An arrangement mechanism and a heat treatment production line

Abstract

The present invention discloses a placement mechanism and a heat treatment production line, including a mounting frame, on which a leveling structure for evenly distributing constant velocity joints is installed. It further includes: a support frame, on which a second motor is fixedly installed. A aligning structure for conveying constant velocity joints is jointly installed between the driving end of the second motor and the support frame. Rotating frames are fixedly installed on both sides of the support frame. By analyzing the shape of the constant velocity joint and using the gravity effect to convey it orderly and arrange it neatly, the spacing of the constant velocity joints before placement is made consistent. Then, the gravity of itself is used to uniformly clamp the aligned constant velocity joints, and its rotational force is used as the driving force for the release of the constant velocity joint, so that the constant velocity joint tilts and is given a certain acceleration to be placed on the conveyor belt. Through the support of the initial momentum and static friction, the constant velocity joint can be effectively prevented from tipping over, and at the same time, the placement effect and efficiency of the constant velocity joint are improved.

Description

Technical Field

[0001] The present invention relates to the technical field of production of constant velocity joints, and particularly relates to an arrangement mechanism and a heat treatment production line. Background Art

[0002] Constant velocity joints are important components in a car's transmission system. During the production process of constant velocity joints, normalizing treatment is a key step to ensure good performance and long-term durability during use. The correct arrangement of constant velocity joints not only ensures the effect and quality of the heat treatment process but also improves the operating efficiency of the production line. In the existing heat treatment steps of constant velocity joints, manual arrangement of constant velocity joints is required before normalizing.

[0003] When manually arranging constant velocity joints, due to limited operating space or improper arrangement, the utilization of the furnace space may be insufficient, affecting the efficiency and production capacity of the heat treatment equipment. Moreover, the arrangement position or method of constant velocity joints may vary due to human factors, thus affecting the heat treatment results of the parts and the quality of the final product. At the same time, operators need to take special protective measures in a high-temperature environment to avoid heat injuries or other accidents.

[0038] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure

[0039] Please refer to Figures 1 - 4, a placement mechanism and a heat treatment production line provided by an embodiment of the present invention include a mounting frame 4. A feeding hopper 2 for uniformly placing ball cage parts is fixedly installed on the mounting frame 4. The ball cage parts before normalizing are uniformly placed in the feeding hopper 2 and wait to be conveyed for subsequent normalizing. A guide plate 12 is fixedly installed at the lower port of the feeding hopper 2. The guide plate 12 is in an inclined state, which can prevent the ball cage parts falling from the feeding hopper 2 from falling on the ground. A first motor 6 is fixedly installed on one side of the mounting frame 4. The driving end of the first motor 6 penetrates through the mounting frame 4 and is installed with a concave conveyor belt 9 through a belt transmission assembly. The belt transmission assembly includes two transmission rods rotatably installed on the mounting frame 4. One of the transmission rods penetrates through the mounting frame 4 and is fixedly connected to the driving end of the first motor 6. Pulley two is fixedly installed on both transmission rods. The concave conveyor belt 9 is rotatably sleeved between the two pulley twos, and the upper surface of the concave conveyor belt 9 is provided with arc-shaped grooves at equal intervals.

[0040] A partition plate 11 for initially distributing the ball cage parts falling from the feeding hopper 2 is fixedly installed on the mounting frame 4. The height of the partition plate 11 is less than the vertical height of the ball cage parts, which can ensure that the ball cage parts are in an inclined or lying state when falling, prevent the ball cage parts from piling up, and can improve their alignment speed. A separation plate 10 is fixedly installed on the mounting frame 4. The separation plate 10 and the side shape of the concave conveyor belt 9 form a plurality of circular holes (refer to Figure 3 ), and the diameter of the circular hole is slightly larger than the maximum diameter of the end face of the ball cage part, which can enable the ball cage part to lie vertically flat in the arc-shaped groove of the concave conveyor belt 9. And under the shape setting of the separation plate 10, it is ensured that the ball cage parts can be conveyed sequentially along the arc-shaped grooves on the concave conveyor belt 9.

