[0010] Preferably, the guide component further includes: The second spring is installed inside the receiving box. There are two second springs, which are arranged symmetrically. The scraper has two blades, each connected to one of the two second springs. A scraper strip is installed on the top of the scraper for scraping and cleaning the feed chute. The channel is located at the bottom of the receiving box and is connected to the first connecting pipe.

[0011] Preferably, the guide component further includes: A connecting cylinder is installed outside one of the scrapers, and a second inclined plate is installed outside the connecting cylinder to guide the debris and prevent the debris in the middle from directly entering the channel. A telescopic column is installed outside another scraper, with one end of the telescopic column away from the scraper installed inside the connecting cylinder.

[0012] Preferably, the grinding mechanism further includes: A movable frame, which is slidably connected to the outside of a first slide rail; The second slide rail is disposed above the movable frame, and the second indexing table is slidably connected to the outside of the second slide rail.

[0013] This invention provides a multifunctional CNC dual B-axis composite grinding machine. It has the following beneficial effects: 1. This multi-functional CNC dual B-axis compound grinder features a receiving mechanism to collect the chips generated during grinding, reducing chip clogging of the first guide rail and preventing interference with the movement of the moving frame. Depending on the size of the grinding wheel used, the operator can choose to use one or two base boxes, adjusting the distance between the two base boxes to adjust the chip receiving range.

[0014] 2. This multi-functional CNC dual B-axis compound grinder, by setting a first indexing table and a second indexing table, precisely rotates the workpiece and grinding wheel to a specified angular position and locks them, ensuring alignment between the grinding wheel and the workpiece. It can also perform corresponding grinding operations at specified angles on the workpiece, eliminating the need for manual adjustment of the grinding wheel or workpiece angles during the grinding process. Furthermore, the distance between the second and first indexing tables is easily adjustable, facilitating workpiece disassembly.

[0015] 3. This multi-functional CNC dual B-axis compound grinder, through a receiving mechanism, uses suction to draw chips into the receiving box, the first connecting pipe, the second connecting pipe, and the base box. Adjusting the first push rod to a reciprocating motion mode controls the horizontal reciprocating motion of the receiving box and the base box, thereby promoting the horizontal movement of the guide assembly, the first spring, and the fixed balls. The fixed balls on both sides impact the first and second connecting pipes, promoting the falling of chips within them. Furthermore, since the height of the openings of the first and second connecting pipes is lower than the height of the circular groove, chips easily adhere to the second adhesive strip, reducing the amount of chips moving into the circular groove.

[0016] 4. This multi-functional CNC dual B-axis compound grinder, through the setting of a guiding component, during the chip receiving process, the scraper at the top of the scraper scrapes the feed chute, promoting the chips to detach from the feed chute and enter the receiving box through the feed chute or be squeezed out of the feed chute and fall onto the first adhesive strip. The chips falling from the chute are slowly dropped into the channel under the guidance of two second inclined plates, avoiding the chips from rapidly entering the channel and causing blockage inside the channel.

The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] like Figures 1-9 As shown, the present invention provides a technical solution: a multi-functional CNC dual B-axis composite grinding machine, which is described below.

[0021] Including grinding machine 1, it also includes: Base 2, which is installed above grinding machine 1; The first indexing table 3 is configured as a torque turntable and is installed above the base 2. The gripper 4 is located above the first indexing table 3. The gripper 4 is a hydraulic chuck. The angle of the gripper 4 can be adjusted by adjusting the first indexing table 3 to complete the loading and unloading of materials and the material supply. Connecting bracket 5 is installed on the outside of base 2; The first slide rail 7 is located above the grinding machine 1; The receiving mechanism 6 is located outside the connecting frame 5. The receiving mechanism 6 includes a first push rod 602, which is an electric push rod. A receiving box 605 is located outside the first push rod 602, and a guide component 606 is located inside the receiving box 605. The first push rod 602 is used to drive the receiving box 605 to receive waste while controlling the guide component 606 to move in the horizontal direction. The grinding mechanism 8 is located outside the first slide rail 7. The grinding mechanism 8 includes a second indexing table 803, which is a torque turntable. A grinding wheel 804 is provided on the top of the second indexing table 803. Multiple grinding wheels 804 are provided. The grinding wheel 804 used is adjusted by adjusting the second indexing table 803. The first indexing table 3 and the second indexing table 803 are used for dual B-axis grinding of materials.

