[0020] In order to make the purpose and advantages of the present utility model more clear and understandable, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the specific scope of protection claimed by the present utility model.
[0021] As Figure 1 、 Figure 3 - 5 shown, a lifting and adjusting device for a high-precision numerically controlled mechanical equipment includes a sliding seat 1. An electromagnet 103 is fixedly assembled on the top of the sliding seat 1. A motor 102 is fixedly assembled on the top of the electromagnet 103. A lead screw 101 is rotatably connected inside the sliding seat 1. The electromagnet 103 is connected in series with the motor 102 through an internal circuit. Elastic columns one 111 are symmetrically and fixedly connected to the inner wall of the sliding seat 1. The sliding seat 1 is elastically connected with a wedge plate two 115 through the elastic columns one 111. One side of each wedge plate two 115 is fixedly connected with a telescopic rod 110. The sliding seat 1 is symmetrically provided with sliding grooves two 112 on one side for the telescopic rods 110 to slide. The common end of the telescopic rods 110 located outside the sliding seat 1 is magnetically adsorbed by the electromagnet 103.
[0022] According to the above structure, when the motor 102 is powered off, the lead screw 101 cannot be continuously controlled. Since the electromagnet 103 is connected in series with the motor 102, the electromagnet 103 is also powered off at the same time. When the electromagnet 103 is powered off, it can no longer adsorb the telescopic rod 110, and the telescopic rod 110 rebounds under the pulling force of the elastic column one 111, driving the wedge plate two 115 to rebound.
[0023] Referring to the attached Figure 1 - 2 、 Figure 5 - 6 , the output end of the motor 102 is fixedly connected to the lead screw 101. A slide table 104 is threadedly connected to the outer wall of the lead screw 101 and located outside the sliding seat 1. Connecting plates 107 are fixedly connected to both sides of the slide table 104. An elastic column two 113 is slidably connected to the inner wall of the sliding seat 1. One end of the elastic column two 113 is fixedly connected to a wedge plate one 114. The wedge plate one 114 is movably and fittingly arranged on one side of the wedge plate two 115. One end of the wedge plate one 114 is fixedly connected to a movable rod 108. The movable rod 108 slidably penetrates through one end of the connecting plate 107. The sliding seat 1 is provided with sliding grooves one 105 on both sides for the movable rod 108 to slide. A fitting plate 109 is fixedly connected to the outer wall of the movable rod 108 and located on one side of the sliding seat 1. Fitting grooves 106 for the fitting plate 109 to be fitted are fixedly connected to both sides of the sliding seat 1 at equal intervals.
[0024] According to the above structure, the second wedge plate 115 rebounds and no longer fits the first wedge plate 114. Without the obstruction of the second wedge plate 115, the first wedge plate 114 expands and contracts under the elastic force of the second spring column 113, driving the first wedge plate 114 to slide into the interior of the slide base 1. The first wedge plate 114 drives the movable rod 108 to slide, and the movable rod 108 drives the embedded plate 109 to embed into any one of the embedded grooves 106, thereby preventing the connecting plate 107 and the slide table 104 from dropping. The opening of the first sliding groove 105 and the sliding connection between the second spring column 113 and the slide base 1 are both for facilitating the reciprocating movement of the slide table 104 on the outer wall of the lead screw 101. The present utility model controls the telescopic sliding of the embedded plate 109 through the electromagnet 103. When power failure occurs, the embedded plate 109 can be buckled into the embedded groove 106, thereby preventing the slide table 104 from dropping, avoiding wear of the processing tool caused by accidental falling of the slide table 104, and preventing defects and damages to the processed part caused by the impact and friction between the processing tool and the processed part.
[0025] The working principle of the present utility model is as follows: When the motor 102 is powered off, it can no longer control the lead screw 101. Since the electromagnet 103 is connected in series with the motor 102, the electromagnet 103 is powered off simultaneously. When the electromagnet 103 is powered off, it can no longer adsorb the telescopic rod 110, and the telescopic rod 110 rebounds under the pulling force of the first spring column 111, driving the second wedge plate 115 to rebound; the second wedge plate 115 rebounds and no longer fits the first wedge plate 114. Without the obstruction of the second wedge plate 115, the first wedge plate 114 expands and contracts under the elastic force of the second spring column 113, driving the first wedge plate 114 to slide into the interior of the slide base 1. The first wedge plate 114 drives the movable rod 108 to slide, and the movable rod 108 drives the embedded plate 109 to embed into any one of the embedded grooves 106, thereby preventing the connecting plate 107 and the slide table 104 from dropping. The opening of the first sliding groove 105 and the sliding connection between the second spring column 113 and the slide base 1 are both for facilitating the reciprocating movement of the slide table 104 on the outer wall of the lead screw 101.
[0026] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in the art.
