Description

Technical Field

[0001] This utility model relates to the field of connector housing processing tools, and in particular to a special fixture for grinding regular polygonal connector housings. Background Technology

[0002] Connector housings are used to house electronic components that include connectors, and are fitted over the electronic components. Connector housings come in various shapes, but those with a regular polygonal cross-section are widely used.

[0003] Some applications have high requirements for the outer wall of the connector housing, often necessitating grinding to meet these requirements. However, existing technologies typically use conventional clamping fixtures to hold polygonal connector housings. For example, a four-jaw chuck is commonly used for square connector housings. While this method meets the clamping requirements, it results in low clamping efficiency for mass production.

[0004] Therefore, existing polygonal connector housing clamps suffer from technical problems such as inconvenient operation and low clamping efficiency. Summary of the Invention

[0005] This utility model provides a special fixture for grinding regular polygonal connector housings, which solves the technical problems of inconvenient operation and low clamping efficiency of existing regular polygonal connector housing fixtures.

The support assembly includes a support plate, with each side of the connector housing corresponding to an independent support plate, and the support plate is slidably connected to the upright plate. And a drive assembly, the drive assembly being disposed on the base, the drive assembly driving all the support plates of the support assembly to move away from each other and clamp the connector housing; The support plate has a protrusion on the side away from the connector housing, and the protrusion has an inclined surface. All the inclined surfaces of the support plates form a frustum-shaped driving cavity. The support assembly includes a support shaft slidably connected to the upright plate. The support shaft has a driving part that cooperates with the driving cavity. The cross-sectional shape of the driving part is frustum-shaped. The driving part cooperates with the driving cavity and pushes the support plates away from each other through the protrusion. There are multiple drive units, and each drive unit is coupled to an independent drive cavity.

[0007] Preferably, the upright plate is provided with a guide groove, and the support plate is provided with a guide rail that cooperates with the guide groove, and the guide rail and the support plate are an integral structure.

[0008] Preferably, the guide rail includes a guide portion and a connecting portion. The guide portion is disposed on the support plate through the connecting portion. The width of the guide portion is greater than the width of the connecting portion. The guide groove includes a first portion that cooperates with the guide portion and a second portion that cooperates with the connecting portion. The first portion and the second portion communicate with each other.

[0009] Preferably, the guide groove is provided with a first elastic element that pushes the support plates to bring all the support plates closer to each other, and each guide groove is provided with an independent first elastic element.

[0010] Preferably, the first elastic element is a spring, one end of which is fixed to the side wall of the guide groove, and the other end of which is fixed to the guide rail.

[0011] Preferably, the upright plate is provided with a guide shaft for guiding the support shaft, and the support shaft is provided with a guide hole that mates with the guide shaft, the guide hole penetrating both end faces of the support shaft.

[0012] Preferably, the guide shaft is provided with a second elastic element, which pushes the support shaft to displace the driving part relative to the driving cavity and causes the support plates to tend to move closer to each other.

[0013] Preferably, the second elastic element is a spring, which is sleeved on the guide shaft. One end of the second elastic element contacts the upright plate, and the other end of the second elastic element contacts the support shaft.

[0015] Preferably, the push plate is provided with a push block extending into the drive cavity, the push block and the push plate are integrally formed, the push plate is provided with a slider, and the base is provided with a groove that cooperates with the slider.

[0016] Compared with the prior art, the present invention has the following advantages: By setting multiple independent support plates that correspond one-to-one with each side of the connector housing, the fixture can be used to clamp the connector housing evenly and stably, reducing vibration and offset during the grinding process, thereby improving grinding accuracy and surface quality.

[0017] By sliding the support plates to the upright plate and driving all the support plates to move away from each other via a drive assembly, the fixture can quickly and accurately clamp the connector housing, greatly improving clamping efficiency. At the same time, the simultaneous movement of all support plates also ensures uniform and stable clamping.

[0018] By providing a protrusion on the side of the support plate away from the connector housing, and making the inclined surfaces of all the support plates form a frustum-shaped drive cavity, an effective drive surface is provided for the drive assembly. This allows the drive assembly to push the support plates away from each other through the protrusion, thereby achieving a clamping action. The frustum-shaped drive cavity design also ensures the smoothness and accuracy of the drive.

[0019] By setting a support shaft that slides onto the upright plate, and a frustum-shaped drive unit that mates with the drive cavity on the support shaft, the configuration of the support shaft and drive unit allows the drive assembly to precisely control the movement of the support plate, ensuring the clamping force and accuracy. Simultaneously, the mating of the frustum-shaped drive unit with the frustum-shaped drive cavity also improves the efficiency and stability of the drive.

