Description

Technical Field

[0001] This utility model belongs to the field of tool cutting and fixing technology, specifically relating to a tool cutting and fixing device with enhanced rigidity. Background Technology

[0002] The enhanced rigidity tool holder is a device used to firmly fix the tool disc to the tool disc, thereby improving the overall rigidity and stability of the tool disc and ensuring that the tool disc can perform cutting operations stably and efficiently.

[0003] In existing cutting tool processing, when fixing the position using a fixing device, the only method is to operate the module and screw. The axial movement of the screw generates pressure, which drives the module to apply pressure evenly to the cutting tool, thus firmly clamping the cutting tool at a specific position in the metal fixture. However, this method only clamps the cutting tool laterally and cannot position it. When there is a deviation in the installation position of the cutting tool, it causes instability in cutting due to positioning errors. Therefore, this utility model proposes a cutting tool fixing device with enhanced rigidity. Utility Model Content

[0004] The purpose of this utility model is to provide a rigid tool holder to solve the problem mentioned in the background art that, after the tool is fixed by the holder, it is convenient for subsequent cutting operations. However, if the tool is only fixed laterally, the cutting effect is affected when there is a deviation in the clamping position of the tool.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rigid tool blade fixing device, comprising clamps symmetrically arranged on a base, and tool blades arranged between the symmetrically arranged clamps;

[0006] The cutting tool consists of a lower cutting body and an upper cutting blade. The upper cutting blade is fixed to the bottom end of the lower cutting body. The top end of the upper cutting blade is at the same level as the top end of the clamp. A central hole is provided on the inner side of the upper cutting blade and the inner side of the lower cutting body. A positioning mechanism is provided between the symmetrically arranged clamps at the bottom end of the cutting tool, and the top end of the positioning mechanism extends through to the inner side of the central hole.

[0007] The positioning mechanism consists of a positioning pin, a silicone seat, multiple limiting components, and an installation component. The installation component is located at the bottom end of the positioning pin, the silicone seat is sleeved and fixed to the top surface of the positioning pin, and the multiple limiting components are located between the silicone seat and the positioning pin.

[0008] Preferably, the top of the silicone seat has an inclined structure, and the top of the silicone seat, the top of the positioning pin, and the top of the lower blade are on the same horizontal plane.

[0009] Preferably, the positioning pin is a hollow cylindrical structure.

[0010] Preferably, the limiting component consists of a limiting groove and a limiting block. The limiting groove is formed on the side surface of the positioning pin, the limiting block is fixed to the inner side of the limiting groove, and the outer side of the limiting block is fixed to the inner side of the silicone seat.

[0011] Preferably, the mounting assembly consists of a mounting base, a locking assembly, and symmetrically arranged through-threaded rods. The locking assembly consists of a slot and a block. The slot is located at the bottom end of the positioning pin, and the block is fixed to the top end of the mounting base. The slot and the block are in a locked state. The symmetrically arranged through-threaded rods are located on both sides of the positioning pin, and the ends of the through-threaded rods penetrate the positioning pin into the interior of the block.

[0012] Preferably, the clamps are symmetrically arranged with modules on both sides, and a screw runs through the inner side of the module, with the end of the screw pressing against the side of the clamp.

[0013] Preferably, the module consists of an inner metal block, a stiffening plate layer, and a silicone sleeve. The stiffening plate layer is wrapped and fixed to the outside of the inner metal block, and the silicone sleeve is wrapped and fixed to the outside of the stiffening plate layer.

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

[0015] By designing a positioning mechanism, the previous method of fixing the tool disc in the cutting process using a fixing device, which only laterally clamped and positioned the tool disc, was improved. This method was insufficient for proper tool disc positioning, and when there was a deviation in the tool disc's installation position, the positioning error caused instability in the cutting process. By incorporating a positioning mechanism into the fixing device, the tool disc is positioned by the positioning mechanism before being clamped, which enhances rigidity and minimizes the deformation of the fixing device under cutting forces. This ensures accurate tool disc installation and precise positioning, ensuring that the cutting equipment and tool disc are in the correct positions, guaranteeing that the tool disc is always in a stable working position and ensuring the dimensional accuracy of the cutting process.

[0022] 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.

