Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing equipment technology, specifically relating to an automatic feed device for a grooving machine. Background Technology

[0002] A grooving machine is a specialized piece of equipment that creates grooves of a specific shape on the surface of a material through mechanical cutting or milling. It is widely used in construction, industry, transportation, and energy sectors. Using high-speed rotating cutters (such as diamond saw blades or carbide end mills) or hydraulically driven cutter blocks, it cuts grooves of preset width, depth, and shape into substrates such as roads, concrete walls, metal sheets, and wood.

[0003] Traditional grooving machines mostly employ manual or simple mechanical feed structures, which have the following technical drawbacks: low feed accuracy, reliance on operator experience, and difficulty in meeting high-precision machining requirements; insufficient automation, requiring frequent manual adjustments to the feed rate, leading to low processing efficiency; poor structural stability, prone to slippage and loosening under long-term high-intensity operation; and high maintenance costs, as traditional wedge-shaped guide rails are prone to wear and require regular replacement of parts. Furthermore, while some existing automatic feed devices utilize linear guide rails or rack and pinion structures, they suffer from high costs, weak vibration resistance, and low modularity. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic feed device for a grooving machine, comprising: a grooving tool assembly, which includes a tool motor, the output end of which is equipped with a grooving tool via a hydraulic sleeve; and an automatic feed device, wherein the grooving tool assembly is fixed to the automatic feed device via a longitudinal mounting base.

[0005] Preferably, the automatic feed device includes a longitudinal dovetail support plate, the bottom of which is mounted on the side wall of the grooving machine. A longitudinal ball screw assembly is mounted on the surface of the longitudinal dovetail support plate via a fixing plate. One end of the longitudinal ball screw assembly is connected to a servo motor via a planetary reducer.

[0006] Preferably, it also includes a longitudinal sliding seat, which is slidably mounted on the surface of the longitudinal ball screw assembly via a ball screw nut; one side of the bottom of the longitudinal sliding seat is provided with a dovetail groove that matches the shape of the side of the longitudinal dovetail support plate, and the other side of the bottom is fixed by a sealing plate and a limiting block.

[0007] Preferably, a transverse ball screw assembly is mounted on the top of the longitudinal sliding seat via the fixing plate, and one end of the transverse ball screw assembly is connected to the servo motor via the planetary reducer.

[0008] Preferably, it also includes a transverse support plate, the transverse support plate having an hourglass-shaped cross-section, which is slidably mounted on the surface of the transverse ball screw assembly via the ball screw nut; a dovetail groove matching the side shape of the transverse support plate is provided on one side of the top of the longitudinal sliding seat, and the limiting block is provided on the other side of the top.

[0009] Preferably, the longitudinal mounting base and the transverse support plate are fixed together by bolts.

[0010] The beneficial effects of this utility model are: The combined drive of the dovetail support plate and ball screw effectively improves the longitudinal and transverse feed accuracy, ensuring long-term stable machining accuracy. The self-locking of the dovetail groove effectively resists cutting vibration, and the hourglass-shaped transverse support plate, through stress dispersion design, effectively improves the structural stability during the feed process. The servo motor and PLC control realize automatic path planning, increasing machining efficiency by more than 3 times. Multiple processes can be completed in a single clamping, reducing manual intervention, lowering the labor intensity of operators, and significantly improving automation and machining efficiency.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] like Figures 1 to 3 As shown, this embodiment provides an automatic feed device for a grooving machine, including: a grooving tool assembly 1, which includes a tool motor 101, the output end of which is fitted with a grooving tool 103 via a hydraulic sleeve 102; and an automatic feed device 2, on which the grooving tool assembly 1 is fixed by a longitudinal mounting base 201. This embodiment aims to demonstrate the intelligent control, precision transmission, and mechanical self-locking effect of the automatic feed device 2 on the grooving tool assembly 1.

