Abstract
Description
Technical Field
[0001] This utility model relates to the field of preheater technology, and in particular to a component manufacturing device for an air preheater. Background Technology
[0002] As a crucial heat exchange device in industrial boiler systems, the manufacturing precision of air preheaters directly impacts their thermal efficiency and operational stability. Traditional component production often faces challenges such as insufficient positioning accuracy and low processing efficiency in the drilling process. Existing technologies mostly employ fixed clamps with manual feed mechanisms, requiring repeated adjustments to the workpiece position and posing a risk of accumulated positioning errors. Furthermore, the cumbersome process of changing conventional drill bit clamping structures hinders continuous operation efficiency; the unloading of processed workpieces largely relies on manual operation, resulting in low automation and safety hazards. Additionally, the lack of effective vibration damping during equipment operation leads to drill bit swaying, causing hole diameter deviations, while insufficient anti-slip performance of the clamps can cause workpiece displacement, affecting processing quality. While some improvements utilize servo motor drives or CNC systems to optimize positioning accuracy, these significantly increase equipment costs and require highly skilled operators, hindering widespread application in small and medium-sized manufacturing enterprises. Therefore, there is an urgent need to develop a production device that combines high precision, high efficiency, and ease of operation to meet the process requirements of mass production of air preheater components while reducing equipment investment and maintenance costs.

[0028] An adjusting block 109 is also installed on the base 101. A slide rail 201 is provided on the adjusting block 109. A first clamp 202 and a second clamp 203 are fitted on the slide rail 201. By adjusting the distance between the first clamp 202 and the second clamp 203, the drilling position of the workpiece 303 to be drilled can be adjusted.
[0029] The first fixture 202 has a fixing hole 204 in the horizontal direction, and the drilling area of the workpiece 303 to be drilled is fitted with the fixing hole 204. The second fixture 203 has a drilling hole 205 in the vertical direction, and the drill bit 108 passes through the drilling hole 205 to complete the drilling process of the workpiece 303 to be drilled.
[0030] The second fixture 203 has a fixing groove 206, which is engaged with the fixing area of the workpiece 303 to be drilled.
[0031] Furthermore, in a preferred embodiment of the present invention, a feeding cylinder 207 is also installed on the mounting plate 102. A pusher head 208 is fixed to the telescopic end of the feeding cylinder 207. The pusher head 208 can pass through the fixing hole 204 to push the drilled workpiece out of the fixing hole 204.
[0032] Furthermore, in a preferred embodiment of the present invention, the pusher head 208 is made of rubber material.
[0033] Furthermore, in a preferred embodiment of the present invention, a guide post 209 is also installed on the base 101, and a guide sleeve 301 is provided on the push plate 104, with the guide post 209 embedded in the guide sleeve 301.
[0034] Furthermore, in a preferred embodiment of the present invention, both the first clamp 202 and the second clamp 203 are locked onto the slide rail 201 by locking bolts 304.
[0035] Furthermore, in a preferred embodiment of the present invention, a cushioning pad 302 is provided at the bottom of the base 101.
[0036] Furthermore, in a preferred embodiment of the present invention, the slide rail 201 of the adjusting block 109 is provided with a laser scale, and the bottom of the first clamp 202 and the second clamp 203 are respectively provided with pointers for quantitative adjustment of the clamp spacing.
[0037] Furthermore, in a preferred embodiment of the present invention, the snap-fit connector 107 adopts a magnetic locking structure, including an electromagnet at the end of the rotating shaft 106 and an iron insert at the tail of the drill bit 108, which enables quick replacement of the drill bit by attracting it through electricity.
[0038] Furthermore, in a preferred embodiment of the present invention, the workpiece contact surface of the second clamp 203 is provided with anti-slip texture.
[0039] It should be noted that the workflow of the air preheater accessory production device is as follows: First, the operator places the workpiece 303 to be drilled into the fixing hole 204 of the first clamp 202, so that the drilling area of the workpiece 303 is fitted and positioned with the fixing hole 204. At the same time, the fixing area at the other end of the workpiece 303 is embedded into the fixing groove 206 of the second clamp 203 to ensure stable clamping of the workpiece 303. The distance between the first clamp 202 and the second clamp 203 is precisely adjusted by the laser scale on the side of the slide rail 201 and the pointer on the bottom of the clamp to match the length of the workpiece 303 and the target hole position. After adjustment, the clamp is fixed by locking bolts. After the equipment is started, the push-pull cylinder 103 pushes the push plate 104 to move forward linearly along the guide column 209. The guide sleeve 301 cooperates with the guide column 209 to ensure the stability of the movement. At the same time, the rotary motor 105 drives the rotary shaft 106 to rotate at high speed, driving the clamped drill bit 108 to rotate synchronously. When the push plate 104 moves forward to the set position, the drill bit 108 passes through the drilling hole 205 of the second clamp 203 to precisely drill the workpiece 303. After drilling is completed, the push-pull cylinder 103 retracts and resets, and the drill bit 108 exits the workpiece 303. Subsequently, the unloading cylinder 207 is activated, and its telescopic end pushes the rubber pusher head 208 through the fixing hole 204 of the first clamp 202, smoothly pushing out the processed workpiece 303, realizing automated unloading. If the drill bit 108 needs to be replaced, the old drill bit can be released and the new drill bit can be attracted by the magnetic locking structure after power is cut off, and the replacement can be completed quickly. Throughout the process, the buffer rubber pad 302 at the bottom of the base 101 absorbs the vibration of the equipment, and the anti-slip texture on the contact surface of the second clamp 203 further prevents the workpiece 303 from sliding, ensuring processing accuracy.
[0040] In summary, this device achieves high-precision hole position adjustment through the cooperation of the laser scale on the slide rail 201 and the clamp pointer, and ensures drilling straightness by combining the guide column 209, significantly improving processing accuracy. Automated drilling is achieved through the linkage of the push-pull cylinder 103 and the rotary motor 105, and automatic unloading is achieved with the unloading cylinder 207, greatly improving production efficiency. The clamp fixed by locking bolts, combined with anti-slip texture and buffer pads 302, effectively reduces processing vibration and workpiece 303 displacement, ensuring processing stability. The magnetic clamp connector 107 allows for quick replacement of the drill bit 108, and the slide rail 201 can be adjusted to accommodate workpieces 303 of different sizes, enhancing equipment flexibility. The rubber pusher head 208 prevents damage to the workpiece 303. The overall structure is simple and reliable, reducing production costs and maintenance difficulty while ensuring processing quality.
[0041] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
