Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0019] Example 1: See Figures 1 to 2This is a structural view and an assembly view in use of the present invention. It describes an adjustable repositioning clamping device, comprising a base plate 1, a base 2 connected to the upper end of the base plate 1, a socket 3 on the upper surface of the base 2, and the base plate 1 and base 2 for connection to a workbench. A mounting post 13 is provided on the side of the socket 3, the mounting post 13 including a base, a lead screw connected to the upper end of the base, a spring 12 on the outer side of the lead screw, a second sleeve 7 slidably mounted on the upper end of the spring 12 and the outer side of the lead screw, and an adjusting nut 6 threadedly connected to the upper end of the second sleeve 7 and the outer side of the lead screw. A washer is provided between the adjusting nut 6 and the end of the second sleeve 7. By operating the adjusting nut 6, it can be pressed down or raised along the axis of the lead screw, thereby squeezing the washer and the second sleeve 7, allowing the second sleeve 7 to squeeze the spring 12 to achieve height adjustment.

[0020] The second sleeve 7 is connected to the first sleeve 5 and the third sleeve 8 on both sides by connecting ribs 11. A movable pin 4 is fixedly installed inside the first sleeve 5. The lower end of the movable pin 4 is located inside the socket 3. The movable pin 4 and the socket 3 are slidably engaged. A first positioning pin 9 is installed inside the third sleeve 8. A set screw 10 is threadedly connected to the inner side wall of the third sleeve 8. The first positioning pin 9 is fixed inside the third sleeve 8 by the set screw 10. The end of the set screw 10 is tightened and locked with the first positioning pin 9 to prevent the first positioning pin 9 from sliding. The movable pin 4 slides up and down inside the socket 3 along the axis of the socket 3, which can ensure that the third sleeve 8 connected to the first sleeve 5 by the connecting ribs 11 and the first positioning pin 9 installed inside the third sleeve 8 can move in a straight line to ensure verticality.

[0021] The mounting column 13 and the socket 3 are connected by a connecting stiffener 11.

[0022] A first positioning slot 14 is provided on the side of the mounting post 13, and a second positioning slot 16 is provided on the side of the first positioning slot 14. A second positioning pin 15 is provided inside the first positioning slot 14. The axes of the first positioning pin 9 and the second positioning pin 15 coincide. The first positioning pin 9 and the second positioning pin 15 have the same structure. The first positioning pin 9 includes a mounting rod, and a pin head is fixedly provided at the end of the mounting rod. The first positioning slot 14 and the second positioning slot 16 have the same structure. Insertion holes are provided at the mounting locations of the first positioning slot 14 and the second positioning slot 16 on the base 2. The diameter of the insertion holes is smaller than that of the first positioning slot 14. The inner diameter of the insertion hole is matched with the mounting rod. The insertion position of the second positioning pin 15 can be changed by manually inserting and removing the second positioning pin 15. At the same time, the positioning holes on the counterweights of different specifications can be matched by changing the specifications and dimensions of the second positioning pin 15 and the first positioning pin 9. When the axes of the first positioning pin 9 and the second positioning pin 15 are aligned and positioned, the cover plate hole and the bottom plate 1 hole of the counterweight are positioned at the same time. The first positioning pin 9 is pressed against the counterweight by operating the adjusting bolt. When the second positioning pin 15 is inserted into the insertion hole, it will not fall downward because the outer diameter of the pin head is larger than the diameter of the insertion hole.

[0023] This utility model is used in conjunction with the auxiliary device of the excavator main frame assembly for quick positioning of the counterweight. Through the second positioning pin 15, which can be adjusted in position, it can be applied to the positioning of counterweights of various specifications.

[0024] This utility model uses multiple positioning slots in conjunction with interchangeable positioning pins to achieve the purpose of matching various specifications of counterweights. It achieves the functions of simple structure, low cost, adjustable positioning position, wide applicability, and improved assembly efficiency.
