Description

Technical Field

[0001] This utility model relates to the field of cylinder processing technology, specifically a fixed fixture for machining cylinders on a split lathe. Background Technology

[0002] In the field of cylinder machining for split-type lathes, the cylinder is a key component of the lathe's transmission system, and its machining accuracy directly affects the overall operational stability and transmission efficiency of the lathe. Therefore, it places high demands on the clamping stability, ease of operation, and adaptability of the fixed fixtures during the machining process.

[0003] According to announcement number CN 218312045 U, a fixing fixture for machining a constant pressure cylinder includes a mounting plate with a fixing groove. One end of the fixing groove is rotatably connected to the mounting plate, and a scale for measuring the rotation angle of the fixing groove is concentrically provided at one end of the rotatable connection of the fixing groove. The scale is fixed on the mounting plate. An ear plate is provided at the end of the mounting plate away from the rotatable connection of the fixing groove. An adjusting screw is transversely provided through the ear plate and threadedly connected to the ear plate. A wedge is rotatably mounted at one end of the adjusting screw, and the upper surface of the wedge is inclined and fits against the bottom surface of the fixing groove.

[0004] This device fixes the cylinder in a groove, and by rotating the adjusting screw, it drives the wedge to rotate the groove, causing the cylinder to be at different angles. The angle of rotation is observed by watching the dial, which facilitates milling on the inclined surface of the cylinder. However, this device only clamps the cylinder and cannot rotate it, therefore it cannot machine different parts of the cylinder. Utility Model Content

[0005] The purpose of this utility model is to provide a fixed fixture for machining cylinders on a split lathe, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixed fixture for machining cylinders on a split lathe, comprising a base, fixed columns symmetrically fixedly connected to the top of the base in the front, back, left and right directions, fixed seats fixedly connected to the top of the four fixed columns, a clamping and rotating mechanism provided on the surface of the fixed seats, and a pick-and-place mechanism provided on the top of the base. The clamping and rotating mechanism includes a first fixed plate, which is fixedly connected to the left side of the fixed base. A first hydraulic cylinder is fixedly connected to the left side of the first fixed plate. A movable plate is fixedly connected to the output end of the first hydraulic cylinder. A servo motor is fixedly connected to the left side of the movable plate near the top. A first clamping member is fixedly connected to the output end of the servo motor. A second fixed plate is fixedly connected to the top left side of the fixed base. Guide rods are symmetrically fixedly connected to the left side of the second fixed plate near the top. A third fixed plate is fixedly connected to the top right side of the fixed base. A rotating shaft is rotatably connected to the left side of the third fixed plate near the top. A second clamping member is fixedly connected to the other end of the rotating shaft.

[0007] Preferably, the first clamp and the second clamp are on the same horizontal line.

[0008] Preferably, the left ends of the two guide rods are fixedly connected to the right side of the first fixing plate.

[0009] Preferably, the right side of the movable plate near the bottom has a hole that matches the guide rod, and the movable plate is slidably connected to the surface of the guide rod through the hole, so that the left and right movement of the movable plate is more stable.

[0010] Preferably, the picking and placing mechanism includes a second hydraulic cylinder, which is fixedly connected to the top of the base. A lifting plate is fixedly connected to the output end of the second hydraulic cylinder. Slide rods are symmetrically fixedly connected to the top of the lifting plate in all directions. Placement plates are fixedly connected to the top of the four slide rods in all directions. Limiting blocks are symmetrically fixedly connected to the top of the placement plates in all directions.

[0011] Preferably, the top of the fixed base has a hole that matches the slide rod, and the slide rod surface passes through and slides up and down in the hole.

[0012] Preferably, the four limiting blocks limit the split lathe cylinder, preventing it from moving back and forth on the placement plate.

[0013] Compared with the prior art, this utility model provides a split-type lathe cylinder machining fixture, which has the following advantages: 1. This fixed fixture for machining split-type lathe cylinders includes a clamping and rotating mechanism in which a first hydraulic cylinder drives a moving plate to slide smoothly along a guide rod. This, combined with a servo motor-driven first clamping member and a fixed second clamping member, enables precise clamping of split-type lathe cylinders of different specifications. Furthermore, the first and second clamping members are on the same horizontal line, ensuring the stability of the cylinder axis during clamping and preventing errors caused by clamping offset during machining, thus improving machining accuracy. The servo motor can drive the clamped cylinder to rotate, adapting to the multi-process machining requirements of lathes, reducing manual intervention steps, and improving machining efficiency.

