DETAILED DESCRIPTION

[0033] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] A control assembly assembly device provided by the present invention comprises: an assembly platform 1, a control rod support plate 2, a support plate connecting shaft 3, a punching guide plate 4, a connecting handle positioning tool 5 and a punching device 6, wherein a plurality of control rod support plates 2 and a punching guide plate 4 are installed on the assembly platform 1, the support plate connecting shaft 3 passes through the control rod support plate 2 and the punching guide plate 4, the connecting handle positioning tool 5 is installed on the outer side of the punching guide plate 4 on the assembly platform 1, and the punching device 6 is arranged on the side of the assembly platform 1.

[0035] The assembly platform 1 supports other tooling during the control component assembly process, and after the control component assembly is completed, it is combined with the electric cylinder 7 to perform the component flipping and lifting function.

[0036] like Figure 2 As shown, each control rod support plate 2 includes a first rotatable support plate 8, a first support frame 9 and a first rotating wheel 10, which support the control rods during the control assembly assembly process and assist in drilling the control rods during the control rod drilling process; wherein, the bottom of the first support frame 9 is a mounting seat, the mounting seat is a plate-like structure with outer protrusions at both ends, and can be clamped on the assembly platform 1, the middle upper part of the mounting seat is two support plates, and a first rotating wheel 10 is respectively installed on the top and bottom of the two support plates, and there are four first rotating wheels 10 in total, and the disc-shaped first rotatable support plate 8 is clamped between the four first rotating wheels 10, and the middle of the first rotatable support plate 8 is a square hole structure, and the support plate connecting shaft 3 can pass through the square hole. The first rotatable support plate 8 is evenly distributed with a plurality of circular holes. In the embodiment of the present invention, the first rotatable support plate 7 has two circles of circular holes, the number of the inner circle is 8, and the number of the outer circle is 16, totaling 24.

[0037] like Figure 3As shown, the punching guide disk 4 includes a second rotatable support disk 21, a second support frame 19, a second rotating wheel 20, and a punching positioning tool 11, which assists the punching device in guiding and positioning during the control rod punching process; wherein, the bottom of the second support frame 19 is a mounting seat, and the mounting seat is a plate-like structure with external protrusions at both ends, which can be clamped on the assembly platform 1, and the middle upper part of the mounting seat is two support plates, and a second rotating wheel 20 is respectively installed at the top and bottom of the two support plates. There are four second rotating wheels 20 in total, and the disc-shaped second rotatable support disk 21 is clamped between the four second rotating wheels 20. The middle of the first rotatable support disk 8 is a square hole structure, and the support disk connecting shaft 3 can pass through the square hole. The second rotatable support disk 21 is evenly distributed with a plurality of circular holes. In the embodiment of the present invention, the second rotatable support disk 21 has two circles of circular holes, the number of the inner circle is 8, and the number of the outer circle is 16, totaling 24. A punching positioning tool 11 is installed on each circular hole on the second rotatable support disk 21, such as Figure 5 As shown, the bottom surface of the main structure of the punching and positioning tool 11 is designed with an inverted V-shaped groove to assist in positioning the relevant rods; a special guide hole for the drill bit is set on the main structure to assist in determining the drilling points of the relevant rods. The 24 punching and positioning tool 11 has eight different orientations to meet the drilling requirements of the inner and outer ring control rods.

[0038] Among them, the first rotatable support plate 8 of the control rod support plate 2 is made of polyethylene material: 1) when supporting the control rod, it is possible to avoid adverse effects on the surface quality of the control rod; 2) the lighter weight of the polyethylene material also means smaller torsional force during rotation, reducing the burden on the operator when rotating the component; 3) the lighter weight of the polyethylene material also means smaller inertia during rotation, which reduces the torsion of the control rod to a certain extent and reduces the degree of torsion of the control rod.

[0039] The second rotatable support plate 21 of the punching guide plate 4 is made of stainless steel: 1) the punching guide plate needs to be slotted to realize the positioning of the punching positioning tool 11, and the use of metal material can ensure the accuracy of the tool positioning to a greater extent; 2) when the overall rotation control assembly is used, the control rod support plate 2 rotates with the support plate connecting shaft 3, and the punching guide plate 4 drives the connecting handle to rotate, which requires the punching guide plate 4 to have stronger mechanical properties than the control rod support plate 2.

[0040] like Figure 8 As shown, the support plate connecting shaft 3 includes a square shaft locking sleeve 17 and a square connecting shaft 18. The square shaft locking sleeve 17 is mounted on the square connecting shaft 18 to assist the control rod support plate in rotating. The support plate connecting shaft 3 adopts a square shaft structure, and the square shaft locking sleeve 17 simultaneously connects the rotatable support plate 8 and the square connecting shaft 18 to avoid the asynchronous rotation of the multi-layer control rod support plate due to slipping, thereby causing the consequences such as the torsion of the control rod.

[0041] The operator manually operates the connecting shaft 3 to rotate, and the connecting shaft 3 drives the first rotatable supporting disk 8 to rotate.

