Description

Technical Field

[0001] The present invention belongs to the technical field of processing devices for miter saw components, and particularly relates to a processing device for a miter saw base. Background Art

[0002] The Chinese invention patent with the authorization announcement number CN 106984860 B discloses a miter saw;

[0003] The Chinese invention patent with the authorization announcement number CN 111085873 B discloses a miter saw;

[0004] The above two patents describe a miter saw with a telescopic headstock. Compared with an ordinary miter saw, such as the miter saw disclosed in the Chinese invention patent with the authorization announcement number CN103586532B, this miter saw has a larger cutting range and enhanced practicability.

[0005] Regardless of which type of miter saw, its base is generally formed by aluminum die-casting. The die-casting process requires draft angles on both the upper and lower surfaces. The shape of the base 01 of the telescopic miter saw is as shown in Figure 1 and Figure 2 One end is disc-shaped and the other end extends narrowly outward. An ordinary miter saw does not have this extended section. It needs to machine planes in three directions, and there are also some mounting holes or some mounting screw holes to be machined around the three planes. For ease of description, with reference to the attached drawing labels, the planes to be machined are represented by the letter m, which are the reference plane m1 located at the upper part, the headstock mounting plane m2, and the bottom plane m3 respectively. During machining, it is necessary to first machine the reference plane m1, and then use this reference plane for positioning to machine the remaining surfaces and holes. Therefore, during machining, it is necessary to perform multiple clamping and flipping in at least two directions. Moreover, since the external dimensions in the length direction of the base generally exceed 500 mm, it is relatively difficult to fabricate a relatively simple flipping fixture to complete the machining in a machining center at one time.

[0006] Currently, the processing method for the base is to complete it through multiple turnovers and repeated clamping between different processes, resulting in low processing efficiency and high labor intensity. Summary of the Invention

The shape and operation mode of the positioning rotating frame provide multiple working surfaces, which is convenient for improving processing efficiency, and the space in the middle provides the mechanism for turning over and unloading for arrangement.

[0011] Preferably, each clamping mechanism arranges the clamping position in a symmetrical manner on the same plane, and the clamping mechanism includes an elastic inner ring clamping block having an opening on one side of the clamping base disc and directly contacts and clamps the base side on the inner ring, and a rigid outer ring rotating frame for installing the elastic clamping block.

Moreover, due to the establishment of multiple processing surfaces, the processing efficiency is improved, the labor intensity is reduced, and the product no longer needs to be transferred. The entire device occupies a small space. It can easily obtain reliable clamping by using the draft angle for side clamping, without interfering with the processing position. The original multiple repeated positioning is reduced to only one positioning for switching the reference surface. Therefore, the entire processing rate and processing accuracy are greatly improved, basically achieving the effect of a machining center. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0036] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings:

[0037] Embodiment 1

[0038] The present disclosure provides a processing device for a miter saw base. Figure 3 The figure shows a schematic diagram of the processing device during operation, including a device mounting table 10, a processing device 20 fixed on the tabletop of the device mounting table 10, a feeding conveyor belt 30 located in front of the processing device 20, and a discharging conveyor belt 40 located below the processing device 20.

[0039] Figure 7 The figure shows the processing device 20, including a device main body 21 with a driving, clamping, and control system, a positioning turntable 22 with a central axis a1 at one end and a rotating ring a2 at the other end, and the central axis a1 is positioned and connected through clamping in the device main body 21, and the rotating ring a2 is positioned and connected through nesting. A milling processing assembly 23 is located above the device main body 21 and is detachably and fixedly connected to the device main body 21. A forward drilling and tapping assembly 24 is located behind the processing device 20, is axially parallel to the central axis a1, can be translated along this axis, and the distance from this axis can be changed. A lateral drilling and tapping assembly 25 is located behind the processing device 20 and is detachably and fixedly connected to the two sides of the device main body 21. A magnetic suction seat 26 is fixedly connected to the rotating ring a2 in a closely rotatable manner; the magnetic suction seat 26 provides a supporting effect for the rotating ring a2 and provides magnetic suction fixation when the positioning turntable 22 rotates to a preset position.

