[0002] Copper processing is one of the more common processing materials in the field of metal materials processing. Among them, copper rods are one of the most common copper materials. In the production and processing of copper rods, they need to be processed to make them to a specific diameter for subsequent use.

[0003] The existing copper rod processing is mostly carried out by turning on a lathe. Specifically, the operator holds the copper rod while operating the fixture to clamp the two ends of the copper rod and controls the copper rod to rotate at high speed by the lathe. Then, the lathe controls the cutting tool to pass through the outer surface of the copper rod to turn off the excess part to complete the processing. After processing, the operator holds the copper rod while operating the fixture to release the two ends of the copper rod for unloading.

[0020] To enable those skilled in the art to better understand the present invention and to more clearly define the scope of protection of the present invention, the present invention will be described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present invention, and are merely a part of the embodiments of the present invention. The specific and direct descriptions of related structures are only for the convenience of understanding the present invention, and the specific features do not necessarily or directly limit the scope of the present invention. Conventional choices and substitutions made by those skilled in the art under the guidance of the present invention should be considered within the scope of protection of the present invention.

[0021] like Figures 1-2 As shown, this invention discloses an automatic clamping and unloading copper rod polishing device, comprising: The frame 1 has a motor mounting area 11 on the upper rear side and a conveying and grinding area 12 on the upper front side. The conveying and grinding area 12 includes, from left to right, a loading station 121, a diameter screening station 122, a length screening station 123, a positioning station 124, a grinding station 125, and a unloading station 126. Conveying mechanism 2 is mounted on frame 1; Tooling fixture 3 is set on the conveying mechanism 2 to convey material sequentially through the loading station 121, diameter screening station 122, length screening station 123, positioning station 124, grinding station 125 and unloading station 126. Grinding mechanism 4 is located at grinding station 125.

[0022] Therefore, the copper rod 9 to be ground is loaded into the tooling fixture 3 at the loading station 121, and then conveyed by the conveying mechanism 2 to the diameter screening station 122. If the diameter of the copper rod 9 is suitable, the conveying continues; if the diameter of the copper rod 9 is insufficient, the copper rod 9 is unloaded and no further conveying is carried out. Then it goes to the length screening station 123. If the length of the copper rod 9 is suitable, the conveying continues; if the length of the copper rod 9 is insufficient, the copper rod 9 is unloaded and no further conveying is carried out. Then the copper rod 9 with the suitable diameter and length is conveyed to the positioning station 124 for adjustment and clamping, and then conveyed to the grinding station 125 to grind the copper rod 9 to the appropriate diameter. Finally, the copper rod 9 is unloaded at the unloading station 126. The whole process only requires manual or robotic arm to put the copper rod 9 to be processed into the loading station 121, which makes the processing more convenient and improves the processing efficiency.

[0023] Specifically, such as Figure 3 As shown, the conveying mechanism 2 includes a conveying assembly 21 and two conveying chains 22. The conveying assembly 21 includes a third motor 211, a drive shaft 212, a driven shaft 213, and multiple sprockets 214. The third motor 211 is fixedly installed on the left side of the motor mounting area 11. The drive shaft 212 and the driven shaft 213 are rotatably mounted on the left and right sides of the conveying and grinding area 12 using bearings. The axes of the drive shaft 212 and the driven shaft 213 are along the front-to-back direction. Each drive shaft 212 and the driven shaft 213 is equipped with sprockets 214 spaced at a front-to-back distance. The other sprockets 214 are rotatably mounted in the conveying and grinding area 12 using shafts, bearings, etc. Each conveyor chain 22 is arranged in a ring and connected to each sprocket 214. The third motor 211 and the drive shaft 212 are connected by a synchronous belt and synchronous pulley so that the operation of the third motor 211 can drive the conveyor chain 22 to achieve the conveying work. The front and rear ends of the fixture body 31 are fixedly installed to different units of the conveyor chain 22 by bolts and nuts, so that the conveyor chain 22 can drive the fixture body 31 to circulate through the loading station 121, diameter screening station 122, length screening station 123, positioning station 124, grinding station 125 and unloading station 126 in sequence.

