Description

Technical Field

[0001] This invention relates to the field of intake manifold end face milling technology, and more specifically to an intake manifold end face milling device. Background Technology

[0002] The intake manifold typically consists of a main pipe, multiple independent branch pipes, and connecting flanges at the ends of each branch pipe. Each flange face needs to fit against the mounting surface of the engine cylinder head, so the coplanarity requirement of multiple flange faces is high.

[0003] After long-term use, heat deformation, collision, or refurbishment, different branches of the intake manifold may bend or sag to varying degrees, resulting in height differences between the flange end faces. When processing such intake manifolds, existing milling equipment usually uses a uniform fixture to fix the main pipe and branch pipes, and then mills multiple flange end faces sequentially according to a preset feed rate. It is difficult to determine the actual height of each flange before processing, which can easily lead to insufficient removal of the high flange or excessive removal of the low flange, affecting the final coplanarity of multiple flange end faces. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides an intake manifold end face milling device, which can effectively solve the problem of height differences between multiple flange end faces caused by deformation of various branch pipes in the overhauled intake manifold.

The output end of the linear displacement device is provided with a movable seat. The fixing assembly and the fixed height detection assembly are both mounted on the movable seat. The fixed height detection assembly includes lifting detection structures corresponding to each of the multiple flanges. Each lifting detection structure is used to abut against the corresponding flange from bottom to top and detect the height of the corresponding flange. The two-dimensional drive device is used to drive the milling device to move in the horizontal and vertical directions, so that the milling cutter sequentially mills the end faces of the multiple flanges.

[0008] Preferably, the fixing component includes a mounting base fixedly installed on the upper end of the movable seat. The upper end of the mounting base is provided with a lower retaining ring and an upper retaining ring. One end of the intake manifold body is disposed between the lower retaining ring and the upper retaining ring. Both sides of the lower retaining ring and the upper retaining ring are detachably connected by locking members.

[0009] Preferably, a sliding seat is fixedly installed at the upper end of the upper retaining ring, a sliding strip is slidably installed inside the sliding seat, a horizontal groove is provided on the sliding strip, and a first fixing member is provided at the upper end of the sliding seat.

[0010] Preferably, one end of the sliding bar is provided with an L-shaped frame, the L-shaped frame has a vertical groove, one end of the sliding bar is provided with a second fixing member passing through the vertical groove, the second fixing member includes a screw and a nut threadedly connected to the screw; one end of the L-shaped frame is fixedly installed with a crossbar, and the crossbar has a plurality of first retaining rings spaced apart along its length to support the intake manifold body.

[0011] Preferably, the fixed height detection component includes a telescopic member disposed on one side of the mounting base and away from the lower retaining ring. The output end of the telescopic member passes through the mounting base and is connected to a vertical plate. The upper end surface of the mounting base is provided with a bottom slide rail located between the lower retaining ring and the vertical plate. The lower end of the vertical plate is slidably connected to the bottom slide rail. A connecting rod is fixedly installed on the upper end of the vertical plate. Multiple slots are formed on the connecting rod along its length.

[0012] Preferably, the lower end of the linkage is provided with a plurality of U-shaped connecting frames corresponding one-to-one with the slots, each U-shaped connecting frame is provided with a second retaining ring on one side, a movable plate is fixedly installed on one side of the vertical plate, each U-shaped connecting frame is provided with a sliding groove, a sliding seat is slidably installed in the sliding groove, and a fixing box is fixedly installed on the upper end of the sliding seat.

[0013] Preferably, a lifting plate is slidably installed inside the fixing box, and a limiting rod penetrating the lifting plate is provided inside the fixing box.

[0015] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0016] First, the initial height of each flange of the intake manifold body is detected by a fixed height detection component, and the milling cutter is driven by a two-dimensional drive device to perform differential milling on each flange end face in sequence. This removes more material from the high flange and less material from the low flange, so that multiple flange end faces are on the same processing plane. This avoids insufficient flange height caused by using a uniform feed rate and improves the end face processing accuracy of the overhauled intake manifold.

