Description

Technical Field

[0001] The utility model relates to the field of lathe processing, in particular to an automatic feeding device for a lathe used for processing hardware parts. Background Art

[0002] A lathe is a machine tool that mainly uses a turning tool to perform turning processing on a rotating workpiece. Drills, reamers, reamers, taps, dies and knurling tools can also be used on the lathe for corresponding processing. With the development and comprehensive application of electronic technology, computer technology and automation, precision machinery and measurement technologies, mechatronic automatic machine tools, also known as CNC machine tools, have emerged.

[0003] When existing automatic lathes process hardware and other parts, the hardware to be processed is generally loaded manually and fixed with a three-jaw chuck before the automatic lathe can be used to process it. The manual loading speed in this process is slow, and manual loading and fixing are required before each processing. Not only is the processing efficiency low, but it also increases the workload of workers and reduces overall practicality.

[0004] In summary, the above structure has a slow speed of manual loading during use, and requires manual loading and fixing before each processing, which not only reduces the processing efficiency but also increases the workload of workers and reduces the overall practicality. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an automatic feeding device for a lathe for processing hardware parts, so as to solve the technical problem that the manual loading speed is slow during use, which not only has low processing efficiency, but also increases the workload of workers and reduces the overall practicality.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic feeding device for a lathe for processing hardware parts, comprising a workbench, a three-jaw chuck is provided on the workbench, and a slide is installed on the other side thereof, a tailstock is slidably provided on the slide, and an insertion rod cooperating with the tailstock is slidably provided on one side of the slide, a slot is provided on the workbench at a middle position between the three-jaw chuck and the slide, and a loading turntable is rotatably provided in the slot, an array of through holes is evenly arranged at an eccentric position on the loading turntable, a guide column is slidably provided in the through hole, and a clamping suction cup is connected to the other end of the guide column.

[0007] By adopting the above technical solution, the tailstock is driven to slide to one side under the action of the slide. During this process, the insertion rod will move with the tailstock and be inserted into the through hole of the loading turntable, thereby driving the guide column to push upward. At the same time, the tailstock is limited and clamped by the cooperation of the tailstock and the three-jaw chuck. After the processing is completed, the tailstock is reset, and the processed workpiece will fall onto the loading turntable. At the same time, the insertion rod slides out of the through hole. At this time, the loading turntable rotates at a certain angle, and another group of workpieces to be processed are transferred to the three-jaw chuck, which is convenient for the staff to remove the processed workpieces.

[0008] The utility model is further configured such that compression springs are provided on both sides of the guide post on the loading turntable, and a slider is connected to the other end of the compression spring, and one side of the slider is connected to the guide post.

[0009] By adopting the above technical solution, when the insertion rod is inserted into the through hole, the guide column will be pushed upward by the action of the insertion rod. During this process, the slider will drive the compression spring itself to a stretched state. Then, when the insertion rod slides out of the through hole, the guide column loses the limiting force of the insertion rod. At this time, the compression spring will reset itself and drive the guide column to slide inward, so that the clamping suction cup will shrink to the loading turntable. At this time, the subsequent rotation of the loading turntable will not be affected by the slotting.

[0010] The utility model is further configured such that a plug rod is connected to one side of the tailstock, and a sliding groove for the plug rod to slide is provided on the slide.

[0011] By adopting the above technical solution, the insertion rod will be driven to move during the sliding process of the tailstock. Since the slide is provided with a slide groove, the insertion rod can be ensured to move in the horizontal direction during the sliding process of the tailstock.

[0012] The present invention is further configured such that guide post grooves are provided on the guide posts of the loading turntable, and a damping structure is provided on the contact surface between the guide post grooves and the guide posts.

[0013] By adopting the above technical solution, the cooperation between the guide post and the guide post groove facilitates the vertical movement of the guide post on the loading turntable. At the same time, the damping mechanism between the two prevents the guide post from shaking due to slight external vibrations.

[0014] The utility model is further configured such that a protective cover is provided on the inner side of the clamping suction cup, and the protective cover itself is provided in a rough shape.

[0015] By adopting the above technical solution, the protective cover can prevent the clamping suction cup from directly contacting the workpiece, reducing the wear of the workpiece itself. At the same time, the rough setting can prevent the workpiece from sliding a short distance in the clamping suction cup.

[0016] The present invention is further configured such that a driving component is provided on the workbench at the slot, and an output end of the driving component is connected to the loading turntable.

[0017] By adopting the above technical solution, the driving component is a stepper motor, which can drive the loading turntable to rotate a certain angle each time. At this time, it can be ensured that the clamping suction cup is on the horizontal line of the three-jaw chuck every time the loading turntable rotates.

[0018] The present invention is further configured such that the contact surface between the guide post and the insertion rod is arc-shaped.

