[0031] Please refer to Figure 1 The engine mount 91 needs to be mounted on a construction machinery (e.g., excavator) chassis 93. The engine mount 91 typically includes four sub-mounts. Each sub-mount has a mounting surface 912 at its top, which is defined by a first hole 914. The engine is mounted on each mounting surface 912 of the engine mount 91. Also mounted on the construction machinery chassis 93 is a main valve mount 95 for mounting a main valve. This main valve mount 95 has a second hole 952. Of course, the number of sub-mounts may also vary.

[0032] The present invention provides a support installation tool, which is used to position the engine support 91 when the engine support 91 is connected to the engineering machinery chassis 93. Figures 2 to 4 The support installation tool of one embodiment includes a tool body 11, a storage rack 13 and a base platform 15. The tool body 11 is used to be placed on the storage rack 13 and the base platform 15. When the support installation tool 10 is not needed, the tool body 11 is placed on the storage rack 13 for easy on-site management; when the support installation tool 10 is needed, the tool body 11 is placed on the tool platform 10 (see Figure 8 ) on the base platform 15. The tool body 11 includes a main frame 112 and an extension arm 114. The extension arm 114 is provided with at least two reference surfaces 1142. The number of the reference surfaces 1142 is determined by the number of the mounting surfaces 912 on the engine support 91.

[0033] In the support installation tool of this embodiment, the engine support can be positioned during installation. At the same time, during positioning, the engine support uses the reference surface 1142 on the tool body as the positioning reference, adopting absolute positioning. Compared with the relative positioning method in the prior art that uses the adjacent counterweight holes on the engine support as the positioning reference, the cumulative positioning error is greatly reduced, the positioning reference is better, and the installation position of the engine support can be ensured to be more accurate to meet production needs.

[0034] In this embodiment, the tool body 11 includes four extension arms 114, each of which is provided with a reference surface 1142. The reference surfaces 1142 are located on the same plane. It is understood that the reference surfaces 1142 do not need to be located on the same plane, as long as they correspond to the required installation positions of the mounting surfaces 912.

[0035] Specifically, the main frame 112 of the tooling body 11 is a frame structure, and the extension arm 114 extends outward from the outside of the main frame 112. More specifically, the main frame 112 is a rectangular frame structure, including two longitudinal beams 1120 and two transverse beams 1121 spaced apart, and the two ends of the two transverse beams 1121 are respectively connected to the two longitudinal beams 1120. Specifically, a lifting ring 1122 is provided on the top of the main frame 112. The lifting ring 1122 can be a screw that is screwed into the main frame 112. When the tooling body 11 is transferred between the storage rack 13 and the base platform 15, the tooling body 11 can be lifted by the lifting ring 1122.

[0036] Specifically, a wear plate 1144 is provided at the bottom of the extension arm 114, and a reference surface 1142 is provided at the bottom of the wear plate 1144. When in use, the reference surface 1142 needs to be close to the mounting surface 912 of the engine mount 91. Providing the reference surface 1142 on the wear plate 1144 can increase its service life.

[0037] Specifically, the extension arm 114 is provided with a positioning pin 1146 extending from one side of the reference surface 1142. Positioning pin 1146 is configured to align with the first hole 914 in the engine mount 91. This positioning pin 1146 allows for rapid positioning of the engine mount 91. More specifically, the extension arm 114 is provided with a removable first sleeve, into which the positioning pin 1146 can be inserted. The first sleeve can be a steel sleeve that fits within the extension arm 114. If the first sleeve becomes worn after prolonged use, it can be replaced with a new one, eliminating the need to replace the entire tooling body 11.

[0038] Specifically, the extension arm 114 is further provided with a reinforcing plate 1148 connected to the main frame 112 , and the reinforcing plate 1148 may be triangular in shape.

