Description

Technical Field

[0001] This utility model specifically relates to a tool structure with a diamond-shaped pattern rolled on the end face of a product. Background Technology

[0002] Currently, knurling on the outer end face of aluminum bushings in automotive parts is generally done using single-blade diamond teeth and double-blade helical teeth structures. Because the aluminum bushing is annular with a difference in inner and outer diameter, the single-blade diamond teeth and double-blade helical teeth knurling methods result in inconsistent pattern depth, easily causing tooth irregularities during secondary processing and affecting pattern strength. Furthermore, when mounted on a machine tool, a fixed, flexible tool holder is required, limiting the height of the knurling tool center relative to the maximum product dimension, resulting in poor adjustability. This also leads to poor chip removal and irregular patterns during processing. Therefore, we propose a tool structure for knurling diamond patterns on the product end face. Utility Model Content

[0003] The purpose of this utility model is to provide a tool structure for knurling diamond patterns on the end face of a product, in order to solve the problems mentioned in the background art, such as inconsistent pattern depth of existing tools during knurling of aluminum bushing end faces, resulting in tooth misalignment during subsequent processing, poor adjustment during installation, and poor chip removal during processing.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tool structure with a diamond-shaped pattern rolled on the end face of a product, comprising:

[0005] A blade bar, wherein mounting holes are provided on the inner side of the blade bar, and the two ends of the mounting holes penetrate through the adjacent two side walls of the blade bar;

[0006] The first mandrel is disposed inside the mounting hole;

[0007] The second mandrel is arranged side by side with the first mandrel, and both the second mandrel and the first mandrel have knurling cutters on their outer surfaces.

[0008] Preferably, the inner diameter of the mounting hole is the same as the outer diameter of the first mandrel, and the mounting hole is inclined.

[0009] Preferably, the angle between the first mandrel and the second mandrel along the axial direction is 90° < α < 180°.

[0010] Preferably, the front surface of the blade rack is provided with an adjustment hole, and the inner side of the adjustment hole has a limiting bolt for clamping the first mandrel.

[0011] Preferably, the knurling cutter has a frustum-shaped cross-section.

[0012] Preferably, the lower surface of the blade bar has a chip discharge port corresponding to the knurling blade, and the chip discharge port is offset from one end of the mounting hole.

[0013] Preferably, the blade array is rectangular.

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

[0015] This utility model features a rigid tool connection, making it convenient, stable, and reliable to use. The knurling on the end face of the part bushing can be processed synchronously from front to back using two knurling cutters, ensuring consistent pattern depth and high efficiency. When changing to different products, the tool set is easy to install, disassemble, and adjust. The height of the knurling cutters is also easy to adjust, with good adjustment effect. Chip removal is smooth during processing, and it is easy to use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a tool structure with a diamond-shaped pattern rolled on the end face of a product, comprising:

[0023] The cutter bar 1 has mounting holes 4 on its inner side, and the two ends of the mounting holes 4 penetrate the adjacent side walls of the cutter bar 1, so as to facilitate the side-by-side installation of the first spindle 5 and the second spindle 6.

[0024] The first spindle 5 is located inside the mounting hole 4;

[0025] The second mandrel 6 is arranged side by side with the first mandrel 5, and both the second mandrel 6 and the first mandrel 5 are provided with knurling cutters 2 on their outer surfaces. This allows for simultaneous front and rear processing by the two knurling cutters 2 during knurling, ensuring consistent pattern depth.

[0026] In this embodiment, preferably, the inner diameter of the mounting hole 4 is the same as the outer diameter of the first mandrel 5, and the mounting hole 4 is inclined to facilitate the installation and the formation of an included angle, so that the end face of the bushing product 8 can be knurled simultaneously by two knurling cutters 2.

[0027] In this embodiment, preferably, the angle between the first mandrel 5 and the second mandrel 6 along the axial direction is 90° < α < 180°, which facilitates a better knurling effect.

[0028] In this embodiment, preferably, the front surface of the cutter bar 1 is provided with an adjustment hole 3, and the inner side of the adjustment hole 3 is provided with a limiting bolt for clamping the first mandrel 5, so as to facilitate the adjustment of the position of the knurling cutter 2 to adapt to the processing requirements of different products.

[0029] In this embodiment, preferably, the knurling cutter 2 has a frustum-shaped cross-section to facilitate a better knurling area.

[0030] In this embodiment, preferably, the lower surface of the blade rack 1 is provided with a chip discharge port 7 corresponding to the knurling blade 2, and the chip discharge port 7 is offset from one end of the mounting hole 4 to facilitate chip discharge.

[0031] In this embodiment, preferably, the blade row 1 is rectangular.

[0032] The working principle and usage process of this utility model are as follows: In use, the tool rack 1 is connected and fixed to the machine tool tool post and the middle support plate. When the machine tool spindle bushing product 8 and the machine tool lead screw rotate simultaneously, the rotation of the lead screw drives the middle support plate and the tool rack 1 to feed forward, backward, left and right. The product 8 can complete the knurling process by contacting the knurling cutter 2. When knurling diamond patterns on the end face of different products 8, the limit bolt inside the adjustment hole 3 can be loosened to adjust the height of the knurling cutter 2 to match different products 8. Then, the limit bolt can be tightened to lock the second mandrel 6 and the first mandrel 5.

[0033] 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.
