Description

Technical Field

[0001] This utility model relates to the field of machining center technology, and in particular to a tool magazine mounting structure for a machining center. Background Technology

[0002] In related technologies, profile machining centers equipped with tool magazines typically mount the tool magazine on a gantry or crossbeam. However, when the spindle on the gantry or crossbeam moves along the X-axis, the tool magazine installation restricts its movement distance in that direction, preventing it from reaching the boundary of the worktable. If the width of the profile installed on the worktable is close to the width of the profile in the X-axis direction, the spindle cannot process wider profiles. Due to this limited processing range, frequent equipment changes or secondary processing may be necessary, preventing the machining center from fully utilizing its performance, leading to reduced equipment utilization and impacting overall production efficiency.

[0003] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a tool magazine mounting structure for a machining center, effectively solving the technical defects in the existing technology where the tool magazine assembly interferes with the spindle's X-direction travel, resulting in limited processing range, low equipment utilization, and low production efficiency in profile machining centers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tool magazine mounting structure for a machining center, comprising a frame, a worktable mounted on the frame, a gantry mounted movably on the frame, and a spindle module mounted movably on the gantry. The tool magazine mounting structure includes a support plate and a tool magazine module mounted on one end of the support plate. The other end of the support plate is mounted on one side of the gantry, and the tool magazine module and the gantry are spaced apart to form a clearance area. The distance between the front surface of the spindle module and the front side of the gantry is defined as a first width, and the width of the clearance area is defined as a second width. The first width is less than the second width.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0039] 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 the accompanying drawings and embodiments.

[0040] Please refer to the following: Figures 1 to 7 The tool magazine mounting structure 20 of the machining center 100 provided in this application embodiment will now be described. The tool magazine mounting structure 20 of the machining center 100 includes: the machining center 100 and the tool magazine mounting structure 20.

[0041] The machining center 100 includes a frame 10, on which a worktable 11 is mounted for clamping profiles. A gantry 12 is movably mounted on the frame 10, and a spindle module 13 is movably mounted on the gantry 12. The gantry 12 can drive the spindle module 13 to move along the Y-axis, and the spindle module 13 can move along the X-axis of the gantry 12. The tool magazine mounting structure 20 includes a support plate 21 and a tool magazine module 22 mounted on one end of the support plate 21. The other end of the support plate 21 is mounted on one side of the gantry 12, and the tool magazine module 22 and the gantry 12 are spaced apart to form a clearance area 23. The distance from the front surface of the spindle module 13 to the front side of the gantry 12 is defined as a first width w1, and the width of the clearance area 23 is defined as a second width w2. The first width w1 is smaller than the second width w2.

[0042] Specifically, the support plate 21 is installed on one side of the gantry 12. After the tool magazine module 22 is installed on the support plate 21, it can be set with a front-to-back distance from the gantry 12 to form a clearance area 23. The second width w2 of the clearance area 23 is greater than the first width of the spindle module 13, allowing the spindle module 13 to enter the clearance area 23 for profile processing when it moves left and right in the X-axis direction. It can be seen that the installation of the tool magazine module 22 will not interfere with the movement stroke of the spindle module 13 in the X-axis direction. When the profile width is close to the width of the worktable 11, the spindle module 13 can also process the profile normally in the left and right directions without frequently changing equipment or re-clamping the profile, thereby improving the utilization rate of the machining center 100 and improving the processing production efficiency.

[0043] In some embodiments, the support plate 21 includes a horizontal plate and a vertical plate 213 mounted on the front end of the horizontal plate. The rear end of the horizontal plate is fixedly mounted on one side of the gantry 12, and the front end of the horizontal plate extends forward so that the vertical plate 213 and the gantry 12 are spaced apart. The tool magazine module 22 is fixedly mounted on the front surface of the vertical plate 213.

[0044] Specifically, the horizontal plate includes a first plate 211 and a second plate 212 integrally bent and formed. The first plate 211 and the second plate 212 form a “┏” plate structure. The lower end of the rear side of the vertical plate 213 is fixedly installed on the front end of the first plate 211 and the second plate 212. A triangular support plate A214 is welded to the left surface of the first plate 211 and the lower surface of the second plate 212. A triangular support plate B215 is welded to the upper surface of the second plate 212 and the rear surface of the vertical plate 213. A triangular support plate C216 is welded to the lower surface of the second plate 212 and the rear surface of the vertical plate 213. The support frame made of sheet metal structure can reduce weight, thereby further reducing the load-bearing weight of the gantry 12, making the power consumption of the gantry 12 displacement lower, and improving the reliability and stability of the gantry 12 displacement. At the same time, the triangular support plates A214, B215 and C216 can improve the connection strength between the first plate 211, the second plate 212 and the vertical plate 213, reduce the shaking caused by the tool magazine module 22 during tool changing operation, and thus improve the reliability of the tool changing operation.

