Description

Technical Field

[0001] This utility model discloses a cutting guide mechanism for ball bearing slide rail processing, which relates to the field of slide rail cutting and processing technology. Background Technology

[0002] Ball bearing guideway cutting refers to the process of cutting and machining ball bearing guideways (also called rolling guideways, linear guideways, etc.). Ball bearing guideways are widely used in mechanical equipment, providing high-precision linear guidance, and are commonly found in automation equipment, precision instruments, machine tools, and other fields. Cutting ball bearing guideways is a crucial process step, typically involving length adjustment and cut surface treatment. Using a band saw or circular saw is one of the most common methods for cutting ball bearing guideways. This method is simple and economical, suitable for mass production. During the cutting process, special attention must be paid to material fixation, control of cutting accuracy, and the quality of the cut surface to ensure that the final ball bearing guideway meets the usage requirements.

[0003] Ball bearing guideways are typically cut using a circular saw. In automated production, they require linear guidance. However, after being guided and fixed, the clamping forces on ball bearing guideways of different sizes vary. Furthermore, during circular sawing, the ball bearing guideway at the cutting point experiences significant force, which can cause wobbling or slight displacement during cutting. This reduces machining accuracy and may increase the defect rate. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting guide mechanism for ball slide rail processing, which can guide and firmly clamp the cutting part of the guide rail when cutting ball slide rails of different sizes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting guide mechanism for processing ball bearing slide rails, comprising a cutting machine, a conveyor mounted on the cutting machine for conveying the ball bearing slide rail to be processed, two sets of pressing and guiding mechanisms mounted on the conveyor for pressing and guiding the conveyed ball bearing slide rail, and a cutting stabilizing mechanism mounted on the cutting machine; the cutting stabilizing mechanism includes a fixed frame, the fixed frame being fixedly connected to the cutting machine, a cutting protective cover being slidably mounted above the fixed frame, and a limiting structure being mounted above the cutting protective cover, with two sets of limiting structures installed on both sides of the cutting protective cover.

[0006] Preferably, the limiting structure is provided with a bracket, a transmission block is slidably installed inside the bracket, and passive blocks are slidably installed on both sides of the transmission block, with the passive blocks slidably connected to the bracket.

[0007] Preferably, the pressure-holding guide mechanism is driven by a cylinder, and the cutting and stabilizing mechanism is driven by a cylinder.

[0008] Preferably, the passive block has inclined surfaces on both sides, and the connection between the passive block and the transmission block is also inclined.

[0009] Preferably, a telescopic shaft is provided at the upper end of the transmission block, a large spring is installed on the outside of the telescopic shaft, and the telescopic shaft is fixedly connected to the bracket.

[0010] Preferably, the lower end of the transmission block is provided with an abutment head, and the abutment head is provided with an anti-slip groove to increase the holding friction.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the ball slide rail to be processed is conveyed to the bottom of the pressing and guiding mechanism by the conveyor and the roller. The pressing and guiding mechanism fixes and guides the ball slide rail. The cutting and stabilizing mechanism provides final stabilizing clamping for the ball slide rail. The passive block slides horizontally in the bracket, and the transmission block slides vertically in the bracket. The cylinder drives the bracket to press down. After the lower end face of the transmission block contacts the upper surface of the ball slide rail, it slides upward in the bracket. At the same time, due to the inclined surface design, the transmission block will pull the two sets of passive blocks to move towards the center to clamp until they contact the two side surfaces of the ball slide rail, thereby reducing the vibration of the ball slide rail during cutting and reducing the offset during cutting, and stabilizing the ball slide rail.

[0017] 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, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples:

[0019] like Figure 1 As shown, a cutting and guiding mechanism for processing ball slide rails includes a cutting machine 1, a conveyor 2 mounted on the cutting machine 1 for conveying the ball slide rail to be processed, two sets of pressing and guiding mechanisms 3 mounted on the conveyor 2 for pressing and guiding the conveyed ball slide rail, and a cutting stabilizing mechanism 4 mounted on the cutting machine 1. The pressing and guiding mechanism 3 is driven by a cylinder, and the cutting stabilizing mechanism 4 is driven by a cylinder.

[0020] In actual operation, the conveyor 2 transports the ball slide rail to be processed to the lower part of the pressing and guiding mechanism 3 through the roller. The pressing and guiding mechanism 3 fixes and guides the ball slide rail. The specific working principle can be referred to a guiding and positioning fixture with patent number CN221186142U. Small push plates not higher than the ball slide rail are set on both sides to position and clamp the ball slide rail. Then, a cylinder-driven roller pressing plate is set at the top to press the upper surface of the ball slide rail and enable it to continue to be transported to the lower part of the cutting stabilizing mechanism 4 on the cutting machine 1. The cutting stabilizing mechanism 4 performs a final stabilizing clamp on the ball slide rail to reduce the vibration of the ball slide rail during cutting and reduce the offset during cutting, and stabilize the ball slide rail.

