[0009] Further, the station block is in a V-shaped structure, the bending angle of the station block is opposite to the shaft end of the hydraulic cylinder, and flexible pads are arranged on both side surfaces of the station block and the end surface of the pressure block.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0021] Referring to Figures 1 - 3 An embodiment of the present invention discloses a two-way clamping tooling for a shaft member, including a tooling base 1. Specifically, there are two mounting corners 11 and two working corners 12 symmetrically on the upper end of the tooling base 1. A pipe-laying channel 13 is also opened between the mounting corner 11 and the working corner 12 of the tooling base 1. The pipe-laying channel 13 is used to provide an installation space for the oil pipe.
[0022] A hydraulic cylinder 2 is fixedly installed on the mounting corner 11. A pressing block 21 is arranged at the shaft end of the hydraulic cylinder 2. A working block 3 is placed inside the working corner 12. A locking structure 4 is arranged between the tooling base 1 and the working block 3. That is to say, two hydraulic cylinders 2 and two working blocks 3 are provided in the present invention. Such a setting is used for clamping and fixing two shaft rods.
[0023] In some embodiments, the working block 3 in the present invention has a V-shaped structure. The bending angle of the working block 3 faces the shaft end of the hydraulic cylinder 2. Flexible pads 5 are arranged on both side surfaces of the working block 3 and the end surface of the pressing block 21. Preferably, the flexible pad 5 in this embodiment is set as a rubber pad to avoid hard contact between the pressing block 21 and the working block 3 and the shaft rod, resulting in problems such as surface damage.
[0024] During specific work, the shaft rod is placed on the working block 3. At this time, both ends of the shaft rod protrude from both sides of the working block 3. At this time, processing operations can be performed on both ends of the shaft rod to form a two-way working clamping method. In addition, the design of two hydraulic cylinders 2 can realize clamping of two shaft rods at one time, effectively improving the processing efficiency.
[0025] Furthermore, in this embodiment, the locking structure 4 includes an L-shaped channel 41 opened inside the tooling base 1. One end of the L-shaped channel 41 extends to the side of the working block 1, and the other end extends to the inclined surface of the mounting corner 11. It should be noted that the L-shaped channel 41 is set as a linear groove on the inclined surface of the mounting corner 11. A U-shaped locking rod 42 is slidably connected inside the L-shaped channel 41. Among them, a spring 43 is arranged between the U-shaped locking rod 42 and the L-shaped channel 41.
[0026] On the basis of the above embodiments, in this embodiment, a first guide post 44 is fixed on the outer side surface of the U-shaped lock rod 42, a second guide post 45 is fixedly installed on the inner side of the upper end of the L-shaped channel 41, and both ends of the spring 43 are sleeved between the first guide post 44 and the second guide post 45.
[0027] In a preferred embodiment, both the first guide post 44 and the second guide post 45 can be set as bolts. By using the first guide post 44 and the second guide post 45 to support and guide the spring 43, the convenient installation of the spring 43 can be realized, and the assembly convenience can be improved.
[0028] In order to be adapted to the U-shaped lock rod 42, in this embodiment, an L-shaped lock groove 31 is opened at the back end of the station block 3, and the bent part at the upper end of the U-shaped lock rod 42 slides and is clamped in the L-shaped lock groove 31. Of course, in this embodiment, the L-shaped lock groove 31 located at the lower end of the station block 3 is also set as a slotted groove to facilitate the sliding of the U-shaped lock rod 42.
[0029] Of course, in order to ensure the installation stability of the station block 3, in this embodiment, a plurality of positioning holes 14 are opened on the end surface of the station angle 12, and a positioning rod 32 adapted to the positioning holes 14 is fixedly installed at the back end of the station block 3.
[0030] During specific connection, the corresponding station block 3 can be selected according to the diameter of the shaft rod to be processed. First, install the U-shaped lock rod 42 to avoid the L-shaped lock groove 31, insert the positioning rod 32 at the bottom of the station block 3 into the positioning holes 14 on the station angle 12 inside the positioning holes 14. Thereafter, the pressure on the U-shaped lock rod 42 can be released. Under the pulling force of the spring 43, the U-shaped lock rod 42 resets and is clamped in the L-shaped lock groove 31 at the bottom of the station block 3, and the clamping and positioning of the station block 3 can be completed. On the contrary, the unlocking of the station block 3 can be realized. The operation is simple and convenient, and the assembly and replacement efficiency of the station block 3 can be effectively improved.
[0031] In addition, in this embodiment, an oil pipe 15 located above the pipe laying channel 13 is connected to the interface of the hydraulic cylinder 2. The design purpose of adopting this structure can realize the convenient pipe laying and connection of the oil pipe 15 for the two hydraulic cylinders 2, and further optimize the overall applicability of this tooling.
[0032] In summary, in the present utility model, by using the station block 3 to support the shaft rod, the two sides of the shaft rod can be exposed to form two processing stations at both ends of the shaft rod. Secondly, by using the cooperation of the two hydraulic cylinders 2 and the two station blocks 3, the clamping of the two shaft rods can be realized at one time, effectively improving the processing efficiency. Secondly, in the present utility model, the station block 3 is connected and positioned by the locking structure 4, so as to conveniently replace the corresponding station block 3 according to the diameter of the shaft rod to be processed. The overall structure design is simple, and the convenience of the shaft rod processing operation is optimized.