The lower retaining ring and the upper retaining ring fix the main pipe end, and the first retaining ring and the second retaining ring clamp each branch pipe from both sides. The rising retaining ring supports the lower end of the flange respectively. The slot and the rectangular retaining block cooperate to restrict the downward movement of the rising retaining ring and reduce the swing of the branch pipe during the milling process.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] The present invention will be further described below with reference to embodiments.

[0027] Example: Refer to Figures 1 to 5 An intake manifold end face milling device, comprising:

[0028] The system includes a base plate 1, an end milling assembly 2, a fixing assembly 4 for fixing the intake manifold body 3, and a fixed height detection assembly 5 for detecting the height of multiple flange ends of the intake manifold body 3. The upper end face of the base plate 1 is provided with a linear displacement device 201 and a two-dimensional drive device 202. The output end of the two-dimensional drive device 202 is provided with a milling device 203. The lower end of the milling device 203 is provided with a milling cutter 204 for milling the flange end faces. The output end of the linear displacement device 201 is provided with a moving seat 205. The fixing assembly 4 and the fixed height detection assembly 5 are both provided on the moving seat 205. The fixed height detection assembly 5 includes lifting detection structures corresponding to multiple flanges. Each lifting detection structure is used to abut against the corresponding flange from bottom to top and detect the height of the corresponding flange. The two-dimensional drive device 202 is used to drive the milling device 203 to move in the horizontal and vertical directions, so that the milling cutter 204 mills the end faces of multiple flanges in sequence.

[0029] Reference Figure 3 The fixing component 4 includes a mounting base 401 fixedly installed on the upper end of the movable base 205. The upper end of the mounting base 401 is provided with a lower retaining ring 402 and an upper retaining ring 403. One end of the intake manifold body 3 is located between the lower retaining ring 402 and the upper retaining ring 403. Both sides of the lower retaining ring 402 and the upper retaining ring 403 are detachably connected by locking members 404. The lower retaining ring 402 and the upper retaining ring 403 fix the main pipe end of the intake manifold body 3. The first retaining ring 413 and the second retaining ring 506 clamp each branch pipe from opposite sides. The rising retaining ring 518 supports from the lower end of the flange, forming a graded fixing of the main pipe end, branch pipes and flange. This can shorten the transmission distance of milling force and reduce the swing, torsion and local bending of individual branch pipes during milling.

[0030] Reference Figure 3 A sliding seat 405 is fixedly installed on the upper end of the upper retaining ring 403. A sliding strip 406 is slidably installed inside the sliding seat 405. A transverse groove 407 is provided on the sliding strip 406. A first fixing member 408 is provided on the upper end of the sliding seat 405. The first fixing member 408 includes a screw that passes through the transverse groove 407 and a nut that is threadedly connected to the screw, which is used to lock the position of the sliding strip 406 relative to the sliding seat 405.

[0031] Reference Figure 3 One end of the sliding bar 406 is provided with an L-shaped frame 409, and the L-shaped frame 409 is provided with a vertical groove 411. One end of the sliding bar 406 is provided with a second fixing member 410 passing through the vertical groove 411. The second fixing member 410 includes a screw and a nut threadedly connected to the screw. One end of the L-shaped frame 409 is fixedly installed with a crossbar 412. The crossbar 412 is provided with a plurality of first retaining rings 413 at intervals along its length for supporting the intake manifold body 3.

[0032] Reference Figures 4 to 5 The fixed height detection component 5 includes a telescopic member 501 located on one side of the mounting base 401 and away from the lower retaining ring 402. The output end of the telescopic member 501 passes through the mounting base 401 and is connected to a vertical plate 503. The upper end of the mounting base 401 is provided with a bottom slide rail 502 located between the lower retaining ring 402 and the vertical plate 503. The lower end of the vertical plate 503 is slidably connected to the bottom slide rail 502. A connecting rod 504 is fixedly installed on the upper end of the vertical plate 503. Multiple slots 507 are opened along the length of the connecting rod 504. The telescopic member 501 can first drive the fixed height detection component 5 to approach the intake manifold body 3, and then continue to drive the second retaining ring 506 to clamp the branch pipe after the flange height detection is completed. At the same time, the relative sliding of the slide block 510 and the slide groove 509 maintains the position of the rising retaining ring 518, so that the approach, detection, clamping and locking actions are completed continuously, reducing the number of independent drive mechanisms.

