Description

Technical Field

[0001] The invention relates to production and processing related fields, and in particular to an automatic milling and drilling processing device and method for a gas stove burner. Background Art

[0002] A gas stove refers to a kitchen appliance that uses direct fire heating with gas fuels such as liquefied petroleum gas (liquid), artificial gas, and natural gas.

[0003] According to the gas source, gas stoves are mainly divided into liquefied gas stoves, coal gas stoves, and natural gas stoves. According to the stove eyes, they are divided into single stoves, double stoves, and multi-burner stoves.

[0004] The main component of a gas stove is the heat burner, which is a general term for a device that sprays fuel and air in a certain way for mixed combustion. The burner of a gas stove is more common, usually in a disc shape, with a combustion hole on the front or edge for supplying fuel;

[0005] During the production and processing of the burner, milling and drilling equipment is used to open the combustion-supporting holes. After searching, a gas stove burner automatic milling and drilling processing device is disclosed, with the announcement number: CN214518765U. A fire cover clamping mechanism is set at the center of the lower mounting plate, wherein the fire cover clamping mechanism pushes multiple clamping blocks to expand outward synchronously through the downward movement of the inverted wedge block to tighten the inner circumference of the fire cover to limit the position. The synchronous support of the support points of multiple clamping blocks can ensure the safety and reliability of the fire cover clamping process and improve the structural strength of the fire cover processing process. In addition, the gas hole milling and drilling mechanism is radially symmetrically set on the periphery of the fire cover clamping mechanism to mill and drill the gas holes on the fire cover, so that during the milling and drilling of the gas holes on the fire cover, the force of the milling drill in the radial position is balanced and not easy to deform. In addition, the servo drives the fire cover clamping mechanism to rotate to the corresponding angle position after each round of milling and drilling, and then cooperates with two sets of gas hole milling and drilling mechanisms to synchronize the milling and drilling of holes.

[0006] This device is a way to drill holes on the edge of the burner, but most existing burners still use the front hole opening method, so this device is not suitable for front hole opening;

[0007] Secondly, the device does not have a corresponding material return mechanism, so there is a certain risk when feeding and taking materials;

[0008] There is still a problem with opening holes on the front that does not exist in opening holes on the side. When milling and drilling, a certain amount of iron chips will be generated. The location of the iron chips is unpredictable and may exist in any position. If the iron chips exist on the burner, it may affect the processing quality. Summary of the invention

DETAILED DESCRIPTION

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0061] For example, see Figures 1 to 12 , an automatic milling and drilling device for a gas stove burner, comprising a workbench 1 and a plurality of legs 2 fixed to the bottom of the workbench 1, wherein a support plate 3 is fixed to the workbench 1;

[0062] The turntable 4 installed on the workbench 1 is rotated, the turntable 4 is equipped with a positioning assembly for clamping and fixing, and the workbench 1 is equipped with a material stripping assembly cooperating with the positioning assembly;

[0063] A hole-taking assembly, the hole-taking assembly is installed on the workbench 1, the hole-taking assembly is located on both sides of the turntable 4, and the hole-taking assembly is connected to a driving assembly installed at the bottom of the support plate 3;

[0064] A limiting strip 11 is fixed to one side of the workbench 1 and the turntable 4 .

[0065] In the embodiment of the present invention, those burners that have not been processed are defined as "materials". Then, the materials are securely placed on the workbench 1, and a certain thrust is applied to move the materials toward the center of the turntable 4.

[0066] When the material moves to the center of the turntable 4, the positioning assembly will be used to effectively clamp and fix the material to ensure that it will not move in the subsequent process.

[0067] This step is to allow the material to be driven by the turntable 4 and realize the operation of synchronous rotation with the turntable 4;

[0068] Start the hole-picking assembly. After starting, the hole-picking assembly will enter a continuous working state. During this period, the hole-picking assembly will be driven down by the driving assembly to drill holes and the driving assembly will drive the turntable 4 to rotate. These two operations cooperate with each other, and the purpose is to allow the material to achieve intermittent equal-angle rotation. In this process, drilling operations are performed on the material to achieve equidistant circumferential drilling of the material.

[0069] Finally, after all processing is completed, the positioning component releases the material. At this time, with the help of the material return component, the processed material is moved out of the processing position. This is done to avoid the continuous operation of the hole-taking component causing harm to the staff in subsequent operations.

[0070] The hole extraction assembly includes two slide plates 14 slidably mounted on the workbench 1 via a slide rod 12, and the two slide plates 14 are arranged opposite to each other;

[0071] A second guide rod 15 is fixed on each of the two slide plates 14, and a second spring 13 is sleeved on the second guide rod 15;

[0072] A plurality of drilling bits are equidistantly mounted on opposite sides of the two slides 14, and a fourth gear 39 is coaxially fixed on the rotating shafts of the plurality of drilling bits, and the plurality of fourth gears 39 mesh with each other. A third gear 37 is also rotatably mounted on the slide 14, and the third gear 37 meshes with one of the fourth gears 39. A second motor 33 is also fixed on the slide 14, and the output shaft of the second motor 33 is coaxially fixed with the third gear 37.

