Description

Technical Field

[0001] The utility model relates to the technical field of shift fork processing, in particular to a shift fork positioning and punching device. Background Art

[0002] In automobiles, the shift fork is a key component of the gearbox. It is connected to the shift handle and is usually located at the lower end of the handle. The main function of the shift fork is to change the input and output speed ratio to achieve speed change. It realizes the engagement and separation of each forward gear by shifting the synchronizer ring. In the reverse gear shift, since there is no synchronizer, the shift fork directly shifts the reverse gear to switch the reverse gear. Since the shift fork and the shift lever are connected through a hole, the shift fork needs to be punched during the processing process, and a punching device is required. When punching the shift fork, the shift fork needs to be placed under the punching machine first. In order to prevent the shift fork from moving during the punching and causing damage to the punching machine and the shift fork, the shift fork needs to be fixed. The transmission fixing method is mostly to fix the shift fork with a clamp, so that after the processing is completed, the clamp needs to be opened and the shift fork needs to be taken out before it can be processed again. In actual use, a lot of time will be wasted in the process of loading and unloading, thus affecting the processing efficiency.

Since there is no stop plate on one side of the pawl 27, the ratchet 26 drives the pawl 27 to rotate, and the first transmission shaft does not rotate. Then the push rod 18 pushes the clamping mold 15 to move, and the first transmission shaft drives the first one-way friction wheel 23 and the second one-way friction wheel 25 to move, so that the second one-way friction wheel 25 is separated from the second friction wheel plate 24. When the punching component 11 finishes punching the shift fork and returns to the initial position, the push rod 18 first separates from the clamping mold 15, and the clamping mold 15 returns to the initial position under the action of the reset spring 19. Then the second friction wheel plate 24 contacts with the second one-way friction wheel 25, and the second friction wheel plate 24 moves. When the pawl 27 moves, the second one-way friction wheel 25 is driven to rotate. Since a stop plate is provided on one side of the pawl 27, the second one-way friction wheel 25 drives the first transmission shaft to rotate, and the first transmission shaft drives the first one-way friction wheel 23 to rotate. The first one-way friction wheel 23 and the first friction plate 22 are frictionally matched, so that the first friction plate 22 drives the sliding baffle 20 to slide. When the sliding baffle 20 is separated from the shift fork, the shift fork falls on the upper end of the transmission belt 29, and then the second friction wheel plate 24 is separated from the second one-way friction wheel 25. Under the action of the tension spring 21, the sliding baffle 20 returns to the initial position, so that the first one-way friction wheel 23 rotates in the opposite direction.

When in use, when the first transmission shaft rotates, the first transmission shaft drives the first friction wheel to rotate, the first friction wheel drives the second transmission shaft 34 to rotate through the second friction wheel 33, and the second transmission shaft 34 drives the transmission belt 29 to rotate through the first belt, thereby transmitting the shift fork at the upper end of the transmission belt 29.

[0031] The cleaning mechanism includes a cleaning tube 31, and the cleaning tube 31 is fixedly installed at the upper end and the inner side of the installation perforation corresponding to the upper end of the conveyor belt 29 and the lower end of the inner side of the conveyor belt 29 respectively.

Since the conveyor belt 29 is provided with a plurality of circular perforations, the debris falls into the collection box 30. Then the conveyor belt 29 drives the shift fork to move. When the shift fork moves to the corresponding position of the cleaning tube 31, the output end of the fan 32 delivers air to the inside of the cleaning tube 31, and the cleaning tube 31 discharges the air through a plurality of air outlets, thereby blowing off the debris on the shift fork and the conveyor belt 29. Then, when the conveyor belt 29 rotates to the bottom end of the cleaning tube 31 located on the inner side of the conveyor belt 29, the cleaning tube 31 can back-blow the circular perforations on the conveyor belt 29, thereby causing the debris stuck in the circular perforations to fall off.

[0035] The above embodiment discloses a shift fork positioning and punching device, wherein when the shift fork needs to be punched, the shift fork is placed on the upper end of the sliding baffle 20, and then the punching component 11 and the hydraulic cylinder 12 are started. The output end of the hydraulic cylinder 12 drives a plurality of punching components 11 to move through the connecting plate. Before the punching component 11 contacts the shift fork, the second friction wheel plate 24 first contacts the second unidirectional friction wheel 25. Since there is no stop plate on one side of the pawl 27, the ratchet 26 drives the pawl 27 to rotate, and the first transmission shaft does not rotate. Then, one end of the push rod 18 is in close contact with the inclined surface of the guide block 17. As the output end of the hydraulic cylinder 12 continues to move, the push rod 18 pushes the two clamping molds 15. When one side of the push rod 18 is in close contact with one side of the guide block 17, one side of the two clamping molds 15 The first one-way friction wheel 23 and the second one-way friction wheel 25 are tightly attached to each other, thereby clamping and fixing the shift fork, and the first transmission shaft drives the first one-way friction wheel 23 and the second one-way friction wheel 25 to move, so that the second one-way friction wheel 25 is separated from the second friction wheel plate 24, and then the punching component 11 punches holes in the shift fork. When the punching component 11 finishes punching holes in the shift fork and returns to the initial position, the push rod 18 first separates from the clamping mold 15, and the clamping mold 15 returns to the initial position under the action of the reset spring 19, and then the second friction wheel plate 24 contacts the second one-way friction wheel 25.

Then the second friction wheel plate 24 is separated from the second one-way friction wheel 25. Under the action of the tension spring 21, the sliding baffle 20 returns to the initial position, so that the first one-way friction wheel 23 rotates in the opposite direction. Since there is no stop plate on one side of the pawl 27, the first one-way friction wheel 23 does not drive the first transmission shaft to rotate. When the shift fork falls on the upper end of the transmission belt 29, since the transmission belt 29 is made of flexible material, the shift fork bounces slightly on the upper end of the transmission belt 29, so that the debris on the transmission belt 29 is separated from the upper end of the transmission belt 29. Since the transmission belt 29 is provided with a plurality of circular perforations , so that the debris falls into the collection box 30, and then the conveyor belt 29 drives the fork to move. When the fork moves to the corresponding position of the cleaning tube 31, the output end of the fan 32 conveys air to the inside of the cleaning tube 31, and the cleaning tube 31 discharges air through a plurality of air outlets, thereby blowing off the debris on the fork and the conveyor belt 29. Then, when the conveyor belt 29 rotates to the bottom end of the cleaning tube 31 located on the inner side of the conveyor belt 29, the cleaning tube 31 can back-blow the circular perforations on the conveyor belt 29, so that the debris stuck in the circular perforations falls off. At the same time, when the first transmission shaft rotates, the first transmission shaft drives the first friction wheel to rotate, and the first friction wheel drives the second transmission shaft 34 to rotate through the second friction wheel 33, and the second transmission shaft 34 drives the conveyor belt 29 to rotate through the first belt.Thereby, the upper end fork of the conveyor belt 29 is transmitted.
