Description

Technical Field

[0001] The utility model belongs to the technical field of wheel spoke processing, in particular to a wheel spoke skeleton iron piece grabbing device. Background Art

[0002] The wheel hub is the metal skeleton of a car, such as a new energy vehicle tire. The wheel hub is the core component of the car tire, carrying the entire weight of the car through the wheel hub. Therefore, the performance of the wheel hub determines the safety of the car.

[0003] The structure of the wheel hub mainly includes the rim, spokes, offset and other structures. Among them, the spokes are the structure that fixedly connects the rim and the offset and other structures. As the supporting structure of the wheel hub, it is crucial to maintain the stability of the wheel hub structure.

[0004] During the spoke production process, the outer ends of the spoke skeleton are die-casted with iron caps to increase the spoke's structural stability. The iron caps are loaded onto a vibrating feeder and then picked up by a mechanical gripper and loaded onto a lathe for die-casting.

[0005] However, since the iron parts in Baotou are small workpieces with small volume, light texture and very high degree of special shape, it is more difficult to grasp the iron parts with small volume, light texture and high degree of special shape during the production process.

[0006] Specifically, traditional mechanical grippers and tools struggle to accurately grasp and load iron parts with these characteristics. Even when they can grasp, the gripping stability is limited, resulting in parts falling out due to a lack of stability. This results in the lathe being unable to fully grasp the mold, necessitating manual refilling. Specifically, the lathe must be completely filled with molds before it can complete the required number of iron parts required to form the spoke skeleton. Utility Model Content

[0007] Based on the above background, the purpose of the present invention is to provide a wheel spoke skeleton iron piece grabbing device.

[0008] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0009] A spoke skeleton ironwork grabbing device comprises a grabbing mechanical arm, on which a grabbing clamp mechanism is installed;

[0010] The material grabbing fixture mechanism includes a fixture frame installed on a material grabbing mechanical arm, and a plurality of material grabbing structures are installed at the bottom of the fixture frame;

[0011] The material grabbing structure includes a double-claw cylinder, a piston rod slide is fixedly installed at the end of the double-claw cylinder, the piston rod of the double-claw cylinder is slidably connected to the piston rod slide, and the piston rods of the double-claw cylinder are respectively installed with mutually cooperating material grabbing rods. During the material grabbing process, the material grabbing rods are clamped on both sides of the iron piece;

[0012] The material grabbing structure also includes a push rod pressed against the iron piece. After the iron piece is grabbed, the iron piece is pressed against by the push rod.

[0013] Preferably, the grabbing rod includes a mounting portion fixedly connected to the piston rod of the double-claw cylinder, the mounting portion is integrally formed with a grabbing portion, and the bottom of the grabbing portion is integrally formed at the top position of the mounting portion.

[0014] Preferably, the fixture frame is fixedly assembled with five grabbing structures distributed in a circular array;

[0015] The material grabbing structure is installed at the edge of the clamp frame.

[0024] The utility model has the following beneficial effects:

[0025] 1. During the iron work, when the double-claw cylinder is in operation, the two piston rods of the double-claw cylinder push the Z-shaped gripper rods against each other until they grab the pre-arranged iron pieces. Under the grip of the Z-shaped gripper rods, highly irregular iron pieces are clamped on both sides of the Z-shaped gripper rods. This method enables iron pieces to be grabbed in a more delicate and precise manner.

[0026] 2. When the Z-shaped grabbing rod grabs the iron piece, it will contact the arc structure of the iron piece through the supporting rod. Specifically, the supporting rod will contact the arc groove of the arc structure of the iron piece. Under the cooperation of the supporting rod's contact limit and the Z-shaped grabbing rod's clamping and grabbing, the iron piece with high degree of irregularity, small size and difficult to grab can be grabbed accurately and stably.

[0038] Example 1

[0039] like Figure 1-6 As shown, a spoke skeleton iron material grabbing device includes a material grabbing robot arm 201. The material grabbing robot arm 201 is a conventional workshop material grabbing production robot arm disclosed in the prior art.