[0073] The two slide plates 14 are fixed by a U-shaped force-bearing plate 27, and the force-bearing plate 27 cooperates with the driving assembly;

[0074] A chip removal assembly is installed at the bottom of the slide plate 14 .

[0075] In the embodiment of the present invention, the second motor 33 is driven, and when the second motor 33 is working, the third gear 37 is driven to rotate through the real output shaft. When the third gear 37 rotates, the fourth gear 39 is driven to rotate through the fourth gear 39, so that the drilling bit is driven to rotate through the rotation of the fourth gear 39;

[0076] Among them, a large and small gear is arranged between the third gear 37 and the fourth gear 39 to increase the rotation speed of the fourth gear 39, and the plurality of fourth gears 39 are meshed in sequence;

[0077] When the driving assembly is working, it drives the force plate 27 to descend, so as to drive the two slide plates 14 to descend synchronously through the third gear 37, and then drives the drilling drill to descend to drill holes in the material. The chip removal assembly can remove the iron chips on the material under the drilling drill to prevent the iron chips from causing any adverse effects during the drilling operation. This design not only improves the efficiency of the equipment, but also ensures the safety of operation.

[0078] The chip removal assembly includes an air cylinder 35 rotatably mounted on the bottom of the slide plate 14, a transmission plate 38 is also mounted on the bottom of the slide plate 14, the transmission plate 38 is coaxially fixed with the third gear 37, and the movable rod of the air cylinder 35 is rotatably connected to the eccentric portion of the transmission plate 38;

[0079] A temporary storage box 34 is fixed at the bottom of the slide plate 14 , the output port of the air cylinder 35 is connected to the temporary storage box 34 , and injection components 40 are fixed on both sides of the drilling bit, and the injection components 40 are connected to the temporary storage box 34 through a delivery pipe 36 .

[0080] In the embodiment of the present invention, when the third gear 37 rotates, the transmission plate 38 is driven to rotate synchronously, and the rotation of the transmission plate 38 drives the movable rod of the air cylinder 35 to reciprocate, that is, the movable rod of the air cylinder 35 reciprocates to continuously pump gas into the temporary storage box 34 through the air cylinder 35, and the gas is then transported to the injection member 40 through the delivery pipe 36, and is sprayed to the designated position through the injection member 40;

[0081] As another implementation of this embodiment, the air cylinder 35 is fixed, and then the movable rod of the air cylinder 35 is rotatably connected to the eccentric part of the transmission plate 38 through a connecting plate rotatably connected thereto. In this way, the air cylinder 35 is in a stationary state during the pumping process, and the effect achieved is the same as that of the above embodiment;

[0082] Among them, iron filings are often generated during the drilling operation. These iron filings will affect the processing accuracy when opening adjacent holes to a certain extent. Therefore, when designing, it is necessary to consider how to effectively remove these iron filings to ensure that the accuracy of continuous holes is not affected.

[0083] The driving assembly includes a cam 29 rotatably mounted on the bottom of the support plate 3, a worm wheel 28 is coaxially fixed on the rotating shaft of the cam 29, and a worm 49 meshing with the worm wheel 28 is rotatably mounted on one side of the worm wheel 28; a roller is rotatably mounted on one protruding end of the cam 29 to reduce friction;

[0084] A second gear 30 is coaxially fixed on the worm 49, an incomplete gear 31 is rotatably mounted on one side of the second gear 30, a first motor 32 is fixed at the bottom of the support plate 3, and the output shaft of the first motor 32 is coaxially fixed with the incomplete gear 31;

[0085] The worm gear 28 is connected to the turntable 4 via a transmission assembly.

[0086] In the embodiment of the present invention, the first motor 32 is started first. After the first motor 32 starts working, the incomplete gear 31 is driven to rotate through its output shaft. When the toothed portion of the incomplete gear 31 rotates to a position meshing with the second gear 30, the second gear 30 is driven to rotate. When the toothed portion of the incomplete gear 31 is disengaged from the second gear 30, there is no longer a transmission relationship between the two, so that the second gear 30 presents an intermittent rotation state.

