Description

Technical Field

[0001] This invention belongs to the field of composite material machining technology, and particularly relates to a positioning and adjustment device for machining composite material compartments and its usage method. Background Technology

[0002] Before machining composite products, the equipment needs to accurately locate the origin on the workpiece. This is typically done using specialized tools (such as a coordinate measuring machine) to determine the workpiece's reference plane and position. After determining the origin, the machine tool's coordinate system needs to be aligned with the workpiece's coordinate system to ensure the accuracy and consistency of the tool's movement.

[0003] like Figure 1 The existing technical solutions shown mostly use manual addition of shims. The alignment of the coordinate system is adjusted by repeatedly adding or removing shims 2 of various thicknesses between the workpiece 1 and the support. In the operation of adding or removing shims 2, it usually requires two or more people to lift the workpiece before adding them. If the adjustment is not appropriate, it is necessary to repeat the operation many times.

[0004] Disadvantages of existing technology:

[0005] 1. The workpiece needs to be lifted manually to place the shim. This requires two or more people to operate, which is complicated, cannot be adjusted quickly, and is inefficient.

[0006] 2. Because the thickness of the various shims used is fixed, they can be used individually or in combination, and cannot be infinitely adjusted, often resulting in insufficient or excessive adjustment, requiring readjustment.

[0007] 3. The adjustment and fixing of the workpiece are all done manually. The adjustment amount and tightness are based on experience and feeling, which may cause certain deformation and damage to the workpiece. Especially in the processing of large composite materials or hollow materials, excessive deformation may cause irreversible inert deformation and scrap the workpiece.

[0008] 4. During the adjustment, some supporting components failed to provide support, causing workpiece displacement or disturbance during processing, resulting in low processing accuracy or even workpiece scrap. Summary of the Invention

[0009] The purpose of this invention is to provide a positioning and adjustment device and its usage method for machining composite material compartments, so as to solve the technical problems of large workload, high labor consumption, and inability to adjust steplessly before machining.

[0010] To solve the above-mentioned technical problems, the specific technical solution of the composite material compartment machining positioning and adjustment device and its usage method of the present invention is as follows:

[0011] A composite material compartment section machining positioning and adjustment device includes an L-shaped base, a linear guide rail mounted on the base, a flange slider movably mounted on the linear guide rail, and a triangular slider fixedly mounted on the flange slider; it also includes a drive device and a transmission device, the drive device driving the slider to move on the linear guide rail via the transmission device, a through hole being formed on the vertical end face of the slider, and a through hole being formed on the vertical section of the L-shaped base, the through hole and the through hole being interconnected; it also includes a lead screw nut, a lead screw, and a fixing seat, the lead screw nut being mounted on the vertical side of the through hole, and a fixing seat for supporting the lead screw being mounted on the outside of the through hole, the lead screw passing through the through hole, the fixing seat, the through hole, and the fixing seat, and the drive device being mounted on the outer end of the lead screw. A locking handle is installed in the horizontal and vertical directions of the perforation on the L-shaped base to fix the lead screw in place. A nylon pad is installed on the inclined surface of the slider. The upper surface of the nylon pad is smooth and abuts against the surface of the workpiece. A stop is fixed to the top of the vertical section of the L-shaped base by bolts. The driving device is a handwheel or a drive motor. A cavity is opened on the inclined surface of the triangular slider. There is a fixing hole on the side wall of the cavity. A pressure sensor and an adapter ball head connected to the pressure sensor are installed in the cavity. The end of the pressure sensor protruding from the inclined surface of the slider is connected to the nylon pad. The nylon pad is used to support the workpiece and transmit the pressure of the workpiece. The adapter ball head is fixed to the inner wall of the cavity through a pressure signal plug that passes through the fixing hole. The pressure signal plug is connected to a signal line and connected to the controller.

[0012] Furthermore, the pressure sensor transmits the pressure signal through the signal line connected to the pressure signal output plug via an adapter ball joint, and an alarm device is connected to the controller.

[0013] Furthermore, the adjustment device is set on the base plate and can be used individually, in pairs, or in multiples. The base plate is mounted on a device with horizontal adjustment capabilities.

[0014] This invention also provides a method for using a machining positioning and adjustment device for composite material compartment sections.

[0015] S1, place the composite compartment to be processed on the base plate, and use a tensioner to initially tighten the fastening strap (15) to initially fasten the workpiece to be processed;

[0016] S2, Use a coordinate measuring machine to determine the workpiece reference surface and position; after determining the origin of the workpiece to be machined;

[0017] S3, through the positioning adjustment device, makes stepless adjustment to realize the rotation of the workpiece along the axis and the adjustment of its height, aligning the coordinate system of the machine tool with the coordinate system of the workpiece to ensure the accuracy and consistency of the tool movement;

[0018] S4, when there is no pressure or the pressure is lower than the set lower limit, a warning prompt will be given; when the pressure exceeds the upper limit alarm value, an alarm prompt will be given.

