Description

Technical Field

[0001] This invention relates to the field of enhanced grinding technology, and in particular to an adaptive enhanced grinding device for curved thin-walled parts and its method of use. Background Technology

[0002] Intensive grinding is a composite processing method for strengthening the surface of metallic materials to resist fatigue, corrosion, and wear. It utilizes a mixture of grinding powder, grinding fluid, and steel balls to accelerate the impact on the material surface, causing severe plastic deformation. This induces internal crystal defects to develop into dislocations, subgrain boundaries, or grain boundaries, resulting in grain refinement of the surface material and increasing the surface hardness. At the same time, residual compressive stress is introduced into the material surface, inhibiting the initiation and development of surface fatigue cracks and improving the fatigue life of the material.

[0003] For curved thin-walled components such as aircraft wing panels, engine blades, and automobile body shells, the working environment is unique. They not only need to overcome severe fatigue, wear, and corrosion problems, but also need to maintain good performance for a long period. Under these conditions, intensified grinding is a better method for surface finishing of curved thin-walled components. A mixture of grinding powder, grinding fluid, and steel balls can ensure plastic deformation and generate residual compressive stress on the surface of thin-walled components while minimizing the impact on the component's shape. Furthermore, intensified grinding is low-cost and has minimal environmental pollution, making it ideal for the physical surface finishing of curved thin-walled components.

[0004] However, existing reinforcing abrasive equipment does not have the function of processing curved thin-walled parts, and since the shapes of curved thin-walled parts are not necessarily the same, the reinforcing abrasive processing device for curved thin-walled parts also needs to have the ability to adapt to the workpiece. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptive strengthening grinding device and its method for use on curved thin-walled parts, which enables the strengthening grinding equipment to clamp curved thin-walled parts, improves the stability and efficiency of the processing, and improves the quality of strengthening grinding.

[0006] According to one objective of the present invention, an adaptive strengthening grinding device for curved thin-walled parts is provided, comprising an adaptive clamping mechanism fixed inside a strengthening grinding chamber. The adaptive clamping mechanism includes a main lifting platform, a tilting mechanism, and four auxiliary lifting platforms. The main lifting platform and the auxiliary lifting platforms are all fixed on a fixed frame. The four auxiliary lifting platforms are located around the main lifting platform. The tilting mechanism is respectively provided between the main lifting platform and the auxiliary lifting platforms. A pressure sensor is provided on the tilting mechanism. An infrared sensor is provided at each end of the pressure sensor. A suction cup is installed at the top of the pressure sensor.

[0007] Furthermore, the main lifting platform includes a central stepper motor, a central lead screw, and a central slider. The central stepper motor is fixed to the bottom center of the fixed frame. The output shaft of the central stepper motor is connected to the central lead screw through a second coupling. The central slider is threadedly connected to the central lead screw. A fixing nut is fixed to the top of the central lead screw.

[0008] Furthermore, the auxiliary lifting platform includes an edge stepper motor, a first lead screw, a first slider, and a slide rail. The edge stepper motor is fixed at the four corners of the mounting bracket via a motor mounting frame. The output shaft of the edge stepper motor is connected to the first lead screw via a first coupling. The top and bottom of the first lead screw are fixed to the motor mounting bracket via a lower support and an upper support, respectively. A slide rail is fixed to the inner side of the motor mounting bracket. The slide rail is bolted to one side of the first lead screw. A first slider is threaded onto the first lead screw. One side of the first slider engages with the slide rail, and the first slider can slide up and down along the slide rail.

[0009] Furthermore, the tilting mechanism includes a connecting rod, a second lead screw, a servo mounting bracket, a servo, and a drive frame. The connecting rod is hinged to each of the four edges of the central slider, and the other ends of the four connecting rods are respectively hinged to the corresponding first sliders. The second lead screw is threaded to the connecting rod, and the top end of the second lead screw is connected to the servo mounting bracket. The servo is fixed on the servo mounting bracket, and the drive frame is mounted on the servo. The pressure sensor and the infrared sensor are mounted on the upper end of the drive frame.

[0010] Furthermore, the four edges of the central slider are respectively hinged to the connecting rods via the first hinge axis, and the other ends of the four connecting rods are respectively hinged to the corresponding first sliders via the second hinge axis.

[0011] Furthermore, the second lead screw is threadedly connected to the screw hole at the center of the connecting rod, and a nut is provided on the second lead screw.

