DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides a grinding fixture for the surface of an aluminum alloy box, comprising a workbench 1, a fixing frame 2, a grinding assembly 3 and a mounting plate 4. The fixing frame 2 and the mounting plate 4 are fixedly connected to the upper end surface of the workbench 1 at intervals, the grinding assembly 3 is fixedly connected to the top of the side adjacent to the fixing frame 2 and the mounting plate 4, a fixing assembly 6 is arranged on the side adjacent to the fixing frame 2 and the mounting plate 4, a rotation adjustment portion 8 is arranged on the side of the fixing frame 2 away from the mounting plate 4, one end of the fixing assembly 6 is fixedly connected to the rotation adjustment portion 8, an adjustment component 7 is arranged on the front end surface of the fixing frame 2, and a connecting rod 5 is fixedly connected to the side adjacent to the mounting plate 4 and the fixing frame 2;

[0026] The fixing assembly 6 includes a rotating shaft 61 and a mounting rod 62. The mounting rod 62 is rotatably connected to one end of the rotating shaft 61. Four groups of clamping assemblies 63 are arranged on the outside of the mounting rod 62 in parallel with the mounting rod 62. Two groups of telescopic support columns 64 are fixedly connected to one side of the clamping assembly 63 adjacent to the mounting rod 62. A slip ring 65 is slidably connected to the outside of the mounting rod 62. The slip ring 65 is fixedly connected to the outside of the telescopic support columns 64 with the same number as the clamping assembly 63.

[0027] The connecting rod 5 includes a sleeve 51 and a threaded rod 52 . One end of the threaded rod 52 is fixedly connected to the inside of the sleeve 51 by threads. The sleeve 51 is sleeved on one end of the mounting rod 62 away from the rotating shaft 61 .

[0028] Specifically, the aluminum alloy box is arranged outside the fixing component 6, wherein the four groups of clamping components 63 support the four groups of inner walls of the aluminum alloy box. By rotating the rotating adjustment part 8, the aluminum alloy box is adjusted to face different sides upward, thereby effectively improving the grinding efficiency.

[0029] It should be noted that the grinding assembly 3 is a conventional horizontally adjustable grinding assembly, and its main components include a hydraulic cylinder, a motor, a grinding head, a screw and a fixed seat. There are two groups of motors, one group of motors is used to drive the grinding head, and the other group drives the screw. The motor for installing the grinding head is installed at the output end of the hydraulic cylinder. The hydraulic cylinder is used to adjust the height of the motor. The hydraulic cylinder is fixed under the fixed seat, and the fixed seat is penetrated by the screw. Another group of motors is used to drive the screw to rotate, thereby adjusting the position of the fixed seat.

[0030] See also Figure 5 The clamping assembly 63 includes a fixing rod 631, an elastic strip 634 is slidably connected inside the fixing rod 631, one end of the elastic strip 634 is fixedly connected to a fixing block 632, a clamping block 1 633 is fixedly connected to the side of the upper end surface of the fixing block 632 facing away from the fixing rod 631, and a clamping block 2 635 is fixedly connected to the side of the upper end surface of the fixing rod 631 facing away from the fixing block 632.

[0031] Furthermore, a spring is disposed inside the fixing rod 631 , one end of the spring is fixedly connected to one end of the elastic strip 634 away from the fixing block 632 , and the other end of the spring is fixedly connected to the inner wall of the fixing rod 631 .

[0032] Specifically, when the clamping assembly 63 supports the aluminum alloy box, the spring inside the telescopic support column 64 will be in a compressed state, and the aluminum alloy box will be put on the outside of the fixing assembly 6, one end of the aluminum alloy box will be against the four sets of clamping blocks 635, and then the elastic strip 634 will be pulled out to make the clamping block 633 clamped on the other end of the aluminum alloy box, completing the pre-fixation of the aluminum alloy box. When fixed, no objects will extend from the two ends of the aluminum alloy box, thereby facilitating the comprehensive polishing of the aluminum alloy box.

[0033] It should be noted that the elastic strip 634 is made of elastic material, and the card block 1 633 can be separated from the aluminum alloy box by pressing the card block 1 633 .

[0034] See also Figure 6 The telescopic support column 64 includes a column and a pipe sleeve. The column is slidably connected to the inside of the pipe sleeve. A spring is provided inside the pipe sleeve. One end of the spring is fixedly connected to the bottom of the inner cavity of the pipe sleeve, and the other end is fixedly connected to one end of the column sliding inside the pipe sleeve.

[0035] Furthermore, one end of the four groups of telescopic support columns 64 outside the slip ring 65 away from the slip ring 65 is fixedly connected to the fixing blocks 632 on the four groups of clamping components 63 respectively.

[0036] Specifically, by adjusting the position of the sleeve 51 through the thread, the sleeve 51 is pressed against the slip ring 65, which can ensure that when the aluminum alloy box is being polished, the spring inside the clamping assembly 63 will not be deformed due to horizontal friction, thereby causing the aluminum alloy box to deviate and affecting the polishing effect.

[0037] In addition, the spring inside the telescopic support column 64 can also prevent the grinding head from exerting too much pressure on the aluminum alloy box when grinding, thereby preventing the problem of over-grinding.

[0038] like Figure 7 As shown, a sliding connection groove 21 is opened inside the fixed frame 2, and the adjusting component 7 includes a pull rod 71 and a limit block 73. One end of the pull rod 71 is fixedly connected to the upper end surface of the limit block 73. A spring 72 is provided outside the pull rod 71. One end of the spring 72 is fixedly connected to the top of the sliding connection groove 21, and the other end is fixedly connected to the limit block 73. The limit block 73 is slidably connected inside the sliding connection groove 21.

[0039] like Figure 8 As shown, the rotation adjustment part 8 includes a turntable 81 and a main shaft 83. The front end surface of the turntable 81 is fixedly connected to the main shaft 83, and the end of the main shaft 83 facing away from the turntable 81 is fixedly connected to a rotating handle 84. Four groups of positioning grooves 82 are symmetrically opened on the outside of the turntable 81, and the side of the turntable 81 facing away from the main shaft 83 is fixedly connected to the end of the rotating shaft 61 facing away from the mounting rod 62.

[0040] Furthermore, the turntable 81 is rotatably connected inside the fixing frame 2 , and the sliding connection groove 21 is arranged outside the rotation position of the turntable 81 , and the size of the limit block 73 is adapted to the positioning groove 82 .

[0041] Specifically, the limit block 73 will be embedded in the positioning groove 82 under the action of the spring 72, so that the positioning groove 82 cannot rotate. By pulling the pull rod 71 outward, the handle 84 can be rotated to adjust the polished surface of the aluminum alloy box, which is easy to operate and has high reliability.

[0042] Working principle: Rotate the sleeve 51 to separate it from the mounting rod 62, then rotate the mounting rod 62 to put the aluminum alloy box on the outside of the fixing component 6, one end of the aluminum alloy box is against the four sets of clamping blocks 2 635, then pull out the elastic strip 634 to make the clamping block 1 633 clamped on the other end of the aluminum alloy box, reset the mounting rod 62, and readjust the position of the sleeve 51 so that the sleeve 51 is against the slip ring 65, start the grinding component 3 to grind the first surface of the aluminum alloy box, pull out the pull rod 71, rotate the aluminum alloy box 90° by turning the handle 84, then release the pull rod 71, and grind the second surface of the aluminum alloy box until all surfaces are polished.
