Description

Technical Field

[0001] This utility model relates to the field of boring and milling machine technology, and in particular to a centering device for a vertical milling and boring machine. Background Technology

[0002] A vertical milling and boring machine centering device disclosed in Chinese Patent CN221474481U includes a signal receiver mounted on a fixed block and a camera and a vertical signal transmitter mounted on a mounting plate. By setting the corresponding signal transmitter and receiver, precise centering between the workpiece clamping position and the cutting tool can be achieved. Simultaneously, the camera monitors the position of the signal receiver, enabling it to align with the transmitter more quickly and accurately. However, this vertical milling and boring machine centering device, while solving the problem, has the following drawbacks:

[0003] During the machining process, coolant needs to be sprayed continuously. When the coolant comes into contact with the high-speed rotating tool, it splashes everywhere, which will splash onto the surface of the tool signal receiver. The coolant may even carry debris and stick to the surface of the signal receiver, which will seriously affect the normal signal reception of the signal receiver and thus affect the accuracy of the alignment. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0005] Therefore, one objective of this utility model is to provide a centering device for a vertical milling and boring machine, which aims to solve the problem that the surface of the signal receiver in the existing vertical milling and boring machine centering device is easily contaminated with coolant and debris, affecting the normal reception of signals and thus affecting the centering accuracy.

[0006] To achieve the above objectives, one embodiment of this utility model provides a centering device for a vertical milling and boring machine, comprising a base, a bracket fixedly connected to one side of the top of the base, a milling and boring device fixedly mounted on the top of the bracket, a support fixedly connected to one side of the top of the bracket, a vertical signal transmitter and a camera fixedly mounted below the support, a worktable movably connected to the top of the base, a fixed clamping plate fixedly connected to one side of the top of the worktable, a first cylinder fixedly mounted on the other side of the top of the worktable, a movable clamping plate fixedly connected to the piston rod end of the first cylinder, a mounting base fixedly connected to one side of the fixed clamping plate, a signal receiver fixedly mounted on the top of the mounting base, a protective cover with a top opening fixedly connected to the top of the mounting base, a baffle hinged to one side of the top of the protective cover, a rocker arm fixedly connected to the side of the baffle near the protective cover, a sliding groove formed on one side of the rocker arm, a second cylinder fixedly mounted on the top of the mounting base, a connecting block fixedly connected to the piston rod end of the second cylinder, a sliding rod fixedly connected to one side of the connecting block, and the sliding rod slidably connected inside the sliding groove.

[0007] The beneficial effects are as follows: Before machining parts, the second cylinder retracts, and the baffle rotates to an inclined state, blocking the top of the protective cover. Thus, when machining parts, splashing coolant and debris can be blocked by the inclined baffle and then slide down along the baffle, thus avoiding the problem of coolant and debris falling on the signal receiver. During the next machining alignment, the second cylinder extends, the slide rod rises, and the rocker arm can be pushed upward. At this time, the baffle rotates, so that the top of the signal receiver is unobstructed, and alignment can be performed. This avoids the problem of foreign objects on the surface of the signal receiver affecting the alignment accuracy.

[0008] Preferably, the top of the fixed clamp plate near the mounting base has a bevel.

[0009] The beneficial effects are as follows: when the baffle is tilted and blocks the top of the protective cover, when the parts are being processed, the coolant and debris splashing onto the baffle can slide down the baffle and land on the slope of the fixed clamping plate. They will then slide to both sides, thus avoiding the problem of debris accumulating on the fixed clamping plate and affecting the opening of the baffle, thereby improving practicality.

[0010] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0018] This utility model provides a centering device for a vertical milling and boring machine.

