Technical Field

[0001] The invention relates to the field of knife locking seats, in particular to a knife locking seat for a precision-carved knife handle with a double locking function. Background Art

[0002] The locking tool holder, also known as the tool remover, is a machine tool accessory used to lock the tool holder of CNC and machine tools for easy disassembly and replacement. The locking tool holder must meet the three requirements of not damaging the tool, easy disassembly and assembly, and stability. In actual use, the fine carving tool holder is usually placed on the locking tool holder with the corresponding shape and fixed by the narrow flat position on the tool holder. Then a needle bearing wrench is used to tighten it, so as to replace the grinding wheel and remove the tool holder from the locking tool holder. The currently used locking tool holder is generally composed of an iron base and an iron sheet. It has a simple structure and can be mass-produced.

[0003] Although the existing locking knife seat is simple in content, its service life is short, especially the life of the iron sheet. The iron sheet that has been changed in material, hardened with mold steel or other white steel is consumable and cannot withstand the daily replacement of thousands of knives on site; the locking knife seat of the existing technology is locked in place by a narrow flat position on the finely carved knife handle. Since the designer of the knife handle has designed the flat position to be only 2.2mm wide, the corresponding locking plate thickness cannot exceed its design specifications, which will cause the metal clamping plate surface to be too thin, resulting in easy wear and deformation, which in turn affects the efficiency of knife removal. Summary of the Invention

[0004] The purpose of the present invention is to provide a precision carving tool handle locking tool holder with a double locking function in order to solve the problems that the existing locking tool holder has a short service life and the locking plate surface is too thin, which leads to easy wear and deformation and affects the efficiency of tool removal.

DETAILED DESCRIPTION

[0027] To facilitate understanding of the invention, the invention will be described more fully below with reference to the accompanying drawings. The drawings illustrate exemplary embodiments of the invention. However, the invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive disclosure of the invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the invention pertains. The terms used in the specification of the invention herein are for the purpose of describing specific embodiments only and are not intended to limit the invention.

[0029] See also Figures 1 to 8 The carving knife handle locking knife seat with double locking function in the embodiment of the present invention includes a locking knife seat assembly 1, which includes a one-way seat 101, and a packaging plate 102 is respectively provided at the top and bottom ends of the one-way seat 101. The one-way seat 101 is fixedly connected to the two packaging plates 102 by screws 103. A plurality of grooves are opened inside the one-way seat 101, and rollers 104 are provided inside the grooves. A fixed seat assembly 2 is provided at the bottom end of the one-way seat 101, and the fixed seat assembly 2 includes an intermediate plate 201 threadedly connected to the bottom end of the one-way seat 101. The bottom end is fixedly connected to the vertical plate 202 by screws, and the bottom end of the vertical plate 202 is fixedly connected to the large base plate 203 by screws. The top of the large base plate 203 is provided with a cylinder tensioning assembly 3, and the cylinder tensioning assembly 3 includes: a cylinder 301 installed on the top of the large base plate 203, the cylinder 301 consists of a cylinder body and an output shaft slidably connected to the inner wall of the cylinder body, the top end of the cylinder body of the cylinder 301 is threadedly connected to a ball guide sleeve 302, the top end of the output shaft of the cylinder 301 is located inside the cylinder 301 and is threadedly connected to a ball guide rod 303, and the ball 304 is provided inside the ball guide rod 303.

[0030] In this embodiment, this device has amplified and imitated the locking tool holder sold on the market and the mechanical principle of the CNC equipment spindle grasping the tool handle, and transformed the original mechanical design of the flat position of the tool handle into a combination of the one-way bearing locking principle and the CNC precision carving tool handle locking form. The locking positions are respectively for the outer circle of the tool handle and the inner hole of the tool handle. The specific operation is: insert the tool handle into the one-way seat 101 and rotate it along the narrow direction of the slot. The rotation of the tool handle drives and squeezes the roller 104 into a smaller space. The state of the roller 104 will become the form of a wedge block, thereby locking the rotation of the tool handle, completing the The first locking; at the same time, align the groove at the bottom end of the knife handle with the ball guide rod 303 and insert it, and start the cylinder 301, use the downward pressure of the cylinder 301 to drive the ball guide rod 303 to move downward, and the ball guide rod 303 with the widened top end squeezes the ball 304 into the narrow and flat inner hole of the knife handle. The lateral pressure of the ball 304 and the downward component force implement the second locking. After double locking, the needle bearing wrench can be used for disassembly and assembly. The two locking mechanisms have the same function, so they can be used at the same time or disassembled and used separately. In addition, the roller 104 adopts a layered structure, and the double-layer design allows the knife handle to be disassembled and assembled here.

