An automatic screening and knocking device for bearing seat production

Abstract

This invention discloses an automatic screening and striking device for bearing housing production, comprising a first guide frame with a figure-eight shaped feeding section and a downwardly angled first guide section, a screening unit mounted on the first guide frame, and an automatic striking unit mounted on a second guide frame. The screening unit automatically intercepts bearing housings with punching waste and conveys them to the striking position on the second guide frame, while bearing housings without punching waste are directly handled. The automatic striking unit automatically strikes the opening at the upper end of the bearing housing that has moved to the striking position, causing the punching waste to detach from the bearing housing. This device automatically screens out bearing housings with punching waste through gravity, and then converts the gravitational potential energy of the bearing housing into kinetic energy through the inclined second guide section. This kinetic energy is then used as a power source to strike and remove the punching waste inside the bearing housing hole, eliminating the need for manual operation and effectively reducing production costs.

Description

Technical Field

[0001] This invention relates to the field of bearing housing manufacturing technology, and in particular to an automatic screening and tapping device for bearing housing production. Background Technology

[0002] The bearing housing for idler rollers is usually formed from metal discs through multiple stamping, stretching, shaping, punching, and trimming steps using a mold.

[0003] In the actual punching process of bearing housings, some punching waste often gets stuck in the holes and cannot be separated. After the edges are trimmed, the bearing housings are pushed onto the guide frame by a robot arm. The bearing housings move down the inclined surface of the guide frame and eventually enter the receiving box. It is necessary to hire additional personnel to screen out the bearing housings with punching waste stuck in the receiving box and use a hammering tool to knock the punching waste out of the holes, which increases labor costs. Therefore, this application provides an automatic screening and hammering device for bearing housing production to meet the needs. Summary of the Invention

[0004] The purpose of this application is to provide an automatic screening and tapping device for bearing housing production, which solves the problem of increased labor costs caused by the need to hire additional personnel to screen out bearing housings with punching waste and use a tapping tool to knock the punching waste out of the holes in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution: an automatic screening and tapping device for bearing housing production, comprising a first guide frame with a figure-eight shaped feeding section and a first guide section arranged obliquely downwards, and further comprising a screening unit installed on the first guide frame and an automatic tapping unit installed on a second guide frame, wherein the first guide frame is installed above the second guide frame, and the second guide section on the second guide frame is arranged obliquely downwards;

[0006] Screening unit: Automatically intercepts bearing seats with punching waste and conveys them to the tapping position on the second guide frame, while bearing seats without punching waste are directly connected;

[0007] The automatic striking unit automatically strikes the opening at the top of the bearing housing when it moves to the striking position, causing the punching waste to detach from the bearing housing.

[0008] In a preferred embodiment of this invention, the screening unit includes a rotating plate disposed within the opening of the first guide section. A rotating cylinder is fixed at the bottom of the rotating plate off-center. The inner cavity of the rotating cylinder is penetrated by a rotating shaft. Both ends of the rotating shaft are fixedly connected to the first guide frame. The rotating cylinder is rotatably connected to the rotating shaft through an internally disposed bearing. A weighting block is fixed at the bottom of the rotating plate near the rotating cylinder. An upper baffle and a lower baffle are disposed vertically at both ends of the rotating plate. The inner wall of the opening of the first guide section is provided with contact baffles that correspond to and are adapted to the upper baffle and the lower baffle.

[0009] In a preferred embodiment of this invention, a first stop is fixed on the inner wall of the rotating drum, and a second stop is fixed on the outer wall of the rotating shaft. The contact between the first stop and the second stop can prevent the right end of the rotating plate from continuing to rotate downward, so that the rotating plate eventually rotates to a suitable angle and guides the bearing seat sliding on it to the second guide frame.

[0010] In a preferred embodiment of this invention, the automatic striking unit includes two mounting plates mounted on the second guide frame and arranged opposite to each other. One of the mounting plates has a contact block with a direct triangular structure slidably disposed within its inner cavity. The inclined end of the contact block is located on the sliding path of the bearing seat. The contact block is connected to the inner wall of the mounting plate by a spring. A second rack is slidably disposed within the inner cavity of the mounting plate, and the second rack meshes with a first rack via a transmission gear. The first rack is fixed to the right-angled end face of the contact block. A movable rod is rotatably disposed on the second rack, and the upper end of the movable rod is rotatably connected to the upper end of a drive rod. The drive rod is rotatably connected to a support plate mounted on the mounting plate via a pin, the pin being positioned near the lower end of the drive rod. An arc-shaped toothed rod is fixed to the lower end of the drive rod, and the arc-shaped toothed rod meshes with an impact toothed column. The upper end of the impact toothed column slidably penetrates a limiting plate, which is mounted on the upper ends of the two mounting plates.

[0011] As a preferred embodiment of this invention, an assist unit is also included to help the bearing housing accelerate its downward movement.

[0012] In a preferred embodiment of this invention, the assist unit is configured as a magnet, and the magnet is disposed within a groove in the mounting plate.

[0013] In a preferred embodiment of this invention, the second guide section of the second guide frame is provided with a feeding opening.

