Description

Technical Field

[0001] This utility model relates to the field of lead screw manufacturing, and in particular to a clockwise adjusting feeding device. Background Technology

[0002] When processing lead screw blanks, the blanks are poured into a feed box during loading. The blanks then roll into a V-groove in front of the thread rolling machine. A cylinder pushes the blanks from the V-groove into the machine. During loading, the end of the blank to be rolled must face the machine. However, because some lead screw blanks are small in diameter and short in length, their orientation may change after being poured into the feed box, making it impossible to guarantee that the end to be rolled on every blank faces the machine. If the end to be rolled is not facing the machine during loading, the non-rolled end will be pushed into the machine, leading to a production accident. Manual loading is inefficient and cannot guarantee worker safety.

[0003] Therefore, the purpose of this utility model is to provide a clockwise adjusting feeding device that can automatically feed small diameter and short length lead screw blanks into the thread rolling machine, and can rotate and straighten the lead screw blanks during the feeding process. Utility Model Content

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a clockwise adjusting feeding device, installed before the feed inlet of a thread rolling machine, comprising:

[0005] A sensing and rotating assembly, comprising, from top to bottom, a sensing mechanism and a rotating mechanism, with a first station, a second station, and a third station arranged sequentially from top to bottom between the sensing mechanism and the rotating mechanism. The rotating mechanism includes a fixture, a rotating device, and a lifting device connected sequentially from top to bottom. The sensing mechanism is used to detect whether the lead screw blank at the upper end of the fixture is aligned. The rotating device drives the fixture to rotate. The upper end of the fixture is provided with a first tooth spaced apart. The lifting device drives the first tooth to reciprocate between the third station and the first station.

[0006] The feeding mechanism includes a feeding box, a first moving device, and a carrier plate. The sensing mechanism is disposed on the outer wall of the feeding box. The feeding box has a discharge port at its lower end. The carrier plate is slidably disposed below the discharge port. The second station, the carrier plate, and the first moving device are arranged sequentially along the sliding direction of the carrier plate. The end of the carrier plate near the second station is provided with a second tooth at intervals. The first moving device drives the second tooth to move from below the discharge port to the second station. The first tooth and the second tooth are staggered. The upper surfaces of the first tooth and the second tooth are provided with through grooves for accommodating the lead screw blank.

[0007] During feeding, the carrier plate moves from the lower end of the loading box to the upper part of the fixture. During this process, a lead screw blank will pass through the discharge port and fall into the slot of the second tooth at the end of the carrier plate. The second tooth at the end of the carrier plate will move above the first tooth of the fixture, and the first and second teeth will interlock. When the fixture rises, the first tooth at the upper end of the fixture will pass through the gap between the adjacent second teeth and lift the lead screw blank on the second tooth, transferring the lead screw blank from the carrier plate to the upper end of the fixture. After the carrier plate resets, the fixture can rotate.

[0008] The sensing mechanism detects whether the lead screw blank is placed backwards by sensing both ends of the lead screw. If the lead screw blank is placed backwards, the rotating device controls the fixture to rotate 180° to rotate and straighten the lead screw blank, so that the end of the lead screw blank to be threaded is aligned with the thread rolling machine. The lifting device of the rotating mechanism lifts the rotating device and fixture to the first position, so that the lead screw blank and the feed port of the thread rolling machine are at the same height.

[0009] Preferably, the clockwise adjusting feeding device further includes:

[0010] A feeding device is installed in front of the feed inlet of the thread rolling machine. The feeding device drives the lead screw blank to move linearly to the thread rolling machine.

[0011] The second pushing mechanism drives the lead screw blank to move linearly to one end of the feeding device near the inlet;

[0012] The first pushing mechanism, the first station, the second pushing mechanism, and the thread rolling machine are sequentially distributed along a horizontal straight line. The first pushing mechanism drives the lead screw blank from the first station to the second pushing mechanism. After the lifting device of the rotating mechanism lifts the rotating device and the fixture to the first station, the first pushing mechanism pushes the lead screw blank at the upper end of the fixture through the through groove of the first tooth into the second pushing mechanism. During the process of moving the lead screw blank to the second pushing mechanism, the direction of movement of the lead screw blank is parallel to the center line of the through groove.

