Description

Technical Field

[0001] This utility model relates to the field of deep hole drilling technology, specifically a horizontal four-axis deep hole drilling multi-workpiece feeding fixture. Background Technology

[0002] Deep hole drilling is widely used in modern manufacturing industries such as aerospace, automotive, military, and precision machinery, especially when machining complex parts and multiple workpieces, where the requirements for machining accuracy and efficiency are particularly stringent. To improve machining efficiency and reduce production costs, designing an efficient, precise, and flexible workpiece feeding system has become an important research direction in deep hole drilling technology.

[0003] In the existing technology, two main workpiece feeding schemes are used: split single-axis feeding mechanism and multi-station independent feeding system, but both of these schemes have certain defects and limitations.

[0004] Split-type single-axis feeding mechanism: This system uses a stepper motor to drive a ball screw, which in turn pushes a nut seat to achieve sequential feeding of single workpieces. While this method has certain advantages in simple single-workpiece machining, it has the following drawbacks:

[0005] The clamping components of this feeding mechanism are typically fixed V-grooves, which are only suitable for regular bar shapes and not for workpieces of various shapes or sizes. When faced with workpieces of diverse shapes, the feeding system exhibits poor flexibility and adaptability.

[0006] This method can only complete the feeding of a single workpiece at a time, resulting in a long work cycle and failing to fully utilize the processing capacity of the drilling machine, thus limiting the improvement of production efficiency.

[0007] Multi-station independent feeding system: This system uses multiple sets of independent lead screws to drive the slides of each axis, enabling multiple workpieces to be fed simultaneously. However, due to the lack of effective coordination planning of the motion trajectories of each axis, interference often occurs in the motion paths of the workpieces during feeding. Especially in the processing of multiple workpieces, without precise control, interference between stations can lead to equipment damage or poor workpiece machining, affecting production efficiency and processing quality.

[0008] The design of multiple independent axis slides may cause spatial interference between the feeding of each station. Especially in the processing of complex parts or in the case of high precision requirements, spatial interference may affect the accuracy and smoothness of feeding, and may even lead to equipment failure or misoperation.

[0009] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a horizontal four-axis deep hole drilling multi-workpiece feeding fixture. Utility Model Content

[0010] The purpose of this invention is to provide a horizontal four-axis deep hole drilling multi-workpiece feeding fixture to solve the problems mentioned in the background art.

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] A technical solution for a horizontal four-axis deep hole drilling multi-workpiece feeding fixture includes: a base;

[0013] A servo module mounted on a base, the servo module comprising a servo motor and a feeder driven by the servo motor;

[0014] The lifting mechanism is provided on both sides of the base. The lifting mechanism includes a lifting cylinder, a lifting seat connected to the lifting cylinder, and multiple sets of V-shaped brackets fixed on the lifting seat.

[0015] The guide rails are symmetrically distributed below the lifting seat, and the limiting slide is slidably installed on the guide rails, the limiting slide being connected to the base.

[0016] As a preferred technical solution, the servo module drives the ball screw through a servo motor, which in turn drives the feeder to move synchronously along a linear trajectory.

[0017] As a preferred technical solution, the V-shaped bracket can be detachably installed on the lifting seat, and the V-shaped bracket can be adapted to bar workpieces of different diameters.

[0018] As a preferred technical solution, the lifting mechanism is arranged in pairs symmetrically on the feeding rack, and each station is equipped with at least one set of lifting cylinders.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model is a horizontal four-axis deep hole drilling multi-workpiece feeding fixture. The servo module is set up to precisely control the movement of the feeding frame through the servo motor, which improves the accuracy and stability of feeding, ensures the positional accuracy of the workpiece during the processing, and thus improves the processing quality.

[0021] The detachable design of multiple V-shaped brackets allows the tooling to be flexibly adapted to workpieces of different shapes and sizes, enhancing the tooling's versatility and adaptability, and reducing the adjustment time and cost required when changing workpieces.

[0022] The paired symmetrically arranged lifting mechanisms, combined with the design of the limiting slide, effectively avoid interference problems in the multi-station feeding process, ensuring smooth and safe feeding, while improving processing efficiency.

[0028] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for a horizontal four-axis deep hole drilling multi-workpiece feeding fixture: it includes a base 1, which is the basic component of the entire feeding fixture. Its design needs to have sufficient strength and stability to support the entire fixture system. The base 1 is typically made of high-strength steel or cast iron, and its surface flatness and the accuracy of the mounting holes are ensured through precision machining. The bottom of the base 1 has mounting holes for fixing it to the worktable of the deep hole drilling machine.

[0030] The servo module 2 includes a servo motor 21 and a feeder 22 driven by the servo motor 21. The servo motor 21 is connected to the feeder 22 via a ball screw to achieve precise linear motion control. The servo module 2 is mounted on the base 1, and its position and angle are adjusted according to actual processing requirements to ensure that the feeder 22 can accurately feed the workpiece into the processing area of ​​the deep hole drilling machine.

[0031] The lifting mechanism 3 includes a lifting cylinder 31, a lifting seat 32, and multiple sets of V-shaped brackets 33. The lifting cylinder 31 is controlled by a pneumatic system to achieve rapid lifting and lowering. The lifting seat 32 is fixed to both sides of the base 1, and the lifting cylinder 31 is connected to the lifting seat 32. The extension and retraction of the cylinder pushes the lifting seat 32 up and down. The V-shaped brackets 33 are fixed to the lifting seat 32 and are used to support the workpiece. The V-shaped brackets 33 are designed to be detachable so that they can be replaced according to the shape and size of the workpiece, improving the versatility of the tooling.

[0032] Guide rails 41 are symmetrically distributed below the lifting seat 32, and limiting slides 42, which are slidably mounted on the guide rails 41, are connected to the base 1. The function of the limiting slides 42 is to limit the movement range of the lifting seat 32, ensuring the stability and safety of the workpiece during the lifting process. At the same time, the limiting slides 42 also serve as guides, ensuring the smooth movement of the lifting seat 32.

[0033] In the actual processing, the workpiece to be processed is first placed on the V-shaped bracket 33. The servo module 2 is started, and the servo motor 21 drives the feeder 22 to move along a linear trajectory, sending the workpiece into the processing area of ​​the deep hole drilling machine. During the processing, the lifting mechanism 3 realizes the lifting and lowering of the workpiece through the extension and retraction of the lifting cylinder 31, and in conjunction with the movement of the servo module 2, completes the continuous feeding of multiple workpieces.

[0034] The entire feeding fixture system should be equipped with necessary safety protection devices, such as emergency stop buttons and limit switches, to ensure operational safety. At the same time, key components such as the servo module 2 and the lifting mechanism 3 should be inspected and maintained regularly to ensure the stability and reliability of the feeding fixture.

[0035] Through the above specific implementation methods, the horizontal four-axis deep hole drilling multi-workpiece feeding fixture of this utility model can effectively solve the problems existing in the prior art, improve the efficiency and accuracy of deep hole drilling, and has good application prospects.