[0014] In a preferred embodiment of this invention, the inclination of the second guide section of the second guide frame is greater than the inclination of the first guide section.

[0015] In summary, the technical effects and advantages of this invention are as follows:

[0016] The present invention has a reasonable structure. This device automatically filters out bearing seats with punching waste through gravity. Then, the gravitational potential energy of the bearing seat is converted into the kinetic energy of the bearing seat through the inclined second guide section. This kinetic energy is then used as a power source to knock away the punching waste in the hole of the bearing seat. No manual operation is required, which can effectively reduce production costs.

[0017] The invention also includes an assist unit for accelerating the downward movement of the bearing housing, so that it has enough kinetic energy to pass through the striking position, which is beneficial for the removal of stamping waste. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example: Reference Figure 1-2 An automatic screening and tapping device for bearing housing production is shown, including a first guide frame with a figure-eight shaped feeding section 1 and a first guide section 3 arranged at an angle downwards, and a screening unit 2 installed on the first guide frame and an automatic tapping unit 4 installed on a second guide frame 6. The first guide frame is installed above the second guide frame 6, and the second guide section on the second guide frame 6 is arranged at an angle downwards.

[0029] Screening unit 2: Automatically intercepts bearing seats 5 with punching waste and conveys them to the striking position on the second guide frame 6, while bearing seats 5 without punching waste are directly connected;

[0030] The automatic striking unit 4 automatically strikes the opening at the upper end of the bearing seat 5 when it moves to the striking position, causing the punching waste to be removed from the bearing seat 5.

[0031] As a preferred embodiment of this example, Figure 2-4As shown, the screening unit 2 includes a rotating plate 21 disposed inside the opening of the first guide section 3. A rotating cylinder 25 is fixed at the bottom of the rotating plate 21 off-center. The inner cavity of the rotating cylinder 25 is penetrated by a rotating shaft 26. The two ends of the rotating shaft 26 are fixedly connected to the first guide frame. The rotating cylinder 25 is rotatably connected to the rotating shaft 26 through an internally disposed bearing. A weighting block 22 is fixed at the bottom of the rotating plate 21 near the rotating cylinder 25. An upper baffle 23 and a lower baffle 24 are disposed vertically at both ends of the rotating plate 21. The inner wall of the opening of the first guide section 3 is provided with contact baffles 29 that correspond to and are adapted to the upper baffle 23 and the lower baffle 24.

[0032] When the bearing seat 5 is pushed onto the first guide section 3, it will move downwards along the inclined plane. When it moves onto the rotating plate 21, if there is punching waste stuck in the hole of the bearing seat 5, its own weight is relatively heavy. When it moves to the right side of the rotating drum 25, the rotating plate 21 will rotate, and the right end of the rotating plate 21 will rotate downwards, eventually guiding the bearing seat 5 to the second guide section of the second guide frame 6, and then accelerating downwards along the inclined plane of the second guide section. When the bearing seat 5 moves to the second guide section... When the material rack 6 is in place, its rotating plate 21 rotates in the opposite direction and returns to its original position under the gravity of the weight block 22. At this time, the lower end of the upper baffle 23 and the upper end of the lower baffle 24 respectively abut against the corresponding contact baffle 29. The inclination of the rotating plate 21 is consistent with the first guide section 3. If there is no punching waste stuck in the hole of this bearing seat 5, its own weight is relatively light, the rotating plate 21 does not rotate, and its bearing seat 5 will move directly along the first guide section to the receiving box. The screening unit 2 can automatically screen according to gravity.

[0033] It should be noted that when the metal disc is stamped into the bearing seat 5, lubricating oil is sprayed on the metal disc. After stamping, the bearing seat 5 will still have residual lubricating oil, which can reduce the friction between the bearing seat 5 and the first guide frame and the second guide frame 6, and facilitate the rapid sliding of the bearing seat 5.

[0034] As a preferred embodiment of this example, Figure 4 As shown, a first stop 27 is fixed on the inner wall of the rotating drum 25, and a second stop 28 is fixed on the outer wall of the rotating shaft 26. The contact between the first stop 27 and the second stop 28 can prevent the right end of the rotating plate 21 from continuing to rotate downward, so that the rotating plate 21 eventually rotates to a suitable angle and guides the bearing seat 5 sliding on it to the second guide frame 6.

[0035] The first stop 27 and the second stop 28 are set to prevent the rotating plate 21 from rotating excessively, which would increase the interval time for it to return to its original position. The increased interval time would reduce the screening efficiency of the bearing seat 5, making it unable to keep up with the stamping speed of the bearing seat 5, resulting in material accumulation. According to the positional coordination of the first stop 27 and the second stop 28, the rotating plate 21 can be rotated at a certain angle to guide the bearing seat 5 to the second guide frame and allow the bearing seat 5 to continue sliding on the second guide section, while minimizing the interval time for the rotating plate 21 to return to its original position.