[0040] Figure 6 The figure shows the positioning turntable 22, which is located between the central axis a1 and the rotating ring a2. The positioning turntable 22 includes a turntable main body 223 with a plate surface on one side of the central axis a1 and a frame shape for the rest, and a square cross-section. Clamping mechanisms 221 for clamping the base 01 are respectively arranged on the four faces of the square. An active push table 222 is arranged in the turntable main body 223 to push the base 01 upward and push the base downward to complete unloading after all processing is completed. Each clamping mechanism 221 can independently flip the surface and lock, and the device main body 21 drives the positioning turntable 22 to rotate 90 degrees each time to switch the processing surface, thereby completing the processing of different processes. The upward pushing of the base in the active push table 222 is to assist in repositioning with the reference plane m1 as the reference after the processing of the reference plane m1 is completed and the surface is changed, so as to obtain the processing of the remaining parts. Figure 8 and Figure 9 show the installation position of the active push table 222 and are partially cut open for easy observation of internal details.

[0041] Figure 5The schematic diagram of the clamping mechanism 221 after clamping the base 01 is shown. In view of the shape of the base 01, each clamping mechanism 221 sets the clamping position in a symmetrical manner on the same plane to improve space utilization. The clamping mechanism 221 includes an elastic inner ring clamping block 21a with an opening located on one side of the clamping base 01 disc, which is directly in contact with and clamped by the inner ring, and is used to install the rigid outer ring rotating frame 21b of the elastic inner ring clamping block 21a; the side of the elastic inner ring clamping block 21a has the same draft angle as the base 01, and the role of its opening is to leave space for clamping and also for processing the head mounting surface m2; the material of the elastic inner ring clamping block 21a is preferably nylon plate;

[0042] The elastic inner ring clamp block 21a and the rigid outer ring rotating frame 21b are both frame structures. The shape of the rigid outer ring rotating frame 21b is as follows: Figure 10 As shown, there is also an opening on one side of the disc of the clamping base 01. The function of the opening is to leave space for the processing of the head mounting surface m2. The elastic inner ring clamp 21a is fixed by bolts a11 on the middle plane of the frame, and the two arc sections on both sides are provided with pneumatic pressing pieces a12. When clamping is required, the pressing pieces a12 extend outward to push the arc sections of the elastic inner ring clamp 21a to move inward, that is, the elastic inner ring clamp 21a is subjected to force at the opening to clamp the base 01; in addition, a short shaft a13 is respectively provided at the center of the two ends of the rigid outer ring rotating frame 21b, one of the short shafts a13 can be connected to the air nozzle, and an air channel is provided between the short shaft a13 and all the pressing pieces a12, so as to obtain the power source of the pressing piece a12, and a positioning hole a14 is provided next to each short shaft a13, and the positioning hole a14 is used for the external pin shaft to enter so that the clamping mechanism 221 is fixed.

[0043] Figure 11 The rotating frame body 223 is shown. It can be seen that each frame beam at one end of the rotating frame body 223 is disconnected, and there is also a notch on the plate surface at the other end. The purpose is to provide processing space as mentioned above. A swivel a2 is fixedly connected to one end of the rotating frame body 223 by bolts, and a gear ring a3 is fixedly connected to the other end by bolts. The gear ring a3 is connected to the discharge conveyor belt 40 through the transmission cooperation of the gear and the synchronous belt to provide power for the discharge conveyor belt 40. The advantage of such a setting is that the action rhythm of the two is consistent. In addition, the swivel a2 and the gear ring a3 also stabilize the frame form of the rotating frame body 223 with a notch; each frame beam and plate surface on the end face of the rotating frame body 223 is provided with a first hole k1 and a second hole k2, wherein the first hole k1 is located at the center of the internal space. After the first holes k1 at both ends cooperate with the short shafts a13 at both ends of the rigid outer ring rotating frame 21b, a rotatable connection is completed. The second hole k2 corresponds to the position of the positioning hole a14, and timely positioning is performed by setting a pneumatic positioning pin a15 externally; Figure 6The schematic diagram shown is after the clamping mechanisms 221 are installed on the four sides of the rotating frame body 223 respectively. In order to enable each clamping mechanism 221 to be turned over individually, a turning motor a16 connected to one of the short shafts a13 is arranged at one end of the rotating frame body 223.

