[0024] The specific embodiments described hereinbefore are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0025] In the present application, the orientation words such as "up", "down", "in" and "out" contained in the terms only represent the orientation of the terms in the normal use state or the common name understood by the person skilled in the art, and should not be regarded as the limitation of the terms.

[0026] As shown in Figures 1-4 An engine shell clamping tool, comprising: a workbench 1, a pressing unit for pressing on the top of the shell assembled on the workbench 1 through a first mounting frame 2, a horizontal support plate 3 and a horizontal moving mechanism 4 assembled on the workbench 1 for driving the support plate 3 to move to the position directly below the pressing unit.

[0027] The support plate 3 is provided with a plurality of positioning blocks 5 arranged at the edge interval of the support plate 3, and a plurality of mounting holes 6 are recessed on the support plate 3, and at least one mounting hole 6 is provided with a vertical positioning column 7 matched with the shell.

[0028] In the above technical solution, the shell of the engine to be processed is placed on the support plate 3, the shell is placed between the plurality of positioning blocks 5, and the positioning column 7 is also inserted into the hole or groove on the shell. The plurality of positioning blocks 5 can facilitate the preliminary positioning of the shell, so that the operator can place the shell between the plurality of positioning blocks 5, and the positioning column 7 is inserted into the shell, which can further improve the accuracy of the positioning of the shell.

[0029] After the shell is positioned on the support plate 3, the horizontal moving mechanism 4 pushes the support plate 3 towards the pressing unit, and the shell is pushed to the position directly below the pressing unit. The pressing unit is started to press and hold the shell, at this time the shell is clamped and fixed, and the next step of processing can be carried out, for example, the steel ball is plugged into the corresponding hole position of the shell.

[0030] The positioning column 7 can be assembled on the mounting hole 6 at different positions according to different engine shell types, and the position of the positioning block 5 can be adjusted or the obstructed positioning block 5 can be disassembled, so that the tool is suitable for different types of engine shells.

[0031] The horizontal moving mechanism 4 is a mature technology, and therefore the specific structure is not described and introduced herein. A lead screw slide or a third driving push rod can be used for driving.

[0032] In a preferred embodiment of the application, a plurality of parallel waist-shaped through grooves are arranged on the top of the positioning block 5, the upper end of each waist-shaped through groove is provided with a waist-shaped stepped groove 8, and an installation bolt 9 is arranged in each waist-shaped through groove and is threadedly connected with the support plate 3 and has a head capable of abutting against the bottom wall of the waist-shaped stepped groove 8.

[0033] In the above technical solution, the positioning block 5 can slide by loosening the installation bolt 9, so as to adjust the position of the positioning block 5, and then the positioning block 5 is fixed by tightening the installation bolt 9.

[0034] In a preferred embodiment of the application, the workbench 1 is provided with a positioning member 11 located in the forward direction of the horizontal moving mechanism 4 and capable of contacting the outer wall of the shell through the second mounting frame 10.

[0035] In the above technical solution, when the horizontal moving mechanism 4 moves the support plate 3 to be directly below the pressing unit, the outer wall of the shell will contact the positioning member 11, and the moving end of the horizontal moving mechanism 4 stops moving. At this time, the shell is just located directly below the pressing unit, and the positioning member 11 is beneficial to the positioning of the shell.

[0036] In a preferred embodiment of the application, the workbench 1 is further provided with a pair of auxiliary positioning mechanisms arranged in a symmetrical state with respect to the support plate 3 and located on the side of the first mounting frame 2 away from the positioning member 11.

When the steel ball, the bowl-shaped cover or the waterway port is pressed and assembled on the shell, the side wall of the shell will be subjected to a transverse thrust. Therefore, the shell is clamped by the positioning member 11 and the pressing arm 14, so as to share the transverse thrust of the shell when the steel ball is inserted, and the clamping stability of the shell is improved.

[0039] In a preferred embodiment of the application, the pressing arm 14 is provided with a notch part matching the corner of the shell.

[0040] In a preferred embodiment of the application, the pressing unit comprises a vertical second driving push rod 15 assembled on the first mounting frame 2 and a pressing piece 16 assembled on the moving end of the second driving push rod 15.

[0041] In the above technical solution, the second driving push rod 15 drives the pressing piece 16 to move vertically downward to be pressed on the top of the shell to cooperate with the supporting plate 3 to clamp the shell from the vertical direction.

[0042] The preferred embodiments of the application are described in detail above with reference to the drawings, but the application is not limited to the specific details in the above embodiments, and various simple modifications can be made to the technical solutions of the application within the technical concept of the application, and these simple modifications all belong to the protection scope of the application.
