Description

Technical Field

[0001] The utility model relates to the technical field of chamfering equipment, in particular to a sleeve chamfering machine. Background Art

[0002] During the processing of aluminum-plastic film rolls, after the rolls are cut into equal parts, many burrs will be distributed on the inner edge of the rolls due to the influence of the plastic material of the rolls. Once the burrs extend out, they are easy to puncture the plastic film rolls in storage or transportation, so the inner edge of the rolls needs to be polished.

[0003] In the prior art, due to the large length of the sleeve, it is difficult for the commonly used chamfering machine to grind the inner edge of the sleeve. Therefore, after the sleeve is fixed, the inner edge of the drum is usually grinded manually using a chamfering drill bit, and a hand grinder is used to drive the high-speed rotation of the chamfering drill bit. However, manual chamfering will inevitably have an adverse effect on processing efficiency. Utility Model Content

[0034] The utility model is further described below in conjunction with embodiments.

[0035] Example:

[0036] See attached Figure 1-5 As shown, the present solution proposes a sleeve chamfering device, comprising a frame 1, the upper end of which is a plane, and a sleeve fixing mechanism 2 and a chamfering mechanism 3 are sequentially arranged.

[0037] The sleeve fixing mechanism 2 is used to fix the sleeve to be chamfered. The sleeve fixing mechanism 2 includes a first fixing platform 21 and a second fixing platform 22 which are symmetrically distributed up and down, and a concave surface is opened at the opposite ends of the two fixing platforms. The second fixing platform 22 is arranged on the frame 1 and the distance between the two fixing platforms is adjustable.

[0038] Specifically, the concave surfaces on the two fixed platforms are semicircular, and a door-shaped vertical plate is arranged above the second fixed platform 22. A driving member for driving the first fixed platform 21 to move back and forth is arranged above the vertical plate. The driving member can be a telescopic push rod and the output end is fixed on the first fixed platform 21. A commonly used linear driving mechanism such as a screw rod can also be used. No limitation is made here. In this case, a telescopic push rod is used as the driving member.

[0039] The sleeve fixing mechanism 2 also includes a bracket 23 arranged on the side of the second fixed table 22 away from the chamfering mechanism 3. The upper end surface of the bracket 23 is an arc surface and is used to support the sleeve. The bracket 23 extends along one side of the frame 1 and has an arc-shaped cross-section. The upper end arc surface of the bracket 23 is coaxial with the upper end concave surface of the second fixed table 22. When in use, the sleeve to be processed is placed on the bracket 23, and the sleeve is pushed and extended between the two fixed tables. After being pushed to the fixed position, the first fixed table 21 is moved down and pressed on the upper end surface of the sleeve to form a longitudinal fixation.

[0040] The sleeve fixing mechanism 2 further comprises a limiting plate 24 which is perpendicular to the sleeve. The limiting plate 24 is movably mounted on a side of the sleeve fixing mechanism 2 which faces the chamfering mechanism 3 , and the distance between the limiting plate 24 and the sleeve is adjustable.

[0041] Specifically, a telescopic push rod is connected to the rear side of the limit plate 24, which is used to push the limit plate 24 to move linearly in the vertical direction of the sleeve. How to judge whether the sleeve moves to the specified position on the bracket 23 is based on the position of the limit plate 24. When the sleeve is placed on the bracket 23 and pushed between the two fixed platforms, the limit plate 24 is placed on the moving path of the sleeve to "intercept" the sleeve. In this case, the limit plate 24 is parallel to the end face of the first fixed platform 21 and / or the second fixed platform 22, and is arranged at the junction of the two fixed platforms.

[0042] The chamfering mechanism 3 includes a chamfering cutter head 31, which can rotate and chamfer the inner edge of the sleeve on the sleeve fixing mechanism 2; wherein the chamfering cutter head 31 and the sleeve on the sleeve fixing mechanism 2 are equiaxially arranged and the distance between the chamfering cutter head 31 and the sleeve is adjustable.

[0043] The selection of the chamfering cutter head 31 is not specifically limited. In this case, the chamfering cutter head 31 is generally conical in shape, and has three cutting grooves distributed circumferentially on its outer end surface. Each cutting groove bends and extends from the outer end of the chamfering cutter head 31 toward the center of the chamfering cutter head 31.

[0044] The chamfering mechanism 3 includes a box body 32, which is arranged on the side of the two fixed platforms away from the sleeve. The chamfering head 31 and the driving mechanism 33 for driving the chamfering head 31 to rotate are arranged in the box body 32. When the sleeve enters the processing position, the driving mechanism 33 will move toward one side of the sleeve and allow the chamfering head 31 to contact the inner edge of the sleeve. At this time, the driving mechanism 33 starts to work and drives the chamfering head 31 to rotate at high speed to grind and chamfer the inner edge of the sleeve. After processing, the driving mechanism 33 is reset, and the chamfering head 31 exits the processing position.

[0045] In the present case, the driving mechanism 33 is movably connected to the frame 1 through a guide rail. The bottom end of the driving mechanism 33 is provided with a guide rail, and the upper end of the frame 1 is provided with a track matching the guide rail. An electric push rod 331 is provided on one side of the driving mechanism 33, and the electric push rod 331 is used to drive the driving mechanism 33 to move toward one side of the sleeve.

[0046] In order to facilitate observation of the current chamfering situation, in the present case, an observation cover 321 is hinged on the box body 32 and located above the chamfering head 31. Specifically, the observation cover 321 is arranged on the upper end of one side of the box body 32 facing the two fixed platforms, and the observation cover 321 is made of transparent material, which is more convenient for observation. The observation cover 321 can effectively isolate the debris generated during chamfering to avoid splashing and causing harm to operators near the frame 1.

[0047] In order to facilitate movement, a support leg 11 is respectively arranged around the bottom end of the frame 1 in this case, and a universal wheel 111 is arranged at the bottom end of each support leg 11.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
