Description

Technical Field

[0001] This utility model relates to the field of bushing press-fitting technology, and in particular to a bushing press-fitting machine. Background Technology

[0002] In the field of mechanical manufacturing, the assembly of bushings and shafts is a common and critical step. Traditional bushing assembly methods have many drawbacks, such as low efficiency and difficulty in ensuring assembly quality. Problems such as improper bushing assembly and uneven stress often occur, which in turn affect the overall performance and service life of mechanical equipment. Therefore, bushing press-fitting machines have emerged.

[0003] The bushing press machine mainly consists of a machine body, power unit, control unit, and press mechanism. During operation, the shaft and bushing are placed on the positioning device, and various parameters are set by the control unit. The power unit drives the press head to press down, and the bushing is pressed onto the shaft smoothly and accurately according to the set pressure and stroke.

[0004] Current bushing press-fitting machines cannot quickly and accurately adapt to bushings of different sizes and position them properly, resulting in a long preparation time before press-fitting. In mass production, this can seriously slow down the entire production process and reduce production efficiency. Therefore, a bushing press-fitting machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a bushing press-fitting machine, which aims to improve the problem in the prior art that it is impossible to quickly and accurately adapt to bushings of different sizes and to position the bushings.

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

[0007] A bushing press-fitting machine includes a housing, a platform fixedly connected to the outside of the housing, a positioning mechanism for positioning inside the platform, a pressing mechanism for press-fitting inside the housing, a support plate fixedly connected to the outside of the housing, and a flow control mechanism outside the support plate.

[0008] The positioning mechanism includes a motor, which is externally and fixedly connected to the inside of the platform. A rotating rod is fixedly connected to the drive end of the motor. A transmission rod is rotatably connected to both sides of the rotating rod. A slider is rotatably connected to the outside of the two transmission rods. A positioning clamp is fixedly connected to the top of the two sliders.

[0009] As a further description of the above technical solution:

[0010] The top of the shelf is provided with a sliding groove, and the outside of the slider is slidably connected to the inside of the sliding groove;

[0011] As a further description of the above technical solution:

[0012] The stamping mechanism includes a cylinder, the cylinder is fixedly connected to the top of the housing, and a lower pressure plate is fixedly connected to the driving end of the cylinder.

[0013] As a further description of the above technical solution:

[0014] The control mechanism includes a fixed plate, which is fixedly connected to the outside of the support plate. Two rotating columns are rotatably connected inside the fixed plate. Limit rod one and limit rod two are fixedly connected to the outside of the two rotating columns respectively. A transmission gear and a driven gear are fixedly connected to the outside of the limit rod one and the limit rod two respectively. The transmission gear and the driven gear are meshed. A motor two is fixedly connected to the bottom end of one of the rotating columns.

[0015] As a further description of the above technical solution:

[0016] A support rod is fixedly connected to the bottom end of the fixing plate, and the bottom end of the support rod is fixedly connected to the outside of the housing.

[0017] As a further description of the above technical solution:

[0018] The bottom end of the second motor is fixedly connected to the outside of the housing, and a conveyor belt is provided on the outside of the support plate;

[0019] As a further description of the above technical solution:

[0020] The top of the conveyor belt and the platform are provided with bushing blocks, and the positioning clamp is arc-shaped.

[0021] As a further description of the above technical solution:

[0022] The lower pressure plate is slidably connected to the inside of the housing, and the outside of the bushing block is in contact with the outside of the two positioning clamps.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the sliding block slides inside the groove, enabling the positioning clamp to quickly position the bushing. The positioning clamp is mainly arc-shaped, which guides the bushing to the top center of the platform and restricts its position, ensuring that the lower pressure plate presses the bushing consistently each time, thus guaranteeing the quality requirements of the bushing press.

[0025] 2. In this utility model, the meshing connection of the transmission gear and the driven gear allows the first and second limiting rods to alternately limit the movement, ensuring that only one bushing is at the top of the platform at any given time. This achieves precise flow control of the bushing blocks, avoids the chaos and operational difficulties caused by multiple bushing blocks arriving at the top of the platform simultaneously, and ensures that the bushing blocks enter the pressing position in an orderly manner. This provides good working conditions for subsequent pressing operations and ensures the continuity and efficiency of the entire bushing pressing process. Attached Figure Description

[0032] 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, those skilled in the art who have not made any innovative embodiments are all within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 The present invention provides an embodiment of a bushing press-fitting machine, comprising a housing 1, which serves as the main support structure of the entire press-fitting machine and provides a stable installation base for subsequent components. A platform 2 is fixedly connected to the outside of the housing 1. The platform 2 is used to place the bushing block 8 to be press-fitted. The position of the platform 2 is designed to facilitate operation by the operator. The platform 2 is equipped with a positioning mechanism for positioning. This positioning mechanism can accurately determine the position of the bushing block 8 and ensure the accuracy of the press-fitting.

