Description

Technical Field

[0001] This utility model relates to the technical field of drilling machine fixtures, specifically to a drilling jig for a pressure relief valve cover of an empty or loaded vehicle. Background Technology

[0002] A pressure relief valve is a safety device installed on a pressure vessel or pipeline system. Its main function is to control and limit the pressure inside the system, ensuring that the system operates within the installed pressure range.

[0003] The pressure relief valve cover has multiple holes, which need to be drilled using a drilling machine. During drilling, the pressure relief valve cover needs to be clamped and fixed to ensure the accuracy of the drilling. Since the holes on the pressure relief valve cover are different, the pressure relief valve cover needs to be clamped and positioned at different angles during drilling. The most difficult angle to clamp and position is when the pressure relief valve cover needs to be erected before clamping and positioning. Currently, clamping and positioning the pressure relief valve cover when it is erected often requires multiple clamps and bolts to achieve the clamping purpose, but the clamping effect is not good, displacement is easy to occur, and the clamping process is also relatively complicated. Utility Model Content

[0004] To address the aforementioned problem of difficulty in quickly and stably clamping the pressure relief valve cover when it is erected, this utility model proposes a drilling jig for the pressure relief valve cover of empty and loaded vehicles. The jig includes a base plate with a vertical plate perpendicular to it. The valve cover body is connected to the vertical plate via quick-release bolts, and the bottom surface of the valve cover body is flush against the vertical plate. A drilling jig mechanism is also provided on the base plate, with a drill sleeve vertically mounted on it, corresponding to the hole to be machined on the valve cover body.

[0005] A further feature of this invention is that the quick-change bolt includes a bolt rod that passes through the mounting hole of the valve cover body and the upright plate. One end of the bolt rod is threaded and connected to a nut. The other end is provided with two symmetrically arranged slots. The invention also includes a retaining plate with slots that are compatible with the slots. The retaining plate engages with the slots through the slots and abuts against the valve cover body.

[0006] A further feature of this invention is that the drilling jig mechanism includes a support base, the support base is disposed on the base plate, the top end of the support base is connected to a drilling template, and the drilling sleeve is disposed on the drilling template.

[0007] A further feature of this invention is that a positioning block is provided on one side of the support base, and one end of the valve cover body abuts against the positioning block.

[0008] The beneficial effects of this utility model are as follows:

[0009] By using the upright plate and quick-change bolts, the valve cover body can be quickly fixed in place, thereby enabling the drilling of holes on the valve cover body. Attached Figure Description

[0015] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0016] refer to Figure 1 , 3 This utility model proposes a drilling mold for a pressure relief valve cover of an empty or loaded vehicle, including a base plate 1, which is used to fix the base plate 1 on the drilling platform. A vertical plate 2 is bolted to the upper surface of the base plate 1. The vertical plate 2 is set perpendicular to the base plate 1. The vertical plate 2 also has three through holes corresponding to the three mounting holes on the valve cover body 3. The three mounting holes of the valve cover body 3 are aligned with the three through holes on the valve cover body 3, and the valve cover body 3 can be fixedly installed on the vertical plate 2 by using quick-change bolts 4. During installation, the bottom surface of the valve cover body 3 is tightly attached to the surface of the vertical plate 2 so that the valve cover body 3 remains upright.

[0017] The base plate 1 is also provided with a drilling jig mechanism 5, on which a drill sleeve 6 is installed. The drill sleeve 6 is set on the hole to be processed on the valve cover body 3, so as to cooperate with the drill bit to realize the purpose of drilling the hole to be processed on the valve cover body 3.

[0018] refer to Figure 4The quick-change bolt 4 includes a bolt shank 41 and a retaining plate 42. The bolt shank 41 passes through a mounting hole and a through hole. One end of the bolt shank 41 has an external thread, and the other end has two symmetrically arranged retaining grooves 411. The end with the external thread is located on the side of the upright plate 2 away from the valve cover body 3, and the end with the retaining grooves 411 is located on the side of the valve cover body 3 away from the upright plate 2. A nut is threadedly connected to the threaded end of the bolt shank 41. The retaining plate 42 has a locking slot 421 that matches the retaining grooves 411, making the retaining plate 42 U-shaped. The retaining plate 42 is engaged in the two retaining grooves 411, and the retaining plate 42 abuts against the valve cover. Then, by tightening the nut, the valve cover body 3 is tightened and fixed.

[0019] The drilling mechanism 5 is located on the side of the valve cover body 3 away from the vertical plate 2. The drilling mechanism 5 includes a support base 51, which is connected to the base plate 1 by bolts and is set perpendicular to the base plate 1. The top of the support base 51 is provided with an installation groove, and a drilling template 52 is installed in the installation groove. The lower surface of the drilling template 52 is covered with a protruding installation part that is integrated with the installation groove. The drilling template is positioned and installed by the cooperation of the installation part and the installation groove, and is fixed by bolts.

[0020] The drill template 52 has a machining hole corresponding to the hole to be machined on the valve cover body 3. A drill template sleeve is embedded in the machining hole to cooperate with the drill bit.

[0021] refer to Figure 2 A positioning block 53 is bolted to one side of the support base 51. One end of the valve cover body 3 abuts against the positioning block 53 to limit the positioning block 53. That is, when installing the valve cover body 3, it is inserted from the other side between the support base 51 and the upright plate 2 until the valve cover body 3 abuts against the positioning block 53. Then, the position of the valve cover body 3 is adjusted up and down so that the mounting hole corresponds to the through hole, and then it is fixed with the quick-change bolt 4.

[0022] In summary, this utility model, through the cooperation of the upright plate 2 and the quick-change bolt 4, can quickly fix the upright valve cover body 3, thereby enabling the drilling of holes on the valve cover body 3.
