[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but the following embodiments are merely preferred embodiments of the present invention and are not exhaustive. Example:

[0018] like Figure 1 - Figure 8 As shown, the present invention provides a light steel milling processing equipment, including a platform 1, a multi-axis milling cutter processing part 2, a movable bracket 3 and a main structure rod 4, the platform 1 is placed on a flat ground, the multi-axis milling cutter processing part 2 is installed on one side of the middle part of the platform 1, two groups of movable brackets 3 are respectively arranged on both sides of the platform 1, and the main structure rod 4 is installed between the two groups of movable brackets 3 through a rotating shaft; A set of main support rods 5 are installed at both ends of the bottom of the main structural rod 4, and a support rod adjustment and limiting assembly 6 is installed at the middle position of the bottom of the main structural rod 4 through a rotating shaft. A side support rod 7 is installed between the ends of the two sets of main support rods 5. The two ends of the support rod adjustment and limiting assembly 6 are respectively linked to the bottom of the two sets of side support rods 7, and several sets of light steel main fixing assemblies 8 are installed inside the two sets of side support rods 7; A light steel auxiliary fixing assembly 9 for cooperating with the light steel main fixing assembly 8 is installed on the top of the main structural rod 4 .

[0019] The movable bracket 3 includes a pulley bracket body 31 and a rotating support 32. The two groups of pulley bracket bodies 31 are respectively arranged at both ends of the platform 1, and the two groups of rotating supports 32 are respectively arranged at the ends of the two groups of pulley bracket bodies 31. The bottom of the pulley bracket body 31 is provided with a universal wheel with a locking structure. The universal wheel in the locked state can keep the setting position fixed, and the universal wheel in the unlocked state can drive the pulley bracket body 31 to adjust the position. The main structural rod 4 is installed between the two groups of rotating supports 32 and is restricted by the rotating supports 32. Under the damping action of the rotating supports 32, the main structural rod 4 between the two groups of rotating supports 32 can be slowly rotated, which is convenient for adjusting the setting angle of the light steel component set on the main structural rod 4 by rotation. The rotating support 32 is restricted by adding a locking bolt to the end of the rotating support 32, thereby restricting the rotation of the main structural rod 4.

[0020] The surface of the main support rod 5 is provided with a sliding groove for the side support rod 7 to slide, and the side support rod 7 is installed in the sliding groove of the two groups of main support rods 5. The upper side of the side support rod 7 is provided with a connecting groove for the installation of the light steel main fixing component 8, and the lower side of the side support rod 7 is formed with a connecting rod that is matched with the sliding groove of the main support rod 5. When erecting the light steel structure, according to the width of the light steel structure, the setting spacing between the two groups of side support rods 7 is adjusted by pushing the side support rod 7 to make the side support rod 7 move horizontally on the surface of the main support rod 5, so that the spacing between the two groups of side support rods 7 is consistent with the width of the light steel structure.

[0021] The support rod adjustment and limiting assembly 6 includes a circular seat 61, a fixing bolt 62, a main rotation linkage rod 63 and a linkage block 64; The circular seat 61 is installed at the middle position of the bottom of the main structural rod 4 through the rotating shaft, and the fixing bolt 62 is connected to the inside of one side of the circular seat 61. The main rotating linkage rod 63 is welded to the middle part of the surface of the fixing bolt 62. Two sets of linkage blocks 64 are respectively arranged at both ends of the main rotating linkage rod 63 and connected to the bottom end of the side support rod 7. When the side support rod 7 is adjusted to the setting position on the main support rod 5 by pushing, the side support rod 7 drives the main rotating linkage rod 63 and the circular seat 61 to rotate and deflect through the linkage block 64. After the side support rod 7 reaches the position and stops, the deflection angle of the main rotating linkage rod 63 is fixed. The rotating fixing bolt 62 causes the fixing bolt 62 to form an extrusion on the main structural rod 4 through a threaded connection, and the setting position of the circular seat 61 is limited by the reaction force of the extrusion. The main rotating linkage rod 63 remains in a fixed position under the limitation of the circular seat 61, and the side support rod 7 remains fixed under the cooperation of the main rotating linkage rod 63 and the linkage block 64.

[0022] The light steel main fixing assembly 8 comprises a locking base 81, a main rod 82, a rotating portion 83 and a locking fastener 84; The locking base 81 is connected to the connecting groove on the surface of the side support rod 7, the main rod 82 is set on the surface of the locking base 81, the rotating part 83 is installed on one side of the main rod 82 through the torque knob, and the locking fastener 84 is fixed to the surface of the rotating part 83. After the setting position of the side support rod 7 is fixed, the locking base 81 is unlocked to release the locking base 81 from the side support rod 7. The locking state is achieved by adjusting the setting position of the locking base 81 on the side support rod 7 according to the length of the light steel component. After the locking base 81 reaches the setting position, the base 81 is locked again. The setting positions of the main rod 82, the rotating part 83 and the locking fastener 84 on the upper part of the locking base 81 are synchronously kept fixed. The rotating part 83 is rotated to make the rotating part 83 drive the locking fastener 84 to rotate. After the rotation, the locking fastener 84 forms a space for the light steel component to be placed in. After the light steel component is placed in, the push on the rotating part 83 is released, and the torque causes the rotating part 83 to rotate and reset. The reset rotating part 83 synchronously drives the locking fastener 84 to rotate. After the rotation, the locking fastener 84 plays a role in restricting and fixing the light steel component.

