Technical Field
[0001] The utility model belongs to the field of mechanical equipment, in particular to a tubular component grabbing device. Background Art
[0002] In the field of automobile manufacturing, there are a large number of tubular components that need to be transferred from the current operation link to the next operation link. However, due to the shape of the metal tube, it is difficult for ordinary grasping equipment to grasp it, and only a small part can be grasped during grasping. Once there are too many metal tubes to grasp, the grasping hand will have to increase the grasping pressure, and the metal tube will be deformed due to the grasping pressure, thereby damaging the metal tube. Patent No. 2022228832475 discloses a grasping device for metal tubular materials. However, the grasping device has the disadvantages of not being firm enough and not being easy to operate.

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model proposes a tubular device grabbing device. The specific technical solution is as follows:
[0004] A tubular component grasping device, a body of which is provided with a driving shaft, a first driving arm, a second driving arm, a first clamping arm and a second clamping arm, the first driving arm and the second driving arm respectively having a first guide groove and a second guide groove, the driving shaft having a first guide pin and a second guide pin, driven by the driving shaft, the first guide pin and the second guide pin respectively reciprocate in the first guide groove and the second guide groove, the first clamping arm and the second clamping arm are respectively movably connected to the first driving arm and the second driving arm through a first connecting pin and a second connecting pin, the first driving arm and the second driving arm respectively drive the first clamping arm and the second clamping arm to move, the driving shaft is provided with a first grabbing stick, the first clamping arm and the second clamping arm are respectively provided with a second grabbing stick and a third grabbing stick, the first grabbing stick, the second grabbing stick and the third grabbing stick are used for clamping the tubular component.
[0005] Preferably, the first grabbing rod, the second grabbing rod and the third grabbing rod can all rotate freely so that the clamped tubular device can rotate.
[0006] Preferably, the first clamping arm has a first limit pin, and the second clamping arm has a second limit pin, and the first limit pin and the second limit pin are used to limit the clamping angle formed by the first clamping arm and the second clamping arm.
[0007] Compared with the prior art, the beneficial effects of the utility model are as follows: under the drive of the driving shaft, the first guide pin and the second guide pin of the tubular device grasping device of the utility model reciprocate in the first guide groove and the second guide groove respectively, the first driving arm and the second driving arm drive the first clamping arm and the second clamping arm to move respectively, and the first grabbing stick provided by the driving shaft, the second grabbing stick provided by the first clamping arm, and the third grabbing stick provided by the second clamping arm are used to clamp the tubular device. The specific structure of the tubular device of this embodiment makes the grasping of the tubular device more convenient and efficient. At the same time, the first grabbing stick, the second grabbing stick, and the third grabbing stick can all rotate freely, which not only enables the tubular device grasping device of this embodiment to prevent slipping during the process of clamping the tubular device, but also prevents the surface of the tubular device from being damaged during the grasping process. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 This is a schematic diagram of the structure of the tubular component grabbing device of the utility model. DETAILED DESCRIPTION
[0009] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0010] like Figure 1 As shown, this embodiment provides a tubular device grasping device. Specifically, the tubular device grasping device of this embodiment is provided with a driving shaft 2, a first driving arm 3, a second driving arm 4, a first clamping arm 5 and a second clamping arm 6 in a body 1. The first driving arm 3 and the second driving arm 4 have a first guide groove 3.1 and a second guide groove 3.2 respectively. The driving shaft 2 has a first guide pin 2.1 and a second guide pin 2.2. Under the drive of the driving shaft 2, the first guide pin 2.1 and the second guide pin 2.2 are respectively moved in the first guide groove 3.1 and the second guide groove 3.2. The first clamping arm 5 and the second clamping arm 6 are respectively connected to the first driving arm 3 and the second driving arm 4 through the first connecting pin 5.1 and the second connecting pin 6.1, and the first driving arm 3 and the second driving arm 4 respectively drive the first clamping arm 5 and the second clamping arm 6 to move, and the driving shaft 2 is provided with a first grabbing stick 7, and the first clamping arm 5 and the second clamping arm 6 are respectively provided with a second grabbing stick 8 and a third grabbing stick 9, and the first grabbing stick 7, the second grabbing stick 8, and the third grabbing stick 9 are used to clamp the tubular device. The specific structure of the tubular device of this embodiment makes the grabbing of the tubular device more convenient and efficient.
[0011] The first grabbing rod 7, the second grabbing rod 8, and the third grabbing rod 9 can all rotate freely, so that the clamped tubular device can rotate. The first grabbing rod 7, the second grabbing rod 8, and the third grabbing rod 9 can all rotate freely, which not only prevents the tubular device grabbing device of this embodiment from slipping during the process of clamping the tubular device, but also prevents the surface of the tubular device from being damaged during the grasping process.
