Description

Technical Field

[0001] This application relates to the technical field of shift fork machining, and in particular to a clamping device for shift fork machining. Background Technology

[0002] A shift fork is a component on a car's gearbox. It is connected to the gear lever and located at the lower end of the lever. The shift fork is used to shift the intermediate gear wheel, thereby changing the input / output speed ratio.

[0003] During the machining of shift forks, a clamping device is required to clamp and fix the shift forks. Currently, the clamping device includes a machining table, a cylinder vertically set on one side of the machining table, and a pressure plate located above the machining table and fixedly connected to the moving end of the cylinder. A machining groove is opened on the top surface of the machining table, and the fixed end of the cylinder is fixedly connected to the machining table. When machining the shift fork, the shift fork shaft is first placed in the machining groove. After the shift fork shaft enters the machining groove, the operator drives the pressure plate downward through the cylinder to abut against the shift fork shaft, so that the pressure plate clamps and fixes the shift fork shaft.

[0004] During the clamping and fixing process of the shift fork, the operator needs to manually adjust the working state of the cylinder, which results in a long clamping and fixing time for the shift fork shaft, leading to low processing efficiency of the shift fork. Summary of the Invention

[0005] In order to improve the processing efficiency of shift forks, this application provides a clamping device for processing shift forks.

[0006] This application provides a clamping device for machining shift forks, which adopts the following technical solution:

[0007] A clamping device for machining shift forks includes a worktable, a mounting plate disposed on the worktable for placing shift forks, a clamping assembly disposed on the worktable for pressing the shift forks on the mounting plate, and a transmission assembly disposed on the mounting plate for adjusting the working state of the clamping assembly under the drive of the shift forks being placed downward.

[0008] By adopting the above technical solution, the shift fork is placed on the mounting plate. During the placement of the shift fork, the transmission component drives the clamping component to start working. After the shift fork is placed on the mounting plate, the clamping component simultaneously completes the fixation of the shift fork, reducing the time required for fixing the shift fork and thus improving the processing efficiency of the shift fork.

[0009] Optionally, the clamping assembly includes a bracket fixedly mounted on the workbench, a pressure plate hinged to the bracket with its hinge axis parallel to the shift fork shaft, and a clamping telescopic rod vertically mounted with its top end slidably connected to the side of the pressure plate away from the shift fork shaft. The bottom end of the clamping telescopic rod is fixedly connected to the workbench, and a transmission assembly is used to drive the pressure plate to rotate.

[0010] By adopting the above technical solution, the transmission component drives the pressure plate to rotate, so that the pressure plate can press and fix the shift fork on the worktable. After the shift fork is processed and removed, the transmission component drives the pressure plate to rotate in the opposite direction to reset.

[0011] Optionally, the top surface of the mounting plate is provided with a placement groove for placing the shift fork shaft; the transmission assembly includes a transmission telescopic rod vertically disposed in the mounting plate, a transmission spring vertically disposed in the fixed end of the transmission telescopic rod and always in a compressed state, and a guide pipe connecting the fixed end of the transmission telescopic rod and the fixed end of the pressing telescopic rod. The movable end of the transmission telescopic rod is slidably connected to the mounting plate in the vertical direction, and the movable end of the transmission telescopic rod can slide into the placement groove; fluid is pre-filled in the fixed end of the transmission telescopic rod.

[0012] By adopting the above technical solution, during the placement of the shift fork shaft, the shift fork shaft presses the movable end of the transmission telescopic rod downward, causing the movable end of the transmission telescopic rod to move downward. This allows the fluid in the fixed end of the transmission telescopic rod to enter the fixed end of the pressing telescopic rod through the guide pipe, causing the movable end of the pressing telescopic rod to move upward under the support of the fluid. This allows the pressure plate to press and fix the shift fork shaft.

[0013] Optionally, an installation groove is provided on the inner side wall of the fixed end of the transmission telescopic rod; the transmission assembly also includes a slider fixedly disposed at the top of the transmission spring, the slider being slidably disposed in the fixed end of the transmission telescopic rod in the vertical direction; a snap-fit ​​component is provided in the installation groove, the snap-fit ​​component is used to position the slider when the slider moves downward to a preset position; a delay component is provided on the slider to drive the snap-fit ​​component to lose its positioning function on the slider; the fluid is located above the slider.

