[0023] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:
[0024] The automatically closing floating clamp of the present invention includes a left opening and closing plate with a left pressure block and a right opening and closing plate with a right pressure block. Rotation of the left and right pressure blocks relative to the floating plate is achieved by operating the left operating end of the left opening and closing plate and the right operating end of the right opening and closing plate. The parts for operating the rotation of the opening and closing plates are located at the ends of the plates, facilitating the operation of the floating clamp for picking up and placing workpieces using other mechanized equipment. Furthermore, an elastic element is provided between the left and right opening and closing plates; releasing the left and right operating ends allows the left and right pressure blocks to move relative to the floating plate. The automatic return of the blocks limits the position above the workpiece, preventing it from detaching from the floating fixture. In particular, when the honing tool is withdrawn from the workpiece, it will not pull the workpiece out of the floating fixture. The floating fixture of this invention has a simple structure. The left and right pressure blocks can be controlled to limit the position above the workpiece by simply rotating and releasing the left and right opening and closing plates. Moreover, this floating fixture is composed of a purely mechanical structure and does not require external power. It can automatically close and lock the workpiece for floating processing, making it more stable, durable, easy to operate, and convenient for mechanized applications. Attached Figure Description

In one embodiment, the front connector, rear connector, left connector, and right connector are all screws. The screws are screwed into the floating adjustment blocks of the floating frame 2. The distance between the floating frame 2 and the front connector 42 / rear connector 43 / left support part 121 / right support part 122 is controlled by adjusting the screws, thereby controlling the range of motion of the floating plate 4.
[0041] The left opening and closing plate 5 has a left rotating end 51 and a left operating end 52 that are separated in the front and rear directions. The left opening and closing plate 5 is rotatably connected to the floating plate body 41 through the left rotating end 51 about a first axis extending in the up and down direction. The left operating end 52 is used to control the rotation of the left opening and closing plate 5 relative to the floating plate 4.

The right opening and closing plate 6 has a right rotating end 61 and a right operating end 62 that are separated in the front and rear directions. The right opening and closing plate 6 is rotatably connected to the floating plate body 41 through the right rotating end 61 about a second axis extending in the up and down direction. The right operating end 62 is used to control the rotation of the right opening and closing plate 6 relative to the floating plate 4. The right pressure block 63 is fixedly disposed on the right opening and closing plate 6. In one embodiment, the right operating end 61 extends from left to right. A rotating sleeve 7 that can rotate relative to the right operating end 61 is provided on the right operating end 61 for cooperating with other mechanical equipment to make the right opening and closing plate 6 rotate relative to the floating plate body 41.
[0042] In one embodiment, in the front-rear direction of the left opening and closing plate 5, the left pressing block 53 is disposed between the left rotating end 51 and the left operating end 52; in the front-rear direction of the right opening and closing plate 6, the right pressing block 63 is disposed between the right rotating end 61 and the right operating end 62. In the horizontal direction, both the left rotating end 51 and the right rotating end 61 are disposed within the floating frame 2, and both the left operating end 52 and the right operating end 62 are disposed outside the floating frame 2; in the vertical direction, both the left opening and closing plate 5 and the right opening and closing plate 6 are disposed between the floating frame 2 and the floating plate 4.
[0043] The elastic element 8 is disposed between the left opening plate 5 and the right opening plate 6. In one embodiment, the elastic element 8 is a tension spring, and the two ends of the tension spring are respectively connected to the left operating end 52 and the right operating end 62.
[0044] The floating fixture also includes a left meshing gear 54 and a right meshing gear 64. The left meshing gear 54 is positioned between the left opening plate 5 and the left pressure block 53. The left pressure block 53 is equipped with a left meshing gear shaft 55, and the left meshing gear 53 is fitted onto the left meshing gear shaft 55 and can rotate around it. The right meshing gear 64 is positioned between the right opening plate 6 and the right pressure block 63. The right pressure block 63 is equipped with a right meshing gear shaft 65, and the right meshing gear 64 is fitted onto the right meshing gear shaft 65 and can rotate around it. By setting the left meshing gear 54 and the right meshing gear 64, the horizontal rotation of the workpiece 10 can be restricted, improving the accuracy during honing.
[0045] The floating fixture also includes a enclosure section, which includes a front enclosure 91 and a rear enclosure 92. The enclosure section is fixedly mounted on the floating plate 4 to enclose the workpiece 10 together with the left pressure block 53, the right pressure block 63 and the floating plate body 41.
[0046] Floating clamps have closed and open states, such as Figure 1-2 As shown, when in the closed state, the left operating end 52 and the right operating end 62 are positioned close to each other, and the left pressure block 53 and the right pressure block 63 are positioned close to each other. The left pressure block 53, the right pressure block 63, the front enclosure 91, the rear enclosure 92, and the floating plate body 41 form a workpiece space, which is used to accommodate the workpiece 10. If the workpiece 10 is placed in the workpiece space, the left pressure block 53 and the right pressure block 63 together restrict the workpiece 10 from coming out from above, the floating plate body 41 supports the workpiece, and the front enclosure 91 and the rear enclosure... 92 restricts the forward and backward displacement of workpiece 10. Left meshing gear 54 and right meshing gear 64 engage workpiece 10 to prevent horizontal rotation. When transitioning from a closed to an open state, operating the left operating end 52 and right operating end 62 causes the left opening plate 5 to rotate clockwise around the first axis, with the left meshing gear 54 moving synchronously with the left pressure block 53. The right opening plate 6 rotates counterclockwise around the second axis, with the right meshing gear 64 moving synchronously with the right pressure block 63. The elastic element 8 extends under force. Figure 3 As shown, when in the open state, the left operating end 52 and the right operating end 62 are set apart, the left pressure block 53 and the right pressure block 63 are set apart, and the left meshing gear 54 and the right meshing gear 54 are also set apart. At this time, the workpiece 10 can be picked up and put down. When changing from the open state to the closed state, the left operating end 52 and the right operating end 62 are released. The elastic element 8 provides elastic force when changing from the open state to the closed state. The left opening and closing plate 5 rotates counterclockwise around the first axis, and the right opening and closing plate 6 rotates clockwise around the second axis.
