A lathe clamping tool for removing rudder blades

Abstract

The utility model provides a lathe clamping tool for the rudder blade that does not need to be disassembled, which solves the problem of low work efficiency of the current rudder stock maintenance method. It is characterized by: it also includes a clamping block for cooperating with a clamping claw, a clamping groove is provided on one side of the clamping block, and threaded holes are provided on both sides of the clamping groove; a tightening bolt is used to cooperate with the threaded hole; and a counterweight is arranged on the turntable. The rudder blade cooperates with the clamping groove, and then the rudder blade is tightened by the tightening bolt, and then the clamping claw clamps the clamping block. Since the rudder blade is an eccentric part, the counterweight is finally adjusted to ensure that the turntable remains in a balanced state when rotating, avoid the generation of unbalanced torque, and ensure the maintenance quality of the rudder stock. This tool does not require the rudder stock to be disassembled and assembled, which can effectively improve work efficiency.

Description

Technical Field

[0001] The utility model relates to the technical field of ship parts processing tooling, in particular to a lathe clamping tooling for non-disassembly of rudder blades. Background Art

[0002] The part of the rudder stock that matches the rudder sleeve will wear out during long-term operation, so the rudder stock needs to be repaired. The repair of the rudder stock is generally to cut a cut at the worn part, then pile it up through laser welding, and then turn it to the required size. One end of the rudder stock is connected to the rudder blade. Due to the irregular structure of the rudder blade, it cannot be directly clamped and processed. When the rudder stock is repaired, the rudder blade needs to be removed and installed again when the rudder stock is repaired. This operation method is not only time-consuming and labor-intensive, but also cannot guarantee the accuracy of the rudder blade reinstallation. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the utility model provides a lathe clamping tool for a rudder blade that does not require disassembly, thereby solving the problem of low working efficiency of the current rudder stock maintenance method.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A lathe clamping tool for a rudder blade that does not require disassembly, comprising a frame, a turntable is arranged on the frame, and claws are arranged in the circumference of the turntable, and further comprising:

[0006] A clamping block, used to cooperate with the clamping claw, wherein one side of the clamping block is provided with a clamping groove, and both sides of the clamping groove are provided with threaded holes;

[0007] Jack bolts, used to cooperate with threaded holes;

[0008] The counterweight is arranged on the turntable.

[0009] A buffer pad is provided between the contact surface between the tightening bolt and the rudder blade.

[0010] A plurality of through holes are evenly distributed on the bottom of the card slot.

[0011] The clamping block is made of stainless steel.

[0012] The distance from the counterweight to the center of the turntable is adjustable.

[0013] The rotating disk is evenly distributed with T-shaped slots in the circumference, and a sliding block is arranged in the T-shaped slot, and the counterweight block is connected with the sliding block by bolts.

[0014] The contact surface between the clamping claw and the clamping block is provided with anti-slip grooves.

[0015] The beneficial effects of the utility model are:

[0016] The rudder blade is matched with the slot and then tightened by the tightening bolt, and then the clamping claw clamps the clamping block. Since the rudder blade is an eccentric part, the counterweight is finally adjusted to ensure that the turntable remains balanced when rotating, avoid unbalanced torque, and ensure the maintenance quality of the rudder stock. This tooling does not require disassembly and assembly of the rudder stock, which can effectively improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0023] In the embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a lathe clamping tool for a rudder blade that does not require disassembly comprises a frame, a turntable 1 is provided on the frame, and claws 2 are provided in the circumference of the turntable 1, and further comprises:

[0024] A clamping block 3 is used to cooperate with the clamping claw 2. A clamping slot 4 is provided on one side of the clamping block 3, and threaded holes 5 are provided on both sides of the clamping slot 4.

[0025] A tightening bolt 6, used to cooperate with the threaded hole 5;

[0026] The counterweight block 7 is arranged on the turntable 1 .

[0027] The rudder blade is matched with the card slot 4, and then the rudder blade is tightened by the tightening bolt 6, and then the claw 2 clamps the clamping block 3. Since the rudder blade is an eccentric part, the counterweight block is finally adjusted to ensure that the turntable 1 remains in a balanced state when rotating, avoid generating unbalanced torque, and ensure the maintenance quality of the rudder stock. This tooling does not require the rudder stock to be disassembled and assembled, and can effectively improve work efficiency.

[0028] In the embodiment, Figure 2 , Figure 4As shown, the contact surface between the jacking bolt 6 and the rudder blade is provided with a buffer pad 8. The buffer pad 8 is a copper pad or a rubber pad, which is used to protect the surface of the rudder blade and prevent the jacking bolt 6 from damaging the rudder blade.

[0029] In the embodiment, Figure 2 , Figure 4 As shown, the bottom of the card slot 4 is evenly distributed with a plurality of through holes 9, which are used to reduce the weight of the card block 3 and facilitate taking.

[0030] In the embodiment, the clamping block 3 is made of stainless steel. The clamping slot 4 in the clamping block 3 is not easy to rust, ensuring the matching between the clamping slot 4 and the rudder blade.

[0031] In the embodiment, Figure 2 , Figure 3 As shown, the distance from the counterweight block 7 to the center of the turntable 1 is adjustable. By moving the counterweight block 7 on the turntable 1, the balance point of the rudder bar with rudder blades of different weights can be adjusted.

[0032] In the embodiment, Figure 2 , Figure 3 As shown, the rotating disk 1 is evenly distributed with T-shaped slots 10 in the circumference, and a slider 11 is arranged in the T-shaped slot 10, and the counterweight block 7 is connected to the slider 11 by bolts. By loosening the bolts, the counterweight block 7 can be moved relative to the rotating disk 1, and the adjustment is convenient.

[0033] In the embodiment, Figure 3 As shown, the contact surface between the clamping claw 2 and the clamping block 3 is provided with anti-slip grooves 12 to increase the friction force of the clamping claw 2 and prevent the clamping block 3 from deviating relative to the clamping claw 2 after the clamping claw 2 clamps the clamping block 3.

[0034] Obviously, the above embodiments of the present invention are merely examples for illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to provide all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still fall within the scope of protection of the present invention.
