Description

Technical Field

[0001] The invention relates to the technical field of aluminum ingot processing, in particular to an edge trimming and grinding device for aluminum ingot processing. Background Art

[0002] The raw material in our daily industry is called aluminum ingot. Aluminum ingot is widely used. In the processing of aluminum ingot, the role of the trimming and grinding device is to remove burrs and irregular edges on the surface of the aluminum ingot to improve the finish and dimensional accuracy of the product.

[0003] For example, Chinese patent CN216706656U discloses a high-strength recycled aluminum ingot trimming and grinding device. The device is provided with a support block, a screw, a clamping plate, a guide rod and other structures. The screw and the frame are rotated to make a threaded motion, so that the clamping plate moves downward and contacts the aluminum ingot, so that the aluminum ingot is pressed against the support block, so that the aluminum ingot will not move during the processing, and then two grinding discs are tightly fitted to the aluminum ingot by elastic clamping, so that the grinding discs are always in contact with the aluminum ingot during the grinding process, thereby achieving the grinding effect.

[0004] Another example is Chinese patent CN112643346B, which discloses an aluminum ingot trimming and grinding device for metal processing, which can achieve the effects of automatic pushing and trimming of aluminum ingots through the coordination between the placement components, the cutting mechanism and the pushing mechanism.

[0005] However, the above-mentioned devices are mainly used for grinding block-shaped aluminum ingots, such as aluminum ingots in the shape of bars, plate ingots, etc., and since aluminum ingots have different uses, their shapes are also quite diverse. The above-mentioned grinding devices are difficult to stably fix and grind spherical aluminum ingots when processing them. Summary of the invention

[0008] Two adjustment clamps are slidably mounted between the two side plates, and the two adjustment clamps can be adjusted to move closer to or farther from each other;

[0009] A drive shaft is installed through the adjusting clamp and can rotate. The end of the drive shaft is equipped with a clamping part for clamping the ball ingot. The clamping part can adjust the ground axis of the ball ingot and make it coincide with or cross the axis of the drive shaft.

[0010] The grinding part can contact with the welding mark at the equator of the ingot and perform fitting grinding.

[0015] Preferably, laser monitors are provided on opposite surfaces of the two adjusting clamps, the two laser monitors are respectively a transmitter and a receiver, and the two laser monitors are located on the side close to the grinding block, and the laser emitted by the transmitter can be tangent to the equatorial position of the ingot.

[0016] Preferably, an air suction channel is opened inside the second telescopic rod, the air inlet of the air suction channel is connected to the grinding surface of the grinding block, the air outlet of the air suction channel is connected to an external air suction device, and an air pressure sensor is installed in the air suction channel.

[0017] Preferably, a pointer is provided on the outer wall of the adjustment block, and an indicating scale corresponding thereto is provided on the outer wall of the mounting frame.

[0018] Preferably, the opposite surfaces of the two side panels are connected to the adjustment clamping plate via sliders and rails.

The present invention first aligns and grinds the weld mark (also called weld line or water mark, etc.) at the equator of the ingot through the grinding part until it is flush with the other arc surfaces of the ingot, completing the preliminary grinding process, and then adjusts the ingot through the clamping part so that the ground axis and the axis of the driving shaft change from coincidence to intersection, so that the driving shaft drives the ingot to perform an inclined eccentric rotation when rotating, so that the contact grinding range between the ingot and the grinding part can be increased, and the contact position between the equator line and the grinding part of the ingot during the rotation process can be wave-shaped polished, so that the grinding part can perform reciprocating grinding from both sides of the weld mark, thereby achieving the effect of eliminating the connection mark at the weld mark, further eliminating the transition defect between the two semi-arc surfaces of the ingot, and improving the grinding effect of the ingot.

[0023] Second, the present invention can monitor the trimming progress of the trimming knife by setting two laser monitors, thereby avoiding the trimming knife from over-cutting the weld mark and providing preparation for the subsequent fine grinding stage.

