Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic chuck technology, and in particular to a hydraulic chuck support structure. Background Technology
[0002] In the machinery manufacturing industry, hydraulic chucks are the main clamping tools for CNC lathes to hold and rotate workpieces. Hydraulic chucks achieve effective internal support through hydraulic pressure, improving machining stability and are suitable for precision machining.
[0003] Hydraulic chuck support structures typically use a simple bolt connection to fix the chuck to the machine tool's worktable or a specific support base. Corresponding bolt holes are pre-machined on the chuck and the support base, and the two are fastened together by bolts.
[0004] However, this method lacks precision and flexibility in installation and positioning. When adjusting the chuck position for different processing tasks, the operation is cumbersome, time-consuming, and labor-intensive, failing to quickly adapt to diverse processing needs. This results in excessively long preparation times, significantly reducing production efficiency. Furthermore, the lack of effective anti-loosening measures means that during processing, especially under heavy cutting or complex conditions, the chuck jaws are prone to loosening due to machine tool vibration, large cutting force impacts, and other external forces. Loose jaws not only cause unstable workpiece clamping, leading to dimensional deviations and reduced surface quality, but can also potentially cause safety accidents, severely impacting processing stability and accuracy. During prolonged operation, hydraulic chucks generate significant heat due to friction with the workpiece and energy loss within the hydraulic system. If this heat cannot be dissipated promptly, the hydraulic oil temperature will continue to rise, reducing its viscosity and deteriorating its lubrication performance. This, in turn, affects the normal operation of the hydraulic system and may even damage the chuck due to thermal expansion and deformation, shortening equipment lifespan, increasing maintenance costs and downtime, and hindering production continuity and efficiency.
[0005] Therefore, a hydraulic chuck support structure is provided to solve the problems mentioned in the background art. Utility Model Content
[0006] To overcome the above shortcomings, this utility model provides a hydraulic chuck support structure, aiming to improve the existing technology's lack of precise and flexible installation and positioning. When adjusting the chuck position for different processing tasks, the operation is cumbersome, time-consuming, and labor-intensive, unable to quickly adapt to diverse processing needs, resulting in excessively long processing preparation time and significantly reduced production efficiency. During processing, especially when performing heavy cutting or facing complex working conditions, the chuck jaws are prone to loosening due to external forces such as machine tool vibration and large cutting force impacts. Loose chuck jaws not only cause unstable workpiece clamping, resulting in dimensional deviations and decreased surface quality, but also generate a large amount of heat during prolonged operation due to friction between the hydraulic chuck and the workpiece, as well as energy loss within the hydraulic system itself. If the heat cannot be dissipated in time, the hydraulic oil temperature will continue to rise, causing its viscosity to decrease and its lubrication performance to deteriorate, thus affecting the normal operation of the hydraulic system.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic chuck support structure, including a base, an electric slide rail mounted on the base, an electric slider slidably connected to the electric slide rail, a support seat fixedly connected to the upper side of the electric slider, a hydraulic chuck inside the support seat, an installation assembly provided on the rear side of the hydraulic chuck, a cooling assembly provided on the outer side of the hydraulic chuck, jaws installed inside the hydraulic chuck, and anti-loosening components provided on the outer side of the jaws; the installation assembly includes a mounting base rotatably connected to the rear side of the hydraulic chuck, a dovetail block fixedly connected to the outer side of the mounting base, a dovetail groove opened inside the support seat, and installation bolts provided inside the support seat.
[0008] Furthermore, the cooling assembly includes a cooling jacket, which is fixedly installed on the outside of the hydraulic chuck. An inlet pipe is fixedly connected to the cooling jacket, and a filter screen is fixedly installed inside the inlet pipe. A cooling pipe is opened inside the cooling jacket.
[0009] Furthermore, the anti-loosening component includes an upper anti-loosening member disposed on the outside of the chuck, and a lower anti-loosening member disposed on the lower side of the upper anti-loosening member. Fixing bolts are disposed inside the upper and lower anti-loosening members, and nuts are disposed on the fixing bolts.
[0010] Furthermore, the dovetail block is slidably connected inside the dovetail groove.
