Description

Technical Field

[0001] The utility model belongs to the technical field of grinding-related equipment, and particularly relates to a grinding tool for mechanical manufacturing automation. Background Art

[0002] Grinding is a kind of surface modification technology. Generally, it refers to a processing method that uses a rough object (such as sandpaper containing high-hardness particles) to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness. The grinding device for mechanical manufacturing generally uses a grinding disc to grind the surfaces of various parts.

[0003] In the utility model with the publication number of CN220680240U, a grinding device for mechanical manufacturing is disclosed, which includes a structural plate. A placing mechanism is fixed on the top of the structural plate, and a bracket is fixed at one end of the top of the structural plate. A rotation adjustment mechanism is installed at one end of the bracket. In the utility model, a disc-shaped component is fixed on the top of the placing mechanism, and then according to the size of the disc-shaped component, by rotating the adjustment screw rod, the position of the grinding component is adjusted. The second servo motor drives the connecting shaft and the hexagonal shell to rotate, and then the hexagonal shell drives the grinding rod to rotate at a high speed through the hexagonal block to grind the side of the disc-shaped component. At the same time, the first servo motor drives the rotating shaft to rotate, and the rotating shaft drives the round block and the connecting shell to rotate, thereby driving the grinding component to perform circular motion grinding around the disc-shaped component.

[0004] Although this device is convenient for grinding the circumferential side of circular parts, it also has certain problems. That is, this grinding device needs to completely fix the circular part to its center before it can grind the circumferential side of the circular part. However, the fixing component of this device does not have a good limit alignment function, and it is very difficult to fix it to the exact center for grinding only by personnel judgment. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a grinding tool for mechanical manufacturing automation, which solves the problem that the fixing component in the related solution cannot accurately fix the circular part to the same center of the circle, affecting the grinding of the circumferential side of the circular part.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a grinding tool for mechanical manufacturing automation, which includes a main body component. The main body component further includes an L-shaped fixing piece fixed on the upper surface of the base. A linear module is fixed at one end of the L-shaped fixing piece away from the base. A connecting piece is movably connected to the linear module. A grinding roller is rotatably connected to one end of the connecting piece away from the linear module. A motor one is also fixedly connected to the connecting piece. The power shaft of the motor one penetrates through the connecting piece and is fixedly connected to the grinding roller.

[0008] The fixed component includes a housing fixed to the center of the upper surface of the base. A rack is arranged inside the housing. Support plates and limit rods are respectively fixed at both ends of the rack. Both the support plates and the limit rods penetrate through the side wall of the housing. A fixed rod is vertically rotatably connected to one end of the support plate protruding from the housing. A gear is rotatably connected to the center of the inner cavity of the housing. The gear meshes with the rack. A second motor is fixed to the bottom end of the base. The power shaft of the second motor penetrates through the base and is fixedly connected to the gear.

[0009] A placing disk is rotatably connected to the upper surface of the housing. An activity groove is formed in the placing disk. A clamping bottom plate is arranged in the activity groove. A hydraulic telescopic rod is further fixed to the lower surface of the L-shaped fixing piece. The telescopic end of the hydraulic telescopic rod is rotatably connected to a clamping top plate.

[0010] A third motor is further fixed to the upper surface of the base. A transmission wheel is fixed to the power shaft of the third motor. The same transmission belt is arranged on the outer peripheral side of the transmission wheel and the outer peripheral side of the placing disk.

[0011] Further, three of the rack and the support plates and limit rods connected thereto are provided.

[0012] Further, the three racks are distributed in a circular array centered on the gear, and the three racks are arranged in a staggered manner from top to bottom in sequence.

[0013] Further, support rods are further fixed to the two inner right-angle surfaces of the L-shaped fixing piece.

[0014] Further, the clamping top plate, the placing disk and the center of the gear are on the same vertical axis.

[0015] Further, the first motor and the third motor rotate in opposite directions.

[0016] The utility model has the following beneficial effects:

[0017] Through the arranged fixed component, when in use, a circular part is placed on the clamping bottom plate. The second motor rotates to drive the gear to rotate. The rotation of the gear drives the three racks meshing with it to move, and then drives the fixed rod to move, and finally pushes the circular part to move. Also, since there are three groups of racks hinged to the gear, and they are all arranged in a circular array centered on the gear and are distributed in a staggered manner up and down, the three fixed rods are always on a circle with equal center, so as to adapt to different circular parts and always fix them to the center of the device, solving the problem that in the related solutions, the fixed component cannot accurately fix the circular part to the same center of the circle, which affects the grinding of the peripheral side of the circular part.

[0018] When the position of the circular part is adjusted through the fixed component provided in the present utility model, since the clamping bottom plate is movably arranged in the movable groove, the clamping bottom plate can move arbitrarily within a certain range on the upper surface of the placing plate. This enables the fixing rod to calibrate the circular part and fix it to the center without causing relative movement between the part itself and the clamping bottom plate, preventing scratches on the part itself and solving the problem that scratches are easily generated due to the relative movement between the circular part and the clamping part when adjusting the position of the circular part in the above solution.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0027] Please refer to Figures 1-5As shown in the figure, the utility model relates to a grinding tool for mechanical manufacturing automation, including a main body assembly 1. The main body assembly 1 further includes an L-shaped fixing member 102 fixed on the upper surface of the base 101. One end of the L-shaped fixing member 102 far from the base 101 is fixed with a linear module 103. A connecting member 104 is movably connected to the linear module 103. One end of the connecting member 104 far from the linear module 103 is rotatably connected to a grinding roller 106. A first motor 105 is also fixedly connected to the connecting member 104. The power shaft of the first motor 105 penetrates through the connecting member 104 and is fixedly connected to the grinding roller 106.

