Description

Technical Field

[0001] This utility model relates to the field of bearing tube pre-cutting technology, and in particular to a scribing device for pre-cutting bearing tubes. Background Technology

[0002] In the bearing manufacturing industry, bearing tubes are a key raw material, and the precision of their cutting and processing directly determines the quality and performance of the bearing. Pre-cutting and scribing is an important preliminary process for the cutting and processing of bearing tubes. Precise scribing can provide accurate guidance for subsequent cutting, ensuring that the cutting dimensions meet the design requirements, thereby guaranteeing the dimensional accuracy and assembly accuracy of each component of the bearing.

[0003] Currently, traditional methods have many limitations in the pre-cutting and scribing process of bearing tubes. Some small enterprises still use manual scribing, where workers use simple tools such as rulers and scribing needles to mark the surface of the bearing tubes based on their experience. However, manual operation is greatly affected by factors such as the worker's skill level and fatigue, making it difficult to guarantee the accuracy and consistency of the scribing. For example, when scribing long bearing tubes, manual measurement is prone to cumulative errors, leading to scribing deviations. Ultimately, this causes the length deviation of the cut bearing tube to exceed the allowable range, affecting bearing assembly and reducing the product qualification rate. Moreover, manual scribing is extremely inefficient and cannot meet the needs of large-scale industrial production.

[0004] To address this, a scribing device for pre-cutting bearing tubes is proposed. Summary of the Invention

[0005] The purpose of this invention is to solve the problems raised in the background art by proposing a scribing device for pre-cutting bearing tubes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A scribing device for pre-cutting bearing tubes includes a base, a fixing tube fixedly disposed on the top of the base, and a bearing tube clamping mechanism disposed inside the fixing tube.

[0008] The outer wall of the fixed tube is fixedly provided with a bearing, and the outer wall of the bearing is fixedly sleeved with a gear ring. The top of the fixed tube is fixedly provided with a motor, and the output shaft of the motor is fixedly provided with a gear, which meshes with the gear ring.

[0009] An adjusting rod is fixedly provided on the side wall of the gear ring. A mounting plate is fixedly provided at the end of the adjusting rod away from the gear ring, and a scribing inkjet head is detachably provided on the surface of the mounting plate.

[0010] Preferably, the bearing tube clamping mechanism includes electric push rods symmetrically fixed on both sides inside the fixed tube, and the moving ends of the two electric push rods are fixed with arc-shaped clamps.

[0011] Preferably, the inner walls of both arc-shaped clamps are provided with anti-slip textures.

[0012] Preferably, the adjusting rod includes a fixed sleeve fixedly disposed on the side wall of the gear ring, the fixed sleeve having a movable rod inside, and the outer wall of the fixed sleeve having a first bolt threaded on it, and the first bolt fixing the movable rod in place.

[0013] Preferably, the inner wall of the fixed sleeve has a square hole, and the moving rod is a square rod that matches the inner wall of the fixed sleeve.

[0014] Preferably, a mounting sleeve is fixedly provided on the side of the mounting plate, the marking inkjet head is located inside the mounting sleeve, and a second bolt is threaded on the side wall of the mounting sleeve, and the second bolt fixes the marking inkjet head in place.

[0015] Preferably, the motor is a servo motor, and the motor is electrically connected to an external controller.

[0016] Compared with the prior art, the present invention provides a scribing device for pre-cutting bearing tubes, which has the following advantages:

[0017] 1. The scribing device for pre-cutting bearing tubes uses an electric push rod (10) symmetrically fixed on both sides of the fixed tube (2) to push the arc-shaped clamping plate (11) to clamp the bearing tube by setting a bearing tube clamping mechanism. The inner side wall of the arc-shaped clamping plate (11) is provided with anti-slip texture (12), which effectively avoids the slippage of the bearing tube during the scribing process. Compared with manual scribing, which is greatly affected by the worker's skill level and fatigue, the accuracy of scribing is greatly improved, and the problem of the bearing tube length deviation exceeding the allowable range after cutting due to scribing deviation is reduced.

[0018] 2. The scribing device for pre-cutting bearing tubes uses a motor (5) to drive the gear (6) to mesh with the gear ring (4) and rotate, thereby driving the adjusting rod (7), the mounting plate (8) and the scribing inkjet head (9) to rotate around the bearing tube to scribing, thus realizing automated scribing operation. Compared with manual scribing using simple tools such as rulers and scribing needles, it greatly shortens the scribing time, meets the needs of large-scale industrial production, and reduces labor costs.

