Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of machining, in particular to a machining fixture for a convex plate. Background Art
[0002] In the manufacturing industry, a convex plate is generally a plate-shaped part with an arc surface, and is often used as a key load-bearing and connecting component for supports such as bridges and light rails. Through the designed arc surface structure, the requirements for multi-directional mechanical transmission and displacement adjustment are met.
[0003] In the current machining method, milling is a relatively flexible machining method, which can machine various shapes such as planes (including horizontal planes, vertical planes, curved surfaces, inclined planes, etc.), grooves, and steps; while turning is mainly used for machining rotary parts (such as geometric shapes like cylinders, cones, or spheres), and turning is relatively difficult to process planes or complex shapes. Therefore, at present, the milling method is generally used for machining the arc surface of plate-shaped parts.
[0004] However, although milling has high precision and flexibility, it requires the use of high-precision and high-quality equipment, resulting in high production costs. And due to the design structure of the milling machine, it needs to be fixed on the working plane during machining and can only be accurately formed through multiple feeds and adjustments of the tool path, resulting in a long machining process for a single part. At the same time, in the face of the current environment of large-scale production requirements, the low efficiency and high cost problems of milling are more prominent. This makes the current processing of convex plates have low production efficiency and high costs.
[0005] Therefore, to solve the problems of low processing efficiency and high costs for existing convex plates, a machining fixture for a convex plate is now needed. Summary of the Utility Model
[0006] The purpose of the utility model is to provide a machining fixture for a convex plate, which has a simple structure and is easy to operate, and can be directly applied to the turning machining method for mass production, effectively reducing production costs while improving production efficiency.
[0007] To achieve the above object, the utility model adopts the following technical solutions:
[0008] The utility model can directly apply the convex plate to turning processing, which has lower cost compared with milling processing, and can be applied to the production of convex plates of various specifications, with higher versatility. It realizes mass production, improves production efficiency, and at the same time improves the consistency of product quality. Specifically, it provides a machining fixture for a convex plate, including a main shaft for matching installation with a lathe, and a support plate assembly for positioning at least one convex plate sleeved on the main shaft; an end plate assembly for limiting the corresponding convex plate is arranged outside the support plate assembly; a positioning plate for fixing with the lathe is arranged at one end of the main shaft; the positioning plate is arranged outside the end plate assembly; wherein, the support plate assembly is of a polygonal structure, and at most one convex plate can be positioned on each side; a plurality of mounting ears are arranged around the end plate assembly, the mounting ears are arranged in a circular arrangement and respectively correspond to the positions of the sides of the support plate assembly, and the end of the convex plate is fixed on the corresponding mounting ear.
[0009] The principle and advantages of this solution are as follows:
[0010] In this solution, by setting a support plate assembly of a polygonal structure and an end plate assembly including a corresponding number of mounting ears, the convex plates can be respectively mounted at the side lengths of the support plate assembly, so that a cylindrical structure is formed between the multiple convex plates, thereby converting the processing of a plane into the processing of a rotating body part, and then it can be used for turning processing to replace the milling processing method. Compared with milling processing, its processing efficiency is higher and the production cost is lower. At the same time, by selecting the polygonal structure of the support plate assembly and the number of mounting ears, the processing quantity of the convex plate 2 can be flexibly set, realizing effective mass production, improving production efficiency and ensuring the consistency and product stability of the convex plate processing.
[0011] Furthermore, the support plate assembly includes a first support plate and a second support plate, the first support plate and the second support plate have the same structure and are respectively arranged at both ends of the main shaft; a middle connecting pipe is arranged between the first support plate and the second support plate; the middle connecting pipe is sleeved on the periphery of the main shaft.
[0012] Furthermore, the end plate assembly includes a first end plate and a second end plate; the first end plate is arranged on one side of the first support plate and is connected with the positioning plate; a first connecting pipe is arranged between the first end plate and the first support plate, and the first connecting pipe is sleeved on the periphery of the main shaft.
[0013] Furthermore, the second end plate has the same structure as the first end plate, the second end plate is arranged on the other side of the second support plate and is sleeved on the main shaft.
[0014] Furthermore, fixing holes are correspondingly arranged on each side of the first support plate and the second support plate, and the convex plate is fixed on each side of the support plate assembly through the fixing holes.
[0015] Furthermore, positioning holes are provided on each mounting ear of the first end plate and the second end plate. The two ends of the corresponding convex plate respectively correspond to the positioning holes of the first end plate and the second end plate, and are limited between the first end plate and the second end plate by positioning pins.

