Description

Technical Field

[0001] The utility model relates to the technical field of filter housings, and particularly relates to a numerical control machining fixture for a filter housing. Background Technique

[0002] A filter housing generally refers to a casing or casing structure for installing filter elements. This kind of casing is usually used to protect the internal elements of the filter from the external environment and ensure its normal operation. The filter housing is usually made of metal, plastic or other durable materials, and has appropriate sealing performance and corrosion resistance.

[0003] In the existing related technologies, there are often the following defects: When the filter housing is produced, it needs to be further processed using a numerical control machine tool, and a fixture is required for clamping during processing. When the existing fixture clamps and processes the filter housing, the debris generated during processing is likely to accumulate on the surface of the fixture. The accumulation of debris may cause the fixture to fix the filter housing unstably, posing a risk of insecure clamping and affecting the processing safety.

[0004] Therefore, the utility model provides a numerical control machining fixture for a filter housing. Content of the Utility Model

[0007] The effect achieved by the above components is: By setting the collection structure, it is convenient to collect the debris generated during the processing of the filter housing using the fixture, thereby avoiding the accumulation of debris on the surface of the fixture and affecting the clamping stability of the filter housing, and further improving the clamping stability of the filter housing.

[0008] Preferably, a spring is sleeved on the arc surface of the pin, and both ends of the spring are fixedly connected to the pin and the bracket respectively.

[0009] The effects achieved by the above components are as follows: The bolt will be inserted into the round hole by the force of the spring contraction.

[0016] Preferably, a round rod slidably penetrates through the surfaces of the two limit blocks, and both ends of the round rod are fixedly connected to the rectangular box.

[0017] The effects achieved by the above components are as follows: When the limit block moves, it will slide along the surface of the round rod. The round rod restricts the movement path of the limit block, thereby preventing the limit block from rotating during movement, and further facilitating the installation of the fixture on the numerically controlled machine tool.

[0018] In summary:

Detailed Embodiment

[0027] Refer to Figure 1As shown in the figure, the utility model provides a technical solution: a numerical control machining fixture for a filter housing, including a base 1. Two hydraulic telescopic rods 2 are installed on the surface of the base 1. The output ends of the hydraulic telescopic rods 2 are fixedly connected with clamping plates 3. A collection structure 4 is arranged on the surface of the base 1. By setting the collection structure 4, it is convenient to collect the chips generated during the machining of the filter housing by using the fixture, thereby avoiding the accumulation of chips on the surface of the fixture and affecting the clamping stability of the filter housing, and further improving the clamping stability of the filter housing. Adjusting structures 5 are arranged on both sides of the base 1. By setting the adjusting structures 5, it is convenient to adjust the distance between the two limit blocks 53, so that the fixture can be installed on numerically controlled machine tools of different sizes, and further improve the practicability of the fixture.

[0028] Next, specifically describe the specific settings and functions of its collection structure 4 and adjusting structure 5.

[0029] Refer to Figure 2 and Figure 3 and Figure 4 As shown in the figure, in this implementation scheme: the collection structure 4 includes a rectangular groove 401, which is opened on the surface of the base 1. A collection box 402 is slidably inserted into the inner wall of the rectangular groove 401. A rectangular plate 403 is fixedly connected to the side of the collection box 402 away from the base 1. A filter screen 404 is fixedly connected to the surface of the base 1. Support brackets 405 are fixedly connected to both sides of the base 1. A pin 406 is slidably penetrated through the surface of the support bracket 405. Limit plates 407 are fixedly connected to both sides of the rectangular plate 403. Circular holes 408 are opened on the surface of the limit plates 407. The size of the pin 406 is adapted to the size of the circular hole 408. A spring 409 is sleeved on the arc surface of the pin 406. The two ends of the spring 409 are respectively fixedly connected to the pin 406 and the support bracket 405. The pin 406 will be inserted into the circular hole 408 by the force of the contraction of the spring 409. The spring 409 improves the stability of the pin 406 inserted into the circular hole 408 and avoids the pin 406 slipping out of the circular hole 408 due to shaking. A plurality of fixing rods 410 are fixedly connected to the inner wall of the rectangular groove 401. Cylinders 411 are sleeved on the arc surfaces of the plurality of fixing rods 410. The collection box 402 will slide along the surface of the cylinder 411 when it moves. The cylinder 411 will rotate on the surface of the fixing rod 410 by the force of the movement of the collection box 402. The cylinder 411 reduces the friction when the collection box 402 moves in the rectangular groove 401, thus facilitating the movement of the collection box 402. A pull rod 412 is fixedly connected to the side of the rectangular plate 403 away from the collection box 402. The cross-section of the pull rod 412 is in the shape of a "U". The movement of the pull rod 412 will drive the movement of the rectangular plate 403. The pull rod 412 facilitates pulling the position of the rectangular plate 403, and further facilitates pulling the position of the collection box 402.

