Description

A head chamber mechanism for a manual milling head Technical Field

[0001] This utility model belongs to the field of milling machine technology, specifically, it relates to a head chamber mechanism for a manual milling head. Background Technology

[0002] In the field of machining, milling machines, as important metal cutting equipment, are widely used in industries such as mold manufacturing and parts processing. As the core component of a milling machine, the ease of installation and replacement, as well as its stability, directly affect machining efficiency and accuracy.

[0003] Existing manual milling head placement typically involves a simple bracket for holding the milling head. This placement mechanism is simple and low-cost. However, when the machine tool is running, it needs to be lifted out of the machine tool's range to avoid affecting processing. Because it needs to be lifted out of the processing area, it cannot provide a positioning function. Furthermore, time is required to determine the position of the milling head before installation.

[0004] To address the aforementioned problems, this application proposes a head chamber mechanism for a manual milling head. Summary of the Invention

[0005] In view of the problems in the related technologies, this utility model proposes a head chamber mechanism for a manual milling head to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A head magazine mechanism for a manual milling head includes a base, a machine head mounted on the top of the base, a head magazine mounted on the bottom of the machine head, a positioning seat fixedly mounted on the rear side of the base, a rotating arm rotatably connected to the positioning seat, and a mounting plate fixedly mounted on one end of the rotating arm.

[0008] The clamping mechanism includes a fixing ring, which is disposed on the top of the mounting plate. Multiple push rods are slidably connected to the fixing ring. A clamping plate is fixedly installed at one end of each push rod. The multiple clamping plates cooperate with each other and cooperate with the head compartment.

[0009] The cylinder is rotatably mounted on one side of the machine base, and the piston of the cylinder is rotatably connected to the rotating arm.

[0010] Preferably, the clamping mechanism further includes a tension spring, which is fixedly installed on one side of the clamping plate, and the other end of the tension spring is fixedly connected to the inner side of the fixing ring.

[0011] The tension spring allows the clamping plate to be pulled back to its original position, thus enabling the milling cutter to be disassembled.

[0012] Preferably, a hydraulic cylinder is fixedly installed at the bottom of the mounting plate, a base plate is fixedly installed on the piston of the hydraulic cylinder, and a plurality of support rods are fixedly installed at the top of the base plate, with the top ends of the support rods being fixedly connected to a fixing ring.

[0013] The piston of the hydraulic cylinder drives the base plate to rise and fall, thereby raising and lowering the milling cutter inside the fixing ring, which facilitates the stable placement and installation of the milling cutter.

[0014] Preferably, the bottom of the top rod is hinged to a tie rod, and the bottom ends of multiple tie rods are rotatably connected to the same pad.

[0015] The pad allows for easy placement of the milling cutter, and the pad and pull rod pull the push rod, causing the push rod to move in position. The clamping plate then holds and fixes the milling cutter in place.

[0016] Preferably, a backing plate is fixedly installed on one side of the base, and the backing plate cooperates with the rotating arm.

[0017] The support plate facilitates the positioning of the rotating arm, allowing it to be placed in a fixed position, thus enabling the accurate installation of the milling cutter inside the head chamber.

[0018] In summary, the technical effects and advantages of this utility model are as follows:

[0019] The articulated connection between the tie rod, the pad, and the top rod allows the milling cutter to be automatically clamped and fixed when placed on the pad. It can also position milling cutters of different sizes and, combined with the operation of the hydraulic cylinder, facilitates installation and disassembly.

[0020] The rotating arm is connected to the positioning seat, and the cylinder is connected to the rotating arm. With the action of the backing plate, the milling cutter on the mounting plate can be accurately installed, making it convenient for people to use. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Referring to Figures 1-5, a head chamber mechanism for a manual milling head includes a base 1, a head 2 mounted on the top of the base 1, a head chamber 10 mounted on the bottom of the head 2, a positioning seat 3 fixedly mounted on the rear side of the base 1, a rotating arm 4 rotatably connected to the positioning seat 3, and a mounting plate 5 fixedly mounted on one end of the rotating arm 4.

[0030] The clamping mechanism 6 includes a fixing ring 61, which is disposed on the top of the mounting plate 5. Multiple push rods 62 are slidably connected to the fixing ring 61. A clamping plate 63 is fixedly installed at one end of each push rod 62. The multiple clamping plates 63 cooperate with each other and cooperate with the head compartment 10.

[0031] Cylinder 11 is rotatably mounted on one side of the base 1, and the piston of cylinder 11 is rotatably connected to the rotating arm 4.

[0032] Referring to Figures 1 and 4, the clamping mechanism 6 also includes a tension spring 64, which is fixedly installed on one side of the clamping plate 63, and the other end of the tension spring 64 is fixedly connected to the inner side of the fixing ring 61. The bottom of the push rod 62 is hinged to a pull rod 66, and the bottom ends of multiple pull rods 66 are rotatably connected to the same pad 65. The pad 65 facilitates the placement of the milling cutter, and the push rod 62 is pulled by the pad 65 and the pull rod 66, causing the push rod 62 to move in position. The clamping plate 63 clamps and fixes the milling cutter. The tension spring 64 can pull the clamping plate 63 back to its original position, thereby disassembling the milling cutter.

[0033] Referring to Figure 4, a hydraulic cylinder 7 is fixedly installed at the bottom of the mounting plate 5. A base plate 8 is fixedly installed on the piston of the hydraulic cylinder 7. Multiple support rods 9 are fixedly installed on the top of the base plate 8. The top of the support rods 9 is fixedly connected to the fixing ring 61. The piston of the hydraulic cylinder 7 drives the base plate 8 to rise and fall, thereby raising and lowering the milling cutter inside the fixing ring 61, which facilitates the stable placement and installation of the milling cutter.

[0034] Referring to Figure 2, a backing plate 12 is fixedly installed on one side of the base 1. The backing plate 12 cooperates with the rotating arm 4. The backing plate 12 facilitates the positioning of the rotating arm 4, allowing the rotating arm 4 to be placed in a fixed position, thereby accurately installing the milling cutter in the head chamber 10.

[0035] Working principle: During operation, the milling cutter is placed inside the fixing ring 61, with its bottom end resting on the pad 65. The weight of the milling cutter presses the pad 65 downwards, causing it to move. The pad 65, via the pull rod 66, pulls the push rod 62, causing it to move and clamp the milling cutter in place via the clamping plate 63. The tension spring 64 allows the clamping plate 63 to be pulled back to its original position, thus allowing the milling cutter to be disassembled. When the milling cutter needs to be installed, the cylinder 11 switch is activated, and the piston of the cylinder 11 drives the rotating arm 4... By changing the angle, the milling cutter on the mounting plate 5 can be moved to a position below the head chamber 10. After the movement is completed, the hydraulic cylinder 7 pushes the base plate 8 upward, thereby moving the milling cutter in the fixing ring 61 into the head chamber 10. When the hydraulic cylinder 7 moves the base plate 8 downward, the pad 65 loses the pressure of the milling cutter, thereby releasing the fixing of the milling cutter and moving the fixing ring 61 downward. This facilitates the lateral movement of the mounting plate 5 and the fixing ring 61, thus facilitating the normal operation of the milling cutter.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