[0028] The L-shaped fixing member 102 is mainly used to provide a certain height to adapt to circular parts of different thicknesses to achieve stable fixation from top to bottom. The linear module 103 can mainly adjust the distance between the grinding roller 106 and the fixing assembly 2, so as to adapt to circular parts of different inner diameters.

[0029] The fixing assembly 2 includes a housing 201 fixed at the center of the upper surface of the base 101. A rack 202 is arranged inside the housing 201. A support plate 203 and a limiting rod 204 are respectively fixed at both ends of the rack 202. Both the support plate 203 and the limiting rod 204 penetrate through the side wall of the housing 201. One end of the support plate 203 protruding from the housing 201 is vertically rotatably connected to a fixing rod 205. A gear 206 is rotatably connected to the center of the inner cavity of the housing 201. The gear 206 meshes with the rack 202. A second motor 207 is fixed at the bottom end of the base 101. The power shaft of the second motor 207 penetrates through the base 101 and is fixedly connected to the gear 206.

[0030] The housing 201 is mainly used to protect the internal gear 206 and rack 202 and play a supporting role. The support plate 203 and the limiting rod 204 are mainly used to support the rack 202 so that it can only move back and forth in one direction.

[0031] A placement plate 208 is rotatably connected to the upper surface of the housing 201. An activity groove 2081 is opened in the placement plate 208. A clamping bottom plate 209 is arranged in the activity groove 2081. A hydraulic telescopic rod 213 is also fixed on the lower surface of the L-shaped fixing member 102. The telescopic end of the hydraulic telescopic rod 213 is rotatably connected to a clamping top plate 214.

[0032] A third motor 210 is also fixed on the upper surface of the base 101. A transmission wheel 211 is fixed on the power shaft of the third motor 210. The outer peripheral sides of the transmission wheel 211 and the placement plate 208 are provided with the same transmission belt 212.

[0033] The placement plate 208 mainly plays a driving role. Cooperating with the driving wheel 211, it finally makes the circular part rotate under the drive of the third motor 210 so as to polish it. Among them, the rotation directions of the third motor 210 and the first motor 105 are opposite, which improves the polishing efficiency. At the same time, the clamping bottom plate 209 can move within a certain limit. This makes the circular part not move on the clamping bottom plate 209 when the fixing assembly 2 is aligned and fixed at the center. The clamping bottom plate 209 moves to prevent scratches on the surface of the circular part.

[0034] Furthermore, there are three racks 202 and the supporting plates 203 and limit rods 204 connected to them; three points determine a circle, so three groups of parts are needed to fix the circular part. Less than three groups will not be able to find the rotation and polishing center.

[0035] Furthermore, the three racks 202 are arranged in a circular array centered on the gear 206, and the three racks 202 are arranged in a staggered manner from top to bottom in sequence; the three groups of racks 202 are arranged in a staggered manner so as not to produce motion interference and ensure their normal movement. At the same time, the circular array distribution of the three groups of racks 202 can synchronously adjust the inner diameter to ensure that the circular part is always fixed at the center of the device.

[0036] Furthermore, support rods 1021 are also fixed on the two inner right-angle surfaces of the L-shaped fixing part 102; it forms a triangle to increase its stability.

[0037] Furthermore, the centers of the clamping top plate 214, the placement plate 208 and the gear 206 are on the same vertical axis; only in this way can it be ensured that the circular part is fixed at the center position of the device for circumferential polishing.

[0038] Furthermore, the rotation directions of the first motor 105 and the third motor 210 are opposite, so that the generated rotational forces are opposite, improving the polishing efficiency.

[0039] Working principle: When using this device, place the circular part on the clamping bottom plate 209 on the placement plate 208, and then gently hold it with your hand. Start the second motor 207, so that the three fixing rods 205 move towards the edge of the circular part. Since the clamping bottom plate 209 is movably arranged in the moving groove 2081, the clamping bottom plate 209 can move arbitrarily within a certain range on the upper surface of the placement plate 208. This can make the fixing rods 205 calibrate the circular part so that when it is fixed to the center, the part itself and the clamping bottom plate 209 do not move relative to each other, preventing scratches on the part itself.

[0040] The second motor 207 rotates, driving the gear 206 to rotate. The rotation of the gear 206 drives the three racks 202 meshing with it to move, thereby driving the support plate 203 to move. The support plate 203 drives the fixed rod 205 to move, and finally pushes the circular part to move (it has been explained above that the circular part is relatively stationary with respect to the clamping bottom plate 209. All part movements in the following text are relative movements between the part and the placement plate 208, and the clamping bottom plate 209 and the part are always relatively stationary). At the same time, there are three groups of racks 202 hinged to the gear 206, and they are all arranged in a circular array centered on the gear 206 and are staggered up and down. This enables the three fixed rods 205 to always be on a circle with equal centers, so as to adapt to different circular parts and always fix them to the center of the device, making it convenient to grind their edges.

[0041] After the fixing rod 205 is fixed, the hydraulic telescopic rod 213 is started to tightly clamp through the clamping top plate 214. Then, the grinding roller 106 is brought into contact with the outer peripheral side of the circular part through the linear module 103. Then, the first motor 105 and the third motor 210 are started to start grinding the circumferential side of the circular part. Also, since the rotation directions of the first motor 105 and the third motor 210 are opposite, the efficiency is greatly improved. Finally, it can be taken off after grinding is completed.

[0042] The above are only the preferred embodiments of the present invention and do not limit the present invention. Any modification of the technical solutions recorded in the foregoing embodiments, any equivalent replacement of some technical features, and any modification, equivalent replacement, and improvement made all fall within the protection scope of the present invention.
