Description

Technical Field

[0001] This utility model relates to the field of tooling technology for machine hole systems, and in particular to a tooling for a regulator cover with a machine hole system. Background Technology

[0002] In fields such as automotive engines, hydraulic systems, and precision instruments, the regulator cover is a key component for pressure control and flow regulation. Its surface features a series of holes (such as mounting holes, oil passage holes, and positioning holes), forming the core structure that ensures the regulator's assembly accuracy and functional reliability. The machining of these holes must meet stringent dimensional tolerances, positional tolerances, and perpendicularity requirements; otherwise, it can lead to excessive assembly clearances and valve core jamming. Machining these holes is a crucial step in the regulator cover manufacturing process.

[0003] However, traditional tooling for regulator cover hole systems has certain drawbacks. For example, the positioning pins and bolt limiting components of traditional tooling are mostly fixed welded structures, and their positions cannot be adjusted. They can only be used for regulator covers with a single hole layout, which results in a narrow applicability of the tooling and a lack of practicality. Utility Model Content

[0004] The purpose of this utility model is to provide a special tooling for machining holes in regulator covers, which can determine the position of regulator covers and lock them, thereby effectively improving the machining accuracy requirements and thus increasing the product qualification rate. It can also fix regulator covers of different sizes within a certain range, thereby improving the applicability of the tooling.

[0005] To achieve the above objectives, a special tooling for the adjustment cover machining hole system is provided, comprising:

[0006] The base has a first threaded rod rotatably connected to its inner surface, a slider threadedly connected to the outer surface of the first threaded rod, a threaded post fixedly connected to the upper surface of the slider, a nut threadedly connected to the outer surface of the threaded post, a disc block fixedly connected to one end of the first threaded rod, a limit block fixedly connected to the other end of the first threaded rod, a first spring provided on the outer surface of the first threaded rod, a hexagonal rotating block slidably connected to the outer surface of the first threaded rod, a pin fixedly connected to the outer surface of the hexagonal rotating block, and a socket provided on the outer surface of the base.

[0008] According to the aforementioned special tooling for a regulator cover machine hole system, the upper surface of the base is provided with a sliding groove, and the inner surface of the sliding groove is slidably connected to the slider.

[0009] According to the aforementioned special tooling for adjusting cover machine hole system, the upper end of the positioning pin is provided with an opening groove, and the inner surface of the opening groove is adapted to the internal hexagon bolt block.

[0010] According to the aforementioned tooling for a regulator cover bore system, the number of the first threaded rods is four and they are distributed in a circular array.

[0011] According to the aforementioned special tooling for the adjustment cover machine hole system, the outer surface of the disc block is rotatably connected to the base, and the outer surface of the limiting block is slidably connected to the hexagonal rotating block.

[0012] According to the aforementioned tooling for a regulator cover machine hole system, the inner surface of the insertion hole is adapted to the pin post.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0028] Reference Figure 1-6This utility model provides a special tooling for the machine hole system of an adjuster cover, comprising: a base 1, a first threaded rod 2 rotatably connected to the inner surface of the base 1, a slider 3 threadedly connected to the outer surface of the first threaded rod 2, a threaded post 4 fixedly connected to the upper surface of the slider 3, a nut 5 threadedly connected to the outer surface of the threaded post 4, a disc block 6 fixedly connected to one end of the first threaded rod 2, a limit block 7 fixedly connected to the other end of the first threaded rod 2, a first spring 8 provided on the outer surface of the first threaded rod 2, and a sliding connection between the outer surface of the first threaded rod 2 and the machine hole system. There is a hexagonal rotating block 9, and a pin post 10 is fixedly connected to the outer surface of the hexagonal rotating block 9. The outer surface of the base 1 is provided with a socket 11, and the upper surface of the base 1 is provided with a sliding groove 21. The inner surface of the sliding groove 21 is slidably connected to the slider 3 to limit the movement of the slider 3. There are four first threaded rods 2 arranged in a circular array. The outer surface of the disc block 6 is rotatably connected to the base 1. The outer surface of the limiting block 7 is slidably connected to the hexagonal rotating block 9. The inner surface of the socket 11 is adapted to the pin post 10 to facilitate the rotation and limiting of the first threaded rods 2.

[0029] The upper surface of the base 1 is provided with a positioning groove 12. The inner surface of the positioning groove 12 is movably connected with a positioning pin 13. The inner surface of the positioning pin 13 is threadedly connected with a second threaded rod 14. The upper end of the second threaded rod 14 is fixedly connected with an internal hexagon bolt block 15. The lower end of the second threaded rod 14 is fixedly connected with a limit plate block 16. The outer surface of the second threaded rod 14 is rotatably connected with a trapezoidal block 17. The inner surface of the positioning pin 13 is slidably connected with a support block 18. The upper surface of the support block 18 is fixedly connected with a inclined block 19. The outer surface of the inclined block 19 is fixedly connected with a second spring 20. The upper end of the positioning pin 13 is provided with an opening groove 22. The inner surface of the opening groove 22 is adapted to the internal hexagon bolt block 15. To facilitate the movement of the internal hexagonal bolt block 15, the inner surface of the positioning groove 12 contacts the support block 18 to prevent the positioning pin 13 from loosening and falling off. The outer surface of the limiting disc block 16 is rotatably connected to the trapezoidal block 17, and the outer surface of the trapezoidal block 17 is slidably connected to the inclined block 19.

[0030] Working principle: In use, according to the position of the hole on the regulator cover, first insert the positioning pin 13 into the corresponding positioning groove 12. Then, use the hexagonal handle to rotate the internal hexagonal bolt block 15, driving the second threaded rod 14 to drive the trapezoidal block 17 to slide along the inclined surface on the inclined block 19, thereby causing the support block 18 to extend outward and compressing the second spring 20, thus abutting against the inner wall of the positioning groove 12, thereby fixing the positioning pin 13. Then, pull the hexagonal rotating block 9 outward and compress the first spring 8, thereby driving the insertion pin 10 to disengage from the corresponding insertion hole 11. Then, rotate the hexagonal rotating block 9, and under the limiting action of the limiting block 7, drive the first threaded rod 2 to rotate. At this time, the slider 3 will... Move the threaded post 4 to the other hole position on the adjuster cover, then release the hexagonal swivel block 9. Under the rebound force of the first spring 8, the pin post 10 will be inserted into the corresponding insertion hole 11, thereby limiting the rotation of the first threaded rod 2 to prevent loosening. Then, align the holes on the adjuster cover with the positioning pin 13 and the threaded post 4 respectively and pass them through. The adjuster cover can then be limited on the positioning pin 13 and the threaded post 4. Then, screw the nut 5 into the threaded post 4 to fix the adjuster cover on the base 1 to ensure machining accuracy. The position adjustment of the positioning pin 13 and the threaded post 4 can fix adjuster covers of different sizes within a certain range, thereby improving the applicability of the tooling.
