Description

Technical Field

[0001] The utility model relates to the technical field of cylinder sleeve grabbing, in particular to an automatic cylinder sleeve grabbing mechanism. Background Art

[0002] The traditional conveying method during cylinder liner processing is to use a belt conveyor or a roller conveyor to transport the cylinder liner to the next processing step, where it is grabbed by humans or robots. Commonly used robots directly extend the pneumatic clamp into the inner hole of the workpiece, then open it, and extract the workpiece by the friction between the clamp and the inner wall of the workpiece. The heavier the workpiece, the greater the required expansion force. Too much expansion force can cause the cylinder liner to deform, thereby destroying the geometric accuracy of the workpiece such as roundness and cylindricity after honing. This type of grasping method can be used in the rough machining state, but using this type of grasping method after fine honing may cause certain irreparable damage to the cylinder liner. If the expansion force is reduced due to consideration of workpiece deformation, there is a risk of the workpiece slipping.

[0003] Therefore, a cylinder sleeve automatic grabbing mechanism is needed to overcome the occurrence of the above problems. Utility Model Content

[0004] In order to solve the above problems, an embodiment of the utility model provides a cylinder sleeve automatic grasping mechanism, which achieves the purpose of solving the problems raised in the background technology.

[0005] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: an automatic grasping mechanism for a cylinder sleeve, comprising a telescopic mechanical arm, a clamping cylinder arranged on the telescopic mechanical arm, and a clamping claw arranged on the clamping claw cylinder, wherein a limit block for supporting the cylinder sleeve is arranged at the bottom of the clamping claw.

[0006] As a further improvement of the above technical solution:

[0007] The limiting block is wedge-shaped.

[0008] The top inclined surface of the limit block is a smooth surface.

[0009] The top inclined surface of the limit block is an arc surface.

[0010] The bottom of the limiting block is an inclined surface.

[0011] A rubber pad is fixedly connected to one side of the clamping claw close to the cylinder sleeve.

[0012] The clamping jaw comprises a fixed block connected to the clamping jaw cylinder, a screw rod fixedly connected to the end of the fixed block, and an extension block threadedly connected to the outside of the screw rod.

[0013] The beneficial effects of the embodiments of the utility model are:

[0014] In actual use, when the clamp is inserted into the cylinder liner, the limit block is inserted into the bottom of the cylinder liner, thereby supporting the cylinder liner through the limit block. Therefore, when the clamp grabs the cylinder liner, it does not need excessive expansion force, thereby avoiding damage to the cylinder liner caused by excessive expansion force.

[0018] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0019] See also Figure 1 to Figure 2 The embodiment of the utility model discloses an automatic grasping mechanism for a cylinder sleeve, comprising a telescopic mechanical arm 1, a gripper cylinder 2 arranged on the telescopic mechanical arm 1, a gripper 3 arranged on the gripper cylinder 2, and a limit block 4 for supporting the cylinder sleeve is arranged at the bottom of the gripper 3; the telescopic mechanical arm 1 and the gripper cylinder 2 are both mature technologies in the art and have nothing to do with the technical problem solved by the present application, so the specific structures of the telescopic mechanical arm 1 and the gripper cylinder 2 are not further described;

[0020] The telescopic mechanical arm 1 drives the clamping cylinder 2 to move, and the clamping cylinder 2 controls the clamping jaw 3 to open and close. After the clamping jaw 3 is closed, the clamping jaw 3 is inserted into the cylinder sleeve, and then the clamping jaw 3 is opened, so that the clamping jaw 3 clamps the cylinder sleeve to grab the cylinder sleeve;

[0021] In actual use, when the clamping jaws 3 are inserted into the cylinder liner, the limit block 4 is inserted into the bottom of the cylinder liner, thereby supporting the cylinder liner through the limit block 4. Therefore, when the clamping jaws 3 grab the cylinder liner, they do not need excessive expansion force, thereby avoiding damage to the cylinder liner caused by excessive expansion force.

[0022] As a further illustration of this application:

[0023] The limiting block 4 is wedge-shaped, that is, one end of the limiting block 4 is a pointed end, so that the limiting block 4 is easy to be clamped into the bottom of the cylinder sleeve.

[0024] As a further illustration of this application:

[0025] The top inclined surface of the limit block 4 is a smooth surface. After the limit block 4 is inserted into the bottom of the cylinder sleeve, the cylinder sleeve slides on the limit block 4. The smooth surface can reduce the friction between the limit block 4 and the cylinder sleeve.

[0026] As a further illustration of this application:

[0027] The top inclined surface of the limit block 4 is an arc surface, which reduces the contact area between the cylinder sleeve and the limit block 4, thereby reducing the friction between the limit block 4 and the cylinder sleeve.

[0028] As a further illustration of this application:

[0029] The bottom of the limit block 4 is an inclined surface. When the cylinder liner is grabbed, the cylinder liner is usually placed on a certain plane (such as a conveyor belt). When the bottom of the limit block 4 is an inclined surface, the contact between the limit block 4 and the plane is only the front end of the limit block 4, thereby reducing the friction between the limit block 4 and the plane.

[0030] As a further illustration of this application:

[0031] A rubber pad 5 is fixedly connected to one side of the clamping jaw 3 close to the cylinder sleeve, so as to increase the friction between the clamping jaw 3 and the cylinder sleeve and prevent the clamping jaw 3 from scratching the cylinder sleeve.

[0032] As another embodiment of the present application:

[0033] The clamping jaw 3 includes a fixed block 31 connected to the clamping jaw cylinder 2, a screw rod 32 fixedly connected to the end of the fixed block 31, and an extension block 33 threadedly connected to the outside of the screw rod 32; in actual use, by rotating the extension block 33, the extension block 33 is rotated on the screw rod 32, thereby changing the distance between the extension block 33 and the fixed block 31, that is, changing the overall length of the clamping jaw 3, so that the clamping jaw 3 can be used for grasping cylinder sleeves of different lengths.
