[0001] This application relates to the field of drilling and tapping fixtures, and more particularly to a drilling and tapping fixture for a gas stove base. Background Technology

[0002] refer to Figure 1 The gas stove base 1 includes a base body 11, a delivery pipe 12 connected to the outer wall of the base body 11 and communicating with the inner cavity of the base body 11, and mounting supports 13 axially symmetrically arranged on the outer wall of the base body 11. The top surface of the base body 11 has multiple mounting holes 111, and the extension direction of the delivery pipe 12 is perpendicular to the axial direction of the base body 11. The mounting support 13 has a lug plate 131 extending away from the base body 11, and the lug plate 131 has mounting through holes 1311. To improve the machining accuracy of the gas stove base 1, it is often necessary to clamp and fix it during machining.

[0003] In response to the aforementioned technologies, the inventor provides a drilling and tapping fixture for a gas stove base. Utility Model Content

[0004] In order to improve the machining accuracy of gas stove base, this application provides a drilling and tapping fixture for gas stove base.

[0005] The drilling and tapping fixture for a gas stove base provided in this application adopts the following technical solution:

[0006] A drilling and tapping fixture for a gas stove base includes a frame, a mounting plate rotatably mounted on the top surface of the frame, a flipping mechanism for driving the mounting plate to rotate horizontally, and a clamping mechanism mounted on the mounting plate. The top surface of the mounting plate is provided with a support frame for arranging the gas stove base, and the top surface of the support frame is provided with a support assembly for the bottom surface of the gas stove base to abut against. The clamping mechanism includes a clamping member and a clamping drive member for driving the clamping member to move. The clamping member has a pressing part that abuts against the top surface of a lug plate.

[0007] By adopting the above technical solution, during the processing of the gas stove base, the gas stove base is first placed against the top surface of the support assembly to ensure its balance. A clamping drive then pushes the clamping component downwards, causing its pressing part to abut against the top plate of the lug plate on the gas stove base. This presses the gas stove base firmly against the top surface of the support frame. The mounting holes of the gas stove base are then processed. Finally, a flipping mechanism drives the mounting frame to flip, facilitating the processing of the delivery pipe. The cooperation between the clamping mechanism and the support assembly helps reduce the probability of the gas stove base shifting during processing, improving the processing accuracy of the gas stove base.

[0008] Optionally, the clamping drive includes a clamping cylinder mounted on the top surface of the mounting plate, a mounting fork of the piston rod of the clamping cylinder, and a transmission rod mounted on the top surface of the mounting plate. The clamping component includes a connecting plate and clamping claws that abut against the gas stove base.

[0009] By adopting the above technical solution, the specific structure of the clamping drive component is disclosed. The piston rod of the clamping cylinder is pushed upward, thereby driving the clamping component hinged with the mounting fork to press downward, clamping the gas stove base arranged on the top surface of the support plate. This reduces the probability of the gas stove base moving during processing and improves the processing accuracy of the gas stove base.

[0010] Optionally, the connecting plate has a hinge hole that mates with the mounting fork, the hinge hole being a strip-shaped hole.

[0011] By adopting the above technical solution, the setting of the strip hole helps the connection between the connecting rod and the mounting fork, so that the mounting fork can smoothly drive the connecting plate to perform downward or upward movements, ensuring the stability and reliability of the clamping process.

[0012] Optionally, the flipping mechanism includes a first rotating seat rotatably mounted on the top surface of the frame, a drive motor for driving the first rotating seat to rotate horizontally, and a second rotating seat rotatably mounted on the top surface of the frame and arranged opposite to the first rotating seat, wherein the rotation axis of the first rotating seat coincides with the rotation axis of the second rotating seat.

[0013] By adopting the above technical solution, the specific structure of the flipping mechanism is disclosed. The first rotating seat is driven by a drive motor to rotate horizontally, and the rotation of the first rotating seat drives the second rotating seat to rotate horizontally, thereby realizing the flipping of the mounting plate, which helps to improve the processing accuracy of the gas stove base's conveying pipe.

[0014] Optionally, the top surface of the mounting plate is provided with at least two rows of clamping mechanisms arranged in opposite directions, and the clamping mechanisms in adjacent rows are staggered, with no less than three clamping mechanisms in one row.

[0015] By adopting the above technical solution, at least two rows of clamping mechanisms are arranged on the top surface of the mounting plate, with adjacent rows of clamping mechanisms staggered and each row having no fewer than three clamping mechanisms. This helps to improve the processing efficiency of the gas stove base and increase the space utilization of the mounting top surface.

