Description

[0001] The utility model relates to the technical field of toy wheel assembly, in particular to a remote control car tire assembly device based on secondary wheel hub press-fitting. Background Art

[0002] In the current toy wheel hub assembly process, a key problem often faced is that the bearing rod and the roller are easily separated from the press-fitting chamber during the press-fitting process, which not only seriously affects the assembly efficiency, but also may cause component damage and increase production costs.

[0003] Specifically, traditional assembly equipment often lacks a sophisticated control system and a stable press-fitting mechanism, which makes it easy for bearing rods and rollers to shift or pop out of the press-fitting chamber when under pressure during the press-fitting process. This not only interrupts the assembly process, but also requires manual intervention by staff to readjust the position and press-fit again, greatly reducing production efficiency. In addition, existing assembly equipment is often designed to be convenient for secondary press-fitting of bearing rods and rollers. In actual operation, if the first press-fitting fails to achieve the desired effect, staff often need to spend a lot of time and energy to disassemble and reassemble, which not only increases the difficulty of operation, but may also cause components to be damaged due to frequent disassembly and assembly.

[0029] The workpiece is divided into a bearing rod 11 and a roller 12. The disc feeder 3 has a pair, one of which is used to vibrate and convey the bearing rod 11, and the other disc feeder 3 is used to vibrate and convey the roller 12. The first press mechanism 4 is used to feed the roller 12. The second press mechanism 5 is used to convey the bearing rod 11, and the drive unit 6 is used to dock and press the roller 12 and the bearing rod 11 in the first press mechanism 4 and the second press mechanism 5, respectively. The press fitting of the bearing rod 11 and the roller 12 is realized, and the bearing rod 11 and the roller 12 are both made of plastic and have plasticity. By starting the disc feeder 3, the bearing rod 11 and the roller 12 are driven to fall into the first press mechanism 4 and the second press mechanism 5, respectively. The roller 12 that falls into the first press mechanism 4 can be moved by the drive unit 6, and then the drive unit 6 pushes the bearing rod 11 in the second press mechanism 5 to move until the roller 12 is inserted into the bearing rod 11. The assembly of the bearing rod 11 and the roller 12 is completed, and the press-fitting and docking of the bearing rod 11 and the roller 12 is realized, which prevents the bearing rod 11 from being separated from the outer side of the roller 12 after the press-fitting, and speeds up the production efficiency of the product.

[0030] See also Figure 3 and Figure 4As shown, the first pressing mechanism 4 includes a first feed box 41, a first material placement block 42 and a material conveying pipeline 43; the first feed box 41 is arranged on the frame 2, and the first feed box 41 is used to receive the material on the disc feeder 3; the first material placement block 42 is arranged in the first feed box 41; the material conveying pipeline 43 has a plurality of and is respectively arranged on the first feed box 41 and the disc feeder 3; the first material placement block 42 is provided with a plurality of first discharge troughs 44 arranged at equal distances.

[0031] The roller 12 falls into the first feed box 41 through the disc unloader 3 and the feed pipe 43, and then falls into the first discharge trough 44 opened on the first loading block 42. At this time, the roller 12 is perpendicular to the first discharge trough 44. The size of the first discharge trough 44 is larger than the outer diameter of the roller 12, so that the roller 12 falls into the first discharge trough 44 in a vertical state when passing through the feed pipe 43.

[0032] See also Figure 6 and Figure 7 As shown, a plurality of equally spaced first pouring grooves 45 are provided on the first material placement block 42 . The first pouring grooves 45 are close to one side of the first material discharge groove 44 . The first pouring grooves 45 are provided in a vertical direction relative to the first material discharge groove 44 .

[0033] The depth of the first pouring groove 45 is equal to the diameter of the roller 12, and the diameter of the first pouring groove 45 is equal to the diameter of the roller 12. The first pouring groove 45 is used to limit the roller 12 to be able to stably adhere to the outer wall of the first pouring groove 45 and tilt, to prevent the roller 12 from tipping over in the first discharge groove 44 and the first pouring groove 45, causing the position of the roller 12 to change.

[0034] See also Figure 5 and Figure 6 As shown, the second pressing mechanism 5 includes a second feed box 51; the second feed box 51 is arranged on the frame 2 and close to one side of the first feed box 41; a second material loading trough 52 is provided on the second feed box 51; a plurality of second discharge troughs 53 close to one side of the second material loading trough 52 are provided on the second feed box 51; and a second pouring trough 54 arranged in a vertical direction relative to the second discharge trough 53 is provided on the second feed box 51.

[0035] The disc unloader 3 conveys the bearing rod 11 to the second feed box 51 through the conveying pipe, and then drops it into the second discharge trough 53 opened on the second material trough 52. The second discharge trough 53 matches the outer diameter of the bearing rod 11, so that the bearing rod 11 can smoothly pass through the conveying pipe 43 and fall into the second discharge trough 53, and after falling, it is located in the second discharge trough 53 and the second dumping trough 54 in a vertical state.

[0036] See also Figure 6 and Figure 7As shown, the driving unit 6 includes a mounting frame 61, a telescopic cylinder 62, a push rod 63 and a pushing block 64; the mounting frame 61 has a pair and is respectively arranged on the first feed box 41 and the second feed box 51; the telescopic cylinder 62 has a pair and is respectively installed on the mounting frame 61; the push rod 63 is slidably arranged at the output end of the telescopic cylinder 62; the pushing block 64 is slidably arranged on the frame 2 and is connected to the push rod 63.

