Description

Technical Field

[0001] This utility model relates to the technical field of automatic loading and unloading devices, specifically an automatic loading and unloading device for turning spherical washers. Background Technology

[0002] Spherical washers are a special type of washer in mechanical connections. They achieve adaptive angle adjustment through spherical mating, solving connection problems caused by installation deviations and component deformation in mechanical assembly. They are key auxiliary parts in high-precision and high-reliability assembly. Spherical washers are mainly machined by cutting, and in order to improve production efficiency, it is necessary to ensure the continuity of material supply.

[0003] Currently, the loading and unloading of spherical washers in turning mainly relies on robotic arms. The robotic arm clamps the workpiece and feeds it into the clamping part of the machine tool. After machining, the robotic arm removes the machined part and loads it back in. However, the existing loading and unloading devices have high maintenance costs and are expensive to manufacture, making them unsuitable for widespread application in small production lines. This increases production costs and hinders widespread adoption. Therefore, to address these issues, an automatic loading and unloading device for turning spherical washers is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, which result in high usage and maintenance costs, leading to increased production costs and hindering widespread application, this utility model proposes an automatic loading and unloading device for turning spherical washers.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: An automatic loading and unloading device for turning spherical washers, comprising a machine tool body, a clamping part and a sliding tool table provided on the side wall of the machine tool body, a hydraulic rod supported and fixed on the sliding surface of the sliding tool table by a support frame, and the actuating end of the hydraulic rod facing the clamping part and fixedly connected to an electromagnet, a material drop hopper inclinedly fixed on the sliding surface of the sliding tool table, and the higher inclined end of the material drop hopper located below the extension end of the hydraulic rod, and a tool holder fixed on the sliding tool table.

[0006] The machine tool body is provided with a clamping part on the side wall, and a material storage component and a material distribution component are provided. The material distribution component is slidably disposed below the material dropping end of the material storage component. The material distribution component can slide between the clamping part and the electromagnet.

[0007] A base plate is slidably disposed inside the material distribution component. Multiple connecting plates are fixedly connected to the base plate. A top plate is fixedly connected to the top of the multiple connecting plates. A material discharge groove is provided on the top plate. The top plate is slidably attached to the lower part of the material discharge end of the material storage component and the material discharge groove is directly opposite the material discharge port of the material storage component. Two second wedges for blocking material are provided inside the opening of the material discharge groove.

[0008] Preferably, the material storage assembly includes a feed pipe fixed to the side wall of the machine tool body, and the top plate is slidably attached to the bottom opening of the feed pipe, and a material storage hopper is fixedly connected to the top of the feed pipe.

[0009] Preferably, the material distribution assembly includes two fixed frames fixed to the side wall of the machine tool body, a second limiting rod fixed between the two fixed frames, two second connecting seats slidably arranged on the two second limiting rods, and the base plate is fixedly connected to the two second connecting seats.

[0010] Preferably, a one-way lead screw is rotatably installed between the two fixed frames, and the one-way lead screw passes through and is threadedly connected to the sides of the two No. 2 connecting seats. One end of the rotation center shaft of the one-way lead screw is connected to a motor, and the motor is fixed on the corresponding fixed frame.

[0011] Preferably, a guide rail is fixedly connected to the base plate, and the two second wedges are slidably disposed on the two guide rails. A second bidirectional lead screw is rotatably installed between the two connecting plates, and the second bidirectional lead screw passes through and is threadedly connected to the side of the two second wedges. One end of the rotation center axis of the second bidirectional lead screw is fixedly connected to a second turntable.

[0012] Preferably, the bottom end of the feed pipe has openings on two side walls opposite to its opening, and guide grooves are provided on the inner walls adjacent to the openings of the feed pipe. A wedge is slidably disposed in the openings on both sides of the bottom end of the feed pipe, and guide strips are provided on the side walls of the two wedges to slide and engage with the guide grooves.

[0013] Preferably, a connecting seat is fixedly connected to each of the two wedge blocks, and a bidirectional screw is threadedly connected between the two connecting seats. The middle section of the bidirectional screw is rotatably mounted on the outer wall of the feed pipe through an adapter. The two connecting seats are symmetrically distributed at both ends of the bidirectional screw, and a turntable is fixedly connected to the end of the bidirectional screw.

[0014] Preferably, a fixing plate is fixed to the upper edge of the opening where the two wedges slide into contact. Each fixing plate has a groove, and an L-shaped baffle is slidably disposed within the groove. The vertical section of the L-shaped baffle is slidably disposed within the groove of the fixing plate.

The bottom end of the L-shaped baffle slidably abuts against the inclined surface of the wedge.

