Description

Technical Field

[0001] This utility model belongs to the field of machining center technology, specifically relating to a protective structure for the back of a machining center worktable. Background Technology

[0002] The machining center worktable is one of the core components of CNC machining equipment. It is primarily used to fix and position the workpiece and achieve precise movement during machining through multi-axis linkage, ensuring that the cutting tool efficiently completes cutting, drilling, milling, and other processes from different angles. Common types include rotary worktables (capable of multi-faceted machining, improving the efficiency of handling complex parts), indexing worktables (precise angular indexing, suitable for gear or symmetrical part machining), and dual-station worktables (supporting simultaneous loading / unloading and machining, reducing downtime). Worktables are typically made of high-strength cast iron or alloy steel, combining rigidity and shock resistance. Combined with high-precision drive systems such as servo motors, ball screws, and linear guides, they ensure micron-level positioning accuracy and repeatability. Their design emphasizes load-bearing capacity and thermal deformation control to withstand heavy cutting or long-term operation. These worktables are widely used in aerospace (precision structural parts), automotive manufacturing (engine components), mold processing (complex curved surfaces), and other fields, serving as a key foundational platform for improving automated production efficiency and machining accuracy.

[0003] During machining, high-speed splashing of metal chips, cutting fluid, or oil mist is generated. The back protection structure can effectively prevent these fragments and liquids from spreading outward, avoiding scratches, burns, or chemical injuries to operators. However, conventional protection structures cannot withstand external collisions. The impact of a collision may cause the protection structure to shatter, and the flying fragments may cause secondary injuries. Therefore, we propose a back protection structure for the machining center worktable. Utility Model Content

[0004] This utility model aims to address the shortcomings of the prior art by providing a protective structure for the back of a machining center worktable, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A back protection structure for a machining center workbench includes: a mounting base, a machining center body fixedly connected to one side of the mounting base, a cutting blade fixedly connected to one side of the machining center body, a back protection component fixedly connected to the top side of the mounting base, and a movable base provided on the top of the mounting base, the position of the back protection component matching the movable base.

[0007] Preferably, the back protection assembly includes a protective retractable base, a limiting base plate, a retractable protective shell, reinforcing nails, reinforcing mounting nails, a honeycomb reinforcement structure, a connecting baffle, and reinforcing columns. The protective retractable base is fixedly connected to the top of the mounting base, and multiple limiting base plates are fixedly connected to the top two sides of the protective retractable base.

[0008] Preferably, a plurality of the shrink protective shells are disposed inside the protective shrink base, and the reinforcing nails are fixedly connected to the top of one of the shrink protective shells.

[0009] Preferably, a plurality of the reinforcing mounting nails are disposed at the bottom of the protective shrinkable base, the honeycomb reinforcing structure is disposed on both sides of the inner wall of the protective shrinkable base, the connecting baffle is fixedly connected to one side of the honeycomb reinforcing structure, the reinforcing column is fixedly connected to the inner wall of the honeycomb reinforcing structure, and the curvature of one end of the connecting baffle matches that of the shrinkable protective shell.

[0010] Preferably, the movable component includes a movable groove, a return spring, a limiting slide rail, and a movable slider. The multiple movable grooves are all formed on both sides of the inner bottom of the protective retractable base, and the return spring is fixedly connected to the inner wall of the movable groove.

[0011] Preferably, the limiting slide rails are all sleeved on the inner wall of the return spring, the movable slider is fixedly connected to one end of the return spring, the movable slider is slidably connected to the surface of the limiting slide rails, and the movable sliders are all fixedly connected to the bottom of the honeycomb reinforced structure.

[0012] Preferably, the top of the mounting base is provided with a processing table.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The back protection component can effectively block the outward spread of fragments and liquids through its own structure, avoiding scratches, burns or chemical injuries to operators, thereby further improving the functionality of the device. At the same time, it can be linked with the moving components to move the protective structure in time for protection while completing the retraction activity, further improving the functionality and safety of the device.

[0015] 2. The back protection assembly helps protect the internal structure of the device. Basic back protection is achieved through the interlocking of the protective retractable base and the retractable protective shell. The limiting base plate effectively protects and limits the protective retractable base from the top. Reinforcing nails reinforce the top of the retractable protective shell using their own structure. Reinforcing mounting nails reinforce the protective retractable base from the back. The honeycomb reinforcement structure uses its own honeycomb structure to withstand impacts, collapsing upon impact to prevent secondary injuries from flying fragments. Simultaneously, the connecting baffle, with its curvature, helps the retractable protective shell not obstruct movement during retraction or movement, further improving the device's functionality. Furthermore, the interlocking with the moving components allows the honeycomb reinforcement structure and connecting baffle to be reset, enhancing the device's functionality. Reinforcing columns further reinforce the honeycomb reinforcement structure from the inside. Attached Figure Description

[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. Example

[0026] Please see Figure 1-6 The technical solution provided in this embodiment is as follows:

[0027] A back protection structure for a machining center worktable includes: a mounting base 4, a machining center body 1 fixedly connected to one side of the mounting base 4, a cutting blade 2 fixedly connected to one side of the machining center body 1, a back protection component 5 fixedly connected to one side of the top of the mounting base 4, a movable base 7 provided on the top of the mounting base 4, the position of the back protection component 5 matching that of the movable base 7, and a machining table 3 provided on the top of the mounting base 4.

