Description

Technical Field

[0001] This utility model relates to the field of shell clamping and positioning technology, and in particular to a clamping fixture for shells. Background Technology

[0002] In modern manufacturing, the application scenarios of housing parts are constantly expanding, from small electronic component housings to large equipment housings. Their specifications and shapes vary significantly, and the proportion of complex structures such as curved surfaces, steps, and irregular holes continues to rise, which poses a greater challenge to the adaptability of clamping fixtures.

[0003] Most current mainstream housing clamping fixtures adopt a fixed structure, with core positioning components and clamping modules customized for specific housing models, leaving almost no room for adjustment. For example, a fixture designed for a certain type of housing has a positioning pin layout and clamping block stroke that perfectly match the structure of that housing. However, when switching to a housing in the same series but with slight differences in size, the original positioning pins may not work properly due to compatibility issues, and the clamping blocks may also have difficulty fitting against the workpiece surface, necessitating a complete replacement of the fixture to continue production.

[0004] When the shell undergoes localized structural adjustments for functional optimization, such as adding reinforcing ribs or changing interface positions, existing fixtures often become unusable due to insufficient compatibility, further increasing production costs. Therefore, breaking free from the constraints of fixed structures and developing universal clamping fixtures with flexible adjustment capabilities has become an important direction for improving the flexibility and economy of shell processing. Utility Model Content

[0005] The purpose of this invention is to provide a clamping fixture for housings to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A clamping fixture for a housing, comprising:

[0008] The base has a first through-hole on the top left side and a second through-hole on the top right side.

[0009] A first round rod, the bottom end of which is fixedly installed in a first mounting hole, and a first spring is sleeved on the middle section of the first round rod;

[0010] The second round rod, and multiple second round rods are provided, with the bottom ends of the multiple second round rods fixedly installed on the top of the base;

[0011] The first mounting block has a first clearance hole that extends vertically through its top end, and the top end of the first round rod passes through the first clearance hole.

[0012] A fixing module is fixedly installed in the second mounting hole, and the fixing module is used to fix the housing.

[0013] By adopting the above technical solution, the first round rod cooperates with the first mounting hole to achieve positioning and installation, the first spring can provide elastic support for the first mounting block, multiple second round rods can limit the bottom of the housing at multiple points, and the fixing module can cooperate with the first mounting block and other components to achieve reliable fixing of the housing, meet the housing clamping requirements, and limit different housings through the fixing module and the first spring.

[0014] In a further embodiment, a slide rail is fixedly mounted on the top of the first mounting block, and a second mounting block is slidably mounted on the top of the slide rail. A limit block is fixedly mounted on the top of the first mounting block, and the limit block is located on the left side of the slide rail. One end of a second spring is fixedly mounted on the left end of the second mounting block, and the other end of the second spring is fixedly mounted to the limit block. A rounded corner is provided on the right end of the second mounting block.

[0015] By adopting the above technical solution, the second mounting block can slide flexibly along the slide rail. Under the elastic action of the second spring, it can adaptively abut against the side of the housing. At the same time, the rounded corner design at the right end of the second mounting block can prevent the housing from being bumped when it is put in, making it easier for the housing to be placed in place smoothly, and effectively improving the convenience of housing clamping.

[0016] In a further embodiment, the fixing module includes:

[0017] A cylinder, comprising a fixed end and a movable end, wherein the fixed end of the cylinder is fixedly mounted on the top of a base;

[0018] The cylinder has a fixed block, which is fixedly installed on the top of the movable end of the cylinder. An elastic pad is provided on the side of the fixed block that contacts the housing. The elastic pad is used to buffer the pressure of the fixed block on the housing. The fixed block is used to limit the movement of the housing.

[0019] By adopting the above technical solution, the fixed end of the cylinder is firmly connected to the base, and the movable end can drive the fixed block to reciprocate, thereby quickly completing the clamping and releasing operation of the housing; the elastic pad on the fixed block can effectively buffer the pressure during clamping and prevent damage to the surface of the housing due to squeezing, thus ensuring that the housing is firmly fixed and playing a good protective role.

