DETAILED DESCRIPTION
[0025] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0027] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0028] See also Figure 1 and Figure 2A movable tooth handling gripper shown in a preferred embodiment of the present application includes a fixed bracket 1, a first gripper assembly 2 and at least two second gripper assemblies 3. The first gripper assembly 2 is arranged on one side of the fixed bracket 1 and is used to clamp and fix the reinforcing ribs on the back of the product. The at least two second gripper assemblies 3 are arranged on the other side of the fixed bracket 1. The second gripper assembly 3 includes a plurality of clamping rods 31 with accommodating grooves 311 at the ends and movable teeth 312 movably clamped in the accommodating grooves 311. The plurality of movable teeth 312 cooperate with each other to stably clamp the protruding slopes with different position angles on the back of different products.
[0029] Due to process errors during production, the angles and positions of the same clamping parts of different die-casting products may deviate, resulting in clamping gaps between the fixed-position clamps and the clamping parts of some die-casting products, making it impossible to fit tightly, which can easily cause the clamping of the die-casting products to loosen or even fall off, affecting the subsequent handling process.
[0030] Therefore, according to the solution of the embodiment of the utility model, a receiving groove 311 is provided on the clamping rod 31 of the second gripper assembly 3, and a movable tooth 312 is clamped in the receiving groove 311, so that when the clamping rod 31 of the second gripper assembly 3 clamps the protruding inclined road portion with a position angle deviation on the back of different products, the movable tooth 312 can move freely and fit on the side of the protruding inclined road, so that the protruding inclined road portion can be stably clamped with the cooperation of multiple movable teeth 312, thereby preventing the product from loosening or even falling off.
[0031] The following is a detailed description with specific embodiments:
[0032] See also Figure 1 , the at least two second gripper assemblies 3 are spaced apart along the straight line direction of the other side of the fixed bracket 1. In order to better clamp and fix the protruding ramp on the back of the die-casting product, it should be noted that the protruding ramp is a structure similar to a crossbeam, so at least two second gripper assemblies 3 are required to stably fix it. In this embodiment, there are two second gripper assemblies 3, which are respectively arranged at the two ends of the other side of the fixed bracket 1.
[0033] See also Figure 1 and Figure 2The second gripper assembly 3 also includes a second cylinder 32 and two second clamping jaws 33, and the second cylinder 32 is arranged on the other side of the fixed bracket 1. The two second clamping jaws 33 are arranged on the second cylinder 32 so as to be movable toward each other, and each second clamping jaw 33 is provided with at least one clamping rod 31. In this embodiment, each second clamping jaw 33 is provided with two clamping rods 31. On the same second gripper assembly 3, by cooperating with the four clamping rods 31 on the two second clamping jaws 33 to clamp the protruding ramp, the contact area and range of clamping can be increased, and the clamping is more stable. The movable tooth 312 is provided with a plurality of clamping small teeth 313 on the side facing away from the clamping rod 31. By providing a plurality of clamping small teeth 313 on the movable tooth 312, the friction between the movable tooth 312 and the protruding ramp can be increased, and the stability of clamping can also be further increased. It should be noted that the movable tooth 312 provided on the clamping rod 31 is made of a dynamic steel ball, and the movable tooth 312 is stuck in the receiving groove 311 and can be freely rotated to adjust the angle.
[0034] See also Figure 1 The first gripper assembly 2 includes a first cylinder 21, two first clamping jaws 22 and two clamping teeth 23. The first cylinder 21 is arranged on one side of the fixed bracket 1, and the two first clamping jaws 22 are arranged on the first cylinder 21 so as to be movable toward each other. The two clamping teeth 23 correspond to the two first clamping jaws 22 one by one, and are respectively arranged on the facing sides of the two first clamping jaws 22. It should be particularly noted that the first clamping jaw 22 is an L-shaped structure, and one side of the first clamping jaw 22 can drive the two clamping teeth 23 thereon to fit together, so as to be suitable for clamping smaller parts such as reinforcing ribs.
[0035] See also Figure 1 The fixed bracket 1 is a hollow structure. The design of the hollow structure of the fixed bracket 1 can reduce the weight of the entire device, thereby increasing the handling efficiency. The movable tooth handling gripper also includes a connecting member 11, which is arranged on the fixed bracket 1 and is used to connect the handling mechanism.
[0036] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0037] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
