Description

Technical Field

[0001] This invention relates to the field of tire vulcanization mold processing equipment, specifically to a flipping tool and method for precision machining the end face reference surface of cast aluminum tread blocks. Background Technology

[0002] like Figure 7 As shown, the tread block is the core component of the tire mold, and its processing quality directly affects the tire's appearance and quality. Existing tread blocks are typically made of cast aluminum, and usually have internal holes at both ends. The symmetry and positional accuracy of its cavity curves are key aspects that need to be ensured during processing.

[0003] Specifically, the end face reference surface machining of cast aluminum patterned blocks is the first or second (after rough machining) finishing process in the entire patterned block machining process. By machining the end face of the cast aluminum patterned block (usually the back or bottom surface of the patterned block) into a high-precision plane, it serves as the process reference for all subsequent machining processes (such as milling, drilling, finishing, etc.). Therefore, the end face reference surface of cast aluminum patterned blocks has extremely high dimensional accuracy and geometric tolerance requirements.

[0004] Currently, the end face reference surface of cast aluminum patterned blocks is usually roughed using a vertical machining center or a large milling machine. Then, a three-jaw chuck with soft jaws, special fixtures, or pads and pressure plates on the worktable is used to align and initially fix the cast aluminum patterned blocks. This process requires a lot of manual operation, and a lot of time is spent on positioning and alignment. It is difficult to effectively guarantee the machining accuracy and quality. Furthermore, a lot of time needs to be spent on correction in subsequent processes, which seriously affects production efficiency.

[0005] Therefore, the development and design of a flipping tooling and method that can accurately and conveniently finish the end face reference surface of cast aluminum patterned blocks, meet the requirements of dimensional accuracy and geometric tolerance, provide fast and accurate positioning and alignment, and realize automatic processing is an urgent problem to be solved. Summary of the Invention

[0006] To address the problems existing in the prior art, this invention provides a flipping fixture and method for precision machining the end face reference surface of a cast aluminum patterned block. A stationary plate and a movable plate that can move towards or away from the stationary plate can be used to firmly position the inverted cast aluminum patterned block. A measuring component moves within a first plane to sequentially measure the cavity of the cast aluminum patterned block at multiple preset coordinate points. When the measurement data does not meet the accuracy requirements, a first driving component drives the flipping frame to rotate and adjust the position of the cast aluminum patterned block. The measuring component then measures the cavity of the cast aluminum patterned block again until the measurement data meets the accuracy requirements. This ensures that the cast aluminum patterned block is quickly and accurately positioned and aligned, thereby enabling accurate and convenient precision machining of the end face reference surface of the cast aluminum patterned block, ensuring compliance with dimensional accuracy and geometric tolerance requirements, and achieving automated machining.

[0016] As a preferred technical solution, in step S2, the clamping torque of the moving plate on the cast aluminum patterned block will not cause the cast aluminum patterned block to deform.

[0017] The beneficial effects of this invention are as follows: 1. The present invention provides a flipping fixture for the end face reference surface of a precision-machined cast aluminum patterned block. The flipping frame can rotate relative to the support base. Both the stationary plate and the moving plate are set on the flipping frame. When the cast aluminum patterned block is placed upside down on the flipping frame with both the stationary plate and the moving plate located inside the cavity of the cast aluminum patterned block, the moving plate moves away from the stationary plate to tighten the stationary plate. Then, the pressure plate presses down slowly on the cast aluminum patterned block from above, thus restricting the degree of freedom in the height direction. The measuring component moves in the first plane to measure the cavity of the cast aluminum patterned block at multiple preset coordinate positions in sequence. The first driving component drives the flipping frame to rotate and adjust the position of the cast aluminum patterned block until the measurement data of the measuring component meets the accuracy requirements, thereby achieving precise alignment of the cast aluminum patterned block, assisting the machine tool in precise machining, ensuring that the end face reference surface of the cast aluminum patterned block can be accurately and conveniently precision-machined, while meeting the requirements of dimensional accuracy and geometric tolerance, and significantly improving the machining quality of the cast aluminum patterned block.

[0019] 3. The flipping fixture for the reference surface of the end face of the precision-machined cast aluminum patterned block of the present invention has several support parts on the opposite sides of the stationary plate and the moving plate. When the cast aluminum patterned block is flipped over, the side edges of the cast aluminum patterned block are placed on the support parts. At the same time, a centering part is provided in the middle of the support parts, and two centering points are provided at the uppermost end of the centering part. When all the centering points on the two centering parts at both the stationary plate and the moving plate are in contact with the cast aluminum patterned block, the placement position of the cast aluminum patterned block along the moving direction of the moving plate can be accurately guaranteed.

