[0026] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] As attached Figure 1 As shown, the present invention provides a fully automatic and efficient grinding device for a retaining spring, comprising a first slideway 5 and a second slideway 7 that are located in the same horizontal plane and are parallel to each other.

[0028] A first material transfer trolley 6 and a second material transfer trolley 8 are slidably installed between the first slideway 5 and the second slideway 7 . The first material transfer trolley 6 and the second material transfer trolley 8 can move back and forth along the first slideway 5 and the second slideway 7 .

[0029] The first material storage module 1, the polishing table 3 and the second material storage module 4 are also installed in sequence on the ground or table between the first slide 5 and the second slide 7, and the first material storage module 1, the polishing table 3 and the second material storage module 4 are arranged in sequence along the length direction of the first slide 5.

[0030] A first blanking machine 2 and a second blanking machine are also installed below the first slide 5 ; the length directions of the two blanking machines are perpendicular to the length direction of the first slide 5 .

[0031] The first blanking machine 2 corresponds to the second material transfer vehicle 8 , and the second blanking machine corresponds to the first material transfer vehicle 6 .

[0032] The first storage module 1 and the second storage module 4 are used to place the retaining rings 105 to be ground.

[0033] The first material transfer cart 6 and the second material transfer cart 8 are used to transfer the retaining spring 105. The transfer process includes the first material transfer cart 6 grabbing the retaining spring 105 from the second storage module 4, and then arriving at the grinding table 3 to grind the outer ring, inner ring and first side of the retaining spring 105. Then the second material transfer cart 8 grabs the partially polished retaining spring 105 and moves it to the grinding table 3. The grinding table 3 grinds the second side of the retaining spring 105. After grinding, the second material transfer cart 8 places the retaining spring 105 on the first blanking machine 2. This action process continues until the retaining spring 105 in the second storage module 4 is polished; then the worker loads the retaining spring 105 into the second storage module 4. At this time, the actions of the second material transfer cart 8 and the first material transfer cart 6 are exchanged. The second material transfer cart 8 grabs the retaining spring 105 from the first storage module 1, and the first material transfer cart 6 places the polished retaining spring 105 on the second blanking machine.

[0034] The first storage module 1 and the second storage module 4 have the same structure. Figure 2 and attached Figure 3 As shown, the apparatus comprises a U-shaped first support 101, within which a first motor 102 is mounted. A material rack for placing a retaining ring 105 is detachably mounted on the top of the first support 101. A support ring 104 is mounted on the material rack and is driven to rise and fall by the first motor 102. The retaining ring 105 is placed on the support ring 104. Whenever the first transfer carriage 6 or the second transfer carriage 8 removes a retaining ring 105, the first motor 102 drives the support ring 104 to rise by the thickness of the retaining ring 105.

[0035] The material rack includes a guide cylinder 103 , a first bottom plate 107 is fixedly mounted on the bottom of the guide cylinder 103 , and the first bottom plate 107 is fixedly connected to the tops of the two side walls of the first support 101 by bolts.

[0036] A rotatable lead screw 108 is mounted within the guide cylinder 103. The first end of the lead screw 108 is rotatably engaged with a first bearing seat 113, and the second end is rotatably engaged with a second bearing seat 116. The first bearing seat 113 is bolted to the top of the guide cylinder 103, and the second bearing seat 116 is bolted to the bottom of the first base plate 107.

[0037] The second end of the lead screw 108 is connected to the output end of the first motor 102 through a coupling.

[0038] A nut slider 109 is installed on the lead screw 108, and a connecting plate 112 is installed on the top of the nut slider 109 through bolts. The lead screw 108 passes through the connecting plate 112 and is loosely fitted therewith.

[0039] Four L-shaped connecting arms 110 are fixedly mounted on the connecting plate 112 in a circumferential array. The horizontal portion of the connecting arm 110 is connected to the connecting plate 112 , and the vertical portion is connected to the bottom of the support ring 104 via bolts.

[0040] The support ring 104 is sleeved on the outside of the guide cylinder 103 and is loosely fitted with the guide cylinder 103 .

[0041] The support ring 104 is used to support the retaining spring 105. The support ring 104 is matched with the connecting arm 110 to ensure that the last retaining spring 105 placed on the support ring 104 can also be lifted high enough to facilitate the first and second material transfer vehicles 6 and 8 to grab.

[0042] The guide cylinder 103 is provided with a guide groove 111 for the connecting arm 110 to move.

[0043] As attached Figure 3 As shown, a first position switch 114 is installed on one of the connecting arms 110. When the connecting plate 112 rises to the maximum allowable height, the first position switch 114 touches the top wall of the guide cylinder 103. After the control receives the signal, it reminds the worker to prepare for loading.

[0044] A second in-position switch 115 is installed on the top of the first bottom plate 107. When the connecting plate 112 drops to the lowest allowed position, one of the connecting arms 110 touches the second in-position switch 115, and the first motor 102 stops rotating.

