Description

Technical Field

[0001] This utility model relates to the field of crankshaft blank technology, specifically a crankshaft blank position flipping device. Background Technology

[0002] The crankshaft is the most important component in an engine. Whether it is a two-cylinder, three-cylinder, or four-cylinder engine, the crankshaft is required as the main connecting and transmission component. It bears the force transmitted from the connecting rod and converts it into torque, which is output through the crankshaft to drive other accessories on the engine.

[0003] There are currently no effective solutions to the problems in the relevant technologies.

[0004] 1. The existing crankshaft blank position flipping device requires the crankshaft blank that has been fixed to be loosened before it can be flipped. This is cumbersome and causes many inconveniences for the workers, reducing work efficiency. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a crankshaft blank position flipping device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A crankshaft blank position flipping device includes a worktable, a fixing component, a support block, a support shaft, and a push-pull component. A first support plate and a second support plate are fixedly connected to both ends of the upper surface of the worktable. The fixing component is disposed inside the support block. The support block includes a first connecting shaft, a first connecting plate, and a first limiting block. A limiting sleeve is fixedly connected to the outer wall of the support shaft. A limiting groove is formed inside the limiting sleeve. The push-pull component includes a second connecting plate, a second connecting shaft, a third connecting plate, and a second limiting block. The first limiting block, the limiting sleeve, and the second limiting block are movably connected together.

[0008] A further improvement of the present invention is that: the first connecting shaft is fixedly connected to one end of the support block, one end of the first connecting plate is fixedly connected to the end of the first connecting shaft away from the support block, and the first connecting shaft is movably connected to the inside of the first support plate through a bearing.

[0009] Using the above technical solution, the first connecting shaft can rotate freely inside the first support plate under the action of the bearing.

[0010] A further improvement of the present invention is that: the first limiting block is fixedly connected to the end of the first connecting plate away from the first connecting shaft, the first limiting block and the limiting groove are adapted to each other, and the first limiting block is slidably connected to the inside of the limiting groove.

[0011] Using the above technical solution, the first limiting block can slide inside the limiting groove. If the first connecting plate drives the first limiting block to rotate around the first connecting shaft, the first limiting block will slide inside the limiting groove and drive the limiting sleeve to swing around the support shaft.

[0012] A further improvement of this utility model is that the support shaft is movably connected to the interior of the first support plate and the second support plate via bearings, and the first support plate and the second support plate are connected together via the support shaft.

[0013] Using the above technical solution, the support shaft in this solution can rotate freely inside the first support plate and the second support plate under the action of the bearing.

[0014] A further improvement of the present invention is that: the second connecting shaft is movably connected to the inside of the second support plate via a bearing; the second connecting shaft is fixedly connected to one end of the second connecting plate; the end of the second connecting shaft away from the second connecting plate is fixedly connected to one end of the third connecting plate; the second limiting block is fixedly connected to the end of the third connecting plate away from the second connecting shaft; and the second limiting block is slidably connected to the inside of the limiting groove.

[0015] Using the above technical solution, the second connecting shaft can rotate freely inside the second support plate under the action of the bearing, which can push the second connecting plate away from the end of the second connecting shaft, so that the second connecting plate can drive the second connecting shaft to rotate, and drive the third connecting plate to drive the second limiting block to rotate around the second connecting shaft. At this time, the second limiting block will sit inside the limiting groove and slide, and will drive the limiting sleeve to swing around the support shaft.

[0016] A further improvement of the present invention is that the fixing component includes a dual-axis motor, which is fixedly connected to the inside of the support block. Both ends of the dual-axis motor are fixedly connected to threaded rods via couplings, and the outer wall of the threaded rods is provided with connecting blocks.

[0017] Using the above technical solution, the dual-axis motor in the solution can drive the threaded rods at both ends to rotate.

[0018] A further improvement of this utility model is that: the connecting block has a threaded groove inside, the connecting block and the threaded rod are threaded together through the threaded groove, and a sleeve is fixedly connected to one end of the connecting block.

[0019] Using the above technical solution, when the threaded rod rotates, it can drive the connecting blocks to move closer to each other under the action of the threaded groove and the threaded rod meshing together, thereby driving the clamp to clamp and fix the crankshaft blank that needs to be fixed, providing good stability.

[0020] A further improvement of this utility model is that: an extension plate is fixedly connected to the upper and lower ends of both sides of the support block, a sliding groove is provided inside the extension plate, and a slider is fixedly connected to the upper and lower ends of the connecting block, and the slider is slidably connected inside the sliding groove.

[0021] Using the above technical solution, the slider and groove in the solution can limit the connecting block, thereby enabling the connecting block to make linear sliding motion.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. By pushing and pulling the second connecting plate, the second limiting block is driven to rotate around the second connecting shaft, causing the second limiting block to slide in the limiting groove. At this time, the limiting sleeve will swing around the support shaft, and the first limiting block will slide in the limiting groove. This will cause the first connecting plate to rotate around the first connecting shaft, which in turn will cause the support block to rotate the crankshaft blank clamped and fixed by the fixing component. This makes it convenient for workers to operate, provides convenience, and improves work efficiency.

[0024] 2. The dual-axis motor drives the threaded rods at both ends to rotate. When the threaded rods rotate, they can drive the connecting blocks to move closer to each other under the action of the threaded groove and the threaded rod threads engaging together. This causes the clamping sleeve to clamp and fix the crankshaft blank that needs to be fixed, providing good stability. Attached Figure Description

[0033] According to an embodiment of the present invention, a crankshaft blank position flipping device is provided.

