Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pallet exchange mechanisms, specifically a pallet exchange mechanism for a horizontal machining center. Background Technology
[0002] Horizontal machining centers are high-precision, high-efficiency CNC machine tools primarily used for machining complex parts, especially suitable for workpieces requiring multi-faceted machining. Their spindles are horizontally arranged, and the worktable is typically rotatable, allowing multiple sides of the workpiece to be machined in a single setup. This reduces the number of setups and improves machining accuracy and efficiency. Horizontal machining centers are highly efficient and precise CNC machine tools suitable for multi-faceted machining of complex parts. Their core advantage lies in completing multiple machining operations in a single setup. Combined with automatic tool changers and pallet exchange functions, this significantly improves production efficiency and machining accuracy. They are widely used in aerospace, automotive manufacturing, mold making, and other fields, and are an indispensable piece of equipment in modern manufacturing.
[0003] After each workpiece on the pallet of the machining center is finished, the pallet needs to be pulled out and a new workpiece loaded on top for processing. This process stops the machining center while workpieces are being loaded, impacting processing efficiency. Therefore, we propose a pallet exchange mechanism for horizontal machining centers.

[0018] 1. In this utility model, when the entire exchange table slides to the end of the lifting plate, the slide table can be pulled back, and the exchange tray inside the machining center body can be processed by the machining center body. At this time, a clamp can be installed on the exchange tray on another set of slide tables to fix the new workpiece to be processed. After the workpiece inside the machining center body is processed, the empty slide table can be slid back to pull back the exchange tray of the processed workpiece, and then the processed workpiece can be moved away. The new workpiece to be processed can be pushed into the machining center body again in the above manner for processing. Through simple pulling and pushing, the entire exchange tray can be quickly changed, reducing the waiting time for changing trays and relatively improving processing efficiency.
[0019] 2. In this utility model, after the exchange table slides a certain distance, the folding rod aligns with the hole of the limit frame. The compressed torsion spring will spring back the folding rod. At this time, push the handle to make the rack drive the gear disk to rotate. When the gear disk rotates, the actuating groove on its surface will move the slide rod, and the slide rod will drive the push rod to push the locking block. The locking block will lock and fix the folding rod to prevent the exchange table from shaking during processing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-6A horizontal machining center pallet exchange mechanism includes a machining center body 1, with a control panel 4 disposed on the surface of the machining center body 1; it also includes an exchange section 2 for alternating workpieces within the machining center body 1; and a limiting section 3 for positioning the workpiece after exchange to prevent the machining center body 1 from shifting its machining position; the exchange section 2 includes a guide rail 21, which is fixedly connected to the surface of the machining center body 1, with a pulley 22 passing through the inner side of the guide rail 21, and a slide table 23 fixedly connected to one end of the pulley 22 located outside the guide rail 21; when the workpiece within the machining center body 1 is finished being processed, the empty slide table 23 can be slid and pulled back. After the workpiece is processed, the exchange tray 211 is moved aside, and the new workpiece to be processed is pushed into the machining center body 1 again in the same way. The entire exchange tray 211 can be quickly changed by simply pulling and pushing, which reduces the waiting time for changing trays and improves the processing efficiency. The top surface of the slide table 23 is fixedly connected to the fixing block 24, and the top surface of the fixing block 24 is provided with the anti-detachment plate 25. The inner surface of the machining center body 1 is fixedly connected to the connecting plate 26, and the inside of the machining center body 1 is fixedly connected to the fixing tray 27. The top surface of the fixing tray 27 is fixedly connected to the lifting plate 28. The surfaces of the anti-detachment plate 25, the connecting plate 26, and the lifting plate 28 are all equipped with rollers 212. The workpiece to be processed is placed on the exchange tray 211 and fixed with a clamp. Then, the handle on the fixing block 24 is pulled, so that the fixing block 24 drives the pulley 22 to slide in the guide rail 21 via the slide table 23. When the position of the anti-detachment plate 25 is aligned with the positions of the connecting plate 26 and the lifting plate 28, the exchange tray 211 can be pushed, so that the exchange platform 29 at the bottom of the exchange tray 211 slides along the rollers 212 provided on the surfaces of the anti-detachment plate 25, the connecting plate 26, and the lifting plate 28. The lifting plate 28 passes through the exchange table 29. The inner side of the exchange table 29 is provided with a groove 210. The top surface of the exchange table 29 is fixedly connected to the exchange tray 211. When the entire exchange table 29 slides to the end of the lifting plate 28, the slide table 23 can be pulled back, and the exchange tray 211 that enters the machining center body 1 can be processed by the machining center body 1. At this time, a fixture can be installed on the exchange tray 211 on another set of slide tables 23, and a new workpiece to be processed can be fixed.