[0034] The positioning mechanism includes a motor 3, which is externally and securely fixed to the inside of the shelf 2, providing power support for the positioning action. A rotating rod 4 is fixedly connected to the drive end of the motor 3. When the motor 3 starts, the rotating rod 4 rotates accordingly. Transmission rods 5 are rotatably connected to both sides of the rotating rod 4. The rotation of the rotating rod 4 drives the transmission rods 5 to move accordingly. Slider 6 is rotatably connected to the outside of each transmission rod 5. The movement of the transmission rods 5 pushes the slider 6 to move. Positioning clamps 9 are fixedly connected to the top of each slider 6. The movement of the slider 6 drives the positioning clamps 9 to move synchronously. The top of the 2 is provided with a slide groove 7. The outside of the slider 6 slides inside the slide groove 7. The slide groove 7 provides guidance for the movement of the slider 6, ensuring that the positioning clamp 9 can move accurately to the designated position. When the bushing block 8 slides to the top of the platform 2, the motor 3 can be started. The motor 3 will drive the rotating rod 4 to rotate, so that the two transmission rods 5 will pull the slider 6 to slide inside the slide groove 7 respectively, thereby realizing the precise positioning of the bushing block 8 by the two positioning clamps 9. Through this fast limiting mechanism, the position of the bushing block 8 is consistent each time it is pressed, thus ensuring the quality of the product after pressing.

[0035] The housing 1 is equipped with a pressing mechanism for press fitting. The pressing mechanism is the key part for press fitting the bushing block 8 with other components (such as bearings). The pressing mechanism includes a cylinder 10, which is fixedly connected to the top of the housing 1 to provide strong power for press fitting. The driving end of the cylinder 10 is fixedly connected to a lower pressure plate 11. When the cylinder 10 is started, the driving end pushes the lower pressure plate 11 downward to realize the press fitting operation of the bushing block 8 and related components. The housing 1 is fixedly connected to a support plate 13, which serves to support and connect components such as the control mechanism. The support plate 13 is equipped with a flow control mechanism on its exterior. This control mechanism can effectively control the number and rhythm of bushing blocks 8 entering the press fitting stage to ensure that the press fitting process is carried out in an orderly manner.

[0036] Reference Figure 1 , Figure 2 and Figure 4The control mechanism includes a fixed plate 14, which is externally fixedly connected to the support plate 13, providing an installation platform for the components of the control mechanism. Two rotating columns 15 are rotatably connected inside the fixed plate 14. The rotating columns 15 can rotate flexibly within the fixed plate 14, providing a rotational basis for subsequent limit actions. Limit rod 18 and limit rod 2 19 are fixedly connected to the outside of the two rotating columns 15, respectively. The rotation of the two rotating columns 15 will drive the limit rod 18 and limit rod 2 19 to rotate synchronously. A transmission gear 16 and a driven gear 17 are fixedly connected to the outside of the limit rod 18 and limit rod 2 19, respectively. The transmission gear 16 and the driven gear 17 are meshed. Through this gear meshing transmission, the coordinated rotation of the two rotating columns 15 is realized.

[0037] One of the rotating columns 15 has a motor 20 fixedly connected to its bottom end. The motor 20 provides the power source for the operation of the entire control mechanism. The bottom end of the fixed plate 14 has a support rod 21 fixedly connected to its bottom end. The bottom end of the support rod 21 is fixedly connected to the outside of the housing 1. The support rod 21 plays the role of stabilizing the fixed plate 14 and ensuring the stability of the control mechanism during operation. The bottom end of the motor 20 is fixedly connected to the outside of the housing 1 to ensure the installation stability of the motor 20. A conveyor belt 12 is provided on the outside of the support plate 13. The conveyor belt 12 is used to transport the bushing block 8 from the storage location to the vicinity of the platform 2. The top of the conveyor belt 12 and the platform 2 is provided with the bushing block 8. The bushing block 8 is the object to be pressed. The positioning clamp 9 has an arc shape. This arc design can better fit the shape of the bushing block 8 and guide the bushing block 8 so that the bushing block 8 reaches the designated position.

[0038] Working principle: When the operator needs to press the bushing block 8, the bushing block 8 is conveyed by the conveyor belt 12. At this time, the rotation of the second motor 20 can be controlled by the program. When the second motor 20 rotates, it will drive the rotating column 15 to rotate, thereby causing the transmission gear 16 and the driven gear 17 to rotate. This causes the two rotating columns 15 to drive the first limit rod 18 and the second limit rod 19 to rotate respectively, so that the first limit rod 18 and the second limit rod 19 alternately restrict the position of the bushing block 8, thus ensuring that only one bushing block 8 slides to the top of the platform 2 for pressing at a time. Through mechanical flow control, the normal operation of the pressing process is ensured, reducing manpower consumption and improving processing efficiency.

[0039] When the bushing block 8 slides to the top of the platform 2, the motor 3 can be started. The motor 3 will drive the rotating rod 4 to rotate, so that the two transmission rods 5 will pull the slider 6 to slide inside the slide groove 7, thereby positioning the bushing block 8 with the two positioning clamps 9. At this time, bearings and other components can be placed outside the bushing block 8. Then, the cylinder 10 is started to perform the pressing operation. Through the rapid limiting mechanism, the position of the bushing block 8 is kept consistent each time it is pressed, thus ensuring the quality of the product after pressing.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