[0023] The surface of the locking fastener 84 is provided with two groups of notches symmetrically arranged with the center of the locking fastener 84 as the symmetry axis. The notches are staggered to form a fixed chamber. Several groups of locking fasteners 84 cooperate to form a fixed chamber group. The fixed chamber group formed by the locking fasteners 84 can achieve continuous fixation of the light steel component. The continuous fixation can be used to fix and reinforce the light steel component, thereby ensuring the fixation stability of the light steel component.

[0024] The notch opened on the surface of the locking fastener 84 has three different configurations, which are arc, triangle and rectangle respectively. The locking fasteners 84 of the same configuration are provided with several groups of different specifications, and there are at least four groups of locking fasteners 84 of the same configuration and specification. For light steel configurations of different shapes, a choice can be made among the three different configurations, so that the locking fastener 84 can better fit the light steel configuration, and the fixing ability of the light steel configuration is further guaranteed by improving the fit. At the same time, different light steel components can also be better fixed, thereby improving the fixation adaptability to different configurations.

[0025] The light steel auxiliary fixing assembly 9 includes a slide rail 91, a slide plate 92, a turntable seat 93, a turntable 94, a locking portion 95, a rotating linkage rod 96, a connecting sleeve 97 and a resisting member 98; The slide rail 91 is installed on the top surface of the main structural rod 4, the slide plate 92 is arranged on the surface of the slide rail 91, the turntable seat 93 is fixed on the surface of the slide plate 92, and the turntable 94 is installed on the surface of the turntable seat 93 through a rotating shaft. The locking part 95 is installed on one side of the slide plate 92 and abuts against the turntable 94. The auxiliary rotation linkage rod 96 is fixed on the surface of the turntable 94. Two sets of connecting sleeves 97 are respectively sleeved on the two ends of the auxiliary rotation linkage rod 96. The abutment 98 is fixed to the outside of the connecting sleeve 97 by bolts. After the transverse part of the light steel member is locked, the slide plate 92 is pushed to make the slide plate 92 move laterally along the slide rail 91. The slide plate 92 drives the turntable seat 93 and the turntable 94 to move synchronously. During the movement of the turntable 94, the auxiliary rotation linkage on the surface of the turntable 94 The rod 96 drives the connecting sleeve 97 and the resistance piece 98 to move synchronously. When the resistance piece 98 on one side contacts the lateral part of the light steel component, continuing to push the slide plate 92 can make the turntable 94 drive the auxiliary rotation linkage rod 96 to further move laterally. The resistance piece 98 on one side remains in contact with the lateral part of the light steel component. The auxiliary rotation linkage rod 96 rotates under the drive of the resistance piece 98 until the other group of resistance pieces 98 contacts the light steel component. When the two groups of resistance pieces 98 contact the light steel component at the same time, the locking part 95 is rotated. The rotated locking part 95 synchronously fixes the setting position of the slide plate 92 and the turntable 94. With the cooperation of the auxiliary rotation linkage rod 96 and the two groups of resistance pieces 98, the lateral part of the light steel component remains restricted and fixed.

