Description

Technical Field

[0001] This utility model relates to the field of drilling and positioning technology, specifically a drilling and positioning device for metal castings. Background Technology

[0002] Drilling holes in metal castings facilitates assembly and can also relieve stress generated during processing or welding. Drilling holes in the castings allows stress to be released in a concentrated manner, preventing deformation.

[0003] However, there are certain drawbacks in the existing casting drilling process. As the drill bit used in the drilling equipment rotates at high speed and penetrates into the casting, the drill bit may vibrate at the moment of pressure due to human interference with the drilling device or excessive instantaneous mechanical extrusion. In severe cases, this may cause irregularities in the inner wall of the casting.

[0004] In view of this, a drilling and positioning device for metal castings was designed to solve the above problems. Utility Model Content

Limiting blocks are movably installed in the sliding grooves, and limiting rods are fixedly installed on the limiting blocks. Springs are provided on the outside of the limiting rods, and the springs are adapted to bear pressure on the base and the limiting blocks. A chuck is fixedly installed on the top of the limiting blocks. The drill rod calibration component includes a load-bearing arm movably installed on the chuck. A clamping seat is movably installed at the other end of the load-bearing arm. A protective sleeve is fixedly installed inside the clamping seat. Four symmetrically distributed inner pads are provided inside the protective sleeve, and leaf springs connect the inner pads and the protective sleeve.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1.

[0023] 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 specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a drilling and positioning device for metal castings.

[0026] Example 1:

[0027] Combination Figures 1 to 4 As shown, the present invention provides a drilling and positioning device for metal castings, including a drill bit stabilization mechanism 100, a magnetic suction component 200 mounted on the drill bit stabilization mechanism 100, and a drill rod calibration component 300 mounted on the drill bit stabilization mechanism 100. The drill bit stabilization mechanism 100, together with the drill rod calibration component 300, is used to provide stabilization and protection for the drill bit of the drilling machine, and the magnetic suction component 200 is used to adjust the hole position of the drill bit stabilization mechanism 100.

[0028] The drill bit stabilization mechanism 100 includes a base 110, with four sliding grooves 1101 inside the base 110. A limiting block 120 is movably installed in the sliding groove 1101. A limiting rod 140 is fixedly installed on the limiting block 120. A spring 150 is provided on the outside of the limiting rod 140, and the spring 150 is adapted to bear pressure on the base 110 and the limiting block 120. A chuck 130 is fixedly installed on the top of the limiting block 120.

[0029] The magnetic assembly 200 includes a base 210 mounted on the outside of two studs 1102, a positioning member 230 movably mounted inside the base 210, a coil 240 wound around the positioning member 230, and a housing 220 mounted on the outside of the positioning member 230. The base 210 is welded together from two horizontal plates and a cylindrical housing, and the bottom end of the positioning member 230 is movably mounted in a groove inside the cylindrical housing.

[0030] The drill pipe calibration assembly 300 includes a load-bearing arm 310 movably mounted on the chuck 130, a clamping seat 3201 movably mounted on the other end of the load-bearing arm 310, a protective sleeve 320 fixedly mounted inside the clamping seat 3201, four symmetrically distributed inner pads 340 provided inside the protective sleeve 320, and a leaf spring 330 connecting the inner pads 340 and the protective sleeve 320.

[0031] The inner pad 340 has an overall L-shaped structure, and a sliding column 3401 is fixedly installed inside the inner pad 340. The sheath 320 has four sliding grooves, and the sliding column 3401 is adapted to pass through the sliding grooves.

[0032] When in use, the coil 240 is energized beforehand until the positioning member 230 magnetically fixes the upper surface of the casting. Then, the drill bit stabilizing mechanism 100 and the base 210 are controlled to rotate around the positioning member 230 as the axis until the drill bit stabilizing mechanism 100 stops at the selected position of the casting. Then, the drill bit of the drilling machine is inserted along the four inner pads 340 until the drill bit passes through the four limit pressure blocks 120 and continues to squeeze into the interior of the casting.

[0033] As the drill bit rotates at high speed, the continuously descending drill bit is centrally constrained by four evenly distributed inner pads 340 and four limiting blocks 120, thereby ensuring the stability of the drill bit during its penetration into the casting and preventing the internal holes of the casting from becoming deformed due to drill bit vibration.

[0034] Example 3:

[0035] Combination Figure 3 and Figure 4 As shown, in the above embodiment, the base 110 has a cross-shaped structure, and a through hole is provided in the plate end of the outer end of the base 110. The limiting rod 140 is adapted to fit one end of the limiting pressure block 120 and passes through the through hole.

[0036] Four studs 1102 are fixedly installed at the bottom of the load-bearing arm 310, and nuts are installed on the outside of the studs 1102.

[0037] Preferably, the limiting pressure block 120 has an overall U-shaped structure, and the length of the bottom plate segment of the limiting pressure block 120 is twice the length of its top plate segment. The lower surface of the bottom plate segment of the limiting pressure block 120 has a rough structure to enhance the stability of the casting after attachment.

[0038] The working principle and usage process of this utility model are as follows: The device is placed on the upper surface of the casting in advance. At this time, the bottom of the positioning part 230 is adapted to fit the upper surface of the casting. Then, the positioning part 230 is energized and causes the positioning part 230 to generate magnetic force to attract and fix the casting.

[0039] Next, the drill bit of the drilling machine is inserted into the gaps inside the four inner pads 340 until the drill rod is fitted and clamped by the four inner pads 340 and thus stabilized and constrained. As the drill bit continues to descend and enters the inner side of the four limiting blocks 120, the vertically descending drill bit will quickly drill holes in the casting. When the drilling machine is running, the high-speed rotating drill bit achieves stable drilling under the dual constraint of the four inner pads 340 and the four limiting blocks 120, avoiding the problem of irregular hole shape caused by the drill bit pressure center deviating or shaking during the drilling of the casting.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
