[0002] Drilling and tapping equipment generally refers to mechanical equipment used for drilling, tapping and other machining operations on workpieces. This type of equipment is widely used in industries such as machinery manufacturing, mold manufacturing, and automotive parts production, and is an important tool for achieving high-precision hole machining and thread machining.

[0003] The existing method of clamping the workpiece results in a fixed clamping angle, which makes it difficult to adjust the workpiece clamping angle according to the actual required drilling angle. This method is not very practical. Furthermore, during the drilling process using drilling equipment, the workpiece is usually pressed and fixed from top to bottom using a clamp. However, when the clamping angle of the workpiece changes, the stability of the pressing and fixing method is poor, which makes it easy for the workpiece to deviate during drilling.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example

[0022] Please see Figure 1 A tiltable workpiece clamping and drilling device includes a base 1, an angle adjustment mechanism 9 on the top of the base 1, a platform 2 fixedly connected to the top of the angle adjustment mechanism 9, a side clamping mechanism 3 for clamping and fixing the side of the workpiece fixedly installed at the top center of the platform 2, a fixing frame 4 fixedly installed at the middle of the rear side of the base 1, a hydraulic cylinder 6 fixedly installed at the top of the fixing frame 4, an installation plate 7 fixedly installed at the output end of the hydraulic cylinder 6, a drill table 5 on the installation plate 7, and a top pressing mechanism 8 fixedly installed at the bottom of the installation plate 7.

[0023] In use, the base 1 is used to fix the angle adjustment mechanism 9, the angle adjustment mechanism 9 is used to adjust the angle of the clamped workpiece, the platform 2 is used to support the workpiece, the side clamping mechanism 3 is used to clamp and fix the side of the workpiece, and the top pressing mechanism 8 is used to press and fix the workpiece from top to bottom.

[0024] Please see Figure 1 and Figure 3The side clamping mechanism 3 includes a fixed box 31 fixedly connected to the center of the top of the platform 2. The fixed box 31 has three limiting grooves 32 evenly distributed around its top. The center of the bottom surface inside the fixed box 31 is rotatably connected to an installation shaft 38. A gear 39 is fixedly installed on the top of the installation shaft 38. Three claws 33 are engaged on the top of the gear 39, and the claws 33 are slidably connected inside the limiting grooves 32. The top of the claws 33 moves through the top of the fixed box 31. A ring tooth 37 is fixedly installed at the bottom edge of the gear 39. A rotating shaft 35 rotates through the outside of the fixed box 31. A square hole 34 is opened at the center of the end of the rotating shaft 35, and a spur gear 36 that meshes with the ring tooth 37 is fixedly sleeved at the end of the rotating shaft 35 away from the square hole 34.

[0025] During use, the side clamping mechanism 3 first places the workpiece to be clamped at the top center of the fixed box 31. Then, the square shaft handle is inserted into the square hole 34 on the rotating shaft 35. The handle is then rotated, which drives the rotating shaft 35 and the spur gear 36 on it. Then, the ring gear 37 and the gear plate 39 on it are rotated in sync. At the same time, multiple jaws 33 move along the limiting groove 32 toward the center of the fixed box 31, thereby using the jaws 33 to clamp and fix the side of the workpiece.

[0026] See Figure 1 and Figure 2 The angle adjustment mechanism 9 includes a servo motor 91 fixedly connected to the top right side of the base 1. A lead screw 94 is fixedly connected to the output end of the servo motor 91. A second fixing block is rotatably connected to the left end of the lead screw 94. The second fixing block is fixedly installed on the top left side of the base 1. A movable block 92 is threadedly connected to the lead screw 94 through a ball nut. A connecting rod 95 is hinged to the top of the movable block 92. A fixed head 90 is rotatably connected to the end of the connecting rod 95 away from the movable block 92. The top of the fixed head 90 is fixedly connected to the bottom left side of the platform 2.

