Description

Technical Field

[0001] The present invention relates to the technical field of submersible pump processing, and more specifically, to an automatic grinding machine for submersible pump processing. Background Art

[0002] The submersible pump casing is made of metal materials through processes such as welding, grinding, cleaning and spraying. When the existing technology grinds the submersible pump casing, the submersible pump casing is first fixed on a lathe, and the lathe is used to drive the submersible pump casing to rotate slowly. Then, the electric drive component drives the high-speed rotating grinding wheel to move horizontally along the surface of the submersible pump casing, so as to fully grind the surface of the submersible pump casing. In order to improve the grinding efficiency, the existing equipment will install two identical grinding wheels on the same electric drive component, and then drive the two identical grinding wheels to move horizontally along the surface of the submersible pump casing through the driving component. The surface of the submersible pump casing is grinded by the two grinding wheels at the same time. However, when fine grinding is performed later, the grinding wheel needs to be manually disassembled and replaced, and the operation process is cumbersome and inefficient.

[0003] Before the grinding wheel is completely scrapped, maintenance personnel will regularly control the grinding wheel to separate the grinding debris remaining inside the grinding wire due to grinding from the grinding wheel by self-rotation and centrifugal swing. However, under normal conditions, the grinding wire of the grinding wheel is not fully unfolded, and the debris remaining on the grinding wire is easily entangled and blocked by other surrounding grinding wires or debris, resulting in poor centrifugal swing separation effect, and manual additional processing is required, which also prolongs the entire grinding work cycle and reduces processing efficiency.

[0032] The cleaning assembly includes round rods 2013 and round balls 2014; twenty round rods 2013 are welded on the cover 10; four round balls 2014 are inserted on each round rod 2013, and the wire brushes on the grinding wheel 1 8 and the grinding wheel 2 9 are moved by the round balls 2014.

[0033] Grinding wheel one 8 is set as a fine grinding wheel; grinding wheel two 9 is set as a coarse grinding wheel.

[0034] The working principle of the above embodiment is as follows:

[0035] First, the telescopic cylinder 2011 is used to apply a rightward thrust to the T-shaped block 2010, and the T-shaped block 2010 applies a rightward thrust to the fixing rod 2012, so that the fixing rod 2012 clamps the pump casing 11 on the fixture 208, and the chuck head 207 is started. The chuck head 207 drives the fixture 208 to rotate, so that the groove portion 92 of the fixture 208 applies a thrust to the branch pipe portion 91 of the pump casing 11, thereby driving the pump casing 11 to rotate slowly, and the pump casing 11 drives the fixing rod 2012 to rotate through the friction force. At the same time, the motor 203 is started, and the motor 203 drives the gear 1 204 to rotate, and the gear 1 204 drives the gear 2 205 and the gear 3 206 to rotate, and the gear 2 205 drives the grinding wheel 1 8 to rotate, and the gear 1 204 drives the gear 2 205 and the gear 3 206 to rotate. Wheel three 206 drives grinding wheel two 9 to rotate, starts electric slide rail 201 and electric slider 202, electric slider 202 drives DD motor one 3 and parts thereon to move leftward, thereby drives grinding wheel one 8 and grinding wheel two 9 to move leftward, makes the front side of grinding wheel one 8 and grinding wheel two 9 contact the rear side of pump casing 11, and moves straight to the left along the rear side of pump casing 11, thereby grinding the outer annular surface of pump casing 11 by grinding wheel one 8 and grinding wheel two 9, in this process, grinding wheel two 9 always contacts pump casing 11 before grinding wheel one 8, that is, electric slider 202 only needs to move leftward once, so that grinding wheel two 9 and grinding wheel one 8 can perform one rough grinding and one fine grinding on pump casing 11 successively, which is highly efficient.

