[0020] The following will refer to the appendix in the embodiments of this utility model. Figs. 1-2 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example:

[0022] like Figs. 1-2 As shown, this utility model discloses a clamping device for processing aluminum rods, including a base 1. Two clamping blocks 2 are symmetrically arranged on the left and right sides of the base 1. At the same time, the base 1 is provided with an elastic pressing mechanism for bringing the two clamping blocks 2 closer to each other and a distancing mechanism for extending the distance between the two clamping blocks 2. The elastic pressing mechanism and the distancing mechanism are respectively used to clamp the clamping blocks 2 and release the aluminum rod.

[0023] A ramp 21 is formed between the upper end face of clamping block 2 and the end face of clamping block 2 facing another clamping block 2. A telescopic rod 3 is provided on the ramp 21. One end of the telescopic rod 3 is fixedly connected to the clamping block 2 and the other end extends towards the other clamping block 2. The telescopic direction of the telescopic rod 3 is consistent with the inclination direction of the ramp 21. In addition, a clamping bead 33 is fixedly provided on the end of the telescopic rod 3 facing the other clamping block 2. Furthermore, an elastic extension mechanism is provided on the telescopic rod 3. In this structure, the elastic extension mechanism is used to press the clamping bead 33 into the middle of the aluminum rod at an upward position so that the clamping bead 33 can prevent the aluminum rod from tilting upward.

[0024] Furthermore, the telescopic rod 3 includes a fixed rod 31 and a movable rod 32. The fixed rod 31 is fixedly mounted on the clamping block 2. One end of the movable rod 32 is slidably connected to the fixed rod 31 and the other end is fixedly connected to the clamping bead 33. Meanwhile, the elastic extension mechanism includes a first elastic abutment member 34 that abuts against the clamping bead 33 and the fixed rod 31.

[0025] Furthermore, each clamping block 2 is equipped with a stop plate 41 and a guide post 42. In this structure, the stop plate 41 and the guide post 42 are both located on the side of the clamping block 2 facing away from the other clamping block 2. The stop plate 41 is fixedly mounted on the mounting base, and the guide post 42 is fixedly mounted on the clamping block 2. The guide post 42 is slidably mounted on the stop plate 41 to limit the sliding path of the clamping block 2. Meanwhile, the elastic compression mechanism includes a second elastic abutment member 43 that abuts against the clamping block 2 and the stop plate 41.

[0026] Furthermore, the disengagement mechanism is provided in two sets, and each set of disengagement mechanisms is respectively matched with a clamping block 2. The disengagement mechanism specifically includes a cylinder 52 and a push plate 51. The cylinder 52 and the push plate 51 are respectively arranged on the left and right sides of the clamping block 2. Preferably, the push plate 51 is arranged on the side of the clamping block 2 facing away from the guide post 42. At the same time, the cylinder 52 is fixedly installed on the base 1 and its piston rod is fixedly connected to the push plate 51.

[0027] A limiting groove 11 is provided on the base 1, and the limiting groove 11 is located between the two clamping blocks 2.

[0028] The working principle of the above structure is as follows: First, the cylinder 52 drives the push plate 51 to move and push the two clamping blocks 2 away from each other. When the distance between the two clamping blocks 2 is greater than the diameter of the aluminum rod, the aluminum rod is placed on the base 1. At this time, the aluminum rod can be pushed so that the lower end of the aluminum rod is just inserted into the limiting groove 11. At this time, the aluminum rod can remain stationary on the base 1. Then, the cylinder 52 drives the push plate 51 to move closer to each other. At this time, the second elastic abutment 43 can push the two clamping blocks 2 to move closer to each other until the two clamping blocks 2 abut against the left and right sides of the aluminum rod. During the process of the two clamping blocks 2 moving closer to the aluminum rod, the clamping bead 33 will also gradually move closer to the aluminum rod under the action of the first elastic abutment 34 until it is pressed against the surface of the aluminum rod.

[0029] The clamping bead 33 is wrapped with a layer of rubber pad 35.

[0030] A layer of rubber surface 22 is provided on each of the opposite end faces of the push plate 51.

[0031] Both the first elastic support member 34 and the second elastic support member 43 can be springs.

[0032] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
