Description

Technical Field

[0001] The invention relates to the technical field of parts processing, in particular to a drilling and milling machine tool for processing precision metal parts. Background Art

[0002] There are many methods for processing mechanical parts in modern machinery manufacturing: in addition to cutting, there are casting, forging, welding, stamping, extrusion, etc. However, all parts with high precision requirements and fine surface roughness requirements generally need to be processed by cutting on machine tools.

[0003] Generally, when drilling a workpiece, the drill bit is basically controlled to rotate downward and drill after setting parameters. When the position of the drill bit is difficult to adjust during the drilling process, when drilling deeper in the workpiece, due to the continuous contact and cutting action between the drill bit and the hole wall, the shear force in the hole wall exerted on the drill bit will gradually increase with the depth. Subsequently, when the drill bit continues to drill downward in the deep hole, since it is difficult to adjust the position of the drill bit, the drill bit may easily break or be damaged under the action of the large shear force, thereby affecting the subsequent processing efficiency.

[0038] The present invention has the following beneficial effects:

[0039] 1. The present invention can gradually open the horn as the drill shaft moves downward, and can push the two arc plates to rotate in opposite directions through the cooperation of the trapezoidal block and the trapezoidal block 2 through the two T-shaped plates. When the two arc plates rotate in opposite directions, they will drive the workpiece to move downward through the square plate, and then when the trapezoidal block 2 is separated from the trapezoidal block, the return spring at the bottom of the square plate will push the workpiece to move up and reset. Driving the workpiece to move downward and reset during processing through the square plate can reduce the situation where the drill bit is broken or damaged due to the continuous contact between the drill bit on the drill shaft and the deeper hole wall and the excessive shear force on the side wall of the deeper hole when the drill shaft drills to a deeper depth. The opening of the horn and the cooperation of the square plate drive the workpiece to move up and down, and then the continuous shearing process can be interrupted, thereby dispersing the shear stress and reducing the occurrence of broken edges, thereby improving the subsequent processing efficiency.

[0040] 2. The present invention drives the C-shaped frame to slide upward by the arc plate, so that the hollow arc plate can slide in a circle. At this time, the hollow arc plate will form a semicircular hook shape. When the hollow arc plate rotates, the circular hook shape can push the movable frame to slide upward through its side wall and squeeze the side wall of the workpiece at the same time, so that the H frame can make close contact with the side wall of the workpiece, which can reduce the situation that when the workpiece slides downward, the hole of the workpiece moves downward under the shear force of the drill shaft when drilling the hole because the workpiece is no longer subjected to the downward pressure of the drill shaft when drilling, resulting in the deviation and sliding of the workpiece as the drill shaft rotates when the workpiece moves downward, and reduce the deviation of the borehole diameter caused by the axial misalignment between the drill hole and the drill shaft when the workpiece is subsequently moved upward and reset, thereby improving the subsequent processing accuracy and processing quality.

[0041] 3. According to the present invention, when the hollow arc plate forms a semicircular hooking movement, the spring block is squeezed and the cross plate is pushed to slide upward. The roller ring slides in the direction of the workpiece under the push of the arc surface when the cross plate slides and rotates downward when sliding. The downward rotation of the roller ring can make the cross plate slide downward on the surface of the workpiece. After that, the roller ring shrinks and deforms when the cross plate continues to move upward and forms an ellipse under the top side wall of the workpiece and generates a lateral downward pressure on the workpiece, thereby reducing the situation that the workpiece tilts when the drill shaft is processing the periphery of the center of the workpiece due to excessive lateral force on the workpiece when it is clamped and moved downward by the C-shaped frame. At the same time, the lateral downward pressure on the workpiece by the rotation of the roller ring and the ellipse formed can also reduce the excessive friction between the workpiece and the multiple H frames when the multiple H frames are tightly clamped on the workpiece, which makes it difficult for the workpiece to move downward with the square plate, and the gap between the square plates causes the workpiece to tilt when the square plate is subsequently reset, thereby enhancing the accuracy of the workpiece position when the workpiece slides down and resets, and enhancing the stability and accuracy of subsequent processing.

[0079] The flip assembly 22 includes two arc-shaped plates 221 rotatably connected to the top of the sliding plate 211.

