cutting head and base are tested to comprehensively reflect the overall impact resistance level of the saw blade and improve the testing accuracy. 2. In this invention, when performing impact resistance testing on the cutting heads of diamond saw blades of different specifications, a rotary motor is started, driving the drive gear on its output shaft to rotate synchronously. The drive gear meshes with the transmission gear on the outer side of one of the gear seats, thereby driving the gear seat to rotate around its central shaft within the support box. Due to the meshing of the two gear seats, the rotation of one gear seat drives the other gear seat to rotate synchronously in the opposite direction. The two gear seats respectively drive the fixedly connected cutting head impact frame to rotate in an arc around the gear seat as the axis. The arc structure at one end of the cutting head impact frame is aligned with the cutting head position of the diamond saw blade. When adjusting the position of the testing components, the limiting screw corresponding to the sliding seat position at the top of the base impact ring is loosened, pushing the sliding seat to slide within the slides opened on the front and rear sides of the base impact ring. This allows the sliding seat to drive the dial indicator and the testing contacts to correspond to the testing position on the surface of the diamond saw blade, thereby satisfying the testing work for diamond saw blades of different specifications.

Detailed Implementation

[0018] 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.

[0019] Please see Figures 1-9 The present invention provides a technical solution:

[0020] A diamond saw blade impact resistance simulation testing device includes a testing box 1, a testing platform 2 fixed on the testing box 1, a protective cover 3 fixedly installed on the testing platform 2, a control panel 4 and a top plate 5 respectively installed on the front and top of the protective cover 3, two electric hydraulic rods 6 fixed in the top plate 5, a support box 7 fixedly installed at the bottom end of the two electric hydraulic rods 6, and a blade impact resistance component 8 installed inside the support box 7.

[0021] The cutter head impact-resistant assembly 8 includes two cutter head impact brackets 802. The ends of the two cutter head impact brackets 802 that are far apart from each other are designed with an arc shape facing downwards. Gear seats 801 are fixed to the ends of the two cutter head impact brackets 802 that are close to each other. The middle part of the gear seats 801 is rotatably connected to the support box 7 through a shaft. The two gear seats 801 mesh with each other. A transmission gear 803 is fixed to the outside of the shaft in one of the gear seats 801. A drive gear 804 meshes with the transmission gear 803. A rotary motor 805 is fixed to the middle of the drive gear 804. The rotary motor 805 is installed in the support box 7.

[0022] During operation, the rotary motor 805 is started, driving the drive gear 804 on its output shaft to rotate synchronously. The drive gear 804 meshes with the transmission gear 803 on the outer side of one of the gear seats 801, thereby driving the gear seat 801 to rotate around the central shaft within the support box 7. Since the two gear seats 801 mesh with each other, the rotation of one gear seat 801 drives the other gear seat 801 to rotate synchronously in the opposite direction. The two gear seats 801 respectively drive the fixedly connected cutter head impact frame 802 to rotate in an arc around the gear seat 801 as the axis, aligning the arc structure at one end of the cutter head impact frame 802 with the cutter head position of the diamond saw blade, thus realizing the detection work of diamond saw blades of different specifications. Since the ends of the two cutter head impact frames 802 that are far apart from each other are designed with an arc facing downwards, the cutter head of the diamond saw blade will directly apply a periodic impact load to the cutter head impact frame 802, realizing the simulated detection action of the cutter head.

[0023] Support rods 9 are fixed at the four corners of the bottom of the support box 7. The bottom ends of the four support rods 9 are fixed with the base impact-resistant components 10, which are located below the cutter head impact-resistant components 8.

[0024] The matrix impact-resistant component 10 includes a matrix impact ring 101. Four columns 102 are fixed to the top of the matrix impact ring 101. The tops of the four columns 102 are fixed to the bottom of the support box 7. The matrix in the middle of the diamond saw blade simultaneously impacts the matrix impact ring 101, applying a periodic impact load to the matrix impact ring 101, thereby simulating the detection action of the matrix in the diamond saw blade.

[0025] The front and rear sides of the base impact-resistant component 10 are respectively equipped with detection components 11, and the front and rear sides of the base impact ring 101 are respectively provided with slides 103, and the detection components 11 slide through the slides 103.