[0036] When the grinding wheel 18 moves to the left and away from the left end of the outer ring surface of the pump housing 11, it is ready to start grinding the arc surface of the left end of the pump housing 11. The DD motor 13 drives the connecting block 14 and the parts thereon to rotate, thereby adjusting the inclination angle of the grinding wheel 29 so that the grinding wheel 29 is always facing the arc surface of the left end of the pump housing 11. At the same time, the telescopic cylinder 15 drives the DD motor 26 and the parts thereon to move back and forth so that the grinding wheel 29 is always in contact with the arc surface of the left end of the pump housing 11. At the same time, the electric slider 202 drives the DD motor 3 and the parts thereon to move water The DD motor 26 and the parts thereon are moved backwards, so that the grinding wheel 29 is always facing the arc surface of the left end of the pump housing 11 and moves to the left, thereby fully performing a rough grinding operation on the arc surface of the left end of the pump housing 11. Then, the telescopic cylinder 15 drives the DD motor 26 and the parts thereon to move backwards, so that the grinding wheel 29 is away from the arc surface of the left end of the pump housing 11. Then, the DD motor 26 is started, and the DD motor 26 drives the DD motor 26 and the parts thereon to rotate 180 degrees, so that the positions of the grinding wheels 18 and the grinding wheels 29 are swapped, and then the above operation is repeated to perform a fine grinding operation on the arc surface of the left end of the pump housing 11 through the grinding wheel 18. During the grinding operation, the rough grinding and the fine grinding are performed sequentially. Regardless of whether the rough grinding or the fine grinding is performed, the telescopic cylinder 15 and the electric slider 202 are responsible for making the grinding wheel 29 or the grinding wheel 18, whichever is working, move in an arc shape along the arc surface at the left end of the pump housing 11, and the DD motor 13 is responsible for continuously rotating and adjusting the relative position between the grinding wheel 29 and the grinding wheel 18 during the process. When grinding the arc surface at the left end of the pump housing 11, it should be rotated counterclockwise from a top-down perspective, so that the diameter direction of the wheel body that needs to work within a period of time is always Towards the center of the arc surface at the left end of the pump casing 11, and the other wheel body that does not need to work is always located at the right rear of the working wheel body. As long as the wheel body radius is reduced within a reasonable range and the distance between the two wheel bodies is increased, it can be ensured that the wheel body that does not need to work is within the adjustment rotation range of the DD motor 3 and does not touch the surface of the pump casing 11 at all. Moreover, because the wheel body that does not need to work is located at the right rear of the working wheel body, it will not contact and interfere with the fixing rod 2012 located on the left side of the working wheel body. During the above process, the pump casing 11 rotates continuously in one direction and is polished to the entire surface.

[0037] Then, the grinding wheel 1 8 and the grinding wheel 2 9 are controlled to move backward by the telescopic cylinder 1 5, and then the grinding wheel 2 9 is controlled to move rightward by the electric slider 202. During the rightward movement, the grinding wheel 1 8 and the grinding wheel 2 9 are in a state of not contacting the pump casing 11 after the backward movement, so that the grinding wheel 2 9 moves to the right end of the outer annular surface of the pump casing 11. At this time, in order to avoid the branch pipe portion 91, the pump casing 11 is controlled to reciprocate by the chuck head 207, and then the above operation is repeated, and the position other than the arc branch pipe portion 91 at the right end of the pump casing 11 is roughly ground by the grinding wheel 2 9, and then the DD motor 2 6 swaps the positions of the grinding wheel 1 8 and the grinding wheel 2 9 so that the grinding wheel 1 8 is located on the right side of the hollow block 7, and then the grinding wheel 1 8 is used to perform fine grinding on the position other than the arc branch pipe portion 91 at the right end of the pump casing 11. During this process , the telescopic cylinder 15 and the electric slider 202 are also required to make the working one of the grinding wheel 29 or the grinding wheel 8 move in an arc shape along the arc surface at the right end of the pump casing 11. It is also necessary to first adjust the non-working wheel body to the left rear of the working wheel body through the DD motor 3. In a top-down perspective, the DD motor 3 needs to rotate clockwise. Therefore, the non-working wheel body does not touch the surface of the pump casing 11, nor does it interfere with the fixture 208 on the right side of the working wheel body, thereby avoiding the problem that the grinding wheel 8 cannot perform fine grinding on the arc surface at the end of the pump casing 11 due to the interference between the grinding wheel 29 and the lathe assembly. After grinding, the grinding wheel 18 and the grinding wheel 29 have moved back to the initial state after two position exchanges, and the next grinding operation can be started immediately without the need for further position adjustment.