[0023] Example 1

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: a rigid tool blade fixing device, including clamps 2 symmetrically arranged on a base 1, and tool blades 5 arranged between the clamps 2 symmetrically arranged;

[0025] The cutting tool 5 consists of a lower cutting tool body 51 and an upper cutting tool 52. The upper cutting tool 52 is fixed to the bottom end of the lower cutting tool body 51. The top end of the upper cutting tool 52 is at the same level as the top end of the clamp 2. A central hole is provided on the inner side of the upper cutting tool 52 and the inner side of the lower cutting tool body 51. A positioning mechanism 6 is provided between the symmetrically arranged clamps 2 and at the bottom end of the cutting tool 5. The top end of the positioning mechanism 6 extends through to the inner side of the central hole.

[0026] The positioning mechanism 6 consists of a positioning pin 61, a silicone seat 62, multiple limiting components 63, and a mounting component 64. The mounting component 64 is located at the bottom end of the positioning pin 61, the silicone seat 62 is sleeved and fixed to the top surface of the positioning pin 61, and the multiple limiting components 63 are located between the silicone seat 62 and the positioning pin 61. This positioning mechanism 6 improves upon the previous method where, during the cutting process of the cutting tool 5, the tool 5 was only laterally clamped and positioned by the fixing device, which was insufficient for proper positioning. Furthermore, when there was a deviation in the installation position of the cutting tool 5, the positioning error caused instability in the cutting process. By incorporating a positioning mechanism 6 into the fixing device, the cutting tool 5 is positioned by the positioning mechanism 6 before being clamped, ensuring accurate installation of the cutting tool. Precise positioning ensures that the cutting equipment and the cutting tool 5 are in the correct positions, guaranteeing the dimensional accuracy of the cutting process. The top of the silicone seat 62 is inclined, which increases the ease with which the positioning mechanism 6 passes through the central hole of the cutting tool 5. The top of the silicone seat 62, the top of the positioning pin 61, and the top of the lower tool body 51 are on the same horizontal plane, ensuring that the cutting process of the cutting tool 5 is not affected. The positioning pin 61 is a hollow cylinder. The structure includes a limiting component 63 consisting of a limiting groove 631 and a limiting block 632. The limiting groove 631 is formed on the side surface of the positioning pin 61, and the limiting block 632 is fixed to the inner side of the limiting groove 631. The outer side of the limiting block 632 is fixed to the inner side of the silicone seat 62. The limiting component 63 ensures the stability between the positioning pin 61 and the silicone seat 62. The mounting component 64 consists of a mounting base 641, a locking component 642, and symmetrically arranged through threaded rods 643. The locking component 642 consists of a locking groove 6421 and a locking block 6422. The locking groove 6421 is formed at the bottom end of the positioning pin 61, and the locking block 6422 is fixed to the mounting base 641. At the top of 41, the slot 6421 and the block 6422 are engaged. Symmetrically arranged through threaded rods 643 are arranged on both sides of the positioning pin 61, and the end of the through threaded rod 643 passes through the positioning pin 61 into the interior of the block 6422. The positioning pin 61 can be disassembled and replaced by the mounting component 64. Modules 3 are arranged on both sides of the symmetrically arranged clamp 2, and screws 4 pass through the inner side of the module 3. The end of the screw 4 presses against the side of the clamp 2. The axial movement of the screw 4 generates pressure, and the screw 4 drives the module 3 to apply pressure evenly to the tool piece 5, so that the tool piece 5 is firmly clamped in a specific position of the metal clamp.

[0027] Example 2

[0028] Please see Figures 1 to 5 This utility model provides a technical solution: a rigid tool blade fixing device, including clamps 2 symmetrically arranged on a base 1, and tool blades 5 arranged between the clamps 2 symmetrically arranged;

[0029] The cutting tool 5 consists of a lower cutting tool body 51 and an upper cutting tool 52. The upper cutting tool 52 is fixed to the bottom end of the lower cutting tool body 51. The top end of the upper cutting tool 52 is at the same level as the top end of the clamp 2. A central hole is provided on the inner side of the upper cutting tool 52 and the inner side of the lower cutting tool body 51. A positioning mechanism 6 is provided between the symmetrically arranged clamps 2 and at the bottom end of the cutting tool 5. The top end of the positioning mechanism 6 extends through to the inner side of the central hole.

