Description

Technical Field

[0001] This utility model relates to the field of lathe machining technology, specifically to a workpiece machining lathe. Background Technology

[0002] Turning refers to machining on a lathe, which is a part of mechanical processing. Lathe machining mainly uses a cutting tool to turn rotating workpieces. Lathes are mainly used to machine shafts, discs, sleeves, and other workpieces with rotating surfaces, and are one of the most widely used types of machine tools in machinery manufacturing and repair shops.

[0003] Existing machining lathes, such as the utility model patent document with authorization announcement number "CN221247947U" and patent name "A Workpiece Machining Lathe", disclose a machining lathe including a machining lathe box and a lathe dust collection box. The lathe dust collection box is provided at the lower end of the machining lathe box, a lathe is provided inside the machining lathe box, exhaust holes are provided on both sides of the lathe dust collection box, and a dust absorption box is provided inside the lathe dust collection box.

[0004] The aforementioned patent document describes a process where the product is placed manually on the processing station, then cut by the cutting mechanism. After processing, the product is removed manually from the processing station. When using the lathe to process the product, both loading and unloading are done manually, resulting in low processing efficiency. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by proposing a workpiece machining lathe. This lathe addresses the problem mentioned in the background art, where the lathe mainly relies on manual placement of the product on the machining station, followed by cutting of the product by the cutting mechanism, and manual removal of the product from the machining station after machining. The manual handling of material handling and removal during product machining on the aforementioned lathe results in low processing efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A workpiece machining lathe includes a lathe body, a three-jaw chuck for clamping workpieces on one side of the lathe body, a guide rail fixedly mounted on the lathe body, a first slider slidably mounted on the guide rail, a cutting tool for turning the workpiece mounted on the first slider, a storage bin for storing workpieces on one side of the lathe body, a first pushing assembly for pushing the workpieces in the storage bin to the axis of the three-jaw chuck on the lathe body, a first electric push rod fixedly mounted on the lathe body, a second pushing assembly for pushing the workpieces on the first pushing assembly onto the three-jaw chuck on the telescopic end of the first electric push rod, a guide frame slidably mounted on one side of the lathe body and located below the three-jaw chuck, and the cutting tool located between the guide frame and the first pushing assembly.

[0008] Working principle:

[0009] The workpieces stacked in the storage bin fall to the top of the first jacking assembly under the influence of gravity. The first jacking assembly can push the rod-shaped workpiece at the bottom of the storage bin to the axis of the three-jaw chuck. At this time, the axis of the rod-shaped workpiece coincides with the axis of the three-jaw chuck. Then, the operator starts the first electric push rod, which drives the second jacking assembly to move towards the lathe body. When the second jacking assembly moves to the side where the workpiece is away from the three-jaw chuck, the operator starts the second jacking assembly, which can move the workpiece towards the three-jaw chuck. The three-jaw chuck can clamp the workpiece. After that, the first electric push rod returns to its original position. Then, the operator drives the first slider to move the cutting tool. The three-jaw chuck drives the workpiece to rotate, and the cutting tool performs rough machining on the workpiece. When the cutting tool is machining the workpiece, the guide frame is away from the lathe body and does not contact the first slider and the cutting tool. After the workpiece is finished, the guide frame moves towards the bottom of the three-jaw chuck, and the three-jaw chuck can push the finished workpiece outward. The workpiece falls onto the inclined guide frame and is exported outward.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] First, a first pushing component is provided, which can push the workpiece out of the storage bin, realizing the pushing of a single workpiece.

[0012] Secondly, a second pushing component is provided, which can push the rod-shaped workpiece on the first pushing component onto the three-jaw chuck and hold it in place. Thus, the second pushing component, in coordination with the first pushing component, can achieve continuous pushing from the storage bin to the processing position without manual intervention.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] Example:

[0019] like Figure 1 As shown, a workpiece machining lathe includes a lathe body 1, a three-jaw chuck 2 for clamping the workpiece is provided on one side of the lathe body 1, a guide rail 3 is fixed on the lathe body 1, a first slider 4 is slidably provided on the guide rail 3, and a cutting tool 5 for turning the workpiece is provided on the first slider 4. The three-jaw chuck 2 clamps the workpiece to be processed, and the first slider 4 carries the cutting tool 5 and moves along the guide rail 3 on the guide rail 3. The first slider 4 is driven by a drive mechanism (such as a lead screw or motor) and slides along the guide rail 3 to the workpiece processing position, where the cutting tool 5 cuts the workpiece.

