Description
Technical Field
[0001] This utility model relates to the technical field of cast iron pot blank processing, specifically a device for precise drilling of cast iron pot blanks. Background Technology
[0002] Cast iron pot blanks have a wide range of applications, covering home kitchens, catering industry, industrial manufacturing, and art manufacturing. They are used to make cooking utensils, mechanical parts, handicrafts, etc. They have good thermal conductivity, heat preservation, and durability, meeting the needs of different industries. However, during the processing, it is often necessary to drill holes in them using a drilling device.
[0003] According to the public announcement (CN222817992U), a positioning and drilling machine for cast iron pot blanks is disclosed. This technology discloses "a machine platform, with legs fixedly connected to the four corners of the bottom surface of the machine platform, a drilling mechanism on the upper side of the machine platform, a horizontal bar, diagonal bars fixedly connected to both ends of the horizontal bar, the bottom end of the diagonal bars fixedly connected to both sides of the machine platform, a sliding sleeve slidably connected to one side of the diagonal bar, a U-shaped rod on the lower side of the sliding sleeve, the sliding sleeve hinged at both ends of the U-shaped rod, and a sector worm gear fixedly connected to one end of the U-shaped rod, etc. The drilling component is hinged to the sliding sleeve through the U-shaped rod, and a sector worm gear is provided on the U-shaped rod. The sector worm gear realizes the angle adjustment of the U-shaped rod under the control of the worm gear, and realizes the self-locking function. It can not only realize the adjustment of the drilling angle, but also make the drilling angle perpendicular to the tangent of the through hole position on the arc surface of the pot blank, and make the angle adjustment more stable, preventing slippage and deviation during drilling and opening."
[0004] However, in the aforementioned comparative documents, the clamps cannot be adjusted according to the curved surface of the iron pot, resulting in insufficient clamping. The iron pot is prone to sliding and shifting during processing, which causes instability in the processing of the iron pot. This can lead to inaccurate drilling positions and inconsistent hole sizes, affecting product quality and even causing the product to be scrapped.
[0005] Therefore, this utility model provides a device for precise drilling of cast iron pot blanks. Utility Model Content
[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a device for precise drilling of cast iron pot blanks.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: a precision drilling device for cast iron pot blanks, comprising a worktable, a turntable rotatably connected to the upper part of the worktable, a clamping mechanism provided on the upper part of the turntable, the clamping mechanism comprising a central column fixedly connected to the upper end of the turntable, a first hydraulic cylinder fixedly connected to the side end of the central column, a slide bar fixedly connected to the upper part of the turntable, a slide plate fixedly connected to the output end of the first hydraulic cylinder, the surface of the slide bar slidably connected to the slide plate, a rotating seat rotatably connected inside the slide plate, a clamping block fixedly connected to the side end of the rotating seat, a liquid storage tank opened inside the clamping block, a sliding groove opened inside the clamping block, a piston slidably connected to the clamping block through the sliding groove, a push rod fixedly connected to the side end of the piston, and hydraulic oil filling the liquid storage tank and the sliding groove.

[0011] The technical effect of adopting the above-mentioned further solution is that by setting the second hydraulic rod to drive the drilling hydraulic cylinder to the drilling position, the drilling hydraulic cylinder can be rotated by the rotating frame so that the drilling hydraulic cylinder is perpendicular to the pot surface, and the drilling tool is used to drill holes on the surface of the iron pot blank.
[0012] In a preferred embodiment, the push rod has an arc-shaped rotating shaft inside, and the side end of the central column has a rotating groove. The central column is rotatably connected to the arc-shaped rotating shaft through the rotating groove. A pressure plate is fixedly connected to the side end of the arc-shaped rotating shaft, and a buffer pad is fixedly connected to the side end of the pressure plate.
[0013] The technical effect of adopting the above-mentioned further solution is that by setting the pressure plate to rotate according to the contact arc surface, it can better fit the surface of the iron pot blank. Because it can better fit the arc surface, the clamping force is more evenly distributed. In addition, a buffer pad is added to buffer the impact, which can reduce the indentation and damage to the surface of the iron pot and ensure the appearance quality of the iron pot.
[0014] This utility model provides a device for precise drilling of cast iron pot blanks. It has the following beneficial effects:
[0015] Through hydraulic oil transmission, multiple sets of pistons drive push rods to change length according to the arc surface and get closer to the arc surface, which greatly improves the fit between the clamp and the arc surface of the iron pot blank. This allows the device to clamp the iron pot blank more stably and avoids the iron pot blank from shaking due to unstable clamping during processing such as drilling, which would affect the drilling accuracy and quality.