[0014] By adopting the above technical solution, during the vertical downward movement of the movable end of the transmission telescopic rod, the fluid squeezes the slider downward. When the shift fork shaft is placed in the placement groove, the slider moves downward to the preset position under the drive of the fluid. At this time, the locking component fixes the position of the slider. After a preset time, the delay component causes the locking component to lose its fixing effect on the slider, causing the slider to move upward under the action of the transmission spring. This causes the fluid to push the movable end of the transmission telescopic rod upward, thereby restoring the clamping component to the initial state and causing the shift fork shaft to be pushed out.

[0015] Optionally, the slider has a slot that can be positioned directly opposite the mounting groove; the snap-fit ​​assembly includes a snap-fit ​​block that is slidably disposed in the mounting groove and a snap-fit ​​spring that is fixedly disposed between the snap-fit ​​block and the bottom surface of the mounting groove. The snap-fit ​​spring is always in a compressed state, and the snap-fit ​​block is used to enter the slot under the drive of the snap-fit ​​spring.

[0016] By adopting the above technical solution, when the card slot and the mounting slot are set opposite each other, the card block enters the card slot under the action of the card spring, so that the slider is fixed in the vertical position.

[0017] Optionally, the delay component is disposed within the card slot. The delay component includes a magnet fixedly disposed on the bottom surface of the card slot and a telescopic baffle vertically disposed on the side of the magnetic strip away from the bottom surface of the card slot. The fixed end of the telescopic baffle is fixedly connected to the slider, and the movable end of the telescopic baffle is slidably connected to the side wall of the card slot in the vertical direction. There is a mutual repulsive force between the magnet and the card block. When the bottom surface of the movable end of the telescopic baffle abuts against the side wall of the card slot, the repulsive effect of the magnet on the card block disappears. A driving component for extending and retracting the telescopic baffle is disposed within the card slot.

[0018] By adopting the above technical solution, after the card block enters the card slot, the driving component drives the movable end of the telescopic baffle to move upward, so that the magnet repels the card block, thereby causing the card block to move towards the mounting slot; during the movement of the card block in the card slot, the slider position remains fixed, so that the shift fork shaft can be clamped and fixed by the pressure plate for a preset time.

[0019] Optionally, the driving component is slidably inserted into the fixed end of the telescopic baffle along the sliding direction of the card block, and the driving component is always located below the top surface of the movable end of the telescopic baffle. The fixed end of the telescopic baffle is pre-filled with fluid, and the fluid in the fixed end of the telescopic baffle is located below the top surface of the movable end of the telescopic baffle.

[0020] By adopting the above technical solution, during the process of the card block entering the card slot, the card block pushes the driving component away from the mounting slot, so that the space occupied by the driving component in the fixed end of the telescopic baffle gradually increases, thereby causing the fluid in the fixed end of the telescopic baffle to push the movable end of the telescopic baffle upward; when the card block approaches the mounting slot, the movable end of the telescopic baffle squeezes the fluid in the fixed end of the telescopic baffle downward by its own gravity, so that the fluid in the fixed end of the telescopic baffle pushes the driving component, thereby causing the driving component to move towards the mounting slot.

[0021] Optionally, a gasket is fixedly installed on the bottom surface of the pressure plate near the mounting plate.

[0022] By adopting the above technical solution, the setting of the gasket can avoid direct compression between the pressure plate and the shift fork shaft, thus protecting the shift fork shaft.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up a transmission component and a clamping component, the shift fork is placed on the mounting plate. During the placement of the shift fork, the transmission component drives the clamping component to start working. After the shift fork is placed on the mounting plate, the clamping component simultaneously completes the fixation of the shift fork, reducing the time required for fixing the shift fork and thus improving the processing efficiency of the shift fork.

[0025] 2. By setting a driving component, after the card block enters the card slot, the driving component drives the movable end of the telescopic baffle to move upward, so that the magnet repels the card block, and thus the card block moves towards the mounting slot; during the movement of the card block in the card slot, the slider position remains fixed, so that the shift fork shaft can be clamped and fixed by the pressure plate for a preset time.

