However, due to the tightness of the floating clamping block, it is very difficult to install the floating clamping block. In addition, the floating clamping block has different models and sizes. Once the inappropriate one is selected, it will not only be unusable, but also reduce the work progress. At the same time, since most of the workpieces are special-shaped workpieces, it will be very difficult to use the clamping device, and there may be a risk of parts flying out during processing, endangering safe production. Utility Model Content

Once an inappropriate one is selected, it will not only be unusable but also reduce the work progress. At the same time, since most of the workpieces are special-shaped workpieces, it will be very difficult to use the clamping device, and there may be a risk of parts flying out during processing, endangering safe production.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a mechanical processing floating support automatic clamp, comprising: a base, a top outer surface of the base is fixedly connected with a positioning plate 1, and the base is provided with a notch on the side away from the positioning plate 1, and also includes: a slide groove, the inner surface of the slide groove is movably embedded with a sliding rod, the top outer surface of the sliding rod is fixedly connected with a fixing block, the outer surface of the fixing block is fixedly connected with a positioning plate 2, the outer surfaces of both sides of the fixing block are fixedly connected with a fixing rod 1, the outer surfaces of the two fixing rods 1 are movably sleeved with cams, the two cams are fixedly connected with a positioning rod 1 on the side away from the two fixing rods 1, the outer surfaces of the two positioning rods 1 are fixedly connected with a spring 1, and the two springs 1 are fixedly connected with a positioning rod 2 on the side away from the positioning rod 1, so that the movement of the clamping block can be achieved without installing a floating clamping block, thereby avoiding the need to install a floating clamping block.

[0006] As a preferred embodiment, a plurality of telescopic rods are movably embedded on a side of the positioning plate 2 away from the fixed block, and a spring 3 is movably sleeved on the outer surfaces of the plurality of telescopic rods, so that special-shaped workpieces can be clamped, and each clamping block fits with the surface of the part.

[0007] As a preferred embodiment, the outer surfaces of both sides of the fixed block are fixedly connected with fixed rods 2, the outer surfaces of the two fixed rods 2 are movably sleeved with gears, and the base is provided with working grooves on one side close to the two fixed rods 2, and the working grooves can limit the moving trajectory of the fixed rods 2.

[0008] As a preferred embodiment, the slide groove is provided on the bottom inner surface of the notch, and the two positioning rods are fixedly connected to the outer surface of the fixed block, and the slide groove can limit the movement trajectory of the slide rod.

[0009] As a preferred embodiment, the plurality of telescopic rods are evenly divided into three groups, and the outer surfaces of the three groups of telescopic rods are fixedly connected with clamping blocks, and the clamping blocks can clamp the parts.

[0010] As a preferred embodiment, a spring 2 is fixedly connected to one side of the two fixed rods 2 close to the inside of the two working grooves, and a side of the spring 2 away from the two fixed rods 2 is fixedly connected to the inner wall of the working groove, and the spring 2 provides power for the reverse movement of the fixed rod 2.

[0011] As a preferred embodiment, a plurality of tooth grooves are provided on one side of the two cams close to the two gears, and the tooth grooves can fit with the gears to prevent the gears from rotating.

[0012] As a preferred embodiment, the two gears are meshedly connected with a tooth plate on one side away from the plurality of tooth grooves, and the tooth plate can prevent the gears from moving horizontally when the gears are not rotating.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] The utility model, when using the automatic clamp for machining floating supports, first manually pull the two cams so that the tooth grooves on the two cams no longer position the two gears. When the two cams are pulled, the two cams drive the first positioning rod to rotate, and the spring first connected to the first positioning rod is connected to the second positioning rod, so that the spring one obtains elastic potential energy at this time, and then manually pulls the second positioning plate to move the second positioning plate to the side away from the first positioning plate on the base. When the second positioning plate moves, it drives the fixed block to move, and the fixed block drives the slide bar to move on the inner surface of the slide groove. At the same time, the fixed block drives the two gears to make a circular motion on the outer surfaces of the two tooth plates with the second fixed rod as the center, and the two second fixed rods will also move with the movement of the fixed block and compress the elastic force in the two working grooves. Spring 1 releases elastic potential energy to obtain elastic potential energy. When the positioning plate 1 and the positioning plate 2 are separated sufficiently, the workpiece is placed in the middle position of the positioning plate 1 and the positioning plate 2, and then the positioning plate 2 is no longer pulled. At this time, the two springs 2 release the elastic potential energy to push the two fixing rods 2 to move in the opposite direction, so that the two fixing rods 2 drive the fixing blocks to move in the opposite direction inside the notch. When the positioning plate 1 and the positioning plate 2 have clamped the parts, the two cams are released, and the two springs 1 release the elastic potential energy to drive the two cams to rotate in the opposite direction with the two fixing rods 1 as the center. Finally, the tooth grooves on the two cams clamp the two gears, so that the two gears no longer rotate. In this way, the movement of the clamping block can be achieved without installing a floating clamping block, thereby avoiding the need to install a floating clamping block and improving work efficiency.

