[0001] The utility model relates to the technical field of hangers, in particular to an engine cylinder head hanger. Background Art

[0002] The engine cylinder head is an important part of the engine. It is installed on the cylinder block. Its main function is to seal the cylinder from the top and form a combustion chamber. When assembling and processing the engine cylinder head, due to its own weight, it needs to be lifted with the help of a hoist. The commonly used hoist is a truss manipulator.

[0003] The truss manipulator is a fully automatic industrial equipment based on the right-angle X, Y, Z three-coordinate system. It is used to adjust the workpiece position or realize the trajectory movement of the workpiece. Its control core is realized by the industrial controller. The controller analyzes and processes various input signals, makes logical judgments, and uses two clamping arms to clamp the engine cylinder head.

[0004] With respect to the existing related technologies, it is believed that the following defects exist: when the clamping arm of the existing truss manipulator contacts the engine cylinder head, its contact surface is mostly made of hard iron material, and the engine cylinder head is a precision equipment, which makes it very easy to scratch the surface of the engine cylinder head during clamping and transportation, causing damage to the engine cylinder head; therefore, an engine cylinder head hoist is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem raised in the background technology, the utility model provides an engine cylinder head hanger.

[0006] The technical solution adopted by the utility model to solve its technical problems is: an engine cylinder head hanger described in the utility model includes a truss manipulator, the bottom of the truss manipulator is connected to two clamping arms through a screw, the two clamping arms are fixedly installed with a clamping plate on the side close to each other, and a plurality of auxiliary blocks made of rubber material are fixedly installed on the side close to each other of the two clamping plates, a plurality of sliding grooves are provided on the side of the clamping plate close to the auxiliary block, a slider is slidably connected inside the sliding groove, a protective sleeve of rubber material is provided on the surface of the slider, an elastic ball is fixedly installed inside the sliding groove, and one end of the elastic ball is fixedly connected to the slider.

[0007] Furthermore, a groove is provided on the surface of the sliding block, the protective sleeve is located in the groove, and one end of the sliding block away from the sliding groove is made of rubber material.

[0008] Furthermore, the slider and the slide groove are sealed and slidably connected, the surface of the elastic ball is provided with a shrinkage hole, the top of the splint is fixedly installed with an air pipe connected to the inside of the slide groove, the surface of the air pipe is fixedly installed with a bracket, and the bottom of the bracket is fixedly connected to the splint.

[0009] Furthermore, one end of the air blowing pipe is rotatably connected to an end cover via a torsion spring, and a rubber plug is fixedly mounted on a side of the end cover close to the air blowing pipe.

[0010] Furthermore, an arc-shaped fixing rod is fixedly mounted on a side of the end cover away from the air blowing pipe, an arc-shaped sleeve is fixedly mounted on the surface of the air blowing pipe, and an arc-shaped fixing groove is formed at one end of the sleeve.

[0011] Furthermore, the fixing groove gradually increases from an end close to the air blowing pipe to an end away from the air outlet pipe, and the fixing rod is made of rubber.

[0012] The utility model is beneficial in that:

[0013] 1. When the truss manipulator of the utility model is ready to clamp the engine cylinder head, the rubber protective sleeve is first installed into the groove of the slider, and then the two clamping arms are moved to both sides of the engine cylinder head. At this time, the two clamping arms are started, and the two clamping arms are moved toward the direction of the engine cylinder head with the clamping plate, so that the rubber end of the slider contacts the engine cylinder head. Since there are many holes on the surface of the engine cylinder head, part of the slider will enter the holes of the engine cylinder head, while the slider that has not entered the holes of the engine cylinder head will be squeezed to slide and shrink into the slide groove, so that the rubber auxiliary block on the clamping plate contacts the surface of the engine cylinder head. When the clamping of the engine cylinder head is completed, the truss manipulator will move up with the engine cylinder head. Since the rubber auxiliary block and the protective sleeve are in contact with the engine cylinder head, the engine cylinder head will not be scratched. The engine cylinder head can be protected while the clamping plate and the slider can be protected. The protective sleeve is placed in the groove of the slider to facilitate quick replacement after damage.

