Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1-5, the high-precision multi-size positioning clamping cylinder is provided with a clamping seat body 1, a sealing bottom plate 7 is arranged at the bottom of the clamping seat body 1, pistons 2 are arranged in the clamping seat body 1 and the sealing bottom plate 7, a collet 3 is arranged on the upper portion of each piston 2, a plurality of positioning columns 4 are arranged on the pistons 2, springs 5 are sleeved on the positioning columns 4, the clamping seat body 1 is provided with a first ladder shaft 101 and a second ladder shaft 102, the first ladder shaft 101 is located on the upper portion of the second ladder shaft 102, lateral positioning screws 6 are arranged on the outer side wall of the first ladder shaft 101, and a cutter loosening hole 103 and a pressurizing hole 104 are formed in the side wall of the second ladder shaft 102.
Six positioning columns 4 are specifically arranged, and the six positioning columns 4 are distributed on the piston 2 in an annular array; the lateral positioning screws 6 are six, and the six lateral positioning screws 6 are distributed on the clamping seat body 1 in an annular array.
The piston 2, the sealing bottom plate 7 and the clamping seat body 1 are coaxially arranged; the pressurizing hole 104 is arranged obliquely above the cutter loosening hole 103.
The clamping seat body 1 is in threaded connection with the sealing bottom plate 7, the collet 3 is in threaded connection with the piston 2, and the positioning column 4 is in threaded connection with the piston 2.
The utility model discloses a theory of operation is: when the utility model is used, firstly, the piston 2 moves up in the clamping seat body 1 by ventilating from the tool loosening hole 103, in the ascending process of the piston 2, the positioning column 4 and the lateral positioning screw 6 respectively guide the piston 2 and the collet chuck to ensure the precision, the spring 5 compresses tightly and contracts, when the piston 2 is static, a tungsten steel bar is placed on the collet chuck 3, then the tool loosening hole 103 is deflated, the piston 2 moves downwards in the clamping seat body 1 in the deflated state, and under the action of the piston 2 and the spring 5, the front end of the cylinder claw 3 clamps the tungsten steel bar; in the clamping process, if the tungsten steel bar is small, the clamping force of the cylinder claw 3 on the secondary tungsten steel bar is insufficient, the pressurization hole 104 assists in air filling to enable the piston 2 to further move downwards, and the clamping force of the cylinder claw 3 is increased.
The above examples are provided for further illustration of the present invention, but do not limit the present invention to these specific embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be understood as being within the protection scope of the present invention.
