Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Refer to Figure 1 - Fig.10 , a multifunctional lifting horizontal lathe, including a lathe body 1, and two fixed plates 2 are fixedly connected to the inner bottom of the lathe body 1.

Workpieces to be processed are placed in the placement frame 7.

[0023] Through grooves 10 are opened on the inner side walls of the two grooves 3 away from each other, the side walls of the two cross bars 6 away from each other respectively penetrate through the inner walls of the two through grooves 10, gears 11 are fixedly connected to the side walls of the two cross bars 6 away from each other, and toothed plates 12 are fixedly connected to the side walls of the fixed plates 2 above the gears 11. The gears 11 are meshed with the toothed plates 12 during the upward movement (as Figure 4 shown).

[0024] The lifting plate 4 is provided with a limiting mechanism for limiting the position of the cross bar 6, and the limiting mechanism includes a connecting plate 13 (such as Figure 6 As shown, the side wall of the connecting plate 13 away from the lifting plate 4 is fixedly connected to a U-shaped plate 14, and the top and bottom of the U-shaped plate 14 are fixedly connected to a rectangular rod 15 (as shown in FIG. Figure 5 As shown), the side wall of the rectangular rod 15 is slidably connected to two first L-shaped rods 16, and the side walls of the two first L-shaped rods 16 close to each other are fixedly connected to an arc-shaped friction plate 17, and the inner wall of the arc-shaped friction plate 17 is in contact with the side wall of the cross bar 6.

[0025] Two fixed frames 8 are fixedly connected to the bottom of the placement frame 7, and the inner walls of the two fixed frames 8 are sealed and fixedly connected with elastic plates 9. A hard tube 25 is passed through and fixedly connected to the side wall of the cross bar 6. The side wall of the connecting plate 13 is fixedly connected to a rotating joint 24 through a second L-shaped rod 23. One end of the hard tube 25 is fixedly connected to one end of the rotating joint 24, and the other end of the hard tube 25 is connected to the inner wall of the fixed frame 8.

[0026] An oil pump frame 26 is fixedly connected to the upper end of the lifting plate 4, and a first plate 27 is sealingly and slidably connected to the inner wall of the oil pump frame 26. The side wall of the first plate 27 is elastically connected to the inner wall of the oil pump frame 26 through a plurality of second springs 28. The inner wall of the oil pump frame 26 is connected to an end of the rotary joint 24 away from the hard tube 25 through a hose 29.

[0027] The side wall of the first plate 27 away from the second spring 28 is fixedly connected to a third wedge plate 31 through a second rod 30, and the inner wall of the groove 3 is fixedly connected to a fourth wedge plate 32 (such as Fig. 9 as shown).

[0028] After the workpiece to be processed is placed in the placement frame 7, the four hydraulic cylinders 5 are adjusted to extend to drive the workpiece to move up to the processing position in the lathe body 1. Before the workpiece moves up to the processing position in the lathe body 1, the side wall of the third wedge plate 31 and the side wall of the fourth wedge plate 32 are in contact with each other. Under the extrusion of the fourth wedge plate 32, the third wedge plate 31 drives the first plate 27 to move through the second rod 30, compresses the multiple second springs 28, and squeezes the hydraulic oil in the oil pump frame 26 into the fixed frame 8 through the hose 29, the rotary joint 24 and the hard tube 25, driving the elastic plate 9 to deform and clamp the workpiece to avoid the movement of the workpiece during subsequent processing, and there is no need to set up other clamping equipment.

[0029] The side wall of the L-shaped plate 14 is slidably connected to a first rod 19, and the side wall of the first rod 19 away from the rectangular rod 15 is fixedly connected to a first wedge plate 18. The side wall of the first wedge plate 18 is elastically connected to the side wall of the L-shaped plate 14 through a plurality of first springs 21, and the side wall of the first rod 19 away from the first wedge plate 18 is rotatably connected to the side walls of the two first L-shaped rods 16 respectively through two rotating plates 20, and a second wedge plate 22 corresponding to the first wedge plate 18 is fixedly connected to the upper side wall of the fixed plate 2.

[0030] It should be noted that before the side wall of the first wedge plate 18 is fitted with the side wall of the second wedge plate 22, the side wall of the third wedge plate 31 has been fitted with the side wall of the fourth wedge plate 32. Then, when the lifting plate 4 moves up to make the side wall of the first wedge plate 18 fit with the side wall of the second wedge plate 22, the gear 11 is meshed with the toothed plate 12, and the first wedge plate 18 is squeezed by the second wedge plate 22, and the first wedge plate 18 moves toward the direction close to the L-shaped plate 14. At this time, the first rod 19 drives the two first L-shaped rods 16 away from each other through the two rotating plates 20, so that the two arc friction plates 17 are respectively separated from the side walls of the cross bar 6 to avoid hindering the rotation of the cross bar 6 when the subsequent gear 11 is meshed with the toothed plate 12. When there is no wall on the side of the first wedge plate 18 and the side wall of the second wedge plate 22, the two arc friction plates 17 are respectively fitted with the side walls of the cross bar 6 to limit the position of the cross bar 6 and ensure the stability of the workpiece placement.

