DETAILED DESCRIPTION

[0021] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0022] Example: See Figure 1-4 The utility model provides a technical solution: a universal fixture. This solution takes into account that the existing fixture can only clamp and fix materials of a single shape, has great limitations in use, and cannot achieve stable clamping when fixing materials of different types. Based on the above content, this case discloses the following technical means:

[0023] Specifically, the device at least includes an equipment base 1, a mounting slot 2, an opposing linear slide 3, a pair of moving blocks 4, a plurality of sliding rails 5, a pair of moving plates 6, two pairs of rotating clamping assemblies, a pair of telescopic push rods 7 and a support roller frame 8;

[0024] The rotary clamping assembly includes: a mounting seat 11, an embedding groove 12, a rotating seat 13, a support rod 14, a first clamping bracket 15, a second clamping bracket 16, a fixing block 17, an adjusting groove 18, a compression spring 19, an adjusting block 20, an adjusting rod 21 and an insert fixing rod 22;

[0025] The equipment base 1 supports the whole equipment, and the opposite linear slide 3 arranged in the installation groove 2 cooperates with the moving block 4 to form a clamping drive structure, which drives the moving plate 6 to move toward the middle on the sliding track 5 and drives the upper rotating clamping assembly to move to clamp and fix the processed material. When the material is long, the extension length of the telescopic push rod 7 is adjusted to drive the support roller frame 8 to move up and down to support the longer extended part of the material, thereby ensuring the stability of the clamping;

[0026] When clamping the material, the mounting seat 11 supports the clamping structure installed thereon, and the movable plate 6 drives the support rod 14 to move toward the middle to cooperate with the first clamping bracket 15 to clamp and fix the square material through the clamping friction force, and cooperates with the anti-slip rubber sheet 23 to increase the friction performance to ensure stable clamping. When it is necessary to clamp and fix the columnar material, the adjusting rod 21 is pulled outward, and the adjusting rod 21 drives the adjusting block 20 installed in the adjusting groove 18 opened inside the fixing block 17 to move outward, and at the same time drives the fixed rod 22 installed on the other side of the adjusting block 20 to be pulled out from the rotating seat 13 and contracted to the adjusting groove 18 to release the locking of the rotating seat 13. When the adjusting block 20 moves outward, it compresses the compression spring 19, rotates the rotating seat 13 installed in the embedding groove 12 to change its direction and drives the upper support rod 14 to rotate for angle adjustment, thereby driving the second clamping bracket 16 installed on the support rod 14 to rotate to the inside. After the rotation is completed, the adjusting rod 21 is released, and the adjusting block 20 rebounds under the drive of the rebound force of the compression spring 19 and drives the insertion fixing rod 22 to be inserted into the insertion hole 24 provided on the rotating seat 13, and the rotating seat 13 is locked and fixed again, thereby realizing the adjustment of the clamping bracket, and the columnar material is clamped and fixed by the second clamping bracket 16 to realize universal clamping.

[0027] In the specific implementation process, further, the internal structure of the opposing linear slide 3 used in this scheme is provided with positive and negative threaded screws, and the positive and negative threaded screws are driven by a rotating motor to rotate through the opposite threaded grooves to drive the moving block 4 to move in opposite directions.

[0028] In the specific implementation process, further, the moving block 4 is installed on a pair of moving plates 6 through fixing bolts 9, which are used to stably connect the moving block 4 with the moving plates 6 and cooperate with the opposite linear slide 3 to drive the moving plates 6 to move.

[0029] In the specific implementation process, further, a support frame 10 is installed on the pair of telescopic push rods 7 to support the telescopic push rods 7 to ensure the stability of the equipment when it is used, thereby ensuring the support stability of the long workpiece.

[0030] In the specific implementation process, further, an anti-skid rubber sheet 23 is installed on the first clamping bracket 15 to increase the friction between the first clamping bracket 15 and the square workpiece to prevent the workpiece from shifting due to force.

[0031] In the specific implementation process, further, a pair of insertion holes 24 are opened on the rotating seat 13 for inserting and locking the fixing rod 22 , and the rotating seat 13 is rotationally limited by inserting the fixing rod 22 .

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
