[0035] In this embodiment, as shown in the attached Figure 1-10As shown, the extrusion linkage mechanism includes a micro extrusion electric cylinder 33 fixedly mounted on the upper surface of the support frame 1; a push rod 34 is fixedly mounted on the output end of the micro extrusion electric cylinder 33, and a positioning pressure sensor 35 is fixedly connected to the bottom end of the push rod 34, a socket plate 36 is fixedly mounted on the outer wall of the push rod 34, and two guide rods 37 are provided on both sides of the positioning pressure sensor 35, and the two guide rods 37 are fixedly connected to the socket plate 36.

The two guide rods 37 are symmetrically arranged with respect to the positioning pressure sensor 35 , and the outer wall of the guide rod 37 and the inner wall of the socket plate 36 are both designed as smooth surfaces.

[0036] The working principle of the table tennis ball anti-deformation detection device of the present invention is as follows: Step 1: When squeezing the linkage mechanism, first insert the bolts into the mounting plate 23 to fix the mounting plate 23. Then place the table tennis ball 43 on the upper surface of the friction disk 26, and position the table tennis ball 43 through the friction disk 26. Then the controller 44 starts the micro-extrusion electric cylinder 33, and the micro-extrusion electric cylinder 33 pushes the push rod 34 to move downward, and the push rod 34 drives the positioning pressure sensor 35 to move downward, and the positioning pressure sensor 35 can make the squeezing frame 38 move downward. At the same time, the squeezing frame 38 drives the limit shaft ring 39 to move downward, and the limit shaft ring 39 drives the two limit support rings 40 to move downward synchronously, and the limit support ring 40 drives the squeezing shaft 41 to move downward synchronously, and the squeezing shaft 41 can make the friction cover 42 move downward, and the friction cover 42 is squeezed at the top position of the outer wall of the table tennis ball 43. The friction cover 42 can make the table tennis ball 43 firmly fixed at the upper surface of the friction disk 26.

[0037] At the same time, the extrusion frame 38 drives the two guide rods 37 to move upward, and the guide rods 37 move upward along the inner wall of the socket plate 36, so that the two guide rods 37 move upward slightly, and the positioning pressure sensor 35 realizes pressure sensing of the push rod 34. When the pressure value sensed by the positioning pressure sensor 35 is the same as the detection pressure value set by the controller 44, the micro-extrusion electric cylinder 33 is closed through the controller 44, so that the top and bottom of the ping-pong ball 43 can be tested for pressure resistance, and the ping-pong ball 43 can also be positioned and fixed.

[0038] Step 2: During the multi-point synchronous extrusion detection, the controller 44 starts the micro-propelling electric cylinder 2, which drives the detection pressure sensor 45 to move upward, and the detection pressure sensor 45 causes the sleeve slide 3 to move upward, and the sleeve slide 3 can slide along the outer wall of the support frame 1, and the sleeve slide 3 drives the groove ring 4 to move upward, and the groove ring 4 causes multiple hinge blocks 5 to move upward synchronously, and the hinge block 5 drives the connecting shaft 6 to move upward, and the connecting shaft 6 carries the bottom end of the sleeve push rod 7 to move upward, and the top end of the sleeve push rod 7 drives the push shaft 8 to move closer to the table tennis ball 43. Then the push shaft 8 drives the connecting block 9 to move closer to the table tennis ball 43, and the connecting block 9 drives the sleeve block 10 to move closer to the table tennis ball 43, and the sleeve block 10 slides along the outer wall of the sliding shaft 19, and the connecting block 9 moves closer to the table tennis ball 43 along the inner wall of the sleeve block 10.

[0039] Step three, during linkage extrusion, the sleeve block 10 simultaneously drives the two driving shafts 11 to move closer to the ping-pong ball 43, the sleeve block 10 drives the linkage sleeve rod 12 to move closer to the ping-pong ball 43, and at the same time the linkage sleeve rod 12 drives the hinged push rod 13 to drive the concave block 14 to rotate counterclockwise, the concave block 14 drives the sleeve pressure plate 15 to rotate counterclockwise, the sleeve pressure plate 15 rotates counterclockwise along the outer wall of the positioning shaft 16, wherein the support frame 1 supports the bracket 22, the bracket 22 supports the hinged ring 17, the hinged ring 17 supports multiple positioning shafts 16, thereby increasing the stability of the multiple positioning shafts 16. At the same time, the sleeve pressure plate 15 will carry multiple bearing sleeves 20 to rotate counterclockwise, and the bearing sleeves 20 will carry the extrusion balls 21 to rotate counterclockwise, so that the multiple extrusion balls 21 can be squeezed and contacted on the outer wall of the table tennis ball 43. At the same time, the sleeve pressure plate 15 below rotates clockwise, so that the multiple bearing sleeves 20 on the sleeve pressure plate 15 below rotate clockwise, so that the multiple extrusion balls 21 on the sleeve pressure plate 15 below can be squeezed on the outer wall of the table tennis ball 43. When the pressure value sensed by the detection pressure sensor 45 is the same as the detection pressure value set by the controller 44, the micro-propelling electric cylinder 2 is closed by the controller 44, so that the multiple points on the outer wall of the table tennis ball 43 can be covered with pressure resistance detection.

[0040] Step 4: During positioning twisting, the mounting plate 23 supports the two support rods 29, and the mounting plate 23 supports the angle sensor 24, and the mounting plate 23 can also support the reduction motor 32. Then the reduction motor 32 is started by the controller 44, and the reduction motor 32 drives the transmission gear 31 to rotate, and the transmission gear 31 carries the driven gear 30 to mesh and rotate, and the driven gear 30 drives the rotating shaft 25 to rotate, and the rotating shaft 25 drives the two rotating rings 27 to rotate.

[0041] At the same time, the two rotating rings 27 rotate on the shaft ring 28, and the support rod 29 supports the shaft ring 28. The shaft ring 28 can make the rotating shaft 25 rotate stably. At the same time, the rotating shaft 25 drives the friction disk 26 to rotate. The friction disk 26 and the ping-pong ball 43 are firmly squeezed and locked. Therefore, under the action of the squeezing friction force, the friction disk 26 makes the ping-pong ball 43 rotate, and under the action of the squeezing friction force, the ping-pong ball 43 makes the friction cover 42 rotate. The friction cover 42 drives the extrusion rotating shaft 41 to rotate. The extrusion rotating shaft 41 carries two limit support rings 40 on the limit shaft ring 39. Rotate, so that the ping-pong ball 43 can drive multiple extrusion balls 21 to be squeezed and rolled, so that the extrusion balls 21 roll inside the bearing sleeve 20, so that the outer wall of the ping-pong ball 43 can rotate to contact the multiple extrusion balls 21, and the multiple extrusion balls 21 can apply a specified detection pressure to the outer wall of the ping-pong ball 43. The multiple extrusion balls 21 realize multi-point mobile pressure resistance detection on the outer wall of the ping-pong ball 43. When the angle sensor 24 realizes angle sensing of the rotating shaft 25, when the angle value sensed by the angle sensor 24 is thirty-six degrees, the reduction motor 32 is turned off through the controller 44.

[0042] Step 4: When observing and recording, the quality inspector can check whether there are any concave points on the outer wall of the ping-pong ball 43. If the controller 44 produces a concave point, the compression test is unqualified. When the outer wall of the ping-pong ball 43 does not produce a concave point, the ping-pong ball 43 is detected as a qualified product.
