Description

Technical Field

[0001] The present application relates to the field of grinding technology, and more specifically, to a grinding machine auxiliary bracket and a grinding method thereof. Background Art

[0002] When using a grinder to polish metal or other materials, the grinder must hold the grinder for extended periods, which can lead to hand fatigue and soreness, reducing polishing quality and work efficiency. A related technique, using a single elastic cord to attach the grinder, reduces the labor burden. However, this requires resisting the elastic cord's contraction force when polishing at different heights, which is laborious. Summary of the Invention

[0003] In order to improve the problem that when using a grinder to grind metal or other material devices, the grinder has to hold the grinder with his hands for a long time, which easily causes fatigue and soreness in the hands, thereby reducing the grinding quality and work efficiency, the present application proposes a grinder auxiliary bracket and a grinding method thereof to reduce the burden of the grinder in grabbing the grinder.

[0004] In a first aspect, the present application proposes a grinder auxiliary bracket and adopts the following technical solution.

[0005] A grinding machine auxiliary bracket comprises a supporting mechanism, and a dynamic mechanism, a static mechanism and a suspension mechanism fixed on the supporting mechanism.

[0006] The suspension mechanism includes a telescopic section, a positioning section, a swing section and a connector for installing a grinder, which are connected in sequence; one end of the telescopic section away from the positioning section is fixed to the support mechanism.

[0007] The dynamic mechanism includes a resilient member and a rotating end head connected to each other, and the resilient member is fixed to the supporting mechanism.

[0008] The resilient member pushes the rotating end head toward the static mechanism to fix it, and can bind the positioning section between the rotating end head and the static mechanism.

[0009] The positioning section is configured to engage with the rotating end head, so that when the rotating end head leaves the static mechanism, the movement of the positioning section can drive the rotating end head to rotate, and when the rotating end head is fixed, the positioning section is fixed accordingly.

[0010] By adopting the above technical solution, the rotating end head can be fixed relative to the static mechanism, and the positioning section can be constrained between the rotating end head and the static mechanism, thereby restricting the grinder to a certain height. Because the positioning section is embedded in the rotating end head, it provides a mechanism to drive the rotating end head to rotate to adjust the positioning section's height, or to be restricted by the rotating end head and unable to move up and down. This allows for convenient adjustment of the grinder's height, eliminating the need to resist the contraction force of the telescopic section when grasping the grinder. This is more labor-saving than the method of hanging a single elastic rope to connect the grinder. When the height of the grinder needs to be adjusted, the grinder only needs to be pulled sideways so that the positioning section presses the rotating end head, the resilient member is compressed, and the rotating end head is separated from the static mechanism. Then, the grinder is pulled downward or the pulling force on the grinder is reduced, and the grinder can move up and down. After the lateral pulling force is removed, the grinder is fixed, so that the grinder can be adjusted to the appropriate grinding height in real time. This operation method is more labor-saving, allowing the grinder to maintain a good working state, which is conducive to maintaining the grinding quality and work efficiency. When the rotating end head is engaged with the static mechanism, the elastic force of the resilient member can be set to 10~50N according to needs, such as 20N, 30N, 40N, so that the rotating end head and the static mechanism will not be easily separated during the grinding process.

[0011] As an improvement to the auxiliary bracket of the grinder, the rotating end head includes a middle sprocket, and a first left gear and a first limit member located on both end surfaces of the middle sprocket; the first left gear and the middle sprocket are coaxially fixed; the diameter of the middle sprocket is smaller than the diameter of the first left gear and the radial dimension of the first limit member; the positioning section is a chain that can be engaged with the middle sprocket.

[0012] The static mechanism includes a central convex part and a second left gear located on one side of the central convex part; the second left gear is fixed to the supporting mechanism.

[0013] When the rotating end is pushed toward the static mechanism: the first left gear engages with the second left gear; the middle protrusion is inserted between the first left gear and the first limiting member, and limits the positioning section to a position engaged with the middle sprocket.

