Description

Technical Field

[0001] The utility model relates to the field of tooling, in particular to a clamping and fixing tooling used for processing sleeve parts in a horizontal machining center. Background Art

[0002] Wind power generation has developed rapidly in recent years due to its advantages such as no pollution and low construction cost. The processing efficiency and quality of the internal parts of the gearbox play a vital role. The gear transmission inside the gearbox is mainly divided into parallel-stage gear transmission and planetary-stage gear transmission. Among them, some gearbox models will contain sleeve parts in the parallel-stage gear transmission structure. According to the requirements of the gearbox designer, the outer circle of the sleeve parts sometimes has keyway processing requirements. When processing the keyway on the outer circle of the sleeve parts, they are usually placed flat on the machine tool workbench. Since the outer circle sizes of the sleeve parts used in different models of gearboxes are different, various types of tooling need to be made to meet the processing of sleeves of different specifications and models.

[0003] The technical solution of the prior art 1 is:

[0004] Place the sleeve parts on the vertical machining center for processing. Place the sleeve parts on the V-shaped irons on both sides, and then use the pressure plates to press the shaft diameter outer circles on both sides of the sleeve parts and then process the keyway on the shaft diameter outer circle.

[0005] The disadvantages of prior art 1 are:

[0006] 1. The tooling used for processing sleeve parts on the vertical machining center has a complex clamping method, a high production cost, and poor versatility.

[0007] 2. Sleeve parts with too large a difference in shaft diameter cannot use the same equal height blocks, and need to switch tooling, resulting in reduced processing efficiency.

[0008] 3. If the keyway and end surface of sleeve parts have angle requirements, the angle of the workpiece needs to be adjusted, and the clamping efficiency is low;

[0009] 4. Fixing by pressing the outer circles on both sides of the sleeve parts. If the pressing force on both sides of the sleeve parts is inconsistent, it is easy to cause the clamping method to be unstable and affect the quality of part processing.

[0010] The technical solution of the prior art 2 is:

[0011] Place the sleeve parts on the horizontal machining center for processing. First place the sleeve parts on two V-shaped irons, and then select the appropriate height of the spacer block according to the outer circle of the sleeve parts. Use it with the pressure plate. First place the bolt head of the tooling T-bolt into the T-slot of the machine tool, and the other side passes through the center hole in the middle of the pressure plate. Press the pressure plate onto the outer circle of the sleeve parts by tightening the nut.

[0012] The disadvantages of the second prior art are:

[0013] 1. The height of the spacer block is fixed. When encountering sleeve parts with different diameters, spacers of different heights are required, resulting in a waste of tooling;

[0014] 2. One side of the pressure plate is placed on the height block, and the other side is placed on the outer circle of the sleeve-like parts. If the height of the height block is significantly different from the outer circle height of the sleeve-like parts to be processed, it will easily lead to uneven force, making clamping time-consuming and labor-intensive.

[0022] The clamping module includes: T-type tooling bolts, tooling cover plates, and round nuts;

[0024] Four equal-height blocks are evenly distributed around the circumference.

[0025] The two ends of the obliquely placed support are respectively welded to the tooling base and the tooling column.

[0026] The utility model is beneficial in that:

This tooling can process sleeve parts within a certain height range, has stronger versatility, and saves tooling costs.

[0028] 2) The pressure plate is round, and the tooling pressure plate contacts the upper end surface of the sleeve-type parts, so the force is more uniform and the clamping is more stable.

[0031] 5) Simple structure, easy to process and manufacture;

[0032] 6) More versatile and saves tooling costs;

[0033] 7) Single person can operate, reducing labor costs;

[0034] 8) Adjust the clamping height of the pressure plate at any time so that it can be clamped and fixed in the most appropriate position, which makes the fixation more secure and improves the processing stability. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0040] like Figure 1 , Figure 2 As shown:

[0041] The utility model uses four equal height blocks 2. The equal height blocks 2 are directly placed on the machine tool worktable 3. After the four equal height blocks 2 are evenly arranged on the machine tool worktable 3 in a circumferentially uniform manner, the sleeve workpiece 1 to be processed is then placed on the equal height blocks 2.

[0042] The clamping module of the utility model comprises: a tooling base 4, a tooling column 5, a support 6, a T-shaped tooling bolt 7, a round nut 8, and a tooling round head bolt 9. The clamping module is mainly placed around the sleeve workpiece 1 to clamp and fix the sleeve workpiece 1.

[0043] The tooling base 4 and the tooling column 5 are fixed by welding to form an L-shaped tooling. In order to ensure the stability of the tooling, the two ends of the obliquely placed support 6 are respectively welded to the tooling base 4 and the tooling column 5 to play a reinforcing role.

[0044] After the tooling base 4 is placed on the machine tool worktable 3, the T-head 71 of the T-shaped tooling bolt 7 is installed in the T-slot 31 on the machine tool worktable 3, and the threaded portion of the T-shaped tooling bolt 7 passes through the through hole 41 pre-processed on the tooling base 4, and the round nut 8 is screwed onto the T-shaped tooling bolt 7. By tightening the round nut 8, the round nut 8 is pressed against the tooling base 4, and the tooling base 4 and the machine tool worktable 3 are fixedly connected.

[0045] A transverse threaded hole 51 is pre-opened on the side of the tooling column 5 facing the sleeve workpiece 1, and the tooling round head bolt 9 is screwed into the threaded hole 51 pre-opened on the side of the tooling column 5. The tooling round head bolt 9 is turned to control the contact with the outer circle of the sleeve workpiece 1, and the tooling round head bolt 9 is continuously tightened to clamp the sleeve workpiece 1. In the utility model, a total of four clamping modules are used, and the four clamping modules are evenly distributed around the axis of the sleeve workpiece 1.

[0046] The clamping module of the utility model comprises: a T-shaped tooling bolt 10, a tooling cover plate 11, and a round nut 12. The clamping module mainly functions to clamp and fix the sleeve workpiece 1 from above the sleeve workpiece 1.

[0047] After the T-shaped head 101 of the T-shaped fixture bolt 10 is installed in the T-shaped slot 31 on the machine tool worktable 3, the T-shaped fixture bolt 10 is passed through the center hole 100 of the sleeve workpiece 1. The threaded portion of the T-shaped fixture bolt 10 passes through the through hole 111 pre-processed on the fixture cover plate 11, and then the fixture cover plate 11 is placed on the sleeve workpiece 1, and the round nut 12 is installed on the T-shaped fixture bolt 10. By tightening the round nut 12, the round nut 12 presses the fixture cover plate 11, thereby pressing the fixture cover plate 11 onto the sleeve workpiece 1. In this way, the sleeve workpiece 1 can be pressed and fixed on the machine tool worktable 3.

[0048] Existing sleeve parts are placed horizontally on the horizontal machining center for processing. First, the sleeve parts are placed on two V-shaped irons, and then the appropriate height of the spacer block is selected according to the outer circle of the sleeve parts. Used in conjunction with the pressure plate, the bolt head of the tooling T-bolt is first placed in the T-slot of the machine tool, and the other side passes through the center hole in the middle of the pressure plate. The pressure plate is pressed onto the outer circle of the sleeve parts by tightening the nut. In the utility model, the sleeve workpiece can be placed vertically on the workbench for processing, and the processing is performed after the upper end face of the sleeve is pressed by the tooling cover plate, so that the workpiece is subjected to more uniform force during the processing. In addition, the spacer block used in the utility model is universal, and there is no need to match the tooling due to the different outer diameters of workpieces of different models. It has stronger versatility and effectively saves the cost of tooling.
