Description

Technical Field

[0001] The invention belongs to the technical field of laser polishing equipment, and in particular relates to a laser polishing equipment and a polishing method thereof. Background Art

[0002] Laser polishing equipment is an advanced beam processing equipment. It uses a high-energy laser beam to irradiate the surface of the material, causing the surface to melt and diffuse rapidly, thereby achieving polishing. The working principle of laser polishing equipment is to use a high-energy laser beam to irradiate the surface of the workpiece, causing the surface to melt and vaporize rapidly, and to control the irradiation area and intensity of the laser beam through an optical lens to achieve the desired processing effect. During the processing, the energy of the laser beam is highly concentrated, and stains, burrs, scratches, etc. on the surface of the workpiece can be removed in a very short time without causing major damage to the workpiece.

[0003] Conventional laser polishing equipment is mainly composed of a laser polishing machine and a workpiece fixing device, wherein the workpiece fixing device can clamp the workpiece by two relatively close clamping blocks. After the workpiece is clamped, the laser polishing machine is displaced to achieve the polishing operation on the workpiece surface. In the prior art, a screw rod and a slide table are generally used to fix the workpiece. Although this workpiece fixing method can prevent the workpiece from displacement during polishing, the overall fixing process is relatively complicated, and it is impossible to automatically tighten the workpiece after the workpiece is placed. The tightening efficiency needs to be improved.

[0004] At the same time, when polishing the workpiece, especially when polishing a cylindrical workpiece, since the current polishing equipment cannot move or rotate the workpiece after fixing it, the polishing equipment needs to rotate the workpiece to polish other positions of the workpiece after polishing the top of the workpiece. When rotating, it is necessary to first release the clamp and rotate the workpiece before clamping it again. The whole process is relatively complicated, which seriously affects the polishing efficiency of the polishing equipment. Summary of the invention

[0005] The object of the present invention is to provide a laser polishing device and a polishing method thereof to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a laser polishing device, comprising a base, support legs are installed at the four corners of the bottom end of the base, a frame is movably installed on the top of the base, the frame is displaced left and right relative to the base, a laser polishing machine is movably installed on the top of the inner side of the frame, the laser polishing machine is displaced front and back relative to the frame, a card slot is provided on the front and back sides of the inner cavity of the base, a locking component is movably connected between the two card slots, the locking component is displaced left and right relative to the card slot, an adjustment component is provided at the bottom end of the base, and a through hole is provided at the bottom end of the base. The top of the adjusting component is connected to the bottom of the two locking components, the middle of the top of the adjusting component is fixedly connected with an extension rod, the top of the extension rod passes through the top of the base and is fixedly connected with a bottom plate, the front and rear sides of the top of the bottom plate are provided with through grooves and a power component is movably installed inside the through grooves, the middle of the bottom end of the adjusting component is fixedly connected with an extension frame, the bottom end of the extension frame is fixedly connected with a three-way valve, the bottom end of the three-way valve is connected to an external air pump, and the left and right sides of the three-way valve are connected with two power components.

[0007] When polishing a workpiece, the frame can be moved to one side so that the frame is located on one side of the base, and the bottom end of the three-way valve is connected to the external air pump, and the parts to be polished are prepared to complete the preparation before polishing;

[0008] When clamping the workpiece, the workpiece can be inserted into the base in parallel, that is, the two ends of the workpiece correspond to the two locking components.

[0009] As a further technical solution of the present invention, the locking assembly includes a locking block, and the front and rear sides of the locking block near the top are fixedly connected with a clamping block. The locking block is movably clamped between the clamping block and the clamping slot. The locking block is displaced left and right relative to the clamping slot. A guide slope is provided at the relatively close ends of the two locking blocks, and a reset spring located inside the clamping slot is fixedly connected between the two clamping blocks.