[0014] By adopting the above technical solution, the positioning segment is a chain that can be engaged with the middle sprocket, and the positioning segment is confined between the first left gear and the first limiting member. Even when the rotating end leaves the static mechanism, the positioning segment is not easy to slide out. Since the first left gear and the middle sprocket are coaxially fixed, and the second left gear is fixed to the support mechanism, the middle sprocket is synchronously fixed after the first left gear is engaged and fixed by the second left gear. At the same time, the middle convex member binds the positioning segment to the middle sprocket, and the positioning segment is also fixed accordingly, preventing the positioning segment from sliding, keeping the grinder at the required height, and facilitating grinding. The second left gear is fixed to the support mechanism, which can be fixed directly or indirectly. For example, one way is that the second left gear is fixed to the middle convex member, and the middle convex member is fixed to the support mechanism.

[0015] As an improvement to the auxiliary bracket of the grinder, the first limiting member is a first right gear; the first left gear and the first right gear have the same number of teeth and diameter, and are both coaxially fixed to the middle sprocket.

[0016] The static mechanism further includes a second right gear; the second right gear is located on the other side of the middle convex part; the second left gear and the second right gear have the same number of teeth and diameter and are coaxially fixed.

[0017] When the rotating end head is pushed toward the static mechanism, the first right gear engages with the second right gear.

[0018] By adopting the above technical solution, the first limiting member is set to be the first right gear with the same number of teeth and diameter as the first left gear, and is coaxially fixed, meshing with the second left gear and the second right gear respectively, thereby increasing the symmetry of the structure, making the meshing more accurate, and improving the rotational stability and service life of the structure.

[0019] As an improvement to the auxiliary bracket of the grinder, the middle convex part is fixed to the supporting mechanism; the middle convex part has a blocking plane facing the middle sprocket; when the rotating end is pushed toward the static mechanism: the blocking plane limits the positioning section so that the positioning section is in a position embedded in the middle sprocket.

[0020] By adopting the above technical solution, the positioning section is limited by a blocking plane, the blocking area is large, and there is a greater blocking effect on the positioning section, thereby improving the firmness of the positioning section embedded in the middle sprocket, so that the positioning section can drive the middle sprocket to rotate, or be restricted from moving together with the middle sprocket, so that the height control of the grinder is more precise.

[0021] As an improvement to the auxiliary bracket of the grinder, the central convex part is disc-shaped; the central convex part is coaxial with the second left gear, but can rotate relative to the second left gear.

[0022] By adopting the above technical solution, a rotatable disc-shaped central convex part is provided, which also has a good limiting effect on the positioning section, especially the rotatable manner, so that the central convex part can have multiple positions to press against the positioning section, so that the friction and wear of the central convex part are uniform and small, thereby improving the service life of the central convex part.

[0023] As an improvement to the auxiliary support of the grinder, the telescopic section includes a straight elastic member and / or a scroll elastic member.

[0024] By adopting the above technical solution, the straight elastic member and / or the scroll elastic member can have good resilience in the stretched state, thereby tending to pull the positioning section upward, providing a power source for the upward movement of the positioning section.

[0025] As an improvement to the auxiliary bracket of the grinder, the straight elastic member is a straight spring or an elastic rope.

[0026] By adopting the above technical solution, the straight spring or elastic rope has a rebound force when it is in a stretched state, which can provide power for the upward movement of the positioning section. Since the rebound direction is similar to the upward movement direction of the grinder, its rebound force is large, the speed of adjusting the height of the grinder is fast, and it is convenient to use.

[0027] As an improvement to the auxiliary bracket of the grinder, the connecting piece is an elastic ring structure with a width of 3 to 8 cm; when the elastic ring structure is in a naturally stretched state, its diameter is smaller than the diameter of the grinder body; and the elastic ring structure can be placed on the grinder after being stretched.

[0028] By adopting the above technical solution, the connecting piece can be firmly placed on the grinder, and the wider width of 3 to 8 cm helps to improve the stability of the grinder in the air and reduce the degree of shaking after the grinder is out of hand.

[0029] Secondly, this application proposes a polishing method and adopts the following technical solution.

