Description

Technical Field

[0001] This utility model relates to the field of machine tools, specifically to a feeding and pushing device for a vertical machining center. Background Technology

[0002] A vertical machining center is a machining center whose spindle axis is set perpendicular to the worktable. It is mainly suitable for machining complex parts such as plates, discs, molds, and shells. Vertical machining centers can perform milling, boring, drilling, tapping, and thread cutting operations. A minimum of three-axis two-linkage machining center can achieve three-axis three-linkage. Some can even perform five-axis or six-axis control.

[0003] The existing technology has the following problems:

[0004] Existing vertical machining centers can only adjust the position of the workpiece table in the front-back and left-right directions. When machining larger workpieces, it is often necessary to use a hoisting method to assist in clamping and picking up the workpiece. The overall operation is cumbersome and inconvenient.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, this utility model provides a feeding and pushing device for a vertical machining center, including a base, a symmetrical track on the base, a reciprocating sliding slide mounted on the track, and a support table connected to the top of the slide;

[0009] The adjustment mechanism includes a support installed in the workpiece table, a screw and a guide rod installed between the two sets of supports, the screw being controlled by a lead screw motor to rotate, and a lead screw slide seat that slides along the guide rod is sleeved on the outside;

[0010] The internal support mechanism includes a shaft seat mounted on the lead screw slide and a rotating shaft seat mounted on the workpiece table. A rotatable adjusting seat is fitted outside the shaft seat, and a protruding support rod is mounted on the adjusting seat. A rotatable rotating frame is fitted outside the rotating shaft seat, and the other end of the support rod and the rotating frame is connected to the workpiece table.

[0011] Preferably, the workpiece table tilts to one side as the support rod extends.

[0012] Preferably, when the workpiece stage is parallel to the support platform, the support rod is relatively parallel to the workpiece stage.

[0013] Preferably, the edge of the workpiece stage is inclined, and a rotatable pulley system is installed inside it.

[0014] Preferably, the workpiece platform is symmetrically provided with raised guardrails.

[0015] Preferably, the support platform has a plurality of support columns inside, and the top of the support columns is attached to the lower part of the workpiece table.

[0016] The above-mentioned technical solution of this utility model has the following beneficial technical effects: by cooperating with the adjusting mechanism and the inner support mechanism, the tilt angle of the workpiece table can be changed. The workpiece table with one side tilting facilitates the movement of the workpiece after clamping and picking up the workpiece.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0023] like Figure 1-3 As shown, the present invention proposes a feeding and pushing device for a vertical machining center, including a base 11, a symmetrical track 12 on the base 11, a reciprocating sliding slide 13 installed on the track 12, and a support platform 14 connected to the top of the slide 13.

[0024] The adjustment mechanism includes a support 21 installed in the workpiece table 4. A screw 22 and a guide rod 23 are installed between the two sets of supports 21. The screw 22 is controlled to rotate by the lead screw motor 24, and a lead screw slide 25 that slides along the guide rod 23 is sleeved on the outside.

[0025] The internal support mechanism includes a shaft seat 31 mounted on the lead screw slide 25 and a rotating shaft seat 34 mounted on the workpiece table 4. A rotatable adjusting seat 32 is sleeved on the outside of the shaft seat 31, and a protruding support rod 33 is mounted on the adjusting seat 32. A rotatable rotating frame 35 is sleeved on the outside of the rotating shaft seat 34. The other end of the support rod 33 and the rotating frame 35 is connected to the workpiece table 4.

[0026] It should be noted that when the workpiece table 4 is parallel to the support table 14, the support rod 33 is relatively parallel to the workpiece table 4, ensuring that the workpiece table 4 is in a horizontal state for workpiece processing.

[0027] In this embodiment, when clamping is required, the slide block 13 slides on the track 12, moving the support platform 14 to one end of the base 11. Through the operation of the adjustment mechanism, the lead screw motor 24 drives the screw 22 to rotate, causing the lead screw slide block 25 to slide on the guide rod 23. At this time, the inner support mechanism starts to operate, and the adjustment seat 32 connected to the support rod 33 rotates on the shaft platform 31. The rotating frame 35 on one side rotates on the rotating shaft seat 34. At this time, the workpiece platform 4 tilts on one side as the support rod 33 extends. The tilted end face can assist the workpiece in being pushed to the upper part of the workpiece platform 4. The workpiece can be pushed without hoisting, which facilitates the clamping of the workpiece. After clamping, the workpiece platform 4 with the workpiece clamped is reset to the initial position through the cooperation of the adjustment mechanism and the inner support mechanism, and the workpiece can be processed.

[0028] To facilitate the pushing of the workpiece on the workpiece stage 4, the edge of the workpiece stage 4 is inclined, and a rotatable pulley group 6 is installed inside. During the pushing process, the pulleys of the pulley group 6 rotate when they contact the workpiece, which plays a role in pushing.

[0029] To further protect the workpiece table 4, raised guardrails 5 are symmetrically arranged on the workpiece table 4. The raised guardrails surround the workpiece table 4, preventing flying debris from falling to the outside.

[0030] To ensure the stability of the workpiece table 4 during processing, the support table 14 is further equipped with several support columns 7 inside. The top of the support columns 7 is attached to the lower part of the workpiece table 4. The support columns 7 provide multi-point support for the workpiece table 4, ensuring that the workpiece table 4 is in a horizontal state.

[0031] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
