The present invention relates to an endless track having a structure for maximizing friction with the ground, and more particularly, to a method and apparatus for injecting grease and facilitating the assembly of a bushing used when connecting a link forming the endless track.

The endless track, which has a structure that maximizes friction with the ground, is mainly used as a power transmission wheel for civil special vehicles (blodzers, fork lanes) and military special vehicles (tanks, armored vehicles, etc.). The caterpillar is a structure in which links and links are repeatedly connected, and the connection configuration of each link is configured such that both ends of the pin inserted with the bush are inserted in the mutually mating portions of the link. As a method, a worker hits a pin with a hammer or a hand tool while artificially aligning one end of the pin with a hole formed in the bush so that the pin is inserted into the hole of the bush by the impact or the bush is mechanically pressed. It was fixed to the device, and the crankshaft of the press descended and inserted into the impact generated when hitting the pin in a state consistent with the hole of the bush.

Since this assembly method impacts one end of the pin several times, the tip end of the pin is distorted and the straightness of the pin is deformed. Such a shape deformation of the pin prevents the state of being inserted into the hole of the bush. This caused problems such as not suitable for linking after assembly.

In addition, in the configuration of the bush and the pin connecting the caterpillar link, grease is injected into the gap between the pin and the bush in order to reduce the resistance to rotational friction, and a high viscosity grease is injected due to the narrow gap between the pin and the bush. There was a problem that was not easy to do.

Therefore, in the case of handling the conventional endless track connection bushing and pins, it is required to easily assemble the pins and bushes. In addition, in the state where the pins and bushes are assembled, the grease is easily formed by the gap formed between them. Clean injection configuration was required.

The present invention created to solve such a conventional problem is to stabilize the assembly of the pin and bush in a state in which smoothly and stably supplying the supply of the pin and the bush processed to the design dimensions as well as the gap between the pin and the bush The purpose is to supply grease easily.

The object of the present invention is to supply the bush and the pin connecting the link of the caterpillar on the coaxial line, respectively, and the pin through the bush by the rod of the insertion member in the state in which the bush and the pin in a straight line supply And a loading step of moving the bushing in which the pin is inserted to the grease injection position, and injecting grease by the injection member into the other side gap of the bush while fixing one side of the bushing to the fixing member at the grease injection position. The grease injection step and the loading step after the grease injection are operated again to achieve the assembly method by sequentially performing the discharge step of moving the bushing at the grease injection position to the inclined discharge plate side.

In addition, the present invention is provided on the side of the base is provided with a plurality of bushes and pins for the link assembly of the caterpillar track supply member for supplying each of the bushes and pins coaxially to the assembly position of the base, the bush and the pin It is supplied on this coaxial and the assembly block member consisting of each block to induce the stability of the bushing and the insertion and stop of the pin, and to stabilize the assembled bushing and pin at a predetermined interval horizontally with the assembly block member to supply grease An injection member for injecting grease into the gap between the pin and the bush through a cap of a grease injection block member and a rod installed coaxially with respect to the grease injection block member and coupled to and separated from the bush, and the assembly block The member, a moving hole formed to cross the space of the grease injection block member, and the moving hole is provided at a set groove position of the first supporting block and the second supporting block.

According to the present invention having the above configuration, when the cylinder 250 of the supply member 200 is operated in an extended state, each of the hoppers 220 and 230 rotates upward from the hinge pin 240. Each hopper 220, 230 is in an inclined state, and at the same time, the storage unit 250, which is a loading space, is also in an inclined state.

When the pin P and the bush B are supplied and loaded into the space of each of the inclined hoppers 220 and 230, the pin P and the bush B enter the moving hole 106 of the base 100. When the cylinder 270 of the platform 260 is operated, the platform 260 is lowered and one bush B and the pin P are elevated. In the state passing through 260 is supplied to the settle groove 312 formed in the first support block 301 of the assembly block member 300 installed in the moving hole 103 of the base 100.

In this supply step (S100), the supply state of the bush (B) is placed on the first support block 310 and is in a state crossing the upper portion of the moving hole (103). In addition, the supply state of the pin (P) forms a state supplied to the slide groove 310 of the guide block 320 installed in coaxial with the first support block 310, the center of the pin (P) bush It is in a state of being placed in parallel with the axis line of the through hole formed in (B).

As described above, when the pin P and the bush B are supplied side by side on the coaxial line of the assembly block member 300, the first supporting block 310 detects the state of the bush B as an electric signal.

When the insertion of the pin P is stopped by the bolt 353, it is determined that the insertion is completed, and the push rod 331 in the forward state is returned to its original position by the push cylinder 330 which is retracted and then stopped. do.

When inserting the pin P as described above, the bush B placed on the settling groove 312 of the first support block 310 may be released from the settling groove 312 by the insertion pressure of the pin P. However, since the end of the bushing (B) on the back surface of the first support block 310 is blocked by the settling jaw 315 of the fixed block 313, the assembling step (S100) is performed while maintaining a stable state.

When the push rod 331 returns, the lifting plate 640 is lifted by the lifting cylinder 650 in the loading step S300 in which the loading member 600 located in the moving hole 103 space is driven by an electrical signal. Will be achieved.

When the lifting plate 640 ascends, the moving block 660 moves up and down from the bottom of the moving hole 103 of the base 100, and the bush in a state crossing the first supporting block 310 in the process of lifting up and down. (B) is in a state of lifting and stops.