[0030] A grinding method is provided, wherein the grinding method is performed using the grinding machine auxiliary support as described above; the grinding method comprises:

[0031] Install the grinder on the connecting piece and adjust the height of the grinder according to the position of the workpiece to be grinded, including:

[0032] When the current height of the grinder is suitable for the grinding position, the height of the grinder is not adjusted;

[0033] When the height of the current grinder does not match the grinding position, the grinder is pulled sideways so that the positioning section presses the rotating end head laterally, and the rebound member is compressed, so that the rotating end head leaves the static mechanism. The grinder is pulled downward or upward to the required height, and then the force pulling the grinder sideways is reduced or withdrawn, so that the rotating end head moves to the static mechanism and is fixed, and the height of the grinder is fixed synchronously.

[0034] By adopting the above technical solution, when the height of the grinder needs to be adjusted, it is only necessary to pull the grinder sideways so that the rotating end leaves the static mechanism, and then pull down or reduce the pulling force on the grinder. As a result, under the combined action of manual pulling force and the rebound force of the telescopic section, the grinder moves downward or upward, and the rotating end also rotates synchronously. The downward or upward distance can be adjusted in a large range as needed, so that the grinder can be continuously adjusted to a variety of heights. After adjusting the height, the force of pulling the grinder sideways is canceled or reduced, so that the rotating end is docked with the static mechanism and fixed, and the positioning section is fixed.

[0035] Compared with the method of suspending the grinder with a single elastic rope, which requires manual pulling of the grinder to the required grinding height and continuous application of tension, when using this auxiliary bracket for grinding, it is only necessary to apply tension when the height needs to be adjusted. After adjusting the height, during the continuous grinding process, there is no need for manual continuous application of tension to counteract the retraction force of the telescopic section, making the grinding work more labor-saving and efficient.

[0036] As an improvement to the grinding method, the connecting piece is installed at the center of gravity of the grinding machine.

[0037] By adopting the above technical solution, the control force required by the human hand to apply to the grinder is smaller, so that the use of the grinder is more labor-saving. When the grinder is released, the grinder can also be suspended in the air in a relatively balanced manner, thereby improving safety.

[0038] In summary, the grinding machine auxiliary bracket and grinding method thereof of the present application have the following beneficial effects:

[0039] Since the positioning section is embedded in the rotating end head, it has a mechanism that drives the rotating end head to rotate to adjust the height of the positioning section or is restricted by the rotating end head and cannot move up and down. The height of the grinder can be easily adjusted, so when grabbing the grinder, there is no need to resist the contraction force of the telescopic section. Compared with the method of hanging a single elastic rope to connect the grinder, it is more labor-saving.

[0040] When the height of the grinder needs to be adjusted, it is only necessary to pull the grinder sideways, then pull down or reduce the pulling force on the grinder, and keep the rotating end head away from the static mechanism. Under the combined action of the manual pulling force and the rebound force of the telescopic section, the grinder moves downward or upward, and the rotating end head also rotates synchronously. The downward or upward distance can be adjusted relatively arbitrarily, so that the grinder can be continuously adjusted to a variety of heights that need to be grinded. After adjusting the height, since the positioning section is fixed, there is no need for manual pulling to counteract the retraction force of the telescopic section, making the grinding work labor-saving and efficient.

DETAILED DESCRIPTION

[0049] Some embodiments of the grinder auxiliary bracket and the grinding method thereof of the present application are described in detail below with reference to the accompanying drawings.

[0050] See also Figure 1The invention discloses a grinding machine auxiliary bracket, which can suspend a handheld grinding machine 6 to reduce the labor burden of the grinding personnel. The auxiliary bracket can adjust the height of the grinding machine 6 in real time, which is labor-saving and convenient.

[0051] See also Figure 2 The grinding machine auxiliary bracket includes a supporting mechanism 1, and a dynamic mechanism 2, a static mechanism 3 and a suspension mechanism 4 fixed on the supporting mechanism 1.