[0014] 2. When part of the slider contacts and is squeezed against the surface of the engine cylinder head, the slider will slide and shrink into the slide groove. At this time, the gas in the elastic ball will be squeezed into the slide groove and into the air blowing pipe along with the gas in the slide groove, and the end cover at the end of the air blowing pipe will be pushed open, so that the gas will blow toward the engine cylinder head and the clamping plate. After the end cover is pushed up, it will be inserted into the fixing groove of the sleeve with the arc-shaped fixing rod. Since the positioning rod is made of rubber and the fixing groove gradually increases from the end close to the air blowing pipe to the end away from the air outlet pipe, the arc-shaped fixing rod will be clamped, so that the end cover will not be reset temporarily, and the end cover will become inclined. At the same time, the inclined end cover can guide the airflow well, so that the airflow can be accurately blown toward the engine cylinder head and the clamping plate, the surfaces of both will be cleaned, the residual impurities will be reduced, scratches during clamping will be prevented, and subsequent clamping work will be convenient. When the clamping work is completed, the engine cylinder head is removed, and the end cover is slowly reset under the action of the torsion spring, so that the gas can enter the slide groove and the elastic ball through the blowing pipe, which is convenient for the next use.

[0024] During operation, when the truss manipulator 1 is ready to clamp the engine cylinder head, the rubber protective sleeve 7 is first installed into the groove of the slider 6, and then the two clamping arms 2 are moved to both sides of the engine cylinder head. At this time, the two clamping arms 2 are started, and the two clamping arms 2 are moved toward the direction of the engine cylinder head with the clamping plate 3, so that the rubber end of the slider 6 contacts the engine cylinder head. Since there are many holes on the surface of the engine cylinder head, part of the slider 6 will enter the holes of the engine cylinder head, while the slider 6 that has not entered the holes of the engine cylinder head will be squeezed to slide and shrink into the slide groove 5, so that the rubber auxiliary block 4 on the clamping plate 3 contacts the surface of the engine cylinder head. When the clamping of the engine cylinder head is completed, the truss manipulator 1 will move up with the engine cylinder head. Since the rubber auxiliary block 4 and the protective sleeve 7 are in contact with the engine cylinder head, the engine cylinder head will not be scratched. The engine cylinder head can be protected while the clamping plate 3 and the slider 6 can be protected. The protective sleeve 7 is placed in the groove of the slider 6 to facilitate quick replacement after damage.

[0025] The slider 6 and the slide groove 5 are sealed and slidably connected, a shrinkage hole is opened on the surface of the elastic ball 8, an air blowing pipe 9 connected to the inside of the slide groove 5 is fixedly installed on the top of the splint 3, a bracket 10 is fixedly installed on the surface of the air blowing pipe 9, and the bottom of the bracket 10 is fixedly connected to the splint 3.

At this time, start the two clamping arms 2, and let the two clamping arms 2 move with the clamping plate 3 in the direction of the engine cylinder head, so that the rubber end of the slider 6 contacts the engine cylinder head. Since there are many holes on the surface of the engine cylinder head, part of the slider 6 will enter the holes of the engine cylinder head, while the slider 6 that has not entered the holes of the engine cylinder head will be squeezed to slide and shrink into the slide groove 5, so that the rubber auxiliary block 4 on the clamping plate 3 contacts the surface of the engine cylinder head. When the clamping of the engine cylinder head is completed, the truss manipulator 1 will move up with the engine cylinder head. Since the rubber auxiliary block 4 and the protective sleeve 7 are in contact with the engine cylinder head, the engine cylinder head will not be scratched. While protecting the engine cylinder head, the clamping plate 3 and the slider 6 can also be protected, and the protective sleeve 7 is placed in the groove of the slider 6 to facilitate quick replacement after damage.

[0029] When part of the slider 6 contacts and is squeezed with the surface of the engine cylinder head, it will slide and shrink into the slide groove 5.
