Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing equipment, specifically a clutch pressure cap drilling and forming equipment. Background Technology

[0002] The clutch pressure cover is a core component of the clutch, such as... Figure 11 As shown, the clutch connects the engine and the transmission, is responsible for transmitting power and controlling the engagement and disengagement of the clutch. The cover surface usually has a ring of diaphragm spring mounting holes, which are used to fix the diaphragm spring and ensure that it is evenly stressed. The dimensional accuracy and edge quality of these holes directly affect the reliability and service life of the clutch.

[0003] Diaphragm spring mounting holes are usually first processed by punching for rapid initial machining. However, since the punching process is prone to producing burrs or dimensional deviations, subsequent drilling is still required for finishing to improve the accuracy of the mounting holes. Currently, multi-hole CNC drilling machines are mainly used to drill the mounting holes of diaphragm springs.

[0004] However, when using a multi-hole CNC drilling machine to drill the diaphragm spring mounting hole, there is no stable support for the lower edge of the diaphragm spring mounting hole. As the drill bit passes through the pressure cap from top to bottom, the diaphragm spring mounting hole is easily deformed by the drill bit, resulting in burrs or cracks on the edge of the mounting hole, which reduces the processing quality. In addition, the fixture of the multi-hole CNC drilling machine cannot be adjusted in a flexible and quick manner, making it impossible to quickly and accurately align the mounting hole on the pressure cap with the drill bit, affecting the batch processing efficiency. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a clutch cover drilling and forming processing equipment, including an operating table, on which a drilling assembly is slidably arranged in the vertical direction, and an anti-deformation mechanism for supporting the drilling position of the cover is also provided on the operating table. The equipment also includes a cover locking mechanism for clamping and fixing the cover.

[0006] The anti-deformation mechanism includes a support plate fixedly installed on the upper part of the operating table. Several hole-aligning moving parts are equally spaced along the circumference of the upper part of the support plate and slide radially thereon. Several L-shaped hole-side supports are provided on the side of the hole-aligning moving parts near the axis of the support plate through a hole diameter adjustment component. The hole-side supports on the same hole-aligning moving parts are arranged circumferentially.

A synchronous adjustment component is provided on the support plate for driving the hole-aligning moving parts to move synchronously.

[0007] The cap locking mechanism includes linkage plates evenly spaced along the circumference of the support plate. The linkage plates are fixedly connected to the corresponding hole moving parts via connecting rods. An L-shaped part is slidably arranged on the upper part of the linkage plate. A pressing limit plate for pressing the cap downward is hinged on the upper part of the vertical section of the L-shaped part away from the axis of the support plate.

[0008] As a preferred embodiment of the present invention, the upper part of the support plate is provided with a supporting circular plate that slides up and down through a guide pillar, and the upper part of the support plate is provided with an adjusting stud that is rotatably connected to the supporting circular plate.

[0009] As a preferred embodiment of the present invention, the aperture adjustment assembly includes a tube frame fixedly installed on the side of the hole moving member near the axis of the support plate member, a hole edge support member arranged circumferentially on the tube frame, a horizontal section of the hole edge support member slidably connected to the tube frame along the radial direction of the tube frame, and a motor drive rotating ring with an end face thread rotatably disposed inside the tube frame, the motor drive rotating ring being threadedly engaged with the hole edge support member on the same tube frame.

[0010] As a preferred embodiment of the present invention, the aperture adjustment assembly further includes a servo motor fixedly installed on the side of the aperture moving member away from the axis of the support disk, and the output shaft of the servo motor is connected to the lower part of the motor drive ring via a synchronous belt.

[0011] As a preferred embodiment of the present invention, the pressing and limiting plate has a through hole extending vertically on the side away from the axis of the support plate, and the through hole is arranged coaxially with the tube frame on the corresponding hole moving part.