[0026] The following is a further detailed description through specific embodiments:
[0027] The figure marks in the drawings of the specification include: main shaft 1, convex plate 2, positioning plate 3, through hole 4, first support plate 5, second support plate 6, middle connecting tube 7, mounting ear 8, first end plate 9, second end plate 10, first connecting tube 11, positioning hole 12, arc surface 13, fixing hole 14.
[0028] The embodiment is basically as shown in the attached Figure 1 As shown: A convex plate machining device includes a spindle 1 for matching and installing with a lathe. The spindle 1 can be driven to rotate by the lathe, thereby driving the tooling to rotate. A support plate assembly for positioning at least one convex plate 2 is detachably mounted on the spindle 1. An end plate assembly for limiting the corresponding convex plate 2 is detachably mounted on the outer side of the support plate assembly. A positioning plate 3 for fixing with the other end of the lathe is installed at the front end of the spindle 1 by bolts, and the positioning plate 3 is installed on the outer side of the end plate assembly. In this embodiment, the positioning plate 3 is set to a square shape according to the structure of the lathe to facilitate installation and fixation, avoid relative sliding, and ensure the stability of the tooling during processing. The entire tooling can be clamped and fixed on the lathe workbench by the spindle 1 and the positioning plate 3, and the tooling can be rotated around the spindle 1 to facilitate turning processing.
[0029] As attached Figure 2 As shown, the cross section of the support plate assembly is a polygonal structure, and at most one convex plate 2 can be positioned on each side, that is, the convex plate 2 is fixed to the side of the support plate assembly by bolts. Figure 3 and Figure 4 As shown, the convex plate 2 is generally a plate-like member with a curved surface 13 on one side. During its production process, through holes 4 for installation are left at both ends. This solution makes full use of the through holes 4 of the convex plate 2 to position and install the convex plate 2 on the support plate assembly, which ensures the clamping stability without affecting the structure and performance of the convex plate 2.
[0030] In this embodiment, the support plate assembly is an equilateral polygon structure, and the arc of the central angle R corresponding to each side length is not less than the arc α of the corresponding convex plate arc surface 13. This facilitates the installation of the convex plate 2 without affecting the placement of adjacent convex plates 2. At the same time, a support plate assembly containing a corresponding number of side lengths can be selected according to convex plates 2 of different specifications to improve the versatility and applicability of the tooling.
[0031] As attached Figure 1 and attached Figure 2As shown, the support plate assembly includes a first support plate 5 and a second support plate 6. In this embodiment, the first support plate 5 and the second support plate 6 have the same structure and are respectively installed at both ends of the main shaft 1. The spacing distance between them is the distance between two through holes 4 on the convex plate 2 of the corresponding specification, so as to ensure the effective installation and positioning of the convex plate 2. A middle connecting pipe 7 is installed between the first support plate 5 and the second support plate 6 by bolts. The middle connecting pipe 7 is sleeved around the main shaft 1. In this embodiment, the middle connecting pipe 7 is of a cylindrical structure, and its diameter is smaller than the diameter of the circumcircle of the support plate assembly. It can not only protect the main shaft 1 and reduce the slag falling on the surface of the main shaft 1, but also fixedly support the support plate assembly, improve the stability of the support plate assembly, and will not affect the installation of the convex plate 2.
[0032] Fixing holes 14 are correspondingly formed on each side of the first support plate 5 and the second support plate 6. The through holes 4 on the convex plate 2 are respectively fixedly installed with the corresponding fixing holes 14 by bolts, so that the convex plate 2 is fixed on each side of the support plate assembly.
[0033] As shown in the attachment Figure 5 As shown, a plurality of mounting ears 8 are integrally formed around the end plate assembly. In this embodiment, the mounting ears 8 are arranged in a circular pattern and respectively correspond to the positions of each side of the support plate assembly, that is, each mounting ear is correspondingly arranged above the position where each side of the support plate assembly is located, so that a one-to-one correspondence relationship is formed between the mounting ears 8 and each side of the support plate assembly. In this embodiment, the diameter of the circumcircle of the end plate assembly is larger than the diameter of the circumcircle of the support plate assembly to ensure that the convex plate 2 can be clamped inside the end plate assembly. When installing the convex plate 2, first fix the convex plate 2 on the side of the support plate assembly, and place the two ends of the convex plate 2 on the corresponding mounting ears of the end plate assembly respectively. In this embodiment, according to the structural dimensions of the convex plate 2 to be processed, the support plate assembly with different numbers of polygon structures and the end plate assembly with the corresponding number of mounting ears can be correspondingly selected. Generally, the number can be selected from 4 to 10 to adapt to the processing of convex plates 2 of different sizes, improve the versatility, and ensure quick and accurate installation.
