Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts production, in particular to a CNC numerical control processing device for automobile parts production. Background Art

[0002] CNC machining usually refers to computer digital controlled precision machining. The main work is to compile machining programs, that is, to convert the original manual work into computer programming. The feeding machining route of the CNC lathe refers to the path that the lathe tool takes from the tool setting point (or the fixed origin of the machine tool) until it returns to the point and ends the machining program. Auto precision parts refer to the general term for the parts of various agricultural machinery, electrical equipment, electronic equipment and daily life machinery produced by mechanical, electrical and electronic equipment. Generally, they include mechanical equipment, electrical equipment, transportation vehicles, electronic products, electrical products, instruments and meters, metal products, etc. and their parts and components. In the production and assembly process of auto precision parts, sometimes it is necessary to punch holes in different parts, and the parts can be spliced ​​with screws.

[0003] When CNC machining equipment is drilling holes in auto parts, it is necessary to first fix them through the fixing mechanism on the equipment. However, the existing auto parts placement methods include manual placement and automatic placement. Manual placement is cumbersome and inefficient, while automatic placement generally drives the clamping mechanism by providing a drive member such as an electric cylinder or a motor to automatically load and unload auto parts, which requires additional electrical equipment to be installed on the equipment, resulting in higher costs. At the same time, it also results in more wires, which are easily scattered and affect processing.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example: See Figure 1 - Fig.11As shown, a CNC machining device for automobile parts production includes a CNC machine tool 1, a bottom plate 4 is arranged in the middle of the bottom of the CNC machine tool 1, a push mechanism 5 and a lifting and rotating mechanism 6 are arranged on the upper surface of the bottom plate 4, a conveying mechanism 2 is arranged inside the CNC machine tool 1, and 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 seat, and the power output end of the servo motor 201 is connected to a conveying roller 202 through a coupling transmission, and a conveying belt 203 is arranged on the surface of the conveying roller 202, and two groups of conveying belts 203 are symmetrically arranged on the left and right. The arrangement of the two groups of conveying belts 203 leaves a space in the middle to prevent the conveying belts 203 from affecting the operation of the lifting and rotating mechanism 6, and the surfaces of the two groups of conveying belts 203 are fixed with guide strips 204 by screws, and the two groups of guide strips 204 are respectively arranged on the left and right sides of the middle parts placement slot 22, and the surfaces of the two groups of conveying belts 203 are opened with a plurality of limiting screw holes 205; It should be noted that the design of the two sets of guide strips 204 can limit and guide the auto parts on the conveyor belt 203 to prevent the auto parts from deviating and affecting the automatic loading work. The setting of multiple sets of limiting screw holes 205 can adjust the position of the guide strip 204, so that the guide strip 204 can guide auto parts of different widths, thereby increasing the scope of application of the device.

[0022] 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 the rotating shaft 502 through a coupling, and the rotating shaft 502 is connected to the rotating rod 1 504 through a belt transmission device 503. The belt transmission device 503 and the rotating rod 1 504 are both symmetrically arranged in two groups. The upper ends of the two groups of rotating rods 1 504 are both connected to the gearbox 505. The two groups of gearboxes 505 are respectively arranged on the inner walls of the left and right sides of the CNC machine tool 1. The upper end of the gearbox 505 is connected to the rotating rod 2 506, and the upper end of the rotating rod 2 506 is provided with a rotating plate 507. 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, so that 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 rotating rod 2 506 to rotate counterclockwise, the right gearbox 505 will drive the right rotating rod 2 506 to rotate clockwise, so that the two groups of rotating plates 507 will push the automotive accessories located in the middle of the two groups of rotating plates 507 backwards at the same time.

[0023] A rotating rod 3 11 is rotatably installed inside the rotating plate 507, a rotating gear 12 is provided on the circumferential surface of the rotating rod 3 11, and the upper end of the rotating gear 12 is meshedly connected with the lower end of the toothed plate 508, a fixing bolt 13 is screwed to the rear end of the rotating rod 3 11, and the rear side of the fixing bolt 13 is screwed to the rear side of the rotating plate 507, and the end of the rotating plate 507 close to the rotating motor 501 is movably connected to a push block 509 through the toothed plate 508; It should be noted that by unscrewing the fixing bolt 13, the rotating rod three 11 loses its fixing effect. At this time, by rotating the rotating rod three 11, the rotating gear 12 can drive the tooth plate 508 to move into the rotating plate 507, or move out from the rotating plate 507, thereby reducing or increasing the overall length of the rotating plate 507, the tooth plate 508 and the push block 509. It can be adjusted according to the actual length of the automotive parts being processed, so as to facilitate pushing automotive parts of different lengths backward.

