Description

Technical Field

[0001] This application relates to the technical field of mechanical processing assistance, and particularly to a fixture for automatically cleaning residues in threaded holes. Background Art

[0002] In the field of mechanical processing, the cleaning of threaded holes is an important step to ensure the quality of workpieces to be cleaned and the smooth progress of subsequent assembly. Currently, the methods for cleaning metal chips and other granular debris in the threaded holes of workpieces are automatic cleaning by a cleaning machine, including using an ultrasonic water tank, or manual blowing with a compressed air gun.

[0003] Many production lines still adopt the method of manually cleaning each threaded hole with a gas gun. This method not only has low efficiency, but also easily causes problems such as missed blowing or incomplete blowing due to improper operation. The conventional method is that the operator holds the gas gun and blows air at each threaded hole. This method depends on the proficiency and concentration of the operator, and it is difficult to ensure that each hole is effectively cleaned. Any negligence or improper operation may lead to missed blowing or incomplete blowing, which in turn affects the smooth progress of subsequent processes and the assembly and use effect of the workpiece. This situation needs to be improved. Summary of the Utility Model

[0004] In order to improve efficiency while ensuring the cleaning effect of threaded holes, this application provides a fixture for automatically cleaning residues in threaded holes.

[0005] A fixture for automatically cleaning residues in threaded holes provided by this application adopts the following technical solutions:

[0006] A fixture for automatically cleaning residues in threaded holes includes:

[0007] A workbench for placing the workpiece to be cleaned;

[0008] A positioning component arranged on the workbench and used for fixing the workpiece to be cleaned;

[0009] A blowing component, the blowing component includes a first blowing unit and a second blowing unit arranged side by side, and the gap between the first blowing unit and the second blowing unit forms a sliding space for the workbench to slide;

[0010] A driving component for driving the workbench to slide in the sliding space so that the workbench moves towards one side of the first blowing unit or the second blowing unit;

[0011] When the driving component drives the workbench to move towards the side of the first air blowing unit, the first air blowing unit blows and cleans the threaded holes on the first side of the workpiece to be cleaned; when the driving component drives the workbench to move towards the side of the second air blowing unit, the second air blowing unit blows and cleans the threaded holes on the second side of the workpiece to be cleaned.

[0012] By adopting the above technical solution, the workpiece to be cleaned is fixed on the workbench through the positioning component, and the driving component drives the workbench to reciprocate within the sliding space. When the workbench moves to one side of the first air blowing unit, the first air blowing unit blows and cleans the threaded holes on the first side of the workpiece to be cleaned. When the workbench moves to one side of the second air blowing unit, the second air blowing unit blows and cleans the threaded holes on the first side of the workpiece to be cleaned. Driven by the driving component, the workbench can move within the sliding space, thereby achieving a comprehensive cleaning of the threaded holes of the workpiece. This design ensures that multiple threaded holes of the workpiece can be efficiently cleaned simultaneously, improving the convenience of operation and the cleaning effect. The solution in this application improves the efficiency while ensuring the cleaning effect of the threaded holes.

[0013] Optionally, the first air blowing unit includes a first protection plate, a first air collecting block, a first air duct, and a first air blowing needle. The first air collecting block is fixed on the side of the first protection plate away from the workbench. One end of the first air duct is fixed to the first air collecting block, and one end of the first air blowing needle is arranged on the first air duct. The other end of the first air blowing needle is located on the side of the first protection plate close to the workbench.

[0014] The first air blowing unit includes a gas collecting state and a blowing state. When the first air blowing unit is in the gas collecting state, the air flow sequentially passes through the first air blowing needle, the first air duct and enters the first air collecting block, and the first air collecting block is used to collect the air flow; when the first air blowing unit is in the blowing state, the first air blowing needle is located in the threaded hole of the workpiece to be cleaned, and the air flow flows into the threaded hole of the workpiece to be cleaned through the first air blowing needle.

[0015] By adopting the above technical solution, the first air blowing unit can effectively collect the air flow in the gas collecting state, preventing the air flow from dissipating, and in the blowing state, it can accurately send the air flow into the threaded hole of the workpiece to be cleaned, realizing the efficient cleaning of the residue inside the threaded hole. This design ensures the effective utilization of the air flow, optimizes the cleaning process, improves the overall cleaning effect and the reliability of the system. It should be noted that according to the number of threaded holes on the workpiece, design the corresponding number of first air blowing needles, and each threaded hole should be equipped with a dedicated air blowing needle to ensure that each hole can be evenly and thoroughly cleaned.

