Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of machine tool processing, in particular to a bed mechanism applied to a PCB gong machine. Background Art
[0002] The bed structure of a PCB router refers to the structural components used to support and move the machine's bed. A PCB router is a device used to separate circuit boards, and the bed structure plays a crucial role in its normal operation. PCB routers are typically located on the second floor or above of a factory. Because they need to be used on upper floors, the weight of the equipment must be reduced. The bed structure is typically made of marble, which features high precision, good stability, and resistance to deformation. However, its disadvantages are its high density, which makes it too heavy. Furthermore, marble is prone to irreparable scratches due to the milling cutter's inaccurate machining depth and the milling cutter's bouncing during cutting.
[0003] The patent document CN215238062U, which has been published, discloses a gong machine with a limiting function, including a gong machine body, a gong plate mechanism on the gong machine body, a gong plate mechanism including a tool handle, a milling cutter fixedly mounted on the tool handle, a limiting mechanism slidably mounted on the milling cutter, the top of the limiting mechanism and the tool handle fixedly connected together, the limiting mechanism including a first annular block and a second annular block, the milling cutter both passing through the first annular block and the second annular block, two connecting rods fixedly mounted on the top of the second annular block, the tops of the two connecting rods both fixedly connected to the tool handle, and two screws slidably mounted on the second annular block. This allows the milling cutter's cutting depth to be precisely controlled, ensuring that the depth of the gong groove on the PCB board made by the milling cutter is always maintained at a specified depth without damaging the PCB board.
[0004] When the above device is in use, when the processing tool is used to process the material, it uses the pressure of the first annular block on the second annular block to limit the processing position of the milling cutter. If the milling cutter processes the edge of the material, at this time, some positions of the first annular block are not in contact with the material, and a small amount of tilting distance is likely to occur between the non-contacted part and the contacted part, which creates tilting resistance to the milling cutter processing. At the same time, it uses the spherical mechanism to facilitate the tool to follow the tool holder to move to a fixed area. During the milling cutter processing stage, due to the small friction between the contact surface of the sphere and the material, the tool processing is likely to shake, and then the tool bounce phenomenon occurs.
[0005] Therefore, the present application proposes a bed mechanism for a PCB gong machine. Summary of the Invention
[0006] The purpose of the present invention is to address the problem in the background technology that a ball mechanism is used to facilitate the tool to follow the tool holder to move to a fixed area.

An auxiliary spring is fixedly connected between the corresponding downward pressure column and the fixed holding block. The bottom of the corresponding downward pressure column is rotatably connected to a double-layer airbag ball. The two sides of the corresponding downward pressure column are fixedly connected to a sliding rail rod. The inside of the sliding rail rod is fixedly connected to a fixed air transmission tube, one side of the fixed air transmission tube is fixedly connected to an external spring airbag, and the bottom of the fixed air transmission tube is fixedly connected to a friction pattern block.
[0012] Optionally, the outer side of the hydraulic transmission rod is rotatably connected to a first helical gear, and both sides of the clamping ring are rotatably connected to two second helical gears, and the two second helical gears are meshed and connected to the outer side of the first helical gear.

[0014] Optionally, the second bevel gear is fixedly connected to a guide fan on one side of the clamping ring through a fixed clamping block, and the number of the guide fans is two, and the two guide fans are arranged at opposite blowing positions on both sides of the first bevel gear.
[0015] Optionally, the machine tool support assembly further includes a processing waste collection box, which is fixedly mounted on the inner wall of the support base.
[0016] Optionally, the processing table assembly includes a processing table, which is slidably connected to a support base, and the internal threads of the processing table are connected to two first threaded transmission rods, and the same number of auxiliary motors are fixedly connected between the two first threaded transmission rods and the support base.
[0017] Optionally, the processing table assembly further includes two bidirectional clamping blocks, which are fixedly mounted on both sides of the processing table, and an auxiliary sliding groove is provided on one side of the bidirectional clamping block located on the support base.
[0018] Optionally, the bottom of the bidirectional clamping block is fixedly connected to a plurality of movable pushing rods through auxiliary sliding grooves, and the two sides of the processing waste collection box are rotatably connected to a plurality of turntables.
[0019] Optionally, the number of the movable pushing rods is the same as that of the turntable, and a spring block is hinged at the bottom of the movable pushing rod, and the side of the spring block away from the movable pushing rod is fixedly mounted on the turntable.
[0020] Optionally, a closing door is fixedly connected to one side of the turntable, a corresponding spring is fixedly connected between the turntable and the processing waste collection box, and the processing waste collection box is provided with a plurality of induction grooves adapted to the closing door. Under normal circumstances, the closing door is flush with the upper surface of the processing waste collection box.
