[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 4As shown, the utility model is a clamping device for double fork processing, including a base plate 1, a fixed V-shaped member 2, a sliding V-shaped member 3, a cylindrical clamping block 4, a cylindrical positioning block 5 and a fixed plate 7 with a push rod 6, wherein the base plate 1 is provided with a plurality of through holes, some of which can be used in conjunction with fixing bolts 8 to connect and install the fixed V-shaped member 2, the cylindrical positioning block 5 and the fixed plate 7 with the push rod 6, while some of the holes are used for hanging ring connection, which can facilitate upper and lower tooling by connecting the hanging rings. The top design of the cylindrical clamping block 4 is also designed with a hanging ring 40 for cooperation, and some of the holes can be connected to the work table of the machining center through connecting parts to position the machining position of the utility model.

[0022] Another thing to note about the base plate 1 is that a groove 9 is designed and formed on the top of the base plate 1, and the groove 9 is a through-type groove designed for a straight line, which can assist in the assembly and fixation of the fixed V-shaped part 2, the sliding V-shaped part 3, the cylindrical positioning block 5 and the fixed plate 7 based on the same straight line direction, thereby ensuring that the sliding V-shaped part 3 can stably reinforce the double fork on the same straight line when being pushed and pressurized, avoiding the situation where the angle deviation causes shaking in subsequent processing, etc. Based on this, the bottom of the fixed V-shaped part 2, the sliding V-shaped part 3, the cylindrical positioning block 5 and the fixed plate 7 are also designed with a positioning boss 100 to be embedded in the groove 9, in order to further ensure that the four are located on the same straight line for alignment and assembly. It can be extended to explain that the fixed V-shaped part 2, the cylindrical positioning block 5 and the fixed plate 7 are all fixed to the base plate 1 by fixing bolts 8, and only the sliding V-shaped part 3 is movably assembled on the base plate 1. The fixed V-shaped member 2, the sliding V-shaped member 3, the cylindrical positioning block 5 and the fixed plate 7 are sequentially arranged on the bottom plate 1, so that the fixed plate 7 with the push rod 6 can realize the working control of the sliding V-shaped member 3 arranged in front of it, specifically, by rotating the push rod 6 counterclockwise or clockwise to retreat or pressurize the sliding V-shaped member 3, thereby realizing the angular fixation of the double fork arranged between the fixed V-shaped member 2 and the sliding V-shaped member 3. In order to realize the angular fixation, the fixed V-shaped member 2 and the sliding V-shaped member 3 are designed and formed with a positioning groove 20 for auxiliary installation of the double fork, and the cross-sectional structure of the positioning groove 20 is a trapezoidal design or a V-shaped design, so as to realize the fixation of the double fork arranged between the two.

[0023] In addition to angular fixation, the utility model is also provided with a cylindrical positioning block 5 and a cylindrical clamping block 4 to radially position the double fork. The cylindrical clamping block 4 is movably connected to the top of the cylindrical positioning block 5 through a clamping bolt 10. After the cylindrical clamping block 4 is connected to the cylindrical positioning block 5, the double fork is positioned and wrapped by the two to achieve positioning assembly. It can be noted that the cylindrical positioning block 5 and the cylindrical clamping block 4 are both designed in a U-shaped structure. After the two are connected and assembled, they can wrap and lock the middle double fork. Such a design can further strengthen the double fork.

[0024] Based on the cooperation between the fixed V-shaped member 2 and the sliding V-shaped member 3, the cylindrical positioning block 5 and the cylindrical clamping block 4, the double fork to be processed can be locked in six directions, namely front and back, left and right, and up and down. Such a design can ensure its stability during the processing, prevent shaking, and avoid affecting the high precision and yield rate of the processing. In addition, the utility model is also simple to disassemble and assemble the workpiece, which can improve a certain efficiency.

[0025] Regarding the cylindrical positioning block 5, it can be further explained that an internal threaded countersunk hole is provided on the cylindrical positioning block 5 for threaded connection of the clamping bolt 10 of the cylindrical clamping block 4, and the positioning stability of the double fork located between the two can be controlled by adjusting the tightness of the nut of the clamping bolt 10.

[0026] The fixing plate 7 is also provided with an internal threaded through hole, which is used to connect the push rod 6, so the outer wall surface of the push rod 6 is correspondingly formed with an external thread to allow it to be movably assembled on the fixing plate 7 through a threaded connection. The push rod 6 based on the threaded connection can obtain a relatively linear movement when the control sliding V-shaped member 3 is moved, pressurized or retreated, and can achieve a steady advancement effect when positioning and assembling the double fork to avoid overtightening.

[0027] The front end of the push rod 6 is embedded in the countersunk hole of the sliding V-shaped part 3, and the end is provided with a through hole 61 for the handle to be inserted and matched, wherein the through hole 61 cooperates with the detachable handle to achieve installation and use, avoiding unnecessary parts and unnecessary volume affecting the tool path during processing, thereby causing the accident of tool collision.

[0028] When the utility model is in use, a bottom plate 1 provided with a fixed V-shaped member 2, a cylindrical positioning block 5, a sliding V-shaped member 3 and a fixed plate 7 with a push rod 6 is fixedly mounted on a work surface of a machining center, and then the double fork is placed between the fixed V-shaped member 2 and the sliding V-shaped member 3, and then the sliding V-shaped member 3 is pushed by rotating the push rod 6 to angularly align the double fork in the fixed V-shaped member 2 and the sliding V-shaped member 3. At this time, the double fork is still located above the cylindrical positioning block 5, and finally, the cylindrical clamping block 4 is installed on the upper side of the cylindrical positioning block 5 by means of the clamping bolt 10, so that the double fork can be locked in position and assembled in a positioned manner, and tool alignment processing can be performed. Thanks to the threaded connection adopted for the connection, the assembly and disassembly is convenient and quick, and the connection stability is also excellent, and it is not easy to get loose.

[0029] The utility model provides a double-fork processing clamping device which is convenient to operate, accurate in positioning, stable and reliable through reasonable structural design.
