Description

An automatic grooving machine Technical Field

[0001] This invention relates to the field of grooving technology for parts, and more particularly to an automatic grooving machine. Background Technology

[0002] The production process of a machine refers to the entire process of transforming raw materials (or semi-finished products) into finished products. For machine production, this includes the transportation and storage of raw materials, production preparation, blank manufacturing, parts processing and heat treatment, product assembly and debugging, painting, and packaging. The production process is very broad. Modern enterprises use the principles and methods of systems engineering to organize and guide production, viewing the production process as a production system with inputs and outputs. In the production process, any process that changes the shape, size, position, and properties of the production object to make it a finished or semi-finished product is called a technological process. It is the main part of the production process. Technological processes can be further divided into casting, forging, stamping, welding, machining, assembly, and other technological processes.

[0003] Currently, one step in machining is to slot parts. The traditional method of machining parts is to manually drill holes and slot, which is very inefficient, imprecise, and difficult to mass-produce.

[0004] Therefore, there is a need to provide an automatic grooving machine to solve the above problems. Summary of the Invention

[0005] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide an automatic grooving machine that automatically grooves parts, ensuring the efficiency and accuracy of grooving and improving production efficiency.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: an automatic grooving machine, including an equipment frame and a robot; the robot can sequentially move parts to a marking mechanism, at least one set of grooving components, a grinding component, and a CCD detection component; the marking component includes a laser marking component and a laser stage component with corresponding positions; the grooving component includes a part positioning mechanism and a tool lifting component; the tool lifting component drives a vertically arranged tool on it to move up and down to groove the part; the grinding component includes a grinding component and a moving component that moves the part to the grinding component for grinding.

[0007] Furthermore, the laser marking assembly includes a two-axis adjustable component and a laser marking head. The two-axis adjustable component can adjust the position of the laser marking head in the horizontal and vertical directions. The two-axis adjustable component includes an X-axis adjustable module and a Z-axis adjustable module, with the laser marking head located on the X-axis adjustable module. By cooperating with the Z-axis and X-axis adjustable components, the position of the laser marking head is adjusted, thereby accurately marking the parts on the laser stage assembly and ensuring the accuracy of the subsequent grooving positions on the parts.

[0008] Furthermore, the laser stage assembly includes a stage support located on the equipment frame and a rotary cylinder horizontally mounted on the stage support. The rotary cylinder drives the mounting plate to rotate, causing at least one gripper cylinder located on the mounting plate to change position. The gripper cylinder is used to clamp the parts to be marked. By changing the position of the gripper cylinder through the rotary cylinder, the marking efficiency of the parts can be effectively improved.

[0009] Furthermore, the grooving assembly is located on the mounting bracket, and the part positioning mechanism includes a fixed support for placing the part, a horizontal clamping assembly for the part, and a vertical clamping assembly for the part. The horizontal clamping assembly includes a horizontal clamping cylinder and a horizontally arranged movable clamping block. The piston rod of the horizontal clamping cylinder extends and retracts, driving the movable clamping block, which passes through the fixed support, to move towards or away from the tool. A hook is provided at the end of the movable clamping block closest to the fixed support, facing upwards. The horizontal clamping assembly is symmetrically arranged along the centerline of the fixed support's length direction. When the horizontal clamping cylinder drives the piston rod to extend, the movable clamping block moves horizontally away from the tool. The hook on the movable clamping block clamps the part between the inner wall of the hook and the fixed support, achieving horizontal positioning of the part.

[0010] Furthermore, the mounting bracket includes a vertically arranged partition and a horizontally arranged fixing plate on the equipment frame. The vertical clamping assembly for the part includes a vertically arranged pressing cylinder. The top end of the piston rod of the pressing cylinder is fixedly connected to the mounting plate through a cylinder fixing component. A pressing plate is horizontally fixed on the housing of the pressing cylinder. The end of the pressing plate away from the pressing cylinder is hinged to a fixed support through a hinge component. When the piston rod of the pressing cylinder extends, the pressing head end of the pressing plate presses the part down onto the fixed support from top to bottom. This achieves vertical positioning of the part. After positioning, the tool lifting assembly can drive the tool to move downward to groove the marking position on the part.

[0011] Furthermore, the fixed support is provided with a part feeding guide groove and a pushing assembly on both sides along its width direction. The pushing assembly includes a pushing cylinder and a cylinder support. By setting the pushing assembly, the slotted part can be automatically pushed out of the part positioning mechanism, making it convenient for the robot to grip and transfer it to the next workstation.