[0013] After the lead screw blank enters the second pushing mechanism, the second pushing mechanism moves the lead screw blank between the feeding device and the inlet. During the movement, the direction of movement of the lead screw blank is perpendicular to the center line of the through groove, and the center line of the lead screw blank and the center line of the through groove remain parallel to each other. Finally, the feeding device pushes the lead screw blank into the inlet of the thread rolling machine for thread rolling.

[0014] Preferably, the feeding mechanism, the second pushing mechanism, the feeding device, and the first pushing mechanism are arranged sequentially around the first workstation.

[0015] Preferably, the feeding device includes a first slide, a feeding plate, a push rod, a first linear moving element and a second linear moving element. The first slide is connected to the first linear moving element, the push rod is connected to the second linear moving element, the feeding plate and the second linear moving element are respectively disposed at both ends of the first slide, a feeding groove is provided on the upper surface of the feeding plate, and the lower end of the push rod is slidably disposed inside the feeding groove.

[0016] Preferably, the second pushing mechanism includes a second moving device and a second pushing block connected to each other. A receiving groove is formed on the surface of the second pushing block near the first station. The center line of the receiving groove, the center line of the through groove, and the center line of the inlet are parallel to each other. The moving direction of the second pushing block is perpendicular to the center line of the receiving groove.

[0017] Preferably, the first pushing mechanism includes a third moving device and a first pushing block connected to each other. The first pushing block has a protrusion at one end near the first station that engages with the clearance of the through groove. The protrusion is positioned above the through groove. The protrusion is used to push the lead screw blank to slide along the through groove of the first tooth.

[0018] Preferably, the feeding box includes a box body, a feeding channel, a bidirectional lead screw, and guide plates. The feeding channel is inclinedly disposed inside the box body, and the bidirectional lead screw is rotatably disposed inside the feeding channel. Two guide plates are symmetrically disposed and slidably disposed inside the feeding channel, and the two guide plates are threadedly connected to both ends of the bidirectional lead screw. When the bidirectional lead screw rotates, the two guide plates will move closer to each other or further away from each other, which can change the distance between the two guide plates and can accommodate lead screw blanks of various lengths.

[0019] Preferably, the sensing mechanism includes a fourth moving device, a bracket, and a sensor. The sensor is disposed at both ends of the bracket. The fourth moving device is connected to the bracket from top to bottom, and the fourth moving device drives the bracket to move up and down. The fourth moving device is used to drive the bracket and sensor to move up and down. The fourth moving device drives the bracket and sensor to descend directly above the lead screw blank to facilitate the detection of the lead screw blank.

[0020] Preferably, the first moving device, the second moving device, the third moving device, the fourth moving device, the first linear moving element, and the second linear moving element are all any one of a cylinder, a hydraulic cylinder, and a linear module.

[0021] Preferably, the lower end of the push rod is provided with a vacuum suction hole, and the vacuum suction hole is connected to a vacuum generator through a pipe.

[0022] The clockwise adjusting feeding device also includes a worktable and a support frame. The thread rolling machine is detachably mounted on the upper surface of the worktable, and the support frame is detachably mounted on one end of the worktable. The feeding device, the second pushing mechanism, the first pushing mechanism, the rotating mechanism, and the feeding mechanism are all mounted on the support frame.

[0023] The support frame has a stepped groove at one end near the feed inlet of the thread rolling machine. A discharge device, which can be a material channel or a product receiving box, is located inside the stepped groove. After the thread rolling of the lead screw blank is completed, the vacuum generator is activated. The vacuum generator sucks the end of the lead screw blank away from the thread rolling machine through the vacuum suction hole. Then, the feeding device resets, pulling the lead screw blank out of the thread rolling machine. When the lead screw blank passes above the discharge device, the vacuum generator is turned off, and the push rod pushes the lead screw blank, causing it to fall into the discharge device.

[0024] The beneficial effects of this invention are as follows: The sensing mechanism detects whether the lead screw blank is placed in reverse by sensing both ends of the lead screw. If the lead screw blank is placed in reverse, the rotating device controls the fixture to rotate 180° to rotate and straighten the lead screw blank, so that the end of the lead screw blank to be threaded is aligned with the thread rolling machine. The lifting device of the rotating mechanism lifts the rotating device and the fixture to the first working position, so that the lead screw blank and the feed port of the thread rolling machine are at the same height, ensuring that the product is coaxial with the feed port when it is fed to the thread rolling machine.