[0045] In other embodiments, the gantry frame 12 includes a crossbeam 121 and connecting portions 122 located at both ends of the crossbeam 121 and extending downwards. First sliders 1221 are provided on the left and right sides of the bottom of the connecting portions 122. The frame 10 has two first slide rails 141 on the left and right sides of the worktable 11, with the two slide rails 141 spaced apart and extending forward and backward. The first sliders 1221 are slidably installed in the first slide rails 141. A first plate 211 is fixedly installed on the side of the connecting portion 122 and located close to the first sliders 1221. First racks 142 are installed on both the left and right sides of the frame 10, located between the two first slide rails 141 and extending forward and backward. A first actuator 123 is installed on the bottom of the rear surface of the connecting portion 122, and a first gear is installed at the output end of the first actuator 123, meshing with the first rack 142. The combination of double slide rails and double sliders can further improve the smoothness and reliability of the gantry 12 movement, and reduce the wear of the slide rails and sliders, thereby reducing the equipment maintenance cycle.

[0046] Specifically, the frame 10 has first bases 14 installed on its left and right sides, and the worktable 11 is located between the two first bases 14. The first rack 142 and the first slide rail 141 are fixedly installed on the upper surface of the first bases 14. The frame 10 has a chip removal module 143 at the bottom of the first bases 14, and a chip removal port 144 is provided on the side of the first base 14 facing the worktable 11. A protective cover is connected between the end of the first base 14 and the connecting part 122. The protective cover can prevent waste chips from splashing onto the first slide rail 141, the first slider 1221 and the first rack 142. At the same time, the discharge port provided on the side of the first base 14 facing the worktable 11 can quickly remove the waste chips from the worktable 11, reduce the accumulation of waste chips, and thus ensure that the processing can be carried out reliably.

[0047] Furthermore, the spindle module 13 includes an X-axis movable seat 131 movably mounted on the crossbeam portion 121, a Z-axis movable seat 132 movably mounted on the X-axis movable seat 131, and a spindle head 133 mounted on the Z-axis movable seat 132. The front and upper surfaces of the crossbeam 121 are provided with second slide rails 124. The X-axis moving seat 131 is equipped with a second slider 1311, which is slidably installed in the second slide rail 124. A second screw 125 is rotatably installed on the front surface of the crossbeam 121. One end of the second screw 125 is connected to a second actuator 126. A second nut seat 127 is sleeved on the second screw 125. The X-axis moving seat 131 is provided with a second fastening part 1312, which can fasten and fix the second nut seat 127. When the second actuator 126 drives the second screw 125 to rotate, the second nut seat 127 can move along the circumferential direction of the second screw 125, thereby driving the X-axis moving seat 131 to move left and right along the crossbeam 121.

[0048] The front surface of the X-axis moving seat 131 is provided with a third slider 1313, and the rear surface of the Z-axis moving seat 132 is provided with a third slide rail 1321. The third slider 1313 is slidably installed in the third slide rail 1321. The front surface of the X-axis moving seat 131 is provided with a third screw 1314. One end of the third screw 1314 is connected to a third actuator 1315, and a third nut seat 1316 is sleeved on the third screw 1314. The rear surface of the Z-axis moving seat 132 is provided with a third fastening part 1322, which can fasten and fix the third nut seat 1316. When the third actuator 1315 drives the third screw 1314 to rotate, the third nut seat 1316 can move along the axial direction of the third screw 1314, thereby driving the Z-axis moving seat 132 to move up and down relative to the X-axis moving seat 131.

[0049] It should be noted that the first, second, and third actuators are all servo motors. By using servo motors to drive the displacement of each component, the displacement accuracy can be improved.

[0050] Specifically, the spindle head 133 can be driven to cut profiles along the Y-axis by the forward and backward displacement of the gantry 12; the spindle head 133 can be driven to cut profiles along the X-axis by the forward and backward displacement of the X-axis motion seat relative to the gantry 12; and the spindle head 133 can be driven to cut profiles along the Z-axis by the up and down displacement of the Z-axis moving seat 132 relative to the X-axis moving seat 131.

[0051] In other embodiments, the frame 10 is provided with protective plates 15 at its edges, and each protective plate 15 is equipped with a movable protective door 151. This encloses the frame 10 in a space that can prevent people from entering the processing area, thus providing good protection.

[0052] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
