Description

Technical Field

[0001] The present invention belongs to the technical field of automotive parts production, and specifically relates to a CNC numerical control machining device for automotive parts production. Background Art

[0002] CNC machining generally refers to computerized numerical control precision machining. The main task is to compile machining programs, that is, to convert the original manual work into computer programming. The feed machining route of a CNC lathe refers to the path that the turning tool travels from the tool setting point (or the fixed origin of the machine tool) until it returns to this point and ends the machining program.

[0003] Automotive precision parts refer to the general term for various accessories of farm machinery, electrical appliances, and electronic production equipment and household appliances produced using machinery, electrical appliances, and electronic equipment. Generally, it includes mechanical equipment, electrical equipment, transportation tools, electronic products, electrical products, instruments and meters, metal products, etc. and their parts and components. During the production and assembly of automotive precision parts, it is sometimes necessary to drill holes in different parts so that the parts can be spliced with screws.

[0004] When a CNC numerical control machining equipment drills holes in automotive parts, it needs to be fixed by a fixing mechanism on the equipment first. However, the existing placement methods of automotive parts include manual placement and automatic placement. Manual placement is cumbersome and has low efficiency. Automatic placement generally uses driving parts such as electric cylinders or motors to drive the clamping mechanism to automatically load and unload automotive parts, which requires additional electrical equipment to be installed on the equipment, resulting in higher costs. At the same time, there are more wires, which are prone to scattering and affecting machining.

[0005] Therefore, we propose a CNC numerical control machining device for automotive parts production to solve the problems encountered above. Summary of the Invention

Detailed implementation manners

[0035] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0036] Embodiment: Please refer to Figure 1 - Figure 11 As shown, a CNC numerical control machining device for automobile parts production includes a CNC machine tool 1. In the middle of the inner bottom of the CNC machine tool 1, a bottom plate 4 is provided. On the upper surface of the bottom plate 4, a pushing mechanism 5 and a lifting and rotating mechanism 6 are provided. Inside the CNC machine tool 1, a conveying mechanism 2 is provided. The conveying mechanism 2 includes a servo motor 201. The servo motor 201 is arranged on the right outer wall of the CNC machine tool 1 through a motor base. The power output end of the servo motor 201 is connected to a transmission roller 202 through a coupling. On the surface of the transmission roller 202, a conveyor belt 203 is provided. And two groups of conveyor belts 203 are symmetrically arranged on the left and right. The setting of the two groups of conveyor belts 203 makes the middle space free, avoiding the conveyor belt 203 from affecting the operation of the lifting and rotating mechanism 6. On the surfaces of the two groups of conveyor belts 203, guide strips 204 are fixedly installed by screws. The two groups of guide strips 204 are respectively arranged on the left and right sides of the middle part placement groove 22. On the surfaces of the two groups of conveyor belts 203, a number of limit screw holes 205 are provided.

[0037] It should be noted that the design of the two groups of guide strips 204 can limit and guide the automobile parts on the conveyor belt 203, avoiding the deviation of the automobile parts and affecting the automatic feeding work. The setting of multiple groups of limit screw holes 205 can adjust the position of the guide strips 204, so that the guide strips 204 can guide the automobile parts with different widths, increasing the applicable range of the device.

[0038] The pushing mechanism 5 includes a rotating motor 501, and the rotating motor 501 is arranged on the upper surface of the bottom plate 4. The power output end of the rotating motor 501 is connected to a rotating shaft 502 through a coupling. The rotating shaft 502 is connected to a first rotating rod 504 through a belt transmission device 503. And both the belt transmission device 503 and the first rotating rod 504 are symmetrically arranged in two groups in the front and back. The upper ends of the two groups of first rotating rods 504 are respectively connected to a gearbox 505. The two groups of gearboxes 505 are respectively arranged on the inner walls on the left and right sides of the CNC machine tool 1. The upper end of the gearbox 505 is connected to a second rotating rod 506. At the upper end of the second rotating rod 506, a rotating plate 507 is provided.