[0025] Automatic product orientation recognition ensures accurate feeding of products to the thread rolling machine, enabling automated feeding of threaded products. This improves product quality and output, reduces processing costs, and enhances the company's core competitiveness. It guarantees accurate product orientation when feeding into the thread rolling machine and ensures timely product removal after each die clamping and rolling cycle. Attached Figure Description

Detailed Implementation

[0037] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0038] It should be noted that, in this utility model, unless otherwise stated, when an element is referred to as "fixed to" or "set on" another element, it may be directly on the other element or may have an intervening element present at the same time.

[0039] like Figures 1-9 As shown in the figure, an embodiment of the present invention provides a clockwise adjusting feeding device, which is installed in front of the feed inlet of the thread rolling machine 2, and includes:

[0040] The feeding device 9 is located in front of the feed inlet of the thread rolling machine 2. The feeding device 9 drives the screw blank to move linearly to the thread rolling machine 2.

[0041] The second pushing mechanism 8 drives the lead screw blank to move linearly to one end of the feeding device 9 near the inlet;

[0042] The first pushing mechanism 7, the first station, the second pushing mechanism 8 and the thread rolling machine 2 are distributed in sequence along a horizontal straight line. The first pushing mechanism 7 drives the screw blank to move from the first station to the second pushing mechanism 8.

[0043] like Figures 5-6 As shown, the sensing and rotating assembly includes, from top to bottom, a sensing mechanism 6 and a rotating mechanism 5. Between the sensing mechanism 6 and the rotating mechanism 5, from top to bottom, are a first station, a second station, and a third station. The rotating mechanism 5 includes, from top to bottom, a fixture 51, a rotating device 52, and a lifting device 53 connected in sequence. The sensing mechanism 6 is used to detect whether the lead screw blank at the upper end of the fixture 51 is aligned. The rotating device 52 drives the fixture 51 to rotate. The upper end of the fixture 51 is provided with a first tooth 54 spaced apart. The lifting device 53 drives the first tooth 54 to reciprocate between the third station and the first station.

[0044] like Figures 3-4 As shown, the feeding mechanism 4 includes a loading box 41, a first moving device 42, and a carrier plate 43. The sensing mechanism 6 is disposed on the outer wall of the loading box 41. The loading box 41 has a discharge port at its lower end. The carrier plate 43 is slidably disposed below the discharge port. The second station, the carrier plate 43, and the first moving device 42 are arranged sequentially along the sliding direction of the carrier plate 43. The end of the carrier plate 43 near the second station is provided with a second tooth 44 at intervals. The first moving device 42 drives the second tooth 44 to move from below the discharge port to the second station. The first tooth 54 and the second tooth 44 are arranged alternately. The upper surfaces of the first tooth 54 and the second tooth 44 are provided with through grooves for accommodating the lead screw blank.

[0045] The feeding mechanism 4, the second pushing mechanism 8, the feeding device 9, and the first pushing mechanism 7 are arranged in sequence around the first workstation.

[0046] When the feeding mechanism 4 feeds material, the carrier plate 43 moves from the lower end of the loading box 41 to above the fixture 51. During this process, a lead screw blank will pass through the discharge port and fall into the through groove of the second tooth 44 at the end of the carrier plate 43. The second tooth 44 at the end of the carrier plate 43 will move above the first tooth 54 of the fixture 51, and the first tooth 54 and the second tooth 44 will intersect each other. When the fixture 51 rises, the first tooth 54 at the upper end of the fixture 51 will pass through the gap of the adjacent second tooth 44 and lift the lead screw blank on the second tooth 44. The lead screw blank is transferred from the carrier plate 43 to the upper end of the fixture 51. After the carrier plate 43 is reset, the fixture 51 can rotate.

[0047] The sensing mechanism 6 detects whether the lead screw blank is placed in reverse by sensing both ends of the lead screw. If the lead screw blank is placed in reverse, the rotating device 52 controls the fixture 51 to rotate 180° to rotate and straighten the lead screw blank so that the end of the lead screw blank to be threaded is aligned with the thread rolling machine 2. The lifting device 53 of the rotating mechanism 5 lifts the rotating device 52 and the fixture 51 to the first position, so that the lead screw blank and the feed port of the thread rolling machine 2 are at the same height.

[0048] After the lifting device 53 of the rotating mechanism 5 lifts the rotating device 52 and the fixture 51 to the first working position, the first pushing mechanism 7 pushes the lead screw blank at the upper end of the fixture 51 from the inside of the through groove of the first tooth 54 to the inside of the second pushing mechanism 8. During the process of moving the lead screw blank to the second pushing mechanism 8, the moving direction of the lead screw blank is parallel to the center line of the through groove.

