Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder manufacturing technology, and more specifically, to a circular non-standard tool holder. Background Technology

[0002] The tool holder used for scraping and burnishing tools is a specially designed fixture used to fix and support the scraping and burnishing tools to ensure that the tools can work stably and accurately during the machining process.

[0003] Currently, the tool holders used for traditional scraping and burnishing tools are expensive, the machined surfaces are relatively rough, and the stability is poor. They often use square blades, which are prone to wear. At the same time, traditional tool holders are prone to chip accumulation, which affects processing efficiency and surface quality.

[0004] Therefore, in view of this, we have studied and improved the existing structure to provide a circular non-standard tool holder, in order to achieve a more practical purpose. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a circular non-standard tool holder, which can improve the cutting position of the blade, enhance the utilization rate of the cutting edge, reduce the use cost of scraping and burnishing tools, improve machining accuracy and stability, improve the surface finish of the machined workpiece, reduce wear and tear, and at the same time avoid chip accumulation, ensuring machining efficiency and surface quality of the machined products.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A circular non-standard knife clip includes a knife clip box body, wherein the knife clip box body has a stepped structure, consisting of a continuously arranged upper stepped layer, a side cut surface and a middle stepped layer, with the middle stepped layer located between the upper stepped layer and the bottom end face of the knife clip box body.

[0010] A vertical mounting circular hole groove structure is provided between the top of the upper ladder layer and the bottom surface of the tool holder box. A circular through hole groove and a strip through hole are provided between the middle ladder layer and the bottom surface of the tool holder box. A horizontal mounting circular hole groove structure is provided on the lateral side of the tool holder box. A circular tool mounting groove is provided on the side cut surface, and the circular tool mounting groove is located between the upper ladder layer and the middle ladder layer.

[0011] Furthermore, the surface of the upper ladder layer is a sloping structure, and the upper port of the vertically installed circular hole groove structure is located at the center of the upper ladder layer.

[0012] Furthermore, the lateral mounting circular hole groove structure extends from one lateral side of the tool holder box to the other lateral side.

[0013] Furthermore, the strip-shaped through-hole has an edge line on one side that is in the same plane as the side cut surface.

[0014] Furthermore, the circular through-hole groove is located at the edge of the middle ladder layer near the included angle.

[0015] Furthermore, the circular tool mounting groove includes a circular tool slot and a tool holder locking slot, which are integrally connected.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] In this solution, a circular insert can be installed on the tool holder, which increases the cutting position of the insert and thus enhances the utilization rate of the cutting edge. This effectively reduces the cost of using scraping and burnishing tools. Secondly, the circular insert can make the cutting force more uniform, reduce vibration, improve machining accuracy, and provide better stability in deep hole machining. There is no risk of vibration marks, and the stability is high. Because the surface of the circular insert is smooth, it improves the surface finish of the machined workpiece and reduces wear.

[0019] Then, a path is formed on the tool holder to guide the chip removal, which can avoid chip accumulation and ensure processing efficiency and surface quality of processed products. Attached Figure Description
