Description

Technical Field

[0001] The invention relates to the technical field of machining machine tools, in particular to a sawing and milling integrated device. Background Art

[0002] A sawing and milling machine is a machine tool that uses a high-speed rotating milling cutter to process objects. The object is cut by moving the sawing and milling cutter and processing the object. The cutting efficiency is high and the cutting shapes are diverse. It can also achieve sawing and milling at the same time, and the incision is smoother.

[0003] The current integrated sawing and milling equipment realizes CNC automatic feeding through multi-axis linkage, improves processing accuracy and efficiency, avoids human participation in the processing and feeding process, greatly reduces the probability of operator injury, and effectively ensures the personal safety of operators.

[0004] However, when the current equipment is in use, the object to be processed needs to extend from one side of the mobile platform to form an extended end, and the extended end is in a suspended state. During the processing, when the cutting length of the object increases, the extended end tends to tilt downward, causing uneven force on the saw and milling cutter.

[0005] In the prior art, a pad is provided under the saw milling cutter, and the pad contacts the lower surface of the protruding end to provide support for the protruding end. However, on the one hand, the range of the pad is limited. If the length of the pad is increased, the load on the machine head will increase, and the occupied space of the machine will be increased. On the other hand, it is inconvenient to control the distance between the pad and the lower surface of the protruding end. When the pad is higher than the lower surface of the protruding end, the friction between the pad and the object increases, which will increase the resistance of the machine head during operation. When the pad is lower than the lower surface of the protruding end, the protruding end is still in a suspended state. On the third hand, processing debris is easily accumulated between the pad and the lower surface of the protruding end. When too much debris accumulates, it will also increase the resistance of the machine head during operation. Summary of the invention

[0018] (1) The sawing and milling processing equipment is provided with a support frame and mounted on a chain. The chain rotates around a sprocket and moves synchronously with the support frame.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0039] According to the following Figure 1 - Fig.14 A sawing and milling integrated device provided by an embodiment of the present invention is described.

[0040] See also Figure 1-Figure 4The embodiment of the present invention provides a technical solution: a sawing and milling processing integrated equipment, including a body 1, a mobile platform 2 and a head 7. In the existing technology center, the mobile platform 2 is used to carry the object to be processed and is slidably installed on the upper surface of the body 1. The head 7 is slidably installed on the side of the body 1. A sawing and milling cutter 41 is installed on the side of the head 7 close to the body 1. The sawing and milling cutter 41 is used to cut the object to be processed. When in use, the sliding direction of the mobile platform 2 is perpendicular to the sliding direction of the head 7. Usually, a clamping mechanism and a pressing mechanism are also provided. The clamping mechanism includes a mounting frame 3 and a clamping head 4. The mounting frame 3 is slidably arranged on the upper surface of the mobile platform. The clamping head 4 is fixed on the mounting frame 3. The object to be processed can be fixed on the mobile platform 2 through the clamping mechanism. The pressing mechanism is arranged on the side of the mobile platform 2 close to the head 7, including a beam 5 fixed on the mobile platform 2 and a pressing head 6 installed on the beam 5. The pressing head 6 can be controlled by a cylinder to press one end of the object to be processed to avoid shaking of the object during cutting.

[0041] It also includes a pad 8, which is fixedly mounted on the machine head 7 and close to the lower end of the saw milling cutter 41. The lower end of the saw milling cutter 41 passes through the pad 8 and is fixedly connected to the output end of the second motor 40 below, so that there is a gap between the upper surface of the pad 8 and the upper surface of the moving platform 2. When the object to be processed extends from one side of the moving platform 2 to form an extended end, the pad 8 can pre-support the extended end. The pre-support here means that when the downward deformation of the extended end is less than the height of the gap, the pad 8 does not contact the extended end. When the downward deformation of the extended end is greater than the height of the gap, the pad 8 can support the extended end. After the extended end completes cutting, the processed object is separated from the object to be processed and supported by the pad 8.

[0042] Preferably, the gap between the upper surface of the pad 8 and the upper surface of the mobile platform 2 is 2 mm to 10 mm.

