Description

Technical Field

[0001] This utility model relates to a connecting rod type cylinder liner clamping device. Background Technology

[0002] An engine is a machine that converts other forms of energy into mechanical energy, such as internal combustion engines, external combustion engines, jet engines, and electric motors. Internal combustion engines typically convert chemical energy into mechanical energy. The term "engine" can refer to both the power-generating device and the entire machine including the power unit, such as a gasoline engine in a car. A car engine mainly consists of parts such as the cylinder block, cylinder liners, cylinder head, and cylinder head gasket. In the high-pressure casting process of the car engine block, the cylinder liners need to be placed into the die-casting mold, and molten aluminum is transported from the holding furnace to the die-casting machine for casting. Therefore, cylinder liner loading equipment is essential. However, in traditional engine block die-casting, the process of placing the cylinder liners is mostly done manually, resulting in low production efficiency for die-casting machines.

[0019] Example

[0020] Reference Figure 1 and Figure 2 This embodiment provides a connecting rod type cylinder liner clamping device, which includes a cylinder body 1, a cylinder rod 2, a tensioning assembly 3, and a cylinder liner clamping plate 4. The tensioning assembly 3 is disposed on the cylinder body 1 and the cylinder rod 2, and the cylinder liner clamping plate 4 is disposed on the tensioning assembly 3 for quickly clamping the cylinder liner.

[0021] The cylinder serves as the mounting base for this device, primarily consisting of a cylinder body 1 and a cylinder rod 2. The cylinder rod 2 is located at the head of the cylinder body 1. When using this device, the cylinder body 1 can be fixed to any robotic arm using fixing bolts. The robotic arm can drive the cylinder to move quickly to the position of the cylinder liner for rapid clamping. A tensioning assembly 3 is installed on the cylinder body 1 and the cylinder rod 2, and a cylinder liner clamping plate 4 is installed on the tensioning assembly 3. In this embodiment, the cylinder rod 2 drives the tensioning assembly 3 to expand outward and contract towards the center of the cylinder liner clamping plate 4, thereby achieving rapid clamping of the cylinder liner and improving the efficiency of die casting engine cylinder blocks in the die casting machine.

[0022] Specifically, the tensioning assembly 3 includes a first hinge seat 31, a second hinge seat 32, a third hinge seat 33, and three sets of connecting rods 34. The first hinge seat 31 is fixedly connected to the cylinder body 1 at the tail of the cylinder rod 2, the second hinge seat 32 is fixedly connected to the head of the cylinder rod 2, and the third hinge seat 33 is fixedly connected to the cylinder rod 2 between the first hinge seat 31 and the second hinge seat 32. The three sets of connecting rods 34 are evenly arranged at 120° on the first hinge seat 31, the second hinge seat 32, and the third hinge seat 33. The cylinder liner clamp 4 is disposed on the connecting rods 34.

[0023] In this embodiment, the tensioning assembly 3 mainly consists of a first hinge seat 31, a second hinge seat 32, a third hinge seat 33, and three sets of connecting rods 34. The first hinge seat 31 is fixedly mounted on the cylinder body 1 at the tail of the cylinder rod 2 by a first fixing bolt 9. The second hinge seat 32 is fixedly mounted on the head of the cylinder rod 2. The third hinge seat 33 is fixedly mounted on the cylinder rod 2 between the first hinge seat 31 and the second hinge seat 32. The three sets of connecting rods 34 are evenly arranged at 120° on the cylinder body 1. A hinge seat is provided on a first hinge seat 31, a second hinge seat 32, and a third hinge seat 33, and a hinge seat is also provided at the corresponding connection position of the first hinge seat 31, the second hinge seat 32, and the third hinge seat 33, so that the first hinge seat 31, the second hinge seat 32, and the third hinge seat 33 are rotatably connected to the three sets of connecting rods 34 by hinges. The cylinder liner clamping plate 4 is fixedly installed on the connecting rods 34, and the cylinder liner clamping plate 4 can be driven to move together through the connecting rods 34 in order to clamp the cylinder liner.

[0024] Specifically, the connecting rod 34 includes three first hinge plates 341, hinge pins 342, and a second hinge plate 343. The three first hinge plates 341 are rotatably connected to the first hinge seat 31, the second hinge seat 32, and the third hinge seat 33 respectively via hinge pins 342. The three first hinge plates 341 are on the same plane. The second hinge plate 343 is rotatably connected to the three first hinge plates 341 via hinge pins 342. The cylinder liner clamp 4 is fixedly connected to the second hinge plate 343.

