DETAILED DESCRIPTION

[0031] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0033] Combine the following Figures 1 to 9 A manual handling auxiliary tooling for a die-cast cylinder body according to an embodiment of the utility model is specifically described.

[0034] like Figures 1 to 9 As shown, a manual handling auxiliary tooling for a die-cast cylinder body according to an embodiment of the utility model comprises: an inverted U-shaped main structure 102, a center rod 104, an upper gripping rod 106, a cylinder hole grasping and releasing structure 108, and the like. The inverted U-shaped main structure 102 comprises a cross bar 1022 and two hollow vertical rods 1024 connected to each other. The two center rods 104 are respectively sleeved in the two hollow vertical rods 1024, and the two ends of the upper gripping rod 106 are respectively fixedly connected to the two center rods 104, so that the two center rods 104 are driven to move up and down synchronously by controlling the upper gripping rod 106. Two sets of cylinder hole grasping and releasing structures 108 are respectively movably connected to the bottom of the two hollow vertical rods 1024 and the two center rods 104, and are located at the bottom of both sides of the inverted U-shaped main structure 102. In other words, a center rod 104 is set inside a center vertical rod of the inverted U-shaped main structure 102, and a set of cylinder hole grabbing and releasing structures 108 are movably connected to the center vertical rod and the bottom of the center rod 104. The cylinder hole grabbing and releasing structures 108 include: two sets of mirror-symmetrical connecting plates 1082 and pressure rods 1084, one end of the connecting plate 1082 is rotatably connected to the bottom end of the hollow vertical rod 1024, the other end of the connecting plate 1082 is rotatably connected to the pressure rod 1084, and the pressure rod 1084 is rotatably connected to the bottom end of the center rod 104. Through the simple structure of the tooling, the linear movement of the center rod 104 is cleverly converted into the action of grabbing and releasing, and the pressure rod 1084 is used to clamp and release the position of the crankshaft hole of the aluminum alloy cylinder block, so as to realize the overall transportation of the die-cast cylinder block.

[0035] Furthermore, if Figures 1 to 3 as well as Figures 7 to 9As shown, the pressure rod 1084 includes a connecting portion 1084-1 and a gripping portion 1084-2. The connecting portion 1084-1 is movably connected to the connecting plate 1082 and the center rod 104, respectively. The gripping portion 1084-2 is L-shaped, and the end close to the connecting portion 1084-1 is higher, and the portion of the higher portion in contact with the cylinder crankshaft hole is a curved surface. Therefore, not only can the position of the cylinder crankshaft hole be firmly clamped, but also the die-cast cylinder body is not easily damaged.

[0036] Furthermore, if Figures 1 to 4 As shown, and Figure 6 As shown, two connecting protrusions 1024-1 are symmetrically arranged at the bottom of the hollow vertical rod 1024, and connecting protrusions 1024-1 are provided with connecting through holes 110; the connecting plate 1082 is in the shape of a long strip, and connecting through holes 110 are respectively provided at both ends; bolts 112 pass through the connecting through hole 110 at one end of the connecting plate 1082 and the connecting through hole 110 on the connecting protrusion 1024-1, and the two are movably connected. Thus, a rotating action can be performed, and the connecting plate 1082 can rotate relative to the hollow vertical rod 1024.

[0037] Furthermore, if Figures 1 to 3 as well as Figure 7 As shown, two connecting through holes 110 are arranged at intervals on the connecting portion 1084-1 of the pressure rod 1084, wherein the connecting through hole 110 near the gripping and releasing portion 1084-2 is movably connected to the connecting through hole 110 at the other end of the connecting plate 1082 by a bolt 112. Thus, a rotation action can be performed, and the connecting plate 1082 and the pressure rod 1084 can rotate relative to each other.

[0038] Furthermore, if Figures 1 to 3 as well as Figure 5 As shown, the bottom end of the center rod 104 is provided with a connecting through hole 110, which is movably connected to the connecting through hole 110 on the end side of the connecting portion 1084-1 of the pressure rod 1084 through a bolt 112; the two mirror-symmetrical pressure rods 1084 are connected to the same position of the center rod 104. Therefore, the center rod 104 can be rotated, and the up and down movement of the center rod 104 drives the pressure rod 1084 to move, so as to achieve the clamping and loosening of the position of the cylinder crankshaft hole.

[0039] Furthermore, if Figures 1 to 4 As shown, the die-casting cylinder manual handling auxiliary tooling also includes: a lower grip rod 114, which is fixedly connected to the center position of the cross bar 1022. Thus, it is more convenient to operate.

[0040] Furthermore, the lower grip bar 114 is welded to the cross bar 1022, and the upper grip bar 106 is welded to the two center bars 104. Thus, the reliability is further improved.

[0041] In addition, the power mechanism can be connected through the upper gripping rod 106 and the lower gripping rod 114 to increase electrical action, thereby realizing automatic grasping, placing and transporting of the die-casting cylinder body.

[0042] The working process of the manual handling auxiliary tooling for a die-casting cylinder body proposed in the utility model is as follows:

[0043] Insert the two hollow vertical rods 1024 of the manual handling auxiliary tooling of the die-casting cylinder body into the first and fourth cylinder holes of the die-casting cylinder body. The operator grabs the upper grip rod 106 and the lower grip rod 114 by hand to shorten the distance between them. The center rod 104 moves downward. Through the mutual rotation of the pressure rod 1084 and the bolt 112, the left and right pressure plates expand outward to clamp the crankshaft hole position of the die-casting cylinder body. Figure 8 As shown, the entire die-cast cylinder body can be lifted up with the help of this tool.

[0044] After the die-casting cylinder body is moved to the designated position, the operator lifts the upper grip rod 106. At this time, the distance between the upper grip rod 106 and the lower grip rod 114 increases, and the center rod 104 moves upward. The left and right pressure rods 1084 are retracted inwardly through the mutual rotation of the pressure rod 1084 and the bolt 112, and the crankshaft hole position of the die-casting cylinder body is loosened. Fig. 9 As shown, the entire tooling can now be pulled out of the cylinder bore.