[0043] In addition, it also includes a support frame, which is provided with multiple support frames. The multiple support frames are evenly distributed on both sides of the pad 8 and move synchronously with the random head 7. The top of the support frame is composed of a top plate 21, and the upper surface of the top plate 21 is flush with the upper surface of the pad 8, so that the multiple support frames and the pad 8 can jointly pre-support the protruding end, thereby increasing the pre-support area.

[0044] In addition, a plurality of support balls 20 are installed inside the support frame, and a through slot 211 is provided on the top plate 21. The upper portion of the support ball 20 passes through the through slot 211, and the middle and lower portions of the support ball 20 are still inside the support frame, thereby preventing the support ball 20 from being separated from the support frame through the through slot 211. At the same time, the top of the support ball 20 is higher than the upper surface of the moving platform 2, and the top of the support ball 20 contacts the bottom surface of the protruding end to support the object to be processed, and the bottom surface of the protruding end is in contact with the upper surface of the support frame and the pad 8. There is a certain buffer distance between the surfaces, and a single support ball 20 can move elastically in the vertical direction to adjust the supporting force of the object to be processed, to avoid excessive pressure between the support ball 20 and the protruding end, which leads to increased resistance between the support ball 20 and the protruding end, or insufficient pressure between the protruding end and the support ball 20, to provide supporting force for the protruding end, and at the same time, the support ball 20 can rotate in all directions, so that the support ball 20 is in rolling contact with the lower surface of the object to be processed, further reducing the friction between the support ball 20 and the protruding end.

[0045] In this embodiment, the distance between the top of the support ball 20 and the upper surface of the moving platform 2 is preferably 2 mm to 5 mm. If the distance is too small, the supporting force of the support ball 20 on the protruding end is insufficient. If the distance is too large, the support ball 20 may cause the protruding end to tilt upward, resulting in increased friction between the saw milling cutter 41 and the object to be processed, thereby increasing the risk of tool breakage.

[0046] Combination Figure 1 and Figure 2 In order to make the support frame play a pre-supporting role without affecting the horizontal movement of the head 7, chains 101 are provided at both ends of the support frame along the length direction. The chain 101 is in the shape of a runway as a whole. Sprockets 10 are provided at both ends of the fuselage 1 close to the head 7. The chain 101 is meshed with the sprocket 10. Brackets 9 can be provided on both sides of the sprocket 10, and the sprocket 10 is rotatably installed on the brackets 9, so as to fix and support the sprocket 10 and the chain 101, and a disconnection portion is provided on the upper side of the chain 101. The disconnection portion means that the chain 101 is not connected together on the upper side. Instead, it is in a disconnected state, so that the two sides of the machine head 7 at the pad 8 are fixedly connected to the disconnected part, thereby compensating the disconnected part of the chain 101 through the pad 8, and then when the machine head 7 moves, it drives the chain 101 to rotate around the sprocket 10, and at the same time drives the supporting frame to move. The specific fixing method can be that a connecting block 49 is fixedly provided at the end of the chain 101 closest to the pad 8, and the other end of the connecting block 49 is fixedly connected to the supporting frame closest to the pad 8, and the side of the fixed frame close to the machine head 7 is fixedly connected to the machine head 7, so that the machine head 7 is fixedly connected to the chain 101 at the pad 8.

[0047] Optionally, a driving device may be fixedly installed at the axis center of the sprocket 10 to drive the sprocket 10 to rotate through the driving device, and ensure that the chain 101 moves synchronously with the machine head 7, thereby avoiding increasing the power required for the movement of the machine head 7 and reducing the load on the machine head 7.

[0048] In addition, in order to prevent the lower side of the chain 101 from being blocked by the machine head 7, a clearance frame 33 is provided at the machine head 7 where the lower side chain 101 is located. The clearance frame 33 has a U-shaped structure, and the open end faces the fuselage 1. The height between the upper and lower inner walls of the clearance frame 33 is greater than the thickness of the support frame body, so as to facilitate the chain 101 and the support frame body to pass through the clearance frame 33.

