Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and in particular relates to a saw blade back grinding machine. Background Technology

[0002] In the saw blade manufacturing industry, the performance of a saw blade largely depends on the straightness and smoothness of its back surface, as this directly affects the cutting quality and durability of the saw blade. Traditionally, the back of the saw blade is polished manually or with simple grinding tools, a method that is extremely inefficient. With advancements in machinery, specialized equipment for polishing the back of saw blades has emerged, significantly increasing the speed of the polishing process.

[0003] Existing saw blade back grinders grind the saw blade by placing it inside the grinder. However, during the grinding process, the saw blade may shift, affecting the efficiency and accuracy of the grinder.

[0004] In other words, if the saw blade shifts during the grinding process of a traditional saw blade back grinder, it will affect the grinding effect of the machine and reduce the precision of the grinding process. Utility Model Content

[0005] This utility model addresses the problem in existing saw blade back grinders where saw blade misalignment during grinding affects the grinding effect and reduces the precision of the grinding process. The following technical solution is proposed:

[0006] A saw blade back grinding machine, comprising:

[0007] A grinding frame, equipped with a protective cover, is used to grind the weld area of ​​the saw blade;

[0008] A movable component is provided with a grinding element, and the movable component is connected to the grinding machine frame;

[0009] A clamping assembly, connected to the grinding frame, is used to prevent the saw blade being ground from slipping down;

[0010] A dust collection assembly is provided with a collection member. The dust collection assembly is connected to the grinding machine frame, and the collection member is located below the grinding machine.

[0011] An oil-absorbing component, connected to the clamping component, is used to remove residual oil stains from the polished saw blade.

[0012] As a preferred embodiment of the above technical solution, the moving component includes a fixed shaft, a driving component, a linkage component, a lead screw, a slide groove, and a moving component. Three driving components are provided. One driving component drives the grinding part to rotate via the fixed shaft. Another driving component drives the lead screw to rotate via the linkage component. One driving component is threadedly connected to the outer surface of the lead screw via a mounting plate. The rotation of the lead screw causes one of the driving components to move vertically along the slide groove. The driving component, the linkage component, the lead screw, and the slide groove are all mounted on the top of the moving component via the same mounting bracket. The last driving component drives the mounting bracket to move horizontally.

[0013] As a preferred embodiment of the above technical solution, the clamping assembly includes an air compressor, a moving block, an extrusion component, and a bearing. The air compressor pushes the moving block to move towards the extrusion component. The saw blade is placed between the moving block and the extrusion component. The bearing is interference-fitted to the bottom of the moving block, and the saw blade is located at the top of the bearing to prevent the saw blade from falling off.

[0014] As a preferred embodiment of the above technical solution, the dust collection assembly includes a mounting frame and a transmission pipe, the transmission pipe being connected to the collecting component, and the collecting component being connected to the grinding machine frame via the mounting frame.

[0015] As a preferred embodiment of the above technical solution, the oil suction assembly includes an oil suction box, an oil suction component, and a mounting block. The oil suction component rotates inside the oil suction box, and one end face of the oil suction component is in contact with the saw blade. The oil suction box is connected to the moving block through the oil suction component and is used to clean the grease (cutting fluid used to cool the saw blade) on the saw blade.

[0016] As a preferred embodiment of the above technical solution, the linkage is composed of the saw gear and the saw rack.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) The saw blade is pressed by the cooperation of the moving block and the pressing part, and the saw blade is restricted by the bearing, so that the device can grind the saw blade more stably, thereby avoiding the problem of deviation during the grinding process of the saw blade, thus improving the accuracy and effect of grinding the saw blade.

[0019] (2) The debris (particles generated during saw blade grinding) generated during saw blade grinding is collected by the collection component, which avoids the accumulation of debris (particles generated during saw blade grinding) on ​​the surface of the grinding machine frame, thereby avoiding the problem of these debris (particles generated during saw blade grinding) causing wear on the surface of the grinding machine frame, thus extending the service life of the equipment.

