[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0020] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0021] like Figures 1 to 4 As shown, a composite zero-point positioning base includes a base body 10, on which a first positioning hole 11 and a second positioning hole 12 are provided. The fixing rivets in the first positioning hole 11 and the second positioning hole 12 are spaced at different distances. By providing the first positioning hole 11 and the second positioning hole 12 on the base body 10, different specifications of fixtures can be connected on the same base through either the first positioning hole 11 or the second positioning hole 12, thereby avoiding frequent base replacements and improving processing efficiency. In practical applications, the distance between the first positioning holes 11 is smaller than the distance between the second positioning holes 12. Therefore, the first positioning hole 11 is usually used to connect to a fixture with a specification of 52mm, and the second positioning hole 12 is used to connect to a fixture with a specification of 96mm.

[0022] The base body 10 is provided with a locking stud 13, a transmission stud 14, and a set pin. The locking stud 13 has a driving end and a transmission end, the transmission end being connected to the transmission stud 14, and the transmission stud 14 being connected to the set pin. In this embodiment, by rotating the locking stud 13, the transmission stud 14 can be driven to push the set pin, thereby locking the first positioning hole 11 or the second positioning hole 12, and thus achieving a stable connection between the clamp and the base body 10.

[0023] The locking pins include a first locating pin group 15 for locking with the first locating hole 11 and a second locating pin group 16 for locking with the second locating hole 12. The drive stud 14 includes a first connecting portion and a second connecting portion. The first connecting portion is drively connected to the first locating pin group 15, and the second connecting portion is drively connected to the second locating pin group 16. In this embodiment, the first locating pin group 15 and the second locating pin group 16 lock the first locating hole 11 and the second locating hole 12 respectively, thereby facilitating the connection between the clamp and the base body 10. At the same time, the drive stud 14 is drively connected to the first locating pin group 15 and the second locating pin group 16 respectively, thereby facilitating the simultaneous driving of the first locating pin group 15 and the second locating pin group 16.

[0024] The transmission end is conical, and the end of the transmission stud 14 that contacts the locking stud 13 has a chamfered edge corresponding to the transmission end. In this embodiment, the transmission end of the locking stud 13 is conical to facilitate connection with the transmission stud 14. When the locking stud 13 is rotated to lock, the transmission end transmits power to the transmission stud 14 at a uniform speed to lock the first positioning hole 11 and the second positioning hole 12. When the locking stud 13 is rotated to unlock, the transmission stud 14 will return to its original position at a uniform speed due to loss of power, thereby improving locking and unlocking stability.

[0025] One end of the locking stud 13 is flush with the edge of the base body 10, and the end of the locking stud 13 is provided with an inwardly recessed connecting hole to form a driving end. In this embodiment, by providing an inwardly recessed connecting hole at the driving end of the locking stud 13, an external driving component can drive the locking stud 13 through the connecting hole.

[0026] A tapered connecting groove is provided at the first connecting part, and the first positioning pin group 15 is located in the tapered connecting groove. One end of the first positioning pin group 15 located in the tapered connecting groove is conical. In this embodiment, a tapered connecting groove is provided at the first connecting part. When the transmission stud 14 is locked, the tapered connecting groove compresses the first positioning pin group 15 to achieve the locking movement of the first positioning pin group 15. When the transmission stud 14 is unlocked, the tapered connecting groove resets and compresses the first positioning pin group 15 to achieve the unlocking movement of the first positioning pin group 15.

[0027] The end of the drive stud 14 that contacts the second positioning pin group 16 is conical, and the end of the second positioning pin group 16 that contacts the drive stud 14 has a corresponding chamfered edge. In this embodiment, the end of the drive stud 14 that contacts the second positioning pin group 16 is conical to facilitate connection with the second positioning pin group 16. When the drive stud 14 is locked, it transmits power to the second positioning pin group 16 at a uniform speed. When the drive stud 14 is unlocked, the second positioning pin group 16 resets at a uniform speed, thereby improving locking and unlocking stability.

[0028] The second positioning pin assembly 16 includes two separately arranged locking bodies, with a return spring 17 connected to each of the two locking bodies. In this embodiment, the locking bodies are unlocked and reset by using the return spring 17.

[0029] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
