In the existing coating fixture for spherical parts, the spherical part is clamped between two opposite columnar fixtures, and the two columnar fixtures only position the spherical part in the relative direction of the two columnar fixtures, while the spherical part is installed During the clamping process, it is very easy to move in other directions than the above-mentioned relative directions, which makes the clamping of the spherical parts more difficult and less efficient.

However, in the spherical part coating fixture of the present application, the spherical part is supported on the base, and the spherical part is clamped on the side by using the rib and the mounting surface. It is only necessary to place the spherical part in the accommodating cavity and adjust the positioning. The distance between the sleeve and the supporting surface in the depth direction of the accommodating cavity can be used to complete the precise positioning and assembly of the spherical parts, which is easy to install and has high assembly efficiency.

The sphere part coating jig and the sphere part coating clamping mechanism of the embodiment of the present application will be described below with reference to the accompanying drawings. It should be noted that the spherical parts in this application include but are not limited to parts with a perfect spherical outer contour, such as bearing balls, etc. The spherical parts in this application can also be parts with roughly spherical outer contours, such as ellipsoidal spheres , polygonal sphere, etc. In this application, the spherical part is taken as an example for illustration, and the case of other types of spherical parts is similar, and will not be repeated here.

Figure 1 is a schematic structural view of the spherical part coating jig provided by the embodiment of the present application, Figure 2 is a schematic diagram of the exploded structure of the spherical part coating jig provided by the embodiment of the present application, and Figure 3 is a cross-sectional view of the spherical part coating jig provided by the embodiment of the present application .

Referring to FIG. 1 , FIG. 2 , and FIG. 3 , the spherical part coating fixture 100 of this embodiment includes a housing plate 10 , an adjustment member 20 disposed on the housing disc 10 , and a positioning sleeve 30 disposed on the adjustment member 20 .

Wherein, the accommodation tray 10 includes a base 11 having a supporting surface 13 and an annular rib 12 arranged on the base 11, the supporting surface 13 and the annular rib 12 define a space for accommodating the spherical part 50. Accommodating chamber 14. The positioning sleeve 30 has a positioning surface 31 opposite to the inner surface of the annular rib 12 , the positioning surface 31 is configured as a conical surface, and the small diameter end of the positioning surface 31 is disposed close to the support surface 13 . The adjusting member 20 is used to drive the positioning sleeve 30 to move towards the support surface 13 to press the spherical part 50 into the accommodating cavity 14 by means of the positioning surface 31 , that is, to press against the support surface 13 and the annular rib 12 .

In the above solution, the housing plate 10 includes a base 11 and an annular rib 12, both of which can jointly enclose the housing chamber 14, and the spherical part 50 can be placed in the housing chamber 14 relatively easily, and It is blocked by the ring-shaped rib 12 and is not easy to roll out of the accommodating cavity 14, which can realize the pre-positioning of the spherical part 50 at the initial stage of installation. In addition, the conical positioning surface 31 on the positioning sleeve 30 is arranged opposite to the ring-shaped rib 12. When the adjustment member 20 is operated to drive the positioning sleeve 30 to move toward the support surface 13, the positioning surface 31 and the ring-shaped rib will The distance between the inner surface of the side 12 and the ring-shaped rib 12 decreases continuously until the spherical part 50 is clamped between the positioning surface 31 and the ring-shaped rib 12 . During installation, it is only necessary to place the spherical part 50 in the accommodating cavity 14 and adjust the distance between the positioning sleeve 30 and the supporting surface 13 in the depth direction S of the accommodating cavity 14 to complete the installation. Compared with the prior art where the relative position of the spherical part 50 and the cylindrical fixture must be guaranteed, the installation is relatively simple and the clamping efficiency is also high. And because the positioning surface 31 is set as a tapered surface, this also reduces the overall tolerance requirement of the fixture and reduces the manufacturing cost of the fixture.

In addition, the supporting surface 13 of the base 11, the annular rib 12 and the positioning sleeve 30 respectively position the spherical part 50 at the bottom and two opposite sides of the spherical part 50, not only the contact area with the spherical part 50 is small, At the same time, the clamping in three directions is more reliable.

As shown in Fig. 3, the annular rib 12 can surround the outer edge of the base 11, wherein the top surface of the base 11 can be formed as a support surface 13, such that the support surface 13 and the rib 12 are radially inner. The side surfaces jointly define an accommodating cavity 14 . The accommodating cavity here can be, for example, a cover-shaped space. When the base 11 can also be of other shapes, the annular rib 12 can also be formed on other positions of the base 11 , as long as it can jointly define the accommodating cavity 14 with the supporting surface 13 .