When the bush B is lifted by the movement of the moving block 660 as described above, the rod is moved in the shrinking direction by contracting in the loading cylinder 630 of the loading member 600, and the movable table 620 connected to the rod. It is also a state moving in the contraction direction.

When the moving table 620 is moved by the loading cylinder 630 in the contracting direction, the lifting plate 640 having the moving block 660 installed on the moving table 620 is also moved, so that the moving block 660 moves. The lifted bush B stops when reaching the position of the second support block 410 by moving in the contracting direction of the loading cylinder 630, that is, the exit direction of the moving hole 103.

When the movable block 660 stops at the second support block 410, the lifting cylinder 650 of the loading member 600 starts the contracting operation, and the movable block 660 is the movable hole 103 of the base 100. Descend from top to bottom.

When the movable block 660 is lowered, the bush B lifted by the movable block 660 is guided toward the settling groove 415 of the natural second support block 410 and the bolt 453 of the stopper 450. In the continuous lowering operation, the bush B is placed in the settled groove 415 of the second support block 410. Thereafter, the contraction operation of the lifting cylinder 650 is stopped and waits for the next signal.

When the bush B is placed in the settling groove 412 of the second support block 410 by the movable block 660, the injection member 500 operates by an electrical signal to perform the grease injection step S300. .

The cylinder 510 operating by the electrical signal of the injection member 500 moves the rod 513 in the extending direction, and the nozzle cap 520 is installed at the front end by the rod 513. 2 is moved toward the bushing (B) settled in the settling groove 412 of the support block 410.

As the rod 513 moves in the extension direction, the nozzle cap 520 is engaged with the pin groove 521 of the nozzle cap 520 to the pin P of the bush B placed in the settling groove 512. The operation of the cylinder 510 is stopped.

At this time, one end of the bush (B) is in a state that is caught by the fixing jaw 415 of the fixed block 413 of the second support block 410, the pin (P) is in contact with the bolt 453 of the stopper 450 In this case, the mating state of the bushing B and the nozzle cap 520 is maintained in a stable state.

In the state where the nozzle cap 520 is engaged with the bush B, when grease is supplied between the parts to be joined, external force due to grease injection is applied laterally, so that a bearing force for protecting the nozzle cap and the bushing part is increased. Since it is required, the fixing cylinder 490 operates in the upper plate 480 installed in the upper space of the second support block 410 and the fixed block 413, the state in which the fixed tip 470 moving in the extension direction is lowered. In the lowered state, the fixing tip 470 forms a state of pressing the upper surfaces of the bushes B and the pins P located in the settling groove 413 and the settling jaw 415, and the operation of the fixed cylinder 490. Is stopped and the support state of the bush B is stabilized by the pressing action of the fixing tip 470.

Through the nozzle hole 522 of the nozzle cap 520 is injected into the gap between the bush (B) and the pin (P) is filled with grease.

Since grease is supplied by grease by external force in the state where the nozzle cap 520 is fitted at one end of the bush, the outer peripheral surface of the bush serves to maintain a clean state because no peripheral contamination occurs due to grease injection.

When the grease injection is completed, the fixed cylinder 490 providing the force for pressing the bushing B and stopping the driving of the grease supply member and the cylinder 510 of the injection member 500 are converted by an electrical signal. Start the contraction action.

Accordingly, the second support block is fixed because the fixed cap 470 holding the surface of the bush B and the nozzle cap 520 formed at one end of the bush B are separated from the bush B and returned to their original positions. In the settling groove 413 of 410, the bush B is free.

When the fixing cap 470 and the return of the nozzle cap 520 are completed, the loading step (S300) is driven once again by an electrical signal, and the lifting cylinder 650 is driven, and thus the lifting plate 640 moves up. do. As such, the moving block 660 of the lifting plate 640 moves upward from the lower portion of the moving hole 103 to the bush B located in the settling groove 412 while the lifting plate 640 performs the lifting operation. Lifting the movable block 660 to separate the bush (B) from the second supporting block (410).

In the state in which the bushing B is lifted by the movable block 660, the loading cylinder 630 of the loading member 600 contracts again so that the movable table 620 connected to the rod is moved toward the discharge member 700. A state of movement is achieved.

When the moving block 660 is moved toward the discharge member 700, the work position is moved to form a state in which the bush B enters the space between the slide plates 730 while lifting the bush B.

When the moving table 620 of the loading member 600 moves to the discharge member 700 side, the lifting cylinder 650 operates thereafter, such that the moving block 66 moves downward, and when the moving block 660 moves downward. Bush (B) heard in the state is naturally placed on the top of the slide plate 730 of the discharge member 700, the drive of the lifting cylinder 650 when the bush (B) is removed from the descending moving block 66 Is stopped, the driving of the loading cylinder 630 is started to move the moving block 660 to the assembly step (S100) position and stop.

The slide plate 730 of the discharge member 700 is inclined at a predetermined angle so that the bush B moved from the moving block 660 is clouded in an inclined direction and supplied to the next process. It works.

When the moving block 660 is moved to the assembly step (S100), the supply step (S) is newly started by an electrical signal.

As described above, in the present invention, when the bush B and the pin P are separated and supplied to the hopper, the pins can be smoothly assembled to the bushes by the respective steps and the configuration to perform the above steps. The gap between them allows the grease to be injected cleanly and transfer to the next process without the operator.