[0030] Refer to Figure 5As shown in the figure, specifically, the adjusting structure 5 includes a rectangular box 51. The rectangular box 51 is fixedly connected to the surface of the base 1. A bidirectional screw rod 52 is rotatably connected to the inner wall of the rectangular box 51. Two limit blocks 53 are threadedly connected to the surface of the bidirectional screw rod 52. A limit hole 54 is formed on the surface of the limit block 53. A round rod 55 slidably penetrates through the surfaces of the two limit blocks 53. Both ends of the round rod 55 are fixedly connected to the rectangular box 51. When the limit block 53 moves, it will slide along the surface of the round rod 55. The round rod 55 restricts the moving path of the limit block 53, thereby avoiding the situation that the limit block 53 rotates when moving, and further facilitating the installation of the fixture on the numerical control machine tool.

[0031] Working principle: When it is necessary to use the fixture to numerically control process the filter housing, first place the filter housing on the surface of the base 1, and then drive the two hydraulic expansion rods 2. The hydraulic expansion rods 2 will drive the clamping plates 3 to squeeze the filter housing, thereby clamping the filter housing, and then process the filter housing. The debris generated during processing will fall onto the surface of the filter screen 404, and the debris will pass through the filter screen 404 and fall into the collection box 402. When the filter housing is processed, pull the bolt 406. The bolt 406 will move within the bracket 405 and gradually disengage from the round hole 408. When the bolt 406 moves, it will stretch the spring 409. When the bolt 406 disengages from the round hole 408, at this time the spring 409 is in a stretched state. Then pull the pull rod 412. The movement of the pull rod 412 will drive the rectangular plate 403 to move. The movement of the rectangular plate 403 will drive the collection box 402 to slide within the rectangular groove 401. The movement of the collection box 402 will slide along the surface of the cylinder 411. The cylinder 411 will rotate on the surface of the fixed rod 410 by virtue of the force of the movement of the collection box 402. The cylinder 411 reduces the friction when the collection box 402 moves within the rectangular groove 401, thereby facilitating the movement of the collection box 402. When the collection box 402 disengages from the rectangular groove 401, it is convenient to take out the debris in the collection box 402. Then place the collection box 402 back into the rectangular groove 401 and release the bolt 406. The bolt 406 will insert into the round hole 408 by virtue of the contracting force of the spring 409. The bolt 406 restricts the position of the limit plate 407, and further restricts the position of the collection box 402.

[0032] When it is necessary to install the fixture on the numerical control machine tool, first rotate the bidirectional screw rod 52. The rotation of the bidirectional screw rod 52 will drive the two limit blocks 53 to move towards each other by means of the thread. When the limit block 53 moves, it will slide along the surface of the round rod 55. The round rod 55 restricts the moving path of the limit block 53, thereby avoiding the situation that the limit block 53 rotates when moving, and further facilitating the installation of the fixture on the numerical control machine tool. When the limit block 53 moves to an appropriate position, pass the bolt through the limit hole 54 and screw it onto the surface of the machine tool, thereby installing the fixture on the numerical control machine tool.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific circumstances.