[0087] During this period, the transmission ratio between the incomplete gear 31 and the second gear 30 is set to workbench 1: workbench 1 to meet specific work requirements;

[0088] During the rotation of the No. 2 gear 30, the worm wheel 28 is driven to rotate by the worm 49, and the rotation of the worm wheel 28 drives the movement of the cam 29. When the raised part of the cam 29 rotates to a position facing the force plate 27, the force plate 27 is driven to stand upright and move downward. As the force plate 27 descends, the two slide plates 14 also follow it to move upright and descend. In this process, the descending action of the slide plate 14 applies a pulling force to the No. 2 spring 13, causing it to store a certain amount of elastic potential energy. When the raised part of the cam 29 rotates to a position away from the force plate 27 again, the elastic potential energy stored in the No. 2 spring 13 is released, driving the two slide plates 14 and the force plate 27 to stand upright and rise and return to their initial positions. In this way, the cam 29 completes one circle of rotation, allowing the two slide plates 14 to complete a reciprocating motion.

[0089] In addition, when the worm gear 28 rotates, the turntable 4 is driven to rotate a certain angle through the transmission assembly.

[0090] The transmission assembly includes a No. 2 transmission rod 26 coaxially fixed to one side of the worm gear 28, a No. 2 transmission shaft 21 is rotatably mounted at the bottom of the workbench 1, the No. 2 transmission shaft 21 is connected to the No. 2 transmission rod 26 via a No. 2 transmission chain 23, and the No. 2 transmission shaft 21 is connected to the turntable 4 via a No. 2 bevel gear set 22;

[0091] Among them, the second bevel gear set 22 includes a bevel gear ring and an incomplete bevel gear that mesh with each other. The bevel gear ring is coaxially fixed with the turntable 4, and the incomplete bevel gear is coaxially fixed with the second transmission shaft 21. Two limiting rollers 25 for limiting the second transmission chain 23 are rotatably installed on the workbench 1.

[0092] In the embodiment of the present invention, when the worm gear 28 rotates, the second transmission rod 26 is driven to rotate, and the second transmission rod 26 drives the second transmission shaft 21 to rotate through the second transmission chain 23, and the second transmission shaft 21 drives the incomplete bevel gear to rotate, and when the toothed part of the incomplete bevel gear is meshed with the bevel gear ring, the turntable 4 is driven to rotate through the bevel gear ring, and when the toothed part of the incomplete bevel gear is disengaged from the bevel gear ring, no transmission relationship is sent between the two.

[0093] When the toothed portion of the incomplete bevel gear is meshed with the bevel gear ring, the incomplete gear 31 and the second gear 30 are in a disengaged state;

[0094] The second transmission chain 23 is also provided with a protective shell for protection;

[0095] As another implementation of this embodiment, the limit strip 11 on the turntable 4 is set in a symmetrical state, and its application scenario is to use a single-group hole-picking component. Because the turntable 4 with a double-group hole-picking component only needs to rotate 180° to complete the processing, while the turntable 4 with a single-group hole-picking component needs to rotate 360°. The advantage of using a single-group hole-picking component is that the production cost is low, and the double-group hole-picking component is used to improve the processing efficiency. This embodiment can be used when a double-group hole-picking component is used.

[0096] The positioning assembly includes two clamping blocks 41 slidably mounted on the turntable 4, and the two clamping blocks 41 are arranged opposite to each other;

[0097] A bidirectional screw rod 16 is rotatably mounted at the bottom of the turntable 4. Two No. 2 threaded sleeves 45 threadably matched with the bidirectional screw rod 16 are sleeved on the bidirectional screw rod 16. The two No. 2 threaded sleeves 45 are fixed to two clamping blocks 41.

[0098] Two No. 1 transmission rods 19 and two No. 1 transmission shafts 17 are rotatably installed at the bottom of the workbench 1. The No. 1 transmission shaft 17 and the No. 1 transmission rod 19 are connected by a No. 1 bevel gear set 18. A linkage groove 47 is opened on the opposite side of the two No. 1 transmission shafts 17. The linkage groove 47 cooperates with a linkage block 48 fixed to one end of the bidirectional screw rod 16. The two No. 1 transmission rods 19 are connected by a No. 1 transmission chain 20.

[0099] The turntable 4 is also provided with a travel limit assembly, and the travel limit assembly is connected to the bidirectional screw rod 16 .

[0100] In the embodiment of the present invention, a hand wheel is coaxially fixed to one end of the longer No. 1 transmission rod 19 away from the No. 1 bevel gear set 18. Of course, it can also be driven directly by a motor. The specific method is not specifically limited by the present invention.

[0101] One of the No. 1 transmission rods 19 is driven to rotate, and when the No. 1 transmission rod 19 rotates, the other No. 1 transmission rod 19 is driven to rotate synchronously through the No. 1 transmission chain 20, so that the two No. 1 transmission rods 19 rotate synchronously, and then the two No. 1 transmission shafts 17 are driven to rotate synchronously through the No. 1 bevel gear set 18;

[0102] When the No. 1 transmission shaft 17 rotates, the No. 3 gear 37 drives the linkage block 48 to rotate, so as to drive the bidirectional screw 16 to rotate through the linkage block 48. When the bidirectional screw 16 rotates, the two No. 2 threaded sleeves 45 and the two clamping blocks 41 move relative / oppositely through the threaded cooperation with the two No. 2 threaded sleeves 45, so as to clamp and release the material through the relative and opposite movement of the clamping blocks 41.

