Description

Technical Field

[0001] The utility model belongs to the technical field of instrument processing equipment, and in particular relates to automatic edge trimming and burr removal equipment for an instrument shell. Background Art

[0002] In the instrument manufacturing process, the production of cylindrical housing components involves fixing the raw materials in the machining center for fine shaping. Considering the small size and thin wall characteristics of the instrument housing, the machining process requires precise carving of the embedding grooves for accommodating the instrument components, as well as the docking tube structure to ensure the stable assembly of the instrument lens. However, this precision machining process will inevitably produce tiny excess metal protrusions, i.e. burrs, on the edge of the housing. The presence of these burrs will not only hinder the precise embedding of the subsequent internal components of the instrument and the smooth installation of the transparent lens, but also have an adverse effect on the user's final experience, reducing the overall texture and operational satisfaction of the product. Eliminating burrs has become one of the key steps to ensure the quality of instrument housing machining.

[0003] Therefore, it is necessary to study an automatic cutting and deburring device for instrument housing that can automatically cut and remove burrs from the instrument housing. Utility Model Content

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] See also Figures 1 to 3 As shown, an automatic trimming and deburring device for an instrument housing comprises: a frame 1 for supporting and guiding the instrument housing, a cutting mechanism 2 for cutting burrs on the instrument housing, and a driving mechanism for driving the cutting mechanism 2 to work.

[0025] The frame 1 is provided with a gear frame 12 and a cutting hole 13. Specifically, a positioning plate 11 is fixedly provided on the frame 1, and it can be understood that the blank is rolled to the cutting station through the positioning plate 11.

[0026] The cutting mechanism 2 includes a telescopic rod 21, a first connecting rod 22, a second connecting rod 23, a rotating shaft 24 and a cutting head 25. A bracket 211 is fixedly provided on the telescopic rod 21, one end of the first connecting rod 22 is hinged on the telescopic rod 21, and the other end is hinged to one end of the second connecting rod 23, the second connecting rod 23 is hinged on the bracket 211, and the end of the second connecting rod 23 away from the hinge is matched with the rotating shaft 24. It can be understood that when the telescopic rod 21 is extended, the first connecting rod 22, the second connecting rod 23 and the bracket 211 are matched, thereby driving the end of the second connecting rod 23 matched with the rotating shaft 24 to swing toward the side of the cutting head 25; when the telescopic rod 21 is shortened, the first connecting rod 22, the second connecting rod 23 and the bracket 211 are matched, thereby driving the end of the second connecting rod 23 matched with the rotating shaft 24 to swing away from the cutting head 25. The rotating shaft 24 is slidably disposed on the gear frame 12 . The rotating shaft 24 is fixedly connected to the cutting head 25 . The cutting head 25 is matched with the cutting hole 13 .

[0027] The driving mechanism includes a first pulley 31, a second pulley 32, a belt 33, a rotating shaft 34 and a motor 35.

Specifically, a spline 243 is provided on the rotating shaft 24, and a keyway that cooperates with the spline 243 is provided on the inner wall of the second pulley 32. The rotating shaft 24 and the first pulley 31 are slidably matched. It can be understood that the spline 243 on the rotating shaft 24 is slidably matched with the keyway provided on the inner wall of the first pulley 31. The rotation of the first pulley 31 can drive the rotating shaft 24 and the cutting head 25 to rotate, and the two can also slide relative to each other. The second pulley 32 is fixedly provided on the rotating shaft 34, the first pulley 31 is connected to the second pulley 32 via a belt 33, the motor 35 is fixedly mounted on the frame 1, and the motor 35 cooperates with the rotating shaft 34.

It can be understood that when the second connecting rod 23 is turned over toward the cutting head 25, the shift fork 231 is matched with the first positioning ring 241, thereby driving the rotating shaft 24 to slide toward the cutting hole 13 while being selected, so that the cutting head 25 is in contact with the instrument housing to cut the burrs on the instrument housing; when the second connecting rod 23 is turned over toward the cutting head 25, the shift fork 231 is matched with the second positioning ring 242, driving the rotating shaft 24 to slide in a direction away from the cutting hole 13 while rotating, so that the cutting head 25 is no longer in contact with the instrument housing.