[0041] It further includes: a support frame 8. A second motor 7 is fixedly installed on the support frame 8. Two rotating shafts 15 are rotatably installed on the support frame 8. A second motor 7 is fixedly installed on the support frame 8. One of the rotating shafts 15 penetrates through the support frame 8 and is fixedly connected to the driving end of the second motor 7. A plurality of pulley ones 14 are fixedly installed on both rotating shafts 15. The plurality of pulley ones 14 are evenly distributed. A conveyor strip 16 is jointly rotatably sleeved between the corresponding two pulley ones 14. And the horizontal distance between two adjacent conveyor strips 16 is less than the maximum diameter of the end face of the ball cage part and greater than the minimum diameter of the end face of the ball cage part, which can enable the ball cage part to be in a suspended state between the two conveyor strips 16, with its larger-diameter end located above the conveyor strip 16 and its smaller-diameter end located below the conveyor strip 16.

[0042] A retaining plate 17 is fixedly installed on the support frame 8, and each conveyor strip 16 penetrates through the retaining plate 17. A plurality of through holes are formed in the retaining plate 17, and each through hole is respectively located between two adjacent conveyor strips 16. The retaining plate 17 can block the advancement of the ball cage parts, so that the ball cage parts conveyed by the conveyor strips 16 are orderly gathered on one side of the retaining plate 17 and wait for subsequent clamping.

[0043] Please refer to Figures 4 - 6 , rotating frames are fixedly installed on both sides of the support frame 8. A third motor 13 is fixedly installed on the support frame 8. The driving end of the third motor 13 is fixedly installed with a rotating rod 19, and the end of the rotating rod 19 away from the third motor 13 rotates on the support frame 8. A one-way bearing 22 is rotatably sleeved on the outer side of the rotating rod 19. Multiple spring rods 21 are fixedly installed on the one-way bearing 22. Multiple sliders 23 are fixedly installed on the multiple spring rods 21. An eccentric shaft 3 is rotatably sleeved on the outer side of the one-way bearing 22. The axis of the eccentric shaft 3 and the axis of the rotating rod 19 are at two shaft points. And the diameter of the eccentric shaft 3 on the side away from the mounting frame 4 on the rotating rod 19 is larger. Multiple annular convex grooves 18 are formed on the eccentric shaft 3, and the end face shape of the annular convex grooves 18 is circular, and its center is at the same point as the axis of the eccentric shaft 3. Multiple sliders 23 slide in the corresponding annular convex grooves 18 respectively. The eccentric shaft 3 is separated under the arrangement of the multiple annular convex grooves 18 (refer to Figure 5 ). After separation, the eccentric shaft 3 is fixedly connected with the abutting plate 17 (not shown in the figure). Both ends of the eccentric shaft 3 are fixedly connected to the support frame 8.

[0044] When the third motor 13 is turned on, it can drive the rotating rod 19 to rotate. The rotation of the rotating rod 19 can drive multiple spring rods 21 to rotate through the one-way bearing 22. The rotation of the multiple spring rods 21 can cause elastic expansion and contraction under the action of the sliders 23 and the annular convex grooves 18. When the spring rod 21 reaches the position on the side away from the feeding hopper 2 and parallel to the ground, at this time, the spring rod 21 reaches the longest length under the cooperation of the annular convex groove 18 and the slider 23.

[0045] Please refer to Figures 6 - 11, further comprising a plurality of clamping structures, the plurality of clamping structures are respectively installed on corresponding spring rods 21, the clamping structures clamp the ball cage parts aligned on the conveying strip 16. The clamping structure includes a spring shaft 24 fixedly installed at the lower end of the spring rod 21. Half-ring clamps 20 are rotatably installed on both sides of the spring shaft 24. The two half-ring clamps 20 can rotate on the spring shaft 24. A plurality of bent pipes 25 are fixedly communicated with both of the two half-ring clamps 20. Two ports of the plurality of bent pipes 25 are respectively located on the side where the two half-ring clamps 20 are close to each other. Spring three 37 is fixedly installed in the upper port of each of the plurality of bent pipes 25, and spring two 36 is fixedly installed in the lower port of each of the plurality of bent pipes 25. One end of each of the plurality of spring three 37 is fixedly installed with a piston plate two 38, and one end of each of the plurality of spring two 36 is fixedly installed with a piston plate one 35. The piston plate one 35 and the piston plate two 38 are both sealed and slid in the corresponding bent pipe 25. One side of each of the plurality of piston plates one 35 is fixedly installed with a connecting rod one 34, and one end of each of the plurality of connecting rod one 34 is fixedly installed with a cushion block one 33. One side of each of the plurality of piston plates two 38 is fixedly installed with a connecting rod two 40, and one end of each of the plurality of connecting rod two 40 is fixedly installed with a cushion block two 39; in the initial state (when the ball cage part is not clamped), at this time, the distance between the plurality of cushion blocks one 33 is relatively close and located outside the bent pipe 25 (the distance between the plurality of cushion blocks one 33 is less than the maximum diameter of the end face of the ball cage part), the distance between the plurality of cushion blocks two 39 is relatively farther than the distance between the cushion blocks one 33 and located inside the bent pipe 25 (the distance between the plurality of cushion blocks two 39 is greater than the maximum diameter of the end face of the ball cage part). The cushion block one 33 and the cushion block two 39 are both provided with inclined surfaces. The inclined surface shape can enable the ball cage part to enter well between the cushion block one 33 and the cushion block two 39 for relative locking. The inclined surface-shaped cushion block one 33 and cushion block two 39 can also be provided in a spherical shape, which can reduce the probability of jamming when the ball cage part enters between the plurality of cushion blocks one 33 and the plurality of cushion blocks two 39.