[0030] The positioning mechanism 6 consists of a positioning pin 61, a silicone seat 62, multiple limiting components 63, and a mounting component 64. The mounting component 64 is located at the bottom end of the positioning pin 61, and the silicone seat 62 is sleeved and fixed to the top surface of the positioning pin 61. The multiple limiting components 63 are located between the silicone seat 62 and the positioning pin 61. The designed positioning mechanism 6 improves upon the previous method where the tool piece 5 was only laterally clamped and positioned by the fixing device during cutting, which failed to accurately position the tool piece 5. When there was a deviation in the installation position of the tool piece 5, the positioning error caused instability in the cutting process. By incorporating the positioning mechanism 6 into the fixing device, the tool piece 5 is positioned by the positioning mechanism 6 before being clamped, ensuring accurate installation. Precise positioning ensures that the cutting equipment and the tool piece 5 are in the correct positions, guaranteeing the dimensional accuracy of the tool piece 5 during cutting. The top of the silicone seat 62 is inclined, and the top of the silicone seat 62, the top of the positioning pin 61, and the top of the lower tool body 51 are on the same horizontal plane. 61 is a hollow cylindrical structure. The limiting component 63 consists of a limiting groove 631 and a limiting block 632. The limiting groove 631 is formed on the side surface of the positioning pin 61. When the top of the positioning mechanism 6 passes through the center hole of the cutter piece 5, the inclined structure at the top edge of the silicone seat 62 increases the ease of engagement between the two. When engaged with the positioning mechanism 6 through the center hole, the silicone seat 62 is squeezed, increasing the stability of the cutter piece 5 after positioning. The limiting block 632 is fixed inside the limiting groove 631, and the outer side of the limiting block 632 is attached to the inner side of the silicone seat 62. The side-fixed mounting assembly 64 consists of a mounting base 641, a locking assembly 642, and symmetrically arranged through threaded rods 643. The locking assembly 642 consists of a slot 6421 and a block 6422. The slot 6421 is located at the bottom end of the positioning pin 61, and the block 6422 is fixed to the top end of the mounting base 641. The slot 6421 and the block 6422 are in a locked state. The symmetrically arranged through threaded rods 643 are located on both sides of the positioning pin 61, and the ends of the through threaded rods 643 penetrate the positioning pin 61 to the interior of the block 6422.

[0031] The clamps 2 are symmetrically arranged with modules 3 on both sides, and screws 4 pass through the inner side of the modules 3. The ends of the screws 4 press against the sides of the clamps 2, and pressure is generated by the axial movement of the screws 4.

[0032] In this embodiment, preferably, module 3 consists of an inner metal block 31, a rib layer 32, and a silicone sleeve 33. The rib layer 32 is wrapped and fixed to the outside of the inner metal block 31, and the silicone sleeve 33 is wrapped and fixed to the outside of the rib layer 32. Module 3 can buffer the clamping pressure on the cutting tool 5, preventing the cutting tool 5 from being damaged due to excessive local force. At the same time, it increases the friction between the cutting tool and the cutting tool, ensuring that the cutting tool does not shift or loosen under the action of cutting force, thereby performing cutting operations stably.

[0033] The working principle and usage process of this utility model are as follows: When cutting the cutting tool 5, the cutting tool 5 is first fixed by the fixing device. The cutting tool 5 is initially placed between the symmetrically arranged clamps 2, and the top of the positioning mechanism 6 passes through the central hole in the middle of the cutting tool 5 to position the cutting tool 5, so that the cutting tool 5 is correctly installed in the position, reducing the cutting instability caused by positioning errors. Then, the screw 4 is rotated, and the axial movement of the screw 4 generates pressure. The screw 4 drives the module 3 to apply the pressure evenly to the cutting tool 5, so that the cutting tool 5 is firmly clamped in a specific position of the metal clamp. The module 3 can buffer the pressure to prevent the cutting tool 5 from being damaged due to excessive local force, and at the same time increase the friction between the module and the cutting tool to ensure that the cutting tool does not shift or loosen under the action of cutting force, thereby performing cutting operations stably.

[0034] 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.