[0052] The supporting mechanism 1 may be a bracket, such as an inverted L-shaped bracket. The auxiliary bracket of the grinding machine may further include a base 5 , and the supporting mechanism 1 is fixed on the base 5 .

[0053] See also Figure 3 The suspension mechanism 4 may include a telescopic section 401, a positioning section 402, and a connector 403 for mounting the grinder 6, which are connected in sequence. The end of the telescopic section 401 away from the positioning section 402 is fixed to the support mechanism 1. The positioning section 402 may be directly connected to the connector 403. Optionally, the suspension mechanism 4 may further include a hem section 404, which is connected between the positioning section 402 and the connector 403. The hem section 404 may be a flexible section, such as a braided rope, preferably a rubber belt with a certain elasticity, which may also apply a certain tension during grinding to obtain a certain amount of movement space, thereby increasing the flexibility of the device.

[0054] Alternatively, the dynamic mechanism 2 and the static mechanism 3 can be positioned laterally opposite each other, allowing them to dock with each other through internal force, thereby clamping or restraining the vertical positioning section 402 of the suspension mechanism 4 to maintain the height of the grinder 6. The dynamic mechanism 2 can also be driven away from the static mechanism 3 by an external force. In this case, by applying a pulling force to the grinder 6, the combined action of the pulling force and the rebound force of the telescopic section 401 causes the grinder 6 to move downward or upward. The external force on the dynamic mechanism 2 is then removed or reduced, allowing the dynamic mechanism 2 to re-dock with the static mechanism 3 through internal force, thereby locking the dynamic mechanism 2. Specifically, the following methods can be used.

[0055] See also Figure 3 and Figure 4 The dynamic mechanism 2 includes a resilient member 201 and a rotating end 202 connected to each other, and the resilient member 201 is fixed to the supporting mechanism 1. Specifically, the dynamic mechanism 2 may also include a sleeve 203 and a cross bar 204, and the resilient member 201 may be a spring. The sleeve 203 is laterally fixed on the supporting mechanism 1. The sleeve 203 has a strip-shaped cavity with one end open. One end of the resilient member 201 is fixed to the inner end of the strip cavity, and the other end is connected to the cross bar 204. One end of the cross bar 204 extends out of the opening of the strip cavity and is forked to both sides of the rotating end 202, so that the rotating end 202 can rotate on its own, and the rotation axis of the rotating end 202 is perpendicular to the cross bar 204.

[0056] The compressed resilient member 201 pushes the rotating end head 202 toward the static mechanism 3 to fix it, which may be an engagement fixation, and can constrain the positioning section 402 between the rotating end head 202 and the static mechanism 3 .

[0057] The positioning section 402 is configured to engage with the rotating end 202, and the engagement can be meshing, so that after the rotating end 202 is pushed to the static mechanism 3 and fixed, the positioning section 402 can also be fixed synchronously, and the height of the grinder 6 is also fixed. Therefore, when grabbing the grinder 6, there is no need to resist the contraction force of the telescopic section 401, which is more labor-saving than the method of hanging a single elastic rope directly connected to the grinder 6.

[0058] When the rotating end head 202 leaves the static mechanism 3 , the positioning section 402 can move up and down, thereby driving the rotating end head 202 to rotate, thereby adjusting the height of the grinder 6 .

[0059] See also Figure 5 Specifically, when grinding workpieces, such as metal crafts, if the height of the grinder 6 needs to be adjusted, it is only necessary to pull the grinder 6 sideways so that the positioning section 402 presses the rotating end head 202, thereby making the rotating end head 202 leave the static mechanism 3, and then pull the grinder 6 downward or reduce the pulling force on the grinder 6, so that the grinder 6 can move up and down. After the lateral pulling force is withdrawn, the grinder 6 is fixed, so that the grinder 6 can be adjusted to a suitable grinding height in real time. The operation method is more labor-saving, so that the grinder can maintain a good working state, which is conducive to maintaining the grinding quality and work efficiency.

[0060] The engagement of the positioning section 402 with the rotating end head 202 and the fixation of the rotating end head 202 relative to the static mechanism 3 can be achieved through the following optional structures.

