DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be appreciated that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some but not all structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present application.

[0034] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] The present invention specifically provides a plate fixing platform for a multi-axis drilling machine, such as Figure 1-Figure 13 As shown, it includes: a mounting table 11 for holding the plate 500 during processing, the plate 500 to be drilled is placed on the mounting table 11, and is fixed on the mounting table 11 before processing, referring to Figure 3 As shown, the mounting platform 11 is symmetrically cross-spaced with movable grooves 12, and a longitudinal screw rod 13 and a transverse screw rod 131 are rotatably installed in the cross-spaced movable grooves 12. Clamping blocks 14 are connected to both sides of the transverse screw rod 131 and the longitudinal screw rod 13. The longitudinal screw rod 13 and the transverse screw rod 131 are bidirectional screw rods. As the longitudinal screw rod 13 and the transverse screw rod 131 rotate, the clamping blocks 14 can move closer to or farther away from each other. Therefore, after the plate 500 is placed on the mounting platform 11, the clamping blocks 14 in four directions move closer to each other, so that the plate 500 can be pushed toward the middle of the mounting platform 11, and finally the plate 500 is moved to the middle of the mounting platform 11. The clamping block 14 is clamped on the mounting table 11; wherein, the drilling equipment will have multiple drill bits, and thus multiple mounting tables 11 will be matched and arranged on the equipment. The multiple mounting tables 11 need to be horizontally connected through a connecting frame 16, and the horizontal screw rods 131 on the multiple mounting tables 11 are connected end to end with each other. At this time, only one external motor is needed to drive all the horizontal screw rods 131 to rotate, so as to realize the synchronous rotation of the horizontal screw rods 131. A synchronous drive device 15 is fixedly installed on the side edge of the mounting table 11, and the synchronous drive device 15 is connected to the multiple longitudinal screw rods 13 for synchronous drive.

[0036] When in use, it is only necessary to place the plate 500 to be punched on the mounting table 11, and the synchronous drive device 15 simultaneously drives multiple longitudinal screws 13 to rotate, and the transverse screw 131 is also driven to rotate, so that the clamping blocks 14 on each mounting table 11 are close to each other, so as to clamp the plates 500 on each mounting table 11 at the same time.

[0037] The present invention cooperates with each other through the cross-arranged longitudinal screw rods 13 and transverse screw rods 131 to drive the clamping blocks 14 to approach each other toward the central area, and the plate 500 placed on the mounting table 11 will be pushed to the middle position and clamped and fixed, so that the plate 500 can be automatically clamped in the middle position of the mounting table 11; after multiple transverse screw rods 131 are connected end to end, the longitudinal screw rods 13 are driven to rotate together by the synchronous drive device 15, so that multiple mounting tables 11 can achieve synchronous clamping and fixation of the plate 500.

[0038] Reference Figure 4 As shown, the clamp block 14 also includes a downwardly inclined stepped tooth 141 protruding from the top edge. When the clamp block 14 is clamping the plate 500, the stepped tooth 141 at the top of the clamp block 14 will be inverted on the top edge of the plate 500 and exert downward pressure, thereby maintaining the stability of the plate 500 when clamped.

[0039] Reference Figure 3 and Figure 7 As shown, it also includes: mounting holes 21 are opened on the side walls on both sides of the edge of the mounting platform 11, a driving motor 22 is installed in the mounting hole 21, an external hexagonal shaft 23 is fixedly installed on the output shaft of the driving motor 22, a guide slide frame 24 is provided in front of the driving motor 22, a material rack 25 is pluggably arranged on the guide slide frame 24, isolation belts 26 are symmetrically arranged on both sides of the material rack 25, a reduction device 261 is arranged on the side edge of the material rack 25, and is connected to the isolation belt 26 through a transmission shaft 262, the reduction device 261 is a reduction structure composed of a plurality of gear combinations, a hexagonal connecting hole 263 is provided at the lower part of the reduction device 261, and the surface of the isolation belt 26 is protrudingly provided with separation holes The separating teeth 27 are used to insert the plate 500 into the gap of the separating teeth 27, so that the plate 500 is lifted up and mounted on the material rack 25 through the separating teeth 27. When in use, the material rack 25 is placed on the guide sliding rack 24, and then the material rack 25 is pushed to slide close to the driving motor 22. The inner hexagonal connecting hole 263 of the reduction device 261 is connected to the outer hexagonal shaft 23. As the driving motor 22 is driven, the isolation belt 26 can rotate. Through the rotation of the isolation belt 26, the upper plate 500 can be moved downward, and an ejection mechanism 28 is installed on the guiding sliding rack 24. The ejection mechanism 28 can push the plate 500 that falls from the material rack 25 onto the mounting table 11.

