Description

Technical Field

[0001] This utility model relates to the field of turning equipment technology, specifically to an engine cylinder liner turning mechanism. Background Technology

[0002] Engine cylinder liners, also known as cylinder liners, are part of the engine cylinder block. They are cylindrical components installed inside the engine cylinder and are usually made of wear-resistant alloy cast iron or other metal materials. During the production and processing of cylinder liners, they need to be machined using a turning device.

[0003] A search revealed Chinese patent application CN202321421625.6, which proposes a turning mechanism for engine cylinder liner production. The mechanism includes a machine tool, a guide column, and a chuck. The machine tool is mounted on external equipment, the chuck is connected to the machine tool, and the guide column is mounted on the machine tool. The machine tool is equipped with an integration mechanism and a positioning mechanism. The integration mechanism includes a moving table, a first transverse block, a second transverse block, a tool holder block, a flat cutting tool, a beveling mechanism, and an internal cutting mechanism. The moving table is slidably connected to the guide column, and the first and second transverse blocks are slidably connected to the moving table. This integration mechanism, by integrating multiple cutting tools and mechanisms, solves the problem of frequent tool and machine tool changes required during cylinder liner machining, thereby improving production efficiency and machining accuracy.

[0004] In the aforementioned prior art, the cutter is quickly installed by the threaded engagement of the lead screw and the extension rod. Although this threaded engagement method can achieve the effect of quick disassembly and replacement, in actual use, the threaded engagement method will cause shaking due to the rapid rotation of the parts at the contact point between the cutter and the workpiece. This will cause the threads to loosen, resulting in the position of the cutter shifting and causing large deviations in the turning dimensions, or the cutter falling off, thus affecting the undoing efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide an engine cylinder liner turning mechanism, which solves the problem that in the existing engine cylinder liner turning mechanism, when the cutter is installed by bolt engagement, the cutter is prone to loosening or falling off due to the friction generated during the turning process.

[0006] This utility model provides the following technical solution: an engine cylinder liner turning mechanism, including a base, a control box fixedly connected to one end of the base, and a bracket fixedly connected to the upper side of the end of the base near the control box.

The two ends of the positioning rods are respectively fixed to the bracket and the chuck. A replacement assembly is provided on the upper end of the movable seat. The replacement assembly includes a second motor installed on one side of the upper end of the movable seat, and a cylinder is fixedly connected to the output shaft of the second motor. The end of the cylinder near the second motor is rotatably connected to the movable seat, and a turntable is fixedly connected to the end of the cylinder away from the second motor. A first threaded cylinder is fixedly connected to the outer side of the turntable.

[0008] As a preferred embodiment of the above technical solution, a cutter is inserted inside the end of the first threaded cylinder away from the turntable, and a locking block is fixedly connected to the end of the cutter inserted inside the first threaded cylinder.

[0009] The above technical solution involves setting multiple sets of locking blocks at one end of the cutter, which facilitates subsequent blocking blocks to counteract the locking blocks.

[0010] As a preferred embodiment of the above technical solution, the end of the card block away from the turntable is attached to a stop block, and the end of the stop block away from the card block is fixedly connected to a connecting plate, and the end of the connecting plate away from the stop block is rotatably connected to a second threaded cylinder.

[0011] The above technical solution utilizes multiple sets of blocking blocks to restrict the blocking position of the blocks.

[0012] As a preferred embodiment of the above technical solution, the inner side of the second threaded cylinder is threadedly engaged with the first threaded cylinder, and the four sets of abutments abut against the four sets of locking blocks one by one.

[0015] The above technical solution utilizes the elastic potential energy of the spring to push the first insert rod into the second threaded cylinder.

[0016] As a preferred embodiment of the above technical solution, the end of the connecting ring near the second threaded cylinder is fixedly connected to a first insert rod, and the ends of the two sets of first insert rods away from the connecting ring are inserted into the second threaded cylinder.

[0017] The above technical solution allows for the locking and restraint of the second threaded cylinder by inserting the first insert rod into it.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figure 1 - Figure 4As shown, this utility model provides a technical solution: an engine cylinder liner turning mechanism, including a base 1, a control box 11 fixedly connected to one end of the base 1, and a bracket 12 fixedly connected to the upper side of the end of the base 1 near the control box 11. A first motor 13 is installed on one side of the bracket 12, and a threaded rod 14 is fixedly connected to the output shaft of the first motor 13. A movable seat 15 is threadedly engaged on the outer side of the middle end of the threaded rod 14, and a chuck 16 is rotatably connected to the end of the threaded rod 14 away from the bracket 12. The lower end of the chuck 16 is fixedly connected to the base 1, and positioning rods 17 are inserted inside both ends of the movable seat 15. The two ends of the positioning rods 17 are respectively... The replacement component 2 is fixed on the bracket 12 and chuck 16, and the upper end of the movable seat 15 is provided with a replacement component 2. The replacement component 2 includes a second motor 21 installed on one side of the upper end of the movable seat 15, and a cylinder 22 is fixedly connected to the output shaft of the second motor 21. The end of the cylinder 22 close to the second motor 21 is rotatably connected to the movable seat 15, and the end of the cylinder 22 away from the second motor 21 is fixedly connected to a turntable 23. A first threaded cylinder 24 is fixedly connected to the outside of the turntable 23. This allows for quick disassembly and removal of the cutter 25, while also improving the stability after installation, preventing the cutter 25 from loosening due to turning vibration, and thus improving turning efficiency.

