Description

Technical Field

[0001] This utility model relates to the field of milling cutters, and in particular to a milling cutter structure with positioning function. Background Technology

[0002] In modern machining, milling, as an important metal cutting method, is widely used in the manufacturing and processing of various parts. In traditional milling, whenever the milling cutter needs to be changed, the operator must perform a tool setting operation again to ensure the accurate position of the cutter and machining precision. This process is not only time-consuming but also requires a certain level of skill from the operator, increasing the uncertainty and risk of human error in the machining process. In machining tasks that require frequent tool changes, tool setting time accounts for a significant portion of the total machining time, hindering the improvement of machining efficiency.

[0003] Since tool setting needs to be repeated after each tool change, factors such as differences in tool setting between different operators, the precision limitations of tool setting equipment, and changes in environmental factors can all lead to slight deviations in the position of the milling cutter after each tool setting. These deviations accumulate and are amplified when machining multiple workpieces consecutively, ultimately affecting the consistency of machining accuracy and reducing product quality stability. Utility Model Content

[0004] The purpose of this invention is to provide a milling cutter structure with positioning function, which solves the problem of traditional milling cutters requiring tool resetting and being cumbersome and time-consuming when changing tools.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a milling cutter structure with positioning function, including a cutter holder, a cutter head provided at one end of the cutter holder, a positioning sleeve slidably connected to the outside of the cutter holder, and an adjustment structure provided on the positioning sleeve, the adjustment structure being used to adjust the tightness between the positioning sleeve and the cutter holder.

[0006] Preferably, the adjustment structure includes a threaded rod, and the positioning sleeve is internally threaded with the threaded rod, and the threaded rod is perpendicular to the tool holder.

[0007] Preferably, the end of the threaded rod away from the tool holder is provided with a hexagonal groove, which facilitates the rotation of the threaded rod using tools such as a hexagonal wrench.

[0008] Preferably, the two ends of the positioning sleeve extend outward in a ring shape to form baffles. The adjustment structure includes a sleeve, a spring, and ball bearings. The sleeve is slidably connected to the outside of the positioning sleeve. The inner diameter of the upper part of the sleeve is the same as the outer diameter of the positioning sleeve. The middle part of the sleeve is trumpet-shaped. The inner diameter of the lower part of the sleeve is larger than the outer diameter of the positioning sleeve. A spring is sleeved on the outside of the positioning sleeve. The sleeve is elastically connected to the corresponding baffle through the spring. Ball bearings are equidistantly connected to the inside of the positioning sleeve. Grooves arranged in a ring array are equidistantly opened on the outside of the tool handle. The ball bearings are respectively stuck in the grooves at corresponding positions on the tool handle.

[0009] Preferably, the lower part of the sleeve has anti-slip texture on the outer side to increase the friction when the sleeve is manually dragged to slide.

[0010] Preferably, the positioning sleeve is U-shaped, and the adjustment structure includes an adjustment rod and a compression cap. The adjustment rod passes through the two ends of the positioning sleeve in sequence, and the compression cap is threaded to the outer side of one end of the adjustment rod.

[0011] Preferably, the extrusion cap is provided with symmetrical ears on the outer side, which makes it convenient for the operator to manually twist the extrusion cap.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. This utility model, through the cooperation of the positioning sleeve and the tool holder, eliminates the need for re-setting the tool after the initial tool setting. The milling cutter can easily reach the predetermined machining position, saving tool changing and tool setting time and significantly improving machining efficiency. The precise positioning function of the positioning sleeve ensures that the same machining position is reached every time the milling cutter is assembled, avoiding the decrease in machining accuracy caused by tool setting errors, thereby improving the overall machining quality.

[0014] 2. This utility model makes adjusting the tightness of the positioning sleeve simple and quick through the adjustment structure. Whether it is through the cooperation of the threaded rod, sleeve and ball, or through the combination of the adjusting rod and the compression cap, easy and quick positioning adjustment can be achieved, reducing the difficulty of operation and improving the convenience of work.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 A milling cutter structure with positioning function includes a cutter holder 1, a cutter head 2 is provided at one end of the cutter holder 1, a positioning sleeve 3 is slidably connected to the outside of the cutter holder 1, and an adjustment structure 4 is provided on the positioning sleeve 3. The adjustment structure 4 is used to adjust the tightness between the positioning sleeve 3 and the cutter holder 1.

[0022] After the initial tool setting is completed, slide the positioning sleeve 3 along the tool holder 1 until it abuts against the assembled tool holder. Then, fix the positioning sleeve 3 on the tool holder 1 by adjusting the structure 4. When the milling cutter is assembled again, the positioning sleeve 3 abuts against the tool holder so that the milling cutter can automatically reach the predetermined machining position without needing to set the tool again.

