Description

Technical Field

[0001] The invention relates to the field of water heater shell processing equipment, and in particular to an automatic rotary feeding device for producing household water heater components. Background Art

[0002] Water heaters are the most widely used water heaters at present. Based on the heating elements, they can be divided into electric heating and gas heating. The water heater is mainly composed of an outer shell, a heating assembly and electrical components. The heating elements and electrical components are located inside the outer shell. The outer shell is mainly composed of a top shell and a bottom shell. The top shell is usually provided with a touch panel for device control. For example, the water heater shell and the gas water heater disclosed in application number: CN202121209273.9. The water heater shell includes a top shell and a cover plate. The top shell includes a first flange. The cover plate can slide along the length direction of the first flange to the installation position and be fixed to the first flange. A first protrusion is provided on one of the first flange and the cover plate. The first protrusion can slide in contact with the other of the first flange and the cover plate and separate the first flange and the cover plate; a first avoidance hole for avoiding the first protrusion is provided on the other of the first flange and the cover plate.

[0003] The top shell and the bottom shell are connected and installed to form the entire shell. The top shell is usually made of metal. Holes corresponding to the screw holes of the bottom shell need to be processed on the metal frame of the top shell. The holes of the side holes need to be accurately drilled, otherwise they cannot correspond to the screw holes of the bottom shell, which makes it inconvenient to insert the screws.

[0004] Currently, the side hole processing of the metal shell of a water heater is usually done by manual loading. After manual loading, the position must be carefully adjusted to ensure the accurate drilling position. The metal shell of the water heater is then pressed from the side, and the pressure plate is tightened by locking screws to tighten the metal shell of the water heater. This clamping method is cumbersome and cannot be automated. It also has problems such as unstable processing dimensions and requires multiple tool adjustments. In view of the above, it is necessary to propose an automatic rotary loading device for the production of household water heater components to solve the above problems. Summary of the Invention

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] An automatic rotary feeding device for producing household water heater parts, such as Figure 1 As shown, it includes a base 1 and a positioning plate 2, the positioning plate 2 is slidably connected to the base 1, and two slide rails 28 are provided in parallel on the base 1. The positioning plate 2 is slidably connected to the base 1 through the slide rails 28, and the positioning plate 2 moves on the base 1 to form a loading station 3 and a processing station 4. A reciprocating drive part 5 is provided on the base 1 to drive the positioning plate 2 to move between the loading station 3 and the processing station 4. When actually used, the face shell 29 is placed on the positioning plate 2, and the reciprocating drive part 5 is used to move it to the processing station 4 for processing the side holes; when the face shell 29 is placed on the positioning plate 2, the positioning mechanism provided on the positioning plate 2 is used to align the face shell 29, and then when it is moved to the processing station 4, the clamping device 6 and the side The wall fixing device 7 fixes the height position of the face shell 29 and the side wall that needs to be processed. A hole-making drill bit 8 is further provided on the outside of the processing station 4. The hole-making drill bit 8 set on the side is used to perform hole-making operations on the side panel of the face shell 29. It can be understood that the hole-making drill bit 8 shown in the figure is synchronously driven by the equipment to approach the face shell 29 to punch holes; and the clamping device 6 presses the face shell 29 on the positioning plate 2 from the four corners of the panel; the side wall fixing device 7 is used to press and fix the opening part from the inner wall of the face shell 29. Since the side frame is to be opened, and the side frame of the water heater is in the shape of a long narrow strip and has a thin wall thickness, it is necessary to use the side wall fixing device 7 to press and fix the side of the face shell 29 from the inside;

[0023] like Figure 2 As shown, the positioning plate 2 is provided with a positioning mechanism that cooperates with the touch panel mounting hole on the face shell 29, and the positioning plate 2 is provided with four long holes 9. The long holes 9 are set along the diagonal of the touch panel mounting hole 30. Each long hole 9 is provided with a vertical rod 10, and the vertical rod 10 moves in the long hole 9. The four vertical rods 10 move in a centrally symmetrical manner. A synchronous driving mechanism for driving the vertical rod 10 to move is provided inside the positioning plate 2; in actual use, the synchronous driving mechanism brings the four vertical rods 10 together in the first state, and the four vertical rods 10 move away from each other and are stuck at the corner of the touch panel mounting hole 30 in the second state. The position positioning of the face shell 29 is achieved by utilizing the movement of the vertical rod 10 away from each other and cooperating with the touch panel mounting hole 30.

