Description

Technical Field

[0001] This utility model relates to the technical field of cylinder liner machining equipment, specifically to a turning device for machining bimetallic cylinder liners. Background Technology

[0002] In the machining and production of bimetallic cylinder liners, the turning process is a core step in ensuring the precision and performance of the cylinder liner's inner wall, and its machining efficiency directly affects product capacity and production costs. However, traditional turning equipment generally suffers from the technical bottleneck of not being able to simultaneously turn the inner walls of both bimetallic cylinder liners, resulting in low machining efficiency, making it difficult to meet the needs of large-scale production, and hindering the application and promotion of bimetallic cylinder liners in high-end machinery fields.

[0003] Existing turning equipment mostly adopts a single-station machining mode, meaning that only one cylinder liner's inner wall can be turned in a single setup. When processing bimetallic cylinder liners, both cylinder liners need to be clamped, positioned, and turned separately. This not only increases the number of setups and auxiliary time but also leads to a decrease in the machining accuracy of the inner wall due to the accumulation of positioning errors from multiple setups. For example, when machining bimetallic cylinder liners for diesel engines, traditional equipment requires two separate machining operations to complete the inner wall turning of both cylinder liners. The machining time for a single set is more than 50% longer than that of a dual-station equipment, and the coaxiality error of the inner wall can reach 0.03mm, which cannot meet the assembly requirements of high-precision engines.

[0004] Meanwhile, single-station turning leads to low equipment utilization, especially when dealing with large-diameter, long-stroke bimetallic cylinder liners, where the idle travel time of the machine tool spindle and tool post increases significantly. Furthermore, frequent clamping operations exacerbate fixture wear and increase equipment maintenance costs. With the explosive growth in demand for bimetallic cylinder liners from fields such as new energy vehicles and construction machinery, traditional turning devices, due to their drawbacks of "single-station processing, low efficiency, and unstable precision," can no longer meet the urgent needs of modern production for "high efficiency, high precision, and low cost." There is an urgent need to develop a new turning device capable of simultaneously turning the inner walls of two cylinder liners to solve the industry problems of "processing efficiency bottlenecks and insufficient production capacity." Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a turning device for machining bimetallic cylinder liners, which solves the technical problem that conventional turning devices in the prior art generally cannot simultaneously turn the inner walls of both cylinder liners when facing bimetallic cylinder liners, requiring secondary fixing and adjustment.

[0006] According to one aspect, at least one embodiment of this disclosure provides a turning apparatus for machining bimetallic cylinder liners, comprising:

[0007] The equipment frame and the uprights, wherein the uprights are fixed to the surface of the equipment frame;

[0008] The platform and the drive turning assembly are provided, wherein the platform is mounted on the equipment rack and the drive turning assembly is mounted on the equipment rack and the platform.

[0009] A clamping assembly is disposed on the column;

[0010] The drive turning assembly includes a transverse lead screw, which is disposed within the platform. A first guide rod is disposed within the platform. A fixed seat is fixed on the platform. A movable seat is slidably connected to the guide rod. A high-speed motor is mounted on both the movable seat and the fixed seat. A tool sleeve is disposed at the output end of the high-speed motor.

[0011] As a further technical solution, the movable seat is provided with a pair of side frames, each of which is equipped with a support cylinder. The output end of the support cylinder is provided with a stabilizing seat, which is supported on the platform surface.

[0012] As a further technical solution, the equipment frame is provided with a slide rail, the platform is slidably connected to the slide rail, and a longitudinal lead screw is installed inside the top of the equipment frame, the longitudinal lead screw being connected to the platform by a threaded connection.

[0013] As a further technical solution, the clamping assembly includes a vertical lead screw, which is disposed inside the column. A pair of vertical rails are disposed inside the column, and a pair of crossbars are slidably connected to the vertical rails.

[0014] As a further technical solution, the crossbars are all connected to the vertical lead screws by threaded engagement, and a first clamping frame is fixedly connected to each crossbar. A second clamping frame is slidably connected inside the crossbar, and a fixing bolt is threadedly connected to each of the second clamping frames.

[0015] As a further technical solution, the first clamping bracket corresponds to the position of the fixed base.

[0016] As a further technical solution, both the first clamping frame and the second clamping frame are arc-shaped transition structures.