[0034] Example 1;

[0035] like Figure 1-4 As shown, the crankshaft blank position flipping device according to an embodiment of the present utility model includes a worktable 1, a fixing component 2, a support block 3, a support shaft 6, and a push-pull component 7. The two ends of the upper surface of the worktable 1 are fixedly connected to a first support plate 4 and a second support plate 5. The fixing component 2 is disposed inside the support block 3. The support block 3 includes a first connecting shaft 303, a first connecting plate 304, and a first limiting block 305.

[0036] In this embodiment, by pushing and pulling the second connecting plate 701, the third connecting plate 703 can drive the second limiting block 704 to rotate around the second connecting shaft 702, thereby causing the second limiting block 704 to slide inside the limiting groove 602. At this time, the limiting sleeve 601 will swing around the support shaft 6, and the first limiting block 305 will slide inside the limiting groove 602, thereby causing the first connecting plate 304 to rotate around the first connecting shaft 303. This will then cause the support block 3 to rotate the crankshaft blank clamped and fixed by the fixing component 2, making it easier for workers to operate, providing convenience, and improving work efficiency.

[0037] Example 2;

[0038] like Figure 1-4 As shown, in the crankshaft blank position flipping device according to an embodiment of the present invention, a first connecting shaft 303 is fixedly connected to one end of a support block 3, one end of a first connecting plate 304 is fixedly connected to the end of the first connecting shaft 303 away from the support block 3, the first connecting shaft 303 is movably connected to the inside of a first support plate 4 via a bearing, a first limiting block 305 is fixedly connected to the end of the first connecting plate 304 away from the first connecting shaft 303, the first limiting block 305 is adapted to a limiting groove 602, the first limiting block 305 is slidably connected to the inside of the limiting groove 602, and a support shaft 6 is movably connected to the inside of a first support plate 4 and a second support plate 5 via a bearing, and the first support plate 4 and the second support plate 5 are connected together via the support shaft 6.

[0039] In this embodiment, the first connecting shaft 303 can rotate freely inside the first support plate 4 under the action of the bearing, and the first limiting block 305 can slide inside the limiting groove 602. If the first connecting plate 304 drives the first limiting block 305 to rotate around the first connecting shaft 303, the first limiting block 305 will slide inside the limiting groove 602 and drive the limiting sleeve 601 to swing around the support shaft 6. The support shaft 6 can rotate freely inside the first support plate 4 and the second support plate 5 under the action of the bearing.

[0040] Example 3;

[0041] like Figure 1-4As shown, in the crankshaft blank position flipping device according to an embodiment of the present invention, the second connecting shaft 702 is movably connected to the inside of the second support plate 5 via a bearing, the second connecting shaft 702 is fixedly connected to one end of the second connecting plate 701, the end of the second connecting shaft 702 away from the second connecting plate 701 is fixedly connected to one end of the third connecting plate 703, the second limiting block 704 is fixedly connected to the end of the third connecting plate 703 away from the second connecting shaft 702, and the second limiting block 704 is slidably connected to the inside of the limiting groove 602.

The dual-axis motor 201 is fixedly connected to the inside of the support block 3. The two ends of the dual-axis motor 201 are fixedly connected to the threaded rod 202 through the coupling. The outer wall of the threaded rod 202 is provided with the connecting block 203. The connecting block 203 has a threaded groove inside. The connecting block 203 and the threaded rod 202 are threaded together through the threaded groove. One end of the connecting block 203 is fixedly connected to the sleeve 205. The upper and lower ends of both sides of the support block 3 are fixedly connected to the extension plate 301. The extension plate 301 has a sliding groove 302 inside. The upper and lower ends of the connecting block 203 are fixedly connected to the slider 204. The slider 204 is slidably connected inside the sliding groove 302.

[0042] In this embodiment, the second connecting shaft 702 can rotate freely inside the second support plate 5 under the action of the bearing, which can push the second connecting plate 701 away from one end of the second connecting shaft 702, so that the second connecting plate 701 can drive the second connecting shaft 702 to rotate, and drive the third connecting plate 703 to drive the second limiting block 704 to rotate around the second connecting shaft 702.

[0043] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0044] In practical applications,

[0045] In summary, by means of the above-mentioned technical solution of this utility model, the dual-axis motor 201 drives the threaded rods 202 at both ends to rotate. When the threaded rods 202 rotate, they can drive the connecting blocks 203 to move closer together under the action of the threaded grooves and the threaded rods 202 engaging with each other. This causes the clamping sleeve 205 to clamp and fix the crankshaft blank that needs to be fixed. When it is necessary to flip it, pushing or pulling the end of the second connecting plate 701 away from the second connecting shaft 702 will drive the third connecting plate 703 to drive the second limiting block 704 to the second connecting shaft 702. The first connecting plate 304 rotates around the support shaft 603, causing the second limiting block 704 to slide inside the limiting groove 602. This causes the limiting sleeve 601 to swing around the support shaft 6. As the limiting sleeve 601 swings, it causes the first limiting block 305 to slide inside the limiting groove 602. This causes the first connecting plate 304 to rotate around the first connecting shaft 303, driven by the first limiting block 305 and the limiting sleeve 601. This, in turn, causes the support block 3 to rotate and the fixed component 2 to flip the crankshaft blank, thus completing the flipping operation.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