[0021] Compared with the prior art, the present invention has the following beneficial technical effects:
[0022] 1. If the machining tool is processed along the Y-axis, the double-layer airbag ball rolls on the material along the corresponding downward pressure column to a fixed area, which facilitates the movement of the tool to the specified direction. As the machining tool follows the hydraulic transmission rod to move downward to cut the material, the double-layer airbag ball continues to move downward and contacts the material under pressure. The external spring airbag is squeezed under the limit of the surface spring, and the internal airflow is transmitted to the friction pattern block through the fixed air transmission tube. The friction pattern block is expanded by the airflow, and its flat side contacts the material. The friction pattern on its surface increases the resistance of the double-layer airbag ball when it contacts the material. When the machining tool is cutting, the friction pattern block and the double-layer airbag ball provide buffering, thereby reducing the tool shaking, improving the processing accuracy of the PCB board groove, and reducing the wear caused by the collision between the milling cutter and the material when it shakes;
[0023] 2. As the machining tool moves downward to process the material, the double-layer airbag ball is pressurized and drives the corresponding downward pressure column to slide upward along the inner cavity of the fixed clamping block under the limit of the auxiliary spring, positioning the machining area, limiting the downward movement distance between the hydraulic transmission rod and the machining tool, and at the same time providing good support for the tool during cutting, reducing the shaking of the tool, so that the depth of the milling cutter's groove on the PCB board can always be maintained at the specified position without causing damage to the PCB board;
[0024] 3. The second bevel gear drives the first bevel gear to rotate along the hydraulic transmission rod by meshing with the first bevel gear. The hydraulic transmission rod meshes with the other second bevel gear, causing the two second bevel gears to rotate in opposite directions. The corresponding induced air fans then blow air in opposite directions, blowing away the waste materials around their respective positions to prevent the waste materials from affecting the cutting of the machining tool.
[0025] 4. As the bidirectional clamping block slides, the long push block fits against the upper surface of the waste collection box, and the long push block pushes the waste accumulated between the long push block and the closed door into the waste collection box. Since the processing table drives the PCB board to move back and forth along the X axis for processing, the waste will not accumulate, making it easier to collect the waste, avoiding the accumulation of waste causing obstruction of the processing table sliding along the X axis.

DETAILED DESCRIPTION
[0039] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.
[0040] Example 1
[0041] like Figure 1 - Figure 7As shown, the bed mechanism of the PCB gong machine proposed in the present invention includes a machine tool support assembly 1, a processing table assembly 2 installed on the machine tool support assembly 1, and a processing transmission assembly 3 installed on the machine tool support assembly 1. An anti-collision knife assembly 4 is installed on the outer side of the processing transmission assembly 3, and limited clamping assemblies 5 are installed on both sides of the anti-collision knife assembly 4;
[0042] The machine tool support assembly 1 includes a support base 101, and two bidirectional clamping blocks 103 are fixedly installed on both sides of the support base 101;
[0043] The processing transmission assembly 3 includes two transverse positioning frames 304, and the two transverse positioning frames 304 are fixedly installed between the two bidirectional holding blocks 103. The outer side of the transverse positioning frame 304 is fixedly connected with a tilting link 305, and the tilting link 305 is rotatably connected with a second threaded transmission rod 303. The outer side of the second threaded transmission rod 303 is threadedly connected with a bidirectional clamping frame 302, and the top of the bidirectional clamping frame 302 is fixedly connected with a hydraulic telescopic assembly 301. The two second threaded transmission rods 303 are driven by a forward and reverse motor connected to the second threaded transmission rod 303 to rotate along the inner cavity of the bidirectional clamping frame 302, so that the bidirectional clamping frame 302 drives the anti-collision knife assembly 4 below to slide along the Y axis for processing;
[0044] The anti-collision knife assembly 4 includes a hydraulic transmission rod 402, which is fixedly mounted on the output shaft of the hydraulic telescopic assembly 301. The outside of the hydraulic transmission rod 402 is fixedly connected to a fitting groove 306, and the outer wall of the fitting groove 306 is rotatably connected to a gear clamping ring 405. The bottom end of the gear clamping ring 405 is fixedly connected to a clamping ring 403. The hydraulic transmission rod 402 is located in the center of the clamping ring 403. Two fixed clamping blocks 410 are fixedly connected on both sides of the clamping ring 403. The bottom of the hydraulic transmission rod 402 is fixedly connected to a processing tool 404. The hydraulic transmission rod 402 is telescopically moved by the hydraulic telescopic assembly 301, so that the hydraulic transmission rod 402 drives the rotating processing tool 404 below to process the material, thereby completing the processing in the Z-axis direction.