[0033] Reference Figures 4 to 5 The lower end of the linkage 504 is provided with multiple U-shaped connecting brackets 505 corresponding one-to-one with the slots 507. Each U-shaped connecting bracket 505 has a second retaining ring 506 on one side. A movable plate 508 is fixedly installed on one side of the vertical plate 503. Each U-shaped connecting bracket 505 has a sliding groove 509. A slide seat 510 is slidably installed in the sliding groove 509. A fixed box 511 is fixedly installed on the upper end of the slide seat 510. The inner diameter of the rising retaining ring 518 is larger than the inner diameter of the second retaining ring 506, so that the rising retaining ring 518 can move upward independently and detect the flange height before the second retaining ring 506 clamps the branch pipe. After the detection is completed, the second retaining ring 506 moves closer to the outer wall of the branch pipe to avoid interference between the detection action and the lateral clamping action.

[0034] Reference Figures 4 to 5 A lifting plate 512 is slidably installed inside the fixed box 511. A limiting rod 513 is provided inside the fixed box 511 that passes through the lifting plate 512. Springs 514 are fixedly installed at the upper and lower ends of the lifting plate 512 and outside the limiting rod 513. A pressure detection element 515 is provided at the upper end of the fixed box 511. The upper and lower ends of the springs 514 abut against the fixed box 511 and the pressure detection element 515, respectively. A linkage bar 516 is provided on one side of the lifting plate 512. A rectangular locking block 517 is provided at the lower end of the linkage bar 516. A rising retaining ring 518 is provided at the end of the linkage bar 516 away from the fixed box 511. The inner diameter of the rising retaining ring 518 is larger than the inner diameter of the second retaining ring 506.

[0035] Reference Figures 4 to 5 Multiple lifting components 519 are slidably arranged at intervals along the length of the upper end of the movable plate 508. The telescopic ends of each lifting component 519 pass through the corresponding slide groove 509 and are connected to the corresponding rising retaining ring 518. Each lifting component 519 is used to drive the corresponding rising retaining ring 518 to abut against the lower end of the flange of the intake manifold body 3. The contact state and height difference of the corresponding flange are detected by spring 514, limit rod 513 and pressure detection element 515 so that the end faces of multiple flanges can be machined according to different milling feed rates.

[0036] The working principle of this invention is as follows:

[0037] Based on the external dimensions of the intake manifold body 3 and the spacing between each branch pipe, the fixing assembly 4 is adjusted. The nut in the first fixing member 408 is loosened so that the sliding strip 406 can move laterally along the sliding seat 405. The horizontal groove 407 is used to avoid the screw of the first fixing member 408, thereby adjusting the horizontal position of the L-shaped bracket 409 and the crossbar 412 relative to the mounting base 401. After the horizontal position is adjusted, the first fixing member 408 is tightened to fix the sliding strip 406 on the sliding seat 405. Then the second fixing member 410 is loosened so that the L-shaped bracket 409 moves up and down relative to the sliding strip 406 by means of the vertical groove 411 to adjust the support height of the crossbar 412 and multiple first retaining rings 413. After each first retaining ring 413 can correspond to each branch pipe of the intake manifold body 3, the second fixing member 410 is tightened again, thereby completing the pre-adjustment of the fixing assembly 4.

[0038] When clamping the intake manifold body 3, first disassemble the locking piece 404 connecting the lower retaining ring 402 and the upper retaining ring 403, put the main pipe end of the intake manifold body 3 into the lower retaining ring 402, and let each branch pipe fall into the corresponding first retaining ring 413 on the crossbar 412. The lower retaining ring 402 is used to support the main pipe end of the intake manifold body 3. The upper retaining ring 403 closes with the lower retaining ring 402 from above the main pipe end. Then, the lower retaining ring 402 and the upper retaining ring 403 are connected by the locking pieces 404 on both sides, so that the main pipe end is fixed on the mounting base 401. Each first retaining ring 413 supports each branch pipe from below, so as to prevent each branch pipe from drooping or swinging due to its own weight when only the main pipe end is fixed. At this time, the intake manifold body 3 maintains its natural shape before clamping, and the original height difference of each flange end face will not be changed by forcibly flattening.

