For some medium to heavy-duty workpieces, some existing laser cutting equipment is equipped with a rear clamping feeding assembly. This assembly clamps the rear end of the workpiece and pushes it forward. The workpiece does not need to rotate; the laser cutting head rotates to cut the workpiece. However, these rear clamping feeding assemblies have relatively complex structures. Utility Model Content
[0003] The main purpose of this utility model is to propose a feeding support clamp assembly, which aims to solve the technical problem of the complex structure of the rear clamp feeding assembly in the prior art.

The first vertical plate is spaced apart on the front side of the front vertical plate. The rear side of the first upper horizontal plate is slidably connected to the upper side of the front vertical plate. The rear side of the first lower horizontal plate is slidably connected to the lower side of the front vertical plate. The first gripper arm is located on the front side of the first vertical plate. The second gripper assembly comprises the first gripper assembly and the second gripper assembly arranged left and right. The second gripper assembly includes a second slide and a second gripper arm.

[0024] The base 1 includes a front vertical plate 11, and the base 1 is also provided with a moving drive mechanism 5. The moving drive mechanism 5 is used to drive the feeding support clamp assembly to move in the front and back direction on the cutting equipment. The moving drive mechanism 5 can be a motor and a gear.
[0025] The first gripper assembly 2 includes a first slide block 21 and a first gripper arm 22. The first slide block 21 includes a first vertical plate 211, a first upper horizontal plate 212 and a first lower horizontal plate 213. The first upper horizontal plate 212 and the first lower horizontal plate 213 are respectively fixed to the upper rear side and the lower rear side of the first vertical plate 211. The first vertical plate 211 is spaced apart on the front side of the front vertical plate 11.

The rear side of the first lower horizontal plate 213 is slidably connected to the lower side of the front vertical plate 11. The first gripper arm 22 is located on the front side of the first vertical plate 211.
[0026] The first gripper assembly 2 and the second gripper assembly 3 are arranged left and right. The second gripper assembly 3 includes a second slide 31 and a second gripper arm 32. The second slide 31 includes a second vertical plate 311, a second upper horizontal plate 312 and a second lower horizontal plate 313.

The rear side of the second upper horizontal plate 312 is slidably connected to the upper side of the front vertical plate 11. The rear side of the second lower horizontal plate 313 is slidably connected to the lower side of the front vertical plate 11. The second gripper arm 32 is located on the front side of the second vertical plate 311.
[0027] The gripper drive mechanism 4 is located on the front side of the front vertical plate 11. The gripper drive mechanism 4 is located between the front vertical plate 11 and the first vertical plate 211 and the second vertical plate 311. The gripper drive mechanism 4 is located between the first upper horizontal plate 212 and the first lower horizontal plate 213 and between the second upper horizontal plate 312 and the second lower horizontal plate 313. The gripper drive mechanism 4 is connected to the first vertical plate 211 and the second vertical plate 311 in a transmission connection. The gripper drive mechanism 4 can drive the first gripper assembly 2 and the second gripper assembly 3 to move closer to each other or further away from each other.
[0028] The base 1 is equipped with a first gripper assembly 2, a second gripper assembly 3, and a gripper drive mechanism 4. The gripper drive mechanism 4 can drive the first gripper assembly 2 and the second gripper assembly 3 to move closer or further apart, so that the first gripper arm 22 and the second gripper arm 32 can clamp the rear end of the workpiece or release the workpiece. When the rear end of the workpiece is clamped, the feeding support clamp assembly can push the workpiece forward for cutting. The first gripper arm 22 and the second gripper arm 32 can clamp the workpiece by moving closer to each other on the outside of the workpiece, or they can spread apart and clamp the workpiece by moving further apart on the inside of the workpiece.
[0029] The first gripper assembly 2, the second gripper assembly 3, and the gripper drive mechanism 4 are all located on the front side of the front vertical plate 11 of the base 1.

