Description

Technical Field

[0001] This utility model relates to the field of machining, specifically to an improved vertical machine tooling. Background Technology

[0002] In the machining industry, machining the outer cylindrical surface of a workpiece is a common and crucial process. Traditional machining processes typically use a chuck to hold the workpiece in place, but this method has certain limitations. On the one hand, chuck clamping is insufficient to meet the requirement of machining the outer cylindrical surface of a workpiece in one continuous operation, resulting in low machining efficiency. On the other hand, uneven distribution of chuck clamping force can easily lead to insecure workpiece mounting, causing displacement during machining, which in turn affects machining accuracy. It can also cause vibration, resulting in a decrease in workpiece surface quality and an increased scrap rate.

[0003] Furthermore, when clamping workpieces of varying thicknesses, existing clamping structures lack effective adjustment mechanisms. When dealing with thinner workpieces, the clamping rod assembly has a fixed length, requiring multiple rotations of the clamping nut during plate removal, which consumes a significant amount of time and severely impacts processing efficiency. Conversely, when dealing with thicker workpieces, the rod may be too short to achieve effective clamping. This lack of versatility and inconvenient adjustment makes existing processing equipment ill-suited to diverse production needs, becoming a bottleneck restricting the efficient development of the machining industry.

[0004] Therefore, those skilled in the art have provided improved vertical bed fixtures to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide an improved vertical bed fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An improved vertical machine tooling includes a positioning support plate, on which a workpiece to be processed is placed. Multiple clamping rod assemblies passing through the workpiece are evenly distributed along the circumference of the positioning support plate. A pressure plate is provided on the workpiece to be processed around the clamping rod assembly. A clamping nut is threadedly connected to the clamping rod assembly above the pressure plate.

[0008] The positioning support plate has a positioning mounting slot at its center, and a central positioning plate is placed inside the positioning mounting slot. A positioning protrusion is integrally formed on the outer edge of the central positioning plate to provide mounting positioning for the workpiece to be processed.

[0009] As a further embodiment of this utility model: three jaw clearance grooves are evenly distributed along the circumference of the positioning support plate to avoid the jaws clamping on the three-jaw chuck, and the positioning support plate is mounted on a vertical lathe via the three-jaw chuck.

[0010] As a further improvement of this utility model: multiple pads are fixed at equal intervals on the upper periphery of the positioning support plate. The pads are made of hard plastic, which can prevent scratches on the parts.

[0011] As a further embodiment of this utility model: the clamping rod assembly includes a stud, a threaded hole at the bottom of the stud, a second stud threaded inside the threaded hole, and a locking nut located at the bottom of the stud and surrounding the second stud.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When processing workpieces, this utility model can satisfy the one-time processing of the outer cylindrical surface of the workpiece to be processed. Moreover, by replacing the chuck with clamping, it can effectively ensure that the installation of the workpiece to be processed is more secure. Axial clamping can effectively prevent the occurrence of vibration.

[0014] 2. This utility model allows for the adjustment of the position of stud two within the threaded hole by rotating the stud two inside the threaded hole. Then, the locking nut is used to lock stud one and stud two together, thereby adjusting the height of the clamping rod assembly. This solves the problem of time-consuming disassembly of the clamping nut when disassembling the pressure plate due to the excessive length of the clamping rod assembly when clamping workpieces of different thicknesses.

[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 1-4 In this embodiment of the utility model, the improved vertical machine tooling includes a positioning support plate 1, a workpiece 9 to be processed is placed on the positioning support plate 1, and a plurality of clamping rod assemblies 2 passing through the workpiece 9 are evenly distributed on the positioning support plate 1 along the circumferential direction. A pressure plate 3 located on the workpiece 9 is provided around the clamping rod assembly 2, and a clamping nut 4 is threadedly connected to the clamping rod assembly 2 above the pressure plate 3.

[0022] The positioning support plate 1 has a positioning mounting slot 102 in the center, and a central positioning plate 5 is placed inside the positioning mounting slot 102. A positioning protrusion 6 is integrally formed on the outer edge of the central positioning plate 5 to provide mounting positioning for the workpiece 9 to be processed.

[0023] By adopting the above technical solution, this tooling is clamped on the worktable of the vertical lathe 7, and the positioning is achieved by the positioning protrusion 6 on the central positioning plate 5. Then, the workpiece 9 to be processed can be pressed by tightening the clamping nut 4 and the pressure plate 3. This can satisfy the one-time processing of the outer circle surface of the workpiece 9. Moreover, by pressing instead of chuck support, the installation of the workpiece 9 to be processed can be effectively ensured to be more secure. Axial pressing can effectively avoid the occurrence of vibration.

[0024] The positioning support plate 1 has three jaw clearance grooves 101 evenly distributed along its circumference to avoid the jaws 801 clamping jaws on the three-jaw chuck 8. The positioning support plate 1 is mounted on the vertical lathe 7 via the three-jaw chuck 8.

[0025] Among them, multiple pads 10 are fixed at equal intervals on the outer periphery of the positioning support plate 1. The pads 10 are made of hard plastic, which can prevent scratches on the parts.

[0026] The clamping rod assembly 2 includes a stud 201, a threaded hole 202 at the bottom of the stud 201, a second stud 203 threaded inside the threaded hole 202, and a locking nut 204 located at the bottom of the stud 201 and surrounding the second stud 203.

[0027] After adopting the above technical solution, the position of stud 203 in the threaded hole 202 can be adjusted by rotating stud 203 inside the threaded hole 202. Then, the locking connection between stud 1 201 and stud 203 can be achieved by locking nut 204, thereby realizing the height adjustment of clamping rod assembly 2. This solves the problem that when clamping workpieces 9 of different thicknesses, the clamping rod assembly 2 is too long, which makes it time-consuming to disassemble clamping nut 4 when disassembling pressure plate 3.

[0028] The working principle of this utility model is as follows: In use, the positioning support plate 1 is clamped by the three-jaw chuck 8 of the vertical lathe 7, and then the central positioning plate 5 is installed. The workpiece 9 to be processed can be placed on the positioning support plate 1 and positioned by the positioning protrusion 6 on the central positioning plate 5. Then, by rotating the clamping nut 4, the workpiece 9 to be processed can be clamped by the pressure plate 3. The upper end face and outer cylindrical face of the workpiece 9 to be processed can be machined by the vertical lathe 7, which can meet the one-time processing of the outer cylindrical face of the workpiece 9 to be processed. Moreover, by clamping instead of chuck support, the installation of the workpiece 9 to be processed can be effectively ensured to be more secure. Axial clamping can effectively prevent the occurrence of vibration.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