[0040] Specifically, when in use, the plate 500 that needs to be punched can be pre-stored on the rack 25, and then the rack 25 is pushed so that the reduction device 261 on the rack 25 is connected to the drive motor 22. When the punching of the plate 500 on the mounting table 11 is completed, the plate 500 is taken away, and then the drive motor 22 drives the isolation belt 26 to rotate, so that the plate 500 descends, and finally the bottom plate 500 is pushed onto the mounting table 11 by the ejection mechanism 28, and then the plate 500 is clamped by the clamping block 14 to complete the loading.

[0041] Reference Figure 3 , Figure 5 and Figure 6 As shown, the clamping block 14 on the side close to the driving motor 22 is a fixed block 31, and the fixed block 31 is connected to the longitudinal screw rod 13. The movable block 32 is slidably arranged on the fixed block 31 through the guide rails 35 arranged on both sides of the fixed block 31. The top of the movable block 32 is provided with downwardly inclined stepped teeth 141, and the side walls on both sides of the movable block 32 are provided with protrusions 33. The two ends of the first spring 34 are respectively connected to the fixed block 31 and the movable block 32, and are used to pull the two closer to each other. Through the pulling of the first spring 34, the movable block 32 will be hidden in the movable groove 12 under normal conditions. An oblique groove 36 is obliquely opened on the inner side wall of the movable groove 12, and the oblique groove 36 extends to the table top of the mounting table 11, and the protrusion 33 is placed in the oblique groove 36. The protrusion 33 moves along the oblique groove 36 to make the movable block 32 move upward.

[0042] In order to prevent the clamping block 14 from blocking the sheet 500 from being pushed from the material rack 25 to the mounting table 11, the protrusion 33 on the movable block 32 slides down along the inclined groove 36 to be hidden in the movable groove 12. At this time, the pushed-out sheet 500 will not be blocked and can be smoothly pushed onto the mounting table 11. When it is necessary to clamp the sheet 500, the longitudinal screw 13 will rotate, the fixed block 31 and the clamping block 14 on the other side will approach each other, and the movable block 32 will move along the inclined groove 36 and then start to move upward, and finally the movable block 32 will completely rise to the table surface of the mounting table 11, so as to cooperate with other clamping blocks 14 to complete the clamping of the sheet 500.

[0043] Reference Figure 7 and Figure 8 As shown, the guide sliding frame 24 includes: a base 241 arranged in front of the driving motor 22, a guide bar 242 installed in the base 241, a slide plate 243 slidably arranged on the guide bar 242, pin holes 244 are evenly spaced on the slide plate 243, and a latch 2441 is arranged at the bottom of the material rack 25, and the position of the latch 2441 matches the position of the pin hole 244.

[0044] When in use, the pin 2441 at the bottom of the material rack 25 is inserted into the pin hole 244 for fixing, and then the material rack 25 can be pushed to slide in the base 241, so that the inner hexagonal connection hole 263 of the reduction device 261 can be connected to the outer hexagonal shaft 23 of the drive motor 22. A locking mechanism is provided at the inner hexagonal connection hole 263 of the reduction device 261, and the locking mechanism locks the rotation of the inner hexagonal connection hole 263 by pressing and pushing, so as to prevent the isolation belt 26 from rotating spontaneously and causing the plate 500 placed on the isolation belt 26 to fall off.