[0045] Two vertical first guide posts 106 are also installed on the top of the first base plate 107 by bolts. When the retaining ring 105 is placed on the support ring 104, the two holes on the retaining ring 105 are sleeved on the first guide posts 106 to ensure that the postures of all retaining rings 105 are the same.

[0046] The support ring 104 is provided with an avoidance groove matching the first guide post 106 .

[0047] The structure of the grinding table 3 is shown in the attached Figure 4 As shown, it includes a second support 301, and a grinding assembly 302 is fixed on the top of the second support 301 by bolts.

[0048] The structure of the grinding assembly 302 is shown in the attached Figure 5 As shown, it includes a first base 305, which is fixed on the top of the second support 301 by bolts.

[0049] Two sets of guide rails 312 are installed on the top of the first base 305 by bolts. A first slide 304 and a second slide 306 are slidably installed on each set of guide rails 312, and the first slide 304 and the second slide 306 are respectively located at the first end and the second end of the first base 305.

[0050] A second grinder 313 is detachably mounted on the first slide 304 via a second protective cover 314, and a first grinder 311 is detachably mounted on the second slide 306 via a first protective cover 310. The second grinder 313 and the first grinder 311 have the same structure and are mirror-imaged.

[0051] The first protective cover 310 and the second protective cover 314 also have the same structure.

[0052] The bottom of the first end of the first base 305 is installed with a first cylinder 303 by bolts. The first cylinder 303 is a double-piston cylinder, and a second connecting block 316 is installed between its two pistons by bolts. The second connecting block 316 is also connected to the first end of the second connecting plate 315 by bolts; the second end of the second connecting plate 315 is connected to the first slide 304 by bolts, thereby realizing the driving of the first slide 304 by the first cylinder 303.

[0053] A second cylinder 307 is installed at the bottom of the second end of the first base 305 by bolts. The second cylinder 307 is a double-piston cylinder, and a first connecting block 308 is installed between its two pistons by bolts. The first connecting block 308 is also connected to the first end of the first connecting plate 309 by bolts; the second end of the first connecting plate 309 is connected to the second slide 306 by bolts, thereby realizing the driving of the second slide 306 by the second cylinder 307.

[0054] The output ends of the two first grinders 311 are respectively equipped with a first grinding head and a second grinding head. Similarly, the output ends of the two second grinders 313 are also respectively equipped with a first grinding head and a second grinding head. The first grinding head has a smaller diameter than the second grinding head and is more suitable for grinding the outer and inner rings of the retaining spring 105. The second grinding head is more suitable for grinding the two side surfaces of the retaining spring 105.

[0055] Taking the first material transfer vehicle 6 as an example, the first material transfer vehicle 6 grabs the retaining spring 105 and arrives at the grinding table 3, and the first grinder 311 equipped with a first grinding head extends out for grinding. After the first grinder 311 completes the operation, it returns to its original position, and the first grinder 311 equipped with a second grinding head operates to grind one side of the retaining spring 105; the second material transfer vehicle 8 grabs the retaining spring 105 and moves it to the grinding table 3, and the second grinder 313 equipped with a second grinding head operates to complete the grinding of the retaining spring 105.

[0056] The first protective cover 310 and the second protective cover 314 have the same structure. Figure 6 As shown, it includes a U-shaped cover 317 with a plurality of heat dissipation holes 318 formed on the cover 317 .

[0057] Ear plates 319 are provided on both sides of the cover body 317 , and the ear plates 319 are used to connect with the first slide seat 304 and the second slide seat 306 through bolts.

[0058] End plates 320 are provided at both ends of the cover 317 .

During installation, the main body 321 is placed in the corresponding first protective cover 310 and second protective cover 314 , and is clamped between the two end plates 320 of the cover body 317 .

[0060] The use of this protective cover structure not only facilitates assembly and disassembly, but also maintains the stability of the installation of the first grinder 311 and the second grinder 313 , and can also achieve rapid assembly and disassembly.

[0061] The first material transfer vehicle 6 and the second material transfer vehicle 8 have the same structure. Figure 8 and the attached Figure 10 As shown, it includes a beam 601, a second slide rail 602 is installed on the beam 601, a fifth slide seat 603 is slidably installed on the second slide rail 602, a lifting component 604 that can move up and down is installed on the fifth slide seat 603, and a material transfer head 608 is installed at the bottom of the lifting component 604 through bolts.

[0062] A third slide 606 is mounted on the first end of the crossbeam 601 via bolts, and a third motor 607 is mounted on the third slide 606 .

[0063] A fourth slide 609 is mounted on the second end of the beam 601 via bolts.

[0064] The first slide 5 includes a second base 501, on the top of which a first slide rail 504 and a first rack 505 are installed by bolts. The aforementioned third slide 606 slides in cooperation with the first slide rail 504, and the output end of the third motor 607 is fixedly mounted with a first gear which meshes with the first rack 505.