[0036] As a preferred embodiment of this example, Figure 5 and Figure 6 As shown, the automatic tapping unit 4 includes two mounting plates 41 mounted on the second guide frame 6 and arranged opposite each other. A contact block 42 with a direct triangular structure is slidably disposed within the inner cavity of one of the mounting plates 41. The inclined end of the contact block 42 is located on the sliding path of the bearing seat 5. The contact block 42 is connected to the inner wall of the mounting plate 41 by a spring 46. A second rack 44 is slidably disposed within the inner cavity of the mounting plate 41, and the second rack 44 meshes with a first rack 43 via a transmission gear 45. The first rack 43 is fixed at the right angle of the contact block 42. On the end face, a movable rod 47 is rotatably mounted on the second rack 44, and the upper end of the movable rod 47 is rotatably connected to the upper end of the drive rod 48. The drive rod 48 is rotatably connected to the support plate 49 mounted on the mounting plate 41 via a pin 410. The pin 410 is located near the lower end of the drive rod 48. An arc-shaped toothed rod 412 is fixed to the lower end of the drive rod 48, and the arc-shaped toothed rod 412 meshes with the impact toothed rod 413. The upper end of the impact toothed rod 413 slides through the limiting plate 411, and the limiting plate 411 is mounted on the upper ends of the two mounting plates 41.

[0037] Because the second guide section is inclined, the speed of the bearing seat 5 sliding on it will increase under the action of gravity. The rapidly moving bearing seat 5 will be squeezed out of the contact block 42 and press against it, causing the contact block 42 to move towards the inner cavity of the mounting plate 21. In conjunction with the first rack 43, which meshes with the second rack 44 through the transmission gear 45, the lower end of the movable rod 47 can move closer to the bearing seat 5. The movable rod 47 drives the drive rod 48 to rotate downward around the pin 410. The arc-shaped toothed rod 412 drives the impact toothed column 413 to impact the bearing. The stamping waste in the hole of bearing seat 5 is knocked off. After that, the moving bearing seat 5 separates from the contact block 42. Through the elastic force of spring 46, the impact tooth 413 returns to its original position, and the bearing seat 5 continues to slide with its remaining kinetic energy and eventually enters the receiving box (its stamping waste is also carried to the receiving box by the bearing seat). This automatic knocking unit converts the gravitational potential energy of bearing seat 5 into the kinetic energy of bearing seat 5 through the inclined second guide section, and then uses this part of the kinetic energy as a power source to knock away the stamping waste in the hole of bearing seat 5.

[0038] It should be noted that the pin 410 is positioned close to the lower end of the drive rod 48, so that the drive rod 48, the movable rod 47, and the impact tooth 413 form a force-saving lever. By applying a small upward force to the long force-cutting end of the drive rod 48, a large force will be applied to the lower end of the drive rod 48 to drive the impact tooth 413 to move downward, which is beneficial to knocking off the stubborn punching waste in the bearing seat.

[0039] As a preferred embodiment of this example, Figure 6 As shown, it also includes an assist unit for accelerating the downward movement of the bearing housing 5.

[0040] As a preferred embodiment of this example, Figure 6 As shown, the assist unit is configured as a magnet 7, and the magnet 7 is disposed in the groove of the mounting plate 41.

[0041] The magnetic force of the magnet 7 can generate an attractive force on the bearing seat 5, which can accelerate the sliding bearing seat 5 so that it has enough kinetic energy to pass through the striking position and finally enter the receiving trough.

[0042] It should be noted that: First, there is no second guide section at the corresponding position of the magnet 7. That is, when the second guide end is between the positions of the magnet 7 and the position of the magnet 7, the bearing seat 5 is in a suspended state and the magnet 7 cannot hold the bearing seat 5, so the bearing seat 5 moves into the receiving box. By not setting a second guide section at the corresponding position of the magnet 7, the magnetism of the magnet 7 can be increased accordingly, which can further accelerate the bearing seat 5 so that it has enough kinetic energy to pass through the striking position. Second, in order to avoid the magnetic force generated by the magnet 7 from affecting other components, a magnetic shielding coating can be set on the outer surface of the affected components.

[0043] As a preferred embodiment of this example, Figure 1 As shown, the second guide section of the second guide frame 6 is provided with a discharge opening 8, which can be placed at the striking position to receive the falling stamping waste. The discharge opening 8 can reduce the contact area with the bottom of the bearing seat 5, thereby reducing friction and increasing the sliding speed of the bearing seat 5.

[0044] It is important to note that the material discharge opening 8 should be set as large as possible to minimize the contact area with the bearing housing 5.

[0045] As a preferred embodiment of this example, Figure 7 As shown, the inclination of the second guide section of the second guide frame 6 is greater than the inclination of the first guide section 3.

[0046] The inclination of the second guide section is greater than that of the first guide section 3, which helps to accelerate the sliding of the bearing 5 on the second guide section. The inclination of the first guide section 3 is small, and there is no speed requirement for the bearing seat 5 sliding on it. However, in order to ensure that the bearing seat 5 on the first guide section 3 does not deviate from the receiving box due to excessive speed when discharging material, the inclination of the first guide section 3 is set as small as possible.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
