Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a replaceable alloy blade head device. Background Technology

[0002] Carbide inserts are core components of cutting tools made of composite materials such as cemented carbide. They are commonly used in metal cutting and machining. Combining the properties of different metals or non-metals, they possess high hardness, wear resistance, and impact resistance. They can be mounted on the tool body to achieve efficient cutting and are adaptable to a variety of machining materials. They are key components for improving the accuracy and efficiency of machining.

[0003] According to the document with the publication number "CN216938571U", "This utility model discloses an alloy blade and a drill bit with the alloy blade fixed thereon, which includes a main body, a tip on the top of the main body, a front side and a rear side, and three or four limiting protrusions on the main body, which are located on the left and right ends of the front side and the left and right ends of the rear side respectively." When in use, this utility model is firmly fixed, has a good positioning effect, and is not easy to slip.

[0004] However, in existing cutting tool technology, the traditional connection between the blade and the cutting head is mostly a simple bolt fixation or direct plug-in. When making heavy cuts, the concentrated force can easily cause severe wear at the contact point between the handle and the cutting head, thus affecting the overall service life and cutting accuracy of the tool. Moreover, in complex cutting environments, the blade is prone to shifting due to uneven force, which not only reduces the cutting effect but may also pose a safety hazard. In addition, the stability of traditional connection structures needs to be improved, especially when subjected to rotational forces, which can easily lead to slippage and cause the tool to malfunction.

[0005] Therefore, we provide a replaceable alloy blade tip device to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A replaceable alloy blade tip device includes a tip holder with a through hole in the center.

A fixing bolt hole is provided in the center of each tip groove, and limit holes are provided on both sides of the fixing bolt hole. A lower rubber pad is mounted inside each tip groove, and a blade handle is mounted above each lower rubber pad. A force-bearing rib is provided on the surface of each blade handle. A blade body is welded to the outer side of the blade handle, and an upper rubber pad is mounted above the blade handle. A clamping plate is mounted on the upper side of the tip holder.

[0007] As a further description of the above technical solution: The latch is connected to the through hole and the slot by a slot, and the latch fits tightly to the through hole and the slot.

[0008] As a further description of the above technical solution: A washer is connected to the inner groove on the lower side of the cutter head seat. A connecting screw passes through the middle of the washer. The connecting screw passes through the washer and the through hole and is threadedly connected to the connecting rod.

[0009] As a further description of the above technical solution: The handle and the cutter head groove are fitted together. The handle and the cutter head groove are arranged in three groups at equal distances about the cutter head seat. The handle has a fan-shaped structure. The handle and the cutter head groove are fixed together by bolts.

[0010] As a further description of the above technical solution: The force-bearing bolt and the limiting hole are connected by a slot. The force-bearing bolt has a triangular structure and penetrates the entire structure. The tool holder and the tool head groove are limited by the force-bearing bolt and the limiting hole.

[0011] As a further description of the above technical solution: The lower rubber pad and the cutter head groove are connected by a slot, and the lower rubber pad and the upper rubber pad are arranged in a one-to-one correspondence. The cutter handle is located between the lower rubber pad and the upper rubber pad.

[0012] As a further description of the above technical solution: The clamping plate has the same diameter as the cutter head holder, and the clamping plate fixes the cutter head holder through a connecting rod and a connecting screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a blade mounting assembly to embed the blade handle into the blade head groove. Bolts are then tightened through the fixing bolt holes to ensure a tight fixation between the blade handle and the blade head seat. The blade handle and blade head groove are fan-shaped, which effectively disperses the pressure generated during cutting, reduces blade handle wear, and extends service life. The blade handle's movement is effectively limited by a force-bearing bolt passing through a limiting hole. The rigid limiting effect of the force-bearing bolt enhances the stability of the blade handle, preventing the blade body from shifting due to force during cutting. After the blade handle is embedded in the blade head groove, the lower and upper rubber pads clamp it, ensuring uniform force distribution and reducing vibration during cutting.

[0014] 2. This utility model utilizes a bolt, a through hole, and a connecting screw. When needed, the bolt is inserted into the through hole, and the protrusions on both sides of the bolt embed into the slot. This improves the connection stability between the cutter head seat and the connecting rod during cutting operations. Compared to bolt connections, this ensures connection strength and reduces slippage due to external forces during rotation. The connecting rod is then placed under the cutter head seat, and the connecting screw is used to connect the cutter head seat to the bolt and the connecting rod. This, combined with the bolt engaging the through hole, provides a double fixing effect, ensuring the stability and durability of the connection. The clamping plate is directly fitted onto the outside of the cutter head seat, and the tightening of the connecting rod and the connecting screw ensures that the clamping plate and the cutter head seat form a tight whole, improving the overall structural stability.

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.