[0024] Among them, such as Figures 5-8As shown, the tooling fixture 3 includes a fixture body 31, a first chuck assembly 32, and a second chuck assembly 33. The fixture body 31 is provided with a clamping area 311, the length direction of which is along the front-to-back direction. The clamping area 311 has a loading opening 3111 and a unloading opening 3112 on both sides of its depth. The width of the loading opening 3111 is d1, and the width of the unloading opening 3112 is d2, wherein d1 > d2. The first chuck assembly 32 and the second chuck assembly 33 are both slidably disposed on the fixture body 31, and the first chuck assembly 32 and the second chuck assembly 33 are located at the front and rear ends of the clamping area 311. The first chuck assembly 32 is provided with a first guide portion 323, and the second chuck assembly 33 is provided with a second guide portion 333.

[0025] Specifically, the first chuck assembly 32 includes a first sliding seat 321 and a first rotating chuck 322. The first sliding seat 321 is slidably mounted on the fixture body 31 in the front-back direction using a guide rail and a slider. The first rotating chuck 322 is rotatably mounted on the first sliding seat 321 using a ball bearing and / or a push bearing.

[0026] Similarly, the second chuck assembly 33 includes a second sliding seat 331 and a second rotating chuck 332. The second sliding seat 331 is slidably mounted on the fixture body 31 in the front-back direction using a guide rail and a slider. The second rotating chuck 332 is rotatably mounted on the second sliding seat 331 using a ball bearing and / or a pressure bearing.

[0027] The first rotating chuck 322 is coaxial with the rotation axis of the first sliding seat 321 and the second rotating chuck 332 is coaxial with the rotation axis of the second sliding seat 331, and both are in the front-back direction.

[0028] The clamp body 31 has a first support portion 312 and a second support portion 313 on both sides of the width of the clamping area 311. The first support portions 312 on both sides are symmetrically arranged with respect to the rotation axis of the first rotating chuck 322 relative to the rotation axis of the first sliding seat 321. The second support portions 313 on both sides are symmetrically arranged with respect to the rotation axis of the first rotating chuck 322 relative to the rotation axis of the first sliding seat 321. The first support portions 312 and the second support portions 313 are slidably disposed on the clamp body 31 along the depth direction of the clamping area 311. A space is provided between the clamp body 31 and the first support portions 312. A first spring 314 is provided to reset the first support part 312 in a direction away from the feeding opening 3111. A second spring 315 is provided between the first support part 312 and the second support part 313 to reset the second support part 313 in a direction close to the feeding opening 3111. Each first support part 312 is provided with a first support position 3121, and each second support part 313 is provided with a second support position 3131. The distance between two first support positions 3121 is d3, and the distance between two second support positions 3131 is d4, where d2=d3=d4.

[0029] Specifically, the fixture body 31 is provided with multiple mounting screw holes 316 of different depths, and the opening orientation of the mounting screw holes 316 is opposite to that of the loading opening 3111. In addition, it also includes mounting bolts 317. The first support part 312 is provided with mounting through holes 3122 that extend along the depth direction of the clamping area 311. The mounting bolts 317 pass through the mounting through holes 3122 and are threaded to the deepest part of any mounting screw hole 316. In addition, the first spring 314 is sleeved on the outer periphery of the mounting bolt 317, and under the reset action of the first spring 314, the first support part 312 abuts against the head of the mounting bolt 317, so that the first support part 312 and the fixture body 31 are fixedly set.

[0030] Specifically, by fitting the mounting bolts 317 into different mounting screw holes 316, the distance between the planes where the two first support positions 3121 are located and the rotation axis of the first rotating chuck 322 relative to the first sliding seat 321 can be adjusted.

