Description

Technical Field

[0003] Chinese invention patent publication number CN117086383B discloses a stud bolt processing device, comprising a workbench, a mounting frame fixedly connected to its top, a cutting mechanism disposed within the mounting frame, and a length-fixing mechanism disposed at the top of the workbench. The length-fixing mechanism comprises a support plate, a length-fixing assembly, and an elastic pusher assembly. The support plate is fixedly connected to the top of the workbench, a length-fixing slot is defined at the top of the workbench, and the length-fixing assembly is located within the positioning slot. The top of the workbench is provided with a plurality of elastic slots equidistantly defined at the top, and the elastic pusher assembly is located within the elastic slots. The invention utilizes a coordinated arrangement of the support plate, the length-fixing assembly, and the elastic pusher assembly. The length-fixing assembly can be used to fix the length of each cut raw material, facilitating the processing of stud bolts of different sizes. Furthermore, the elastic pusher assembly cooperates with the support plate to simultaneously cut multiple raw materials, and can also handle raw materials of different lengths, thereby improving the efficiency of stud bolt processing.

[0040] The present invention can position a raw material through the cooperation of a driving component 34, a front positioning component 32 and a rear positioning component 33, and is suitable for raw materials of different diameters. The present invention also retains the fixed length component 12 and the cutting mechanism 14. The fixed length component 12 and the cutting mechanism 14 have the same structure as the fixed length component and the cutting mechanism in the double-headed bolt processing equipment of CN117086383B.

[0041] When in use, first start the driving component 34, and drive the front positioning component 32 and the rear positioning component 33 to work synchronously through the driving component 34. The rear positioning component 33 includes a rotating seat 331, a slide 332 and a turntable 333. The rotating seat 331 and the slide 332 are each provided with four. A synchronous slider 334 is slidably provided on the slide 332. A roller 3341 is provided for rotating the head end of the synchronous slider 334. A linkage column 3342 is provided on the outer wall of the synchronous slider 334. A second through-hole 3331 is provided in the middle of the turntable 333. Four through-holes 3333 are provided around the turntable 333. The arc grooves 3332 are distributed at equal angles and slideably cooperate with the linkage column 3342, and the four swivel seats 331 are arranged at equal angles around the circumference of the first through-hole 311 on the rear side wall of the support block 31. The slide seat 332 is located between two adjacent swivel seats 331. The turntable 333 is rotatably arranged on the four swivel seats 331. The first through-hole 311 and the second through-hole 3331 are coaxial. The front positioning assembly 32 and the rear positioning assembly 33 have the same structure. The turntable 333 on the front positioning assembly 32 and the turntable 333 on the rear positioning assembly 33 are both connected to the drive assembly 34 in transmission.

[0042] The driving assembly 34 includes a first motor 341, a synchronous shaft 342 and an arc-shaped rack 343. A driving gear 3411 is installed on the output end of the first motor 341. There are two synchronous shafts 342 and two arc-shaped racks 343. One end of the synchronous shaft 342 is provided with a driven gear 3421, and the other end of the synchronous shaft 342 is provided with a worm gear 3422. The first motor 341 is vertically fixed to the top of the support frame 312. Three side walls of the support block 31 are provided along the front and rear sides thereof. The synchronous rotating seats 313 are arranged in sequence in the height direction, and the synchronous rotating shaft 342 is rotatably set on the three synchronous rotating seats 313 located on the same side. The driving gear 3411 is located between the two driven gears 3421, and the two driven gears 3421 are both engaged with the driving gear 3411. The two arc-shaped racks 343 are respectively arranged on the turntable 333 of the front positioning assembly 32 and the turntable 333 of the rear positioning assembly 33, and the two arc-shaped racks 343 are respectively engaged with the two worm gears 3422.

[0043] The first motor 341 drives the driving gear 3411 to rotate, and the driving gear 3411 drives the two driven gears 3421 to rotate synchronously. The driven gear 3421 drives the synchronous rotating shaft 342 to rotate synchronously. The synchronous rotating shaft 342 drives the worm gear 3422 to rotate, and the worm gear 3422 drives the arc rack 343 to rotate. The arc rack 343 drives the turntable 333 to rotate on the four rotating seats 331. The turntable 333 drives the linkage column 3342 to move in the arc groove 3332. The linkage column 3342 drives the synchronous slider 334 to slide on the slide 332, and the roller 3341 also slides synchronously with the synchronous slider 334. After that, the roller 3341 can abut against the outer wall of the raw material. The four rollers 3341 on the front positioning assembly 32 and the four rollers 3341 on the rear positioning assembly 33 can position two points of the raw material. The raw material will not be offset and the forward and backward movement of the raw material will not be hindered.