[0016] Optionally, the second air blowing unit includes a second protective plate, a second air collecting block, a second air duct, and a second air blowing needle. The second air collecting block is fixed on the side of the second protective plate away from the workbench. One end of the second air duct is fixed to the second air collecting block, one end of the second air blowing needle is disposed on the second air duct, and the other end of the second air blowing needle is located on the side of the second protective plate close to the workbench.

[0017] By adopting the above technical solution, the second air blowing unit can collect air flow in the air collecting state and send it to the second air collecting block, while in the air blowing state, the air flow is sent into the threaded hole of the workpiece to be cleaned through the second air blowing needle. This design is similar to the function of the first air blowing unit, but can be independently controlled and operated according to needs to achieve directional cleaning of different workpieces or different areas, further improving the flexibility and efficiency of cleaning.

[0018] Optionally, the positioning assembly includes a first limiting block disposed on one side of the workbench along the width direction and a second limiting block disposed on one side of the workbench along the length direction. An accommodating space for placing the workpiece to be cleaned is formed between the first limiting block and the second limiting block.

[0019] By adopting the above technical solution, by respectively arranging the first limiting block and the second limiting block on the workbench along the width direction and the length direction, the workpiece can be accurately positioned in two directions, ensuring that the workpiece does not move during the cleaning process, thereby improving the uniformity and accuracy of the cleaning effect. The positioning assembly can ensure the accurate positioning and stability of the workpiece during the entire cleaning process, further improving the overall performance and efficiency of the automatic cleaning fixture.

[0020] Optionally, the positioning assembly further includes a positioning block disposed on the workbench, and the positioning block is used to match the groove on the workpiece to be cleaned.

[0021] By adopting the above technical solution, the positioning block is designed to match the shape of the groove on the workpiece, enabling the workpiece to be accurately aligned on the workbench. This matching ensures the accuracy of the workpiece position during the cleaning process, thereby improving the accuracy of the cleaning effect. The cooperation between the positioning block and the groove can effectively prevent the workpiece from moving or rotating during the cleaning process. This stability reduces the error during the cleaning process and ensures the cleaning quality of each workpiece.

[0022] Optionally, the driving assembly includes a driving seat fixed to the workbench, a lead screw passing through the driving seat, a driving motor for driving the lead screw to rotate, and a guiding member for restricting the movement trajectory of the workbench. The driving motor is started to rotate the lead screw, and the driving seat reciprocates along the length direction of the lead screw.

[0023] By adopting the above technical solution, the driving motor realizes the precise reciprocating motion of the driving seat through the rotation of the lead screw. The guiding member is used to restrict the moving trajectory of the workbench, ensuring that the driving seat moves stably and reciprocally in the length direction of the lead screw, reducing possible lateral swing or inclination. The driving assembly can provide precise, stable and efficient motion control, ensuring that the workbench makes a smooth reciprocating motion in the length direction of the lead screw, thereby improving the performance and reliability of the entire system.

[0024] Optionally, the guiding member includes a base, a sliding seat disposed on one side of the workbench close to the base, a guide rail disposed on the base and parallel to the length direction of the lead screw, and a chute disposed on the sliding seat for the guide rail to be embedded therein, so that the sliding seat slides along the length direction of the guide rail.

[0025] By adopting the above technical solution, the sliding seat is precisely fitted with the guide rail through the chute, enabling the sliding seat to slide smoothly on the guide rail. This kind of cooperation reduces the swing or instability during movement, improves the overall stability of the system, and the guide rail is in the same length direction as the lead screw, ensuring that the sliding seat moves precisely along the predetermined trajectory and enhancing the positioning accuracy.

[0026] Optionally, a limit sensor is disposed on the base.

[0027] By adopting the above technical solution, the limit sensor can prevent the workbench from exceeding the predetermined range, protecting the equipment from damage caused by excessive movement. When the workbench reaches the limit, the sensor will send a signal to automatically stop the movement, avoiding human operation errors.

[0028] Optionally, anti-fooling devices are disposed on both the first protective plate and the second protective plate.

[0029] By adopting the above technical solution, anti-fooling devices are installed on the first protective plate and the second protective plate to ensure that the workpiece can only be assembled into the equipment in the correct way, avoiding reverse assembly, reducing rework and adjustment caused by assembly errors, and improving production efficiency.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. Fix the workpiece to be cleaned on the workbench through the positioning component. The driving component drives the workbench to reciprocate within the sliding space. When the workbench moves to one side of the first air blowing unit, the first air blowing unit blows air to clean the threaded holes on the first side of the workpiece to be cleaned. When the workbench moves to one side of the second air blowing unit, the second air blowing unit blows air to clean the threaded holes on the first side of the workpiece to be cleaned. Driven by the driving component, the workbench can move within the sliding space, thereby achieving a comprehensive cleaning of the threaded holes of the workpiece. This design ensures that multiple threaded holes of the workpiece can be efficiently cleaned simultaneously, improving the convenience of operation and the cleaning effect. The solution in this application improves the efficiency while ensuring the cleaning effect of the threaded holes.

