Description

Technical Field

[0001] This utility model relates to the field of CNC composite machine technology, specifically a quick-locking worktable for CNC composite machines. Background Technology

[0002] A composite machine tool, also known as a composite machining center, is a processing device based on CNC machine tools, integrating multiple processes such as turning, milling, drilling, and grinding into one unit. This equipment improves machining accuracy and efficiency by reducing the number of repeated workpiece clamping operations, and is mainly used in the machining of complex parts in the aerospace, automotive, and mold industries. As a high-precision machining device, CNC composite machines have been widely used in mechanical manufacturing and other fields. The worktable is the core component of a CNC composite machine used to place the workpiece; its stability and positioning accuracy directly affect the machining process.

[0003] Currently, most CNC composite machine worktables on the market use traditional methods such as bolt fastening to lock and fix the fixture plate. However, the locking and unlocking process requires the use of special tools to tighten the bolts one by one, which is cumbersome and time-consuming, seriously affecting the processing efficiency. This inefficiency is even more prominent in production scenarios where different specifications of workpieces need to be changed frequently.

[0004] Therefore, we propose a quick-locking worktable for CNC composite machines to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a quick-locking worktable for CNC composite machines. This solves the problem mentioned in the background art, where CNC composite machine worktables mostly use traditional methods such as bolt fastening to lock and fix the fixture plate. The locking and disassembly process requires the use of special tools to tighten each bolt individually, which is cumbersome, time-consuming, and seriously affects processing efficiency. This inefficiency is even more prominent in production scenarios where different specifications of workpieces need to be frequently changed.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0009] A quick-locking worktable for a CNC composite machine includes a CNC composite machine body, a lifting platform disposed on the upper surface of the CNC composite machine body, and a work base connected to the upper surface of the lifting platform, and further includes:

[0010] The worktable is located on the upper surface of the work base, and the work base contains a drive assembly for adjusting the position of the worktable.

[0011] A fixture plate is set on the upper surface of the workbench plate, and a limiting mechanism is connected to the lower surface of the fixture plate to limit the position of the fixture plate.

[0012] The locking slide bar slides laterally and engages with the inside of the worktable. The worktable has a locking mechanism inside, which drives the locking slide bar to quickly lock the fixture plate.

[0013] Furthermore, the limiting mechanism includes a positioning slide and a locking slide. The positioning slide is evenly opened on the upper surface of the worktable, and the cross-section of the positioning slide is a "T" shaped structure. The locking slide is fixed to the lower surface of the clamp plate, and the locking slide is slidably embedded into the inner side of the positioning slide.

[0014] Furthermore, the locking mechanism includes a positioning groove, a return spring, and a horizontal plate. The positioning groove is laterally opened on the inner side of the worktable, and the locking slide rod is slidably engaged on the inner side of the positioning groove. The return spring is sleeved on the outer surface of the locking slide rod and is located inside the positioning groove. The horizontal plate is fixed on the outer surface of the locking slide rod, and one side of the horizontal plate is in contact with the side edge of the worktable.

[0015] Furthermore, the locking mechanism also includes a locking groove and a locking clip. The locking groove is laterally opened on the lower end face of the locking slide plate, and the locking clip is evenly fixed on the outer surface of the locking slide rod. The cross-section of the locking clip is "L" shaped, and the locking clip is slidably embedded in the locking groove.

[0016] Furthermore, a locking sleeve is fitted onto one end of the outer surface of the locking slide rod, and a connecting thread is uniformly provided on one end of the outer surface of the locking sleeve. The locking sleeve is embedded in the worktable and connected to the inner wall of the worktable through the connecting thread.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a quick-locking worktable for CNC composite machines, which has the following advantages:

[0019] This invention utilizes a locking mechanism to drive a locking slide rod, which in turn causes the locking clip to engage or disengage from the locking groove. Combined with the initial positioning by a limiting mechanism, the locking and disassembly of the fixture plate can be completed without the need for special tools, significantly reducing operation time and improving processing efficiency. It is particularly suitable for production scenarios involving frequent workpiece changes. The fixing mechanism employs a "T"-shaped positioning groove that works in conjunction with the locking slide plate, effectively limiting the vertical and horizontal movement of the fixture plate. The locking mechanism uses an "L"-shaped locking clip that works in conjunction with the locking groove, enhancing the locking's firmness. Simultaneously, the locking sleeve provides positioning support for the locking slide rod, preventing displacement during locking and ensuring locking stability and positioning accuracy, thereby improving the workpiece's processing quality.

[0026] 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.

[0027] Example

[0028] like Figure 1-5 As shown, an embodiment of this utility model discloses a quick-locking worktable for a CNC composite machine, including a CNC composite machine body 1, a lifting platform 2 disposed on the upper surface of the CNC composite machine body 1, and a working base 3 connected to the upper surface of the lifting platform 2, and further including:

[0029] The CNC composite machine body 1 serves as the installation base for the entire worktable. The lifting platform 2 is fixed to the upper surface of the CNC composite machine body 1 by bolts. The working base 3 is welded to the upper surface of the lifting platform 2. The lifting platform 2 adopts the existing lifting structure, and the height of the working base 3 can be adjusted according to processing requirements.

[0030] The worktable 5 is set on the upper surface of the work base 3. The work base 3 is equipped with a drive assembly 4 for adjusting the position of the worktable 5. The drive assembly 4 adopts the existing transmission structure of servo motor driving ball screw. The nut seat of the ball screw is connected to the lower surface of the worktable 5 by bolts. After the servo motor is started, it drives the ball screw to rotate, thereby driving the worktable 5 to move precisely in the horizontal direction on the work base 3.