[0038] The grinding wheels 18 and 29 are used to grind the pump casing 11, and some of the debris generated by the grinding wheels 18 and 29 will be thrown into the casing 10. At the same time, some of the debris will be stuck in the wire brushes of the grinding wheels 18 and 29, causing the high-speed rotating grinding wheels 18 and 29 to throw the debris onto the surface of the pump casing 11 during the subsequent grinding of other pump casings 11, thereby scratching the surface of the pump casing 11. Therefore, before the DD motor 26 drives the hollow block 7 to rotate, the telescopic cylinder 15 drives the DD motor 26 and the parts thereon to move backward and retract into the casing 10, so that the axis of the grinding wheels 18 and 29 and the top projection of the overall center of all the round rods 2013 are on the same straight line, and then the DD motor 26 controls the grinding wheels 18 and 29 to perform circular motion, and the positions of the grinding wheels 18 and 29 are swapped. In this process, Figure 6As shown, when the grinding wheel 1 8 and the grinding wheel 2 9 perform circular motion with the axis of the DD motor 2 6, the wire brushes on the grinding wheel 1 8 and the grinding wheel 2 9 contact the ball 2014 and are subjected to the blocking force in the axial direction, thereby the wire brushes are pushed apart in the axial direction; when the grinding wheel 1 8 and the grinding wheel 2 9 rotate, the wire brushes on the grinding wheel 1 8 and the grinding wheel 2 9 contact the ball 2014 and are subjected to the blocking force in the radial direction, thereby the wire brushes are pushed apart in the radial direction, thereby fully pushing apart the wire brushes on the grinding wheel 1 8 and the grinding wheel 2 9, and the steel wire after rotating away from the ball 2014 does not return to the steel wire group in a short time, does not contact with other steel wires, and is in a relatively independent state. At this time, there is almost no obstacle to the debris on these steel wires from other steel wires, so it is easy to remove the debris remaining on these steel wires. The debris inside the wire brush is thrown out, and it is not easy to have the problem that although a certain centrifugal force is applied, the debris on the wire is blocked by the surrounding wires or the debris on the surrounding wires blocks each other, resulting in poor centrifugal separation effect. In addition, the separation area is inside the cover 10, and it is not easy to be thrown onto the surface of the pump casing 11 that has just been polished. That is, when the grinding wheels 1 8 and 2 9 are controlled by the DD motor 2 6 to perform the position swap operation, the round rod 2013 and the round ball 2014 can also be used to throw out the debris remaining in the wire brush to avoid the debris being thrown onto the surface of the pump casing 11 and scratching it during the subsequent polishing process; after most of the surface of the pump casing 11 is polished by the grinding wheels 1 8 and 2 9, the clamping positions at both ends of the pump casing 11 are manually polished. Such differentiated polishing can improve the overall polishing efficiency.

[0039] According to the above working principle, we know that the present invention has the following effects:

[0040] The positions of grinding wheel 1 8 and grinding wheel 2 9 are swapped by DD motor 2 6, and then the left end curved surface of the pump casing 11 is finely polished by grinding wheel 1 8. During this process, grinding wheel 2 9 is always located on one side of the center of the pump casing 11, that is, grinding wheel 2 9 will not interfere with the jig 208 and the fixing rod 2012 located at both ends of the pump casing 11, thereby avoiding the problem that grinding wheel 1 8 cannot perform fine polishing operation on the curved surface at the end of the pump casing 11 due to interference between grinding wheel 2 9 and the lathe assembly. At the same time, when grinding wheel 1 8 and grinding wheel 2 9 are controlled by DD motor 2 6 to perform the position swap operation, the round rod 2013 and the round ball 2014 can also be used to throw out the debris remaining in the wire brush to avoid the debris being thrown onto the surface of the pump casing 11 and scratching it during the subsequent grinding process.

[0041] Example 2

[0042] On the basis of Example 1, Figure 4-Figure 6 As shown, the connecting block 14 is detachably connected to the cover 10. The cover 10 is narrow at both ends and wide in the middle.

[0043] The outer side of the housing 10 is provided with convex strips.

[0044] The machine tool 1 is provided with heat dissipation holes for heat dissipation.

[0045] The working principle of the above embodiment is as follows:

[0046] During regular cleaning, the worker puts his fingers on the convex strip of the cover shell 10, then unscrews the cover shell 10, and then manually takes out the cover shell 10. During this process, if the movement trajectory of the cover shell 10 is not controlled well by the human, the impurities in the cover shell 10 may come into contact with the grinding wheel 1 8 and the grinding wheel 2 9, thereby sweeping the impurities onto the machine tool 1, which is not conducive to collection. Therefore, before taking out, the planar parts of the grinding wheel 1 8 and the grinding wheel 2 9 can be controlled by the DD motor 2 6 to be parallel to the horizontal plane, so that the impurities at the bottom of the cover shell 10 are further away from the grinding wheel 1 8 and the grinding wheel 2 9, and the middle section area of ​​the cover shell 10 is wider, and the surface in the middle section area of ​​10 itself will not contact the grinding wheel 1 8 and the grinding wheel 2 9, and the debris falling on the two ends of the interior will gather to the middle, so that when the cover shell 10 is pulled forward manually, the impurities inside it will not come into contact with the wire brushes of the grinding wheel 1 8 and the grinding wheel 2 9, thereby preventing the wire brushes from brushing out the impurities.

[0047] According to the above working principle, we know that the present invention has the following effects:

[0048] The DD motor 2 6 controls the grinding wheel 1 8 and the grinding wheel 2 9 to be further away from the impurities at the bottom of the cover 10, so that when the cover 10 is manually pulled forward, the impurities inside will not contact the wire brushes of the grinding wheel 1 8 and the grinding wheel 2 9, thereby preventing the wire brushes from brushing out the impurities.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
