Description

Technical Field

[0001] This utility model relates to the technical field of centrifugal nozzle processing equipment, and in particular to a positioning fixture for centrifugal nozzle processing. Background Technology

[0002] Currently, positioning fixtures for centrifugal nozzle processing are devices used to precisely position and clamp nozzle workpieces during the centrifugal nozzle processing process to ensure processing accuracy and quality.

[0003] Existing tooling fixtures mostly use fasteners such as bolts for installation and fixation. When changing the fixture components corresponding to different specifications of centrifugal nozzles, it is necessary to disassemble or install bolts one by one, which is cumbersome, time-consuming and affects processing efficiency. At the same time, some fixtures lack stable limiting structures after positioning. During processing, the fixture components are prone to displacement due to vibration, which affects the processing quality of centrifugal nozzles and cannot meet the requirements of efficient and precise processing. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a positioning fixture for centrifugal nozzle processing.

[0005] This utility model is achieved using the following technical solution: a positioning fixture for centrifugal nozzle processing, comprising a base plate, a fixture assembly capable of positioning and holding the centrifugal nozzle on the top of the base plate, a fixing assembly capable of quickly installing and disassembling the fixture assembly on the top of the base plate, and a limiting assembly capable of restricting the position of the fixing assembly on the top of the base plate. The fixing assembly includes a plurality of first sliding grooves arranged in a circular array on the top of the base plate, and a plurality of second sliding grooves arranged in a circular array on the bottom of the fixture assembly. The opening of each second sliding groove is connected to the opening of an adjacent first sliding groove. Each first sliding groove and each second sliding groove is T-shaped. An I-shaped block is slidably disposed inside each first sliding groove, and the top end of the I-shaped block extends into the interior of an adjacent second sliding groove and slides in cooperation with it.

[0006] Through the above technical solution, the first and second sliding grooves of the "T" shape can restrict the sliding direction of the I-shaped block and prevent the I-shaped block from disengaging from the sliding groove; the I-shaped block can cooperate with the first and second sliding grooves to fix the fixture assembly on the base plate, so as to realize the quick replacement of the fixture assembly.

[0007] As a further improvement to the above solution, the limiting component includes multiple limiting grooves arranged in a ring array on the top of the base plate. A push plate is slidably disposed inside each limiting groove. A stop bar is fixedly installed on the top of each push plate. The top of each stop bar extends upward to the outside of the limiting groove. A limiting plate in the shape of an I-shaped block for controlling the position of the I-shaped block is fixedly installed on one side. One side of each limiting plate is in contact with the clamping assembly. Both ends of the top of each limiting plate are in contact with the side of the adjacent stop bar near the clamping assembly.

[0008] Through the above technical solution, the stop bar can restrict the position of the limiting plate, prevent the I-shaped block from sliding during processing, and thus prevent the fixture assembly from shifting; at the same time, the limiting plate fits into the fixture assembly, which can further enhance the stability of the fixture assembly after installation.

[0009] As a further improvement to the above solution, each of the limiting grooves is provided with two first springs inside, and the two ends of each first spring are fixedly installed with the adjacent push plate and the inner wall of the limiting groove, respectively.

[0010] Through the above technical solution, the first spring can generate elastic thrust on the push plate, so that the stop bar always remains in contact with the limiting plate, ensuring the continuity of the limiting effect.

[0011] As a further improvement to the above solution, each of the first sliding grooves is provided with a limiting rod inside, and each of the I-shaped blocks is slidably sleeved on the adjacent limiting rod.

[0012] Through the above technical solution, the limiting rod can guide the sliding direction of the I-shaped block, prevent the I-shaped block from shifting or getting stuck in the first sliding groove, ensure smooth sliding of the I-shaped block, and further improve the convenience of disassembly and assembly of the fixture assembly.

[0013] As a further improvement to the above solution, each of the limiting rods is fitted with a second spring, and the two ends of each second spring abut against the adjacent limiting plate and the inner wall of the first sliding groove, respectively.

[0014] Through the above technical solution, the second spring can generate an elastic thrust on the limiting plate, so that the I-shaped block always tends to move towards the clamping assembly, which enhances the tightness of the fit between the I-shaped block and the second sliding groove and further prevents the clamping assembly from loosening.

[0015] As a further improvement to the above solution, a concave limiting strip is fixedly installed on the top of each limiting groove, and a hook plate is rotatably installed on one side of each limiting plate. One end of each hook plate is concave, and each hook plate is adapted to the adjacent limiting strip.

[0016] Through the above technical solution, the movable limiting plate pulls the I-shaped block out of the second sliding groove, and then the hook plate is rotated to engage with the limiting strip, which can fix the limiting plate a second time and facilitate the replacement of the clamping assembly.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention enables quick assembly and disassembly of the clamping assembly through a fixing component. By utilizing the cooperation between the "T" shaped groove and the I-shaped block, bolts are not required for assembly and disassembly, which greatly improves the replacement efficiency and solves the problem of cumbersome assembly and disassembly of traditional clamps.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Please combine Figures 1-3 This embodiment provides a positioning fixture for processing centrifugal nozzles, including a base plate 1. The top of the base plate 1 is provided with a clamping assembly 2 capable of positioning and holding the centrifugal nozzle. The top of the base plate 1 is provided with a fixing assembly capable of quickly installing and disassembling the clamping assembly 2. The top of the base plate 1 is provided with a limiting assembly capable of restricting the position of the fixing assembly.