[0010] As a further technical solution of the present invention, an adjustment groove is opened in the middle of the locking block, and an adjustment block is movably connected inside the adjustment groove. The adjustment block moves up and down relative to the adjustment groove, and a thimble is installed at one end of the two adjustment blocks that are relatively close to each other.

[0011] As a further technical solution of the present invention, an electric push rod is vertically installed at one end of the two locking blocks that are relatively far away, the output end of the adjustment slot is connected to the top of the adjustment block, and the middle part of the bottom end of the locking block is connected to the adjustment component.

[0012] When the two ends of the workpiece are in contact with the guiding inclined surface, the two locking blocks move away from each other under the guiding action of the guiding inclined surface, that is, the two locking blocks are displaced relative to the card slot through the card block, and the return spring inside the card slot is stretched, and the workpiece continues to move downward until the two ends of the workpiece are in contact with the two ejector pins, and the bottom end of the workpiece can be in contact with the two power components;

[0013] And according to the diameter of the workpiece, the electric push rod can be turned on to control the up and down displacement of the adjustment block relative to the adjustment slot. At this time, the ejector pin can be driven up and down synchronously until the left and right ejector pins are in contact with the middle of the left and right ends of the workpiece, and the corresponding adjustment process can be completed.

[0014] As a further technical solution of the present invention, the adjustment assembly includes a movable plate located in the middle of the bottom end of the base, and a first fixed seat is installed on the left and right sides of the top of the movable plate, and the end of the first fixed seat away from the movable plate is movably connected to a connecting rod through a rotating shaft, and the end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat through a rotating shaft.

[0015] As a further technical solution of the present invention, the middle part of the top end of the movable plate is connected to the bottom end of the extension rod, the middle part of the bottom end of the movable plate is connected to the top end of the extension frame, and the top end of the second fixed seat is fixedly connected with a mounting block, and the top end of the mounting block passes through the top end of the through slot and is connected to the bottom end of the locking block.

[0016] When the workpiece is inserted into the device in parallel, the bottom end of the workpiece can exert a downward force on the two power components. At this time, the bottom plate is displaced downward by the force, and drives the extension rod to move downward, which can drive the movable plate to move downward. At this time, the two connecting rods are deflected, that is, the angle between the two connecting rods and the movable plate is reduced, and the two mounting blocks are driven relatively close, and finally the two locking blocks are pulled relatively close. At this time, the two ends of the workpiece can be clamped by the two locking blocks, so that the bottom end of the workpiece contacts the power component, and the two ends of the workpiece contact the two ejector pins, completing the clamping process of the workpiece.

[0017] By utilizing the downward pressing force when clamping the workpiece, the bottom plate can be moved downward simply by pressing the workpiece downward, and the two locking components are driven close to each other through the action of the adjusting component, so that the workpiece is automatically clamped at the position between the two locking components. The entire clamping process only requires the workpiece to be loaded into the interior of the device as required to complete the automatic clamping, without the need for complicated operations, significantly shortening the tightening time and improving the tightening efficiency.

[0018] As a further technical solution of the present invention, the power assembly includes a power tank, and two of the power tanks are symmetrically installed on the front and rear sides of the bottom end of the movable plate through a machine base. The bottom ends of the two power tanks are connected to the left and right sides of the three-way valve, and the top ends of the power tanks are fixedly connected to a cooling pipe located below the through groove.

[0019] During the polishing process of the workpiece, cold air can be input into the interior of the three-way valve by turning on the external air pump, and enter the interior of the two power components after being distributed at both ends of the three-way valve. At this time, the cold air can enter through the bottom end of the power tank and be discharged through the top end of the power tank, that is, discharged through the cooling pipe. At this time, the discharged cold air can directly act on the bottom end position of the outer side of the workpiece to quickly cool the surface of the workpiece and complete the cooling process.

[0020] By utilizing the input of external cold air, the cold air is guided into the interior of the power component, and the cold air is output from bottom to top to the surface of the workpiece through the cooling pipe, so that the surface of the workpiece is quickly cooled. At the same time, the rotation of the workpiece can achieve rapid cooling of the outer side of the workpiece. At the same time, since the cooling position does not correspond to the polishing position, it will not affect the polishing, thereby improving the polishing quality.

