Description

Technical Field

[0001] This utility model relates to the field of four-axis machining centers, specifically to a multi-station fixture for a central four-axis machining center. Background Technology

[0002] In the CNC machining industry, especially multi-axis machining centers, tooling fixtures play a crucial role in the forming and precision of parts. A four-axis machining center generally refers to a machining center that uses the fourth axis of a CNC machine tool to process corresponding parts. The multi-station fixtures of a four-axis machining center achieve the simultaneous clamping of multiple workpieces through the structure and assembly method of the fixture itself, and ensure the precision and stability during the machining process.

[0003] Existing four-axis machining centers, when using multi-station fixtures to clamp multiple parts, mostly use multiple cylinders to push the fixtures to clamp the workpieces. However, multiple cylinders not only increase costs but are also more inconvenient to install. Furthermore, the distance between multiple fixtures cannot be adjusted, making them unsuitable for use with machining centers of different sizes and types.

[0004] Therefore, it is necessary to invent a multi-station fixture for a four-axis machining center to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a multi-station fixture for a four-axis machining center. By rotating a screw on one side of the support according to different part sizes, the screw rotation drives the first fixture and the lower first slider to move within a slide rail. When it reaches the appropriate part size position, the cylinder switch on one side of the fixed plate is then turned on, pushing the connecting rod and multiple second inclined blocks on both sides to move. There are connecting grooves between the multiple second inclined blocks and the first inclined block behind the second fixture, allowing the second inclined blocks to compress and push the multiple first inclined blocks and the second fixture for telescopic clamping. This allows for the clamping and fixing of multiple parts, solving the problem mentioned in the background art where existing four-axis machining centers, when using multi-station fixtures to clamp multiple parts, mostly employ multiple cylinders to push the fixture to clamp the workpiece. Multiple cylinders not only increase cost but also make installation inconvenient, and the distance between multiple fixtures cannot be adjusted, making them unsuitable for use with machining centers of different sizes and types.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station fixture for a four-axis machining center, including a mounting plate for mounting the four-axis machining center;

[0007] A fixing plate is installed above the mounting plate and is used to load multi-station fixtures. Mounting holes are opened on the four sides of the mounting plate. Brackets are fixedly connected to the front and rear sides of the fixing plate, and slide rails are fixedly connected to the top of the fixing plate.

[0008] The adjustment mechanisms are all installed on one side of the bracket and are used to adjust the distance;

[0009] The clamping mechanism, mounted above the fixed plate, is used for clamping parts.

[0010] Preferably, the adjusting mechanism includes a screw that passes through the inside of the bracket, one end of the screw is fixedly connected to a first clamp, and a first slider is fixedly connected to the lower part of the first clamp.

[0011] Preferably, the first clamp is V-shaped, and a rubber pad is attached to one side of the first clamp.

[0012] Preferably, the clamping mechanism includes a second clamp, which is movably disposed above the slide rail. A first inclined block is fixedly connected to the rear of the second clamp. A cylinder is fixedly disposed on one side above the fixed plate. A connecting rod is fixedly connected to the output end of the cylinder. Second inclined blocks are fixedly connected to both sides of the connecting rod.

[0013] Preferably, a second slider is fixedly connected to the lower part of the second clamp, and anti-slip protrusions are fixedly connected to one side of the second clamp.

[0014] Preferably, a docking groove is provided between the first inclined block and the second inclined block, and the first inclined block and the second inclined block are in a limiting sliding connection.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] This invention, through the setting of adjustment and clamping mechanisms, not only requires only one cylinder to drive multiple workstations for clamping, but also allows for adjustment according to the size and type of different parts. First, by rotating the screw on one side of the bracket according to the different sizes of the parts, the rotation of the screw drives the first clamp and the first slider below to move within the slide rail. When it moves to the appropriate size position of the part, the cylinder switch on one side of the fixed plate is then turned on, pushing the connecting rod and multiple second inclined blocks on both sides to move. There are docking grooves between the multiple second inclined blocks and the first inclined block behind the second clamp, so that the second inclined blocks squeeze and push the multiple first inclined blocks and the second clamp to extend and retract for clamping, thus clamping and fixing multiple parts.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The multi-station fixture of a central four-axis machining center shown includes a mounting plate 1 for mounting the four-axis machining center;

[0027] The fixing plate 3 is installed above the mounting plate 1 and is used to load multi-station fixtures. Mounting holes 2 are opened on the four sides of the mounting plate 1. Brackets 4 are fixedly connected to the front and rear sides of the fixing plate 3. Slide rails 5 are fixedly connected to the top of the fixing plate 3.

