Abstract
Description
Technical Field
[0001] This utility model relates to the field of guide rail auxiliary fixing technology, and in particular to a machine tool guide rail slider clamping device. Background Technology
[0002] The research and application of machine tool guide rail slider clamping devices stem from the upgraded requirements of machine tool processing for "precision stability" and "working condition adaptability," as well as the inherent defects of traditional guide rail mating methods in high-load, high-precision machining scenarios. In machine tool operation, the guide rail and slider, as the core motion pair, are responsible for driving the precise movement of components such as the worktable and tool post. Their mating clearance and relative stability directly determine the machining accuracy. Early machine tools (such as ordinary lathes and manual milling machines) mostly relied on the natural fit of the guide rail and slider or simple bolt fixing, without specially designed clamping structures. As industrial production transforms towards "high precision, high speed, and heavy load," these traditional methods have gradually exposed obvious shortcomings, driving the birth of dedicated clamping devices.
[0003] However, when adjusting manually with bolts, if too much force is applied based on experience, it can cause excessive pressure on the contact surface between the slider and the guide rail, which can easily aggravate the wear of the guide rail, increase the resistance to slider movement, cause "dragging" phenomenon, and even cause the drive motor to be overloaded. When the pressure is insufficient, it cannot counteract cutting vibration or inertial force, and the slider is prone to move along the guide rail, resulting in machining dimensional deviations.
[0004] Therefore, we provide a machine tool guide rail slider clamping device to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a machine tool guide rail slider clamping device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a machine tool guide rail slider clamping device, comprising a fixed adjustment auxiliary guide rail and an up-and-down fixed sliding and left-and-right clamping adjustment clamping mechanism, wherein the surface of the fixed adjustment auxiliary guide rail is provided with the up-and-down fixed sliding and left-and-right clamping adjustment clamping mechanism; The upper and lower fixed sliding and left and right clamping adjustment and pressing mechanism includes an upper and lower fixed auxiliary sliding component, a left and right threaded elastic auxiliary adjustment clamping component, and a top support load component. The upper and lower fixed auxiliary sliding component is provided on the surface of the fixed adjustment auxiliary guide rail. The left and right threaded elastic auxiliary adjustment clamping components are provided on both sides inside the upper and lower fixed auxiliary sliding component. The top support load component is provided on the upper side of the upper and lower fixed auxiliary sliding component.
[0007] Preferably, the upper and lower fixed auxiliary sliding assembly includes a fixed support collar, a bottom fixed support, an auxiliary rotating support rod, and a sleeved rubber rotating ball. The surface of the fixed adjustment auxiliary guide rail is provided with a fixed support collar. The bottom fixed support is fixedly connected to the upper and lower sides inside the fixed support collar. The auxiliary rotating support rod is rotatably sleeved on the inner side of the bottom fixed support. The surface of the auxiliary rotating support rod is sleeved with a sleeved rubber rotating ball.
[0008] Preferably, the left and right threaded elastic auxiliary adjustment clamping assembly includes a through-sleeve support rod, an internal threaded auxiliary sleeve, a damping support spring, an arc-shaped fitting auxiliary sliding washer, and a sleeve limiting spring. The through-sleeve support rod is through-sleevely sleeved on both sides of the fixed support collar. The external end of the through-sleeve support rod is threaded with an internal threaded auxiliary sleeve. The inner side of the internal threaded auxiliary sleeve is sleeved with a damping support spring at the connection point between it and the external end of the fixed support collar. The arc-shaped fitting auxiliary sliding washer is fixedly connected to the inner side of the through-sleeve support rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are: As shown in the figure, this utility model features two guide rails with spherical auxiliary sliding devices on both the upper and lower sides inside. During use, even when the adjusting clamping components at both ends are loose, the entire guide rail can still slide at the top. This allows for surface maintenance of the guide rail when not in use and facilitates sliding and repositioning, preventing scratches on the guide rail surface. During load processing, the internal threaded auxiliary sleeves at both ends are manually adjusted to ensure the internal arc-shaped auxiliary sliding pads adhere to the surface of the fixed adjusting auxiliary guide rail. Multiple springs on the surface allow the damping support spring and the sleeved limit spring to buffer the stress on the support panel during cutting, thus adaptively adjusting during cutting and ensuring the stability of the processing.