[0012] Furthermore, the grinding assembly also includes a loading assembly and a unloading assembly, which are structurally identical and located on both sides of the grinding assembly. The loading assembly includes a lifting cylinder vertically mounted on the equipment frame. The top of the piston rod of the lifting cylinder is fixedly connected to a clamping cylinder via a transition plate. A clamping plate is provided on the top of the piston rod of the clamping cylinder. An alignment platform for placing parts is provided on the housing of the clamping cylinder. A clamping plate is provided on the alignment platform. When the piston rod of the clamping cylinder retracts, it can clamp the parts between clamping plates one and two. The distance between the parts located between clamping plates one and two and the grinding assembly in the height direction is adjusted by the lifting cylinder to ensure that the bottom of the parts can be completely ground.

[0013] Furthermore, the moving assembly includes a clamping assembly for clamping the part and a displacement assembly for driving the clamping assembly to move back and forth between the loading assembly and the unloading assembly. The grinding assembly includes a drive motor and a drive wheel located at the rotating shaft end of the drive motor. The grinding belt is tensioned by the drive wheel and several driven wheels. When the displacement assembly moves the clamped part toward the grinding belt, the grinding belt rotates under the drive of the drive wheel and the driven wheels, so that the bottom of the part can be ground when it moves onto the grinding belt. It should be emphasized that the direction of movement of the part is opposite to the transmission direction of the grinding belt. Therefore, bottom grinding can be achieved during the movement of the part. When the part moves to the alignment platform on the unloading assembly under the drive of the clamping assembly, it indicates that the bottom grinding of the part is completed.

[0014] Furthermore, the CCD inspection component includes a CCD camera located on the equipment frame. The side of the CCD camera is fixedly connected to the gripper cylinder two via a connecting plate, and the gripper of the gripper cylinder two is positioned above the CCD camera. The part is clamped by the gripper cylinder two, and the CCD camera takes a picture of the grooved area of ​​the part to detect whether the grooved position of the part is accurate.

[0015] Furthermore, the equipment frame is also provided with a feeding carrier with multiple placement slots. The feeding carrier is located on the side of the grinding assembly, and the feeding carrier has material tray handles on both sides for easy handling.

[0016] The beneficial effects of this invention are:

[0017] This invention utilizes the coordinated operation of a laser marking component, a laser stage component, a grooving component, a grinding component, a CCD detection component, and a material unloading carrier. The laser stage component positions the part, the laser marking component marks the areas on the part that require grooving, ensuring the accuracy of the grooving position; the grooving component automatically grooves the part, ensuring efficient grooving; and the grooved part is then ground by the grinding component and photographed and inspected by the CCD detection component, further improving the processing efficiency of the part.

Detailed Implementation

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0028] Referring to Figures 1 to 8, an automatic grooving machine in this embodiment includes a device frame 1 and a robot 4. The robot 4 can sequentially move parts to a marking mechanism, at least one set of grooving components 5, a grinding component 9, and a CCD detection component 10. The marking component includes a laser marking component 2 and a laser stage component 3 with corresponding positions. The marking mechanism marks the positions on the parts that need to be grooved, ensuring the accuracy of the grooving position of the parts.

[0029] The grooving assembly 5 includes a part positioning mechanism and a tool lifting assembly 51. The tool lifting assembly 51 drives the vertically mounted tool 52 to move up and down to groove the part. The grooving assembly 5 is provided with three sets, and the material of each set of tools is different, which can groove parts of different materials without frequent tool replacement, thus effectively improving the work efficiency of part grooving.

[0030] The grinding component 9 includes a grinding component 96 and a moving component that transfers the part to the grinding component 96 for grinding. After the grooved part is ground by the grinding component 96 and photographed and inspected by the CCD detection component 10, the processing accuracy of the part can be improved, and the processing efficiency of the part can also be improved.

[0031] The laser marking assembly 2 includes a two-axis adjustable component 21 and a laser marking head 22. The two-axis adjustable component 21 can adjust the position of the laser marking head 22 in the horizontal and vertical directions. The two-axis adjustable component 21 includes an X-axis adjustable module 221 and a Z-axis adjustable module 222, with the laser marking head 22 located on the X-axis adjustable module 221. By cooperating with the Z-axis adjustable component 221 and the X-axis adjustable component 222, the position of the laser marking head 22 is adjusted, thereby accurately marking the parts on the laser stage assembly 3 and ensuring the accuracy of the slotting position on the subsequent parts.

