Description

Technical Field

[0002] With the rapid development of modern manufacturing industry, the performance requirements for mechanical parts, especially cutting tools, are increasing. In order to extend the service life of cutting tools and improve cutting efficiency, laser cladding technology, as an advanced surface modification method, has been widely used in the manufacturing process of various high-performance cutting tools. Laser cladding uses a high-energy laser beam to instantly heat a specific powder material to a molten state, and quickly cools and solidifies it on the surface of the tool base material, forming an alloy layer with excellent wear resistance, corrosion resistance and heat resistance, thereby significantly improving the overall performance of the tool.

[0003] Although laser cladding technology brings many advantages, there are still some obvious shortcomings in the traditional tool high-speed laser cladding process. Specifically, in order for the laser cladding equipment to operate smoothly, the following steps are usually required: First, the operator needs to manually place the batch of tools neatly on a special fixed plate in the specified direction; then, the operator needs to use a pressing plate or similar tools to firmly fix the placed tools on the fixed plate to prevent displacement during subsequent transportation; finally, the operator needs to move the fixed plate with the tools to the working area of ​​the laser cladding equipment. However, the above operation process is not only time-consuming and labor-intensive, inefficient, but also increases the possibility of human error, and is also accompanied by high labor costs.

[0033] See also Figure 5-Figure 7As shown, the rotating mechanism includes a support frame 1001, a sleeve 1002, a second electric push rod 1003, a servo motor 1004 and a connecting frame 1005; the support frame 1001 is installed on the right side of the top of the second conveyor 4, and the front side of the top of the support frame 1001 is connected to the controller 13; the sleeve 1002 is installed in the middle of the upper side of the support frame 1001; the second electric push rod 1003 is arranged in the sleeve 1002, and the second electric push rod 1003 is electrically connected to the controller 13; the servo motor 1004 is connected to the telescopic rod of the second electric push rod 1003, and the servo motor 1004 is electrically connected to the controller 13; the output shaft of the servo motor 1004 is connected to the electromagnet 11, and the electromagnet 11 is electrically connected to the controller 13. Connect; Two connecting frames 1005 are installed on the sleeve 1002, and the two connecting frames 1005 are respectively connected to the two distance sensors in the detection device 12, and the two distance sensors are distributed on the left and right. The distance sensor on the right is used to position the tool transported by the second conveyor 4, and the distance sensor on the left is used to sense the distance between the tool and the blade. If the tool is placed in a normal direction, the distance detected by the distance sensor on the left should be the distance between itself and the blade, and this value is the preset value of the distance sensor on the left. If the tool is placed in the opposite direction, the distance detected by the distance sensor on the left is the distance between itself and the top of the tool, and the top of the blade is slightly lower than the top of the tool. Therefore, this value is smaller than the preset value.

[0034] See also Figure 8 As shown, the clamping mechanism includes a third electric push rod 1501 and a clamping block 1502; the third electric push rod 1501 is installed in the middle of the upper left side of the first conveyor 1; the clamping block 1502 is connected to the telescopic rod of the third electric push rod 1501, and the clamping block 1502 is used to clamp the tool on the support plate 2.