[0042] like Figure 7 As shown, the connection handle positioning tool 5 includes a three-jaw chuck 15, a three-jaw chuck base 12, a three-jaw chuck support 13, a positioning tool 14 and a connection handle protective cover 16, which realize the positioning and support of the connection handle; wherein, the positioning tool 14 is a plate-like structure, with outer protrusions at both ends, which can be clamped on the assembly platform 1, and the three-jaw chuck support 13 is connected to the upper middle part of the positioning tool 14, the three-jaw chuck base 12 is connected to the three-jaw chuck support 13, and the three-jaw chuck 15 is connected to the three-jaw chuck base 12 and can rotate with it. The three jaws of the three-jaw chuck 15 can move synchronously, ensuring that the connection handle positioning has a high degree of concentricity. When the three-jaw chuck 15 needs to be fixed, the positioning pin of the three-jaw chuck support 13 (please mark which part this positioning pin is in the figure) fixes the three-jaw chuck base 12; when the three-jaw chuck 15 needs to be rotated, the positioning pin of the three-jaw chuck support 13 releases the fixation of the three-jaw chuck base 12. The connecting handle protection cover 16 is made of polyethylene material to prevent the three-jaw chuck 15 from damaging the surface quality of the connecting handle. The connecting handle protection cover 16 is not connected to the three-jaw chuck 15, but is just a clearance fit. The three support rods 5 with small balls are the handwheels of the connecting handle positioning tooling. The operator can rotate the connecting handle by turning the handwheel.

[0043] The punching device 6 is used to punch holes in the control rods.

[0044] The whole rotating assembly is used to realize the drilling of a group of 24 control rods in the control assembly. Figure 4 As shown, the 16 control rods of the outer ring can be divided into 4 batches, each with 4 rods; the 8 control rods of the inner ring can be divided into 4 batches, each with 2 rods. After the punching device completes the punching of the 4 control rods of the outer ring in sequence, the control assembly is rotated by a certain angle as a whole, so that the guide hole of the inner ring punching positioning tool rotates to the Z axis direction, and the punching device completes the punching of the 2 control rods of the inner ring in sequence. Repeat the above action 4 times to complete the punching work of the control assembly.

[0045] The drill bit of the punching device 6 is positioned and punched through the guide hole of the punching positioning tool 11, which can ensure that the axial position of the 24 holes (with the end of the control rod) is consistent. At the same time, the V-shaped positioning design of the punching positioning tool can ensure that the punching position is at the highest point of the cylindrical surface of the control rod, that is, the circumferential positioning of the hole is accurate. In addition, the V-shaped positioning surface of the punching positioning tool is grooved to prevent metal chips from accumulating at the punching position during the punching process, which in turn causes metal chips to wrap around the drill bit and affect heat dissipation.

[0046] Figure 6This is the punching and positioning tool before the improvement. Due to its large size, the positioning tool before the improvement cannot achieve the positioning of all control rods at one time. After completing one punching, it needs to be disassembled and installed on the next control rod before continuing to punch, which is cumbersome. In addition, repeated disassembly leads to low consistency in the axial positions of the 24 holes. At the same time, since the positioning surface of the punching and positioning tool before the improvement is arc-shaped, it cannot guarantee that the punching position is at the highest point of the control rod, and the positioning is inaccurate. On the one hand, inaccurate punching positioning will affect the quality of the control component and even cause the control component to fail to meet the technical requirements; on the other hand, it will affect the secondary punching when the control component is repaired.

[0047] The present invention provides a control assembly assembly method, comprising the following steps:

[0048] Step 1: The control rod support plate 2, the support plate connecting shaft 3, and the punching guide plate 4 are placed on the assembly platform 1, and the punching positioning tool 11 is placed on the punching guide plate 4;

[0049] Step 2: Put all control rods in place on the first rotatable support plate 8 of the control rod support plate 2;

[0050] Step 3: The connecting handle positioning tool 5 is placed in place on the assembly platform 1;

[0051] Step 4: Place the connecting handle in place on the connecting handle positioning tool 5;

[0052] Step 5: Rotate the control rod and assemble the control rod and the connecting handle finger rod together through threaded connection;

[0053] Step 6: The control rod support plate 2 and the punching guide plate 4 are rotated synchronously through the support plate connecting shaft 3, and the connecting handle positioning tool 5 rotates along with the punching guide plate 4, thereby realizing the assembly of all control rods and the connecting handle;

[0054] Step 7: Fix the control rod support plate 2, the punching guide plate 4, and the connection handle positioning tool 5, and use the punching positioning tool 11 to assist in determining the punching position, and use the punching device 6 to punch holes in the control rods;

[0055] Step 8: After completing the drilling of one batch of control rods, release the fixed state of the control rod support plate 2, the drilling guide plate 4, and the connection handle positioning tool 5;

[0056] Step 9: Rotate the control rod support plate 2, the punching guide plate 4, and the connection handle positioning tool 5, and repeat steps 7) to 9) until all control rods are punched;

[0057] Step 10: Spot weld the pins of the control assembly.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that modifying the technical solutions described in the aforementioned embodiments, or replacing some or all of the technical features therein by equivalents, does not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
