Description

Technical Field

[0001] This invention relates to the field of power tool grease performance testing, and in particular to a multifunctional hammer and pickaxe working condition testing machine. Background Technology

[0002] Electric hammers and electric picks utilize the principle of piston motion, using compressed gas to impact the drill bit. They require minimal manual force and can perform operations such as drilling, breaking, chiseling, digging, grooving, and cutting in hard materials like concrete, brick, and stone. The key to their operation lies in the proper piston motion of the cylinder. The piston motion of the cylinder in electric hammers and electric picks relies on grease for sealing, protection, and wear inhibition. The impact durability of this grease directly determines the tool's lifespan. Therefore, evaluating the impact of cylinder grease on the impact durability of electric picks and electric hammers is particularly important.

[0003] Existing testing machines use a fixed structure to fix power tools (electric hammers or electric picks) to the machine, and then use the power tools to strike stones for testing. The fixed structure on the testing machine mostly adopts a fixed clamp design, which is not convenient for clamping and fixing power tools of different sizes. Summary of the Invention

[0004] To address the issue that the fixed structure on the test frame is inconvenient for clamping and fixing power tools of different sizes, this application provides a multifunctional hammer and pick working condition testing machine.

[0005] The multifunctional hammer and pick working condition testing machine provided in this application adopts the following technical solution: A multifunctional hammer and pick working condition testing machine includes a lower retainer with two support columns. An upper retainer is fixed to the top of the two support columns. A buffer rod is passed through the top surface of the upper retainer, and a mounting rod is fixed to the bottom end of the buffer rod. Slide seats are fixed to both sides of the bottom surface of the mounting rod. A sliding groove is formed on the bottom surface of the slide seat, and a sliding block is slidably disposed in the sliding groove. A chuck for clamping a power tool is fixed to the opposite end face of the two sliding blocks. A driving mechanism for driving the two sliding blocks to move toward each other is provided on the buffer rod. Two sets of fixing components for fixing the body of the power tool are arranged vertically on the support columns.

[0006] By adopting the above technical solution, the top of the power tool is placed between two chucks. The drive mechanism is activated, and the drive mechanism drives two sliding blocks to move the two chucks toward each other, so that the two chucks clamp the top of the power tool. Then, the upper and lower parts of the power tool body are fixed by two sets of fixing components, thereby completing the clamping and fixing of the power tool. Since the distance between the two chucks can be adjusted, it is convenient to clamp and fix power tools of different sizes.

[0007] Preferably, the driving mechanism includes a movable rod sleeved on the buffer rod, the movable rod being slidably connected to the buffer rod in a vertical direction, a connecting rod 1 being rotatably mounted at both ends of the movable rod, a connecting rod 2 being rotatably mounted at both ends of the mounting rod, the top end of the connecting rod 2 being rotatably connected to the bottom end of the connecting rod 1, a connecting rod 3 being rotatably mounted at the bottom end of the connecting rod 2, and the end of the connecting rod 3 away from the connecting rod 2 being hinged to the end of the sliding block away from the clamp, and a fixing member for fixing the movable rod is provided on the buffer rod.

[0008] By adopting the above technical solution, when the top of the power tool is placed between the two chucks, the moving rod is moved downward. When the moving rod moves downward, it drives the first connecting rod to rotate. The bottom end of the first connecting rod drives the second connecting rod to rotate. The bottom end of the second connecting rod pushes the third connecting rod to move. This causes the third connecting rod to push the sliding block to move towards the power tool. The sliding block then drives the chucks to move towards the power tool, thereby clamping the top of the power tool between the two chucks.

[0009] Preferably, the fixing component includes a movable sleeve sleeved on the buffer rod, the movable sleeve being threadedly connected to the buffer rod, the bottom end of the movable sleeve being rotatably mounted on the top surface of the movable rod, and a hexagonal block being sleeved and fixed on the outer circumferential surface of the movable sleeve.

[0010] By adopting the above technical solution, a hexagonal wrench is used to rotate the hexagonal block, causing the hexagonal block to drive the movable sleeve to rotate and move vertically along the buffer rod. This causes the movable sleeve to drive the movable rod to move vertically. When the rotation of the hexagonal block stops, the movable sleeve stops moving, thereby stopping the movement of the movable rod.

