Description

Technical Field

[0001] This application relates to the field of polishing equipment, and more specifically to an automatic polishing machine for metal rings. Background Technology

[0002] Currently, polishing metal rings requires the use of a specialized polishing machine. However, this machine is semi-automatic and can only polish the lower end and surrounding area of ​​the metal ring. After polishing the predetermined area, the operator still needs to manually rotate the metal ring to polish the next predetermined area. The specific working process is as follows: (1) The operator first clamps and fixes the metal ring on the fixed frame so that the preset polishing position is located below the fixed frame; (2) The operator operates the sanding belt to press against the metal ring from the front and back of the preset polishing position; (3) The sanding belt runs continuously like a transmission belt under the drive of the equipment, so as to continuously polish the preset polishing position; (4) The fixed frame moves left and right under the drive of the cylinder so that the sanding belt can polish a larger area on both sides of the metal ring at the same time; (5) The fixed frame can rotate and flip back and forth with the polishing position of the metal ring as the center and under the drive of the rotary cylinder so that the sanding belt can polish the inner and outer sides of the metal ring; (6) The operator stops the machine and confirms whether the metal ring has been completely polished. If it has not been completely polished, the metal ring is manually rotated to adjust the next preset polishing position to the bottom of the fixed frame and return to step (1). Utility Model Content

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] Example 1

[0047] like Figure 1As shown, an automatic metal ring polishing machine includes a worktable 100, an abrasive belt 200 disposed on the surface of the worktable 100, a support frame 300 disposed on the surface of the worktable 100 and spanning above the abrasive belt 200, a power supply 700 disposed at any position on the worktable 100, a rotary clamping part 500 disposed on the support frame 300, a pneumatic clamping part 600 disposed on the support frame 300, a controller 800 disposed on the worktable 100, and a human body sensor 900 disposed on the front of the worktable 100.

[0048] The power supply and controller are electrically connected to the air pump, motor, controller, human body sensor and other electrical equipment to supply power and control them. The connection and control methods are existing technologies, and those skilled in the art can complete the connection and use without creative labor, so they will not be described in detail here.

[0049] The purpose of setting up a human body sensor is to detect whether an operator is approaching. If an operator approaches the equipment, the human body sensor will be triggered, and the controller will then stop the equipment to prevent the operator from being burned by flying residue. This effectively improves the safety of the equipment and better protects the personal safety of the operator.

[0050] like Figure 2 As shown, the sanding belt section 200 consists of two parallel sanding belt tracks 201 arranged longitudinally in the middle of the workbench 100, a lead screw assembly arranged between the two sanding belt tracks 201, two sanding belt cylinder mechanisms symmetrically arranged on the sanding belt tracks 201 and respectively cooperating with the lead screw assembly in opposite directions, two sanding belt polishing mechanisms symmetrically arranged on the sanding belt tracks 201 and located between the two sanding belt cylinder mechanisms, and a plurality of sanding belt sliders 202 respectively arranged at the bottom of the sanding belt cylinder mechanism and the sanding belt polishing mechanism and cooperating with the sanding belt tracks 201;

[0051] The belt abrasive cylinder mechanism and the belt abrasive polishing mechanism are provided with a protective upper shell 214.

[0052] The protective shell effectively isolates the residue generated during equipment operation from the main operating machinery of the sanding belt, preventing residue from being ejected into the motor or air pump, thus further protecting the safety of the equipment.

[0053] The belt polishing mechanism consists of a belt motor base 203, a belt motor 209 mounted on the belt motor base 203, a driven support plate 210 mounted on the belt motor base 203, a belt driven wheel assembly 212 mounted on the driven support plate 210, a belt 213 sleeved on the belt driven wheel assembly 212, and a belt drive belt 211 sleeved between the output shaft of the belt motor 209 and the belt driven wheel assembly 212.

[0054] When the belt sander motor is running, it will drive the driven pulley set of the sander belt to rotate through the sander belt drive belt. When the driven pulley set of the sander belt rotates, it will drive the sander belt to run. When the sander belt runs, it will polish the metal ring located between the two sander belts.

[0055] The belt sander cylinder mechanism consists of a belt sander cylinder base 204 and a belt sander cylinder 208 mounted on the belt sander cylinder base 204; the front end of the telescopic rod of the belt sander cylinder 208 is fixed to the belt sander motor base 203 adjacent to it.

[0056] The function of the belt polishing cylinder is to control the belt polishing mechanism with short strokes. For example, when the metal ring needs to rotate, the belt polishing cylinder moves the two belt polishing mechanisms in opposite directions, causing the belt to disengage from the surface of the metal ring and preventing scratches caused by friction between the belt and the metal ring during rotation. After the metal ring has finished rotating, the belt polishing cylinder moves the two belt polishing mechanisms towards each other, causing the belt to re-engage with the surface of the metal ring and avoiding polishing at that location.

