Detailed implementation mode

[0023] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Embodiment 1: An adjustable lateral clamping device. Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 shown in the figures. It includes: a base 1, a workpiece 2, an outer cover 3, a cover plate 4, a spring 5, a fixing screw 6 and a fixture positioning pin 7. A workpiece 2 is placed on the base 1. An outer cover 3 is slidably arranged on the base 1. A spring 5 is placed inside the outer cover 3. A fixture positioning pin 7 is connected to the spring 5. The head part of the fixture positioning pin 7 is in a conical shape, which can reduce resistance and facilitate the workpiece to be clamped in. The spring 5 is located below the boss of the fixture positioning pin 7. A cover plate 4 is slidably arranged on the outer cover 3. The cover plate 4 is located above the boss of the fixture positioning pin 7. Three fixing screws 6 are threadedly arranged on the cover plate 4. When the fixture positioning pin 7 needs to be replaced, turn the fixing screws 6 and then pull up the cover plate 4 to open the outer cover 3. The top of the fixture positioning pin 7 is fixedly connected to a pull rod 13. A conical surface is arranged outside the fixture positioning pin 7. When placing the workpiece 2, press the workpiece 2 downward so that one side of the workpiece 2 abuts against the conical surface of the fixture positioning pin 7 to fix the workpiece 2. When the workpiece 2 needs to be taken out, pull the pull rod 13 to the right to make the fixture positioning pin 7 tilt to the right, so as to facilitate the taking out of the workpiece 2. A second limiting frame 14 is arranged on the cover plate 4 by bolt connection to limit the pull rod 13. A baffle plate 15 is arranged on the top of the base 1 by bolt connection to limit the workpiece 2, thereby preventing the workpiece 2 from slipping off the base 1.

[0025] When the device is needed, one end of the workpiece 2 is placed on the base 1, so that the fixture positioning pin 7 is squeezed and tilted to the lower right direction by the force from the lower right, and the spring 5 is deformed accordingly. After the workpiece 2 is placed on the base 1, the spring 5 returns to its original shape and generates a rebound force to tilt the fixture positioning pin 7 to the upper left direction and reset, thereby clamping the workpiece 2. By designing the fixture positioning pin 7 into a cone-shaped shape, the resistance to the insertion of the workpiece 2 is reduced, making the workpiece 2 smoother to be inserted, thereby avoiding the situation of getting stuck, and thus extending the service life of the fixture positioning pin 7. After the workpiece 2 is fixed, the workpiece 2 is processed using tools.

[0026] Example 2: Based on Example 1, please refer to Figure 3 The bottom of the outer cover 3 is fixedly connected with a bolt 8, and a nut 9 is threadedly arranged on the bolt 8.

[0027] When it is necessary to process workpieces 2 of different lengths, turn the nut 9 to disengage it from the bolt 8, and then move the outer cover 3, so that the outer cover 3 moves to drive the fixture positioning pin 7 to move, and then adjust the distance between the fixture positioning pin 7 and the top of the base 1, so as to adjust the position of the fixture positioning pin 7 according to the use requirements, so as to facilitate use and improve the applicability of the device. After adjusting the fixture positioning pin 7 to a suitable position, reverse the nut 9 to make it contact with the base 1, and then fix the outer cover 3 on the base 1.

[0028] Please refer to Figure 1 、 Figure 4 and Figure 5 , a sliding frame 10 is provided on the base 1 by bolt connection, a first limiting frame 11 is slidably provided on the sliding frame 10, the contact surface between the first limiting frame 11 and the outer cover 3 is a curved surface, thereby increasing the contact nep with the outer cover 3, a screw rod 12 is rotatably provided on the front side of the sliding frame 10, and the sliding frame 10 is threadedly connected to the screw rod 12.

[0029] When the outer cover 3 needs to be moved, the screw 12 is first rotated to make the first limit frame 11 move and disengage from the outer cover 3, and then the outer cover 3 is moved to a suitable position, and then the screw 12 is reversed to make the first limit frame 11 move and contact the outer cover 3, thereby limiting the outer cover 3, thereby preventing the nut 9 from loosening and causing the outer cover 3 to move when the workpiece 2 is placed.

[0030] Although the embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.​​
