[0002] In the field of machining, rhomboid grooving cutters are commonly used cutting tools, and their machining quality has a significant impact on the machining accuracy of subsequent workpieces. During the manufacturing process of rhomboid grooving cutters, holes need to be drilled in the cutter to secure it to the tool holder. However, due to the unique external shape of the rhomboid grooving cutter, traditional rectangular clamping blocks cannot provide sufficiently stable clamping force. During the drilling process, if the rhomboid grooving cutter moves, it will not only cause deviations in the drilling position, affecting the compatibility of the cutter and tool holder, but may also lead to problems such as hole diameter errors and rough hole walls, severely reducing the machining accuracy and product quality of the grooving cutter, increasing the scrap rate and production costs. Furthermore, traditional machining devices also have certain shortcomings in terms of operational convenience and processing efficiency, failing to meet the ever-increasing production demands. Therefore, there is an urgent need for a grooving cutter drilling device that can effectively solve the above problems. Utility Model Content

[0015] The following is a description of the embodiments and appendices. Figures 1-3 The technical solution of this utility model will be further described below.

[0016] Example 1

[0017] A grooving and drilling device includes a bench drill 1 and an adjustable platform 2. The bench drill 1 includes a base 11, a column 12, an upper cover 13, a motor 14, a spindle box 15, a drill bit 16, and a handwheel assembly 17. The column 12 is fixed to the upper end of the base 11, providing a stable support foundation for the entire bench drill and ensuring stability during the machining process. The upper cover 13 is fixed to the upper end of the column 12 to protect the internal components such as the motor 14 and the spindle box 15, preventing dust and debris from entering and affecting the operation of the equipment. The motor 14 and the spindle box 15 are mounted on the upper cover 13. The motor 14 serves as a power source, connecting to a stepped pulley 141 via an output shaft, and then driving a stepped pulley 152 in the spindle box 15 via a belt 142 to rotate, thereby transmitting power and driving the spindle box 15 to work. The drill bit 16 is located at the lower end of the spindle box 15 and performs rotary cutting under the drive of the spindle box 15. The handwheel assembly 17 includes a handwheel 171 and a pinion 172. The handwheel 171 is rotatably connected to the upper cover 13. When the operator rotates the handwheel 171, it drives the pinion 172 to rotate. The pinion 172 meshes with the tooth groove on the outside of the guide sleeve 153, thereby controlling the guide sleeve 153. Since the long shaft 155 is connected to the inner ring of the bearing inside the guide sleeve 153, the lifting and lowering of the long shaft 155 and the main shaft 151 are controlled, ultimately achieving precise control of the lifting and lowering of the drill bit 16, which allows the operator to adjust the position of the drill bit according to processing requirements.

[0018] The adjustable platform 2 includes a worktable 21, a fixed V-shaped seat 22, a sliding V-shaped seat 23, and a cylinder 24. The worktable 21 is mounted on the column 12, providing a working plane for machining operations. The fixed V-shaped seat 22 is fixed to the left side of the upper end of the worktable 21, and the sliding V-shaped seat 23 is connected to the left output end of the cylinder 24. The cylinder 24 is fixed to the right side of the upper end of the worktable 21. The use of the V-shaped seat to clamp the rhomboid groove cutter is based on the characteristics of the V-shaped structure. The V-groove can fit tightly against the side of the rhomboid groove cutter, providing a larger contact area and more uniform clamping force compared to traditional rectangular clamping blocks, effectively preventing the rhomboid groove cutter from moving during machining. When clamping the groove cutter is required, the cylinder 24 operates, pushing the sliding V-shaped seat 23 to move to the left, cooperating with the fixed V-shaped seat 22 to stably clamp the rhomboid groove cutter between them, ensuring that the groove cutter remains in a fixed position during drilling and improving drilling accuracy. The worktable 21 is provided with chip removal holes 215, which allow the chips generated during drilling to be smoothly discharged, preventing chips from accumulating on the worktable and affecting the machining operation and machining accuracy.

[0019] As a further preferred embodiment, the upper end of the worktable 21 is provided with an extension plate 211, and the middle of the extension plate 211 is provided with a guide sleeve 212. The guide sleeve 212 is concentrically arranged with the drill bit 16 and the chip removal hole 25. The guide sleeve 212 provides precise guidance for the descent of the drill bit 16. In traditional drilling, the drill bit may deviate during descent due to factors such as cutting forces, resulting in inaccurate drilling position. However, the guide sleeve 212, being concentric with the drill bit 16, can limit the radial movement of the drill bit 16, ensuring that the drill bit always descends along the predetermined central axis, thereby guaranteeing the perpendicularity and positional accuracy of the drilling, and further improving the machining quality of the grooving cutter.

[0020] As a further preferred embodiment, a positioning slide 26 is fixed on the worktable 21, and the sliding V-shaped seat 23 is slidably disposed within the slide groove 261 of the positioning slide 26. The function of the positioning slide 25 is to provide a precise sliding track for the sliding V-shaped seat 23, ensuring that the sliding V-shaped seat 23 can slide stably along a straight line under the drive of the cylinder 24.

[0021] As a further preferred embodiment, a sliding sleeve 213 is fixed to the left side of the worktable 21. The sliding sleeve 213 is slidably fitted onto the column 12. A clamp 214 is provided on the outside of the sliding sleeve 213, which fixes the worktable 21 to the column 12. This allows the height of the worktable 21 to be flexibly adjusted according to actual processing needs. When processing diamond-shaped groove cutters of different specifications or thicknesses, the operator can release the clamp 214, move the sliding sleeve 213 up and down to adjust the worktable 21 to a suitable height, and then fix the worktable 21 to the column 12 using the clamp 214.

[0022] As a further preferred embodiment, the output shaft of the motor 14 is connected to a stepped pulley 141. The spindle box 15 includes a spindle 151, a stepped pulley 152, a guide sleeve 153, a chuck 154, and a long shaft 155. The upper end of the long shaft 155 is connected to the stepped pulley 152. A bearing is provided inside the guide sleeve 153. The long shaft 155 is connected to the inner ring of the bearing. The lower end of the long shaft 155 is connected to the spindle 151. The chuck 154 is connected to the lower end of the spindle 151. The drill bit 16 is disposed in the chuck 154. The handwheel assembly 17 includes a handwheel 171 and a pinion 172. The handwheel 171 is rotatably connected to the upper cover 13. The pinion 172 is fixedly connected to one side of the handwheel 171. The pinion 172 is meshed with the tooth groove outside the guide sleeve 153. The stepped pulley 141 and the stepped pulley 152 are connected by a belt 142. This transmission structure design, through different combinations of the diameters of stepped pulley 141 and stepped pulley 152, can achieve different speed ratios from the motor 14 to the spindle 151, meeting the speed requirements of the drill bit 16 under different machining conditions. For example, when machining diamond-shaped grooves made of harder materials, a larger speed ratio can be selected to increase the speed of the drill bit 16 and enhance cutting ability; when machining parts requiring high precision, a smaller speed ratio can be selected to reduce the speed of the drill bit 16 and ensure machining accuracy. Simultaneously, the cooperation between the handwheel assembly 17 and the guide sleeve 153 enables precise manual control of the raising and lowering of the spindle 151, allowing the operator to adjust the position of the drill bit 16 at any time according to the machining situation, improving the flexibility and controllability of the machining process.

[0023] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
