Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing, in particular to a grinding and deburring device for bolt processing. Background Technique

[0002] In the process of bolt processing, it is necessary to first turn the thread. However, there are many burrs on the surface of the turned thread. For the screw used for transmission, such as the trapezoidal lead screw and the ball screw, the burrs on the thread surface need to be removed or polished. The current polishing method is to put the bolts into a vibrating pool containing abrasives, and make the abrasives rub against the surface of the bolts through vibration. This deburring method has low efficiency; or spray the slurry containing abrasives onto the surface of the bolts. Patent CN213411599U proposes a bolt deburring device, including a stirring mechanism and a folding mechanism. The folding mechanism includes a bottom plate, a stirring barrel, a motor and two groups of bases. The staff puts a batch of bolts and emery into the stirring barrel. The motor drives the stirring barrel to rotate. At the same time, the hydraulic oil rod pushes and pulls the left push rod, so that the stirring barrel shakes left and right while rotating, effectively enhancing the irregular movement of the bolts in the stirring barrel and enhancing the deburring effect of the bolts; according to analysis, this kind of bolt deburring device deburrs the whole bolts during work, and the deburring effect on the thread section of the bolts is poor.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment

[0023] As Figure 1 、 2 shown in and Figure 3, a deburring device for bolt processing proposed in an embodiment of the present invention, a deburring device for bolt processing, includes a workbench plate 1, and is characterized in that: the workbench plate 1 is isolated from the ground by support columns, the right side of the top surface of the workbench plate 1 is rotatably connected to a drive shaft 2, the top end of the drive shaft 2 is coaxially and fixedly connected to a centering chuck 3, the middle part of the centering chuck 3 is clamped and connected to a drive screw 4, the left side of the top surface of the workbench plate 1 is rotatably connected to a driven shaft 5, the top end of the driven shaft 5 is coaxially and fixedly connected to a quick clamp 6, the quick clamp 6 is clamped and connected to a bolt 7 to be processed, the bottom end of the drive shaft 2 is coaxially and fixedly connected to a driving synchronous pulley 8, the bottom end of the driven shaft 5 is coaxially and fixedly connected to a driven synchronous pulley 9, the driving synchronous pulley 8 and the driven synchronous pulley 9 have the same specifications, a synchronous belt 10 is wound between the driving synchronous pulley 8 and the driven synchronous pulley 9, the bottom of the right side of the workbench plate 1 is fixedly connected to a drive motor 11, and the output shaft of the drive motor 11 is fixedly connected to the driving synchronous pulley 8;

[0024] A vertical plate 12 is fixedly arranged on the back of the right side of the workbench plate 1, a lifting slide 14 is movably fitted on the front side of the vertical plate 12 through a vertical guide rail 13, a nut 15 is fixedly connected to the middle part of the lifting slide 14 through a vertically opened through hole, the nut 15 is adaptively screwed with the drive screw 4, and two horizontal conduits 16 are horizontally inserted and fixed on both sides of the lifting slide 14, and the left ends of the two horizontal conduits 16 both point to the side of the bolt 7 to be processed.

[0025] In this embodiment, the driving motor 11 drives the driving shaft 2 and the centering chuck 3 to rotate through the driving synchronous pulley 8, and then drives the driving screw 4 to rotate. At the same time, the driving synchronous pulley 8 drives the driven synchronous pulley 9 and the bolt 7 to be processed to rotate through the synchronous belt 10. Since the driving synchronous pulley 8 and the driven synchronous pulley 9 have the same specifications, the rotation speeds and directions of the driving screw 4 and the bolt 7 to be processed are the same;

[0026] Among them, the driving screw 4 and the bolt 7 to be processed have the same specifications. Therefore, when the two rotate at the same speed, the lifting slide 14 drives the two horizontal conduits 16 to move up and down uniformly along the threaded part of the bolt 7 to be processed. When the two horizontal conduits 16 eject the polishing slurry, the polishing slurry can be evenly ejected onto the threaded part of the bolt 7 to be processed and move up and down, performing targeted deburring on it, thereby improving the deburring efficiency.

