One side of the upper end of the base is provided with a column, the other side of the upper end of the base is provided with a processing table, a sliding seat is fixed on the surface of the column, and a horizontal telescopic frame is fixed on the side of the sliding seat. By selecting the corresponding fixed clamping plate according to the size of the workpiece, the fixed clamping plate and the rotating seat are quickly fixed by a fixing pin, which is convenient for fixing parts of different sizes. Rotate the adjusting bolt to make the fixed clamping plate slide along the surface of the table board, and quickly clamp and fix the part by the fixed clamping plate; a horizontal telescopic frame is provided. The rotating motor rotates to drive the rotating lead screw to rotate, and the sliding seat fixed on the rotating lead screw slides along the slide rail, and the fixed cross beam at the upper end of the sliding seat slides horizontally. The telescopic frame is small in size, portable for transportation and use.

[0004] When the existing drill press is in use, a large amount of waste chips will be drilled during the operation of the drill bit. The waste chips are thrown out by the rotation of the drill bit and fall onto the workbench. When there is a lot of waste chip accumulation, the operator needs to clean it regularly, and the operation of cleaning the waste chips is inconvenient. Utility Model Content

[0005] In order to solve the problem of inconvenient manual cleaning of a large amount of waste chips accumulated on the workbench, the present application provides a drilling device for casting processing.

[0006] The drilling device for casting processing provided by the present application adopts the following technical solutions:

[0007] A drilling device for casting processing includes a frame and a box body. The frame is arranged on one side of the box body. A drilling machine is arranged on the frame and above the box body. A support table is arranged on the box body. A fixture for clamping the casting is arranged on the support table. A lower liquid outlet is arranged between the support table and the box body. A filter element is arranged below the support table in the box body. A collection box is slidably installed on one side of the filter element in the box body.

[0008] By adopting the above technical solution, the casting is placed at the support table, and the fixture clamps the casting. At this time, the drilling machine drills the casting, and the waste chips and lubricating fluid under the drilling fall into the inner side of the box through the lower liquid port. The filter element in the box filters and intercepts the waste chips, and collects them at the collection box on one side, separating and recycling the waste chips, eliminating the need for manual cleaning of the waste chips, and making the operation of cleaning the waste chips more convenient.

[0009] Optionally, the filter element includes a filter plate, the filter plate is inclined and arranged in the box, through filter holes are arranged on the filter plate, elastic members are arranged on the opposite sides of the filter plate in the box, and a knocking member is arranged on one side of the filter plate in the box.

[0010] By adopting the above technical solution, the knocking member knocks the filter plate, and the elastic member buffers the shaking of the filter plate, vibrating the waste chips remaining on the filter plate and dropping them to the collection box on one side for collection, reducing the probability of residual waste chips on the filter plate and reducing the frequency of manual cleaning of the filter plate.

[0011] Optionally, the knocking member includes a motor and an eccentric wheel. The motor is arranged outside the box, the eccentric wheel is eccentrically and rotatably installed on the inner side wall of the box, the eccentric wheel is connected to the output shaft of the motor, and one side of the eccentric wheel is attached to one side of the filter plate.

[0017] Optionally, a sliding groove is formed on the support table, and the first clamping plate and the second clamping plate are slidably mounted at the sliding groove of the support table.

[0018] By adopting the above technical solution, during adjustment, the first clamping plates and the second clamping plates on both sides slide along the sliding groove to limit the sliding directions of the first clamping plate and the second clamping plate.

[0019] Optionally, a surrounding plate is slidably mounted on the box body, the surrounding plate surrounds the box body on all sides, a driving cylinder is arranged outside the box body, and the surrounding plate is connected to one end of the piston rod of the driving cylinder.

[0020] By adopting the above technical solution, when it is necessary to drill the casting, the driving cylinder drives the surrounding plate to slide up, covering the surroundings of the casting, reducing the probability of waste chips flying out and falling outside the box body. When the drilling is completed, the driving cylinder drives the surrounding plate to slide down, facilitating the operator to remove the casting from the support table.

[0021] Optionally, a water outlet hole is arranged on the collection box on the side facing the filter plate.

[0022] By adopting the above technical solution, when collecting waste chips, part of the lubricating fluid falls onto the collection box along with the waste chips and flows into the box body through the water outlet hole, reducing the amount of lubricating fluid carried by the waste chips and facilitating the subsequent recovery of the lubricating fluid.
