Description

Technical Field

[0001] This utility model belongs to the field of water heater manufacturing technology, and in particular relates to an automatic grinding device for the bottom cover of the inner tank with a pneumatic positioning clamp. Background Technology

[0002] An air source heat pump water heater is a device that uses low-temperature heat energy from the air to heat water. It absorbs heat from the air through components such as a compressor, evaporator, condenser, water tank, and circulation pump, and transfers it to the water to achieve a heating effect. The water in the water tank absorbs heat through the condenser and becomes warm or hot for human use. The water tank mainly consists of the inner tank body and bottom covers at both ends of the inner tank body. During the production of the water tank inner tank, the bottom covers are mostly sealed and fixed to the inner tank body by welding. Before the actual welding operation, in order to ensure the welding quality, the edges of the bottom covers need to be ground.

[0003] In existing technologies, when grinding the bottom cover, small dust particles generated during the grinding process are scattered freely in the operating environment, reducing the air quality. Furthermore, the bottom cover in existing technologies is curved, making it difficult to clamp and position. In addition, the grinding equipment needs to be operated manually, which increases the labor intensity of workers.

[0004] To address these issues, we have developed an automatic grinding device for the inner liner bottom cover with a pneumatic positioning clamp. Utility Model Content

[0005] The purpose of this invention is to provide an automatic grinding device for the bottom cover of an inner liner with a pneumatic positioning clamp. A fan creates negative pressure inside the chamber to draw dust in, preventing it from scattering. A cylinder, in conjunction with a rotating plate and a ball joint, clamps and positions the bottom cover. A motor rotates the bottom cover to achieve automatic grinding. This solves the problems of existing technologies where small dust particles are scattered in the operating environment during grinding, reducing air quality, and where existing bottom covers are difficult to clamp and position, requiring manual operation of the grinding equipment, increasing worker workload.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an automatic grinding device for the bottom cover of an inner liner with a pneumatic positioning clamp. It includes a dust removal mechanism comprising a housing. The right wall of the housing is rotatably connected to a door via a hinge. A mounting box is fixed to the left wall of the door. A dust filter plate is inserted inside the mounting box. A fan is fixed to the right wall of the housing at the location of the dust filter plate, and the housing is connected to the outside via the fan. The pneumatic positioning grinding mechanism includes a placement plate located below the bottom cover body and fixed to the upper side inside the housing. Multiple universal balls fixed to the placement plate are arranged in a circumferential array along the lower edge of the bottom cover body. A motor is located on one side of the bottom cover body. A grinding disc is fixed to the power output shaft of the motor. A mounting block is located above the bottom cover body. Multiple rotating plates are arranged in a circumferential array outside the mounting block. A motor is located above the mounting block, and a cylinder is located above the motor. Ventilation holes are evenly distributed on the placement plate.

[0008] The present invention is further provided with a handle lock fixed on the front side of the right wall of the box door, and screw sleeves fixed at the four corners of the lower wall of the box body. The screw sleeves are connected to screw rods by internal threads, and the lower end of the screw rods is fixed with a base plate.

[0009] The present invention is further provided that the side wall of the mounting box has a perforation, the door corresponding to the location of the perforation has a through hole, and a protective net is fixedly provided on the right wall of the fan.

[0010] The present invention is further configured such that an L-shaped plate and a mounting plate are fixedly provided at the upper and lower ends of the cylinder, respectively, the L-shaped plate is fixedly connected to the housing, and the motor and the electric motor are both fixedly connected to the mounting plate.

[0011] The present invention is further configured such that guide rods fixed to the mounting plate are symmetrically provided on the left and right sides of the cylinder, and guide sleeves fixed to the L-shaped plate are provided on the outer clearance of the guide rods.

[0012] The present invention is further configured such that a rectangular block is fixed on the power output shaft of the motor, a rectangular plate is provided on the outer side of the rectangular block with clearance fit and is detachably fixed to the mounting block, a circular plate is fixed on the lower end of the rectangular block with clearance fit to the mounting block, a pressure sensor is provided below the circular plate, and a flange is fixed on the edge of the lower end of the mounting block.

