Description

Technical Field

[0001] The utility model relates to the field of engraving machines, in particular to an engraving machine with a movable rotating shaft mechanism. Background Art

[0002] The fourth axis of the four-axis engraving machine is divided into three parts, including the rotary axis, the tailstock, and the tailstock support guide rail. When using the table surface for processing, the tip of the tailstock and the entire tailstock occupy part of the table space, which reduces the stroke that can be processed on the plane. In order to ensure that the processing is of sufficient size, the traditional method can only increase the length of the machine table; in addition, whether the tailstock support guide rail is fixed in the middle of the Z-axis stroke or on the table, it will cause interference and collision when the engraving machine spindle moves left and right for processing. In order to ensure that the processing is of sufficient size, the traditional method can only increase the left and right width of the machine, which increases the overall size and volume of the machine, increases the space occupied by the machine equipment, and increases the cost of production and processing, and has poor practicality. Utility Model Content

[0003] The purpose of the utility model is to provide an engraving machine with a movable rotating axis mechanism, which places the tailstock top on the columns on both sides through the slide rails on both sides of the support frame, so that the slide rails will not affect the left and right stroke of the engraving head. At the same time, the tailstock top can be pushed to the rear of the table and does not occupy the space of the table. There is no need to change the overall size of the machine equipment, which not only reduces the space occupied, but also saves costs and has better practicality.

[0004] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0005] An engraving machine with a movable rotating axis mechanism comprises a support frame, an engraving device is provided on the support frame through a displacement mechanism, a base is provided at one end of the support frame, a mounting seat is provided on the base for sliding through a guide rail, a rotating axis is rotatably provided on the mounting seat, slide rails are symmetrically provided on both sides of the support frame, a support plate is slidably provided between the two slide rails, a tailstock corresponding to the rotating axis is provided on the support plate, and a limiting device is provided on both the support plate and the mounting seat.

[0006] Furthermore, the limiting device of the support plate includes a push rod rotatably connected to both ends of the support plate, and the end of the push rod away from the support plate can contact the slide rail.

[0007] Furthermore, the limiting device of the mounting seat includes a sleeve that passes through the mounting seat, a limiting rod is inserted and slidably provided in the sleeve, and a lifting handle is rotatably connected to the sleeve, which drives the limiting rod to slide up and down, and the bottom end of the limiting rod can contact the base.

[0008] Furthermore, an anti-slip pad is provided at one end of the support rod that contacts the guide rail.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] This patent sets slide rails on the columns on both sides of the support frame, and hides the slide rails inside the support frame, so that the slide rails will not affect the left and right stroke of the engraving head, and there is no need to increase the left and right width of the machine to ensure that the processing is sufficient. At the same time, the support plate with the tailstock is placed on the two slide rails, so that the support plate can slide on the slide rails, and the tailstock can be pushed to the back of the table without occupying the space of the table. There is no need to increase the length of the machine table to ensure that the processing is sufficient, so there is no need to change the overall size of the machine equipment, which not only reduces the installation space occupied by the machine equipment, but also saves manufacturing costs and is more practical.

[0018] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0019] The present invention is an engraving machine with a movable rotating axis mechanism. The main structure includes a support frame 1. An engraving device 2 is provided on the support frame 1 through a displacement mechanism. The displacement mechanism can drive the engraving device 2 to move on the X, Y, and Z axes. The engraving device 2 and the displacement mechanism are common structural components in the prior art. The specific structural composition and principle are not described here. One end of the support frame 1 is provided with a base 3. A mounting seat 5 is provided on the base 3 for sliding through a guide rail 4. A rotating shaft 6 is provided on the mounting seat 5 so that the rotating shaft 6 can move horizontally along the guide rail 4. Slide rails 7 are symmetrically provided on both sides of the support frame 1 so that the slide rails 7 are suspended. In the middle of the Z-axis stroke, in order to solve the problem of collision and interference between the main spindle and the slide rail 7 when moving left and right, a support plate 8 is provided between the two slide rails 7 for sliding. A tailstock 9 corresponding to the rotating shaft 6 is provided on the support plate 8. A limiting device is provided on the support plate 8 and the mounting seat 5, which can fix the position of the support plate 8 and the mounting seat 5 after they move, so as to avoid the forward movement and collision of the tailstock 9 caused by accidental falling off during workpiece processing. When plane processing is performed, the rotating shaft 6 is slid back to the tail of the table, leaving some space so that the support plate 8 and the tailstock 9 can be retreated to the tail of the table, thereby solving the problem of limited forward and backward travel of the table during spindle plane processing.

[0020] Preferably, the limiting device of the support plate 8 includes a push rod 10 rotatably connected to both ends of the support plate 8, and the end of the push rod 10 away from the support plate 8 can contact the slide rail 7. When in use, the push rod 10 is lifted to move the support plate 8. When fixed, the push rod 10 is rotated downward so that the bottom end of the push rod 10 contacts the slide rail 7 and is squeezed and fixed on the slide rail 7, thereby fixing the support plate 8, thereby fixing the position of the tail stock 9, and avoiding the forward movement and collision of the tail stock 9 when the front end material accidentally falls off.

[0021] Preferably, the limiting device of the mounting seat 5 includes a sleeve 11 that passes through the mounting seat 5, and a limiting rod 12 is inserted and slidably provided in the sleeve 11. A lifting handle 13 is rotatably connected to the sleeve 11, and the lifting handle 13 drives the limiting rod 12 to slide up and down. This linkage structure belongs to a common connection structure in the prior art, that is, rotating the lifting handle 13 drives the limiting rod 12 to move vertically up and down. The specific structure is not described here and does not belong to the invention point of this patent. Those skilled in the art can choose it by themselves according to conventional technical means. The bottom end of the limiting rod 12 can contact the base 3. When the rotating shaft 6 is moved, the lifting handle 13 is lifted to drive the limiting rod 12 to move upward, and the rotating shaft 6 can be moved. Then, the lifting handle 13 is pressed to press the limiting rod 12 downward, so that the bottom end of the limiting rod 12 contacts the base 3, and the friction force is used to fix the position of the mounting seat 5, thereby fixing the position of the rotating shaft 6, which is more flexible and convenient.

[0022] Preferably, an anti-skid pad 14 is provided at the end of the push rod 10 that contacts the guide rail 4 to increase the friction between the push rod 10 and the slide rail 7, thereby playing an anti-skid role and better fixing the position of the support plate 8.

[0023] This patent does not require increasing the left and right widths of the machine to ensure that the processing reaches a sufficient size, nor does it require increasing the length of the machine table to ensure that the processing reaches a sufficient size. Therefore, there is no need to change the overall size of the machine equipment, which not only reduces the installation space occupied by the machine equipment, but also saves manufacturing costs and is more practical.