[0026] The two groups of abutment members 98 are symmetrically arranged with the center of the rotating disk 94 as the axis of symmetry, and a lateral fixed space is formed between the two groups of abutment members 98. When the lateral part of the light steel member is arranged between the two groups of abutment members 98, the auxiliary rotating linkage rod 96 can drive the connecting sleeve 97 and the abutment member 98 to rotate by rotating the rotating disk 94. The abutment member 98 after rotation contacts the light steel member to restrict the light steel member. When in use, measure the transverse length and lateral length of the light steel member, push the main structure rod 4 so that the main structure rod 4 rotates to a horizontal state with the rotating support 32 as the axis, and after the main structure rod 4 reaches the horizontal state, the rotating support 32 is restricted by adding a locking bolt to the end of the rotating support 32, thereby restricting the rotation of the main structure rod 4, and pushing the two groups of side support rods 7 so that the spacing between the two groups of side support rods 7 is consistent with the width of the light steel member. During the width adjustment process between the side support rods 7, the side support rod 7 drives the main rotating linkage rod 63 and the circular seat 61 to rotate and deflect through the linkage block 64. After the side support rod 7 stops adjusting, the deflection angle of the rear main rotating linkage rod 63 is fixed, and the rotating fixing bolt 62 allows the fixing bolt 62 to limit the setting position of the circular seat 61 through a threaded connection. The side support rod 7 remains fixed under the cooperation of the main rotating linkage rod 63 and the linkage block 64; Select the light steel main fixing assembly 8 that matches the light steel member, install the selected light steel main fixing assembly 8 in the side support rod 7 at intervals, lock the setting position through the locking base 81 of the light steel main fixing assembly 8, rotate the rotating part 83 to make the rotating part 83 drive the locking fastener 84 to rotate, and the rotating locking fastener 84 forms a space for the light steel member to be placed in. After the light steel member is placed in, release the push on the rotating part 83, and the torque causes the rotating part 83 to rotate and reset. The reset rotating part 83 synchronously drives the locking fastener 84 to rotate, and the rotating locking fastener 84 restricts and fixes the light steel member. After the lateral part of the light steel member is locked, push the slide plate 92 to make the slide plate 92 move laterally along the slide rail 91, and the slide plate 92 The turntable seat 93 and the turntable 94 are driven to move synchronously. When the one-side abutment 98 contacts the lateral part of the light steel member, the slide plate 92 is pushed continuously to make the turntable 94 drive the auxiliary rotation linkage rod 96 to further move horizontally. The one-side abutment 98 keeps in contact with the lateral part of the light steel member. The auxiliary rotation linkage rod 96 rotates under the drive of the abutment 98 until the other group of abutment 98 contacts the light steel member. When the two groups of abutment 98 contact the light steel member at the same time, the locking part 95 is rotated. The rotating locking part 95 synchronously fixes the setting position of the slide plate 92 and the turntable 94. Under the cooperation of the auxiliary rotation linkage rod 96 and the two groups of abutment 98, the lateral part of the light steel member remains restricted and fixed. After completing the milling of the light steel component on one side, release the locking bolt added at the end of the rotating support 32, push the main structure rod 4 to rotate, and the rotating main structure rod 4 drives the light steel component to flip through the cooperation of the main support rod 5, the support rod adjustment limit assembly 6, the side support rod 7 and the light steel main fixing assembly 8, so as to facilitate the processing of the back of the light steel component, and then release the locking state of the pulley bracket body 31, adjust the lateral position of the pulley bracket body 31 to form a new processing working surface.

During the width adjustment process between the side support rods (7), the side support rods (7) drive the main rotating linkage rod (63) and the circular seat (61) to rotate and deflect through the linkage block (64). After the side support rods (7) stop adjusting, the deflection angle of the rear main rotating linkage rod (63) is fixed, and the fixing bolt (62) is rotated so that the fixing bolt (62) limits the setting position of the circular seat (61) by means of threaded connection. The side support rods (7) are kept fixed under the cooperation of the main rotating linkage rod (63) and the linkage block (64); Step S3, selecting a light steel main fixing assembly (8) matching the light steel component, installing the selected light steel main fixing assembly (8) in a spaced manner in the side support rod (7), locking the setting position by means of a locking base (81) of the light steel main fixing assembly (8), rotating the rotating part (83) so that the rotating part (83) drives the locking fastener (84) to rotate, and the rotating locking fastener (84) forms a space for the light steel component to be placed, and after the light steel component is placed, releasing the push on the rotating part (83), and the torque causes the rotating part (83) to rotate and reset, and the reset rotating part (83) synchronously drives the locking fastener (84) to rotate, and the rotating locking fastener (84) restricts and fixes the light steel component; Step S4, after the lateral portion of the light steel member is locked, the slide plate (92) is pushed to make the slide plate (92) move laterally along the slide rail (91), and the slide plate (92) drives the turntable seat (93) and the turntable (94) to move synchronously, and when the one side contact member (98) contacts the lateral portion of the light steel member, the slide plate (92) is continuously pushed to make the turntable (94) drive the auxiliary rotation linkage rod (96) to further move laterally, and the one side contact member (98) keeps contacting the lateral portion of the light steel member, and the auxiliary rotation linkage rod (96) rotates under the drive of the contact member (98) until the other group of contact members (98) contacts the light steel member; Step S5, when the two groups of abutment members (98) are in contact with the light steel member at the same time, the locking portion (95) is rotated, and the rotated locking portion (95) synchronously fixes the setting positions of the slide plate (92) and the turntable (94), and under the cooperation of the auxiliary rotation linkage rod (96) and the two groups of abutment members (98), the lateral portion of the light steel member remains restricted and fixed; Step S6, after the milling process of the light steel component on one side is completed, the locking bolt added to the end of the rotating support (32) is released, and the main structure rod (4) is driven to rotate. The rotating main structure rod (4) drives the light steel component to flip through the cooperation of the main support rod (5), the support rod adjustment limit assembly (6), the side support rod (7) and the light steel main fixing assembly (8), so as to facilitate the processing of the back side of the light steel component; Step S7, by releasing the locked state of the pulley bracket body (31), the lateral position of the pulley bracket body (31) is adjusted to form a new processing surface.
