[0002] In the end face machining of bolts, a custom track is usually customized according to the bolt specifications to achieve automatic bolt feeding. A fixture is also required between the custom track and the end face cutting equipment to clamp the bolt to be machined.

[0003] An existing patent (publication number: CN209189877U) discloses a bolt end-face processing assembly, including a mounting body with a support, a mounting cavity between the support and the mounting body, a pushing mechanism slidably mounted on the mounting body within the mounting cavity, and an end-face processing device slidably mounted on the mounting body downstream of the pushing mechanism, the sliding direction of the end-face processing device being perpendicular to the sliding direction of the pushing mechanism; a bolt guiding mechanism communicating with the mounting cavity is provided on the support, and a clamping mechanism is provided on the mounting body between the bolt guiding mechanism and the end-face processing device; the pushing mechanism is provided with a top-loading mechanism. This assembly achieves mechanized guiding, pushing, clamping, positioning, and top-loading of bolts after processing, significantly reducing operational safety hazards during bolt clamping and effectively reducing the labor intensity of workers; it also greatly improves work continuity and efficiency. Furthermore, this bolt end-face processing assembly is small in size and low in cost.

[0004] In implementing this solution, the inventors found that each bolt feeding mechanism and clamping mechanism can complete the feeding and clamping of a single bolt. To improve the efficiency of bolt end milling, the clamping assembly was redesigned, and a single clamping moving seat was used to fix multiple bolts before processing, effectively improving the efficiency of bolt processing.

[0044] See attached document Figure 1-8This utility model provides a bolt end face processing machine, including a machine base 1. The front left and right sides of the machine base 1 are detachably snapped to the rear left and right sides of the positioning frame 6. A lower limit plate 61 is fixedly provided on the top rear side of the positioning frame 6. An auxiliary frame 8 is fixedly provided on the top of the positioning frame 6. An installation frame 81 is fixedly provided on the top of the auxiliary frame 8. A lifting cylinder 82 is fixedly provided on the bottom of the installation frame 81. An installation plate 85 is movably connected to the bottom of the lifting cylinder 82. An upper limit plate 9 is detachably snapped to the bottom of the installation plate 85.

[0045] In this embodiment, a drive motor 11 is fixedly installed in the middle left side of the base 1, and a lead screw 12 is fixedly installed at the output end of the drive motor 11 on the right side. The left and right ends of the lead screw 12 are movably connected to the left and right ends of the middle part of the base 1, respectively. A first guide rail 13 is fixedly installed on the front and rear sides of the top of the base 1.

[0046] A stop cylinder 14 is detachably snapped onto the front right side of the base 1. A clamping plate 15 is fixed at the bottom output end of the stop cylinder 14. A feeding guide rail 5 is detachably snapped onto the front right side of the base 1. The left end of the guide rail, the discharge side, cooperates with the bottom of the clamping plate 15.

[0047] The drive motor 11 drives the lead screw 12 to rotate. The lead screw 12 cooperates with the nut seat 22 to move the motor frame 2 left and right above the machine base 1, completing the working position adjustment of the cutter head 44. The first guide rail 13 cooperates with the first slide 21 to improve the sliding stability of the machine frame 2 above the machine base 1.

[0048] The shut-off cylinder 14 cooperates with the clamping plate 15 to cut off and release the bolts output from the left end of the feeding guide rail 5, preventing too many bolts from entering between the lower limit plate 61 and the upper limit plate 9.

[0049] In this embodiment, the top of the base 1 is slidably connected to the frame 2, and the bottom of the frame 2 is fixedly connected to the first slide block 21 by bolts. The front and rear ends of the first slide block 21 are slidably connected to the outer sides of the two first guide rails 13 respectively. The bottom of the first slide block 21 is fixedly provided with a nut seat 22, and the middle part of the nut seat 22 is threadedly connected to the outer side of the lead screw 12. The bottom of the first slide block 21 is slidably connected to the top of the base 1.

[0050] A milling motor 3 and a support base 4 are fixedly mounted on the top and middle of the frame 2, respectively. A first pulley 31 is fixedly mounted on the rear output end of the milling motor 3. A rotating shaft 41 is movably connected to the middle of the support base 4. A second pulley 42 is fixedly mounted on the rear end of the rotating shaft 41. The outer side of the second pulley 42 is connected to the outer side of the first pulley 31 via belt drive. A tool holder 43 is detachably snapped onto the front end of the rotating shaft 41. A tool head 44 is detachably snapped onto the front end of the tool holder 43.

