Description

Technical Field

[0001] This utility model relates to a feeding mechanism, and more particularly to an intermittent single feeding mechanism for a stud. Background Technology

[0002] The processing of studs involves multiple steps and equipment, and the corresponding bolts are transferred between these steps. The function of the intermittent single feeding mechanism is to feed in a certain number of studs to be processed, and then release these studs one by one by the feeding mechanism, so that the released studs can enter the next step.

[0003] Existing intermittent single-stud feeding mechanisms generally include: a track for rolling a single stud around an axis, a first baffle, a first cylinder that pushes the first baffle, a second baffle, and a second cylinder that pushes the second baffle. First, the first baffle blocks, the second baffle releases, and the studs sequentially abut against the stack within the track, with the first stud abutting against the first baffle. Next, the second baffle blocks the second-to-first stud. Then, the first baffle releases, and the first stud rolls down the track; then, the first baffle blocks again, the second baffle releases, and all the studs roll one position along the track, returning to the starting state.

[0004] The existing intermittent single feeding mechanism still has the following problems: when the second baffle switches from being released to being blocked, the second stud is against the first stud, and the position where the second baffle blocks the second bolt is generally near the upper outer wall of the second bolt, so the blocking effect is generally not good; using two cylinders to control the first baffle and the second baffle respectively makes debugging more complicated and inconvenient to control or adjust the feeding rhythm of the studs.

Through the first and second slotted pin pairs, the sliding of the sliding part relative to the track is converted into the oscillation of the first and second scissor lifts. A single driving part can drive the first and second scissor lifts to switch between opening and blocking in a predetermined sequence. Each back-and-forth sliding of the sliding part releases one stud. The advantages include: easier debugging and easier control or adjustment of the stud feeding rhythm. Attached Figure Description

[0038] Please see Figure 1 and Figure 2 An intermittent single feeding mechanism for a stud includes: a track 1, a first blocking member 2, a second blocking member 3, a sliding part 4, and a driving part 5.

[0039] Please see Figure 3 The track 1 is inclined in the horizontal direction, meaning that the first side of the track 1 is lower and the second side is higher in the horizontal direction. More specifically, the track 1 may include: two concave strips 11 and two base plates 12. The notches of the two concave strips 11 face each other. The first side of the two base plates 12 is fixedly connected to the bottom surface of one concave strip 11, and the second side of the two base plates 12 is fixedly connected to the bottom surface of the other concave strip 11. While connecting the two concave strips 11 through the two base plates 12, an inlet and outlet are formed between the two base plates 12.

[0040] The length of the stud matches the spacing between the two concave strips 11, the diameter of the stud matches the width of the notch, and the two ends of the stud are respectively inside the notches of the two concave strips 11.

[0041] Please see Figure 2 and Figure 4 The first blocking component 2 includes: a first scissor lift 21 and two first blocking parts 22.

[0042] The first scissor lift 21 is connected to the track 1. More specifically, the first scissor lift 21 can be composed of four first connecting bars 211. Two first connecting bars 211 can be a group, hinged to the outer wall of the same concave bar 11. The end of the connecting bar on the second side of the hinge position is the output end 211c. The two first connecting bars 211 in the same group form two swingable output ends 211c.

[0043] Two first blocking parts 22 are connected to the first scissor lift 21. Specifically, the two ends of one first blocking part 22 are respectively connected to the output ends 211c above the two sets of first connecting bars 211 and are kept above the track 1; the two ends of the other first blocking part 22 are respectively connected to the output ends 211c above the two sets of first connecting bars 211 and are kept below the track 1.

[0044] The first scissor lift 21 has two first blocking parts 22 that move closer to or further away from the guide rail simultaneously. The upper first blocking part 22 enters between the two concave bars 11, and the lower first blocking part 22 enters between the two concave bars 11 and between the two base plates 12.

[0045] The first blocking part 22 can be a blocking block, a blocking rod, a roller, etc.

[0046] Please see Figure 4 and Figure 5 The second blocking member 3 includes a second scissor lift 31 and two second blocking parts 32. The structure of the second blocking member 3 can be the same as that of the first blocking member 2, except that, with the hinge position of the track 1 as the dividing line, the first blocking part 22 is on the second side of the hinge position, and the second blocking part 32 is on the first side of the hinge position.