[0021] As a further technical solution of the present invention, a first transmission shaft is movably connected to the middle part of the power tank, and an impeller located inside the power tank is fixedly sleeved on the outer side surface of the first transmission shaft. The power assembly also includes a guide wheel located inside the through groove of the bottom plate, and mounting frames are provided on the left and right sides of the bottom end of the outer side surface of the guide wheel. The top end of the mounting frame is connected to the bottom end of the bottom plate, and a second transmission shaft is fixedly sleeved on the middle part of the guide wheel.

[0022] As a further technical solution of the present invention, the second transmission shaft passes through one side of the mounting frame and is movably connected to the two mounting frames, and a synchronous belt is movably sleeved on both sides of the left and right sides of the second transmission shaft, and the other end of the synchronous belt is movably sleeved on the left and right sides of the outer side surface of the first transmission shaft, and the first transmission shaft is transmission-connected to the second transmission shaft through the synchronous belt.

[0023] And when cold air enters the interior of the power tank, the flowing cold air can drive the impeller to rotate. When the impeller rotates, it can drive the first transmission shaft to rotate rapidly, and at the same time drive the second transmission shaft to rotate through the synchronous belt. When the second transmission shaft rotates, the guide wheel located on the outer side of the second transmission shaft rotates accordingly. Since the outer side of the guide wheel is in contact with the outer side of the workpiece, when the guide wheel rotates, the workpiece can be driven to rotate by relying on the friction force, thereby assisting in completing the polishing process of the workpiece.

[0024] By using cooling gas in the process of polishing the workpiece and coordinating the contact between the guide wheel and the bottom end of the workpiece when the workpiece is clamped, and converting the flowing air into the power for the rotation of the guide wheel, the workpiece can be quickly rotated in the clamped state and its polishing position can be changed, avoiding the problem of traditional devices requiring the workpiece to be disassembled, rotated and fixed again, thus simplifying the entire operation process and improving the overall polishing efficiency.

[0025] A polishing method for a laser polishing device comprises the following steps:

[0026] S1: When polishing a workpiece, the frame can be moved to one side of the base by moving the frame first. At this time, the two ends of the workpiece can be aligned with the two locking components and the workpiece can be inserted in parallel. At this time, the two ends of the workpiece can contact between the guide bevels, and the two locking blocks are relatively separated by the guiding effect of the guide bevels. Under the action of the reset spring, the two locking blocks are brought close to each other, so that the two ends of the workpiece are fixed at the position between the two ejector pins.

[0027] S2: At this time, the bottom end of the workpiece can contact the outer side of the guide wheel. At this time, the electric push rod can be turned on to adjust the upper and lower positions of the adjustment block so that the ejector pin contacts the middle of the end face of the workpiece. At the same time, when the workpiece is clamped, the bottom plate and the extension rod move downward, and drive the movable plate to move downward, and at the same time drive the two mounting blocks to move relatively close, and assist the two locking blocks to move relatively close, completing the clamping process of the workpiece;

[0028] S3: After the workpiece is clamped, the laser polisher can be turned on, and the left and right displacement of the frame and the front and back displacement of the laser polisher can be controlled to polish different positions of the workpiece. At the same time, during the polishing process, the external air pump can be turned on to input cold air into the inside of the three-way valve, and enter the inside of the power tank through the three-way valve, and be discharged through the cooling pipe to act on the bottom end of the workpiece, completing the cooling process of the workpiece during polishing;

[0029] S4: When cold air enters the power tank, it can drive the impeller to rotate. At this time, the first transmission shaft rotates accordingly, and drives the second transmission shaft to rotate through the synchronous belt. At this time, the guide wheel at the top rotates accordingly. At this time, the bottom end of the workpiece is then subjected to the guiding force, which can drive the workpiece to rotate relative to the ejector pin. At this time, the workpiece can be automatically rotated without releasing the workpiece clamp, thereby assisting in the polishing process of the workpiece.

