Detailed Description
The invention will be further described with reference to specific examples, which are intended to be illustrative only and not to limit the scope of the invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and such equivalents also fall within the scope of the appended claims.
Referring to fig. 1 to 4, the assembly structure diagram a, the disassembly state diagram of the locking pin 6, the assembly structure diagram B, the disassembly state diagram of the guide ring 7, the right end of the tool is disposed inside the spindle seat 9, the guide ring 7 is disposed at the edge of the inside of the spindle seat 9, the locking pin 6 is disposed inside the guide ring 7, because of long service time, the occurrence of corrosion, deformation of the guide ring 7, and locking of the locking pin 6, which is very difficult to disassemble, the locking pin 6 is connected with the tool, the tool includes a screw 1, a nut 2, a support plate 3, a hollow jack 4, a base 5, both ends of the screw 1 are provided with external thread sections, the terminal of the screw 1 is provided with a smooth section, the outside of the screw 1 is provided with the base 5, the side of the base 5 is provided with the hollow, the side of hollow jack 4 is provided with backup pad 3, and hollow jack 4, backup pad 3 are passed respectively to screw rod 1, and the left end outside of screw rod 1 is connected with nut 2, and hollow jack 4 sets up between backup pad 3, base 5, and the internal thread hole has been seted up to the tip of fitting pin 6, and the right-hand member and the fitting pin 6 of screw rod 1 carry out threaded connection.
The screw rod 1 is used as a main part for pulling the locking pin 6 and is used for pulling the locking pin 6 to move together with a connecting piece, the supporting plate 3, the hollow jack 4 and the base 5 are sequentially connected in series by the screw rod 1 and are extruded on the side wall of the main shaft seat 9 through the nut 2, forming a temporary relatively fixed structure with the locking pin 6, when the operation of the jack 4 is started, the total length of the support plate is gradually increased, the length of the distance side between the support plate 3 and the base 5 is caused by the extension of the two ends, the support plate 3 is limited by the nut 2 and the hollow jack 4 in two directions and can not move, so that the relative positions of the support plate 3, the nut 2 and the screw rod 1 are not changed, therefore, the movement direction and the movement amount of the hollow jack 4 are transferred to the screw rod 1, the hollow jack 4 moves for a certain distance, and the right end of the screw rod 1 drives the locking pin 6 to move for a certain distance.
The frock is not only used for dismantling the fitting pin 6, still be used for dismantling guide ring 7, so the frock still includes fixed block 8, fixed block 8 carries out threaded connection with the right-hand member of screw rod 1, fixed block 8 sets up the one end outside at guide ring 7, the external diameter of fixed block 8 is greater than the internal diameter of guide ring 7 and is less than the internal diameter of spindle drum 9, after fitting pin 6 dismantles, guide ring 7 is inboard just hollow, screw rod 1 passes guide ring 7 and stretches out guide ring 7 right-hand member, through threaded connection fixed block 8, fixed block 8 plays a spacing effect, restriction guide ring 7 moves right for screw rod 1, in the time of screw rod 1 left motion, just can collude guide ring 7 out spindle drum 9 simultaneously through fixed block 8.
In order to smoothly and unhindered disassemble the locking pin 6 and the guide ring 7, the length of the screw rod 1 should satisfy the condition that the length is larger than the sum of the length of the hollow jack 4 in the contraction state, the thickness of the support plate 3, the thickness of the base 5, the thickness of the nut 2, the thickness of the spindle seat 9 and the thickness of the fixed block 8, because the screw rod 1 is used as a part for pulling the locking pin 6 and the guide ring 7, firstly, the screw rod needs to be connected to the locking pin 6 and the fixed block 8, and the other end needs to penetrate through all the parts and be locked by the nut 2 at the same time, so that enough length is needed, and if the length of the screw rod 1 cannot satisfy the condition, the disassembling work of the locking pin.
Before the guide ring 7 is disassembled, the damage and the deformation degree of the guide ring 7 can not be judged, if the guide ring is seriously deformed, the guide ring can not be smoothly disassembled, even if the guide ring is hooked to the edge of the left end of the spindle seat 9 by using a tool, the disassembly operation is equally bad, so in order to avoid troubles, the utility model discloses a round through hole is arranged at the middle part of the base 5, the diameter of the through hole is larger than the outer diameter of the guide ring 7, the hollow jack 4 comprises an inner cylinder body, the inner diameter of the inner cylinder body is larger than the outer diameter of the guide ring 7, the stroke of the inner cylinder body of the hollow jack 4 is larger than the thickness of the spindle seat 9, under the condition that the minimum size of the inner parts of the base 5 and the hollow jack 4 is larger than the outer diameter of the guide ring 7, the guide ring 7 can be always pulled outwards, even if the guide ring 7 is still difficult to be disassembled, is simple and labor-saving.
The utility model discloses a theory of operation:
1. the impeller lock locking pin is disassembled by firstly disassembling the impeller lock hydraulic cylinder body, installing the screw rod 1 on a locking pin screw hole, secondly installing the base 5, the hollow jack 4, the supporting plate 3 and the nut 2 on the screw rod 1, fastening the nut 2 to connect and fasten the base 5, the hollow jack 4 and the supporting plate 3, starting the hollow jack 4 again to drive the screw rod 1 to move, and moving the locking pin 6 along with the screw rod 1 until completely moving out of the spindle seat 9.
2. And (3) disassembling the guide ring 7, namely firstly disassembling the locking pin 6, penetrating the screw rod 1 through the spindle base 9 and firmly installing the screw rod 1 with the fixing block 8, secondly installing the base 5, the hollow jack 4, the supporting plate 3 and the nut 2 on the screw rod 1, fastening the nut 2 to connect and fasten the base 5, the hollow jack 4 and the supporting plate 3, starting the hollow jack 4 again to drive the screw rod 1 to move, and driving the guide ring 7 to move along with the screw rod 1 under the driving of the fixing block 8 until the guide ring is completely moved out of the spindle base 9.
The utility model discloses an adopt hollow jack 4 as power, take the fitting pin 6 that the corrosion blocked out and pull out guide ring 7 through fixed block 8 through screw rod 1, operation process is direct, simple and convenient, has realized dismantling the fitting pin 6 of impeller lock smoothly, and the maintenance of the impeller lock of being convenient for and guide ring 7 saves operating time, improves work efficiency, is applicable to the function of multiple situations such as corrosion, deformation.
