Therefore, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0019] In the present application, unless otherwise specifically defined and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0020] The inventor finds that the current holding clamp jaw devices only have two local jaws for clamping the heat preservation cylinder, which is not easy to accurately find the center of the heat preservation barrel, realize accurate holding and clamping, and is easy to damage the heat preservation barrel. Therefore, a holding clamp jaw that can adaptively find the center is needed to solve the above problems.

[0021] As shown in Figure 1 , the utility model embodiment provides a holding clamp jaw device, which at least comprises: two jaw groups 1 and two jaw group supports 2; each jaw group support 2 is used for axially movably mounting each jaw group 1, it can be understood that one end of one jaw group support 2 is used for axially movably mounting one jaw group 1, that is, the jaw group support 2 and the jaw group 1 one-to-one correspondence. The jaw group support 2 can be used to realize the action of clamping and loosening. Further, each jaw group 1 contains two axially movably mounted jaws 11, as shown in Figure 1 , two ends of each jaw group 1 are axially movably mounted with one jaw 11 respectively. The specific use process of the holding clamp jaw device is as follows:

[0022] Step 1) In the case of needing to use the holding clamp jaw device to hold and clamp the heat field heat preservation barrel, start the holding clamp jaw device, and open the jaw group support 2 to a certain size / angle to adapt to the diameter of the heat preservation cylinder.

[0023] Step 2) Drive the jaw group support 2 forward to make the heat preservation cylinder in the center position of the four jaws 11.

[0024] Step 3) Drive the jaw group support 2 to close to clamp the heat preservation cylinder.

[0025] The holding clamp jaw device provided by the embodiment of the utility model has four jaws, so that the holding and clamping is more stable; and when holding and clamping the heat preservation cylinder, the four jaws can be adjusted by self-rotation and overall rotation to find the center of the heat preservation cylinder and clamp the heat preservation cylinder, avoiding the situation that only two local jaws clamp and damage the heat preservation cylinder.

[0026] Optionally, as shown in Figure 1 , when the four jaws 11 contact the heat preservation cylinder, each jaw 11 can rotate independently, that is, the four jaws 11 can select independent rotation to change the opening angle, such as one activity and the other three inactivity; or, the two jaws 11 in each jaw group 1 can rotate simultaneously, that is, the four jaws 11 can rotate simultaneously to change the opening angle, such as the two jaws 11 in one jaw group 1 can be active, and the two jaws 11 in the other jaw group 1 can be inactivity; or, the four jaws 11 in the two jaw groups 1 can rotate simultaneously to ensure that the four jaws 11 can adaptively and simultaneously clamp the heat preservation cylinder.

[0027] Optionally, asFigure 1 As shown in the figure, each jaw group 1 is axially movably connected with the jaw group support 2 through a common shaft 3. For example, the common shaft 3 can be connected and installed with the middle part of the jaw group 1, so that each jaw group 1 has a certain rotation angle.

[0028] Optionally, as shown in the figure, each jaw 11 is axially movably connected with the jaw group 1 through a jaw shaft 4. For example, the jaw shaft 4 can be connected and installed with the middle part of the jaw 11, so that each jaw 11 can freely rotate a certain angle around its own jaw shaft 4. Figure 1

[0029] Optionally, the clamping jaw device can further comprise a servo motor assembly for driving the jaw group support 2 to realize the clamping and loosening action. For example, in the case of clamping the heat field insulation barrel by using the clamping jaw device, the servo motor assembly is first started to rotate to drive the jaw group support 2 to realize the clamping and loosening action. Further, the servo motor assembly can also be used to adjust the size of the clamping force. Still further, the servo motor assembly can also be used to control the planar positioning accuracy of the jaw 11 in order to clamp the insulation barrel.

[0030] It should be noted that in the embodiment of the present application, the insulation barrel can be picked up and placed in the corresponding position by the clamping jaw device, and the servo motor assembly is started again to control the loosening of the jaw group support 2, and then the whole clamping process is completed.

[0031] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can easily think of changes or replacement technical solutions within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.​