[0061] See also Figure 6 The rotating end 202 includes a middle sprocket 2021, a first left gear 2022, and a first stopper 2023 located on both ends of the middle sprocket 2021. The first left gear 2022 and the middle sprocket 2021 are coaxially fixed. The diameter of the middle sprocket 2021 is smaller than the diameter of the first left gear 2022 and the radial dimension of the first stopper 2023. The positioning section 402 can be a chain that can be engaged with the middle sprocket 2021.

[0062] See also Figure 7 Corresponding to the rotating end 202, the static mechanism 3 includes a central convex member 301 and a second left gear 302 located on one side of the central convex member 301. The second left gear 302 can be directly or indirectly fixed to the support mechanism 1. The central convex member 301 can be fixed to the support mechanism 1 or can rotate relative to the second left gear 302.

[0063] When the rotating end 202 is pushed toward the static mechanism 3: the first left gear 2022 engages with the second left gear 302. Since the first left gear 2022 and the middle sprocket 2021 are coaxially fixed, the middle sprocket 2021 is also fixed synchronously; the middle convex part 301 is inserted between the first left gear 2022 and the first limiting part 2023, and can push the positioning segment 402, so that the positioning segment 402 is always in the position of engaging with the middle sprocket 2021, preventing the positioning segment 402 from slipping out, so the positioning segment 402 is also fixed synchronously, so that the grinder 6 is kept at the required height for convenient grinding.

[0064] In an improved embodiment, the first stopper 2023 is a first right gear of the gear structure. The first left gear 2022 and the first right gear have the same number of teeth and diameter, and are both coaxially fixed to the middle sprocket 2021. In a further preferred embodiment, the first left gear 2022 and the first right gear have the same structure and the same tooth orientation.

[0065] Please continue reading Figure 7 In order to cooperate with the first right gear, the static mechanism 3 further includes a second right gear 303. When the rotating end 202 is pushed toward the static mechanism 3: the first right gear engages with the second right gear 303.

[0066] Specifically, the second right gear 303 is located on the other side of the central protrusion 301 away from the second left gear 302. The second left gear 302 and the second right gear 303 have the same number of teeth and diameter and are coaxially fixed. In a further preferred embodiment, the second left gear 302 and the second right gear 303 have the same structure and teeth in the same orientation, and can mesh with the first left gear 2022 and the first right gear, respectively.

[0067] More preferably, the first left gear 2022, the first right gear, the second left gear 302 and the second right gear 303 have the same structure to improve meshing and rotational stability. The definitions of first, second, left and right are used to assist in explaining the arrangement positions and corresponding relationships of the gears.

[0068] An optional structure for the central convex member 301 is that the central convex member 301 is fixed to the support mechanism 1 via a vertical rod 304. The central convex member 301 has a blocking surface facing the middle sprocket 2021, which can be a vertical plane. When the rotating end 202 is pushed toward the static mechanism 3, the blocking surface blocks or pushes the positioning segment 402, causing the positioning segment 402 to be engaged with the middle sprocket 2021. The blocking surface limits the positioning segment 402. The large contact area of ​​the positioning segment 402, i.e., the large blocking area, provides a greater blocking effect on the positioning segment 402, enhancing the firmness of the positioning segment 402 engaged with the middle sprocket 2021. This allows the positioning segment 402 to rotate in a coordinated manner with the middle sprocket 2021, or be restricted in movement along with the middle sprocket 2021, thereby allowing the height of the grinder 6 to be fixed at a certain position to match the current required grinding height.

[0069] Another alternative configuration for the central protrusion 301 is a disc-shaped protrusion 301 with a thickness slightly smaller than the distance between the first left gear 2022 and the first stopper 2023. The central protrusion 301 is coaxial with the second left gear 302 but can rotate relative to the second left gear 302. The disc-shaped central protrusion 301 also effectively limits the positioning section 402. In particular, the rotatable central protrusion 301 allows it to press against the positioning section 402 in multiple positions. This results in uniform and minimal wear across the central protrusion 301 after prolonged use, extending the service life of the central protrusion 301.