[0030] The beneficial effects of the present invention are as follows:

[0031] 1. The present invention utilizes the downward pressing force when clamping the workpiece, so that the bottom plate can be moved downward only by pressing the workpiece downward, and the two locking components are driven close to each other through the action of the adjustment component, so that the workpiece is automatically clamped at the position between the two locking components. The entire clamping process only requires the workpiece to be loaded into the interior of the device as required to complete the automatic clamping, without the need for complicated operations, significantly shortening the tightening time and improving the tightening efficiency.

[0032] 2. The present invention uses cooling gas during the polishing process of the workpiece, and cooperates with the contact between the guide wheel and the bottom end of the workpiece when the workpiece is clamped. By converting the flowing air into the power for the rotation of the guide wheel, the workpiece can be quickly rotated in the clamped state and its polishing position can be changed. The problem of traditional devices requiring the workpiece to be disassembled, rotated and then fixed again is avoided, the entire operation process is simplified, and the overall polishing efficiency is improved.

[0033] 3. The present invention utilizes the input of external cold air to guide the cold air into the interior of the power component, and outputs the cold air from bottom to top to the surface of the workpiece through the transportation of the cooling pipe, so as to quickly cool the surface of the workpiece. At the same time, the rotation of the workpiece can realize rapid cooling of the outer side of the workpiece. At the same time, since the cooling position does not correspond to the polishing position, it will not affect the polishing, thereby improving the polishing quality.

The bottom end of the three-way valve 10 is connected to an external air pump, and the left and right sides of the three-way valve 10 are connected with the two power components 12.

[0047] When polishing a workpiece, the frame 3 can be moved to one side so that the frame 3 is located on one side of the base 1, and the bottom end of the three-way valve 10 is connected to the external air pump, and the parts to be polished are prepared to complete the preparation before polishing;

[0048] When clamping the workpiece, the workpiece can be inserted into the base 1 in parallel, that is, the two ends of the workpiece correspond to the two locking components 6 .

[0049] like Figure 1 and Figure 3 as well as Figure 4 As shown, the locking assembly 6 includes a locking block 601, and the front and rear sides of the locking block 601 near the top are fixedly connected with a clamping block 602, the locking block 601 is movably clamped with the clamping block 602 and the clamping slot 5, and the locking block 601 is displaced left and right relative to the clamping slot 5, the relatively close ends of the two locking blocks 601 are provided with a guide inclined surface 603, a return spring located inside the clamping slot 5 is fixedly connected between the two clamping blocks 602, an adjusting slot 604 is provided in the middle of the locking block 601, and an adjusting block 605 is movably clamped inside the adjusting slot 604, and the adjusting block 605 is displaced up and down relative to the adjusting slot 604, the relatively close ends of the two adjusting blocks 605 are installed with a ejector pin 606, and the relatively far ends of the two locking blocks 601 are vertically installed with an electric push rod 607, the output end of the adjusting slot 604 is connected to the top of the adjusting block 605, and the middle of the bottom end of the locking block 601 is connected to the adjusting assembly 7.

[0050] When the two ends of the workpiece are in contact with the guide slope 603, the two locking blocks 601 are relatively moved away from each other under the guiding action of the guide slope 603, that is, the two locking blocks 601 are displaced relative to the card slot 5 through the card block 602. At this time, the return spring inside the card slot 5 is stretched, and the workpiece continues to move downward until the two ends of the workpiece are in contact with the two ejector pins 606. At this time, the bottom end of the workpiece can be in contact with the two power components 12.