[0019] By adopting the above technical solution, the arc-shaped setting makes it easier for the guide column to not limit and block the insertion rod when it is inserted into the through hole, thereby ensuring the stability of the guide column sliding up and down.

[0020] The present invention is further configured such that a plurality of supporting legs are provided at the bottom of the workbench.

[0021] By adopting the above technical solution, the device can be supported as a whole by the support legs, effectively reducing the impact of dust and stains on the workpiece to be processed.

[0022] In summary, the present invention has the following beneficial effects:

[0023] The loading turntable is rotated at a certain angle, and another group of workpieces to be processed are transferred to the three-jaw chuck, which is convenient for the staff to remove the workpieces after processing. In this process, the overall processing efficiency is accelerated and the loading burden of the staff is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] The following describes an embodiment of the present invention based on its overall structure.

[0031] Example 1

[0032] An automatic feeding device for a lathe used for processing hardware parts, such as Figures 1-4 As shown, it includes a workbench 1, a three-jaw chuck 2, a tailstock 3, a sliding mechanism, a clamping mechanism and a material-retrieving mechanism. A slot 6 is provided on the workbench 1 at the middle position between the three-jaw chuck 2 and the slide 4, and a loading turntable 5 is rotatably provided in the slot 6. The staff places the workpiece to be processed on the loading turntable 5, installs a slide 4 on one side of the workbench 1, and slides the tailstock 3 on the slide 4, and slides the insert rod 12 that cooperates with the tailstock 3 on one side of the slide 4. As the slide 4 drives the tailstock 3 to slide, the insertion rod 12 will also slide along with it, and a slot 6 is provided on the workbench 1 at a middle position between the three-jaw chuck 2 and the slide 4, and a loading turntable 5 is rotatably provided in the slot 6, and an array of through holes 9 are evenly provided at an eccentric position on the loading turntable 5. As the insertion rod 12 slides, the insertion rod 12 will be inserted into the interior of the through hole 9, because a guide post 10 is provided to slide in the through hole 9, and a clamping suction cup 7 is connected to the other end of the guide post 10;

[0033] When the workpiece is removed from the workpiece 10, the workpiece 10 will be moved back to the workpiece 10, and the workpiece 10 will be moved back to the workpiece 10, so that the workpiece 10 can be moved back to the workpiece 10.

[0034] See also Figure 1 and Figure 2 An insertion rod 12 is connected to one side of the tailstock 3, and a slide groove 8 for the insertion rod 12 to slide is provided on the slide 4. When the tailstock 3 slides, the insertion rod 12 will be driven to move. Since the slide groove 8 is provided on the slide 4, the insertion rod 12 is guaranteed to move horizontally during the sliding process of the tailstock 3.

[0035] See also Figure 3 A guide post groove 11 is provided at the guide post 10 on the loading turntable 5, and a damping structure is provided on the contact surface between the guide post groove 11 and the guide post 10. The cooperation between the guide post 10 and the guide post groove 11 facilitates the vertical movement of the guide post 10 on the loading turntable 5. At the same time, the damping mechanism between the two prevents the guide post 10 from shaking due to slight external vibrations.

[0036] Example 2

[0037] like Figure 3 The shown embodiment is an automatic feeding device for a lathe for processing hardware parts, and its overall structure is similar to that of Example 1, wherein compression springs 13 are provided on both sides of the guide post 10 on the loading turntable 5, and a slider 14 is connected to the other end of the compression spring 13, wherein one side of the slider 14 is connected to the guide post 10, and when the insertion rod 12 is inserted into the through hole 9, the guide post 10 will be pushed upward under the action of the insertion rod 12. During this process, the slider 14 will drive the compression spring 13 itself to be in a stretched state, and then when the insertion rod 12 slides out of the through hole 9, the guide post loses the limiting force of the insertion rod 12. At this time, the compression spring 13 itself will reset, driving the guide post 10 to slide inward, so that the clamping suction cup 7 will retract to the loading turntable 5, so that the subsequent rotation of the loading turntable 5 will not be affected by the slot 6.

[0038] When the workpiece is loaded onto the loading platform 5, the workpiece is sucked up by the clamping suction cup 7 and the workpiece is adsorbed by the clamping suction cup 7. At the same time, the slide table 4 drives the tailstock 3 to slide to one side. During this process, the tailstock 3 drives the insert rod 12 at one end to slide to one side. At the same time, the insert rod 12 is inserted into the through hole 9 of the loading platform 5, and the guide post 10 is made to slide upward and drive the clamping suction cup 7 to move upward. At this time, the tailstock 3 pushes the workpiece on the clamping suction cup 7 to move to the three-jaw chuck 2, and cooperates with the three-jaw chuck 2 to limit the clamping of the workpiece.

[0039] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