[0024] A turntable 7 is arranged above the lifting and rotating mechanism 6, and a clamping and fixing mechanism 8 is arranged inside the turntable 7. The clamping and fixing mechanism 8 includes a push plate 801 and a clamping plate 802. Two clamping plates 802 are symmetrically arranged. The push plates 801 and the two clamping plates 802 are arranged in four groups and arranged in a circular array inside the turntable 7. Push blocks 803 are arranged on both sides of the push plate 801 located inside the turntable 7. Push blocks 804 are arranged inside the push blocks 803. Push blocks 803 and 804 are arranged on both sides of the push blocks 803. The ends of the push block 803 and the clamping plate 802 are all in an arc shape. The arc shape enables the push block 803 to smoothly push the push block 804 to move horizontally when the push block 803 moves horizontally. One end of the push 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. The inner circumferential array of the turntable 7 is provided with four accessory placement slots 22. The four sets of push blocks 803 and the clamping plate 802 are respectively arranged at the four accessory placement slots 22. The accessory placement slots 22 provide a space for the vehicle to move horizontally. The car accessories are provided with a placement space so that the car accessories can be smoothly placed inside the turntable 7. The turntable 7 is provided with a movable groove 19 and a limit movable groove 20, and the limit movable groove 20 is connected with the movable groove 19. The push block 1 803, the push block 2 804 and the hinge rod 805 are all arranged inside the movable groove 19. The setting of the movable groove 19 provides a movable space for the push block 1 803, the push block 2 804 and the hinge rod 805, so that the push block 1 803 can smoothly push the push block 2 804. The second push block 804 moves, and then the second push block 804 pushes the clamping plate 802 to move through the hinge rod 805. The internal movable limit block 21 is movably installed in the limit moving groove 20. The upper end of the limit moving block 21 is connected to the lower surface of the second push block 804. The setting of the limit moving groove 20 provides the limit moving block 21 with a limit and activity space, so that the limit moving block 21 can only move in the horizontal direction inside the limit moving groove 20, thereby driving the second push block 804 to only move in the horizontal direction. It should be noted that after the automobile accessories are moved to the interior of the accessories placement slot 22 at the front end of the turntable 7, the rear side of the automobile accessories abuts against the surface of the front end push plate 801. At this time, the thrust of the automobile accessories is not enough to push the push plate 801 backward. By rotating the two sets of push blocks 509, the automobile accessories 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 1 803 on the left and right sides. Then the push block 804 pushes the clamping plate 802 toward the outside of the turntable 7 through the hinge rod 805, so that the two clamping plates 802 clamp the left and right sides of the automobile accessories respectively, thereby clamping and fixing the automobile accessories inside the turntable 7, which is convenient for subsequent drilling work.

[0025] 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, and the right side of the upper part of the reciprocating rotating column 601 is movably connected to a lifting block 602 through a slider, and the rear side of the lifting block 602 is abutted against an annular lifting plate 603 through a ball bearing. The setting of the ball bearing enables the lifting block 602 to drive the annular lifting plate 603 to move vertically without 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, and the upper end of the rotating lifting rod 604 is connected to the lifting block 602 through a slider. The screw is fixedly connected to the middle of the turntable 7. 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, so that the turntable 7 can match more sizes of automotive accessories, and improves the application range of the device. The circumferential surface of the rotating lifting rod 604 is provided with a spur gear 605, and the spur gear 605 is arranged below the annular lifting plate 603. The circumferential surface of the lower end of the reciprocating rotating column 601 is provided with a fan gear 606 matching the spur gear 605, and the fan gear 606 is located above the spur gear 605; It should be noted that the surface of the reciprocating rotating column 601 is provided with an annular moving groove which is higher on the left and lower on the right, so that when the reciprocating rotating column 601 rotates, the lifting block 602 can reciprocate up and down on the reciprocating rotating column 601, and then can drive the annular lifting plate 603 to reciprocate up and down, wherein, when the push block 509 pushes the automobile parts to the inside of the turntable 7, the lifting block 602 moves upward, and during the pushing process of the push block 509, the spur gear 605 moves upward and is not on the same horizontal plane with the sector gear 606, and when the annular lifting plate 603 carries the After the rotating turntable 7 and the automobile accessories move to the top of the guide bar 204, the spur gear 605 and the fan gear 606 are on the same horizontal plane, and the fan gear 606 rotates to mesh with the spur gear 605, so that the fan gear 606 can drive the spur gear 605 to rotate horizontally, and then the spur gear 605 drives the rotating lifting rod 604 and the turntable 7 to rotate horizontally by ninety degrees, and 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 moves downward and returns to the initial height.

