Description

Technical Field

[0001] The invention relates to the field of compound boring and milling machine tools, in particular to a single-sided horizontal boring and fixed-beam gantry boring and milling compound machining center. Background Art

[0002] Boring and milling machines are a kind of processing tools commonly used in the processing industry. They combine the functions of boring machines and milling machines in one, making the processing efficiency higher and the precision better, greatly improving the product quality and labor efficiency. Gantry boring and milling machines have processing functions such as boring, drilling, milling, and grooving; equipped with high-precision rotary tables, right-angle milling heads and other functional accessories, they can achieve five-sided processing. They are ideal for processing large parts such as steam turbines, generators and heavy machinery in metallurgy, energy, and power industries.

[0003] At present, boring and milling processing of some special components requires the use of boring and milling tools in different directions for processing. For example, the end surface hole system of the motor base, the shaft end hole, each processing end surface, and each processing window need to be processed on different equipment. Using them in conventional boring and milling equipment requires frequent changes in the processing position. Therefore, in the prior art, such as patent CN113752029A, two boring and milling processing equipment of different dimensions are set on the basis of the original single-dimensional boring and milling equipment, so as to bore and mill components such as the motor base that need multi-position processing, thereby improving the processing efficiency. Setting up one more set of boring and milling equipment means that the overall length of the machine tool is longer. Considering the convenience of adjustment, the two sets of boring and milling equipment are usually set in a straight line with the processing table of the component, which will generate more debris during the processing. The longer linear guide rail will also make it difficult to clean the debris generated by boring and milling. It is necessary to manually clean the debris on the bottom slide rail of the boring and milling equipment, affecting the use of the equipment. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a single-sided horizontal boring and fixed-beam gantry boring and milling compound machining center to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. The entire linear slide table can be enclosed by a protective component to prevent debris from splashing during the boring and milling process. The debris is blown into the collection troughs on both sides of the slide table through the swinging blowing of the blowing component, and when the protective film is opened, the debris is pushed to one side to facilitate the cleaning of the debris on the slide table.

A second motor 414 is installed on the top of the vertical boring and milling device 1, and the second motor 414 drives the fan row 41 to swing back and forth. In this solution, the vertical boring and milling device 1 and the horizontal boring and milling device 2 are both installed on the slide rail table 5 through a slide seat and a cylinder to control their movement. The vertical boring and milling device 1 includes a vertical beam, a horizontal beam and a vertical boring and milling tool, which can adjust the horizontal and vertical positions. The boring and milling equipment 2 includes a vertical frame and a horizontal boring and milling tool, which can be adjusted in height. When using the device, the workpiece to be bored and milled is fixed on the placement table 51, and then the protective component 3 is used to enclose the two sides of the slide table 5. The vertical surface and horizontal surface of the workpiece are bored and milled by the vertical boring and milling equipment 1 and the horizontal boring and milling equipment 2. The debris generated by boring and milling is blown into the collection grooves 53 on both sides of the slide table 5 by the blowing component 4. When the protective film 32 is opened, the debris in the collection groove 53 is concentrated at one end.

[0030] In this embodiment, the protective component 3 also includes a winding shaft 31, and the end of the slide platform 5 away from the movable plate 35 is rotatably installed with the winding shaft 31 through a bearing seat and a torsion spring. The protective film 32 is wound on the winding shaft 31, and a screw rod is installed inside the slide frame 33, and a first motor 34 is fixed to the outer end of the slide frame 33. The first motor 34 is transmission-connected with the screw rod inside the slide frame 33, and the bottom of the movable plate 35 is engaged and sleeved on the screw rod and slides along the slide frame 33. The screw rod in the slide frame 33 is not shown in the figure.

In the process of retracting the protective film 32, the protective film 32 is retracted again by the torsion spring on the reeling seat of the winding shaft 31.

[0031] In this embodiment, a first gear 36 is rotatably mounted on the outer wall of the collecting trough 53 through a bearing, and a first transmission belt 37 is installed between adjacent first gears 36. The top of the first gear 36 is meshed with an upper tooth plate 39, and the bottom of the first gear 36 is meshed with a lower tooth plate 38, and the lower tooth plate 38 is fixed to the moving plate 35.

The first gears 36 are connected to each other through the first transmission belt 37 to make opposite movements. When the movable plate 35 moves along the slide frame 33 to unfold the protective film 32, the scraper 310 moves to the side of the collecting groove 53 close to the winding shaft 31. Similarly, when the movable plate 35 retracts the protective film 32, the upper tooth plate 39 and the lower tooth plate 38 move in the opposite direction. The upper tooth plate 39 drives the scraper 310 to move from one end of the collecting groove 53 to the other end, and the debris in the collecting groove 53 is pushed to one end of the collecting groove 53, so as to facilitate manual cleaning of the debris.

