Description

Technical Field

[0001] The utility model belongs to the field of bearing processing, and in particular relates to a numerically controlled lathe for high-stability bearing processing. Background Art

[0002] CNC machine tools refer to machine tools controlled by CNC technology, which are used to process various parts and workpieces. In the field of bearing processing, CNC machine tools are usually used in the manufacturing and processing of bearings; the application of CNC machine tools in bearing processing can achieve high-precision, high-efficiency and automated processing. They can control the processing technology and motion trajectory through pre-programmed instructions, thereby realizing the processing of complex bearing shapes and sizes.

[0003] When CNC machine tools process bearings, the existing technology mostly uses a single-size bearing cage to position the bearing workpiece. However, a single-size bearing cage can only be used for bearings of a specific size and cannot adapt to bearings of different sizes. At the same time, the bearing is fixed only by the bearing cage, and its processing stability is insufficient. In actual processing, different bearings may have different outer diameters, inner diameters and widths, so cages of different sizes are required for positioning processing. Using a single-size cage will limit the flexibility and scope of application of processing. At the same time, using a single-size bearing cage may require the manufacture and maintenance of multiple sizes of cage stocks, which increases costs and management complexity. Therefore, a high-stability CNC lathe for bearing processing is proposed to solve the above problems. Utility Model Content

[0004] In response to one or more of the above defects or improvement needs of the prior art, the utility model provides a high-stability CNC lathe for bearing processing, which has the advantages of being able to position and clamp bearing workpieces of different sizes, thereby reducing processing costs and processing efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides a high-stability CNC lathe for bearing processing, comprising a CNC machine tool body;

[0006] The CNC machine tool body is provided with two sets of linear screw modules; the two sets of linear screw modules are slidably assembled with linear moving platforms, and the linear moving platforms are provided with positioning components;

[0007] The positioning assembly includes four positioning seats arranged on a linear moving platform. The four positioning seats are arranged in a rectangular shape. A light rod is arranged between two opposite positioning seats. Sliding shaft seats are slidably provided on the two light rods. A clamping block is assembled between two adjacent sliding shaft seats. The two clamping blocks are arranged opposite to each other and a placement seat is clamped between them.

[0008] As a further improvement of the utility model, clamping notches are provided on opposite sides of the two clamping blocks, and the two clamping notches are arranged opposite to each other and are provided in a triangular shape.

[0009] As a further improvement of the utility model, a carrying plate is detachably provided on the upper end surface of the placing seat by means of bolts, and an inner conical surface is provided on the carrying plate along the center of the circle.

[0010] As a further improvement of the present invention, a positioning column is vertically arranged at the center of the supporting plate, and the end of the positioning column is arranged in a hemispherical shape.

[0011] As a further improvement of the utility model, a plurality of rubber blocks are arranged around the center of the upper end surface of the carrier plate, each of the rubber blocks is arranged in an arc shape and is soft as a whole, and one end of each of the rubber blocks is rotatably arranged on the carrier plate through a rotating shaft.

[0012] As a further improvement of the utility model, two guide rod motors are further arranged on the linear moving platform, the output ends of the two guide rod motors are arranged opposite to each other and are both connected to motor push rods, and the two motor push rods are respectively extended to be connected to the side of one of the clamping blocks.

[0013] In general, compared with the prior art, the above technical solutions conceived by the utility model have the following beneficial effects:

[0014] The utility model discloses a high-stability CNC lathe for processing bearings. In actual use, through the mutual movement and coordination of multiple components in the positioning assembly, the user places the bearing workpiece to be processed on the carrier plate, and at the same time, by rotating the rubber block, several rubber blocks can surround the outside of the bearing workpiece. At the same time, the motor push rod pushes the clamping block radially, so that the two clamping blocks can drive the clamping notches to move in opposite directions until the two clamping notches clamp the outside of the rubber blocks. At this time, the two clamping notches clamp the rubber blocks, and the rubber blocks surround the outside of the bearing workpiece, and finally the outside of the bearing workpiece is clamped by the two clamping notches. Compared with the load-bearing installation of the traditional bearing retainer, the two clamping notches that move against each other can ensure that the bearing workpiece has higher stability during processing, and at the same time, the time for replacing the bearing retainer during bearing processing is reduced. The positioning assembly can adapt and clamp bearings of various models and sizes, and the overall practicality is stronger. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] Depend on Figure 1-4 Provided is a CNC lathe for high-stability bearing processing, comprising a CNC machine tool body 1;

[0023] Two sets of linear screw modules 2 are arranged on the CNC machine tool body 1; a linear moving platform 21 is slidably assembled on the two sets of linear screw modules 2, and a positioning component 3 is arranged on the linear moving platform 21;

[0024] The positioning assembly 3 includes four positioning seats 31 arranged on the linear moving platform 21. The four positioning seats 31 are arranged in a rectangular shape. A light rod 32 is arranged between two opposite positioning seats 31. A sliding shaft seat 33 is slidably provided on the two light rods 32. A clamping block 34 is assembled between two adjacent sliding shaft seats 33; the two clamping blocks 34 are arranged opposite to each other and a placement seat 38 is clamped therebetween.

