Description

Technical Field

[0001] This utility model relates to the field of cylinder liner machining technology, and in particular to a boring bar fixing seat suitable for machining the inner hole of thin-walled cylinder liners. Background Technology

[0002] Thin-walled cylinder liners are a type of cylinder liner with a wall thickness that is thinner than its overall size. They are typically used in internal combustion engines or other mechanical equipment where weight reduction and improved heat transfer efficiency are required.

[0003] Traditional boring bar fixing methods mostly use flanges and bolts for fixation. When the boring bar needs maintenance or replacement, the disassembly process is relatively troublesome, reducing maintenance efficiency. Therefore, this utility model proposes a boring bar fixing seat suitable for machining the inner hole of thin-walled cylinder liners to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the problem that traditional boring bar fixing methods often use flanges and bolts for fixing, which makes the disassembly process cumbersome and reduces maintenance efficiency when the boring bar needs maintenance or replacement. Therefore, this invention proposes a boring bar fixing seat suitable for machining the inner hole of thin-walled cylinder liners.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A boring bar holder suitable for machining the inner bore of thin-walled cylinder liners includes a fixed shell. A first motor is fixedly installed on the left side of the inner cavity of the fixed shell. A sleeve is fixedly installed on the output end of the first motor. The left side of the sleeve penetrates the fixed shell. A boring bar is movably arranged in the inner cavity of the sleeve. The boring bar has insertion holes on both its front and rear sides. The boring bar holder also includes: A positioning mechanism is located on the right side of the inner cavity of the sleeve, and the positioning mechanism is used to fix the boring bar.

[0006] As a preferred embodiment of this utility model, the positioning mechanism includes: a fixed box, a partition, a second motor, a first bevel gear, a second bevel gear, a connecting rod, a turntable, a transmission block, a transmission frame, and a insert plate; The front and rear sides of the sleeve are fixedly connected to the fixed box. The partition is fixedly installed on the right side of the sleeve's inner cavity. The right side of the sleeve is fixedly connected to the second motor. The output shafts of the front and rear sides of the second motor pass through the sleeve and are fixedly connected to the first bevel gear. The left side of the first bevel gear meshes with the second bevel gear. There are two second bevel gears. The left side of the second bevel gear is fixedly connected to the connecting rod. There are two connecting rods. The left side of the connecting rod passes through the inner cavity of the fixed box and is fixedly connected to the turntable. There are two turntables. The left side of the turntable is fixedly connected to the transmission block. There are two transmission blocks. The transmission frame is movably sleeved on the surface of the transmission block. There are two transmission frames. The top and bottom of the transmission frame are slidably connected to the inner wall of the fixed box. The opposite sides of the two transmission frames are fixedly connected to the insertion plate. The opposite sides of the two insertion plates pass through the fixed box and extend into the inner cavity of the insertion port.

[0007] As a preferred embodiment of this utility model, heat dissipation vents are provided at both the top and bottom of the sleeve.

[0008] As a preferred embodiment of this utility model, a positioning groove is provided on the left side of the partition, and a positioning plate is fixedly installed on the right side of the boring bar, with the right side of the positioning plate extending into the inner cavity of the positioning groove.

[0009] As a preferred embodiment of this utility model, each of the two fixing boxes has a positioning port on one side opposite to the other, and the positioning port cooperates with the insert plate.

[0010] As a preferred embodiment of this utility model, a limiting port is provided on the left side of the fixed shell, and the limiting port cooperates with the sleeve.

[0011] As a preferred embodiment of this utility model, guide grooves are provided at the top and bottom of the fixing box, and guide rails are provided at the top and bottom of the transmission frame, with the guide grooves and guide rails cooperating with each other.

[0012] Beneficial effects: 1. The first motor drives the sleeve to rotate for machining. When the boring bar needs to be replaced or maintained, the second motor starts and drives the connecting rod to rotate through the meshing of the first bevel gear and the second bevel gear. The connecting rod pushes the turntable to rotate, and the transmission block on the turntable moves accordingly and pushes the transmission frame to move laterally. The transmission frame drives the insert plate to exit from the boring bar's insertion hole, thus releasing the locking of the boring bar. The operator can directly remove the boring bar axially. The whole process does not require disassembling bolts, which significantly improves maintenance efficiency. In this utility model, the design of the positioning mechanism enables the rapid assembly, disassembly, and fixation of the boring bar, effectively solving the problem of cumbersome disassembly using traditional bolt fixing methods.