[0011] Furthermore, the nut is threaded onto the fixing bolt.
[0012] Furthermore, the mounting bolt is threaded into the inside of the dovetail block.
[0013] Furthermore, the hydraulic chuck is slidably connected to the base.
[0014] Furthermore, the clamping claw is provided with three parts, and the upper anti-loosening member and the lower anti-loosening member are attached to the outer side of the clamping claw.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, when installing the hydraulic chuck, first connect the mounting base to the hydraulic chuck and align the dovetail block with the dovetail groove of the support base. Then, use mounting bolts to tighten the dovetail block and the support base to achieve stable installation. At the same time, the electric slide rail and electric slider of the base can accurately adjust the horizontal position of the support base and the hydraulic chuck. During operation, the three jaws in the hydraulic chuck are driven by the hydraulic system to clamp and release the workpiece. Since the external force during processing can easily cause the jaws to loosen, the upper anti-loosening part and the lower anti-loosening part are attached to the outside of the jaws and tightened by fixing bolts and nuts to form a clamping force, which effectively suppresses the loosening of the jaws and ensures the processing accuracy.
[0017] 2. In this utility model, when the hydraulic chuck is working, heat is generated due to friction with the workpiece and energy loss of the hydraulic system itself. At this time, the cooling component plays a role. The coolant flows into the cooling jacket from the inlet pipe. The filter screen in the inlet pipe can filter impurities to prevent blockage of the cooling pipe. The coolant circulates in the cooling pipe of the cooling jacket, absorbing the heat of the hydraulic chuck and keeping its temperature within a suitable range. This avoids changes in the performance of the hydraulic oil and deformation of the chuck caused by high temperature, ensuring the stability and accuracy of processing and helping to extend the service life of the hydraulic chuck.

[0025] 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.
[0026] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a hydraulic chuck support structure, including a base 1, an electric slide rail 9 mounted on the base 1, an electric slider 6 slidably connected to the electric slide rail 9, a support seat 2 fixedly connected to the upper side of the electric slider 6, a hydraulic chuck 3 inside the support seat 2, an installation component 4 provided on the rear side of the hydraulic chuck 3, a cooling component 5 provided on the outer side of the hydraulic chuck 3, a chuck claw 7 installed inside the hydraulic chuck 3, and an anti-loosening component 8 provided on the outer side of the chuck claw 7; the installation component 4 includes a mounting base 44, which is rotatably connected to the rear side of the hydraulic chuck 3, and a dovetail block 41 fixedly connected to the outer side of the mounting base 44; a dovetail groove 42 is opened inside the support seat 2, and an installation bolt 43 is provided inside the support seat 2; the dovetail block 41 is slidably connected to the inside of the dovetail groove 42, and the installation bolt 43 is threadedly connected to the inside of the dovetail block 41; the hydraulic chuck 3 is slidably connected to the base 1; and three chuck claws 7 are provided, with an upper anti-loosening component 81 and a lower anti-loosening component 82 fitting against the outer side of the chuck claw 7;
[0027] When installing the hydraulic chuck, align the dovetail block 41 on the outside of the mounting base 44 with the dovetail groove 42 inside the support base 2. Then, slide the dovetail block 41 along the dovetail groove 42 to achieve the initial positioning of the hydraulic chuck 3 in the support base 2. Subsequently, the mounting bolt 43 is threaded into the dovetail block 41 to fasten the dovetail block 41 to the support base 2, thus achieving stable installation of the hydraulic chuck 3 on the support base 2. During this process, the dovetail groove 42 and the dovetail block 41 cooperate to provide precise positioning guidance, ensuring accurate installation position and firm connection, and being able to withstand processing force. Since there is an electric slide rail 9 on the base 1, and the electric slider 6 of the electric slide rail 9 is fixedly connected to the support base 2, by controlling the electric slide rail 9, the horizontal position of the support base 2 and the hydraulic chuck 3 on the base 1 can be precisely adjusted to meet the needs of different processing positions and achieve flexible positioning.
