Description

Technical Field

[0001] This utility model relates to the field of drilling technology, specifically a drilling device for automobile mold processing. Background Technology

[0002] Automotive molds are specialized tools used in the automobile manufacturing process for the mass production of parts. Most automobile parts are manufactured using automotive molds.

[0003] Automotive molds have many mounting holes, which are drilled into the corresponding material using a drilling machine. Typically, when drilling a mold, the mold is lifted onto the drilling machine's platform using a hoisting mechanism. An operator then moves the mold on the platform to adjust its position, and the drill bit is positioned using the drilling machine's three-axis motion mechanism to drill the hole.

[0004] Although the hoisting mechanism can lift and move the mold, dragging the mold when its bottom contacts the machine will also cause wear and tear on the machine.

[0005] In view of this, we propose a drilling device for automotive mold processing. Utility Model Content

[0006] The purpose of this invention is to provide a drilling device for automobile mold processing to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a drilling device for processing automotive molds, comprising a drilling machine body, a worktable fixedly mounted on the frame of the drilling machine body, a movable plate mounted on the bottom of the worktable, and a plurality of rolling structures arranged on the upper surface of the movable plate, wherein the plurality of rolling structures are fitted with a plurality of through holes opened on the worktable.

[0008] The rolling structure includes a circular roller and fixed blocks. The two ends of the circular roller are respectively rotatably disposed in the grooves opened on the two fixed blocks. The two ends of the circular roller are respectively rotatably connected to the two fixed blocks through rotating shafts. The fixed blocks are fixedly disposed on the upper surface of the movable plate.

[0009] Preferably, the fixing block does not extend beyond the top of the through hole, and the circumferential surface of the roller contact side extends beyond the top of the through hole.

[0010] Preferably, the inner wall of the through hole does not contact the rotating shaft.

[0011] Preferably, the bottom of the groove is adapted to the circular roller.

[0012] Preferably, four pillars are fixedly arranged in a rectangular array on the bottom side of the workbench, and a hydraulic cylinder is fixedly installed in the groove of the pillar. Two connecting plates are symmetrically fixed on the bottom side of the movable plate, and the bottom sides of the two ends of the connecting plates are respectively fixedly connected to the outer ends of the piston rods of two hydraulic cylinders on the same side in the transverse direction.

[0013] Preferably, the end of the connecting plate passes through the groove on the support column, and the outer wall of the end of the connecting plate contacts and engages with the inner wall of the groove on the support column.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by setting up a worktable, a movable plate, a fixed block, a circular roller, a rotating shaft, and a groove, has the advantage that when the mold moves on the worktable, the rolling of the circular roller assists in the movement, and the mold will not drag along the upper surface of the worktable, causing wear on the worktable. It also solves the problem that dragging when the bottom of the mold contacts the machine tool will also cause wear on the machine tool.

[0016] 2.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1, please refer to Figure 1 , Figure 2 and Figure 5 An embodiment of this utility model provides a drilling device for processing automotive molds, including a drilling machine body 100. The power system of the drilling machine body 100 is mainly an electric motor, as well as a transmission mechanism, a drill bit clamping device, a feeding mechanism, a cooling and chip removal system, a frame and a base, and a control system. A worktable 200 is fixedly installed on the frame of the drilling machine body 100. A movable plate 500 is installed at the bottom of the worktable 200. Multiple rolling structures 700 are arranged on the upper surface of the movable plate 500. The multiple rolling structures 700 are connected and cooperate with multiple through holes 201 opened on the worktable 200.

[0028] The rolling structure 700 includes a circular roller 702 and fixed blocks 701. The two ends of the circular roller 702 are rotatably disposed within grooves 7011 formed in the two fixed blocks 701. The bottom of the grooves 7011 is adapted to the circular roller 702, and while the circular roller 702 rotates within the grooves 7011, the grooves 7011 also support the circular roller 702. The two ends of the circular roller 702 are rotatably connected to the two fixed blocks 701 via rotating shafts 703. The inner wall of the through hole 201 does not contact the rotating shaft 703, and the movement of the rotating shaft 703 is unaffected. The fixed blocks 701 are fixedly disposed on the upper surface of the movable plate 500. The fixed blocks 701 do not extend beyond the top of the through hole 201, and the contact side circumference of the circular roller 702 extends beyond the top of the through hole 201. Without affecting the rolling of the circular roller 702 in contact with the bottom of the mold, the fixed blocks 701 will not protrude from the through hole 201 and thus affect the movement of the mold.

[0029] The mold to be drilled is hoisted onto the worktable 200 by an external hoisting mechanism and moved. When the bottom of the mold contacts the protruding part of the roller 702, the roller 702 rolls accordingly as the mold is dragged to assist the movement of the mold and will not cause wear to the worktable 200.

[0030] This utility model, by setting up a worktable 200, a movable plate 500, a fixed block 701, a circular roller 702, a rotating shaft 703, and a groove 7011, has the advantage that when the mold moves on the worktable 200, the rolling of the circular roller 702 assists in its movement, and the mold will not drag along the upper surface of the worktable 200, causing wear to the worktable 200. It also solves the problem that dragging when the bottom of the mold contacts the machine tool will also cause wear to the machine tool.

[0031] Example 2, please refer to Figures 2 to 5 This utility model provides an embodiment of a drilling device for automotive mold processing. Four pillars 300 are fixedly arranged in a rectangular array on the bottom side of a worktable 200. Hydraulic cylinders 400 are fixedly installed in grooves on the pillars 300. The hydraulic cylinders 400 are selected and used by skilled personnel according to actual conditions. Two connecting plates 600 are symmetrically fixedly arranged on the bottom side of a movable plate 500. The bottom ends of the connecting plates 600 are respectively fixedly connected to the outer ends of the piston rods of the two hydraulic cylinders 400 on the same transverse side. The ends of the connecting plates 600 pass through grooves on the pillars 300, and the outer wall of the connecting plate 600 contacts and engages with the inner wall of the groove on the pillars 300. The hydraulic cylinders 400 can drive the connecting plates 600 to move longitudinally, causing the movable plate 500 to move up and down. After the mold is positioned, the movable plate 500 descends, causing the rolling structure 700 to descend, and the bottom of the mold contacts the worktable 200. The mold remains stable on the worktable 200 due to gravity.

[0032] This utility model, by setting up a support column 300, a hydraulic cylinder 400 and a connecting plate 600, has the advantage that after the mold is placed in the correct position, the movable plate 500 and the rolling structure 700 descend, causing the bottom of the mold to contact the worktable plate 200 and remain stable.

[0033] Working principle: When placing the mold, the movable plate 500 is in the state of being raised to the top. The mold to be drilled is hoisted onto the worktable 200 by the external hoisting mechanism and moved. When the bottom of the mold contacts the protruding part of the roller 702, the roller 702 rolls accordingly to assist the movement of the mold as the mold is dragged. After the mold is placed, the hydraulic cylinder 400 drives the connecting plate 600 to move down, and the movable plate 500 descends accordingly, causing the rolling structure 700 to descend. The roller 702 no longer contacts the bottom of the mold, and the mold remains stable on the worktable 200 due to gravity. The drilling machine body 100 drills holes in the mold.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