[0014] 2. The fixed fixture for machining cylinders on this split lathe has a pick-and-place mechanism that uses a second hydraulic cylinder to drive a slide rod to raise and lower the placement plate. The holes on the fixed seat guide the slide rod, ensuring that the placement plate rises and falls smoothly. The four limit blocks on the placement plate can limit the cylinders in the front and back, preventing the cylinders from slipping during the pick-and-place process. This simplifies the cylinder loading and unloading operation and reduces the safety hazards during manual handling. Attached Figure Description

[0019] This utility model provides the following technical solution: Example 1 Please see Figure 1-3 This utility model provides a technical solution: a fixed fixture for machining cylinders on a split lathe, including a base 1, fixed columns 2 are symmetrically fixedly connected to the top of the base 1 in the front, back and left and right, fixed seats 3 are fixedly connected to the top of the four fixed columns 2, a clamping and rotating mechanism 4 is provided on the surface of the fixed seat 3, and a picking and placing mechanism 5 is provided on the top of the base 1. The clamping and rotating mechanism 4 includes a first fixed plate 41, which is fixedly connected to the left side of the fixed base 3. A first hydraulic cylinder 42 is fixedly connected to the left side of the first fixed plate 41. A moving plate 43 is fixedly connected to the output end of the first hydraulic cylinder 42. A servo motor 44 is fixedly connected to the left side of the moving plate 43 near the top. A first clamp 45 is fixedly connected to the output end of the servo motor 44. A second fixed plate 46 is fixedly connected to the top left side of the fixed base 3. Guide rods 47 are symmetrically fixedly connected to the left side of the second fixed plate 46 near the top. A third fixed plate 48 is fixedly connected to the top right side of the fixed base 3. A rotating shaft 49 is rotatably connected to the left side of the third fixed plate 48 near the top. A second clamp 411 is fixedly connected to the other end of the rotating shaft 49.

[0020] The first clamp 45 and the second clamp 411 are on the same horizontal line.

[0021] The left ends of the two guide rods 47 are fixedly connected to the right side of the first fixed plate 41.

[0022] The right side of the movable plate 43 near the bottom has a hole that matches the guide rod 47, and the movable plate 43 is slidably connected to the surface of the guide rod 47 through the hole, making the left and right movement of the movable plate 43 more stable.

[0023] Example 2 Please see Figure 4-5 Furthermore, based on Embodiment 1, the pick-and-place mechanism 5 is obtained.

[0024] The pick-and-place mechanism 5 includes a second hydraulic cylinder 51, which is fixedly connected to the top of the base 1. A lifting plate 52 is fixedly connected to the output end of the second hydraulic cylinder 51. Slide rods 53 are fixedly connected symmetrically to the top of the lifting plate 52. Placement plates 54 are fixedly connected to the top of the four slide rods 53. Limiting blocks 55 are fixedly connected symmetrically to the top of the placement plate 54.

[0025] The top of the fixed base 3 has a hole that matches the slide rod 53, and the slide rod 53 is connected to the hole by sliding up and down through the surface of the slide rod 53.

[0026] Four limit blocks 55 limit the cylinder of the split lathe, so that the cylinder of the split lathe will not move back and forth on the placement plate 54.

[0027] In actual operation, when this device is used, in the pick-and-place mechanism 5, the second hydraulic cylinder 51 is in a retracted state, driving the lifting plate 52, slide rod 53, and placement plate 54 to the lowest position. The four limiting blocks 55 on the top of the placement plate 54 are in a ready-to-bearing state. The split lathe cylinder to be processed is placed on the placement plate 54. The four limiting blocks 55 limit the cylinder in front and behind to prevent the cylinder from shifting on the placement plate 54. The second hydraulic cylinder 51 is activated, and its output end extends to push the lifting plate 52 upward, driving the slide rod 53 to slide upward along the matching hole opened on the top of the fixed seat 3 until the cylinder on the placement plate 54 rises to the clamping height that matches the first clamp 45 and the second clamp 411 of the clamping and rotating mechanism 4. Then the second hydraulic cylinder 51 stops operating. Initially, the first hydraulic cylinder 42 is in a retracted state, driving the moving plate 43 to move to the left along the guide rod 47, so that there is a sufficient distance between the first clamp 45 and the second clamp 411 to accommodate the cylinder. The first hydraulic cylinder 42 is activated, and its output end extends to push the moving plate 43 to slide smoothly to the right along the guide rod 47 until the first clamp 45 and the second clamp 411 clamp the two ends of the cylinder together. Then, the first hydraulic cylinder 42 maintains pressure to ensure stable clamping. According to the lathe processing requirements, the servo motor 44 is activated, and its output end drives the first clamp 45 to rotate, thereby driving the clamped cylinder to rotate synchronously, realizing multi-directional processing of the cylinder. During the processing, the support frame formed by the base 1 and the fixed column 2 ensures the stability of the overall structure and avoids shaking that affects the processing accuracy. After the cylinder is processed, the servo motor 44 stops operating, the output end of the first hydraulic cylinder 42 retracts, and drives the moving plate 43 and the first clamp 45 to move to the left to release the cylinder. The second hydraulic cylinder 51 is activated, and its output end retracts to drive the lifting plate 52, the slide rod 53 and the placement plate 54 to move downward until the placement plate 54 is lowered to the initial low position. The operator can then remove the processed cylinder to complete one processing cycle.
