Description

Technical Field

[0001] This utility model belongs to the field of linear optical axis machining technology, specifically relating to a tooling fixture for machining hollow linear optical axes. Background Technology

[0002] A linear optical shaft is a precision-machined cylindrical rigid shaft whose core function is to provide low-friction, high-precision linear motion guidance. Its performance depends on the materials, heat treatment processes, and geometric accuracy, and it is widely used in industrial automation, precision machinery, and other fields. A linear optical shaft is a high-precision cylindrical mechanical transmission element primarily used to support and guide linear motion components, enabling them to move smoothly and with low friction along a fixed trajectory. It is one of the core components of a linear motion system and is typically used in conjunction with linear bearings, sliders, or bushings. A hollow linear optical shaft is a mechanical transmission element, usually made of metallic materials (such as steel, aluminum alloy, or stainless steel), and has a hollow cylindrical structure; it is often used in conjunction with linear bearings.

[0003] Hollow linear optical shafts are generally produced by boring the optical shaft body. However, in the current boring process, only the external part of the optical shaft body is clamped by a fixture, lacking clamping force along the axis of the optical shaft body. This can easily lead to uneven force during the boring process, causing the optical shaft body to tilt, which to some extent affects the yield of the finished product. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling fixture for machining hollow linear optical shafts, so as to solve the problem that in the prior art, only the external part of the optical shaft body is clamped by a fixture during the boring process, which easily leads to the optical shaft body being skewed during the boring process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A tooling fixture for machining a hollow linear optical axis is used to bore the optical axis body. It includes an external clamping assembly, which consists of a mounting bracket, two sets of side supports, and two clamping blocks. The opposing end faces of the two clamping blocks are both configured as clamping concave surfaces. An end fixing assembly is detachably mounted on the external clamping assembly. When bore machining the optical axis body, a groove is first formed at one end. Then, the end with the groove on the optical axis body is fixed by the cooperation of the external clamping assembly and the end fixing assembly. Finally, bore machining is performed from the other end of the optical axis body until it penetrates the groove, completing the machining process.

[0006] Preferably, the end fixing assembly includes a mounting disc, an end fixing post is fixedly inserted in the middle of the mounting disc, the end of the end fixing post is matched with the boring groove, and two quick couplings are symmetrically installed on the outside of the mounting disc to realize the quick assembly of the end fixing assembly and the outer clamping assembly.

[0007] Preferably, the quick-connect component includes a ring fixedly connected to the outer edge of the mounting disc, a connecting stud fixedly inserted in the middle of the ring, and a locking nut with threaded engagement installed on the end of the connecting stud opposite to the ring.

[0008] Preferably, the clamping block has a through hole in the middle for inserting and installing the connecting stud, and two stop pins are symmetrically installed on the connecting stud.

[0009] Preferably, the connecting stud has two symmetrically formed grooves on its outer side, and the two grooves are respectively set to correspond to two stop protrusions.

[0010] Preferably, each of the rings has two reinforcing ribs symmetrically arranged on its outer edge about the axis of the connecting stud, and both reinforcing ribs are fixedly connected to the outer edge of the mounting disc.

[0011] Preferably, the length of the end insertion post is less than the opening depth of the boring groove.

[0012] Preferably, two handles are symmetrically installed on the side of the mounting disc about the axis of the end insertion post, and both handles are designed in a U-shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Based on the external clamping assembly, this utility model adds an additional positioning effect on the optical axis body along its axial direction, thereby ensuring the stability and reliability of the optical axis body during the boring process, reducing the probability of the optical axis body becoming skewed, and ensuring the yield of finished products.

[0014] 2. When processing non-hollow linear optical axes, this utility model can be used by simply removing the end fixing component attached to the outer clamping assembly, making the operation flexible and free, and applicable to a wide range of applications. Attached Figure Description

[0017] 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.

[0018] Reference Figures 1-4 As shown, this utility model provides a tooling fixture for machining a hollow linear optical axis, used for bore machining of the optical axis body 1. It includes an outer clamping assembly 2, which is composed of a mounting bracket 21, two sets of side supports 22, and two clamping blocks 23. The opposite end faces of the two clamping blocks 23 are both set as clamping concave surfaces 231. An end fixing assembly 3 is detachably installed on the outer clamping assembly 2. When bore machining the optical axis body 1, a boring groove 11 is first formed at one end. Then, the end of the optical axis body 1 with the boring groove 11 is fixed by the cooperation of the outer clamping assembly 2 and the end fixing assembly 3. Then, the bore is formed from the other end of the optical axis body 1 to the boring groove 11 to complete the machining.

[0019] The end fixing assembly 3 includes a mounting disc 31, with an end fixing post 32 fixedly inserted in the center of the mounting disc 31. The length of the end fixing post 32 is less than the opening depth of the boring groove 11. In this way, the end with the boring groove 11 on the optical axis body 1 is fixed by the cooperation of the outer clamping assembly 2 and the end fixing assembly 3. Then, the boring is passed through the bore at the other end of the optical axis body 1 to the boring groove 11. In this process, even in the final stage, the presence of the end fixing post 32 will not affect the boring operation, and there will be no interference or resistance between the end fixing post 32 and the operation. The design is practical and flexible. The end of the fixing post 32 is matched with the boring groove 11. Two quick-connect parts 34 are symmetrically installed on the outside of the mounting disc 31 to achieve quick assembly of the end fixing component 3 and the outer clamping component 2. The quick-connect part 34 includes a ring 342 fixedly connected to the outer edge of the mounting disc 31. A connecting stud 343 is fixedly inserted in the middle of the ring 342. A locking nut 344 with its thread is installed on the end of the connecting stud 343 facing away from the ring 342. The end fixing component 3 can be freely, flexibly and quickly assembled and disassembled on the outer clamping component 2. Based on the outer clamping component 2, an additional positioning effect is added to the optical axis body 1 along its axis, thereby ensuring the stability and reliability of the optical axis body 1 during the boring process, reducing the probability of the optical axis body 1 becoming skewed, and ensuring the yield of finished products.

[0020] In a further embodiment, refer to Figure 4 As shown, the clamping block 23 has a through hole 232 in the middle for the connecting stud 343 to be inserted and installed, and two stop pins 345 are symmetrically installed on the connecting stud 343.

[0021] In this embodiment, the stop pin 345 can ensure the stability of the end fixing component 3 after it is assembled on the outer clamping component 2 by abutting the two sides of the clamping block 23 after the locking nut 344 is locked, thereby reducing the occurrence of shaking and other situations, and improving the clamping and positioning effect of the device on the optical axis body 1.

[0022] In a further embodiment, refer to Figure 4 As shown, each ring 342 has two reinforcing ribs 341 symmetrically arranged on its outer edge about the axis of the connecting stud 343, and both reinforcing ribs 341 are fixedly connected to the outer edge of the mounting disc 31.

[0023] In this embodiment, the reinforcing rib 341 can improve the connection strength between the ring 342 and the mounting disc 31, and ensure the stability of the end of the two clamping blocks 23 after the connecting stud 343 and the clamping block 23 are locked. This enables the positioning of the optical axis body 1 outside and at a specific end along the axis, greatly improving the reliability during the processing.

[0024] In a further embodiment, refer to Figure 3As shown, two handles 33 are symmetrically mounted on the side of the mounting disc 31 about the axis of the end insertion post 32, and both handles 33 are designed in a U-shape.

[0025] In this embodiment, it is convenient to lift the end fixing component 3 as a whole, and it is also convenient to disassemble and install the end fixing component 3 as a whole.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