[0035] When in use, firstly, according to the height of the tool, twist the first screw 8 to rotate forward or reverse, thereby driving the height limit block 7 to rise or fall, so as to adjust the distance between the bottom of the height limit block 7 and the conveyor belt of the second conveyor 4, until this distance is consistent with the height of the tool. During this period, the operator can cooperate with the scale on the front side of the guide frame 6 to assist in adjusting the height limit block 7. After adjustment, loosen the first screw 8, and then twist the second screw 9033 to rotate forward or reverse, thereby driving the lifting frame 9032 and the electric roller 904 to rise or fall, so as to adjust The distance between the bottom of the electric roller 904 and the transfer table 9031 is adjusted until this distance is consistent with the height of the tool. After the adjustment is completed, the second screw 9033 is loosened, and then the limiting bar 907 is driven to move downward by the first electric push rod 906 until the limiting bar 907 contacts the support plate 2; then, according to the length of the tool, the third screw 909 is twisted to rotate forward or reverse, thereby driving the limiting frame 908 to move left or right, so as to adjust the position of the limiting frame 908 on the top of the support plate 2 until the left side of the limiting frame 908 is aligned with the left side of the support plate 2. The spacing between them is consistent with the length of the tool. After adjustment, the third screw 909 is loosened; then the batch of tools are placed in the U-shaped plate 5 (the side of the blade to be laser clad faces upward), so that the batch of tools falls on the conveyor belt of the second conveyor 4, and then the second conveyor 4 is controlled to convey the batch of tools to the right. When the multi-layer stacked tools pass through the height limit block 7, the height limit block 7 will block the excess tools to ensure that only one layer of tools passes through each time. When the stacked tools are separated from the tools below, the stacked tools will fall down on the conveyor belt of the second conveyor 4. When the tool contacts the guide plate 901 after passing through the height limit block 7, the guide plate 901 will guide the tool to approach the magnetic strip on the second conveyor 4, so that it contacts the magnetic strip, so that the magnetic strip of the second conveyor 4 adsorbs the tool, and the magnetic strip of the second conveyor 4 brings the tool out from between the two guide plates 901 to the right in sequence. During this period, when the front and rear ends of the tool contact the two guide plates 901 respectively, the third conveyor 902 accelerates the movement of the rear end of the tool, so that the tool gradually rotates to be parallel to the magnetic strip of the second conveyor 4, so as to avoid the tool being stuck between the guide plates 901.When the magnetic strip of the second conveyor 4 continues to transport the tool to the right, the tool will move to the bottom of the right distance sensor. When the right distance sensor senses the tool, the right distance sensor will sense that the distance between the tool and the tool is less than the preset value. At this time, the right distance sensor will send a signal. After receiving the signal, the controller 13 will control the second conveyor 4 to stop working so that the tool on the second conveyor 4 stops moving (if the tool is in a normal placement state at this time, the blade of the tool is just below the left distance sensor). Then the controller 13 will control the left distance sensor to detect the distance of the tool. If the left distance sensor senses that the distance between the tool and the tool is equal to the preset value, the left distance sensor will send a signal indicating that the placement is correct. When the controller 13 receives the signal, it determines that the placement direction of the tool is normal. Then the controller 13 will control the second conveyor 4 to continue to work normally so that the second conveyor 4 continues to transport the tool on it; if the left distance sensor senses that the distance between the tool and the tool is less than the preset value, the left distance sensor will send a signal indicating that the placement is wrong. When the controller 13 receives the signal, it determines that the placement direction of the tool is opposite. Then the controller 13 will control the second electric push rod 1003 to drive the servo motor The controller 13 controls the electromagnet 11 to be energized, so that the electromagnet 11 attracts the tool (the magnetic force of the electromagnet 11 must be greater than the magnetic force of the magnetic strip of the second conveyor 4). Then the controller 13 controls the second electric push rod 1003 to drive the servo motor 1004 and the electromagnet 11 to move upward and reset, so that the electromagnet 11 attracts the tool and moves upward, thereby separating the tool from the magnetic strip of the second conveyor 4. Then the controller 13 controls the servo motor 1004 to drive the electromagnet 11 and the tool to rotate 180 degrees so that the tool is facing the correct direction. The controller 13 will control the second electric push rod 1003 again to drive the servo motor 1004 and the electromagnet 11 to move downward, so that the electromagnet 11 attracts the tool and moves downward until the tool contacts the magnetic strip of the second conveyor 4 again, and then the controller 13 will control the electromagnet 11 to cut off the power, so that the electromagnet 11 releases the tool, and then the controller 13 will control the second electric push rod 1003 again to drive the servo motor 1004 and the electromagnet 11 to move upward and reset, so that the electromagnet 11 is separated from the tool, and then the controller 13 will control the second conveyor 4 to continue to work normally, so that the second conveyor 4 continues to transport the tool thereon;When the tool is in the correct placement and moves to the right, the tool will contact the guide bar 905, and the guide bar 905 will guide the tool to the top of the transfer table 9031. When the tool contacts the electric roller 904, the tool on the top of the transfer table 9031 is driven by the electric roller 904 to continue to be transported to the right until the tool moves to the top of the support plate 2 to the right. When the tool contacts the limit bar 907, the limit bar 907 will guide the tool to enter the specified position of the support plate 2, and the limit frame 908 will ensure that the tool stays accurately. The magnetic plate 3 adsorbs the tool on the top of the support plate 2 and can fix the tool. In this way, the tool can be automatically loaded; then the support plate 2 is intermittently transported by the first conveyor 1, so as to drive the tool on the support plate 2 to move. When the tool on the support plate 2 comes to the bottom of the clamping block 1502, the clamping block is driven by the third electric push rod 1501. 1502 moves downward until the clamping block 1502 clamps the tool on the support plate 2, thereby reinforcing the tool on the support plate 2, and then the laser cladding equipment can be used to perform high-speed laser cladding on the tool on the support plate 2. After the tool on the support plate 2 completes high-speed laser cladding, the third electric push rod 1501 drives the clamping block 1502 to move upward and reset, so that the clamping block 1502 releases the tool. After that, when the first conveyor 1 drives the tool on the support plate 2 that has completed laser cladding to contact the shovel plate 14, the shovel plate 14 will shovel the tool on the support plate 2 that has completed laser cladding, so that the tool that has completed laser cladding is separated from the support plate 2, so that the tool that has completed laser cladding falls down onto the shovel plate 14 to slide and discharge, so that the tool can be automatically unloaded, thereby realizing automatic loading and unloading of tools, so that the tools can be automatically laser clad in batches. ;

