[0005] The purpose of this invention is to provide a bolt cleaning device and cleaning method, in which bolts can be cleaned one by one in each of the separate cavities, resulting in a good cleaning effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bolt cleaning device, comprising:

The active rod is located above the limiting push rod. The lower end of the active rod is provided with an active inclined surface. After the vertical moving mechanism drives the cleaning frame to move out of the cleaning box, the active inclined surface contacts the driven inclined surface. After continuing to move upward, the active inclined surface pushes the driven inclined surface to move the limiting rod out of the limiting groove. At this time, the limiting device is in the unlocked state.

Then, the rotation mechanism drives the cleaning frame located in the partition chamber to rotate.

[0030] S5. Perform step S4 on each of the separate cavities.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] (1) When the bolts need to be cleaned, the cleaning frame is installed on the vertical moving bracket. Then the horizontal moving mechanism moves the horizontal moving bracket to the top of the first partition chamber. Then the vertical moving mechanism moves the vertical moving bracket downward to move the cleaning frame into the cleaning fluid of the first partition chamber below. The cleaning fluid enters the installation chamber through the cleaning hole for the first cleaning. Then the vertical moving mechanism moves the vertical moving bracket upward to move the cleaning frame to the top of the cleaning box. Then the horizontal moving mechanism moves the horizontal moving bracket to the top of the second partition chamber. Then the vertical moving mechanism moves the vertical moving bracket downward to move the cleaning frame into the cleaning fluid of the second partition chamber for the second cleaning. This process continues until the cleaning frame enters the cleaning fluid of the last partition chamber. The bolts in the cleaning frame are already relatively clean. The cleaning fluid in the last partition chamber is also relatively clean even after multiple cleanings. Therefore, the bolts are also very clean after being cleaned by the cleaning fluid in the last partition chamber.

[0033] (2) The rotating mechanism can drive the cleaning frame to rotate. When the cleaning frame rotates, the bolts inside will roll, thus making more full contact with the cleaning liquid and improving the cleaning effect.

[0034] (3) After the vertical movement mechanism moves the cleaning frame out of the cleaning box, the active inclined surface contacts the driven inclined surface. After moving upward, the active inclined surface pushes the driven inclined surface to move the limit rod out of the limit groove. At this time, the limit device is in the unlocked state. The cleaning frame can be freely removed or placed without manual control of the limit rod, making the operation more convenient. Attached Figure Description

Detailed Implementation

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see Figures 1-13 This invention provides a technical solution for a bolt cleaning device.

[0051] A bolt cleaning device, comprising:

[0052] The cleaning chamber 1 has an upward-facing cleaning cavity. Several partitions 2 are fixed inside the cleaning cavity, which divides the cleaning cavity into several partitioned cavities 3. The cleaning fluid is loaded into the partitioned cavities 3.

[0053] A transverse movement mechanism is installed on the cleaning chamber 1;

[0054] The transverse support 4 is fixed on the transverse mechanism, which is used to drive the transverse support 4 to move above the cleaning tank 1.

[0055] The vertical movement mechanism is fixed on the horizontal movement bracket 4.

[0056] Vertical moving bracket 7 is fixed on vertical moving mechanism, which is used to drive vertical moving bracket 7 to move up and down.

[0057] The cleaning frame 33 has an installation cavity inside, and a cleaning hole 37 is provided on the outer wall of the installation cavity. The bolt to be cleaned is installed in the installation cavity. The cleaning frame 33 is detachably connected to the vertical moving bracket 7. The vertical moving mechanism drives the cleaning frame 33 to move into or out of the cleaning fluid.

[0058] When the bolts need cleaning, they can be inserted into the cleaning frame 33, and then the cleaning frame 33 is installed on the vertical moving bracket 7. The horizontal moving mechanism moves the horizontal moving bracket 4 to the top of the first partition chamber 3. Then, the vertical moving mechanism moves the vertical moving bracket 7 downward, moving the cleaning frame 33 into the cleaning fluid of the first partition chamber 3 below. The cleaning fluid enters the installation cavity through the cleaning hole 37 for the first cleaning. Next, the vertical moving mechanism moves the vertical moving bracket 7 upward, moving the cleaning frame 33 to the top of the cleaning box 1. Then, the horizontal moving mechanism moves the horizontal moving bracket 4 to the top of the second partition chamber 3. Then, the vertical moving mechanism moves the vertical moving bracket 7 downward, moving the cleaning frame 33 into the cleaning fluid of the second partition chamber 3 for the second cleaning. This process continues until the cleaning frame 33 enters the cleaning fluid of the last partition chamber 3. The bolts in the cleaning frame 33 are already relatively clean, and the cleaning fluid in the last partition chamber 3 remains relatively clean even after multiple cleanings. Therefore, the bolts are also very clean after being cleaned by the cleaning fluid in the last partition chamber 3. The bolts are cleaned one by one in each compartment 3, resulting in a good cleaning effect. Furthermore, while cleaning is being done in one compartment 3, the cleaning fluid in the other compartments 3 can be replaced promptly without shutting down the machine.