[0049] In this embodiment, the chain 101 is integrally in a runway shape. The chain 101 in the runway shape is arranged around the sprocket 10. The chain 101 at the upper end of the sprocket 10 is the upper side, and the chain 101 at the lower end of the sprocket 10 is the lower side.

[0050] Combined Figure 4 - Figure 8 In order to facilitate the installation of the support ball 20, the support frame body further includes side plates 23 fixed to both ends of the top plate 21. A bottom plate 24 is fixedly installed between the bottom ends of the side plates 23. Both sides of the bottom plate 24 are fixed to the chain 101, so as to fix the support frame body between the two chains 101. The bottom plate 24 and the chain plate of the chain 101 can be fixed by welding or screws, or can be integrally formed with the chain plate.

[0051] In addition, in order to enable the support ball 20 to rotate万向ly within the support frame body, a plurality of side contact balls 22 are rotatably installed on the inner wall of each through groove 211. The side contact balls 22 can be rotatably installed on the inner wall of the through groove 211 through a rotating shaft, so that the side contact balls 22 are in rolling contact with the support ball 20. The plurality of side contact balls 22 enable the support ball 20 to be in force balance in the horizontal direction. Here, the force balance means that when the support ball 20 is in contact with the plurality of side contact balls 22 at the same time, it will not tilt in the horizontal direction. Specifically, when the through groove 211 is square, four side contact balls 22 are provided and distributed on the four inner walls of the through groove 211.

[0052] In addition, in order to support the bottom of the supporting ball 20, an elastic plate 27 is provided between the top plate 21 and the bottom plate 24. The two sides of the elastic plate 27 are respectively connected to the two side plates 23. The elastic plate 27 can be directly fixed on the side plates 23. The elastic plate 27 is rotated toward the surface of one side of the supporting ball 20 to provide a plurality of bottom edge contact balls 26. In fact, the bottom edge contact balls 26 have the same structure and size as the side contact balls 22, but are located in different positions. The plurality of bottom edge contact balls 26 correspond to the supporting balls 20 one by one, and the bottom edge contact balls 26 are in rolling contact with the supporting balls 20 to resist the balls 20. When the supporting balls 20 move downward, the corresponding part of the elastic plate 27 will be pressed downward. The reason why a rigid plate is not used as a support is to avoid the movement of a single supporting ball 20 driving the entire elastic plate 27 to move downward, thereby causing the remaining supporting balls 20 to move, thereby reducing the influence of a single supporting ball 20 on the remaining supporting balls 20 to improve the stability of the support.

[0053] Optionally, the elastic plate 27 can also be movably installed on the side plate 23. Specifically, connecting columns 271 are fixed on both sides of the elastic plate 27, a pill-shaped hole 231 is opened on the side plate 23, and the connecting column 271 is passed through the pill-shaped hole 231. When the elastic plate 27 is pressurized, the connecting columns 271 on both sides will move downward along the pill-shaped hole 231 under the action of pressure. This fixing method can reserve a buffer distance for the elastic plate 27, thereby increasing the service life of the elastic plate 27.

[0054] In addition, in order to prevent the support ball 20 from detaching from the support frame from the bottom of the top plate 21, a limit plate 25 is provided between the elastic plate 27 and the top plate 21. In order to improve the fixing strength of the limit plate 25, a connecting screw 212 can be driven into the top plate 21 and connected to the limit plate 25. A plurality of connecting screws 212 can be provided to improve the connection strength. The limit plate 25 is located at the lower half of the support ball 20 to avoid contact with the maximum diameter of the support ball 20, and the two sides of the limit plate 25 are respectively fixed to the side plates 23. A plurality of docking grooves 251 are provided on the limit plate 25, and the plurality of docking grooves 251 correspond to the support ball 20 one by one. The diameter of the docking groove 251 is larger than the diameter of the support ball 20 at the docking groove 251 (such as Figure 8 As shown in FIG. 2 , the support ball 20 is limited by the docking groove 251 after moving toward the limiting plate 25 by a specified distance, thereby preventing the support ball 20 from being separated from the support frame.

[0055] In this embodiment, the spherical side contact balls 22 and bottom contact balls 26 are used to reduce the contact area with the support balls 20, thereby reducing the friction between the support balls 20 and the support balls 20, so as to facilitate the rotation of the support balls 20.

