Description

Technical Field

[0001] This utility model relates to the field of ball diameter measurement technology for ball separators, and in particular to a ball diameter measurement device for ball separators. Background Technology

[0002] In the injection molding process of ball separators, the ball diameter is an important quality inspection item. The ball diameter is the key to determining whether the balls in the bearing can rotate freely and whether they can make contact at the bottom. Therefore, it is necessary to measure the ball diameter. The existing measurement method uses two blocks to block the ball separator on a coordinate measuring machine platform. On the one hand, force is applied to the ball separator during the measurement process, which can cause the ball separator to move and make the coordinate measuring machine measurement inaccurate. On the other hand, it is impossible to fix the product measurement position, so it is impossible to build a coordinate system and save the program, and it is impossible to use the same program to measure the same product. Utility Model Content

[0003] The purpose of this invention is to provide a ball diameter measuring device for ball separators, which can meet the measurement needs of ball separators with various diameters.

[0004] This utility model provides a ball diameter measuring device for a ball separator, including a first stop block, a movable pressure block, a guide positioning block, and a multi-hole positioning plate fixedly installed on a three-coordinate measuring platform. The multi-hole positioning plate is provided with a plurality of connecting holes arranged in a rectangular array. The first stop block and the guide positioning block are provided with a plurality of positioning holes corresponding to the connecting holes at intervals. The movable pressure block is provided with symmetrical guide rods, which are slidably passed through the guide positioning block. A spring is sleeved on the guide rod for abutting between the movable pressure block and the positioning guide block. The first stop block is provided with a plurality of triangular positioning notches at intervals along its length on the side near the movable pressure block.

[0005] Furthermore, a nut is threaded onto one end of the guide rod that passes through the guide positioning block.

[0006] Furthermore, the lengths of the two sides of the triangular positioning notch are equal.

[0007] Furthermore, the multiple triangular positioning notches are equally spaced along the length direction of the first stop.

[0008] Furthermore, the included angle between the two sides of the triangular positioning notch is 100°.

[0009] Furthermore, the side of the movable pressure block closest to the first stop is a flat surface, and a soft pad is provided on the flat surface.

[0010] Furthermore, the guide positioning block is provided with symmetrical guide holes, and the axis of the guide holes is parallel to the multi-hole positioning plate.

[0011] Furthermore, a nut is threaded onto one end of the guide rod that passes through the positioning guide block.

[0012] Furthermore, the first stop block has a plurality of first positioning holes corresponding to the connecting holes at equal intervals along its length direction, and the guide positioning block has a plurality of second positioning holes corresponding to the connecting holes at equal intervals along its length direction. The first stop block and the guide positioning block are respectively threaded to the connecting holes on the multi-hole positioning plate by bolts passing through the first positioning holes and the second positioning holes.

[0013] Furthermore, the first stop block, the movable pressure block, and the guide positioning block are all cuboid structures, and the axes of the first positioning hole and the second positioning hole are both perpendicular to the porous positioning plate.

[0014] The technical solution of this utility model is to set a spring fitted on the guide rod between the movable pressure block and the guide positioning block. The spring provides a stable elastic resistance force. With the sliding adjustment of the movable pressure block along the guide rod, the ball separator can be firmly clamped between the movable pressure block and the first stop block, effectively avoiding the ball separator from moving due to external force during the measurement process, and significantly improving the accuracy of the measurement. The rectangular array of connecting holes on the multi-hole positioning plate cooperates with the corresponding positioning holes on the first stop block and the guide positioning block to achieve precise and fixed installation of the first stop block and the guide positioning block on the three-coordinate measuring platform. This facilitates the construction of a measurement coordinate system based on the fixed position and the saving of the measurement program, meeting the need for reusing the same program for measurement of the same product. Multiple triangular positioning notches spaced along the length of the first stop block can accurately position the ball separator. At the same time, combined with the sliding adjustment of the guide rod and the elastic clamping effect of the spring, it can be adapted to the measurement of ball separators with different ball diameters, improving the versatility and applicability of the device.

[0023] Example 1

[0024] like Figures 1-3As shown, this utility model provides a ball diameter measuring device for a ball separator, including a first stop block 1, a movable pressure block 4, a guide positioning block 5, and a multi-hole positioning plate 11 fixedly installed on a three-coordinate measuring platform. The multi-hole positioning plate 11 has multiple connecting holes 12 arranged in a rectangular array for fixing the first stop block 1 and the guide positioning block 5 with bolts. Each connecting hole 12 corresponds to a coordinate position, which facilitates the construction of a coordinate system and saving the program through the three-coordinate measuring platform, making it convenient for subsequent product re-inspection and improving work efficiency.

[0025] The first stop block 1 has multiple first positioning holes 2 at equal intervals along its length, corresponding to the connecting holes 12. The guide positioning block 5 has multiple second positioning holes 7 at equal intervals along its length, corresponding to the connecting holes 12. The first stop block 1 and the guide positioning block 5 are respectively threaded to the connecting holes 12 on the multi-hole positioning plate 11 by bolts passing through the first positioning holes 2 and the second positioning holes 7. The first stop block 1, the movable pressure block 4, and the guide positioning block 5 are all cuboid structures. The axes of the first positioning holes 2 and the second positioning holes 7 are both perpendicular to the multi-hole positioning plate 11. Multiple positioning holes are provided on both the first stop block 1 and the guide positioning block 5 to prevent the tooling from being scrapped if a single positioning hole is damaged.

[0026] The movable pressure block 4 is symmetrically provided with guide rods 6, which are fixedly connected to the movable pressure block 4. The guide positioning block 5 is symmetrically provided with guide holes, the axis of which is parallel to the multi-hole positioning plate 11. The guide rods 6 are slidably inserted into the guide holes of the guide positioning block 5, so that the distance between the movable pressure block 4 and the first stop block 1 can be adjusted. One end of the guide rod 6 that passes through the guide positioning block 5 is threaded with a nut 9 to prevent the guide rod 6 from disengaging from the guide positioning block 5. A spring 8 is sleeved on the guide rod 6 to abut against the movable pressure block 4 and the positioning guide block. The spring 8 is used to clamp and position the ball separator 10, which facilitates clamping of ball separators 10 with various ball diameters.

[0027] To improve the positioning accuracy and stability of the ball separator 10, multiple triangular positioning notches 3 are spaced apart along the length of the first stop 1 near the movable pressure block 4. The multiple triangular positioning notches 3 are equally spaced along the length of the first stop 1, and the lengths of the two sides of the triangular positioning notches 3 are equal. The included angle between the two sides of the triangular positioning notches 3 is 100°. The side of the movable pressure block 4 near the first stop 1 is a plane. When the device clamps the ball separator 10, it forms a three-point positioning through the two sides of the triangular positioning notches 3 and the movable stop. When fixed, it can be clamped by the spring 8.

[0028] A two-millimeter-thick soft pad can be installed on the plane of the movable pressure block 4 near the first stop block 1 to facilitate the differential fixing of ball separators with different outer diameters.

[0029] Example 2

[0030] The difference between this embodiment and embodiment 1 is that the root of the guide rod 6 is hinged to the movable pressure block 4, which can simultaneously press and fix the ball separators 10 of different diameters (the ball separators 10 of different diameters are placed at the triangular positioning notches 3 at different positions, and need to be arranged in order from large to small or from small to large).

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