[0023] Example 1

[0024] This embodiment uses the first type of positioning sleeve 3 and adjustment mechanism. Please refer to [link / reference]. Figure 1 The adjusting structure 4 includes a threaded rod 41. The positioning sleeve 3 is internally threaded with the threaded rod 41, and the threaded rod 41 is perpendicular to the tool holder 1.

[0025] By rotating the threaded rod 41, the tightness between the end of the threaded rod 41 and the tool holder 1 is controlled, so as to achieve the positioning of the tool holder 1. This positioning method has a simple structure, is easy to adjust, and the positioning sleeve 3 can be positioned at any position on the tool holder 1.

[0026] The threaded rod 41 has a hexagonal groove 411 at the end away from the tool holder 1, so that the threaded rod 41 can be rotated by tools such as a hexagonal wrench, thereby making it easier to adjust the tightness between the end of the threaded rod 41 and the tool holder 1.

[0027] Example 2

[0028] This embodiment uses the second type of positioning sleeve 3 and adjustment mechanism. Please refer to [link / reference]. Figure 2 and Figure 3 The two ends of the positioning sleeve 3 extend outward in a ring shape to form baffles 31. The adjustment structure 4 includes a sleeve 42, a spring 43 and ball bearings 44. The sleeve 42 is slidably connected to the outside of the positioning sleeve 3. The inner diameter of the upper part of the sleeve 42 is the same as the outer diameter of the positioning sleeve 3. The middle part of the sleeve 42 is trumpet-shaped. The inner diameter of the lower part of the sleeve 42 is larger than the outer diameter of the positioning sleeve 3. The spring 43 is sleeved on the outside of the positioning sleeve 3. The sleeve 42 is elastically connected to the corresponding baffle 31 through the spring 43. Ball bearings 44 are equidistantly slidably connected inside the positioning sleeve 3. The outer side of the knife handle 1 is provided with grooves 11 arranged in a ring array at equal intervals. The ball bearings 44 are respectively stuck in the grooves 11 at the corresponding positions on the knife handle 1.

[0029] Under normal conditions, the sleeve 42 is held in the corresponding position and cannot slide due to the restriction of the spring 43. Part of the ball 44 is inside the positioning sleeve 3 and its edge abuts against the upper part of the sleeve 42 and is restricted by the sleeve 42 and cannot move. The other part of the ball 44 is stuck in the groove 11 at the corresponding position on the handle 1, thereby realizing the positioning of the positioning sleeve 3.

[0030] When it is necessary to adjust the positioning sleeve 3, manually drag the sleeve 42 to slide it so that the ball 44 is flush with the lower part of the sleeve 42, so that the ball 44 has a certain amount of room to move, so that part of the ball 44 slides into the gap between the lower part of the sleeve 42 and the positioning sleeve 3, and separates from the groove 11. Then the positioning sleeve 3 can be slid to adjust the position.

[0031] Compared to Embodiment 1, this adjustment method does not require additional tools, making it more convenient and easier to adjust. Moreover, the positioning sleeve 3 is more secure and stable during positioning in this method. However, it requires setting a groove 11 on the handle 1, making the structure more complex than the embodiment in claim 1.

[0032] The lower outer side of the sleeve 42 is provided with anti-slip texture to increase the friction when the sleeve 42 is manually dragged, making it easier for the operator to adjust the position of the sleeve 42 more stably and effortlessly.

[0033] Example 3

[0034] This embodiment uses the third type of positioning sleeve 3 and adjustment mechanism. Please refer to [link / reference]. Figure 4 The positioning sleeve 3 is U-shaped. The adjustment structure 4 includes an adjustment rod 45 and a compression cap 46. The adjustment rod 45 passes through the two ends of the positioning sleeve 3 in sequence. The compression cap 46 is threaded to the outer side of one end of the adjustment rod 45.

[0035] By twisting the compression cap 46, the positioning sleeve 3 is deformed under the action of the adjusting rod 45, thereby adjusting the tightness between the positioning sleeve 3 and the tool holder 1. The positioning sleeve 3 is made of plastic material and has a certain deformation capacity. Compared with Embodiment 1 and Embodiment 2, this positioning sleeve 3 can adapt to tool holders 1 within a certain range of thickness and is more convenient to adjust. However, it is not as good as Embodiment 1 and Embodiment 2 in terms of quality and service life.

[0036] The extrusion cap 46 is symmetrically provided with lugs 461 on the outside. The lugs 461 make it easier for the operator to manually turn the extrusion cap 46, thereby making it easier to adjust the tightness between the positioning sleeve 3 and the tool holder 1.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