[0013] The present invention is further configured such that a stop rod is rotatably connected to the lower end of the rotating plate, and a connecting block fixed to the mounting block is rotatably connected to the upper end of the rotating plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, by setting up a fan and a filter plate, creates a negative pressure state inside the chamber during grinding. At this time, the dust generated during grinding is drawn into the chamber under negative pressure. Under the filtering effect of the filter plate, the dust is trapped inside the chamber and collected, while the airflow is discharged to the outside of the chamber. Compared with the prior art, the combination of fan and filter plate can achieve dust collection and filtration, reduce the phenomenon of dust drifting in the operating environment, and reduce the impact of dust on the operating environment.

[0016] 2. This utility model, by setting up a cylinder, motor, rotating plate, electric motor, and grinding disc, places the bottom cover body above multiple universal balls, causing the grinding disc to rotate at high speed. This causes the cylinder to extend, driving the rotating plate to descend until the stop rod abuts against the inner edge of the bottom cover body, thus achieving the effect of clamping and positioning the bottom cover body. The cylinder drives multiple rotating plates to position the bottom cover body, thus using a pneumatic method to conveniently clamp and position the bottom cover body. At the same time, due to the rotation of the grinding disc, the bottom cover body rotates and is ground under the cooperation of the motor, eliminating the need for excessive manual intervention in the grinding operation and reducing the labor intensity of workers.

Detailed Implementation

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model is an automatic grinding device for the bottom cover of the inner liner with a pneumatic positioning clamp. It includes a dust removal mechanism 1, which includes a box 101. A rectangular groove is opened on the box 101 at the location of the box door 103. The right wall of the box 101 is rotatably connected to the box door 103 by a hinge. The hinge is located at the rear end of the box door 103, so that the box door 103 can rotate relative to the box 101. The left wall of the box door 103 is fixedly provided with an installation box 106, which provides an installation platform for the dust filter plate 105. The dust filter plate 105 is inserted into the installation box 106 for dust filtration. A fan 102 is fixedly provided on the right wall of the box 101 at the location of the dust filter plate 105. The box 101 is connected to the outside through the fan 102. The fan 102 is used to draw out the air inside the box 101 to form a negative pressure state, so that the dust can be sucked into the box 101 through the ventilation hole 205a by the negative pressure.

[0030] Specifically, a handle lock 103a is fixedly provided on the front side of the right wall of the box door 103. The box door 103 can be opened or closed by operating the handle lock 103a. Screw sleeves 101a are fixedly provided at the four corners of the lower wall of the box body 101. The screw rods 104 are connected to the internal threads of the screw sleeves 101a. The lower end of the screw rods 104 is fixedly provided with a base plate 104a. By operating the base plate 104a to rotate, the corresponding screw rods 104 are rotated, so that all four base plates 104a are in contact with the ground, and the dust removal mechanism 1 can be stably placed on the ground.

[0031] The side wall of the mounting box 106 has a perforation 106a, and the door 103 corresponding to the location of the perforation 106a has a through hole 103b. The right wall of the fan 102 is fixed with a protective net 102a, which can be made of metal mesh, to provide protection for the fan 102. The combination of the through hole 103b and the perforation 106a allows the air inside the housing 101 to be blown out by the fan 102 when the fan 102 is working, thereby creating a negative pressure inside the housing 101.

[0032] The operation process of this embodiment is as follows: During grinding, the fan 102 blows the airflow inside the housing 101 out of the housing 101. At this time, the inside of the housing 101 is in a negative pressure state. The dust generated by grinding enters the inside of the housing 101 through the ventilation hole 205a. Under the continuous operation of the fan 102, the airflow carrying dust passes through the perforation 106a, the dust filter plate 105, and the through hole 103b in sequence and is discharged from the housing 101. During this process, when the airflow carrying dust passes through the dust filter plate 105, the dust filter plate 105 filters the dust in the airflow and traps the dust inside the housing 101.

[0033] When it is necessary to clean the dust inside the housing 101, the dust inside the housing 101 can be cleaned by operating the handle lock 103a and opening the door 103. The dust filter plate 105 can also be cleaned or replaced.

