The left side of the No. 2 bevel gear is connected to the roller shaft. This device can only clamp and fix one end of the workpiece. When processing the workpiece, the structure with one end fixed is prone to movement and deformation of the workpiece in the later processing due to the action of the cutting tool. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, this utility model provides an adjustable steel structure processing fixture that uses a rotating connecting block, symmetrical strip connecting plates, and symmetrical rotating clamping plates to form a linkage structure. This allows the rotating connecting block to control the simultaneous rotation of the symmetrical strip connecting plates when rotating, and the symmetrical clamping plate protrusions to clamp and fix both ends of the steel part, ensuring the stability of the steel part processing.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] An adjustable steel structure processing fixture includes a mounting box, a vertical mounting plate, a positioning spindle, a second connecting lug, a rotating connecting block, a rotating clamping plate, a cylinder, and a strip connecting plate. The upper part of the mounting box has a clearance rectangular hole, and a set of clearance rectangular holes are distributed on the mounting box. The rotating clamping plate is adapted to the clearance rectangular hole and is inserted into the clearance rectangular hole, sliding within the clearance rectangular hole. The lower part of the clearance rectangular hole has a first connecting lug, the side of which fits against the rotating clamping plate. The first connecting lug is symmetrically arranged on both sides of the rotating clamping plate. The rotating clamping plate is connected to the symmetrical first connecting lugs through a fifth rotating shaft. A set of rotating clamping plates is symmetrically arranged on the mounting box. The upper part of the rotating clamping plate has a clamping plate protrusion, the side of which fits against the steel component.

[0006] The lower part of the rotating clamp has a clamp side groove, and the strip connecting plate is adapted to the clamp side groove. The strip connecting plate is inserted into the clamp side groove and is connected to the rotating clamp via the No. 4 rotating shaft. The side of the rotating connecting block has a side mounting groove, which is symmetrically arranged on both sides of the rotating connecting block. The strip connecting plate is adapted to the side mounting groove and is inserted into the side mounting groove. The strip connecting plate is connected to the rotating connecting block via the No. 3 rotating shaft. Beneficial effects

[0007] 1. In this utility model, the vertical mounting plate is installed and fixed inside the mounting box. The positioning spindle passes through the rotating connecting block and connects to the vertical mounting plate. The positioning spindle positions the rotating connecting block, fixing its center point and allowing it to rotate around the positioning spindle. The spindle side plate prevents the rotating connecting block from falling off the positioning spindle when the steel structure processing fixture is used. The rotating clamp is connected to the No. 1 connecting ear through the No. 5 rotating shaft, allowing the rotating clamp to be installed on the mounting box and rotate around the No. 5 rotating shaft. The length of the rectangular hole is greater than the width of the rotating clamp, allowing the rotating clamp to rotate and placing its upper part above the mounting box. The two ends of the strip connecting plate are connected to the rotating connecting block and the rotating clamp through the No. 3 and No. 4 rotating shafts, respectively. The rotating connecting block, the symmetrical strip connecting plate, and the symmetrical rotating clamp form a linkage structure, allowing the symmetrical strip connecting plate to rotate simultaneously when the rotating connecting block rotates.

[0008] 2. When the rotating connecting block rotates clockwise, the left side of the rotating connecting block drives the strip connecting plate upward, which in turn drives the left rotating clamping plate to rotate to the left. At this time, the rotating connecting block drives the right strip connecting plate downward, causing the strip connecting plate to drive the rotating clamping plate to rotate to the right. The rotation of the rotating connecting block drives the rotating clamping plate to rotate inward or outward simultaneously. When the symmetrical rotating clamping plate rotates inward, the symmetrical clamping plate protrusions clamp and fix the two ends of the steel part, ensuring the stability of the steel part processing. When the symmetrical rotating clamping plate rotates outward, the symmetrical clamping plate protrusions disconnect from the steel part, and the steel part can be removed. The two ends of the cylinder are connected to the first rotating shaft, the second rotating shaft, the first rotating shaft, and the third connecting trunnion, respectively. When the cylinder is working, it pushes and pulls the side connecting plate, causing the rotating connecting block to rotate, thereby controlling the movement of the symmetrical rotating clamping plate. When the device is in use, the push-pull length of the cylinder piston rod can be adjusted according to the length of the steel part. Attached Figure Description

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0015] Example 1:

[0016] An adjustable steel structure processing fixture includes a mounting box 01, a vertical mounting plate 04, a positioning spindle 05, a second connecting lug 07, a rotating connecting block 08, a rotating clamping plate 12, a cylinder 15, and a strip connecting plate 19. The mounting box 01 has a recessed rectangular hole 02 at its upper part, and a set of recessed rectangular holes 02 are distributed on the mounting box 01. The rotating clamping plate 12 is adapted to the recessed rectangular hole 02, inserts into the recessed rectangular hole 02, and slides within the recessed rectangular hole 02. A first connecting lug 03 is located at the lower part of the recessed rectangular hole 02, and the side of the first connecting lug 03 is connected to the rotating rectangular hole 07. The rotating clamp 12 is fitted together, and the first connecting ear 03 is symmetrically arranged on both sides of the rotating clamp 12. The rotating clamp 12 is connected to the symmetrical first connecting ear 03 through the fifth rotating shaft 22, so that the rotating clamp 12 is installed on the mounting box 01 and rotates with the fifth rotating shaft 22 as the axis. The length of the rectangular hole 02 is greater than the width of the rotating clamp 12, so that the rotation of the rotating clamp 12 is made room, and the upper part of the rotating clamp 12 is placed above the mounting box 01. A set of rotating clamps 12 is symmetrically arranged on the mounting box 01. The upper part of the rotating clamp 12 has a clamp protrusion 14, and the side of the clamp protrusion 14 is fitted with the steel component.

