Description

Technical Field

[0001] This utility model relates to the field of power tool holder processing technology, specifically a flexible flat coupling structure. Background Technology

[0002] Currently, the connection between tool holders and tool turrets on the market is a rigid connection. They are all connected by setting a square flat key on the connecting column to hold the flat coupling sleeve, and then connecting the tool holder through the flat connecting block on the flat coupling sleeve.

[0003] Currently, rigid connections have two main drawbacks: First, rigid connections place very high demands on the machining of parts (in many cases, the precision of the parts cannot meet the requirements); second, rigid connections experience significant vibration during operation, leading to a sharp increase in temperature and noise. As a result, tool holder products are very unstable in high-speed operation (above 12,000 rpm), which severely restricts the machining performance of tool holder products.

[0004] Therefore, a flexible flat coupling structure is needed to address this problem. Utility Model Content

[0005] The purpose of this invention is to provide a flexible flat coupling structure. This invention allows the flat coupling to be offset slightly in any direction to adapt to misalignment when connected to the tool turret, thereby eliminating vibration, noise, and temperature rise in high-speed operation (above 12,000 rpm), and greatly improving the machining performance of the tool holder product.

[0006] This utility model is implemented as follows:

[0007] A flexible flat coupling structure includes a turret body, a connection mechanism for connecting with a tool holder is provided on the turret body, the connection mechanism includes a flat coupling sleeve, and a flat connecting block is provided on the flat coupling sleeve.

[0008] A connecting post is provided on the flat coupling of the turret body to match the flat coupling sleeve. Multiple slots are evenly spaced on the outer wall of the connecting post, and the slots are "U" shaped slots.

[0009] Each of the six slots is fitted with a locking pin, which is evenly spaced on the outer wall of the connecting column. The locking pins are cylindrical.

[0010] Furthermore, the retaining pins are made of bearing steel cylindrical pins and polyurethane cylindrical pins, with three of each type, and the bearing steel and polyurethane cylindrical pins are spaced apart and engaged in the retaining grooves. Three cylindrical pins are replaced with polyurethane rods, allowing the flat coupling to make small offsets in any direction to accommodate misalignment when connected to the turret.

[0011] Furthermore, the inner wall of the flat coupling sleeve is provided with an embedded groove that matches the retaining groove for engaging the retaining pin. When the flat coupling sleeve is fitted onto the connecting post, the retaining pin on the connecting post engages in the embedded groove on the inner wall of the flat coupling sleeve. Thus, the flat connecting block on the flat coupling sleeve, driven by the tool holder, drives the flat coupling sleeve to rotate. The rotation of the flat coupling sleeve, through the retaining pin, drives the internal connecting post to rotate.

[0012] Furthermore, a resilient pin is provided through the flat coupling sleeve and the connecting column. The resilient pin can stably connect the flat coupling sleeve and the connecting column in the horizontal direction, preventing the flat coupling sleeve from shifting horizontally from the connecting column.

[0013] Furthermore, the working principle of this utility model is as follows: Unlike the traditional structure that uses two flat keys to transmit torque, this utility model adopts a six-cylinder pin structure. The cylindrical pins of this utility model are evenly distributed on the circumference of the connecting column. This structure transmits greater torque and provides smoother transmission. Three of the cylindrical pins are replaced with polyurethane rods, allowing the flat coupling to make slight offsets in any direction to adapt to misalignment when connected to the tool turret. This eliminates vibration, noise, and temperature rise in high-speed operation (above 12,000 rpm), greatly improving the machining performance of the tool holder product.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The flat coupling allows for slight offset in any direction to accommodate misalignment when connected to the tool turret, thereby eliminating vibration, noise, and temperature rise in high-speed operation (above 12,000 rpm), and greatly improving the machining performance of the tool holder.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1-2 A flexible flat coupling structure includes a turret body 1, a connection mechanism for connecting with a tool holder is provided on the turret body 1, the connection mechanism includes a flat coupling sleeve 2, and a flat connecting block 21 is provided on the flat coupling sleeve 2.

[0022] A connecting post is provided on the flat coupling 3 of the turret body 1 to match the flat coupling sleeve 2. Multiple slots are evenly spaced on the outer wall of the connecting post, and the slots are U-shaped slots.

[0023] Each of the six slots is fitted with a locking pin, which is evenly spaced on the outer wall of the connecting column. The locking pins are cylindrical.

[0024] In this embodiment of the invention, the locking pins are bearing steel cylindrical pins and polyurethane cylindrical pins, with three of each type: a first polyurethane cylindrical pin 41, a second polyurethane cylindrical pin 42, and a third polyurethane cylindrical pin 43; a first bearing steel cylindrical pin 51, a second bearing steel cylindrical pin 52, and a third bearing steel cylindrical pin 53. These bearing steel and polyurethane cylindrical pins are spaced apart and locked within the locking grooves. The three cylindrical pins are replaced with polyurethane rods, allowing the flat coupling to make small offsets in any direction to accommodate misalignment when connected to the turret.

[0025] In this embodiment of the present invention, an embedded groove matching the retaining groove is provided on the inner wall of the flat coupling sleeve for engaging the retaining pin. When the flat coupling sleeve is fitted onto the connecting column, the retaining pin on the connecting column engages in the embedded groove on the inner wall of the flat coupling sleeve. Thus, the flat connecting block on the flat coupling sleeve, driven by the tool holder, drives the flat coupling sleeve to rotate. The rotation of the flat coupling sleeve, through the retaining pin, drives the internal connecting column to rotate. A resilient pin 6 penetrates the flat coupling sleeve 2 and the connecting column. The resilient pin stably connects the flat coupling sleeve and the connecting column in the horizontal direction, preventing the flat coupling sleeve from shifting horizontally from the connecting column.
