Description

Technical Field

[0001] This utility model relates to the field of long shaft deep hole machining technology, and in particular to a long shaft deep hole forging machining device. Background Technology

[0002] Long shaft deep holes refer to holes with a depth-to-diameter ratio greater than 10. They are commonly found in precision mechanical parts such as cylinder bores and axial oil holes. Long shaft deep hole forging processing equipment is a special equipment used to process deep holes in long shaft parts. It is a professional equipment designed specifically for long shaft parts. When processing long shaft deep holes, drilling is required. Special drilling equipment is needed to achieve deep hole processing for long shaft forged blanks.

[0003] To address this, patent publication CN209157219U discloses a long-shaft deep-hole machining device, comprising a main frame. Two first bearings are embedded on the left side of the main frame, each housing a gear shaft. Two second bearings are embedded in the middle of the main frame, each housing a shaft with a spacer sleeve and a gear meshing on it. Two bearing sleeves are embedded on the right side of the main frame, each housing a hollow gear shaft, which contains a drill bit. First, external power is input to the gear shaft, and the meshing of the gear shaft and gear changes the transmission ratio. Then, the gear meshes with the hollow gear shaft, and finally, a flat-end set screw transmits power to the drill bit. This device effectively avoids excessively large shoulders on long-shaft parts obstructing hole machining, improving the machining efficiency of such holes and thus increasing the overall production efficiency of long-shaft parts.

[0004] The aforementioned long shaft deep hole machining device can effectively avoid the obstruction of hole machining by excessively large shaft shoulders in long shaft parts, thereby improving the machining efficiency of such holes and thus improving the overall production efficiency of long shaft parts. However, when machining different deep holes, different types of drill bits are required, and different machining processes require different drill bits to be changed. Utility Model Content

[0005] The purpose of this invention is to provide a long-shaft deep-hole forging processing device to solve the defect of existing long-shaft deep-hole forging processing devices that make it difficult to replace drill bits.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a long-shaft deep hole forging processing device, including a housing;

[0007] The bottom of the box is equipped with support legs, the top of the box is equipped with a workbench, and a mounting plate is installed on one side of the top of the workbench. A hydraulic cylinder is installed on one side of the mounting plate.

[0008] A hydraulic rod is mounted on one side of the hydraulic cylinder, a servo motor is mounted on one side of the hydraulic rod, a moving block is mounted on one side of the servo motor, and a rotating shaft is mounted on one side of the moving block.

[0009] A disassembly and assembly structure is installed on one side of the rotating shaft, and a drill bit is installed on one side of the disassembly and assembly structure. The disassembly and assembly structure includes a connecting block installed on one side of the rotating shaft, and a fixing block is engaged inside the connecting block.

[0010] In use, after first limiting the long shaft deep hole, the hydraulic cylinder can drive the hydraulic rod to extend and retract. The extension and retraction of the hydraulic rod can drive the moving block to move. The movement of the moving block can drive the drill bit to move. The servo motor can drive the drill bit to rotate along the rotating shaft. The rotation of the drill bit can perform drilling processing on the long shaft deep hole.

[0011] Furthermore, a limiting structure is installed at the top of the workbench. The limiting structure includes a second limiting plate installed at the top of the workbench, a first limiting plate installed at the top of the second limiting plate, and guide plates installed at both ends of the first limiting plate. A support frame passes through the inside of the guide plate, a fixing plate is installed at the top of the support frame, and a screw passes through the middle of the fixing plate. The limiting structure can limit movement through a long axis deep hole.

[0012] Furthermore, the outer side wall of the screw is uniformly provided with external threads, and the inner side wall of the fixing plate is uniformly provided with internal threads that cooperate with the external threads. The screw and the fixing plate are threadedly connected, and the rotation of the screw can drive the first limiting plate to rise and fall.

[0013] Furthermore, the guide plate and the support frame are configured as a sliding structure, and the guide plate is symmetrically distributed about the central axis of the first limiting plate. The guide plate and the support frame cooperate to guide the first limiting plate.

[0014] Furthermore, a dust collection mechanism is installed on one side of the workbench. The dust collection mechanism includes a bellows installed on one side of the workbench, and a fan is installed on one side of the bellows. A screen is installed inside the bellows, and a duct is installed at the bottom of the bellows. A housing is installed at the bottom of the duct, and a box is installed inside the housing. The dust collection mechanism can adsorb dust.

[0015] Furthermore, the box and the shell form a sliding structure, with the outer diameter of the box being smaller than the inner diameter of the shell, allowing the box to slide inside the shell.

[0016] Furthermore, the bottom end of the movable block is provided with a slider, and the top end of the worktable is provided with a sliding groove. The movable block and the worktable form a sliding structure, and the movable block can slide on the top end of the worktable.

[0017] Furthermore, the outer side of the fixing block is provided with a groove, the inside of the groove is provided with a spring, the outer side of the spring is provided with a buckle, the bottom end of the buckle is provided with a damper, and the outer side of the connecting block is provided with a locking groove. The disassembly and assembly structure can fix the drill bit.

[0018] Furthermore, the spring is helical in shape, and the spring and the buckle form an elastic connection, giving the spring its elasticity.

[0019] The advantages of the long-shaft deep-hole forging processing device provided by this utility model are: during use, the drill bit can be disassembled and replaced through the disassembly and assembly structure, the deep hole during processing can be limited by the limiting structure, and the dust generated during processing can be treated by the dust collection mechanism.

[0020] By installing a connecting block on one side of the shaft, the fixing block on the drill bit side can be inserted into the connecting block. The buckle on the outside of the fixing block can extend and retract inside the groove. One side of the buckle is inclined. When the fixing block is inserted into the connecting block, the buckle will automatically move downward. After the fixing block is fully inserted into the connecting block, the buckle will spring up due to the elasticity of the spring. The buckle can lock the engagement groove and fix the fixing block and the drill bit. When the drill bit needs to be replaced, press the buckle so that it is no longer locked in the engagement groove, and the drill bit can be disassembled for replacement. This achieves the purpose of making it easy to replace the drill bit in the long shaft deep hole forging processing device.

[0021] By installing a support frame at the top of the worktable, and the fixed plate and screw at the top of the support frame forming a threaded connection, the screw can be turned to drive the screw and the first limiting plate at the bottom to rise and fall. The rise and fall of the first limiting plate can clamp the deep hole between the first limiting plate and the second limiting plate. The first limiting plate and the second limiting plate can fix the deep hole. The support frame passes through the guide plate, thereby achieving the purpose of facilitating the limiting of the deep hole in the long shaft deep hole forging processing device.
