Description

Technical Field

[0001] This invention relates to the field of machine tool technology, specifically a gantry machining center. Background Technology

[0002] A machine tool is a device used to perform mechanical processing operations such as cutting, grinding, drilling, and boring on workpieces. In industrial production, it is often necessary to process large and complex workpieces. These workpieces usually have large dimensions and weight, and ordinary machine tools are difficult to meet the processing requirements. However, gantry machining tools can meet the needs of industrial production because they have high processing accuracy and efficiency and can perform a variety of complex processing operations.

[0003] In existing technologies, while existing gantry machining centers can perform high-precision machining on large and complex workpieces and ensure machining efficiency, they lack a cleaning function. When the gantry machining center is machining a workpiece, the coolant carries away the heat and debris generated during machining and then guides them away through the guide channels on the gantry machining center. However, these debris may accumulate inside the guide channels, which affects the flow effect of the coolant and thus the performance of the gantry machining center, reducing its service life and efficiency.

[0004] Therefore, we propose a gantry machining center to address the problems mentioned in the background section. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention, by setting an auxiliary mechanism, enables the gantry machining center to have an automatic cleaning function. During use, the gantry machining center can automatically clean its guide channels, ensuring the effective flow of coolant and thus improving its performance. This extends the service life and efficiency of the gantry machining center. When debris accumulates inside both guide channels and requires cleaning, the controller, two electric push rods, and two connecting plates work together to move both scrapers simultaneously until their surfaces contact the inner walls of the two guide channels. Then, the controller, the component controlling the movement of the machining table, the machining table itself, two connecting blocks, two auxiliary blocks, two hollow plates, two racks, two rotating rods, two first gears, two second gears, two motor bodies, two third gears, and two sealed bearings work together to move the two electric push rods simultaneously. Finally, the moving electric push rods, connecting plates, and scrapers work together to remove the debris from the guide channels corresponding to the two scrapers.

[0019] 2. In this invention, when the processing table moves to its maximum distance, the movement of the processing table can be stopped by the cooperation of the controller and the components that control the movement of the processing table. Then, by the cooperation of the controller, two drivers, two motor bodies, two connecting blocks, and two stabilizing blocks, the two third gears can be made to rotate simultaneously. Next, by the cooperation of the two third gears, two sealed bearings, two mounting holes, two rotating rods, and two second gears, the two first gears can be made to rotate simultaneously. Then, by the cooperation of the two first gears, two connecting blocks, two hollow plates, two rectangular slots, and two racks, the two auxiliary blocks can be made to move simultaneously. Finally, by the cooperation of the two electric push rods, two auxiliary blocks, two connecting plates, and two scrapers, the debris in the unprocessed parts inside the two guide channels can be scraped away.

[0020] 3. When the debris inside the two guide channels is completely cleaned, the two electric push rods can be reset to their original positions by using the controller, two drivers, and two motor bodies. Then, the two scrapers can be reset to their original positions by using the controller and the two electric push rods. Finally, the processing table can be reset to its original position by using the controller and the components that control the movement of the processing table.

[0021] 4. This invention, by setting up a processing mechanism, can achieve high-precision processing of large and complex workpieces while ensuring processing efficiency. When processing is required, the workpiece can be fixed on the processing table by using the processing table and the prepared fixture. Then, by using the controller, the pre-set operating program, the pre-set processing program, and the external power supply, the workpiece fixed on the processing table can be processed. At the same time, by using the controller, centrifugal pump, hose, prepared infusion pipe, prepared coolant storage tank, and flow guide, the heat generated during workpiece processing and the debris removed from the workpiece can be removed. Then, by using the flow guide channel, the coolant carrying heat and debris can be guided away.

[0022] 5. When a workpiece fixed on the processing table needs to move back and forth, the present invention utilizes the cooperation of the controller, the corresponding drive motor, the worktable, the corresponding mounting base, the corresponding bearing, the corresponding rotating shaft, the corresponding ball screw, the two first slide rails, the four first sliders, and the corresponding mounting block to drive the workpiece fixed on the processing table to move back and forth. When a tool mounted on the processing equipment needs to move left and right, the present invention utilizes the cooperation of the controller, the corresponding drive motor, the gantry, the two second slide rails, the four second sliders, the corresponding bearing, the corresponding mounting base, the corresponding rotating shaft, the corresponding ball screw, and the corresponding mounting block to drive the tool mounted on the processing equipment to move left and right.

