Description

Technical Field

[0001] This invention relates to the field of moving blade assembly technology for shredders, and more specifically to a moving blade bolt and nut assembly device. Background Technology

[0002] The chopper's moving blade shaft has multiple mounting seats distributed on its side, each housing a moving blade. During assembly, hexagonal bolts are passed sequentially through the bolt holes on the pressure plate, moving blade, and mounting seats. A hexagonal lock nut is then tightened onto the bolt, creating a pre-loose fit. Because the mounting seats are U-shaped and the gap between the side walls and the nut is very small (theoretically between 4.5 and 6 mm), manual installation is not convenient. The operator must hold the hexagonal lock nut with one hand and support the hexagonal bolt head with the other, slowly tightening the lock nut onto the bolt. After all the loosening is complete, thread-locking adhesive is applied to the threads of the hexagonal lock nut and hexagonal bolt. Finally, an electric or pneumatic wrench is used to tighten the hexagonal lock nut, thus securing the moving blade to the mounting seat and completing the moving blade assembly.

[0003] It is evident that traditional assembly methods require manual handling of nuts, individual loosening and tightening, etc., which is time-consuming. Nuts cannot be automatically supplied, resulting in high labor intensity for operators and affecting the assembly efficiency of the moving blade assembly process, thereby restricting the overall assembly efficiency of the shredder. Summary of the Invention

[0004] The technical problem to be solved by this invention is: how to improve the assembly efficiency of bolts and nuts on the moving tool mounting base.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0006] The present invention provides a moving bolt and nut assembly device, including a posture retainer, a nut pusher on one side of the posture retainer, a rotation power unit on the other side of the posture retainer, a vertical retaining channel inside the posture retainer, and the nut pusher and the rotation power unit respectively facing the bottom opposite sides of the vertical retaining channel.

[0007] The beneficial effects of this invention are:

[0008] Using this invention, the moving nut simply needs to enter from the top of the vertical retaining channel, then be pushed by the nut pusher, and driven by the rotary power unit to assemble the moving bolt nut. This simplifies operation, improves assembly efficiency, and significantly reduces labor intensity. Specifically, by matching the size and shape of the vertical retaining channel to the moving nut, the nut can slide downwards in a vertical position. Furthermore, the number of vertical retaining channels can be set to one or more, allowing for the simultaneous assembly of a corresponding number of moving nuts.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the rotary power unit includes a rotary power block and a compressed air valve. The rotary power block has an airflow channel and an impeller cavity. The impeller cavity has a rotatable rotary impeller. The center of the rotary impeller has a through hole that matches the shape of the moving knife nut. The center of the rotary impeller is directly opposite to and connected to the bottom side of the vertical holding channel. The inlet end of the compressed air valve can be used to connect to a compressed air source. The outlet end of the compressed air valve is connected to the airflow channel. The outlet end of the airflow channel is connected to the impeller cavity. The airflow in the airflow channel can drive the rotary impeller to rotate.

[0011] When the air inlet of the compressed air valve is connected to a compressed air source, simply opening the compressed air valve will generate airflow in the airflow channel, which will then cause the rotating impeller to rotate. The rotating impeller will drive the moving blade nut to rotate, thereby realizing the assembly of the moving blade nut. The time and duration of the rotational power generation can be controlled at will, making operation convenient.

[0012] Furthermore, an exhaust port is provided on the side wall of the impeller cavity.

[0013] It facilitates the discharge of compressed gas, maintains gas flow, and ensures the rotational power of the impeller.

[0014] Furthermore, the number of impeller cavities is the same as the number of vertical holding channels, and each impeller cavity corresponds to and faces the bottom side of a vertical holding channel.

[0015] The number of impeller chambers and the number of vertical retaining channels can be one or two or more, corresponding to the number of moving tool nuts required on each moving tool mounting seat. This facilitates the assembly of multiple moving tool nuts on a single moving tool mounting seat at one time, improving assembly efficiency.

[0016] Furthermore, an auxiliary pad is provided between the rotating power block and the attitude holding frame, and the auxiliary pad has a nut channel facing the middle of the rotating impeller.

[0017] The auxiliary pad can be used to temporarily store the moving nut, which can improve assembly efficiency; at the same time, it can help to seal the side of the airflow channel, preventing too much gas from overflowing into the vertical holding channel, so that the compressed gas can be discharged in a directional manner, thus improving the operating environment.

[0018] Furthermore, the rotating power block is provided with an end cap on the side opposite to the attitude retainer, and the end cap is provided with a through hole through which the moving knife nut can pass.

