Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, specifically to a grinding equipment for the surface of castings after forming. Background Technology

[0002] In modern manufacturing, casting is a crucial process, especially in the automotive, machinery, and electronics industries. The surface precision and quality of castings such as clutch pressure plates directly affect product performance and lifespan. Traditional casting surface grinding typically relies on manual operation, requiring workers to manually adjust the position of the workpiece and grinding tools. Due to variations in operating environments and worker skill levels, this method presents significant challenges in ensuring machining accuracy and stability, often failing to meet the required high-precision standards.

[0003] Existing surface grinding equipment for castings generally suffers from several problems. First, traditional equipment is inefficient during operation. Workers need to constantly manually adjust the position of the clutch pressure plate or the angle of the grinding tools, and the precision of manual operation is limited by the operator's experience, easily leading to uneven grinding, or even excessive or insufficient wear. Second, the precision of existing equipment often fails to meet high processing standards, especially when high precision and uniformity are required; manual operation struggles to ensure consistent results. Furthermore, operating traditional equipment presents certain safety hazards, particularly during grinding, where worker contact with the grinding tools increases the risk of accidents. On the other hand, existing grinding equipment often lacks sufficient flexibility; some lack pressure control during the grinding process, potentially leading to over-grinding or uneven grinding, affecting the final processing result. These problems severely impact the automation level of the production line, increase production costs, and reduce production efficiency. Summary of the Invention

[0004] To overcome the above-mentioned defects, the present invention provides a surface grinding device for castings after forming. It solves the technical problems that existing grinding devices are mostly operated manually, which is limited by the operator's experience and is prone to uneven grinding, or even excessive or insufficient grinding. In addition, existing grinding devices often lack sufficient flexibility, and some existing devices lack pressure control during the grinding process, which may lead to excessive or uneven grinding and affect the final processing effect.

Compared with traditional manual operation, the automation level of the equipment is greatly improved, which can significantly shorten the grinding time and improve production efficiency. The use of precision-controlled grinding components and pressure sensors can ensure stable pressure during the grinding process and avoid excessive or insufficient wear during the grinding process, thereby achieving a uniform grinding effect. By precisely controlling the grinding pressure, the high quality and precision of the clutch pressure plate surface are guaranteed, which can meet the processing standards with high precision requirements.

[0020] (2) In this invention, the limiting component can adapt to clutch pressure plates with different inner diameters, ensuring that clutch pressure plates of different specifications can be stably fixed and effectively ground. This feature enables the equipment to meet different processing needs, improves the equipment's versatility and flexibility. Through automated operation and precise control, this invention reduces the contact between workers and grinding tools, reducing safety hazards during worker operation. In addition, the equipment uses a pressure monitoring system during the grinding process to ensure that the grinding head does not excessively contact the workpiece, avoiding unnecessary accidents and further improving the safety of the working environment.

[0021] (3) In this invention, the deflection component allows the grinding component to adjust its angle flexibly, thereby enabling the outer wall and corners of the clutch pressure plate to be fully ground, ensuring that there are no dead angles in the grinding process.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0033] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product.

[0037] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] like Figures 1-2 As shown, it illustrates a surface grinding device for castings after forming, according to an embodiment of the present invention, comprising:

[0039] Base plate 1 is fixed to the corresponding workbench by bolts. A translation component 2 is fixed to the front and back direction of the top wall of base plate 1.

[0040] Mounting bracket 3 is installed on the top of translation component 2. A limiting component 4 for fixing the clutch pressure plate is rotatably installed on one side of the top of mounting bracket 3, and a driving component 5 for driving the limiting component 4 to rotate is installed on the other side of the top of mounting bracket 3.

[0041] The deflection assembly 7 is fixed to the top wall of the base plate 1 by two symmetrically arranged brackets 6. The deflection assembly 7 is equipped with a grinding assembly 8. The deflection assembly 7 is used to drive the grinding assembly 8 to deflect and achieve all-round grinding of the outer edge of the clutch pressure plate. The grinding assembly 8 is used to grind the outer edge of the clutch pressure plate and has a pressure control function.

[0042] Mounting holes 9 for bolts are provided at the corners of the base plate 1.

