Description

Technical Field

[0001] The utility model relates to the technical field related to clamps, in particular to a clamp for metal surface treatment. Background Art

[0002] Metal generally refers to a type of material that has a unique luster (i.e., strong reflection of visible light) but is opaque, ductile, and conductive to heat and electricity. A clamp is required when painting, polishing, chamfering, and other treatments are performed on the metal surface.

[0003] For example, the utility model patent with patent application number 202222537983.5 provides a fixture that is easy to disassemble and install, including a processing table and a mounting plate, a mounting plate is arranged on the top of the processing table, a fixture body is arranged inside the mounting plate, and the mounting plate is connected to the processing table through four groups of locating pins; a rotating column, a spring, a limit block and a movable column are arranged inside the locating pin from top to bottom, and a handle is arranged on the top of the rotating column. Compared with the existing fixtures that are easy to disassemble and install, the overall convenience, adjustability and practicality of the fixture that is easy to disassemble and install can be improved through design. However, this fixture uses a clamping block to clamp the workpiece, and cannot stably clamp columnar workpieces. It is necessary to replace a suitable clamping block. However, the machine needs to be stopped to replace the clamping block, which will cause a waste of time. Utility Model Content

A supplementary block 82 is connected to the top of the assembly plate 87 through the connecting component 6, and the supplementary block 82 can complement the clamping groove 89 to form a clamping plane. An L-shaped connecting plate 88 connected to the piston end of the telescopic rod 85 is installed on one side of the bottom of the assembly plate 87. The clamping groove 89 can be a V-shaped groove used in this embodiment, which can realize the clamping of columnar workpieces. The supplementary block 82 is a triangular block that can complement the V-shaped groove, so that the clamping block 81 and the supplementary block 82 together form a plane that can clamp flat parts. The clamping groove 89 can also be an arc groove, and the clamping block 81 can also be in the shape of an arc at one end and a plane at the other end.

[0026] The top of the clamping block 81 and the bottom of the supplementary block 82 are both provided with connecting holes, in which a clamping rod 83 is fixed. The clamping block 81 and the supplementary block 82 can be installed by cooperating with the L-shaped clamping hole 641 .

[0027] Among them, the connecting component 6 includes a rotating tube 64 and a fixed sleeve 61 which is sleeved on the outside of the rotating tube 64 and rotatably connected to the rotating tube 64 through a rotating member 62. The rotating member 62 can be a bearing. An L-shaped clamping hole 641 that cooperates with the clamping rod 83 is opened at one end of the fixed sleeve 61. The gantry 2 and the assembly plate 87 are both provided with through holes for installing the fixed sleeve 61. A rotating handle 63 is installed at the other end of the rotating tube 64, which can facilitate the rotation of the rotating tube 64.

[0028] Align the L-shaped clamping hole 641 and the clamping rod 83. After the clamping rod 83 enters the L-shaped clamping hole 641, move the rotating tube 64 into the connecting hole until it can no longer move. Rotate the rotating tube 64 to complete the installation of the clamping block 81 or the supplementary block 82.

Both ends of the middle hole 11 are connected with T-shaped through holes 13. The T-shaped through holes 13 play an avoidance role, enabling the assembly plate 87 to smoothly move up with the supplementary block 82 to supplement the clamping groove 89, and both the sliding through holes 12 and the middle hole 11 play a guiding role.

[0031] A buffer spring 7 is provided between the two L-shaped connecting plates 88 , and both ends of the buffer spring 7 are fixedly connected to the two L-shaped connecting plates 88 , respectively. The buffer spring 7 is used for buffering, thereby improving the stability of the L-shaped connecting plates 88 when moving.

[0033] During operation, the bidirectional driving module 4 is started, and the gantry 2 is driven via the T-shaped mounting plate 5, and then the clamping components 8 are driven to approach each other. The columnar workpiece can be clamped through the clamping groove 89 on the clamping block 81. When a flat workpiece needs to be clamped, the telescopic rod 85 moves up with the supplementary block 82 to supplement the clamping groove 89, forming a clamping plane that can clamp the flat workpiece, so that the flat workpiece can be clamped.
