[0004] In view of this, the purpose of the present invention is to provide a bench drill structure with an adjustable workbench to achieve the purpose of improving production quality.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a bench drill structure with an adjustable workbench, including a main machine, a support column, a support seat and a workbench, the support column is fixed on the main machine, the support seat is slidably connected to the support column along the length direction of the support column, the support seat is connected to the support column through a locking structure, the workbench is connected to the support seat, the side of the workbench facing away from the main machine is fixedly connected to a slide seat, a slide rod is slidably connected to the slide seat, a support rod is fixedly connected to the slide seat, a support rod is rotatably connected to the support seat, and a positioning bolt is threadedly connected to the slide seat for pressing against the slide rod.

[0006] To implement the above technical solution, a pulling force is applied to the support rod, and the slide rod moves along its own length direction, so that the support rod can be moved away from the workbench. Then the positioning bolt is rotated to make the positioning bolt and the slide rod press tightly. The friction force generated can fix the slide rod. Under the joint action of the support rod and the workbench, it has a good supporting effect on larger parts, which facilitates drilling and achieves the purpose of improving production quality.

[0007] As a preferred solution of the present invention, the outer wall of the support column is fixedly connected to a rack along its own length direction, and the support seat is rotatably connected to a first gear and a second gear, the first gear is engaged with the second gear, and the second gear is engaged with the rack, and the first gear is fixedly connected to a handle rotatably connected to the support seat.

[0008] To implement the above technical solution, the handle is rotated, the handle drives the first gear to rotate, the first gear drives the second gear to rotate, and the second gear can drive the support seat to move along the length direction of the rack, thereby facilitating the adjustment of the position of the support seat and easy operation.

[0009] As a preferred solution of the present invention, the locking structure includes a locking groove, a first connecting part, a second connecting part and a locking bolt. The locking groove is opened on the support seat and connects the inner wall and outer wall of the support seat. The first connecting part and the second connecting part are fixed on the support seat and are respectively located on both sides of the locking groove. The locking bolt is rotatably connected to the first connecting part and is threadedly connected to the second connecting part.

[0010] To implement the above technical solution, the locking bolt is rotated to cause the second connecting portion to move closer to the first connecting portion, thereby reducing the width of the locking groove and enabling the support seat to clamp the support column to fix the support seat.

The two ends of the elastic member are respectively connected to the inner wall of the mounting hole and the limiting rod. The limiting hole is opened on the extension member. The retaining ring is fixed on the inner wall of the limiting hole. A part of the limiting rod extends from the mounting hole and is embedded in the limiting hole and then conflicts with the retaining ring.

[0016] To implement the above technical solution, the limit rod is pressed into the mounting hole. At this time, the extension piece can rotate along the axis of the connecting shaft to adjust the flipping angle of the workbench. When the limit rod corresponds to another limit hole, the elastic force of the elastic piece causes a part of the limit rod to penetrate into the limit hole and contact with the retaining ring. At this time, the inner wall of the mounting hole contacts the limit rod, and at the same time, the inner wall of the limit hole contacts the limit rod, so that the extension piece cannot rotate along the connecting shaft, so that the workbench can be fixed after flipping to a certain angle.

[0017] As a preferred solution of the present invention, a connecting hole is provided on the extension piece, a push rod is slidably connected in the connecting hole, and a resistance section is fixedly connected to the end of the push rod. When the push rod collides with the retaining ring, the resistance section passes through the retaining ring and pushes the limit rod into the mounting hole.

[0018] To implement the above technical solution, pressure is applied to the push rod, and the push rod contacts the retaining ring. At the same time, the contact section passes through the retaining ring and pushes the limit rod into the installation hole, thereby facilitating the rotation of the extension piece.

[0020] To implement the above technical solution, the vertical rod is moved along its own length direction so that the position of the baffle corresponds to the drill bit. The vertical rod is positioned by the friction between the vertical rod and the vertical tube. The debris generated during the drilling process can be blocked by the baffle to enhance the protection of workers. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0028] A bench drill structure with an adjustable workbench 85 includes a main unit 1, a support column 11, a support base 2, and a workbench 85. The support column 11 is fixed to the main unit 1 and placed vertically. The support base 2 is slidably connected to the support column 11 along its length. The support base 2 is connected to the support column 11 via a locking structure 3.

[0029] The locking structure 3 includes a locking groove 31, a first connecting portion 32, a second connecting portion 33, and a locking bolt 34. The locking groove 31 is defined in the support base 2 and connects the inner and outer walls of the support base 2. The first and second connecting portions 32, 33 are fixed to the support base 2, with the first and second connecting portions 32, 33 located on either side of the locking groove 31. The locking bolt 34 is rotatably connected to the first connecting portion 32 and threadedly engaged with the second connecting portion 33.

