Description

Technical Field

[0001] This invention relates to the field of camshaft machining support devices, and more particularly to a support mechanism for a camshaft grinding machine. Background Technology

[0002] Camshafts are widely used in gasoline and diesel engines to control the opening and closing of valves in the valve train system. The quality of their machining directly determines the engine's performance. In the camshaft manufacturing process, the camshaft is first pre-cast using molds, and then finely ground on a grinding machine to achieve high precision.

[0003] In existing technologies, most grinding machines include a grinding mechanism and a clamping mechanism. The clamping mechanism securely holds the camshaft and drives it to rotate, while the grinding mechanism grinds the camshaft. Since radial runout is unavoidable during camshaft grinding, when high grinding accuracy is required, a support frame is usually fixedly installed on the grinding machine's worktable to support the camshaft, prevent radial runout, and ensure grinding accuracy.

[0004] However, multiple support brackets are required to ensure the support effect, and when the camshaft is ground at the supported position, it is quite troublesome to manually adjust the position of the support brackets. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a support mechanism for a camshaft grinding machine, which solves the problems in the prior art that require the installation of multiple support frames to ensure the support effect, and that it is cumbersome to manually adjust the position of the support frames when grinding the camshaft in the supported position.

[0006] The present invention solves the above-mentioned technical problems through the following technical means:

[0007] A support mechanism for a camshaft grinding machine is mounted on a worktable below the clamping mechanism of the camshaft grinding machine for supporting the camshaft. The support mechanism includes a base and a support member. The base is slidably mounted on the worktable, and the support member is slidably disposed on the base. A push plate for pushing the support member is slidably disposed on the base. A one-way limiting component is disposed between the base and the support member to limit the movement of the support member in the direction of the camshaft. An unlocking component is disposed on the base to release the one-way limiting component from the support member. A driving member is disposed on the base, one end of which is slidably connected to the base, and the other end is fixedly connected to the grinding mechanism of the camshaft grinding machine. A transmission component is disposed between the driving member and the push plate, so that the driving member can drive the push plate to move when it moves. A stop is disposed on the driving member to drive the unlocking component to unlock.

[0008] Furthermore, the base is provided with an installation block, the support is provided on the installation block, the installation block is provided with a first sliding groove, and a slider is fixedly connected to the bottom of the support, the slider being slidably engaged in the first sliding groove.

[0009] Furthermore, the one-way limiting component includes a limiting plate and multiple limiting teeth. The multiple limiting teeth are fixedly installed on the top of the limiting plate. The slider has several limiting grooves, and the limiting teeth can be engaged in the limiting grooves. Slide rails are provided on both sides of the outer end of the first slide groove. A limiting rod is provided in the slide rail. A first through hole is provided at both ends of the limiting plate. The limiting rod is inserted into the first through hole. A first spring is sleeved on the limiting rod. One end of the first spring is connected to the bottom of the slide rail, and the other end is connected to the bottom of the limiting plate.

[0010] Furthermore, the unlocking component includes a plate body, a connecting plate integrally formed at the bottom of the limiting plate, connecting shafts provided on both sides of the connecting plate, connecting rods provided on both sides of the plate body near the connecting plate end, a second sliding groove provided on the connecting rod, the connecting shaft being movably connected in the second sliding groove, an installation groove provided at the bottom of the mounting block, a shaft hole provided on the plate body, a rotating shaft inserted into the shaft hole, and both ends of the rotating shaft being fixedly connected to the two side walls of the installation groove respectively.

[0011] Furthermore, the driving component includes a driving bar and a connecting seat. A third sliding groove is provided at the bottom of the mounting groove. The driving bar is slidably disposed in the third sliding groove. The driving bar is fixedly connected to the connecting seat. The connecting seat is fixedly connected to the grinding mechanism of the camshaft grinding machine.

[0012] Furthermore, the transmission assembly includes a drive rack, a driven rack, and a transmission gear. The drive rack is fixedly mounted on the drive rack, the driven rack is fixedly connected to the push plate, and the transmission gear is rotatably mounted in the mounting groove. The drive rack meshes with the transmission gear below, and the driven rack meshes with the transmission gear above.

[0013] Furthermore, the transmission gear includes a large gear and small gears disposed on both sides of the large gear. The driving rack meshes with the large gear, and two driven racks are provided, each of which meshes with a corresponding small gear.

[0014] Furthermore, a hinge seat is provided at one end of the drive bar near the push plate, and the stop block is rotatably mounted on the hinge seat. The top of the stop block can abut against the lower end of the plate. A stop angle is provided at the hinge end of the stop block and the hinge seat, and the stop angle is located on the side away from the connecting seat.

