Description

B1-5130 NUMERICALLY CONTROLLED MACHINE TOOL LU101685
CAPABLE OF PREVENTING OFFSET OF WORKPIECE Technical field The present invention relates to the field of mechanical equipment, in particular to a numerically controlled machine tool capable of preventing offset of a workpiece. Technical background With the technological development of the machinery industry, the production efficiency of numerically controlled machine tools is getting higher and higher. When a workpiece is processed, various parts can be processed by different processing tools, etc, and the numerically controlled machine tools can reduce the used manual operation and facilitate long-term work. Existing numerically controlled machine tools cannot adjust the fixed height of the | workpiece when the workpiece is fixed to process. Without proper height, it is | impossible to observe the morphological process of processing the workpiece so that the error cannot be corrected in time, and the position of the workpiece cannot | be adjusted at will, which is prone to shaking or offset, resulting in low processing | accuracy and even scrap of the workpiece. Summary of the invention | in order to solve the disadvantages existing in the prior art that the height of the { workpiece and the position of the workpiece on the machine tool cannot be | adjusted, an objective of the present invention is to propose a numerically | controlled machine tool capable of preventing the offset of the workpiece. | | In order to achieve the above objective, the present invention adopts the following | technical solution: | ee —— — —
; A numerically controlled machine tool capable of preventing offset of a workpieceLU101685 comprising a slide rail, a slide seat is slidably mounted on the slide rail; a gas . pressure platform is fixedly mounted on the slide seat; a plurality of gas holes are | opened in the gas pressure platform; each of the gas holes is slidably mounted with ) 5 a gas rod therein; the lower end of each of the gas rods is fixedly mounted with a , piston; the upper ends of the plurality of gas rods are commonly fixedly mounted with a fixed platform; a plurality of fixed clamp seats are mounted on the fixed | platform; an arc-shaped clamp slot is provided on each of the fixed clamp seats; a segment of the workpiece is placed in the arc-shaped clamp slot to fix; and the fixed platform and the slide seat are commonly mounted with a clamping mechanism thereon.
Preferably, the clamping mechanism comprises a plurality of fixed pneumatic screwdrivers symmetrically fixedly mounted on the slide seat; the output end of © 15 each of the fixed pneumatic screwdrivers is mounted with a threaded cap; a | threaded rod is threadedly mounted in each of the threaded caps; the upper end of . each of the threaded rods is slidably inserted in the fixed platform and extends ; above the fixed platform; the upper end of each of the threaded rods is welded with a limiting post; the upper ends of a plurality of limiting posts are commonly mounted . 20 with a pressure plate; and the bottom wall of the pressure plate is mounted with a , plurality of pressure blocks, and the plurality of pressure blocks are in one-to-one ‘ correspondence with the plurality of fixed clamp seats.
When the fixed pneumatic screwdriver is operating, the fixed pneumatic | 25 screwdriver drives the threaded cap to rotate, so that the threaded rod moves up . and down, and the pressure plate is moved up and down through the limiting post, | which causes the pressure block to move up and down.
That is, it can fix different diameters of thin and thick workpieces to process.
Preferably, a plurality of first threaded holes are opened on one side of the fixed | | platform; the fixed clamp seat is mounted on the upper surface of the fixed platform : by locking screws and the first threaded holes; a plurality of second threaded holes are opened on the lower bottom surface of the pressure plate, and the plurality of | second threaded holes are in one-to-one correspondence with the plurality of firstthreaded holes; and the pressure block is fixed on the lower bottom surface of thæU101685 ; pressure plate by screws and the second threaded holes.
; The fixed clamp seat can be arbitrarily mounted on the surface of the fixed platform ; 5 having the first threaded holes through disassembly and assembly of screws, so that the position and number of the fixed clamp seat can each be adjusted. Preferably, a first gas nozzle is mounted on the slide seat; a first control gas pipe is , embedded in the slide seat, and the first control gas pipe is connected to the first . 10 gas nozzle; a plurality of first branch pipes are connected to the first control gas , pipe; a plurality of synchronous gas pipes are embedded in the gas pressure . platform, and the plurality of synchronous gas pipes are in communication with a ; plurality of gas holes, respectively; and the plurality of first branch pipes are in communication with the plurality of synchronous gas pipes, respectively.
