[0041] Through the cooperation between the adapter component and the tensioning component, the positioning and locking of the valve body casting test block is completed according to the thread tightening method to avoid looseness.

[0042] The driving mechanism 5 includes a bearing assembly, an extension assembly, a rotating assembly and a pushing assembly. The bearing assembly is arranged on the back of the tooling frame 1, the extension assembly is arranged inside the bearing assembly, the rotating assembly is arranged on the top of the bearing assembly, and the pushing assembly is arranged on the top of the bearing assembly.

[0043] Through the cooperation between the bearing component, the extension component, the rotating component and the pushing component, the power output operation is realized, and the output position is adjusted, so that the output is directly realized to the fastening mechanism 4 according to the rotation method, so as to complete the fastening operation. After fastening, it can be checked again by a manual torque wrench whether it is fastened. If it is fastened, the operation can be carried out directly. If the fastening is not up to standard, manual auxiliary fastening can be performed.

[0044] Preferred;

[0045] like Figure 2 As shown, the connecting assembly 2 includes a partition 21, which is fixedly installed on the inner wall of the tooling frame 1 at intervals. The top and bottom of the back of the tooling frame 1 are evenly spaced with first connecting holes 22, and the middle of the back of the tooling frame 1 is evenly spaced with second connecting holes 23, which are convenient for spacing during positioning and assist the following components in positioning the valve body casting test block.

[0046] further;

[0047] like Figure 3 As shown, the support assembly includes a cross bar 31, which is fixedly mounted on the inner wall of the tooling frame 1. The outer side of the cross bar 31 is slidably connected to a limit seat 32. An adapter groove 34 is provided on the surface of the limit seat 32 to facilitate sliding support operations and provide back support for the inserted test block.

[0048] like Figure 3 As shown, the installation assembly includes a first bolt 35, which is inserted into the first connecting hole 22. A third connecting hole 33 is provided on the back of the limit seat 32. One end of the first bolt 35 is threadedly connected to the limit seat 32 through the third connecting hole 33, and the locking operation is achieved by bolting.

[0049] It is worth explaining;

[0050] like Figure 4 As shown, the adapter assembly includes a fastening seat 42, which is arranged inside the fixture frame 1. The surface of the fastening seat 42 is provided with a connecting groove 43, which can facilitate the insertion of the adapter valve body casting test block.

The valve body casting test block is tightly positioned by threaded fastening to ensure stability during cutting.

[0052] When operating, pre-tighten and install the limit seat 32, slide the limit seat 32 on the surface of the cross bar 31, and slide to the preset position. At this time, take out the first bolt 35 and pass it through the first connecting hole 22 to penetrate the tooling frame 1. At the same time, the thread extends into the third connecting hole 33 opened on the back of the limit seat 32. At this time, the limit seat 32 is fixed. There are several limit seats 32, and two groups are symmetrically arranged up and down. After operating the upper limit seat 32, the lower limit seat 32 can be operated according to the above operation;

[0053] When the above-mentioned components have completed the operation, the valve body casting test block is directly taken out, and the fastening seat 42 is penetrated from the top to the bottom through the connecting groove 43, and is located inside the connecting groove 43. Based on the above-mentioned number, the required number of valve body casting test blocks can be inserted in sequence, and the cutting operation can be carried out synchronously after several groups of valve body casting test blocks are fixed. Subsequently, the fastening seat 42 and the second bolt 41 can be threadedly connected by rotating the second bolt 41 through the external torque wrench and the following driving mechanism 5, and the position of the fastening seat 42 is separated and limited, so it will move backward on the surface when the second bolt 41 is rotated until the inner side wall of the connecting groove 43 is pressed against the outer surface of the valve body casting test block for positioning.

[0054] After the above operations are completed, the valve body casting test block can be cut.

[0055] Going a step further;

[0056] like Figure 5 As shown, the bearing assembly includes an outer support frame 51, which is fixedly mounted on the back of the tooling frame 1. A cross plate 55 is placed on the top of the outer support frame 51 to support the components on the top and enable horizontal sliding when pushed.

[0057] like Figure 8 As shown, the extension assembly includes a fixed plate 512 fixedly installed at both ends of the bottom of the horizontal plate 55, a telescopic rod 513 fixedly installed on the back of the fixed plate 512, and one end of the telescopic rod 513 is fixed to the outer support frame 51, which can support the above-mentioned components and realize the extension operation during movement.

[0058] like Figure 6As shown, the rotating assembly includes a mounting plate 56, which is fixedly mounted on the top of the transverse plate 55. A shaft 57 is rotatably connected to the surface of the mounting plate 56. An external hexagonal joint 58 is fixedly mounted on one end of the shaft 57. A pulley 59 is fixedly mounted on the outer side of the other end of the shaft 57. A belt 510 is sleeved on the outer side of the pulley 59. A motor 511 is fixedly mounted on the top of the transverse plate 55. The output shaft of the motor 511 is key-connected to the other end of the shaft 57. The shaft 57 corresponding to the motor 511 is rotated according to the power output, and the output of the rotational force is completed through the transmission between a plurality of groups of pulleys 59 and the belt 510. The second bolt 41 can be tightened and loosened in a mechanized manner.

[0059] like Figure 5 As shown, the pushing assembly includes an electric push rod 52, which is fixedly mounted on the top of a horizontal plate 55. A connecting plate 53 is fixedly mounted on the output end of the electric push rod 52. A protective cover 54 is fixedly mounted on the surface of the connecting plate 53. The protective cover 54 is bolted to the top of the horizontal plate 55. The position of the adapter during rotation can be adjusted according to the push-pull effect, thereby achieving full adaptation and disengagement operation after tightening.

[0060] As mentioned above, in normal operation, there is no need to tighten with a manual hexagonal torque wrench. At this time, the electric push rod 52 first drives the protective cover 54 and the cross plate 55 to slide on the top of the outer support frame 51 by pushing the connecting plate 53 until the hexagonal joint 58 is driven to move and the hexagonal joint 58 can be inserted into the adapter end of the second bolt 41. At this time, it is necessary to start the motor 511, and use the motor 511 to drive the corresponding connected shaft rod 57 to rotate, and then according to the rotation of several groups of pulleys 59 and belts 510, several groups of shaft rods 57 are rotated, thereby completing the transmission of rotational force, ensuring that several groups of hexagonal joints 58 are synchronously driven to rotate, and then adapted to be inserted into the adapter end of the second bolt 41, and tightening and loosening work is performed according to rotation;

[0061] Tightening is done by rotating clockwise, while loosening is done by rotating counterclockwise.

[0062] After the above operation, the second bolt 41 can be checked to see if it is tightened according to the actual situation. For example, the second bolt 41 can be directly adapted and rotated by a manual hexagonal torque wrench to see if it is tightened after the adapted rotation.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