[0031] As the lifting plate 4 moves upward, the gear 11, under the action of the toothed plate 12, will drive the placement frame 7 to rotate through the cross bar 6, and drive the workpiece to rotate, so that the workpiece is rotated at different angles for processing. During processing, it is only necessary to place different tools at different heights to achieve automated processing of different positions of the workpiece (it should be noted that the placement of tools at different heights and the automated processing of the workpiece by the tools are both existing technologies and will not be elaborated here). There is no need to re-change the position of the workpiece for processing, which avoids the need to re-install the workpiece when other positions of the workpiece need to be processed in the prior art, and the need to adjust the position of the workpiece to the initial position during the installation process, which increases the technical difficulty of the workpiece processing process.

[0032] A buffer mechanism is provided in the groove 3, and the buffer mechanism includes two buffer frames 33 fixedly connected to the bottom of the groove 3. The inner walls of the two buffer frames 33 are sealed and slidably connected with buffer rods 34. The upper ends of the two buffer rods 34 are both in contact with the lower ends of their corresponding lifting plates 4, and the lower ends of the buffer rods 34 are elastically connected to the inner bottom of the buffer frame 33 through a third spring 35.

[0033] The upper end of the lifting plate 4 is fixedly connected to a liquid storage frame 36 , the inner wall of the liquid storage frame 36 is sealed and slidably connected to a second plate 37 , the inner wall of the liquid storage frame 36 is connected to the lower inner walls of the two buffer frames 33 through a connecting pipe 38 , and non-Newtonian liquid is provided in the liquid storage frame 36 .

[0034] The characteristic of non-Newtonian fluids is that there is a nonlinear relationship between shear stress and shear strain rate, that is, the viscosity is changing. When subjected to external impact, non-Newtonian fluids will become as hard as solids and show strong resistance; and when the external impact disappears, they will turn into liquids again. Then, non-Newtonian liquids will become more viscous when subjected to impact, thereby providing additional resistance to slow down the impact force and having a buffering effect. The upper end of the lifting plate 4 is rotatably connected to a lead screw 39 through a bracket, and the side wall of the lead screw 39 is threadedly connected to a third plate 40, and the side wall of the third plate 40 is fixedly connected to the side wall of the second plate 37 through a plurality of connecting rods.

[0035] A threaded cylinder 41 is rotatably connected to the side wall of the lifting plate 4, a rifle rod 42 is fixedly connected to the top of the groove 3, the side wall of the rifle rod 42 is threadedly connected to the inner wall of the threaded cylinder 41, a first bevel gear 43 is fixedly connected to the side wall of the threaded cylinder 41, and a second bevel gear 44 is fixedly connected to the side wall of the lead screw 39 away from the liquid storage frame 36, and the first bevel gear 43 and the second bevel gear 44 are meshed with each other.

[0036] When the lifting plate 4 moves upward slowly, under the action of the rifle rod 42, the threaded cylinder 41 rotates forward, and then drives the lead screw 39 to rotate forward through the first bevel gear 43 and the second bevel gear 44, so that the third plate 40 drives the second plate 37 to move close to the inner wall of the liquid storage frame 36 through multiple connecting rods, and squeezes the non-Newtonian liquid in the liquid storage frame 36 into the two buffer frames 33 through the connecting pipe 38, driving the two buffer rods 34 to move upward, so that the upper ends of the two buffer rods 34 are always in contact with the lower end of the lifting plate 4. Then, when the workpiece is subjected to vibration during the subsequent processing, the vibration can be transmitted to the non-Newtonian liquid, and then the vibration is buffered to protect the workpiece; When the lifting plate 4 moves slowly downward, under the action of the rifle rod 42, the threaded cylinder 41 rotates in the opposite direction, driving the lead screw 39 to rotate in the opposite direction, so that the third plate 40 drives the second plate 37 to move away from the inner wall of the liquid storage frame 36 through multiple connecting rods. At this time, the liquid storage frame 36 absorbs non-Newtonian liquid from the two buffer frames 33 through the connecting tube 38, driving the two buffer rods 34 to move downward, so that the upper ends of the two buffer rods 34 are always in contact with the lower end of the lifting plate 4.

[0037] If the hydraulic cylinder 5 fails during the workpiece processing and the lifting plate 4 moves down quickly, the threaded barrel 41 will rotate in the opposite direction quickly, driving the screw 39 to rotate in the opposite direction quickly, so that the third plate 40 drives the second plate 37 to move quickly away from the inner wall of the liquid storage frame 36 through multiple connecting rods. At this time, the non-Newtonian liquid in the liquid storage frame 36 will be subjected to a large suction force, so that the non-Newtonian liquid will become as hard as a solid, showing a strong resistance, making the second plate 37 unable to move, thereby hindering the rotation of the threaded barrel 41, making it impossible for the lifting plate 4 to move down quickly, avoiding damage to the lathe body 1 or safety accidents.

