Description

TECHNICAL FIELD

[0001] The application relates to the technical field of mechanical devices, in particular to a large-size elastic clamp mounting structure for a single-point diamond lathe. BACKGROUND

[0002] In traditional ultra-precision machining, a workpiece is machined by directly vacuum-sucking an elastic clamp to a main shaft of a machine tool and then clamping the workpiece by the elastic clamp. Although the elastic clamp is installed by this method, the installation is relatively convenient and fast, but when machining a large-size workpiece, the elastic clamp itself usually has a relatively large outer diameter and a relatively heavy weight, and requires a relatively high vacuum suction force. In addition, the elastic clamp rotates at a high speed on the main shaft, and has a very large inertia. During the machining process, the elastic clamp may fall off the main shaft at any time, and the workpiece will also be damaged and may injure the operator after falling off, which has a great safety hazard. CONTENT OF THE UTILITY MODEL

[0003] To solve or partially solve the problems in the related art, the application provides a large-size elastic clamp mounting structure for a single-point diamond lathe, which increases a transition piece between a main shaft and a clamp to stably install the elastic clamp.

[0004] The first aspect of the application provides a large-size elastic clamp mounting structure for a single-point diamond lathe, which comprises an elastic clamp, a transition piece, a fixing bolt and a main shaft. The transition piece is arranged corresponding to the main shaft, and a plurality of counterbores are uniformly distributed on the outer edge corresponding to the bolt hole of the main shaft. The fixing bolt penetrates the counterbores and the bolt hole of the main shaft to connect the transition piece and the main shaft. The transition piece is provided with mounting holes corresponding to the bolt holes of the elastic clamp. The elastic clamp is connected to the transition piece based on the fixing bolt. The mounting holes are arranged in multiple rows to connect elastic clamps of different specifications.

[0005] The outer diameter of the transition piece is consistent with the diameter of the main shaft, the axial positioning end face is provided, and the cylindricity is less than 0.005 mm.

[0006] The flatness of the end face of the transition piece is less than 0.01 mm.

[0007] The technical scheme provided by the application can have the following beneficial effects:

[0008] The application provides a large-size elastic clamp mounting structure for a single-point diamond lathe, which safely and stably installs a large-size elastic clamp on a main shaft of a machine tool by a transition piece, and then clamps a workpiece by the elastic clamp for machining. The structure does not rely on a vacuum suction force, avoids the risk of the elastic clamp falling off the main shaft, reduces the risk of the workpiece falling off and being damaged during the machining process, and ensures the personal safety of the operator.

[0020] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 The mounting structure of a large-size elastic clamp 1 for a single-point diamond lathe shown includes: elastic clamp 1, transition piece 2, fixing bolt 3, and spindle 4.

[0022] Transition piece 2 is integrally formed and annealed, corresponding to spindle 4. Made of LY12 steel, the annealing process ensures the overall rigidity and hardness of transition piece 2 while preventing residual machining stress from affecting installation accuracy. The outer diameter of transition piece 2 matches that of spindle 4. Its axial positioning end face has a cylindricity of less than 0.005mm, ensuring concentricity after connection with spindle 4 and elastic clamp 1. Its thickness is 25mm, ensuring no deformation due to bolt compression during installation, thus preventing uneven contact with spindle 4 and elastic clamp 1, and avoiding wasted travel in the Z-axis direction of the machine tool. The end face flatness is less than 0.01mm, ensuring consistency and uniformity in fastening with spindle 4 and elastic clamp 1. Figure 2 As shown, the outer edge of the spindle contact end face 4-2 of the transition piece 2 has 6 connecting holes 2-1 evenly distributed with the 6 bolt holes of the spindle 4. The fixing bolt 3 passes through the connecting holes 2-1 and the bolt holes of the spindle 4 to connect the transition piece 2 with the spindle 4.

[0023] like Figure 3As shown, the elastic clamp contact end face 2-3 of the transition piece 2 is provided with mounting holes 2-2 corresponding to the bolt holes of the elastic clamp 1, and the elastic clamp 1 is connected with the transition piece 2 based on the fixing bolt 3. Since the elastic clamp 1 has different sizes, six rows of bolt holes for installing the elastic clamp 1 are reserved in the transition piece 2 at intervals of 10 mm, so that the elastic clamp 1 of different sizes can be installed. The mounting holes 2-2 and the bolt holes on the elastic clamp 1 are all designed as evenly distributed counterbores, which ensures the installation of the transition piece 2 and the elastic clamp 1, avoids affecting the dynamic balance of the main shaft 4 due to uneven arrangement and bolt leakage when the main shaft 4 rotates at high speed, and also takes into account the aesthetics after installation.

[0024] When installing the elastic clamp 1, the transition piece 2 is first fixed on the rotating main shaft 4 through the fixing bolt 3, the concentricity of the transition piece 2 and the main shaft 4 is corrected by using a lever micrometer to align the outer diameter 2-5 of the transition piece 2, and after correction, the six evenly distributed hexagonal bolts on the edge of the transition piece 2 are tightened. Then the elastic clamp 1 is fixed on the transition piece 2 through the three evenly distributed bolts at the bottom, the concentricity of the clamp and the main shaft 4 is corrected by using a lever micrometer to align a regular surface on the edge of the elastic clamp 1, and after correction, the three hexagonal bolts at the bottom of the clamp are tightened, so that the large-size elastic clamp 1 is safely and stably installed on the machine tool main shaft 4. After installation and fixation, the main shaft 4 drives the transition piece 2 and the clamp to rotate, and the clamp outer circle runout is less than 0.005 mm before it can be used. Then the workpiece is clamped by the elastic clamp 1 for machining.

[0025] Finally, it should be noted that in this document, relationships such as first and second, and the like, are merely used to distinguish one entity or action from another, and do not necessarily require or imply any actual relationship or order between or among such entities or actions.
