Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] Referring to Figures 1-4 , a double-positioning precision machining horizontal boring machine includes a workbench 1. Two installation grooves 7 are opened inside the workbench 1.

The top of the workbench 1 and on both sides of the extrusion pieces 5 are all slidably connected with clamping pieces 6. On the top of the workbench 1 and on one side of the clamping pieces 6 are all provided with fixing pieces 2. The two ends inside the fixing pieces 2 are all threadedly connected with first fixing bolts 3. The fixing pieces 2 and the workbench 1 are connected by the first fixing bolts 3. Clamping grooves one are opened inside the clamping pieces 6. Clamping grooves two that are matched with the clamping grooves one are equidistantly opened inside the fixing pieces 2. By arranging a plurality of clamping pieces 6 and four fixing pieces 2 on the workbench 1, clamping operations on a plurality of small workpieces can be realized, so as to meet the production requirements of a large number of small workpieces. Along with the movement of the sleeves 13, the extrusion pieces 5 can be used to move downward to extrude the clamping pieces 6 on both sides of them, so that the clamping pieces 6 approach the corresponding fixing pieces 2 respectively, so that a plurality of small workpieces can be stably clamped between the clamping grooves one and the clamping grooves two. By using the first fixing bolts 3, the fixing pieces 2 can be detached from the workbench 1. At the same time, the clamping pieces 6 are also of a detachable design. In this way, the staff can replace the fixing pieces 2 and the clamping pieces 6 with corresponding shapes according to the shape of the workpiece to improve the applicability of the device.

[0030] Referring toFigure 4 , a transmission mechanism is arranged inside the installation groove 7. The transmission mechanism includes a screw rod 10 rotatably connected to the inner wall of the installation groove 7 and located below the sleeve 13. Gears 9 are fixedly connected to the outer sides of the screw rod 10. A rack 8 is arranged on the inner wall of the workbench 1. The gears 9 are all meshed with the rack 8. Through the movement of the rack 8, the rotation of the gears 9 can be driven, and at the same time, the rotation of the screw rod 10 can be driven, so as to achieve the purpose of the up and down movement of the sleeve 13, and thus the transmission of power can be realized.

[0031] Refer to Figure 4 , reset mechanisms are arranged on both sides of the installation groove 7. The reset mechanisms include fixing grooves 14 opened inside the workbench 1 and located on both sides of the installation groove 7. Fixing rods 15 are fixedly connected to the interiors of the fixing grooves 14. Sliders 16 are slidably connected to the outer sides of the fixing rods 15. Springs 17 are sleeved on the outer sides of the fixing rods 15 and on one side of the sliders 16. When the pressing member 5 presses the clamping members 6 on both sides thereof, at this time, the clamping members 6 are pressed and move towards the fixing member 2. At this time, the springs 17 are compressed to generate a locking phenomenon, so as to realize the clamping operation. When the pressing member 5 no longer presses the clamping members 6, through the elastic force of the springs 17, the sliders 16 can be pushed to move on the fixing rods 15, and thus the corresponding clamping members 6 can be driven to reset.

[0032] Refer to Figure 3 , a replacement mechanism is arranged at the bottom of the clamping member 6. The replacement mechanism includes a slot opened inside the clamping member 6 and used in cooperation with the slider 16. Card holes are opened on both sides of the slider 16. Fixing bolts II 18 are arranged on both sides of the clamping member 6. The slider 16 and the clamping member 6 are connected through the fixing bolts II 18. Through the arrangement of the fixing bolts II 18, the slider 16 can be installed in the slot inside the clamping member 6. In this way, it is convenient to disassemble the clamping member 6 and the slider 16, so as to replace the clamping member 6 with a corresponding shape according to the shape of the workpiece.

The piston rods of the electric telescopic rods 4 all extend into the interior of the installation groove 7 and are fixedly connected to the corresponding racks 8. Through the telescopic movement of the piston rods of the electric telescopic rods 4, the movement of the racks 8 can be driven.

[0034] Refer to Figure 4 , limiting grooves 11 are equidistantly opened on both sides of the inner wall of the installation groove 7. Limiting blocks 12 are slidably connected to the interiors of the limiting grooves 11. The two limiting blocks 12 are respectively fixedly connected to both sides of the sleeve 13.

[0035] Refer toFigure 4 , a support groove 20 is formed inside the workbench 1 and on one side of the rack 8. A support block 19 is fixedly connected to the side of the rack 8 close to the support groove 20. The support block 19 is slidably installed on the inner wall of the support groove 20. By using the cooperation of the support block 19 and the support groove 20, the rack 8 can be moved according to the orientation of the support groove 20, which can play a certain supporting role for the rack 8.

[0036] Working principle: First, place multiple small workpieces on the workbench 1 and between the first clamping groove and the second clamping groove. By arranging multiple clamping members 6 and four fixing members 2 on the workbench 1, the clamping operation of multiple small workpieces can be realized, so as to meet the mass production requirements of small workpieces. Subsequently, start the electric telescopic rod 4. Through the movement of the rack 8, the rotation of the gear 9 can be driven. Along with the movement of the sleeve 13, the downward movement of the pressing member 5 can be used to press the clamping members 6 on both sides of it, so that the clamping members 6 approach the corresponding fixing members 2 respectively, so that multiple small workpieces can be stably clamped between the first clamping groove and the second clamping groove. When the pressing member 5 presses the clamping members 6 on both sides of it, at this time, the clamping members 6 are pressed and move towards the fixing member 2. At this time, the spring 17 is compressed and a locking phenomenon occurs, so as to realize the clamping operation. When the pressing member 5 no longer presses the clamping members 6, through the elastic force of the spring 17, the slider 16 can be pushed to move on the fixed rod 15, and then the corresponding clamping member 6 can be driven to reset;

[0037] By using the fixing bolt 1 3, the fixing member 2 can be disassembled from the workbench 1. At the same time, through the setting of the fixing bolt 2 18, the slider 16 can be installed in the slot in the clamping member 6. This method is convenient for disassembling the clamping member 6 and the slider 16. In this way, the staff can replace the fixing member 2 and the clamping member 6 with corresponding shapes according to the shape of the workpiece to improve the applicability of the device. Through the cooperation of the limiting groove 11 and the limiting block 12, an important limiting effect can be exerted on the sleeve 13, avoiding the self-rotation phenomenon of the sleeve 13 during the lifting process to ensure the normal operation of the sleeve 13.
