DETAILED DESCRIPTION
[0021] like Figures 1 to 3 As shown, the utility model is an interchangeable tooling for a CNC machining center, comprising a machine body 1, and a processing device 3 for processing parts is connected to the top of the machine body 1. Cabin doors 2 are provided on both sides of the machine body 1 so that parts can be placed in the machine body 1, and the cabin doors 2 can be made of glass material to facilitate operators to observe the internal processing of the machine body 1. A slide groove 6 is provided on the upper part of the machine body 1, and a first slider 4 and a second slider 5 are slidably connected in the slide groove 6. There are multiple first sliders 4 and second sliders 5, and the upper parts of the multiple first sliders 4 are connected to the first loading plate 8, and the upper parts of the multiple second sliders 5 are connected to the second loading plate 10. The lower part of the first loading plate 8 is connected to a sliding block 12, and the sliding block 12 is slidably connected to the upper part of the machine body 1. The upper part of the machine body 1 is connected to a motor 11, and the output shaft of the motor 11 is connected to a threaded rod 13, and the threaded rod 13 passes through the sliding block 12 and is threadedly connected to the sliding block 12, and the first loading plate 8 is driven to move by the motor 11. The first loading plate 8 is connected to one side close to the second loading plate 10 with two clamping devices 7 for clamping the second loading plate 10. The two clamping devices 7 are located at both ends of the first loading plate 8 to clamp the second loading plate 10 at both sides.
[0022] like Figures 1-2As shown, the clamping device 7 includes: a telescopic rod 72, a fixed rod 75, a torsion spring 74, a rotating rod 71 and an arc rod 73. One end of the telescopic rod 72 is fixedly connected to the side of the first loading plate 8, and the telescopic rod 72 is used to reduce the impact force. The other end of the telescopic rod 72 is fixedly connected to the fixed rod 75. There are two rotating rods 71. The rotating rods 71 are arranged obliquely in a normal state, so that the rotating rods 71 can rotate when the rotating rods 71 contact the second loading plate 10. The fixed rod 75 passes through the two rotating rods 71 and is rotatably connected to the rotating rods 71. There are two torsion springs 74 respectively wrapped on the outside of the fixed rod 75. The two rotating rods 71 are respectively connected to the torsion springs 74. The rotating rods 71 can be reset by the torsion springs 74, and the rotating rods 71 can always be kept in an oblique arrangement. The two rotating rods 71 are each connected to an arc rod 73, and the two arc rods 73 are arranged in a staggered manner, and the second loading plate 10 is clamped by the arc rods 73. The lower part of the second slide block 5 is connected to an adjusting device 9 for controlling the movement of the second slide block 5. The upper parts of the first loading plate 8 and the second loading plate 10 are both connected to an electric cylinder 14, and the output end of the electric cylinder 14 is connected to a push plate 15 to clamp and fix the parts. The upper parts of the first loading plate 8 and the second loading plate 10 are both connected to a fence 16 to prevent the parts from contacting.
[0023] like Figures 1 to 4 As shown, the adjusting device 9 includes: a moving block 92, a screw 91, a rotating block 93, a fixed block 94, a retaining ring 97, a spring 96 and a stopper 95. The moving block 92 is slidably connected to the side of the second slider 5, and the screw 91 passes through the moving block 92 and is threadedly connected to the moving block 92. The screw 91 is slidably connected to the outer side of the second slider 5, and the other end of the screw 91 is threadedly connected to the rotating block 93. By rotating the rotating block 93, the rotating block 93 will contact the moving block 92, and the moving block 92 will no longer move. The fixed block 94 has two blocks, which are respectively arranged on both sides of the second slider 5. The stopper 95 has two blocks, which pass through one fixed block 94 and are slidably connected to the fixed block 94, and the stopper 95 will not fall through the fixed block 94. The stopper 95 passes through the retaining ring 97 and is fixedly connected to the retaining ring 97. The spring 96 is located between the fixed block 94 and the retaining ring 97, and the retainer 95 can be reset through the retaining ring 97 and the spring 96. The side of the stop block 95 close to the moving block 92 is wedge-shaped, and the moving block 92 contacts the stop block 95 , so that the stop block 95 moves to both sides of the slide groove 6 .
[0024] The working process of the above scheme is as follows: the hatch 2 is opened to place the parts on the first loading plate 8 and the second loading plate 10. At this time, the electric cylinder 14 is started to push the push plate 15 to make the parts contact each other. At this time, the parts are fixed. The motor 11 is started to drive the threaded rod 13 to rotate so that the first loading plate 8 moves to the bottom of the processing device 3, which is convenient for the processing of the processing device 3. After the processing of the parts on the first loading plate 8 is completed, the motor 11 is started to make the first loading plate 8 continue to move. When the rotating rod 71 contacts the second loading plate 10, the rotating rod 71 drives the arc rod 73 to rotate, and the arc rod 73 clamps the second loading plate 10. At this time, the second loading plate 10 moves with the first loading plate 8, so that the second loading plate 10 is moved to the bottom of the processing device 3 to achieve the purpose of workpiece replacement. When the second loading plate 10 needs to be fixed and the first loading plate 8 needs to re-place the workpiece. Press the moving block 92 to make the moving block 92 contact with the stop block 95, and the stop block 95 contacts the slide groove 6. At this time, the rotating block 93 is rotated to make the moving block 92 contact each other. At this time, the second loading plate 10 is fixed, and the motor 11 is started to drive the first loading plate 8 to move. When the arc rod 73 no longer clamps the second loading plate 10, the rotating rod 71 is no longer stressed, and the torsion spring 74 drives the rotating rod 71 to rotate. The first loading plate 8 and the second loading plate 10 can be loaded separately through the adjustment device 9.
[0025] The above scheme has the following beneficial effects: the first loading plate 8 is driven to move by the motor 11 and the threaded rod 13 and other components, and the second loading plate 10 is clamped by the clamping device 7 so that the second loading plate 10 moves accordingly to achieve the purpose of replacement; the arc rod 73 is rotated by the rotating rod 71 to clamp the second loading plate 10 to prevent the arc rod 73 from damaging the second loading plate 10; the first loading platform is driven to move by the motor 11 to move the second loading platform, and the material cost is reduced by only one motor 11; the second loading plate 10 is fixed in position by the adjusting device 9, so that the second loading plate 10 can be fixed in the machine body 1 to prevent the second loading plate 10 from moving when the processing device 3 processes the second loading plate 10; the first loading plate 8 and the second loading plate 10 can be loaded separately by the adjusting device 9.
[0026] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