[0011] Preferably, each set of fixing components includes fixing blocks disposed on both sides of the power tool. Fixing rods are fixed at both ends of the fixing blocks on the side away from the power tool. Support rods are sleeved on the two fixing rods. The fixing rods are slidably connected to the support rods. A support rod is fixed on the side of the support rod away from the power tool. One end of the support rod away from the support rod is sleeved on the outer circumferential surface of the support rod. A spring is disposed on the periphery of the fixing rod. The two ends of the spring abut against the sides of the support rod opposite to the fixing blocks.

[0012] By adopting the above technical solution, when the top of the power tool is fixed between the two chucks, the fixing blocks on both sides of the power tool move toward the power tool under the elastic force of the spring, thereby clamping the power tool with the fixing blocks on both sides of the power tool.

[0013] Preferably, the support rod is slidably connected to the support column in the vertical direction, a screw is provided on the top surface of the upper retainer, a rotating handle is fixed at the top end of the screw, the bottom end of the screw is rotatably mounted on the top surface of the lower retainer, the screw is rotatably connected to the upper retainer, two connecting plates are sleeved on the screw, the connecting plates are threadedly connected to the screw, and the support rod is fixed to the side of the connecting plate.

[0014] By adopting the above technical solution, when it is necessary to adjust the clamping position of the fixing block on the power tool, the handle is rotated, the handle drives the screw to rotate, the screw drives the connecting rod to move vertically, the connecting rod drives the support rod to move vertically, the support rod and the electric fixing rod move vertically, thereby the fixing rod drives the fixing block to move vertically, and the clamping position of the fixing block on the power tool is adjusted.

[0015] Preferably, a support plate is fixed to the top surface of the lower retainer, a guide groove is provided on the side of the support plate, a guide block is fixed to the side of the connecting rod, and the guide block is slidably disposed in the guide groove along the vertical direction.

[0016] By adopting the above technical solution, when the screw is rotated and the screw drives the connecting rod to move vertically, the guide block on the side of the connecting rod moves vertically in the guide groove, thus making the connecting rod more stable when moving vertically.

[0017] Preferably, the top surface of the upper retainer has a through hole, the buffer rod passes through the through hole, a sliding sleeve is fitted on the outer circumferential surface of the buffer rod, the sliding sleeve is threadedly connected to the buffer rod, the sliding sleeve is inserted into the through hole, a fixing plate is fixed on the outer circumferential surface of the sliding sleeve, and the fixing plate is fixedly connected to the upper retainer by bolts.

[0018] By adopting the above technical solution, when the thickness of the stone being tested is different and the position of the power tool needs to be adjusted, the buffer rod is moved vertically, so that the buffer rod drives the power tool to move vertically. When the position of the power tool is adjusted, the sliding sleeve is rotated so that the bottom end of the sliding sleeve is inserted into the through hole. Then, the fixing plate is fixed to the top surface of the upper retainer by bolts, thereby fixing the buffer rod on the retainer.

[0019] Preferably, the top surface of the lower retainer is fixed with two guide rails, and a bearing seat is slidably disposed on the two guide rails.

[0020] By adopting the above technical solution, the support seat is slidably connected to the guide rail. The stone is placed on the support seat, and by moving the support seat, the support seat moves the stone, which facilitates hammering tests on different positions of the stone.

[0021] Preferably, a fixing seat is fixed on both sides of the top surface of the bearing seat, a tightening rod is provided through the side of the fixing seat, the tightening rod is threaded to the fixing seat, and a rotating block is fixed on the end face of the tightening rod away from the fixing seat.