The second slide 31 is provided with a second upper horizontal plate 312 and a second lower horizontal plate 313 that span over the gripper drive mechanism 4 and are slidably connected to the base 1. This allows the upper and lower rear sides of the first gripper assembly 2 and the upper and lower rear sides of the second gripper assembly 3 to be subjected to force, thereby improving the overall structural strength. The structure is relatively simple and can be used for clamping and pushing medium and heavy workpieces. Moreover, it allows the force application point of the gripper drive mechanism 4 to be closer to the first vertical plate 211 and the second vertical plate 311, making the movement of the first gripper assembly 2 and the second gripper assembly 3 smoother.
[0030] In some specific embodiments, the gripper drive mechanism 4 includes a drive cylinder 41, a first rack 42, a second rack 43, and a drive gear 44. The drive cylinder 41 is fixed to the front side of the front vertical plate 11. The first rack 42 and the second rack 43 both extend in the left-right direction and are arranged vertically. The first rack 42 is fixedly connected to the rear side of the first vertical plate 211, and the second rack 43 is fixedly connected to the rear side of the second vertical plate 311. The piston rod of the drive cylinder 41 is connected to the first vertical plate 211 or the second vertical plate 311. The drive gear 44 is rotatably connected to the base 1 and is located between the first rack 42 and the second rack 43. The first rack 42 and the second rack 43 are both meshed with the drive gear 44.
[0031] The first rack 42 and the second rack 43 mesh with the upper and lower sides of the drive gear 44, so that the movement direction of the first rack 42 is opposite to that of the second rack 43. When the drive cylinder 41 drives the first vertical plate 211 or the second vertical plate 311, the first gripper assembly 2 and the second gripper assembly 3 can be driven to move closer or further away from each other, which simplifies the drive structure.
[0032] Furthermore, the first rack 42, the second rack 43, and the drive gear 44 are all located on the front side of the drive cylinder 41. The front side of the front vertical plate 11 is fixedly connected to the mounting block 121, which is located on the lower side of the drive cylinder 41. The upper side of the front side of the mounting block 121 is fixedly connected to the mounting vertical block 122. The drive gear 44 is located on the rear side of the mounting vertical block 122 and is rotatably connected to it. The first vertical plate 211 and the second vertical plate 311 are respectively located on the left and right sides of the mounting vertical block 122.
[0033] A horizontal mounting block 121 and a vertical mounting block 122 are installed on the front side of the front vertical plate 11. The drive gear 44 can be installed by the horizontal mounting block 121 and the vertical mounting block 122, making the overall structure of the gripper drive mechanism 4 more compact.
[0034] Furthermore, a mounting protrusion 123 is provided on the upper rear side of the mounting vertical block 122, and a rack limiting groove 124 is provided on the upper side of the mounting horizontal block 121 and the lower side of the mounting protrusion 123. The first rack 42 and the second rack 43 are respectively slidably connected in the two rack limiting grooves 124.
[0035] The rack limiting groove 124 can limit the front and rear positions of the first rack 42 and the second rack 43 on the suspended side, thereby improving the rigidity of the overall structure.
[0036] In some specific embodiments, a first upper sliding groove 2121 is provided on the lower rear side of the first upper horizontal plate 212, and a second upper sliding groove 3121 is provided on the lower rear side of the second upper horizontal plate 312. The first upper sliding groove 2121 and the second upper sliding groove 3121 are engaged with the upper end of the front vertical plate 11 and are slidably connected. A first lower sliding groove 2131 is provided on the upper rear side of the first lower horizontal plate 213, and a second lower sliding groove 3131 is provided on the upper rear side of the second lower horizontal plate 313. The first lower sliding groove 2131 and the second lower sliding groove 3131 are engaged with the lower end of the front vertical plate 11 and are slidably connected.
[0037] The first upper sliding groove 2121 and the second upper sliding groove 3121 are engaged at the upper end of the front vertical plate 11, and the first lower sliding groove 2131 and the second lower sliding groove 3131 are engaged at the lower end of the front vertical plate 11. This structure has high strength and meets the mechanical performance requirements for clamping and pushing large workpieces.
[0038] In some specific embodiments, a first height adjustment structure is provided between the first clamping arm 22 and the first vertical plate 211, which can adjust the height position of the first clamping arm 22 on the first vertical plate 211. A second height adjustment structure is provided between the second clamping arm 32 and the second vertical plate 311, which can adjust the height position of the second clamping arm 32 on the second vertical plate 311. By adjusting the height of the first clamping arm 22 and the second clamping arm 32, workpieces of different sizes and shapes can be clamped.
[0039] Furthermore, the front side of the first vertical plate 211 is provided with a T-shaped groove 2111 extending in the vertical direction, and a locking nut is provided in the T-shaped groove 2111. The first clamping arm 22 is provided with a connecting hole 221. The connecting hole 221 and the locking nut are locked and fixed by a locking screw. The first height adjustment structure includes a T-shaped groove 2111, a locking nut, a connecting hole 221 and a locking screw.
[0040] The locking screw can pass through the connecting hole 221 and be threaded into the locking nut. The locking nut can move up and down within the T-slot 2111 to adjust its position. Tightening the locking screw can lock and fix the height of the first clamping arm 22, enabling manual height adjustment. The structure of the second height adjustment structure can be the same as that of the first height adjustment structure. In other embodiments, the first height adjustment structure can also adopt other manual or automatic height adjustment structures.
[0041] Furthermore, the first height adjustment structure also includes an adjustment screw 24, an adjustment through hole is provided on the front side of the first upper horizontal plate 212, an adjustment screw hole is provided on the first clamping arm 22, and the adjustment screw 24 passes through the adjustment through hole and is threadedly connected to the adjustment screw hole.
[0042] When it is necessary to adjust the height of the first clamping arm 22, first loosen the locking screw. Since the screw head of the adjusting screw 24 is on the upper side of the first adjusting through hole, the adjusting screw 24 can pull the first clamping arm 22 to prevent it from falling down. And by rotating the adjusting screw 24, the height of the first clamping arm 22 can be adjusted, making the adjustment more convenient.