[0031] Please refer to Figures 2-4The grooves on the inner wall of the one-way seat 101 are narrow-mouthed and their number matches the number of rollers 104.

[0032] In this embodiment, the narrow-mouth groove allows the roller 104 placed therein to function as a wedge when it is pushed toward the narrow mouth to a limit, thereby locking the inserted tool handle.

[0033] Please refer to Figures 2-4 The slots opened by the one-way seat 101 are divided into two longitudinal layers, and the narrow openings of the two layers are in opposite directions.

[0034] In this embodiment, the one-way seat 101 is designed in layers with the narrow openings on both sides in opposite directions in order to enable the knife handle to be disassembled and assembled here. Specifically, the first layer prevents clockwise rotation and is used for locking the knife when the knife is installed, and the second layer prevents counterclockwise rotation and is used for locking the knife when the knife is removed.

[0035] Please refer to Figures 2-3 The packaging plate 102 is a ring-shaped structure, and the two packaging plates 102 are respectively arranged directly above and directly below the roller 104.

[0036] In this embodiment, the structure and location of the packaging plate 102 can effectively prevent the roller 104 from falling out of the one-way seat 101 .

[0037] Please refer to Figure 1 、 Figure 5 There are two vertical plates 202 and they are located on both sides of the bottom end of the middle plate 201 respectively. The height of the vertical plates 202 is greater than the height of the cylinder 301.

[0038] In this embodiment, the vertical plates 202 arranged on both sides increase the stability of the middle plate 201 installed on the top and the locking knife seat assembly 1. The height of the vertical plates 202 is greater than the height of the cylinder 301 to facilitate the installation of the cylinder tensioning assembly 3.

[0039] Please refer to Figure 1 、 Figure 4 The large base plate 203 is provided with screw mounting holes and open waist grooves around it.

[0040] In this embodiment, the holes and grooves provided around the large base plate 203 are provided for the user to install and fix on a workbench, so as to facilitate the use of the knife lock seat assembly 1 and the cylinder tensioning assembly 3 installed thereon in any installation scenario.

[0041] Please refer to Figures 6-8 The outer wall of the ball guide rod 303 is provided with curved grooves that match the number of balls 304, and the balls 304 are placed in the curved grooves.

[0042] In this embodiment, the special shape design of the curved notch can support the internal ball 304 to achieve the function of rolling obliquely upward and pressing the handle.

[0043] Please refer to Figures 6-8 The top of the ball guide sleeve 302 is provided with holes and slots that match the number of rollers 104. The holes and slots are designed to be tilted downward, and the opening position and size match the curved slots of the ball guide rod 303.

[0044] In this embodiment, the hole groove formed in the ball guide sleeve 302 is intended to accommodate the balls 304 that are squeezed out when the ball guide rod 303 moves downward. The hole groove is designed to be tilted downward so that when the ball guide rod 303 moves upward back to its original position, the balls 304 can automatically return to the curved groove of the ball guide rod 303 under the action of gravity.

[0045] Please refer to Figure 6 、 8 The inner diameter of the ball guide sleeve 302 and the outer diameter of the ball guide rod 303 both match the outer diameter of the output shaft of the cylinder 301 .

[0046] In this embodiment, the diameters of the three are matched, which not only facilitates the output shaft of the cylinder 301 to drive the ball guide rod 303 to move up and down, but also ensures the sealing performance of the cylinder 301.

[0047] Please refer to Figure 1 The cylinder tensioning assembly 3 is arranged directly below the one-way seat 101, and the connection between the cylinder 301 and the ball guide rod 303 is easy to disassemble, such as screw connection.

[0048] In this embodiment, the cylinder tensioning assembly 3 is located directly below the one-way seat 101, so that when the knife handle is inserted from above, it can simultaneously contact the roller 104 in the one-way seat 101 and the ball 304 in the ball guide rod 303, thereby achieving double locking; since the two locking assemblies have the same function, they can be used simultaneously or separately. The cylinder tensioning assembly 3 is easy to disassemble, and the two locking assemblies can be disassembled and used separately to increase the disassembly and assembly efficiency.

[0049] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
