Description

TECHNICAL FIELD

[0001] The utility model relates to the field of machining, especially a workpiece supporting mechanism and its supporting and leveling device. BACKGROUND

[0002] In machining, it is often necessary to support workpieces on a workbench to meet the height requirement of a tool or to adjust the height of the workpiece to meet the positional relationship between workpieces when machining in cooperation with other workpieces (for example, when assembling two workpieces to machine holes simultaneously under the condition of a determined positional relationship).

[0003] In the above-mentioned supporting method for workpieces, the height of the workpiece can only be adjusted by a certain number of shims, which is not applicable in situations requiring high accuracy in height adjustment.

[0004] Therefore, there is a need for a technical solution to address the technical problem that the height of a workpiece cannot be adjusted by traditional supporting shims, the workpiece cannot be supported to a specific height, the workpiece cannot be stably supported in the case of deformation of the workpiece, and the machining quality is affected. SUMMARY

[0005] The utility model aims to overcome the technical problem that the height of a workpiece cannot be adjusted by traditional supporting shims, the workpiece cannot be supported to a specific height, the workpiece cannot be stably supported in the case of deformation of the workpiece, and the machining quality is affected, and provides a workpiece supporting mechanism and its supporting and leveling device.

[0006] In a first aspect, the utility model provides a workpiece supporting mechanism, which comprises a guide block, a sliding block, and a pushing component.

[0007] The utility model provides a workpiece supporting mechanism, which comprises a guide block, a sliding block, and a pushing component.

[0008] Preferably, the pushing component is an adjusting bolt, one end of which is provided with a limiting nut, the inclined surface is provided with an adjusting hole, the included angle between the adjusting hole and the inclined surface is α, 0°<α<90°, the sliding block is provided with a first connecting hole, the end of the adjusting bolt away from the limiting nut is connected with the adjusting hole through the first connecting hole, and a gap is arranged between the adjusting bolt and the inner wall of the first connecting hole.

[0009] During further rotation of the adjusting bolt in the adjusting hole, the limiting nut at the end of the adjusting bolt generates a pushing force on the side of the sliding block, the pushing force generates a pushing force in the direction of the inclined surface, thereby driving the sliding block to move along the inclined surface of the guide block, and the adjusting bolt moves in the gap between the adjusting bolt and the inner wall of the first connecting hole, thereby realizing fine adjustment of the height of the top surface of the sliding block.

[0010] Preferably, the first connecting hole is provided with a first countersunk hole at one end of the side surface of the sliding block.

[0011] The limiting nut at the end of the adjusting bolt can be embedded in the first countersunk hole, so as to increase the stroke of the adjusting bolt, thereby increasing the adjustment range of the height of the top surface of the sliding block.

[0012] Preferably, the guide block is provided with a plurality of second connecting holes, and the second connecting holes are provided with connecting bolts.

[0013] The end of the connecting bolt is inserted into the second connecting hole and connected with the workbench, so as to realize detachable connection of the guide block with the workbench, ensure the position of the entire supporting mechanism on the workbench, and also make it easier to disassemble the supporting mechanism when the supporting mechanism is not needed.

[0014] Preferably, the second connecting hole is arranged on the inclined surface, the inclined surface is provided with a plurality of second countersunk holes, and the second countersunk holes are arranged in one-to-one correspondence with the second connecting holes.

[0015] Arranging the second connecting hole on the inclined surface can maximize the reduction of the width of the guide block, reduce the interference of the guide block with surrounding tooling and workpieces during use, and arranging a countersunk hole at one end of the second connecting hole close to the inclined surface can install the nut at the end of the connecting bolt, so as to avoid interference of the connecting bolt with the sliding block on the inclined surface.

[0016] Preferably, the sliding block is provided with a limiting block on each side, and the abutting surface and the two limiting blocks enclose a limiting groove with a width adapted to the width of the guide block.

[0017] The sliding block is clamped on the guide block through the limiting groove, and the guide block plays a guiding role on the sliding block, so that the sliding block can always maintain a correct posture for sliding, and the sliding block is prevented from being deflected to both sides.

[0018] Preferably, the top surface of the sliding block is provided with a sunken area.

[0019] Preferably, the top surface of the sliding block is provided with a plurality of mounting screw holes, and at least one of the mounting screw holes is provided with a supporting screw rod.

[0020] When the workpiece has a large-area flat bottom surface, the sliding block can support the workpiece, but when the workpiece is small and the bottom surface has longitudinal and transverse intersecting ribs, the commonly used sliding block cannot effectively support the workpiece. Therefore, the supporting screw rod arranged on the top surface of the sliding block can effectively support the workpiece when the bottom surface to be supported is small, and the application range is wider.

[0021] Preferably, the supporting screw rod is provided with a rotating disc, and the rotating disc is arranged around the supporting screw rod.

[0022] The rotating disc can be rotated to drive the supporting screw rod to rotate, so that the installation, dismounting or height adjustment of the supporting screw rod can be realized, and the rotation of the supporting screw rod is more convenient and labor-saving.

[0023] Preferably, a pressing nut is arranged on the supporting screw rod, and the pressing nut is used to abut against the top surface of the sliding block.

