Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a fixture suitable for mass production in vertical machining centers. Background Technology

[0002] In mass production scenarios using vertical machining centers, fixtures, as key components connecting machine tools and parts, directly affect machining quality.

[0003] Based on the above, the inventors have discovered the following problems: Most existing fixtures use clamping plates to hold and fix cylindrical parts. However, when grooving the outside of cylindrical parts, existing fixtures need to continuously change the position of the parts in the fixture because grooving operations need to be performed at different positions on the outside of the parts. During the repeated fixing of the parts by the fixture, the fixture may have problems such as inaccurate positioning and unstable clamping, resulting in large deviations in the processing results.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a fixture suitable for mass production of vertical machining centers, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a fixture suitable for mass production in vertical machining centers, so as to solve the problems mentioned in the background art, which are that the existing fixtures repeatedly fix parts, resulting in inaccurate positioning and unstable clamping, leading to large deviations in the machining results.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A fixture suitable for mass production in vertical machining centers includes a mounting mechanism, a part body, and a fixing mechanism. The mounting mechanism includes a mounting base, a connecting shaft fixedly mounted at the center of one end of the mounting base, and a shaft core fixedly mounted at the center of the other end of the mounting base. A connector is mounted at one end of the shaft core. The part body is movably sleeved on the outside of the shaft core, and one end of the part body abuts against the mounting base. The fixing mechanism includes a pressure cap, which is movably sleeved on the outside of the connector. A stepped hole is formed at the center of the pressure cap, one end of which abuts against one end of the shaft core, and one side of the pressure cap abuts against the other end of the part body. One end of the connector extends outward through the stepped hole.

[0008] Furthermore, a insertion groove is provided on the outer side of one end of the shaft core, and a positioning pin is interference-fitted into the inside of the insertion groove.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the locating pin is interference-fitted into the insertion groove of the shaft core, providing a circumferential positioning reference for the gland, preventing the gland from rotating and shifting during the clamping process, and ensuring the accuracy and consistency of the clamping position of the part body.

[0010] Furthermore, a positioning groove is provided on the outer side of one end of the stepped hole, and the positioning groove is inserted into the positioning pin.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the positioning groove and the positioning pin are inserted to enable the pressure cover to be positioned on the shaft core, avoiding uneven force on the part body due to installation errors, and ensuring the dimensional accuracy and processing quality of the part body during batch processing.

[0012] Furthermore, the outer side of the cover is provided with several grippers, which are circumferentially distributed at equal intervals along the axis of the cover.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the circumferentially distributed grippers apply clamping force to the part body from multiple directions, enhancing clamping stability and preventing the part from shifting due to cutting force during processing.

[0014] Furthermore, each of the grippers is provided with a feed groove.

[0015] The beneficial effects of adopting the above-mentioned further solution are that the infeed groove provides machining space for the tool, avoids interference of the gripper with the tool path, ensures that the tool can smoothly cut the part body, and improves machining efficiency and safety.

[0016] Furthermore, it also includes a locking mechanism, which includes a locking nut and a washer. The washer is sleeved on one end of the connector, and the locking nut is threaded to one end of the connector.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the washer and locking nut of the locking mechanism cooperate to firmly fix the gland to the connector, increase the clamping force, prevent the gland from loosening during processing, and ensure the reliability of the clamping of the part body.

[0018] Furthermore, one side of the washer abuts against one side of the gland, and one side of the locking nut abuts against the other side of the washer.

[0019] The beneficial effects of adopting the above-mentioned further solution are that the washer plays a role in buffering and uniformly transmitting pressure, avoiding direct pressure of the locking nut on the gland and causing surface damage; at the same time, the contact between the washer and the gland and the locking nut further enhances the locking effect and ensures the stability of the fixture in batch processing.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This fixture, suitable for mass production in vertical machining centers, has a mounting base that can be fixed to the three-jaw chuck of the vertical machining center via a connecting shaft, with the shaft core providing positioning support for the part body; the pressure cap of the fixing mechanism is fitted onto the connecting head and, through a stepped hole, engages with the shaft core to clamp the part body between the mounting base and the pressure cap, achieving rapid positioning and fixing of the part, facilitating mass production in vertical machining centers; the positioning pin is interference-fitted into the insertion groove of the shaft core, providing a circumferential positioning reference for the pressure cap, preventing rotational displacement of the pressure cap during clamping, ensuring the accuracy and consistency of the clamping position of the part body; the circumferentially distributed jaws apply clamping force to the part body from multiple directions, enhancing clamping stability and preventing displacement of the part due to cutting force during machining; the washer and locking nut of the locking mechanism work together to firmly fix the pressure cap to the connecting head, increasing the clamping force, preventing the pressure cap from loosening during machining, and ensuring the reliability of the part body clamping.