[0020] 4. The flipping fixture for the end face reference surface of the precision-machined cast aluminum patterned block of the present invention has a locking component that can further lock the support base and the flipping frame, ensuring that the cast aluminum patterned block on the flipping frame is securely clamped, thereby ensuring the machining accuracy of the end face reference surface of the cast aluminum patterned block.

Detailed Implementation

[0025] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0026] Please refer to Figures 1-7 This invention provides an embodiment of a flipping fixture for precision machining of the end face reference surface of a cast aluminum patterned block, comprising a support base 1, which can be mounted on a machine tool; a flipping frame 2 disposed on the support base 1, the flipping frame 2 being able to rotate relative to the support base 1 around a first axis, the flipping frame 2 being connected to a first driving component 21 for driving its rotation, and when the cast aluminum patterned block 9 is mounted on the flipping frame 2, the cast aluminum patterned block 9 can rotate with the flipping frame 2; The stationary plate 3 is fixed on the flip frame 2, and the moving plate 4 is arranged opposite to the stationary plate 3. A slide rail and slider structure are provided between the moving plate 4 and the flip frame 2, so that the moving plate 4 can move in the direction of approaching or moving away from the stationary plate 3. The moving plate 4 is connected to a second drive component 41 that drives its movement. When the cast aluminum patterned block 9 is placed upside down (i.e. the cavity 93 of the cast aluminum patterned block 9 faces downward) on the flip frame 2 and both the stationary plate 3 and the moving plate 4 are located in the cavity 93 of the cast aluminum patterned block 9, the moving plate 4 can move away from the stationary plate 3 to support and position the stationary plate 3. The pressure plate 5 is located above the flip frame 2. The pressure plate 5 can move in the direction of approaching or moving away from the flip frame 2. The pressure plate 5 is connected to a third drive component 51 that drives its movement. When the cast aluminum patterned block 9 is placed on the flip frame 2, the pressure plate 5 presses on the cast aluminum patterned block 9 from above, further improving the positioning stability of the cast aluminum patterned block 9. The measuring component 6 is located between the support base 1 and the flip frame 2. The measuring component 6 is connected to a fourth drive component that can move it in the first plane. The measuring component 6 can move in the first plane to measure the cavity 93 of the cast aluminum patterned block 9 at multiple preset coordinate positions in sequence, obtain measurement data (i.e., the size data of the cavity 93 of the cast aluminum patterned block 9), and determine whether the installation of the cast aluminum patterned block 9 meets the accuracy requirements through the measurement data.

[0027] Further, please refer to Figures 1-6The present invention should also include a locking assembly, which includes a second tensioning cylinder 14. The cylinder body of the second tensioning cylinder 14 is fixed on the support base 1, and the piston rod of the second tensioning cylinder 14 is fixedly connected to the flipping frame 2. The second tensioning cylinder 14 is connected to a controller. When the installation of the cast aluminum patterned block 9 meets the accuracy requirements, the locking assembly can lock the support base 1 and the flipping frame 2, ensuring that the cast aluminum patterned block 9 on the flipping frame 2 is stably clamped, thereby ensuring the machining accuracy of the end face reference surface 91 of the cast aluminum patterned block 9. It should be noted that a buffer washer 15 can be provided between the piston rod of the second tensioning cylinder 14 and the flipping frame 2, which can further improve the locking effect. In order to ensure the locking effect, the number of second tensioning cylinders 14 can be multiple.

[0028] Furthermore, please refer to Figures 1-6 The flip frame 2 is provided with a guide sleeve 22. The third drive assembly 51 includes a guide rod 52, which passes through the guide sleeve 22. The pressure plate 5 is rotatably connected to the upper end of the guide rod 52. The piston rod of the pressing cylinder is connected to the lower end of the guide rod 52. Preferably, the pressure plate 5 can also be provided with a handle so that when the cast aluminum patterned block 9 is placed on the flip frame 2, the pressure plate 5 can be easily turned to one side to avoid interference.

[0029] It should be noted that the flip frame 2 is preferably made of cast iron, which has high stability and is not easily deformed. The flip frame 2 has a hollow structure in the middle to ensure that the measuring component 6 can measure the cavity 93 of the cast aluminum patterned block 9. The pressure plate 5 is preferably made of hard plastic.