[0028] Reference Figure 1 , Figure 3 and Figure 4 The cooling assembly 5 includes a cooling jacket 51, which is fixedly installed on the outside of the hydraulic chuck 3. An inlet pipe 54 is fixedly connected to the cooling jacket 51, and a filter screen 53 is fixedly installed inside the inlet pipe 54. A cooling pipe 52 is opened inside the cooling jacket 51.
[0029] When the hydraulic chuck 3 is working, heat is generated due to friction with the workpiece and energy loss of the hydraulic system. In order to ensure its normal performance and extend its service life, the cooling component 5 plays a role. The coolant enters the cooling jacket 51 from the inlet pipe 54. The filter screen 53 in the inlet pipe 54 filters the impurities in the coolant to prevent them from entering the cooling pipe 52 and causing blockage. The coolant circulates in the cooling pipe 52 inside the cooling jacket 51, absorbing the heat generated by the hydraulic chuck 3, reducing its temperature and maintaining it within a suitable working temperature range. This avoids problems such as changes in hydraulic oil performance and chuck deformation caused by excessive temperature, thus ensuring machining stability and accuracy.
[0030] Reference Figure 1 , Figure 2 and Figure 5 The anti-loosening component 8 includes an upper anti-loosening component 81, which is disposed on the outside of the claw 7. A lower anti-loosening component 82 is disposed on the lower side of the upper anti-loosening component 81. A fixing bolt 83 is disposed inside the upper anti-loosening component 81 and the lower anti-loosening component 82. A nut 84 is disposed on the fixing bolt 83, and the nut 84 is threadedly connected to the fixing bolt 83.
[0031] The three jaws 7 inside the hydraulic chuck 3 are driven by the hydraulic system to clamp and release the workpiece during operation. Because external forces such as machine tool vibration and cutting force impact during processing can easily cause the jaws 7 to loosen, affecting the processing accuracy, an anti-loosening component 8 is set. The upper anti-loosening component 81 and the lower anti-loosening component 82 are respectively attached to the outer side of the jaws 7. The fixing bolt 83 passes through the upper anti-loosening component 81 and the lower anti-loosening component 82. The nut 84 is threadedly connected to the fixing bolt 83 for tightening, forming a clamping force on the jaws 7, effectively suppressing the loosening of the jaws 7, ensuring that the workpiece is always stably clamped during processing, and ensuring processing accuracy.
[0032] Working principle: When using this device, first rotate the mounting base 44 to the rear of the hydraulic chuck 3, aligning the dovetail block 41 on the outside of the mounting base 44 with the dovetail groove 42 inside the support base 2. Then, use the mounting bolt 43 to thread it into the dovetail block 41, securing the dovetail block 41 to the support base 2 for stable installation. Simultaneously, because the base 1 has an electric slide rail 9, its electric slider 6 is fixedly connected to the support base 2. By controlling the electric slide rail 9, the horizontal position of the support base 2 and the hydraulic chuck 3 on the base 1 can be precisely adjusted. The three jaws 7 inside the hydraulic chuck 3 are driven by the hydraulic system during operation, achieving clamping and releasing operations on the workpiece. Due to machine tool vibration, cutting force impact, and other external forces during processing, the jaws are prone to... 7. Loosening affects machining accuracy. The upper anti-loosening part 81 and the lower anti-loosening part 82 are respectively attached to the outer side of the jaw 7. The fixing bolt 83 passes through the upper anti-loosening part 81 and the lower anti-loosening part 82. The nut 84 is threaded onto the fixing bolt 83 for tightening, forming a clamping force on the jaw 7, which effectively inhibits the loosening of the jaw 7. The hydraulic chuck 3 generates heat due to friction with the workpiece and energy loss of the hydraulic system. Coolant enters the cooling jacket 51 from the inlet pipe 54. The filter screen 53 in the inlet pipe 54 filters impurities in the coolant to prevent it from entering the cooling pipe 52 and causing blockage. The coolant circulates in the cooling pipe 52 inside the cooling jacket 51, absorbing the heat generated by the hydraulic chuck 3, reducing its temperature and maintaining it within a suitable working temperature range.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
