[0002] The main pump piston rod is actually a connecting component that supports the piston in the motion execution parts of oil cylinders, air cylinders, and hydraulic cylinders. It is a widely used part in industrial machinery, mainly for transmitting torque and bearing loads. During the production process of the main pump piston rod, the tool on the CNC machine tool will process the main pump piston rod.

[0003] The existing main pump piston rod is processed by a milling cutter. However, during the long processing process, since the tool body and the tool holder are fixed with bolts, when replacing the tool body, the operator needs to bend down and look up to observe the bolt position at the bottom of the tool holder, and then disassemble the tool body. This operation is troublesome and inconvenient to replace.

[0004] Therefore, we proposed a machine tool tool holder fixing structure for main pump piston rod processing in order to solve the above-mentioned problems. Utility Model Content

[0021] Example 1: Please refer to Figure 1 and Figure 2 A machine tool tool holder fixing structure for main pump piston rod processing includes a fixing structure 1, wherein the fixing structure 1 includes a tool holder 11 and a tool 12 arranged at the upper end of the tool holder 11, and a connecting rod 2 is arranged at the bottom end of the tool 12 and inside the top end of the tool holder 11.

[0022] The tool holder 11 includes a round rod 111 and a rod groove 114 opened at the top of the round rod 111, a positioning strip 115 is installed inside the rod groove 114, a plug hole 116 is opened at the top of the positioning strip 115, and the plug hole 116 is provided with two groups, the two groups of plug holes 116 are opened at the top of the positioning strip 115 in a diagonal direction, a limiting groove 117 is opened inside the plug hole 116 and on one side facing the other group of the plug holes 116, and a push strip 118 is slidably installed inside the limiting groove 117, and one end of the push strip 118 is A threaded hole B1182 is provided, a threaded hole B1182 is installed at one end of the push strip 118 and at the upper end of the threaded hole B1182, a threaded hole A113 is provided on the outer side of the round rod 111 and at the same height as the push strip 118, and the threaded hole A113 is aligned with the threaded hole B1182, a limiting hole 112 is provided in the upper half of the threaded hole A113, the internal thread of the threaded hole A113 is connected with a bolt 3, a threaded groove is provided on the inner side of the bent strip 1181, and the bent strip 1181 matches the limiting hole 112.

[0023] In this embodiment: hold the bar groove 21, insert the top end of the insertion bar 22 into the inside of the insertion hole 116, and position the installation of the connecting rod 2. The connecting rod 2 moves up inside the rod groove 114, and the top end of the insertion bar 22 with the inclined groove 23 is inserted between the inclined block 1183 and the insertion hole 116. After the threaded hole A113 is aligned with the threaded hole B1182, the bent bar 1181 is inserted into the inside of the limiting hole 112, and the bent bar 1181 protrudes on the outside of the round rod 111. The installer can observe the position of the bent bar 1181 to determine whether the connecting rod 2 is assembled in place. The bent bar 1181 is at the side end of the round rod 111 to avoid the operator bending over to observe.

[0024] Example 2: Please refer to Figure 3 and Figure 4 A ramp block 1183 is installed on the outer surface of the push bar 118 and on the side facing the insertion hole 116 , and a compression spring 1184 is installed between one side of the ramp block 1183 and the side of the insertion hole 116 facing the bent bar 1181 for pulling back the push bar 118 .

[0025] A groove 21 is formed at the top of the connecting rod 2, and an inserting strip 22 is installed inside the groove 21. There are two groups of inserting strips 22, which are installed diagonally on both sides of the bottom end of the groove 21. The width of the inserting strip 22 is smaller than the width of the insertion hole 116.

[0026] A bevel groove 23 is provided on the side away from each other of the two groups of the inserting strips 22, and the bevel groove 23 is located above the connecting rod 2. The bevel end of the bevel block 1183 has the same inclination as the bevel end of the bevel groove 23. The inserting strip 22 is inserted into the interior of the insertion hole 116, and one side of the bevel groove 23 contacts one side of the bevel block 1183, thereby pushing the bevel block 1183 and the pushing strip 118 to move.

[0027] The two groups of inserts 22 have threaded holes D25 on their sides away from each other. The outer surface of the connecting rod 2 has threaded holes C24 that are aligned with the threaded holes D25. The threaded ends of the bolts 3 can be threadedly connected into the threaded holes C24 and D25.

[0028] The threaded hole B1182 passes through the middle end of the push bar 118 and is aligned with the threaded hole C24 and the threaded hole D25, so that the threaded end of the bolt 3 can be threadedly connected from the inside of the threaded hole A113 and the threaded hole B1182 into the inside of the threaded hole C24 and the threaded hole D25.

[0029] In this embodiment: during the process of inserting the inserting strip 22 into the inside of the inserting hole 116, the inserting strip 22 will push the pushing strip 118 to move to one side of the limiting hole 112 through the inclined block 1183. After the threaded hole A113, the threaded hole B1182, the threaded hole C24 and the threaded hole D25 are aligned, the threaded end of the bolt 3 can be used to fix the connecting rod 2 and the fixed structure 1. Conversely, after the connecting rod 2 is pulled out, the compression spring 1184 can use its own restoring force to push back the inclined block 1183, so as to facilitate the installation of the next set of connecting rods 2 and cutters 12.

[0030] Working principle: the insert strip 22 is inserted into the inside of the socket 116 for positioning. As the connecting rod 2 moves upward, the connecting rod 2 is inserted into the inside of the socket 116. The insert strip 22 squeezes the push strip 118. When the bent strip 1181 protrudes from the inside of the limiting hole 112, the threaded hole A113, the threaded hole B1182, the threaded hole C24 and the threaded hole D25 are aligned. The tool holder 11 and the connecting rod 2 are fixed by the bolt 3. After the bolt 3 is reversed and removed, the connecting rod 2 can be disassembled, and the compression spring 1184 will push the compression spring 1184 back to facilitate the installation of the next set of connecting rods 2.