[0028] The adjustment mechanisms 6 are all installed on one side of the bracket 4 and are used to adjust the distance;

[0029] The clamping mechanism 7, installed above the fixed plate 3, is used for clamping parts. By rotating the screw 601 on one side of the bracket 4 according to different part sizes, the screw 601 rotates and drives the first clamp 602 and the first slider 604 below to move within the slide rail 5. When it moves to the appropriate size position of the part, the cylinder 705 switch on one side of the fixed plate 3 is turned on, pushing the connecting rod 706 and multiple second inclined blocks 707 on both sides to move. There is a docking groove between the multiple second inclined blocks 707 and the first inclined block 704 behind the second clamp 701, so that the second inclined blocks 707 squeeze and push the multiple first inclined blocks 704 and the second clamp 701 to extend and clamp, thus clamping and fixing multiple parts.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the adjustment mechanism 6 includes a screw 601 that passes through the inside of the bracket 4. One end of the screw 601 is fixedly connected to a first clamp 602, and a first slider 604 is fixedly connected to the bottom of the first clamp 602. By rotating the multiple screws 601 on one side of the bracket 4, the first clamp 602 can be driven to extend and retract within the slide rail 5, thereby adjusting and clamping parts of different sizes.

[0031] like Figure 3 As shown, the first clamp 602 is V-shaped, and a rubber pad 603 is attached to one side of the first clamp 602. The V-shape of the first clamp 602 can enhance the clamping firmness, and the rubber pad 603 attached to the surface can prevent excessive clamping force from causing scratches on the surface of the parts.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the clamping mechanism 7 includes a second clamp 701, which is movably mounted above the slide rail 5. A first inclined block 704 is fixedly connected to the rear of the second clamp 701. A cylinder 705 is fixedly mounted on one side of the upper part of the fixing plate 3. A connecting rod 706 is fixedly connected to the output end of the cylinder 705. Second inclined blocks 707 are fixedly connected to both sides of the connecting rod 706. By opening the switch of the cylinder 705 on one side of the fixing plate 3, the connecting rod 706 and the multiple second inclined blocks 707 on both sides are pushed to move. There is a docking groove between the multiple second inclined blocks 707 and the first inclined block 704 behind the second clamp 701, so that the second inclined blocks 707 squeeze and push the multiple first inclined blocks 704 and the second clamp 701 to perform telescopic clamping.

[0033] like Figure 3 and Figure 4As shown, a second slider 702 is fixedly connected to the lower part of the second clamp 701, and anti-slip protrusions 703 are fixedly connected to one side of the second clamp 701. Multiple anti-slip protrusions 703 are provided on the surface of the second clamp 701, which increases the friction between the clamp and the parts, thereby playing an anti-slip role. During the movement, the second clamp 701 moves within the slide rail 5 through the lower second slider 702, which improves the stability during movement.

[0034] like Figure 2 , Figure 4 and Figure 5 As shown, a docking groove is provided between the first inclined block 704 and the second inclined block 707. The first inclined block 704 and the second inclined block 707 are slidably connected. Through the docking groove between the first inclined block 704 and the second inclined block 707, when the cylinder 705 pushes the connecting rod 706 and the external second inclined block 707 to extend and retract, it can push the first inclined block 704 and the second clamp 701 to squeeze and move to both sides. When the cylinder 705 pulls the connecting rod 706 and the second inclined block 707, it can also pull the first inclined block 704 and the second clamp 701 to move inward, thereby realizing clamping and releasing.

[0035] The working principle of this practical system is as follows: First, the mounting plate 1 is installed on the four-axis machining center equipment via a threaded connection. Then, the external power supply is turned on. Next, according to the size of each part, multiple screws 601 on one side of the bracket 4 are rotated, causing the first clamp 602 to move telescopically within the slide rail 5, thereby adjusting the distance between the first clamp 602 and the second clamp 701. After the appropriate distance is adjusted, multiple parts are placed sequentially into the first clamp 602 and the second clamp 701. Once all the parts are in place, the cylinder 705 switch on one side of the fixing plate 3 is turned on, pushing the connecting rod 706 and multiple second inclined blocks 707 on both sides to extend. The retraction movement is achieved because there are connecting grooves between the multiple second inclined blocks 707 and the first inclined block 704 behind the second clamp 701. This causes the connecting rod 706 and the multiple second inclined blocks 707 to squeeze and push the multiple first inclined blocks 704 and the second clamp 701 to extend and retract towards the part, thus completing the clamping of the part. At the same time, the second clamp 701 uses anti-slip protrusions 703 on its surface to prevent slippage during the clamping process, thus preventing the part from shaking during processing. After that, the four-axis machining center can be started to process multiple parts. In this way, the use of the multi-station fixture of the four-axis machining center is completed.

[0036] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
