Description

Technical Field

[0001] This invention relates to the field of gray cast iron parts processing technology, specifically to a surface treatment and grinding device for gray cast iron parts production. Background Technology

[0002] Gray cast iron, due to its excellent casting properties, vibration damping, and wear resistance, is widely used in the production of basic components such as fluid control equipment and industrial flanges. In the manufacturing of some complex or customized gray cast iron parts, to meet the needs of subsequent docking or multi-component assembly, multiple gray cast iron connectors are typically welded circumferentially at equal intervals around the main gray cast iron component. After these connectors are welded and cured to the main body, the reserved process positioning length needs to be uniformly cut. The cut end faces will retain relatively rough cutting marks and welding spatter; therefore, the multiple circumferentially distributed cut end faces need to be surface-ground to meet the precision requirements of subsequent assembly.

[0003] In actual production, the grinding process for the end faces of such ring-shaped gray cast iron connectors usually relies on operators using handheld angle grinders or other grinding tools to process them one by one. During operation, the worker needs to measure and locate the ring-shaped grinding points on the workpiece one by one, and then grind the end face of each connector in sequence until all the end faces of the connectors are ground flat.

[0004] The above methods have the following shortcomings: First, manual point-by-point measurement, positioning, and grinding are time-consuming, and when faced with gray cast iron parts of different specifications and processing radii, it is impossible to achieve rapid size adaptation and complete multi-point synchronous processing at one time, thus restricting production efficiency. Second, whether it is manual grinding or multi-head equipment driven by multiple motors, it is difficult to ensure the synchronicity of the radial displacement of multiple grinding components, which easily leads to pacing errors, causing the grinding points to not be kept on the same circumferential trajectory, affecting the consistency of product quality after grinding. Third, gray cast iron material has weak impact resistance. If the grinding disc makes instantaneous large-area contact with the end face of the workpiece in a horizontal posture, the resulting rigid impact can easily cause the edge of the workpiece to crack, affecting the yield.

[0005] Therefore, the purpose of this invention is to provide a surface treatment and grinding apparatus for the production of gray cast iron parts, so as to overcome the above-mentioned deficiencies in the prior art. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a surface treatment grinding device for the production of gray cast iron parts. It solves the problems of low efficiency, inability to quickly adapt to workpieces of different sizes, inconsistent grinding quality due to reliance on manual point-by-point measurement and positioning during the existing ring-shaped multi-point grinding process of gray cast iron parts, the tendency of multiple drive sources to generate pace errors, and the risk of edge chipping caused by the instantaneous contact of the grinding disc to cause rigid impact on the gray cast iron.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A surface treatment and grinding device for the production of gray cast iron parts includes an operating table, on which a first adjustment component is provided.

The lower surface of the slider is fixedly connected to the fourth adjustment component through a connecting rod. The third adjustment component is used to adapt to the grinding radius of gray cast iron parts of different sizes. The lower surface of the support assembly is provided with a guide assembly, the guide assembly includes a fixed rod, the fixed rod has a groove inside, and the slider is slidably disposed in the groove so that the slider moves linearly in the radial direction; The fourth adjustment component includes a fixed base fixedly connected to the side surface of the connecting rod. A second cylinder is rotatably connected inside the fixed base via a third rotating shaft. A rotating rod is rotatably connected inside the fixed base via a fourth rotating shaft. A fixed block is fixedly connected to the end of the rotating rod away from the fixed base. The interior of the fixed block is rotatably connected to the telescopic output end of the second cylinder via a fifth rotating shaft. A fixed box is fixedly connected to the side surface of the rotating rod. A grinding component is mounted on the fixed box. The fourth adjustment component is used to change the downward pressing shape of the grinding component during grinding contact, so that the grinding component cuts into the gray cast iron part at an inclined angle and gradually flattens it for grinding.

[0008] Preferably, the support assembly includes a first support plate, and a second support plate is fixedly connected to the side surface of the first support plate via a first connecting plate. The first connecting plate and the second support plate are provided in two sets and are symmetrically distributed from left to right. The first adjustment assembly includes a first support column fixed to the upper surface of the operating table, a first fixing plate fixedly connected to the top of the first support column, a first cylinder fixedly connected to the upper surface of the first fixing plate, and the output end of the first cylinder fixedly connected to the support assembly.