[0043] In this embodiment, the mounting holes 9 on the base plate 1, combined with bolts, allow the device to be easily fixed on the workbench at the corresponding position, ensuring stability during use. The translation component 2 enables the mounting frame 3 to move back and forth, thereby moving the limiting component 4 back and forth, facilitating the installation of the clutch pressure plate to be processed onto the limiting component 4. Simultaneously, it allows the fixed clutch pressure plate to be moved below the grinding component 8 for grinding. The limiting component 4 easily fixes the clutch pressure plate and can accommodate clutch pressure plates of different inner diameters. The driving component 5 drives the limiting component 4 to rotate, thus rotating the clutch pressure plate. This, in conjunction with the grinding component 8, allows for all-around grinding of the outer edge of the clutch pressure plate. The deflection component 7 can deflect the grinding component 8, enabling grinding of the outer wall and corners of the clutch pressure plate, achieving all-around grinding of the outer edge without the need for manual adjustment of the clutch pressure plate or grinding component 8, making operation simple and convenient. The grinding component 8 is designed to prevent excessive grinding of the clutch pressure plate during the grinding operation, thus ensuring the grinding effect of the clutch pressure plate.

[0044] like Figure 3 As shown, a translation component 2 in another embodiment of the present invention is illustrated. The translation component 2 includes two symmetrically arranged mounting seats 21, both of which are fixed to the top wall of the base plate 1. A lead screw 22 is rotatably mounted between the middle of the two mounting seats 21. A motor 24 for driving the lead screw 22 is fixed to the outer wall of one of the mounting seats 21. A matching movable seat 23 is screwed onto the lead screw 22. The movable seat 23 is fixed to the bottom wall of the mounting frame 3. Two guide shafts 25 are fixed between the two mounting seats 21. The guide shafts 25 slide through the side wall of the movable seat 23.

[0045] Two guide shafts 25 are symmetrically arranged with the lead screw 22 as the axis. The first motor 24 is a stepper motor or a servo motor. The power shaft of the first motor 24 passes through the corresponding mounting base 21 through the bearing and is fixedly connected to one end of the lead screw 22.

[0046] In this embodiment, the translation component 2 can drive the mounting bracket 3 to move back and forth, thereby driving the limiting component 4 to move back and forth, facilitating the installation of the clutch pressure plate to be processed onto the limiting component 4. Simultaneously, it can move the fixed clutch pressure plate below the grinding component 8 for grinding operations. Initially, the movable seat 23 is at the foremost position, allowing the operator to easily install the clutch pressure plate onto the limiting component 4. After the clutch pressure plate is installed, the first motor 24 is activated, driving the lead screw 22 to rotate. The lead screw 22 then moves the movable seat 23 rearward along the guide shaft 25 until the clutch pressure plate reaches the grinding position. The first motor 24 is a stepper motor or a servo motor, enabling the lead screw 22 to rotate in both directions.

[0047] like Figures 4-5 As shown, it illustrates a limiting component 4 and a driving component 5 in another embodiment of the present invention. The limiting component 4 includes a mounting cylinder 41, which is rotatably mounted on one side of the top of the mounting frame 3. A baffle 42 is fixed to the outer wall of the mounting cylinder 41. A screw 43 is rotatably mounted inside the mounting cylinder 41. A screw block 44 is screwed onto the screw 43. Several connecting rods 45 are symmetrically rotatably mounted on the outer wall of the screw block 44. A movable rod 46 is rotatably mounted on the other end of each connecting rod 45. One end of the screw 43 passes through the side wall of the mounting cylinder 41 through a bearing and is fixed with a knob 47.

[0048] The side wall of the mounting cylinder 41 is symmetrically provided with several mounting slots 10. The movable rod 46 is installed in the corresponding mounting slot 10, and one end of the movable rod 46 is rotatably installed between the inner walls of the mounting slot 10.

[0049] The drive assembly 5 includes a support plate 51, which is fixed to the side wall of the mounting frame 3. A second motor 52 is fixed to the top wall of the support plate 51. A drive gear 53 is fixed to the output end of the second motor 52. The drive gear 53 is meshed with a driven gear 54. One end of the mounting cylinder 41 passes through the side wall of the mounting frame 3 through a bearing and is fixedly connected to the axial position of the driven gear 54.

[0050] In this embodiment, the limiting component 4 can easily fix the clutch pressure plate and can adapt to clutch pressure plates with different inner diameters. At the same time, the driving component 5 drives the limiting component 4 to rotate, thereby driving the clutch pressure plate to rotate. In conjunction with the grinding component 8, the outer edge of the clutch pressure plate is ground in all directions.

[0051] When it is necessary to fix the clutch pressure plate to be ground onto the limiting assembly 4, firstly, the clutch pressure plate is placed on the mounting sleeve 41, and one side of the clutch pressure plate is attached to the baffle 42. Then, the knob 47 is turned, which drives the screw 43 to rotate. During the rotation of the screw 43, the screw block 44 is moved away from the baffle 42. During the movement of the screw block 44, the movable rod 46 is pushed outward of the mounting through groove 10 through the connecting rod 45. At this time, the outer wall of the movable rod 46 will press against the inner wall of the clutch pressure plate and press the clutch pressure plate towards the baffle 42 until the knob 47 can no longer be turned. At this time, the fixing of the clutch pressure plate is completed.