[0012] As a preferred embodiment of the present invention, the hole guide assembly includes a synchronous moving plate that is slidably mounted on the hole moving member. A positioning tube arranged coaxially with the tube frame is fixedly installed on the upper part of the synchronous moving plate. A plurality of support plates that slide radially are arranged at equal intervals along the circumference of the positioning tube. The support plates are connected to the hole edge support member at the corresponding position through a connecting part. A cylinder that drives the synchronous moving plate to move up and down is fixedly installed in the middle of the hole moving member.

[0013] As a preferred embodiment of the present invention, the connecting part includes a connecting sliding plate that is slidably disposed at the lower part of the perforated plate along the length direction of the perforated plate. The connecting sliding plate is slidably connected to the hole edge support member at the corresponding position. A plurality of positioning holes are equally spaced on the connecting sliding plate. A locking connecting rod for inserting into the positioning hole is slidably disposed inside the perforated plate.

[0014] As a preferred embodiment of the present invention, a synchronous moving rod is slidably arranged inside the positioning tube, a helical spring is arranged between the synchronous moving rod and the positioning tube, a conical protective cover is fixedly installed on the top of the synchronous moving rod, the lower side of the synchronous moving rod is located at the lower part of the positioning tube, a baffle for blocking the synchronous moving rod from moving downward is fixedly installed on the hole moving part, and all positioning tubes are connected to an air pump fixedly installed on the operating table through hoses and pipes.

[0015] As a preferred embodiment of the present invention, the synchronous adjustment component includes a rotating ear plate rotatably disposed on the lower part of the support plate at a position coaxial with the support plate. The rotating ear plate is hinged to each pair of moving parts through a linkage support plate. A drive stud is rotatably disposed inside the support plate and threadedly connected to one of the pair of moving parts.

[0016] As a preferred embodiment of the present invention, the retractable assembly includes a hydraulic cylinder fixedly installed at the axial position of the upper part of the support plate, a lifting bearing plate fixedly installed on the upper part of the telescopic section of the hydraulic cylinder, the lifting bearing plate being slidably connected to the horizontal section of the L-shaped component, and a spring telescopic rod being hinged between the linkage plate and the pressing limit plate at the corresponding position.

[0017] The beneficial effects of this invention are as follows: First, the synchronous positioning component of this invention can drive the hole edge support to a designated position through the hole moving component, so that the hole edge support can stably support the lower side of the edge of the diaphragm spring mounting hole on the pressure cap, thereby preventing the drill bit from deforming the hole edge support and ensuring the drilling quality. Moreover, through the cooperation of the hole position guiding component and the hole diameter adjusting component, the diaphragm spring mounting hole on the pressure cap can be quickly and accurately positioned to the position of the hole edge support, thereby improving the processing efficiency.

[0018] Second, the combination of the hole position guide component and the hole diameter adjustment component in this invention can also quickly adjust the position of the hole edge support on the same pair of hole moving parts, so that the hole edge support can be quickly aligned to the edge position of the diaphragm spring mounting hole with different inner diameters. This improves processing efficiency and accuracy, while increasing the adaptability of the pressure cap to diaphragm spring mounting holes with different inner diameters.

[0019] Third, the present invention uses a hole-moving component to synchronously adjust the position of the pressing limit plate through a linkage plate, so that the pressing limit plate can always press on the position of the pressure cap with the hole-edge support component.

[0020] Fourth, the pressure cap locking mechanism of this invention can automatically retract and unfold the pressing limit plate without changing the position of the hole moving part, so that the position of the pressure cap can be quickly locked and unlocked, thereby quickly replacing the pressure cap and further improving processing efficiency.

[0034] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0035] See Figure 1 , Figure 2 and Figure 11 A clutch cover drilling and forming processing equipment includes an operating table 1, on which a drilling assembly 2 is slidably arranged in the vertical direction. The operating table 1 is also provided with an anti-deformation mechanism 3 for supporting the drilling position of the cover. The equipment also includes a cover locking mechanism 4 for clamping and fixing the cover.

