[0002] A pallet transfer machine is a device used for automatic handling during pallet production. When transferring and conveying pallets, the pallet transfer machine needs to transfer the pallet from one direction to another. Usually, a chuck structure is installed at the intersection of the longitudinal and transverse directions to chuck the pallet and then rotate it for transfer and conveyance. The existing chuck structure is a device installed on the pallet transfer machine to clamp the pallet and then transfer it. The chuck operation facilitates stable clamping and rotation operations, thereby improving the stability of the chuck when installed on the pallet transfer machine.

[0003] After the existing chuck structure is installed on the pallet transfer machine for use, it is directly exposed to the outside and placed, and a movable adjustment groove is provided on the upper surface of the disc body, which makes it easy for air to enter the inside through the surface of the disc body, and is not convenient for oiling and lubricating it during use. The bidirectional screw rod is easily corroded due to long-term contact with the air, and severe rust causes obstruction when it is re-engaged, making it inconvenient to continue using it, thereby affecting the convenience of oiling, lubricating and adjusting the chuck structure when it is installed on the pallet transfer machine for use. For this reason, the utility model proposes a chuck structure for a pallet transfer machine. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 6 The utility model provides a technical solution: a chuck structure of a pallet transfer machine, including a chuck structure main body 100, the chuck structure main body 100 includes a fixed base 101, the upper surface of the fixed base 101 is fixedly installed with two lifting cylinders 102 by bolts, the ends of the two lifting cylinders 102 are fixedly installed with rotating cylinders 103, and the ends of the rotating cylinders 103 are fixedly installed with a disk body 105 by bolts. When the chuck structure main body 100 is fixed to the pallet transfer machine for use, when the horizontal pallet transfer machine moves the pallet to the end and transfers it longitudinally, the lifting cylinder 102 raises the disk body 105, and the pallet enters the surface of the disk body 105;

[0025] A bidirectional screw rod 108 is rotated at the middle position of the inner part of the disc body 105. The end of the bidirectional screw rod 108 is located on the side of the disc body 105 and is fixed with a motor 104 by screws. A moving head 107 is provided at both ends of the bidirectional screw rod 108. The end of the moving head 107 is located on the surface of the disc body 105 and is fixed with a clamping plate 106 by bolts. The operation of the motor 104 drives the bidirectional screw rod 108 to rotate. The rotation of the bidirectional screw rod 108 moves the two moving heads 107 at the ends of the bidirectional screw rod 108 toward each other, so that the moving head 107 drives the clamping plate 106 to move and engage with the surface of the tray. The rotating cylinder 103 rotates it ninety degrees in the longitudinal transfer direction and continues to move forward. The chuck structure body 100 is also provided with:

[0026] An oil injection and lubrication mechanism includes an oil injection and lubrication mechanism including a connecting component arranged at the end of the moving head 107, an oil storage component arranged inside the connecting component, and an oil drainage component arranged on the inner surface of the oil storage component. When the chuck structure main body 100 is in use, the oil injection and lubrication mechanism can inject oil and lubricate the outer surface of the bidirectional screw rod 108, so that the bidirectional screw rod 108 can be adjusted smoothly when in use, and it is not easy to cause surface rust of the bidirectional screw rod 108 when not in use, thereby improving the convenience of oil injection, lubrication and adjustment when the chuck structure main body 100 is installed on the pallet transfer machine.

[0027] In order to facilitate the lubrication of the drainage brush 1085 through the connecting assembly, in this embodiment, preferably, the connecting assembly includes a fixed cylinder 1081 fixedly installed at the end of the moving head 107 by bolts, and the bidirectional screw rod 108 passes through the interior of the fixed cylinder 1081, so that when the moving head 107 moves on the outer surface of the bidirectional screw rod 108, the fixed cylinder 1081 is driven to move and perform oiling.

[0028] In order to facilitate the storage of lubricating oil for drainage and lubrication through the oil storage assembly, in this embodiment, preferably, the oil storage assembly includes an oil storage channel 1083 opened inside the fixed cylinder 1081, and an oil filling port 1082 is provided on the upper surface of the fixed cylinder 1081, so that oil can be easily filled into the interior of the oil storage channel 1083 through the oil filling port 1082.

[0029] In order to facilitate the oiling and lubrication treatment of the surface of the bidirectional screw 108 through the drainage and oiling assembly, and to prevent rust from causing friction, in this embodiment, preferably, the drainage and oiling assembly includes an annular mesh plate 1084 fixedly mounted on the inner surface of the fixed cylinder 1081 by screws, and the inner surface of the annular mesh plate 1084 is provided with a drainage brush 1085, and the inner surface of the drainage brush 1085 is in contact with the outer surface of the bidirectional screw 108, so that after the interior of the oil storage channel 1083 is filled with oil, the oil is immersed into the interior of the drainage brush 1085 through the annular mesh plate 1084, and is drained to the surface of the bidirectional screw 108 by the drainage brush 1085, and the moving head 107 drives the drainage brush 1085 to move on the outer surface of the bidirectional screw 108, while facilitating the oiling and lubrication operation.

