The drilling device for roller processing can realize rapid positioning of the shaft parts by directly contacting and fixing the two ends of the shaft parts, and rotating the shaft parts according to the need of the drilling angle, thereby improving the production efficiency of the shaft parts.

[0004] The drilling device can discharge debris by providing a debris discharge chamber. However, when the roller is disassembled and assembled from the top plate, there is a risk of the roller falling downward because the lower side of the roller has no support. The roller hits the debris discharge chamber, which can easily cause damage to the device and the workpiece.

[0005] Therefore, in order to solve the above-mentioned problem, a drilling device for roller shaft machining is proposed. Utility Model Content

Their principles and connection methods are existing technologies well known to technicians in this field, so they will not be repeated here.

[0025] A drilling device for roller processing, comprising: a box body 1, a guide groove 11 is provided on the inner bottom surface of the box body 1, a slide groove 12 is provided on the top surface of the box body 1, and a fixing mechanism 13 is installed on the inner wall of the box body 1;

[0026] A support structure 2 is installed on the inner side of the box body 1. The support structure 2 includes a support plate 21. The support plate 21 is movably installed on the inner side of the box body 1. A through hole 22 is provided on the top surface of the support plate 21. Guide pillars 23 are fixedly connected to the front and rear surfaces of the support plate 21. The end fixing plates of the guide pillars 23 are connected to springs 24. Rubber sheets 25 are fixedly connected to the front and rear ends of the top surface of the support plate 21. A connecting rod 26 is fixedly connected to the back of the support plate 21. A motor 27 is fixedly installed on the back of the box body 1. A cam 28 is fixedly connected to the output end of the motor 27. The support plate 21 can support the roller shaft at the lower side to facilitate the disassembly and assembly of the roller shaft on the fixing mechanism 13. At the same time, the through hole 22 is provided to facilitate the debris to fall downward into the guide groove 11 for easy discharge. The support plate 21 can swing back and forth to reduce the accumulation of debris on the top surface of the support plate 21.

[0027] A drilling structure 3 is installed on the top surface of the box body 1, and the drilling structure 3 includes a threaded rod 31. The threaded rod 31 is movably installed on the inner side of the slide groove 12 through a bearing. A threaded block 32 is threadedly connected to the outer middle part of the threaded rod 31. A motor 33 is installed on the bottom surface of the threaded block 32. A drill 34 is fixedly installed on the right side wall of the box body 1. The roller shaft can be drilled by starting the motor 33. The drill 34 is started and drives the threaded rod 31 to rotate. The threaded rod 31 is threadedly connected to the threaded block 32. The rotation of the threaded rod 31 drives the threaded block 32 to move in the slide groove 12. The left and right positions of the motor 33 can be adjusted to facilitate the adjustment of the drilling position of the roller shaft.

[0028] Furthermore, the front end of the guide groove 11 passes through the front side of the box body 1 , and the debris in the box body 1 can be discharged through the guide groove 11 .

[0029] Furthermore, the top surface of the support plate 21 is lower than the bottom surface of the inner side of the box body 1 , and the guide pillars 23 are inserted on the inner wall of the box body 1 , and the guide pillars 23 provide guide limits for the movement of the support plate 21 inside the box body 1 .

[0030] Furthermore, one end of the spring 24 is fixedly connected to the inner wall of the box body 1, and one end of the rubber sheet 25 is fixedly connected to the inner wall of the box body 1. The spring 24 provides power for the support plate 21 to reset inside the box body 1 when the cam 28 is separated from the connecting rod 26. The rubber sheet 25 blocks the upper side of the gap between the support plate 21 and the inner wall of the box body 1, which can prevent debris from moving to the edge of the support plate 21 and avoid debris from being stuck between the support plate 21 and the box body 1, thereby affecting the smoothness of the movement of the support plate 21 and improving the practicality of the device.

[0031] Furthermore, the connecting rod 26 is in an "L" shape, and the connecting rod 26 passes through the rear wall of the box body 1. The cam 28 cooperates with the connecting rod 26. When the protruding end of the cam 28 contacts the connecting rod 26, it can drive the connecting rod 26 and the support plate 21 to move, so that the support plate 21 can swing back and forth in the box body 1, and the debris accumulated on the top surface of the support plate 21 can be shaken into the through hole 22, so that the debris can be completely discharged through the guide groove 11 to ensure the user experience.

[0032] Furthermore, the output end of the drill 34 is fixedly connected to the threaded rod 31, and the threaded rod 31 is threadedly connected to the threaded block 32. The drill 34 provides power for the rotation of the threaded rod 31, and the rotation of the threaded rod 31 can drive the movement of the threaded block 32, thereby adjusting the position of the motor 33 on the inner side of the box body 1.

[0033] Working principle: During processing, the roller shaft is placed on the top surface of the support plate 21, and the support plate 21 can support the roller shaft at the bottom. The fixing mechanism 13 is started to clamp and fix the roller shaft on both sides. The motor 33 is started to perform drilling processing on the roller shaft. The drill 34 is started, and the drill 34 drives the threaded rod 31 to rotate. The threaded rod 31 is threadedly connected with the threaded block 32. The rotation of the threaded rod 31 drives the threaded block 32 to move in the slide groove 12. The left and right positions of the motor 33 can be adjusted to facilitate the adjustment of the drilling position of the roller shaft.

[0034] After the processing is completed, the motor 27 is started, and the motor 27 drives the cam 28 to rotate. When the cam 28 rotates, the convex end contacts the connecting rod 26, and the supporting plate 21 can be driven to move through the connecting rod 26. The supporting plate 21 moves inside the box body 1 through the guide column 23. When the supporting plate 21 moves, the spring 24 is deformed. When the convex end of the connecting rod 26 is separated from the connecting rod 26, the supporting plate 21 is reset under the action of the spring 24, so that the supporting plate 21 shakes back and forth in the box body 1, and the debris accumulated on the top surface of the supporting plate 21 can be shaken into the through hole 22, so that the debris can be completely discharged through the guide groove 11 to ensure the user experience;

[0035] When the support plate 21 moves, the rubber sheet 25 can be deformed. The rubber sheet 25 can be blocked on the upper side of the gap between the support plate 21 and the inner wall of the box body 1, which can prevent debris from moving to the edge of the support plate 21 and prevent debris from being stuck between the support plate 21 and the box body 1, thereby affecting the smoothness of the movement of the support plate 21 and improving the practicality of the device.

[0036] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