[0059] The vertical moving bracket 7 includes two vertical moving parallel rods 8 and a vertical moving crossbar 9 fixed between the two vertical moving parallel rods 8. The vertical moving crossbar 9 is fixed on the vertical moving mechanism, and the two ends of the cleaning frame 33 are detachably connected to the lower ends of the two parallel rods.

[0060] To enhance the cleaning effect: a rotating mechanism is installed on the vertical moving bracket 7. The rotating mechanism includes a rotating motor 10, an upper rotating long shaft 11, two lower rotating short shafts 12, four synchronous pulleys 13, and two synchronous belts 14. Each of the two vertical moving parallel rods 8 is provided with a vertical moving mounting groove 15. The upper rotating long shaft 11 is rotatably connected between the two vertical moving parallel rods 8. The two lower rotating short shafts 12 are rotatably connected in the two vertical moving mounting grooves 15 respectively. The four synchronous pulleys 13 are fixed at both ends of the upper rotating long shaft 11 and on the two lower rotating short shafts 12 respectively. The four synchronous belts 14 are all located in the corresponding vertical moving mounting grooves 15. The two synchronous belts 14 are respectively installed between the two synchronous belts 14 installed in the same vertical moving mounting groove 15. The rotating motor 10 is fixed on the vertical moving bracket 7. The rotating shaft of the rotating motor 10 is fixedly connected to the upper rotating long shaft 11. The two ends of the cleaning frame 33 are detachably connected to the two lower rotating short shafts 12.

[0061] When the vertical movement mechanism moves the vertical movement bracket 7 downwards, it moves the cleaning frame 33 into the cleaning fluid in the partition chamber 3. Then, the rotating motor 10 drives the upper rotating shaft 11 to rotate. The two synchronous pulleys 13 fixed on the upper rotating shaft 11 also rotate accordingly. These two synchronous pulleys 13 drive two other synchronous pulleys 13 to rotate via the synchronous belt 14, thereby driving the two lower rotating shafts 12 to rotate. The two lower rotating shafts 12 then drive the cleaning frame 33 to rotate. When the cleaning frame 33 rotates, the bolts inside will roll, thus making more thorough contact with the cleaning fluid and improving the cleaning effect. Of course, the vertical movement mechanism can also sway up and down during rotation to further enhance the cleaning effect.

[0062] The following is a detachable method between the cleaning frame 33 and the two downward rotating short shafts 12.

[0063] A mounting bracket 16 is fixed at one end of the lower rotating short shaft 12 near the cleaning frame 33. The mounting bracket 16 is provided with a mounting groove 17. Mounting protrusions 18 are fixed at both ends of the cleaning frame 33. The two mounting protrusions 18 are respectively installed in the two mounting grooves 17. The mounting bracket 16 is also provided with a limiting device for limiting the mounting protrusions 18.

[0064] The limiting device includes a limiting rod 19 and a limiting spring 20. A limiting groove 21 is provided on the side wall of the mounting groove 17. The limiting rod 19 is installed in the limiting groove 21, and the limiting spring 20 is positioned between the bottom surfaces of the limiting rod 19 and the limiting groove 21. A limiting groove 22 is provided on the mounting protrusion 18. When the limiting rod 19 is inserted into the limiting groove 22, the limiting spring 20 is in its original length state. At this time, the limiting rod 19 limits the mounting protrusion 18, thereby restricting the cleaning frame 33 between the two lower rotating short shafts 12. When it is necessary to remove the cleaning frame 33 from the two lower rotating short shafts 12, simply push the limiting rod 19 into the limiting groove 21, causing the limiting rod 19 to leave the limiting groove 22. At this time, the limiting spring 20 is in a compressed state, and the cleaning frame 33 can be removed.

