Description

Technical Field

[0001] The present application relates to the field of tapping, and more particularly to a horizontal tapping device for quick-changing taps. Background Art

[0002] The rapid development of modern manufacturing industry has put forward higher efficiency and convenience requirements for mechanical processing equipment. Among many processing equipment, horizontal tapping machine is a key equipment widely used in metal processing, mold manufacturing and other fields. Its performance directly affects the efficiency of the entire production process. However, the traditional horizontal tapping machine design has certain limitations, especially in the installation and replacement of taps (tools for processing internal threads).

[0003] In the existing old horizontal tapping machine design, such as Figure 1 and 2 As shown in the figure, the tap chuck is usually fixed at the front end of the machine and integrated with the machine. This design will cause a series of operational inconveniences and efficiency problems when processing certain specific workpieces, especially when the space between the tap and the product to be processed is small. Since the tap cannot be removed forward alone, when the operator needs to replace the tap, he often has to move the entire machine backward to free up enough space for the removal and installation of the tap. This method is not only cumbersome to operate, but also particularly difficult and time-consuming when processing large machines, which seriously affects production efficiency.

[0004] In view of this problem, it is particularly necessary to develop new technologies to optimize and improve the structure of existing horizontal tapping machines. Utility Model Content

[0005] The present application aims to overcome at least one of the shortcomings of the prior art and to provide a horizontal tapping device that allows for quick removal of taps without moving or disassembling the entire machine.

[0006] To achieve the above objectives, the present application discloses a horizontal tapping device with quick-change taps, including a tapping machine body with a preset installation position and a tapping assembly. The tapping assembly is inserted from the rear along the tapping direction and is detachably fixed in the installation position.

[0007] To realize the basic drive of tapping, the tapping machine body has a driving mechanism, a transmission assembly connected to the driving mechanism, and a hollow gear shaft installed in the installation position and matched with the transmission assembly, and the driving mechanism rotates via the transmission assembly and the hollow gear shaft;

[0008] In order to realize quick change of taps, the tapping assembly can be detachably inserted and matched with the gear shaft, and tapping is realized through the hollow gear shaft; the tapping assembly includes a tailstock with a spring, a tap chuck inserted into the tailstock and matched with the spring, and a tap installed on the tap chuck; the tap chuck is inserted into the hollow gear shaft and moves synchronously with the hollow gear shaft; the tailstock can be detachably installed on the tapping machine body, and the spring in the tailstock makes the tap chuck have an elastic retreat position, so that the tap retreats for protection in case of abnormal processing or the tap cannot tap the product;

[0009] In order to realize the tapping action, a synchronous pitch thread matching the tap is arranged in the tap chuck, and the tap chuck drives the tap to move forward and backward while rotating, so as to realize tapping and thread removal.

[0010] In some embodiments, the driving mechanism is a combination of a screw and a transmission cup, and the transmission screw is driven by an external mechanism or component.

[0011] In other embodiments, the driving mechanism is a combination of a motor with controlled rotation and a controller.

[0012] In some embodiments, the transmission assembly is composed of a plurality of gears meshing with each other to achieve variable speed and torque transmission.

[0013] In some embodiments, the tailstock in the tapping assembly is detachably connected to the tapping machine body by a rotating slot and a fixing bolt.

[0014] In some embodiments, the hollow gear shaft is sleeved with a bevel gear meshing with the transmission assembly, and the corresponding transmission assembly has a bevel gear matching with the bevel gear.

[0015] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0016] 1. Improve operational efficiency and convenience: By achieving quick removal of the taps, there is no need to move or disassemble the entire machine, greatly simplifying the tap replacement process. This design significantly improves production efficiency, which is especially important for operating environments that require frequent tap changes.

[0017] 2. Reduce machine downtime: In traditional equipment, the tap replacement process is cumbersome and causes long machine downtime. The new design significantly reduces downtime through a quick tap replacement mechanism, thereby improving overall production efficiency.

[0018] 3. Simplified operation and improved safety: New technologies simplify the operation process, reduce the complexity of operation, and reduce the risk of operational errors, thereby improving operational safety.

