Description

Technical Field

[0001] This utility model relates to the field of precision machining technology for special parts of forestry machinery, and in particular to a machining device for connecting bearings for logging loaders. Background Technology

[0002] With the comprehensive upgrading of intelligent forestry equipment, in the process of preventive maintenance of core components of large logging machines, it is necessary to carry out non-destructive testing and precise replacement of high-load joint bearings, which requires the use of processing equipment. In practical use, similar processing devices still have many defects, such as: traditional processing devices lack multi-dimensional collaborative positioning capabilities, single-direction limiting makes it difficult to guarantee the concentricity of the inner and outer rings of the bearing, and the concentration of assembly stress can easily cause damage to the raceway. At the same time, the manual assembly of traditional processing devices is inefficient and of unstable quality. It relies on the operator's experience to adjust the ball clearance, which is labor-intensive and has poor batch consistency. Therefore, it is necessary to design a connecting bearing processing device for logging loaders. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a connecting bearing processing device for logging loaders.

[0004] This utility model is achieved using the following technical solution: a connecting bearing processing device for a logging loader, comprising an installation assembly, the installation assembly including an installation plate, the installation plate having an installation cavity inside, and a guide rail fixedly connected to the inner wall of the installation cavity, and further comprising: The front and rear adjustment assembly includes a movable seat that is slidably mounted on the outer surface of the guide rail. The top of the movable seat is provided with a movable frame via a lifting cylinder, and the bottom of the movable frame is fixedly connected to an inner circle limiting seat via a limiting wheel. The limiting component includes an outer circular limiting ring fixedly connected inside the mounting plate, and an adjusting cover is slidably mounted on the top of the outer circular limiting ring via a spring damper.

[0005] As a further improvement to the above solution, a push cylinder is fixedly connected to the top of the mounting plate, and a movable frame is fixedly connected to the output end of the push cylinder.

[0006] The above technical solution achieves precise displacement control of the inner ring bearing by rigidly connecting the cylinder and the moving frame to form a linear transmission chain. This ensures lossless transmission of axial driving force.

[0007] As a further improvement to the above solution, a movable seat is slidably mounted on the top of the guide rail, and a lifting cylinder is fixedly connected to the top of the movable seat.

[0008] Through the above technical solution, the guide rail provides a low-friction guiding reference surface for the moving seat, and together with the vertical movement of the lifting cylinder, it constructs a stable support platform in a two-dimensional plane, thereby improving the system's resistance to eccentric loads.

[0009] As a further improvement to the above solution, the output end of the lifting cylinder is fixedly connected to the bottom of the movable frame, and the bottom of the movable frame is fixedly connected to a limit wheel.

[0010] Through the above technical solution, the limiting wheel, as a kinematic pair constraint element, not only restricts lateral offset but also allows free axial sliding. It works with the guide groove to form a self-correcting mechanism, ensuring directional consistency during the assembly process.

[0011] As a further improvement to the above solution, a limiting groove is formed inside the outer circular limiting ring, and a spring damper is fixedly connected to the inner wall of the limiting groove.

[0012] Through the above technical solution, the limiting groove provides a linear motion track for the adjustment cover. Combined with the elastic preload of the spring damper, it achieves adaptive positioning compensation under dynamic balance and improves the repeatability of positioning accuracy.

[0013] As a further improvement to the above solution, an adjustment cover is fixedly connected to the bottom of the spring damper, and the adjustment cover is slidably installed inside the limiting groove.

[0014] By using the above technical solution, the damping characteristics of the sliding spring damper in the limiting groove of the adjustment cover are adjusted to form an overload protection mechanism. When abnormal resistance is encountered, the buffer stroke is automatically triggered to prevent hard collision damage to the workpiece.

[0015] As a further improvement to the above solution, operating holes are provided on both sides inside the adjusting cover, and a guide groove is provided at the center inside the adjusting cover, with a limit wheel slidably installed inside the guide groove.

[0016] Through the above technical solution, the operating hole provides a channel for manual intervention to facilitate ball filling, and the guide groove and the limit wheel work together to form a dual guidance system of vision and touch, which reduces the difficulty of operation and improves the assembly success rate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model utilizes a composite positioning structure consisting of a mounting plate, an outer circle limiting ring, a lifting cylinder, an adjusting cover, an inner circle limiting seat, and a spring damper. This structure drives the bearing assembly to achieve precise alignment of both the inner and outer circles, thereby maintaining absolute concentricity during the machining process. The spring damper provides dynamic buffering during vertical movement, effectively absorbing mechanical impact energy, protecting precision components from damage, and storing potential energy for the reset action.

