Description

Technical Field

[0001] The present application relates to the field of in-mold tapping, and in particular to an in-mold bevel tapping machine capable of quickly fine-tuning the angle. Background Art

[0002] Current tapping devices, especially those for bevel tapping, generally lack angle adjustment functions. In practical applications, molded parts will inevitably have certain tolerances. When designing and manufacturing bevel tapping devices, although the tapping angle is set according to the ideal design parameters, the device itself also has certain tolerances. As a result, the accumulation of tolerances will further increase the error of the tapping angle during use. This error causes the tapping angle to deviate from the design angle, affecting the accuracy of the thread and, in turn, the overall quality of the product.

[0003] Currently, in order to correct this angle deviation, manual adjustment is usually relied on through a bracket. This adjustment method is not only complicated to operate, but also requires technicians to have certain experience and skills. The adjustment process is time-consuming and labor-intensive, making it difficult to achieve efficient adjustment and production in large-scale production.

[0004] Therefore, it is of great practical significance to develop a tapping device that can quickly adjust the angle. Utility Model Content

[0005] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide an in-mold bevel tapping machine that can quickly perform angle fine-tuning. The tapping machine can reduce the thread angle error caused by tolerance accumulation by quickly adjusting the tapping angle, thereby improving the accuracy and consistency of thread processing.

[0006] To achieve the above purpose, the present application discloses an in-mold bevel tapping machine capable of quickly fine-tuning the angle, the tapping machine comprising a driving part and a tapping part connected and matched with the driving part, wherein:

[0007] The tapping part comprises a fixed seat matched with the driving part, a movable seat installed on the fixed seat with adjustable angle, and a tapping chuck installed in the movable seat and used for mounting the tapping tap;

[0008] The fixed seat is provided with a connecting gear that cooperates with the driving part, and an output gear installed in the fixed seat and used to drive the tapping chuck to work; the connecting gear and the output gear are connected and transmitted via a connecting shaft with a universal joint, so that when the angle between the movable seat and the fixed seat changes, the deformation of the universal joint is used to maintain the mechanical connection state.

[0009] In some embodiments, the tapping portion is detachably connected to the driving portion.

[0010] In other embodiments, the tapping portion and the driving portion are integrally connected.

[0011] In some embodiments, the driving part is a driving motor with a gear shaft.

[0012] In other embodiments, the driving part includes a main body connected to the tapping part, a power module installed on the main body, and a transmission gear set located in the main body and connected to the power module; one gear in the transmission gear set is meshed with the connecting gear, so that the power module indirectly drives the connecting gear to rotate.

[0013] As a preference, further speaking, the power module is composed of a transmission cup rotatably mounted in the body and a transmission screw inserted into the transmission cup; the transmission cup is meshed with at least one gear in the transmission gear set.

[0014] As another preferred embodiment, further speaking, the power module is an electric motor.

[0015] In some embodiments, the fixed seat and the movable seat are matched with bolts and a driving part through two waist-shaped screw holes to achieve angle adjustment.

[0016] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0017] 1. High-precision angle adjustment: The tapping angle can be fine-tuned by using the waist-shaped screw holes and bolts between the movable seat and the fixed seat, so that the equipment can accurately adapt to the tapping angle requirements of different workpieces.

[0018] 2. Stable transmission connection: Using a connecting shaft with a universal joint, the mechanical connection between the connecting gear and the output gear can be kept stable even when the tapping angle changes, ensuring the smooth progress of the tapping process.

[0019] 3. Diversified driving modes: The tapping part and the driving part can be fixedly connected or detachably connected. At the same time, the driving part can adopt a motor with a gear shaft or a power module including a transmission gear set, providing flexible driving options to adapt to different usage scenarios.

[0020] The above-listed beneficial effects are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementations will be further disclosed in the examples or other description parts of this application. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figure 1-3 As shown, this embodiment provides an in-mold bevel tapping machine that can quickly fine-tune the angle, which is mainly used in processing scenarios that require precise control of the tapping angle. The core design of the tapping machine is that it can make angle corrections during installation and debugging, or correct the tapping angle after the tapping angle of the product is adjusted, without the need to readjust the power transmission mechanism, thereby greatly improving processing efficiency and operational flexibility.

[0030] In this embodiment, the tapping machine comprises a driving part 1 and a tapping part 2, wherein the tapping part 2 comprises a fixed seat 201, a movable seat 202, a tapping chuck 203, a connecting gear 204, an output gear 205 and a connecting shaft 207 with a universal joint 206.

[0031] In the above structure, the fixed seat 201 is the core of the tapping part 2, provides support for the movable seat 202, and realizes precise angle adjustment through two waist-shaped screw holes 208. Based on the above structure, the movable seat 202 and the fixed seat 201 can flexibly adjust the matching angle to meet the tapping requirements of different workpieces or to correct the machine during the tapping test.

[0032] In this embodiment, the tapping chuck 203 is detachably mounted in the movable seat 202. The tapping chuck 203 fixes the tapping tap and drives the tapping tap to move back and forth to achieve tapping and backing. To drive the tapping chuck 203, a gear is provided on the tapping chuck 203, and the gear meshes with the output gear 205. Since the tapping chuck 203 has an initial bevel angle in this embodiment, the gear and the output gear 205 are both bevel gears.

