Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of diesel engines, and more particularly to a hinge assembly and a hinge method. BACKGROUND

[0002] The diesel engine foot and the common base are important parts of the diesel engine power module, and are core parts for ensuring that the vibration noise and impact resistance of the device meet the technical requirements. In particular, the hinge bolt assembly between the foot and the common base is a guarantee that the diesel engine does not move relative to the common base when the diesel engine is subjected to instantaneous impact and a reference for reassembling the diesel engine after overhaul.

[0003] When the diesel engine power module device is complete, the diesel engine is placed on the common base through the diesel engine foot, and is connected together through a plurality of bolts. At the same time, in order to ensure the resistance to instantaneous impact and positioning after disassembly, the diesel engine foot and the common base are connected through two hinge holes and hinge hole bolts and nuts. The on-site hinge hole machining of the diesel engine foot and the common base hinge hole is a key and difficult process in the diesel engine power module completion process. Due to the space limitation of the diesel engine power module and the functional requirements of the hinge hole, mechanical machining of the hinge hole is difficult, and only manual hinge hole machining can be used.

[0004] The existing diesel engine foot and common base hinge process is as follows: the diesel engine is lifted and placed on the common base, the bolts are inserted into the bolt holes on both sides of the diesel engine foot before the diesel engine is lowered, then the diesel engine is lowered so that all the bolts on both sides of the foot fall into the corresponding holes of the common base, and all the bolts can be easily pulled up and down, and then the diesel engine is placed on the common base. After the diesel engine is seated, all the bolts are tightened to the torque (except for the two holes for installing the hinge bolts), the coaxiality of the upper and lower hinge holes is determined, and the hole is expanded and hinged by hand.

[0005] 1. Because the hinge hole is not accurately positioned when the diesel engine is seated, the coaxiality of the upper and lower holes is poor, there is a significant step, and due to the space limitation, magnetic drilling cannot be used for hole expansion, only different diameter reamers can be used, and more than 20 reamers are often needed to eliminate the hole coaxiality to ensure the hole coaxiality;

[0006] 2. It is not possible to ensure the perpendicularity of the hinge hole and the bolt mounting plane: the straight reamer used in the hinge process has no positioning and limiting function during the hole reaming process, and only slow feeding can be ensured to ensure the consistency of the upper and lower holes during the hole reaming process; due to the space limitation, only one side of the wrench can be used to rotate, and the reamer cannot be guaranteed to be perpendicular to the hinge hole and the bolt mounting plane.

[0007] Therefore, it is necessary to provide a hinge assembly and a hinge method to at least partially solve the above problems. SUMMARY

[0008] A series of simplified concepts are introduced in the summary section, which will be further described in detail in the specific embodiment section. The summary section of the present application does not mean to attempt to limit the key features and essential technical features of the claimed technical solutions, nor to attempt to determine the protection scope of the claimed technical solutions.

[0009] To at least partially solve the above problems, the first aspect of the present application provides a hinge assembly for hinge boring of a diesel engine foot and a common base, the hinge assembly comprising:

[0016] According to the reaming assembly of the first aspect of this application, when the operator is making reaming holes on the diesel engine and the common base, the operator installs a seating guide mechanism, then lowers the diesel engine so that the pre-drilled holes for reaming on the diesel engine mount pass through the tapered pin until the diesel engine is lowered onto the common base. At this time, the bottom surface of the diesel engine mount mates with the top surface of the common base, and the pre-drilled holes for reaming on the diesel engine mount and the common base are coaxial. Then, the operator installs a reaming mechanism, tightens the rotary return member, and rotates the reamer, repeating the action to ream the diesel engine mount and the common base. Compared with the existing reaming methods for diesel engines and common bases, this application uses a seating guide mechanism, which ensures that the pre-drilled holes for reaming on the diesel engine mount are accurately aligned with the pre-drilled holes for reaming on the common base under the guidance of the tapered pin, thereby improving the positioning accuracy of the reaming holes. In addition, the operator uses a rotary return member in conjunction with the reamer to make the holes, ensuring that the perpendicularity of the reamer is maintained during reaming. Therefore, the reaming assembly of this application has the advantages of accurate positioning, high processing accuracy, and low operation difficulty.

