The purpose of thus arranging the fixed support 2 and the sliding support 3 is: so that during operation, can lean on the spacing strip 19 respectively with two sets of work pieces (being the bar valve body) from the both sides of spacing strip 19 after tight, place on fixing support 2 and sliding support 3, so can reach the purpose of carrying out the location to the work piece and placing.

The inner side of the fixed support 2 and the inner side of the sliding support 3 are provided with a plurality of clamping sliding chutes 20 at intervals (refer to the attached figure 7 in the specification). Two groups of clamping devices 7 are arranged on the inner side of the fixed support 2 through a clamping sliding chute 20; the inner side of the sliding support 3 is provided with two sets of clamping devices 7 through clamping chutes 20 (see the description attached to fig. 1 and 2).

The clamping device 7 comprises a clamping adjusting seat 8, a tensioning screw 9, a tightening nut 10 and a clamping head 11 (see the description attached to fig. 3 and 4).

The inner side of the fixed support 2 and the inner side of the sliding support 3 are both provided with clamping adjusting seats 8 (refer to the attached figures 3 and 4 of the specification). One end of the clamping adjusting seat 8 is provided with a clamping sliding head 21 (see the attached figure 5 in the specification); the clamping adjusting seat 8 is connected with the corresponding clamping sliding chute 20 in a sliding manner through a clamping sliding head 21. The middle part of the other end of the clamping adjusting seat 8 is provided with a limiting bayonet 22 (see the attached figure 5 in the specification).

The inner side of the pressing slide block 13 above the pressing rod 17 is provided with a guide inclined surface 18 (see the description and the attached figure 6). The purpose of the guide ramps 18 is to: when the clamping head 11 moves upwards, the workpiece extrudes the pressing slide block 13 along the guide inclined plane 18 to enable the pressing slide block 13 to overcome the elasticity of the buffer spring 15 and move outwards, so that when the guide inclined plane 18 of the pressing slide block 13 is separated from the workpiece, the pressing slide block 13 can be kept in fit connection with the side surface of the workpiece through the inner side surface. Therefore, when the clamping device 7 clamps workpieces of different types, the pressing slide block 13 is attached to the side face of the workpiece, and the pressing rod 17 can finally press the workpiece.

When the assembling clamp seat of the rocker drill works, firstly, two groups of workpieces need to be respectively close to the limiting strips 19 from two sides of the limiting strips 19 and then are placed on the fixed support 2 and the sliding support 3.

The grippers 7 are then operated one by one, so that the grippers 7 clamp the workpiece on the fixed support 2 and the sliding support 3. The operation mode is that firstly, the tightening screw 9 of the clamp 7 is held by hand to drive the clamping head 11 to insert upwards on the workpiece, and during the process that the clamping head 11 moves upwards, the workpiece extrudes the pressing slide block 13 along the guide inclined plane 18 to move outwards after overcoming the elasticity of the buffer spring 15, so that when the guide inclined plane 18 of the pressing slide block 13 is separated from the workpiece, the pressing slide block 13 can be kept in fit connection with the side surface of the workpiece through the inner side surface. And then, continuously moving the clamping head 11 upwards to enable the pressure lever 17 to rotate downwards to the inside of the avoiding groove 16 when being pressed, continuously moving the clamping head 11 upwards, and after the pressure lever 17 completely moves to the upper part of the workpiece and loses support, rotating the pressure lever 17 to be in a horizontal state under the action of the elastic force of the torsion spring. And then, after the tensioning screw 9 is clamped into the limiting bayonet 22 of the corresponding clamping adjusting seat 8, the screwing nut 10 is screwed, so that the screwing nut 10 pulls down the tensioning screw 9 under the matching of the clamping adjusting seat 8, and finally, the workpiece is clamped and fixed through the pressure rod 17. Like this binding clasp 7 can be fixed the work piece clamp tightly on fixed bearing 2 and sliding support 3, and after the rocking arm bored the processing in completion stick hole, taken out the work piece of accomplishing the processing afterwards, this rocking arm bored the assembly holder and can get into next duty cycle.

In the process, the pressing slide block 13 is in clamping connection with the side face of the workpiece under the action of the elastic force of the buffer spring 15, so that the tensioning screw 9 can be relatively fixed with the workpiece through the bottom plate 12 and the pressing slide block 13, and the purpose of preventing the tensioning screw 9 from rotating along with the screwing nut 10 can be achieved in the process of screwing the screwing nut 10.

This assembly holder that rocking arm bored, compact structure, design benefit, during operation binding clasp 7 can follow both sides and press from both sides the valve body of stick valve tightly, and this assembly holder can press from both sides tightly fixedly to the valve body of two sets of stick valves simultaneously, has solved the current processing mode in stick valve stick hole from this and has had the problem that machining efficiency is low that the clamping work piece leads to repeatedly, is particularly suitable for the processing in stick valve stick hole.