It should be noted that the annular shape of the rib 12 specifically means that the end of the rib 12 is closed so as to enclose the accommodating cavity 14 together with the supporting surface 13 . Exemplarily, the ring-shaped rib 12 can mean that the rib 12 is in the shape of a ring, and correspondingly, the base 11 can be formed in the shape of a cone, so that the ring-shaped rib 12 can surround the outside of the base 11 fringe all week. Certainly, the shape of the rib 12 is not limited to a ring shape, and may also be polygonal or other shapes to form a ring shape.

In the embodiment of the present application, in order to effectively clamp the spherical part 50 between the rib 12 and the positioning surface 31 of the positioning sleeve 30, the setting height of the rib 12 relative to the supporting surface 13 can be higher than the radius of the spherical part 50 .

In addition, as previously mentioned, the spherical part 50 is supported on the support surface 13 and is clamped between the positioning surface 31 and the inner side of the rib 12 . In order to facilitate the movement of the spherical part 50 to the position of the rib 12, it may be considered that the support surface 13 is set to be inclined.

Specifically, the support surface 13 may include an annular guide area 131, the guide area 131 is located on the radial inner side of the rib 12 and adjacent to the rib 12, and the setting height of the guide area 131 relative to the bottom end surface 111 of the base is determined by the guide The inner side of the region 131 gradually decreases towards the outer side. The guide area 131 mentioned here is adjacent to the rib 12 specifically means that the outer edge of the guide area 131 is continuous with the inner side of the rib 12, or it can also be directed that the outer edge of the guide area 131 is close to the inner side of the rib 12, And there is a short distance from the inner surface of the rib 12 , which is smaller than the diameter of the spherical part 50 .

Exemplarily, the guiding area 131 can be configured as a conical surface, and the small-diameter end of the guiding area 131 faces toward the center of the base 11 , and the large-diameter end of the guiding area 131 faces toward the rib 12 . In this way, when the spherical part 50 is placed in the accommodating cavity 14, it can roll to contact with the rib 12 under the action of gravity, and the automatic pre-positioning of the spherical part 50 can be completed, and the positioning process is simple and easy.

It should be noted that the extension range of the guide area 131 along the radial direction of the base can be set according to the size of the actual spherical part 50, and can only occupy a partial range of the support surface 13 as shown in FIG. 3 , or can extend to the entire support surface. 13, as long as the spherical part 50 entering the accommodation cavity 14 can automatically roll onto the rib 12.

In addition, in order to further improve the clamping efficiency, a plurality of spherical parts 50 can be placed in the accommodating cavity 14 at one time during installation. Generally, the radii of the spherical parts 50 placed at the same time are the same, therefore, it is also necessary to make the positioning surface The central axis of 31 coincides with the central axis of rib 12 . This ensures that the distance between the positioning surface 31 of the positioning sleeve 30 and the inner surface of the rib 12 is the same within the entire circumference of the rib 12 .

Referring to Fig. 2 and Fig. 3, in the embodiment of the present application, as mentioned above, in order to cooperate with the rib 12 to clamp the spherical part 50, the positioning sleeve 30 has a positioning surface 31 arranged opposite to the inner surface of the rib 12, and the positioning surface 31 is configured as a conical surface, and the small-diameter end of the conical surface is disposed close to the support surface 13 . In other words, the positioning surface 31 is a conical surface with a small diameter end facing the supporting surface 13, so that when the adjusting member 20 drives the positioning sleeve 30 to move to the supporting surface 13, the area on the positioning surface 31 opposite to the inner side of the rib 12 is aligned with the inner surface of the rib 12. The distance between the sides will become smaller and smaller to form a space for clamping the spherical part 50 .

It can be understood that the size of the positioning surface 31 in the depth direction S of the accommodating cavity 14 can be set according to actual needs, so as not to affect the coating of the spherical part 50 .

In the embodiment of the present application, referring to Fig. 2 and Fig. 3, in a possible implementation manner, the adjustment member 20 may include an adjustment rod 21 and a crimping member 22, the adjustment rod 21 is arranged on the base 11, and can be relatively The seat 11 moves along the depth direction S of the accommodating cavity 14 , and this movement may include that the adjusting rod 21 can move along two directions along the depth direction.

