Detailed Description

The following describes in detail embodiments of the present invention with reference to the accompanying drawings and examples.

As shown in fig. 1-4, the workbench of the present embodiment includes a fixing base 1, a pressing plate 2, a supporting bar 3 and a supporting beam 4. A plurality of support bars 3 are arranged in parallel, and two ends of each support bar 3 are respectively connected to two sides of the fixed seat 1; the upper ends of two sides of the fixed seat 1 are respectively connected with a pressing plate 2 for pressing and connecting two end parts of the supporting bar 3; the support beams 4 are arranged transversely to the bottom of the plurality of support bars 3 so that the support bars 3 are partially elevated in their supporting position. The joint of the fixed seat 1 and the support bar 3 is provided with a gap for fine adjustment of the support bar 3 along the length direction. One end of the supporting bar 3 is provided with a pressing inclined surface 31, and the pressing inclined surface 31 can be arranged at the upper part of the supporting bar 3 in the area where the end is pressed with the pressing plate 2, or arranged at the lower part of the supporting bar 3 in the area where the end is connected with the fixed seat 1.

Referring to fig. 3, taking the pressing inclined plane 31 located at the region where one end of the supporting bar is pressed against the pressing plate 2 as an example, when the workbench is assembled, the horizontal position of the supporting bar 3 is adjusted, the horizontal position of the pressing inclined plane 31 is offset accordingly, and accordingly, the longitudinal distance between the pressing inclined plane 31 and the pressing plate is changed, so that the pressing inclined planes 31 on different supporting bars 3 and the pressing plate 2 can be adjusted to the same height. When the crimping positions are adjusted to the same height, the pressing plate 2 corresponding to the end part of the supporting bar 3 is locked to the fixing seat 1, and the end part can be pressed on the fixing seat 1 by the pressing plate 2.

Simultaneously, because supporting beam 4 is with 3 local elevations of support bar, when the one end of support bar 3 received the decurrent pressure of clamp plate 2, the other end of support bar 3 can produce an ascending restoring force, and under the effect of this restoring force, the other end of support bar 3 supported with clamp plate 2 and leaned on, locked this clamp plate 2 to fixing base 1, then can compress tightly another end on fixing base 1. Both ends of the supporting strip 3 are pressed tightly, the position of the supporting strip in the vertical direction is kept stable, and meanwhile, the position of the supporting strip 3 in the horizontal direction can also be kept stable under the action of friction force between the other end of the supporting strip 3 and the pressing plate 2. The workpiece is placed on the stable supporting bar for processing, and the processing precision of the workpiece is guaranteed.

Referring to fig. 4, the manner of locating the crimping ramp 31 in the area where one end of the support bar is connected to the fixing base 1 is the same as the manner described above. At this moment, the horizontal displacement of the crimping inclined plane 31 is used for changing the installation height of the supporting bars 3 on the fixing seat 1, so that the upper end surfaces of different supporting bars 3 are aligned to the same plane, the height error of the supporting bars 3 is compensated, and the pressing plate 2 and the supporting bars 3 are abutted to be crimped.

Further, as shown in fig. 3 and 4, the other end of the supporting bar 3 may also be provided with a pressing slope 31 in the area where the other end of the supporting bar 3 is pressed against the pressing plate 2, and the pressing slope 31 abuts against the pressing plate 2 by the upward restoring force of the other end of the supporting bar 3. Meanwhile, the inclined direction of the pressing inclined surface 31 is set to satisfy the condition that the lateral pressure applied to the pressing inclined surface 31 is opposite to the lateral pressure applied to the pressing inclined surface 31 at the other end, for example, in fig. 4, the pressing inclined surface 31 at one end of the supporting bar 3 is applied with the leftward lateral pressure of the fixing base 1, the pressing inclined surface 31 at the other end is applied with the rightward lateral pressure of the pressing plate 2, and the lateral pressures applied to the two pressing inclined surfaces 31 are opposite. Adopt this structure lockable support bar 3 horizontal direction's position, further promote support bar 3's stability.

Specifically, as shown in FIGS. 3-5, crimp ramp 31 may be a ramp of an angular indentation or a ramp of an angular protrusion. When the crimping inclined plane 31 is an inclined plane of an angular notch located in the crimping area of the supporting bar 3 and the pressing plate 2, in order to realize crimping, the pressing plate 2 includes a connecting portion 21 and a bending portion 22, the connecting portion 21 is used for connecting the fixing seat 1, and the tail end of the bending portion 22 is crimped with the crimping inclined plane 31. When the pressure contact slope 31 is provided at another position or in another shape, the pressure plate 2 may have a flat plate structure, or may have the structure including the bent portion 22.

The connection mode of the supporting bar 3 and the fixing base 1 can be seen with reference to fig. 3-6. Fixing base 1 includes fixing base frame 11 and mounting panel 12, and mounting panel 12 is connected with fixing base frame 11, and the interval sets up a plurality of mounting grooves 121 on mounting panel 12, and the tip of a plurality of support bars 3 joint respectively in mounting groove 121 to install support bar 3 on fixing base 1. The mounting plate 12 may have a thickness such that the mounting groove 121 has a depth to provide a sufficient clearance for the support bar 3 to be adjusted in the horizontal direction.

Preferably, the fixing base 1 of the present embodiment further includes a connecting plate 13, and the mounting plate 12 is connected to the fixing base frame 11 through the connecting plate 13. At this time, it is possible to provide a certain thickness for the support bar 3 by providing the connection plate, and the mounting plate 12 is used only for clamping the support bar 3. The additional arrangement of the connecting plate 13 enables the mounting plate 12 to be processed more simply, so that the processing cost can be reduced, and meanwhile, the connecting plate 13 can be conveniently processed by adopting different materials, so that the mounting plate has better stress capability. The fixing seat frame 11, the mounting plate 12 and the connecting plate 13 are detachably connected through screws, and are easy to maintain and replace.

In other embodiments, the supporting beam 4 may also be disposed outside the fixing base 1, and the height thereof is adjusted by the legs, so that it can partially elevate the supporting beam 3. Compared with the way that the supporting beam 4 is arranged in the fixing seat 1, the present embodiment is more convenient for the installation and adjustment of the supporting beam. The two support beams 4 are arranged to partially elevate the support bars 3, so that the heights of the upper surfaces of the support bars 3 can be kept consistent; set up the draw-in groove and inlay the support bar 3 wherein, can further guarantee the stability of support bar 3 to reach the more stable support to the work piece.

Meanwhile, one side of the supporting strip 3, which is in contact with the workpiece, is provided with a saw-toothed structure 33, so that the workbench can be better matched with processing technologies such as laser cutting, drilling and the like. The machining process needs to be matched with air blowing to remove chips generated in machining at the first time, otherwise, the chips are possibly attached and accumulated at the cutting position, and the cutting quality is influenced. The zigzag structure 33 can provide a space for air flow to ensure the blowing effect, thereby improving the processing quality.