[0012] Furthermore, an auxiliary fixing mechanism is fixed to the outer side of the adaptive clamping mechanism. The auxiliary fixing mechanism includes a support frame, front and rear slide rails, front and rear sliders, lifting slide rails, and lifting sliders. The fixing frame is fixedly connected to the upper end of the support frame. The front and rear slide rails are provided on the inner side of the support frame. The front and rear sliders are provided inside the front and rear slide rails. The front and rear sliders are configured to cooperate with the front and rear slide rails. The lifting slide rails are fixedly installed on the front and rear sliders. The lifting sliders are slidably disposed inside the lifting slide rails. The lifting sliders are configured to cooperate with the lifting slide rails.

[0013] Furthermore, the lifting slider and the lifting rail can be fixed together by bolts.

[0014] Furthermore, the lifting slider is hinged to a connecting bracket, and a rubber sleeve is connected to the connecting bracket.

[0015] According to another objective of the present invention, the present invention provides a method of using an adaptive strengthening grinding apparatus for curved thin-walled parts, comprising the following steps:

[0016] S1, place the curved thin-walled part above the adaptive clamping mechanism. At this time, the four pressure sensors detect whether there is a heavy object above the suction cup. If the value of one of the pressure sensors is greater than 0, where Q represents the value detected by the pressure sensor, it proves that the curved thin-walled part has been placed above the adaptive clamping mechanism. At this time, the infrared sensor is activated to detect and obtain eight data points detected by the infrared sensor.

[0017] S2, for the suction cup with a pressure sensor value greater than 0, meaning the suction cup has already contacted the sample, the control formula for the rotation angle of the servo motor at that end is as follows to ensure that the suction cup can fully adsorb the sample:

[0018]

[0019] Where x1 and x2 are the distance values ​​between the sample and the two infrared sensors located on one of the pressure sensors, and s is the horizontal distance between the two infrared sensors;

[0020] S3, for the suction cup where the pressure sensor reading is 0, i.e., the suction cup is not in contact with the sample, it is necessary to raise the suction cup. The adjustment height of the auxiliary lifting platform at this end satisfies the following relationship:

[0021]

[0022] Where L0 is the length of the connecting rod, L1 is the length of the second lead screw in the tilting mechanism from the connecting rod to the suction cup, and w is the pitch of the first lead screw of the auxiliary lifting platform.

[0023] S4. After all four suction cups have successfully adsorbed the sample, the pressure sensor value is monitored at all times. If the value is zero, it may be that the workpiece has fallen off and needs to be readjusted to prevent accidents.

[0024] S5, the pressure sensor receives a start signal. When the signal is received, the infrared sensor starts to collect data. Based on the information from the pressure sensor and the infrared sensor, the suction cups are adjusted so that all four ends of the suction cups contact the sample and are fully adsorbed. The pressure sensor is monitored.

[0025] When a curved thin-walled part is placed above the processing equipment, the pressure sensor receives a signal, activating the infrared sensor. Based on the data from the infrared and pressure sensors, the angle of the tilting mechanism is adjusted to ensure the suction cup makes full contact with the workpiece surface. This device enables the enhanced grinding equipment to clamp curved thin-walled parts and adapts to the workpiece shape, significantly saving time and improving production efficiency. Furthermore, the pressure sensor continuously monitors the clamping effect to prevent accidents. The device as a whole can be smoothly adjusted in posture, has a strong load-bearing capacity, and stable driving effect. Both the main and auxiliary lifting platforms are adjustable, allowing the distance between the workpiece and the nozzle to be adjusted simultaneously during enhanced grinding, thus improving the overall quality of the enhanced grinding of curved thin-walled parts.

[0041] Each connecting rod 17 has a screw hole at its center. The second lead rod 16 is threadedly connected to the screw hole at the center of the connecting rod 17. The second lead rod 16 is provided with a nut 19, which is threadedly connected to the lower end of the second lead rod 16. The second lead rod 16 can be fixed by the nut 19.

A connecting bracket 33 is hinged to the lifting slider 32 by bolts, and a rubber sleeve 34 is connected to the connecting bracket 33 by bolts.

