Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and in particular to a cotton picker spindle polishing device. Background Technology

[0002] As a key component of horizontal cotton pickers, the spindle is consumed in large quantities. Electroplating the spindle during production can effectively reduce wear and tear, improve wear resistance and service life. Pre-polishing is required before electroplating to improve the plating effect, resulting in a stronger bonding strength between the plating layer and the substrate on the spindle surface, preventing plating peeling and insufficient thickness. However, due to the complex surface structure of the spindle, existing polishing equipment has poor polishing effect and low polishing efficiency. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a cotton picker spindle polishing device, which achieves better polishing results and higher polishing efficiency on the surface of the picker spindle.

[0004] The cotton harvester spindle polishing device according to an embodiment of the present invention includes a base, a rotating frame, multiple cylinder holders, multiple polishing cylinders, and a drive mechanism. The rotating frame is rotatably mounted on the base via a first shaft. The multiple cylinder holders are disposed on the rotating frame and arranged around the axis of the first shaft. The multiple polishing cylinders are respectively placed in the multiple cylinder holders and can be removed from the cylinder holders. The multiple polishing cylinders in the same group are arranged along the axial direction of the first shaft. The polishing cylinders are used to load spindles, abrasives, and polishing liquid. The drive mechanism is disposed on the base and connected to the rotating frame to drive the rotating frame to rotate.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0037] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0038] The following is for reference. Figures 1 to 6 This invention describes a cotton picker spindle polishing device according to an embodiment of the present invention.

[0039] refer to Figures 1 to 6 As shown, the cotton picker spindle polishing device according to an embodiment of the present invention includes a base 100, a rotating frame 200, multiple cylinder chambers 300, multiple polishing cylinders 400, and a drive mechanism 500.

[0040] The rotating frame 200 is rotatably mounted on the base 100 via a first shaft 201. Specifically, a first shaft 201 can be provided at each end of the rotating frame 200 in the left and right directions. The two first shafts 201 are coaxial and can extend in the left and right directions. Both first shafts 201 are rotatably mounted on the base 100 via bearing seats 202. The lengths of the first shafts 201 on the two sides of the rotating frame 200 can be different. The first shaft 201 on the left side can be 50mm long and is assembled to the left support part of the base 100 via the bearing seat 202. The first shaft 201 on the right side can be 140mm long and is assembled to the right support part of the base 100 via the bearing seat 202. The bearing seats 202 are fixed to the base 100 with bolts.

[0041] Multiple cylindrical chambers 300 are mounted on the rotating frame 200. These chambers 300 are arranged around the axis of the first shaft 201. For example, there can be four cylindrical chambers 300, which can be evenly arranged around the axis of the first shaft 201. The polishing cylinders 400 can include four sets, each set placed within one of the four cylindrical chambers 300 and removable from the chambers. A single set of polishing cylinders 400 includes five polishing cylinders 400, arranged axially along the first shaft 201. The polishing cylinders 400 are used to hold the pick-up bar 900, abrasive, and polishing fluid.

[0042] A drive mechanism 500 is mounted on the base 100 and connected to the rotating frame 200 to drive the rotating frame 200 to rotate. For example, the drive mechanism 500 may include a motor 501, a first pulley 502, a second pulley 503, and a transmission belt 504. The diameter of the first pulley 502 is smaller than the diameter of the second pulley 503. The first pulley 502 is coaxially connected to the motor 501, and the second pulley 503 is coaxially connected to the rotating frame 200. The transmission belt 504 is installed between the first pulley 502 and the second pulley 503. Starting the motor 501 will drive the rotating frame 200 to rotate via the transmission belt 504. The structure is simple and easy to operate. It should be noted that the drive mechanism 500 can also have other structures; for example, the rotating frame 200 can also be driven to rotate by the motor 501 and a gear reducer.

[0043] In this application, a polishing ingot 900 to be polished, abrasive, and polishing fluid are added to each polishing cylinder 400. Then, multiple polishing cylinders 400 are respectively placed into multiple cylinder holders 300. Finally, the drive mechanism 500 is activated, which drives the rotating frame 200 to rotate at high speed around the axis of the first shaft 201. The rotating frame 200 then drives the multiple polishing cylinders 400 in the multiple cylinder holders 300 to move at high speed around the axis of the first shaft 201. During the high-speed movement of the polishing cylinders 400, the abrasive and polishing fluid inside can collide with the surface of the ingot 900 to be polished at high frequency, thereby polishing the surface of the ingot 900. This not only removes burrs from the surface of the ingot 900, but also passivates the surface of the ingot 900, eliminating defects such as cracks, pits, and bumps on the surface of the ingot 900, laying a good foundation for subsequent electroplating.