[0031] 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.

[0032] Please see Figures 1-4A insertion groove 106 is provided on the outer side of one end of the shaft core 103. A positioning pin 104 is interference-fitted into the insertion groove 106. A positioning groove 303 is provided on the outer side of one end of the stepped hole 305. The positioning groove 303 is interlocked with the positioning pin 104. Several grippers 302 are provided on the outer side of the pressure cover 301. The grippers 302 are circumferentially distributed at equal intervals along the axis of the pressure cover 301. A feed groove 304 is provided between adjacent grippers 302.

The accuracy and consistency of the clamping position: The positioning groove 303 is inserted into the positioning pin 104, so that the pressure cap 301 is positioned on the shaft core 103, avoiding uneven force on the part body 2 due to installation errors, ensuring the dimensional accuracy and machining quality of the part body 2 during batch processing. The circumferentially distributed jaws 302 apply clamping force to the part body 2 from multiple directions, enhancing clamping stability and preventing displacement of the part due to cutting force during processing. The tool inlet groove 304 provides machining space for the tool, avoiding interference of the jaws 302 with the tool path, ensuring that the tool can smoothly cut the part body 2, improving machining efficiency and safety.

[0033] 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.

[0034] Please see Figures 1-4 The system also includes a locking mechanism 4, which comprises a locking nut 401 and a washer 402. The washer 402 is fitted onto one end of the connector 105, and the locking nut 401 is threadedly connected to one end of the connector 105. One side of the washer 402 abuts against one side of the pressure cap 301, and one side of the locking nut 401 abuts against the other side of the washer 402. The washer 402 and the locking nut 401 of the locking mechanism 4 cooperate to firmly fix the pressure cap 301 onto the connector 105, increasing the clamping force and preventing the pressure cap 301 from loosening during processing, thus ensuring the reliability of the clamping of the part body 2. The washer 402 plays a role in buffering and uniformly transmitting pressure, preventing the locking nut 401 from directly squeezing the pressure cap 301 and causing surface damage. At the same time, the contact between the washer 402 and the pressure cap 301 and the locking nut 401 further enhances the locking effect, ensuring the stability of the fixture in batch processing.

[0035] Specifically, the working principle of this fixture suitable for mass production in vertical machining centers is as follows: First, it is fixed to the three-jaw chuck of the vertical machining center via the connecting shaft 102 on the mounting base 101, ensuring the mounting mechanism 1 is stable. Then, the part body 2 is fitted onto the outside of the shaft core 103, with one end abutting against the mounting base 101 for initial positioning. Next, the pressure cap 301 is fitted onto the connector 105. At this time, the positioning groove 303 on the outside of the stepped hole 305 of the pressure cap 301 engages with the positioning pin 104 in the insertion groove 106 of the shaft core 103, ensuring accurate circumferential positioning of the pressure cap 301 and preventing the part body 2 from being misaligned during clamping. Next, the washer 402 is placed on the connector 105, so that one side of it abuts against the cover 301. Then, the locking nut 401 is screwed on, and the cover 301 is firmly fixed to the connector 105 through the threaded connection. Multiple circumferentially distributed jaws 302 apply clamping force to the part body 2 from different directions. Since there are feed grooves 304 between the jaws 302, the tool can avoid the jaws 302 during the machining process and cut the part body 2 along the set path. After the machining is completed, the locking nut 401 is loosened and the cover 301 is removed, so that the part body 2 can be quickly replaced, realizing the mass production of the vertical machining center.