[0019] It facilitates the sealing of the sides of the airflow channel, preventing excessive gas leakage and avoiding energy waste.

[0020] Furthermore, the rotating power unit is provided with an independently arranged bolt fastener on the side away from the attitude retainer. The bolt fastener has a fixing hole that matches the head shape of the moving tool bolt. The number of fixing holes is the same as the number of vertical retaining channels, and each fixing hole corresponds to and faces the bottom side of a vertical retaining channel. A handheld structure is provided on one side of the bolt fastener.

[0021] When assembling the moving tool nut, it is easy to hold the bolt fixing component to fix the moving tool bolt, prevent the moving tool bolt from moving, facilitate fastening assembly, and has good stability.

[0022] Furthermore, the attitude retainer is connected to the rotational power unit by bolts; the attitude retainer is provided with end plates on both the side facing the rotational power unit and the side away from the rotational power unit.

[0023] It has good overall integrity and is easy to disassemble and assemble. Different vertical holding channel specifications of posture holding frame can be replaced according to the usage environment. The vertical holding channel can be processed into a barrel groove through the end plate, and the two sides are closed by the end plate, which is convenient to process.

[0024] Furthermore, the nut pusher is provided with a cylindrical pusher boss, and the end of the pusher boss is provided with a cylindrical positioning post; the number of pusher bosses is the same as the number of vertical holding channels, and each pusher boss corresponds to and faces the bottom side of a vertical holding channel.

[0025] The positioning pin can be inserted into the center of the moving tool nut for positioning, preventing the moving tool nut from tilting and keeping the moving tool nut moving forward smoothly. The pushing boss can push the moving tool nut axially. There can be one or two or more pushing bosses and positioning pins, which facilitates pushing all the moving tool nuts required for the moving tool mounting seat at one time, improving assembly efficiency.

[0026] Furthermore, the top of the attitude holding frame is also connected to a flexible conveying track, which has a rectangular cross-section and a nut supply unit at its top; the lower end of the flexible conveying track is directly opposite the upper end of the vertical holding channel.

[0027] The rectangular flexible conveyor track allows the moving nut from the nut supply unit to be conveyed vertically downwards and finally enters the vertical holding channel, which facilitates automatic supply of the moving nut and improves assembly efficiency.

[0028] Furthermore, the flexible conveying track is in the shape of a rectangular flat spring; the number of flexible conveying tracks is the same as the number of vertical holding channels, and each flexible conveying track corresponds to and is directly opposite the upper end of a vertical holding channel.

[0029] The rectangular flat spring has a certain degree of flexibility and adaptability, is lightweight, and has good vibration conduction. It can make the moving knife nut fall smoothly through vibration and avoid jamming. There can be one or two or more flexible conveyor tracks to facilitate the simultaneous conveying of the required number of moving knife nuts.

[0030] Furthermore, the nut supply unit includes a cantilever conveying track and a vibratory plate. One end of the cantilever conveying track is connected to the top of the flexible conveying track, and the other end of the cantilever conveying track is connected to the vibratory plate. A support frame is provided below the vibratory plate.

[0031] Initially, the moving nut can be randomly inserted into the vibratory feeder. The vibratory feeder can adjust the posture of the moving nut by vibrating. When the posture is horizontal and matches the channel shape of the cantilever conveyor track, the moving nut can enter the cantilever conveyor track and move towards its cantilever end. Finally, it can fall smoothly into the flexible conveyor track in a vertical state. This facilitates the conveying of the moving nut and is easy to operate.

[0032] Furthermore, the drive component of the vibratory feeder is electrically connected to a proximity switch, which is mounted on the attitude holding frame with its probe facing the vertical holding channel side.

[0033] The driving component of the vibratory feeder can be a transducer. The proximity switch can control the start and stop of the driving component of the vibratory feeder. The proximity switch makes it easy to keep the required number of moving knife nuts (e.g., 2-3) in the vertical holding channel, which facilitates automatic control of the feeding of the moving knife nuts, reduces labor intensity, simplifies operation, and improves assembly efficiency.

Detailed Implementation

[0043] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0044] See also: This invention Figure 2-6 .

[0045] The present invention provides a moving bolt and nut assembly device, including a posture retainer 7, a nut pusher 8 on one side of the posture retainer 7, a rotation power unit 9 on the other side of the posture retainer 7, a vertical retaining channel 70 inside the posture retainer 7, and the nut pusher 8 and the rotation power unit 9 respectively facing the bottom opposite sides of the vertical retaining channel 70.