[0032] The laser stage assembly 3 includes a stage support 31 located on the equipment frame 1 and a rotary cylinder 32 horizontally arranged on the stage support 31. The rotary cylinder 32 drives the mounting plate 33 to rotate, thereby changing the position of at least one gripper cylinder 34 located on the mounting plate 33. The gripper cylinder 34 is used to clamp the parts that need to be marked. By changing the position of the gripper cylinder 34 through the rotary cylinder 32, the marking efficiency of the parts can be effectively improved.

[0033] The slotting assembly 5 is located on the mounting bracket 6. The part positioning mechanism includes a fixed support 56 for placing the part, a horizontal clamping assembly 55 for the part, and a vertical clamping assembly 57 for the part. The horizontal clamping assembly 55 includes a horizontal clamping cylinder 551 and a horizontally arranged movable clamping block 552. The piston rod of the horizontal clamping cylinder 551 extends and retracts, driving the movable clamping block 552, which passes through the fixed support 56, to move towards or away from the tool. A hook 553 is provided at the end of the movable clamping block 552 near the fixed support 56, facing upwards. The horizontal clamping assembly 55 is symmetrically arranged along the centerline of the fixed support 56. When the horizontal clamping cylinder 551 drives the piston rod to extend, the movable clamping block 552 moves horizontally away from the tool. The hook 553 on the movable clamping block 552 can clamp the part between the inner wall of the hook 553 and the fixed support 56, thereby achieving horizontal positioning of the part.

[0034] The mounting bracket 6 includes a vertically arranged partition 7 and a horizontally arranged fixing plate 8 on the equipment frame 1. The vertical pressing assembly 57 for the part includes a vertically arranged pressing cylinder 571. The top end of the piston rod of the pressing cylinder 571 is fixedly connected to the mounting plate 33 through a cylinder fixing member 573. A pressing plate 572 is horizontally fixed on the housing of the pressing cylinder 571. The end of the pressing plate 572 away from the pressing cylinder 571 is hinged to the fixed support 56 through a hinge member 574. When the piston rod of the pressing cylinder 571 extends, the pressing head end of the pressing plate 572 presses the part down onto the fixed support 56 from top to bottom. This achieves vertical positioning of the part. After positioning, the tool lifting assembly 51 can drive the tool to move downward to groove the marking position on the part. The tool lifting assembly 51 can be a lifting cylinder or a lifting module, etc., as long as it can realize the lifting and grooving of the tool 52. The specific structure is not limited.

[0035] The fixed support 56 is provided with a part feeding guide groove 53 and a pushing assembly 54 on both sides along its width direction. The pushing assembly 54 includes a pushing cylinder 541 and a cylinder support 542. By setting the pushing assembly 54, the slotted part can be automatically pushed out of the part positioning mechanism, which is convenient for the robot 4 to pick up and transfer to the next station.

[0036] Referring to Figures 7 and 8, the grinding assembly 9 also includes a loading assembly 93 and a unloading assembly, which are structurally identical and located on both sides of the grinding assembly 96. The loading assembly 93 includes a lifting cylinder 931 vertically mounted on the equipment frame 1. The top of the piston rod of the lifting cylinder 931 is fixedly connected to the clamping cylinder 932 via a transition plate. A clamping plate 933 is provided on the top of the piston rod of the clamping cylinder 932. An alignment platform 94 for placing parts is provided on the housing of the clamping cylinder 932. A clamping plate 95 is provided on the alignment platform 94. When the piston rod of the clamping cylinder 932 retracts, it can clamp the parts between the clamping plate 933 and the clamping plate 95. The distance between the parts located between the clamping plate 933 and the clamping plate 95 and the grinding assembly 96 in the height direction is adjusted by the lifting cylinder 931 to ensure that the bottom of the parts can be completely ground.

[0037] The moving assembly includes a clamping assembly 92 for clamping parts and a displacement assembly 91 for driving the clamping assembly 92 to reciprocate between the loading assembly 93 and the unloading assembly. The grinding assembly 96 includes a drive motor and a drive wheel 963 located at the rotating shaft end of the drive motor. The grinding belt 962 is tensioned by the drive wheel 963 and several driven wheels 964. When the displacement assembly 91 moves the clamped part toward the grinding belt 962, the grinding belt 962 rotates under the drive of the drive wheel 963 and the driven wheels 964, so that the bottom of the part can be ground when it moves onto the grinding belt 962. It should be emphasized that the direction of movement of the part is opposite to the transmission direction of the grinding belt 962. Therefore, bottom grinding can be achieved during the movement of the part. When the part moves to the alignment platform 94 on the unloading assembly under the drive of the clamping assembly 92, it indicates that the bottom grinding of the part is completed. The clamping assembly 92 is a clamping cylinder, and the moving assembly 91 is a linear module.

