Description

Technical Field

[0001] This utility model relates to the technical field of titanium alloy metal parts processing equipment, and in particular to a fixture for processing titanium alloy metal parts. Background Technology

[0002] In the field of titanium alloy metal parts processing, with the increasing demand for titanium alloy products from industries such as aerospace, medical devices, and automobile manufacturing, the requirements for the processing accuracy and quality of titanium alloy metal parts are becoming increasingly stringent. Titanium alloys have many excellent properties such as low density, high strength, and corrosion resistance, but they also bring the problem of high processing difficulty, especially in the clamping process of parts.

[0003] In the clamping process, different shapes of titanium alloy metal parts require different clamping methods during processing. Existing titanium alloy metal part processing fixtures are often designed for specific shapes of parts and have poor versatility. When a company needs to process titanium alloy parts of various shapes, it needs to equip itself with a variety of different types of fixtures. This not only increases the company's equipment procurement costs but also occupies a lot of production space. At the same time, frequent fixture changes also waste a lot of time and manpower and reduce production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fixture for machining titanium alloy metal parts, which has the advantage of wide applicability and solves the problem that existing fixtures for machining titanium alloy metal parts are often designed for parts with specific shapes and have poor versatility.

[0005] This utility model provides the following technical solution: a fixture for machining titanium alloy metal parts, comprising a base, a column, and a top plate. A clamping assembly is disposed above the base. The clamping assembly includes a cylinder fixedly connected to the top surface of the base. A guide column is fixedly connected to the top surface of the base. A conical block is slidably connected to the surface of the guide column. A connecting groove is evenly formed on the surface of the conical block. An arc-shaped block is evenly arranged inside the conical block. A fixing block is fixedly connected to one end of each arc-shaped block. A connecting rod is fixedly connected to the top surface of each fixing block. A limit bearing is provided on the surface of each connecting rod. The top plate has evenly formed... The system includes a sliding groove, guide grooves evenly distributed inside the top plate, stop blocks fixedly connected to the surface of each connecting rod, clamping blocks provided on the surface of each connecting rod, and a placement platform fixedly connected to the center surface of the top of the top plate. A connecting assembly is provided between the clamping blocks and the connecting rods. When the cylinder drives the conical blocks to move, the special conical structure of the conical blocks causes the arc-shaped blocks to move synchronously closer or further apart within the connecting groove, thereby driving the connecting rods and clamping blocks to clamp or release the parts. This clamping method can ensure that the parts remain stable during processing, reduce processing errors caused by vibration or uneven force, and improve processing accuracy and product quality.

[0006] Preferably, the four columns are evenly fixedly connected between the opposite surfaces of the base and the top plate, the extension shaft of the cylinder is fixedly connected to the bottom surface of the conical block through a coupling, the arc-shaped blocks are all slidably connected inside the connecting groove, and the connecting rods are all slidably connected inside the sliding groove. The connecting groove plays a guiding and restricting role for the arc-shaped blocks.

[0007] Preferably, the limiting bearings are all slidably connected inside the guide groove. The number of connecting grooves, arc-shaped blocks, fixing blocks, connecting rods, limiting bearings, sliding grooves, guide grooves, stop blocks, and clamping blocks are the same, and there are at least four sets. Multiple sets of clamping blocks move synchronously to perform synchronous centering and clamping of the titanium alloy metal parts to be processed, so that the titanium alloy metal parts to be processed are subjected to uniform force and the clamping force is reduced to reduce the damage to the titanium alloy metal parts to be processed.