[0036] When drilling is required on the diaphragm spring mounting hole on the clutch cover, the position of the anti-deformation mechanism 3 is first adjusted. The anti-deformation mechanism 3 can simultaneously drive the position of the cover locking mechanism 4 to be adjusted. Then, the operator manually places the cover on the anti-deformation mechanism 3. The anti-deformation mechanism 3 quickly and accurately positions the diaphragm spring mounting hole on the cover. At the same time, it can also support the lower edge of the diaphragm spring mounting hole. Then, the cover locking mechanism 4 locks the position of the cover. Then, the drilling assembly 2 is moved downward to drill the diaphragm spring mounting hole on the cover.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The anti-deformation mechanism 3 includes a support plate 31 fixedly installed on the upper part of the operating table 1. Several hole-aligning moving parts 32 are equally spaced along the circumference of the upper part of the support plate 31 and slide along the radial direction. A hole diameter adjustment component 33 is provided on the hole-aligning moving parts 32. The hole diameter adjustment component 33 includes a tube frame 331 fixedly installed on the side of the hole-aligning moving parts 32 near the axis of the support plate 31. Hole edge support parts 34 are equally spaced along the circumference of the upper part of the tube frame 331. The hole edge support parts 34 have an L-shaped structure. The horizontal section of the hole edge support parts 34 is slidably connected to the tube frame 331 along the radial direction.

[0038] See Figure 2 The upper part of the support plate 31 is provided with a support circular plate 311 that slides up and down through a guide column. The upper part of the support plate 31 is provided with an adjusting stud 312 that rotates, and the adjusting stud 312 is threadedly connected to the support circular plate 311.

[0039] When drilling is required for the diaphragm spring mounting hole on the cap, the operator manually rotates the adjusting stud 312, causing the adjusting stud 312 to move the supporting circular plate 311 up and down. This allows the supporting circular plate 311 to move up and down relative to the upper side of the hole edge support 34, so that when the operator places the cap on the supporting circular plate 311, the edge of the diaphragm spring mounting hole on the cap can fit against the upper side of the vertical section of the hole edge support 34, thus allowing the hole edge support 34 to support the edge of the diaphragm spring mounting hole on the cap.

[0040] See Figure 1 and Figure 8 The anti-deformation mechanism 3 also includes a synchronous adjustment component 36 disposed on the support plate 31. The synchronous adjustment component 36 includes a rotating ear plate 361 rotatably disposed on the lower part of the support plate 31 at a coaxial position. The rotating ear plate 361 is hinged to each hole moving part 32 through a linkage support plate 362. A drive stud 363 is rotatably disposed inside the support plate 31 and threadedly connected to one of the hole moving parts 32.

[0041] After the height of the supporting circular plate 311 is adjusted, the operator manually rotates the drive stud 363, causing the drive stud 363 to drive the corresponding hole-aligning moving parts 32 to move closer to the axis of the support plate 31. At the same time, the hole-aligning moving parts 32 connected to the drive stud 363 push the rotating ear plate 361 to rotate through the corresponding linkage support plate 362. The rotating ear plate 361 drives the corresponding hole-aligning moving parts 32 to move synchronously through the other linkage support plates 362, thereby causing all the hole-aligning moving parts 32 to move synchronously towards the axis of the support plate 31.

[0042] The hole moving component 32 drives the hole edge support component 34 to move synchronously through the bobbin holder 331 until the bobbin holder 331 moves to the coaxial position of the drill bit at the corresponding position on the drilling assembly 2, thereby moving the hole edge support component 34 to the periphery of the drill bit at the corresponding position on the drilling assembly 2. Then, the position of the diaphragm spring mounting hole on the pressure cap can be quickly and accurately positioned by the position of the hole edge support component 34.

[0043] See Figure 2 and Figure 9 The cap locking mechanism 4 includes a linkage plate 41 that is evenly spaced along the circumference of the support plate 31. The linkage plate 41 is fixedly connected to the corresponding hole moving part 32 through the connecting support rod 42. An L-shaped part 43 is slidably arranged on the upper part of the linkage plate 41. A pressing limit plate 44 for pressing the cap downward is hinged on the upper part of the vertical section of the L-shaped part 43 away from the axis of the support plate 31. The cap locking mechanism 4 also includes a retracting assembly 45 for quickly unfolding and retracting the pressing limit plate 44.

