Description

Technical Field

[0001] This invention relates to the field of automatic loading and unloading devices, and more specifically, to an automatic loading and unloading device for a turning-milling composite CNC lathe robot. Background Technology

[0002] Composite machining is one of the most popular machining processes internationally in the field of mechanical processing. It is an advanced manufacturing technology. Composite machining combines several different machining processes on a single machine tool. The most widely used and most challenging composite machining process is mill-turn machining.

[0003] Most existing milling-turning CNC lathes rely on manual loading and unloading. This manual method increases labor intensity, increases the risk of workplace accidents, and is inefficient, failing to meet the demands of mass production. Therefore, we propose an automated loading and unloading robot for milling-turning CNC lathes. Summary of the Invention

[0007] As a preferred embodiment of the automatic loading and unloading device for a turning-milling composite CNC lathe robot of the present invention, the unloading assembly includes two symmetrically arranged unloading racks and side plates.

[0010] As a preferred embodiment of the automatic loading and unloading device for a CNC lathe robot of the present invention, the spring-loaded assembly includes two mounting brackets and connecting shafts.

The outer circumferential walls of the two connecting shafts are rotatably connected with rollers. The two rollers are located in the conveyor belt and roll in contact with its inner wall.

[0011] As a preferred embodiment of the automatic loading and unloading device for a turning-milling composite CNC lathe robot according to the present invention, the unloading assembly includes two connecting arms. Each connecting arm has a first connecting hole at its top and a second connecting hole on its outer wall. A slider is slidably connected to the inner wall of each of the first connecting holes.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In this invention, while unloading, a robotic arm can clamp the workpiece to be processed and insert it into the fixed chuck of a CNC lathe, thereby achieving automatic workpiece loading. Simultaneously, two dual-axis motors rotate synchronously in opposite directions, driving the connecting arms to rotate via the shaft plates at both ends. The connecting arms on the two unloading components tilt inward, allowing the ends of the connecting arms to clamp the workpiece. When the clamps contact the workpiece surface, the two clamps will drive the connecting plates to rotate along the extension shaft, thus securing the workpiece. Two first motors drive two rotating shafts located inside the housing to rotate synchronously in opposite directions, driving the conveyor rollers to rotate. The conveyor rollers drive the conveyor belt to rotate, and the multiple clamping teeth on the conveyor belt squeeze the workpiece surface, increasing the friction between the conveyor belt and the workpiece, thus clamping the workpiece between the two conveyor belts and simultaneously conveying it. The two conveyor belts transport the workpiece into the housing, thereby unloading the workpiece, reducing the labor intensity of workers, lowering the rate of workplace accidents, and improving workpiece processing efficiency.

[0017] 2. In this invention, the cross slide can drive the box to move horizontally and vertically, and the hydraulic cylinder can drive the bracket to slide along the inner wall of the second mounting hole, thereby adjusting the height of the feeding component and the unloading component, and the box can drive the feeding component and the unloading component to move.

[0018] 3. In this invention, when multiple clamping teeth contact the cylindrical workpiece, the first and second rubber pads on the outer wall of the tooth base can elastically contact the surface of the cylindrical workpiece, thereby increasing the friction between the tooth and the cylindrical workpiece and reducing the wear on the surface of the cylindrical workpiece. By setting a buffer pad between the first and second rubber pads, the tooth arm and tooth cap can effectively release pressure to the outside when subjected to the reverse extrusion force of the cylindrical workpiece. By installing the first rubber pads that protrude outward on both sides of the tooth cap, the protrusions on both sides of the tooth cap can effectively provide support for the workpiece and increase the extrusion force between the first rubber pad and the cylindrical workpiece.

[0019] 4. In this invention, the toothed cap is fixed to the toothed seat by the nut and screw, so that the toothed cap can be disassembled and replaced. By setting the toothed groove on the top of the toothed cap, the two sides of the toothed cap can bulge outward, so that the two sides of the toothed cap can provide effective support.

[0020] 5. In this invention, during the conveying operation, the two conveyor belts can drive the rollers on multiple spring-loaded components to roll. The two rollers on the multiple spring-loaded components can limit the distance between the conveyor belts. Under the elastic force of the first spring, the two rollers can squeeze the two conveyor belts inward, preventing the two conveyor belts from becoming loose under the elastic force, which would result in insufficient clamping force between the two conveyor belts and the workpiece, causing them to loosen.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Example 1:

[0038] like Figure 1 , Figure 2 and Figure 13 As shown, an automatic loading and unloading device for a CNC lathe robot with milling and turning capabilities includes an adjustment component 1, a loading component 2 mounted on the housing of the adjustment component 1, multiple spring-loaded components 3 mounted on both sides of the loading component 2, and two unloading components 4 mounted at the end of the loading component 2.