[0028] like Figure 4 As shown, a cutter 25 is inserted into the end of the first threaded cylinder 24 away from the turntable 23, and a locking block 26 is fixedly connected to the end of the cutter 25 inserted into the first threaded cylinder 24. The cutter 25 drives the locking block 26 to be inserted into the first threaded cylinder 24, and the cutter 25 is initially positioned.

[0029] like Figure 4 As shown, the end of the locking block 26 away from the turntable 23 is attached to the abutment 27, and the end of the abutment 27 away from the locking block 26 is fixedly connected to the connecting plate 28. The end of the connecting plate 28 away from the abutment 27 is rotatably connected to the second threaded cylinder 29. By utilizing the threaded engagement between the second threaded cylinder 29 and the first threaded cylinder 24, the connecting plate 28 and the abutment 27 can be moved, allowing the abutment 27 to press against the locking block 26.

[0030] like Figure 4 As shown, the inner side of the second threaded cylinder 29 is threadedly engaged with the first threaded cylinder 24, and the four sets of abutments 27 abut against the four sets of locking blocks 26 one by one. The abutments 27 press against the locking blocks 26 to restrict their positioning.

[0031] like Figure 4 As shown, a connecting ring 210 is provided at the end of the second threaded cylinder 29 away from the connecting plate 28, and a spring 211 is fixedly connected to the end of the connecting ring 210 away from the second threaded cylinder 29. The end of the spring 211 away from the connecting ring 210 is fixedly connected to the turntable 23. Pulling the connecting ring 210 causes the first insert rod 212 to move and compress the spring 211.

[0032] like Figure 4 As shown, a first insert rod 212 is fixedly connected to one end of the connecting ring 210 near the second threaded cylinder 29, and the ends of the two sets of first insert rods 212 away from the connecting ring 210 are inserted into the second threaded cylinder 29. The first insert rods 212 are inserted into the second threaded cylinder 29 to lock and restrict the second threaded cylinder 29.

[0033] like Figure 4 As shown, a second insert rod 213 is inserted into the inner side of the spring 211, and the end of the second insert rod 213 near the connecting ring 210 is fixedly connected to the connecting ring 210. A fixing cylinder 214 is sleeved on the outer side of the end of the second insert rod 213 away from the connecting ring 210, and the end of the fixing cylinder 214 away from the second insert rod 213 is fixedly connected to the turntable 23. By inserting the second insert rod 213 and the fixing cylinder 214, the movement of the connecting ring 210 can be restricted.

[0034] Working principle: When installing and using the cutter 25, first insert the cutter 25 and the locking block 26 into the first threaded cylinder 24. Then, move the connecting plate 28 and the abutment 27 around the outside of the cutter 25. At the same time, simultaneously turn the second threaded cylinder 29. The second threaded cylinder 29 moves by engaging with the first threaded cylinder 24. During the engagement of the second threaded cylinder 29 with the first threaded cylinder 24, the abutment 27 is inserted into the first threaded cylinder 24 to press the locking block 26. When the second threaded cylinder 29 is about to be fully turned, first pull the connecting ring 210. After the connecting ring 210 is pulled, it moves and compresses the spring 211 with the assistance of the second insert rod 213 and the fixed cylinder 214. Then, when the second threaded cylinder 29 is fully turned, release the pressed connecting ring 210. At this time, the elasticity of the spring 211 helps to release the spring. Potential energy drives the first insert rod 212 into the second threaded cylinder 29 for locking. When removing it later, first pull the connecting ring 210 to pull the first insert rod 212 out of the second threaded cylinder 29, then twist the second threaded cylinder 29 in the opposite direction to push the connecting plate 28 and the stop block 27 away from the first threaded cylinder 24. Finally, pull the cutter 25 to drive the stop block 26 to pull out the first threaded cylinder 24. When using the cutter 25 to process the cylinder liner, the operation of the first motor 13 drives the threaded rod 14 to rotate. The threaded engagement between the threaded rod 14 and the moving seat 15 allows the moving seat 15 to move and adjust. At the same time, the operation of the second motor 21 drives the cylinder 22 and the turntable 23 to rotate and adjust. Different cutters 25 can then be used to process the cylinder liner. The position of the cutter 25 can be adjusted by the extension and retraction of the cylinder 22.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