[0022] Before using the equipment, adjust the first indexing table 3 to adjust the angle of the gripper 4 to complete the material loading. According to the grinding requirements, adjust the second indexing table 803 to select the corresponding grinding wheel 804. Then, adjust the grinding mechanism 8 to adjust the specific position of the grinding wheel 804, and the first and second indexing tables 3 work together to complete the material grinding. During the grinding process, the receiving mechanism 6 remains at the bottom of the grinding wheel 804 and the material to handle falling debris.

[0023] Contracting organization 6 also includes: The slide plate 601 is driven to move within the connecting frame 5 by an electric push rod located within the connecting frame 5. The two slide plates 601 are connected by an adjustment rod that can be manually adjusted in length. The slide plate 601 is slidably connected inside the connecting frame 5. The first push rod 602 is installed on the outside of the slide plate 601. The second push rod 603 is configured as an electric push rod and is connected to the telescopic end of the first push rod 602. The bottom box 604 has a frame-shaped panel detachably installed on its top, and the bottom plate of the bottom box 604 is detachable. The bottom box 604 is connected to the telescopic end of the second push rod 603, and a second adhesive strip is installed inside the bottom box 604. A circular groove 607 is formed on the side of the bottom box 604. A filter screen is installed inside the circular groove 607. The circular groove 607 is used to connect to an external exhaust pipe, which is connected to an external exhaust fan.

[0024] The working process of adjusting position 6 of the receiving mechanism: Before using the equipment, select one or two base boxes 604 based on the size of the grinding wheel 804. Adjust the length of the adjusting rod between the two slide plates 601 according to the number of base boxes 604 to separate or fit the two base boxes 604 together. Then adjust the stroke of the electric push rod in the connecting frame 5 to adjust the positions of the slide plate 601, the first push rod 602, the second push rod 603, the base box 604, and the receiving box 605. Then adjust the stroke of the second push rod 603, which will drive the base box 604 and the receiving box 605 to move upward.

[0025] By setting up a receiving mechanism 6, the chips generated during the grinding process are collected, reducing chip blockage of the first slide rail 7 and avoiding affecting the movement of the moving frame 801. Depending on the size of the grinding wheel 804 used, the worker can choose to use one or two base boxes 604, and adjust the distance between the two base boxes 604 to adjust the range of chip receiving.

[0026] A first arc-shaped cover plate 608 is provided with a first adhesive strip on its top, and the first arc-shaped cover plate 608 is installed on the top of the bottom box 604. The first connecting pipe 611 is installed inside the base box 604, and a receiving box 605 is detachably installed on the top of the first connecting pipe 611. Mounting frame 610 is mounted on top of the first arc-shaped cover plate 608; There are two first inclined plates 612, and the first inclined plates 612 are installed inside the mounting frame 610. The third push rod 613 is an electric push rod. There are two third push rods 613. The third push rod 613 is installed on the outside of the first inclined plate 612. There are two second connecting pipes 614. Two other receiving boxes 605 are detachably installed on the top of the second connecting pipes 614. The second connecting pipes 614 are connected to the telescopic end of the third push rod 613 through an elastic block. The openings of the first connecting pipe 611 and the second connecting pipe 614 are lower than the height of the circular groove 607. The connector 609 is made of rubber. The second connecting pipe 614 is deflected inside the connector 609. The connector 609 seals the junction between the second connecting pipe 614 and the bottom box 604. The connector 609 is installed inside the bottom box 604. The second connecting pipe 614 is connected to the bottom box 604 through the connector 609. The angle of the second connecting pipe 614 inside the bottom box 604 is controlled by the third push rod 613 to adjust the falling direction of the debris inside the second connecting pipe 614. The first spring 615 is installed inside the base box 604; A fixed ball 617 is connected to a first spring 615. The stop lever 616 is installed inside the base box 604 and is located below the first spring 615.