[0024] The pressing nut abuts against the top surface of the sliding block, so that the supporting screw rod can be prevented from loosening or falling off during machining.

[0025] In another aspect, the utility model also provides a workpiece supporting and leveling device, which comprises a base, and a plurality of workpiece supporting mechanisms as described above are arranged on the base.

[0026] The workpiece supporting and leveling device uses the corresponding supporting mechanisms arranged on the base according to the shape of the bottom surface of the workpiece to support each position of the bottom surface of the workpiece, and the sliding block moves along the inclined surface of the guide block, so that the device can meet the demand of different supporting heights and provide stable support for the workpiece when the workpiece is deformed, thereby ensuring the machining quality.

[0027] Compared with the prior art, the utility model has the advantages of:

[0028] The supporting mechanism comprises a guide block with an inclined surface and a sliding block, the sliding block moves along the inclined surface under the action of the pushing component, so that the height of the top surface of the sliding block is changed, the demand of different supporting heights can be met, and when the workpiece is deformed, the height of the top surface of the sliding block can be finely adjusted through the movement of the sliding block, so that the bottom surface of the workpiece can be stably supported.

[0046] In use, the guide block 1 is installed on the workbench, the slider is attached to the inclined surface 11 of the guide block 1 through the attachment surface 21, and under the pushing of the pushing component, the slider 2 slides along the inclined surface 11 of the guide block 1, thereby changing the height of the top surface of the slider 2, and further enabling the slider 2 to adapt to the requirements of different support heights, and when the workpiece is deformed, the height of the top surface of the slider 2 can also be fine-tuned through the movement of the slider 2, so that the bottom surface of the workpiece can be stably supported.

[0047] The pushing component is an adjusting bolt 3, one end of the adjusting bolt 3 is provided with a limiting nut 31, the inclined surface 11 is provided with an adjusting screw hole 12, the included angle between the adjusting screw hole 12 and the inclined surface 11 is α, 0°<α<90°, and in this example, α is preferably 15°, the slider 2 is provided with a first connecting hole 22, the end of the adjusting bolt 3 away from the limiting nut 31 penetrates through the first connecting hole 22 and is connected with the adjusting screw hole 12, the diameter of the first connecting hole 22 is larger than the diameter of the adjusting screw hole 12 and the diameter of the adjusting bolt 3, so that after the adjusting bolt 3 is installed, there is a gap 221 between the adjusting bolt 3 and the inner wall of the first connecting hole 22, and during the further rotation of the adjusting bolt 3 in the adjusting screw hole 12, the limiting nut 31 at the end of the adjusting bolt 3 generates a pushing force on the side of the slider 2, which generates a pushing force in the direction of the inclined surface 11, thereby driving the slider 2 to move along the inclined surface 11 of the guide block 1, and further realizing the fine adjustment of the height of the top surface of the slider 2.

[0048] The slider 2: the first connecting hole 22 is provided with a first countersunk hole 23 at one end of the side surface of the slider 2, the diameter of the first countersunk hole 22 is larger than the diameter of the limiting nut 31, so that the limiting nut 31 has sufficient space to move in the first countersunk hole 23, the limiting nut 31 at the end of the adjusting bolt 3 can be embedded in the first countersunk hole 23, which can increase the stroke of the adjusting bolt 3, thereby increasing the adjustment range of the height of the top surface of the slider 2, and the slider 2 is provided with a limiting block 24 on each side, the attachment surface 21 and the two limiting blocks 24 form a limiting groove with a width adapted to the width of the guide block 1, the slider 2 is clamped on the guide block 1 through the limiting groove, and the guide block 1 plays a guiding role on the slider 2, so that the slider 2 can always maintain the correct posture to slide, avoiding the deflection of the slider 2 to both sides.

[0050] Example 2

[0051] like Figure 5 As shown, in this embodiment, the difference from embodiment 1 is that the top surface of the slider 2 is provided with a plurality of mounting screw holes 25, and at least one mounting screw hole 25 is provided with a support screw 4.

[0052] When the workpiece has a large flat surface at the bottom, the slider 2 can provide support.

[0054] Furthermore, a clamping nut 5 is fitted on the support screw 4. The clamping nut 5 is used to abut against the top surface of the slider 2, which can play a role in preventing the support screw 4 from loosening or falling off during the processing.

[0055] Example 3

[0056] like Figure 6 As shown, the difference between this embodiment and embodiment 1 is that the top surface of the slider 2 is provided with a recessed area 26.

[0057] When there is a sunken structure on the bottom surface of the workpiece, the sunken structure interferes with the top surface of the slider 2. In this embodiment, a corresponding sunken area 26 is set on the top surface of the slider 2. The sunken area 26 can be in the form of a step, hole, groove or cavity, etc., to avoid the sunken structure at the bottom of the workpiece.

[0058] Embodiment 4

[0059] As Figure 7 shown in the embodiment, a workpiece support leveling device is provided, comprising a base 6, wherein a plurality of workpiece support mechanisms as any one of embodiments 1-3 are arranged on the base 6.