[0028] In this embodiment, the machining center body 1 and the cutting blade 2 are processed on the surface of the machining table 3. The generated debris is effectively protected by the back protection component 5 on the top of the mounting base 4. At the same time, the back protection component 5 and the movable component 6 are linked together to maintain the basic function of protection while effectively resisting impact and preventing secondary damage, thereby further improving the safety and functionality of the device. The movable base 7 can effectively ensure the mobility of the machining table 3.

[0029] The back protection assembly 5 includes a protective retractable base 501, a limiting base plate 502, a retractable protective shell 503, a reinforcing nail 504, a reinforcing mounting nail 505, a honeycomb reinforcing structure 506, a connecting baffle 507, and a reinforcing column 508. The protective retractable base 501 is fixedly connected to the top of the mounting base 4, and multiple limiting base plates 502 are fixedly connected to the top two sides of the protective retractable base 501.

[0030] In this embodiment, the back protection component 5 provides a basic space for the shrinkable protective shell 503 to shrink and protect through the protective shrinkable base 501, and the limiting base plate 502 can protect the protective shrinkable base 501 from the top and limit the movement of the shrinkable protective shell 503.

[0031] Multiple shrinkable protective shells 503 are disposed inside the protective shrinkable base 501, and reinforcing nails 504 are fixedly connected to the top of one of the shrinkable protective shells 503.

[0032] In this embodiment, the shrinkable protective shell 503 can move inside the protective shrinkable base 501 to increase the protection range of the back protection component 5, while the reinforcing nail 504 can further reinforce the shrinkable protective shell 503 from one end.

[0033] Multiple reinforcing mounting nails 505 are disposed at the bottom of the protective shrink base 501, honeycomb reinforcing structures 506 are disposed on both sides of the inner wall of the protective shrink base 501, connecting baffles 507 are fixedly connected to one side of the honeycomb reinforcing structure 506, and reinforcing columns 508 are fixedly connected to the inner wall of the honeycomb reinforcing structure 506. The curvature of one end of the connecting baffles 507 matches that of the shrink protective shell 503.

[0034] In this embodiment, the reinforcing mounting nail 505 can help further reinforce the protective shrink base 501 from the bottom. At the same time, the honeycomb reinforcement structure 506 can absorb the side impact together with the connecting baffle 507 using its own honeycomb structure. At the same time, the honeycomb structure itself can collapse when the impact causes deformation, so that there will be no debris flying and causing secondary damage to the device as a whole, thereby further improving the functionality and safety of the device. The reinforcing column 508 can further reinforce the interior of the honeycomb reinforcement structure 506.

[0035] The movable component 6 includes a movable groove 601, a return spring 602, a limit slide rail 603, and a movable slider 604. Multiple movable grooves 601 are formed on both sides of the bottom inside the protective retractable base 501, and the return spring 602 is fixedly connected to the inner wall of the movable groove 601.

[0036] In this embodiment, the movable component 6 can utilize the movable groove 601 to provide space for the overall movement of the movable component 6, while the return spring 602 can use its own structure to drive the movable slider 604 to reset when there is no resistance, thereby further improving the flexibility of the back protection component 5.

[0037] The limiting slide rails 603 are all sleeved on the inner wall of the return spring 602. The movable slider 604 is fixedly connected to one end of the return spring 602. The movable slider 604 is slidably connected to the surface of the limiting slide rail 603. The movable slider 604 is fixedly connected to the bottom of the honeycomb reinforced structure 506.

[0038] In this embodiment, the limiting slide rail 603 can provide limiting guidance for the movement of the movable slider 604. The movable slider 604 itself is fixed to the bottom of the honeycomb reinforcement structure 506. When the honeycomb reinforcement structure 506 moves back and forth to retract and expand the shrinkable protective shell 503 due to the curvature of the connecting baffle 507, it will also drive the movable slider 604 to move, thereby providing a basis for the movement of the honeycomb reinforcement structure 506. At the same time, when the shrinkable protective shell 503 expands and a gap is generated, the return spring 602 is used to drive the honeycomb reinforcement structure 506 to reset, thereby further improving the functionality and safety of the device.

[0039] Working principle: This equipment uses the machining center body 1 and cutting blades 2 to process parts on the machining table 3, thereby completing basic machining work. The mounting base 4 and movable base 7 help maintain the stability of the machining center body 1 while providing a base for movement. The back protection component 5 can effectively block the outward spread of fragments and liquids using its own structure, avoiding scratches, burns or chemical injuries to the operator. In the event of an accidental collision, it will also protect the device body, preventing secondary injuries caused by flying fragments, thereby further improving the functionality of the device. At the same time, it is linked with the movable component 6, and can move the protective structure in time to provide protection while completing the retraction movement, further improving the functionality and safety of the device.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
