Description

Technical Field

[0001] The present application relates to the technical field of wood processing, and in particular to a six-sided drilling spindle pressure plate device. Background Art

[0002] As an essential supporting equipment for the intelligent fully automatic production line used by large panel furniture manufacturers, the six-sided drill meets the requirements of multi-sided punching of panels. It can not only ensure the same precision of each hole position, but also improve processing efficiency, processing accuracy and product quality, and to a certain extent reduce the labor intensity of workers on the production site. With the rapid development of the custom furniture market, CNC six-sided drill can meet the various requirements of panel processing of many medium and large furniture manufacturers, and has gradually become an indispensable mainstream equipment for panel furniture processing.

[0003] Usually, the X-axis, Y-axis and Z-axis are set on the six-sided drilling equipment, and the Z-axis is used as the main axis of the six-sided drilling equipment. During the operation of the six-sided drilling equipment, the plate needs to be clamped in the main axis direction to perform machining operations such as milling grooves, drawing grooves and hole processing on the plate. In the market, the main axis pressure plate of CNC six-sided drilling is mostly made of HPL (High Pressure Laminate), which directly contacts the HPL with the furniture plate to clamp the plate in the main axis direction; or air floating pressure plate, which forms an air film between the furniture plate and the air nozzle to achieve the clamping of the plate in the main axis direction.

[0004] When HPL is used to clamp the sheet in the spindle direction, since HPL is in direct contact with the furniture sheet, in order to avoid uneven force on the furniture sheet, high requirements are placed on the flatness of HPL. If the HPL pressure is too high, the label on the furniture board will be scratched or directly scraped off, making it impossible to carry out subsequent work. If the HPL pressure is too low, the sheet cannot be clamped, which will cause large errors in the groove depth and hole depth of the sheet, and the sheet processing accuracy and quality cannot be guaranteed. The HPL pressure needs to be adjusted multiple times. When an air-floating pressure plate is used in the spindle direction, if the airflow is too large, there will also be the problem of blowing away the label; if the airflow is too small, the groove depth and hole depth added by the furniture board machine will have large errors, and the airflow size also needs to be adjusted multiple times to form an appropriate air film between the furniture sheet.

However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present application. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present application.

[0025] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. The singular forms of "a", "said" and "the" used in this disclosure and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0027] In the description of this application, unless otherwise specified and limited, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a mechanical connection or the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0028] In order to better understand the technical solution of the present application, the present application is described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-2 As shown, the present application provides a six-sided drilling spindle pressure plate device, including a spindle shield 1 and a driving mechanism 2, the output end of the driving mechanism 2 is connected to the spindle shield 1 to drive the spindle shield 1 to move in the spindle direction, the lower end of the spindle shield 1 is fixedly provided with a mounting plate 3, and a universal wheel assembly 4 is provided below the mounting plate 3, as shown in FIG. Figure 2 As shown, the mounting plate 3 is provided with a mounting hole 301, and the universal wheel assembly 4 includes a pressure wheel 401 and a mounting seat 402. The pressure wheel 401 is arranged below the mounting seat 402, and a mounting shaft 403 is fixedly arranged on the upper end of the mounting seat 402. The mounting seat 402 can rotate horizontally around the mounting shaft 403. The mounting shaft 403 is slidably connected to the mounting plate 3 through the mounting hole 301. A limiting member 405 is fixedly arranged at the position where the mounting shaft 403 passes through the mounting plate 3. The limiting member 405 is used to limit the downward moving distance of the mounting shaft 403, thereby preventing the universal wheel assembly 4 from falling off the mounting plate 3. An elastic element 404 is arranged between the mounting seat 402 and the mounting plate 3, and one end of the elastic element 404 is fixedly arranged on the mounting plate 3, and the other end of the elastic element 404 is fixedly arranged on the mounting seat 402.

[0030] In order to reduce the number of adjustments of the drive mechanism 2, the elastic element 404 always provides elastic force, the elastic element 404 is in a compressed state, and the compression amount is less than the maximum deformation of the elastic element 404. In this case, the pressure when the pressing wheel presses down the furniture board is the sum of the force provided by the drive mechanism and the elastic force of the elastic element, and the elastic force changes according to the deformation of the elastic element. Therefore, when the universal wheel assembly 4 contacts the furniture board, it can provide the furniture board with adaptive elastic force, reducing the number of adjustments to the drive mechanism. Figure 2 As shown, in this embodiment, the elastic element 404 is a spring, the spring is passed through the mounting shaft 403, one end of the spring is fixed to the lower surface of the mounting plate 3, and the other end of the spring is fixed to the upper surface of the mounting seat 402. The length of the spring in its natural state is 10 mm, the maximum deformation is 5 mm, and the elongation of the spring when the spring is installed is 7 mm.

[0031] In order to facilitate adjustment of the compression amount of the elastic element 404, the mounting shaft 403 in this embodiment is a stud, the diameter of the mounting shaft 403 is smaller than the diameter of the mounting hole 301, and the stopper 405 is a nut adapted to the mounting shaft 403, and the outer diameter of the nut is larger than the diameter of the mounting hole 301. The driving mechanism 2 can be a cylinder or a hydraulic cylinder. In this embodiment, the driving mechanism 2 is a cylinder disposed inside the spindle shield 1.

[0032] In order to make the furniture board bear force more evenly, a plurality of universal wheel assemblies 4 are symmetrically arranged below the mounting plate 3, such as Figure 2 As shown, four universal wheel assemblies 4 are arranged below the mounting plate 3, and four mounting holes 301 are arranged on the mounting plate 3. In this embodiment, the pressing wheel 401 is a rubber wheel to prevent the pressing wheel from scratching the surface of the furniture plate when the main shaft rotates.

[0033] An air blowing mechanism 5 is provided at one end of the mounting plate 3, and the air blowing mechanism 5 blows air toward the other end of the mounting plate 3. A dust suction mechanism 6 is provided at the other end of the mounting plate 3, and the dust suction port of the dust suction mechanism 6 faces the end of the mounting plate 3 where the air blowing mechanism is provided. After the furniture board is pressed in the main axis direction, when the six-sided drill performs various machining operations such as milling grooves, drawing grooves, and drilling holes on the furniture board, the air blowing mechanism 5 lifts up the wood chips and blows them to the vicinity of the dust suction port of the dust suction mechanism 6, and the dust suction mechanism 6 sucks away the wood chips to ensure that the processed furniture board is discharged cleanly and neatly.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present application, which should be included in the scope of the technical solution for protection in the present application.
