Description

Technical Field

[0001] This utility model belongs to the field of deep hole machining technology, and specifically relates to a precision welding housing bearing hole intermittent control tool. Background Technology

[0002] In the process of machining bearing holes in precision welded housings, the cutting tool is generally controlled intermittently to ensure stable cutting force and temperature, thus preventing fluctuations in the machining accuracy within the bearing hole.

[0003] Currently, Chinese utility model patent CN217858834U discloses a composite tool for machining bearing holes. In actual machining processes, factories process the inner diameter of bearing holes in different precision welded housings to varying sizes to accommodate different bearing models. However, existing tools typically require disassembling the original tool and installing a compatible tool to meet the needs of machining the bearing hole inner diameter. Since tools are generally bolted together, both disassembly and reassembly are cumbersome. Even if different tools are not needed for machining the bearing hole inner diameter, the tools themselves are prone to wear. After a period of use, severely worn tools need to be disassembled and replaced, reducing tool replacement efficiency and making tool disassembly and installation inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a precision welding housing bearing hole intermittent control tool, which has the advantages of being easy to disassemble and install the tool and eliminating the need for frequent tool replacement according to the machining requirements of the bearing hole inner diameter.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a precision welding housing bearing hole intermittent control tool, including a fixed platform, a rotating sleeve rotatably connected inside the fixed platform, a tool holder slidably inserted into one side of the rotating sleeve, a tool body of different models welded to the end of the tool holder away from the rotating sleeve, an insertion rod slidably connected to the surface of the rotating sleeve, a first spring fixedly connected to the rotating sleeve and bolted to the bottom of the insertion rod, the number and position of the insertion rods being consistent with the tool bodies, and an insertion hole for inserting the insertion rods being opened on the top of the fixed platform.

[0006] By adopting the above technical solution, various types of tool bodies are installed on one side of the rotating sleeve, and the number and position of the insert rods are consistent with those of the tool bodies. Therefore, rotating the rotating sleeve allows all types of tool bodies to be moved to the top side of the rotating sleeve and limited by the insert rods inserted into the insertion holes. Thus, when the bearing hole of the precision welded housing is fixed at the top of the rotating sleeve near the tool body, various types of tool bodies can be rotated and adjusted to be closer to the bearing hole for machining according to the inner diameter of the bearing hole, reducing the frequency of repeated disassembly and replacement of the tool bodies and improving practicality. By driving the screw to rotate, the screw pushes the conical slider to support the trapezoidal slide plate, thereby causing the abutment plate to fit against the inside of the rotating sleeve, using friction to fix the tool holder inside the fixed platform. This not only facilitates tool installation but also allows the tool holder to be removed from one side of the rotating sleeve simply by rotating the screw in the opposite direction, facilitating the repair or replacement of severely worn tool bodies.

[0007] The present invention is further configured such that: a screw is rotatably connected inside the tool holder; a hexagonal screw cylinder is threaded onto the surface of the screw and slidably connected to the tool holder; a conical slider is welded to the end of the hexagonal screw cylinder away from the screw; a first bevel gear is bolted to the end of the screw away from the hexagonal screw cylinder; a second bevel gear rotatably connected to the tool holder is meshed at the top of the first bevel gear; abutments are slidably connected to both sides of the surface of the tool holder; and a trapezoidal sliding plate is welded to the side of the abutment closest to the inside of the tool holder and slidably connected to the surface of the conical slider.

[0008] The above technical solution not only facilitates the installation of the cutting tool, but also allows the tool holder to be removed from the rotating sleeve side simply by rotating the screw in the opposite direction, making it convenient to repair or replace the severely worn tool body.

[0009] The present invention is further configured such that: a telescopic rod fixedly connected to the insertion rod is bolted inside the rotating sleeve at the bottom of the insertion rod, and the first spring is sleeved on the surface of the telescopic rod.

[0010] By adopting the above technical solution, the stability of the insertion rod extending and retracting on the surface of the rotating sleeve is improved, and shaking is reduced.

[0011] The present invention is further configured such that: a mounting screw is welded to the side of the fixing table away from the tool body, and a nut is threaded onto the surface of the mounting screw.

