Technical Field

[0001] This utility model relates to the field of non-standard fixture technology, and in particular to a special fixture for long shaft parts. Background Technology

[0002] Generally, the machining of long shaft parts is a non-standard part machining process. It usually requires the use of clamping fixtures to hold the long shaft parts and assemble them into interchangeable quick base plates, four-axis bridge plates, five-axis worktables, etc., and use them in conjunction with multi-axis machining centers. This is suitable for extended applications in the clamping of long shaft parts.

[0003] When machining long shaft parts, parts with irregular cross-sections need to be milled using a multi-axis machining center. Due to the poor rigidity and easy deformation of long shaft parts during machining, the structure and accuracy of the clamping fixture directly affect the machining accuracy and efficiency of the parts.

[0009] Preferably, the main slider has a second mounting hole at the end away from the secondary slider, the second mounting hole is connected to the first mounting hole, and the screw part of the fixing bolt passes through the second mounting hole and is located in the first mounting hole.

[0010] Preferably, the top cone is fixed to the slider by a locking bolt.

[0011] Preferably, the base is provided with a slide rail, and both the main slider and the auxiliary slider are slidably disposed on the slide rail.

Detailed Implementation

[0016] 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.

[0017] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0018] In this embodiment, refer to Figure 1 , Figure 2 and Figure 3The system includes a base 1, on which a slide rail 10 is provided. The slide rail 10 has a locking groove 11 along its length. There are two locking grooves 11, which are located on both sides of the slide rail 10 and are arranged in parallel. The base 1, the slide rail 10 and the locking groove 11 are integrally formed.

[0019] A main slider 2 is slidably mounted on the slide rail 10, and a secondary slider 3 is also slidably mounted on the slide rail 10. The main slider 2 and the secondary slider 3 are arranged opposite to each other. Both the main slider 2 and the secondary slider 3 have multiple threaded holes. The locking bolt 12 is threaded through the threaded holes and then locked into the locking groove 11 to fix the main slider 2 and the secondary slider 3. Loosening the locking bolt 12 will make it no longer locked in the locking groove 11, which will facilitate the movement of the main slider 2 and the secondary slider 3 and control the distance between the main slider 2 and the secondary slider 3 so as to clamp long shaft parts of different sizes.

[0020] To clamp the long shaft component between the main slider 2 and the secondary slider 3, refer to... Figure 1 A collet 4 is installed on the main slider 2, and a top cone 5 is installed on the auxiliary slider 3. The clamping end of the collet 4 and the top cone 5 are positioned opposite each other. When the long shaft part is placed between the collet 4 and the top cone 5, the collet 4 clamps one end of the long shaft part, and the top cone 5 presses against the other end of the long shaft, thus achieving the clamping of the long shaft part.

[0021] In this embodiment, refer to Figure 1 and Figure 4 The collet 4 is detachable. A first mounting hole 6 is provided at the end of the main slider 2 near the auxiliary slider 3. The collet 4 is installed in the first mounting hole 6 with clearance fit. A second mounting hole 8 is provided at the end of the main slider 2 away from the auxiliary slider 3. The second mounting hole 8 communicates with the first mounting hole 6. A fixing bolt 7 is installed in the second mounting hole 8. The threaded part of the fixing bolt 7 passes through the second mounting hole 8 and is located in the first mounting hole 6 and is threadedly connected to the collet 4.

[0022] Install the collet 4 in the first mounting hole 6, and insert the fixing bolt 7 into the second mounting hole 8. The threaded part of the fixing bolt 7 passes through the first mounting hole 6 and is threadedly connected to the rear end of the collet 4, thus fixing the collet 4 on the main slider 2. When the fixing bolt 7 is no longer threadedly connected to the collet 4, the collet 4 can be removed from the first mounting hole 6 to facilitate the installation and removal of the collet 4.

[0023] In this embodiment, refer to Figure 1 and Figure 5 The top cone 5 has a third mounting hole 13. The top cone 5 is installed in the third mounting hole 13. The locking bolt 9 passes through the third mounting hole 13 from the rear end of the auxiliary slider 3 and is threaded to the top cone 5, so that the top cone 5 is fixed to the auxiliary slider 3 by the locking bolt 9. The top cone 5 can be detachably installed on the auxiliary slider 3.

[0024] The working principle of this embodiment is as follows: The long shaft part is placed on the slide rail 10, and the long shaft part is located between the main slide 2 and the auxiliary slide 3. By moving the main slide 2 and the auxiliary slide 3 to both ends of the long shaft part, the collet 4 clamps one end of the long shaft part, and the top cone 5 presses against the other end of the long shaft part. Then, multiple snap-fit ​​bolts 12 are used to pass through the main slide 2 and the auxiliary slide 3 respectively and snap into the snap-fit ​​groove 11 to fix the main slide 2 and the auxiliary slide 3, thereby fixing the long shaft part on the base 1, realizing the clamping and fixing of the long shaft part. With the help of a multi-axis machining center, the clamping problem of long shaft parts is solved. The overall structure is simple, highly applicable, has high clamping accuracy, and strong clamping rigidity, solving the problem of difficult machining of long shaft parts.

[0025] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