[0038] When the horizontal lathe is in use, the workpiece is first placed in the placement frame 7, and then the four hydraulic cylinders 5 are adjusted to extend to drive the workpiece to move up to the processing position in the lathe body 1. Before the workpiece moves up to the processing position in the lathe body 1, the side wall of the third wedge plate 31 and the side wall of the fourth wedge plate 32 are in contact with each other. Under the pressure of the fourth wedge plate 32, the third wedge plate 31 drives the first plate 27 to move through the second rod 30, compresses the multiple second springs 28, and squeezes the hydraulic oil in the oil pump frame 26 into the fixed frame 8 through the hose 29, the rotary joint 24 and the hard tube 25, drives the elastic plate 9 to deform, clamps the workpiece, avoids the movement of the workpiece during subsequent processing, and does not need to set up other clamping equipment; When the lifting plate 4 moves upward slowly, under the action of the rifle rod 42, the threaded cylinder 41 rotates forward, and then drives the lead screw 39 to rotate forward through the first bevel gear 43 and the second bevel gear 44, so that the third plate 40 drives the second plate 37 to move close to the inner wall of the liquid storage frame 36 through multiple connecting rods, and squeezes the non-Newtonian liquid in the liquid storage frame 36 into the two buffer frames 33 through the connecting pipe 38, driving the two buffer rods 34 to move upward, so that the upper ends of the two buffer rods 34 are always in contact with the lower end of the lifting plate 4. When the workpiece is subjected to vibration during the subsequent processing, the vibration can be transmitted to the non-Newtonian liquid, and then the vibration is buffered to protect the workpiece; When it is necessary to process other positions of the workpiece, the four hydraulic cylinders 5 are further adjusted to extend. When the lifting plate 4 moves up so that the side wall of the first wedge plate 18 fits with the side wall of the second wedge plate 22, the gear 11 is meshed with the toothed plate 12, and the first wedge plate 18 is squeezed by the second wedge plate 22, and the first wedge plate 18 moves toward the direction close to the L-shaped plate 14. At this time, the first rod 19 drives the two first L-shaped rods 16 away from each other through the two rotating plates 20, so that the two arc friction plates 17 are separated from the side walls of the cross bar 6 respectively, so as to avoid the subsequent gear 11 and the toothed plate 12 from meshing, which will hinder the rotation of the cross bar 6. When there is no wall on the side of the first wedge plate 18 and the side wall of the second wedge plate 22, the two arc friction plates 17 are respectively fitted with the side walls of the cross bar 6, and the position of the cross bar 6 is limited to ensure the stability of the workpiece placement. As the lifting plate 4 moves upward, the gear 11, under the action of the toothed plate 12, drives the placement frame 7 to rotate through the crossbar 6, and drives the workpiece to rotate, so that the workpiece is rotated at different angles for processing. During processing, it is only necessary to place different tools at different heights to realize automatic processing of different positions of the workpiece, and there is no need to re-change the position of the workpiece for processing, which avoids the need to re-install the position of the workpiece when processing other positions of the workpiece in the prior art, and the need to adjust the position of the workpiece to the initial position during the installation process, which increases the technical difficulty in the workpiece processing process; When the lifting plate 4 moves slowly downward, under the action of the rifle rod 42, the threaded cylinder 41 rotates in the opposite direction, driving the lead screw 39 to rotate in the opposite direction, so that the third plate 40 drives the second plate 37 to move away from the inner wall of the liquid storage frame 36 through multiple connecting rods. At this time, the liquid storage frame 36 absorbs non-Newtonian liquid from the two buffer frames 33 through the connecting tube 38, driving the two buffer rods 34 to move downward, so that the upper ends of the two buffer rods 34 are always in contact with the lower end of the lifting plate 4.

[0039] If the hydraulic cylinder 5 fails during the workpiece processing and the lifting plate 4 moves down quickly, the threaded barrel 41 will rotate in the opposite direction quickly, driving the screw 39 to rotate in the opposite direction quickly, so that the third plate 40 drives the second plate 37 to move quickly away from the inner wall of the liquid storage frame 36 through multiple connecting rods. At this time, the non-Newtonian liquid in the liquid storage frame 36 will be subjected to a large suction force, so that the non-Newtonian liquid will become as hard as a solid, showing a strong resistance, making the second plate 37 unable to move, thereby hindering the rotation of the threaded barrel 41, making it impossible for the lifting plate 4 to move down quickly, avoiding damage to the lathe body 1 or safety accidents.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