[0039] It should be noted that the two groups of belt transmission devices 503 are not on the same horizontal plane, that is, one is above and the other is below. When the two groups of belt transmission devices 503 rotate, they will not affect each other. And the rotation directions of the two groups of gearboxes 505 are opposite. For example, when the left gearbox 505 drives the left second rotating rod 506 to rotate counterclockwise, the right gearbox 505 will drive the right second rotating rod 506 to rotate clockwise, so that the two rotating plates 507 will simultaneously push the automobile parts located in the middle of the two rotating plates 507 backward.

[0040] Inside the rotating plate 507, a third rotating rod 11 is rotatably installed. On the circumferential surface of the third rotating rod 11, a rotating gear 12 is provided, and the upper end of the rotating gear 12 is meshed and connected to the lower end of the toothed plate 508. At the rear end of the third rotating rod 11, a fixing bolt 13 is screwed, and the rear side of the fixing bolt 13 is screwed inside the rear side of the rotating plate 507. One end of the rotating plate 507 close to the rotating motor 501 is movably connected to a pushing block 509 through the toothed plate 508;

[0041] It should be noted that by unscrewing the fixing bolt 13, the third rotating rod 11 loses its fixing effect. At this time, when the third rotating rod 11 is rotated, the toothed plate 508 can be driven to move into or out of the rotating plate 507 through the rotating gear 12, thereby reducing or increasing the overall length of the rotating plate 507, the toothed plate 508 and the pushing block 509, and it can be adjusted according to the length of the automobile parts actually processed, which is convenient for pushing the automobile parts of different lengths backward.

[0042] Above the lifting and rotating mechanism 6, a turntable 7 is provided. Inside the turntable 7, a clamping and fixing mechanism 8 is provided. The clamping and fixing mechanism 8 includes a pushing plate 801 and clamping plates 802. There are two symmetrically arranged clamping plates 802. The pushing plate 801 and the two clamping plates 802 are both provided with four groups and are circumferentially arranged inside the turntable 7. On both sides of the pushing plate 801 inside the turntable 7, a first pushing block 803 is provided. Inside the first pushing block 803, a second pushing block 804 is provided. The ends of the first pushing block 803 and the second pushing block 804 close to each other are both designed in an arc shape. Due to the arc design, when the first pushing block 803 moves horizontally, the first pushing block 803 can smoothly push the second pushing block 804 to move horizontally. One end of the second pushing block 804 is provided with a hinge rod 805, and the other end of the hinge rod 805 is hinged to the clamping plate 802. Four accessory placement slots 22 are circumferentially arranged inside the turntable 7. The four groups of first pushing blocks 803 and clamping plates 802 are respectively arranged at the four accessory placement slots 22. The accessory placement slots 22 provide a placement space for the automobile parts, enabling the automobile parts to be smoothly placed inside the turntable 7. An activity slot 19 and a limit movement slot 20 are opened inside the turntable 7, and the limit movement slot 20 is communicated with the activity slot 19. The first pushing block 803, the second pushing block 804 and the hinge rod 805 are all arranged inside the activity slot 19. The setting of the activity slot 19 provides an activity space for the first pushing block 803, the second pushing block 804 and the hinge rod 805, enabling the first pushing block 803 to smoothly push the second pushing block 804 to move, and then enabling the second pushing block 804 to push the clamping plate 802 to move through the hinge rod 805. A limit activity block 21 is movably installed inside the limit movement slot 20, and the upper end of the limit activity block 21 is connected to the lower surface of the second pushing block 804. The setting of the limit movement slot 20 provides a limit and activity space for the limit activity block 21, enabling the limit activity block 21 to only move horizontally inside the limit movement slot 20, thereby driving the second pushing block 804 to only move horizontally;

