Description

Technical Field

[0001] This utility model relates to the field of metal bracket processing technology, and more specifically, it relates to a positioning and drilling fixture for metal bracket processing. Background Technology

[0002] In the industrial field, metal brackets are widely used in various large-scale mechanical equipment and complex engineering structures. They not only have excellent load-bearing capacity and durability, but also maintain stable performance under various harsh environmental conditions. They can be flexibly adjusted and optimized according to different usage scenarios and needs, providing reliable support and guarantee for industrial production and engineering construction. They are an indispensable and important part of modern industry. During the processing of metal brackets, drilling tools are needed to drill holes in the surface of the brackets to facilitate subsequent assembly.

[0003] However, existing drilling tools can only position the two sides of the metal bracket when in use. This positioning method is relatively simple. During the drilling process, the profile is prone to displacement, which leads to deviation in the drilling position.

[0004] Furthermore, the existing drilling tools have a relatively complicated installation method for the drill bits, most of which are fixed with screws. This means that when the drill bits need to be disassembled and replaced later, tools are still required, which affects the replacement efficiency. Utility Model Content

[0031] In this embodiment, the outer walls of the mounting post 12 and the mounting sleeve 11 are respectively provided with through holes 13. A pin 14 is movably provided inside the through hole 13. The outer wall of the mounting sleeve 11 is provided with external threads. The outer end of the pin 14 is provided with a limiting nut 15.

The slider 17 is located inside the sliding groove 16.

[0032] More specifically, the user can control the hydraulic cylinder 3 to make the lifting plate 4 move the drill bit 6 downward to contact the profile of the metal bracket to achieve the drilling effect. Before the drill bit 6 contacts the profile, the pressure plate 8 will first abut against the upper end of the profile to provide a downward force to the profile, thereby improving its positioning effect. When it is necessary to disassemble the drill bit 6, the limit nut 15 can be turned to disengage it from the pin 14. At this time, the pin 14 can be removed from the inside of the through hole 13 to achieve the effect of disassembling the drill bit 6 for easy replacement.

[0033] Please see Figure 1 , Figure 2 and Figure 5 As an embodiment for moving the profile used to make the metal bracket: a T-slot 18 is provided on the upper end surface of the base 1 at the middle position, a T-block 19 is slidably provided inside the T-slot 18, a placement plate 20 is fixedly provided on the upper end surface of the T-block 19, a lead screw 21 is rotatably provided inside the T-slot 18, the lead screw 21 is threadedly connected to the T-block 19, a second motor 22 is fixedly provided at one end of the lead screw 21 on the outer wall of the base 1, and a groove is provided at the middle position of the placement plate 20.

[0034] Specifically, the user can place the metal bracket profile on the upper end of the placement plate 20, and then turn the handwheel 26 to make the threaded column 24 drive the clamping block 25 to move, so that the clamping block 25 clamps and fixes the profile on the upper end of the placement plate 20. When drilling, the second motor 22 can be controlled to make the lead screw 21 drive the placement plate 20 and the profile to move, so as to perform drilling operations at different positions.

The threaded posts 24 are threadedly connected to the upright plates 23. One end of the threaded posts 24 passes through the upright plates 23 and is provided with a clamping block 25, and the other end is provided with a handwheel 26.

[0036] Specifically, the user can use the handwheel 26 to clamp and fix the two ends of the profile with the clamping block 25, which makes it convenient to adjust the drilling position later.

[0037] In summary, when using the overall equipment: the user can place the metal bracket profile to be processed on the upper end of the placement plate 20, and then turn the handwheel 26 to move the threaded column 24 to drive the clamping block 25 to move, so that the clamping block 25 clamps and fixes the profile at the upper end of the placement plate 20. Then, control the hydraulic cylinder 3 to move the lifting plate 4 to move the drill bit 6 downward to contact the metal bracket profile to achieve the drilling effect. Before the drill bit 6 contacts the profile, the pressure plate 8 will first abut against the upper end of the profile to provide downward force to the profile, thereby improving its positioning effect. During the drilling process, the second motor 22 can also be controlled to move the lead screw 21 to drive the placement plate 20 and the profile to perform drilling operations at different positions, increasing practicality. When it is necessary to disassemble the drill bit 6, the limit nut 15 can be turned to disengage it from the pin 14. At this time, the pin 14 can be removed from the inside of the insertion hole 13 to achieve the effect of disassembling the drill bit 6 for easy replacement.