[0016] Optionally, the top surface of the support frame is further provided with a positioning post for insertion into the mounting through hole.

[0017] By adopting the above technical solution, the setting of the positioning column helps to restrict the gas stove base arranged on the top surface of the support frame, which helps to improve the fixing efficiency of the gas stove base on the top surface of the support frame, ensures that the gas stove base maintains a stable position during drilling, and improves processing accuracy and efficiency.

[0018] Optionally, the support assembly includes several support pads arranged on the top surface of the support frame. When the positioning post is inserted into the mounting through hole, the several support pads abut against the bottom surface of the gas stove base.

[0019] By adopting the above technical solution, the setting of the support pad helps to keep the gas stove base arranged on the top surface of the support frame in a balanced state, reduces the probability of movement during the processing of the gas stove base, and helps to improve the processing accuracy of the gas stove base.

[0020] Optionally, the top surface of the support frame is provided with a limiting plate, the support assembly is installed on the top surface of the limiting plate, and the limiting plate is also provided with positioning posts on both sides of the support assembly for insertion into the mounting through holes.

[0021] By adopting the above technical solution, setting a limiting plate on the top surface of the support frame and installing support components and positioning posts on the limiting plate helps to provide support for the gas stove base arranged on the top surface of the limiting plate, ensuring the gas stove base is in a balanced state and helping to restrain the gas stove base. The setting of the limiting plate helps to improve the clamping efficiency of the gas stove base on the top surface of the support frame, and improves the processing accuracy and efficiency of the gas stove base.

[0022] Optionally, the bottom surface of the limiting plate is provided with a mounting slider, and the top surface of the support frame is provided with a mounting groove for arranging the mounting slider. The limiting plate and the support frame are connected and fixed by screws.

[0023] By adopting the above technical solution, the limit plate can be quickly installed and removed from the top surface of the support frame through the cooperation between the installation slider and the installation groove, which helps to repair and replace the limit plate.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. A drilling and tapping jig for a gas stove base, wherein a clamping drive unit drives a clamping component to press the gas stove base against the top surface of a support assembly, thereby machining the mounting holes of the gas stove base; and a flipping mechanism flips the mounting plate to machine the delivery pipe of the gas stove base. This helps to reduce the probability of the gas stove base shifting during machining, thereby improving the machining accuracy of the gas stove base.

[0026] 2. The positioning posts help to limit the movement of the gas stove base, improve the cooperation efficiency between the gas stove base and the support components, and improve the processing efficiency and precision of the gas stove base.

[0027] 3. By arranging at least two rows of back-to-back clamping mechanisms on the mounting plate and staggering the adjacent clamping mechanisms, with no less than three clamping mechanisms in each row, it helps to improve the processing efficiency of the gas stove base by the drilling and tapping jig.

[0037] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0038] This application discloses a drilling and tapping fixture for a gas stove base.

[0039] Example 1

[0040] Reference Figure 2 A drilling and tapping fixture for a gas stove base includes a frame 2, a mounting plate 3 rotatably mounted on the top surface of the frame 2, a flipping mechanism for driving the mounting plate 3 to rotate horizontally, and a clamping mechanism mounted on the top surface of the mounting plate 3. The top surface of the mounting plate 3 has at least two rows of clamping mechanisms arranged in opposite directions, with each row containing at least three clamping mechanisms. Adjacent rows of clamping mechanisms are staggered. In this embodiment, the top surface of the mounting plate 3 has two rows of clamping mechanisms, with one row containing four clamping mechanisms and the other row containing three.

[0041] Reference Figure 3 and Figure 4 The mounting plate 3 is a rectangular plate, and its top surface is provided with a support frame 31 for accommodating the gas stove base 1. The support frame 31 has a U-shaped cross-section and includes a top support plate 311 and support columns 312 arranged on the bottom surface of the top support plate 311. The support frame 31 is fixed to the top surface of the mounting plate 3 with screws. The top surface of the top support plate 311 is provided with a support component 32 for abutting against the bottom surface of the gas stove base 1. The support component 32 includes several support pads 321 installed on the bottom surface of the top support plate 311 and adapted to the bottom surface of the gas stove base 1. The top surface of the top support plate 311 also has positioning holes 3111 on both sides of the support component 32, and the top support plate 311 has positioning columns 33 inserted into the mounting through holes 1311 of the gas stove base 1 in the positioning holes 3111, and the height of the positioning columns 33 is lower than the depth of the mounting through holes 1311. When the positioning pin 33 is inserted into the mounting through hole 1311, the bottom surface of the gas stove base 1 abuts against the top surface of the support pad 321, thereby keeping the gas stove base 1 in a horizontal state and reducing the probability of the gas stove base 1 shifting during processing. In this embodiment, there are four support pads 321.

