DETAILED DESCRIPTION

[0028] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] See also Figure 1-Figure 11As shown, a multi-station sliding platform of a NdFeB magnetic material cutting device includes a frame 1, a mounting seat 2 arranged on the frame 1 and used to place a workpiece, an XY displacement slide mechanism 3 for driving the mounting seat 2 to slide horizontally and vertically, a cutting machine 4 for cutting the workpiece clamped on the mounting seat 2, a lifting adjustment mechanism 5 for driving the cutting machine 4 to slide in a vertical direction, and a clamping mechanism 6 for fixing the workpiece on the mounting seat 2 at multiple positions with equal distances, the clamping mechanism 6 includes a plurality of displacement blocks 61 slidably arranged on the mounting seat 2 and a driving mechanism 7 for driving the displacement blocks 61 to move closer to and away from each other The multi-station sliding platform also includes a collecting mechanism 8 for shielding iron filings generated during cutting. The XY displacement slide mechanism 3 includes a second linear driver 911, whose end is connected to the first screw rod 912 through a coupling, and the external thread of the first screw rod 912 is connected to the first sliding seat 913. The first sliding seat 913 is fixed to the mounting seat 2 above, and the mounting seat 2 is provided with a third linear driver 914, whose output end is connected to the second screw rod 915 through a coupling, and the second screw rod 915 is threadedly connected to the mounting seat 2, and the second screw rod 915 and the mounting seat 2 are distributed laterally along the first sliding seat 913. The first sliding seat 913 and the mounting seat 2 are respectively arranged in the horizontal and longitudinal directions.

[0030] When the position of the cutting machine 4 needs to be adjusted vertically, the first linear drive 51 is started to drive the threaded rod 52 to rotate, and the cutting machine 4 is driven to move vertically through the corresponding mechanism. When the horizontal or longitudinal position of the workpiece is adjusted, the XY displacement slide mechanism 3 can be used for operation, that is, the first screw rod 912 drives the first sliding seat 913 to adjust the lateral position, and the second screw rod 915 drives the mounting seat 2 to adjust the longitudinal position. This coordination method not only improves the cutting accuracy, but also realizes the synchronous clamping and fixing of multiple workpieces, thereby improving work efficiency.

[0031] See also Figure 1-Figure 7 As shown, the lifting and lowering adjustment mechanism 5 includes a first linear drive 51 and a threaded rod 52; the first linear drive 51 is arranged on the frame 1; the input end of the threaded rod 52 is installed on the output end of the first linear drive 51 through a coupling, and the external thread of the threaded rod 52 is connected with a threaded block 53, and both ends of the threaded block 53 are provided with a mounting frame 54 that penetrates and extends to the top of the mounting seat 2, and the cutting machine 4 is arranged on the mounting frame 54.

[0032] When the position of the cutting machine 4 needs to be adjusted vertically, the first linear drive 51 is started and drives the threaded rod 52 to rotate. When the threaded rod 52 rotates, it can slide vertically through the threaded block 53 and the mounting bracket 54 connected by threads, thereby driving the cutting machine 4 close to the mounting seat 2 and cutting the workpiece clamped on the mounting seat 2.

[0033] See also Figure 4-Figure 5As shown, the driving mechanism 7 includes a rotary driver 71, a transmission rod 72 and a clamping plate 73; the rotary driver 71 is arranged on the mounting seat 2; the transmission rod 72 is rotatably mounted on the mounting seat 2 and connected to the output end of the rotary driver 71; the clamping plate 73 is arranged at one end of the displacement block 61, and a pair of limiting plates 76 are arranged on the mounting seat 2, and two guide rods 77 for limiting the sliding of the displacement block 61 in the horizontal straight direction are arranged between the pair of limiting plates 76, and the displacement block 61 and the guide rods 77 are clearance-matched.