[0027] During the grinding process, the working process of receiving mechanism 6 is as follows: Adjusting the first push rod 602 to reciprocating motion mode causes the second push rod 603, the base box 604, and the receiving box 605 to reciprocate horizontally below the grinding wheel 804 and the material, thereby driving the guide assembly 606 to reciprocate horizontally. Simultaneously with the movement of the base box 604, the first spring 615 and the first fixed ball 617 within the base box 604 begin reciprocating horizontally. The first fixed ball 617 repeatedly impacts the first connecting pipe 611 and the second connecting pipe 614, promoting the falling of debris from the first connecting pipe 611 and the second connecting pipe 614 into the base box 604, further promoting the adhesion of the debris to the second adhesive strip within the base box 604.

[0028] As the bottom box 604 moves, some debris falls onto the first arc-shaped cover plate 608 and adheres to the first adhesive strip on the first arc-shaped cover plate 608.

[0029] The process of using the receiving mechanism 6 to ventilate the material box 605: When the external exhaust fan is turned on to exhaust mode, the gas is drawn into the first connecting pipe 611 or the second connecting pipe 614 through the receiving box 605, and then enters the bottom box 604 through the first connecting pipe 611 or the second connecting pipe 614.

[0030] By setting up a receiving mechanism 6, debris is drawn into the receiving box 605, the first connecting pipe 611, the second connecting pipe 614, and the base box 604 through a suction method. Adjusting the first push rod 602 to a reciprocating motion mode controls the reciprocating motion of the receiving box 605 and the base box 604 in the horizontal direction, thereby promoting the horizontal movement of the guide assembly 606, the first spring 615, and the fixing ball 617. The fixing balls 617 on both sides impact the first connecting pipe 611 and the second connecting pipe 614, promoting the debris to fall out of the first connecting pipe 611 and the second connecting pipe 614. Furthermore, since the height of the openings of the first connecting pipe 611 and the second connecting pipe is lower than the height of the circular groove 607, it is easier for the debris to adhere to the second adhesive strip, reducing the amount of debris moving into the circular groove 607.

[0031] Guide component 606 includes: The second arc-shaped cover plate 6061 is detachably installed on the top of the receiving box 605; Feed chute 6062 is provided inside the second arc-shaped cover plate 6061, and several feed chute 6062 are provided; The second spring 6063 is installed inside the receiving box 605. There are two second springs 6063, which are arranged symmetrically. Scraper 6064, two scrapers 6064 are provided, and the two scrapers 6064 are respectively connected to two second springs 6063. A scraper strip is installed on the top of the scraper 6064, and the scraper strip is made of elastic material. Channel 6068 is located at the bottom of receiving box 605 and is connected to the first connecting pipe 611. A connecting cylinder 6065 is installed on the outside of one of the scrapers 6064. A second inclined plate 6067 is installed on the outside of the connecting cylinder 6065. The second inclined plate 6067 is made of an elastic material. Telescopic column 6066 is installed on the outside of another scraper 6064, and the end of the telescopic column 6066 away from the scraper 6064 is installed inside the connecting cylinder 6065.

[0032] The working process of using guide component 606 to absorb debris: As the first push rod 602 controls the receiving box 605 to reciprocate horizontally, the two second springs 6063 inside the receiving box 605 begin to reciprocate within it. Driven by the two second springs 6063, the two scrapers 6064 begin to move, and the scraper bars at the top of the scrapers 6064 begin to scrape the feed chute 6062, promoting the removal of debris from the feed chute 6062. The telescopic column 6066 repeatedly moves in and out of the connecting cylinder 6065. The debris falling from the cylinder is guided by the two second inclined plates 6067 and slowly falls into the channel 6068, preventing debris from rapidly entering the channel 6068 and causing blockage inside.

[0033] By setting the guide component 606, during the process of receiving debris, the scraper at the top of the scraper 6064 scrapes the feed trough 6062, promoting the debris to leave the feed trough 6062 and enter the receiving box 605 through the feed trough 6062 or be squeezed out of the feed trough 6062 and fall onto the first adhesive strip. The debris falling from there is guided by the two second inclined plates 6067 and slowly falls into the channel 6068, avoiding the debris from entering the channel 6068 quickly and causing blockage inside the channel 6068.