[0039] After the intake manifold body 3 is fixed, the telescopic component 501 begins to extend. The output end of the telescopic component 501 pushes the vertical plate 503 to move along the bottom slide rail 502 toward the intake manifold body 3. When the vertical plate 503 moves, it drives the connecting rod 504, multiple U-shaped connecting brackets 505, multiple second retaining rings 506 and the moving plate 508 to move synchronously, so that each second retaining ring 506 enters below the corresponding branch pipe and each rising retaining ring 518 is located below the corresponding flange. The bottom slide rail 502 restricts the movement direction of the vertical plate 503 to prevent the fixed height detection component 5 from deflecting when it approaches the intake manifold body 3. The multiple slots 507 on the connecting rod 504 correspond to the positions of the multiple U-shaped connecting brackets 505, leaving space for the installation and movement of each lifting detection structure.

[0040] When checking the height of each flange, each lifting component 519 extends from the same initial position. The telescopic end of the lifting component 519 moves upward, causing the corresponding rising retaining ring 518 to move closer to the lower end of the flange. Since the inner diameter of the rising retaining ring 518 is larger than the inner diameter of the second retaining ring 506, the rising retaining ring 518 can avoid the outer wall of the branch pipe when it rises and contact the lower end of the flange from below. Different branch pipes and flanges may be at different heights after overhaul. Therefore, when each rising retaining ring 518 contacts the corresponding flange, the actual extension stroke of the lifting component 519 is not the same: the flange at the lower position contacts the rising retaining ring 518 earlier, and the extension stroke of the corresponding lifting component 519 is smaller; the flange at the higher position contacts the rising retaining ring 518 later, and the extension stroke of the corresponding lifting component 519 is larger.

[0041] Before the rising retaining ring 518 contacts the flange, the extension action of the lifting component 519 is mainly used to drive the rising retaining ring 518 to rise. After the rising retaining ring 518 abuts the lower end of the flange, the flange blocks the continued rise of the rising retaining ring 518. The small extension movement of the lifting component 519 is transmitted to the lifting plate 512 through the rising retaining ring 518 and the linkage bar 516, causing the lifting plate 512 to move in the direction defined by the fixed box 511 and the limiting rod 513. When the lifting plate 512 moves, it drives the spring 514 to be compressed. The spring 514 transmits the contact force to the pressure detection element 515. The limiting rod 513 is used to limit the movement direction of the lifting plate 512 and prevent the lifting plate 512 from deflecting in the fixed box 511 after being subjected to force.

[0042] When the pressure detected by the pressure sensing element 515 reaches the preset contact pressure, it indicates that the corresponding rising retaining ring 518 has made stable contact with the lower end of the flange. At this time, the extension of the corresponding lifting member 519 is stopped, and the extension stroke of the lifting member 519 from the initial position to the current contact position is recorded. Each pressure sensing element 515 uses the same preset contact pressure. Therefore, the pressure sensing element 515 is mainly used to determine whether the rising retaining ring 518 has made contact with the flange. The extension stroke of each lifting member 519 when it reaches the contact state is used to reflect the height of the corresponding flange. By comparing the extension strokes of multiple lifting members 519, the relative height difference between multiple flanges can be obtained, avoiding the influence of different branch pipe stiffness on directly judging the flange height by the magnitude of the contact pressure.

[0043] After the height of each flange is detected, the pressure detection element 515 maintains the corresponding detection result, and each lifting component 519 stops extending upward, so that each rising retaining ring 518 is held at the lower end of the corresponding flange. At this time, the rising retaining ring 518 is blocked by the flange and cannot continue to move. The rising retaining ring 518 supports the lower end of the flange on the one hand, and keeps the extension position of the corresponding lifting component 519 unchanged on the other hand. Since the original heights of multiple flanges are different, the final height of each rising retaining ring 518 is also different, thus preserving the original height of each flange in its natural state and avoiding the change of the position of the branch pipe and flange after the detection.

