Abstract

The invention discloses a connecting rod big end hole integral machining device. The connecting rod big end hole integral machining device comprises a boring tool bit and a connecting rod positioningmechanism, and further comprises a bottom plate and a working cylinder used for driving the connecting rod positioning mechanism to move relative to the boring tool bit. The connecting rod positioningmechanism and the working cylinder are both arranged on the bottom plate. The connecting rod positioning mechanism is connected with a piston rod of the working cylinder. The connecting rod positioning mechanism comprises a hydraulic cylinder, a fixed plate and a baffle. The baffle is arranged between the fixed plate and the boring tool bit. The baffle is provided with a receding through hole corresponding to the boring tool bit. The fixed plate is located between the hydraulic cylinder and the baffle. A movable pressing block used for pressing the big end of a connecting rod body and a connecting rod cover onto the baffle is arranged in the position, corresponding to the receding through hole, of the fixed plate. The movable pressing block is arranged corresponding to a piston head of the hydraulic cylinder. The connecting rod big end hole integral machining device can conduct integral one-time machining on a connecting rod big end hole. The product quality is improved. The overall machining efficiency is substantially improved.

Example Embodiment

[0022] With reference to the accompanying drawings, the specific implementation of the present invention will be further described in detail through the description of the embodiments.
[0023] Such as figure 1 with figure 2 As shown, the overall processing device for the connecting rod large-end hole includes a boring cutter head 1, a bottom plate 2, a sliding plate 3, a support plate 4, a hydraulic cylinder 5, a piston head 6, a fixed plate 7, a top post 8, a top block 9, The connecting rod small-end positioning column 10, the movable pressing block 11, the baffle 12, the top plate 13, the pressing rod 14, the blowing pipe 16, the supporting rod 17, and the working cylinder 18.
[0024] The bottom plate 2 is provided with a connecting rod positioning mechanism for fixing the connecting rod body and the connecting rod cover, and a boring machine for boring large-end holes of the connecting rod, and a boring cutter head 1 is provided on the boring machine.
[0025] The boring machine and the connecting rod positioning mechanism are arranged relative to each other. Specific examples of the connecting rod positioning mechanism will be described in detail below with reference to the drawings.
[0026] The sliding plate 3 is movably arranged on the bottom plate 2. The bottom plate is provided with a guide rail for the sliding plate to move along the axis of the boring cutter head. The bottom plate is provided with a working cylinder or motor for driving the sliding plate to move, and the sliding plate is arranged on the guide rail. , The sliding plate is connected with the piston rod of the working cylinder; after the connecting rod body and the connecting rod cover are positioned simultaneously by the connecting rod positioning mechanism, the working cylinder drives the sliding plate to move relative to the boring cutter head.
[0027] The support plate 4 and the fixed plate 7 are fixed side by side on the sliding plate. There is a certain gap between the support plate and the fixed plate. The baffle plate is arranged on the fixed plate. The baffle plate is located between the fixed plate and the boring cutter head. The upper corresponding boring cutter head is provided with an avoidance through hole 15.
[0028] The hydraulic cylinder 5 is arranged on the support plate 4, and the fixed plate is located between the hydraulic cylinder and the baffle plate. The corresponding escape through hole in the fixed plate is provided with movable pressure for pressing the big end of the connecting rod body and the connecting rod cover on the baffle plate. Block 11, the movable pressing block 11 is arranged corresponding to the piston head 6 of the hydraulic cylinder. The movable pressing block can be driven by the hydraulic cylinder to press the big end of the connecting rod body and the connecting rod cover on the baffle, and the big end hole part of the connecting rod body and the connecting rod cover that are paired together by the boring cutter head is processed simultaneously.
[0029] Alternatively, the support plate 4 is arranged on the fixed plate by bolts, and the baffle 12 is directly fixed on the sliding plate, and rotates according to the needs of the production site.
[0030] The fixing plate 7 is provided with a connecting rod small head positioning column 10 on the side of the boring cutter head, and the small head hole on the connecting rod body is directly sleeved on the connecting rod small head positioning column for positioning to ensure the accuracy of installation and positioning.
[0031] The connecting rod small-end positioning column 10 includes a sleeve, a pressing plate and a positioning bolt, and the sleeve is detachably arranged on the fixing plate through the pressing plate and the positioning bolt. The outer diameter of the sleeve can be changed according to different connecting rod models, so that different types of connecting rods can be processed.
[0032] The top of the fixed plate 7 is provided with a top plate 13, and the baffle can be fixed to the fixed plate through the top plate; or the baffle is installed on the fixed plate by bolts, and the bolt part between the baffle and the fixed plate is sleeved with a gasket. Different cushion cylinders adjust the gap between the fixed plate and the baffle to meet the requirements of different types of connecting rod processing.
[0033] The top plate 13 is provided with a pressing rod 14 for pressing the connecting rod cover. The top plate is provided with a threaded hole. The pressing rod includes a handle and a threaded rod. The threaded rod is set in the threaded hole of the top plate, and the handle is set on the top of the threaded rod. , The connecting rod cover is pressed tightly on the connecting rod body through the pressing rod to ensure the matching effect between the connecting rod body and the connecting rod cover, and the pressing rod can be adjusted up and down to adapt to different types of connecting rods.
[0034] The fixed plate 7 is provided with a through hole corresponding to the boring cutter head, the movable pressing block 11 is connected with 9 top blocks, and the movable pressing block and the top block are connected by a connecting column, and the pressing block and the top block are both ring structures, or The two semicircular rings are combined into a circular ring structure. The center hole of the pressing block and the top block so as to avoid the boring cutter head.
[0035] The movable pressure block and the top block are combined and arranged in the through hole of the fixed plate, and the top block is opposite to the piston head. The connecting column passes through a guide hole provided on the fixing plate, and a spring is sleeved on the connecting column part between the top block and the fixing plate. The top block is provided with a set of top posts 8 corresponding to the piston head.
[0036] The hydraulic cylinder drives the top block and the pressure block to press and position the connecting rod body and the connecting rod cover together on the baffle, and drive the sliding plate to slide, so as to realize the big end of the connecting rod body and the connecting rod cover that are aligned with the boring cutter head. Hole processing; and in the baffle 12 corresponding to the avoidance through hole is provided with a blowing pipe 16 for blowing iron filings, the blowing pipe is set on the supporting rod 17 on the baffle, the supporting rod 17 can be rotated and adjusted to adjust the blowing of the blowing pipe Air angle to ensure processing quality.
[0037] The present invention has been exemplarily described above with reference to the accompanying drawings.