[0008] Preferably, the connecting assembly includes a limiting plate fixedly connected to the surface of the connecting rod, a positioning rod fixedly connected to the top surface of the limiting plate, a connecting sleeve slidably fitted onto the surface of each connecting rod, an arc-shaped groove formed on the inner wall surface of the connecting sleeve, a snap-fit ​​groove formed on the top surface of the connecting sleeve, an installation groove formed on the top surface of each connecting rod, a tension spring provided inside each connecting rod, a slider fixedly connected to the top surface of each tension spring, a pull block rotatably connected to the top surface of the slider, a snap-fit ​​block fixedly connected to the side wall surface of the pull block, a positioning groove formed on the bottom surface of the connecting sleeve, and a clamping block fixedly connected to the surface of the connecting sleeve. This connecting assembly design facilitates individual replacement of each clamping block, eliminating the need to replace the entire fixture when a single clamping block is damaged, thus reducing enterprise maintenance costs.

[0009] Preferably, the bottom of each connecting sleeve abuts against the top surface of the limiting plate, and each connecting sleeve is slidably connected to the surface of the positioning rod through a positioning groove. The arc-shaped groove and the snap-fit ​​block are mutually adapted, and the size of the arc-shaped groove is slightly larger than the size of the snap-fit ​​block.

[0010] Preferably, the snap-fit ​​groove and the snap-fit ​​block are mutually adapted, the bottom of the tension spring is fixedly connected to the bottom inner wall surface of the mounting groove, and the slider is slidably connected inside the mounting groove. The cooperation between the snap-fit ​​groove and the snap-fit ​​block realizes the fixation of the clamping block.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By using the clamping and connecting components together, the titanium alloy metal parts to be machined are stably centered and clamped. The cylinder drives the conical block to move, which in turn drives the connecting rod and clamping block to clamp or release the parts. This ensures that the parts remain stable during processing, reduces processing errors caused by vibration or uneven force, and improves processing accuracy and product quality. At the same time, users can quickly change the appropriate clamping block according to the shape of the parts to be machined, which greatly improves the applicability of the fixture, reduces the cost and time of changing fixtures due to different part shapes, and improves production efficiency.

[0013] 2. By setting the stop, when the connecting rod moves in the slide groove during the operation of the fixture, the stop also moves. During the movement, it will automatically scrape off the metal debris remaining above the slide groove, preventing the metal debris from accumulating above the slide groove and hindering the normal movement of the connecting rod, which could lead to inaccurate clamping or fixture damage. This ensures the long-term stable operation of the fixture, reduces the maintenance cost and downtime of the fixture, and also improves the service life of the fixture. Attached Figure Description

Detailed Implementation

[0018] 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.

