[0002] The screw grinding tool is a special tooling equipment used for screw grinding. Screw grinding is a common machining process used to manufacture threaded parts such as screws, nuts, and screws.

In actual use, the existing screw grinding tooling is relatively cumbersome to adjust and set up, especially when it is necessary to replace screws of different lengths and diameters.

[0016] The present invention also provides a method for processing the screw processing tool as described above, comprising the following steps:

[0017] S1: multiple screws to be ground are placed on the surface of the loading plate of the slot box. Since the surface of the loading plate is inclined, under the action of the gravity of the screws to be ground, the screws to be ground closest to the installation slot will be under the U-shaped column, and the remaining screws to be ground are restricted due to the blocking effect of the baffle, that is, multiple screws to be ground can be stably placed;

[0018] S2: The first motor starts, driving the first gear to rotate, which is driven by the sprocket chain to drive the first rotating column to rotate. Under the elastic force of the first spring, the multiple first clamping blocks will be stably connected with the second clamping blocks, so that the rotation of the first rotating column can stably drive the worm to rotate, and the worm wheel rotates with the rotation of the worm, thereby driving the third rotating column to rotate. The adjusting column rotates with the rotation of the third rotating column, and the protrusion and the first spiral groove and the second spiral groove produce relative movement, driving the connecting ring and the U-shaped column to move toward the direction close to the placement groove. The transmission gear cooperates with the first rack, and the top block and the positioning block lift the screw to be ground on the surface of the placement groove closest to the installation groove for loading. Since the positioning blocks are inclined, the screw to be ground can be stably placed on the surfaces of the four positioning blocks under the action of its own gravity;

[0019] S3: The rotation of the first gear drives the second gear to rotate, and the rotation of the second gear drives the third gear to rotate. The transmission column rotates with the rotation of the third gear. The rotation of the transmission column can drive the adjustment disk to rotate. The disk rotates with the rotation of the third rotating column. The first arc block can cooperate with the second arc block to drive the rotating disk to rotate. The two connecting columns pull the two L-shaped plates towards each other, and the screw to be ground is brought away from the surface of the positioning block by multiple clamping rods. As the two L-shaped plates continue to approach each other, the two ends of the screw to be ground will respectively contact the conical groove walls on the surfaces of the two adjusting disks for clamping, and then the grinding assembly grinds the screw. After the processing is completed, the first motor drives the first gear to rotate in the opposite direction and returns to the initial state, and the next screw to be ground is ground, and this cycle is repeated.

[0020] Compared with the prior art, the present invention provides a screw processing tool and a processing method thereof, which have the following beneficial effects:

[0021] 1. The screw processing tooling is driven by the first motor to rotate the first gear, which is transmitted through the chain sprocket, the first rotating column, the worm gear and the third rotating column, and then drives the adjusting column to rotate. Relative movement occurs between the protrusion and the first spiral groove and the second spiral groove. The connecting ring, the U-shaped column, the connecting rod and the transmission gear first move in the direction close to the placement groove, and then move in the direction away from the placement groove. In this process, the transmission gear cooperates with the first rack to drive the rotating rod and the connecting rod to rotate, so that the top block and the positioning block can bring the screw to be ground, which is located on the surface of the placement groove closest to the installation groove, away from the placement groove during the rotation process. Since the positioning block is inclined, the screw to be ground can be stably placed on the surface of the positioning block for loading. The stability of loading can be guaranteed for screws of different diameters and lengths to be ground.

[0022] During the relative movement between the protrusion and the first spiral groove, the transmission gear meshes with the first rack, thereby driving the connecting rod and the rotating rod to rotate. The positioning block first contacts the baffle, driving the baffle to rotate, and then the fixed column contacts the baffle, driving the baffle to continue to rotate. Under the action of the gravity of multiple screw rods to be ground placed on the surface of the loading plate, the screw rod to be ground closest to the top block will be pushed between the baffle and the top block, and the baffle will return to its initial state under the action of the torsion spring force, and continue to place and position multiple screw rods to be ground, that is, to ensure that there is subsequent replenishment after each loading is completed, and orderly and automatic loading can be carried out for screw rods to be ground of different diameters and lengths.

