[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment, this embodiment provides a CNC milling machine processing table that is convenient for cleaning milling debris, including a table top 1, on which a plurality of T-shaped support blocks are provided, such as Figure 1 and Figure 2 As shown, the workpiece is fixed to the support block on the table 1 by using the milling machine clamping head and the fixture for milling. The table 1 is provided with a hollow hole located between two adjacent support blocks, and the hollow hole serves as a channel for cleaning the milling debris generated after milling from the table 1 to the bottom of the table 1.

[0026] It also includes a cleaning piece, which includes a gantry 2 that can be adjusted laterally back and forth on the support block and a cleaning sheet 21. The two sides of the table top 1 are bent downward to form a support portion, and two screw rods 24 are rotatably arranged between the two support portions. The two bottom ends of the gantry 2 are provided with sleeves 23 that are respectively threadedly sleeved with the two screw rods 24, such as Figure 4 As shown, a motor for providing power to the screw rod 24 is arranged on the outer wall of the support part. The screw rod 24 rotates to drive the sleeve 23 to adjust the position reciprocatingly along the axial direction of the screw rod 24, thereby driving the gantry 2 to adjust the position reciprocatingly in the horizontal direction. A transmission rod 27 for providing rotational power is arranged between the two side walls of the inner top of the gantry 2. A motor for providing rotational power to the transmission rod 27 is arranged on the side of the gantry 2. The cleaning sheet 21 is fixedly arranged along the radial side wall of the transmission rod 27, as shown in FIG. Figure 3 As shown, the transmission rod 27 can drive the cleaning sheet 21 to perform a circular motion with the transmission rod 27 as the rotation center.

[0027] The end of the cleaning sheet 21 is provided with a deformable portion. When the cleaning sheet 21 rotates and passes through the support block, the vertical height of the cleaning sheet 21 is greater than the vertical gap between the transmission rod 27 and the support block, and the deformable portion will bend and deform, so that it can rotate and pass through the top wall of the support block directly below the transmission rod 27. In this process, the deformable portion is in soft contact with the top wall of the support block. After the deformable portion contacts the top wall of the support block, it bends and deforms to expand the contact surface with the top wall of the support block, thereby expanding the cleaning surface.

[0028] The space between the top wall of the gantry 2, the side wall of the shielding part and the upper side wall of the support block forms a shielding space. The inner side wall of the shielding space blocks debris from splashing. A shielding part perpendicular to the support block is provided at the top of the side wall of the gantry 2. The shielding part is located on one side of the shielding space. A plurality of guide blocks 26 are provided on the side wall. The side walls of the guide blocks 26 extend obliquely to the side away from the shielding part to form a V-shaped structure. Figure 4 and Figure 5 As shown, after the milling is completed, the gantry 2 is moved horizontally on the support block, and while moving, the cleaning sheet 21 is driven by the transmission rod 27 to perform unidirectional rotation. When the deformation part rotates through the support block, the milling debris remaining on the support block will be swept into the shielding space. The milling debris is swept by the deformation part and flies to the multiple guide blocks 26 on the side wall of the shielding part. The milling debris is dispersed along the V-shaped side wall of the guide block 26 to the position opposite to the hollow hole between two adjacent support blocks, and falls from the hollow hole position, replacing manpower to achieve the cleaning of the table 1.

[0029] like Figure 3 As shown, the cleaning sheet 21 adopts the plastic rubber ring that can be woven or woven, has softness, and when the cleaning sheet 21 rotates through the support block top wall, it is convenient to bend and deform.In the cleaning sheet 21, there are multiple reinforcing rods 25 that are fixedly connected with the side walls of the transmission rod 27, and the length of the reinforcing rod 25 and the vertical height sum of the deformation portion are equal to the cleaning sheet 21 vertical heights, which is also a requirement, the cleaning sheet 21 is except the part of the deformation portion, and the rest part is supported by the reinforcing rod 25, and the situation of bending and deformation will not occur, such a benefit is, it can be ensured that the cleaning sheet 21 can follow the transmission rod 27 to rotate synchronously, and it will not be relatively soft because of the cleaning sheet 21, causing the transmission rod 27 to rotate initially, and the cleaning sheet 21 and the transmission rod 27 rotate and there is a speed difference, and the cleaning sheet 21 is wound on the transmission rod 27 outer wall, affects the deformation portion and effectively contacts with the support portion top wall, and performs cleaning operation.Simultaneously, the deformation portion is not restricted by the reinforcing rod 25, so that when the deformation portion rotates through the support block top wall, the bending and deformation situation occurs, so that it is easy to rotate smoothly across the support block top wall, and realizes the cleaning operation.

[0030] At the same time, the guide block 26 needs to be located between two adjacent hollow holes, so that the two inclined side walls of the guide block 26 can be used to divert the milling debris to the position above the hollow hole, and the milling debris can smoothly fall into the hollow hole, so that the milling debris can be cleaned from the support block. At the same time, the bottom wall of the guide block 26 is slidably fitted with the top wall of the support block, and the bottom wall of the guide block 26 is used to slide along the top wall of the support block, so that the two inclined side walls of the guide block 26 can be used to further clean the milling debris located on the top wall of the support block into the hollow hole.

[0031] Furthermore, a plurality of inverted T-shaped push blocks 22 are provided on the bottom wall of the shielding portion. The push blocks 22 are slidably engaged with the side walls of two adjacent support blocks. The push blocks 22 move synchronously with the gantry 2. The push blocks 22 can scrape off the milling chips attached to the opposite side walls of the two adjacent support blocks.

[0032] After the debris on the table 1 is cleaned, the gantry 2 is adjusted in the reverse direction and reset to the side of the table 1 to prevent the entire cleaning unit from occupying too much space on the table 1 and affecting subsequent milling operations. Figure 6 As shown, the upper end surface of the collecting drawer 3 is an open structure for receiving the milling chips falling from the hollow hole. The milling chips falling from the hollow hole to the bottom of the table 1 fall into the collecting drawer 3. After the collecting drawer 3 is full, the collecting drawer 3 is pulled out horizontally from the position between the two supporting parts to facilitate the disposal of the milling chips in the collecting drawer 3.

[0033] A rolling guide wheel is provided on the bottom wall of the collection drawer 3, and the rolling guide wheel is utilized to facilitate horizontal sliding and pulling of the collection drawer 3.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
