DETAILED DESCRIPTION

[0019] The following are examples and the attached Figure 1-3, the technical solution of the present invention is further specifically described.

[0020] A fixture for processing NdFeB magnets, comprising a long strip base 1:

[0021] The base 1 is provided with a mounting channel 2 whose two ends are connected with the outer side thereof, wherein a sliding opening 3 connected with the mounting channel 2 is provided at the top of the base 1, and a fixed plate 4 is provided at the top of the base 1 on one side of the sliding opening 3, wherein a movable plate 5 is provided at the top of the base 1 on the other side of the sliding opening 3, and a slider 6 passing through the sliding opening 3 is provided at the bottom of the movable plate 5, the slider 6 is connected to a cover plate 7 located in the mounting channel 2 and sealing the sliding opening 3, wherein the cover plate 7 is driven by a hydraulic rod 8, and the hydraulic rod 8 is provided in the mounting channel 2 on the same side as the fixed plate 4, wherein the end of the output shaft of the hydraulic rod 8 is connected to the cover plate 7 through a vertical rod, and the vertical rod is located directly below the slider 6.

[0022] A sealing plate 9 is provided on one side of the bottom of the movable plate 5, which is opposite to the sliding opening 3, wherein a slide groove 10 is provided on the bottom of the sealing plate 9 along its length direction, and a slide seat 11 is provided in the slide groove 10, and a screw rod 12 extending to the outside of the sealing plate 9 is provided on the slide seat 11, wherein a positioning groove 13 is also provided at the bottom of the slide seat 11, and a through hole 14 corresponding to the positioning groove 13 is provided on the top wall of the mounting channel 2, and a positioning rod 15 is provided in the through hole 14, wherein the positioning rod 15 is driven by an electric push rod 16.

[0023] In this embodiment, the lengths of the sealing plate 9 and the cover plate 7 are both greater than the length of the sliding opening 3 , and the widths of both are greater than the width of the sliding opening 3 . The sliding opening 3 is arranged between the hydraulic rod 8 and the electric push rod 16 .

[0024] like Figure 2 As shown, a strip groove 17 is provided at the bottom of the cover plate 7 along its length direction, wherein a roller group 18 with one end embedded in the strip groove 17 is provided at the top of the hydraulic rod 8. When the cover plate 7 moves, the strip groove 17 will be driven to slide on the pulley group 18, so that it will not affect the movement of the cover plate 7, and it can also support and fix the suspended end of the cover plate 7, so that the cover plate 7 fits more closely to the top wall of the installation channel 2 to seal the sliding opening 3.

[0025] like Figure 2 As shown, a fan 19 is arranged in an opening at one end of the installation channel 2. When the fan 19 works, the working environment of the equipment in the installation channel 2 can be guaranteed to prevent it from being in a high temperature state.

[0026] In this embodiment, the screw rod 12 is arranged parallel to the slide groove 10, wherein bearings for fixing the screw rod 12 are arranged on both side walls of the slide groove 10, and a handle is arranged at the end of the screw rod 12 outside the sealing plate 9, and a screw hole for the screw rod 12 to pass through is arranged on the slide seat 11, wherein the size of the slide seat 11 is adapted to the size of the slide groove 10.

[0027] like Figure 3 As shown, a mounting opening connected to the slide groove 10 is provided at the top of the sealing plate 9 along its length direction, wherein a transparent observation plate 20 is provided at the mounting opening, and a scale mark is provided on the observation plate 20. The observation plate 20 is convenient for observing the working condition when the rotating screw 12 drives the slide seat 11 to move, and the scale mark is convenient for timely understanding of the displacement amplitude of the slide seat 11.

[0028] The method of using the present invention is as follows: when in use, the product is placed on the top of the base 1 and is close to one side of the fixed plate 4, then the cover plate 7 is driven to move left by the hydraulic rod 8, wherein the cover plate 7 drives the slider 6 to move left in the sliding opening 3, and the slider 6 drives the movable plate 5 to move left, so that the product is clamped and fixed on the base 1 by the moved movable plate 5 and the fixed plate 4 for subsequent processing, and when the movable plate 5 moves, it will drive the sealing plate 9 to move together, so that the movable plate 5 will eventually drive the cover plate 7 and the sealing plate 9 to move during the reciprocating movement left and right, so that the cover plate 7 and the sealing plate 9 will block and seal the entire sliding opening 3, preventing debris above the base 1 from entering the installation channel 2 through the sliding opening 3 and affecting the operating conditions of various equipment.

[0029] When the movable plate 5 and the fixed plate 4 clamp the product, the positioning groove 13 on the slide seat 11 is aligned with the through hole 14, and the electric push rod 16 drives the positioning rod 15 to slide upward from the through hole 14 and embed into the positioning groove 13, thereby positioning the sealing plate 9 and the movable plate 5, preventing the hydraulic rod 8 from malfunctioning and causing the movable plate 5 to be slightly displaced and unable to clamp the product, so that the movable plate 5 and the fixed plate 4 can clamp the product well.

[0030] When processing products of different specifications and sizes, the slide 11 can be driven to slide in the slide groove 10 by rotating the screw rod 12 to adjust the position of the slide 11, so that when the movable plate 5 and the fixed plate 4 finally clamp the product, the positioning groove 13 on the slide 11 is just aligned with the through hole 14, so that the positioning rod 15 can slide out of the through hole 14 and insert into the positioning groove 13 to fix the sealing plate 9 and the movable plate 5.

[0031] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