[0009] Preferably, the upper surface of the fixing rod is fixedly connected to the lower surface of the corresponding first support plate or second support plate.

[0010] Preferably, a first fixing frame is fixedly connected to the upper surface of the second support plate, the top inner wall of the first fixing frame is fixedly connected to a bearing, and the bearing is sleeved on the side surface of the second rotating shaft; a second fixing frame is fixedly connected to the upper surface of the first support plate, and the upper surface of the second fixing frame is fixedly connected to the drive motor.

[0011] Preferably, the upper surface of the operating table is fixedly connected to a second fixing plate via a second support column, and the lower surface of the second fixing plate is connected to the first connecting plate via a telescopic rod.

[0012] Preferably, the operating table is provided with a processing table for placing gray cast iron parts, and a positioning column is fixedly connected to the upper surface of the processing table.

[0013] Preferably, a controller is fixedly connected to the front surface of the operating table via a second connecting plate, and the drive motor, the first cylinder, the second cylinder, and the grinding assembly are all electrically connected to the controller. Preferably, two sets of the third adjustment assembly are provided, respectively arranged below the first support plate and the second support plate.

[0014] This invention provides a surface treatment and grinding device for the production of gray cast iron parts, which has the following beneficial effects: 1. This invention, through the cooperation of a third adjustment component and a guide component, utilizes the guide groove and guide post on the rotating plate to convert the rotational motion of the rotating plate into the radial linear motion of the slider. Furthermore, the radial motion of the slider is constrained by the cooperation of the fixed rod and the sliding groove in the guide component, ensuring that each slider moves only in a radial straight line. This achieves synchronous adjustment of the grinding position and flexible adaptation of the dimensions of the annular multi-point connector. It can adjust the radial working position of the grinding component according to the processing radius requirements of gray cast iron parts of different sizes, eliminating the tedious process of traditional manual point-by-point measurement, positioning, and grinding. It completes multi-point synchronous processing on the workpiece in one go, improving production efficiency. Simultaneously, it keeps all grinding points on the same circumferential trajectory, ensuring consistency in grinding allowance and position.

[0015] 2. This invention utilizes a transmission mechanism between the second and third adjustment components, employing a single drive motor as a unified power source. Power is transmitted to the two rotating shafts via a belt drive, causing the rotating plates on both sides to deflect synchronously. This, in turn, drives each group of third adjustment components to complete synchronous radial expansion or contraction. This single-drive-source, multi-group linkage structure ensures the synchronicity of the radial displacement of each grinding component group from a mechanical transmission perspective. Compared to schemes with multiple motors driving independently, this device eliminates synchronization errors caused by differences in motor start-up timing, response speed, or control precision. The radial displacement of each grinding component group is uniformly determined by the same transmission chain, thus ensuring the consistency of product quality after multi-point grinding of gray cast iron parts.

[0016] 3. This invention incorporates a fourth adjustment component, utilizing a second cylinder to drive a rotating rod to deflect around a fourth axis, thus creating an inclined entry angle for the grinding assembly before feeding. Addressing the characteristics of gray cast iron material—its weak impact resistance and susceptibility to edge chipping under concentrated instantaneous loads—the grinding disc slowly cuts into the workpiece end face at an inclined angle before gradually returning to a horizontal, flattened state to complete the grinding. This feeding method avoids the rigid impact and grinding jumps caused by the grinding wheel's instantaneous large-area contact with the workpiece, which helps protect the edge integrity of the gray cast iron parts. Simultaneously, by buffering the contact reaction force, it extends the service life of the grinding assembly. Attached Figure Description

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Please see the appendix Figure 1 With appendix Figure 2 A surface treatment and grinding device for the production of gray cast iron parts includes an operating table 1. A first adjustment component 2 is mounted on the operating table 1, used to adjust the height of a support component 3. The support component 3 includes a first support plate 301, with a second support plate 303 fixedly connected to the side surface of the first support plate 301 via a first connecting plate 302. Both the first connecting plate 302 and the second support plate 303 are provided in two sets, symmetrically distributed left and right. The first adjustment component 2 includes a first support column 201 fixed to the upper surface of the operating table 1. A first fixing plate 202 is fixedly connected to the top of the first support column 201, and a first cylinder 203 is fixedly connected to the upper surface of the first fixing plate 202. The output end of the first cylinder 203 is fixedly connected to the support component 3.