[0012] By using the above technical solution, the mounting screw is passed through the threaded hole of the machining table, and then the nut and the mounting screw are bolted together to fix the fixed table on one side of the machining table. The machine table drives the tool body to move intermittently back and forth in the bearing hole, thereby performing grinding on the bearing hole.

[0013] The present invention is further configured such that: the fixed platform is internally rotatably connected to a ball bearing that is slidably connected to the rotating sleeve.

[0014] By adopting the above technical solution, the frictional force of the rotating sleeve rotating inside the fixed platform is reduced, thereby improving rotational stability.

[0015] The present invention is further configured such that an anti-slip pad is adhered to the side of the abutment away from the trapezoidal sliding plate.

[0016] By adopting the above technical solution, the friction of the abutment surface is increased, thereby improving the stability of the abutment adhering to the inside of the tool holder.

[0017] The present invention is further configured such that: a second spring is symmetrically bolted to the side of the abutment plate near the trapezoidal sliding plate and fixedly connected to the knife holder.

[0018] Using the above technical solution, after the conical slider is driven to slide back to the screw, the contraction force of the second spring can be used to drive the stop plate to slide back quickly into the inside of the tool holder.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By mounting various types of tool bodies on one side of the rotating sleeve, and ensuring that the number and position of the insert rods are consistent with those of the tool bodies, rotating the rotating sleeve allows all types of tool bodies to be moved to the top side of the rotating sleeve and positioned within the insert holes by the insert rods. Therefore, when the bearing hole of the precision welded housing is fixed at the top of the rotating sleeve near the tool body, various types of tool bodies can be rotated and adjusted to be closer to the bearing hole for machining according to the inner diameter of the bearing hole. This reduces the frequency of repeated disassembly and replacement of the tool bodies, improving practicality.

[0021] 2. By rotating the screw, the screw pushes the conical slider to support the trapezoidal slide plate, thereby causing the abutment plate to fit against the inside of the rotating sleeve. Friction is used to fix the tool holder inside the fixed platform. This not only facilitates tool installation, but also allows the tool holder to be removed from one side of the rotating sleeve simply by rotating the screw in the opposite direction, making it convenient for repairing or replacing severely worn tool bodies.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1:

[0029] refer to Figure 1 , Figure 2 , Figure 3 A precision welding housing bearing hole intermittent control tool includes a fixed platform 1, a rotating sleeve 2 rotatably connected inside the fixed platform 1, a tool holder 3 slidably inserted into one side of the rotating sleeve 2, and tool bodies 4 of different models welded to the end of the tool holder 3 away from the rotating sleeve 2. Insert rods 6 are slidably connected to the surface of the rotating sleeve 2, and a first spring 5 fixedly connected to the rotating sleeve 2 is bolted to the bottom of the insert rods 6. The number and position of the insert rods 6 are consistent with those of the tool bodies 4. An insertion hole 7 is provided on the top of the fixed platform 1 for insertion of the insert rods 6. By installing multiple models of tool bodies 4 on one side of the rotating sleeve 2, and ensuring that the number and position of the insert rods 6 are consistent with those of the tool bodies 4, rotating the rotating sleeve 2 allows all models of tool bodies 4 to be moved to a position on the top side of the rotating sleeve 2 and limited by the insertion hole 7 of the insert rods 6. Therefore, when the bearing hole of the precision welding housing is fixed at the top of the rotating sleeve 2 near the tool body 4, the various models of tool bodies 4 can be rotated and adjusted to be closer to the bearing hole for machining according to the inner diameter of the bearing hole, reducing the frequency of repeated disassembly and replacement of the tool bodies 4 and improving practicality.

[0030] refer to Figure 3 Inside the rotating sleeve 2, at the bottom of the insert rod 6, is a telescopic rod 15 fixedly connected to the insert rod 6. A first spring 5 is sleeved on the surface of the telescopic rod 15. This improves the stability of the insert rod 6 as it extends and retracts on the surface of the rotating sleeve 2, reducing swaying.

