Description

Technical Field

[0001] The utility model belongs to the technical field of drilling machines, and in particular relates to a drilling machine with adjustable stroke. Background Art

[0002] A drilling machine is a machine tool that mainly uses a drill to make holes on a workpiece. Usually, the rotation of the drill is the main motion, and the axial movement of the drill is the feed motion. The drilling machine has a simple structure and relatively low processing accuracy. It can drill through holes and blind holes. By replacing special tools, it can expand, countersink, ream holes or perform tapping and other processing. During the processing, the workpiece does not move, and the tool moves to align the center of the tool with the center of the hole, and the tool rotates (main motion).

[0003] In the existing drilling machines with adjustable stroke, since the shapes of the workpieces to be processed are different, relying solely on a single square clamp to clamp the workpiece horizontally may result in loose clamping. In addition, during the drilling process, the workpiece may become loose because it is not firmly fixed, resulting in low drilling accuracy.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0026] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, 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.

[0027] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0028] See also Figure 1-Figure 6 As shown, the utility model is a drilling machine with adjustable stroke, comprising a base 1, a workbench 2 is fixedly installed in the middle of the base 1, a drilling rig 3 is fixedly installed on the top of the base 1, a mobile placement frame 4 is fixedly installed on the workbench 2, a power source 5 is fixedly installed at one end of the mobile placement frame 4, the power source 5 is fixedly installed on the workbench 2, a clamping member 6 is symmetrically slidably installed on the top of the mobile placement frame 4, a driving assembly 7 is threadedly installed between the two clamping members 6, and the driving assembly 7 is fixedly installed on the mobile placement frame 4.

[0029] When drilling, the workpiece is placed on the mobile placement rack 4 according to the shape of the workpiece to be processed. When the workpiece needs to be positioned, the driving component 7 will be driven first to drive the two symmetrically threaded clamping members 6 to move synchronously in the direction of the workpiece, and through the mutual rotation cooperation between the multiple internal rotating parts of the clamping member 6, the two parts closest to the workpiece can contact the irregular contour edge of the workpiece until the two parts closest to the workpiece are completely in contact with the two ends of the workpiece. At this time, the driving of the driving component 7 is stopped to allow the clamping members 6 to clamp and position the irregular workpiece. When it is necessary to correct the position of the clamped workpiece and the drill bit of the drilling rig 3, the driving power source 5 drives the fixedly installed mobile placement rack 4 to move. Since the workpiece is located on the mobile placement rack 4 at this time, the mobile placement rack 4 will then drive the workpiece to move until the workpiece moves to the position where a hole is desired to be drilled.

[0030] Therefore, when the workpiece needs to be positioned, the driving assembly 7 drives the two symmetrically threaded clamps 6 to move synchronously in the direction of the workpiece, thereby enabling the multiple internal rotating parts of the clamps 6 to rotate with each other, so that the two parts closest to the workpiece can contact and clamp the irregular contour edge of the workpiece to position it, thereby solving the problem of the workpiece loosening due to the workpiece not being firmly fixed, resulting in low drilling processing accuracy.

[0031] In one embodiment, for the above-mentioned base 1 , the base 1 includes a placement seat 101 , a fixing rod 102 is fixedly installed on the top of the placement seat 101 , and the other end of the fixing rod 102 is fixedly installed with the drilling rig 3 .

[0032] The placement seat 101 is used to support the entire device, and the fixing rod 102 is used to support the drilling rig 3 to ensure that the drilling rig 3 can work normally.

[0033] In one embodiment, for the above-mentioned mobile placement rack 4, the mobile placement rack 4 includes a placement plate 401, the placement plate 401 is slidably installed on the workbench 2, a plurality of anti-slip grooves 402 are opened on the placement plate 401, and rails 403 are symmetrically fixedly installed at both ends of the placement plate 401.

[0034] The power source 5 includes a telescopic rod 501 , which is fixedly mounted on the workbench 2 , and a power rod 502 is fixedly mounted on the output end of the telescopic rod 501 , and the other end of the power rod 502 is fixedly mounted on the placement plate 401 .

[0035] When it is necessary to correct the position of the clamped workpiece and the drill bit of the drilling machine 3, the telescopic rod 501 will be driven first to drive the fixedly installed power rod 502 to move, and then the power rod 502 will drive the placement plate 401 to move, and the irregular workpiece on the placement plate 401 will also move, and then the workpiece will move to the position where the hole is desired.

[0036] In one embodiment, for the above-mentioned clamping member 6, the clamping member 6 includes a fixed plate 601, and the fixed plate 601 is slidably installed on the track 403. A first rotating supporting plate 602 is rotatably installed inside the fixed plate 601, a second rotating supporting plate 603 is symmetrically rotatably installed inside the first rotating supporting plate 602, and a third rotating supporting plate 604 is symmetrically rotatably installed inside the second rotating supporting plate 603.

[0037] The driving assembly 7 includes a driving motor 701 , which is fixedly mounted on the track 403 . A threaded rod 702 is fixedly mounted on the output end of the driving motor, and the threaded rod 702 is threadedly mounted on the two fixing plates 601 .

[0038] The first rotating support plate 602 , the second rotating support plate 603 , and the third rotating support plate 604 are arranged in a semicircle.

[0039] When drilling, the workpiece is placed on the placement plate 401 according to the shape of the workpiece to be processed, and then the threaded rod 702 at the output end of the driving component 7 is driven to rotate, and then the threaded rod 702 will drive the two threaded fixed disks 601 to move, and then the fixed disk 601 will drive the first rotating support disk 602 to move, and then the first rotating support disk 602 will drive the second rotating support disk 603 to move, and then the second rotating support disk 603 will drive the third rotating support disk 604 to move. When the third rotating support disk 604 is moved, 04 When the irregular workpiece is moved out, the third rotating holding disk 604 will contact and fit the irregular workpiece by rotating inside the second rotating holding disk 603, and then the second rotating holding disk 603 will also rotate inside the first rotating holding disk 602, so that the third rotating holding disk 604 at both ends of the irregular workpiece can better contact the irregular workpiece. Therefore, through the rotation coordination of the first rotating holding disk 602, the second rotating holding disk 603 and the third rotating holding disk 604, the third rotating holding disk 604 can better clamp the irregular workpiece.

[0040] Thus, by driving the threaded rod 702 at the output end of the driving component 7 to rotate, the third rotating supporting disk 604 at both ends of the irregular workpiece is brought into contact with the irregular workpiece, so that the first rotating supporting disk 602, the second rotating supporting disk 603 and the third rotating supporting disk 604 are rotated in coordination, so that the third rotating supporting disk 604 can better clamp the irregular workpiece, thereby solving the problem of the workpiece loosening due to the workpiece not being firmly fixed, resulting in the problem of low drilling processing accuracy.