[0022] By adopting the above technical solution, when the test stone is placed on the support, the hexagonal wrench is inserted into the hexagonal groove. When the hexagonal wrench is rotated, the hexagonal wrench drives the tightening rod to rotate, so that the tightening rod moves towards the stone, thereby clamping the test stone with the tightening rods on both sides of the stone.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. Place the top of the power tool between the two chucks, start the drive mechanism, and the drive mechanism will drive the two sliding blocks to move the two chucks toward each other, so that the two chucks clamp the top of the power tool. Then, the upper and lower parts of the power tool body are fixed by two sets of fixing components, thus completing the clamping and fixing of the power tool. Since the distance between the two chucks can be adjusted, it is convenient to clamp and fix power tools of different sizes. 2. When the top of the power tool is placed between the two chucks, move the moving rod downwards. As the moving rod moves downwards, it drives the first connecting rod to rotate. The bottom end of the first connecting rod drives the second connecting rod to rotate. The bottom end of the second connecting rod pushes the third connecting rod to move. This causes the third connecting rod to push the sliding block to move towards the power tool. The sliding block then drives the chucks to move towards the power tool, thereby clamping the top of the power tool between the two chucks. 3. When the thickness of the stone being tested is different and the position of the power tool needs to be adjusted, move the buffer rod vertically so that the buffer rod drives the power tool to move vertically. When the position of the power tool is adjusted, rotate the sliding sleeve so that the bottom end of the sliding sleeve is inserted into the through hole. Then, fix the fixing plate to the top surface of the upper retainer with bolts, thereby fixing the buffer rod to the retainer. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] This application discloses a multifunctional hammer and pick working condition testing machine.

[0032] Reference Figure 1 and Figure 2 As shown, a multifunctional hammer and pick working condition testing machine includes a lower retainer 1. Support columns 11 are provided at both ends of the top surface of the lower retainer 1, and an upper retainer 12 is fixed to the top of the two support columns 11. A through hole 13 is opened on the top surface of the upper retainer 12, and a buffer rod 14 passes through the through hole 13. A sliding sleeve 15 is fitted onto the outer circumferential surface of the buffer rod 14, and the sliding sleeve 15 is threadedly connected to the buffer rod 14. The sliding sleeve 15 is inserted into the through hole 13, and a fixing plate 16 is fixed to the outer circumferential surface of the sliding sleeve 15. The fixing plate 16 is fixedly connected to the upper retainer 12 by bolts.

[0033] Reference Figure 1 , Figure 2 and Figure 3A horizontally mounted mounting rod 2 is fixed to the bottom end of the buffer rod 14. Slide seats 21 are fixed to both sides of the bottom surface of the mounting rod 2. A sliding groove 22, which is a T-shaped groove, is formed on the bottom surface of the slide seat 21. A sliding block 23 is slidably mounted within the sliding groove 22. A chuck 24 for holding a power tool is fixed to the opposite end faces of the two sliding blocks 23. A horizontally mounted movable rod 25 is fitted onto the outer circumference of the buffer rod 14. The movable rod 25 is slidably connected to the buffer rod 14 vertically. A movable sleeve 26 is fitted onto the outer circumference of the buffer rod 14 and is threadedly connected to the buffer rod 14. The bottom end of the movable sleeve 26 is rotatably mounted on the top surface of the movable rod 25. A hexagonal block 261 is fixedly fitted onto the outer circumference of the movable sleeve 26. Both ends of the movable rod 25 are rotatably mounted with connecting rod 1 27, and both ends of the mounting rod 2 are rotatably mounted with connecting rod 22 28. The top end of connecting rod 22 28 is rotatably connected to the bottom end of connecting rod 1 27. The bottom end of connecting rod 22 28 is rotatably mounted with connecting rod 3 29, and the end of connecting rod 3 29 away from connecting rod 22 28 is hinged to the end of sliding block 23 away from clamp 24.

[0034] Place the top of the power tool between the two chucks 24, rotate the hexagonal block 261, the hexagonal block 261 drives the movable sleeve 26 to rotate, and the movable sleeve 26 moves downward as it rotates. The movable sleeve 26 drives the movable rod 25 to move downward. When the movable rod 25 moves downward, the movable rod 25 drives the first connecting rod 27 to rotate, the first connecting rod 27 drives the second connecting rod 28 to rotate, the second connecting rod 28 drives the third connecting rod 29 to rotate, and the third connecting rod 29 drives the sliding block 23 to move. The sliding block 23 drives the chucks 24 to move towards the power tool, so that the chucks 24 on both sides of the power tool clamp the top of the power tool.

[0035] Reference Figure 1 and Figure 4 Two support rods 3 are fitted onto the outer circumferential surfaces of the two support columns 11. A support rod 31 is fixed to the end of each support rod 3 away from the support column 11. A fixing block 32 for clamping a power tool is provided on the side of the support rod 31 away from the support rod 3. Fixing rods 33 are fixed to both ends of the fixing block 32 near the support rod 31. The end of the fixing rod 33 away from the fixing block 32 passes through the support rod 31, and the fixing rod 33 is slidably connected to the support rod 31. A limit block 34 is fixed to the end of the fixing rod 33 away from the fixing block 32. A spring 35 is fitted onto the outer circumferential surface of the fixing rod 33, and both ends of the spring 35 abut against the opposite sides of the fixing block 32 and the support rod 31.

