Abstract
Description
Technical Field
[0001] The utility model relates to the field of engraving machines, in particular to a structure for sliding and locking an ejector beam of a rotary shaft of an engraving machine. Background Art
[0002] A four-axis engraving machine is a computer-controlled CNC machine tool with four axes of motion, typically three linear axes (X, Y, and Z) and one rotary axis (usually the A-axis). This machine can perform engraving, cutting, and drilling on a variety of materials, including wood, plastic, metal, stone, glass, ceramics, and resin. Four-axis engraving machines are characterized by their ability to engrave cylindrical or spherical objects, as well as process curved surfaces or curves.
[0003] When clamping materials of different lengths and sizes, the existing four-axis engraving machine needs to move the ejector beam of the fourth axis. After adjusting the required clamping length, the ejector beam is locked using the nut on the screw that runs through the ejector beam. A rotatable telescopic clamp is installed at the front end of the ejector beam, which is rotated to tighten and lock the workpiece. The traditional movement is to lay the track on the table. Since there is tool cooling water generated by carving stone and stone residues after carving on the table, it is easy for water to accumulate on the table and various processing residues to accumulate. It is easy for the guide rails to rust when exposed to water and for the residues to get stuck in the guide rails. Therefore, we propose an installation method in which the guide rails are installed on both sides of the bed, away from the table. The ejector beam is fixed by the nut on the screw that runs through the ejector beam. Since the adjustment distance is relatively long, adjusting the locking nut is time-consuming and labor-intensive. We propose a locking structure for the ejector beam of the engraving machine to complete the clamping of the workpiece. Utility Model Content
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and adapt to actual needs. A structure for sliding and locking the ejector beam of the rotating axis of an engraving machine is provided to solve the problem that, when the existing four-axis engraving machine is clamping materials of different lengths and sizes, the ejector beam of the fourth axis needs to be moved. In the traditional movement, the rail is laid on the table. Since the table is prone to water accumulation and various processing waste materials, the guide rail is easily stuck. In addition, the ejector beam is fixed by a nut on a screw that passes through the ejector beam. Since the adjustment distance is relatively long, it is time-consuming and laborious to adjust the locking nut.
[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is as follows: a structure for sliding and locking the ejector beam of the rotating axis of an engraving machine is designed, comprising an engraving machine body, rails are installed on both sides of the interior of the engraving machine body, L-shaped sliding plates are slidably connected to the surface of the rails, and the ejector beam is fixed between the two L-shaped sliding plates;
[0006] A rotatable clamping piece is installed at the front end of the ejector beam, which can tighten and lock the workpiece after rotation.
[0007] Preferably, a locking plate is installed on the outside of the track, and a plurality of locking holes are opened on the surface of the locking plate.
[0008] Preferably, the L-shaped sliding plate is provided with a through hole, and the through hole is aligned with the locking hole.
[0009] Preferably, one end of the locking member passes through the through hole and extends into the locking hole to lock the ejector beam.
[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] 1. The utility model combines rails, L-shaped sliding plates and ejector beams to set the rails on both sides of the machine bed. The L-shaped sliding plates drive the ejector beams to slide through the rails on both sides of the bed, thereby adjusting the length suitable for holding the workpiece. This solves the problem of the existing four-axis engraving machine needing to move the ejector beam of the fourth axis when clamping materials of different lengths. The traditional movement is to lay the rails on the table, which is prone to water accumulation and various processing residues on the table, which can easily get stuck on the guide rails.
[0012] 2. The utility model combines the locking plate body, the locking piece and the locking hole, so that the locking piece can pass through the through hole on the surface of the L-shaped sliding plate, and the locking piece can be extended into the locking hole to lock the ejector beam, thereby realizing rapid limit locking of the ejector beam.

[0016] The present invention is further described below with reference to the accompanying drawings and embodiments:
[0017] Example 1: A structure for sliding and locking the thimble beam of the rotary axis of an engraving machine, see Figures 1 to 2, including an engraving machine body 1, with tracks 2 installed on both sides of the interior of the engraving machine body 1, and L-shaped sliding plates 3 are slidably connected to the surface of the track 2, and a pin beam 4 is fixed between the two L-shaped sliding plates 3; a rotatable clamping part 5 is installed at the front end of the pin beam 4, which is rotated to tighten and lock the workpiece. Since the track 2 is set on both sides of the bed, the L-shaped sliding plate 3 can drive the pin beam 4 to slide along the track 2 on the side of the bed, thereby adjusting the length suitable for holding the workpiece, solving the problem of the existing four-axis engraving machine needing to move the pin beam 4 of the fourth axis when clamping materials of different lengths. The traditional movement is to lay the track 2 on the table, but the table is prone to water accumulation and various processing residues, and the guide rails are prone to rust.
[0018] For details, see Figure 2 A locking plate body 6 is installed on the outside of the track 2, and a plurality of locking holes 7 are opened on the surface of the locking plate body 6. When the ejector beam 4 needs to be locked, the through hole 8 on the surface of the L-shaped sliding plate 3 is aligned with the locking hole 7 on the surface of the locking plate body 6, and then the locking piece 9 is passed through the through hole 8 and extended into the locking hole 7 to achieve locking of the ejector beam 4.
[0019] For further information, see Figure 2 A through hole 8 is provided on the surface of the L-shaped sliding plate 3 , and a locking member 9 is passed through the through hole 8 .
[0020] It is worth noting that, see Figure 2 One end of the locking member 9 passes through the through hole 8 and extends into the locking hole 7 to lock the ejector beam 4.
[0021] When using a structure for sliding and locking the ejector beam of the rotating axis of an engraving machine, since the rails 2 are set on both sides of the bed, the L-shaped sliding plate 3 can drive the ejector beam 4 to slide along the rails 2 on both sides, thereby adjusting the length suitable for holding the workpiece. When the ejector beam 4 needs to be locked, the through hole 8 on the surface of the L-shaped sliding plate 3 is aligned with the locking hole 7 on the surface of the locking plate body 6, and then the locking piece 9 is passed through the through hole 8 and extended into the locking hole 7 to achieve locking of the ejector beam 4.
