DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to clearly and completely describe the purpose and technical solutions of the present utility model, and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0020] Embodiment 1

[0021] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: an automatic positioning mechanism for a metal processing table, including a machine body 1 and two clamping blocks 15. Two sliders 2 are slidably connected to the top of the machine body 1. The machine body 1 plays a limiting role on the sliders 2, enabling the sliders 2 to slide smoothly. A lead screw 5 is rotatably connected to the top of the slider 2. A nut sleeve 6 is threadedly connected to the outside of the lead screw 5. Two connecting blocks 14 are fixedly connected to the separated sides of the two clamping blocks 15, and the connecting blocks 14 are inserted into the inside of the nut sleeve 6.

[0022] By moving the nut sleeve 6 up and down, the nut sleeve 6 can drive the clamping block 15 to move up and down through the connecting block 14, so that the clamping block 15 can clamp and position metal parts at different heights.

[0023] Embodiment 2

[0024] On the basis of Embodiment 1, in order to conveniently move the nut sleeve 6, support rods 3 are fixedly connected to the front and rear sides of the top of the slider 2. A support frame 4 is fixedly connected to the top of the support rod 3. The middle of the support frame 4 is rotatably connected to the upper side of the lead screw 5. The support frame 4 plays a limiting role on the lead screw 5, enabling the lead screw 5 to rotate smoothly. The nut sleeve 6 is slidably connected to the outside of the support rod 3. The support rod 3 plays a limiting role on the nut sleeve 6, so that the nut sleeve 6 will not shift when moving up and down.

[0025] By rotating the lead screw 5, the lead screw 5 can drive the nut sleeve 6 to slide up and down on the outside of the support rod 3, so that the nut sleeve 6 can smoothly drive the clamping block 15 to move up and down through the connecting block 14, so that the clamping block 15 can clamp metal parts at different heights.

[0026] Embodiment 3

[0027] On the basis of Embodiment 2, in order to facilitate the replacement of the clamping block 15, a placement groove 13 is formed in the upper side of the wire sleeve 6. Arc-shaped grooves are formed in the left and right sides of the placement groove 13. Two installation grooves 7 are formed in the interior of the wire sleeve 6. A pull rope 8 is slidably connected to the interior of the installation groove 7. The installation groove 7 positions the pull rope 8, such that the pull rope 8 will not shift during movement. One end of the pull rope 8 is fixedly connected to a pull ring 12. The exterior of the pull ring 12 is slidably connected to the interior of the placement groove 13. The placement groove 13 positions the pull ring 12, such that the pull ring 12 will not affect the normal movement of the wire sleeve 6. Moreover, due to the design of the arc-shaped grooves, workers can conveniently pull the pull ring 12. The other end of the pull rope 8 is fixedly connected to a limit block 9. The exterior of the limit block 9 is slidably connected to the interior of the installation groove 7. The installation groove 7 positions the limit block 9, such that the limit block 9 will not shift during movement. The end of the limit block 9 away from the pull rope 8 is fixedly connected to a clamping block 10. A rubber block 19 is sleeved on the exterior of the pull rope 8. One end of the rubber block 19 is fixedly connected to the inner wall of the installation groove 7. The other end of the rubber block 19 is fixedly connected to the end of the limit block 9 away from the clamping block 10. The clamping block 10 passes through the connecting block 14 and is engaged with the interior of the card slot 11.

[0028] When it is necessary to replace the clamping block 15, by pulling the pull ring 12 upward, the pull ring 12 can drive the pull rope 8 to move upward. Furthermore, the pull rope 8 can pull the limit block 9 to squeeze the rubber block 19 to deform. Thus, the limit block 9 can drive the clamping block 10 to disengage from the interior of the card slot 11. At this time, by pulling the clamping block 15, the connecting block 14 can be disengaged from the interior of the wire sleeve 6. Furthermore, the clamping block 15 can be conveniently disassembled. Then, the clamping block 15 of the required model is fitted to the wire sleeve 6, and the connecting block 14 can be inserted into the interior of the wire sleeve 6. At this time, the pull ring 12 is released, such that the rubber block 19 can perform a reset movement. Furthermore, the rubber block 19 can push the limit block 9 to move in the direction close to the card slot 11. Furthermore, the limit block 9 can push the clamping block 10 to pass through the connecting block 14 and be engaged with the interior of the card slot 11, such that the clamping block 15 can be conveniently installed.

[0029] Embodiment 4

[0030] On the basis of Embodiment 3, in order to reduce damage during the clamping and positioning of metal parts, a plurality of insertion slots 16 are formed in the right side of the clamping block 15. The plurality of insertion slots 16 are evenly distributed. An insertion block 17 is inserted into the interior of the insertion slot 16. A rubber pad 18 is fixedly connected to the right end of the insertion block 17, such that the force on the rubber pad 18 is relatively uniform. Furthermore, the installation of the rubber pad 18 is relatively stable. A plurality of convex blocks are arranged on the exterior of the insertion block 17. The convex blocks are in contact with the inner wall of the insertion slot 16, thereby increasing the friction between the insertion block 17 and the insertion slot 16. Furthermore, the installation of the rubber pad 18 is more stable.

[0031] When the rubber pad 18 needs to be installed, the insertion block 17 is inserted into the slot 16 at the corresponding position. During this process, the bump on the outside of the insertion block 17 is deformed by the extrusion of the slot 16. After the insertion block 17 is inserted, the slot 16 makes a reset movement, so that the frictional force between the insertion block 17 and the slot 16 is increased, and thus the rubber pad 18 is installed more stably.

[0032] In actual use, by pulling up the pull ring 12, the pull ring 12 can drive the pull rope 8 to move upward, and then the pull rope 8 can pull the limit block 9 to squeeze the rubber block 19 to deform, so that the limit block 9 can drive the clamping block 10 to disengage from the inside of the card slot 11. At this time, by pulling the clamping block 15, the connecting block 14 can be disengaged from the inside of the wire sleeve 6, and then the clamping block 15 can be conveniently disassembled. Then, the clamping block 15 of the required model is fitted to the wire sleeve 6, and the connecting block 14 can be inserted into the inside of the wire sleeve 6. At this time, the pull ring 12 is released, so that the rubber block 19 can make a reset movement, and then the rubber block 19 can push the limit block 9 to move towards the direction close to the card slot 11, and then the limit block 9 can push the clamping block 10 to penetrate through the connecting block 14 and engage with the inside of the card slot 11, so that the clamping block 15 can be conveniently installed, and the clamping block 15 can clamp and position metal parts of different shapes. At this time, by rotating the lead screw 5, the lead screw 5 can drive the wire sleeve 6 to slide up and down outside the support rod 3, so that the wire sleeve 6 can stably drive the clamping block 15 to move up and down through the connecting block 14, and then the clamping block 15 can clamp and position metal parts of different heights, so that the use flexibility of the mechanism is relatively high, and the use economy is relatively good.
