Description

Technical Field

[0001] The utility model relates to a translation mechanism, in particular to a collective doffing translation mechanism. Background Art

[0002] The collective doffing translation mechanism is a mechanism used to transport full bobbins out after grasping full bobbins from the spindle positions during the collective doffing of a ring spinning frame. For the specific structure, reference can also be made to the previously applied patent "A Collective Doffing Tube Grasping Device Translation Apparatus" (Publication No. CN218812351U). However, in the existing technology, a gear drive is used to achieve the lateral horizontal movement of the tube grasping crossbeam. The existing mechanism is a linear translation mechanism. Therefore, after the tube grasping translation, the distance between adjacent machines will become smaller, which also increases the safety hazards in the workshop. Content of the Utility Model

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a collective doffing translation mechanism, which adopts the structure of a pull rod to achieve the effect of rotational translation. At the same time, the structure of the rotational translation mechanism is relatively simple, and it is also convenient for use and maintenance.

[0004] The utility model provides the following technical solutions:

[0005] A collective doffing translation mechanism includes a tube grasping crossbeam installed with a plurality of tube graspers and a moving unit for driving the rotational translation of the tube grasping crossbeam. The moving unit is fixedly installed on the herringbone arm bracket, and it includes a tube grasping installation bracket, a main connecting plate, a pin shaft, a column, a connecting block, an electric push rod, a shaft rod, a hoop block, and a pull rod. One end of the main connecting plate is connected to the tube grasping installation bracket through the pin shaft. The tube grasping installation bracket is used to connect with the tube grasping crossbeam. The other end of the main connecting plate is rotatably installed on the column of the connecting block. A group of shaft rods is penetrated through the connecting block. The electric push rod is installed on the connecting block and is used to push and pull the shaft rod to move linearly horizontally. The shaft rod is located on one side of the tube grasping crossbeam and is used to limit the rotation of the tube grasping crossbeam. A group of hoop blocks is installed at one end of the shaft rod. The top of the hoop block is rotatably connected to a group of pull rods through a pin rod. The end of the pull rod is also rotatably connected to the pin shaft;

[0006] Thus, when the electric push rod pushes the shaft rod to move linearly, the main connecting plate can be rotated around the column through the pull rod at the top of the hoop block at the end of the shaft rod. At this time, because the tube grasping crossbeam is connected to the main connecting plate through the pin shaft, the tube grasping crossbeam can be synchronously driven to translate. And because there is only one set of rotation points, the tube grasping crossbeam can also be driven to rotate around the rotation point at the same time. Also, because the shaft rod is located on one side of the tube grasping crossbeam and is used to limit the rotation of the tube grasping crossbeam, therefore, the effect of rotational translation of the entire translation mechanism can be achieved, and the structure of the rotational translation mechanism is relatively simple, and it is also convenient for use and maintenance.

[0007] Preferably, both ends of the main connecting plate are respectively connected and installed outside the column and the pin shaft through copper sleeves to improve the wear-resistant use effect.

[0008] Preferably, a pin seat is provided on the pipe grasping installation bracket. The pin shaft is arranged vertically through the pin seat. A limiting plate is provided at its top end and overlaps on the pin seat. A nylon gasket is also sleeved outside the pin shaft and spaced at the gap between the top end of the main connecting plate and the pin shaft. And the pull rod is arranged at the bottom of the pin seat. Thus, the gravity of the pipe grasping cross beam is received on the main connecting plate through the nylon gasket. The setting of the limiting plate at the top end of the pin shaft can further ensure the stability of the pin shaft connection, and at the same time, disassembly and maintenance are relatively convenient.

[0009] Preferably, the herringbone arm bracket includes a long arm and a short arm in a herringbone shape. The top end of the long arm is connected to the connecting block, and its bottom end is hinged and installed on the pipe bracket. The pipe bracket is arranged parallel to the shaft rod. One end of the short arm is connected and installed in the middle of the long arm, and the other end is connected and installed on a set of pushing blocks. The pushing blocks are sleeved on the pipe bracket and move linearly along the pipe bracket under the drive of the driving member to adjust the height of the moving unit and the pipe grasping cross beam.

[0010] The beneficial effects of the present utility model are as follows: When the electric push rod drives the shaft rod to move linearly, the main connecting plate can be rotated around the column through the pull rod at the top of the hoop block at the end of the shaft rod. At this time, because the pipe grasping cross beam is connected to the main connecting plate through the pin shaft, the pipe grasping cross beam can be synchronously driven to translate. And because there is only one set of rotation points, the pipe grasping cross beam can also be driven to rotate around the rotation point at the same time. Also, because the shaft rod is located on one side of the pipe grasping cross beam to limit the rotation of the pipe grasping cross beam, therefore, the effect of the rotation and translation of the entire translation mechanism can be achieved, and the structure of the rotation and translation mechanism is relatively simple, and use and maintenance are relatively convenient.

