Description

Technical Field

[0001] The utility model belongs to the technical field of instrument processing and relates to a CNC processing center workbench. Background Art

[0002] Computer numerical control machine tools (abbreviated as CNC) are automated machine tools equipped with a program control system that can logically process programs specified by control codes or other symbolic instructions and decode them to enable the machine tool to move and process parts. CNC is mainly used for large-scale processing of parts, and its processing methods include turning outer circles, boring holes, turning planes, etc. It can be programmed and is suitable for mass production. The production process has a high degree of automation and is widely used in the automotive, aerospace and military industries. Compared with ordinary machine tools, CNC has high processing accuracy, stable processing quality, can perform multi-coordinate linkage, and can process parts with complex shapes. When the processed parts are changed, only the CNC program needs to be rewritten, which can save production preparation time.

[0003] The existing machining center worktable structure, when processing mechanical parts, is mainly clamped by clamping blocks set at both ends. Such clamping has high stability when clamping metal sheet parts, but it is difficult to meet the requirements when clamping vertically placed and high metal sheet parts, and needs to be improved. Summary of the invention

[0004] The purpose of the utility model is to provide a CNC machining center workbench to solve the problems raised in the above background technology.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A CNC machining center workbench includes a workbench plate, a first clamping mechanism, and a second clamping mechanism. The first clamping mechanism and the second clamping mechanism are respectively arranged on both sides of the workbench plate. The first clamping mechanism and the second clamping mechanism are composed of a swing arm, a support seat, a first clamping arm and a second clamping arm. One end of the swing arm is fixedly connected to the support seat, and a traction slide groove is provided inside the support seat. Two screw slides are slidably connected inside the traction slide groove, and one side of the two screw slides is respectively connected to the first clamping arm and the second clamping arm.

[0007] In the above-mentioned CNC machining center workbench, a displacement groove is opened on the side of the workbench plate, and a displacement slide is slidably connected inside the displacement groove. The bottom side of the displacement slide is movably connected to one end of the swing arm through a rotating shaft.

[0008] In the above-mentioned CNC machining center workbench, a limiting hole is provided at the top of the displacement slide, and a locking screw is threadedly connected to one side of the bottom of the swing arm, and the locking screw cooperates with the limiting hole.

[0009] In the above-mentioned CNC machining center workbench, a ball screw is movably arranged inside the traction slide, and both ends of the ball screw are threadedly sleeved with two screw slide seats.

[0010] In the above-mentioned CNC machining center workbench, one end of the support seat is fixedly connected to a traction motor, and the output end of the traction motor is fixedly connected to one end of the ball screw.

[0012] Compared with the prior art, the advantages of the CNC machining center workbench of the utility model are:

[0013] The present application arranges a movable first clamping mechanism and a second clamping mechanism on both sides of the work table. The first clamping mechanism and the second clamping mechanism can be placed flat on the supporting end surfaces on both sides of the work table and locked by means of a locking screw. In this way, when the metal sheet is placed flat on the work table, it can be clamped and fixed by means of the first clamping arm and the second clamping arm on both sides. When the metal sheet is placed vertically on the work table, the first clamping mechanism and the second clamping mechanism can be rotated to raise the two clamping mechanisms and slide to the two ends of the metal sheet, and then locked by means of a locking screw. The two ends of the vertically placed metal sheet can be clamped and fixed by means of the first clamping arm and the second clamping arm. The diversified fixing methods are more adaptable when processing metal sheets. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] A CNC machining center workbench includes a workbench plate 1, a first clamping mechanism 2, and a second clamping mechanism 3.

Two lead screw slides 8 are slidably connected inside the traction slide groove 7. One side of the two lead screw slides 8 is respectively connected to the first clamping arm 11 and the second clamping arm 12.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model is a CNC machining center workbench. Specifically, a displacement slide groove is opened at the side position of the workbench plate 1, and a displacement slide plate 4 is slidably connected inside the displacement slide groove. The bottom side of the displacement slide plate 4 is movably connected to one end of a swing arm 5 through a rotating shaft.