[0024] 3. The present invention monitors the air pressure in the air intake channel by means of an air pressure sensor. When it is detected that the air pressure in the air intake channel is lower than a preset value, it means that the grinding block is in full contact with the ingot, i.e. the weld mark is eliminated by grinding. Then the grinding block can be controlled to move away from the ingot, and the grinding process is ended, thereby achieving the purpose of monitoring the grinding progress of the grinding block.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 8 The present invention provides a technical solution: a trimming and grinding device for aluminum ingot processing, comprising a bottom plate 1, side plates 2 are fixed to the tops of both sides of the bottom plate 1, and also includes:

[0036] Two adjusting clamping plates 3 are slidably mounted between the two side plates 2, and the two adjusting clamping plates 3 can be adjusted to move closer to or farther from each other;

[0037] A drive shaft 4 is installed through and rotatably on the adjusting clamp plate 3, and a clamping part for clamping the ball ingot 6 is installed at the end of the drive shaft 4. The clamping part can adjust the ground axis of the ball ingot 6 and make it coincide with or cross the axis of the drive shaft 4;

[0038] The grinding part can contact with the welding mark at the equator of the ingot 6 and grind it closely.

[0039] When the device processes a spherical aluminum ingot, the spherical ingot 6 is placed between two clamping parts, and then the two adjusting clamping plates 3 are controlled by the external structure to approach each other, so that the two clamping parts clamp and fix the spherical ingot 6, and the ground axis of the spherical ingot 6 is first made to coincide with the axis of the driving shaft 4 by the clamping parts, such as Figure 3 and 4 As shown;

[0040] After the ingot 6 is clamped and fixed, the driving shaft 4 is driven to rotate by an external driving mechanism, such as a motor, so that the clamping part and the ingot 6 can be driven to rotate together, and then the grinding part begins to fit and grind the welding mark (also known as welding line or water clamping line, etc.) at the equator of the ingot 6 until it is flush with the rest of the arc surface of the ingot 6, completing the preliminary grinding process;

[0041] It is worth noting that after the initial grinding, there will still be some connection traces between the welding mark and the arc surface of the ingot 6, that is, there will still be transition defects between the two semi-arc surfaces of the ingot 6. Therefore, after the initial grinding, the ingot 6 is adjusted by the clamping part so that the axis of the ground and the axis of the driving shaft 4 change from coincidence to intersection, as shown in FIG. Figure 6 In the state shown, the driving shaft 4 drives the ball ingot 6 to rotate in an inclined eccentric manner when rotating, so that the contact and grinding range between the ball ingot 6 and the grinding part can be increased, that is, Figure 6 The range shown at a in the middle, and the contact position between the equator line and the grinding part of the ingot 6 during the rotation process will be polished in a wave shape, so that the grinding part can perform reciprocating grinding from both sides of the weld mark, thereby achieving the effect of eliminating the connection marks at the weld mark, further eliminating the transition defects between the two semi-arc surfaces of the ingot 6, and improving the grinding effect of the ingot 6.

[0042] After the grinding process is completed, the two adjusting clamps 3 are controlled to move away from each other and the ball ingot 6 is replaced.

[0043] In one of the more preferred embodiments, an implementation of a clamping portion is provided;

[0044] The clamping part includes a mounting frame 5 fixed to the end of the driving shaft 4, an arc groove is provided inside the mounting frame 5 so as to coincide with the center of the ball ingot 6, and an adjusting block 12 is slidably installed in the arc groove, a rotating shaft 13 is rotatably installed through the center of the adjusting block 12, a clamping block 17 is fixed to one end of the rotating shaft 13, a spline hole 14 is provided at the axis center of the driving shaft 4, a spline shaft 15 is slidably installed in the spline hole 14, and the end of the spline shaft 15 opposite to the rotating shaft 13 is rotatably connected via a universal joint 16;

[0045] The clamping portion also includes an adjusting portion for driving the adjusting block 12 to slide and adjust in the arc groove of the mounting frame 5 .