[0030] A stabilizing control mechanism is provided, and the stabilizing control mechanism includes a stabilizing control component arranged on the lower surface of the disk body 105 and the surface of the fixed base 101. The lower surface of the stabilizing control component is provided with a rolling component. When the chuck structure main body 100 is installed on the transfer machine for use, when the disk body 105 drives the pallet to rotate, the stabilizing control mechanism stabilizes the rotation of the disk body 105, which is easy to strengthen the support for stable rotation operation and improve the stability of the rotation adjustment when the chuck structure main body 100 is installed on the pallet transfer machine for use.

[0031] In order to facilitate a more stable rotation operation of the disk body 105 through the stabilizing control component, in this embodiment, preferably, the stabilizing control component includes a rotation groove 1053 opened on the lower surface of the disk body 105, and two rotation control blocks 1052 are arranged inside the rotation groove 1053. The rotation control blocks 1052 rotate with the inside of the rotation groove 1053. A fixed column 1051 is welded at the middle position of the lower surface of the rotation control block 1052. The bottom end of the fixed column 1051 is fixed to the surface of the fixed base 101 by welding. After the rotation control block 1052 is installed by the fixed column 1051, it is convenient for the rotation cylinder 103 to drive the disk body 105 to rotate, and the rotation control block 1052 and the inside of the rotation groove 1053 are rotated.

[0032] In order to facilitate smoother rotation between the rotation control block 1052 and the rotation groove 1053 through the rolling component, in this embodiment, preferably, the rolling component includes rolling grooves 1054 opened on both sides of the lower surface of the rotation control block 1052, and balls 1055 roll inside the rolling grooves 1054. The outer surface of the ball 1055 contacts the inner bottom end of the rotation groove 1053. When the rotation control block 1052 rotates inside the rotation groove 1053, the ball 1055 can be driven to roll inside the rolling groove 1054. At this time, the rotation control block 1052 is smoothly rotated and controlled through the rolling groove 1054, and is not easily obstructed during rotation control.

[0033] The working principle and use process of the present invention are as follows: before using the chuck structure of the pallet transfer machine, first, the chuck structure main body 100 is placed on the installation position of the pallet transfer machine through the fixed base 101 and fixedly installed. When used after installation, when the horizontal pallet transfer machine moves the pallet to the end and transfers it longitudinally, the lifting cylinder 102 raises the plate body 105, and the pallet enters the surface of the plate body 105. The motor 104 drives the bidirectional screw rod 108 to rotate. The bidirectional screw rod 108 rotates to move the two moving heads 107 at the ends of the bidirectional screw rod 108 toward each other, so that the moving head 107 drives the clamping plate 106 to move and engage with the surface of the pallet. The rotating cylinder 103 operates to rotate it ninety degrees in the longitudinal transfer direction. On the contrary, the plate body 105 is lowered by the lifting cylinder 102 until it is reset, and the pallet is placed on the longitudinal transfer machine and continues to be moved forward.

[0034] Then, when the chuck structure main body 100 is used after being fixed and installed, when the disc body 105 rotates, the rotation control block 1052 can rotate inside the rotation groove 1053, and the ball 1055 can contact the inner bottom end of the rotation groove 1053 and roll inside the rolling groove 1054, so that the rotation control block 1052 can be smoothly rotated inside the rotation groove 1053. This makes it less likely for the disc body 105 to become unstable when uneven force is applied to both sides temporarily during rotation adjustment, and it is easy to strengthen the support and stabilize the rotation operation, thereby improving the stability of the rotation adjustment when the chuck structure main body 100 is installed on the pallet transfer machine.

[0035] Finally, before the chuck structure body 100 is used, lubricating oil is injected into the oil storage channel 1083 through the oil filling port 1082. After the lubricating oil is injected, it enters the interior of the drainage brush 1085 through the motor 104, and is again drained to the surface of the bidirectional screw 108 through the drainage brush 1085. When the bidirectional screw 108 rotates and drives the moving head 107 to move on the outer surface of the bidirectional screw 108, it drives the drainage brush 1085 to be evenly oiled and lubricated at different positions on the outer surface of the bidirectional screw 108, which is more convenient for rotation and adjustment. When not in use, it is not easy to cause rust on the outer surface of the bidirectional screw 108 due to contact with air, thereby improving the convenience of oiling, lubrication and adjustment when the chuck structure body 100 is installed on the pallet transfer machine.

[0036] Although embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