[0018] Please see Figure 1-5 As shown, this utility model provides a technical solution: a replaceable alloy blade head device, including a blade head seat 1, a through hole 2 in the middle of the blade head seat 1, slots 3 at both ends of the inner side of the through hole 2, a connecting rod 4 installed on the upper side of the through hole 2, a retaining bolt 5 connected to the lower side of the connecting rod 4, and a blade mounting assembly 8 provided on the inner side of the blade head seat 1. The blade mounting assembly 8 includes blade grooves 801 all disposed on the inner wall of the blade head seat 1. Each of the components has a fixing bolt hole 802 in the middle, and limit holes 803 on both the left and right sides of the fixing bolt hole 802. A lower rubber pad 804 is installed on the inner side of the cutter head groove 801, and a cutter shank 805 is installed on the upper side of the lower rubber pad 804. A force-bearing rib bolt 806 is provided on the surface of the cutter shank 805. A blade body 807 is welded to the outer side of the cutter shank 805, and an upper rubber pad 808 is installed on the upper side of the cutter shank 805. A clamping plate 809 is installed on the upper side of the cutter head seat 1.

[0019] Furthermore, the bolt 5 is connected to the through hole 2 and the slot 3 by a slot, and the bolt 5 fits tightly with the through hole 2 and the slot 3. When needed, the bolt 5 is inserted into the through hole 2, and the protrusions on the left and right sides of the bolt 5 will be embedded in the slot 3. In this way, when the blade body 807 is performing cutting operations, the connection stability between the blade head seat 1 and the connecting rod 4 can be improved. Compared with the bolt connection, it not only ensures the connection strength, but also reduces the problem of slippage due to external force during rotation.

[0020] Furthermore, a washer 6 is connected to the inner groove on the lower side of the cutter head holder 1. A connecting screw 7 passes through the middle of the washer 6. The connecting screw 7 passes through the washer 6 and the through hole 2 and the connecting rod 4 and the connecting rod 4 are threaded together. When needed, the connecting rod 4 is placed under the cutter head holder 1, and then the connecting screw 7 passes through the cutter head holder 1 and the bolt 5 and the connecting rod 4. In this way, the bolt 5 is inserted into the through hole 2, which plays a double fixing role and ensures the stability and durability of the connection.

[0021] Furthermore, the handle 805 and the cutter head groove 801 are fitted together. The handle 805 and the cutter head groove 801 are arranged in three groups at equal distances about the cutter head seat 1. The handle 805 has a fan-shaped structure. The handle 805 and the cutter head groove 801 are fixed together by bolts. When needed, the handle 805 is inserted into the cutter head groove 801 and the bolts are tightened through the fixing bolt holes 802 to ensure that the handle 805 and the cutter head seat 1 are tightly fixed. The fan-shaped structure of the handle 805 and the cutter head groove 801 can effectively distribute the pressure generated during cutting, reduce the wear of the handle 805, and extend its service life.

[0022] Furthermore, the force-bearing bolt 806 and the limiting hole 803 are connected by a slot. The force-bearing bolt 806 has a triangular structure and penetrates the entire structure. The tool holder 805 and the tool head groove 801 are limited by the force-bearing bolt 806 and the limiting hole 803. When needed, the tool holder 805 passes through the limiting hole 803 via the force-bearing bolt 806, which can effectively limit the movement range of the tool holder 805. Moreover, the rigid limitation of the force-bearing bolt 806 enhances the stability of the tool holder 805 and prevents the blade body 807 from shifting due to force during the cutting process.

[0023] Furthermore, the lower rubber pad 804 and the cutter head groove 801 are connected by a slot, and the lower rubber pad 804 and the upper rubber pad 808 are set one-to-one. The cutter handle 805 is located between the lower rubber pad 804 and the upper rubber pad 808. When needed, the cutter handle 805 is inserted into the cutter head groove 801, and the lower rubber pad 804 and the upper rubber pad 808 clamp it to ensure that the cutter handle 805 is subjected to uniform force during the cutting process and to reduce vibration.

[0024] Furthermore, the clamping plate 809 has the same diameter as the cutter head holder 1. The clamping plate 809 is fixed to the cutter head holder 1 by the connecting rod 4 and the connecting screw 7. When needed, the clamping plate 809 is directly fitted into the cutter head holder 1, and the clamping plate 809 and the cutter head holder 1 are tightly integrated by the fastening of the connecting rod 4 and the connecting screw 7, thereby improving the overall structural stability.

[0025] Working principle: When needed, first insert the lower rubber pad 804 into the cutter head groove 801 on the surface of the cutter head seat 1, then insert the cutter shank 805 into the cutter head groove 801, and then cover the cutter shank 805 with the upper rubber pad 808. The cutter shank 805 is connected in series through the limiting hole 803 via the force-bearing bolt 806. After all three sets of cutter shanks 805 are installed, the clamping plate 809 is fitted into the cutter head seat 1, and then the external bolt is used to pass through the fixing bolt hole 802 to limit the three sets of cutter shanks 805. Finally, the retaining bolt 5 at the end of the connecting rod 4 is inserted into the through hole 2, and the protrusions at both ends of the retaining bolt 5 are embedded in the slot 3. Then, the washer 6 is inserted into the bottom of the cutter head seat 1, and the connecting screw 7 passes through the washer 6 and connects to the bottom of the cutter head seat 1, and is threaded to the connecting rod 4 for overall fixation. This completes the use process of a replaceable alloy blade cutter head device.