[0043] It should be noted that after the automotive part is moved into the part placement groove 22 at the front end of the turntable 7, the rear side of the automotive part abuts against the surface of the front push plate 801. At this time, the thrust of the automotive part is not sufficient to push the push plate 801 backward. By rotating the two sets of pushing blocks 509, the automotive part can be pushed backward, thereby pushing the push plate 801 backward. Then, the push plate 801 pushes the two push blocks 804 away from the push plate 801 through the push blocks 803 on the left and right sides. Then, the push block 804 pushes the clamping plate 802 outward of the turntable 7 through the hinge rod 805, so that the two clamping plates 802 clamp the left and right sides of the automotive part respectively, thereby clamping and fixing the automotive part inside the turntable 7, facilitating subsequent drilling work.

[0044] The lifting and rotating mechanism 6 includes a reciprocating rotating column 601. The lower end of the reciprocating rotating column 601 is connected to the upper end of the rotating shaft 502. The right side of the upper part of the reciprocating rotating column 601 is movably connected with a lifting block 602 through a slider. The rear side inside the lifting block 602 abuts against an annular lifting plate 603 through a ball. The setting of the ball enables the lifting block 602 to drive the annular lifting plate 603 to move vertically while not affecting the lateral rotation of the annular lifting plate 603. A rotating lifting rod 604 is arranged in the middle of the annular lifting plate 603. The upper end of the rotating lifting rod 604 is fixedly connected to the middle of the turntable 7 through a screw. The setting of the screw facilitates the removal of the turntable 7 from the rotating lifting rod 604, and then facilitates the replacement of different turntables 7, enabling the turntable 7 to match more sizes of automotive parts and improving the applicable range of the device. A spur gear 605 is arranged on the circumferential surface of the rotating lifting rod 604, and the spur gear 605 is arranged below the annular lifting plate 603. A sector gear 606 matching the spur gear 605 is arranged on the circumferential surface of the lower end of the reciprocating rotating column 601, and the sector gear 606 is located above the spur gear 605;

[0045] It should be noted that an annular moving groove with a higher left and lower right is formed on the surface of the reciprocating rotating column 601. When the reciprocating rotating column 601 rotates, the lifting block 602 can move up and down reciprocally on the reciprocating rotating column 601, and then can drive the annular lifting plate 603 to move up and down reciprocally. Among them, when the pushing block 509 pushes the automotive parts into the turntable 7, the lifting block 602 moves upward, and during the pushing process of the pushing block 509, the spur gear 605 moves upward and is not on the same horizontal plane as the sector gear 606. After the annular lifting plate 603 drives the turntable 7 and the automotive parts to move above the guide bar 204, at this time, the spur gear 605 and the sector gear 606 are on the same horizontal plane, and at the same time, the sector gear 606 rotates to mesh with the spur gear 605, so that the sector gear 606 can drive the spur gear 605 to rotate horizontally. Then, the spur gear 605 drives the rotating lifting rod 604 and the turntable 7 to rotate horizontally by ninety degrees. Then, the lifting block 602 drives the rotating lifting rod 604 and the turntable 7 to move vertically downward through the annular lifting plate 603, so that after the turntable 7 rotates ninety degrees, it also moves downward and returns to the initial height.

[0046] A fixing block 14 is arranged on the upper surface of the bottom plate 4, and the fixing block 14 is arranged at the rear side of the rotating motor 501. An ascending and descending groove 15 and a rotating groove 16 are successively formed in the fixing block 14 from bottom to top, and the ascending and descending groove 15 and the rotating groove 16 are communicated with each other. The ascending and descending groove 15 is a cross-shaped groove. An ascending and descending clamping block 17 is arranged on the circumferential surface at the lower end of the rotating lifting rod 604, and the ascending and descending clamping block 17 is a cross-shaped clamping block and is located at the bottom of the ascending and descending groove 15. A fixing plate three 18 is arranged at the front end of the fixing block 14. The upper end of the rotating shaft 502 is rotatably installed inside the fixing plate three 18. A fixing rod 608 is arranged at the rear end of the upper surface of the fixing plate three 18. The front end inside of the lifting block 602 is sleeved on the circumferential surface of the fixing rod 608. The upper end of the fixing rod 608 is provided with a fixing plate one 607. The left and right sides of the fixing plate one 607 are respectively fixedly connected with the inner side walls of the CNC machine tool 1. The upper end of the reciprocating rotating column 601 is rotatably installed inside the lower end of the fixing plate one 607;