[0018] This invention utilizes a linkage guiding system consisting of a cylinder, a moving frame, a limiting wheel, a guide groove, and a guide rail to drive the inner ring bearing to smoothly slide along a predetermined trajectory towards the outer ring bearing mating part. This achieves the optimization of the ball assembly path and the automatic correction of radial deviation. The design establishes a constraint equation using the cooperation relationship between the limiting wheel and the guide groove, and forms a closed-loop control chain through the motion compensation of the lifting cylinder by the guide rail, making the assembly process both highly efficient and highly precise.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0022] Please combine Figure 1-5 This embodiment of a connecting bearing processing device for a logging loader includes a mounting assembly 1. The mounting assembly 1 includes a mounting plate 101, and a mounting cavity 102 is formed inside the mounting plate 101. A guide rail 103 is fixedly connected to the inner wall of the mounting cavity 102. The device also includes: The front and rear adjustment assembly 2 includes a movable seat 206 that is slidably mounted on the outer surface of the guide rail 103. The top of the movable seat 206 is provided with a movable frame 202 via a lifting cylinder 205. The bottom of the movable frame 202 is fixedly connected to an inner circle limit seat 204 via a limit wheel 203. The limiting component 3 includes an outer circular limiting ring 301 fixedly connected inside the mounting plate 101, and an adjusting cover 304 is slidably mounted on the top of the outer circular limiting ring 301 via a spring damper 303.

[0023] A push cylinder 201 is fixedly connected to the top of the mounting plate 101, and a movable frame 202 is fixedly connected to the output end of the push cylinder 201.

[0024] A movable seat 206 is slidably mounted on the top of the guide rail 103, and a lifting cylinder 205 is fixedly connected to the top of the movable seat 206.

[0025] The output end of the lifting cylinder 205 is fixedly connected to the bottom of the movable frame 202, and the bottom of the movable frame 202 is fixedly connected to the limit wheel 203.

[0026] The outer circular limiting ring 301 has a limiting groove 302 inside, and a spring damper 303 is fixedly connected to the inner wall of the limiting groove 302.

[0027] An adjusting cover 304 is fixedly connected to the bottom of the spring damper 303, and the adjusting cover 304 is slidably installed inside the limiting groove 302.

[0028] The adjustment cover 304 has operation holes 305 on both sides inside, and a guide groove 306 is provided in the center of the adjustment cover 304. A limit wheel 203 is slidably installed inside the guide groove 306.

[0029] The cylinder 201 is pushed to generate axial thrust, which drives the moving frame 202 to make horizontal displacement along the linear guide rail. During this process, the limit wheel 203 slides synchronously along the guide groove 306 to form a compound motion trajectory. This linkage mechanism is achieved through the coordinated action of the guide rail 103 and the lifting cylinder 205.

[0030] The implementation principle of the connecting bearing processing device for a logging loader in this application embodiment is as follows: In the clamping and positioning stage, after the mounting plate 101 is accurately fixed to the end effector of the robotic arm, it is controlled by the drive unit to move along the preset trajectory until the outer circle limit ring 301 is accurately aligned with the outer diameter contour of the bearing to be processed. At this time, the lifting cylinder 205 is started and pushes the moving frame 202 to make a vertical descent movement. During this process, the adjusting cover 304 is guided to slide smoothly along the limit groove 302, driving the inner circle limit seat 204 to accurately reach the predetermined position at the top of the inner ring of the bearing. The spring damper 303 can provide buffer protection to prevent hard impact during the descent stage and store potential energy for the subsequent reset action. Once the double-limiting structure of the inner and outer circles is in place, the outer circle limiting ring 301 and the inner circle limiting seat 204 can ensure that the bearing assembly maintains absolute concentricity. At this time, the operator can perform ball assembly operations through the operating hole 305. During the ball installation stage, the cylinder 201 is pushed to generate axial thrust, which drives the moving frame 202 to make horizontal displacement along the linear guide rail. During this process, the limiting wheel 203 slides synchronously along the guide groove 306 to form a compound motion trajectory. This linkage mechanism, through the synergistic effect of the guide rail 103 and the lifting cylinder 205, ensures that the inner circle limiting seat 204 drives the inner ring bearing to slide smoothly to the joint of the outer circle bearing, and eliminates radial deviation through the guiding effect of the limiting wheel, ensuring that the ball can enter the assembly position along the optimal path.

[0031] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