[0015] The utility model, when the positioning plate one and the positioning plate two are clamping the workpiece, one of the clamping blocks will stop moving after hitting the part, while the clamping block that has not hit the part will continue to move forward due to the push of the positioning plate two, so the clamping block that hits the part first will push the telescopic rod to move in the opposite direction to the inside of the positioning plate two, and the spring three can continuously squeeze the clamping block so that the clamping block is always in contact with the surface of the part, so that the special-shaped workpiece can be clamped, and each clamping block is in contact with the surface of the part, thereby avoiding the flying out of the part and providing a guarantee for safe production.

[0024] like Figure 1-4 As shown, a plurality of telescopic rods 18 are movably embedded on one side of the positioning plate 2 7 away from the fixed block 6, and a spring 3 19 is movably sleeved on the outer surfaces of the plurality of telescopic rods 18, so that special-shaped workpieces can be clamped, and each clamping block 20 is in contact with the surface of the part, thereby preventing the part from flying out and providing a guarantee for safe production.

[0025] like Figure 1-4As shown, the outer surfaces of both sides of the fixed block 6 are fixedly connected with fixed rods 14, and the outer surfaces of the two fixed rods 14 are movably sleeved with gears 15. The base 1 is provided with working grooves 21 on one side close to the two fixed rods 14. The working grooves 21 can limit the moving trajectory of the fixed rods 14, thereby preventing the fixed rods 14 from driving the fixed block 6 off the track and affecting the use of the equipment.

[0026] like Figure 1-4 As shown, the slide groove 4 is opened on the bottom inner surface of the slot 3, and the two positioning rods 13 are fixedly connected to the outer surface of the fixed block 6. The slide groove 4 can limit the movement trajectory of the slide rod 5, further ensuring that the fixed block 6 will not derail and affect the use of the equipment.

[0027] like Figure 1-4 As shown, the multiple telescopic rods 18 are evenly divided into three groups, and the outer surfaces of the three groups of telescopic rods 18 are fixedly connected with clamping blocks 20. The clamping blocks 20 can clamp parts to facilitate processing of the parts.

[0028] like Figure 1-4 As shown, a spring 2 17 is fixedly connected to one side of the two fixing rods 14 close to the inside of the two working grooves 21, and a side of the spring 2 17 away from the two fixing rods 14 is fixedly connected to the inner wall of the working groove 21.

[0029] like Figure 1-4 As shown, a plurality of tooth grooves 10 are provided on one side of the two cams 9 close to the two gears 15 , and the tooth grooves 10 can fit with the gears 15 so that the gears 15 no longer rotate.

[0030] like Figure 1-4 As shown, the two gears 15 are meshedly connected with a tooth plate 16 on one side away from the plurality of tooth grooves 10. The tooth plate 16 can prevent the gear 15 from moving horizontally when the gear 15 does not rotate, so that the gear 15 is self-locking.

[0031] Working principle: When using the automatic fixture for machining floating supports, first manually pull the two cams 9 so that the tooth grooves 10 on the two cams 9 no longer position the two gears 15. When the two cams 9 are pulled, the two cams 9 drive the positioning rod 11 to rotate, and the spring 12 connected to the positioning rod 11 is connected to the positioning rod 2 13, so that the spring 12 obtains elastic potential energy at this time, and then manually pull the positioning plate 2 7 to move the positioning plate 2 7 to the side away from the positioning plate 2 on the base 1. When the positioning plate 2 7 moves, it will drive the fixed block 6 to move, and the fixed block 6 will The movable slide bar 5 moves on the inner surface of the slide groove 4, and at the same time, the fixed block 6 drives the two gears 15 to make a circular motion with the fixed rod 2 14 as the center on the outer surface of the two toothed plates 16, and the two fixed rods 2 14 will also move with the movement of the fixed block 6, and compress the springs 2 17 in the two working grooves 21, so that the springs 2 17 obtain elastic potential energy. When the positioning plate 1 2 and the positioning plate 2 7 are separated sufficiently, the workpiece is placed in the middle position between the positioning plate 1 2 and the positioning plate 2 7, and then the positioning plate 2 7 is no longer pulled. At this time, the two springs 2 17 release the elastic potential energy to push the two fixed rods 2 14 reverse movement, so that the two fixing rods 2 14 drive the fixing block 6 to move in the opposite direction inside the notch 3. When the positioning plate 1 2 and the positioning plate 2 7 have clamped the parts, the two cams 9 are released, and the two springs 12 release the elastic potential energy, driving the two cams 9 to rotate in the opposite direction with the two fixing rods 1 8 as the center. Finally, the tooth grooves 10 on the two cams 9 clamp the two gears 15, so that the two gears 15 no longer rotate. In this way, the movement of the clamping block 20 can be realized without installing the floating clamping block 20, avoiding the need to install the floating clamping block 20, thereby improving work efficiency. When the positioning plate 1 2 and the positioning plate 2 7 are clamping the workpiece, one of the clamping blocks 20 will stop moving after hitting the part, while the clamping block 20 that has not hit the part will continue to move forward due to the push of the positioning plate 2 7, so the clamping block 20 that hits the part first will push the telescopic rod 18 to move in the opposite direction to the inside of the positioning plate 2 7, and the spring 3 19 can keep squeezing the clamping block 20 so that the clamping block 20 is always in contact with the surface of the part, so that special-shaped workpieces can be clamped, and each clamping block 20 is in contact with the surface of the part, avoiding the flying out of the part, providing a guarantee for safe production.