[0026] The detection assembly 11 includes a sliding seat 111, which slides through the slide rail 103. A dial indicator 112 is installed at the end of the sliding seat 111 away from the base impact ring 101. A detection contact 113 is provided at the bottom of the dial indicator 112, and the detection contact 113 passes through the base impact ring 101 and extends downward. A limit screw 114 is threadedly connected to the top of the base impact ring 101 corresponding to the position of the sliding seat 111. The bottom end of the limit screw 114 is tightly fitted with the top of the sliding seat 111.

[0027] During operation, when adjusting the position of the detection component 11, loosen the limiting screw 114 at the top of the base impact ring 101 corresponding to the position of the sliding seat 111, and push the sliding seat 111 to slide in the slide rails 103 opened on the front and rear sides of the base impact ring 101, so that the sliding seat 111 drives the dial indicator 112 and the detection contact 113 to correspond to the detection position on the surface of the diamond saw blade, thus satisfying the detection work of diamond saw blades of different specifications.

[0028] A limiting component 13 is provided below the detection component 11. The diamond saw blade to be tested is installed in the limiting component 13. An installation frame 12 is installed inside the detection box 1. The limiting component 13 slides through the top of the installation frame 12. The bottom end of the limiting component 13 passes through the installation frame 12 and is fixed with a drive component 14. The drive component 14 is fixed to the bottom of the inner wall of the installation frame 12. A transmission component 16 is engaged on the outside of the drive component 14. The transmission component 16 is fixed to one side of the inner wall of the installation frame 12.

[0029] The limiting component 13 includes a sliding column 131, a stud 132 fixed to the top of the sliding column 131, a clamping nut 133 connected to the external thread of the stud 132, a retaining ring 134 fixed to the outside of the sliding column 131, three limiting posts 135 fixed on the retaining ring 134, the center hole of the diamond saw blade is sleeved on the outside of the sliding column 131 and overlaps the retaining ring 134, and the three limiting posts 135 are inserted through the diamond saw blade, the clamping nut 133 is tightly fitted with the top of the diamond saw blade, and the bottom end of the sliding column 131 passes through the mounting frame 12 and is fixedly connected to the top of the drive component 14.

[0030] During operation, three limiting posts 135 are inserted through the corresponding holes in the saw blade to achieve circumferential limiting of the saw blade and prevent the saw blade from rotating during the inspection process. Then, the clamping nut 133 on the outside of the stud 132 is tightened so that the clamping nut 133 fits tightly with the top of the saw blade, completing the axial clamping and fixing of the saw blade. Through the dual fixing method of mechanical limiting and thread clamping, it is ensured that the saw blade does not loosen or shift during subsequent impact and compound motion, providing a basic guarantee for the accuracy of the inspection.

[0031] The drive assembly 14 includes a support column 141, the top end of which is fixedly connected to the bottom end of a sliding column 131. A stop 142 is fixedly attached to the bottom of the support column 141. The stop 142 is cylindrical and has an annular groove 143 on its outside. A sliding hole 144 is provided at the bottom end of the support column 141. A sliding rod 145 is slidably connected inside the sliding hole 144. Stop bars 146 are fixed on both sides of the sliding rod 145. The sliding rod 145 slides inside the sliding hole 144. The two stop bars 146 are slidably connected in the guide grooves provided on both sides inside the sliding hole 144. A worm gear 147 is fixedly attached to the bottom end of the sliding rod 145. The bottom end of the worm gear 147 is fixed to the output shaft of the drive motor 15.

[0032] During operation, the worm gear 147 drives the stop bar 146 to rotate via the slide bar 145, causing the slide bar 145 to slide within the sliding hole 144 at the bottom of the support column 141. The stop bar 146 slides synchronously within the guide grooves on both sides of the sliding hole 144, thereby driving the stop seat 142 to rotate. During this process, the synchronous sliding of the stop bar 146 within the guide grooves on both sides of the sliding hole 144 ensures the stability of the diamond saw blade moving up and down driven by the support column 141 without displacement of the worm gear 147.