[0031] The clamp body 31 has a first through hole 318 extending through the depth of the clamping area 311, the second support 313 has a second through hole 3132 extending through the depth of the clamping area 311, and the first support 312 has a third threaded hole 3123 extending through the depth of the clamping area 311. This allows bolts to pass through the first through hole 318 and the second through hole 3132 in sequence and be threaded into the third threaded hole 3123 to guide the sliding of the second support 313. In addition, a second spring 315 is sleeved on the outer periphery of the bolt, and the second support 313 is reset towards the direction of the feeding opening 3111 under the reset action of the second spring 315.

[0032] In addition, such as Figure 4 As shown, it also includes: The first guide frame 5 is fixedly installed on the frame 1. The first guide frame 5 has a recessed first guide rail 51 on the side facing the second guide frame 6. The first guide part 323 and the first guide rail 51 are engaged to realize the sliding of the first chuck assembly 32 relative to the clamp body 31. The second guide frame 6 is fixedly installed on the frame 1. Specifically, the second guide frame 6 has a second guide rail 61 recessed on the side facing the first guide frame 5. The second guide part 333 and the second guide rail 61 are engaged to realize the sliding of the second chuck assembly 33 relative to the clamp body 31.

[0033] Specifically, both the first guide frame 5 and the second guide frame 6 include the following relative segments: a first left-right straight segment 701, a second front-back inclined segment 702, a third left-right straight segment 703, a fourth semicircular arc segment 704, a fifth left-right straight segment 705, a sixth semicircular arc segment 706, a seventh left-right straight segment 707, an eighth up-down inclined segment 708, a ninth left-right straight segment 709, a tenth front-back inclined segment 710, an eleventh left-right straight segment 711, a twelfth front-back inclined segment 712, a thirteenth left-right straight segment 713, a fourteenth front-back inclined segment 714, and a fifteenth left-right straight segment 715. The spacing between the left and right straight segments 701, the spacing between the two eleventh left and right straight segments 711, and the spacing between the two fifteenth left and right straight segments 715 are all t1. The spacing between the two third left and right straight segments 703, the spacing between the two fourth semicircular segments 704, the spacing between the two fifth left and right straight segments 705, the spacing between the two sixth semicircular segments 706, the spacing between the two seventh left and right straight segments 707, the spacing between the two eighth vertically inclined segments 708, and the spacing between the two ninth left and right straight segments 709 are all t2. Wherein, t1 > t2.

[0034] Among them, the feeding station 121 and the diameter screening station 122 correspond to the first left and right straight segment 701, the length screening station 123 corresponds to the fifth left and right straight segment 705, the positioning station 124 corresponds to the ninth left and right straight segment, the tenth forward and backward inclined segment 710, the eleventh left and right straight segment 711, the twelfth forward and backward inclined segment 712, and the thirteenth left and right straight segment 713, the grinding station 125 corresponds to the thirteenth left and right straight segment 713, and the unloading station 126 corresponds to the fifteenth left and right straight segment 715.

[0035] like Figures 9-10As shown, when the tooling fixture 3 is located at the loading station 121, the loading opening 3111 is set upwards and the unloading opening 3112 is set downwards. The first guide part 323 and the second guide part 333 respectively cooperate with the first left and right straight segments 701 of the first guide frame 5 and the first left and right straight segments 701 of the second guide frame 6, so that the distance between the first clamping assembly 32 and the second clamping assembly 33 is s1. This distance makes the distance between the first clamping assembly 32 and the second clamping assembly 33 too far, and they do not have clamping ability. At this time, the copper rod 9 can be placed into the clamping area from above the loading opening 3111 downwards. It should be noted that due to the setting of the lower unloading opening 3112, the diameter of the placed copper rod 9 needs to be greater than d2. If the diameter of the placed copper rod 9 is less than d2, it will be screened out through the diameter screening station 122.

