Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a lifting milling machine with dust removal effect. Background Art

[0002] As a key piece of equipment in the machining field, lift-table milling machines are widely used for milling various metal workpieces. However, during the milling process, a large amount of debris is generated after the workpiece material is cut. This debris not only remains on the ground in the machining area, but also floats in the air due to vibration and airflow during the cutting process, forming dust that is difficult to detect with the naked eye. Currently, mechanical cleaning mechanisms are mainly used to remove debris after machining is completed. However, there is no way to deal with the dust floating in the air, resulting in a decline in workshop air quality and a potential threat to worker health.

[0003] To this end, some lift-table milling machines have tried to use upper exhaust systems or install dust removal protective covers for dust removal. The upper exhaust system not only increases the manufacturing cost of the equipment, but may also limit the operating space of the equipment due to improper pipeline layout; and although the dust removal protective cover can prevent dust from spreading to a certain extent, its closed design seriously limits the workers' operating space; therefore, it is necessary to propose a new dust removal solution for lift-table milling machines. Utility Model Content

[0004] The purpose of the utility model is to overcome the above technical deficiencies, propose a lifting milling machine with dust removal effect, and solve the technical problems raised in the background technology.

[0006] Furthermore, the dust suction mechanism includes a C-shaped dust suction hood, a dust suction groove is provided on the side of the workpiece table, the lower end of the C-shaped dust suction hood is connected to the dust suction groove, an air duct connected to the dust removal chamber is inserted into the dust suction groove, an air inlet is provided on the inner side of the upper part of the C-shaped dust suction hood, and a filter is provided on the air inlet.

[0007] Furthermore, a slag discharge groove is provided inside the C-shaped dust hood, and the slag discharge groove is fixedly connected to the side of the workpiece table. The air inlet is provided above the slag discharge groove, and several sealing rings are provided on one end of the air duct connected to the dust collection groove.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] Reference Figure 1 、 Figure 2 The present invention provides a lifting milling machine with a dust removal effect, comprising a base 1, on which a lifting milling cutter 2 and a workpiece table 3 are provided, and the workpiece table 3 is provided below the lifting milling cutter 2. In order to solve the dust problem generated during the machining process of the existing lifting milling machine, the present invention provides a dust suction mechanism on both sides of the workpiece table 3, and provides a dust removal chamber 102 inside the base 1. A dust separation mechanism 6 is provided in the dust removal chamber 102 for separating the sucked dust from the air; a fan 5 is provided outside the dust removal chamber 102, and its air inlet is connected to the dust removal chamber 102 to provide negative pressure to draw in dust-laden air and perform dust removal treatment; an exhaust hole 101 connected to the air outlet of the fan 5 is provided on the side wall of the base 1 for discharging the air after the dust removal treatment. A detachable dust box 4 is provided on the dust separation mechanism 6 for collecting the separated dust for subsequent cleaning.

[0021] GB / T 19660-2005 "Machine Tool Coordinate System" (equivalent to the ISO standard) states: In a vertical milling machine, "the Z axis is the tool spindle direction, and the X / Y axis is the worktable plane movement direction." The tool vertical travel (Z direction) and the worktable horizontal plane (X / Y plane) together constitute the machining space. The "UG NX CNC Machining Tutorial" states: The vertical CNC milling machine coordinate system states that "the tool motion range is defined by the workpiece table plane (XY plane) and the spindle travel (Z axis)." There is no tool motion trajectory outside the worktable.

[0022] Reference Figure 3 、 Figure 4The dust separation mechanism 6 includes a bottom plate 601, the outer edge of which is fixedly connected to the inner wall of the dust removal chamber 102. A separation bracket 602 is provided on the bottom plate 601, and a plurality of separation plates 7 are inclinedly provided on the separation bracket 602. The dust collecting box 4 is provided below the separation plate 7 for collecting the separated dust. The separation plate 7 includes a horizontal support plate 702 and a vertical support plate 701. A plurality of angle steels 703 are provided between the horizontal support plate 702 and the vertical support plate 701. Two adjacent angle steels 703 are interlocked and their adjacent edges are parallel. When the dust-containing air is sucked through the separation plate 7, it flows through the gap between the adjacent edges of the two angle steels 703. The tortuous path reduces the air flow rate, so that the dust carried in the air settles under the action of gravity and slides along the grooves of the angle steels 703. The horizontal support plate 702 is provided with a plurality of dust discharge holes 704, so that the settled dust falls into the dust collecting box 4.

[0023] In the first chapter of the Basic Theory of Separation Technology in Dust Removal and Separation Technology (Chen Hongfei, 2007), inertial dust removal is defined as the dust removal method in which "the direction of movement of the dust-laden gas suddenly changes when it encounters the baffle, and the dust particles, due to their larger mass, maintain their original trajectory and hit the baffle to separate."

[0024] Reference Figure 5 , Figure 6 The dust collection mechanism includes a C-shaped dust collection hood 303, and a slag discharge trough 302 is also provided inside the C-shaped dust collection hood 303. The slag discharge trough 302 is fixedly connected to the side of the workpiece table 3. An air inlet 306 is provided on the inner side of the upper part of the C-shaped dust collection hood 303, and the slag discharge trough 302 is provided below the air inlet 306. Metal debris generated during milling machine processing falls into the slag discharge trough 302 under the action of gravity. Since the air inlet 306 is provided above the slag discharge trough 302, the entry of metal debris is effectively avoided, and a filter is provided on the air inlet 306 to further prevent large particles of impurities from entering the dust collection mechanism.

[0025] A dust suction groove 301 is provided on the side of the workpiece table 3, and the lower end of the C-shaped dust suction cover 303 is connected to the dust suction groove 301. An air duct 304 connected to the dust removal chamber 102 is inserted into the dust suction groove 301 for introducing the sucked dust into the dust removal chamber 102. Several sealing rings 305 are provided on one end of the air duct 304 connected to the dust suction groove 301 to ensure the sealing of the connection and the dust suction effect.

[0026] In order to further optimize the dust removal effect, there are two separation brackets 602. The two separation brackets 602 are mirror-imaged with the center line of the base plate 601 as the center. The air inlet of the fan 5 is set between the two separation brackets 602. The ends of the two air ducts 304 on both sides of the workpiece table 3 are respectively set above the two separation plates 7. The efficiency of air purification is improved by the two groups of separation plates 7.

[0027] In order to facilitate the understanding of the present invention, the following Figure 1 - Figure 6 The working principle of this solution is explained in detail: when the lifting milling machine is processing, the fan 5 is started to form a negative pressure in the dust removal chamber 102, and the dust generated on the workpiece table 3 will be sucked into the C-shaped dust hood 303 and introduced into the dust removal chamber 102 through the air duct 304. In the dust removal chamber 102, the dust will be separated from the air under the action of the airflow and the separation plate 7, and fall into the dust box 4. The air after dust removal will be drawn out through the air inlet of the fan 5 and discharged to the outside of the base 1 through the exhaust hole 101. The utility model can not only effectively collect the dust generated during the cutting process, but also avoid restricting the operation of the equipment and the operating space of the workers, thereby improving the air quality in the workshop.

[0028] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
