Description

Technical Field

[0001] This utility model relates to the technical field of machining, and in particular to a grooving device for machine tool parts. Background Technology

[0002] Machine tool components refer to the various key components of a machine tool, including but not limited to the bed, worktable, slide, spindle, lead screw, and guide screw. During the production of machine tools, the spindle needs to be slotted.

[0003] In the prior art, patent document CN216325588U discloses a grooving device for machining mechanical shafts, including an operating table. An operating control panel is fixedly connected to the front end of the operating table, and an L-shaped bracket is fixedly connected to the rear end of the operating table. A drive groove is formed on the lower end of the L-shaped bracket, and a drive slider is slidably connected inside the drive groove. Four evenly distributed lifting cylinders are fixedly connected to the lower end of the drive slider. A grooving motor is fixedly connected to the output end of the four lifting cylinders, and a grooving cutter is fixedly connected to the output end of the grooving motor. A lifting concave groove is provided above the operating table. The device achieves the effect of fixing the mechanical shaft in all directions (front, back, left, and right). The adjusting screw drives the adjusting slider to move, facilitating the adjustment of the distance between the U-shaped bracket and the lifting concave groove, thus satisfying the need to fix mechanical shafts of different lengths. The device is easy to fix, has good performance, and prevents the mechanical shaft from shifting, improving the quality and efficiency of grooving the mechanical shaft.

[0004] During use, it was found that, such as Figure 7 As shown, the spindle is machined with four sets of slots at one end. The above device requires the operator to manually rotate the spindle, which requires high skill from the operator. The processing efficiency is low, the accuracy of the slot processing position is poor, and waste is easy to occur. The labor intensity of the operator is also high. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a grooving device for machine tool components.

[0006] This utility model discloses a grooving device for machine tool components, comprising a worktable and a controller. The controller is installed at the front end of the worktable. The device also includes a slide assembly, a positioning assembly, and a grooving assembly. The slide assembly is located at the top of the worktable, and the grooving assembly is mounted on the slide assembly. The slide assembly is used to adjust the left-right position of the grooving assembly, and the grooving assembly can be adjusted for front-back position on the slide assembly. The positioning assembly is used to position the spindle and allow it to rotate at equal angles. In use, the spindle is positioned for front-back position using the positioning assembly. Then, the grooving assembly is moved forward on the slide assembly, followed by moving the slide assembly to the left on the worktable, placing the grooving assembly in front of the spindle. The grooving assembly is then activated, and the controller operates the grooving assembly to slide backward on the slide assembly, thus machining a set of grooves on the outer wall of the spindle. After machining, the positioning assembly is used to rotate the spindle 90 degrees. This process is repeated to machine four sets of grooves on the spindle. No manual operation is required during the grooving process, reducing the labor intensity of workers, improving grooving accuracy, and increasing processing efficiency.

[0007] Preferably, the slide assembly includes a servo motor, a lead screw, a guide rod, a slide, a threaded connecting block, and a first slider. A groove is provided at the top of the worktable, in which the lead screw is rotatably mounted and the guide rod is fixedly mounted. A threaded connecting block and a first slider are provided at the bottom of the slide. The threaded connecting block is threadedly connected to the lead screw, and the first slider is slidably connected to the guide rod. A servo motor is mounted on the worktable, and its output end is connected to one end of the lead screw. The operator controls the rotation direction of the servo motor through a controller, thereby causing the lead screw, in cooperation with the guide rod, to drive the threaded connecting block, the first slider, and the slide to adjust their left and right positions, further realizing the adjustment of the slotted assembly's position and improving flexibility.

[0008] Preferably, the grooving assembly includes a fixed base, guide rods, a second slider, a housing, a milling cutter, and a first electric push rod. Two sets of guide rods are fixedly mounted on the top of the slide table via the fixed base. Two sets of second sliders are slidably mounted on each set of guide rods. The tops of all four sets of second sliders are connected to the bottom of the housing. A drive motor is installed inside the housing, and a milling cutter is detachably mounted on the output end of the drive motor. A first electric push rod is fixedly mounted on the top of the slide table, and the moving end of the first electric push rod is connected to the rear end of the housing. By extending the first electric push rod, the housing moves the milling cutter forward. When the slide table moves to the left, and the milling cutter is in front of the spindle, the drive motor is activated, causing the milling cutter to rotate rapidly. By shortening the first electric push rod, the housing moves backward with the cooperation of the second slider and the guide rod, allowing the rapidly rotating milling cutter to perform grooving on the fixed spindle, thus improving processing efficiency.

[0009] Preferably, the positioning assembly includes a first support, an electric chuck, a second support, a second electric push rod, a clamping block, and a conical head. The first support is located at the rear of the top of the worktable, and the electric chuck is mounted on the first support. The second support is located at the front of the top of the worktable, and the second electric push rod is fixedly mounted at its front end. A clamping block is located at the moving end of the rear of the second electric push rod, and a conical head is located at the rear end of the clamping block. The rear end of the spindle is clamped and fixed by the electric chuck. The second electric push rod is extended, causing the clamping block to clamp against the center of the front end of the spindle via the conical head. The conical head, in conjunction with the electric chuck, keeps the spindle balanced. After one set of slots is machined, the controller operates the electric chuck to rotate the spindle 90 degrees, allowing the grooving assembly to machine another set of slots on the spindle. The conical head keeps the spindle horizontal without interfering with the electric chuck's angle adjustment of the spindle.

[0010] Preferably, it also includes a collection box. The top of the slide table is provided with a placement groove, and the collection box is placed in the placement groove. When the milling cutter performs groove machining on the spindle, it generates chips. Since the collection box is directly below the spindle, the chips fall into the collection box under their own gravity. After machining is completed, the operator moves the collection box out of the placement groove to empty the chips, which improves convenience.

[0011] Preferably, the collection box also includes a handle; the collection box is provided with a handle, allowing staff to move the collection box using the handle, thus improving convenience.

[0012] Preferably, it also includes a handle cover, on which the handle is fitted; the operator grips the handle with the handle cover to reduce the occurrence of slippage.

[0013] Preferably, the worktable also includes adjustable feet, with a set of adjustable feet provided at each of the four corners of the bottom of the worktable; the four sets of adjustable feet work together to provide stable support for the worktable and improve the stability of the support.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the spindle is positioned back and forth by the positioning component. Then, the grooving component is moved forward on the slide assembly, and then the slide assembly is moved to the left on the worktable, so that the grooving component is in front of the spindle. The grooving component is started, and the controller is used to operate the grooving component to slide backward on the slide assembly, so that the grooving component processes a set of grooves on the outer wall of the spindle. After processing, the positioning component is operated to rotate the spindle 90 degrees. The above operation is repeated to process four sets of grooves on the spindle. During the grooving process, no manual operation is required, which reduces the labor intensity of the workers, improves the grooving accuracy, and improves the processing efficiency.
