Description

Technical Field

[0001] This utility model relates to the field of engine cylinder block machining technology, specifically to a drilling and reaming integrated tool for engine cylinder blocks. Background Technology

[0002] An integrated drilling and reaming tool for engine blocks is a tool that integrates drilling and reaming functions into one, allowing the drilling and reaming processes of engine block holes to be completed in a single machining operation.

[0003] However, existing integrated drilling and reaming tools are usually fixed connections, and after long-term use, the tools are prone to wear and need to be replaced as a whole, resulting in high tool usage costs.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an integrated drilling and reaming tool for engine cylinder blocks. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated drilling and reaming tool for engine cylinder blocks to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drill-reamer integrated tool for engine cylinder blocks, comprising a drill bit and a reinforcing assembly. The drill bit has a tool mounting groove on its side, and a reamer is disposed inside the tool mounting groove. The reamer has a fixing hole on its side, and a rod is installed at the lower end of the reamer. The reinforcing assembly for mounting reinforcement is disposed at the lower end inside the tool mounting groove. The reinforcing assembly includes a reinforcing plate, a limiting hole, a spring, and an inner groove. A limiting hole is provided in the middle of the upper part of the reinforcing plate, and a spring is installed at the lower end of the reinforcing plate. An inner groove is provided on the outside of the spring.

[0007] Furthermore, the tool slots are arranged in a ring around the center point of the drill bit, and the tool slots and the drill bit are an integrated structure.

[0008] Furthermore, the reinforcing plate and the limiting hole are an integrated structure, and the number of reinforcing plates and the number of tool slots are the same.

[0009] Furthermore, the side of the tool mounting groove is provided with an external fixing hole, and a fixing screw is provided inside the external fixing hole.

[0010] Furthermore, the drill bit has an upper mounting hole in the middle of its upper end and a lower mounting hole in the middle of its lower end.

[0011] Furthermore, the inner wall of the lower mounting hole is provided with a connecting hole, and an auxiliary component for auxiliary installation is provided inside the lower mounting hole.

[0012] Furthermore, the auxiliary component includes a mounting block and an assembly rod, with the assembly rod connected to the end of the mounting block.

[0013] Furthermore, the diameter of the mounting block is consistent with the inner diameter of the lower mounting hole, and the mounting block and the assembly rod are fixedly connected.

[0014] This utility model provides a drilling and reaming tool for engine cylinder blocks, which has the following advantages:

[0015] 1. This utility model uses a tool mounting groove for quick positioning and installation of reamers. The reamer is detachable and replaceable. After the cutting edge of the reamer wears, the tool can continue to be used by replacing the blade, reducing the cost of tool resharpening and replacement, improving tool life and processing efficiency. When the reinforcing plate is installed, it is pressed down to compress the spring. The spring's rebound force after compression plays a pushing and limiting role on the installed reamer, increasing the ease of installation and facilitating subsequent fixation. The limiting hole allows the bottom insert rod of the reamer to be pre-inserted and positioned during installation, increasing the accuracy of reamer installation.

[0016] 2. This utility model uses the fixing hole and the external fixing hole to fix the reamer under the action of the fixing screw. The upper mounting hole and the lower mounting hole can be used to install auxiliary components, increasing the fixing position of the drill bit. The mounting block is connected by bolts and connecting holes, so the assembly rod can be installed on the side of the drill bit. Changing the installation position is simple.

[0023] like Figure 1 and Figure 2 As shown, a drill-reamer integrated tool for engine cylinder blocks includes a drill bit 1 and a reinforcing assembly 5. The drill bit 1 has a tool mounting groove 2 on its side, which is used for the quick mounting and positioning of a reamer 3. The reamer 3 is housed inside the tool mounting groove 2. The reamer 3 is removable and replaceable; after the cutting edge of the reamer 3 wears, the tool can continue to be used by replacing the insert, reducing the cost of tool resharpening and replacement, and improving tool life and processing efficiency. The reamer 3 has a fixing hole 4 on its side. The fixing hole 4 and the external fixing hole 6 are aligned and, under the action of the fixing screw 7, the reamer is reamed. The cutter 3 is fixedly installed, and the lower end of the reamer 3 is equipped with a rod 12. The cutter slots 2 are arranged in a ring around the center point of the drill bit 1. The cutter slots 2 and the drill bit 1 are an integrated structure. The reinforcing plate 501 and the limiting hole 502 are an integrated structure. The number of reinforcing plates 501 and cutter slots 2 are the same. The side of the cutter slot 2 is provided with an external fixing hole 6. The internal part of the external fixing hole 6 is provided with a fixing screw 7. The upper part of the drill bit 1 is provided with an upper mounting hole 8. Both the upper mounting hole 8 and the lower mounting hole 9 can be used for the installation of auxiliary components 11 to increase the fixed position of the drill bit 1.

[0024] like Figure 3 As shown, the reinforcement component 5 for installation and reinforcement is located at the lower end of the mounting slot 2. The reinforcement component 5 includes a reinforcement plate 501, a limiting hole 502, a spring 503, and an inner groove 504. The limiting hole 502 is opened in the middle of the upper end of the reinforcement plate 501. When the reamer 3 is installed, the reinforcement plate 501 is pressed down to compress the spring 503. The limiting hole 502 allows the bottom insertion rod 12 of the reamer 3 to be pre-inserted and positioned during installation, increasing the accuracy of the reamer 3 installation. The spring 503 is installed at the lower end of the reinforcement plate 501. The spring 503's rebound force after being compressed plays a pushing and limiting role on the installed reamer 3, increasing the ease of installation and facilitating subsequent fixation. The inner groove 504 is provided on the outside of the spring 503 for the concealed installation of the spring 503.

[0025] like Figure 4As shown, a lower mounting hole 9 is provided in the middle of the lower end of the drill bit 1. A connecting hole 10 is provided in the inner wall of the lower mounting hole 9.

The end of the mounting block 1101 is connected to the assembly rod 1102. The mounting block 1101 is connected to the connecting hole 10 by bolts, so that the assembly rod 1102 can be installed on the side of the drill bit 1. Changing the installation position is simple. The diameter of the mounting block 1101 is consistent with the inner diameter of the lower mounting hole 9, and the mounting block 1101 and the assembly rod 1102 are fixedly connected.

[0026] In summary, this engine block uses a drill-reamer combo tool, firstly based on... Figures 1-4 The structure shown in the diagram allows for quick installation of the reamer 3 by aligning the insert rod 12 at the lower end of the reamer 3 with the limiting hole 502 during installation. This increases the accuracy of subsequent installation of the reamer 3. The reamer 3 is then installed into the insert groove 2. During installation, the reinforcing plate 501 is pressed down, compressing the spring 503. The spring 503's rebound force after being compressed acts as a pusher and limiter on the installed reamer 3, increasing installation convenience and facilitating subsequent fixation. The detachable and replaceable reamer 3 can continue to be used after the cutting edge of the reamer 3 wears down by replacing the insert, reducing the cost of tool resharpening and replacement, and improving tool life and processing efficiency. The fixing screw 7 is then passed through the fixing hole 4 and the external fixing hole 6 to fix the reamer 3 in place. During use, the mounting block 1101 is connected to the connecting hole 10 via bolts, allowing the assembly rod 1102 to be installed on the side of the drill bit 1.