[0044] The central axis a1 has a cylindrical extension toward the inside of the rotating frame body 223, such as Figure 9 , Figure 11 As shown, the movable push platform 222 includes a rack rail 22a which is tightly and rotatably sleeved on the cylinder at one end and fixed at the other end by setting a track support seat 22b1, and a push platform box 22b with a rectangular box structure; both ends of the box are provided with a passage hole 22c with the same cross section as the rack rail 22a, and the center line of the passage hole 22c coincides with the axis of the rack rail 22a; the cross section of the rack rail 22a is from Figure 11 It can be seen that the bottom is an arc and the top is a rectangle, and the teeth are on the upper surface of the rectangle. The arc of the cross-sectional shape is convenient for sliding, and the rectangle ensures that the rectangular box is stable when moving. The gear drive motor 22d is fixedly arranged on the outward end surface of the rectangular box to mesh with the teeth on the upper surface of the rack slide 22a, so that the gear drive motor 22d can move along the direction of the rack slide 22a when it is running;

[0045] See also Figure 12 A group of piston through holes 22e are diagonally provided on the upward and downward surfaces of the push platform box 22b. The positions of the piston through holes 22e on the downward surface and the piston through holes 22e on the upward surface are staggered, that is, they are downward in the direction of the draft angle, so that the processed base can fall onto the discharge conveyor belt 40. Generally speaking, the base can fall by its own weight. The movable push platform 222 also includes a first piston assembly 22f for pushing upward and a second piston assembly 22g for pushing downward, which are arranged in the push platform box 22b.

[0046] Overall workflow:

[0047] Refer to all attached Figure 1-13, for ease of description, the feeding end of the positioning turntable 22 is called the feeding working surface, the corresponding side is the first drilling and tapping working surface, the upward-facing side is the milling working surface, the two end faces are the second drilling and tapping working surface and the third drilling and tapping working surface respectively, and the downward-facing side is the unloading working surface. First, the operator places the two bases 01 to be processed onto the clamping mechanism 221 from the feeding working surface. The base 01 is higher than the clamping mechanism 221 at this location to provide space for milling. After the clamping mechanism 221 is activated to clamp, that is, the pressing member a12 pushes the elastic inner ring clamping block 21a. After the device main body 21 is activated, it rotates 90 degrees, the magnetic suction seat 26 is locked, and the rigid outer ring turntable 21b is locked. The two bases 01 are transferred to the milling working surface, and the operator then continues to feed. The milling of the base 01 is extensive, and generally a disk milling cutter with multiple cutting heads is used. Due to the sufficient working surface, in order to improve efficiency, in this embodiment, two milling power heads are used for processing together. After the milling process is completed, the gear drive motor 22d is activated to move the push table box body 22b out of the positioning turntable 22 to provide space for turning over. The locking of the rigid outer ring turntable 21b is released, the turning-over motor a16 is activated to turn over, the gear drive motor 22d is activated to move the push table box body 22b back, the pressing member a12 is released, and the two disk milling cutters respectively move into position and move downward to the upper side of one of the disks of the base 01. The first piston assembly 22f is activated to push the two bases 01 upward until they are in contact with the disk milling cutter, and then the pressing member a12 is locked, and the rigid outer ring turntable 21b is locked. This positioning method is equivalent to positioning using the machining accuracy of the disk milling cutter, with higher accuracy. Then, milling and milling of the side m2 are continued synchronously. After completion, the above actions are repeated, rotating to the first drilling and tapping working surface for processing, and finally rotating to the unloading working surface for unloading.

[0048] It should be noted that in this processing method, the specific type of processing power head and how the power head is installed and arranged are not described in detail in this embodiment. This is because for those skilled in the art, the arrangement of the power head can be easily achieved under the condition of leaving a working surface.

[0049] The specific embodiments described in the text are only examples to illustrate the spirit of the present invention. Those skilled in the technical field to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