Exemplarily, the adjusting rod 21 can be threadedly connected with the base 11 , so that the relative position between the rod 21 and the base 11 can be adjusted only by turning the adjusting rod 21 clockwise or counterclockwise. Of course, in order to facilitate the connection of the spherical part coating jig 100 with other parts, the adjustment rod 21 can be set through the base 11, so that the part of the adjustment rod 21 passing through the base 11 can be used to connect with external parts.

The crimping member 22 can be arranged on the adjusting rod 21 and arranged opposite to the supporting surface 13 , and the positioning sleeve 30 is sleeved on the adjusting rod 21 and located between the crimping member 22 and the supporting surface 13 . When the adjusting rod 21 drives the crimping piece 22 to move towards the supporting surface 13, the crimping piece 22 pushes the positioning sleeve 30 toward the direction close to the supporting surface 13. direction of face 13.

During specific implementation, a flange portion 221 may be provided on the adjustment rod 21, and the flange portion 221 protrudes radially outward from the adjustment rod 21, and the crimping member 22 may be sleeved on the adjustment rod 21 and positioned at the and between the positioning sleeve 30. Wherein, the flange part 221 may be formed at the end of the adjustment rod 21 . Specifically, during clamping, when the adjusting rod 21 moves toward the supporting surface 13 , the flange portion 221 can drive the crimping member 22 to move toward the supporting surface 13 together.

In the embodiment of the present application, the adjustment member 20 may further include an elastic member 222, which is arranged on the adjustment rod 21, and the elastic member 222 is located between the flange portion 221 and the crimping member 22, and the elastic member 222 is used for pressing The connecting piece 22 exerts an elastic force toward the support surface 13 , so that the crimping piece 22 presses against the positioning sleeve 30 .

During installation, the adjusting rod 21 drives the flange portion 221 to move toward the supporting surface 13, and the flange portion 221 exerts elastic force on the crimping member 22 by squeezing the elastic member 222, and the crimping member 22 will press against the positioning sleeve. 30 on.

This setting, on the one hand, avoids the loosening of the clamping force or expansion and extrusion caused by high-temperature deformation, and avoids the fall-off or deformation damage of the spherical part 50 . On the other hand, the quick disassembly and assembly of the spherical part 50 can be realized through the compression of the elastic member 222, which improves the assembly efficiency.

Exemplarily, the elastic member 222 may be a spring or an elastic washer, and the elastic member 222 may be made of a high temperature resistant material.

In addition, the adjustment rod 21 can also drive the flange portion 221 to move away from the support surface 13. At this time, the elastic force exerted by the crimping member 22 on the positioning sleeve 30 through the elastic member 222 disappears or decreases, and the operator can place the positioning sleeve 30 lifts and makes the spherical part 50 disengage from the containing tray 10.

It should be noted that the two ends of the elastic member 222 may be connected to the flange portion 221 and the crimping member 22 respectively, or the two ends of the elastic member 222 may not be connected to the flange portion 221 and the crimping member 22. connect. Here, the adjusting rod 21 and the flange portion 221 can be integrally formed, such as bolts.

Continuing to refer to FIG. 2 , the positioning sleeve 30 may include a main body portion 32 and a protruding portion 33 , the main body portion 32 is sleeved on the adjustment rod 21 , the protruding portion 33 is arranged on the main body portion 32 , and extends from the main body portion 32 to the rib 12 Protruding, the protruding portion 33 forms a positioning surface 31 on the surface facing the annular rib 12 . It can be understood that the weight of the positioning sleeve 30 can be reduced as much as possible by disposing the positioning surface 31 on the protrusion 33 . In addition, the main body portion 32 and the protruding portion 33 may be formed integrally or separately.

Continuing to refer to FIG. 3 , further, in order to guide the movement of the positioning sleeve 30 , the base 11 also includes a guide sleeve 15 protruding from the support surface 13 , the guide sleeve 15 can be inserted into the positioning sleeve 30 , and The inner surface of the guide sleeve 15 is inserted into the adjustment rod 21 , and the guide sleeve 15 is located between the positioning sleeve 30 and the adjustment rod 21 to guide the movement of the guide sleeve 15 toward the supporting surface 13 . Wherein, the guide sleeve 15 and the positioning sleeve 30 , as well as the guide sleeve 15 and the adjustment rod 21 can all be in clearance fit, so as to facilitate the movement of the guide sleeve 15 relative to the adjustment rod 21 . In addition, the base 11 can be threadedly connected with the adjustment rod 21 , so that the adjustment rod 21 is convenient to move relative to the base 11 . The inner surface of the guide sleeve 15 can be provided with an internal thread that cooperates with the adjustment rod 21, so that the adjustment rod 21 can be screwed in.