[0023] 6. When the cutting tool mounted on the processing equipment needs to move up and down, the present invention can directly use the controller and the processing equipment to drive the cutting tool, centrifugal pump and guide to move up and down. When the workpiece finishes processing, the centrifugal pump can be turned off by the controller. At the same time, the previously moved parts can be reset to their initial positions by the controller, two drive motors and the processing equipment. When the previously moved parts have been reset to their initial positions, the two drive motors and the processing equipment can be turned off by the controller. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1 , Figure 2 , Figure 4 and Figures 6-10 As shown, the present invention provides a technical solution: a gantry machining center, including a machining mechanism 1, and an auxiliary mechanism 2 is provided on the machining mechanism 1;

[0037] The auxiliary mechanism 2 includes two connecting blocks 201, each containing an auxiliary block 202. Rectangular grooves 203 are formed on opposite sides of each auxiliary block 202, and racks 204 are fixed inside each rectangular groove 203. Hollow plates 205 are fixed to the bottom of each connecting block 201. Rectangular holes 206 are formed near the edges on opposite sides of each connecting block 201, and mounting holes 207 are formed at the top of the inner walls of each rectangular hole 206. Rotating rods 208 are rotatably connected to the interior of each mounting hole 207 via sealed bearings. Each of the two blocks is equipped with a first gear 209. A second gear 210 is fixedly sleeved on the outer surface of each of the two rotating rods 208 near the top. A stabilizing block 217 is fixedly fixed to the front surface of each of the two connecting blocks 201. A motor body 211 is mounted on the top of each of the two stabilizing blocks 217. A third gear 212 is fixedly sleeved on the outer surface of the output end of each of the two motor bodies 211. An electric push rod 213 is mounted on the bottom of each of the two auxiliary blocks 202 near the edge. A connecting plate 214 is mounted on the bottom of the telescopic end of each of the two electric push rods 213. A scraper 215 is mounted on the bottom of each of the two connecting plates 214. Drivers 216 are installed on opposite sides of block 201. Opposite sides of the two racks 204 contact the inner walls of the two connecting blocks 201 respectively. The tops of the two hollow plates 205 contact the bottoms of the two auxiliary blocks 202 respectively. Two first gears 209 are fixedly sleeved on the outer surfaces of the two rotating rods 208 respectively. The teeth of each first gear 209 mesh with the teeth of each rack 204. Each second gear 210 meshes with the teeth of each third gear 212. Two electric push rods 213 are slidably connected inside the two hollow plates 205 respectively. Two motor bodies... 211 is electrically connected to two drivers 216 respectively. The bottom ends of the two rotating rods 208 are respectively rotatably embedded in the bottom of the inner wall of the two rectangular holes 206. The processing mechanism 1 includes a worktable 101. Two symmetrical guide grooves 102 are opened on the upper side of the worktable 101. A processing table 105 is installed between the tops of the four first sliders 104. The opposite sides of the two connecting blocks 201 are respectively fixed to the two sides of the processing table 105. The surfaces of the two auxiliary blocks 202 are in contact with the surface of the processing table 105. The two electric push rods 213 and the two drivers 216 are electrically connected to the controller 116.