[0044] Furthermore, an L-shaped protective plate 314 is provided on the front side of the support block 31. A plurality of third perforations are provided on the L-shaped protective plate 314 for the raw materials to pass through. The third perforations are coaxial with the first perforations 311. The front positioning component 32 is protected by the L-shaped protective plate 314 to prevent the cutting mechanism 14 from accidentally touching the front positioning component 32.

[0045] Then operate the fixed length component 12 to work, and then selectively adjust the elastic pushing component 2 according to the total length of the raw material. The elastic pushing component 2 includes at least one connecting rod 21 and several elastic pushing components. The connecting rod 21 is provided with at least two threaded holes 211. The elastic pushing component includes a tension spring 22, a push rod 23 and a pushing plate 24. The outer wall of the tail end of the push rod 23 is provided with an external thread and a first nut 231 that cooperates with the external thread. The push rod 23 is provided with a rectangular plug block 232. The front outer wall of the pushing plate 24 is provided with a slot 241 that is plugged into the rectangular plug block 232. The groove wall of the slot 241 is provided with a first nut for the push rod 23 to pass through. Four through-holes, an insertion frame 25 that is plugged into and cooperates with the connecting rod 21 is provided on the rear outer wall of the pushing plate 24, a screw sleeve 251 is provided on the rear side wall of the insertion frame 25, an adjusting screw 252 is screwed into the screw sleeve 251, and the adjusting screw 252 is screwed into and cooperates with the threaded hole 211, guide sliders are provided on both sides of the bottom end of the pushing plate 24, and a plurality of elastic grooves 15 are opened on the top of the workbench 1, and guide grooves that cooperate with the guide sliders are provided on both side walls of the elastic groove 15. The tension spring 22 is arranged in the elastic groove 15, and the two ends of the tension spring 22 are fixedly connected to the front end wall of the elastic groove 15 and the pushing plate 24 respectively, and the push rod 23 is coaxial with the first through-hole 311.

[0046] By inserting the connecting rod 21 into the insertion frame 25, it can be selectively inserted into other insertion frames 25 according to the total length of all raw materials, and then tightening the corresponding adjusting screw 252. The adjusting screw 252 can enter the threaded hole 211, and then the connecting rod 21 can be fixed to prevent the pushing plate 24 from being offset due to rapid movement, or even accidentally detaching from the insertion frame 25. All pushing plates 24 can be selectively connected together. After the cutting mechanism 14 completes a cutting operation, the tension spring 22 can pull the pushing plate 24 to move, and the pushing plate 24 can drive the push rod 23 to move. The push rod 23 abuts against one end of the raw material and drives the raw material to move synchronously. Finally, the push rod 23 can be inserted into the first through-hole 311 and the second through-hole 3331. This can prevent the tail of the raw material from being stranded on the front positioning component 32 and the rear positioning component 33. The push rod 23 is also easy to disassemble and easy to maintain.

[0047] Since the length of the raw material tailings often does not reach the length of the raw material after cutting, that is, the raw material tailings do not meet the requirements of processing the corresponding model of stud bolts, it will cause waste if the raw material tailings are directly discarded. In addition, the existing technology is to mix the raw material tailings directly into the cut raw material, and workers need to spend time picking out these raw material tailings, which invisibly increases the workload. Therefore, a screening mechanism 5 is set to screen out the raw material tailings and the cut raw material.

[0048] The screening mechanism 5 includes a screening cylinder 51, a second motor 52 and three adjustment components 53 for changing the size of the discharge port 43. A number of concave placement grooves 511 distributed at equal angles along its circumference are provided on the outer wall of the screening cylinder 51. The screening cylinder 51 is rotatably arranged in the screening cavity 42, and the outer wall of the screening cylinder 51 is in contact with the inner wall of the screening cavity 42. The second motor 52 is arranged on one side outer wall of the discharge frame 4. The screening cylinder 51 is fixedly connected to the output end of the second motor 52. The three discharge ports 43 are distributed at equal angles along the rotation direction of the screening cylinder 51, wherein the two discharge ports 43 are respectively provided with a first discharge channel 431 and a second discharge channel 432. The length of the first discharge channel 431 is greater than the length of the second discharge channel 432. The three adjustment components 53 are arranged on the discharge frame 4, and an auxiliary component 54 for pushing the raw material in the concave placement groove 511 is provided on the other side outer wall of the discharge frame 4.