[0036] See also Fig.10 As shown, it also includes a cleaning mechanism, which includes an electric cleaning roller 16, a rubber cylinder 17 and an arc block 18; an electric cleaning roller 16 for cleaning the surface of the tool is installed in the middle of the lifting frame 9032; a rubber cylinder 17 is also placed on the upper side of the lifting frame 9032, and the rubber cylinder 17 is in contact with the electric cleaning roller 16, and the rubber cylinder 17 is used to adhere to the dust on the surface of the electric cleaning roller 16; the left ends of the two arc blocks 18 are symmetrically rotated front and back and are arranged on the upper side of the lifting frame 9032, and the right ends of the two arc blocks 18 are fixed to the upper side of the lifting frame 9032 by bolts, and the arc block 18 is used to limit the rubber cylinder 17.

[0037] By setting up a cleaning mechanism, when the tool passes over the top of the transfer table 9031, the electric cleaning roller 16 can clean the dust on the surface of the tool, thereby cleaning the blade, so as to facilitate the subsequent laser cladding of the blade, and the rubber cylinder 17 can adhere to the dust on the surface of the electric cleaning roller 16, thereby cleaning the dust on the surface of the electric cleaning roller 16, so as to prevent the dust on the surface of the electric cleaning roller 16 from affecting the cleaning of the subsequent tool. After that, when too much dust adheres to the surface of the rubber cylinder 17, the bolts on the arc block 18 can be removed, and then the arc block 18 can be rotated to unfold, and then the rubber cylinder 17 can be removed, and another new rubber cylinder 17 can be put back to its original place, and then the arc block 18 can be reversed and retracted, and then the arc block 18 can be fixed with bolts, so that the arc block 18 can limit the rubber cylinder 17, thereby completing the replacement of the rubber cylinder 17.

[0038] See also Fig.11 and Fig.12 As shown, it also includes a blocking mechanism, which includes a bracket 19, a blocking film 20 and a counterweight bar 21; two brackets 19 are installed on the left side of the top of the first conveyor 1; the blocking film 20 is connected to the upper side of the bracket 19, and the blocking film 20 is a ceramic coating film (with high temperature resistance, when resisting slag, it can effectively prevent the film material itself from being melted), and the blocking film 20 is used to block the slag splashed during the laser cladding of the tool; the bottom end of the blocking film 20 is connected to the counterweight bar 21.

[0039] When the first conveyor 1 drives the support plate 2 and the tool to move, the support plate 2 and the tool will contact the blocking film 20. At this time, the support plate 2 and the tool will squeeze the blocking film 20 to deform and flip up. When the support plate 2 and the tool are separated from the blocking film 20, under the gravity of the counterweight bar 21, the counterweight bar 21 will drive the blocking film 20 to return to its original state. When the tool on the support plate 2 is laser cladding, the blocking film 20 can block the slag splashed during the laser cladding of the tool, thereby preventing the slag from flying to the tool next to it and affecting the quality.

[0040] See also Fig.11 and Fig.12 As shown, a cooling mechanism is also included, which includes a cover 22, a fan 23 and an air pipe 24; the front side of the clamping block 1502 is connected to the cover 22, and the cover 22 is used to cover the tool on the support plate 2; a fan 23 is installed on the upper left side of the first conveyor 1, and the fan 23 is located in front of the third electric push rod 1501, and the air outlet of the fan 23 is connected to the cover 22 through the air pipe 24, and the air pipe 24 is a hose.

[0041] When the clamping block 1502 moves up and down, the clamping block 1502 will drive the covering cover 22 to move up and down synchronously. When the clamping block 1502 is clamping the tool, the covering cover 22 will synchronously cover the previous tool that has completed laser cladding. Later, when the tool clamped by the clamping block 1502 is undergoing laser cladding, air can be blown into the air pipe 24 and the covering cover 22 through the fan 23 at the same time, so as to cool the tool in the covering cover 22.