[0045] The limit clamping assembly 5 includes a corresponding downward pressure column 501, which is slidably connected to the inside of the fixed holding block 410. An auxiliary spring 502 is fixedly connected between the corresponding downward pressure column 501 and the fixed holding block 410. The bottom of the corresponding downward pressure column 501 is rotatably connected to a double-layer airbag ball 504. The two sides of the corresponding downward pressure column 501 are fixedly connected to a slide rail rod 505. The interior of the slide rail rod 505 is fixedly connected to a fixed air transmission tube 506. One side of the fixed air transmission tube 506 is fixedly connected to an external spring airbag 503. The bottom of the fixed air transmission tube 506 is fixedly connected to a friction pattern block 507. When the hydraulic transmission rod 402 moves downward, the gear locking ring 405 drives the clamping ring 403 to move downward synchronously. As the double-layer airbag ball 504 moves downward, if the machining tool 404 is processed along the Y axis, the double-layer airbag ball 504 will not excessively contact the material. At this time, the double-layer airbag ball 504 moves along the corresponding The inner part of the down-pressure column 501 rolls on the material to a fixed area, which facilitates the movement of the tool to the specified direction. As the processing tool 404 follows the hydraulic transmission rod 402 to move downward to cut the material, the double-layer airbag ball 504 continues to move downward and contacts the material under pressure. The double-layer airbag ball 504 is deformed under pressure and expands outward. The expanded position of the double-layer airbag ball 504 squeezes the external spring airbag 503. The external spring airbag 503 is squeezed under the limit of the surface spring, and the internal airflow is transmitted to the friction block 507 through the fixed air transmission tube 506. The friction block 507 is expanded by the airflow, and its flat side contacts the material. The friction pattern on its surface increases the resistance of the double-layer airbag ball 504 when it contacts the material. When the processing tool 404 is cutting, the friction pattern block 507 and the double-layer airbag ball 504 provide buffering, thereby reducing the tool shaking, improving the processing accuracy of the PCB board groove, and reducing the wear caused by collision with the material when the milling cutter shakes.
[0046] Example 2
[0047] like Figure 1 - Figure 6 As shown, based on Example 1, the outer side of the hydraulic transmission rod 402 is rotatably connected to the first bevel gear 401, and the two sides of the clamping ring 403 are rotatably connected to two second bevel gears 409, and the two second bevel gears 409 are meshed and connected to the outer side of the first bevel gear 401.
[0048] In this embodiment, the outer side of the gear locking ring 405 is fixedly connected to the first gear 406, the outer side of the first gear 406 is meshed with the second gear 407, the top of the second gear 407 is fixedly connected to the motor 408, the motor 408 is fixedly connected to the outer side of the hydraulic transmission rod 402, and a pressure sensor is provided on the outer wall of the double-layer airbag ball 504. Before the processing tool 404 processes the material, the motor 408 drives the second gear 407 to rotate, and the second gear 407 drives the first gear 406 to rotate by meshing with the first gear 406, and the first gear 406 drives the clamping ring 403 to rotate along the fitting groove 306. In the prior art, the processing tool 404 can be rotated when loaded in the equipment, and when the clamping ring 403 rotates along the outer side of the processing tool 404, the meshing between the two second bevel gears 409 and the first bevel gear 401 Under the support of the two limit clamping assemblies 5, as the processing tool 404 moves downward to process the material, the double-layer air bag ball 504 is pressurized and drives the corresponding downward pressure column 501 to slide upward along the inner cavity of the fixed clamping block 410 under the limit of the auxiliary spring 502 to position the processing area, so that the hydraulic transmission rod 402 and the processing tool 404 move downward by a limited distance, and at the same time play a better supporting role when the tool is cutting, reducing the shaking of the tool, so that the depth of the milling cutter groove on the PCB board can always be kept at the specified position, and will not cause damage to the PCB board;
[0049] The second bevel gear 409 passes through the fixed clamping block 410 and is fixedly connected to one side of the clamping ring 403 with an air guide fan 411. There are two air guide fans 411, and the two air guide fans 411 are set at opposite blowing positions on both sides of the first bevel gear 401. As the motor 408 stops driving the first gear 406 to rotate, that is, after the processing position of the processing tool 404 is positioned, as the processing tool 404 rotates along the inside of the hydraulic transmission rod 402, one of the second bevel gears 409 is connected to a corresponding motor, and the corresponding motor drives the second bevel gear 409 to rotate, and the second bevel gear 409 drives the first bevel gear 401 to rotate along the hydraulic transmission rod 402 by meshing with the first bevel gear 401. The hydraulic transmission rod 402 meshes with the other second bevel gear 409, causing the two second bevel gears 409 to rotate in opposite directions. The blowing directions of the corresponding air guide fans 411 are opposite, blowing away the waste around their respective positions to prevent the waste from affecting the cutting of the processing tool 404.