[0049] After the lead screw blank enters the second pushing mechanism 8, the second pushing mechanism 8 moves the lead screw blank horizontally between the feeding device 9 and the inlet. During the movement, the direction of movement of the lead screw blank is perpendicular to the center line of the through groove, and the center line of the lead screw blank and the center line of the through groove remain parallel to each other. Finally, the feeding device 9 pushes the lead screw blank into the inlet of the thread rolling machine 2 for thread rolling.

[0050] like Figure 9 As shown, the feeding device 9 includes a first slide table 91, a feeding plate 92, a push rod 93, a first linear moving element 94, and a second linear moving element 95. The first slide table 91 is connected to the first linear moving element 94, and the push rod 93 is connected to the second linear moving element 95. The feeding plate 92 and the second linear moving element 95 are respectively disposed at both ends of the first slide table 91. A feeding groove is formed on the upper surface of the feeding plate 92, and the lower end of the push rod 93 is slidably disposed inside the feeding groove.

[0051] like Figure 8 As shown, the second pushing mechanism 8 includes a second moving device 81 and a second pushing block 82 connected to each other. A receiving groove 83 is formed on the surface of the second pushing block 82 near the first station. The center line of the receiving groove 83, the center line of the through groove, and the center line of the inlet are parallel to each other. The moving direction of the second pushing block 82 is perpendicular to the center line of the receiving groove 83.

[0052] like Figure 7 As shown, the first pushing mechanism 7 includes a third moving device 71 and a first pushing block 72 connected to each other. The first pushing block 72 has a protrusion that mates with the through groove at one end near the first station. The protrusion is positioned above the through groove. The protrusion is used to push the lead screw blank so that it slides along the through groove of the first tooth 54.

[0053] The loading box 41 includes a box body, a material channel 47, a bidirectional lead screw 45, and guide plates 46. The material channel 47 is inclinedly disposed inside the box body. The bidirectional lead screw 45 is rotatably disposed inside the material channel 47. The two guide plates 46 are symmetrically disposed and slidably disposed inside the material channel 47, and are threadedly connected to both ends of the bidirectional lead screw 45. When the bidirectional lead screw 45 rotates, the two guide plates 46 will move closer or further apart, changing the distance between the two guide plates 46 to accommodate lead screw blanks of various lengths. The width of the loading box 41 is adjustable to accommodate different types of lead screw blanks. During the material unloading process, there is no need to adjust the position of the lead screw, saving unloading time. The sensing mechanism 6 and the rotating mechanism 5 accurately identify the direction, avoiding problems such as defective products and module damage caused by incorrect placement of the lead screw blank.

[0054] like Figure 6 As shown, the sensing mechanism 6 includes a fourth moving device 61, a bracket 62, and a sensor 63. The sensor 63 is disposed at both ends of the bracket 62. The fourth moving device 61 and the bracket 62 are connected sequentially from top to bottom. The fourth moving device 61 drives the bracket 62 to move up and down. The fourth moving device 61 is used to drive the bracket 62 and the sensor 63 to move up and down. The fourth moving device 61 drives the bracket 62 and the sensor 63 to descend directly above the lead screw blank to facilitate the detection of the lead screw blank.

[0055] The first moving device 42, the second moving device 81, the third moving device 71, the fourth moving device 61, the first linear moving element 94, and the second linear moving element 95 are all any one of the following: cylinder, hydraulic cylinder, and linear module.

[0056] The first linear motion element 94 and the second linear motion element 95 can be dual-axis precision slide cylinders. A magnetic switch is provided on one side of the first linear motion element 94 and the second linear motion element 95 to limit their stroke. The first moving device 42, the second moving device 81, the third moving device 71, and the fourth moving device 61 are all cylinders.

[0057] The first moving device 42 may be a thin cylinder. A magnetic switch is provided on one side of the first moving device 42 to limit the stroke of the first moving device 42.

[0058] The second moving device 81 may be a dual-axis cylinder. A magnetic switch is provided on one side of the second moving device 81 to limit the stroke of the second moving device 81.

[0059] The third moving device 71 can be a pen-shaped cylinder to meet the large stroke requirements of the third moving device 71. A magnetic switch is provided on one side of the third moving device 71 to limit the stroke of the third moving device 71.