[0051] And according to the diameter of the workpiece, the electric push rod 607 can be turned on to control the adjustment block 605 to move up and down relative to the adjustment slot 604, and at this time, the ejector pin 606 can be driven to move up and down synchronously until the left and right ejector pins 606 are in contact with the middle of the left and right ends of the workpiece, and the corresponding adjustment process can be completed.

[0052] like Figure 2 and Figure 5 as well as Figure 6As shown, the adjustment assembly 7 includes a movable plate 701 located in the middle of the bottom end of the base 1, and first fixed seats 702 are installed on the left and right sides of the top of the movable plate 701, and the end of the first fixed seat 702 away from the movable plate 701 is movably connected to a connecting rod 704 through a rotating shaft, and the end of the connecting rod 704 away from the first fixed seat 702 is movably connected to a second fixed seat 703 through a rotating shaft, the middle part of the top of the movable plate 701 is connected to the bottom end of the extension rod 8, the middle part of the bottom end of the movable plate 701 is connected to the top of the extension frame 11, and the top of the second fixed seat 703 is fixedly connected with a mounting block 705, and the top of the mounting block 705 passes through the top of the through slot and is connected to the bottom end of the locking block 601.

[0053] Embodiment: When the workpiece is inserted into the device in parallel, the bottom end of the workpiece can apply a downward force to the two power components 12. At this time, the bottom plate 9 is displaced downward by the force, and drives the extension rod 8 to move downward, which can drive the movable plate 701 to move downward. At this time, the two connecting rods 704 are deflected, that is, the angle between the two connecting rods 704 and the movable plate 701 is reduced, and at the same time, the two mounting blocks 705 are driven relatively close, and finally the two locking blocks 601 are pulled relatively close. At this time, the two locking blocks 601 can be used to clamp the two ends of the workpiece, so that the bottom end of the workpiece contacts the power component 12, and the two ends of the workpiece contact the two ejector pins 606, completing the clamping process of the workpiece.

[0054] By utilizing the downward pressing force when clamping the workpiece, the bottom plate 9 can be moved downward only by pressing the workpiece downward, and the two locking components 6 are driven close to each other through the action of the adjustment component 7, so that the workpiece is automatically clamped at the position between the two locking components 6. The entire clamping process only requires the workpiece to be loaded into the interior of the device as required to complete the automatic clamping, without the need for complicated operations, which significantly shortens the tightening time and improves the tightening efficiency.

[0055] like Figure 2 and Figure 5 as well as Figure 7 as well as Fig.10 As shown, the power assembly 12 includes a power tank 121, and the two power tanks 121 are symmetrically installed on the front and rear sides of the bottom end of the movable plate 701 through a machine base. The bottom ends of the two power tanks 121 are connected to the left and right sides of the three-way valve 10, and the top ends of the power tanks 121 are fixedly connected to the cooling pipe 128 located below the through groove.

[0056] During the polishing process of the workpiece, cold air can be input into the interior of the three-way valve 10 by turning on the external air pump, and enter the interior of the two power components 12 after being distributed at both ends of the three-way valve 10. At this time, the cold air can enter through the bottom end of the power tank 121 and be discharged through the top end of the power tank 121, that is, discharged through the cooling pipe 128. At this time, the discharged cold air can directly act on the bottom end position of the outer side of the workpiece to quickly cool the surface of the workpiece and complete the cooling process.

[0057] By utilizing the input of external cold air, the cold air is guided into the interior of the power component 12, and the cold air is output from bottom to top to the surface of the workpiece through the transportation of the cooling pipe 128, so that the surface of the workpiece is quickly cooled. At the same time, the rotation of the workpiece can achieve rapid cooling of the outer side of the workpiece. At the same time, since the cooling position does not correspond to the polishing position, it will not affect the polishing, thereby improving the polishing quality.

