Description

Technical Field

[0001] The present application relates to the technical field of workpiece grinding, and in particular to a parts processing center with a grinding function. Background Art

[0002] The lower part of the cylinder block where the crankshaft is installed is called the crankcase. When machining the crankcase, the crankcase needs to be fixed relative to the machine tool by a fixture. During the machining process of the crankcase, a series of machining operations are usually completed on the same equipment.

[0003] A patent with announcement number CN202726476U discloses a composite machine for crankcase processing. The equipment moves the workpiece to the bottom of each power head in sequence through a horizontal moving device, and then performs processing. The equipment can perform operations such as drilling, countersinking and tapping on the crankcase. After processing, the end face of the crankcase usually has burrs, and the crankcase needs to be removed from the positioning tooling, and then the end face of the crankcase is polished to ensure the flatness of the end face of the crankcase, which is more troublesome. Utility Model Content

[0004] The purpose of this application is to address the above-mentioned problems existing in the prior art and to propose a parts processing center with a grinding function.

[0005] The present application can be implemented through the following technical solutions: A parts processing center with grinding function, including a turntable, several processing units, a grinding wheel, a motor 1, an electric push rod and a motor 2. The turntable is detachably mounted with several clamps, the clamps are used to clamp the workpiece, and the several clamps are arranged along the circumference of the turntable; several processing units are arranged around the turntable, and the several processing units can process the workpiece clamped by the clamp; the grinding wheel is located beside the turntable, and the grinding wheel can contact with a workpiece clamped by a clamp; the motor 1 is used to drive the grinding wheel to rotate; the electric push rod is used to drive the grinding wheel to linearly approach or move away from the workpiece clamped by the clamp; the motor 2 is used to drive the turntable to rotate, so that the workpiece clamped by any one of the several clamps can be directly opposite the grinding wheel or a processing unit.

[0006] In the above technical solution, workers can fix the workpiece on the fixture, and the turntable can rotate or stop intermittently. When the turntable stops, the processing unit facing the fixture can process the crankcase end face clamped by the fixture, such as drilling and boring. After several processing units have completed the processing of the crankcase end face in sequence, the turntable rotates to make the crankcase end face face the grinding wheel. At this time, the electric push rod drives the grinding wheel to move linearly close to the crankcase. The grinding wheel itself rotates to grind the crankcase end face to ensure the flatness of the crankcase end face.

[0007] Furthermore, it also includes a brush and a drive assembly. The brush can clean the surface of the grinding wheel; the drive assembly can drive the brush to rotate, the rotation axis of the brush is parallel to the ground, and the rotation axis of the brush and the rotation axis of the grinding wheel are located on different straight lines, so that the bristles of the brush can intermittently face the grinding wheel.

[0008] In the above technical solution, after the grinding wheel has been ground for a period of time, a lot of grinding materials will accumulate on the grinding wheel, thereby affecting the use effect of the grinding wheel. During the rotation of the brush, the bristles of the brush can contact the surface of the grinding wheel to clean the surface of the grinding wheel, thereby preventing the grinding materials from adhering to the surface of the grinding wheel again when the brush cleans the grinding wheel again. The rotation axis of the brush is parallel to the ground. After the brush finishes cleaning the surface of the grinding wheel, the brush can move away from the grinding wheel, thereby preventing the brush from interfering with the horizontal linear movement of the grinding wheel close to the fixture.

[0009] Furthermore, a plurality of water inlet channels are provided at the fixed end of the brush, and the water inlet channels are used for water to pass through, and water can contact the bristles of the brush through the water inlet channels.

[0010] In the above technical solution, after the brush cleans the grinding wheel, some abrasives will be attached to the bristles of the brush. The water inlet channel allows water to enter, and the water can contact the bristles to clean the bristles, so that the abrasives attached to the bristles can leave the brush with the water.

[0011] Furthermore, a sponge is included, and the sponge can absorb water on the bristles of the brush.

[0012] In the above technical solution, water will remain on the surface of the bristles after cleaning. The sponge can absorb the water on the bristles to make the brush dry, thereby reducing the possibility of water on the bristles adhering to the surface of the grinding wheel when the brush contacts the grinding wheel again, thereby ensuring the grinding effect.

[0013] Furthermore, the sponges are configured in a plurality of pieces, and the plurality of sponges are driven to rotate by a motor, so that the bristles of the brush away from the grinding wheel can contact with a sponge among the plurality of pieces.