[0020] In a further embodiment, a nut is rotatably mounted on the top end of the first round rod, the outer circumferential surface of the top end of the first round rod is provided with an external thread, the inner circumferential surface of the nut is provided with an internal thread adapted to the external thread, the nut is threadedly connected to the first round rod, and the nut is used to adjust the height of the first mounting block.

[0021] By adopting the above technical solution, the height position of the first mounting block on the first round rod can be adjusted by rotating the nut by utilizing the matching fit between the external thread at the top of the first round rod and the internal thread of the nut, thereby adapting to the clamping requirements of housings of different specifications and sizes, and greatly improving the versatility of the fixture.

[0022] In a further embodiment, the top of the second round rod is provided with anti-slip texture, and the second round rod is used to support the housing.

[0023] By adopting the above technical solution, the second round rod can provide stable support for the housing, and the anti-slip texture on its top can increase the friction with the bottom of the housing, effectively preventing the housing from sliding or shifting during clamping or subsequent processing, and further improving the stability of the housing placement.

[0024] In a further embodiment, the first round rod and the first mounting hole are clearance-fitted, and the axis of the first round rod is collinear with the axis of the first mounting hole.

[0025] By adopting the above technical solution, the cylinder is activated, causing the fixed block to move upward, leaving enough space for the housing. Then, the second mounting block is moved to the left, compressing the second spring, which facilitates the installation of the housing. The bottom end of the housing is placed on top of the base, and then one side of the housing is restricted by the second round rod. The cylinder is activated, causing the fixed block to move downward, thus fixing and limiting the housing. The second mounting block is released, and under the action of the second spring, it restricts the housing. The height of the first mounting block can be adjusted by rotating the nut to accommodate different housing shapes by compressing the first spring.

[0026] In summary, this utility model has the following beneficial effects:

[0027] 1. After the cylinder is activated, the moving end of the cylinder rises smoothly, causing the fixed block to move upwards synchronously. At this time, a sufficient gap is formed between the fixed block and the top of the base, providing ample operating space for the installation of the housing. During operation, attention should be paid to the cylinder pressure adjustment to ensure that the fixed block moves at a uniform speed and to avoid damage to components due to impact. Then, push the second mounting block to the left, allowing it to slide horizontally along the slide rail. During this process, the second spring is compressed, generating elastic potential energy, which widens the clamping inlet width, making it easier for the operator to accurately place the housing into the designated position.

[0028] When the bottom of the housing is placed stably on top of the base, the anti-slip texture at the tip of the second round rod immediately adheres to the housing surface, using friction to create initial lateral restraint on one side of the housing, effectively preventing lateral slippage during placement. After the housing position is calibrated, the cylinder reversing valve is activated, and the moving end drives the fixed block to slowly move downwards. The elastic pad on the inner side of the fixed block first contacts the housing surface, and then the downward force gradually increases. This achieves longitudinal compression through a rigid structure while using elastic buffering to prevent indentations or deformation on the housing surface.

[0029] After the second mounting block is released, the compressed second spring quickly releases its elastic force, pushing the second mounting block to reset to the right along the slide rail. The rounded corner design at its right end can avoid hard collision with the edge of the housing. Finally, it completes the lateral clamping from the other side, forming a three-dimensional limiting structure together with the second round rod and the fixing block, ensuring that the housing does not move during the processing.

[0030] To accommodate irregularly shaped or differently sized housings, the height of the first mounting block can be adjusted by rotating the nut: Turning the nut clockwise causes it to move downwards along the external thread of the first rod, compressing the first spring and causing it to deform, thus moving the first mounting block downwards simultaneously; turning it counterclockwise causes the first spring to rebound, raising the mounting block. This adjustment method utilizes the elastic potential energy of the spring to achieve fine-tuning of the height, precisely matching the curved or stepped structure of the housing, significantly improving the fixture's adaptability to diverse housings, while ensuring stability and ease of operation during clamping.

[0036] Example 1:

[0037] like Figures 1-2 As shown, a clamping fixture for a housing includes a base 1, with a first through-hole on the left side of the top of the base 1 and a second through-hole on the right side of the top of the base 1; a first round rod 2, the bottom end of which is fixedly installed in the first through-hole, and a first spring 3 sleeved on the middle section of the first round rod 2; multiple second round rods 4, the bottom ends of which are fixedly installed on the top of the base 1; a first mounting block 5, with a first clearance hole on the top of the first mounting block 5, through which the top of the first round rod 2 passes; and a fixing module 6, which is fixedly installed in the second through-hole and is used to fix the housing.

