Description

Technical Field

[0001] This application relates to the field of drilling equipment technology, and in particular to an automatic drilling device with a fire cap. Background Technology

[0002] The burner cap of a gas stove is one of the core components of the stove. It is usually located below the cooktop and directly supports the pot and forms a stable flame. As a detachable part of the upper part of the stove, the burner cap is mainly made of high-temperature resistant and corrosion-resistant copper alloy or cast iron. Its appearance design and performance directly affect thermal efficiency, energy saving effect and safety of use.

[0003] Figure 1 This is a processed flame arrestor. The flame arrestor comprises a one-piece cast body with support legs on opposite sides. The top of the flame arrestor also has several slots. The flame arrestor has three sets of first punches, five sets of second punches, one set of third punches, and one set of fourth punches. The three sets of first punches are evenly spaced around the center of the flame arrestor. The five sets of second punches are concentrically arranged with the first punches and are located entirely outside the first punches. The third and fourth punches are located inside the first punches.

[0004] To punch the slots in the flame cap, workers need to position the flame cap on a fixed base and then manually operate a drilling machine to punch the slots. Throughout the process, workers repeatedly need to place, adjust, and drill the flame cap. Furthermore, because the slots on the flame cap are complexly distributed, with different groups of holes and specific requirements for the position and number of holes in each group, workers need to use different drilling machines to ensure that the position and size of each slot meet the requirements. Utility Model Content

[0005] In order to improve the punching efficiency of multiple sets of punches on the flame cap, this application provides an automatic drilling device for the flame cap.

[0006] The automatic drilling device for fire caps provided in this application adopts the following technical solution: An automatic drilling device for a flame cap includes a rotating mechanism, multiple positioning mechanisms circumferentially arranged on the rotating mechanism for positioning the flame cap, a clamping mechanism for pressing the flame cap, and several drilling mechanisms arranged on the outside of the rotating workstation. The several drilling mechanisms include a first drilling assembly for processing a first punch, a second drilling assembly for processing a second punch, a third drilling assembly for processing a third punch, and a fourth drilling assembly for processing a fourth punch. The positioning mechanism includes a positioning base, a positioning seat, an insertion post arranged on the positioning seat and engaging with the flame cap, and a positioning post arranged on the positioning seat for the flame cap to be placed and abutted against.

[0007] By adopting the above technical solution, the rotating mechanism can drive the positioning mechanism to rotate. The multiple sets of positioning mechanisms are arranged circumferentially to facilitate the positioning and placement of the flame cap. The clamping mechanism can clamp the flame cap to prevent it from shaking during drilling. Different drilling components can process the first, second, third, and fourth punches of the flame cap respectively. The plug-in pin on the positioning seat is plugged into the flame cap and the positioning pin is used for the flame cap to be placed and abutted, which can accurately position the flame cap, thereby realizing automatic drilling of the flame cap and improving drilling efficiency.

[0008] Optionally, the rotating mechanism includes a fixed base, a rotating work plate rotatably mounted on the fixed base, and a rotating drive component for driving the rotating work plate.

[0014] Optionally, the drilling support is provided with a cooling assembly, which includes three sets of delivery pipes connected to coolant, and the ends of the delivery pipes correspond one-to-one with the three sets of first punch holes.

[0015] By adopting the above technical solution, the three sets of delivery pipes of the cooling component are connected to the coolant and their ends correspond one-to-one with the three sets of first punch holes. This can provide coolant for the processing of the first punch holes during the drilling process, playing a role in cooling and lubrication. This can reduce the friction and heat between the drill bit and the burner cap, and extend the service life of the drill bit.

[0016] Optionally, the clamping lever cylinder is a double-acting cylinder, and the rotary workstation is provided with a ventilation mechanism for driving the clamping lever cylinder. The ventilation mechanism includes a conveying component corresponding to the positioning mechanism, a rotary diverter valve connected to the conveying component and disposed on the work platform, and a gas conveying frame for guiding the air pipe.

[0017] By adopting the above technical solutions, the conveying components, rotary diverter valve, and gas conveying frame of the ventilation mechanism can efficiently and accurately supply air to the clamping lever cylinder, ensuring stable operation of the device and improving the working efficiency of the fire cap drilling.

[0018] Optionally, the conveying assembly includes a first pipe that connects to the air inlets of two sets of clamping lever cylinders, a second pipe that connects to the air outlets of two sets of clamping lever cylinders, a third pipe that connects to the rotary diverter valve, and a tee connector that connects the first pipe and the third pipe or the second pipe and the third pipe.

[0019] By adopting the above technical solution, the conveying component can effectively realize the intake and delivery of air to the two sets of clamping lever cylinders by using the connection method of the first pipe, the second pipe, the third pipe and the three-way connector.

[0020] Optionally, the output end of the rotary diverter valve is provided with a control air pipe, and the bottom of the gas delivery frame has a chamber for arranging the control air pipe.

[0031] The following is in conjunction with the appendix Figure 2-5 This application will be described in further detail.

[0032] This application discloses an automatic drilling device for fire caps.

The rotating mechanism 1 has five stations evenly spaced circumferentially, namely, a loading / unloading station, a first drilling station, a second drilling station, a third drilling station, and a fourth drilling station, with an angle of 72 degrees between adjacent stations.

[0034] Reference Figure 2 and Figure 3 The rotating mechanism 1 includes a fixed base 11, a rotating work plate 12 rotatably mounted on top of the fixed base 11, and a rotation drive 13 for driving the rotating work plate 12. The rotation drive 13 is a prior art cam divider, and the output end of the cam divider is coaxially fixed with the rotating work plate 12. The rotation drive 13 causes the rotating work plate 12 to perform intermittent rotation of 72 degrees.