[0039] Specifically, the tool body 11 also includes a base 116, and the main frame 112 is fixedly connected to the base 116. The base 116 is used to connect to the base platform 15. Specifically, the base 116 includes a body 1162 and a connecting portion 1164. The body 1162 is connected to the main frame 112. The connecting portion 1164 is provided at one end of the body 1162. The connecting portion 1164 is used to connect to the base platform 15. The connecting portion 1164 is provided with a positioning pin 1166, and the positioning pin 1166 is used to be inserted into the base platform 15. More specifically, a second set is detachably provided on the connecting portion 1164, and the positioning pin 1166 can be inserted into the second set. The second set can be a steel sleeve embedded in the connecting portion 116. When the second set is worn out after long-term use, a new second set can be replaced to avoid replacing the entire tool body 11. Specifically, a pad 1168 is mounted on the positioning pin 1166. When the positioning pin 1166 is connected to the base platform 15, the stepped portion of the positioning pin 1166 abuts against the pad 1168. More specifically, the body 1162 is connected to the center of the main frame 112. The positioning pin 1166 allows for quick positioning of the tool body 11 and the base platform 15, making the operation convenient, fast, and accurate.

[0040] Specifically, the tooling body 11 also includes a detection component 118. A protruding plate 1126 is provided on the main frame 112. Detection component 118 is connected to protruding plate 1126 of the main frame 112. Detection component 118 includes a detection plate 1182 and a detection pin 1184. Detection plate 1182 includes a detection surface 1185 and a detection hole 1186. Detection surface 1185 is configured to engage with the top surface of the main valve support 95 to detect whether the top surface of the main valve support 95 meets the required flatness. Detection pin 1184 is inserted into detection hole 1186 to detect whether the position of the second holes 952 on the main valve support 95 meets the required position. Specifically, the number of detection holes 1186 corresponds to the number of second holes 952. By providing detection component 118, the flatness of the top surface of the main valve support 95 and the position and size of the two second holes 952 on the main valve support 95 can be detected.

[0041] Specifically, the detection component 118 also includes a support plate 1187 and a connecting plate 1188. The support plate 1187 is connected to the detection plate 1182 and the connecting plate 1188, and the connecting plate 1188 is fixedly connected to the protruding plate 1126 of the main frame 112. It can be understood that the connecting plate 1188 can also be directly connected to other positions of the main frame 112. More specifically, the support plate 1187 can be connected to the connecting plate 1188 by a first fastener 1190, and a pin 1192 is inserted into the support plate 1187 and the connecting plate 1188 to position the two. When connecting, the pin 1192 is first inserted into the support plate 1187 and the connecting plate 1188 to position them, and then fixed by the first fastener 1190. Generally, the support plate 1187 and the connecting plate 1188 are not often disassembled. Connecting plate 1188 is connected to main frame 112 via second fasteners 1194. Connecting pins 1195 are inserted into connecting plate 1188 and protruding plate 1126 to position them. To connect, first insert connecting pin 1195 into connecting plate 1188 and protruding plate 1126 to position them, then secure them with second fasteners 1194. Generally, when disassembling detection component 118, it is preferable to disconnect connecting plate 1188 from protruding plate 1126.

[0042] In this embodiment, please refer to Figure 5 The storage rack 13 is a frame structure. It includes a base frame 132, a vertical frame 134, and a connecting rod 136. The vertical frame 134 is perpendicular to the base frame 132, and the two vertical frames 134 are connected to the base frame 132. The ends of the connecting rod 136 are connected to the two vertical frames 134. When stored, the main frame 112 of the tooling body 11 rests on the two vertical frames 134.

[0043] In this embodiment, please refer to Figure 6 The base platform 15 includes a first base 152 and a second base 154 spaced apart. A third set is detachably provided on each of the first base 152 and the second base 154, and the positioning pin 1166 can be inserted into the third set. The third set can be a steel sleeve embedded in the first base 152 and the second base 154. When the third set is worn out after long-term use, it can be replaced with a new one, avoiding the need to replace the base platform 15. In particular, the base platform 15 is fixed to the tooling platform 10, and the disassembly and assembly of the base platform 15 is relatively cumbersome. The flatness and hole position requirements of the base platform 15 are ensured by machining.

