Description

Technical Field

[0001] This utility model relates to a boring and milling cutter, specifically an easy-to-install boring and milling cutter, and belongs to the field of boring and milling cutter technology. Background Technology

[0002] A boring bar is a type of boring tool, usually with a round shank, although square shanks are sometimes used for larger workpieces. It is most commonly used for internal hole machining, reaming, and contouring. It has one or two cutting parts and is a tool specifically designed for roughing, semi-finishing, or finishing existing holes. Boring bars can be used on boring machines, lathes, or milling machines.

[0003] However, most existing boring and milling cutters have various problems. For example, in the boring and milling cutter disclosed in publication number CN205289769U, although it can be used with ordinary gantry milling machines to complete the machining of the width of large engine blocks, and has a simple structure and high machining efficiency, solving the problems of time-consuming, labor-intensive, and costly machining of engine block widths when using machining centers, the current boring and milling cutters are mainly composed of inserts and tool holders. During milling, the inserts need to be replaced according to the actual situation and the degree of damage. Currently, most of them use screws to lock the inserts and tool holders. When disassembling and assembling the inserts with screws, all screws need to be screwed into or out of the screw holes. Moreover, one insert often needs to be locked with multiple screws. During disassembly and assembly, each screw needs to be tightened, which is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] This utility model addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the purpose of this utility model is to overcome the aforementioned shortcomings in existing technologies by proposing an easy-to-install boring and milling cutter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An easy-to-install boring and milling cutter includes a tool holder, a fixed base, a boring insert, a stop plate, and a locking mechanism. The fixed base is fixed to the top of the tool holder, the boring insert is disposed on one side of the fixed base, and the stop plate is disposed on the side of the boring insert away from the fixed base. The boring insert and the stop plate are connected and locked to the fixed base by the locking mechanism.

[0007] The locking mechanism includes a connector, a threaded rod, a limiting plate, a nut, and a linkage unit. The threaded rod is coaxially fixed to one end of the connector and has a mating hole on the fixed base. The boring bar and the abutment plate both have through holes. The connector and the threaded rod pass through the through holes, and the connector mates with the mating hole on the fixed base. The mating head has a groove, and the limiting plate is engaged in the groove. A corresponding slot is provided in the mating hole on the fixed base, and the limiting plate is partially engaged in the slot. The nut is threadedly engaged with the threaded rod and abuts against the abutment plate.

[0008] As a further embodiment of this utility model: the linkage unit includes a positioning cylinder, a pressing rod, a linkage seat, a driving rod, and a driven rod. The positioning cylinder is coaxially fixed inside the threaded rod. The pressing rod is slidably connected to the threaded rod and the positioning cylinder, and the pressing rod passes through the positioning cylinder. The linkage seat is coaxially fixed to one end of the pressing rod and slidably connected to the internal cavity of the connector. The driving rod is rotatably connected between the limiting plate and the positioning cylinder, and the driven rod is rotatably connected between the limiting plate and the linkage seat.

[0009] As a further improvement of this utility model, the overall structure consisting of the linkage seat and the driven rod is provided with at least two sets.

[0010] As a further improvement of this utility model: a reset spring is provided at the bottom of the linkage seat, one end of the reset spring abuts against the linkage seat, and the other end abuts against one side of the cavity of the connector.

[0011] As a further improvement of this utility model: a round rod is fixed at the bottom center of the linkage seat, and the reset spring is sleeved on the outside of the round rod.

[0012] As a further improvement of this utility model: the top of the fixed base is provided with a spray hole, and a flow guiding cavity is provided inside both the knife bar and the fixed base, and the spray hole communicates with the flow guiding cavity.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, a locking mechanism is provided to allow the boring bar to mate with the fixed base. Simultaneously, the linkage unit within the locking mechanism allows the boring bar to move via a pressing rod during installation and locking. This, in turn, moves the driving rod and driven rod together, causing the limiting plate to move to the inside of the connector. At this point, the connector and threaded rod pass through the through holes of the boring bar and the abutment plate, aligning the connector with the mating hole on the fixed base. Releasing the pressing rod causes the linkage to reset under the force of the return spring, simultaneously moving the limiting plate. The limiting plate then engages with the slots in the mating holes of the connector and the fixed base. Tightening the nut completes the quick locking of the boring bar. During disassembly, pushing the pressing rod allows for quick separation of the connector and the fixed base. This quick-release connection structure allows for rapid assembly and disassembly of the boring bar, avoiding the need to fully screw in or out the screws. The operation is simple, time-saving, and labor-saving. Attached Figure Description

[0020] 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. Example 1

[0021] like Figures 1 to 4As shown, an easy-to-install boring and milling cutter includes a tool holder 1, a fixed base 2, a boring insert 3, a stop plate 4, and a locking mechanism 5. The fixed base 2 is fixed to the top of the tool holder 1, the boring insert 3 is disposed on one side of the fixed base 2, and the stop plate 4 is disposed on the side of the boring insert 3 away from the fixed base 2. The boring insert 3 and the stop plate 4 are connected and locked to the fixed base 2 by the locking mechanism 5.