[0046] Push rods 28 are respectively fixedly installed on the two half-ring clamps 20. An installation shell 27 is jointly installed between the two push rods 28. A fixed plate 30 is fixedly installed in the installation shell 27. A liquid inlet hole is opened on the fixed plate 30. An extrusion plate 29 is sealed and slid in the installation shell 27. Liquid (such as hydraulic oil) is filled between the extrusion plate 29 and the fixed plate 30, which can improve the effect when the extrusion plate 29 extrudes downward ( Figure 9 in the direction shown); a spherical rod 26 is fixedly installed on the extrusion plate 29. The two push rods 28 are both slid on the installation shell 27. Sealing plates 32 are fixedly installed at the ends of the two push rods 28 close to each other. The two sealing plates 32 are both sealed and slid between the lower surface of the fixed plate 30 and the installation shell 27. A spring one 31 is jointly fixedly installed between the two sealing plates 32. When the extrusion plate 29 extrudes downward, the liquid will enter between the two sealing plates 32 through the liquid inlet hole. At this time, the two sealing plates 32 move away from each other, and the angle between the two half-ring clamps 20 is increased through the two push rods 28.

[0047] Please refer to Figure 1 and Figure 12 , and further includes a heating furnace 1. Inside the heating furnace 1, there is a conveyor belt for normalizing the transmission ball cage parts. Two support rods 41 are fixedly installed on the heating furnace 1. Between the heating furnace 1 and the two support rods 41, a trigger structure for cooperating with the clamping structure is installed. The trigger structure uses rotational force to unload the clamped ball cage parts, then drives the ball cage parts to tilt to lower their center of gravity and gives an acceleration to make them neatly arranged on the conveyor belt inside the heating furnace 1 for subsequent normalizing.

[0048] The trigger structure includes pressing plates 43 respectively fixedly installed on the two support rods 41. A connecting plate is fixedly installed between the two pressing plates 43. Multiple pressing plates 43 are also fixedly installed on the connecting plate. And spherical grooves are provided on the multiple pressing plates 43 for cooperating with the spherical rods 26.

[0049] A cross bar is fixedly installed between the two support rods 41. An inclined plate 5 is rotatably installed on the cross bar. Multiple guiding grooves for cooperating with the ball cage parts can be provided on the inclined plate 5. And the multiple guiding grooves are arranged parallel to the length direction of the conveyor belt on the heating furnace 1, which can drive the ball cage parts to be in an equidistant state on the inclined plate 5, ensuring that the ball cage parts fall on the conveyor belt with equal spacing. Two racks 45 are fixedly installed on the lower surface of the inclined plate 5. Two folding plates 42 are fixedly installed on the outside of the heating furnace 1. Sliding grooves are opened on the two folding plates 42. Spring four 48 is fixedly installed in each of the two sliding grooves. The upper ends of the two spring four 48 are fixedly installed with a toothed rod 46 sliding in the sliding groove. Protrusions are provided on both sides of the toothed rod 46, which can drive the toothed rod 46 to slide in the sliding groove but will not separate from the folding plate 42. And in the initial state, the inclined plate 5 is in a horizontal state and the spring four 48 is in a normal state (no stretching or compression). Two knocking plates 47 are fixedly installed on the two toothed rods 46. Spherical grooves are also provided on the knocking plates 47 for cooperating with the spherical rods 26. Two connecting frames are fixedly installed on the heating furnace 1. Gears 44 are rotatably installed on the two connecting frames. And the gears 44 are respectively meshed with the corresponding racks 45 and toothed rods 46.

