Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a machining precision milling mechanism. Background Art

[0002] In mechanical processing, the processing table of parts is usually horizontal, and the top of some parts is inclined. The displacement mechanism of small milling machines is usually linear movement on the horizontal plane and linear movement in the vertical direction. Therefore, when fine milling the top of such parts, the distance between the cutter head and the top surface of the part will change when the milling cutter moves in the horizontal direction. The linear movement in the vertical direction of the small milling machine cannot meet the function of real-time replenishment, and thus cannot meet the processing requirements. In addition, in order to prevent the slide rail from loosening and deviating during use, the horizontal slide rail of the existing small milling machine is usually fixed in the groove, and the iron filings generated during the processing are easily accumulated in the groove, affecting the normal operation of the slide rail.

[0003] Therefore, a machining fine milling mechanism is needed to solve the above technical problems. Utility Model Content

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] like Figure 1 to Figure 6 As shown, a machining fine milling mechanism includes a base 1, the bottom surface of the base 1 is fixed on a processing table, and the bottom of the base 1 is level with the processing table. The top of the base 1 is inclined, and the inclination angle is the same as the inclination angle of the top of the part to be processed, and the top plane of the base 1 is parallel to the top surface of the part to be processed during processing.

[0026] A base 2 is fixed on the top of the base 1. The base 2 includes a bottom plate 21 and two side plates 22. The base 1 and the bottom plate 21 are fixedly connected by bolts. The two side plates 22 are vertically fixed on the upper side of the bottom plate 21, and the two side plates 22 are arranged in parallel. Furthermore, a front plate 23 is vertically fixed on the bottom plate 21, and the two ends of the front plate 23 are fixedly connected to the ends of the two side plates 22, thereby effectively improving the overall structural strength. The tops of the two side plates 22 are provided with step grooves 221, and the two step grooves 221 are opened toward the outside away from each other, and the slide rails 9 are fixed at the step grooves 221. A plurality of slide rail side pressure blocks 17 are fixed by bolts on the side of the two side plates 22 away from each other, and the slide rail side pressure blocks 17 are abutted against the bottom of the side of the slide rail 9. One side of the slide rail 9 abuts against the vertical surface of the step groove 221, and the other side of the slide rail 9 is pressed by the slide rail side pressure block 17, so that the two sides of the slide rail 9 are more stable, and the slide rail 9 is prevented from loosening and deviating due to the side force during operation. The design of the step groove 221 can prevent the debris generated during the machining process from accumulating in the groove. This structure can ensure that the debris has nowhere to accumulate, so that the slide rail can always run smoothly without jamming.

[0027] The slide rail 9 is slidably connected with a slider 10, and the bottom of the slide plate 6 is fixedly connected to the slider 10. The top plane of the slide plate 6 is parallel to the top plane of the base 1. A driving assembly is arranged between the bottom plate 21 and the slide plate 6, and the driving assembly is used to drive the slide plate 6 to move along the slide rail 9. The driving assembly includes a cylinder 13, and a cylinder sleeve 14 is fixed to the movable shaft end of the cylinder 13, and a connecting block 12 is connected to the end of the cylinder sleeve 14, such as Figure 6 As shown, a snap ring is provided at the end of the cylinder sleeve 14, and a slot 16 is provided at the front end of the connecting block 12. The snap ring is inserted into the slot 16 to ensure that the axial connection is fixed. The top surface of the connecting block 12 is fixedly connected to the sliding plate 6. When the cylinder 13 is in motion, it can drive the cylinder sleeve 14, the connecting block 12, and the sliding plate 6 to move along the slide rail 9.

[0028] Furthermore, in order to prevent debris from getting on the slide rail, side shields 7 are fixed on both sides of the sliding plate 6. The side shields 7 are located outside the slide rail 9 and can block debris to prevent it from flying into the side shields. At the same time, they also play a better safety protection role.

[0029] The cylinder mounting plate 11 is fixedly connected between the rear ends of the two side vertical plates 22, and the cylinder 13 is fixedly mounted on the cylinder mounting plate 11. A buffer 15 is fixedly mounted on the cylinder mounting plate 11, and the buffer end of the buffer 15 is directly opposite to the rear end surface of the sliding plate 6. The buffer 15 can prevent the sliding plate 6 from colliding with the cylinder mounting plate 11 when returning to its original position, and plays a good buffering role. A rear shielding cover 8 is fixed to the rear end of the sliding plate 6. The rear shielding cover 8 is located on the upper side of the cylinder 13. The rear shielding cover 8 is "U"-shaped. The rear shielding cover 8 can prevent debris from flying into the space between the sliding plate 6 and the base 2, thereby avoiding affecting the cylinder 13.

[0030] Two sets of fine milling components are vertically fixed on the sliding plate 6. The fine milling components are existing product technologies and can be purchased on the market. The fine milling components include a bracket 3, a motor 4, a spindle 5, etc. The motor 4 is used to drive the spindle 5 to rotate. A milling cutter is installed at the lower end of the spindle 5. The motor 4 and the spindle 5 are both installed on the bracket 3. The direction of the spindle 5 is perpendicular to the top surface of the sliding plate 6.

[0031] When using the machining fine milling mechanism in the utility model to perform fine milling on a part with an inclined top, since the sliding plate 6 and the bottom plate 21 are parallel to the top surface of the part, and the direction of the main shaft 5 is perpendicular to the top surface of the sliding plate 6, the lower end of the milling cutter always maintains the same distance from the top surface of the part during the fine milling process, that is, the feed depth of the fine milling is consistent.