[0039] Example 2:

[0040] like Figure 3 and Figure 4 As shown, this embodiment is based on the previous embodiment, but differs from the previous embodiment in that: the adjustment component 1 includes a cross slide 101, a mounting platform 102 is fixedly connected to the end of the cross slide 101, a robot arm 103 is fixedly connected to the top of the mounting platform 102, the robot arm 103 is used to clamp the workpiece and transport it into the chuck hole, a housing 104 is fixedly connected to the top of the sliding part of the cross slide 101, a first mounting hole 105 is opened on the outer wall of the housing 104, a second mounting hole 106 is opened on both sides of the housing 104, a discharge hole 107 is opened on the outer wall of the housing 104, a hydraulic cylinder 108 is fixedly connected to the bottom of the inner wall of the housing 104, a bracket 109 is fixedly connected to the top of the output end of the hydraulic cylinder 108, the two ends of the bracket 109 are slidably connected to the inner walls of the two second mounting holes 106 respectively, and a first motor 110 is fixedly connected to both sides of the bracket 109.

[0041] The cross slide 101 can drive the box 104 to move horizontally and vertically, and the hydraulic cylinder 108 can drive the bracket 109 to slide along the inner wall of the second mounting hole 106, thereby adjusting the height of the unloading assembly 2 and the unloading assembly 4, and the box 104 can drive the unloading assembly 2 and the unloading assembly 4 to move.

[0042] Example 3:

[0043] like Figures 5-10As shown, this embodiment is based on the previous embodiment, but differs in that: the feeding assembly 2 includes two symmetrically arranged feeding racks 201 and side plates 206. The ends of both feeding racks 201 pass through the first mounting hole 105 and extend into the housing 104. The outer walls of the two side plates 206 are respectively connected and fixed to the inner wall of the bracket 109. The two side plates 206 are respectively connected and fixed to the two feeding racks 201. The inner walls at both ends of the two feeding racks 201 are rotatably connected to rotating shafts 202. The outer walls of the multiple rotating shafts 202 are fixedly connected to conveying rollers 203. The outer walls of the two conveying rollers 203 located inside the same feeding rack 201 are fitted with conveyor belts 204. The outer walls of the two conveyor belts 204 are fixedly connected to multiple clamping teeth 205. The ends of the rotating shafts 202 are respectively connected and fixed to the first motors 110; the two first motors 110 drive the two rotating shafts 202 located inside the housing 104 to rotate synchronously in opposite directions, and the two rotating shafts 202 drive the conveyor rollers 203 to rotate, and the conveyor rollers 203 can drive the conveyor belt 204 to rotate. The multiple clamping teeth 205 on the conveyor belt 204 squeeze the surface of the workpiece, increasing the friction between the conveyor belt 204 and the workpiece, so that the workpiece can be clamped between the two conveyor belts 204 and simultaneously clamped and conveyed. The two conveyor belts 204 can transport the workpiece into the housing 104, thereby unloading the workpiece. The unloading hole 107 on the housing 104 makes it easy for the operator to pick up the workpiece.

[0044] The clamping tooth 205 includes a tooth base 2051, tooth arms 2052 fixedly connected to both inclined surfaces of the tooth base 2051, tooth arms 2052 having a triangular structure, a tooth cap 2053 fixedly connected to the top of the tooth base 2051, the tooth cap 2053 having triangular pointed structures on both sides, a tooth groove 2054 opened on the top of the tooth cap 2053, a first rubber pad 2055 fixedly connected to both inclined surfaces of the tooth cap 2053, a second rubber pad 2056 fixedly connected to the outer wall of both tooth arms 2052, and a buffer pad 2057 fixedly connected to both edges of the top of the tooth base 2051. The tooth arms 2052 and the tooth cap 2053 are both metal plates, the first rubber pad 2055 and the second rubber pad 2056 are both rubber pads, and the outer walls of the first rubber pad 2055, the second rubber pad 2056 and the buffer pad 2057 are connected to form a curved surface structure with bent ends.

[0045] The gear base 2051 has multiple threaded holes 2062 evenly spaced on its top, and the gear cap 2053 has multiple through holes 2063 evenly spaced on its top. Multiple screws 2059 are threaded through the inner walls of each through hole 2063, and the tops of each screw 2059 are threaded into the threaded holes 2062. Nuts 2058 are fixedly connected to the tops of each screw 2059, and each nut 2058 has a butt joint arc 2060 on its top. A cross groove 2061 is formed on the inner wall of each gear groove 2054, and the butt joint arc 2060 connects with the gear groove 2054 to form an arc surface structure. When the multiple clamping teeth 205 are in contact with the cylindrical workpiece, the gear base 205... The first rubber pad 2055 and the second rubber pad 2056 on the outer wall can elastically contact the surface of the cylindrical workpiece, thereby increasing the friction between them and the cylindrical workpiece, while reducing the wear on the surface of the cylindrical workpiece. By setting a buffer pad 2057 between the first rubber pad 2055 and the second rubber pad 2056, the tooth arm 2052 and the tooth cap 2053 can effectively release pressure to the outside when subjected to the reverse extrusion force of the cylindrical workpiece. By installing the outwardly protruding first rubber pad 2055 on both sides of the tooth cap 2053, the protrusions on both sides of the tooth cap 2053 can effectively support the workpiece and increase the extrusion force between the first rubber pad 2055 and the cylindrical workpiece.

