Problems solved by technology

[0005] In order to overcome the need to continuously pull the tool by hand to slot the hexagonal qin tube, the operation is cumbersome, and people can only slot one side of the hexagonal qin tube at a time, resulting in low work efficiency. The technology of the present invention The problem is: to provide an erhu hexagonal qin tube slotter that is more convenient for the operator to slot the hexagonal qin tube, and can simultaneously slot the six sides of the hexagonal qin tube with high work efficiency

Embodiment 1

[0022] A slotter for an erhu hexagonal qin tube, such as Figure 1-3 As shown, it includes a base 1, a vertical plate 2, a support plate 3, a hexagonal hollow cylinder 4, a driving mechanism 5 and a slotting mechanism 6. The embedded one is equipped with a hexagonal hollow cylinder 4 that can place the hexagonal piano tube. The upper part of the front side of the support plate 3 is provided with a slotting mechanism 6. The front middle part of the top of the base 1 is fixed with a vertical plate 2. The upper part of the vertical plate 2 A driving mechanism 5 is provided between the left side of the bottom of the support plate 3 , and the driving mechanism 5 contacts and cooperates with the slotting mechanism 6 , and the driving mechanism 5 is also fixedly connected with the top of the base 1 .

[0023] The driving mechanism 5 includes a pedal 51, a ratchet bar 52, a ratchet wheel 53, a six-groove ring 54 and a first spring 55. The upper part of the rear side of the riser 2 is ...

Embodiment 2

[0029] On the basis of Example 1, such as figure 2 As shown, a fixing mechanism 7 is also included. The fixing mechanism 7 includes an L-shaped rod 71, a sleeve 72, a clamping rod 73 and a fourth spring 74. The rear side of the top of the pedal 51 is fixedly connected with an L-shaped rod 71. Two sleeves 72 are affixed to the right side of the inner top, and a sliding rod 73 is provided in the sleeve 72. A fourth spring 74 is connected between the top of the rod 73 and the inner top of the sleeve 72, and the bottom of the rod 73 It runs through the top of the hexagonal hollow cylinder 4 .

[0030] When the operator steps on the pedal 51 to move downward, the pedal 51 also drives the L-shaped rod 71 to move downward, and the downward movement of the L-shaped rod 71 drives the sleeve 72 to move downward, and the sleeve 72 moves downward through the fourth spring 74 Drive the clamping rod 73 to move downward, the clamping rod 73 moves downward to contact with the hexagonal pian...

Abstract

The invention relates to a slotting device, in particular to a slotting device for a six-sided tube of an erhu. The technical problem is how to design a slotting device for a six-sided tube of an erhu, which can provide conveniences for an operator to slot the six-sided tube, can realize simultaneous slotting of six surfaces of the six-sided tube and is high in work efficiency. The slotting devicefor the six-sided tube of the erhu comprises a base, and a vertical plate, wherein one side of the base is fixedly connected with a support plate; the middle of a part, far away from the base, of thesupport plate is fixedly connected with a six-sided hollow tube in a penetrating manner; and the vertical plate is fixedly connected to the side, close to the support plate, of the base. According tothe slotting device provided by the invention, the six-sided tube is placed inside the six-sided hollow tube, a pedal is treaded to move downwards, so that six saw-toothed plates move inwards to makecontact with the six-sided tube to slot the six-sided tube; in this way, the operation is more convenient; meanwhile the six surfaces of the six-sided tube can be simultaneously slotted; and the workefficiency is high.

Description

technical field [0001] The invention relates to a slotting device, in particular to a slotting device for an erhu hexagonal qin tube. Background technique [0002] Erhu began in the Tang Dynasty and is called "Xiqin". It has a history of more than one thousand years. It is a traditional Chinese stringed instrument. Erhu, that is, the Erxian Huqin, also known as "Nanhu" and "Omzi", is one of the main bowed stringed instruments in the family of Chinese musical instruments. In the process of making Erhu, the production of hexagonal qin tube is essential, but In order to make the hexagonal qin tube more beautiful, grooves will be made on the outside of the end of the hexagonal qin tube where the piano window is installed. [0003] At present, most of the grooves are made on the outside of the hexagonal qin tube by holding a tool by hand. First, one needs to press the hexagonal qin tube with one hand, and the other hand holds the grooving tool to open the hexagonal qin tube. G...