[0036] like Figure 9 , Figure 11 As shown, it also includes a diameter screening tray 81. The front and rear sides of the diameter screening tray 81 are fixedly installed below the two first left and right straight sections 701 by bolts or other means to form a fixed setting. The diameter screening tray 81 is provided with a screening opening 811 at the diameter screening station 122. The width of the screening opening 811 is d3, where d3≥d2. When the tooling fixture 3 is located at the loading station 121, the diameter screening tray 81 is located below the unloading opening 3112, so that even if the diameter of the copper rod 9 placed in the clamping area 311 is less than d2, the copper rod 9 cannot be completely removed from the clamping area 311 under the support of the diameter screening tray 81. That is, the copper rod 9 falls to the maximum extent and is supported by the diameter screening tray 81. In addition, the tooling fixture 3 will push the copper rod 9 to roll to the right during the rightward transmission process. When the tooling fixture 3 is located at the diameter screening station 122, since the first guide part 323 and the second guide part 333 are always in cooperation with the first left and right straight segments 701 of the first guide frame 5 and the first left and right straight segments 701 of the second guide frame 6, the distance between the first clamping assembly 32 and the second clamping assembly 33 is s4, which is equal to s1. This distance makes the distance between the first clamping assembly 32 and the second clamping assembly 33 too far, and they do not have clamping ability. Similarly, the loading opening 3111 is set upward and the unloading opening 3112 is set downward. The screening opening 811 is located below the unloading opening 3112, so that the support of the diameter screening tray 81 is released, and the copper rod 9 can fall downward through the screening opening 811 to complete the unloading of the copper rod 9 whose diameter does not meet the requirements.

[0037] Afterwards, the copper rod 9, which has been screened by diameter, is conveyed to the right by the tooling fixture 3. Under the action of the second front and rear inclined section 702, the first chuck assembly 32 and the second chuck assembly 33 move closer to each other, and the clamping of the copper rod 9 is completed at the third left and right straight section 703.

[0038] like Figure 11 As shown, while maintaining the clamping effect on the copper rod 9, the tooling fixture 3 moves along the fourth semicircular arc segment 704, the fifth left and right straight line segment 705, and the sixth semicircular arc segment 706. When the tooling fixture 3 is located at the length screening station 123 corresponding to the fifth left and right straight line segment 705, the loading opening 3111 is set downward and the unloading opening 3112 is set upward. The first guide part 323 and the second guide part 333 respectively cooperate with the fifth left and right straight line segment 705 of the first guide frame 5 and the fifth left and right straight line segment 705 of the second guide frame 6, so that the distance between the first chuck assembly 32 and the second chuck assembly 33 is less than The distance s5 of s1 makes the spacing between the first chuck assembly 32 and the second chuck assembly 33 closer, thus having clamping capability. If the length of the copper rod 9 meets the requirements, it will be conveyed by the tooling fixture 3 when passing through the fifth left and right straight section 705 due to the clamping of the first chuck assembly 32 and the second chuck assembly 33. If the length of the copper rod 9 is too small, it will not be able to be clamped by the first chuck assembly 32 and the second chuck assembly 33. When it passes through the fourth semi-circular arc section 704, the fifth left and right straight section 705, or the sixth semi-circular arc section 706, it will leave the feeding opening 3111 under the action of gravity and will be screened out through the length screening station 123.

[0039] Afterwards, the copper rod 9, after being selected by length, is transported along with the tooling fixture 3 through the sixth left and right straight section, the seventh up and down inclined section, and the eighth left and right straight section, and then returns to the same height as the first left and right straight section 701 to continue its transmission.

