Description

Technical Field

[0001] This disclosure relates to the field of engine testing technology, and more specifically, to a cylinder head inspection bench. Background Technology

[0002] On the cylinder head assembly line in an automotive engine assembly workshop, there is a repair station for defective cylinder heads. In related technologies, when repairing cylinder head component assembly defects, the defective components must be manually removed and reinstalled.

[0003] During the installation of the cylinder head valve lock plate, one end of the valve stem passes through the cylinder head. Since the elastic element and the lock plate need to be installed on the part of the valve stem located inside the cylinder head, the valve stem is prone to slipping out of the hole on the cylinder head under the action of gravity, making the installation of the lock plate difficult. Utility Model Content

[0004] The purpose of this disclosure is to provide a cylinder head inspection bench to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this disclosure provides a cylinder head inspection platform, including a main body, a fixing member, and a support plate. The lower end of the main body is fixed to the ground, and the upper end of the main body forms a support platform. The fixing member and the support plate are both disposed on the support platform. The fixing member is used to releasably fix the cylinder head located on the support plate.

[0006] The support plate has multiple abutment protrusions on the side facing away from the support platform, and the multiple abutment protrusions are used to abut the valves of the cylinder head.

[0007] Optionally, a groove is formed on the side of the support plate facing away from the support platform, and a plurality of the abutting protrusions are disposed in the groove.

[0008] Optionally, the projection of the groove onto the support platform is a rounded rectangle.

[0009] Optionally, the support plate includes a first part and a second part connected along a first direction, wherein the dimension of the second part along a second direction is greater than the dimension of the first part along the second direction.

[0010] Optionally, the second part includes a connected expanding section and a horizontal section, the expanding section being disposed between the first part and the horizontal section.

[0011] Optionally, the number of the abutment protrusions is the same as the number of valves in the cylinder head.

[0012] Optionally, the support plate is provided with grip handles on both sides along the first direction.

[0013] Optionally, the cylinder head inspection platform further includes a limiting component, which is disposed on the support platform and forms a limiting area. The support plate is disposed in the limiting area, and the limiting area is used to place the cylinder head.

[0014] Optionally, the limiting component includes a plurality of limiting blocks, which are detachably disposed on the support platform, and the plurality of limiting blocks enclose the limiting area.

[0015] The plurality of limiting blocks include two first limiting blocks located in a first direction and one second limiting block located in a second direction, wherein the first direction is perpendicular to the second direction.

[0016] Optionally, the limiting assembly further includes a cylinder head base, which is detachably mounted on the support platform, and the support plate is detachably disposed on the cylinder head base.

[0017] Through the above technical solution, the abutment protrusion of the support plate ensures that the valves remain within the valve holes on the cylinder head, thereby allowing the valve stems to be positioned conveniently for the installation of valve springs and locking plates, improving installation convenience. Simultaneously, when the cylinder head is placed on the support plate, the fixing components provide force to secure the cylinder head to the support plate, preventing displacement due to force. This enhances the stability and ease of cylinder head installation, reducing the probability of injury to the cylinder head or personnel during installation.

[0018] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0026] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" are generally defined based on the normal operating state of the cylinder head inspection bench. They are used only for the convenience of describing this disclosure and for simplification, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or a specific orientational construction and operation, and therefore should not be construed as a limitation of this disclosure. "Inner" and "outer" refer to the inside and outside of the outline of the corresponding component. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0028] like Figures 1 to 3 As shown, this disclosure provides a cylinder head inspection bench 100, including a main body 1, a fixing member 2, and a support plate 3. The lower end of the main body 1 is fixed to the ground, and the upper end of the main body 1 forms a support platform 11. The fixing member 2 and the support plate 3 are both disposed on the support platform 11. The fixing member 2 is used to releasably fix the cylinder head located on the support plate 3. A plurality of abutting protrusions 31 are formed on the side of the support plate 3 facing away from the support platform 11. The plurality of abutting protrusions 31 are used to abut the valves of the cylinder head.

[0029] When reinstalling components on the cylinder head, the cylinder head can first be placed on the support plate 3 on the support platform 11, so that the multiple abutment protrusions 31 correspond one-to-one with the multiple valves on the cylinder head, so that the valves are kept in contact with the valve holes of the cylinder head, that is, one end of the valve stem is completely within the space formed by the cylinder head. When the cylinder head is placed with the opening facing upward on the support plate 3, the valve stem is exposed, so that the valve spring and locking plate can be installed on the valve stem. At the same time, the cylinder head is fixed in the current position by the fastener 2.

