An inner cooling wire cone with a spiral cooling liquid circulation channel

Abstract

This utility model discloses an internally cooled tap with a spiral coolant circulation channel, including a support base, a transverse groove, a feed frame, a tap, and a feed mechanism. The transverse groove is transversely arranged at the center of the support base. The advantages of this utility model are: In this utility model, the vertical groove in the feed mechanism is combined with the active wedge plate to form a vertical transmission structure. The feed frame is driven by the active wedge plate and a linkage pulley for transverse feed motion. This design separates the traditional coaxial tap holder, feed mechanism, and rotation mechanism modules into multi-directional distributions, avoiding longitudinal redundancy caused by the superposition of functional modules along a single axis. This structure significantly shortens the overall length of the device, making it particularly suitable for narrow machining environments. Furthermore, the reset unit, through the spring force of the reset spring, allows the active wedge plate to move in the opposite direction, enabling the driven wedge plate to drive the feed frame in a synchronous reverse linkage, resulting in a simple and efficient design.

Description

Technical Field

[0001] This utility model relates to a tap, specifically an internally cooled tap with a spiral coolant circulation channel, belonging to the field of tap technology. Background Technology

[0002] A tap is a tool for machining internal threads. According to its shape, it can be divided into spiral flute taps, angled taps, straight flute taps, and pipe thread taps. According to the environment in which it is used, it can be divided into hand taps and machine taps. According to its specifications, it can be divided into metric, US, and imperial taps. Taps are the most mainstream machining tool used by operators in the manufacturing industry when tapping threads.

[0003] However, most existing taps have various problems. For example, in the internal cooling tap disclosed in announcement number CN206122832U, although it has the advantages of novel design, simple structure, durability, low vibration and good cooling effect, in the traditional design, the tap generally needs to be combined with core components such as spindle box, power box and feed slide during operation. These components are currently mostly arranged longitudinally along a single axis. For example, the spindle box is fixed at the left end of the bed, the feed box is located on the side, and the tailstock and rotating mechanism need to be arranged along the bed guide rail. Although this superimposed layout simplifies the transmission chain design, it leads to a significant increase in the total length of the equipment. Moreover, the excessively long bed not only occupies floor space, but also restricts the flexible deployment of the equipment in small workshops or automated production lines. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings of existing technologies by proposing an internal cooling tap with a spiral coolant circulation channel.

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

[0006] An internal cooling tap with a spiral coolant circulation channel includes a support base, a transverse groove, a feed frame, a tap, and a feed mechanism. The transverse groove is transversely disposed at the center of the support base. The feed frame is slidably engaged in the transverse groove. The tap is connected to one end of the feed frame. The feed mechanism is disposed in the support base.

[0007] The feeding mechanism includes a vertical chute, an active wedge plate, a linkage pulley, and a reset unit. The vertical chute is vertically through the center of the support base, and the intersection of the vertical chute and the horizontal chute is interconnected. The active wedge plate is slidably engaged in the vertical chute and is located in the upper half of the vertical chute. The linkage pulley is rotatably connected in the feeding frame, and the inclined surface of the active wedge plate abuts against one side of the linkage pulley.

[0008] As a further embodiment of this utility model: the feeding mechanism further includes a support platform and a cylinder, the support platform is fixed on the top of the support base, the cylinder is fixed at the center of the support platform, and the telescopic part of the cylinder is connected to the active wedge plate.

[0009] As a further embodiment of this utility model: the reset unit includes a driven wedge plate, a guide rod, and a reset spring. The driven wedge plate is slidably engaged with the lower half of the vertical slide groove, and the inclined surface of the driven wedge plate abuts against the other side of the linkage pulley. The guide rod is fixed to the end of the driven wedge plate away from the linkage pulley and is slidably connected to the support seat. The reset spring is sleeved outside the guide rod, and one end of the reset spring abuts against the driven wedge plate, and the other end abuts against the support seat.

[0010] As a further improvement of this utility model: a guide tube is fixed on the side wall of the tap, and a spiral coolant circulation channel is provided inside the tap, with the guide tube communicating with the channel.

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

[0014] In this invention, a vertical transmission structure is formed by combining a vertical slide groove and an active wedge plate in the feed mechanism.

