Description

Technical Field

[0001] The present invention relates to the technical field of grinding machines, and in particular to an interactive curved surface forming numerically controlled grinding machine. Background Art

[0002] A grinding machine is a machine tool that grinds the surface of a workpiece using the periphery of a high-speed rotating grinding wheel. By the relative movement between the grinding wheel and the workpiece, the material on the surface of the workpiece is removed to achieve the required dimensional accuracy and surface finish. It is an important tool commonly used for precision machining in the field of mechanical processing.

[0003] Chinese Patent with publication number CN116494096A discloses an interactive curved surface forming numerically controlled grinding machine. A double workbench is provided in a vertical and horizontal forming numerically controlled grinding machine. The workbench support plate is connected to a hydraulic system, and the workbench is connected to a lead screw drive structure. Thus, hydraulic high-speed drive and servo slow positioning can be adopted, which can reduce the machining auxiliary time, better ensure the efficiency and accuracy of positioning, and better meet the high-precision machining requirements.

[0004] Although the above patent ensures the efficiency and accuracy of positioning through the dual drive of hydraulic pressure and servo, on the one hand, the double workbench, hydraulic drive, servo drive, and the electromagnetic locking devices for positioning of each double workbench are all stacked together. When a certain component is damaged, it is difficult to quickly remove it, increasing the maintenance difficulty.

[0005] And when machining heavier workpieces, compared with hydraulic cylinder drive, the servo drive system often has to bear a greater load. This means that in order to meet the machining requirements of workpieces of a certain weight, the servo drive system must be equipped with a higher-power motor and related components. In this way, not only does it increase the complexity and technical difficulty of the equipment, but also significantly raises the overall equipment cost. Summary of the Invention

[0006] The purpose of the present invention is to provide an interactive curved surface forming numerically controlled grinding machine, which effectively solves the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions.

[0008] An interactive curved surface forming CNC grinding machine includes a front bed base and a rear bed base. A workbench is slidably mounted on the upper surface of the front bed base. A double-rod hydraulic cylinder is mounted on the lower surface of the workbench. Fixed seats are mounted on the outer surfaces of both sides in the length direction of the front bed base, and the two telescopic ends of the double-rod hydraulic cylinder are respectively connected to the two fixed seats. A base is slidably mounted on the upper surface of the inclined guide rail of the rear bed base through a servo X-axis driving mechanism. A column base is mounted on the upper surface of the base. A lifting seat is mounted inside the column base through a servo Z-axis driving mechanism. A power mechanism is mounted on the bottom of the lifting seat through a servo Y-axis driving mechanism. A grinding head is mounted on the output end of the power mechanism, and a cover plate is arranged outside the grinding head.

[0009] Preferably, a lower liquid tank opening is formed on one side of the surface of the workbench close to the rear bed base. A liquid guide groove is arranged on the upper surface of the front bed base close to the rear bed base, and the liquid guide groove is arranged directly below the lower liquid tank opening. A liquid discharge groove opening is formed on the side wall of the liquid guide groove facing the rear bed base, and a water tank is arranged on the side surface of the rear bed base corresponding to the liquid discharge groove opening.

[0010] Preferably, an X-direction guide rail is mounted on the upper surface of the rear bed base, and the base is slidably mounted on the X-direction guide rail. Hook plates are mounted on both sides of the bottom of the base.

[0011] Preferably, the X-direction guide rail is of an inclined structure with the side close to the front bed base being high and the side far from the front bed base being low. The bottom of the base is of an inclined structure matching the X-direction guide rail, and the upper surface of the base is of a horizontal structure.

[0012] Preferably, a first electromagnetic locking device is mounted on the outer surface of the base, and a second electromagnetic locking device is mounted inside the front bed base.