| 15 ; The first gas nozzle is connected to a gas pressure controller of the machine tool. | When the gas pressure controller changes the gas pressure of the first gas nozzle, , the gas pressure in the gas hole increases or decreases, the piston and the gas rod | rise or fall, and the fixed platform rises or falls with the plurality of gas rods, so that , 20 different heights can be adjusted as needed when the workpiece is processed.
| Preferably, a second gas nozzle is mounted on the slide seat; a second control gas ; pipe is embedded in the slide seat, and the second control gas pipe is connected to . the second gas nozzle; a plurality of second branch pipes are connected to the ; 25 second control gas pipe; and the plurality of second branch pipes are connected to , the plurality of fixed pneumatic screwdrivers, respectively.
Preferably, a cylinder is fixedly mounted at the lower end of the slide seat; the ; upper end of the slide rail is opened with a slide groove, two slide rods are fixedly © 30 mounted on the slide rail, and the cylinder is slidably sleeved on the two slide rods; ; the cylinder is slidably mounted in the slide groove; a third gas nozzle is mounted | on the slide seat; a third control gas pipe is embedded in the slide seat; and two ends of the third control gas pipe are connected to the cylinder and the third gas nozzle, respectively.
| 4 LU101685 , The third gas nozzle is connected to the gas pressure controller of the machine tool. | When the gas pressure controller changes the gas pressure of the third gas nozzle, ; the cylinder slides on the two slide rods, so that the slide seat slides on the slide rail | 5 without manually adjusting the position of the slide seat.
: The upper surface of the slide rail is symmetrically opened with two rolling grooves ; thereon, each rolling groove is rotably mounted with a plurality of rollers at an equal ; distance therein, and the upper ends of the plurality of rollers abut against the lower ; 10 bottom wall of the slide seat.
| The roller rolls in the sliding process of the slide seat, which reduces the friction | force between the slide seat and the slide rail, and can reduce the load of the two ; slide rods.
; The present invention has the following beneficial effects: | 1. The second gas nozzle, the second control gas pipe, the plurality of second ) branch pipes and the plurality of fixed pneumatic screwdrivers are communicated, ; 20 and the fixed pneumatic screwdriver is controlled by the gas pressure to rotate | forwardly or reversely so that the pressure plate moves up or down. Therefore, the ; pressure block is far away from the fixed clamp seat, so that the workpiece can be | easily placed in the arc-shaped clamp slot on the fixed clamp seat or the pressure | block clamps the workpiece in the arc-shaped clamp slot on the fixed clamp seat ; 25 without manual loosening or clamping, reducing operation workload. Moreover, the ; pressure plate is locked by the screw cap, so that the pressure block locks the | workpiece to increase the fixed strength.
| 2. The plurality of fixed clamp seats and the plurality of pressure blocks can fix a | 30 plurality of workpieces for processing at the same time, and the plurality of fixed | clamp seats can change the number and position of fixed clamp seats by | disassembly and assembly of the screws and the first threaded holes. Meanwhile, | the pressure blocks match the number and position of the fixed clamp seats by
; 5 : disassembly and assembly of the screws and the second threaded holes, therebyu101685 ; increasing the flexibility of the device.
; 3. The first gas nozzle, the first control gas pipe, the plurality of first branch pipes, ; 5 the plurality of synchronous gas pipes, and the plurality of gas holes are | communicated, the change of the gas pressure in the plurality of gas holes can be | controlled, and the piston and the gas rod in the gas holes can be controlled to ; move up and down. That is, the fixed platform can be caused to move up and down, | and the fixed height of the workpiece can be changed, increasing the flexibility of | 10 processing and fixing the workpiece.
| 4. The slide rail and the slide seat slide in the slide groove by the cylinder, and a ; plurality of rollers are symmetrically rotably embedded on two sides of the slide rail. | When the slide seat is driven by the cylinder to slide on the slide rail, a roller closely ; 15 attached to the bottom surface of the slide seat rotates, the slide friction force | between the slide seat and the slide rail is reduced, and the gravity load of the two | slide rods is reduced, increasing the service life of the slide rods.
| In summary, the present invention controls the fixed platform to fix the height of the | 20 workpiece by connecting a first gas nozzle, and controls a pneumatic screwdriver ; to clamp the workpiece by connecting a second gas nozzle. The detachable ; installation of the fixed clamp seat and the pressure block increases the flexibility of ; the device to fix the workpiece and the applicability.