[0036] The power tool is placed between two opposing fixed blocks 32. The fixed blocks 32 move toward the power tool under the elastic force of the spring 35. The fixed blocks 32 on both sides of the power tool hold the power tool, thereby improving the stability of the power tool.

[0037] Reference Figure 1 and Figure 4 A screw 4 is threaded through the top surface of the upper retainer 12, and the screw 4 is rotatably connected to the upper retainer 12. A handle 41 is fixed to the top end of the screw 4, and the bottom end of the screw 4 is rotatably mounted on the top surface of the lower retainer 1. Two connecting plates 42 are sleeved on the outer circumference of the screw 4, and the end faces of two opposing support rods 31 on the two support columns 11 are fixed to the side of the connecting plates 42. A support plate 43 is fixed to the top surface of the lower retainer 1, and two guide grooves 44 are opened on the side of the support plate 43. Two guide blocks 45 are fixed to the side of the connecting plate 42 away from the support rods 31, and the two guide blocks 45 are respectively slidably disposed in the two guide grooves 44 along the vertical direction.

[0038] Rotating the handle 41 causes the screw 4 to rotate, which in turn drives the connecting plate 42 to move vertically. The connecting plate 42 then drives the support rod 31 to move vertically, which in turn drives the fixing rod 33 to move vertically. The fixing rod 33 then drives the fixing block 32 to move vertically, thereby adjusting the clamping position of the fixing block 32 on the power tool.

[0039] Reference Figure 1 and Figure 5 The lower retainer 1 has two parallel guide rails 5 fixed inside, and a support seat 51 for placing the test stone is slidably mounted on the two guide rails 5. A fixing seat 52 is fixed to both sides of the top surface of the support seat 51. Two clamping rods 53 for clamping the test stone are threaded through the sides of the fixing seat 52. The clamping rods 53 are threaded to the fixing seat 52, and a rotating block 54 is fixed to the end of the clamping rod 53 away from the test stone.

[0040] The implementation principle of a multifunctional hammer and pick working condition testing machine in this application embodiment is as follows: the stone to be tested is placed on the support platform, and then the rotating blocks 54 on both sides of the top surface of the support platform are rotated, so that the rotating blocks 54 drive the clamping rod 53 to rotate, so that the clamping rod 53 clamps the test stone to the top surface of the support platform.

[0041] The top of the power tool is placed between the two chucks 24. By rotating the handle 41, the handle 41 drives the screw 4 to rotate. The screw 4 drives the two connecting plates 42 to move vertically. The connecting plates 42 drive the support rod 31 to move. The support rod 31 drives the fixing rod 33 to move vertically. The fixing rod 33 drives the fixing block 32 to move vertically, thereby adjusting the clamping position of the fixing block 32 on the power tool. After the clamping position of the fixing block 32 on the power tool is adjusted, the fixing block 32 moves towards the power tool under the elastic force of the spring 35, thereby clamping the power tool with the fixing blocks 32 on both sides of the power tool.

[0042] Then, by rotating the hexagonal block 261 with a hexagonal wrench, the hexagonal block 261 drives the movable sleeve 26 to rotate and move downwards. The movable sleeve 26 drives the movable rod 25 to move downwards. When the movable rod 25 moves downwards, the connecting rod 1 27 at both ends of the movable rod 25 rotates. The connecting rod 1 27 drives the connecting rod 28 to rotate. The connecting rod 28 drives the connecting rod 3 29 to rotate. The connecting rod 3 29 drives the sliding block 23 to move towards the power tool. The sliding block 23 drives the chuck 24 to move towards the power tool. This allows the chucks 24 on both sides of the power tool to clamp the top of the power tool. Since the distance between the two chucks 24 is adjustable, it is convenient for the two chucks 24 to clamp and fix power tools of different sizes, fixing the power tool above the test stone, thus facilitating the power tool to perform a tapping test on the test stone.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