[0042] Reference Figure 5 and Figure 6The clamping mechanism is used to press the gas stove base 1 against the top surface of the supporting top plate 311. The clamping mechanism includes a clamping member 51 and a clamping drive member 52 for driving the clamping member 51. The clamping drive member 52 includes a clamping cylinder 521 mounted on the top surface of the mounting plate 3, a mounting fork 522 arranged on the piston rod of the clamping cylinder 521, and a transmission rod 523 arranged on the top surface of the mounting plate 3. The clamping member 51 includes a connecting plate 511 hinged to the mounting fork 522 and a clamping claw 512 connected to the side of the connecting plate 511 away from the mounting fork 522. The connecting plate 511 has a hinge hole 5111 that mates with the mounting fork 522, and the hinge hole 5111 is a strip-shaped hole. The clamping claw 512 has a pressing part 5121 that abuts against the top plate of the lug plate 131 of the gas stove base 1. The gas stove base 1 is limited by the pressing part 5121, reducing the probability of movement during the processing of the gas stove base 1. The end of the transmission rod 523 away from the mounting plate 3 is hinged to the side of the connecting plate 511 near the mounting fork 522, thereby ensuring the normal functioning of the clamping member 51.

[0043] refer to Figure 2 A flipping mechanism is arranged on the top surface of the frame 2. The flipping mechanism includes a first rotating seat 41 rotatably mounted on the top surface of the frame 2, a drive motor 42 mounted on the top surface of the frame 2 for driving the first rotating seat 41 to rotate horizontally, and a second rotating seat 43 rotatably mounted on the top surface of the frame 2 and arranged opposite to the first rotating seat 41. The first rotating seat 41 has a first mounting block 411 that abuts against the bottom surface of the mounting plate 3. The first mounting block 411 has a threaded hole, and one side of the mounting plate 3 is fixed to the first mounting block 411 of the first rotating seat 41 by screws. The second rotating seat 43 has a second mounting block 431 that abuts against the bottom surface of the mounting plate 3. The second mounting block 431 has a threaded hole, and the other side of the mounting plate 3 is fixed to the second mounting block 431 of the second rotating seat 43 by screws. In this embodiment, the flipping mechanism drives the mounting plate 3 to flip at an angle of 90°.

[0044] Combination Figures 1 to 6The implementation principle of the drilling and tapping fixture for a gas stove base 1 in this embodiment is as follows: During the processing of the gas stove base 1, the mounting through hole 1311 of the lug plate 131 on the gas stove base 1 is first inserted and engaged with the positioning post 33 on the mounting plate 3. At this time, the bottom of the gas stove base 1 abuts against the top surface of the support pad 321, thereby making the gas stove base 1 horizontal. Then, the clamping cylinder 521 drives the clamping member 51 to press down and press the gas stove base 1 tightly against the top surface of the support frame 31, thereby processing the mounting hole 111 on the top surface of the gas stove base 1. Then, the mounting plate 3 is flipped by the flipping mechanism to process the inner wall of the delivery pipe 12 of the gas stove base 1. The setting of the positioning post 33 and the support assembly 32 helps to reduce the probability of the gas stove base 1 moving during processing, thereby improving the processing accuracy of the gas stove base 1.

[0045] Example 2

[0046] Compared with Embodiment 1, the drilling and tapping fixture of the gas stove base 1 in this embodiment is the same as that in Embodiment 1, except that the installation method of the support component 32 and the positioning column 33 is different.

[0047] refer to Figure 7 and Figure 8 The support frame 31 has a limiting plate 34 on its top surface, and the support assembly 32 is mounted on the top surface of the limiting plate 34. The limiting plate 34 also has positioning posts 33 on both sides of the support assembly 32 for insertion into the mounting through holes 1311 of the gas stove base. The bottom surface of the limiting plate 34 has a mounting slider 341, and the top surface of the support frame 31 has a mounting groove 313 for accommodating the mounting slider 341. The limiting plate 34 also has threaded holes. When the limiting plate 34 is mounted on the mounting groove 313 on the top surface of the support frame 31 via the mounting slider 341, the limiting plate 34 and the support frame 31 are connected and fixed by screws. In this embodiment, the mounting slider 341 is a T-shaped slider, and the mounting groove 313 is a T-shaped groove.
