Description

Technical Field

[0001] The utility model relates to the technical field of parts processing, in particular to a scraper for shaft end surfaces. Background Art

[0002] During the machining process, shaft workpieces are prone to produce a large number of burrs on the end face of the shaft due to the influence of the tool speed and the sharpness of the tool head, and these burrs will affect the quality of the shaft workpiece. At present, the burrs are often scraped off by a scraper after the machining is completed. During the scraping, the outer wall of the shaft is an arc surface, so the scraper is tightly pressed against the outer circumference of the shaft, and it is easy to cause the scraper and the shaft to lose contact when pressure is applied, which will cause scratches to the operator, and the scraping efficiency is also low. Utility Model Content

[0003] The utility model provides a scraper for shaft end faces to solve the deficiencies of the prior art, facilitate the scraping operation of burrs on shaft end faces and chamfers, improve the scraping efficiency and safety during operation, and has strong practicality.

The screw rod can be rotated so that the clamping plate is pressed tightly against the outer wall of the shaft, and the ring is positioned by the clamping plate. Of course, it is necessary to ensure that the ring and the shaft are coaxial during clamping.

When performing a scraping operation, the scraper can be rotated to act on the outer wall of the shaft, and the outer wall and end face of the shaft can be scraped by the scraper. In order to expand the adaptability, an adjusting screw is provided, by rotating the adjusting screw the blade of the scraper can be pressed against the outer periphery of the shaft. When scraping, the burrs on the shaft and its end surface can be cleaned by simply rotating the scraper.

[0007] The movable block is provided with a convex seat, the upper end of which is rotatably provided with a transverse screw rod, the outer end of which is provided with a rotating head, a screw seat is provided on the transverse screw rod, a concave piece is provided at the lower end of the screw seat, a blade is provided at the lower end of the concave piece, and the blade is provided to facilitate the scraping of burrs on the conical surface of the shaft end face. The transverse screw rod is provided to improve adaptability.

[0008] Furthermore, in order to improve the clamping effect of the clamping plate, the inner wall of the clamping plate is a concave arc structure.

[0009] Furthermore, in order to remove burrs from the junction between the shaft end face and its outer peripheral wall, a triangular structure is formed at the other end of the scraper.

[0010] Furthermore, in order to facilitate deburring of the end surface of the shaft, the other end and the lower wall of the scraper are provided as a blade.

[0011] Furthermore, in order to ensure the stability of the concave member, a transverse waist-shaped hole is opened on the scraper, and a movable guide rod is passed through the concave member, and the movable guide rod passes through the transverse waist-shaped hole.

[0012] Furthermore, this method facilitates burr removal on the conical surface of the shaft end face, and the inner end of the blade is a bevel, and a blade is formed on the bevel.

[0020] like Figure 1~Figure 4As shown, a scraper for the end surface of a shaft includes a plurality of L-shaped seats 1 arranged in a circular array, a screw rod 10 is screwed on the vertical section of the L-shaped seat 1, a clamping plate 11 is rotatably provided at the inner end of the screw rod 10, the inner wall of the clamping plate 11 is a concave arc structure, and a rotatable end cap 12 is provided at the outer end of the screw rod 10.

[0021] A ring 2 is mounted on the L-shaped seat 1. The upper end of the ring 2 is formed with a T-shaped ring groove 20. An inner plate 21 is arranged in the T-shaped ring groove 20. A connecting screw is arranged on the inner plate 21. A connecting plate 22 is arranged on the upper end of the connecting screw. A vertical plate 3 is arranged on the inner side end of the connecting plate 22. An L-shaped plate 30 is arranged on the upper end of the vertical plate 3. A pair of moving holes 31 are opened on the horizontal section of the L-shaped plate 30. A pair of guide screws 34 are inserted in the moving holes 31. A moving seat 33 is mounted on the lower end of the guide screw 34. An adjusting screw 32 is screwed on the moving seat 33. The outer end of the adjusting screw 32 is rotatably arranged on the outer end of the L-shaped plate 30. A rotating cap 36 is arranged on the outer end of the adjusting screw 32. A movable block 35 is mounted on the upper end of the guide screw 34. A scraper 37 is arranged on the movable block 35. The other end of the scraper 37 is in a triangular structure, and the other end and the lower wall of the scraper 37 are blades. A convex seat 4 is installed on the movable block 35, and a transverse screw rod 40 is rotatably provided on the upper end of the convex seat 4, and a rotating head 41 is provided on the outer end of the transverse screw rod 40. A screw seat 42 is provided on the transverse screw rod 40, and a concave piece 43 is installed on the lower end of the screw seat 42. A transverse waist-shaped hole 38 is opened on the scraper 37, and a movable guide rod 44 is passed through the concave piece 43. The movable guide rod 44 passes through the transverse waist-shaped hole 38, and a blade 45 is installed at the lower end of the concave piece 43. The inner end of the blade 45 is an inclined surface, and a blade is formed on the inclined surface.

[0022] When operating this embodiment, the operator first sleeves the ring 2 onto one end of the shaft.

[0023] Then the operator adjusts the position of the clamping plate 11 through the screw 10, and finally makes the clamping plate 11 act on the outer wall of the shaft, and finally fixes the ring 2 on the shaft. When clamping, it is also necessary to ensure that the shaft and the ring are coaxial.

[0024] Then the operator drives the movable block 35 to move inward along the length direction of the movable hole 31 by adjusting the screw rod 32 until the inner end of the scraper 37 acts on the outer periphery of the shaft or the junction of the outer periphery of the shaft and the end face, and the inner wall blade of the scraper 37 also needs to act on the end.

[0025] Then the operator rotates the scraper 37, and through the rotation, the blade portion of the scraper 37 completes the burr cleaning operation on the end surface and the outer periphery of the shaft.

[0026] If there is a conical chamfer on the end face of the shaft, the operator adjusts the position of the blade 45 through the transverse screw 40 so that the cutting edge of the inclined surface of the blade 45 can scrape off the burrs on the conical chamfer.