[0026] A fixed block 14 is provided on the upper surface of the bottom plate 4, and the fixed block 14 is arranged on the rear side of the rotating motor 501. A lifting groove 15 and a rotating groove 16 are sequentially opened inside the fixed block 14 from bottom to top, and the lifting groove 15 and the rotating groove 16 are connected. The lifting groove 15 is a cross groove. A lifting block 17 is provided on the circumferential surface of the lower end of the rotating lifting rod 604, and the lifting block 17 is a cross-shaped block and is located at the bottom of the lifting groove 15. A fixed plate three 18 is provided at the front end of the fixed block 14. The upper end of the rotating shaft 502 is rotatably mounted inside the fixed plate three 18. A fixed rod 608 is provided at the rear end of the upper surface of the fixed plate three 18. The front end of the lifting block 602 is sleeved on the circumferential surface of the fixed rod 608. A fixed plate one 607 is provided on the upper end of the fixed rod 608. The left and right sides of the fixed plate one 607 are respectively fixedly connected to the inner side wall of the CNC machine tool 1. The upper end of the reciprocating rotating column 601 is rotatably mounted inside the lower end of the fixed plate one 607. 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, the lateral rotation effect of the rotating lifting rod 604 is released only after the lifting block 17 at the lower end of the rotating lifting rod 604 moves upward to the inside of the rotating groove 16. After the turntable 7 rotates ninety degrees, it moves downward so that the lifting block 17 moves into the lifting groove 15, and then the rotating lifting rod 604 is limited to prevent the rotating lifting rod 604 and the turntable 7 from rotating horizontally, thereby avoiding unnecessary rotation and deviation of the turntable 7, which affects the working effect.

[0027] The upper surface of the turntable 7 is provided with a limit mechanism 9, and the limit mechanism 9 is provided with four groups in a circumferential array. The limit mechanism 9 includes an L-shaped mounting block 901, and the L-shaped mounting block 901 is provided on the upper surface of the turntable 7. A movable rod 902 is movably installed inside the upper end of the L-shaped mounting block 901, and a plug-in block 904 is provided at the lower end of the movable rod 902. The lower end of the plug-in block 904 passes through the turntable 7 and is plugged into the interior of the limit moving groove 20. The circumferential surface of the movable rod 902 is sleeved with a spring 903, and the upper end of the spring 903 is connected to the upper end of the L-shaped mounting block 901. The lower end of the spring 903 is connected to the upper surface of the plug-in block 904. A second fixing plate 906 is provided on the upper surface of the rear end of the CNC machine tool 1. The plug-in block 904 is L-shaped, and the side of the lower end of the plug-in block 904 close to the push plate 801 is arc-shaped, and the side away from the push plate 801 is right-angled. A semicircular protrusion 905 is provided at the left end of the second fixing plate 906. The upper end of the semicircular protrusion 905 abuts against the lower surface of the upper part of the plug-in block 904. The upper surface of the push plate 801 is provided with a slot 10 matching the lower end of the plug-in block 904. It should be noted that the arc-shaped design on one side of the plug-in block 904 enables the push plate 801 to push the plug-in block 904 upward when the push plate 801 is squeezed by the automobile parts and moves toward the inside of the turntable 7, so that the push plate 801 can move to the bottom of the plug-in block 904. Then, when the plug-in block 904 is subjected to the reaction force of the spring 903, it moves downward and is inserted into the inside of the slot 10 above the push plate 801. Then, due to the right-angle design on the other side of the plug-in block 904, the plug-in block 904 will not move out from the inside of the push plate 801 when it is not affected by external forces. The push plate 801 has a fixing effect, and through the arrangement of the semicircular protrusion 905 on the rear side of the upper surface of the turntable 7, when the turntable 7 drives the plug-in block 904 to rotate horizontally until it contacts the semicircular protrusion 905, the semicircular protrusion 905 will push the plug-in block 904 upward, so that the lower end of the plug-in block 904 moves out of the slot 10, causing the push plate 801 to lose its fixing effect, and then the clamping plate 802 loses its clamping and fixing effect on the auto parts, and then the auto parts can continue to be conveyed backwards driven by the conveyor belt 203, realizing the automatic unloading of auto parts.