[0027] See Figure 1 and Figure 2 The top of the base 1 has four fixed plates 96 in a rectangular shape. The four fixed plates 96 are arranged in pairs and are symmetrically distributed front and back. The two fixed plates 96 in the same group are fixedly connected to a guide rod 93. The guide rod 93 is slidably connected to a limit block. Both limit blocks are fixedly connected to the movable block 92. The bottom left side of the platform 2 has two connecting blocks 98 fixedly connected in a symmetrical manner. The two connecting blocks 98 are rotatably connected to a fixed rod 99. The front and rear ends of the fixed rod 99 are respectively fixedly installed with a fixed plate 97. The fixed plate 97 is fixedly installed on the top of the base 1.

[0028] When the angle adjustment mechanism 9 is in use, after the side clamping mechanism 3 stably clamps the side of the workpiece, the angle of the workpiece is adjusted according to the required drilling angle. The servo motor 91 is started, and the output end of the servo motor 91 drives the lead screw 94 to rotate, which synchronously drives the movable block 92 to move along the direction of the second guide rod 93 towards the third fixed plate 97. At the same time, it drives the bottom of the connecting rod 95 to move towards the third fixed plate 97, which in turn drives the stage 2 to rotate around the axis of the fixed rod 99. Simultaneously, it drives the stage 2 and the side clamping mechanism 3 on it to rotate around the axis of the fixed rod 99, thereby realizing the angle adjustment of the workpiece on the side clamping mechanism 3 until the appropriate angle is adjusted.

[0029] See Figure 1 , Figure 4 and Figure 5 The top pressing mechanism 8 includes two fixed arms 87 that are symmetrically fixed to the drill platform 5. The bottom of the two fixed arms 87 away from the drill platform 5 is fixedly connected to a fixed sleeve 85. A first guide rod 81 slides through the inside of the fixed sleeve 85. The top of the first guide rod 81 slides through the top of the fixed arm 87 and is fixedly sleeved with a stop block 84. A spring 86 is fixedly connected inside the fixed sleeve 85 and is wound around the outside of the first guide rod 81. A first fixing block 82 is fixedly connected to the bottom of the first guide rod 81. A rubber pad 83 is fixedly installed at the bottom of the first fixing block 82. The spring 86 is located on the top surface inside the first fixing block 82 and the fixed sleeve 85.

[0030] Once the workpiece angle is adjusted to the appropriate position, hydraulic cylinder 6 is activated. The output end of hydraulic cylinder 6 drives mounting plate 7 and its top pressing mechanism 8 downward until rubber pad 83 first contacts the top of the workpiece. Then, it drives the first fixing block 82 and its first guide rod 81 upward, compressing spring 86. The elastic force of spring 86 presses rubber pad 83 onto the top of the workpiece, achieving top pressing and fixing of the workpiece and improving the stability of the workpiece during drilling. After top pressing and fixing, drill table 5 is activated, and the drill bit in drill table 5 rotates at high speed to drill the workpiece. After drilling is completed, the pressing of the top pressing mechanism 8 and the clamping of the side clamping mechanism 3 are released, and a new workpiece is placed in. The above steps are repeated for processing.

[0031] It should be noted that, in the use of this tiltable workpiece clamping and drilling device, the workpiece to be clamped and fixed is first placed at the top center of the side clamping mechanism 3. The side clamping mechanism 3 is used to clamp and fix the workpiece from the side. After clamping and fixing, the angle adjustment mechanism 9 is used to adjust the angle between the side clamping mechanism 3 and the workpiece on it. After adjusting to a suitable angle, the drill table 5 is started to realize the high-speed rotation of the drill bit. At this time, the output end of the hydraulic cylinder 6 drives the mounting plate 7 to move downward, and simultaneously drives the top pressing mechanism 8 and the drill table 5 to move downward. The top pressing mechanism 8 is used to press and fix the workpiece clamped by the side clamping mechanism 3 from top to bottom, thus realizing the stability of the workpiece.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