[0065] A plurality of photoelectric gates 503 are installed on the second base 501 to limit the travel of the first material transfer vehicle 6 and the second material transfer vehicle 8 .

[0066] The second slide 7 includes a third base, and a fourth slide rail that is slidably matched with the fourth slide seat 609 is installed on the top of the third base through bolts.

[0067] Buffer blocks 502 are also installed on the second base 501 and the third base. The buffer blocks 502 are arranged at the ends of the travels of the first material transfer trolley 6 and the second material transfer trolley 8.

[0068] The matching relationship between the fifth slide 603 and the lifting component 604 is shown in the attached figure. Figure 10 As shown, the lifting component 604 includes a longitudinal beam 610, on which a third rack 611 and a third slide rail 612 are installed by bolts, and the fifth slide 603 slides in cooperation with the third slide rail 612; a fourth motor 614 is installed on the fifth slide 603, and a second gear is fixedly installed at the output end of the fourth motor 614, and the second gear is engaged with the third rack 611.

[0069] A translation motor 613 is also mounted on the fifth slide 603 . A third gear is fixedly mounted on the output end of the translation motor 613 . The third gear is engaged with a second rack 605 mounted on the crossbeam 601 via bolts.

[0070] The material transfer head 608 is detachably mounted on the bottom of the longitudinal beam 610 .

[0071] The structure of the material transfer head 608 is shown in the attached Figure 11 As shown, it includes a connecting seat 616, the top of the connecting seat 616 is detachably connected to the bottom of the longitudinal beam 610 by bolts; a fifth motor 615 is installed on one side of the connecting seat 616 by bolts, and the output end of the fifth motor 615 passes through the connecting seat 616 and is fixedly connected to the seat plate 621; a third cylinder 618 is installed on the side of the seat plate 621 away from the connecting seat 616 by bolts.

[0072] In the initial state, the output end of the third cylinder 618 is vertically downward, and a horizontal material transfer tray 619 is installed; specifically, the output end of the third cylinder 618 is provided with a thread, which passes through the material transfer tray 619, and nuts are installed on both sides of the material transfer tray 619 to fix the material transfer tray 619.

[0073] The material transfer tray 619 is provided with several suckers 620 in a circular array. The suckers 620 preferably adopt vacuum suckers, and the number is at least three. Of course, the suckers 620 can also be replaced with other grabbing components such as electromagnets that can grab the retaining spring 105.

[0074] The material transfer plate 619 is also fixed with two second guide columns 617 by bolts, and the connecting seat 616 is fixed with guide sleeves 622 corresponding to the second guide columns 617 one by one; the second guide columns 617 pass through the corresponding guide sleeves 622 and slide with the guide sleeves 622.

[0075] Taking the first material transfer vehicle 6 picking up material from the second material storage module 4 as an example, the first material transfer vehicle 6 moves above the second material storage module 4, where the gripping component grabs a retaining ring 105. The vehicle then moves to the grinding table 3. The fifth motor 615 activates, causing the third cylinder 618 to become horizontal, with the retaining ring 105 facing the grinding table 3. The first grinder 311, equipped with a first grinding head, then extends, and the first material transfer vehicle 6 drives the retaining ring 105 to move and grind. After the first grinder 311, equipped with the first grinding head, completes its operation, the first grinder 311, equipped with the second grinding head, extends to continue grinding.

[0076] After the two first grinders 311 have completed their operations, the first transfer cart 6 drives the retaining spring 105 to move from the side of the grinding table 3 to the second transfer cart 8. At this time, the third cylinder 618 of the second transfer cart 8 is also horizontal. Then the third cylinder 618 on the second transfer cart 8 and the first transfer cart 6 are both extended to achieve the handover of the retaining spring 105; then the second transfer cart 8 carries the partially polished retaining spring 105 to the grinding table 3, and the second grinder 313 equipped with the second grinding head extends and starts the grinding operation. After the retaining spring 105 is polished, the second transfer cart 8 carries the polished retaining spring 105 to the first blanking machine 2 and places the retaining spring 105 on the first blanking machine 2. After the second transfer cart 8 receives the retaining spring 105, the first transfer cart 6 returns to the second storage module 4 to pick up the material and start the next round of operations.

[0077] When the retaining rings 105 in the second material storage module 4 are completely ground, the grinding process is changed to start from the second material transfer vehicle 8 taking the material and end when the first material transfer vehicle 6 places the retaining rings 105 on the second unloading machine.

[0078] In the present invention, the first blanking machine 2 and the second blanking machine are both belt conveyors.

[0079] Of course, the third cylinder 618 in the present invention can also be omitted. In this case, the material transfer plate 619 is directly installed on the connecting seat 616, and the corresponding strokes of the first material transfer cart 6 and the second material transfer cart 8, as well as the matching racks, etc. need to be adjusted in length.

[0080] All the components of the present invention, such as the cylinder, the motor, the in-position switch, the photoelectric door 503, etc., are electrically connected to the controller and are uniformly controlled by the controller.

[0081] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