[0017] As a further technical solution, the vertical lead screw has a double-segment thread structure, and the thread directions at both ends of the vertical lead screw are opposite.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, the drive turning assembly can flexibly adjust the distance between the fixed seat and the moving seat and the platform position through the linkage of the transverse lead screw and the longitudinal lead screw, so as to realize the synchronous turning of double cylinder liners of different specifications. This solves the problem of low efficiency in traditional single-station turning. After the support cylinder extends, the stable seat supports the platform, which enhances the stability of the turning process, reduces vibration and ensures machining accuracy. The high-speed motor drives the tool holder to rotate at high speed. With the dual-station design, the inner wall of the double cylinder liner can be turned at the same time in one clamping, which greatly improves the machining efficiency, reduces the number of clamping times and positioning errors, and improves production efficiency and product accuracy.

[0020] 2. In this disclosure, the clamping assembly utilizes the double-segment reverse thread structure of the vertical lead screw, which drives the two crossbeams to move synchronously during rotation, keeping the axis position from deviating. The vertical track provides guidance for the crossbeams, ensuring smooth movement. The arc-shaped transition structure of the first clamping frame and the second clamping frame fits against the outer wall of the cylinder liner. The position of the second clamping frame can be adjusted by fixing bolts to adapt to the clamping requirements of cylinder liners of different diameters, achieving stable clamping of the double cylinder liners, avoiding displacement or shaking during turning, providing reliable support for turning, and ensuring turning accuracy. At the same time, the synchronous clamping design of the double cylinder liners reduces clamping time and improves processing efficiency. Attached Figure Description

[0032] like Figures 1-3 As shown, a turning apparatus for machining bimetallic cylinder liners is illustrated in one embodiment of this disclosure, comprising:

[0033] The equipment frame 1 and the column 2 are fixed to the surface of the equipment frame 1;

[0034] Platform 3 and drive turning assembly 4, wherein platform 3 is mounted on the equipment frame 1 and drive turning assembly 4 is mounted on the equipment frame 1 and platform 3;

[0035] Clamping assembly 5, which is disposed on the column 2;

[0036] The drive turning assembly 4 includes a transverse lead screw 4-1, which is disposed within the platform 3. A first guide rod 4-2 is disposed within the platform 3. A fixed seat 4-3 is fixed on the platform 3. A movable seat 4-4 is slidably connected to the guide rod. A high-speed motor 4-5 is mounted on both the movable seat 4-4 and the fixed seat 4-3. A tool sleeve 4-6 is disposed at the output end of the high-speed motor 4-5. A pair of side frames 4-7 are disposed on the movable seat 4-4. A support cylinder 4-8 is mounted on each side frame 4-7. A stabilizing seat 4-9 is disposed at the output end of the support cylinder 4-8. The stabilizing seat 4-9 is supported on the surface of the platform 3. A slide rail 4-10 is disposed on the equipment frame 1. The platform 3 is slidably connected to the slide rail 4-10. A longitudinal lead screw 4-11 is installed inside the top of the equipment frame 1. The longitudinal lead screw 4-11 is connected to the platform 3 by a threaded connection.

[0037] In some examples, a drive turning assembly 4 is designed to achieve efficient turning of bimetallic cylinder liners. This assembly uses a transverse leadscrew 4-1 within the platform 3 as its core transmission component. A first guide rod 4-2 is arranged parallel to the transverse leadscrew 4-1, providing sliding guidance for the moving base 4-4. High-speed motors 4-5 on the moving base 4-4 and the fixed base 4-3 respectively drive the tool holder 4-6 to rotate, achieving the turning of the cylinder liner. A support cylinder 4-8 is mounted on the side frame 4-7 of the moving base 4-4, and its output end has a stabilizing seat 4-9 that can support it on the surface of the platform 3, enhancing stability during the turning process, reducing vibration, and improving machining accuracy.

[0038] The slide rail 4-10 on the equipment frame 1 engages with the longitudinal lead screw 4-11. The longitudinal lead screw 4-11 drives the platform 3 to move longitudinally along the slide rail 4-10 via a thread, achieving precise adjustment of the turning position. By controlling the rotation of the transverse lead screw 4-1 and the longitudinal lead screw 4-11, the distance between the two tool holders 4-6 can be flexibly adjusted to meet the machining requirements of different specifications of double cylinder liners. Simultaneously, the two cylinder liners are turned synchronously, significantly improving machining efficiency. With the help of the linkage control of the double lead screws, the stable support of the support cylinder 4-8, and the drive of the high-speed motor 4-5, the turning assembly 4 can precisely adjust the machining position and distance, achieving efficient and stable machining of bimetallic cylinder liners.