[0060] The fourth moving device 61 may be a dual-axis precision slide cylinder. A magnetic switch is provided on one side of the fourth moving device 61 to limit the stroke of the fourth moving device 61.

[0061] like Figure 1 As shown, the clockwise feeding device also includes a worktable 1 and a support frame 3. The thread rolling machine 2 is detachably mounted on the upper surface of the worktable 1, and the support frame 3 is detachably mounted on one end of the worktable 1. The feeding device 9, the second pushing mechanism 8, the first pushing mechanism 7, the rotating mechanism 5, and the feeding mechanism 4 are all mounted on the support frame 3. The second pushing block 82 of the second pushing mechanism 8 is slidably mounted on the upper surface of the support frame 3, and the receiving groove 83 is opened on the lower surface of the second pushing block 82. When the second pushing block 82 moves, the lead screw blank inside the receiving groove 83 will roll on the upper surface of the support frame 3.

[0062] One end of the support frame 3 is provided with an inverted L-shaped hanging plate, and one end of the worktable 1 is provided with a long groove. One end of the hanging plate is inserted into the long groove. The hanging plate and the long groove are detachably connected by a set screw, and the inner wall of the long groove is provided with a threaded hole that mates with the thread of the set screw.

[0063] The working process of this utility model is as follows:

[0064] First, the lead screw blanks to be rolled are neatly placed into the loading box 41 (the orientation does not need to be consistent). The lead screw blanks in the loading box 41 will fall into the through groove of the second tooth 44 at the end of the carrier plate 43. The first moving device 42 of the feeding mechanism 4 pushes the carrier plate 43 to move linearly, and the carrier plate 43 moves the lead screw blanks to the second station (located between the fixture 51 of the rotating mechanism 5 and the first station). The lifting device 53 of the rotating mechanism 5 lifts the fixture 51, so that the first tooth 54 at the upper end of the fixture 51 passes through the gap between two adjacent second teeth 44, and lifts the lead screw blanks on the carrier plate 43 through the first tooth 54. After the carrier plate 43 is reset, the lead screw blanks are transferred from the carrier plate 43 to the upper end of the fixture 51. At this time, the lead screw blanks follow the fixture 51 to rise to the first station. The fourth moving device 61 of the sensing mechanism 6 drives the bracket 62 to descend and sense whether the direction of the lead screw blanks is correct.

[0065] If the orientation is correct, the third moving device 71 of the first pushing mechanism 7 drives the first pusher block 72 to push the lead screw blank into the receiving groove 83 of the second pusher block 82. If the orientation is incorrect, the rotating device 52 of the rotating mechanism 5 rotates the fixture 51 and the lead screw blank 180° clockwise to adjust the orientation. Then, the third moving device 71 of the first pushing mechanism 7 drives the first pusher block 72 to push the lead screw blank into the receiving groove 83 of the second pusher block 82 of the second pushing mechanism 8. With the lead screw blank in the receiving groove 83 of the second pusher block 82 in the correct orientation, the second pushing mechanism 8 drives the second pusher block 82 and the lead screw blank to move through the second moving device 81. The lead screw blank will follow the movement of the second pusher block 82 and roll inside the receiving groove 83. The lead screw blank and the second pusher block 82 move onto the feeding plate 92 of the feeding device 9. The first linear moving element 94 of the feeding device 9 moves the lead screw blank and the feeding plate 92 together to the feed port of the thread rolling machine 2. Then, the second linear moving element 95 of the feeding device 9 pushes the push rod 93, and the lead screw blank is pushed into the thread rolling machine 2 for thread rolling.

[0066] In one embodiment, the lower end of the push rod 93 is provided with a vacuum suction hole, which is connected to a vacuum generator via a pipe. The support frame 3 has a stepped groove at one end near the feed inlet of the thread rolling machine 2, and a discharge device is provided inside the stepped groove. The discharge device is either a material channel 47 or a product receiving box. After the thread rolling of the lead screw blank is completed, the vacuum generator is activated. The vacuum generator sucks up the end of the lead screw blank away from the thread rolling machine 2 through the vacuum suction hole. Then, the feeding device 9 resets, pulling the lead screw blank out of the thread rolling machine 2. When the lead screw blank passes above the discharge device, the vacuum generator is turned off, and the push rod 93 pushes the lead screw blank, causing it to fall into the discharge device.

[0067] The technical features of the embodiments described above can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these should all be considered to be within the scope of this specification.