[0040] like Figure 13 , Figure 14As shown, this embodiment also includes a positioning plate 82, which is disposed at the positioning station 124. The left and right sides of the positioning plate 82 are fixedly installed on the ninth left and right straight segment 709 and the thirteenth left and right straight segment 713 by bolts or other means to make the positioning plate 82 fixedly installed. Specifically, the positioning plate 82 includes a first horizontal plate 821, an inclined plate 822 and a second horizontal plate 823 connected in sequence. The height of the first horizontal plate 821 is lower than the height of the second horizontal plate 823. The left part of the first horizontal plate 821 corresponds to the ninth left and right straight segment 709, the middle part corresponds to the tenth forward and backward inclined segment 710, and the right part corresponds to the eleventh left and right straight segment 711. The inclined plate 822 corresponds to the tenth left and right straight segment 711. The first horizontal horizontal plate 823 has a left-right straight segment 711, a left-right straight segment 711 corresponding to the eleventh horizontal horizontal segment 711, a middle segment corresponding to the twelfth forward-backward inclined segment 712, and a right-right segment corresponding to the thirteenth horizontal horizontal segment 713. When the tooling fixture 3 is located at the positioning station 124, the loading opening 3111 faces upwards, the unloading opening 3112 faces downwards, the positioning support plate 82 is located below the unloading opening 3112, and the height difference between the first rotating chuck 322 relative to the rotation axis of the first sliding seat 321 and the second horizontal plate 823 is h. The distance between the plane of the two first support positions 3121 and the rotation axis of the first rotating chuck 322 relative to the first sliding seat 321 is k. Where h = .

[0041] To prevent collisions between the copper rod 9 and the first support 312 during subsequent rotation and grinding, the axis of the copper rod 9 must be coaxial with the axis of rotation of the first rotating chuck 322 relative to the first sliding seat 321. Alternatively, the axis of the copper rod 9 must lie between the axis of rotation of the first rotating chuck 322 relative to the first sliding seat 321 and the plane containing the two first support positions 3121, i.e., the radius r of the copper rod 9 ≤ And because h= Then d2 / 2 < r < The copper rod 9 rises upwards, that is, from Figure 15 State transition to Figure 16 In this state, the distance between the first rotating chuck 322 and the top of the copper rod 9 relative to the rotation axis of the first sliding seat 321 is x=2r-h, where when r is close to the minimum value d2 / 2, x is close to the minimum value d2-h, so that the copper rod 9 with a radius of d2-h can be ground.

[0042] Therefore, when the tooling fixture 3 passes the positioning support plate 82 from left to right, the copper rod 9 passes the first horizontal plate 821, the inclined plate 822 and the second horizontal plate 823 in sequence, so that the final distance between the bottom of the copper rod 9 and the rotation axis of the first rotating chuck 322 relative to the first sliding seat 321 is h, and the copper rod 9 is finally uniformly polished into a shape of d2-h.

[0043] It should be noted that the copper rod 9 has a large weight, which can press the second support part 313 down completely. When the copper rod 9 is located on the second horizontal plate 823, the conveying speed of the tooling fixture 3 is relatively slow. The copper rod 9 is supported, and the second spring 315 drives the second support part 313 upward. Through this force, the copper rod 9 is centered from left to right, which basically makes the axis of the copper rod 9 and the axis of rotation of the first rotating chuck 322 relative to the first sliding seat 321 on the same vertical plane.

[0044] Furthermore, the first guide frame 5 facing the second guide frame 6 has abutment surfaces 52 on both sides of the width of the first guide rail 51. Two elastic conductive elements 324 are provided on the first sliding seat 321, and each elastic conductive element 324 abuts against different abutment surfaces 52. In addition, a second power motor (not shown in the figure) is fixedly installed inside the first sliding seat 321 by bolts or other means. In this embodiment, the second power motor is a hollow shaft motor so that the first rotating chuck 322 is inserted into the output hole of the second power motor and achieves rotation output under the operation of the second power motor. In addition, each abutment surface 52 is provided with a conductive rail 53 at the grinding station 125. When the tooling fixture 3 is located at the grinding station 125, the elastic conductive element 324 and the conductive rail 53 contact each other to drive the second power motor to rotate.

[0045] Therefore, under the elastic contact of the elastic conductive element 324 and the conductive rail 53, the second power motor is powered on to drive the copper rod 9 to rotate at high speed. Then, the copper rod 9 can be polished in the circumferential direction by passing through the polishing mechanism 4.

[0046] It should be noted that the surface of the first guide frame 5 needs to be coated with glue or sprayed with an insulating layer so that the conductive rail 53 and the first guide frame 5 are insulated from each other.