Detailed implementation mode

[0018] As Figures 1-4 shown, a collective doffing translation mechanism, in this embodiment, includes a pipe-gripping crossbeam 1 equipped with a number of pipe grippers and a moving unit 2 for driving the rotation and translation of the pipe-gripping crossbeam 1. The moving unit 2 is positioned and installed on the herringbone arm support 3, and it includes a pipe-gripping mounting bracket 21, a main connecting plate 22, a pin shaft 23, a column 24, a connecting block 25, an electric push rod 26, a shaft rod 27, a clamping block 28 and a tie rod 29. One end of the main connecting plate 22 is connected to the pipe-gripping mounting bracket 21 through the pin shaft 23. The pipe-gripping mounting bracket 21 is used to connect with the pipe-gripping crossbeam 1, and the other end of the main connecting plate 22 is rotatably installed on the column 24 of the connecting block 25. A group of shaft rods 27 are passed through the connecting block 25. The electric push rod 26 is installed on the connecting block 25 and is used to push and pull the shaft rod 27 to move linearly horizontally. And the shaft rod 27 is located on one side of the pipe-gripping crossbeam 1 and is used to limit the rotation of the pipe-gripping crossbeam 1. A group of clamping blocks 28 are installed at one end of it. The top of the clamping block 28 is rotatably connected to a group of tie rods 29 through a pin rod, and the end of the tie rod 29 is also rotatably connected to the pin shaft 23;

[0019] Thus, when the electric push rod 26 pushes the shaft rod 27 to move linearly, the main connecting plate 22 can be rotated around the column 24 through the tie rod 29 at the top of the clamping block 28 at the end of the shaft rod 27. At this time, because the pipe-gripping crossbeam 1 is connected to the main connecting plate 22 through the pin shaft 23, the pipe-gripping crossbeam 1 can be synchronously driven to translate. And because there is only one set of rotation points, the pipe-gripping crossbeam 1 can also be driven to rotate around the rotation point at the same time. Also, because the shaft rod 27 is located on one side of the pipe-gripping crossbeam 1 and is used to limit the rotation of the pipe-gripping crossbeam 1, therefore, the effect of the entire translation mechanism rotating and translating can be achieved, and the structure of the rotating and translating mechanism is relatively simple, and it is also more convenient for use and maintenance.

[0020] Both ends of the main connecting plate 22 are rotatably installed outside the column 24 and the pin shaft 23 through copper sleeves respectively to improve the wear-resistant use effect.

[0021] A pin seat 211 is provided on the pipe-gripping mounting bracket 21. The pin shaft 23 is arranged vertically through the pin seat 211. A limiting plate 212 that overlaps on the pin seat 211 is provided at its top end. A nylon gasket 213 is also sleeved outside the pin shaft 23 at the gap between the top end of the main connecting plate 22 and the pin shaft 23. And the pull rod 29 is arranged at the bottom of the pin seat 211. Thus, the gravity of the pipe-gripping cross beam 1 is borne on the main connecting plate 22 through the nylon gasket 213. And the setting of the limiting plate 212 at the top end of the pin shaft 23 can further ensure the stability of the connection of the pin shaft 23. At the same time, disassembly and maintenance are also relatively convenient.

[0022] The herringbone arm bracket 3 includes a long arm 31 and a short arm 32 in a herringbone shape. The top end of the long arm 31 is connected to the connecting block 25, and its bottom end is hinged and installed on the pipe bracket 33. The pipe bracket 33 is arranged parallel to the shaft rod 27. And one end of the short arm 32 is rotatably installed in the middle of the long arm 31, and the other end is rotatably installed on a set of pushing blocks 34. The pushing blocks 34 are sleeved on the pipe bracket 33 and move linearly along the pipe bracket 33 under the drive of a driving member to adjust the height of the moving unit 2 and the pipe-gripping cross beam 1.

[0023] The working principle of the present utility model is as follows: When the electric push rod 26 drives the shaft rod 27 to move linearly, the main connecting plate 22 can be rotated around the column 24 through the pull rod 29 at the end of the shaft rod 27 located at the top of the hoop block 28. At this time, because the pipe-gripping cross beam 1 is connected to the main connecting plate 22 through the pin shaft 23, the pipe-gripping cross beam 1 can be synchronously driven to translate. And because there is only one set of rotation points, the pipe-gripping cross beam 1 can also be driven to rotate around the rotation point at the same time. And because the shaft rod 27 is located on one side of the pipe-gripping cross beam 1 and is used to limit the rotation of the pipe-gripping cross beam 1, thus, the effect of the rotation and translation of the entire translation mechanism can be achieved, and the structure of the rotation and translation mechanism is relatively simple, and use and maintenance are also relatively convenient.