[0031] The limiting part 3 includes a connecting rod 31, which is fixedly connected to the side of the exchange table 29. A folding rod 32 is hinged to the inner side of the connecting rod 31. When the exchange table 29 slides into the fixed tray 27 inside the machining center body 1, the folding rod 32 on the side of the exchange table 29 will fold against the edge of the limiting frame 34 and compress the torsion spring 33. After the exchange table 29 slides a certain distance, the folding rod 32 aligns with the hole in the limiting frame 34, and the compressed torsion spring 33 will spring back the folding rod 32. The torsion spring 33 is fixedly connected between the folding rod 32 and the connecting rod 31. The top surface of the fixed tray 27 is fixedly connected to the limiting frame 34. A fixed plate 35 is fixedly connected to the inner side of the limiting frame 34. A push rod 36 is slidably connected to the inner side of the fixed plate 35. A slide rod 37 is rotatably connected to the surface of the push rod 36. A clamping block 38 is fixedly connected to one end of the push rod 36 near the center of the fixed plate 35. A gear disk 39 is rotatably connected to the inner side of the limiting frame 34. A moving groove 310 is opened on the surface of the gear disk 39. A slide rod 37 passes through the moving groove 310. A rack 311 is slidably connected to the inner side of the limiting frame 34. When the gear disk 39 rotates, the moving groove 310 on its surface will move the slide rod 37. The slide rod 37 will drive the push rod 36 to push the locking block 38. The locking block 38 will lock and fix the folding rod 32 to prevent the exchange table 29 from shaking and meshing with the rack 311 and the gear disk 39 during processing. A handle 312 is fixedly connected to one end of the rack 311 located on the outside of the limiting frame 34.
[0032] In use, first place the workpiece to be processed on the exchange tray 211 and fix it with a clamp. Then pull the handle on the fixing block 24, so that the fixing block 24 drives the pulley 22 to slide within the guide rail 21 via the slide table 23. When the position of the anti-slip plate 25 is aligned with the positions of the connecting plate 26 and the lifting plate 28, the exchange tray 211 can be pushed, so that the exchange platform 29 at the bottom of the exchange tray 211 slides along the rollers 212 provided on the surfaces of the anti-slip plate 25, the connecting plate 26, and the lifting plate 28. When the entire exchange platform 29 slides to the end of the lifting plate 28, the slide table 23 can be pulled back, and the workpiece enters the machining center. The exchange tray 211 inside the machining center body 1 can be processed by the machining center body 1. At this time, a fixture can be installed on the exchange tray 211 on another set of slides 23 to fix the new workpiece to be processed. After the workpiece in the machining center body 1 is processed, the empty slide 23 can be slid to pull back the exchange tray 211 of the processed workpiece, and then the processed workpiece can be moved away. The new workpiece to be processed can be pushed into the machining center body 1 again for processing in the same way. The entire exchange tray 211 can be quickly changed by simply pulling and pushing, which reduces the waiting time for changing the tray and relatively improves the processing efficiency.
[0033] When the exchange table 29 slides into the fixed tray 27 inside the machining center body 1, the folding rod 32 on the side of the exchange table 29 will fold against the edge of the limit frame 34 and compress the torsion spring 33. After the exchange table 29 slides a certain distance, the folding rod 32 will align with the hole of the limit frame 34, and the compressed torsion spring 33 will spring back the folding rod 32. At this time, push the handle 312 to make the rack 311 drive the gear disk 39 to rotate. When the gear disk 39 rotates, the actuating groove 310 on its surface will actuate the slide rod 37, and the slide rod 37 will drive the push rod 36 to push the locking block 38. The locking block 38 will lock and fix the folding rod 32 to prevent the exchange table 29 from shaking during processing.