[0058] like Figure 5 and Figure 7 as well as Fig. 9 and Fig.10 As shown, the middle part of the power tank 121 is movably connected with the first transmission shaft 123, and the outer side surface of the first transmission shaft 123 is fixedly sleeved with the impeller 122 located inside the power tank 121. The power assembly 12 also includes a guide wheel 127 located inside the through groove of the bottom plate 9, and the left and right sides of the bottom end of the outer side surface of the guide wheel 127 are provided with mounting frames 126, and the top of the mounting frame 126 is connected to the bottom end of the bottom plate 9. The middle part of the guide wheel 127 is fixedly sleeved with the second transmission shaft 124, and the second transmission shaft 124 passes through one side of the mounting frame 126 and is movably connected with the two mounting frames 126. The left and right sides of the second transmission shaft 124 are movably sleeved with a synchronous belt 125, and the other end of the synchronous belt 125 is movably sleeved with the left and right sides of the outer side surface of the first transmission shaft 123, and the first transmission shaft 123 is transmission-connected to the second transmission shaft 124 through the synchronous belt 125.

[0059] Embodiment: When cold air enters the interior of the power tank 121, the flowing cold air can drive the impeller 122 to rotate. When the impeller 122 rotates, it can drive the first transmission shaft 123 to rotate rapidly, and at the same time drive the second transmission shaft 124 to rotate through the synchronous belt 125. When the second transmission shaft 124 rotates, the guide wheel 127 located on the outer side of the second transmission shaft 124 rotates accordingly. Since the outer side of the guide wheel 127 is in contact with the outer side of the workpiece, when the guide wheel 127 rotates, the workpiece can be driven to rotate by relying on the friction force, thereby assisting in completing the polishing process of the workpiece.

[0060] By using cooling gas in the process of polishing the workpiece, and coordinating the contact between the guide wheel 127 and the bottom end of the workpiece when the workpiece is clamped, and converting the flowing air into the power for the rotation of the guide wheel 127, the workpiece can be quickly rotated in the clamped state and its polishing position can be changed, thereby avoiding the problem of traditional devices requiring the workpiece to be disassembled, rotated and then fixed again, simplifying the entire operation process and thereby improving the overall polishing efficiency.

[0061] A polishing method for a laser polishing device comprises the following steps:

[0062] S1: When polishing the workpiece, the frame 3 can be moved to one side of the base 1 by moving the frame 3. At this time, the two ends of the workpiece can be aligned with the two locking components 6 and inserted into the workpiece in parallel. At this time, the two ends of the workpiece can contact between the guide slopes 603, and the two locking blocks 601 are relatively separated by the guiding effect of the guide slopes 603. Under the action of the reset spring, the two locking blocks 601 are brought close to each other, so that the two ends of the workpiece are fixed at the position between the two ejector pins 606.

[0063] S2: At this time, the bottom end of the workpiece can contact the outer side of the guide wheel 127, and the electric push rod 607 can be turned on to adjust the upper and lower positions of the adjustment block 605, so that the ejector pin 606 contacts the middle of the end surface of the workpiece. At the same time, when the workpiece is clamped, the bottom plate 9 and the extension rod 8 move downward, and drive the movable plate 701 to move downward, and at the same time drive the two mounting blocks 705 to move relatively close, and assist the two locking blocks 601 to move relatively close, so as to complete the clamping process of the workpiece;

[0064] S3: After the workpiece is clamped, the laser polisher 4 can be turned on, and the left and right displacement of the frame 3 and the front and rear displacement of the laser polisher 4 can be controlled to polish different positions of the workpiece. At the same time, during the polishing process, the external air pump can be turned on to input cold air into the inside of the three-way valve 10, and enter the inside of the power tank 121 through the three-way valve 10, and be discharged through the cooling pipe 128 to act on the bottom end of the workpiece, thereby completing the cooling process of the workpiece during polishing;

[0065] S4: When cold air enters the interior of the power tank 121, it can drive the impeller 122 to rotate. At this time, the first transmission shaft 123 rotates accordingly, and drives the second transmission shaft 124 to rotate through the synchronous belt 125. At this time, the guide wheel 127 at the top rotates accordingly.