[0028] A drilling mechanism 3 is arranged on the left side of the CNC machine tool 1, and the drilling mechanism 3 includes a mounting seat 301, and the mounting seat 301 is arranged on the left outer wall of the CNC machine tool 1, and a servo motor 302 is arranged on the upper end of the left outer wall of the mounting seat 301, and the power output end of the servo motor 302 is connected to a threaded rod 303 through a coupling transmission, and the circumferential surface of the threaded rod 303 is threadedly connected to a moving block 304, and an electric lifting rod 305 is arranged at the lower end of the moving block 304, and a drilling device 306 is arranged at the lower end of the electric lifting rod 305, and the drilling device 306 is arranged above the left accessory placement slot 22, and can perform drilling work on the accessories moved to the bottom of the drilling device 306, and the setting of the threaded rod 303 can adjust the left and right horizontal positions of the drilling device 306, and then drill holes in different positions of the automobile accessories, thereby improving the practicability of the device.

[0029] When the present invention is used, the automobile parts to be processed are first placed in front of the upper surface of the conveyor belt 203, and then the servo motor 201 is started. The servo motor 201 drives the conveyor roller 202 and the conveyor belt 203 to rotate, so that the automobile parts move backward. When the automobile parts move backward to contact with the front push plate 801, the rotating motor 501 is started. The rotating motor 501 drives the rotating shaft 502 to rotate. The rotating shaft 502 drives the rotating rod 1 504, the gearbox 505 and the rotating rod 2 506 to rotate through the belt transmission device 503, so that the rotating rod 2 506 drives the rotating plate 507, the tooth plate 508 and the push block 509 to rotate backward, so that the push block 509 pushes the automobile parts backward. The automobile accessory moves backward and pushes the front end 801 of the push plate to move backward into the turntable 7, so that the push blocks 1 803 on the left and right sides of the push plate 801 move backward and push the two push blocks 2 804 to the sides, so that the two push blocks 2 804 push the rear end of the hinge rod 805 to move to the sides, and then the front end of the hinge rod 805 pushes the clamping plate 802 to approach the side wall of the automobile accessory, so that the two clamping plates 802 clamp the automobile accessory and fix it inside the turntable 7. After the push plate 801 moves backward, the lower end of the plug-in block 904 is inserted into the slot 10, so that the push plate 801 is limited and fixed, and the stability of the clamping plate 802 is further improved. At the same time, the rotation of the rotating shaft 502 will synchronously drive the reciprocating rotating column 601 to rotate. When the push block 509 pushes the automobile accessory into the accessory placement slot 22, the lifting block 602 on the reciprocating rotating column 601 moves vertically upward. Because the clamping and fixing speed of the automobile accessory is fast, the lifting block 602 will not move upward to a large height. After the automobile accessory is 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 automobile accessory move to the top of the guide strip 204, this At this time, the spur gear 605 and the fan gear 606 are on the same horizontal plane, and the fan gear 606 rotates to mesh with the spur gear 605. At this time, while the turntable 7 continues to move upward, the fan 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, and the automobile parts are moved to the bottom of the drilling equipment 306. Then, the reciprocating rotating column 601 continues to rotate, and 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; Then the electric lifting rod 305 drives the drilling device 306 to move downward, so that the drilling device 306 drills holes in the auto parts. After the drilling of the auto parts is completed, the turntable 7 continues to rotate horizontally. When the processed auto parts rotate to the rear side, the plug-in block 904 contacts the semicircular protrusion 905 and is pushed upward by the semicircular protrusion 905, causing the push plate 801 to lose its fixing effect, and then the clamping plate 802 loses its clamping and fixing effect on the auto parts. At this time, when the conveyor belt 203 rotates, the driving force it generates can push the drilled auto parts out of the parts placement slot 22 and transport them backward.
