Description

Technical Field

[0001] The utility model relates to the technical field of loading and unloading equipment for vertical machining centers, and more specifically, to a front manual delivery table for a large vertical machining center. Background Art

[0002] At present, the automation of loading and unloading for known vertical machining centers is mainly robot automatic loading and unloading. Product fixtures and robot fixtures need to be customized according to products. Changing products for processing and debugging is rather cumbersome. In actual use, it can only process large quantities of products. Debugging small batches of parts takes a long time and is not very applicable. By using zero-point quick-change fixtures to quickly switch products, the quick switching of product fixtures can be achieved, but there are also its disadvantages. For some small and light fixtures of small products, manual quick loading and unloading can be carried out, while for heavy products, hoisting is needed for loading and unloading, with slow loading speed and troublesome operation. In actual use, the efficiency improvement is not high, and the labor intensity of operators cannot be reduced. Using robots for loading and unloading occupies a large area, has a high input cost, and requires high technical requirements for operators, resulting in long machine tool downtime. Summary of the Utility Model

[0003] In view of this, the utility model provides a front manual delivery table for a large vertical machining center.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A front manual delivery table for a large vertical machining center includes a machining center and a delivery table. The delivery table is arranged on the front side of the machining center. The delivery table includes a frame, and the frame is placed horizontally and closely abuts against the front of the machining center. At least two horizontal heavy-duty linear guides are arranged on the frame. Two loading tables connecting the heavy-duty linear guides are arranged on the frame, and the loading tables can move horizontally through the heavy-duty linear guides. The machining center is provided with a machining table. A tray carrier plate for fixing a product fixture is arranged on the loading table. A guide wheel frame capable of connecting the tray carrier plate is arranged on the loading table. A plurality of main guide wheels and side guide wheels are arranged on the guide wheel frame, and the tray carrier plate can be manually pushed and pulled away from or close to the loading table through the guide wheel frame.

[0006] In a preferred technical solution, fixing plates are respectively arranged on the left and right sides of the guide wheel frame. The plurality of main guide wheels and side guide wheels are installed on the fixing plates, and the main guide wheels contact the bottom surface of the tray carrier plate.

[0007] In a preferred technical solution, two limiting blocks corresponding to the fixing plates on both sides of the guide wheel frame are symmetrically arranged at the bottom of the tray carrier plate, and the inner side surfaces of the limiting blocks can contact the side guide wheels.

[0008] In the preferred technical solution, a support frame outer plate is provided on the side of the frame close to the processing table, a first guide wheel group is provided on the support frame outer plate, and a second guide wheel group is provided on the side of the processing table close to the delivery table. The pallet carrier can be pushed onto the processing table by the cooperation of the guide wheel frame, the first guide wheel group and the second guide wheel group.

[0009] In the preferred technical solution, the processing table is provided with a locking device which can lock and fix the tray carrier.

[0010] In the preferred technical solution, a plurality of foot cups are provided at the bottom of the frame for fixing the delivery platform to the ground.

[0011] In the preferred technical solution, positioning buckles are respectively provided in the center and on the left and right sides of the frame, and a locking handle that can cooperate with the positioning buckles is provided on the loading platform.

[0012] In a preferred technical solution, a first handle is provided on the guide wheel frame, and a second handle is provided on the tray carrier.

[0013] It can be seen from the above technical solutions that, compared with the prior art, the present invention has the following beneficial technical effects:

[0014] The delivery platform is set in front of the machining center. The lateral movement of the loading platform is achieved through heavy-duty linear guides. The guide wheel frame and guide wheel system simplify the pushing process of the pallet carrier. The operator only needs to push and pull the pallet carrier from the delivery platform to the machining table, which significantly reduces the loading time and improves the overall processing efficiency. The frame is placed horizontally, close to the front of the machining center, which does not affect the operation of personnel and reduces the floor space.

