Description

Technical Field

[0001] The utility model relates to a processing device, in particular to a processing center with a workpiece that can be quickly disassembled and assembled. Background Art

[0002] The machining center evolved from the CNC milling machine. The biggest difference between the machining center and the CNC milling machine is that the machining center has the ability to automatically exchange machining tools. By installing different-purpose tools on the tool magazine, the machining tool on the spindle can be changed through the automatic tool changer during a single clamping, realizing multiple machining functions.

[0003] When the machining center processes a workpiece, it is necessary to clamp and position the workpiece. The existing fixtures on the machining center generally use screws or fixtures to fix the workpiece. For the fixing method with screws, the overall disassembly and assembly are troublesome, reducing production efficiency. For the fixing method with fixtures, the overall structure of the fixture is complex, which is not conducive to reducing equipment costs or installation and maintenance. Summary of the Utility Model

[0027] The chuck assembly 80 includes a positioning sleeve 81, a clamping block 87, a return spring 82, a first adjustment rod 83, a second adjustment rod 84, a third adjustment rod 85, an adjustment head 86, a first ball head 88 and a plurality of second ball heads 89. The positioning sleeve 81 and the third adjustment rod 85 are respectively installed at the orifices on both sides of the adjustment hole 71. The return spring 82 and the second adjustment rod 84 are arranged in the adjustment hole 71 and are clamped between the positioning sleeve 81 and the third adjustment rod 85. The positioning sleeve 81 is installed on the installation hole 72. The first adjustment rod 83 cooperates with the second adjustment rod 84 and extends into the clamping block 87. The first ball head 88 is arranged in the clamping block 87. The second ball heads 89 are arranged on the clamping block 87 and are in fit with the first ball head 88. The adjustment head 86 drives the third adjustment rod 85 to adjust the position on the function board 70. During the adjustment process of the third adjustment rod 85, the first adjustment rod 83 is driven by the second adjustment rod 84 to synchronously adjust the position. During the adjustment process of the first adjustment rod 83, the second ball heads 89 are driven by the first ball head 88 to extend out of or retract into the clamping block 87.

[0028] Specifically, an external thread is provided on the outer peripheral surface of the clamping block 87, and an external thread is also provided on the outer peripheral surface of the second adjustment rod 84. The clamping block 87 and the second adjustment rod 84 are respectively installed by fitting the external threads with the internal threads at the orifices of the adjustment hole 71. A notch is provided on the second adjustment rod 84, and an inclined guide surface 841 is provided at the bottom of the notch and is inclined. An inclined guide surface 831 is also provided at the bottom of the first adjustment rod 83. The inclined guide surface 841 on the second adjustment rod 84 and the inclined guide surface 831 on the first adjustment rod 83 are complementary in slope, and the inclined guide surface 831 on the first adjustment rod 83 is in fit with the inclined guide surface 841 on the second adjustment rod 84. A guide groove 871 extending inward is provided at the bottom of the clamping block 87, and the first adjustment rod 83 extends into the guide groove 871. In addition, a plurality of movable holes 872 are provided on the circumferential surface of the clamping block 87, the movable holes 872 communicate with the guide groove 871, and the movable holes 872 are evenly spaced on the circumferential surface of the clamping block 87.

[0029] During assembly, the first ball head 88 is fixedly installed at one end of the first adjusting rod 83 away from the inclined guide surface 831 by welding or other means. The first ball head 88 is arranged in the guide groove 871, and the second ball head 89 is arranged on the movable hole 872 and extends into the guide groove 871 to fit against the outer surface of the upper side of the first ball head 88. To prevent the second ball head 89 from easily falling off the clamping block 87, the first ball head 88 and the second ball head 89 are magnets with opposite magnetic polarities.

[0030] When clamping the workpiece, the workpiece is sleeved outside the clamping block 87 through the inner groove. When the first adjusting rod 83 drives the first ball head 88 to slide past the second ball head 89, the adjusting head 86 drives the third adjusting rod 85 to rotate. Through the cooperation of the internal thread and the external thread, the third adjusting rod 85 and the second adjusting rod 84 move inward. The second adjusting rod 84 squeezes the first adjusting rod 83 upward through the inclined guide surface 841, and the first ball head 88 simultaneously squeezes all the second ball heads 89, causing the second ball heads 89 to extend from the movable holes 872 and press the workpiece tightly. On the contrary, when it is necessary to loosen the workpiece, the third adjusting rod 85 is rotated in the reverse direction, and the return spring 82 squeezes the second adjusting rod 84 to return, and the first adjusting rod 83 releases the first ball head 88.

[0031] In this embodiment, the adjusting head 86 is a handle, and the third adjusting rod 85 is driven to rotate by rotating the handle. In other embodiments, the adjusting head 86 can be a motor, and the third adjusting rod 85 is driven to rotate by the motor. To prevent the second ball head 89 from falling into the guide groove 871, the maximum adjusting height of the second adjusting rod 84 for the first adjusting rod 83 is set such that the centers of the balls of the first ball head 88 and the second ball head 89 are in a horizontal position.

[0032] The beneficial effects of the workpiece quickly detachable and installable machining center of the present utility model are as follows: By arranging the clamping block 87, the first adjusting rod 83, the second adjusting rod 84, the third adjusting rod 85, the first ball head 88 and a plurality of second ball heads 89 on the chuck assembly 80, during the adjustment process of the third adjusting rod 85, the first adjusting rod 83 is driven to synchronously adjust through the second adjusting rod 84. During the adjustment process of the first adjusting rod 83, the second ball heads 89 are driven by the first ball head 88 to extend from or retract into the clamping block 87, so as to realize quickly fixing or loosening the workpiece, effectively improving the disassembly and assembly efficiency of the workpiece, and the overall structure is simple and convenient for maintenance.

[0033] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0034] The above-described embodiments merely represent several implementation manners of the present utility model.
