[0022] The present invention is further described in detail below through the accompanying drawings and specific implementation methods.

[0023] Embodiment 1:

[0024] like Figure 3-5As shown, the utility model provides a novel clamping mechanism, which includes a turning part 1, a supporting body 2, a main shaft 201 and a transmission assembly.

[0025] The flip part 1 is hinged on the support body 2, and the support body 2 is fixed to the end of the main shaft 201. The main shaft 201 and the linear moving part 401 of the transmission assembly are installed in a sliding fit so as to be able to slide relatively along the axial direction and rotate synchronously.

[0026] A first bearing seat 403 is mounted on the linear moving part 401 through a first bearing 402. Two first connecting rods 404 extending radially outward are arranged on the first bearing seat 403. The two first connecting rods 404 are respectively connected to a first cylinder 5. The first cylinder 5 can drive the first bearing seat 403 to drive the linear moving part 401 to move forward and backward.

[0027] A second bearing seat 602 is installed on the side of the main shaft 201 away from the support body 2 through a second bearing 601, and the first cylinder 5 is fixedly installed relative to the second bearing seat 602 through a connecting plate 11. Two second connecting rods 603 extending radially outward are arranged on the second bearing seat 602, and the two second connecting rods 603 are used to connect to a second cylinder 7 respectively. The second cylinder 7 can drive the second bearing seat 602 to drive the main shaft 201 and the first cylinder 5 to move forward and backward.

[0028] The two first connecting rods 404 are symmetrically arranged on the left and right sides of the central axis of the main shaft 201; the two second connecting rods 603 are symmetrically arranged on the left and right sides of the central axis of the main shaft 201. The first connecting rod 404 and the second connecting rod 603 are staggered. Thus, the two first cylinders 5 can be arranged above the two second cylinders 7, and the overall structure is relatively compact.

[0029] A sliding shaft hole 201b is provided at the end of the main shaft 201 away from the support body 2. The sliding shaft hole 201b is used to insert the power output shaft of the rotating motor 70. The power output shaft is installed in a sliding fit with the main shaft 201 so as to slide relative to each other in the axial direction and rotate synchronously. The sliding shaft hole 201b is a non-circular hole, such as a square hole, a hole with a keyway or a spline hole. The rotating motor can drive the main shaft 201 to rotate, thereby driving the support body 2 and the flip part 1 to rotate together. When the support body 2 and the flip part 1 rotate, since the main shaft 201 and the linear moving part 401 are connected to the second bearing seat 602 and the first bearing seat 403 through the second bearing 601 and the first bearing 402 respectively, the second bearing seat 602 and the first bearing seat 403 do not rotate together, but remain relatively stationary with the second cylinder 7 and the first cylinder 5.

[0030] A plug hole 100 is provided at the end of the first connecting rod 404 and the second connecting rod 603 . The plug hole 100 is used to insert a plug plate 101 . The plug plate 101 is used to be screwed and fixed on the cylinder arm of the first cylinder 5 or the second cylinder 7 .

[0031] The transmission assembly also includes a connecting plate 801 and a first shaft 802 and a second shaft 803 located at both ends of the connecting plate 801; one of the linear moving part 401 and the flipping part 1 is provided with a slide groove 804, and the other is provided with an axial hole, and one of the first shaft 802 and the second shaft 803 is fixedly arranged in the axial hole, and the other is arranged in the slide groove 804. In one embodiment of the utility model, the linear moving part 401 includes a sleeve part 401a sleeved on the main shaft 201 and a vertical plate 401b fixedly connected to the sleeve part 401a, and the sleeve part 401a is connected to the main shaft 201 by a key and a keyway. The slide groove 804 is arranged on the vertical plate 401b, and the axial hole is arranged on the flipping body 1.

[0032] A pressing portion 9 that can be lifted or pressed down is provided on one side of the support body 2 , and the pressing portion 9 is fixed to the flip portion 1 .

[0033] By adopting the above technical scheme, the novel clamping mechanism of the utility model changes the existing structure of pushing and pulling the fork-shaped shifting block driven by a single cylinder, and instead installs the first bearing seat 403 on the linear moving part 401 through the first bearing 402, and the first bearing seat 403 is provided with two first connecting rods 404 extending radially outward, and the two first connecting rods 404 are respectively connected to a first cylinder 5; the second bearing seat 602 is installed on the main shaft 201 through the second bearing 601, and the second bearing seat 602 is provided with two second connecting rods 603 extending radially outward, and the two second connecting rods 603 are respectively connected to a second cylinder 7, so that the overall structure is subjected to more balanced force during use, effectively improving the service life of the clamping mechanism and reducing the failure rate.

[0034] Embodiment 2:

[0035] like Figure 6-8 As shown, the difference between this embodiment and the first embodiment is that a first connecting rod 404 is provided on the first bearing seat 403 for connecting to a first cylinder 5, and a second connecting rod 603 is provided on the second bearing seat 602 for connecting to a second cylinder 7.

[0036] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention of the utility model.