[0021] The first adjustment component 2 serves as the vertical feed and lifting power source in the Z-axis direction of this device, controlling the cutting depth and overall lifting and resetting of the entire grinding process. When grinding of gray cast iron workpieces is required, the controller 12 issues a command to start the first cylinder 203. The output end of the first cylinder 203 extends downward, pushing the support component 3, which is composed of the first support plate 301, the first connecting plate 302, and the second support plate 303, to move downward as a whole. The first support column 201, the first fixed plate 202, and the first cylinder 203 are symmetrically arranged in two sets. Through the left-right symmetrical frame support structure, it can withstand the downward grinding reaction force generated when multiple points are in contact simultaneously, and ensure the stability of the equipment's center of gravity during the lifting process.

[0022] Please see the appendix Figure 3 To be continued Figure 5 The support assembly 3 is equipped with a second adjustment assembly 4 and multiple sets of third adjustment assemblies 5, all of which are connected to the second adjustment assembly 4. The second adjustment assembly 4 includes a drive motor 401. The output end of the drive motor 401 is fixedly connected to a first pulley 403 via a first rotating shaft 402. A transmission belt 404 is drivenly connected to the side surface of the first pulley 403. A second pulley 405 is drivenly connected to the inner surface of the transmission belt 404. A second rotating shaft 406 is fixedly connected to the inner surface of the second pulley 405. A bearing 407 is fixedly connected to the side surface of the second rotating shaft 406.

[0023] A first fixing frame 408 is fixedly connected to the upper surface of the second support plate 303, and the top inner wall of the first fixing frame 408 is fixedly connected to the bearing 407. A second fixing frame 409 is fixedly connected to the upper surface of the first support plate 301, and the upper surface of the second fixing frame 409 is fixedly connected to the drive motor 401.

[0024] This invention achieves synchronous adjustment of the positions of multiple grinding components 8 on the first support plate 301 and multiple grinding components 8 on the second support plate 303 by setting a second adjustment component 4 and a third adjustment component 5, using a single drive source. When adjusting the ring-shaped machining dimensions, only one drive motor 401 is needed as a unified power source. The drive motor 401 drives the first rotating shaft 402 to rotate, and through the transmission mechanism composed of the first pulley 403, the transmission belt 404 and the second pulley 405, the power is transmitted to the second rotating shaft 406 on the other side, so that the two rotating shafts rotate synchronously. Since the two rotating shafts are driven by the same power source through the same transmission chain, their rotation speed and rotation angle are consistent, thus ensuring the synchronicity of the radial displacement of each group of third adjustment components 5 from a mechanical structure perspective. The first fixing frame 408, in conjunction with the bearing 407, provides axial and radial limiting fixation for the second rotating shaft 406, and the second fixing frame 409 securely mounts the drive motor 401 on the first support plate 301. Together, they provide reliable support for the transmission system, ensuring the concentricity of the transmission system and the stability of long-term operation.

[0025] Please see the appendix Figure 5 With appendix Figure 7 The third adjustment component 5 is used to adapt to the grinding radius of gray cast iron parts of different sizes. In this embodiment, two sets of the third adjustment components 5 are provided, respectively arranged below the first support plate 301 and the second support plate 303. The third adjustment component 5 includes a rotating plate 501. A rotating plate 501 is fixedly connected to the side surface of the first rotating shaft 402 and the second rotating shaft 406. Multiple sets of guide grooves 502 are opened inside the rotating plate 501. Guide posts 503 are provided inside the guide grooves 502. A slider 504 is fixedly connected to the upper surface of the guide post 503. The lower surface of the slider 504 is fixedly connected to the fourth adjustment component 6 through a connecting rod 505.