In the embodiment of the present application, as mentioned above, the positioning sleeve 30 is disposed on the receiving tray 10 through the adjustment member 20 . Moreover, the adjusting member 20 is used to drive the positioning sleeve 30 to move towards the supporting surface 13 , so that the positioning surface 31 presses the spherical part 50 against the supporting surface 13 and the rib 12 . Further, the adjustment member 20 can also be used to move away from the support surface 13, so that the positioning surface 31 releases the compression of the spherical part 50, so as to facilitate the disassembly of the spherical part. FIG. 4 is a schematic structural view of the spherical part coating jig provided in the embodiment of the present application under the use state. The clamping steps of the spherical part coating jig 100 of this embodiment will be described below with reference to FIG. 1 , FIG. 3 and FIG. 4 .

Place the containing tray 10 approximately horizontally, and place a plurality of, for example, 9 spherical parts 50 into the containing cavity 14 of the containing tray 10 . In this way, the spherical part 50 rolls to abut against the inner surface of the rib 12 under the guiding action of the guiding area 131 .

Set the positioning sleeve 30 on the outside of the guide sleeve 15, and press the guide sleeve 15 downwards (towards the supporting surface 13) to complete the preliminary installation of the spherical part 50.

Screw the adjustment rod 21 in the adjustment member 20 into the guide sleeve 15 and pass through the base 11. During this process, as the adjustment rod 21 is continuously screwed in, the flange part 221 presses against the crimping member 22 through the elastic member 222 and the positioning sleeve 30 until the positioning surface 31 on the positioning sleeve 30 presses the spherical part 50 on the inner side surface of the rib 12 and the supporting surface 13, as shown in the state of FIG. 4 .

At this time, the contact between the supporting surface 13, the inner side of the rib 12, and the positioning surface 31 of the positioning sleeve 30 and the spherical part 50 is point contact, which can make the spherical part 50 have a larger exposed area, thereby improving the spherical part. 50 effective deposition area.

The process of disassembling the spherical part 50 is reversed. Specifically, the adjustment rod 21 in the adjustment member 20 is moved in a direction away from the support surface 13 , that is, the adjustment rod 21 is unscrewed from the guide sleeve 15 . During this process, as the adjusting rod 21 is continuously unscrewed, the flange portion 221 is gradually moved away from the crimping member 22, and the elastic force of the elastic member 222 on the crimping member 22 decreases or disappears. At this time, the positioning sleeve 30 is manually lifted. , or turn the part coating jig 100 upside down, then all, for example, nine spherical parts 50 in the holding tray 10 can be quickly removed in batches, which also improves the loading and unloading efficiency.

It can be understood that, since the positioning surface 31 on the positioning sleeve 30 is set as a conical surface in this embodiment, for spherical parts 50 of different sizes, it is only necessary to adjust the distance between the positioning sleeve 30 and the support surface 13 and the height of the rib 12 Size will apply.

FIG. 5 is a schematic diagram of another application scenario of the spherical part coating jig provided by the embodiment of the present application. Referring to Fig. 5, in some cases, for example, for the clamping of a spherical part 50 with a smaller diameter, on the basis of the part coating fixture shown in Fig. 3, by appropriately reducing the height of the rib 12 and appropriately increasing the The protruding length of the protruding portion 33, that is, the radial dimension of the protruding portion 33, reduces the distance between the positioning surface 31 and the inner surface of the rib 12, which is suitable for small-sized spherical parts 50.

Similarly, for example, for the clamping of a spherical part 50 with a larger diameter, on the basis of the part coating fixture shown in FIG. The distance between the positioning surface 31 and the inner surface of the rib 12 is relatively large, which is suitable for large-sized spherical parts 50 .

It can be understood that the number of spherical parts 50 that can be clamped in the annular area formed by the supporting surface 13, the inner side of the rib 12 and the positioning surface 31 can be set as required, and adjacent spherical parts 50 can be in contact with each other. , can also have a certain interval.

Fig. 6 is a front view of the coating and clamping mechanism for spherical parts provided in the embodiment of the present application, and Fig. 7 is a schematic diagram of the overall structure of the coating and clamping mechanism for spherical parts provided in the embodiment of the present application.

Referring to Fig. 6 and Fig. 7, the embodiment of the present application also provides a spherical part coating clamping mechanism 200, which includes a mounting base 201 and a plurality of the above-mentioned spherical part coating fixtures 100. It should be noted that the structure of the spherical part coating fixture 100 , principles, functions, etc. have been described in detail above, and will not be repeated here.