[0052] When grinding is required on the fixed clutch pressure plate, the drive assembly 5 is activated. The second motor 52 in the drive assembly 5 drives the drive gear 53 to rotate. The drive gear 53, through the driven gear 54, drives the mounting cylinder 41 to rotate, which in turn drives the clutch pressure plate. This, in conjunction with the grinding assembly 8, performs a comprehensive grinding operation on the outer edge of the clutch pressure plate. To ensure that the mounting cylinder 41 does not rotate during the rotation of the knob 47, the second motor 52 can be a motor with a self-locking function.

[0053] like Figures 6-8 As shown, a deflection assembly 7 and a grinding assembly 8 are illustrated in another embodiment of the present invention. The deflection assembly 7 includes two symmetrically arranged connecting plates 71, which are fixed on corresponding brackets 6. An arc-shaped guide rail 72 is fixed between the front ends of the two connecting plates 71, and an arc-shaped rack 73 is fixed between the rear ends of the two connecting plates 71. The arc-shaped guide rail 72 and the arc-shaped rack 73 are concentrically arranged. A vertical plate 74 is installed between the arc-shaped guide rail 72 and the arc-shaped rack 73. Four limiting rollers 75 that cooperate with the arc-shaped guide rail 72 are rotatably installed on the front wall of the vertical plate 74. A mounting plate 76 is fixed on the rear wall of the vertical plate 74. A third motor 77 is fixed on the top wall of the mounting plate 76. A drive gear 78 is fixed on the power shaft of the third motor 77. The drive gear 78 meshes with the arc-shaped rack 73. The third motor 77 is a stepper motor or a servo motor and has a self-locking function.

[0054] The grinding assembly 8 includes two symmetrically arranged electric push rods 81, which are fixed to the top wall of the mounting plate 76. The bottom movable ends of the two electric push rods 81 slide through the mounting plate 76 and are fixedly connected to the same horizontal plate 82. The bottom wall of the horizontal plate 82 is fixed with a mounting sleeve 83. A motor base 84 is slidably installed inside the mounting sleeve 83. The bottom end of the motor base 84 slides through the bottom of the mounting sleeve 83 and is fixed with a fourth motor 86. A grinding head 87 is detachably fixed on the power shaft at the bottom of the fourth motor 86. A pressure sensor 85 is fixed on the bottom wall of the horizontal plate 82 at the position corresponding to the motor base 84.

[0055] It also includes a controller, which is signal-connected to pressure sensor 85 and electric actuator 81.

[0056] In this embodiment, the deflection component 7 can deflect the grinding component 8, thereby enabling grinding operations on the outer wall and corners of the clutch pressure plate. This achieves all-around grinding of the outer edge of the clutch pressure plate without the need for manual adjustment of the clutch pressure plate or the grinding component 8, making operation simple and convenient. The grinding component 8 also prevents over-grinding of the clutch pressure plate during the grinding process, ensuring the grinding effect.

[0057] In its normal state, the deflection assembly 7 is located at the center of the arc-shaped guide rail 72. At this time, the grinding head 87 at the bottom of the grinding assembly 8 is in a horizontal state, which can grind the outer wall of the clutch pressure plate. When it is necessary to grind the outer corner of the clutch pressure plate, the No. 3 motor 77 is controlled to work. The No. 3 motor 77 drives the drive gear 78 to rotate. The drive gear 78, in conjunction with the arc-shaped rack 73, drives the grinding assembly 8 to deflect along the arc-shaped guide rail 72, thereby causing the grinding head 87 at the bottom of the grinding assembly 8 to shift by an angle, which can realize the grinding operation on the outer edge corner of the clutch pressure plate.

[0058] When the grinding assembly 8 is working, the fourth motor 86 is first turned on, which drives the grinding head 87 to rotate. Then, the electric push rod 81 is extended. During the extension of the electric push rod 81, the grinding head 87 moves down until it is in contact with the outer wall of the clutch pressure plate for grinding. At this time, the pressure sensor 85 can detect the pressure of the motor seat 84 on the horizontal plate 82. The pressure range of the pressure sensor 85 is set by the controller to ensure that the pressure of the motor seat 84 on the horizontal plate 82 is always kept within the preset range during the extension and retraction of the electric push rod 81. This can prevent the electric push rod 81 from extending too much and causing the grinding head 87 to grind the clutch pressure plate excessively, and it can also prevent the grinding head 87 from making poor contact with the grinding position, resulting in poor grinding effect.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