[0015] Furthermore, a column is provided in the first slide groove, and a sliding hole is provided on the slider. The slider is slidably sleeved on the column through the sliding hole. A second spring is sleeved on the column. One end of the second spring is connected to the inner wall of the first slide groove, and the other end is fixedly connected to the end wall of the slider. A second through hole is provided on the push plate, and the push plate is slidably sleeved on the column through the second through hole.

[0016] Furthermore, reinforcing plates are provided on both sides of the support member, and the mounting block is located between the two reinforcing plates.

[0017] The beneficial effects of this invention are:

[0018] 1. This invention, by setting up a support mechanism, a push plate, a one-way limiting component, an unlocking component, a driving component, a transmission component, and a stop block, allows the grinding mechanism to move axially. When the grinding mechanism moves, the driving bar of the driving component can drive the base to move, thereby driving the support mechanism to move. This ensures that the support mechanism follows the grinding mechanism and always supports both sides of the grinding area of ​​the grinding mechanism, eliminating the need for manual adjustment of the support position. When the grinding mechanism moves laterally, the push plate can be driven to move through the driving rack, transmission gear, and driven rack. Without the need for a separate power source, the push plate can push the slider towards the camshaft, allowing the support component to move to the camshaft and support it. Moreover, only one support component is needed to ensure the support effect.

[0019] 2. The present invention limits the direction of movement of the support by setting a one-way limiting component. When the support moves towards the camshaft, it prevents the support from retracting and maintains the supporting force of the support on the camshaft.

[0020] 3. By setting an unlocking component and a stop, after the grinding mechanism finishes grinding, when it retracts, the stop will push the plate to rotate counterclockwise. The plate will pull the connecting plate downward through the connecting rod, thereby causing the limiting tooth to disengage from the limiting groove, releasing the one-way limiting component from limiting the support, so that the support can be reset away from the camshaft.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1-9As shown, in this embodiment, the camshaft grinding machine includes a grinding mechanism 91, a clamping mechanism, and a base 93. The clamping mechanism includes a headstock 921 and a tailstock 922. The grinding mechanism 91, headstock 921, and tailstock 922 are all mounted on the worktable 931 of the base 93. The tips of the headstock 921 and tailstock 922 press against both ends of the camshaft 94 and drive the camshaft 94 to rotate. During grinding, the grinding mechanism 91 performs axial movement and lateral movement. Axial movement changes the grinding position, and lateral movement moves closer to the camshaft 94 for feed grinding. A support mechanism for a camshaft grinding machine is provided by the present invention. The support mechanism is mounted on the worktable 931 below the clamping mechanism of the camshaft grinding machine to support the camshaft 94 and prevent the camshaft 94 from swaying radially during grinding by the grinding mechanism 91.

[0033] In this embodiment, the support mechanism includes a base 1 and a support member 2. The base 1 is slidably mounted on the workbench 931. In this embodiment, a slot 11 is provided at the bottom of the base 1, and the base 1 is slidably engaged on the workbench 931 through the slot 11. The support member 2 is slidably mounted on the base 1. Specifically, a mounting block 12 is provided on the base 1, and the support member 2 is mounted on the mounting block 12. A first sliding groove 121 is provided on the mounting block 12, and a slider 21 is fixedly connected to the bottom of the support member 2. The slider 21 is slidably engaged in the first sliding groove 121. This allows the support member 2 to be slidably mounted on the base 1. In this embodiment, reinforcing plates 22 are provided on both sides of the support member 2, and the mounting block 12 is located between the two reinforcing plates 22. The reinforcing plates 22 ensure the support effect of the support member 2 and also ensure the stability of the support member 2 when it moves.

[0034] In this embodiment, the support member 2 is provided with two support ears 23, and the support ears 23 are provided with support grooves 231. The groove walls of the support grooves 231 abut against the camshaft 94, thus providing support. It should be noted that the camshaft 94 includes a shaft body and a cam. When the grinding mechanism 91 grinds the cam, the two support ears 23 are supported on the shaft body on both sides of the cam being ground to ensure the support effect. Moreover, the two support ears 23 can be set to be adjustable and fixed on the support member 2, so as to adapt to the grinding support of different models of camshaft 94.

[0035] In this embodiment, a push plate 3 is slidably provided on the base 1 for pushing the support member 2 to move. When the push plate 3 moves toward the camshaft 94, it can push the slider 21 to move toward the camshaft 94 so that the support member 2 can move to the camshaft 94 and support the camshaft 94.