[0019] Please see Figures 1-3This utility model provides an embodiment of a fixture for machining titanium alloy metal parts, comprising a base 1, a column 2, and a top plate 3. A clamping assembly 4 is disposed above the base 1. The clamping assembly 4 includes a cylinder 41 fixedly connected to the top surface of the base 1. A guide column 42 is fixedly connected to the top surface of the base 1. A conical block 43 is slidably connected to the surface of the guide column 42. A connecting groove 44 is evenly formed on the surface of the conical block 43. An arc-shaped block 45 is evenly formed inside the conical block 43. A fixing block 46 is fixedly connected to one end of each arc-shaped block 45. A connecting rod 47 is fixedly connected to the top surface of each fixing block 46. A limit bearing 48 is provided on the surface of each connecting rod 47. A sliding groove 49 is evenly formed on the surface of the top plate 3. A guide groove 411 is evenly formed inside the top plate 3. Each connecting rod 47 has a stop block 412 fixedly connected to its surface, and each connecting rod 47 has a clamping block 413. A placement platform 414 is fixedly connected to the center surface of the top plate 3. A connecting assembly 5 is provided between the clamping block 413 and the connecting rod 47. Four columns 2 are evenly fixedly connected between the opposite surfaces of the base 1 and the top plate 3. The extension shaft of the cylinder 41 is fixedly connected to the bottom surface of the conical block 43 through a coupling. The arc-shaped blocks 45 are all slidably connected inside the connecting groove 44. Each connecting rod 47 is all slidably connected inside the slide groove 49. Each limiting bearing 48 is all slidably connected inside the guide groove 411. The connecting groove 44, arc-shaped blocks 45, fixing blocks 46, connecting rods 47, limiting bearings 48, slide grooves 49, guide grooves 411, stop blocks 412, and clamping blocks are all present. The number of 413 is the same, and there are at least four sets. When clamping the titanium alloy metal parts to be processed, the titanium alloy metal parts to be processed are first placed on the top surface of the placement table 414. At this time, the extension shaft of the cylinder 41 is in the straight state. After the titanium alloy metal parts to be processed are placed, the cylinder 41 is started, so that the extension shaft of the cylinder 41 gradually retracts. As the extension shaft of the cylinder 41 gradually retracts, it will drive the conical block 43 to move towards the cylinder 41. When the conical block 43 moves, it will drive the arc block 45 to move inside the connecting groove 44. Since the conical block 43 has a conical structure, that is, the diameter of the top end is smaller than the diameter of the bottom end, as the conical block 43 moves, the arc block 45 moves closer to each other synchronously, thereby driving the connecting rod 47 to move synchronously towards the placement table through the fixing block 46. As the platform 414 moves, the limiting bearing 48 moves within the guide groove 411 during the movement of the connecting rod 47, limiting the connecting rod 47 and preventing it from moving up and down. Simultaneously, the connecting rod 47 drives the stop block 412 and the clamping block 413 to move towards the platform 414, thus achieving stable centering and clamping of the titanium alloy metal part to be processed. The titanium alloy metal part can then be processed. After processing, the drive cylinder 41 straightens. At this time, the connecting rod 47 simultaneously drives the stop block 412 and the clamping block 413 to move away from the platform 414, releasing the processed titanium alloy metal part. During this process, because the stop block 412 is positioned above the slide groove 49...Therefore, during the movement of the stop 412, residual metal shavings from machining above the slide groove 49 can be scraped off, preventing the metal shavings from obstructing the movement of the connecting rod 47.

[0020] Please see Figures 1-3 The connecting assembly 5 includes a limiting plate 51 fixedly connected to the surface of the connecting rod 47. A positioning rod 52 is fixedly connected to the top surface of the limiting plate 51. Connecting sleeves 53 are slidably sleeved on the surface of the connecting rod 47. Arc-shaped grooves 54 are formed on the inner wall surface of the connecting sleeves 53. A snap-fit ​​groove 55 is formed on the top surface of the connecting sleeves 53. Mounting grooves 56 are formed on the top surface of the connecting rod 47. A tension spring 57 is provided inside the connecting rod 47. A slider 58 is fixedly connected to the top surface of the tension spring 57. A pull block 59 is rotatably connected to the top surface of the slider 58. A snap-fit ​​block is fixedly connected to the side wall surface of the pull block 59. 511, the bottom surface of the connecting sleeve 53 is provided with positioning grooves 512, the clamping block 413 is fixedly connected to the surface of the connecting sleeve 53, the bottom of the connecting sleeve 53 abuts against the top surface of the limiting plate 51, the connecting sleeve 53 is slidably connected to the surface of the positioning rod 52 through the positioning grooves 512, the arc groove 54 is adapted to the snap-fit ​​block 511, the snap-fit ​​groove 55 is adapted to the snap-fit ​​block 511, the bottom of the tension spring 57 is fixedly connected to the bottom inner wall surface of the mounting groove 56, and the slider 58 is slidably connected inside the mounting groove 56. Through the setting of the connecting component 5, if the titanium alloy metal part to be processed is a square structure At this point, pull the pull block 59 upwards, which will cause the tension spring 57 to stretch via the slider 58. The locking block 511 will then disengage from the locking groove 55, releasing the restriction on the connecting sleeve 53. Next, rotate the pull block 59 so that the locking block 511 and the arc-shaped groove 54 are aligned vertically. Release the pull block 59, and under the reset action of the tension spring 57, the locking block 511 will slide into the arc-shaped groove 54. Then, pull the connecting sleeve 53 upwards to remove the clamping block 413 from the surface of the connecting rod 47. Then, according to the part requirements, replace it with a square clamping block 413. When replacing the clamping block 413, ensure the positioning groove... The surface of the positioning rod 52 is slidably connected to the positioning rod 52. Then, the lifting block 59 is lifted, and the locking block 511 will disengage from the inside of the arc groove 54. Then, the lifting block 59 is rotated so that the locking block 511 and the locking groove 55 are on the same vertical line. The lifting block 59 is released, and under the reset action of the tension spring 57, the locking block 511 is locked into the inside of the locking groove 55, thereby restricting the connecting sleeve 53. The positioning groove 512 and the positioning rod 52 can prevent the clamping block 413 from rotating during use. Through the setting of the connecting component 5, it is convenient to quickly replace each individual clamping block 413 according to processing requirements or damage to the clamping block 413.

