Description

Technical Field

[0001] This utility model relates to the field of engine manufacturing technology, specifically to a release device for a cylinder head conveyor line. Background Technology

[0002] In industrial production, especially in the manufacturing of heavy machinery such as automobiles or ship engines, the cylinder head is a key component, and its production and assembly process requires extremely precise control. The cylinder head conveyor release device is primarily designed to ensure that the cylinder heads are accurately delivered to their designated work positions at the correct time for subsequent operations such as assembly, inspection, or processing. This prevents collisions or stacking caused by multiple cylinder heads entering the same workstation simultaneously, ensuring operator safety and the normal operation of the equipment.

[0003] Existing technologies generally use planar baffle structures to block heavy cylinder heads. However, the cylinder head ends usually have irregular structures such as process bosses, lifting holes, and oil passages, which result in a small contact area with the planar baffle structure, uneven contact stress distribution, and unstable contact state. This can easily cause the cylinder head to tilt due to uneven load. In addition, heavy cylinder heads have a large impact force, and their rigid contact with the baffle structure is easily worn.

[0004] To address these issues, a cylinder head delivery line release device is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a release device for cylinder head conveyor lines, which solves the problems of small contact area and unstable contact state between the existing planar release device and the cylinder head end, which easily causes cylinder head to be unbalanced and tilted.

[0006] This utility model achieves the above objectives through the following technical solutions: A release device for a cylinder head conveyor line, located in a cavity below the conveyor line rollers, includes: A flat baffle is installed between adjacent conveyor rollers on the conveyor line, and can be raised and lowered. A drive mechanism is used to drive the planar baffle to rise and fall, so as to switch between blocking and allowing passage; An airbag is fixedly mounted on the side of the flat baffle and is used to completely cover the end of the cylinder head when inflated. A limiting frame, disposed on the planar baffle and arranged circumferentially around the airbag, is used to limit excessive deformation of the airbag. The limiting frame includes multiple enclosures and a second driving member corresponding to each enclosure. One side of each enclosure is hinged to a flat baffle, and the other side is hinged to the second driving member. The second driving member is used to drive the enclosure to unfold to form a constraint frame or to retract to attach to the surface of the flat baffle.

[0007] As a further optimization of this utility model, the driving mechanism includes a first driving component and a fixed seat for mounting the first driving component; two symmetrically distributed guide rods are fixedly provided at the bottom of the planar baffle, and the guide rods movably pass through the top of the fixed seat.

[0008] As a further optimization of this utility model, the side panel facing the airbag is provided with multiple evenly distributed flexible support ribs.

[0009] As a further optimization of this utility model, the back of the airbag is provided with a plurality of first springs evenly distributed in a dot matrix pattern.

[0010] As a further optimization of this utility model, it also includes a measuring component for real-time detection of the relative position between the cylinder head and the release device, the measuring component being disposed in a slot opened at the top of the flat baffle.

[0011] As a further optimization of this utility model, the measuring component includes a mounting base fixedly disposed at the top of the slot, a movable rod movably passing through the mounting base, a wedge-shaped seat fixedly disposed at the top of the movable rod, and a photoelectric sensor embedded in the groove of the wedge-shaped seat; an end block is fixedly disposed at the bottom end of the movable rod, and a second spring is sleeved on the movable rod between the end block and the mounting base.

[0012] As a further optimization of this utility model, the internal chamber of the airbag is configured as a partitioned structure, including three independent left side chamber, right side chamber and middle chamber; the area ratio of the left side chamber, right side chamber and middle chamber is 1:1.5:1.

[0013] The beneficial effects of this utility model are as follows: 1. This utility model is applicable to the conveying and release of heavy cylinder heads. It adopts a contour-matching contact structure composed of a flat baffle, an airbag, and a limiting frame. Through the adaptive wrapping of the complex geometric features of the cylinder head end by the airbag, a large-scale, continuous flexible contact is achieved, which significantly increases the effective contact area, reduces local pressure, and avoids indentation or coating peeling on key surfaces. At the same time, the airbag, as an elastic buffer medium, absorbs kinetic energy through controllable deformation during the cylinder head impact, effectively suppressing the structural impact and noise caused by rigid collision.

[0014] 2. The airbag of this utility model adopts a partitioned chamber design, which enables precise control of the expansion behavior of each area, better adapts to the complex contour of the cylinder head end face, provides a more uniform pressure distribution, and solves the problem that the cylinder head may be tilted during overall inflation.