[0031] A clamping plate 7 is disposed on the upper end face of the workbench plate 5. A limiting mechanism is connected to the lower end face of the clamping plate 7 to limit the position of the clamping plate 7. The limiting mechanism includes a positioning slide 6 and a locking slide plate 8. The positioning slide 6 is evenly distributed on the upper end face of the workbench plate 5, and the cross-section of the positioning slide 6 is a "T" shaped structure. The locking slide plate 8 is fixed to the lower end face of the clamping plate 7 and slides into the inner side of the positioning slide 6. The "T" shaped positioning slide 6 and the locking slide plate 8 cooperate to effectively prevent the clamping plate 7 from shifting in the vertical direction, and at the same time limit the horizontal movement direction of the clamping plate 7 to ensure the positioning accuracy of the clamping plate 7 during installation.

[0032] The locking slide rod 11 is laterally slidably engaged with the inner side of the worktable plate 5. The worktable plate 5 has a locking mechanism inside, used to drive the locking slide rod 11 to quickly lock the clamp plate 7. The locking mechanism is connected to the locking slide rod 11 via a transmission, used to drive the locking slide rod 11 to move quickly, achieving rapid locking and unlocking of the clamp plate 7. The locking mechanism includes a positioning groove 10, a return spring 12, and a horizontal plate 13. The positioning groove 10 is laterally opened on the inner side of the worktable plate 5, and the locking slide rod 11 is slidably engaged with the inner side of the positioning groove 10. The return spring 12 is sleeved on the... The outer surface of the locking slide rod 11 is fixed, and the return spring 12 is located inside the positioning groove 10. The return spring 12 can reset the locking slide rod 11, so that the locking slide plate 8 can be locked in the future by the locking clip 16. The horizontal plate 13 is fixed on the outer surface of the locking slide rod 11, and one side of the horizontal plate 13 is in contact with the side of the worktable plate 5. By pushing or pulling the horizontal plate 13, the locking slide rod 11 can be driven to slide in the positioning groove 10. The return spring 12 deforms during the sliding of the locking slide rod 11 and generates a reset force, which facilitates the reset of the locking slide rod 11.

[0033] The locking mechanism also includes a locking groove 9 and a locking clip 16. The locking groove 9 is laterally formed on the lower end face of the locking slide plate 8. The locking clip 16 is evenly fixed on the outer surface of the locking slide rod 11. The cross-section of the locking clip 16 is "L"-shaped, and the locking clip 16 slides into the locking groove 9. The locking clip 16 and the locking groove 9 are positioned correspondingly. When the locking slide rod 11 slides, the locking clip 16 can slide into the locking groove 9. When the locking slide rod 11 slides under the drive of the locking mechanism, the locking clip 16 moves together with the locking slide rod 11, engaging or disengaging from the locking groove 9, thereby locking or unlocking the clamp plate 7. The "L"-shaped locking clip 16 enhances the stability of the engagement with the locking groove 9. To improve the locking effect, a locking sleeve 14 is fitted onto one end of the outer surface of the locking slide rod 11. The outer surface of the locking sleeve 14 is uniformly provided with connecting threads 15, and the locking sleeve 14 is embedded in the worktable plate 5 and connected to the inner wall of the worktable plate 5 through the connecting threads 15. The locking sleeve 14 provides positioning and support for one end of the locking slide rod 11, while the inner side of the locking sleeve 14 can contact the horizontal plate 13, limiting the position of the horizontal plate 13 and preventing it from shifting or wobbling after locking, thus ensuring the stability of the locking slide rod 11. The connecting threads 15 achieve a firm connection with the worktable plate 5, preventing the locking slide rod 11 from shifting during sliding and ensuring the working stability of the locking mechanism.

[0034] When using the fixture plate 7, first pull the locking slide bar 11 outward, which will allow the locking slide bar 11 to slide outward in the positioning groove 10. The return spring 12 will be compressed. At this time, the locking clip 16 will move outward together with the locking slide bar 11, away from the position of the positioning groove 6.

[0035] Next, align the locking slide plate 8 at the lower end of the clamp plate 7 with the positioning groove 6 on the worktable plate 5, and slide the locking slide plate 8 into the positioning groove 6 to complete the initial positioning of the clamp plate 7; loosen the horizontal plate 13, and the return spring 12 pushes the horizontal plate 13 back to its original position under the action of elastic force. The horizontal plate 13 drives the locking slide rod 11 to slide inward, so that the locking clip 16 is embedded in the locking groove 9 on the locking slide plate 8, thereby realizing the quick locking of the clamp plate 7; then, by turning the locking sleeve 14, the inner wall of the locking sleeve 14 can be made to contact the horizontal plate 13, which can lock and limit the position of the horizontal plate 13, thereby ensuring the stability of the locking slide rod 11; a firm connection with the worktable plate 5 is achieved through the connecting thread 15 to prevent the locking slide rod 11 from shifting during the sliding process and to ensure the working stability of the locking mechanism;

[0036] When it is necessary to disassemble the clamp plate 7, simply loosen the locking sleeve 14, and then pull the locking slide bar 11 outward to disengage the locking clip 16 from the locking groove 9. Then, the clamp plate 7 can be pulled out along the positioning slide groove 6. The operation is convenient and efficient.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
