[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Please see attached Figure 1 - Attachment Figure 2, the utility model provides an embodiment: a pulley processing internal expansion positioning device, including an L-shaped frame 1, a square frame 8 is arranged on the left and right sides of the top of the L-shaped frame 1, a circular column 5 is fixedly connected to the middle of the front side of the square frame 8, and a telescopic rod 12 is fixedly connected to the outer wall of the circular column 5. The output end of the telescopic rod 12 is fixedly connected to a C-shaped expansion strip 7, and the outward side of the C-shaped expansion strip 7 is fixedly connected to an anti-slip strip 9, and holes 10 are arranged between adjacent C-shaped expansion strips 7. Long blocks 11 are slidably connected between adjacent holes 10. A lifting mechanism 2 is arranged in the middle of the top of the L-shaped frame 1, and a lighting lamp 6 is fixedly connected to the top of the inner rear side of the L-shaped frame 1;

[0030] Specifically, the telescopic rod 12 is a member with adjustable length, which can be extended or shortened when subjected to force, so as to adapt to different usage requirements. The output ends of these telescopic rods 12 are fixedly connected with C-shaped expansion strips 7, and the design of the C-shaped expansion strips 7 enables them to expand or contract within a certain range. The outward side of the C-shaped expansion strips 7 is fixedly connected with anti-slip strips 9. The presence of the anti-slip strips 9 can effectively provide friction, prevent objects from sliding, and ensure the stability and safety of the structure. The elongated block 11 can slide inside the hole 10. Such a design allows the C-shaped expansion strips 7 to maintain appropriate spacing during the telescopic process, and also provides additional flexibility and adjustment capabilities for the entire structure.

[0031] Please see attached Figure 3 The lifting mechanism 2 includes a double-headed motor 201, the output end of the double-headed motor 201 is fixedly connected to a threaded rod 210, the outer wall of the threaded rod 210 is threadedly connected to a slider 209, the top of the slider 209 is fixedly connected to a second shaft 208, the top of the outer wall of the second shaft 208 is rotatably connected to an inclined plate 206, the other end of the inclined plate 206 is rotatably connected to a first shaft 202, the top of the first shaft 202 is fixedly connected to a support plate 203 between adjacent top ends, the left and right sides of the support plate 203 are fixedly connected to support columns 13, the rear side of the support column 13 is fixedly connected to a T-shaped block 204, a T-shaped slot 205 is provided on the front side of the L-shaped frame 1, and the inside of the T-shaped slot 205 is slidably connected to the outer wall of the T-shaped block 204;

[0032] Specifically, the double-headed motor 201 is fixedly connected to a threaded rod 210 through its output end. The design of the threaded rod 210 is very clever, because its outer wall is evenly provided with threads, so that the slider 209 can move along the axis direction of the threaded rod 210. The slider 209 plays a vital role in this mechanism, because they are not only the moving carrier, but also their top ends are fixedly connected to the second rotating shaft 208. The design of the inclined plate 206 makes it connected to the second rotating shaft 208 at one end, and the other end is rotatably connected to the first rotating shaft 202, and finally cooperates to move the support plate 203 upward.

[0033] Please see attached Figure 1 and attached Figure 3 The front and rear sides of the bottom of the L-shaped frame 1 are fixedly connected with a support block 3, the inner bottom of the L-shaped frame 1 is fixedly connected with an anti-slip pad 4, the front side of the support column 13 is fixedly connected to the middle of the rear side of the square frame 8, and the top left side of the L-shaped frame 1 is fixedly connected with a controller 207, and the controller 207 is electrically connected to the double-headed motor 201, the lighting lamp 6 and the telescopic rod 12 respectively, and the two square frames 8 are set at the same horizontal height;

[0034] Specifically, the design of the L-shaped frame 1 takes stability and functionality into consideration. In order to enhance its stability, support blocks 3 are provided on both the front and rear sides of the bottom end of the L-shaped frame 1. These support blocks 3 provide additional support for the L-shaped frame 1 by means of fixed connection. An anti-skid pad 4 is fixedly connected to the inner bottom end of the L-shaped frame 1. The function of the anti-skid pad 4 is to increase friction with the ground, thereby further ensuring the stability of the L-shaped frame 1 during use. A controller 207 is fixedly connected to the left side of the top of the L-shaped frame 1. The presence of the controller 207 indicates that the L-shaped frame 1 may be used to support something that needs to be controlled.

[0035] Working principle: when the pulley needs to be positioned internally, first pick up the pulley, fit it with the outer wall of the C-shaped expansion strip 7, fit it with the inner side of the pulley through the outer wall of the anti-slip strip 9, and start the effective protection function. At this time, the middle part of the square frame 8 is fixedly connected with a circular column 5, and then the telescopic rod 12 fixedly connected to the circular column 5 is started, and the C-shaped expansion strip 7 is pushed outward, so that the hole 10 slowly slides out from the inner side of the elongated block 11, so that the C-shaped expansion strip 7 can be expanded and adjusted to fit tightly with the inner side of the pulley. Therefore, it can be adjusted according to different types of pulleys. The double-headed motor 201 is started to rotate the threaded rod 210, thereby cooperating with the slider 209 threadedly connected on the outer wall and the second shaft 208 to move relative to each other, and the other end of the inclined plate 206 cooperates with the shaft 1 202 to move the support plate 203 upward, and at the same time cooperates with the T-block 204 to slide and rise along the inner side of the T-slot 205. Therefore, the height of the pulley can be adjusted according to the height of the operator, which is convenient for the subsequent operator to process the pulley and improves the work efficiency to a certain extent.

[0036] Finally, it should be noted that the above is only 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 can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