[0034] In this embodiment, as shown in the attachment Figure 1As shown in the figure, the end plate assembly includes a first end plate 9 and a second end plate 10. The structures of the first end plate 9 and the second end plate 10 are the same, and the distance between them is set according to the length of the convex plate 2 to be processed, generally not exceeding 2-4 mm of the overall length of the convex plate 2, so as to facilitate installation and fixation. Among them, the first end plate 10 is installed on one side of the first support plate 5 and is connected to the positioning plate 3 for easy disassembly and replacement. The second end plate 10 is installed on the other side of the second support plate 6, that is, from the direction shown in the figure, it is the lower end of the second support plate 6 and is sleeved on the main shaft 1. In this way, the convex plate 2 is fixed between the first end plate 9 and the second end plate 10 to ensure the stability of the convex plate 2 during processing. At the same time, a first connecting pipe 11 is also installed between the first end plate 9 and the first support plate 5 by bolts, and the first connecting pipe 11 is sleeved around the main shaft 1. In this embodiment, the first connecting pipe 11 is of a cylindrical structure, and its diameter is smaller than the diameter of the circumcircle of the support plate assembly. Specifically, the diameter of the first connecting pipe 11 is the same as the diameter of the middle connecting pipe 7, which can play a role in supporting and fixing while ensuring the safe operation of the main shaft 1 and reducing the influence of processing residues.
[0035] Positioning holes 12 are respectively opened on each mounting ear 8 of the first end plate 9 and the second end plate 10. The two ends of the corresponding convex plate 2 respectively correspond to the positioning holes 12 of the first end plate 9 and the second end plate 10, and are limited between the first end plate 9 and the second end plate 10 by positioning pins.
[0036] The specific implementation process is as follows:
[0037] As shown in the Figure 1 to Figure 6 figures, when the convex plate 2 needs to be processed, first select a support plate assembly with a corresponding number of sides and an end plate assembly with a corresponding number of mounting ears according to the size of the convex plate 2, such as a support plate assembly and an end plate assembly with 8 sides and 8 mounting ears.
[0038] During installation, first install the second end plate 10 on the main shaft 1 and make it located at the lower end position of the main shaft 1, so that the distance between the second end plate 10 and the top of the main shaft 1 is equivalent to the length of the convex plate 2 for easy and quick adjustment and fixation. Then install and connect the second support plate 6, the middle connecting pipe 7 and the first support plate 5 according to the distance between the two through holes 4 on the convex plate 2, so that the distance between the first support plate 5 and the second support plate 6 is equal to the distance between the two through holes 4, and at the same time ensure that the vertex positions of the side lengths of the first support plate 5 and the second support plate 6 are aligned. In this embodiment, the middle connecting pipe 7 can be replaced and selected according to the actual length to meet the distance setting requirements. Fix the assembled support plate assembly on the main shaft 1 by bolts and sleeve it, and it is located above the second end plate 10, so that the distance between the second support plate 6 and the second end plate 10 is the same as the distance between the lower through hole 4 of the convex plate 2 and the bottom end of the convex plate 2.
[0039] Install the first end plate 9 on the main shaft 1 according to the distance between the through hole 4 at the upper end of the convex plate 2 and the top of the convex plate 2, and locate it above the first support plate 5, so that the mounting ear positions of the first end plate 9 and the second end plate 10 correspond to each other and are aligned with the center of the position where the side length of the first support plate 5 is located. Finally, install the positioning plate 3 on the first end plate 9 and fix it on the main shaft 1.
[0040] According to the structure of the convex plate 2 to be processed and the maximum number that can be installed, fix the convex plate 2 on the first support plate 5 and the second support plate 6 by bolts respectively, that is, make the through hole at the upper end of the convex plate 2 correspond to the fixing hole 14 of the first support plate 5, and the through hole at the lower end of the convex plate 2 correspond to the fixing hole 14 of the second support plate 6. Finally, fix both ends of the convex plate 2 on the positioning holes 12 of the first end plate 9 and the second end plate 10 through positioning pins to complete the processing and clamping of multiple convex plates 2.
[0041] Install the clamped tooling on the corresponding lathe workbench through the main shaft 1 and the positioning plate 3, and then the turning operation can be realized to complete the machining of the arc surfaces of multiple workpieces.
[0042] In this embodiment, according to the structure of the convex plate 2, the support plate assembly and the end plate assembly are designed respectively, and multiple convex plates can be arranged and installed on the tooling in a circumferential form, converting the plane machining method into a rotary body machining method, so as to be applicable to turning processing operations, replace the milling processing method, realize the simultaneous machining of multiple workpieces at one time, improve the processing efficiency while reducing the production cost, and at the same time ensure the consistency and stability of the product processing quality.

It should be pointed out that for those skilled in the art, without departing from the technical solutions of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
