[0025] Example 1, as Figures 1-5As shown in the figure, the utility model provides a five-axis horizontal machining center fixture, including: a fixture main body 1, on the outer surface of the fixture main body 1 is fixedly connected with a motor 2, the output end of the motor 2 rotatably penetrates through the outer surface of the fixture main body 1, the output end of the motor 2 is fixedly connected with a bidirectional threaded rod 3, and a clamping assembly 4 is arranged on the outer surface of the bidirectional threaded rod 3; the clamping assembly 4, the clamping assembly 4 is provided with two groups, the two groups of clamping assemblies 4 are symmetrically arranged on the outer surface of the bidirectional threaded rod 3, the clamping assembly 4 includes a moving block 401, the inner surface of the moving block 401 is in threaded rotational connection with the outer surface of the bidirectional threaded rod 3, the top of the moving block 401 is fixedly connected with a connecting block 402, the inner surface of the connecting block 402 is provided with a first connecting rod 406 in a matching manner, the bottom of the first connecting rod 406 is fixedly connected with a first pushing block 413, the first pushing block 413 and the connecting block 402 are in a matching setting, a first spring 404 is sleeved on the outer surface of the first connecting rod 406, the top of the first connecting rod 406 is fixedly connected with a mounting block 403, clamping blocks 414 are arranged on the outer surfaces of both sides of the mounting block 403 in a matching manner, first fixing holes 415 are opened on the front surfaces of the two clamping blocks 414, a second pushing block 412 is slidably connected to the inner surface of the mounting block 403, a second connecting rod 411 is fixedly connected to the front surface of the second pushing block 412, the outer surface of the second connecting rod 411 slidably penetrates through the inner surface of the mounting block 403, a mounting plate 407 is fixedly connected to the front surface of the second connecting rod 411, a second spring 410 is sleeved on the outer surface of the second connecting rod 411, limiting blocks 409 are symmetrically fixedly connected to the rear surface of the mounting plate 407, second fixing holes 416 are symmetrically opened on the front surface of the mounting block 403, the second fixing holes 416 and the first fixing holes 415 are in a matching setting, the limiting blocks 409 are located inside the first fixing holes 415 and the second fixing holes 416, the limiting blocks 409 and the first fixing holes 415 and the second fixing holes 416 are in a matching setting, the first spring 404 is located inside the connecting block 402, the first spring 404 and the connecting block 402 are in a matching setting, the second spring 410 is located inside the mounting block 403, the second spring 410 and the second pushing block 412 are in a matching setting, the outer surface of the bidirectional threaded rod 3 away from the motor 2 rotatably penetrates through the inner surface of the fixture main body 1, the bidirectional threaded rod 3 is rotatably connected to the fixture main body 1, the height of the first guiding rod 405 is less than the height of the first connecting rod 406, and the length of the limiting block 409 is less than the length of the second connecting rod 411.

[0026] The effect achieved by the entire Embodiment 1 is that when the fixture of the five-axis horizontal machining center is in use, the motor 2 is started, and the output end of the motor 2 drives the bidirectional threaded rod 3 to rotate correspondingly inside the inner wall of the fixture main body 1. The two moving blocks 401 will drive the two groups of fixtures to move towards or away from each other respectively, playing a role in clamping and fixing the workpiece. When replacing the fixture, the pull rods on the outer sides of the two mounting plates 407 are pulled in sequence. The second connecting rod 411 drives the second pushing block 412 to move outwards, and squeezes the second spring 410, causing it to deform and contract. The two limiting blocks 409 shorter than the second connecting rod 411 will slide out from the two first fixing holes 415 and the two second fixing holes 416, playing a role in releasing the limit on the two clamping blocks 414. Hold the two clamping blocks 414 and pull them upwards in sequence, so that they slide out on the outer surface of the mounting block 403. Insert the two clamping blocks 414 to be replaced downwards along the outer surfaces on both sides of the mounting block 403 respectively, and make their bottoms respectively abut against the inner bottom of the mounting block 403 to play a positioning role. At this time, the positions of the first fixing holes 415 and the second fixing holes 416 are aligned. Release the pull on the pull rod on the outer side of the mounting plate 407. Under the elastic reset action of the second spring 410, the second pushing block 412 is pushed, driving the two limiting blocks 409 to insert into the second fixing holes 41 six and the first fixing holes 415 in sequence, playing a limiting role, so that the two replaced clamping blocks 414 are fixed on both sides of the mounting block 403. When clamping different workpieces, hold the two mounting blocks 403 and lift them upwards in sequence. The first connecting rod 406 fixedly connected to the bottom thereof will drive the first pushing block 413 to slide upwards in the connecting block 402. The first pushing block 413 will squeeze the first spring 404, causing it to deform and contract. At this time, keep lifting the corresponding mounting block ^^^^^3 and rotate it horizontally by 180 degrees, so that its first pushing block 413 and the first connecting rod 406 will rotate synchronously in the connecting block 402. After the positions of the two clamping blocks 414 are swapped, release the lift on the mounting block 403. Under the elastic reset action of the first spring 404, the mounting block 403 is driven to fit against the top of the connecting block 402, and the first guide rods 405 symmetrically arranged at the bottom thereof will correspondingly insert into the connecting block 402 for limiting. Through the coordinated adjustment of the two groups of clamping assemblies 4, the role of quickly adjusting the fixture is played to adapt to workpieces of different shapes, avoiding the need to frequently replace the fixture in a short time, increasing the processing time of the workpiece, and improving the processing efficiency of the fixture of the five-axis horizontal machining center.