[0024] Specifically, the synchronous drive mechanism includes a drive disk 11, and the drive disk 11 is rotatably connected and arranged inside the positioning plate 2. The positioning plate 2 is provided with a cavity for preventing the drive disk 11 from moving. The upper end surface of the drive disk 11 is provided with an arc-shaped cam groove 12. The cam groove 12 is provided with four symmetrical strips, and each of them forms a cam with the lower end of a vertical rod 10. The drive disk 11 rotates to drive the four vertical rods 10 to move simultaneously along the direction of the long hole 9. The lower end of the vertical rod 10 is provided with an inverted T-shaped rod head, and the cross-sectional shape of the cam groove 12 is an inverted T-shape, so that the vertical rod 10 can be fixed in the cam groove 12 to prevent it from falling out. The middle part of the vertical rod 10 is placed in the long hole 9 and cooperates with it. Therefore, when the drive disk 11 rotates, it is restricted by the cam groove 12 and the long hole 9, so that the vertical rod 10 moves along the setting direction of the long hole 9. Figure 3 As shown, the circumferential side wall of the driving disk 11 is a worm gear tooth surface 13, and a first reduction motor 14 is further provided inside the positioning plate 2. A worm 15 is provided at the output end of the first reduction motor 14, and the worm 15 is meshed and connected with the worm gear tooth surface 13; when in use, the first reduction motor 14 rotates the driving disk 11 through the worm 15, so that the four vertical rods 10 move synchronously together or apart along the long strip hole 9. During actual positioning, the positioning plate 2 is located at the loading station 3. At this time, the four vertical rods 10 are controlled by the driving disk 11 to be in the first state. That is, they are gathered together, and then the face shell 29 is placed on the positioning plate 2, and the touch panel mounting hole 30 is placed outside the four vertical rods 10. At this time, the face shell 29 has not been aligned; then the driving disk 11 is rotated, and the four vertical rods 10 move to the second state, so that the four vertical rods 10 are stuck at the corners of the touch panel mounting hole 30. During the movement of the vertical rods 10, the face shell 29 can be aligned. It can be understood that this device uses the rotation of the driving disk to achieve the position positioning of the face shell, thus avoiding manual alignment operations.

[0025] The reciprocating mechanism then sends the face shell 29 to the processing station 4. Specifically, the reciprocating drive unit 5 includes a second reduction motor 16, a ball screw 17, and a slider; the ball screw 17 is rotatably connected and arranged on the base 1, and a second reduction motor 16 for driving its rotation is arranged at one end of the ball screw 17. The slider is fixedly arranged on the lower end surface of the positioning plate 2, and the slider is sleeved on the ball screw 17. The rotation of the ball screw 17 can drive the positioning plate 2 to move. In order to control the positioning plate 2 to reach the exact position and stop moving, a block can be set on the base 1, or a travel positioning mechanism similar to a travel switch, so that the face shell 29 can stop accurately when it reaches the processing station 4.

[0026] The first clamping device 6 is arranged at the four corners of the processing station 4, and includes a cylinder 18 and a pressure plate 19. The cylinder 18 is fixedly arranged on the side of the base 1, and the output shaft of the cylinder 18 is telescopically movable in a direction perpendicular to the positioning plate 2. A pressure plate 19 is provided at the end of the output shaft, and a flexible pad 20 is provided on the lower side of the pressure plate 19. In actual use, when the face shell 29 is placed on the positioning plate 2 and positioned after the vertical rod 10 of the positioning mechanism is expanded, it is moved into the processing station 4 by the reciprocating drive unit 5. The positioning plate 2 stops on the processing station 4 after touching the travel switch, and then the cylinders 18 at the four corners drive the pressure plate 19 to press down on the upper side of the face shell 29, clamping the face shell 29 against the positioning plate 2, and the flexible pad 20 on the lower side of the pressure plate 19 can flexibly press the face shell 29, which is placed on the face shell 29 to cause damage.

[0027] The side wall fixing device 7 is respectively arranged on both sides of the processing station 4, including a rotating shaft 21, a stop block 22, and a rotation driving part 23. The rotating shaft 21 is rotatably connected and arranged on the bottom plate. The stop block 22 is fixed on the rotating shaft 21. The stop block 22 corresponds to the position of the hole drill bit 8. The driving part drives the stop block 22 to rotate through the rotating shaft 21, and the stop block 22 is pressed tightly against the inner wall of the surface shell 29.

[0028] The side surface of the abutment block 22 includes a pressing plane 24, a first arc surface 25, and a second arc surface 26 connected in sequence. Figure 4 As shown, the radius of the first arc surface 25 is greater than that of the second arc surface 26, and an opening groove 27 is provided in a direction perpendicular to the tightening plane 24. The opening groove 27 passes through the tightening plane 24 and the first arc surface 25, and the second arc surface 26 is provided on the lower side of the opening groove 27. The rotation drive unit 23 is a driving motor; in actual use, the rotation drive unit 23 can drive the rotating shaft 21 to rotate at a fixed angle. When the surface shell 29 workpiece does not enter the processing station 4, the second arc surface 26 rotates toward the hole drill 8, and then the surface shell 29 workpiece enters the processing station 4. Since the radius of the second arc surface 26 is smaller than that of the first arc surface 25 Therefore, the second arc surface 26 does not touch the inner wall of the workpiece at this time. Before opening, the rotation drive part 23 is used to rotate the block 22 to a specific angle, so that the tightening plane 24 is tightly attached to the inner wall of the workpiece. Since the tightening plane 24 is arranged between the first arc surface 25 and the second arc surface 26, a principle similar to a cam protrusion can be formed when the block 22 rotates, so that the tightening plane 24 is squeezed on the inner wall of the workpiece, and then the hole-opening drill bit 8 moves to drill the workpiece. It can be understood that when the tightening plane 24 is attached to the inner wall of the workpiece, the opening groove 27 just reserves space for the drill bit to drill in.

[0029] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