[0015] Two loading tables are set up on the delivery table. The operator can process on one loading table while preparing the next product to be processed on the other loading table, realizing the alternating operation of loading and unloading, reducing the downtime of the machining center, and is particularly suitable for the processing of small batches and multiple varieties of products.

[0016] The cooperation of heavy-load linear guides and guide wheel frames on the delivery platform makes the movement of the pallet carrier smoother and more stable. Operators only need to push and pull the handles to complete the loading operation, which significantly reduces labor intensity and avoids the tedious operation of manually carrying heavy workpieces.

[0017] The setting of the main guide wheel, side guide wheels and limit blocks on the guide wheel frame ensures the stable guidance of the pallet carrier, avoids the workpiece from shaking left and right during the pushing process, and ensures the precise positioning of the workpiece in the machining center.

[0026] A front manual delivery table for a large vertical machining center. Please refer to Figures 1-3 , which includes a machining center 100 and a delivery table 200. The machining center 100 is a large vertical machining center, which is provided with a box structure and a vertical machining spindle inside the box. The delivery table 200 is arranged on the front side of the machining center 100; the delivery table 200 includes a frame 210. The frame 210 is the main base of the delivery table 200. The frame 210 is placed horizontally and closely abuts against the front of the machining center 100. The fact that the frame 210 closely abuts against the front of the machining center 100 facilitates the operator to load the machining center 100 through the delivery table 200, which is convenient for operation and reduces the floor area. Two horizontal heavy-duty linear guides 220 are arranged on the frame 210. A loading table 230 that simultaneously connects the two heavy-duty linear guides 220 is arranged on the frame 210. The loading table 230 that simultaneously connects the two heavy-duty linear guides 220 can move horizontally on the frame 210. The loading table guided by the heavy-duty linear guide 220 has the advantages of large load and smooth movement, which is convenient for loading when machining larger workpieces.

[0027] Furthermore, the machining center 100 is provided with a machining table 110. The loading table 230 is provided with a pallet carrier plate 231 for fixing product jigs. The loading table 230 is provided with a guide wheel frame 240 that can be connected to the pallet carrier plate 231. The guide wheel frame 240 is provided with a plurality of main guide wheels 241 and side guide wheels 242. The pallet carrier plate 231 can be manually pushed and pulled away from or close to the loading table 230 through the guide wheel frame 240. The machining table 110 is arranged inside the housing of the machining center 100. A switchable cabinet door is provided at the position corresponding to the center of the frame 210 of the machining center 100. When machining products are loaded through the delivery table 200, one or more jigs matching the products to be machined are pre-set on the pallet carrier plate 231 of one of the loading tables 230. After the products are fixed on the jigs, the loading table 230 is manually moved horizontally to the position corresponding to the machining table 110. At this time, the cabinet door is opened. Then, through the action of the guide wheel frame 240, the operator can push the pallet carrier plate 231 into the housing of the machining center 100. After the pallet carrier plate 231 reaches the machining table 110, the loading is completed. Finally, the cabinet door of the machining center 100 is closed, and the products are processed in the machining center 100. During the processing, the pallet carrier plate 231 on the other loading table 230 can be placed to fix the products to be machined, facilitating the loading and processing of the second pallet carrier plate 231 after the products on the first pallet carrier plate 231 are processed and pulled out, reducing the downtime of the machining center 100. When the second pallet carrier plate 231 is pushed in for processing, the operator can remove the processed products on the first pallet carrier plate 231 and re-place the products to be machined for the next round of processing. The machining center 100 and the delivery table 200 of the present utility model are signal-connected together to realize the mutual control between the jigs in the machining center 100 and the delivery table 200. By adopting the function of alternately switching the loading and unloading of the two loading tables, the loading procedure only requires the operator to push and pull the loading table 230 for loading, reducing the labor intensity, optimizing the debugging time for switching products, and solving the complex phenomenon of debugging for small batches of multiple products.