[0030] Tighten the locking bolt 34 to move the second connection portion 33 toward the first connection portion 32 , so that the support base 2 can clamp the support column 11 , and the generated friction force can fix the support base 2 .

[0031] The support seat 2 is rotatably connected to the extension member 4 via a connecting shaft 41, and the connecting shaft 41 is horizontally arranged. The support seat 2 and the extension member 4 are connected via a limiting structure 5. The limiting structure 5 includes a mounting hole 51, a limiting rod 52, an elastic member 53, a limiting hole 54, and a retaining ring 55. A plurality of mounting holes 51 are opened on the support seat 2 and are evenly distributed along the axis of the connecting shaft 41, and the axis of the mounting hole 51 is horizontally arranged. The limiting rod 52 is slidably connected to the mounting hole 51. The elastic member 53 is a spring, and the two ends of the elastic member 53 are respectively connected to the inner wall of the mounting hole 51 and the limiting rod 52, and an elastic force is applied to the limiting rod 52, so that the limiting rod 52 continues to have a tendency to extend from the mounting hole 51.

[0032] A stopper hole 54 is formed in the extension member 4 and is coaxial with the mounting hole 51 and has the same diameter. A retaining ring 55 is fixed to the inner wall of the stopper hole 54 and is coaxial with the stopper hole 54. A portion of the stopper rod 52 extends from the mounting hole 51 and is inserted into the stopper hole 54, where it contacts the retaining ring 55.

[0033] A connecting hole 61 is provided on the extension member 4 and is coaxially arranged with the limiting hole 54. A push rod 62 is slidably connected in the connecting hole 61, and an abutment section 63 is fixedly connected to the end of the push rod 62.

[0034] When the push rod 62 contacts the retaining ring 55, the contact section 63 passes through the retaining ring 55 and pushes the limiting rod 52 into the mounting hole 51. Furthermore, the end surface of the contact section 63 is flush with the end surface of the extension member 4, and the end surface of the limiting rod 52 is flush with the end surface of the support base 2, thereby allowing the extension member 4 to rotate along the axis of the connecting shaft 41. When the push rod 62 is released and the limiting rod 52 is aligned with the other limiting hole 54, the limiting rod 52 is inserted into the limiting hole 54, thereby securing the extension member 4.

[0035] A rotation hole 71 is formed at one end of the extension member 4 away from the connecting shaft 41. The axis of the rotation hole 71 is perpendicular to the axis of the connecting shaft 41. An adjustment tube 72 is rotatably connected in the rotation hole 71. The extension member 4 is connected to the adjustment tube 72 via a fixing structure 8.

[0036] The fixing structure 8 includes a fixing bolt 81, a fixing slot 82, a first fixing portion 83, and a second fixing portion 84. The fixing slot 82 is formed on the extension member 4 and communicates with the rotation hole 71. The first fixing portion 83 and the second fixing portion 84 are fixedly connected to the extension member 4. The fixing bolt 81 is rotatably connected to the first fixing portion 83 and is threadedly connected to the second fixing portion 84.

[0037] When the fixing bolt 81 is rotated, the second fixing portion 84 moves toward the first fixing portion 83 , so that the extending member 4 clamps the adjusting tube 72 .

[0038] The adjusting tube 72 is fixedly connected to the workbench 85 .

[0039] Accordingly, the workbench 85 can rotate along the axis of the adjustment tube 72. At the same time, the workbench 85 can rotate along the axis of the connecting shaft 41, so that the rotation angle and flipping angle of the workbench 85 can be adjusted to adapt to parts of different shapes and improve practicality.

[0040] Two slides 86 are fixedly connected to the side of the workbench 85 facing away from the main machine 1. Slide rods 87 are slidably connected to the slides 86, and the slide rods 87 move along the width of the workbench 85. Positioning bolts 871 are threadedly connected to the slides 86 for tightening against the slide rods 87. Supports 88 are fixedly connected to the ends of the slide rods 87, and a support rod 89 is rotatably connected to the support 88.

[0041] A rack 94 is fixedly connected to the outer wall of the support column 11 along its length. A first gear 95 and a second gear 96 are rotatably connected to the support base 2. The first gear 95 meshes with the second gear 96, and the second gear 96 meshes with the rack 94. A handle 97 is fixedly connected to the first gear 95 and rotatably connected to the support base 2.

[0042] A vertical pipe 91 is fixedly connected to the side wall of the main machine 1, and a vertical rod 92 is rotatably connected inside the vertical pipe 91. A baffle 93 is fixedly connected to the vertical rod 92, and the baffle 93 surrounds the drill bit.

[0043] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