[0050] Example 3
[0051] like Figure 4 - Figure 8 As shown, based on the above-mentioned embodiment 1 or 2, the machine tool support assembly 1 further includes a processing waste collection box 102, which is fixedly mounted on the inner wall of the support base 101, and the processing waste collection box 102 is used to store waste generated by processing. The processing table assembly 2 includes a processing table 201, and the processing table 201 is slidably connected to the support base 101. The internal thread of the processing table 201 is connected to two first threaded transmission rods 203, and the same number of auxiliary motors are fixedly connected between the two first threaded transmission rods 203 and the support base 101. When the auxiliary motor drives the first threaded transmission rods 203 to rotate, the processing table 201 slides along the top of the processing waste collection box 102 to cooperate with the processing transmission assembly 3 to complete the processing of the workpiece in the X-axis direction;
[0052] When the waste is scattered into the gap between the support base 101 and the side of the processing waste collection box 102 by the blowing of the guide fan 411, or the staff uses an air gun to clean the surface of the PCB board by air impact, and the coolant sprayed to protect the processing tool 404, the auxiliary motor drives the two first threaded transmission rods 203 to rotate through the output shaft, and the processing table 201 is transmitted along the thread of the first threaded transmission rod 203, resulting in a gap between the processing table 201 and the processing waste collection box 102, causing the waste accumulated on the processing table 201 in the sliding position to fall from the gap into the processing waste collection box 102.
[0053] Example 4
[0054] like Figure 4 - Figure 10 As shown, based on the above-mentioned embodiment 1 or 3, the processing table assembly 2 also includes two bidirectional clamping blocks 202, and the two bidirectional clamping blocks 202 are fixedly installed on both sides of the processing table 201. The bidirectional clamping block 202 is located on one side of the support base 101 and is provided with an auxiliary slide groove. The bottom of the bidirectional clamping block 202 is fixedly connected with a plurality of movable pushing rods 204 through the auxiliary slide groove. The two sides of the processing waste collection box 102 are rotatably connected with a plurality of turntables 206. The number of movable pushing rods 204 is the same as that of the turntables 206. The bottom of the movable pushing rod 204 is hinged with a spring block 205, and the spring block 205 is fixedly installed on the turntable 206 away from the side of the movable pushing rod 204.
[0055] In this embodiment, a closing door 207 is fixedly connected to one side of the turntable 206, and a corresponding spring is fixedly connected between the turntable 206 and the processing waste collection box 102. The processing waste collection box 102 is provided with a plurality of induction grooves adapted to the closing door 207. The closing door 207 is flush with the upper surface of the processing waste collection box 102 under normal conditions. A plurality of pushing long blocks 208 are fixedly connected to the bottom of the two-way clamping block 202. Each pushing long block 208 is located between every two closing doors 207. As the processing table 201 moves along the processing waste collection box 102 in a direction away from the first threaded transmission rod 203, the two-way clamping block 202 assists the movable pushing rod 204 in the slide groove to move synchronously. The movable pushing rod 204 pushes the spring block 205. The spring block 205 is deflected by the thrust of the movable pushing rod 204 and the limit of the turntable 206, and the spring block 205 pushes the turntable 206 to rotate clockwise, and the turntable 206 drives the closing door 207 to rotate synchronously, and the gap between the induction groove and the closing door 207 gradually becomes larger. As the two-way clamping block 202 slides, the pushing long block 208 is attached to the upper surface of the processing waste collection box 102, and the pushing long block 208 pushes the waste accumulated between the pushing long block 208 and the closing door 207 into the processing waste collection box 102. Since the processing table 201 drives the PCB board to move back and forth along the X axis for processing, the waste will not accumulate, thereby making it easier to collect the waste, and avoiding the accumulation of waste causing the processing table 201 to be blocked from sliding along the X axis;
[0056] Here, if Figure 11 - Figure 12 The processing table 201 in the present invention is assembled by a splicing scheme. A relatively thin panel is used on the top to connect with other workpieces that need to be installed on the top. The bottom is connected to the upper panel by a splicing pillar. The joints are bonded with special adhesives, and bolts are used for secondary reinforcement at the positions where bonding is required, so that it can achieve the same firmness as a whole, reducing the weight of the overall structure. At the same time, due to the splicing structural characteristics of the processing table 201, the middle area of its lower part is hollow, which makes its weight reduced by about one third compared with the overall structure. In addition, the raw materials required for splicing are less than those for overall processing, and the cost of raw materials is reduced.
[0057] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