[0068] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0069] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.

[0070] The hinge assembly according to this application is used for hinge mounting between the diesel engine and the common base 101. (Refer to...)Figure 1 In this embodiment, a diesel engine foot 100 is provided at the bottom of the diesel engine, and an upper mounting beam 102 and a lower mounting beam 103 are provided on the common base 101. The upper mounting beam 102 is positioned above the lower mounting beam 103, and the top surface of the upper mounting beam 102 is used to mate with the bottom surface of the diesel engine foot 100. Before the diesel engine and the common base 101 are hinged, both the diesel engine foot 100 and the upper mounting beam 102 are provided with pre-drilled hinge holes.

[0071] Figures 2 to 6 A hinge assembly according to this application is shown for hinge holes in a diesel engine mount 100 and a common base 101. The hinge assembly includes a seating guide mechanism 110 and a hinge hole mechanism 120. The seating guide mechanism 110 includes a positioning member 111 and a tapered pin 112. The positioning member 111 is disposed on the common base 101 during use and is used to pass through the hinge pre-drilled hole in the common base 101. The tapered pin 112 passes through the positioning member 111 and is used to pass through the hinge pre-drilled hole in the diesel engine mount 100 during seating.

[0072] The reaming mechanism 120 includes a reamer 121 and a rotary return member. The reamer 121 is used to pass through the pre-drilled reaming hole in the diesel engine mount 100 and the pre-drilled reaming hole in the common base 101. The reamer 121 is provided with a threaded portion 125 (the thread of the threaded portion 125 is not shown), which protrudes below the pre-drilled reaming hole in the common base 101. The rotary return member is sleeved onto the reamer 121 and is located below the pre-drilled reaming hole in the common base 101 during use, and the rotary return member is threadedly connected to the reamer 121 via the threaded portion 125.

[0073] According to the reaming assembly of this application, when the operator is making reaming holes in the diesel engine and the common base 101, the operator installs the seating guide mechanism 110, and then lowers the diesel engine so that the reaming pre-drilled hole of the diesel engine mount 100 passes through the tapered pin 112 until the diesel engine is lowered onto the common base 101. At this time, the bottom surface of the diesel engine mount 100 mates with the top surface of the common base 101, and the reaming pre-drilled hole of the diesel engine mount 100 is coaxial with the reaming pre-drilled hole of the common base 101. Then the operator installs the reaming mechanism 120, tightens the rotating return member, and then rotates the reamer 121. The operation is repeated to make reaming holes in the diesel engine mount 100 and the common base 101. Compared to existing methods for reaming diesel engines and common base 101, this application employs a seating guide mechanism 110, which ensures that the pre-drilled reaming hole of the diesel engine mount 100 is accurately aligned with the pre-drilled reaming hole of the common base 101 under the guidance of the tapered pin 112, thereby improving the positioning accuracy of the reaming hole. Furthermore, the operator uses a rotating return assembly in conjunction with a reamer 121 to ream the hole, maintaining the perpendicularity of the reamer 121 during reaming. Therefore, the reaming assembly of this application offers precise positioning, high machining accuracy, and low operational difficulty.

[0074] In detail, refer to Figure 2 The positioning component 111 includes a positioning sleeve 113 and a pad 114, the pad 114 being cylindrical. (See reference...) Figure 3 The positioning sleeve 113 includes a first tube 115 and a second tube 116, with the inner diameters of the first tube 115 and the second tube 116 being the same. The outer diameter of the first tube 115 is the same as the diameter of the pre-drilled hinge hole in the common base 101. The outer wall of the second tube 116 protrudes beyond the outer wall of the first tube 115. In use, the positioning sleeve 113 is inserted into the pre-drilled hinge hole of the upper mounting beam 102 of the common base 101 through the first tube 115. Then, a pad 114 is positioned below the positioning sleeve 113 in the vertical direction Z, such that the bottom surface of the pad 114 abuts against the top surface of the lower mounting beam 103, and the top surface of the pad 114 abuts against the bottom end of the second tube 116, thereby securing the positioning sleeve 113 to the common base 101.

