Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically a symmetrical correction device for machining flywheel housings. Background Technology

[0002] The flywheel housing is a crucial component of a car engine, and its quality directly affects the engine's performance and lifespan. Flywheel housing machining is a complex and delicate process. After forming, the flywheel housing typically requires precision machining, including turning, milling, and drilling, to ensure that the flywheel housing's dimensions, shape, and surface roughness meet design requirements. During machining, the flywheel housing needs to be clamped and held in place on a machining table.

[0003] Currently, when workers drill holes in the flywheel housing, they use a clamp to hold the flywheel housing on the worktable. Before clamping, the position of the flywheel housing needs to be corrected, and then the clamp is used to hold the flywheel housing. The correction process usually involves workers using their experience or other auxiliary tools to position the flywheel housing, which is troublesome, time-consuming and labor-intensive. Summary of the Invention

A plug rod is fixedly connected to the junction of the rotating plate and the clamping plate, and the plug rod is inserted into a corresponding insertion hole. A fixed plate is fixedly connected to the upper end of the first slide rod, and a slip ring is fixedly connected to the lower end of the fixed plate by a first spring. Both the first spring and the slip ring are sleeved on the outer side of the upper end of the first slide rod, and the slip ring is slidably connected to the first slide rod.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-5As shown, the symmetrical correction device for flywheel housing processing according to the present invention includes a base plate 1. A positioning rod 2 is fixedly connected to the middle of the upper end of the base plate 1. Movable grooves 3 are opened in the middle of both sides of the upper end of the base plate 1. A first slider 4 is slidably connected inside the movable groove 3. A clamping plate 5 is fixedly connected to the upper end of the first slider 4. The two clamping plates 5 are slidably connected to the upper end of the base plate 1. The width of the two clamping plates 5 is wider than the width of the upper end of the corresponding movable groove 3. Two insertion holes 6 are symmetrically opened on the opposite side of the two clamping plates 5. A rotating mechanism 7 is installed at each insertion hole 6. The rotating mechanisms 7 installed on the two clamping plates 5 correspond one-to-one. Each of the two corresponding rotating mechanisms 7 is connected to a pressing mechanism 8. Each of the four corners of the upper end of the base plate 1 is fixedly connected to a stop block 9, with each block corresponding to the other. The pressing mechanism 8 includes a positioning sleeve 81, which is sleeved on the outer side of the upper end of the positioning rod 2. A rubber pad 82 is fixedly connected to the lower end of each positioning sleeve 81. Hollow plates 83 are fixedly connected to both sides of the positioning sleeve 81. A second slider 84 is slidably connected inside each hollow plate 83. A second sliding rod 85 is fixedly connected to each second slider 84. One end of each second sliding rod 85 passes through and slidably connects to the side wall of the corresponding hollow plate 83. A second spring 86 is fitted on the outer side of the first slide bar 84. The second spring 86 and the second slide bar 85 are located on the same center line. The two ends of the second spring 86 are fixedly connected to the side wall of the corresponding second slide bar 84 and the inner wall of the hollow plate 83, respectively. A pull plate 87 is fixedly connected to one end of the second slide bar 85. A pull groove 88 is opened on one side of the upper end of the pull plate 87. The pull groove 88 is arranged vertically. A limit plate 89 is rotatably connected to the other side of the upper end of the pull plate 87. A carrier plate 810 is fixedly connected to the outer wall of the hollow plate 83. A sliding plate 811 is inserted into the carrier plate 810. The rotating mechanism 7 includes a first slide bar 7. 1. A first slide rod 71 is installed through the corresponding pull plate 87. The first slide rod 71 is snapped onto the limiting plate 89. A rotating plate 72 is fixedly connected to the lower end of the first slide rod 71. The rotating plate 72 is tightly attached to the corresponding clamping plate 5. An insert rod 73 is fixedly connected at the junction of the rotating plate 72 and the clamping plate 5. The insert rod 73 is inserted into the corresponding insertion hole 6. A fixing plate 74 is fixedly connected to the upper end of the first slide rod 71. A slip ring 75 is fixedly connected to the lower end of the fixing plate 74 through a first spring 76. The first spring 76 and the slip ring 75 are both sleeved on the outer side of the upper end of the first slide rod 71. The slip ring 75 is slidably connected to the first slide rod 71.

[0025] Specifically, the two positioning sleeves 81 abut against each other and each abutting point is provided with an arc-shaped groove. The arc-shaped grooves on the two positioning sleeves 81 can form a circular structure and the diameter of the circular structure is the same as the diameter of the positioning rod 2. The positioning sleeves 81 can be tightly fitted onto the positioning rod 2, which makes it easy to align the flywheel housing and the base plate 1.

[0026] Specifically, the cross-sections of the moving groove 3 and the first slider 4 are both convex and their shapes match. The upper end of the first slider 4 is flush with the upper end of the base plate 1, which can fix the first slider 4 on the base plate 1 without affecting the sliding of the first slider 4.

[0027] Specifically, the lower end of the rotating plate 72 has a semi-circular structure and is located on the same center line as the insertion rod 73. The lower end of the rotating plate 72 abuts against the upper end of the base plate 1, so that the hollow plate 83 and the pull plate 87 can be abutted against the upper end of the base plate 1 when clamped.

[0028] In use, place the flywheel housing on the upper end of the base plate 1 and fit it around the outside of the positioning rod 2. Secure the clamping plate 5 to the corresponding protruding part on the outside of the flywheel housing. The shape of the clamping plate 5 should match the protruding part on the outside of the flywheel housing to ensure that the clamping plate 5 is firmly secured to the flywheel housing. Then pull the pull plate 87 away from the hollow plate 83. During this process, the second spring 86 will be continuously compressed until the distance between the two insert rods 73 is greater than the distance between the two clamping plates 5. Align the insert rods 73 with the insertion holes 6 on the clamping plates 5, release the pull plate 87, and the second spring 86 will push the second sliding rod 85. The second sliding rod 85 will then pull the pull plate 87 closer to the hollow plate 83 until the pull plate 87 abuts against the clamping plate 5. Insert the insert rods 73 into the insertion holes 6. At this time, the positioning sleeve 81 is fitted onto the positioning rod 2. Repeat this process to install another compression mechanism 8, tightening the two clamping plates 5. Clamped tightly to the outside of the flywheel housing, the flywheel housing and the middle of the base plate 1 are aligned to achieve the purpose of correction. Rotate the limiting plate 89 until it is rotated out from the side wall of the first slide rod 71. Pull the positioning sleeve 81 upward to press the pull plate 87 against the slip ring 75 and continuously squeeze the first spring 76. At the same time, the rotating plate 72 can be rotated until the first slide rod 71 and the base plate 1 are parallel. At this time, the pull plate 87 presses against the stop block 9, and the first spring 76 pushes the pull plate 87 to press the positioning sleeve 81 against the outside of the flywheel housing. The rubber pad 82 on the positioning sleeve 81 can prevent scratching the flywheel housing and increase the friction between the positioning sleeve 81 and the flywheel housing. Then slide the slide plate 811 to press the slide plate 811 against the upper end of the flywheel housing, clamping and fixing the flywheel housing to the upper end of the base plate 1. Then start the drilling equipment to drill holes in the flywheel housing.
