Description

Technical Field

[0001] This utility model relates to the technical field of drill bit stabilizing mechanisms, and in particular to a drill bit stabilizing mechanism for a radial drilling machine. Background Technology

[0002] Supermarket shelves are composed of multiple alloy plates assembled with bolts. The multiple connecting holes on most alloy plates are drilled by a radial drilling machine. A radial drilling machine is a drilling machine in which the radial arm can rotate and rise around the column, and the spindle box usually moves horizontally on the radial arm. The radial drilling machine can be centered by moving the position of the tool axis, which brings great convenience to machining holes on large and heavy workpieces in single-piece and small-batch production.

[0003] However, in existing equipment, most radial drilling machines mount the drill bit on the drill bit sleeve by extrusion. But when drilling, if the extrusion force between the drill bit and the workpiece is too large, the drill bit is prone to slipping on the drill sleeve, resulting in low drilling quality. Therefore, a drill bit stabilizing mechanism for radial drilling machines is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drill bit stabilizing mechanism for radial drilling machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drill bit stabilizing mechanism for a radial drilling machine, comprising a base, a connecting column fixedly connected to the upper surface of the base, a rotating ring rotatably connected to the connecting column, a first toothed ring fixedly connected to the outer wall of the rotating ring, a movable column fixedly connected to one side of the rotating ring, a movable groove formed on one side of the movable column, a first threaded rod rotatably connected to the movable groove, a movable block threadedly connected to the first threaded rod, a spindle box fixedly connected to one side of the movable block, a drill bit sleeve rotatably connected to the bottom of the spindle box, three sliding grooves formed on the inner wall of the drill bit sleeve, a fixing structure provided on the drill bit sleeve, a first drill bit provided inside the drill bit sleeve, two fixing holes formed on the outer wall of the first drill bit, and two anti-slip structures provided on the drill bit sleeve.

[0006] As a further description of the above technical solution:

[0007] A first servo motor is fixedly connected to one side of the movable column, and the output shaft of the first servo motor is fixedly connected to one end of the first threaded rod.

[0008] As a further description of the above technical solution:

[0009] A fixing plate is fixedly connected to one side of the connecting column, and a second servo motor is fixedly connected to the upper surface of the fixing plate. A gear is fixedly connected to the output shaft of the second servo motor, and the gear meshes with the first gear ring.

[0010] As a further description of the above technical solution:

[0011] The fixed structure includes a rotating ring rotatably connected to the drill bit sleeve, and a conical toothed ring is fixedly connected to the upper surface of the rotating ring.

[0012] As a further description of the above technical solution:

[0013] The drill bit sleeve is rotatably connected to three second threaded rods, and each second threaded rod has a first conical tooth fixedly connected to one side. All three first conical teeth mesh with a conical tooth ring.

[0014] As a further description of the above technical solution:

[0015] One end of each of the three second threaded rods is rotatably connected to an extrusion column, and each extrusion column is slidably connected in a corresponding sliding groove.

[0016] As a further description of the above technical solution:

[0017] The anti-slip structure includes a fixed frame fixedly connected to the outer wall of the drill bit sleeve. A sliding rod is slidably connected through one side of the fixed frame. A locking pin is fixedly connected to one end of the sliding rod. One end of the locking pin is slidably connected through one side of the drill bit sleeve. The locking pin is adapted to a corresponding fixing hole. A spring is slidably provided on the sliding rod. One end of the spring is fixedly connected to the inner side of the fixed frame, and the other end is fixedly connected to one side of the locking pin.

[0018] As a further description of the above technical solution:

[0019] The upper surface of the fixed frame is provided with a threaded hole, and a compression rod is threaded into the threaded hole.

[0020] This utility model has the following beneficial effects:

[0021] 1. Compared with the prior art, the drill bit stabilizing mechanism for radial drilling machines is provided by setting a fixed frame, sliding rod, locking pin and spring, etc. Pulling the sliding rod causes the locking pin to move and compress the spring. Then the first drill bit is placed in the drill bit sleeve. Then the sliding rod is released, and the locking pin is locked into the fixed hole under the elasticity of the spring. This avoids the first drill bit slipping on the drill bit sleeve due to excessive squeezing force between it and the workpiece, which would affect the drilling quality of the first drill bit.

[0022] 2. Compared with the prior art, the drill bit stabilizing mechanism for radial drilling machines, by setting threaded holes and extrusion rods, rotates the extrusion rod so that the bottom of the extrusion rod presses against the sliding rod, thereby fixing the sliding rod and reducing the probability that the locking pin will disengage from the fixing hole due to centrifugal force when the drill bit sleeve drives the first drill bit to rotate.

Detailed Implementation

[0034] 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.