[0075] After the positioning sleeve 113 is installed, the workers install the tapered pin 112. (Refer to...) Figure 3 The tapered pin 112 includes a tapered portion 117 and a mating portion 118. The diameter of the tapered portion 117 gradually decreases in the vertical Z-direction upwards, and the maximum diameter of the tapered portion 117 is consistent with the outer diameter of the first tube 115. (Refer to...) Figure 2During the installation of the tapered pin 112, the worker inserts the mating part 118 into the first tube 115 through the pre-drilled hole of the upper mounting beam 102, with the tapered part 117 abutting against the top of the first tube 115. When the diesel engine is lowered, the pre-drilled hole of the diesel engine mount 100, guided by the tapered surface of the tapered part 117, gradually moves horizontally to a position coaxial with the pre-drilled hole of the common base 101, until the diesel engine mount 100 mates with the common base 101, completing the precise positioning of the diesel engine.

[0076] After the diesel engine is seated, the workers remove the seat guide mechanism 110 and then install the reaming mechanism 120.

[0077] Reference Figure 4 When installing the reaming mechanism 120, the operator passes the reamer 121 through the pre-drilled reaming hole of the diesel engine foot 100 and the pre-drilled reaming hole of the upper mounting beam 102 in sequence until the bottom end of the reamer 121 protrudes from the bottom surface of the upper mounting beam 102. Then the operator installs the rotating tightening member to the bottom end of the reamer 121.

[0078] In detail, refer to Figure 5 The reamer 121 includes a rotating block 123, cutting edges 124, and a threaded portion 125. The rotating block 123 is rectangular, with a square cross-section perpendicular to the axis of the reamer 121, to mate with tools such as a wrench 122. The reamer 121 includes multiple cutting edges 124, which are evenly arranged around the axis of the reamer 121. The threaded portion 125 is located at the bottom end of the reamer 121, and after the reamer 121 is installed, the threaded portion 125 is at least partially located below the bottom surface of the upper mounting beam 102.

[0079] Reference Figure 4 The rotary tightening component includes a bearing 126 and a nut 127. The bearing 126 can be a roller bearing, and the nut 127 can be a hexagonal nut. When installing the rotary tightening component, the operator places the bearing 126 onto the bottom end of the reamer 121 (i.e., below the upper mounting beam 102), and then places the nut 127 onto the reamer 121. The nut 127 has internal threads that connect with the threaded portion 125. When the nut 127 is tightened, the top surface of the nut 127 presses against the bearing 126, and the top surface of the bearing 126 presses against the bottom surface of the upper mounting beam 102, causing the reamer 121 to experience a downward pulling force. By rotating the reamer 121 and simultaneously rotating the nut 127, the operator can ream the diesel engine mount 100 and the common base 101.

[0080] Reference Figure 6When the operator rotates the nut 127, and the bearing 126 still cannot engage with the bottom surface of the upper mounting beam 102, the cutting edge 124 of the reamer 121 is not fully protruding from the bottom surface of the upper mounting beam 102, and the reaming is insufficient. At this time, the reaming mechanism 120 also includes a guide sleeve 128. The operator removes the nut 127 and the bearing 126, and places the guide sleeve 128 onto the reamer 121. Then, the bearing 126 and the nut 127 are installed in sequence. When the operator tightens the nut 127, one end of the guide sleeve 128 abuts against the bottom surface of the upper mounting beam 102, and the other end abuts against the top surface of the bearing 126. At this time, the nut 127 still exerts a pulling force on the reamer 121, and the operator can still rotate the reamer 121 and rotate the nut 127 in conjunction until the reaming is completed.

[0081] In summary, this application provides a hinge assembly, and this application also provides a hinge method, including:

[0082] S1: Clean the bottom surface of the diesel engine mount 100, the top and bottom surfaces of the upper mounting beam 102 of the common base 101, and the top surface of the lower mounting beam 103;

[0083] S2: Install seating guide mechanism 110;

[0084] S3: Repeat S2, and install the seating guide mechanism 110 at another hinge position of the common base 101;

[0085] S4: Lift the diesel engine and lower it gradually. During this process, adjust its position so that the tapered pin 112 is inserted into the pre-made hole of the diesel engine foot 100 in the vertical direction Z until the diesel engine foot 100 is engaged with the common base 101.