[0044] An embodiment of the present application discloses a jig for automatically cleaning residues in a threaded hole. Referring to Figure 1 and Figure 2 , a jig for automatically cleaning residues in a threaded hole includes a workbench 1, a positioning component 2, a blowing component 3 and a driving component 4. Among them, the blowing component 3 includes a first blowing unit 5 and a second blowing unit 6. The workpiece 100 to be cleaned is fixed on the workbench 1 through the positioning component 2. Since the gap between the first blowing unit 5 and the second blowing unit 6 forms a sliding space 7, the driving component 4 drives the workbench 1 to reciprocate in the sliding space 7.

[0045] Specifically, when the workbench 1 is displaced to one side of the first blowing unit 5, the first blowing unit 5 blows and cleans the threaded hole on the first side of the workpiece 100 to be cleaned. When the workbench 1 is displaced to one side of the second blowing unit 6, the second blowing unit 6 blows and cleans the threaded hole on the first side of the workpiece 100 to be cleaned. Driven by the driving component 4, the workbench 1 can move in the sliding space 7, so as to achieve a comprehensive cleaning of the threaded hole of the workpiece.

[0046] For the convenience of understanding, the following describes the first blowing unit 5 and the second blowing unit 6:

[0047] The first blowing unit 5 includes a first protection plate 8, a first air collecting block 9, a first air duct 10 and a first blowing needle 11. The first air collecting block 9 is fixed on the side of the first protection plate 8 away from the workbench 1. One end of the first air duct 10 is fixed to the first air collecting block 9. One end of the first blowing needle 11 is fixed to the first air duct 10, and the other end of the first blowing needle 11 is located on the side of the first protection plate 8 close to the workbench 1. The second blowing unit 6 includes a second protection plate 12, a second air collecting block 13, a second air duct 14 and a second blowing needle 15. The second air collecting block 13 is fixed on the side of the second protection plate 12 away from the workbench 1. One end of the second air duct 14 is fixed to the second air collecting block 13. One end of the second blowing needle 15 is installed on the second air duct 14, and the other end of the second blowing needle 15 is located on the side of the second protection plate 12 close to the workbench 1. The second blowing unit 6 can collect air flow in the air collecting state and send it to the second air collecting block 13, as Figure 3As shown, in the blowing state, the air flow is sent into the threaded hole of the workpiece 100 to be cleaned through the second blowing needle 15. The first blowing unit 5 and the second blowing unit 6 include a gas collecting state and a blowing state. The following takes the first blowing unit 5 as an example for illustration:

[0048] When the first blowing unit 5 is in the gas collecting state, the air flow sequentially passes through the first blowing needle 11 and the first air duct 10 into the first gas collecting block 9, and the first gas collecting block 9 is used to collect the air flow; when the first blowing unit 5 is in the blowing state, the first blowing needle 11 is located in the threaded hole of the workpiece 100 to be cleaned, and the air flow flows into the threaded hole of the workpiece 100 to be cleaned through the first blowing needle 11. The first blowing unit 5 can effectively collect the air flow in the gas collecting state to prevent the air flow from dissipating, and in the blowing state, it can accurately send the air flow into the threaded hole of the workpiece 100 to be cleaned, realizing the efficient cleaning of the residues inside the threaded hole. This design ensures the effective utilization of the air flow, optimizes the cleaning process, improves the overall cleaning effect and the reliability of the system.

[0049] It should be noted that according to the number of threaded holes on the workpiece, the corresponding number of first blowing needles 11 is designed. Each threaded hole should be equipped with a dedicated blowing needle to ensure that each hole can be cleaned evenly and thoroughly. Each first blowing needle 11 has a first air duct 10. Assuming there are 18 threaded holes, then there are 18 first blowing needles 11 and 18 first air ducts 10, but there is only one first gas collecting block 9.

[0050] The gas collecting block is a device that can realize the functions of gas collection and blowing. The gas collecting block can be any one of a gas distributor, a gas switching valve, a gas flow control valve, a gas treatment unit, and a gas mixer. These devices can usually realize the functions of gas collection and blowing through mechanical control, electric control or pneumatic control. The selection of a suitable device depends on specific application requirements, the properties of the gas, the complexity of the system, and the requirements for flow rate and pressure; this application does not limit the gas collecting block, and the gas collecting block can be any device that can realize the functions of gas collection and blowing.

