[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] See also Figure 1-3The utility model provides a balancing counterweight device for a CNC lathe, comprising a machine tool spindle 1, a fixed sleeve 2, a support seat 3, a connecting groove 4, two connecting components 5 and a counterweight piece 6. The fixed sleeve 2 is arranged on the machine tool spindle 1, the support seat 3 is arranged on the outer wall of the fixed sleeve 2, the connecting groove 4 is arranged on the top of the support seat 3, two connecting components 5 are arranged on the left and right sides of the connecting groove 4, and the two connecting components 5 are arranged symmetrically. The connecting groove 4 is connected to the counterweight piece 6 through the two connecting components 5. The counterweight piece 6 comprises a counterweight block 61 and a connecting seat 62. The connecting seat 62 is arranged at the bottom of the counterweight block 61, and the connecting seat 62 is movably inserted into the connecting groove 4, and the left and right sides of the connecting seat 62 are provided with card slots.
[0017] Specifically, the connecting component 5 includes a bracket 51, a spring 52, a movable plate 53, a pull rod 54 and a block 55. The bracket 51 is arranged on the right side outside the connecting groove 4, one end of the spring 52 is connected to the right side inside the bracket 51, the right side of the movable plate 53 is connected to the other end of the spring 52, one end of the pull rod 54 is connected to the right side of the movable plate 53, and the pull rod 54 is movable through the inner side of the spring 52 and the right side of the bracket 51 respectively, and the block 55 is arranged on the left side of the movable plate 53, and the block 55 is movable through the right side of the connecting groove 4.
[0018] Specifically, a slope is provided on one side of the connection seat 62 that contacts the clamping block 55 , and the slopes of the two sides match each other.
[0019] Specifically, a handle 56 is provided at the other end of the pull rod 54 .
[0020] Working principle: First, when installing the counterweight 6, the staff only needs to align the connection seat 62 at the bottom of the counterweight 61 with the connection groove 4 and insert it. When the connection seat 62 is gradually inserted into the connection groove 4, its inclined surface will contact the inclined surface of the block 55 in the connection assembly 5 and produce extrusion. Since the block 55 is connected to the spring 52, the elastic action of the spring 52 enables the block 55 to shrink into the bracket 51 when it is squeezed, so that the connection seat 62 can pass smoothly. With the further insertion of the connection seat 62, when it completely enters the interior of the connection groove 4, the slot on the connection seat 62 will accurately correspond to the position of the block 55. At this time, the pressure of the spring 52 disappears, and the block 55 quickly returns to its original position under the restoring force of the spring 52, and smoothly enters the slot. This process realizes the stable fixation of the connection seat 62 and the entire counterweight 61, ensuring that it can work stably on the machine tool spindle 1 and play a balancing role. When the counterweight 61 needs to be disassembled, the staff only needs to pull the pull rod 54 in the connection assembly 5 outward. Since the pull rod 54 is connected to the moving plate 53, this action will drive the moving plate 53 to move rightward, thereby pushing the block 55 out of the slot. As the block 55 is disengaged, the fixed relationship between the connecting seat 62 and the connecting groove 4 is released, and the counterweight block 61 can be easily pulled out of the connecting groove 4 to complete the disassembly process.
