Embodiment Construction
[0013] The reference signs in the drawings of the description include: outer jaw 1, inner jaw 2, positioning block 3, pressure ring 4, limit block 5, support plate 6, ejector rod 7, compression spring 8, frame 9.
[0014] Such as figure 1 As shown, an internal and external clamping device in this embodiment includes a frame 9 and an outer jaw 1 installed on the frame 9, the number of the outer jaws 1 is at least two, and also includes a frame mounted on the frame 9 The upper inner jaw 2. The inner jaws 2 are arranged between the outer jaws 1, and the frame 9 is provided with through holes, and the inner jaws 2 are slidably connected to the through holes. The clamping end of the inner jaw 2 is provided with a groove along its circumference and a pressure ring 4 which can press down the positioning block 3. The positioning block 3 is arranged in the groove, and a pressing ring 4 is provided between the positioning block 3 and the groove. The outside of the positioning block 3 ...

The invention discloses an internal and external clamping device which comprises a frame, at least two external clamping jaws and internal clamping jaws, wherein the external clamping jaws and the internal clamping jaws are mounted on the frame, and the internal clamping jaws are arranged between the external clamping jaws. Through holes are formed in the frame, the internal clamping jaws are slidably connected onto the through holes, grooves are circumferentially formed in clamping ends of the internal clamping jaws, positioning blocks are arranged in the grooves, pressure springs are arranged among the positioning blocks and the grooves, inclined surfaces are arranged on the outer sides of the positioning blocks and inclined towards driving ends of the internal clamping jaws, supporting plates are arranged at the driving ends of the internal clamping jaws, are connected with the frame through compression springs and can be abutted to driving ends of the external clamping jaws. A workpiece with holes is clamped by means of internal clamping and external clamping, two ends of the workpiece can be abutted by the frame and the positioning blocks, and side faces of the workpiece can be clamped by the external clamping jaws. The workpiece is more stably clamped, does not easily fall off from the clamping jaws and is not easily damaged, and operators are prevented from being injured by the crashing workpiece.
Description
technical field [0001] The invention belongs to the technical field of workpiece clamping. Background technique [0002] The current clamping mechanism is divided into inner clamping and outer clamping. The outer clamping is to clamp the outer surface of the workpiece. The inner clamping mechanism is to position and fix the workpiece by clamping the inner wall of the workpiece. Now the workpiece with holes can be It can be used for external clamping or internal clamping, and usually only one method is used for clamping. [0003] However, the stability of only using internal or external clamping is not high. Once the clamping is unstable, the workpiece will fall from the external or internal clamping jaws, which will not only damage the workpiece, but also easily smash the operator. hurt. Contents of the invention [0004] The invention provides an internal and external clamping device to solve the problem that only external clamping or internal clamping is used for workp...