[0086] S5: Remove the seating guide mechanism 110;

[0087] S6: Install the bolts between the diesel engine mount 100 and the common base 101, excluding the hinge position, and tighten each bolt to the corresponding torque requirement;

[0088] S7: Clean the diesel engine mount 100 and the common base 101 again, and confirm the coaxiality of the pre-drilled hole for the common base 101 and the pre-drilled hole for the diesel engine mount 100.

[0089] S8: Install reamer 121 and rotating return mechanism;

[0090] S9: Rotate the reamer 121 to a certain angle and tighten the rotating return member. Repeat the above actions until the rotating return member is separated from the common base 101.

[0091] S10: Remove the rotating return member, insert the guide sleeve 128, and then repeat S9 until the reamer 121 is fully protruding from the common base 101;

[0092] S11: Remove the hinge mechanism 120, repeat S8 to S10, and complete the hinge matching at another hinge position;

[0093] S12: After the hinge is fitted, install the hinge fitting bolts.

[0094] According to the hinge fitting method of this application, the hinge fitting positioning is accurate, the coaxiality of the hinge fitting hole is high, and the operation is easy.

[0095] Optionally, in step S2, the positioning sleeve 113 is installed into the pre-drilled hinge hole of the common base 101. Then, a pad 114 is placed on the common base 101 and abuts against the underside of the positioning sleeve 113 to support it. Lubricant is then applied to the tapered pin 112, and the tapered pin 112 is inserted into the positioning sleeve 113 through the pre-drilled hinge hole of the common base 101. With the pad 114 and positioning sleeve 113 in place, the tapered pin 112 passes through the pre-drilled hinge hole of the common base 101 and is supported by the positioning sleeve 113. This allows the tapered surface of the tapered pin 112 to exert a horizontal force on the diesel engine mount 100 when the diesel engine is seated, thereby positioning the diesel engine. Compared to bolt positioning, this method offers more precise positioning.

[0096] Optionally, in step S5, the pad 114 is first removed, then the tapered pin 112 is pulled out, and finally the positioning sleeve 113 is removed from the pre-drilled hinge hole of the common base 101. The pad 114 can be removed by tapping it for easy disassembly. Then, the tapered pin 112 is pulled out first, and then the positioning sleeve 113 is tapped out of the pre-drilled hinge hole of the common base 101 using a tool, which helps prevent damage to the tapered pin 112 during tapping.

[0097] Optionally, in S7, coaxiality can be confirmed by observing the size of the upper and lower pre-drilled holes.

[0098] Optionally, in S8, the reamer 121 is passed through the pre-drilled holes of the diesel engine mount 100 and the common base 101 in sequence until the cutting edge 124 of the reamer 121 contacts the top surface of the diesel engine mount 100. Then, the bearing 126 and the nut 127 are sequentially fitted to the bottom end of the reamer 121, and the nut 127 is tightened so that the top surface of the bearing 126 fits against the common base 101, thereby causing the reamer 121 to receive a downward pulling force.

[0099] In S9, after rotating the reamer 121 to a certain angle, tighten the nut 127, so that the reamer 121 is continuously subjected to a downward pull, thereby allowing the cutting edge 124 of the reamer 121 to cut the inner wall of the pre-reamed hole. When the operator rotates the nut 127 and the bearing 126 is still separated from the bottom surface of the upper mounting beam 102, proceed to S10 until the reamer 121 completes the reaming of the pre-reamed holes of the diesel engine mount 100 and the common base 101.

[0100] Furthermore, the operator should rotate the reamer 121 by no more than 60° each time using the wrench 122; the rotation angle can be selected as 30° or 45°. This smaller rotation angle setting for the reamer 121 ensures sufficient downward pulling force during rotation, guaranteeing the uniformity of the reamed hole and improving the accuracy of the reaming process.