[0034] When multiple workpieces need to be clamped on the mounting base 2 for cutting, the rotary driver 71 is started and then rotated through the transmission rod 72. When the transmission rod 72 rotates, it can drive several displacement blocks 61 and clamping plates 73 to move closer to or away from each other.

[0035] See also Figure 5-Figure 8 As shown, the driving mechanism 7 includes a cylindrical cam limiting roller 74 and a limiting groove 75; the cylindrical cam limiting roller 74 is rotatably arranged outside the transmission rod 72 and is coaxially fixed with the transmission rod 72; the limiting groove 75 is provided on the cylindrical cam limiting roller 74 and has a plurality of limiting grooves. The other end of the displacement block 61 is provided with a connecting limiting rod 78 that matches the notch between the limiting grooves 75. The connecting limiting rod 78 is fixed to the end of the displacement block 61, so that when the cylindrical cam limiting roller 74 rotates, the connecting limiting rod 78 is restricted by the limiting groove 75 to slide horizontally and linearly under the action of the limiting groove 75.

[0036] When the transmission rod 72 rotates under the drive of the rotary driver 71, it can drive the cylindrical cam limiting roller 74 to rotate synchronously. When the cylindrical cam limiting roller 74 rotates, it can rotate synchronously through a plurality of limiting grooves 75 corresponding to the position of the displacement block 61 opened through the outer wall. Since the end of the displacement block 61 is equipped with a connecting limiting rod 78 that cooperates with the notch in the limiting groove 75, the displacement block 61 can be adjusted at an equidistant distance in the horizontal straight line direction under the limitation of the guide rod 77, so as to achieve the effect of synchronously and equidistantly clamping multiple workpieces, and achieve the effect of clamping multiple workpieces at one time, and can prevent the workpiece from moving when being clamped and cut, thereby improving the cutting accuracy in disguise.

[0037] See also Figure 3-Figure 9 As shown, the collecting mechanism 8 includes a mounting plate 81 and a collecting box 82; the mounting plate 81 is arranged on the cutting knife; the collecting box 82 is slidably arranged in the mounting plate 81, and the mounting plate 81 is arranged on the mounting frame 54. A collecting groove 83 for iron filings to enter and pass through is provided below the mounting plate 81 near the top of the cutting knife, and an arc-shaped limiting groove 84 is provided on the collecting box 82 for iron filings to fly into the collecting box 82, and a mounting groove for the collecting box 82 to be pulled out and installed is provided on the mounting plate 81.

[0038] When the cutting motor is working, a large amount of iron chips will be generated. These flying iron chips can be collected through the collection groove 83 provided on the mounting plate 81 and fly into the collection box 82. The collection box 82 has a unique arc-shaped limiting groove 84, which can better guide the iron chips generated by cutting into the collection box 82 through the arc-shaped limiting groove 84. The user can easily pull the collection box 82 out of the mounting plate 81 by pulling, and then dump the iron chips accumulated in the collection box 82.

[0039] In addition to the above-mentioned collection method, the utility model also provides an implementation scheme for collecting iron filings using a vacuum generator. A vacuum generator can also be connected to the mounting plate 81, and the suction end of the vacuum generator is connected to the end of the collection box 82, so that the iron filings can be directly sucked into the collection box 82. At the same time, a filter screen is provided in the collection box 82 to separate the contact between the iron filings and the vacuum generator. The collection box 82 is quickly installed on the mounting plate 81 through the mounting groove or the corresponding fixing structure, which is convenient for users to replace and clean.

[0040] See also Figure 9-10 As shown, the collecting mechanism 8 further includes a pulling block 85 and a circular pulling hole 86 ; the pulling block 85 is disposed at the end of the collecting box 82 ; and the circular pulling hole 86 is opened on the pulling block 85 .

[0041] When dumping the iron filings collected and accumulated in the collection box 82, the collection box 82 can be pulled out of the outside of the mounting plate 81 by simply pulling the pulling block 85, and when pulling the pulling block 85, the circular pulling hole 86 can be hooked by a tool or hand.

[0042] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