[0034] The grinding mechanism 8 also includes: The movable frame 801 is slidably connected to the outside of the first slide rail 7; The second slide rail 802 is located above the movable frame 801, and the second indexing table 803 is slidably connected to the outside of the second slide rail 802.

[0035] When adjusting the position of the second indexing table 803 on the first slide rail 7 and the second slide rail 802, the ball screw is driven by a servo motor to move, and the ball screw drives the movement of the moving frame 801 or the second indexing table 803, thereby adjusting the position of the grinding wheel 804.

[0036] By setting the first indexing table 3 and the second indexing table 803, the workpiece and the grinding wheel 804 are precisely rotated to the specified angular position and locked, aligning the grinding wheel 804 with the workpiece. This allows for grinding operations at specified angles on the workpiece without requiring manual adjustment of the grinding wheel 804 or workpiece angle during grinding. Furthermore, the distance between the second indexing table 803 and the first indexing table 3 is easily adjustable, facilitating workpiece disassembly.

[0037] Working principle: Before using the equipment, adjust the first indexing table 3 to adjust the angle of the gripper 4 to complete the material loading. According to the grinding requirements, adjust the second indexing table 803 to select the corresponding grinding wheel 804.

[0038] When adjusting the position of the second indexing table 803 on the first slide rail 7 and the second slide rail 802, the ball screw is driven by a servo motor to move, and the screw drives the movement of the moving frame 801 or the second indexing table 803, thereby adjusting the position of the grinding wheel 804. The first indexing table 3 and the second indexing table 803 work together to complete the grinding of the material.

[0039] Depending on the size of the grinding wheel 804 used, select one or two base boxes 604, and adjust the length of the adjusting rod between the two slide plates 601 according to the number of base boxes 604 to separate or fit the two base boxes 604 together. Then adjust the stroke of the electric push rod in the connecting frame 5, thereby adjusting the positions of the slide plate 601, the first push rod 602, the second push rod 603, the base box 604, and the receiving box 605. Then adjust the stroke of the second push rod 603, which will drive the base box 604 and the receiving box 605 to move upward.

[0040] Turn on the external exhaust fan to exhaust mode. The gas carries the debris through the receiving box 605 and is drawn into the first connecting pipe 611 or the second connecting pipe 614, and then into the bottom box 604 through the first connecting pipe 611 or the second connecting pipe 614.

[0041] Adjusting the first push rod 602 to reciprocating motion mode causes the second push rod 603, the base box 604, and the receiving box 605 to reciprocate horizontally below the grinding wheel 804 and the material, thereby driving the guide assembly 606 to reciprocate horizontally. Simultaneously with the movement of the base box 604, the first spring 615 and the first fixed ball 617 within the base box 604 begin reciprocating horizontally. The first fixed ball 617 repeatedly impacts the first connecting pipe 611 and the second connecting pipe 614, promoting the falling of debris from the first connecting pipe 611 and the second connecting pipe 614 into the base box 604, further promoting the adhesion of the debris to the second adhesive strip within the base box 604.

[0042] As the first push rod 602 controls the receiving box 605 to reciprocate horizontally, the two second springs 6063 inside the receiving box 605 begin to reciprocate within it. Driven by the two second springs 6063, the two scrapers 6064 begin to move, and the scraper bars at the top of the scrapers 6064 begin to scrape the feed chute 6062, promoting the removal of debris from the feed chute 6062. The telescopic column 6066 repeatedly moves in and out of the connecting cylinder 6065. The debris falling from the cylinder is guided by the two second inclined plates 6067 and slowly falls into the channel 6068, preventing debris from rapidly entering the channel 6068 and causing blockage inside.

[0043] As the bottom box 604 moves, some debris falls onto the first arc-shaped cover plate 608 and adheres to the first adhesive strip on the first arc-shaped cover plate 608.

[0044] During the grinding process, the receiving mechanism 6 is always located at the bottom of the grinding wheel 804 and the material to handle the falling debris.

[0045] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