[0046] principle:

[0047] In use, one side of the rotary power unit 9 faces the moving tool mounting base 2. The moving tool bolt 3 passes through the pressure plate 5 and the moving tool body 6 before entering the rotary power unit 9. The moving tool nut 4 enters from the top of the vertical holding channel 70. The vertical holding channel 70 can be rectangular and can be machined to match the size of the moving tool nut 4 of a specific specification, so that the moving tool nut 4 remains vertical (horizontal axis) and slides down within the vertical holding channel 70. After sliding to the bottom, the moving tool nut 4 can be pushed into the rotary power unit 9 by manually controlling the nut pusher 8. Finally, the rotary power unit 9 is activated, so that the moving tool nut 4 generates rotational power and tightens onto the moving tool bolt 3.

[0048] In summary, by employing this invention, the assembly of the movable bolt nut can be achieved simply by having the movable nut 4 enter from the top of the vertical holding channel 70, then pushed by the nut pusher 8, and driven by the rotary power unit 9. This simplifies the operation, improves assembly efficiency, and significantly reduces labor intensity. Specifically, by matching the size and shape of the vertical holding channel 70 with the movable nut 4, the nut can slide downwards in a vertical posture. Furthermore, the number of vertical holding channels 70 can be set to one or more, allowing for the simultaneous assembly of a corresponding number of movable nuts 4.

[0049] Furthermore, such as Figure 3-4 As shown: The rotary power unit 9 includes a rotary power block 90 and a compressed air valve 91. The rotary power block 90 is provided with an airflow channel 92 and an impeller cavity 93. The impeller cavity 93 is provided with a rotatable rotary impeller 94. The middle part of the rotary impeller 94 is a through hole that matches the shape of the movable knife nut 4. The middle part of the rotary impeller 94 is directly opposite to and connected to the bottom side of the vertical holding channel 70. The air inlet end of the compressed air valve 91 can be used to connect to a compressed air source. The air outlet end of the compressed air valve 91 is connected to the airflow channel 92. The air outlet end of the airflow channel 92 is connected to the impeller cavity 93. The airflow in the airflow channel 92 can drive the rotary impeller 94 to rotate.

[0050] Preferably, the air outlet of the airflow channel 92 can be arranged tangentially along the outer periphery of the rotating impeller 94, so that the airflow in the airflow channel 92 can drive the rotating impeller 94 to rotate, making full use of the airflow power. The compressed gas in the impeller cavity 93 can be discharged through the gaps on both sides of the rotating power block 90 to maintain the gas flow state.

[0051] When the air inlet of the compressed air valve 91 is connected to a compressed air source, simply opening the compressed air valve 91 will generate airflow in the airflow channel 92, thereby causing the rotating impeller 94 to rotate. The rotating impeller 94 drives the moving knife nut 4 to rotate, thus realizing the assembly of the moving knife nut 4. The time and duration of the rotational power generation can be controlled at will, making operation convenient.

[0052] Furthermore, an exhaust port 95 is provided on the side wall of the impeller cavity 93.

[0053] It facilitates the discharge of compressed gas, maintains the gas flow state, and ensures the rotational power of the rotating impeller 94.

[0054] Furthermore, the number of impeller cavities 93 is the same as the number of vertical holding channels 70, and each impeller cavity 93 corresponds to and faces the bottom side of a vertical holding channel 70.

[0055] The number of impeller chambers 93 and the number of vertical retaining channels 70 can be one or two or more, corresponding to the number of moving knife nuts 4 required on each moving knife mounting seat 2, which facilitates the assembly of multiple moving knife nuts 4 on a moving knife mounting seat 2 at one time and improves assembly efficiency.

[0056] Furthermore, an auxiliary pad 96 is provided between the rotating power block 90 and the attitude holding frame 7, and the auxiliary pad 96 has a nut channel facing the middle of the rotating impeller 94.

[0057] The auxiliary pad 96 can be used to temporarily store the moving nut 4, which can improve assembly efficiency; at the same time, it can help to close the side of the airflow channel 92, prevent more gas from overflowing into the vertical holding channel 70, and allow the compressed gas to be discharged in a directional manner, thus improving the operating environment.

[0058] Furthermore, the rotating power block 90 is provided with an end cap 97 on the side opposite to the attitude holding frame 7, and the end cap 97 is provided with a through hole through which the movable knife nut 4 can pass.

[0059] This facilitates the sealing of the sides of the airflow channel 92, preventing excessive gas leakage and energy waste.