[0023] 2. The screw processing tooling has a disc that rotates as the third rotating column rotates, and the first arc block cooperates with the second arc block to drive the rotating disc to rotate. The two connecting columns pull the two L-shaped plates to move towards each other, and multiple clamping rods can bring the screw to be ground away from the surface of the positioning block. The two ends of the screw to be ground are in contact with the conical groove and the surface of the clamping block respectively. As the two L-shaped plates get closer, the second spring is compressed, and the elastic force of the second spring is used to clamp the screw to be ground. The clamping stability of screws to be ground of different diameters and lengths can be guaranteed. When replacing screws of different diameters and lengths for grinding, there is no need to make multiple adjustments, thereby shortening the time required for grinding and improving the grinding efficiency.

The surface of the second rotating column 510 is fixedly connected with a first gear 512. The surface of the side plate 16 located below the second rotating column 510 is fixedly connected with a motor seat 513, and the surface of the motor seat 513 is fixedly connected with a first motor 514. The output shaft of the first motor 514 is fixedly connected with the first gear 512, and the outer side of the first gear 512 is meshedly connected with a second gear 515, and the outer side of the second gear 515 is meshedly connected with a third gear 516. The surface of the side plate 16 located beside the second rotating column 510 is fixedly connected with a connecting plate 517, and the second gear 515 is rotatably connected to the connecting plate 517, and a transmission column 518 is slidably connected inside the third gear 516;

[0043] The outer side of the worm 51 is meshingly connected with a worm wheel 519, and a third rotating column 5110 is fixedly connected to the surface of the worm wheel 519. An adjusting column 5111 is fixedly connected to the lower end of the third rotating column 5110. A first spiral groove 5112, a connecting groove 5113 and a second spiral groove 5114 are provided on the surface of the adjusting column 5111. The first spiral groove 5112 is communicated with the second spiral groove 5114, and the connecting groove 5113 is communicated with the first spiral groove 5112 and the second spiral groove 5114. A protrusion 5115 is installed on the groove wall of the first spiral groove 5112.

[0044] It should be noted that a plurality of screws to be ground of different diameters and lengths are placed on the surface of the blanking plate and the placement groove 14, and are placed and limited by the baffle 417. A screw to be ground is also placed on the wall of the placement groove 14 closest to the mounting groove 13. The first motor 514 is started to drive the first gear 512 to rotate, and then drives the second rotating column 510 to rotate. The chain sprocket 511 drives the first rotating column 54 to rotate, and the first circular block 52, the first clamping block 53, the second circular block 58 and the second clamping block 59 drive the worm 51 to rotate. The worm wheel 519 meshes with the worm 51, and the worm 51 rotates with the worm wheel 519. The second gear 515 is meshed with the first gear 512, and the second gear 515 rotates as the first gear 512 rotates.

The transmission column 518 is slidably connected with the third gear 516, and the transmission column 518 rotates as the third gear 516 rotates, which can drive the clamped screw to be ground to rotate, thereby facilitating the grinding assembly 12 to perform grinding.

[0045] It should be noted that, when the two L-shaped plates 32 are adjusted and moved to clamp and position the screw to be ground, relative movement occurs between the connecting block 315 and the rotating sleeve 316, and the second spring 317 is gradually compressed. The elastic force of the second spring 317 can ensure that the screw to be ground is clamped stably. When the screw to be ground is clamped, the first clamping block 53 and the second clamping block 59 rotate relative to each other, and the T-shaped column 56 and the column groove 55 slide relative to each other. The first spring 57 is further compressed and then restored to its original state, that is, the rotation of the first rotating column 54 no longer drives the worm 51 to rotate, and does not affect the grinding of the screw.

[0046] See also Figure 3 , the initial state of the first spring 57 is a compressed state;

[0047] It should be noted that the reaction force generated by the compression of the first spring 57 acts on the surface of the T-shaped column 56, so that the first clamping block 53 on the surface of the first disk 38 can be stably engaged with the second clamping block 59 on the surface of the second disk 38, so that the rotation of the first rotating column 54 can stably drive the worm 51 to rotate.