[0019] 3. The scribing device for pre-cutting bearing tubes has a length adjustment function through the design of the adjusting rod (7). By loosening the first bolt (15) and moving the moving rod (14) inside the fixed sleeve (13), the distance between the scribing inkjet head (9) and the center of the bearing tube can be changed, thereby realizing the adjustment of the radial position. This allows the device to adapt to the scribing requirements of bearing tubes of different sizes and specifications, thus improving the versatility of the device. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Reference Figure 1-3 A marking device for pre-cutting bearing tubes includes a base 1, a fixed tube 2 fixedly mounted on the top of the base 1, and a bearing tube clamping mechanism inside the fixed tube 2. The bearing tube clamping mechanism includes electric push rods 10 symmetrically fixed on both sides inside the fixed tube 2. The moving ends of the two electric push rods 10 are fixedly provided with arc-shaped clamping plates 11. The inner sidewalls of the two arc-shaped clamping plates 11 are provided with anti-slip textures 12. When the electric push rods 10 are activated, the moving ends of the electric push rods 10 extend and drive the arc-shaped clamping plates 11 to move towards the bearing tube, thereby clamping the bearing tube using the two arc-shaped clamping plates 11.

[0027] A bearing 3 is fixedly mounted on the outer wall of the fixed tube 2, and a gear ring 4 is fixedly mounted on the outer wall of the bearing 3. A motor 5 is fixedly mounted on the top of the fixed tube 2, and a gear 6 is fixedly mounted on the output shaft of the motor 5. The gear 6 meshes with the gear ring 4. The motor 5 is a servo motor and is electrically connected to an external controller, which can control the forward and reverse rotation of the motor 5 to avoid some pipe entanglement. The output shaft of the motor 5 drives the gear 6 to rotate. Since the gear 6 meshes with the gear ring 4, the gear ring 4 will rotate with the rotation of the gear 6. When the gear ring 4 rotates, the adjusting rod 7 fixed on its side wall will also rotate, so that the marking inkjet head 9 will make a circular motion around the bearing tube.

[0028] An adjusting rod 7 is fixedly mounted on the side wall of the gear ring 4. A mounting plate 8 is fixedly mounted on the end of the adjusting rod 7 away from the gear ring 4. A scribing inkjet head 9 is detachably mounted on the surface of the mounting plate 8. The adjusting rod 7 includes a fixing sleeve 13 fixedly mounted on the side wall of the gear ring 4. A moving rod 14 is provided inside the fixing sleeve 13. A first bolt 15 is threaded onto the outer wall of the fixing sleeve 13, and the first bolt 15 fixes the moving rod 14. The inner side wall of the fixing sleeve 13 has a square hole, and the moving rod 14 is designed to match the inner wall of the fixing sleeve 13. The square rod and its square structure prevent the moving rod 14 from rotating inside the fixed sleeve 13. The length of the moving rod 14 inside the fixed sleeve 13 can be adjusted by loosening the first bolt 15, so that the position of the marking inkjet head 9 can be adjusted. The mounting plate 8 is fixedly provided with a mounting sleeve 16, and the marking inkjet head 9 is located inside the mounting sleeve 16. The side wall of the mounting sleeve 16 is threaded with a second bolt 17, and the second bolt 17 fixes the marking inkjet head 9. The marking inkjet head 9 can be disassembled and assembled by loosening the second bolt 17.

[0029] In this utility model, the bearing tube is first placed inside the fixed tube 2, and the electric push rod 10 is started. The moving end of the electric push rod 10 extends and drives the arc-shaped clamping plate 11 to move towards the bearing tube. The bearing tube is clamped by the two arc-shaped clamping plates 11. The anti-slip texture 12 provided on the inner side wall of the arc-shaped clamping plate 11 can increase the friction and prevent the bearing tube from sliding during the scribing process, thus ensuring the scribing accuracy.

[0030] The operator starts the motor 5 by operating the controller. The output shaft of the motor 5 drives the gear 6 to rotate. Since the gear 6 is meshed with the gear ring 4, the gear ring 4 will rotate with the rotation of the gear 6. When the gear ring 4 rotates, the adjusting rod 7 fixed on its side wall will also rotate. The end of the adjusting rod 7 away from the gear ring 4 is fixed with a mounting plate 8. The mounting plate 8 is equipped with a scribing ink head 9. Therefore, the scribing ink head 9 will make a circular motion around the bearing tube. During the motion, the scribing ink head 9 sprays ink lines to scribble a pre-cut line on the surface of the bearing tube.

[0031] When the position of the scribing needs to be adjusted, the operator can loosen the first bolt 15. The adjusting rod 7 includes a fixed sleeve 13 fixedly set on the side wall of the gear ring 4. The fixed sleeve 13 is provided with a moving rod 14 inside. The first bolt 15 is threaded on the outer wall of the fixed sleeve 13. The moving rod 14 is moved inside the fixed sleeve 13 to change the length of the adjusting rod 7, thereby adjusting the distance between the scribing inkjet head 9 and the center of the bearing tube, realizing the adjustment of the radial position. The inner side wall of the fixed sleeve 13 adopts a square hole, and the moving rod 14 adopts a matching square rod to prevent the moving rod 14 from rotating inside the fixed sleeve 13, ensuring the accuracy of the adjustment, thereby enabling the adjustment of the pre-cut position of the bearing tube.

[0032] 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.