[0060] Furthermore, such as Figure 2-3 As shown: The rotating power unit 9 is also provided with an independently arranged bolt fastener 10 on the side away from the attitude holding frame 7. The bolt fastener 10 is provided with a fixing hole that matches the head shape of the moving tool bolt 3. The number of fixing holes is the same as the number of vertical holding channels 70, and each fixing hole corresponds to and faces the bottom side of a vertical holding channel 70. A handheld structure is provided on one side of the bolt fastener 10.

[0061] Note: In addition to the above methods, the moving bolt 3 can also be fixed with tools such as wrenches.

[0062] When assembling the moving nut 4, it is easy to hold the bolt fixing part 10 to fix the moving bolt 3, prevent the moving bolt 3 from moving, facilitate fastening assembly, and has good stability.

[0063] Furthermore, the attitude holding frame 7 is connected to the rotation power unit 9 by bolts; the attitude holding frame 7 is provided with end plates 71 on both the side facing the rotation power unit 9 and the side away from the rotation power unit 9.

[0064] It has good overall integrity and is easy to disassemble and assemble. Different vertical holding channel 70 specifications of posture holding frame 7 can be replaced according to the usage environment. The vertical holding channel 70 can be processed into a barrel groove through the end plate 71, and the two sides are closed by the end plate 71, which is convenient to process.

[0065] Furthermore, such as Figure 3 As shown: The nut pusher 8 is provided with a cylindrical pusher boss 81, and the end of the pusher boss 81 is provided with a cylindrical positioning post 82; the number of pusher bosses 81 is the same as the number of vertical holding channels 70, and each pusher boss 81 corresponds to and faces the bottom side of a vertical holding channel 70.

[0066] The positioning pin 82 can be inserted into the center of the moving nut 4 for positioning, to prevent the moving nut 4 from tilting and to keep the moving nut 4 moving forward smoothly. The pushing boss 81 can push the moving nut 4 axially. There can be one or more pushing bosses 81 and positioning pins 82, which facilitates pushing the moving nut 4 required by the moving nut mounting seat 2 in one go and improves assembly efficiency.

[0067] Furthermore, such as Figure 2 , 5As shown: The top of the attitude holding frame 7 is also connected to a flexible conveying track 11. The cross-section of the flexible conveying track 11 is rectangular, and the top of the flexible conveying track 11 is provided with a nut supply unit; the lower end of the flexible conveying track 11 is directly opposite the upper end of the vertical holding channel 70.

[0068] The rectangular flexible conveying track 11 allows the moving nut 4 from the nut supply unit to be conveyed vertically downwards and finally enters the vertical holding channel 70, which facilitates automatic supply of the moving nut 4 and improves assembly efficiency.

[0069] Furthermore, such as Figure 2 As shown: the flexible conveying track 11 is in the shape of a rectangular flat spring; the number of flexible conveying tracks 11 is the same as the number of vertical holding channels 70, and each flexible conveying track 11 corresponds to and faces the upper end of a vertical holding channel 70.

[0070] The rectangular flat spring has a certain degree of flexibility and adaptability, is lightweight, and has good vibration conduction. It can make the moving knife nut 4 fall smoothly through vibration and avoid jamming. The flexible conveying track 11 can be one or two or more, which can facilitate the simultaneous conveying of the required number of moving knife nuts 4.

[0071] Furthermore, such as Figure 5 As shown: The nut supply unit includes a cantilever conveying track 12 and a vibratory plate 13. One end of the cantilever conveying track 12 is connected to the top of the flexible conveying track 11, and the other end of the cantilever conveying track 12 is connected to the vibratory plate 13. A support frame 14 is provided below the vibratory plate 13.

[0072] Initially, the movable nut 4 can be randomly inserted into the vibratory feeder 13. The vibratory feeder 13 can adjust the posture of the movable nut 4 by vibrating. When the posture is horizontal and matches the channel shape of the cantilever conveying track 12, the movable nut 4 can enter the cantilever conveying track 12 and move towards its cantilever end. Finally, it can fall smoothly into the flexible conveying track 11 in a vertical state, which is convenient for conveying the movable nut 4 and is easy to operate.

[0073] Furthermore, the drive component of the vibratory feeder 13 is electrically connected to a proximity switch 15, which is mounted on the attitude holding frame 7 with its detection end facing the vertical holding channel 70.

[0074] The driving component of the vibratory feeder 13 can be a transducer. The proximity switch 15 can control the start and stop of the driving component of the vibratory feeder 13. Through the proximity switch 15, it is easy to keep the required number of moving knife nuts 4 (e.g., 2-3) in the vertical holding channel 70, so as to facilitate automatic control of the feeding of the moving knife nuts 4, reduce labor intensity, simplify operation, and improve assembly efficiency.