[0038] In this embodiment, when debris accumulates inside both guide channels 102 and needs to be cleaned, the controller 116 will simultaneously activate two electric push rods 213. Each activated electric push rod 213, in cooperation with the connecting plate 214, will drive the corresponding scraper 215 to move. When the surfaces of the two scrapers 215 contact the inner walls of the two guide channels 102, the controller 116 will simultaneously pause the two electric push rods 213. Subsequently, the controller 116 will control the movement of the processing table 105 by coordinating the components that move the processing table 105, causing the processing table 105 to move back and forth. Then, the moving processing table 105 will pass through the two connecting blocks 201, two auxiliary blocks 202, two hollow plates 205, and two racks 204. With the cooperation of two rotating rods 208, two first gears 209, two second gears 210, two motor bodies 211, two third gears 212, and two sealed bearings, two electric push rods 213 are driven to move simultaneously. The two simultaneously moving electric push rods 213, in cooperation with the connecting plate 214, drive the corresponding scrapers 215 to move inside the corresponding guide channels 102. When the two scrapers 215 move, each scraper 215 scrapes away the accumulated debris inside the corresponding guide channel 102. When the processing table 105 moves to its maximum distance, the controller 116 pauses the movement of the processing table 105. At this point, there is still a distance inside the two guide channels 102 that has not been processed. When the processing table 105 stops moving, the controller 116, through the cooperation of two drivers 216 (motor drivers), simultaneously starts two motor bodies 211. Each motor body 211, with the cooperation of its connected stabilizing block 217 and corresponding connecting block 201, drives its connected third gear 212 to rotate. Each rotating third gear 212, with the cooperation of its corresponding sealed bearing, corresponding mounting hole 207, corresponding rotating rod 208, and meshing second gear 210, drives its corresponding first gear 209 to rotate. Each rotating first gear 209, with the cooperation of its corresponding connecting block 201, corresponding hollow plate 205, corresponding rectangular groove 203, and corresponding rack 204... When the control is engaged, the corresponding auxiliary block 202 moves. Simultaneously, each moving auxiliary block 202, in conjunction with the connected electric push rod 213 and the corresponding connecting plate 214, moves the corresponding scraper 215. This uses the two moving scrapers 215 to remove debris from the unprocessed portions inside the corresponding guide channel 102. When all debris inside the two guide channels 102 is cleaned, the controller 116, two drivers 216, and two motor bodies 211 work together to reset the two electric push rods 213 to their original positions. Then, the controller 116 and the two electric push rods 213 work together to reset the two scrapers 215 to their original positions. Finally, the controller 116 works in conjunction with the components controlling the movement of the processing table 105.Simply reset machining table 105 to its original position.

[0039] Example 2: According to Figures 1-5 , Figure 8 and Figure 9 As shown, the processing mechanism 1 includes a worktable 101. Two symmetrical guide grooves 102 are formed on the upper side of the worktable 101. First slide rails 103 are installed in two recesses on the top of the worktable 101. Two first sliders 104 are slidably connected to each of the two first slide rails 103. A processing table 105 is installed between the tops of the four first sliders 104. A gantry frame 106 is installed on the top of the worktable 101. Mounting seats 107 are installed on the bottom inner wall of the worktable 101 and the surface of the gantry frame 106. Rotating shafts 108 are rotatably connected to the interior of each of the two mounting seats 107 via bearings. Drive motors 109 are installed on the bottom inner wall of the worktable 101 and the surface of the gantry frame 106. Ball screws 110 are installed at the output ends of each of the two drive motors 109. One end of the screw shaft of each ball screw 110 is fixed to one end of each of the two rotating shafts 108. A processing table 105 is installed on the top and surface of the gantry frame 106. The second slide rail 111 has two second sliders 112 slidably connected to each of the two second slide rails 111. A processing device 113 is installed between the outer surfaces of the two second sliders 112. A centrifugal pump 114 is installed near the bottom of the moving end surface of the processing device 113. A flow guide 115 is installed on the lower side of the moving end of the processing device 113. The inlet end of the flow guide 115 is connected to the outlet end of the centrifugal pump 114 through a hose. A controller 116 is installed on one side of the gantry 106. Multiple lifting rings 117 are installed on the top of the gantry 106 and the bottom of the inner wall of the worktable 101. Mounting blocks 118 are installed on the nut end surfaces of the two ball screws 110. The top of one mounting block 118 is installed with the bottom of the processing table 105, and the surface of the other mounting block 118 is installed with the surface of the processing device 113. The two drive motors 109, the processing device 113, and the centrifugal pump 114 are all electrically connected to the controller 116.