[0049] The cut raw materials can fall into the feed trough 41, and then roll along the guide slope 411 to the discharge port 412. At the same time, the second motor 52 drives the screening cylinder 51 to rotate intermittently. When an inner concave placement groove 511 is docked with the discharge port 412, a cut raw material can enter the inner concave placement groove 511. After that, all the cut raw materials and all the tails of the raw materials can enter the inner concave placement groove 511 one after another. The screening cylinder 51 drives the cut raw materials or the tail ends of the raw materials to rotate synchronously.

[0050] Since the cut raw materials may be offset when falling into the concave placement groove 511, this will cause the cut raw materials to often be unable to be discharged from the corresponding discharge port 43. The auxiliary component 54 can adjust the position of the cut raw materials in the concave placement groove 511. The auxiliary component 54 includes a suspension 541, and a horizontal push screw slide 542 is installed on the suspension 541. A synchronous slide 543 is provided on the horizontal push screw slide 542. Two abutment rods 544 distributed at equal angles along the rotation direction of the screening cylinder 51 are installed on the synchronous slide 543. The other side wall of the discharge frame 4 is provided with two through holes 44 for the abutment rods 544 to pass through, and the suspension 541 is fixedly connected to the other side wall of the discharge frame 4.

[0051] The synchronous slide 543 is driven to move by the horizontal push screw slide 542, and the synchronous slide 543 drives the two abutment rods 544 to move synchronously, and the abutment rod 544 can enter the through hole 44, and then the abutment rod 544 can enter the screening chamber 42, and then the abutment rod 544 can be correspondingly inserted into an inner concave placement groove 511, and then the abutment rod 544 can abut on the cut raw material, and make one end of the cut raw material close to the inner wall of one side of the screening chamber 42, thereby realizing the position adjustment of the cut raw material. Of course, the tailings of the raw material are also adjusted by this operation. After the adjustment is completed, the horizontal push screw slide 542 drives the synchronous slide 543 to move in the opposite direction to perform the reset operation, and the cut raw material or the tailings of the raw material continue to rotate with the screening cylinder 51, and then the cut raw material and the tailings of the raw material can be discharged from the corresponding discharge port 43.

[0052] The width of the first discharge port 43 along the rotation direction of the screening cylinder 51 is greater than the width of the second discharge port 43 and the width of the third discharge port 43. The width of the third discharge port 43 is greater than the width of the second discharge port. The lengths of the three discharge ports 43 are the same. The first discharge port 43 is used to discharge the tailings of the raw materials, the second discharge port 43 is used to discharge the cut raw materials with a smaller diameter, and the third discharge port 43 is used to discharge the cut raw materials with a larger diameter, thereby realizing the simultaneous screening of two cut raw materials with different diameters, thereby improving applicability and flexibility.

[0053] The size of the corresponding discharge port 43 can be adjusted by adjusting the component 53. The adjusting component 53 includes a transverse arc frame 531, a side opening 5311 is provided on one side of the transverse arc frame 531, a bottom opening 5312 is provided on the bottom of the transverse arc frame 531, a pull rod 533 is provided on the other side of the transverse arc frame 531, an arc inner baffle 532 is provided in the transverse arc frame 531, and a sliding arc inner baffle 532 is provided on the inner wall of one side of the discharge port 43. In conjunction with the first arc-shaped slide groove, three second arc-shaped slide grooves 45 that slide with the arc-shaped inner baffle 532 and three locking parts 55 for locking the arc-shaped inner baffle 532 are provided on one side wall of the discharge frame 4, and an arc-shaped hanging plate 56 is provided on the other side wall of the discharge frame 4. Three horizontal slide grooves 561 that slide with the horizontal moving arc frame 531 are opened in the arc-shaped hanging plate 56, and three positioning parts 57 for positioning the pulling rod 533 are provided on the arc-shaped hanging plate 56.

[0054] The locking piece 55 includes a locking screw 551 and a locking arc plate 552. There are two locking screws 551. A second nut 553 is screwed on the locking screw 551. The locking arc plate 552 is provided with a movable strip groove 554 for the locking screw 551 to move. The two locking screws 551 are fixedly connected to the outer wall of one end of the arc-shaped inner baffle 532 at intervals, and the locking arc plate 552 is fixedly connected to the outer wall of one side of the discharge frame 4.
