Coated tool assembly suitable for different reaming shapes

Abstract

This invention relates to the field of reaming tool assembly technology, and discloses a coating tool assembly suitable for different reaming shapes. The assembly includes a milling machine body, an adjustment component, a fixing ring, a first electric actuator, a sliding ring, a connecting frame, a rotating shaft, a second motor, a mounting box, and a reaming cutting edge. In this invention, when processing specific tapered holes and inverted tapered holes, only the forward or reverse rotation of the second motor needs to be controlled to adjust the rotation angle to adapt to different tapered holes. Furthermore, the reaming cutting edge can extend and retract under the drive of the second electric actuator, thereby changing the diameter of the reamed hole at any time to meet various processing requirements. Simultaneously with reaming, a chip removal component is activated, and its internal vacuum cleaner sucks the debris generated during reaming into a storage cylinder for easy cleaning by subsequent personnel, preventing blockage of the hole and accelerating wear on the reaming cutting edge.

Description

Technical Field

[0001] This invention relates to the field of reaming tool assembly technology, and in particular to a coated tool assembly suitable for different reaming shapes. Background Technology

[0002] Hole-reaming coated tools are tools that have undergone special coating treatment and are used for hole-reaming operations in machining. The coating can improve the hardness and wear resistance of the tool, enabling it to withstand higher cutting forces and cutting temperatures during the cutting process, thereby improving cutting performance. It can also reduce the direct contact between the tool and the workpiece material, reduce the wear rate, and extend the tool's service life.

[0003] Traditional hole-reaming coated tools can reduce wear rate, extend tool life and improve cutting performance. However, in the process of machining workpieces, it is sometimes necessary to machine holes of various diameters, and some special holes require changes in the cutting angle or position of the tool (such as tapered holes and inverted tapered holes). This requires the operator to constantly change the tool angle and replace the tool with a suitable size according to the machining requirements, which brings higher difficulty to the machining work and affects work efficiency. Summary of the Invention

[0004] In order to solve the problems existing in the background art, the present invention provides a coated tool assembly that can change the angle and position of the reaming tool.

[0005] To address the problems in the prior art, this invention provides a coating tool assembly suitable for different hole-reaming shapes, comprising a main body, an adjustment component mounted on the outer wall of the main body, and an internal component including a fixing ring, first electric actuators, a sliding ring, a connecting frame, a rotating shaft, and a second motor. The fixing ring is fixedly mounted on the outer wall of the main body, and the bases of multiple sets of first electric actuators are fixedly connected to the lower end of the fixing ring. The sliding ring is slidably connected to the outer wall of the connecting cylinder, and the upper end of the sliding ring is fixedly connected to the output shaft of multiple sets of first electric actuators. Multiple sets of connecting frames are fixedly mounted on the outer wall of the sliding ring, and the rotating shaft is rotatably connected inside the connecting frame. The output shaft of the second motor is fixedly connected to one end of the rotating shaft, and the second motor is fixedly mounted on one side of the connecting frame. One end of the mounting box is fixedly connected to the outer wall of the rotating shaft, and the hole-reaming cutting edge is slidably connected inside the mounting box.

[0006] Specifically, the maximum angle that the second motor can drive the rotating shaft to rotate is the forward rotation degree and the reverse rotation degree.

[0007] Specifically, the reaming tool assembly is fixedly installed on the outer wall of the rotating shaft. The interior of the reaming tool assembly includes a mounting box, reaming blades, slide grooves, a fixing frame, and a second electric actuator. The mounting box has two sets of slide grooves inside, and a set of fixing frames is slidably connected in the slide grooves. A set of reaming blades is placed inside the fixing frame. The reaming blades and the fixing frame are fixedly connected by bolts. The lower end of the fixing frame is fixedly connected to the output shaft of the second electric actuator, which is fixedly installed inside the mounting box.

[0008] Specifically, a chip removal assembly is fixedly installed inside the main body of the equipment. The chip removal assembly includes a barrier cover, a drill bit, a suction box, an installation pipe, a connecting pipe, a vacuum cleaner, an air outlet pipe, a storage cylinder, and a first motor. The barrier cover is fixedly installed at the lower end of the tool, and multiple slots are opened on the outer wall of the barrier cover.

[0009] Specifically, the first motor is fixedly installed inside the top of the connecting cylinder, and the output shaft of the first motor is fixedly connected to the upper end of the storage cylinder. A set of vacuum cleaners is fixedly connected to the lower end of the storage cylinder. The vacuum cleaners are rotatably connected to the bottom plate inside the connecting cylinder. A set of air outlet pipes is fixedly connected to both sides of the vacuum cleaners. There is a gap between the air outlet pipes and the connecting cylinder. When the air outlet pipes rotate, the air outlet at the upper end of the air outlet pipes coincides with the air outlet at the upper end of the connecting cylinder. The angle at which the first motor drives the storage cylinder to rotate is positive.