[0056] Combination Figure 4-Figure 6In order to further realize elastic support for the support ball 20, a wavy spring piece 28 is provided between the elastic plate 27 and the bottom plate 24. The top end of the wavy spring piece 28 contacts the elastic plate 27, and the bottom end of the wavy spring piece 28 contacts the bottom plate 24. When the elastic plate 27 moves downward under pressure, the wavy spring piece 28 will be squeezed, so that the wavy spring piece 28 extends to both sides. After the pressure disappears, the wavy spring piece 28 returns to its initial state.

[0057] In addition, guide rods 30 are provided on both sides of the wavy spring piece 28. A sliding block 29 is slidably provided at one end of the guide rod 30 close to the wavy spring piece 28. Preferably, two guide rods 30 are provided to balance the force on the sliding block 29. A spring 31 is provided between the sliding block 29 and the side plate 23, and the spring 31 is sleeved on the outer peripheral surface of the guide rod 30. When the wavy spring piece 28 is compressed, it pushes the sliding block 29 to move toward the side plate 23 and squeezes the spring 31 at the same time, thereby improving the bearing capacity of the support ball 20 through the wavy spring piece 28 and the spring 31.

[0058] Combination Fig. 9 - Fig.11 In order to support the support frame, a lower support plate 11 is provided on the lower side of the chain 101. The lower support plate 11 is arranged along the moving direction of the machine head 7 and passes through the yield frame 33. One side of the lower support plate 11 is fixedly connected to the fuselage 1, and the lower support plate 11 suspends the lower side of the chain 101 to prevent the lower side of the chain 101 from sagging and pulling the upper side.

[0059] In addition, a first upper support plate 12 and a second upper support plate 13 are provided on the upper side of the chain 101, and the saw milling cutter 41 is located in the gap between the first upper support plate 12 and the second upper support plate 13, so that when the machine head 7 moves, the saw milling cutter 41 can move in the gap, and the first upper support plate 12 and the second upper support plate 13 are located in the same horizontal plane, and the upper surfaces of the two are flush, and a clearance hole 32 is provided on the side of the machine head 7 away from the fuselage 1, and the first upper support plate 12 passes through the clearance hole 32, and an avoidance portion 36 is provided on the side of the machine head 7 close to the fuselage 1, and the second upper support plate 13 passes through the avoidance portion 36.

[0069] In order to make the elastic plate 27 and the wavy spring piece 28 have sufficient elasticity and strength, the elastic plate 27 and the wavy spring piece 28 are preferably made of alloy steel, stainless steel or carbon steel to ensure that the support ball 20 maintains appropriate supporting force during long-term use.

[0070] When in use (working), the object to be processed is placed on the mobile platform 2, and one end of the object is fixed by the clamping mechanism, and then the position of the mobile platform 2 is adjusted to make a preliminary adjustment to the position of the object. After that, the clamping mechanism is moved to extend the other end of the object from one side of the mobile platform 2, and then the side of the object close to the extended end is pressed by the clamping mechanism, thereby completing the fixation of the object to be processed.

[0071] At this time, the support frame and the pad 8 are located below the protruding end. Multiple support frames are connected together by chains 101 and move together with the chain 101, and the support frames closest to the pad 8 on both sides are fixedly connected to the pad 8, so that when the head 7 moves, the support frame is driven to move synchronously. During the object processing, the support ball 20 is always in contact with the lower surface of the protruding end to support the protruding end. A single support ball 20 can rotate in all directions. When the pressure between the support ball 20 and the protruding end is too large, the support ball 20 will press the elastic plate 27 downward. The elastic plate 27 simultaneously applies pressure to the wavy spring sheet 28 below, so that the wavy spring sheet 28 stretches to both sides and pushes the sliding block 29 to squeeze the spring 31. When the pressure between the support ball 20 and the protruding end decreases, under the resetting action of the spring 31 and the wavy spring sheet 28, the support ball 20 moves upward, thereby realizing elastic support for the protruding end of the object to be processed.
