Clamping tooling for chambering rubber sealing element

The invention discloses a clamping tooling for chambering a rubber sealing element, which comprises a frame body; a first sliding groove is arranged on the inner side wall of the frame body; a first sliding block is slidably connected into the first sliding groove; a second sliding groove is arranged on the first sliding block; two clamping devices used for clamping the sealing element are arranged on one side of the second sliding groove; and an adjusting device for adjusting the distance between the two clamping devices is arranged between the two clamping devices. According to the clamping tooling for chambering the rubber sealing element provided by the invention, under driving of a first air cylinder, a driving rotating rod rotates around a placing table through a third connecting rod, so that a pressing plate is driven to downwards press the rubber sealing element or upwards move to loosen the rubber sealing element, and under driving of a first driving motor, a rack and the two clamping devices are dri