This design separates the traditional coaxial layout of the tap holder, feed mechanism, and rotation mechanism into multi-directional distribution, avoiding longitudinal redundancy caused by the superposition of functional modules along a single axis. This structure significantly shortens the overall length of the device, making it particularly suitable for narrow machining environments.

[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 4 As shown, an internal cooling tap with a spiral coolant circulation channel includes a support base 1, a transverse slide 2, a feed frame 3, a tap 4, and a feed mechanism 5. The transverse slide 2 is transversely disposed at the center of the support base 1. The feed frame 3 is slidably engaged in the transverse slide 2. The tap 4 is connected to one end of the feed frame 3. The feed mechanism 5 is disposed in the support base 1.

[0022] The feeding mechanism 5 includes a vertical slide 51, an active wedge plate 52, a linkage pulley 53, and a reset unit. The vertical slide 51 is vertically installed through the center of the support base 1, and the vertical slide 51 and the transverse slide 2 are interconnected at their intersection. The active wedge plate 52 is slidably engaged in the vertical slide 51 and is located in the upper half of the vertical slide 51. The linkage pulley 53 is rotatably connected in the feeding frame 3, and the inclined surface of the active wedge plate 52 abuts against one side of the linkage pulley 53.

[0023] The feeding mechanism 5 also includes a support platform 54 and a cylinder 55. The support platform 54 is fixed on the top of the support base 1, and the cylinder 55 is fixed at the center of the support platform 54. The telescopic part of the cylinder 55 is connected to the active wedge plate 52.

[0024] The reset unit includes a driven wedge plate 56, a guide rod 57, and a reset spring 58. The driven wedge plate 56 is slidably engaged with the lower half of the vertical slide groove 51, and the inclined surface of the driven wedge plate 56 abuts against the other side of the linkage pulley 53. The guide rod 57 is fixed on the driven wedge plate 56 at one end away from the linkage pulley 53 and is slidably connected to the support base 1. The reset spring 58 is sleeved on the outside of the guide rod 57, and one end of the reset spring 58 abuts against the driven wedge plate 56, and the other end abuts against the support base 1.

[0025] In this invention, the vertical transmission structure is formed by combining the vertical slide 51 and the active wedge plate 52 in the feed mechanism 5, and the feed frame 3 is driven by the active wedge plate 52 and the linkage pulley 53 to perform the lateral feed motion. This design separates the traditional coaxial layout of tap holder, feed mechanism, rotation mechanism and other modules into multi-directional distribution, avoiding the longitudinal redundancy caused by the superposition of each functional module along a single axis. This structure greatly shortens the overall length of the device, and is especially suitable for narrow processing environments. In addition, by setting a reset unit, the active wedge plate 52 can be moved in the opposite direction by the elastic force of the reset spring 58, and the feed frame 3 can be driven synchronously in the opposite direction by the driven wedge plate 56, which is simple and efficient. 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] A guide tube 6 is fixed on the side wall of the tap 4, and a spiral coolant circulation channel is provided inside the tap 4. The guide tube 6 is connected to the channel, and internal cooling is achieved through the spiral coolant circulation channel to avoid the tap 4 from getting too hot during processing.

[0028] The tap 4 is fixed to the tail end with a mating plate 7. Screws are provided at the four corners of the mating plate 7, and the tap 4 is detachably connected to the feed frame 3 through the screws. The screws allow the tap 4 to be quickly disassembled and assembled.

[0029] A limiting groove 8 is provided through the active wedge plate 52, and a positioning rod 9 is fixed in the vertical sliding groove 51. The positioning rod 9 is slidably engaged in the limiting groove 8, and the displacement of the active wedge plate 52 is limited by the positioning rod 9.

[0030] When using this tap, first connect and lock the appropriate tap 4 to one side of the feed frame 3 via the mating plate 7. Then connect the guide pipe 6 to the external guide pipe to allow the coolant to circulate inside the tap 4 for internal cooling. Then the machining operation can begin. During machining, the cylinder 55 drives the active wedge plate 52 to slide. The active wedge plate 52 drives the feed frame 3 to move laterally via the linkage pulley 53, so that the tap 4 abuts against the workpiece. After machining is completed, the cylinder 55 retracts. At this time, the return spring 58 pushes the driven wedge plate 56 to move, and the driven wedge plate 56 drives the feed frame 3 to move in the opposite direction, thereby resetting the tap 4.

[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. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