[0027] In this embodiment, a polishing slurry bucket 17 is fixedly installed on the side of the workbench plate 1. Two slurry output pumps 18 are fixedly connected to the top of the polishing slurry bucket 17. The output ports of the two slurry output pumps 18 are connected to the right ends of the two horizontal conduits 16 through flexible hoses.

[0028] Among them, the polishing slurry bucket 17 contains the polishing slurry. The slurry output pump 18 pumps the polishing slurry out of the polishing slurry bucket 17, and then ejects it onto the surface of the bolt 7 to be processed through the two horizontal conduits 16. At this time, the polishing particles contained in the polishing slurry perform targeted polishing on the threaded surface of the bolt 7 to be processed.

[0029] In this embodiment, a motor controller 19 is fixedly connected to the front side of the workbench plate 1. The output end of the motor controller 19 is electrically connected to the driving motor 11.

[0030] Among them, the motor controller 19 controls the forward and reverse rotation of the driving motor 11, so as to drive the lifting slide 14 and the horizontal conduit 16 to perform reciprocating up and down movement through the driving screw 4. During this process, the polishing slurry ejected from the horizontal conduit 16 performs deburring operations on the surface of the bolt 7 to be processed.

[0031] In this embodiment, a polishing material retaining ring 20 is fixedly connected to the left edge of the top surface of the workbench plate 1. A semi-enclosed transparent retaining ring 21 is detachably connected to the left side of the polishing material retaining ring 20. The bottom end of the polishing material retaining ring 20 is connected to the polishing slurry bucket 17 through a return conduit 22.

[0032] After the polishing slurry ejected from the two horizontal conduits 16 is ejected onto the bolt 7 to be processed, the splashing polishing slurry is blocked by the semi-enclosed transparent retaining ring 22, then flows into the polishing material retaining ring 21, and finally returns to the polishing slurry bucket 17 through the return conduit 22, so as to be pumped back to the horizontal conduit 16 by the two slurry output pumps 18 to process the bolt 7 to be processed;

[0033] After the current bolt 7 to be processed is deburred by grinding, the semi-enclosed transparent retaining ring 21 is removed from above the abrasive retaining ring 20, and then the quick clamp 6 is used to release the fastening and clamping of the current bolt 7 to be processed. The current bolt 7 to be processed is taken out, and then another bolt 7 to be processed is replaced. Finally, the semi-enclosed transparent retaining ring 21 is placed back above the abrasive retaining ring 20, and the above-mentioned deburring work can be carried out on another bolt 7 to be processed.

[0034] In this embodiment, an upper limit switch 23 and a lower limit switch 24 are installed on the front side of the vertical guide rail 13. The upper limit switch 23 is directly above the left side of the lifting slide 14, and the lower limit switch 24 is directly below the left side of the lifting slide 14.

[0035] When the lifting slide 14 moves upward to the upper limit switch 23, the upper limit switch 23 sends an upper limit signal to the motor controller 19. The motor controller 19 makes the drive motor 11 reverse, and the lifting slide 14 moves downward through the drive screw 4. When the lifting slide 14 moves downward to the lower limit switch 24, the lower limit switch 24 sends a lower limit signal to the motor controller 19. The motor controller 19 makes the drive motor 11 rotate forward, and the lifting slide 14 moves upward through the drive screw 4. In this way, the lifting slide 14 drives the two horizontal conduits 16 to perform reciprocating oscillating movement in the up and down directions through the drive screw 4, and the bolt 7 to be processed is deburred during this process.

[0036] In this embodiment, the quick clamp 6 is a pneumatic clamp or a hydraulic chuck, which can quickly clamp and fix and release the clamping of the bolt 7 to be processed, so as to achieve convenient loading and unloading and improve the work efficiency of deburring.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