[0048] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8The clamping mechanism 3 includes a slider 31 symmetrically slidably connected to the wall of the mounting groove 13, an L-shaped plate 32 is fixedly connected to the surface of the slider 31, a connecting column 33 is rotatably connected to the end of the L-shaped plate 32 away from the slider 31, and a convex column 34 is rotatably connected to the end of the connecting column 33 away from the L-shaped plate 32, and a rotating disk 35 is fixedly connected to the upper ends of the two convex columns 34. A circular hole 36 is opened at the center of the surface of the rotating disk 35, and a first arc block 37 is fixedly connected to the wall of the circular hole 36. There are two first arc blocks 37, and a disk 38 is fixedly connected to the surface of the third rotating column 5110, and a second arc block 39 is fixedly connected to the surface of the disk 38. An adjusting disk 310 is rotatably connected to the end of the L-shaped plate 32 close to the slider 31, and a conical shape is opened in the middle of the surface of the adjusting disk 310 The groove 311 and the surface of the side plate 16 close to the grinding assembly 12 are fixedly connected with a rotating ring 312, and the surface of the rotating ring 312 away from the adjusting disk 310 is fixedly connected with a ring-shaped uniformly distributed clamping rod 313, one of the adjusting disks 310 is fixedly connected to one end of the transmission column 518 close to the L-shaped plate 32, and a clamping block 314 is installed in the other adjusting disk 310, and the surface of the clamping block 314 away from the grinding assembly 12 is symmetrically fixedly connected with a connecting block 315, and the outer side of the connecting block 315 is slidably connected with a rotating sleeve 316, and the inner wall of the rotating sleeve 316 is fixedly connected with a second spring 317, and the other end of the second spring 317 is fixedly connected to the connecting block 315, and the ends of the two rotating sleeves 316 close to the L-shaped plate 32 are fixedly connected to the adjusting disk 310;

[0049] It should be noted that the clamping mechanism 3 can ensure stable clamping of screws to be ground of different diameters and lengths. When replacing screws of different diameters and lengths for grinding, there is no need to make multiple adjustments, thereby shortening the time required for grinding and improving the grinding efficiency.

[0050] Specifically, in the process of the connecting column 33 pulling the two L-shaped plates 32 to move towards each other, the multiple clamping rods 313 will bring the screw to be ground placed on the surface of the positioning block 416 away from the surface of the positioning block 416. As the two L-shaped plates 32 continue to approach each other, the multiple clamping rods 313 can limit the screw to be ground, so that the two ends of the screw to be ground are respectively in contact with the conical groove 311 and the clamping block 314, the clamping block 314 can be separated from the adjusting disk 310, and the connecting block 315 moves with the clamping block 314. The second spring 317 is compressed. The elastic force of the second spring 317 is used to stably clamp the screws of different lengths and diameters to be ground, and then the grinding assembly 12 performs grinding.

[0051] See also Figure 7 and Fig. 9 , the transmission column 518 is a quadrangular column;

[0052] It should be noted that the arrangement of the transmission column 518 can ensure the stability of the transmission, so that the rotation of the third gear 516 can stably drive the transmission column 518 to rotate.

[0053] See also Figure 1 , Figure 2 , Figure 5 , Fig. 9 , Fig.11 and Fig.12 The feeding mechanism 4 includes a connecting ring 41 sleeved on the outside of the adjusting column 5111, the protrusion 5115 is fixedly connected to the inner wall of the connecting ring 41, the surface of the connecting ring 41 is symmetrically fixedly connected with a U-shaped column 42, and the ends of the two U-shaped columns 42 away from the connecting ring 41 are respectively slidably connected with the two vertical grooves 2, and the surface of the U-shaped column 42 is installed with a rotating rod 43 through a torsion spring. The end surface of the rotating rod 43 close to the side plate 16 is provided with a transverse groove 44, and the groove wall of the transverse groove 44 is slidably connected with a movable block 45, and the surface of the movable block 45 is fixedly connected with a reset spring 46 and a connecting rod 47, and the side of the movable block 45 is fixedly connected with a friction block 48, and the friction block 48 is installed in cooperation with the rotating rod 43, and the surface of the friction block 48 is fixed. A slanted block 49 is connected, one end of the connecting rod 47 away from the movable block 45 is rotatably connected to the transmission gear 410 through a one-way bearing, one end of the surface of the connecting rod 47 close to the transmission gear 410 is rotatably connected to a vertical plate 411, the wall of the placement slot 14 is symmetrically provided with slanted slots 412, the vertical plate 411 is slidably connected to the slanted slots 412, the surface of the side plate 16 close to the transmission gear 410 is fixedly connected to a first rack 413, the surface of the side plate 16 above the first rack 413 is fixedly connected to an F-shaped plate 414, the end of the surface of the rotating rod 43 away from the transmission gear 410 is fixedly connected to a top block 415, and the end of the surface of the top block 415 away from the rotating rod 43 is symmetrically provided with a positioning block 416 through a torsion spring;