[0013] Preferably, Z-direction slide rails are arranged on the inner wall of the column base, and the lifting seat is slidably connected to the Z-direction slide rails. Y-direction slide rails are arranged on the lower surface of the lifting seat, and the power mechanism is slidably connected to the Y-direction slide rails.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) In the present invention, the workbench and the base are respectively driven by a double-rod hydraulic cylinder and a servo X-axis driving mechanism, which can not only ensure the positioning efficiency and positioning accuracy during processing, but also avoid the complexity of the superposition structure. It can be quickly removed when a failure occurs, reducing the maintenance difficulty. The movement of the workpiece is driven by the double-rod hydraulic cylinder, while the servo X-axis driving mechanism is only used to drive the column base. This power distribution method can give full play to the advantages of the two driving methods, achieving a perfect combination of high efficiency and precision. Therefore, it is more suitable for processing large-weight workpieces, reducing the complexity and technical difficulty of the equipment, and also reducing the overall equipment cost, with high economy. And the interactive double X-axis direction movement can better achieve the purpose of digital forming processing. Description of the Drawings

Detailed implementation manners

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0017] As Figures 1 to 5 shown, an interactive curved surface forming CNC grinding machine includes a front bed base 100, a rear bed base 101, a workbench 102, a double-rod hydraulic cylinder 103, a fixed seat 104, a servo X-axis drive mechanism 105, a base 106, a column base 107, a servo Z-axis drive mechanism 108, a lifting seat 109, a servo Y-axis drive mechanism 110, a power mechanism 111, a cover plate 112, a lower liquid tank opening 200, a liquid guide groove 201, a liquid discharge groove opening 202, an X-direction guide rail 300, a hook plate 301, a first electromagnetic locking device 400, a second electromagnetic locking device 401, a Z-direction slide rail 500, and a Y-direction slide rail 501.

[0018] In the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more; the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] As Figures 1 to 5 shown, a workbench 102 is slidably mounted on the upper surface of the front bed base 100. A double-rod hydraulic cylinder 103 is mounted on the lower surface of the workbench 102. Fixed seats 104 are mounted on the outer surfaces on both sides in the length direction of the front bed base 100. The two telescopic ends of the double-rod hydraulic cylinder 103 are respectively connected to the two fixed seats 104. By driving the workbench 102 and the base 106 through the double-rod hydraulic cylinder 103 and the servo X-axis driving mechanism 105 respectively, not only can the positioning efficiency and positioning accuracy during processing be ensured, but also the complexity of the superimposed structure is avoided, the maintenance difficulty is reduced, and it is more suitable for processing large-weight workpieces.

[0021] A base 106 is slidably mounted on the upper surface of the inclined guide rail of the rear bed base 101 through a servo X-axis driving mechanism 105. A column base 107 is mounted on the upper surface of the base 106. A lifting seat 109 is mounted inside the column base 107 through a servo Z-axis driving mechanism 108. A power mechanism 111 is mounted on the bottom of the lifting seat 109 through a servo Y-axis driving mechanism 110. A grinding head is mounted on the output end of the power mechanism 111. A cover plate 112 is arranged outside the grinding head. The grinding head can be driven to move in the Z-axis direction through the servo Z-axis driving mechanism 108. Through the servo Y-axis driving mechanism 110, the grinding head can be driven to move in the Y-axis direction. Cooperating with the servo X-axis driving mechanism 105 to drive the grinding head to move in the X-axis direction, the purpose of adjusting the grinding head in three dimensions is achieved. And cooperating with the double-rod hydraulic cylinder 103 to drive the workbench 102 to move quickly in the X-axis direction, a faster positioning efficiency and better positioning accuracy are achieved, and higher-quality products can be processed.