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.
[0013] Please see Figure 1-3 As shown, this utility model provides a technical solution: a machine tool guide rail slider clamping device, including a fixed adjustment auxiliary guide rail 1 and an up-and-down fixed sliding and left-and-right clamping adjustment clamping mechanism 2. The surface of the fixed adjustment auxiliary guide rail 1 is provided with the up-and-down fixed sliding and left-and-right clamping adjustment clamping mechanism 2. The upper and lower fixed sliding and left and right clamping adjustment clamping mechanism 2 includes an upper and lower fixed auxiliary sliding component 21, a left and right threaded elastic auxiliary adjustment clamping component 22, and a top support load component 23. The upper and lower fixed auxiliary sliding component 21 is provided on the surface of the fixed adjustment auxiliary guide rail 1. The left and right threaded elastic auxiliary adjustment clamping components 22 are provided on both sides inside the upper and lower fixed auxiliary sliding component 21. The top support load component 23 is provided on the upper side of the upper and lower fixed auxiliary sliding component 21.
[0014] Furthermore, the upper and lower fixed auxiliary sliding assembly 21 includes a fixed support collar 211, a bottom fixed support 212, an auxiliary rotating support rod 213, and a sleeved rubber rotating ball 214. The fixed support collar 211 is provided on the surface of the fixed adjustment auxiliary guide rail 1. The bottom fixed support 212 is fixedly connected to the upper and lower sides inside the fixed support collar 211. The auxiliary rotating support rod 213 is rotatably sleeved on the inner side of the bottom fixed support 212. The sleeved rubber rotating ball 214 is sleeved on the surface of the auxiliary rotating support rod 213. The sleeved rubber rotating ball 214 is laid on both the upper and lower sides inside the fixed adjustment auxiliary guide rail 1 to fit and assist in sliding operations. During use, even when the adjustment clamping components at both ends are loose, the entire slider can still slide at the top of the guide rail. On the one hand, it can maintain the surface of the guide rail when it is not in use, and on the other hand, it can facilitate sliding and return to its original position, preventing scratches on the guide rail surface.
[0015] Furthermore, the left and right threaded elastic auxiliary adjustment clamping assembly 22 includes a through-sleeve support rod 221, an internal threaded auxiliary sleeve 222, a damping support spring 223, an arc-shaped fitting auxiliary sliding washer 224, and a sleeved limiting spring 225.

An internal threaded auxiliary sleeve 222 is threadedly fitted to the outer end of the through-sleeve support rod 221. A damping support spring 223 is fitted to the inner side of the internal threaded auxiliary sleeve 222 at the point where it fits with the outer end of the fixed support ring 211. An arc-shaped fitting auxiliary sliding washer 224 is fixedly connected to the inner side of the through-sleeve support rod 221. A sleeved limiting spring 225 is sleeved at the connection between the auxiliary sliding pad 224 and the inner side of the fixed support collar 211. During the upper load processing, the internal threaded auxiliary sleeves 222 at both ends are manually adjusted so that the inner arc-shaped auxiliary sliding pad 224 is fitted to the surface of the fixed adjustment auxiliary guide rail 1. Through the multiple springs on its surface, during processing, the stress of cutting the support panel 231 will affect the sliding friction at the lower end. The damping support spring 223 and the sleeved limiting spring 225 can buffer according to the direction of stress, and thus make adaptive adjustments during cutting to ensure the stability of the processing.
[0016] Furthermore, the top support load assembly 23 includes a support panel 231 and auxiliary fastening bolts 232. The top of the fixed support collar 211 is provided with a support panel 231, and the support panel 231 is threadedly fixed to the lower fixed support collar 211 by the auxiliary fastening bolts 232 on the surface.
