Description

Technical Field

[0001] This utility model belongs to the technical field of machine tool processing and relates to a mold parting line detection device on a wheel hub production line. Background Technology

[0002] As the wheel hub manufacturing industry becomes increasingly automated, automated machining lines are becoming more widespread. Due to the manufacturing process of wheel hubs, there is a parting line. The physical parameters of the wheel hub at the parting line differ from those of other parts of the wheel hub. During processing, if the workpiece fixture acts on the parting line, it can easily cause deformation of the wheel hub. Therefore, it is necessary to avoid the parting line when clamping the workpiece.

[0003] When manually loading and unloading wheel hubs, the clamping angle can be adjusted freely to avoid the parting line. However, when producing wheel hubs on an automated production line, the position of the parting line cannot be determined, thus requiring an additional step of parting line detection. Utility Model Content

Each clamping jaw assembly includes a clamping block, a rotating shaft on the clamping block, and clamping wheels for clamping the wheel hub on the rotating shaft. Preferably, the clamping cylinder is a double-headed cylinder, with a pair of clamping jaw assemblies connected to the piston rods at both ends.

[0013] Alternatively, in the mold parting line detection device on the aforementioned wheel hub production line, one mold parting line detection camera is provided, and the rotation stroke of the rotary drive mechanism is not less than 360°.

[0014] In the aforementioned mold-closing line detection device on a wheel hub production line, a through-beam sensor for detecting the wheel hub position is installed on the material conveying frame at the material fixing mechanism.

Preferably, the limiting cylinder 16 is a double-headed cylinder, and a pair of limiting posts 17 are respectively connected to the piston rods at both ends. The lifting component includes several lifting cylinders 18 and a lifting plate 19 driven by the lifting cylinders 18. The lifting plate 19 moves up and down along the gap of the material conveying roller 3 and lifts the wheel hub. Both the limiting cylinders 16 and the lifting cylinders 18 are installed inside the material conveying frame 2.

[0026] A mold line detection camera 4 is used to capture the position of the mold line. The mold line detection camera 4 is set on one side of the material conveying frame 2. Specifically, a detection frame 20 is fixed on the frame 1, and the mold line detection camera 4 is mounted on the detection frame 20. To facilitate the mold line detection camera 4 in capturing the mold line, a detection light source 21 is provided on the inner side of the detection frame 20. Preferably, there are two mold line detection cameras 4, which are symmetrically arranged on the left and right sides of the frame 1. The rotation stroke of the rotary drive mechanism 7 is not less than 180°. By setting multiple mold line detection cameras 4, the rotation stroke of the rotary drive mechanism 7 can be reduced and the detection speed can be improved.

[0027] A detection auxiliary mechanism is provided, which rotates the hub to allow the mold parting line detection camera 4 to successfully capture the mold parting line. The detection auxiliary mechanism is mounted above the material conveying frame 2 and includes a rotating base plate 5. The rotating base plate 5 is driven to lift and rotate by a lifting drive mechanism 6 and a rotation drive mechanism 7, respectively. A material clamp 9 driven by a clamp drive mechanism 8 is provided on the rotating base plate 5. In this embodiment, the driving structures are: the lifting drive mechanism 6 is a servo lifting motor, the rotation drive mechanism 7 is a servo rotation motor, and the clamp drive mechanism 8 is a clamp cylinder. In this invention, other alternative mechanisms in the art can also be used for the above-mentioned driving mechanisms; for example, the lifting drive mechanism 6 is a hydraulic push rod, the rotation drive mechanism 7 is a rotary cylinder, and the clamp drive mechanism 8 is an electric clamp. Specific installation methods for each driving structure are described below. The following is a description of the material clamping fixture 9: A first mounting plate 10 is fixed on the frame 1. The servo lifting motor is mounted on the first mounting plate 10. A second mounting plate 11 connected to the servo lifting motor execution unit is located below the first mounting plate 10. The second mounting plate 11 slides on the first mounting plate 10 via several guide rods 12. The servo rotary motor is mounted on the second mounting plate 11. The rotating base plate 5 is located below the second mounting plate 11 and connected to the servo rotary motor execution unit. The specific structure of the material clamping fixture 9 is as follows: Several pairs of clamping cylinder-driven gripper assemblies are slidably arranged at the bottom of the rotating base plate 5. Each gripper assembly includes a clamping block 13, a rotating shaft 14 is provided on the clamping block 13, and a clamping wheel 15 with a clamping hub is provided on the rotating shaft 14.

[0028] Through-beam sensor 22: The material conveying frame 2 at the material fixing mechanism is equipped with an through-beam sensor 22 for detecting the position of the wheel hub.

[0029] The specific working process of this embodiment is as follows:

[0030] The hub is placed on the material conveying roller 3 of the material conveying frame 2 at any angle and moves forward with the material conveying roller 3. When the through-beam sensor 22 detects that the hub has entered the detection area, the material conveying roller 3 stops conveying. The limit cylinder 16 drives the limit post 17 to move towards the hub and pushes the hub to the set position. The lifting cylinder 18 drives the lifting plate 19 to move upward and lift the hub away from the material conveying roller 3. The servo lifting motor drives the second mounting plate 11, together with the servo rotary motor, the rotating base plate 5 and the material clamp 9, to move downward to the set position. The clamp cylinder drives the gripper assembly to move inward and clamp. The hub 15 is tightened, and the limiting post 17 and the lifting plate 19 are reset (the limiting post 17 can also be reset after the hub is lifted) so that the hub can rotate freely. The light source and the mold parting line detection camera 4 are started. The servo rotary motor drives the rotating base plate 5, together with the clamping drive mechanism 8, the material clamping fixture 9 and the hub to rotate. When the mold parting line detection camera 4 detects the mold parting line, the rotation stops. The lifting cylinder 18 drives the lifting plate 19 to move upward to support the hub. The detection auxiliary mechanism is reset. The limiting cylinder 16 drives the limiting post 17 to move towards the hub and fix the hub. The hub moves forward with the material conveyor 2 into the machine tool.