[0050] The working principle of the present invention is as follows:

[0051] The ball cage parts to be normalized are placed in the discharge hopper 2. Under the action of gravity, the ball cage parts fall onto the concave conveyor belt 9 through the guide plate 12. The motor 1 6 is turned on to drive the ball cage parts on the concave conveyor belt 9 to be conveyed. The ball cage parts pass through the partition plate 11 and the separation plate 10 successively, so that the ball cage parts are in a vertically lying state in the arc-shaped groove. However, the positive and negative order of the ball cage parts lying flat is different at this time. At the same time, the motor 2 7 is turned on to drive multiple conveying bars 16 to rotate through the rotating shaft 15. The conveying bars 16 rotate to receive the ball cage parts lying flat on the concave conveyor belt 9. At the same time, under the action of the distance between the conveying bars 16, the ball cage parts are in an upside-down state on the conveying bars 16 as a whole, and are neatly arranged on one side of the abutment plate 17 under the obstruction of the abutment plate 17 to wait for subsequent clamping.

[0052] When it is necessary to clamp the ball cage parts hanging upside down on the conveying bar 16, the rotation of the multiple spring rods 21 will drive each half-ring clamp 20 to rotate around the axis of the rotating rod 19, and clamp the row of ball cage parts closest to the abutment plate 17 through the perforations on the abutment plate 17, so that the ball cage parts enter between the two half-ring clamps 20 (in Figure 1 The plurality of pads 1 33 are squeezed under the gravity of the ball cage, and the plurality of pads 1 33 move away from each other, and the plurality of piston plates 1 35 are driven by the plurality of connecting rods 1 34 to squeeze the corresponding springs 2 36. At this time, the closed space in the elbow 25 becomes smaller, and the upper piston plate 2 38 is squeezed toward the direction close to the upper end of the elbow 25, so that the plurality of pads 2 39 are close to each other, so that the plurality of pads 2 39 clamp the ball cage, and at the same time, the elastic clamping of the two half-ring clamps 20 and the spring shaft 24 ensures that the ball cage will not be separated during the rotation of the spring rod 21.

[0053] When the spring rod 21 rotates to be parallel to the ground (close to the side of the heating furnace 1), the multiple spherical rods 26 just abut against the spherical grooves on the multiple pressing plates 43. Under the action of the rotational force, the spherical rod 26 squeezes the squeezing plate 29, so that the liquid in the mounting shell 27 enters between the two sealing plates 32 through the fixing plate 30, so that the two sealing plates 32 move away from each other. The two sealing plates 32 move through the corresponding push rods 28 to drive the two half-ring clamps 20 away from each other (the diameter between the two half-ring clamps 20 is greater than the maximum diameter of the end face of the ball cage member). At this time, the ball cage member is disengaged from the clamping and falls onto the inclined plate 5. At this time, with the driving force of the motor three 13, the spherical rod 26 is driven to continue to rotate. When the spherical rod 26 is separated from the multiple pressing plates 43, the squeezing plate 29, the two sealing plates 32, the piston plate one 35 and the piston plate two 38 are driven to return to the initial state under the elastic force of the spring one 31, the spring two 36 and the spring three 37.

[0054] Subsequently, the two outermost spherical rods 26 will abut against the two percussion plates 47, causing them to slide downward in the sliding grooves on the folding plate 42. The downward sliding of the rack bar 46 will drive the rack 45 to move upward through the gear 44, thereby causing the inclined plate 5 to be in an inclined state, driving the constant velocity joint parts falling on the inclined plate 5 to slide downward onto the conveyor belt of the heating furnace 1, giving the constant velocity joint parts a certain initial acceleration, and at the same time making them in an inclined state, so that the constant velocity joint parts have a certain momentum when starting to move on the conveyor belt. This helps to avoid the situation where the constant velocity joint parts slide or topple due to insufficient static friction on the conveyor belt. When the spherical rod 26 separates from the percussion plate 47, at this time, under the elastic force of the fourth spring 48, the inclined plate 5 is driven to return to the horizontal state again.

[0055] Only certain exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
