Description

Technical Field

[0001] This utility model belongs to the field of CNC lathe technology, specifically relating to a CNC lathe slide saddle with a built-in balance cylinder. Background Technology

[0002] In machine tool processing, the slide saddle is a crucial component, primarily used to support workpieces and tools, and playing a positioning and supporting role during machining. The main components of the slide saddle include the bed, slide, guide rails, and slide adjustment mechanism. The bed is the main body of the machine tool, typically made of cast iron or steel plate, possessing sufficient rigidity and stability. The slide is a movable worktable mounted on the bed, capable of sliding back and forth along the guide rails. The guide rails are a key part of the machine tool slide saddle, providing sufficient support and positioning force to enable precise movement and positioning of the slide. The slide adjustment mechanism is used to adjust the position and angle of the slide on the guide rails to meet different machining needs.

[0003] Existing slides are prone to vibration and deformation due to inertia or cutting forces during high-load or high-speed machining, leading to a decrease in accuracy. Most slides use external hydraulic or pneumatic balancing systems, which have problems such as large size, slow response, and complex maintenance. To address these issues, we propose a CNC lathe slide with an internal balancing cylinder. Utility Model Content

[0006] Preferably, limit blocks are symmetrically fixedly installed on both sides of the top of the sliding saddle body, and an installation hole is provided through the middle of one end surface of the inner side of the sliding groove.

[0007] Preferably, a piston rod is slidably inserted through the inner side of the mounting hole, and one end of the piston rod is fixedly connected to the output end of the balance cylinder.

[0008] Preferably, the surface of the sliding saddle body has a positioning groove at one end of the limiting block, and the positioning protrusion and the positioning groove are slidably connected.

[0009] Preferably, the lower base of the shock-absorbing component is fixedly installed on the surface of the saddle body, a connecting rod is slidably passed through the inner side of the base, a spring is fixedly installed on the inner side of the base, the top end of the spring is fixedly connected to the bottom end of the connecting rod, and a rubber block is filled inside the spring.

[0010] Preferably, the outer end surface of the limiting block is fixedly installed to one end of the balance cylinder by fixing screws and positioning holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The positioning groove and positioning protrusion improve the installation accuracy of the balance cylinder, thereby improving the performance of the device.

[0013] 2. By adding a damping component to the contact surface between the balance cylinder and the slide saddle, the impact of vibration on the stability of the slide saddle can be reduced. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-3This utility model provides a technical solution: a CNC lathe slide saddle with a built-in balance cylinder, including a slide saddle body 1, a limiting block 2 on the top of the slide saddle body 1, a sliding groove 3 on the surface of the limiting block 2, an installation hole 8 inside the sliding groove 3, a balance cylinder 4 on the outer end of the limiting block 2, a piston rod 5 on the inner side of the sliding groove 3, a positioning hole 7 on the outer end surface of the limiting block 2, a positioning groove 6 on the surface of the slide saddle body 1, a connecting block 9 at the bottom of the balance cylinder 4, a positioning protrusion 10 at the bottom of the connecting block 9, and a shock absorption component 11 on the surface of the slide saddle body 1.

[0020] Specifically, limit blocks 2 are symmetrically fixedly installed on both sides of the top of the slide saddle body 1. An installation hole 8 is opened through the middle of one end of the inner surface of the slide groove 3. A piston rod 5 is slidably inserted through the inner side of the installation hole 8. One end of the piston rod 5 is fixedly connected to the output end of the balance cylinder 4. A positioning groove 6 is opened on the surface of the slide saddle body 1 at one end of the limit block 2. A positioning protrusion 10 is slidably connected to the positioning groove 6. The lower base 13 of the shock absorption component 11 is fixedly installed on the surface of the slide saddle body 1. A connecting rod 16 is slidably inserted through the inner side of the base 13. A spring 14 is fixedly installed on the inner side of the base 13. The top end of the spring 14 is fixedly connected to the bottom end of the connecting rod 16. A rubber block 15 is filled inside the spring 14. The outer end surface of the limit block 2 is fixedly installed to one end of the balance cylinder 4 through a fixing screw 12 and a positioning hole 7.

[0021] In this embodiment, the positioning protrusion 10 connected to the bottom end of the balance cylinder 4 is slid into the interior of the positioning groove 6, so that the piston rod 5 at the end of the balance cylinder 4 passes through the positioning hole 7 into the interior of the slide groove 3. Finally, it is fixed by the fixing screw 12. The extension and retraction of the piston rod 5 can drive the slide rail inside the slide groove 3 to move linearly. By installing the shock absorption component 11 between the balance cylinder 4 and the slide saddle body 1, when the balance cylinder 4 is subjected to vibration force, it will drive the connecting rod 16 to compress the spring 14 inside the base 13. The rubber block 15 can absorb the force generated by the spring 14, reduce the amplitude of the spring 14, and thus improve the stability of the slide saddle.