[0010] Specifically, the lower end of the vacuum cleaner is fixedly connected to one end of the connecting tube, the other end of the connecting tube is fixedly connected to one end of the mounting tube, the connecting tube is rotatably connected to the inside of the cutter, and multiple suction boxes are fixedly connected to the outer wall of the mounting tube. The suction boxes are fixedly installed inside the drill bit, and the drill bit and the mounting tube are fixedly connected.

[0011] Specifically, a set of connecting cylinders is fixedly installed at the lower end of the main body of the equipment, and a set of cutting tools is fixedly installed at the lower end of the connecting cylinders.

[0012] The beneficial effects of this invention are:

[0013] The positioning component in this invention can change the cutting angle of the reaming tool assembly to adapt to various types of tapered holes and inverted tapered holes, eliminating the need for manual adjustment by operators and effectively improving work efficiency.

[0014] The reaming tool assembly of the present invention has an internal reaming blade whose extension length can be changed by controlling the extension and retraction of the second electric actuator, thereby processing holes of different diameters.

[0015] In this invention, the chip removal component can suck the chips generated during processing into the storage cylinder when using the positioning component and the hole reaming tool component, thereby facilitating subsequent processing and effectively preventing chips from clogging the holes and affecting the hole reaming efficiency.

Detailed Implementation

[0025] To make the technical methods, creative features, objectives, and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 , 4 5, 6 and Figure 7As shown, to address the problems in the prior art, the present invention provides a coating tool assembly suitable for different hole-reaming shapes, including a device body 1. An adjustment assembly 5 is mounted on the outer wall of the device body 1. The interior of the adjustment assembly 5 includes a fixing ring 51, first electric push rods 52, a sliding ring 53, a connecting frame 54, a rotating shaft 55, and a second motor 56. The fixing ring 51 is fixedly mounted on the outer wall of the device body 1. The bases of multiple sets of first electric push rods 52 are fixedly connected to the lower end of the fixing ring 51. The sliding ring 53 is slidably connected to the outer wall of the connecting cylinder 2. The upper end of the sliding ring 53 is fixedly connected to the output shaft of multiple sets of first electric push rods 52. Multiple sets of connecting frames 54 are fixedly mounted on the outer wall of the sliding ring 53. The rotating shaft 55 is rotatably connected inside the connecting frame 54. The output shaft of the second motor 56 is fixedly connected to one end of the rotating shaft 55. The second motor 56 is fixedly mounted on the connecting cylinder 2. On one side of the frame 54, one end of the mounting box 61 is fixedly connected to the outer wall of the rotating shaft 55. The reaming blade 62 is slidably connected inside the mounting box 61. The second motor 56 drives the rotating shaft 55 to rotate at a maximum angle of 180 degrees in the forward direction and 30 degrees in the reverse direction. The reaming tool assembly 6 is fixedly installed on the outer wall of the rotating shaft 55. The interior of the reaming tool assembly 6 includes the mounting box 61, the reaming blade 62, the slide groove 63, the fixing frame 64, and the second electric push rod 65. The mounting box 61 has two sets of slide grooves 63 inside. A set of fixing frames 64 is slidably connected in the slide grooves 63. A set of reaming blades 62 is placed inside the fixing frame 64. The reaming blades 62 and the fixing frame 64 are fixedly connected by bolts. The lower end of the fixing frame 64 is fixedly connected to the output shaft of the second electric push rod 65. The second electric push rod 65 is fixedly installed inside the mounting box 61.

[0027] In this invention, when it is necessary to enlarge a hole, the hole diameter is first expanded to accommodate the entire enlarging tool assembly 6. Then, the first electric push rod 52 is activated, which drives the sliding ring 53 to slide downward on the connecting cylinder 2. When the first electric push rod 52 extends to its maximum position, the enlarging tool assembly 6 will be located on the periphery of the tool 3. If a tapered hole needs to be processed at this time, the second motor 56 needs to be activated to reverse, which drives the rotating shaft 55 to rotate in the opposite direction. The rotating shaft 55 will drive the entire enlarging tool assembly 6 to rotate together, thereby changing the cutting angle of the enlarging tool assembly 6 to adapt to the processing of tapered holes. The operator can adapt to the size requirements of the tapered hole by changing the angle of rotation of the rotating shaft 55 driven by the second motor 56.

[0028] If a tapered hole needs to be machined, simply start the second motor 56 to rotate in the forward direction. This will drive the rotating shaft 55 to rotate in the forward direction, and the rotating shaft 55 will drive the reaming tool assembly 6 to rotate together, thereby changing the cutting angle of the reaming tool assembly 6 and thus achieving the machining of the tapered hole. There is no need for the operator to manually adjust the angle of the reaming tool assembly 6. When a normal cylindrical hole needs to be expanded and the hole diameter needs to be expanded significantly, simply control the extension of the second electric push rod 65. This will control the fixing frame 64 to slide inside the slide groove 63, thereby driving the reaming blade 62 to extend outward. The length of the extension of the reaming blade 62 can be controlled to adapt to the reaming requirements.