[0035] Reference Figures 1 to 9 This utility model provides a drill bit stabilizing mechanism for a radial drilling machine, comprising a base 1, a connecting column 2 fixedly connected to the upper surface of the base 1, a rotating ring 3 rotatably connected to the connecting column 2, a first toothed ring 4 fixedly connected to the outer wall of the rotating ring 3, a fixing plate 13 fixedly connected to one side of the connecting column 2, a second servo motor 14 fixedly connected to the upper surface of the fixing plate 13, a gear 15 fixedly connected to the output shaft of the second servo motor 14, the gear 15 meshing with the first toothed ring 4, and a moving column 5 fixedly connected to one side of the rotating ring 3, with a moving groove on one side of the moving column 5 for moving... A first threaded rod 6 is rotatably connected inside the groove. A first servo motor 7 is fixedly connected to one side of the moving column 5. The output shaft of the first servo motor 7 is fixedly connected to one end of the first threaded rod 6. A moving block is threadedly connected to the first threaded rod 6. A spindle box 8 is fixedly connected to one side of the moving block. A drill bit sleeve 9 is rotatably connected to the bottom of the spindle box 8. Three sliding grooves 901 are opened on the inner wall of the drill bit sleeve 9. A fixing structure 10 is provided on the drill bit sleeve 9. A first drill bit 12 is provided inside the drill bit sleeve 9. Two fixing holes are opened on the outer wall of the first drill bit 12. Two anti-slip structures 11 are provided on the drill bit sleeve 9.

[0036] To achieve the purpose of fixation, the fixing structure 10 includes a rotating ring 101 rotatably connected to the drill bit sleeve 9. A conical toothed ring 102 is fixedly connected to the upper surface of the rotating ring 101. Three second threaded rods 103 are rotatably connected to the drill bit sleeve 9. A first conical tooth 104 is fixedly connected to one side of each second threaded rod 103. All three first conical teeth 104 mesh with the conical toothed ring 102. One end of each of the three second threaded rods 103 is rotatably connected to a pressing post 105. Each pressing post 105 is slidably connected in a corresponding sliding groove 901. Rotating the rotating ring 101 causes the conical toothed ring 102 to rotate, which in turn causes the three first conical teeth 104 to rotate. The three first conical teeth 104 cause the corresponding second threaded rods 103 to rotate, and each second threaded rod 103 causes the corresponding pressing post 105 to move. The three pressing posts 105 press against the first drill bit 12, quickly fixing the first drill bit 12 and improving the fixing efficiency.

[0037] To achieve anti-slip properties, the anti-slip structure 11 includes a fixed frame 111 fixedly connected to the outer wall of the drill bit sleeve 9. A sliding rod 112 is slidably connected through one side of the fixed frame 111. A locking post 113 is fixedly connected to one end of the sliding rod 112. One end of the locking post 113 is slidably connected through one side of the drill bit sleeve 9. The locking post 113 is adapted to the corresponding fixed hole. A spring 114 is slidably mounted on the sliding rod 112. One end of the spring 114 is fixedly connected to the inner side of the fixed frame 111, and the other end is fixedly connected to one side of the locking post 113. Pulling the sliding rod 112 causes the locking post 113 to move and compress the spring 114. Then, the first drill bit 12 is placed inside the drill bit sleeve 9. Then, the sliding rod 112 is released. Under the elasticity of the spring 114, the locking post 113 is locked into the fixed hole, preventing the first drill bit 12 from slipping on the drill bit sleeve 9 due to excessive squeezing force between it and the workpiece, thus affecting the drilling quality of the first drill bit 12.

[0038] In order to reduce the likelihood of the snap-fit ​​post 113 disengaging from the fixing hole, a threaded hole 115 is provided on the upper surface of the fixing frame 111. A pressing rod 116 is threaded into the threaded hole 115. Rotating the pressing rod 116 causes the bottom of the pressing rod 116 to press against the sliding rod 112, thereby fixing the sliding rod 112 and reducing the probability that the snap-fit ​​post 113 will disengage from the fixing hole due to centrifugal force when the drill bit sleeve 9 drives the first drill bit 12 to rotate.

[0039] Working principle: Pulling the sliding rod 112 causes the locking pin 113 to move and compress the spring 114. Then, the first drill bit 12 is placed inside the drill bit sleeve 9. Releasing the sliding rod 112 allows the locking pin 113 to engage with the fixing hole under the elasticity of the spring 114, preventing the first drill bit 12 from slipping against the drill bit sleeve 9 due to excessive pressure between it and the workpiece, thus affecting the drilling quality. Then, rotating the pressing rod 116 causes its bottom to press against the sliding rod 112, fixing the sliding rod 112 and lowering its position. When the low drill bit sleeve 9 drives the first drill bit 12 to rotate, the centrifugal force may cause the locking post 113 to disengage from the fixing hole. Then, the rotating ring 101 rotates, which drives the conical toothed ring 102 to rotate. The conical toothed ring 102 drives the three first conical teeth 104 to rotate, and the three first conical teeth 104 drive the corresponding second threaded rods 103 to rotate. Each second threaded rod 103 drives the corresponding pressing post 105 to move. The three pressing posts 105 press against the first drill bit 12, which quickly fixes the first drill bit 12 and helps to improve the fixing efficiency.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