[0046] By fixing the toothed cap 2053 to the toothed seat 2051 with the nut 2058 and the screw 2059, the toothed cap 2053 can be disassembled and replaced. By providing the toothed groove 2054 on the top of the toothed cap 2053, the two sides of the toothed cap 2053 can protrude outward, so that the two sides of the toothed cap 2053 can provide effective support.

[0047] Example 4:

[0048] like Figure 11 As shown, this embodiment is based on the previous embodiment, but differs from the previous embodiment in that: the spring-loaded assembly 3 includes two mounting brackets 301 and a connecting shaft 306. The two mounting brackets 301 are respectively connected and fixed to the side walls of the two unloading racks 201. The outer walls of the two mounting brackets 301 are provided with fixing holes 302. The inner walls of the two fixing holes 302 are fixedly connected with fixing rods 303. The outer circumference of the two fixing rods 303 is fitted with a first spring 304. The outer circumference of the two fixing rods 303 is slidably fitted with two limiting sleeves 305. The two ends of the two connecting shafts 306 extend into the interior of the fixing holes 302. The ends of the two fixing rods 303 pass through the connecting shafts 306 and are slidably connected to them. The outer circumference of the two connecting shafts 306 is rotatably connected with rollers 307. The two rollers 307 are located inside the conveyor belt 204 and roll in contact with its inner wall. The two ends of the first springs 304 are respectively connected and fixed to the limiting sleeves 305. The ends of the multiple limiting sleeves 305 abut against the outer wall of the connecting shafts 306.

[0049] During the conveying process, the two conveyor belts 204 can drive the rollers 307 on the multiple spring-loaded components 3 to roll. The two rollers 307 on the multiple spring-loaded components 3 can limit the distance between the conveyor belts 204. Under the elastic force of the first spring 304, the two rollers 307 can squeeze the two conveyor belts 204 inward, so as to prevent the two conveyor belts 204 from becoming loose under the elastic force, which would result in insufficient clamping force of the two conveyor belts 204 on the workpiece and loosening.

[0050] Example 5:

[0051] like Figure 12 As shown, this embodiment is based on the previous embodiment, but differs from the previous embodiment in that: the unloading assembly 4 includes two connecting arms 401, each of the two connecting arms 401 has a first connecting hole 402 at its top, and each of the two connecting arms 401 has a second connecting hole 403 on its outer wall. Each of the two first connecting holes 402 has a slider 407 slidably connected to its inner wall. The ends of the two sliders 407 pass through the second connecting holes 403 and extend to their outer sides. Each of the two connecting arms 401 has a fixing block 404 fixedly connected to its outer side. Each of the two fixing blocks 404 has a sliding rod 405 fixedly connected to its end. The ends of the two sliding rods 405 pass through the sliders 407 and are slidably connected to them. Each of the two sliding rods 405 has a second spring 406 sleeved on its outer circumference. One end of the second spring 406 is fixedly connected to the fixing block 404, and the other end of the second spring 406 is fixedly connected to the slider 407.

[0052] The unloading assembly 4 also includes a dual-axis motor 410, which is connected and fixed to the unloading frame 201. The top of each of the two sliders 407 is fixedly connected to a shaft plate 408, and the inner wall of each of the two shaft plates 408 is fixedly connected to a fixed shaft 409. The two output ends of the dual-axis motor 410 are respectively connected and fixed to the fixed shaft 409. The ends of each of the two connecting arms 401 are fixedly connected to an extension shaft 411 through a through-type connection. The outer circumference of each of the two extension shafts 411 is rotatably connected to two connecting plates 413. The ends of the two connecting plates 413 on the same extension shaft 411 are fixedly connected to clamps 414. Each end of the two extension shafts 411 is fitted with a torsion spring 412. One end of the torsion spring 412 is fixedly connected to the extension shaft 411, and the other end of the torsion spring 412 is fixedly connected to the connecting plate 413.

[0053] Two dual-axis motors 410 rotate synchronously in opposite directions, driving the connecting arms 401 to rotate through the shaft plates 408 at both ends. The connecting arms 401 on the two unloading assemblies 4 tilt inward, so that the ends of the connecting arms 401 can clamp the workpiece. When the clamp 414 contacts the surface of the workpiece, the two clamps 414 will drive the connecting plate 413 to rotate along the extension shaft 411, thereby enabling the workpiece to be firmly clamped.