[0040] In this embodiment, when a workpiece needs to be processed, the workpiece is fixed directly on the top of the processing table 105. Then, the start button on the controller 116 is clicked. At this time, the controller 116 will process the workpiece fixed on the processing table 105 through the pre-set usage program, processing program, and external power supply. At the same time, the controller 116 will also start the centrifugal pump 114. When the centrifugal pump 114 starts, it will draw out the coolant from the storage tank with the help of the hose and the infusion tube, and then deliver it to the inside of the guide 115. Then, it will be guided to the workpiece being processed. When the coolant is guided to the surface of the workpiece being processed, the flowing coolant will carry away the heat generated during the workpiece processing and the debris processed from the workpiece. Then, the coolant carrying heat and debris will be directly guided into the two guide grooves 102 and then guided away. When the workpiece fixed on the processing table 105 needs to be moved back and forth (according to...) Figure 1 When the workpiece moves (as shown), the controller 116 will activate the corresponding drive motor 109. The activated drive motor 109, in conjunction with the worktable 101, the corresponding mounting base 107, the corresponding bearing, the corresponding shaft 108, the corresponding ball screw 110, the two first slide rails 103, the four first sliders 104, and the corresponding mounting block 118, will drive the workpiece fixed on the processing table 105 to move back and forth. When the tool mounted on the processing equipment 113 needs to move left or right (according to...), the workpiece will move accordingly. Figure 1 When the tool moves (as shown), the controller 116 will start the corresponding drive motor 109. The startled drive motor 109, in coordination with the gantry 106, the two second slide rails 111, the four second sliders 112, the corresponding bearings, the corresponding mounting base 107, the corresponding rotating shaft 108, the corresponding ball screw 110, and the corresponding mounting block 118, will drive the tool mounted on the processing equipment 113 to move left and right. When the tool mounted on the processing equipment 113 needs to move up and down (according to...), the tool will move accordingly. Figure 1 When the workpiece moves, the controller 116 will directly start the processing equipment 113. The started processing equipment 113 will directly drive the tool, centrifugal pump 114 and flow guide 115 mounted on it to move up and down. When the workpiece finishes processing, the controller 116 will first turn off the centrifugal pump 114. Then, through the cooperation of the two drive motors 109 and the processing equipment 113, the previously moved parts will be reset to their initial positions. When the previously moved parts have been reset to their initial positions, the controller 116 can then turn off the two drive motors 109 and the processing equipment 113.