[0014] In the above technical solution, after the brush frequently contacts the sponge, the water absorption of the sponge will gradually become saturated. At this time, motor three can drive several sponges to rotate so that the sponges that have not absorbed water can face the brush to absorb the water on the bristles. At the same time, the sponges that are close to saturation can be moved away from the brush to facilitate the next step of processing of the sponges that have absorbed water.

[0015] Furthermore, it also includes a fixing block, which can be in contact with the sponge so that water in the sponge can leave the sponge.

[0016] In the above technical solution, the sponge whose water absorption capacity gradually approaches saturation can contact the fixing block, and the fixing block can squeeze the sponge so that the water in the sponge can be squeezed out, so that the sponge can be used again.

[0017] Furthermore, it also includes a collecting tank capable of collecting water in the sponge.

[0018] In the above technical solution, the collecting trough can collect the water flowing out when the sponge is squeezed out, thereby reducing the labor intensity of the workers.

[0019] Furthermore, the collecting tank is connected to the inside of a drain pipe, and the drain pipe is used to drain the water in the collecting tank.

[0020] In the above technical solution, the water collected in the collecting tank can be directly discharged through the drain pipe without manual cleaning of the collecting tank, which is more convenient.

[0021] In summary, the present application has the following technical effects: workers can fix the workpiece on the fixture, and the turntable can intermittently rotate or stop. When the turntable stops, the processing unit directly facing the fixture can process the crankcase end face clamped by the fixture, such as drilling and boring. After several processing units have completed the processing of the crankcase end face in turn, the turntable rotates so that the crankcase end face is directly facing the grinding wheel. At this time, the electric push rod drives the grinding wheel to move linearly close to the crankcase. The grinding wheel itself rotates to grind the crankcase end face to ensure the flatness of the crankcase end face. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Embodiment 1:

[0028] Please refer to the attached drawings in the instruction manual. Figure 1 One embodiment of the present application provides a parts processing center with a grinding function, including a frame 15, the frame 15 is rotatably connected to a turntable 1, the turntable 1 is detachably mounted with six fixtures 2, the fixtures 2 are used to clamp the crankcase, five processing units 3 are placed around the turntable 1, the processing units 3 can be boring machines, drilling machines, etc., the processing units 3 can perform operations such as boring and drilling on the end face of the crankcase, a grinding wheel 4 that can contact the workpiece clamped by the fixture 2 is placed next to the turntable 1, and the grinding wheel 4 and the five processing units 3 surround the turntable 1 are evenly distributed on the circumference and can correspond one to one to the crankcases clamped by the six clamps 2. The turntable 1 is driven to rotate by a motor 2 7. The rotation axis of the turntable 1 is perpendicular to the ground, so that a workpiece clamped by one of the six clamps 2 can be aligned with the grinding wheel 4. The grinding wheel 4 is driven to move linearly in the horizontal direction by an electric push rod 6, so that the grinding wheel 4 can linearly approach or move away from the workpiece clamped by one clamp 2. The grinding wheel 4 is driven to rotate by a motor 5, and the rotation axis of the grinding wheel 4 is parallel to the ground, so that the grinding wheel 4 can grind the workpiece.

[0029] Working principle: Motor 2 7 can drive the turntable 1 to rotate or stop intermittently so that the end face of the crankcase clamped by the fixture 2 can face different processing units 3. During the rotation of the turntable 1, the five processing units 3 can process the end face of the crankcase clamped by the fixture 2 in turn. After the five processing units 3 complete the processing of the crankcase end face, the turntable 1 can drive the crankcase clamped by the fixture 2 to rotate and face the grinding wheel 4. The electric push rod 6 drives the grinding wheel 4 to move linearly close to the fixture 2, so that the grinding wheel 4 can grind the end face of the crankcase to ensure the flatness of the end face of the crankcase.

[0030] Embodiment 2:

[0031] Please refer to the attached drawings in the instruction manual. Figure 2The structure and principle of this embodiment are basically the same as those of the first embodiment, except that a water inlet pipe 16 is placed above the grinding wheel 4, and the shape of the water inlet pipe 16 is approximately right angles. The water inlet pipe 16 includes a horizontal section 161 and a vertical section 162. The horizontal section 161 and the vertical section 162 are arranged perpendicular to each other, and the horizontal section 161 is placed horizontally relative to the ground. The end of the vertical section 162 away from the horizontal section 161 is detachably connected to the fixed end 82 of a brush 8, and the bristles 81 of the brush 8 are installed at the fixed end 82 of the brush 8. The horizontal section 161 is driven to rotate by a driving assembly 9, and the rotation axis of the horizontal section 161 is parallel to the ground, so that the brush 8 can rotate in a vertical plane with the water inlet pipe 16, the rotation axis of the brush 8 is horizontal to the ground, and the rotation axis of the brush 8 and the rotation axis of the grinding wheel 4 are located on different straight lines, so that the bristles 81 of the brush 8 can intermittently face the grinding wheel 4. The driving assembly 9 includes a pulley 91 detachably connected to the axial outer wall of the horizontal section 161, and a pulley 92 located next to the pulley 91. The pulley 91 and the pulley 92 are meshed with the same synchronous belt 93. The pulley 92 is driven to rotate by a motor 94, so that the pulley 92 can drive the water inlet pipe 16 to rotate through the synchronous belt 93 and the pulley 91, thereby rotating the brush 8. After the grinding wheel 4 has been polished for a period of time, a lot of grinding materials will accumulate on the surface of the grinding wheel 4 that is in contact with the workpiece, thereby affecting the use effect of the grinding wheel 4. During the rotation of the brush 8, the bristles 81 of the brush 8 can contact the surface of the grinding wheel 4 to clean the surface of the grinding wheel 4.

[0032] Please refer to the attached drawings in the instruction manual. Figure 2 and Figure 3 The water inlet pipe 16 is used for water supply. The fixed end 82 of the brush 8 is provided with several water inlet channels 821. The fixed end 82 of the brush 8 is connected with the inside of the vertical section 162. The water in the water inlet pipe 16 can contact the bristles 81 of the brush 8 through the water inlet channels 821. After the brush 8 brushes off the grinding material on the grinding wheel 4, a part of the grinding material will remain on the bristles 81 of the brush 8. The water in the water inlet channels 821 can contact the bristles 81 of the brush 8, so that the grinding material attached to the bristles 81 can leave the brush 8 with the water.

[0033] Please refer to the attached drawings in the instruction manual. Figure 2 and Figure 3After the bristles 81 of the brush 8 are cleaned by water, water will remain on the brush 8. When the bristles 81 of the brush 8 come into contact with the surface of the grinding wheel 4 again, the water will adhere to the surface of the grinding wheel 4, thereby affecting the grinding effect of the grinding wheel 4 on the workpiece. A fixing rod 18 is placed beside the brush 8. The fixing rod 18 is placed horizontally. The fixing rod 18 is detachably mounted with three sponges 10. The three sponges 10 are arranged along the axis of the fixing rod 18 itself. One of the three sponges 10 can be facing the brush 8 away from the grinding wheel 4. The sponge 10 can absorb the moisture on the bristles 81 to make the brush 8 dry, so as to reduce the possibility of water on the bristles 81 adhering to the surface of the grinding wheel 4 when the bristles 81 come into contact with the grinding wheel 4 again.

[0034] Please refer to the attached drawings in the instruction manual. Figure 2 and Figure 3 After a period of use, the sponge 10 will become saturated. The fixed rod 18 is driven to rotate by a motor 3 17 so that different sponges 10 can alternately face the brush 8. A fixed block 12 is placed beside the sponge 10, and the fixed block 12 can contact one sponge 10. When a sponge 10 becomes saturated, the motor 3 17 can drive the sponge 10 to rotate a certain angle and leave the brush 8. At the same time, another dry sponge 10 can face the brush 8. During the process of the sponge 10 contacting the fixed block 12, the fixed block 12 can squeeze the sponge 10 and squeeze out the water collected in the sponge 10. A collection tank 13 is placed below the fixed block 12. The collection tank 13 is connected to the inside of a drain pipe 14. The collection tank 13 can simultaneously collect and remove the brush bristles 81 and the water flowing down from the fixed block 12 squeezing the sponge 10. The water in the collection tank 13 can be discharged through the drain pipe 14, which is more convenient.

[0035] Working principle: start the motor 2 7, then the brush 8 can rotate, and during the rotation of the brush 8, it can contact the surface of the grinding wheel 4 to clean the surface of the grinding wheel 4. After the brush 8 leaves the surface of the grinding wheel 4, water can contact the bristles 81 through the water inlet pipe 16 and the water inlet channel 821. The water can clean the bristles 81 in the process of entering the collection tank 13. Then the water inlet pipe 16 stops passing water. During the continued rotation of the brush 8, the bristles 81 can contact a sponge 10, and the sponge 10 can absorb the water in the bristles 81. Then the brush 8 continues to rotate until it is in the initial position.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