[0030] In this embodiment, the present invention should also include a controller, which is connected to the first drive component 21, the second drive component 41, the third drive component 51, the measuring component 6, and the fourth drive component respectively. The controller can control the switching and working intensity of the first drive component 21, the second drive component 41, the third drive component 51, and the fourth drive component, and can receive the measurement information from the measuring component 6, thereby controlling the first drive component 21, the second drive component 41, the third drive component 51, and the fourth drive component to work in an orderly manner, so as to realize the automatic positioning, alignment, and clamping of the cast aluminum patterned block 9.

[0031] Specifically, the controller is preferably a PLC; the first drive component 21 is preferably a rotary drive motor; the second drive component 41 is preferably a first tensioning cylinder; the third drive component 51 is preferably a pressing cylinder; the measuring component 6 is preferably a laser probe, and the laser measurement method is not affected by the ribs and steel sheets inside the cavity 93 of the cast aluminum patterned block 9; in other embodiments, the controller can also be a machine tool system directly, the first drive component 21 can also be a hydraulic motor, the second drive component and the third drive component 51 can also be electric cylinders, and the measuring component 6 can also be a distance sensor.

[0032] Further, please refer to Figures 1-4 The fourth driving component includes a first linear guide rail 61, a first slider 62 that moves along the first linear guide rail 61, a second linear guide rail 63 that moves along the first slider 62, and a second slider 64 that moves along the second linear guide rail 63. The measuring component 6 is mounted on the second slider 64 and is located in the first plane. The extension direction of the first linear guide rail 61 is perpendicular to the extension direction of the second linear guide rail 63 and is parallel to the first plane. The first slider 62 and the second slider 64 cooperate with each other to drive the measuring component 6 to move to any position in the first plane, so as to realize the measurement of the cavity 93 of the cast aluminum patterned block 9 at multiple preset coordinate positions, ensuring the accuracy of the measurement data. Specifically, in order to ensure the stability and accuracy of the moving position of the measuring component 6, both the first linear guide rail 61 and the second linear guide rail 63 include two parallel linear guide rails.

[0033] In this embodiment, please refer to Figures 1-6 The support base 1 is provided with two opposing ribs 11. The bottom of the two ribs 11 is fixedly connected by the base plate 12. The flip frame 2 is located between the two ribs 11. The flip frame 2 and the two ribs 11 are rotatably connected by guide bearings 13, so that the flip frame 2 can rotate relative to the support base 1. The first axis is the axis of the guide bearing 13.

[0034] Further, please refer to Figures 1-6 The invention also includes two centering portions 7 corresponding to the stationary plate 3 and the moving plate 4, respectively. Several protruding support portions 8 are provided on the opposite sides of the stationary plate 3 and the moving plate 4, and these support portions 8 are symmetrically arranged based on the centering portions 7. Each centering portion 7 includes a centering block with two separately arranged centering points 71 at its top. These two centering points 71 are higher than the upper edges of the stationary plate 3 and the moving plate 4, i.e., the centering block is V-shaped. Furthermore, the moving direction of the moving plate 4 is perpendicular to the first axis. When the cavity 93 of the cast aluminum patterned block 9 is placed upside down on the flipping frame 2, the lower edge of the cast aluminum patterned block 9 abuts against the support portions 8, simultaneously... The two centering points 71 at the top of the centering part 7 abut against the arc-shaped surface of the cast aluminum patterned block 9, which can ensure that the placement position of the cast aluminum patterned block 9 along the moving direction of the moving plate 4 is accurate. The cast aluminum patterned block 9 can be aligned simply by swinging the first axis around the flipping frame 2. In other embodiments, the structure on the stationary plate 3 and the moving plate 4 used to support the cast aluminum patterned block 9 can also be of other forms to ensure that there are four or more parts that contact the cast aluminum patterned block 9, which can ensure that the placement position of the cast aluminum patterned block 9 on the flipping frame 2 is accurate. In addition, the centering block can also be of other shapes, as long as it has two protruding centering points 71 on its top.

[0035] It should be noted that the centering part 7 may also include an elastic element. The elastic element is vertically arranged, and the centering block is located at the upper end of the elastic element. The elastic element supports the centering block. When the centering block is subjected to pressure, it can move slightly in the vertical direction, i.e., towards or away from the flip frame 2, to achieve flexible centering of the centering block. In the actual assembly process, in order to ensure that the cast aluminum patterned block 9 abuts against the centering point 71 on the centering block when placed on the support part 8, the centering point 71 on the centering block can be slightly higher than its position after abutting against the cast aluminum patterned block 9. After abutting against the cast aluminum patterned block 9, it is more convenient and accurate to observe whether the two centering points 71 abut against the arc surface on the cast aluminum patterned block 9 at the same time, ensuring that the position of the cast aluminum patterned block 9 is accurate.