[0037] When the bearing rod 11 and the roller 12 located in the first discharge groove 44 and the second discharge groove 53 are press-fitted and docked, the telescopic cylinder 62 arranged on the first feed box 41 is first started. When the telescopic cylinder 62 is started, the push rod 63 is driven to move. When the push rod 63 moves, it can drive the push block 64 to move synchronously.

[0038] See also Figure 6-Figure 8 As shown, the driving unit 6 also includes an abutment block 66 and a first contact block 67; two symmetrically arranged ejection grooves 65 are opened on the second feed box 51, and the ejection grooves 65 are clearance-matched with the pushing block 64; the abutment block 66 has a pair and is respectively arranged on the pushing block 64, and the abutment blocks 66 are respectively located in the first discharge groove 44 and the second discharge groove 53 and slide; the first contact block 67 has a pair and is respectively arranged on the pushing block 64, and the first contact block 67 is located in the ejection groove 65 and slides.

[0039] The first contact block 67 located in the first feed box 41 and in contact with the roller 12 is provided with a through hole for the bearing rod 11 to pass through, so that the bearing rod 11 and the roller 12 can be stably docked for the second press-fitting. When the push block 64 moves, it can drive the first contact block 67 and the abutment block 66 fixedly connected thereto to contact the roller 12 located in the first discharge groove 44 and the first dumping groove 45. After the contact, the abutment block 66 can first contact the roller 12, and can push the roller 12 along the first dumping groove 45 until the roller 12 dumps in the first dumping groove 45. After dumping, the first contact block 67 can push the dumped roller 12 along the first discharge groove 44 and the ejection groove 65 until the roller 12 is pushed out of the first feed box 41. In this state, half of the roller 12 is located in the first feed box 41, and the other half is located outside the first feed box 41. At this time, the first press-fitting push of the roller 12 is completed.

[0040] See also Figure 1-Figure 8 As shown, the driving unit 6 also includes a fixed limiting block 68, a press-fitting chamber 69 and a collection box 691; the fixed limiting block 68 is arranged on the second feed box 51 and close to one side of the ejection groove 65; the press-fitting chamber 69 is arranged on the frame 2 and is located between the first feed box 41 and the second feed box 51; the collection box 691 is arranged on the base 1 and is located below the press-fitting chamber 69.

[0041] A positioning groove for the roller 12 to pass through is provided on the press-fitting chamber 69, and the size of the positioning groove matches the size of the roller 12. An avoidance groove for the bearing rod 11 to pass through is provided on the fixed limiting block 68. When half of the roller 12 is located outside the first feed box 41, the telescopic cylinder 62 provided on the second feed box 51 is started, and then the push block 64 is started to move, at which time the first contact block 67 located in the second material loading trough 52 can be driven to move synchronously, and the bearing rod 11 located in the second discharge trough 53 and the second dumping trough 54 can be dumped away from the second discharge trough 53 until the bearing rod 11 moves out of the second feed box 51. Then, the bearing rod 11 can pass through the fixed limiting block 68 through the avoidance groove and continue to move until the bearing rod 11 is located in the press-fitting chamber. The roller 12 passes through the chamber 69 to complete the secondary press-fitting. After the press-fitting is completed, the bearing rod 11 can prop up the roller 12 to increase the diameter of the roller 12. The telescopic cylinder 62 arranged on the first feed box 41 is started to drive the roller 12 and the bearing rod 11 after press-fitting to move in the press-fitting chamber 69. When moving, due to the larger size of the roller 12 after press-fitting, the assembled roller 12 is restricted by the abutment groove and disengaged from the first contact block 67. After disengagement, it can fall into the collection box 691 arranged on the frame 2, thereby realizing the automatic withdrawal and collection of the bearing rod 11 and roller 12 after press-fitting.

[0042] Working principle: By starting the disc feeder 3, the bearing rod 11 and the roller 12 are respectively sent to the first press-fitting mechanism 4 and the second press-fitting mechanism 5. The roller 12 falls into the first feed box 41 through the feed pipe 43, and then falls into the first discharge trough 44 of the first material storage block 42, maintaining a vertical state. The size of the first discharge trough 44 is larger than the outer diameter of the roller 12 to ensure that the roller 12 falls in stably. The first dumping trough 45 is the same length as the center line of the roller 12 and has the same outer diameter to ensure that the roller 12 is stably fitted and tilted to avoid position changes. The bearing rod 11 enters the second feed box 51 through the conveying pipe and falls into the second discharge trough 53 of the second material storage trough 52. The second discharge trough 53 matches the outer diameter of the bearing rod 11, so that it is stably placed vertically. When performing press-fit docking, first start the telescopic cylinder 62 on the first feed box 41 to drive the push rod 63 to drive the push block 64 to move. The abutment block 66 on the push block 64 first contacts the roller 12 and pushes it along the first dumping groove 45 until it dumps. Then, the first contact block 67 pushes the dumped roller 12 to move out of the first feed box 41 along the first discharge groove 44 and the ejection groove 65. At this time, the roller 12 is partially on the outside, completing the first press-fit push. Next, the telescopic cylinder 62 on the second feed box 51 is started, and the push block 64 drives the first contact block 67 to move, pushing the bearing rod 11 out of the second discharge groove 53 and the second dumping groove 54, passing through the avoidance groove of the fixed limiting block 68, entering the press-fit chamber 69 and passing through the roller 12, completing the second press-fit. After press-fitting, the bearing rod 11 props up the roller 12 and increases its diameter. The telescopic cylinder 62 on the first feed box 41 is started again to drive the pressed component to move in the pressing chamber 69. As the size of the roller 12 increases, it is restricted by the abutment groove and detached from the first contact block 67, and finally falls into the collection box 691 on the frame 2, realizing automatic material return and collection.
