Description
Technical Field
[0001] This utility model relates to the field of ball guide technology, specifically a ball guide assembly. Background Technology
[0002] With the increasing demand for high-precision and high-efficiency equipment in modern industry and manufacturing, ball bearing assemblies, as a key mechanical transmission and positioning component, have been widely used in various mechanical equipment. Through high-precision rolling motion, ball bearing assemblies replace sliding friction, thus ensuring high load-bearing capacity while providing smooth, low-friction operation. They are widely used in machine tools, automated equipment, precision instruments, logistics and transportation systems, and other applications requiring precise positioning and movement.
[0003] Existing ball bearing guide assemblies still face several technical bottlenecks in practical applications. Firstly, under prolonged high-load or high-speed operation, the contact surfaces between the balls and the rails are prone to wear, leading to a gradual decrease in guide accuracy and affecting equipment operational stability. Secondly, in traditional structural designs, the rigid connections and buffering between components are insufficient, easily causing vibration and noise during high-speed movement, which not only deteriorates the working environment but may also interfere with precision instruments. Furthermore, existing guide assemblies have limitations in terms of deformation resistance and wear resistance, especially the mating components between the middle and inner rails, which lack effective reinforcement. After long-term use, these components are prone to increased clearance or deformation, further exacerbating frictional wear.
[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a ball guide assembly. Utility Model Content
[0005] The purpose of this invention is to provide a ball bearing guide assembly to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A ball guide assembly technical solution includes:
[0008] The outer casing has an internal outer casing stop insert and a steel ball strip; one end of the outer casing is fixed to the front bracket by a screw with a tapered head.
[0009] The back panel connects to the outer shell and is equipped with cabinet fixing screws and washers.
[0010] The telescopic plate is connected to the rear bracket via a telescopic plate spring and a buffer sheet, and the rear bracket is fixed by rear bracket screws and fixing screws.
[0011] The middle rail includes a ball-removing bracket spring piece, a stainless steel straight bottom piece, a middle rail rubber straight bottom piece, a steel ball-removing bracket, and a middle rail ball strip baffle. The middle rail is connected to the spring through a middle rail swing buckle.
[0012] The inner rail is equipped with a locking spring, an inner rail sheet metal part, and an inner rail sheet metal part spring. The inner rail sheet metal part is fixed by sheet metal part rivets.
[0013] As a preferred technical solution, the outer shell includes a zinc alloy outer shell component, with a frame and metal support structure on both sides.
[0014] As a preferred technical solution, a stainless steel straight bottom component is provided between the steel ball bearing bracket of the middle rail and the rubber straight bottom component of the middle rail to enhance the wear resistance and guiding accuracy of the middle rail.
[0015] As a preferred technical solution, a buffer spring is provided between the telescopic plate and the rear support to reduce vibration and noise during high-speed operation.
[0016] As a preferred technical solution, the inner rail's clamping box spring and the inner rail sheet metal are elastically connected by the inner rail sheet metal spring to achieve stable extension and retraction of the inner rail.
[0017] As a preferred technical solution, both the front bracket and the rear bracket are fixed to the outer shell by zinc alloy parts of the front bracket and zinc alloy parts of the outer shell, so as to improve the rigidity and deformation resistance of the overall structure.
[0018] As a preferred technical solution, a steel ball bearing strip 1 and a steel ball bearing strip 2 are provided between the middle rail and the inner rail to reduce friction loss through rolling contact.
[0019] As a preferred technical solution, the outer shell retaining insert cooperates with the middle rail bead retaining rubber to limit the movement range of the middle rail.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] This invention relates to a ball bearing guide assembly, significantly improving its wear resistance, guiding accuracy, and deformation resistance. The outer shell utilizes zinc alloy components and a metal support structure, enhancing overall rigidity and effectively resisting deformation during long-term use. The middle rail section, with the addition of a stainless steel straight-bottom component, further strengthens its wear resistance, ensuring the long-term stability of the guide's guiding accuracy. The buffer spring design between the telescopic plate and the rear support effectively reduces vibration and noise during high-speed operation, improving the working environment. The stable telescopic structure of the inner rail, through the elastic connection between the locking plate and the inner rail sheet metal, achieves precise positioning and smooth movement. Furthermore, the fixing method of the front and rear supports, as well as the rolling contact design between the middle and inner rails, all contribute to reducing frictional loss and improving operating efficiency. This invention, while overcoming existing technical bottlenecks, provides a reliable transmission and positioning solution for high-precision, high-efficiency mechanical equipment.