[0054] It should be noted that the feeding mechanism 4 can ensure the stability of feeding for the screws to be ground of different diameters and lengths, ensure that there is subsequent replenishment after each feeding is completed, and can automatically feed the screws to be ground of different diameters and lengths in an orderly manner;

[0055] Specifically, the worm gear 519 and the worm 51 are driven to drive the third rotating column 5110 to rotate. Initially, the second arc block 39 contacts the surface of one of the first arc blocks 37, and the disk 38 rotates as the third rotating column 5110 rotates. The rotation of the third rotating column 5110 drives the adjusting column 5111 to rotate at the same time, and a relative movement occurs between the protrusion 5115 and the first spiral groove 5112. The connecting ring 41 and the two U-shaped columns 42 all move toward the direction close to the placement groove 14, and the transmission gear 410 meshes with the first rack 413, thereby driving the transmission gear 410 to rotate. Since the transmission gear 410 and the connecting rod 47 are rotationally connected through a one-way bearing, when the transmission gear 410 moves toward the direction close to the inclined groove 412, the rotation of the transmission gear 410 can drive the connecting rod 47 to rotate, but vice versa. A torsion spring is arranged between the rotating rod 43 and the U-shaped column 42. During the rotation of the connecting rod 47 and the rotating rod 43, the torsion spring is deformed. After the transmission gear 410 is separated from the first rack 413, the rotating rod 43 and the connecting rod 47 can be restored to their original state under the elastic force of the torsion spring. The positioning block 416 and the top block 415 rotate with the rotation of the rotating rod 43. During the rotation, the positioning block 416 and the top block 415 bring the screw to be ground, which is located on the surface of the placement groove 14 closest to the installation groove 13, away from the placement groove 14. Since the positioning block 416 is inclined, the screw to be ground can be stably placed on the surface of the positioning block 416. When relative movement occurs between the protrusion 5115 and the second spiral groove 5114, the connecting ring 41 and the U-shaped column 42 move upward as the adjusting column 5111 continues to rotate to load the material. The stability of loading can be guaranteed for screws to be ground of different diameters and lengths.

[0056] When the protrusion 5115 moves to the highest point of the second spiral groove 5114, the second arc block 39 just contacts the surface of the other first arc block 37. As the third rotating column 5110 continues to rotate, the protrusion 5115 will cooperate with the connecting groove 5113, and the rotation of the disc 38 will also drive the rotating disc 35 to rotate. The connecting column 33 pulls the two L-shaped plates 32 to move in a direction close to each other, thereby clamping and positioning the screw to be ground, and then the grinding assembly 12 performs grinding.

[0057] When the projection 5115 moves along the first spiral groove 5112 from the end away from the U-shaped column 42 to the end close to the U-shaped column 42, the transmission gear 410 can mesh with the first rack 413 and then separate. After the transmission gear 410 separates from the first rack 413, the vertical plate 411 can contact the groove wall of the inclined groove 412 and slide relative to each other. The vertical plate 411 moves in the direction away from the side plate 16, and the connecting rod 47 and the transmission gear 410 move in the direction away from the side plate 16 together with the vertical plate 411. The movable block 45 and the transverse groove 44 move relative to each other, the reset spring 46 is compressed, the inclined block 49 and the friction block 48 move together with the movable block 45, and when the protrusion 5115 moves along the surface of the second spiral groove 5114 from the end close to the U-shaped column 42 to the end away from the U-shaped column 42, the connecting ring 41, the U-shaped column 42 and the rotating rod 43 all move in the direction away from the placement groove 14. Due to the friction between the friction block 48 and the surface of the rotating rod 43, under the elastic force of the reset spring 46, the movable block 45, The friction block 48 and the inclined block 49 will slowly move toward the direction close to the vertical plate 411. When the protrusion 5115 moves to the connection point between the second spiral groove 5114 and the connecting groove 5113, the U-shaped column 42, the connecting ring 41 and the rotating rod 43 reach the maximum height after being adjusted, and the inclined block 49 can cooperate with the F-shaped plate 414 to drive the connecting rod 47 to move quickly for a distance until the inclined block 49 is engaged with the F-shaped plate 414, and the first motor 514 drives the first gear 512 to rotate in the opposite direction, that is, the grinding process is completed. When the screw rod is unloading, the protrusion 5115 will move relative to the second spiral groove 5114 and the first spiral groove 5112 in sequence, and the inclined block 49 will move toward the direction close to the placement groove 14 again, and then move away from the placement groove 14. The inclined block 49 can cooperate with the F-shaped plate 414 again to drive the connecting rod 47 to move quickly for a distance. At this time, the transmission gear 410 can mesh with the first rack 413 when it is adjusted to move toward the direction close to the inclined groove 412 next time.

