Description

Technical Field

[0001] This utility model relates to the field of grooving machine technology, and more specifically, to a grooving machine that facilitates adjustment of the tool holder position. Background Technology

[0002] Grooving machines, also known as grooving milling machines, can be divided into various types depending on the application scenario. For example, grooving machines used for grooving materials such as wood and metal sheets are widely used in furniture manufacturing, decoration, and other woodworking, leather, and rubber industries.

[0003] In the processing of stainless steel sheets, grooving machines use cutting tools to cut the surface of the sheet, creating designated grooves. When machining grooves of different depths, the tool holder needs to be disassembled and new tools installed, making this adjustment method extremely inconvenient and lacking in operability. Therefore, we propose a grooving machine with an easily adjustable tool holder position. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a grooving machine that is easy to adjust the position of the tool holder, so as to solve the technical problems of inconvenient tool adjustment and poor operability.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a grooving machine that facilitates the adjustment of the tool holder position, comprising a tool holder box and a stabilizing shaft. The tool holder box is installed on the side of the bottom base of the adjusting frame. The adjusting frame is connected to the base via a hydraulic rod. A protective frame is fixed at the lower opening of the tool holder box. Both ends of the tool holder box are rotatably mounted with drive shafts, and the drive shafts are connected by two drive belts. A handle frame is installed equidistantly between the two drive belts. A tool handle is slidably inserted into the inner side of the handle frame. A grooving tool is installed at the lower end of the tool handle, and the grooving tool is located inside the protective frame. The stabilizing shaft is installed through the tool holder box.

[0006] When in use, this utility model is powered by an external power source. The operator starts the device through an external control device, which activates the drive shaft connected to the motor to rotate it. The drive shaft drives the drive belt to rotate, and the drive belt, through the engagement of the insert shaft and the bushing, completes the deflection and tilting of the handle frame. When the handle frame deflects, the bushing slides in the adjustment groove to achieve automatic balance. The handle frame maintains its center of gravity through the rotation on the stabilizing shaft. At this time, the handle frame drives the tool handle to deflect, and the grooving tool at the lower end of the tool handle tilts. By the above operation, the tilt angle of the grooving tool is changed. The larger the tilt angle, the shallower the grooving depth. This device adjusts the grooving depth of the grooving tool through electric adjustment, eliminating the need for disassembly and replacement, thus reducing the difficulty of operation. The center of the adjustment mechanism of this device is the stabilizing shaft. When disassembling, pull out the stabilizing shaft to separate it from the positioning hole on the tool holder box, tool handle, and handle frame. At this time, the tool handle can be slid out to complete the disassembly, reducing the difficulty of operation and the difficulty of later maintenance through convenient disassembly.

[0007] Preferably, the upper and lower ends of both sides of the handle frame are provided with adjustment grooves, and a bushing is slidably installed in the adjustment groove. A plug shaft is rotatably installed in the outer end opening of the bushing.

[0008] Preferably, the outer end of the insert shaft is inserted and fixed to the corresponding side of the corresponding transmission belt.

[0009] Preferably, positioning holes are provided at equal intervals on both sides of the tool holder box, and positioning holes are provided on both sides of the handle frame and in the middle of the tool handle.

[0010] Preferably, the stabilizing shaft passes through the corresponding positioning holes in the tool holder box, the tool holder, and the shank frame.

[0011] Preferably, the length of the handle frame is adapted to the spacing between the upper and lower sides of the transmission belt.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model designs a handle frame, which is driven by a motor connected to the start-up drive shaft. The drive shaft drives the drive belt to rotate, and the drive belt, through the cooperation of the insert shaft and the bushing, completes the deflection and tilting of the handle frame. When the handle frame deflects, the bushing slides in the adjustment groove to achieve automatic balance. The handle frame maintains its own center of gravity by rotating on the stabilizing shaft. At this time, the handle frame drives the tool holder to deflect, and the grooving cutter at the lower end of the tool holder tilts. By changing the tilt angle of the grooving cutter through the above operation, the greater the tilt angle, the shallower the grooving depth. This device completes the adjustment of the grooving depth of the grooving cutter through electric adjustment, without the need for disassembly and replacement, reducing the difficulty of operation.

[0014] 2. This utility model also features a stabilizing shaft. The center of the adjustment mechanism of this device is the stabilizing shaft. When disassembling, the stabilizing shaft is pulled outward to separate it from the positioning holes on the tool holder box, tool handle, and handle frame. At this time, the tool handle can be slid out to complete the disassembly, reducing the difficulty of operation and reducing the difficulty of later maintenance through convenient disassembly.

[0024] Working Principle: This embodiment provides a grooving machine with an easily adjustable tool holder position. During use, it is powered by an external power source. The operator starts the device via an external control device, activating the drive shaft 401 connected to a motor that rotates it. The drive shaft 401 drives the drive belt 402. The drive belt 402, through the insertion shaft 409 and the bushing 407, completes the deflection and tilting of the handle frame 404. When the handle frame 404 deflects, the bushing 407 slides within the adjusting groove 408 to achieve automatic balance. The handle frame 404 is stabilized by the rotation on the stabilizing shaft 405. The device moves to maintain its center of gravity. At this time, the handle frame 404 drives the tool handle 403 to deflect, and the grooving cutter 406 at the lower end of the tool handle 403 tilts. By changing the tilt angle of the grooving cutter 406 through the above operation, the greater the tilt angle, the shallower the grooving depth. The center of the adjustment mechanism of this device is the stabilizing shaft 405. When disassembling, pull out the stabilizing shaft 405 to separate the stabilizing shaft 405 from the positioning hole 410 on the tool holder box 4, the tool handle 403 and the handle frame 404. At this time, the tool handle 403 can be slid out to complete the disassembly.
