[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 The present invention provides a technical solution as follows:

[0022] Example 1:

[0023] A nut clamping fixture with an adjustable function includes a base 1, a pull rod 2 fixedly connected to the top of the base 1, a pressure spring 3 installed through the outside of the pull rod 2, a top plate 4 fixedly connected to one end of the pressure spring 3, a sleeve 5 fixedly connected to the bottom of the top plate 4, a lifting spring 6 fixedly connected to the top of the base 1, a connecting plate 7 fixedly connected to one end of the lifting spring 6, an inner rod 8 fixedly connected to the bottom of the connecting plate 7, a spring support 9 fixedly connected to one end of the inner rod 8, and a positioning component 10 engaged with the bottom of the top plate 4.

[0024] The above structure utilizes the design of the pressure spring 3 to facilitate the quick release of the clamped nut, and the elastic support 9 structure designed for the clamping position of the nut clamping fixture enables the nut clamping device to have an adjustment function.

[0025] Furthermore, the pull rod 2 passes through the top plate 4 and the pressure spring 3 and is fixedly connected to the top of the base 1. The pull rod 2 is located at the midpoint of the base 1. The top plate 4 and the base 1 are parallel to each other. The sleeve 5 passes through the base 1 and is provided with four sets.

[0026] The above structure uses the elastic force of the pressure spring 3 to cause the base 1 to spring back, which facilitates the clamping and installation of the nut.

[0027] Furthermore, the inner rod 8 passes through the lifting spring 6 and the sleeve 5 and is fixedly connected to the bottom of the connecting plate 7. One end of the inner rod 8 is fixedly connected to the outer wall of the sleeve 5 through the elastic support 9. The bottom of the base 1 is provided with a limiting cylinder 11, and the number of limiting cylinders 11 corresponds to the number of sleeves 5.

[0028] Furthermore, the positioning component 10 includes a tray 1001, a ball bearing 1002, a first positioning cylinder 1003, and a second positioning cylinder 1004. The bottom of the top plate 4 is engaged with the tray 1001. The ball bearing 1002 is rolled inside the tray 1001. The first positioning cylinder 1003 is fixedly connected inside the tray 1001. The second positioning cylinder 1004 is slidably installed inside the first positioning cylinder 1003. The position of the first positioning cylinder 1003 corresponds to the position of the elastic support 9, and the size of the second positioning cylinder 1004 is smaller than that of the first positioning cylinder 1003.

[0029] The above structure matches the size of the positioning component 10 with the size of the base 1 above. The positioning component 10 can be used to quickly position the nut and quickly install the nut on the outside of the elastic support 9.

[0030] Working principle: When in use, first, put the nut into the positioning component 10 and shake the tray 1001 to make the nut roll inside the tray 1001. Affected by the slot on the tray 1001, the nut falls into the first positioning cylinder 1003. When the nut is small, the second positioning cylinder 1004 unfolds under the influence of the gravity of the nut above, and plays a supporting role at the bottom.

[0031] Secondly, the size of the positioning component 10 matches the size of the base 1 above. The positioning component 10 can be used to quickly position the nut and quickly install the nut on the outside of the elastic support 9. The first positioning cylinder 1003 and the second positioning cylinder 1004 are used to ensure that the nut occupies a completely fixed and unique position in the jig, achieving complete positioning. The first positioning cylinder 1003 and the second positioning cylinder 1004 can be adjusted to accommodate nuts of different sizes. The upper inner rod 8 passes through, allowing the nut to be quickly installed, accurately placed and clamped, facilitating the subsequent processing of the nut and improving the placement speed of the nut.

[0032] Finally, by adjusting the distance between the connecting plate 7 and the base 1, the adjustment and disengagement operations are achieved. The elastic support 9 structure designed for the clamping position of this nut clamping fixture enables the nut clamping device to have an adjustment function. The tension between the inner rod 8 and the sleeve 5 allows the elastic support 9 to be straightened or compressed. The elastic support 9 in the fixture can be adjusted to accommodate nuts of different sizes. Using the lifting spring 6 at the top, the fixture can adapt to the clamping operation of nuts of different sizes through a simple telescopic adjustment function, increasing the fixture's versatility and flexibility. Furthermore, when the nut size is large, the center hole diameter is also large; the elastic support 9 can support the inner wall of the nut, thereby limiting its movement. This allows it to accommodate nuts of various sizes, reducing the need for special fixtures and thus lowering production costs.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