[0044] In this application, multiple cylinder chambers 300 are provided, and multiple polishing cylinders 400 are placed in each cylinder chamber 300. Each polishing cylinder 400 contains an appropriate amount of picks 900, abrasive and polishing fluid. In this way, the abrasive can concentrate, uniformly and comprehensively polish an appropriate number of picks 900, resulting in better polishing effect. Moreover, multiple picks 900 can be polished at the same time, resulting in higher polishing efficiency.

[0045] It is understood that, in addition to polishing, the cotton picker spindle polishing device of this application can also polish other objects with similar size and structure to the spindle 900, which will not be elaborated here.

[0046] refer to Figures 1 to 3 As shown, in some embodiments of this utility model, the top of the front end of the cylinder chamber 300 is provided with multiple flip covers 301 corresponding to the multiple polishing cylinders 400 inside it. One end of the flip cover 301 is hinged to the cylinder chamber 300, and the other end of the flip cover 301 is detachably connected to the cylinder chamber 300.

[0047] In this application, each polishing cylinder 400 in the cylinder holder 300 is provided with a flip cover 301, and the flip cover 301 is installed on the top of the front end of the cylinder holder 300, which makes it more convenient for staff to take out and place the polishing cylinder 400.

[0048] refer to Figure 2 and Figure 4 As shown, in some embodiments of this utility model, the cylindrical base 300 is rotatably mounted on the rotating frame 200 via a second shaft 302. The second shaft 302 is parallel to the first shaft 201. For example, the rotating frame 200 may have a ring structure on both sides, and the ring structure may have four mounting holes. The cylindrical base 300 may have a second shaft 302 at both ends in the left and right directions, and the second shaft 302 is rotatably mounted in the corresponding mounting hole. The cotton picker's spindle polishing device also includes an eccentric wheel 600, a hollow rotating wheel 700, and multiple connecting rods 800. The eccentric wheel 600 is sleeved on the first shaft 201 and rotates relative to the first shaft 201. The axis of the eccentric wheel 600 is parallel to the axis of the first shaft 201 and there is a gap between them. The hollow rotating wheel 700 is rotatably sleeved on the eccentric wheel 600. The hollow rotating wheel 700 is provided with multiple third shafts 701 corresponding to the second shaft 302. The third shafts 701 are parallel to the second shaft 302. The connecting rods 800 are provided with pin holes at both ends and are rotatably sleeved on the corresponding second shaft 302 and third shaft 701 through two pin holes respectively.

[0049] If the barrel holder 300 is directly fixedly mounted on the rotating frame 200, and the barrel holder 300 rotates with the rotating frame 200, the orientation of the cover 301 of the barrel holder 300 will be completely different, making it inconvenient to open the cover 301 and to take out or put in the polishing barrel 400. In this application, the hollow rotating wheel 700 is rotatably sleeved on the eccentric wheel 600, the eccentric wheel 600 is sleeved on the first shaft 201 and rotates relative to the first shaft 201. The axis of the eccentric wheel 600 is parallel to the axis of the first shaft 201 and there is a gap between them. The third shaft 701 of the hollow rotating wheel 700 and the second shaft 302 of the barrel holder 300 are hinged to a connecting rod 800, thus roughly forming a parallel four-bar linkage, and there are four parallel four-bar linkages. In this way, when the barrel chamber 300 rotates with the rotating frame 200, the opening cover 301 of all barrel chambers 300 can always face the same direction, such as facing forward and upward, which makes it convenient to open the opening cover 301 and convenient to take out and put in the polishing barrel 400.

[0050] It is understandable that the eccentric wheel 600 is mounted on the first shaft 201 and rotates relative to the first shaft 201. That is, when the rotating frame 200 rotates, it does not drive the eccentric wheel 600.

[0051] refer to Figure 6As shown, in some embodiments of this utility model, the cylinder chamber 300 is provided with a hook 303 corresponding to the flip cover 301, the bottom of the front end of the flip cover 301 is provided with a connecting part 304, the connecting part 304 is provided with a through hole, a first bolt 305 is passed through the through hole, a first nut 306 is sleeved on the top of the first bolt 305, the first nut 306 is located above the connecting part 304, and the bottom end of the first bolt 305 is provided with a snap-fit ​​part 307, which snaps with the hook 303.

[0052] In this embodiment, after the cover 301 closes the cylinder chamber 300, the snap-fit ​​part 307 is snapped into the snap-fit ​​hook 303, and then the first nut 306 is tightened, so that the cover 301 and the cylinder chamber 300 are securely connected and fixed, which can prevent the polishing cylinder 400 inside from moving at will.

[0053] refer to Figure 6 As shown, in some embodiments of this utility model, two adjacent hinged covers 301 are provided with corresponding pin seats 308 on their adjacent sides, and a locking pin 309 is inserted between the two corresponding pin seats 308. For example, the five hinged covers 301 of the cylinder chamber 300 have a total of four locking pins 309. When removing the parts after polishing, first remove the four locking pins 309 one by one, and then unscrew each first nut 306 to open the hinged cover 301.