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] Example 1

[0029] This utility model provides a saw blade back grinding machine, such as Figures 1 to 6As shown, it includes: a grinding frame 1, a moving assembly 3, a clamping assembly 4, a dust extraction assembly 5, and an oil extraction assembly 6. The clamping assembly 4 is equipped with a mounting bracket and is mounted on the grinding frame 1 via the mounting bracket. The grinding frame 1 is equipped with a protective cover 2. The grinding frame 1 is used to grind the weld seam area of ​​the saw blade. The moving assembly 3 is equipped with a grinding element 31, which is a full-blown braided wheel. The moving assembly 3 is connected to the grinding frame, and the clamping assembly 4 is connected to the grinding frame and is used to prevent... To prevent the saw blade from sliding down during grinding, the dust collection assembly 5 is equipped with a collection component 51. The dust collection assembly 5 is connected to the grinding machine frame, and the collection component 51 is located below the grinding component 31. The oil suction assembly 6 is connected to the clamping assembly 4 and is used to remove residual oil stains on the saw blade after grinding. The moving assembly 3 includes a fixed shaft 32, a drive component 33, a linkage component 34, a lead screw 35, a slide rail 36, and a moving component 37. The drive component 33 is a 400-watt servo motor, and the moving component 37 is an electric slide rail. There are three drive components 33. One drive component 33 drives the grinding component 31 to rotate via the fixed shaft 32. Another drive component 33 drives the lead screw 35 to rotate via the linkage component 34. One drive component 33 is threadedly connected to the outer surface of the lead screw 35 via the mounting plate. The rotation of the lead screw 35 drives one of the drive components 33 to move vertically along the slide groove 36. The drive component 33, linkage component 34, lead screw 35 and slide groove 36 are all mounted on the top of the moving component 37 via the same mounting bracket. The last drive component 33 drives the mounting bracket to move horizontally. The clamping assembly 4 includes an air compressor 41, a moving block 42, an extrusion component 43 and a bearing 44. The bearing 44 is made of ceramic. The air compressor 41 pushes the moving block 42 to move towards the extrusion component 43. The saw blade is placed between the moving block 42 and the extrusion component 43. The bearing 44 is interference-fitted to the bottom of the moving block 42 and the saw blade is located on top of the bearing 44 to prevent the saw blade from falling off. The linkage component 34 is composed of a saw gear and a saw toothed rack.

[0030] The saw blade is pressed together by the cooperation of the moving block 42 and the pressing part 43, and the saw blade is restricted by the bearing 44, so that the device can grind the saw blade more stably, thereby avoiding the problem of deviation during the grinding process and improving the accuracy and effect of grinding the saw blade.

[0031] In use, the operator first places the saw blade between the moving block 42 and the pressing component 43, and then places the saw blade on top of the bearing 44. Next, the air compressor 41 is started, pushing the moving block 42 towards the pressing component 43, causing the moving block 42 to move the saw blade synchronously. The moving block 42, in conjunction with the saw blade, presses and positions the saw blade. Then, the operator starts one of the drive components 33, which, via the fixed shaft 32, drives the grinding component 31 to grind the surface of the saw blade. Then, the operator starts the other drive component 33, which, via the linkage 34, drives the lead screw 35 to rotate. During this rotation, the lead screw 35 causes one of the drive components 33 to move along the slide groove 36. The device moves horizontally to adjust the height of the grinding component 31. The last drive component 33 drives the moving component 37 to move, causing the moving component 37 to move the grinding component 31, fixed shaft 32, and other equipment horizontally to adjust the position of the grinding component 31. When the grinding component 31 grinds the saw blade, the splashed debris (particles generated during saw blade grinding) is blocked by the protective cover 2. The saw blade is pressed tightly by the cooperation of the moving block 42 and the pressing component 43, and the saw blade is restricted by the bearing 44, making the device grind the saw blade more stably, thus avoiding the problem of deviation during saw blade grinding, thereby improving the accuracy and effect of saw blade grinding.