[0044] After the rising retaining ring 518 completes the detection and abuts against the lower end of the flange, the telescopic component 501 extends for the second time, continuing to push the vertical plate 503 along the bottom slide rail 502 toward the intake manifold body 3. The vertical plate 503 drives multiple U-shaped connecting frames 505, the second retaining ring 506, and the moving plate 508 to move toward the intake manifold body 3 simultaneously through the connecting rod 504. Since the rising retaining ring 518 has abutted against the lower end of the flange and is restricted by the flange, when the fixed height detection component 5 continues to move, the lifting component 519 and its connected rising retaining ring 518 slide relative to the U-shaped connecting frame 505 under the guidance of the slide block 510 and the slide groove 509, so that the rising retaining ring 518 is kept at the lower end of the corresponding flange, while the second retaining ring 506 can continue to move toward the outer wall of the corresponding branch pipe.

[0045] As the telescopic component 501 continues to extend, each of the second retaining rings 506 contacts the outer wall of the corresponding branch pipe on one side, causing the second retaining ring 506 and the first retaining ring 413 to clamp the corresponding branch pipe from opposite sides. After the second retaining ring 506 contacts the outer wall of the branch pipe, the telescopic component 501 stops moving. At this time, the lower retaining ring 402 and the upper retaining ring 403 fix the main pipe end of the intake manifold body 3, the first retaining ring 413 and the second retaining ring 506 fix each independent branch pipe laterally, and the rising retaining ring 518 independently supports each flange from below, thereby restricting the overall movement of the intake manifold body 3, the lateral swing of the branch pipe, and the downward displacement of the flange. When the branch pipe of the intake manifold body 3 is connected to the outer wall, the linkage rod 504 moves synchronously with the vertical plate 503, so that the inner wall of the corresponding slot 507 on the linkage rod 504 gradually approaches the lower end of the rectangular locking block 517. As the telescopic member 501 continues to extend slightly, the inner wall of the slot 507 contacts the lower end of the rectangular locking block 517 and forms a squeeze, so that the rectangular locking block 517 is limited by the slot 507. Since the rectangular locking block 517 is connected to the rising locking ring 518 through the linkage bar 516, after the rectangular locking block 517 is limited by the slot 507, the downward movement of the linkage bar 516 and the rising locking ring 518 is simultaneously limited, thereby locking the rising locking ring 518 in the support position of the corresponding flange lower end.

[0046] After locking, the lower retaining ring 402 and the upper retaining ring 403 are used to fix the main pipe end of the intake manifold body 3, the first retaining ring 413 and the second retaining ring 506 are used to clamp each independent branch pipe, and the rising retaining ring 518 is used to support the lower end of the corresponding flange. The squeezing fit between the slot 507 and the rectangular retaining block 517 is used to prevent the rising retaining ring 518 from moving downward after being subjected to force. During the milling process, the downward force applied to the flange by the milling cutter 204 is transmitted sequentially to the rising retaining ring 518, the linkage bar 516 and the rectangular retaining block 517. The rectangular retaining block 517 is blocked by the slot 507, so that the rising retaining ring 518 maintains its original supporting height and avoids the spring 51. 4. When the pressure or the retraction of the lifting component 519 causes the flange to move downward, after the fixing is completed, the linear displacement device 201 drives the moving seat 205, the intake manifold body 3, the fixing component 4 and the fixed height detection component 5 to move together to the processing area of ​​the end face milling component 2. The two-dimensional drive device 202 drives the milling device 203 to move in the horizontal and vertical directions, so that the milling cutter 204 processes each flange end face in sequence. According to the extension stroke obtained by each lifting component 519 in the detection stage, the initial height of each flange is determined, and the milling cutter 204 uses the corresponding material removal amount for different flanges until the processed end faces of multiple flanges are on the same target plane.

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 of the technical features.
