[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but are not intended to limit the present invention.

[0040] Reference Figure 1-5 The utility model provides a quick clamping base, including a base 1, a lifting seat 2, a supporting platform 3, a lifting cylinder 4, a top support 5, a translation seat 6, a positioning assembly 9 and a slide seat 7.

[0041] The lifting seat 2 is arranged above the base 1. The supporting platform 3 is covered on the base 1 and its interior and the base 1 form a cavity for the lifting seat 2 to move. The supporting platform 3 is used to place the clamped object. The top of the supporting platform 3 is provided with a limit hole. The lifting cylinder 4 is connected to the base 1, and its lifting end passes through the lifting seat 2 and the limit hole in turn to connect with the top support member 5. The top support member 5 is preferably in the shape of an inverted frustum and has a protrusion 51 around its bottom. Several translation seats 6 are arranged around the top support member 5. In order to increase the force of the top support member 5 on the translation seat 6, an inclined surface corresponding to the top support member 5 is provided on the side of the translation seat 6 close to the top support member 5. One side of the translation seat 6 is slidably connected to the top of the lifting seat 2. The other side of the translation seat 6 is provided with a locking protrusion 61. The locking protrusion 61 extends from the limit hole. A cover body can be provided above the limit hole to store the locking protrusion 61 when not in use. When the supporting member 5 descends, it abuts against the translation seat 6 and causes the translation seat 6 to slide radially until the clamping protrusion 61 exceeds the radial range of the limiting hole. At this time, the clamping protrusion 61 abuts against the inner circle of the clamped object to achieve clamping.

[0042] In order to increase the force of the locking protrusion 61, a plurality of first return springs 22 are arranged between the lifting seat 2 and the base 1. As the supporting member 5 descends and pushes the translation seat 6 open, the protrusion 51 will contact the lifting seat 2 and drive it to move downward, so that the locking protrusion 61 abuts against the top of the supporting platform 3.

[0043] To reset the translation seat 6, a reset assembly 8 is provided between the translation seat 6 and the lifting seat 2. The reset assembly 8 includes a stopper 81 and a second reset spring 82. One side of the stopper 81 can be fixedly connected to the lifting seat 2. Alternatively, a fixing groove 21 can be provided at the top of the lifting seat 2. Then, one side of the stopper 81 can be inserted into the fixing groove 21 and fixed to the lifting seat 2 via a screw. The translation seat 6 can be adjusted by adjusting the position of the stopper 81 within the fixing groove 21. The translation seat 6 has an inner groove 62 radially defined at its bottom. The second reset spring 82 is located within the inner groove 62 and connects the inner groove 62 to the other side of the stopper 81.

[0044] The positioning assembly 9 is connected to the base 1 and is located on one side of the support platform 3. The positioning assembly 9 includes a connecting plate 91, a sliding rod 92, a positioning block 93, an adjustment plate 94, and an adjustment screw 95. The connecting plate 91 is used to connect to the base 1. One end of the sliding rod 92 is slidably connected to the connecting plate 91, and the positioning block 93 is slidably connected to the side wall of the sliding rod 92; wherein, the sliding direction of the positioning block 93 is perpendicular to the sliding direction of the sliding rod 92. The adjustment plate 94 is provided on one side of the connecting plate 91. One end of the adjustment screw 95 passes through the adjustment plate 94 and is threadedly connected to the side wall of the sliding rod 92. Rotating the adjustment screw 95 adjusts the sliding distance of the sliding rod 92. The base 1 is provided above the slide 7 and is slidably connected thereto.

[0045] Working principle: According to the position of the positioning component 9 on the side wall of the support platform 3, one side of the clamped object is pressed against the positioning block 93 and placed coaxially with the supporting member 5. Then the lifting cylinder 4 is started to contract so that the supporting member 5 presses against the translation seat 6 and contacts the inner circle of the clamped object and descends to fix the clamped object.