[0047] When the tooling fixture 3 is located at the grinding station 125, the loading opening 3111 is set upward and the unloading opening 3112 is set downward. The distance between the first chuck assembly 32 and the second chuck assembly 33 is s2. This distance makes the distance between the first chuck assembly 32 and the second chuck assembly 33 relatively close, ensuring the clamping of the copper rod 9.

[0048] It should be noted that, in order to prevent the copper rod 9 from being deformed during clamping, an elastic layer of a certain thickness is set on the first rotating chuck 322 and the second rotating chuck 332, so that the copper rod 9 within a certain error range can be effectively clamped.

[0049] Preferably, the number of polishing mechanisms 4 is multiple, so that the polishing quality is guaranteed by polishing through multiple sets of polishing mechanisms 4.

[0050] like Figure 18As shown, the grinding mechanism 4 includes a first power motor 41, a grinding roller 42, a lifting mounting frame 43, a lifting sliding frame 44, a lifting top block 45, a lifting top rod 46, an elastic top rod 47, and a lifting spring 48. The lifting mounting frame 43 is fixedly installed on the frame 1 by bolts or other means and is located in the conveying and grinding area 12. The lifting sliding frame 44 and the lifting top block 45 are mounted on the lifting mounting frame 43 by the cooperation of guide rails and sliders, and the lifting top block 45 is located below the lifting sliding frame 44. The lifting top rod 46 is threaded into the lifting mounting frame 43. The bottom of the lifting top rod 46 is provided with a sprite head, and the top and the lifting top block 45 are rotatably connected by a push bearing, so that the lifting top rod 46... The lifting mechanism is used to drive the lifting top block 45 to rise and fall. The elastic top rod 47 is threadedly fitted to the lifting mounting frame 43. The top of the elastic top rod 47 is provided with a sprite head. The lifting spring 48 is compressed and set below the elastic top rod 47 and above the lifting sliding frame 44. The lifting of the elastic top rod 47 is used to adjust the compression degree of the lifting spring 48. The grinding roller 42 is rotatably mounted on the lifting sliding frame 44 using ball bearings. The first power motor 41 is fixedly mounted on the frame 1 by bolts or other means and is located at the motor mounting position. The first power motor 41 and the grinding roller 42 are connected by a belt and pulley so that the rotation of the first power motor 41 can drive the grinding roller 42 to rotate at high speed for grinding.

[0051] Therefore, by adjusting the position of the lifting top block 45 of different grinding mechanisms 4, the lifting top block 45 of the left grinding mechanism 4 can be positioned higher and the lifting top block 45 of the right grinding mechanism 4 can be positioned lower, thus gradually performing grinding.

[0052] Preferred, such as Figure 19 As shown, in this embodiment, the angle between the axial direction of the grinding roller 42 and the length direction of the clamping area 311 is α, where 5° < α < 10°, so that the grinding roller 42 with a certain inclination can better grind the copper rod 9.

[0053] It should be noted that the rotation direction of the grinding roller 42 needs to be the same as the rotation direction of the copper rod 9, that is, clockwise or counterclockwise, so as to achieve a better grinding effect.

[0054] like Figure 20As shown, this embodiment also includes a feeding tray 83, which is set at the feeding station 126. Specifically, the left front and rear sides of the feeding tray 83 are fixedly installed on the thirteenth or so straight section 713 by bolts or the like, and the right front and rear sides are fixedly installed on the fifteenth or so straight section 715 by bolts or the like, so that the feeding tray 83 is fixedly set. In addition, the right side of the feeding tray 83 is provided with a dropping opening 831. When the tooling fixture 3 is located at the feeding station 126, the loading opening 3111 is set upward and the dropping opening 3112 is set downward. The distance between the first clamping assembly 32 and the second clamping assembly 33 is s3. This distance makes the distance between the first clamping assembly 32 and the second clamping assembly 33 too far, so that it does not have clamping ability.

[0055] Therefore, the polished copper rod 9 is released from clamping after passing through the fourteenth forward and backward inclined section 714, and then the copper rod 9 is transported to the right under the support of the unloading tray 83, and falls to the unloading opening 831 to complete the unloading.
