Description

Technical Field

[0001] The utility model relates to the technical field of movement grinding, in particular to a small grinding tool for manufacturing watch movements. Background Art

[0002] During the manufacturing process of watch movements, grinding tools are needed to polish the surface of the movement, so as to improve the smoothness and beauty of the movement.

[0003] Existing grinding tools for movement generally include a grinding head and a clamping and mounting cylinder for mounting and fixing the movement. When grinding the movement, the movement is mounted on the top of the mounting cylinder, and the movement is clamped and fixed by clamping plates located at the top of the mounting cylinder close to each other, so that the top of the clamped movement is higher than the top of the clamping plate, thereby facilitating the contact between the grinding head and the top of the movement for grinding, and ensuring that the clamping plate can clamp the outer peripheral wall of the movement, so that the movement will not be separated when the mounting cylinder drives the movement to rotate.

[0004] After the movement is polished, multiple groups of clamping plates are slightly separated from each other, so that they are separated from the outer wall of the movement. Since the parts of the movement are small, the thickness of the movement after polishing is thin. External tools are needed to separate the polished movement from the middle of the clamping plates, which makes it inconvenient to remove the thin polished movement. In view of the shortcomings of the existing technology, we propose a small polishing tool for watch movement manufacturing to solve the above problems. Utility Model Content

[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] The embodiment of the utility model discloses a small grinding tool for manufacturing watch movements.

[0027] According to the attached Figure 1-5 Shown, including:

[0028] The clamping unit and the grinding head 2 located on one side of the clamping unit, the clamping unit includes a multi-assembly clamping cylinder 1, and the top end of the clamping cylinder 1 is provided with a clamping plate 101, which clamps the outer peripheral wall of the movement body 5.

[0029] The driving plate 3 is located at the bottom end of the multi-assembly chuck 1, and the multi-assembly chuck 1 is rotatably connected to the top end of the driving plate 3; before the movement body 5 is installed and polished, the top ends of the multiple groups of extension shafts 602 are higher than the top ends of the clamping plates 101. At this time, the multiple groups of movement bodies 5 are respectively limited to the top ends of the extension shafts 602, and the movement bodies 5 are fixed by magnets 605. Subsequently, the installed movement bodies 5 are driven downward by the driving cylinder 701 on one side, so that the support plate 601 at the bottom contacts the positioning plate 604, and the movement body 5 is located inside the clamping plate 101, and the movement body 5 is clamped and fixed by the multiple groups of clamping plates 101.

[0030] A support unit 6 is provided inside the clamping cylinder 1, and the support unit 6 includes a support plate 601 that is slidably connected. The top of the support plate 601 is installed with a core body 5, and the outer peripheral wall of the support plate 601 is engaged with the inner peripheral wall of the clamping cylinder 1. The rotation of the clamping cylinder 1 drives the internal support plate 601 to rotate. A driving unit 7 is provided on the outer wall of one side of the clamping cylinder 1, and a positioning plate 604 is fixedly connected to the inner bottom of the clamping cylinder 1. Then, the assembled clamping cylinder 1 is located directly below the grinding head 2. The rotation of the clamping cylinder 1 drives the internal support plate 601 to rotate together, so that the grinding head 2 at the top can grind the top of the core body 5.

[0031] The support plate 601 is driven to slide upward by the driving unit 7, so that the bottom end face of the movement body 5 is higher than the top end face of the clamping plate 101, and the bottom end face of the support plate 601 is fitted with the top end of the positioning plate 604, so that the top end face of the clamping plate 101 is in the middle position of the outer peripheral wall of the movement body 5. After polishing a group of movement bodies 5, the multi-assembly chuck 1 at the top is driven to make a circular motion by the driving plate 3 at the bottom, thereby achieving the purpose of polishing multiple groups of movement bodies 5.

[0032] The outer wall of the support plate 601 is provided with a tooth shape, and the inner wall of the clamping cylinder 1 is fixedly connected to the gear 603. The positioning plate 604 is located at the bottom end of the gear 603. The support plate 601 and the gear 603 are meshed with each other. The driving unit 7 includes a driving cylinder 701 installed on the outer wall of one side of the clamping cylinder 1. The output end of the driving cylinder 701 is fixedly connected to the mounting part 702. After polishing, multiple groups of clamping plates 101 move away from each other and no longer clamp the movement main body 5. By starting the driving cylinder 701 on one side, the mounting part 702 at the top drives the support plate 601 to slide on the inner wall of the clamping cylinder 1, so that the top extension shaft 602 can drive the polished movement main body 5 to completely detach from the interior of the clamping plate 101, so that the bottom end of the movement main body 5 is higher than the top end of the clamping plate 101, thereby facilitating the operation of removing the polished movement main body 5.

[0033] One end of the mounting member 702 passes through the inner wall of the clamping cylinder 1 and is fixedly connected to the outer wall of the support plate 601. An extension shaft 602 is fixedly installed on the top of the support plate 601. A magnet 605 is provided on the top end face of the extension shaft 602. The magnet 605 can adsorb and fix the movement body 5 after installation.

[0034] The movement body 5 is located at the top of the magnet 605, and the inner walls of multiple groups of clamping plates 101 are in contact with the outer peripheral walls of the movement body 5. A protective frame 4 is provided on the periphery of the driving plate 3, and the driving plate 3 is rotatably connected to the inner bottom of the protective frame 4. It should be noted that the outer peripheral wall of the support plate 601 and the inner peripheral wall of the clamping cylinder 1 are engaged with each other, so that when the clamping cylinder 1 rotates, the support plate 601 can drive the top movement body 5 to rotate together, thereby facilitating the grinding operation of the grinding head 2 on the movement body 5. At the same time, after grinding, under the action of the driving cylinder 701, the outer peripheral wall of the support plate 601 can slide upward along the teeth of the gear 603, so that the polished movement body 5 can be completely separated from the interior of the clamping plate 101, thereby facilitating the removal of the polished movement body 5.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