[0019] When the workpiece coordinates are inconsistent with the machine tool coordinates, adjust the adjustment mechanism. The operation steps for adjusting the positioning adjustment device are as follows: Start the drive device to drive the lead screw to rotate simultaneously. The rotation of the lead screw drives the lead screw nut to move. The lead screw nut drives the slider to move along the linear guide rail, and at the same time drives the nylon pad to move. The movement of the nylon pad will lift, lower or rotate the product; realize the rotation of the workpiece along the axis and the adjustment of its height; after the adjustment is completed, lock the locking handle.

[0020] Furthermore, before adjusting the manual adjustment device, upper and lower pressure alarm values ​​are set. When the fastening belt is tightened or the adjustment device is adjusted, the pressure applied to the pressure sensor by the workpiece is detected. When the pressure applied to the pressure sensor by the workpiece reaches the preset pressure value, an alarm is triggered, further operation is stopped, the adjustment device is adjusted in the opposite direction or the fastening belt is loosened, and adjustment is performed again.

[0021] A warning message is given when the workpiece does not exert pressure on the pressure sensor of the adjustment device or the pressure is below the lower limit. The corresponding adjustment device is then adjusted to ensure that the adjustment device provides sufficient support for the workpiece.

[0022] Furthermore, using a controller adjustment device, the over-limit setting of the pressure sensor is linked with the operation of the drive motor. Before adjustment, upper and lower limit pressure alarm values ​​are set. When the drive motor is started to adjust the adjustment device, the pressure applied to the pressure sensor by the workpiece is detected. When the pressure applied to the pressure sensor by the workpiece reaches the preset pressure value, an alarm is triggered, and the operation in that direction is stopped. The drive motor automatically reverses the adjustment device to release the pressure. The operator can then loosen the fastening belt or readjust the adjustment device.

[0023] A warning is given when the workpiece does not exert pressure on the pressure sensor of the adjustment device or the pressure is below the lower limit. The drive motor is then activated to adjust the corresponding adjustment device so that the adjustment device can provide sufficient support for the workpiece.

[0024] The composite material compartment machining positioning and adjustment device and its usage method of the present invention have the following advantages:

[0025] 1. A single person can adjust the workpiece, saving manpower and improving efficiency.

[0026] 2. Due to the use of a lead screw and inclined plane structure, the elevation and angle of the workpiece can be continuously adjusted steplessly.

[0027] 3. A pressure sensor is used to detect the pressure between the workpiece and the adjustment mechanism during adjustment and fixing operations. When the preset pressure value is reached, an alarm is triggered and the motorized adjustment mechanism stops running and reverses one level to release the pressure, preventing prolonged or excessive pressure on the workpiece and protecting it.

[0028] 4. Because a pressure sensor is installed, an alarm will be issued if the workpiece does not exert pressure on the adjustment device. The corresponding adjustment device will then be adjusted to ensure that the adjustment device supports the workpiece, preventing displacement or disturbance of the workpiece during processing and improving delivery accuracy.

[0039] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0040] In addition, numerous specific details are provided in the following detailed embodiments to better illustrate this application.

[0041] Those skilled in the art will understand that this application can be practiced even without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0042] To better understand the purpose, structure, function, and application of this invention, the following detailed description, in conjunction with the accompanying drawings, provides an explanation of a composite material compartment machining positioning and adjustment device and its usage method.

[0043] A composite material compartment machining positioning and adjustment device includes an L-shaped base 14, a linear guide rail 7 mounted on the base, a flange slider 6 movably mounted on the linear guide rail 7, and a triangular slider 4 fixedly mounted on the flange slider 6. The linear guide rail 7 mounted on the base allows the slider 4 to move smoothly on the flange slider 6.

[0044] The vertical end face of the slider 4 has a fixing nut 13 for the lead screw 10 and a through hole 19 for the lead screw 10 to pass through. The vertical section of the L-shaped base 14 has a through hole 21 for the lead screw 10 to pass through. A fixing seat 11 for supporting the lead screw 10 is installed on the outside of the through hole 21. A drive device for driving the lead screw is installed on the lead screw 10. The drive device is a handwheel 12 that can drive the lead screw 10 to rotate.

[0045] The drive device rotates the lead screw 10, and the lead screw nut 13 converts the rotation of the lead screw into the horizontal movement of the lead screw nut 13, which drives the slider 4 to move smoothly on the flange slider 6.

[0046] The lead screw nut 13 and the slider 4, and the flange slider 6 and the slider 4 are connected by screws or bolts.

[0047] A nylon pad 5 can also be provided on the inclined surface of the slider 4; the surface of the nylon pad 5 is smooth, and it slides on the workpiece surface as the slider 4 moves. The nylon pad 5 can better protect the workpiece surface from scratches.

