Description

Technical Field

[0001] This application relates to the field of composite machine tool technology, and in particular to a multi-axis composite machine tool for post-processing of lost foam castings. Background Technology

[0002] Lost foam casting is widely used in the automotive, aerospace and other fields because it can produce castings with complex shapes. However, after the castings are demolded, a lot of post-processing processes are still required, such as gating and riser removal, flash cleaning, surface finishing, drilling and punching. Therefore, composite machine tools are needed for processing.

[0003] Existing composite machine tools cannot simultaneously drill small holes and make large holes on workpieces during actual use. As a result, when drilling small holes and making large holes on workpieces is required, multiple operations are needed, which is inefficient and requires changing drill bits. To address these issues, this application proposes a multi-axis composite machine tool for post-processing of lost foam castings. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a multi-axis composite machine tool for post-processing of lost foam castings, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a multi-axis composite machine tool for post-processing of lost foam castings, comprising a frame, a mounting bracket mounted on the top of the frame, a connecting bracket slidably inserted into the inner wall of the mounting bracket, a fixing block mounted on the top of the connecting bracket, a servo motor fixedly mounted on the outer side of the fixing block, a lead screw fixedly connected to the power output shaft of the servo motor, a sliding frame threadedly connected to the outer edge of the lead screw, a transmission assembly mounted on the inner wall of the sliding frame, a movable frame slidably connected to the top of the frame, a placement frame mounted on the top of the movable frame, and a pressure rod and a positioning pin rotatably connected to the inner wall of the placement frame.

[0006] See Figure 1 and Figure 5 The top of the fixed block is provided with a track groove, and the bottom of the sliding frame is adapted to slide and connect to the inner wall of the track groove.

[0007] By adopting the above technical solution, the drive servo motor drives the lead screw to rotate, which can be used to move the sliding frame to slide on top of the fixed block, thereby adjusting the position of the transmission component and ensuring that the sliding frame will not shift its position during movement.

[0008] See Figure 1 and Figure 5The transmission assembly includes a stepper motor, which is mounted on the inner wall of the sliding frame. The power output shaft of the stepper motor is fixedly connected to a rotating shaft. A gear one is fixedly mounted on the outer edge of the rotating shaft. Gear two and gear three are symmetrically meshed on the outer edge of gear one. One end of a connecting rod is fixedly mounted on the inner wall of gear two. A drill bit is connected to the other end of the connecting rod. One end of a rotating rod is fixedly mounted on the inner wall of gear three. A hole opener is connected to the other end of the rotating rod.

[0009] By adopting the above technical solution, a stepper motor can be driven to rotate the shaft, which in turn can use gear one to drive gear two and gear three to rotate, and use the synchronous transmission connecting rod and rotating rod to drive the drill bit and hole opener to rotate, so as to realize synchronous drilling and hole punching operations on materials.

[0010] See Figure 1 and Figure 5 The outer wall of the sliding frame is equipped with a protective cover, and the inner wall of the protective cover is equipped with three ball bearings. The rotating shaft, connecting rod and rotating rod are all installed on the inner wall of the three ball bearings.

[0011] By adopting the above technical solution, the stability of the rotating shaft, connecting rod and rotating rod during rotation can be guaranteed, ensuring that they will not easily shift or sway in position during rotation.

[0012] See Figure 1 and Figure 5 The end of the pressure rod near the positioning pin has a slot, and the positioning pin is inserted into the inner wall of the slot.

[0013] By adopting the above technical solution, after the workpiece is placed on the inner wall of the placement rack, the pressure rod can be used to position the workpiece. At the same time, the positioning pin is rotated to the inner wall of the slot to lock the pressure rod and ensure that the pressure rod will not easily fall out of position.

[0014] See Figure 1 and Figure 5 The bottom of the mobile frame is fixedly equipped with a slide bar, and the top of the frame is provided with a guide groove, with the slide bar slidably connected to the inner wall of the guide groove.

[0015] By adopting the above technical solution, the slider can be used to limit the movement of the mobile frame when it is sliding on the top of the frame, ensuring its stability during sliding and preventing it from easily deviating from its position.

[0016] In a preferred embodiment, there are two mounting brackets and two connecting brackets, which are symmetrically arranged on the top of the frame, and cylinders are installed on the inner walls of both connecting brackets.

[0017] By adopting the above technical solution, the drive cylinder can push the moving frame to move at the top of the machine frame, which can then be used to move the workpiece.

[0018] The beneficial effects of this application are:

[0019] This multi-axis composite machine tool for post-processing of lost foam castings uses a stepper motor to drive a rotating shaft, which in turn drives gears two and three to rotate. This synchronous transmission connecting rod and rotating rod drive the drill bit and hole opener to rotate, thus realizing synchronous drilling and hole punching operations on the workpiece and improving work efficiency.