[0025] In this embodiment, the connecting rod 34 mainly consists of three first hinge plates 341, hinge pins 342, and second hinge plates 343. One end of each of the three first hinge plates 341 is rotatably mounted on the first hinge seat 31, the second hinge seat 32, and the third hinge seat 33 respectively via hinge pins 342. After installation, all three first hinge plates 341 are on the same plane. The second hinge plate 343 is rotatably mounted on the other end of each of the three first hinge plates 341 via hinge pins 342, so that a telescopic connection structure is formed between the three first hinge plates 341, the second hinge plate 343, and the cylinder rod 2. The cylinder liner clamp 4 is fixedly mounted on the upper surface of the second hinge plate 343 by the second fixing bolt 10. By controlling the cylinder, the cylinder rod 2 is driven to move outward from the cylinder body 1. The cylinder rod 2 drives the second hinge seat 32 and the third hinge seat 33 to move away from the cylinder body 1. The second hinge seat 32 and the third hinge seat 33 drive one end of the first hinge plate 341 to move away from the cylinder body 1, so that the other end of the first hinge plate 341 drives the second hinge plate 343 to contract towards the center. The radial dimension of the tensioning assembly 3 continuously decreases, so that the entire tensioning assembly 3 can be inserted into the cylinder liner. Then, the cylinder is controlled to drive the cylinder rod 2 to move into the cylinder body 1. The cylinder rod 2 drives the second hinge seat 32 and the third hinge seat 33 to move towards the cylinder body 1. The second hinge seat 32 and the third hinge seat 33 drive one end of the first hinge plate 341 to move towards the cylinder body 1, so that the other end of the first hinge plate 341 drives the second hinge plate 343 to expand outward. The radial dimension of the tensioning assembly 3 continuously increases until the cylinder liner clamping plate 4 on the second hinge plate 343 contacts the inner wall of the cylinder liner and clamps the cylinder liner, thereby realizing the rapid gripping of the cylinder liner.

[0026] Furthermore, the cylinder body 1 is provided with a quick connector 5 for connecting the air pipe for controlling the cylinder.

[0027] In this embodiment, quick connectors 5 are installed on both the outer surface of the head and the bottom surface of the tail of the cylinder body 1, so that the quick connectors 5 can be quickly connected to the air pipe controlling the cylinder, thus realizing the quick installation of the device.

[0028] Furthermore, a cotter pin 6 is inserted at the tail of the hinge pin 342.

[0029] This device uses a hinge pin 342 to achieve the hinge connection between the first hinge seat 31, the second hinge seat 32, the third hinge seat 33, the first hinge plate 341, and the second hinge plate 343. In order to prevent the hinge pin 342 from coming loose during operation, this embodiment provides a through hole at the tail end of the hinge pin 342 (the end through which the hinge pin 342 passes) and inserts a cotter pin 6 into the through hole, thereby preventing the hinge pin 342 from coming loose during operation.

[0030] Furthermore, the head of the cylinder rod 2 is provided with a first limiting boss 21 for limiting the second hinge seat 32, the cylinder rod 2 on the front side of the second hinge seat 32 is provided with a first fixing nut 7, the middle part of the cylinder rod 2 is provided with a second limiting boss 22 for limiting the third hinge seat 33, and the cylinder rod 2 on the front side of the third hinge seat 33 is provided with a second fixing nut 8.

[0031] In this embodiment, a first limiting boss 21 is provided at the head of the cylinder rod 2. After the second hinge seat 32 is precisely fitted onto the head of the cylinder rod 2, the first limiting boss 21 can limit the second hinge seat 32 to prevent relative movement during operation. In addition, a first fixing nut 7 is threadedly fixedly installed on the cylinder rod 2 on the front side of the second hinge seat 32 to firmly fix the second hinge seat 32. A second limiting boss 22 is provided in the middle of the cylinder rod 2. After the third hinge seat 33 is precisely fitted onto the middle of the cylinder rod 2, the second limiting boss 22 can limit the third hinge seat 33 to prevent relative movement during operation. In addition, a second fixing nut 8 is threadedly fixedly installed on the cylinder rod 2 on the front side of the third hinge seat 33 to firmly fix the third hinge seat 33.

[0032] In operation, the robotic arm first drives the cylinder to move rapidly to the cylinder liner position. Then, the cylinder rod 2 is driven to move outward from the cylinder body 1. The cylinder rod 2 drives the second hinge seat 32 and the third hinge seat 33 to move away from the cylinder body 1. The second hinge seat 32 and the third hinge seat 33 drive one end of the first hinge plate 341 to move away from the cylinder body 1, so that the other end of the first hinge plate 341 drives the second hinge plate 343 to retract towards the center. The radial dimension of the tensioning assembly 3 continuously decreases until the entire tensioning assembly 3 and the cylinder liner clamping plate 4 can be inserted into the cylinder liner. Then, the cylinder rod 2 is driven to move outward from the cylinder body 1. The cylinder body 1 moves inside, and the cylinder rod 2 drives the second hinge seat 32 and the third hinge seat 33 to move closer to the cylinder body 1. The second hinge seat 32 and the third hinge seat 33 drive one end of the first hinge plate 341 to move closer to the cylinder body 1, so that the other end of the first hinge plate 341 drives the second hinge plate 343 to expand outward. The radial dimension of the tensioning assembly 3 continuously increases until the cylinder liner clamping plate 4 on the second hinge plate 343 contacts the inner wall of the cylinder liner and clamps the cylinder liner. Finally, the robotic arm is controlled to move the clamped cylinder liner to the designated position to achieve rapid gripping of the cylinder liner, thereby improving the efficiency of die casting engine cylinder blocks.
