Description

Technical Field

[0001] This utility model belongs to the field of wood chisel technology, specifically relating to a wood chisel sharpening tool. Background Technology

[0002] The last step in wood chisel processing is sharpening the cutting edge. During the width sharpening process, due to wear of the grinding wheel and issues with the flatness of the worktable, the dimensions of the front and back three positions of the wood chisel width cannot be guaranteed to be absolutely consistent after sharpening. A large-area contact cannot guarantee a certain clamping force, so a two-point clamping method is needed to solve the problem. Utility Model Content

[0003] Purpose of the utility model: To solve the clamping problem caused by inconsistent front and rear dimensions of the width of a wooden chisel, this utility model proposes a wooden chisel grinding edge clamp.

[0004] Technical solution: A wood chisel sharpening fixture, comprising: fixture body, slider drive, slider, clamping block, movable block, guide rod, wood chisel, support block and guide wheel;

[0005] The wooden chisel is mounted at one end of the clamp body via a support block;

[0006] The slider drive is connected to the slider and is used to drive the slider to move back and forth on the clamp body. Both are set at the other end of the clamp body. The slider is provided with an irregular groove, the front end of which is away from the wood chisel and the rear end of which is close to the wood chisel.

[0007] The clamping block is movably disposed on the upper surface of the movable block and is used to contact the wooden chisel to clamp the wooden chisel.

[0008] The movable block is movably connected to the fixture body via a guide rod. A fixed plate is provided at the lower end of the movable block on the side away from the wood chisel. The guide wheel is fixedly mounted on the fixed plate and is located in the irregular groove on the slider. The guide wheel drives the movable block to move along the guide rod on the fixture body to move closer to / away from the wood chisel along the irregular groove.

[0009] Furthermore, a pair of protrusions are provided on the side of the clamping block near the wooden chisel, the protrusions being used to contact the wooden chisel and clamp it.

[0010] Furthermore, the clamping block is provided with a first through hole and a second through hole. The clamping block is movably disposed on the upper surface of the movable block through the two through holes and the shaft ring, and the second through hole is an elliptical through hole.

[0011] Furthermore, the slider drive component is a cylinder.

[0012] Beneficial effects: Compared with the prior art, the clamp proposed in this utility model can achieve the effect of simultaneously clamping the wood chisel when either the upper or lower position of the clamping block contacts the wood chisel, and the other position will rotate to contact the wood chisel.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model.

[0020] In the description of this utility model, it should be understood that the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0021] Furthermore, in this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] In this utility model, "up," "down," "left," and "right" are descriptions of specific orientations in actual use based on the accompanying drawings.

[0023] like Figures 1 to 6 As shown, this embodiment proposes a wood chisel sharpening fixture, which mainly includes: a baffle 1, a cylinder 2, a slider 3, a shaft ring 4, a clamping block 5, a movable block 6, a guide sleeve 7, a guide post 8, a wood chisel 9, a support block 10, a fixture body 11, and a guide wheel 12. The support plate 10 is disposed on one side of the fixture body 11, the wood chisel 9 is placed on the support plate 10, the cylinder 2 is disposed on the other side of the fixture body 11, and the working end of the cylinder 2 is connected to the slider 3. A space is provided on the other side of the fixture body 11 for the slider 3 to slide back and forth. An irregularly shaped groove is provided on the slider 3, and the guide wheel 12 is placed in the irregularly shaped groove.

[0024] like Figure 4 As shown, the clamping block 5 is mounted on the upper surface of the movable block 6 via a pair of shaft rings 4. A fixed plate extends from one side of the bottom of the movable block 6 towards the other side of the clamp body 11, and the guide wheel 12 is fixed to the fixed plate. The guide post 8 is fixed inside the movable block 6 via a guide sleeve 7, and extends towards one side of the clamp body 11. The movable block 6 is located in the middle section of the clamp body 11, between the support block 10 and the cylinder 2. The guide post 8 extending towards one side of the clamp body 11 and the guide wheel 12 placed in the irregularly shaped groove allow the movable block 6 to move left and right in the middle section of the clamp body 11. The baffle 1 is used to cover the slider 3 and the movable block 6.

[0025] To enable the movable block 6 to move left and right at the middle section of the fixture body 11, such as Figure 2 As shown, in this embodiment, the front end of the irregularly shaped slide is close to the other side of the clamp body 11, and the rear end is close to the other side of the clamp body 11. When the cylinder pulls the slider 3 to move backward, the guide wheel 12 moves from the rear end of the irregularly shaped slide to the front end, forcing the movable block 6 to move to the other side of the clamp body 11, that is, to the right. When the cylinder pushes the slider 3 to move forward, the guide wheel 12 moves from the front end of the irregularly shaped slide to the rear end, forcing the movable block 6 to move to the left. When the movable block 6 moves to the left, the clamping block 5 on the upper surface of the movable block 6 contacts the wood chisel 9 and cooperates with the support block 10 to clamp the wood chisel 9.

[0026] To address the issue of inconsistent width between the front and rear of the wooden chisel, the clamping block 5 in this embodiment has a protrusion at each end on the side closest to the wooden chisel 9 for contacting the chisel 9. This clamping block 5 is floatingly mounted on the movable block 6. Specifically, as shown... Figure 2As shown, the clamping block 5 is provided with a first through hole and a second through hole. The first through hole is located in front of the second through hole. Each through hole is provided with a shaft ring 4. Through the shaft ring 4, the clamping block is floatingly set on the upper surface of the movable block 6. The second through hole is an elliptical through hole. Through the elliptical through hole, the clamping block 5 can be closer to the wood chisel 9 or further away from the wood chisel 9, so as to clamp the wood chisel with inconsistent front and rear dimensions.

[0027] The working process of the clamp in this embodiment is as follows: the cylinder 2 pushes the slider 3 forward, the irregular groove in the slider 3 drives the guide wheel 12, and then causes the movable block 6 to move to the left. The clamping block 5 floats on the movable block 6. When the clamping block 5 contacts the wood chisel 9 at any position above or below, it will rotate to adjust the other position to contact the wood chisel 9, so as to achieve the effect of clamping the wood chisel at both positions above and below.