[0046] For details, please refer to Figure 4 and Figure 7When the two adjusting clamps 3 are close to each other, the driving shaft 4, the mounting frame 5 and the structures thereon are driven to approach each other, and the two pole positions of the ball ingot 6 are clamped and fixed by two clamping blocks 17, wherein the surface of the clamping block 17 is provided with an arc surface that can fit the arc surface of the ball ingot 6, so as to facilitate stable clamping and fixing thereof, and the larger the contact surface between the clamping block 17 and the ball ingot 6, the higher the stability during the clamping process;

[0047] In the above-mentioned preliminary grinding stage, the adjustment block 12 is located in the middle of the arc groove of the mounting frame 5, that is, Figure 3 In the state shown, the drive shaft 4, the spline shaft 15, the universal joint 16 and the rotating shaft 13 are all in the same axis state, so when the drive shaft 4 rotates, it will directly drive the internal structure to rotate together through the mounting frame 5, thereby driving the ball ingot 6 to rotate coaxially to complete the initial grinding stage;

[0048] In the subsequent grinding stage, the adjustment unit adjusts the position of the adjustment block 12 in the arc groove of the mounting frame 5, so that the ball ingot 6 can change its angle with its center as the center point, which will not affect the rotation of the ball ingot 6. At the same time, the ground axis of the ball ingot 6 will also be at an angle with the drive shaft 4. Figure 6 As shown, to complete the subsequent further polishing stage;

[0049] It is worth mentioning that after the position of the adjusting block 12 is adjusted, the spline shaft 15 is still in a transmission state with the rotating shaft 13 under the connection of the universal joint 16. In this way, when the ball ingot 6 rotates with the mounting frame 5, the spline shaft 15 can also drive the rotating shaft 13 to rotate through the universal joint 16, so that the ball ingot 6 can also rotate along its axis. Figure 6 As shown by the rotating arrow in the figure, this can further increase the range of contact between the welding mark on the ingot 6 and the grinding part, thereby improving the effect of subsequent fine grinding, and providing a more favorable way to further eliminate the transition marks between the two semi-arc surfaces of the ingot 6.

[0050] In one of the more preferred embodiments, an implementation of an adjustment portion is provided;

[0051] The adjusting part includes a worm gear 18 fixed on the inner arc surface of the mounting frame 5. An inner groove is provided in the adjusting block 12 near the worm gear 18. A worm 19 meshing with the worm gear 18 is rotatably installed in the inner groove. A rotating handle is installed at one end of the worm 19.

[0052] For details, please refer to Figure 8When the control adjustment block 12 is adjusted, the worm 19 is rotated by turning the handle, and the adjustment block 12 can be moved and adjusted along the arc groove in the mounting frame 5 by utilizing the meshing cooperation between the worm 19 and the worm gear teeth 18. The rotation directions of the worms 19 of the two adjustment parts are opposite, so that the ball ingot 6 can be rotated and adjusted with its center as the center.

[0053] In one of the more preferred embodiments, an implementation of a grinding portion is provided;

[0054] The grinding part includes a first telescopic rod 7 which is slidably installed in one side panel 2, and a detachable and replaceable trimming knife 8 is installed at one end of the first telescopic rod 7 close to the ball ingot 6. It also includes a second telescopic rod 9 which is slidably installed in the other side panel 2, and a grinding block 10 is fixed at one end of the second telescopic rod 9 close to the ball ingot 6, and the outer wall of the grinding block 10 is provided with the same arc surface as the ball ingot 6. The first telescopic rod 7 and the second telescopic rod 9 are both driven by a telescopic cylinder installed on the side panel 2.

[0055] For details, please refer to Figure 1 and Figure 2 Since the weld mark may protrude a part of the flake, in the preliminary grinding stage, the first telescopic rod 7 will be controlled to extend through the telescopic cylinder, and the trimming knife 8 on it will contact the weld mark, so as to perform preliminary shortening work on the weld mark, so that most of the protruding flakes are cut off, and the trimming knife 8 and the weld mark are perpendicular to each other. By setting the edge of the trimming knife 8 to an arc shape, the weld mark can be trimmed closer to the arc surface of the ingot 6, so as to provide preparation for subsequent fine grinding;

[0056] In the fine grinding stage, the first telescopic rod 7 is controlled to move away and the second telescopic rod 9 is controlled to move closer by the telescopic cylinder so that the grinding block 10 contacts with the remaining weld mark and grinds it. In this process, since the state of the ball ingot 6 has been switched, as the grinding block 10 grinds the weld mark, the remaining arc surface of the grinding block 10 will gradually contact with the two semi-arc surfaces of the ball ingot 6, thus completing the fine grinding stage and eliminating the transition marks between the two semi-arc surfaces.