[0044] Continue reading Figure 2 and Figure 9 The retractable assembly 45 includes a hydraulic cylinder 451 fixedly installed on the upper axial position of the support plate 31. A lifting bearing plate 452 is fixedly installed on the upper part of the telescopic section of the hydraulic cylinder 451. The lifting bearing plate 452 is slidably connected to the horizontal section of the L-shaped part 43. A spring telescopic rod 453 is hinged between the linkage plate 41 and the corresponding pressing limit plate 44. The pressing limit plate 44 has a through hole 441 on the side away from the axis of the support plate 31. The through hole 441 is coaxially arranged with the tube frame 331 on the corresponding hole moving part 32.

[0045] In the initial state, the telescopic section of the hydraulic cylinder 451 is in a retracted state, which causes the hydraulic cylinder 451 to press down on the L-shaped part 43 through the lifting support plate 452. The L-shaped part 43 drives the pressing limit plate 44 to a position close to the linkage plate 41, which causes the spring telescopic rod 453 to be in a compressed state. As a result, the spring telescopic rod 453 pushes the pressing limit plate 44 to a horizontal position through its own elastic force.

[0046] When the hole moving part 32 moves, it drives the corresponding linkage plate 41 to move synchronously through the connecting support rod 42. The linkage plate 41 drives the pressing limit plate 44 to move synchronously through the L-shaped part 43, so that the pressing limit plate 44 in the horizontal state drives the through hole 441 on it to always be in the same position as the corresponding tube frame 331.

[0047] When the cap needs to be placed on the support plate 311, the telescopic section of the extended hydraulic cylinder 451 drives the lifting support plate 452 to move upward. The lifting support plate 452 drives all the pressing limit plates 44 to move upward synchronously through the L-shaped part 43, while stretching the spring telescopic rod 453 to full extension. Then, the pressing limit plates 44 continue to move upward, causing the spring telescopic rod 453 to pull the pressing limit plates 44 downward. Then, the operator holds the cap through all the pressing limit plates 44 and places it on the support plate 311.

[0048] See Figure 1 , Figure 3 , Figure 4 and Figure 6 The anti-deformation mechanism 3 also includes a hole position guide assembly 35 disposed on the hole-aligning moving part 32. The hole position guide assembly 35 includes a synchronous moving plate 351 that is slidably disposed on the hole-aligning moving part 32. A positioning tube 352 arranged coaxially with the tube frame 331 is fixedly installed on the upper part of the synchronous moving plate 351. A synchronous moving rod 37 is slidably disposed inside the positioning tube 352. A helical spring is disposed between the synchronous moving rod 37 and the positioning tube 352. A conical protective cover 371 is fixedly installed on the top of the synchronous moving rod 37.

[0049] In the initial state, the helical spring pushes the synchronous moving rod 37 downward, causing the synchronous moving rod 37 to drive the conical protective cover 371 to press against the upper part of the positioning tube 352. When the operator places the pressure cap on the supporting circular plate 311, the operator manually adjusts the position of the pressure cap so that the diaphragm spring mounting hole of the pressure cap moves to the upper part of the conical protective cover 371. The shape of the conical protective cover 371 guides the diaphragm spring mounting hole of the pressure cap, so that the diaphragm spring mounting hole on the pressure cap moves smoothly to the outside of the positioning tube 352.

[0050] Continue reading Figure 1 , Figure 3 , Figure 4 and Figure 6 The hole guide assembly 35 also includes a plurality of support plates 353 that are equally spaced along the circumference of the positioning tube 352 and slide radially on its upper part. The support plates 353 are connected to the hole edge support members 34 at corresponding positions through the connecting part 354. A cylinder 355 that drives the synchronous moving plate 351 to move up and down is fixedly installed in the middle of the hole moving member 32.