[0047] It should be noted that when the lifting block 602 drives the annular lifting plate 603 and the rotating lifting rod 604 to move upward, when the ascending and descending clamping block 17 at the lower end of the rotating lifting rod 604 moves upward into the rotating groove 16, the horizontal rotation effect of the rotating lifting rod 604 is released. After the turntable 7 rotates ninety degrees and moves downward so that the ascending and descending clamping block 17 moves into the ascending and descending groove 15, the rotating lifting rod 604 is limited, preventing the rotating lifting rod 604 and the turntable 7 from rotating horizontally and avoiding unnecessary rotation and deviation of the turntable 7, which affects the working effect.

[0048] The upper surface of the turntable 7 is provided with a limiting mechanism 9, and four groups of the limiting mechanisms 9 are arranged in a circumferential array. The limiting mechanism 9 includes an L-shaped mounting block 901, and the L-shaped mounting block 901 is arranged on the upper surface of the turntable 7. An activity rod 902 is movably installed inside the upper end of the L-shaped mounting block 901. A plugging block 904 is arranged at the lower end of the activity rod 902. The lower end of the plugging block 904 penetrates through the turntable 7 and is plugged inside the limiting moving groove 20. A spring 903 is sleeved on the circumferential surface of the activity rod 902. The upper end of the spring 903 is connected to the upper end of the L-shaped mounting block 901, and the lower end of the spring 903 is connected to the upper surface of the plugging block 904. On the upper surface of the rear end of the CNC machine tool 1, there is a second fixing plate 906. The plugging block 904 is designed in an L shape, and the side of the lower end of the plugging block 904 close to the push plate 801 is designed in an arc shape, and the side far from the push plate 801 is designed in a right angle. A semi-circular convex block 905 is arranged at the left end of the second fixing plate 906. The upper end of the semi-circular convex block 905 abuts against the lower surface of the upper part of the plugging block 904. A slot 10 matching the lower end of the plugging block 904 is opened on the upper surface of the push plate 801;

[0049] It should be noted that due to the arc-shaped design of one side of the plugging block 904, when the push plate 801 moves towards the inside of the turntable 7 under the extrusion of the automotive parts, the push plate 801 can push the plugging block 904 upwards, so that the push plate 801 can move to the lower part of the plugging block 904. Then, when the plugging block 904 is subjected to the reaction force of the spring 903, it moves downwards and is inserted into the slot 10 above the push plate 801. Then, due to the right-angle design of the other side of the plugging block 904, when the plugging block 904 is not affected by external forces, it will not move out of the inside of the push plate 801, realizing the fixing effect on the push plate 801. And through the setting of the semi-circular convex block 905 on the rear side of the upper surface of the turntable 7, when the turntable 7 drives the plugging block 904 to rotate horizontally and contact with the semi-circular convex block 905, the semi-circular convex block 905 will push the plugging block 904 upwards, so that the lower end of the plugging block 904 moves out of the slot 10, making the push plate 801 lose the fixing effect, and then making the clamping plate 802 lose the clamping and fixing effect on the automotive parts. Furthermore, the automotive parts can continue to be conveyed backwards under the drive of the conveyor belt 203, realizing the automatic blanking work of the automotive parts.