[0051] Refer to Figure 3, the positioning component 2 includes a first limiting block 16, a second limiting block 17 and a positioning block 19. The first limiting block 16 is fixed on one side of the workbench 1 in the width direction, and the second limiting block 17 is fixed on one side of the workbench 1 in the length direction. Precise positioning of the workpiece can be carried out in two directions, so that an accommodation space 18 for placing the workpiece 100 to be cleaned is formed between the first limiting block 16 and the second limiting block 17, ensuring that the workpiece does not move during the cleaning process, thereby improving the uniformity and accuracy of the cleaning effect; the positioning block 19 is fixed on the workbench 1, and the positioning block 19 is designed to match the shape of the groove on the workpiece, enabling the workpiece to be accurately aligned on the workbench 1. This adaptation ensures the accuracy of the workpiece position during the cleaning process. Therefore, the positioning component 2 can ensure the precise positioning and stability of the workpiece during the entire cleaning process, further improving the overall performance and efficiency of the automatic cleaning fixture.

[0052] Refer to Figure 4 and Figure 5 , the driving component 4 includes a driving seat 20, a lead screw 21, a driving motor 22 and a guiding component 23. The guiding component 23 includes a base 24, a sliding seat 25, a guide rail 26 and a chute 27. The driving seat 20 is fixed on the workbench 1, and the lead screw 21 passes through the driving seat 20, enabling the driving motor 22 to drive the driving seat 20 to reciprocate along the length direction of the lead screw 21. The sliding seat 25 is installed on one side of the workbench 1 close to the base 24. The guide rail 26 is installed on the base 24 and is parallel to the length direction of the lead screw 21. The chute 27 is opened on the sliding seat 25 for the guide rail 26 to be embedded. The sliding seat 25 is precisely fitted with the guide rail 26 through the chute 27, enabling the sliding seat 25 to slide smoothly on the guide rail 26. This cooperation reduces the swing or instability during movement and improves the overall stability of the system. Moreover, the guide rail 26 is in the same length direction as the lead screw 21, ensuring that the sliding seat 25 moves precisely along a predetermined trajectory and enhancing the positioning accuracy. Specifically, the driving motor 22 realizes the precise reciprocating motion of the driving seat 20 through the rotation of the lead screw 21, and through the cooperation of the guide rail 26 and the sliding seat 25, ensures that the driving seat 20 moves stably and reciprocally in the length direction of the lead screw 21. The driving component 4 can provide precise, stable and efficient motion control; to further ensure the safety of the sliding of the workbench 1, a limit sensor 28 is installed on the base 24. The limit sensor 28 can prevent the workbench 1 from exceeding the predetermined range and protect the equipment from damage caused by excessive movement. When the workbench 1 reaches the limit, the sensor will send a signal to automatically stop the movement, avoiding human operation errors.

[0053] As Figure 1 and Figure 2As shown in the figure, the present application has a design to prevent reverse installation. Assuming that the number of holes on both sides of the workpiece 100 to be cleaned is different, or the positions of the holes are asymmetric, if the parts are installed in reverse, the workpiece 100 to be cleaned and the air outlet needle will be damaged when starting. Therefore, anti-fooling devices 29 are installed on both the first protection plate 8 and the second protection plate 12. The anti-fooling device 29 is located on the side of the first protection plate 8 or the second protection plate 12 close to the workbench 1. Installing the anti-fooling device 29 on the first protection plate 8 and the second protection plate 12 ensures that the workpiece can only be assembled into the equipment in the correct way, avoiding reverse installation, reducing rework and adjustment caused by assembly errors, and improving production efficiency. It should be noted that the anti-fooling device 29 can use various induction switches on the market, such as: photoelectric sensors, proximity sensors, magnetic switches or laser sensors.

[0054] The implementation principle of a fixture for automatically cleaning residues in threaded holes in an embodiment of the present application is as follows: The workpiece 100 to be cleaned is fixed on the workbench 1 through the positioning component 2, and the driving component 4 drives the workbench 1 to reciprocate in the sliding space 7. When the workbench 1 moves to one side of the first air blowing unit 5, the first air blowing unit 5 blows and cleans the threaded holes on the first side of the workpiece 100 to be cleaned. When the workbench 1 moves to one side of the second air blowing unit 6, the second air blowing unit 6 blows and cleans the threaded holes on the first side of the workpiece 100 to be cleaned. Driven by the driving component 4, the workbench 1 can move in the sliding space 7, thereby realizing the comprehensive cleaning of the threaded holes of the workpiece. This design ensures that multiple threaded holes of the workpiece can be efficiently cleaned simultaneously, improving the convenience of operation and the cleaning effect. The solution in the present application improves the efficiency while ensuring the cleaning effect of the threaded holes.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