[0036] In this embodiment, a one-way limiting component is provided between the base 1 and the support member 2. The one-way limiting component is used to limit the movement of the support member 2 towards the camshaft 94. When the support member 2 moves towards the camshaft 94, it prevents the support member 2 from retracting and maintains the supporting force of the support member 2 on the camshaft 94. Specifically, the one-way limiting component includes a limiting plate 41 and multiple limiting teeth 42. The multiple limiting teeth 42 are fixedly installed on the top of the limiting plate 41. The slider 21 is provided with a number of limiting grooves 211. Slide rails 13 are provided on both sides of the outer end of the first slide groove 121. A limiting rod 131 is provided in the slide rail 13. A first through hole 411 is provided at both ends of the limiting plate 41. The limiting rod 131 is inserted into the first through hole 411. A first spring 132 is sleeved on the limiting rod 131. One end of the first spring 132 is connected to the bottom of the slide rail 13, and the other end is connected to the bottom of the limiting plate 41. The first spring 132 is used to keep the limiting plate 41 moving upward, so that the limiting tooth 42 is locked in the limiting groove 211, limiting the slider 21 to move in one direction, thereby achieving the purpose of limiting the support member 2 in one direction.

[0037] In this embodiment, an unlocking component is provided on the base 1. The unlocking component is used to release the one-way limiting component from the support member 2. Specifically, the unlocking component includes a plate 5. A connecting plate 43 is integrally formed on the bottom of the limiting plate 41. A connecting shaft 431 is provided on both sides of the connecting plate 43. A connecting rod 51 is provided on both sides of the plate 5 near the end of the connecting plate 43. A second sliding groove 511 is provided on the connecting rod 51. The connecting shaft 431 is movably connected in the second sliding groove 511. An installation groove 122 is provided at the bottom of the mounting block 12. A shaft hole 52 is provided on the plate 5. The shaft hole 52 is located at the middle position in the length direction of the plate 5. A rotating shaft 521 is inserted into the shaft hole 52. The two ends of the rotating shaft 521 are fixedly connected to the two side walls of the installation groove 122 respectively. When plate 5 is rotated counterclockwise, connecting plate 43 can be pulled down by connecting rod 51, thereby disengaging limiting tooth 42 from limiting groove 211, releasing the one-way limiting component from limiting support 2, so that support 2 can be moved away from camshaft 94.

[0038] In this embodiment, a driving component is provided on the base 1. One end of the driving component is slidably connected to the base 1, and the other end is fixedly connected to the grinding mechanism 91 of the camshaft grinding machine. Specifically, the driving component includes a driving bar 61 and a connecting seat 62. A third sliding groove 14 is provided at the bottom of the mounting groove 122. The driving bar 61 is slidably disposed in the third sliding groove 14 and is fixedly connected to the connecting seat 62. The connecting seat 62 is fixedly connected to the grinding mechanism 91 of the camshaft grinding machine by fixing bolts. Specifically, the connecting seat 62 is fixedly connected to the outer shell of the grinding wheel by fixing bolts. When the grinding mechanism 91 moves axially, the driving bar 61 of the driving component can drive the base 1 to move, thereby driving the support mechanism to move, so that the support mechanism follows the movement of the grinding mechanism 91, keeping the support mechanism always supporting both sides of the grinding area of ​​the grinding mechanism 91. There is no need to manually adjust the support position, and the support effect can be guaranteed by simply setting one support component 2.

[0039] In this embodiment, a transmission assembly is provided between the driving component and the push plate 3, so that the push plate 3 can be moved when the driving component moves. Specifically, the transmission assembly includes a driving rack 71, a driven rack 72, and a transmission gear 73. The driving rack 71 is fixedly installed on the driving rack 61, the driven rack 72 is fixedly connected to the push plate 3, and the transmission gear 73 is rotatably installed in the mounting groove 122. The driving rack 71 meshes with the lower part of the transmission gear 73, and the driven rack 72 meshes with the upper part of the transmission gear 73. When the grinding mechanism 91 moves laterally, the push plate 3 can be moved by the driving rack 71, the transmission gear 73, and the driven rack 72. Without the need for a separate power source, the push plate 3 can push the slider 21 to move towards the camshaft 94, so that the support member 2 moves to the camshaft 94 to support the camshaft 94.

[0040] In this embodiment, a limiting wheel 16 is provided above the transmission gear 73, and the limiting wheel 16 presses on the driven rack 72 to ensure stable transmission of the driven rack 72.