[0016] The pressure plate can rotate according to the contact arc surface, thus better fitting the surface of the iron pot blank.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figures 1-4 As shown, this embodiment provides a technical solution: a precision drilling device for cast iron pot blanks, including a worktable 1, a turntable 2 rotatably connected to the upper part of the worktable 1, a clamping mechanism 3 provided on the upper part of the turntable 2, the clamping mechanism 3 including a central column 301 fixedly connected to the upper end of the turntable 2, a first hydraulic cylinder 302 fixedly connected to the side end of the central column 301, three first hydraulic cylinders 302 are provided, a slide bar 303 fixedly connected to the upper part of the turntable 2, three slide bars 303 are provided, a slide table 304 fixedly connected to the output end of the first hydraulic cylinder 302, the surface of the slide bar 303 is slidably connected to the slide table 304, the slide bar 303 and the slide table 304 are adapted to each other, a rotating seat 305 is rotatably connected inside the slide table 304, the slide table 304 and the rotating seat 305 are adapted to each other, a clamping block 306 is fixedly connected to the side end of the rotating seat 305, the clamping block 306 is internally connected to the rotating seat 305, and the clamping block 306 is internally connected to the rotating seat 305. The device includes a liquid storage tank 307 and a sliding groove 308 inside the clamping block 306. The liquid storage tank 307 is connected to the sliding groove 308. The clamping block 306 is slidably connected to a piston 309 through the sliding groove 308. The inner circumference of the sliding groove 308 at this point is equal to the outer circumference of the piston 309. A push rod 310 is fixedly connected to the side end of the piston 309. The liquid storage tank 307 and the sliding groove 308 are filled with hydraulic oil 311. By setting the clamping block 306, it can be adjusted and rotated to be tangent to the fixed arc surface according to the arc surface of different iron pots. Driven by the hydraulic oil 311, multiple sets of pistons 309 drive the push rod 310 to change the length and get closer to the arc surface according to the arc surface. This greatly improves the fit between the clamp and the arc surface of the iron pot blank, so that the device can clamp the iron pot blank more stably and avoid the iron pot blank shaking due to unstable clamping during processing such as drilling, which would affect the drilling accuracy and quality.
[0026] like Figure 2As shown: The bottom of the workbench 1 is fixedly connected to the first motor 4. The output end of the first motor 4 is fixedly connected to the turntable 2. The first motor 4 drives the iron pot blank to rotate and move the position to be drilled to one side of the drilling device, thus eliminating the need to readjust the angle and clamp and fix it.
[0027] like Figures 1-3 As shown: A bracket 5 is fixedly connected to the upper part of the workbench 1, providing support for the drilling assembly. A second hydraulic rod 6 is fixedly connected to the side end of the bracket 5, and a drilling base 7 is fixedly connected to the output end of the second hydraulic rod 6. The interior of the drilling base 7 is slidably connected to the bracket 5, and the drilling base 7 is compatible with the bracket 5. A second motor 8 is fixedly connected to the side end of the drilling base 7, and a worm gear 9 is fixedly connected to the output end of the second motor 8. A sector-shaped worm gear 10 meshes with the surface of the worm gear 9, and the worm gear 9 and the sector-shaped worm gear 10 are compatible. A rotating frame 11 is rotatably connected to the surface of the drilling base 7, and the drilling base 7 and the rotating frame 11 are rotatably connected. The frame 11 is adapted to the rotating frame 11. The surface of the fan-shaped turbine 10 is fixedly connected to the rotating frame 11. When the fan-shaped turbine 10 rotates, it drives the rotating frame 11 to rotate. A drilling hydraulic cylinder 12 is fixedly connected to the side end of the rotating frame 11. A driller 13 is fixedly connected to the output end of the drilling hydraulic cylinder 12. The drilling base 7 is moved above the drilling point of the iron pot by the second hydraulic rod 6. The second motor 8 is started to drive the fan-shaped turbine 10 to rotate. Thus, the drilling hydraulic cylinder 12 can be rotated by the rotating frame 11 until the drilling hydraulic cylinder 12 is perpendicular to the tangent of the drilling point on the pot surface. The driller 13 is then used to drill holes on the surface of the iron pot blank.
[0028] like Figures 3-4 As shown: The push rod 310 has an arc-shaped rotating shaft 14 inside, and the side end of the central column 301 has a rotating groove 15. The central column 301 is rotatably connected to the arc-shaped rotating shaft 14 through the rotating groove 15. The rotating groove 15 is adapted to the arc-shaped rotating shaft 14. The side end of the arc-shaped rotating shaft 14 is fixedly connected to a pressure plate 16, and the side end of the pressure plate 16 is fixedly connected to a buffer pad 17. The buffer pad 17 is made of rubber and has anti-slip textures on its surface. When the buffer pad 17 contacts the pot surface, the buffer pad 17 rotates at the arc-shaped rotating shaft 14 with the support of the pressure plate 16 and the rotating groove 15, so that the surface of the buffer pad 17 is tangent to the contact surface. At the same time, the buffer pad 17 undergoes a certain deformation. By setting it up, the pressure plate 16 can rotate according to the contact arc surface, so as to better fit the surface of the iron pot blank. Because it can better fit the arc surface, the clamping force is more evenly distributed, which can reduce the indentation and damage to the surface of the iron pot and ensure the appearance quality of the iron pot.
[0029] Working principle:
[0030] like Figures 1-4 As shown:
[0031] When in use: When the iron pot blank is placed on the slide table 304, the first hydraulic cylinder 302 drives the three slide tables 304 to move inward. When the push rod 310 contacts the position to be fixed, the clamping block 306 rotates on the slide table 304 through the rotating seat 305, so that the contact surface is tangent to it. At the same time, the push rod 310, which is first subjected to the pressure of the iron pot, drives the piston 309 to move inward, thereby pushing the hydraulic oil 311 to drive the piston 309, which is not in contact, to drive the push rod 310 to move outward, thereby changing the exposed length of the push rod 310 at different positions, so that it fits the curved surface of the iron pot better.
[0032] When the buffer pad 17 contacts the pot surface, the buffer pad 17 is supported by the pressure plate 16 and rotates at the arc-shaped shaft 14 via the rotating groove 15, so that the surface of the buffer pad 17 is tangent to the contact surface. At the same time, the buffer pad 17 undergoes a certain deformation. By setting it up, the pressure plate 16 can rotate according to the contact arc surface, thus better conforming to the surface of the iron pot blank. Because it can better conform to the arc surface, the clamping force is more evenly distributed. And through the buffer pad 17, the indentation and damage to the surface of the iron pot can be reduced, ensuring the appearance quality of the iron pot.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
