[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.
[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0028] See also Figures 1 to 6 , is a rotating clamping jaw structure of an embodiment of the present invention, comprising a bearing assembly 10, a rotating assembly 20 installed at one end of the bearing assembly 10, and a clamping jaw assembly 30 installed at the other end of the bearing assembly 10.
[0029] The bearing assembly 10 includes a first carrier plate 11 and a second carrier plate 12 which are arranged in parallel and spaced apart, a lifting plate 13 which is slidably connected between the first carrier plate 11 and the second carrier plate 12, a limiting cover 14 which is connected to one side of the lifting plate 13, and a cylinder 15 installed on one side of the first carrier plate 11; one end of the cylinder 15 is used to connect to the lifting plate 13 to drive the lifting plate 13 to achieve lifting and sliding between the first carrier plate 11 and the second carrier plate 12.
[0030] Specifically, a receiving chamber 16 is formed between the limiting cover 14 and the lifting plate 13 , and the receiving chamber 16 is used to receive one end of the clamping jaw assembly 30 , so as to facilitate the opening and closing action of the clamping jaw assembly 30 to be driven by the cylinder 15 .
[0031] In this embodiment, a slot-shaped photoelectric switch 17 is further disposed on one side of the first carrier plate 11 for locating the rotation angle of the rotating assembly 20 .
[0032] The rotating assembly 20 includes a motor 21 mounted on the first carrier plate 11, a coupling 22 coaxially connected to the rotor of the motor 21, and a positioning piece 23 mounted on one side of the coupling 22. The coupling 22 passes through the first carrier plate 11 and is connected to the clamping jaw assembly 30 downward, so that the motor 21 can drive the clamping jaw assembly 30 to rotate. Specifically, slots 220 are arranged at intervals on the side wall of the coupling 22, and the length direction of the slots 220 is consistent with the length direction of the coupling 22, and the slots 220 are used to match and connect the clamping jaw assembly 30.
[0033] In this embodiment, the positioning piece 23 is used to penetrate the notch of the slot-type photoelectric switch 17 to determine the number of rotations of the motor 21 and further determine the rotation angle of the entire clamping jaw assembly 30 .
[0034] The clamping jaw assembly 30 includes a bracket 31 rotatably mounted on the second carrier plate 12, a clamping jaw 32 hinged to the end of the bracket 31, a main shaft 33 that slides through the top of the bracket 31 and then hinges the clamping jaw 32, and rollers 34 mounted on opposite sides of the main shaft 33 away from the clamping jaw 32. The main shaft 33 is used to coaxially connect to the coupling 22 after being passed through the second carrier plate 12, and the roller 34 is connected to the main shaft 33 after passing through the slot 220 through the connecting rod 35, and the roller 34 is located inside the accommodating cavity 16 and rotates.
[0035] See also Figure 2 and Figure 3 In this embodiment, the connecting rod 35 is connected to the main shaft 33 after passing through the slot 220, so as to realize the coaxial connection between the main shaft 33 and the coupling 22. Furthermore, one end of the connecting rod 35 protruding beyond the slot 220 is used to connect the roller 34. It can be seen from this that through the coupling 22, the motor 21 can drive the entire clamping jaw assembly 30 to rotate at any angle. The height of the coupling 22 and the first carrier plate 11 is relatively fixed, and the cylinder 15 is used to drive the movement of the lifting plate 13 and the limiting cover 144, so that the main shaft 33 and the coupling 22 can slide relative to each other along the axis direction, and the extension and retraction of the main shaft 33 can drive the opening and closing of the clamping jaw 32.
[0036] Specifically, in this embodiment, the bracket 31 is arranged roughly in an "n" shape, and the clamping jaw 32 is a scissor-type clamping jaw. The clamping jaw 32 includes a first clamping plate 321 and a second clamping plate 322 that are hinged to each other, and the top ends of the first clamping plate 321 and the second clamping plate 322 are respectively hinged to the main shaft 33. The first clamping plate 321 and the second clamping plate 322 can be driven to move away from or closer to each other by the extension and contraction of the main shaft 33, so as to realize the opening and closing of the clamping jaw 32.
[0037] The above-mentioned rotating clamping jaw structure is compact and easy to use. The cylinder 15 is used to drive the main shaft 33 to extend and retract to realize the opening and closing of the clamping jaw 32. The motor 11 can also be used to drive the main shaft 33 to rotate to realize the rotation of the clamping jaw 32 at any angle, which can achieve precise clamping and greatly improve production efficiency.
[0038] 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.
[0039] 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.