[0026] When the first rotating shaft 402 and the second rotating shaft 406 rotate synchronously under the constraint of the conveyor belt 404, they drive the rotating plates 501 fixedly connected to their respective side surfaces to rotate circumferentially. The guide groove 502 is a curved groove opened on the rotating plate 501, and its trajectory is configured such that when the rotating plate 501 rotates, the groove wall of the guide groove 502 drives the guide post 503 to move in the radial direction of the rotating plate 501. Since the guide post 503 is engaged in the guide groove 502, the circumferential rotation of the rotating plate 501 applies a thrust along the groove direction to the guide post 503 through the groove wall of the guide groove 502, forcing the guide post 503 and the slider 504 fixedly connected above it to generate radial displacement. Thus, the radial working position of all grinding components 8 can be adjusted synchronously according to the processing radius requirements of gray cast iron parts of different sizes, that is, the different positions of the connecting parts from the center of the workpiece.

[0027] The lower surfaces of the first support plate 301 and the second support plate 303 are provided with guide components 7. The guide components 7 include a fixed rod 701. The fixed rod 701 has a groove 702 inside. The inner surface of the groove 702 is slidably connected to the slider 504. The upper surface of the fixed rod 701 is fixedly connected to the lower surface of the corresponding first support plate 301 or second support plate 303.

[0028] When the rotating plate 501 converts the rotational force into a radial thrust on the slider 504, a lateral component force is generated between the guide post 503 and the connecting rod 505. By opening a groove 702 inside the fixed rod 701 that slides with the slider 504, and by fixing the upper surface of the fixed rod 701 to the corresponding support plate, the slider 504 can only move radially in a straight line along the direction set by the groove 702. This constrains the sway caused by the lateral component force, ensuring that each grinding assembly 8 moves in the same radial direction, and keeping each grinding point on the same circumferential trajectory.

[0029] Please see the appendix Figure 6A fourth adjustment component 6 is provided on the third adjustment component 5, and a grinding component 8 is installed on the fourth adjustment component 6. The fourth adjustment component 6 is used to change the downward pressing shape of the grinding component 8 during grinding contact, so that the grinding component 8 cuts into the gray cast iron part at an inclined angle and gradually flattens it for grinding. The fourth adjustment component 6 includes a fixed seat 601 fixedly connected to the side surface of the connecting rod 505. The interior of the fixed seat 601 is rotatably connected to the second cylinder 603 through the third rotating shaft 602. The interior of the fixed seat 601 is rotatably connected to the rotating rod 605 through the fourth rotating shaft 604. The end of the rotating rod 605 away from the fixed seat 601 is fixedly connected to the fixed block 606. The interior of the fixed block 606 is rotatably connected to the telescopic output end of the second cylinder 603 through the fifth rotating shaft 607. The side surface of the rotating rod 605 is fixedly connected to the fixed box 608. The grinding component 8 is fixedly installed on the fixed box 608 and deflects synchronously with the fixed box 608.

[0030] The grinding assembly 8 used in this device includes working components such as a built-in drive motor and a high-speed rotating grinding wheel. The grinding assembly 8 itself is a conventional structure in the art and will not be described in detail here. The grinding assembly 8 is fixedly connected to the fixed box 608. When the rotating rod 605 deflects around the fourth rotating shaft 604, the fixed box 608 and the grinding assembly 8 on it deflect as a whole, ensuring that the inclined cutting angle can be reliably transmitted to the working surface of the grinding wheel.

[0031] Before the grinding feed begins, the controller 12 controls the second cylinder 603 inside the fourth adjusting assembly 6 to operate. The extension or retraction of the second cylinder 603 pushes or pulls the fixing block 606 via the fifth rotating shaft 607, forcing the rotating rod 605 to deflect around the fourth rotating shaft 604 at a certain angle, thereby causing the fixed box 608 and the grinding assembly 8 fixedly mounted on it to tilt as a whole at a preset angle. Before the grinding assembly contacts the workpiece, the grinding disc has already formed an inclined cutting angle.

[0032] To address the issue of gray cast iron's weak impact resistance and susceptibility to chipping under concentrated loads, the grinding assembly 8, tilted and positioned, slowly cuts into the rough edge of the gray cast iron part at a small angle as the first cylinder 203 depresses downwards. As the grinding disc gradually enters the workpiece, the controller 12 controls the second cylinder 603 to slowly depressurize or reset, gradually restoring the rotating rod 605 and grinding assembly 8 from their tilted position to a horizontal state, thus completing the smooth grinding of the end face. This feeding method avoids the rigid impact and grinding vibration caused by the high-speed rotating grinding wheel's large-area instantaneous contact with the workpiece end face, protecting the integrity of the gray cast iron part's outer edge, reducing the scrap rate, and extending the service life of the internal consumables of the grinding assembly 8 by buffering the contact reaction force.