[0033] The transmission assembly 16 includes a fixed base 161, which is fixed to one side of the inner wall of the mounting frame 12. A support shaft 162 rotatably passes through the fixed base 161, and a worm gear 163 is fixed outside the support shaft 162, meshing with a worm 147. An eccentric seat 164 is fixed to one end of the support shaft 162 that passes through the fixed base 161. A sliding sleeve 165 rotatably fits around the eccentric seat 164, and a connecting rod 166 is fixed to the top of the sliding sleeve 165. A rotating sleeve 167 is fixed at the top of 166. A pin 168 is rotated inside the rotating sleeve 167. Two extension rods 169 rotate through the outer sides of the pin 168. Rollers 1691 are installed at one end of the two extension rods 169. The two rollers 1691 slide in the annular groove 143 outside the stop 142. The other end of the two extension rods 169 is rotated to a rotating seat 1692 through a pin. The rotating seat 1692 is installed on one side inside the mounting frame 12.

[0034] During operation, an eccentric seat 164 is fixed to one end of the support shaft 162 that passes through the fixed seat 161. The eccentric seat 164 rotates synchronously with the support shaft 162. The sliding sleeve 165, which is sleeved on the outside of the eccentric seat 164, also makes a circular motion. The connecting rod 166 fixed at the top of the sliding sleeve 165 drives the rotating sleeve 167 at its top to rotate around the pin 168. The two extension rods 169 passing through the rotating sleeve 167 on both sides make a reciprocating swinging motion around the pin in the rotating seat 1692. The roller 1691 installed at the other end of the extension rod 169 slides in the annular groove 143 opened on the outside of the stop seat 142. While swinging, the extension rod 169 can push the stop seat 142 and the support column 141 to make up-and-down reciprocating motion through the roller 1691 in the annular groove 143. This drives the sliding column 131 and the diamond saw blade at the top to complete the up-and-down reciprocating motion while rotating, thereby automatically simulating the impact action of the diamond saw blade.

[0035] Two inspection doors 17 are installed on the front side of the mounting frame 12, and a ring-shaped collection box 18 is fixedly installed on the testing table 2. The collection box 18 is located below the diamond saw blade. During operation, the ring-shaped collection box 18 fixed on the testing table 2 is located below the diamond saw blade, which can prepare in advance for the collection of saw blade debris during the testing process. The saw blade debris generated during the testing process will naturally fall into the ring-shaped collection box 18 on the testing table 2, which is convenient for subsequent unified cleaning.

[0036] Working principle of this invention:

[0037] Before testing, the center hole of the diamond saw blade is fitted onto the outside of the sliding post 131 of the limiting component 13, so that the bottom of the saw blade overlaps the retaining ring 134 on the sliding post 131, ensuring that the three limiting posts 135 are inserted through into the corresponding holes of the saw blade to achieve circumferential limiting of the saw blade and prevent the saw blade from rotating during the testing process. Then, the clamping nut 133 on the outside of the stud 132 is tightened so that the clamping nut 133 fits tightly with the top of the saw blade, completing the axial clamping and fixing of the saw blade. Through the dual fixing method of mechanical limiting and thread clamping, it is ensured that the saw blade does not loosen or shift during subsequent impact and compound motion, providing a basic guarantee for the testing accuracy. The saw blade is located directly below the base impact-resistant component 10 and below the cutter head impact-resistant component 8.

[0038] By activating two electric hydraulic rods 6, the support box 7 is moved vertically downwards. The support box 7, through four support rods 9, moves the base impact-resistant assembly 10 downwards synchronously, so that the base impact ring 101 is positioned above the base of the diamond saw blade. At this time, there is a gap between the base impact ring 101 and the diamond saw blade, providing sufficient stroke for the diamond saw blade to strike the base impact ring 101 upwards. The blade impact-resistant assembly 8 installed inside the support box 7 moves downwards synchronously with the support box 7, so that the two blade impact brackets 802 of the blade impact-resistant assembly 8 are aligned with the blade head of the diamond saw blade. There is a gap between the blade impact brackets 802 and the blade head of the diamond saw blade, providing sufficient stroke for the blade head of the diamond saw blade to strike the blade impact brackets 802 upwards.