[0051] See Figure 6 and Figure 7The connecting part 354 includes a connecting sliding plate 3541 that is slidably disposed at the lower part of the supporting plate 353 along the length direction of the supporting plate 353. The connecting sliding plate 3541 is slidably connected to the hole edge support member 34 at the corresponding position. A plurality of positioning holes 3542 are equally spaced on the connecting sliding plate 3541. A locking connecting rod 3543 for inserting into the positioning hole 3542 is slidably disposed inside the supporting plate 353.

[0052] In the initial state, the hole edge support 34 is positioned close to the axis of the corresponding tube frame 331, so that the hole edge support 34 drives the corresponding hole support plate 353 to retract inside the positioning tube 352 through the connecting sliding plate 3541. When the diaphragm spring mounting hole of the cover is located on the outside of the positioning tube 352, the position of the diaphragm spring mounting hole of the cover corresponds to the position of the hole support plate 353 on the positioning tube 352.

[0053] In this embodiment, the telescopic section of the cylinder 355 can drive the positioning tube 352 at the corresponding position to move downward through the synchronous moving plate 351, so that the upper side of the positioning tube 352 moves to the lower part of the upper side of the hole edge support 34 at the corresponding position, thereby enabling drilling of the pressure cap with different numbers of diaphragm spring mounting holes.

[0054] See Figure 1 , Figure 4 and Figure 5 The aperture adjustment assembly 33 also includes a motor drive ring 332 with an end face thread that is rotatably disposed inside the tube holder 331. The motor drive ring 332 is threadedly engaged with the hole edge support 34 on the same tube holder 331. A servo motor 333 is fixedly installed on the side of the hole moving part 32 away from the axis of the support plate 31. The output shaft of the servo motor 333 is connected to the lower part of the motor drive ring 332 through a synchronous belt.

[0055] When the diaphragm spring mounting hole is located at the position of the support plate 353, the servo motor 333 is started to drive the motor drive ring 332 to rotate, so that the motor drive ring 332 drives the hole edge support 34 on it to move synchronously away from the axis of the corresponding tube frame 331. The hole edge support 34 drives the support plate 353 to move synchronously through the connecting sliding plate 3541, so that the support plate 353 moves synchronously to abut against the inner wall of the diaphragm spring mounting hole, thereby quickly positioning the diaphragm spring mounting hole to the coaxial position of the corresponding drill bit on the drilling assembly 2, so as to quickly determine the position of the pressure cap.

[0056] At the same time, the hole edge support members 34 on the same tube frame 331 are evenly arranged at the lower edge of the diaphragm spring mounting hole, so that the hole edge support members 34 can effectively and stably support the edge position of the diaphragm spring mounting hole. Then, the telescopic section of the hydraulic cylinder 451 is retracted, so that the pressing limit plate 44 swings to a horizontal position and presses downward on the corresponding position of the pressure cap. Thus, the position of the pressure cap is locked by the clamping of the pressure cap diaphragm spring mounting hole position by the pressing limit plate 44 and the hole edge support members 34.

[0057] In this embodiment, when the required drilling diameters of diaphragm spring mounting holes with the same inner diameter are different, the operator manually pulls up the locking connecting rod 3543, causing the lower end of the locking connecting rod 3543 to move to the upper part of the corresponding support plate 353. Then, the operator manually moves the distance between the hole edge support 34 and the support plate 353, causing the hole edge support 34 to drive the connecting sliding plate 3541 to slide on the support plate 353. Then, the operator manually moves the locking connecting rod 3543 downward to insert it into the corresponding positioning hole 3542, thereby locking the support plate 353 and the connecting sliding plate 3541 into a whole again.

[0058] This results in the hole support 353 abutting against the inner wall of the diaphragm spring mounting hole with the same inner diameter, with the hole edge support 34 positioned differently from the inner wall of the diaphragm spring mounting hole, in order to accommodate drilling requirements of different sizes.