[0048] A locking handle 17 is provided in the horizontal and vertical directions of the through hole 21 on the L-shaped base. The locking handle 17 passes through the threaded hole that is perpendicular to the through hole 21 to fix the lead screw 10 in place, so as to prevent the lead screw 10 from rotating due to pressure or shaking and to maintain the stability of the adjustment device.

[0049] A stop block 3 is fixed to the top of the vertical section of the L-shaped base 14 by bolts to limit the position of the workpiece and prevent the workpiece from falling off the processing table.

[0050] In practical applications, the adjustment device of the present invention can be used individually or in pairs.

[0051] For example, rotating the handwheel 12 drives the lead screw to rotate, and the lead screw nut 13 fixed on the slider 4 converts the rotational motion of the lead screw into horizontal movement, causing the slider 4 to move horizontally.

[0052] The adjustment state of a single adjusting device movement, such as Figure 4 As shown, when the triangular slider 4 moves towards the opposite end along direction a, it moves the nylon pad 5 along with it. Since the nylon pad 5 has a smooth surface, it will slide on the surface of the workpiece 1, moving to the bottom of the workpiece 1 or closer to the opposite end, thereby lifting the workpiece 1. Due to the unilateral movement, the opposite end remains stationary, and the workpiece will rotate. The direction of rotation is the direction of the supporting force exerted on the workpiece 1 by the inclined surface of the triangular slider 4, as shown... Figure 4 The direction R is shown. When the triangular slider 4 moves away from the opposite end (in the opposite direction to direction a), the workpiece will also rotate in the opposite direction to direction R.

[0053] Adjustment method when used in pairs, such as Figure 5 As shown, when the two triangular sliders 4, which are positioned opposite each other, move closer to each other, the sliders 4 of the adjusting device, which are positioned opposite each other, move in directions a and b respectively, causing the nylon pad 5 to move together. Since the nylon pad 5 has a smooth surface, it will slide on the surface of the workpiece and move to the bottom of the workpiece 1 or a position closer to the opposite end, thereby lifting the workpiece. When the workpiece is lifted to the same height on both sides, the workpiece is vertically lifted and moves in the Z direction.

[0054] When the workpiece being adjusted moves away from each other due to the movement of the two triangular sliders 4, the sliders 4 of the adjusting device move in opposite directions a and b, respectively, causing the nylon pad 5 to move together. Since the nylon pad 5 has a smooth surface, it will slide on the workpiece surface and move to the outside of the workpiece 1 or to a position further away from the opposite end, thereby reducing the workpiece elevation. When the workpiece elevation is reduced equally on both sides, the workpiece is vertically lifted and moves in the opposite direction of Z.

[0055] When the workpieces on both sides are lifted to different elevations, workpiece 1 will not only move in the Z direction, but also rotate. The rotation direction is from the side that is lifted more to the side that is lifted less.

[0056] When the workpiece elevations on both sides are inconsistent, workpiece 1 will not only move in the opposite Z direction, but will also rotate. The rotation direction is from the side with less elevation reduction to the side with more elevation reduction.

[0057] To enable more precise and rapid adjustments during workpiece machining, four adjustment devices can be installed at the four corners of the base plate 18. The base plate 18 is then mounted on an XY adjustment device (not shown in the figure) capable of horizontal X and Y direction adjustment, allowing for workpiece adjustment in the horizontal X and Y directions. When rotating and adjusting the elevation of the workpiece, the initial positioning point of workpiece 1 may shift horizontally. This can be corrected using the XY adjustment device, eliminating the need for further adjustments to the machine tool.

[0058] On large equipment that processes long workpieces, adjustment devices can be evenly arranged in the middle position along the length of the base plate 18 to better support the workpiece and adjust it more stably.

[0059] Furthermore, a horizontal rotation device can be added to the XY adjustment device, which has X and Y direction adjustment capabilities, to achieve the adjustment required for horizontal rotation.

[0060] The XY adjustment device can be a general-purpose machine tool XY worktable or a cross adjustment slide.

[0061] The horizontal rotation device can be a rotary table commonly used in machining.

[0062] Here is an application scenario for processing relatively long workpieces, such as Figure 3 As shown:

[0063] The base plate 18 is mounted on the XY worktable of the machine tool. Four adjustment devices are set at the four corners of the base plate 18, and one adjustment device is arranged on each side at the middle position along the length of the base plate 18.

[0064] In use, first place the composite material compartment to be processed on the base plate 18, use the tensioner 16 to initially tighten the fastening strap 15 to initially secure the processed product, and use a coordinate measuring machine to determine the workpiece reference surface and position; after determining the origin of the processed workpiece, adjust it through the 6 sets of stepless adjustment mechanisms of the machining positioning adjustment device to realize the rotation of the processed workpiece along the axis and the adjustment of its height, and align the coordinate system of the machine tool with the coordinate system of the workpiece to ensure the accuracy and consistency of the tool movement.