[0038] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0039] This application discloses a clamping device for machining shift forks. (Refer to...) Figure 1 and Figure 2 A clamping device for processing shift forks includes a horizontally arranged worktable 1, a mounting plate 2 fixedly arranged on the top surface of the worktable 1 for placing shift forks, a clamping assembly 3 arranged on the top surface of the worktable 1 for pressing the shift forks on the mounting plate 2, and a transmission assembly 4 arranged on the mounting plate 2 for adjusting the working state of the clamping assembly 3 under the drive of the shift forks being placed downward.

[0040] When processing the shift fork, the shift fork is first placed on the mounting plate 2. During the placement of the shift fork, the transmission component 4 drives the clamping component 3 to work, so that the clamping component 3 begins to clamp the shift fork. When the shift fork is placed on the mounting plate 2, the clamping component 3 completes the clamping and fixing of the shift fork.

[0041] Reference Figure 1 and Figure 2 Mounting plates 2 are vertically arranged, and two mounting plates 2 are arranged along the length of the worktable 1. A placement groove 21 for placing the shift fork shaft 8 is provided on the top surface of the mounting plate 2, and the inner wall of the placement groove 21 is fitted to the surface of the shift fork shaft 8. Two clamping assemblies 3 are provided, corresponding one-to-one with the mounting plates 2. Each clamping assembly 3 includes a bracket 31, a pressure plate 32, and a clamping telescopic rod 33. The bracket 31 is vertically arranged and fixedly connected to the worktable 1. The pressure plate 32 is positioned above the bracket 31, and the length of the pressure plate 32 is... The center is hinged at the top of the bracket 31, and the hinge axis is the same as the length direction of the worktable 1; the clamping telescopic rod 33 is vertically set on the side of the bracket 31 away from the mounting plate 2 and located below the pressure plate 32. The movable end of the clamping telescopic rod 33 is slidably connected to the end of the pressure plate 32 away from the mounting plate 2 along the length direction of the pressure plate 32, and the fixed end of the clamping telescopic rod 33 is fixedly connected to the worktable 1; a shim 321 is fixedly set on the bottom surface of the pressure plate 32 near the shift fork shaft 8. The shim 321 is made of flexible material.

[0042] Reference Figure 1 and Figure 2 Two transmission components 4 are provided, each corresponding to a mounting plate 2. Each transmission component 4 includes a transmission telescopic rod 41, a slider 42, a transmission spring 43, and a guide tube 44. The transmission telescopic rod 41 is vertically mounted within the corresponding mounting plate 2, with its fixed end fixedly connected to the mounting plate 2 and its movable end slidingly connected to the mounting plate 2 in the vertical direction, extending into the placement groove 21. The slider 42 is slidably mounted within the fixed end of the transmission telescopic rod 41 in the vertical direction, completely abutting against the inner wall of the fixed end of the transmission telescopic rod 41. The transmission spring 43 is vertically mounted within the transmission telescopic rod... The transmission spring 43 is fixedly connected to the top of the slider 42 and the bottom of the transmission telescopic rod 41. Fluid is pre-filled inside the fixed end of the transmission telescopic rod 41, and the fluid is always above the slider 42. One end of the guide tube 44 is connected to the inside of the fixed end of the transmission telescopic rod 41, and the other end is connected to the inside of the fixed end of the pressing telescopic rod 33. The connection between the guide tube 44 and the fixed end of the transmission telescopic rod 41 is located between the slider 42 and the movable end of the transmission telescopic rod 41. The connection between the guide tube 44 and the fixed end of the pressing telescopic rod 33 is located below the movable end of the pressing telescopic rod 33.

