Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, specifically to an automatic feeding hydraulic shifting machine tool. Background Technology

[0002] CNC machine tools are automated machine tools equipped with a program control system. They use computer-processed code instructions to precisely control the servo system and spindle movement of each coordinate of the machine tool, enabling high-precision automated processing of metal or non-metal raw materials. They are widely used in automobile manufacturing, aerospace, medical devices, mold processing and other fields, and are the basic equipment for modern industry to achieve automated, flexible and intelligent production.

[0003] After the existing machine tools have finished processing the workpiece, the workers usually need to manually remove the processed workpiece from the chuck and then install the workpiece to be processed on the chuck for processing. This manual repeated clamping operation results in long machine downtime, making it impossible to achieve continuous production, thereby reducing production efficiency and increasing labor costs. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic feeding hydraulic shifting machine tool, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] An automatic feeding hydraulic shifting machine tool includes a base and a machine tool. An electric chuck is mounted on the end of the machine tool spindle. A loading / unloading mechanism is provided on the surface of the base. A feeding mechanism is located on one side of the loading / unloading mechanism in the direction of movement, and a receiving mechanism is located on the other side. The loading / unloading mechanism includes a support frame mounted on the surface of the base. A moving plate is mounted below the support frame via an X-axis moving module. A second electric push rod is mounted at the bottom of the moving plate. A U-shaped plate is mounted at the telescopic end of the second electric push rod. Electric clamps are mounted on both sides of the U-shaped plate via Y-axis moving modules.

[0007] Furthermore, the feeding mechanism includes a pallet and a box body mounted on the base surface, with the box body positioned directly above the pallet, and the distance between the bottom of the box body and the surface of the pallet being greater than the diameter of the workpiece. Multiple sets of guide rollers are mounted along the length of the upper surface of the pallet, and a first electric push rod is mounted on one side of the pallet surface, with the end of the telescopic end of the first electric push rod positioned within the distance between the box body and the pallet.

[0008] Furthermore, a baffle is provided on the other side of the pallet surface, and a rubber pad is provided on the surface of the baffle.

[0009] Furthermore, the receiving mechanism includes a receiving plate mounted on the surface of the base, and a surrounding plate is provided around the surface of the receiving plate.

[0010] Furthermore, the receiving plate has an inclined structure with the side closer to the feeding mechanism being higher and the side farther away from the feeding mechanism being lower.

[0011] Furthermore, gears are provided on the outer surface of the machine tool, and a shift plate is provided on the inner side of the gears. The shift plate is connected to the shift fork of the machine tool. A hydraulic cylinder is mounted on the outer surface of the machine tool, and a rack is mounted on the end of the extension and retraction end of the hydraulic cylinder. The rack is slidably connected to the outer surface of the machine tool, and the rack is meshed with the gear.

[0012] Furthermore, multiple linear bearings are installed on the outer surface of the movable plate, and limit posts are slidably installed inside the linear bearings, with the bottom of the limit posts connected to the surface of the U-shaped plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0014] 1. This utility model, through the setting of the loading and unloading mechanism, can simultaneously drive two electric clamps to perform the operations of taking out the processed workpiece and loading the workpiece to be processed, thereby avoiding the tedious operation of manual loading and unloading, reducing equipment downtime, and improving production efficiency.

[0015] 2. This utility model achieves automatic feeding by placing multiple workpieces to be processed inside a box and pushing them under gravity and the first electric push rod. Workers only need to periodically fill the box with workpieces and collect the processed workpieces on the receiving plate, allowing one worker to operate multiple machines at the same time, reducing the number of workers and thus reducing the company's labor costs.

[0016] 3. This utility model uses a hydraulic cylinder to drive the rack to move, which in turn drives the gear to rotate, thereby achieving the purpose of hydraulic drive gear shifting. Compared with traditional manual gear shifting, it saves manpower and is more convenient to operate. Attached Figure Description

The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0024] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0025] An electric chuck 102 is installed at the end of the spindle of the machine tool 101. A loading / unloading mechanism 4 is provided on the surface of the base 1. A feeding mechanism 2 is provided on one side of the loading / unloading mechanism 4 in the direction of movement, and a receiving mechanism 3 is provided on the other side of the loading / unloading mechanism 4 in the direction of movement. The loading / unloading mechanism 4 includes a support frame 401 installed on the surface of the base 1. A moving plate 403 is installed below the support frame 401 via an X-axis moving module 402. A second electric push rod 404 is installed at the bottom of the moving plate 403. A U-shaped plate 405 is installed at the end of the telescopic end of the second electric push rod 404. Electric clamps 407 are installed on both sides of the surface of the U-shaped plate 405 via a Y-axis moving module 406.

[0026] In use, the X-axis moving module 402 drives the moving plate 403 to move to the side close to the feeding mechanism 2. Then, the second electric push rod 404 drives the U-shaped plate 405 to descend, so that the two sets of electric clamps 407 respectively clamp the workpiece processed on the machine tool 101 and the workpiece to be loaded on the feeding mechanism 2. Then, the electric clamp 407 clamping the processed workpiece is pulled out of the machine tool 101 by the Y-axis moving module 406. Then, the second electric push rod 404 drives the U-shaped plate 405 to rise a suitable distance, and the X-axis... The moving module 402 drives the moving plate 403 to move to one side of the receiving mechanism 3. The second electric push rod 404 drives the U-shaped plate 405 to descend to its original position. At this time, the electric clamp 407 on one side releases and places the processed workpiece on the receiving mechanism 3. The electric clamp 407 on the other side, driven by the Y-axis moving module 406, inserts the workpiece to be processed into the electric chuck 102 and clamps it, thereby achieving the purpose of automatic loading and unloading. Loading and unloading can be carried out simultaneously, reducing equipment downtime and improving production efficiency.