[0034] Example 2

[0035] Please see Figure 1 , Figure 5 , Figure 6 and Figure 7This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: the pneumatic positioning and grinding mechanism 2 includes a placement plate 205 located below the bottom cover body 3 and fixed inside the upper side of the housing 101. Multiple universal balls 205b, fixed to the placement plate 205, are arranged in a circumferential array along the lower wall of the bottom cover body 3. The balls in the universal balls 205b contact the bottom cover body 3. A motor 204 is located on one side of the bottom cover body 3. A grinding disc 204a is fixed on the power output shaft of the motor 204. The motor 204 drives the grinding disc 204a to rotate, thereby achieving grinding of the bottom cover. The edges of the cover body 3 are polished. A mounting block 207 is provided on the top of the bottom cover body 3. The mounting block 207 has a square cross-section. Multiple rotating plates 206 are arranged in a circular array on the outside of the mounting block 207. The lower end of the rotating plate 206 is inclined outward. A motor 203 is provided on the top of the mounting block 207 to provide power for the rotation of the bottom cover body 3. A cylinder 201 is provided on the top of the motor 203 to provide power for the lifting and lowering of the rotating plate 206. Ventilation holes 205a are evenly opened on the placement plate 205 so that when the inside of the box 101 is in a negative pressure state, dust can enter the box 101 through the ventilation holes 205a.

[0036] Specifically, L-shaped plate 201a and mounting plate 202 are fixedly provided at the upper and lower ends of cylinder 201, respectively. L-shaped plate 201a is fixedly connected to housing 101, and motor 203 and motor 204 are both fixedly connected to mounting plate 202.

[0037] The cylinder 201 is symmetrically provided with guide rods 202a fixed to the mounting plate 202 on the left and right sides. The guide rods 202a are provided with guide sleeves 201b fixed to the L-shaped plate 201a with clearance fit. The cooperation between the guide rods 202a and the guide sleeves 201b can prevent the mounting plate 202 or the L-shaped plate 201a from being subjected to horizontal force, which would cause damage to the cylinder 201.

[0038] A rectangular block 203a is fixed on the power output shaft of the motor 203. A rectangular plate 207a, which is detachably fixed to the mounting block 207, is provided on the outer side of the rectangular block 203a with a clearance fit. A circular plate 209, which is clearance fit with the mounting block 207, is fixed on the lower end of the rectangular block 203a. A pressure sensor 208 is provided below the circular plate 209. The pressure sensor 208 is linked with the controller and provides real-time feedback of the pressure value to the control system. A flange 207b is fixed on the edge of the lower end of the mounting block 207. The flange 207b is set so that when the rotating plate 206 moves up and hangs down naturally, it contacts the flange 207b. In this state, the rotating plate 206 is in a state where the lower end is tilted outward. In this state, it is convenient for the lower end of the rotating plate 206 to expand outward when it moves down, without moving closer to each other and tightening.

[0039] The lower end of the rotating plate 206 is rotatably connected to a stop rod 206a. In order to increase the friction between the stop rod 206a and the bottom cover body 3, a rubber to increase the friction can be fixed on the outside of the stop rod 206a. In this state, the rubber abuts against the bottom cover body 3. The upper end of the rotating plate 206 is rotatably connected to a connecting block 206b that is fixed to the mounting block 207.

[0040] The operation process of this embodiment is as follows: During grinding, the cylinder 201 retracts, causing the rotating plate 206 to move upward. At this time, the bottom cover body 3 is placed above the universal ball 205b. The motor 204 is controlled to work, driving the grinding disc 204a to rotate. Then, the cylinder 201 extends, causing the rotating plate 206 to move downward. When the rotating plate 206 moves downward and contacts the lower wall inside the bottom cover body 3, as the cylinder 201 extends, the abutment rod 206a moves outward on the lower wall inside the bottom cover body 3 and presses against the edge of the bottom cover body 3. At the same time, the pressure sensor 208 detects the pressure. When the pressure reaches the preset value, the cylinder 201 stops extending, and the high-speed rotating grinding disc 204a contacts the edge of the bottom cover body 3. Then, the motor 203 works, driving the rotating plate 206 to rotate, causing the bottom cover body 3 to rotate above the universal ball 205b, thus realizing the grinding of the bottom cover body 3.

[0041] It should be noted that motor 203, electric motor 204, and cylinder 201 are all controlled by the controller. At the same time, motor 203, electric motor 204, and cylinder 201 are all connected to the controller in a conventional manner, which will not be elaborated on here. Furthermore, motor 203, electric motor 204, cylinder 201, and the controller are all existing technologies, and will not be limited here.
