Description

Technical Field

[0001] This invention relates to the field of water distribution plate processing equipment, and more specifically, to a special drilling machine for perforating water distribution plates. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the water temperature. The tower body is often built in circular, rectangular, or polygonal shapes. There are two types of cooling towers: wet and dry. Based on the direction of air and water flow, cooling towers can be divided into counter-flow and cross-flow types. The principle of a cooling tower is to transfer heat from the water to the air and diffuse it into the atmosphere, thereby reducing the heat in the water. It is mainly used for air temperature control, manufacturing, and processing. The heat sink and water distribution plate are important components of a cooling tower. The main function of the heat sink is to extend the residence time of the cooling water and increase the heat exchange area to improve the heat exchange capacity. The main function of the water distribution plate is to evenly disperse the water before it is distributed onto the heat sink.

[0003] During the manufacturing process of water distribution boards, a drilling machine is typically used to create perforations on their surface to facilitate the assembly and installation of the boards using rods. While existing water distribution board drilling machines can quickly drill holes in the surface of the water distribution board using several drill bits, the fixed distance between adjacent drill bits results in a uniform perforation spacing, making it difficult to meet the diverse perforation needs of different water distribution boards and limiting their applicability. Therefore, this invention designs a dedicated perforation drilling machine for water distribution boards to solve the above problems. Summary of the Invention

[0007] As a preferred embodiment of the present invention, the air supply pipe is in the shape of a bent pipe, and an air source connector is fixedly connected to the end of the air supply pipe.

[0008] By setting up an air source connector, the air supply pipe can be connected to the air source equipment through the air source connector, so that the air source equipment can provide gas power to the pneumatic drill bit a and the pneumatic drill bit when they are drilling.

[0009] As a preferred embodiment of the present invention, the drive assembly includes a motor and a lead screw shaft. The motor is fixedly installed on the side of the processing table, the lead screw shaft is fixedly connected to the drive shaft of the motor, and a transmission seat is fixedly installed at the bottom end of the carrier, the transmission seat being threaded onto the outside of the lead screw shaft.

Then, by turning the locking stud forward using the knob block, the drill bit subframe and main drill bit frame are locked in place. When it is necessary to increase the perforation spacing on the water distribution plate surface, the locking stud is turned in the opposite direction to disengage it from the main drill bit frame. The stretched springs then pull the drill bit subframe and several pneumatic drill bits b upwards to reset them. This allows for changing the relative position between the pneumatic drill bits b and a, facilitating adjustment of the perforation spacing on the water distribution plate surface. This adapts to different water distribution plate perforation processing needs and expands the scope of application.

[0023] 2. This invention uses an operating turntable to rotate the rotating shaft in the forward direction, causing the gear ring to drive the transmission rack and drill bit frame to move downward, thereby performing perforation processing on the water distribution plate. The resistance generated by the tension spring helps to slow down the descent speed of the drill bit frame, improves the overall stability during the perforation processing of the water distribution plate, and ensures the processing effect of the perforation processing of the water distribution plate.

[0024] 3. The present invention uses a motor to drive the lead screw shaft to rotate, thereby driving the drive frame and the water distribution plate to slide laterally along the processing table, which facilitates the adjustment of the lateral position of the water distribution plate and makes it convenient to perform continuous perforation processing on each area of ​​the water distribution plate.

[0042] Working principle of the invention:

[0043] During use, the air supply pipe 209 is connected to the air source equipment through the air source connector 2094. The water distribution plate is placed on the positioning component 8. The short positioning angle steel 801 and the long positioning angle steel 802 can be used to position and block each side of the water distribution plate. According to the perforation processing requirements of the water distribution plate, when it is necessary to reduce the perforation spacing processed on the surface of the water distribution plate, the drill bit sub-frame 5 and several pneumatic drill bits b501 are pulled downwards, the spring 503 is stretched, and the pneumatic drill bit a30 is pulled downwards. After aligning with the pneumatic drill bit b501, use the knob block 505 to turn the locking stud 504 clockwise to lock and fix the drill bit sub-frame 5 to the drill bit main frame 3. When it is necessary to increase the perforation spacing on the surface of the water distribution plate, turn the locking stud 504 counterclockwise to disengage it from the drill bit main frame 3. The spring 503, which is in a stretched state, can be used to pull the drill bit sub-frame 5 and several pneumatic drill bits b501 upwards to reset it. Once the position adjustment of the pneumatic drill bit b501 is complete... Afterwards, the main solenoid valve 2091 and the corresponding branch solenoid valve 2093 are opened, so that the air source equipment provides gas power to the pneumatic drill bits a301 and b501 for drilling operations. The rotary table 2021 is used to rotate the rotating shaft 202 in the forward direction, so that the gear ring 203 drives the transmission rack 4 and the drill bit main frame 3 to move downward, thereby performing perforation processing on the water distribution plate. The resistance generated by the tension spring 205 helps to slow down the descent speed of the drill bit main frame 3 and improve the overall stability of the water distribution plate perforation processing. After the perforation processing is completed, the rotary table 2021 is used to rotate the rotating shaft 202 in the reverse direction, so that the gear ring 203 drives the transmission rack 4 and the drill bit main frame 3 to move upward and reset. The motor 701 drives the lead screw shaft 702 to rotate, so that the drive carrier 6 and the water distribution plate slide laterally along the processing table 1, thereby facilitating the adjustment of the lateral position of the water distribution plate and making it easier to perform perforation processing operations on each area of ​​the water distribution plate.