[0054] After the workpiece is clamped, the unloading assembly 4 is driven by the cross slide 101 to move the workpiece out from inside the turning and milling CNC lathe. The two dual-axis motors 410 continue to drive the connecting arm 401 to squeeze the workpiece inward. At this time, the slider 407 will slide along the inner wall of the first connecting hole 402 and the second connecting hole 403. At the same time, the slider 407 will slide along the slide rod 405 towards the end close to the fixed block 404, so that the slider 407 squeezes the second spring 406 until the connecting arm 401 on the upper and lower unloading assemblies 4 is perpendicular to the unloading frame 201. At this time, the workpiece contacts the ends of the two conveyor belts 204.

[0055] Working principle: The cross slide 101 can drive the box 104 to move horizontally and vertically, and the hydraulic cylinder 108 can drive the bracket 109 to slide along the inner wall of the second mounting hole 106, which can adjust the height of the feeding assembly 2 and the unloading assembly 4. The box 104 drives the feeding assembly 2 and the unloading assembly 4 to move.

[0056] Two dual-axis motors 410 rotate synchronously in opposite directions, driving the connecting arms 401 to rotate through the shaft plates 408 at both ends. The connecting arms 401 on the two unloading assemblies 4 tilt inward, so that the ends of the connecting arms 401 can clamp the workpiece. When the clamp 414 contacts the surface of the workpiece, the two clamps 414 will drive the connecting plate 413 to rotate along the extension shaft 411, which can firmly clamp the workpiece.

[0057] After the workpiece is clamped, the unloading assembly 4 is driven by the cross slide 101 to move the workpiece out from inside the turning and milling CNC lathe. The two dual-axis motors 410 continue to drive the connecting arm 401 to squeeze the workpiece inward. At this time, the slider 407 will slide along the inner wall of the first connecting hole 402 and the second connecting hole 403. At the same time, the slider 407 will slide along the slide rod 405 towards the end close to the fixed block 404, so that the slider 407 squeezes the second spring 406 until the connecting arm 401 on the upper and lower unloading assemblies 4 is perpendicular to the unloading frame 201. At this time, the workpiece contacts the ends of the two conveyor belts 204.

[0058] Two first motors 110 drive two rotating shafts 202 located inside the housing 104 to rotate synchronously in opposite directions. The two rotating shafts 202 drive the conveyor rollers 203 to rotate. The conveyor rollers 203 can drive the conveyor belt 204 to rotate. The multiple clamping teeth 205 on the conveyor belt 204 squeeze the surface of the workpiece, increasing the friction between the conveyor belt 204 and the workpiece. The workpiece can be clamped between the two conveyor belts 204 and simultaneously clamped and conveyed. The two conveyor belts 204 can transport the workpiece into the housing 104 for unloading. The unloading hole 107 on the housing 104 makes it easy for the operator to pick up the workpiece.

[0059] During the conveying operation, the two conveyor belts 204 can drive the rollers 307 on the multiple spring-loaded components 3 to roll. The two rollers 307 on the multiple spring-loaded components 3 can limit the distance between the conveyor belts 204. Under the elastic force of the first spring 304, the two rollers 307 can squeeze the two conveyor belts 204 inward to prevent the two conveyor belts 204 from becoming loose under the elastic force, which would result in insufficient clamping force of the two conveyor belts 204 on the workpiece and cause loosening.

[0060] While unloading, the robot arm 103 can clamp the workpiece to be processed and insert it into the fixed chuck of the turning and milling composite CNC lathe, thus realizing automatic loading of the workpiece.

[0061] When multiple clamping teeth 205 are in contact with a cylindrical workpiece, the first rubber pad 2055 and the second rubber pad 2056 on the outer wall of the tooth base 2051 can elastically contact the surface of the cylindrical workpiece, thereby increasing the friction between the tooth and the cylindrical workpiece and reducing the wear on the surface of the cylindrical workpiece. By setting a buffer pad 2057 between the first rubber pad 2055 and the second rubber pad 2056, the tooth arm 2052 and the tooth cap 2053 can effectively release pressure to the outside when subjected to the reverse extrusion force of the cylindrical workpiece. By installing the outwardly protruding first rubber pad 2055 on both sides of the tooth cap 2053, the protrusions on both sides of the tooth cap 2053 can effectively support the workpiece and increase the extrusion force between the first rubber pad 2055 and the cylindrical workpiece.

[0062] By fixing the toothed cap 2053 to the toothed seat 2051 with the nut 2058 and the screw 2059, the toothed cap 2053 can be disassembled and replaced. By providing the toothed groove 2054 on the top of the toothed cap 2053, the two sides of the toothed cap 2053 can protrude outward, so that the two sides of the toothed cap 2053 can provide effective support.