[0027] Embodiment 2, as Figures 1-5 shown, the rear surface of the mounting plate 407 is symmetrically and fixedly connected with second guide rods 408. The outer surfaces of the second guide rods 408 are slidably connected with the inner surfaces of the mounting blocks 403. The bottoms of the mounting blocks 403 are symmetrically and fixedly connected with first guide rods 405. The outer surfaces of the first guide rods 405 are slidably connected with the inner surfaces of the connecting blocks 402.

[0028] The effect achieved by the entire Embodiment 2 is that during use, by symmetrically and fixedly arranging second guide rods 408 on the rear surface of the mounting plate 407, with their lengths being the same as that of the second connecting rod 411, it can play a guiding role when replacing the clamping block 414, enabling the two limit blocks 409 to be quickly inserted into the first fixing hole 415 and the second fixing hole 416 corresponding in position for limiting, thus improving the replacement efficiency of the fixture of the five-axis horizontal machining center.

[0029] Working principle: When the fixture of a five-axis horizontal machining center is in use, start the motor 2. The output end of the motor 2 drives the bidirectional threaded rod 3 to rotate correspondingly inside the inner wall of the fixture main body 1. The two moving blocks 401 will drive the two groups of fixtures to move towards or away from each other respectively, playing a role in clamping and fixing the workpiece. When replacing the fixture, pull the pull rods on the outer sides of the two mounting plates 407 in sequence. The second connecting rod 411 drives the second pushing block 412 to move outwards, and squeezes the second spring 410, causing it to deform and contract. The two limiting blocks 409 shorter than the second connecting rod 411 will slide out from the two first fixing holes 415 and the two second fixing holes 416, playing a role in releasing the limit on the two clamping blocks 414. Hold the two clamping blocks 414 and pull them upwards in sequence, so that they slide out on the outer surface of the mounting block 403. Slide the two clamping blocks 414 to be replaced downwards along the outer surfaces on both sides of the mounting block 403 respectively, and make their bottoms respectively abut against the inner bottom of the mounting block 403 to play a positioning role. At this time, the positions of the first fixing holes 415 and the second fixing holes 416 are aligned. Release the pulling of the pull rods on the outer sides of the mounting plates 407. Under the elastic reset action of the second spring 410, push the second pushing block 412, driving the two limiting blocks 409 to insert into the second fixing holes 416 and the first fixing holes 415 in sequence, playing a limiting role, so that the two replaced clamping blocks 414 are fixed on both sides of the mounting block 403. When clamping different workpieces, hold the two mounting blocks 403 and lift them upwards in sequence. The first connecting rod 406 fixedly connected to the bottom will drive the first pushing block 413 to slide upwards in the connecting block 402. The first pushing block 413 will squeeze the first spring 404, causing it to deform and contract. At this time, keep lifting the corresponding mounting block 403 and rotate it horizontally by 180 degrees, so that its first pushing block 413 and the first connecting rod 406 will rotate synchronously in the connecting block 402. After the positions of the two clamping blocks 414 are swapped, release the lifting of the mounting block 403. Under the elastic reset action of the first spring 404, drive the mounting block 403 to fit against the top of the connecting block 402, and the first guide rods 405 symmetrically arranged at the bottom will correspondingly insert into the connecting block 402 for limiting. Since the outer surface shapes of the two groups of multiple clamping blocks 414 are different, the two groups of clamping blocks 414 after the position swap can quickly clamp the suitable workpiece, avoiding the need to frequently replace the clamping structure and affecting the processing efficiency. By symmetrically and fixedly arranging the second guide rods 408 on the rear surface of the mounting plate 407, and their lengths are the same as the length of the second connecting rod 411, it can play a guiding role when replacing the clamping blocks 414, enabling the two limiting blocks 409 to quickly insert into the first fixing holes 415 and the second fixing holes 416 with corresponding positions for limiting, improving the replacement efficiency of the fixture of the five-axis horizontal machining center.

[0030] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