[0070] In the suspension mechanism 4, the telescopic section 401 can be a straight elastic member or a scroll elastic member, or a connected straight elastic member or scroll elastic member. During the grinding process, it can be in a stretched state, thereby tending to pull the positioning section 402 upward and providing a power source for the upward movement of the positioning section 402. When the grinder reaches the highest position, the telescopic section 401 can also be in a naturally stretched state.

[0071] Alternatively, the straight elastic member can be a straight spring or elastic cord. When in tension, the straight spring or elastic cord can provide power for the upward movement of the positioning section 402. Because the rebound direction is similar to the upward movement direction of the grinder 6, the rebound force is large, facilitating quick adjustment of the height of the grinder 6 and providing ease of use.

[0072] Optionally, the connector 403 is an elastic ring structure with a width of 3 to 8 cm. An appropriate width helps secure the grinder 6, improves its stability in mid-air, and reduces its shaking after being released from the hand. If the connector 403 is too narrow, the grinder 6 cannot be stably suspended. If the connector 403 is too wide, it will be difficult to install and manually grasp the grinder 6. When the elastic ring structure is naturally stretched, its diameter is smaller than the diameter of the grinder 6, but it can be placed on the grinder 6 after being stretched.

[0073] See also Figure 4 and Figure 5 , using the above-mentioned grinding machine auxiliary bracket for grinding, the grinding method includes the following:

[0074] The telescopic section 401 can be in a stretched state or a naturally stretched state during the polishing stage.

[0075] The grinder 6 is mounted on the connecting piece 403 , and the height of the grinder 6 is adjusted accordingly according to the position of the workpiece to be grinded. When the current height of the grinder 6 is adapted to the grinding position, the height of the grinder 6 is not adjusted.

[0076] When the height of the current grinder 6 does not match the grinding position, the grinder 6 is pulled sideways so that the positioning section 402 presses the rotating end 202 laterally, and the rebound member 201 is compressed, so that the rotating end 202 leaves the static mechanism 3. The positioning section 402 is pulled downward or the pulling force on the positioning section 402 is reduced, so that the grinder 6 moves downward or upward to the required height, and then the force of pulling the grinder 6 sideways is reduced or cancelled, so that the rotating end 202 moves to the static mechanism 3 and is fixed.

[0077] When the height of the grinder 6 needs to be adjusted, it is only necessary to pull the grinder 6 sideways so that the rotating end 202 leaves the static mechanism 3, and then pull down or reduce the pulling force on the grinder 6. Under the combined action of the manual pulling force and the rebound force of the telescopic section 401, the grinder 6 moves downward or upward, and the rotating end 202 also rotates synchronously. The downward or upward distance can be adjusted in a large range as needed, so that the grinder 6 can be continuously adjusted to a variety of heights. After adjusting the height, cancel or reduce the force of pulling the grinder 6 sideways, so that the rotating end 202 is fixed to the static mechanism 3, and the positioning section 402 is fixed.

[0078] Compared with the method of suspending the grinder 6 with a single elastic rope, which requires manual pulling of the grinder 6 to the required grinding height and continuous application of tension, when using this auxiliary bracket for grinding, it is only necessary to apply tension when the height needs to be adjusted. After the height is adjusted, during the continuous grinding process, there is no need for manual continuous application of tension to counteract the retraction force of the telescopic section 401, making the grinding work more labor-saving and efficient.

[0079] An improved embodiment of the grinding method is that the connecting piece 403 is installed at the center of gravity of the grinder 6, so that the operating force required to be applied to the grinder 6 by the human hand is smaller and more labor-saving. When the grinder 6 is released, the grinder 6 can also be suspended in the air in a relatively balanced manner, thereby improving the safety of use.

[0080] The above are only preferred implementations of the present application. The scope of protection of the present application is not limited to the above embodiments. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications without departing from the principles of the present application should also be considered to fall within the scope of protection of the present application.