[0038] Referring to Figure 2, the CCD inspection assembly 10 includes a CCD camera located on the equipment frame 1. The side of the CCD camera 101 is fixedly connected to the gripper cylinder 102 via a connecting plate 103, and the gripper of the gripper cylinder 102 is positioned above the CCD camera 101. The part is clamped by the gripper cylinder 102, and the CCD camera 101 takes a picture of the grooved area of ​​the part to detect whether the grooved position of the part is accurate.

[0039] The equipment frame 1 is also provided with a feeding carrier 11 having multiple placement slots. The feeding carrier 11 is located on the side of the grinding component 9, and the feeding carrier 11 has material tray handles 12 on both sides for easy handling.

[0040] Working principle: First, robot 4 grasps the part to be grooved and places it on the laser marking stage assembly. The gripping cylinder clamps the part. After clamping, the two-axis adjustable assembly 21 moves the laser marking head 22 above the part and marks the required grooving position, effectively ensuring accurate grooving during subsequent grooving. The laser stage assembly 3 is equipped with two sets of gripper cylinders 34. The position of the gripper cylinders 34 can be changed by rotating cylinder 32, improving the efficiency of part marking.

[0041] After the part is marked, robot 4 picks up the part and pushes it through the part feeding guide groove 53 on the slotting assembly 5 to the fixed support 56. The horizontal clamping assembly 55 starts working. When the horizontal clamping cylinder 551 drives the piston rod to retract, the moving clamping block 552 moves horizontally away from the tool. The hook 553 on the moving clamping block 552 can clamp the part between the inner wall of the hook 553 and the fixed support 56, realizing the horizontal positioning of the part. After the horizontal positioning is completed, the vertical pressing assembly 57 starts working. The piston rod of the pressing cylinder 571 extends, and the housing of the pressing cylinder 571... The body moves upward, thereby causing one end of the lower pressure plate 572 connected to it to move upward. The lower pressure plate 572 is hinged to the fixed support 56 through a hinge 574. Therefore, the pressure head end of the lower pressure plate 572 presses downward, pressing the part tightly onto the fixed support 56 from top to bottom, achieving vertical positioning of the part. After positioning, the tool lifting assembly 51 can drive the tool to move downward to groove the marking position of the part. The tools on the several grooving assemblies 5 are made of different materials, which can adapt to the grooving processing of parts made of various different materials. There is no need to frequently change tools, which effectively improves the practicality of the invention and the grooving efficiency of the parts.

[0042] After the part is slotted, the pusher cylinder 541 pushes the part out of the part loading guide 53. The robot 4 picks up the slotted part and moves it to the grinding assembly 9 to grind the lower surface of the slotted part. The part to be ground is picked up and placed on the alignment platform 94. The piston rod of the clamping cylinder 932 extends and clamps the part between the first clamping plate 933 and the second clamping plate 95 on the alignment platform 94. At this time, the positioning of the part to be ground is completed. The displacement assembly 91 drives the clamping assembly 92 to move above the part and clamp it. The part is moved towards the grinding assembly 96. The grinding belt 962 rotates under the drive of the drive wheel 963 and the driven wheel 964, so that the bottom of the part can be ground when it moves onto the grinding belt 962. The moving direction of the part is opposite to the transmission direction of the grinding belt 962. Therefore, the bottom can be ground during the movement of the part. When the part moves to the alignment platform 94 on the unloading assembly under the drive of the clamping assembly 92, it indicates that the bottom grinding of the part is completed.

[0043] After grinding, robot 4 moves the part to CCD detection component 10. The part is clamped by gripper cylinder 2 102, and CCD camera 101 takes a picture of the grooved area of ​​the part to check if the grooved position is accurate. Parts that meet the grooving requirements are picked up by robot 4 and placed into the placement slot on the unloading carrier 11 for unified collection. The entire grooving process of the part does not require manual operation, effectively improving the processing efficiency of the part and reducing the labor intensity of the workers.

[0044] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