[0022] On one side of the surface of the workbench 102 close to the rear bed base 101, a lower liquid tank opening 200 is provided. On one side of the upper surface of the front bed base 100 close to the rear bed base 101, a liquid guide groove 201 is provided, and the liquid guide groove 201 is arranged directly below the lower liquid tank opening 200. On one side wall of the liquid guide groove 201 facing the rear bed base 101, a liquid discharge groove opening 202 is provided. A water tank is arranged on the side surface of the rear bed base 101 corresponding to the liquid discharge groove opening 202. This equipment is also equipped with a grinding fluid spraying mechanism (not shown in the figure). During the grinding process, the sprayed grinding fluid can enter the liquid guide groove 201 through the lower liquid tank opening 200 and then flow out into the water tank through the liquid discharge groove opening 202, so as to realize the recycling of the grinding fluid. And a filter screen (not shown in the figure) is equipped in the water tank (not shown in the figure), which can intercept the metal chips in the grinding fluid. This is not only beneficial to the recycling of metal chips, but also avoids the situation of the spraying pipeline being blocked by metal chips.

[0023] As Figures 2 to 4 shown, an X-direction guide rail 300 is installed on the upper surface of the rear bed base 101, and the base 106 is slidably installed on the X-direction guide rail 300. Hook plates 301 are installed on both sides of the bottom of the base 106. The X-direction guide rail 300 provides accurate and stable movement guidance for the base 106 and improves the smoothness during the movement process. And through the setting of the hook plates 301, the base 106 can be firmly hooked on the X-direction guide rail 300 to avoid derailment and improve safety. The X-direction guide rail 300 is of an inclined structure with a higher side close to the front bed base 100 and a lower side far from the front bed base 100. The bottom of the base 106 is of an inclined structure matching the X-direction guide rail 300, and the upper surface of the base 106 is of a horizontal structure. Through the setting of the inclined structure, under the action of gravity, the base 106 can generate a force to slide obliquely downward, and this force can make the inner wall of the higher side of the base 106 and the hook plate 301 on the higher side tightly abut against the X-direction guide rail 300, so as to compensate for the accuracy influence brought by the assembly tolerance and further improve the machining accuracy.

[0024] The outer surface of the base 106 is equipped with a first electromagnetic locking device 400, and the second electromagnetic locking device 401 is installed inside the front bed base 100. The first electromagnetic locking device 400 is installed on the base 106 and can move synchronously with it. Therefore, the base 106 can be locked at any position on the X-axis guide rail 300. When the workbench 102 moves to the outermost positions on both sides, the second electromagnetic locking device 401 is still below it, so it can play a locking role. The inner wall of the column base 107 is provided with a Z-axis slide rail 500, and the lifting base 109 is slidably connected to the Z-axis slide rail 500. The lower surface of the lifting base 109 is provided with a Y-axis slide rail 501, and the power mechanism 111 is slidably connected to the Y-axis slide rail 501. By providing the Z-axis slide rail 500, the accuracy of the lifting base 109 moving in the Z-axis direction can be improved. By providing the Y-axis slide rail 501, the accuracy of the power mechanism 111 moving in the Y-axis direction can be improved. Combining with the moving accuracy of the column base 107 in the X-axis direction, the machining accuracy of the grinding head for the product can be guaranteed.

[0025] The specific working process and working principle of this device are as follows.

[0026] During use, first place the workpiece to be processed on the workbench 102 and fix it. Then, the workbench 102 can drive the workpiece to quickly move along the X-axis for rough positioning. Next, lock it with the second electromagnetic locking device 401. Then, drive the grinding head slowly and precisely by the servo X-axis drive mechanism 105. After locking the position of the base 106 with the first electromagnetic locking device 400, the grinding head can be driven to move in the Y-axis and Z-axis directions by the cooperation of the servo Z-axis drive mechanism 108 and the column base 107 to achieve the purpose of grinding the workpiece. The movement of the workpiece is driven by the double-rod hydraulic cylinder 103, and the servo X-axis drive mechanism 105 is only used to drive the column base 107. This power distribution method can give full play to the advantages of the two drive methods, achieve the perfect combination of high efficiency and precision, and thus be more suitable for processing large-weight workpieces, reducing the complexity and technical difficulty of the equipment, and also reducing the overall equipment cost, with high economy. Moreover, the interactive double X-axis direction movement can better achieve the purpose of digital forming processing.

[0027] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of the rights of the present invention. Therefore, the modifications, equivalent changes, improvements, etc. made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