[0040] In order to achieve the goal of grabbing small, light and highly shaped iron pieces, the grabbing robot arm 201 is equipped with a grabbing fixture mechanism 2. The specific structure of the grabbing fixture mechanism 2 is as follows:

[0041] The gripping fixture mechanism 2 includes a fixture frame 2 mounted on the gripping arm 201. The fixture frame 2 comprises a mounting base 21 fixedly mounted on the gripping arm 201, to which a mounting arm 22 is fixedly connected. Furthermore, a fixture base 23 (octagonal in cross-section and provided with several through-holes) is fixedly connected to the mounting arm 22. The double-claw cylinder described below is mounted at the bottom of the fixture base 23. A triangular rib is fixedly connected between the outer bottom of the mounting arm 22 and the mounting base. This rib provides increased stability for the longer mounting arm 22.

[0042] At the same time, a cushion block 221 is fixedly connected to the top of the inner end of the mounting arm 22 , and the cushion block 221 is fixedly mounted on the clamp seat 23 .

[0043] Five material grabbing structures 24 distributed in a circular array are installed at the bottom of the clamp frame 2 (distributed at the bottom edge of the clamp seat 23).

[0044] Specifically, the above-mentioned grabbing structure 24 includes a double-claw cylinder 241 (specifically, the bottom of the clamp seat 23 is fixedly assembled and connected with several cylinder seats 245, and the double-claw cylinder 241 is fixedly installed at the top position of the cylinder seat 245), and the end of the double-claw cylinder 241 (the end position of the cylinder barrel) is fixedly installed with a piston rod slide 242, and the piston rod 2411 of the double-claw cylinder 241 is slidably connected to the slide groove 2421 opened on the piston rod slide 242, and the piston rod 2411 of the double-claw cylinder 241 is respectively installed with grabbing rods 243 that cooperate with each other. During the grabbing process, the grabbing rods 243 are clamped on both sides of the iron piece B.

[0045] Specifically, the grabbing rod 243 includes a mounting portion fixedly connected to the piston rod of the double-claw cylinder 241. The mounting portion is integrally formed with a grabbing portion, and the bottom of the grabbing portion is integrally formed at the top of the mounting portion. That is, the grabbing rod 243 has a Z-shaped structure. During the grabbing process, when the double-claw cylinder 241 is operating, the two piston rods of the double-claw cylinder 241 push the Z-shaped grabbing rods 243 against each other until they grab the pre-regularly arranged iron pieces B. Under the Z-shaped grabbing rods 243, the highly irregular iron pieces B are clamped on both sides of the Z-shaped grabbing rods 243. This method allows for relatively precise and accurate grabbing of the iron pieces B. After being grabbed and placed on the lathe, the iron pieces B are die-cast onto the spokes A.

[0046] Example 2

[0047] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 1, the above-mentioned material grabbing structure 24 further includes a push rod 244 pressed against the iron piece B. After the iron piece B is grabbed, the iron piece B is pressed against by the push rod 244. Specifically, through the interference effect of the push rod 244, after the grabbing rod 243 of the Z-shaped structure grabs the iron piece B, the push rod 244 abuts against the arc structure of the iron piece B. Specifically, the push rod 244 abuts against the arc groove of the arc structure of the iron piece B. Under the cooperation of the interference limit of the push rod 244 and the clamping and grabbing of the grabbing rod 243 of the Z-shaped structure, the iron piece B with high irregularity, small size and difficult to grab can be grabbed in a precise and stable manner.

[0048] The specific shape of the push rod 244 is:

[0049] The push rod 244 includes a rod seat portion fixedly installed at the top position of the cylinder barrel of the double-claw cylinder 241, and an outwardly extended push rod 244 portion is integrally formed on the rod seat portion, and the push rod 244 portion abuts against the iron piece B.

[0050] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