[0015] The advantages of this utility model are:

[0016] 1. This utility model uses two No. 2 connecting seats to drive the base plate to move horizontally, which in turn drives the top plate to slide at the bottom of the feed pipe. The workpiece inside the feed pipe will leak into the discharge chute. The top plate will then block the leakage port at the bottom of the feed pipe again. The electromagnet, under the pushing of the hydraulic rod, will push the workpiece located between the two No. 2 wedges into the clamping part for fixation. After the cutting is completed, the hydraulic rod will move horizontally again to face the clamping part. The workpiece will be attracted to the electromagnet, thus completing the material removal. When the electromagnet drives the workpiece to retract to the higher end of the discharge hopper, the electromagnet will be de-energized, causing it to lose its magnetism, and the workpiece attracted to it will fall onto the discharge hopper for unloading.

[0017] 2. When the No. 1 bidirectional lead screw rotates, it drives the two No. 1 connecting seats to simultaneously slide the two No. 1 wedges in opposite directions within the opening at the bottom of the feed tube. This causes the distance between the two No. 1 wedges to shrink or expand, making it suitable for uniform feeding of workpieces of different diameters. Only one workpiece can pass through at a time. Furthermore, by rotating the No. 2 turntable, the two No. 2 wedges slide in opposite directions on the guide rail, causing the distance between the two No. 2 wedges to shrink or expand, ensuring that only one workpiece can be stored in the feeding trough at a time, thus guaranteeing the feeding effect.

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 scope of protection of the present utility model.

[0028] Please see Figure 1-5 As shown, an automatic loading and unloading device for turning spherical washers includes a machine tool body 1. A clamping part 12 and a sliding tool table 11 are provided on the side wall of the machine tool body 1. A hydraulic rod 13 is supported and fixed on the sliding surface of the sliding tool table 11 by a support frame 16. The actuating end of the hydraulic rod 13 faces the clamping part 12 and is fixedly connected to an electromagnet 17. A discharge hopper 15 is inclinedly fixed on the sliding surface of the sliding tool table 11, and the higher inclined end of the discharge hopper 15 is located below the extension end of the hydraulic rod 13. A tool holder 14 is fixed on the sliding tool table 11.

[0029] The machine tool body 1 is provided with a clamping part 12 on its side wall, and a material storage component 2 and a material distribution component 3 are provided. The material distribution component 3 is slidably disposed below the material dropping end of the material storage component 2. The material distribution component 3 can slide between the clamping part 12 and the electromagnet 17.

[0030] A base plate 36 is slidably disposed inside the material distribution component 3. Multiple connecting plates 37 are fixedly connected to the base plate 36. A top plate 38 is fixedly connected to the top of the multiple connecting plates 37. A material discharge groove 39 is provided on the top plate 38. The top plate 38 is slidably attached to the lower part of the material discharge end of the material storage component 2 and the material discharge groove 39 is directly opposite the material discharge port of the material storage component 2. Two second wedges 311 for blocking material are provided inside the opening of the material discharge groove 39.

[0031] The material storage assembly 2 includes a feed pipe 21 fixed on the side wall of the machine tool body 1, and the top plate 38 is slidably attached to the bottom opening of the feed pipe 21. A storage hopper 22 is fixedly connected to the top of the feed pipe 21.

[0032] The material distribution assembly 3 includes two fixed frames 31 fixed to the side wall of the machine tool body 1. A second limiting rod 32 is fixed between the two fixed frames 31. Two second connecting seats 33 are slidably arranged on the two second limiting rods 32, and the base plate 36 is fixedly connected to the two second connecting seats 33.

[0033] A one-way screw 34 is rotatably mounted between the two fixed brackets 31, and the one-way screw 34 passes through and is threadedly connected to the sides of the two second connecting seats 33. One end of the rotation center shaft of the one-way screw 34 is connected to a motor 35, and the motor 35 is fixed on the corresponding fixed bracket 31.

[0034] A guide rail 310 is fixedly connected to the base plate 36, and the two second wedge blocks 311 are slidably disposed on the two guide rails 310. A second bidirectional lead screw 312 is rotatably installed between the two connecting plates 37, and the second bidirectional lead screw 312 passes through and is threadedly connected to the side of the two second wedge blocks 311. One end of the rotation center axis of the second bidirectional lead screw 312 is fixedly connected to a second turntable 313.

[0035] The bottom end of the feed pipe 21 has openings on two side walls opposite to its opening. Guide grooves 24 are provided on the inner walls adjacent to the openings of the feed pipe 21. A wedge 23 is slidably arranged in the openings on both sides of the bottom end of the feed pipe 21, and guide strips 25 are provided on the side walls of the two wedges 23 to slide and fit into the guide grooves 24.

[0036] Each of the two wedge blocks 23 is fixedly connected to a connecting seat 212. The two connecting seats 212 are connected together by a threaded double-acting screw 213. The middle section of the double-acting screw 213 is rotatably mounted on the outer wall of the feed pipe 21 via an adapter 211. The two connecting seats 212 are symmetrically distributed at both ends of the double-acting screw 213. A turntable 214 is fixedly connected to the end of the double-acting screw 213.