[0027] It is worth noting that the two second electric push rods 404 can achieve synchronous driving under the action of the controller, which is a common existing technology, so it will not be elaborated on here.

[0028] Multiple linear bearings 408 are mounted on the outer surface of the movable plate 403. Limiting posts 409 are slidably mounted inside the linear bearings 408. The bottom of the limiting posts 409 is connected to the surface of the U-shaped plate 405.

[0029] By using the linear bearing 408 and the limiting post 409, the second electric push rod 404 can be limited, preventing it from being subjected to lateral forces, thus avoiding deformation and damage to its telescopic rod structure and improving its service life.

[0030] Please see Figure 2 and Figure 3The feeding mechanism 2 includes a pallet 201 and a box 202 mounted on the surface of the base 1. The box 202 is positioned directly above the pallet 201, and the distance between the bottom of the box 202 and the surface of the pallet 201 is greater than the diameter of the workpiece. Multiple sets of guide rollers 203 are mounted along the length of the upper surface of the pallet 201. A first electric push rod 204 is mounted on one side of the surface of the pallet 201, and the end of the telescopic end of the first electric push rod 204 is positioned within the distance between the box 202 and the pallet 201. Multiple workpieces are placed inside the box 202. The bottom workpiece rests on the guide roller 203 on the surface of the pallet 201. The first electric push rod 204 pushes the bottom workpiece out of the bottom of the box 202, moving it to the clamping position for easy loading by the electric clamp 407. After the telescopic end of the first electric push rod 204 is pulled out from the bottom of the box 202, the upper workpieces continue to fall onto the guide roller 203 on the surface of the pallet 201 under gravity, achieving automatic feeding. A baffle 205 is provided on the other side of the surface of the pallet 201, and a rubber pad is provided on the surface of the baffle 205. The baffle 205 is used to position the movement distance of the workpiece, ensuring that the electric clamp 407 can accurately clamp it, and the rubber pad can also act as a buffer, reducing the impact force on the first electric push rod 204.

[0031] Please see Figure 2 The receiving mechanism 3 includes a receiving plate 301 mounted on the surface of the base 1, with surrounding plates 302 arranged around its surface. The electric clamp 407 removes the machined workpiece from the electric chuck 102, moves it above the receiving plate 301, and releases it, allowing the workpiece to fall onto the receiving plate 301. The surrounding plates 302 prevent the workpiece from rolling to the ground. The receiving plate 301 has an inclined structure, higher on the side closer to the feeding mechanism 2 and lower on the side farther from the feeding mechanism 2. This allows the machined workpiece to automatically roll towards the receiving plate 301, avoiding interference with subsequent feeding.

[0032] Please see Figure 4 The machine tool 101 has a gear 5 on its outer surface, and a shift disc on its inner side, which is connected to the shift fork of the machine tool 101. A hydraulic cylinder 501 is mounted on the outer surface of the machine tool 101, and a rack 502 is mounted on the telescopic end of the hydraulic cylinder 501. The rack 502 is slidably connected to the outer surface of the machine tool 101 and meshes with the gear 5. When the hydraulic cylinder 501 is activated, its telescopic end pushes the rack 502 horizontally. Utilizing the meshing relationship between the rack 502 and the gear 5, the gear 5 is driven to rotate, which in turn drives the shift disc to rotate, thereby manipulating the shift fork within the machine tool 101 to achieve hydraulic shifting.

[0033] The specific workflow and working principle of this device are as follows.

[0034] During loading and unloading, the worker first places multiple workpieces to be processed into the box 202. The bottom workpiece falls on the guide roller 203 on the surface of the pallet 201. The first electric push rod 204 pushes the bottom workpiece out of the bottom of the box 202 and moves it to the clamping position.

[0035] Next, the X-axis moving module 402 drives the moving plate 403 to move closer to the feeding mechanism 2. Then, the second electric push rod 404 drives the U-shaped plate 405 to descend, so that the two sets of electric clamps 407 respectively clamp the workpiece processed on the machine tool 101 and the workpiece to be loaded on the feeding mechanism 2. Then, the electric clamp 407 clamping the processed workpiece is pulled out of the machine tool 101 by the Y-axis moving module 406. Then, the second electric push rod 404 drives the U-shaped plate 405 to rise a suitable distance, so that the workpiece to be processed is taken out from the guide roller 203. Then, the X-axis moving module 402 drives the moving plate 403 to descend. Moved to one side of the receiving mechanism 3, the second electric push rod 404 drives the U-shaped plate 405 to descend to its original position. At this time, one side of the electric clamp 407 releases and places the processed workpiece on the receiving plate 301. The other side of the electric clamp 407, driven by the Y-axis moving module 406, inserts the workpiece to be processed into the electric chuck 102 and clamps it. Finally, the second electric push rod 404 drives the two sets of electric clamps 407 to rise to the required height to avoid interfering with the movement of the cutting tool in subsequent processing, thereby achieving the purpose of automatic loading and unloading. Moreover, loading and unloading can be carried out simultaneously, reducing equipment downtime and improving production efficiency.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