[0057] The lead screw assembly consists of a sanding belt cylinder lead screw 205, which is mounted on the workbench 100, located between two sanding belt tracks 201, and can rotate under the drive of the sanding belt cylinder handwheel 206, and lead screw nuts 207, which are respectively mounted on two sanding belt cylinder bases 204 and can move synchronously towards or away from each other on the sanding belt cylinder lead screw 205.

[0058] The lead screw assembly is mainly used to control the large stroke movement of the belt abrasive cylinder mechanism. For example, when it is necessary to replace metal rings of different sizes, the belt abrasive cylinder mechanisms need to be moved apart to provide a relatively spacious area for clamping and positioning the product.

[0059] like Figure 3As shown, the support frame 300 consists of two sets of horizontally arranged left and right displacement tracks 301 symmetrically arranged on the left and right sides of the sanding belt section 200; two support frame bases 303 respectively mounted on the two left and right displacement tracks 301 via left and right displacement sliders 302; a fixed frame 304 mounted on the workbench 100 and adjacent to any set of left and right displacement tracks 301; a left and right displacement cylinder 305 mounted on the fixed frame 304 with the front end of the telescopic rod fixed to the adjacent support frame base 303; two horizontally mounted and coaxially arranged tilting bearings 307 respectively mounted on the two support frame bases 303; a tilting cylinder 306 mounted on the outer side of any support frame base 303 and capable of driving the tilting bearing 307 to rotate; and two frame fixing plates 308 respectively fixed to the inner sides of the two tilting bearings 307. The system comprises two clamping plate 309s inside the two frame fixing plates 308 for mounting the pneumatic clamping part 600, two vertical slide rail structures 310 respectively vertically and symmetrically mounted on the two frame fixing plates 308, vertical slide rail fixing plates 312 respectively fixed at both ends to the rear sides of the two vertical slide rail structures 310, a horizontal slide rail structure 314 horizontally mounted and simultaneously fixed to the vertical sliders of the two vertical slide rail structures 310, a vertical slider synchronization box 311 mounted on the top of the two vertical slide rail structures 310 and controlled by the vertical slide rail handwheel 313 to rise or fall synchronously on the two vertical sliders, and two horizontal sliders 315 mounted on the front of the horizontal slide rail structure 314 that can move synchronously towards or away from each other under the drive of the horizontal slide rail handwheel 316 and are used to mount the rotating clamping part 500.

[0060] The setup and usage of the left and right displacement cylinder and the tilting cylinder are basically the same as those of traditional polishing machines. However, compared to the manual start of traditional polishing machines, the left and right displacement cylinder and the tilting cylinder of this application can be automatically controlled by a controller, which further improves the intelligence of the product.

[0061] Compared to existing traditional polishing machines, one of the differences in this embodiment is that the height and spacing of the rotating clamping part can be adjusted by the vertical slide rail handwheel and the horizontal slide rail handwheel, so that the product can quickly and accurately clamp, fix and rotate metal rings of different sizes, which greatly improves the product's adaptability and usage efficiency.

[0062] like Figure 4As shown, the rotating clamping part 500 consists of a clamping base plate 501 fixed to the transverse slider 315 from the back, a clamping cylinder 502 disposed on the outer side of the front of the clamping base plate 501, a rotating drive wheel seat 507 disposed on the inner side of the front of the clamping base plate 501, a rotating drive wheel 508 disposed inside the rotating drive wheel seat 507, a stepper motor 510 disposed on the front of the rotating drive wheel seat 507 and connected to the rotating drive wheel 508 via a transmission component, and a stepper motor 510 disposed on the inner end of the front of the clamping base plate 501 and connected to the rotating drive wheel 508. The system comprises a driven wheel 509 with an annular groove that cooperates with the driven wheel 508, a clamping transmission plate 503 whose rear end is fixed to the front end of the telescopic rod of the clamping cylinder 502, a clamping transmission plate 503 whose front end is attached to the front of the clamping base plate 501 and passes through the rotary drive wheel seat 507, a clamping wheel 504 that is disposed at the front end of the clamping transmission plate 503 and cooperates with the driven wheel 509, a rear top plate 505 that is fixed to the inner end face of the clamping base plate 501, and a rear top wheel 506 that is disposed on the rear top plate 505 and cooperates with the driven wheel 509.

[0063] In use, the outer surface of the metal ring rests against the annular groove of the rotating driven wheel. The clamping cylinder controls the clamping wheel to press the metal ring firmly into the rotating driven wheel from its inner surface, thus fixing the metal ring. When the metal ring needs to be rotated, the stepper motor controls the rotating drive wheel to rotate via the transmission components. The rotating drive wheel then drives the rotating driven wheel to rotate, causing the metal ring to rotate under the influence of the rotating driven wheel.

[0064] The purpose of selecting a stepper motor is to improve the accuracy of rotation, thereby further enhancing the precision of controlling the rotation angle of the metal ring. The transmission component is a simple combination of existing transmission gears and shafts, a conventional technology in the field. Those skilled in the art can set it up and use it without creative effort, and therefore will not be elaborated upon here.