[0043] Reference Figure 2 and Figure 3The transmission telescopic rod 41 has an installation groove 411 on the inner side wall of the fixed end; the slider 42 has a slot 421 on the side near the installation groove 411 that can be directly opposite the installation groove 411; the installation groove 411 is provided with a snap-fit ​​assembly 7, which includes a snap-fit ​​spring 71 and a snap-fit ​​block 72, wherein the snap-fit ​​block 72 is slidably disposed in the installation groove 411; the snap-fit ​​spring 71 is horizontally disposed in the installation groove 411 and is fixedly disposed between the bottom surface of the installation groove 411 and the snap-fit ​​block 72, and the snap-fit ​​spring 71 is always in a compressed state, and the snap-fit ​​spring 71 can drive one end of the snap-fit ​​block 72 to slide into the slot 421.

[0044] Reference Figure 2 and Figure 3 A delay component 5 is provided in the card slot 421. The delay component 5 includes a magnet 51 and a telescopic baffle 52. The magnet 51 is vertically disposed at the bottom of the card slot 421 and is fixedly connected to the bottom surface of the card slot 421. The telescopic baffle 52 is vertically disposed on the side of the magnet 51 away from the bottom surface of the card slot 421. The fixed end of the telescopic baffle 52 is fixedly connected to the side wall of the card slot 421, and the bottom surface of the movable end of the telescopic baffle 52 can abut against the bottom surface of the card slot 421. When the bottom surface of the movable end of the telescopic baffle 52 abuts against the side wall of the card slot 421, the telescopic baffle 52 isolates the repulsive effect of the magnet 51 on the card block 72. A driving component 6 is horizontally inserted on the side of the fixed end of the telescopic baffle 52 away from the magnet 51. The driving component 6 is slidably connected to the telescopic baffle 52 along the sliding direction of the card block 72.

[0045] First, the shift fork shaft 8 is placed horizontally in the two placement slots 21. Under the action of external force, the shift fork shaft 8 moves vertically downward into the placement slot 21. During the process of the shift fork shaft 8 entering the placement slot 21, the shift fork shaft 8 presses down on the movable end of the transmission telescopic rod 41, causing the movable end of the transmission telescopic rod 41 to move downward. During the downward movement of the movable end of the transmission telescopic rod 41, the fluid in the fixed end of the transmission telescopic rod 41 is squeezed, causing the slider 42 to move downward under the squeezing action of the fluid. At the same time, the fluid enters the fixed end of the pressing telescopic rod 33 through the guide pipe 44.

[0046] The fluid entering the fixed end of the clamping telescopic rod 33 pushes the movable end of the clamping telescopic rod 33 upward, causing the pressure plate 32 to press against the shift fork shaft 8. When the shift fork is placed in the placement groove 21, the slider 42 descends to the preset position. When the slider 42 descends to the preset position, the mounting groove 411 and the slot 421 are aligned, allowing the locking block 72 to enter the slot 421 under the action of the locking spring 71, thereby fixing the position of the slider 42. During the process of the locking block 72 entering the slot 421, it pushes the driving component 6 into the telescopic baffle 52, causing the fluid in the fixed end of the telescopic baffle 52 to push the movable end of the telescopic baffle 52 upward, thereby causing the magnet 51 to repel the locking block 72, and thus allowing the locking block 72 to detach from the slot 421 and enter the mounting groove 411 under the repulsive action of the magnet 51.

[0047] When the locking block 72 disengages from the slot 421, the slider 42 loses its vertical limiting function, causing the compressed transmission spring 43 to push the slider 42 upward. During the upward movement, the slider 42 can push the movable end of the transmission telescopic rod 41 upward through the fluid in the fixed end of the transmission telescopic rod 41, causing the shift fork shaft 8 to be pushed out by the movable end of the transmission telescopic rod 41. During the upward movement of the slider 42, the movable end of the pressing telescopic rod 33 can use its own gravity to squeeze the fluid in the fixed end of the pressing telescopic rod 33 through the guide pipe 44 into the fixed end of the transmission telescopic rod 41.

[0048] The implementation principle of the clamping device for processing shift forks in this application embodiment is as follows: the shift fork is placed on the mounting plate 2. During the placement of the shift fork, the transmission component 4 drives the clamping component 3 to start working. After the shift fork is placed on the mounting plate 2, the clamping component 3 simultaneously completes the fixing of the shift fork, reducing the time required for fixing the shift fork, thereby improving the processing efficiency of the shift fork.

[0049] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
