Description

Technical Field

[0001] This utility model specifically relates to a positioning fixture for processing round tube products. Background Technology

[0002] When pipes undergo grinding, laser cutting, welding, and sawing, tooling is needed to position the product and ensure dimensional requirements such as size and flatness. However, tooling design is usually based on the contour of the product, such as... Figure 3 As shown, the upper and lower mold cavities are made. When positioning the product, the product and the cavity are in surface contact. The machining of the cavity requires high precision. Moreover, the cavity cannot be properly vented during placement, which affects the placement of the product. After the product is placed into the tooling cavity, there is a situation where it appears to fit visually, but the actual positioning is inaccurate, resulting in poor product dimensions or scrap. This type of tooling design has defects. Therefore, we propose a positioning tooling for the machining of round tube products. Utility Model Content

[0003] The purpose of this utility model is to provide a positioning fixture for processing round tube products, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for processing round tube products, comprising:

[0005] A base plate, on which a positioning block is fixed;

[0008] Preferably, the bump assembly includes a first bump and a third bump. The first bump is fixed to one end of the upper surface of the positioning block, and a second bump is provided at the other end of the upper surface of the positioning block. The first bump and the second bump are located on the same side of the positioning cavity. The third bump is provided in the middle of the upper surface of the positioning block and corresponds to the other side of the positioning cavity.

[0009] Preferably, the first protrusion is provided in two locations, and the two locations of the first protrusion are symmetrically distributed along one end of the positioning cavity.

[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.

[0021] Please see Figures 1-3 This utility model provides a technical solution: a positioning fixture for processing round tube products, comprising:

[0022] Base plate 1, with positioning block 2 fixed on base plate 1;

[0023] The positioning cavity 3 is formed on the positioning block 2 to position the edge of the circular tube, and the cross-section of the positioning cavity 3 is non-circular;

[0024] To facilitate the positioning of the round tube product, the contact area between the inner wall of the positioning cavity 3 and the round tube is reduced, thereby facilitating the tight fit and positioning of the product with the bottom inner side of the positioning cavity 3 when placing the round tube product. The cross-section of the positioning cavity 3 is preferably rectangular.

[0025] The bump assembly protrudes from the upper surface of the positioning block 2, and the bump assembly is distributed along the long side of the positioning cavity 3;

[0026] The raised section facilitates the placement of the round tube product, allowing it to move downwards with its own weight to achieve a complete fit with the bottom of the inner side of the positioning cavity 3.

[0027] In this embodiment, preferably, the bump assembly includes a first bump 4 and a third bump 6. The first bump 4 is fixed to one end of the upper surface of the positioning block 2, and a second bump 5 is provided at the other end of the upper surface of the positioning block 2. The first bump 4 and the second bump 5 are located on the same side of the positioning cavity 3. The third bump 6 is provided in the middle of the upper surface of the positioning block 2, and the third bump 6 corresponds to the other side of the positioning cavity 3.

[0028] This facilitates positioning of the two opposite sides of the round tube product, allowing the round tube product to be accurately placed inside the positioning cavity 3, thus avoiding any tilting of the round tube product during placement.

[0029] In this embodiment, preferably, the first protrusion 4 is provided in two places, and the two first protrusions 4 are symmetrically distributed along one end of the positioning cavity 3;

[0030] This facilitates more precise positioning of the end of the round tube product, so that the round tube product can automatically move down under the action of gravity to fit tightly against the bottom of the inner side of the positioning cavity 3.

[0031] In this embodiment, preferably, the first protrusion 4, the second protrusion 5 and the third protrusion 6 are all integrally formed with the positioning block 2.

[0032] In this embodiment, preferably, a mating groove is provided at the bottom of the inner side of the positioning cavity 3, and a baffle 8 for positioning one end of the round tube is connected to the mating groove;

[0033] This facilitates positioning one end of the round tube product, thereby adjusting the length of the other end of the round tube product extending out of the positioning cavity 3.

[0034] In this embodiment, preferably, a limiting cover plate 7 is rotatably installed on the upper surface edge of the positioning block 2, and a handle is rotatably connected to one end of the limiting cover plate 7. A standing block 9 is fixed on the bottom plate 1, and a slot 10 for limiting the handle is opened on one side wall of the standing block 9.

[0035] This facilitates locking the round tube product between the positioning cavity 3 and the limiting cover plate 7, so as to prevent the round tube product from moving randomly and affecting the processing accuracy.

[0036] In this embodiment, preferably, the long side of the positioning block 2 is smaller than the long side of the base plate 1, and the positioning block 2 is fixed to the base plate 1 by bolts;

[0037] It is easy to install and fix, and facilitates maintenance and replacement in the future.

[0038] This invention changes the cross-section of the positioning cavity 3 to a rectangle and adds a protruding component, avoiding the problem of the traditional positioning cavity 3 having the same cross-section as the circular tube. The circular tube and the inner wall of the positioning cavity 3 are in surface contact, requiring high precision in the machining of the positioning cavity 3. Furthermore, it is difficult to expel the gas inside the positioning cavity 3 when placing the tube inside, affecting the accurate positioning effect. This device has a simple structure, provides line contact when positioning the tube, has relatively low machining precision requirements, and allows for good air expulsion from the inside of the positioning cavity 3 when placing the tube. During placement, the tube's own weight ensures a good fit with the bottom of the positioning cavity 3, guaranteeing excellent positioning and ease of use.

[0039] 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.