[0065] like Figure 5 , Figure 6 As shown, the pneumatic clamping part 600 consists of a first rotating block 601 fixed to the rear side of the clamping part fixing plate 309, a second rotating block 602 whose outer side is disposed at the rear end of the first rotating block 601 and perpendicular to the first rotating block 601, a clamping base plate 603 disposed on the inner side of the second rotating block 602, a clamping air pump 604 fixed on the clamping base plate 603, a clamping slide block 605 disposed on the front side of the clamping air pump 604, two "T"-shaped sliding seats 606 disposed in the slide groove of the clamping slide block 605 and capable of moving synchronously towards or away from each other under the drive of the clamping air pump 604, two front and rear clamping blocks 607 respectively disposed on the two sliding seats 606, front and rear clamping wheels 608 disposed at the ends of the front and rear clamping blocks 607, and an inner and outer clamping structure disposed on any one of the front and rear clamping blocks 607.

[0066] Rotating blocks No. 1 and No. 2 can be either rotatable or fixed structures. Their purpose is to ensure that the clamping structure is effectively kept away from the support frame base and the tail end of the clamping plate, so as to provide a more spacious operating space for the clamping structure, thereby reducing the interference of other structures on the clamping structure and ensuring the clamping effect of the product on the metal ring.

[0067] The clamping air pump can control the distance between the two clamping slide blocks, and by controlling the distance between the two clamping slide blocks, it can achieve the effect of clamping or releasing the two front and rear sides of the metal ring by the two front and rear clamping wheels. The setting and use of the clamping air pump are existing technologies, and those skilled in the art can complete its setting and use without creative labor, so they will not be described in detail here.

[0068] The internal and external clamping structure consists of an external clamping block 609 located on the upper side of the front and rear clamping blocks 607, an external clamping wheel 610 located on the side of the external clamping block 609 and simultaneously above the two front and rear clamping wheels 608, an external clamping groove 611 vertically penetrating the external clamping block 609, an external clamping adjusting bolt 612 penetrating the external clamping groove 611 and screwed onto the front and rear clamping blocks 607, a cylinder fixing seat 613 located on the side of the front and rear clamping blocks 607, a clamping cylinder 614 located on the cylinder fixing seat 613 with the movement direction of the telescopic rod perpendicular to the movement direction of the sliding seat 606, and a clamping transmission mechanism with one end fixed to the telescopic rod of the clamping cylinder 614 and the other end attached to the side wall of the external clamping block 609. The clamping transmission plate 615, the clamping wheel 617 which is disposed on the front side of the clamping transmission plate 615 and cooperates with the outer clamping wheel 610, the clamping wheel connecting block 616 disposed between the clamping wheel 617 and the clamping transmission plate 615, and the clamping wheel connecting block 616 which is disposed between the clamping wheel 617 and the clamping transmission plate 615, consists of a clamping limiting groove 618 that is horizontally penetrating the clamping transmission plate 615, a clamping limiting bolt 619 that is screwed into the side of the outer clamping block 609 through the clamping limiting groove 618, a connecting block positioning bolt 621 that is horizontally penetrating the clamping transmission plate 615 and tightened onto the clamping wheel connecting block 616 and is coaxial with the clamping wheel 617, and a connecting block rotating shaft bolt 620 that is horizontally penetrating the clamping transmission plate 615 and tightened onto the clamping wheel connecting block 616 and is parallel to the connecting block positioning bolt 621.

[0069] During use, the outer clamping wheel rests against the outer surface of the metal ring, while the clamping wheel, under the control of the clamping cylinder, presses the metal ring against the outer clamping wheel from the inner surface of the metal ring. Through the cooperation of the two front and rear clamping wheels, the outer clamping wheel, and the clamping wheel, the metal ring can be effectively limited, preventing displacement during the polishing process.

[0070] The clamping transmission plate 615 is provided with an arc-shaped groove centered on the central axis of the connecting block pivot bolt 620, and the connecting block positioning bolt 621 passes through the arc-shaped groove.

[0071] The arc-shaped groove allows the clamping wheel connecting block to rotate within the angle range of the arc-shaped groove, further improving the adjustable range of the clamping wheel. This enables the product to better match metal rings of different sizes, further enhancing the product's adaptability.

[0072] Example 2

[0073] The difference between this embodiment and embodiment 1 is that an auxiliary support structure 400 is provided on the transverse slide rail structure 314. The auxiliary support structure 400 consists of a vertical support rod that is vertically fixed to the front of the transverse slide rail structure 314, and two rollers that are arranged opposite to each other on the top of the vertical support rod and are used to clamp the front and rear sides of the top of the metal ring.

[0074] When processing large metal rings, an auxiliary support structure is installed to clamp the top of the metal ring to prevent it from deforming due to external forces when the equipment is turned over, thus ensuring the processing quality of the product.

[0075] The auxiliary support structure can be removed when not needed to avoid causing adverse interference during the processing of small metal rings.

[0076] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0077] Furthermore, the specific embodiments described above are exemplary.