[0021] like Figure 2 As shown, the cutting stabilizing mechanism 4 includes a fixed frame 42, which is fixedly connected to the cutting machine 1. A cutting protective cover 43 is slidably installed above the fixed frame 42. A limiting structure 41 is installed above the cutting protective cover 43. Two sets of limiting structures 41 are provided and are installed on both sides of the cutting protective cover 43.

[0022] Because the circular saw cuts along the side of the ball bearing slide rail during cutting, the cutting part is subjected to great cutting force, which causes vibration during cutting. This results in slight deformation and displacement of the cutting part, leading to more burrs on the cut and defects in the product. The function of the limiting structure 41 is to stabilize and fix the ball bearing slide rails on both sides of the circular saw during cutting, reducing its displacement and vibration. The function of the cutting guard 43 is to prevent sparks from flying during cutting, which could cause injury to personnel or equipment. In actual operation, the cylinder drives the limiting structure 41 and the cutting guard 43 to press down, and the limiting structure 41 fixes the ball bearing slide rail.

[0023] like Figure 3 As shown, the limiting structure 41 is provided with a bracket 411, a transmission block 412 is slidably installed in the bracket 411, and passive blocks 413 are slidably installed on both sides of the transmission block 412. The passive blocks 413 are slidably connected to the bracket 411.

[0024] The passive block 413 has inclined surfaces on both sides (not shown in the figure), and the connection between the passive block 413 and the transmission block 412 is also set as an inclined surface.

[0025] In actual operation, the passive block 413 slides horizontally within the bracket 411, and the transmission block 412 slides vertically within the bracket 411. The cylinder drives the bracket 411 to press down. After the lower end face of the transmission block 412 contacts the upper surface of the ball slide rail, it slides upward within the bracket 411. At the same time, due to the inclined surface design, the transmission block 412 will pull the two sets of passive blocks 413 to move towards the center and clamp them until they contact the two sides of the ball slide rail.

[0026] The upper end of the transmission block 12 is provided with a telescopic shaft 417, and a large spring 418 is installed on the outside of the telescopic shaft 417. The telescopic shaft 417 is fixedly connected to the bracket 411.

[0027] The coordinated movement of the telescopic shaft 417 and the large spring 418 can make the structure stable when the transmission block 412 slides. At the same time, the transmission block 412 provides a pressing force when pressing. When the work is finished, the large spring 418 rebounds, allowing the mechanism to return to its original position quickly.

[0028] The lower end of the transmission block 412 is provided with an abutment 416, and the abutment 416 is provided with an anti-slip groove (not shown in the figure) to increase the holding friction.

[0029] The function of the contact head 416 is to abut against the upper surface of the ball slide rail and trigger the movement of the transmission block 412;

[0030] When the limiting structure 41 is pressing and clamping, ball slide rails of different sizes need to be processed by the same machine. This may result in problems such as insufficient clamping force due to excessive or insufficient size. Therefore, the lower end of the passive block 413 is slidably installed with a limiting block 415. Several sets of small springs 414 are provided inside the limiting block 415 and the passive block 413.

[0031] Its function is to allow the transmission block 412 to continue moving even when the inner surface of the limiting block 415 has already contacted both sides of the ball slide rail. The transmission block 412 continues to rise, the passive block 413 continues to press left and right, the small spring 414 is compressed, and the limiting block 415 continues to press both sides of the ball slide rail. The small spring 414 provides a pressing force, making the clamping more stable and the application range wider.

[0032] In summary, the ball bearing guide rail to be processed is conveyed to the bottom of the holding and guiding mechanism 3 by the conveyor 2 through the roller. The holding and guiding mechanism 3 fixes and guides the ball bearing guide rail. The cutting and stabilizing mechanism 4 provides final stabilizing clamping for the ball bearing guide rail. The passive block 413 slides horizontally in the bracket 411, and the transmission block 412 slides vertically in the bracket 411. The cylinder drives the bracket 411 to press down. After the lower end face of the transmission block 412 contacts the upper surface of the ball bearing guide rail, it slides upward in the bracket 411. At the same time, due to the inclined surface design, the transmission block 412 will pull the two sets of passive blocks 413 to move towards the center to clamp until they contact the two sides of the ball bearing guide rail, thereby reducing the vibration of the ball bearing guide rail during cutting and reducing the offset during cutting, and stabilizing the ball bearing guide rail.

All technical solutions within this concept are within the scope of protection of this application. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of this application should also be considered within the scope of protection of this application.