[0032] In this embodiment, the blowing assembly 4 also includes a telescopic frame 44, both ends of the cross bar 43 are fixed with the telescopic frame 44, and the bottom of the telescopic frame 44 is fixed to the outside of the sliding frame 33, the distance between the telescopic frame 44 and the side plate 52 is for the movable plate 35 to enter, and the storage end port of the telescopic frame 44 is meshed and plugged with a locking bolt 45, and the locking bolt 45 is in extrusion contact with the extended end of the telescopic frame 44, and the end of the rotating sleeve 42 close to the vertical boring and milling equipment 1 is fixedly sleeved with a second gear 46, and the top of the second gear 46 is meshed and connected with a third gear 47, and the top of the third gear 47 is meshed and connected with a fourth gear 48, and a connecting frame 49 is provided on the back of the third gear 47 and the fourth gear 48, and the other end of the connecting frame 49 is fixedly connected to the top of the telescopic frame 44, and the third gear 47 and the fourth gear 48 are both rotatably mounted on the connecting frame 49 through a bearing, and the fifth gear A mounting plate 412 is provided on the other side of the wheel 415, and a second transmission belt 411 is fixed on the surface of the mounting plate 412, and a pulley on one side of the second transmission belt 411 is connected to the fifth gear 415. Through the transmission of the second transmission belt 411, the telescopic rod 410 drives the fourth gear 48 to rotate, and the fourth gear 48 is meshed with the third gear 47. The third gear 47 is meshed with the second gear 46 to drive the rotating sleeve 42 and the fan row 41 to reciprocate and swing, so that the debris generated by the processing on the slide table 5 is blown into the collecting tank 53. The height of the fan row 41 can be adjusted by the telescopic frame 44 to cope with the boring and milling of workpieces of different sizes, and ensure that the rotation range of the fan row 41 can blow the debris on the slide table 5 and the workpiece surface into the collecting tank 53 (here the blowing range of the fan row 41 will not exceed the protective height of the protective film 32). When determining the height of the telescopic frame 44, it is locked by the locking bolt 45.

[0033] In this embodiment, a plug-in table 413 is slidably inserted at the top of the vertical beam of the vertical boring and milling equipment 1, and a second motor 414 is fixed on the plug-in table 413. Two fifth gears 415 are rotatably installed on the top of the plug-in table 413 through a bearing seat, and the two fifth gears 415 are meshed and connected. The output end of the second motor 414 is fixedly connected to the first gear 36 on one side, and a telescopic rod 410 is fixed at the axis of the fourth gear 48, and the other end of the telescopic rod 410 is connected to the pulley on the other side of the second transmission belt 411. The second motor 414 for driving the fan row 41 to swing back and forth is installed on the plug-in table 413 and is transmitted through the mounting plate 412 and the second transmission belt 411. Because the position of the plug-in table 413 can be maintained at a height close to that of the fan row 41 by the connecting frame 49 and the mounting plate 412, it is convenient to drive the fan row 41 to swing. When adjusting the height of the telescopic frame 44 and the height of the fan row 41, the plug-in table 413 is moved along The top of the vertical beam of the vertical boring and milling equipment 1 slides to maintain a height close to the fan row 41, and the second motor 414 drives the fifth gear 415 to engage and rotate. The second transmission belt 411 is installed on the mounting plate 412, and is transmitted to the second gear 46, the third gear 47 and the fourth gear 48 through the telescopic rod 410, thereby driving the fan row 41 to swing. The function of the telescopic rod 410 is that when the vertical boring and milling equipment 1 moves, the telescopic rod 410 can maintain the transmission connection between the fan row 41 and the second motor 414 (in this part, the connection between the rotating sleeve 42 and the cross bar 43 can be directly connected through a bearing rotation sleeve, or a sliding installation method can be adopted. The second gear 46 drives the rotating sleeve 42 to rotate, and the rotating sleeve 42 can also translate along the cross bar 43. When the vertical boring and milling equipment 1 moves beyond the storage length of the telescopic rod 410, it will push the rotating sleeve 42 to translate, thereby avoiding the fan row 41 from colliding with the vertical boring and milling equipment 1).

[0034] When the device is used, the workpiece to be bored and milled is fixed on the placement table 51, and the first motor 34 drives the screw to rotate, and the moving plate 35 engages with the screw to slide along the slide frame 33, pulling the protective film 32 to expand and block the sides of the two side plates 52 to prevent debris from falling. The vertical surface and the horizontal surface of the workpiece are bored and milled by the vertical boring and milling equipment 1 and the horizontal boring and milling equipment 2. The height of the fan row 41 can be adjusted by the telescopic frame 44, so as to cope with the boring and milling of workpieces of different sizes, ensuring that the rotation range of the fan row 41 can blow the debris on the slide table 5 and the workpiece surface into the collection tank 53. When determining the height of the telescopic frame 44, it is locked by the locking bolt 45, and the second transmission The transmission of belt 411 drives the telescopic rod 410 to rotate, and the fourth gear 48 is meshed with the third gear 47. The third gear 47 is meshed with the second gear 46 to drive the rotating sleeve 42 and the fan row 41 to swing back and forth, and the debris generated by the processing on the slide rail table 5 is blown into the collecting groove 53. When the protective film 32 is unfolded, the scraper 310 moves to the side of the collecting groove 53 close to the winding shaft 31. Similarly, when the movable plate 35 retracts the protective film 32, the upper tooth plate 39 and the lower tooth plate 38 move in the opposite direction, and the upper tooth plate 39 drives the scraper 310 to move along one end of the collecting groove 53 to the other end, and the debris in the collecting groove 53 is pushed to one end of the collecting groove 53, so as to facilitate manual cleaning of the debris.
