Description

Technical Field

[0001] The present invention relates to the technical field related to bolt processing, and specifically relates to a double-headed bolt processing device. Background Art

[0002] Double-headed bolts are closely related to human life. During the production process of double-headed bolts, raw materials are usually cut into segments and then further processed into double-headed bolts.

[0003] A Chinese invention patent with the publication number CN117086383B discloses a double-headed bolt processing device, including a workbench, the top of which is fixedly connected with a mounting frame. A cutting mechanism is arranged inside the mounting frame, and a length-determining mechanism is arranged on the top of the workbench. The length-determining mechanism includes a support plate, a length-determining component and an elastic pushing component. The support plate is fixedly connected to the top of the workbench, and a length-determining groove is opened on the top of the workbench. The length-determining component is located inside the positioning groove, and a plurality of elastic grooves are equidistantly opened on the top of the workbench. The elastic pushing component is located inside the elastic groove. This invention uses the setting method of the cooperation of the support plate, the length-determining component and the elastic pushing component. The length-determining component can perform length-determining processing on the raw materials cut each time, which is convenient for processing double-headed bolts of different sizes. Moreover, the elastic pushing component and the support plate cooperate with each other, and multiple raw materials can be cut and processed at the same time, and raw materials with different lengths can also be used, which improves the processing efficiency of double-headed bolts.

[0023] When in use, the driving component 34 is first started, and the front positioning component 32 and the rear positioning component 33 are driven by the driving component 34 to work synchronously. The rear positioning component 33 includes a rotating seat 331, a sliding seat 332 and a rotating disk 333. The rotating seat 331 and the sliding seat 332 are each provided with four. A synchronous slider 334 is slidably provided on the sliding seat 332. A roller 3341 is rotatably provided at 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 rotating disk 333.

[0024] The driving assembly 34 includes a first motor 341, a synchronous rotating 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 rotating shafts 342 and two arc-shaped racks 343. One end of the synchronous rotating shaft 342 is provided with a driven gear 3421, and the other end of the synchronous rotating shaft 342 is provided with a worm gear 3422. The first motor 341 is vertically fixed on the top of the support frame 312. Three synchronous rotating seats 313 are arranged on the front and rear side walls of the support block 31 in sequence along its height direction. The synchronous rotating shaft 342 is rotatably arranged on the three synchronous rotating seats 313 on the same side. The driving gear 3411 is located between the two driven gears 3421, and both of the two driven gears 3421 are engaged with the driving gear 3411. The two arc-shaped racks 343 are respectively arranged on the turntables 333 of the front positioning assembly 32 and the rear positioning assembly 33, and the two arc-shaped racks 343 are respectively engaged with the two worm gears 3422.

[0025] The first motor 341 drives the driving gear 3411 to rotate. 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. The worm gear 3422 drives the arc-shaped rack 343 to rotate. The arc-shaped 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-shaped groove 3332. The linkage column 3342 drives the synchronous slider 334 to slide on the sliding seat 332. The roller 3341 also slides synchronously with the synchronous slider 334. Then 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, and the raw material will not shift, and the forward and backward movement of the raw material will not be hindered.

[0026] Furthermore, an L-shaped protection plate 314 is provided on the front side of the support block 31. A plurality of third through holes for the raw material to pass through are formed in the L-shaped protection plate 314. The third through holes are coaxial with the first through hole 311. The front positioning assembly 32 is protected by the L-shaped protection plate 314 to prevent the cutting mechanism 14 from accidentally touching the front positioning assembly 32.

[0027] Subsequently, the fixed-length component 12 operates, and then the elastic pushing component 2 is selectively adjusted according to the total length of the raw material. The elastic pushing component 2 includes at least one connecting plug rod 21 and several elastic pushing components. At least two threaded holes 211 are formed in the connecting plug rod 21. The elastic pushing component includes a tension spring 22, a push rod 23, and a push plate 24. An external thread and a first nut 231 matching the external thread are provided on the outer wall of the tail end of the push rod 23. A rectangular plug 232 is provided on the push rod 23. A slot 241 inserted and matched with the rectangular plug 232 is formed on the front side outer wall of the push plate 24. A fourth through hole for the push rod 23 to pass through is formed on the wall of the slot 241. An insertion frame 25 inserted and matched with the connecting plug rod 21 is provided on the rear side outer wall of the push plate 24. A screw sleeve 251 is provided on the rear side wall of the insertion frame 25. An adjusting screw 252 is screwed inside the screw sleeve 251. The adjusting screw 252 is screwed and matched with the threaded hole 211. Guide sliders are provided on both sides of the bottom end of the push plate 24. A plurality of elastic grooves 15 are formed on the top of the workbench 1. Guide grooves matched with the guide sliders are provided on both side walls of the elastic grooves 15. The tension spring 22 is arranged in the elastic groove 15, and both ends of the tension spring 22 are fixedly connected with the front end wall of the elastic groove 15 and the push plate 24 respectively. The push rod 23 is coaxial with the first through hole 311.