[0039] When conducting impact resistance tests on the cutting heads of diamond saw blades of different specifications, the rotary motor 805 is started, driving the drive gear 804 on its output shaft to rotate synchronously. The drive gear 804 meshes with the transmission gear 803 on the outer side of one of the gear seats 801, thereby driving the gear seat 801 to rotate around its central shaft within the support box 7. Due to the meshing of the two gear seats 801, the rotation of one gear seat 801 drives the other gear seat 801 to rotate synchronously in the opposite direction. The two gear seats 801 respectively drive their respective... The fixedly connected blade impact bracket 802 rotates in an arc around the gear seat 801 as the axis. The arc structure at one end of the blade impact bracket 802 is aligned with the blade head position of the diamond saw blade. When adjusting the position of the detection component 11, the limiting screw 114 at the top of the base impact ring 101 corresponding to the position of the sliding seat 111 is loosened, and the sliding seat 111 is pushed to slide in the slide rails 103 opened on the front and rear sides of the base impact ring 101, so that the sliding seat 111 drives the dial indicator 112 and the detection contact 113 to correspond to the detection position on the surface of the diamond saw blade.

[0040] Next, the drive motor 15 is started, which drives the worm gear 147 on its output shaft to rotate synchronously. The worm gear 147 then drives the stop bar 146 to rotate through the slide bar 145, causing the slide bar 145 to slide in the sliding hole 144 at the bottom of the support column 141. The stop bar 146 slides synchronously in the guide grooves on both sides of the sliding hole 144, thereby driving the stop seat 142 to rotate. The stop seat 142 then drives the slide column 131 to rotate through the support column 141. The slide column 131 drives the diamond saw blade to rotate through the retaining ring 134 and the limiting post 135, thereby simulating the working state of the diamond saw blade. Because the worm gear 147 meshes with the worm wheel 163 outside the support shaft 162, it drives the support shaft 162 to rotate within the fixed seat 161. Because an eccentric seat 164 is fixed at one end of the support shaft 162 that passes through the fixed seat 161, the eccentric seat 164 rotates synchronously with the support shaft 162. The outer side of the eccentric seat 164 is fitted with... The rotating sleeve 165 also makes a circular motion. The connecting rod 166 fixed at the top of the sleeve 165 drives the rotating sleeve 167 at its top to rotate around the pin 168. The two extension rods 169 passing through the rotating sleeve 167 on both sides make a reciprocating swinging motion around the pin in the rotating seat 1692. The roller 1691 installed at the other end of the extension rod 169 slides in the annular groove 143 opened outside the stop seat 142. While swinging, the extension rod 169 can push the stop seat 142 and the support column 141 to make up and down reciprocating motion through the roller 1691 in the annular groove 143. This drives the sliding column 131 and the diamond saw blade at the top to complete the up and down reciprocating motion while rotating. During this process, the stop bar 146 slides synchronously in the guide grooves opened on both sides inside the sliding hole 144, so that the worm gear 147 does not displace, ensuring the stability of the support column 141 driving the diamond saw blade to move.

[0041] During the rotation and reciprocating motion of the diamond saw blade, the two impact holders 802 are designed with an arc shape facing downwards at their far ends. The cutting head of the diamond saw blade directly applies a periodic impact load to the impact holder 802. At the same time, the base in the middle of the diamond saw blade impacts the base impact ring 101, applying a periodic impact load to the base impact ring 101. The speed of the drive motor 15 is adjusted by the control panel 4, thereby changing the frequency of the diamond saw blade's reciprocating motion and simulating the impact intensity on the cutting head and base of the diamond saw blade under different working conditions. When the saw blade is deformed due to the impact of the impact holder 802 and the base impact ring 101 and the force generated by the subsequent combined motion, the detection contact 113 of the dial indicator 112 will produce a small displacement when it contacts the saw blade. The dial indicator 112 can capture this displacement and convert it into an intuitive numerical display, realizing real-time and high-precision monitoring of the deformation and deformation trend after the impact on the base.