[0059] See Figure 1 , Figure 4 , Figure 6 and Figure 10 The lower side of the synchronous moving rod 37 is located at the lower part of the positioning tube 352. A baffle 373 for blocking the synchronous moving rod 37 from moving downward is fixedly installed on the hole moving part 32. All positioning tubes 352 are connected to the air pump 372 fixedly installed on the operating table 1 through hoses and pipes.

[0060] When the position of the pressure cap is locked by pressing the limit plate 44, the telescopic section of the extension cylinder 355 drives the positioning tube 352, which extends to the upper part of the pressure cap, to move downward to the lower part of the pressure cap. This causes the positioning tube 352 to make way for the drill bit. The positioning tube 352 drives the synchronous moving rod 37 to move synchronously until the lower end of the synchronous moving rod 37 abuts against the baffle 373. Then the positioning tube 352 continues to move downward. Since the synchronous moving rod 37 cannot move due to the obstruction of the baffle 373, the conical protective cover 371 moves upward relative to the positioning tube 352, thereby causing the conical protective cover 371 to no longer seal the upper end of the positioning tube 352.

[0061] Subsequently, the drill bit on the drilling assembly 2 is driven to drill the diaphragm spring mounting hole of the pressure cap. At the same time, the air pump 372 is started to blow high-speed airflow through the hose, pipe and positioning tube 352 to the lower edge of the diaphragm spring mounting hole. This drives the heat generated at the lower edge of the diaphragm spring mounting hole during drilling, thereby cooling the area at the lower part of the diaphragm spring mounting hole that is difficult to contact with coolant, preventing the pressure cap from plastic deformation due to high temperature, and further improving the quality of drilling.

[0062] When drilling the pressure cap, the present invention further includes the following steps: First, manually rotate the adjusting stud 312 to drive the supporting circular plate 311 to adjust up and down to a suitable position, and then manually rotate the driving stud 363 to move to the lower periphery of the corresponding drill bit through the hole moving part 32.

[0063] In the second step, the through hole 441 of the horizontal pressing limit plate 44 driven by the hole moving part 32 is always in the same position as the corresponding tube frame 331. Then, the extension section of the hydraulic cylinder 451 drives the pressing limit plate 44 to move upward and deflect downward. Then, the operator holds the pressure cap through all the pressing limit plates 44 and places it on the supporting round plate 311.

[0064] The third step involves the operator manually adjusting the position of the pressure cap so that the diaphragm spring mounting hole of the pressure cap moves to the upper part of the conical protective cover 371. The shape of the conical protective cover 371 guides the diaphragm spring mounting hole of the pressure cap, allowing the diaphragm spring mounting hole on the pressure cap to move smoothly to the outside of the positioning tube 352.

[0065] Fourth step, start the servo motor 333 to drive the hole support plate 353 to abut against the inner wall of the diaphragm spring mounting hole through the hole edge support 34, so that the diaphragm spring mounting hole is quickly positioned to the coaxial position of the corresponding drill bit on the drilling assembly 2, and at the same time, the hole edge support 34 is evenly arranged at the lower edge of the diaphragm spring mounting hole.

[0066] Fifth, the telescopic section of the hydraulic cylinder 451 is then retracted, causing the pressing limit plate 44 to swing to a horizontal position and press downward onto the corresponding position of the pressure cap. Thus, the position of the pressure cap is locked by the clamping of the pressure cap diaphragm spring mounting hole position by the pressing limit plate 44 and the hole edge support 34.

[0067] The sixth step involves extending the telescopic section of the cylinder 355, which drives the positioning tube 352, which extends to the upper part of the pressure plate, to move downward to the lower part of the pressure plate, making room for the drill bit. The positioning tube 352 continues to move, so that the conical protective cover 371 no longer seals the upper end of the positioning tube 352.

[0068] Step 7: The drill bit on the drilling assembly 2 is used to drill the diaphragm spring mounting hole of the pressure plate. At the same time, the air pump 372 is started to blow high-speed air through the hose, pipe and positioning tube 352 to the lower edge of the diaphragm spring mounting hole.

[0069] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered within the protection scope of the present invention.