[0039] like Figures 1-3 As shown in the figure, the clamping assembly 5 in this embodiment includes a vertical lead screw 5-1, which is disposed inside the column 2. A pair of vertical rails are disposed inside the column 2, and a pair of crossbars 5-3 are slidably connected to the vertical rails. The crossbars 5-3 are all connected to the vertical lead screw 5-1 by threaded engagement. A first clamping frame 5-4 is fixedly connected to each crossbar 5-3, and a second clamping frame 5-5 is slidably fitted inside the crossbar 5-3. A fixing bolt 5-6 is threadedly connected to each of the second clamping frames 5-5.

[0040] In some examples, a clamping assembly 5 is designed to ensure the stability of the bimetallic cylinder liner during the turning process. This assembly uses a vertical lead screw 5-1 inside the column 2 as the transmission core. A pair of vertical rails are set parallel to the vertical lead screw 5-1 to provide vertical sliding guidance for the crossbeam 5-3. The crossbeam 5-3 is threadedly engaged with the vertical lead screw 5-1. When the vertical lead screw 5-1 rotates, it drives the crossbeam 5-3 to move up and down along the vertical rails, realizing adaptive adjustment for cylinder liners of different heights.

[0041] The clamping structure is formed between the first clamping bracket 5-4 fixed on the crossbeam 5-3 and the second clamping bracket 5-5 of the sliding sleeve. The position of the second clamping bracket 5-5 can be adjusted by rotating the fixing bolt 5-6, thereby achieving clamping of cylinder liners of different diameters. The independent adjustment design of the two crossbeams 5-3 allows for precise clamping of the two cylinder liners separately, ensuring that the cylinder liners do not shift or wobble during turning. Through the lifting and lowering adjustment of the vertical screw 5-1, the synergistic effect of the two clamping brackets, and the tightening of the fixing bolt 5-6, the clamping assembly 5 can stably and reliably clamp the bimetallic cylinder liners, providing a solid support foundation for turning.

[0042] For example, such as Figure 1 As shown, the first clamping bracket 5-4 corresponds to the fixed base 4-3.

[0043] In some examples, the first clamping bracket 5-4 maintains the same axial position as the fixed base 4-3 to ensure the axial position during turning.

[0044] For example, such as Figure 2 As shown, both the first clamping frame 5-4 and the second clamping frame 5-5 have an arc-shaped transition structure.

[0045] In some examples, the curved transition structure allows for a better fit to the outer wall of the cylinder liner, resulting in a more robust fit.

[0046] For example, such as Figure 1 As shown, the vertical lead screw 5-1 has a double-segment thread structure, and the thread directions at both ends of the vertical lead screw 5-1 are opposite.

[0047] In some examples, the opposite threaded structure allows the two cross arms 5-3 to move synchronously when the vertical lead screw 5-1 rotates, maintaining the axial position and preventing skewing.

[0048] In actual use: the equipment frame 1 is fixed, the column 2 is installed on the surface of the equipment frame 1, the platform 3 is connected to the equipment frame 1 through the slide rail 4-10, the longitudinal lead screw 4-11 passes through the platform 3 and is driven by a motor, the transverse lead screw 4-1 and the first guide rod 4-2 are installed inside the platform 3, the fixed seat 4-3 is fixed on the platform 3, the movable seat 4-4 is slidably connected to the platform 3 through the guide rod, the high-speed motor 4-5 is installed on the movable seat 4-4 and the fixed seat 4-3 and connected to the tool sleeve 4-6, the side frame 4-7 is fixed on the movable seat 4-4, the support cylinder 4-8 is installed on the side frame 4-7 and its output end is connected to the stabilizing seat 4-9, and the vertical lead screw 5-1 of the clamping assembly 5 is installed on the column 2. Inside, the vertical rails are set in parallel. The crossbar 5-3 is threadedly engaged with the vertical screw 5-1 and slides along the rail. The first clamping frame 5-4 is fixed on the crossbar 5-3. The second clamping frame 5-5 is slidably fitted inside the crossbar 5-3 and locked by the fixing bolt 5-6. In use, the longitudinal screw 4-11 adjusts the position of the platform 3, the transverse screw 4-1 adjusts the distance between the moving seat 4-4 and the fixed seat 4-3, the support cylinder 4-8 extends to make the stabilizing seat 4-9 support the platform 3, the vertical screw 5-1 of the clamping assembly 5 rotates to drive the crossbar 5-3 to move, the first clamping frame 5-4 and the second clamping frame 5-5 cooperate to clamp the double cylinder sleeve, and the high-speed motor 4-5 drives the tool sleeve 4-6 to rotate for turning.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
