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 scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Please see Figure 1-4 This utility model provides a technical solution: a clamping device for testing injection molded parts of vacuum cleaners, comprising:

[0033] The positioning base 1 has several protruding posts 2 at its corners. Adjacent protruding posts 2 form an outer groove 3 on the side of the positioning base 1, and several protruding posts 2 form an inner groove 4 in the center of the positioning base 1.

[0034] Side pressure block 5 is positioned on the movable seat 6. The telescopic drive device 7 drives the movable seat 6 to move and causes the side pressure block 5 to move toward the corresponding outer groove 3.

[0035] The upper pressure block 9 is connected to the swing arm 8, which is connected to the output shaft of the rotary drive device 10.

[0036] The telescopic drive device 7 is an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0037] The telescopic drive device 7 is positioned on the base plate 11, and a guide block 12 extends from the inner side of the base plate 11. The movable seat 6 slides against the guide block 12. This improves the stability of the moving trajectory of the movable seat 6.

[0038] The rotary drive device 10 is an ACK rotary cylinder.

[0039] A screw rod 13 is screwed to the end of the swing arm 8 away from the rotary drive device 10, and the screw rod 13 is inserted into the upper pressure block 9. A first nut 14 is screwed onto the screw rod 13, and the first nut 14 abuts against the end face of the swing arm 8. A second nut 15 is provided on the upper pressure block 9, and the second nut 15 is screwed to the screw rod 13. This realizes the detachable design of the swing arm 8 and the upper pressure block 9, so that the upper pressure block 9 can be selected and assembled according to different injection molded parts, and the height of the upper pressure block 9 is adjustable, thereby improving the clamping and positioning strength.

[0040] The working principle of a clamping device for testing injection molded vacuum cleaner parts in this embodiment includes: when clamping injection molded part 100, specifically as follows... Figure 2 As shown, injection molded part 100 is a rod-shaped or tubular structure. When the device is in use, injection molded part 100 is placed on the side of the positioning base 1 or in the outer groove 3 and inner groove 4. The moving seat 6 is driven to move, causing the side pressure block 5 to move towards the outer groove 3. This clamps the injection molded part 100 with the side pressure block 5 and the protruding post 2, or the two pressure blocks 5 on opposite sides. The clamping of the second injection molded part 110, which has a shell structure, is specifically as follows: Figure 3 As shown, the part is placed on the positioning base 1, and is laterally clamped by the side pressure block 5 and the protrusion 2. The rotary drive device 10 drives the swing arm 8 to rotate, so that the upper pressure block 9 presses on the top surface of the injection molded part 110, thereby vertically clamping and limiting the injection molded part 110 by the upper pressure block 9 and the protrusion 2. This clamping device can be used for clamping and positioning of vacuum cleaner injection molded parts of various shapes during testing.

[0041] In summary, due to the adoption of the above technical solution, the clamping device for testing vacuum cleaner injection molded parts in this embodiment has the following advantages compared with the prior art:

[0042] The clamping device of this utility model can be used for clamping and positioning during testing of vacuum cleaner injection molded parts of various shapes; the swing arm and the upper pressure block adopt a detachable design, so that the upper pressure block can be selected and assembled according to different injection molded parts, and the height of the upper pressure block is adjustable, thereby improving the clamping and positioning strength.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