[0022] The locking mechanism 5 includes a connector 51, a threaded rod 52, a limiting plate 53, a nut 54, and a linkage unit. The threaded rod 52 is coaxially fixed to one end of the connector 51 and has a mating hole on the fixed base 2. The boring bar 3 and the abutment plate 4 both have through holes. The connector 51 and the threaded rod 52 pass through the through holes, and the connector 51 mates with the mating hole on the fixed base 2. The connector 51 has a slot, and the limiting plate 53 is engaged in the slot. The mating hole on the fixed base 2 has a slot corresponding to the limiting plate 53, and the limiting plate 53 is partially engaged in the slot. The nut 54 is threadedly engaged with the threaded rod 52 and abuts against the abutment plate 4.

[0023] The linkage unit includes a positioning cylinder 55, a pressing rod 56, a linkage seat 57, a driving rod 58, and a driven rod 59. The positioning cylinder 55 is coaxially fixed inside the threaded rod 52. The pressing rod 56 is slidably connected to the threaded rod 52 and the positioning cylinder 55, and the pressing rod 56 passes through the positioning cylinder 55. The linkage seat 57 is coaxially fixed to one end of the pressing rod 56 and slidably connected in the internal cavity of the connector 51. The driving rod 58 is rotatably connected between the limiting plate 53 and the positioning cylinder 55, and the driven rod 59 is rotatably connected between the limiting plate 53 and the linkage seat 57.

[0024] A return spring 510 is provided at the bottom of the linkage seat 57. One end of the return spring 510 abuts against the linkage seat 57, and the other end abuts against one side of the cavity of the connector 51.

[0025] In this invention, a locking mechanism 5 is provided to enable the boring bar 3 to mate with the fixed base 2. Simultaneously, through the linkage unit within the locking mechanism 5, when the boring bar 3 is locked in place, the pressing rod 56 moves the linkage base 57, thereby linking the driving rod 58 and the driven rod 59. This causes the limiting plate 53 to move to the inside of the mating joint 51. At this point, the mating joint 51 and the threaded rod 52 pass through the through holes of the boring bar 3 and the abutment plate 4, and the mating joint 51 mates with the mating hole on the fixed base 2. Then, the pressing rod 5 is released. 6. The linkage seat 57 is reset under the elastic force of the reset spring 510, and simultaneously drives the limit plate 53 to move, so that the limit plate 53 is engaged between the slot in the mating hole on the connector 51 and the fixed seat 2. Then, the boring tool 3 can be quickly locked by tightening the nut 54. When disassembling, the connector 51 and the fixed seat 2 can be quickly separated by pushing the pressing rod 56. The quick disassembly and assembly connection structure allows the boring tool 3 to be quickly disassembled and assembled, avoiding the need to screw all the screws in or out. The operation is simple and saves time and effort. Example 2

[0026] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0027] The overall structure consisting of the linkage seat 57 and the driven rod 59 has at least two sets. The two sets of driven rods 59 limit the position of the limiting plate 53 to prevent the limiting plate 53 from tilting when moving.

[0028] A round rod is fixed at the bottom center of the linkage seat 57, and the return spring 510 is sleeved on the outside of the round rod, and the return spring 510 is limited by the round rod.

[0029] The top of the fixed base 2 is provided with a spray hole 6, and a flow guiding cavity is provided inside both the tool bar 1 and the fixed base 2. The spray hole 6 is connected to the flow guiding cavity, so that the external coolant can flow inside the tool bar 1 and the fixed base 2 through the flow guiding cavity, and be sprayed onto the surface of the boring tool 3 through the spray hole 6 to achieve a rapid cooling effect on the boring tool 3.

[0030] Working principle: When using this boring and milling cutter, first attach the boring insert 3 to one side of the fixed base 2, then attach the abutment plate 4 to one side of the boring insert 3. Then push the pressing rod 56 to move the linkage seat 57, which in turn drives the limiting plate 53 to move to the inside of the mating joint 51 through the driving rod 58 and the driven rod 59. At this time, the mating joint 51 and the threaded rod 52 pass through the through holes of the boring insert 3 and the abutment plate 4, and the mating joint 51 aligns with the mating hole on the fixed base 2. Then release the pressing rod 56, and the linkage seat... 57 is reset under the elastic force of the return spring 510, and simultaneously drives the limit plate 53 to move, so that the limit plate 53 is engaged between the slot in the mating hole on the connector 51 and the fixed seat 2. Then, the boring tool 3 can be quickly locked by turning the nut 54. When disassembling, first turn the nut 54 to loosen the threaded rod 52, and then push the pressing rod 56 to move the connector 51 to the inside of the connector 51, so that the connector 51 and the fixed seat 2 can be quickly separated.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