[0020] A storage bin 6 for storing workpieces is provided on one side of the lathe body 1. Workpieces stacked in the storage bin 6 fall to the top of the push block 10 under gravity. The lathe body 1 is equipped with a first push assembly for pushing the workpieces in the storage bin 6 to the axis of the three-jaw chuck 2. The first push assembly includes a fixed frame 9, a push block 10, a placement block 11 for placing workpieces, a spring 12, and a mounting block 13. The fixed frame 9 is fixed to the lathe body 1, and the push block 10 is slidably mounted on the fixed frame 9. The bottom outlet of the storage bin 6 abuts against the top of the push block 10. The placement block 11 is rotatably mounted on the end of the push block 10 away from the fixed frame 9. The two ends of the spring 12 are fixed to the placement block 11 and the bottom of the push block 10, respectively. The mounting block 13 is fixed to the fixed frame 9, and the side of the mounting block 13 closest to the placement block 11 is inclined. The mounting block 13 is used for… When the push block 10 moves toward the fixed frame 9, it abuts against the placement block 11 and causes the placement block 11 to rotate. The push block 10 slides along the fixed frame 9 toward the lathe body 1. The inclined surface of the mounting block 13 gradually loses contact with the placement block 11. Since the placement block 11 is fixed with a counterweight near the bottom of the fixed frame 9, it is forced to rotate around the axis to a horizontal state. When the push block 10 pushes out, the spring 12 pushes the placement block 11 to rotate. When the push block 10 retracts, the spring 12 is compressed to avoid hard contact between the placement block 11 and the push block 10, ensuring the stability of continuous feeding. Several rollers 14 are rotatably provided on the inclined surface of the placement block 11. The rollers 14 can reduce the friction between the placement block 11 and the mounting block 13. The push block 10 is driven by an external driving component (such as a cylinder or electric push rod).

[0021] A first electric push rod 7 is fixedly mounted on the lathe body 1. The telescopic end of the first electric push rod 7 is provided with a second push assembly for pushing the workpiece on the first push assembly to the three-jaw chuck 2. The second push assembly includes a mounting frame 15 and a second electric push rod 16. The mounting frame 15 is fixed on the telescopic end of the first electric push rod 7, and the second electric push rod 16 is fixed on the mounting frame 15 and is used to push the workpiece on the placement block 11 to the three-jaw chuck 2. The telescopic end of the first electric push rod 7 drives the mounting frame 15 to move directly above the placement block 11, and the second electric push rod 16 extends to push the workpiece on the placement block 11 into the steering block 18 and push it to the three-jaw chuck 2.

[0022] A rotary cylinder 17 is fixed on the mounting bracket 15. A steering block 18 for placing workpieces is fixed on the rotating end of the rotary cylinder 17. A third electric push rod 19 is provided on the mounting bracket 15. The third electric push rod 19 is used to push the workpiece on the steering block 18 onto the three-jaw chuck 2. The three-jaw chuck 2 can push the workpiece that has been initially rough-machined into the steering block 18. The rotary cylinder 17 drives the steering block 18 to rotate 100°, so that the unmachined end of the workpiece faces the three-jaw chuck 2. Then the third electric push rod 19 pushes the workpiece in the steering block 18 into the clamping area of ​​the three-jaw chuck 2.

[0023] A guide frame 8 is slidably provided on one side of the lathe body 1 and is located below the three-jaw chuck 2. The cutting tool 5 is located between the guide frame 8 and the first pushing assembly. A hydraulic cylinder 20 is fixed on the lathe body 1 to push the guide frame 8 away from the lathe body 1. During machining, the guide frame 8 is located below the three-jaw chuck 2 and the cutting tool 5 moves freely between the guide frame 8 and the first pushing assembly. After machining is completed, the hydraulic cylinder 20 pushes the guide frame 8 to slide towards the lathe body 1 to directly below the workpiece. The three-jaw chuck 2 releases the workpiece and pushes it outward. The workpiece is automatically discharged along the inclined slide of the guide frame 8. The principle of the three-jaw chuck 2 pushing out the workpiece is that a hydraulic cylinder or pneumatic piston is designed behind the axis of the three-jaw chuck 2 to push the workpiece through the center hole at the axis of the three-jaw chuck 2.

[0024] Working principle:

[0025] The workpieces stacked in the storage bin 6 fall to the top of the push block 10 of the first push assembly under the action of gravity and fall onto the placement block 11. The push block 10 slides along the fixed frame 9 toward the lathe body 1. The placement block 11 rotates under the action of the spring 12, so that the axis of the workpiece coincides with the axis of the three-jaw chuck 2. When the push block 10 retracts, the inclined surface of the mounting block 13 contacts the placement block 11, forcing the placement block 11 to rotate around the pivot to a horizontal state. Then, the first electric push rod 7 drives the mounting frame 15 to move directly above the placement block 11, and the second electric push rod 16 extends to push the workpiece on the placement block 11 into the three-jaw chuck 2. The three-jaw chuck 2 clamps the workpiece.

[0026] Then the operator drives the three-jaw chuck 2 to rotate and the first slider 4 to move along the guide rail 3, driving the tool 5 to turn the clamped workpiece. When one end of the workpiece is turned, the first electric push rod 7 drives the mounting bracket 15 to move directly above the workpiece. The three-jaw chuck 2 pushes the workpiece onto the steering block 18. The rotary cylinder 17 drives the steering block 18 to rotate, so that the unprocessed end of the workpiece faces the three-jaw chuck 2. Then the operator starts the third electric push rod 19 to push the workpiece onto the three-jaw chuck 2 again.

[0027] After the workpiece is turned, the operator starts the hydraulic cylinder 20, which drives the guide frame 8 to move toward the lathe body 1. Then the three-jaw chuck 2 pushes the finished workpiece outward, and the workpiece falls onto the guide frame 8 and is discharged to the outside.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
