Description
Technical Field
[0001] The utility model relates to the technical field of excavator component processing, in particular to a placing rack for excavator component processing. Background Art
[0002] An excavator is an earth-moving machine that uses a bucket to dig materials above or below the supporting surface and load them into transport vehicles or unload them to stockpiles. An excavator is composed of many parts. The excavator turntable is one of the important parts of an excavator. Its main function is to support the excavator's rotating system so that the fuselage can rotate. The excavator turntable must be assembled during processing.
[0003] The existing excavator turntable steel ball assembly usually adopts a pure manual assembly method, and the assembly steps are as follows: the worker first puts the excavator turntable on the workbench, and then uses the right hand to install the nylon sleeve and the steel ball from the round hole of the outer ring of the excavator turntable into the inner ring in turn, to achieve a one-bead-one-set installation, and each time a set of beads is installed, the left hand is used to rotate the inner ring of the excavator turntable to install an appropriate amount of nylon sleeves and steel balls into the inner ring. The above assembly method still has shortcomings in actual use. For example, each time a set of beads is installed, the worker must insert the index finger of his right hand into the round hole of the outer ring of the excavator turntable, and use the finger to push the nylon sleeve and the steel ball to ensure that the nylon sleeve and the steel ball are completely installed in the inner ring. Long-term operation can easily cause discomfort to the worker's right index finger, and the worker's left and right hands must be operated at the same time during assembly, resulting in a high work intensity and easy fatigue of the worker, thereby indirectly reducing the assembly efficiency of the excavator turntable.
[0004] Therefore, a placing rack for processing excavator parts is particularly needed to solve the problems existing in the prior art. Utility Model Content

The sliding plate is engaged with the guide rod I, so that the guide rod I is fixed inside the support plate, and at least one spring II is connected between the sliding plate and the support plate. The sliding plate is disengaged from the guide rod I by pulling upwards, so that the spring I assists the block to move outward, and then the support plate is rotated by the operation of the servo motor.
[0007] Optionally, a limit plate is also included. A symmetrically distributed semicircular limit plate is fixedly connected to the top of the workbench and is used to limit the turntable body. The limit plate is made of soft material.

The front end of the push rod 17 is connected to a connecting plate 1701 for auxiliary pushing by welding. The front side of the slide rail 14 is connected to a symmetrically distributed guide rod III18 by welding. The connecting plate 1701 slides between the two guide rods III18. The front end of the guide rod III18 is externally sleeved with a spring III19 for auxiliary resetting.

The servo motor 5, the support plate 6, The clamping block 7, the guide rod Ⅰ8, the spring Ⅰ9, the sliding plate 10, the guide rod Ⅱ11, the spring Ⅱ12 and the handle 13, the bottom of the workbench 2 is connected to the servo motor 5 by bolts, the output shaft of the servo motor 5 passes through the workbench 2, and is connected to the support plate 6 by welding, the left and right sides of the support plate 6 are slidably connected with the clamping block 7, the clamping block 7 is in the shape of a triangular gear, so that the clamping block 7 can be engaged with the trapezoidal gear of the inner ring of the turntable body 4, the side of the clamping block 7 in contact with the support plate 6 is connected to the guide rod Ⅰ8 by welding, the guide rod Ⅰ8 is slidably connected to the support plate 6, and the guide rod Ⅰ8 is provided with a spring Ⅰ9 for auxiliary resetting on the outside, and the two ends of the spring Ⅰ9 are respectively connected to the clamping block 7 and the support plate 6 is connected, a sliding plate 10 is slidably connected to the upper part of the support plate 6, and the sliding plate 10 is clamped with the guide rod Ⅰ8, so that the guide rod Ⅰ8 is fixed inside the support plate 6, and the top of the support plate 6 is connected with the guide rods Ⅱ11 distributed on the left and right by welding, the sliding plate 10 slides between the two guide rods Ⅱ11, and the spring Ⅱ12 is sleeved on the outside of the lower end of the guide rod Ⅱ11, at least one spring Ⅱ12 is connected between the sliding plate 10 and the support plate 6, and a ball handle 13 is connected to the center position of the top of the sliding plate 10 by welding, and the sliding plate 10 is disengaged from the guide rod Ⅰ8 by pulling upward, so that the spring Ⅰ9 auxiliary card block 7 moves outward, and then the support plate 6 is rotated by the operation of the servo motor 5.
[0023] Before using the placement rack, the operating frequency of the servo motor 5 is pre-set according to the assembly requirements of the turntable body 4. Initially, the spring Ⅰ9 is in a compressed state. First, the staff puts the turntable body 4 on the workbench 2, and the two limit plates 3 cooperate to play a limiting role, which is convenient for the staff to accurately place the turntable body 4, and then puts an appropriate amount of nylon sleeves and steel balls into the stacking track Ⅰ15 and the stacking track Ⅱ16 respectively. At this time, the nylon sleeves and steel balls are rolled into the slide rail 14 and aligned with the push rod 17 in a ratio, and then the handle 13 is held by hand to pull the sliding plate 10 upward, and the spring Ⅱ12 is stretched accordingly, so that the sliding plate 10 is disengaged from the guide rod Ⅰ8. At this time, the spring Ⅰ9 is restored to its original state, so that the guide rod Ⅰ8 drives the block 7 to move outward, so that the block 7 is engaged with the inner ring of the turntable body 4, and then the servo motor 5 is turned on. The operation of the servo motor 5 causes the output shaft to drive the support plate 6 to rotate, and then the block 7 drives the inner ring of the turntable body 4 to rotate. When the inner ring rotates to a suitable angle, the servo motor 5 stops Stop running, then use any one hand to pinch the connecting plate 1701 and push the push rod 17 backward, the spring III 19 is stretched, and the push rod 17 pushes the steel ball on the slide rail 14 into the nylon sleeve, and then pushes the nylon sleeve from the round hole of the outer ring of the turntable body 4 into the inner ring. At this time, the rear end of the push rod 17 extends into the round hole of the outer ring to ensure that the nylon sleeve is completely pushed into the inner ring, so as to achieve the effect of quickly installing one ball and one set, and improve the assembly efficiency of the turntable body 4, and then release the connecting plate 1701, the spring III 19 returns to its original state, and then the connecting plate 1701 drives the push rod 17 to move forward and reset. After the push rod 17 is reset, the nylon sleeve and the steel ball continue to roll into the interior of the slide rail 14 and are longitudinally aligned with the push rod 17. At the same time, the servo motor 5 continues to run to make the inner ring of the turntable body 4 rotate to a suitable angle. The staff repeats the above steps to continue to install one ball and one set. During the assembly process, the staff changes the other hand to push the push rod 17 backward, thereby avoiding the staff from using one hand to work for a long time.
[0024] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
