Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and in particular to a vertical drilling bench. Background Technology

[0002] Bench drills are commonly used drilling equipment in machining and are widely used for drilling various parts. When drilling holes around a ring-shaped workpiece, due to the structural characteristics of the ring, traditional bench drills lack a dedicated support and fixing structure. During the drilling process, the ring is prone to deformation due to uneven stress, especially in the area around the hole, where deformation and displacement are very likely to occur, leading to reduced drilling accuracy and affecting the processing quality of the workpiece.

[0003] Therefore, it is necessary to invent a vertical drilling bench to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a vertical drilling bench to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vertical drilling bench, comprising a base, a drill body fixedly connected to the base, a worktable fixedly connected to the top of the drill body, an mounting plate mounted on the top of the worktable by bolts, a support plate provided on the top of the mounting plate, and a tensioning component provided on the side wall of the support plate.

[0006] The tensioning assembly includes a rectangular tube, which is rotatably connected to the side wall of the support plate via a bearing. A threaded rod is rotatably connected inside the rectangular tube, and a threaded block is threadedly connected to the outer wall of the threaded rod. Connecting blocks are fixedly connected to all four sides of the threaded block. A strip-shaped opening corresponding to the connecting block is opened on all four sides of the rectangular tube. A connecting rod is rotatably connected to the other end of the connecting block, and an arc-shaped tensioning plate is rotatably connected to the other end of the connecting rod.

[0007] The bottom of the arc-shaped support plate is provided with a support member, which also includes an outer cylinder. One end of the outer cylinder is fixedly connected to the side wall of the rectangular cylinder. An inner rod is slidably arranged inside the outer cylinder, and the other end of the inner rod is fixedly connected to the side wall of the arc-shaped support plate.

[0008] Preferably, the arc-shaped support plate has an arc-shaped guide groove on the side away from the support member.

[0009] Preferably, a fixing rod is fixedly connected to the top of the workbench, and a U-shaped baffle is rotatably connected to the outer wall of the fixing rod via a sleeve.

[0010] Preferably, the U-shaped baffle is made of transparent acrylic.

[0011] Preferably, a rotating disk is fixedly connected to the left end of the threaded rod.

[0012] Preferably, a motor is fixedly installed on the side wall of the support plate, and a first synchronous pulley is fixedly connected to the output end of the motor. A second synchronous pulley is fixedly connected to the outer wall of the rectangular tube, and a synchronous belt is connected between the second synchronous pulley and the first synchronous pulley. The motor drives the rectangular tube to rotate through the synchronous pulley and the synchronous belt, which in turn drives the annular frame to rotate. Drilling holes at different positions around the annular frame can be achieved without manual adjustment of the position of the annular frame, which is simple to operate and improves work efficiency.

[0013] The technical effects and advantages of this utility model are as follows: By setting up a support assembly, when drilling a hole in the annular frame, rotating the rotary disk drives the threaded rod to rotate, and the threaded block moves accordingly. Through the connecting block and connecting rod, the four arc-shaped support plates open or close synchronously, which can stably support annular frames of different sizes, avoid deformation of the annular frame and the drilling area during the drilling process, and improve the processing accuracy.

[0021] 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.

[0022] This utility model provides, for example Figure 1-6 The vertical drilling bench drill shown includes a base 1, a drill body 2 fixedly connected to the base 1, a worktable 3 fixedly connected to the top of the drill body 2, a mounting plate 4 bolted to the top of the worktable 3, a support plate 5 on the top of the mounting plate 4, and a tensioning assembly 6 on the side wall of the support plate 5.

[0023] The tensioning assembly 6 includes a rectangular tube 61, which is rotatably connected to the side wall of the support plate 5 via a bearing. A threaded rod 62 is rotatably connected inside the rectangular tube 61, and a threaded block 63 is threadedly connected to the outer wall of the threaded rod 62. Connecting blocks 64 are fixedly connected to all four sides of the threaded blocks 63. A strip-shaped opening corresponding to the connecting blocks 64 is opened on all four sides of the rectangular tube 61. A connecting rod 65 is rotatably connected to the other end of the connecting block 64, and an arc-shaped tensioning plate 66 is rotatably connected to the other end of the connecting rod 65. Four arc-shaped tensioning plates 66 are provided. When drilling holes around the annular frame, the four arc-shaped tensioning plates 66 can be used to support the annular frame around the annular frame, avoiding deformation of the annular frame or the area around the drilled holes during the drilling process.

[0024] The bottom of the arc-shaped support plate 66 is provided with a support member 67, which also includes an outer cylinder 671. One end of the outer cylinder 671 is fixedly connected to the side wall of the rectangular cylinder 61. An inner rod 672 is slidably provided inside the outer cylinder 671. The other end of the inner rod 672 is fixedly connected to the side wall of the arc-shaped support plate 66. The support member 67 can better support the position of the drill hole.

[0025] An arc-shaped guide groove 7 is provided on the side of the arc-shaped tensioning plate 66 away from the support member 67. The arc-shaped guide groove 7 can guide the debris generated by drilling, making it easy to collect and clean the debris. Moreover, the arc-shaped tensioning plate 66 will not be damaged when the drill bit drills through the annular frame.

[0026] A fixed rod 8 is fixedly connected to the top of the workbench 3. A U-shaped baffle 9 is rotatably connected to the outer wall of the fixed rod 8 via a sleeve. The U-shaped baffle 9 is made of transparent acrylic. The transparent acrylic material of the U-shaped baffle 9 can effectively block the flying of debris and ensure the safety of the operator, without affecting the observation of the processing process. At the same time, the U-shaped baffle 9 can rotate around the fixed rod 8 via the sleeve, which facilitates the picking and placing of workpieces.

[0027] A rotating disk 10 is fixedly connected to the left end of the threaded rod 62. By rotating the rotating disk 10, the threaded rod 62 can be driven to rotate.

[0028] A motor 11 is fixedly installed on the side wall of the support plate 5. The output end of the motor 11 is fixedly connected to a first synchronous pulley 12. A second synchronous pulley 13 is fixedly connected to the outer wall of the rectangular tube 61. A synchronous belt 14 is connected between the second synchronous pulley 13 and the first synchronous pulley 12. The position of the motor 11 can provide power for the rotation of the rectangular tube 61, thereby driving the annular frame to rotate and drilling holes in other positions around the annular frame.

[0029] The working principle of this utility model is as follows: When drilling the annular frame, the annular frame is placed on the outside of the four arc-shaped support plates 66. Rotating the rotating disk 10 drives the threaded rod 62 to rotate, and the threaded block 63 moves on the threaded rod 62. Through the connecting block 64 and the connecting rod 65, the four arc-shaped support plates 66 are pushed outwards synchronously until they are in close contact with the inner wall of the annular frame, achieving stable support for the annular frame. The inner rod 672 in the support member 67 slides inside the outer cylinder 671, providing auxiliary support for the arc-shaped support plates 66. The motor 11 is started, and the motor 11... The first synchronous pulley 12, the synchronous belt 14, and the second synchronous pulley 13 drive the rectangular cylinder 61 to rotate, thereby driving the annular frame to rotate. This allows drilling to be performed around the annular frame without the need for constant manual adjustment of its position, thus improving drilling efficiency. During drilling, the generated debris falls through the arc-shaped guide chute 7, and the U-shaped baffle 9 prevents debris from splashing. The operator can observe the processing through the transparent U-shaped baffle 9. After processing, the rotary disc 10 is rotated in the opposite direction to retract the arc-shaped support plate 66, allowing the processed annular frame to be removed.

[0030] 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.
