[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. This kind of tooling fixture and tooling tool are used in cooperation between a first chuck, a second chuck, a swing block, a transmission shaft and a connecting rod. The rotating shaft is rotated to control the swing block to swing. When the swing block swings, the transmission shaft and the connecting rod at both ends respectively drive the first chuck and the second chuck to swing synchronously. When the first chuck and the second chuck swing, the adjustment blocks on their inner sides will move in the same direction to clamp the workpiece. When the rotating shaft is reversed, the ends of the first chuck and the second chuck will be stretched outward, thereby loosening the clamped workpiece, thereby achieving the purpose of facilitating clamping and fixing.

DETAILED DESCRIPTION

[0022] 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.

[0023] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0024] A tooling fixture comprises a first chuck 1 and a second chuck 2, wherein an adjusting block 3 is movably mounted on the inner wall of the same side of the first chuck 1 and the second chuck 2, two ends of the top of one side of a mounting plate 10 are movably connected to the first chuck 1 and the second chuck 2 through a rotating rod, a rotating shaft 11 is movably mounted on the bottom of the other side of the mounting plate 10, a swing block 12 is fixedly mounted on the top of the rotating shaft 11 through the mounting plate 10, a transmission shaft 13 is movably mounted on the top of the left side of the swing block 12, a connecting rod 14 is movably mounted on the top of the right side of the swing block 12, the other end of the transmission shaft 13 is movably connected to a second set of rods 9, and the other end of the connecting rod 14 is movably connected to a first set of rods 8; a first set of rods 8 is fixedly mounted on the top of the first chuck 1 away from the fixed block 401, and a second set of rods 9 is fixedly mounted on the top of the second chuck 2 close to the first set of rods 8;

[0025] In this embodiment, when in use, the rotating shaft 11 is rotated, and the rotating shaft 11 controls the swing block 12 to swing. When the swing block 12 swings, the transmission shaft 13 and the connecting rod 14 at both ends respectively drive the first chuck 1 and the second chuck 2 to swing synchronously. When the first chuck 1 and the second chuck 2 swing, the adjustment block 3 on the inner side thereof will move in the same direction to clamp the workpiece. When the rotating shaft 11 is reversed, the ends of the first chuck 1 and the second chuck 2 will be stretched outward, thereby loosening the clamped workpiece, thereby achieving the purpose of facilitating clamping and fixing.

[0026] like Figure 2 and Figure 4 As shown, an adjustment mechanism 4 is arranged between the first chuck 1, the second chuck 2 and the adjustment block 3, and the adjustment mechanism 4 includes a fixed block 401, a threaded rod 402 and a threaded groove 403. The fixed blocks 401 are fixedly installed on the outer sides of the same-direction ends of the two adjustment blocks 3, and the threaded rod 402 is movably installed in the middle of the fixed block 401. A threaded groove 403 is provided inwardly at the middle of one end of the first chuck 1 and the second chuck 2 close to the fixed block 401, and the threaded rod 402 is threadedly connected with the threaded groove 403. The end of the threaded rod 402 away from the threaded groove 403 passes through the fixed block 401 and is fixedly installed with an adjustment button 5;

[0027] In this embodiment, when the workpiece to be clamped is longer, the adjusting knob 5 is twisted, and the adjusting knob 5 controls the threaded rod 402 to rotate and exit along the inside of the thread groove 403. When the threaded rod 402 retreats, the fixed block 401 is controlled to move synchronously, thereby causing the adjusting block 3 on the inner side of the first chuck 1 and the second chuck 2 to slide outward, so that the longer workpiece can be clamped in the middle position, thereby achieving the purpose of easy adjustment.

[0028] like Figure 2 As shown, a rod groove 6 is penetrated through the middle of the adjustment block 3, and a guide rod 7 is fixedly installed on one end of the first clamp 1 and the second clamp 2 close to the rod groove 6, and the guide rod 7 is movably connected to the rod groove 6;

[0029] In this embodiment, when the adjustment block 3 is adjusted and moved, the guide rod 7 at one end of the first chuck 1 and the second chuck 2 close to the adjustment block 3 will slide and guide along the rod groove 6 opened in the middle of the adjustment block 3, and at the same time can support the adjustment block 3, thereby improving the structural stability.

[0030] like Figure 1 As shown, a swing arm 15 is fixedly installed on one side of the bottom end of the rotating shaft 11, and a connector 16 is fixedly installed on the bottom end of the other side of the swing arm 15;

[0031] In this embodiment, a swing arm 15 is provided on one side of the bottom end of the rotating shaft 11, and a connector 16 is provided on the other side of the bottom end of the swing arm 15. When the external driving motor fails, the connector 16 can be manually clamped and rotated. The connector 16 controls the rotation of the rotating shaft 11 through the swing arm 15, and the first chuck 1 and the second chuck 2 can be manually loosened.

[0032] Working principle: When in use, rotate the rotating shaft 11, and the rotating shaft 11 controls the swing block 12 to swing. When the swing block 12 swings, the transmission shaft 13 and the connecting rod 14 at both ends respectively drive the first chuck 1 and the second chuck 2 to swing synchronously. When the first chuck 1 and the second chuck 2 swing, the adjusting block 3 on the inner side thereof will move in the same direction to clamp the workpiece. When the rotating shaft 11 is reversed, the ends of the first chuck 1 and the second chuck 2 will be stretched outward, thereby loosening the clamped workpiece. When the workpiece to be clamped is longer, twist the adjusting knob 5, and the adjusting knob 5 controls the threaded rod 402 to rotate and exit along the inside of the thread groove 403. When the threaded rod 402 retreats, it controls the fixed block 401 to move synchronously, thereby making the adjusting block 3 on the inner side of the first chuck 1 and the second chuck 2 slide outward, so that it can be clamped in the middle position of the longer workpiece.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