[0035] The positioning mechanism 2 includes a positioning plate 21 and a positioning seat 22. The positioning plate 21 is a rectangular metal plate bolted to the outer side of the top surface of the rotating workstation 12, and the positioning seat 22 is a rectangular block fixed to the middle of the positioning plate 21. The positioning seat 22 is welded and fixed with plug-in pins 221 and two sets of positioning pins 222. The plug-in pins 221 and the flame cap 6 are plugged into each other, and the positioning pins 222 are used for positioning the outer support ears of the flame cap 6.

[0036] The clamping mechanism 3 includes clamping lever cylinders 31 fixed on opposite sides of the positioning seat 22. The output end of the clamping lever cylinder 31 is fixed with a clamping block 32 for clamping the top of the flame cap 6. Under the action of the clamping mechanism 3 and the positioning mechanism 2, the flame cap 6 is fixedly placed on the rotating work plate 12 to ensure the stability of the flame cap 6 during drilling.

[0037] Reference Figure 2 and Figure 4 The first drilling assembly 41 includes a drilling bracket 411, a drilling drive 412 mounted on the drilling bracket 411, and a three-axis drilling head 413 connected to the output end of the drilling drive 412. The drilling drive 412 is a combination of a drive motor and a feed cylinder, which provide rotational and feed power to the three-axis drilling head 413, respectively. A cooling assembly 45 is also provided on the drilling bracket 411. The cooling assembly 45 includes three sets of delivery pipes connected to coolant. The three sets of delivery pipes correspond one-to-one with the three sets of first punch holes 61 to be processed on the burner cap 6. Coolant is sprayed onto the punch holes by a water pump.

[0038] The second drilling assembly 42, the third drilling assembly 43, and the fourth drilling assembly 44 have the same overall structure as the first drilling assembly 41. The difference is that the drilling drive 412 of the second drilling assembly 42 is fixed with a five-axis drilling head 421 and has five sets of conveying pipes corresponding to the second punch 62; the drilling drive 412 of the third drilling assembly 43 is fixed with a first single-axis drilling head 431 and has a set of conveying pipes corresponding to the third punch 63; and the drilling drive 412 of the fourth drilling assembly 44 is fixed with a second single-axis drilling head 441 and has a set of conveying pipes corresponding to the fourth punch 64.

The ventilation mechanism 5 includes a conveying assembly 51, a rotary diverter valve 52, and a gas conveying frame 53.

[0040] The conveying assembly 51 corresponds one-to-one with the five positioning assemblies, used to connect the air inlet and outlet of the clamping lever cylinder 31 to the rotary diverter valve 52. The conveying assembly 51 includes a first pipe 511, a second pipe 512, a third pipe 513, and a three-way connector 514. The first pipe 511 connects to the air inlet of the clamping lever cylinder 31, the second pipe 512 connects to the air outlet of the clamping lever cylinder 31, and the three-way connector 514 connects two sets of the first pipe 511 and one set of the third pipe 513. The other end of the third pipe 513 is connected to the rotary diverter valve 52.

[0041] The rotary diverter valve 52 is prior art, and its specific structure will not be explained in this application. The stator and fixed base 11 of the rotary diverter valve 52 are fixed and coaxial with the output of the rotary drive component 13. The rotor of the rotary diverter valve 52 and the rotating station disk 12 rotate synchronously. Multiple sets of control air pipes 521 are provided on the top of the rotary diverter valve 52, and the air supply pipes are connected to the air source through the gas conveying frame 53. When the positioning mechanism 2 moves to the loading station, the air source is delivered from the stator to the rotor through the corresponding channel of the rotary diverter valve 52, and then to the clamping lever cylinder 31 of the loading station, driving the cylinder to perform clamping or releasing actions.

[0042] The gas delivery frame 53 is L-shaped, with one end fixed to the operating platform and the other end extending to the top of the rotary diverter valve 52. The gas delivery frame 53 has a chamber for the arrangement of the control gas pipe 521, which is connected to the gas source through the chamber.

[0043] To improve the stability of the gas delivery frame 53, two sets of adjusting screws 54 are also provided on the gas delivery frame 53. The two sets of adjusting screws 54 are symmetrically arranged along the axis of the rotary diverter valve 52. One end of the adjusting screw 54 is fixed to the top of the stator of the rotary diverter valve 52, and the other end passes vertically through the upper and lower end faces of the gas delivery frame 53. Adjusting nuts 541 for locking are provided on both end faces of the adjusting screws 54. Through the cooperation of the adjusting nuts 541 and the adjusting screws 54, the gas delivery frame 53 and the adjusting screws 54 are locked, thereby fixing the gas delivery frame 53 and the rotary diverter valve 52.

[0044] The implementation principle of the automatic drilling device for the flame cap 6 in this application embodiment is as follows: The operator places the flame cap 6 on the positioning seat 22 at the loading and unloading station, and then starts the clamping lever cylinder 31 to clamp and fix the flame cap 6; the rotating station plate 12 rotates, so that the flame cap 6 passes through the first drilling station, the second drilling station, the third drilling station, and the fourth drilling station in sequence, and finally returns to the loading and unloading station. The clamping lever cylinder 31 is operated to release the clamping of the flame cap 6, and the processed flame cap 6 is removed and put back into the flame cap 6 to be processed.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