[0029] like Figure 2 as well as Figure 3 As shown, a chip removal assembly 4 is fixedly installed inside the main body 1 of the equipment. The chip removal assembly 4 includes a barrier cover 41, a drill bit 42, a suction box 43, an installation pipe 44, a connecting pipe 45, a vacuum cleaner 46, an exhaust pipe 47, a storage cylinder 48, and a first motor 49. The barrier cover 41 is fixedly installed at the lower end of the cutter 3, and multiple slots are formed on the outer wall of the barrier cover 41. The first motor 49 is fixedly installed at the top of the inside of the connecting cylinder 2. The output shaft of the first motor 49 is fixedly connected to the upper end of the storage cylinder 48. A set of vacuum cleaners 46 is fixedly connected to the lower end of the storage cylinder 48. The vacuum cleaners 46 are rotatably connected to the bottom plate inside the connecting cylinder 2. A set of air outlet pipes 47 are fixedly connected to both sides of the vacuum cleaner 46. There is a gap between the air outlet pipes 47 and the connecting cylinder 2. When the air outlet pipes 47 rotate, the air outlet at the upper end of the air outlet pipes 47 coincides with the air outlet at the upper end of the connecting cylinder 2. The first motor 49 drives the storage cylinder 48 to rotate at a positive angle of 35 degrees. The lower end of the vacuum cleaner 46 is fixedly connected to one end of the connecting pipe 45. The other end of the connecting pipe 45 is fixedly connected to one end of the mounting pipe 44. The connecting pipe 45 is rotatably connected to the inside of the cutter 3. Multiple sets of suction boxes 43 are fixedly connected to the outer wall of the mounting pipe 44. The suction boxes 43 are fixedly installed inside the drill bit 42. The drill bit 42 and the mounting pipe 44 are fixedly connected.

[0030] In this invention, after the first motor 49 is started to rotate, the first motor 49 will drive the storage cylinder 48 to rotate 30 degrees. The vacuum cleaner 46 and the drill bit 42 will also rotate 30 degrees under the drive of the storage cylinder 48. At this time, the inlet of the suction box 43 is aligned with the slot opened on the barrier cover 41. Then, the vacuum cleaner 46 is started, and it will suck the debris generated by the hole enlargement through the suction box 43 and the connecting pipe 45 into the storage cylinder 48 for storage. This makes it convenient for the staff to clean it later. It can also prevent the debris from being left in the hole when processing tapered or inverted tapered holes, which will aggravate the wear of the hole enlargement blade 62. This effectively improves the service life and working efficiency of the hole enlargement blade 62.

[0031] Working Principle: First, the main body 1 of the equipment is fixed on the drilling machine. Starting the machine rotates the main body 1 to perform drilling. When enlarging the hole, the diameter is first expanded to accommodate the entire enlarging tool assembly 6. Then, the first electric push rod 52 is activated, causing the sliding ring 53 to slide downwards on the connecting cylinder 2. When the first electric push rod 52 reaches its maximum position, the enlarging tool assembly 6 will be located outside the tool 3. If a tapered hole is to be machined, the second motor 56 is activated in reverse, causing the rotating shaft 55 to rotate in the opposite direction. The rotating shaft 55 then rotates the entire enlarging tool assembly 6, changing the cutting angle of the enlarging tool assembly 6 to accommodate the tapered hole. The operator can adjust the size of the tapered hole by changing the angle of rotation of the rotating shaft 55 driven by the second motor 56. If an inverted tapered hole is to be machined, the second motor 56 is activated in the forward direction. The principle of rotating the part is the same as the reverse rotation, only the direction of rotation is different, thus achieving the machining of the inverted tapered hole without requiring manual adjustment of the enlarging tool assembly. The 6-angle adjustment improves work efficiency. When a normal cylindrical hole needs to be expanded, and the hole diameter needs to be expanded significantly, simply control the extension of the second electric push rod 65. This will control the fixing bracket 64 to slide inside the slide groove 63, thereby driving the expanding blade 62 to extend outward. By controlling the extension length of the expanding blade 62, the expansion requirements can be adapted. While expanding the hole, the first motor 49 can be started to rotate. The first motor 49 will drive the storage cylinder 48 to rotate 30 degrees, while the vacuum cleaner 46, connecting pipe 45, mounting pipe 44, and suction box 43... The drill bit 42 will also rotate 30 degrees under the drive of the storage cylinder 48. At this time, the inlet of the suction box 43 is aligned with the notch opened on the barrier cover 41. After the adjustment is completed, the vacuum cleaner 46 is started. It will suck the debris generated by the hole enlargement through the suction box 43 into the storage cylinder 48 for storage via the installation pipe 44 and the connecting pipe 45. This makes it convenient for the staff to clean it later and can prevent the debris from being left inside the hole when processing tapered or inverted tapered holes, which would aggravate the wear of the hole enlargement blade 62 and reduce its working efficiency.