[0044] Specifically, the base platform 15 may further include a third base 156 (see Figure 8), the third base 156 is located on the side of the first base 152 away from the second base 154, such that the distance between the first base 152 and the second base 154 is smaller than the distance between the third base 156 and the second base 154. Providing more bases can accommodate machine models of varying sizes, allowing the support installation tool to be shared across multiple models. Furthermore, the working body 11 can be quickly mated with the third assembly on the base platform 15 via the locating pins 1166, minimizing changeover time. In another embodiment, to accommodate a variety of machine models, the third base 156 can be omitted, and at least one of the first base 152 and the second base 154 can be configured to be movable relative to the tooling platform 10. Specifically, a slide can be set on the tooling platform 10, and the slide includes a first slide and a second slide. The first slide is set on the tooling platform 10, and the second slide can move on the first slide along a first direction. At least one of the first base 152 and the second base 154 can be movably set on the second slide along a second direction intersecting (for example, perpendicular) with the first direction.

[0045] In this embodiment, please refer to Figure 7 The support installation tool also includes a clamping member 17, which is used to clamp the engine support 91 and the tooling body 11 together when the mounting surface 912 of the engine support 91 is in contact with the reference surface 1142 and the positioning pin 1146 is inserted into the first hole 914 of the engine support 91, so as to keep the relative position of the engine support 91 and the tooling body 11 unchanged, so as to ensure that the engine support 91 will not move at will after positioning is completed. At this time, the engine support 91 can be connected to the engineering machinery chassis 95 by welding or other methods.

[0046] Specifically, the clamping member 17 includes a C-shaped clip 172 and an abutting portion 174. The abutting portion 174 is connected to one end of the C-shaped clip 172 and is movable toward or away from the other end of the C-shaped clip 172. Specifically, the abutting portion 174 is used to abut the positioning pin 1146, while the other end of the C-shaped clip 172 abuts the opposite side of the mounting surface 912 of the engine mount 91. Specifically, the abutting portion 174 is provided with an external thread, while the C-shaped clip 172 is provided with an internal thread. By twisting the abutting portion 174, its linear movement is achieved.

[0047] Please refer to Figure 8When using the support installation tool of this embodiment to install the engine support 91, the positioning pin 1166 can be inserted into the second kit on the base 116 and the third kit on the base platform 15, so that the tool body 11 is connected to the base platform 15 through the positioning pin 1166; then the mounting surface 912 of the sub-support of the engine support 91 is aligned with the reference surface 1142 of the extension arm 114 of the tool body 11, and the positioning pin 1146 on the extension arm 114 is inserted into the first hole 914 on the sub-support of the engine support 91 (if it cannot be inserted, adjust the position of the sub-support of the engine support 91). At this time, the engine support 91 is positioned, and then the engine support 91 is clamped by the clamping member 17 so that it cannot move at will. Then, the engine support 91 is fixed to the engineering machinery chassis 93 in this position by welding or other methods. In this way, by ensuring the flatness and position of the multiple reference surfaces 1142 on the tooling body 11 of the support installation tool, the position of the engine support 91 during installation can be guaranteed. By inserting the positioning pin 1146 into the first hole 914 of the engine support 91, the size distance between each first hole 914 can be guaranteed, thereby realizing the positioning of the engine support 91 during installation.

[0048] In addition, the support installation tool of this embodiment can also be used to test whether the main valve support 93 is qualified. During testing, the inspection plate 1182 of the inspection component 118 is placed close to the top surface of the main valve support 95. When the bottom surface of the inspection plate 1182 and the top surface of the main valve support 95 can be well aligned, it indicates that the flatness of the main valve support 95 meets the requirements; if they are not well aligned, it indicates that the flatness requirements are not met. The inspection pin 1184 can also be inserted into the inspection hole 1186 of the inspection plate 1182. When the inspection pin 1184 can be inserted into each second hole 952 of the main valve support 95, it indicates that the distance between the second holes 952 meets the requirements; otherwise, it indicates that the distance between the second holes 952 does not meet the requirements. In this way, the flatness and position dimensions of the main valve support 95 are tested.

[0049] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.

[0050] The foregoing description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be readily conceived by a person skilled in the art within the technical scope disclosed herein are intended to be encompassed within the scope of protection of the present invention.