[0037] A first fixing plate 26 is fixed to the upper edge of the opening where the two first wedges 23 slide into contact. Each first fixing plate 26 has a groove, and an L-shaped baffle 27 is slidably disposed in the groove. The vertical section of the L-shaped baffle 27 is slidably disposed in the groove of the first fixing plate 26. A second fixing plate 28 is fixed to the outer wall of the feed pipe 21 above the first fixing plate 26. A first limiting rod 29 is fixed between the second fixing plate 28 and the first fixing plate 26. The horizontal section of the L-shaped baffle 27 is slidably disposed on the first limiting rod 29. A spring 210 is sleeved on the first limiting rod 29. The spring 210 is located between the second fixing plate 28 and the horizontal section of the L-shaped baffle 27. The bottom end of the L-shaped baffle 27 slides against the inclined surface of the first wedge 23.

[0038] During operation, the existing loading and unloading devices have high maintenance costs and high manufacturing costs, making them unsuitable for widespread application in small production lines, which increases production costs and hinders widespread application. In this solution, under the initial turntable, the spring 210 will always push the horizontal section of the L-shaped baffle 27 downwards, so that the vertical section of the L-shaped baffle 27 extends downwards and abuts against the inclined surface of the first wedge block 23, thereby preventing parts from leaking out from between the bottom opening of the feed pipe 21 and the first wedge block 23, ensuring normal material supply.

[0039] In use, the workpiece is placed into the storage hopper 22 and the feed pipe 21. With the top plate 38 sealing the bottom of the feed pipe 21, the workpiece remains within the feed pipe 21 and the storage hopper 22. The thickness of the feed pipe 21 and the storage hopper 22 is slightly greater than the thickness of the workpiece, ensuring that the end faces of the workpiece slide against the inner wall. Then, the motor 35 is controlled to operate. When the motor 35 operates, it drives the one-way lead screw 34 to rotate. As the one-way lead screw 34 rotates, it is limited by the second limit rod 32 on the second connecting seat 33. The bottom plate 36 is moved horizontally by the two No. 2 connecting seats 33, which in turn causes the top plate 38 to slide at the bottom end of the feed pipe 21. When the discharge chute 39 slides directly opposite the discharge port at the bottom end of the feed pipe 21, the workpiece inside the feed pipe 21 will fall into the discharge chute 39 and be positioned between the two No. 1 wedges 23. The distance between the two No. 1 wedges 23 can only hold a single workpiece. Then, the motor 35 drives in the reverse direction to cause the top plate 38 to block the discharge port at the bottom end of the feed pipe 21 again, and the discharge chute 39 will move horizontally. For the clamping part 12, the hydraulic rod 13 is then extended so that the electromagnet 17, under the pushing force of the hydraulic rod 13, pushes the workpiece located between the two second wedges 311 into the clamping part 12 for fixing, thus completing the loading. Then, the motor 35 drives the material to be picked up again using the material drop chute 39, and at this time, the top plate 38 will move away from the clamping part 12. Then, the workpiece can be turned by the tool holder 14 on the sliding tool table 11 under the translation, thus completing the workpiece machining. After the turning is completed, the hydraulic rod 13 is then... The workpiece is then moved to face the clamping part 12 and then energized to the electromagnet 17, causing its inner coil to generate magnetism. At this time, after the electromagnet 17 comes into contact with the machined workpiece and the clamping part 12 releases the clamp, the workpiece will be attracted to the electromagnet 17, thus completing the material handling. When the electromagnet 17 drives the workpiece back to the higher end of the dropping hopper 15, the electromagnet 17 is de-energized, causing it to lose its magnetism, and the workpiece attracted to it falls onto the dropping hopper 15 for unloading, thus completing the automatic loading and unloading of the machined workpiece.

[0040] Rotating the first turntable 214 drives the first bidirectional lead screw 213 to rotate. When the first bidirectional lead screw 213 rotates, it drives the two first wedges 23 to slide in opposite directions in the opening at the bottom of the feed pipe 21 through the two first connecting seats 212. This causes the distance between the two first wedges 23 to shrink or expand, so as to uniformly feed workpieces of different diameters. Only one workpiece can pass through at a time. Rotating the second turntable 313 drives the two second wedges 311 to slide in opposite directions on the guide rail 310, so that the distance between the two second wedges 311 shrinks or expands, so that only one workpiece can be stored in the dropping trough 39 at a time, to ensure the feeding effect and avoid feeding too many workpieces at a time, which would affect the normal feeding process.

[0041] It achieves automatic loading and unloading, and has lower usage and maintenance costs compared to traditional robotic arm loading and unloading structures, effectively reducing operating costs and facilitating widespread application.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