[0041] The overall effect and working principle of the mechanism are as follows: When a workpiece needs to be processed, the lifting ring 117 and the prepared crane are used to install the entire gantry machining center in a suitable position. Then, the controller 116 is connected to an external power source via a prepared power cord. Next, the controller 116 is turned on, and the operating and processing programs are set. Then, the inlet of the centrifugal pump 114 is connected to the outlet of the coolant storage tank (the outlet of the storage tank is located near the bottom of the inner wall of the storage tank) via a prepared delivery pipe. Then, the cutting tool is fixed on the processing equipment 113. When everything is ready, the workpiece to be processed is fixed on the top of the processing table 105. Then, the start button on the controller 116 is pressed. At this time, the controller 116 will... The controller 116, in conjunction with the pre-set operating program, processing program, and external power supply, processes the workpiece fixed on the processing table 105. Simultaneously, the controller 116 activates the centrifugal pump 114. When the centrifugal pump 114 starts, it draws coolant from the storage tank using a hose and infusion pipe, then delivers it to the guide 115, and finally guides it onto the workpiece. As the coolant reaches the workpiece surface, it carries away the heat generated during processing and the debris removed from the workpiece. The coolant, carrying heat and debris, is then directly guided into the two guide channels 102 and then flowed away. When the workpiece fixed on the processing table 105 needs to be moved forward or backward (according to…),… Figure 1 When the workpiece moves (as shown), the controller 116 will activate the corresponding drive motor 109. The activated drive motor 109, in conjunction with the worktable 101, the corresponding mounting base 107, the corresponding bearing, the corresponding shaft 108, the corresponding ball screw 110, the two first slide rails 103, the four first sliders 104, and the corresponding mounting block 118, will drive the workpiece fixed on the processing table 105 to move back and forth. When the tool mounted on the processing equipment 113 needs to move left or right (according to...), the workpiece will move accordingly. Figure 1 When the tool moves (as shown), the controller 116 will start the corresponding drive motor 109. The startled drive motor 109, in coordination with the gantry 106, the two second slide rails 111, the four second sliders 112, the corresponding bearings, the corresponding mounting base 107, the corresponding rotating shaft 108, the corresponding ball screw 110, and the corresponding mounting block 118, will drive the tool mounted on the processing equipment 113 to move left and right. When the tool mounted on the processing equipment 113 needs to move up and down (according to...), the tool will move accordingly. Figure 1When the workpiece moves (as shown), the controller 116 will directly start the processing equipment 113. The started processing equipment 113 will then directly drive the tool, centrifugal pump 114, and flow guide 115 mounted on it to move up and down. When the workpiece finishes processing, the controller 116 will first shut down the centrifugal pump 114. Then, through the cooperation of the two drive motors 109 and the processing equipment 113, the previously moved parts will be reset to their initial positions. Once the previously moved parts have all returned to their initial positions, the controller 116 can then shut down the two drive motors 109 and the processing equipment 113. When debris accumulates inside both flow guide channels 102 and needs to be cleaned, the controller 116 will simultaneously start the two electric push rods 213. Each activated electric push rod 213, in cooperation with its connected connecting plate 214, drives the corresponding scraper 215 to move. When the surfaces of the two scrapers 215 contact the inner walls of the two guide channels 102 respectively, the controller 116 will simultaneously pause both electric push rods 213. Subsequently, the controller 116 will move the processing table 105 back and forth through the cooperation of the previously moved processing table 105 components. Then, the back-and-forth moving processing table 105 will be supported by two connecting blocks 201, two auxiliary blocks 202, two hollow plates 205, two racks 204, two rotating rods 208, two first gears 209, two second gears 210, two motor bodies 211, two third gears 212, and two sealed bearings. The controller 116 drives two electric push rods 213 to move simultaneously. These two moving electric push rods 213, in cooperation with the connecting plate 214, drive corresponding scrapers 215 to move inside their respective guide channels 102. As the two scrapers 215 move, each scraper 215 removes accumulated debris from inside its corresponding guide channel 102. When the processing table 105 reaches its maximum distance, the controller 116 pauses its movement. At this point, there is still some unprocessed space inside the two guide channels 102. When the processing table 105 stops moving, the controller 116, through the cooperation of two drivers 216 (motor drivers), simultaneously starts two motor bodies 211, and then... Each motor body 211, in cooperation with the stabilizing block 217 and the corresponding connecting block 201, drives the connected third gear 212 to rotate. Then, each rotating third gear 212, in cooperation with the corresponding sealed bearing, the corresponding mounting hole 207, the corresponding rotating rod 208, and the meshing second gear 210, drives the corresponding first gear 209 to rotate. Subsequently, each rotating first gear 209, in cooperation with the corresponding connecting block 201, the corresponding hollow plate 205, the corresponding rectangular groove 203, and the corresponding rack 204, drives the corresponding auxiliary block 202 to move. Simultaneously, each moving auxiliary block 202, in cooperation with the connected electric push rod 213 and the corresponding connecting plate 214,...The corresponding scraper 215 is moved, and the two moving scraper 215s scrape away the debris in the unprocessed parts inside the corresponding guide channel 102. When the debris inside both guide channels 102 is cleaned, the controller 116, the two drivers 216, and the two motor bodies 211 work together to reset the two electric push rods 213 to their original positions. Then, the controller 116 and the two electric push rods 213 work together to reset the two scraper 215 to their original positions. Finally, the controller 116 and the components that control the movement of the processing table 105 work together to reset the processing table 105 to its original position, after which the next workpiece processing operation can be performed.

[0042] Among them, sealed bearings, hoses, and bearings are commonly used parts in practice.

[0043] The processing equipment 113 mainly consists of a drive device (motor, servo electric cylinder, etc.), a spindle box (mainly including spindle, transmission system, bearing, etc.) and a slide (slide body, guide rail, transmission device, etc.). The simple principle is that the drive device drives the spindle box to move through the slide, and the spindle box, in cooperation with the drive device, drives the tool mounted on the spindle box to rotate at high speed to realize the processing operation of the workpiece.

[0044] The processing equipment 113 is electrically connected to the controller 116, mainly because the motor and servo electric cylinder of the driving equipment in the processing equipment 113 are electrically connected to the controller 116.

[0045] Among them, the drive motor 109, ball screw 110, processing equipment 113, centrifugal pump 114, controller 116 (PLC controller), motor body 211, electric push rod 213 and driver 216 are all existing technologies, and their working principles are all publicly available technologies. Their models can be selected according to actual conditions, and will not be explained in detail here.