[0047] In some embodiments, the first blocking part 22 and the second blocking part 32 are preferably rollers. More specifically, the rollers are rotatably connected to an mounting strip 221, which can be fixedly connected to the first connecting strip 211 by screws. The outer wall of the roller has a soft layer, such as a layer of silicone, to protect the external threads of the stud.

[0048] In some embodiments, the hinge positions of the two first connecting strips 211 on the outer wall of the concave strip 11 coincide, and the end of the first connecting strip 211 on the first side of the hinge position is the input end 211d. Both first connecting strips 211 in the same group need to have the input end 211d. Correspondingly, the hinge positions of the two second connecting strips 311 on the outer wall of the concave strip 11 coincide, and the end of the second connecting strip 311 on the second side of the hinge position is the input end 211d. Both second connecting strips 311 in the same group need to have the input end 211d.

[0049] In some embodiments, the two first connecting strips 211 are staggered at their hinge positions on the outer wall of the concave strip 11, and each of the two first connecting strips 211 also has a first gear 211a portion at its hinge position, and the two first gears 211a portions mesh. Correspondingly, the two second connecting strips 311 are also staggered at their hinge positions on the outer wall of the concave strip 11, and each of the two second connecting strips 311 also has a second gear 311a portion at its hinge position, and the two second gears 311a portions mesh.

[0050] Please see Figure 5 Preferably, the hinge positions are staggered, and the two first connecting bars 211 / second connecting bars 311 in the same group can each have only one input end 211d, and the other is driven by the first gear 211a / second gear 311a, so that the sliding part 4 used to drive the first scissor lift 21 and the second scissor lift 31 to swing can be more conveniently set.

[0051] Please see Figure 6 The sliding part 4 is slidably connected to the track 1. The sliding part 4 has a first groove 4a and a second groove 4b. The first groove 4a and the first scissor lift 21 form a first grooved pin pair, that is, the driving end of the first connecting bar 211 is connected to the first pin 211b, and a needle roller bearing can be installed as the first pin 211b. The second groove 4b and the second scissor lift 31 form a second grooved pin pair, that is, the driving end of the second connecting bar 311 is connected to the second pin 311b, and a needle roller bearing can be installed as the second pin 311b.

[0052] The sliding of the sliding part 4 relative to the track 1 is converted into the swinging of the first scissor lift 21 and the second scissor lift 31 through the first and second slotted pin pairs. Accordingly, the sliding direction of the sliding part 4 relative to the track 1 can be along the inclined direction of the track 1 or along a direction perpendicular to the inclined direction of the track 1 in a vertical plane.

[0053] Please see Figure 2 In some embodiments, based on the above-mentioned "the two first connecting strips 211 are staggered at the hinge positions on the outer wall of the concave strip 11, and the two second connecting strips 311 are staggered at the hinge positions on the outer wall of the concave strip 11", the two first connecting strips 211 and the two second connecting strips 311 in the same group are all the lower one with an input end 211d. Correspondingly, the sliding part 4 slides relative to the track 1 in the direction of inclination along the track 1. The sliding connection position of the sliding part 4 is on the bottom surface of the track 1. More specifically, a set of linear rails 4c is provided between the sliding part 4 and the track 1.

[0054] Please see Figure 6More specifically, the sliding part 4 can be rectangular, and the two side plates on both sides of the lateral direction can have bent portions, which are fixedly connected to the mounting slider of the linear guide 4c. The two side plates on both sides of the longitudinal direction can be provided with a first groove 4a and a second groove 4b. Connecting rods 211e can be fixed between the two input ends 211d of the first scissor lift 21 and between the two input ends 211d of the second scissor lift 31. The ends of the connecting rods 211e can extend beyond the input ends 211d, and the extended portions are used for mounting needle roller bearings.

[0055] Please see Figure 6 and Figure 7 In some embodiments, the sliding part 4 includes: a base portion 41 for sliding connection with the track 1, a first connecting portion 42 for mounting a first groove track 4a, and a second connecting portion 43 for mounting a second groove track 4b. At least one of the first connecting portion 42 and the second connecting portion 43 can be adjusted to a fixed connection position on the base portion 41.

[0056] More specifically, the base portion 41 can be rectangular, and the two side plates on both sides can have bent portions, which are fixedly connected to the mounting slider of the linear guide 4c.

