Description

Technical Field

[0001] The utility model relates to the technical field of blade processing fixtures, in particular to a blade fixture. Background Art

[0002] In the field of blade machining fixture technology, traditional blade fixtures typically use pins for positioning. However, this positioning method presents several challenges. First, the inner wall of the positioning pin hole may contain small amounts of impurities, such as metal debris and dust. These impurities can cause the pin to become stuck during installation, affecting positioning accuracy and stability.

[0003] Secondly, due to the tight fit, air inside the dowel pin hole cannot be exhausted, creating air blockage during pin installation, making installation difficult and potentially damaging the pin or dowel pin hole. Furthermore, existing blade fixtures also have deficiencies in exhaust, often lacking dedicated exhaust structures or having poorly designed exhaust structures, resulting in poor exhaust performance.

[0008] Furthermore, the positioning pin hole is provided with a tightening screw hole, and the exhaust hole and the tightening screw hole are communicated with the outside through the clamping mechanism; and an elastic component is provided at the bottom of the positioning pin hole.

[0009] Furthermore, when the positioning pin holes are arranged in a row on the same plane, the multiple positioning pin holes in the same row are connected through an exhaust hole.

[0010] Furthermore, when the positioning pin holes are arranged in multiple rows on the same plane, the multiple rows of positioning pin holes are connected to one exhaust hole through the oblique exhaust holes.

[0011] Furthermore, the horizontal position of the exhaust hole connected to the positioning pin hole is higher than that of the discharge hole.

[0012] Furthermore, the inner diameter of the exhaust hole connected to the positioning pin hole is larger than the inner diameter of the discharge hole.

[0013] Furthermore, the inner diameter of the exhaust hole changes gradually.

[0029] Specific examples

[0030] The present invention will be described in detail below with reference to the accompanying drawings.

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] In this embodiment, if Figure 1 、 2 As shown, a blade clamp comprises: a clamping mechanism 1, a positioning pin hole 2 and a positioning pin shaft 3, wherein the positioning pin hole 2 is provided in the clamping mechanism 1, and the positioning pin hole 2 is provided with a pin shaft 3;

[0033] The positioning pin hole 2 is provided with an exhaust hole 4 .

[0034] In this embodiment, the exhaust hole 4 is arranged perpendicularly to the positioning pin hole 2, and both ends of the exhaust hole 4 pass through the fixture to form a T-shaped airway with the positioning pin hole 2;

[0035] This design effectively solves the aforementioned problems. First, the vent holes 4 allow air to escape from the locating pin holes 2, thereby preventing unstable installation caused by air not being able to escape. Second, the vent holes 4 also allow impurities such as metal debris to escape from the locating pin holes 2, thereby preventing the blade from becoming stuck. Furthermore, the blade clamp of this utility model offers the advantage of low cost.

[0036] Furthermore, the positioning pin hole 2 is provided with a tightening screw hole 7, and the exhaust hole 4 and the tightening screw hole 7 are connected to the outside through the clamping mechanism 1; an elastic component 6 is provided at the bottom of the positioning pin hole 2

[0037] Such a design makes the exhaust smoother and further improves the use effect of the blade clamp. At the same time, a tightening screw hole 7 is added, and a bolt is set in the tightening screw hole 7 to tighten the pin shaft 3, which can effectively prevent the pin shaft 3 from falling out during operation.

[0038] An elastic component 6 is provided at the bottom of the positioning pin hole 2. After the bolt in the tightening screw hole 7 is withdrawn, the pin shaft 3 pops out of the pin hole, simplifying the operation procedure.

[0039] Furthermore, when the positioning pin holes 2 are arranged in a row on the same plane, the multiple positioning pin holes 2 in the same row are connected through an exhaust hole 4.

[0040] Specifically, when the positioning pin holes 2 are arranged in a row, such as three positioning pin holes 2 in a row, an exhaust hole 4 is set at the bottom of the three positioning pin holes 2 to connect the three positioning pin holes 2 in series. Both ends of the exhaust hole 4 pass through the fixture and exhaust is discharged at both ends.

[0041] Such a design allows a plurality of positioning pin holes 2 to share one exhaust hole 4, thereby simplifying the structure and reducing the manufacturing cost.

[0042] Furthermore, when the positioning pin holes 2 are arranged in multiple rows on the same plane, the multiple rows of positioning pin holes 2 are connected to one exhaust hole 4 through the oblique exhaust holes 4 .

[0043] Specifically, when multiple rows of positioning pin holes 2 are provided, such as two rows of three positioning pin holes 2, exhaust holes 4 are provided in parallel with the two rows of positioning pin holes 2 at the middle position of the bottom of the two rows of positioning pin holes 2. Extended oblique holes are used at the bottom of the two rows of positioning pin holes 2 to lead to the exhaust holes 4, and multiple positioning pin holes 2 are connected in series. Both ends of this exhaust hole 4 pass through the fixture, and exhaust is discharged at both ends.

[0044] Such a design allows multiple rows of positioning pin holes 2 to share one exhaust hole 4, further simplifying the structure and reducing manufacturing costs.

[0045] Furthermore, the horizontal position of the exhaust hole 4 connected to the positioning pin hole 2 is higher than that of the discharge hole.

[0046] The exhaust hole 4 is in an inverted V-shaped structure to facilitate the discharge of impurities;

[0047] The horizontal position of the exhaust hole 4 where it connects to the positioning pin hole 2 is higher than the exhaust hole. This design allows the air flow to flow more smoothly from the positioning pin hole 2 to the exhaust hole 4, thereby improving the exhaust effect.

[0048] Furthermore, the inner diameter of the exhaust hole 4 where it connects to the positioning pin hole 2 is larger than the inner diameter of the discharge hole.

[0049] This design allows the airflow to flow more smoothly from the positioning pin hole 2 to the exhaust hole 4, thereby improving the exhaust effect.

[0050] Furthermore, the inner diameter of the exhaust hole 4 changes gradually.

[0051] This design ensures that the airflow will not be obstructed when flowing in the exhaust hole 4, further improving the exhaust effect.

[0052] Furthermore, the air vent 4 is chamfered at the connection with the positioning pin hole 2 .

[0053] This design allows the airflow to flow more smoothly from the positioning pin hole 2 to the exhaust hole 4, thereby improving the exhaust effect.

[0054] Furthermore, a splash-proof filter 5 is provided at the outlet end of the exhaust hole 4 .

[0055] The air outlet of the exhaust hole 4 is provided with a splash-proof filter 5. Such a design can prevent impurities from splashing out and protect the safety of the operator.

[0056] Furthermore, a smooth coating layer is provided in the exhaust hole 4 .

[0057] This design can reduce frictional resistance and improve the flow performance of airflow.

[0058] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