[0033] During operation, since the connecting gear 204 and the output gear 205 are connected for transmission via the connecting shaft 207 with the universal joint 206, after the movable seat 202 is adjusted in angle relative to the fixed seat 201, the universal joint 206 is used to adaptively compensate for the changed angle to maintain the continuity of power transmission.

[0034] In this embodiment, the driving unit 1 provides power. Under normal conditions, there are multiple technical options, which are suitable for different operating scenarios.

[0035] For example: the driving part 1 is a driving motor with a gear shaft, which is suitable for scenarios that require direct and efficient driving, such as heavy-duty processing tasks with high torque and high-speed operation.

[0036] For another example, in this embodiment, if Figure 1 As shown, the driving unit 1 is a combination of a power module 101 and a transmission gear set 102, which is suitable for scenarios requiring precise transmission ratio adjustment, especially when tapping on bevel surfaces, and precise control of different angles and speeds can be achieved by adjusting the transmission gear set 102.

[0037] More specifically, the driving part 1 includes a body 103 connected to the tapping part 2 , a power module 101 mounted on the body 103 , and a transmission gear set 102 located inside the body 103 and connected to the power module 101 .

[0038] First, the main body 103 is the basic structure of the driving part 1, responsible for installing and supporting other components, and connected to the fixing seat 201 in the tapping part 2 to ensure the stability of power transmission.

[0039] In the above structure, the power module 101 is installed on the body 103 and is the core power source of the driving unit 1. In practice, the composition of the power module is different according to the specific design scheme.

[0040] In one implementation, Figure 3 As shown in FIG, the power module 101 is composed of a transmission cup 1001 rotatably mounted in a body 103 and a transmission screw 1002 inserted into the transmission cup 1001. The transmission cup 1001 is fixed in the body 103 by a bearing or a similar rotation support structure, and can rotate freely under the action of external power.

[0041] The transmission screw 1002 is inserted into the transmission cup 1001 and is tightly matched with it through threads or other connection methods. When the external power (such as a machine tool) drives the transmission screw downward, the transmission cup 1001 rotates accordingly. In addition, the transmission cup 1001 meshes with at least one gear in the transmission gear set 102, transmits power to other gears in the gear set 102, and finally meshes with the connecting gear 204 to achieve power output.

[0042] As another possible option, not shown in the drawings, the power module 101 can be in the form of a motor. This design directly uses the motor as a driving source, and drives the transmission gear set 102 through the rotational movement of the motor. In this case, the output shaft of the motor can directly mesh with a gear in the transmission gear set 102, simplifying the power transmission chain and possibly improving the overall efficiency and response speed of the system.

[0043] These two design solutions have their own advantages. The power module using the transmission cup 1001 and the transmission screw 1002 can achieve fine transmission ratio adjustment through different thread designs and gear combinations, which is suitable for scenarios that require precise control of tapping speed and angle. The design using a motor as the power module 101 can flexibly output power to meet the needs of some special usage scenarios.

[0044] It should be understood that no matter which design is chosen, the core task of the drive unit 1 is to ensure that power can be stably and efficiently transmitted to the tapping unit 2 to support the normal operation of the equipment under various working conditions.

[0045] It should also be understood that the main body 103 and the fixing seat 201 can use an integrated connection structure or a split connection structure. When the split structure is used, the tapping part 2 or the driving part 1 can be replaced as a unit, which is more flexible in use.

[0046] In actual operation, the angle fine-tuning function of the device is particularly suitable for workpieces that need to be tapped on an inclined surface. When facing a workpiece with an inclined hole, the operator can adjust the angle of the movable seat 202 to accurately align the tapping chuck 203 with the inclined surface of the workpiece. The specific operating steps are as follows: first loosen the bolts on the fixed seat 201 or the movable seat 202, allowing the movable seat 202 to slide in the waist-shaped screw hole 208; then adjust the angle of the movable seat 202 manually or using tools according to the inclined surface angle of the workpiece to ensure that the tapping chuck 203 forms a precise alignment relationship with the inclined surface of the workpiece; once the desired angle is reached, re-tighten the bolts to fix the movable seat 202 in the new position to ensure the stability of the angle during the tapping process.

[0047] This angle adjustment mechanism makes the equipment particularly convenient during on-site adjustment, especially when the angle of the workpiece is complex or changes frequently, and the operator can quickly respond and adjust the equipment to adapt to different process requirements. For example, when the production line changes to workpieces of different specifications, the operator can quickly adapt to the tapping requirements of the new workpiece by adjusting the angle of the tapping machine without having to make major adjustments or changes to the equipment, which greatly improves the flexibility and efficiency of the production line.

[0048] At the same time, the design of the tapping machine also makes it easier to operate in multi-angle processing. For example, when tapping multiple inclined surfaces of a complex part, the operator does not need to frequently change or reposition the workpiece. He only needs to adjust the angle of the tapping machine to continuously complete the tapping tasks of different inclined surfaces. This not only simplifies the operation process, but also reduces the errors that may be caused by moving or repositioning the workpiece, thereby improving the accuracy and consistency of processing.

[0049] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
