Description

Technical Field

[0001] This utility model relates to the field of jig technology, and in particular to a multi-directional machining jig for cylinder liners. Background Technology

[0002] The surface roughness of the cylinder liner's inner circle plays a crucial role in engine energy conservation and emission reduction. Currently, the industry commonly uses a plateau textured honing process with parameters Rpk < 0.3 and Rk ranging from 0.2 to 0.8. This honing technology is insufficient in initial break-in and fuel consumption, failing to meet increasingly stringent emission requirements. Therefore, an inner circle suspension honing technology is being used as a replacement. Suspension honing requires specialized production fixtures. According to announcement number CN204308738U, a specialized fixture for cylinder liner inner circle suspension honing is disclosed, comprising a cylindrical housing with a cover plate at the front end and a guide shaft connected to the rear end; a push rod first disposed within the housing, comprising two conical rings coaxially connected end-to-end, and a guide shaft second fitted with a gap within the guide shaft first. One end of the guide shaft second is connected to a propulsion cylinder first, and the other end is fixedly connected to the conical rings. The push rod 2, located within the housing, comprises two conical shafts coaxially connected end-to-end and a guide rod fitted within the guide shaft 2 with a gap. One end of the guide rod is connected to the propulsion cylinder 2, and the other end is fixedly connected to the conical shafts. At least two pairs of slots are evenly distributed on the cylindrical surface of the housing. A base material seat 1 and a base material seat 2 are provided in adjacent slots. The inner surfaces of the base material seat 1 and the base material seat 2 are slidably connected to the conical surfaces of the conical ring and the conical shaft respectively via wedges. The outer surfaces of the base material seat 1 and the base material seat 2 are respectively provided with an oil-retaining mesh base material and a mirror base material. However, the above technology still has some defects. For example, the traditional cylinder liner processing method usually uses a fixed fixture for positioning. This method is prone to problems such as workpiece displacement and deformation during processing, resulting in unstable processing accuracy, which needs to be improved. Utility Model Content

The device includes a throttle 20, a rotating shaft 21 mounted on the left side of the threaded rod 19, a clamping plate 22 mounted on the left side of the rotating shaft 21, a sliding rod 23 mounted on the right side of the clamping plate 22, a protective pad 24 mounted on the left side of the clamping plate 22, and an anti-slip pad 25 mounted on the left side of the protective pad 24. By incorporating a fixed groove 3, a rotating plate 4, a rotating plate 5, a protruding plate 6, a fixed block 7, a sliding groove 8, a sliding rod 9, a lifting block 10, a stop block 11, a locking block 12, and a spring 13, the device achieves multi-angle fixation and positioning of the workpiece, improving processing accuracy and efficiency. The design of components such as the sliding rod 9, the stop block 11, and the locking block 12 ensures that the workpiece remains stable during processing, reducing errors caused by vibration and other factors. The spring 13 can alleviate impact forces to a certain extent, protecting the workpiece and equipment. The overall structure is compact and easy to operate, suitable for machining cylinder liners of various specifications. Support columns 2 are evenly distributed at the four corners of the bottom of the base 1.

The sliding rod 9 is slidably connected to the fixed block 7 via the sliding groove 8, and the stop block 11 is slidably connected to the fixed block 7. The locking block 12 is slidably connected to the base 1 via the fixed groove 3, facilitating the sliding of the sliding rod 9 and locking block 12 and preventing them from being jammed by the fixed block 7 or the base 1 during use. When this occurs, the end of spring 13 away from stop 11 is fixed to the inner wall of fixed block 7. Spring 13 is slidably connected to slide rod 9 and fixed block 7, making it easier for spring 13 to slide and preventing spring 13 from being stuck by slide rod 9 during use.

Sliding rod 23 is slidably connected to support plate 15 through sliding groove 16, making it easier for threaded rod 19 to rotate and preventing threaded rod 19 from being stuck by protrusion 17 during use.

[0026] Example 2

[0027] Please see Figure 1-2 6. An electric telescopic rod 26 is installed at the top of the rotating plate 5. A placement platform 27 is set at the top of the electric telescopic rod 26. A limit rod 28 is installed at the bottom of the placement platform 27. A fixing rod 29 is installed at the top of the rotating plate 5. A limit groove 30 is opened at the top of the fixing rod 29. This realizes the automatic positioning and fixing of the workpiece, which improves the processing efficiency and accuracy. The design of the limit rod 28 and the limit groove 30 makes the workpiece stable during the processing, avoiding errors caused by vibration and other reasons. The use of the electric telescopic rod 26 simplifies the operation process, reduces labor intensity, and improves production efficiency. The overall structure is compact and easy to operate, suitable for machining cylinder liners of various specifications. The limiting rods 28 are symmetrically distributed on the left and right ends of the bottom of the placement platform 27. The limiting rods 28 are slidably connected to the fixed rods 29 through the limiting grooves 30. The fixed rods 29 are symmetrically distributed on the left and right ends of the top of the rotating plate 5, realizing the stable positioning and fixation of the workpiece. The limiting rods 28 are slidably connected to the limiting grooves 30 on the fixed rods 29, so that the workpiece can move along a fixed trajectory during the machining process, thereby ensuring machining accuracy and consistency.

[0028] Working Principle: First, place the base 1 in the desired position, ensuring the support column 2 firmly supports it. Then, place the cylinder liner to be processed on top of the placement platform 27. Next, activate the electric telescopic rod 26, causing it to slide the placement platform 27 upwards or downwards. Simultaneously, the limiting rod 28 slides through the limiting groove 30 within the fixed rod 29. Once the placement platform 27 has slid the cylinder liner to the desired position, squeeze the handle 20 to rotate. This causes the threaded rod 19 to rotate through the threaded groove 18 within the protrusion 17 and via the rotating shaft 21 on the right side of the clamping plate 22, thus rotating the clamping plate 22 towards the placement platform 27. Simultaneously, the sliding rod 23 at the bottom of the clamping plate 22 slides through the sliding groove 16 within the support plate 15. When the protective pad 24 and anti-slip pad 25 on the side of the clamping plate 22 contact the cylinder liner… Then it can be fixed firmly and processed. When the position needs to be adjusted during processing, pinch the lifting block 10 and pull it upward, so that the sliding rod 9 slides upward through the sliding groove 8 inside the fixed block 7. The sliding rod 9 drives the locking block 12 to slide upward together through the stop block 11. At this time, the locking block 12 slides out of the base 1 through the fixed groove 3 and slides completely into the fixed block 7. Then pinch the fixed block 7 and rotate it, so that the fixed block 7 drives the rotating plate 5 to rotate through the convex plate 6. At this time, the rotating plate 5 rotates at the top of the base 1 through the rotating plate 4. The rotating plate 5 drives the support plate 15 and the cylinder liner to rotate together through the side plate 14. When the cylinder liner is adjusted to the required position, the lifting block 10 can be released. At this time, under the elastic force of the spring 13 itself, the locking block 12 can slide downward through the stop block 11, so that the locking block 12 slides completely into the base 1 through the fixed groove 3, so as to achieve the effect of fixing the rotating plate 5.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