The sliding of the C-shaped frame 231 driven by the arc plate 221 can make the hollow arc plate 243 slide upward and in a circle. At this time, the hollow arc plate 243 will form a semicircular hook shape. When the hollow arc plate 243 rotates, the circular hook shape formed can push the movable frame 321 to slide upward through its side wall, and at the same time, the side wall of the workpiece is pressed against it.

[0082] The tilting member includes a tilting plate 312 fixedly connected to the top of the spring block 311, and a sliding rod 313 is fixedly connected to the front and back of the tilting plate 312;

[0084] One end of the spring block 311 close to the square plate 213 is fixedly connected to the side wall of the rectangular groove 212 .

[0085] The movable assembly 32 includes a movable frame 321 fixedly connected to the top of the two tension springs, a square groove 322 is formed on one side of the movable frame 321 close to the square plate 213, and a cross groove 323 is formed on the side wall of the movable frame 321;

[0086] The flipping member includes a flipping plate 331 rotatably connected to the side of the movable frame 321 away from the square plate 213, the end of the flipping plate 331 away from the movable frame 321 is rotatably connected to the movable plate, the end of the movable plate away from the flipping plate 331 is rotatably connected to the cross plate 332, the cross plate 332 is slidably connected to the inside of the cross groove 323, when the roller ring 333 is squeezed by the arc surface of the cross plate 332, it will slide in the direction of the workpiece and produce a downward rotation under the squeezing of the arc surface of the cross plate 332 during sliding, and the downward rotation of the roller ring 333 can make it slide downward on the surface of the workpiece.

[0087] The movable assembly 32 includes a short rod fixedly connected to the inside of the cross groove 323, and the outer surface of the short rod is rotatably connected to a roller ring 333, and the outer surface of the roller ring 333 contacts the side wall of the square groove 322;

[0088] The fitting component 34 includes an auxiliary spring 2 fixedly connected to the inner wall of the square groove 322 away from the square plate 213. The side wall of the auxiliary spring 2 is fixedly connected to an H frame 341. The side wall of the H frame 341 is rotatably connected to two ball bearings 2. When the hollow arc plate 243 forms a semicircular hooking movement, the spring block 311 is squeezed and the cross plate 332 is pushed to slide upward. The roller ring 333 will slide in the direction of the workpiece under the push of the arc surface when the cross plate 332 slides and produce a downward rotation when sliding.

[0089] When in use, first place the workpiece to be processed on the top of the square plate 213 so that it is between multiple H frames 341, and then adjust the position of the sliding plate 211 on the limit plate 121 by rotating the adjusting threaded rod, and then connect the two water pipes 112 to the external water source. After setting the parameters on the control panel 101, the control panel 101 will control the electrical box 111 to slide back and forth and control the corresponding electric column 113 to move downward to complete the drilling and milling work.

[0090] When the electric column 113 drives the drill shaft 115 to move downward to drill a workpiece, the downward movement of the electric column 113 will drive the horn 114 to move downward synchronously. When the horn 114 moves downward, its bottom will contact the surface of the workpiece. When the horn 114 contacts the surface of the workpiece as the drill shaft 115 moves downward, the horn 114 will gradually form an expansion movement to the surroundings as the drilling depth of the drill shaft 115 increases. When the drill shaft 115 reaches a certain depth and stops moving downward, the trapezoidal blocks on the side walls of the horn 114 will contact the trapezoidal blocks 2 on the side walls of the two T-shaped plates 223 after being fully opened. Then, when the drill shaft 115 drives the horn 114 to rotate, the rotation of the horn 114 will push the T-shaped plates 223 to slide outward through the trapezoidal blocks. When the two T-shaped plates 223 slide, they will push the arc plates 221 so that the two arc plates 221 move forward. The two arc plates 221 rotate in opposite directions. When the two arc plates 221 rotate in opposite directions, the square plate 213 is driven to slide downward through the T-shaped shaft 222. When the square plate 213 slides downward, the workpiece is driven to slide downward on the surface of the drill shaft 115. After that, when the trapezoidal block on the T-shaped plate 223 is separated from the horn 114, the square plate 213 is driven to reset the workpiece upward. The square plate 213 drives the workpiece to move downward and reset during drilling, which can reduce the chipping or damage of the drill bit due to the continuous contact between the drill bit on the drill shaft 115 and the deeper hole wall and the excessive shear force on the side wall of the deeper hole during cutting when the drill shaft 115 is drilled to a deeper depth. The square plate 213 drives the workpiece to move up and down, and then the continuous shearing process can be interrupted, thereby dispersing the shear stress and reducing the occurrence of chipping, thereby improving the subsequent processing efficiency.