[0019] 4. Strong adaptability: The new tapping device provides a variety of drive mechanisms and transmission components through different embodiments, which increases the adaptability of the equipment and can meet different production needs and working environments.

[0034] like Figure 3-6As shown, this embodiment discloses an exemplary structure of a technical solution for achieving the purpose of the present application. As shown in the figure, in this embodiment, it is composed of a tapping machine body 1 having a horizontal mounting position 3 that passes through in the tapping direction and a tapping assembly 2, wherein the tapping assembly 2 is inserted from the tail of the mounting position 5 away from the tapping work position and is detachably fixed in the mounting position 5 to meet the needs of tapping.

[0035] Specifically, in the present embodiment, the tapping machine body 1 is the main structure of the horizontal tapping device, and is usually made of strong and durable materials to ensure the stability and durability of the machine during long-term use.

[0036] In terms of design, the tapping machine body 1 has a certain space and structure to accommodate and install corresponding parts.

[0037] More specifically, as the structural basis for the quick-operation and disassembly of the tap 4, a special mounting position 5 is designed in the tapping machine body 1, and the mounting position 5 is a through slot, in which a hollow gear shaft 6 is mounted through a bearing, and the hollow gear shaft 6 can rotate freely, and a bevel gear 7 is provided on the outer sleeve of the hollow gear shaft 6, and the bevel gear 7 is used to connect and cooperate with a bevel gear in the transmission assembly 8, and is driven to rotate by the transmission assembly 8; as a necessary component of the tapping machine body 1, the driving mechanism 9 is also installed on the tapping machine body 1. In most embodiments, the driving mechanism 9 is a combination of a screw and a transmission cup. This structure is widely used and is very mature, so its specific structure, composition, and working principle are no longer described in detail.

[0038] In some other embodiments, the driving mechanism 9 is a combination of a motor and a controller that is controlled to rotate. This structure is mainly used to meet the use requirements of some complex or special workstations. Its corresponding structure is also used in this field and belongs to the prior art, so it will not be described in detail.

[0039] In the above structure, it should be understood that the transmission assembly 8 is connected to the driving mechanism 9 and is responsible for transmitting power from the driving mechanism to the tapping assembly 2. The transmission assembly 8 is composed of a plurality of mutually meshing gears in most cases, and in some cases, a transmission shaft is also included to meet the needs of long-distance transmission. However, in the above structure, in order to achieve the cooperation with the bevel gear 7 outside the hollow gear shaft 6, the final output of the transmission assembly 8 is a bevel gear (not shown in the figure).

[0040] As the final implementation component of tapping, in this embodiment, the tapping assembly 2 structurally includes a tailstock 11 with a built-in spring, a tap chuck 12 inserted into the tailstock 11 and matched with the spring, and a tap 4 installed on the tap chuck 12. First, the tap chuck 12 is adapted to the hollow channel in the hollow gear shaft 6 in terms of appearance and structure, so that the tap chuck 12 can rotate synchronously with the hollow gear shaft 6 after being inserted into the hollow gear shaft 6.

[0041] In the above structure, the tap 4 is mounted on the tap chuck 12 and is the tool part directly used for tapping. The tap 4 can be selected in different types and specifications according to different processing requirements.

[0042] In order to meet the needs of tapping and backing, a synchronous pitch thread matching the tap 4 is provided in the tap chuck 12, and the tap 4 is driven to move forward and backward while the tap chuck 12 rotates. It should be understood that the specific structure of the above design belongs to the prior art in this field, and the specific structure and method will not be described in detail.

[0043] In the above structure, the tailstock 11 is designed to be detachably mounted on the tapping machine body 1. This design is intended to facilitate the installation, disassembly and maintenance of the tapping assembly 2. The tailstock 11 fixes the tap chuck 12 in one direction and provides an elastic retreat position to prevent damage to the tap 4 or the device caused by misalignment of the tap 4.

[0044] When this embodiment is implemented, by plugging and pulling out the tapping assembly 2 as a whole from the rear, the tap 4 can be replaced conveniently and quickly, with high speed and efficiency, which can better meet the needs of modern industrial production.

[0045] 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.
