Description

Technical Field

[0001] The utility model relates to a portable woodworking engraving machine with fast tool change, belonging to the field of woodworking engraving machines. Background Art

[0002] In the woodworking engraving industry, traditional woodworking engraving machines often need to replace the engraving tools during the processing due to the wear of the engraving tools or the need to replace different types of tools to meet different engraving needs.

[0003] However, some existing woodworking engraving machines have obvious deficiencies in the tool changing process. Specifically, the tools of woodworking engraving machines are generally fixed and connected by screws. Although this fixing method is stable, it brings inconvenience in actual operation. The screw fixing method requires the use of special tools such as screwdrivers or wrenches when installing or removing the tools, which not only increases the complexity of the operation, but also requires the operator to carry these tools with him, adding an extra burden. In an emergency, if the tools are lost or damaged, it will directly lead to the inability to change the tools. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 A portable woodworking engraving machine with quick tool change comprises an engraving machine connecting frame 1 and a tool 2. The upper surface of the tool 2 is provided with a connecting structure for connecting to the engraving machine connecting frame 1.

[0025] like Figure 1 The connection structure shown includes an insert block 3 fixedly connected to the upper surface of the engraving machine connecting frame 1, a fixing plate 4 fixedly connected between the inner top wall and the inner bottom wall of the insert block 3, an elastic telescopic rod 5 fixedly connected to the left and right sides of the fixing plate 4 respectively, a connecting plate 6 fixedly connected to the piston rod of the elastic telescopic rod 5, and a positioning block 7 fixedly connected to the other side of the connecting plate 6.

[0026] A reinforcing component is provided on the inner side of the engraving machine connecting frame 1 to make the connection more secure.

[0027] It should be noted that two sliding rods 8 are slidably connected to the inner side of the connecting plate 6, and the two sliding rods 8 are respectively located above and below the elastic telescopic rod 5, the left end of the left sliding rod 8 is fixedly connected to the inner left side wall of the plug block 3, and the right end of the left sliding rod 8 is fixedly connected to the fixed plate 4, the left end of the right sliding rod 8 is fixedly connected to the fixed plate 4, and the right end of the right sliding rod 8 is fixedly connected to the inner right side wall of the plug block 3.

[0028] The left and right walls of the insert block 3 are both provided with through openings, the left and right walls of the engraving machine connecting frame 1 are both provided with positioning openings, and the through opening on the left is connected to the positioning opening on the left, and the through opening on the right is connected to the positioning opening on the right.

[0029] The reinforcement component includes a mounting plate 9 fixedly connected between the inner left wall and the inner right wall of the engraving machine connecting frame 1, a threaded rod 10 rotatably connected to the upper surface of the mounting plate 9, a threaded block 11 threadedly connected to the outer side of the threaded rod 10, a slider 12 fixedly connected to the left and right sides of the threaded block 11 respectively, and a positioning bolt 13 fixedly connected to the bottom of the slider 12.

[0030] A magnet sheet 14 is fixedly connected to the bottom of the mounting plate 9 , and an iron block 15 matching the magnet sheet 14 is fixedly connected to the upper surface of the insert block 3 .

[0031] The top end of the threaded rod 10 passes through the thread groove of the threaded block 11 and the inner top wall of the engraving machine connecting frame 1 in sequence, and the top end of the threaded rod 10 is fixedly connected with a twist cap 16 .

[0033] The working principle of the above embodiment is:

[0034] First, insert the plug block 3 into the inner side of the engraving machine connecting frame 1 until the iron block 15 of the plug block 3 is attracted to the magnet sheet 14. At this time, the plug block 3 is located on the inner side of the engraving machine connecting frame 1, and the elastic telescopic rod 5 loses the extrusion. Then, under the characteristics of elastic reset, the elastic telescopic rod 5 drives the connecting plate 6 to move. During the movement of the connecting plate 6, the sliding rod 8 guides the movement direction of the connecting plate 6 to ensure that the movement of the connecting plate 6 will not deviate. After that, the connecting plate 6 drives the positioning block 7 to penetrate the inner side of the bayonet of the engraving machine connecting frame 1, thereby completing the preliminary installation;

[0035] To ensure the stability of the installation, the twist cap 16 is then rotated to drive the threaded rod 10 to rotate, and the threaded rod 10 then drives the threaded block 11 to move downward. The threaded block 11 drives the slider 12 to move downward during the downward movement, and the slider 12 drives the positioning bolt 13 to be inserted into the socket of the positioning block 7 during the downward movement, thereby further positioning the positioning block 7 and enhancing the stability of the connection.