[0019] Example 1:

[0020] like Figure 1-2As shown, it includes a base 1, a bracket 11 fixedly connected to one side of the top of the base 1, a milling and boring device 12 fixedly mounted on the top of the bracket 11, a support 13 fixedly connected to one side of the top of the bracket 11, a vertical signal transmitter 14 and a camera 15 fixedly mounted below the support 13, a worktable 2 movably connected to the top of the base 1, a longitudinal control box 4 fixedly connected to the top of the base 1, a transverse control box 5 slidably connected to the top of the longitudinal control box 4, and two sliding plates 51 fixedly connected to the bottom of the transverse control box 5, which slidably connect to both sides of the longitudinal control box 4. Furthermore, the longitudinal control box 4 is equipped with a longitudinal motor 41 capable of controlling the longitudinal sliding of the slide plate 51, thus enabling the longitudinal control box 4 to control the longitudinal sliding of the transverse control box 5. The worktable 2 is laterally slidably connected to the top of the transverse control box 5. A transverse motor 52 capable of controlling the transverse sliding of the worktable 2 is provided on one side of the transverse control box 5, thus enabling the transverse control box 5 to control the longitudinal sliding of the worktable 2. The cooperation of the longitudinal control box 4 and the transverse control box 5 allows the worktable 2 to move above the base 1. A fixed clamping plate 21 is fixedly connected to one side of the top of the worktable 2. On the other side, a first cylinder 22 is fixedly installed. A movable clamping plate 23 is fixedly connected to the piston rod end of the first cylinder 22. When the first cylinder 22 extends, it drives the movable clamping plate 23 to move closer to the fixed clamping plate 21, thereby clamping and fixing the components. A mounting base 24 is fixedly connected to one side of the fixed clamping plate 21. A signal receiver 25 is fixedly installed on the top of the mounting base 24. A protective cover 3 with a top opening is fixedly connected to the top of the mounting base 24. The top opening allows the vertical signal transmitter 14 to transmit signals into the signal receiver 25. A baffle 31 is hinged to one side of the top of the protective cover 3. A rocker arm 32 is fixedly connected to one side of the protective cover 3. A groove 33 is provided on one side of the rocker arm 32. A second cylinder 34 is fixedly installed on the top of the mounting base 24. A connecting block 35 is fixedly connected to the piston rod end of the second cylinder 34. A sliding rod 36 is fixedly connected to one side of the connecting block 35. The sliding rod 36 is slidably connected inside the groove 33. When the second cylinder 34 extends, it drives the sliding rod 36 to rise, thereby pushing the rocker arm 33 upward. At this time, the baffle 31 rotates, so that the signal receiver 25 is unobstructed above. Conversely, the baffle 31 blocks the signal receiver 25 from above.

[0021] It should be noted that both the longitudinal control box 4 and the transverse control box 5 are existing technologies, and their internal structures have been disclosed in a vertical milling and boring machine centering device disclosed in Chinese patent CN221474481U.

[0022] Example 2:

[0023] like Figure 3As shown, based on Embodiment 1, the top of the fixed clamping plate 21 near the mounting base 24 is provided with a slope angle 26. When the baffle 31 is tilted and blocks the top of the protective cover 3, when the parts are processed, the coolant and debris splash onto the baffle 31 and can slide down along the baffle 31. After landing on the slope angle 26 on the fixed clamping plate 21, they will slide to both sides, thereby avoiding the problem of debris accumulating on the fixed clamping plate 21 and affecting the rotation and opening of the baffle 31.

[0024] The working principle of this utility model is as follows: During alignment, the second cylinder 34 extends and the slide rod 36 rises, thereby pushing the rocker arm 33 upward. At this time, the baffle 31 rotates, so that there is no obstruction above the signal receiver 25, and the alignment operation can be performed. The signal emitted by the vertical signal transmitter 14 can be received by the signal receiver 25. After alignment is completed, the second cylinder 34 retracts and the baffle 31 rotates to an inclined state to block the top of the protective cover 3. When processing parts, the splashed coolant and debris can be blocked by the inclined baffle 31 and then slide down along the baffle 31, thereby avoiding the problem of coolant and debris falling on the signal receiver 25.