[0103] Among them, whether a single-group hole-taking assembly or a double-group hole-taking assembly is adopted, this embodiment can realize the rotation of the bidirectional screw rod 16 through the cooperation of one of the linkage grooves 47 and the linkage block 48 when the turntable 4 and the bidirectional screw rod 16 rotate 180° or 360°. This design not only improves the flexibility of the system, but also increases the reliability of the system, so that the present invention shows excellent performance in practical applications;

[0104] It should be noted that the first bevel gear set 18 in this embodiment includes two bevel gears meshing with each other, and the two bevel gears are coaxially fixed to the first bevel gear set 18 and the first transmission rod 19 respectively.

[0105] The travel limit assembly includes a limit plate 24 that penetrates the turntable 4 and slidably cooperates with the turntable 4. The limit plate 24 is rotatably mounted with a screw rod 43 toward one side of the bidirectional screw rod 16. The screw rod 43 is sleeved with a No. 1 threaded sleeve 44 that is threadedly cooperated with the screw rod 43.

[0106] A third transmission shaft 42 is rotatably mounted on the bottom of the turntable 4 , and the third transmission shaft 42 is connected to the bidirectional screw rod 16 and the screw rod 43 via two third bevel gear sets 46 .

[0107] In the embodiment of the present invention, when the bidirectional screw 16 rotates, one of the No. 3 bevel gear sets 46 drives the No. 3 transmission shaft 42 to rotate, and when the No. 3 transmission shaft 42 rotates, the other No. 3 bevel gear set 46 drives the screw 43 to rotate. When the screw 43 rotates, it drives the limit plate 24 to rise / fall vertically by cooperating with the thread of the No. 1 threaded sleeve 44;

[0108] The two third bevel gear sets 46 respectively include a first bevel gear and a second bevel gear meshing with each other and a third bevel gear and a fourth bevel gear meshing with each other. The first bevel gear and the second bevel gear are coaxially fixed with the third transmission shaft 42 and the bidirectional screw 16. The third bevel gear and the fourth bevel gear are coaxially fixed with the third transmission shaft 42 and the screw 43.

[0109] This embodiment is applied when a single set of hole extraction components is used.

[0110] The material stripping assembly comprises two transmission plates 6 rotatably mounted on the workbench 1, a No. 1 gear 10 is rotatably mounted on the rotating shafts of the two transmission plates 6, and a No. 1 roller 5 is rotatably mounted on the ends of the two No. 1 gears 10;

[0111] Two rack plates 9 are slidably mounted on the workbench 1 , and the two rack plates 9 are meshed with two No. 1 gears 10 . A No. 1 guide rod 7 is fixed to the opposite side of the two rack plates 9 , and a No. 1 spring 8 is sleeved on the No. 1 guide rod 7 .

[0112] In the embodiment of the present invention, when the material moves toward the center of the rotating disk 4, it will first contact the No. 1 roller 5. As the No. 1 roller 5 moves, the transmission plate 6 is driven to open. When the two transmission plates 6 are opened, they rotate in opposite directions, and when rotating, the No. 1 gear 10 is driven to rotate. When the No. 1 gear 10 rotates, it drives the two rack plates 9 to move relative to each other through the meshing with the rack plate 9, so that the No. 1 spring 8 is pulled up when the two rack plates 9 move relative to each other, so that the No. 1 spring 8 reserves elastic potential energy;

[0113] When the material moves to the center of the turntable 4, the material is limited and fixed by the positioning assembly. After the processing is completed, the positioning assembly releases the fixation of the material and releases the elastic potential energy stored in the two No. 1 springs 8 to drive the two rack plates 9 to move in opposite directions, and drive the two transmission plates 6 to rotate relative to each other through engagement with the No. 1 gear 10 to extrude the material in the direction of the rack plate 9.

[0114] The present invention also provides a method for automatic milling and drilling of a gas stove burner. The method for automatic milling and drilling of a gas stove burner adopts the automatic milling and drilling device for a gas stove burner, and comprises the following steps:

[0115] Step 1: Place the material in the limiting strip 11 and push it to the center of the turntable 4;

[0116] Step 2: Use the positioning component to limit and fix the material, and then start the driving component;

[0117] Step 3: The driving assembly drives the hole-taking assembly to descend, and the hole-taking assembly performs a drilling process on the material. After the drilling process, the turntable 4 and the material are driven to rotate a certain angle to repeat this motion state to complete the circumferential equidistant drilling of the material;

[0118] Step 4: Release the limit fixation of the material through the positioning component, and drive the material to the processing position through the material return component to complete the processing.