[0045] Reference Figure 8 As shown, it also includes: a positioning pin 245 movably inserted on the slide plate 243, and holes matching the positioning pin 245 are provided on the guide bar 242 at intervals. In order to prevent the outer hexagonal shaft 23 of the driving motor 22 from being disengaged after being inserted into the inner hexagonal connecting hole 263, after the connection is completed, the positioning pin 245 is inserted into the hole on the guide bar 242, so that the slide plate 243 cannot slide, so as to prevent the outer hexagonal shaft 23 of the driving motor 22 from being disengaged after being inserted into the inner hexagonal connecting hole 263.

[0046] Reference Fig.11 As shown, the ejection mechanism 28 includes: a fixed frame 281, both sides of the fixed frame 281 are connected to the base 241, a transmission screw 282 is rotatably arranged on the fixed frame 281, a moving platform 283 is connected to the transmission screw 282, a telescopic push block 284 is installed on the moving platform 283, and a power output device 285 is installed on the fixed frame 281 to drive the transmission screw 282 to rotate. Specifically, when in use, the power output device 285 drives the transmission screw 282 to rotate, so that the moving platform 283 moves, and the telescopic push block 284 will push the plate 500 against the edge of the plate 500 to push the plate 500 onto the mounting platform 11, and as the telescopic push block 284 is extended, the plate 500 can be pushed into the middle of the mounting platform 11.

[0047] Reference Fig.11 As shown, it also includes: a support platform 286 disposed on both sides of the fixing frame 281. When the plate 500 falls from the material rack 25, in order to prevent the falling height from being lower than the table height of the mounting table 11, the plate 500 at the bottom layer is supported by the support platform 286 so that the plate 500 at the bottom layer will not be lower than the table height of the mounting table 11.

[0048] Reference Fig.12 and Fig.13As shown, the locking mechanism includes: a driving gear 41 arranged inside the reduction device 261 is rotated by a fixed rod 42, and the driving gear 41 can rotate and slide on the fixed rod 42, and an inner hexagonal groove 411 that fits with the outer hexagonal shaft 23 is provided on the driving gear 41. When in use, the outer hexagonal shaft 23 is inserted into the inner hexagonal groove 411, and the driving gear 41 can be driven to rotate as the driving motor 22 rotates. The second spring 43 is sleeved on the fixed rod 42 to resist the driving gear 41. Therefore, after the outer hexagonal shaft 23 is inserted into the inner hexagonal groove 411, continuing to push will push the driving gear 41 to move. The second spring 43 is compressed, and a fixed gear 44 is fixedly installed above the driving gear 41. The fixed gear 44 and the driving gear 41 can mesh, but after the driving gear 41 is pushed to move, the driving gear 41 will be disengaged from the fixed gear 44, that is, when the outer hexagonal shaft 23 is not inserted into the driving gear 41, the second spring 43 pushes the driving gear 41 and the fixed gear 44 to mesh. After the two gears are meshed, the driving gear 41 cannot rotate. After the driving gear 41 is inserted, the material rack 25 is continuously pushed to disengage the driving gear 41 from the fixed gear 44.

[0049] A driven gear 45 is coaxially connected to the fixed gear 44, and the driven gear 45 can rotate on the shaft. The bevel gear set 46 is coaxially connected to the driven gear 45 and rotates with the driven gear 45. After power is transmitted through the shaft, the transmission shaft 262 is driven to rotate. The external hexagonal shaft 23 is inserted into the driving gear 41 to squeeze the second spring 43 so that the driving gear 41 slides out of the fixed gear 44, but still keeps meshing with the driven gear 45, so that the driving gear 41 can rotate and drive the driven gear 45 to rotate.

[0050] When the reduction device 261 has not yet been connected to the external hexagonal shaft 23, the locking mechanism is in a locked state, so the isolation belt 26 cannot rotate. When the external hexagonal shaft 23 is inserted into the driving gear 41, it continues to push so that the driving gear 41 is disengaged from the fixed gear 44. At this time, the driving gear 41 can rotate and can be driven by the drive motor 22.

[0051] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
