Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figure 1 As shown;

[0027] A detection fixed seat capable of rapid clamping and limiting, comprising a fixed shell 1 and a base plate 11 disposed below the fixed shell 1. The base plate 11 is rotatably connected to the fixed shell 1 via a first bearing seat 12. An electric push rod 13 is fixedly connected to the surface of the fixed shell 1 via a mounting seat. The output shaft of the electric push rod 13 is rotatably connected to the fixed shell 1 via a bearing seat.

[0028] In this embodiment: After investigation, the public (announcement) number: CN214559076U discloses a mechanical processing clamping device. In order to solve the technical problems existing in this prior art, such as the above background technology disclosure that "when the detection fixing seat is clamped, both hands are required to apply force for clamping, which is inconvenient when operated by one person", this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a clamping component 2 and a buffer component 3 are added on this basis.

[0029] More specifically:

[0030] like Figures 1 to 4 As shown;

[0031] Combining the above:

[0032] In order to facilitate single-handed clamping of mechanical parts, this fast clamping and limiting detection fixing seat also includes a clamping component 2 arranged inside the fixing shell 1;

[0033] The clamping assembly 2 includes two positioning holes symmetrically opened inside the fixed shell 1, and a positioning cylinder 21 is provided inside the two positioning holes. The positioning cylinder 21 is slidingly connected to the fixed shell 1 through the positioning hole. A positioning rod 22 is provided at the adjacent end of the two positioning cylinders 21, and the positioning rod 22 is slidingly connected to the positioning cylinder 21. A positioning plate 25 is fixedly connected to the surface of each positioning cylinder 21, and a bidirectional screw 23 is provided inside the fixed shell 1. The bidirectional screw 23 is rotatably connected to the fixed shell 1 through a bearing. One end of the bidirectional screw 23 passes through the fixed shell 1 and is fixedly connected to a handwheel 24 provided on the outside of the fixed shell 1. The two positioning plates 25 are both threadedly connected to the bidirectional screw 23.

[0034] In this embodiment: when it is necessary to clamp the mechanical parts, force is applied to the hand wheel 24, the bidirectional screw 23 will rotate inside the fixed shell 1, the two positioning plates 25 will move toward the center, and the two positioning cylinders 21 will slide inside the positioning holes, so that the two positioning rods 22 will squeeze the mechanical parts, thereby achieving single-handed clamping of the mechanical parts.

[0035] Going further:

[0036] In an optional embodiment, a sliding groove is opened inside the fixed shell 1, and the end of the positioning plate 25 away from the positioning cylinder 21 is inserted into the sliding groove. The positioning plate 25 is slidably connected to the fixed shell 1 through the sliding groove.

[0037] In this embodiment, when clamping the mechanical parts, the positioning plate 25 will slide inside the slide groove, and the slide groove will limit the positioning plate 25 to prevent dislocation.

[0038] Going further:

[0039] In an optional embodiment, a latex pad 26 is provided at one end of the positioning rod 22 away from the positioning cylinder 21 , and a corrugated groove is provided on adjacent sides of the two latex pads 26 .

[0040] In this embodiment, when the mechanical parts are clamped, the two latex pads 26 will fit the mechanical parts, and the wave grooves provided on the latex pads 26 will increase the friction on the mechanical parts to prevent them from slipping.

[0041] It should be noted that the material of the latex pad 26 can protect the mechanical parts and prevent them from being damaged.

[0042] Going further:

[0043] In an optional embodiment, a damping bearing 27 is installed on the surface of the positioning rod 22 , and the side of the damping bearing 27 away from the positioning rod 22 is fixedly connected to the latex pad 26 .

[0044] In this embodiment, after the mechanical part is clamped, the mechanical part can be rotated by the damping bearing 27, so that the mechanical part can be detected from all directions.

[0045] Going further:

[0046] In an optional embodiment, the buffer assembly 3 is further included and disposed inside the positioning cylinder 21;

[0047] The buffer assembly 3 includes a spring 31 disposed inside the positioning cylinder 21 , and two ends of the spring 31 are fixedly connected to the positioning rod 22 and the positioning cylinder 21 respectively.

[0048] In this embodiment: when clamping the mechanical parts, the two latex pads 26 clamp the mechanical parts, and the positioning rod 22 will be forced to slide inside the positioning cylinder 21 to prevent the operator from applying too much force, which will cause the mechanical parts to be squeezed and deformed.

[0049] When the mechanical part needs to be clamped, the hand wheel 24 is forced to apply force, the two-way screw 23 is rotated inside the fixed shell 1, and the two positioning plates 25 are close to the center. The two positioning cylinders 21 slide inside the positioning holes, so that the two positioning rods 22 squeeze the mechanical part, realizing one-handed clamping of the mechanical part. When the mechanical part is clamped, the positioning plates 25 slide inside the slide groove, and the slide groove limits the positioning plates 25 to prevent misalignment. When the mechanical part is clamped, the two latex pads 26 fit with the mechanical part, and the wave grooves provided by the latex pads 26 increase the friction of the mechanical part and prevent it from slipping. After the mechanical part is clamped, the mechanical part can be rotated by the damping bearing 27, and the mechanical part can be detected in all directions. When the mechanical part is clamped, the two latex pads 26 clamp the mechanical part, and the positioning rod 22 is forced to slide inside the positioning cylinder 21 to prevent the operator from applying too much force, which will cause the mechanical part to be squeezed and deformed.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