[0041] In this embodiment, a stop block 8 is provided on the driving component, which is used to drive the unlocking component to unlock. Specifically, a hinge seat 611 is provided at the end of the driving bar 61 near the push plate 3. The stop block 8 is rotatably mounted on the hinge seat 611. The top of the stop block 8 can abut against the lower end of the plate 5. A stop angle 81 is provided at the hinge end of the stop block 8 and the hinge seat 611. The stop angle 81 is located on the side away from the connecting seat 62. By setting the stop angle 81, the stop block 8 can only rotate clockwise. After the grinding mechanism 91 finishes grinding, when it retracts, the driving bar 61 can drive the stop block 8 to approach the plate 5. During the continuous movement of the stop block 8, it will push the plate 5 to rotate counterclockwise. The plate 5 pulls the connecting plate 43 downward through the connecting rod 51, thereby causing the limiting tooth 42 to disengage from the limiting groove 211, releasing the one-way limiting component from limiting the support member 2, so that the support member 2 can move away from the camshaft 94.

[0042] In this embodiment, a column 15 is provided in the first slide groove 121, and a sliding hole 212 is provided on the slider 21. The slider 21 is slidably sleeved on the column 15 through the sliding hole 212. A second spring 151 is sleeved on the column 15. One end of the second spring 151 is connected to the inner wall of the first slide groove 121, and the other end is fixedly connected to the end wall of the slider 21. By providing the second spring 151, when the slider 21 moves towards the camshaft 94, the second spring 151 can be compressed. When the one-way limiting component releases the limiting of the support member 2, the second spring 151 returns to its original deformation, which can push the support member 2 away from the camshaft 94, so that the support member 2 automatically resets, so that the grinding mechanism 91 drives the support mechanism to move axially. A second through hole 31 is provided on the push plate 3. The push plate 3 is slidably sleeved on the column 15 through the second through hole 31. By sliding the push plate 3 on the column 15, the push plate 3 is supported and limited, ensuring the stability of the movement of the push plate 3.

[0043] In this embodiment, the transmission gear 73 includes a large gear 731 and small gears 732 disposed on both sides of the large gear 731. The driving rack 71 meshes with the large gear 731, and two driven racks 72 are provided, each meshing with a corresponding small gear 732. By setting the large gear 731 and small gears 732, and changing the transmission ratio of the driving rack and driven rack 72, the situation where the support member 2 has not yet supported the camshaft 94 after the grinding mechanism 91 has engaged with the cam of the camshaft 94 is avoided. In this embodiment, a third spring 32 is provided between the push plate 3 and the slider 21. By setting the third spring 32, the situation where the transmission ratio is not set accurately, and the push plate 3 cannot continue to move towards the camshaft 94 even when the support member 2 has already supported the camshaft 94, is avoided, which would prevent the grinding mechanism 91 from feeding smoothly. It should be noted that the elastic coefficient of the second spring 151 is much greater than that of the third spring 32, so as to avoid the second spring 151 being blocked by the third spring 32 when pushing the support member 2 to reset, which would result in the support member 2 being unable to reset normally.

[0044] The working principle of this invention is as follows:

[0045] When the main control unit of the grinding machine controls the grinding mechanism 91 to move axially, the drive bar 61 of the drive component drives the base 1 to move, thereby driving the support mechanism to move, and the support mechanism follows the grinding mechanism 91. During this process, when the stop block 8 is blocked by the plate 5, the plate 5 pushes the stop block 8 to rotate clockwise, so that the stop block 8 can pass smoothly through the plate 5.

[0046] After the grinding mechanism 91 moves to the cam to be ground, the grinding mechanism 91 begins to move laterally. As the grinding mechanism 91 gradually approaches the cam, the drive bar 61 drives the push plate 3 to move through the drive rack 71, the transmission gear 73 and the driven rack 72. The push plate 3 pushes the slider 21 to move through the third spring 32. The slider 21 moves the support member 2 to the camshaft 94 to support the camshaft 94. When the slider 21 moves toward the camshaft 94, it compresses the second spring 151.

[0047] After the grinding mechanism 91 completes the grinding of the cam by reciprocating movement, it begins to gradually move away from the camshaft 94, i.e., the retraction process. During this process, the stop block 8 gradually approaches the plate body 5. As the stop block 8 continues to move, it pushes the plate body 5 to rotate counterclockwise. The plate body 5 pulls the connecting plate 43 downward through the connecting rod 51, thereby causing the limiting tooth 42 to disengage from the limiting groove 211, releasing the one-way limiting component from limiting the support member 2. The second spring 151 returns to its original deformation and pushes the support member 2 away from the camshaft 94, so that the support member 2 automatically resets.

[0048] After the grinding mechanism 91 is reset, it can drive the support mechanism to move axially again to continue grinding the camshaft 94.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