[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0018] Example 1 To address the issue that existing technologies typically use planar baffle structures to block heavy cylinder heads, but cylinder head ends often have irregular structures such as process bosses, lifting holes, and oil passages, resulting in a small contact area and unstable contact with the planar baffle structure, easily causing cylinder head tilting due to uneven load, and the significant impact force of heavy cylinder heads making the rigid contact with the baffle structure easily damaged, please refer to [reference needed]. Figures 1-3 This utility model provides a release device for a cylinder head conveyor line, located in a cavity below the conveyor line rollers, comprising: A flat baffle 1 is vertically mounted between adjacent conveyor rollers 2 on the conveyor line; The drive mechanism 3 is used to drive the flat baffle 1 to rise and fall, so as to switch between blocking and allowing passage; Airbag 4 is fixedly installed on the side of the flat baffle 1. It is used to completely wrap the end of the cylinder head when it is inflated, so as to reduce the impact on the flat baffle 1 and prevent the cylinder head from tilting due to uneven load. Airbag 4 adopts an industrial-grade sealing bladder (such as rubber bladder, TPU material) and can withstand the contact force of heavy workpieces. Multiple first springs 401 are evenly distributed in a dot matrix on the back of airbag 4. The limiting frame 5 is disposed on the flat baffle 1 and arranged around the airbag 4 in a circumferential manner to limit the excessive deformation of the airbag 4.

[0019] The limiting frame 5 includes multiple enclosures 501 and a second driving member 502 corresponding to each enclosure 501. One side of each enclosure 501 is hinged to a flat baffle 1, and the other side is hinged to the second driving member 502. The second driving member 502 is used to drive the enclosure 501 to unfold to form a constraint frame or to retract to attach to the surface of the flat baffle 1. Multiple evenly distributed flexible support ribs 503 are provided on the side of the enclosure 501 facing the airbag 4. The flexible support ribs 503 can be made of elastic plastic strips or elastic rubber strips, etc. The limiting frame 5 restricts the excessive deformation of the airbag 4 in all directions, thereby improving the load-bearing capacity, directional expansion controllability, and service life of the airbag 4, making the entire release device more reliable and safe.

[0020] The drive mechanism 3 includes a first drive component 301 and a fixed base 302 for mounting the first drive component 301. The first drive component 301 includes, but is not limited to, a hydraulic cylinder, an electric screw lifting module, or a pneumatic actuator. Two symmetrically distributed guide rods 101 are fixedly provided at the bottom of the flat baffle 1. The guide rods 101 movably pass through the top of the fixed base 302, forming a guiding and cooperating mechanism. The release device adopts a lifting structure and is normally hidden in the cavity below the conveyor roller. When it is necessary to block the cylinder head, the first drive component 301 drives the flat baffle 1 to rise from between two adjacent conveyor rollers 2, protruding 30-50mm from the roller surface. When releasing, it retracts in the opposite direction without interfering with the normal passage of the cylinder head.

[0021] To improve the intelligence level and operational reliability of the release device, such as Figure 2 , Figure 4 As shown, it also includes a measuring component 6 for real-time detection of the relative position between the cylinder head and the release device. The measuring component 6 is located in a slot 102 opened at the top of the flat baffle 1.

[0022] The measuring component 6 includes a mounting base 601 fixedly mounted on the top of the slot 102, a movable rod 602 movably passing through the mounting base 601, a wedge-shaped seat 603 fixedly mounted on the top of the movable rod 602, and a photoelectric sensor 604 embedded in the groove of the wedge-shaped seat 603. The detection optical axis of the photoelectric sensor 604 is parallel to the cylinder head conveying direction and is used to continuously measure the distance between the front end face of the cylinder head and the release device. An end block 605 is fixedly mounted on the bottom end of the movable rod 602. A second spring 606 is sleeved on the movable rod 602 between the end block 605 and the mounting base 601. One end of the second spring 606 is fixedly connected to the end block 605, and the other end is fixedly connected to the mounting base 601.