[0028] Insert the connecting plug rod 21 into the insertion frame 25, and selectively insert it into other insertion frames 25 according to the total length of all raw materials. Then tighten the corresponding adjusting screw 252. The adjusting screw 252 can enter into the threaded hole 211. After that, the connecting plug rod 21 can be fixed, avoiding the phenomenon that the connecting plug rod 21 is displaced due to the rapid movement of the push plate 24 or even accidentally separated from the insertion frame 25. All push plates 24 can be selectively connected together. After the cutting mechanism 14 completes a cutting operation, the tension spring 22 can pull the push plate 24 to move. The push 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. In this way, the tail material of the raw material can be prevented from staying on the front positioning component 32 and the rear positioning component 33. The push rod 23 is also convenient to disassemble and is easy to maintain.

[0029] Since the length of the tail material of the raw material often fails to reach the length of the cut raw material, that is, the tail material of the raw material does not meet the requirements for processing double-headed bolts of the corresponding model. If the tail material of the raw material is directly discarded, it will cause waste. Moreover, in the prior art, the tail material of the raw material is directly mixed into the cut raw material, and workers still need to spend time picking out the tail material of these raw materials, which invisibly increases the workload. Therefore, a screening mechanism 5 is provided to screen out the tail material of the raw material and the cut raw material.

[0030] The screening mechanism 5 includes a screening cylinder body 51, a second motor 52, and three adjusting components 53 for changing the size of the discharge port 43. A number of concave placement grooves 511 are provided on the outer wall of the screening cylinder body 51 at equal angular intervals along its circumference. The screening cylinder body 51 is rotatably arranged in the screening cavity 42, and the outer wall of the screening cylinder body 51 is in contact with the inner wall of the screening cavity 42. The second motor 52 is arranged on the outer wall of one side of the discharge frame 4, and the screening cylinder body 51 is fixedly connected to the output end of the second motor 52. The three discharge ports 43 are distributed at equal angular intervals along the rotation direction of the screening cylinder body 51. A first discharge channel 431 and a second discharge channel 432 are respectively provided at two of the discharge ports 43. The length of the first discharge channel 431 is greater than that of the second discharge channel 432. The three adjusting components 53 are arranged on the discharge frame 4, and an auxiliary component 54 for pushing the raw materials in the concave placement grooves 511 is arranged on the outer wall of the other side of the discharge frame 4.

[0031] The cut raw materials can fall into the feed groove 41, and then roll along the guiding inclined surface 411 towards the discharge port 412. At the same time, the second motor 52 drives the screening cylinder body 51 to rotate intermittently. When a concave placement groove 511 is aligned with the discharge port 412, a cut raw material can enter into this concave placement groove 511. After that, all the cut raw materials and the tail materials of all the raw materials can successively enter into the concave placement grooves 511, and the screening cylinder body 51 drives the cut raw materials or the tails of the raw materials to rotate synchronously.

[0032] Since the cut raw materials may shift when falling into the concave placement grooves 511, this may cause the cut raw materials to often fail to be discharged from the corresponding discharge ports 43. The auxiliary component 54 can adjust the positions of the cut raw materials located in the concave placement grooves 511. The auxiliary component 54 includes a suspension bracket 541. A transverse push screw slide 542 is installed on the suspension bracket 541. A synchronous slide 543 is provided on the transverse push screw slide 542. Two abutting rods 544 are installed on the synchronous slide 543 and are distributed at equal angular intervals along the rotation direction of the screening cylinder body 51. Two through holes 44 for the abutting rods 544 to pass through are provided on the other side wall of the discharge frame 4. The suspension bracket 541 is fixedly connected to the other side wall of the discharge frame 4.

[0033] The transverse push screw slide 542 drives the synchronous slide 543 to move. The synchronous slide 543 drives the two abutting rods 544 to move synchronously. The abutting rods 544 can enter the through hole 44, and then the abutting rods 544 can enter the screening chamber 42. After that, the abutting rods 544 can be correspondingly inserted into an inner concave placement groove 511. Subsequently, the abutting rods 544 can abut against the cut raw material, and one end of the cut raw material can be made to be close to the inner wall on one side of the screening chamber 42, thereby realizing the position adjustment of the cut raw material. Of course, the tail material of the raw material is also position-adjusted through this operation. After the adjustment is completed, the transverse push screw slide 542 drives the synchronous slide 543 to move in the reverse direction for resetting. The cut raw material or the tail material of the raw material continues to rotate with the screening cylinder 51, and then the cut raw material and the tail material of the raw material can be discharged from the corresponding discharge ports 43.

[0034] The width of the first discharge port 43 along the rotation direction of the screening cylinder 51 is greater than the widths of the second discharge port 43 and 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 for discharging the tail material of the raw material, the second discharge port 43 is for discharging the cut raw material with a smaller diameter, and the third discharge port 43 is for discharging the cut raw material with a larger diameter, thereby realizing the synchronous screening of the cut raw materials with two different diameters and improving the applicability and flexibility.

[0035] The size of the corresponding discharge port 43 can be adjusted through the adjusting component 53. The adjusting component 53 includes a transverse moving arc frame 531. A side opening 5311 is formed on one side of the transverse moving arc frame 531, and a bottom opening 5312 is formed on the bottom of the transverse moving arc frame 531. A pull rod 533 is provided on the other side of the transverse moving arc frame 531. An arc-shaped inner baffle 532 is slidably arranged in the transverse moving arc frame 531.