[0032] Specifically, two protective covers 2 are bolted to the top of the grinding machine frame 1. One of the protective covers 2 houses a movable component 37 fixed to the top of the grinding machine frame 1. A linkage component 34 is fixedly connected to the top of the movable component 37 via a mounting bracket. A lead screw 35 is fixedly connected to one end of the linkage component 34. Both the movable component 37 and the linkage component 34 are equipped with driving components 33. One driving component 33 is fixedly connected to the top of the grinding machine frame 1, while the other driving component 33 is fixedly installed inside the mounting bracket. A sliding groove 3 is provided inside the mounting bracket. 6. A drive component 33 that slides inside a slide groove 36 is installed on the outer surface of the lead screw 35 by means of a threaded connection. A grinding component 31 is installed at the output end of the drive component 33 through a fixed shaft 32. An air compressor 41 is fixed to the top of the grinding machine frame 1 inside another protective cover 2. A moving block 42 is installed at the output end of the air compressor 41 by means of a threaded connection. A bearing 44 is installed at the bottom of the moving block 42. An extrusion component 43 is fixedly installed on the grinding machine frame 1, and the extrusion component 43 is aligned horizontally with the moving block 42.

[0033] To address the issue of collecting the debris (particles generated during saw blade grinding) as described in the above example, the following solution is proposed: Figure 2 , Figure 5 and Figure 6As shown, the dust collection assembly 5 includes a mounting bracket 52 and a transmission pipe 53. The transmission pipe 53 is connected to a collection member 51, which is a tapered tube. The collection member 51 is connected to the grinding machine frame 1 via the mounting bracket 52. The other end of the transmission pipe 53 is embedded inside the vacuum cleaner, which is installed inside the grinding machine frame 1. A filter screen is provided inside the transmission pipe 53 to prevent saw chips from entering the vacuum cleaner and causing damage. The oil suction assembly 6 includes an oil suction box 61. The oil-absorbing component 62 and the mounting block 63 are used to clean the grease (cutting fluid used to cool the saw blade) on the saw blade. The oil-absorbing component 62 is made of polypropylene (PP) absorbent cotton and rotates inside the oil-absorbing box 61. One end of the oil-absorbing component 62 is in contact with the saw blade. A micro motor is fixed inside the oil-absorbing box 61 on the oil-absorbing component 62. A scraper is provided on the oil-absorbing box 61 and the outer surface of the oil-absorbing component 62 is in contact with the scraper. The oil-absorbing box 61 is connected to the moving block 42 through the oil-absorbing component 62. It is used to clean the grease (cutting fluid used to cool the saw blade) on the saw blade.

[0034] The collecting component 51 collects the debris (particles generated during saw blade grinding), preventing the debris (particles generated during saw blade grinding) from accumulating on the surface of the grinding frame 1. This avoids the problem of these debris (particles generated during saw blade grinding) causing wear on the surface of the grinding frame 1, thereby extending the service life of the equipment.

[0035] During use, when the grinding element 31 grinds the saw blade, the resulting debris (particles generated during saw blade grinding) is first blocked by the protective cover 2. Then, these debris (particles generated during saw blade grinding) fall downwards into the collection unit 51. At this time, the operator starts a vacuum cleaner, which absorbs the impurities that have fallen into the collection unit 51. These impurities then travel along the collection unit 51 into the transmission pipe 53, where a filter screen blocks the debris (particles generated during saw blade grinding) from the saw blade, preventing damage to the vacuum cleaner's internal components. The debris is then collected inside the vacuum cleaner through the transmission pipe 53. While the grinding element 31 grinds the saw blade, the oil suction element 62 removes oil from the surface of the saw blade. The oil (cutting fluid used to cool the saw blade) on the surface is absorbed. Then, the operator starts the micro motor to drive the oil suction component 62 to rotate. When the oil suction component 62 rotates, it scrapes the oil (cutting fluid used to cool the saw blade) on the surface of the oil suction component 62 and collects it under the restriction of the oil suction box 61. Finally, the operator cleans the oil (cutting fluid used to cool the saw blade) inside the oil suction box 61. The debris (particles generated during saw blade grinding) generated during saw blade grinding is collected by the collection component 51, which avoids the accumulation of debris (particles generated during saw blade grinding) on ​​the surface of the grinding machine frame 1, thereby avoiding the problem of these debris (particles generated during saw blade grinding) wearing down the surface of the grinding machine frame 1, thus extending the service life of the equipment.