[0058] A baffle 417 is installed on the wall of the mounting hole 15 via a torsion spring, and one end of the top block 415 away from the rotating rod 43 is fixedly connected to a fixing column 418;

[0059] It should be noted that the setting of the baffle 417 can play a blocking role. When the baffle 417 is adjusted and rotated once, the screw to be ground will roll to the position on the surface of the placement groove 14 close to the installation groove 13. The baffle 417 returns to its initial state under the elastic force of the torsion spring, and still places and positions other screws to be ground on the surface of the loading plate 11 and the placement groove 14.

[0060] See also Figure 2 The surface of the top block 415 is located beside the two positioning blocks 416 and is fixedly connected to the limiting protrusions 419;

[0061] It should be noted that the limiting protrusion 419 can limit the positioning block 416, ensuring that the four positioning blocks 416 can be in an inclined state, and can stably place and position the screw to be ground.

[0062] It should be noted that a controller can be installed on the upper surface of the top plate 17, and the first motor 514 and the grinding assembly 12 are electrically connected to the controller, and the controller is controlled by a computer; the grinding assembly 12 is a grinding mechanism used in existing screw grinding processing, which includes a grinding tool, a clamp, a grinding spindle and a guide rail, etc., which will not be repeated here.

[0063] The present invention also provides a method for processing the screw processing tool, and the screw processing method comprises the following steps:

[0064] S1: multiple screws to be ground are placed on the surface of the placement groove 14 and the loading plate 11. Since the surface of the loading plate 11 is inclined, under the action of the gravity of the screws to be ground, the screws to be ground closest to the installation groove 13 will be under the U-shaped column 42, and the remaining screws to be ground are restricted due to the blocking effect of the baffle 417, that is, the multiple screws to be ground can be stably placed;

[0065] S2: The first motor 514 is started, driving the first gear 512 to rotate, which is driven by the sprocket 511 chain to drive the first rotating column 54 to rotate. Under the elastic force of the first spring 57, the plurality of first clamping blocks 53 are stably engaged with the second clamping blocks 59, so that the rotation of the first rotating column 54 can stably drive the worm 51 to rotate, and the worm wheel 519 rotates with the rotation of the worm 51, thereby driving the third rotating column 5110 to rotate, and the adjusting column 5111 rotates with the rotation of the third rotating column 5110, and the protrusion 5115 and the first rotating column 5110 rotate. A relative movement occurs between the first spiral groove 5112 and the second spiral groove 5114, driving the connecting ring 41 and the U-shaped column 42 to move toward the direction close to the placement groove 14. The transmission gear 410 cooperates with the first rack 413, and the top block 415 and the positioning block 416 lift the screw to be ground on the surface of the placement groove 14 closest to the installation groove 13 for loading. Since the positioning blocks 416 are inclined, the screw to be ground can be stably placed on the surface of the four positioning blocks 416 under the action of its own gravity.

[0066] S3: The rotation of the first gear 512 drives the second gear 515 to rotate, and the rotation of the second gear 515 drives the third gear 516 to rotate. The transmission column 518 rotates with the rotation of the third gear 516. The rotation of the transmission column 518 can drive the adjustment disk 310 to rotate, and the disk 38 rotates with the rotation of the third rotating column 5110. The first arc block 37 can cooperate with the second arc block 39 to drive the rotating disk 35 to rotate. The two connecting columns 33 pull the two L-shaped plates 32 to move in a direction close to each other, and the multiple clamping rods 313 bring the screw to be ground away from the surface of the positioning block 416. As the two L-shaped plates 32 continue to approach each other, the two ends of the screw to be ground will respectively contact the groove walls of the conical grooves 311 on the surfaces of the two adjusting disks 310 for clamping, and then the grinding assembly 12 grinds the screw. After the processing is completed, the first motor 514 drives the first gear 512 to rotate in the opposite direction to restore to the initial state, and the next screw to be ground is ground, and this cycle is repeated.