The upper end of each threaded rod | 15 is slidably inserted in the fixed platform 10 and extends above the fixed platform | 10. The upper end of each threaded rod 15 is welded with a limiting post 12. The | upper ends of a plurality of limiting posts 12 are commonly mounted with a | pressure plate 11. The bottom wall of the pressure plate 11 is mounted with a | 10 plurality of pressure blocks 13, and the plurality of pressure blocks 13 are in | one-to-one correspondence with the plurality of fixed clamp seats 14. | When the fixed pneumatic screwdriver 18 is operating, the fixed pneumatic | screwdriver 18 drives the threaded cap 16 to rotate, so that the threaded rod 15 ; 15 moves up and down, and the pressure plate 11 is moved up and down through the | | limiting post 12, which causes the pressure block 13 to move up and down.
That is, | it can fix different diameters of thin and thick workpieces to process. | A plurality of first threaded holes 27 are opened on one side of the fixed platform 10. | 20 The fixed clamp seat 14 is mounted on the upper surface of the fixed platform 10 by | locking screws and the first threaded holes 27. A plurality of second threaded holes | are opened on the lower bottom surface of the pressure plate 11, and the plurality | of second threaded holes are in one-to-one correspondence with the plurality of | first threaded holes 27. The pressure block 13 is fixed on the lower bottom surface | 25 of the pressure plate 11 by screws and the second threaded holes. | The fixed clamp seat 14 can be arbitrarily mounted on the surface of the fixed | platform 10 having the first threaded holes 27 through disassembly and assembly : of screws, so that the position and number of the fixed clamp seat 14 can each be | 30 adjusted. | A first gas nozzle 13 is mounted on the slide seat 2.

A plurality of first branch pipes are connected to the first control
| gas pipe 4. A plurality of synchronous gas pipes 26 are embedded in the 99101685 2 pressure platform 17, and the plurality of synchronous gas pipes 26 are in | communication with a plurality of gas holes 9, respectively.
The plurality of first | branch pipes are in communication with the plurality of synchronous gas pipes 26, | 5 respectively. | The first gas nozzle 3 is connected to a gas pressure controller of the machine tool. | When the gas pressure controller changes the gas pressure of the first gas nozzle | 3, the gas pressure in the gas hole 9 increases or decreases, the piston 7 and the | 10 gas rod 8 rise or fall, and the fixed platform 10 rises or falls with the plurality of gas rods 8, so that different heights can be adjusted as needed when the workpiece is processed. | A second gas nozzle 5 is mounted on the slide seat 2.

| rollers 22 at an equal distance therein, and the upper ends of the plurality of rollenay101685 | 22 abut against the lower bottom wall of the slide seat 2.
| The roller 22 rolls in the sliding process of the slide seat 2, which reduces the | 5 friction force between the slide seat 2 and the slide rail 1, and can reduce the load , of the two slide rods 23.
| In the present invention, when in use, the second gas nozzle 5 is controlled to | perform air extraction by the gas pressure controller inherent in the machine tool, | 10 the plurality of fixed pneumatic screwdrivers 18 rotate reversely, the threaded cap | | 16 rotates reversely, and the threaded rod 15 is threadedly rotated out from the | threaded cap 16 to move up.

As the fixed pneumatic screwdriver 18 continues to . rotate forwardly, the threaded cap 16 is locked on the lower bottom surface of the | 20 fixed platform 10. At this time, the pressure block 13 and the fixed clamp seat 14 | firmly clamp the workpiece. Next, the first gas nozzle 3 is controlled to pressurize, | and the piston 7 and the gas rod 8 move upwardly in a high-pressure state, so that | the fixed platform 10 moves up, and stops when moving up to a proper position. | Then, the third gas nozzle 20 is controlled to pressurize, and the cylinder 25 slides . 25 along the two slide rods 23, so that the slide seat 2 slides on the slide rail 1, and the ; slide seat 2 moves to the designated area and then stops for starting processing.
| The above are only the preferred embodiments of the present invention, but the | scope of protection of the present invention is not limited to this. All the equivalent | 30 replacements or changes made by any person skilled in the art within the technical | scope disclosed by the present invention according to the technical solutions of the | present invention and the invention concept thereof should be covered within the | scope of protection of the present invention.