[0065] To facilitate the disassembly and installation of the cleaning frame 33, the limiting device also includes a limiting push rod 23. A side connecting groove 24 is provided on the side wall of the limiting slide groove 21. One end of the limiting push rod 23 is fixedly connected to the limiting rod 19, and the other end extends out of the side connecting groove 24. A driven inclined surface 25 is provided at one end of the limiting push rod 23 extending out of the side connecting groove 24. An active rod 26 is fixed on the transverse support 4. The active rod 26 is positioned above the limiting push rod 23, and an active inclined surface 27 is provided at the lower end of the active rod 26. After the vertical movement mechanism moves the cleaning frame 33 out of the cleaning box 1, the active inclined surface 27 contacts the driven inclined surface 25. Continuing to move upwards, the active inclined surface 27 pushes the driven inclined surface 25, causing the limiting rod 19 to move out of the limiting groove 22. At this time, the limiting device is in the unlocked state (e.g., ...). Figure 9As shown), the cleaning frame 33 can be freely removed or placed without manual control of the limiting rod 19. When the mounting protrusion 18 of the cleaning frame 33 to be cleaned is installed in the corresponding mounting groove 17 (the initial opening of the mounting groove 17 faces upward), the vertical movement mechanism drives the vertical movement bracket 7 to move downward. When the driven inclined surface 25 completely leaves the active inclined surface 27, it receives the rebound force of the limiting spring 20. The limiting rod 19 has been inserted into the limiting groove 22, completing the installation of the cleaning frame 33, which is very convenient.

[0066] The following is one implementation of the vertical movement mechanism.

[0067] The vertical movement mechanism includes two vertical movement bases 28 and a vertical movement connecting seat 29 fixed between the two vertical movement bases 28. A vertical movement screw 30 is rotatably connected between the two vertical movement bases 28. A vertical movement nut 31 is threaded onto the vertical movement screw 30. The vertical movement nut 31 is fixedly connected to the vertical movement bracket 7. A vertical movement motor 32 is fixed on the upper vertical movement base 28. The rotating shaft of the vertical movement motor 32 is fixedly connected to the vertical movement screw 30.

[0068] The rotation of the vertical movement motor 32 can drive the vertical movement nut 31 to move up and down, thereby driving the vertical movement bracket 7 to move up and down.

[0069] The cleaning frame 33 includes a cleaning cylinder 35. One end of the cleaning cylinder 35 is fixed with a cylinder fixing plate 34, and the other end is hinged with a cylinder opening and closing plate 36. An opening and closing bolt 38 is provided on the cylinder opening and closing plate 36. The cleaning cylinder 35 is provided with an opening and closing threaded hole 39. When the opening and closing bolt 38 is threadedly connected to the opening and closing threaded hole 39, the cylinder opening and closing plate 36 closes the opening of the cleaning cylinder 35.

[0070] By unscrewing the opening and closing bolt 38, the bolts that need to be cleaned can be inserted into the cleaning cylinder 35. After insertion, the opening and closing bolt 38 can be screwed back on.

[0071] Furthermore, the lateral movement mechanism includes:

[0072] Two left transverse supports 40 are fixed on the left side of the cleaning box 1. A left fixed shaft 41 is fixed between the two left transverse supports 40. A left slider 44 is sleeved on the left fixed shaft 41.

[0073] Two right transverse support brackets 42 are fixed on the right side of the cleaning tank 1. A transverse screw 43 is rotatably connected between the two right transverse support brackets 42. A transverse nut 45 is threaded onto the transverse screw 43.

[0074] The transverse support 4 includes two transverse parallel rods 5 and a transverse crossbar 6 fixed between the two transverse parallel rods 5. The ends of the two transverse parallel rods 5 away from the transverse crossbar 6 are respectively fixedly connected to the left slider 44 and the transverse nut 45.

[0075] A transverse motor 46 is fixed on the outer wall of the cleaning tank 1. A transverse drive pulley 47 is fixed on the shaft of the transverse motor 46. A transverse driven pulley 48 is fixed on the transverse screw 43. A transverse connecting belt 49 connects the transverse drive pulley 47 and the transverse driven pulley 48.

[0076] The transverse motor 46 can drive the transverse screw 43 to rotate, thereby causing the transverse nut 45 to move laterally. The movement of the transverse nut 45 drives the left slider 44 to move relative to the left fixed shaft 41 through the transverse bracket 4, resulting in good stability of movement.

[0077] A cleaning method based on the aforementioned bolt cleaning device was also disclosed:

[0078] S1, the vertical movement mechanism drives the vertical movement bracket 7 to move upward, the active inclined plane 27 pushes the driven inclined plane 25 to make the limit rod 19 move out of the limit groove 22, and the limit device is in the unlocked state;

[0079] S2. Install the two mounting protrusions 18 on the cleaning frame 33 containing the bolts to be cleaned into the two mounting slots 17 respectively.

[0080] S3. The vertical movement mechanism drives the vertical movement bracket 7 to move downward, and the limiting rod 19 is inserted into the limiting groove 22.

[0081] S4. After the horizontal movement mechanism moves the cleaning frame 33 above the partition cavity 3, the vertical movement mechanism moves the cleaning frame 33 into the cleaning fluid of the corresponding partition cavity 3. Then, the rotation mechanism drives the cleaning frame 33 located in the partition cavity 3 to rotate.

[0082] S5. Perform step S4 on each of the separate cavities 3.