[0030] Through the above technical solution, the abutment protrusion 31 of the support plate 3 can keep the valve always located in the valve hole on the cylinder head, thereby allowing the valve stem to be kept in a position that facilitates the installation of the valve spring and locking plate, improving the convenience of installation. At the same time, when the cylinder head is placed on the support plate 3, the fixing member 2 can provide force to fix the cylinder head on the support plate 3, preventing the cylinder head from shifting due to force, thereby improving the stability of the cylinder head and the convenience of installation during component installation, and reducing the probability of cylinder head or personnel injury during installation.

[0031] This disclosure does not limit the specific structure of the fastener 2. In one embodiment of this disclosure, the fastener 2 can be a rotating buckle. One end of the buckle is rotatably mounted on the main body 1, and the other end of the buckle is detachably engaged on the side of the cylinder head away from the bearing plate 3, so as to fix the cylinder head on the bearing plate 3.

[0032] In another embodiment provided in this disclosure, the fixing member 2 can be a vertical quick clamp, wherein the clamping force of the clamp can be 500 kg.

[0033] Optionally, such as Figure 2 As shown, a groove 32 is formed on the side of the support plate 3 facing away from the support platform 11, and multiple abutment protrusions 31 are disposed within the groove 32. Since the cylinder head shapes of different engine models vary, in some engine cylinder heads, when the valve is located in the valve hole of the cylinder head, the valve head will protrude beyond the outer surface of the cylinder head. By providing the groove 32 on the side of the support plate 3 facing away from the support platform 11, when the cylinder head is placed on the support plate 3, the groove 32 can accommodate the portion of the valve head protruding beyond the outer surface of the cylinder head, thus ensuring that the cylinder head can be placed stably on the support plate 3 without the valve interfering with the support plate 3 and causing the cylinder head to be unstable. Furthermore, by placing the abutment protrusions 31 within the groove 32, when the valve head is located in the groove 32, the abutment protrusions 31 can also abut the valve, thus facilitating the installation of the valve spring and locking plate.

[0034] Optionally, such as Figure 2As shown, the projection of the groove 32 onto the support platform 11 is a rounded rectangle. Setting the projection of the groove 32 onto the support platform 11 as a rounded rectangle serves two purposes: firstly, it reduces the number of right angles in the groove 32, thereby reducing stress concentration areas and improving the overall strength of the support plate 3; secondly, the rounded rectangle also reduces the processing difficulty of the groove 32, thus reducing the processing cost of the support plate 3.

[0035] To improve load-bearing capacity, optionally, such as Figure 2 As shown, the support plate 3 includes a first portion 33 and a second portion 34 connected along a first direction. The dimension of the second portion 34 along a second direction is larger than the dimension of the first portion 33 along the second direction. Since the engine cylinder head is designed according to the distribution of internal parts, it is not a perfectly regular shape. By setting the dimension of the second portion 34 of the support plate 3 along the second direction to be larger than the dimension of the first portion 33 along the second direction, the second portion 34 can support the wider portion of the cylinder head along the second direction when the support plate 3 supports the cylinder head, thereby providing more comprehensive support for the cylinder head and improving its stability.

[0036] Optionally, such as Figure 2 As shown, the second part 34 includes a connected expanding section 341 and a horizontal section 342, with the expanding section 341 positioned between the first part 33 and the horizontal section 342. Using the expanding section 341 to connect the first part 33 and the horizontal section 342 serves two purposes: firstly, it reduces the angle between the first part 33 and the horizontal section 342, thereby reducing stress concentration at the connection and improving the structural strength of the support plate 3; secondly, as the second part 34, the expanding section 341 also increases the bearing area of ​​the support plate 3, thereby increasing the number of cylinder head models that the support plate 3 can support, allowing more cylinder head models to be placed stably on the support plate 3.

[0037] Optionally, such as Figure 2 As shown, the number of abutment protrusions 31 is the same as the number of valves in the cylinder head. Since the cylinder head includes multiple valves, the valve stems of all valves must remain exposed during installation. Setting the number of abutment protrusions 31 to be the same as the number of valves ensures that the valve stems are in an easy-to-install state when installing different valves, thus accommodating more installation scenarios.

[0038] To reduce the machining difficulty of the abutment protrusion 31, the abutment protrusion 31 may optionally be a bolt, the head of which is used to abut against the valve of the cylinder head.

[0039] To further restrict the position of the cylinder head, alternatively, such as Figure 1 and Figure 3As shown, the cylinder head inspection bench 100 also includes a limiting component 4. The limiting component 4 is disposed on the support platform 11 and forms a limiting area 41. The support plate 3 is disposed within the limiting area 41, which is used to place the cylinder head. When reinstalling defective parts on the cylinder head, forces in different directions need to be applied to the cylinder head. The fixing member 2 can restrict the position of the cylinder head in the vertical direction, while the horizontal restriction mainly relies on the static friction between the cylinder head and the support platform 11. The limiting component 41 forms a limiting area on the support platform 11, and the support plate 3 is disposed within the limiting area 41. When the cylinder head is placed on the support plate 3, the limiting component 4 can provide horizontal restriction, so that the cylinder head will not shift due to force during the disassembly and assembly of cylinder head parts, ensuring the stability of the cylinder head during installation and improving the convenience of installation.