[0045] When performing enhanced grinding on curved thin-walled parts, a pressure sensor below the suction cup receives a pressure signal. At this time, eight infrared sensors start collecting data. The suction cup angle is adjusted for the suction cup end where the pressure sensor value is non-zero, and the suction cup with zero pressure sensor value is raised to contact the workpiece and the suction cup angle is adjusted. After the four suction cups successfully clamp the workpiece, the pressure sensor will continuously monitor the working status of the workpiece to ensure that if the workpiece suddenly falls off, the clamping is immediately readjusted. At the same time, the auxiliary fixing frame is adjusted to stabilize the workpiece and prevent the workpiece from falling off accidentally.

[0046] A method of using an adaptive strengthening grinding apparatus for curved thin-walled parts includes the following steps:

[0047] 1. Place the curved thin-walled part above the strengthening grinding processing device. At this time, four pressure sensors detect whether there is a heavy object above the suction cup. If the value of one pressure sensor is greater than 0, i.e. Q>0, where Q represents the value detected by the pressure sensor, it proves that the curved thin-walled part has been placed above the processing device. At this time, the infrared sensor in the processing device is activated to detect and obtain eight data points detected by the infrared sensor.

[0048] 2. For the suction cup end where the pressure sensor value is greater than 0, meaning the suction cup has already contacted the sample, the rotation angle control formula for the servo motor at that end is as follows to ensure the suction cup can fully adsorb the sample:

[0049]

[0050] Where x1 and x2 are the distance values ​​between the sample and the two infrared sensors located on one of the pressure sensors, and s is the horizontal distance between the two infrared sensors;

[0051] 3. For the suction cup end where the pressure sensor reading is 0, i.e., the suction cup is not in contact with the sample, it is necessary to raise the suction cup. The adjustment height of the auxiliary lifting platform at this end should satisfy the following relationship:

[0052] Calculate the value of h, and then use the conversion formula to obtain the rotation angle of the edge stepper motor at that location. After the suction cup at one end contacts the sample, adjust the suction cup's posture, i.e., the formula.

[0053] Where L0 is the length of the connecting rod, L1 is the length of the second lead screw in the tilting mechanism from the connecting rod to the suction cup, and w is the pitch of the first lead screw of the auxiliary lifting platform.

[0054] 4. After all four suction cups have successfully adsorbed the sample, adjust the auxiliary fixing frame to stabilize the sample and prevent it from falling accidentally. At the same time, monitor the pressure sensor value at all times. If the value is zero, it may be that the workpiece has fallen off and needs to be readjusted to prevent accidents.

[0055] 5. Based on the above formula, the pressure sensor receives the start signal. When the signal is received, the infrared sensor starts to collect data. According to the information from the pressure sensor and the infrared sensor, the suction cups are adjusted so that all four suction cups contact the sample and fully adsorb it. Finally, the auxiliary fixing frame is adjusted and the pressure sensor is monitored to prevent accidental drop.

[0056] This invention uses a pressure sensor to detect whether a workpiece is placed, and then uses an infrared sensor to adjust the suction cup posture. For the end with the pressure reading, only the tilt angle of the servo motor needs to be adjusted. For the side without pressure values, the formula still needs to be solved. The h value in and using and The rotation angles of the stepper motor and the servo motor are obtained. At this point, all four suction cups are in full contact with the workpiece, and the suction cup adsorption function is activated. During the enhanced grinding process, the four Q values ​​are monitored to ensure that Q > 0. If a suction cup falls off, it must be readjusted to prevent accidents.

[0057] When a curved thin-walled part is placed above the processing equipment, the pressure sensor receives a signal, activating the infrared sensor. Based on the data from the infrared and pressure sensors, the angle of the servo motor is adjusted to ensure the suction cup makes full contact with the workpiece surface. This device enables the grinding equipment to clamp curved thin-walled parts, adapts to the shape of the workpiece, greatly saves time, improves production efficiency, and the pressure sensor continuously monitors the clamping effect to prevent accidents.

[0058] The device of this invention can be smoothly adjusted in posture, has strong load-bearing capacity, and stable driving effect. Moreover, both the main and auxiliary lifting platforms are adjustable, allowing the distance between the workpiece and the nozzle to be adjusted while the workpiece is being reinforced and ground, thereby improving the overall quality of the reinforcement and grinding of curved thin-walled parts.

[0059] All parts not described in this invention are the same as or can be implemented using existing technologies. This invention enables the strengthening grinding equipment to clamp curved thin-walled parts, improves the stability and efficiency of the processing, and can also improve the quality of strengthening grinding to a certain extent.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