[0018] The automatic feed device 2 includes a longitudinal dovetail support plate 202, the bottom of which is mounted on the side wall of the grooving machine. A longitudinal ball screw assembly 204 is mounted on the surface of the longitudinal dovetail support plate 202 via a fixing plate 203. One end of the longitudinal ball screw assembly 204 is connected to a servo motor 206 via a planetary reducer 205. It also includes a longitudinal sliding seat 207, which is slidably mounted on the surface of the longitudinal ball screw assembly 204 via a ball screw nut 207-4. One side of the bottom of the longitudinal sliding seat 207 has a dovetail groove 207-1 that matches the shape of the side of the longitudinal dovetail support plate 202, and the other side of the bottom is fixed by a sealing plate 207-2 and a limiting block 207-3. The longitudinal dovetail support plate 202 and the longitudinal ball screw assembly 204 constitute a dual-guide precision transmission mechanism. The longitudinal dovetail support plate 202 and the dovetail groove 207-1 form a mechanical self-locking structure through a wedge-shaped contact surface, which can generate a locking torque of 300 N·m under the cutting vibration condition of the grooving tool assembly 1, preventing the sliding parts from moving in directions other than the specified direction. The ball screw assembly 204 converts the rotational motion of the servo motor 206 into linear motion, and together with the planetary reducer 205, achieves a feed resolution of 0.01 mm, effectively improving machining accuracy. The sealing plate 207-2 and the limiting block 207-3 make the contact surfaces of the longitudinal dovetail support plate 202 and the dovetail groove 207-1 fit more tightly, preventing iron filings from entering and affecting the smoothness of the longitudinal sliding seat 207 during movement.

[0019] A transverse ball screw assembly 208 is mounted on the top of the longitudinal sliding seat 207 via the fixing plate 203. One end of the transverse ball screw assembly 208 is connected to the servo motor 206 via the planetary reducer 205. A transverse support plate 209 is also included. The transverse support plate 209 has an hourglass-shaped cross-section and is slidably mounted on the surface of the transverse ball screw assembly 208 via the ball screw nut 207-4. A dovetail groove 207-1, matching the side shape of the transverse support plate 209, is provided on one side of the top of the longitudinal sliding seat 207, and a limiting block 207-3 is provided on the other side of the top. The longitudinal mounting seat 201 is fixed to the transverse support plate 209 with bolts. Since the transverse support plate 209 is directly mounted on its surface, the hourglass-shaped cross-section design of the transverse support plate 209 disperses the cutting reaction force throughout the entire support plate structure through a gradually changing cross-section, avoiding deformation caused by excessive local stress and effectively improving the stability of the structure during the feed process.

[0020] like Figure 3 The longitudinal sliding seat 207 shown is slightly wider than the transverse support plate 209 and the longitudinal dovetail support plate 202 when installed. The empty parts are all locked and limited by the limiting block 207-3. Therefore, the longitudinal sliding seat 207 in this application can be adapted to different sliders and sliding rails and has a wide range of applications.

[0021] In summary, the automatic feed device for the grooving machine in this embodiment achieves high-precision machining through a coordinated design of precision transmission and mechanical self-locking. The longitudinal dovetail support plate 202 and the ball screw form a dual-guide system, with a wedge-shaped contact surface creating a mechanical self-locking structure. Under cutting vibration, it can generate a locking torque of 300 N·m, which, combined with the ball screw transmission with a feed resolution of 0.01 mm, ensures longitudinal machining accuracy. The hourglass-shaped transverse support plate 209 adopts a variable cross-section design, distributing the cutting force throughout the entire structure and avoiding localized stress concentration. The longitudinal sliding seat 207 tightly engages with the dovetail support plate through the dovetail groove 207-1, and the sealing plate 207-2 and the limiting block 207-3 form a dustproof sealing system, ensuring smooth movement. The transverse support plate 209 achieves planar dual-degree-of-freedom constraint through secondary guidance of the dovetail groove 207-1. The servo motor 206 and PLC closed-loop control realize intelligent path planning, supporting continuous multi-process machining and effectively improving efficiency. Its modular design allows it to adapt to different tool components, making it widely applicable, especially suitable for high-precision composite grooving machining scenarios.