[0033] Please see the appendix Figure 2The upper surface of the operating platform 1 is fixedly connected to a second fixed plate 14 via a second support column 13, and the lower surface of the second fixed plate 14 is connected to a first connecting plate 302 via a telescopic rod 15. When the first adjusting component 2 drives the support component 3 to move up and down, the telescopic rod 15, constrained by the second fixed plate 14 and the second support column 13, provides auxiliary guiding support for the lifting and lowering action of the support component 3, preventing the support component 3 from tilting during the lifting and lowering process.

[0034] Please see the appendix Figure 1 The operating table 1 is equipped with a processing table 9 for placing gray cast iron parts, and a positioning column 10 is fixedly connected to the upper surface of the processing table 9. A controller 12 is fixedly connected to the front surface of the operating table 1 via a second connecting plate 11.

[0035] The machining table 9 and the positioning column 10 form the workpiece loading and centering reference. The operator places the gray cast iron main machining part with the pre-welded annular connector on the machining table 9, and aligns its center hole or reference surface with the positioning column 10 to fit it in, thereby achieving the centering of the workpiece's center with the rotation center of this grinding device, providing a reference for subsequent multi-point synchronous diameter changing grinding.

[0036] The controller 12 is equipped with a PLC control system. The drive motor 401, the first cylinder 203, the second cylinder 603, and the built-in drive motor of the grinding assembly 8 are all electrically connected to the controller 12. Working principle: When using this device, the operator places the gray cast iron workpiece to be ground on the processing table 9 and positions it at the center using the positioning pin 10. The controller 12 starts the drive motor 401, which drives the first rotating shaft 402 to rotate. Through the transmission cooperation of the first pulley 403, the conveyor belt 404, and the second pulley 405, the second rotating shaft 406 on the other side rotates synchronously. The synchronous rotation of the first rotating shaft 402 and the second rotating shaft 406 drives the rotating plates 501 fixedly connected to each other to rotate. During the rotation of the rotating plate 501, the groove wall of the guide groove 502 applies a thrust to the guide post 503. Since the slider 504 is constrained in the groove 702 inside the fixed rod 701 of the guide assembly 7 and can only slide radially, the circular motion of the rotating plate 501 is converted into the radial linear motion of the slider 504. The slider 504 drives the fourth adjusting assembly 6 and the grinding assembly 8 to synchronously contract inward or expand outward through the connecting rod 505, adjusting to the annular grinding radius position of the corresponding gray cast iron workpiece.

[0037] The controller 12 controls the operation of the second cylinder 603 inside the fourth adjustment assembly 6. The output end of the second cylinder 603 extends and retracts. Since the two ends of the second cylinder 603 are hinged through the third rotating shaft 602 and the fifth rotating shaft 607 respectively, its extension and retraction pushes and pulls the fixed block 606, forcing the rotating rod 605 to deflect around the fourth rotating shaft 604. The deflection of the rotating rod 605 causes the fixed box 608 and the grinding assembly 8 to tilt as a whole, forming an inclined cutting angle before the grinding assembly contacts the workpiece. The first cylinder 203 in the first adjustment assembly 2 is activated, pushing the support assembly 3 to move downward as a whole. During the downward movement, the telescopic rod 15, in conjunction with the second support column 13, plays a guiding role. As the support assembly 3 moves downward as a whole, the grinding assembly 8, in an inclined posture, slowly cuts into the outer end face of the gray cast iron workpiece at a small angle, avoiding the rigid impact caused by the instantaneous contact of the grinding wheel with the workpiece.

[0038] As the grinding disc gradually cuts into the workpiece, the second cylinder 603 slowly performs reverse pressure relief or reset adjustment, causing the rotating rod 605 and the grinding assembly 8 to gradually return from an inclined angle to a horizontal and flat state, achieving consistent grinding of the end faces of multiple connecting parts. After grinding is completed, the first cylinder 203 drives the entire structure to reset and rise.