[0028] Further, fixing plates 243 are respectively provided on the left and right sides of the guide wheel frame 240. A plurality of connecting bars are provided between the two fixing plates 243 to make the guide wheel frame 240 have better stability. A plurality of main guide wheels 241 and side guide wheels 242 are provided on the fixing plates 243. The main guide wheels 241 contact the bottom surface of the tray carrier plate 231. The tray carrier plate 231 moves in a direction away from or close to the workbench 110 through the rolling action of the main guide wheels 241. The main guide wheels 241 serve as the main guiding and moving structure of the tray carrier plate 231, facilitating the operator to push and pull the tray carrier plate 231 for loading and unloading. Two limiting blocks 232 corresponding to the fixing plates 243 on both sides of the guide wheel frame 240 are symmetrically provided at the bottom of the tray carrier plate 231. The limiting blocks 232 are formed with slots capable of accommodating the side guide wheels 242. The tray carrier plate 231 forms a fastening structure with the guide wheel frame 240 through the limiting blocks 232. The inner side surface of the limiting blocks 232 contacts the side guide wheels 242. The side guide wheels 242 form auxiliary guiding when the tray carrier plate 231 is pushed and pulled, and can reduce the left and right shaking of the tray carrier plate 231, making the pushing smoother.

[0029] Further, a support frame outer plate 250 is provided on one side of the frame 210 close to the processing table 110. A first guide wheel group 251 is provided on the support frame outer plate 250. A second guide wheel group 260 is provided on one side of the processing table 110 close to the delivery table 200. The tray carrier plate 231 can be pushed onto the processing table 110 through the cooperation of the guide wheel frame 240, the first guide wheel group 251, and the second guide wheel group 260. The structures of the first guide wheel group 251 and the second guide wheel group 260 are similar to that of the guide wheel frame 240 and also have two types of rollers, which can support and guide the movement of the tray carrier plate 231. The first guide wheel group 251 and the second guide wheel group 260 can be used as an extension of the guide wheel frame 240 in the direction of the workbench 110 to ensure that when the tray carrier plate 231 is pushed towards the processing table 110, it can still use the first guide wheel group 251 and the second guide wheel group 260 for guiding and sliding to smoothly reach the workbench 110 after leaving the guide wheel frame 240. A locking device 111 capable of locking and fixing the tray carrier plate 231 is provided on the processing table 110. When the tray carrier plate 231 reaches the processing table 110, after the machining center 100 receives a signal, it can automatically lock and fix the tray carrier plate 231 through the locking device 111. Subsequently, the tray carrier plate 231 can stably follow the movement of the processing table 110 for automatic processing. After the processing is completed and unlocked, the operator can pull out the tray carrier plate 231.

[0030] Furthermore, a plurality of leveling feet 211 for fixedly connecting the delivery table 200 to the bottom surface are provided at the bottom of the frame 210. Round holes are provided on the leveling feet 211. Screws are driven into the ground through the round holes on the leveling feet 211 to fix the entire delivery table 200 to the bottom surface, achieving high-stability independent loading. Positioning buckles 212 are respectively provided at the center and on the left and right sides of the frame 210. Slots are provided on the positioning buckles 212. A locking handle 233 that can be snap-fitted with the positioning buckle 212 is provided on the loading table 230. After the locking handle 233 is pulled down, the snap fit with the positioning buckle 212 is released, and the loading table 230 can be horizontally pulled left and right through the heavy-duty linear guide 220. When the loading table 230 reaches the positioning buckle 212, after the locking handle 233 is pulled up, the end of the locking handle 233 is inserted into the slot of the positioning buckle 212 and locked, making it impossible to move horizontally left and right, facilitating the positioning of the loading table 230 to ensure stable loading. A first handle 244 is provided on the guide wheel frame 240, and a second handle 2311 is provided on the tray carrier 231. Operators can push and pull the loading table 230 and the tray carrier 231 by holding the first handle 244 and the second handle 2311 respectively.