[0021] Working principle: When clamping the titanium alloy metal parts to be processed, the parts are first placed on the placement platform 414 fixedly connected to the center surface of the top plate 3. At this time, the extension shaft of the cylinder 41 is in the straight state. Then, the cylinder 41 is started, and the extension shaft of the cylinder 41 gradually retracts. Since the extension shaft of the cylinder 41 is fixedly connected to the bottom surface of the conical block 43 through a coupling, it will drive the conical block 43 to move along the guide post 42 towards the cylinder 41. The surface of the conical block 43 is evenly provided with connecting grooves 44, and the interior is evenly provided with arc-shaped blocks 45. The arc-shaped blocks 45 are slidably connected inside the connecting grooves 44, and the conical block 43 has a conical structure with the top diameter smaller than the bottom diameter. As the conical block 43 moves, the arc-shaped blocks... The arc-shaped blocks 45 move synchronously closer to each other within the connecting groove 44. As the arc-shaped blocks 45 move, they drive the connecting rod 47 to move synchronously towards the placement platform 414 via the fixing block 46. The limit bearing 48 moves within the guide groove 411 to limit the connecting rod 47, preventing it from moving up and down. As the connecting rod 47 moves, it synchronously drives the stop block 412 and the clamping block 413 to move towards the placement platform 414, achieving stable centering and clamping of the titanium alloy metal part. Afterward, the part can be processed. Once processing is complete, the drive cylinder 41 extends, and the cylinder 41's extension shaft drives the conical block 43 to move away from the cylinder 41. The arc-shaped blocks 45 move synchronously away from each other within the connecting groove 44, and then, via the fixing block 46... The connecting rod 47 moves away from the placement table 414, causing the stop block 412 and clamping block 413 to move synchronously, releasing the machined part. During this process, the stop block 412 scrapes away any remaining metal debris above the slide groove 49 to prevent it from obstructing the movement of the connecting rod 47. When the titanium alloy metal part to be machined is square, the clamping block 413 can be replaced via the connecting assembly 5. To replace it, pull the pull block 59 upwards, causing the slider 58 to pull the tension spring 57, thus disengaging the locking block 511 from the locking groove 55 and removing the restriction on the connecting sleeve 53. Then, rotate the pull block 59 to engage the locking block 511 with the arc. With the arc groove 54 aligned with the vertical line, release the pull block 59. Under the reset action of the tension spring 57, the snap-fit ​​block 511 slides into the arc groove 54. Then, pull the connecting sleeve 53 upwards and remove the clamping block 413 from the surface of the connecting rod 47. Replace it with a square clamping block 413 according to the part requirements. When replacing, make the positioning groove 512 slide and connect with the surface of the positioning rod 52. Lift the pull block 59, and the snap-fit ​​block 511 will disengage from the arc groove 54. Rotate the pull block 59 so that the snap-fit ​​block 511 and the snap-fit ​​groove 55 are aligned with the vertical line. Release the pull block 59. Under the reset action of the tension spring 57, the snap-fit ​​block 511 snaps into the snap-fit ​​groove 55, thereby restricting the connecting sleeve 53 and completing the replacement of the clamping block 413.