[0020] This multi-axis composite machine tool for post-processing of lost foam castings can drive a servo motor to rotate a lead screw, which can be used to move a sliding frame to slide on top of a fixed block, thereby adjusting the position of the transmission components and facilitating operation at different positions of the workpiece.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Reference Figure 1-5A multi-axis composite machine tool for post-processing of lost foam castings includes a frame 1, a mounting bracket 2 mounted on the top of the frame 1, a connecting bracket 3 slidably inserted into the inner wall of the mounting bracket 2, a fixing block 4 mounted on the top of the connecting bracket 3, a servo motor 5 fixedly mounted on the outer side of the fixing block 4, a lead screw 6 fixedly connected to the power output shaft of the servo motor 5, a sliding frame 7 threadedly connected to the outer edge of the lead screw 6, a transmission assembly mounted on the inner wall of the sliding frame 7, a movable frame 18 slidably connected to the top of the frame 1, a placement frame 19 mounted on the top of the movable frame 18, and a pressure rod 20 and a positioning pin 21 rotatably connected to the inner wall of the placement frame 19.

[0029] See Figure 3 The top of the fixed block 4 is provided with a track groove, and the bottom of the sliding frame 7 is adapted to slide and connect to the inner wall of the track groove, so that the drive servo motor 5 drives the lead screw 6 to rotate, which can be used to drive the sliding frame 7 to slide on the top of the fixed block 4, realize the adjustment of the position of the transmission component, and ensure that the sliding frame 7 will not shift its position during the movement.

[0030] See Figure 3 and Figure 4 The transmission assembly includes a stepper motor 8, which is mounted on the inner wall of the sliding frame 7. The power output shaft of the stepper motor 8 is fixedly connected to a rotating shaft 9. A gear 10 is fixedly mounted on the outer edge of the rotating shaft 9. Gears 11 and 14 are symmetrically meshed on the outer edge of gear 10. One end of a connecting rod 12 is fixedly mounted on the inner wall of gear 11. The other end of the connecting rod 12 is connected to a drill bit 13. One end of a rotating rod 15 is fixedly mounted on the inner wall of gear 14. The other end of the rotating rod 15 is connected to a hole opener 16, which allows the stepper motor 8 to drive the rotating shaft 9 to rotate. In turn, gears 11 and 14 can be driven by gear 10 to rotate, which is used to synchronously drive the connecting rod 12 and the rotating rod 15 to drive the drill bit 13 and the hole opener 16 to rotate, thereby realizing synchronous drilling and punching operations on materials.

[0031] See Figure 3 and Figure 4 The outer wall of the sliding frame 7 is equipped with a protective cover 17, and the inner wall of the protective cover 17 is equipped with three ball bearings. The rotating shaft 9, the connecting rod 12 and the rotating rod 15 are all installed on the inner wall of the three ball bearings, which can ensure the stability of the rotating shaft 9, the connecting rod 12 and the rotating rod 15 during rotation, and ensure that they will not easily shift or swing in position during rotation.

[0032] See Figure 5 The end of the pressure rod 20 near the positioning pin 21 has a slot. The positioning pin 21 is inserted into the inner wall of the slot, so that after the workpiece is placed on the inner wall of the placement rack 19, the pressure rod 20 can be used to position the workpiece. At the same time, the positioning pin 21 is rotated to the inner wall of the slot to lock the pressure rod 20 and ensure that the pressure rod 20 will not easily fall out of position.

[0033] See Figure 1 and Figure 5 A slide bar 22 is fixedly installed at the bottom of the movable frame 18, and a guide groove is provided at the top of the frame 1. The slide bar 22 is slidably connected to the inner wall of the guide groove, so that the slide bar 22 can be used to limit the movable frame 18 when it is sliding at the top of the frame 1, ensuring its stability during sliding and preventing it from easily deviating from its position.

[0034] See Figure 1 - Figure 2 There are two mounting brackets 2 and two connecting brackets 3, and the two mounting brackets 2 and two connecting brackets 3 are symmetrically arranged on the top of the frame 1. The inner wall of each of the two connecting brackets 3 is equipped with a cylinder 23, so that the driving cylinder 23 can push the moving frame 18 to move on the top of the frame 1, and thus can be used to realize the position movement of the workpiece.

[0035] Working principle: When using this device, the workpiece to be processed can first be placed inside the placement rack 19. Then, the pressure rod 20 is rotated to make it parallel to the placement rack 19. At the same time, the positioning pin 21 can be rotated to lock it onto the inner wall of the pressure rod 20. Then, according to the specifications of the workpiece, the drive cylinder 23 can be driven to push the moving frame 18 to move to the top of the frame 1. Then, the stepper motor 8 can be driven to drive the rotating shaft 9 to rotate. Then, the gear 10 can be used to drive the gear 2 11 and gear 3 14 to rotate, which is used to synchronously transmit the connecting rod 12 and the rotating rod 15 to drive the drill bit 13 and the hole opener 16 to rotate, realizing synchronous drilling and hole punching operations on the material, improving the efficiency of the operation. At the same time, the servo motor 5 can be driven to drive the lead screw 6 to rotate, which can be used to drive the sliding frame 7 to slide on the top of the fixed block 4, realizing the adjustment of the position of the transmission components, which can facilitate operation on different positions of the workpiece.
