Technical Field

[0001] The present invention relates to the technical field of anchor chain link deburring, and particularly to a rotary chain link deburring device. Background Art

[0002] During the deburring process of the anchor chain, the burrs at the welded joint are removed by the rotation of the deburring knife. The deburring steps of the rotary deburring machine are as follows: starting position of the rotating arm → clamping by the jaws → feeding → rotary deburring → ending position of the rotating arm → retracting the tool.

[0003] The patent document with the publication number CN104985253B discloses a large - specification high - strength anchor chain link welded joint finishing machine. The anchor chain link clamping device, the rotary deburring device, and the deburring power device are all arranged on the same vertical side of the fuselage. The anchor chain link clamping device is arranged on both sides of the U - shaped notch in the middle of the upper end of the fuselage. The rotary deburring device is arranged outside the anchor chain link clamping device. The deburring power device is arranged at the lower end of the fuselage, and the deburring power device is connected to the rotary deburring device through a rotating frame. During the feeding process of the deburring knife of this device, due to the reaction force of feeding, it is easy to cause elastic deformation of the rotating arm, thereby affecting the deburring accuracy. The deburring power device is arranged at the lower right part of the fuselage, using the non - rod cavity to bear force, with a large volume and occupying a large space on the site. The oil cylinder is connected to the rack and the piston rod of the oil cylinder is connected to the piston rod through threads, with low connection strength, affecting the normal operation of the deburring machine. Summary of the Invention

[0004] The purpose of the present invention is to solve the above - mentioned technical problems and provide a rotary chain link deburring device.

[0005] In order to achieve the above - mentioned technical purpose and meet the above - mentioned technical requirements, the technical solution adopted by the present invention is: a rotary chain link deburring device, including a fuselage and a rotating arm. The rotating arm is connected to the upper bearing seat and the lower bearing seat through a rotating shaft. An inserting knife oil cylinder is arranged at the upper end of the rotating arm, and a deburring knife is arranged at the right end of the inserting knife oil cylinder. The deburring knife is pushed by the inserting knife oil cylinder to insert into the center position of the anchor chain link welded joint for rotary deburring. A limiting component is arranged below the rotating arm to support the rotating arm and prevent elastic deformation of the rotating arm caused by the reaction force of feeding. The limiting component includes a support seat, a groove plate is arranged on the support seat, a sliding plate is arranged on the groove plate, one side of the sliding plate is connected to a limiting plate through a horizontal pressing screw and a horizontal tension screw. The sliding plate is pushed by the horizontal pressing screw and locked by the horizontal tension screw. A vertical movable plate is arranged on the sliding plate. A deburring oil cylinder is arranged below the starting position of the rotating arm. The deburring oil cylinder bears force on the rodless cavity. The front end of the oil cylinder piston rod is connected to a straight rack through a key, and the straight rack meshes with a gear.

[0006] Preferably: the upper plane of the sliding plate and the lower plane of the vertical movable plate are mutually - matching inclined planes, and the vertical movable plate is adjusted to the position matching with the rotating arm to support the rotating arm.

[0007] Preferably, the vertical movable plate is connected to the sliding plate by vertical locking screws.

[0008] Preferably, the straight rack is arranged in the sliding tooth groove, and the gear is arranged on the rotating shaft.

[0009] Preferably, the anchor chain link is clamped and fixed by symmetrically arranged jaws.

[0010] Preferably, the piston and the piston rod of the deburring oil cylinder are of an integral structure.

[0011] Preferably, the limit assembly is fixed to the machine body through a fixing plate.

[0012] Compared with the traditional structure, the beneficial effects of the present invention are as follows:

[0013] 1. The structure of the present invention is reasonably designed. By setting the limit assembly, the rotating arm can be supported to prevent its deformation under force during the feed process, so that the deburring knife can be stably inserted into the center position of the weld joint. The limit is stable and reliable, preventing the elastic deformation of the rotating arm caused by the reaction force of the feed, ensuring the deburring accuracy of the weld joint surface, and reducing the grinding labor intensity of workers.

[0014] 2. The structure of the present invention is compact. The deburring oil cylinder is installed below the starting position of the rotating arm of the deburring machine, and the force on the rodless cavity is adjusted to the force on the rod cavity, which can reduce the volume of the deburring machine, save the manufacturing cost of the equipment, save the site space, and solve the requirement of the deburring machine for the site space.

[0015] 3. The present invention has high strength and is safe and reliable in use. The connection method between the deburring oil cylinder and the straight rack is changed from the original threaded connection to the keyway connection at the front end of the piston rod of the oil cylinder. This connection method can meet the connection strength requirements between the piston rod and the straight rack; combining the piston and the piston rod of the oil cylinder into an integral part can effectively avoid the influence of the strength of the threaded connection.