[0036] Specifically, a fixed frame 52 is fixedly connected to the top of the grinding machine frame 1 at a position below the grinding part 31. A collection part 51 is fixedly connected inside the fixed frame 52 by screws. A transmission pipe 53 is embedded inside the collection part 51, and the other end of the transmission pipe 53 is embedded and connected to a vacuum cleaner installed inside the grinding machine frame 1. An installation block 63 is installed on the moving block 42 by screws. An oil suction box 61 is fixedly connected to the top of the installation block 63. An oil suction part 62 is rotatably connected inside the oil suction box 61.

[0037] Working principle: When using this device, the operator first places the saw blade between the moving block 42 and the pressing component 43, and then places the saw blade on top of the bearing 44. Next, the air compressor 41 is started, pushing the moving block 42 towards the pressing component 43, causing the moving block 42 to move the saw blade synchronously. The moving block 42, in conjunction with the pressing component 43, presses and positions the saw blade. Then, the operator starts one of the driving components 33, which, through the fixed shaft 32, drives the grinding component 31 to grind the surface of the saw blade. Subsequently, the operator starts the other driving component 33, which, through the linkage 34, drives the lead screw 35 to rotate. During this rotation, the lead screw 35 drives one of the driving components 33 along the sliding path... The groove 36 moves horizontally to adjust the height of the grinding component 31. The last drive component 33 drives the moving component 37 to move, so that the moving component 37 drives the grinding component 31, fixed shaft 32 and other equipment to move horizontally to adjust the position of the grinding component 31. When the grinding component 31 grinds the saw blade, the splashed debris (particles generated when grinding the saw blade) is blocked by the protective cover 2. The saw blade is pressed by the cooperation of the moving block 42 and the pressing component 43, and the saw blade is restricted by the bearing 44, so that the device grinds the saw blade more stably, thereby avoiding the problem of deviation during the grinding process, thus improving the accuracy and effect of grinding the saw blade.

[0038] When the grinding part 31 grinds the saw blade, the resulting debris (particles generated during saw blade grinding) is first blocked by the protective cover 2. Then, these debris (particles generated during saw blade grinding) fall downwards into the collection part 51. At this time, the operator starts a vacuum cleaner, which sucks up the impurities that have fallen into the collection part 51. These impurities then travel along the collection part 51 into the transmission pipe 53, where the filter screen inside the transmission pipe 53 blocks the debris (particles generated during saw blade grinding), preventing damage to the vacuum cleaner's internal components. The debris is then collected inside the vacuum cleaner through the transmission pipe 53. While the grinding part 31 grinds the saw blade, the oil suction part 62 removes oil from the saw blade surface. The grease (cutting fluid used to cool the saw blade) is adsorbed. Then, the operator starts the micro motor to drive the oil suction component 62 to rotate. When the oil suction component 62 rotates, it scrapes the grease (cutting fluid used to cool the saw blade) on the surface of the oil suction component 62 and collects it under the restriction of the oil suction box 61. Finally, the operator cleans the grease (cutting fluid used to cool the saw blade) inside the oil suction box 61. The debris (particles generated during saw blade grinding) generated during saw blade grinding is collected by the collection component 51, which avoids the accumulation of debris (particles generated during saw blade grinding) on ​​the surface of the grinding machine frame 1, thereby avoiding the problem of these debris (particles generated during saw blade grinding) wearing down the surface of the grinding machine frame 1, thus extending the service life of the equipment.