[0022] The fixing component includes multiple first sliding grooves 301 arranged in a ring array on the top of the base plate 1, and multiple second sliding grooves 302 arranged in a ring array on the bottom of the clamping component 2. The opening of each second sliding groove 302 is connected to the opening of the adjacent first sliding groove 301. Each first sliding groove 301 and second sliding groove 302 is arranged in a "T" shape. An I-shaped block 303 is slidably disposed inside each first sliding groove 301. The top end of the I-shaped block 303 extends into the interior of the adjacent second sliding groove 302 and slides with it.

[0023] The "T"-shaped first sliding groove 301 and second sliding groove 302 can restrict the sliding direction of the I-shaped block 303 and prevent the I-shaped block 303 from disengaging from the sliding groove; the I-shaped block 303 can cooperate with the first sliding groove 301 and second sliding groove 302 to fix the clamp assembly 2 on the base plate 1, so as to realize the quick replacement of the clamp assembly 2.

[0024] The limiting component includes multiple limiting grooves 401 arranged in a ring array on the top of the base plate 1. A push plate 402 is slidably disposed inside each limiting groove 401. A stop bar 403 is fixedly installed on the top of each push plate 402. The top of each stop bar 403 extends upward to the outside of the limiting groove 401. A limiting plate 404 in an I-shape for controlling the position of the I-block 303 is fixedly installed on one side of each I-block 303. One side of each limiting plate 404 is in contact with the clamping assembly 2. Both ends of the top of each limiting plate 404 are in contact with the side of the adjacent stop bar 403 near the clamping assembly 2.

[0025] The stop bar 403 can restrict the position of the limiting plate 404 to prevent the I-shaped block 303 from sliding during processing, thereby preventing the fixture assembly 2 from shifting; at the same time, the limiting plate 404 fits against the fixture assembly 2, which can further enhance the stability of the fixture assembly 2 after installation.

[0026] Each limiting groove 401 is equipped with two first springs 5 ​​inside, and the two ends of each first spring 5 are fixedly installed to the adjacent push plate 402 and the inner wall of the limiting groove 401 respectively.

[0027] The first spring 5 can generate an elastic thrust on the push plate 402, so that the stop bar 403 always remains in contact with the limiting plate 404, ensuring the continuity of the limiting effect.

[0028] Each first sliding groove 301 is provided with a limiting rod 6 inside, each I-shaped block 303 is slidably sleeved on the adjacent limiting rod 6, and each limiting rod 6 is sleeved with a second spring 7. The two ends of each second spring 7 abut against the adjacent limiting plate 404 and the inner wall of the first sliding groove 301, respectively.

[0029] The limiting rod 6 can guide the sliding direction of the I-shaped block 303, preventing the I-shaped block 303 from shifting or getting stuck in the first sliding groove 301, ensuring smooth sliding of the I-shaped block 303, and further improving the ease of assembly and disassembly of the fixture assembly 2.

[0030] Each limiting groove 401 has a concave limiting strip 8 fixedly installed on its top, and each limiting plate 404 has a hook plate 9 rotatably installed on one side. One end of each hook plate 9 is concave, and each hook plate 9 is adapted to the adjacent limiting strip 8.

[0031] The movable limiting plate 404 pulls the I-shaped block 303 out of the second sliding groove 302, and then rotates the hook plate 9 to engage with the limiting strip 8, which can fix the limiting plate 404 a second time and facilitate the replacement of the clamp assembly 2.

[0032] The implementation principle of a positioning fixture for centrifugal nozzle processing in this application embodiment is as follows: First, the operator places the fixture assembly 2 to be installed on the top of the base plate 1, so that the second sliding groove 302 at the bottom of the fixture assembly 2 is aligned with the opening of the first sliding groove 301 on the base plate 1. This process is the initial positioning to ensure smooth subsequent parts fitting.

[0033] First, press down the stop bar 403, causing the push plate 402 to press down the first spring 5, putting the first spring 5 in a compressed state. At this time, the limiting plate 404 is in the position of compressing the second spring 7. Then, push the limiting plate 404 towards the clamp assembly 2. The limiting plate 404 drives the I-shaped block 303, which is fixedly connected to it, to slide along the limiting rod 6 in the first sliding groove 301. Until the top of the I-shaped block 303 is completely slid into the second sliding groove 302, at this time, one side of the limiting plate 404 is tightly fitted with the clamp assembly 2, completing the initial cooperation between the fixing component and the clamp assembly 2.

[0034] When the limiting plate 404 is in contact with the fixture assembly 2, the stop bar 403 is released, the first spring 5 unfolds and the processing push plate 402 is lifted. At this time, the stop bar 403 is just in contact with the top two ends of the limiting plate 404, realizing the initial limiting of the limiting plate 404 and preventing the I-shaped block 303 from sliding in the opposite direction. The entire installation process of the fixture assembly 2 is completed, and the positioning processing of the centrifugal nozzle can begin.

[0035] When the fixture needs to be disassembled and replaced, first, press down the stop bar 403 to compress the first spring 5 with the push plate 402. The operator slides the limiting plate 404 to one side of the limiting bar 8, and then rotates the hook plate 9 to engage with the limiting bar 8. The second spring 7 will be compressed. At this time, the I-shaped block 303 has moved out of the second sliding groove 302, so the entire fixture assembly 2 can be removed for replacement.

[0036] After the clamp assembly 2 is replaced, the hook plate 9 is rotated in the opposite direction to disengage the hook plate 9 from the limiting strip 8. After the limiting plate 404 is released, the first spring 5 and the second spring 7 release their elastic potential energy, which pushes the push plate 402 and the limiting plate 404 back to their initial positions, respectively, to prepare for the next installation.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