[0036] Specifically, please refer to Figures 1-6 The centering part 7 corresponding to the stationary plate 3 can be set on the flip frame 2 or the stationary plate 3, and the centering part 7 corresponding to the moving plate 4 is set on the moving plate 4. The two centering parts 7 are aligned with the positions of the stationary plate 3 and the moving plate 4 respectively, ensuring that the position of the cast aluminum patterned block 9 is accurate when it is placed upside down on the flip frame 2.

[0037] Further, please refer to Figures 1-6 Both the stationary plate 3 and the moving plate 4 are provided with two support parts 8, and the support parts 8 are preferably cylindrical pins. The cast aluminum patterned block 9 is in line contact with the cylindrical pins, which facilitates the adjustment of the position of the cast aluminum patterned block 9 and ensures that one side of the cast aluminum patterned block 9 is in contact with both cylindrical pins and two centering points 71 at the same time, thus ensuring the accurate placement of the cast aluminum patterned block 9. In other embodiments, the support parts 8 can also be other shapes, as long as they can stably support the cast aluminum patterned block 9.

[0038] Secondly, please refer to Figures 1-7 The present invention also provides a method for flipping the reference surface of the end face of a precision-machined cast aluminum patterned block, applied to the aforementioned fixture for flipping the reference surface of the end face of a precision-machined cast aluminum patterned block, comprising the following steps: S1: Adjust the distance between the moving plate 4 and the stationary plate 3 to be less than the distance between the two inner holes 92 of the cast aluminum patterned block 9. Place the cavity 93 of the cast aluminum patterned block 9 face down on the flip frame 2 and place it upside down on the moving plate 4 and the stationary plate 3. Both the moving plate 4 and the stationary plate 3 extend into the cavity 93 of the cast aluminum patterned block 9. Specifically, place the lower edge of the cast aluminum patterned block 9 on the protruding support part 8 and adjust the position of the cast aluminum patterned block 9 so that the arc-shaped feature surface on the cast aluminum patterned block 9 abuts against the two centering points 71 at the top of the centering part 7. This will accurately position the cast aluminum patterned block 9. S2: Operate the second drive component 41 to move the moving plate 4 away from the stationary plate 3 until the cast aluminum patterned block 9 is tightened; specifically, the moving plate 4 moves away from the stationary plate 3 until the two opposite sides of the moving plate 4 and the stationary plate 3 respectively abut against the cavity 93 surface of the cast aluminum patterned block 9, thereby tightening and positioning the cast aluminum patterned block 9; preferably, the shape of the two opposite sides of the moving plate 4 and the stationary plate 3 should match the shape of the corresponding position of the cavity 93 of the cast aluminum patterned block 9; furthermore, in order to prevent the cast aluminum patterned block 9 from being tightened and deformed, it is necessary to calculate the tightening torque of the moving plate 4 in advance to ensure that the cast aluminum patterned block 9 is positioned without deforming it; S3: Operate the third drive component 51 to press the cast aluminum patterned block 9 from above with the pressure plate 5; specifically, before the pressure plate 5 presses down, rotate the pressure plate 5 to the appropriate position. S4: The fourth drive component is operated to make the measuring component 6 measure the cavity 93 of the cast aluminum patterned block 9 at multiple preset coordinate positions in sequence, and obtain measurement data; specifically, multiple preset coordinate positions are stored in the controller in advance, and the controller controls the fourth drive component to make the measuring component 6 move to multiple preset coordinate positions in sequence; the measurement data obtained by the measuring component 6 is sent to the controller, and the controller has a data range that meets the accuracy requirements stored in advance; S5: Determine whether the measurement data meets the accuracy requirements; if the measurement data does not meet the accuracy requirements, operate the first drive component 21 to rotate the flip frame 2, adjust the position of the cast aluminum patterned block 9, and repeat step S4 until the measurement data meets the accuracy requirements; if the measurement data meets the accuracy requirements, the machining process of the end face reference surface 91 of the cast aluminum patterned block 9 can be performed; specifically, by comparing whether the measurement data falls within the pre-stored data range that meets the accuracy requirements, it can be determined whether the measurement data meets the accuracy requirements.

[0039] In addition, once the measurement data meets the accuracy requirements, the support base 1 and the flip frame 2 are locked together using the locking assembly to ensure that the cast aluminum patterned block 9 is securely clamped and all its degrees of freedom are restricted, thereby ensuring the machining accuracy of the end face reference surface 91 of the cast aluminum patterned block 9.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