[0051] The milling motor 3 drives the rotating shaft 41 to rotate via the first pulley 31 and the second pulley 42. The rotating shaft 41 drives the tool holder 43 and the tool head 44 to rotate, which can perform milling operations on the bolts clamped between the lower limit plate 61 and the upper limit plate 9.

[0052] In this embodiment, a reset cylinder 62 is fixedly installed at the bottom front end of the positioning frame 6, and a second slide block 63 is fixedly installed at the rear output end of the reset cylinder 62. A second guide rail 64 is fixedly installed on both the left and right sides of the bottom of the positioning frame 6, and the top left and right sides of the second slide block 63 are slidably connected to the bottom of the two second guide rails 64 respectively.

[0053] The deflection cylinder 7 is detachably snapped into the middle of the second slide block 63. A retainer 71 is fixedly provided at the rear output end of the deflection cylinder 7. A buffer rubber 72 is fixedly provided on the outer side of the retainer 71. The bottom of the buffer rubber 72 abuts against the rear side of the lower limit plate 61, and the top of the buffer rubber 72 abuts against the rear side of the upper limit plate 9.

[0054] The reset cylinder 62 drives the second slide block 63 to slide on the second guide rail 64, changing the working position of the deflection cylinder 7 below the positioning frame 6. After the deflection cylinder 7 completes the adjustment of the working position of the card seat 71 and the buffer rubber 72, the buffer rubber 72 is pressed against the screw head of the bolt held between the upper limit plate 9 and the lower limit plate 61, ensuring that the screw head and the end face of the bolt connection are in contact with the rear side of the lower limit plate 61 and the upper limit plate 9, which facilitates the milling operation of the cutter head 44 on the screw head end face of multiple bolts and improves the milling operation efficiency of the bolt end face.

[0055] In this embodiment, a left-side cylinder 83 and a right-side cylinder 84 are movably connected to the left and right sides of the mounting bracket 81, respectively. The bottom output end of the left-side cylinder 83 is movably connected to the left end of the mounting plate 85, and the bottom output end of the right-side cylinder 84 is movably connected to the right end of the mounting plate 85.

[0056] The left-side cylinder 83 and the right-side cylinder 84 work together to tilt the mounting plate 85, which is movably mounted below the lifting cylinder 82.

[0057] When the bolt at feed guide 5 needs to be fed between the lower limit plate 61 and the upper limit plate 9, the left cylinder 83 needs to extend and the right cylinder 84 needs to retract. At this time, the lifting cylinder 82 needs to raise the working height of the upper limit plate 9 to complete the left-low and right-high setting of the upper limit plate 9. At this time, the gap between the upper limit plate 9 and the left side of the lower limit plate 61 is smaller than the outer diameter of the bolt, so as to prevent the bolt to be processed released from feed guide 5 from falling off the lower limit plate 61.

[0058] When clamping and fixing the bolts on the lower limit plate 61, the lifting cylinder 82 needs to lower the working height of the upper limit plate 9. At this time, the left cylinder 83 retracts and the right cylinder 84 extends to level the upper limit plate 9, so that the leveled upper limit plate 9 can clamp and fix the bolts on the lower limit plate 61.

[0059] When unloading the bolts that have undergone end milling on the lower limit plate 61, the left cylinder 83 needs to retract and the right cylinder 84 needs to extend. At this time, the lifting cylinder 82 needs to raise the working height of the upper limit plate 9 so that the right end of the upper limit plate 9 can push the screw on the lower limit plate 61 from right to left to complete the bolt unloading operation.

[0060] In this embodiment, the right side of the lower limit plate 61 extends to the left outlet of the feeding guide rail 5.

[0061] The lower limit plate 61 cooperates with the feeding guide rail 5 to facilitate the smooth rolling of the bolts released by the clamping plate 15 and the stop cylinder 14 on the feeding guide rail 5 onto the lower limit plate 61.

[0062] In this embodiment, the bottom of the upper limit plate 9 is fixed with multiple curved limiting grooves 91 at equal intervals.

[0063] The curved limiting groove 91 on the upper limit plate 9 performs partitioned clamping of the bolts on the lower limit plate 61. When fixing the bolts on the lower limit plate 61, the lifting cylinder 82 completes the adjustment of the working position of the upper limit plate 9 on the lower limit plate 61. The left cylinder 83 and the right cylinder 84 work together to push the left and right ends of the upper limit plate 9, so as to satisfy the stable clamping of multiple bolts by the upper limit plate 9 and the lower limit plate 61.

[0064] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