[0038] A slide rail 7 is fixedly installed on the top of the first mounting block 5, and a second mounting block 8 is slidably installed on the top of the slide rail 7. A limit block 9 is fixedly installed on the top of the first mounting block 5, and the limit block 9 is located on the left side of the slide rail 7. One end of a second spring 11 is fixedly installed on the left end of the second mounting block 8, and the other end of the second spring 11 is fixedly installed with the limit block 9. A rounded corner is provided on the right end of the second mounting block 8.

[0039] The fixing module 6 includes a cylinder 61, which has a fixed end and a movable end. The fixed end of the cylinder 61 is fixedly installed on the top of the base 1. The fixing block 62 is fixedly installed on the top of the movable end of the cylinder 61. An elastic pad is provided on the side surface of the fixing block 62 that contacts the housing. The elastic pad is used to buffer the pressure of the fixing block 62 on the housing. The fixing block 62 is used to limit the movement of the housing.

[0040] A nut 10 is rotatably mounted on the top end of the first round rod 2. The outer circumferential surface of the top end of the first round rod 2 is provided with an external thread, and the inner circumferential surface of the nut 10 is provided with an internal thread that matches the external thread. The nut 10 is threadedly connected to the first round rod 2 and is used to adjust the height of the first mounting block 5.

[0041] The top of the second round rod 4 is provided with anti-slip texture. The second round rod 4 is used to support the housing. The first round rod 2 and the first mounting hole are clearance fit. The axis of the first round rod 2 is collinear with the axis of the first mounting hole.

[0042] Specific implementation process: After the cylinder is activated, the moving end of the drive cylinder 61 rises smoothly, causing the fixed block 62 to move upward synchronously. At this time, the fixed block 62 forms a sufficient gap with the top of the base 1, providing ample operating space for the installation of the housing. During operation, attention should be paid to the cylinder pressure adjustment to ensure that the moving speed of the fixed block 62 is uniform and to avoid component damage due to impact. At this time, the second mounting block 8 is pushed to the left, causing it to slide horizontally along the slide rail 7. During the process, the second spring 11 is compressed and generates elastic potential energy, thereby expanding the width of the clamping entrance, making it easier for the operator to accurately place the housing into the designated position.

[0043] When the bottom of the housing is placed stably on top of the base 1, the anti-slip texture at the top of the second round rod 4 immediately adheres to the housing surface, forming an initial lateral limit on one side of the housing through friction, effectively preventing the housing from sliding or shifting during placement. After the housing position is calibrated, the reversing valve of cylinder 61 is activated, and the moving end drives the fixed block 62 to move slowly downward. The elastic pad on the inner side of the fixed block 62 first contacts the housing surface, and then the downward force gradually increases. This achieves longitudinal compression through a rigid structure, while using elastic buffering to avoid indentations or deformation on the housing surface.

[0044] After the second mounting block 8 is released, the compressed second spring 11 quickly releases its elastic force, pushing the second mounting block 8 to reset to the right along the slide rail 7. The rounded corner design at its right end can avoid hard collision with the edge of the housing. Finally, it completes the lateral clamping from the other side, forming a three-dimensional limiting structure together with the second round rod 4 and the fixing block 62, ensuring that the housing does not move during the processing.

[0045] To accommodate irregularly shaped or differently sized housings, the height of the first mounting block 5 can be adjusted by rotating the nut 10: when the nut 10 is rotated clockwise, it moves downward along the external thread of the first round rod 2, compressing the first spring 3 and causing it to deform, thus moving the first mounting block 5 downward simultaneously; when rotated counterclockwise, the spring rebounds, and the mounting block rises accordingly. This adjustment method utilizes the elastic potential energy of the first spring 3 to achieve fine-tuning of the height, precisely matching the curved surface or stepped structure of the housing, significantly improving the fixture's adaptability to diverse housings, while ensuring stability and ease of operation during clamping.