[0050] A drilling mechanism 3 is provided on the left side of the CNC machine tool 1. The drilling mechanism 3 includes a mounting base 301, and the mounting base 301 is arranged on the outer wall of the left side of the CNC machine tool 1. A second servo motor 302 is provided at the upper end of the outer wall of the left side of the mounting base 301. The power output end of the second servo motor 302 is connected to a threaded rod 303 through a coupling. A moving block 304 is threadedly connected to the circumferential surface of the threaded rod 303. An electric lifting rod 305 is provided at the lower end of the moving block 304. A drilling device 306 is provided at the lower end of the electric lifting rod 305, and the drilling device 306 is arranged above the left-side accessory placement groove 22, capable of performing drilling operations on the accessories moved below the drilling device 306. The setting of the threaded rod 303 can adjust the left-right horizontal position of the drilling device 306, and then drill holes at different positions of the automotive accessories, improving the practicability of the device.

[0051] When the present invention is in use, first place the automotive accessories to be processed in front of the upper surface of the conveyor belt 203, and then start the first servo motor 201. The first servo motor 201 drives the conveyor roller 202 and the conveyor belt 203 to rotate, causing the automotive accessories to move backward. When the automotive accessories move backward and contact the front-end push plate 801, start the rotary motor 501. The rotary motor 501 drives the rotating shaft 502 to rotate. The rotating shaft 502 drives the first rotating rod 504, the gearbox 505, and the second rotating rod 506 to rotate through the belt transmission device 503, causing the second rotating rod 506 to drive the rotating plate 507, the toothed plate 508, and the pushing block 509 to rotate backward, so that the pushing block 509 pushes the automotive accessories backward;

[0052] The automotive accessories move backward and push the front end 801 of the push plate into the turntable 7 backward, causing the first pushing blocks 803 on both left and right sides of the push plate 801 to move backward and push the two second pushing blocks 804 to both sides, so that the two second pushing blocks 804 push the rear ends of the hinge rods 805 to both sides. Then, the front ends of the hinge rods 805 push the clamping plates 802 to approach the side walls of the automotive accessories, causing the two clamping plates 802 to clamp and fix the automotive accessories inside the turntable 7. After the push plate 801 moves backward, the lower end of the insertion block 904 will be inserted into the slot 10, making the push plate 801 position-limited and fixed, further improving the stability of the clamping plate 802;

[0053] Meanwhile, the rotation of the rotating shaft 502 will synchronously drive the reciprocating rotating column 601 to rotate. When the pushing block 509 pushes the automotive parts into the interior of the part placement groove 22, the lifting block 602 on the reciprocating rotating column 601 will move vertically upward. Since the clamping and fixing speed of the automotive parts is relatively fast, the lifting block 602 will not move up by a large height. After the automotive parts are clamped and fixed, the lifting block 602 continues to drive the annular lifting plate 603, the rotating lifting rod 604 and the turntable 7 to move upward. After the turntable 7 and the bottom of the automotive parts move above the guide strip 204, at this time, the spur gear 605 and the sector gear 606 are on the same horizontal plane, and the sector gear 606 rotates to mesh with the spur gear 605. At this time, while the turntable 7 continues to move upward, the sector gear 606 drives the spur gear 605 to rotate horizontally, so that the spur gear 605 drives the rotating lifting rod 604 and the turntable 7 to rotate horizontally by ninety degrees, moving the automotive parts below the drilling device 306. Then, under the continuous rotation of the reciprocating rotating column 601, the lifting block 602 drives the annular lifting plate 603, the rotating lifting rod 604 and the turntable 7 to move downward to the initial height;

[0054] Then, the electric lifting rod 305 drives the drilling device 306 to move downward, so that the drilling device 306 drills the automotive parts. After the drilling of the automotive parts is completed, the turntable 7 continues to rotate horizontally. When the processed automotive parts rotate to the rear side, at this time, the plugging block 904 contacts the semi-circular convex block 905 and is pushed upward by the semi-circular convex block 905, causing the push plate 801 to lose its fixing effect, and then causing the clamping plate 802 to lose its clamping and fixing effect on the automotive parts. At this time, when the conveyor belt 203 rotates, the driving force generated by it can push the drilled automotive parts out of the interior of the part placement groove 22 and convey them backward.
