An embedded cross-over upper pressing roller structure for a single-end precision milling machine for wooden windows

Abstract

An embedded straddle-type upper pressure roller structure for a single-end precision milling machine for wooden windows belongs to the field of machining technology. The pressure roller of the embedded straddle-type upper pressure roller and the roller table are arranged vertically opposite each other on the single-end precision milling machine, clamping and feeding the wooden window. This invention uses a spring to connect the embedded straddle-type upper pressure roller and the scissor-lifting platform. This structure changes the range of preload force on the wooden window by changing the type of spring. The spring is easy to replace and has low maintenance costs. By adjusting the type of spring and the height of the scissor-lifting platform, adaptive clamping of wooden windows of different thicknesses or materials can be achieved. The spring spacing adjustment mechanism can independently adjust the compressible stroke and initial pressure of the spring, adjusting the levelness of the embedded straddle-type upper pressure roller to ensure the shape accuracy during wooden window processing. Furthermore, by adjusting the type of spring and the height of the scissor-lifting platform, the stress limit on the wooden window can be further controlled.

Description

Technical Field

[0001] This invention belongs to the field of mechanical processing technology, specifically relating to an embedded straddle-type upper pressure roller structure for a single-end precision milling machine for wooden windows. Background Technology

[0002] Solid wood is increasingly used in the furniture industry due to its unique texture and properties. Wooden windows are an important component of solid wood furniture. In the field of woodworking machinery processing technology, after the wooden windows are framed, end grooves need to be machined using an end milling machine to install sealing strips. The traditional processing method is to manually feed the wooden window. The new process is to improve the machine tool with roller table and upper pressure roller to achieve automatic processing. However, this method can cause the machine tool door to be unable to open, resulting in difficulties in machine tool replacement and maintenance (the blades need to be replaced weekly). In addition, due to the different pressure ranges required by different tree species, the rigid upper pressure roller will cause poor adaptability of the pressure on the wooden window. Furthermore, the traditional wooden window pressing equipment composed of multiple sets of pressure rollers also has the problem of not being able to level, which will reduce the shape accuracy of the wooden window. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides an embedded straddle-type upper pressure roller structure for a single-end precision milling machine for wooden windows.

[0004] The technical solution adopted in this invention is: an embedded straddle-type upper pressure roller structure for a single-end precision milling machine for wooden windows, including a roller table, an embedded straddle-type upper pressure roller and a single-end precision milling machine; the pressure roller of the embedded straddle-type upper pressure roller and the roller of the roller table are arranged vertically opposite each other at the single-end precision milling machine, and the wooden window can be clamped and fed through the pressure roller and the roller.

[0005] Compared with the prior art, the present invention has the following advantages:

[0006] 1. This invention adopts an embedded straddle-type upper pressure roller structure for a single-end precision milling machine. This structure can be raised and lowered by a scissor lift platform, allowing the embedded straddle-type upper pressure roller to descend to a height flush with the roller table. This structure makes it easier to open the machine tool door and facilitates machine tool maintenance. The roller of this structure is supported at both ends by a straddle-type crossbeam and a column, which is more conducive to structural rigidity. While ensuring support at both ends, the straddle design can also effectively avoid interference problems that may occur when wooden windows are fed in a single-end precision milling machine.

[0007] 2. This invention uses a spring-loaded connection to embed a straddle-type upper pressure roller and a scissor-type lifting platform. The advantage of this structure is that the range of preload force on the wooden window can be changed by changing the type of spring. Moreover, the spring in this structure is easy to replace and has low maintenance costs compared to traditional gas springs or pneumatic pressure rollers. By adjusting the type of spring and the height of the scissor-type lifting platform, adaptive clamping of wooden windows of different thicknesses or materials can be achieved.

[0008] 3. The present invention employs a spring spacing adjustment mechanism, which can individually adjust the compressible stroke and initial pressure of the spring. The four spring spacing adjustment mechanisms are placed at the four corners of the base plate embedded in the straddle-type upper pressure roller, which can adjust the levelness of the embedded upper pressure roller, thereby ensuring the shape accuracy during the processing of wooden windows. In conjunction with adjusting the type of spring and the height of the scissor lift platform, the stress limit of the wooden window can be further controlled. Attached Figure Description

Each pressure roller 44 is rotatably mounted on a corresponding pressure roller frame 43. The pressure roller frames 43 in the same row or column are mounted on a column 42. Each column 42 is L-shaped, and the lower end of each column 42 is welded and fixed to the base plate 41. The middle part of the straddle-type crossbeam 45 passes around the single-end precision milling machine 5 and spans above all columns 42 and connects with all The upper surface of the column 42 is fixedly connected. The two ends of the crossbeam 45 are bent downward and set on the front and rear sides of the single-end milling machine tool 5 and fixed on the slider of the guide rail slider 46 to achieve up and down sliding.

Two slots are opened on the base plate 41 at the corresponding positions of the compression springs 13 at the front and rear ends of the scissor lift platform 1. The four lower connecting rod connecting blocks 48 and the lower connecting blocks 49 of the compression springs are respectively welded to the slots of the base plate 41. The compression springs 13 are connected to the four upper connecting blocks 12 and the lower connecting blocks 49 of the compression springs of the scissor lift platform 1 to connect the scissor lift platform 1 and the embedded crossbeam upper pressure roller 4. The four lower connecting rod connecting blocks 48 are used to connect the compression spring spacing adjustment mechanism 2.

[0022] like Figure 1 , Figure 2 As shown, four spring spacing adjustment mechanisms 2 are connected between the four lower connecting blocks 48 of the embedded straddle-type upper pressure roller 4 and the four upper connecting blocks 15 of the scissor-type lifting platform 1.