[0040] This disclosure does not limit the specific structure of the limiting structure. In one embodiment provided in this disclosure, such as... Figure 1 and Figure 3 As shown, the limiting component 4 includes multiple limiting blocks 42, which are detachably mounted on the support platform 11. The multiple limiting blocks 42 enclose a limiting region 41. The multiple limiting blocks 42 include two first limiting blocks 421 located in a first direction and one second limiting block 422 located in a second direction, with the first direction perpendicular to the second direction. There can be two fixing members 2, which are respectively spaced apart along the first direction on one side of the two first limiting blocks 421, and the fixing members 2 are located outside the limiting region 41.

[0041] Two first limiting blocks 421, arranged along a first direction, can restrict the position of the cylinder head in the first direction. Simultaneously, a fixing member 2 is provided on the side of the first limiting block 421 away from the limiting area 41, thereby fixing both ends of the cylinder head along the first direction and restricting the cylinder head's position in the vertical direction. A second limiting block 422, arranged along a second direction, can restrict the position of the cylinder head in the second direction. The opposite side of the second limiting block 422 along the second direction is a notch for operator access, facilitating the disassembly and assembly of components on the cylinder head. The mutually perpendicular first and second directions result in a rectangular limiting area 41 formed by the first limiting blocks 421 and 422, facilitating the installation of the support plate 3 and the placement of the cylinder head.

[0042] Meanwhile, since multiple limiting blocks 42 are detachably mounted on the bearing platform 11, and the bearing platform 11 can have multiple mounting holes at different positions, the position of the limiting blocks 42 can be adjusted for different models and specifications of cylinder heads, thereby adjusting the size of the limiting area 41 to adapt to different specifications and models of cylinder heads and improve the applicability of the cylinder head inspection bench 100.

[0043] In another embodiment provided in this disclosure, the limiting component 4 may include a plurality of limiting calipers disposed on the bearing platform 11, wherein the clamping end of the caliper is used to clamp and abut against the side wall of the cylinder head, thereby limiting the position of the cylinder head in the horizontal direction.

[0044] Optionally, such as Figure 3 As shown, the first limiting block 421 and the second limiting block 422 also have chamfers on the side of the limiting area 41, which facilitates the placement of the cylinder head.

[0045] Optionally, the dimension of the first limiting block 421 along the first direction can be 275mm, the dimension of the first limiting block 421 along the second direction can be 35mm, and the thickness of the first limiting block 421 can be 60mm.

[0046] The second limiting block 422 can have a dimension of 170mm along the first direction, a dimension of 40mm along the second direction, and a thickness of 70mm.

[0047] Optionally, such as Figure 3 As shown, the limiting assembly 4 also includes a cylinder head base 43, which is detachably mounted on the support platform 11, and a support plate 3 is detachably mounted on the cylinder head base 43. For different maintenance conditions, either the support plate 3 or the cylinder head base 43 can be used as the support structure for the cylinder head. For example, when repairing and installing cylinder head valve lock plates and springs, the support plate 3 can be used to support the valve head; when disassembling and installing the conical plug of the cylinder head, the cylinder head base 43 can be used to provide sufficient friction for the cylinder head, ensuring its stability during maintenance.

[0048] Optionally, the cylinder head base 43 may have a dimension of 360 mm along the first direction, a dimension of 260 mm along the second direction, a thickness of 12 mm, and the cylinder head base 43 and the plurality of limiting blocks 42 may be made of nylon.

[0049] To facilitate replacement of the load-bearing structure under different circumstances, optionally, such as Figure 2 As shown, the support plate 3 is provided with handles 35 on both sides along the first direction. The support plate 3 can cover the cylinder head base 43, which is set on the support platform 11. When it is necessary to replace the support plate 3 with the cylinder head base 43, the operator can move the support plate 3 by holding the handles 35 to expose the cylinder head base 43.

[0050] Optionally, such as Figure 1 and Figure 3As shown, the main body 1 may also include a support frame 12, one end of which can be fixed to the ground by a fastener 2, and a support platform 11 is disposed at the other end of the support frame 12. The dimension of the support frame 12 along the first direction can be 640mm, the dimension of the support platform 11 along the second direction can be 450mm, and the height of the support platform 11 can be 1000mm.

[0051] Optionally, the dimension of the support platform 11 along the first direction can be 640mm, the dimension of the support platform 11 along the second direction can be 450mm, and the thickness of the support platform 11 can be 8mm.

[0052] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0053] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0054] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