[0057] In one of the more preferred embodiments, an implementation method capable of detecting the trimming progress of the trimming knife 8 is provided;

[0058] Laser monitors 11 are provided on opposite sides of the two adjustment clamps 3 . The two laser monitors 11 are respectively a transmitter and a receiver. The two laser monitors 11 are located on one side close to the grinding block 10 , and the laser emitted by the transmitter can be tangent to the equatorial position of the ingot 6 .

[0059] For details, please refer to Figure 3As the trimming knife 8 cuts the weld mark, its diameter will gradually decrease, so its obstruction to the laser emitted by the transmitter will gradually decrease. When the receiver can receive the laser emitted by the transmitter, it means that the trimming knife 8 has cut off the excess part of the weld mark, and the trimming knife 8 can be withdrawn and replaced with the grinding block 10 for the subsequent fine grinding stage.

[0060] In one of the more preferred embodiments, an implementation method capable of detecting the grinding progress of the grinding block 10 is provided;

[0061] An air suction channel 20 is provided inside the second telescopic rod 9 , an air inlet of the air suction channel 20 is connected to the polishing surface of the polishing block 10 , an air outlet of the air suction channel 20 is connected to an external air suction device, and an air pressure sensor is installed in the air suction channel 20 .

[0062] For details, please refer to Figure 3 and Figure 5 During the grinding process of the grinding block 10, air is sucked into the suction channel 20 through an external suction device, so that the debris powder generated by grinding can be sucked in the early stage of fine grinding. At the same time, due to the weld mark, the grinding block 10 and the arc surface of the ingot 6 cannot be completely fitted together, so the air pressure in the suction channel 20 will not change too much. As the weld mark is polished away, the arc surface of the grinding block 10 will contact the arc surface of the ingot 6. At this time, the grinding surface of the grinding block 10 is equivalent to being closed by the arc surface of the ingot 6, so the air pressure in the suction channel 20 will decrease sharply. When the air pressure sensor detects that the air pressure of the suction channel 20 is lower than the preset value, it can be explained that the grinding block 10 is in full contact with the ingot 6, that is, the weld mark is polished away, and then the grinding block 10 can be controlled to move away from the ingot 6, and the grinding process is ended.

[0063] In one of the more preferred embodiments, a pointer is provided on the outer wall of the adjustment block 12, and an indicating scale corresponding thereto is provided on the outer wall of the mounting frame 5.

[0064] The pointer and the indicating scale can be used to adjust the adjustment angle of the adjustment block 12, and also provide a reference and comparison for the adjustment on both sides to ensure that the adjustment angles on both sides are the same, so as to avoid affecting the rotation of the ingot 6. In addition, the required angle can also be adjusted according to the width of the weld mark, which can be determined according to the specific situation.

[0065] In one of the more preferred embodiments, the opposite surfaces of the two side panels 2 and the adjustment clamping plate 3 are connected via sliders and rails.

[0066] In one of the more preferred embodiments, a chute 21 for receiving waste is further provided on the top of the base plate 1, and cooling liquid is also contained in the chute 21. The chute 21 can collect the debris generated by grinding, and the presence of cooling liquid can prevent the debris from being raised again. Moreover, if the ingot 6 that has just been ground may have a high temperature, it can also be directly dropped into the chute 21 during disassembly and cooled by the cooling liquid.

[0067] In one of the more preferred embodiments, a spray head is further included above the ingot 6 for spraying coolant on the ingot 6. During the grinding process, the grinding area can be cooled by spraying coolant with the spray head, and the grinding block 10 can also be cooled.

[0068] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