[0057] More specifically, the first connecting part 42 can be two plates, each provided with a first groove rail 4a, which are respectively fixedly connected to two side plates on both sides of the longitudinal direction of the base part 41. The second connecting part 43 can be two plates, each provided with a second groove rail 4b, which are respectively fixedly connected to two side plates on both sides of the longitudinal direction of the base part 41.

[0058] More specifically, the first connecting part 42 and the second connecting part 43 are fixedly connected to the base in the following way: the two side plates on both sides of the longitudinal side of the base part 41 have multiple waist-shaped grooves 41a along the inclined direction of the track 1, and screws are threaded through the waist-shaped grooves 41a to the first connecting part 42 / second connecting part 43.

[0059] The relative positions between the first groove rail 4a and the second groove rail 4b can be adjusted so that the first groove rail 4a and the second groove rail 4b can achieve a better correspondence.

[0060] Please see Figure 8 The first track 4a includes, in sequence: a first section 4a1 that makes the first blocking part 22 a blocking part, a second section 4a2 that makes the first blocking part 22 switch from blocking to opening, and a third section 4a3 that makes the first blocking part 22 open.

[0061] The second track 4b includes, in sequence: a fourth section 4b1 that opens the second blocking part 32, a fifth section 4b2 that switches the second blocking part 32 from open to blocked, and a sixth section 4b3 that blocks the second blocking part 32.

[0062] The correspondence between the first groove 4a and the second groove 4b is as follows: the second segment 4a2, the third segment 4a3 and part of the first segment 4a1 correspond to the sixth segment 4b3, that is, the remaining part of the first segment 4a1 corresponds to the fourth segment 4b1 and the fifth segment 4b2.

[0063] Please see Figure 9 Initially, the sliding part 4 is set on the second side of the track 1, the first pin 211b is in the first section 4a1, and the first blocking part 22 is blocking; the second pin 311b is in the fourth section 4b1, and the second blocking part 32 is open. The studs are stacked in sequence in the track 1, and the first stud abuts against the first blocking part 22.

[0064] The sliding part 4 moves from the second side of the track 1 to the first side, the first pin 211b remains in the first section 4a1, and the first blocking part 22 remains in the blocking position; the second pin 311b moves from the fourth section 4b1 through the fifth section 4b2 into the sixth section 4b3, and the second blocking part 32 switches from open to blocking, blocking the first second stud.

[0065] The sliding part 4 enters the first side of the track 1, the first pin 211b moves from the first segment 4a1 through the second segment 4a2 into the third segment 4a3, and the first blocking part 22 switches from blocking to opening; the second pin 311b remains in the sixth segment 4b3, the second blocking part 32 remains blocking, the first stud rolls down, and the second blocking part 32 blocks the second stud to become the new first stud.

[0066] Please see Figure 10 Conversely, the sliding part 4 resets from the first side to the second side of the track 1, the first pin 211b enters the first section 4a1 from the third section 4a3 through the second section 4a2, and the first blocking part 22 switches from open to blocking; the second pin 311b remains in the sixth section 4b3, and the second blocking part 32 remains in blocking.

[0067] The sliding part 4 returns to the first side of the track 1, the first pin 211b is in the first section 4a1, and the first blocking part 22 remains in the blocking position; the second pin 311b moves from the sixth section 4b3 through the fifth section 4b2 into the fourth section 4b1, and the second blocking part 32 switches from blocking to opening, and all studs roll one position along the track 1 and return to the starting state.

[0068] In other words, each back-and-forth movement of the sliding part 4 releases a stud.

[0069] The drive unit 5 is used to move the sliding unit 4.

[0070] Qing Reference Figure 9 , Figure 10 and Figure 11 In some embodiments, the drive unit 5 is a cylinder or a crank-slider mechanism.

[0071] For the cylinder, each extension and retraction of the cylinder causes the sliding part 4 to slide back and forth once. Adjusting the extension and retraction frequency of the cylinder will adjust the frequency of the screw being released.

[0072] More specifically, for the crank-slider mechanism, the crank can be rotatably connected to the track 1 around the longitudinal axis, and the crank is driven to rotate by a motor; the sliding part 4 serves as the slider of the crank-slider mechanism, and a connecting rod is hinged between the crank and the sliding part 4. The motor can be a speed-regulating motor. When the motor drives the crank to rotate one revolution, the sliding part 4 slides back and forth once. Adjusting the motor speed can adjust the frequency of the stud release.