[0025] In the present embodiment, in actual use, through the mutual movement and coordination of multiple components in the positioning assembly 3, the user places the bearing workpiece to be processed on the carrier plate 39, and at the same time rotates the rubber block 310, so that several rubber blocks 310 can surround the outside of the bearing workpiece. At the same time, the motor push rod 37 pushes the clamping block 34 radially, so that the two clamping blocks 34 can drive the clamping notches 35 to move in opposite directions until the two clamping notches 35 clamp the outside of the rubber block 310. At this time, the two clamping notches 35 clamp the rubber block 310 and the rubber block 310 surround the outside of the bearing workpiece, and finally the two clamping notches 35 clamp the outside of the bearing workpiece. Compared with the traditional bearing retainer load-bearing installation, the two clamping notches 35 that move in opposite directions can ensure that the bearing workpiece has higher stability during processing, and at the same time reduce the time of replacing the bearing retainer during bearing processing. The positioning assembly 3 can adapt and clamp bearings of various models and sizes, and the overall practicality is stronger.

[0026] Specifically, refer to Figure 1-2 The two clamping blocks 34 are provided with clamping notches 35 on opposite sides thereof. The two clamping notches 35 are arranged opposite to each other and are provided in a triangular shape.

[0027] In this embodiment, in actual use, the clamping notch 35 opened on the clamping block 34 and the triangular-shaped clamping notch 35 can provide better clamping force distribution, so that the bearing workpiece is more stable during the clamping process; this helps to maintain the stability of the geometric shape and position of the bearing workpiece and improve the processing accuracy. At the same time, the clamping block 34 with a triangular notch can provide better clamping force, reduce the risk of sliding and deviation during the clamping process, help ensure the safety of the bearing during the processing, and avoid accidents and damage caused by unstable clamping.

[0028] Specifically, refer to Figure 3-4 A carrying plate 39 is detachably provided on the upper end surface of the placement seat 38 through bolts, and an inner conical surface 391 is formed on the carrying plate 39 along its center.

[0029] In this embodiment, in actual assembly, the user can place the bearing workpiece in the inner conical surface 391. The conical setting of the inner conical surface 391 can reduce the wear on the bottom of the bearing during processing, thereby further improving the stability and processing yield of the bearing.

[0030] Specifically, refer to Figure 3-4 A positioning column 392 is vertically arranged at the center of the supporting plate 39, and the end of the positioning column 392 is arranged in a hemispherical shape.

[0031] In this embodiment, during use, the user can place the center of the bearing workpiece inside the positioning column 392 , so that the bearing can be preliminarily fixed outside the positioning column 392 .

[0032] Specifically, refer to Figure 3-4 A plurality of rubber blocks 310 are arranged around the center of the upper end surface of the carrier plate 39. Each rubber block 310 is arranged in an arc shape and is soft as a whole. One end of each rubber block 310 is rotatably arranged on the carrier plate 39 through a rotating shaft.

[0033] In this embodiment, during use, when the bearing is small and its diameter is smaller than the carrier plate 39, the user can rotate the rubber block 310 so that the rubber block 310 surrounds the outside of the bearing. At this time, when the two clamping blocks 34 move and drive the clamping notch 35 to clamp the outside of the bearing, the set clamping notch 35 can cooperate with the rubber block 310 to clamp the bearing together, so as to avoid the difficulty in stably clamping the smaller bearing. When the bearing is large and larger than the size of the carrier plate 39, the user can disassemble several rubber blocks 310 so that the bearing component can be carried alone on the carrier plate 39. At this time, the user can again use the clamping of the clamping notch 35 to achieve the clamping and positioning of the bearing component.

[0034] Specifically, refer to Figure 1-2 Two guide rod motors 36 are also arranged on the linear moving platform 21 . The output ends of the two guide rod motors 36 are arranged opposite to each other and are both connected to motor push rods 37 . The two motor push rods 37 extend respectively and are connected to the side surfaces of one of the clamping blocks 34 .

[0035] In this embodiment, in actual use, after the bearing is initially fixed on the outside of the supporting plate 39, the user can connect the two guide rod motors 36 to a power source, and then the user drives the motor push rod 37 to move by controlling the output end of the guide rod motor 36. At this time, the motor push rod 37 pushes the clamping block 34, so that the two clamping blocks 34 can drive the clamping notches 35 to move in opposite directions until the two clamping notches 35 clamp the outside of the rubber block 310.

[0036] The utility model of high stability bearing processing CNC lathe:

[0037] Step 1: In actual use, the user places the bearing workpiece to be processed on the carrier plate 39, and rotates the rubber blocks 310 so that a plurality of rubber blocks 310 can surround the outside of the bearing workpiece, and then positions the center of the bearing by the positioning column 392 disposed at the center of the carrier plate 39, thereby achieving preliminary positioning of the bearing workpiece;

[0038] Step 2: After the bearing is initially fixed on the outside of the carrier plate 39, the user connects the power supply to the two guide rod motors 36 again, and then the user drives the motor push rod 37 to move by controlling the output end of the guide rod motor 36. The motor push rod 37 pushes the clamping block 34, so that the two clamping blocks 34 drive the clamping notches 35 to move in opposite directions until the two clamping notches 35 clamp the outside of the rubber block 310. At this time, the two clamping notches 35 clamp the rubber block 310, and the rubber block 310 surrounds the outside of the bearing workpiece, and finally the two clamping notches 35 clamp the outside of the bearing workpiece. After the bearing workpiece is clamped on 29, the CNC machine tool body 1 can be driven to process the bearing workpiece.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