[0091] When the two arc plates 221 rotate in opposite directions, the rotation of the arc plates 221 will drive the C-shaped frame 231 to slide. When the C-shaped frame 231 slides, it will drive the hollow arc plate 243 to slide through the reinforcing plate 241 and the long rod 242. When the hollow arc plate 243 slides, the hollow arc plate 243 will be restricted by the short axis and will produce an upward circular sliding when sliding. When the hollow arc plate 243 slides upward in a semicircle, the moving hollow arc plate 243 will rotate in a semicircle, and the side wall of the hollow arc plate 243 will generate a hooking driving force on the side wall of the movable frame 321. When the semicircular movement of the hollow arc plate 243 pushes the movable frame 321, it will drive the movable frame 321 on the surface of the sliding rod 313. While the surface slides upward, it will also drive the movable frame 321 to squeeze and fit the side wall of the workpiece. When the movable frame 321 squeezes the side wall of the workpiece, it will drive the H frame 341 to come into close contact with the side wall of the workpiece. The squeezing and fitting of the movable frame 321 and the H frame 341 on the side wall of the workpiece can reduce the situation when the workpiece slides downward. Because the workpiece is no longer subjected to the downward pressure of the drill shaft 115 when drilling, the hole of the workpiece is offset and slipped as the drill shaft 115 rotates when the workpiece moves downward under the shear force of the drill shaft 115 when drilling. This reduces the deviation of the borehole diameter caused by the misalignment of the axis between the drill hole and the drill shaft 115 when the workpiece is subsequently moved upward and reset, thereby improving the subsequent machining accuracy and machining quality.

[0092] When the hollow arc plate 243 is pushed by the long rod 242 to make a semicircular hooking movement, the movement of the hollow arc plate 243 will squeeze the side wall of the flip plate 331 through its edge. After the side wall of the flip plate 331 is squeezed, it will push the cross plate 332 to slide upward through the reinforcing plate. When the cross plate 332 slides upward, the arc surface on the cross plate 332 will squeeze the side wall of the roller ring 333. When the roller ring 333 is squeezed by the arc surface of the cross plate 332, it will slide in the direction of the workpiece and produce a downward rotation under the squeezing of the arc surface of the cross plate 332 during sliding. The downward rotation of the roller ring 333 can make it slide downward on the surface of the workpiece. Subsequently, when the roller ring 333 is squeezed and slides in the direction of the workpiece, the roller ring 333 will shrink and deform under the continuous upward movement of the cross plate 332. When the roller ring 333 shrinks and deforms, it will The ellipse is formed at the wall and a lateral downward pressure is generated on the top side wall of the workpiece. Combined with the downward rotation of the roller ring 333 on the side wall of the workpiece, the workpiece can be moved downward smoothly as the square plate 213 moves downward, thereby reducing the situation where the drill shaft 115 is subjected to excessive lateral force when processing the side wall of the workpiece, and the workpiece is tilted when it is clamped by the C-shaped frame 231 and moves downward. At the same time, the lateral downward pressure on the workpiece by the rotation of the roller ring 333 and the ellipse formed can also reduce the excessive friction between the workpiece and the multiple H frames 341 when the multiple H frames 341 tightly clamp the workpiece, resulting in a gap and the workpiece being unable to move downward with the square plate 213, causing the square plate 213 to tilt when the workpiece is subsequently reset. This can enhance the accuracy of the workpiece position when the workpiece slides down and is reset, and enhance the stability and accuracy of subsequent processing.

[0093] It should be noted that, even when the drill shaft 115 does not drill a hole at the center of the workpiece, the horn 114 can be pushed by a T-shaped plate 223 to rotate to the other side and contact the side wall of the T-shaped plate 223 on the other side.