[0065] Operating steps of the positioning adjustment device: After the workpiece and base are fixed with a certain elasticity using a fastening band 15, the coordinates of the workpiece are measured by a coordinate measuring machine. If the coordinates of the workpiece are inconsistent with the coordinates of the machine tool, the stepless adjustment mechanism is adjusted. First, rotate the locking handle counterclockwise and rotate the handwheel 12 clockwise. The handwheel 12 drives the lead screw 10 to rotate simultaneously. The rotation of the lead screw 10 drives the lead screw nut 13 to move inward. The lead screw nut 13 drives the slider 4 to move inward along the linear guide rail 7, and at the same time drives the nylon pad 5 to move inward. Since the nylon pad is in contact with the product at a certain angle, the inward movement of the nylon pad will lift the product. This device is equipped with 6 adjustment mechanisms, which can realize the axial rotation and height adjustment of the workpiece. After adjustment, lock the locking handle 17.

[0066] In a further improvement, handwheel 12 is replaced with a drive motor that can rotate in both directions. The drive motor is connected to the controller, which makes it convenient for the operator to operate. The operator no longer needs to walk to each handwheel to make adjustments. Instead, the operator can adjust each adjustment device from the operating end, observe and grasp the degree and progress of the adjustment as a whole, further reducing the intensity of operation and increasing the adjustment accuracy.

[0067] In some application scenarios, three adjustment devices can be arranged in a triangle to achieve the same rotation and height adjustment of the workpiece 1.

[0068] In a further improvement, a cavity 22 is formed on the inclined surface of the triangular slider 4. A fixing hole 23 is located on the side wall of the cavity. A pressure sensor 8 and an adapter ball head 9 connected to the pressure sensor 8 are installed in the cavity. The end of the pressure sensor 8 extends out of the inclined surface of the slider 4 and connects to a nylon pad 5. The nylon pad 5 supports the workpiece and transmits the workpiece pressure. The adapter ball head 9 is fixed to the inner wall of the cavity 22 by a pressure signal plug 20 passing through the fixing hole 23. The pressure signal plug 20 is connected to a signal line, which is then connected to the controller.

[0069] Pressure sensor 8 transmits the pressure signal through the adapter ball joint 9 and the signal line connected to the pressure signal output plug 20. An alarm device is connected to the controller; it provides a warning when there is no pressure or the pressure is below the set lower limit, and an alarm when the pressure exceeds the upper limit.

[0070] During manual adjustment, an upper limit pressure alarm value is set according to the material and structure of the workpiece. When the fastening band 15 is tightened or the adjustment device is adjusted, the pressure applied to the pressure sensor by the workpiece is detected. When the pressure applied to the pressure sensor by the workpiece reaches the preset pressure value, an alarm is triggered to remind the operator to stop further operation. The adjustment device can be reversed or the fastening band 15 can be loosened for readjustment.

[0071] Because a pressure sensor is installed, a warning will be given if the workpiece does not exert pressure on the sensor or if the pressure is below the lower limit. The corresponding adjustment device will then be adjusted to ensure that the adjustment device provides sufficient support for the workpiece. This avoids the risk of workpiece displacement or disturbance during processing due to a lack of support on one side or at one point when there is no pressure sensor, which could lead to reduced processing accuracy or even scrap.

[0072] When using a controller-controlled drive motor, the pressure sensor's over-limit setting is linked to the motor's operation. Upon triggering an alarm for excessive pressure, the drive unit stops operating and retracts to a base position, releasing pressure to prevent prolonged or excessive pressure on the workpiece, thus protecting it. In cases of no pressure or excessively low pressure, a warning prompts the operator to adjust the regulating device appropriately to support the workpiece being processed.

[0073] From a practical point of view, the present invention has the following advantages:

[0074] 1. A single person can adjust the workpiece, saving manpower and improving efficiency.

[0075] 2. Due to the use of a lead screw and inclined plane structure, the elevation and angle of the workpiece can be continuously adjusted steplessly.

[0076] 3. A pressure sensor is used to detect the pressure between the workpiece and the adjustment mechanism during adjustment and fixing operations. When the preset pressure value is reached, an alarm is triggered and the motorized adjustment mechanism stops running and reverses one level to release the pressure, preventing prolonged or excessive pressure on the workpiece and protecting it.

[0077] 4. Because a pressure sensor is installed, an alarm will be issued if the workpiece does not exert pressure on the adjustment device. The corresponding adjustment device will then be adjusted to ensure that the adjustment device supports the workpiece, preventing displacement or disturbance of the workpiece during processing and improving delivery accuracy.

[0078] It is understood that the present invention has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of the present invention.