[0020] By incorporating multiple drive units, each engaging with an independent drive cavity, the adaptability and stability of the fixture are enhanced. Even if one drive unit or drive cavity fails, the others can still function normally, ensuring the reliability and durability of the fixture. Simultaneously, the coordination of multiple drive units and drive cavities also improves the clamping force and uniformity. Attached Figure Description

[0031] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0032] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0033] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0034] Reference Figures 1 to 6 As shown, a special fixture for grinding a regular polygonal connector housing includes a base 1; An upright plate 11 is disposed on the base 1; Support component 2 is disposed on the upright plate 11 and inserted into the connector housing. The support component 2 includes a support plate 21, and each side of the connector housing corresponds to an independent support plate 21. The support plate 21 is slidably connected to the upright plate 11. And drive assembly 3, the drive assembly 3 is disposed on the base 1, the drive assembly 3 drives all the support plates 21 of the support assembly 2 to move away from each other and clamp the connector housing; The support plate 21 has a protrusion 211 on the side away from the connector housing. The protrusion 211 has a slope 212. All the slopes 212 of the support plates 21 form a frustum-shaped driving cavity. The support assembly 2 includes a support shaft slidably connected to the upright plate 11. The support shaft has a driving part 221 that cooperates with the driving cavity. The cross-sectional shape of the driving part 221 is frustum-shaped. The driving part 221 cooperates with the driving cavity and pushes the support plates 21 away from each other through the protrusion 211. There are multiple drive units 221, and each drive unit 221 is coupled with an independent drive cavity.

[0035] Specifically, because the drive unit 221 is frustoconical and the drive cavity is also frustoconical, the support plate 21 can be positioned in different locations when the drive unit 221 contacts different parts of the drive cavity. For example, when the small end of the drive cavity contacts the large end of the drive unit 221, the distance between the support plates 21 is the largest, and the connecting housing can be clamped using the supporting force. When the small end of the drive cavity contacts the small end of the drive unit 221, the distance between the support plates 21 is the smallest, no clamping force is provided, and the connector housing can be easily removed.

[0036] Understandably, since there is a certain gap between two adjacent support plates 21 when the support plate 21 clamps the connector housing, and this gap is located at the corner of the connector housing, the gap between two adjacent support plates 21 does not affect the clamping of the connector housing by the fixture. In addition, since the connector housing does not bear a large force during the grinding process, the existence of this gap does not affect the clamping function of the fixture.

[0037] Reference Figures 1 to 6 As shown, in some embodiments, the upright plate 11 is provided with a guide groove 111, and the support plate 21 is provided with a guide rail 213 that cooperates with the guide groove 111. The guide rail 213 and the support plate 21 are an integral structure.

[0038] In some embodiments, the guide rail 213 includes a guide portion and a connecting portion. The guide portion is disposed on the support plate 21 through the connecting portion. The width of the guide portion is greater than the width of the connecting portion. The guide groove 111 includes a first portion that cooperates with the guide portion and a second portion that cooperates with the connecting portion. The first portion and the second portion communicate with each other.

[0039] In some embodiments, the cross-sectional shape of the guide rail 213 may also be trapezoidal, as long as the guide rail 213 cannot move in the direction of approaching or moving away from the vertical plate 11. Therefore, the cross-sectional shape of the guide rail 213 is not limited and can be reasonably determined as needed.

[0040] In some embodiments, a first elastic element 12 is provided in the guide groove 111 to push the support plate 21 so that all the support plates 21 are close to each other, and an independent first elastic element 12 is provided in each guide groove 111.

[0041] In practice, even without elastic elements, when the small end of the drive unit 221 corresponds to the large end of the drive cavity, since the drive unit 221 does not provide a support function, one or more of its support plates 21 will be displaced under the action of gravity and will disengage from the connector housing. The connector housing can still be clamped or removed normally.

[0042] Reference Figures 1 to 6 As shown, in some embodiments, the first elastic element 12 is a spring, one end of which is fixed to the side wall of the guide groove 111, and the other end of which is fixed to the guide rail 213.

[0043] In some embodiments, the upright plate 11 is provided with a guide shaft 13 for guiding the support shaft, and the support shaft is provided with a guide hole that cooperates with the guide shaft 13, the guide hole penetrating through the two end faces of the support shaft.

[0044] In some embodiments, the guide shaft 13 is provided with a second elastic element 131, which pushes the support shaft to displace the drive portion 221 relative to the drive cavity and causes the support plates 21 to tend to move closer to each other.

[0045] In some embodiments, the second elastic element 131 is a spring, the second elastic element 131 is sleeved on the guide shaft 13, one end of the second elastic element 131 contacts the upright plate 11, and the other end of the second elastic element 131 contacts the support shaft.

[0046] In some embodiments, the guide shaft 13 may be an integral structure with the upright plate 11.

[0047] In some embodiments, the drive assembly 3 includes a push plate 31 that pushes the support shaft to cause the drive part 221 to push the support plate 21 away from each other. The push plate 31 is slidably connected to the base 1. The base 1 is provided with a lead screw 32 for driving the push plate 31. The push plate 31 is provided with a screw hole that cooperates with the lead screw 32.

[0048] In some embodiments, the push plate 31 is provided with a push block 311 extending into the drive cavity. The push block 311 and the push plate 31 are integrally formed. The push plate 31 is provided with a slider, and the base 1 is provided with a groove 33 that cooperates with the slider.

[0049] In some embodiments, the slider and push plate 31 can be an integral structure.

[0050] Reference Figures 1 to 6 As shown, in some embodiments, when the support shaft is a hollow structure, the push block 311 can also be provided with an extension column, which can extend into the support shaft to improve the stability of the support shaft.

[0051] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0052] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.