[0023] The flat baffle 1 is in a lowering or raising preparation state. The measuring component 6 remains convex under the elastic force of the second spring 606. The wedge-shaped seat 603 at its top and the photoelectric sensor 604 embedded therein protrude above the surface of the conveyor roller 2, facing the travel path of the cylinder head. At this time, the photoelectric sensor 604 continuously emits a detection beam to collect the distance data between the front end of the cylinder head and the baffle in real time. When the cylinder head moves along the conveyor line to approach the release device, it triggers actions such as the flat baffle 1 rising and the airbag 4 inflating. During the release process, the bottom of the cylinder head first contacts the measuring component. The wedge-shaped seat 603 at the top of component 6 has an inclined guide surface. During the movement of the cylinder head, the movable rod 602 can be smoothly pushed to overcome the elastic force of the second spring 606, so that the entire measuring component 6 can be vertically retracted into the space below the transmission roller 2 along the slot 102, achieving unobstructed passage. After the cylinder head has completely passed through, the pressure acting on the wedge-shaped seat 603 is released, the second spring 606 releases its stored energy, and drives the movable rod 602, end block 605 and upper structure to rebound synchronously, so that the measuring component 6 returns to its original convex state, ready to enter the next detection cycle.

[0024] In the initial state, the flat baffle 1 is in the descending position, housed in the cavity below the conveyor rollers, and the airbag 4 is in a depressurized and contracted state. Each surrounding plate 501 retracts under the action of the second drive component 502, adhering to the surface of the flat baffle 1. The overall structure does not interfere with the conveying path. When the measuring component 6 detects a signal that the cylinder head is about to arrive, the drive mechanism 3 starts, causing the flat baffle 1 to rise vertically, passing through the gap between adjacent conveyor rollers 2. Then, the second drive component 502 actuates, pushing each surrounding plate 501 outward around the hinge point, forming a constraint frame around the airbag 4. After the surrounding plates 501 are fully extended, the air supply system introduces compressed gas into the airbag 4 for pre-inflation (e.g., inflating to 0.1-0.2 MPa). The airbag 4 inflates slightly, entering a contact state. As the cylinder head continues to move forward, its end gradually contacts the airbag 4. The air supply system continues to supply compressed gas to the airbag 4, causing the airbag 4 to continuously inflate and flexibly conform to the irregular contour of the cylinder head end. Under the constraint boundary formed by the surrounding plate 501, the radial deformation of the airbag 4 is limited, and the energy is mainly concentrated in the axial contact direction, thereby achieving uniform and stable flexible contact, effectively absorbing impact kinetic energy, and preventing off-center loading. When releasing, the airbag 4 depressurizes, and the second drive component 502 drives in the opposite direction, causing each surrounding plate 501 to retract to the state of conforming to the flat baffle 1. Finally, the drive mechanism 3 drives the flat baffle 1 to descend and reset, and the cylinder head passes smoothly under the action of the transmission power.

[0025] Example 2 Based on Example 1, in order to better adapt to the complex contours of the cylinder head end face, such as bolt hole groups, reinforcing ribs, oil passages, etc., and to avoid the problem of cylinder head misalignment that may occur during overall inflation, such as... Figure 5 As shown, the internal chambers of the airbag 4 are designed with a partitioned structure, including three independent left chamber, right chamber, and middle chamber; the area ratio of the left chamber, right chamber, and middle chamber is 1:1.5:1. Each chamber is connected to an air pump through an independent air supply line, and a solenoid valve is installed on the air supply line to control the inflation and deflation process of each chamber. Each chamber is equipped with a pressure sensor to monitor the air pressure status in real time.

[0026] During inflation, the left, right, and middle chambers all maintain a certain pre-inflation pressure (e.g., around 0.1 MPa) to ensure that the airbag 4 is basically formed. When the cylinder head end approaches, the left and right chambers are inflated first (pressurized to around 0.4 MPa) so that the airbag 4 gradually surrounds the cylinder head. The expansion of the side chambers achieves lateral centering of the cylinder head. After the pressure on both sides stabilizes, the middle chamber is inflated (pressurized to around 0.4 MPa). The expansion of the middle area completes the tight fit, forming a synergistic effect of positioning first and then tightening. By inflating in stages, it can better adapt to the complex contour of the cylinder head end face, provide a more uniform pressure distribution, and solve the problem of cylinder head tilting that may occur during overall inflation.

[0027] Example 3 Based on Example 1, such as Figure 6 As shown, the internal chambers of the airbag 4 adopt a ring-shaped partitioned layout surrounding the center, including a central chamber and side chambers arranged around it.

[0028] Example 4 Based on Example 1, such as Figure 7 As shown, the internal chambers of the airbag 4 adopt a strip-shaped partitioned layout, including multiple longitudinal strip chambers distributed at equal intervals along the lateral direction.

[0029] Example 5 Based on Example 1, such as Figure 8 As shown, the internal chambers of the airbag 4 adopt a grid-like partitioned layout, including multiple micro chambers.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