[0031] refer to Figure 2A mounting screw 16 is welded to the side of the fixed table 1 away from the tool body 4, and a nut 17 is threaded onto the surface of the mounting screw 16. By passing the mounting screw 16 through the threaded hole of the machining table and then bolting the nut 17 and the mounting screw 16 together, the fixed table 1 is fixedly installed on one side of the machining table, causing the machine table to drive the tool body 4 to move intermittently back and forth in the bearing hole, thereby performing grinding on the bearing hole.

[0032] refer to Figure 2 The fixed platform 1 has a rotating ball bearing 18 that is slidably connected to the rotating sleeve 2. This reduces the friction of the rotating sleeve 2 rotating inside the fixed platform 1 and improves rotational stability.

[0033] Brief description of the usage process: Various types of tool bodies 4 are installed on one side of the tool holder 3, and the bearing hole of the precision welded housing is fixed at the top of the rotating sleeve 2 near the tool body 4. Then, by rotating the rotating sleeve 2 inside the fixed platform 1, the various types of tool bodies 4 can be moved to the top of the rotating sleeve 2. Next, the elastic force of the first spring 5 drives the insertion rod 6 to be inserted into the insertion hole 7, thereby limiting and fixing the rotating sleeve 2. This allows the various types of tool bodies 4 to be rotated and adjusted to approach the bearing hole according to the machining requirements of the bearing hole's inner diameter, thus enabling machining of the bearing hole's interior.

[0034] Example 2:

[0035] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A precision welded housing bearing hole intermittent control tool is disclosed. A screw 8 is rotatably connected inside the tool holder 3. A hexagonal screw cylinder 11, slidably connected to the tool holder 3, is threaded onto the surface of the screw 8. A conical slider 12 is welded to the end of the hexagonal screw cylinder 11 away from the screw 8. A first bevel gear 9 is bolted to the end of the screw 8 away from the hexagonal screw cylinder 11. A second bevel gear 10, rotatably connected to the tool holder 3, meshes with the top of the first bevel gear 9. A stop plate 13 is slidably connected to both sides of the tool holder 3. A trapezoidal sliding plate 14, slidably connected to the surface of the conical slider 12, is welded to the side of the stop plate 13 closest to the inside of the tool holder 3. By rotating the screw 8, the screw 8 pushes the conical slider 12 to support the trapezoidal sliding plate 14, thereby causing the stop plate 13 to fit against the inside of the rotating sleeve 2. Friction is used to fix the tool holder 3 inside the fixed platform 1. This not only facilitates tool installation but also allows the tool holder 3 to be removed from one side of the rotating sleeve 2 simply by rotating the screw 8 in the opposite direction, facilitating the repair or replacement of the severely worn tool body 4.

[0036] refer to Figure 3An anti-slip pad 20 is adhered to the side of the abutment plate 13 away from the trapezoidal sliding plate 14. This increases the friction on the surface of the abutment plate 13 and improves the stability of the abutment plate 13 when it is attached to the inside of the knife holder 3.

[0037] refer to Figure 3 A second spring 19, which is fixedly connected to the cutter holder 3, is symmetrically bolted to the side of the abutment plate 13 near the trapezoidal slide plate 14. After the conical slider 12 slides back to the screw 8, the contraction force of the second spring 19 can be used to drive the abutment plate 13 to slide back quickly into the interior of the cutter holder 3.

[0038] Brief description of the usage process: The tool holder 3 is inserted into the rotating sleeve 2, and then the second bevel gear 10 is rotated to mesh with the first bevel gear 9, thereby driving the screw 8 to rotate. Then, the screw 8 engages with the hexagonal screw cylinder 11, causing the hexagonal screw cylinder 11 to drive the conical slider 12 to slide away from the screw 8 inside the tool holder 3. This causes the conical slider 12 to push the trapezoidal sliding plate 14 to slide, causing the abutment 13 to fit against the inside of the rotating sleeve 2. This uses friction to secure the tool holder 3, and the threaded engagement friction between the screw 8 and the hexagonal screw cylinder 11 provides self-locking and limiting, thus quickly installing the tool body 4 onto one side of the rotating sleeve 2. Similarly, disassembling the tool body 4 only requires rotating the second bevel gear 10 in the opposite direction.

[0039] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
