Description

Technical Field

[0001] This utility model relates to the field of imperial cutting tools, and in particular to a novel imperial-to-metric spring cutter sleeve structure. Background Technology

[0002] Currently, the tool holders and sheaths used in production are divided into two types: imperial and metric. Imperial tool holders and sheaths are used to hold imperial tools, while metric tool holders and sheaths are used to hold metric tools.

[0003] However, in the actual production process of products in the factory, both imperial tools are used to process imperial dimensions, and metric tools are used to process metric dimensions. Therefore, machine tool accessories need to be equipped with both imperial tool holders and tool sleeves and metric tool holders and tool sleeves.

[0004] During the machining process, incidents of incorrectly installing metric tool holders and sleeves on imperial tools or vice versa occur frequently, causing safety and quality hazards. Furthermore, the need for a complete range of metric and imperial tool holder and sleeve specifications increases production costs. Therefore, developing a novel imperial-to-metric spring-loaded tool sleeve structure has become an urgent problem for those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide a novel imperial-to-metric spring tool holder structure to solve the problem that during the machining process, imperial tools are often mistakenly installed with metric tool holders or tool holders, or metric tools are mistakenly installed with imperial tool holders or tool holders, causing potential safety and quality hazards.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model discloses a novel imperial-to-metric spring-loaded knife sheath structure, comprising a knife sheath body, an imperial inner circle, a lower-opening spring groove, a metric outer circle, and an upper-opening spring groove. The knife sheath body is cylindrical, with an imperial inner circle that mates with an imperial cutting tool. The outer circle of the knife sheath body is metric, mates with a metric tool shank and a metric knife sheath. The knife sheath body is provided with an upper-opening spring groove facing upwards and a lower-opening spring groove facing downwards.

[0007] Furthermore, the upper opening elastic groove and the lower opening elastic groove are alternately arranged.

[0008] Furthermore, the specific number of the upper-opening elastic grooves is three.

[0009] Furthermore, the three upper-opening elastic grooves are evenly arranged on the main body of the blade sheath.

[0010] Furthermore, the specific number of the lower opening elastic grooves is three.

[0011] Furthermore, the three lower opening elastic grooves are evenly arranged on the main body of the blade sleeve.

[0012] Furthermore, both the lower and upper opening elastic grooves include a circular through hole and a through vertical slit.

[0013] Furthermore, the lower opening elastic groove and the upper opening elastic groove are symmetrically arranged along the center line of the blade sleeve body.

[0014] Furthermore, the main body of the blade sheath is made of alloy spring steel.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows: This utility model relates to a novel imperial-to-metric spring-loaded tool holder structure, comprising a tool holder body made of alloy spring steel and hardened to provide excellent elastic strength and durability. The tool holder body has a metric outer circle and an imperial inner circle. The metric outer circle mates with metric tool holders and metric tool holders, while the imperial inner circle can hold imperial tools. This allows existing metric tool holders and metric tool holders to hold both metric and imperial tools, effectively saving production costs, improving production efficiency, and reducing safety and quality risks. In summary, this novel imperial-to-metric spring-loaded tool holder structure is ingeniously designed, functionally practical, and structurally simple. It effectively solves the problem of incorrectly installing imperial tools with metric tool holders or metric tools with imperial tool holders or tool holders during processing, causing safety and quality hazards. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings: Figure 1 This is a front view of the novel imperial-to-metric spring cutter sleeve structure of this utility model; Figure 2 This is an isometric drawing of the novel imperial-to-metric spring cutter sleeve structure of this utility model.

[0017] Explanation of reference numerals in the attached diagram: 1. Main body of the blade sheath; 2. Imperial inner circle; 3. Lower opening spring groove; 4. Metric outer circle; 5. Upper opening spring groove. Detailed Implementation

[0018] like Figure 1 and Figure 2 As shown, a novel imperial-to-metric spring cutter sleeve structure includes a sleeve body 1, an imperial inner circle 2, a lower-opening spring groove 3, a metric outer circle 4, and an upper-opening spring groove 5.

[0019] The main body 1 of the tool sheath is cylindrical. The interior of the main body 1 is an imperial inner circle 2, which mates with imperial cutting tools. The exterior of the main body 1 is a metric outer circle 4, which mates with metric tool holders and metric tool sheaths. The main body 1 is made of alloy spring steel and is hardened, giving it good elastic strength and durability.

[0020] The blade sheath body 1 is provided with an upper open elastic groove 5 with an upward opening and a lower open elastic groove 3 with a downward opening. Both the lower open elastic groove 3 and the upper open elastic groove 5 include a circular through hole and a through vertical slit.

[0021] Specifically, the upper open elastic groove 5 and the lower open elastic groove 3 are alternately arranged. There are three upper open elastic grooves 5, which are evenly distributed on the blade sheath body 1. Similarly, there are three lower open elastic grooves 3, which are also evenly distributed on the blade sheath body 1.

[0022] The lower opening elastic groove 3 and the corresponding upper opening elastic groove 5 are symmetrically arranged along the center line of the tool holder body 1. This ensures that all three pairs of upper opening elastic grooves 5 and lower opening elastic grooves 3 are symmetrically arranged. The upper opening elastic grooves 5 and lower opening elastic grooves 3 are arranged circumferentially and positioned opposite each other, enabling the tool holder body 1 to clamp the tool.

[0023] This utility model relates to a novel imperial-to-metric spring-loaded tool holder structure. The tool holder body 1 has a metric outer circle 4 and an imperial inner circle 2. The metric outer circle 4 mates with metric tool holders and metric tool holders, while the imperial inner circle 2 can clamp imperial tools. This allows existing metric tool holders and metric tool holders used in production to clamp both metric and imperial tools, solving the problem of tool holder / tool ​​incompatibility caused by the mixed use of imperial and metric tool holders / holders. It also avoids the problem of insecure clamping caused by mistakenly installing imperial tools with metric tool holders / holders. This novel imperial-to-metric spring-loaded tool holder structure uses only one set of metric collets to clamp both metric and imperial tools, effectively saving production costs.

[0024] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