[0017] Example 2:

[0018] The rotating clamping plate 12 of this utility model has a clamping plate side groove 13 at its lower part. The strip connecting plate 19 is adapted to the clamping plate side groove 13 and is inserted into the clamping plate side groove 13. The strip connecting plate 19 is connected to the rotating clamping plate 12 through the fourth rotating shaft 21. The rotating connecting block 08 has a side mounting groove 09 on its side. The side mounting groove 09 is symmetrically arranged on both sides of the rotating connecting block 08. The strip connecting plate 19 is adapted to the side mounting groove 09 and is inserted into the side mounting groove 09. The strip connecting plate 19 is connected to the rotating connecting block 08 through the third rotating shaft 20. The two ends of the strip connecting plate 19 are connected to the rotating connecting block 08 and the rotating clamping plate 12 through the third rotating shaft 20 and the fourth rotating shaft 21, respectively. The rotating connecting block 08, the symmetrical strip connecting plate 19, and the symmetrical rotating clamping plate 12 form a linkage structure, so that when the rotating connecting block 08 rotates, it controls the symmetrical strip connecting plate 19 to rotate simultaneously.

[0019] Example 3:

[0020] The vertical mounting plate 04 of this utility model is connected to the mounting box 01 at its upper part. The vertical mounting plate 04 is installed and fixed inside the mounting box 01. The positioning spindle 05 is adapted to the rotating connecting block 08. The positioning spindle 05 passes through the rotating connecting block 08 and rotates inside the rotating connecting block 08. The positioning spindle 05 is connected to the vertical mounting plate 04. The positioning spindle 05 positions the rotating connecting block 08, so that the center point of the rotating connecting block 08 is fixed and the rotating connecting block 08 can rotate around the positioning spindle 05. The side of the positioning spindle 05 has a spindle side plate 06. The side of the spindle side plate 06 fits against the rotating connecting block 08. The spindle side plate 06 prevents the rotating connecting block 08 from falling off the positioning spindle 05 when the steel structure processing tooling fixture is used.

[0021] Example 4:

[0022] The rotating connecting block 08 of this utility model has a side connecting plate 10 on its side, and a third connecting ear 11 is connected to the side connecting plate 10. A second connecting ear 07 is connected inside the mounting box 01. One end of the cylinder 15 is connected to the second connecting ear 07 via a first rotating shaft 16, and the other end of the cylinder 15 is connected to the third connecting ear 11 via a second rotating shaft 18. When the rotating connecting block 08 rotates clockwise, the left side of the rotating connecting block 08 drives the strip connecting plate 19 upward, which in turn drives the left rotating clamping plate 12 to rotate to the left. At this time, the rotating connecting block 08 drives the right strip connecting plate 19 downward, causing the strip connecting plate 19 to drive the rotating clamping plate 12 to rotate to the right. The rotating connecting block 08 drives the rotating clamping plate 12 to rotate inward or outward simultaneously. When the symmetrical rotating clamping plate 12 rotates inward, the symmetrical clamping plate protrusion 14 clamps and fixes both ends of the steel part to ensure the stability of the steel part processing. When the symmetrical rotating clamping plate 12 rotates outward, the symmetrical clamping plate protrusion 14 disconnects from the steel part, and the steel part can be removed. The two ends of the cylinder 15 are respectively connected to the first rotating shaft 16 and the third connecting ear 11 through the first rotating shaft 16 and the second rotating shaft 18. When the cylinder 15 is working, it pushes and pulls the side connecting plate 10, causing the rotating connecting block 08 to rotate, thereby controlling the movement of the symmetrical rotating clamping plate 12.

[0023] Example 5:

[0024] The installation steps of this utility model are as follows: First, connect the positioning spindle 05 through the rotating connecting block 08 to the vertical mounting plate 04. Connect the upper part of the vertical mounting plate 04 to the mounting box 01. Pass the rotating clamp 12 through the clearance rectangular hole 02. Connect the rotating clamp 12 to the first connecting ear 03 through the fifth rotating shaft 22. Connect one end of the strip connecting plate 19 to the rotating clamp 12 through the fourth rotating shaft 21. Connect the other end of the strip connecting plate 19 to the rotating connecting block 08 through the third rotating shaft 20. Connect one end of the cylinder 15 to the third connecting ear 11 through the second rotating shaft 18. Connect the other end of the cylinder 15 to the second connecting ear 07 through the first rotating shaft 16.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
