Description

Technical Field

[0001] The utility model relates to the technical field of violin bow processing, in particular to a bow head pressing device. Background Art

[0002] A violin bow includes a bow stick, a tip, horsehair, a frog and other accessories. The bow head is located at the head of the violin bow, the tip of the bow stick, and one end of the horsehair is embedded in the mortise of the bow head with a small wooden plug. Since the horsehair is fixed in the bow head, whether the bow head is stably connected to the bow stick affects the quality of the violin bow.

[0016] The technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0017] The utility model provides an embodiment, as Figure 1As shown in the figure, a bow head pressing device includes a base 1, a pressing mechanism 2 fixed on the base 1, a lifting base 3 fixed on the base 1 and located below the pressing mechanism 2, a linear slide rail 4 arranged on one side of the pressing mechanism 2, a slide seat 5 arranged on the linear slide rail 4 and slidably matched with it, a tightening assembly 6 arranged on one side of the slide seat 5, and a clamping mechanism 7 fixed on the slide seat 5. In this embodiment, the pressing mechanism 2 is a hand press. A guiding groove matched with the linear slide rail 4 is arranged at the bottom of the slide seat 5. The tightening assembly 6 includes a tightening bolt passing through one side of the slide seat 5 and extending into the guiding groove. A receiving groove 301 located in the same vertical plane as the linear slide rail 4 is arranged at the top of the lifting base 3;

[0018] When performing the pressing work of the bow head and the bow rod, first place one end of the bow rod provided with the bow head in the receiving groove 301, and then clamp the other end of the bow rod through the clamping mechanism 7, which can improve the stability of the bow rod during the pressing process and ensure the quality of the violin bow after pressing;

[0019] Moreover, since the clamping mechanism 7 is arranged on the slide seat 5, the distance between the slide seat 5 and the pressing mechanism 2 is adjustable, which can adapt to the pressing work of bow rods with different lengths;

[0020] In order to adapt to the pressing work of bow rods with different models and widths, in a further embodiment, as Figure 2 shown, two adjusting seats 302 are slidably arranged in the receiving groove 301. A space for receiving the bow rod is formed between the two adjusting seats 302. A chute 303 perpendicular to the linear slide rail 4 is arranged at the bottom of the receiving groove 301. A slider 304 extending into the chute 303 is arranged at the bottom of the adjusting seat 302. A threaded through hole is arranged on the slider 304. The thread directions of the threaded through holes on the two sliders 304 are opposite. A first adjusting screw 305 rotatably connected to the lifting base 3 and threadedly engaged with the slider 304 is arranged in the chute 303. External threads with opposite spiral directions are arranged at both ends of the first adjusting screw 305, and the two external threads are respectively engaged with the threaded through holes of the two sliders 304;

[0021] Under the limiting action of the slider 304 and the chute 303, by rotating the first adjusting screw 305, the two adjusting seats 302 can be synchronously moved closer to each other or farther away from each other, which can adapt to bow rods with different widths;

[0022] In order to facilitate the bow rod to be installed in place, in a further embodiment, a vertical baffle 306 is arranged on one side of the receiving groove 301 away from the linear slide rail 4. When one end of the bow rod abuts against the baffle 306, the bow rod is installed in place, and at this time, the pressing mechanism 2 just corresponds to the position of the bow head;

[0023] Due to the difference in the positions of the bow heads on different bow rods, in order to facilitate adaptation to different bow rods, in a further embodiment, a first guiding hole 307 parallel to the linear slide rail 4 is provided on the lifting base 3. A guiding rod 308 is movably arranged in the first guiding hole 307 and is connected to the baffle 306. A threaded through hole is provided on the baffle 306 and is threadedly connected with a second adjusting screw rod 309. The second adjusting screw rod 309 is rotatably connected to the lifting base 3;

[0024] By rotating the second adjusting screw rod 309, the distance between the baffle 306 and the lifting base 3 can be changed;

[0025] During the process of the bow rod abutting against the baffle 306, in order to protect the bow rod, in a further embodiment, an elastic layer 310 is covered on the side wall of the baffle 306 close to the receiving groove 301;

[0026] Since some bow rods have a certain degree of curvature, in order to adapt to the pressing work of different bow rods and bow heads, in a further embodiment, a mounting seat 8 detachably connected to the base 1 is provided at the bottom of the lifting base 3. An installation groove 801 is provided inside the mounting seat 8 and a telescopic cylinder 802 is fixed. The telescopic rod of the telescopic cylinder 802 faces upward and is fixedly connected to the lifting base 3. A plurality of guiding columns 803 are provided on the mounting seat 8, and a second guiding hole cooperating with the guiding columns 803 is provided at the bottom of the lifting base 3.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