[0054] In this embodiment, a locking pin 309 is provided to make the connection between two adjacent flip covers 301 more secure and reliable.

[0055] refer to Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments of this utility model, the polishing cylinder 400 is provided with a handle 401 at the top, and the cover 301 is provided with a relief groove 310, with the handle 401 passing through the relief groove 310.

[0056] In this embodiment, the polishing cylinder 400 is provided with a handle 401 for easy picking up and putting down of the polishing cylinder 400. The cover 301 is provided with a relief groove 310, and the handle 401 passes through the relief groove 310. In this way, not only can the movement of the polishing cylinder 400 be further restricted, but the handle 401 will not occupy the space inside the cylinder seat chamber 300, making the overall size of the cotton picking machine spindle polishing device of this application smaller.

[0057] refer to Figure 5As shown, in some embodiments of this utility model, the polishing cylinder 400 is provided with multiple polishing chambers, and the multiple polishing chambers have openings 402 on the same side along the axial direction of the first shaft 201. The polishing cylinder 400 is provided with a sealing cover 403, which opens and closes all openings 402. For example, the multiple polishing chambers can be arranged in an array, and each polishing chamber can hold a suitable number of picks 900. The polishing chambers can extend along the axial direction of the first shaft 201, and the multiple polishing chambers have openings 402 on the right side along the axial direction of the first shaft 201. The sealing cover 403 can be provided on the right side of the polishing cylinder 400, so that the sealing cover 403 opens and closes all openings 402.

[0058] In this embodiment, the polishing cylinder 400 is provided with multiple polishing chambers, each of which can hold an appropriate amount of picks 900, abrasive, and polishing fluid. This allows the abrasive to concentrate, uniformly, and comprehensively polish the appropriate number of picks 900, resulting in better polishing performance. A sealing cover 403 is provided to prevent the abrasive and water from flowing out of the polishing chambers.

[0059] refer to Figure 5 As shown, in some embodiments of this utility model, the polishing cylinder 400 is provided with a second bolt 404. For example, the second bolt 404 can be provided in the middle of the right side of multiple polishing chambers. The sealing cover 403 is provided with a sleeve hole 405, and the second bolt 404 is sleeved through the sleeve hole 405. The second bolt 404 is sleeved with a second nut 406. The second nut 406 abuts against the side of the sealing cover 403 away from the polishing cylinder 400. The sealing cover 403 is provided with multiple limiting holes 407. The polishing cylinder 400 is provided with multiple limiting pins 408, and the multiple limiting pins 408 are respectively inserted through the multiple limiting holes 407.

[0060] In this embodiment, the second nut 406 and the second bolt 404 work together to lock the sealing cover 403, resulting in a better sealing effect. Furthermore, the engagement of the limiting pin 408 and the limiting hole 407 prevents the sealing cover 403 from rotating arbitrarily during the high-speed rotation of the polishing cylinder 400, further enhancing the sealing effect and effectively preventing abrasive and water from flowing out of the polishing chamber.

[0061] refer to Figure 1 As shown, in some embodiments of this utility model, the base 100 is provided with a receiving compartment 101, the rotating frame 200 is located in the receiving compartment 101, the top of the front end of the receiving compartment 101 is provided with a pick-up and put-out port 102, and the base 100 is provided with a door 103, which is used to open and close the pick-up and put-out port 102.

[0062] In this embodiment, the rotating frame 200 is located inside the housing 101 and is provided with a door 103, which can reduce the dust adhesion of the rotating frame 200 and its components. The top of the front end of the housing 101 is provided with a pick-up and drop-off port 102, which makes it more convenient to pick up and drop the polishing cylinder 400.

[0063] refer to Figure 1 As shown, in some embodiments of this utility model, one end of the hatch 103 is connected to at least two C-shaped hooks 104, the edge of the top of the take-up and put-out port 102 extends into the C-shaped hooks 104, and the other end of the hatch 103 is hinged to the base 100 with at least two hydraulic cylinders 105.

[0064] In this embodiment, the opening and closing of the hatch 103 and the loading / unloading port 102 can be driven by the extension and retraction of the hydraulic cylinder 105, which is simple and convenient to operate.

[0065] Furthermore, since the hatch 103 is not a flat structure but has an approximately L-shaped cross-section, if a hinge is used to connect the hatch 103 and the base 100, the hatch 103, the base 100, and the hydraulic cylinder 105 would form a zero-degree-of-freedom mechanism, making it impossible for the hydraulic cylinder 105 to operate and the hatch 103 to rotate. In this application, however, the hatch 103 is connected to at least two C-shaped hooks 104, with the edge of the top of the loading / unloading port 102 extending into the C-shaped hooks 104. This not only limits the installation of the hatch 103 but also prevents the hatch 103 from being difficult to rotate.

[0066] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
